Easily! (because someone else already did the work for us...)

After spending a lot of time trying to this with the suggested answers I came across this codeplex project Windows Input Simulator which made it simple as can be to simulate a key press:

1. Install the package, can be done or from the NuGet package manager or from the package manager console like:

   Install-Package InputSimulator

2. Use this 2 lines of code:

   inputSimulator = new InputSimulator() inputSimulator.Keyboard.KeyDown(VirtualKeyCode.RETURN)

And that's it!

-------EDIT--------

The project page on codeplex is flagged for some reason, this is the link to the NuGet gallery.

$('.ui-icon-circle-triangle-w').text('<<');

Not possible with standard unix commands. You might have luck with a file recovery utility. Also, be aware, using rm changes the table of contents to mark those blocks as available to be overwritten, so simply using your computer right now risks those blocks being overwritten permanently. If it's critical data, you should turn off the computer before the file sectors gets overwritten. Good luck!

Does not work for multidimensional arrays, because references are used here.

import numpy as np

# swaps
data = np.random.random(2)
print(data)
data[0], data[1] = data[1], data[0]
print(data)

# does not swap
data = np.random.random((2, 2))
print(data)
data[0], data[1] = data[1], data[0]
print(data)

See also Swap slices of Numpy arrays

Just for completeness as nobody else has mentioned it. The third parameter to an array slice is a step. So reversing a string is as simple as:

some_string[::-1]

Or selecting alternate characters would be:

"H-e-l-l-o- -W-o-r-l-d"[::2] # outputs "Hello World"

The ability to step forwards and backwards through the string maintains consistency with being able to array slice from the start or end.

Here is an example code. You can turn on/off flags to hide/show specific parts.

public static void hideSystemUI(Activity activity) {
    View decorView = activity.getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    //| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    //| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                    | View.SYSTEM_UI_FLAG_IMMERSIVE);
}

Then, you reset to the default state:

public static void showSystemUI(Activity activity) {
    View decorView = activity.getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

You can call the above functions from your onCreate:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.course_activity);
    UiUtils.hideSystemUI(this);
}

Building on John Riselvato's answer, to retrieve the string back from the UIAlertView...

alert.addAction(UIAlertAction(title: "Submit", style: UIAlertAction.Style.default) { (action : UIAlertAction) in
            guard let message = alert.textFields?.first?.text else {
                return
            }
            // Text Field Response Handling Here
        })

As a checkbox click = a checkbox change the following will also work:

<CheckBox Click="CheckBox_Click" />

private void CheckBox_Click(object sender, RoutedEventArgs e)
{
    // ... do some stuff
}

It has the additional advantage of working when IsThreeState="True" whereas just handling Checked and Unchecked does not.

JSONObject class has a method named "has". Returns true if this object has a mapping for name. The mapping may be NULL. http://developer.android.com/reference/org/json/JSONObject.html#has(java.lang.String)

An ES6 solution that uses several detection techniques within a try/catch block

The function consists of creating a "TouchEvent", seeking support for the "ontouchstart" event or even making a query to the mediaQueryList object.

Purposely, some queries that fail will throw a new error because as we are in a try/catch block we can use it as a fall back to consult the user agent.

I have no usage tests and in many cases it can fail as well as point out false positives.

It should not be used for any kind of real validation but, in a general scope for analysis and statistics where the volume of data can "forgive" the lack of precision, it may still be useful.

The regex used to test the user agent is a little old and was available on the website http://mobiledetect.com which is no longer in operation.

Maybe there is a better pattern but, I don't know.

Fonts:

• TouchEvent: https://developer.mozilla.org/en-US/docs/Web/API/TouchEvent
• ontouchstart: https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/ontouchstart
• mediaQueryList: https://developer.mozilla.org/en-US/docs/Web/API/MediaQueryList

PS:

As there is no way to identify with 100% accuracy neither by checking features, nor by examining the user agent string with regular expressions. The code snippet above should be seen only as: "one more example for this issue", as well as: "not recommended for use in production".

Building on Yogi's answer, here's a Swift function that does the job:

func roundToPlaces(value:Double, places:Int) -> Double {
    let divisor = pow(10.0, Double(places))
    return round(value * divisor) / divisor
}

You don't need to use jQuery for this!

The native JavaScript implementation is Date.now().

Date.now() and $.now() return the same value:

Date.now(); // 1421715573651
$.now();    // 1421715573651

new Date(Date.now())   // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)
new Date($.now());     // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)

..and if you want the time formatted in hh-mm-ss:

var now = new Date(Date.now());
var formatted = now.getHours() + ":" + now.getMinutes() + ":" + now.getSeconds();
// 20:10:58

In MATLAB R2015a or newer, it is no longer necessary (or advisable from a performance standpoint) to use fspecial followed by imfilter since there is a new function called imgaussfilt that performs this operation in one step and more efficiently.

The basic syntax:

B = imgaussfilt(A,sigma) filters image A with a 2-D Gaussian smoothing kernel with standard deviation specified by sigma.

The size of the filter for a given Gaussian standard deviation (sigam) is chosen automatically, but can also be specified manually:

B = imgaussfilt(A,sigma,'FilterSize',[3 3]);

The default is 2*ceil(2*sigma)+1.

Additional features of imgaussfilter are ability to operate on gpuArrays, filtering in frequency or spacial domain, and advanced image padding options. It looks a lot like IPP... hmmm. Plus, there's a 3D version called imgaussfilt3.

In the case of winforms:

If you include the images to your resources you can do it like this, very simple and straight forward:

public Form1()
          {
               InitializeComponent();
               button1.MouseEnter += new EventHandler(button1_MouseEnter);
               button1.MouseLeave += new EventHandler(button1_MouseLeave);
          }

          void button1_MouseLeave(object sender, EventArgs e)
          {
               this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img1));
          }


          void button1_MouseEnter(object sender, EventArgs e)
          {
               this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
          }

I would not recommend hardcoding image paths.

As you have altered your question ...

There is no (on)MouseOver in winforms afaik, there are MouseHover and MouseMove events, but if you change image on those, it will not change back, so the MouseEnter + MouseLeave are what you are looking for I think. Anyway, changing the image on Hover or Move :

in the constructor:
button1.MouseHover += new EventHandler(button1_MouseHover); 
button1.MouseMove += new MouseEventHandler(button1_MouseMove);

void button1_MouseMove(object sender, MouseEventArgs e)
          {
               this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
          }

          void button1_MouseHover(object sender, EventArgs e)
          {
               this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
          }

To add images to your resources: Projectproperties/resources/add/existing file

If you want to use it in JavaScript then you can use

str.replace("SP","\\SP");

But in Java

str.replaceAll("SP","\\SP");

will work perfectly.

SP: special character

Otherwise you can use Apache's EscapeUtil. It will solve your problem.

You could use ol' good easy_install zipline instead.

easy_install isn't pip but one good aspect of it is the ability to download and install binary packages too, which would free you for the need having VC++ ready. This of course relies of the assumption that the binaries were prepared for your Python version.

UPDATE:

Yes, Pip can install binaries now!

There's a new binary Python archive format (wheel) that is supposed to replace "eggs". Wheels are already supported by pip. This means you'll be able to install zipline with pip without compiling it as soon as someone builds the wheel for your platform and uploads it to PyPI.

Similar to @Piotr Lewandowski's answer, but within a forEach:

const config: MyConfig = { ... };

Object.keys(config)
  .forEach((key: keyof MyConfig) => {
    if (config[key]) {
      // ...
    }
  });

IE filters plus CSS transforms (Safari and Firefox).

IE's support is the oldest, Safari has [at least some?] support in 3.1.2, and Firefox won't have support until 3.1.

Alternatively, I would recommend a mix of Canvas/VML or SVG/VML. (Canvas has wider support.)

Here is another solution (only relevant declarations listed):

.text span {
   display:inline-block;
   margin-right:100%;
}

When the margin is expressed in percentage, that percentage is taken from the width of the parent node, so 100% means as wide as the parent, which results in the next element getting "pushed" to a new line.

headers = { 'User-Agent' : 'Mozilla/5.0' }
req = urllib2.Request('www.example.com', None, headers)
html = urllib2.urlopen(req).read()

Or, a bit shorter:

req = urllib2.Request('www.example.com', headers={ 'User-Agent': 'Mozilla/5.0' })
html = urllib2.urlopen(req).read()

I'm not an expert. But you can try

git fsck --full --no-reflogs | grep commit

to find the HEAD commit of deleted branch and get them back.

There is two way for hide a element

1. Use the "hidden" html attribute But in angular you can bind it with one or more fields like this :

   <input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden">

2.Better way of doing this is to use " *ngIf " directive like this :

<input class="txt" type="password" [(ngModel)]="input_pw" *ngIf="!isHidden">

Now why this is a better way because it doesn't just hide the element, it will removes it from the html code so this will help your page to render.

Gradle Build Tools 2.2.0+ - The closest the NDK has ever come to being called 'magic'

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

Android Studio Clean and Build Integration - DEPRECATED

The other answers do point out the correct way to prevent the automatic creation of Android.mk files, but they fail to go the extra step of integrating better with Android Studio. I have added the ability to actually clean and build from source without needing to go to the command-line. Your local.properties file will need to have ndk.dir=/path/to/ndk

apply plugin: 'com.android.application'

android {
    compileSdkVersion 14
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.application"
        minSdkVersion 14
        targetSdkVersion 14

        ndk {
            moduleName "YourModuleName"
        }
    }

    sourceSets.main {
        jni.srcDirs = [] // This prevents the auto generation of Android.mk
        jniLibs.srcDir 'src/main/libs' // This is not necessary unless you have precompiled libraries in your project.
    }

    task buildNative(type: Exec, description: 'Compile JNI source via NDK') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                '-j', Runtime.runtime.availableProcessors(),
                'all',
                'NDK_DEBUG=1'
    }

    task cleanNative(type: Exec, description: 'Clean JNI object files') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                'clean'
    }

    clean.dependsOn 'cleanNative'

    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn buildNative
    }
}

dependencies {
    compile 'com.android.support:support-v4:20.0.0'
}

The src/main/jni directory assumes a standard layout of the project. It should be the relative from this build.gradle file location to the jni directory.

Gradle - for those having issues

Also check this Stack Overflow answer.

It is really important that your gradle version and general setup are correct. If you have an older project I highly recommend creating a new one with the latest Android Studio and see what Google considers the standard project. Also, use gradlew. This protects the developer from a gradle version mismatch. Finally, the gradle plugin must be configured correctly.

And you ask what is the latest version of the gradle plugin? Check the tools page and edit the version accordingly.

Final product - /build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

// Running 'gradle wrapper' will generate gradlew - Getting gradle wrapper working and using it will save you a lot of pain.
task wrapper(type: Wrapper) {
    gradleVersion = '2.2'
}

// Look Google doesn't use Maven Central, they use jcenter now.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Make sure gradle wrapper generates the gradlew file and gradle/wrapper subdirectory. This is a big gotcha.

ndkDirectory

This has come up a number of times, but android.ndkDirectory is the correct way to get the folder after 1.1. Migrating Gradle Projects to version 1.0.0. If you're using an experimental or ancient version of the plugin your mileage may vary.

So by default you can open CMD and write

java -jar jenkins.war

But if your port 8080 is already is in use,so you have to change the Jenkins port number, so for that open Jenkins folder in Program File and open Jenkins.XML file and change the port number such as 8088

Now Open CMD and write

java -jar jenkins.war --httpPort=8088

When using the answer from David Poole I get a SystemError with gray scale PNGs and maybe other files. My solution is:

import numpy as np
from PIL import Image

img = Image.open( filename )
try:
    data = np.asarray( img, dtype='uint8' )
except SystemError:
    data = np.asarray( img.getdata(), dtype='uint8' )

Actually img.getdata() would work for all files, but it's slower, so I use it only when the other method fails.

?So if you use pipeline, it would close all other streams and make sure that there are no memory leaks.

Working example:

const http = require('http');
const { pipeline } = require('stream');
const fs = require('fs');

const file = fs.createWriteStream('./file.jpg');

http.get('http://via.placeholder.com/150/92c952', response => {
  pipeline(
    response,
    file,
    err => {
      if (err)
        console.error('Pipeline failed.', err);
      else
        console.log('Pipeline succeeded.');
    }
  );
});

From my answer to "What's the difference between .pipe and .pipeline on streams".

for Python 3 users. you can do

with open(csv_name_here, 'r', encoding="utf-8") as f:
    #some codes

it works with flask too :)

in IntelliJ 2020 in the pom.xml view one should be able to apply pom changes by following key combination: CTRG + SHIFT + O.

And as correctly commented before - IntelliJ additionally shows a balloon widget to import changes.

I encountered the same problem when I tried to install curl in my 32 bit win 7 machine. As answered by Buravchik it is indeed dependency of SSL and installing openssl fixed it. Just a point to take care is that while installing openssl you will get a prompt to ask where do you wish to put the dependent DLLS. Make sure to put it in windows system directory as other programs like curl and wget will also be needing it.

Use css calc()

Super simple and awesome.

input {
    width: -moz-calc(100% - 15px);
    width: -webkit-calc(100% - 15px);
    width: calc(100% - 15px);
}?

As seen here: Div width 100% minus fixed amount of pixels

MacOS: composer is available on brew now (Tested on Php7+):

brew install composer

Install instructions on the Composer Docs page are quite to the point otherwise.

With Qt backend (FigureManagerQT) proper command is:

figManager = plt.get_current_fig_manager()
figManager.window.showMaximized()

That's another solution (Spring Security 3):

public String getLoggedUser() throws Exception {
    String name = SecurityContextHolder.getContext().getAuthentication().getName();
    return (!name.equals("anonymousUser")) ? name : null;
}

Make sure you have MainActivity and .ScanActivity into your AndroidManifest.xml file:

<activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".ScanActivity">

    </activity>

I use this query to get it:

SELECT name FROM sqlite_master WHERE type='table'

And to use in iOS:

NSString *aStrQuery=[NSString stringWithFormat:@"SELECT name FROM sqlite_master WHERE type='table'"];

You may try the following: Open anaconda command prompt and type

conda remove --name myenv --all

This will remove the entire environment.

You are encountering the float bug (though I'm not sure if it's technically a bug due to how many browsers exhibit this behaviour). Here is what is happening:

Under normal circumstances, assuming that no explicit height has been set, a block level element such as a div will set its height based on its content. The bottom of the parent div will extend beyond the last element. Unfortunately, floating an element stops the parent from taking the floated element into account when determining its height. This means that if your last element is floated, it will not "stretch" the parent in the same way a normal element would.

Clearing

There are two common ways to fix this. The first is to add a "clearing" element; that is, another element below the floated one that will force the parent to stretch. So add the following html as the last child:

<div style="clear:both"></div>

It shouldn't be visible, and by using clear:both, you make sure that it won't sit next to the floated element, but after it.

Overflow:

The second method, which is preferred by most people (I think) is to change the CSS of the parent element so that the overflow is anything but "visible". So setting the overflow to "hidden" will force the parent to stretch beyond the bottom of the floated child. This is only true if you haven't set a height on the parent, of course.

Like I said, the second method is preferred as it doesn't require you to go and add semantically meaningless elements to your markup, but there are times when you need the overflow to be visible, in which case adding a clearing element is more than acceptable.

Nothing worked for me until I updated my kotlin plugin dependency.
Try this:
1. Invalidate cahce and restart.
2. Sync project (at least try to)
3. Go File -> Project Structure -> Suggestions
4. If there is an update regarding Kotlin, update it.
Hope it will help someone.

After spending hours on this issue, none of the answers above helped me so I found a really useful tool.

Firstly, I used Telerik's Fiddler 4 to study my Web Requests in details

Secondly, I came across this useful plugin for Fiddler:

https://github.com/sunilpottumuttu/FiddlerGenerateHttpClientCode

It will just generate the C# code for you. An example was:

        var uriBuilder = new UriBuilder("test.php", "test");
        var httpClient = new HttpClient();


        var httpRequestMessage = new HttpRequestMessage(HttpMethod.Post, uriBuilder.ToString());



        httpRequestMessage.Headers.Add("Host", "test.com");
        httpRequestMessage.Headers.Add("Connection", "keep-alive");
     //   httpRequestMessage.Headers.Add("Content-Length", "138");
        httpRequestMessage.Headers.Add("Pragma", "no-cache");
        httpRequestMessage.Headers.Add("Cache-Control", "no-cache");
        httpRequestMessage.Headers.Add("Origin", "test.com");
        httpRequestMessage.Headers.Add("Upgrade-Insecure-Requests", "1");
    //    httpRequestMessage.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
        httpRequestMessage.Headers.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36");
        httpRequestMessage.Headers.Add("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8");
        httpRequestMessage.Headers.Add("Referer", "http://www.translationdirectory.com/");
        httpRequestMessage.Headers.Add("Accept-Encoding", "gzip, deflate");
        httpRequestMessage.Headers.Add("Accept-Language", "en-GB,en-US;q=0.9,en;q=0.8");
        httpRequestMessage.Headers.Add("Cookie", "__utmc=266643403; __utmz=266643403.1537352460.3.3.utmccn=(referral)|utmcsr=google.co.uk|utmcct=/|utmcmd=referral; __utma=266643403.817561753.1532012719.1537357162.1537361568.5; __utmb=266643403; __atuvc=0%7C34%2C0%7C35%2C0%7C36%2C0%7C37%2C48%7C38; __atuvs=5ba2469fbb02458f002");


        var httpResponseMessage = httpClient.SendAsync(httpRequestMessage).Result;

        var httpContent = httpResponseMessage.Content;
        string result = httpResponseMessage.Content.ReadAsStringAsync().Result;

Note that I had to comment out two lines as this plugin is not totally perfect yet but it did the job nevertheless.

DISCLAIMER: I am not associated or endorsed by either Telerik or the plugin's author in anyway.

It's 2020 and stuffs had greatly evolved with php 7.4 and opcache.

Here is the OP^ benchmark, ran as unix CLI, without the echo and html parts.

Test ran locally on a regular computer.

PHP 7.4.6 (cli) (built: May 14 2020 10:02:44) ( NTS )

Modified benchmark script:

As you can see the evolution is insane, about 560 time faster than reported in 2012.

On my machines and servers, following my numerous experiments, basics for loops are the fastest. This is even clearer using nested loops ($i $j $k..)

It is also the most flexible in usage, and has a better readability from my view.

Just simply use the encode function.

my_var = 'hello'
my_var_bytes = my_var.encode()
print(my_var_bytes)

And then to convert it back to a regular string do this

my_var_bytes = 'hello'
my_var = my_var_bytes.decode()
print(my_var)

--EDIT--

The following does not make the string raw but instead encodes it to bytes and decodes it.

I wish #pragma once (or something like it) had been in the standard. Include guards aren't a real big deal (but they do seem to be a little difficult to explain to people learning the language), but it seems like a minor annoyance that could have been avoided.

In fact, since 99.98% of the time, the #pragma once behavior is the desired behavior, it would have been nice if preventing multiple inclusion of a header was automatically handled by the compiler, with a #pragma or something to allow double including.

But we have what we have (except that you might not have #pragma once).

From Spring's AnnotationTransactionAspect:

/**
 * Matches the execution of any public method in a type with the Transactional
 * annotation, or any subtype of a type with the Transactional annotation.
 */
private pointcut executionOfAnyPublicMethodInAtTransactionalType() :
    execution(public * ((@Transactional *)+).*(..)) && within(@Transactional *);

There are various method to refresh the page in asp.net like...

Java Script

 function reloadPage()
 {
     window.location.reload()
 }

Code Behind

Response.Redirect(Request.RawUrl)

Meta Tag

<meta http-equiv="refresh" content="600"></meta>

Page Redirection

Response.Redirect("~/default.aspx"); // Or whatever your page url

You can use Q objects for this. They can be negated with the ~ operator and combined much like normal Python expressions:

from myapp.models import Entry
from django.db.models import Q

Entry.objects.filter(~Q(id=3))

will return all entries except the one(s) with 3 as their ID:

[<Entry: Entry object>, <Entry: Entry object>, <Entry: Entry object>, ...]

 while (rs.next()) {

            customer.setId(rs.getInt("id"));
            customer.setName(rs.getString("name"));

            customer.setAddress(rs.getString("address"));
            customer.setPhone(rs.getString("phone"));
            customer.setEmail(rs.getString("email"));
            customer.setBountPoints(rs.getInt("bonuspoint"));
            customer.setTotalsale(rs.getInt("totalsale"));

            customers.add(customer);
             customer = null;
        }

Try replacing your while loop code with above mentioned code. Here what we have done is after doing customers.add(customer) we are doing customer = null;`

If you named your class with the keyword in Java, your program wouldn't be recognized that it had the main method.

If you want to use names, try a namedtuple:

from collections import namedtuple

Pair = namedtuple("Pair", ["first", "second"])

pairs = [Pair("a", 1), Pair("b", 2), Pair("c", 3)]

for pair in pairs:
    print("First = {}, second = {}".format(pair.first, pair.second))

Here's a cross browser working function (usable for other than click handlers too):

function eventFire(el, etype){
    if (el.fireEvent) {
      el.fireEvent('on' + etype);
    } else {
      var evObj = document.createEvent('Events');
      evObj.initEvent(etype, true, false);
      el.dispatchEvent(evObj);
    }
}

String myString = getString(R.string.mystring);

easy way

Here's a simple answer for these days of modern C++ (C++11 and later):

• "What is a smart pointer?"
  It's a type whose values can be used like pointers, but which provides the additional feature of automatic memory management: When a smart pointer is no longer in use, the memory it points to is deallocated (see also the more detailed definition on Wikipedia).
• "When should I use one?"
  In code which involves tracking the ownership of a piece of memory, allocating or de-allocating; the smart pointer often saves you the need to do these things explicitly.
• "But which smart pointer should I use in which of those cases?"
  • Use std::unique_ptr when you want your object to live just as long as a single owning reference to it lives. For example, use it for a pointer to memory which gets allocated on entering some scope and de-allocated on exiting the scope.
  • Use std::shared_ptr when you do want to refer to your object from multiple places - and do not want your object to be de-allocated until all these references are themselves gone.
  • Use std::weak_ptr when you do want to refer to your object from multiple places - for those references for which it's ok to ignore and deallocate (so they'll just note the object is gone when you try to dereference).
  • Don't use the boost:: smart pointers or std::auto_ptr except in special cases which you can read up on if you must.
• "Hey, I didn't ask which one to use!"
  Ah, but you really wanted to, admit it.
• "So when should I use regular pointers then?"
  Mostly in code that is oblivious to memory ownership. This would typically be in functions which get a pointer from someplace else and do not allocate nor de-allocate, and do not store a copy of the pointer which outlasts their execution.

Take a look at Simple JavaScript Inheritance and Inheritance Patterns in JavaScript.

The simplest method is probably functional inheritance but there are pros and cons.

The upcoming change is for chinese, arabic domain names not URIs. The internationalised URIs are called IRIs and are defined in RFC 3987. However, having said that I'd recommend not doing this yourself but relying on an existing, tested library since there are lots of choices of URI encoding/decoding and what are considered safe by specification, versus what are safe by actual use (browsers).

Just tested:

Run the following command:

sudo shred -u /etc/ssh/*_key /etc/ssh/*_key.pub

Then:

1. create ami (image of the ec2).
2. launch from new ami(image) from step no 2 chose new keys.

please note, if you use $filter like this:

$scope.failedSubjects = $filter('filter')($scope.results.subjects, {'grade':'C'});

and you happened to have another grade for, Oh I don't know, CC or AC or C+ or CCC it pulls them in to. you need to append a requirement for an exact match:

$scope.failedSubjects = $filter('filter')($scope.results.subjects, {'grade':'C'}, true);

This really killed me when I was pulling in some commission details like this:

var obj = this.$filter('filter')(this.CommissionTypes, { commission_type_id: 6}))[0];

only get called in for a bug because it was pulling in the commission ID 56 rather than 6.

Adding the true forces an exact match.

var obj = this.$filter('filter')(this.CommissionTypes, { commission_type_id: 6}, true))[0];

Yet still, I prefer this (I use typescript, hence the "Let" and =>):

let obj = this.$filter('filter')(this.CommissionTypes, (item) =>{ 
             return item.commission_type_id === 6;
           })[0];

I do that because, at some point down the road, I might want to get some more info from that filtered data, etc... having the function right in there kind of leaves the hood open.

No.

You can use grouping selectors and/or multiple classes on a single element, or you can use a template language and process it with software to write your CSS.

See also my article on CSS inheritance.

You need the Apache Commons Codec library 1.4 or above in your classpath. This library contains Base64 implementation.

you can use this func

 class func stringIsNilOrEmpty(aString: String) -> Bool { return (aString).isEmpty }

Include a few #ifndef name #define name #endif preprocessor that should solve your problem. The issue is it going from the header to the function then back to the header so it is redefining the class with all the preprocessor(#include) multiple times.

Simply track your remote branches explicitly and a simple git pull will do just what you want:

git branch -f remote_branch_name origin/remote_branch_name
git checkout remote_branch_name

The latter is a local operation.

Or even more fitting in with the GitHub documentation on forking:

git branch -f new_local_branch_name upstream/remote_branch_name

I am glad you were able to get this done in this manner, but you can (and I did) use the GParted tool for my Windows XP host by following the helpful entry by Eric. To re-iterate/expand on his solution (don't be afraid of the # steps, I'm trying to help newbies here, so there are necessarily more detailed instructions!):

1. change the size of the virtual hard disk via the VBoxManage modifyhd command, which is well-documented here and in the VirtualBox documentation.

2. download the GParted-live (http://sourceforge.net/projects/gparted/files/latest/download?source=dlp) or search the internet for GParted-live ISO. The important part is to get the live (.iso) verison, which is in the form of a bootable .ISO (CD) image.

3. Mount this new .ISO to the CD virtual drive in the host machine's Storage settings

4. If necessary/desired, change the boot order in the System settings for the host machine, to boot from CD before Hard Disk (alternatively, you can press F12 when it's booting up, and select the device)

5. start your VM; if you changed the boot order, it will boot to the GParted-live ISO; otherwise press F12 to do this.

6. do not be afraid or get too confused/wrapped up in the initial options you are presented; I selected all the defaults (booting to GParted default, default key mapping, language (assuming English - sorry for my non-English friends!), display, etc.). Read it, but just press enter at each prompt. With a Windows VM you should be fine with all the defaults, and if you're not, you're not going to break anything, and the instructions are pretty good about what to do if the defaults don't work.

7. it will boot to a GUI environment and start the GParted utility. Highlight the c: drive (assuming that's the drive you want to increase the size on) and select resize/move.

8. change to the new size you want in MB (they abbreviate MiB) - just add the new amount available (represented in the bottom number - MiB following) to the middle number. E.g: I changed mine from like 4000 MiB (e.g., 4GB - my initial size) to 15000 MiB (15 GB) because I'd added 10 GB to my virtual disk. Then click OK.

9. Click Apply. Once it's done you'll have to reboot - for whatever reason my mouse did not work on the desktop icons on the GUI (I could not click exit) so I just closed the VM window and selected reboot. I did not even have to unmount the ISO, it apparently did it automatically.

10. Let Windows go through the disk check - remember, you just changed the size outside of Windows, so it has no record of this. This will presumably allow it to update itself with the new info. Once it completes and you log in, you'll likely be told that Windows needs to reboot to use your 'new device' (at least in XP it did for me). Just reboot and you are done!

It's an old question, but I don't see mentioned that, depending on the details, the sharey option may be able to do all of this for you, instead of digging up axis limits, margins, etc. There's a demo in the docs that shows how to use sharex, but the same can be done with y-axes.

In case you have NA's:

sapply(data, mean, na.rm = T)      # Returns a vector (with names)   
lapply(data, mean, na.rm = T)      # Returns a list  

Remember that "mean" needs numeric data. If you have mixed class data, then use:

numdata<-data[sapply(data, is.numeric)]  
sapply(numdata, mean, na.rm = T)  # Returns a vector
lapply(numdata, mean, na.rm = T)  # Returns a list  

To resolve this error:

ORA-01653 unable to extend table by 1024 in tablespace your-tablespace-name

Just run this PL/SQL command for extended tablespace size automatically on-demand:

alter database datafile '<your-tablespace-name>.dbf' autoextend on maxsize unlimited;

I get this error in import big dump file, just run this command without stopping import routine or restarting the database.

Note: each data file has a limit of 32GB of size if you need more than 32GB you should add a new data file to your existing tablespace.

More info: alter_autoextend_on

Add /Q for quiet mode and it should remove the prompt.

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

One more way I've set up SQL Server queries to ignore milliseconds when I'm looking for events from a particular second (in a parameter in "YYYY-MM-DD HH:TT:SS" format) using a stored procedure:

  WHERE 
  ...[Time_stamp] >= CAST(CONCAT(@YYYYMMDDHHTTSS,'.000') as DateTime) AND 
  ...[Time_stamp] <= CAST(CONCAT(@YYYYMMDDHHTTSS,'.999') as DateTime) 

You could use something similar to ignore minutes and seconds too.

This is your html-

    <img id="imageid" src="">
    <canvas id="imgCanvas" />

Javascript should be-

   var can = document.getElementById("imgCanvas");
   var img = document.getElementById("imageid");
   var ctx = can.getContext("2d");
   ctx.drawImage(img, 10, 10);
   var encodedBase = can.toDataURL();

'encodedBase' Contains Base64 Encoding of Image.

by using jquery to register .mousemove to document to change the image .css left and top to event.pageX and event.pageY.

example as below http://jsfiddle.net/BfLAh/1/

$(document).mousemove(function(e) {
  $("#follow").css({
    left: e.pageX,
    top: e.pageY
  });
});

#follow {
  position: absolute;
  text-align: center;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="follow"><img src="https://placekitten.com/96/140" /><br>Kitteh</br>
</div>

updated to follow slowly

http://jsfiddle.net/BfLAh/3/

for the orientation , you need to get the current css left and css top and compare with event.pageX and event.pageY , then set the image orientation with

-webkit-transform: rotate(-90deg); 
-moz-transform: rotate(-90deg); 

for the speed , you can set the jquery .animation duration to certain amount.

You can use zip:

>>> a = [1, 2, 3]
>>> b = ['a', 'b', 'c']
>>> for x, y in zip(a, b):
...   print x, y
... 
1 a
2 b
3 c

You want to replace the Backslash?

Try stripcslashes:

http://www.php.net/manual/en/function.stripcslashes.php

Here is a more complete example:

import csv
import numpy as np

with open('filename','rb') as csvfile:
     cdl = list( csv.reader(csvfile,delimiter='\t'))
     print "Number of records = " + str(len(cdl))

#then later

npcdl = np.array(cdl)

Hope this helps!!

If you are looking for a free, nice looking, cross-platform editor, try Komodo Edit. It is not as powerful as Komodo IDE, however that isn't free. See feature chart.

Another free, extensible editor is jEdit. Crossplatform as it is 100% pure Java. Not the fastest IDE on earth, but for Java actually very fast, very flexible, not that nice looking though.

Both have very sophisticated code folding, syntax highlighting (for all languages you can think of!) and are very flexible regarding configuring it for you personal needs. jEdit is BTW very easy to extend to add whatever feature you may need there (it has an ultra simple scripting language, that looks like Java, but is actually "scripted").

Would the Python termcolor module do? This would be a rough equivalent for some uses.

from termcolor import colored

print colored('hello', 'red'), colored('world', 'green')

The example is right from this post, which has a lot more. Here is a part of the example from docs

import sys
from termcolor import colored, cprint

text = colored('Hello, World!', 'red', attrs=['reverse', 'blink'])
print(text)
cprint('Hello, World!', 'green', 'on_red')

A specific requirement was to set the color, and presumably other terminal attributes, so that all following prints are that way. While I stated in the original post that this is possible with this module I now don't think so. See the last section for a way to do that.

However, most of the time we print short segments of text in color, a line or two. So the interface in these examples may be a better fit than to 'turn on' a color, print, and then turn it off. (Like in the Perl example shown.) Perhaphs you can add optional argument(s) to your print function for coloring the output as well, and in the function use module's functions to color the text. This also makes it easier to resolve occasional conflicts between formatting and coloring. Just a thought.

Here is a basic approach to set the terminal so that all following prints are rendered with a given color, attributes, or mode.

Once an appropriate ANSI sequence is sent to the terminal, all following text is rendered that way. Thus if we want all text printed to this terminal in the future to be bright/bold red, print ESC[ followed by the codes for "bright" attribute (1) and red color (31), followed by m

# print "\033[1;31m"   # this would emit a new line as well
import sys
sys.stdout.write("\033[1;31m")
print "All following prints will be red ..."

To turn off any previously set attributes use 0 for attribute, \033[0;35m (magenta).

To suppress a new line in python 3 use print('...', end=""). The rest of the job is about packaging this for modular use (and for easier digestion).

File colors.py

RED   = "\033[1;31m"  
BLUE  = "\033[1;34m"
CYAN  = "\033[1;36m"
GREEN = "\033[0;32m"
RESET = "\033[0;0m"
BOLD    = "\033[;1m"
REVERSE = "\033[;7m"

I recommend a quick read through some references on codes. Colors and attributes can be combined and one can put together a nice list in this package. A script

import sys
from colors import *

sys.stdout.write(RED)
print "All following prints rendered in red, until changed"

sys.stdout.write(REVERSE + CYAN)
print "From now on change to cyan, in reverse mode"
print "NOTE: 'CYAN + REVERSE' wouldn't work"

sys.stdout.write(RESET)
print "'REVERSE' and similar modes need be reset explicitly"
print "For color alone this is not needed; just change to new color"
print "All normal prints after 'RESET' above."

If the constant use of sys.stdout.write() is a bother it can be be wrapped in a tiny function, or the package turned into a class with methods that set terminal behavior (print ANSI codes).

Some of the above is more of a suggestion to look it up, like combining reverse mode and color. (This is available in the Perl module used in the question, and is also sensitive to order and similar.)

A convenient list of escape codes is surprisingly hard to find, while there are many references on terminal behavior and how to control it. The Wiki page on ANSI escape codes has all information but requires a little work to bring it together. Pages on Bash prompt have a lot of specific useful information. Here is another page with straight tables of codes. There is much more out there.

This can be used alongside a module like termocolor.

Write one table per join, like this:

select tab1.a,tab2.b,tab3.c,tab4.d 
from 
  table1 tab1
  inner join table2 tab2 on tab2.fg = tab1.fg
  left join table3 tab3 on tab3.xxx = tab1.xxx and tab3.desc = "XYZ"
  left join table4 tab4 on tab4.xya = tab3.xya and tab4.ss = tab3.ss
  left join table5 tab5 on tab5.dd = tab3.dd and tab5.kk = tab4.kk

Note that while my query contains actual left join, your query apparently doesn't. Since the conditions are in the where, your query should behave like inner joins. (Although I admit I don't know Informix, so maybe I'm wrong there).

The specfific Informix extension used in the question works a bit differently with regards to left joins. Apart from the exact syntax of the join itself, this is mainly in the fact that in Informix, you can specify a list of outer joined tables. These will be left outer joined, and the join conditions can be put in the where clause. Note that this is a specific extension to SQL. Informix also supports 'normal' left joins, but you can't combine the two in one query, it seems.

In Oracle this extension doesn't exist, and you can't put outer join conditions in the where clause, since the conditions will be executed regardless.

So look what happens when you move conditions to the where clause:

select tab1.a,tab2.b,tab3.c,tab4.d 
from 
  table1 tab1
  inner join table2 tab2 on tab2.fg = tab1.fg
  left join table3 tab3 on tab3.xxx = tab1.xxx
  left join table4 tab4 on tab4.xya = tab3.xya
  left join table5 tab5 on tab5.dd = tab3.dd and tab5.kk = tab4.kk
where
  tab3.desc = "XYZ" and
  tab4.ss = tab3.ss

Now, only rows will be returned for which those two conditions are true. They cannot be true when no row is found, so if there is no matching row in table3 and/or table4, or if ss is null in either of the two, one of these conditions is going to return false, and no row is returned. This effectively changed your outer join to an inner join, and as such changes the behavior significantly.

PS: left join and left outer join are the same. It means that you optionally join the second table to the first (the left one). Rows are returned if there is only data in the 'left' part of the join. In Oracle you can also right [outer] join to make not the left, but the right table the leading table. And there is and even full [outer] join to return a row if there is data in either table.

I changed the header and footer of the PEM file to

-----BEGIN RSA PRIVATE KEY-----

and

-----END RSA PRIVATE KEY-----

Finally, it works!

On Amazon Linux 2 and PHP 7.4 I finally got PHP-ZIP to install and I hope it helps someone else - by the following (note the yum install command has extra common modules also included you may not need them all):

sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

sudo yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

sudo yum -y install yum-utils

sudo yum-config-manager --enable remi-php74

sudo yum update

sudo yum install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json

sudo pecl install zip

php --modules

sudo systemctl restart httpd

You can do this in pretty concise way using ResponseEntity like this:

  @GetMapping
  ResponseEntity<Void> redirect() {
    return ResponseEntity.status(HttpStatus.FOUND)
        .location(URI.create("http://www.yahoo.com"))
        .build();
  }

First method (internal function)

The best way I have tried before is to use urlencode(). Keep in mind, don't use it for the whole url; instead, use it only for the needed parts. For example, a request that has two 'text-fa' and 'text-en' fields and they contain a Persian and an English text, respectively, you might only need to encode the Persian text, not the English one.

Second Method (using cURL function)

However, there are better ways if the range of characters have to be encoded is more limited. One of these ways is using CURLOPT_ENCODING, by passing it to curl_setopt():

curl_setopt($ch, CURLOPT_ENCODING, "");

The Object answer above does not seem to work for me in my use case with Objects.

I have modified it as follows:

var j = {};

this.forEach( function(v) {
   var typ = typeof v;
   var v = (typ === 'object') ? JSON.stringify(v) : v;

   j[v + '::' + typ] = v;
});

return Object.keys(j).map(function(v){
  if ( v.indexOf('::object') > -1 ) {
    return JSON.parse(j[v]);
  }

  return j[v];
});

This seems to now work correctly for objects, arrays, arrays with mixed values, booleans, etc.

You might want to consider using console.log with the built-in "arguments" object:

console.log(arguments); // would have shown you [0] null, [1] yourResult

This will always output all of your arguments, no matter how many arguments you have.

In my case, I had a repo with:

• requirements A,B,C,D in .json
• but only A,B,C in the .lock

In the meantime, A,B,C had newer versions with respect when the lock was generated.

For some reason, I deleted the "vendors" and wanted to do a composer install and failed with the message:

Warning: The lock file is not up to date with the latest changes in composer.json.
You may be getting outdated dependencies. Run update to update them.
Your requirements could not be resolved to an installable set of packages.

I tried to run the solution from Seldaek issuing a composer update vendorD/libraryD but composer insisted to update more things, so .lock had too changes seen my my git tool.

The solution I used was:

1. Delete all the vendors dir.
2. Temporarily remove the requirement VendorD/LibraryD from the .json.
3. run composer install.
4. Then delete the file .json and checkout it again from the repo (equivalent to re-adding the file, but avoiding potential whitespace changes).
5. Then run Seldaek's solution composer update vendorD/libraryD

It did install the library, but in addition, git diff showed me that in the .lock only the new things were added without editing the other ones.

(Thnx Seldaek for the pointer ;) )

linux os terminal run this :

  keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass androi

You can pass a mutable container datatype into a function, and it can contain anything you want.

If you need a different functionality, name the functions differently, or if you need the same interface, just write an interface function (or method) that calls the functions appropriately based on the data received.

It took a while to me to get adjusted to this coming from Java, but it really isn't a "big handicap".

You can also use:

@using (Html.BeginForm("Upload", "File", FormMethod.Post, new { enctype = "multipart/form-data" }))
{ 
    <p>
        <input type="file" id="fileUpload" name="fileUpload" size="23" />
    </p>
    <p>
        <input type="submit" value="Upload file" /></p> 
}

It means that if x is set, the value for z will be x, otherwise if y is set then its value will be set as the z's value.

it's the same as

if(x)
  z = x;
else
  z = y;

It's possible because logical operators in JavaScript doesn't return boolean values but the value of the last element needed to complete the operation (in an OR sentence it would be the first non-false value, in an AND sentence it would be the last one). If the operation fails, then false is returned.

Since ES6 filter supports pointy arrow notation (like LINQ):

So it can be boiled down to following one-liner.

['a','b',1].filter(item => typeof item ==='string');

I am new to Python. I got the code below working and made it easy to understand:

my_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
for str in my_list:
    if 'abc' in str:
       print(str)

There are a few different libraries doing parsing of Excel files (.xlsx). I will list two projects I find interesting and worth looking into.

Node-xlsx

Excel parser and builder. It's kind of a wrapper for a popular project JS-XLSX, which is a pure javascript implementation from the Office Open XML spec.

node-xlsx project page

Example for parsing file

var xlsx = require('node-xlsx');

var obj = xlsx.parse(__dirname + '/myFile.xlsx'); // parses a file

var obj = xlsx.parse(fs.readFileSync(__dirname + '/myFile.xlsx')); // parses a buffer

ExcelJS

Read, manipulate and write spreadsheet data and styles to XLSX and JSON. It's an active project. At the time of writing the latest commit was 9 hours ago. I haven't tested this myself, but the api looks extensive with a lot of possibilites.

exceljs project page

Code example:

// read from a file
var workbook = new Excel.Workbook();
workbook.xlsx.readFile(filename)
    .then(function() {
        // use workbook
    });

// pipe from stream
var workbook = new Excel.Workbook();
stream.pipe(workbook.xlsx.createInputStream());

As said in the comments, the problem lies in your script. Actually, there are 2 problems:

• There is a matplotlib error, I guess that you're passing an argument as None somewhere. Maybe due to the defaultdict ?
• You call show() after each subplot. show() should be called once at the end of your script. The alternative is to use interactive mode, look for ion in matplotlib's documentation.

Use parseLong(), e.g.:

long lg = lg.parseLong("123456789123456789");

Output the images in a lossless format such as PNG:

ffmpeg.exe -i 10fps.h264 -r 10 -f image2 10fps.h264_%03d.png

Edit/Update: Not quite sure why I originally gave a strange filename example (with a possibly made-up extension).

I have since found that -vsync 0 is simpler than -r 10 because it avoids needing to know the frame rate.

This is something like what I currently use:

mkdir stills
ffmpeg -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

To extract only the key frames (which are likely to be of higher quality post-edit):

ffmpeg -skip_frame nokey -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

Then use another program (where you can more precisely specify quality, subsampling and DCT method – e.g. GIMP) to convert the PNGs you want to JPEG.

It is possible to obtain slightly sharper images in JPEG format this way than is possible with -qmin 1 -q:v 1 and outputting as JPEG directly from ffmpeg.

I was having the same issue and none of the above made any difference for me what did work was having my location php above any other location blocks.

location ~ [^/]\.php(/|$) {
fastcgi_split_path_info  ^(.+\.php)(/.+)$;
fastcgi_index            index.php;
fastcgi_pass             unix:/var/run/php/php7.3-fpm.sock;
include                  fastcgi_params;
fastcgi_param   PATH_INFO       $fastcgi_path_info;
fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
** The below is specifically for moodle **
location /dataroot/ {
internal;
alias <full_moodledata_path>; # ensure the path ends with /
}

Your code is OK. Note though that if you return a pointer to an array, and that array goes out of scope, you should not use that pointer anymore. Example:

int* test (void)
{
    int out[5];
    return out;
}

The above will never work, because out does not exist anymore when test() returns. The returned pointer must not be used anymore. If you do use it, you will be reading/writing to memory you shouldn't.

In your original code, the arr array goes out of scope when main() returns. Obviously that's no problem, since returning from main() also means that your program is terminating.

If you want something that will stick around and cannot go out of scope, you should allocate it with new:

int* test (void)
{
    int* out = new int[5];
    return out;
}

The returned pointer will always be valid. Remember do delete it again when you're done with it though, using delete[]:

int* array = test();
// ...
// Done with the array.
delete[] array;

Deleting it is the only way to reclaim the memory it uses.

You DO NOT NEED to replace the comma and dot..

I have had the very same problem. The reason is simple, the conversion culture plays a big role in which the comma or a dot is interpreted. I use a German culture where the comma distinguish the fractions, where as elsewhere the dot does the job.

Here I made a complete example to make the difference clear.

string[] doubleStrings = {"hello", "0.123", "0,123"};
double localCultreResult;
foreach (var doubleString in doubleStrings)
{
    double.TryParse(doubleString, NumberStyles.Any, CultureInfo.CurrentCulture, out localCultreResult);
    Console.WriteLine(string.Format("Local culture results for the parsing of {0} is {1}", doubleString, localCultreResult));
}

double invariantCultureResult;
foreach (var doubleString in doubleStrings)
{
    double.TryParse(doubleString, NumberStyles.Any, CultureInfo.InvariantCulture, out invariantCultureResult);
    Console.WriteLine(string.Format("Invariant culture results for the parsing of {0} is {1}", doubleString, invariantCultureResult));
}

The results is the following:

Play around with the culture and you will get the result you need.

This is what I did to fix the problem:

$sudo mkdir -p /data/db

$export PATH=/usr/local/Cellar/mongodb/3.0.7/bin:$PATH

$sudo chown -R id -u /data/db

and then to start mongo...

$mongod

There is still another way to do it, which is using a particular NamingStrategy, which can be applied to a class or a property by decorating them with [JSonObject] or [JsonProperty].

There are predefined naming strategies like CamelCaseNamingStrategy, but you can implement your own ones.

The implementation of different naming strategies can be found here: https://github.com/JamesNK/Newtonsoft.Json/tree/master/Src/Newtonsoft.Json/Serialization

DID NOT WORK:

I have already had the following dependency in my build.gradle

implementation 'com.android.support:support-v13:26.0.2'

I have tried all of the following,

• Invalidate Caches/Restart
• Sync project with gradle files
• Clean project
• Rebuild project
• gradlew clean

But, none of them worked for me.

SOLUTION:

Finally, I solved it by deleting "/.idea/libraries", and then synced with gradle and built again.

WARNING: it will delete untracked files, so it's not a great answer to the question being posed.

I hit this message as well. In my case, I didn't want to keep the files, so this worked for me:

git 2.11 and newer

git clean  -d  -f .

older git

git clean  -d  -f ""

If you also want to remove files ignored by git, then execute the following command.

BE WARNED!!! THIS MOST PROBABLY DESTROYS YOUR PROJECT, USE ONLY IF YOU KNOW 100% WHAT YOU ARE DOING

git 2.11 and newer

git clean  -d  -fx .

older git

git clean  -d  -fx ""

http://www.kernel.org/pub/software/scm/git/docs/git-clean.html

• -x means ignored files are also removed as well as files unknown to git.

• -d means remove untracked directories in addition to untracked files.

• -f is required to force it to run.

For a dictionary, you're best of encoding to JSON first. You can use simplejson.dumps() or if you want to convert from a data model in App Engine, you could use encode() from the GQLEncoder library.

For deep cloning implement Serializable on every class you want to clone like this

public static class Obj implements Serializable {
    public int a, b;
    public Obj(int a, int b) {
        this.a = a;
        this.b = b;
    }
}

And then use this function:

public static Object deepClone(Object object) {
    try {
        ByteArrayOutputStream baOs = new ByteArrayOutputStream();
        ObjectOutputStream oOs = new ObjectOutputStream(baOs);
        oOs.writeObject(object);
        ByteArrayInputStream baIs = new ByteArrayInputStream(baOs.toByteArray());
        ObjectInputStream oIs = new ObjectInputStream(baIs);
        return oIs.readObject();
    }
    catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

like this: Obj newObject = (Obj)deepClone(oldObject);

If you want the length of the character array use sizeof(array)/sizeof(array[0]), if you want the length of the string use strlen(array).

I tried to edit the answer provided by marc_s however it wasn't accepted for some reason. It formats the sql for easier reading, includes the schema and also names the Default name so that this can easily be pasted into other code.

  SELECT SchemaName = s.Name,
         TableName = t.Name,
         ColumnName = c.Name,
         DefaultName = dc.Name,
         DefaultDefinition = dc.Definition
    FROM sys.schemas                s
    JOIN sys.tables                 t   on  t.schema_id          = s.schema_id
    JOIN sys.default_constraints    dc  on  dc.parent_object_id  = t.object_id 
    JOIN sys.columns                c   on  c.object_id          = dc.parent_object_id
                                        and c.column_id          = dc.parent_column_id
ORDER BY s.Name, t.Name, c.name

Android comes with a built-in YesNoPreference class that does exactly what you want (a confirm dialog with yes and no options). See the official source code here.

Unfortunately, it is in the com.android.internal.preference package, which means it is a part of Android's private APIs and you cannot access it from your application (private API classes are subject to change without notice, hence the reason why Google does not let you access them).

Solution: just re-create the class in your application's package by copy/pasting the official source code from the link I provided. I've tried this, and it works fine (there's no reason why it shouldn't).

You can then add it to your preferences.xml like any other Preference. Example:

<com.example.myapp.YesNoPreference
    android:dialogMessage="Are you sure you want to revert all settings to their default values?"
    android:key="com.example.myapp.pref_reset_settings_key"
    android:summary="Revert all settings to their default values."
    android:title="Reset Settings" />

Which looks like this:

I just recently had this issue and I didn't even believe it was my mistype:

Array("Semester has been set as active!", true)
Array("Failed to set semester as active!". false)

And actually it was! I just accidentally typed "." rather than ","...

All modern browsers support a Map, which is a key/value data structure. There are a couple of reasons that make using a Map better than Object:

• An Object has a prototype, so there are default keys in the map.
• The keys of an Object are strings, where they can be any value for a Map.
• You can get the size of a Map easily while you have to keep track of size for an Object.

Example:

var myMap = new Map();

var keyObj = {},
    keyFunc = function () {},
    keyString = "a string";

myMap.set(keyString, "value associated with 'a string'");
myMap.set(keyObj, "value associated with keyObj");
myMap.set(keyFunc, "value associated with keyFunc");

myMap.size; // 3

myMap.get(keyString);    // "value associated with 'a string'"
myMap.get(keyObj);       // "value associated with keyObj"
myMap.get(keyFunc);      // "value associated with keyFunc"

If you want keys that are not referenced from other objects to be garbage collected, consider using a WeakMap instead of a Map.

You need to create a new Window class. You can design that then any way you want. You can create and show a window modally like this:

MyWindow popup = new MyWindow();
popup.ShowDialog();

You can add a custom property for your result value, or if you only have two possible results ( + possibly undeterminate, which would be null), you can set the window's DialogResult property before closing it and then check for it (it is the value returned by ShowDialog()).

Angular elements (such as the root element of a directive) are jQuery [Lite] objects. This means we can register the event listener like so:

link($scope, $el) {
    const fileInputSelector = '.my-file-input'

    function setFile() {
        // access file via $el.find(fileInputSelector).get(0).files[0]
    }

    $el.on('change', fileInputSelector, setFile)
}

This is jQuery event delegation. Here, the listener is attached to the root element of the directive. When the event is triggered, it will bubble up to the registered element and jQuery will determine if the event originated on an inner element matching the defined selector. If it does, the handler will fire.

Benefits of this method are:

• the handler is bound to the $element which will be automatically cleaned up when the directive scope is destroyed.
• no code in the template
• will work even if the target delegate (input) has not yet been rendered when you register the event handler (such as when using ng-if or ng-switch)

Well your onclick function works absolutely fine its your this line
window.external.values(a.value, b.value, c.value, d.value, e.value);

window.external is object and has no method name values

<html>
    <head>
     <script type="text/javascript">
          function exportToForm(a,b,c,d,e) {
             // window.external.values(a.value, b.value, c.value, d.value, e.value);
          //use alert to check its working 
         alert("HELLO");
}
      </script>
    </head>
    <body>
      <img onclick="exportToForm('1.6','55','10','50','1');" src="China-Flag-256.png"/>

Run the ALTER USER command. Be sure to change password to a strong password of your choosing.

1. sudo mysql # Login to mysql`

2. Run the below command

   ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
   

Now you can access it by using the new password.

Here I present an alias based on Richard Hansen's answer (and Ben C's suggestion), but that I adapted to exclude tags. The alias should be fairly robust.

# For Git 1.22+
git config --global alias.only '!b=${1:-$(git branch --show-current)}; git log --oneline --graph "heads/$b" --not --exclude="$b" --branches --remotes #'
# For older Git:
git config --global alias.only '!b=${1:-$(git symbolic-ref -q --short HEAD)}; b=${b##heads/}; git log --oneline --graph "heads/$b" --not --exclude="$b" --branches --remotes #'

Example of use:

git only mybranch  # Show commits that are in mybranch ONLY
git only           # Show commits that are ONLY in current branch

Note that ONLY means commits that would be LOST (after garbage collection) if the given branch was deleted (excluding the effect of tags). The alias should work even if there is unfortunately a tag named mybranch (thanks to prefix heads/). Note also that no commits are shown if they are part of any remote branch (including upstream if any), in compliance with the definition of ONLY.

The alias shows the one-line history as a graph of the selected commits.

  a --- b --- c --- master
   \           \
    \           d
     \           \
      e --- f --- g --- mybranch (HEAD)
       \
        h --- origin/other

With example above, git only would show:

  * (mybranch,HEAD)
  * g
  |\
  | * d
  * f 

In order to include tags (but still excluding HEAD), the alias becomes (adapt as above for older Git):

git config --global alias.only '!b=${1:-$(git branch --show-current)};  git log --oneline --graph --all --not --exclude="refs/heads/$b" --exclude=HEAD --all #'

Or the variant that includes all the tags including HEAD (and removing current branch as default since it won't output anything):

git config --global alias.only '!git log --oneline --graph --all --not --exclude=\"refs/heads/$1\" --all #'

This last version is the only one that really satisfies the criteria commits-that-are-lost-if-given-branch-is-deleted, since a branch cannot be deleted if it is checked out, and no commit pointed by HEAD or any other tag will be lost. However the first two variants are more useful.

Finally, the alias does not work with remote branches (eg. git only origin/master). The alias must be modified, for instance:

git config --global alias.remote-only '!git log --oneline --graph "$1" --not --exclude="$1" --remotes --branches #'

Normally "app" is the root of your application -- have you tried app/path/to/assets/img.png?

System.out.println("Result Date is : "+date);

I have the almost the same situation as yours; that if the screen width is less than the my specified width it should hide the div. This is the jquery code I used that worked for me.

$(window).resize(function() {

  if ($(this).width() < 1024) {

    $('.divIWantedToHide').hide();

  } else {

    $('.divIWantedToHide').show();

    }

});

You can use following approach:

import org.apache.commons.codec.binary.Base64;

// Encode data on your side using BASE64
byte[] bytesEncoded = Base64.encodeBase64(str.getBytes());
System.out.println("encoded value is " + new String(bytesEncoded));

// Decode data on other side, by processing encoded data
byte[] valueDecoded = Base64.decodeBase64(bytesEncoded);
System.out.println("Decoded value is " + new String(valueDecoded));

Hope this answers your doubt.

This is clean and simple.

Regex.IsMatch(file, fileNamestr, RegexOptions.IgnoreCase)

1. Using the Property window

   Select form ? go to property window ? select "start position" ? select whatever the place you want.

   

2. Programmatically

   Form form1 = new Form(); form1.StartPosition = FormStartPosition.CenterScreen; form1.ShowDialog();

   Note: Do not directly call Form.CenterToScreen() from your code. Read here.

There are many ways to do it:
One way:

#mybox:hover {
   display:none;
}

Another way:

#mybox:hover {
   visibility: hidden;
}

Or you could just do:

#mybox:hover {
   background:transparent;
   color:transparent;
}

Creating a .bashrc file in your home directory also works. That way you don't have to copy your .bash_profile every time you install a new version of git bash.

A perfect 1/3 cannot exist in CSS with full cross browser support (anything below IE9). I personally would do: (It's not the perfect solution, but it's about as good as you'll get for all browsers)

#c1, #c2 {
    width: 33%;
}

#c3 {
    width: auto;
}

Your calculation is correct for DATE types, but if your values are timestamps, you should probably use EXTRACT (or DATE_PART) to be sure to get only the difference in full days;

EXTRACT(DAY FROM MAX(joindate)-MIN(joindate)) AS DateDifference

An SQLfiddle to test with. Note the timestamp difference being 1 second less than 2 full days.

Looks like E*Trade has an API now.

For access to historical data, I've found EODData to have reasonable prices for their data dumps. For side projects, I can't afford (rather don't want to afford) a huge subscription fee just for some data to tinker with.

Try this:

.countTable table tr td:first-child + td

You could also reiterate in order to style the others columns:

.countTable table tr td:first-child + td + td {...} /* third column */
.countTable table tr td:first-child + td + td + td {...} /* fourth column */
.countTable table tr td:first-child + td + td + td +td {...} /* fifth column */

I think the following makes a bit more sense for print strings in reverse, but maybe that's just me:

for char in reversed( myString ):  
  print( char, end = "" )

Just for readability created library ngx-if-empty-or-has-items it will check if an object, set, map or array is not empty. Maybe it will help somebody. It has the same functionality as ngIf (then, else and 'as' syntax is supported).

arrayOrObjWithData = ['1'] || {id: 1}

<h1 *ngxIfNotEmpty="arrayOrObjWithData">
  You will see it
</h1>

 or 
 // store the result of async pipe in variable
 <h1 *ngxIfNotEmpty="arrayOrObjWithData$ | async as obj">
  {{obj.id}}
</h1>

 or

noData = [] || {}
<h1 *ngxIfHasItems="noData">
   You will NOT see it
</h1>

Try this simple in one line of code:-

$data= json_decode( json_encode($data), true);

Hope it helps :)

I was also facing this issue but in a little different scenario.

Scenario:

param = 1

def param():
    .....
def func():
    if param:
        var = {passing a dict here}
        param(var)

It looks simple and a stupid mistake here, but due to multiple lines of codes in the actual code, it took some time for me to figure out that the variable name I was using was same as my function name because of which I was getting this error.

Changed function name to something else and it worked.

So, basically, according to what I understood, this error means that you are trying to use an integer as a function or in more simple terms, the called function name is also used as an integer somewhere in the code. So, just try to find out all occurrences of the called function name and look if that is being used as an integer somewhere.

I struggled to find this, so, sharing it here so that someone else may save their time, in case if they get into this issue.

Hope this helps!

Since new Date().toUTCString()returns a string like "Wed, 11 Oct 2017 09:24:41 GMT" you can slice the last 3 characters and pass the sliced string to new Date():

new Date()
// Wed Oct 11 2017 11:34:33 GMT+0200 (CEST)

new Date(new Date().toUTCString().slice(0, -3))
// Wed Oct 11 2017 09:34:33 GMT+0200 (CEST)

The previous answers are quite complete regarding what :: method reference does. To sum up, it provides a way to refer to a method(or constructor) without executing it, and when evaluated, it creates an instance of the functional interface that provides the target type context.

Below are two examples to find an object with the max value in an ArrayList WITH and WITHOUT the use of :: method reference. Explanations are in the comments below.

WITHOUT the use of ::

import java.util.*;

class MyClass {
    private int val;
    MyClass (int v) { val = v; }
    int getVal() { return val; }
}

class ByVal implements Comparator<MyClass> {
    // no need to create this class when using method reference
    public int compare(MyClass source, MyClass ref) {
        return source.getVal() - ref.getVal();
    }
}

public class FindMaxInCol {
    public static void main(String args[]) {
        ArrayList<MyClass> myClassList = new ArrayList<MyClass>();
        myClassList.add(new MyClass(1));
        myClassList.add(new MyClass(0));
        myClassList.add(new MyClass(3));
        myClassList.add(new MyClass(6));

        MyClass maxValObj = Collections.max(myClassList, new ByVal());
    }
}

WITH the use of ::

import java.util.*;

class MyClass {
    private int val;
    MyClass (int v) { val = v; }
    int getVal() { return val; }
}

public class FindMaxInCol {
    static int compareMyClass(MyClass source, MyClass ref) {
        // This static method is compatible with the compare() method defined by Comparator. 
        // So there's no need to explicitly implement and create an instance of Comparator like the first example.
        return source.getVal() - ref.getVal();
    }

    public static void main(String args[]) {
        ArrayList<MyClass> myClassList = new ArrayList<MyClass>();
        myClassList.add(new MyClass(1));
        myClassList.add(new MyClass(0));
        myClassList.add(new MyClass(3));
        myClassList.add(new MyClass(6));

        MyClass maxValObj = Collections.max(myClassList, FindMaxInCol::compareMyClass);
    }
}

You're missing a GROUP BY clause:

SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.

If you wanna maintain the same order in your list, say: your Map looks like:

map.put(1, "msg1")
map.put(2, "msg2")
map.put(3, "msg3")

and you want your list looks like

["msg1", "msg2", "msg3"]   // same order as the map

you will have to iterate through the Map:

// sort your map based on key, otherwise you will get IndexOutofBoundException
Map<String, String> treeMap = new TreeMap<String, String>(map)

List<String> list = new List<String>();
for (treeMap.Entry<Integer, String> entry : treeMap.entrySet()) {
    list.add(entry.getKey(), entry.getValue());
}  

We have to do a project on college and we faced a very big problem, it is called Same Origin Policy. Amog other things, it makes that your XMLHttpRequest method from Javascript can't make requests to domains other than the domain that your site is on.

For example you can't make request to www.otherexample.com if your site is on www.example.com. JSONRequest allows that, but you will get result in JSON format if that site allows that(for example it has a web service that returns messages in JSON). That is one problem where you could use JSON perhaps.

Here is something practical: Yahoo JSON

<ListView android:id="@id/android:list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:drawSelectorOnTop="false"
        android:scrollbars="vertical"/>

When you run your application this way, the java excecutable read the MANIFEST inside your jar and find the main class you defined. In this class you have a static method called main. In this method you may use the command line arguments.

Here is my simplistic log4j2.xml that prints to console and writes to a daily rolling file:

// java
private static final Logger LOGGER = LogManager.getLogger(MyClass.class);

                <TimeBasedTriggeringPolicy interval="1" modulate="true" />

        </RollingFile>

            <AppenderRef ref="rollingFile" />
        </Root>
    </Loggers>
</Configuration>

TimeBasedTriggeringPolicy

interval (integer) - How often a rollover should occur based on the most specific time unit in the date pattern. For example, with a date pattern with hours as the most specific item and and increment of 4 rollovers would occur every 4 hours. The default value is 1.

modulate (boolean) - Indicates whether the interval should be adjusted to cause the next rollover to occur on the interval boundary. For example, if the item is hours, the current hour is 3 am and the interval is 4 then the first rollover will occur at 4 am and then next ones will occur at 8 am, noon, 4pm, etc.

A new log file will be created daily with previous day automatically renamed to:

cucumber_yyyy-MM-dd.log

In a Maven project, you would put the log4j2.xml in src/main/resources or src/test/resources.

Bitbucket: Check for Branch permissions in Settings (it may be on 'Deny all'). If that doesn't work, simply clone your branch to a new local branch, push the changes to the remote (a new remote branch will be created), and create a PR.

For Laravel 5.4+

'mobile_number_1' => 'required|numeric|min:0|regex:/^[789]\d{9}$/' should do the trick

=SUMPRODUCT( (MONTH($A$2:$A$6)=1) * ($B$2:$B$6) )

Explanation:

• (MONTH($A$2:$A$6)=1) creates an array of 1 and 0, it's 1 when the month is january, thus in your example the returned array would be [1, 1, 1, 0, 0]

• SUMPRODUCT first multiplies each value of the array created in the above step with values of the array ($B$2:$B$6), then it sums them. Hence in your example it does this: (1 * 430) + (1 * 96) + (1 * 440) + (0 * 72.10) + (0 * 72.30)

This works also in OpenOffice and Google Spreadsheets

Work out the solution according to what you want...

There are two things that getResource/getResourceAsStream() will get from the class it is called on...

1. The class loader
2. The starting location

So if you do

this.getClass().getResource("foo.txt");

it will attempt to load foo.txt from the same package as the "this" class and with the class loader of the "this" class. If you put a "/" in front then you are absolutely referencing the resource.

this.getClass().getResource("/x/y/z/foo.txt")

will load the resource from the class loader of "this" and from the x.y.z package (it will need to be in the same directory as classes in that package).

Thread.currentThread().getContextClassLoader().getResource(name)

will load with the context class loader but will not resolve the name according to any package (it must be absolutely referenced)

System.class.getResource(name)

Will load the resource with the system class loader (it would have to be absolutely referenced as well, as you won't be able to put anything into the java.lang package (the package of System).

Just take a look at the source. Also indicates that getResourceAsStream just calls "openStream" on the URL returned from getResource and returns that.

In Microsoft Windows, you can go through by route -f command to delete your current Gateway, check route / ? for more advance option, like add / delete etc and also can write a batch to add route on specific time as well but if you need to delete IP cache, then you have the option to use arp command.

i would recommend using this:

  background-repeat:no-repeat;
  background-image: url(your file location here);
  background-size:cover;(will only work with css3)

hope it helps :D

And if this doesnt support your needs just say it: i can make a jquery for multibrowser support.

I used an authentication check followed by a sub called by a mediator class to the View (which also implements an authentication check) to write the password to the data class.

It's not a perfect solution; however, it remedied my problem of not being able to move the password.

There's a nice workaround for this in the sitepoint forums:

<div onclick="this.nextElementSibling.style.display='block'; this.style.display='none'">
   <img src="my_thumbnail.png" style="cursor:pointer" />
</div>
<div style="display:none">
    <!-- Embed code here -->
</div>

Note: To prevent having to click twice to make the video play, use autoplay=1 in the video embed code. It will start playing when the second div is displayed.

This is an old question, anyway today the best practice is by using Object.defineProperty

const object1 = {};

Object.defineProperty(object1, 'property1', {
  value: 42,
  writable: false
});

object1.property1 = 77;
// throws an error in strict mode

console.log(object1.property1);
// expected output: 42

The best and the easiest way, for me was this..

->Simply create a thread with Handler containing sleep().

private ImageView myImageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_shape_count); myImageView= (ImageView)findViewById(R.id.shape1);
    Animation myFadeInAnimation = AnimationUtils.loadAnimation(this, R.anim.fadein);
    myImageView.startAnimation(myFadeInAnimation);

    new Thread(new Runnable() {
        private Handler handler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                Log.w("hendler", "recived");
                    Animation myFadeOutAnimation = AnimationUtils.loadAnimation(getBaseContext(), R.anim.fadeout);
                    myImageView.startAnimation(myFadeOutAnimation);
                    myImageView.setVisibility(View.INVISIBLE);
            }
        };

        @Override
        public void run() {
            try{
                Thread.sleep(2000); // your fadein duration
            }catch (Exception e){
            }
            handler.sendEmptyMessage(1);

        }
    }).start();
}

Find root build.gradle file and add google maven repo inside allprojects tag

repositories {
        mavenLocal()
        mavenCentral()
        maven {                                  // <-- Add this
            url 'https://maven.google.com/' 
            name 'Google'
        }
    } 

It's better to use specific version instead of variable version

compile 'com.android.support:appcompat-v7:27.0.0'

If you're using Android Plugin for Gradle 3.0.0 or latter version

repositories {
      mavenLocal()
      mavenCentral()
      google()        //---> Add this
} 

and inject dependency in this way :

implementation 'com.android.support:appcompat-v7:27.0.0'

I always get in here, for this topic. I'll put my code in here so i (or other) can use it next time. (Phew hate to search into my repository code).

Add the permission:

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

Add receiver and service:

<receiver android:enabled="true" android:name=".BootUpReceiver"
    android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>
<service android:name="Launcher" />

Create class Launcher:

public class Launcher extends Service {
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        new AsyncTask<Service, Void, Service>() {

            @Override
            protected Service doInBackground(Service... params) {
                Service service = params[0];
                PackageManager pm = service.getPackageManager();
                try {
                    Intent target = pm.getLaunchIntentForPackage("your.package.id");
                    if (target != null) {
                        service.startActivity(target);
                        synchronized (this) {
                            wait(3000);
                        }
                    } else {
                        throw new ActivityNotFoundException();
                    }
                } catch (ActivityNotFoundException | InterruptedException ignored) {
                }
                return service;
            }

            @Override
            protected void onPostExecute(Service service) {
                service.stopSelf();
            }

        }.execute(this);

        return START_STICKY;
    }
}

Create class BootUpReceiver to do action after android reboot.

For example launch MainActivity:

public class BootUpReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent target = new Intent(context, MainActivity.class);  
        target.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(target);  
    }
}

You can do something like this,

  Dim lstOfStrings As New List(Of String) From {"Value1", "Value2", "Value3"}

Collection Initializers

Here is an easy way.

Open the connection window, click on the Server name dropdown, and hover over the connection string you want to delete, then press delete.

Chrome is preflighting the request to look for CORS headers. If the request is acceptable, it will then send the real request. If you're doing this cross-domain, you will simply have to deal with it or else find a way to make the request non-cross-domain. This is by design.

Unlike simple requests (discussed above), "preflighted" requests first send an HTTP request by the OPTIONS method to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests are preflighted like this since they may have implications to user data. In particular, a request is preflighted if:

It uses methods other than GET, HEAD or POST. Also, if POST is used to send request data with a Content-Type other than application/x-www-form-urlencoded, multipart/form-data, or text/plain, e.g. if the POST request sends an XML payload to the server using application/xml or text/xml, then the request is preflighted. It sets custom headers in the request (e.g. the request uses a header such as X-PINGOTHER)

Ref: AJAX in Chrome sending OPTIONS instead of GET/POST/PUT/DELETE?

If the binary is something more than a dll or something that can be edited directly like an image, or a blend file (and you don't need to trash/select one file or the other) a real merge would be some like:

I suggest searching for a diff tool oriented to what are your binary file, for example, there are some free ones for image files for example

• npm install -g imagediff IIRC from https://github.com/uber/image-diff
• or python https://github.com/kaikuehne/mirror.git
• there are others out there

and compare them.

If there is no diff tool out there for comparing your files, then if you have the original generator of the bin file (that is, there exist an editor for it... like blender 3d, you can then manually inspect those files, also see the logs, and ask the other person what you should include) and do output of the files with https://git-scm.com/book/es/v2/Git-Tools-Advanced-Merging#_manual_remerge

$ git show :1:hello.blend > hello.common.blend
$ git show :2:hello.blend > hello.ours.blend
$ git show :3:hello.blend > hello.theirs.blend

std::vector<CustomClass *> whatever(20000);

or:

std::vector<CustomClass *> whatever;
whatever.reserve(20000);

The former sets the actual size of the array -- i.e., makes it a vector of 20000 pointers. The latter leaves the vector empty, but reserves space for 20000 pointers, so you can insert (up to) that many without it having to reallocate.

At least in my experience, it's fairly unusual for either of these to make a huge difference in performance--but either can affect correctness under some circumstances. In particular, as long as no reallocation takes place, iterators into the vector are guaranteed to remain valid, and once you've set the size/reserved space, you're guaranteed there won't be any reallocations as long as you don't increase the size beyond that.

I've just had this happen to me - and (while it was not instantly obvious) it was due to Resharper (R#) being disabled during a licensing issue.

Enabling Resharper fixed this for me!

I was trying to copy Gmail Login. When you click on "Email or phone" and type something on it the label translatesY(-38px) and scales(0.75).
What I did:-

<input type='email' class='email' placeholder=' ' />

Then In my CSS

input:not(:placeholder-shown){
//put my styles here and I got the expected results
}

If you try it and find any problem. Please share it.

You can include this directly in your buttun. It works very well. I hope it'll be useful for you. onclick="setTimeout('location.href = ../../dashboard.xhtml;', 7000);"

You may take a look at the code and complement with the answers written here.

For building containers you obviously want to use one of the standard containers (such as a std::vector). But this is a perfect example of the things you need to consider when your object contains RAW pointers.

If your object has a RAW pointer then you need to remember the rule of 3 (now the rule of 5 in C++11).

• Constructor
• Destructor
• Copy Constructor
• Assignment Operator
• Move Constructor (C++11)
• Move Assignment (C++11)

This is because if not defined the compiler will generate its own version of these methods (see below). The compiler generated versions are not always useful when dealing with RAW pointers.

The copy constructor is the hard one to get correct (it's non trivial if you want to provide the strong exception guarantee). The Assignment operator can be defined in terms of the Copy Constructor as you can use the copy and swap idiom internally.

See below for full details on the absolute minimum for a class containing a pointer to an array of integers.

Knowing that it is non trivial to get it correct you should consider using std::vector rather than a pointer to an array of integers. The vector is easy to use (and expand) and covers all the problems associated with exceptions. Compare the following class with the definition of A below.

class A
{ 
    std::vector<int>   mArray;
    public:
        A(){}
        A(size_t s) :mArray(s)  {}
};

Looking at your problem:

A* arrayOfAs = new A[5];
for (int i = 0; i < 5; ++i)
{
    // As you surmised the problem is on this line.
    arrayOfAs[i] = A(3);

    // What is happening:
    // 1) A(3) Build your A object (fine)
    // 2) A::operator=(A const&) is called to assign the value
    //    onto the result of the array access. Because you did
    //    not define this operator the compiler generated one is
    //    used.
}

The compiler generated assignment operator is fine for nearly all situations, but when RAW pointers are in play you need to pay attention. In your case it is causing a problem because of the shallow copy problem. You have ended up with two objects that contain pointers to the same piece of memory. When the A(3) goes out of scope at the end of the loop it calls delete [] on its pointer. Thus the other object (in the array) now contains a pointer to memory that has been returned to the system.

The compiler generated copy constructor; copies each member variable by using that members copy constructor. For pointers this just means the pointer value is copied from the source object to the destination object (hence shallow copy).

The compiler generated assignment operator; copies each member variable by using that members assignment operator. For pointers this just means the pointer value is copied from the source object to the destination object (hence shallow copy).

So the minimum for a class that contains a pointer:

class A
{
    size_t     mSize;
    int*       mArray;
    public:
         // Simple constructor/destructor are obvious.
         A(size_t s = 0) {mSize=s;mArray = new int[mSize];}
        ~A()             {delete [] mArray;}

         // Copy constructor needs more work
         A(A const& copy)
         {
             mSize  = copy.mSize;
             mArray = new int[copy.mSize];

             // Don't need to worry about copying integers.
             // But if the object has a copy constructor then
             // it would also need to worry about throws from the copy constructor.
             std::copy(&copy.mArray[0],&copy.mArray[c.mSize],mArray);

         }

         // Define assignment operator in terms of the copy constructor
         // Modified: There is a slight twist to the copy swap idiom, that you can
         //           Remove the manual copy made by passing the rhs by value thus
         //           providing an implicit copy generated by the compiler.
         A& operator=(A rhs) // Pass by value (thus generating a copy)
         {
             rhs.swap(*this); // Now swap data with the copy.
                              // The rhs parameter will delete the array when it
                              // goes out of scope at the end of the function
             return *this;
         }
         void swap(A& s) noexcept
         {
             using std::swap;
             swap(this.mArray,s.mArray);
             swap(this.mSize ,s.mSize);
         }

         // C++11
         A(A&& src) noexcept
             : mSize(0)
             , mArray(NULL)
         {
             src.swap(*this);
         }
         A& operator=(A&& src) noexcept
         {
             src.swap(*this);     // You are moving the state of the src object
                                  // into this one. The state of the src object
                                  // after the move must be valid but indeterminate.
                                  //
                                  // The easiest way to do this is to swap the states
                                  // of the two objects.
                                  //
                                  // Note: Doing any operation on src after a move 
                                  // is risky (apart from destroy) until you put it 
                                  // into a specific state. Your object should have
                                  // appropriate methods for this.
                                  // 
                                  // Example: Assignment (operator = should work).
                                  //          std::vector() has clear() which sets
                                  //          a specific state without needing to
                                  //          know the current state.
             return *this;
         }   
 }

It is an implementation of Pythagorean theorem. Link: http://en.wikipedia.org/wiki/Pythagorean_theorem

For Firefox you can apply the CSS declaration "-moz-user-select" to "none". Check out their documentation, user-select.

It's a "preview" of the future "user-select" as they say, so maybe Opera or WebKit-based browsers will support that. I also recall finding something for Internet Explorer, but I don't remember what :).

Anyway, unless it's a specific situation where text-selecting makes some dynamic functionality fail, you shouldn't really override what users are expecting from a webpage, and that is being able to select any text they want.

ok, you may use substr in correlation to instr to find the starting position of your string

select 
  dbms_lob.substr(
       product_details, 
       length('NEW.PRODUCT_NO'), --amount
       dbms_lob.instr(product_details,'NEW.PRODUCT_NO') --offset
       ) 
from my_table
where dbms_lob.instr(product_details,'NEW.PRODUCT_NO')>=1;

The two snippets do different things, so it's not a matter of taste but a matter of what's the right behaviour in your context. Python documentation explains the difference, but here are some examples:

Exhibit A

class Foo:
  def __init__(self):
    self.num = 1

This binds num to the Foo instances. Change to this field is not propagated to other instances.

Thus:

>>> foo1 = Foo()
>>> foo2 = Foo()
>>> foo1.num = 2
>>> foo2.num
1

Exhibit B

class Bar:
  num = 1

This binds num to the Bar class. Changes are propagated!

>>> bar1 = Bar()
>>> bar2 = Bar()
>>> bar1.num = 2 #this creates an INSTANCE variable that HIDES the propagation
>>> bar2.num
1
>>> Bar.num = 3
>>> bar2.num
3
>>> bar1.num
2
>>> bar1.__class__.num
3

Actual answer

If I do not require a class variable, but only need to set a default value for my instance variables, are both methods equally good? Or one of them more 'pythonic' than the other?

The code in exhibit B is plain wrong for this: why would you want to bind a class attribute (default value on instance creation) to the single instance?

The code in exhibit A is okay.

If you want to give defaults for instance variables in your constructor I would however do this:

class Foo:
  def __init__(self, num = None):
    self.num = num if num is not None else 1

...or even:

class Foo:
  DEFAULT_NUM = 1
  def __init__(self, num = None):
    self.num = num if num is not None else DEFAULT_NUM

...or even: (preferrable, but if and only if you are dealing with immutable types!)

class Foo:
  def __init__(self, num = 1):
    self.num = num

This way you can do:

foo1 = Foo(4)
foo2 = Foo() #use default

Still, this can be done with the following steps:

1. send an https ajax request to your web-site (the same domain)

   jQuery.ajax({
       'url'      : '//same_domain.com/ajax_receiver.php',
       'type'     : 'get',
       'data'     : {'foo' : 'bar'},
       'success'  : function(response) {
           console.log('Successful request');
       }
   }).fail(function(xhr, err) {
       console.error('Request error');
   });
   

2. get ajax request, for example, by php, and make a CURL get request to any desired website via http.

   use linslin\yii2\curl;
   $curl = new curl\Curl();
   $curl->get('http://example.com');
   

Following works for me

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

I know this is a resolved old topic, but I just answered a similar question, and though my answer could help someone else as it covers other solution options:

Click events work a little differently on touch enabled devices. There is no mouse, so technically there is no click. According to this article - http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html - due to memory limitations, click events are only emulated and dispatched from anchor and input elements. Any other element could use touch events, or have click events manually initialized by adding a handler to the raw html element, for example, to force click events on list items:

$('li').each(function(){
    this.onclick = function() {}
});

Now click will be triggered by li, therefore can be listened by jQuery.

On your case, you could just change the listener to the anchor element as very well put by @mason81, or use a touch event on the li:

$('.menu').on('touchstart', '.publications', function(){
    $('#filter_wrapper').show();
});

Here is a fiddle with a few experiments - http://jsbin.com/ukalah/9/edit

INSERT INTO atable (x,y,z) VALUES ( NULL,NULL,NULL)

Double and double are identical.

For the reason, see http://www.yoda.arachsys.com/csharp/floatingpoint.html . In short: a double is not an exact type and a minute difference between "x" and "0.1" will throw it off.

There are three ways of defining things in Scala:

• def defines a method
• val defines a fixed value (which cannot be modified)
• var defines a variable (which can be modified)

Looking at your code:

def person = new Person("Kumar",12)

This defines a new method called person. You can call this method only without () because it is defined as parameterless method. For empty-paren method, you can call it with or without '()'. If you simply write:

person

then you are calling this method (and if you don't assign the return value, it will just be discarded). In this line of code:

person.age = 20

what happens is that you first call the person method, and on the return value (an instance of class Person) you are changing the age member variable.

And the last line:

println(person.age)

Here you are again calling the person method, which returns a new instance of class Person (with age set to 12). It's the same as this:

println(person().age)

The key to getting this to work is to tell sed to exclude what you don't want to be output as well as specifying what you do want.

string='This is a sample 123 text and some 987 numbers'
echo "$string" | sed -rn 's/[^[:digit:]]*([[:digit:]]+)[^[:digit:]]+([[:digit:]]+)[^[:digit:]]*/\1 \2/p'

This says:

• don't default to printing each line (-n)
• exclude zero or more non-digits
• include one or more digits
• exclude one or more non-digits
• include one or more digits
• exclude zero or more non-digits
• print the substitution (p)

In general, in sed you capture groups using parentheses and output what you capture using a back reference:

echo "foobarbaz" | sed 's/^foo\(.*\)baz$/\1/'

will output "bar". If you use -r (-E for OS X) for extended regex, you don't need to escape the parentheses:

echo "foobarbaz" | sed -r 's/^foo(.*)baz$/\1/'

There can be up to 9 capture groups and their back references. The back references are numbered in the order the groups appear, but they can be used in any order and can be repeated:

echo "foobarbaz" | sed -r 's/^foo(.*)b(.)z$/\2 \1 \2/'

outputs "a bar a".

If you have GNU grep (it may also work in BSD, including OS X):

echo "$string" | grep -Po '\d+'

or variations such as:

echo "$string" | grep -Po '(?<=\D )(\d+)'

The -P option enables Perl Compatible Regular Expressions. See man 3 pcrepattern or man 3 pcresyntax.

if re.search(r"\b(?<=\w)%s\b(?!\w)" % TEXTO, subject, re.IGNORECASE):

This will insert what is in TEXTO into the regex as a string.

For me the issue was with a dash "-" in the window name field. I removed the dashes and IE does not error out and in fact opens the window.

You can also have a look at this related question. That user reported that using a join provided better performance than using a sub query.

Not with an iterator.

For org.json.JSONArray, you can do:

for (int i = 0; i < arr.length(); i++) {
  arr.getJSONObject(i);
}

For javax.json.JsonArray, you can do:

for (int i = 0; i < arr.size(); i++) {
  arr.getJsonObject(i);
}

If your input always has a time zone of "zulu" ("Z" = UTC), then you can use DateTimeFormatter.ISO_INSTANT (implicitly):

final Instant parsed = Instant.parse(dateTime);

If time zone varies and has the form of "+01:00" or "+01:00:00" (when not "Z"), then you can use DateTimeFormatter.ISO_OFFSET_DATE_TIME:

DateTimeFormatter formatter = DateTimeFormatter.ISO_OFFSET_DATE_TIME;
final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter);

If neither is the case, you can construct a DateTimeFormatter in the same manner as DateTimeFormatter.ISO_OFFSET_DATE_TIME is constructed.

Your current pattern has several problems:

• not using strict mode (ResolverStyle.STRICT);
• using yyyy instead of uuuu (yyyy will not work in strict mode);
• using 12-hour hh instead of 24-hour HH;
• using only one digit S for fractional seconds, but input has three.

I think this is what you are looking for? If you are looking to add a blur effect to a div element, you can do this directly through CSS Filters-- See fiddle: http://jsfiddle.net/ayhj9vb0/

 div {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
  width: 100px;
  height: 100px;
  background-color: #ccc;

}

Try this:

// MARK: Reload TableView

func reloadTableView(){

    tableView.reload()
}

It seems the answers here do not support an enterprise use case where a Nexus server has multiple users and has project-based isolation (protection) based on user id ALONG with using an automated build (CI) system like Jenkins. You would not be able to create a settings.xml file to satisfy the different user ids needed for different projects. I am not sure how to solve this, except by opening Nexus up to anonymous access for reading repositories, unless the projects could store a project-specific generic user id in their pom.xml.

Yes, on a 32bit machine the maximum amount of memory usable is around 4GB. Actually, depending on the OS it might be less due to parts of the address space being reserved: On Windows you can only use 3.5GB for example.

On 64bit you can indeed address 2^64 bytes of memory. Not that you'll ever have those - but then again, a long time ago the same thing was said about ever needing more than 640kb of memory...

Do you actually have the single quotes in your command? I don't think they are necessary. Plus, I think you also need --no-auth-cache and --non-interactive

Here is what I use (no single quotes)

--non-interactive --no-auth-cache --username XXXX --password YYYY

See the Client Credentials Caching documentation in the svnbook for more information.

You may need to repair your mdf file first using some tools. There are lot of tool available in the market. There is tool called SQL Database Recovery Tool Repairs which is very useful to repair the mdf files.

The issue might me because of corrupted transaction logs, you may use tool SQL Database Recovery Tool Repairs to repair your corrupted mdf file.

In Window in new version you can export like this

string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_');

Alternatively, to change all characters except numbers and letters, try:

string = string.replace(/[^a-zA-Z0-9]/g,'_');

KEYS pattern

Available since 1.0.0.

Time complexity: O(N) with N being the number of keys in the database, under the assumption that the key names in the database and the given pattern have limited length.

Returns all keys matching pattern.

Warning : This command is not recommended to use because it may ruin performance when it is executed against large databases instead of KEYS you can use SCAN or SETS.

Example of KEYS command to use :

redis> MSET firstname Jack lastname Stuntman age 35
"OK"
redis> KEYS *name*
1) "lastname"
2) "firstname"
redis> KEYS a??
1) "age"
redis> KEYS *
1) "lastname"
2) "age"
3) "firstname"

One thing that the above solutions don't take into account is if you have an array of inputs but only one value was supplied.

For instance, if the back end expects an array of People, but in this particular case, you are just dealing with a single person. Then doing:

<input type="hidden" name="People" value="Joe" />

Then with the previous solutions, it would just map to something like:

{
    "People" : "Joe"
}

But it should really map to

{
    "People" : [ "Joe" ]
}

To fix that, the input should look like:

<input type="hidden" name="People[]" value="Joe" />

And you would use the following function (based off of other solutions, but extended a bit)

$.fn.serializeObject = function() {
var o = {};
var a = this.serializeArray();
$.each(a, function() {
    if (this.name.substr(-2) == "[]"){
        this.name = this.name.substr(0, this.name.length - 2);
        o[this.name] = [];
    }

    if (o[this.name]) {
        if (!o[this.name].push) {
            o[this.name] = [o[this.name]];
        }
        o[this.name].push(this.value || '');
    } else {
        o[this.name] = this.value || '';
    }
});
return o;
};

This is my powershell newbie way of doing this

if ((Test-Path ".\Desktop\checkfile.txt") -ne "True") {
    Write-Host "Damn it"
} else {
    Write-Host "Yay"
}

You have to use the following code:

response.writeHead(302 , {
           'Location' : '/view/index.html' // This is your url which you want
        });
response.end();

The "proper" LaTeX ways to do it is to use a package which allows you to specify the spacing you want. There are several such package, and these two pages link to lists of them...

The href is probably generated in a javascript function. For example with jQuery:

$(function() {
    $('a.view').attr('href', 'http://www.google.com');
});

In case it is useful... I was hitting the "10 $digest() iterations reached. Aborting!" error when using $window.history.back(); with IE9 (works fine in other browsers of course).

I got it to work by using:

setTimeout(function() {
  $window.history.back();
},100);

This is an interesting question and since it isn't explained very explicitly in the documentation I'll answer this by going through the sourcecode of mod_rewrite; demonstrating a big benefit of open-source.

In the top section you'll quickly spot the defines used to name these flags:

#define CONDFLAG_NONE               1<<0
#define CONDFLAG_NOCASE             1<<1
#define CONDFLAG_NOTMATCH           1<<2
#define CONDFLAG_ORNEXT             1<<3
#define CONDFLAG_NOVARY             1<<4

and searching for CONDFLAG_ORNEXT confirms that it is used based on the existence of the [OR] flag:

else if (   strcasecmp(key, "ornext") == 0
         || strcasecmp(key, "OR") == 0    ) {
    cfg->flags |= CONDFLAG_ORNEXT;
}

The next occurrence of the flag is the actual implementation where you'll find the loop that goes through all the RewriteConditions a RewriteRule has, and what it basically does is (stripped, comments added for clarity):

# loop through all Conditions that precede this Rule
for (i = 0; i < rewriteconds->nelts; ++i) {
    rewritecond_entry *c = &conds[i];

    # execute the current Condition, see if it matches
    rc = apply_rewrite_cond(c, ctx);

    # does this Condition have an 'OR' flag?
    if (c->flags & CONDFLAG_ORNEXT) {
        if (!rc) {
            /* One condition is false, but another can be still true. */
            continue;
        }
        else {
            /* skip the rest of the chained OR conditions */
            while (   i < rewriteconds->nelts
                   && c->flags & CONDFLAG_ORNEXT) {
                c = &conds[++i];
            }
        }
    }
    else if (!rc) {
        return 0;
    }
}

You should be able to interpret this; it means that OR has a higher precedence, and your example indeed leads to if ( (A OR B) AND (C OR D) ). If you would, for example, have these Conditions:

RewriteCond A [or]
RewriteCond B [or]
RewriteCond C
RewriteCond D

it would be interpreted as if ( (A OR B OR C) and D ).

In other words, is there a better solution than needing to specify the format?

Yes, there is now (ie in late 2016), thanks to anytime::anydate from the anytime package.

See the following for some examples from above:

R> anydate(c("01 Jan 2000", "01/01/2000", "2015/10/10"))
[1] "2000-01-01" "2000-01-01" "2015-10-10"
R> 

As you said, these are in fact unambiguous and should just work. And via anydate() they do. Without a format.

You could avoid memory allocation. There are many variants, all having problems in case of multithreading environment.

I prefer this kind of implementation (actually, it is not correctly said I prefer, because I avoid singletons as much as possible):

class Singleton
{
private:
   Singleton();

public:
   static Singleton& instance()
   {
      static Singleton INSTANCE;
      return INSTANCE;
   }
};

It has no dynamic memory allocation.

A much neater way to get 'alternate constructors' is to use classmethods. For instance:

>>> class MyData:
...     def __init__(self, data):
...         "Initialize MyData from a sequence"
...         self.data = data
...     
...     @classmethod
...     def fromfilename(cls, filename):

The reason it's neater is that there is no doubt about what type is expected, and you aren't forced to guess at what the caller intended for you to do with the datatype it gave you. The problem with isinstance(x, basestring) is that there is no way for the caller to tell you, for instance, that even though the type is not a basestring, you should treat it as a string (and not another sequence.) And perhaps the caller would like to use the same type for different purposes, sometimes as a single item, and sometimes as a sequence of items. Being explicit takes all doubt away and leads to more robust and clearer code.
