you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)
cv2.imshow("Window", img)

If you look at the exception stack trace it says that, it failed to convert from ABDeadlineType to DeadlineType. Because your repository is going to return you the objects of ABDeadlineType. How the spring-data-jpa will convert into the other one(DeadlineType). You should return the same type from repository and then have some intermediate util class to convert it into your model class.

public interface ABDeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {
    List<ABDeadlineType> findAllSummarizedBy();
}

Pod is not started due to problem coming after initialization of POD.

Check and use command to get docker container of pod

docker ps -a | grep private-reg

Output will be information of docker container with id.

See docker logs:

docker logs -f <container id>

The output of ps aux looks like you did not start docker through systemd/systemctl.

It looks like you started it with:

sudo dockerd -H gridsim1103:2376

When you try to stop it with systemctl, nothing should happen as the resulting dockerd process is not controlled by systemd. So the behavior you see is expected.

The correct way to start docker is to use systemd/systemctl:

systemctl enable docker
systemctl start docker

After this, docker should start on system start.

EDIT: As you already have the docker process running, simply kill it by pressing CTRL+C on the terminal you started it. Or send a kill signal to the process.

The simple answer:

• doing a MOV RBX, 3 and MUL RBX is expensive; just ADD RBX, RBX twice

• ADD 1 is probably faster than INC here

• MOV 2 and DIV is very expensive; just shift right

• 64-bit code is usually noticeably slower than 32-bit code and the alignment issues are more complicated; with small programs like this you have to pack them so you are doing parallel computation to have any chance of being faster than 32-bit code

If you generate the assembly listing for your C++ program, you can see how it differs from your assembly.

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

I was facing the similar problem, but instead of one all of my pods were not ready and displaying Ready status 0/1 Something like

I tried a lot of things but at last i found that the context was not correctly set. Please use following command and ensure you are in correct context

kubectl config get-contexts

As @daniel-t points out in the comment: github.com/docker/docker/issues/2174 is about showing binding only to IPv6 in netstat, but that is not an issue. As that github issues states:

When setting up the proxy, Docker requests the loopback address '127.0.0.1', Linux realises this is an address that exists in IPv6 (as ::0) and opens on both (but it is formally an IPv6 socket). When you run netstat it sees this and tells you it is an IPv6 - but it is still listening on IPv4. If you have played with your settings a little, you may have disabled this trick Linux does - by setting net.ipv6.bindv6only = 1.

In other words, just because you see it as IPv6 only, it is still able to communicate on IPv4 unless you have IPv6 set to only bind on IPv6 with the net.ipv6.bindv6only setting. To be clear, net.ipv6.bindv6only should be 0 - you can run sysctl net.ipv6.bindv6only to verify.

the solution to this problem differs because each time you deploy the application will give you the same sentence or the problem is different, so you should see the tomcat server log for the exact problem.

It is not necessary to use System.Drawing to find the image format in a URI. System.Drawing is not available for .NET Core unless you download the System.Drawing.Common NuGet package and therefore I don't see any good cross-platform answers to this question.

Also, my example does not use System.Net.WebClient since Microsoft explicitly discourage the use of System.Net.WebClient.

We don't recommend that you use the WebClient class for new development. Instead, use the System.Net.Http.HttpClient class.

Download an image from a URL and write it to a file (cross platform)*

*Without old System.Net.WebClient and System.Drawing.

This method will asynchronously download an image (or any file as long as the URI has a file extension) using the System.Net.Http.HttpClient and then write it to a file, using the same file extension as the image had in the URI.

Getting the file extension

First part of getting the file extension is removing all the unnecessary parts from the URI.
We use Uri.GetLeftPart() with UriPartial.Path to get everything from the Scheme up to the Path.
In other words, https://www.example.com/image.png?query&with.dots becomes https://www.example.com/image.png.

After that, we use Path.GetExtension() to get only the extension (in my previous example, .png).

var uriWithoutQuery = uri.GetLeftPart(UriPartial.Path);
var fileExtension = Path.GetExtension(uriWithoutQuery);

Downloading the image

From here it should be straight forward. Download the image with HttpClient.GetByteArrayAsync, create the path, ensure the directory exists and then write the bytes to the path with File.WriteAllBytesAsync() (or File.WriteAllBytes if you are on .NET Framework)

private async Task DownloadImageAsync(string directoryPath, string fileName, Uri uri)
{
    using var httpClient = new HttpClient();

    // Get the file extension
    var uriWithoutQuery = uri.GetLeftPart(UriPartial.Path);
    var fileExtension = Path.GetExtension(uriWithoutQuery);

    // Create file path and ensure directory exists
    var path = Path.Combine(directoryPath, $"{fileName}{fileExtension}");
    Directory.CreateDirectory(directoryPath);

    // Download the image and write to the file
    var imageBytes = await _httpClient.GetByteArrayAsync(uri);
    await File.WriteAllBytesAsync(path, imageBytes);
}

Note that you need the following using directives.

using System;
using System.IO;
using System.Threading.Tasks;
using System.Net.Http;

Example usage

var folder = "images";
var fileName = "test";
var url = "https://cdn.discordapp.com/attachments/458291463663386646/592779619212460054/Screenshot_20190624-201411.jpg?query&with.dots";

await DownloadImageAsync(folder, fileName, new Uri(url));

Notes

• It's bad practice to create a new HttpClient for every method call. It is supposed to be reused throughout the application. I wrote a short example of an ImageDownloader(50 lines) with more documentation that correctly reuses the HttpClient and properly disposes of it that you can find here.

If you are using python3, you need to install python3-dev. This fixed my problem sudo apt-get install python3-dev.

Here's a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR

The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.

For example:

{ "things": ["a", "b", "c"] }

Would Unmarshal into a:

type Item struct {
    Things []string
}

And not into:

type Item struct {
    Things string
}

The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field -- "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int

Same Object Not Found problem here - both in Xampp as well as in Wamp. It turns out the root name of "phpmyadmin" was "PhpMyAdmin". I got rid of all the capitals, renaming the folder to "phpmyadmin", and after a couple of reloads phpmyadmin was working.

I found 2 reason for this issue:

1. Sometimes its because of multiple included libraries. For example you add

   compile 'com.nineoldandroids:library:2.4.0'

in your gradle and add another library that it also use "nineoldandroids" in it's gradle!

1. As Android Developer Official website said:

If you have built an Android app and received this error, then congratulations, you have a lot of code!

So, why?

The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65,536, including Android framework methods, library methods, and methods in your own code. Getting past this limit requires that you configure your app build process to generate more than one DEX file, known as a multidex configuration.

Then what should you do?

• Avoiding the 65K Limit - How?

  1. Review your app's direct and transitive dependencies - Ensure any large library dependency you include in your app is used in a manner that outweighs the amount of code being added to the application. A common anti-pattern is to include a very large library because a few utility methods were useful. Reducing your app code dependencies can often help you avoid the dex reference limit.
  2. Remove unused code with ProGuard - Configure the ProGuard settings for your app to run ProGuard and ensure you have shrinking enabled for release builds. Enabling shrinking ensures you are not shipping unused code with your APKs.
• Configuring Your App for Multidex with Gradle - How? 1.Change your Gradle build configuration to enable multidex.

put

multiDexEnabled true

in the defaultConfig, buildType, or productFlavor sections of your Gradle build file.

2.In your manifest add the MultiDexApplication class from the multidex support library to the application element.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
<application
    ...
    android:name="android.support.multidex.MultiDexApplication">
    ...
</application>
</manifest>

Note: If your app uses extends the Application class, you can override the attachBaseContext() method and call MultiDex.install(this) to enable multidex. For more information, see the MultiDexApplication reference documentation.

Also this code may help you:

dexOptions {
    javaMaxHeapSize "4g"
}

Put in your gradle(android{ ... } ).

In your application.properties file -

/src/main/resources/application.properties

Change the port number to something like this -

server.port=8181

Or alternatively you can provide alternative port number while executing your jar file - java -jar resource-server/build/libs/resource-server.jar --server.port=8888

One of the reasons for this error is the use of the jaxb implementation from the jdk. I am not sure why such a problem can appear in pretty simple xml parsing situations. You may use the latest version of the jaxb library from a public maven repository:

http://mvnrepository.com

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.2.12</version>
</dependency>

I would like to add another Bootstrap 4 solution. One that worked for me.

The CSS "Order" property, combined with a media query, can be used to re-order columns when they get stacked in smaller screens.

Something like this:

@media only screen and (max-width: 768px) {
    #first {
        order: 2;
    }
    #second {
        order: 4;
    }
    #third {
        order: 1;
    }
    #fourth {
        order: 3;
    }
}

CodePen Link: https://codepen.io/preston206/pen/EwrXqm

Adjust the screen size and you'll see the columns get stacked in a different order.

I'll tie this in with the original poster's question. With CSS, the navbar, sidebar, and content can be targeted and then order properties applied within a media query.

Roles View Model

public class RoleViewModel
{
    public string Id { get; set; }
    [Required(AllowEmptyStrings = false)]
    [Display(Name = "RoleName")]
    public string Name { get; set; }
}

Controller method

    [HttpPost]
    public async Task<ActionResult> Create(RoleViewModel roleViewModel)
    {
       if (ModelState.IsValid)
       {
           var role = new IdentityRole(roleViewModel.Name);
           var roleresult = await RoleManager.CreateAsync(role);
           if (!roleresult.Succeeded)
           {
               ModelState.AddModelError("", roleresult.Errors.First());
               return View();
           }
           return RedirectToAction("some_action");
       }
       return View();
    }

The problem is that solutions that work on regular angular select boxes do not work with Angular Material md-select and md-option using protractor. This one was posted by another, but it worked for me and I am unable to comment on his post yet (only 23 rep points). Also, I cleaned it up a bit, instead of browser.sleep, I used browser.waitForAngular();

element.all(by.css('md-select')).each(function (eachElement, index) {
    eachElement.click();                    // select the <select>
    browser.waitForAngular();              // wait for the renderings to take effect
    element(by.css('md-option')).click();   // select the first md-option
    browser.waitForAngular();              // wait for the renderings to take effect
});

In IIS7 with integrated mode, Current is not available in Application_Start. There is a similar thread here.

Here's a script (bash) to automate the first solution by @CodeGnome to restore from a backup (run from the top level of the corrupted repo). The backup doesn't need to be complete, it only needs to have the missing objects.

git fsck 2>&1 | grep -e missing -e invalid | awk '{print $NF}' | sort -u |
    while read entry; do
        mkdir -p .git/objects/${entry:0:2}
        cp ${BACKUP}/objects/${entry:0:2}/${entry:2} .git/objects/${entry:0:2}/${entry:2}
    done

To answer the underlying question of how to use a CASE expression in the WHERE clause:

First remember that the value of a CASE expression has to have a normal data type value, not a boolean value. It has to be a varchar, or an int, or something. It's the same reason you can't say SELECT Name, 76 = Age FROM [...] and expect to get 'Frank', FALSE in the result set.

Additionally, all expressions in a WHERE clause need to have a boolean value. They can't have a value of a varchar or an int. You can't say WHERE Name; or WHERE 'Frank';. You have to use a comparison operator to make it a boolean expression, so WHERE Name = 'Frank';

That means that the CASE expression must be on one side of a boolean expression. You have to compare the CASE expression to something. It can't stand by itself!

Here:

WHERE 
    DateDropped = 0
    AND CASE
            WHEN @JobsOnHold  = 1 AND DateAppr >= 0 THEN 'True'
            WHEN DateAppr != 0 THEN 'True'
            ELSE 'False'
        END = 'True'

Notice how in the end the CASE expression on the left will turn the boolean expression into either 'True' = 'True' or 'False' = 'True'.

Note that there's nothing special about 'False' and 'True'. You can use 0 and 1 if you'd rather, too.

You can typically rewrite the CASE expression into boolean expressions we're more familiar with, and that's generally better for performance. However, sometimes is easier or more maintainable to use an existing expression than it is to convert the logic.

The behavior of tintColor for bars has changed on iOS 7.0. It no longer affects the bar's background and behaves as described for the tintColor property added to UIView. To tint the bar's background, please use -barTintColor.

navController.navigationBar.barTintColor = [UIColor navigationColor];

There are two approaches to centering a column <div> in Bootstrap 3:

Approach 1 (offsets):

The first approach uses Bootstrap's own offset classes so it requires no change in markup and no extra CSS. The key is to set an offset equal to half of the remaining size of the row. So for example, a column of size 2 would be centered by adding an offset of 5, that's (12-2)/2.

In markup this would look like:

<div class="row">
    <div class="col-md-2 col-md-offset-5"></div>
</div>

Now, there's an obvious drawback for this method. It only works for even column sizes, so only .col-X-2, .col-X-4, col-X-6, col-X-8, and col-X-10 are supported.

Approach 2 (the old margin:auto)

You can center any column size by using the proven margin: 0 auto; technique. You just need to take care of the floating that is added by Bootstrap's grid system. I recommend defining a custom CSS class like the following:

.col-centered{
    float: none;
    margin: 0 auto;
}

Now you can add it to any column size at any screen size, and it will work seamlessly with Bootstrap's responsive layout:

<div class="row">
    <div class="col-lg-1 col-centered"></div>
</div>

Note: With both techniques you could skip the .row element and have the column centered inside a .container, but you would notice a minimal difference in the actual column size because of the padding in the container class.

Update:

Since v3.0.1 Bootstrap has a built-in class named center-block that uses margin: 0 auto, but is missing float:none, you can add that to your CSS to make it work with the grid system.

Turns out that the Eval.svc.cs needed its namespace changed to EvalServiceLibary, rather than EvalServiceSite.

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Basically, you use the /B and /C options:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

Here is my little utility helper for splitting paths int file, path tokens:

import os    
# usage: file, path = splitPath(s)
def splitPath(s):
    f = os.path.basename(s)
    p = s[:-(len(f))-1]
    return f, p

This works fine for me. Another way don't work good

                'ajax': {
                    complete: function (data) {
                        console.log(data['responseJSON']);
                    },
                    'url': 'xxx.php',
                },

This problem is solved, in my case, by encapsulating my jQuery in:

(function($) {
//my jquery 
})(jQuery);

First, create staticfiles folder. Inside that folder create css, js, and img folder.

settings.py

import os

PROJECT_DIR = os.path.dirname(__file__)

DATABASES = {
    'default': {
         'ENGINE': 'django.db.backends.sqlite3', 
         'NAME': os.path.join(PROJECT_DIR, 'myweblabdev.sqlite'),                        
         'USER': '',
         'PASSWORD': '',
         'HOST': '',                      
         'PORT': '',                     
    }
}

MEDIA_ROOT = os.path.join(PROJECT_DIR, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')

STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(PROJECT_DIR, 'staticfiles'),
)

main urls.py

from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from myweblab import settings

admin.autodiscover()

urlpatterns = patterns('',
    .......
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

urlpatterns += staticfiles_urlpatterns()

template

{% load static %}

<link rel="stylesheet" href="{% static 'css/style.css' %}">

You should bind the tap event, the click does not exist on mobile safari or in the UIWbview. You can also use this polyfill ,to avoid the 300ms delay when a link is touched.

Question 1: Unfortunately the one in which you you say is most intuitive is the least used in Android. As I understand, you should separate your UI (XML) and computational functionality (Java Class Files). It also makes for easier debugging. It is actually a lot easier to read this way and think about Android imo.

Question 2: I believe the two mainly used are #2 and #3. I will use a Button clickButton as an example.

2

is in the form of an anonymous class.

Button clickButton = (Button) findViewById(R.id.clickButton);
clickButton.setOnClickListener( new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                ***Do what you want with the click here***
            }
        });

This is my favorite as it has the onClick method right next to where the button variable was set with the findViewById. It seems very neat and tidy that everything that deals with this clickButton Button View is located here.

A con that my coworker comments, is that imagine you have many views that need onclick listener. You can see that your onCreate will get very long in length. So that why he likes to use:

3

Say you have, 5 clickButtons:

Make sure your Activity/Fragment implement OnClickListener

// in OnCreate

Button mClickButton1 = (Button)findViewById(R.id.clickButton1);
mClickButton1.setOnClickListener(this);
Button mClickButton2 = (Button)findViewById(R.id.clickButton2);
mClickButton2.setOnClickListener(this);
Button mClickButton3 = (Button)findViewById(R.id.clickButton3);
mClickButton3.setOnClickListener(this);
Button mClickButton4 = (Button)findViewById(R.id.clickButton4);
mClickButton4.setOnClickListener(this);
Button mClickButton5 = (Button)findViewById(R.id.clickButton5);
mClickButton5.setOnClickListener(this);


// somewhere else in your code

public void onClick(View v) {
    switch (v.getId()) {
        case  R.id.clickButton1: {
            // do something for button 1 click
            break;
        }

        case R.id.clickButton2: {
            // do something for button 2 click
            break;
        }

        //.... etc
    }
}

This way as my coworker explains is neater in his eyes, as all the onClick computation is handled in one place and not crowding the onCreate method. But the downside I see is, that the:

1. views themselves,
2. and any other object that might be located in onCreate used by the onClick method will have to be made into a field.

Let me know if you would like more information. I didn't answer your question fully because it is a pretty long question. And if I find some sites I will expand my answer, right now I'm just giving some experience.

The first argument of all methods is usually called self. It refers to the instance for which the method is being called.

Let's say you have:

class A(object):
    def foo(self):
        print 'Foo'

    def bar(self, an_argument):
        print 'Bar', an_argument

Then, doing:

a = A()
a.foo() #prints 'Foo'
a.bar('Arg!') #prints 'Bar Arg!'

There's nothing special about this being called self, you could do the following:

class B(object):
    def foo(self):
        print 'Foo'

    def bar(this_object):
        this_object.foo()

Then, doing:

b = B()
b.bar() # prints 'Foo'

In your specific case:

dangerous_device = MissileDevice(some_battery)
dangerous_device.move(dangerous_device.RIGHT) 

(As suggested in comments MissileDevice.RIGHT could be more appropriate here!)

You could declare all your constants at module level though, so you could do:

dangerous_device.move(RIGHT)

This, however, is going to depend on how you want your code to be organized!

I solved this by adding an using stament on top of my DBContext class, like so:

using SqlProviderServices= System.Data.Entity.SqlServer.SqlProviderServices;

I had this problem when building FFMPEG static libraries (e.g. libavcodec.a) for Android x86_64 target platform (using Android NDK clang). When statically linking with my library the problem occured although all FFMPEG C -> object files (*.o) were compiled with -fPIC compile option:

x86_64/libavcodec.a(h264_qpel_10bit.o): 
requires dynamic R_X86_64_PC32 reloc against 'ff_pw_1023' 
which may overflow at runtime; recompile with -fPIC

The problem occured only for libavcodec.a and libswscale.a.

Source of this problem is that FFMPEG has assembler optimizations for x86* platforms e.g. the reported problem cause is in libavcodec/h264_qpel_10bit.asm -> h264_qpel_10bit.o.

When producing X86-64 bit static library (e.g. libavcodec.a) it looks like assembler files (e.g. libavcodec/h264_qpel_10bit.asm) uses some x86 (32bit) assembler commands which are incompatible when statically linking with x86-64 bit target library since they don't support required relocation type.

Possible solutions:

1. compile all ffmpeg files with no assembler optimizations (for ffmpeg this is configure option: --disable-asm)
2. produce dynamic libraries (e.g. libavcodec.so) and link them in your final library dynamically

I chose 1) and it solved the problem.

Try adding "bDestroy": true to the options object literal, e.g.

$('#dataTable').dataTable({
    ...
    ....
    "bDestroy": true
});

Source: iodocs.com

or Remove the first:

$(document).ready(function() {
    $('#example').dataTable();
} );

In your case is the best option vjk.

selectedIndex is a JavaScript Select Property. For jQuery you can use this code:

jQuery(document).ready(function($) {
  $("#dropDownMenuKategorie").change(function() {
    // I personally prefer using console.log(), but if you want you can still go with the alert().
    console.log($(this).children('option:selected').index());
  });
});

I too was struggling with nested views in Angular.

Once I got a hold of ui-router I knew I was never going back to angular default routing functionality.

Here is an example application that uses multiple levels of views nesting

app.config(function ($stateProvider, $urlRouterProvider,$httpProvider) {
// navigate to view1 view by default
$urlRouterProvider.otherwise("/view1");

$stateProvider
    .state('view1', {
        url: '/view1',
        templateUrl: 'partials/view1.html',
        controller: 'view1.MainController'
    })
    .state('view1.nestedViews', {
        url: '/view1',
        views: {
            'childView1': { templateUrl: 'partials/view1.childView1.html' , controller: 'childView1Ctrl'},
            'childView2': { templateUrl: 'partials/view1.childView2.html', controller: 'childView2Ctrl' },
            'childView3': { templateUrl: 'partials/view1.childView3.html', controller: 'childView3Ctrl' }
        }
    })

    .state('view2', {
        url: '/view2',
    })

    .state('view3', {
        url: '/view3',
    })

    .state('view4', {
        url: '/view4',

});

As it can be seen there are 4 main views (view1,view2,view3,view4) and view1 has 3 child views.

try this css:

/* Show in default resolution screen*/
#container2 {
width: 960px;
position: relative;
margin:0 auto;
line-height: 1.4em;
}

/* If in mobile screen with maximum width 479px. The iPhone screen resolution is 320x480 px (except iPhone4, 640x960) */    
@media only screen and (max-width: 479px){
    #container2 { width: 90%; }
}

Here the demo: http://jsfiddle.net/ongisnade/CG9WN/

ALTER TABLE table_name ALTER COLUMN id SET DEFAULT uuid_in((md5((random())::text))::cstring);

After reading @ZuzEL's answer, i used the above code as the default value of the column id and it's working fine.

You have to set Connection property of Command object and use parametersized query instead of hardcoded SQL to avoid SQL Injection.

 using(SqlConnection openCon=new SqlConnection("your_connection_String"))
    {
      string saveStaff = "INSERT into tbl_staff (staffName,userID,idDepartment) VALUES (@staffName,@userID,@idDepartment)";

      using(SqlCommand querySaveStaff = new SqlCommand(saveStaff))
       {
         querySaveStaff.Connection=openCon;
         querySaveStaff.Parameters.Add("@staffName",SqlDbType.VarChar,30).Value=name;
         .....
         openCon.Open();

         querySaveStaff.ExecuteNonQuery();
       }
     }

To be concise and precise download the compatible jdbc (.jar) file compatible with your MySql version and put it in lib folder. For example for MySQL 8.0.2 download Connector/J 8.0.20

Even I faced the same issue - when checked on dashboard I found following Error. As the data was coming through Flume and had interrupted in between due to which may be there was inconsistency in few files.

Caused by: org.apache.hadoop.hive.serde2.SerDeException: org.codehaus.jackson.JsonParseException: Unexpected end-of-input within/between OBJECT entries

Running on fewer files it worked. Format consistency was the reason in my case.

You Log says, that you web.xml is malformed. Line 1, colum 7. It may be a UTF-8 Byte-Order-Marker

Try to verify, that your xml is wellformed and does not have a BOM. Java doesn't use BOMs.

array_shift the only parameter is an array passed by reference. The return value of explode(".", $value) does not have any reference. Hence the error.

You should store the return value to a variable first.

    $arr = explode(".", $value);
    $extension = strtolower(array_pop($arr));   
    $fileName = array_shift($arr);

From PHP.net

The following things can be passed by reference:

- Variables, i.e. foo($a)
- New statements, i.e. foo(new foobar())
- [References returned from functions][2]

No other expressions should be passed by reference, as the result is undefined. For example, the following examples of passing by reference are invalid:

I settled for the limitation (to some people a benefit) of having my rows only one line of text high. The CSS to contain long strings then becomes:

.datatable td {
  overflow: hidden; /* this is what fixes the expansion */
  text-overflow: ellipsis; /* not supported in all browsers, but I accepted the tradeoff */
  white-space: nowrap;
}

[edit to add:] After using my own code and initially failing, I recognized a second requirement that might help people. The table itself needs to have a fixed layout or the cells will just keep trying to expand to accomodate contents no matter what. If DataTables styles or your own styles don't already do so, you need to set it:

table.someTableClass {
  table-layout: fixed
}

Now that text is truncated with ellipses, to actually "see" the text that is potentially hidden you can implement a tooltip plugin or a details button or something. But a quick and dirty solution is to use JavaScript to set each cell's title to be identical to its contents. I used jQuery, but you don't have to:

  $('.datatable tbody td').each(function(index){
    $this = $(this);
    var titleVal = $this.text();
    if (typeof titleVal === "string" && titleVal !== '') {
      $this.attr('title', titleVal);
    }
  });

DataTables also provides callbacks at the row and cell rendering levels, so you could provide logic to set the titles at that point instead of with a jQuery.each iterator. But if you have other listeners that modify cell text, you might just be better off hitting them with the jQuery.each at the end.

This entire truncation method will ALSO have a limitation you've indicated you're not a fan of: by default columns will have the same width. I identify columns that are going to be consistently wide or consistently narrow, and explicitly set a percentage-based width on them (you could do it in your markup or with sWidth). Any columns without an explicit width get even distribution of the remaining space.

That might seem like a lot of compromises, but the end result was worth it for me.

Graphically, the cron syntax for Quarz is (source):

+-------------------- second (0 - 59)
|  +----------------- minute (0 - 59)
|  |  +-------------- hour (0 - 23)
|  |  |  +----------- day of month (1 - 31)
|  |  |  |  +-------- month (1 - 12)
|  |  |  |  |  +----- day of week (0 - 6) (Sunday=0 or 7)
|  |  |  |  |  |  +-- year [optional]
|  |  |  |  |  |  |
*  *  *  *  *  *  * command to be executed 

So if you want to run a command every 30 minutes you can say either of these:

0 0/30 * * * * ?
0 0,30 * * * * ?

You can check crontab expressions using either of these:

• crontab.guru — (disclaimer: I am not related to that page at all, only that I find it very useful). This page uses UNIX style of cron that does not have seconds in it, while Spring does as the first field.
• Cron Expression Generator & Explainer - Quartz — cron formatter, allowing seconds also.

It's been a lot of times and there are lots of valid answers, but the following code block seems to work:

my_object = SqlAlchemyModel()
my_serializable_obj = my_object.__dict__
del my_serializable_obj["_sa_instance_state"]
print(jsonify(my_serializable_object))

I'm aware that this is not a perfect solution, nor as elegant as the others, however for those who want o quick fix, they might try this.

This is the right answer http://stackoverflow.com/questions/6990767/inject-bean-reference-into-a-quartz-job-in-spring/15211030#15211030. and will work for most of the folks. But if your web.xml does is not aware of all applicationContext.xml files, quartz job will not be able to invoke those beans. I had to do an extra layer to inject additional applicationContext files

public class MYSpringBeanJobFactory extends SpringBeanJobFactory
        implements ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {

        try {
                PathMatchingResourcePatternResolver pmrl = new PathMatchingResourcePatternResolver(context.getClassLoader());
                Resource[] resources = new Resource[0];
                GenericApplicationContext createdContext = null ;
                    resources = pmrl.getResources(
                            "classpath*:my-abc-integration-applicationContext.xml"
                    );

                    for (Resource r : resources) {
                        createdContext = new GenericApplicationContext(context);
                        XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(createdContext);
                        int i = reader.loadBeanDefinitions(r);
                    }

            createdContext.refresh();//important else you will get exceptions.
            beanFactory = createdContext.getAutowireCapableBeanFactory();

        } catch (IOException e) {
            e.printStackTrace();
        }



    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle)
            throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        return job;
    }
}

You can add any number of context files you want your quartz to be aware of.

Yes, there are a number of ways that you can do this. The "fastest" way would be to add CSS to the div similar to the following

#term-defs {
height: 300px;
overflow: scroll; }

This will force the div to be scrollable, but this might not get the best effect. Another route would be to absolute fix the position of the items at the top, you can play with this by doing something like this.

#top {
  position: fixed;
  top: 0;
  left: 0;
  z-index: 999;
  width: 100%;
  height: 23px;
}

This will fix it to the top, on top of other content with a height of 23px.

The final implementation will depend on what effect you really want.

I have found a solution by myself. I use the PDANet tool to find the driver automatically.

In my case the sub domain name causes the problem. Here are details

I used app_development.something.com, here underscore(_) sub domain is creating CORS error. After changing app_development to app-development it works fine.

Here is a ES6 function that allows a min and a max and will generate an array of unique values in random order that contain all the number from min to max inclusive:

const createRandomNumbers = (min, max) => {
  const randomNumbers = new Set()
  const range = max - min + 1

  while (randomNumbers.size < range) {
    randomNumbers.add(~~(Math.random() * range))
  }

  return [...randomNumbers]
}

If your class extends JFrame then use this.setTitle(newTitle.getText());

If not and it contains a JFrame let's say named myFrame, then use myFrame.setTitle(newTitle.getText());

Now that you have posted your program, it is obvious that you need only one JTextField to get the new title. These changes will do the trick:

JTextField poolLengthText, poolWidthText, poolDepthText, poolVolumeText, hotTub,
        hotTubLengthText, hotTubWidthText, hotTubDepthText, hotTubVolumeText, temp, results,
        newTitle;

and:

    public void createOptions()
    {
        options = new JPanel();
        options.setLayout(null);
        JLabel labelOptions = new JLabel("Change Company Name:");
        labelOptions.setBounds(120, 10, 150, 20);
        options.add(labelOptions);
        newTitle = new JTextField("Some Title");
        newTitle.setBounds(80, 40, 225, 20);
        options.add(newTitle);
//        myTitle = new JTextField("My Title...");
//        myTitle.setBounds(80, 40, 225, 20);
//        myTitle.add(labelOptions);
        JButton newName = new JButton("Set New Name");
        newName.setBounds(60, 80, 150, 20);
        newName.addActionListener(this);
        options.add(newName);
        JButton Exit = new JButton("Exit");
        Exit.setBounds(250, 80, 80, 20);
        Exit.addActionListener(this);
        options.add(Exit);
    }

and:

private void New_Name()
{
    this.setTitle(newTitle.getText());
}

maybe there are some unmerged paths in your git repository that you have to resolve before stashing.

I just got my GUC232A cable with a molded-in PL2302 converter chip.

In addition to adding myself and br to group dialout, I found this helpful tip in the README.Debian file in /usr/share/doc/bottlerocket:

This package uses debconf to configure the /dev/firecracker symlink, should you need to change the symlink in the future run this command:

dpkg-reconfigure -pmedium bottlerocket

That will then prompt you for your new serial port and modify the symlink. This is required for proper use of bottlerocket.

I did that and voila! bottlerocket is able to communicate with my X-10 devices.

There are a bunch of different reasons for the "Too Many Connections" error.

Check out this FAQ page on MySQL.com: http://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html

Check your my.cnf file for "max_connections". If none exist try:

[mysqld]
set-variable=max_connections=250

However the default is 151, so you should be okay.

If you are on a shared host, it might be that other users are taking up too many connections.

Other problems to look out for is the use of persistent connections and running out of diskspace.

A 'fun' way to learn socket.io is to play BrowserQuest by mozilla and look at its source code :-)

as the exception says there is already another server running on the same port. you can either kill that service or change glassfish to run on another poet

Try float property. Here's an example: http://jsfiddle.net/mLmHR/

I think your problem is that String.split() treats its argument as a regex, and regexes treat newlines specially. You may need to explicitly create a regex object to pass to split() (there is another overload of it) and configure that regex to allow newlines by passing MULTILINE in the flags param of Pattern.compile().

base64 encode/decode example:

import base64

mystr = 'O João mordeu o cão!'

# Encode
mystr_encoded = base64.b64encode(mystr.encode('utf-8'))
# b'TyBKb8OjbyBtb3JkZXUgbyBjw6NvIQ=='

# Decode
mystr_encoded = base64.b64decode(mystr_encoded).decode('utf-8')
# 'O João mordeu o cão!'

I had the same problem (NetBeans 6.9.1) and the fix is so simple :)

I realized NetBeans didn't create a META-INF folder and thus no context.xml was found, so I create the META-INF folder under the main project folder and create file context.xml with the following content.

<?xml version="1.0" encoding="UTF-8"?>
    <Context antiJARLocking="true" path="/home"/>

And it runs :)

No, not exactly. But it can inherit from a class and implement one or more interfaces.

Clear terminology is important when discussing concepts like this. One of the things that you'll see mark out Jon Skeet's writing, for example, both here and in print, is that he is always precise in the way he decribes things.

Sorry, but it might even be more complicated, involving pbkdf2, or even a variation of it. Listen to the WWDC 2010 session #209, which mainly talks about the security measures in iOS 4, but also mentions briefly the separate encryption of backups and how they're related.

You can be pretty sure that without knowing the password, there's no way you can decrypt it, even by brute force.

Let's just assume you want to try to enable people who KNOW the password to get to the data of their backups.

I fear there's no way around looking at the actual code in iTunes in order to figure out which algos are employed.

Back in the Newton days, I had to decrypt data from a program and was able to call its decryption function directly (knowing the password, of course) without the need to even undersand its algorithm. It's not that easy anymore, unfortunately.

I'm sure there are skilled people around who could reverse engineer that iTunes code - you just have to get them interested.

In theory, Apple's algos should be designed in a way that makes the data still safe (i.e. practically unbreakable by brute force methods) to any attacker knowing the exact encryption method. And in WWDC session 209 they went pretty deep into details about what they do to accomplish this. Maybe you can actually get answers directly from Apple's security team if you tell them your good intentions. After all, even they should know that security by obfuscation is not really efficient. Try their security mailing list. Even if they do not repond, maybe someone else silently on the list will respond with some help.

Good luck!

Try this

select * 
from jobdetails 
where job_no between '0711' and '0713'

the only problem is that job '0713' is going to be returned as well so can use '07299999999999' or just add and job_no <> '0713'

I think the question is great and points out important perspectives and considerations.

With that said, I think the core of the question is in the intention and understanding what developer (you) wants to have controlled.

First, the name sleep is an overloaded naming choice. I.e., "what" is going to be "slept"; and "what" as a developer am I in control of?

In any language-engine, running on any OS process, on any bare-metal-or-hosted system the "developer" is NOT in control (owner) of the OS-shared-resource CPU core(s) [and/or threads] unless they are the writing the OS/Process system itself. CPUs are a time-shared resource, and the currency of work-execution progress are the "cycles" allocated amongst all work to be performed on the system.

As an app/service developer, it is best to consider that I am in control of a workflow-activity-stream managed by a os-process/language-engine. On some systems that means I control a native-os-thread (which likely shares CPU cores), on others it means I control an async-continuation-workflow chain/tree.

In the case of JavaScript, it is the "latter".

So when "sleep" is desired, I am intending to cause my workflow to be "delayed" from execution for some period of time, before it proceeds to execute the next "step" (phase/activity/task) in its workflow.

This is "appropriately" saying that as a developer it is easiest to (think in terms of) model work as a linear-code flow; resorting to compositions of workflows to scale as needed.

Today, in JavaScript, we have the option to design such linear work flows using efficient multi-tasking 1980s actor based continuation architectures (relabeled as modern Futures/Promises/then/await etc).

With that in mind, my answer is not contributing a new technical solution, but rather focusing on the intent and the design perspective within the question itself.

I suggest that any answer begins with thinking about the above concepts and then choosing a NAME (other than sleep) that reminds and suggests what the intention is.

Workflow

• Choice 1: delayWorkForMs(nMsToDelay)
• Choice 2: delayAsyncSequenceForMs(msPeriod)

async delayAsyncSequenceForMs(msPeriod) {
  await new Promise(resolve => setTimeout(resolve, msPeriod));
}

Keep in mind that any async function always returns a Promise, and await may only be used within an async function.
(lol, you might ask yourself why...).

• Consideration 1: do-not use "loops" to BURN UP cpu-cycles.
  
• Consideration 2: In the JavaScript model, when inside a non-async function you cannot "delay" (wait for) an "async" workflow's execution (unless you are doing bad things needlessly burning cpu cycles). You can only "delay" code-steps within an "async" function.
  Internally, an "async" function is modelled as a collection of entry-point/continuations at each await keyword. If you are familiar with the backtick interpolation model, you can "think of await" as being conceptually modelled similarly to writing a backquote string like:

  // Conceptualizing, using an interpolation example to illustrate
  // how to think about "await" and "async" functions
  `code${await then-restart-point}more-code${await then-restart-point}`

One options will be to show the selected option above (or below) the select list like following:

HTML

<div id="selText"><span>&nbsp;</span></div><br/>
<select size="4" id="mySelect" style="width:65px;color:#f98ad3;">
    <option value="1" selected>option 1 The Long Option</option>
    <option value="2">option 2</option>
    <option value="3">option 3</option>
    <option value="4">option 4</option>
    <option value="5">option 5 Another Longer than the Long Option ;)</option>
    <option value="6">option 6</option>
</select>

JavaScript

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"   
  type="text/javascript"></script> 
<script type="text/javascript">
$(document).ready(function(){        
    $("select#mySelect").change(function(){
      //$("#selText").html($($(this).children("option:selected")[0]).text());
       var txt = $($(this).children("option:selected")[0]).text();
       $("<span>" + txt + "<br/></span>").appendTo($("#selText span:last"));
    });
});
</script>

PS:- Set height of div#selText otherwise it will keep shifting select list downward.

I think the best way is to put your includes in your PHP include path. There are various ways to do this depending on your setup.

Then you can simply refer to

require_once 'inc1.php';

from inside any file regardless of where it is whether in your includes or in your web accessible files, or any level of nested subdirectories.

This allows you to have your include files outside the web server root, which is a best practice.

e.g.

site directory
    html (web root)
        your web-accessible files
    includes
        your include files

Also, check out __autoload for lazy loading of class files

http://www.google.com/search?q=setting+php+include+path

http://www.google.com/search?q=__autoload

I've just started listening to the irreverent Sod This podcast series, hosted by Gary Short and Oliver Sturm of DevExpress. They are fairly entertaining and mildly educational with a guest slot, slightly sweary though.

This will give you an array with 50 random numbers and display the smallest number in the array. I did it for an assignment in my programming class.

public static void main(String args[]) {
    // TODO Auto-generated method stub

    int i;
    int[] array = new int[50];
    for(i = 0; i <  array.length; i++) {
        array[i] = (int)(Math.random() * 100);
        System.out.print(array[i] + "  ");

        int smallest = array[0];

        for (i=1; i<array.length; i++)
        {
        if (array[i]<smallest)
        smallest = array[i];
        }



    }

}

}`

HSQLDB is a good candidate (the fact that it is used in OpenOffice may convinced some of you), but for such a small personnal application, why not using an object database (instead of a classic relationnal database) ?

I used DB4O in one of my projects, and I'm very satisfied with it. Being object-oriented, you don't need the whole Hibernate layer, and can directly insert/update/delete/query objects ! Moreover, you don't need to worry about the schema, you directly work with the objects and DB4O does the rest !

I agree that it may take some time to get used to this new type of database, but check the DB40 tutorial to see how easy it makes working with the DB !

EDIT: As said in the comments, DB4O handles automatically the newer versions of the classes. Moreover, a tool for browsing and updating the database outside of the application is available here : http://code.google.com/p/db4o-om/

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

Since in your question you said it's a PHP script, maybe the best solution could be to simply add in your script:

ignore_user_abort(TRUE);

In this way even if wget terminates, the PHP script goes on being processed at least until it does not exceeds max_execution_time limit (ini directive: 30 seconds by default).

As per wget anyay you should not change its timeout, according to the UNIX manual the default wget timeout is 900 seconds (15 minutes), whis is much larger that the 5-6 minutes you need.

A much faster implementation would be to use list-comprehension if you need to rename a single column.

df.columns = ['log(gdp)' if x=='gdp' else x for x in df.columns]

If the need arises to rename multiple columns, either use conditional expressions like:

df.columns = ['log(gdp)' if x=='gdp' else 'cap_mod' if x=='cap' else x for x in df.columns]

Or, construct a mapping using a dictionary and perform the list-comprehension with it's get operation by setting default value as the old name:

col_dict = {'gdp': 'log(gdp)', 'cap': 'cap_mod'}   ## key?old name, value?new name

df.columns = [col_dict.get(x, x) for x in df.columns]

Timings:

%%timeit
df.rename(columns={'gdp':'log(gdp)'}, inplace=True)
10000 loops, best of 3: 168 µs per loop

%%timeit
df.columns = ['log(gdp)' if x=='gdp' else x for x in df.columns]
10000 loops, best of 3: 58.5 µs per loop

It will be something like this:

SELECT b.Title, b.Edition, b.Year, b.Pages, b.Rating, c.Category, p.Publisher, w.LastName
FROM
    Books b
    JOIN Categories_Book cb ON cb._ISBN = b._Books_ISBN
    JOIN Category c ON c._CategoryID = cb._Categories_Category_ID
    JOIN Publishers p ON p._PublisherID = b.PublisherID
    JOIN Writers_Books wb ON wb._Books_ISBN = b._ISBN
    JOIN Writer w ON w._WritersID = wb._Writers_WriterID

You use the join statement to indicate which fields from table A map to table B. I'm using aliases here thats why you see Books b the Books table will be referred to as b in the rest of the query. This makes for less typing.

FYI your naming convention is very strange, I would expect it to be more like this:

Book: ID, ISBN , BookTitle, Edition, Year, PublisherID, Pages, Rating
Category: ID, [Name]
BookCategory: ID, CategoryID, BookID
Publisher: ID, [Name]
Writer: ID, LastName
BookWriter: ID, WriterID, BookID

If you want to convert back the file formats which have been changed to UNIX Format from PC format.

(1)You need to reinstall tortoise GIT and in the "Line Ending Conversion" Section make sure that you have selected "Check out as is - Check in as is"option.

(2)and keep the remaining configurations as it is.

(3)once installation is done

(4)write all the file extensions which are converted to UNIX format into a text file (extensions.txt).

ex:*.dsp
   *.dsw

(5) copy the file into your clone Run the following command in GITBASH

while read -r a;
do
find . -type f -name "$a" -exec dos2unix {} \;
done<extension.txt

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

You don't need to create the SSH keys on the Jenkins server, nor do you need to store the SSH keys on the Jenkins server's filesystem. This bit of information is crucial in environments where Jenkins servers instances may be created and destroyed frequently.

Generating the SSH Key Pair

On any machine (Windows, Linux, MacOS ...doesn't matter) generate an SSH key pair. Use this article as guide:

• GitHub: Generating a new SSH key and adding it to the ssh-agent (you can skip the section "Adding your SSH key to the ssh-agent")

On the Target Server

On the target server, you will need to place the content of the public key (id_rsa.pub per the above article) into the .ssh/authorized_keys file under the home directory of the user which Jenkins will be using for deployment.

In Jenkins

Using "Publish over SSH" Plugin

Ref: https://plugins.jenkins.io/publish-over-ssh/

Visit: Jenkins > Manage Jenkins > Configure System > Publish over SSH

• If the private key is encrypted, then you will need to enter the passphrase for the key into the "Passphrase" field, otherwise leave it alone.
• Leave the "Path to key" field empty as this will be ignored anyway when you use a pasted key (next step)
• Copy and paste the contents of the private key (id_rsa per the above article) into the "Key" field
• Under "SSH Servers", "Add" a new server configuration for your target server.

Using Stored Global Credentials

Visit: Jenkins > Credentials > System > Global credentials (unrestricted) > Add Credentials

• Kind: "SSH Username with private key"
• Scope: "Global"
• ID: [CREAT A UNIQUE ID FOR THIS KEY]
• Description: [optionally, enter a decription]
• Username: [USERNAME JENKINS WILL USE TO CONNECT TO REMOTE SERVER]
• Private Key: [select "Enter directly"]
• Key: [paste the contents of the private key (id_rsa per the above article)]
• Passphrase: [enter the passphrase for the key, or leave it blank if the key is not encrypted]

Add the following jars to the class path or lib folder

1. slf4j-api-1.7.2.jar
2. slf4j-jdk14-1.7.2.jar

This error happens when you have a __unicode__ method that is a returning a field that is not entered. Any blank field is None and Python cannot convert None, so you get the error.

In your case, the problem most likely is with the PCE model's __unicode__ method, specifically the field its returning.

You can prevent this by returning a default value:

def __unicode__(self):
   return self.some_field or u'None'

Minor addition to what has been said before. You likely want to return a dataframe. This would be done as

import pypyodbc 
import pandas as pd

cnxn = pypyodbc.connect("Driver={SQL Server Native Client 11.0};"
                        "Server=server_name;"
                        "Database=db_name;"
                        "uid=User;pwd=password")
df = pd.read_sql_query('select * from table', cnxn)

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.

In programmatically, add the background image

minSdkVersion 16

RadioGroup rg = new RadioGroup(this);
RadioButton radioButton = new RadioButton(this);
radioButton.setBackground(R.drawable.account_background);
rg.addView(radioButton);

What about this for a catch all...

if (string.IsNullOrEmpty(x.Trim())
{
}

This will trim all the spaces if they are there avoiding the performance penalty of IsWhiteSpace, which will enable the string to meet the "empty" condition if its not null.

I also think this is clearer and its generally good practise to trim strings anyway especially if you are putting them into a database or something.

You need a development provisioning profile on your build machine. Apps can run on the simulator without a profile, but they are required to run on an actual device.

If you open the project in Xcode, it may automatically set up provisioning for you. Otherwise you will have to create go to the iOS Dev Center and create a profile.

Another polyfill for element.classList is here. I found it via MDN.

I include that script and use element.classList.add("first","second","third") as it's intended.

With your own Code and a Slight Change withou jQuery,

function testingAPI(){ 
    var key = "8a1c6a354c884c658ff29a8636fd7c18"; 
    var url = "https://api.fantasydata.net/nfl/v2/JSON/PlayerSeasonStats/2015";
    console.log(httpGet(url,key)); 
}


function httpGet(url,key){
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", url, false );
    xmlHttp.setRequestHeader("Ocp-Apim-Subscription-Key",key);
    xmlHttp.send(null);
    return xmlHttp.responseText;
}

Thank You

ui-router doesn't track the previous state once it transitions, but the event $stateChangeSuccess is broadcast on the $rootScope when the state changes.

You should be able to catch the prior state from that event (from is the state you're leaving):

$rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
   //assign the "from" parameter to something
});

I had this problem when I had already installed ImageMagick with macports. I ran

    port contents ImageMagick | grep config

To find where the config file had been stored and then ran

    PATH=(insert your path here):${PATH} bundle

to install the gem using bundler. From now on, if you run a command that needs to reference ImageMagick, you can prefix it with that command. For example I had a migration that referenced it, so I ran

    PATH=/opt/local/bin/:${PATH} rake db:migrate

opt/local/bin/ is the path where my config file was stored.

LayoutInflater creates View objects based on layouts defined in XML. There are several different ways to use LayoutInflater, including creating custom Views, inflating Fragment views into Activity views, creating Dialogs, or simply inflating a layout file View into an Activity.

There are a lot of misconceptions about how the inflation process works. I think this comes from poor of the documentation for the inflate() method. If you want to learn about the inflate() method in detail, I wrote a blog post about it here:

https://www.bignerdranch.com/blog/understanding-androids-layoutinflater-inflate/

There are reasons beyond shipping for having an accurate postal code. Travel agencies doing tours that cross borders (Eurozone excepted of course) need this information ahead of time to give to the authorities. Often this information is entered by an agent that may or may not be familiar with such things. ANY method that can cut down on mistakes is a Good Idea™

However, writing a regex that would cover all postal codes in the world would be insane.

You need to call replace on z and not on str, since you want to replace characters located in the string variable z

removeSpecialChars = z.replace("!@#$%^&*()[]{};:,./<>?\|`~-=_+", " ")

But this will not work, as replace looks for a substring, you will most likely need to use regular expression module re with the sub function:

import re
removeSpecialChars = re.sub("[!@#$%^&*()[]{};:,./<>?\|`~-=_+]", " ", z)

Don't forget the [], which indicates that this is a set of characters to be replaced.

If you really want to get the type by name you may use the following:

System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");

Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.

Create an output file and custom function:

outputFile = open('outputfile.log', 'w')

def printing(text):
    print(text)
    if outputFile:
        outputFile.write(str(text))

Then instead of print(text) in your code, call printing function.

printing("START")
printing(datetime.datetime.now())
printing("COMPLETE")
printing(datetime.datetime.now())

or, we can use something like this

dim i = dgv1.CurrentCellAddress.X
dim j = dgv1.CurrentCellAddress.Y
MsgBox(dgv1.Item(i,j).Value.ToString())

In general, fixing corrupt objects can be pretty difficult. However, in this case, we're confident that the problem is an aborted transfer, meaning that the object is in a remote repository, so we should be able to safely remove our copy and let git get it from the remote, correctly this time.

The temporary object file, with zero size, can obviously just be removed. It's not going to do us any good. The corrupt object which refers to it, d4a0e75..., is our real problem. It can be found in .git/objects/d4/a0e75.... As I said above, it's going to be safe to remove, but just in case, back it up first.

At this point, a fresh git pull should succeed.

...assuming it was going to succeed in the first place. In this case, it appears that some local modifications prevented the attempted merge, so a stash, pull, stash pop was in order. This could happen with any merge, though, and didn't have anything to do with the corrupted object. (Unless there was some index cleanup necessary, and the stash did that in the process... but I don't believe so.)

1. If it is a library based only on javascript, than you can just run npm uninstall --save package_name or npm uninstall --save-dev package_name
2. If you've installed a library with native content that requires linking, and you've linked it with npm then you can do: npm unlink package_name then follow step 1
3. If you've installed a library with native content manually, then just undo all the steps you took to add the library in the first place. Then follow step 1.

note rnpm as is deprecated

As all of these comments are true, you should note that as far as ICANN approved Arabic (Persian) and Chinese characters to be registered as Domain Name, all of the browser-making companies (Microsoft, Mozilla, Apple, etc.) have to support Unicode in URLs without any encoding, and those should be searchable by Google, etc.

So this issue will resolve ASAP.

Here's an expansion on Michael Speer's answer to take it a few steps further:

An instance method decorator which takes arguments and acts on a function with arguments and a return value.

class Test(object):
    "Prints if x == y. Throws an error otherwise."
    def __init__(self, x):
        self.x = x

    def _outer_decorator(y):
        def _decorator(foo):
            def magic(self, *args, **kwargs) :
                print("start magic")
                if self.x == y:
                    return foo(self, *args, **kwargs)
                else:
                    raise ValueError("x ({}) != y ({})".format(self.x, y))
                print("end magic")
            return magic

        return _decorator

    @_outer_decorator(y=3)
    def bar(self, *args, **kwargs) :
        print("normal call")
        print("args: {}".format(args))
        print("kwargs: {}".format(kwargs))

        return 27

And then

    test = Test(3)
    test.bar(
        13,
        'Test',
        q=9,

Even though utf8_decode is a useful solution, I prefer to correct the encoding errors on the table itself. In my opinion it is better to correct the bad characters themselves than making "hacks" in the code. Simply do a replace on the field on the table. To correct the bad encoded characters from OP :

update <table> set <field> = replace(<field>, "ë", "ë")
update <table> set <field> = replace(<field>, "Ã", "à")
update <table> set <field> = replace(<field>, "ì", "ì")
update <table> set <field> = replace(<field>, "ù", "ù")

Where <table> is the name of the mysql table and <field> is the name of the column in the table. Here is a very good check-list for those typically bad encoded windows-1252 to utf-8 characters -> Debugging Chart Mapping Windows-1252 Characters to UTF-8 Bytes to Latin-1 Characters.

Remember to backup your table before trying to replace any characters with SQL!

[I know this is an answer to a very old question, but was facing the issue once again. Some old windows machine didnt encoded the text correct before inserting it to the utf8_general_ci collated table.]

Make all parent element with 100% width and 100% height and use display: table; and display:table-cell;, check the working sample.

If you are not already using the Jquery UI library and you want to mimic the effect what you can do is very simple

$('#blinkElement').fadeIn(100).fadeOut(100).fadeIn(100).fadeOut(100);

you can also play around with the numbers to get a faster or slower one to fit your design better.

This can also be a global jquery function so you can use the same effect across the site. Also note that if you put this code in a for loop you can have 1 milion pulses so therefore you are not restricted to the default 6 or how much the default is.

EDIT: Adding this as a global jQuery function

$.fn.Blink = function (interval = 100, iterate = 1) {
    for (i = 1; i <= iterate; i++)
        $(this).fadeOut(interval).fadeIn(interval);
}

Blink any element easily from your site using the following

$('#myElement').Blink(); // Will Blink once

$('#myElement').Blink(500); // Will Blink once, but slowly

$('#myElement').Blink(100, 50); // Will Blink 50 times once

You can do it using the fs-extra module very easily:

const fse = require('fs-extra');

let srcDir = 'path/to/file';
let destDir = 'pat/to/destination/directory';

fse.moveSync(srcDir, destDir, function (err) {

    // To move a file permanently from a directory
    if (err) {
        console.error(err);
    } else {
        console.log("success!");
    }
});

Or

fse.copySync(srcDir, destDir, function (err) {

     // To copy a file from a directory
     if (err) {
         console.error(err);
     } else {
         console.log("success!");
     }
});

Try setting startDate to the current date. For example:

$('.date-pick').datePicker({startDate:'01/01/1996'});

You can null/blank/space Etc value using LinQ Use Following Query

   var BlankValueRows = (from dr1 in Dt.AsEnumerable()
                                  where dr1["Columnname"].ToString() == ""
                                  || dr1["Columnname"].ToString() == ""
                                   || dr1["Columnname"].ToString() == ""
                                  select Columnname);

Here Replace Columnname with table column name and "" your search item in above code we looking null value.

You can compare an array like the below mentioned if the array has some values

it('should check if the array are equal', function() {
        var mockArr = [1, 2, 3];
        expect(mockArr ).toEqual([1, 2, 3]);
 });

But if the array that is returned from some function has more than 1 elements and all are zero then verify by using

expect(mockArray[0]).toBe(0);

Unfortunately, it is quite difficult to accomplish this with the arrow keys, due to restrictions in KeyDown events. However, there are a few ways to get around this:

• As @Snarfblam stated, you can override the ProcessCmdKey method, which retains the ability to parse arrow key presses.
• As the accepted answer from this question states, XNA has a built-in method called Keyboard.GetState(), which allows you to use arrow key inputs. However, WinForms doesn't have this, but it can be done through a P/Invoke, or by using a class that helps with it.

I recommend trying to use that class. It's quite simple to do so:

var left = KeyboardInfo.GetKeyState(Keys.Left);
var right = KeyboardInfo.GetKeyState(Keys.Right);
var up = KeyboardInfo.GetKeyState(Keys.Up);
var down = KeyboardInfo.GetKeyState(Keys.Down);

if (left.IsPressed)
{
//do something...
}

//etc...

If you use this in combination with the KeyDown event, I think you can reliably accomplish your goal.

These both work for me to clear the dropdown:

.select2('data', null)
.select2('val', null)

But important note: value doesn't get reset, .val() will return the first option even if it's not selected. I'm using Select2 3.5.3

To create a spreadsheet and format a cell using POI, see the Working with Fonts example, and use:

font.setBoldweight(Font.BOLDWEIGHT_BOLD);

POI works very well. There are some things you can't do (e.g. create VBA macros), but it'll read/write spreadsheets with macros, so you can create a suitable template sheet, read it and manipulate it with POI, and then write it out.

Since this question is quite old, but still comes up in google searches, I thought it would be good to point out the newer (and recommended) way to save Keras models. Instead of saving them using the older h5 format like has been shown before, it is now advised to use the SavedModel format, which is actually a dictionary that contains both the model configuration and the weights.

More information can be found here: https://www.tensorflow.org/guide/keras/save_and_serialize

The snippets to save & load can be found below:

model.fit(test_input, test_target)
# Calling save('my_model') creates a SavedModel folder 'my_model'.
model.save('my_model')

# It can be used to reconstruct the model identically.
reconstructed_model = keras.models.load_model('my_model')

A sample output of this :

Actually, you don't need to modify the object prototype and add a function there. The following should work well for your purpose.

var __next_objid=1;
function objectId(obj) {
    if (obj==null) return null;
    if (obj.__obj_id==null) obj.__obj_id=__next_objid++;
    return obj.__obj_id;
}

To make sure you get the call backs after the user enters text, set the delegate inside the configuration handler. textField.delegate = self

Swift 3 & 4 (iOS 10 - 11):

let alert = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.default, handler: nil))
alert.addTextField(configurationHandler: {(textField: UITextField!) in
    textField.placeholder = "Enter text:"
    textField.isSecureTextEntry = true // for password input
})
self.present(alert, animated: true, completion: nil)

In Swift (iOS 8-10):

override func viewDidAppear(animated: Bool) {
    var alert = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.Alert)
    alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.Default, handler: nil))
    alert.addTextFieldWithConfigurationHandler({(textField: UITextField!) in
        textField.placeholder = "Enter text:"
        textField.secureTextEntry = true
        })
    self.presentViewController(alert, animated: true, completion: nil)
}

In Objective-C (iOS 8):

- (void) viewDidLoad 
{
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Alert" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];
    [alert addAction:[UIAlertAction actionWithTitle:@"Click" style:UIAlertActionStyleDefault handler:nil]];
    [alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
        textField.placeholder = @"Enter text:";
        textField.secureTextEntry = YES;
    }];
    [self presentViewController:alert animated:YES completion:nil];
}

FOR iOS 5-7:

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"INPUT BELOW" delegate:self cancelButtonTitle:@"Hide" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];

NOTE: Below doesn't work with iOS 7 (iOS 4 - 6 Works)

Just to add another version.

- (void)viewDidLoad{

    UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Preset Saving..." message:@"Describe the Preset\n\n\n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
    UITextField *textField = [[UITextField alloc] init];
    [textField setBackgroundColor:[UIColor whiteColor]];
    textField.delegate = self;
    textField.borderStyle = UITextBorderStyleLine;
    textField.frame = CGRectMake(15, 75, 255, 30);
    textField.placeholder = @"Preset Name";
    textField.keyboardAppearance = UIKeyboardAppearanceAlert;
    [textField becomeFirstResponder];
    [alert addSubview:textField];

}

then I call [alert show]; when I want it.

The method that goes along

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {         
    NSString* detailString = textField.text;
    NSLog(@"String is: %@", detailString); //Put it on the debugger
    if ([textField.text length] <= 0 || buttonIndex == 0){ 
        return; //If cancel or 0 length string the string doesn't matter
    }
    if (buttonIndex == 1) {
        ...

    }
}

Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as:

public String loadJSONFromAsset(Context context) {
        String json = null;
        try {
            InputStream is = context.getAssets().open("file_name.json");

            int size = is.available();

            byte[] buffer = new byte[size];

            is.read(buffer);

            is.close();

            json = new String(buffer, "UTF-8");


        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
        return json;

    }

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html

Hope you will get what you want.

I also had a similar problem like yours. The problem is that you are using an old php version. I have upgraded to PHP 5.6 and the problem no longer exist.

Consider the following code with your current instruction pointer (the line that will be executed next, indicated by ->) at the f(x) line in g(), having been called by the g(2) line in main():

public class testprog {
    static void f (int x) {
        System.out.println ("num is " + (x+0)); // <- STEP INTO
    }

    static void g (int x) {
->      f(x); //
        f(1); // <----------------------------------- STEP OVER
    }

    public static void main (String args[]) {
        g(2);
        g(3); // <----------------------------------- STEP OUT OF
    }
}

If you were to step into at that point, you will move to the println() line in f(), stepping into the function call.

If you were to step over at that point, you will move to the f(1) line in g(), stepping over the function call.

Another useful feature of debuggers is the step out of or step return. In that case, a step return will basically run you through the current function until you go back up one level. In other words, it will step through f(x) and f(1), then back out to the calling function to end up at g(3) in main().

df <- data.frame(x=rnorm(10), y=rnorm(10))
rownames(df) <-  letters[1:10]
df[c('a','b'),]

Many solutions here, for me here's what worked.

1. I first changed the credentials from my Windows. In your Windows search, search "Credentials Manager", then go to "Windows Credentials", and updated (Edit option) my password to my new password. (Control Panel ? User Accounts ? Credential Manager for Visual Studio Git)

2. I restarted Visual Studio, and tried to push, but I still got the "Authentication failed error".

3. I went to back to the Windows Credential manager in step 1 and deleted(Remove option) the GIT account tied to my Visual Studio, I pushed again and it went through.

I find the above answers really lengthy, so to summarize:

The mysqli extension has a number of benefits, the key enhancements over the mysql extension being:

• Object-oriented interface
• Support for Prepared Statements
• Support for Multiple Statements
• Support for Transactions
• Enhanced debugging capabilities
• Embedded server support

Source: MySQLi overview

As explained in the above answers, the alternatives to mysql are mysqli and PDO (PHP Data Objects).

• API supports server-side Prepared Statements: Supported by MYSQLi and PDO
• API supports client-side Prepared Statements: Supported only by PDO
• API supports Stored Procedures: Both MySQLi and PDO
• API supports Multiple Statements and all MySQL 4.1+ functionality - Supported by MySQLi and mostly also by PDO

Both MySQLi and PDO were introduced in PHP 5.0, whereas MySQL was introduced prior to PHP 3.0. A point to note is that MySQL is included in PHP5.x though deprecated in later versions.

"Edit -> EOL Conversion". You can convert to Windows/Linux/Mac EOL there. The current format is displayed in the status bar.

Believe me I have tried a lot of options to do that and I have answer here

but I always look for the best practice and the best way I know so far for both front-end and back-end developers is for loop (yes I'm not kidding)

Because when the front-end gives you the UI Pages with dummy data he also added classes and some inline styles on specific select option so its hard to deal with using HtmlHelper

Take look at this :

<select class="input-lg" style="">
    <option value="0" style="color:#ccc !important;">
        Please select the membership name to be searched for
    </option>
    <option value="1">11</option>
    <option value="2">22</option>
    <option value="3">33</option>
    <option value="4">44</option>
</select>

this from the front-end developer so best solution is to use the for loop

fristly create or get your list of data from (...) in the Controller Action and put it in ViewModel, ViewBag or whatever

//This returns object that contain Items and TotalCount
ViewBag.MembershipList = await _membershipAppService.GetAllMemberships();

Secondly in the view do this simple for loop to populate the dropdownlist

<select class="input-lg" name="PrerequisiteMembershipId" id="PrerequisiteMembershipId">
    <option value="" style="color:#ccc !important;">
        Please select the membership name to be searched for
    </option>
    @foreach (var item in ViewBag.MembershipList.Items)
    {
        <option value="@item.Id" @(Model.PrerequisiteMembershipId == item.Id ? "selected" : "")>
            @item.Name
        </option>
    }
</select>

in this way you will not break UI Design, and its simple , easy and more readable

hope this help you even if you did not used razor

An excerpt from an apple technical note (Thanks to matthias-bauch)

Xcode includes all your command-line tools. If it is installed on your system, remove it to uninstall your tools.

If your tools were downloaded separately from Xcode, then they are located at /Library/Developer/CommandLineTools on your system. Delete the CommandLineTools folder to uninstall them.

you could easily delete using terminal:

Here is an article that explains how to remove the command line tools but do it at your own risk.Try this only if any of the above doesn't work.

Option 1) The quick and easy way (Toolbar only)

Since appcompat-v7-r23 you can use the following attributes directly on your Toolbar or its style:

app:titleTextColor="@color/primary_text"
app:subtitleTextColor="@color/secondary_text"

If your minimum SDK is 23 and you use native Toolbar just change the namespace prefix to android.

In Java you can use the following methods:

toolbar.setTitleTextColor(Color.WHITE);
toolbar.setSubtitleTextColor(Color.WHITE);

These methods take a color int not a color resource ID!

Option 2) Override Toolbar style and theme attributes

layout/xxx.xml

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:theme="@style/ThemeOverlay.MyApp.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    style="@style/Widget.MyApp.Toolbar.Solid"/>

values/styles.xml

<style name="Widget.MyApp.Toolbar.Solid" parent="Widget.AppCompat.ActionBar">
    <item name="android:background">@color/actionbar_color</item>
    <item name="android:elevation" tools:ignore="NewApi">4dp</item>
    <item name="titleTextAppearance">...</item>
</style>

<style name="ThemeOverlay.MyApp.ActionBar" parent="ThemeOverlay.AppCompat.ActionBar">
    <!-- Parent theme sets colorControlNormal to textColorPrimary. -->
    <item name="android:textColorPrimary">@color/actionbar_title_text</item>
</style>

Help! My icons changed color too!

@PeterKnut reported this affects the color of overflow button, navigation drawer button and back button. It also changes text color of SearchView.

Concerning the icon colors: The colorControlNormal inherits from

• android:textColorPrimary for dark themes (white on black)
• android:textColorSecondary for light themes (black on white)

If you apply this to the action bar's theme, you can customize the icon color.

<item name="colorControlNormal">#de000000</item>

There was a bug in appcompat-v7 up to r23 which required you to also override the native counterpart like so:

<item name="android:colorControlNormal" tools:ignore="NewApi">?colorControlNormal</item>

Help! My SearchView is a mess!

Note: This section is possibly obsolete.

Since you use the search widget which for some reason uses different back arrow (not visually, technically) than the one included with appcompat-v7, you have to set it manually in the app's theme. Support library's drawables get tinted correctly. Otherwise it would be always white.

<item name="homeAsUpIndicator">@drawable/abc_ic_ab_back_mtrl_am_alpha</item>

As for the search view text...there's no easy way. After digging through its source I found a way to get to the text view. I haven't tested this so please let me know in the comments if this didn't work.

SearchView sv = ...; // get your search view instance in onCreateOptionsMenu
// prefix identifier with "android:" if you're using native SearchView
TextView tv = sv.findViewById(getResources().getIdentifier("id/search_src_text", null, null));
tv.setTextColor(Color.GREEN); // and of course specify your own color

Bonus: Override ActionBar style and theme attributes

Appropriate styling for a default action appcompat-v7 action bar would look like this:

<!-- ActionBar vs Toolbar. -->
<style name="Widget.MyApp.ActionBar.Solid" parent="Widget.AppCompat.ActionBar.Solid">
    <item name="background">@color/actionbar_color</item> <!-- No prefix. -->
    <item name="elevation">4dp</item> <!-- No prefix. -->
    <item name="titleTextStyle">...</item> <!-- Style vs appearance. -->
</style>

<style name="Theme.MyApp" parent="Theme.AppCompat">
    <item name="actionBarStyle">@style/Widget.MyApp.ActionBar.Solid</item>
    <item name="actionBarTheme">@style/ThemeOverlay.MyApp.ActionBar</item>
    <item name="actionBarPopupTheme">@style/ThemeOverlay.AppCompat.Light</item>
</style>

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

As the error message says, non-default argument til should not follow default argument hgt.

Changing order of parameters (function call also be adjusted accordingly) or making hgt non-default parameter will solve your problem.

def a(len1, hgt=len1, til, col=0):

->

def a(len1, hgt, til, col=0):

UPDATE

Another issue that is hidden by the SyntaxError.

os.system accepts only one string parameter.

def a(len1, hgt, til, col=0):
    system('mode con cols=%s lines=%s' % (len1, hgt))
    system('title %s' % til)
    system('color %s' % col)

The code is

document.addEventListener('keydown', function(event){
    alert(event.keyCode);
} );

This return the ascii code of the key. If you need the key representation, use event.key (This will return 'a', 'o', 'Alt'...)

this type of error usually occur when you try to access data through the index in which data data has not been assign. for example

//assign of data in to array
for(int i=0; i<10; i++){
   arr[i]=i;
}
//accessing of data through array index
for(int i=10; i>=0; i--){
cout << arr[i];
}

the code will give error (vector subscript out of range) because you are accessing the arr[10] which has not been assign yet.

Keeping the emulator on top of all other task on the desktop and pressing "Ctrl + S", also captures the screen shot and it is saved on default(if, not edited) path(i.e. C:\Users\username\Desktop).

Or

you can just click on the "Camera" icon highlighted in "green", which we have with the emulator.

just try this in our style

white-space: normal;

this will solve, it will accept empty string or exact an email id

"^$|^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$"

You can use it to raise errors as part of error-checking:

if (a < b):
    raise ValueError()

Or handle some errors, and then pass them on as part of error-handling:

try:
    f = open('file.txt', 'r')
except IOError:
    # do some processing here
    # and then pass the error on
    raise

• Build solution will perform an incremental build: if it doesn't think it needs to rebuild a project, it won't. It may also use partially-built bits of the project if they haven't changed (I don't know how far it takes this)
• Rebuild solution will clean and then build the solution from scratch, ignoring anything it's done before. The difference between this and "Clean, followed by Build" is that Rebuild will clean-then-build each project, one at a time, rather than cleaning all and then building all.
• Clean solution will remove the build artifacts from the previous build. If there are any other files in the build target directories (bin and obj) they may not be removed, but actual build artifacts are. I've seen behaviour for this vary - sometimes deleting fairly thoroughly and sometimes not - but I'll give VS the benefit of the doubt for the moment :)

(The links are to the devenv.exe command line switches, but they do the same as the menu items.)

Increment a counter every time you render a screen and clear that counter for some time interval over which you want to measure the frame-rate.

Ie. Every 3 seconds, get counter/3 and then clear the counter.

you could use this formular to do the job -> get the CellValue for the specific row by typing: = indirect("$A&Cell()) depending on which column you have to check, you have to change the $A

For Example -> You could use a customized VBA Function in the Background:

Public Function IstDatum(Zelle) As Boolean IstDatum = False If IsDate(Zelle) Then IstDatum = True End Function

I need it to check for a date-entry in column A:

=IstDatum(INDIREKT("$A"&ZEILE()))

have a look at the picture:

Sorry for answering again on that question... I needed to embed the image.

I think the results @mice found are missleading. The observations might be correct for the font size of 60 but they turn much more different when the text is smaller. Eg. 10px. In that case the text is actually drawn BEYOND the bounds.

Sourcecode of the screenshot:

  @Override
  protected void onDraw( Canvas canvas ) {
    for( int i = 0; i < 20; i++ ) {
      int startSize = 10;
      int curSize = i + startSize;
      paint.setTextSize( curSize );
      String text = i + startSize + " - " + TEXT_SNIPPET;
      Rect bounds = new Rect();
      paint.getTextBounds( text, 0, text.length(), bounds );
      float top = STEP_DISTANCE * i + curSize;
      bounds.top += top;
      bounds.bottom += top;
      canvas.drawRect( bounds, bgPaint );
      canvas.drawText( text, 0, STEP_DISTANCE * i + curSize, paint );
    }
  }

Another way to break a string across multiple lines is to put an empty expression in the middle of the string, and break it across lines:

sample string:

"stackoverflow stackoverflow stackoverflow stackoverflow stackoverflow"

broken across lines:

"stackoverflow stackoverflow $(
)stackoverflow stack$(
)overflow stackoverflow"

Here is another try:

function stringToColor(str){
  var hash = 0;
  for(var i=0; i < str.length; i++) {
    hash = str.charCodeAt(i) + ((hash << 3) - hash);
  }
  var color = Math.abs(hash).toString(16).substring(0, 6);

  return "#" + '000000'.substring(0, 6 - color.length) + color;
}

df = mtcars 

dfnum = df[,-c(8,9)]

Thanks to codaddict for suggesting the -i option.

The following command solves the problem on Snow Leopard

sed -i '' -e's/[ \t]*$//' "$1"

You could wrap the work in a function and assign it to the Object prototype. Maybe use the fluent interface style to make multiple renames flow.

Object.prototype.renameProperty = function (oldName, newName) {
     // Do nothing if the names are the same
     if (oldName === newName) {
         return this;
     }
    // Check for the old property name to avoid a ReferenceError in strict mode.
    if (this.hasOwnProperty(oldName)) {
        this[newName] = this[oldName];
        delete this[oldName];
    }
    return this;
};

ECMAScript 5 Specific

I wish the syntax wasn't this complex but it is definitely nice having more control.

Object.defineProperty(
    Object.prototype, 
    'renameProperty',
    {
        writable : false, // Cannot alter this property
        enumerable : false, // Will not show up in a for-in loop.
        configurable : false, // Cannot be deleted via the delete operator
        value : function (oldName, newName) {
            // Do nothing if the names are the same
            if (oldName === newName) {
                return this;
            }
            // Check for the old property name to 
            // avoid a ReferenceError in strict mode.
            if (this.hasOwnProperty(oldName)) {
                this[newName] = this[oldName];
                delete this[oldName];
            }
            return this;
        }
    }
);

In order to create modular style sheets that are not dependent on the absolute location of a resource, authors may use relative URIs. Relative URIs (as defined in [RFC3986]) are resolved to full URIs using a base URI. RFC 3986, section 5, defines the normative algorithm for this process. For CSS style sheets, the base URI is that of the style sheet, not that of the source document.

For example, suppose the following rule:

body { background: url("yellow") }

is located in a style sheet designated by the URI:

http://www.example.org/style/basic.css

The background of the source document's BODY will be tiled with whatever image is described by the resource designated by the URI

http://www.example.org/style/yellow

User agents may vary in how they handle invalid URIs or URIs that designate unavailable or inapplicable resources.

Taken from the CSS 2.1 spec.

This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.

The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);  

As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.

Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:

The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null. In other words, leaving the anchor null ensures the tip points where it is supposed to point.

However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.

By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.

var pinShadow = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
    null,
    null,
    /* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
    new google.maps.Point(40, 110), 
    new google.maps.Size(120, 110)); 

to give this:

If you know that the Integer is not NULL, you can simply do this:

Integer intVal = 1;
Long longVal = (long) (int) intVal

To configure a message converter in plain spring-web, in this case to enable the Java 8 JSR-310 JavaTimeModule, you first need to implement WebMvcConfigurer in your @Configuration class and then override the configureMessageConverters method:

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    ObjectMapper objectMapper = Jackson2ObjectMapperBuilder.json().modules(new JavaTimeModule(), new Jdk8Module()).build()
            .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
    converters.add(new MappingJackson2HttpMessageConverter(objectMapper));
}

Like this you can register any custom defined ObjectMapper in a Java-based Spring configuration.

exitcode = data.wait(). The child process will be blocked If it writes to standard output/error, and/or reads from standard input, and there are no peers.

Use .col instead of col-lg-3 :

<div class="row">
   <div class="col">
      Fixed content
   </div>
   <div class="col-lg-9">
      Normal scrollable content
   </div>
</div>

In your code $this->uri->segment(3) refers to the pagination offset which you use in your query. According to your $config['base_url'] = base_url().'index.php/papplicant/viewdeletedrecords/' ;, $this->uri->segment(3) i.e segment 3 refers to the offset. The first segment is the controller, second is the method, there after comes the parameters sent to the controllers as segments.

You can use the query parameter ll for your lat and long, and you can use the query parameter q for what you want to search.

You can hide the "Watch Later" Button by using "Youtube-nocookie" (this will not hide the share Button)

Adding controls=0 will also remove the video control bar at the bottom of the screen and using modestbranding=1 will remove the youtube logo at bottom right of the screen

However using them both doesn't works as expected (it only hides the video control bar)

No.

From the cron man page:

...cron will then examine the modification time on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab file is modified

But if you just want to make sure its done anyway,

sudo service cron reload

or

/etc/init.d/cron reload

There are few things.

First, not /Graph but ./Graph

Second, when you use the TensorBoard callback, always pass validation data, because without it, it wouldn't start.

Third, if you want to use anything except scalar summaries, then you should only use the fit method because fit_generator will not work. Or you can rewrite the callback to work with fit_generator.

To add callbacks, just add it to model.fit(..., callbacks=your_list_of_callbacks)

You cannot set Referer header manually but you can use location.href to set the referer header to the link used in href but it will cause reloading of the page.

If you don't give an aspect argument to imshow, it will use the value for image.aspect in your matplotlibrc. The default for this value in a new matplotlibrc is equal. So imshow will plot your array with equal aspect ratio.

If you don't need an equal aspect you can set aspect to auto

imshow(random.rand(8, 90), interpolation='nearest', aspect='auto')

which gives the following figure

If you want an equal aspect ratio you have to adapt your figsize according to the aspect

fig, ax = subplots(figsize=(18, 2))
ax.imshow(random.rand(8, 90), interpolation='nearest')
tight_layout()

which gives you:

It seems you have found your solution, but still it will be helpful to others, on this page on point based on Chrome 59.

4.Note the red triangle in the top-right of the Animation Frame Fired event. Whenever you see a red triangle, it's a warning that there may be an issue related to this event.

If you hover on these triangle you can see those are the violation handler errors and as per point 4. yes there is some issue related to that event.

Since I searched a lot myself to serialize a Ruby Object to json:

require 'json'

class User
  attr_accessor :name, :age

  def initialize(name, age)
    @name = name
    @age = age
  end

  def as_json(options={})
    {
      name: @name,
      age: @age
    }
  end

  def to_json(*options)
    as_json(*options).to_json(*options)
  end
end

user = User.new("Foo Bar", 42)
puts user.to_json #=> {"name":"Foo Bar","age":42}

This method sucks, but I've left it here for reference so others avoid this path:

Using Option 1 from @ninjagecko worked best for me:

Array.prototype.equals = function(array) {
    return array instanceof Array && JSON.stringify(this) === JSON.stringify(array) ;
}

a = [1, [2, 3]]
a.equals([[1, 2], 3]) // false
a.equals([1, [2, 3]]) // true

It will also handle the null and undefined case, since we're adding this to the prototype of array and checking that the other argument is also an array.

I always have a primary key, even if in the beginning I don't have a purpose in mind yet for it. There have been a few times when I eventually need a PK in a table that doesn't have one and it's always more trouble to put it in later. I think there is more of an upside to always including one.

If you want to remove EVERYTHING :

textarea {
    border: none;
    background-color: transparent;
    resize: none;
    outline: none;
}

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

This works:

location.href.split(location.pathname)[0];

You could define the mainscreen and the other screen that you want to scroll up as fragments. When the button on the mainscreen is pushed, the fragment would send a message to the activity which would then replace the mainscreen with the one that you want to scroll up and animate the replacement.

I think this can be an easiest way to find a string in all rows of your database -without using cursors and FOR XML-.

CREATE PROCEDURE SPFindAll (@find VARCHAR(max) = '')
AS
BEGIN
    SET NOCOUNT ON;
    --
    DECLARE @query VARCHAR(max) = ''

    SELECT  @query = @query + 
            CASE 
                WHEN @query = '' THEN '' 
                ELSE ' UNION ALL '
            END +
            'SELECT ''' + s.name + ''' As schemaName, ''' + t.name + ''' As tableName, ''' + c.name + ''' As ColumnName, [' + c.name + '] COLLATE DATABASE_DEFAULT As [Data] FROM [' + s.name + '].[' + t.name + '] WHERE [' + c.name + '] Like ''%' + @find + '%'''
    FROM 
        sys.schemas s
        INNER JOIN
        sys.tables t ON s.[schema_id] = t.[schema_id]
        INNER JOIN 
        sys.columns c ON t.[object_id] = c.[object_id]
        INNER JOIN
        sys.types ty ON c.user_type_id = ty.user_type_id
    WHERE
        ty.name LIKE '%char'

    EXEC(@query)
END

By creating this stored procedure you can run it for any string you want to find like this:

EXEC SPFindAll 'Hello World'

The result will be like this:

schemaName | tableName | columnName | Data
-----------+-----------+------------+-----------------------
schema1    | Table1    | Column1    | Hello World
schema1    | Table1    | Column1    | Hello World!
schema1    | Table2    | Column1    | I say "Hello World".
schema1    | Table2    | Column2    | Hello World

Use the FileSystemObject object, namely, its CreateFolder and CopyFile methods. Basically, this is what your script will look like:

Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")

' Create a new folder
oFSO.CreateFolder "C:\MyFolder"

' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"

You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:

Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO

Set oFSO = CreateObject("Scripting.FileSystemObject")

If Not oFSO.FolderExists(strFolder) Then
  oFSO.CreateFolder strFolder
End If

oFSO.CopyFile strFile, strFolder, Overwrite

The default sqlite library that comes with iOS is not compiled using the SQLITE_THREADSAFE macro on. This could be a reason why your code crashes.

In short: this happens likely when you are hot-deploying webapps. For instance, your ide+development server hot-deploys a war again. Threads, that have been created previously are still running. But meanwhile their classloader/context is invalid and faces the IllegalAccessException / IllegalStateException becouse its orgininating webapp (the former runtime-environment) has been redeployed.

So, as states here, a restart does not permanently resolve this issue. Instead, it is better to find/implement a managed Thread Pool, s.th. like this to handle the termination of threads appropriately. In JavaEE you will use these ManagedThreadExeuctorServices. A similar opinion and reference here.

Examples for this are the EvictorThread of Apache Commons Pool, that "cleans" pooled instances according to the pool's configuration (max idle etc.).

raw_data['Mycol'] =  pd.to_datetime(raw_data['Mycol'], format='%d%b%Y:%H:%M:%S.%f')

works, however it results in a Python warning of A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead

I would guess this is due to some chaining indexing.

You need to add the following lines in your catalina.sh file.

export CATALINA_OPTS="-Xms512M -Xmx1024M"

UPDATE : catalina.sh content clearly says -

Do not set the variables in this script. Instead put them into a script setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

So you can add above in setenv.sh instead (create a file if it does not exist).

Reason to that is with the new update, they changed the URL for the Android Developer Tools update site to require HTTPS. If you are updating ADT, make sure you use HTTPS in the URL for the Android Developer Tools update site.

$this->db->or_where('end_date IS', 'NULL', false);

And I like this way:

$cars = array
  (
  array("Volvo",22),
  array("BMW",15),
  array("Saab",5),
  array("Land Rover",17)
  );

A TreeMap is probably the most straightforward way of doing this. You use it exactly like a normal Map. i.e.

Map<Float,String> mySortedMap = new TreeMap<Float,MyObject>();
// Put some values in it
mySortedMap.put(1.0f,"One");
mySortedMap.put(0.0f,"Zero");
mySortedMap.put(3.0f,"Three");

// Iterate through it and it'll be in order!
for(Map.Entry<Float,String> entry : mySortedMap.entrySet()) {
    System.out.println(entry.getValue());
} // outputs Zero One Three 

It's worth taking a look at the API docs, http://download.oracle.com/javase/6/docs/api/java/util/TreeMap.html to see what else you can do with it.

For those who are using Eclipse IDE.

After installing the full MySQL together with mysql client and mysql server and any mysql dev libraries,

You will need to tell Eclipse IDE about the following

• Where to find mysql.h
• Where to find libmysqlclient library
• The path to search for libmysqlclient library

Here is how you go about it.

To Add mysql.h

1. GCC C Compiler -> Includes -> Include paths(-l) then click + and add path to your mysql.h In my case it was /usr/include/mysql

To add mysqlclient library and search path to where mysqlclient library see steps 3 and 4.

2. GCC C Linker -> Libraries -> Libraries(-l) then click + and add mysqlcient

3. GCC C Linker -> Libraries -> Library search path (-L) then click + and add search path to mysqlcient. In my case it was /usr/lib64/mysql because I am using a 64 bit Linux OS and a 64 bit MySQL Database.

Otherwise, if you are using a 32 bit Linux OS, you may find that it is found at /usr/lib/mysql

try like this

var username= "<%= Session["UserName"]%>";

I want to make the very important note that the LINUX method using sendfile() has a major problem in that it can not copy files more than 2GB in size! I had implemented it following this question and was hitting problems because I was using it to copy HDF5 files that were many GB in size.

http://man7.org/linux/man-pages/man2/sendfile.2.html

sendfile() will transfer at most 0x7ffff000 (2,147,479,552) bytes, returning the number of bytes actually transferred. (This is true on both 32-bit and 64-bit systems.)

You can use GET instead of pass, but don't use this method for important values,

function passIDto(IDval){    
window.location.href = "CustomerBasket.php?oridd=" +  IDval ;
}   

In the CustomerBasket.php

<?php
  $value = $_GET["oridd"];
  echo  $value;
?>

Right, printf could be thought of as a more powerful version of puts. printf provides the ability to format variables for output using format specifiers such as %s, %d, %lf, etc...

In addition to adding these attributes to your Id column:

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public Guid Id { get; set; }

in your migration you should change your CreateTable to add the defaultValueSQL property to your column i.e.:

Id = c.Guid(nullable: false, identity: true, defaultValueSql: "newsequentialid()"),

This will prevent you from having to manually touch your database which, as you pointed out in the comments, is something you want to avoid with Code First.

You can have any length, but of course, there can be a memory issue on the computer if the String input is too long. The output is always 32 characters.

You refer to 'x' from window object

var x = 0;

function a(key, ref) {
    ref = ref || window;  // object reference - default window
    ref[key]++;
}

a('x');                   // string
alert(x);

WScript.exe exists in two versions, one in C:\Windows\System32\ and the other in C:\Windows\SysWOW64\ directories. They run respectively in 64 bits and 32 bits (against immediate logic but true).

You may add the following code at the beginning of your script so that it automatically starts again in 32 bits if it detects that it's called in 64 bits.

Note that it transmits the arguments if it calls itself to switch to 64 bits.

' C:\Windows\System32\WScript.exe = WScript.exe
Dim ScriptHost : ScriptHost = Mid(WScript.FullName, InStrRev(WScript.FullName, "\") + 1, Len(WScript.FullName))

Dim oWs : Set oWs = CreateObject("WScript.Shell")
Dim oProcEnv : Set oProcEnv = oWs.Environment("Process")

' Am I running 64-bit version of WScript.exe/Cscript.exe? So, call script again in x86 script host and then exit.
If InStr(LCase(WScript.FullName), LCase(oProcEnv("windir") & "\System32\")) And oProcEnv("PROCESSOR_ARCHITECTURE") = "AMD64" Then
    ' rebuild arguments
    If Not WScript.Arguments.Count = 0 Then
        Dim sArg, Arg
        sArg = ""
        For Each Arg In Wscript.Arguments
              sArg = sArg & " " & """" & Arg & """"
        Next
    End If

    Dim sCmd : sCmd = """" &  oProcEnv("windir") & "\SysWOW64\" & ScriptHost & """" & " """ & WScript.ScriptFullName & """" & sArg
    'WScript.Echo "Call " & sCmd
    oWs.Run sCmd
    WScript.Quit
End If

Short answer - yes, long answer: not how you want it.

You can use the %* form of printf, which accepts a variable width. And, if you use '0' as your value to print, combined with the right-aligned text that's zero padded on the left..

printf("%0*d\n", 20, 0);

produces:

00000000000000000000

With my tongue firmly planted in my cheek, I offer up this little horror-show snippet of code.

Some times you just gotta do things badly to remember why you try so hard the rest of the time.

#include <stdio.h>

int width = 20;
char buf[4096];

void subst(char *s, char from, char to) {
    while (*s == from)
    *s++ = to;
}

int main() {
    sprintf(buf, "%0*d", width, 0);
    subst(buf, '0', '-');
    printf("%s\n", buf);
    return 0;
}

When you use intellij also look at:

File -> Project Structure -> Project

File -> Project Structure -> Modules

When you have multiple modules make sure you set the correct language level in the module tab.

The easiest way is to use a StringContent, with the JSON representation of your JSON object.

httpClient.Post(
    "",
    new StringContent(
        myObject.ToString(),
        Encoding.UTF8,
        "application/json"));

You need to use the proper git URL:

pip install git+https://github.com/jkbr/httpie.git#egg=httpie

Also see the VCS Support section of the pip documentation.

Don’t forget to include the egg=<projectname> part to explicitly name the project; this way pip can track metadata for it without having to have run the setup.py script.

If you are using Spring

return new ResponseEntity<String>("your response", HttpStatus.ACCEPTED);

I had the same problem , first I couldn't find those dlls in the list of .NET components . but later I figured it out that the solution is :

1- first I changed target framework from .NET framework 4 client profile to .NET framework 4.

2- then scroll down the list of .NET components , pass first list of system.web... , scroll down , and find the second list of system.web... at the bottom , they're there .

I hope this could help others

Adding target="_blank" should do it:

<a id="myLink" href="www.google.com" target="_blank">google</a>

Deleting all instances of *.exd resolved it for me.

I can't think of a reason to explicitly lose precision outside of display purposes. In that case, simply use string formatting.

double example = 12.34567;

Console.Out.WriteLine(example.ToString("#.000"));

Here is another simple solution using np.histogram() method.

myarray = np.random.random(100)
results, edges = np.histogram(myarray, normed=True)
binWidth = edges[1] - edges[0]
plt.bar(edges[:-1], results*binWidth, binWidth)

You can indeed check that the total sums up to 1 with:

> print sum(results*binWidth)
1.0

match_parent and fill_parent are same property, used to define width or height of a view in full screen horizontally or vertically.

These properties are used in android xml files like this.

 android:layout_width="match_parent"
 android:layout_height="fill_parent"

or

 android:layout_width="fill_parent"
 android:layout_height="match_parent"

fill_parent was used in previous versions, but now it has been deprecated and replaced by match_parent. I hope it'll help you.

Indexes of two types can be added: when you define a primary key, MySQL will take it as index by default.

Explanation

Primary key as index

Consider you have a tbl_student table and you want student_id as primary key:

ALTER TABLE `tbl_student` ADD PRIMARY KEY (`student_id`)

Above statement adds a primary key, which means that indexed values must be unique and cannot be NULL.

Specify index name

ALTER TABLE `tbl_student` ADD INDEX student_index (`student_id`)

Above statement will create an ordinary index with student_index name.

Create unique index

ALTER TABLE `tbl_student` ADD UNIQUE student_unique_index (`student_id`)

Here, student_unique_index is the index name assigned to student_id and creates an index for which values must be unique (here null can be accepted).

Fulltext option

ALTER TABLE `tbl_student` ADD FULLTEXT student_fulltext_index (`student_id`)

Above statement will create the Fulltext index name with student_fulltext_index, for which you need MyISAM Mysql Engine.

How to remove indexes ?

DROP INDEX `student_index` ON `tbl_student`

How to check available indexes?

SHOW INDEX FROM `tbl_student`

After long research i understood that nothing is required for mac OS to install angular cli just use sudo npm install -g @angular/cli your terminal will prompt password enter your password it will proceed to install cli. It worked for me.

As I don't see here similar approach, and I'm not enjoying setting h/m/s/ms to 0, as it can cause problems with accurate transition to local time zone with changed date object (I presume so), let me introduce here this, written few moments ago, lil function:

+: Easy to use, makes a basic comparison operations done (comparing day, month and year without time.)
-: It seems that this is a complete opposite of "out of the box" thinking.

function datecompare(date1, sign, date2) {
    var day1 = date1.getDate();
    var mon1 = date1.getMonth();
    var year1 = date1.getFullYear();
    var day2 = date2.getDate();
    var mon2 = date2.getMonth();
    var year2 = date2.getFullYear();
    if (sign === '===') {
        if (day1 === day2 && mon1 === mon2 && year1 === year2) return true;
        else return false;
    }
    else if (sign === '>') {
        if (year1 > year2) return true;
        else if (year1 === year2 && mon1 > mon2) return true;
        else if (year1 === year2 && mon1 === mon2 && day1 > day2) return true;
        else return false;
    }    
}

Usage:

datecompare(date1, '===', date2) for equality check,
datecompare(date1, '>', date2) for greater check,
!datecompare(date1, '>', date2) for less or equal check

Also, obviously, you can switch date1 and date2 in places to achieve any other simple comparison.

It's best if you judge on your own,

Building off of Mamboking's answer:

ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(anyString())).thenReturn("Some result");

m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work(); 

Addressing your request to verify whether the argument contains a certain value, I could assume you mean that the argument is a String and you want to test whether the String argument contains a substring. For this you could do:

ArgumentCaptor<String> savedCaptor = ArgumentCaptor.forClass(String.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains("substring I want to find");

If that assumption was wrong, and the argument to save() is a collection of some kind, it would be only slightly different:

ArgumentCaptor<Collection<MyType>> savedCaptor = ArgumentCaptor.forClass(Collection.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains(someMyTypeElementToFindInCollection);

You might also check into ArgumentMatchers, if you know how to use Hamcrest matchers.

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

You can use // MARK:

There has also been discussion that liberal use of class extensions might be a better practice anyway. Since extensions can implement protocols, you can e.g. put all of your table view delegate methods in an extension and group your code at a more semantic level than #pragma mark is capable of.

You can use sklearn.preprocessing:

from sklearn.preprocessing import normalize
data = np.array([
    [1000, 10, 0.5],
    [765, 5, 0.35],
    [800, 7, 0.09], ])
data = normalize(data, axis=0, norm='max')
print(data)
>>[[ 1.     1.     1.   ]
[ 0.765  0.5    0.7  ]
[ 0.8    0.7    0.18 ]]

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

I have a Samsung Galaxy Tab 2 7.0 with Android 4.1.1. Apparently it does NOT sync to ntp. I loaded an app that says my tablet is 20 seconds off of ntp, but it can't set it unless I root the device.

Same problem but @Angelo answer didn't work for me, because I'm using same server with different credentials. I used the approach below and tested it on Windows 10.

cmdkey /add:server01 /user:<username> /pass:<password>

Then used mstsc /v:server01 to connect to the server.

The point is to use names instead of ip addresses to avoid conflict between credentials. If you don't have a DNS server locally accessible try c:\windows\system32\drivers\etc\hosts file.

If you're using ZLib in your project, then you need to find :

use SimpleDateFormat to first parse() String to Date and then format() Date to String

Alert boxes in JavaScript can only display pure text. You could use a JavaScript library like jQuery to display a modal instead?

This might be useful: http://jqueryui.com/dialog/

You can do it like this:

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8" />
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
  <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
  <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
  <script>
  body {
    font-family: "Trebuchet MS", "Helvetica", "Arial",  "Verdana", "sans-serif";
    font-size: 62.5%;
}

  </script>
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>
</head>
<body>

<div id="dialog" title="Basic dialog">
  <p>Image:</p>
  <img src="http://placehold.it/50x50" alt="Placeholder Image" />

</div>


</body>
</html>

I know it is an old question.

So this is what you have to do:

In you web.config file, add this in <system.web>:

<!-- 3GB Files / in kilobyte (3072*1024) -->
<httpRuntime targetFramework="4.5" maxRequestLength="3145728"/>

and this under <system.webServer>:

<security>
    <requestFiltering>

      <!-- 3GB Files / in byte (3072*1024*1024) -->
      <requestLimits maxAllowedContentLength="3221225472" />

    </requestFiltering>
</security>

You see in the comment how this works. In one you need to have the sie in bytes and in the other one in kilobytes. Hope that helps.

You want border-spacing:

<table style="border-spacing: 10px;">

Or in a CSS block somewhere:

table {
  border-spacing: 10px;
}

See quirksmode on border-spacing. Be aware that border-spacing does not work on IE7 and below.

It seems no one has mentioned a built-in factory method of producing ufunc in numpy package: np.frompyfunc which I have tested again np.vectorize and have outperformed it by about 20~30%. Of course it will perform well as prescribed C code or even numba(which I have not tested), but it can a better alternative than np.vectorize

f = lambda x, y: x * y
f_arr = np.frompyfunc(f, 2, 1)
vf = np.vectorize(f)
arr = np.linspace(0, 1, 10000)

%timeit f_arr(arr, arr) # 307ms
%timeit vf(arr, arr) # 450ms

I have also tested larger samples, and the improvement is proportional. See the documentation also here

You can with regular expressions Input Patterns (check browser compatibility)

<input id="password" name="password" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Must have at least 6 characters' : ''); if(this.checkValidity()) form.password_two.pattern = this.value;" placeholder="Password" required>

<input id="password_two" name="password_two" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Please enter the same Password as above' : '');" placeholder="Verify Password" required>

With classes you get inheritance and are passed by reference, structs do not have inheritance and are passed by value.

There are great WWDC sessions on Swift, this specific question is answered in close detail in one of them. Make sure you watch those, as it will get you up to speed much more quickly then the Language guide or the iBook.

This should do the trick:

pw_bytes.decode("utf-8")

What about this simple code, works for me and on Windows 7

set cntr=1
:begin
echo %cntr%
set /a cntr=%cntr%+1
if %cntr% EQU 1000 goto end
goto begin

:end

I know this question had been answered years ago, but for those like me who needed to change where the debugger starts the application, change the command property under Project Properties -> Debugging.

b = { 'video':0, 'music':23,"picture":12 } 
random.choice(tuple(b.items())) ('music', 23) 
random.choice(tuple(b.items())) ('music', 23) 
random.choice(tuple(b.items())) ('picture', 12) 
random.choice(tuple(b.items())) ('video', 0) 

If you happen to be using the Ruby gem redcarpet to render Markdown, you may still have this problem.

You can escape the numbering, and redcarpet will happily ignore any special meaning:

1\. Some heading

text text
text text

text text

2\. Some other heading

blah blah

more blah blah

You will need to do a couple of things to get this going, since your parameter is getting multiple values you need to create a Table Type and make your store procedure accept a parameter of that type.

Split Function Works Great when you are getting One String containing multiple values but when you are passing Multiple values you need to do something like this....

TABLE TYPE

CREATE TYPE dbo.TYPENAME AS TABLE   (     arg int    )  GO 

Stored Procedure to Accept That Type Param

 CREATE PROCEDURE mainValues   @TableParam TYPENAME READONLY  AS     BEGIN     SET NOCOUNT ON;   --Temp table to store split values   declare @tmp_values table (   value nvarchar(255) not null);        --function splitting values     INSERT INTO @tmp_values (value)    SELECT arg FROM @TableParam      SELECT * FROM @tmp_values  --<-- For testing purpose END 

EXECUTE PROC

Declare a variable of that type and populate it with your values.

 DECLARE @Table TYPENAME     --<-- Variable of this TYPE   INSERT INTO @Table                --<-- Populating the variable   VALUES (331),(222),(876),(932)  EXECUTE mainValues @Table   --<-- Stored Procedure Executed  

Result

╔═══════╗ ║ value ║ ╠═══════╣ ║   331 ║ ║   222 ║ ║   876 ║ ║   932 ║ ╚═══════╝ 

I don't think you can, the only other configuration alternative is to enumerate the paths that you want to be filtered, so instead of /* you could add some for /this/* and /that/* etc, but that won't lead to a sufficient solution when you have alot of those paths.

What you can do is add a parameter to the filter providing an expression (like a regular expression) which is used to skip the filter functionality for the paths matched. The servlet container will still call your filter for those url's but you will have better control over the configuration.

Edit

Now that you mention you have no control over the filter, what you could do is either inherit from that filter calling super methods in its methods except when the url path you want to skip is present and follow the filter chain like @BalusC proposed, or build a filter which instantiates your filter and delegates under the same circumstances. In both cases the filter parameters would include both the expression parameter you add and those of the filter you inherit from or delegate to.

The advantage of building a delegating filter (a wrapper) is that you can add the filter class of the wrapped filter as parameter and reuse it in other situations like this one.

When do we use AtomicReference?

AtomicReference is flexible way to update the variable value atomically without use of synchronization.

AtomicReference support lock-free thread-safe programming on single variables.

There are multiple ways of achieving Thread safety with high level concurrent API. Atomic variables is one of the multiple options.

Lock objects support locking idioms that simplify many concurrent applications.

Executors define a high-level API for launching and managing threads. Executor implementations provided by java.util.concurrent provide thread pool management suitable for large-scale applications.

Concurrent collections make it easier to manage large collections of data, and can greatly reduce the need for synchronization.

Atomic variables have features that minimize synchronization and help avoid memory consistency errors.

Provide a simple example where AtomicReference should be used.

Sample code with AtomicReference:

String initialReference = "value 1";

AtomicReference<String> someRef =
    new AtomicReference<String>(initialReference);

String newReference = "value 2";
boolean exchanged = someRef.compareAndSet(initialReference, newReference);
System.out.println("exchanged: " + exchanged);

Is it needed to create objects in all multithreaded programs?

You don't have to use AtomicReference in all multi threaded programs.

If you want to guard a single variable, use AtomicReference. If you want to guard a code block, use other constructs like Lock /synchronized etc.

You can import the module and check the module.__file__ string. It contains the path to the associated source file.

Alternatively, you can read the File tag in the the module documentation, which can be accessed using help(module), or module? in IPython.

A MySQL MyISAM table is the combination of three files:

• The FRM file is the table definition.
• The MYD file is where the actual data is stored.
• The MYI file is where the indexes created on the table are stored.

You should be able to restore by copying them in your database folder (In linux, the default location is /var/lib/mysql/)

You should do it while the server is not running.

You could use the Class.isInstance method:

if(!String.class.isInstance(str)) { /* do Something */ }

... but it is still negated and pretty ugly.

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

Depending on what you need each child for (if you're looking to post it somewhere via AJAX) you can just do...

$("#formID").serialize()

It creates a string for you with all of the values automatically.

As for looping through objects, you can also do this.

$.each($("input, select, textarea"), function(i,v) {
    var theTag = v.tagName;
    var theElement = $(v);
    var theValue = theElement.val();
});

Declarations of public functions go in header files, yes, but definitions are absolutely valid in headers as well! You may declare the definition as static (only 1 copy allowed for the entire program) if you are defining things in a header for utility functions that you don't want to have to define again in each c file. I.E. defining an enum and a static function to translate the enum to a string. Then you won't have to rewrite the enum to string translator for each .c file that includes the header. :)

Please note that the tr -s ' ' option will not remove any single leading spaces. If your column is right-aligned (as with ps pid)...

$ ps h -o pid,user -C ssh,sshd | tr -s " "
 1543 root
19645 root
19731 root

Then cutting will result in a blank line for some of those fields if it is the first column:

$ <previous command> | cut -d ' ' -f1

19645
19731

Unless you precede it with a space, obviously

$ <command> | sed -e "s/.*/ &/" | tr -s " "

Now, for this particular case of pid numbers (not names), there is a function called pgrep:

$ pgrep ssh

Shell functions

However, in general it is actually still possible to use shell functions in a concise manner, because there is a neat thing about the read command:

$ <command> | while read a b; do echo $a; done

The first parameter to read, a, selects the first column, and if there is more, everything else will be put in b. As a result, you never need more variables than the number of your column +1.

So,

while read a b c d; do echo $c; done

will then output the 3rd column. As indicated in my comment...

A piped read will be executed in an environment that does not pass variables to the calling script.

out=$(ps whatever | { read a b c d; echo $c; })

arr=($(ps whatever | { read a b c d; echo $c $b; }))
echo ${arr[1]}     # will output 'b'`

The Array Solution

So we then end up with the answer by @frayser which is to use the shell variable IFS which defaults to a space, to split the string into an array. It only works in Bash though. Dash and Ash do not support it. I have had a really hard time splitting a string into components in a Busybox thing. It is easy enough to get a single component (e.g. using awk) and then to repeat that for every parameter you need. But then you end up repeatedly calling awk on the same line, or repeatedly using a read block with echo on the same line. Which is not efficient or pretty. So you end up splitting using ${name%% *} and so on. Makes you yearn for some Python skills because in fact shell scripting is not a lot of fun anymore if half or more of the features you are accustomed to, are gone. But you can assume that even python would not be installed on such a system, and it wasn't ;-).

i am actually doing somewhat same thing but on my AWS S3 storage:-

Code for servlet which is receiving uploaded file:-

import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

        } catch(Exception e){
            System.out.println(e.getMessage());
        }
    }
}

                + "trying to communicate with S3, such as not being able to access the network.");

           result = result + ace.getMessage();
         }catch (Exception e) {
             result = result + e.getMessage();
       }

        return result;
    }
}

Note :- I am using aws properties file for credentials.

Hope this helps.

This answer fails in a couple of edge cases (see comments). The accepted solution above will handle these. str.splitlines() is the way to go. I will leave this answer nevertheless as reference.

Old (incorrect) answer:

s =  \
"""line1
line2
line3
"""

lines = s.split('\n')
print(lines)
for line in lines:
    print(line)

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).

The only difference would be if you try to reassign it before the end of this very file.

Lot of the information above led me to further research and ultimately my answer so I wanted to contribute what I wound up doing in hopes it helps someone else:

• I also wanted to pass a varied number of variables to a batch file so that they could be processed within the file.

• I was ok with passing them to the batch file using quotes

• I would want them processed similar to the below - but using a loop instead of writing out manually:

So I wanted to execute this:

prog_ZipDeleteFiles.bat "_appPath=C:\Services\Logs\PCAP" "_appFile=PCAP*.?"

And via the magic of for loops do this within the batch file:

set "_appPath=C:\Services\Logs\PCAP"
set "_appFile=PCAP*.?"

Problem I was having is that all my attempts to use a for loop weren't working. The below example:

for /f "tokens* delims= " in %%A (%*) DO (
   set %%A
)

would just do:

set "_appPath=C:\Services\Logs\PCAP"

and not:

set "_appPath=C:\Services\Logs\PCAP"
set "_appFile=PCAP*.?"

even after setting

SETLOCAL EnableDelayedExpansion

Reason was that the for loop read the whole line and assigned my second parameter to %%B during the first iteration of the loop. Because %* represents all arguments, there is only a single line to process - ergo only one pass of the for loop happens. This is by design it turns out, and my logic was wrong.

So I stopped trying to use a for loop and simplified what I was trying to do by using if, shift, and a goto statement. Agreed its a bit of a hack but it's more suited to my needs. I can loop through all of the arguments and then use an if statement to drop out of the loop once I process them all.

The winning statement for what I was trying to accomplish:

echo on
:processArguments
:: Process all arguments in the order received
if defined %1 then (
    set %1
    shift
    goto:processArguments
) ELSE (
    echo off 
)

UPDATE - I had to modify to the below instead, I was exposing all of the environment variables when trying to reference %1 and using shift in this manner:

echo on
shift
:processArguments
:: Process all arguments in the order received
if defined %0 then (
    set %0
    shift
    goto:processArguments
) ELSE (
    echo off 
)

Use

ls | % {(get-date) - $_.LastWriteTime }

It can work to retrieve the diff. You can replace ls with a single file.

Observer pattern is used when there is one-to-many relationship between objects such as if one object is modified, its dependent objects are to be notified automatically.

If you want to do it from the command line and not built into the script itself, use:

.\myscript.ps1 | Out-File c:\output.csv

You can use a regex:

if (/ST1/i.test(code))

You have to escape the backslash, so try this:

str = "Hello\\nWorld";

Here are more escaped characters in Javascript.

"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

https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS

If you have another column which is being used as foreign key or index then you have to specify that as well in the rule like this.

'phone' => [
                "required",
                "phone",
                Rule::unique('shops')->ignore($shopId, 'id')->where(function ($query) {
                    $query->where('user_id', Auth::id());
                }),
            ],

You can using the socket module to simply check if a port is open or not.

It would look something like this.

import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
   print "Port is open"
else:
   print "Port is not open"
sock.close()

You should separate out all the code that will do stuff from the service project into a separate project, and then make a test application that you can run and debug normally.

The service project would be just the shell needed to implement the service part of it.

Just download and install "Samsung Kies" from this link. and everything would work as required.

Before installing, uninstall the drivers you have installed for your device.

Update:

Two possible solutions:

1. Try with the Google USB driver which comes with the SDK.
2. Download and install the Samsung USB driver from this link as suggested by Mauricio Gracia Gutierrez

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );
              System.out.println("RECEIVED: " + sentence);
              // now send acknowledgement packet back to sender     
              DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length,
                   receivePacket.getAddress(), receivePacket.getPort());
              serverSocket.send(sendPacket);
        }
      } catch (IOException e) {
              System.out.println(e);
      }
      // should close serverSocket in finally block
    }
}

I was facing same issue with my one of my feature branch. I tried above mentioned solution nothing worked. I resolved this issue by doing following things.

• git pull origin feature-branch-name
• git push

This simple example for multidimensional array with function pointers":

void one( int a, int b){    printf(" \n[ ONE ]  a =  %d   b = %d",a,b);}
void two( int a, int b){    printf(" \n[ TWO ]  a =  %d   b = %d",a,b);}
void three( int a, int b){    printf("\n [ THREE ]  a =  %d   b = %d",a,b);}
void four( int a, int b){    printf(" \n[ FOUR ]  a =  %d   b = %d",a,b);}
void five( int a, int b){    printf(" \n [ FIVE ]  a =  %d   b = %d",a,b);}
void(*p[2][2])(int,int)   ;
int main()
{
    int i,j;
    printf("multidimensional array with function pointers\n");

    p[0][0] = one;    p[0][1] = two;    p[1][0] = three;    p[1][1] = four;
    for (  i  = 1 ; i >=0; i--)
        for (  j  = 0 ; j <2; j++)
            (*p[i][j])( (i, i*j);
    return 0;
}

Makes it easy to convert to and from Json objects.

Assuming the following method to test:

public boolean doSomething(SomeClass arg);

Mockito documentation says that you should not use captor in this way:

when(someObject.doSomething(argumentCaptor.capture())).thenReturn(true);
assertThat(argumentCaptor.getValue(), equalTo(expected));

Because you can just use matcher during stubbing:

when(someObject.doSomething(eq(expected))).thenReturn(true);

But verification is a different story. If your test needs to ensure that this method was called with a specific argument, use ArgumentCaptor and this is the case for which it is designed:

ArgumentCaptor<SomeClass> argumentCaptor = ArgumentCaptor.forClass(SomeClass.class);
verify(someObject).doSomething(argumentCaptor.capture());
assertThat(argumentCaptor.getValue(), equalTo(expected));

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2:Win32_Process")
objWMIService.Create "notepad.exe", null, null, intProcessID
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colMonitoredProcesses = objWMIService.ExecNotificationQuery _
    ("Select * From __InstanceDeletionEvent Within 1 Where TargetInstance ISA 'Win32_Process'")
Do Until i = 1
    Set objLatestProcess = colMonitoredProcesses.NextEvent
    If objLatestProcess.TargetInstance.ProcessID = intProcessID Then
        i = 1
    End If
Loop
Wscript.Echo "Notepad has been terminated."

I got this solution and it is working for me

if (myNewDT.MyDateTime == null)
{
   myNewDT.MyDateTime = DateTime.Now();
}

Empty strings are False by default:

>>> if not "":
...     print("empty")
...
empty

For Hadoop 3.x, if you try to create a file on HDFS when unauthenticated (e.g. user=dr.who) you will get this error.

It is not recommended for systems that need to be secure, however if you'd like to disable file permissions entirely in Hadoop 3 the hdfs-site.xml setting has changed to:

<property>
  <name>dfs.permissions.enabled</name>
  <value>false</value>
</property>

https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/hdfs-default.xml

The answer is really simple

// Your HTML text field

<input type="text" name="name" id="txt">

//Your javascript

<script type="text/javascript"> 
document.getElementById("txt").value = "My default value";
</script>

Or if you want to avoid JavaScript entirely: You can define it just using HTML

<input type="text" name="name" id="txt" value="My default value">

Some Android phones contain Busybox. Was hard to find.

To see if busybox was around:

ls -lR / | grep busybox

If you know it's around. You need some read/write space. Try you flash drive, /sdcard

cd /sdcard
ls -lR / >lsoutput.txt

upload to your computer. Upload the file. Get some text editor. Search for busybox. Will see what directory the file was found in.

busybox find /sdcard -iname 'python*'

to make busybox easier to access, you could:

cd /sdcard
ln -s /where/ever/busybox/is  busybox
/sdcard/busybox find /sdcard -iname 'python*'

Or any other place you want. R

<input type='text' minlength=3 /><br />

if browser supports html5,

it will automatical be validate attributes(minlength) in tag

but Safari(iOS) doesn't working

Most of these answers circulate around removing a file from the "staging area" pre-commit, but I often find myself looking here after I've already committed and I want to remove some sensitive information from the commit I just made.

An easy to remember trick for all of you git commit --amend folks out there like me is that you can:

1. Delete the accidentally committed file.
2. git add . to add the deletion to the "staging area"
3. git commit --amend to remove the file from the previous commit.

You will notice in the commit message that the unwanted file is now missing. Hooray! (Commit SHA will have changed, so be careful if you already pushed your changes to the remote.)

I don't think execute

 git rm first_file.txt

is a good idea.

1. when git notice your files is unmerged, you should ensure you had committed it.

2. And then open the conflict file:

   cat first_file.txt

3. fix the conflict

4.

git add file

git commit -m "fix conflict"

5. git push

it should works for you.

All other answers don't quite solve the issue. They print the date formatted as mm/dd/yyyy but the question was regarding MM/dd/yyyy. Notice the subtle difference? MM indicates that a leading zero must pad the month if the month is a single digit, thus having it always be a double digit number.

i.e. whereas mm/dd would be 3/31, MM/dd would be 03/31.

I've created a simple function to achieve this. Notice that the same padding is applied not only to the month but also to the day of the month, which in fact makes this MM/DD/yyyy:

function getFormattedDate(date) {_x000D_
  var year = date.getFullYear();_x000D_
_x000D_
  var month = (1 + date.getMonth()).toString();_x000D_
  month = month.length > 1 ? month : '0' + month;_x000D_
_x000D_
  var day = date.getDate().toString();_x000D_
  day = day.length > 1 ? day : '0' + day;_x000D_
  _x000D_
  return month + '/' + day + '/' + year;_x000D_
}

Update for ES2017 using String.padStart(), supported by all major browsers except IE.

function getFormattedDate(date) {_x000D_
    let year = date.getFullYear();_x000D_
    let month = (1 + date.getMonth()).toString().padStart(2, '0');_x000D_
    let day = date.getDate().toString().padStart(2, '0');_x000D_
  _x000D_
    return month + '/' + day + '/' + year;_x000D_
}

Use EntityScanner if you can bear external dependency.It will inject your all entity classes seamlessly even from multiple packages. Just add following line after configuration setup.

Configuration configuration = new Configuration().configure();    
EntityScanner.scanPackages("com.fz.epms.db.model.entity").addTo(configuration);
// And following depencency if you are using Maven
<dependency>
        <groupId>com.github.v-ladynev</groupId>
        <artifactId>fluent-hibernate-core</artifactId>
        <version>0.3.1</version>
</dependency>

This way you don't need to declare all entities in hibernate mapping file.
