Following on @Anorak answer, i added this extension to String and sent an inset as a parameter, because a lot of times you will need a padding to your text. Anyway, maybe some you will find this usefull.

extension String {

    func heightForWithFont(font: UIFont, width: CGFloat, insets: UIEdgeInsets) -> CGFloat {

        let label:UILabel = UILabel(frame: CGRectMake(0, 0, width + insets.left + insets.right, CGFloat.max))
        label.numberOfLines = 0
        label.lineBreakMode = NSLineBreakMode.ByWordWrapping
        label.font = font
        label.text = self

        label.sizeToFit()
        return label.frame.height + insets.top + insets.bottom
    }
}

... or if you want / need to keep your option 'value' as it was, just add a new attribute:

<select id="my_selection">
<option value="x" href="/link/to/somewhere">value 1</option>
<option value="y" href="/link/to/somewhere/else">value 2</option>
</select>

<script>
document.getElementById('my_selection').onchange = function() {
    window.location.href = this.children[this.selectedIndex].getAttribute('href');
}
</script>

By default, when you are inside a function, you do not have access to the outer variables.

If you want your function to have access to an outer variable, you have to declare it as global, inside the function :

function someFuntion(){
    global $myArr;
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
}

For more informations, see Variable scope.

But note that using global variables is not a good practice : with this, your function is not independant anymore.

A better idea would be to make your function return the result :

function someFuntion(){
    $myArr = array();       // At first, you have an empty array
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;      // Put that $myVal into the array
    return $myArr;
}

And call the function like this :

$result = someFunction();

Your function could also take parameters, and even work on a parameter passed by reference :

function someFuntion(array & $myArr){
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;      // Put that $myVal into the array
}

Then, call the function like this :

$myArr = array( ... );
someFunction($myArr);  // The function will receive $myArr, and modify it

With this :

• Your function received the external array as a parameter
• And can modify it, as it's passed by reference.
• And it's better practice than using a global variable : your function is a unit, independant of any external code.

For more informations about that, you should read the Functions section of the PHP manual, and,, especially, the following sub-sections :

• Functions arguments
• Returning values

From API 19 onwards you can make use of the Telephony Class for that; Since hardcored values won't retrieve messages in every devices because the content provider Uri changes from devices and manufacturers.

public void getAllSms(Context context) {

    ContentResolver cr = context.getContentResolver();
    Cursor c = cr.query(Telephony.Sms.CONTENT_URI, null, null, null, null);
    int totalSMS = 0;
    if (c != null) {
        totalSMS = c.getCount();
        if (c.moveToFirst()) {
            for (int j = 0; j < totalSMS; j++) {
                String smsDate = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.DATE));
                String number = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.ADDRESS));
                String body = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.BODY));
                Date dateFormat= new Date(Long.valueOf(smsDate));
                String type;
                switch (Integer.parseInt(c.getString(c.getColumnIndexOrThrow(Telephony.Sms.TYPE)))) {
                    case Telephony.Sms.MESSAGE_TYPE_INBOX:
                        type = "inbox";
                        break;
                    case Telephony.Sms.MESSAGE_TYPE_SENT:
                        type = "sent";
                        break;
                    case Telephony.Sms.MESSAGE_TYPE_OUTBOX:
                        type = "outbox";
                        break;
                    default:
                        break;
                }


                c.moveToNext();
            }
        }

        c.close();

    } else {
        Toast.makeText(this, "No message to show!", Toast.LENGTH_SHORT).show();
    }
}

In your /etc/nginx/nginx.conf file you have:

include /etc/nginx/site-enabled/*;

And probably the path you are using is:

/etc/nginx/sites-enabled/default

Notice the missing s in site.

Explicit pass-through

Similar to nesting the callbacks, this technique relies on closures. Yet, the chain stays flat - instead of passing only the latest result, some state object is passed for every step. These state objects accumulate the results of the previous actions, handing down all values that will be needed later again plus the result of the current task.

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(b => [resultA, b]); // function(b) { return [resultA, b] }
    }).then(function([resultA, resultB]) {
        // more processing
        return // something using both resultA and resultB
    });
}

Here, that little arrow b => [resultA, b] is the function that closes over resultA, and passes an array of both results to the next step. Which uses parameter destructuring syntax to break it up in single variables again.

Before destructuring became available with ES6, a nifty helper method called .spread() was pro­vi­ded by many promise libraries (Q, Bluebird, when, …). It takes a function with multiple parameters - one for each array element - to be used as .spread(function(resultA, resultB) { ….

Of course, that closure needed here can be further simplified by some helper functions, e.g.

function addTo(x) {
    // imagine complex `arguments` fiddling or anything that helps usability
    // but you get the idea with this simple one:
    return res => [x, res];
}

…
return promiseB(…).then(addTo(resultA));

Alternatively, you can employ Promise.all to produce the promise for the array:

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return Promise.all([resultA, promiseB(…)]); // resultA will implicitly be wrapped
                                                    // as if passed to Promise.resolve()
    }).then(function([resultA, resultB]) {
        // more processing
        return // something using both resultA and resultB
    });
}

And you might not only use arrays, but arbitrarily complex objects. For example, with _.extend or Object.assign in a different helper function:

function augment(obj, name) {
    return function (res) { var r = Object.assign({}, obj); r[name] = res; return r; };
}

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(augment({resultA}, "resultB"));
    }).then(function(obj) {
        // more processing
        return // something using both obj.resultA and obj.resultB
    });
}

While this pattern guarantees a flat chain and explicit state objects can improve clarity, it will become tedious for a long chain. Especially when you need the state only sporadically, you still have to pass it through every step. With this fixed interface, the single callbacks in the chain are rather tightly coupled and inflexible to change. It makes factoring out single steps harder, and callbacks cannot be supplied directly from other modules - they always need to be wrapped in boilerplate code that cares about the state. Abstract helper functions like the above can ease the pain a bit, but it will always be present.

In some instances, using fall-throughs is an act of laziness on the part of the programmer - they could use a series of || statements, for example, but instead use a series of 'catch-all' switch cases.

That being said, I've found them to be especially helpful when I know that eventually I'm going to need the options anyway (for example in a menu response), but have not yet implemented all the choices. Likewise, if you're doing a fall-through for both 'a' and 'A', I find it substantially cleaner to use the switch fall-through than a compound if statement.

It's probably a matter of style and how the programmers think, but I'm not generally fond of removing components of a language in the name of 'safety' - which is why I tend towards C and its variants/descendants more than, say, Java. I like being able to monkey-around with pointers and the like, even when I have no "reason" to.

You can only use

     Object& return_Object();

if the object returned has a greater scope than the function. For example, you can use it if you have a class where it is encapsulated. If you create an object in your function, use pointers. If you want to modify an existing object, pass it as an argument.

  class  MyClass{
      private:
        Object myObj;

      public:
         Object& return_Object() {
            return myObj;
         }

         Object* return_created_Object() {
            return new Object();
         }

         bool modify_Object( Object& obj) {
            //  obj = myObj; return true; both possible
            return obj.modifySomething() == true;
         }
   };

Let the resolver automatically do that.

Inside A controller:

public class AController : ApiController
{
    private readonly BController _bController;

    public AController(
    BController bController)
    {
        _bController = bController;
    }

    public httpMethod{
    var result =  _bController.OtherMethodBController(parameters);
    ....
    }

}

Using jQuery:

 $('#link_other a').each(function(){
  $(this).attr('target', '_BLANK');
 });

you can use the below css styles for all browsers except Firefox 30

select {
  background: url(dropdown_arw.png) no-repeat right center;
  appearance: none;
  -moz-appearance: none;
  -webkit-appearance: none;
  width: 90px;
  text-indent: 0.01px;
  text-overflow: "";
}

For whatever reason, I noticed that setting to unicode for "All Configurations" did not actually apply to all configurations.

Picture:

To confirm this, I would open the .vcxproj and confirm the correct token is in all 4 locations. In this photo, I am using unicode. So the string I am looking for is "Unicode". For you, you likely want it to say "MultiByte".

Picture:

DateTime? d=null;
DateTime d2;
bool success = DateTime.TryParse("some date text", out d2);
if (success) d=d2;

(There might be more elegant solutions, but why don't you simply do something as above?)

Building on @peter-olson's answer, I took a more object oriented approach without jQuery:

String.prototype.ucwords = function() {
    return this.toLowerCase().replace(/\b[a-z]/g, function(letter) {
        return letter.toUpperCase();
    });
}

alert("hello world".ucwords()); //Displays "Hello World"

Example: http://jsfiddle.net/LzaYH/1/

As stated,

innodb_buffer_pool_size=50M

Following the convention on the other predefined variables, make sure there is no space either side of the equals sign.

Then run

sudo service mysqld stop
sudo service mysqld start

Note

Sometimes, e.g. on Ubuntu, the MySQL daemon is named mysql as opposed to mysqld

I find that running /etc/init.d/mysqld restart doesn't always work and you may get an error like

Stopping mysqld:                                           [FAILED]
Starting mysqld:                                           [  OK  ]

To see if the variable has been set, run show variables and see if the value has been updated.

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

mvn eclipse:eclipse -DdownloadSources=true

or

mvn eclipse:eclipse -DdownloadJavadocs=true

or you can add both flags, as Spencer K points out.

Additionally, the =true portion is not required, so you can use

mvn eclipse:eclipse -DdownloadSources -DdownloadJavadocs

You need to make the strings raw and use latex:

fig.gca().set_ylabel(r'$\lambda$')

As of matplotlib 2.0 the default font supports most western alphabets and can simple do

ax.set_xlabel('?')

with unicode.

"A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered."

Not so. The purpose of a destructor is to allow the item that registered the listeners to unregister them. Once an object has no other references to it, it will be garbage collected.

For instance, in AngularJS, when a controller is destroyed, it can listen for a destroy event and respond to it. This isn't the same as having a destructor automatically called, but it's close, and gives us the opportunity to remove listeners that were set when the controller was initialized.

// Set event listeners, hanging onto the returned listener removal functions
function initialize() {
    $scope.listenerCleanup = [];
    $scope.listenerCleanup.push( $scope.$on( EVENTS.DESTROY, instance.onDestroy) );
    $scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.SUCCESS, instance.onCreateUserResponse ) );
    $scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.FAILURE, instance.onCreateUserResponse ) );
}

// Remove event listeners when the controller is destroyed
function onDestroy(){
    $scope.listenerCleanup.forEach( remove => remove() );
}

You can check an optionally passed flag with store_true and store_false argument action options:

import argparse

argparser = argparse.ArgumentParser()
argparser.add_argument('-flag', dest='flag_exists', action='store_true')

print argparser.parse_args([])
# Namespace(flag_exists=False)
print argparser.parse_args(['-flag'])
# Namespace(flag_exists=True)

This way, you don't have to worry about checking by conditional is not None. You simply check for True or False. Read more about these options in the docs here

This can help you

namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
imshow( "Display window", image );                   // Show our image inside it.

Given that canvas is nothing without JavaScript, use JavaScript too for sizing and positionning (you know: onresize, position:absolute, etc.)

After upgrading to Angular 9 (released today), I ran into this issue as well and found that they made the breaking change mentioned in the answer. I can't find a reason for why they made this change.

I have a material.module.ts file that I import / export all the material components (not the most efficient, but useful for quick development). I went through and updated all my imports to the individual material folders, although an index.ts barrel might be better. Again, not sure why they made this change, but I'm guessing it has to do with tree-shaking efficiencies.

Including my material.module.ts below in case it helps anyone, it's inspired off other material modules I've found:

NOTE: As other blog posts have mentioned and from my personal experience, be careful when using a shared module like below. I have 5~ different feature modules (lazy loaded) in my app that I imported my material module into. Out of curiosity, I stopped using the shared module and instead only imported the individual material components each feature module needed. This reduced my bundle size quite a bit, almost a 200kb reduction. I assumed that the build optimization process would properly drop any component not used by my modules, but it doesn't seem to be the case...

You can use flexbox for this.

ul {
    display: flex;
    align-items: center;
}

A detailed explanation of how to use flexbox can be found here.

I found a possible answer here: http://web.archive.org/web/20130329123237/http://www.csharpfriends.com/Articles/getArticle.aspx?articleID=63

From the article:

XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslTransform myXslTrans = new XslTransform() ;
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null) ;
myXslTrans.Transform(myXPathDoc,null,myWriter) ;

Edit:

But my trusty compiler says, XslTransform is obsolete: Use XslCompiledTransform instead:

XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslCompiledTransform myXslTrans = new XslCompiledTransform();
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null);
myXslTrans.Transform(myXPathDoc,null,myWriter);

Just use setTimeOut with recursion:

waitUntilElementIsPresent(callback: () => void): void {
    if (!this.methodToCheckIfElementIsPresent()) {
        setTimeout(() => this.waitUntilElementIsPresent(callback), 500);
        return;
    }
    callback();
}

Usage:

this.waitUntilElementIsPresent(() => console.log('Element is present!'));

You can limit amount of attempts, so an error will be thrown when the element is not present after the limit:

waitUntilElementIsPresent(callback: () => void, attempt: number = 0): void {
    const maxAttempts = 10;
    if (!this.methodToCheckIfElementIsPresent()) {
        attempt++;
        setTimeout(() => this.waitUntilElementIsPresent(callback, attempt), 500);
        return;
    } else if (attempt >= maxAttempts) {
        return;
    }
    callback();
}

If you are exporting another class in that module, make sure that it is not in between @Component and your ClassComponent. For example:

@Component({ ... })

export class ExampleClass{}

export class ComponentClass{}  --> this will give this error.

FIX:

export class ExampleClass{}

@Component ({ ... })

export class ComponentClass{}

The best way around this is (and many other situations) in my experience, is to use cntlm which is a local no-authentication proxy which points to a remote authentication proxy. You can then just set WinHTTP to point to your local CNTLM (usually localhost:3128), and you can set CNTLM itself to point to the remote authentication proxy. CNTLM has a "magic NTLM dialect detection" option which generates password hashes to be put into the CNTLM configuration files.

To revert a merge commit, you need to use: git revert -m <parent number>. So for example, to revert the recent most merge commit using the parent with number 1 you would use:

git revert -m 1 HEAD

To revert a merge commit before the last commit, you would do:

git revert -m 1 HEAD^

Use git show <merge commit SHA1> to see the parents, the numbering is the order they appear e.g. Merge: e4c54b3 4725ad2

This is all perfectly normal. Microsoft added sequences in SQL Server 2012, finally, i might add and changed the way identity keys are generated. Have a look here for some explanation.

If you want to have the old behaviour, you can:

1. use trace flag 272 - this will cause a log record to be generated for each generated identity value. The performance of identity generation may be impacted by turning on this trace flag.
2. use a sequence generator with the NO CACHE setting (http://msdn.microsoft.com/en-us/library/ff878091.aspx)

building on @ltamar's answer:
Use summary and munge the output into something useful!

library(tidyr)
library(dplyr)

df %>% 
  summary %>% 
  data.frame %>%
  select(-Var1) %>%
  separate(data=.,col=Freq,into = c('metric','value'),sep = ':') %>%
  rename(column_name=Var2) %>%
  mutate(value=as.numeric(value),
         metric = trimws(metric,'both') 
  ) %>%  
  filter(!is.na(value)) -> metrics

It's not pretty and it is certainly not fast but it gets the job done!

You can change the background of the canvas by doing this:

<head>
    <style>
        canvas {
            background-color: blue;
        }
    </style>
</head>

This will do what you want:

<?php

$array = array(2 => 'a', 1 => 'b', 0 => 'c');

array_unshift($array, false); // Add to the start of the array
$array = array_values($array); // Re-number

// Remove the first index so we start at 1
$array = array_slice($array, 1, count($array), true);

print_r($array); // Array ( [1] => a [2] => b [3] => c ) 

?>

Just solved the issue. After digging around for a while longer, I found this SO post which covers the exact same situation. It got me in the right track.

Basically, the XmlSerializer needs to know the default namespace if derived classes are included as extra types. The exact reason why this has to happen is still unknown but, still, serialization is working now.

I have a feeling that most answers here overcomplicate the simple problem. If you already understand how the map works that should be fairly easy to grasp.

There are cases where we can end up with unwanted nested structures when using map(), the flatMap() method is designed to overcome this by avoiding wrapping.

Examples:

1

List<List<Integer>> result = Stream.of(Arrays.asList(1), Arrays.asList(2, 3))
  .collect(Collectors.toList());

We can avoid having nested lists by using flatMap:

List<Integer> result = Stream.of(Arrays.asList(1), Arrays.asList(2, 3))
  .flatMap(i -> i.stream())
  .collect(Collectors.toList());

2

Optional<Optional<String>> result = Optional.of(42)
      .map(id -> findById(id));

Optional<String> result = Optional.of(42)
      .flatMap(id -> findById(id));

where:

private Optional<String> findById(Integer id)

What about normal encoded white-space character?

 

Cudos accepted answer is great. However, the Draggable module also has a "drag" event that tells you the position while your dragging. So, in addition to the 'start' and 'stop' you could add the following event within your Draggable object:

    // Drag current position of dragged image.
    drag: function(event, ui) {

        // Show the current dragged position of image
        var currentPos = $(this).position();
        $("div#xpos").text("CURRENT: \nLeft: " + currentPos.left + "\nTop: " + currentPos.top);

    }

A threadpool with no dependencies outside of STL is entirely possible. I recently wrote a small header-only threadpool library to address the exact same problem. It supports dynamic pool resizing (changing the number of workers at runtime), waiting, stopping, pausing, resuming and so on. I hope you find it useful.

OPTIMIZE TABLE works fine with InnoDB engine according to the official support article : http://dev.mysql.com/doc/refman/5.5/en/optimize-table.html

You'll notice that optimize InnoDB tables will rebuild table structure and update index statistics (something like ALTER TABLE).

Keep in mind that this message could be an informational mention only and the very important information is the status of your query : just OK !

mysql> OPTIMIZE TABLE foo;
+----------+----------+----------+-------------------------------------------------------------------+
| Table    | Op       | Msg_type | Msg_text                                                          |
+----------+----------+----------+-------------------------------------------------------------------+

As best I can tell, it is not possible to update the select2 options without refreshing the entire list or entering some search text and using a query function.

What are those buttons supposed to do? If they are used to determine the select options, why not put them outside of the select box, and have them programmatically set the select box data and then open it? I don't understand why you would want to put them on top of the search box. If the user is not supposed to search, you can use the minimumResultsForSearch option to hide the search feature.

Edit: How about this...

HTML:

<input type="hidden" id="select2" class="select" />

Javascript

var data = [{id: 0, text: "Zero"}],
    select = $('#select2');

select.select2({
  query: function(query) {
    query.callback({results: data});
  },
  width: '150px'
});

console.log('Opening select2...');
select.select2('open');

setTimeout(function() {
  console.log('Updating data...');
  data = [{id: 1, text: 'One'}];
}, 1500);

setTimeout(function() {
  console.log('Fake keyup-change...');
  select.data().select2.search.trigger('keyup-change');
}, 3000);

Example: Plunker

Edit 2: That will at least get it to update the list, however there is still some weirdness if you have entered search text before triggering the keyup-change event.

It prints 47.48000 if you use another MathContext:

BigDecimal b = new BigDecimal(d, MathContext.DECIMAL64);

Just pick the context you need.

The answer of Pardeep Jain can be useful for static data, but what if we have an array in JSON?

For example, we have i values and get the value of id field

alert(obj[i].id); //works!

But what if we need key with spaces?

In this case, the following construction can help (without point between [] blocks):

alert(obj[i]["No. of interfaces"]); //works too!

This simple problem can cause a real headache!

I can see your controller EDIT (PUT) method expects 2 parameters: a) an int id, and b) a department object.

It is the default code when you generate this from VS > add controller with read/write options. However, you have to remember to consume this service using the two parameters, otherwise you will get the error 405.

In my case, I did not need the id parameter for PUT, so I just dropped it from the header... after a few hours of not noticing it there! If you keep it there, then the name must also be retained as id, unless you go on to make necessary changes to your configurations.

Sybase has the same case syntax as SQL Server:

Description

Supports conditional SQL expressions; can be used anywhere a value expression can be used.

Syntax

case 
     when search_condition then expression 
    [when search_condition then expression]...
    [else expression]
end

Case and values syntax

case expression
     when expression then expression 
    [when expression then expression]...
    [else expression]
end

Parameters

case

begins the case expression.

when

precedes the search condition or the expression to be compared.

search_condition

is used to set conditions for the results that are selected. Search conditions for case expressions are similar to the search conditions in a where clause. Search conditions are detailed in the Transact-SQL User’s Guide.

then

precedes the expression that specifies a result value of case.

expression

is a column name, a constant, a function, a subquery, or any combination of column names, constants, and functions connected by arithmetic or bitwise operators. For more information about expressions, see “Expressions” in.

Example

select disaster, 
       case
            when disaster = "earthquake" 
                then "stand in doorway"
            when disaster = "nuclear apocalypse" 
                then "hide in basement"
            when monster = "zombie apocalypse" 
                then "hide with Chuck Norris"
            else
                then "ask mom"
       end

You're using S_ISREG() and S_ISDIR() correctly, you're just using them on the wrong thing.

In your while((dit = readdir(dip)) != NULL) loop in main, you're calling stat on currentPath over and over again without changing currentPath:

if(stat(currentPath, &statbuf) == -1) {
    perror("stat");
    return errno;
}

Shouldn't you be appending a slash and dit->d_name to currentPath to get the full path to the file that you want to stat? Methinks that similar changes to your other stat calls are also needed.

Eclipse is recommending that you declare the type of the HashMap because that enforces some type safety. Of course, it sounds like you're trying to avoid type safety from your second part.

If you want to do the latter, try declaring map as HashMap<String,Object>.

If we write web.xml without ContextLoaderListener then we cant give the athuntication using customAuthenticationProvider in spring security. Because DispatcherServelet is the child context of ContextLoaderListener, customAuthenticationProvider is the part of parentContext that is ContextLoaderListener. So parent Context cannot have the dependencies of child context. And so it is best practice to write spring-context.xml in contextparam instead of write it in the initparam.

If anaconda is fully updated, a simple "conda init zsh" should work. Navigate into the anaconda3 folder using

cd /path/to/anaconda3/

of course replacing "/path/to/anaconda/" with "~/anaconda3" or "/anaconda3" or wherever the "anaconda3" folder is kept.

To make sure it's updated, run

./bin/conda update --prefix . anaconda

After this, running

./bin/conda init zsh

(or whatever shell you're using) will finish the job cleanly.

Phone numbers are hard. For a more robust, international solution, I would recommend this well-maintained PHP port of Google's libphonenumber library.

Using it like this,

use libphonenumber\NumberParseException;
use libphonenumber\PhoneNumber;
use libphonenumber\PhoneNumberFormat;
use libphonenumber\PhoneNumberUtil;

$phoneUtil = PhoneNumberUtil::getInstance();

$numberString = "+12123456789";

try {
    $numberPrototype = $phoneUtil->parse($numberString, "US");

    echo "Input: " .          $numberString . "\n";
    echo "isValid: " .       ($phoneUtil->isValidNumber($numberPrototype) ? "true" : "false") . "\n";
    echo "E164: " .           $phoneUtil->format($numberPrototype, PhoneNumberFormat::E164) . "\n";
    echo "National: " .       $phoneUtil->format($numberPrototype, PhoneNumberFormat::NATIONAL) . "\n";
    echo "International: " .  $phoneUtil->format($numberPrototype, PhoneNumberFormat::INTERNATIONAL) . "\n";
} catch (NumberParseException $e) {
    // handle any errors
}

you will get the following output:

Input: +12123456789
isValid: true
E164: +12123456789
National: (212) 345-6789
International: +1 212-345-6789

I'd recommend using the E164 format for duplicate checks. You could also check whether the number is a actually mobile number or not (using PhoneNumberUtil::getNumberType()), or whether it's even a US number (using PhoneNumberUtil::getRegionCodeForNumber()).

As a bonus, the library can handle pretty much any input. If you, for instance, choose to run 1-800-JETBLUE through the code above, you will get

Input: 1-800-JETBLUE
isValid: true
E164: +18005382583
National: (800) 538-2583
International: +1 800-538-2583

Neato.

It works just as nicely for countries other than the US. Just use another ISO country code in the parse() argument.

Update December 2012 (19 months later):

The blog post "Jin Mingjian: Eclipse Darker Theme" mentions this GitHub repo "eclipse themes - darker":

The big fun is that, the codes are minimized by using Eclipse4 platform technologies like dependency injection.
It proves that again, the concise codes and advanced features could be achieved by contributing or extending with the external form (like library, framework).
New language is not necessary just for this kind of purpose.

Update July 2012 (14 months later):

With the latest Eclipse4.2 (June 2012, "Juno") release, you can implement what I originally described below: a CSS-based fully dark theme for Eclipse.
See the article by Lars Vogel in "Eclipse 4 is beautiful – Create your own Eclipse 4 theme":

If you want to play with it, you only need to write a plug-in, create a CSS file and use the org.eclipse.e4.ui.css.swt.theme extension point to point to your file.
If you export your plug-in, place it in the “dropins” folder of your Eclipse installation and your styling is available.

Original answer: August 2011

With Eclipse 3.x, theme is only for the editors, as you can see in the site "Eclipse Color Themes".
Anything around that is managed by windows system colors.
That is what you need to change to have any influence on Eclipse global colors around editors.

Eclipse 4 will provide much advance theme options: See "Eclipse 4.0 – So you can theme me Part 1" and "Eclipse 4.0 RCP: Dynamic CSS Theme Switching".

Do not waste your time on checking integrity or deleting data from work queue table because these are temporary solutions and it will hit you back after a while.

Just do another checkout and replace the existing .svn folder with the new one. Do an update and then it should go smooth.

This problem occurred to me when using nested try- catch and using the $ex->getPrevious() function for logging exception .mabye your code has endless loop. So you first need to check the code and increase the size of the memory if necessary

 try {
        //get latest product data and latest stock from api
        $latestStocksInfo = Product::getLatestProductWithStockFromApi();
    } catch (\Exception $error) {
        try {
            $latestStocksInfo = Product::getLatestProductWithStockFromDb();
        } catch (\Exception $ex) {
            /*log exception */
            Log::channel('report')->error(['message'=>$ex->getMessage(),'file'=>$ex->getFile(),'line'=>$ex->getLine(),'Previous'=>$ex->getPrevious()]);///------------->>>>>>>> this problem when use 
            Log::channel('report')->error(['message'=>$ex->getMessage(),'file'=>$ex->getFile(),'line'=>$ex->getLine()]);///------------->>>>>>>> this code is ok 
        }
        Log::channel('report')->error(['message'=>$error->getMessage(),'file'=>$error->getFile(),'line'=>$error->getLine()]);

        /***log exception ***/
    }

Fastest way for Android Studio 3.x.x and Android Studio 4.x.x

1.Go to the design tab of the activity layout

2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation

Your problem is that you are naming your component class Date. When you call new Date() within your class, it won't create an instance of the Date you expect it to create (which is likely this Date)- it will try to create an instance of your component class. Then the constructor will try to create another instance, and another instance, and another instance... Until you run out of stack space and get the error you're seeing.

If you want to use Date within your class, try naming your class something different such as Calendar or DateComponent.

The reason for this is how JavaScript deals with name scope: Whenever you create a new named entity, if there is already an entity with that name in scope, that name will stop referring to the previous entity and start referring to your new entity. So if you use the name Date within a class named Date, the name Date will refer to that class and not to any object named Date which existed before the class definition started.

You can adjust the plot margins with plot.margin in theme() and then move your axis labels and title with the vjust argument of element_text(). For example :

library(ggplot2)
library(grid)
qplot(rnorm(100)) +
    ggtitle("Title") +
    theme(axis.title.x=element_text(vjust=-2)) +
    theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
    theme(plot.title=element_text(size=15, vjust=3)) +
    theme(plot.margin = unit(c(1,1,1,1), "cm"))

will give you something like this :

If you want more informations about the different theme() parameters and their arguments, you can just enter ?theme at the R prompt.

It seems to me that those people who never learned Lisp or Scheme as an undergraduate are now discovering it. As with a lot of things in this field there is a tendency to hype and create high expectations...

It will pass.

Functional programming is great. However, it will not take over the world. C, C++, Java, C#, etc will still be around.

What will come of this I think is more cross-language ability - for example implementing things in a functional language and then giving access to that stuff in other languages.

You should check out Softerra's LDAP Browser (the free version of LDAP Administrator), which can be downloaded here :

http://www.ldapbrowser.com/download.htm

I've used this application extensively for all my Active Directory, OpenLDAP, and Novell eDirectory development, and it has been absolutely invaluable.

If you just want to check and see if a username\password combination works, all you need to do is create a "Profile" for the LDAP server, and then enter the credentials during Step 3 of the creation process :

By clicking "Finish", you'll effectively issue a bind to the server using the credentials, auth mechanism, and password you've specified. You'll be prompted if the bind does not work.

This is so easy with jquery:

If below is your anchor link:

<a data-toggle="modal" data-id="@book.Id" title="Add this item" class="open-AddBookDialog"></a>

In the show event of your modal you can access to the anchor tag like below

//triggered when modal is shown
$('#modal_id').on('shown.bs.modal', function(event) {

    // The reference tag is your anchor tag here
    var reference_tag = $(event.relatedTarget); 
    var id = reference_tag.data('id')
    // ...
    // ...
})

When you use the input function it automatically turns it into a string. You need to go:

vote = int(input('Enter the name of the player you wish to vote for'))

which turns the input into a int type value

You can use EasyDict library ^(doc):

EasyDict allows to access dict values as attributes (works recursively). A Javascript-like properties dot notation for python dicts.

USEAGE

>>> from easydict import EasyDict as edict
>>> d = edict({'foo':3, 'bar':{'x':1, 'y':2}})
>>> d.foo
3
>>> d.bar.x
1

>>> d = edict(foo=3)
>>> d.foo
3

[INSTALLATION]:

• pip install easydict

Sometimes it cannot clear the DEBUG folder. What I did and worked was renaming the file that could not be deleted. So, erase all the folder and the file that cannot be deleted, rename to, for example, "_old".

"C:\Program Files\PuTTY\pscp.exe" -scp file.py server.com:

file.py will be uploaded into your HOME dir on remote server.

or when the remote server has a different user, use "C:\Program Files\PuTTY\pscp.exe" -l username -scp file.py server.com:

After connecting to the server pscp will ask for a password.

int diffInDays = (int)( (newerDate.getTime() - olderDate.getTime()) 
                 / (1000 * 60 * 60 * 24) )

Note that this works with UTC dates, so the difference may be a day off if you look at local dates. And getting it to work correctly with local dates requires a completely different approach due to daylight savings time.

Not really, no.

Java doesn't have pointers. If you really wanted you could try to emulate them by building around something like reflection, but it would have all of the complexity of pointers with none of the benefits.

Java doesn't have pointers because it doesn't need them. What kind of answers were you hoping for from this question, i.e. deep down did you hope you could use them for something or was this just curiousity?

The following takes any valid datetime value and returns the number of days in the associated month... it eliminates the ambiguity of both other answers...

 // pass in any date as parameter anyDateInMonth
function daysInMonth(anyDateInMonth) {
    return new Date(anyDateInMonth.getFullYear(), 
                    anyDateInMonth.getMonth()+1, 
                    0).getDate();}

There seems to be a lot of misinformation about how to use this event going around (even in upvoted answers on this page).

The onbeforeunload event API is supplied by the browser for a specific purpose: The only thing you can do that's worth doing in this method is to return a string which the browser will then prompt to the user to indicate to them that action should be taken before they navigate away from the page. You CANNOT prevent them from navigating away from a page (imagine what a nightmare that would be for the end user).

Because browsers use a confirm prompt to show the user the string you returned from your event listener, you can't do anything else in the method either (like perform an ajax request).

In an application I wrote, I want to prompt the user to let them know they have unsaved changes before they leave the page. The browser prompts them with the message and, after that, it's out of my hands, the user can choose to stay or leave, but you no longer have control of the application at that point.

An example of how I use it (pseudo code):

onbeforeunload = function() {

  if(Application.hasUnsavedChanges()) {
    return 'You have unsaved changes. Please save them before leaving this page';
  }


};

If (and only if) the application has unsaved changes, then the browser prompts the user to either ignore my message (and leave the page anyway) or to not leave the page. If they choose to leave the page anyway, too bad, there's nothing you can do (nor should be able to do) about it.

Empty dictionaries evaluate to False in Python:

>>> dct = {}
>>> bool(dct)
False
>>> not dct
True
>>>

Thus, your isEmpty function is unnecessary. All you need to do is:

def onMessage(self, socket, message):
    if not self.users:
        socket.send("Nobody is online, please use REGISTER command" \
                    " in order to register into the server")
    else:
        socket.send("ONLINE " + ' ' .join(self.users.keys()))

They showed up after installing Ankh SVN

I stumbled upon this question via a Google search for a very similar one (using the serial port on a server from a Linux client over TCP/IP), so, even though this is not an answer to exact original question, some of the code might be useful to the original poster, I think:

• Making a Linux box with a serial port listen on the TCP port to share the modem: ser2net
• Using this "shared" modem from another Linux workstation: remtty

Definitely in Modules.

• Sheets can be deleted, copied and moved with surprising results.
• You can't call code in sheet "code-behind" from other modules without fully qualifying the reference. This will lead to coupling of the sheet and the code in other modules/sheets.
• Modules can be exported and imported into other workbooks, and put under version control
• Code in split logically into modules (data access, utilities, spreadsheet formatting etc.) can be reused as units, and are easier to manage if your macros get large.

Since the tooling is so poor in primitive systems such as Excel VBA, best practices, obsessive code hygiene and religious following of conventions are important, especially if you're trying to do anything remotely complex with it.

This article explains the intended usages of different types of code containers. It doesn't qualify why these distinctions should be made, but I believe most developers trying to develop serious applications on the Excel platform follow them.

There's also a list of VBA coding conventions I've found helpful, although they're not directly related to Excel VBA. Please ignore the crazy naming conventions they have on that site, it's all crazy hungarian.

import csv

def read_cell(x, y):
    with open('file.csv', 'r') as f:
        reader = csv.reader(f)
        y_count = 0
        for n in reader:
            if y_count == y:
                cell = n[x]
                return cell
            y_count += 1

print (read_cell(4, 8)) 

This example prints cell 4, 8 in Python 3.

FWIW, I had exactly the same question, but I could not find the answer here. It's probably not portable, but at least for gitolite, I can run the following to get what I want:

$ ssh [email protected] info
hello akim, this is gitolite 2.3-1 (Debian) running on git 1.7.10.4
the gitolite config gives you the following access:
     R   W     android
     R   W     bistro
     R   W     checkpn
...

In a talk about core containers internals in Python at PyCon 2012, Raymond Hettinger is suggesting to use [None] * n to pre-allocate the length you want.

Slides available as PPT or via Google

The whole slide deck is quite interesting. The presentation is available on YouTube, but it doesn't add much to the slides.

Another way to encode the message you intend is to add another field to track "set" fields:

syntax="proto3";

package qtprotobuf.examples;

message SparseMessage {
    repeated uint32 fieldsUsed = 1;
    bool   attendedParty = 2;
    uint32 numberOfKids  = 3;
    string nickName      = 4;
}

message ExplicitMessage {
    enum PARTY_STATUS {ATTENDED=0; DIDNT_ATTEND=1; DIDNT_ASK=2;};
    PARTY_STATUS attendedParty = 1;
    bool   indicatedKids = 2;
    uint32 numberOfKids  = 3;
    enum NO_NICK_STATUS {HAS_NO_NICKNAME=0; WOULD_NOT_ADMIT_TO_HAVING_HAD_NICKNAME=1;};
    NO_NICK_STATUS noNickStatus = 4;
    string nickName      = 5;
}

This is especially appropriate if there is a large number of fields and only a small number of them have been assigned.

In python, usage would look like this:

import field_enum_example_pb2
m = field_enum_example_pb2.SparseMessage()
m.attendedParty = True
m.fieldsUsed.append(field_enum_example_pb2.SparseMessages.ATTENDEDPARTY_FIELD_NUMBER)

i personally use the jquery dump plugin alot to dump objects, its a bit similar to php's print_r() function Basic usage:

var obj = {
            hubba: "Some string...",
            bubba: 12.5,
            dubba: ["One", "Two", "Three"]
        }
$("#dump").append($.dump(obj));
/* will return:
Object { 
     hubba: "Some string..."
     bubba: 12.5
     dubba: Array ( 
          0 => "One"
          1 => "Two"
          2 => "Three"
     )
}
*/

Its very human readable, i also recommend this site http://json.parser.online.fr/ for creating/parsing/reading json, because it has nice colors

If you want two objects with the same elements but in a different order to compare equal, then the obvious thing to do is compare sorted copies of them - for instance, for the dictionaries represented by your JSON strings a and b:

import json

a = json.loads("""
{
    "errors": [
        {"error": "invalid", "field": "email"},
        {"error": "required", "field": "name"}
    ],
    "success": false
}
""")

b = json.loads("""
{
    "success": false,
    "errors": [
        {"error": "required", "field": "name"},
        {"error": "invalid", "field": "email"}
    ]
}
""")

>>> sorted(a.items()) == sorted(b.items())
False

... but that doesn't work, because in each case, the "errors" item of the top-level dict is a list with the same elements in a different order, and sorted() doesn't try to sort anything except the "top" level of an iterable.

To fix that, we can define an ordered function which will recursively sort any lists it finds (and convert dictionaries to lists of (key, value) pairs so that they're orderable):

def ordered(obj):
    if isinstance(obj, dict):
        return sorted((k, ordered(v)) for k, v in obj.items())
    if isinstance(obj, list):
        return sorted(ordered(x) for x in obj)
    else:
        return obj

If we apply this function to a and b, the results compare equal:

>>> ordered(a) == ordered(b)
True

inflater.inflate(R.layout.listheader, container, false);

being container the Fragment's ViewGroup, inflates the headerview with a LayoutParam that extends from FragmentLayout but ListView expect it to be a AbsListView.LayoutParams instead.

So, my problem was solved solved by inflating the header view passing the list as container:

ListView list = fragmentview.findViewById(R.id.listview);
View headerView = inflater.inflate(R.layout.listheader, list, false);

then

list.addHeaderView(headerView, null, false);

Kinda late answer but I hope this can help someone

Thanks guys for all the help, I really appreciate but I actually did some thinking and start doing some pseudo code and came up with this.

import java.util.Scanner;

public class Project {

public static void main(String[] args) {



//variable declaration  
Scanner scan = new Scanner(System.in);
final int MIN = 60, HRS = 3600, DYS = 84600;
int input, days, seconds, minutes, hours, rDays, rHours;

//input 
System.out.println("Enter amount of seconds!");
input = scan.nextInt();


//calculations
days = input/DYS;
rDays = input%DYS;
hours = rDays/HRS;
rHours = rDays%HRS;
minutes = rHours/MIN;
seconds = rHours%MIN;

//output
if (input >= DYS) {
    System.out.println(input + " seconds equals to " + days + " days " + hours + " hours " + minutes + " minutes " + seconds + " seconds");
}

else if (input >= HRS && input < DYS) {
    System.out.println(input + " seconds equals to " + hours + " hours " + minutes + " minutes " + seconds + " seconds");
}

else if (input >= MIN && input < HRS) {
    System.out.println(input + " seconds equals to " + minutes + " minutes " + seconds + " seconds");
}

else if (input < MIN) {
    System.out.println(input + " seconds equals to seconds");
}

scan.close();


}   

I know it looks really noobie but keep in mind I'm still new not just Java but programming entirely, and who knew pseudo code was actually really helpful.

Two ways to implement a Caesar Cipher:

Option 1: Change chars to ASCII numbers, then you can increase the value, then revert it back to the new character.

Option 2: Use a Map map each letter to a digit like this.

A - 0
B - 1
C - 2
etc...

With a map you don't have to re-calculate the shift every time. Then you can change to and from plaintext to encrypted by following map.

It has been my experience that ASP MVC really does not like traditional use of button so much. Instead I use:

  <input type="button" class="addYourCSSClassHere" value="WordsOnButton" onclick="window.location= '@Url.Action( "ActionInControllerHere", "ControllerNameHere")'" />

Taking

1. E is the starting point of the ray,
2. L is the end point of the ray,
3. C is the center of sphere you're testing against
4. r is the radius of that sphere

Compute:
d = L - E ( Direction vector of ray, from start to end )
f = E - C ( Vector from center sphere to ray start )

Then the intersection is found by..
Plugging:
P = E + t * d
This is a parametric equation:
P_x = E_x + td_x
P_y = E_y + td_y
into
(x - h)² + (y - k)² = r²
(h,k) = center of circle.

Note: We've simplified the problem to 2D here, the solution we get applies also in 3D

to get:

1. Expand x² - 2xh + h² + y² - 2yk + k² - r² = 0
2. Plug x = e_x + td_x
   y = e_y + td_y
   ( e_x + td_x )² - 2( e_x + td_x )h + h² + ( e_y + td_y )² - 2( e_y + td_y )k + k² - r² = 0
3. Explode e_x² + 2e_xtd_x + t²d_x² - 2e_xh - 2td_xh + h² + e_y² + 2e_ytd_y + t²d_y² - 2e_yk - 2td_yk + k² - r² = 0
4. Group t²( d_x² + d_y² ) + 2t( e_xd_x + e_yd_y - d_xh - d_yk ) + e_x² + e_y² - 2e_xh - 2e_yk + h² + k² - r² = 0
5. Finally, t²( d · d ) + 2t( e · d - d · c ) + e · e - 2( e · c ) + c · c - r² = 0
   Where d is the vector d and · is the dot product.
6. And then, t²( d · d ) + 2t( d · ( e - c ) ) + ( e - c ) · ( e - c ) - r² = 0
7. Letting f = e - c t²( d · d ) + 2t( d · f ) + f · f - r² = 0

So we get:
t² * (d · d) + 2t*( f · d ) + ( f · f - r² ) = 0

So solving the quadratic equation:

float a = d.Dot( d ) ;
float b = 2*f.Dot( d ) ;
float c = f.Dot( f ) - r*r ;

float discriminant = b*b-4*a*c;
if( discriminant < 0 )
{
  // no intersection
}
else
{
  // ray didn't totally miss sphere,
  // so there is a solution to
  // the equation.
  
  discriminant = sqrt( discriminant );

  // either solution may be on or off the ray so need to test both
  // t1 is always the smaller value, because BOTH discriminant and
  // a are nonnegative.
  float t1 = (-b - discriminant)/(2*a);
  float t2 = (-b + discriminant)/(2*a);

  // 3x HIT cases:
  //          -o->             --|-->  |            |  --|->
  // Impale(t1 hit,t2 hit), Poke(t1 hit,t2>1), ExitWound(t1<0, t2 hit), 

  // 3x MISS cases:
  //       ->  o                     o ->              | -> |
  // FallShort (t1>1,t2>1), Past (t1<0,t2<0), CompletelyInside(t1<0, t2>1)
  
  if( t1 >= 0 && t1 <= 1 )
  {
    // t1 is the intersection, and it's closer than t2
    // (since t1 uses -b - discriminant)
    // Impale, Poke
    return true ;
  }

  // here t1 didn't intersect so we are either started
  // inside the sphere or completely past it
  if( t2 >= 0 && t2 <= 1 )
  {
    // ExitWound
    return true ;
  }
  
  // no intn: FallShort, Past, CompletelyInside
  return false ;
}

add to your script in page :

$( window ).resize(function() {
    var table = $('#tableId').DataTable();
    $('#container').css( 'display', 'block' );
    table.columns.adjust().draw();
});

check out distributionUrl setting in gradle-wrapper.properties. I changed https to http, then my problem was solved.

Simply just add auto_increment Constraint In column or MODIFY COLUMN :-

 ALTER TABLE `emp` MODIFY COLUMN `id` INT NOT NULL UNIQUE AUTO_INCREMENT FIRST;

Or add a column first then change column as -

1. Alter TABLE `emp` ADD COLUMN `id`;

2. ALTER TABLE `emp` CHANGE COLUMN `id` `Emp_id` INT NOT NULL UNIQUE AUTO_INCREMENT FIRST;

I found a caveat that no one so far has mentioned. I don't know if it will come up often in practical situations, but here it is for the sake of completeness.

Usually, calculating a number modulo infinity returns itself as a float, but a fraction modulo infinity returns nan (not a number). Here is an example:

>>> from fractions import Fraction
>>> from math import inf
>>> 3 % inf
3.0
>>> 3.5 % inf
3.5
>>> Fraction('1/3') % inf
nan

I filed an issue on the Python bug tracker. It can be seen at https://bugs.python.org/issue32968.

Update: this will be fixed in Python 3.8.

Did you try ../../env_${env}.properties ?

Normally we do the following when module2 is on the same level as the sub-modules

<modules>
    <module>../sub-module1</module>
    <module>../sub-module2</module>
    <module>../sub-module3</module>
</modules>

I would think the ../.. would let you jump up two levels. If not, you might want to contact the plug in authors and see if this is a known issue.

git reflog show should show you the history of HEAD. You can use that to figure out where you were before the pull. Then you can reset your HEAD to that commit.

For .NET usage:

\p{L}{3,}

If you are trying to read fieldA from tableA and save it on fieldB on the same table, when fieldc = fieldd you might want consider this.

UPDATE tableA,
    tableA AS tableA_1 
SET 
    tableA.fieldB= tableA_1.filedA
WHERE
    (((tableA.conditionFild) = 'condition')
        AND ((tableA.fieldc) = tableA_1.fieldd));

Above code copies the value from fieldA to fieldB when condition-field met your condition. this also works in ADO (e.g access )

source: tried myself

Another option is to pass the single quote as an awk variable:

awk -v q=\' 'BEGIN {FS=" ";} {printf "%s%s%s ", q, $1, q}'

Simpler example with string concatenation:

# Prints 'test me', *including* the single quotes.
$ awk -v q=\' '{print q $0 q }' <<<'test me'
'test me'

You might find the Semantic Versioning Specification useful.

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

You could also use ld option -Bdynamic

gcc <objectfiles> -static -lstatic1 -lstatic2 -Wl,-Bdynamic -ldynamic1 -ldynamic2

All libraries after it (including system ones linked by gcc automatically) will be linked dynamically.

This technique allows you to change the text of the "back" button without affecting the title of any of the view controllers or seeing the back button text change during the animation.

Add this to the init method in the calling view controller:

UIBarButtonItem *temporaryBarButtonItem = [[UIBarButtonItem alloc] init];   
temporaryBarButtonItem.title = @"Back";
self.navigationItem.backBarButtonItem = temporaryBarButtonItem;
[temporaryBarButtonItem release];

All you need is to set values first to your RadioButton, for example:

RadioButton radioButton = (RadioButton)findViewById(R.id.radioButton);      
radioButton.setId(1);        //some int value

and then whenever this spacific radioButton will be chosen you can pull its value by the Id you gave it with

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radioGroup);                     
int whichIndex = radioGroup.getCheckedRadioButtonId(); //of course the radioButton
                                                       //should be inside the "radioGroup"
                                                       //in the XML

Cheers!

The modern way to do it that maintains the order is:

>>> from collections import OrderedDict
>>> list(OrderedDict.fromkeys(lseparatedOrbList))

as discussed by Raymond Hettinger (python core dev) in this answer. In python 3.5 and above this is also the fastest way - see the linked answer for details. However the keys must be hashable (as is the case in your list I think)

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

Simply use below method

private fun hideKeyboard(activity: Activity, editText: EditText) {
    editText.clearFocus()
    (activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).hideSoftInputFromWindow(editText.windowToken, 0)
}

An application can read 3 types of value from the application.properties file.

application.properties

     my.name=kelly

my.dbConnection ={connection_srting:'http://localhost:...',username:'benz',password:'pwd'}

class file

@Value("${my.name}")
private String name;

@Value("#{${my.dbConnection}}")
private Map<String,String> dbValues;

If you don't have a property in application.properties then you can use default value

        @Value("${your_name : default value}")
         private String msg; 

Convert to seconds those strings:

var str1 = '10:20:45';
var str2 = '5:10:10';

str1 =  str1.split(':');
str2 =  str2.split(':');

totalSeconds1 = parseInt(str1[0] * 3600 + str1[1] * 60 + str1[0]);
totalSeconds2 = parseInt(str2[0] * 3600 + str2[1] * 60 + str2[0]);

// compare them

if (totalSeconds1 > totalSeconds2 ) { // etc...

Try this:

preg_match("/net(.*)\.php$/","http://php.net/manual/en/function.preg-match.php", $matches);
echo $matches[1];
// prints /manual/en/function.preg-match

You want

String[] strarray = strlist.toArray(new String[0]);

See here for the documentation and note that you can also call this method in such a way that it populates the passed array, rather than just using it to work out what type to return. Also note that maybe when you print your array you'd prefer

System.out.println(Arrays.toString(strarray));

since that will print the actual elements.

MinGW would be a direct translation off gcc for windows, or you might want to check out LCC, vanilla c (more or less) with an IDE. Pelles C seems to be based off lcc and has a somewhat nicer IDE, though I haven't used it personally. Of course there is always the Express Edition of MSVC which is free, but that's your call.

That should work. Better if you pass a function to val:

$('#replyBox').val(function(i, text) {
    return text + quote;
});

This way you avoid searching the element and calling val twice.

You could use very easily reflection to list all properties, methods and values.

For Gecko based browsers you can use the .toSource() method:

var data = new Object();
data["firstname"] = "John";
data["lastname"] = "Smith";
data["age"] = 21;

alert(data.toSource()); //Will return "({firstname:"John", lastname:"Smith", age:21})"

But since you use Firebug, why not just use console.log?

Also make sure that the following property is set in your hibernate bean configuration:

<property name="packagesToScan" value="yourpackage" />

This tells spring and hibernate where to find your domain classes annotated as entities.

MSDN:

There is a very low probability that the value of the new Guid is all zeroes or equal to any other Guid.

After more than five years I answer my question. I think that the problem with a negative duration can be solved by a simple correction:

LocalDateTime fromDateTime = LocalDateTime.of(2014, 9, 9, 7, 46, 45);
LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 10, 6, 46, 45);

Period period = Period.between(fromDateTime.toLocalDate(), toDateTime.toLocalDate());
Duration duration = Duration.between(fromDateTime.toLocalTime(), toDateTime.toLocalTime());

if (duration.isNegative()) {
    period = period.minusDays(1);
    duration = duration.plusDays(1);
}
long seconds = duration.getSeconds();
long hours = seconds / SECONDS_PER_HOUR;
long minutes = ((seconds % SECONDS_PER_HOUR) / SECONDS_PER_MINUTE);
long secs = (seconds % SECONDS_PER_MINUTE);
long time[] = {hours, minutes, secs};
System.out.println(period.getYears() + " years "
            + period.getMonths() + " months "
            + period.getDays() + " days "
            + time[0] + " hours "
            + time[1] + " minutes "
            + time[2] + " seconds.");

Note: The site https://www.epochconverter.com/date-difference now correctly calculates the time difference.

Thank you all for your discussion and suggestions.

you can put in a table cell and then align the cell content.

<table>
   <tr>
     <td align="center">
        <input type="button" value="Some Button">
     </td>
   </tr>
</table>

I would do something like:

select
 A.id, A.age, B.count 
from 
 students A, 
 (select age, count(*) as count from students group by age) B
where A.age=B.age;

More generic approatch using JQuery library closest() and submit() buttons. Here you do not have to specify whitch form you want to submit, submits the form it is in.

<a href="#" onclick="$(this).closest('form').submit()">Submit Link</a>

Redirecting from HTTP to HTTPS with PHP on IIS

I was having trouble getting redirection to HTTPS to work on a Windows server which runs version 6 of MS Internet Information Services (IIS). I’m more used to working with Apache on a Linux host so I turned to the Internet for help and this was the highest ranking Stack Overflow question when I searched for “php redirect http to https”. However, the selected answer didn’t work for me.

After some trial and error, I discovered that with IIS, $_SERVER['HTTPS'] is set to off for non-TLS connections. I thought the following code should help any other IIS users who come to this question via search engine.

<?php
if (! isset($_SERVER['HTTPS']) or $_SERVER['HTTPS'] == 'off' ) {
    $redirect_url = "https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header("Location: $redirect_url");
    exit();
}
?>

Edit: From another Stack Overflow answer, a simpler solution is to check if($_SERVER["HTTPS"] != "on").

public static JsonSerializerSettings JsonSerializer { get; set; } = new JsonSerializerSettings()

            NullValueHandling = NullValueHandling.Ignore,
            ContractResolver = new LowercaseContractResolver()
        };

Hello,

I'm using this property when I need set JsonSerializerSettings

From https://developer.apple.com/library/prerelease/ios/documentation/swift/conceptual/swift_programming_language/CollectionTypes.html:

If you need to use a dictionary’s keys or values with an API that takes an Array instance, initialize a new array with the keys or values property:

let airportCodes = [String](airports.keys) // airportCodes is ["TYO", "LHR"]   
let airportNames = [String](airports.values) // airportNames is ["Tokyo", "London Heathrow"]

Just discovered that if the source table for a subform is updated using adodb, it takes a while until the requery can find the updated information.

In my case, I was adding some records with 'dbconn.execute "sql" ' and wondered why the requery command in vba doesn't seem to work. When I was debugging, the requery worked. Added a 2-3 second wait in the code before requery just to test made a difference.

But changing to 'currentdb.execute "sql" ' fixed the problem immediately.

You're probably thinking of the java.util.ArrayList, not the array.

IF (OBJECT_ID('DF_Constraint') IS NOT NULL)
BEGIN
    ALTER TABLE [dbo].[tableName]
    DROP CONSTRAINT DF_Constraint
END

This should be enough to get you started.

class Program
{        
    static void Main(String[] args)
    {
        const int bufferSize = 1024;

        var sb = new StringBuilder();
        var buffer = new Char[bufferSize];
        var length = 0L;
        var totalRead = 0L;
        var count = bufferSize; 

        using (var sr = new StreamReader(@"C:\Temp\file.txt"))
        {
            length = sr.BaseStream.Length;               
            while (count > 0)
            {                    
                count = sr.Read(buffer, 0, bufferSize);
                sb.Append(buffer, 0, count);
                totalRead += count;
            }                
        }

        Console.ReadKey();
    }
}

Another option is to use multer, which uses busboy under the hood, but is simpler to set up.

var multer = require('multer');

Use multer and set the destination for the upload:

app.use(multer({dest:'./uploads/'}));

Create a form in your view, enctype='multipart/form-data is required for multer to work:

form(role="form", action="/", method="post", enctype="multipart/form-data")
    div(class="form-group")
        label Upload File
        input(type="file", name="myfile", id="myfile")

Then in your POST you can access the data about the file:

app.post('/', function(req, res) {
  console.dir(req.files);
});

JSONObject site = (JSONObject)jsonSites.get(i); // Exception happens here.

The return type of jsonSites.get(i) is JSONArray not JSONObject. Because sites have two '[', two means there are two arrays here.

The example below is based on the html5rocks solution. It uses the browser's FileReader() function. Newer browsers only.

See http://www.html5rocks.com/en/tutorials/file/dndfiles/#toc-reading-files

In this example, the user selects an HTML file. It uploaded into the <textarea>.

<form enctype="multipart/form-data">
<input id="upload" type=file   accept="text/html" name="files[]" size=30>
</form>

<textarea class="form-control" rows=35 cols=120 id="ms_word_filtered_html"></textarea>

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

    // use the 1st file from the list
    f = files[0];

    var reader = new FileReader();

    // Closure to capture the file information.
    reader.onload = (function(theFile) {
        return function(e) {

          jQuery( '#ms_word_filtered_html' ).val( e.target.result );
        };
      })(f);

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

  document.getElementById('upload').addEventListener('change', handleFileSelect, false);
</script>

For Tomcat 8, I had to add the following line to catalina.properties for preventing jars scanned by Tomcat:

Below is the code I used to replace some text, with colored text. It's simple, took the text and replace it within an HTML tag. It works for each words in that class tags.

$('.hightlight').each(function(){
    //highlight_words('going', this);
    var high = 'going';
    high = high.replace(/\W/g, '');
    var str = high.split(" ");
    var text = $(this).text();
    text = text.replace(str, "<span style='color: blue'>"+str+"</span>");
    $(this).html(text);
});

Although returning a pointer to a local object is bad practice, it didn't cause the kaboom here. Here's why you got a segfault:

int *fun()
{
    int *point;
    *point=12;  <<<<<<  your program crashed here.
    return point;
}

The local pointer goes out of scope, but the real issue is dereferencing a pointer that was never initialized. What is the value of point? Who knows. If the value did not map to a valid memory location, you will get a SEGFAULT. If by luck it mapped to something valid, then you just corrupted memory by overwriting that place with your assignment to 12.

Since the pointer returned was immediately used, in this case you could get away with returning a local pointer. However, it is bad practice because if that pointer was reused after another function call reused that memory in the stack, the behavior of the program would be undefined.

int *fun()
{
    int point;
    point = 12;
    return (&point);
}

or almost identically:

int *fun()
{
    int point;
    int *point_ptr;
    point_ptr = &point;
    *point_ptr = 12;
    return (point_ptr);
}

Another bad practice but safer method would be to declare the integer value as a static variable, and it would then not be on the stack and would be safe from being used by another function:

int *fun()
{
    static int point;
    int *point_ptr;
    point_ptr = &point;
    *point_ptr = 12;
    return (point_ptr);
}

or

int *fun()
{
    static int point;
    point = 12;
    return (&point);
}

As others have mentioned, the "right" way to do this would be to allocate memory on the heap, via malloc.

You normally use a tool like pip to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.

For this to work, you do need to install the wheel package:

pip install wheel

You can then tell pip to install the project (and it'll download the wheel if available), or the wheel file directly:

pip install project_name  # discover, download and install
pip install wheel_file.whl  # directly install the wheel

The wheel module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:

python -m wheel install wheel_file.whl

Also see the wheel project documentation.

SELECT (to_date('02-JAN-2013') - to_date('02-JAN-2012')) days_between

You shouldn't put a ListView inside a ScrollView because the ListView class implements its own scrolling and it just doesn't receive gestures because they all are handled by the parent ScrollView

#include <iostrema>

int main(){
    int32_t maxSigned = -1U >> 1;
    cout << maxSigned << '\n';
    return 0;
}

It might be architecture dependent but it does work at least in my setup.

You can set this at boot by adding the "elevator" parameter to the kernel cmdline (such as in grub.cfg)

Example:

elevator=deadline

This will make "deadline" the default I/O scheduler for all block devices.

If you'd like to query or change the scheduler after the system has booted, or would like to use a different scheduler for a specific block device, I recommend installing and use the tool ioschedset to make this easy.

https://github.com/kata198/ioschedset

If you're on Archlinux it's available in aur:

https://aur.archlinux.org/packages/ioschedset

Some example usage:

# Get i/o scheduler for all block devices
[username@hostname ~]$ io-get-sched
sda:    bfq
sr0:    bfq

# Query available I/O schedulers
[username@hostname ~]$ io-set-sched --list
mq-deadline kyber bfq none

# Set sda to use "kyber"
[username@hostname ~]$ io-set-sched kyber /dev/sda
Must be root to set IO Scheduler. Rerunning under sudo...

[sudo] password for username:
+ Successfully set sda to 'kyber'!

# Get i/o scheduler for all block devices to assert change
[username@hostname ~]$ io-get-sched
sda:    kyber
sr0:    bfq

# Set all block devices to use 'deadline' i/o scheduler
[username@hostname ~]$ io-set-sched deadline
Must be root to set IO Scheduler. Rerunning under sudo...

+ Successfully set sda to 'deadline'!
+ Successfully set sr0 to 'deadline'!

# Get the current block scheduler just for sda
[username@hostname ~]$ io-get-sched sda
sda:    mq-deadline

Usage should be self-explanatory. The tools are standalone and only require bash.

Hope this helps!

EDIT: Disclaimer, these are scripts I wrote.

I fixed this issue by moving the project to the outer directory, and it then compiled successfully.

It was due to the long path of the project directory.

For example, I moved the project from:

D:/Android/Apps/AndroidStudioProject/AppName

to

D:/Android/AppName

In addition, strip has some variations:

Remove spaces in the BEGINNING and END of a string:

sentence= sentence.strip()

Remove spaces in the BEGINNING of a string:

sentence = sentence.lstrip()

Remove spaces in the END of a string:

sentence= sentence.rstrip()

All three string functions strip lstrip, and rstrip can take parameters of the string to strip, with the default being all white space. This can be helpful when you are working with something particular, for example, you could remove only spaces but not newlines:

" 1. Step 1\n".strip(" ")

Or you could remove extra commas when reading in a string list:

"1,2,3,".strip(",")

I know I might get criticized for suggesting dynamic SQL, but sometimes it's a good solution. Just make sure you understand the security implications before you consider this.

DECLARE @add_a_b_func nvarchar(4000) = N'SELECT @c = @a + @b;';
DECLARE @add_a_b_parm nvarchar(500) = N'@a int, @b int, @c int OUTPUT';

DECLARE @result int;
EXEC sp_executesql @add_a_b_func, @add_a_b_parm, 2, 3, @c = @result OUTPUT;
PRINT CONVERT(varchar, @result); -- prints '5'

Try this:

LocalDate initial = LocalDate.of(2014, 2, 13);
LocalDate start = initial.withDayOfMonth(1);         
LocalDate end = initial.withDayOfMonth(initial.getMonthOfYear().getLastDayOfMonth(false));
System.out.println(start);
System.out.println(end);

you can find the desire output but need to take care of parameter true/false for getLastDayOfMonth method

that parameter denotes leap year

# This is a regex solution.
import re
def removeHtml(html):
  if not html: return html
  # Remove comments first
  innerText = re.compile('<!--[\s\S]*?-->').sub('',html)
  while innerText.find('>')>=0: # Loop through nested Tags
    text = re.compile('<[^<>]+?>').sub('',innerText)
    if text == innerText:
      break
    innerText = text

  return innerText.strip()

Following the steps on https://code.visualstudio.com/docs/customization/colorizer#_common-questions worked well for me:

To extend an existing colorizer, you would create a simple package.json in a new folder under .vscode/extensions and provide the extensionDependencies attribute specifying the customization you want to add to. In the example below, an extension .mmd is added to the markdown colorizer. Note that not only must the extensionDependency name match the customization but also the language id must match the language id of the colorizer you are extending.

{
    "name": "MyMarkdown",
    "version": "0.0.1",
    "engines": {
        "vscode": "0.10.x"
    },
    "publisher": "none",
    "extensionDependencies": [
        "markdown"
    ],
    "contributes": {
        "languages": [{
            "id": "markdown",
            "aliases": ["mmd"],
            "extensions": [".mmd"]
        }]
    }
}

I have been implementing installation without user consent recently - it was a kiosk application for API level 21+ where I had full control over environment.

The basic requirements are

• API level 21+
• root access to install the updater as a system privileged app.

The following method reads and installs APK from InputStream:

public static boolean installPackage(Context context, InputStream in, String packageName)
            throws IOException {
        PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller();
        PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
                PackageInstaller.SessionParams.MODE_FULL_INSTALL);
        params.setAppPackageName(packageName);
        // set params
        int sessionId = packageInstaller.createSession(params);
        PackageInstaller.Session session = packageInstaller.openSession(sessionId);
        OutputStream out = session.openWrite("COSU", 0, -1);
        byte[] buffer = new byte[65536];
        int c;
        while ((c = in.read(buffer)) != -1) {
            out.write(buffer, 0, c);
        }
        session.fsync(out);
        in.close();
        out.close();

        Intent intent = new Intent(context, MainActivity.class);
        intent.putExtra("info", "somedata");  // for extra data if needed..

        Random generator = new Random();

        PendingIntent i = PendingIntent.getActivity(context, generator.nextInt(), intent,PendingIntent.FLAG_UPDATE_CURRENT);
            session.commit(i.getIntentSender());


        return true;
    }

The following code calls the installation

 try {
     InputStream is = getResources().openRawResource(R.raw.someapk_source);
                    installPackage(MainActivity.this, is, "com.example.apk");
     } catch (IOException e) {
                    Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
     }

for the whole thing to work you desperately need INSTALL_PACKAGES permission, or the code above will fail silently

<uses-permission
        android:name="android.permission.INSTALL_PACKAGES" />

to get this permission you must install your APK as System application which REQUIRES root (however AFTER you have installed your updater application it seem to work WITHOUT root)

To install as system application I created a signed APK and pushed it with

adb push updater.apk /sdcard/updater.apk

and then moved it to system/priv-app - which requires remounting FS (this is why the root is required)

adb shell
su
mount -o rw,remount /system
mv /sdcard/updater.apk /system/priv-app
chmod 644 /system/priv-app/updater.apk

for some reason it didn't work with simple debug version, but logcat shows useful info if your application in priv-app is not picked up for some reason.

I forgot that I had already an unused labs branch. Deleting it solved my problem:

git branch -d labs
git checkout -b labs/feature

Explanation:

Each name can only be a parent branch or a normal branch, not both. Thats why the branches labs and labs/feature can't exists both at the same time.

The reason: Branches are stored in the file system and there you also can't have a file labs and a directory labs at the same level.

maybe you forgot to add ";" after this line of code:

`quantity` INT NOT NULL)

To go directly to that folder, you can use the Set-Location cmdlet or cd alias:

Set-Location "Q:\My Test Folder"

Here's my solution:

String s = Integer.toBinaryString(5); //Convert decimal to binary
int p = 8; //preferred length
for(int g=0,j=s.length();g<p-j;g++, s= "0" + s);
System.out.println(s);

Output: 00000101

create a textbox:

 <TextBox Name="tb">
 ..hello..
</TextBox>

focus() ---> it is used to set input focus to the textbox control

tb.focus()

Try CLPP library. It's simple and flexible library for command line parameters parsing. Header-only and cross-platform. Uses ISO C++ and Boost C++ libraries only. IMHO it is easier than Boost.Program_options.

Library: http://sourceforge.net/projects/clp-parser

26 October 2010 - new release 2.0rc. Many bugs fixed, full refactoring of the source code, documentation, examples and comments have been corrected.

If you like Guava, you may use its Ints class:

For int ? byte[], use toByteArray():

byte[] byteArray = Ints.toByteArray(0xAABBCCDD);

Result is {0xAA, 0xBB, 0xCC, 0xDD}.

Its reverse is fromByteArray() or fromBytes():

int intValue = Ints.fromByteArray(new byte[]{(byte) 0xAA, (byte) 0xBB, (byte) 0xCC, (byte) 0xDD});
int intValue = Ints.fromBytes((byte) 0xAA, (byte) 0xBB, (byte) 0xCC, (byte) 0xDD);

Result is 0xAABBCCDD.

If your code says "int newVal=42" then you would reasonably expect that newVal is never uninitialised. But if you goto over this statement (which is what you're doing) then that's exactly what happens - newVal is in-scope but has not been assigned.

If that is what you really meant to happen then the language requires to make it explicit by saying "int newVal; newVal = 42;". Otherwise you can limit the scope of newVal to the single case, which is more likely what you wanted.

It may clarify things if you consider the same example but with "const int newVal = 42;"

if you're using bootstrap 3 set data-interval="false" on the HTML structure of carousel

example:

<div id="carousel-example-generic" class="carousel slide" data-ride="carousel" data-interval="false">

Peachpie

http://www.peachpie.io

https://github.com/iolevel/peachpie

Peachpie is PHP 7 compiler based on Roslyn by Microsoft and drawing from popular Phalanger. It allows PHP to be executed within the .NET/.NETCore by compiling the PHP code to pure MSIL.

Phalanger

http://v4.php-compiler.net/

http://wiki.php-compiler.net/Phalanger_Wiki

https://github.com/devsense/phalanger

Phalanger is a project which was started at Charles University in Prague and was supported by Microsoft. It compiles source code written in the PHP scripting language into CIL (Common Intermediate Language) byte-code. It handles the beginning of a compiling process which is completed by the JIT compiler component of the .NET Framework. It does not address native code generation nor optimization. Its purpose is to compile PHP scripts into .NET assemblies, logical units containing CIL code and meta-data.

Bambalam

https://github.com/xZero707/Bamcompile/

Bambalam PHP EXE Compiler/Embedder is a free command line tool to convert PHP applications to standalone Windows .exe applications. The exe files produced are totally standalone, no need for php dlls etc. The php code is encoded using the Turck MMCache Encode library so it's a perfect solution if you want to distribute your application while protecting your source code. The converter is also suitable for producing .exe files for windowed PHP applications (created using for example the WinBinder library). It's also good for making stand-alone PHP Socket servers/clients (using the php_sockets.dll extension). It's NOT really a compiler in the sense that it doesn't produce native machine code from PHP sources, but it works!

ZZEE PHPExe

http://www.zzee.com/phpexe/

ZZEE PHPExe compiles PHP, HTML, Javascript, Flash and other web files into Windows GUI exes. You can rapidly develop Windows GUI applications by employing the familiar PHP web paradigm. You can use the same code for online and Windows applications with little or no modification. It is a Commercial product.

phc-win

http://wiki.swiftlytilting.com/Phc-win

The PHP extension bcompiler is used to compile PHP script code into PHP bytecode. This bytecode can be included just like any php file as long as the bcompiler extension is loaded. Once all the bytecode files have been created, a modified Embeder is used to pack all of the project files into the program exe.

Requires

• php5ts.dll
• php_win32std.dll
• php_bcompiler.dll
• php-embed.ini

ExeOutput

http://www.exeoutput.com/

Commercial

WinBinder

http://winbinder.org/

WinBinder is an open source extension to PHP, the script programming language. It allows PHP programmers to easily build native Windows applications, producing quick and rewarding results with minimum effort. Even short scripts with a few dozen lines can generate a useful program, thanks to the power and flexibility of PHP.

PHPDesktop

https://github.com/cztomczak/phpdesktop

PHP Desktop is an open source project founded by Czarek Tomczak in 2012 to provide a way for developing native desktop applications using web technologies such as PHP, HTML5, JavaScript & SQLite. This project is more than just a PHP to EXE compiler, it embeds a web-browser (Internet Explorer or Chrome embedded), a Mongoose web-server and a PHP interpreter. The development workflow you are used to remains the same, the step of turning an existing website into a desktop application is basically a matter of copying it to "www/" directory. Using SQLite database is optional, you could embed mysql/postgresql database in application's installer.

PHP Nightrain

https://github.com/kjellberg/nightrain

Using PHP Nightrain you will be able to deploy and run HTML, CSS, JavaScript and PHP web applications as a native desktop application on Windows, Mac and the Linux operating systems. Popular PHP Frameworks (e.g. CakePHP, Laravel, Drupal, etc…) are well supported!

phc-win "fork"

https://github.com/RDashINC/phc-win

A more-or-less forked version of phc-win, it uses the same techniques as phc-win but supports almost all modern PHP versions. (5.3, 5.4, 5.5, 5.6, etc) It also can use Enigma VB to combine the php5ts.dll with your exe, aswell as UPX compress it. Lastly, it has win32std and winbinder compilied statically into PHP.

EDIT

Another option is to use

http://www.appcelerator.com/products/titanium-cross-platform-application-development/

an online compiler that can build executables for a number of different platforms, from a number of different languages including PHP

TideSDK

http://www.tidesdk.org/

TideSDK is actually the renamed Titanium Desktop project. Titanium remained focused on mobile, and abandoned the desktop version, which was taken over by some people who have open sourced it and dubbed it TideSDK.

Generally, TideSDK uses HTML, CSS and JS to render applications, but it supports scripted languages like PHP, as a plug-in module, as well as other scripting languages like Python and Ruby.

I found out today the keypress event is not fired when hitting the Enter key, so you might want to switch to keydown() or keyup() instead.

My test script:

        $('.module input').keydown(function (e) {
            var keyCode = e.which;
            console.log("keydown ("+keyCode+")")
            if (keyCode == 13) {
                console.log("enter");
                return false;
            }
        });
        $('.module input').keyup(function (e) {
            var keyCode = e.which;
            console.log("keyup ("+keyCode+")")
            if (keyCode == 13) {
                console.log("enter");
                return false;
            }
        });
        $('.module input').keypress(function (e) {
            var keyCode = e.which;
            console.log("keypress ("+keyCode+")");
            if (keyCode == 13) {
                console.log("Enter");
                return false;
            }
        });

The output in the console when typing "A Enter B" on the keyboard:

keydown (65)
keypress (97)
keyup (65)

keydown (13)
enter
keyup (13)
enter

keydown (66)
keypress (98)
keyup (66)

You see in the second sequence the 'keypress' is missing, but keydown and keyup register code '13' as being pressed/released. As per jQuery documentation on the function keypress():

Note: as the keypress event isn't covered by any official specification, the actual behavior encountered when using it may differ across browsers, browser versions, and platforms.

Tested on IE11 and FF61 on Server 2012 R2

it is just a sample to avoid max recursion error. we have to use option (maxrecursion 365); or option (maxrecursion 0);

DECLARE @STARTDATE datetime; 
DECLARE @EntDt datetime; 
set @STARTDATE = '01/01/2009';  
set @EntDt = '12/31/2009'; 
declare @dcnt int; 
;with DateList as   
 (   
    select @STARTDATE DateValue   
    union all   
    select DateValue + 1 from    DateList      
    where   DateValue + 1 < convert(VARCHAR(15),@EntDt,101)   
 )   
  select count(*) as DayCnt from (   
  select DateValue,DATENAME(WEEKDAY, DateValue ) as WEEKDAY from DateList
  where DATENAME(WEEKDAY, DateValue ) not IN ( 'Saturday','Sunday' )     
  )a
option (maxrecursion 365);

Check it's value property:

In jQuery (since your tag mentions it):

$('#fileInput').val()

Or in vanilla JavaScript:

document.getElementById('myFileInput').value

In my situation, I needed to retain unique keys with the array values, so I just used a second array:

$arr1 = array("alpha"=>"bravo","charlie"=>"delta","echo"=>"foxtrot");
unset($arr1);

$arr2 = array();
foreach($arr1 as $key=>$value) $arr2[$key] = $value;
$arr1 = $arr2
unset($arr2);

The rvest along with xml2 is another popular package for parsing html web pages.

library(rvest)
theurl <- "http://en.wikipedia.org/wiki/Brazil_national_football_team"
file<-read_html(theurl)
tables<-html_nodes(file, "table")
table1 <- html_table(tables[4], fill = TRUE)

The syntax is easier to use than the xml package and for most web pages the package provides all of the options ones needs.

You can write yourself a little console app and use System.Environment.Version to find out the version. Scott Hanselman gives a blog post about it.

Or look in the registry for the installed versions. HKLM\Software\Microsoft\NETFramework Setup\NDP

This seems to work as well

SELECT *
FROM makerar m1
WHERE m1.avg = (SELECT MAX(avg)
                FROM makerar m2
                WHERE m1.cname = m2.cname
               )

You can use this code:

<Button
android:id="@+id/img_sublist_carat"
android:layout_width="70dp"
android:layout_height="68dp"
android:layout_centerVertical="true"
android:layout_marginLeft="625dp"
android:contentDescription=""
android:background="@drawable/img_sublist_carat_selector"
android:visibility="visible" />

(Selector File) img_sublist_carat_selector.xml:

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_focused="true" 
       android:state_pressed="true"        
       android:drawable="@drawable/img_sublist_carat_highlight" />
 <item android:state_pressed="true" 
       android:drawable="@drawable/img_sublist_carat_highlight" />
 <item android:drawable="@drawable/img_sublist_carat_normal" />
</selector>

In order to use Windows Authentication one of two things needs to be true:

1. You are executing from the same machine as the database server.
2. You have an Active Directory environment and the user the application is executing under (usually the logged in user) has rights to connect to that database.

If neither of those are true you have to do one of two things:

1. Establish a Windows Domain Controller, connect all of the relevant machines to that controller, then fix SQL server to use domain accounts; OR,
2. Change SQL server to use both Windows and SQL Server accounts.

By FAR the easiest way is to change SQL Server to use both Windows and SQL server accounts. Then you just need to create a sql server user on the DB server and change your connection string to do that.

Best case option 1 will take a full day of installation and configuration. Option 2 ought to take about 5 minutes.

I found xunit-viewer, which has deprecated junit-viewer mentioned by @daniel-kristof-kiss.

It is very simple, automatically recursively collects all relevant files in ANT Junit XML format and creates a single html-file with filtering and other sweet features.

I use it to upload test results from Travis builds as Travis has no other support for collecting standard formatted test results output.

I think that you can use

$file= public_path(). "/download/info.pdf";

$headers = array(
        'Content-Type: ' . mime_content_type( $file ),
    );

With this you be sure that is a pdf.

As of Maven Eclipse (m2e) version 0.12 all Maven life-cycle goals must map to an installed m2e extension. In this case, the maven-ear-plugin had an-unmapped goal default-generate-application-xml.

You can exclude un-mapped life-cycle goals by simply following the instructions here:

https://wiki.eclipse.org/M2E_plugin_execution_not_covered

Alternatively, simply right-click on the error message in Eclipse and choosing Quick Fix -> Ignore for every pom with such errors.

You should be careful when ignoring life-cycle goals: typically goals do something useful and if you configure them to be ignored in Eclipse you may miss important build steps. You might also want to consider adding support to the Maven Eclipse EAR extension for the unmapped life-cycle goal.

You should find it in :

C:\Users\User Name\AppData\Local\Android\sdk\platform-tools

Add that to path, or change directory to there. The command sqlite3 is also there.

In the terminal you can type commands like

adb logcat //for logs
adb shell // for android shell

If you have only one char and not a string, you can use:

'\n'.charCodeAt();

omitting the 0...

It used to be significantly slower than 'n'.charCodeAt(0), but I've tested it now and I do not see any difference anymore (executed 10 billions times with and without the 0). Tested for performance only in Chrome and Firefox.

Update 2019 - Bootstrap 4

Since Bootstrap 3 used floats, it required clearfix resets every n (3 or 4) columns (.col-*) in the .row to prevent uneven wrapping of columns.

Now that Bootstrap 4 uses flexbox, there is no longer a need to wrap columns in separate .row tags, or to insert extra divs to force cols to wrap every n columns.

You can simply repeat all of the columns in a single .row container.

For example 3 columns in each visual row is:

<div class="row">
     <div class="col-4">...</div>
     <div class="col-4">...</div>
     <div class="col-4">...</div>
     <div class="col-4">...</div>
     <div class="col-4">...</div>
     <div class="col-4">...</div>
     <div class="col-4">...</div>
     (...repeat for number of items)
</div>

So for Bootstrap the ng-repeat is simply:

  <div class="row">
      <div class="col-4" ng-repeat="item in items">
          ... {{ item }}
      </div>
  </div>

One reason to always include a character set specification on every page containing text is to avoid cross site scripting vulnerabilities. In most cases the UTF-8 character set is the best choice for text, including HTML pages.

Open cmd and type the command below.

netstat -o -n -a | findstr 0.0:80

Last column of each row is the process identifier (PID)

You can find the application that reserves port 80, using taskmanager services tab or just type tasklist in cmd.

Then follow this link: http://www.ttkalec.com/blog/resolving-yellow-wamp-server-status-freeing-up-port-80-for-apache/

There are a couple of ways to do it.

1. To run the Docker overriding the USER setting

    docker exec -u 0 -it containerName bash
   

or

docker exec -u root -it --workdir / <containerName> bash

2. Make necessary file permissions, etc., during the image build in the Docker file

3. If all the packages are available in your Linux image, chpasswdin the dockerfile before the USER utility.

in Javascript

var id=document.getElementById("image");

id.src=base64Url;

Go to the preview version of tomcat e.g. : tomcat 8.3 and copy catalina.jar file and paste into the existing tomcat which you have facing the issue

A simple string replace will do the job. Take a look at the example program below:

using System;

namespace NewLineThingy
{
    class Program
    {
        static void Main(string[] args)
        {
            string str = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
            str = str.Replace("@", "@" + Environment.NewLine);
            Console.WriteLine(str);
            Console.ReadKey();
        }
    }
}

Using simple html,

 <div> 
    <object type="text/html" data="http://validator.w3.org/" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">
    </object>
 </div>

Or jquery,

<script>
        $("#mydiv")
            .html('<object data="http://your-website-domain"/>');
</script>

Adding to Cheeken's answer, This is how you sort a list of tuples by the 2nd item in descending order.

sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)],key=lambda x: x[1], reverse=True)

Looks like you use %p: Print Pointers

in python intended block mean there is every thing must be written in manner in my case I written it this way

 def btnClick(numbers):
 global operator
 operator = operator + str(numbers)
 text_input.set(operator)

Note.its give me error,until I written it in this way such that "giving spaces " then its giving me a block as I am trying to show you in function below code

def btnClick(numbers):
___________________________
|global operator
|operator = operator + str(numbers)
|text_input.set(operator)

Most common way:

console.log(object);

However I must mention JSON.stringify which is useful to dump variables in non-browser scripts:

console.log( JSON.stringify(object) );

The JSON.stringify function also supports built-in prettification as pointed out by Simon Zyx.

Example:

var obj = {x: 1, y: 2, z: 3};

console.log( JSON.stringify(obj, null, 2) ); // spacing level = 2

The above snippet will print:

{
  "x": 1,
  "y": 2,
  "z": 3
}

On caniuse.com you can view the browsers that support natively the JSON.stringify function: http://caniuse.com/json

You can also use the Douglas Crockford library to add JSON.stringify support on old browsers: https://github.com/douglascrockford/JSON-js

Docs for JSON.stringify: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

I hope this helps :-)

A solution working with map built-in fonction !

arg_names = ['command' ,'operation', 'parameter']
args = map(None, arg_names, sys.argv)
args = {k:v for (k,v) in args}

Then you just have to call your parameters like this:

if args['operation'] == "division":
    if not args['parameter']:
        ...
    if args['parameter'] == "euclidian":
        ...

I was told to do document.close after document.write, I dont see how or why but this caused my script to wait until I closed the print dialog before it ran my window.close.

var printContent = document.getElementbyId('wrapper').innerHTML;
var disp_setting="toolbar=no,location=no,directories=no,menubar=no, scrollbars=no,width=600, height=825, left=100, top=25"
var printWindow = window.open("","",disp_setting);
printWindow.document.write(printContent);
printWindow.document.close();
printWindow.focus();
printWindow.print();

printWindow.close();

This should work. You need to put in two slashes

str = str.replaceAll("(\\r\\n|\\n)", "<br />");

In this Reference, there is an example which shows

private final String REGEX = "\\d"; // a single digit

I have used two slashes in many of my projects and it seems to work fine!

With an iterator you can handle always the element which comes to order, not a specified index. So, you should not be troubled with the above matter.

Iterator itr = list.iterator();
String strElement = "";
while(itr.hasNext()){

  strElement = (String)itr.next();
  if(strElement.equals("2"))
  {
    itr.remove();
  }

I would use the padding attribute. This will allow you add a set number of pixels to either side of the element without the element loosing its span qualities:

• It won't become a block
• It will float as you expect

This method will only add to the padding however, so if you change the length of the content (from Categories to Tags, for example) the size of the content will change and the overall size of the element will change as well. But if you really want to set a rigid size, you should do as mentioned above and use a div.

See the box model for more details about the box model, content, padding, margin, etc.

I had a same issue on ubuntu 14.04 Here is a solution

sudo service docker start

or you can list images

docker images

df = df.loc[:, ~df.columns.str.contains('^Unnamed')]

In [162]: df
Out[162]:
   colA  ColB  colC  colD  colE  colF  colG
0    44    45    26    26    40    26    46
1    47    16    38    47    48    22    37
2    19    28    36    18    40    18    46
3    50    14    12    33    12    44    23
4    39    47    16    42    33    48    38

if the first column in the CSV file has index values, then you can do this instead:

df = pd.read_csv('data.csv', index_col=0)

Yes, ( ) captures a group. You can use it again with $i where i is the i'th capture group.

So:

search: (\w+\.someMethod\(\))

replace: ((TypeName)$1)

Hint: Ctrl + Space in the textboxes gives you all kinds of suggestions for regular expression writing.

In my case I have declared a Bool like this:

var isActivityOpen: Bool 

i.e. I declared it without unwrapping so, This is how I solved the (no initializer) error :

var isActivityOpen: Bool!

A way via extension function on IEnumerable that returns both the object and the minimum found. It takes a Func that can do any operation on the object in the collection:

public static (double min, T obj) tMin<T>(this IEnumerable<T> ienum, 
            Func<T, double> aFunc)
        {
            var okNull = default(T);
            if (okNull != null)
                throw new ApplicationException("object passed to Min not nullable");

            (double aMin, T okObj) best = (double.MaxValue, okNull);
            foreach (T obj in ienum)
            {
                double q = aFunc(obj);
                if (q < best.aMin)
                    best = (q, obj);
            }
            return (best);
        }

Example where object is an Airport and we want to find closest Airport to a given (latitude, longitude). Airport has a dist(lat, lon) function.

(double okDist, Airport best) greatestPort = airPorts.tMin(x => x.dist(okLat, okLon));

Update: micro-optimizations like this one are just not worth it, engines are so smart these days that I would advice in the 2020 to simply just go with var arr = [];.

Here is how I would do it:

var mynumber = 10;
var arr = new Array(mynumber);

for (var i = 0; i < mynumber; i++) {
    arr[i] = (i + 1).toString();
}

My answer is pretty much the same of everyone, but note that I did something different:

• It is better if you specify the array length and don't force it to expand every time

So I created the array with new Array(mynumber);

If you're working with massive data, a memoized approach would be best:

# First create a dictionary of manually stored values
color_dict = {'Z':'red'}

# Second, build a dictionary of "other" values
color_dict_other = {x:'green' for x in df['Set'].unique() if x not in color_dict.keys()}

# Next, merge the two
color_dict.update(color_dict_other)

# Finally, map it to your column
df['color'] = df['Set'].map(color_dict)

This approach will be fastest when you have many repeated values. My general rule of thumb is to memoize when: data_size > 10**4 & n_distinct < data_size/4

E.x. Memoize in a case 10,000 rows with 2,500 or fewer distinct values.

You can use the TelephonyManager to do this:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = tm.getLine1Number();

The documentation for getLine1Number() says this method will return null if the number is "unavailable", but it does not say when the number might be unavailable.

You'll need to give your application permission to make this query by adding the following to your Manifest:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

(You shouldn't use TelephonyManager.getDefault() to get the TelephonyManager as that is a private undocumented API call and may change in future.)

Note that the performance of Enum.Parse() is awful, because it is implemented via reflection. (The same is true of Enum.ToString, which goes the other way.)

If you need to convert strings to Enums in performance-sensitive code, your best bet is to create a Dictionary<String,YourEnum> at startup and use that to do your conversions.

Install yaml from the PyYAML home pagee: http://www.pyyaml.org/wiki/PyYAML

Select the appropriate version for your OS and Python.

<div style="cursor:pointer" onclick="document.location='http://www.google.com'">Content Goes Here</div>

Every time you call e.nextElement() you take the next object from the iterator. You have to check e.hasMoreElement() between each call.

Example:

while(e.hasMoreElements()){
    String param = e.nextElement();
    System.out.println(param);
}
