for angular 4, the working solution was to do inside the component

@HostListener('window:scroll', ['$event']) onScrollEvent($event){
  console.log($event);
  console.log("scrolling");
} 

This worked for me :

import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.format.annotation.DateTimeFormat.ISO;

@Column(name="end_date", nullable = false)
@DateTimeFormat(iso = ISO.DATE_TIME)
@JsonFormat(pattern = "yyyy-MM-dd HH:mm")
private LocalDateTime endDate;

Check Whether multidex enabled or not in your build.gradle(app level) under dependencies.if not place like below

dependecies{
multidexEnabled true
}

Check your gradle.properties(app level).if you see the below code

#org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

remove # before the line ,then it should be like this

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

1. The accepted answer is one way of fixing the issue, because it will just apply some strategy for the problematic dependency (com.google.code.findbugs:jsr305) and it will resolve the problem around the project, using some version of this dependency. Basically it will align the versions of this library inside the whole project.

2. There is an answer from @Santhosh (and couple of other people) who suggests to exclude the same dependency for espresso, which should work by the same way, but if the project has some other dependencies who depend on the same library (com.google.code.findbugs:jsr305), again we will have the same issue. So in order to use this approach you will need to exclude the same group from all project dependencies, who depend on com.google.code.findbugs:jsr305. I personally found that Espresso Contrib and Espresso Intents also use com.google.code.findbugs:jsr305.

I hope this thoughts will help somebody to realise what exactly is happening here and how things work (not just copy paste some code) :).

Access the field with array notation to avoid strict type checking on single field:

data['propertyName']; //will work even if data has not declared propertyName

Alternative way is (un)cast the variable for single access:

(<any>data).propertyName;//access propertyName like if data has no type

The first is shorter, the second is more explicit about type (un)casting

You can also totally disable type checking on all variable fields:

let untypedVariable:any= <any>{}; //disable type checking while declaring the variable
untypedVariable.propertyName = anyValue; //any field in untypedVariable is assignable and readable without type checking

Note: This would be more dangerous than avoid type checking just for a single field access, since all consecutive accesses on all fields are untyped

Copied from the stacktrace:

BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib has a constructor with a SessionFactory argument. By adding the @Autowired annotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactory in your case, and provide it as a constructor argument, e.g.

@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
    // ...
}

I found the it wonderful to cover multiple variants of date time format like this:

final DateTimeFormatterBuilder dtfb = new DateTimeFormatterBuilder();
dtfb.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSS"))
    .appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"))
    .appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SS"))
    .appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.S"))
    .parseDefaulting(ChronoField.HOUR_OF_DAY, 0)
    .parseDefaulting(ChronoField.MINUTE_OF_HOUR, 0)
    .parseDefaulting(ChronoField.SECOND_OF_MINUTE, 0);

I have had problems with @JodaStephen's implementation on JBoss EAP 6. So, I rewrote the conversion following Oracle's Java Tutorial in http://docs.oracle.com/javase/tutorial/datetime/iso/legacy.html.

    Date input = new Date();
    GregorianCalendar gregorianCalendar = (GregorianCalendar) Calendar.getInstance();
    gregorianCalendar.setTime(input);
    ZonedDateTime zonedDateTime = gregorianCalendar.toZonedDateTime();
    zonedDateTime.toLocalDate();

In the shell, you can't execute more than one statement at a time:

>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement

You need to execute them one by one:

>>> x = 5
>>> y = 6
>>>

When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

h5py provides a model of datasets and groups. The former is basically arrays and the latter you can think of as directories. Each is named. You should look at the documentation for the API and examples:

http://docs.h5py.org/en/latest/quick.html

A simple example where you are creating all of the data upfront and just want to save it to an hdf5 file would look something like:

In [1]: import numpy as np
In [2]: import h5py
In [3]: a = np.random.random(size=(100,20))
In [4]: h5f = h5py.File('data.h5', 'w')
In [5]: h5f.create_dataset('dataset_1', data=a)
Out[5]: <HDF5 dataset "dataset_1": shape (100, 20), type "<f8">

In [6]: h5f.close()

You can then load that data back in using: '

In [10]: h5f = h5py.File('data.h5','r')
In [11]: b = h5f['dataset_1'][:]
In [12]: h5f.close()

In [13]: np.allclose(a,b)
Out[13]: True

Definitely check out the docs:

http://docs.h5py.org

Writing to hdf5 file depends either on h5py or pytables (each has a different python API that sits on top of the hdf5 file specification). You should also take a look at other simple binary formats provided by numpy natively such as np.save, np.savez etc:

http://docs.scipy.org/doc/numpy/reference/routines.io.html

Maybe better document.querySelectorAll(".col1") because getElementsByClassName doesn't works in IE 8 and querySelectorAll does (althought CSS2 selectors only).

https://developer.mozilla.org/en-US/docs/Web/API/document.getElementsByClassName https://developer.mozilla.org/en-US/docs/Web/API/Document.querySelectorAll

Change:

x.length

to:

x.options.length

Link to fiddle

And I agree with Abraham - you might want to use text instead of value

Update
The reason your fiddle didn't work was because you chose the option: "onLoad" instead of: "No wrap - in "

The only thing the eclipse plugin is checking is the tomcat version inside:

catalina.jar!/org/apache/catalina/util/ServerInfo.properties

I replaced the properties file with the one in tomcat7 and that fixed the issue for eclipse

In order to be able to deploy the spring-websockets sample app you need to edit the following file in eclipse:

.settings/org.eclipse.wst.common.project.facet.core.xml

And change the web version to 2.5

<installed facet="jst.web" version="2.5"/>

How precise do you need to be? If you do need to take into account common years and leap years, and the exact difference in days between months then you'll have to write something more advanced but for a basic and rough calculation this should do the trick:

today = new Date()
past = new Date(2010,05,01) // remember this is equivalent to 06 01 2010
//dates in js are counted from 0, so 05 is june

function calcDate(date1,date2) {
    var diff = Math.floor(date1.getTime() - date2.getTime());
    var day = 1000 * 60 * 60 * 24;

    var days = Math.floor(diff/day);
    var months = Math.floor(days/31);
    var years = Math.floor(months/12);

    var message = date2.toDateString();
    message += " was "
    message += days + " days " 
    message += months + " months "
    message += years + " years ago \n"

    return message
    }


a = calcDate(today,past)
console.log(a) // returns Tue Jun 01 2010 was 1143 days 36 months 3 years ago

Keep in mind that this is imprecise, in order to calculate the date with full precision one would have to have a calendar and know if a year is a leap year or not, also the way I'm calculating the number of months is only approximate.

But you can improve it easily.

I think you have Two ways to solve this problem

01. Set Properties

• Set Java Build Path as jdk

Right click project ->Java Build Path ->Select Libraries tab ->Select JRE System Library ->Click Edit button ->Click Installed JREs-> add tick to box ->click Edit ->Click Directory->Select jdk

• Specifi which kind of jdk version you installed

Right click project ->Project Facets ->tick java and select java version->Apply ->Ok

• Update project

Right-click on "project"->Go to Maven->Update

02.Delete .m2 file

If you can't solve your problem using above two topic get this action Close your project. Delete your full .m2 folder

How to fined .m2 file(windows)

Go to Local Disk(C) ->Users ->Select your PC name ->.m2 file

Is there a way to get it via $event->getComposer()->getRepositoryManager()->getAllPackages()

If you are sending anything other than simple strings I would recommend using a POST with an appropriate request body, or passing the entire list as an appropriately encoded JSON string. However, with simple strings you just need to append each value to the request URL appropriately and Jersey will deserialize it for you. So given the following example endpoint:

@Path("/service/echo") public class MyServiceImpl {
    public MyServiceImpl() {
        super();
    }

    @GET
    @Path("/withlist")
    @Produces(MediaType.TEXT_PLAIN)
    public Response echoInputList(@QueryParam("list") final List<String> inputList) {
        return Response.ok(inputList).build();
    }
}

Your client would send a request corresponding to:

GET http://example.com/services/echo?list=Hello&list=Stay&list=Goodbye

Which would result in inputList being deserialized to contain the values 'Hello', 'Stay' and 'Goodbye'

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.

This is what i have been facing for long time.

This happened last time and figured out that one case could be a bad war deployment, which came after i update library/maven dependencies on pom and re installed it.

SOLUTION:

right click on the server >  remove the war and 
right click on the server again > clean
make sure the maven dependencies are added to deployment assembly
right click on the project > Run As > maven clean
right click on the project again > Run As > maven install 
and finally deploy the project on to the server. This helped me to solve the issue  

It looks like your Spring component scan Base is missing UserServiceImpl

<context:component-scan base-package="org.assessme.com.controller." />

Passing null would be better. The full codes is like:

WebView wv = (WebView)this.findViewById(R.id.myWebView);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL(null, "<html>...</html>", "text/html", "utf-8", null);

The problem you'll face is that there's two types of PEM formatted keys: PKCS8 and SSLeay. It doesn't help that OpenSSL seems to use both depending on the command:

The usual openssl genrsa command will generate a SSLeay format PEM. An export from an PKCS12 file with openssl pkcs12 -in file.p12 will create a PKCS8 file.

The latter PKCS8 format can be opened natively in Java using PKCS8EncodedKeySpec. SSLeay formatted keys, on the other hand, can not be opened natively.

To open SSLeay private keys, you can either use BouncyCastle provider as many have done before or Not-Yet-Commons-SSL have borrowed a minimal amount of necessary code from BouncyCastle to support parsing PKCS8 and SSLeay keys in PEM and DER format: http://juliusdavies.ca/commons-ssl/pkcs8.html. (I'm not sure if Not-Yet-Commons-SSL will be FIPS compliant)

Key Format Identification

By inference from the OpenSSL man pages, key headers for two formats are as follows:

PKCS8 Format

Non-encrypted: -----BEGIN PRIVATE KEY-----
Encrypted: -----BEGIN ENCRYPTED PRIVATE KEY-----

SSLeay Format

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

(These seem to be in contradiction to other answers but I've tested OpenSSL's output using PKCS8EncodedKeySpec. Only PKCS8 keys, showing ----BEGIN PRIVATE KEY----- work natively)

MDN: https://developer.mozilla.org/en/DOM/window.location

It seems that you will get the same result for both, but hostname contains clear host name without brackets or port number.

There's a short discussion of what appears to be this issue here. The page it links to appears to be gone, but one of the responses might be what you need:

Indeed, copying US_export_policy.jar and local_policy.jar from core/lib/jce to $JAVA_HOME/jre/lib/security helped. Thanks.

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

I use the IntelliJ one, because I'm mostly concerned with IntelliJ flagging things that might produce a NPE. I agree that it's frustrating not having a standard annotation in the JDK. There's talk of adding it, it might make it into Java 7. In which case there will be one more to choose from!

With @Resource you can do bean self-injection, it might be needed in order to run all extra logic added by bean post processors like transactional or security related stuff.

With Spring 4.3+ @Autowired is also capable of doing this.

This works and it is a lot easier to toggle that the methods above:

use inline: onended="if($(this).attr('data-loop')){ this.currentTime = 0; this.play(); }"

Turn the looping on by $(audio_element).attr('data-loop','1'); Turn the looping off by $(audio_element).removeAttr('data-loop');

javac HelloWorld.java -classpath ./javax.jar , assuming javax is in current folder, and compile target is "HelloWorld.java", and you can compile without a main method

I suggest you another possible solution. Perhaps less elegant, but easier!

public class MyBean {
  @Size(min=6, max=50)
  private String pass;

  private String passVerify;

  @AssertTrue(message="passVerify field should be equal than pass field")
  private boolean isValid() {
    return this.pass.equals(this.passVerify);
  }
}

The isValid method is invoked by the validator automatically.

The javax namespace is usually (that's a loaded word) used for standard extensions, currently known as optional packages. The standard extensions are a subset of the non-core APIs; the other segment of the non-core APIs obviously called the non-standard extensions, occupying the namespaces like com.sun.* or com.ibm.. The core APIs take up the java. namespace.

Not everything in the Java API world starts off in core, which is why extensions are usually born out of JSR requests. They are eventually promoted to core based on 'wise counsel'.

The interest in this nomenclature, came out of a faux pas on Sun's part - extensions could have been promoted to core, i.e. moved from javax.* to java.* breaking the backward compatibility promise. Programmers cried hoarse, and better sense prevailed. This is why, the Swing API although part of the core, continues to remain in the javax.* namespace. And that is also how packages get promoted from extensions to core - they are simply made available for download as part of the JDK and JRE.

@QueryParam documentation says

" The type T of the annotated parameter, field or property must either:

1) Be a primitive type
2) Have a constructor that accepts a single String argument
3) Have a static method named valueOf or fromString that accepts a single String argument (see, for example, Integer.valueOf(String))
4) Have a registered implementation of javax.ws.rs.ext.ParamConverterProvider JAX-RS extension SPI that returns a javax.ws.rs.ext.ParamConverter instance capable of a "from string" conversion for the type.
5) Be List, Set or SortedSet, where T satisfies 2, 3 or 4 above. The resulting collection is read-only. "

If you want to control what response goes to user when query parameter in String form can't be converted to your type T, you can throw WebApplicationException. Dropwizard comes with following *Param classes you can use for your needs.

BooleanParam, DateTimeParam, IntParam, LongParam, LocalDateParam, NonEmptyStringParam, UUIDParam. See https://github.com/dropwizard/dropwizard/tree/master/dropwizard-jersey/src/main/java/io/dropwizard/jersey/params

If you need Joda DateTime, just use Dropwizard DateTimeParam.

If the above list does not suit your needs, define your own by extending AbstractParam. Override parse method. If you need control over error response body, override error method.

Good article from Coda Hale on this is at http://codahale.com/what-makes-jersey-interesting-parameter-classes/

import io.dropwizard.jersey.params.AbstractParam;

import java.util.Date;

import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;

public class DateParam extends AbstractParam<Date> {

    public DateParam(String input) {
        super(input);
    }

    @Override
    protected Date parse(String input) throws Exception {
        return new Date(input);
    }

    @Override
    protected Response error(String input, Exception e) {
        // customize response body if you like here by specifying entity
        return Response.status(Status.BAD_REQUEST).build();
    }
}

Date(String arg) constructor is deprecated. I would use Java 8 date classes if you are on Java 8. Otherwise joda date time is recommended.

You can use the standard Java SE APIs:

private void updateCustomer(Customer customer) { 
    try { 
        URL url = new URL("http://www.example.com/customers"); 
        HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 
        connection.setDoOutput(true); 
        connection.setInstanceFollowRedirects(false); 
        connection.setRequestMethod("PUT"); 
        connection.setRequestProperty("Content-Type", "application/xml"); 

        OutputStream os = connection.getOutputStream(); 
        jaxbContext.createMarshaller().marshal(customer, os); 
        os.flush(); 

        connection.getResponseCode(); 
        connection.disconnect(); 
    } catch(Exception e) { 
        throw new RuntimeException(e); 
    } 
} 

Or you can use the REST client APIs provided by JAX-RS implementations such as Jersey. These APIs are easier to use, but require additional jars on your class path.

WebResource resource = client.resource("http://www.example.com/customers"); 
ClientResponse response = resource.type("application/xml");).put(ClientResponse.class, "<customer>...</customer."); 
System.out.println(response); 

For more information see:

• http://bdoughan.blogspot.com/2010/08/creating-restful-web-service-part-55.html

Converting your lists to sets will tell you that they contain the same elements. But this method cannot confirm that they contain the same number of all elements. For example, your method will fail in this case:

L1 = [1,2,2,3]
L2 = [1,2,3,3]

You are likely better off sorting the two lists and comparing them:

def checkEqual(L1, L2):
    if sorted(L1) == sorted(L2):
        print "the two lists are the same"
        return True
    else:
        print "the two lists are not the same"
        return False

Note that this does not alter the structure/contents of the two lists. Rather, the sorting creates two new lists

Date format class work with cheat code to make date. Like

1. M -> 7, MM -> 07, MMM -> Jul , MMMM -> July
2. EEE -> Tue , EEEE -> Tuesday
3. z -> EST , zzz -> EST , zzzz -> Eastern Standard Time

You can check more cheats here.

Overloading

Overloading is when you have multiple methods in the same scope, with the same name but different signatures.

//Overloading
public class test
{
    public void getStuff(int id)
    {}
    public void getStuff(string name)
    {}
}

Overriding

Overriding is a principle that allows you to change the functionality of a method in a child class.

//Overriding
public class test
{
        public virtual void getStuff(int id)
        {
            //Get stuff default location
        }
}

public class test2 : test
{
        public override void getStuff(int id)
        {
            //base.getStuff(id);
            //or - Get stuff new location
        }
}

Two solutions: 1- if the type of the target column is [nvarchar] it should be change to [varchar]

2- Add a "Derived Column" component to the SSIS package and add a new column with the following expression:
(DT_WSTR, «length») [ColumnName]

Length is the length of the column in the target table and ColumnName is the name of the column in the target table. finally at the mapping part you should use this new added column instead of the original column.

For me the following worked after I changed the directory of the namenode and datanode in hdfs-site.xml

-- before executing the following steps stop all services with stop-all.sh or in my case I used the stop-dfs.sh to stop the dfs

1. On the new configured directory, for every node (namenode and datanode), delete every folder/files inside it (in my case a 'current' directory).
2. delete the Hadoop temporary directory: $rm -rf /tmp/haddop-$USER
3. format the Namenode: hadoop/bin/hdfs namenode -format
4. start-dfs.sh

After I followed those steps my namenode and datanodes were alive using the new configured directory.

You can pass an object which is refering to all the values at a particular index.

import java.util.ArrayList;

public class HelloWorld{

 public static void main(String []args){


ArrayList<connect> a=new ArrayList<connect>();

a.add(new connect(100,100,100,100,100));

System.out.println(a.get(0).p1);

System.out.println(a.get(0).p2);

System.out.println(a.get(0).p3);
}

}

class connect
{
int p1,p2,p3,p4,p5;

connect(int a,int b,int c,int d,int e)
{

this.p1=a;

this.p2=b;

this.p3=c;

this.p4=d;

this.p5=e;
}

}

Later to get a particular value at a specific index, you can do this:

a.get(0).p1;

a.get(0).p2;

a.get(0).p3;.............

and so on.

Or if "NOT EXISTS" are not implemented

SELECT *
FROM   B
WHERE (SELECT count(*)  FROM   A WHERE  A.ID = B.ID) < 1

Try increasing your ram of intel HAXM by reinstalling it.. Worked for me.. In my pc HAXM setup's location was here: C-Users-Pc's_name-AppData-Local-Android-sdk-extras-intel-Hardware_Accelerated_Execution_Manager

Visual Basic has a nice function : ReDim Preserve.

Someone has kindly written an equivalent function - you can find it here. I think it does exactly what you are asking for (and you're not re-inventing the wheel - you're copying someone else's)...

• Upcasting is an operation that creates a base class reference from a subclass reference. (subclass -> superclass) (i.e. Manager -> Employee)
• Downcasting is an operation that creates a subclass reference from a base class reference. (superclass -> subclass) (i.e. Employee -> Manager)

In your case

Employee emp = (Employee)mgr; //mgr is Manager

you are doing an upcasting.

An upcast always succeeds unlike a downcast that requires an explicit cast because it can potentially fail at runtime.(InvalidCastException).

C# offers two operators to avoid this exception to be thrown:

Starting from:

Employee e = new Employee();

First:

Manager m = e as Manager; // if downcast fails m is null; no exception thrown

Second:

if (e is Manager){...} // the predicate is false if the downcast is not possible 

Warning: When you do an upcast you can only access to the superclass' methods, properties etc...

As explained in Python's super() considered super, one way is to have class eat the arguments it requires, and pass the rest on. Thus, when the call-chain reaches object, all arguments have been eaten, and object.__init__ will be called without arguments (as it expects). So your code should look like this:

class A(object):
    def __init__(self, *args, **kwargs):
        print "A"
        super(A, self).__init__(*args, **kwargs)

class B(object):
    def __init__(self, *args, **kwargs):
        print "B"
        super(B, self).__init__(*args, **kwargs)

class C(A):
    def __init__(self, arg, *args, **kwargs):
        print "C","arg=",arg
        super(C, self).__init__(*args, **kwargs)

class D(B):
    def __init__(self, arg, *args, **kwargs):
        print "D", "arg=",arg
        super(D, self).__init__(*args, **kwargs)

class E(C,D):
    def __init__(self, arg, *args, **kwargs):
        print "E", "arg=",arg
        super(E, self).__init__(*args, **kwargs)

print "MRO:", [x.__name__ for x in E.__mro__]
E(10, 20, 30)

I like ZenBurn theme, I think it is very mild and appealing for the eye. I had here my own theme's settings JAR file, but I stopped updating it. I still think that theme is very good so I updated this post to a suitable theme with similar colors which is already available on @Yarg's web site

If kill -9 isn't working, then neither will killall (or even killall -9 which would be more "intense"). Apparently the chromium process is stuck in a non-interruptible system call (i.e., in the kernel, not in userland) -- didn't think MacOSX had any of those left, but I guess there's always one more:-(. If that process has a controlling terminal you can probably background it and kill it while backgrounded; otherwise (or if the intense killing doesn't work even once the process is bakcgrounded) I'm out of ideas and I'm thinking you might have to reboot:-(.

For me a noop on table has been enough (was already InnoDB):

ALTER TABLE $tbl ENGINE=InnoDB;

$("a.save, #country") 

will select both "a.save" class and "country" id.

Apart from the methods mentioned earlier. You can also use the command del to remove multiple variables

del variable1,variable2

My solution to this issue was that my old laptop was taking wayyyyyyyyyyy too long to start up. I opened Virtual Box, connected to the box and waited for the screen to load. Took about 8 minutes.

Then it connected and mounted my folders and went ahead.

   1. In config/local.js
   2. In config/env/production.js

HTTP and WS handling

1. The app must run on HTTP in development so we can easily debug our app.
2. The app must run on HTTPS in production for security concern.
3. App production HTTP request should always redirect to https.

SSL configuration

In Sailsjs there are two ways to configure all the stuff, first is to configure in config folder with each one has their separate files (like database connection regarding settings lies within connections.js ). And second is configure on environment base file structure, each environment files presents in config/env folder and each file contains settings for particular env.

Sails first looks in config/env folder and then look forward to config/ *.js

Now lets setup ssl in config/local.js.

var local = {
   port: process.env.PORT || 1337,
   environment: process.env.NODE_ENV || 'development'
};

if (process.env.NODE_ENV == 'production') {
    local.ssl = {
        secureProtocol: 'SSLv23_method',
        secureOptions: require('constants').SSL_OP_NO_SSLv3,
        ca: require('fs').readFileSync(__dirname + '/path/to/ca.crt','ascii'),
        key: require('fs').readFileSync(__dirname + '/path/to/jsbot.key','ascii'),
        cert: require('fs').readFileSync(__dirname + '/path/to/jsbot.crt','ascii')
    };
    local.port = 443; // This port should be different than your default port
}

module.exports = local;

Alternative you can add this in config/env/production.js too. (This snippet also show how to handle multiple CARoot certi)

Or in production.js

module.exports = {
    port: 443,
    ssl: {
        secureProtocol: 'SSLv23_method',
        secureOptions: require('constants').SSL_OP_NO_SSLv3,
        ca: [
            require('fs').readFileSync(__dirname + '/path/to/AddTrustExternalCARoot.crt', 'ascii'),
            require('fs').readFileSync(__dirname + '/path/to/COMODORSAAddTrustCA.crt', 'ascii'),
            require('fs').readFileSync(__dirname + '/path/to/COMODORSADomainValidationSecureServerCA.crt', 'ascii')
        ],
        key: require('fs').readFileSync(__dirname + '/path/to/jsbot.key', 'ascii'),
        cert: require('fs').readFileSync(__dirname + '/path/to/jsbot.crt', 'ascii')
    }
};

http/https & ws/wss redirection

Here ws is Web Socket and wss represent Secure Web Socket, as we set up ssl then now http and ws both requests become secure and transform to https and wss respectively.

There are many source from our app will receive request like any blog post, social media post but our server runs only on https so when any request come from http it gives “This site can’t be reached” error in client browser. And we loss our website traffic. So we must redirect http request to https, same rules allow for websocket otherwise socket will fails.

So we need to run same server on port 80 (http), and divert all request to port 443(https). Sails first compile config/bootstrap.js file before lifting server. Here we can start our express server on port 80.

In config/bootstrap.js (Create http server and redirect all request to https)

module.exports.bootstrap = function(cb) {
    var express = require("express"),
        app = express();

    app.get('*', function(req, res) {  
        if (req.isSocket) 
            return res.redirect('wss://' + req.headers.host + req.url)  

        return res.redirect('https://' + req.headers.host + req.url)  
    }).listen(80);
    cb();
};

Now you can visit http://www.yourdomain.com, it will redirect to https://www.yourdomain.com

Don't even know how this whole thing works, but I tried ^\s*$ and didn't work (leaving still some empty lines).

This instead ^\s* works for me

{sublime text 3}

android:ems or setEms(n) sets the width of a TextView to fit a text of n 'M' letters regardless of the actual text extension and text size. See wikipedia Em unit

but only when the layout_width is set to "wrap_content". Other layout_width values override the ems width setting.

Adding an android:textSize attribute determines the physical width of the view to the textSize * length of a text of n 'M's set above.

if you have multiple parameters use the syntax as below. I have a bat file with script as below:

start "dummyTitle" [/options] D:\path\ProgramName.exe Param1 Param2 Param3 
start "dummyTitle" [/options] D:\path\ProgramName.exe Param4 Param5 Param6 

This will open multiple consoles.

HTML:

?<div class="header">This is the header</div>
<div class="content">This is the content</div>?????????????????????????????????

CSS:

?.header
{
    height:50px;
}
.content
{
    position:absolute;
    top: 50px;
    left:0px;
    right:0px;
    bottom:0px;
    overflow-y:scroll;        
}?

I quickly did this for anyone else coming onto this page:

<object width="425" height="344">

</object>

See the jsFiddle.

Below code will count Message from 0 to 137 each 0.3 second replacing previous number.

Number of symbol to backstage = number of digits.

stream = sys.stdout
for i in range(137):
    stream.write('\b' * (len(str(i)) + 10))
    stream.write("Message : " + str(i))
    stream.flush()
    time.sleep(0.3)

This works for me:

? brew link --overwrite macvim
Linking /usr/local/Cellar/macvim/8.0-146_1... 12 symlinks created

Try it

Thread.currentThread().getStackTrace()[1].getClassName()

Or

Thread.currentThread().getStackTrace()[2].getClassName()

Using sudo is not recommended. It may give you permission issue later. While the above works, I am not a fan of changing folders owned by root to be writable for users, although it may only be an issue with multiple users. To work around that, you could use a group, with 'npm users' but that is also more administrative overhead. See here for the options to deal with permissions from the documentation: https://docs.npmjs.com/getting-started/fixing-npm-permissions

I would go for option 2:

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.

Make a directory for global installations:

 mkdir ~/.npm-global

Configure npm to use the new directory path:

 npm config set prefix '~/.npm-global'

Open or create a ~/.profile file and add this line:

 export PATH=~/.npm-global/bin:$PATH

Back on the command line, update your system variables:

 source ~/.profile

Test: Download a package globally without using sudo.

npm install -g jshint

If still show permission error run (mac os):

sudo chown -R $USER ~/.npm-global   

This works with the default ubuntu install of:

sudo apt-get install nodejs npm

I recommend nvm if you want more flexibility in managing versions: https://github.com/creationix/nvm

On MacOS use brew, it should work without sudo out of the box if you're on a recent npm version. Enjoy :)

Yes. Please see the man page of bash ( the first thing you go to ) under Special Parameters

Special Parameters

The shell treats several parameters specially. These parameters may only be referenced; assignment to them is not allowed.

* Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

@ Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

I noticed that none of these answers mention the .Offset Property. This also can be used to avoid using the Select action when manipulating certain cells, particularly in reference to a selected cell (as the OP mentions with ActiveCell).

Here are a couple examples.

I will also assume the "ActiveCell" is J4.

ActiveCell.Offset(2, 0).Value = 12

• This will change the cell J6 to be a value of 12
• A minus -2 would have referenced J2

ActiveCell.Offset(0,1).Copy ActiveCell.Offset(,2)

• This will copy the cell in k4 to L4.
• Note that "0" is not needed in the offset parameter if not needed (,2)
• Similar to the previous example a minus 1 would be i4

ActiveCell.Offset(, -1).EntireColumn.ClearContents

• This will clear values in all cells in the column k.

These aren't to say they are "better" than the above options, but just listing alternatives.

I have tried these methods and find that they dont work for my needs. In my case, I needed to inject json rendered server side into the main template of the page, so when it loads and angular inits, the data is already there and doesnt have to be retrieved (large dataset).

The easiest solution that I have found is to do the following:

In your angular code outside of the app, module and controller definitions add in a global javascript value - this definition MUST come before the angular stuff is defined.

Example:

'use strict';

//my data variable that I need access to.
var data = null;

angular.module('sample', [])

Then in your controller:

.controller('SampleApp', function ($scope, $location) {

$scope.availableList = [];

$scope.init = function () {
    $scope.availableList = data;
}

Finally, you have to init everything (order matters):

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
  <script src="/path/to/your/angular/js/sample.js"></script>
  <script type="text/javascript">
      data = <?= json_encode($cproducts); ?>
  </script>

Finally initialize your controller and init function.

  <div ng-app="samplerrelations" ng-controller="SamplerApp" ng-init="init();">

By doing this you will now have access to whatever data you stuffed into the global variable.

In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.

So register the ChildComponent in Shared Module manually.

Here is a non-jQuery solution. Note you can't just use .click() as some browsers do not support it.

<script type="text/javascript">
function performClick(elemId) {
   var elem = document.getElementById(elemId);
   if(elem && document.createEvent) {
      var evt = document.createEvent("MouseEvents");
      evt.initEvent("click", true, false);
      elem.dispatchEvent(evt);
   }
}
</script>
<a href="#" onclick="performClick('theFile');">Open file dialog</a>
<input type="file" id="theFile" />

The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!

If you want to hide them anyway: error_reporting(0);

What Tyler Rinker says is correct:

AQ2 <- airquality
AQ2[is.na(AQ2)] <- 0

will do just this.

What you are originally doing is that you are taking from airquality all those rows (cases) that are complete. So, all the cases that do not have any NA's in them, and keep only those.

Find can be used to print out the file-size in bytes with %s as a printf. %h/%f prints the directory prefix and filename respectively. \n forces a newline.

Example

find . -size +10000k -printf "%h/%f,%s\n"

Output

./DOTT/extract/DOTT/TENTACLE.001,11358470

python setup.py install is used to install (typically third party) packages that you're not going to develop/modify/debug yourself.

For your own stuff, you want to first install your package and then be able to frequently edit the code without having to re-install the package every time — and that is exactly what python setup.py develop does: it installs the package (typically just a source folder) in a way that allows you to conveniently edit your code after it’s installed to the (virtual) environment, and have the changes take effect immediately.

Note that it is highly recommended to use pip install . (install) and pip install -e . (developer install) to install packages, as invoking setup.py directly will do the wrong things for many dependencies, such as pull prereleases and incompatible package versions, or make the package hard to uninstall with pip.

Use $$ if you want your math to appear in a single line, e.g.,

$$a = b + c$$ (line break after the equation)

If you don't need a line break after the math, use single dollar sign $, e.g.,

$a = b + c$   (no line break after the equation)

For date formatting the most easy way is using moment lib. https://momentjs.com/

const moment = require('moment')
const current = moment().utc().format('Y-M-D H:M:S')

Set the owner of the directory to the user running apache. Often nobody on linux

chown nobody:nobody <dirname>

This way your folder will not be world writable, but still writable for apache :)

Use implementation androidx.appcompat:appcompat:1.0.2 in gradle and then

change import android.support.annotation.Nullable; to import androidx.annotation.NonNull; in the classes imports

Run PowerShell or command prompt as Administrator and run below command.

dotnet tool install --global dotnet-ef --version 3.1.3

Try this:

import time

t_end = time.time() + 60 * 15
while time.time() < t_end:
    # do whatever you do

This will run for 15 min x 60 s = 900 seconds.

Function time.time returns the current time in seconds since 1st Jan 1970. The value is in floating point, so you can even use it with sub-second precision. In the beginning the value t_end is calculated to be "now" + 15 minutes. The loop will run until the current time exceeds this preset ending time.

With the latest .NET Framework, it is possible to return a value from a separate thread using a Task, where the Result property blocks the calling thread until the task finishes:

  Task<MyClass> task = Task<MyClass>.Factory.StartNew(() =>
  {
      string s = "my message";
      double d = 3.14159;
      return new MyClass { Name = s, Number = d };
  });
  MyClass test = task.Result;

str.replace(/^.+?\"|^.|\".+/, '');

This is sometimes bad to use when you wanna select what else to remove between "" and you cannot use it more than twice in one string. All it does is select whatever is not in between "" and replace it with nothing.

Even for me it is a bit confusing, but ill try to explain it. ^.+? (not anything OPTIONAL) till first " then | Or/stop (still researching what it really means) till/at ^. has selected nothing until before the 2nd " using (| stop/at). And select all that comes after with .+.

Add the configuration manager file to connect to the database web.config

It's your "fault" in that that's how Or is defined, so it's the behaviour you should expect:

In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.

But you don't have to endure it. You can use OrElse to get short-circuiting behaviour.

So you probably want:

If (example Is Nothing OrElse Not example.Item = compare.Item) Then
    'Proceed
End If

I can't say it reads terribly nicely, but it should work...

#!/usr/bin/perl -l

use strict;

# if string below commented out, prints 'lol' , if the string enabled, prints 'eeeeeeeee'
#my $lol = 'eeeeeeeeeee' ;
# no errors or warnings at any case, despite of 'strict'

our $lol = eval {$lol} || 'lol' ;

print $lol;

It is a good practice to .gitignore at least your build products (programs, *.o, etc.).

I wanted a splash screen that would display until the main program form was ready to be displayed, so timers etc were no use to me. I also wanted to keep it as simple as possible. My application starts with (abbreviated):

static void Main()
{
    Splash frmSplash = new Splash();
    frmSplash.Show();
    Application.Run(new ReportExplorer(frmSplash));
}

Then, ReportExplorer has the following:

public ReportExplorer(Splash frmSplash)
{
    this.frmSplash = frmSplash;
    InitializeComponent();
}

Finally, after all the initialisation is complete:

if (frmSplash != null) 
{
     frmSplash.Close();
     frmSplash = null;
}

Maybe I'm missing something, but this seems a lot easier than mucking about with threads and timers.

Try array_replace_recursive or array_replace functions

$a = array('userID' => 1, 'username'=> 2);

If the option -d works in your system, here's another way to do it. There is a caveat that it wouldn't account for leap years since I've considered 365 days per year.

date1yrs=`date -d "20100209" +%Y`
date1days=`date -d "20100209" +%j`
date2yrs=`date +%Y`
date2days=`date +%j`
diffyr=`expr $date2yrs - $date1yrs`
diffyr2days=`expr $diffyr \* 365`
diffdays=`expr $date2days - $date1days`
echo `expr $diffyr2days + $diffdays`

Try this solution if the Reset Password option (of SQL Developer) did not work:

Step 1: Open Run SQL Command Line (from the start menu, which comes with SQL Developer installation package)

Step 2: Run the following commands:

Note: If password has already expired, Changing password for <user> option will automatically come.

I found this was caused by adding a new scope variable to the login scope

compare properties in the array if one matches the input then set something to the value of the loops current position, which is also the index of the current looked up item.

simple eg.

dim x,y,z as integer
dim aNames, aIndexes as array
dim sFind as string
for x = 1 to length(aNames)

    if aNames(x) = sFind then y = x

y is then the index of the item in the array, then loop could be used to store these in an array also so instead of the above you would have:

z = 1
for x = 1 to length(aNames)
    if aNames(x) = sFind then 
        aIndexes(z) = x 
        z = z + 1
    endif

You will need some JavaScript to prevent cropping if you don't know the dimension of the image at the time you're writing the css.

HTML & JavaScript

<div id="container">
    <img src="something.jpg" alt="" />
</div>

<script type="text/javascript">
(function() {

var img = document.getElementById('container').firstChild;
img.onload = function() {
    if(img.height > img.width) {
        img.height = '100%';
        img.width = 'auto';
    }
};

}());
</script>

CSS

#container {
   width: 48px;
   height: 48px;
}

#container img {
   width: 100%;
}

If you use a JavaScript Library you might want to take advantage of it.

None of these answers seemed simple enough - the crux of the problem is not having to rebuild:

makefile

OBJDIR=out
VPATH=$(OBJDIR)

# make will look in VPATH to see if the target needs to be rebuilt
test: moo
    touch $(OBJDIR)/$@

example use

touch moo
# creates out/test
make test
# doesn't update out/test
make test
# will now update test
touch moo
make test

Use children() and each(), you can optionally pass a selector to children

$('#mydiv').children('input').each(function () {
    alert(this.value); // "this" is the current element in the loop
});

You could also just use the immediate child selector:

$('#mydiv > input').each(function () { /* ... */ });

The below method worked for me, Kudos to github user : midnightcodr

Make sure You remove any nodejs/npm packages already installed.

sudo apt-get purge nodejs

sudo apt-get purge npm

Now Install Node js using the command below( Thanks to midnightcodr on github)

curl -L https://raw.github.com/midnightcodr/rpi_node_install/master/setup.sh | bash -s 0.10.24

Note that you can invoke node with command node and not nodejs.

Once node is installed , Install npm

sudo apt-get install npm

Try just:

powershell.exe -noexit D:\Work\SQLExecutor.ps1 -gettedServerName "MY-PC"

You don't have to register an actual BroadcastReceiver as Android's BatteryManager is using a sticky Intent:

IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = registerReceiver(null, ifilter);

int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1);

float batteryPct = level / (float)scale;

return (int)(batteryPct*100);

This is from the official docs over at https://developer.android.com/training/monitoring-device-state/battery-monitoring.html.

It looks like IDEA solves this for you (like everything else). When loading a large project and letting it thrash, it will open a dialog to up the memory settings. Entering 2048 for Xmx and clicking "Shutdown", then restarting IDEA makes IDEA start up with more memory. This seems to work well for Mac OS, though it never seems to persist for me on Windows (not sure about IDEA 12).

On Windows, you can find it under.

%USERPROFILE%\AppData\Roaming\Subversion\auth\svn.simple
(same as below)
%APPDATA%\Roaming\Subversion\auth\svn.simple

There may be multiple files under this directory, depending upon the repos you are contributing to. You can assume this as one file for each svn server. You can open the file with any text editor and make sure you are going to delete the correct file.

just convert denominator to decimal before division e.g

select col1 / CONVERT(decimal(4,2), col2) from tbl1

It may be nicer one to use slice like :

string.slice(1, -1)

ncdu (ncurses du)

This awesome CLI utility allows you to easily find the large files and directories (recursive total size) interactively.

For example, from inside the root of a well known open source project we do:

sudo apt install ncdu
ncdu

The outcome its:

Then, I enter down and right on my keyboard to go into the /drivers folder, and I see:

ncdu only calculates file sizes recursively once at startup for the entire tree, so it is efficient.

"Total disk usage" vs "Apparent size" is analogous to du, and I have explained it at: why is the output of `du` often so different from `du -b`

Tested in Ubuntu 16.04.

Ubuntu list root

You likely want:

ncdu --exclude-kernfs -x /

where:

• -x stops crossing of filesystem barriers
• --exclude-kernfs skips special filesystems like /sys

MacOS 10.15.5 list root

To properly list root / on that system, I also needed --exclude-firmlinks, e.g.:

brew install ncdu
cd /
ncdu --exclude-firmlinks

otherwise it seemed to go into some link infinite loop, likely due to: https://www.swiftforensics.com/2019/10/macos-1015-volumes-firmlink-magic.html

The things we learn for love.

ncdu non-interactive usage

Another cool feature of ncdu is that you can first dump the sizes in a JSON format, and later reuse them.

For example, to generate the file run:

ncdu -o ncdu.json

and then examine it interactively with:

ncdu -f ncdu.json

This is very useful if you are dealing with a very large and slow filesystem like NFS.

This way, you can first export only once, which can take hours, and then explore the files, quit, explore again, etc.

The output format is just JSON, so it is easy to reuse it with other programs as well, e.g.:

ncdu -o -  | python -m json.tool | less

reveals a simple directory tree data structure:

Tested in Ubuntu 18.04.

Replying in particular to:

You can create a new interface in the networking panel, based on an existing interface, but it will not act as a real fully functional interface (if the original interface is inactive, then the derived one is also inactive).

This can be achieved using a Tun/Tap device as suggested by psv141, and manipulating the /Library/Preferences/SystemConfiguration/preferences.plist file to add a NetworkService based on either a tun or tap interface. Mac OS X will not allow the creation of a NetworkService based on a virtual network interface, but one can directly manipulate the preferences.plist file to add the NetworkService by hand. Basically you would open the preferences.plist file in Xcode (or edit the XML directly, but Xcode is likely to be more fool-proof), and copy the configuration from an existing Ethernet interface. The place to create the new NetworkService is under "NetworkServices", and if your Mac has an Ethernet device the NetworkService profile will also be under this property entry. The Ethernet entry can be copied pretty much verbatim, the only fields you would actually be changing are:

• UUID
• UserDefinedName
• IPv4 configuration and set the interface to your tun or tap device (i.e. tun0 or tap0).
• DNS server if needed.

Then you would also manipulate the particular Location you want this NetworkService for (remember Mac OS X can configure all network interfaces dependent on your "Location"). The default location UUID can be obtained in the root of the PropertyList as the key "CurrentSet". After figuring out which location (or set) you want, expand the Set property, and add entries under Global/IPv4/ServiceOrder with the UUID of the new NetworkService. Also under the Set property you need to expand the Service property and add the UUID here as a dictionary with one String entry with key __LINK__ and value as the UUID (use the other interfaces as an example).

After you have modified your preferences.plist file, just reboot, and the NetworkService will be available under SystemPreferences->Network. Note that we have mimicked an Ethernet device so Mac OS X layer of networking will note that "a cable is unplugged" and will not let you activate the interface through the GUI. However, since the underlying device is a tun/tap device and it has an IP address, the interface will become active and the proper routing will be added at the BSD level.

As a reference this is used to do special routing magic.

In case you got this far and are having trouble, you have to create the tun/tap device by opening one of the devices under /dev/. You can use any program to do this, but I'm a fan of good-old-fashioned C myself:

#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
int main()
{
   int fd = open("/dev/tun0", O_RDONLY);
   if (fd < 0)
   {
      printf("Failed to open tun/tap device. Are you root? Are the drivers installed?\n");
      return -1;
   }
   while (1)
   {
      sleep(100000);
   }
   return 0;
}

Thought I would chip in here with when I have found ON to be more useful than USING. It is when OUTER joins are introduced into queries.

ON benefits from allowing the results set of the table that a query is OUTER joining onto to be restricted while maintaining the OUTER join. Attempting to restrict the results set through specifying a WHERE clause will, effectively, change the OUTER join into an INNER join.

Granted this may be a relative corner case. Worth putting out there though.....

For example:

CREATE TABLE country (
   countryId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
   country varchar(50) not null,
  UNIQUE KEY countryUIdx1 (country)
) ENGINE=InnoDB;

insert into country(country) values ("France");
insert into country(country) values ("China");
insert into country(country) values ("USA");
insert into country(country) values ("Italy");
insert into country(country) values ("UK");
insert into country(country) values ("Monaco");


CREATE TABLE city (
  cityId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
  countryId int(10) unsigned not null,
  city varchar(50) not null,
  hasAirport boolean not null default true,
  UNIQUE KEY cityUIdx1 (countryId,city),
  CONSTRAINT city_country_fk1 FOREIGN KEY (countryId) REFERENCES country (countryId)
) ENGINE=InnoDB;


insert into city (countryId,city,hasAirport) values (1,"Paris",true);
insert into city (countryId,city,hasAirport) values (2,"Bejing",true);
insert into city (countryId,city,hasAirport) values (3,"New York",true);
insert into city (countryId,city,hasAirport) values (4,"Napoli",true);
insert into city (countryId,city,hasAirport) values (5,"Manchester",true);
insert into city (countryId,city,hasAirport) values (5,"Birmingham",false);
insert into city (countryId,city,hasAirport) values (3,"Cincinatti",false);
insert into city (countryId,city,hasAirport) values (6,"Monaco",false);

-- Gah. Left outer join is now effectively an inner join 
-- because of the where predicate
select *
from country left join city using (countryId)
where hasAirport
; 

-- Hooray! I can see Monaco again thanks to 
-- moving my predicate into the ON
select *
from country co left join city ci on (co.countryId=ci.countryId and ci.hasAirport)
; 

This may be overkill for a simple breadcrumb, but it's worth a shot. I remember having this issue a long time ago when I first started, but I never really solved it. That is, until I just decided to write this up now. :)

I have documented as best I can inline, at the bottom are 3 possible use cases. Enjoy! (feel free to ask any questions you may have)

<?php

// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' &raquo; ', $home = 'Home') {
    // This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));

    // This will build our "base URL" ... Also accounts for HTTPS :)
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';

    // Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
    $breadcrumbs = Array("<a href=\"$base\">$home</a>");

    // Find out the index for the last value in our path array
    $last = end(array_keys($path));

    // Build the rest of the breadcrumbs
    foreach ($path AS $x => $crumb) {
        // Our "title" is the text that will be displayed (strip out .php and turn '_' into a space)
        $title = ucwords(str_replace(Array('.php', '_'), Array('', ' '), $crumb));

        // If we are not on the last index, then display an <a> tag
        if ($x != $last)
            $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";
        // Otherwise, just display the title (minus)
        else
            $breadcrumbs[] = $title;
    }

    // Build our temporary array (pieces of bread) into one big string :)
    return implode($separator, $breadcrumbs);
}

?>

<p><?= breadcrumbs() ?></p>
<p><?= breadcrumbs(' > ') ?></p>
<p><?= breadcrumbs(' ^^ ', 'Index') ?></p>

You should install Android SDK Build Tools 23.0.1 via Android SDK. Don't forget to check Show Packages Details.

A strong reference (which you will use in most cases) means that you want to "own" the object you are referencing with this property/variable. The compiler will take care that any object that you assign to this property will not be destroyed as long as you point to it with a strong reference. Only once you set the property to nil will the object get destroyed (unless one or more other objects also hold a strong reference to it).

In contrast, with a weak reference you signify that you don't want to have control over the object's lifetime. The object you are referencing weakly only lives on because at least one other object holds a strong reference to it. Once that is no longer the case, the object gets destroyed and your weak property will automatically get set to nil. The most frequent use cases of weak references in iOS are:

1. delegate properties, which are often referenced weakly to avoid retain cycles, and

2. subviews/controls of a view controller's main view because those views are already strongly held by the main view.

atomic vs. nonatomic refers to the thread safety of the getter and setter methods that the compiler synthesizes for the property. atomic (the default) tells the compiler to make the accessor methods thread-safe (by adding a lock before an ivar is accessed) and nonatomic does the opposite. The advantage of nonatomic is slightly higher performance. On iOS, Apple uses nonatomic for almost all their properties so the general advice is for you to do the same.

Johnny's answer is great, but still didn't work for me just by adding those lines described there. Based on that answer, the steps that actually worked for me where:

1. Install WhiteNoise as described:

   pip install WhiteNoise
   

2. Create the STATIC_ROOT variable and add WhiteNoise to your MIDDLEWARE variable in settings.py:

   #settings.py
   MIDDLEWARE = [
       'django.middleware.security.SecurityMiddleware',
       'whitenoise.middleware.WhiteNoiseMiddleware', #add whitenoise
       'django.contrib.sessions.middleware.SessionMiddleware',
       ...
   ]
   
   #...
   
   STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') ##specify static root
   

3. Then, modify your wsgi.py file as explained in Johnny's answer:

   #wsgi.py
   from django.core.wsgi import get_wsgi_application
   from whitenoise.django import DjangoWhiteNoise
   
   application = get_wsgi_application()
   application = DjangoWhiteNoise(application)
   

4. After that, deploy your changes to your server (with git or whatever you use).

5. Finally, run the collectstatic option from your manage.py on your server. This will copy all files from your static folders into the STATIC_ROOT directory we specified before:

   $ python manage.py collectstatic
   

   You will now see a new folder named staticfiles that contains such elements.

After following these steps you can now run your server and will be able to see your static files while in Production mode.

Update: In case you had version < 4 the changelog indicates that it's no longer necessary to declare the WSGI_APPLICATION = 'projectName.wsgi.application' on your settings.py file.

You can use this command:

start /min iexplore http://www.google.com

With the use of /min, it will hit on the URL without opening in the browser.

function myFunction() {
  var sheetname = "DateEntry";//Sheet where you want to put the date
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetname);
    // You could use now Date(); on its own but it will not look nice.
  var date = Utilities.formatDate(new Date(), "GMT+5:30", "yyyy-MM-dd");
    //var endDate = date;
    sheet.getRange(sheet.getLastRow() + 1,1).setValue(date); //Gets the last row which had value, and goes to the next empty row to put new values.
}

My error occurred because, somehow, there was an obj folder created inside my controllers folder. Just do a search in your application for a line inside your Assemblyinfo.cs. There may be a duplicate somewhere.

' \r ' means carriage return.

The \r means nothing special as a consequence.For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller . Historically a \n was used to move the carriage down, while the \r was used to move the carriage back to the left side of the screen.

Check whether the particular port is open on the server to serve the client or not?

in Ubuntu or Linux distro

sudo ufw enable
sudo ufw allow 5000/tcp //allow the server to handle the request on port 5000

Configure the application to handle remote requests

app.run(host='0.0.0.0' , port=5000)


python3 app.py & #run application in background

Add width:100px, margin:50%. Now the left side of the button is set to the center.
Finally add half of the width of the button in our case 50px.
The middle of the button is in the center.

<input type='submit' style='width:100px;margin:0 50%;position:relative;left:-50px;'>

This is an old question, nevertheless the answers did not satisfy me regarding to performance and optimization.

Here my optimized C# variant (distance in km, without variables and redundant calculations, very close to mathematical expression of Haversine Formular https://en.wikipedia.org/wiki/Haversine_formula).

Inspired by: https://rosettacode.org/wiki/Haversine_formula#C.23

public static class Haversine
{
    public static double Calculate(double lat1, double lon1, double lat2, double lon2)
    {
        double rad(double angle) => angle * 0.017453292519943295769236907684886127d; // = angle * Math.Pi / 180.0d
        double havf(double diff) => Math.Pow(Math.Sin(rad(diff) / 2d), 2); // = sin²(diff / 2)
        return 12745.6 * Math.Asin(Math.Sqrt(havf(lat2 - lat1) + Math.Cos(rad(lat1)) * Math.Cos(rad(lat2)) * havf(lon2 - lon1))); // earth radius 6.372,8?km x 2 = 12745.6
    }
}

First, eq is for comparing strings; == is for comparing numbers.

Even if the "if" condition is satisfied, it doesn't evaluate the "then" block.

I think your problem is that your variables don't contain what you think they do. I think your $str1 or $str2 contains something like "taste\n" or so. Check them by printing before your if: print "str1='$str1'\n";.

The trailing newline can be removed with the chomp($str1); function.

Note that cp A B; rm A is exactly mv A B. It'll be faster too, as you don't have to actually copy the bytes (assuming the destination is on the same filesystem), just rename the file. So you want cp A B; mv A C

<a href="/index2.php?option=com_jumi&amp;fileid=3&amp;Itemid=11"
   onclick="window.open(this.href,'targetWindow',

                                    location=no,
                                    status=no,

 return false;">Popup link</a>

Where width and height are pixels without units (width=400 not width=400px).

In most browsers it will not work if it is not written without line breaks, once the variables are setup have everything in one line:

<a href="/index2.php?option=com_jumi&amp;fileid=3&amp;Itemid=11" onclick="window.open(this.href,'targetWindow','toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=SomeSize,height=SomeSize'); return false;">Popup link</a> 

Alpine uses the command adduser and addgroup for creating users and groups (rather than useradd and usergroup).

FROM alpine:latest

# Create a group and user
RUN addgroup -S appgroup && adduser -S appuser -G appgroup

# Tell docker that all future commands should run as the appuser user
USER appuser

The flags for adduser are:

Usage: adduser [OPTIONS] USER [GROUP]

Create new user, or add USER to GROUP

        -h DIR          Home directory
        -g GECOS        GECOS field
        -s SHELL        Login shell
        -G GRP          Group
        -S              Create a system user
        -D              Don't assign a password
        -H              Don't create home directory
        -u UID          User id
        -k SKEL         Skeleton directory (/etc/skel)

Probably this is not best code for this task, but is working -

def front_back(a, b):

 if len(a) % 2 == 0 and len(b) % 2 == 0:
    print a[:(len(a)/2)] + b[:(len(b)/2)] + a[(len(a)/2):] + b[(len(b)/2):]

 elif len(a) % 2 == 1 and len(b) % 2 == 0:
    print a[:(len(a)/2)+1] + b[:(len(b)/2)] + a[(len(a)/2)+1:] + b[(len(b)/2):] 

 elif len(a) % 2 == 0 and len(b) % 2 == 1:
     print a[:(len(a)/2)] + b[:(len(b)/2)+1] + a[(len(a)/2):] + b[(len(b)/2)+1:] 

 else :
     print a[:(len(a)/2)+1] + b[:(len(b)/2)+1] + a[(len(a)/2)+1:] + b[(len(b)/2)+1:]

In case of Allow IP to mysql server linux machine. you can do following command--

 nano /etc/httpd/conf.d/phpMyAdmin.conf  and add Desired IP.

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8
   Order allow,deny
   allow from all
   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>

    Require ip 192.168.9.1(Desired IP)

</RequireAny>
   </IfModule>
 <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     #Allow from All

     Allow from 192.168.9.1(Desired IP)

</IfModule>

And after Update, please restart using following command--

sudo systemctl restart httpd.service

# detach head and move to D commit
git checkout <SHA1-for-D>

# move HEAD to A, but leave the index and working tree as for D
git reset --soft <SHA1-for-A>

# Redo the D commit re-using the commit message, but now on top of A
git commit -C <SHA1-for-D>

# Re-apply everything from the old D onwards onto this new place 
git rebase --onto HEAD <SHA1-for-D> master

From a practical standpoint, every table--even a denormalized table like a warehouse table--should have a primary key. Or, failing that, it should at least have a unique, non-nullable index.

Without some kind of unique key, duplicate records can (and will) appear in the table, which is very problematic both for ORM layers and also for basic comprehension of the data. A table that has duplicate records is probably a symptom of bad design.

At the very least, the table should at least have an identity column. Adding an auto-generating ID column takes about 2 minutes in SQL Server and 5 minutes in Oracle. For that extra bit of effort, many, many problems will be avoided.

Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.

 server {
            listen       80;
            server_name  localhost;

            access_log  logs/localhost.access.log  main;

            location / {
                root /var/www/board/public;
                index index.html index.htm index.php;
            }
       }

You can configure setup.exe to skip this check using the parameters below -

setup.exe -ignorePrereq -ignorePrereq -J"-Doracle.install.db.validate.supportedOSCheck=false"

After zach I would also recommend boto, but I needed to make a slight difference to his code:

conn = boto.connect_s3('access-key', 'secret'key')
bucket = conn.lookup('bucket-name')
for key in bucket:
    print key.name

USE MyDatabase
SELECT Count(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE';

to get table counts

SELECT COUNT(*)
FROM information_schema.tables
WHERE table_schema = 'dbName';

this also works

USE databasename;
SHOW TABLES;
SELECT FOUND_ROWS();

Change it to the following:

$ci = get_instance();
$ci->load->library('email');
$config['protocol'] = "smtp";
$config['smtp_host'] = "ssl://smtp.gmail.com";
$config['smtp_port'] = "465";
$config['smtp_user'] = "[email protected]"; 
$config['smtp_pass'] = "yourpassword";
$config['charset'] = "utf-8";
$config['mailtype'] = "html";
$config['newline'] = "\r\n";

$ci->email->initialize($config);

$ci->email->from('[email protected]', 'Blabla');
$list = array('[email protected]');
$ci->email->to($list);
$this->email->reply_to('[email protected]', 'Explendid Videos');
$ci->email->subject('This is an email test');
$ci->email->message('It is working. Great!');
$ci->email->send();

One way is to stack the frames on top of each other, then you can simply raise one above the other in the stacking order. The one on top will be the one that is visible. This works best if all the frames are the same size, but with a little work you can get it to work with any sized frames.

Note: for this to work, all of the widgets for a page must have that page (ie: self) or a descendant as a parent (or master, depending on the terminology you prefer).

Here's a bit of a contrived example to show you the general concept:

try:
    import tkinter as tk                # python 3
    from tkinter import font as tkfont  # python 3
except ImportError:
    import Tkinter as tk     # python 2
    import tkFont as tkfont  # python 2

class SampleApp(tk.Tk):

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)

        self.title_font = tkfont.Font(family='Helvetica', size=18, weight="bold", slant="italic")

        # the container is where we'll stack a bunch of frames
        # on top of each other, then the one we want visible
        # will be raised above the others
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}
        for F in (StartPage, PageOne, PageTwo):
            page_name = F.__name__
            frame = F(parent=container, controller=self)
            self.frames[page_name] = frame

            # put all of the pages in the same location;
            # the one on the top of the stacking order
            # will be the one that is visible.
            frame.grid(row=0, column=0, sticky="nsew")

        self.show_frame("StartPage")

    def show_frame(self, page_name):
        '''Show a frame for the given page name'''
        frame = self.frames[page_name]
        frame.tkraise()


class StartPage(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(self, text="This is the start page", font=controller.title_font)
        label.pack(side="top", fill="x", pady=10)

        button1 = tk.Button(self, text="Go to Page One",
                            command=lambda: controller.show_frame("PageOne"))
        button2 = tk.Button(self, text="Go to Page Two",
                            command=lambda: controller.show_frame("PageTwo"))
        button1.pack()
        button2.pack()


class PageOne(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(self, text="This is page 1", font=controller.title_font)
        label.pack(side="top", fill="x", pady=10)
        button = tk.Button(self, text="Go to the start page",
                           command=lambda: controller.show_frame("StartPage"))
        button.pack()


class PageTwo(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(self, text="This is page 2", font=controller.title_font)
        label.pack(side="top", fill="x", pady=10)
        button = tk.Button(self, text="Go to the start page",
                           command=lambda: controller.show_frame("StartPage"))
        button.pack()


if __name__ == "__main__":
    app = SampleApp()
    app.mainloop()

If you find the concept of creating instance in a class confusing, or if different pages need different arguments during construction, you can explicitly call each class separately. The loop serves mainly to illustrate the point that each class is identical.

For example, to create the classes individually you can remove the loop (for F in (StartPage, ...) with this:

self.frames["StartPage"] = StartPage(parent=container, controller=self)
self.frames["PageOne"] = PageOne(parent=container, controller=self)

It is possible but, before git 2.9.3 (august 2016), a git push would print the full url used when pushing back to the cloned repo.
That would include your username and password!

But no more: See commit 68f3c07 (20 Jul 2016), and commit 882d49c (14 Jul 2016) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 71076e1, 08 Aug 2016)}

push: anonymize URL in status output

Commit 47abd85 (fetch: Strip usernames from url's before storing them, 2009-04-17, Git 1.6.4) taught fetch to anonymize URLs.
The primary purpose there was to avoid sticking passwords in merge-commit messages, but as a side effect, we also avoid printing them to stderr.

The push side does not have the merge-commit problem, but it probably should avoid printing them to stderr. We can reuse the same anonymizing function.

Note that for this to come up, the credentials would have to appear either on the command line or in a git config file, neither of which is particularly secure.
So people should be switching to using credential helpers instead, which makes this problem go away.

But that's no excuse not to improve the situation for people who for whatever reason end up using credentials embedded in the URL.

Image by default is displayed as inline-block, you need to display it as block in order to center it with .mx-auto. This can be done with built-in .d-block:

<div class="container">
    <div class="row">
        <div class="col-4">
            <img class="mx-auto d-block" src="...">  
        </div>
    </div>
</div>

Or leave it as inline-block and wrapped it in a div with .text-center:

<div class="container">
    <div class="row">
        <div class="col-4">
          <div class="text-center">
            <img src="..."> 
          </div>     
        </div>
    </div>
</div>

I made a fiddle showing both ways. They are documented here as well.

SQL Server actually stores time as fractions of a day. For example, 1 whole day = value of 1. 12 hours is a value of 0.5.

If you want to store the time value without utilizing a DATETIME type, storing the time in a decimal form would suit that need, while also making conversion to a DATETIME simple.

For example:

SELECT CAST(0.5 AS DATETIME)
--1900-01-01 12:00:00.000

Storing the value as a DECIMAL(9,9) would consume 5 bytes. However, if precision to not of utmost importance, a REAL would consume only 4 bytes. In either case, aggregate calculation (i.e. mean time) can be easily calculated on numeric values, but not on Data/Time types.

To add to this, I've been doing a diagram application, and initially started out with canvas. The diagram consists of many nodes, and they can get quite big. The user can drag elements in the diagram around.

What I found was that on my Mac, for very large images, SVG is superior. I have a MacBook Pro 2013 13" Retina, and it runs the fiddle below quite well. The image is 6000x6000 pixels, and has 1000 objects. A similar construction in canvas was impossible to animate for me when the user was dragging objects around in the diagram.

On modern displays you also have to account for different resolutions, and here SVG gives you all of this for free.

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

There is much simpler way:

using System;
using System.Collections.Generic;
....
var caseInsensitiveDictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

I used to have the same problem finding a good library to do that. Eventually, I created a library which can do that: SwipeRevealLayout

In gradle file:

dependencies {
    compile 'com.chauthai.swipereveallayout:swipe-reveal-layout:1.4.0'
}

In your xml file:

<com.chauthai.swipereveallayout.SwipeRevealLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:mode="same_level"
    app:dragEdge="left">

    <!-- Your secondary layout here -->
    <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent" />

    <!-- Your main layout here -->
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</com.chauthai.swipereveallayout.SwipeRevealLayout>

Then in your adapter file:

public class Adapter extends RecyclerView.Adapter {
  // This object helps you save/restore the open/close state of each view
  private final ViewBinderHelper viewBinderHelper = new ViewBinderHelper();

  @Override
  public void onBindViewHolder(ViewHolder holder, int position) {
    // get your data object first.
    YourDataObject dataObject = mDataSet.get(position); 

    // Save/restore the open/close state.
    // You need to provide a String id which uniquely defines the data object.
    viewBinderHelper.bind(holder.swipeRevealLayout, dataObject.getId()); 

    // do your regular binding stuff here
  }
}

The main difference between return false and event.preventDefault() is that your code below return false will not be executed and in event.preventDefault() case your code will execute after this statement.

When you write return false it do the following things for you behind the scenes.

* Stops callback execution and returns immediately when called.
* event.stopPropagation();
* event.preventDefault();

Another solution is

class T1
{
    enum
    {
        t = 100
    };

    public:
    T1();
};

So t is initialised to 100 and it cannot be changed and it is private.

You can try this

<dependencies>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>3.1.0.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>

An easy way to print the sorted contents of the dictionary, in Python 3:

>>> dict_example = {'c': 1, 'b': 2, 'a': 3}
>>> for key, value in sorted(dict_example.items()):
...   print("{} : {}".format(key, value))
... 
a : 3
b : 2
c : 1

The expression dict_example.items() returns tuples, which can then be sorted by sorted():

>>> dict_example.items()
dict_items([('c', 1), ('b', 2), ('a', 3)])
>>> sorted(dict_example.items())
[('a', 3), ('b', 2), ('c', 1)]

Below is an example to pretty print the sorted contents of a Python dictionary's values.

for key, value in sorted(dict_example.items(), key=lambda d_values: d_values[1]): 
    print("{} : {}".format(key, value))

Try this code it works:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim CustomeDate As String = ("#" & DOE.Value.Date.ToString("d/MM/yyyy") & "#")
    MsgBox(CustomeDate.ToString)

    con.Open()

    dadap = New System.Data.OleDb.OleDbDataAdapter("SELECT * FROM QRY_Tran where FORMAT(qry_tran.doe,'d/mm/yyyy') = " & CustomeDate & "", con)

    ds = New System.Data.DataSet
    dadap.Fill(ds)
    Dgview.DataSource = ds.Tables(0)
    con.Close()

Note : if u use dd for date representation it will return nothing while selecting 1 to 9 so use d for selection

'Date time format
'MMM     Three-letter month.
'ddd     Three-letter day of the week.
'd       Day of the month.
'HH      Two-digit hours on 24-hour scale.
'mm      Two-digit minutes.
'yyyy    Four-digit year.

The documentation contains a full list of the date formats.

Another thing to try is

Tools -> Options -> search for IIS -> tick Use the 64 bit version of IIS Express for web sites and projects.

Do you really need an object? What about:

$myArray[] = array("name" => "my name");

Just use a two-dimensional array.

Output (var_dump):

array(1) {
  [0]=>
  array(1) {
    ["name"]=>
    string(7) "my name"
  }
}

You could access your last entry like this:

echo $myArray[count($myArray) - 1]["name"];

type() ?

>>> class A:
...     def whoami(self):
...         print(type(self).__name__)
...
>>>
>>> class B(A):
...     pass
...
>>>
>>>
>>> o = B()
>>> o.whoami()
'B'
>>>

This creates backup files. E.g. sed -i -e 's/hello/hello world/' testfile for me, creates a backup file, testfile-e, in the same dir.

I used a ternary in this case to keep track of the index backwards:

function palindromeCheck(string) {
  let str = string.toLowerCase();
  let palindrome;
   for (let i = 0; i < str.length; i++) {
    if (str[i] === str[str.length - (i == 0 ? 1 : i + 1)]) {
    palindrome = true;
    } else {
      palindrome = false;
   }
}

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

It seems like you are essentially looking into computing the z-score or standard score of your data, which is calculated through the formula: z = (x-mean(x))/std(x)

This should work:

%% Original data (Normal with mean 1 and standard deviation 2)
x = 1 + 2*randn(100,1);
mean(x)
var(x)
std(x)

%% Normalized data with mean 0 and variance 1
z = (x-mean(x))/std(x);
mean(z)
var(z)
std(z)

Oops. Original answer was specific to a similar question. This has been revised:

var canvas = document.getElementById("mycanvas");
var img    = canvas.toDataURL("image/png");

with the value in IMG you can write it out as a new Image like so:

document.write('<img src="'+img+'"/>');

Solution with actual 90% calculation:

@Override public void onStart() {
   Dialog dialog = getDialog();
   if (dialog != null) {
     dialog.getWindow()
        .setLayout((int) (getScreenWidth(getActivity()) * .9), ViewGroup.LayoutParams.MATCH_PARENT);
   }
}

where getScreenWidth(Activity activity) is defined the following (best put in a Utils class):

public static int getScreenWidth(Activity activity) {
   Point size = new Point();
   activity.getWindowManager().getDefaultDisplay().getSize(size);
   return size.x;
}

Look at your function s definition. If you forget using "()" after function declaration somewhere, you ll get plenty of errors with the same format:

 ... ??: class, interface, or enum expected ...

And also you have forgot closing bracket after your class or function definition ends. But note that these missing bracket, is not the only reason for this type of error.

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

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

            onclick=false;
            }
        }
    });

came across the same prob and found no straight solution to it on the forums etc. Finally the following solution worked perfectly for me: simply implement the following logic inside your event handler function for the form 'submit' Event:

document.getElementById('myForm').addEventListener('submit', handlerToTheSubmitEvent);

function handlerToTheSubmitEvent(e){
    //DO NOT use e.preventDefault();
   
    /*
    your form validation logic goes here
    */

    if(allInputsValidatedSuccessfully()){
         return true;
     }
     else{
         return false; 
     }
}

SIMPLE AS THAT; NOTE: when a 'false' is returned from the handler of the form 'submit' event, the form is not submitted to the URI specified in the action attribute of your html markup; until and unless a 'true' is returned by the handler; and as soon as all your input fields are validated a 'true' will be returned by the Event handler, and your form is gonna be submitted;

ALSO NOTE THAT: the function call inside the if() condition is basically your own implementation of ensuring that all the fields are validated and consequently a 'true' must be returned from there otherwise 'false'

try this

UITextField *field = [[UITextField alloc] initWithFrame:CGRectMake(20, 80, 280, 120)];

Well, PHP json_encode() returns a string.

You can use parseFloat() or parseInt() in the js code though:

parseFloat('122.5'); // returns 122.5
parseInt('22'); // returns 22
parseInt('22.5'); // returns 22

I am not very good in grep. But your problem can be solved using AWK command. Just see

awk '/select/,/from/' *.sql

The above code will result from first occurence of select till first sequence of from. Now you need to verify whether returned statements are having customername or not. For this you can pipe the result. And can use awk or grep again.

Same like "Jayantha" said using css would be the easiest approach, but this might be better,

.ui-autocomplete { max-height: 200px; overflow-y: scroll; overflow-x: hidden;}

Note the only difference is "max-height". this will allow the widget to resize to smaller height but not more than 200px

The accepted answer shows the reason for the deprecation but misses to name the alternative:

CellType    getCellTypeEnum()

where the CellType is the enum decribing the type of the cell.

The plan is to rename getCellTypeEnum() back to getCellType() in POI 4.0.

I say "star-args" and Python people seem to know what i mean.

** is trickier - I think just "qargs" since it is usually used as **kw or **kwargs

Compiling other answers:

Object

var test = {};

When using a number as a new property's key, the number turns into a string:

test[2300] = 'Some string';
console.log(test['2300']);
// Output: 'Some string'

When accessing the property's value using the same number, the number is turned into a string again:

console.log(test[2300]);
// Output: 'Some string'

When getting the keys from the object, though, they aren't going to be turned back into numbers:

for (var key in test) {
    console.log(typeof key);
}
// Output: 'string'

Map

ECMAScript 6 allows the use of the Map object (documentation, a comparison with Object). If your code is meant to be interpreted locally or the ECMAScript 6 compatibility table looks green enough for your purposes, consider using a Map:

var test = new Map();
test.set(2300, 'Some string');
console.log(test.get(2300));
// Output: 'Some string'

No type conversion is performed, for better and for worse:

console.log(test.get('2300'));
// Output: undefined
test.set('2300', 'Very different string');
console.log(test.get(2300));
// Output: 'Some string'

The following example was adapted from Mozilla Hacks' blog post and is using MutationObserver.

// Select the node that will be observed for mutations
var targetNode = document.getElementById('some-id');

// Options for the observer (which mutations to observe)
var config = { attributes: true, childList: true };

// Callback function to execute when mutations are observed
var callback = function(mutationsList) {
    for(var mutation of mutationsList) {
        if (mutation.type == 'childList') {
            console.log('A child node has been added or removed.');
        }
        else if (mutation.type == 'attributes') {
            console.log('The ' + mutation.attributeName + ' attribute was modified.');
        }
    }
};

// Create an observer instance linked to the callback function
var observer = new MutationObserver(callback);

// Start observing the target node for configured mutations
observer.observe(targetNode, config);

// Later, you can stop observing
observer.disconnect();

var product = {'name':'test'};
JSON.stringify(product);

Calling erase will invalidate iterators, you could use:

void erase(std::vector<int>& myNumbers_in, int number_in)
{
    std::vector<int>::iterator iter = myNumbers_in.begin();
    while (iter != myNumbers_in.end())
    {
        if (*iter == number_in)
        {
            iter = myNumbers_in.erase(iter);
        }
        else
        {
           ++iter;
        }
    }

}

Or you could use std::remove_if together with a functor and std::vector::erase:

struct Eraser
{
    Eraser(int number_in) : number_in(number_in) {}
    int number_in;
    bool operator()(int i) const
    {
        return i == number_in;
    }
};

std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), Eraser(number_in)), myNumbers.end());

Instead of writing your own functor in this case you could use std::remove:

std::vector<int> myNumbers;
myNumbers.erase(std::remove(myNumbers.begin(), myNumbers.end(), number_in), myNumbers.end());

In C++11 you could use a lambda instead of a functor:

std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), [number_in](int number){ return number == number_in; }), myNumbers.end());

In C++17 std::experimental::erase and std::experimental::erase_if are also available, in C++20 these are (finally) renamed to std::erase and std::erase_if (note: in Visual Studio 2019 you'll need to change your C++ language version to the latest experimental version for support):

std::vector<int> myNumbers;
std::erase_if(myNumbers, Eraser(number_in)); // or use lambda

or:

std::vector<int> myNumbers;
std::erase(myNumbers, number_in);

If you have an html form containing one or more fields with "required" attributes, Chrome (on last versions) will validate these fields before submitting the form and, if they are not filled, some tooltips will be shown to the users to help them getting the form submitted (I.e. "please fill out this field").

To avoid this browser built-in validation in forms you can use "novalidate" attribute on your form tag. This form won't be validated by browser:

<form id="form-id" novalidate>

    <input id="input-id" type="text" required>

    <input id="submit-button" type="submit">

</form>

From the github page:

A Python module to access Java classes as Python classes using JNI.

PyJNIus is a "Work In Progress".

Quick overview

>>> from jnius import autoclass
>>> autoclass('java.lang.System').out.println('Hello world') Hello world

>>> Stack = autoclass('java.util.Stack')
>>> stack = Stack()
>>> stack.push('hello')
>>> stack.push('world')
>>> print stack.pop() world
>>> print stack.pop() hello

I guess you're talking about C#. If so, you can try this

    ArrayList CompareArrayList(ArrayList a, ArrayList b)
    {
        ArrayList output = new ArrayList();
        for (int i = 0; i < a.Count; i++)
        {
            string str = (string)a[i];
            if (!b.Contains(str))
            {
                if(!output.Contains(str)) // check for dupes
                    output.Add(str);
            }
        }
        return output;
    }

To follow the example given here, but to clarify syntax with the use of header files, the function forward declaration contains the optional parameter default value.

myfile.h

void myfunc(int blah, int mode = 0);

myfile.cpp

void myfunc(int blah, int mode) /* mode = 0 */
{
    if (mode == 0)
        do_something();
     else
        do_something_else();
}

Create a file called mongod.cfg in MongoDB folder if you dont have it. In my case: C:\Users\ivanbtrujillo\MongoDB

Then, edit mongod.cfg with notepad and add a line with the following (our custom dbpath):

dbpath=C:\Users\ivanbtrujillo\MongoDB\data\db

In this file you should especify the logpath too. My mongod.cfg file is:

logpath=C:\Users\ivanbtrujillo\MongoDB\log\mongo.log
dbpath=C:\Users\ivanbtrujillo\MongoDB\data\db

If you uses mongoDB as a windows service, you have to change this key and especify the mongod.cfg file.

To install mongodb as a windows service run this command:

**"C:\Users\ivanbtrujillo\MongoDB\bin\mongod.exe" --config "C:\Users\ivanbtrujillo\MongoDB\mongod.cfg" –install**

Open regedit.exe and go to the following route:

HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\services\MongoDB

MongoDB service does not work, we have to edit the ImagePath key, delete its content and put the following:

**"C:\Users\ivanbtrujillo\MongoDB\bin\mongod.exe" --config "C:\Users\ivanbtrujillo\MongoDB\mongod.cfg" 
--logpath="C:\Users\ivanbtrujillo\MongoDB\log\mongo.log" –service**

We indicates to mongo it's config file and its logpath.

Then when you init the mongodb service, it works.

Here is a full tutorial to install mongoDB in windows: http://ivanbtrujillo.herokuapp.com/2014/07/24/installing-mongodb-as-a-service-windows/

Hope it helps,

Based on @brettdj's answer using a VBScript regex ojbect with two modifications:

• The function handles variants and returns a variant. That is, to take care of a null case; and
• Uses explicit object creation, with a reference to the "Microsoft VBScript Regular Expressions 5.5" library

Function GetDigitsInVariant(inputVariant As Variant) As Variant
  ' Returns:
  '     Only the digits found in a varaint.
  ' Examples:
  '     GetDigitsInVariant(Null) => Null
  '     GetDigitsInVariant("") => ""
  '     GetDigitsInVariant(2021-/05-May/-18, Tue) => 20210518
  '     GetDigitsInVariant(2021-05-18) => 20210518
  ' Notes:
  '     If the inputVariant is null, null will be returned.
  '     If the inputVariant is "", "" will be returned.
  ' Usage:
  '     VBA IDE Menu > Tools > References ...
  '       > "Microsoft VBScript Regular Expressions 5.5" > [OK]

  ' With an explicit object reference to RegExp we can get intellisense
  ' and review the object heirarchy with the object browser
  ' (VBA IDE Menu > View > Object Browser).
  Dim regex As VBScript_RegExp_55.RegExp
  Set regex = New VBScript_RegExp_55.RegExp
  
  Dim result As Variant
  result = Null
  
  If IsNull(inputVariant) Then
    result = Null
    
  Else
    With regex
      .Global = True
      .Pattern = "[^\d]+"
      result = .Replace(inputVariant, vbNullString)
    End With
  End If
  
  GetDigitsInVariant = result
End Function

Testing:

Private Sub TestGetDigitsInVariant()
  Dim dateVariants As Variant
  dateVariants = Array(Null, "", "2021-/05-May/-18, Tue", _
          "2021-05-18", "18/05/2021", "3434 ..,sdf,sfd 444")
  
  Dim dateVariant As Variant
  For Each dateVariant In dateVariants
    Debug.Print dateVariant & ": ", , GetDigitsInVariant(dateVariant)
  Next dateVariant
  Debug.Print
End Sub

mongod --configsvr --smallfiles --nojournal --dbpath cfg/1 --port 26052 --fork --logpath cfg/3.log >/dev/null

Create a single mongos server on the default port

sleep 2000
mongos --configdb ${HOSTNAME}:26050,${HOSTNAME}:26051,${HOSTNAME}:26052 --fork --logpath mongos.log >/dev/null

Sleep for some time before starting the mongos you will not face the problem

I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.

Try this (see a working example of this code in jsfiddle: http://jsfiddle.net/periklis/7ATLS/1/)

<input type = "button" id = "clickme" value="Click me!"/>
<div id = "alert_placeholder"></div>
<script>
bootstrap_alert = function() {}
bootstrap_alert.warning = function(message) {
            $('#alert_placeholder').html('<div class="alert"><a class="close" data-dismiss="alert">×</a><span>'+message+'</span></div>')
        }

$('#clickme').on('click', function() {
            bootstrap_alert.warning('Your text goes here');
});
</script>?

EDIT: There are now libraries that simplify and streamline this process, such as bootbox.js

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.

If you don't want word wrap, assign the CSS style white-space: nowrap to the cells.

I've faced same problem and came across to this thread but my problem was with upstream. Below git command worked for me.

Syntax

git checkout {remoteName}/{branch} -- {../path/file.js}

Example

git checkout upstream/develop -- public/js/index.js

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

This doesn't necessarily touch on OOP capabilities but in our last set of interviews we used a selection of buggy code from the Bug of the Month list. Watching the candidates find the bugs shows their analytical capabilities, shows the know how to interpret somebody elses code

If you have multiple elements with same id or same name, just assign same class to those multiple elements and access them by index & perform your required operation.

  <div>
        <span id="a" class="demo">1</span>
        <span id="a" class="demo">2</span>
        <span>3</span>
    </div>

JQ:

$($(".demo")[0]).val("First span");
$($(".demo")[1]).val("Second span");

I fixed a similar error by adding the json dataType like so:

$.ajax({
    type: "POST",
    url: "someUrl",
    dataType: "json",
    data: {
        varname1 : "varvalue1",
        varname2 : "varvalue2"
    },
    success: function (data) {
        $.each(data, function (varname, varvalue){
            ...
        });  
    }
});

And in my controller I had to use double quotes around any strings like so (note: they have to be escaped in java):

@RequestMapping(value = "/someUrl", method=RequestMethod.POST)
@ResponseBody
public String getJsonData(@RequestBody String parameters) {
    // parameters = varname1=varvalue1&varname2=varvalue2
    String exampleData = "{\"somename1\":\"somevalue1\",\"somename2\":\"somevalue2\"}";
    return exampleData;
}

So, you could try using double quotes around your numbers if they are being used as strings (and remove that last comma):

[{"id":"50","name":"SEO"},{"id":"22","name":"LPO"}]

How about:

    For Each oSheet In ActiveWorkbook.Sheets
        If oSheet.ListObjects.Count > 0 Then
          oCmbBox.AddItem oSheet.Name
        End If
    Next oSheet

Doing this directly via NumPy will be the most efficient:

df1['e'] = np.random.randn(sLength)

Note my original (very old) suggestion was to use map (which is much slower):

df1['e'] = df1['a'].map(lambda x: np.random.random())

The thing with your method is that you clutter your HTML with javascript. If you put your javascript in an external file you can access your HTML unobtrusive and this is much neater.

Lateron you can expand your code with addEventListener/attackEvent(IE) to prevent memory leaks.

This is without jQuery

<a href="123.com" id="elementid">link</a>

window.onload = function () {
  var el = document.getElementById('elementid');
  el.onclick = function (e) {
    var ev = e || window.event;
    // here u can use this or el as the HTML node
  }
}

You say you want to manipulate it with jQuery. So you can use jQuery. Than it is even better to do it like this:

// this is the window.onload startup of your JS as in my previous example. The difference is 
// that you can add multiple onload functions
$(function () {
  $('a#elementid').bind('click', function (e) {
    // "this" points to the <a> element
    // "e" points to the event object
  });
});

Eclipse >> project explorer >> servers >> server.xml >> tag >> remove duplicate tag of your project

In order to make more concise you can declare constructor parameters as public which automatically create properties with same names and these properties are available via this:

export class Environment {

  constructor(public id:number, public name:string) {}

  getProperties() {
    return `${this.id} : ${this.name}`;
  }
}

let serverEnv = new Environment(80, 'port');
console.log(serverEnv);

 ---result---
// Environment { id: 80, name: 'port' }

Looks like everyone is answering One-to-many vs. Many-to-many:

The difference between One-to-many, Many-to-one and Many-to-Many is:

One-to-many vs Many-to-one is a matter of perspective. Unidirectional vs Bidirectional will not affect the mapping but will make difference on how you can access your data.

• In Many-to-one the many side will keep reference of the one side. A good example is "A State has Cities". In this case State is the one side and City is the many side. There will be a column state_id in the table cities.

In unidirectional, Person class will have List<Skill> skills but Skill will not have Person person. In bidirectional, both properties are added and it allows you to access a Person given a skill( i.e. skill.person).

• In One-to-Many the one side will be our point of reference. For example, "A User has Addresses". In this case we might have three columns address_1_id, address_2_id and address_3_id or a look up table with multi column unique constraint on user_id on address_id.

In unidirectional, a User will have Address address. Bidirectional will have an additional List<User> users in the Address class.

• In Many-to-Many members of each party can hold reference to arbitrary number of members of the other party. To achieve this a look up table is used. Example for this is the relationship between doctors and patients. A doctor can have many patients and vice versa.

Sure, here is an example (standard HTML boilerplate omitted):

<svg id="svg1" xmlns="http://www.w3.org/2000/svg" style="width: 3.5in; height: 1in">_x000D_
  <circle id="circle1" r="30" cx="34" cy="34" _x000D_
            style="fill: red; stroke: blue; stroke-width: 2"/>_x000D_
  </svg>_x000D_
<button onclick="circle1.style.fill='yellow';">Click to change to yellow</button>

iOS 8 and later. Swift 2.0 and later:

override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    cell.separatorInset = UIEdgeInsetsZero
    if #available(iOS 8.0, *) {
        cell.layoutMargins = UIEdgeInsetsZero
    } else {
        // Fallback on earlier versions
    }
}

You could calculate the determinant of the matrix which is recursive and then form the adjoined matrix

Here is a short tutorial

I think this only works for square matrices

Another way of computing these involves gram-schmidt orthogonalization and then transposing the matrix, the transpose of an orthogonalized matrix is its inverse!

To remote server

mysqldump mydbname | ssh host2 "mysql mydbcopy"

To local server

mysqldump mydbname | mysql mydbcopy

export a=$(script.sh)

Hope this helps. Note there are no spaces between variable and =. To echo the output

echo $a

Sublime CodeFormatter has formatting support for PHP, JavaScript/JSON/JSONP, HTML, CSS, Python. Although I haven't used CodeFormatter for very long, I have been impressed with it's JS, HTML, and CSS "beautifying" capabilities. I haven't tried using it with PHP (I don't do any PHP development) or Python (which I have no experience with) but both languages have many options in the .sublime-settings file.

One note however, the settings aren't very easy to find. On Windows you will need to go to your %AppData%\Roaming\Sublime Text #\Packages\CodeFormatter\CodeFormatter.sublime-settings. As I don't have a Mac I'm not sure where the settings file is on OS X.

As for a shortcut key, I added this key binding to my "Key Bindings - User" file:

{
    "keys": ["ctrl+k", "ctrl+d"],
    "command": "code_formatter"
}

I use Ctrl + K, Ctrl + D because that's what Visual Studio uses for formatting. You can change it, of course, just remember that what you choose might conflict with some other feature's keyboard shortcut.

Update:

It seems as if the developers of Sublime Text CodeFormatter have made it easier to access the .sublime-settings file. If you install CodeFormatter with the Package Control plugin, you can access the settings via the Preferences -> Package Settings -> CodeFormatter -> Settings - Default and override those settings using the Preferences -> Package Settings -> CodeFormatter -> Settings - User menu item.

somehow and sometimes "terminfo" folder comes corrupted after a fresh installation. i don't know why, but the problem can be solved in this way:

1. Download Lion Installer from the App Store
2. Download unpkg: http://www.macupdate.com/app/mac/16357/unpkg
3. Open Lion Installer app in Finder (Right click -> Show Package
Contents)
4. Open InstallESD.dmg (under SharedSupport)
5. Unpack BSD.pkg with unpkg (Located under Packages)   Term info
will be located in the new BSD folder in /usr/share/terminfo

hope it helps.

GroupBox is better.But not only group box, even you can use Panels (System.Windows.Forms.Panel).

• That is very usefully when you are designing Internet Protocol version 4 setting dialog.(Check it with your pc(windows),then you can understand the behavior)

In addition to cemkalyoncu's solution:

next record:

SELECT * FROM foo WHERE id > 4 ORDER BY id LIMIT 1;

previous record:

SELECT * FROM foo WHERE id < 4 ORDER BY id DESC LIMIT 1;

edit: Since this answer has been getting a few upvotes lately, I really want to stress the comment I made earlier about understanding that a primary key colum is not meant as a column to sort by, because MySQL does not guarantee that higher, auto incremented, values are necessarily added at a later time.

If you don't care about this, and simply need the record with a higher (or lower) id then this will suffice. Just don't use this as a means to determine whether a record is actually added later (or earlier). In stead, consider using a datetime column to sort by, for instance.

Using Stopwatch and formatting elapsed time:

Function FormatElapsedTime($ts) 
{
    $elapsedTime = ""

    if ( $ts.Minutes -gt 0 )
    {
        $elapsedTime = [string]::Format( "{0:00} min. {1:00}.{2:00} sec.", $ts.Minutes, $ts.Seconds, $ts.Milliseconds / 10 );
    }
    else
    {
        $elapsedTime = [string]::Format( "{0:00}.{1:00} sec.", $ts.Seconds, $ts.Milliseconds / 10 );
    }

    if ($ts.Hours -eq 0 -and $ts.Minutes -eq 0 -and $ts.Seconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0:00} ms.", $ts.Milliseconds);
    }

    if ($ts.Milliseconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0} ms", $ts.TotalMilliseconds);
    }

    return $elapsedTime
}

Function StepTimeBlock($step, $block) 
{
    Write-Host "`r`n*****"
    Write-Host $step
    Write-Host "`r`n*****"

    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $time = $sw.Elapsed

    $formatTime = FormatElapsedTime $time
    Write-Host "`r`n`t=====> $step took $formatTime"
}

Usage Samples

StepTimeBlock ("Publish {0} Reports" -f $Script:ArrayReportsList.Count)  { 
    $Script:ArrayReportsList | % { Publish-Report $WebServiceSSRSRDL $_ $CarpetaReports $CarpetaDataSources $Script:datasourceReport };
}

StepTimeBlock ("My Process")  {  .\do_something.ps1 }

O.K. I neither have rep to comment on previous answer (of Philippe De Muyter) nor raise it's score, hence a new example using his define for SIGNED_MAX trivially extended for unsigned types:

// We can use it to define limits based on actual compiler built-in types also: 
#define INT_MAX   SIGNED_MAX(int)
// based on the above, we can extend it for unsigned types also:
#define UNSIGNED_MAX(x) (  (SIGNED_MAX(x)<<1) | 1 ) // We reuse SIGNED_MAX
#define UINT_MAX  UNSIGNED_MAX(unsigned int) // on ARM: 4294967295
// then we can have:
unsigned int width = UINT_MAX;

Unlike using this or that header, here we use the real type from the compiler.

A use case for it when you want to use a table with *ngIf and *ngFor - As putting a div in td/th will make the table element misbehave -. I faced this problem and that was the answer.

Rails 4.1 added Hash#compact and Hash#compact! as a core extensions to Ruby's Hash class. You can use them like this:

hash = { a: true, b: false, c: nil }
hash.compact                        
# => { a: true, b: false }
hash                                
# => { a: true, b: false, c: nil }
hash.compact!                        
# => { a: true, b: false }
hash                                
# => { a: true, b: false }
{ c: nil }.compact                  
# => {}

Heads up: this implementation is not recursive. As a curiosity, they implemented it using #select instead of #delete_if for performance reasons. See here for the benchmark.

In case you want to backport it to your Rails 3 app:

# config/initializers/rails4_backports.rb

class Hash
  # as implemented in Rails 4
  # File activesupport/lib/active_support/core_ext/hash/compact.rb, line 8
  def compact
    self.select { |_, value| !value.nil? }
  end
end

From what I understand from the W3C classifications is that <table>s are meant for displaying data 'only'.

Based on that I found it a lot easier to create a <div> with the backgrounds and all that and have a table with data floating over it using position: absolute; and background: transparent;...

It works on Chrome, Internet Explorer (6 and later) and Mozilla Firefox (2 and later).

Margins are used (or meant anyways) to create a spacer between container elements, like <table>, <div> and <form>, not <tr>, <td>, <span> or <input>. Using it for anything other than container elements will keep you busy adjusting your website for future browser updates.

You can also use package plyr, which is somehow more versatile:

library(plyr)

ddply(d, .(Name), summarize,  Rate1=mean(Rate1), Rate2=mean(Rate2))

  Name    Rate1    Rate2
1 Aira 16.33333 47.00000
2  Ben 31.33333 50.33333
3  Cat 44.66667 54.00000

One way to do this is using a shared service.

However I find the following solution much simpler, it allows to share data between 2 siblings.(I tested this only on Angular 5)

In you parent component template:

<!-- Assigns "AppSibling1Component" instance to variable "data" -->
<app-sibling1 #data></app-sibling1>
<!-- Passes the variable "data" to AppSibling2Component instance -->
<app-sibling2 [data]="data"></app-sibling2> 

app-sibling2.component.ts

import { AppSibling1Component } from '../app-sibling1/app-sibling1.component';
...

export class AppSibling2Component {
   ...
   @Input() data: AppSibling1Component;
   ...
}

Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards.

Although, this is indicated as an error your logs will be saved normally. The highlighted error will still be present until there is a fix of this bug. More about this in the m2e support site.

The current available solution is to use an external maven version rather than the bundled version of Eclipse. You can find about this solution and more details regarding this bug in the question below which i believe describes the same problem you are facing.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error

download your desired version of php binary from http://windows.php.net/download/ website. download Thread Safe binary zip version. Unzip the downloaded version of the PHP in a separate folder. Please make sure that your new php folder name is not "PHP". May be you can use filder name as the version name. For example for php 5.4 you can use php54.

Copy the new php folder into your xampp folder. Now go to yourxampp/apache/conf/extra folder. Open file httpd-xampp.conf from the folder extra. Change the following variables:

Variable PHPINIDir to be / Varaible LoadModule to be //php5apache2_2.dl

Save the file httpd-xampp.conf. Restart your XAMPP apache server. If your server get restarted successfully then your server php version is upgraded.

I think the best solution I have come across is on this stackoverflow. This short jQuery code allows all your hover effects to show on click or touch..
No need to add anything within the function.

$('body').on('touchstart', function() {});

Hope this helps.

Try creating a script like ~/sshv.sh that will show you what ssh is up to:

#!/bin/bash
ssh -vvv "$@"

Allow execution of the ~/sshv.sh file for the owner of the file:

chmod u+x ~/sshv.sh

Then invoke your git push with:

GIT_SSH=~/sshv.sh git push ...

In my case, this helped me figure out that I was using ssh shared connections that needed to be closed, so I killed those ssh processes and it started working.

I would just use table and not the form. Its done by using margin.

table {
  margin: 0 auto;
}

also try using something like

table td {
    padding-bottom: 5px;
}

instead of <br />

and also your input should end with /> e.g:

<input type="password" name="cpwd" />

This example should help? Along with the comments, of course >:)

WARNING: MAN IS AN OVERUSED FREQUENT WORD IN THIS PARAGRAPH/POST

Overall I recommend using the Scanner class since you can input large sentences, I'm not entirely sure System.in.read has such aspects. If possible, please correct me.

public class InputApp {

// Don't worry, passing in args in the main method as one of the arguments isn't required MAN

    public static void main(String[] argumentalManWithAManDisorder){
        char inputManAger;

        System.out.println("Input Some Crap Man: ");
        try{
            // If you forget to cast char you will FAIL YOUR TASK MAN
            inputManAger = (char) System.in.read();
            System.out.print("You entererd " + inputManAger + " MAN");
        }
        catch(Exception e){
            System.out.println("ELEMENTARY SCHOOL MAN");
        }
    }
}

I know there isn't any need to add a plugin for this.

But this can be useful if you are doing so many things with numbers. So checkout this plugin at least for a knowledge point of view.

The rest of karim79's answer is super cool.

Example of using a stored procedure with multiple out parameters

As User Mr. Brownstone suggested you can use a stored procedure; to make it easy for all i created a minimalist example. First create a stored procedure:

Create PROCEDURE MultipleOutParameter
    @Input int,
    @Out1 int OUTPUT, 
    @Out2 int OUTPUT 
AS
BEGIN
    Select @Out1 = @Input + 1
    Select @Out2 = @Input + 2   
    Select 'this returns your normal Select-Statement' as Foo
          , 'amazing is it not?' as Bar

    -- Return can be used to get even more (afaik only int) values 
    Return(@Out1+@Out2+@Input)
END 

Calling the stored procedure

To execute the stored procedure a few local variables are needed to receive the value:

DECLARE @GetReturnResult int, @GetOut1 int, @GetOut2 int 
EXEC @GetReturnResult = MultipleOutParameter  
    @Input = 1,
    @Out1 = @GetOut1 OUTPUT,
    @Out2 = @GetOut2 OUTPUT

To see the values content you can do the following

Select @GetReturnResult as ReturnResult, @GetOut1 as Out_1, @GetOut2 as Out_2 

This will be the result:

I have different approach if you want access token and make call to other resource system with access token in header

Spring Security comes with automatic security: oauth2 properties access from application.yml file for every request and every request has SESSIONID which it reads and pull user info via Principal, so you need to make sure inject Principal in OAuthUser and get accessToken and make call to resource server

This is your application.yml, change according to your auth server:

security:
  oauth2:
    client:
      clientId: 233668646673605
      clientSecret: 33b17e044ee6a4fa383f46ec6e28ea1d
      accessTokenUri: https://graph.facebook.com/oauth/access_token
      userAuthorizationUri: https://www.facebook.com/dialog/oauth

      authenticationScheme: query

Try This

   SELECT DISTINCT so.name
    FROM syscomments sc
    INNER JOIN sysobjects so ON sc.id=so.id
    WHERE sc.TEXT LIKE '%your table name%'

To be clearer (as i read this thread but didn't SEE the solution, also if it was here!), I have the same problem and found the cause: I were modifying the wrong php.ini!

Yes, there are 2 php.ini files in MAMP:

1. Applications/MAMP/conf/php5.5.10/php.ini
2. Applications/MAMP/bin/php/php5.5.10/conf/php.ini

The right php.ini file is the second: Applications/MAMP/bin/php/php5.5.10/conf/php.ini

To prove this, create a .php file (call it as you like, for example "info.php") and put into it a simple phpinfo()

<?php
echo phpinfo();

Open it in your browser and search for "Loaded Configuration File": mine is "/Applications/MAMP/bin/php/php5.5.10/conf/php.ini"

The error was here; i edited Applications/MAMP/conf/php5.5.10/php.ini but this is the wrong file to modify! Infact, the right php.ini file is the one in the bin directory.

Take care of this so small difference that caused me literally 1 and a half hours of headaches!

The view controller must be a child of some UINavigationController for the .title property to take effect. If the UINavigationBar is simply a view, you need to push a navigation item containing the title, or modify the last navigation item:

UINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@"title text"];
...
[bar pushNavigationItem:item animated:YES];
[item release];

or

bar.topItem.title = @"title text";

Add reference to COM "Active DS Type Library"

            Int32 nameTypeNT4               = (int) ActiveDs.ADS_NAME_TYPE_ENUM.ADS_NAME_TYPE_NT4;
            Int32 nameTypeDN                = (int) ActiveDs.ADS_NAME_TYPE_ENUM.ADS_NAME_TYPE_1779;
            Int32 nameTypeUserPrincipalName = (int) ActiveDs.ADS_NAME_TYPE_ENUM.ADS_NAME_TYPE_USER_PRINCIPAL_NAME;

            ActiveDs.NameTranslate nameTranslate = new ActiveDs.NameTranslate();

            // Convert NT name DOMAIN\User into AD distinguished name 
            // "CN= User\\, Name,OU=IT,OU=All Users,DC=Company,DC=com"
            nameTranslate.Set(nameTypeNT4, ntUser);

            String distinguishedName = nameTranslate.Get(nameTypeDN);

            Console.WriteLine(distinguishedName);

            // Convert AD distinguished name "CN= User\\, Name,OU=IT,OU=All Users,DC=Company,DC=com" 
            // into NT name DOMAIN\User
            ntUser = String.Empty;
            nameTranslate.Set(nameTypeDN, distinguishedName);
            ntUser = nameTranslate.Get(nameTypeNT4);
            Console.WriteLine(ntUser);

            // Convert NT name DOMAIN\User into AD UserPrincipalName [email protected]
            nameTranslate.Set(nameTypeNT4, ntUser);
            String userPrincipalName = nameTranslate.Get(nameTypeUserPrincipalName);

            Console.WriteLine(userPrincipalName);

Your code concatenates three strings, then converts the result to a number.

You need to convert each variable to a number by calling parseFloat() around each one.

total = parseFloat(myInt1) + parseFloat(myInt2) + parseFloat(myInt3);

You can use the following

import { find } from 'lodash'

Then to return the entire object (not only its key or value) from the list with the following:

let match = find(savedViews, { 'ID': 'id to match'});

SQLite doesn't support removing or modifying columns, apparently. But do remember that column data types aren't rigid in SQLite, either.

See also:

• SQLite Modify Column

To find the next element with the same class:

$(".class").eq( $(".class").index( $(element) ) + 1 )

var myObject = {"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"};_x000D_
    _x000D_
delete myObject.regex;_x000D_
_x000D_
console.log ( myObject.regex); // logs: undefined

This works in Firefox and Internet Explorer, and I think it works in all others.

The correct syntax for adding column into table is:

ALTER TABLE table_name
  ADD column_name column-definition;

In your case it will be:

ALTER TABLE Employees
  ADD EmployeeID int NOT NULL IDENTITY (1, 1)

To add multiple columns use brackets:

ALTER TABLE table_name
  ADD (column_1 column-definition,
       column_2 column-definition,
       ...
       column_n column_definition);

COLUMN keyword in SQL SERVER is used only for altering:

ALTER TABLE table_name
  ALTER COLUMN column_name column_type;

Yes you can use any client as long as it is supported by socket.io. No matter whether its node, java, android or swift. All you have to do is install the client package of socket.io.

Look at the documentation page.

Tweaking an existing Firefox profile

You need to change "network.proxy.http" & "network.proxy.http_port" profile settings.

FirefoxProfile profile = new FirefoxProfile();
profile.addAdditionalPreference("network.proxy.http", "localhost");
profile.addAdditionalPreference("network.proxy.http_port", "3128");
WebDriver driver = new FirefoxDriver(profile);

You can't really do it the C way (I think) but a pythonic way of doing this would be (if your 'inputs' have spaces in between them):

raw_answer = raw_input()
answers = raw_answer.split(' ') # list of 'answers'

So you could rewrite your try to:

var1, var2 = raw_input("enter two numbers:").split(' ')

Note that this it somewhat less flexible than using the 'first' solution (for example if you add a space at the end this will already break).

Also be aware that var1 and var2 will still be strings with this method when not cast to int.

I had to find a quick solution, so I just used a TextBox with those properties:

var myLabel = new TextBox
                    {
                        Text = "xxx xxx xxx",
                        WordWrap = true,
                        AutoSize = false,
                        Enabled = false,
                        Size = new Size(60, 30),
                        BorderStyle = BorderStyle.None,
                        Multiline =  true,
                        BackColor =  container.BackColor
                    };

Amazon DynamoDB provides the Scan operation for this purpose, which returns one or more items and its attributes by performing a full scan of a table. Please be aware of the following two constraints:

• Depending on your table size, you may need to use pagination to retrieve the entire result set:

  Note
  If the total number of scanned items exceeds the 1MB limit, the scan stops and results are returned to the user with a LastEvaluatedKey to continue the scan in a subsequent operation. The results also include the number of items exceeding the limit. A scan can result in no table data meeting the filter criteria.

  The result set is eventually consistent.

• The Scan operation is potentially costly regarding both performance and consumed capacity units (i.e. price), see section Scan and Query Performance in Query and Scan in Amazon DynamoDB:

  [...] Also, as a table grows, the scan operation slows. The scan operation examines every item for the requested values, and can use up the provisioned throughput for a large table in a single operation. For quicker response times, design your tables in a way that can use the Query, Get, or BatchGetItem APIs, instead. Or, design your application to use scan operations in a way that minimizes the impact on your table's request rate. For more information, see Provisioned Throughput Guidelines in Amazon DynamoDB. [emphasis mine]

You can find more details about this operation and some example snippets in Scanning Tables Using the AWS SDK for PHP Low-Level API for Amazon DynamoDB, with the most simple example illustrating the operation being:

$dynamodb = new AmazonDynamoDB();

$scan_response = $dynamodb->scan(array(
    'TableName' => 'ProductCatalog' 
));

foreach ($scan_response->body->Items as $item)
{
    echo "<p><strong>Item Number:</strong>"
         . (string) $item->Id->{AmazonDynamoDB::TYPE_NUMBER};
    echo "<br><strong>Item Name: </strong>"
         . (string) $item->Title->{AmazonDynamoDB::TYPE_STRING} ."</p>";
}

There are two ways to handle CGI scripts, SetHandler and AddHandler.

SetHandler cgi-script

applies to all files in a given context, no matter how they are named, even index.html or style.css.

AddHandler cgi-script .pl

is similar, but applies to files ending in .pl, in a given context. You may choose another extension or several, if you like.

Additionally, the CGI module must be loaded and Options +ExecCGI configured. To activate the module, issue

a2enmod cgi

and restart or reload Apache. Finally, the Perl CGI script must be executable. So the execute bits must be set

chmod a+x script.pl

and it should start with

#! /usr/bin/perl

as its first line.

When you use SetHandler or AddHandler (and Options +ExecCGI) outside of any directive, it is applied globally to all files. But you may restrict the context to a subset by enclosing these directives inside, e.g. Directory

<Directory /path/to/some/cgi-dir>
    SetHandler cgi-script
    Options +ExecCGI
</Directory>

Now SetHandler applies only to the files inside /path/to/some/cgi-dir instead of all files of the web site. Same is with AddHandler inside a Directory or Location directive, of course. It then applies to the files inside /path/to/some/cgi-dir, ending in .pl.

Sometimes the space after <?php visible if you are using the same editor, in my case I was using TextWrapper. Due to the file type configuration in the TextWrapper (in your case some other editor), you might not see the space. Use a different editor in your machine and you'll see it. Then remove them -- works perfectly afterward.

I was in a situation that the browser load the cache data from disk even I checked it disabled cache (I was using Chrome). All my CSS and JS were loading from server but not the web page. This was happening on both my local and Production.

To fixed it, I need to put an extra param in my URL to force the browser to get the web page from server, even the controller did not need it.

I was using ASP.Net, so here is my example :

//Controller function
public ActionResult Index()
    {
        return View();
    }
//Link
@Html.Action("Index", "Home", new { ts = DateTime.Now.Ticks.ToString()})

The result is, it will generate a link like: http://www.myweb.com/Home/Index?ts=636558555408282209

This is my situation and solution. Hopefully it could help somebody.
