Programs & Examples On #Ready

If you need to call different functions for different ng-repeats on the same controller you can try something like this:

The directive:

var module = angular.module('testApp', [])
    .directive('onFinishRender', function ($timeout) {
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            if (scope.$last === true) {
            $timeout(function () {
                scope.$emit(attr.broadcasteventname ? attr.broadcasteventname : 'ngRepeatFinished');
            });
            }
        }
    }
});

In your controller, catch events with $on:

$scope.$on('ngRepeatBroadcast1', function(ngRepeatFinishedEvent) {
// Do something
});

$scope.$on('ngRepeatBroadcast2', function(ngRepeatFinishedEvent) {
// Do something
});

In your template with multiple ng-repeat

<div ng-repeat="item in collection1" on-finish-render broadcasteventname="ngRepeatBroadcast1">
    <div>{{item.name}}}<div>
</div>

<div ng-repeat="item in collection2" on-finish-render broadcasteventname="ngRepeatBroadcast2">
    <div>{{item.name}}}<div>
</div>

You can also relax your CSP for styles by adding style-src 'self' 'unsafe-inline';

"content_security_policy": "default-src 'self' style-src 'self' 'unsafe-inline';" 

This will allow you to keep using inline style in your extension.

Important note

As others have pointed out, this is not recommended, and you should put all your CSS in a dedicated file. See the OWASP explanation on why CSS can be a vector for attacks (kudos to @ KayakinKoder for the link).

The script package does exactly what you're looking for: https://atom.io/packages/script

The package's documentation also contains the key mappings, which you can easily customize.

[TestMethod]
public void EnsureKWLLibrariesAreAll64Bit()
{
    var assemblies = Assembly.GetExecutingAssembly().GetReferencedAssemblies().Where(x => x.FullName.StartsWith("YourCommonProjectName")).ToArray();
    foreach (var assembly in assemblies)
    {
        var myAssemblyName = AssemblyName.GetAssemblyName(assembly.FullName.Split(',')[0] + ".dll");
        Assert.AreEqual(ProcessorArchitecture.MSIL, myAssemblyName.ProcessorArchitecture);
    }
}

You can do it the DOM way as well:

var div = document.getElementById('cart_item');
while(div.firstChild){
    div.removeChild(div.firstChild);
}

Off course, myDico.Values is List<List<MyType>>.

Use Linq if you want to flattern your lists

var items = myDico.SelectMany (d => d.Value).ToList();

You can convert JSON Date to normal date format in JavaScript.

var date = new Date(parseInt(jsonDate.substr(6)));

i solved this by http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/ just uncomment or add this:

RewriteBase /
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

to your .htaccess file

you could use key value to reset state when need, pass props to state it's not a good practice , because you have uncontrolled and controlled component in one place. Data should be in one place handled read this https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#recommendation-fully-uncontrolled-component-with-a-key

From the docs:-

Your app gradle file now has to explicitly list com.google.firebase:firebase-core as a dependency for Firebase services to work as expected.

Add:

 implementation 'com.google.firebase:firebase-core:16.0.1'

and in top level gradle file use the latest version of google play services:

classpath 'com.google.gms:google-services:4.0.2'

https://firebase.google.com/support/release-notes/android

https://bintray.com/android/android-tools/com.google.gms.google-services

Note:

You need to add the google() repo in the top level gradle file, as specified in the firebase docs and also it should be before jcenter():

 buildscript {
  repositories {
          google()
          jcenter()
      }



dependencies {
  classpath 'com.android.tools.build:gradle:3.1.3'
  classpath 'com.google.gms:google-services:4.0.2'
   }
}

allprojects {
     repositories {
              google()
             jcenter()
  }
}

task clean(type: Delete) {
  delete rootProject.buildDir
 }

The error you're getting is that self.adj doesn't already have a key 0. You're trying to append to a list that doesn't exist yet.

Consider using a defaultdict instead, replacing this line (in __init__):

self.adj = {}

with this:

self.adj = defaultdict(list)

You'll need to import at the top:

from collections import defaultdict

Now rather than raise a KeyError, self.adj[0].append(edge) will create a list automatically to append to.

Instead of adding File, add class. File->New->Class. That fixed my issue.

Construct some data

df <- data.frame( name=c("John", "Adam"), date=c(3, 5) )

Extract exact matches:

subset(df, date==3)

  name date
1 John    3

Extract matches in range:

subset(df, date>4 & date<6)

  name date
2 Adam    5

The following syntax produces identical results:

df[df$date>4 & df$date<6, ]

  name date
2 Adam    5

#modal {
    display: flex;
    justify-content: space-around;
    align-items: center;
    position: fixed;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
}

inside it can be any element with diffenet width, height or without. all are centered.

Use android:background property for that edittext. Pass your drawable folder image to it. For example,

android:background="@drawable/abc.png"

I'm having the same problem, reading some answers (posted here), I saw my certificate expired.

Just create a new one from my start project. Then at certificates manager deleted the expired certificate.

Now everything compiles fine.

In my case above mentioned methods work fine with php but when i try to upload files with these methods in node.js then i have some problem. So instead of using $http({..,..,...}) use the normal jquery ajax.

For select file use this

<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this)"/>

And in controller

$scope.uploadFile = function(element) {   
var data = new FormData();
data.append('file', $(element)[0].files[0]);
jQuery.ajax({
      url: 'brand/upload',
      type:'post',
      data: data,
      contentType: false,
      processData: false,
      success: function(response) {
      console.log(response);
      },
      error: function(jqXHR, textStatus, errorMessage) {
      alert('Error uploading: ' + errorMessage);
      }
 });   
};

Daniel's answer seems to work fine for now, but please note that generating absolute urls using twig's asset function is now deprecated:

DEPRECATED - Generating absolute URLs with the Twig asset() function was deprecated in 2.7 and will be removed in 3.0. Please use absolute_url() instead.

Here's the official announcement: http://symfony.com/blog/new-in-symfony-2-7-the-new-asset-component#template-function-changes

You have to use the absolute_url twig function:

{# Symfony 2.6 #}
{{ asset('logo.png', absolute = true) }}

{# Symfony 2.7 #}
{{ absolute_url(asset('logo.png')) }}

It is interesting to note that it also works with path function:

{{ absolute_url(path('index')) }}

This got me the value and text of the selected options for the jQuery multiselect.js plugin:

$("#selectBox").multiSelect({
    afterSelect: function(){
        var selections = [];
        $("#selectBox option:selected").each(function(){
            var optionValue = $(this).val();
            var optionText = $(this).text();
            console.log("optionText",optionText);                
            // collect all values
            selections.push(optionValue);
        });

        // use array "selections" here.. 
    }
});   

very usefull if you need it for your "onChange" event ;)

I am getting similar errors recently because recent JDKs (and browsers, and the Linux TLS stack, etc.) refuse to communicate with some servers in my customer's corporate network. The reason of this is that some servers in this network still have SHA-1 certificates.

Please see: https://www.entrust.com/understanding-sha-1-vulnerabilities-ssl-longer-secure/ https://blog.qualys.com/ssllabs/2014/09/09/sha1-deprecation-what-you-need-to-know

If this would be your current case (recent JDK vs deprecated certificate encription) then your best move is to update your network to the proper encription technology.

In case that you should provide a temporal solution for that, please see another answers to have an idea about how to make your JDK trust or distrust certain encription algorithms:

How to force java server to accept only tls 1.2 and reject tls 1.0 and tls 1.1 connections

Anyway I insist that, in case that I have guessed properly your problem, this is not a good solution to the problem and that your network admin should consider removing these deprecated certificates and get a new one.

Pure CSS method

It is possible to center a video inside an element just like a cover sized background-image without JS using the object-fit attribute or CSS Transforms.

2021 answer: object-fit

As pointed in the comments, it is possible to achieve the same result without CSS transform, but using object-fit, which I think it's an even better option for the same result:

.video-container {
    height: 300px;
    width: 300px;
    position: relative;
}

.video-container video {
  width: 100%;
  height: 100%;
  position: absolute;
  object-fit: cover;
  z-index: 0;
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
    <video autoplay muted loop>
        <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
    </video>
    <div class="caption">
      <h2>Your caption here</h2>
    </div>
</div>

Previous answer: CSS Transform

You can set a video as a background to any HTML element easily thanks to transform CSS property.

Note that you can use the transform technique to center vertically and horizontally any HTML element.

.video-container {
  height: 300px;
  width: 300px;
  overflow: hidden;
  position: relative;
}

.video-container video {
  min-width: 100%;
  min-height: 100%;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translateX(-50%) translateY(-50%);
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
  <video autoplay muted loop>
    <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
  </video>
  <div class="caption">
    <h2>Your caption here</h2>
  </div>
</div>

This always works for me:

import android.app.Activity;
import android.content.Context;

public class yourClass {

 Context ctx;

 public yourClass (Handler handler, Context context) {
 super(handler);
    ctx = context;
 }

 //Use context (ctx) in your code like this:
 block1 = new Droid(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic), 100, 10);
 //OR
 builder.setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic));
 //OR
 final Intent intent = new Intent(ctx, MainActivity.class);
 //OR
 NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
 //ETC...

}

Not related to this question but example using a Fragment to access system resources/activity like this:

public boolean onQueryTextChange(String newText) {
 Activity activity = getActivity();
 Context context = activity.getApplicationContext();
 returnSomething(newText);
 return false;
}

View customerInfo = getActivity().getLayoutInflater().inflate(R.layout.main_layout_items, itemsLayout, false);
 itemsLayout.addView(customerInfo);

You can use the following code to hide a table column..

JQuery("tableName").hideCol("colName");

And you can use the following code to show it again.

JQuery("tableName").showCol("colName");

For your question, you can call the hideCol() code on the document.ready(), and you can bind the showCol() code on the dialog's edit/click event.

The 'keyof' solution mentioned above works. But if the variable is used only once e.g looping through an object etc, you can also typecast it.

for (const key in someObject) {
    sampleObject[key] = someObject[key as keyof ISomeObject];
}

       // **For multiple permission you can use this code :**

       // **First:**
//Write down in onCreate method.

         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    requestPermissions(new String[]{
                                    android.Manifest.permission.READ_EXTERNAL_STORAGE,
                                    android.Manifest.permission.CAMERA},
                            MY_PERMISSIONS_REQUEST);

         }

        //**Second:**
    //Write down in a activity.
     @Override
        public void onRequestPermissionsResult(int requestCode,
                                               String permissions[], int[] grantResults) {
            switch (requestCode) {
                case MY_PERMISSIONS_REQUEST:

                    if (grantResults.length > 0
                            && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                        new Handler().postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                progressBar.setVisibility(View.GONE);
                                Intent i = new Intent(SplashActivity.this,
                                        HomeActivity.class);
                                startActivity(i);
                                finish();
                            }
                        }, SPLASH_DISPLAY_LENGTH);

                    } else {
                        finish();
                    }
                    return;
            }
        }

This works for me...

Literally dozens of answers in this and linked questions and elsewhere at SE, all of which are deficient in this way or another, have clearly shown that Windows doesn't provide a reliable built-in console utility. So, it's time to roll out your own.

The following C code, based on Detect if program is running with full administrator rights, works in Win2k+¹, anywhere and in all cases (UAC, domains, transitive groups...) - because it does the same as the system itself when it checks permissions. It signals of the result both with a message (that can be silenced with a switch) and exit code.

It only needs to be compiled once, then you can just copy the .exe everywhere - it only depends on kernel32.dll and advapi32.dll (I've uploaded a copy).

chkadmin.c:

#include <malloc.h>
#include <stdio.h>
#include <windows.h>
#pragma comment (lib,"Advapi32.lib")

int main(int argc, char** argv) {
    BOOL quiet = FALSE;
    DWORD cbSid = SECURITY_MAX_SID_SIZE;
    PSID pSid = _alloca(cbSid);
    BOOL isAdmin;

    if (argc > 1) {
        if (!strcmp(argv[1],"/q")) quiet=TRUE;
        else if (!strcmp(argv[1],"/?")) {fprintf(stderr,"Usage: %s [/q]\n",argv[0]);return 0;}
    }

    if (!CreateWellKnownSid(WinBuiltinAdministratorsSid,NULL,pSid,&cbSid)) {
        fprintf(stderr,"CreateWellKnownSid: error %d\n",GetLastError());exit(-1);}

    if (!CheckTokenMembership(NULL,pSid,&isAdmin)) {
        fprintf(stderr,"CheckTokenMembership: error %d\n",GetLastError());exit(-1);}

    if (!quiet) puts(isAdmin ? "Admin" : "Non-admin");
    return !isAdmin;
}

¹_{MSDN claims the APIs are XP+ but this is false. CheckTokenMembership is 2k+ and the other one is even older. The last link also contains a much more complicated way that would work even in NT.}

Use the % operator with a string:

irb(main):001:0> "%03d" % 5
=> "005"

The left-hand-side is a printf format string, and the right-hand side can be a list of values, so you could do something like:

irb(main):002:0> filename = "%s/%s.%04d.txt" % ["dirname", "filename", 23]
=> "dirname/filename.0023.txt"

Here's a printf format cheat sheet you might find useful in forming your format string. The printf format is originally from the C function printf, but similar formating functions are available in perl, ruby, python, java, php, etc.

Add a linefeed ("\n") to the output:

<textarea>Hello


Bybye</textarea>

Will have a newline in it.

WAMP is an acronym for Windows (OS), Apache (web-server), MySQL (database), PHP (language).

XAMPP and WampServer are both free packages of WAMP, with additional applications/tools, put together by different people. There are also other WAMPs such as UniformServer. And there are commercial WAMPs such as WampDeveloper (what I use).

Their differences are in the format/structure of the package, the configurations, and the included management applications.

IIS is a web-server application just like Apache is, except it's made by Microsoft and is Windows only (Apache runs on both Windows and Linux). IIS is also more geared towards using ASP.NET (vs. PHP) and "SQL Server" (vs. MySQL), though it can use PHP and MySQL too.

I came here because the Remove button was not available from Add/Remove programs. It was saying "Node.js cannot be removed".

This worked:

1. Got the .msi of my installed Node version. Ran it to repair the installation just in case.
2. Opened the Administrator command prompt and ran msiexec /uninstall <node.msi>.

You can add simple white space with quotes sign: {" "}

Also you can use template literals, which allow to insert, embedd expressions (code inside curly braces):

`${2 * a + b}.?!=-` // Notice this sign " ` ",its not normal quotes.

Try this

<input type="submit" 
       value="HOME" 
       onclick="goHome()" 
       style="font-size : 20px; width: 100%; height: 100px;" /> 

There is actually only a single layer of containers. You can virtually create a "file-system" like layered storage, but in reality everything will be in 1 layer, the container in which it is.

For creating a virtual "file-system" like storage, you can have blob names that contain a '/' so that you can do whatever you like with the way you store. Also, the great thing is that you can search for a blob at a virtual level, by giving a partial string, up to a '/'.

These 2 things, adding a '/' to a path and a partial string for search, together create a virtual "file-system" storage.

I tried all of the other suggestions in this thread and nothing worked - however I found this thread from the Jetbrains site and their solution did work for me. I hope it helps some of you as well. Specifically this suggestion worked:

• Close the IDE
• Delete the /Users/yourname/Library/Caches/IntelliJIdeaXXX/ directory (whatever your version is)
• Start IDE and re-import project from scratch as Maven project

Worked like a charm for me, good luck! :wave:

btw I'm using IntelliJ IDEA Ultimate 2020.2 on a Mac.

std::move itself doesn't really do much. I thought that it called the moved constructor for an object, but it really just performs a type cast (casting an lvalue variable to an rvalue so that the said variable can be passed as an argument to a move constructor or assignment operator).

So std::move is just used as a precursor to using move semantics. Move semantics is essentially an efficient way for dealing with temporary objects.

Consider Object A = B + C + D + E + F;

This is nice looking code, but E + F produces a temporary object. Then D + temp produces another temporary object and so on. In each normal "+" operator of a class, deep copies occur.

For example

Object Object::operator+ (const Object& rhs) {
    Object temp (*this);
    // logic for adding
    return temp;
}

The creation of the temporary object in this function is useless - these temporary objects will be deleted at the end of the line anyway as they go out of scope.

We can rather use move semantics to "plunder" the temporary objects and do something like

 Object& Object::operator+ (Object&& rhs) {
     // logic to modify rhs directly
     return rhs;
 }

This avoids needless deep copies being made. With reference to the example, the only part where deep copying occurs is now E + F. The rest uses move semantics. The move constructor or assignment operator also needs to be implemented to assign the result to A.

To find the minimum value of a list, you might just as well use min:

x = min(float(s) for s in l) # min of a generator

Or, if you want the result as a string, rather than a float, use a key function:

x = min(l, key=float)

It is the container of the Grid that is imposing on its width. In this case, that's a ListBoxItem, which is left-aligned by default. You can set it to stretch as follows:

<ListBox>
    <!-- other XAML omitted, you just need to add the following bit -->
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="HorizontalAlignment" Value="Stretch"/>
        </Style>

Both IP and DNS can be specified with the keytool additional argument -ext SAN=dns:abc.com,ip:1.1.1.1

Example:

keytool -genkeypair -keystore <keystore> -dname "CN=test, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown" -keypass <keypwd> -storepass <storepass> -keyalg RSA -alias unknown -ext SAN=dns:test.abc.com,ip:1.1.1.1

date -j -f "%Y-%m-%d %H:%M:%S" "2020-04-07 00:00:00" "+%s"

It will print the dynamic seconds when without %H:%M:%S and 00:00:00.

For non-anonymous functions

function foo()
{ 
    alert(arguments.callee.name)
}

But in case of an error handler the result would be the name of the error handler function, wouldn't it?

These are exactly the same. android:onClick was added in API level 4 to make it easier, more Javascript-web-like, and drive everything from the XML. What it does internally is add an OnClickListener on the Button, which calls your DoIt method.

Here is what using a android:onClick="DoIt" does internally:

Button button= (Button) findViewById(R.id.buttonId);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        DoIt(v);
    }
});

The only thing you trade off by using android:onClick, as usual with XML configuration, is that it becomes a bit more difficult to add dynamic content (programatically, you could decide to add one listener or another depending on your variables). But this is easily defeated by adding your test within the DoIt method.

public class MainActivity extends AppCompatActivity {

    public void clickMe (View view) {

        MediaPlayer mp = MediaPlayer.create(this, R.raw.xxx);
        mp.start();

    }

create a button with a method could be called when the button pressed (onCreate),

then create a variable for (MediaPlayer) class with the path of your file

MediaPlayer mp = MediaPlayer.create(this, R.raw.xxx);

finally run start method in that class

mp.start();

the file will run when the button pressed, hope this was helpful!

The lack of an exponential operator for C# was a big annoyance for us when looking for a new language to convert our calculation software to from the good ol' vb6.

I'm glad we went with C# but it still annoys me whenever I'm writing a complex equation including exponents. The Math.Pow() method makes equations quite hard to read IMO.

Our solution was to create a special DoubleX class where we override the ^-operator (see below)

This works fairly well as long as you declare at least one of the variables as DoubleX:

DoubleX a = 2;
DoubleX b = 3;

Console.WriteLine($"a = {a}, b = {b}, a^b = {a ^ b}");

or use an explicit converter on standard doubles:

double c = 2;
double d = 3;

Console.WriteLine($"c = {c}, d = {d}, c^d = {c ^ (DoubleX)d}");     // Need explicit converter

One problem with this method though is that the exponent is calculated in the wrong order compared to other operators. This can be avoided by always putting an extra ( ) around the operation which again makes it a bit harder to read the equations:

DoubleX a = 2;
DoubleX b = 3;

Console.WriteLine($"a = {a}, b = {b}, 3+a^b = {3 + a ^ b}");        // Wrong result
Console.WriteLine($"a = {a}, b = {b}, 3+a^b = {3 + (a ^ b)}");      // Correct result

I hope this can be of help to others who uses a lot of complex equations in their code, and maybe someone even has an idea of how to improve this method?!

I just gave this a whirl in both Chrome and Firefox and IE10.

As mentioned above - make sure that you have marked up with type = "button", "reset", "submit" etc to ensure that it correctly cascades and chooses the correct button.

Perhaps also setting all of them to have the same form (ie all as that worked for me)

I think it could be used for "retroactively forking"

If you have a Git repo, and have now decided that it should have forked another repo. Retroactively you would like it to become a fork, without disrupting the team that uses the repo by needing them to target a new repo.

But I could be wrong.

As per The Zen of Python (if you are wondering whether your code is "Pythonic", that's the place to go):

• Beautiful is better than ugly.
• Explicit is better than implicit.
• Simple is better than complex.
• Flat is better than nested.
• Readability counts.

The Pythonic way of getting the sorted intersection of two sets is:

>>> sorted(set(a).intersection(xyz))
[0, 4, 6, 7, 9]

Or those elements that are xyz but not in a:

>>> sorted(set(xyz).difference(a))
[12, 242]

But for a more complicated loop you may want to flatten it by iterating over a well-named generator expression and/or calling out to a well-named function. Trying to fit everything on one line is rarely "Pythonic".

Update following additional comments on your question and the accepted answer

I'm not sure what you are trying to do with enumerate, but if a is a dictionary, you probably want to use the keys, like this:

>>> a = {
...     2: 'Turtle Doves',
...     3: 'French Hens',
...     4: 'Colly Birds',
...     5: 'Gold Rings',
...     6: 'Geese-a-Laying',
...     7: 'Swans-a-Swimming',
...     8: 'Maids-a-Milking',
...     9: 'Ladies Dancing',
...     0: 'Camel Books',
... }
>>>
>>> xyz = [0, 12, 4, 6, 242, 7, 9]
>>>
>>> known_things = sorted(set(a.iterkeys()).intersection(xyz))
>>> unknown_things = sorted(set(xyz).difference(a.iterkeys()))
>>>
>>> for thing in known_things:
...     print 'I know about', a[thing]
...
I know about Camel Books
I know about Colly Birds
I know about Geese-a-Laying
I know about Swans-a-Swimming
I know about Ladies Dancing
>>> print '...but...'
...but...
>>>
>>> for thing in unknown_things:
...     print "I don't know what happened on the {0}th day of Christmas".format(thing)
...
I don't know what happened on the 12th day of Christmas
I don't know what happened on the 242th day of Christmas

I think if you don't consider the VM, it is Integer.MaxValue

I can share few points where&why to use node js.

1. For realtime applications like chat,collaborative editing better we go with nodejs as it is event base where fire event and data to clients from server.
2. Simple and easy to understand as it is javascript base where most of people have idea.
3. Most of current web applications going towards angular js&backbone, with node it is easy to interact with client side code as both will use json data.
4. Lot of plugins available.

Drawbacks:-

1. Node will support most of databases but best is mongodb which won't support complex joins and others.
2. Compilation Errors...developer should handle each and every exceptions other wise if any error accord application will stop working where again we need to go and start it manually or using any automation tool.

Conclusion:- Nodejs best to use for simple and real time applications..if you have very big business logic and complex functionality better should not use nodejs. If you want to build an application along with chat and any collaborative functionality.. node can be used in specific parts and remain should go with your convenience technology.

import csv
cols = [' V1', ' I1'] # define your columns here, check the spaces!
data = [[] for col in cols] # this creates a list of **different** lists, not a list of pointers to the same list like you did in [[]]*len(positions) 
with open('data.csv', 'r') as f:
    for rec in csv.DictReader(f):
        for l, col in zip(data, cols):
            l.append(float(rec[col]))
print data

# [[3.0, 3.0], [0.01, 0.01]]

Just try this:

Bitmap bitmap = BitmapFactory.decodeFile("/path/images/image.jpg");
ByteArrayOutputStream blob = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0 /* Ignored for PNGs */, blob);
byte[] bitmapdata = blob.toByteArray();

If bitmapdata is the byte array then getting Bitmap is done like this:

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);

Returns the decoded Bitmap, or null if the image could not be decoded.

About "can it be that 0 errors and IsValid == false": here's MVC source code from https://github.com/Microsoft/referencesource/blob/master/System.Web/ModelBinding/ModelStateDictionary.cs#L37-L41

public bool IsValid {
    get {
        return Values.All(modelState => modelState.Errors.Count == 0);
    }
}

Now, it looks like it can't be. Well, that's for ASP.NET MVC v1.

What worked for me is using _outline not _outlined after the icon name.

<mat-icon>info</mat-icon>

vs

<mat-icon>info_outline</mat-icon>

If you specify image as well as build, then Compose names the built image with the webapp and optional tag specified in image:

build: ./dir
image: webapp:tag

This results in an image named webapp and tagged tag, built from ./dir.

https://docs.docker.com/compose/compose-file/#build

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

I ran into this as well - I did all of my development on a Lenovo IdeaTab A2107A-F and could run development builds on it, and even release signed APKs (installed with adb install) with no issues. Once it was published in Alpha test mode and available on Google Play I received the "incompatible with your device" error message.

It turns out I had placed in my AndroidManifest.xml the following from a tutorial:

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.CAMERA" />

Well, the Lenovo IdeaTab A2107A-F doesn't have an autofocusing camera on it (which I learned from http://www.phonearena.com/phones/Lenovo-IdeaTab-A2107_id7611, under Cons: lacks autofocus camera). Regardless of whether I was using that feature, Google Play said no. Once that was removed I rebuilt my APK, uploaded it to Google Play, and sure enough my IdeaTab was now in the compatible devices list.

So, double-check every <uses-feature> and if you've been doing some copy-paste from the web check again. Odds are you requested some feature you aren't even using.

If you want to create a garage and fill it up with new cars that can be accessed later, use this code:

for (int i = 0; i < garage.length; i++)
     garage[i] = new Car("argument");

Also, the cars are later accessed using:

garage[0];
garage[1];
garage[2];
etc.

Well generally you shouldn't need to classify an element specified by id, because id is always unique, but if you really need to, the following should work:

div#content.sectionA {
    /* ... */
}

int counter = 0;

for(int i = 1; ; i++) {
    if(isPrime(i)
        counter++;

    if(counter == userInput) {
        print(i);
        break;
    }
}

Edit: Your prime function could use a bit of work. Here's one that I have written:

private static boolean isPrime(long n) {
    if(n < 2)
        return false;

    for (long i = 2; i * i <= n; i++) {
        if (n % i == 0)
            return false;
    }
    return true;
}

Note - you only need to go up to sqrt(n) when looking at factors, hence the i * i <= n

You could use PHP's json_decode function:

$url = "http://urlToYourJsonFile.com";
$json = file_get_contents($url);
$json_data = json_decode($json, true);
echo "My token: ". $json_data["access_token"];

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. text

Generally issues like this are related to any of the following need to be looked at:

• firewall settings from the web server to the database server
• connection string errors
• enable the appropriate protocol pipes/ tcp-ip

Try connecting to sql server with sql management server on the system that sql server is installed on and work from there. Pay attention to information in the errorlogs.

There are three key XML attributes for custom FABs:

• app:fabSize: Either "mini" (40dp), "normal"(56dp)(default) or "auto"
• app:fabCustomSize: This will decide the overall FAB size.
• app:maxImageSize: This will decide the icon size.

Example:

app:fabCustomSize="64dp" 
app:maxImageSize="32dp"

The FAB padding (the space between the icon and the background circle, aka ripple) is calculated implicitly by:

4-edge padding = (fabCustomSize - maxImageSize) / 2.0 = 16

Note that the margins of the fab can be set by the usual android:margin xml tag properties.

Google basis (free) does not provide address verification (Geocoding) as there is no UK postcode license.

This means postcode searches are very in-accurate. The proximity search is very poor, even for town searches, often not recognising locations.

This is why Google have a premier and a enterprise solution which still is more expensive and not as good as business mapping specialists like bIng and Via Michelin who also have API's.

As a free lance developer, so serious business would use Google as the system is weak and really provides a watered down solution.

Datatables supports HTML5 data-* attributes for this functionality.

It supports multiple columns in the sort order (it's 0-based)

<table data-order="[[ 1, 'desc' ], [2, 'asc' ]]">
    <thead>
        <tr>
            <td>First</td>
            <td>Another column</td>
            <td>A third</td>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>z</td>
            <td>1</td>
            <td>$%^&*</td>
        </tr>
        <tr>
            <td>y</td>
            <td>2</td>
            <td>*$%^&</td>
        </tr>
    </tbody>
</table>

Now my jQuery is simply $('table').DataTables(); and I get my second and third columns sorted in desc / asc order.

Here's some other nice attributes for the <table> that I find myself reusing:

data-page-length="-1" will set the page length to All (pass 25 for page length 25)...

data-fixed-header="true" ... Make a guess

You could possibly

• make a new class inherited from the Class ImageView and
• override the Method onDraw. Call super.onDraw() in that method first and
• then draw some Text you want to display.

if you do it that way, you can use this as a single Layout Component which makes it easier to layout together with other components.

I would like to suggest additional solution to fix this issue. So, I recommend to reinstall/install the latest Windows SDK. In my case it has helped me to fix the issue when using Qt with MSVC compiler to debug a program.

While an old question, I've just dealt with a variant of it, but none of the solutions here were applicable, so I found another, and am adding it for posterity. Yes, I know the OP said they were aware of this option and it didn't suit them, but for anyone following afterwards it might prove useful.

In my case, I want to test for the availability of a local apt-cacher-ng service from a docker build. That means absolutely nothing can be installed prior to the test. No nc, nmap, expect, telnet or python. perl however is present, along with the core libraries, so I used this:

perl -MIO::Socket::INET -e 'exit(! defined( IO::Socket::INET->new("172.17.42.1:3142")))'

The easiest and least confusing solution:

a = raw_input("Enter a: ")
b = raw_input("Enter b: ")
print "a + b as strings: %s" % a  + b
a = int(a)
b = int(b)
c = a + b
print "a + b as integers: %d" % c

I found this on http://freecodeszone.blogspot.com/

- (UIImage *)resizeImage:(UIImage*)image newSize:(CGSize)newSize {
    CGRect newRect = CGRectIntegral(CGRectMake(0, 0, newSize.width, newSize.height));
    CGImageRef imageRef = image.CGImage;

    UIGraphicsBeginImageContextWithOptions(newSize, NO, 0);
    CGContextRef context = UIGraphicsGetCurrentContext();

    CGContextSetInterpolationQuality(context, kCGInterpolationHigh);
    CGAffineTransform flipVertical = CGAffineTransformMake(1, 0, 0, -1, 0, newSize.height);

    CGContextConcatCTM(context, flipVertical);
    CGContextDrawImage(context, newRect, imageRef);

    CGImageRef newImageRef = CGBitmapContextCreateImage(context);
    UIImage *newImage = [UIImage imageWithCGImage:newImageRef];

    CGImageRelease(newImageRef);
    UIGraphicsEndImageContext();

    return newImage;
}

TreeSize professional has what you want. but it focus on the sizes of folders and files.

Try that:

  var defaultEmailNews = "Email address";
  $('input[name=email]').focus(function() {
    if($(this).val() == defaultEmailNews) $(this).val("");
  });

  $('input[name=email]').focusout(function() {
    if($(this).val() == "") $(this).val(defaultEmailNews);
  });

Removing the below from the ~/.gitattributes file

* text=auto

will prevent git from checking line-endings in the first-place.

Criteria is an object-oriented API, while HQL means string concatenation. That means all of the benefits of object-orientedness apply:

1. All else being equal, the OO version is somewhat less prone to error. Any old string could get appended into the HQL query, whereas only valid Criteria objects can make it into a Criteria tree. Effectively, the Criteria classes are more constrained.
2. With auto-complete, the OO is more discoverable (and thus easier to use, for me at least). You don't necessarily need to remember which parts of the query go where; the IDE can help you
3. You also don't need to remember the particulars of the syntax (like which symbols go where). All you need to know is how to call methods and create objects.

Since HQL is very much like SQL (which most devs know very well already) then these "don't have to remember" arguments don't carry as much weight. If HQL was more different, then this would be more importatnt.

I use spring boot, so i can simple use:

File file = ResourceUtils.getFile("classpath:myfile.xml");

Before I start, I'd like to note that I can't actually test this since your script reads data from a file that I don't have.

'T' is defined in a local scope for the declared function. In the first instance 'T' is assigned the value of 'data[2]' because the conditional statement above apparently evaluates to True. Since the second call to the function causes the 'UnboundLocalError' exception to occur, the local variable 'T' is getting set and the conditional assignment is never getting triggered.

Since you appear to want to return the first bit of data in the file that matches your conditonal statement, you might want to modify you function to look like this:

def temp_sky(lreq, breq):
    for line in tfile:
        data = line.split()
        if ( abs(float(data[0]) - lreq) <= 0.1 and abs(float(data[1]) - breq) <= 0.1):            
            return data[2]
    return None

That way the desired value gets returned when it is found, and 'None' is returned when no matching data is found.

You should use getFullYear() instead of getYear(). getYear() returns the actual year minus 1900 (and so is fairly useless).

Thus a date marking exactly one year from the present moment would be:

var oneYearFromNow = new Date();
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);

Note that the date will be adjusted if you do that on February 29.

Similarly, you can get a date that's a month from now via getMonth() and setMonth(). You don't have to worry about "rolling over" from the current year into the next year if you do it in December; the date will be adjusted automatically. Same goes for day-of-month via getDate() and setDate().

<div class="row">
    <div class="col-lg-3">
       <div class="affix">
           fixed position 
        </div>
    </div>
    <div class="col-lg-9">
       Normal data enter code here
    </div>
</div>

WARNING: This deletes all commits on the email branch. It's like deleting the email branch and creating it anew at the head of the staging branch.

The easiest way to do it:

//the branch you want to overwrite
git checkout email 

//reset to the new branch
git reset --hard origin/staging

// push to remote
git push -f

Now the email branch and the staging are the same.

In Laravel 5.1+, you can use the value() instead of pluck.

To get first occurence, You can either use

DB::table('users')->value('name');

or use,

DB::table('users')->where('id', 1)->pluck('name')->first();

Swift implementation:

class KeyboardStateListener: NSObject
{
  static var shared = KeyboardStateListener()
  var isVisible = false

  func start() {
    let nc = NSNotificationCenter.defaultCenter()
    nc.addObserver(self, selector: #selector(didShow), name: UIKeyboardDidShowNotification, object: nil)
    nc.addObserver(self, selector: #selector(didHide), name: UIKeyboardDidHideNotification, object: nil)
  }

  func didShow()
  {
    isVisible = true
  }

  func didHide()
  {
    isVisible = false
  } 
}

Because swift doesn't execute class load method on startup it is important to start this service on app launch:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool
{
  ...    
  KeyboardStateListener.shared.start() 
}

I suggest Oj as it is waaaaaay faster than the standard JSON library.

Another solution i´ve used is to move the button instead of disabling it. In that case you don´t have those "disable" problems. Finally what you really want is people not to press twice, if the button is not there they can´t do it.

You may also replace it with another button.

The simple solution is to put it in an iframe and hope that the user has a plug-in that supports it.

(I don't, the Acrobat plugin has been such a resource hog and source of instability that I make a point to remove it from any browser that it touches).

The complicated, but relative popular solution is to display it in a flash applet.

You have to do two steps:

1. Put all your files (css,js,html code, etc.) into the public folder.
2. Use url({{ URL::asset('images/slides/2.jpg') }}) where images/slides/2.jpg is path of your content.

Similarly you can call js, css etc.

Just use dynamic as the argument:

var list = new List<dynamic>();

On my end, the problem was an unsuccessful connection to the VPN (while working from home). And yeah, the connectionString was using a context from remote server. Which resulted in the following error:

  <ExceptionMessage>The network path was not found</ExceptionMessage>
  <ExceptionType>System.ComponentModel.Win32Exception</ExceptionType>

I needed something like this for a game's control configuration UI, so I compiled a list for the standard US keyboard layout keycodes and mapped them to their respective key names.

Here's a fiddle that contains a map for code -> name and visi versa: http://jsfiddle.net/vWx8V/

If you want to support other key layouts you'll need to modify these maps to accommodate for them separately.

That is unless you were looking for a list of keycode values that included the control characters and other special values that are not (or are rarely) possible to input using a keyboard and may be outside of the scope of the keydown/keypress/keyup events of Javascript. Many of them are control characters or special characters like null (\0) and you most likely won't need them.

Notice that the number of keys on a full keyboard is less than many of the keycode values.

You can use ArgbEvaluatorCompat class above API 11.

implementation 'com.google.android.material:material:1.0.0' 


ValueAnimator colorAnim = ValueAnimator.ofObject(new ArgbEvaluatorCompat(), startColor, endColor);
colorAnim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            mTargetColor = (int) animation.getAnimatedValue();
        }
    });
colorAnim.start();

For the difference between A1 and Today's date you could enter: =ABS(TODAY()-A1)

which returns the (fractional) number of days between the dates.

You're likely getting a #VALUE! error in your formula because Excel treats dates as numbers.

Here's my utility method for getting the local IP address, assuming you are looking for an IPv4 address and the machine only has one real network interface. It could easily be refactored to return an array of IP addresses for multi-interface machines.

function getIPAddress() {
  var interfaces = require('os').networkInterfaces();
  for (var devName in interfaces) {
    var iface = interfaces[devName];

    for (var i = 0; i < iface.length; i++) {
      var alias = iface[i];
      if (alias.family === 'IPv4' && alias.address !== '127.0.0.1' && !alias.internal)
        return alias.address;
    }
  }
  return '0.0.0.0';
}

• process.cwd() returns directory where command has been executed (not directory of the node package) if it's has not been changed by 'process.chdir' inside of application.
• __filename returns absolute path to file where it is placed.
• __dirname returns absolute path to directory of __filename.

If you need to load files from your module directory you need to use relative paths.

require('../lib/test');

instead of

var lib  = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');

require(lib + '/test');

It's always relative to file where it called from and don't depend on current work dir.

If you use it more than once or in a loop, you could define a constant

public static final Foo[] FOO = new Foo[]{};

and do the conversion it like

Foo[] foos = fooCollection.toArray(FOO);

The toArray method will take the empty array to determine the correct type of the target array and create a new array for you.

Here's my proposal for the update:

Collection<Foo> foos = new ArrayList<Foo>();
Collection<Bar> temp = new ArrayList<Bar>();
for (Foo foo:foos) 
    temp.add(new Bar(foo));
Bar[] bars = temp.toArray(new Bar[]{});

Nobody mentioned it, but you can also simply use loc with the index and column labels.

df.loc[2, 'Letters']
# 'C'

Or, if you prefer to use "Numbers" column as reference, you can also set is as an index.

df.set_index('Numbers').loc[3, 'Letters']

Here's a small piece of code that I wrote, it resizes the image to fit the container while keeping the image's original aspect ratio. It takes in as parameters the container's width, height and the image. You can modify it to fit your needs. It's simple and works fine for my applications.

private Image scaleimage(int wid, int hei, BufferedImage img){
    Image im = img;
    double scale;
    double imw = img.getWidth();
    double imh = img.getHeight();
    if (wid > imw && hei > imh){
        im = img;
    }else if(wid/imw < hei/imh){
        scale = wid/imw;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    }else if (wid/imw > hei/imh){
        scale = hei/imh;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    }else if (wid/imw == hei/imh){
        scale = wid/imw;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    } 
    return im;
}

Let me first give you an implementation of unsophisticated nullptr_t

struct nullptr_t 
{
    void operator&() const = delete;  // Can't take address of nullptr

    template<class T>
    inline operator T*() const { return 0; }

    template<class C, class T>
    inline operator T C::*() const { return 0; }
};

nullptr_t nullptr;

nullptr is a subtle example of Return Type Resolver idiom to automatically deduce a null pointer of the correct type depending upon the type of the instance it is assigning to.

int *ptr = nullptr;                // OK
void (C::*method_ptr)() = nullptr; // OK

• As you can above, when nullptr is being assigned to an integer pointer, a int type instantiation of the templatized conversion function is created. And same goes for method pointers too.
• This way by leveraging template functionality, we are actually creating the appropriate type of null pointer every time we do, a new type assignment.
• As nullptr is an integer literal with value zero, you can not able to use its address which we accomplished by deleting & operator.

Why do we need nullptr in the first place?

• You see traditional NULL has some issue with it as below:

1?? Implicit conversion

char *str = NULL; // Implicit conversion from void * to char *
int i = NULL;     // OK, but `i` is not pointer type

2?? Function calling ambiguity

void func(int) {}
void func(int*){}
void func(bool){}

func(NULL);     // Which one to call?

• Compilation produces the following error:

error: call to 'func' is ambiguous
    func(NULL);
    ^~~~
note: candidate function void func(bool){}
                              ^
note: candidate function void func(int*){}
                              ^
note: candidate function void func(int){}
                              ^
1 error generated.
compiler exit status 1

3?? Constructor overload

struct String
{
    String(uint32_t)    {   /* size of string */    }
    String(const char*) {       /* string */        }
};

String s1( NULL );
String s2( 5 );

• In such cases, you need explicit cast (i.e., String s((char*)0)).

There is a way to do this, without resorting to the system call, you need to incorporate a wrapper something like this:

#include <sys/sendfile.h>
#include <fcntl.h>
#include <unistd.h>

/* 
** http://www.unixguide.net/unix/programming/2.5.shtml 
** About locking mechanism...
*/

int copy_file(const char *source, const char *dest){
   int fdSource = open(source, O_RDWR);

   /* Caf's comment about race condition... */
   if (fdSource > 0){
     if (lockf(fdSource, F_LOCK, 0) == -1) return 0; /* FAILURE */
   }else return 0; /* FAILURE */

   /* Now the fdSource is locked */

   int fdDest = open(dest, O_CREAT);
   off_t lCount;
   struct stat sourceStat;
   if (fdSource > 0 && fdDest > 0){
      if (!stat(source, &sourceStat)){
          int len = sendfile(fdDest, fdSource, &lCount, sourceStat.st_size);
          if (len > 0 && len == sourceStat.st_size){
               close(fdDest);
               close(fdSource);

               /* Sanity Check for Lock, if this is locked -1 is returned! */
               if (lockf(fdSource, F_TEST, 0) == 0){
                   if (lockf(fdSource, F_ULOCK, 0) == -1){
                      /* WHOOPS! WTF! FAILURE TO UNLOCK! */
                   }else{
                      return 1; /* Success */
                   }
               }else{
                   /* WHOOPS! WTF! TEST LOCK IS -1 WTF! */
                   return 0; /* FAILURE */
               }
          }
      }
   }
   return 0; /* Failure */
}

The above sample (error checking is omitted!) employs open, close and sendfile.

Edit: As caf has pointed out a race condition can occur between the open and stat so I thought I'd make this a bit more robust...Keep in mind that the locking mechanism varies from platform to platform...under Linux, this locking mechanism with lockf would suffice. If you want to make this portable, use the #ifdef macros to distinguish between different platforms/compilers...Thanks caf for spotting this...There is a link to a site that yielded "universal locking routines" here.

If you are at the root of your working directory, you can do git checkout -- . to check-out all files in the current HEAD and replace your local files.

You can also do git reset --hard to reset your working directory and replace all changes (including the index).

To create your custom log file, try this code

Mage::log('your debug message', null, 'yourlog_filename.log');

Perfectly good example in the Autocomplete docs with source code.

jQuery

<script>
  $(function() {
    function log( message ) {
      $( "<div>" ).text( message ).prependTo( "#log" );
      $( "#log" ).scrollTop( 0 );
    }

    $( "#city" ).autocomplete({
      source: function( request, response ) {
        $.ajax({
          url: "http://gd.geobytes.com/AutoCompleteCity",
          dataType: "jsonp",
          data: {
            q: request.term
          },
          success: function( data ) {
            response( data );
          }
        });
      },
      minLength: 3,
      select: function( event, ui ) {
        log( ui.item ?
          "Selected: " + ui.item.label :
          "Nothing selected, input was " + this.value);
      },
      open: function() {
        $( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
      },
      close: function() {
        $( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
      }
    });
  });
</script>

HTML

<div class="ui-widget">
  <label for="city">Your city: </label>
  <input id="city">
  Powered by <a href="http://geonames.org">geonames.org</a>

<div class="ui-widget" style="margin-top:2em; font-family:Arial">
  Result:
  <div id="log" style="height: 200px; width: 300px; overflow: auto;" class="ui-widget-content"></div>
</div>

Try this in your styles.xml:

colorPrimary will be the toolbar color.

<resources>

<style name="AppTheme" parent="Theme.AppCompat">
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_pressed</item>
    <item name="colorAccent">@color/accent</item>
</style>

Did you build this in Eclipse by the way?

Just think of what the words "child" and "descendant" mean in English:

• My daughter is both my child and my descendant
• My granddaughter is not my child, but she is my descendant.

If you're running PHP 5.3+ this will do the trick, place it at the topmost of your page:

if (get_magic_quotes_gpc() === 1)
{
    $_GET = json_decode(stripslashes(json_encode($_GET, JSON_HEX_APOS)), true);
    $_POST = json_decode(stripslashes(json_encode($_POST, JSON_HEX_APOS)), true);
    $_COOKIE = json_decode(stripslashes(json_encode($_COOKIE, JSON_HEX_APOS)), true);
    $_REQUEST = json_decode(stripslashes(json_encode($_REQUEST, JSON_HEX_APOS)), true);
}

Handles keys, values and multi-dimensional arrays.

I know this is an older question, but I wanted to post an answer for users with the same question:

curl -H 'Cache-Control: no-cache' http://www.example.com

This curl command servers in its header request to return non-cached data from the web server.

I found this much simpler. Simply type this into the terminal:

PATH=$PATH:C:\[pythondir]\scripts 

Just chain them together:

.a.b {
  color: #666;
}

If you want the last 5 rows, ordered in ascending order, you need a subquery:

SELECT *
FROM
    ( SELECT id, name, form_id, DATE(updated_at) AS updated_date, updated_at
      FROM wp_frm_items
      WHERE user_id = 11 
        AND form_id=9
      ORDER BY updated_at DESC
      LIMIT 5
    ) AS tmp
ORDER BY updated_at

After reading the question for 10th time, this may be (just maybe) what you want. Order by Date descending and then order by time (on same date) ascending:

SELECT id, name, form_id, DATE(updated_at) AS updated_date
FROM wp_frm_items
WHERE user_id = 11 
  AND form_id=9
ORDER BY DATE(updated_at) DESC
       , updated_at ASC

The "0x" counts towards the eight character count. You need "%#010x".

Note that # does not append the 0x to 0 - the result will be 0000000000 - so you probably actually should just use "0x%08x" anyway.

this answer is great I just want to comment on the last part of the answer

NOTE : You should have this stored in a PowerShell file and place that file at the root of your solution (where the .sln file resides), and then run it when you want a proper clean (not the micky mouse one that VisualStudio does, and reports success too).

Alternatively, you can add the following to your profile.ps1

function CleanSolution {
    Get-ChildItem -inc bin,obj -rec | Remove-Item -rec -force
}

Set-Alias cs CleanSolution 

Then you can use either CleanSolution or cs to run. That way you can use it for any project and without the ./ prefix of the filename

If you divide n elements into roughly k chunks you can make n % k chunks 1 element bigger than the other chunks to distribute the extra elements.

The following code will give you the length for the chunks:

[(n // k) + (1 if i < (n % k) else 0) for i in range(k)]

Example: n=11, k=3 results in [4, 4, 3]

You can then easily calculate the start indizes for the chunks:

[i * (n // k) + min(i, n % k) for i in range(k)]

Example: n=11, k=3 results in [0, 4, 8]

Using the i+1th chunk as the boundary we get that the ith chunk of list l with len n is

l[i * (n // k) + min(i, n % k):(i+1) * (n // k) + min(i+1, n % k)]

As a final step create a list from all the chunks using list comprehension:

[l[i * (n // k) + min(i, n % k):(i+1) * (n // k) + min(i+1, n % k)] for i in range(k)]

Example: n=11, k=3, l=range(n) results in [range(0, 4), range(4, 8), range(8, 11)]

with Apache PDFBox it goes like this:

PDDocument document = PDDocument.load(new File("test.pdf"));
if (!document.isEncrypted()) {
    PDFTextStripper stripper = new PDFTextStripper();
    String text = stripper.getText(document);
    System.out.println("Text:" + text);
}
document.close();

I too got the same problem
I downloaded get-pip.py from https://bootstrap.pypa.io/get-pip.py

and then ran python2.7 get-pip.py for installing pip2.7

and then ran the pip install command with python2.7 as follows

For Ubuntu/Linux:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

For Mac OS X:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

this should work just fine as it did for me :)

I followed these instructions from here

Others have given you the answer about appendChild.

Calling document.write() on a page that is not open (e.g. has finished loading) first calls document.open() which clears the entire content of the document (including the script calling document.write), so it's rarely a good idea to do that.

The top voted answer is deprecated in Bootstrap 3.3 and will be removed in v4. Try this instead:

JavaScript:

// Fill modal with content from link href
$("#myModal").on("show.bs.modal", function(e) {
    var link = $(e.relatedTarget);
    $(this).find(".modal-body").load(link.attr("href"));
});

Html (Based on the official example. Note that for Bootstrap 3.* we set data-remote="false" to disable the deprecated Bootstrap load function):

<!-- Link trigger modal -->
<a href="remoteContent.html" data-remote="false" data-toggle="modal" data-target="#myModal" class="btn btn-default">
    Launch Modal
</a>

<!-- Default bootstrap modal example -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>

In my case, I pushed several big (> 100Mb) files and then proceeded to remove them. But they were still in the history of my repo, so I had to remove them from it as well.

What did the trick was:

bfg -b 100M  # To remove all blobs from history, whose size is superior to 100Mb
git reflog expire --expire=now --all
git gc --prune=now --aggressive

Then, you need to push force on your branch:

git push origin <your_branch_name> --force

Note: bfg is a tool that can be installed on Linux and macOS using brew:

brew install bfg

Another way assuming it's not server side code you want to comment out is...

<asp:panel runat="server" visible="false">
    html here

For example string s="(U+007c)"

To remove only the parentheses from s, try the below one:

import re
a=re.sub("\\(","",s)
b=re.sub("\\)","",a)
print(b)

if (filePath != null) {
    File file = new File(filePath);
    Log.d("EDIT USER PROFILE", "UPLOAD: file length = " + file.length());
    Log.d("EDIT USER PROFILE", "UPLOAD: file exist = " + file.exists());

FINALLY POST DATA TO SERVER

httppost.setEntity(mpEntity);
HttpResponse response = httpclient.execute(httppost);

Two options:

• Install Oracle client on the PC you want to run your program on

• Use Oracle.ManagedDataAccess.dll

You can get it on NuGet (search 'oracle managed') or download ODP.NET_Managed.zip (link is to a beta version, but points you in the right direction)

I use this so that the computers I deploy onto don't need Oracle client installed.

N.B. in my opinion this is good for console apps but annoying if you intend to install your application, so I install the client in that case.

You can add the following registry key:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\myexe.exe

In this key, add the default string value containing the path to the exe file.

It is impossible to safely escape a string without a DB connection. mysql_real_escape_string() and prepared statements need a connection to the database so that they can escape the string using the appropriate character set - otherwise SQL injection attacks are still possible using multi-byte characters.

If you are only testing, then you may as well use mysql_escape_string(), it's not 100% guaranteed against SQL injection attacks, but it's impossible to build anything safer without a DB connection.

Source: Use NATURAL FULL JOIN to compare two tables in SQL by Lukas Eder

Clever approach of using NATURAL FULL JOIN to detect the same/different rows between two tables.

Example 1 - status flag:

SELECT t1.*, t2.*, CASE WHEN t1 IS NULL OR t2 IS NULL THEN 'Not equal' ELSE 'Equal' END
FROM t1
NATURAL FULL JOIN t2;

Example 2 - filtering rows

SELECT *
FROM (SELECT 't1' AS t1, t1.* FROM t1) t1 
NATURAL FULL JOIN (SELECT 't2' AS t2, t2.* FROM t2) t2 
WHERE t1 IS NULL OR t2 IS NULL -- show differences
--WHERE  t1 IS NOT NULL AND t2 IS NOT NULL    -- show the same

I had a similar problem after cloning AnySoftKeyboard and opening it in Android Studio. What worked for me was deleting the AynSoftKeyboard/gradle folder and then cleaning the project via menu item Build > Clean Project.

So try deleting YourProject/gradle folder and clean the project to trigger a Gradle sync.

Hope it works for your case.

Group By X means put all those with the same value for X in the one group.

Group By X, Y means put all those with the same values for both X and Y in the one group.

To illustrate using an example, let's say we have the following table, to do with who is attending what subject at a university:

Table: Subject_Selection

+---------+----------+----------+
| Subject | Semester | Attendee |
+---------+----------+----------+
| ITB001  |        1 | John     |
| ITB001  |        1 | Bob      |
| ITB001  |        1 | Mickey   |
| ITB001  |        2 | Jenny    |
| ITB001  |        2 | James    |
| MKB114  |        1 | John     |
| MKB114  |        1 | Erica    |
+---------+----------+----------+

When you use a group by on the subject column only; say:

select Subject, Count(*)
from Subject_Selection
group by Subject

You will get something like:

+---------+-------+
| Subject | Count |
+---------+-------+
| ITB001  |     5 |
| MKB114  |     2 |
+---------+-------+

...because there are 5 entries for ITB001, and 2 for MKB114

If we were to group by two columns:

select Subject, Semester, Count(*)
from Subject_Selection
group by Subject, Semester

we would get this:

+---------+----------+-------+
| Subject | Semester | Count |
+---------+----------+-------+
| ITB001  |        1 |     3 |
| ITB001  |        2 |     2 |
| MKB114  |        1 |     2 |
+---------+----------+-------+

This is because, when we group by two columns, it is saying "Group them so that all of those with the same Subject and Semester are in the same group, and then calculate all the aggregate functions (Count, Sum, Average, etc.) for each of those groups". In this example, this is demonstrated by the fact that, when we count them, there are three people doing ITB001 in semester 1, and two doing it in semester 2. Both of the people doing MKB114 are in semester 1, so there is no row for semester 2 (no data fits into the group "MKB114, Semester 2")

Hopefully that makes sense.

I would suggest to use he style approach in android as the way to configure built-in android views, add new style in your project:

<style name="yourStyle" parent="Base.Theme.AppCompat">
    <item name="colorAccent">your_color</item> <!-- for uncheck state -->
    <item name="android:textColorSecondary">your color</item> <!-- for check state -->
</style>

and add assign this style to the theme of the checkbox: android:theme="@style/youStyle"

hope this helps.

Use ng-switch with expression and ng-switch-when for matching expression value:

<div ng-switch="data.id">
  <div ng-switch-when="5">...</div>
  <div ng-switch-default>...</div>
</div>

Example is here

Angular2 example

Yet another approach is ISNULL().

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = ISNULL(@ABC, [ABC]),
    [ABCD] = ISNULL(@ABCD, [ABCD])

The difference between ISNULL and COALESCE is the return type. COALESCE can also take more than 2 arguments, and use the first that is not null. I.e.

select COALESCE(null, null, 1, 'two') --returns 1
select COALESCE(null, null, null, 'two') --returns 'two'

In contribution to ellabeauty's answer. you can also use this dynamic percentage values

$('.bar').css('width',  function(){ return ($(this).attr('data-percentage')+'%')});

And probably add custom easing to your css

.bar {
 -webkit-transition: width 2.50s ease !important;
 -moz-transition: width 2.50s ease !important;
   -o-transition: width 2.50s ease !important;
      transition: width 2.50s ease !important;
 }

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

I had the same problem and I ended up finding out that this seems to be a known bug in DALI (Eclipse Java Persistence Tools) since at least eclipse 3.8 which could cause the save action in the java editor to be extremly slow.

Since this hasn't been fully resolved in Kepler (20130614-0229) yet and because I don't need JPT/DALI in my eclipse I ended up manually removing the org.eclipse.jpt features and plugins.

What I did was:

1.) exit eclipse

2.) go to my eclipse install directory

cd eclipse

and execute these steps:

*nix:

mkdir disabled
mkdir disabled/features disabled/plugins

mv plugins/org.eclipse.jpt.* disabled/plugins
mv features/org.eclipse.jpt.* disabled/features

windows:

mkdir disabled
mkdir disabled\features 
mkdir disabled\plugins

move plugins\org.eclipse.jpt.* disabled\plugins
for /D /R %D in (features\org.eclipse.jpt.*) do move %D disabled\features

3.) Restart eclipse.

After startup and on first use eclipse may warn you that you need to reconfigure your content-assist. Do this in your preferences dialog.

Done.

After uninstalling DALI/JPT my eclipse feels good again. No more blocked UI and waiting for seconds when saving a file.

For someone who is new to IPC and Named Pipes, I found the following NuGet package to be a great help.

GitHub: Named Pipe Wrapper for .NET 4.0

To use first install the package:

PS> Install-Package NamedPipeWrapper

Then an example server (copied from the link):

var server = new NamedPipeServer<SomeClass>("MyServerPipe");
server.ClientConnected += delegate(NamedPipeConnection<SomeClass> conn)
    {
        Console.WriteLine("Client {0} is now connected!", conn.Id);
        conn.PushMessage(new SomeClass { Text: "Welcome!" });
    };

server.ClientMessage += delegate(NamedPipeConnection<SomeClass> conn, SomeClass message)
    {
        Console.WriteLine("Client {0} says: {1}", conn.Id, message.Text);
    };

server.Start();

Example client:

var client = new NamedPipeClient<SomeClass>("MyServerPipe");
client.ServerMessage += delegate(NamedPipeConnection<SomeClass> conn, SomeClass message)
    {
        Console.WriteLine("Server says: {0}", message.Text);
    };

client.Start();

Best thing about it for me is that unlike the accepted answer here it supports multiple clients talking to a single server.

There is a package random_word could implement this request very conveniently:

 $ pip install random-word

from random_word import RandomWords
r = RandomWords()

# Return a single random word
r.get_random_word()
# Return list of Random words
r.get_random_words()
# Return Word of the day
r.word_of_the_day()

In addition to using the master method (or one of its specializations), I test my algorithms experimentally. This can't prove that any particular complexity class is achieved, but it can provide reassurance that the mathematical analysis is appropriate. To help with this reassurance, I use code coverage tools in conjunction with my experiments, to ensure that I'm exercising all the cases.

As a very simple example say you wanted to do a sanity check on the speed of the .NET framework's list sort. You could write something like the following, then analyze the results in Excel to make sure they did not exceed an n*log(n) curve.

In this example I measure the number of comparisons, but it's also prudent to examine the actual time required for each sample size. However then you must be even more careful that you are just measuring the algorithm and not including artifacts from your test infrastructure.

int nCmp = 0;
System.Random rnd = new System.Random();

// measure the time required to sort a list of n integers
void DoTest(int n)
{
   List<int> lst = new List<int>(n);
   for( int i=0; i<n; i++ )
      lst[i] = rnd.Next(0,1000);

   // as we sort, keep track of the number of comparisons performed!
   nCmp = 0;
   lst.Sort( delegate( int a, int b ) { nCmp++; return (a<b)?-1:((a>b)?1:0)); }

   System.Console.Writeline( "{0},{1}", n, nCmp );
}


// Perform measurement for a variety of sample sizes.
// It would be prudent to check multiple random samples of each size, but this is OK for a quick sanity check
for( int n = 0; n<1000; n++ )
   DoTest(n);

There is no native Now() function in SQL Server so you should use:

select GETDATE() --2012-05-01 10:14:13.403

you can get day, month and year separately by doing:

select DAY(getdate())  --1
select month(getdate())  --5
select year(getdate()) --2012

if you are on sql server 2008, there is the DATE date time which has only the date part, not the time:

select cast (GETDATE() as DATE) --2012-05-01

Use "&" instead of "&".

For Angular 7

Check where is your table component located. In my case it was located like app/shared/tablecomponent where shared folder contains all sub components But I was importing material module in Ngmodules of app.module.ts which was incorrect. In this case Material module should be imported in Ngmodules of shared.module.ts And it works.

There is NO NEED to change 'table' to 'mat-table' in angular 7.

Angular7 - Can't bind to 'dataSource' since it isn't a known property of 'mat-table'

No need to stash.

git checkout -b new_branch_name

does not touch your local changes. It just creates the branch from the current HEAD and sets the HEAD there. So I guess that's what you want.

--- Edit to explain the result of checkout master ---

Are you confused because checkout master does not discard your changes?

Since the changes are only local, git does not want you to lose them too easily. Upon changing branch, git does not overwrite your local changes. The result of your checkout master is:

M   testing

, which means that your working files are not clean. git did change the HEAD, but did not overwrite your local files. That is why your last status still show your local changes, although you are on master.

If you really want to discard the local changes, you have to force the checkout with -f.

git checkout master -f

Since your changes were never committed, you'd lose them.

Try to get back to your branch, commit your changes, then checkout the master again.

git checkout new_branch
git commit -a -m"edited"
git checkout master
git status

You should get a M message after the first checkout, but then not anymore after the checkout master, and git status should show no modified files.

--- Edit to clear up confusion about working directory (local files)---

In answer to your first comment, local changes are just... well, local. Git does not save them automatically, you must tell it to save them for later. If you make changes and do not explicitly commit or stash them, git will not version them. If you change HEAD (checkout master), the local changes are not overwritten since unsaved.

std::copy does the job as far as moving elements is concerned:

 #include <algorithm>

 std::copy(array+3, array+5, array+2);

Note that the precondition for copy is that the destination must not be in the source range. It's permissible for the ranges to overlap.

Also, because of the way arrays work in C++, this doesn't "shorten" the array. It just shifts elements around within it. There is no way to change the size of an array, but if you're using a separate integer to track its "size" meaning the size of the part you care about, then you can of course decrement that.

So, the array you'll end up with will be as if it were initialized with:

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

you can also use:

SELECT CASE
         WHEN upper(t.name) like 'P%' THEN
          'productive'
         WHEN upper(t.name) like 'T%' THEN
          'test'
         WHEN upper(t.name) like 'D%' THEN
          'development'
         ELSE
          'unknown'
       END as type
FROM table t

Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.

In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:

CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
  one int;
  two int;
BEGIN
  one := 1;
  two := 2;
  RETURN one + two;
END
$$;
SELECT somefuncname();

The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.

My version of the accepted answer as a function using DATEPART, so I don't have to do a string comparison on the line with

DATENAME(dw, @StartDate) = 'Sunday'

Anyway, here's my business datediff function

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE FUNCTION BDATEDIFF
(
    @startdate as DATETIME,
    @enddate as DATETIME
)
RETURNS INT
AS
BEGIN
    DECLARE @res int

SET @res = (DATEDIFF(dd, @startdate, @enddate) + 1)
    -(DATEDIFF(wk, @startdate, @enddate) * 2)
    -(CASE WHEN DATEPART(dw, @startdate) = 1 THEN 1 ELSE 0 END)
    -(CASE WHEN DATEPART(dw, @enddate) = 7 THEN 1 ELSE 0 END)

    RETURN @res
END
GO

Basic difference between getAttribute() and getParameter() is the return type.

java.lang.Object getAttribute(java.lang.String name)
java.lang.String getParameter(java.lang.String name)

One way is using the immediate selector and negative margin. This rule will select a list right after a paragraph, so it's just setting a negative margin-top.

p + ul {  
   margin-top: -XX;
}

With .Net Core it is now very easy:

I had a java.lang.reflect.InvocationTargetException error from a statement calling a logger object in an external class inside a try / catch block in my class.

mysqld --help --verbose will find only location of default configuration file. What if you use 2 MySQL instances on the same server? It's not going to help.

Good article about figuring it out:

"How to find MySQL configuration file?"

One option is you can wrap it into another array:

Foo(new object[]{ new object[]{ (object)"1", (object)"2" } });

Kind of ugly, but since each item is an array, you can't just cast it to make the problem go away... such as if it were Foo(params object items), then you could just do:

Foo((object) new object[]{ (object)"1", (object)"2" });

Alternatively, you could try defining another overloaded instance of Foo which takes just a single array:

void Foo(object[] item)
{
    // Somehow don't duplicate Foo(object[]) and
    // Foo(params object[]) without making an infinite
    // recursive call... maybe something like
    // FooImpl(params object[] items) and then this
    // could invoke it via:
    // FooImpl(new object[] { item });
}

The accepted answer is not complete without the remainder of instructions (paraphrased below) from the forum thread linked to:

Curry can simplify your code. This is one of the main reasons to use this. Currying is a process of converting a function that accepts n arguments into n functions that accept only one argument.

The principle is to pass the arguments of the passed function, using the closure (closure) property, to store them in another function and treat it as a return value, and these functions form a chain, and the final arguments are passed in to complete the operation.

The benefit of this is that it can simplify the processing of parameters by dealing with one parameter at a time, which can also improve the flexibility and readability of the program. This also makes the program more manageable. Also dividing the code into smaller pieces would make it reuse-friendly.

For example:

function curryMinus(x) 
{
  return function(y) 
  {
    return x - y;
  }
}

var minus5 = curryMinus(1);
minus5(3);
minus5(5);

I can also do...

var minus7 = curryMinus(7);
minus7(3);
minus7(5);

This is very great for making complex code neat and handling of unsynchronized methods etc.

I know my case is rare, but I'll still add it here for someone who troubleshoots it later. I had a Linux Kernel module target in my Makefile and I tried to compile my user space program together with the kernel module that doesn't have stdio. Making it a separate target solved the problem.

Idea 8.0 has the lovely ctrl+shift+space x 2 that does the following autocomplete:

 City city = customer.<ctrl-shift-space twice>

resolves to

 City city = customer.getAddress().getCity();

through any number of levels of getters/setters.

This can do the trick,

function createLog($data){ 
    $file = "Your path/incompletejobs.txt";
    $fh = fopen($file, 'a') or die("can't open file");
    fwrite($fh,$data);
    fclose($fh);
}
$qry="INSERT INTO redirects SET ua_string = '$ua_string'"   
$result=mysql_query($qry);
if(!$result){
    createLog(mysql_error());
}

chmod 400 /etc/ssh/* works for me.

To schedule the update to be automatic you should:

• Go to Control Panel » Administrative Tools » Scheduled Tasks
• Create the (basic) task
• Go to Schedule » Advanced
• Check the box for "Repeat Task" every 10 minutes with a duration of, e.g. 24 hours or Indefinitely
• Leave End Date unchecked

If you cannot find the Schedule settings, look under: Properties, Edit, Triggers.

Wrap them around a div with the following CSS

.div_wrapper{

Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.

To get the string representation using at least 4 digits:

int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"

In Python2,

d1={'a':1,'b':2}
d2={'a':10,'c':3}

d1 overrides d2:

dict(d2,**d1)
# {'a': 1, 'c': 3, 'b': 2}

d2 overrides d1:

dict(d1,**d2)
# {'a': 10, 'c': 3, 'b': 2}

This behavior is not just a fluke of implementation; it is guaranteed in the documentation:

If a key is specified both in the positional argument and as a keyword argument, the value associated with the keyword is retained in the dictionary.

"/(http(s?):\/\/)([a-z0-9\-]+\.)+[a-z]{2,4}(\.[a-z]{2,4})*(\/[^ ]+)*/i"

1. (http(s?)://) means http:// or https://

2. ([a-z0-9-]+.)+ => 2.0[a-z0-9-] means any a-z character or any 0-9 or (-)sign)

                2.1 (+) means the character can be one or more ex: a1w, 
                    a9-,c559s, f)
   
                2.2 \. is (.)sign
   
                2.3. the (+) sign after ([a-z0-9\-]+\.) mean do 2.1,2.2,2.3 
                   at least 1 time 
                 ex: abc.defgh0.ig, aa.b.ced.f.gh. also in case www.yyy.com
   
                3.[a-z]{2,4} mean a-z at least 2 character but not more than 
                             4 characters for check that there will not be 
                             the case 
                             ex: https://www.google.co.kr.asdsdagfsdfsf
   
                4.(\.[a-z]{2,4})*(\/[^ ]+)* mean 
   
                  4.1 \.[a-z]{2,4} means like number 3 but start with 
                      (.)sign 
   
                  4.2 * means (\.[a-z]{2,4})can be use or not use never mind
   
                  4.3 \/ means \
                  4.4 [^ ] means any character except blank
                  4.5 (+) means do 4.3,4.4,4.5 at least 1 times
                  4.6 (*) after (\/[^ ]+) mean use 4.3 - 4.5 or not use 
                      no problem
   
                  use for case https://stackoverflow.com/posts/51441301/edit
   
                  5. when you use regex write in "/ /" so it come
   

   "/(http(s?)://)([a-z0-9-]+.)+[a-z]{2,4}(.[a-z]{2,4})(/[^ ]+)/i"

                  6. almost forgot: letter i on the back mean ignore case of 
                     Big letter or small letter ex: A same as a, SoRRy same 
                     as sorry.
   

Note : Sorry for bad English. My country not use it well.

I just had the same issue with Font Awesome. Turned out this was caused by a problem with FTP. The file was uploaded as text (ASCII) instead of binary, which corrupted the file. I simply changed my FTP software to binary, re-uploaded the font files, and then it all worked.

https://css-tricks.com/forums/topic/custom-fonts-returns-failed-to-decode-downloaded-font/ this helped me in the end I had the same issue with FTP transferring files as text

After coming back to my own question after 5 year and seeing so many people found this useful, a little update.

A string variable can be split into a list by using the split function (it can contain similar values, set is for the assignment) . I haven't found this function in the official documentation but it works similar to normal Python. The items can be called via an index, used in a loop or like Dave suggested if you know the values, it can set variables like a tuple.

{% set list1 = variable1.split(';') %}
The grass is {{ list1[0] }} and the boat is {{ list1[1] }}

or

{% set list1 = variable1.split(';') %}
{% for item in list1 %}
    <p>{{ item }}<p/>
{% endfor %} 

or

{% set item1, item2 = variable1.split(';') %}
The grass is {{ item1 }} and the boat is {{ item2 }}

Declaration

Declaration, generally, refers to the introduction of a new name in the program. For example, you can declare a new function by describing it's "signature":

void xyz();

or declare an incomplete type:

class klass;
struct ztruct;

and last but not least, to declare an object:

int x;

It is described, in the C++ standard, at §3.1/1 as:

A declaration (Clause 7) may introduce one or more names into a translation unit or redeclare names introduced by previous declarations.

Definition

A definition is a definition of a previously declared name (or it can be both definition and declaration). For example:

int x;
void xyz() {...}
class klass {...};
struct ztruct {...};
enum { x, y, z };

Specifically the C++ standard defines it, at §3.1/1, as:

A declaration is a definition unless it declares a function without specifying the function’s body (8.4), it contains the extern specifier (7.1.1) or a linkage-specification25 (7.5) and neither an initializer nor a function- body, it declares a static data member in a class definition (9.2, 9.4), it is a class name declaration (9.1), it is an opaque-enum-declaration (7.2), it is a template-parameter (14.1), it is a parameter-declaration (8.3.5) in a function declarator that is not the declarator of a function-definition, or it is a typedef declaration (7.1.3), an alias-declaration (7.1.3), a using-declaration (7.3.3), a static_assert-declaration (Clause 7), an attribute- declaration (Clause 7), an empty-declaration (Clause 7), or a using-directive (7.3.4).

Initialization

Initialization refers to the "assignment" of a value, at construction time. For a generic object of type T, it's often in the form:

T x = i;

but in C++ it can be:

T x(i);

or even:

T x {i};

with C++11.

Conclusion

So does it mean definition equals declaration plus initialization?

It depends. On what you are talking about. If you are talking about an object, for example:

int x;

This is a definition without initialization. The following, instead, is a definition with initialization:

int x = 0;

In certain context, it doesn't make sense to talk about "initialization", "definition" and "declaration". If you are talking about a function, for example, initialization does not mean much.

So, the answer is no: definition does not automatically mean declaration plus initialization.

I was also looking to list repositories in SVN. I did something like this on shell prompt:

We actually have some notification code in our product that uses TLS to send mail if it is available.

You will need to set the Java Mail properties. You only need the TLS one but you might need SSL if your SMTP server uses SSL.

Properties props = new Properties();
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");  // If you need to authenticate
// Use the following if you need SSL
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

You can then either pass this to a JavaMail Session or any other session instantiator like Session.getDefaultInstance(props).

I created .pfx file from .key and .pem files.

Like this openssl pkcs12 -inkey rootCA.key -in rootCA.pem -export -out rootCA.pfx

That's not the direct answer but still maybe it helps out someone else.

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

This is the simplest way to loop through a form accessing only the form elements. Inside the each function you can check and build whatever you want. When building objects note that you will want to declare it outside of the each function.

EDIT JSFIDDLE

The below will work

$('form[name=formName]').find('input, textarea, select').each(function() {
    alert($(this).attr('name'));
});

If the data is a static or global variable, it is zero-filled by default, so just declare it myStruct _m;

If the data is a local variable or a heap-allocated zone, clear it with memset like:

memset(&m, 0, sizeof(myStruct));

Current compilers (e.g. recent versions of gcc) optimize that quite well in practice. This works only if all zero values (include null pointers and floating point zero) are represented as all zero bits, which is true on all platforms I know about (but the C standard permits implementations where this is false; I know no such implementation).

You could perhaps code myStruct m = {}; or myStruct m = {0}; (even if the first member of myStruct is not a scalar).

My feeling is that using memset for local structures is the best, and it conveys better the fact that at runtime, something has to be done (while usually, global and static data can be understood as initialized at compile time, without any cost at runtime).

You can use the JDOM library in Java. Define your tags as Element objects, document your elements with Document Class, and build your xml file with SAXBuilder. Try this example:

//Root Element
Element root=new Element("CONFIGURATION");
Document doc=new Document();
//Element 1
Element child1=new Element("BROWSER");
//Element 1 Content
child1.addContent("chrome");
//Element 2
Element child2=new Element("BASE");
//Element 2 Content
child2.addContent("http:fut");
//Element 3
Element child3=new Element("EMPLOYEE");
//Element 3 --> In this case this element has another element with Content
child3.addContent(new Element("EMP_NAME").addContent("Anhorn, Irene"));

//Add it in the root Element
root.addContent(child1);
root.addContent(child2);
root.addContent(child3);
//Define root element like root
doc.setRootElement(root);
//Create the XML
XMLOutputter outter=new XMLOutputter();
outter.setFormat(Format.getPrettyFormat());
outter.output(doc, new FileWriter(new File("myxml.xml")));

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.

On Mac, the Android SDK gets installed at: /Users/username/Library/Android/sdk/, therefore, you will need to run the script as sudo, as follows:

sudo sh /Users/username/Library/Android/sdk/extras/intel/Hardware_Accelerated_Execution_Manager/silent_install.sh

If all goes well, the script prints the message: "Silent installation Pass!"

Then, restart Android Studio and run your app with the desired AVD.

a late answer, but I think this one works as required in the question :)

this one uses z-index and position absolute, and avoid the issue that the container element width doesn't grow in transition.

You can tweak the text's margin and padding to suit your needs, and "+" can be changed to font awesome icons if needed.

body {
  font-size: 16px;
}

.container {
  height: 2.5rem;
  position: relative;
  width: auto;
  display: inline-flex;
  align-items: center;
}

.add {
  font-size: 1.5rem;
  color: #fff;
  cursor: pointer;
  font-size: 1.5rem;
  background: #2794A5;
  border-radius: 20px;
  height: 100%;
  width: 2.5rem;
  display: flex;
  justify-content: center;
  align-items: center;
  position: absolute;
  z-index: 2;
}

.text {
  white-space: nowrap;
  position: relative;
  z-index: 1;
  height: 100%;
  width: 0;
  color: #fff;
  overflow: hidden;
  transition: 0.3s all ease;
  background: #2794A5;
  height: 100%;
  display: flex;
  align-items: center;
  border-top-right-radius: 20px;
  border-bottom-right-radius: 20px;
  margin-left: 20px;
  padding-left: 20px;
  cursor: pointer;
}

.container:hover .text {
  width: 100%;
  padding-right: 20px;
}

<div class="container">
  <span class="add">+</span>
  <span class="text">Add new client</span>
</div>

If you know the type of image and only want to generate a file, there's no need to get a BufferedImage instance. Just write the bytes to a file with the correct extension.

try (OutputStream out = new BufferedOutputStream(new FileOutputStream(path))) {
    out.write(bytes);
}

lambda is an anonymous function, it is equivalent to:

def func(p):
   return p.totalScore     

Now max becomes:

max(players, key=func)

But as def statements are compound statements they can't be used where an expression is required, that's why sometimes lambda's are used.

Note that lambda is equivalent to what you'd put in a return statement of a def. Thus, you can't use statements inside a lambda, only expressions are allowed.

What does max do?

max(a, b, c, ...[, key=func]) -> value

With a single iterable argument, return its largest item. With two or more arguments, return the largest argument.

So, it simply returns the object that is the largest.

How does key work?

By default in Python 2 key compares items based on a set of rules based on the type of the objects (for example a string is always greater than an integer).

To modify the object before comparison, or to compare based on a particular attribute/index, you've to use the key argument.

Example 1:

A simple example, suppose you have a list of numbers in string form, but you want to compare those items by their integer value.

>>> lis = ['1', '100', '111', '2']

Here max compares the items using their original values (strings are compared lexicographically so you'd get '2' as output) :

>>> max(lis)
'2'

To compare the items by their integer value use key with a simple lambda:

>>> max(lis, key=lambda x:int(x))  # compare `int` version of each item
'111'

Example 2: Applying max to a list of tuples.

>>> lis = [(1,'a'), (3,'c'), (4,'e'), (-1,'z')]

By default max will compare the items by the first index. If the first index is the same then it'll compare the second index. As in my example, all items have a unique first index, so you'd get this as the answer:

>>> max(lis)
(4, 'e')

But, what if you wanted to compare each item by the value at index 1? Simple: use lambda:

>>> max(lis, key = lambda x: x[1])
(-1, 'z')

Comparing items in an iterable that contains objects of different type:

List with mixed items:

lis = ['1','100','111','2', 2, 2.57]

In Python 2 it is possible to compare items of two different types:

>>> max(lis)  # works in Python 2
'2'
>>> max(lis, key=lambda x: int(x))  # compare integer version of each item
'111'

But in Python 3 you can't do that any more:

>>> lis = ['1', '100', '111', '2', 2, 2.57]
>>> max(lis)
Traceback (most recent call last):
  File "<ipython-input-2-0ce0a02693e4>", line 1, in <module>
    max(lis)
TypeError: unorderable types: int() > str()

But this works, as we are comparing integer version of each object:

>>> max(lis, key=lambda x: int(x))  # or simply `max(lis, key=int)`
'111'

You can also use this code to get LayoutInflater:

LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)

I tried closing a modal window with a bootstrap CSS loaded. The close () method does not really close the modal window. So I added the display style to "none".

    function closeDialog() {
        let d = document.getElementById('d')
        d.style.display = "none"
        d.close()
    }

The HTML code includes a button into the dialog window.

<input type="submit" value="Confirm" onclick="closeDialog()"/>

I guess this can help :

selection styles

It's possible to define color and background for text the user selects.

Try it below. If you select something and it looks like this, your browser supports selection styles.

This is the paragraph with normal ::selection.

This is the paragraph with ::-moz-selection.

This is the paragraph with ::-webkit-selection.

Testsheet:

p.normal::selection {
  background:#cc0000;
  color:#fff;
}

p.moz::-moz-selection {
  background:#cc0000;
  color:#fff;
}

p.webkit::-webkit-selection {
  background:#cc0000;
  color:#fff;
}

Quoted from Quirksmode

On what basis should the merging take place? Your question is rather vague. Also, I assume a, b, ..., f are supposed to be strings, that is, 'a', 'b', ..., 'f'.

>>> x = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
>>> x[3:6] = [''.join(x[3:6])]
>>> x
['a', 'b', 'c', 'def', 'g']

Check out the documentation on sequence types, specifically on mutable sequence types. And perhaps also on string methods.

DAO (Data Access Object) is a very used design pattern in enterprise applications. It basically is the module that is used to access data from every source (DBMS, XML and so on). I suggest you to read some examples, like this one:

DAO Example

Please note that there are different ways to implements the original DAO Pattern, and there are many frameworks that can simplify your work. For example, the ORM (Object Relational Mapping) frameworks like iBatis or Hibernate, are used to map the result of SQL queries to java objects.

Hope it helps, Bye!

Just delete the Github repo and create a new one. By far the fastest, easiest and safest approach. After all, what do you have to gain carrying out all those commands in the accepted solution when all you want is the master branch with a single commit?

In your View try like this

  <img src= "@Url.Content(Model.ImagePath)" alt="Image" />

Working example:

    Intent intent = new Intent(ctx, HomeActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder b = new NotificationCompat.Builder(ctx);

    b.setAutoCancel(true)
     .setDefaults(Notification.DEFAULT_ALL)
     .setWhen(System.currentTimeMillis())         
     .setSmallIcon(R.drawable.ic_launcher)
     .setTicker("Hearty365")            
     .setContentTitle("Default notification")
     .setContentText("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
     .setDefaults(Notification.DEFAULT_LIGHTS| Notification.DEFAULT_SOUND)
     .setContentIntent(contentIntent)
     .setContentInfo("Info");


    NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(1, b.build());

You can look up the constraint name in the sys.key_constraints table:

SELECT name
FROM   sys.key_constraints
WHERE  [type] = 'PK'
       AND [parent_object_id] = Object_id('dbo.Student');

If you don't care about the name, but simply want to drop it, you can use a combination of this and dynamic sql:

DECLARE @table NVARCHAR(512), @sql NVARCHAR(MAX);

SELECT @table = N'dbo.Student';

SELECT @sql = 'ALTER TABLE ' + @table 
    + ' DROP CONSTRAINT ' + name + ';'
    FROM sys.key_constraints
    WHERE [type] = 'PK'
    AND [parent_object_id] = OBJECT_ID(@table);

EXEC sp_executeSQL @sql;

This code is from Aaron Bertrand (source).

If you mark a form element as required="" then novalidate="" does not help.

A way to circumvent the required validation is to disable the element.

Actually, there is a way to set global defaults for Sun's JVM via environment variables.

See How to set a java system property so that it is effective whenever I start JVM without adding it to the command line arguments.

When you set a string variable, it doesn't save quotes of it, they are a part of its definition. so you don't need to use :1

I had the same requirement - I just use this. User enters the number of days by which he/she wants to limit the calendar range to.

  SELECT DAY, offset
    FROM (SELECT to_char(SYSDATE, 'DD-MON-YYYY') AS DAY, 0 AS offset
            FROM DUAL
          UNION ALL
          SELECT to_char(SYSDATE - rownum, 'DD-MON-YYYY'), rownum
            FROM all_objects d)
            where offset <= &No_of_days

I use the above result set as driving view in LEFT OUTER JOIN with other views involving tables which have dates.

Network communication Host -> Guest

Connect to the Guest and find out the ip address:

ifconfig 

example of result (ip address is 10.0.2.15):

eth0      Link encap:Ethernet  HWaddr 08:00:27:AE:36:99
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

Go to Vbox instance window -> Menu -> Network adapters:

• adapter should be NAT
• click on "port forwarding"
• insert new record (+ icon)
  • for host ip enter 127.0.0.1, and for guest ip address you got from prev. step (in my case it is 10.0.2.15)
  • in your case port is 8000 - put it on both, but you can change host port if you prefer

Go to host system and try it in browser:

http://127.0.0.1:8000

or your network ip address (find out on the host machine by running: ipconfig).

Network communication Guest -> Host

In this case port forwarding is not needed, the communication goes over the LAN back to the host.

On the host machine - find out your netw ip address:

ipconfig

example of result:

IP Address. . . . . . . . . . . . : 192.168.5.1

On the guest machine you can communicate directly with the host, e.g. check it with ping:

# ping 192.168.5.1
PING 192.168.5.1 (192.168.5.1) 56(84) bytes of data.
64 bytes from 192.168.5.1: icmp_seq=1 ttl=128 time=2.30 ms
...

Firewall issues?

@Stranger suggested that in some cases it would be necessary to open used port (8000 or whichever is used) in firewall like this (example for ufw firewall, I haven't tested):

sudo ufw allow 8000 

One of the benefits is that Razor views can be rendered inside unit tests, this is something that was not easily possible with the previous ASP.Net renderer.

From ScottGu's announcement this is listed as one of the design goals:

Unit Testable: The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server, and can be hosted in any unit test project – no special app-domain required).

From This page, the container dies after running everything correctly but crashes because all the commands ended. Either you make your services run on the foreground, or you create a keep alive script. By doing so, Kubernetes will show that your application is running. We have to note that in the Docker environment, this problem is not encountered. It is only Kubernetes that wants a running app.

Update (an example):

Here's how to avoid CrashLoopBackOff, when launching a Netshoot container:

kubectl run netshoot --image nicolaka/netshoot -- sleep infinity

Maybe you are using:

$(document).ready(function(){
   // Your code here
 });

Try this instead:

window.onload = function(){  }

Try to set the element's value using the executeScript method of JavascriptExecutor:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.getElementById('elementID').setAttribute('value', 'new value for element')");

A combination of solutions worked for me. I tried to kill and restart explorer.exe as suggested by @LeighRiffel. Did not work. I uninstalled dropbox because I rarely use it. Then, I tried the explorer thing again and it worked. Maybe you can reinstall dropbox after this and see if things are okay ? I don't care though.

Here are the steps: Run taskmgr.exe or task manager > processes tab > select explorer.exe > kill. Then click file option > new task > enter explorer.exe > ok.

I wrote a simple script that test the speed and this is what I found out. Actually for loop was fastest in my case. That really suprised me, check out bellow (was calculating sum of squares).

from functools import reduce

def time_it(func, numbers, *args):
    start_t = datetime.datetime.now()
    for i in range(numbers):
        func(args[0])
    print (datetime.datetime.now()-start_t)

def square_sum1(numbers):
    return reduce(lambda sum, next: sum+next**2, numbers, 0)


def square_sum2(numbers):
    a = 0
    for i in numbers:
        i = i**2
        a += i
    return a

def square_sum3(numbers):
    sqrt = lambda x: x**2
    return sum(map(sqrt, numbers))
