If you can update your connector to a version, which supports the new authentication plugin of MySQL 8, then do that. If that is not an option for some reason, change the default authentication method of your database user to native.

Return ABDeadlineType from repository:

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

and then convert to DeadlineType. Manually or use mapstruct.

Or call constructor from @Query annotation:

public interface DeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {

    @Query("select new package.DeadlineType(a.id, a.code) from ABDeadlineType a ")
    List<DeadlineType> findAllSummarizedBy();
}

Or use @Projection:

@Projection(name = "deadline", types = { ABDeadlineType.class })
public interface DeadlineType {

    @Value("#{target.id}")
    String getId();

    @Value("#{target.code}")
    String getText();

}

Update: Spring can work without @Projection annotation:

public interface DeadlineType {
    String getId();    
    String getText();
}

Try this, to call your code in ngOnInit()

someMethod() // emitted method call from output

ngOnInit(){
  someMethod(); // call here your error will be gone
}

I had the same problem with Pool() in Python 3.6.3.

Error received: TypeError: can't pickle _thread.RLock objects

Let's say we want to add some number num_to_add to each element of some list num_list in parallel. The code is schematically like this:

class DataGenerator:
    def __init__(self, num_list, num_to_add)
        self.num_list = num_list # e.g. [4,2,5,7]
        self.num_to_add = num_to_add # e.g. 1 

        self.run()

    def run(self):
        new_num_list = Manager().list()

        pool = Pool(processes=50)
        results = [pool.apply_async(run_parallel, (num, new_num_list)) 
                      for num in num_list]
        roots = [r.get() for r in results]
        pool.close()
        pool.terminate()
        pool.join()

    def run_parallel(self, num, shared_new_num_list):
        new_num = num + self.num_to_add # uses class parameter
        shared_new_num_list.append(new_num)

The problem here is that self in function run_parallel() can't be pickled as it is a class instance. Moving this parallelized function run_parallel() out of the class helped. But it's not the best solution as this function probably needs to use class parameters like self.num_to_add and then you have to pass it as an argument.

Solution:

def run_parallel(num, shared_new_num_list, to_add): # to_add is passed as an argument
    new_num = num + to_add
    shared_new_num_list.append(new_num)

class DataGenerator:
    def __init__(self, num_list, num_to_add)
        self.num_list = num_list # e.g. [4,2,5,7]
        self.num_to_add = num_to_add # e.g. 1

        self.run()

    def run(self):
        new_num_list = Manager().list()

        pool = Pool(processes=50)
        results = [pool.apply_async(run_parallel, (num, new_num_list, self.num_to_add)) # num_to_add is passed as an argument
                      for num in num_list]
        roots = [r.get() for r in results]
        pool.close()
        pool.terminate()
        pool.join()

Other suggestions above didn't help me.

Use getCellType()

switch (cell.getCellType()) {
   case BOOLEAN :
                 //To-do
                 break;
   case NUMERIC:
                 //To-do
                 break;
   case STRING:
                 //To-do
                 break;
}

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

You can use the spread operator to re-assign props with a standard functional component. The thing I like about this approach is that you can mix required props with optional ones that have a default value.

interface MyProps {
   text: string;
   optionalText?: string;
}

const defaultProps = {
   optionalText = "foo";
}

const MyComponent = (props: MyProps) => {
   props = { ...defaultProps, ...props }
}

I got the same error and changing the following

SessionFactory sessionFactory =
    new Configuration().configure().buildSessionFactory();

to this

SessionFactory sessionFactory =
    new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();

worked for me.

there is component ready to use (rc5 compatible) ng2-steps which uses Compiler to inject component to step container and service for wiring everything together (data sync)

    import { Directive , Input, OnInit, Compiler , ViewContainerRef } from '@angular/core';

import { StepsService } from './ng2-steps';

@Directive({
  selector:'[ng2-step]'
})
export class StepDirective implements OnInit{

  @Input('content') content:any;
  @Input('index') index:string;
  public instance;

  constructor(
    private compiler:Compiler,
    private viewContainerRef:ViewContainerRef,
    private sds:StepsService
  ){}

  ngOnInit(){
    //Magic!
    this.compiler.compileComponentAsync(this.content).then((cmpFactory)=>{
      const injector = this.viewContainerRef.injector;
      this.viewContainerRef.createComponent(cmpFactory, 0,  injector);
    });
  }

}

In sequelize you can easily add order by clauses.

exports.getStaticCompanies = function () {
    return Company.findAll({
        where: {
            id: [46128, 2865, 49569,  1488,   45600,   61991,  1418,  61919,   53326,   61680]
        }, 
        // Add order conditions here....
        order: [
            ['id', 'DESC'],
            ['name', 'ASC'],
        ],
        attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at']
    });
};

See how I've added the order array of objects?

order: [
      ['COLUMN_NAME_EXAMPLE', 'ASC'], // Sorts by COLUMN_NAME_EXAMPLE in ascending order
],

Edit:

You might have to order the objects once they've been recieved inside the .then() promise. Checkout this question about ordering an array of objects based on a custom order:

How do I sort an array of objects based on the ordering of another array?

For me using ngAfterViewInit instead of ngOnInit fixed the issue :

export class AppComponent implements OnInit {
  @ViewChild('video') video;
  ngOnInit(){
    // <-- in here video is undefined
  }
  public ngAfterViewInit()
  {
    console.log(this.video.nativeElement) // <-- you can access it here
  }
}

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

Things to know in general:

1. Key != Password
   • SecretKeySpec expects a key, not a password. See below
2. It might be due to a policy restriction that prevents using 32 byte keys. See other answer on that

In your case

The problem is number 1: you are passing the password instead of the key.

AES only supports key sizes of 16, 24 or 32 bytes. You either need to provide exactly that amount or you derive the key from what you type in.

There are different ways to derive the key from a passphrase. Java provides a PBKDF2 implementation for such a purpose.

I used erickson's answer to paint a complete picture (only encryption, since the decryption is similar, but includes splitting the ciphertext):

SecureRandom random = new SecureRandom();
byte[] salt = new byte[16];
random.nextBytes(salt);

KeySpec spec = new PBEKeySpec("password".toCharArray(), salt, 65536, 256); // AES-256
SecretKeyFactory f = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
byte[] key = f.generateSecret(spec).getEncoded();
SecretKeySpec keySpec = new SecretKeySpec(key, "AES");

byte[] ivBytes = new byte[16];
random.nextBytes(ivBytes);
IvParameterSpec iv = new IvParameterSpec(ivBytes);

Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
c.init(Cipher.ENCRYPT_MODE, keySpec, iv);
byte[] encValue = c.doFinal(valueToEnc.getBytes());

byte[] finalCiphertext = new byte[encValue.length+2*16];
System.arraycopy(ivBytes, 0, finalCiphertext, 0, 16);
System.arraycopy(salt, 0, finalCiphertext, 16, 16);
System.arraycopy(encValue, 0, finalCiphertext, 32, encValue.length);

return finalCiphertext;

Other things to keep in mind:

• Always use a fully qualified Cipher name. AES is not appropriate in such a case, because different JVMs/JCE providers may use different defaults for mode of operation and padding. Use AES/CBC/PKCS5Padding. Don't use ECB mode, because it is not semantically secure.
• If you don't use ECB mode then you need to send the IV along with the ciphertext. This is usually done by prefixing the IV to the ciphertext byte array. The IV is automatically created for you and you can get it through cipherInstance.getIV().
• Whenever you send something, you need to be sure that it wasn't altered along the way. It is hard to implement a encryption with MAC correctly. I recommend you to use an authenticated mode like CCM or GCM.

The correct config key is retention.ms

$ bin/kafka-topics.sh --zookeeper zk.prod.yoursite.com --alter --topic as-access --config retention.ms=86400000
Updated config for topic "my-topic".

You could just specify the following property -Dhttps.protocols=TLSv1.1,TLSv1.2 at your server which configures the JVM to specify which TLS protocol version should be used during all https connections from client.

Resources in Scala work exactly as they do in Java. It is best to follow the Java best practices and put all resources in src/main/resources and src/test/resources.

Example folder structure:

testing_styles/
+-- build.sbt
+-- src
¦   +-- main
¦       +-- resources
¦       ¦   +-- readme.txt

Scala 2.12.x && 2.13.x reading a resource

To read resources the object Source provides the method fromResource.

import scala.io.Source
val readmeText : Iterator[String] = Source.fromResource("readme.txt").getLines

reading resources prior 2.12 (still my favourite due to jar compatibility)

To read resources you can use getClass.getResource and getClass.getResourceAsStream .

val stream: InputStream = getClass.getResourceAsStream("/readme.txt")
val lines: Iterator[String] = scala.io.Source.fromInputStream( stream ).getLines

nicer error feedback (2.12.x && 2.13.x)

To avoid undebuggable Java NPEs, consider:

import scala.util.Try
import scala.io.Source
import java.io.FileNotFoundException

object Example {

  def readResourceWithNiceError(resourcePath: String): Try[Iterator[String]] = 
    Try(Source.fromResource(resourcePath).getLines)
      .recover(throw new FileNotFoundException(resourcePath))
 }

good to know

Keep in mind that getResourceAsStream also works fine when the resources are part of a jar, getResource, which returns a URL which is often used to create a file can lead to problems there.

in Production

In production code I suggest to make sure that the source is closed again.

The .join() function is using the index of the passed as argument dataset, so you should use set_index or use .merge function instead.

Please find the two examples that should work in your case:

join_df = LS_sgo.join(MSU_pi.set_index('mukey'), on='mukey', how='left')

or

join_df = df_a.merge(df_b, on='mukey', how='left')

This seems to happen from time to time with programs that are very sensitive to command lines, but one option is to just use the DOS path instead of the Windows path. This means that C:\Program Files\ would resolve to C:\PROGRA~1\ and generally avoid any issues with spacing.

To get the short path you can create a quick Batch file that echos the short path:

@ECHO OFF
echo %~s1

Which is then called as follows:

C:\>shortPath.bat "C:\Program Files"
C:\PROGRA~1

I added the spring folder to the build path and, after clean&build, it worked.

If you're using spring boot with starters - this dependency adds both tomcat-embed-el and hibernate-validator dependencies:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

In the last version of spring boot 2.1.1.RELEASE, it is simple as :

@RunWith(SpringRunner.class)
@SpringBootTest(classes = SampleApplication.class)
public class CustomerRepositoryIntegrationTest {

    @Autowired
    CustomerRepository repository;

    @Test
    public void myTest() throws Exception {

        Customer customer = new Customer();
        customer.setId(100l);
        customer.setFirstName("John");
        customer.setLastName("Wick");

        repository.save(customer);

        List<?> queryResult = repository.findByLastName("Wick");

        assertFalse(queryResult.isEmpty());
        assertNotNull(queryResult.get(0));
    }
}

Complete code:

Use pngcrush to remove the incorrect sRGB profile from the png file:

pngcrush -ow -rem allb -reduce file.png

• -ow will overwrite the input file
• -rem allb will remove all ancillary chunks except tRNS and gAMA
• -reduce does lossless color-type or bit-depth reduction

In the console output you should see Removed the sRGB chunk, and possibly more messages about chunk removals. You will end up with a smaller, optimized PNG file. As the command will overwrite the original file, make sure to create a backup or use version control.

When I had this problem, I had literally just forgot to fill in a parameter value in the XAML of the code.

For some reason though, the exception would send me to the CS of the WPF program rather than the XAML. No idea why.

You are trying to read xls with explicit implementation poi classes for xlsx.

G:\Selenium Jar Files\TestData\Data.xls

Either use HSSFWorkbook and HSSFSheet classes or make your implementation more generic by using shared interfaces, like;

Change:

XSSFWorkbook workbook = new XSSFWorkbook(file);

To:

 org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(file);

And Change:

XSSFSheet sheet = workbook.getSheetAt(0);

To:

org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);

Freddy's answer helped me a lot to get this working. For the sake of completeness here's how you could implement hashing of the token:

private string ComputeHash(Guid input)
{
    byte[] source = input.ToByteArray();

    var encoder = new SHA256Managed();
    byte[] encoded = encoder.ComputeHash(source);

    return Convert.ToBase64String(encoded);
}

In CreateAsync:

var guid = Guid.NewGuid();
...
_refreshTokens.TryAdd(ComputeHash(guid), refreshTokenTicket);
context.SetToken(guid.ToString());

ReceiveAsync:

public async Task ReceiveAsync(AuthenticationTokenReceiveContext context)
{
    Guid token;

    if (Guid.TryParse(context.Token, out token))
    {
        AuthenticationTicket ticket;

        if (_refreshTokens.TryRemove(ComputeHash(token), out ticket))
        {
            context.SetTicket(ticket);
        }
    }
}

As Mingyu pointed out, there is a problem in formatting. Other than that, I would strongly recommend not using the Derived class's name while calling super() since it makes your code inflexible (code maintenance and inheritance issues). In Python 3, Use super().__init__ instead. Here is the code after incorporating these changes :

class Car(object):
    condition = "new"

    def __init__(self, model, color, mpg):
        self.model = model
        self.color = color
        self.mpg   = mpg

class ElectricCar(Car):

    def __init__(self, battery_type, model, color, mpg):
        self.battery_type=battery_type
        super().__init__(model, color, mpg)

Thanks to Erwin Mayer for pointing out the issue in using __class__ with super()

When doing Flask Basic auth I got this error and then I realized I had wrapped_view(**kwargs) and it worked after changing it to wrapped_view(*args, **kwargs).

I Found that removing the references to Entity Framework and installing the latest version of Entity Framework from NuGet fixed the issue. It recreates all the required entries for you during install.

A repair of the DotNetCore hosting bundle did the trick for me. :/

With join - interpreter will wait until your process get completed or terminated

>>> from threading import Thread
>>> import time
>>> def sam():
...   print 'started'
...   time.sleep(10)
...   print 'waiting for 10sec'
... 
>>> t = Thread(target=sam)
>>> t.start()
started

>>> t.join() # with join interpreter will wait until your process get completed or terminated
done?   # this line printed after thread execution stopped i.e after 10sec
waiting for 10sec
>>> done?

without join - interpreter wont wait until process get terminated,

>>> t = Thread(target=sam)
>>> t.start()
started
>>> print 'yes done' #without join interpreter wont wait until process get terminated
yes done
>>> waiting for 10sec

For debugging when I start java add like mentioned:

-Djavax.net.debug=ssl

then you can see that the browser tried to use TLSv1 and Jetty 9.1.3 was talking TLSv1.2 so they were not communicating. That's Firefox. Chrome wanted SSLv3 so I added that also.

sslContextFactory.setIncludeProtocols( "TLSv1", "SSLv3" );  <-- Fix
sslContextFactory.setRenegotiationAllowed(true);   <-- added don't know if helps anything.

I did not do most of the other stuff the orig poster did:

        .getDefaultAlgorithm());

I had the same issue. I solved it by using the following steps(Editor: IntelliJ):

1. View -> Tool Windows -> Maven Project. Opens your projects in a sub-window.
2. Click on the arrow next to your project.
3. Click on the lifecycle.
4. Click on clean.

This question is quite dated yet I wanted to leave an answer that leverages the current version of the language. Unfortunately static classes still don't exist in TypeScript however you can write a class that behaves similar with only a small overhead using a private constructor which prevents instantiation of classes from outside.

class MyStaticClass {
    public static readonly property: number = 42;
    public static myMethod(): void { /* ... */ }
    private constructor() { /* noop */ }
}

This snippet will allow you to use "static" classes similar to the C# counterpart with the only downside that it is still possible to instantiate them from inside. Fortunately though you cannot extend classes with private constructors.

The message you mention is quite clear:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

SLF4J API could not find a binding, and decided to default to a NOP implementation. In your case slf4j-log4j12.jar was somehow not visible when the LoggerFactory class was loaded into memory, which is admittedly very strange. What does "mvn dependency:tree" tell you?

The various dependency declarations may not even be directly at cause here. I strongly suspect that a pre-1.6 version of slf4j-api.jar is being deployed without your knowledge.

Addition to @jwize's answer

Because angular.element(document).injector() was giving error injector is not defined So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.

  function compileAngularElement( elSelector) {

        var elSelector = (typeof elSelector == 'string') ? elSelector : null ;  
            // The new element to be added
        if (elSelector != null ) {
            var $div = $( elSelector );

                // The parent of the new element
                var $target = $("[ng-app]");

              angular.element($target).injector().invoke(['$compile', function ($compile) {
                        var $scope = angular.element($target).scope();
                        $compile($div)($scope);
                        // Finally, refresh the watch expressions in the new element
                        $scope.$apply();
                    }]);
            }

        }

use it by passing just new element's selector. like this

compileAngularElement( '.user' ) ; 

I know it's an old question but I want to help. You can put the transactional annotation on the service method you need, in this case findTopicByID(id) should have

@Transactional(propagation=Propagation.REQUIRED, readOnly=true, noRollbackFor=Exception.class)

more info about this annotation can be found here

About the other solutions:

fetch = FetchType.EAGER 

is not a good practice, it should be used ONLY if necessary.

Hibernate.initialize(topics.getComments());

The hibernate initializer binds your classes to the hibernate technology. If you are aiming to be flexible is not a good way to go.

Hope it helps

You need to update MVC.

1. Go to Tools -> NuGet Package Manager -> Manage NuGet Packages for Solution
2. Click on "Updates"

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

UPDATE 23/Dec/2015: Since this answer seems to be getting a lot of upvotes, I've updated it to fix silly bugs and to generally improve the code based upon comments and feedback. See the end of the post for a list of specific improvements.

As other people have said, Cryptography is not simple so it's best to avoid "rolling your own" encryption algorithm.

You can, however, "roll your own" wrapper class around something like the built-in RijndaelManaged cryptography class.

Rijndael is the algorithmic name of the current Advanced Encryption Standard, so you're certainly using an algorithm that could be considered "best practice".

The RijndaelManaged class does indeed normally require you to "muck about" with byte arrays, salts, keys, initialization vectors etc. but this is precisely the kind of detail that can be somewhat abstracted away within your "wrapper" class.

The following class is one I wrote a while ago to perform exactly the kind of thing you're after, a simple single method call to allow some string-based plaintext to be encrypted with a string-based password, with the resulting encrypted string also being represented as a string. Of course, there's an equivalent method to decrypt the encrypted string with the same password.

Unlike the first version of this code, which used the exact same salt and IV values every time, this newer version will generate random salt and IV values each time. Since salt and IV must be the same between the encryption and decryption of a given string, the salt and IV is prepended to the cipher text upon encryption and extracted from it again in order to perform the decryption. The result of this is that encrypting the exact same plaintext with the exact same password gives and entirely different ciphertext result each time.

The "strength" of using this comes from using the RijndaelManaged class to perform the encryption for you, along with using the Rfc2898DeriveBytes function of the System.Security.Cryptography namespace which will generate your encryption key using a standard and secure algorithm (specifically, PBKDF2) based upon the string-based password you supply. (Note this is an improvement of the first version's use of the older PBKDF1 algorithm).

Finally, it's important to note that this is still unauthenticated encryption. Encryption alone provides only privacy (i.e. message is unknown to 3rd parties), whilst authenticated encryption aims to provide both privacy and authenticity (i.e. recipient knows message was sent by the sender).

Without knowing your exact requirements, it's difficult to say whether the code here is sufficiently secure for your needs, however, it has been produced to deliver a good balance between relative simplicity of implementation vs "quality". For example, if your "receiver" of an encrypted string is receiving the string directly from a trusted "sender", then authentication may not even be necessary.

If you require something more complex, and which offers authenticated encryption, check out this post for an implementation.

Here's the code:

using System;
using System.Text;
using System.Security.Cryptography;
using System.IO;
using System.Linq;

namespace EncryptStringSample
{
    public static class StringCipher
    {
        // This constant is used to determine the keysize of the encryption algorithm in bits.
        // We divide this by 8 within the code below to get the equivalent number of bytes.
        private const int Keysize = 256;

        // This constant determines the number of iterations for the password bytes generation function.
        private const int DerivationIterations = 1000;

            return randomBytes;

}

The above class can be used quite simply with code similar to the following:

using System;

namespace EncryptStringSample
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Please enter a password to use:");
            string password = Console.ReadLine();
            Console.WriteLine("Please enter a string to encrypt:");
            string plaintext = Console.ReadLine();
            Console.WriteLine("");

            Console.WriteLine("Your encrypted string is:");
            string encryptedstring = StringCipher.Encrypt(plaintext, password);
            Console.WriteLine(encryptedstring);
            Console.WriteLine("");

            Console.WriteLine("Your decrypted string is:");
            string decryptedstring = StringCipher.Decrypt(encryptedstring, password);
            Console.WriteLine(decryptedstring);
            Console.WriteLine("");

            Console.WriteLine("Press any key to exit...");
            Console.ReadLine();
        }
    }
}

(You can download a simple VS2013 sample solution (which includes a few unit tests) here).

UPDATE 23/Dec/2015: The list of specific improvements to the code are:

• Fixed a silly bug where encoding was different between encrypting and decrypting. As the mechanism by which salt & IV values are generated has changed, encoding is no longer necessary.
• Due to the salt/IV change, the previous code comment that incorrectly indicated that UTF8 encoding a 16 character string produces 32 bytes is no longer applicable (as encoding is no longer necessary).
• Usage of the superseded PBKDF1 algorithm has been replaced with usage of the more modern PBKDF2 algorithm.
• The password derivation is now properly salted whereas previously it wasn't salted at all (another silly bug squished).

Introduction: I have encountered such problem when was testing my fist network app. I created: Client and Server then I ran client and suddenly exception was thrown, indeed it blocks the connection, because the port is not being listened!

Error: My port was not listened by the server, because server was down.

Solution: Run the Server first, so the port will be listened by server and once client tries to connect the server will handle that.

I was having a problem getting my ASP.NET 5.0/MVC 6 app to serve static binary file types or browse virtual directories. It looks like this is now done in Configure() at startup. See http://docs.asp.net/en/latest/fundamentals/static-files.html for a quick primer.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

Let me guess

Your initial declaration of class PUBLICClass was not public, then you made it `Public', can you try to clean and rebuild your project ?

That file has a listen-port element - that should be what you need to change, although it is currently set to 8080, not 7001.

while doing performance testing, the measure i go by is RPS, that is how many requests per second can the server serve within acceptable latency.

theoretically one server can only run as many requests concurrently as number of cores on it..

It doesn't look like the problem is ASP.net's threading model, since it can potentially serve thousands of rps. It seems like the problem might be your application. Are you using any synchronization primitives ?

also whats the latency on your web services, are they very quick to respond (within microseconds), if not then you might want to consider asynchronous calls, so you dont end up blocking

If this doesnt yeild something, then you might want to profile your code using visual studio or redgate profiler

raw_input is your helper here. From documentation -

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

So your code will basically look like this.

num_array = list()
num = raw_input("Enter how many elements you want:")
print 'Enter numbers in array: '
for i in range(int(num)):
    n = raw_input("num :")
    num_array.append(int(n))
print 'ARRAY: ',num_array

P.S: I have typed all this free hand. Syntax might be wrong but the methodology is correct. Also one thing to note is that, raw_input does not do any type checking, so you need to be careful...

Change the node to and create a file, packages.xsd, in the same folder (and include it in the project) with the following contents:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
      targetNamespace="urn:packages" xmlns="urn:packages">

Pretty sure that this exception is thrown when the Excel file is either password protected or the file itself is corrupted. If you just want to read a .xlsx file, try my code below. It's a lot more shorter and easier to read.

import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.Sheet;
//.....

static final String excelLoc = "C:/Documents and Settings/Users/Desktop/testing.xlsx";

public static void ReadExcel() {
InputStream inputStream = null;
   try {
        inputStream = new FileInputStream(new File(excelLoc));
        Workbook wb = WorkbookFactory.create(inputStream);
        int numberOfSheet = wb.getNumberOfSheets();

        for (int i = 0; i < numberOfSheet; i++) {
             Sheet sheet = wb.getSheetAt(i);
             //.... Customize your code here
             // To get sheet name, try -> sheet.getSheetName()
        }
   } catch {}
}

Why hasn't anyone suggested Activator.CreateInstance ?

GCC does actually optimize a*a*a*a*a*a to (a*a*a)*(a*a*a) when a is an integer. I tried with this command:

$ echo 'int f(int x) { return x*x*x*x*x*x; }' | gcc -o - -O2 -S -masm=intel -x c -

There are a lot of gcc flags but nothing fancy. They mean: Read from stdin; use O2 optimization level; output assembly language listing instead of a binary; the listing should use Intel assembly language syntax; the input is in C language (usually language is inferred from input file extension, but there is no file extension when reading from stdin); and write to stdout.

Here's the important part of the output. I've annotated it with some comments indicating what's going on in the assembly language:

; x is in edi to begin with.  eax will be used as a temporary register.
mov  eax, edi  ; temp = x
imul eax, edi  ; temp = x * temp
imul eax, edi  ; temp = x * temp
imul eax, eax  ; temp = temp * temp

I'm using system GCC on Linux Mint 16 Petra, an Ubuntu derivative. Here's the gcc version:

$ gcc --version
gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1

As other posters have noted, this option is not possible in floating point, because floating point arithmetic is not associative.

Invoke-Expression, also aliased as iex. The following will work on your examples #2 and #3:

iex $command

Some strings won't run as-is, such as your example #1 because the exe is in quotes. This will work as-is, because the contents of the string are exactly how you would run it straight from a Powershell command prompt:

$command = 'C:\somepath\someexe.exe somearg'
iex $command

However, if the exe is in quotes, you need the help of & to get it running, as in this example, as run from the commandline:

>> &"C:\Program Files\Some Product\SomeExe.exe" "C:\some other path\file.ext"

And then in the script:

$command = '"C:\Program Files\Some Product\SomeExe.exe" "C:\some other path\file.ext"'
iex "& $command"

Likely, you could handle nearly all cases by detecting if the first character of the command string is ", like in this naive implementation:

function myeval($command) {
    if ($command[0] -eq '"') { iex "& $command" }
    else { iex $command }
}

But you may find some other cases that have to be invoked in a different way. In that case, you will need to either use try{}catch{}, perhaps for specific exception types/messages, or examine the command string.

If you always receive absolute paths instead of relative paths, you shouldn't have many special cases, if any, outside of the 2 above.

I've just checked and i have the same code as you and it works perferctly. The only difference is how i fill my List for the params :

I use a : ArrayList<BasicNameValuePair> params

and fill it this way :

 params.add(new BasicNameValuePair("apikey", apikey);

I do not use any JSONObject to send params to the webservices.

Are you obliged to use the JSONObject ?

The web.config transforms that are part of Visual Studio 2010 use XSLT in order to "transform" the current web.config file into its .Debug or .Release version.

In your .Debug/.Release files, you need to add the following parameter in your connection string fields:

xdt:Transform="SetAttributes" xdt:Locator="Match(name)"

This will cause each connection string line to find the matching name and update the attributes accordingly.

Note: You won't have to worry about updating your providerName parameter in the transform files, since they don't change.

Here's an example from one of my apps. Here's the web.config file section:

<connectionStrings>
      <add name="EAF" connectionString="[Test Connection String]" />
</connectionString>

And here's the web.config.release section doing the proper transform:

<connectionStrings>
      <add name="EAF" connectionString="[Prod Connection String]"
           xdt:Transform="SetAttributes"
           xdt:Locator="Match(name)" />
</connectionStrings>

One added note: Transforms only occur when you publish the site, not when you simply run it with F5 or CTRL+F5. If you need to run an update against a given config locally, you will have to manually change your Web.config file for this.

For more details you can see the MSDN documentation

https://msdn.microsoft.com/en-us/library/dd465326(VS.100).aspx

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

I've figured it out, you can add to request mapping produces = "text/plain;charset=UTF-8"

@RequestMapping(value = "/rest/create/document", produces = "text/plain;charset=UTF-8")
@ResponseBody
public void create(Document document, HttpServletRespone respone) throws UnsupportedEncodingException {

    Document newDocument = DocumentService.create(Document);

    return jsonSerializer.serialize(newDocument);
}

see this blog post for more details on the solution

This method is the simplest way for beginners to control Layouts rendering in your ASP.NET MVC application. We can identify the controller and render the Layouts as par controller, to do this we can write our code in _ViewStart file in the root directory of the Views folder. Following is an example shows how it can be done.

@{
    var controller = HttpContext.Current.Request.RequestContext.RouteData.Values["Controller"].ToString();
    string cLayout = "";

    if (controller == "Webmaster")
        cLayout = "~/Views/Shared/_WebmasterLayout.cshtml";
    else
        cLayout = "~/Views/Shared/_Layout.cshtml";

    Layout = cLayout;
}

The web.xml file is the deployment descriptor for a Servlet-based Java web application (which most Java web apps are). Among other things, it declares which Servlets exist and which URLs they handle.

The part you cite defines a Servlet Filter. Servlet filters can do all kinds of preprocessing on requests. Your specific example is a filter had the Wicket framework uses as its entry point for all requests because filters are in some way more powerful than Servlets.

This is the deep cloning method I use, I think it Great, hope you make suggestions

function deepClone (obj) {
    var _out = new obj.constructor;

    var getType = function (n) {
        return Object.prototype.toString.call(n).slice(8, -1);
    }

    for (var _key in obj) {
        if (obj.hasOwnProperty(_key)) {
            _out[_key] = getType(obj[_key]) === 'Object' || getType(obj[_key]) === 'Array' ? deepClone(obj[_key]) : obj[_key];
        }
    }
    return _out;
}

I am so glad to solve this problem:

HttpPost httppost = new HttpPost(postData); 
CookieStore cookieStore = new BasicCookieStore(); 
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID", getSessionId());

//cookie.setDomain("your domain");
cookie.setPath("/");

cookieStore.addCookie(cookie); 
client.setCookieStore(cookieStore); 
response = client.execute(httppost); 

So Easy!

Based on @danijels's answer, dynamically create a class in VB.NET:

Imports System.Reflection
Imports System.Reflection.Emit

Public Class ObjectBuilder

Public Property myType As Object
Public Property myObject As Object

Public Sub New(fields As List(Of Field))
    myType = CompileResultType(fields)
    myObject = Activator.CreateInstance(myType)
End Sub

Public Shared Function CompileResultType(fields As List(Of Field)) As Type
    Dim tb As TypeBuilder = GetTypeBuilder()
    Dim constructor As ConstructorBuilder = tb.DefineDefaultConstructor(MethodAttributes.[Public] Or MethodAttributes.SpecialName Or MethodAttributes.RTSpecialName)

    For Each field In fields
        CreateProperty(tb, field.Name, field.Type)
    Next

    Dim objectType As Type = tb.CreateType()
    Return objectType
End Function

Private Shared Function GetTypeBuilder() As TypeBuilder
    Dim typeSignature = "MyDynamicType"
    Dim an = New AssemblyName(typeSignature)
    Dim assemblyBuilder As AssemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(an, AssemblyBuilderAccess.Run)
    Dim moduleBuilder As ModuleBuilder = assemblyBuilder.DefineDynamicModule("MainModule")
    Dim tb As TypeBuilder = moduleBuilder.DefineType(typeSignature, TypeAttributes.[Public] Or TypeAttributes.[Class] Or TypeAttributes.AutoClass Or TypeAttributes.AnsiClass Or TypeAttributes.BeforeFieldInit Or TypeAttributes.AutoLayout, Nothing)
    Return tb
End Function

Private Shared Sub CreateProperty(tb As TypeBuilder, propertyName As String, propertyType As Type)
    Dim fieldBuilder As FieldBuilder = tb.DefineField("_" & propertyName, propertyType, FieldAttributes.[Private])

    Dim propertyBuilder As PropertyBuilder = tb.DefineProperty(propertyName, PropertyAttributes.HasDefault, propertyType, Nothing)
    Dim getPropMthdBldr As MethodBuilder = tb.DefineMethod("get_" & propertyName, MethodAttributes.[Public] Or MethodAttributes.SpecialName Or MethodAttributes.HideBySig, propertyType, Type.EmptyTypes)
    Dim getIl As ILGenerator = getPropMthdBldr.GetILGenerator()

    getIl.Emit(OpCodes.Ldarg_0)
    getIl.Emit(OpCodes.Ldfld, fieldBuilder)
    getIl.Emit(OpCodes.Ret)

    Dim setPropMthdBldr As MethodBuilder = tb.DefineMethod("set_" & propertyName, MethodAttributes.[Public] Or MethodAttributes.SpecialName Or MethodAttributes.HideBySig, Nothing, {propertyType})

    Dim setIl As ILGenerator = setPropMthdBldr.GetILGenerator()
    Dim modifyProperty As Label = setIl.DefineLabel()
    Dim exitSet As Label = setIl.DefineLabel()

    setIl.MarkLabel(modifyProperty)
    setIl.Emit(OpCodes.Ldarg_0)
    setIl.Emit(OpCodes.Ldarg_1)
    setIl.Emit(OpCodes.Stfld, fieldBuilder)

    setIl.Emit(OpCodes.Nop)
    setIl.MarkLabel(exitSet)
    setIl.Emit(OpCodes.Ret)

    propertyBuilder.SetGetMethod(getPropMthdBldr)
    propertyBuilder.SetSetMethod(setPropMthdBldr)
End Sub

End Class

A simple log4j.properties file can look like this:

log4j.rootCategory=debug,console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.out
log4j.appender.console.immediateFlush=true
log4j.appender.console.encoding=UTF-8
log4j.appender.console.threshold=info

log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%d [%t] %-5p %c - %m%n

Place it in your class path (target/classes folder). Or you if you have a Maven project, place it under your src/main/resources and Eclipse will copy it to your class path.

Without a configuration file, you should see an Eclipse warning in the console like this:

log4j:WARN No appenders could be found for logger.
log4j:WARN Please initialize the log4j system properly.

You can't. If you add a member variable of type T to the class (you don't even have to initialise it), you could use that to recover the type.

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.CellType;
import org.apache.poi.hssf.usermodel.HSSFDateUtil;


Row row = sheet.getRow(0);
Cell cell = row.getCell(0);
if(cell.getCellTypeEnum() == CellType.NUMERIC||cell.getCellTypeEnum() == CellType.FORMULA)
   {
    

 String cellValue=String.valueOf(cell.getNumericCellValue());
     if(HSSFDateUtil.isCellDateFormatted(cell))
      {
          DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
          Date date = cell.getDateCellValue();
          cellValue = df.format(date);
       }
          System.out.println(cellValue);
    }

Some shortcut is to create a NumberFormatInfo class, set its NumberDecimalSeparator property to "." and use the class as parameter to ToString() method whenever u need it.

using System.Globalization;

NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = ".";

value.ToString(nfi);

If you know that the files are located in the same directory dir of the website site and have the following format: filename_01.jpg, ..., filename_10.jpg then download all of them:

import requests

for x in range(1, 10):
    str1 = 'filename_%2.2d.jpg' % (x)
    str2 = 'http://site/dir/filename_%2.2d.jpg' % (x)

    f = open(str1, 'wb')
    f.write(requests.get(str2).content)
    f.close()

Specify the column's type as type: 'date':

{title: 'Expiration Date', data: 'ExpirationDate', type: 'date'}

I've made a short code to do that and I want to share it with you.

Here the main code:

public void Send(string from, string password, string to, string Message, string subject, string host, int port, string file)
{

  MailMessage email = new MailMessage();
  email.From = new MailAddress(from);
  email.To.Add(to);
  email.Subject = subject;
  email.Body = Message;
  SmtpClient smtp = new SmtpClient(host, port);
  smtp.UseDefaultCredentials = false;
  NetworkCredential nc = new NetworkCredential(from, password);
  smtp.Credentials = nc;
  smtp.EnableSsl = true;
  email.IsBodyHtml = true;
  email.Priority = MailPriority.Normal;
  email.BodyEncoding = Encoding.UTF8;

  if (file.Length > 0)
  {
    Attachment attachment;
    attachment = new Attachment(file);
    email.Attachments.Add(attachment);
  }

  // smtp.Send(email);
  smtp.SendCompleted += new SendCompletedEventHandler(SendCompletedCallBack);
  string userstate = "sending ...";
  smtp.SendAsync(email, userstate);
}

private static void SendCompletedCallBack(object sender,AsyncCompletedEventArgs e) {
  string result = "";
  if (e.Cancelled)
  {    
    MessageBox.Show(string.Format("{0} send canceled.", e.UserState),"Message",MessageBoxButtons.OK,MessageBoxIcon.Information);
  }
  else if (e.Error != null)
  {
    MessageBox.Show(string.Format("{0} {1}", e.UserState, e.Error), "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
  }
  else {
    MessageBox.Show("your message is sended", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
  }

}

In your button do stuff like this
you can add your jpg or pdf files and more .. this is just an example

using (OpenFileDialog attachement = new OpenFileDialog()
{
  Filter = "Exel Client|*.png",
  ValidateNames = true
})
{
if (attachement.ShowDialog() == DialogResult.OK)
{
  Send("[email protected]", "gmail_password", 
       "[email protected]", "just smile ", "mail with attachement",
       "smtp.gmail.com", 587, attachement.FileName);

}
}

According to Effective Java 2nd edition (Item 13):

"If a package-private top-level class (or interface) is used by only one class, consider making the top-level class a private nested class of the sole class that uses it (Item 22). This reduces its accessibility from all the classes in its package to the one class that uses it. But it is far more important to reduce the accessibility of a gratuitously public class than a package-private top-level class: ... "

The nested class may be static or non-static based on whether the member class needs access to the enclosing instance (Item 22).

You can't "directly" mock static method (hence extension method) with mocking framework. You can try Moles (http://research.microsoft.com/en-us/projects/pex/downloads.aspx), a free tool from Microsoft that implements a different approach. Here is the description of the tool:

Moles is a lightweight framework for test stubs and detours in .NET that is based on delegates.

Moles may be used to detour any .NET method, including non-virtual/static methods in sealed types.

You can use Moles with any testing framework (it's independent about that).

You can do it on a per file basis. Use the path attribute to include the filename

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <location path="YourFileNameHere.xml">
        <system.webServer>
            <staticContent>
                <clientCache cacheControlMode="DisableCache" />
            </staticContent>
        </system.webServer>
    </location>
</configuration>

You can also check by following method.

Go to Run : type the path of DLL for which you need public key. You will find 2 files : 1. __AssemblyInfo_.ini 2. DLL file

Open this __AssemblyInfo_.ini file in notepad , here you can see Public Key Token.

You need the following jar files in the classpath:

1. antlr-2.7.6.jar
2. commons-collections-3.1.jar
3. dom4j-1.6.1.jar
4. hibernate-commons-annotations-4.0.1.Final.jar
5. hibernate-core-4.0.1.Final.jar
6. hibernate-entitymanager.jar
7. hibernate-jpa-2.0-api-1.0.0.Final.jar
8. javassist-3.9.0.jar
9. jboss-logging-3.1.1.GA.jar
10. jta-1.1.jar
11. slf4j-api-1.5.8.jar
12. xxx-jdbc-driver.jar

The LogManager class determines which log4j config to use in a static block which runs when the class is loaded. There are three options intended for end-users:

1. If you specify log4j.defaultInitOverride to false, it will not configure log4j at all.

2. Specify the path to the configuration file manually yourself and override the classpath search. You can specify the location of the configuration file directly by using the following argument to java:

   -Dlog4j.configuration=<path to properties file>

   in your test runner configuration.

3. Allow log4j to scan the classpath for a log4j config file during your test. (the default)

JaredPar's code works but only for one level of inheritance. For unlimited levels of inheritance, use the following code

public bool IsTypeDerivedFromGenericType(Type typeToCheck, Type genericType)

    if (typeToCheck == typeof(object))
    {
        return false;
    }
    else if (typeToCheck == null)

http://guess.scritch.org/ does this for CMSs.

Just pop in the URL and it'll try to guess the CMS. In this case it tells me my blog is running wordpress 3.4.2 (which is correct, I just checked!)

I am a git newbie as well. I had the same problem with 'your branch is ahead of origin/master by N commits' messages. Doing the suggested 'git diff origin/master' did show some diffs that I did not care to keep. So ...

Since my git clone was for hosting, and I wanted an exact copy of the master repo, and did not care to keep any local changes, I decided to save off my entire repo, and create a new one:

(on the hosting machine)

mv myrepo myrepo
git clone USER@MASTER_HOST:/REPO_DIR myrepo

For expediency, I used to make changes to the clone on my hosting machine. No more. I will make those changes to the master, git commit there, and do a git pull. Hopefully, this should keep my git clone on the hosting machine in complete sync.

This is because there is another process in the network sending RST to your TCP connection.

Normally RST would be sent in the following case

• A process close the socket when socket using SO_LINGER option is enabled
• OS is doing the resource cleanup when your process exit without closing socket.

In your case, it sounds like a process is connecting your connection(IP + port) and keeps sending RST after establish the connection.

It's been awhile since I used a GridView, but I think you need to set the grid's SortDirection property to whatever it currently is before leaving the OnSorting method.

So....

List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection();
items.Sort(new Helpers.GenericComparer<V_ReportPeriodStatusEntity>(e.SortExpression, e.SortDirection));
grdHeader.SortDirection = e.SortDirection.Equals(SortDirection.Ascending) ? SortDirection.Descending : SortDirection.Ascending;
grdHeader.DataSource = items;
grdHeader.DataBind();

Here is the code for it, enjoy!, I picked that up from the dotNetReference type the "using" statement inside the namespace line 106 http://referencesource.microsoft.com/#mscorlib/microsoft/win32/win32native.cs

using System;
using System.Collections.Generic;
namespace UsingStatement
{
    using Typedeffed = System.Int32;
    using TypeDeffed2 = List<string>;
    class Program
    {
        static void Main(string[] args)
        {
        Typedeffed numericVal = 5;
        Console.WriteLine(numericVal++);

        TypeDeffed2 things = new TypeDeffed2 { "whatever"};
        }
    }
}

Perl Core Language - Little Black Book - excellent reference!

Change the body element into a flex container and the div into a flex item:

body {_x000D_
  display: flex;_x000D_
  height: 100vh;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
div {_x000D_
  flex: 1;_x000D_
  background: tan;_x000D_
}

<div></div>

Should be something along these lines:

function setValue(inVal){
var dl = document.getElementById('leaveCode');
var el =0;
for (var i=0; i<dl.options.length; i++){
  if (dl.options[i].value == inVal){
    el=i;
    break;
  }
}
dl.selectedIndex = el;
}

you can use pass inside if statement.

Consider the graph shown below with the source as Vertex A. First try running Dijkstra’s algorithm yourself on it.

When I refer to Dijkstra’s algorithm in my explanation I will be talking about the Dijkstra's Algorithm as implemented below,

So starting out the values (the distance from the source to the vertex) initially assigned to each vertex are,

We first extract the vertex in Q = [A,B,C] which has smallest value, i.e. A, after which Q = [B, C]. Note A has a directed edge to B and C, also both of them are in Q, therefore we update both of those values,

Now we extract C as (2<5), now Q = [B]. Note that C is connected to nothing, so line16 loop doesn't run.

Finally we extract B, after which . Note B has a directed edge to C but C isn't present in Q therefore we again don't enter the for loop in line16,

So we end up with the distances as

Note how this is wrong as the shortest distance from A to C is 5 + -10 = -5, when you go .

So for this graph Dijkstra's Algorithm wrongly computes the distance from A to C.

This happens because Dijkstra's Algorithm does not try to find a shorter path to vertices which are already extracted from Q.

What the line16 loop is doing is taking the vertex u and saying "hey looks like we can go to v from source via u, is that (alt or alternative) distance any better than the current dist[v] we got? If so lets update dist[v]"

Note that in line16 they check all neighbors v (i.e. a directed edge exists from u to v), of u which are still in Q. In line14 they remove visited notes from Q. So if x is a visited neighbour of u, the path is not even considered as a possible shorter way from source to v.

In our example above, C was a visited neighbour of B, thus the path was not considered, leaving the current shortest path unchanged.

This is actually useful if the edge weights are all positive numbers, because then we wouldn't waste our time considering paths that can't be shorter.

So I say that when running this algorithm if x is extracted from Q before y, then its not possible to find a path - which is shorter. Let me explain this with an example,

As y has just been extracted and x had been extracted before itself, then dist[y] > dist[x] because otherwise y would have been extracted before x. (line 13 min distance first)

And as we already assumed that the edge weights are positive, i.e. length(x,y)>0. So the alternative distance (alt) via y is always sure to be greater, i.e. dist[y] + length(x,y)> dist[x]. So the value of dist[x] would not have been updated even if y was considered as a path to x, thus we conclude that it makes sense to only consider neighbors of y which are still in Q (note comment in line16)

But this thing hinges on our assumption of positive edge length, if length(u,v)<0 then depending on how negative that edge is we might replace the dist[x] after the comparison in line18.

So any dist[x] calculation we make will be incorrect if x is removed before all vertices v - such that x is a neighbour of v with negative edge connecting them - is removed.

Because each of those v vertices is the second last vertex on a potential "better" path from source to x, which is discarded by Dijkstra’s algorithm.

So in the example I gave above, the mistake was because C was removed before B was removed. While that C was a neighbour of B with a negative edge!

Just to clarify, B and C are A's neighbours. B has a single neighbour C and C has no neighbours. length(a,b) is the edge length between the vertices a and b.

To check what version you currently have, you can use -v for the command line/console terminal.

Cache

Clear your cache. http://support.google.com/chrome/bin/answer.py?hl=en&answer=95582 And test another browser.

Some where able to get an updated favicon by adding an URL parameter: ?v=1 after the link href which changes the resource link and therefore loads the favicon without cache (thanks @Stanislav).

<link rel="icon" type="image/x-icon" href="favicon.ico?v=2"  />

Favicon Usage

How did you import the favicon? How you should add it.

Normal favicon:

<link rel="icon" href="favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon" />

PNG/GIF favicon:

<link rel="icon" type="image/gif" href="favicon.gif" />
<link rel="icon" type="image/png" href="favicon.png" />

in the <head> Tag.

Chrome local problem

Another thing could be the problem that chrome can't display favicons, if it's local (not uploaded to a webserver). Only if the file/icon would be in the downloads directory chrome is allowed to load this data - more information about this can be found here: local (file://) website favicon works in Firefox, not in Chrome or Safari- why?

Renaming

Try to rename it from favicon.{whatever} to {yourfaviconname}.{whatever} but I would suggest you to still have the normal favicon. This has solved my issue on IE.

Base64 approach

Found another solution for this which works great! I simply added my favicon as Base64 Encoded Image directly inside the tag like this:

Generate favicons

I can really suggest you this page: http://www.favicon-generator.org/ to create all types of favicons you need.

The problem is that --exclude="*" says to exclude (for example) the 1260000000/ directory, so rsync never examines the contents of that directory, so never notices that the directory contains files that would have been matched by your --include.

I think the closest thing to what you want is this:

rsync -nrv --include="*/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/

(which will include all directories, and all files matching file_11*.jpg, but no other files), or maybe this:

rsync -nrv --include="/[0-9][0-9][0-9]0000000/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/

(same concept, but much pickier about the directories it will include).

This solution works for me:

First, put a resources folder under webapp/WEB-INF, as follow structure

-- src
  -- main
    -- webapp
      -- WEB-INF
        -- resources
          -- css
          -- image
          -- js
          -- ...

Second, in spring config file

@Configuration
@EnableWebMvc
public class MvcConfig extends WebMvcConfigurerAdapter{

    @Bean
    public ViewResolver getViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".html");
        return resolver;
    }

    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resource/**").addResourceLocations("WEB-INF/resources/");
    }
}

Then, you can access your resource content, such as http://localhost:8080/resource/image/yourimage.jpg

For text:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

For cell background

[RangeObject].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

I wanted something pretty close to this - the moment a user picks an item, even by just hitting the arrow keys to one (focus), I want that data item attached to the tag in question. When they type again without picking another item, I want that data cleared.

(function() {
    var lastText = '';

    $('#MyTextBox'), {
        source: MyData
    })
    .on('autocompleteselect autocompletefocus', function(ev, ui) {
        lastText = ui.item.label;
        jqTag.data('autocomplete-item', ui.item);
    })
    .keyup(function(ev) {
        if (lastText != jqTag.val()) {
            // Clear when they stop typing
            jqTag.data('autocomplete-item', null);

            // Pass the event on as autocompleteclear so callers can listen for select/clear
            var clearEv = $.extend({}, ev, { type: 'autocompleteclear' });
            return jqTag.trigger(clearEv);
    });
})();

With this in place, 'autocompleteselect' and 'autocompletefocus' still fire right when you expect, but the full data item that was selected is always available right on the tag as a result. 'autocompleteclear' now fires when that selection is cleared, generally by typing something else.

This is the easiest way to do this...

sql = "select username from usermst where userid=2"
object getusername = command.ExecuteScalar();
if (getusername!=null)
{
    //do whatever with the value here
    //use getusername.toString() to get the value from the query
}

In Typescript use the For Each like below.

selectChildren(data, $event) {
let parentChecked = data.checked;
for(var obj in this.hierarchicalData)
    {
        for (var childObj in obj )
        {
            value.checked = parentChecked;
        }
    }
}

Pure/vanilla JS solution (working example here)

// All elements with data-company="Microsoft" below "Companies"
let a = document.querySelectorAll("[data-group='Companies'] [data-company='Microsoft']"); 

// All elements with data-company!="Microsoft" below "Companies"
let b = document.querySelectorAll("[data-group='Companies'] :not([data-company='Microsoft'])"); 

In querySelectorAll you must use valid CSS selector (currently Level3)

SPEED TEST (2018.06.29) for jQuery and Pure JS: test was performed on MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit). Below screenshot shows results for fastest browser (Safari):

PureJS was faster than jQuery about 12% on Chrome, 21% on Firefox and 25% on Safari. Interestingly speed for Chrome was 18.9M operation per second, Firefox 26M, Safari 160.9M (!).

So winner is PureJS and fastest browser is Safari (more than 8x faster than Chrome!)

You can do a side-by-side diff using sdiff as follows:

$ git difftool -y -x sdiff  HEAD^ | less

where HEAD^ is an example that you should replace with whatever you want to diff against.

I found this solution here where there are a couple of other suggestions also. However, this one answer's the OP's question succinctly and clearly.

See the man git-difftool for an explanation of the arguments.

Taking the comments on board, you can create a handy git sdiff command by writing the following executable script:

#!/bin/sh
git difftool -y -x "sdiff -w $(tput cols)" "${@}" | less

Save it as /usr/bin/git-sdiff and chmod +x it. Then you'll be able to do this:

$ git sdiff HEAD^

Extra Tip

As suggested in comments you can use icdiff to do what sdiff does with colored output:

$ more /usr/bin/git-sdiff
#!/bin/sh
git difftool -y -x "icdiff --cols=$(tput cols)" "${@}" | less

You can use this script. http://pellepim.bitbucket.org/jstz/

Fork or clone repository here. https://bitbucket.org/pellepim/jstimezonedetect

Once you include the script, you can get the list of timezones in - jstz.olson.timezones variable.

And following code is used to determine client browser's timezone.

var tz = jstz.determine();
tz.name();

Enjoy jstz!

Firstly make sure that you have installed python 2.7 or higher

Open Command Prompt as administrator and change directory to python and then change directory to Scripts by typing cd Scripts then type pip.exe and now you can install modules Step by Step:

• Open Cmd

• type in "cd \" and then enter

• type in "cd python2.7" and then enter

Note that my python version is 2.7 so my directory is that so use your python folder here...

• type in "cd Scripts" and enter

• Now enter this "pip.exe"

• Now it prompts you to install modules

The actual problem is with your

showList function.

There is an extra ')' after 'visible'.

Remove that and it will work fine.

function showList()
{
  if (document.getElementById("favSports").style.visibility == "hidden") 
    {
       // document.getElementById("favSports").style.visibility = "visible");  
       // your code
       document.getElementById("favSports").style.visibility = "visible";
       // corrected code
    }
}

Fastest way I found is via inner1d. Here's how it compares to other numpy methods:

import numpy as np
from numpy.core.umath_tests import inner1d

V = np.random.random_sample((10**6,3,)) # 1 million vectors
A = np.sqrt(np.einsum('...i,...i', V, V))
B = np.linalg.norm(V,axis=1)   
C = np.sqrt((V ** 2).sum(-1))
D = np.sqrt((V*V).sum(axis=1))
E = np.sqrt(inner1d(V,V))

print [np.allclose(E,x) for x in [A,B,C,D]] # [True, True, True, True]

import cProfile
cProfile.run("np.sqrt(np.einsum('...i,...i', V, V))") # 3 function calls in 0.013 seconds
cProfile.run('np.linalg.norm(V,axis=1)')              # 9 function calls in 0.029 seconds
cProfile.run('np.sqrt((V ** 2).sum(-1))')             # 5 function calls in 0.028 seconds
cProfile.run('np.sqrt((V*V).sum(axis=1))')            # 5 function calls in 0.027 seconds
cProfile.run('np.sqrt(inner1d(V,V))')                 # 2 function calls in 0.009 seconds

inner1d is ~3x faster than linalg.norm and a hair faster than einsum

What does res.render do and what does the html file look like?

res.render() function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.

Answering Edit 2 part.

// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');

// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');

// here you render `orders` template
response.render("orders", {orders: orders_json});

So, the template path is views/ (first part) + orders (second part) + .ejs (third part) === views/orders.ejs

Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.

No plugin required. You can use only jquery.

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

You can't truly do it in "standard" C, because the size of an int and of a char aren't fixed. Let's say you are using a compiler under Windows or Linux on an intel PC...

int i = 5;
char a = ((char*)&i)[0];
char b = ((char*)&i)[1];

Remember of endianness of your machine! And that int are "normally" 32 bits, so 4 chars!

But you probably meant "i want to stringify a number", so ignore this response :-)

I just spent about 1 hour to figure out possible solution for the same error.

So what I did under MS WIndows 7 is following

1. Uninstall all Java packages of all versions.

2. Download last packages Java SE or JRE for your 32 or 64 Windows and install it.

3. First install JRE and second is Java SE.

4. Open text editor and paste this code.

   public class Hello {

     public static void main(String[] args) {
   
        System.out.println("test");
   
     }
   
   } 
   

5. Save it like Hello.java

6. Go to Console and compile it like

javac Hello.java

7. Execute the code like

java Hello

Should be no error.

There are a couple alternatives for installing as a service virtually any Windows executable.

Method 1: Use instsrv and srvany from rktools.exe

For Windows Home Server or Windows Server 2003 (works with WinXP too), the Windows Server 2003 Resource Kit Tools comes with utilities that can be used in tandem for this, called instsrv.exe and srvany.exe. See this Microsoft KB article KB137890 for details on how to use these utils.

For Windows Home Server, there is a great user friendly wrapper for these utilities named aptly "Any Service Installer".

Method 2: Use ServiceInstaller for Windows NT

There is another alternative using ServiceInstaller for Windows NT (download-able here) with python instructions available. Contrary to the name, it works with both Windows 2000 and Windows XP as well. Here are some instructions for how to install a python script as a service.

Installing a Python script

Run ServiceInstaller to create a new service. (In this example, it is assumed that python is installed at c:\python25)

Service Name  : PythonTest
Display Name : PythonTest 
Startup : Manual (or whatever you like)
Dependencies : (Leave blank or fill to fit your needs)
Executable : c:\python25\python.exe
Arguments : c:\path_to_your_python_script\test.py
Working Directory : c:\path_to_your_python_script

After installing, open the Control Panel's Services applet, select and start the PythonTest service.

After my initial answer, I noticed there were closely related Q&A already posted on SO. See also:

Can I run a Python script as a service (in Windows)? How?

How do I make Windows aware of a service I have written in Python?

There was some discussion of this on security.stackexchange.com recently

functions that can be used for arbitrary code execution

Well that reduces the scope a little - but since 'print' can be used to inject javascript (and therefore steal sessions etc) its still somewhat arbitrary.

isn't to list functions that should be blacklisted or otherwise disallowed. Rather, I'd like to have a grep-able list

That's a sensible approach.

Do consider writing your own parser though - very soon you're going to find a grep based approach getting out of control (awk would be a bit better). Pretty soon you're also going to start wishing you'd implemented a whitelist too!

In addition to the obvious ones, I'd recommend flagging up anything which does an include with an argument of anything other than a string literal. Watch out for __autoload() too.

Try

L.replaceAll("(\\t|\\r?\\n)+", " ");

Depending on the system a linefeed is either \r\n or just \n.

i think this is the better query for stamp_created and stamp_updated

CREATE TABLE test_table( 
    id integer not null auto_increment primary key, 
    stamp_created TIMESTAMP DEFAULT now(), 
    stamp_updated TIMESTAMP DEFAULT '0000-00-00 00:00:00' ON UPDATE now() 
); 

because when the record created, stamp_created should be filled by now() and stamp_updated should be filled by '0000-00-00 00:00:00'

I think we could write in the following way to retrieve(below code is just an example, please modify as needed):

Create FUNCTION dbo.ufnGetEmployeeMultiple(@DepartmentID int)
RETURNS VARCHAR(1000) AS

BEGIN

DECLARE @Employeelist varchar(1000)

SELECT @Employeelist = COALESCE(@Employeelist + ', ', '') + E.LoginID
FROM humanresources.Employee E

Left JOIN humanresources.EmployeeDepartmentHistory H ON
E.BusinessEntityID = H.BusinessEntityID

INNER JOIN HumanResources.Department D ON
H.DepartmentID = D.DepartmentID

Where H.DepartmentID = @DepartmentID

Return @Employeelist

END

SELECT D.name as Department, dbo.ufnGetEmployeeMultiple (D.DepartmentID)as Employees
FROM HumanResources.Department D

SELECT Distinct (D.name) as Department, dbo.ufnGetEmployeeMultiple (D.DepartmentID) as 
Employees
FROM HumanResources.Department D

cout is in std namespace, you shall use std::cout in your code. And you shall not add using namespace std; in your header file, it's bad to mix your code with std namespace, especially don't add it in header file.

You could use the [DataType] attribute on your view model like this:

public class MyViewModel
{
    [DataType(DataType.MultilineText)]
    public string Text { get; set; }
}

and then you could have a controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }
}

and a view which does what you want:

@model AppName.Models.MyViewModel
@using (Html.BeginForm())
{
    @Html.EditorFor(x => x.Text)
    <input type="submit" value="OK" />
}

Practice, practice, practice.

You can read about playing the cello for years, and still not be able to put a bow to instrument and make anything that sounds like music.

Design patterns are best recognized as a high-level issue; one that is only relevant if you have the experience necessary to recognize them as useful. It's good that you recognize that they're useful, but unless you've seen situations where they would apply, or have applied, it's almost impossible to understand their true value.

Where they become useful is when you recognize design patterns in others' code, or recognize a problem in the design phase that fits well with a pattern; and then examine the formal pattern, and examine the problem, and determine what the delta is between them, and what that says about both the pattern and the problem.

It's really the same as coding; K&R may be the "bible" for C, but reading it cover-to-cover several times just doesn't give one practical experience; there's no replacement for experience.

This error may be due to less field size than your entered data.

For e.g. if you have data type nvarchar(7) and if your value is 'aaaaddddf' then error is shown as:

string or binary data would be truncated

That's not possible using the built-in Array.prototype.map. However, you could use a simple for-loop instead, if you do not intend to map any values:

var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
  if (myArray[i] < 10) {
    hasValueLessThanTen = true;
    break;
  }
}

Or, as suggested by @RobW, use Array.prototype.some to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:

var hasValueLessThanTen = myArray.some(function (val) { 
  return val < 10;
});

For Angular 2+ to get the offset of the current element (this.el.nativeElement is equvalent of $(this) in jquery):

export class MyComponent implements  OnInit {

constructor(private el: ElementRef) {}

    ngOnInit() {
      //This is the important line you can use in your function in the code
      //-------------------------------------------------------------------------- 
        let offset = this.el.nativeElement.getBoundingClientRect().top;
      //--------------------------------------------------------------------------    

        console.log(offset);
    }

}

    var l = document.getElementsByClassName("chatMessages").length;
    document.getElementsByClassName("chatMessages")[l-1].scrollIntoView();

this should work

Have you tried following the advice on the linked help page? The help page at http://g.co/mapsJSApiErrors says:

ApiNotActivatedMapError

The Google Maps JavaScript API is not activated on your API project. You may need to enable the Google Maps JavaScript API under APIs in the Google Developers Console.

See Obtaining an API key.

So check that the key you are using has Google Maps JavaScript API enabled.

You can compare different methods very well explained on this page: http://blog.themeforest.net/tutorials/vertical-centering-with-css/

The method they recommend is adding a empty floating element before the content you cant centered, and clearing it. It doesn't have the downside you mentioned.

I forked your JSBin to apply it : http://jsbin.com/iquviq/7/edit

HTML

<div id="floater">
</div>

<div id="content">
  Content here
</div>

CSS

#floater {
  float: left; 
  height: 50%; 
  margin-bottom: -300px;
}

#content {
  clear: both; 
  width: 200px;
  height: 600px;
  position: relative; 
  margin: auto;
}

Simply add this to your css :-

.navbar-inner {
    background:transparent;
}

Coming from someone who has tried a number of "C# IDEs" on the Mac, your best bet is to install a virtual desktop with Windows and Visual Studio. It really is the best development IDE out there for .NET, nothing even comes close.

On a related note: I hate XCode.

Update: Use Xamarin Studio. It's solid.

Python has a built-in function called sorted, which will give you a sorted list from any iterable you feed it (such as a list ([1,2,3]); a dict ({1:2,3:4}, although it will just return a sorted list of the keys; a set ({1,2,3,4); or a tuple ((1,2,3,4))).

>>> x = [3,2,1]
>>> sorted(x)
[1, 2, 3]
>>> x
[3, 2, 1]

Lists also have a sort method that will perform the sort in-place (x.sort() returns None but changes the x object) .

>>> x = [3,2,1]
>>> x.sort()
>>> x
[1, 2, 3]

Both also take a key argument, which should be a callable (function/lambda) you can use to change what to sort by.
For example, to get a list of (key,value)-pairs from a dict which is sorted by value you can use the following code:

>>> x = {3:2,2:1,1:5}
>>> sorted(x.items(), key=lambda kv: kv[1])  # Items returns a list of `(key,value)`-pairs
[(2, 1), (3, 2), (1, 5)]

Use either a simple blank * or [:blank:]* to remove all possible spaces at the end of the line:

sed 's/ *$//' file

Using the [:blank:] class you are removing spaces and tabs:

sed 's/[[:blank:]]*$//' file

Note this is POSIX, hence compatible in both GNU sed and BSD.

For just GNU sed you can use the GNU extension \s* to match spaces and tabs, as described in BaBL86's answer. See POSIX specifications on Basic Regular Expressions.

Let's test it with a simple file consisting on just lines, two with just spaces and the last one also with tabs:

$ cat -vet file
hello   $
bye   $
ha^I  $     # there is a tab here

Remove just spaces:

$ sed 's/ *$//' file | cat -vet -
hello$
bye$
ha^I$       # tab is still here!

Remove spaces and tabs:

$ sed 's/[[:blank:]]*$//' file | cat -vet -
hello$
bye$
ha$         # tab was removed!

No, as of Notepad++ 5.6.2, this doesn't seem to be possible. Although column selection (Alt+Selection) is possible, multiple selections are obviously not implemented and thus also not supported by the search function.

This one also work!!

$elem.attr('style','');

Something like this:

.base {
    width:100px;
}

div.child {
    background-color:red;
    color:blue;
}

.child {
    background-color:yellow;
}

<div class="base child">
    hello world
</div>

The background here will be red, as the css selector is more specific, as we've said it must belong to a div element too!

see it in action here: jsFiddle

ES6 React.Component doesn't auto bind methods to itself. You need to bind them yourself in constructor. Like this:

constructor (props){
  super(props);
  
  this.state = {
      loopActive: false,
      shuffleActive: false,
    };
  
  this.onToggleLoop = this.onToggleLoop.bind(this);

}

This has been asked many times. A possible solution can be found here: https://stackoverflow.com/a/6527838/552671

This solution requires both an UPDATE and INSERT.

UPDATE table SET field='C', field2='Z' WHERE id=3;
INSERT INTO table (id, field, field2)
       SELECT 3, 'C', 'Z'
       WHERE NOT EXISTS (SELECT 1 FROM table WHERE id=3);

With Postgres 9.1 it is possible to do it with one query: https://stackoverflow.com/a/1109198/2873507

Map:

Map transformation.

The map works on a single Row at a time.

Map returns after each input Row.

The map doesn’t hold the output result in Memory.

Map no way to figure out then to end the service.

// map example

val dfList = (1 to 100) toList

val df = dfList.toDF()

val dfInt = df.map(x => x.getInt(0)+2)

display(dfInt)

MapPartition:

MapPartition transformation.

MapPartition works on a partition at a time.

MapPartition returns after processing all the rows in the partition.

MapPartition output is retained in memory, as it can return after processing all the rows in a particular partition.

MapPartition service can be shut down before returning.

// MapPartition example

Val dfList = (1 to 100) toList

Val df = dfList.toDF()

Val df1 = df.repartition(4).rdd.mapPartition((int) => Iterator(itr.length))

Df1.collec()

//display(df1.collect())

For more details, please refer to the Spark map vs mapPartitions transformation article.

Hope this is helpful!

sizeof str is 7 - five bytes for the "Hello" text, plus the explicit NUL terminator, plus the implicit NUL terminator.

strlen(str) is 5 - the five "Hello" bytes only.

The key here is that the implicit nul terminator is always added - even if the string literal just happens to end with \0. Of course, strlen just stops at the first \0 - it can't tell the difference.

There is one exception to the implicit NUL terminator rule - if you explicitly specify the array size, the string will be truncated to fit:

char str[6] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 6 (with one NUL)
char str[7] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 7 (with two NULs)
char str[8] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 8 (with three NULs per C99 6.7.8.21)

This is, however, rarely useful, and prone to miscalculating the string length and ending up with an unterminated string. It is also forbidden in C++.

In SQL Server 2012, 2014:

USE mydb
GO

ALTER ROLE db_datareader ADD MEMBER MYUSER
GO
ALTER ROLE db_datawriter ADD MEMBER MYUSER

In SQL Server 2008:

use mydb
go

exec sp_addrolemember db_datareader, MYUSER 
go
exec sp_addrolemember db_datawriter, MYUSER

To also assign the ability to execute all Stored Procedures for a Database:

GRANT EXECUTE TO MYUSER;

To assign the ability to execute specific stored procedures:

GRANT EXECUTE ON dbo.sp_mystoredprocedure TO MYUSER;

Yes, just create a directory in your solution like lib/, and then add your dll to that directory in the filesystem and add it in the project (Add->Existing Item->etc). Then add the reference based on your project.

I have done this several times under svn and under cvs.

I'm too late to the party but thought this might help someone.

Here's an abstraction of Will Nathan's answer if anyone just wants an easy copy-paste add-in function:

function find (name, query, cb) {
    mongoose.connection.db.collection(name, function (err, collection) {
       collection.find(query).toArray(cb);
   });
}

simply do find(collection_name, query, callback); to be given the result.

for example, if I have a document { a : 1 } in a collection 'foo' and I want to list its properties, I do this:

find('foo', {a : 1}, function (err, docs) {
            console.dir(docs);
        });
//output: [ { _id: 4e22118fb83406f66a159da5, a: 1 } ]

I tried this and it worked

<div style=" position: absolute; direction: ltr;height:auto; min-height:100%">   </div>

Get rid of the this statements too

var img = document.createElement("img");
img.src = "img/eqp/"+this.apparel+"/"+this.facing+"_idle.png";
src = document.getElementById("gamediv");
src.appendChild(this.img)

remove float: left from image css and add text-align: center property in parent element body

For ios6 using autolayout I had to add a little bit of code to remove the constraints too.

NSMutableArray * constraints_to_remove = [ @[] mutableCopy] ;
for( NSLayoutConstraint * constraint in tagview.constraints) {
    if( [tagview.subviews containsObject:constraint.firstItem] ||
       [tagview.subviews containsObject:constraint.secondItem] ) {
        [constraints_to_remove addObject:constraint];
    }
}
[tagview removeConstraints:constraints_to_remove];

[ [tagview subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];

I'm sure theres a neater way to do this, but it worked for me. In my case I could not use a direct [tagview removeConstraints:tagview.constraints] as there were constraints set in XCode that were getting cleared.

if your list has negative numbers, this is how you would normalize it

a = range(-30,31,5)
norm = [(float(i)-min(a))/(max(a)-min(a)) for i in a]

The last part of the error message you quoted states: ...with ("checkPermission") or explicitly handle a potential "SecurityException"

A much quicker/simpler way of checking if you have permissions is to surround your code with try { ... } catch (SecurityException e) { [insert error handling code here] }. If you have permissions, the 'try' part will execute, if you don't, the 'catch' part will.

This is a simple fix. Your mysql database has lost its connection to the server. If you are running a local server run this in your terminal:

mysqld

That will reconnect your database. Then (if you are using homebrew) run:

brew services start mysql

This will automatically connect your database on login.

Most Subversion commands take the --username option to specify the username you want to use to the repository. Subversion remembers the last repository username and password used in each working copy, which means, among other things, that if you use svn checkout --username myuser you never need to specify the username again.

As Kamil Kisiel says, when Subversion is accessing the repository directly off the file system (that is, the repository URL is of form file:///path/to/repo or file://file-server/path/to/repo), it uses your file system permissions to access the repository. And when you connect via SSH tunneling (svn+ssh://server/path/to/repo), SVN uses your FS permissions on the server, as determined by your SSH login. In those cases, svn checkout --username may not work for your repository.

I also encountered this issue on RHEL machine. I did not find any apt solution anywhere on stack-overflow and docker-hub community. If you are facing this issue even after below command:

docker system prune --all

The solution which worked finally:

1. docker info
   • To check current docker storage driver
   • Mine was : Storage Driver: devicemapper; If you have storage driver as overlay2 nothing to worry about. Solution will still work for you.
2. df -h
   • This is to check the available file systems on machine and the path where they are mounted. Two mounted path to have a note:
   • /dev/mapper/rootvg-var 7.6G 1.2G 6.1G 16% /var
   • /dev/mapper/rootvg-apps 60G 9.2G 48G 17% /apps
   • Note- By default docker storage path is /var/lib/docker. It has available space ~6 GB and hence all the space related issues. So basically, I have to move default storage to some other storage where available space is more. For me its File sysyem path '/dev/mapper/rootvg-apps' which is mounted on /apps. Now task is to move /var/lib/docker to something like /apps/newdocker/docker.
3. mkdir /apps/newdocker/docker
4. chmod -R 777 /apps/newdocker/docker
5. Update docker.serive file on linux which resides under: /usr/lib/systemd/system
   • vi /usr/lib/systemd/system/docker.service
6. if storage device is devicemapper , comment existing ExecStart line and add below under [Service]:
   • ExecStart=
   • ExecStart=/usr/bin/dockerd -s devicemapper --storage-opt dm.fs=xfs --storage-opt dm.basesize=40GB -g /apps/newdocker/docker --exec-opt native.cgroupdriver=cgroupfs
7. Or if storage device is overlay2:
   • just add -g /apps/newdocker/docker in the existing ExexStart statement.
   • Something like ExecStart=/usr/bin/dockerd -g /apps/newdocker/docker -H fd:// --containerd=/run/containerd/containerd.sock
8. rm -rf /var/lib/docker (It will delete all existing docker data)
9. systemctl stop docker
10. ps aux | grep -i docker | grep -v grep
    • If no output has been produced by the above command, reload systemd daemon by below command.
11. systemctl daemon-reload
12. systemctl start docker
13. docker info
    • Check out the Data Space Available: 62.15GB after mouting to docker to new File system.
14. DONE

For specific month and year use date() as natural language as following

$first_date = date('d-m-Y',strtotime('first day of april 2010'));
$last_date = date('d-m-Y',strtotime('last day of april 2010'));
// Isn't it simple way?

but for Current month

$first_date = date('d-m-Y',strtotime('first day of this month'));
$last_date = date('d-m-Y',strtotime('last day of this month'));

You can add 'debugger' in your code and reload the app, which puts the breakpoint there and you can 'step over' , or run.

var service = {
user_id: null,
getCurrentUser: function() {
  debugger; // Set the debugger inside 
            // this function
  return service.user_id;
}

Rails 4 no longer generates the non fingerprinted version of the asset: stylesheets/style.css will not be generated for you.

If you use stylesheet_link_tag then the correct link to your stylesheet will be generated

In addition styles.css should be in config.assets.precompile which is the list of things that are precompiled

I think gmail just tracks the scroll position on a timer and repositions a div accordingly.

The best solution I've seen is at doctyper.

A simpler jQuery solution that moves an element onscroll: link

You can use ToList to convert to a list. For example,

SomeItems.ToList()[1]

The easy option is to use group by and select min/max for all other fields

SELECT TOP 10 
    p.id, 
    max(pl.nm),
    max(pl.val),
    max(pl.txt_val)
from 
    dm.labs pl
join 
    mas_data.patients p    
on 
    pl.id = p.id
  where 
    pl.nm like '%LDL%'
and 
    val is not null
group by 
    p.id

This can get quite tedious for wide table so the other option is to use rank over and partiion

SELECT TOP 10 
    p.id, 
     pl.nm, 
     pl.val, 
   pl.txt_val, 
    rank() over(partition by p.id order by p.id) as Rank
from 
    dm.labs pl
join 
    mas_data.patients p    
on 
    pl.id = p.id
  where 
    pl.nm like '%LDL%'
and 
    val is not null
and
    Rank = 1

You don't need the jsp:useBean to set the model if you already have a controller which prepared the model.

Just access it plain by EL:

<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>

or by JSTL <c:out> tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:

<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>

See also:

• Our Servlets wiki page

Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.

session.setAttribute("questions", questions);

and alter EL accordingly to use ${questions}.

Also note that you don't have any JSTL tag in your code. It's all plain JSP.

@Html.ActionLink("Edit","ActionName",new{id=item.id},new{onclick="functionname();"})

You can try following sample http://jsfiddle.net/xKJB8/3/

<img id="preview" src="http://www.gravatar.com/avatar/0e39d18b89822d1d9871e0d1bc839d06?s=128&d=identicon&r=PG">
<canvas id="myCanvas" />

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
var img = document.getElementById("preview");
ctx.drawImage(img, 10, 10);
alert(c.toDataURL());

You can do this: If your tomcat installation is default and you have not done any changes, then the default war will be ROOT.war. Thus whenever you will call http://yourserver.example.com/, it will call the index.html or index.jsp of your default WAR file. Make the following changes in your webapp/ROOT folder for redirecting requests to http://yourserver.example.com/somewhere/else:

1. Open webapp/ROOT/WEB-INF/web.xml, remove any servlet mapping with path /index.html or /index.jsp, and save.

2. Remove webapp/ROOT/index.html, if it exists.

3. Create the file webapp/ROOT/index.jsp with this line of content:

   <% response.sendRedirect("/some/where"); %>
   

   or if you want to direct to a different server,

   <% response.sendRedirect("http://otherserver.example.com/some/where"); %>
   

That's it.

An easier solution is to use the user:pass@host format directly in the URL.

Using the request library:

var request = require('request'),
    username = "john",
    password = "1234",
    url = "http://" + username + ":" + password + "@www.example.com";

request(
    {
        url : url
    },
    function (error, response, body) {
        // Do more stuff with 'body' here
    }
);

I've written a little blogpost about this as well.

Method 1:

from django.shortcuts import render_to_response
return render_to_response(
    'history.html',
    RequestContext(request, {
        'account_form': form,
    })

Method 2 :

from django.shortcuts import render
return render(request, 'history.html', {
    'account_form': form,
})

Because render_to_response method may case some problem of response cookies.

A GUID is a 128 bit integer (its just in hex rather than base 10). With .NET 4 use http://msdn.microsoft.com/en-us/library/dd268285%28v=VS.100%29.aspx like so:

// Turn a GUID into a string and strip out the '-' characters.
BigInteger huge = BigInteger.Parse(modifiedGuidString, NumberStyles.AllowHexSpecifier)

If you don't have .NET 4 you can look at IntX or Solver Foundation.

This example work.

HTML code:

  <div class="wrapper">
     <div class="mask">Something</div> 
  </div>

jQuery:

    var fade = function(){
        $(".mask").fadeToggle(500,function(){
            $(this).parent().on("click",function(){
                $(this).off("click");
                fade();
            });
        });
    };

    $(".wrapper").on("click",function(){
        $(this).off("click");
        fade();     
    });

What's wrong with CASE for this? In order to see the result, you'll need at least a byte, and that's what you get with a single character.

CASE WHEN COLUMN1 = COLUMN2 THEN '1' ELSE '0' END AS MyDesiredResult

should work fine, and for all intents and purposes accomplishes the same thing as using a bit field.

if you are on Linux (Ubuntu)... the go to File-> Settings-> Plugin and select plugin from respective location.

If you are on Mac OS... the go to File-> Preferences-> Plugin and select plugin from respective location.

Use the system function.

system("myfile.sh"); // myfile.sh should be chmod +x

You also can lead your initial string, which you are going to check for pattern matching, to lower case. And using in your pattern lower case symbols respectively .

var name = 'john';
document.write(name);

it will write the variable you have declared upper

Use this one

public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

@Test
public void testInsertObject() throws Exception { 
    String url = BASE_URL + "/object";
    ObjectBean anObject = new ObjectBean();
    anObject.setObjectId("33");
    anObject.setUserId("4268321");
    //... more
    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRAP_ROOT_VALUE, false);
    ObjectWriter ow = mapper.writer().withDefaultPrettyPrinter();
    String requestJson=ow.writeValueAsString(anObject );

    mockMvc.perform(post(url).contentType(APPLICATION_JSON_UTF8)
        .content(requestJson))
        .andExpect(status().isOk());
}

As described in the comments, this works because the object is converted to json and passed as the request body. Additionally, the contentType is defined as Json (APPLICATION_JSON_UTF8).

First you can give JavaScript's Date object (class) the new method 'fromYMD()' for converting MySQL's YMD date format into JavaScript format by splitting YMD format into components and using these date components:

Date.prototype.fromYMD=function(ymd)
{
  var t=ymd.split(/[- :]/); //split into components
  return new Date(t[0],t[1]-1,t[2],t[3]||0,t[4]||0,t[5]||0);
};

Now you can define your own object (funcion in JavaScript world):

function DateFromYMD(ymd)
{
  return (new Date()).fromYMD(ymd);
}

and now you can simply create date from MySQL date format;

var d=new DateFromYMD('2016-07-24');

What you may want is

int x = reinterpret_cast<int>(arg);

This allows you to reinterpret the void * as an int.

CPANEL solution

Go to Cpanel, look for Remote MySQL. Add the the IP in the input field:

Host (% wildcard is allowed)

Comment to remember what IP that is. That was it for me.

I might be very late to answer this question but this is what has worked for me and it might help someone to get back on the development track!

nvm install v12.0 // You may need to install nvm, if not already done
rm -rd node_modules/
npm cache clean --force
npm install

Cheers!!

I've created an API to create an Excel file more easier.

Create Excel - Creating Excel from Template

Just set the required values upon instantiation then invoke execute(), it will be created based on your desired output directory.

But before you use this, you must have an Excel Template which will be use as a template of the newly created Excel file.

Also, you need Apache POI in your project's class path.

There is no definitive answer to this, as each browser has its own configuration for this, and this configuration may be changed. If you search on the internet you can find ways to change this limit (usually they're branded as "performance enhancement methods.") It might be worth advising your users to do so if it is required by your website.

Here's some nice and clean syntax on Angular's NgIf and using the else statement. In short, you will declare an ElementRef on an element and then reference it in the else block:

<div *ngIf="isLoggedIn; else loggedOut">
   Welcome back, friend.
</div>

<ng-template #loggedOut>
  Please friend, login.
</ng-template>

I've taken this example from NgIf, Else, Then which I found to be really well explained.

It also demonstrates using the <ng-template> syntax:

<ng-template [ngIf]="isLoggedIn" [ngIfElse]="loggedOut">
  <div>
    Welcome back, friend.
  </div>
</ng-template>

<ng-template #loggedOut>
  <div>
    Please friend, login.
  </div>
</ng-template>

And also using <ng-container> if that's what you're after:

<ng-container
  *ngIf="isLoggedIn; then loggedIn; else loggedOut">
</ng-container>

<ng-template #loggedIn>
  <div>
    Welcome back, friend.
  </div>
</ng-template>
<ng-template #loggedOut>
  <div>
    Please friend, login.
  </div>
</ng-template>

Source is taken from here on Angular's NgIf and Else syntax. I hope this helped! Enjoy.

The second parameter of the callback function passed to each() will contain the actual DOM element and not a jQuery wrapper object. You can call the getAttribute() method of the element:

$('#category_sorting_form_save').click(function() {
    var elements = $("#category_sorting_elements > div");
    $.each(elements, function(key, value) {
        console.info(key, ": ", value);
        console.info("cat_id: ", value.getAttribute('cat_id'));
    });
});

Or wrap the element in a jQuery object yourself:

$('#category_sorting_form_save').click(function() {
    var elements = $("#category_sorting_elements > div");
    $.each(elements, function(key, value) {
        console.info(key, ": ", value);
        console.info("cat_id: ", $(value).attr('cat_id'));
    });
});

Or simply use $(this):

$('#category_sorting_form_save').click(function() {
    var elements = $("#category_sorting_elements > div");
    $.each(elements, function() {
        console.info("cat_id: ", $(this).attr('cat_id'));
    });
});

Just try this:

<button type="button">Click Me</button>
<p></p>
<script type="text/javascript">
    $(document).ready(function(){
        $("button").click(function(){

            $.ajax({
                type: 'POST',
                url: 'script.php',
                success: function(data) {
                    alert(data);
                    $("p").text(data);

                }
            });
   });
});
</script>

In script.php

<?php 
  echo "You win";
 ?>

I had a similar problem and I did something like the below mentioned steps with my Path environment variable to fix the problem

1. Located where my Anaconda3 was installed. I run Windows 7. Mine is located at C:\ProgramData\Anaconda3.

2. Open Control Panel - System - Advanced System Settings, under Advanced tab click on Environment Variables.

3. Under System Variables, located "Path" add the following: C:\ProgramData\Anaconda3\Scripts;C:\ProgramData\Anaconda3\;

Save and open new terminal. type in "conda". It worked for me.

Hope these steps help

OK guys, I read (tried on Windows) all the previous stuff and all of these answers have their own disadvantages.

For the best way to update Node.js (at least for me), go to https://nodejs.org/en/ Then download the last version and install it in same folder you installed the previous version in - 1 min and it's done. You don't need to remove any old files.

Then update npm typing in cmd: npm install --save latest-version

Look at https://stackoverflow.com/a/4726838/2963099

Turn off pre compiled headers:

Project Properties -> C++ -> Precompiled Headers

set Precompiled Header to "Not Using Precompiled Header".

This might be adequate in circumstances where you can't define the function in advance (like in a bookmarklet):

myData.sort().filter(function(el,i,a){return i===a.indexOf(el)})

Directly from the node.js tag wiki, make sure watch some of the talk videos linked there to get a better idea.

Node.js is an event based, asynchronous I/O framework that uses Google's V8 JavaScript Engine.

Node.js - or just Node as it's commonly called - is used for developing applications that make heavy use of the ability to run JavaScript both on the client, as well as on server side and therefore benefit from the re-usability of code and the lack of context switching.

It's also possible to use matured JavaScript frameworks like YUI and jQuery for server side DOM manipulation.

To ease the development of complex JavaScript further, Node.js supports the CommonJS standard that allows for modularized development and the distribution of software in packages via the Node Package Manager.

Applications that can be written using Node.js include, but are not limited to:

• Static file servers
• Web Application frameworks
• Messaging middle ware
• Servers for HTML5 multi player games

I uninstalled ASP.NET MVC 4 using the Windows Control Panel, then reinstalled it by running AspNetMVC4Setup.exe (which I got from https://www.microsoft.com/en-us/download/details.aspx?id=30683), and that fixed the issue for me.

In other words, I didn't need to use Nuget or Visual Studio.

To rename a directory or file (I don't know much about complex cases, so there might be some caveats):

git filter-repo --path-rename OLD_NAME:NEW_NAME

To rename a directory in files that mention it (it's possible to use callbacks, but I don't know how):

git filter-repo --replace-text expressions.txt

expressions.txt is a file filled with lines like literal:OLD_NAME==>NEW_NAME (it's possible to use Python's RE with regex: or glob with glob:).

To rename a directory in messages of commits:

git-filter-repo --message-callback 'return message.replace(b"OLD_NAME", b"NEW_NAME")'

Python's regular expressions are also supported, but they must be written in Python, manually.

If the repository is original, without remote, you will have to add --force to force a rewrite. (You may want to create a backup of your repository before doing this.)

If you do not want to preserve refs (they will be displayed in the branch history of Git GUI), you will have to add --replace-refs delete-no-add.

@article = user.articles.build(:title => "MainTitle")
@article.save

I see 4 issues with your code:

• In your timer method you are always setting your current count to 10
• You try to update the state in render method
• You do not use setState method to actually change the state
• You are not storing your intervalId in the state

Let's try to fix that:

componentDidMount: function() {
   var intervalId = setInterval(this.timer, 1000);
   // store intervalId in the state so it can be accessed later:
   this.setState({intervalId: intervalId});
},

componentWillUnmount: function() {
   // use intervalId from the state to clear the interval
   clearInterval(this.state.intervalId);
},

timer: function() {
   // setState method is used to update the state
   this.setState({ currentCount: this.state.currentCount -1 });
},

render: function() {
    // You do not need to decrease the value here
    return (
      <section>
       {this.state.currentCount}
      </section>
    );
}

This would result in a timer that decreases from 10 to -N. If you want timer that decreases to 0, you can use slightly modified version:

timer: function() {
   var newCount = this.state.currentCount - 1;
   if(newCount >= 0) { 
       this.setState({ currentCount: newCount });
   } else {
       clearInterval(this.state.intervalId);
   }
},

Enabeling GZip in Tomcat doesn't worked in my Spring Boot Project. I used CompressingFilter found here.

@Bean
public Filter compressingFilter() {
    CompressingFilter compressingFilter = new CompressingFilter();
    return compressingFilter;
}

The best way to fix it I have looked for the code or trick how to center nav menu and found the real solutions it works for all browsers and for my friends ;)

Here is how I have done:

body {
    margin: 0;
    padding: 0;
}

div maincontainer {
    margin: 0 auto;
    width: ___px;
    text-align: center;
}

ul {
    margin: 0;
    padding: 0;
}

ul li {
    margin-left: auto;
    margin-right: auto;
}

and do not forget to set doctype html5

Sometimes this issue comes because the java.version which you have mentioned in POM.xml is not the one installed in your machine.

<properties>
    <java.version>1.7</java.version>
</properties>

Ensure you exactly mention the same version in your pom.xml as the jdk and jre version present in your machine.

If you want to migrate the repo including the wiki and all issues and milestones, you can use node-gitlab-2-github and GitLab to GitHub migration

Or, you could do it the really simple way.

Dim OpenCMD 
OpenCMD = CreateObject("wscript.shell")
OpenCMD.run("Command Goes Here")

As Brian said:

According to a post on xda-developers, you can enable ADB over WiFi from the device with the commands

setprop service.adb.tcp.port 5555

stop adbd

start adbd

And you can disable it and return ADB to listening on USB with

setprop service.adb.tcp.port -1

stop adbd

start adbd

If you have USB access already, it is even easier to switch to using WiFi. From a command line on the computer that has the device connected via USB, issue the commands

adb tcpip 5555

adb connect 192.168.0.101:5555

To tell the ADB daemon return to listening over USB

adb usb

There are also several apps on the Android Market that automate this process.

It works.You just need to access the android shell and type those commands...

One other (easier) solution is on the Market: adbWireless, it will automatically set your phone.

Root is required! for both...

The selector returns an array of jQuery objects. If no matching elements are found, it returns an empty array. You can check the .length of the collection returned by the selector or check whether the first array element is 'undefined'.

You can use any the following examples inside an IF statement and they all produce the same result. True, if the selector found a matching element, false otherwise.

$('#notAnElement').length > 0
$('#notAnElement').get(0) !== undefined
$('#notAnElement')[0] !== undefined

Additionally to what Chris Taylor wrote: if you have something serialized as an attribute, you can have a property on your class named {PropertyName}Specified to control if it should be serialized. In code:

public class MyClass
{
    [XmlAttribute]
    public int MyValue;

    [XmlIgnore]
    public bool MyValueSpecified;
}

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

I had the same problem yesterday :-)

$("#SelectedCountryId option:selected").text()

I also read that this is slow, if you want to use it often you should probably use something else.

I don't know why yours is not working, this one is for me, maybe someone else can help...

If you have one or more EditTexts inside of a recyclerview items, disable the autofocus of these, putting this configuration in the parent view of recyclerview:

android:focusable="true"
android:focusableInTouchMode="true"

I had this issue when I started another activity launched from a recyclerview item, when I came back and set an update of one field in one item with notifyItemChanged(position) the scroll of RV moves, and my conclusion was that, the autofocus of EditText Items, the code above solved my issue.

best.

In Python 3, we use the bytes object, also known as str in Python 2.

# Python 3
key = bytes([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])

# Python 2
key = ''.join(chr(x) for x in [0x13, 0x00, 0x00, 0x00, 0x08, 0x00])

I find it more convenient to use the base64 module...

# Python 3
key = base64.b16decode(b'130000000800')

# Python 2
key = base64.b16decode('130000000800')

You can also use literals...

# Python 3
key = b'\x13\0\0\0\x08\0'

# Python 2
key = '\x13\0\0\0\x08\0'

The below code will give you list of all the rows:-

df[df['C'] != 'XYZ']

To store the values from the above code into a dataframe :-

newdf = df[df['C'] != 'XYZ']

Assuming fairly simple usage (no escaping of the delimiter, for example), you can use grep:

$ echo "1:2:3:4:5" | grep -oE "[^:]+$"
5

Breakdown - find all the characters not the delimiter ([^:]) at the end of the line ($). -o only prints the matching part.

try this:

SELECT * FROM TableA
JOIN TableB ON TableA.primary_key = TableB.foreign_key 
JOIN TableB ON TableB.foreign_key = TableC.foreign_key

On Postgres 10:

SELECT to_timestamp(CAST(epoch_ms as bigint)/1000)

The problem is in the import line. You are importing a module, not a class. Assuming your file is named other_file.py (unlike java, again, there is no such rule as "one class, one file"):

from other_file import findTheRange

if your file is named findTheRange too, following java's convenions, then you should write

from findTheRange import findTheRange

you can also import it just like you did with random:

import findTheRange
operator = findTheRange.findTheRange()

Some other comments:

a) @Daniel Roseman is right. You do not need classes here at all. Python encourages procedural programming (when it fits, of course)

b) You can build the list directly:

  randomList = [random.randint(0, 100) for i in range(5)]

c) You can call methods in the same way you do in java:

largestInList = operator.findLargest(randomList)
smallestInList = operator.findSmallest(randomList)

d) You can use built in function, and the huge python library:

largestInList = max(randomList)
smallestInList = min(randomList)

e) If you still want to use a class, and you don't need self, you can use @staticmethod:

class findTheRange():
    @staticmethod
    def findLargest(_list):
        #stuff...

Update January 2016

Really surprised no-one has suggested:

lsof -i :PORT_NUMBER

to get the basic information required. For instance, checking on port 1337:

lsof -i :1337

Other variations, depending on circumstances:

sudo lsof -i :1337
lsof -i tcp:1337

You can easily build on this to extract the PID itself. For example:

lsof -t -i :1337

which is also equivalent (in result) to this command:

lsof -i :1337 | awk '{ print $2; }' | head -n 2 | grep -v PID

Quick illustration:

For completeness, because frequently used together:

To kill the PID:

kill -9 <PID>
# kill -9 60401

or as a one liner:

kill -9 $(lsof -t -i :1337)

When I tried "react-native run-android" I was receiving errors "Could not initialize class org.codehaus.groovy.runtime.InvokerHelper" + "Failed to install the app. Make sure you have the Android development environment set up"....

Solved it by updating the gradle in Android Studio. When I opened my project in Android Studio it showed a message asking to update Gradle, and I just clicked.

I'm adding my comment as an answer because it solves the original problem for a wider range of cases than the accepted answer. Note: you must still know the maximum length and the approximate proportion of multi-byte characters that your data will have.

If you have a CLOB greater than 4000 bytes, you need to use DBMS_LOB.SUBSTR rather than SUBSTR. Note that the amount and offset parameters are reversed in DBMS_LOB.SUBSTR.

Next, you may need to substring an amount less than 4000, because this parameter is the number of characters, and if you have multi-byte characters then 4000 characters will be more than 4000 bytes long, and you'll get ORA-06502: PL/SQL: numeric or value error: character string buffer too small because the substring result needs to fit in a VARCHAR2 which has a 4000 byte limit. Exactly how many characters you can retrieve depends on the average number of bytes per character in your data.

So my answer is:

LENGTHB(TO_CHAR(DBMS_LOB.SUBSTR(<CLOB-Column>,3000,1)))
+NVL(LENGTHB(TO_CHAR(DBM??S_LOB.SUBSTR(<CLOB-Column>,3000,3001))),0)
+NVL(LENGTHB(TO_CHAR(DBM??S_LOB.SUBSTR(<CLOB-Column>,6000,6001))),0)
+...

where you add as many chunks as you need to cover your longest CLOB, and adjust the chunk size according to average bytes-per-character of your data.

What I use to get the desired outcome is:

1. Save the below code block in a file named toggle_cell.py in the same directory as of your notebook

from IPython.core.display import display, HTML
toggle_code_str = '''
<form action="javascript:code_toggle()"><input type="submit" id="toggleButton" value="Show Sloution"></form>
'''

toggle_code_prepare_str = '''
    <script>
    function code_toggle() {
        if ($('div.cell.code_cell.rendered.selected div.input').css('display')!='none'){
            $('div.cell.code_cell.rendered.selected div.input').hide();
        } else {
            $('div.cell.code_cell.rendered.selected div.input').show();
        }
    }
    </script>

2. Add the following in the first cell of your notebook

from toggle_cell import toggle_code as hide_sloution

3. Any cell you need to add the toggle button to simply call hide_sloution()

This is a variation to the answer provided by @Metrics and edited by @Max Ghenis...

l <- sapply(iris, function(x) is.factor(x))
m <- iris[,l]

n <- sapply( m, function(x) { y <- summary(x)/length(x)
len <- length(y[y<0.005 | y>0.995])
cbind(len,t(y))} )

drop_cols_df <- data.frame(var = names(l[l]), 
                           status = ifelse(as.vector(t(n[1,]))==0,"NODROP","DROP" ),
                           level1 = as.vector(t(n[2,])),
                           level2 = as.vector(t(n[3,])))

Here, after identifying factor variables, the second sapply computes what percent of records belong to each level / category of the variable. Then it identifies number of levels over 99.5% or below 0.5% incidence rate (my arbitrary thresholds).

It then goes on to return the number of valid levels and the incidence rate of each level in each categorical variable.

Variables with zero levels crossing the thresholds should not be dropped, while the other should be dropped from the linear model.

The last data frame makes viewing the results easy. It's hard coded for this data set since all factor variables are binomial. This data frame can be made generic easily enough.

This is also working at my end...

<div style="width: 100px; height: 100px; float: left; position: relative;">
    <div
        style="width: 100%; height: 40px; position: absolute; top: 50%; left: 0; margin-top: -20px; line-height:19px; text-align: center; z-index: 999999999999999">
        99%<Br />
        Total
    </div>
    <canvas id="chart-area" width="100" height="100" />
</div>

$("#Create").find(".myClass").add("#Edit .myClass").plugin({});

Use $.fn.add to concatenate two sets.

You'll need a using System.Net.Http at the top.

// Get the focused element:
var $focused = $(':focus');

// No jQuery:
var focused = document.activeElement;

// Does the element have focus:
var hasFocus = $('foo').is(':focus');

// No jQuery:
elem === elem.ownerDocument.activeElement;

Which one should you use? quoting the jQuery docs:

As with other pseudo-class selectors (those that begin with a ":"), it is recommended to precede :focus with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $(':focus') is equivalent to $('*:focus'). If you are looking for the currently focused element, $( document.activeElement ) will retrieve it without having to search the whole DOM tree.

The answer is:

document.activeElement

And if you want a jQuery object wrapping the element:

$(document.activeElement)

Save your username, password and sever name in an RDP file and run the RDP file from your script

you can try something like this:

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

Here is the output:

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

Not sure if you have all this setup, but for me I am using PHP and MYSQL. So I use a PHP class PHPExcel. This takes a file in nearly any format, xls, xlsx, cvs,... and then lets you read and / or insert.

So what I wind up doing is loading the excel in to a phpexcel object and then loop through all the rows. Based on what I want, I write a simple SQL insert command to insert the data in the excel file into my table.

On the front end it is a little work, but its just a matter of tweaking some of the existing code examples. But when you have it dialed in making changes to the import is simple and fast.

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

• TeX FAQ entry How to adjust list spacing
• http://dcwww.camd.dtu.dk/~schiotz/comp/LatexTips/LatexTips.html

Those files are created and used by Android Studio editor.

You don't need to check in those files to version control.

Git uses .gitignore file, that contains list of files and directories, to know the list of files and directories that don't need to be checked in.

Android studio automatically creates .gitingnore files listing all files and directories which don't need to be checked in to any version control.

When the button is clicked, get the value of the input and use it to create an image element which is appended to the body (or anywhere else) :

<html>
<body>
<form>
    <input type="text" id="imagename" value="" />
    <input type="button" id="btn" value="GO" />
</form>
    <script type="text/javascript">
        document.getElementById('btn').onclick = function() {
            var val = document.getElementById('imagename').value,
                src = 'http://webpage.com/images/' + val +'.png',
                img = document.createElement('img');

            img.src = src;
            document.body.appendChild(img);
        }
    </script>
</body>
</html>

FIDDLE

the same in jQuery:

$('#btn').on('click', function() {
    var img = $('<img />', {src : 'http://webpage.com/images/' + $('#imagename').val() +'.png'});
    img.appendTo('body');
});

How do I add a junit 4 dependency correctly?

Assuming you're resolving against a standard Maven (or equivalent) repo:

dependencies {
    ...
    testCompile "junit:junit:4.11"  // Or whatever version
}

Run those tests in the folders of tests/model?

You define your test source set the same way:

sourceSets {
    ...

    test {
        java {
            srcDirs = ["test/model"]  // Note @Peter's comment below
        }
    }
}

Then invoke the tests as:

./gradlew test

EDIT: If you are using JUnit 5 instead, there are more steps to complete, you should follow this tutorial.

That's not how you do it.

>>> ''.join(['first', 'second', 'other'])
'firstsecondother'

is what you want.

If you do it in a for loop, it's going to be inefficient as string "addition"/concatenation doesn't scale well (but of course it's possible):

>>> mylist = ['first', 'second', 'other']
>>> s = ""
>>> for item in mylist:
...    s += item
...
>>> s
'firstsecondother'

For MySQL, this can be shortened to:

SELECT distributor_id,
    COUNT(*) total,
    SUM(level = 'exec') ExecCount,
    SUM(level = 'personal') PersonalCount
FROM yourtable
GROUP BY distributor_id

You need CSS to achieve this, e.g.:

#container_2 {
    -webkit-transform: rotate(90deg);
    -moz-transform: rotate(90deg);
    -o-transform: rotate(90deg);
    -ms-transform: rotate(90deg);
    transform: rotate(90deg);
}

Demo:

#container_2 {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid red;_x000D_
  -webkit-transform: rotate(45deg);_x000D_
  -moz-transform: rotate(45deg);_x000D_
  -o-transform: rotate(45deg);_x000D_
  -ms-transform: rotate(45deg);_x000D_
  transform: rotate(45deg);_x000D_
}

<div id="container_2"></div>

(There's 45 degrees rotation in the demo, so you can see the effect)

Note: The -o- and -moz- prefixes are no longer relevant and probably not required. IE9 requires -ms- and Safari and the Android browser require -webkit-

Update 2018: Vendor prefixes are not needed anymore. Only transform is sufficient. (thanks @rinogo)

You are correct in that your list contains a reference to the original dictionary.

a.append(b.copy()) should do the trick.

Bear in mind that this makes a shallow copy. An alternative is to use copy.deepcopy(b), which makes a deep copy.

it's because the name of the submit button is named "submit", change it to anything but "submit", try "submitme" and retry it. It should then work.

Try this

if ($_POST['submit']) {
    $success= mail($to, $subject, $body, $from);
    if($success)
    { 
        echo '
        <p>Your message has been sent!</p>
        ';
    } else { 
        echo '
        <p>Something went wrong, go back and try again!</p>
        '; 
    }
}

My scenario was a bit different. I had an object with nested objects as well as functions. Therefore, Object.assign() and JSON.stringify() were not solutions to my problem. Using third-party libraries was not an option for me neither.

Hence, I decided to make a simple function to use built-in methods to copy an object with its literal properties, its nested objects, and functions.

let deepCopy = (target, source) => {
    Object.assign(target, source);
    // check if there's any nested objects
    Object.keys(source).forEach((prop) => {
        /**
          * assign function copies functions and
          * literals (int, strings, etc...)
          * except for objects and arrays, so:
          */
        if (typeof(source[prop]) === 'object') {
            // check if the item is, in fact, an array
            if (Array.isArray(source[prop])) {
                // clear the copied referenece of nested array
                target[prop] = Array();
                // iterate array's item and copy over
                source[prop].forEach((item, index) => {
                    // array's items could be objects too!
                    if (typeof(item) === 'object') {
                        // clear the copied referenece of nested objects
                        target[prop][index] = Object();
                        // and re do the process for nested objects
                        deepCopy(target[prop][index], item);
                    } else {
                        target[prop].push(item);
                    }
                });
            // otherwise, treat it as an object
            } else {
                // clear the copied referenece of nested objects
                target[prop] = Object();
                // and re do the process for nested objects
                deepCopy(target[prop], source[prop]);
            }
        }
    });
};

Here's a test code:

let a = {
    name: 'Human', 
    func: () => {
        console.log('Hi!');
    }, 
    prop: {
        age: 21, 
        info: {
            hasShirt: true, 
            hasHat: false
        }
    },
    mark: [89, 92, { exam: [1, 2, 3] }]
};

let b = Object();

deepCopy(b, a);

a.name = 'Alien';
a.func = () => { console.log('Wassup!'); };
a.prop.age = 1024;
a.prop.info.hasShirt = false;
a.mark[0] = 87;
a.mark[1] = 91;
a.mark[2].exam = [4, 5, 6];

console.log(a); // updated props
console.log(b);

For efficiency-related concerns, I believe this is the simplest and most efficient solution to the problem I had. I would appreciate any comments on this algorithm that could make it more efficient.

On Windows, you could use this command.

taskkill /F /IM <processname>.exe 

To kill it forcefully, you may use;

Runtime.getRuntime().exec("taskkill /F /IM <processname>.exe")

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

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

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

Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

For anaconda installation, first pick a channel which has the latest version of tensorflow binary. Usually, the latest versions are available at the channel conda-forge. Then simply do:

conda update -f -c conda-forge tensorflow

This will upgrade your existing tensorflow installation to the very latest version available. As of this writing, the latest version is 1.4.0-py36_0

It's a "precompiled header file" -- any headers you include in stdafx.h are pre-processed to save time during subsequent compilations. You can read more about it here on MSDN.

If you're building a cross-platform application, check "Empty project" when creating your project and Visual Studio won't put any files at all in your project.

Two things are happening here.

1. You are not using the container class properly.
2. You are trying to override Bootstrap's CSS for the container class

Bootstrap uses a grid system and the .container class is defined in its own CSS. The grid has to exist within a container class DIV. The container DIV is just an indication to Bootstrap that the grid within has that parent. Therefore, you cannot set the height of a container.

What you want to do is the following:

<div class="container-fluid"> <!-- this is to make it responsive to your screen width -->
    <div class="row">
        <div class="col-md-4 myClassName">  <!-- myClassName is defined in my CSS as you defined your container -->
            <img src="#.jpg" height="200px" width="300px">
        </div>
    </div>
</div>

Here you can find more info on the Bootstrap grid system.

That being said, if you absolutely MUST override the Bootstrap CSS then I would try using the "!important" clause to my CSS definition as such...

.container {
   padding-right: 15px;
   padding-left: 15px;
   margin-right: auto;
   margin-left: auto;
   max-width: 900px;
   overflow:hidden;
   min-height:0px !important;
}

But I have always found that the "!important" clause just makes for messy CSS.

This can also come if the target folder is used by some other processes. Close all the programs which may use the target folder and try.

You may use resource monitor(windows tool) to check the processes which uses your target folder.

This worked for me!.

Options to avoid using SecurityContextHolder in tests:

• Option 1: use mocks - I mean mock SecurityContextHolder using some mock library - EasyMock for example
• Option 2: wrap call SecurityContextHolder.get... in your code in some service - for example in SecurityServiceImpl with method getCurrentPrincipal that implements SecurityService interface and then in your tests you can simply create mock implementation of this interface that returns the desired principal without access to SecurityContextHolder.

For SQL Server 2000 and above, I prefer the following parsing of Joe's answer:

declare @sqlVers numeric(4,2)
select @sqlVers = left(cast(serverproperty('productversion') as varchar), 4)

Gives results as follows:

Result   Server Version
8.00     SQL 2000
9.00     SQL 2005
10.00    SQL 2008
10.50    SQL 2008R2
11.00    SQL 2012
12.00    SQL 2014

I resolved the issue by converting the source feed from http://www.news18.com/rss/politics.xml to https://www.news18.com/rss/politics.xml

with http below code was creating an empty file which was causing the issue down the line

    String feedUrl = "https://www.news18.com/rss/politics.xml"; 
    File feedXmlFile = null;

    try {
    feedXmlFile =new File("C://opinionpoll/newsFeed.xml");
    FileUtils.copyURLToFile(new URL(feedUrl),feedXmlFile);


          DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
          DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
          Document doc = dBuilder.parse(feedXmlFile);

Just found a post Atomic vs. Non-Atomic Operations to be very helpful to me.

"An operation acting on shared memory is atomic if it completes in a single step relative to other threads.

When an atomic store is performed on a shared memory, no other thread can observe the modification half-complete.

When an atomic load is performed on a shared variable, it reads the entire value as it appeared at a single moment in time."

Just try this, it explains it pretty much itself. You can't create a view with an ORDER BY except if...

CREATE VIEW v_Test
         AS
           SELECT name
             FROM sysobjects
         ORDER BY name
        GO

Msg 1033, Level 15, State 1, Procedure TestView, Line 5 The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.

Another option would be to use the IIS URL Rewrite module to map the virtual bundle image folder to the physical image folder. Below is an example of a rewrite rule from that you could use for a bundle called "~/bundles/yourpage/styles" - note the regex matches on alphanumeric characters as well as hyphens, underscores and periods, which are common in image file names.

<rewrite>
  <rules>
    <rule name="Bundle Images">
      <match url="^bundles/yourpage/images/([a-zA-Z0-9\-_.]+)" />
      <action type="Rewrite" url="Content/css/jquery-ui/images/{R:1}" />
    </rule>
  </rules>
</rewrite>

This approach creates a little extra overhead, but allows you to have more control over your bundle names, and also reduces the number of bundles you may have to reference on one page. Of course, if you have to reference multiple 3rd party css files that contain relative image path references, you still can't get around creating multiple bundles.

Try the code below:

Batchfile.bat:

cd c:\batchfilepath
net stop "SQL Server Reporting Services (MSSQLSERVER)" 
timeout /t 10
net start "SQL Server Reporting Services (MSSQLSERVER)"

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Attributes.Add("style", "cursor:help;");
    if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowState == DataControlRowState.Alternate)
    { 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {                
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#E56E94'");
            e.Row.BackColor = Color.FromName("#E56E94");                
        }           
    }
    else
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='gray'");
            e.Row.BackColor = Color.FromName("gray");                
        }           
    }
}

Use css:

<style>
input[name=btnsubmit]:active {
color: green;
}
</style>

One interesting thing is we can view the tables horizontally, without folding. we can use PAGER environment variable. psql makes use of it. you can set

export PAGER='/usr/bin/less -S'

or just less -S if its already availble in command line, if not with the proper location. -S to view unfolded lines. you can pass in any custom viewer or other options with it.

I've written more in Psql Horizontal Display

The problem is not with the Event type, but that the EventTarget interface in typescript only has 3 methods:

interface EventTarget {
    addEventListener(type: string, listener: EventListenerOrEventListenerObject, useCapture?: boolean): void;
    dispatchEvent(evt: Event): boolean;
    removeEventListener(type: string, listener: EventListenerOrEventListenerObject, useCapture?: boolean): void;
}

interface SyntheticEvent {
    bubbles: boolean;
    cancelable: boolean;
    currentTarget: EventTarget;
    defaultPrevented: boolean;
    eventPhase: number;
    isTrusted: boolean;
    nativeEvent: Event;
    preventDefault(): void;
    stopPropagation(): void;
    target: EventTarget;
    timeStamp: Date;
    type: string;
}

So it is correct that name and value don't exist on EventTarget. What you need to do is to cast the target to the specific element type with the properties you need. In this case it will be HTMLInputElement.

update = (e: React.SyntheticEvent): void => {
    let target = e.target as HTMLInputElement;
    this.props.login[target.name] = target.value;
}

Also for events instead of React.SyntheticEvent, you can also type them as following: Event, MouseEvent, KeyboardEvent...etc, depends on the use case of the handler.

The best way to see all these type definitions is to checkout the .d.ts files from both typescript & react.

Also check out the following link for more explanations: Why is Event.target not Element in Typescript?

Same thing.. makes no difference at all... htm was used in the days where only 3 letter extensions were common.

For True, not None:

if foo:

For false, None:

if not foo:

try following js code

Brendan is correct. You can edit the Select command to edit a filtered list of records. For instance "WHERE dept_no = 200".

#since this was yesterday
date -dyesterday +%Y%m%d

#more precise, and more recommended
date -d'27 JUN 2011' +%Y%m%d

#assuming this is similar to yesterdays `date` question from you 
#http://stackoverflow.com/q/6497525/638649
date -d'last-monday' +%Y%m%d

#going on @seth's comment you could do this
DATE="27 jun 2011"; date -d"$DATE" +%Y%m%d

#or a method to read it from stdin
read -p "  Get date >> " DATE; printf "  AS YYYYMMDD format >> %s"  `date
-d"$DATE" +%Y%m%d`    

#which then outputs the following:
#Get date >> 27 june 2011   
#AS YYYYMMDD format >> 20110627

#if you really want to use awk
echo "27 june 2011" | awk '{print "date -d\""$1FS$2FS$3"\" +%Y%m%d"}' | bash

#note | bash just redirects awk's output to the shell to be executed
#FS is field separator, in this case you can use $0 to print the line
#But this is useful if you have more than one date on a line

note this only works on GNU date

I have read that:

Solaris version of date, which is unable to support -d can be resolve with replacing sunfreeware.com version of date

What you should get as output with this code is:

Array ()

... this is exactly how you get just one row, you don't need a while loop. Are you sure you're printing the right variable?

Just append a hash with an ID of an element to the URL. E.g.

<div id="about"></div>

and

http://mysite.com/#about

So the link would look like:

<a href="http://mysite.com/#about">About</a>

or just

<a href="#about">About</a>

As others have pointed out, accessing dicts in Python is fast. They are probably the best-oiled data structure in the language, given their central role. The problem lies elsewhere.

How many tuples are you memoizing? Have you considered the memory footprint? Perhaps you are spending all your time in the memory allocator or paging memory.

You can also pass the function of a struct, like:

    package main
    // define struct
    type Apple struct {}
    
    // return apple's color
    func (Apple) GetColor() string {
         return "Red" 
    }
    
    func main () {
        // instantiate
        myApple := Apple{}
        
        // put the func in a variable
        theFunc := myApple.GetColor
        
        // execute the variable as a function
        color := theFunc()
    
        print(color)
    }

output will be "Red", check on the playground

This function work like a charm

function toggle_full_screen()
{
    if ((document.fullScreenElement && document.fullScreenElement !== null) || (!document.mozFullScreen && !document.webkitIsFullScreen))
    {
        if (document.documentElement.requestFullScreen){
            document.documentElement.requestFullScreen();
        }
        else if (document.documentElement.mozRequestFullScreen){ /* Firefox */
            document.documentElement.mozRequestFullScreen();
        }
        else if (document.documentElement.webkitRequestFullScreen){   /* Chrome, Safari & Opera */
            document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
        }
        else if (document.msRequestFullscreen){ /* IE/Edge */
            document.documentElement.msRequestFullscreen();
        }
    }
    else
    {
        if (document.cancelFullScreen){
            document.cancelFullScreen();
        }
        else if (document.mozCancelFullScreen){ /* Firefox */
            document.mozCancelFullScreen();
        }
        else if (document.webkitCancelFullScreen){   /* Chrome, Safari and Opera */
            document.webkitCancelFullScreen();
        }
        else if (document.msExitFullscreen){ /* IE/Edge */
            document.msExitFullscreen();
        }
    }
}

To use it just call:

toggle_full_screen();

Please let me state the obvious: note that adding neither break nor continue, will resume your program; i.e. I trapped for a certain error, then after logging it, I wanted to resume processing, and there were more code tasks in between the next row, so I just let it fall through.

On my Samsung galaxy mini S5570 (after got root on cellphone):

Fist, as root, I ran:

systemctl start adb

as a normal user:

adb shell 
su 

Grant root permissions on touch screen

mount 

list all mount points that we have and we can see, in my case, that /dev/stl12 was mounted on /system as ro (ready only), so we just need do:

mount -o rw,remount /dev/stl12 /system

For Java 8 you can use the following command line to get the heap space utilization in kB:

jstat -gc <PID> | tail -n 1 | awk '{split($0,a," "); sum=a[3]+a[4]+a[6]+a[8]; print sum}'

The command basically sums up:

• S0U: Survivor space 0 utilization (kB).
• S1U: Survivor space 1 utilization (kB).
• EU: Eden space utilization (kB).
• OU: Old space utilization (kB).

You may also want to include the metaspace and the compressed class space utilization. In this case you have to add a[10] and a[12] to the awk sum.

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

    You can achieve this by using cssSelector 
    // Use of List web elements:
    String cssSelectorOfLoginButton="input[type='button'][id='login']"; 
    //****Add cssSelector of your 1st webelement
    //List<WebElement> button 
    =driver.findElements(By.cssSelector(cssSelectorOfLoginButton));
    button.get(0).click();

    I hope this work for you

The following code is perfectly fine and the right way (most exact, concise, and clear) to check if an object is null:

object obj = null;

//...

if (obj == null)
{
    // Do something
}

String.IsNullOrEmpty is a method existing for convenience so that you don't have to write the comparison code yourself:

private bool IsNullOrEmpty(string input)
{
    return input == null || input == string.Empty;
}

Additionally, there is a String.IsNullOrWhiteSpace method checking for null and whitespace characters, such as spaces, tabs etc.

First off, (though this won't change the performance at all) consider cleaning up your code, similar to this:

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

x = np.arange(0, 2*np.pi, 0.01)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
lines = [ax.plot(x, y, style)[0] for ax, style in zip(axes, styles)]

fig.show()

tstart = time.time()
for i in xrange(1, 20):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    fig.canvas.draw()

print 'FPS:' , 20/(time.time()-tstart)

With the above example, I get around 10fps.

Just a quick note, depending on your exact use case, matplotlib may not be a great choice. It's oriented towards publication-quality figures, not real-time display.

However, there are a lot of things you can do to speed this example up.

There are two main reasons why this is as slow as it is.

1) Calling fig.canvas.draw() redraws everything. It's your bottleneck. In your case, you don't need to re-draw things like the axes boundaries, tick labels, etc.

2) In your case, there are a lot of subplots with a lot of tick labels. These take a long time to draw.

Both these can be fixed by using blitting.

To do blitting efficiently, you'll have to use backend-specific code. In practice, if you're really worried about smooth animations, you're usually embedding matplotlib plots in some sort of gui toolkit, anyway, so this isn't much of an issue.

However, without knowing a bit more about what you're doing, I can't help you there.

Nonetheless, there is a gui-neutral way of doing it that is still reasonably fast.

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

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

fig.show()

# We need to draw the canvas before we start animating...
fig.canvas.draw()

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]

tstart = time.time()
for i in xrange(1, 2000):
    items = enumerate(zip(lines, axes, backgrounds), start=1)
    for j, (line, ax, background) in items:
        fig.canvas.restore_region(background)
        line.set_ydata(np.sin(j*x + i/10.0))
        ax.draw_artist(line)
        fig.canvas.blit(ax.bbox)

print 'FPS:' , 2000/(time.time()-tstart)

This gives me ~200fps.

To make this a bit more convenient, there's an animations module in recent versions of matplotlib.

As an example:

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

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

def animate(i):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    return lines

# We'd normally specify a reasonable "interval" here...
ani = animation.FuncAnimation(fig, animate, xrange(1, 200), 
                              interval=0, blit=True)
plt.show()

./bilet.sh: line 6: [: 7]: integer expression expected

Be careful with " "

./bilet.sh: line 9: [: missing `]'

This is because you need to have space between brackets like:

if [ "$age" -le 7 ] -o [ "$age" -ge 65 ]

look: added space, and no " "

I was looking long and hard for a solution to this problem and the best I found was a root FTP server on the phone that you connect to on Windows with an FTP client like FileZilla, on the same WiFi network of course.

The root FTP server app I ended up using is FTP Droid. I tried a lot of other FTP apps with bigger download numbers but none of them worked for me for whatever reason. So install this app and set a user with home as / or wherever you want.

Then make note of the phone IP and connect with FileZilla and you should have access to the root of the phone. The biggest benefit I found is I can download entire folders and FTP will just queue it up and take care of it. So I downloaded all of my /data/data/ folder when I was looking for an app and could search on my PC. Very handy.

Using dplyr package we can filter NA as follows:

dplyr::filter(df,  !is.na(columnname))

If you want to set through xml using android's default color codes, then you need to do as below:

android:background="@android:color/white"

If you have colors specified in your project's colors.xml, then use:

android:background="@color/white"

If you want to do programmatically, then do:

linearlayout.setBackgroundColor(Color.WHITE);

Similar to this question.

In essence it means that the method Bar will not modify non mutable member variables of Foo.

Outdated answer: It is now implemented in major browsers, see the other answers to this question.

CSS3 has modified the specification of background-position so that it will work with different origin point. Unfortunately, I can't find any evidence that it is implemented yet in any major browsers.

http://www.w3.org/TR/css3-background/#the-background-position See example 12.

background-position: right 3em bottom 10px;

You must use Eclipse WTP (Web Tool Platform), and should use the lastest version is Luna 4.4. Link download: Eclipse IDE for Java EE Developers http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/lunar

Menu Windows\Show view\Other, choose folder Server, click on Servers.





Right click on blank area to use context menu, choose New\Server

Choose "GlassFish Tools" from Oracle vendor.



Then, restart Eclipse.

• Or you download GlassFish tools (Supports GlassFish 4.0 and 3.1) from: https://marketplace.eclipse.org/content/glassfish-tools and install manually.

• Read more about creating a server: http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.wst.server.ui.doc.user%2Ftopics%2Ftwcrtins.html

I don't like and understand things, which can be explained visually, by words.

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

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

Try using a wildcard like this

=VLOOKUP(LEFT(A1,3)&"*",B$2:B$22,1,FALSE)

so if A1 is "barry" that formula will return the first value in B2:B22 that starts with "bar"

sizeof returns the size of the type of the variable in bytes. So in your case it's returning the size of your char[7] which is 7 * sizeof(char). Since sizeof(char) = 1, the result is 7.

Expanding this to another example:

int intArr[5];
printf("sizeof(intArr)=%u", sizeof(intArr));

would yield 5 * sizeof(int), so you'd get the result "20" (At least on a regular 32bit platform. On others sizeof(int) might differ)

To return to your problem:

It seems like, that what you want to know is the length of the string which is contained inside your array and not the total array size.

By definition C-Strings have to be terminated with a trailing '\0' (0-Byte). So to get the appropriate length of the string contained within your array, you have to first terminate the string, so that you can tell when it's finished. Otherwise there would be now way to know.

All standard functions build upon this definition, so if you call strlen to retrieve the str ing len gth, it will iterate through the given array until it finds the first 0-byte, which in your case would be the very first element.

Another thing you might need to know that only because you don't fill the remaining elements of your char[7] with a value, they actually do contain random undefined values.

Hope that helped.

For me, it was just close the android studio and restart as Administrator.

Why not just use separate console.log() for each var, and separate with a comma rather than converting them all to strings? That would give you separate lines, AND give you the true value of each variable rather than the string representation of each (assuming they may not all be strings).

console.log('roleName',roleName);
console.log('role_ID',role_ID);
console.log('modal_ID',modal_ID);
console.log('related',related);

And I think it would be easier to read/maintain.

Given points (X1,Y1) and (X2,Y2) then:

dX = X1 - X2;
dY = Y1 - Y2;

You can manage it with a double cast :

@SuppressWarnings("unchecked") Class<List<Foo>> cls = (Class<List<Foo>>)(Object)List.class

I was over-complicating myself. After taking a long break and coming back, the desired output could be accomplished by this simple query:

SELECT Sandwiches.[Sandwich Type], Sandwich.Bread, Count(Sandwiches.[SandwichID]) AS [Total Sandwiches]
FROM Sandwiches
GROUP BY Sandwiches.[Sandwiches Type], Sandwiches.Bread;

Thanks for answering, it helped my train of thought.

You can use toArray() of eloquent as below.

The toArray method converts the collection into a plain PHP array. If the collection's values are Eloquent models, the models will also be converted to arrays

$comments_collection = $post->comments()->get()->toArray()

From Laravel Docs:

toArray also converts all of the collection's nested objects that are an instance of Arrayable to an array. If you want to get the raw underlying array, use the all method instead.

Try to add the following line in ~/.bashrc

export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

1.Install-Package Microsoft.AspNet.WebApi.Cors

2 . Add this code in WebApiConfig.cs.

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services

    // Web API routes

    config.EnableCors();

    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
}

3. Add this

using System.Web.Http.Cors; 

4. Add this code in Api Controller (HomeController.cs)

[EnableCors(origins: "*", headers: "*", methods: "*")]
public class HomeController : ApiController
{
    [HttpGet]
    [Route("api/Home/test")]
    public string test()
    {
       return "";
    }
}

If you can use psutil, then this works perfectly:

import subprocess

import psutil


def kill(proc_pid):
    process = psutil.Process(proc_pid)
    for proc in process.children(recursive=True):
        proc.kill()
    process.kill()


proc = subprocess.Popen(["infinite_app", "param"], shell=True)
try:
    proc.wait(timeout=3)
except subprocess.TimeoutExpired:
    kill(proc.pid)

You should be able to convert your number to a Java Calendar, e.g.:

 Calendar.getInstance().setTimeInMillis(myDate);

From there, the comparison shouldn't be too hard.

In your table dbo.Sup_Item_Cat, it has a foreign key reference to another table. The way a FK works is it cannot have a value in that column that is not also in the primary key column of the referenced table.

If you have SQL Server Management Studio, open it up and sp_help 'dbo.Sup_Item_Cat'. See which column that FK is on, and which column of which table it references. You're inserting some bad data.

Let me know if you need anything explained better!

Json Pointer seem's to be getting growing support too.
