Hello Thanks for the question; To resolve: "Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'"

In Windows Features check all for .NET 4 Advanced Services & .NET 3.5

Just like Nicolas Gago I tried aspnet_regiis.exe -iru but it didn't work. After the features were on then it yellow screen error was gone. Thanks;

you can use program like tcpview from sysinternal. I guess it can help you a lot on both monitoring and killing unwanted connection.

For convenience, you can create a wrapper class around ResultSet that returns null values when ResultSet ordinarily would not.

public final class ResultSetWrapper {

    private final ResultSet rs;

    public ResultSetWrapper(ResultSet rs) {
        this.rs = rs;
    }

    public ResultSet getResultSet() {
        return rs;
    }

    public Boolean getBoolean(String label) throws SQLException {
        final boolean b = rs.getBoolean(label);
        if (rs.wasNull()) {
            return null;
        }
        return b;
    }

    public Byte getByte(String label) throws SQLException {
        final byte b = rs.getByte(label);
        if (rs.wasNull()) {
            return null;
        }
        return b;
    }

    // ...

}

If title is not set, use 'ERROR' as default value.

More generic:

var foobar = foo || default;

Reads: Set foobar to foo or default. You could even chain this up many times:

var foobar = foo || bar || something || 42;

Here is a shortened version of the popular answer that gets the first letter by treating the string as an array:

function capitalize(s)
{
    return s[0].toUpperCase() + s.slice(1);
}

Update:

According to the comments below this doesn't work in IE 7 or below.

Update 2:

To avoid undefined for empty strings (see @njzk2's comment below), you can check for an empty string:

function capitalize(s)
{
    return s && s[0].toUpperCase() + s.slice(1);
}

One special case for this is if you have used a construction like the following in your ~/.muttrc:

# Reset From email to default
send-hook . "my_hdr From: Real Name <[email protected]>"

This send-hook will override either of these:

mutt -e "set [email protected]"
mutt -e "my_hdr From: Other Name <[email protected]>"

Your emails will still go out with the header:

From: Real Name <[email protected]>

In this case, the only command line solution I've found is actually overriding the send-hook itself:

mutt -e "send-hook . \"my_hdr From: Other Name <[email protected]>\""

jQuery's .data() does a couple things but it doesn't add the data to the DOM as an attribute. When using it to grab a data attribute, the first thing it does is create a jQuery data object and sets the object's value to the data attribute. After that, it's essentially decoupled from the data attribute.

Example:

<div data-foo="bar"></div>

If you grabbed the value of the attribute using .data('foo'), it would return "bar" as you would expect. If you then change the attribute using .attr('data-foo', 'blah') and then later use .data('foo') to grab the value, it would return "bar" even though the DOM says data-foo="blah". If you use .data() to set the value, it'll change the value in the jQuery object but not in the DOM.

Basically, .data() is for setting or checking the jQuery object's data value. If you are checking it and it doesn't already have one, it creates the value based on the data attribute that is in the DOM. .attr() is for setting or checking the DOM element's attribute value and will not touch the jQuery data value. If you need them both to change you should use both .data() and .attr(). Otherwise, stick with one or the other.

A very dumb issue you can have as well is to define two class Meta in your model. In that case, any change to the first one won't be applied when running makemigrations.

class Product(models.Model):
    somefield = models.CharField(max_length=255)
    someotherfield = models.CharField(max_length=255)

    class Meta:
        indexes = [models.Index(fields=["somefield"], name="somefield_idx")]

    def somefunc(self):
        pass

    # Many lines...

    class Meta:
        indexes = [models.Index(fields=["someotherfield"], name="someotherfield_idx")]

Here is how to kill one or more process from a .bat file.

Step 1. Open a preferred text editor and create a new file.

step 2. To kill one process use the 'taskkill' command, with the '/im' parameter that specifies the image name of the process to be terminated. Example:

taskkill /im examplename.exe

To 'force' kill a process use the '/f' parameter which specifies that processes be forcefully terminated. Example:

taskkill /f /im somecorporateprocess.exe

To kill more than one process you rinse and repeat the first part of step 2. Example:

taskkill /im examplename.exe
taskkill /im examplename1.exe
taskkill /im examplename2.exe

or

taskkill /f /im examplename.exe
taskkill /f /im examplename1.exe
taskkill /f /im examplename2.exe

step 3. Save your file to desired location with the .bat extension.

step 4. click newly created bat file to run it.

I have done the following on a Citrix XenDesktop VM, however you could just do this on your local PC:

Microsoft Virtual PC

If you are running Windows 7, you can download Microsoft virtual PC and create as many copies of Virtual PC as you need for testing without any licensing issues:

• http://www.microsoft.com/windows/virtual-pc/default.aspx

This requires no additional Windows licenses; you simply set up multiple machines with different browsers on them. You can run the browsers out of the window by following the tutorial available here:

• http://ieblog.members.winisp.net/images/InstallingXPMode.htm

Installing Browsers

You will need to create at least 3 virtual PC's (tip: keep the memory down to 256mb for each virtual PC to avoid wasting memory on the virtual desktops).

On the first VPC I installed this:

• http://tredosoft.com/Multiple_IE

along with Chrome 1, Safari 3.1, Opera 8.

On the second I installed Internet Explorer 7, Chrome 3, Safari 3.2.1, Opera 9.

On the third I installed Internet Explorer 8, Chrome 8. Safari 4.0.5, Opera 10.

On Windows 7 (native machine) I had Internet Explorer 9, Chrome 11, Safari 5, Opera 11 and for Firefox I install the following app natively too:

• http://utilu.com/UtiluMFC/

Personally I would not go back further than 5 years with compatibility (other than IE for government networks) unless you have a specific requirement (I split Chrome & Opera across years as I decided there were just to many releases). However, if you find that someone has a specific issue with a site using a specific version of the browser it becomes very easy to install additional virtual machines to run additional browser versions.

Obtaining Older Browsers

You can download older versions of Chrome from here:

• http://www.oldapps.com/google_chrome.php

and Opera here:

• http://www.oldapps.com/opera.php

Virtualizing The Test Platform (Optional)

I use Xen Desktop to virtualize the testing platform so that I can use it anywhere and have included my favorite development tools on there as well:

• http://deliver.citrix.com/go/citrix/XenDesktop

The express edition is available for free.

A Good Commercial Alternative

Another great product I recently came accross is Stylizer which is a CSS editor that installs multiple versions of browsers for testing purposes, however this is a commercial paid for product but is very good and worth the small fee they require to run it.

Use \nolinebreak

\nolinebreak[number]

The \nolinebreak command prevents LaTeX from breaking the current line at the point of the command. With the optional argument, number, you can convert the \nolinebreak command from a demand to a request. The number must be a number from 0 to 4. The higher the number, the more insistent the request is.

Source: http://www.personal.ceu.hu/tex/breaking.htm#nolinebreak

Another solution is the following:

ISNULL(NULLIF(DATEPART(dw,DateField)-1,0),7)

CURL client supports FTP protocol and works for passive mode. Get Download WITHOUT SSL version and you don't need any openssl.dll libraries. Just one curl.exe command line application.
http://www.paehl.com/open_source/?CURL_7.35.0

curl.exe -T c:\test\myfile.dat ftp://ftp.server.com/some/folder/myfile.dat --user myuser:mypwd

Another one is Putty psftp.exe but server key verification prompt requires a trick. This command line inputs NO for prompt meaning key is not stored in registry just this time being used. You need an external script file but sometimes its good if you copy multiple files up and down.
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

echo n | psftp.exe ftp.server.com -l myuser -pw mypwd -b script.txt

script.txt (any ftp command may be typed)

put "C:\test\myfile.dat" "/some/folder/myfile.dat"
quit

Try adding this line to the xml parent layout

 android:animateLayoutChanges="true"

Your layout will look like this

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:animateLayoutChanges="true"
    android:longClickable="false"
    android:orientation="vertical"
    android:weightSum="16">

    .......other code here

    </LinearLayout>

FWIW I created a JavaScript class that can be used at run-time.
It's over on GitHub, here.

There is a readme there with a more in-depth explanation, but I'll do a quick example below:

var ba = new BootstrapAlert();
ba.addP("Some content here");
$("body").append(ba.render());

The above would create a simple primary alert with a paragraph element inside containing the text "Some content here".

There are also options that can be set on initialisation.
For your requirement you'd do:

var ba = new BootstrapAlert({
    dismissible: true,
    background: 'warning'
});
ba.addP("Invalid Credentials");
$("body").append(ba.render());

The render method will return an HTML element, which can then be inserted into the DOM. In this case, we append it to the bottom of the body tag.

This is a work in progress library, but it still is in a very good working order.

Like the firstOrCreate method, updateOrCreate persists the model, so there's no need to call save()

// If there's a flight from Oakland to San Diego, set the price to $99.
// If no matching model exists, create one.

$flight = App\Flight::updateOrCreate(
   ['departure' => 'Oakland', 'destination' => 'San Diego'],
   ['price' => 99]
);

And for your issue

$shopOwner = ShopMeta::updateOrCreate(
   ['shopId' => $theID, 'metadataKey' => '2001'],
   ['other field' => 'val' ,'other field' => 'val', ....]
);

If you don't have an image with that name locally, docker will try to pull it from docker hub, but there's no such image on docker hub. Or simply try "docker login".

OCR which stands for Optical Character Recognition is a computer vision technique used to identify the different types of handwritten digits that are used in common mathematics. To perform OCR in OpenCV we will use the KNN algorithm which detects the nearest k neighbors of a particular data point and then classifies that data point based on the class type detected for n neighbors.

Data Used

This data contains 5000 handwritten digits where there are 500 digits for every type of digit. Each digit is of 20×20 pixel dimensions. We will split the data such that 250 digits are for training and 250 digits are for testing for every class.

Below is the implementation.

Output

91.64

Well, I decided to workout myself on my question to solve the above problem. What I wanted is to implement a simple OCR using KNearest or SVM features in OpenCV. And below is what I did and how. (it is just for learning how to use KNearest for simple OCR purposes).

1) My first question was about letter_recognition.data file that comes with OpenCV samples. I wanted to know what is inside that file.

It contains a letter, along with 16 features of that letter.

And this SOF helped me to find it. These 16 features are explained in the paper Letter Recognition Using Holland-Style Adaptive Classifiers. (Although I didn't understand some of the features at the end)

2) Since I knew, without understanding all those features, it is difficult to do that method. I tried some other papers, but all were a little difficult for a beginner.

So I just decided to take all the pixel values as my features. (I was not worried about accuracy or performance, I just wanted it to work, at least with the least accuracy)

I took the below image for my training data:

(I know the amount of training data is less. But, since all letters are of the same font and size, I decided to try on this).

To prepare the data for training, I made a small code in OpenCV. It does the following things:

1. It loads the image.
2. Selects the digits (obviously by contour finding and applying constraints on area and height of letters to avoid false detections).
3. Draws the bounding rectangle around one letter and wait for key press manually. This time we press the digit key ourselves corresponding to the letter in the box.
4. Once the corresponding digit key is pressed, it resizes this box to 10x10 and saves all 100 pixel values in an array (here, samples) and corresponding manually entered digit in another array(here, responses).
5. Then save both the arrays in separate .txt files.

At the end of the manual classification of digits, all the digits in the training data (train.png) are labeled manually by ourselves, image will look like below:

Below is the code I used for the above purpose (of course, not so clean):

import sys

import numpy as np
import cv2

im = cv2.imread('pitrain.png')
im3 = im.copy()

gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray,(5,5),0)
thresh = cv2.adaptiveThreshold(blur,255,1,1,11,2)

#################      Now finding Contours         ###################

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

samples =  np.empty((0,100))
responses = []
keys = [i for i in range(48,58)]

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,0,255),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            cv2.imshow('norm',im)
            key = cv2.waitKey(0)

            if key == 27:  # (escape to quit)
                sys.exit()
            elif key in keys:
                responses.append(int(chr(key)))
                sample = roismall.reshape((1,100))
                samples = np.append(samples,sample,0)

responses = np.array(responses,np.float32)
responses = responses.reshape((responses.size,1))
print "training complete"

np.savetxt('generalsamples.data',samples)
np.savetxt('generalresponses.data',responses)

Now we enter in to training and testing part.

For the testing part, I used the below image, which has the same type of letters I used for the training phase.

For training we do as follows:

1. Load the .txt files we already saved earlier
2. create an instance of the classifier we are using (it is KNearest in this case)
3. Then we use KNearest.train function to train the data

For testing purposes, we do as follows:

1. We load the image used for testing
2. process the image as earlier and extract each digit using contour methods
3. Draw a bounding box for it, then resize it to 10x10, and store its pixel values in an array as done earlier.
4. Then we use KNearest.find_nearest() function to find the nearest item to the one we gave. ( If lucky, it recognizes the correct digit.)

I included last two steps (training and testing) in single code below:

import cv2
import numpy as np

#######   training part    ############### 
samples = np.loadtxt('generalsamples.data',np.float32)
responses = np.loadtxt('generalresponses.data',np.float32)
responses = responses.reshape((responses.size,1))

model = cv2.KNearest()
model.train(samples,responses)

############################# testing part  #########################

im = cv2.imread('pi.png')
out = np.zeros(im.shape,np.uint8)
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
thresh = cv2.adaptiveThreshold(gray,255,1,1,11,2)

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            roismall = roismall.reshape((1,100))
            roismall = np.float32(roismall)
            retval, results, neigh_resp, dists = model.find_nearest(roismall, k = 1)
            string = str(int((results[0][0])))
            cv2.putText(out,string,(x,y+h),0,1,(0,255,0))

cv2.imshow('im',im)
cv2.imshow('out',out)
cv2.waitKey(0)

And it worked, below is the result I got:

Here it worked with 100% accuracy. I assume this is because all the digits are of the same kind and the same size.

But anyway, this is a good start to go for beginners (I hope so).

As others have hinted, you should consider dumping org.json's library. It's pretty much obsolete these days, and trying to work around its problems is waste of time.

But to specific question; type variable T just does not have any information to help you, as it is little more than compile-time information. Instead you need to pass actual class (as 'Class cls' argument), and you can then create an instance with 'cls.newInstance()'.

For Asp.Net core you better use

<partial name="_MyPartialView" model="MyModel" />

So for example

@foreach (var item in Model)
{
   <partial name="_MyItemView" model="item" />
}

In WSDL definition, bindings contain operations, here comes style for each operation.

Document : In WSDL file, it specifies types details either having inline Or imports XSD document, which describes the structure(i.e. schema) of the complex data types being exchanged by those service methods which makes loosely coupled. Document style is default.

• Advantage:
  • Using this Document style, we can validate SOAP messages against predefined schema. It supports xml datatypes and patterns.
  • loosely coupled.
• Disadvantage: It is a little bit hard to get understand.

In WSDL types element looks as follows:

<types>
 <xsd:schema>
  <xsd:import schemaLocation="http://localhost:9999/ws/hello?xsd=1" namespace="http://ws.peter.com/"/>
 </xsd:schema>
</types>

The schema is importing from external reference.

RPC :In WSDL file, it does not creates types schema, within message elements it defines name and type attributes which makes tightly coupled.

<types/>  
<message name="getHelloWorldAsString">  
<part name="arg0" type="xsd:string"/>  
</message>  
<message name="getHelloWorldAsStringResponse">  
<part name="return" type="xsd:string"/>  
</message>  

• Advantage: Easy to understand.
• Disadvantage:
  • we can not validate SOAP messages.
  • tightly coupled

RPC : No types in WSDL
Document: Types section would be available in WSDL

You can do the following:

TimeSpan duration = b - a;

There's plenty of built in methods in the timespan class to do what you need, i.e.

duration.TotalSeconds
duration.TotalMinutes

I used to dislike std::for_each and thought that without lambda, it was done utterly wrong. However I did change my mind some time ago, and now I actually love it. And I think it even improves readability, and makes it easier to test your code in a TDD way.

The std::for_each algorithm can be read as do something with all elements in range, which can improve readability. Say the action that you want to perform is 20 lines long, and the function where the action is performed is also about 20 lines long. That would make a function 40 lines long with a conventional for loop, and only about 20 with std::for_each, thus likely easier to comprehend.

Functors for std::for_each are more likely to be more generic, and thus reusable, e.g:

struct DeleteElement
{
    template <typename T>
    void operator()(const T *ptr)
    {
        delete ptr;
    }
};

And in the code you'd only have a one-liner like std::for_each(v.begin(), v.end(), DeleteElement()) which is slightly better IMO than an explicit loop.

All of those functors are normally easier to get under unit tests than an explicit for loop in the middle of a long function, and that alone is already a big win for me.

std::for_each is also generally more reliable, as you're less likely to make a mistake with range.

And lastly, compiler might produce slightly better code for std::for_each than for certain types of hand-crafted for loop, as it (for_each) always looks the same for compiler, and compiler writers can put all of their knowledge, to make it as good as they can.

Same applies to other std algorithms like find_if, transform etc.

Use Vim:

diff /path/to/a /path/to/b | vim -R -

Or better still, VimDiff (or vim -d, which is shorter to type) will show differences between two, three or four files side-by-side.

Examples:

vim -d /path/to/[ab]

vimdiff file1 file2 file3 file4

If your objects only contain fields (no methods), this works:

$obj_merged = (object) array_merge((array) $obj1, (array) $obj2);

This actually also works when objects have methods. (tested with PHP 5.3 and 5.6)

Just change the color of layer of the header view

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
  UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0,    tableView.bounds.size.width, 30)] autorelease];
 headerView.layer.backgroundColor = [UIColor clearColor].CGColor
}

Code coverage tools, such as Emma, Cobertura, and Clover, will instrument your code and record which parts of it gets invoked by running a suite of tests. This is very useful, and should be an integral part of your development process. It will help you identify how well your test suite covers your code.

However, this is not the same as identifying real dead code. It only identifies code that is covered (or not covered) by tests. This can give you false positives (if your tests do not cover all scenarios) as well as false negatives (if your tests access code that is actually never used in a real world scenario).

I imagine the best way to really identify dead code would be to instrument your code with a coverage tool in a live running environment and to analyse code coverage over an extended period of time.

If you are runnning in a load balanced redundant environment (and if not, why not?) then I suppose it would make sense to only instrument one instance of your application and to configure your load balancer such that a random, but small, portion of your users run on your instrumented instance. If you do this over an extended period of time (to make sure that you have covered all real world usage scenarios - such seasonal variations), you should be able to see exactly which areas of your code are accessed under real world usage and which parts are really never accessed and hence dead code.

I have never personally seen this done, and do not know how the aforementioned tools can be used to instrument and analyse code that is not being invoked through a test suite - but I am sure they can be.

if you want to only search with attribute name with any value

from bs4 import BeautifulSoup
import re

soup= BeautifulSoup(html.text,'lxml')
results = soup.findAll("td", {"valign" : re.compile(r".*")})

as per Steve Lorimer better to pass True instead of regex

results = soup.findAll("td", {"valign" : True})

In java 8 , It's really easy to get timestamp in UTC by using java 8 java.time.Instant library :

Instant.now();

That few word of code will return the UTC Timestamp.

UPDATE:

To append Token to each request you can create one Interceptor as below.

import { Injectable } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const token = window.localStorage.getItem('tokenKey'); // you probably want to store it in localStorage or something


    if (!token) {
      return next.handle(req);
    }

    const req1 = req.clone({
      headers: req.headers.set('Authorization', `${token}`),
    });

    return next.handle(req1);
  }

}

• How to get total RAM size of a device?

This getMemorySize() method is returned MemorySize that has total and free memory size.
I don't believe this code perfectly.
This code is testing on LG G3 cat.6 (v5.0.1)

    private MemorySize getMemorySize() {
        final Pattern PATTERN = Pattern.compile("([a-zA-Z]+):\\s*(\\d+)");

        MemorySize result = new MemorySize();
        String line;
        try {
            RandomAccessFile reader = new RandomAccessFile("/proc/meminfo", "r");
            while ((line = reader.readLine()) != null) {
                Matcher m = PATTERN.matcher(line);
                if (m.find()) {
                    String name = m.group(1);
                    String size = m.group(2);

                    if (name.equalsIgnoreCase("MemTotal")) {
                        result.total = Long.parseLong(size);
                    } else if (name.equalsIgnoreCase("MemFree") || name.equalsIgnoreCase("Buffers") ||
                            name.equalsIgnoreCase("Cached") || name.equalsIgnoreCase("SwapFree")) {
                        result.free += Long.parseLong(size);
                    }
                }
            }
            reader.close();

            result.total *= 1024;
            result.free *= 1024;
        } catch (IOException e) {
            e.printStackTrace();
        }

        return result;
    }

    private static class MemorySize {
        public long total = 0;
        public long free = 0;
    }

I know that Pattern.compile() is expensive cost so You may move its code to class member.

I have installed my wamp server in D: drive so u have to go to the following path from ur command line->(and if u have installed ur wamp in c: drive then just replace the d: wtih c: here)

D:\>cd wamp
D:\wamp>cd bin
D:\wamp\bin>cd mysql
D:\wamp\bin\mysql>cd mysql5.5.8 (whatever ur verserion will be displayed here use keyboard Tab button and select the currently working mysql version on your server if you have more than one mysql versions)
D:\wamp\bin\mysql\mysql5.5.8>cd bin
D:\wamp\bin\mysql\mysql5.5.8\bin>mysqldump -u root -p password db_name > "d:\backupfile.sql"

here root is user of my phpmyadmin password is the password for phpmyadmin so if u haven't set any password for root just nothing type at that place, db_name is the database (for which database u r taking the backup) ,backupfile.sql is the file in which u want ur backup of ur database and u can also change the backup file location(d:\backupfile.sql) from to any other place on your computer

I know it's an old question, but I needed this solution too, and I acme with another solution.

I used an entrypoint.sh to execute the following line, and define a variable with the actual hostname for that instance:

HOST=`hostname --fqdn`

Then, I used it across my entrypoint script:

echo "Value: $HOST"

Hope this helps

Download the developer edition. There you can choose Express as license when installing.

#!/usr/bin/python3 is a shebang line.

A shebang line defines where the interpreter is located. In this case, the python3 interpreter is located in /usr/bin/python3. A shebang line could also be a bash, ruby, perl or any other scripting languages' interpreter, for example: #!/bin/bash.

Without the shebang line, the operating system does not know it's a python script, even if you set the execution flag (chmod +x script.py) on the script and run it like ./script.py. To make the script run by default in python3, either invoke it as python3 script.py or set the shebang line.

You can use #!/usr/bin/env python3 for portability across different systems in case they have the language interpreter installed in different locations.

public class LambdaScopeTest {
    public int x = 0;        
    class FirstLevel {
        public int x = 1;    
        void methodInFirstLevel(int x) {

            // The following statement causes the compiler to generate
            // the error "local variables referenced from a lambda expression
            // must be final or effectively final" in statement A:
            //
            // x = 99; 

        }
    }    
}

As others have said, a variable or parameter whose value is never changed after it is initialized is effectively final. In the above code, if you change the value of x in inner class FirstLevel then the compiler will give you the error message:

Local variables referenced from a lambda expression must be final or effectively final.

    File file = fileChooser.getSelectedFile();

You can follow one of the below approaches:

1) Basic, single type :

//One type
public static <T> void fill(List <T> list, T val) {

    for(int i=0; i<list.size(); i++){
        list.set(i, val);
    }

}

2) Multiple Types :

// multiple types as parameters
public static <T1, T2> String multipleTypeArgument(T1 val1, T2 val2) {

    return val1+" "+val2;

}

3) Below will raise compiler error as 'T3 is not in the listing of generic types that are used in function declaration part.

//Raised compilation error
public static <T1, T2> T3 returnTypeGeneric(T1 val1, T2 val2) {
    return 0;
}

Correct : Compiles fine

public static <T1, T2, T3> T3 returnTypeGeneric(T1 val1, T2 val2) {
    return 0;
}

Sample Class Code :

package generics.basics;

import java.util.ArrayList;
import java.util.List;

public class GenericMethods {

/*
 Declare the generic type parameter T in this method. 

 After the qualifiers public and static, you put <T> and 
 then followed it by return type, method name, and its parameters.

 Observe : type of val is 'T' and not '<T>'

 * */
//One type
public static <T> void fill(List <T> list, T val) {

    for(int i=0; i<list.size(); i++){
        list.set(i, val);
    }

}

// multiple types as parameters
public static <T1, T2> String multipleTypeArgument(T1 val1, T2 val2) {

    return val1+" "+val2;

}

/*// Q: To audience -> will this compile ? 
 * 
 * public static <T1, T2> T3 returnTypeGeneric(T1 val1, T2 val2) {

    return 0;

}*/

 public static <T1, T2, T3> T3 returnTypeGeneric(T1 val1, T2 val2) {

    return null;

}

public static void main(String[] args) {
    List<Integer> list = new ArrayList<>();
    list.add(10);
    list.add(20);
    System.out.println(list.toString());
    fill(list, 100);
    System.out.println(list.toString());

    List<String> Strlist = new ArrayList<>();
    Strlist.add("Chirag");
    Strlist.add("Nayak");
    System.out.println(Strlist.toString());
    fill(Strlist, "GOOD BOY");
    System.out.println(Strlist.toString());


    System.out.println(multipleTypeArgument("Chirag", 100));
    System.out.println(multipleTypeArgument(100,"Nayak"));

}

}

// class definition ends

Sample Output:

[10, 20]
[100, 100]
[Chirag, Nayak]
[GOOD BOY, GOOD BOY]
Chirag 100
100 Nayak

Or you can just initialize inline in the controller. If you use an init function internal to the controller, it doesn't need to be defined in the scope. In fact, it can be self executing:

function MyCtrl($scope) {
    $scope.isSaving = false;

    (function() {  // init
        if (true) { // $routeParams.Id) {
            //get an existing object
        } else {
            //create a new object
        }
    })()

    $scope.isClean = function () {
       return $scope.hasChanges() && !$scope.isSaving;
    }

    $scope.hasChanges = function() { return false }
}

Using Erik's answer, as a starting point. I found a simpler solution that worked for me.

In my ng-click function I have:

var the_string = 'lifeMeaning';
if ($scope[the_string] === undefined) {
   //Valid in my application for first usage
   $scope[the_string] = true;
} else {
   $scope[the_string] = !$scope[the_string];
}
//$scope.$apply

I've tested it with and without $scope.$apply. Works correctly without it!

Copy-paste snippet:

import importlib
def str_to_class(module_name, class_name):
    """Return a class instance from a string reference"""
    try:
        module_ = importlib.import_module(module_name)
        try:
            class_ = getattr(module_, class_name)()
        except AttributeError:
            logging.error('Class does not exist')
    except ImportError:
        logging.error('Module does not exist')
    return class_ or None

My understanding from Apple Docs.

• What is Architectures (ARCHS) into Xcode build-settings?
  • Specifies architecture/s to which the binary is TARGETED. When specified more that one architecture, the generated binary may contain object code for each of the specified architecture.

• What is Valid Architectures (VALID_ARCHS) into Xcode build-settings?

  • Specifies architecture/s for which the binary may be BUILT.
  • During build process, this list is intersected with ARCHS and the resulting list specifies the architectures the binary can run on.

• Example :- One iOS project has following build-settings into Xcode.

  • ARCHS = armv7 armv7s
  • VALID_ARCHS = armv7 armv7s arm64
  • In this case, binary will be built for armv7 armv7s arm64 architectures. But the same binary will run on ONLY ARCHS = armv7 armv7s.

If you just want to display it when you get a response add this to your loadpage()

function loadpage(page_request, containerid){
   if (page_request.readyState == 4 && page_request.status==200) { 
      var container = document.getElementById(containerid);
      container.innerHTML=page_request.responseText;
      container.style.visibility = 'visible';
      // or 
      container.style.display = 'block';
}

but this depend entirely on how you hid the div in the first place

VERY EASY:

just use this to replace all white spaces with -:

myString.replace(/ /g,"-")

Because Dictionary is a generic class ( Dictionary<TKey, TValue> ), so that accessing its content is type-safe (i.e. you do not need to cast from Object, as you do with a Hashtable).

Compare

var customers = new Dictionary<string, Customer>();
...
Customer customer = customers["Ali G"];

to

var customers = new Hashtable();
...
Customer customer = customers["Ali G"] as Customer;

However, Dictionary is implemented as hash table internally, so technically it works the same way.

Just another solution using underscore.js:

_.extend({}, obj1, obj2);

With nginx you can send both tokens like this (even though it's against the standard):

Authorization: Basic basic-token,Bearer bearer-token

This works as long as the basic token is first - nginx successfully forwards it to the application server.

And then you need to make sure your application can properly extract the Bearer from the above string.

Use jQuery multiple-selector if the only difference between the two functions is the value of the button being triggered.

$("#button_1, #button_2").on("click", function(e) {
    e.preventDefault();
    $.ajax({type: "POST",
        url: "/pages/test/",
        data: { id: $(this).val(), access_token: $("#access_token").val() },
        success:function(result) {
          alert('ok');
        },
        error:function(result) {
          alert('error');
        }
    });
});

Then You can refer Date Library to get the custom calculation date and time functions in node.

To use it client side refer this link, download index.js and assertHelper.js and include that in your HTML.

<script src="assertHelper.js"></script>
<script type="text/javascript" src="index.js"></script>
$( document ).ready(function() {
    DateLibrary.getDayOfWeek(new Date("2015-06-15"),{operationType:"Day_of_Week"}); // Output : Monday
}

You can use different functions as given in examples to get custom dates.

If first day of week is Sunday, what day will be on 15th June 2015.

 DateLibrary.getDayOfWeek(new Date("2015-06-15"),
    {operationType:"Day_Number_of_Week",
        startDayOfWeek:"Sunday"}) // Output : 1

If first day of week is Tuesday, what week number in year will be follow in 15th June 2015 as one of the date.

 DateLibrary.getWeekNumber(new Date("2015-06-15"),
    {operationType:"Week_of_Year",
        startDayOfWeek:"Tuesday"}) // Output : 24

Refer other functions to fulfill your custom date requirements.

It may be time consuming to get all the application Ids from YARN and kill them one by one. You can use a Bash for loop to accomplish this repetitive task quickly and more efficiently as shown below:

Kill all applications on YARN which are in ACCEPTED state:

for x in $(yarn application -list -appStates ACCEPTED | awk 'NR > 2 { print $1 }'); do yarn application -kill $x; done

Kill all applications on YARN which are in RUNNING state:

for x in $(yarn application -list -appStates RUNNING | awk 'NR > 2 { print $1 }'); do yarn application -kill $x; done

# Over-explaining a bit:
def magic(numList):         # [1,2,3]
    s = map(str, numList)   # ['1','2','3']
    s = ''.join(s)          # '123'
    s = int(s)              # 123
    return s


# How I'd probably write it:
def magic(numList):
    s = ''.join(map(str, numList))
    return int(s)


# As a one-liner  
num = int(''.join(map(str,numList)))


# Functionally:
s = reduce(lambda x,y: x+str(y), numList, '')
num = int(s)


# Using some oft-forgotten built-ins:
s = filter(str.isdigit, repr(numList))
num = int(s)

Example (Demo):

<a href="mailto:[email protected]?subject=Suggestions&body=name:%0D%0Aemail:">test</a>?
                                                                  ^^^^^^

Powerlord answer is indeed the best and I would recommend one more change: use LIMIT to make sure db would not get overloaded:

SELECT firstname, lastname, list.address FROM list
INNER JOIN (SELECT address FROM list
GROUP BY address HAVING count(id) > 1) dup ON list.address = dup.address
LIMIT 10

It is a good habit to use LIMIT if there is no WHERE and when making joins. Start with small value, check how heavy the query is and then increase the limit.

You can simply do

node --version

or short form would also do

node -v

If above commands does not work, you have done something wrong in installation, reinstall the node.js and try.

yield is just like return - it returns whatever you tell it to (as a generator). The difference is that the next time you call the generator, execution starts from the last call to the yield statement. Unlike return, the stack frame is not cleaned up when a yield occurs, however control is transferred back to the caller, so its state will resume the next time the function is called.

In the case of your code, the function get_child_candidates is acting like an iterator so that when you extend your list, it adds one element at a time to the new list.

list.extend calls an iterator until it's exhausted. In the case of the code sample you posted, it would be much clearer to just return a tuple and append that to the list.

All of these answers are wrong!

Like I said in my comment, the reason you're getting that error because the URL fails the "Same origin policy", but you can still us the AJAX function to hit another domain, see Nick Cravers answer on this similar question:

You need to trigger JSONP behavior with $.getJSON() by adding &callback=? on the querystring, like this:

$.getJSON("http://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=content&titles="+title+"&format=json&callback=?",
function(data) {
    doSomethingWith(data); 
}); 

You can test it here.

Without using JSONP you're hitting the same-origin policy which is blocking the XmlHttpRequest from getting any data back.

With this in mind, the follow code should work:

var fbURL="https://graph.facebook.com/16453004404_481759124404/comments?access_token=my_token";

$.ajax({
    url: fbURL+"&callback=?",
    data: "message="+commentdata,
    type: 'POST',
    success: function (resp) {

If you build apk via command line like me then you can provide signing configuration as arguments.

Add this to your build.gradle

def getStore = { ->
    def result = project.hasProperty('storeFile') ? storeFile : "null"
    return result
}

def getStorePassword = { ->
    def result = project.hasProperty('storePassword') ? storePassword : ""
    return result
}

def getKeyAlias = { ->
    def result = project.hasProperty('keyAlias') ? keyAlias : ""
    return result
}

def getKeyPassword = { ->
    def result = project.hasProperty('keyPassword') ? keyPassword : ""
    return result
}

Make your signingConfigs like this

signingConfigs {
    release {
        storeFile file(getStore())
        storePassword getStorePassword()
        keyAlias getKeyAlias()
        keyPassword getKeyPassword()
    }
}

Then you execute gradlew like this

./gradlew assembleRelease -PstoreFile="keystore.jks" -PstorePassword="password" -PkeyAlias="alias" -PkeyPassword="password"

this worked for me. to pass an array of Item object {ItemID,ColorID,SizeID,Quntity}

For me work ONLY this variant:

RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Another option is the openxlsx-package. It doesn't depend on java and can read, edit and write Excel-files. From the description from the package:

openxlsx simplifies the the process of writing and styling Excel xlsx files from R and removes the dependency on Java

Example usage:

library(openxlsx)

# read data from an Excel file or Workbook object into a data.frame
df <- read.xlsx('name-of-your-excel-file.xlsx')

# for writing a data.frame or list of data.frames to an xlsx file
write.xlsx(df, 'name-of-your-excel-file.xlsx')

Besides these two basic functions, the openxlsx-package has a host of other functions for manipulating Excel-files.

For example, with the writeDataTable-function you can create formatted tables in an Excel-file.

The focus only works if the window is focused.

Use ((JavascriptExecutor)webDriver).executeScript("window.focus();"); to be sure.

I'd recommend this article on CSS Tricks by Chris Coyier entitled Better Helvetica:

http://css-tricks.com/snippets/css/better-helvetica/

He basically recommends the following declaration for covering all the bases:

body {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: 300;
}

also you can reimplement protected member QWidget::closeEvent()

void YourWidgetWithXButton::closeEvent(QCloseEvent *event)
{
    // do what you need here
    // then call parent's procedure
    QWidget::closeEvent(event);
}

store a start time and increment your framecounter once per loop? every few seconds you could just print framecount/(Now - starttime) and then reinitialize them.

edit: oops. double-ninja'ed

You must set up proper encoding and collation for your tables.

Table encoding must reflect the actual data encoding. What is your data encoding?

To see table encoding, you can run a query SHOW CREATE TABLE tablename

How about this one-liner?

var isAndroid = /(android)/i.test(navigator.userAgent);

The i modifier is used to perform case-insensitive matching.

This answer is inspired by post Angular 2: Focus on newly added input element

Steps to set the focus on Html element in Angular2

1. Import ViewChildren in your Component

   import { Input, Output, AfterContentInit, ContentChild,AfterViewInit, ViewChild, ViewChildren } from 'angular2/core';
   

2. Declare local template variable name for the html for which you want to set the focus

3. Implement the function ngAfterViewInit() or other appropriate life cycle hooks

4. Following is the piece of code which I used for setting the focus

   ngAfterViewInit() {vc.first.nativeElement.focus()}
   

5. Add #input attribute to the DOM element you want to access.

///This is typescript_x000D_

%g in string formatting will format a float rounded to some number of significant figures. It will sometimes use 'e' scientific notation, so convert the rounded string back to a float then through %s string formatting.

>>> '%s' % float('%.1g' % 1234)
'1000'
>>> '%s' % float('%.1g' % 0.12)
'0.1'
>>> '%s' % float('%.1g' % 0.012)
'0.01'
>>> '%s' % float('%.1g' % 0.062)
'0.06'
>>> '%s' % float('%.1g' % 6253)
'6000.0'
>>> '%s' % float('%.1g' % 1999)
'2000.0'

You can use !!, but if you want to do it recursively then below is one way to do it:

dataAt :: Int -> [a] -> a
dataAt _ [] = error "Empty List!"
dataAt y (x:xs)  | y <= 0 = x
                 | otherwise = dataAt (y-1) xs

Alex provided the correct reason for not being able to do what you're trying to do, so +1. But you are encountering this issue because you're not quite using resolves how they're designed.

resolve takes either the string of a service or a function returning a value to be injected. Since you're doing the latter, you need to pass in an actual function:

resolve: {
  data: function (dbService) {
    return dbService.getData();
  }
}

When the framework goes to resolve data, it will inject the dbService into the function so you can freely use it. You don't need to inject into the config block at all to accomplish this.

Bon appetit!

Users codelogic and harley are correct, but keep in mind if you know the string is an integer (for example, 545) you can call int("545") without first casting to float.

If your strings are in a list, you could use the map function as well.

>>> x = ["545.0", "545.6", "999.2"]
>>> map(float, x)
[545.0, 545.60000000000002, 999.20000000000005]
>>>

It is only good if they're all the same type.

This is a common question. In base, the option you're looking for is aggregate. Assuming your data.frame is called "mydf", you can use the following.

> aggregate(B ~ A, mydf, sum)
  A  B
1 1  5
2 2  3
3 3 11

I would also recommend looking into the "data.table" package.

> library(data.table)
> DT <- data.table(mydf)
> DT[, sum(B), by = A]
   A V1
1: 1  5
2: 2  3
3: 3 11

StringUtils is part of Apache Commons Lang (http://commons.apache.org/lang/, and as the name suggest it provides some nice utilities for dealing with Strings, going beyond what is offered in java.lang.String. It consists of over 50 static methods.

There are two different versions available, the newer org.apache.commons.lang3.StringUtils and the older org.apache.commons.lang.StringUtils. There are not really any significant differences between the two. lang3.StringUtils requires Java 5.0 and is probably the version you'll want to use.

same as a normal modulo 3.14 % 6.28 = 3.14, just like 3.14%4 =3.14 3.14%2 = 1.14 (the remainder...)

Why do you use new Array(); for hash? You need to use new Object() instead.

And i think you will get what you want.

XML-RPC is part of the Python standard library:

I wanted to specify two points which kept causing me problems.

• I was creating the Gesture Recognizer on init and storing it in a let property. Apparently, adding this gesture recog to the view does not work. May be self object passed to the gesture recognizer during init, is not properly configured.
• The gesture recognizer should not be added to views with zero frames. I create all my views with zero frame and then resize them using autolayout. The gesture recognizers have to be added AFTER the views have been resized by the autolayout engine. So I add the gesture recognizer in viewDidAppear and they work.

It depends on what exactly you want to accomplish. Let's assume you have this structure:

<p style="width:400px;">
    Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt. Cras dapibus. Vivamus elementum semper nisi. Aenean vulputate eleifend tellus. Aenean leo ligula, porttitor eu, consequat vitae, eleifend ac, enim. Aliquam lorem ante, dapibus in, viverra quis, feugiat a, tellus. Phasellus viverra nulla ut metus varius laoreet.
</p>

If you want the space between the single lines to be bigger, you should increase

line-height

If you want the space at the end to be bigger, you should increase

margin-bottom

If you want the space at the end to be bigger, but have the background fill the space (or the border around the space) use

padding-bottom

Of course, there are also the corresponding values for space on the top:

padding-top
margin-top

Some examples:

<p style="line-height: 30px; width: 300px; border: 1px solid black;">
     Space between single lines 
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
</p>
<p style="margin-bottom: 30px; width: 300px; border: 1px solid black;">
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
</p>
<p style="padding-bottom: 30px; width: 300px; border: 1px solid black;">
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border

     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border

Set the PATH variable, like you're doing. If you're running the program from the IDE, you can modify environment variables by adjusting the Debugging options in the project properties.

If the DLLs are named such that you don't need different paths for the different configuration types, you can add the path to the system PATH variable or to Visual Studio's global one in Tools | Options.

I had the same issue just add this function to the open dialog options and it worked sharm

open: function(){
            var closeBtn = $('.ui-dialog-titlebar-close');
            closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
        },

and on close event you need to remove that

close: function () {
            var closeBtn = $('.ui-dialog-titlebar-close');
            closeBtn.html('');}

Complete example

<div id="deleteDialog" title="Confirm Delete">
 Can you confirm you want to delete this event?
</div> 

$("#deleteDialog").dialog({
                width: 400, height: 200,
                modal: true,
                open: function () {
                    var closeBtn = $('.ui-dialog-titlebar-close');
                    closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
                },
                close: function () {
                    var closeBtn = $('.ui-dialog-titlebar-close');
                    closeBtn.html('');
                },
                buttons: {
                    "Confirm": function () {
                        calendar.fullCalendar('removeEvents', event._id);
                        $(this).dialog("close");
                    },
                    "Cancel": function () {
                        $(this).dialog("close");
                    }
                }
            });

            $("#dialog").dialog("open");

Use these:

webview.getSettings().setBuiltInZoomControls(true);
webview.getSettings().setDisplayZoomControls(false);

here's non-paste methods

awk

awk 'BEGIN {OFS=" "}{
  getline line < "file2"
  print $0,line
} ' file1

Bash

exec 6<"file2"
while read -r line
do
    read -r f2line <&6
    echo "${line}${f2line}"
done <"file1"
exec 6<&-

I just experienced this issue and it was because I was trying to run a script from the wrong directory.. doh! It happens to the best of us.

Use the sed delete command with a range address. For example:

sed 1,100d file.txt # Print file.txt omitting lines 1-100.

Alternatively, if you want to only print a known range, use the print command with the -n flag:

sed -n 201,300p file.txt # Print lines 201-300 from file.txt

This solution should work reliably on all Unix systems, regardless of the presence of GNU utilities.

While the accepted answer is technically correct, a more practical approach, if possible, is to just strip whitespace out of both the regular expression and the search string.

If you want to search for "my cats", instead of:

myString.match(/m\s*y\s*c\s*a\*st\s*s\s*/g)

Just do:

myString.replace(/\s*/g,"").match(/mycats/g)

Warning: You can't automate this on the regular expression by just replacing all spaces with empty strings because they may occur in a negation or otherwise make your regular expression invalid.

I have edited one of the previous post. Now, it is way more simple and it works perfectly.

Since posting the answer the latest versions of browsers prevent the command from working. I'll leave the answer visible but note it ONLY works on older browser versions.

Most browsers prevent you from closing windows with javascript that were not opened with window.open("https://example_url.com") however, it is still possible to close the current window using the following command:

window.open('','_self').close()

This loads a blank url (the first argument) in the current window (the second argument) and then instantaneously closes the window. This works because when close() is called, the current window has been opened by javascript.

curl_getinfo() must be added before closing the curl handler

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/bar");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "someusername:secretpassword");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info['request_header']);
curl_close($ch);

In addtion to Sinan Ünür comprehensive listing of string comparison operators, Perl 5.10 adds the smart match operator.

The smart match operator compares two items based on their type. See the chart below for the 5.10 behavior (I believe this behavior is changing slightly in 5.10.1):

perldoc perlsyn "Smart matching in detail":

The behaviour of a smart match depends on what type of thing its arguments are. It is always commutative, i.e. $a ~~ $b behaves the same as $b ~~ $a . The behaviour is determined by the following table: the first row that applies, in either order, determines the match behaviour.

  $a      $b        Type of Match Implied    Matching Code
  ======  =====     =====================    =============
  (overloading trumps everything)

  Code[+] Code[+]   referential equality     $a == $b   
  Any     Code[+]   scalar sub truth         $b->($a)   

  Hash    Hash      hash keys identical      [sort keys %$a]~~[sort keys %$b]

  Any     Num       numeric equality         $a == $b   

  Any     Any       string equality          $a eq $b   

+ - this must be a code reference whose prototype (if present) is not ""
(subs with a "" prototype are dealt with by the 'Code()' entry lower down) 
* - that is, each element matches the element of same index in the other
array. If a circular reference is found, we fall back to referential 
equality.   
! - either a real number, or a string that looks like a number

The "matching code" doesn't represent the real matching code, of course: it's just there to explain the intended meaning. Unlike grep, the smart match operator will short-circuit whenever it can.

Custom matching via overloading You can change the way that an object is matched by overloading the ~~ operator. This trumps the usual smart match semantics. See overload.

Simply use the global keyword.

e.g.:

class myClass() {
    private function foo() {
        global $MyNumber;
        ...

$MyNumber will then become accessible (and indeed modifyable) within that method.

However, the use of globals is often frowned upon (they can give off a bad code smell), so you might want to consider using a singleton class to store anything of this nature. (Then again, without knowing more about what you're trying to achieve this might be a very bad idea - a define could well be more useful.)

You want a check constraint.

CHECK constraints determine the valid values from a logical expression that is not based on data in another column. For example, the range of values for a salary column can be limited by creating a CHECK constraint that allows for only data that ranges from $15,000 through $100,000. This prevents salaries from being entered beyond the regular salary range.

You want something like:

ALTER TABLE dbo.Table ADD CONSTRAINT CK_Table_Frequency
    CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))

You can also implement check constraints with scalar functions, as described in the link above, which is how I prefer to do it.

With Rails 4 it's easy:

 Foo.includes(:bar).where.not(bars: {id: nil})

See also: http://guides.rubyonrails.org/active_record_querying.html#not-conditions

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

This can not be done easily. There's no way to make an NVARCHAR parameter take "more than one value". What I've done before is - as you do already - make the parameter value like a list with comma-separated values. Then, split this string up into its parts in the stored procedure.

Splitting up can be done using string functions. Add every part to a temporary table. Pseudo-code for this could be:

CREATE TABLE #TempTable (ID INT)
WHILE LEN(@PortfolioID) > 0
BEGIN
    IF NOT <@PortfolioID contains Comma>
    BEGIN
        INSERT INTO #TempTable VALUES CAST(@PortfolioID as INT)
        SET @PortfolioID = ''
    END ELSE
    BEGIN
         INSERT INTO #Temptable VALUES CAST(<Part until next comma> AS INT)
         SET @PortfolioID = <Everything after the next comma>
    END
END

Then, change your condition to

WHERE PortfolioId IN (SELECT ID FROM #TempTable)

EDIT
You may be interested in the documentation for multi value parameters in SSRS, which states:

You can define a multivalue parameter for any report parameter that you create. However, if you want to pass multiple parameter values back to a data source by using the query, the following requirements must be satisfied:

The data source must be SQL Server, Oracle, Analysis Services, SAP BI NetWeaver, or Hyperion Essbase.

The data source cannot be a stored procedure. Reporting Services does not support passing a multivalue parameter array to a stored procedure.

The query must use an IN clause to specify the parameter.

This I found here.

Stack memory is specifically the range of memory that is accessible via the Stack register of the CPU. The Stack was used as a way to implement the "Jump-Subroutine"-"Return" code pattern in assembly language, and also as a means to implement hardware-level interrupt handling. For instance, during an interrupt, the Stack was used to store various CPU registers, including Status (which indicates the results of an operation) and Program Counter (where was the CPU in the program when the interrupt occurred).

Stack memory is very much the consequence of usual CPU design. The speed of its allocation/deallocation is fast because it is strictly a last-in/first-out design. It is a simple matter of a move operation and a decrement/increment operation on the Stack register.

Heap memory was simply the memory that was left over after the program was loaded and the Stack memory was allocated. It may (or may not) include global variable space (it's a matter of convention).

Modern pre-emptive multitasking OS's with virtual memory and memory-mapped devices make the actual situation more complicated, but that's Stack vs Heap in a nutshell.

Try this example.

<?php 
 $url = 'http://localhost/test/page2.php';
    $data = array("first_name" => "First name","last_name" => "last name","email"=>"[email protected]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
    $ch=curl_init($url);
    $data_string = urlencode(json_encode($data));
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, array("customer"=>$data_string));


    $result = curl_exec($ch);
    curl_close($ch);

    echo $result;
?>

Your page2.php code

<?php
$datastring = $_POST['customer'];
$data = json_decode( urldecode( $datastring));

?>

The error message the OP is encountering is just an Eclipse feature. If you are willing to tie your code to a specific maker (and even version) of the JVM, you can effectively use method sun.reflect.Reflection.getCallerClass(). You can then compile the code outside of Eclipse or configure it not to consider this diagnostic an error.

The worse Eclipse configuration is to disable all occurrences of the error by:

Project Properties / Java Compiler / Errors/Warnings / Enable project specific settings set to checked / Deprecated and restrited API / Forbidden reference (access rules) set to Warning or Ignore.

The better Eclipse configuration is to disable a specific occurrence of the error by:

Project Properties / Java Build Path / Libraries / JRE System Library expand / Access rules: select / Edit... / Add... / Resolution: set to Discouraged or Accessible / Rule Pattern set to sun/reflect/Reflection.

You can also use gdb instead of addr2line to examine memory address. Load executable file in gdb and print the name of a symbol which is stored at the address. 16 Examining the Symbol Table.

Building on other posted answers.

Both of these will produce the right values:

select distributor_id,
    count(*) total,
    sum(case when level = 'exec' then 1 else 0 end) ExecCount,
    sum(case when level = 'personal' then 1 else 0 end) PersonalCount
from yourtable
group by distributor_id

SELECT a.distributor_id,
          (SELECT COUNT(*) FROM myTable WHERE level='personal' and distributor_id = a.distributor_id) as PersonalCount,
          (SELECT COUNT(*) FROM myTable WHERE level='exec' and distributor_id = a.distributor_id) as ExecCount,
          (SELECT COUNT(*) FROM myTable WHERE distributor_id = a.distributor_id) as TotalCount
       FROM myTable a ; 

However, the performance is quite different, which will obviously be more relevant as the quantity of data grows.

I found that, assuming no indexes were defined on the table, the query using the SUMs would do a single table scan, while the query with the COUNTs would do multiple table scans.

As an example, run the following script:

IF OBJECT_ID (N't1', N'U') IS NOT NULL 
drop table t1

create table t1 (f1 int)


    insert into t1 values (1) 
    insert into t1 values (1) 
    insert into t1 values (2)
    insert into t1 values (2)
    insert into t1 values (2)
    insert into t1 values (3)
    insert into t1 values (3)
    insert into t1 values (3)
    insert into t1 values (3)
    insert into t1 values (4)
    insert into t1 values (4)
    insert into t1 values (4)
    insert into t1 values (4)
    insert into t1 values (4)


SELECT SUM(CASE WHEN f1 = 1 THEN 1 else 0 end),
SUM(CASE WHEN f1 = 2 THEN 1 else 0 end),
SUM(CASE WHEN f1 = 3 THEN 1 else 0 end),
SUM(CASE WHEN f1 = 4 THEN 1 else 0 end)
from t1

SELECT 
(select COUNT(*) from t1 where f1 = 1),
(select COUNT(*) from t1 where f1 = 2),
(select COUNT(*) from t1 where f1 = 3),
(select COUNT(*) from t1 where f1 = 4)

Highlight the 2 SELECT statements and click on the Display Estimated Execution Plan icon. You will see that the first statement will do one table scan and the second will do 4. Obviously one table scan is better than 4.

Adding a clustered index is also interesting. E.g.

Create clustered index t1f1 on t1(f1);
Update Statistics t1;

The first SELECT above will do a single Clustered Index Scan. The second SELECT will do 4 Clustered Index Seeks, but they are still more expensive than a single Clustered Index Scan. I tried the same thing on a table with 8 million rows and the second SELECT was still a lot more expensive.

You can use CAST and CONVERT to switch between different types of encodings. See: http://dev.mysql.com/doc/refman/5.0/en/charset-convert.html

SELECT column1, CONVERT(column2 USING utf8)
FROM my_table 
WHERE my_condition;

[class*="col-"]
  padding: 0
  margin: 0

You haven't got your SUMIF in the correct order - it needs to be range, criteria, sum range. Try:

=SUMIF(A:A,">="&DATE(2012,1,1),B:B)

DispatchQueue.main.async {
    self.renderTargetNode(floorPosition: targetPosition, animated: closedContour) {
        group.leave()
        // first done

I tried this and it worked for me

add these lines to Makefile

clean:
    rm *.o output

new: clean
    $(MAKE)     #use variable $(MAKE) instead of make to get recursive make calls

save and now call

make new 

and it will recompile everything again

What happened?

1) 'new' calls clean. 'clean' do 'rm' which removes all object files that have the extension of '.o'.

2) 'new' calls 'make'. 'make' see that there is no '.o' files, so it creates all the '.o' again. then the linker links all of the .o file int one executable output

Good luck

This phrase is almost certainly an analogy with a phase in house construction — "stubbing out" plumbing. During construction, while the walls are still open, the rough plumbing is put in. This is necessary for the construction to continue. Then, when everything around it is ready enough, one comes back and adds faucets and toilets and the actual end-product stuff. (See for example How to Install a Plumbing Stub-Out.)

When you "stub out" a function in programming, you build enough of it to work around (for testing or for writing other code). Then, you come back later and replace it with the full implementation.

I developed my own SQL Server 2016+ JSON parser a while ago. I use this in all my projects - very good performance. I hope it can help someone else too.

Full code of the function:

Look into xcopy, which will recursively copy files and subdirectories.

There are examples, 2/3 down the page. Of particular use is:

To copy all the files and subdirectories (including any empty subdirectories) from drive A to drive B, type:

xcopy a: b: /s /e

In Java, when you type a decimal number as 3.6, its interpreted as a double. double is a 64-bit precision IEEE 754 floating point, while floatis a 32-bit precision IEEE 754 floating point. As a float is less precise than a double, the conversion cannot be performed implicitly.

If you want to create a float, you should end your number with f (i.e.: 3.6f).

For more explanation, see the primitive data types definition of the Java tutorial.

See ?which.max

> which.max( matrix[,2] )

You can try something like this. Here on click of image button I toggle the imageview.

holder.imgitem.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            if(!onclick){
            mSparseBooleanArray.put((Integer) view.getTag(), true);
            holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_delete_overlay_com);
            onclick=true;}
            else if(onclick)
            {
                 mSparseBooleanArray.put((Integer) view.getTag(), false);
                  holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_selection_com);

            onclick=false;
            }
        }
    });

You have a line break <br> in-between the second and third images in your markup. Get rid of that, and it'll show inline.

You can sort a int array with Arrays.sort( array ).

Here is a working solution (just tried out with MySQL 5.0 on Solaris):

DELIMITER $$

DROP PROCEDURE IF EXISTS upgrade_database_1_0_to_2_0 $$
CREATE PROCEDURE upgrade_database_1_0_to_2_0()
BEGIN

-- rename a table safely
IF NOT EXISTS( (SELECT * FROM information_schema.COLUMNS WHERE TABLE_SCHEMA=DATABASE()
        AND TABLE_NAME='my_old_table_name') ) THEN
    RENAME TABLE 
        my_old_table_name TO my_new_table_name,
END IF;

-- add a column safely
IF NOT EXISTS( (SELECT * FROM information_schema.COLUMNS WHERE TABLE_SCHEMA=DATABASE()
        AND COLUMN_NAME='my_additional_column' AND TABLE_NAME='my_table_name') ) THEN
    ALTER TABLE my_table_name ADD my_additional_column varchar(2048) NOT NULL DEFAULT '';
END IF;

END $$

CALL upgrade_database_1_0_to_2_0() $$

DELIMITER ;

On a first glance it probably looks more complicated than it should, but we have to deal with following problems here:

• IF statements only work in stored procedures, not when run directly, e.g. in mysql client
• more elegant and concise SHOW COLUMNS does not work in stored procedure so have to use INFORMATION_SCHEMA
• the syntax for delimiting statements is strange in MySQL, so you have to redefine the delimiter to be able to create stored procedures. Do not forget to switch the delimiter back!
• INFORMATION_SCHEMA is global for all databases, do not forget to filter on TABLE_SCHEMA=DATABASE(). DATABASE() returns the name of the currently selected database.

There is nothing wrong with returning a void @ResponseBody and you should for POST requests.

Use HTTP status codes to define errors within exception handler routines instead as others are mentioning success status. A normal method as you have will return a response code of 200 which is what you want, any exception handler can then return an error object and a different code (i.e. 500).

Another alternative when anything works is editing /etc/fstab, adding noauto flag and rebooting the machine. The device won't be mounted, and when you're finished doing whatever, remove flag and reboot again.

I agree with Cat Plus Plus's answer. However, if you know this will only be used on Unix-like OSes, you can use external calls to the shell commands mkdir, chmod, and chown. Make sure to pass extra flags to recursively affect directories:

>>> import subprocess
>>> subprocess.check_output(['mkdir', '-p', 'first/second/third']) 
# Equivalent to running 'mkdir -p first/second/third' in a shell (which creates
# parent directories if they do not yet exist).

>>> subprocess.check_output(['chown', '-R', 'dail:users', 'first'])
# Recursively change owner to 'dail' and group to 'users' for 'first' and all of
# its subdirectories.

>>> subprocess.check_output(['chmod', '-R', 'g+w', 'first'])
# Add group write permissions to 'first' and all of its subdirectories.

EDIT I originally used commands, which was a bad choice since it is deprecated and vulnerable to injection attacks. (For example, if a user gave input to create a directory called first/;rm -rf --no-preserve-root /;, one could potentially delete all directories).

EDIT 2 If you are using Python less than 2.7, use check_call instead of check_output. See the subprocess documentation for details.

It is a file ext that some folks used for a while to denote that it was PHP generated HTML. As servers like Apache don't care what you use as a file ext as long as it is mapped to something, you could go ahead and call all your PHP files .jimyBobSmith and it would happily run them. PHTML just happened to be a trend that caught on for a while.

There is many ways to do that but one of them is fiddler

Fiddler Configuration

1. Go to options
2. In HTTPS tab, enable Capture HTTPS Connects and Decrypt HTTPS traffic
3. In Connections tab, enable Allow remote computers to connect
4. Restart fiddler

Android Configuration

1. Connect to same network
2. Modify network settings
3. Add proxy for connection with your PC's IP address ( or hostname ) and default fiddler's port ( 8888 / you can change that in settings )

Now you can see full log from your device in fiddler

Also you can find a full instruction here

With HTML5 specification... It is now possible to put a block-level element inside of an inline element. So now it's perfectly appropriate to put a 'div' or 'h1' inside of an 'a' element.

Find Last Row in a Column OR a Table Column(ListObject) by range

Finding the last row requires:

1. Specifying several parameters (table name, column inside table relative to first column, worksheet, range).
2. May require switching between methods. e.g. if the range is a Table (List Object) or not. Using the wrong search type will return wrong results.

This proposed solution is more general, requires only the range ,less chance of typos and is short (just calling MyLastRow function).

Sub test()
Dim rng As Range
Dim Result As Long
Set rng = Worksheets(1).Range("D4")
Result = MyLastRow(rng)
End Sub

    Function MyLastRow(FirstRow As Range) As Long
    Dim WS As Worksheet
    Dim TableName As String
    Dim ColNumber As Long
    Dim LastRow As Long
    Dim FirstColumnTable As Long
    Dim ColNumberTable As Long
    Set WS = FirstRow.Worksheet
    TableName = GetTableName(FirstRow)
    ColNumber = FirstRow.Column
    
    ''If the table (ListObject) does not start in column "A" we need to calculate the 
    ''first Column table and how many Columns from its beginning the Column is located.
    If TableName <> vbNullString Then
     FirstColumnTable = WS.ListObjects(TableName).ListColumns(1).Range.Column
     ColNumberTable = ColNumber - FirstColumnTable + 1
    End If 

    If TableName = vbNullString Then
    LastRow = WS.Cells(WS.Rows.Count, ColNumber).End(xlUp).Row
    Else
    LastRow = WS.ListObjects(TableName).ListColumns(ColNumberTable).Range.Find( _
               What:="*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
    End If
    MyLastRow = LastRow
    End Function
    
    ''Get Table Name by Cell Range
    Function GetTableName(CellRange As Range) As String
        If CellRange.ListObject Is Nothing Then
            GetTableName = vbNullString
        Else
            GetTableName = CellRange.ListObject.Name
        End If
    End Function

Issue:

When you do are doing:

p => {foo: "bar"}

JavaScript interpreter thinks you are opening a multi-statement code block, and in that block, you have to explicitly mention a return statement.

Solution:

If your arrow function expression has a single statement, then you can use the following syntax:

p => ({foo: "bar", attr2: "some value", "attr3": "syntax choices"})

But if you want to have multiple statements then you can use the following syntax:

p => {return {foo: "bar", attr2: "some value", "attr3": "syntax choices"}}

In above example, first set of curly braces opens a multi-statement code block, and the second set of curly braces is for dynamic objects. In multi-statement code block of arrow function, you have to explicitly use return statements

Dictionary objects allow you to iterate over their items. Also, with pattern matching and the division from __future__ you can do simplify things a bit.

Finally, you can separate your logic from your printing to make things a bit easier to refactor/debug later.

from __future__ import division

    def win_percentages():
        for team, (runs_scored, runs_allowed) in league.iteritems():
            win_percentage = round((runs_scored**2) / ((runs_scored**2)+(runs_allowed**2))*1000)
            yield win_percentage

    for win_percentage in win_percentages():
        print win_percentage

To remove an app from the App Store, deselect all territories in your app's Rights and Pricing section on the App Summary page accessible from the Manage Your Applications module. Your app status will change to Developer Removed from Sale and will be removed from the App Store until you make it available again using the Rights and Pricing section.

If you would like to output array within string using puts, you will get the same result as if you were using print:

puts "#{[0, 1, nil]}":
[0, 1, nil]

But if not withing a quoted string then yes. The only difference is between new line when we use puts.

First initialize Property values

MutablePropertyValues mutablePropertyValues = new MutablePropertyValues();
mutablePropertyValues.add("hostName", details.getHostName());
mutablePropertyValues.add("port", details.getPort());

DefaultListableBeanFactory context = new DefaultListableBeanFactory();
GenericBeanDefinition connectionFactory = new GenericBeanDefinition();
connectionFactory.setBeanClass(Class);
connectionFactory.setPropertyValues(mutablePropertyValues);

context.registerBeanDefinition("beanName", connectionFactory);

Add to the list of beans

ConfigurableListableBeanFactory beanFactory = ((ConfigurableApplicationContext) applicationContext).getBeanFactory();
beanFactory.registerSingleton("beanName", context.getBean("beanName"));

A one-liner for python:

python -c "import random, sys; lines = open(sys.argv[1]).readlines(); random.shuffle(lines); print ''.join(lines)," myFile

And for printing just a single random line:

python -c "import random, sys; print random.choice(open(sys.argv[1]).readlines())," myFile

But see this post for the drawbacks of python's random.shuffle(). It won't work well with many (more than 2080) elements.

I don't think you can do this in XML (at least not in Android), but I've found a good solution posted here that looks like it'd be a great help!

ShapeDrawable.ShaderFactory sf = new ShapeDrawable.ShaderFactory() {
    @Override
    public Shader resize(int width, int height) {
        LinearGradient lg = new LinearGradient(0, 0, width, height,
            new int[]{Color.GREEN, Color.GREEN, Color.WHITE, Color.WHITE},
            new float[]{0,0.5f,.55f,1}, Shader.TileMode.REPEAT);
        return lg;
    }
};

PaintDrawable p=new PaintDrawable();
p.setShape(new RectShape());
p.setShaderFactory(sf);

Basically, the int array allows you to select multiple color stops, and the following float array defines where those stops are positioned (from 0 to 1). You can then, as stated, just use this as a standard Drawable.

Edit: Here's how you could use this in your scenario. Let's say you have a Button defined in XML like so:

<Button
    android:id="@+id/thebutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Press Me!"
    />

You'd then put something like this in your onCreate() method:

Button theButton = (Button)findViewById(R.id.thebutton);
ShapeDrawable.ShaderFactory sf = new ShapeDrawable.ShaderFactory() {
    @Override
    public Shader resize(int width, int height) {
        LinearGradient lg = new LinearGradient(0, 0, 0, theButton.getHeight(),
            new int[] { 
                Color.LIGHT_GREEN, 
                Color.WHITE, 
                Color.MID_GREEN, 
                Color.DARK_GREEN }, //substitute the correct colors for these
            new float[] {
                0, 0.45f, 0.55f, 1 },
            Shader.TileMode.REPEAT);
         return lg;
    }
};
PaintDrawable p = new PaintDrawable();
p.setShape(new RectShape());
p.setShaderFactory(sf);
theButton.setBackground((Drawable)p);

I cannot test this at the moment, this is code from my head, but basically just replace, or add stops for the colors that you need. Basically, in my example, you would start with a light green, fade to white slightly before the center (to give a fade, rather than a harsh transition), fade from white to mid green between 45% and 55%, then fade from mid green to dark green from 55% to the end. This may not look exactly like your shape (Right now, I have no way of testing these colors), but you can modify this to replicate your example.

Edit: Also, the 0, 0, 0, theButton.getHeight() refers to the x0, y0, x1, y1 coordinates of the gradient. So basically, it starts at x = 0 (left side), y = 0 (top), and stretches to x = 0 (we're wanting a vertical gradient, so no left to right angle is necessary), y = the height of the button. So the gradient goes at a 90 degree angle from the top of the button to the bottom of the button.

Edit: Okay, so I have one more idea that works, haha. Right now it works in XML, but should be doable for shapes in Java as well. It's kind of complex, and I imagine there's a way to simplify it into a single shape, but this is what I've got for now:

green_horizontal_gradient.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <corners
        android:radius="3dp"
        />
    <gradient
        android:angle="0"
        android:startColor="#FF63a34a"
        android:endColor="#FF477b36"
        android:type="linear"
        />    
</shape>

half_overlay.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <solid
        android:color="#40000000"
        />
</shape>

layer_list.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android"
    >
    <item
        android:drawable="@drawable/green_horizontal_gradient"
        android:id="@+id/green_gradient"
        />
    <item
        android:drawable="@drawable/half_overlay"
        android:id="@+id/half_overlay"
        android:top="50dp"
        />
</layer-list>

test.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    >
    <TextView
        android:id="@+id/image_test"
        android:background="@drawable/layer_list"
        android:layout_width="fill_parent"
        android:layout_height="100dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:gravity="center"
        android:text="Layer List Drawable!"
        android:textColor="@android:color/white"
        android:textStyle="bold"
        android:textSize="26sp"     
        />
</RelativeLayout>

Okay, so basically I've created a shape gradient in XML for the horizontal green gradient, set at a 0 degree angle, going from the top area's left green color, to the right green color. Next, I made a shape rectangle with a half transparent gray. I'm pretty sure that could be inlined into the layer-list XML, obviating this extra file, but I'm not sure how. But okay, then the kind of hacky part comes in on the layer_list XML file. I put the green gradient as the bottom layer, then put the half overlay as the second layer, offset from the top by 50dp. Obviously you'd want this number to always be half of whatever your view size is, though, and not a fixed 50dp. I don't think you can use percentages, though. From there, I just inserted a TextView into my test.xml layout, using the layer_list.xml file as my background. I set the height to 100dp (twice the size of the offset of the overlay), resulting in the following:

Tada!

One more edit: I've realized you can just embed the shapes into the layer list drawable as items, meaning you don't need 3 separate XML files any more! You can achieve the same result combining them like so:

layer_list.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android"
    >
    <item>
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle"
            >
            <corners
                android:radius="3dp"
                />
            <gradient
                android:angle="0"
                android:startColor="#FF63a34a"
                android:endColor="#FF477b36"
                android:type="linear"
                />    
        </shape>
    </item>
    <item
        android:top="50dp" 
        >
        <shape
            android:shape="rectangle"
            >
            <solid
                android:color="#40000000"
                />
        </shape>            
    </item>
</layer-list>

You can layer as many items as you like this way! I may try to play around and see if I can get a more versatile result through Java.

I think this is the last edit...: Okay, so you can definitely fix the positioning through Java, like the following:

    TextView tv = (TextView)findViewById(R.id.image_test);
    LayerDrawable ld = (LayerDrawable)tv.getBackground();
    int topInset = tv.getHeight() / 2 ; //does not work!
    ld.setLayerInset(1, 0, topInset, 0, 0);
    tv.setBackgroundDrawable(ld);

However! This leads to yet another annoying problem in that you cannot measure the TextView until after it has been drawn. I'm not quite sure yet how you can accomplish this...but manually inserting a number for topInset does work.

I lied, one more edit

Okay, found out how to manually update this layer drawable to match the height of the container, full description can be found here. This code should go in your onCreate() method:

final TextView tv = (TextView)findViewById(R.id.image_test);
        ViewTreeObserver vto = tv.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                LayerDrawable ld = (LayerDrawable)tv.getBackground();
                ld.setLayerInset(1, 0, tv.getHeight() / 2, 0, 0);
            }
        });

And I'm done! Whew! :)

The pdfrw library can do this quite easily, assuming you don't need to preserve bookmarks and annotations, and your PDFs aren't encrypted. cat.py is an example concatenation script, and subset.py is an example page subsetting script.

The relevant part of the concatenation script -- assumes inputs is a list of input filenames, and outfn is an output file name:

from pdfrw import PdfReader, PdfWriter

writer = PdfWriter()
for inpfn in inputs:
    writer.addpages(PdfReader(inpfn).pages)
writer.write(outfn)

As you can see from this, it would be pretty easy to leave out the last page, e.g. something like:

    writer.addpages(PdfReader(inpfn).pages[:-1])

Disclaimer: I am the primary pdfrw author.

Without FileReader, we can use URL.createObjectURL method to get the DOMString that represents the object ( our image file ).

Don't forget to validate image extension.

<input type="file" id="files" multiple />
<div class="image-preview"></div>

let file_input = document.querySelector('#files');
let image_preview = document.querySelector('.image-preview');

const handle_file_preview = (e) => {
  let files = e.target.files;
  let length = files.length;

  for(let i = 0; i < length; i++) {
      let image = document.createElement('img');
      // use the DOMstring for source
      image.src = window.URL.createObjectURL(files[i]);
      image_preview.appendChild(image);
  }
}

file_input.addEventListener('change', handle_file_preview);

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

If what you have configured in your GitLab profile is an SSH public key, then your HTTPS URL would not use it.

Regarding your HTTPS credentials, double-check:

• if the two-factor authentication is disabled, or
• if you have special characters in your username or password, or
• if you have a Git credential helper: git config credential.helper.

Try this link1,link2

@font-face {
        font-family: 'RieslingRegular';

        src: local('Riesling Regular'), local('Riesling'), url('fonts/riesling.ttf')                       format('truetype');
    }

The Invalidate() Method will cause a repaint.

By simplified sequence :

mydata[-(1:3 * 2), ]

By sequence :

mydata[seq(1, nrow(mydata), by = 2) , ]

By negative sequence :

mydata[-seq(2, nrow(mydata), by = 2) , ]

Or if you want to subset by selecting odd numbers:

mydata[which(1:nrow(mydata) %% 2 == 1) , ]

Or if you want to subset by selecting odd numbers, version 2:

mydata[which(1:nrow(mydata) %% 2 != 0) , ]

Or if you want to subset by filtering even numbers out:

mydata[!which(1:nrow(mydata) %% 2 == 0) , ]

Or if you want to subset by filtering even numbers out, version 2:

mydata[!which(1:nrow(mydata) %% 2 != 1) , ]

simply: document.cookie="name=value;path=/";

There is a negative point to it

Now, the cookie will be available to all directories on the domain it is set from. If the website is just one of many at that domain, it’s best not to do this because everyone else will also have access to your cookie information.

This tutorial shows exactly what you need to do: Add options to an HTML select box with javascript

Basically:

 daySelect = document.getElementById('daySelect');
 daySelect.options[daySelect.options.length] = new Option('Text 1', 'Value1');

Here look at how I done it; Jsfiddle

With the Code I put in, I managed to get it working on Webkit (Chrome/Safari) and Firefox. I don't know if it works with the latest version of Opera. Yes it does work under the latest version of Opera.

Here is the code. Integrate it according to your need. I hope it will help.

Even if a builtin way existed, it wouldn't validate it as greater than today and it would differ very little from a substring call. I wouldn't worry about it.

The code is very long so I can't paste all the code.

There could be any number of reasons why your code doesn't work. Maybe you declared the button variables twice so you aren't actually changing enabling/disabling the button like you think you are. Maybe you are blocking the EDT.

You need to create a SSCCE to post on the forum.

So its up to you to isolate the problem. Start with a simple frame thas two buttons and see if your code works. Once you get that working, then try starting a Thread that simply sleeps for 10 seconds to see if it still works.

i know this is an old post, but wanted to share how i solved the same problem.

My image was inheriting a float:left from a parent class. By setting float:none I was able to make margin:0 auto and display: block work properly. Hope it may help someone in the future.

If you are on Mac OS X just use Simulator. I don't know if it is available by default but it looks like it is a part of the Xcode suite.

Anyway it is free and really useful, it allows you to simulate many popular Apple devices:

You can use "group by" + "orderby". See LINQ 101 for details

var list = new List<string> {"a", "b", "a", "c", "a", "b"};
var q = from x in list
        group x by x into g
        let count = g.Count()
        orderby count descending
        select new {Value = g.Key, Count = count};
foreach (var x in q)
{
    Console.WriteLine("Value: " + x.Value + " Count: " + x.Count);
}

In response to this post (now deleted):

If you have a list of some custom objects then you need to use custom comparer or group by specific property.

Also query can't display result. Show us complete code to get a better help.

Based on your latest update:

You have this line of code:

group xx by xx into g

Since xx is a custom object system doesn't know how to compare one item against another. As I already wrote, you need to guide compiler and provide some property that will be used in objects comparison or provide custom comparer. Here is an example:

Note that I use Foo.Name as a key - i.e. objects will be grouped based on value of Name property.

There is one catch - you treat 2 objects to be duplicate based on their names, but what about Id ? In my example I just take Id of the first object in a group. If your objects have different Ids it can be a problem.

//Using extension methods
var q = list.GroupBy(x => x.Name)
            .Select(x => new {Count = x.Count(), 
                              Name = x.Key, 
                              ID = x.First().ID})
            .OrderByDescending(x => x.Count);

//Using LINQ
var q = from x in list
        group x by x.Name into g
        let count = g.Count()
        orderby count descending
        select new {Name = g.Key, Count = count, ID = g.First().ID};

foreach (var x in q)
{
    Console.WriteLine("Count: " + x.Count + " Name: " + x.Name + " ID: " + x.ID);
}

git checkout master

That's result something like this:

Warning: you are leaving 2 commits behind, not connected to
any of your branches:

If you want to keep them by creating a new branch, this may be a good time to do so with:
git branch new_branch_name 1e7822f25e376d6a1182bb86a0adf3a774920e1e

So, let's do it:

git merge 1e7822f25e376d6a1182bb86a0adf3a774920e1e

To add to the above post^^:

If either of the services are not running, it might simply just be because they need to be installed/configured. This is easy to do straight from the WampManager Icon.

 WampManager Icon -> Apache -> Service -> Install Service

You should get a command prompt pop-up if port 80 is free (if not, see above post):

      'Your port 80 is available. Install will proceed.

       Press Enter to continue...'

WampManager Icon -> MySQL -> Service -> Install Service

WampManager Icon -> Restart All Services

The icon should now turn green :)

This is such a common problem, especially in GUI applications, that I'm surprised there isn't a BCL class to do this out of the box. Here's how I do it.

public static class ReflectiveEnumerator
{
    static ReflectiveEnumerator() { }

    public static IEnumerable<T> GetEnumerableOfType<T>(params object[] constructorArgs) where T : class, IComparable<T>
    {
        List<T> objects = new List<T>();
        foreach (Type type in 
            Assembly.GetAssembly(typeof(T)).GetTypes()
            .Where(myType => myType.IsClass && !myType.IsAbstract && myType.IsSubclassOf(typeof(T))))
        {
            objects.Add((T)Activator.CreateInstance(type, constructorArgs));
        }
        objects.Sort();
        return objects;
    }
}

A few notes:

• Don't worry about the "cost" of this operation - you're only going to be doing it once (hopefully) and even then it's not as slow as you'd think.
• You need to use Assembly.GetAssembly(typeof(T)) because your base class might be in a different assembly.
• You need to use the criteria type.IsClass and !type.IsAbstract because it'll throw an exception if you try to instantiate an interface or abstract class.
• I like forcing the enumerated classes to implement IComparable so that they can be sorted.
• Your child classes must have identical constructor signatures, otherwise it'll throw an exception. This typically isn't a problem for me.

The reason that this doesn't work is because the variable doesn't change with the textbox. When it initially runs the code it gets the value of the textbox, but afterwards it isn't ever called again. However, when you define the variable in the function, every time that you call the function the variable updates. Then it alerts the variable which is now equal to the textbox's input.

I had the same problem but with a listView.... i solved it because i was using a wrong R.id.listView that list View needed to have a value, in my case it was strings that i saved on listView2... so the right code was R.id.listView2

If you're using xml.etree.ElementTree.parse to parse from a file, then you can use xml.etree.ElementTree.fromstring to parse from text.

See xml.etree.ElementTree

I am reading some data from a file using read. Here I am reading data in a 2d char pointer but the method is the same for the 1d also. Just read character by character and do not worry about the exceptions because the condition in the while loop is handling the exceptions :D

  while ( (n = read(fd, buffer,1)) > 0 )
{   

if(buffer[0] == '\n')
{
  r++;
  char**tempData=(char**)malloc(sizeof(char*)*r);

  for(int a=0;a<r;a++)
  {
    tempData[a]=(char*)malloc(sizeof(char)*BUF_SIZE);
    memset(tempData[a],0,BUF_SIZE);
  }

  for(int a=0;a<r-1;a++)
  {
    strcpy(tempData[a],data[a]);
  }

   data=tempData;

   c=0;
}

else
{
  data[r-1][c]=buffer[0];
  c++;
  buffer[1]='\0';
}

   }

In Kotlin List can be converted into ArrayList through passing it as a constructor parameter.

ArrayList(list)

Alternatively, you can use the matplotlib.pyplot.axis() function, which allows you inverting any of the plot axis

ax = matplotlib.pyplot.axis()
matplotlib.pyplot.axis((ax[0],ax[1],ax[3],ax[2]))

Or if you prefer to only reverse the X-axis, then

matplotlib.pyplot.axis((ax[1],ax[0],ax[2],ax[3]))

Indeed, you can invert both axis:

matplotlib.pyplot.axis((ax[1],ax[0],ax[3],ax[2]))

I had the same problem. Here are the steps for Windows 10 users.

Open CMD: win+r then type cmd. Now,

1. Type pip install virtualenv
2. Create a Virtual Environment, Type virtualenv testopencv
3. Get Inside testopencv, Type cd testopencv
4. Activate the Virtual Environment, Type .\Scripts\activate
5. Now Install Opencv, Type pip install opencv-contrib-python --upgrade
6. Let's test Opencv, Type Python then import cv2 hit enter then type print(cv2.__version__) to check if its installed

Now, open a new cmd, win + r then type cmd, repeat step 6. If it gives you an error.

Go inside the testopencv folder, inside lib. Copy everything, go to your python directory, inside lib folder paste it and skip that are already present.

Again open a new cmd, repeat Step 6.

Hope it helps.

I've just created a javascript shim to achieve this goal. Take a look if you want, it's a proof-of-concept, but take care: it's a early version and still needs some work.

I think its worth referencing this similar answer: https://stackoverflow.com/a/5288804/64313

Here is a another quick solution. There are other variations possible on this using the <available> tag:

# exit with failure if no files are found
<property name="file" value="${some.path}/some.txt" />
<fail message="FILE NOT FOUND: ${file}">
    <condition><not>
        <available file="${file}" />
    </not></condition>
</fail>

You need to "clear" the float after every 6 images. So with your current code, change the styles for containerdivNewLine to:

.containerdivNewLine { clear: both; float: left; display: block; position: relative; }
