If you need to update a property in the request, I recommend you to use the replace method from Request class used by Laravel

$request->replace(['property to update' => $newValue]);

for others who have troubles to add swift class into objective-c project. this is what work for me :

1. create NEW swift file. this will make xcode to prompt if you want xcode to create all settings for mix swift-objective-c project including brigde-header.h for you. press yes.
2. now, add your existing swift files you want to use in your project.
3. in the implementation file you are going to use the swift class add : #import "YOURPROJECTNAME-swift.h" . this file xcode create for you. if your xcode project is myProject then "myProject-swift.h"

and that's it. now create the swift class in your code like it was objective-c.

First Create Bitmap Image

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.image);

now set bitmap in Notification Builder Icon....

Notification.Builder.setLargeIcon(bmp);

You can adapt the solution you linked in How to sort ArrayList<Long> in Java in decreasing order? by wrapping it in a lambda:

.sorted((f1, f2) -> Long.compare(f2.lastModified(), f1.lastModified())

note that f2 is the first argument of Long.compare, not the second, so the result will be reversed.

You can use JSoup.

you can achieve that using Following example uses addBatch & executeBatch commands to execute multiple SQL commands simultaneously.

Batch Processing allows you to group related SQL statements into a batch and submit them with one call to the database. reference

When you send several SQL statements to the database at once, you reduce the amount of communication overhead, thereby improving performance.

• JDBC drivers are not required to support this feature. You should use the DatabaseMetaData.supportsBatchUpdates() method to determine if the target database supports batch update processing. The method returns true if your JDBC driver supports this feature.
• The addBatch() method of Statement, PreparedStatement, and CallableStatement is used to add individual statements to the batch. The executeBatch() is used to start the execution of all the statements grouped together.
• The executeBatch() returns an array of integers, and each element of the array represents the update count for the respective update statement.
• Just as you can add statements to a batch for processing, you can remove them with the clearBatch() method. This method removes all the statements you added with the addBatch() method. However, you cannot selectively choose which statement to remove.

EXAMPLE:

import java.sql.*;

public class jdbcConn {
   public static void main(String[] args) throws Exception{
      Class.forName("org.apache.derby.jdbc.ClientDriver");
      Connection con = DriverManager.getConnection
      ("jdbc:derby://localhost:1527/testDb","name","pass");

      Statement stmt = con.createStatement
      (ResultSet.TYPE_SCROLL_SENSITIVE,
      ResultSet.CONCUR_UPDATABLE);
      String insertEmp1 = "insert into emp values
      (10,'jay','trainee')";
      String insertEmp2 = "insert into emp values
      (11,'jayes','trainee')";
      String insertEmp3 = "insert into emp values
      (12,'shail','trainee')";
      con.setAutoCommit(false);
      stmt.addBatch(insertEmp1);//inserting Query in stmt
      stmt.addBatch(insertEmp2);
      stmt.addBatch(insertEmp3);
      ResultSet rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows before batch execution= "
      + rs.getRow());
      stmt.executeBatch();
      con.commit();
      System.out.println("Batch executed");
      rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows after batch execution= "
      + rs.getRow());
   }
}

The JSON spec says you CAN escape forward slash, but you don't have to.

You can fetch the connection string by using below line of code -

I was only interested for a trigger when a width of an element was changed (I don' care about height), so I created a jquery event that does exactly that, using an invisible iframe element.

$.event.special.widthChanged = {
  remove: function() {
      $(this).children('iframe.width-changed').remove();
  },
  add: function () {
      var elm = $(this);
      var iframe = elm.children('iframe.width-changed');
      if (!iframe.length) {
          iframe = $('<iframe/>').addClass('width-changed').prependTo(this);
      }
      var oldWidth = elm.width();
      function elmResized() {
          var width = elm.width();
          if (oldWidth != width) {
              elm.trigger('widthChanged', [width, oldWidth]);
              oldWidth = width;
          }
      }

      var timer = 0;
      var ielm = iframe[0];
      (ielm.contentWindow || ielm).onresize = function() {
          clearTimeout(timer);
          timer = setTimeout(elmResized, 20);
      };
  }
}

It requires the following css :

iframe.width-changed {
    width: 100%;
    display: block;
    border: 0;
    height: 0;
    margin: 0;
}

The font sizes in your question are an example of what ratio each header should be in comparison to each other, rather than what size they should be themselves (in pixels).

So in response to your question "Is there a 'best practice' for these for mobile phones? - say iphone screen size?", yes there probably is - but you might find what someone says is "best practice" does not work for your layout.

However, to help get you on the right track, this article about building responsive layouts provides a good example of how to calculate the base font-size in pixels in relation to device screen sizes.

The suggested font-sizes for screen resolutions suggested from that article are as follows:

@media (min-width: 858px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 780px) {
    html {
        font-size: 11px;
    }
}

@media (min-width: 702px) {
    html {
        font-size: 10px;
    }
}

@media (min-width: 724px) {
    html {
        font-size: 9px;
    }
}

@media (max-width: 623px) {
    html {
        font-size: 8px;
    }
}

http.request docs contains example how to receive body of the response through handling data event:

var options = {
  host: 'www.google.com',
  port: 80,
  path: '/upload',
  method: 'POST'
};

var req = http.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

http.get does the same thing as http.request except it calls req.end() automatically.

var options = {
  host: 'www.google.com',
  port: 80,
  path: '/index.html'
};

http.get(options, function(res) {
  console.log("Got response: " + res.statusCode);

  res.on("data", function(chunk) {
    console.log("BODY: " + chunk);
  });
}).on('error', function(e) {
  console.log("Got error: " + e.message);
});

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"

You can do what you want if you use an iterator object to go over the elements in your set. You can remove them on the go an it's ok. However removing them while in a for loop (either "standard", of the for each kind) will get you in trouble:

Set<Integer> set = new TreeSet<Integer>();
    set.add(1);
    set.add(2);
    set.add(3);

    //good way:
    Iterator<Integer> iterator = set.iterator();
    while(iterator.hasNext()) {
        Integer setElement = iterator.next();
        if(setElement==2) {
            iterator.remove();
        }
    }

    //bad way:
    for(Integer setElement:set) {
        if(setElement==2) {
            //might work or might throw exception, Java calls it indefined behaviour:
            set.remove(setElement);
        } 
    }

As per @mrgloom's comment, here are more details as to why the "bad" way described above is, well... bad :

Without getting into too much details about how Java implements this, at a high level, we can say that the "bad" way is bad because it is clearly stipulated as such in the Java docs:

https://docs.oracle.com/javase/8/docs/api/java/util/ConcurrentModificationException.html

stipulate, amongst others, that (emphasis mine):

"For example, it is not generally permissible for one thread to modify a Collection while another thread is iterating over it. In general, the results of the iteration are undefined under these circumstances. Some Iterator implementations (including those of all the general purpose collection implementations provided by the JRE) may choose to throw this exception if this behavior is detected" (...)

"Note that this exception does not always indicate that an object has been concurrently modified by a different thread. If a single thread issues a sequence of method invocations that violates the contract of an object, the object may throw this exception. For example, if a thread modifies a collection directly while it is iterating over the collection with a fail-fast iterator, the iterator will throw this exception."

To go more into details: an object that can be used in a forEach loop needs to implement the "java.lang.Iterable" interface (javadoc here). This produces an Iterator (via the "Iterator" method found in this interface), which is instantiated on demand, and will contain internally a reference to the Iterable object from which it was created. However, when an Iterable object is used in a forEach loop, the instance of this iterator is hidden to the user (you cannot access it yourself in any way).

This, coupled with the fact that an Iterator is pretty stateful, i.e. in order to do its magic and have coherent responses for its "next" and "hasNext" methods it needs that the backing object is not changed by something else than the iterator itself while it's iterating, makes it so that it will throw an exception as soon as it detects that something changed in the backing object while it is iterating over it.

Java calls this "fail-fast" iteration: i.e. there are some actions, usually those that modify an Iterable instance (while an Iterator is iterating over it). The "fail" part of the "fail-fast" notion refers to the ability of an Iterator to detect when such "fail" actions happen. The "fast" part of the "fail-fast" (and, which in my opinion should be called "best-effort-fast"), will terminate the iteration via ConcurrentModificationException as soon as it can detect that a "fail" action has happen.

You can use -webkit-border-radius: 0;. Like this:-

-webkit-border-radius: 0;
border: 0;
outline: 1px solid grey;
outline-offset: -1px;

This will give square corners as well as dropdown arrows. Using -webkit-appearance: none; is not recommended as it will turn off all the styling done by Chrome.

I'm going to order this guide by the level of skill you have in Haskell, going from an absolute beginner right up to an expert. Note that this process will take many months (years?), so it is rather long.

Absolute Beginner

Firstly, Haskell is capable of anything, with enough skill. It is very fast (behind only C and C++ in my experience), and can be used for anything from simulations to servers, guis and web applications.

However there are some problems that are easier to write for a beginner in Haskell than others. Mathematical problems and list process programs are good candidates for this, as they only require the most basic of Haskell knowledge to be able to write.

Some good guides to learning the very basics of Haskell are the Happy Learn Haskell Tutorial and the first 6 chapters of Learn You a Haskell for Great Good (or its JupyterLab adaptation). While reading these, it is a very good idea to also be solving simple problems with what you know.

Another two good resources are Haskell Programming from first principles, and Programming in Haskell. They both come with exercises for each chapter, so you have small simple problems matching what you learned on the last few pages.

A good list of problems to try is the haskell 99 problems page. These start off very basic, and get more difficult as you go on. It is very good practice doing a lot of those, as they let you practice your skills in recursion and higher order functions. I would recommend skipping any problems that require randomness as that is a bit more difficult in Haskell. Check this SO question in case you want to test your solutions with QuickCheck (see Intermediate below).

Once you have done a few of those, you could move on to doing a few of the Project Euler problems. These are sorted by how many people have completed them, which is a fairly good indication of difficulty. These test your logic and Haskell more than the previous problems, but you should still be able to do the first few. A big advantage Haskell has with these problems is Integers aren't limited in size. To complete some of these problems, it will be useful to have read chapters 7 and 8 of learn you a Haskell as well.

Beginner

After that you should have a fairly good handle on recursion and higher order functions, so it would be a good time to start doing some more real world problems. A very good place to start is Real World Haskell (online book, you can also purchase a hard copy). I found the first few chapters introduced too much too quickly for someone who has never done functional programming/used recursion before. However with the practice you would have had from doing the previous problems you should find it perfectly understandable.

Working through the problems in the book is a great way of learning how to manage abstractions and building reusable components in Haskell. This is vital for people used to object-orientated (oo) programming, as the normal oo abstraction methods (oo classes) don't appear in Haskell (Haskell has type classes, but they are very different to oo classes, more like oo interfaces). I don't think it is a good idea to skip chapters, as each introduces a lot new ideas that are used in later chapters.

After a while you will get to chapter 14, the dreaded monads chapter (dum dum dummmm). Almost everyone who learns Haskell has trouble understanding monads, due to how abstract the concept is. I can't think of any concept in another language that is as abstract as monads are in functional programming. Monads allows many ideas (such as IO operations, computations that might fail, parsing,...) to be unified under one idea. So don't feel discouraged if after reading the monads chapter you don't really understand them. I found it useful to read many different explanations of monads; each one gives a new perspective on the problem. Here is a very good list of monad tutorials. I highly recommend the All About Monads, but the others are also good.

Also, it takes a while for the concepts to truly sink in. This comes through use, but also through time. I find that sometimes sleeping on a problem helps more than anything else! Eventually, the idea will click, and you will wonder why you struggled to understand a concept that in reality is incredibly simple. It is awesome when this happens, and when it does, you might find Haskell to be your favorite imperative programming language :)

To make sure that you are understanding Haskell type system perfectly, you should try to solve 20 intermediate haskell exercises. Those exercises using fun names of functions like "furry" and "banana" and helps you to have a good understanding of some basic functional programming concepts if you don't have them already. Nice way to spend your evening with a bunch of papers covered with arrows, unicorns, sausages and furry bananas.

Intermediate

Once you understand Monads, I think you have made the transition from a beginner Haskell programmer to an intermediate haskeller. So where to go from here? The first thing I would recommend (if you haven't already learnt them from learning monads) is the various types of monads, such as Reader, Writer and State. Again, Real world Haskell and All about monads gives great coverage of this. To complete your monad training learning about monad transformers is a must. These let you combine different types of Monads (such as a Reader and State monad) into one. This may seem useless to begin with, but after using them for a while you will wonder how you lived without them.

Now you can finish the real world Haskell book if you want. Skipping chapters now doesn't really matter, as long as you have monads down pat. Just choose what you are interested in.

With the knowledge you would have now, you should be able to use most of the packages on cabal (well the documented ones at least...), as well as most of the libraries that come with Haskell. A list of interesting libraries to try would be:

• Parsec: for parsing programs and text. Much better than using regexps. Excellent documentation, also has a real world Haskell chapter.

• QuickCheck: A very cool testing program. What you do is write a predicate that should always be true (eg length (reverse lst) == length lst). You then pass the predicate the QuickCheck, and it will generate a lot of random values (in this case lists) and test that the predicate is true for all results. See also the online manual.

• HUnit: Unit testing in Haskell.

• gtk2hs: The most popular gui framework for Haskell, lets you write gtk applications.

• happstack: A web development framework for Haskell. Doesn't use databases, instead a data type store. Pretty good docs (other popular frameworks would be snap and yesod).

Also, there are many concepts (like the Monad concept) that you should eventually learn. This will be easier than learning Monads the first time, as your brain will be used to dealing with the level of abstraction involved. A very good overview for learning about these high level concepts and how they fit together is the Typeclassopedia.

• Applicative: An interface like Monads, but less powerful. Every Monad is Applicative, but not vice versa. This is useful as there are some types that are Applicative but are not Monads. Also, code written using the Applicative functions is often more composable than writing the equivalent code using the Monad functions. See Functors, Applicative Functors and Monoids from the learn you a haskell guide.

• Foldable,Traversable: Typeclasses that abstract many of the operations of lists, so that the same functions can be applied to other container types. See also the haskell wiki explanation.

• Monoid: A Monoid is a type that has a zero (or mempty) value, and an operation, notated <> that joins two Monoids together, such that x <> mempty = mempty <> x = x and x <> (y <> z) = (x <> y) <> z. These are called identity and associativity laws. Many types are Monoids, such as numbers, with mempty = 0 and <> = +. This is useful in many situations.

• Arrows: Arrows are a way of representing computations that take an input and return an output. A function is the most basic type of arrow, but there are many other types. The library also has many very useful functions for manipulating arrows - they are very useful even if only used with plain old Haskell functions.

• Arrays: the various mutable/immutable arrays in Haskell.

• ST Monad: lets you write code with a mutable state that runs very quickly, while still remaining pure outside the monad. See the link for more details.

• FRP: Functional Reactive Programming, a new, experimental way of writing code that handles events, triggers, inputs and outputs (such as a gui). I don't know much about this though. Paul Hudak's talk about yampa is a good start.

There are a lot of new language features you should have a look at. I'll just list them, you can find lots of info about them from google, the haskell wikibook, the haskellwiki.org site and ghc documentation.

• Multiparameter type classes/functional dependencies
• Type families
• Existentially quantified types
• Phantom types
• GADTS
• others...

A lot of Haskell is based around category theory, so you may want to look into that. A good starting point is Category Theory for Computer Scientist. If you don't want to buy the book, the author's related article is also excellent.

Finally you will want to learn more about the various Haskell tools. These include:

• ghc (and all its features)
• cabal: the Haskell package system
• darcs: a distributed version control system written in Haskell, very popular for Haskell programs.
• haddock: a Haskell automatic documentation generator

While learning all these new libraries and concepts, it is very useful to be writing a moderate-sized project in Haskell. It can be anything (e.g. a small game, data analyser, website, compiler). Working on this will allow you to apply many of the things you are now learning. You stay at this level for ages (this is where I'm at).

Expert

It will take you years to get to this stage (hello from 2009!), but from here I'm guessing you start writing phd papers, new ghc extensions, and coming up with new abstractions.

Getting Help

Finally, while at any stage of learning, there are multiple places for getting information. These are:

• the #haskell irc channel
• the mailing lists. These are worth signing up for just to read the discussions that take place - some are very interesting.
• other places listed on the haskell.org home page

Conclusion

Well this turned out longer than I expected... Anyway, I think it is a very good idea to become proficient in Haskell. It takes a long time, but that is mainly because you are learning a completely new way of thinking by doing so. It is not like learning Ruby after learning Java, but like learning Java after learning C. Also, I am finding that my object-orientated programming skills have improved as a result of learning Haskell, as I am seeing many new ways of abstracting ideas.

No offense, but it's unclever to change class on-the-fly as it forces the CSS interpreter to recalculate the visual presentation of the entire web page.

The reason is that it is nearly impossible for the CSS interpreter to know if any inheritance or cascading could be changed, so the short answer is:

Never ever change className on-the-fly !-)

But usually you'll only need to change a property or two, and that is easily implemented:

function highlight(elm){
    elm.style.backgroundColor ="#345";
    elm.style.color = "#fff";
}

You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:

clean:
    @if [ "test" = "test" ]; then\
        echo "Hello world";\
    fi

Note that the closing ";" and "\" are necessary.

See ReceivedTime Property

http://msdn.microsoft.com/en-us/library/office/aa171873(v=office.11).aspx

You added another \ to the end of C:\Temp\ in the SaveAs File line. Could be a problem. Do a test first before adding a path separator.

dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  
saveFolder = "C:\Temp"

You have not set objAtt so there is no need for "Set objAtt = Nothing". If there was it would be just before End Sub not in the loop.

Public Sub saveAttachtoDisk (itm As Outlook.MailItem) 
    Dim objAtt As Outlook.Attachment 
    Dim saveFolder As String Dim dateFormat
    dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  saveFolder = "C:\Temp"
    For Each objAtt In itm.Attachments
        objAtt.SaveAsFile saveFolder & "\" & dateFormat & objAtt.DisplayName
    Next
End Sub

This is usually due to Security settings. It is a "trap" set for first time users to allow macros then take it away. http://www.slipstick.com/outlook-developer/how-to-use-outlooks-vba-editor/

If you want to use the catch() of the Observable you need to use Observable.throw() method before delegating the error response to a method

import { Injectable } from '@angular/core';_x000D_
import { Headers, Http, ResponseOptions} from '@angular/http';_x000D_
import { AuthHttp } from 'angular2-jwt';_x000D_
_x000D_
import { MEAT_API } from '../app.api';_x000D_
_x000D_
import { Observable } from 'rxjs/Observable';_x000D_
import 'rxjs/add/operator/map';_x000D_
import 'rxjs/add/operator/catch';_x000D_
_x000D_
@Injectable()_x000D_
export class CompareNfeService {_x000D_
_x000D_
_x000D_
  constructor(private http: AuthHttp) {}_x000D_
_x000D_
  envirArquivos(order): Observable < any > {_x000D_
    const headers = new Headers();_x000D_
    return this.http.post(`${MEAT_API}compare/arquivo`, order,_x000D_
        new ResponseOptions({_x000D_
          headers: headers_x000D_
        }))_x000D_
      .map(response => response.json())_x000D_
      .catch((e: any) => Observable.throw(this.errorHandler(e)));_x000D_
  }_x000D_
_x000D_
  errorHandler(error: any): void {_x000D_
    console.log(error)_x000D_
  }_x000D_
}

Using Observable.throw() worked for me

if duplicate and ordering items are problem :

[i for i in a if not i in b or b.remove(i)]

a = [1,2,3,3,3,3,4]
b = [1,3]
result: [2, 3, 3, 3, 4]

An equivalent of in_array with underscore is _.indexOf

Examples:

_.indexOf([3, 5, 8], 8); // returns 2, the index of 8 _.indexOf([3, 5, 8], 10); // returns -1, not found

You could try:

#applyCSS .ui-bar-a {property:value}
#applyCSS .ui-bar-a .ui-link-inherit {property:value}

Etc, etc... Is that what you're looking for?

swift version:

var button = UIButton()

newGameButton.setTitle("????? ????", for: .normal)
newGameButton.setImage(UIImage(named: "energi"), for: .normal)
newGameButton.backgroundColor = .blue
newGameButton.imageEdgeInsets.left = -50

In addition to James's answer:

If you need to disable the link use

$('a[data-toggle="tab"]').addClass('disabled');

If you need to prevent a disabled link from loading the tab

$('a[data-toggle="tab"]').click(function(e){

            if($this.hasClass("disabled")){

                e.preventDefault();

                e.stopPropagation();

                e.stopImmediatePropagation();

                return false;

            }
}

If you need to unable the link

$('a[data-toggle="tab"]').removeClass('disabled');

according to the mySQL reference manual this the syntax of using if and else statement :

IF search_condition THEN statement_list
[ELSEIF search_condition THEN statement_list] ...
[ELSE statement_list]
END IF

So regarding your query :

x = IF((action=2)&&(state=0),1,2);

or you can use

IF ((action=2)&&(state=0)) then 
state = 1;
ELSE 
state = 2;
END IF;

There is good example in this link : http://easysolutionweb.com/sql-pl-sql/how-to-use-if-and-else-in-mysql/

I posted something similar here

From Joachim's answer, from Dianne Hackborn:

http://groups.google.com/group/android-developers/browse_thread/thread/d2a5c203dad6ec42

I ended up just using:

FragmentManager fm = getActivity().getSupportFragmentManager();
for(int i = 0; i < fm.getBackStackEntryCount(); ++i) {    
    fm.popBackStack();
}

But could equally have used something like:

((AppCompatActivity)getContext()).getSupportFragmentManager().popBackStack(String name, FragmentManager.POP_BACK_STACK_INCLUSIVE)

Which will pop all states up to the named one. You can then just replace the fragment with what you want

I found solution. It works fine when I throw away next line from form:

enctype="multipart/form-data"

And now it pass all parameters at request ok:

 <form action="/registration" method="post">
   <%-- error messages --%>

LocalDate.now()
         .toString() 

2017-01-23

Better to specify the desired/expected time zone explicitly.

LocalDate.now( ZoneId.of( "America/Montreal" ) )
         .toString() 

java.time

The modern way as of Java 8 and later is with the java.time framework.

Specify the time zone, as the date varies around the world at any given moment.

ZoneId zoneId = ZoneId.of( "America/Montreal" ) ;  // Or ZoneOffset.UTC or ZoneId.systemDefault()
LocalDate today = LocalDate.now( zoneId ) ;
String output = today.toString() ;

2017-01-23

By default you get a String in standard ISO 8601 format.

For other formats use the java.time.format.DateTimeFormatter class.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

If you meant disable all the inputs in an Angular form at once:

1- Reactive Forms:

myFormGroup.disable() // where myFormGroup is a FormGroup 

2- Template driven forms (NgForm):

You should get hold of the NgForm in a NgForm variable (for ex. named myNgForm) then

myNgForm.form.disable() // where form here is an attribute of NgForm 
                      // & of type FormGroup so it accepts the disable() function

In case of NgForm , take care to call the disable method in the right time

To determine when to call it, You can find more details in this Stackoverflow answer

Pandas timestamp differences returns a datetime.timedelta object. This can easily be converted into hours by using the *as_type* method, like so

import pandas
df = pandas.DataFrame(columns=['to','fr','ans'])
df.to = [pandas.Timestamp('2014-01-24 13:03:12.050000'), pandas.Timestamp('2014-01-27 11:57:18.240000'), pandas.Timestamp('2014-01-23 10:07:47.660000')]
df.fr = [pandas.Timestamp('2014-01-26 23:41:21.870000'), pandas.Timestamp('2014-01-27 15:38:22.540000'), pandas.Timestamp('2014-01-23 18:50:41.420000')]
(df.fr-df.to).astype('timedelta64[h]')

to yield,

0    58
1     3
2     8
dtype: float64

Log.e("Main",response.body!!.string())

in above line !! is the thing using which you can get the json from response body

For Word 2010 and 2013, go to File > Options > Customize Ribbon > Keyboard Shortcuts > All Commands (in left list) > Color: (in right list) -- at this point, you type in the short cut (such as Alt+r) and select the color (such as red). (This actually goes back to 2003 but I don't have that installed to provide the pathway.)

If you have a javax.net.ssl.SSLSocket class reference in your code, you can set the enabled TLS protocols by a call to SSLSocket.setEnabledProtocols():

import javax.net.ssl.*;
import java.net.*; 
...
Socket socket = SSLSocketFactory.getDefault().createSocket();
...
if (socket instanceof SSLSocket) {
   // "TLSv1.0" gives IllegalArgumentException in Java 8
   String[] protos = {"TLSv1.2", "TLSv1.1"}
   ((SSLSocket)socket).setEnabledProtocols(protos);
}

For those who don't want elegant solutions, just a quick and dirty way to stop those messages, here is a solution that worked for me (I use Hibernate 4.3.6 and Eclipse and no answers provided above (or found on the internet) worked; neither log4j config files nor setting the logging level programatically)

public static void main(String[] args) {
    //magical - do not touch
    @SuppressWarnings("unused")
    org.jboss.logging.Logger logger = org.jboss.logging.Logger.getLogger("org.hibernate");
    java.util.logging.Logger.getLogger("org.hibernate").setLevel(java.util.logging.Level.WARNING); //or whatever level you need

    ...
}

As I understand, you want to recursively copy test directory into /home/server/ path...

This can be done as:

-cp -rf /home/server/folder/test/* /home/server/

Hope this helps

Another option might be numpy.asarray:

import numpy as np
a = ["1.1", "2.2", "3.2"]
b = np.asarray(a, dtype=np.float64, order='C')

For Python 2*:

print a, type(a), type(a[0])
print b, type(b), type(b[0])

resulting in:

['1.1', '2.2', '3.2'] <type 'list'> <type 'str'>
[1.1 2.2 3.2] <type 'numpy.ndarray'> <type 'numpy.float64'>

To get the time from datetime, we can use

SELECT CONVERT(VARCHAR(20), GETDATE(), 114)

I stumbled across this solution in the documentation for the Create Database statement in the help for SQL Server:

SELECT SUBSTRING(physical_name, 1, CHARINDEX(N'master.mdf', LOWER(physical_name)) - 1)
                  FROM master.sys.master_files
                  WHERE database_id = 1 AND file_id = 1

Your question is a little unclear...as the part that you indicate you want to bold in Excel is a DataGridView in the import from word method. Do you maybe want to bold the first row in the excel document?

using xl = Microsoft.Office.Interop.Excel;

xl.Range rng = (xl.Range)xlWorkSheet.Rows[0];
rng.Font.Bold = true;

Simple as that!

PDB is an abbreviation for Program Data Base. As the name suggests, it is a repository (persistent storage such as databases) to maintain information required to run your program in debug mode. It contains many important relevant information required while you debug your code (in Visual Studio), for e.g. at what points you have inserted break points where you expect the debugger to break in Visual Studio.

This is the reason why many times Visual Studio fails to hit the break points if you remove the *.pdb files from your debug folders. Visual Studio debugger is also able to tell you the precise line number of code file at which an exception occurred in a stack trace with the help of *.pdb files. So effectively pdb files are really a boon to developers while debugging a program.

Generally it is not recommended to exclude the generation of *.pdb files. From production release stand-point what you should be doing is create the pdb files but don't ship them to customer site in product installer. Preserve all the generated PDB files on to a symbol server from where it can be used/referenced in future if required. Specially for cases when you debug issues like process crash. When you start analysing the crash dump files and if your original *.pdb files created during the build process are not preserved then Visual Studio will not be able to make out the exact line of code which is causing crash.

If you still want to disable generation of *.pdb files altogether for any release then go to properties of the project -> Build Tab -> Click on Advanced button -> Choose none from "Debug Info" drop-down box -> press OK as shown in the snapshot below.

Note: This setting will have to be done separately for "Debug" and "Release" build configurations.

I think i'am late for the party but when you use a wildfly, you can add an default-encoding to the standalone.xml. Just search in the standalone.xml for

<servlet-container name="default"> 

and add encoding like this:

<servlet-container name="default" default-encoding="UTF-8">

to print only the certificate chain and not the server's certificate:

# MYHOST=myhost.com
# MYPORT=443
# openssl s_client -connect ${MYHOST}:${MYPORT} -showcerts 2>/dev/null </dev/null | awk '/^.*'"${MYHOST}"'/,/-----END CERTIFICATE-----/{next;}/-----BEGIN/,/-----END CERTIFICATE-----/{print}'

to update CA trust on CentOS/RHEL 6/7 :

# update-ca-trust enable
# openssl s_client -connect ${MYHOST}:${MYPORT} -showcerts 2>/dev/null </dev/null | awk '/^.*'"${MYHOST}"'/,/-----END CERTIFICATE-----/{next;}/-----BEGIN/,/-----END CERTIFICATE-----/{print}' >/etc/pki/ca-trust/source/anchors/myca.cert
# update-ca-trust extract

on CentOS/RHEL 5:

# openssl s_client -connect ${MYHOST}:${MYPORT} -showcerts 2>/dev/null </dev/null | awk '/^.*'"${MYHOST}"'/,/-----END CERTIFICATE-----/{next;}/-----BEGIN/,/-----END CERTIFICATE-----/{print}' >>/etc/pki/tls/certs/ca-bundle.crt

While it's possible that this is due to a jar file missing from your classpath, it may not be.

It is important to keep two or three different exceptions strait in our head in this case:

1. java.lang.ClassNotFoundException This exception indicates that the class was not found on the classpath. This indicates that we were trying to load the class definition, and the class did not exist on the classpath.

2. java.lang.NoClassDefFoundError This exception indicates that the JVM looked in its internal class definition data structure for the definition of a class and did not find it. This is different than saying that it could not be loaded from the classpath. Usually this indicates that we previously attempted to load a class from the classpath, but it failed for some reason - now we're trying again, but we're not even going to try to load it, because we failed loading it earlier. The earlier failure could be a ClassNotFoundException or an ExceptionInInitializerError (indicating a failure in the static initialization block) or any number of other problems. The point is, a NoClassDefFoundError is not necessarily a classpath problem.

I would look at the source for javax.mail.Authenticator, and see what it is doing in it's static initializer. (Look at static variable initialization and the static block, if there is one.) If you aren't getting a ClassNotFoundException prior to the NoClassDefFoundError, you're almost guaranteed that it's a static initialization problem.

I have seen similar errors quite frequently when the hosts file incorrectly defines the localhost address, and the static initialization block relies on InetAddress.getLocalHost(). 127.0.0.1 should point to 'localhost' (and probably also localhost.localdomain). It should NOT point to the actual host name of the machine (although for some reason, many older RedHat Linux installers liked to set it incorrectly).

I figured it would also vary based on the number of partitions (number of iterators within the container list) -- your comment didn't mention how many partitions there were of the thirty items.

Note: METHODS should probably be accumulated with a decorator, but I figure it'd be easier for people to read this way.

This way worked for me:

adding the path that you like:

export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add

checking: you can run 'export' cmd and check the output or you can check it using this cmd:

python -c "import sys; print(sys.path)"

I had a similar thing happen to me. I didn't want to stage the files just yet so I added them with git add and then just did git reset. This basically just added and then unstaged my changes but cleared the unmerged paths.

I found a better way of doing it so you can get a input from a txtbox or have something be generated in that text box and be able to click a button to do it.!

import java.awt.datatransfer.*;
import java.awt.Toolkit;

private void /* Action performed when the copy to clipboard button is clicked */ {
    String ctc = txtCommand.getText().toString();
    StringSelection stringSelection = new StringSelection(ctc);
    Clipboard clpbrd = Toolkit.getDefaultToolkit().getSystemClipboard();
    clpbrd.setContents(stringSelection, null);
}

// txtCommand is the variable of a text box

To Get TEXT attributes added from admin to front end on product listing page.

Thanks Anita Mourya

I have found there is two methods. Let say product attribute called "na_author" is added from backend as text field.

METHOD 1

on list.phtml

<?php $i=0; foreach ($_productCollection as $_product): ?>

FOR EACH PRODUCT LOAD BY SKU AND GET ATTRIBUTE INSIDE FOREACH

<?php
$product = Mage::getModel('catalog/product')->loadByAttribute('sku',$_product->getSku());
$author = $product['na_author'];
?>

<?php
if($author!=""){echo "<br /><span class='home_book_author'>By ".$author ."</span>";} else{echo "";}
?>

METHOD 2

Mage/Catalog/Block/Product/List.phtml OVER RIDE and set in 'local folder'

i.e. Copy From

Mage/Catalog/Block/Product/List.phtml

and PASTE TO

app/code/local/Mage/Catalog/Block/Product/List.phtml

change the function by adding 2 lines shown in bold below.

protected function _getProductCollection()
{
       if (is_null($this->_productCollection)) {
           $layer = Mage::getSingleton('catalog/layer');
           /* @var $layer Mage_Catalog_Model_Layer */
           if ($this->getShowRootCategory()) {
               $this->setCategoryId(Mage::app()->getStore()->getRootCategoryId());
           }

           // if this is a product view page
           if (Mage::registry('product')) {
               // get collection of categories this product is associated with
               $categories = Mage::registry('product')->getCategoryCollection()
                   ->setPage(1, 1)
                   ->load();
               // if the product is associated with any category
               if ($categories->count()) {
                   // show products from this category
                   $this->setCategoryId(current($categories->getIterator()));
               }
           }

           $origCategory = null;
           if ($this->getCategoryId()) {
               $category = Mage::getModel('catalog/category')->load($this->getCategoryId());

               if ($category->getId()) {
                   $origCategory = $layer->getCurrentCategory();
                   $layer->setCurrentCategory($category);
               }
           }
           $this->_productCollection = $layer->getProductCollection();

           $this->prepareSortableFieldsByCategory($layer->getCurrentCategory());

           if ($origCategory) {
               $layer->setCurrentCategory($origCategory);
           }
       }
       **//CMI-PK added na_author to filter on product listing page//
       $this->_productCollection->addAttributeToSelect('na_author');**
       return $this->_productCollection;

}

and you will be happy to see it....!!

If you want to remove EVERYTHING :

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

I may be late for this but I had somewhat the same problem.

I needed to pass both the id and the name into my model but all the orthodox solutions had me make code on the controller to handle the change.

I macgyvered my way out of it using a filter.

<select 
        ng-model="selected_id" 
        ng-options="o.id as o.name for o in options" 
        ng-change="selected_name=(options|filter:{id:selected_id})[0].name">
</select>
<script>
  angular.module("app",[])
  .controller("ctrl",['$scope',function($scope){
    $scope.options = [
      {id:1, name:'Starbuck'},
      {id:2, name:'Appolo'},
      {id:3, name:'Saul Tigh'},
      {id:4, name:'Adama'}
    ]
  }])
</script>

The "trick" is here:

ng-change="selected_name=(options|filter:{id:selected_id})[0].name"

I'm using the built-in filter to retrieve the correct name for the id

Here's a plunkr with a working demo.

If you are to use the

<!-- saved from url=(0014)about:internet -->

or

<!-- saved from url=(0016)http://localhost -->

make sure the HTML file is saved in windows/dos format with "\r\n" as line breaks after the statement. Otherwise I couldn't make it work.

I use WinMerge. It is free and works pretty well (works for files and directories).

A bit late to the party, but Krux has created a script for this, called Postscribe. We were able to use this to get past this issue.

I found this on github:

    log.history.push(arguments);
    if (this.console) {
        var args = arguments,
            newarr;
        args.callee = args.callee.caller;
        newarr = [].slice.call(args);
        if (typeof console.log === 'object') log.apply.call(console.log, console, newarr);
        else console.log.apply(console, newarr);
    }
};

// make it safe to use console.log always
(function(a) {
    function b() {}
    for (var c = "assert,count,debug,dir,dirxml,error,exception,group,groupCollapsed,groupEnd,info,log,markTimeline,profile,profileEnd,time,timeEnd,trace,warn".split(","), d; !! (d = c.pop());) {

} ());

The div element has its own alignment attribute, align.

<div align="center">
  my text here.
</div>

$('.IsBestAnswer').removeClass('IsBestAnswer').addClass('bestanswer');

Your code has two problems:

1. The selector .IsBestAnswe does not match what you thought
2. It's addClass(), not addclass().

Also, I'm not sure whether you want to replace the class or add it. The above will replace, but remove the .removeClass('IsBestAnswer') part to add only:

$('.IsBestAnswer').addClass('bestanswer');

You should decide whether to use camelCase or all-lowercase in your CSS classes too (e.g. bestAnswer vs. bestanswer).

date command didnt provide milli seconds on OS X, so used an alias from python

millis(){  python -c "import time; print(int(time.time()*1000))"; }

OR

alias millis='python -c "import time; print(int(time.time()*1000))"'

EDIT: following the comment from @CharlesDuffy. Forking any child process takes extra time.

$ time date +%s%N
1597103627N
date +%s%N  0.00s user 0.00s system 63% cpu 0.006 total

Python is still improving it's VM start time, and it is not as fast as ahead-of-time compiled code (such as date).

On my machine, it took about 30ms - 60ms (that is 5x-10x of 6ms taken by date)

$ time python -c "import time; print(int(time.time()*1000))"
1597103899460
python -c "import time; print(int(time.time()*1000))"  0.03s user 0.01s system 83% cpu 0.053 total

I figured awk is lightweight than python, so awk takes in the range of 6ms to 12ms (i.e. 1x to 2x of date):

$ time awk '@load "time"; BEGIN{print int(1000 * gettimeofday())}'
1597103729525
awk '@load "time"; BEGIN{print int(1000 * gettimeofday())}'  0.00s user 0.00s system 74% cpu 0.010 total

This answer attempts a pragmatic summary of the many great answers on this page:

^{jeb's great answer deserves special mention, because it really goes in-depth and covers many edge cases.
Notably, he points out that a misconstructed variable/parameter reference such as %~ can break any of the solutions below - including REM lines.}

Whole-line comments - the only directly supported style:

• REM (or case variations thereof) is the only official comment construct, and is the safest choice - see Joey's helpful answer.

• :: is a (widely used) hack, which has pros and cons:

  • Pros:

    • Visual distinctiveness and, possibly, ease of typing.
    • Speed, although that will probably rarely matter - see jeb's great answer and Rob van der Woude's excellent blog post.

  • Cons:

    • Inside (...) blocks, :: can break the command, and the rules for safe use are restrictive and not easy to remember - see below.

If you do want to use ::, you have these choices:

• Either: To be safe, make an exception inside (...) blocks and use REM there, or do not place comments inside (...) altogether.
• Or: Memorize the painfully restrictive rules for safe use of :: inside (...), which are summarized in the following snippet:

@echo off

for %%i in ("dummy loop") do (

  :: This works: ONE comment line only, followed by a DIFFERENT, NONBLANK line.
  date /t

  REM If you followed a :: line directly with another one, the *2nd* one
  REM would generate a spurious "The system cannot find the drive specified."
  REM error message and potentially execute commands inside the comment.
  REM In the following - commented-out - example, file "out.txt" would be
  REM created (as an empty file), and the ECHO command would execute.
  REM   :: 1st line
  REM   :: 2nd line > out.txt & echo HERE

  REM NOTE: If :: were used in the 2 cases explained below, the FOR statement
  REM would *break altogether*, reporting:
  REM  1st case: "The syntax of the command is incorrect."
  REM  2nd case: ") was unexpected at this time."

  REM Because the next line is *blank*, :: would NOT work here.

  REM Because this is the *last line* in the block, :: would NOT work here.
)

Emulation of other comment styles - inline and multi-line:

Note that none of these styles are directly supported by the batch language, but can be emulated.

Inline comments:

<sup>* The code snippets below use ver as a stand-in for an arbitrary command, so as to facilitate experimentation.
* To make SET commands work correctly with inline comments, double-quote the name=value part; e.g., SET "foo=bar".[1]</sup>

In this context we can distinguish two subtypes:

• EOL comments ([to-the-]end-of-line), which can be placed after a command, and invariably extend to the end of the line (again, courtesy of jeb's answer):

  • ver & REM <comment> takes advantage of the fact that REM is a valid command and & can be used to place an additional command after an existing one.
  • ver & :: <comment> works too, but is really only usable outside of (...) blocks, because its safe use there is even more limited than using :: standalone.

• Intra-line comments, which be placed between multiple commands on a line or ideally even inside of a given command.
  Intra-line comments are the most flexible (single-line) form and can by definition also be used as EOL comments.

  • ver & REM^. ^<comment^> & ver allows inserting a comment between commands (again, courtesy of jeb's answer), but note how < and > needed to be ^-escaped, because the following chars. cannot be used as-is: < > | (whereas unescaped & or && or || start the next command).

  • %= <comment> =%, as detailed in dbenham's great answer, is the most flexible form, because it can be placed inside a command (among the arguments).
    It takes advantage of variable-expansion syntax in a way that ensures that the expression always expands to the empty string - as long as the comment text contains neither % nor :
    Like REM, %= <comment> =% works well both outside and inside (...) blocks, but it is more visually distinctive; the only down-sides are that it is harder to type, easier to get wrong syntactically, and not widely known, which can hinder understanding of source code that uses the technique.

Multi-line (whole-line block) comments:

• James K's answer shows how to use a goto statement and a label to delimit a multi-line comment of arbitrary length and content (which in his case he uses to store usage information).

• Zee's answer shows how to use a "null label" to create a multi-line comment, although care must be taken to terminate all interior lines with ^.

• Rob van der Woude's blog post mentions another somewhat obscure option that allows you to end a file with an arbitrary number of comment lines: An opening ( only causes everything that comes after to be ignored, as long as it doesn't contain a ( non-^-escaped) ), i.e., as long as the block is not closed.

^{[1] Using SET "foo=bar" to define variables - i.e., putting double quotes around the name and = and the value combined - is necessary in commands such as SET "foo=bar" & REM Set foo to bar., so as to ensure that what follows the intended variable value (up to the next command, in this case a single space) doesn't accidentally become part of it.
(As an aside: SET foo="bar" would not only not avoid the problem, it would make the double quotes part of the value).
Note that this problem is inherent to SET and even applies to accidental trailing whitespace following the value, so it is advisable to always use the SET "foo=bar" approach.}

I usually use data-* attributes in HTML.

<div class="service-container" data-service="<?php echo $myService->getValue(); ?>">

</div>

<script>
    $(document).ready(function() {
        $('.service-container').each(function() {
            var container = $(this);
            var service = container.data('service');

            // Variable "service" now contains the value of $myService->getValue();
        });
    });
</script>

This example uses jQuery, but it can be adapted for another library or vanilla JavaScript.

You can read more about the dataset property here: https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement.dataset

The TensorFlow Convolution example gives an overview about the difference between SAME and VALID :

• For the SAME padding, the output height and width are computed as:

  out_height = ceil(float(in_height) / float(strides[1]))
  out_width  = ceil(float(in_width) / float(strides[2]))
  

And

• For the VALID padding, the output height and width are computed as:

  out_height = ceil(float(in_height - filter_height + 1) / float(strides[1]))
  out_width  = ceil(float(in_width - filter_width + 1) / float(strides[2]))
  

The chart seem to be async so you will probably need to provide a callback when the animation has finished or else the canvas will be empty.

var options = {
    bezierCurve : false,
    onAnimationComplete: done  /// calls function done() {} at end
};

This should work for you. Tested all the way back to SQL 2000.

create table #user (username varchar(25))

insert into #user (username) values ('Paul')
insert into #user (username) values ('John')
insert into #user (username) values ('Mary')

declare @tmp varchar(250)
SET @tmp = ''
select @tmp = @tmp + username + ', ' from #user

select SUBSTRING(@tmp, 0, LEN(@tmp))

Color picker plugin for Interface Builder

There's a nice color picker from Panic which works well with IB: http://panic.com/~wade/picker/

Xcode plugin

This one gives you a GUI for choosing colors: http://www.youtube.com/watch?v=eblRfDQM0Go

Objective-C

UIColor *color = [UIColor colorWithRed:(160/255.0) green:(97/255.0) blue:(5/255.0) alpha:1.0];

Swift

let color = UIColor(red: 160/255, green: 97/255, blue: 5/255, alpha: 1.0)

Pods and libraries

There's a nice pod named MPColorTools: https://github.com/marzapower/MPColorTools

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

Just check my scripts it's working well:

  function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // Loop through the FileList and render image files as thumbnails.
    for (var i = 0, f; f = files[i]; i++) {

      // Only process image files.
      if (!f.type.match('image.*')) {
        continue;
      }

      var reader = new FileReader();

      // Closure to capture the file information.
      reader.onload = (function(theFile) {
        return function(e) {
          // Render thumbnail.
          var span = document.createElement('span');
          span.innerHTML = ['<img class="thumb" src="', e.target.result,
                            '" title="', escape(theFile.name), '"/>'].join('');
          document.getElementById('list').insertBefore(span, null);
        };
      })(f);

      // Read in the image file as a data URL.
      reader.readAsDataURL(f);
    }
  }

  document.getElementById('files').addEventListener('change', handleFileSelect, false);

#list img{
  width: auto;
  height: 100px;
  margin: 10px ;
}

try this

 @Html.DropDownListFor(model => model.UserName, new List<SelectListItem> 
   { new SelectListItem{Text="Active", Value="True",Selected =true },
     new SelectListItem{Text="Deactive", Value="False"}})

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

function wp_get_post_categories( $post_id = 0, $args = array() )
{
   $post_id = (int) $post_id;
   $defaults = array('fields' => 'ids');
   $args = wp_parse_args( $args, $defaults );
   $cats = wp_get_object_terms($post_id, 'category', $args);

   return $cats;
}

Here is the second argument of function wp_get_post_categories() which you can pass the attributes of receiving data.

$category_detail = get_the_category( '4',array( 'fields' => 'names' ) ); //$post->ID
foreach( $category_detail as $cd )
{
   echo $cd->name;
}

From Apple Docs (Swift 3.0.1),

You can simply use a static type property, which is guaranteed to be lazily initialized only once, even when accessed across multiple threads simultaneously:

class Singleton {
    static let sharedInstance = Singleton()
}

If you need to perform additional setup beyond initialization, you can assign the result of the invocation of a closure to the global constant:

class Singleton {
    static let sharedInstance: Singleton = {
        let instance = Singleton()
        // setup code
        return instance
    }()
}

You can use pd.DataFrame.mask with np.isinf. You should ensure first your dataframe series are all of type float. Then use dropna with your existing logic.

print(df)

       col1      col2
0 -0.441406       inf
1 -0.321105      -inf
2 -0.412857  2.223047
3 -0.356610  2.513048

df = df.mask(np.isinf(df))

print(df)

       col1      col2
0 -0.441406       NaN
1 -0.321105       NaN
2 -0.412857  2.223047
3 -0.356610  2.513048

<ToggleButton 
    android:id="@+id/togglebutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textOn="Vibrate on"
    android:textOff="Vibrate off"
    android:onClick="onToggleClicked"/>

Within the Activity that hosts this layout, the following method handles the click event:

public void onToggleClicked(View view) {
    // Is the toggle on?
    boolean on = ((ToggleButton) view).isChecked();

    if (on) {
        // Enable vibrate
    } else {
        // Disable vibrate
    }
}

You can use the code below.

String strFilter = "_id=" + Id;
ContentValues args = new ContentValues();
args.put(KEY_TITLE, title);
myDB.update("titles", args, strFilter, null);

Generally, you'd want to use mail command to send your message using local MTA (that will either deliver it using SMTP to the destination or just forward it into some more powerful SMTP server, for example, at your ISP). If you don't have a local MTA (although it's a bit unusual for a UNIX-like system to omit one), you can either use some minimalistic MTA like ssmtp.

ssmtp is quite easy to configure. Basically, you'll just need to specify where your provider's SMTP server is:

# The place where the mail goes. The actual machine name is required
# no MX records are consulted. Commonly mailhosts are named mail.domain.com
# The example will fit if you are in domain.com and you mailhub is so named.
mailhub=mail

Another option is to use one of myriads scripts that just connect to SMTP server directly and try to post a message there, such as Smtp-Auth-Email-Script, smtp-cli, SendEmail, etc.

In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

>>> 1j
1j
>>> 1J
1j
>>> 1j * 1j
(-1+0j)

The ‘j’ suffix comes from electrical engineering, where the variable ‘i’ is usually used for current. (Reasoning found here.)

The type of a complex number is complex, and you can use the type as a constructor if you prefer:

>>> complex(2,3)
(2+3j)

A complex number has some built-in accessors:

>>> z = 2+3j
>>> z.real
2.0
>>> z.imag
3.0
>>> z.conjugate()
(2-3j)

Several built-in functions support complex numbers:

>>> abs(3 + 4j)
5.0
>>> pow(3 + 4j, 2)
(-7+24j)

The standard module cmath has more functions that handle complex numbers:

>>> import cmath
>>> cmath.sin(2 + 3j)
(9.15449914691143-4.168906959966565j)

And another year later, I can tell you there is another nice answer.

If you don't like the way prototyping works in order to extend on objects/classes, take alook at this: https://github.com/haroldiedema/joii

Quick example code of possibilities (and many more):

var Person = Class({

    username: 'John',
    role: 'Employee',

    __construct: function(name, role) {
        this.username = name;
        this.role = role;
    },

    getNameAndRole: function() {
        return this.username + ' - ' + this.role;
    }

});

var Manager = Class({ extends: Person }, {

  __construct: function(name)
  {
      this.super('__construct', name, 'Manager');
  }

});

var m = new Manager('John');
console.log(m.getNameAndRole()); // Prints: "John - Manager"

It is a conditional statement.

If browser supprts e.keyCode then take e.keyCode else e.charCode.

It is similar to

var code = event.keyCode || event.charCode

event.keyCode: Returns the Unicode value of a non-character key in a keypress event or any key in any other type of keyboard event.

event.charCode: Returns the Unicode value of a character key pressed during a keypress event.

Maybe not the best solution, but it worked for me.

For JavaScript developers, the general rule is as follows:

rxjs: Creation methods, types, schedulers and utilities

import { Observable, Subject, asapScheduler, pipe, of, from, interval, merge, fromEvent } from 'rxjs';

rxjs/operators: All pipeable operators:

import { map, filter, scan } from 'rxjs/operators';

rxjs/webSocket: The web socket subject implementation

import { webSocket } from 'rxjs/webSocket';

rxjs/ajax: The Rx ajax implementation

import { ajax } from 'rxjs/ajax';

rxjs/testing: The testing utilities

import { TestScheduler } from 'rxjs/testing';

and for backward compatability you can use rxjs-compat

OK, so first this is breaking a basic security feature in PowerShell. With that understanding, here is how you can do it:

1. Open an Windows Explorer window
2. Menu Tools -> Folder Options -> tab File Types
3. Find the PS1 file type and click the advanced button
4. Click the New button
5. For Action put: Open
6. For the Application put: "C:\WINNT\system32\WindowsPowerShell\v1.0\powershell.exe" "-file" "%1" %*

You may want to put a -NoProfile argument in there too depending on what your profile does.

Instead of removing all assertions, you should still check for things like a person being his/her own parent or other impossible situations and present an error. Maybe issue a warning if it is unlikely so the user can still detect common input errors, but it will work if everything is correct.

I would store the data in a vector with a permanent integer for each person and store the parents and children in person objects where the said int is the index of the vector. This would be pretty fast to go between generations (but slow for things like name searches). The objects would be in order of when they were created.

Try the following code.

File file = new File(path); // path = your file path
lastSlash = file.toString().lastIndexOf('/');

if (lastSlash >= 0)
{
    fileName = url.toString().substring(lastSlash + 1);
}


if (fileName.endsWith("pdf"))
{
    mimeType = "application/pdf";
}
else
{
    mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension
    (MimeTypeMap.getFileExtensionFromUrl(path));
}

Uri uri_path = Uri.fromFile(file);

Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.putExtra(PATH, path);
intent.putExtra(MIMETYPE, mimeType);
intent.setType(mimeType);
intent.setDataAndType(uri_path, mimeType);

startActivity(intent);

I think the simplest way is just to use the for loop this way:

$codes = array('tn','us','fr');
$names = array('Tunisia','United States','France');

for($i = 0; $i < sizeof($codes); $i++){
    echo '<option value="' . $codes[$i] . '">' . $names[$i] . '</option>';
}

This is valid YAML:

     minSecondaries: 2
     minOplogHours: 100

Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.

Old answer:

Nope, you can't do that in the placeholder attribute. You can't even html encode newlines like 
 in a placeholder.

New answer:

Modern browsers give you several ways to do this. See this JSFiddle:

http://jsfiddle.net/pdXRx/5/

To sum it up:

• There is none in C#.

• You can use the dialog from Visual Basic by adding a reference to Microsoft.VisualBasic:

  1. In Solution Explorer right-click on the References folder.
  2. Select Add Reference...
  3. In the .NET tab (in newer Visual Studio verions - Assembly tab) - select Microsoft.VisualBasic
  4. Click on OK

Then you can use the previously mentioned code:

string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt", "Title", "Default", 0, 0);

• Write your own InputBox.
• Use someone else's.

That said, I suggest that you consider the need of an input box in the first place. Dialogs are not always the best way to do things and sometimes they do more harm than good - but that depends on the particular situation.

Here you go:

^[^<>]*$

This will test for string that has no < and no >

If you want to test for a string that may have < and >, but must also have something other you should use just

[^<>] (or ^.*[^<>].*$)

Where [<>] means any of < or > and [^<>] means any that is not of < or >.

And of course the mandatory link.

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

just change your JDK I installed the JDK of SUN not Oracle and it works for me....

I tend to make my scripts all be relative to one another. That way I can use dirname:

#!/bin/sh

my_dir="$(dirname "$0")"

"$my_dir/other_script.sh"

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex on the row container and at least making sure your middle container on the row has a flex-grow value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow properties applied, middle container only needs 1 for flex-grow).

Here's a pic of what I was trying to do and sample code for how I solved it.

.row {
  background: lightgray;
  height: 30px;
  width: 100%;
  display: flex;
  align-items:flex-end;
  margin-top:5px;
}
.left {
  background:lightblue;
}
.separator{
  flex-grow:1;
  border-bottom:dotted 2px black;
}
.right {
  background:coral;
}

<div class="row">
  <div class="left">Left</div>
  <div class="separator"></div>
  <div class="right">Right With Text</div>
</div>
<div class="row">
  <div class="left">Left With More Text</div>
  <div class="separator"></div>
  <div class="right">Right</div>
</div>
<div class="row">

To detect whether two balls collide, just check whether the distance between their centers is less than two times the radius. To do a perfectly elastic collision between the balls, you only need to worry about the component of the velocity that is in the direction of the collision. The other component (tangent to the collision) will stay the same for both balls. You can get the collision components by creating a unit vector pointing in the direction from one ball to the other, then taking the dot product with the velocity vectors of the balls. You can then plug these components into a 1D perfectly elastic collision equation.

Wikipedia has a pretty good summary of the whole process. For balls of any mass, the new velocities can be calculated using the equations (where v1 and v2 are the velocities after the collision, and u1, u2 are from before):

If the balls have the same mass then the velocities are simply switched. Here's some code I wrote which does something similar:

void Simulation::collide(Storage::Iterator a, Storage::Iterator b)
{
    // Check whether there actually was a collision
    if (a == b)
        return;

    Vector collision = a.position() - b.position();
    double distance = collision.length();
    if (distance == 0.0) {              // hack to avoid div by zero
        collision = Vector(1.0, 0.0);
        distance = 1.0;
    }
    if (distance > 1.0)
        return;

    // Get the components of the velocity vectors which are parallel to the collision.
    // The perpendicular component remains the same for both fish
    collision = collision / distance;
    double aci = a.velocity().dot(collision);
    double bci = b.velocity().dot(collision);

    // Solve for the new velocities using the 1-dimensional elastic collision equations.
    // Turns out it's really simple when the masses are the same.
    double acf = bci;
    double bcf = aci;

    // Replace the collision velocity components with the new ones
    a.velocity() += (acf - aci) * collision;
    b.velocity() += (bcf - bci) * collision;
}

As for efficiency, Ryan Fox is right, you should consider dividing up the region into sections, then doing collision detection within each section. Keep in mind that balls can collide with other balls on the boundaries of a section, so this may make your code much more complicated. Efficiency probably won't matter until you have several hundred balls though. For bonus points, you can run each section on a different core, or split up the processing of collisions within each section.

Using the Promise pattern:

function getImage(url){
        return new Promise(function(resolve, reject){
            var img = new Image()
            img.onload = function(){
                resolve(url)
            }
            img.onerror = function(){
                reject(url)
            }
            img.src = url
        })
    }

And when calling the function we can handle its response or error quite neatly.

getImage('imgUrl').then(function(successUrl){
    //do stufff
}).catch(function(errorUrl){
    //do stuff
})

There's a oneliner for this one.

You can simply run,

docker run -v /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war:/usr/local/tomcat/webapps/myapp.war -it -p 8080:8080 tomcat

This will copy the war file to webapps directory and get your app running in no time.

To solve this you must ensure the following is true on the machine hosting SQL Server...

1. Ensure Server Browser service is running
2. Ensure TCP/IP communication is enabled for each instance you wish to communicate with over the network.
3. If running multiple instances, ensure each instance is using a different port, and that the port is not in use. e.g for two instance 1433 (default port for the default instance, 1435 for a named instance.
4. Ensure the firewall has an entry to allow communication with SQL Server browser on port 1434 over the UDP protocol.
5. Ensure the firewall has an entry to allow communication with SQL Server instances on the ports assigned to them in step 3 over the TCP protocol

There are 2 methods that I can think of to check whether a string has all digits of not

Method 1(Using the built-in isdigit() function in python):-

>>>st = '12345'
>>>st.isdigit()
True
>>>st = '1abcd'
>>>st.isdigit()
False

Method 2(Performing Exception Handling on top of the string):-

st="1abcd"
try:
    number=int(st)
    print("String has all digits in it")
except:
    print("String does not have all digits in it")

The output of the above code will be:

String does not have all digits in it

Create your AlertDialog as usual:

AlertDialog.Builder dialog = new AlertDialog.Builder(getContext());
Dialog dialog = dialog.create();
dialog.show();

After calling show() on your dialog, set the background color like this:

dialog.getWindow().setBackgroundDrawableResource(android.R.color.background_dark);

After wasting a lot of time I finally found this silly mistake which might help you as well.

If you can't return response from your route either through function closure or through controller action then it won't work.

Example:

Closure

Route::post('login', function () {
    return response()->json(['key' => 'value'], 200); //Make sure your response is there.
});

Controller Action

Route::post('login','AuthController@login');

class AuthController extends Controller {

     ...

     public function login() {
          return response()->json(['key' => 'value'], 200); //Make sure your response is there.
     }

     ...

}

Test CORS

Chrome -> Developer Tools -> Network tab

If anything goes wrong then your response headers won't be here.

You could use addEventListener to add as many listeners as you want.

  document.getElementById("Save").addEventListener('click',function ()
    {
     alert("hello");
     //validation code to see State field is mandatory.  
    }  ); 

Also add script tag after the element to make sure Save element is loaded at the time when script runs

Rather than moving script tag you could call it when dom is loaded. Then you should place your code inside the

document.addEventListener('DOMContentLoaded', function() {
    document.getElementById("Save").addEventListener('click',function ()
    {
     alert("hello");
     //validation code to see State field is mandatory.  
    }  ); 
});

example

Basically alter API header response by adding following additional parameters.

Access-Control-Allow-Credentials: true

Access-Control-Allow-Origin: *

But this is not good solution when it comes to the security

public static Map <String, String> parseQueryString (final URL url)
        throws UnsupportedEncodingException
{
    final Map <String, String> qps = new TreeMap <String, String> ();
    final StringTokenizer pairs = new StringTokenizer (url.getQuery (), "&");
    while (pairs.hasMoreTokens ())
    {
        final String pair = pairs.nextToken ();
        final StringTokenizer parts = new StringTokenizer (pair, "=");
        final String name = URLDecoder.decode (parts.nextToken (), "ISO-8859-1");
        final String value = URLDecoder.decode (parts.nextToken (), "ISO-8859-1");
        qps.put (name, value);
    }
    return qps;
}

String res =" Application " res=res.trim();

o/p: Application

Note: White space ,blank space are trim or removed

You can get the values for the width and height of the browser using the following:

$(window).height();
$(window).width();

To get notified when the browser is resized, use this bind callback:

$(window).resize(function() {
    // Do something
});

Keep your private key, public key, known_hosts in same directory and try login as below:

ssh -I(small i) "hi.pem" ec2-user@ec2-**-***-**-***.us-west-2.compute.amazonaws.com

• Same directory in the sense, cd /Users/prince/Desktop. Now type ls command and you should see **.pem **.ppk known_hosts

Note: You have to try to login from the same directory or you'll get a permission denied error as it can't find the .pem file from your present directory.

If you want to be able to SSH from any directory, you can add the following to you ~/.ssh/config file...

Host your.server
HostName ec2-user@ec2-**-***-**-***.us-west-2.compute.amazonaws.com
User ec2-user
IdentityFile ~/.ec2/id_rsa-gsg-keypair
IdentitiesOnly yes

Now you can SSH to your server regardless of where the directory is by simply typing ssh your.server (or whatever name you place after "Host").

Note: In agreement with @epascarello that the better solution is to add a class to the elements and reference that class.

@jk1 answer is perfect, since @igor Ganapolsky asked, why can't we use Mockito.mock here? i post this answer.

For that we have provide one setter method for myobj and set the myobj value with mocked object.

class MyClass {
    MyInterface myObj;

    public void abc() {
        myObj.myMethodToBeVerified (new String("a"), new String("b"));
    }

    public void setMyObj(MyInterface obj)
    {
        this.myObj=obj;
    }
}

In our Test class, we have to write below code

class MyClassTest {

MyClass myClass = new MyClass();

    @Mock
    MyInterface myInterface;

    @test
    testAbc() {
        myclass.setMyObj(myInterface); //it is good to have in @before method
        myClass.abc();
        verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
     }
}

In spring framework provides some special type of annotations,called stereotype annotations. These are following:-

@RestController- Declare at controller level.
@Controller – Declare at controller level.
@Component – Declare at Bean/entity level.
@Repository – Declare at DAO level.
@Service – Declare at BO level.

above declared annotations are special because when we add <context:component-scan> into xxx-servlet.xml file ,spring will automatically create the object of those classes which are annotated with above annotation during context creation/loading phase.

Accept-Language is a list of weighted values (see q parameter). That means just looking at the first language does not mean it’s also the most preferred; in fact, a q value of 0 means not acceptable at all.

So instead of just looking at the first language, parse the list of accepted languages and available languages and find the best match:

// parse list of comma separated language tags and sort it by the quality value
function parseLanguageList($languageList) {
    if (is_null($languageList)) {
        if (!isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
            return array();
        }
        $languageList = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
    }
    $languages = array();
    $languageRanges = explode(',', trim($languageList));
    foreach ($languageRanges as $languageRange) {
        if (preg_match('/(\*|[a-zA-Z0-9]{1,8}(?:-[a-zA-Z0-9]{1,8})*)(?:\s*;\s*q\s*=\s*(0(?:\.\d{0,3})|1(?:\.0{0,3})))?/', trim($languageRange), $match)) {
            if (!isset($match[2])) {
                $match[2] = '1.0';
            } else {
                $match[2] = (string) floatval($match[2]);
            }
            if (!isset($languages[$match[2]])) {
                $languages[$match[2]] = array();
            }
            $languages[$match[2]][] = strtolower($match[1]);
        }
    }
    krsort($languages);
    return $languages;
}

// compare two parsed arrays of language tags and find the matches
function findMatches($accepted, $available) {
    $matches = array();
    $any = false;
    foreach ($accepted as $acceptedQuality => $acceptedValues) {
        $acceptedQuality = floatval($acceptedQuality);
        if ($acceptedQuality === 0.0) continue;
        foreach ($available as $availableQuality => $availableValues) {
            $availableQuality = floatval($availableQuality);
            if ($availableQuality === 0.0) continue;
            foreach ($acceptedValues as $acceptedValue) {
                if ($acceptedValue === '*') {
                    $any = true;
                }
                foreach ($availableValues as $availableValue) {
                    $matchingGrade = matchLanguage($acceptedValue, $availableValue);
                    if ($matchingGrade > 0) {
                        $q = (string) ($acceptedQuality * $availableQuality * $matchingGrade);
                        if (!isset($matches[$q])) {
                            $matches[$q] = array();
                        }
                        if (!in_array($availableValue, $matches[$q])) {
                            $matches[$q][] = $availableValue;
                        }
                    }
                }
            }
        }
    }
    if (count($matches) === 0 && $any) {
        $matches = $available;
    }
    krsort($matches);
    return $matches;
}

// compare two language tags and distinguish the degree of matching
function matchLanguage($a, $b) {
    $a = explode('-', $a);
    $b = explode('-', $b);
    for ($i=0, $n=min(count($a), count($b)); $i<$n; $i++) {
        if ($a[$i] !== $b[$i]) break;
    }
    return $i === 0 ? 0 : (float) $i / count($a);
}

$accepted = parseLanguageList($_SERVER['HTTP_ACCEPT_LANGUAGE']);
var_dump($accepted);
$available = parseLanguageList('en, fr, it');
var_dump($available);
$matches = findMatches($accepted, $available);
var_dump($matches);

If findMatches returns an empty array, no match was found and you can fall back on the default language.

Use below code snippet This worked for me

ObjectMapper objectMapper = new ObjectMapper();
String jsonString = "{\"symbol\":\"ABCD\}";
objectMapper.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);
Trade trade = objectMapper.readValue(jsonString, new TypeReference<Symbol>() {});

@JsonIgnoreProperties    public class Symbol {
    @JsonProperty("symbol")
    private String symbol;

The methods in the Path class are syntactic, meaning that they operate on the Path instance. But eventually you must access the file system to verify that a particular Path exists

 File file = new File("FileName");
 if(file.exists()){
 System.out.println("file is already there");
 }else{
 System.out.println("Not find file ");
 }

The usual method when not using floats is to use display: inline-block: http://www.jsfiddle.net/zygnz/1/

.container div {
  display: inline-block;
}

Do note its limitations though: There is a additional space after the first bloc - this is because the two blocks are now essentially inline elements, like a and em, so whitespace between the two counts. This could break your layout and/or not look nice, and I'd prefer not to strip out all whitespaces between characters for the sake of this working.

Floats are also more flexible, in most cases.

Add a entry, at the end of your enum, called Folders_MAX or something similar and use this value when initializing your arrays.

ContainerClass* m_containers[Folders_MAX];

you can use bc as it can also do floats

var=$(echo "1+2"|bc)

There are a lot of good answers. The key is that you must set nestedScrollingEnabled to false. As mentioned above you can do it in java code:

mRecyclerView.setNestedScrollingEnabled(false);

But also you have an opportunity to set the same property in xml code (android:nestedScrollingEnabled="false"):

 <android.support.v7.widget.RecyclerView
 android:id="@+id/recyclerview"
 android:nestedScrollingEnabled="false"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

if you debug and loook at ctx=null,maybe your username hava proble ,you shoud write like "ac\administrator"(double "\") or "administrator@ac"

1. UNIQUE constraint (of which a PRIMARY KEY constraint is a variant). Checks that all values of a given field are unique across the table. This is X-axis constraint (records)

2. CHECK constraint (of which a NOT NULL constraint is a variant). Checks that a certain condition holds for the expression over the fields of the same record. This is Y-axis constraint (fields)

3. FOREIGN KEY constraint. Checks that a field's value is found among the values of a field in another table. This is Z-axis constraint (tables).

Active is when the user activating that point (Like mouse clicking, if we use tab from field-to-field there is no sign from active style. Maybe clicking need more time, just try hold click on that point), focus is happened after the point is activated. Try this :

<style type="text/css">
  input { font-weight: normal; color: black; }
  input:focus { color: green; outline: 1px solid green; }
  input:active { color: red; outline: 1px solid red; }
</style>

<input type="text"/>

Here use asp:CompareValidator, and compare the value to "select" option.

Use Operator="NotEqual" ValueToCompare="0" to prevent the user from submitting the "select".

<asp:CompareValidator ControlToValidate="ddlReportType" ID="CompareValidator1"
    ValidationGroup="g1" CssClass="errormesg" ErrorMessage="Please select a type"
    runat="server" Display="Dynamic" 
    Operator="NotEqual" ValueToCompare="0" Type="Integer" />

When you do above, if you select the "select " option from dropdown it will show the ErrorMessage.

Try replaceAll() method of the String class.

BTW here is the method, return type and parameters.

public String replaceAll(String regex,
                         String replacement)

Example:

String str = "Hello +-^ my + - friends ^ ^^-- ^^^ +!";
str = str.replaceAll("[-+^]*", "");

It should remove all the {'^', '+', '-'} chars that you wanted to remove!

This will round down correctly as well:

>>> n = 46
>>> rem = n % 10
>>> if rem < 5:
...     n = int(n / 10) * 10
... else:
...     n = int((n + 10) / 10) * 10
...
>>> 50

If you have to display the field on report header then try this... RightClick on Textbox > Properties > Category > date > select *Format (Note this will maintain the regional settings).

Low coupling is in the context of two or many modules. If a change in one module results in many changes in other module then they are said to be highly coupled. This is where interface based programming helps. Any change within the module will not impact the other module as the interface (the mean of interaction ) between them has not changed.

High cohesion- Put the similar things together. So a class should have method or behaviors to do related job. Just to give an exaggerated bad example: An implementation of List interface should not have operation related to String. String class should have methods, fields which is relevant for String and similarly, the implementation of List should have corresponding things.

Hope that helps.

I had this problem. I somehow registered the device for generic team on apple. I don't remember how I did it now. Then I was able to overcome this error.

How to bring back “Browser mode” in IE11?

Easy way to bring back is just go to Emulation (ctrl +8)

and do change user agent string. (see attached image)

What you need is properly a service:

.factory('DataLayer', ['$http',

    function($http) {

        var factory = {};
        var locations;

        factory.getLocations = function(success) {
            if(locations){
                success(locations);
                return;
            }
            $http.get('locations/locations.json').success(function(data) {
                locations = data;
                success(locations);
            });
        };

        return factory;
    }
]);

The locations would be cached in the service which worked as singleton model. This is the right way to fetch data.

Use this service DataLayer in your controller and directive is ok as following:

appControllers.controller('dummyCtrl', function ($scope, DataLayer) {
    DataLayer.getLocations(function(data){
        $scope.locations = data;
    });
});

.directive('map', function(DataLayer) {
    return {
        restrict: 'E',
        replace: true,
        template: '<div></div>',
        link: function(scope, element, attrs) {

            DataLayer.getLocations(function(data) {
                angular.forEach(data, function(location, key){
                    //do something
                });
            });
        }
    };
});

You want to take advantage of the inserted logical table that is available in the context of a trigger. It matches the schema for the table that is being inserted to and includes the row(s) that will be inserted (in an update trigger you have access to the inserted and deleted logical tables which represent the the new and original data respectively.)

So to insert Employee / Department pairs that do not currently exist you might try something like the following.

CREATE TRIGGER trig_Update_Employee
ON [EmployeeResult]
FOR INSERT
AS
Begin
    Insert into Employee (Name, Department) 
    Select Distinct i.Name, i.Department 
    from Inserted i
    Left Join Employee e
    on i.Name = e.Name and i.Department = e.Department
    where e.Name is null
End

http://caniuse.com/#search=::after

::after and ::before with content are better to use as they're supported in every major browser other than Internet Explorer at least 5 versions back. Internet Explorer has complete support in version 9+ and partial support in version 8.

Is this what you're looking for?

.Modal::after{
  content:url('blackCarrot.png'); /* with class ModalCarrot ??*/
  position:relative; /*or absolute*/
  z-index:100000; /*a number that's more than the modal box*/
  left:-50px;
  top:10px;
}

.ModalCarrot{
   position:absolute;
   left:50%;
   margin-left:-8px;
   top:-16px;
}

If not, can you explain a little better?

or you could use jQuery, like Joshua said:

$(".Modal").before("<img src='blackCarrot.png' class='ModalCarrot' />");

Note that there's a weird problem if you're using Bootstrap's JS buttons and the 'loading' state. I don't know why this happens, but here's how to fix it.

Say you have a button and you set it to the loading state:

var myButton = $('#myBootstrapButton');
myButton.button('loading');

Now you want to take it out of the loading state, but also disable it (e.g. the button was a Save button, the loading state indicated an ongoing validation and the validation failed). This looks like reasonable Bootstrap JS:

myButton.button('reset').prop('disabled', true); // DOES NOT WORK

Unfortunately, that will reset the button, but not disable it. Apparently, button() performs some delayed task. So you'll also have to postpone your disabling:

myButton.button('reset');
setTimeout(function() { myButton.prop('disabled', true); }, 0);

A bit annoying, but it's a pattern I'm using a lot.

You can use Eclipse DDMS perspective to see connected devices and browse through files, you can also pull and push files to the device. You can also do a bunch of stuff using DDMS, this link explains a little bit more of DDMS uses.

EDIT:

If you just want to copy a database you can locate the database on eclipse DDMS file explorer, select it and then pull the database from the device to your computer.

Get the real path to your script

if [ -L $0 ] ; then
    ME=$(readlink $0)
else
    ME=$0
fi
DIR=$(dirname $ME)

Numeral.js is a library I created that can can format numbers, currency, percentages and has support for localization.

numeral(0.7523).format('0%') // returns string "75%"

In case you want to utilize .then() which has a subtle difference in comparison with .done() :

return $.post(url, payload)
.then(
    function (result, textStatus, jqXHR) {
        return result;
    },
    function (jqXHR, textStatus, errorThrown) {
        return console.error(errorThrown);
    });

You can create the ordered dict from old dict in one line:

from collections import OrderedDict
ordered_dict = OrderedDict(sorted(ship.items())

The default sorting key is by dictionary key, so the new ordered_dict is sorted by old dict's keys.

Either use window.onload this way

<script>
    window.onload = function() {
        // ...
    }
</script>

or alternatively

<script>
    window.onload = functionName;
</script>

(yes, without the parentheses)

Or just put the script at the very bottom of page, right before </body>. At that point, all HTML DOM elements are ready to be accessed by document functions.

<body>
    ...

    <script>
        functionName();
    </script>
</body>

You can use this code to redirect in php

<?php

This is what has finally served me

/** Set parent scroll to show element
 * @param element {object} The HTML object to show
 * @param parent {object} The HTML object where the element is shown  */
var scrollToView = function(element, parent) {
    //Algorithm: Accumulate the height of the previous elements and add half the height of the parent
    var offsetAccumulator = 0;
    parent = $(parent);
    parent.children().each(function() {
        if(this == element) {
            return false; //brake each loop
        }
        offsetAccumulator += $(this).innerHeight();
    });
    parent.scrollTop(offsetAccumulator - parent.innerHeight()/2);
}

As long as you name your resource bundle files correctly (with a .properties extension), then this works:

File file = new File("C:\\temp");
URL[] urls = {file.toURI().toURL()};
ClassLoader loader = new URLClassLoader(urls);
ResourceBundle rb = ResourceBundle.getBundle("myResource", Locale.getDefault(), loader);

where "c:\temp" is the external folder (NOT on the classpath) holding the property files, and "myResource" relates to myResource.properties, myResource_fr_FR.properties, etc.

This is based off of "default locale"'s answer but it will remove invalid column names prior to setting ordinal. This is because if you accidentally send an invalid column name then it would fail and if you put a check to prevent it from failing then the index would be wrong since it would skip indices wherever an invalid column name was passed in.

public static class DataTableExtensions
{
    /// <summary>
    /// SetOrdinal of DataTable columns based on the index of the columnNames array. Removes invalid column names first.
    /// </summary>
    /// <param name="table"></param>
    /// <param name="columnNames"></param>
    /// <remarks> http://stackoverflow.com/questions/3757997/how-to-change-datatable-colums-order</remarks>
    public static void SetColumnsOrder(this DataTable dtbl, params String[] columnNames)
    {
        List<string> listColNames = columnNames.ToList();

        //Remove invalid column names.
        foreach (string colName in columnNames)
        {
            if (!dtbl.Columns.Contains(colName))
            {
                listColNames.Remove(colName);
            }
        }

        foreach (string colName in listColNames)
        {
            dtbl.Columns[colName].SetOrdinal(listColNames.IndexOf(colName));
        }
}

In Java 8 I would use:

Set<String> set = Stream.of("a", "b").collect(Collectors.toSet());

This gives you a mutable Set pre-initialized with "a" and "b". Note that while in JDK 8 this does return a HashSet, the specification doesn't guarantee it, and this might change in the future. If you specifically want a HashSet, do this instead:

Set<String> set = Stream.of("a", "b")
                        .collect(Collectors.toCollection(HashSet::new));

Having $line as it is now, you can simply split the string based on at least one whitespace separator

my @answer = split(' ', $line); # creates an @answer array

then

print("@answer\n");               # print array on one line

or

print("$_\n") for (@answer);      # print each element on one line

I prefer using () for split, print and for.

Brand new to programming in general and working through an online tutorial. I was asked to do this as well, but only using the methods I had learned so far (basically strings and loops). Not sure if this adds any value here, and I know this isn't how you would do it, but I got it to work with this:

needle = input()
haystack = input()
counter = 0
n=-1
for i in range (n+1,len(haystack)+1):
   for j in range(n+1,len(haystack)+1):
      n=-1
      if needle != haystack[i:j]:
         n = n+1
         continue
      if needle == haystack[i:j]:
         counter = counter + 1
print (counter)

There is a basic difference between .append() and .after() and .prepend() and .before().

.append() adds the parameter element inside the selector element's tag at the very end whereas the .after() adds the parameter element after the element's tag.

The vice-versa is for .prepend() and .before().

This is where the window function row_number() comes in handy:

SELECT s.siteName, s.siteIP, h.date
FROM sites s INNER JOIN
     (select h.*, row_number() over (partition by siteName order by date desc) as seqnum
      from history h
     ) h
    ON s.siteName = h.siteName and seqnum = 1
ORDER BY s.siteName, h.date

I feel I need to clarify one very important thing, for others (like my co-worker) who came across this thread and got the wrong information.

The answer given ("Try decimal(9,2) or decimal(10,2) or whatever.") is correct, but the reason ("increase the number of digits before the decimal") is wrong.

decimal(p,s) and numeric(p,s) both specify a Precision and a Scale. The "precision" is not the number of digits to the left of the decimal, but instead is the total precision of the number.

For example: decimal(2,1) covers 0.0 to 9.9, because the precision is 2 digits (00 to 99) and the scale is 1. decimal(4,1) covers 000.0 to 999.9 decimal(4,2) covers 00.00 to 99.99 decimal(4,3) covers 0.000 to 9.999

If you want to add style in all child and no specification for html tag then use it.

Parent tag div.parent

child tag inside the div.parent like <a>, <input>, <label> etc.

code : div.parent * {color: #045123!important;}

You can also remove important, its not required

An xmlns is a unique identifier within the document - it doesn't have to be a URI to the schema:

XML namespaces provide a simple method for qualifying element and attribute names used in Extensible Markup Language documents by associating them with namespaces identified by URI references.

xsi:schemaLocation is supposed to give a hint as to the actual schema location:

Use __time function:

• ${__time(dd/MM/yyyy,)}

• ${__time(hh:mm a,)}

Since JMeter 3.3, there are two new functions that let you compute a time:

__timeShift

  "The timeShift function returns a date in the given format with the specified amount of seconds, minutes, hours, days or months added" and 

__RandomDate

  "The RandomDate function returns a random date that lies between the given start date and end date values." 

Since JMeter 4.0:

dateTimeConvert

Convert a date or time from source to target format

Personally, I think the "Big Bang" was caused when two GUIDs collided.

Just as @James says, it will order all records, then get the first 20 rows.

As it is so, you are guaranteed to get the 20 first published articles, the newer ones will not be shown.

In your situation, I recommend that you add desc to order by publish_date, if you want the newest articles, then the newest article will be first.

If you need to keep the result in ascending order, and still only want the 10 newest articles you can ask mysql to sort your result two times.

This query below will sort the result descending and limit the result to 10 (that is the query inside the parenthesis). It will still be sorted in descending order, and we are not satisfied with that, so we ask mysql to sort it one more time. Now we have the newest result on the last row.

select t.article 
from 
    (select article, publish_date 
     from table1
     order by publish_date desc limit 10) t 

order by t.publish_date asc;

If you need all columns, it is done this way:

select t.* 
from 
    (select * 
     from table1  
     order by publish_date desc limit 10) t 

order by t.publish_date asc;

I use this technique when I manually write queries to examine the database for various things. I have not used it in a production environment, but now when I bench marked it, the extra sorting does not impact the performance.

For all that you add xmlbeans-2.3.0.jar and it is not working,you must use HSSFWorkbook instead of XSSFWorkbook after add jar.For instance;

    Workbook workbook = new HSSFWorkbook();
    Sheet listSheet = workbook.createSheet("Kisi Listesi");

    int rowIndex = 0;
    for (KayitParam kp : kayitList) {
        Row row = listSheet.createRow(rowIndex++);
        int cellIndex = 0;
        row.createCell(cellIndex++).setCellValue(kp.getAd());
        row.createCell(cellIndex++).setCellValue(kp.getSoyad());
        row.createCell(cellIndex++).setCellValue(kp.getEposta());
        row.createCell(cellIndex++).setCellValue(kp.getCinsiyet());
        row.createCell(cellIndex++).setCellValue(kp.getDogumtarihi());
        row.createCell(cellIndex++).setCellValue(kp.getTahsil());
    }

    try {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        workbook.write(baos);
        AMedia amedia = new AMedia("Kisiler.xls", "xls",
                "application/file", baos.toByteArray());
        Filedownload.save(amedia);
        baos.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

If I have one thing that I love to share with respect to CSS, it's MY FAVE WAY OF CENTERING THINGS ALONG BOTH AXES!!!

Advantages of this method:

1. Full compatibility with browsers that people actually use
2. No tables required
3. Highly reusable for centering any other elements inside their parent
4. Accomodates parents and children with dynamic (changing) dimensions!

I always do this by using 2 classes: One to specify the parent element, whose content will be centered (.centered-wrapper), and the 2nd one to specify which child of the parent is centered (.centered-content). This 2nd class is useful in the case where the parent has multiple children, but only 1 needs to be centered). In this case, body will be the .centered-wrapper, and an inner div will be .centered-content.

<html>
    <head>...</head>
    <body class="centered-wrapper">
        <div class="centered-content">...</div>
    </body>
</html>

The idea for centering will now be to make .centered-content an inline-block. This will easily facilitate horizontal centering, through text-align: center;, and also allows for vertical centering as you shall see.

.centered-wrapper {
    position: relative;
    text-align: center;
}
.centered-wrapper:before {
    content: "";
    position: relative;
    display: inline-block;
    width: 0; height: 100%;
    vertical-align: middle;
}
.centered-content {
    display: inline-block;
    vertical-align: middle;
}

This gives you 2 really reusable classes for centering any child inside of any parent! Just add the .centered-wrapper and .centered-content classes.

So, what's up with that :before element? It facilitates vertical-align: middle; and is necessary because vertical alignment isn't relative to the height of the parent - vertical alignment is relative to the height of the tallest sibling!!!. Therefore, by ensuring that there is a sibling whose height is the parent's height (100% height, 0 width to make it invisible), we know that vertical alignment will be with respect to the parent's height.

One last thing: You need to ensure that your html and body tags are the size of the window so that centering to them is the same as centering to the browser!

html, body {
    width: 100%;
    height: 100%;
    padding: 0;
    margin: 0;
}

Fiddle: https://jsfiddle.net/gershy/g121g72a/

Here is the cleaner solution I wrote based on @Matt suggestion:

function rgb2hex(rgb) {
    rgb = rgb.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
    function hex(x) {
        return ("0" + parseInt(x).toString(16)).slice(-2);
    }
    return "#" + hex(rgb[1]) + hex(rgb[2]) + hex(rgb[3]);
}

Some browsers already returns colors as hexadecimal (as of Internet Explorer 8 and below). If you need to deal with those cases, just append a condition inside the function, like @gfrobenius suggested:

function rgb2hex(rgb) {
    if (/^#[0-9A-F]{6}$/i.test(rgb)) return rgb;

    rgb = rgb.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
    function hex(x) {
        return ("0" + parseInt(x).toString(16)).slice(-2);
    }
    return "#" + hex(rgb[1]) + hex(rgb[2]) + hex(rgb[3]);
}

If you're using jQuery and want a more complete approach, you can use CSS Hooks available since jQuery 1.4.3, as I showed when answering this question: Can I force jQuery.css("backgroundColor") returns on hexadecimal format?

Put this code above any Soap call:

Could write a udf and take a value to tell it which day of the week should be 1 would look like this (drawing on answer from John to use MOD instead of CASE):

DROP FUNCTION IF EXISTS `reporting`.`udfDayOfWeek`;
DELIMITER |
CREATE FUNCTION `reporting`.`udfDayOfWeek` (
  _date DATETIME,
  _firstDay TINYINT
) RETURNS tinyint(4)
FUNCTION_BLOCK: BEGIN
  DECLARE _dayOfWeek, _offset TINYINT;
  SET _offset = 8 - _firstDay;
  SET _dayOfWeek = (DAYOFWEEK(_date) + _offset) MOD 7;
  IF _dayOfWeek = 0 THEN
    SET _dayOfWeek = 7;
  END IF;
  RETURN _dayOfWeek;
END FUNCTION_BLOCK

To call this function to give you the current day of week value when your week starts on a Tuesday for instance, you'd call:

SELECT udfDayOfWeek(NOW(), 3);

Nice thing about having it as a udf is you could also call it on a result set field like this:

SELECT
  udfDayOfWeek(p.SignupDate, 3) AS SignupDayOfWeek,
  p.FirstName,
  p.LastName
FROM Profile p;

Recent versions of bash don't require call to the external program date:

printf -v timestamp '%(%T)T'

%(...)T uses the corresponding argument as a UNIX timestamp, and formats it according to the strftime-style format between the parentheses. An argument of -1 corresponds to the current time, and when no ambiguity would occur can be omitted.

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

+---------------------+
|   <<enumeration>>   |
|    DayOfTheWeek     |
|_____________________|
| Sunday              |
| Monday              |
| Tuesday             |
| ...                 |
+---------------------+

Once it is defined, you can use it as the type of an Attribute just like you would a Datatype or the name one of your own Classes.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

Shortly: gene_name[x] is a mutable object so it cannot be hashed. To use an object as a key in a dictionary, python needs to use its hash value, and that's why you get an error.

Further explanation:

Mutable objects are objects which value can be changed. For example, list is a mutable object, since you can append to it. int is an immutable object, because you can't change it. When you do:

a = 5;
a = 3;

You don't change the value of a, you create a new object and make a point to its value.

Mutable objects cannot be hashed. See this answer.

To solve your problem, you should use immutable objects as keys in your dictionary. For example: tuple, string, int.

You can use crypto-js.

To use crypto-js, you need to load core.js then md5.js .

A list of URLs are here https://cdnjs.com/libraries/crypto-js

cryptojs is also available in zip form here https://code.google.com/archive/p/crypto-js/downloads

There is an answer from answerer 'amal' in 2013, that is similar to this but a)his link to md5.js no longer works b)he didn't load core.js beforehand, which is necessary.

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")

java.time

The java.time framework built into Java 8 and later supplants both the old date-time classes bundled with the earliest versions of Java and the Joda-Time library. The java.time classes have been back-ported to Java 6 & 7 and to Android.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = Instant.now();

Apply an offset-from-UTC (a number of hours and possible minutes and seconds) to get an OffsetDateTime.

ZoneOffset offset = ZoneOffset.of( "-04:00" );
OffsetDateTime odt = OffsetDateTime.ofInstant( instant , offset );

Better yet is applying a full time zone which is an offset plus a set of rules for handling anomalies such as Daylight Saving Time (DST).

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Database

Hopefully the JDBC drivers will be updated to work directly with the java.time classes. Until then we must use the java.sql classes to move date-time values to/from the database. But limit your use of the java.sql classes to the chore of database transit. Do not use them for business logic. As part of the old date-time classes they are poorly designed, confusing, and troublesome.

Use new methods added to the old classes to convert to/from java.time. Look for to… and valueOf methods.

Use the java.sql.Timestamp class for date-time values.

java.sql.Timestamp ts = java.sql.Timestamp.valueOf( instant );

And going the other direction…

Instant instant = ts.toInstant();

For date-time data you virtually always want the TIMESTAMP WITH TIME ZONE data type rather than WITHOUT when designing your table columns in your database.

@GaryK answer is absolutely great, I've spent an hour looking for an explanation orphanRemoval = true vs CascadeType.REMOVE and it helped me understand.

Summing up: orphanRemoval = true works identical as CascadeType.REMOVE ONLY IF we deleting object (entityManager.delete(object)) and we want the childs objects to be removed as well.

In completely different sitiuation, when we fetching some data like List<Child> childs = object.getChilds() and then remove a child (entityManager.remove(childs.get(0)) using orphanRemoval=true will cause that entity corresponding to childs.get(0) will be deleted from database.

To break down the error message:

Unable to resolve service for type 'WebApplication1.Data.BloggerRepository' while attempting to activate 'WebApplication1.Controllers.BlogController'.

That is saying that your application is trying to create an instance of BlogController but it doesn't know how to create an instance of BloggerRepository to pass into the constructor.

Now look at your startup:

services.AddScoped<IBloggerRepository, BloggerRepository>();

That is saying whenever a IBloggerRepository is required, create a BloggerRepository and pass that in.

However, your controller class is asking for the concrete class BloggerRepository and the dependency injection container doesn't know what to do when asked for that directly.

I'm guessing you just made a typo, but a fairly common one. So the simple fix is to change your controller to accept something that the DI container does know how to process, in this case, the interface:

public BlogController(IBloggerRepository repository)
//                    ^
//                    Add this!
{
    _repository = repository;
}

This might work:

public int binaryToInteger(String binary) {
    char[] numbers = binary.toCharArray();
    int result = 0;
    for(int i=numbers.length - 1; i>=0; i--)
        if(numbers[i]=='1')
            result += Math.pow(2, (numbers.length-i - 1));
    return result;
}

list is mutable

Change

last_list=last_list.append(p.last_name)

to

last_list.append(p.last_name)

will work

For swift 4 and you can adjust imageView size

 let logoContainer = UIView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))

 let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))
 imageView.contentMode = .scaleAspectFit
 let image = UIImage(named: "your_image")
 imageView.image = image
 logoContainer.addSubview(imageView)
 navigationItem.titleView = logoContainer

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

I find this to be the bane of XML style document commenting too. There are XML editors like eclipse that can perform block commenting. Basically automatically add extra per line and remove them. May be they made it purposefully hard to comment that style of document it was supposed to be self explanatory with the tags after all.

In a .txt file opened with Notepad++,
press Ctrl-F
go in the tab "Replace"
write the regex pattern \|.+ in the space Find what
and let the space Replace with blank

Then tick the choice matches newlines after the choice Regular expression
and press two times on the Replace button

Maybe this will help.

var inputVal = $(this).closest('tr').find("td:eq(x) input").val();

The Date constructor in JavaScript needs a string in one of the date formats supported by the parse() method.

Apparently, the format you are specifying isn't supported in IE, so you'll need to either change the PHP code, or parse the string manually in JavaScript.

This is what I use. Just keep removing space from the front, and then, if there's anything left, do the same from the back.

void trim(string& s) {
    while(s.compare(0,1," ")==0)
        s.erase(s.begin()); // remove leading whitespaces
    while(s.size()>0 && s.compare(s.size()-1,1," ")==0)
        s.erase(s.end()-1); // remove trailing whitespaces
}

Here is a static class implementing Start(), Stop(), and IsStarted() for IISExpress. It is parametrized by hard-coded static properties and passes invocation information via the command-line arguments to IISExpress. It uses the Nuget package, MissingLinq.Linq2Management, which surprisingly provides information missing from System.Diagnostics.Process, specifically, the command-line arguments that can then be used to help disambiguate possible multiple instances of IISExpress processes, since I don't preserve the process Ids. I presume there is a way to accomplish the same thing with just System.Diagnostics.Process, but life is short. Enjoy.

Write the following method:

public boolean isAlertPresent() {
    try {
        driver.switchTo().alert();
        return true;
    } // try
    catch (Exception e) {
        return false;
    } // catch
}

Now, you can check whether alert is present or not by using the method written above as below:

if (isAlertPresent()) {
    driver.switchTo().alert();
    driver.switchTo().alert().accept();
    driver.switchTo().defaultContent();
}

Try this:

select * from your_table
where date >= '2020-10-01'  

<div class="row">
  <div class="col-4 alert alert-primary">
     1
  </div>
  <div class="col-8">
    <div class="row">
      <div class="col-6 alert alert-primary">
        2
      </div>
      <div class="col-6 alert alert-primary">
        3
      </div>
      <div class="col-6 alert alert-primary">
        4
      </div>
      <div class="col-6 alert alert-primary">
        5
      </div>
    </div>
  </div>
</div>
<div class="row">
  <div class="col-4 alert alert-primary">
    6
  </div>
  <div class="col-4 alert alert-primary">

  </div>
  <div class="col-4 alert alert-primary">

I know that this is a old question. But I think I have a good solution.

$date = "2016-02-21";
$format = "Y-m-d";

if(date($format, strtotime($date)) == date($date)) {
    echo "true";
} else {
    echo "false";
}

You can try it. If you change the date to 21.02.2016 the echo is false. And if you change the format after that to d.m.Y the echo is true.

With this easy code you should be able to check which date-format is used without checking it by the regex.

Maybe there is a person who will test it on every case. But I think my idea is generally valid. For me it seems logical.

The below code helps to get the details of elements from the specific form with the form id,

$('#formId input, #formId select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements from all the forms which are place in the loading page,

$('form input, form select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements which are place in the loading page even when the element is not place inside the tag,

$('input, select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

NOTE: We add the more element tag name what we need in the object list like as below,

Example: to get name of attribute "textarea",

$('input, select, textarea').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);
