In your JSON format, it do not have starting JSON object

Like :

{
    "info" :       <!-- this is starting JSON object -->
        {
        "caller":"getPoiById",
        "results":
        {
            "indexForPhone":0,
            "indexForEmail":"NULL",
            .
            .
         }
    }
}

Above Json starts with info as JSON object. So while executing :

JSONObject json = new JSONObject(result);    // create JSON obj from string
JSONObject json2 = json.getJSONObject("info");    // this will return correct

Now, we can access result field :

JSONObject jsonResult = json2.getJSONObject("results");
test = json2.getString("name"); // returns "Marina Rasche Werft GmbH & Co. KG"

I think this was missing and so the problem was solved while we use JSONTokener like answer of yours.

Your answer is very fine. Just i think i add this information so i answered

Thank you

Grouped Array of Object in typescript with this:

groupBy (list: any[], key: string): Map<string, Array<any>> {
    let map = new Map();
    list.map(val=> {
        if(!map.has(val[key])){
            map.set(val[key],list.filter(data => data[key] == val[key]));
        }
    });
    return map;
});

Below Bash Script Deletes all the tags located in registry except the latest.

for D in /registry-data/docker/registry/v2/repositories/*; do
if [ -d "${D}" ]; then
    if [ -z "$(ls -A ${D}/_manifests/tags/)" ]; then
        echo ''
    else
        for R in $(ls -t ${D}/_manifests/tags/ | tail -n +2); do
            digest=$(curl -k -I -s -H -X GET http://xx.xx.xx.xx:5000/v2/$(basename  ${D})/manifests/${R} -H 'accept: application/vnd.docker.distribution.manifest.v2+json'  | grep Docker-Content-Digest | awk '{print $2}' )
            url="http://xx.xx.xx.xx:5000/v2/$(basename  ${D})/manifests/$digest"

After this Run

docker exec $(docker ps | grep registry | awk '{print $1}') /bin/registry garbage-collect /etc/docker/registry/config.yml

You can try to apply new architecture approach anounced at Google I/O 2017.

It also includes new ORM library called Room

It contains three main components: @Entity, @Dao and @Database

User.java

@Entity
public class User {
  @PrimaryKey
  private int uid;

  @ColumnInfo(name = "first_name")
  private String firstName;

  @ColumnInfo(name = "last_name")
  private String lastName;

  // Getters and setters are ignored for brevity,
  // but they're required for Room to work.
}

UserDao.java

@Dao
public interface UserDao {
  @Query("SELECT * FROM user")
  List<User> getAll();

  @Query("SELECT * FROM user WHERE uid IN (:userIds)")
  List<User> loadAllByIds(int[] userIds);

  @Query("SELECT * FROM user WHERE first_name LIKE :first AND "
       + "last_name LIKE :last LIMIT 1")
  User findByName(String first, String last);

  @Insert
  void insertAll(User... users);

  @Delete
  void delete(User user);
}

AppDatabase.java

@Database(entities = {User.class}, version = 1)
public abstract class AppDatabase extends RoomDatabase {
  public abstract UserDao userDao();
}

You can use the PHP printf or sprintf functions:

Example with sprintf:

$num = 2.12;
echo sprintf("%.3f", $num);

You can run the same without echo as well. Example: sprintf("%.3f", $num);

Output:

2.120

Alternatively, with printf:

echo printf("%.2f", $num);

Output:

2.124

You won't be able to restore from 2012 to 2008. You will be able to use a tool like red-gate SQL compare to copy the schema etc (provided nothing 2012 specific is used). If you have data to copy across too, you can use their Data Compare tool, and I think you get a 14 day free trial.

If you have Excel 2010 you can copy your data into another column, than select it and choose Data -> Remove Duplicates. You can then write =COUNTIF($A$1:$A$100,B1) next to it and copy the formula down. This assumes you have your values in range A1:A100 and the de-duplicated values are in column B.

We don't talk about iTextSharp anymore. You are using iText 5 for .NET. The current version is iText 7 for .NET.

Obsolete answer:

The AddHeader has been deprecated a long time ago and has been removed from iTextSharp. Adding headers and footers is now done using page events. The examples are in Java, but you can find the C# port of the examples here and here (scroll to the bottom of the page for links to the .cs files).

Make sure you read the documentation. A common mistake by many developers have made before you, is adding content in the OnStartPage. You should only add content in the OnEndPage. It's also obvious that you need to add the content at absolute coordinates (for instance using ColumnText) and that you need to reserve sufficient space for the header and footer by defining the margins of your document correctly.

Updated answer:

If you are new to iText, you should use iText 7 and use event handlers to add headers and footers. See chapter 3 of the iText 7 Jump-Start Tutorial for .NET.

When you have a PdfDocument in iText 7, you can add an event handler:

PdfDocument pdf = new PdfDocument(new PdfWriter(dest));
pdf.addEventHandler(PdfDocumentEvent.END_PAGE, new MyEventHandler());

This is an example of the hard way to add text at an absolute position (using PdfCanvas):

protected internal class MyEventHandler : IEventHandler {
    public virtual void HandleEvent(Event @event) {
        PdfDocumentEvent docEvent = (PdfDocumentEvent)@event;
        PdfDocument pdfDoc = docEvent.GetDocument();
        PdfPage page = docEvent.GetPage();
        int pageNumber = pdfDoc.GetPageNumber(page);
        Rectangle pageSize = page.GetPageSize();
        PdfCanvas pdfCanvas = new PdfCanvas(page.NewContentStreamBefore(), page.GetResources(), pdfDoc);
        //Add header
        pdfCanvas.BeginText()
            .SetFontAndSize(C03E03_UFO.helvetica, 9)
            .MoveText(pageSize.GetWidth() / 2 - 60, pageSize.GetTop() - 20)
            .ShowText("THE TRUTH IS OUT THERE")
            .MoveText(60, -pageSize.GetTop() + 30)
            .ShowText(pageNumber.ToString())
            .EndText();
        pdfCanvas.release();
    }
}

This is a slightly higher-level way, using Canvas:

protected internal class MyEventHandler : IEventHandler {
    public virtual void HandleEvent(Event @event) {
        PdfDocumentEvent docEvent = (PdfDocumentEvent)@event;
        PdfDocument pdfDoc = docEvent.GetDocument();
        PdfPage page = docEvent.GetPage();
        int pageNumber = pdfDoc.GetPageNumber(page);
        Rectangle pageSize = page.GetPageSize();
        PdfCanvas pdfCanvas = new PdfCanvas(page.NewContentStreamBefore(), page.GetResources(), pdfDoc);
        //Add watermark
        Canvas canvas = new Canvas(pdfCanvas, pdfDoc, page.getPageSize());
        canvas.setFontColor(Color.WHITE);
        canvas.setProperty(Property.FONT_SIZE, 60);
        canvas.setProperty(Property.FONT, helveticaBold);
        canvas.showTextAligned(new Paragraph("CONFIDENTIAL"),
            298, 421, pdfDoc.getPageNumber(page),
            TextAlignment.CENTER, VerticalAlignment.MIDDLE, 45);
        pdfCanvas.release();
    }
}

There are other ways to add content at absolute positions. They are described in the different iText books.

I've continued to research this item myself, and it does appear to remain beyond us at this point.

I even tried buying a Apple Composite AV Cable, but it doesn't capture screen, just video playing like YouTube, etc.

So I decided to go with the iShowU path and that has worked out well so far.

Thanks Guys!

You are making a request to external domain 172.16.1.157:8002/ from your local development server that is why it is giving cross origin exception. Either you have to allow headers Access-Control-Allow-Origin:* in both frontend and backend or alternatively use this extension cors header toggle - chrome extension unless you host backend and frontend on the same domain.

TL;DR

Use one of these for universal conversion needs

//Java 7 or below
bigDecimal.setScale(0, RoundingMode.DOWN).intValueExact()
//Java 8    
bigDecimal.toBigInteger().intValueExact()

Reasoning

The answer depends on what the requirements are and how you answer these question.

• Will the BigDecimal potentially have a non-zero fractional part?
• Will the BigDecimal potentially not fit into the Integer range?
• Would you like non-zero fractional parts rounded or truncated?
• How would you like non-zero fractional parts rounded?

If you answered no to the first 2 questions, you could just use BigDecimal.intValueExact() as others have suggested and let it blow up when something unexpected happens.

If you are not absolutely 100% confident about question number 2, then intValue() is always the wrong answer.

Making it better

Let's use the following assumptions based on the other answers.

• We are okay with losing precision and truncating the value because that's what intValueExact() and auto-boxing do
• We want an exception thrown when the BigDecimal is larger than the Integer range because anything else would be crazy unless you have a very specific need for the wrap around that happens when you drop the high-order bits.

Given those params, intValueExact() throws an exception when we don't want it to if our fractional part is non-zero. On the other hand, intValue() doesn't throw an exception when it should if our BigDecimal is too large.

To get the best of both worlds, round off the BigDecimal first, then convert. This also has the benefit of giving you more control over the rounding process.

Spock Groovy Test

void 'test BigDecimal rounding'() {
    given:
    BigDecimal decimal = new BigDecimal(Integer.MAX_VALUE - 1.99)
    BigDecimal hugeDecimal = new BigDecimal(Integer.MAX_VALUE + 1.99)
    BigDecimal reallyHuge = new BigDecimal("10000000000000000000000000000000000000000000000")
    String decimalAsBigIntString = decimal.toBigInteger().toString()
    String hugeDecimalAsBigIntString = hugeDecimal.toBigInteger().toString()
    String reallyHugeAsBigIntString = reallyHuge.toBigInteger().toString()

    expect: 'decimals that can be truncated within Integer range to do so without exception'
    //GOOD: Truncates without exception
    '' + decimal.intValue() == decimalAsBigIntString
    //BAD: Throws ArithmeticException 'Non-zero decimal digits' because we lose information
    // decimal.intValueExact() == decimalAsBigIntString
    //GOOD: Truncates without exception
    '' + decimal.setScale(0, RoundingMode.DOWN).intValueExact() == decimalAsBigIntString

    and: 'truncated decimal that cannot be truncated within Integer range throw conversionOverflow exception'
    //BAD: hugeDecimal.intValue() is -2147483648 instead of 2147483648
    //'' + hugeDecimal.intValue() == hugeDecimalAsBigIntString
    //BAD: Throws ArithmeticException 'Non-zero decimal digits' because we lose information
    //'' + hugeDecimal.intValueExact() == hugeDecimalAsBigIntString
    //GOOD: Throws conversionOverflow ArithmeticException because to large
    //'' + hugeDecimal.setScale(0, RoundingMode.DOWN).intValueExact() == hugeDecimalAsBigIntString

    and: 'truncated decimal that cannot be truncated within Integer range throw conversionOverflow exception'
    //BAD: hugeDecimal.intValue() is 0
    //'' + reallyHuge.intValue() == reallyHugeAsBigIntString
    //GOOD: Throws conversionOverflow ArithmeticException because to large
    //'' + reallyHuge.intValueExact() == reallyHugeAsBigIntString
    //GOOD: Throws conversionOverflow ArithmeticException because to large
    //'' + reallyHuge.setScale(0, RoundingMode.DOWN).intValueExact() == reallyHugeAsBigIntString

    and: 'if using Java 8, BigInteger has intValueExact() just like BigDecimal'
    //decimal.toBigInteger().intValueExact() == decimal.setScale(0, RoundingMode.DOWN).intValueExact()
}

If I put stdlib.h or stdio.h, I don't have to link those but I have to link when I compile:

stdlib.h, stdio.h are the header files. You include them for your convenience. They only forecast what symbols will become available if you link in the proper library. The implementations are in the library files, that's where the functions really live.

Including math.h is only the first step to gaining access to all the math functions.

Also, you don't have to link against libm if you don't use it's functions, even if you do a #include <math.h> which is only an informational step for you, for the compiler about the symbols.

stdlib.h, stdio.h refer to functions available in libc, which happens to be always linked in so that the user doesn't have to do it himself.

I created a small helper method to wait for a few Threads to finish:

public static void waitForThreadsToFinish(Thread... threads) {
        try {
            for (Thread thread : threads) {
                thread.join();
            }
        }
        catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

Padding around the collapsing div must be 0

There's an easier way, by extending an empty LatLngBounds rather than creating one explicitly from two points. (See this question for more details)

Should look something like this, added to your code:

//create empty LatLngBounds object
var bounds = new google.maps.LatLngBounds();
var infowindow = new google.maps.InfoWindow();    

for (i = 0; i < locations.length; i++) {  
  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map
  });

  //extend the bounds to include each marker's position
  bounds.extend(marker.position);

  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infowindow.setContent(locations[i][0]);
      infowindow.open(map, marker);
    }
  })(marker, i));
}

//now fit the map to the newly inclusive bounds
map.fitBounds(bounds);

//(optional) restore the zoom level after the map is done scaling
var listener = google.maps.event.addListener(map, "idle", function () {
    map.setZoom(3);
    google.maps.event.removeListener(listener);
});

This way, you can use an arbitrary number of points, and don't need to know the order beforehand.

Demo jsFiddle here: http://jsfiddle.net/x5R63/

If you are looking for only one object to be removed, you can use

Person.findOne({_id: req.params.id}, function (error, person){
        console.log("This object will get deleted " + person);
        person.remove();

    });

In this example, Mongoose will delete based on matching req.params.id.

Add relative positioning to the wrapping div tag, then absolutely position the image within it like this:

CSS:

.div-wrapper {
    position: relative;
    height: 300px;
    width: 300px;
}

.div-wrapper img {
    position: absolute;
    left: 0;
    bottom: 0;
}

HTML:

<div class="div-wrapper">
    <img src="blah.png"/>
</div>

Now the image sits at the bottom of the div.

Write this code in Terminal.

export GOPATH=path/to/your/gopath/directory

Note: This will reset on every new Terminal window or system restart.

To be persistent, paste the code below in your .zshrc or .bashrc file according to your shell. Those files in your Home Directory. It will be like below.

export PATH=path/to/some/other/place/composer/for/example
export GOPATH=path/to/your/gopath/directory
export PATH=$PATH:$GOPATH/bin

DateFormatSymbols class provides methods for our ease use.

To get short month strings. For example: "Jan", "Feb", etc.

getShortMonths()

To get month strings. For example: "January", "February", etc.

getMonths()

Sample code to return month string in mmm format,

private static String getShortMonthFromNumber(int month){
    if(month<0 || month>11){
        return "";
    }
    return new DateFormatSymbols().getShortMonths()[month];
}

You Can Use FORMAT if you column is a number Syntax like FORMAT ( value, format [, culture ] ) In use like FORMAT ( @d, 'D', 'en-US' ) or FORMAT(123456789,'###-##-####') (But This works for only SQL SERVER 2012 And After)

In Use Like UPDATE TABLE_NAME SET COLUMN_NAME = FORMAT(COLUMN_NAME ,'###-##-####')

And

if your column is Varchar Or Nvarchar use do like this CONCAT(SUBSTRING(CELLPHONE,0,4),' ',SUBSTRING(CELLPHONE,4,3),' ',SUBSTRING(CELLPHONE,7,2) ,' ',SUBSTRING(CELLPHONE,9,2) )

You can always get help from

There are two ways to resolve this, and only one may work, depending on how you're accessing Google.

The first method is to authorize access for your IP or client machine using the https://accounts.google.com/DisplayUnlockCaptcha link. That can resolve authentication issues on client devices, like mobile or desktop apps. I would test this first, because it results in a lower overall decrease in account security.

If the above link doesn't work, it's because the session is being initiated by an app or device that is not associated with your particular location. Examples include:

• An app that uses a remote server to retrieve data, like a web site or, in my case, other Google servers
• A company mail server fetching mail on your behalf

In all such cases you have to use the https://www.google.com/settings/security/lesssecureapps link referenced above.

TLDR; check the captcha link first, and if it doesn't work, try the other one and enable less secure apps.

If you read the docs.

$('#mydialog').dialog('isOpen')

This method returns a Boolean (true or false), not a jQuery object.

Yield return can be very powerful for algorithms where you need to iterate through millions of objects. Consider the following example where you need to calculate possible trips for ride sharing. First we generate possible trips:

    static IEnumerable<Trip> CreatePossibleTrips()
    {
        for (int i = 0; i < 1000000; i++)
        {
            yield return new Trip
            {
                Id = i.ToString(),
                Driver = new Driver { Id = i.ToString() }
            };
        }
    }

Then iterate through each trip:

    static void Main(string[] args)
    {
        foreach (var trip in CreatePossibleTrips())
        {
            // possible trip is actually calculated only at this point, because of yield
            if (IsTripGood(trip))
            {
                // match good trip
            }
        }
    }

If you use List instead of yield, you will need to allocation 1 million objects to memory (~190mb) and this simple example will take ~1400ms to run. However, if you use yield, you don't need to put all these temp objects to memory and you will get significantly faster algorithm speed: this example will take only ~400ms to run with no memory consumption at all.

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

Th easiest way to this is var id = $(this).val(); from inside an event like on change.

on delete button click event

public void delete(View v){                

    ListView listview1;
    ArrayList<E> datalist;

    final int position = listview1.getPositionForView((View) v.getParent());
    datalist.remove(position);
    myAdapter.notifyDataSetChanged();

}

document.getElementById('id').value

You can do this assignment easily by using jquery. In this way, you can define number of row limitation. Furthermore, you can regular breakpoints height that want adding vertical scrolling. I must say that more than 3 rows get modify class and also height is 76px.

class Dog(object):

    # Class Object Attribute
    species = 'mammal'

    def __init__(self,breed,name):
        self.breed = breed
        self.name = name

In above example we use species as a global since it will be always same(Kind of constant you can say). when you call __init__ method then all the variable inside __init__ will be initiated(eg:breed,name).

class Dog(object):
    a = '12'

    def __init__(self,breed,name,a):
        self.breed = breed
        self.name = name
        self.a= a

if you print the above example by calling below like this

Dog.a
12

Dog('Lab','Sam','10')
Dog.a
10

That means it will be only initialized during object creation. so anything which you want to declare as constant make it as global and anything which changes use __init__

In my case:

const navigationExtras: NavigationExtras = {
    queryParams: { 'param': val }
};

this.router.navigate([], navigationExtras);

work correct

I was getting this error:

So, I went to Tools -> SDK Manager -> SDK Tools. Then I installed Google Play Licensing Library. It solved the problem.

// Or on the init
$( ".selector" ).datepicker({ defaultDate: 15 });

jQuery ui docs

All these keywords try, catch and throw are related to the exception handling concept in java. An exception is an event that occurs during the execution of programs. Exception disrupts the normal flow of an application. Exception handling is a mechanism used to handle the exception so that the normal flow of application can be maintained. Try-catch block is used to handle the exception. In a try block, we write the code which may throw an exception and in catch block we write code to handle that exception. Throw keyword is used to explicitly throw an exception. Generally, throw keyword is used to throw user defined exceptions.

Just for an addition reference to the above answers. I can not use dpkg -L to find the correct path for cuda. See the results I got from dpkg -L

$ dpkg -L cuda
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/cuda
/usr/share/doc/cuda/copyright
/usr/share/doc/cuda/changelog.Debian.gz

the correct path is /usr/local/cuda

$ ll /usr/local | grep cuda

lrwxrwxrwx  1 root root    8 Oct 20 18:45 cuda -> cuda-9.0/

drwxr-xr-x 15 root root 4096 Oct 20 18:44 cuda-9.0/

Btw, I did install cuda by the command of

dpkg -i xx_cuda_xxx.deb

echo array_search("car",array_keys($a));

Your code should read -

String kk = wd.findElement(By.cssSelector("div[id^='customSelect'] span.selectLabel")).getText();

Use CSS. it's much cleaner and easier.. Let me know if that solves your issue.

Woff is a compressed (zipped) form of the TrueType - OpenType font. It is small and can be delivered over the network like a graphic file. Most importantly, this way the font is preserved completely including rendering rule tables that very few people care about because they use only Latin script.

Take a look at [dead URL removed]. The font you see is an experimental web delivered smartfont (woff) that has thousands of combined characters making complex shapes. The underlying text is simple Latin code of romanized Singhala. (Copy and paste to Notepad and see).

Only woff can do this because nobody has this font and yet it is seen anywhere (Mac, Win, Linux and even on smartphones by all browsers except by IE. IE does not have full support for Open Types).

$array = explode('.',$string);

Are you missing a function declaration?

void ac_search(uint num_patterns, uint pattern_length, const char *patterns, 
               uint num_records, uint record_length, const char *records, int *matches, Node* trie);

Add it just before your implementation of ac_benchmark_search.

If you are not using the assembly directly in code then Visual Studio whilst trying to be helpful detects that it is not used and doesn't include it in the output. I'm not sure why you are seeing different behaviour between Visual Studio and MSBuild. You could try setting the build output to diagnostic for both and compare the results see where it diverges.

As for your elmah.dll reference if you are not referencing it directly in code you could add it as an item to your project and set the Build Action to Content and the Copy to Output Directory to Always.

You can use jQuery change() function

$('input').change(function(){
  //your codes
});

There are examples on how to use it on the API Page: http://api.jquery.com/change/

Seems your resource POSTmethod won't get hit as @peeskillet mention. Most probably your ~POST~ request won't work, because it may not be a simple request. The only simple requests are GET, HEAD or POST and request headers are simple(The only simple headers are Accept, Accept-Language, Content-Language, Content-Type= application/x-www-form-urlencoded, multipart/form-data, text/plain).

Since in you already add Access-Control-Allow-Origin headers to your Response, you can add new OPTIONS method to your resource class.

    @OPTIONS
@Path("{path : .*}")
public Response options() {
    return Response.ok("")
            .header("Access-Control-Allow-Origin", "*")
            .header("Access-Control-Allow-Headers", "origin, content-type, accept, authorization")
            .header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD")
            .header("Access-Control-Max-Age", "2000")
            .build();
}

git diff branch_1..branch_2

That will produce the diff between the tips of the two branches. If you'd prefer to find the diff from their common ancestor to test, you can use three dots instead of two:

git diff branch_1...branch_2

For those using bootstrap 4 beta you can add max-width on your navbar link to have control on the size of your logo with img-fluid class on the image element.

 <a class="navbar-brand" href="#" style="max-width: 30%;">

in React v16.8+ function component, you can use useState() to create a function state that lets you update the parent state, then pass it on to child as a props attribute, then inside the child component you can trigger the parent state function, the following is a working snippet:

const { useState , useEffect } = React;_x000D_
_x000D_
function Timer({ setParentCounter }) {_x000D_
  const [counter, setCounter] = React.useState(0);_x000D_

  useEffect(() => {_x000D_
    let countersystem;_x000D_
    countersystem = setTimeout(() => setCounter(counter + 1), 1000);_x000D_
_x000D_
    return () => {_x000D_
      clearTimeout(countersystem);_x000D_

In Bash, these are bound to Esc-B and Esc-F. Bash has many, many more keyboard shortcuts; have a look at the output of bind -p to see what they are.

if you know for sure that there are only going to be 2 places where you have a list of digits in your string and that is the only thing you are going to pull out then you should be able to simply use

\d+

From the title of this question I was expecting to find something like range(), that would let me specify two dates and create a list with all the dates in between. That way one does not need to calculate the number of days between those two dates, if one does not know it beforehand.

So with the risk of being slightly off-topic, this one-liner does the job:

import datetime
start_date = datetime.date(2011, 01, 01)
end_date   = datetime.date(2014, 01, 01)

dates_2011_2013 = [ start_date + datetime.timedelta(n) for n in range(int ((end_date - start_date).days))]

NOTE: history.pushState() is now supported - see other answers.

You cannot change the whole url without redirecting, what you can do instead is change the hash.

The hash is the part of the url that goes after the # symbol. That was initially intended to direct you (locally) to sections of your HTML document, but you can read and modify it through javascript to use it somewhat like a global variable.

If applied well, this technique is useful in two ways:

1. the browser history will remember each different step you took (since the url+hash changed)
2. you can have an address which links not only to a particular html document, but also gives your javascript a clue about what to do. That means you end up pointing to a state inside your web app.

To change the hash you can do:

document.location.hash = "show_picture";

To watch for hash changes you have to do something like:

window.onhashchange = function(){
    var what_to_do = document.location.hash;    
    if (what_to_do=="#show_picture")
        show_picture();
}

Of course the hash is just a string, so you can do pretty much what you like with it. For example you can put a whole object there if you use JSON to stringify it.

There are very good JQuery libraries to do advanced things with that.

things that speed up the inserts:

• i had removed all keys from a table before large insert into empty table
• then found i had a problem that the index did not fit in memory.
• also found i had sync_binlog=0 (should be 1) even if binlog is not used.
• also found i did not set innodb_buffer_pool_instances

Unit test: testing of an individual module or independent component in an application is known to be unit testing. The unit testing will be done by the developer.

Integration test: combining all the modules and testing the application to verify the communication and the data flow between the modules are working properly or not. This testing also performed by developers.

Smoke test In a smoke test they check the application in a shallow and wide manner. In smoke testing they check the main functionality of the application. If there is any blocker issue in the application they will report to developer team, and the developing team will fix it and rectify the defect, and give it back to the testing team. Now testing team will check all the modules to verify that changes made in one module will impact the other module or not. In smoke testing the test cases are scripted.

Regression testing executing the same test cases repeatedly to ensure tat the unchanged module does not cause any defect. Regression testting comes under functional testing

If you always add to the end, then each element will be added to the end and stay that way until you change it.

If you always insert at the start, then each element will appear in the reverse order you added them.

If you insert them in the middle, the order will be something else.

Depending on the use case, you might also want to disable the buffering in the subprocess itself.

If the subprocess will be a Python process, you could do this before the call:

os.environ["PYTHONUNBUFFERED"] = "1"

Or alternatively pass this in the env argument to Popen.

Otherwise, if you are on Linux/Unix, you can use the stdbuf tool. E.g. like:

cmd = ["stdbuf", "-oL"] + cmd

See also here about stdbuf or other options.

(See also here for the same answer.)

You can redirect print with the >> operator.

f = open(filename,'w')
print >>f, 'whatever'     # Python 2.x
print('whatever', file=f) # Python 3.x

In most cases, you're better off just writing to the file normally.

f.write('whatever')

or, if you have several items you want to write with spaces between, like print:

f.write(' '.join(('whatever', str(var2), 'etc')))

Try this from your shell:

$ od -A n -t d -N 1 /dev/urandom

Here, -t d specifies that the output format should be signed decimal; -N 1 says to read one byte from /dev/urandom.

To find a div of a certain class that contains a span at any depth containing certain text, try:

//div[contains(@class, 'measure-tab') and contains(.//span, 'someText')]

That said, this solution looks extremely fragile. If the table happens to contain a span with the text you're looking for, the div containing the table will be matched, too. I'd suggest to find a more robust way of filtering the elements. For example by using IDs or top-level document structure.

The approach you should take is to install pip for Python 3.2.

You do this in the following way:

$ curl -O https://bootstrap.pypa.io/get-pip.py
$ sudo python3.2 get-pip.py

Then, you can install things for Python 3.2 with pip-3.2, and install things for Python 2-7 with pip-2.7. The pip command will end up pointing to one of these, but I'm not sure which, so you will have to check.

Don't use print ..., if you don't want spaces. Use string concatenation or formatting.

Concatenation:

print 'Value is "' + str(value) + '"'

Formatting:

print 'Value is "{}"'.format(value)

The latter is far more flexible, see the str.format() method documentation and the Formatting String Syntax section.

You'll also come across the older % formatting style:

print 'Value is "%d"' % value
print 'Value is "%d", but math.pi is %.2f' % (value, math.pi)

but this isn't as flexible as the newer str.format() method.

I'll Explain how to add an image using Android studio(2.3.3). First you need to add the image into res/drawable folder in the project. Like below

Now in go to activity_main.xml (or any activity you need to add image) and select the Design view. There you can see your Palette tool box on left side. You need to drag and drop ImageView.

It will prompt you Resources dialog box. In there select Drawable under the project section you can see your image. Like below

Select the image you want press Ok you can see the image on the Design view. If you want it configure using xml it would look like below.

<ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/homepage"
        tools:layout_editor_absoluteX="55dp"
        tools:layout_editor_absoluteY="130dp" />

You need to give image location using

app:srcCompat="@drawable/imagename"

Short example:

if (typeof(arr[key]) === "undefined") {
  arr.push(key);
}

In NumPy it is quite simple

import numpy as np
P=2.45
S=[22, 33, 45.6, 21.6, 51.8]
SP = P*np.array(S)

I recommend taking a look at the NumPy tutorial for an explanation of the full capabilities of NumPy's arrays:

I know the topic is quite old, but such tools are always handy. I've used the resources above and created a version of NtpClient which allows asynchronously to acquire accurate time, instead of event based.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. I've read it will be fixed in the next release of Java, but it's not out yet. Supposedly, it was fixed in 1.7.0_60b01, but I can't find where to download it and 1.7.0_60b02 re-introduces the bug.

I managed to get around the problem by reverting back to JDK 1.7.0_25. Probably not the solution you wanted, but it's the only way I've been able to get it working. Don't forget add JDK 1.7.0_25 in Eclipse after installing the JDK.

Please DO NOT REPLY directly to this email but go to StackOverflow: Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined

I included the jquery.redirect.min.js plugin in the head section together with this json solution to submit with data

<script type="text/javascript">     
    $(function () {
     $('form').on('submit', function(e) {
       $.ajax({
        type: 'post',
        url: 'your_POST_URL',
        data: $('form').serialize(),
        success: function () {
         // now redirect
         $().redirect('your_POST_URL', {
          'input1': $("value1").val(), 
          'input2': $("value2").val(),
      'input3': $("value3").val()
       });
      }
   });
   e.preventDefault();
 });
 });
 </script>

Then immediately after the form I added

 $(function(){
     $( '#your_form_Id' ).submit();
    });

Thanks for this thread -- it helped me a lot too.

I learned something about .join() today.

These threads run in parallel:

d.start()
t.start()
d.join()
t.join()

and these run sequentially (not what I wanted):

d.start()
d.join()
t.start()
t.join()

In particular, I was trying to clever and tidy:

class Kiki(threading.Thread):
    def __init__(self, time):
        super(Kiki, self).__init__()
        self.time = time
        self.start()
        self.join()

This works! But it runs sequentially. I can put the self.start() in __ init __, but not the self.join(). That has to be done after every thread has been started.

join() is what causes the main thread to wait for your thread to finish. Otherwise, your thread runs all by itself.

So one way to think of join() as a "hold" on the main thread -- it sort of de-threads your thread and executes sequentially in the main thread, before the main thread can continue. It assures that your thread is complete before the main thread moves forward. Note that this means it's ok if your thread is already finished before you call the join() -- the main thread is simply released immediately when join() is called.

In fact, it just now occurs to me that the main thread waits at d.join() until thread d finishes before it moves on to t.join().

In fact, to be very clear, consider this code:

import threading
import time

class Kiki(threading.Thread):
    def __init__(self, time):
        super(Kiki, self).__init__()
        self.time = time
        self.start()

    def run(self):
        print self.time, " seconds start!"
        for i in range(0,self.time):
            time.sleep(1)
            print "1 sec of ", self.time
        print self.time, " seconds finished!"


t1 = Kiki(3)
t2 = Kiki(2)
t3 = Kiki(1)
t1.join()
print "t1.join() finished"
t2.join()
print "t2.join() finished"
t3.join()
print "t3.join() finished"

It produces this output (note how the print statements are threaded into each other.)

$ python test_thread.py
32   seconds start! seconds start!1

 seconds start!
1 sec of  1
 1 sec of 1  seconds finished!
 21 sec of
3
1 sec of  3
1 sec of  2
2  seconds finished!
1 sec of  3
3  seconds finished!
t1.join() finished
t2.join() finished
t3.join() finished
$ 

The t1.join() is holding up the main thread. All three threads complete before the t1.join() finishes and the main thread moves on to execute the print then t2.join() then print then t3.join() then print.

Corrections welcome. I'm also new to threading.

(Note: in case you're interested, I'm writing code for a DrinkBot, and I need threading to run the ingredient pumps concurrently rather than sequentially -- less time to wait for each drink.)

I'm using a old version of Hibernate (3.3.0) with a newest version of OpenEJB (4.6.0). My solution was:

EntityManagerImpl entityManager = (EntityManagerImpl)em.getDelegate();
Session session = entityManager.getSession();
Connection connection = session.connection();
Statement statement = null;
try {
    statement = connection.createStatement();
    statement.execute(sql);
    connection.commit();
} catch (SQLException e) {
    throw new RuntimeException(e);
}

I had an error after that:

Commit can not be set while enrolled in a transaction

Because this code above was inside a EJB Controller (you can't commit inside a transaction). I annotated the method with @TransactionAttribute(value = TransactionAttributeType.NOT_SUPPORTED) and the problem was gone.

Easy rule. Start with declaring everything private. And then progress towards the public as the needs arise and design warrants it.

When exposing members ask yourself if you are exposing representation choices or abstraction choices. The first is something you want to avoid as it will introduce too many dependencies on the actual representation rather than on its observable behavior.

As a general rule I try to avoid overriding method implementations by subclassing; it's too easy to screw up the logic. Declare abstract protected methods if you intend for it to be overridden.

Also, use the @Override annotation when overriding to keep things from breaking when you refactor.

Under OSX, to avoid this issue and avoid other problems with developing on a case-insensitive filesystem, you can use Disk Utility to create a case sensitive virtual drive / disk image.

Run disk utility, create new disk image, and use the following settings (or change as you like, but keep it case sensitive):

Make sure to tell git it is now on a case sensitive FS:

git config core.ignorecase false

To trigger an enter keypress, I had to modify @ebynum response, specifically, using the keyCode property.

e = $.Event('keyup');
e.keyCode= 13; // enter
$('input').trigger(e);

If you want change bottom line without using app colors, use these lines in your theme:

<item name="android:editTextStyle">@android:style/Widget.EditText</item>
<item name="editTextStyle">@android:style/Widget.EditText</item>

I don't know another solution.

In your JSP at line <form> tag, try this code

<form name="registrationform" action="Register" method="post">

This may be too simplistic of an answer (I am still new here), but what I have done in the past to remedy this situation is figured out the percentage of the screen I would like the image to take up. For example, there is one webpage I am working on where the logo must take up 30% of the screen size to look best. I played around and finally tried this code and it has worked for me thus far:

img {
width:30%;
height:auto;
}

That being said, this will change all of your images to be 30% of the screen size at all times. To get around this issue, simply make this a class and apply it to the image that you desire to be at 30% directly. Here is an example of the code I wrote to accomplish this on the aforementioned site:

the CSS portion:

.logo {

Alternatively, you could place ever image you hope to automatically resize into a div of its own and use the class tag option on each div (creating now class tags whenever needed), but I feel like that would cause a lot of extra work eventually. But, if the site calls for it: the site calls for it.

Hopefully this helps. Have a great day!

If you mean when you are not the person writing the web page, then you could disable the add ons you do not wish to use with the Manage Add-Ons IE Options screen added in Win XP SP2

I've found that this is a sign that the server where you're deploying code has an old .NET framework installed that doesn't support TLS 1.1 or TLS 1.2. Steps to fix:

1. Installing the latest .NET Runtime on your production servers (IIS & SQL)
2. Installing the latest .NET Developer Pack on your development machines.
3. Change the "Target framework" settings in your Visual Studio projects to the latest .NET framework.

You can get the latest .NET Developer Pack and Runtime from this URL: http://getdotnet.azurewebsites.net/target-dotnet-platforms.html

As said, JsonMappingException: out of START_ARRAY token exception is thrown by Jackson object mapper as it's expecting an Object {} whereas it found an Array [{}] in response.

A simpler solution could be replacing the method getLocations with:

public static List<Location> getLocations(InputStream inputStream) {
    ObjectMapper objectMapper = new ObjectMapper();
    try {
        TypeReference<List<Location>> typeReference = new TypeReference<>() {};
        return objectMapper.readValue(inputStream, typeReference);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

On the other hand, if you don't have a pojo like Location, you could use:

TypeReference<List<Map<String, Object>>> typeReference = new TypeReference<>() {};
return objectMapper.readValue(inputStream, typeReference);

Faced with the same problem, I was able to solve it using only vanilla JS, but in an ugly way. To be more accurate, in a non-procedural way. I removed all my function parameters and return values and replaced them with global variables, and now the functions only serve as containers for lines of code - they're no longer logical units.

In my case, I also had the added complication of needing many confirmations (as a parser works through a text). My solution was to put everything up to the first confirmation in a JS function that ends by painting my custom popup on the screen, and then terminating.

Then the buttons in my popup call another function that uses the answer and then continues working (parsing) as usual up to the next confirmation, when it again paints the screen and then terminates. This second function is called as often as needed.

Both functions also recognize when the work is done - they do a little cleanup and then finish for good. The result is that I have complete control of the popups; the price I paid is in elegance.

do wget -r -l0 www.oldsite.com

Then just find www.oldsite.com would reveal all urls, I believe.

Alternatively, just serve that custom not-found page on every 404 request! I.e. if someone used the wrong link, he would get the page telling that page wasn't found, and making some hints about site's content.

There is no guaranteed solution to this problem because the phone number is not physically stored on all SIM-cards, or broadcasted from the network to the phone. This is especially true in some countries which requires physical address verification, with number assignment only happening afterwards. Phone number assignment happens on the network - and can be changed without changing the SIM card or device (e.g. this is how porting is supported).

I know it is pain, but most likely the best solution is just to ask the user to enter his/her phone number once and store it.

The accepted answer shows too complicated way. As Forresto claims in his answer, "it does seem to add them in the DOM explorer, but not on the screen" and the reason for this is different namespaces for html and svg.

The easiest workaround is to "refresh" whole svg. After appending circle (or other elements), use this:

$("body").html($("body").html());

This does the trick. The circle is on the screen.

Or if you want, use a container div:

$("#cont").html($("#cont").html());

And wrap your svg inside container div:

<div id="cont">
    <svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 100" width="200px" height="100px">
    </svg>
</div>

The functional example:
http://jsbin.com/ejifab/1/edit

The advantages of this technique:

• you can edit existing svg (that is already in DOM), eg. created using Raphael or like in your example "hard coded" without scripting.
• you can add complex element structures as strings eg. $('svg').prepend('<defs><marker></marker><mask></mask></defs>'); like you do in jQuery.
• after the elements are appended and made visible on the screen using $("#cont").html($("#cont").html()); their attributes can be edited using jQuery.

EDIT:

The above technique works with "hard coded" or DOM manipulated ( = document.createElementNS etc.) SVG only. If Raphael is used for creating elements, (according to my tests) the linking between Raphael objects and SVG DOM is broken if $("#cont").html($("#cont").html()); is used. The workaround to this is not to use $("#cont").html($("#cont").html()); at all and instead of it use dummy SVG document.

This dummy SVG is first a textual representation of SVG document and contains only elements that are needed. If we want eg. to add a filter element to Raphael document, the dummy could be something like <svg id="dummy" style="display:none"><defs><filter><!-- Filter definitons --></filter></defs></svg>. The textual representation is first converted to DOM using jQuery's $("body").append() method. And when the (filter) element is in DOM, it can be queried using standard jQuery methods and appended to the main SVG document which is created by Raphael.

Why this dummy is needed? Why not to add a filter element strictly to Raphael created document? If you try it using eg. $("svg").append("<circle ... />"), it is created as html element and nothing is on screen as described in answers. But if the whole SVG document is appended, then the browser handles automatically the namespace conversion of all the elements in SVG document.

An example enlighten the technique:

// Add Raphael SVG document to container element
var p = Raphael("cont", 200, 200);
// Add id for easy access
$(p.canvas).attr("id","p");
// Textual representation of element(s) to be added
var f = '<filter id="myfilter"><!-- filter definitions --></filter>';

// Create dummy svg with filter definition 
$("body").append('<svg id="dummy" style="display:none"><defs>' + f + '</defs></svg>');
// Append filter definition to Raphael created svg
$("#p defs").append($("#dummy filter"));
// Remove dummy
$("#dummy").remove();

// Now we can create Raphael objects and add filters to them:
var r = p.rect(10,10,100,100);
$(r.node).attr("filter","url(#myfilter)");

Full working demo of this technique is here: http://jsbin.com/ilinan/1/edit.

( I have (yet) no idea, why $("#cont").html($("#cont").html()); doesn't work when using Raphael. It would be very short hack. )

You dont need call addSheet() method. After creating sheet, it already add to excel. Here i fixed some codes:

    //First sheet
    $sheet = $objPHPExcel->getActiveSheet();

    //Start adding next sheets
    $i=0;
    while ($i < 10) {

      // Add new sheet
      $objWorkSheet = $objPHPExcel->createSheet($i); //Setting index when creating

      //Write cells
      $objWorkSheet->setCellValue('A1', 'Hello'.$i)
                   ->setCellValue('B2', 'world!')
                   ->setCellValue('C1', 'Hello')
                   ->setCellValue('D2', 'world!');

      // Rename sheet
      $objWorkSheet->setTitle("$i");

      $i++;
    }

pause command is what you looking for. If you looking ONLY the case when enter is hit you can abuse the runas command:

runas /user:# "" >nul 2>&1

the screen will be frozen until enter is hit.What I like more than set/p= is that if you press other buttons than enter they will be not displayed.

When elements are positioned outside the normal flow, they can overlap other elements.

according to Overlapping Elements section on http://web.archive.org/web/20130501103219/http://w3schools.com/css/css_positioning.asp

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

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

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

The solution is very simple and worked for me.

Try this :

git pull --rebase <url>

then

git push -u origin master

AsyncTask have four methods..

onPreExecute  -- for doing something before calling background task in Async

doInBackground  -- operation/Task to do in Background

onProgressUpdate  -- it is for progress Update

onPostExecute  -- this method calls after asyncTask return from doInBackground.

you can call your work on onPostExecute() it calls after returning from doInBackground()

onPostExecute is what you need to Implement.

If you scale 1600x900 to 1280x720 you have

scale_x = 1280.0/1600
scale_y = 720.0/900

Then you can use it to find button size, and button position

button_width  = 300 * scale_x
button_height = 300 * scale_y

button_x = 1440 * scale_x
button_y = 860  * scale_y

If you scale 1280x720 to 1600x900 you have

scale_x = 1600.0/1280
scale_y = 900.0/720

and rest is the same.

I add .0 to value to make float - otherwise scale_x, scale_y will be rounded to integer - in this example to 0 (zero) (Python 2.x)

Your question is not clear: you want to give "checkbox array id" at input and get true/false at output - in this way you will not know which checkbox was checked (as your function name suggest). So below there is my proposition of body of your isCheckedById which on input take checkbox id and on output return true/false (it's very simple but your ID should not be keyword),

this[id].checked

function isCheckedById(id) {
  return this[id].checked;
}



// TEST

function check() {
  console.clear()
  console.log('1',isCheckedById("myCheckbox1"));
  console.log('2',isCheckedById("myCheckbox2"));
  console.log('3',isCheckedById("myCheckbox3"));
}

<label><input id="myCheckbox1" type="checkbox">check 1</label>
<label><input id="myCheckbox2" type="checkbox">check 2</label>
<label><input id="myCheckbox3" type="checkbox">check 3</label>
<!-- label around inputs makes text clickable -->
<br>
<button onclick="check()">show checked</button>

In case you are into functional this is a function written in Scala showing how you could copy an input stream to an output stream using only vals (and not vars).

def copyInputToOutputFunctional(inputStream: InputStream, outputStream: OutputStream,bufferSize: Int) {
  val buffer = new Array[Byte](bufferSize);
  def recurse() {
    val len = inputStream.read(buffer);
    if (len > 0) {
      outputStream.write(buffer.take(len));
      recurse();
    }
  }
  recurse();
}

Note that this is not recommended to use in a java application with little memory available because with a recursive function you could easily get a stack overflow exception error

Exactly what you need:) You can choose callback version or Promise version. Note that promises will work in IE only with Promise polyfill lib.You can put this code once on a page, and this function will appear in all your files.

The loadend event is fired when progress has stopped on the loading of a resource (e.g. after "error", "abort", or "load" have been dispatched)

Callback version

        File.prototype.convertToBase64 = function(callback){
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    callback(e.target.result, e.target.error);
                };   
                reader.readAsDataURL(this);
        };

        $("#asd").on('change',function(){
          var selectedFile = this.files[0];
          selectedFile.convertToBase64(function(base64){
               alert(base64);
          }) 
        });

Promise version

    File.prototype.convertToBase64 = function(){
         return new Promise(function(resolve, reject) {
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    resolve({
                      fileName: this.name,
                      result: e.target.result, 
                      error: e.target.error
                    });
                };   
                reader.readAsDataURL(this);
        }.bind(this)); 
    };

    FileList.prototype.convertAllToBase64 = function(regexp){
      // empty regexp if not set
      regexp = regexp || /.*/;
      //making array from FileList
      var filesArray = Array.prototype.slice.call(this);
      var base64PromisesArray = filesArray.
           filter(function(file){
             return (regexp).test(file.name)
           }).map(function(file){
             return file.convertToBase64();
           });
      return Promise.all(base64PromisesArray);
    };

    $("#asd").on('change',function(){
      //for one file
      var selectedFile = this.files[0];
      selectedFile.convertToBase64().
          then(function(obj){
            alert(obj.result);
          });
      });
      //for all files that have file extention png, jpeg, jpg, gif
      this.files.convertAllToBase64(/\.(png|jpeg|jpg|gif)$/i).then(function(objArray){
            objArray.forEach(function(obj, i){
                  console.log("result[" + obj.fileName + "][" + i + "] = " + obj.result);
            });
      });
    })

<input type="file" id="asd" multiple/>

One best way is by using window.INITIAL_STATE

<script src="/firstfile.js">
    // first.js
    window.__INITIAL_STATE__ = {
      back  : "#fff",
      front : "#888",
      side  : "#369"
    };
</script>
<script src="/secondfile.js">
    //second.js
    console.log(window.__INITIAL_STATE__)
    alert (window.__INITIAL_STATE__);
</script>

If you do it a lot I would suggest writing a function that compares the two structures. That way, if you ever change the structure you only need to change the compare in one place.

As for how to do it.... You need to compare every element individually

You could try:

print ''.join(ch for ch in some_string if ch.isalnum())

To include all files and directories:

archive.bulk([
  {
    expand: true,
    cwd: "temp/freewheel-bvi-120",
    src: ["**/*"],
    dot: true
  }
]);

It uses node-glob(https://github.com/isaacs/node-glob) underneath, so any matching expression compatible with that will work.

How about a bookmarklet? It would show them how to manipulate something that they use every day (the Internet) without requiring any development tools.

Changing

RestResponse response = client.Execute(request);

to

IRestResponse response = client.Execute(request);

worked for me.

I want to import existing maven project into eclipse. I found 2 ways to do it, one is through running from command line mvn eclipse:eclipse and another is to install maven eclipse plugin from eclipse. What is the difference between the both and which one is preferable?

The maven-eclipse-plugin is a Maven plugin and has always been there (one of the first plugin available with Maven 1, one of the first plugin migrated to Maven 2). It has been during a long time the only decent way to integrateimport an existing maven project with Eclipse. Actually, it doesn't provide real integration, it just generates the .project and .classpath files (it has also WTP support) from a Maven project. I've used this plugin during years and was very happy with it (and very unsatisfied at this time by Eclipse plugins for Maven like m2eclipse).

The m2eclipse plugin is one of the Eclipse plugins for Maven. It's actually the first and most mature of the projects aimed at integrating Maven within the Eclipse IDE (this has not always been the case, it was not really usable ~2 years ago, see the feedback in Mevenide vs. M2Eclipse, Q for Eclipse/IAM). But, even if I do not use things like creating a Maven project from Eclipse or the POM editor or other fancy wizards, I have to say that this plugin is now totally usable, provides very smooth integration, has nice features... In other words, I finally switched to it :) I'd now recommend it to any user (advanced or beginners).

If I install maven eclipse plugin through the eclipse menu Help -> Install New Software, do I still need to modify my pom.xml to include the maven eclipse plugin in the plugins section?

This question is a bit confusing but the answer is no. With the m2eclipse plugin installed, just right-click the package explorer and Import... > Maven projects to import an existing maven project into Eclipse.

It is simple actually, like C programming you just need to pass the array indices on the right hand side while declaration. But yeah the syntax will be like [0:3] for 4 elements.

reg a[0:3]; 

This will create a 1D of array of single bit. Similarly 2D array can be created like this:

reg [0:3][0:2];

Now in C suppose you create a 2D array of int, then it will internally create a 2D array of 32 bits. But unfortunately Verilog is an HDL, so it thinks in bits rather then bunch of bits (though int datatype is there in Verilog), it can allow you to create any number of bits to be stored inside an element of array (which is not the case with C, you can't store 5-bits in every element of 2D array in C). So to create a 2D array, in which every individual element can hold 5 bit value, you should write this:

reg [0:4] a [0:3][0:2];

Running eclipse in Administrator Mode fixed it for me. You can do this by [Right Click] -> Run as Administrator on the eclipse.exe from your install dir.

I was on a working environment with win7 machine having restrictive permission. I also did remove the .lock and .log files but that did not help. It can be a combination of all as well that made it work.

This should work:

if (!string.IsNullOrWhiteSpace(dateTimeEnd))
    eventCustom.DateTimeEnd = DateTime.Parse(dateTimeEnd);
else
    eventCustom.DateTimeEnd = null;

Note that this will throw an exception if the string is not in the correct format.

Quick-to-write alterantive

Even though is not the fastest choice, if performance is not an issue you can use:

sum(~np.isnan(data)).

Performance:

In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop

In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop

In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop

Here is a simple and more update format of getting the data:

   $now = new \DateTime('now');
   $month = $now->format('m');
   $year = $now->format('Y');

The motivation is to write code that doesn't depend explicitly on Spring. That way, if you choose to switch containers, you don't have to rewrite any code.

Think of the container as something is invisible to your code, magically providing for its needs, without being asked.

Dependency injection is a counterpoint to the "service locator" pattern. If you are going to lookup dependencies by name, you might as well get rid of the DI container and use something like JNDI.

In bash foo is the name of the variable, and $ is an operator which means 'get the value of'.

In perl $foo is the name of the variable.

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

\d matches any single digit in most regex grammar styles, including python. Regex Reference

204 No Content

The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

According to the RFC part for the status code 204, it seems to me a valid choice for a GET request.

A 404 Not Found, 200 OK with empty body and 204 No Content have completely different meaning, sometimes we can't use proper status code but bend the rules and they will come back to bite you one day or later. So, if you can use proper status code, use it!

I think the choice of GET or POST is very personal as both of them will do the work but I would recommend you to keep a POST instead of a GET, for two reasons:

• You want the other part (the servlet if I understand correctly) to perform an action not retrieve some data from it.
• By default GET requests are cacheable if there are no parameters present in the URL, a POST is not.

also this syntax for ternary operator will work:

  ng-style="<$scope.var><condition> ? {
        '<css-prop-1>':((<value>) / (<value2>)*100)+'%',
        '<css-prop-2>':'<string>'
      } : {
        '<css-prop-1>':'<string>',
        '<css-prop-2>':'<string>'
      }"

where <value> are $scope property values. In example:

ng-style="column.histograms.value=>0 ? 
  {
    'width':((column.histograms.value) / (column.histograms.limit)*100)+'%',
    'background':'#F03040'
  } : {
    'width':'1px',
    'background':'#2E92FA'
  }"

```

this allows for some calculaton into the css property values.

int(limit) returns the value converted into an integer, and doesn't change it in place as you call the function (which is what you are expecting it to).

Do this instead:

limit = int(limit)

Or when definiting limit:

if 'limit' in user_data :
    limit = int(user_data['limit'])

What include does is copying all the contents from the file (which is the argument inside the <> or the "" ), so when the preproccesor finishes its work main.cpp will look like:

// iostream stuff

int foo(int a){
    return ++a;
}

int main(int argc, char *argv[])
{
   int x=42;
   std::cout << x <<std::endl;
   std::cout << foo(x) << std::endl;
   return 0;
}

So foo will be defined in main.cpp, but a definition also exists in foop.cpp, so the compiler "gets confused" because of the function duplication.

Hello you can make use of input and output. Input let you to pass variable form parent to child. Output the same but from child to parent.

The easiest way is to pass "startdate" and "endDate" as input

<calendar [startDateInCalendar]="startDateInSearch" [endDateInCalendar]="endDateInSearch" ></calendar>

In this way you have your startdate and enddate directly in search page. Let me know if it works, or think another way. Thanks

In the context of Drupal, the difference will depend whether clean URLs are on or not.

With them off, $_SERVER['REQUEST_URI'] will have the full path of the page as called w/ /index.php, while $_GET["q"] will just have what is assigned to q.

With them on, they will be nearly identical w/o other arguments, but $_GET["q"] will be missing the leading /. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.

Just need:

string stringName = EnumDisplayStatus.Visible.ToString("f");
// stringName == "Visible"

I have created a JSFiddle where I have two nested ng-repeats with tables, and the parent ng-repeat on tbody. If you inspect any row in the table, you will see there are six tbody elements, i.e. the parent level.

( Side note: This fills up the DOM if you have a lot of data on both levels, so I am therefore working on a directive to fetch data and replace, i.e. adding into DOM when clicking parent and removing when another is clicked or same parent again. To get the kind of behavior you find on Prisjakt.nu, if you scroll down to the computers listed and click on the row (not the links). If you do that and inspect elements you will see that a tr is added and then removed if parent is clicked again or another. )

Not possible without iterating to build a new list. You can wrap the list in a container that implements IList.

You can use LINQ to get a lazy evaluated version of IEnumerable<string> from an object list like this:

var stringList = myList.OfType<string>();

You can also try

    interface IData{
        id: number;
        name:string;
    }

    let userTestStatus:Record<string,IData> = {
        "0": { "id": 0, "name": "Available" },
        "1": { "id": 1, "name": "Ready" },
        "2": { "id": 2, "name": "Started" }
    };

To check how record works: https://www.typescriptlang.org/docs/handbook/utility-types.html#recordkt

Here in our case Record is used to declare an object whose key will be a string and whose value will be of type IData so now it will provide us intellisense when we will try to access its property and will throw type error in case we will try something like userTestStatus[0].nameee

if you want to choose dynamically the path to the log file use the method written in this link: method to dynamic choose the log file path.

if you want you can set the path to where your app EXE file exists like this -

var logFileLocation = System.IO.Path.GetDirectoryName
(System.Reflection.Assembly.GetEntryAssembly().Location);

and then send this 'logFileLocation' to the method written in the link above like this:

Initialize(logFileLocation);

and you are ready to go! :)

Here is an example of reading and writing a list of objects of type SNStock that implements NSCoding - we have an accessor for the entire list, watchlist, and two methods to add and remove objects, that is addStock(stock: SNStock) and removeStock(stock: SNStock).

import Foundation

class DWWatchlistController {

  private let kNSUserDefaultsWatchlistKey: String = "dw_watchlist_key"

  private let userDefaults: NSUserDefaults

  private(set) var watchlist:[SNStock] {

    get {
      if let watchlistData : AnyObject = userDefaults.objectForKey(kNSUserDefaultsWatchlistKey) {
        if let watchlist : AnyObject = NSKeyedUnarchiver.unarchiveObjectWithData(watchlistData as! NSData) {
          return watchlist as! [SNStock]
        }
      }
      return []
    }

    set(watchlist) {
      let watchlistData = NSKeyedArchiver.archivedDataWithRootObject(watchlist)
      userDefaults.setObject(watchlistData, forKey: kNSUserDefaultsWatchlistKey)
      userDefaults.synchronize()
    }
  }

  init() {
    userDefaults = NSUserDefaults.standardUserDefaults()
  }

  func addStock(stock: SNStock) {
    var watchlist = self.watchlist
    watchlist.append(stock)
    self.watchlist = watchlist
  }

  func removeStock(stock: SNStock) {
    var watchlist = self.watchlist
    if let index = find(watchlist, stock) {
      watchlist.removeAtIndex(index)
      self.watchlist = watchlist
    }
  }

}

Remember that your object needs to implement NSCoding or else the encoding won't work. Here is what SNStock looks like:

import Foundation

class SNStock: NSObject, NSCoding
{
  let ticker: NSString
  let name: NSString

  init(ticker: NSString, name: NSString)
  {
    self.ticker = ticker
    self.name = name
  }

  //MARK: NSCoding

  required init(coder aDecoder: NSCoder) {
    self.ticker = aDecoder.decodeObjectForKey("ticker") as! NSString
    self.name = aDecoder.decodeObjectForKey("name") as! NSString
  }

  func encodeWithCoder(aCoder: NSCoder) {
    aCoder.encodeObject(ticker, forKey: "ticker")
    aCoder.encodeObject(name, forKey: "name")
  }

  //MARK: NSObjectProtocol

  override func isEqual(object: AnyObject?) -> Bool {
    if let object = object as? SNStock {
      return self.ticker == object.ticker &&
        self.name == object.name
    } else {
      return false
    }
  }

  override var hash: Int {
    return ticker.hashValue
  }
}

Hope this helps!

import scala.io.Source

object Demo {

  def main(args: Array[String]): Unit = {

    val ipfileStream = getClass.getResourceAsStream("/folder/a-words.txt")
    val readlines = Source.fromInputStream(ipfileStream).getLines
    readlines.foreach(readlines => println(readlines))

  }

}

Use the timeit module. It's very easy. Run your example.py file so it is active in the Python Shell, you should now be able to call your function in the shell. Try it out to check it works

>>>fun(input)
output

Good, that works, now import timeit and set up a timer

>>>import timeit
>>>t = timeit.Timer('example.fun(input)','import example')
>>>

Now we have our timer set up we can see how long it takes

>>>t.timeit(number=1)
some number here

And there we go, it will tell you how many seconds (or less) it took to execute that function. If it's a simple function then you can increase it to t.timeit(number=1000) (or any number!) and then divide the answer by the number to get the average.

I hope this helps.

While cloning you might be using SSH in the dropdown list. Change it to Https and then clone.

The most common solution is to strip the integer portion of the number and compare it to zero like so:

function Test()
{
     var startVal = 123.456
     alert( (startVal - Math.floor(startVal)) != 0 )
}

Check this out using Set and ES6 filter.

  let result = arrayOfObjects.filter( el => (-1 == listToDelete.indexOf(el.id)) );
  console.log(result);

Here is JsFiddle: https://jsfiddle.net/jsq0a0p1/1/

when .slice() is called normally, this is an Array, and then it just iterates over that Array, and does its work.

 //ARGUMENTS
function func(){
  console.log(arguments);//[1, 2, 3, 4]

  //var arrArguments = arguments.slice();//Uncaught TypeError: undefined is not a function
  var arrArguments = [].slice.call(arguments);//cp array with explicity THIS  
  arrArguments.push('new');
  console.log(arrArguments)
}
func(1,2,3,4)//[1, 2, 3, 4, "new"]

Hear it from the Horse's Mouth : APUE (Richard Stevens).
To the kernel, all open files are referred to by File Descriptors. A file descriptor is a non-negative number.

When we open an existing file or create a new file, the kernel returns a file descriptor to the process. The kernel maintains a table of all open file descriptors, which are in use. The allotment of file descriptors is generally sequential and they are allotted to the file as the next free file descriptor from the pool of free file descriptors. When we closes the file, the file descriptor gets freed and is available for further allotment.
See this image for more details :

When we want to read or write a file, we identify the file with the file descriptor that was returned by open() or create() function call, and use it as an argument to either read() or write().
It is by convention that, UNIX System shells associates the file descriptor 0 with Standard Input of a process, file descriptor 1 with Standard Output, and file descriptor 2 with Standard Error.
File descriptor ranges from 0 to OPEN_MAX. File descriptor max value can be obtained with ulimit -n. For more information, go through 3rd chapter of APUE Book.

An object becomes eligible for Garbage collection or GC if it's not reachable from any live threads or by any static references.

In other words, you can say that an object becomes eligible for garbage collection if its all references are null. Cyclic dependencies are not counted as the reference so if object A has a reference to object B and object B has a reference to Object A and they don't have any other live reference then both Objects A and B will be eligible for Garbage collection.

Heap Generations for Garbage Collection -

Java objects are created in Heap and Heap is divided into three parts or generations for the sake of garbage collection in Java, these are called as Young(New) generation, Tenured(Old) Generation and Perm Area of the heap.

New Generation is further divided into three parts known as Eden space, Survivor 1 and Survivor 2 space. When an object first created in heap its gets created in new generation inside Eden space and after subsequent minor garbage collection if an object survives its gets moved to survivor 1 and then survivor 2 before major garbage collection moved that object to old or tenured generation.

Perm space of Java Heap is where JVM stores Metadata about classes and methods, String pool and Class level details.

Refer here for more : Garbage Collection

You can't force JVM to run Garbage Collection though you can make a request using System.gc() or Runtime.gc() method.

In java.lang.System

public static void gc() {
    Runtime.getRuntime().gc();  
}

In java.lang.Runtime

public native void gc();  // note native  method

Mark and Sweep Algorithm -

This is one of the most popular algorithms used by Garbage collection. Any garbage collection algorithm must perform 2 basic operations. One, it should be able to detect all the unreachable objects and secondly, it must reclaim the heap space used by the garbage objects and make the space available again to the program.

The above operations are performed by Mark and Sweep Algorithm in two phases:

1. Mark phase
2. Sweep phase

How do I change Android Studio editor's background color?

Changing Editor's Background

Open Preference > Editor (In IDE Settings Section) > Colors & Fonts > Darcula or Any item available there

IDE will display a dialog like this, Press 'No'

Darcula color scheme has been set for editors. Would you like to set Darcula as default Look and Feel?

Changing IDE's Theme

Open Preference > Appearance (In IDE Settings Section) > Theme > Darcula or Any item available there

Press OK. Android Studio will ask you to restart the IDE.

Try the code below and.....

1 - change the name of the MENU as in my sample the menuitem was called 'Form7ToolStripMenuItem_Click'

2 - make SURE to paste it into an MDIFORM and not just a basic FORM

Then let me know if the CHILD form still shows OUTSIDE the parent form

Private Sub Form7ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form7ToolStripMenuItem.Click

    Dim NewForm As System.Windows.Forms.Form
    NewForm = New System.Windows.Forms.Form
    'USE THE NEXT LINE - to add an existing CUSTOM form you already have
    'NewForm = Form7                         
    NewForm.Width = 400
    NewForm.Height = 250
    NewForm.MdiParent = Me
    NewForm.Text = "CAPTION"
    NewForm.Show()
    DockChildForm(NewForm, "left")          'dock left
    'DockChildForm(NewForm, "right")         'dock right
    'DockChildForm(NewForm, "top")           'dock top
    'DockChildForm(NewForm, "bottom")        'doc bottom
    'DockChildForm(NewForm, "full")          'fill the client area (maximise the child INSIDE the parent)
    'DockChildForm(NewForm, "Anything-Else") 'center the form

End Sub

Private Sub DockChildForm(ByRef Form2Dock As Form, ByVal Position As String)

    Dim XYpoint As Point
    Select Case Position
        Case "left"
            Form2Dock.Dock = DockStyle.Left
        Case "top"
            Form2Dock.Dock = DockStyle.Top
        Case "right"
            Form2Dock.Dock = DockStyle.Right
        Case "bottom"
            Form2Dock.Dock = DockStyle.Bottom
        Case "full"
            Form2Dock.Dock = DockStyle.Fill
        Case Else
            XYpoint = New Point
            XYpoint.X = ((Me.ClientSize.Width - Form2Dock.Width) / 2)
            XYpoint.Y = ((Me.ClientSize.Height - Form2Dock.Height) / 2)
            Form2Dock.Location = XYpoint
    End Select
End Sub

Possible solution with string_view

void do_it_with_string_view( void )
{
    std::string a { "12345" };
    for ( std::string_view v { a }; v.size() - 1; v.remove_prefix( 1 ) )
        std::cout << v.substr( 0, 2 ) << " ";
    std::cout << std::endl;
}

Simple solution with an example :

<div id="id_div">
  <p>content<p>
</div>

Move this DIV to other DIV with id = "other_div_id"

$('#other_div_id').prepend( $('#id_div') );

Finish

First off, it might not be good to just go by recall alone. You can simply achieve a recall of 100% by classifying everything as the positive class. I usually suggest using AUC for selecting parameters, and then finding a threshold for the operating point (say a given precision level) that you are interested in.

For how class_weight works: It penalizes mistakes in samples of class[i] with class_weight[i] instead of 1. So higher class-weight means you want to put more emphasis on a class. From what you say it seems class 0 is 19 times more frequent than class 1. So you should increase the class_weight of class 1 relative to class 0, say {0:.1, 1:.9}. If the class_weight doesn't sum to 1, it will basically change the regularization parameter.

For how class_weight="auto" works, you can have a look at this discussion. In the dev version you can use class_weight="balanced", which is easier to understand: it basically means replicating the smaller class until you have as many samples as in the larger one, but in an implicit way.

if you want to set jvm args on eclipse you can use below:

see below two links to accomplish it:

1. eclipse setting to pass jvm args to java
2. eclipse setting to pass jvm args to java and adding to run config on eclipse
   

And for Tomcat you can create a setenv.bat file in bin folder of Tomcat and add below lines to it :

echo "hello im starting setenv"
set CATALINA_OPTS=-DNLP.home=${NLP.home} -Dhostname=${hostname}

Go to /etc/apache2/apache2.conf

You have to edit that file (you should have root permission). Change directory text as bellow:

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted

Now you have to restart apache.

service apache2 restart

If you have a month wise get the last date of the month then,

public function getLastDateOfMonth($month)
    {
        $date = date('Y').'-'.$month.'-01';  //make date of month 
        return date('t', strtotime($date)); 
    }

$this->getLastDateOfMonth(01); //31

I know this question has been asked years ago but still wanted to share how I usually compile multiple c++ files.

1. Let's say you have 5 cpp files, all you have to do is use the * instead of typing each cpp files name E.g g++ -c *.cpp -o myprogram.
2. This will generate "myprogram"
3. run the program ./myprogram

that's all!!

The reason I'm using * is that what if you have 30 cpp files would you type all of them? or just use the * sign and save time :)

p.s Use this method only if you don't care about makefile.

Tarkus's answer works well. However, I would suggest replacing VIEWSTATE with SESSION.

The current page's VIEWSTATE only works while the current page posts back to itself and is gone once the user is redirected away to another page. SESSION persists the sort order on more than just the current page's post-back. It persists it across the entire duration of the session. This means that the user can surf around to other pages, and when he comes back to the given page, the sort order he last used still remains. This is usually more convenient.

There are other methods, too, such as persisting user profiles.

I recommend this article for a very good explanation of ViewState and how it works with a web page's life cycle: https://msdn.microsoft.com/en-us/library/ms972976.aspx

To understand the difference between VIEWSTATE, SESSION and other ways of persisting variables, I recommend this article: https://msdn.microsoft.com/en-us/library/75x4ha6s.aspx

For changing the color

MS-SQL has a setting to prevent recursive trigger firing. This is confirgured via the sp_configure stored proceedure, where you can turn recursive or nested triggers on or off.

In this case, it would be possible, if you turn off recursive triggers to link the record from the inserted table via the primary key, and make changes to the record.

In the specific case in the question, it is not really a problem, because the result is to delete the record, which won't refire this particular trigger, but in general that could be a valid approach. We implemented optimistic concurrency this way.

The code for your trigger that could be used in this way would be:

ALTER TRIGGER myTrigger
    ON someTable
    AFTER INSERT
AS BEGIN
DELETE FROM someTable
    INNER JOIN inserted on inserted.primarykey = someTable.primarykey
    WHERE ISNUMERIC(inserted.someField) = 1
END

I know you ask how to disable the option, but I figure the end users visual outcome is the same with this solution, although it is probably marginally less resource demanding.

Use the optgroup tag, like so :

<select name="tagging">
    <optgroup label="Choose Tagging">
        <option value="Option A">Option A</option>
        <option value="Option B">Option B</option>
        <option value="Option C">Option C</option>
    </optgroup>
</select>

it doesn't, however, solve the problem, because on e.g. open SUSE Tumbleweed, custom source build is triggering the same 401 error on default web page, which is configured accordingly with Indexes and

Require all granted

From the GNU UPC website:

Compiler build fails with fatal error: gnu/stubs-32.h: No such file or directory

This error message shows up on the 64 bit systems where GCC/UPC multilib feature is enabled, and it indicates that 32 bit version of libc is not installed. There are two ways to correct this problem:

• Install 32 bit version of glibc (e.g. glibc-devel.i686 on Fedora, CentOS, ..)
• Disable 'multilib' build by supplying "--disable-multilib" switch on the compiler configuration command

Adding export PATH="$PATH:~/.composer/vendor/bin" to ~/.bashrc works in your case because you only need it when you run the terminal.
For the sake of completeness, appending it to PATH in /etc/environment (sudo gedit /etc/environment and adding ~/.composer/vendor/bin in PATH) will also work even if it is called by other programs because it is system-wide environment variable.

This can be due to system cannot find firefox installed location on path.

Try following code, which should work.

System.setProperty("webdriver.firefox.bin","C:\\Program Files\\Mozilla Firefox\\firefox.exe"); 
System.setProperty("webdriver.gecko.driver","<location of geckodriver>\\geckodriver.exe");

I had the same problem. Following worked for me

Go to the web application --> Properties --> Silverlight Applications

If you don't see you Silverlight application in the list there then click Add and select your Silverlight Application from "Project" dropdown and Add it.

Code offset dynamic for dynamic page

var pos=$('#send').offset().top;
$('#loading').offset({ top : pos-220});

You can unstage files from the index using

git reset HEAD -- path/to/file

Just like git add, you can unstage files recursively by directory and so forth, so to unstage everything at once, run this from the root directory of your repository:

git reset HEAD -- .

Also, for future reference, the output of git status will tell you the commands you need to run to move files from one state to another.

I got this error(classNotFoundException for main class), I actually changed pom version , so did maven install again and then error vanished.

This error can appear when the web server can't access the mail server. Make sure the web server can reach the mail server, for instance pinging it.

The claims that you have to mock it at the top of your file are false.

Mock a named ES Import:

// import the named module
import { useWalkthroughAnimations } from '../hooks/useWalkthroughAnimations';

// mock the file and its named export
jest.mock('../hooks/useWalkthroughAnimations', () => ({
  useWalkthroughAnimations: jest.fn()
}));

// do whatever you need to do with your mocked function
useWalkthroughAnimations.mockReturnValue({ pageStyles, goToNextPage, page });

        { "str.Concat", n => string.Concat(value) },
        { "string +", n => "" + value },
        { "Convert", n => Convert.ToString(value) },
    }.Vs();
}

void test(object value) {
    new Perf<string> {
        { "coallesce", n => (value ?? string.Empty).ToString() },
        { "nullcheck", n => value == null ? string.Empty : value.ToString() },
        { "str.Format", n => string.Format("{0}", value) },
        { "str.Concat", n => string.Concat(value) },
        { "string +", n => "" + value },
        { "Convert", n => Convert.ToString(value) },
    }.Vs();
}

Probably important to point out that Convert.ToString(...) will retain a null string.

Also it'd work to just specify ifelse() twice:

plot(pos,cn, col= ifelse(cn >= 3, "red", ifelse(cn <= 1,"blue", "black")), ylim = c(0, 10))

If you're sure it'll parse correctly, use

int.Parse(string)

If you're not, use

int i;
bool success = int.TryParse(string, out i);

Caution! In the case below, i will equal 0, not 10 after the TryParse.

int i = 10;
bool failure = int.TryParse("asdf", out i);

This is because TryParse uses an out parameter, not a ref parameter.

In Oracle, This work for me

SELECT name, min(date), min(time)
    FROM table_name
GROUP BY name

One statement can be written as such:

someValues.forEach(x => console.log(x));

or multiple statements can be enclosed in {} like this:

someValues.forEach(x => { let a = 2 + x; console.log(a); });

Use brackets to group the OR statements.

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND (date='$Date_Today' OR date='$Date_Yesterday' OR date='$Date_TwoDaysAgo' OR date='$Date_ThreeDaysAgo' OR date='$Date_FourDaysAgo' OR date='$Date_FiveDaysAgo' OR date='$Date_SixDaysAgo' OR date='$Date_SevenDaysAgo')");

You can also use IN

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND date IN ('$Date_Today','$Date_Yesterday','$Date_TwoDaysAgo','$Date_ThreeDaysAgo','$Date_FourDaysAgo','$Date_FiveDaysAgo','$Date_SixDaysAgo','$Date_SevenDaysAgo')");

You can use numpy.ravel to return a flattened array from n-dimensional array:

>>> a
array([[0, 1, 2],
       [3, 4, 5],
       [6, 7, 8]])
>>> a.ravel()
array([0, 1, 2, 3, 4, 5, 6, 7, 8])

Technically, the char* is not an array, but a pointer to a char.

Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of chars, or an array of strings.

One solution could be to reshape the date from wide to long putting all the departments in one column and counts in another, group by the employer id (in this case, the row number), and then filter to the department(s) with the max value. There are a couple of options for handling ties with this approach too.

library(tidyverse)

# sample data frame with a tie
df <- data_frame(V1=c(2,8,1),V2=c(7,3,5),V3=c(9,6,5))

df %>% 
  rownames_to_column('id') %>%  # creates an ID number
  gather(dept, cnt, V1:V3) %>% 
  group_by(id) %>% 
  slice(which.max(cnt))

  gather(dept, cnt, V1:V3) %>%

# If you're worried about ties, but only want a certain department, you could use rank() and choose 'first' or 'last'
df %>% 
  rownames_to_column('id') %>%
  gather(dept, cnt, V1:V3) %>% 
  group_by(id) %>% 
  mutate(dept_rank  = rank(-cnt, ties.method = "first")) %>% # or 'last'

We can alter multiple columns in a single query like this:

ALTER TABLE `tblcommodityOHLC`
    CHANGE COLUMN `updated_on` `updated_on` DATETIME NULL DEFAULT NULL AFTER `updated_by`,
    CHANGE COLUMN `delivery_datetime` `delivery_datetime` DATETIME NULL DEFAULT CURRENT_TIMESTAMP AFTER `delivery_status`;

Just give the queries as comma separated.

session.query().with_entities(SomeModel.col1)

is the same as

session.query(SomeModel.col1)

for alias, we can use .label()

session.query(SomeModel.col1.label('some alias name'))

why do these two different operators, [ ], and [[ ]], return the same result?

x = list(1, 2, 3, 4)

1. [ ] provides sub setting operation. In general sub set of any object will have the same type as the original object. Therefore, x[1] provides a list. Similarly x[1:2] is a subset of original list, therefore it is a list. Ex.

   x[1:2]
   
   [[1]] [1] 1
   
   [[2]] [1] 2
   

2. [[ ]] is for extracting an element from the list. x[[1]] is valid and extract the first element from the list. x[[1:2]] is not valid as [[ ]] does not provide sub setting like [ ].

    x[[2]] [1] 2 
   
   > x[[2:3]] Error in x[[2:3]] : subscript out of bounds
   

Though The above answers are right, I found something more user-friendly approach while using ternary operator.

{{ attachment in item['Attachments'][0] ? 'y' : 'n' }}

If someone need to work through foreach then,

{% for attachment in attachments %}
    {{ attachment in item['Attachments'][0] ? 'y' : 'n' }}
{% endfor %}

Default props with class component

Using static defaultProps is correct. You should also be using interfaces, not classes, for the props and state.

Update 2018/12/1: TypeScript has improved the type-checking related to defaultProps over time. Read on for latest and greatest usage down to older usages and issues.

For TypeScript 3.0 and up

TypeScript specifically added support for defaultProps to make type-checking work how you'd expect. Example:

interface PageProps {
  foo: string;
  bar: string;
}

export class PageComponent extends React.Component<PageProps, {}> {
    public static defaultProps = {
        foo: "default"
    };

    public render(): JSX.Element {
        return (
            <span>Hello, { this.props.foo.toUpperCase() }</span>
        );
    }
}

Which can be rendered and compile without passing a foo attribute:

<PageComponent bar={ "hello" } />

Note that:

• foo is not marked optional (ie foo?: string) even though it's not required as a JSX attribute. Marking as optional would mean that it could be undefined, but in fact it never will be undefined because defaultProps provides a default value. Think of it similar to how you can mark a function parameter optional, or with a default value, but not both, yet both mean the call doesn't need to specify a value. TypeScript 3.0+ treats defaultProps in a similar way, which is really cool for React users!
• The defaultProps has no explicit type annotation. Its type is inferred and used by the compiler to determine which JSX attributes are required. You could use defaultProps: Pick<PageProps, "foo"> to ensure defaultProps matches a sub-set of PageProps. More on this caveat is explained here.
• This requires @types/react version 16.4.11 to work properly.

For TypeScript 2.1 until 3.0

Before TypeScript 3.0 implemented compiler support for defaultProps you could still make use of it, and it worked 100% with React at runtime, but since TypeScript only considered props when checking for JSX attributes you'd have to mark props that have defaults as optional with ?. Example:

interface PageProps {
    foo?: string;
    bar: number;
}

export class PageComponent extends React.Component<PageProps, {}> {
    public static defaultProps: Partial<PageProps> = {
        foo: "default"
    };

    public render(): JSX.Element {
        return (
            <span>Hello, world</span>
        );
    }
}

Note that:

• It's a good idea to annotate defaultProps with Partial<> so that it type-checks against your props, but you don't have to supply every required property with a default value, which makes no sense since required properties should never need a default.
• When using strictNullChecks the value of this.props.foo will be possibly undefined and require a non-null assertion (ie this.props.foo!) or type-guard (ie if (this.props.foo) ...) to remove undefined. This is annoying since the default prop value means it actually will never be undefined, but TS didn't understand this flow. That's one of the main reasons TS 3.0 added explicit support for defaultProps.

Before TypeScript 2.1

This works the same but you don't have Partial types, so just omit Partial<> and either supply default values for all required props (even though those defaults will never be used) or omit the explicit type annotation completely.

Default props with Functional Components

You can use defaultProps on function components as well, but you have to type your function to the FunctionComponent (StatelessComponent in @types/react before version 16.7.2) interface so that TypeScript knows about defaultProps on the function:

interface PageProps {
  foo?: string;
  bar: number;
}

const PageComponent: FunctionComponent<PageProps> = (props) => {
  return (
    <span>Hello, {props.foo}, {props.bar}</span>
  );
};

PageComponent.defaultProps = {
  foo: "default"
};

Note that you don't have to use Partial<PageProps> anywhere because FunctionComponent.defaultProps is already specified as a partial in TS 2.1+.

Another nice alternative (this is what I use) is to destructure your props parameters and assign default values directly:

const PageComponent: FunctionComponent<PageProps> = ({foo = "default", bar}) => {
  return (
    <span>Hello, {foo}, {bar}</span>
  );
};

Then you don't need the defaultProps at all! Be aware that if you do provide defaultProps on a function component it will take precedence over default parameter values, because React will always explicitly pass the defaultProps values (so the parameters are never undefined, thus the default parameter is never used.) So you'd use one or the other, not both.

Read the "Parameter Expansion" section of the bash man page. Parameter expansion doesn't provide a general test for a variable being set, but there are several things you can do to a parameter if it isn't set.

For example:

function a {
    first_arg=${1-foo}
    # rest of the function
}

will set first_arg equal to $1 if it is assigned, otherwise it uses the value "foo". If a absolutely must take a single parameter, and no good default exists, you can exit with an error message when no parameter is given:

function a {
    : ${1?a must take a single argument}
    # rest of the function
}

(Note the use of : as a null command, which just expands the values of its arguments. We don't want to do anything with $1 in this example, just exit if it isn't set)

Wow, some solutions can get complicated! If you don't mind using a simple global, just take advantage of the fact that the input button click event fires first. One could further filter the $('input') selector for one of many forms by using $('#myForm input').

    $(document).ready(function(){
      var clkBtn = "";
      $('input[type="submit"]').click(function(evt) {
        clkBtn = evt.target.id;
      });

      $("#myForm").submit(function(evt) {
        var btnID = clkBtn;
        alert("form submitted; button id=" + btnID);
      });
    });

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

Special Parameters

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

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

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

When working with graphical user interfaces, you need to remember that drawing on a pane is done in the Java AWT/Swing event queue. You can't just use the Graphics object outside the paint()/paintComponent()/etc. methods.

However, you can use a technique called "Frame buffering". Basically, you need to have a BufferedImage and draw directly on it (see it's createGraphics() method; that graphics context you can keep and reuse for multiple operations on a same BufferedImage instance, no need to recreate it all the time, only when creating a new instance). Then, in your JPanel's paintComponent(), you simply need to draw the BufferedImage instance unto the JPanel. Using this technique, you can perform zoom, translation and rotation operations quite easily through affine transformations.

I use a polyfill that seem to do a good job.

I encountered the same issue and was able to fix it by:

1. Copy the folder to another place.
2. Delete .svn from copied folder
3. Right click the original folder and select 'SVN Checkout'
4. If you can't find (3), then your case is different than mine.
5. See if the directory on the REPO-BROWSER is correct. For my case, this was the cause.
6. Check out
7. Get back the files from the copied folder into the original directory.
8. Commit.

Although it is much easier to restore database using SSMS as stated in many answers. You can also restore Database using .bak with SQL server query, for example

RESTORE DATABASE AdventureWorks2012 FROM DISK = 'D:\AdventureWorks2012.BAK'
GO

In above Query you need to keep in mind about .mdf/.ldf file location. You might get error

System.Data.SqlClient.SqlError: Directory lookup for the file "C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\MSSQL\DATA\AdventureWorks.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.SmoExtended)

So you need to run Query as below

RESTORE FILELISTONLY 
FROM DISK = 'D:\AdventureWorks2012.BAK'

Once you will run above Query you will get location of mdf/ldf use it Restore database using query

USE MASTER
GO
RESTORE DATABASE DBASE 
FROM DISK = 'D:\AdventureWorks2012.BAK'
WITH 
MOVE 'DBASE' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE.MDF',
MOVE 'DBASE_LOG' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE_1.LDF', 
NOUNLOAD,  REPLACE,  NOUNLOAD,  STATS = 5
GO

I'm running Windows 7 with git bash console. The above commands wouldn't work for me.

So I did it via Windows Explorer. I checked show hidden files, went to my projects directory and manually deleted the .git folder. Then back in the command line I checked by running git status.

Which returned...

fatal: Not a git repository (or any of the parent directories): .git

Which is exactly the result I wanted. It returned that the directory is not a git repository (anymore!).

One method is:

tar -cf my_archive.tar $( find -name "*.php" -or -name "*.html" )

There are some caveats with this method however:

1. It will fail if there are any files or directories with spaces in them, and
2. it will fail if there are so many files that the maximum command line length is full.

A workaround to these could be to output the contents of the find command into a file, and then use the "-T, --files-from FILE" option to tar.

I had the same $count variable in a while loop getting lost issue.

@fedorqui's answer (and a few others) are accurate answers to the actual question: the sub-shell is indeed the problem.

But it lead me to another issue: I wasn't piping a file content... but the output of a series of pipes & greps...

my erroring sample code:

count=0
cat /etc/hosts | head | while read line; do
  ((count++))
  echo $count $line
done
echo $count

and my fix thanks to the help of this thread and the process substitution:

count=0
while IFS= read -r line; do
  ((count++))
  echo "$count $line"
done < <(cat /etc/hosts | head)
echo "$count"

First create public folder under resources and create index.html file. Use WebMvcConfigurer instead of WebMvcConfigurerAdapter.

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebAppConfig implements WebMvcConfigurer {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("forward:/index.html");
    }

}

I've reduced your code sample to the following lines to make it easier to understand the explanation of the concept.

var results = [];
var config = JSON.parse(queries);
for (var key in config) {
    var query = config[key].query;
    search(query, function(result) {
        results.push(result);
    });
}
res.writeHead( ... );
res.end(results);

The problem with the previous code is that the search function is asynchronous, so when the loop has ended, none of the callback functions have been called. Consequently, the list of results is empty.

To fix the problem, you have to put the code after the loop in the callback function.

    search(query, function(result) {
        results.push(result);
        // Put res.writeHead( ... ) and res.end(results) here
    });

However, since the callback function is called multiple times (once for every iteration), you need to somehow know that all callbacks have been called. To do that, you need to count the number of callbacks, and check whether the number is equal to the number of asynchronous function calls.

To get a list of all keys, use Object.keys. Then, to iterate through this list, I use .forEach (you can also use for (var i = 0, key = keys[i]; i < keys.length; ++i) { .. }, but that could give problems, see JavaScript closure inside loops – simple practical example).

Here's a complete example:

var results = [];
var config = JSON.parse(queries);
var onComplete = function() {
    res.writeHead( ... );
    res.end(results);
};
var keys = Object.keys(config);
var tasksToGo = keys.length;
if (tasksToGo === 0) {
   onComplete();
} else {
    // There is at least one element, so the callback will be called.
    keys.forEach(function(key) {
        var query = config[key].query;
        search(query, function(result) {
            results.push(result);
            if (--tasksToGo === 0) {
                // No tasks left, good to go
                onComplete();
            }
        });
    });
}

Note: The asynchronous code in the previous example are executed in parallel. If the functions need to be called in a specific order, then you can use recursion to get the desired effect:

var results = [];
var config = JSON.parse(queries);
var keys = Object.keys(config);
(function next(index) {
    if (index === keys.length) { // No items left
        res.writeHead( ... );
        res.end(results);
        return;
    }
    var key = keys[index];
    var query = config[key].query;
    search(query, function(result) {
        results.push(result);
        next(index + 1);
    });
})(0);

What I've shown are the concepts, you could use one of the many (third-party) NodeJS modules in your implementation, such as async.

While the answer given by Paul H shows the essential part, it is not a complete example. On the other hand the matplotlib example seems rather complicated and does not show how to use days.

So for everyone in need here is a full working example:

from datetime import datetime

from matplotlib.dates import DateFormatter

myDates = [datetime(2012,1,i+3) for i in range(10)]
myValues = [5,6,4,3,7,8,1,2,5,4]
fig, ax = plt.subplots()

public static object GetProperty(object target, string name)
{
    var site = System.Runtime.CompilerServices.CallSite<Func<System.Runtime.CompilerServices.CallSite, object, object>>.Create(Microsoft.CSharp.RuntimeBinder.Binder.GetMember(0, name, target.GetType(), new[]{Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create(0,null)}));
    return site.Target(site, target);
}

Add reference to Microsoft.CSharp. Works also for dynamic types and private properties and fields.

Edit: While this approach works, there is almost 20× faster method from the Microsoft.VisualBasic.dll assembly:

public static object GetProperty(object target, string name)
{
    return Microsoft.VisualBasic.CompilerServices.Versioned.CallByName(target, name, CallType.Get);
}

I play with following

extension String {
    func allCharactes() -> [Character] {
         var result: [Character] = []
         for c in self.characters {
             result.append(c)
         }
         return 
    }
}

until I understand the provided one's now it's just Character array

and with

let c = Array(str.characters)

Using jquery and css :

$("#element").click(function(){ 
    $(this).addClass("wait");
});?

HTML: <div id="element">Click and wait</div>?

CSS: .wait {cursor:wait}?

I recently stuck in with this error while building my containerized jar applications with Bamboo:

org.apache.maven.surefire.booter.SurefireBooterForkException: The forked VM terminated without properly saying goodbye

After many hours of researching I fixed it. And I thought it would be useful to share my solution here.

So the error happen every time when bamboo run mvn clean package command for java applications in the docker containers. I am no Maven expert but the trouble was in Surefire and Junit4 plugins included in spring-boot as maven dependency.

To fix it you need to replace Junit4 for Junit5 and override Surefire plugin in you pom.xml.

1.Inside spring boot dependency insert exclusion:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <!-- FIX BAMBOO DEPLOY>
    <exclusions>
        <exclusion>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </exclusion>
    </exclusions>
    <!---->
</dependency>

2. Add new Junit5 dependencies:

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.1.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.vintage</groupId>
    <artifactId>junit-vintage-engine</artifactId>
    <version>5.1.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-launcher</artifactId>
    <version>1.1.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-runner</artifactId>
    <version>1.1.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-surefire-provider</artifactId>
    <version>1.1.0</version>
    <scope>test</scope>
</dependency>

3. Insert new plugin inside plugins section

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <dependencies>
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>1.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.1.0</version>
        </dependency>
    </dependencies>
</plugin>

That's should be enough to repair bamboo builds. Don't forget also transform all Junit4 tests to support Junit5.

For an ArrayAdapter, notifyDataSetChanged only works if you use the add(), insert(), remove(), and clear() on the Adapter.

When an ArrayAdapter is constructed, it holds the reference for the List that was passed in. If you were to pass in a List that was a member of an Activity, and change that Activity member later, the ArrayAdapter is still holding a reference to the original List. The Adapter does not know you changed the List in the Activity.

Your choices are:

1. Use the functions of the ArrayAdapter to modify the underlying List (add(), insert(), remove(), clear(), etc.)
2. Re-create the ArrayAdapter with the new List data. (Uses a lot of resources and garbage collection.)
3. Create your own class derived from BaseAdapter and ListAdapter that allows changing of the underlying List data structure.
4. Use the notifyDataSetChanged() every time the list is updated. To call it on the UI-Thread, use the runOnUiThread() of Activity. Then, notifyDataSetChanged() will work.

JAR File Manifest Attributes for Security

The JAR file manifest contains information about the contents of the JAR file, including security and configuration information.

Add the attributes to the manifest before the JAR file is signed.
See Modifying a Manifest File in the Java Tutorial for information on adding attributes to the JAR manifest file.

Permissions Attribute

The Permissions attribute is used to verify that the permissions level requested by the RIA when it runs matches the permissions level that was set when the JAR file was created.

Use this attribute to help prevent someone from re-deploying an application that is signed with your certificate and running it at a different privilege level. Set this attribute to one of the following values:

• sandbox - runs in the security sandbox and does not require additional permissions.

• all-permissions - requires access to the user's system resources.

Changes to Security Slider:

The following changes to Security Slider were included in this release(7u51):

• Block Self-Signed and Unsigned applets on High Security Setting
• Require Permissions Attribute for High Security Setting
• Warn users of missing Permissions Attributes for Medium Security Setting

For more information, see Java Control Panel documentation.

FYI Dark theme is now in the Dev Version of MySQL Workbench

Update: From what I can tell it is Natively built into MySQL Workbench 8.0.15 for MAC OS X

The package I downloaded was mysql-workbench-community-8.0.15-macos-x86_64.dmg

https://dev.mysql.com/downloads/workbench/

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

1) Update Devise so that it can handle Rails 4.0 by adding this line to your application's Gemfile:

gem 'devise', '3.0.0.rc' 

Then execute:

$ bundle

2) Add the old functionality of attr_accessible again to rails 4.0

Try to use attr_accessible and don't comment this out.

Add this line to your application's Gemfile:

gem 'protected_attributes'

Then execute:

$ bundle

I added a reference to the .dll file, for System.Data.Linq, the above was not sufficient. You can find .dll in the various directories for the following versions.

System.Data.Linq C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Data.Linq.dll 3.5.0.0

System.Data.Linq C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\Profile\Client\System.Data.Linq.dll 4.0.0.0

The document looks fine to me but I suspect that it contains invisible characters. Open it in a hex editor to check that there really isn't anything before the very first "<". Make sure the spaces in the XML header are spaces. Maybe delete the space before "?>". Check which line breaks are used.

Make sure the document is proper UTF-8. Some windows editors save the document as UTF-16 (i.e. every second byte is 0).

Not even that complicated and no imports required in Java 7:

The renameTo( ) method changes the name of a file:

public boolean renameTo( File destination)

For example, to change the name of the file src.txt in the current working directory to dst.txt, you would write:

File src = new File(" src.txt"); File dst = new File(" dst.txt"); src.renameTo( dst); 

That's it.

Reference:

Harold, Elliotte Rusty (2006-05-16). Java I/O (p. 393). O'Reilly Media. Kindle Edition.

I would do something like this:

$.each(temp,function(key, value) 
{
    $select.append('<option value=' + key + '>' + value + '</option>');
});

JSON structure would be appreciated. At first you can experiment with find('element') - it depends on JSON.

Seems like just this works:

curl -I http://example.com

Look for Access-Control-Allow-Origin: * in the returned headers

((TextBox)GridView1.Rows[e.NewEditIndex].Cells[3].Controls[0]).Enabled = false;
