It should be "datepicker", not "datePicker" if you are using the jQuery UI DatePicker plugin. Perhaps, you have a different but similar plugin that doesn't support the select handler.

The only way that worked for me is presenting dummy modal view controller.

UIViewController* dummyVC = [[UIViewController alloc] init];
dummyVC.view = [[UIView alloc] init];
[self presentModalViewController:dummyVC animated:NO];
[self dismissModalViewControllerAnimated:NO];

Your VC will be asked for updated interface orientations when modal view controller is dismissed.

Curious thing is that UINavigationController does exactly this when pushing/popping child view controllers with different supported interface orientations (tested on iOS 6.1, 7.0).

I think, better way is use HttpPostedFileBase in your controller or API. After this you can simple detect size, type etc.

File properties you can find here:

MVC3 How to check if HttpPostedFileBase is an image

For example ImageApi:

[HttpPost]
[Route("api/image")]  
public ActionResult Index(HttpPostedFileBase file)  
{  
    if (file != null && file.ContentLength > 0)  
        try 
        {  
            string path = Path.Combine(Server.MapPath("~/Images"),  
               Path.GetFileName(file.FileName));

            file.SaveAs(path);  
            ViewBag.Message = "Your message for success";  
        }  
        catch (Exception ex)  
        {  
            ViewBag.Message = "ERROR:" + ex.Message.ToString();  
        }  
    else 
    {  
        ViewBag.Message = "Please select file";  
    }  
    return View();  
}

Hope it help.

You can accomplish this (if I understand what you are trying to do) using dynamic SQL.

The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.

So you can use something like this approach:

SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue 
    + ' AS fld1 FROM tbl' + @KeyValue

EXEC (@stmt)

First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:

'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'

At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE (or EXEC for short).

The old-school sp_executesql procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.

FOLLOWUP

EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.

Consider what would happen if @KeyValue contained the string:

'1 AS foo; DROP TABLE students; -- '

The string we would produce as a SQL statement would be:

'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'

When we EXECUTE that string as a SQL statement:

INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...

And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)

One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'. If an illegal character is found, then reject the value, and exit without executing any SQL.

here is my solution, it searches for duplicates based on object.prop and when it finds a duplicate object it replaces its value in array1 with array2 value

function mergeSecondArrayIntoFirstArrayByProperty(array1, array2) {
    for (var i = 0; i < array2.length; i++) {
        var found = false;
        for (var j = 0; j < array1.length; j++) {
            if (array2[i].prop === array1[j].prop) { // if item exist in array1
                array1[j] = array2[i]; // replace it in array1 with array2 value
                found = true;
            }
        }
        if (!found) // if item in array2 not found in array1, add it to array1
            array1.push(array2[i]);

    }
    return array1;
}

Make sure that both projects have same target framework version here: right click on project -> properties -> application (tab) -> target framework

Also, make sure that the project "logger" (which you want to include in the main project) has the output type "Class Library" in: right click on project -> properties -> application (tab) -> output type

Finally, Rebuild the solution.

As an alternative to the MONTH and YEAR functions, a regular WHERE clause will work too:

select *
from yourtable
where '2009-01-01' <= datecolumn and datecolumn < '2009-02-01'

We can add swap space in any server

create a file using dd command

 #dd if=/dev/zero of=/swapfile bs=1M count=2048
                    or
 #dd if=/dev/zero of=/swapfile bs=1024M count=2

bs is blocksize and count refers to the size in MB or GB

we can use vice versa

After creation change the permission of file :

 #chmod 600 /swapfile 

Then makeswap the file :

 #mkswap /swapfile 

Then enable the swap file with swapon command :

 #swapon  /swapfile 

Check with free command whether swap is enabled or not :

 #free -h
 #swapon -s

You can use strptime(3) to parse the time, and then mktime(3) to convert it to a time_t:

const char *time_details = "16:35:12";
struct tm tm;
strptime(time_details, "%H:%M:%S", &tm);
time_t t = mktime(&tm);  // t is now your desired time_t

Adding a step-by-step guide to @Codeply-er's answer above for SASS/SCSS newbies like me.

1. Save btnCustom.scss.

/* import the necessary Bootstrap files */
@import 'bootstrap';

/* Define color */
$mynewcolor:#77cccc;

.btn-custom {
    @include button-variant($mynewcolor, darken($mynewcolor, 7.5%), darken($mynewcolor, 10%), lighten($mynewcolor,5%), lighten($mynewcolor, 10%), darken($mynewcolor,30%));
}

.btn-outline-custom {
    @include button-outline-variant($mynewcolor, #222222, lighten($mynewcolor,5%), $mynewcolor);
}

2. Download a SASS compiler such as Koala so that SCSS file above can be compiled to CSS.
3. Clone the Bootstrap github repo because the compiler needs the button-variant mixins somewhere.
4. Explicitly import bootstrap functions by creating a _bootstrap.scss file as below. This will allow the compiler to access the Bootstrap functions and variables.

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/mixins";
@import "bootstrap/scss/root";
@import "bootstrap/scss/reboot";
@import "bootstrap/scss/type";
@import "bootstrap/scss/images";
@import "bootstrap/scss/grid";
@import "bootstrap/scss/tables";
@import "bootstrap/scss/forms";
@import "bootstrap/scss/buttons";
@import "bootstrap/scss/utilities";

5. Compile btnCustom.scss with the previously downloaded compiler to css.

You simply pass the FormControl an array of validators.

Here's an example showing how you can add validators to an existing FormControl:

this.form.controls["firstName"].setValidators([Validators.minLength(1), Validators.maxLength(30)]);

Note, this will reset any existing validators you added when you created the FormControl.

In my case,

    word-break: break-all;

worked perfecly, hope it helps any other newcomer like me.

The host should be specified in each environment's config file. Eg:

config/environments/development.rb

See this question and this question.

Just another approach:

1) Alt+Up and Alt+Down (or Alt+Down and Alt+Up, order does not matter)
2) Ctrl+C

But of course vim's "yy" is the fastest :)

Assuming that you don't have a library or system header that defines NULL as for example (void*)0 or (char*)0 it's fine. I always tend to use 0 myself as it is by definition the null pointer. In c++0x you'll have nullptr available so the question won't matter as much anymore.

a = '123' if b else '456'

One thing i've noticed is: spring CronTrigger is not cron. You may end up with 7 parameters in a valid cron expression (wich you can validate on cronmaker.com) and then spring not accept it. Most of cases you just delete the last parameter and everything works fine.

At the top of this list (when I read it) was valgrind. Valgrind is excellent if you are able to reproduce the leak on a test system. I've used it with great success.

What if you've just noticed that the production system is leaking right now and you have no idea how to reproduce it in test? Some evidence of what's wrong is captured in the state of that production system, and it might be enough to provide an insight on where the problem is so you can reproduce it.

That's where Monte Carlo sampling comes into the picture. Read Raymond Chen's blog article, “The poor man's way of identifying memory leaks” and then check out my implementation (assumes Linux, tested only on x86 and x86-64)

http://github.com/tialaramex/leakdice/tree/master

C++ provides a good mechanism to manage the life time of an object though class/struct constructs. This is one of the best features of C++ over other languages.

When you have member variables exposed through ref or pointer it violates the encapsulation in principle. This idiom enables the consumer of the class to change the state of an object of A without it(A) having any knowledge or control of it. It also enables the consumer to hold on to a ref/pointer to A's internal state, beyond the life time of the object of A. This is bad design. Instead the class could be refactored to hold a ref/pointer to the shared object (not own it) and these could be set using the constructor (Mandate the life time rules). The shared object's class may be designed to support multithreading/concurrency as the case may apply.

For my issue, I didn't want my images scaled to 100% when they weren't intended to be as large as the container.

For my xs container (<768px as .container), not having a fixed width drove the issue, so I put one back on to it (less the 15px col padding).

// Helps bootstrap 3.0 keep images constrained to container width when width isn't set a fixed value (below 768px), while avoiding all images at 100% width.
// NOTE: proper function relies on there being no inline styling on the element being given a defined width ( '.container'  )

function setWidth() {
    width_val = $( window ).width();
    if( width_val < 768 ) {
        $( '.container' ).width( width_val - 30 );
    } else {
        $( '.container' ).removeAttr( 'style' );
    }
}

setWidth();
$( window ).resize( setWidth );

There is another way to have multiple dataSources by using @EnableAutoConfiguration and application.properties.

Basically put multiple dataSource configuration info on application.properties and generate default setup (dataSource and entityManagerFactory) automatically for first dataSource by @EnableAutoConfiguration. But for next dataSource, create dataSource, entityManagerFactory and transactionManager all manually by the info from property file.

Below is my example to setup two dataSources. First dataSource is setup by @EnableAutoConfiguration which can be assigned only for one configuration, not multiple. And that will generate 'transactionManager' by DataSourceTransactionManager, that looks default transactionManager generated by the annotation. However I have seen the transaction not beginning issue on the thread from scheduled thread pool only for the default DataSourceTransactionManager and also when there are multiple transaction managers. So I create transactionManager manually by JpaTransactionManager also for the first dataSource with assigning 'transactionManager' bean name and default entityManagerFactory. That JpaTransactionManager for first dataSource surely resolves the weird transaction issue on the thread from ScheduledThreadPool.

Update for Spring Boot 1.3.0.RELEASE

I found my previous configuration with @EnableAutoConfiguration for default dataSource has issue on finding entityManagerFactory with Spring Boot 1.3 version. Maybe default entityManagerFactory is not generated by @EnableAutoConfiguration, once after I introduce my own transactionManager. So now I create entityManagerFactory by myself. So I don't need to use @EntityScan. So it looks I'm getting more and more out of the setup by @EnableAutoConfiguration.

Second dataSource is setup without @EnableAutoConfiguration and create 'anotherTransactionManager' by manual way.

Since there are multiple transactionManager extends from PlatformTransactionManager, we should specify which transactionManager to use on each @Transactional annotation

Default Repository Config

@Configuration
@EnableTransactionManagement
@EnableAutoConfiguration
@EnableJpaRepositories(
        entityManagerFactoryRef = "entityManagerFactory",
        transactionManagerRef = "transactionManager",
        basePackages = {"com.mysource.repository"})
public class RepositoryConfig {
    @Autowired
    JpaVendorAdapter jpaVendorAdapter;

    @Autowired
    DataSource dataSource;

    @Bean(name = "entityManager")
    public EntityManager entityManager() {
        return entityManagerFactory().createEntityManager();
    }

    @Primary
    @Bean(name = "entityManagerFactory")
    public EntityManagerFactory entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        emf.setDataSource(dataSource);
        emf.setJpaVendorAdapter(jpaVendorAdapter);
        emf.setPackagesToScan("com.mysource.model");
        emf.setPersistenceUnitName("default");   // <- giving 'default' as name
        emf.afterPropertiesSet();
        return emf.getObject();
    }

    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager tm = new JpaTransactionManager();
        tm.setEntityManagerFactory(entityManagerFactory());
        return tm;
    }
}

Another Repository Config

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "anotherEntityManagerFactory",
        transactionManagerRef = "anotherTransactionManager",
        basePackages = {"com.mysource.anothersource.repository"})
public class AnotherRepositoryConfig {
    @Autowired
    JpaVendorAdapter jpaVendorAdapter;

    @Value("${another.datasource.url}")
    private String databaseUrl;

    @Value("${another.datasource.username}")
    private String username;

    @Value("${another.datasource.password}")
    private String password;

    @Value("${another.dataource.driverClassName}")
    private String driverClassName;

    @Value("${another.datasource.hibernate.dialect}")
    private String dialect;

    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource(databaseUrl, username, password);
        dataSource.setDriverClassName(driverClassName);
        return dataSource;
    }

    @Bean(name = "anotherEntityManager")
    public EntityManager entityManager() {
        return entityManagerFactory().createEntityManager();
    }

    @Bean(name = "anotherEntityManagerFactory")
    public EntityManagerFactory entityManagerFactory() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.dialect", dialect);

        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        emf.setDataSource(dataSource());
        emf.setJpaVendorAdapter(jpaVendorAdapter);
        emf.setPackagesToScan("com.mysource.anothersource.model");   // <- package for entities
        emf.setPersistenceUnitName("anotherPersistenceUnit");
        emf.setJpaProperties(properties);
        emf.afterPropertiesSet();
        return emf.getObject();
    }

    @Bean(name = "anotherTransactionManager")
    public PlatformTransactionManager transactionManager() {
        return new JpaTransactionManager(entityManagerFactory());
    }
}

application.properties

# database configuration
spring.datasource.url=jdbc:h2:file:~/main-source;AUTO_SERVER=TRUE
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.continueOnError=true
spring.datasource.initialize=false

# another database configuration
another.datasource.url=jdbc:sqlserver://localhost:1433;DatabaseName=another;
another.datasource.username=username
another.datasource.password=
another.datasource.hibernate.dialect=org.hibernate.dialect.SQLServer2008Dialect 
another.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver

Choose proper transactionManager for @Transactional annotation

Service for first datasource

@Service("mainService")
@Transactional("transactionManager")
public class DefaultDataSourceServiceImpl implements DefaultDataSourceService       
{

   //

}

Service for another datasource

@Service("anotherService")
@Transactional("anotherTransactionManager")
public class AnotherDataSourceServiceImpl implements AnotherDataSourceService 
{

   //

}

This is how I usually do it (sql server).

Create Table Master (
MasterID int identity(1,1) primary key,
Stuff varchar(10)
)
GO
Create Table Detail (
DetailID int identity(1,1) primary key,
MasterID int references Master, --use 'references'
Stuff varchar(10))
GO
Insert into Master values('value')
--(1 row(s) affected)
GO
Insert into Detail values (1, 'Value1') -- Works
--(1 row(s) affected)
insert into Detail values (2, 'Value2') -- Fails
--Msg 547, Level 16, State 0, Line 2
--The INSERT statement conflicted with the FOREIGN KEY constraint "FK__Detail__MasterID__0C70CFB4". 
--The conflict occurred in database "Play", table "dbo.Master", column 'MasterID'.
--The statement has been terminated.

As you can see the second insert into the detail fails because of the foreign key. Here's a good weblink that shows various syntax for defining FK during table creation or after.

http://www.1keydata.com/sql/sql-foreign-key.html

Four years later I came across this again. My current approach is this as it allows for code completion in the IDE as well as type safety:

Base class:

abstract class TypedEnum
{
    private static $_instancedValues;

    private $_value;
    private $_name;

    private function __construct($value, $name)
    {
        $this->_value = $value;
        $this->_name = $name;
    }

    private static function _fromGetter($getter, $value)
    {
        $reflectionClass = new ReflectionClass(get_called_class());
        $methods = $reflectionClass->getMethods(ReflectionMethod::IS_STATIC | ReflectionMethod::IS_PUBLIC);    
        $className = get_called_class();

        foreach($methods as $method)
        {
            if ($method->class === $className)
            {
                $enumItem = $method->invoke(null);

                if ($enumItem instanceof $className && $enumItem->$getter() === $value)
                {
                    return $enumItem;
                }
            }
        }

        throw new OutOfRangeException();
    }

    protected static function _create($value)
    {
        if (self::$_instancedValues === null)
        {
            self::$_instancedValues = array();
        }

        $className = get_called_class();

        if (!isset(self::$_instancedValues[$className]))
        {
            self::$_instancedValues[$className] = array();
        }

        if (!isset(self::$_instancedValues[$className][$value]))
        {
            $debugTrace = debug_backtrace();
            $lastCaller = array_shift($debugTrace);

            while ($lastCaller['class'] !== $className && count($debugTrace) > 0)
            {
                $lastCaller = array_shift($debugTrace);
            }

            self::$_instancedValues[$className][$value] = new static($value, $lastCaller['function']);
        }

        return self::$_instancedValues[$className][$value];
    }

    public static function fromValue($value)
    {
        return self::_fromGetter('getValue', $value);
    }

    public static function fromName($value)
    {
        return self::_fromGetter('getName', $value);
    }

    public function getValue()
    {
        return $this->_value;
    }

    public function getName()
    {
        return $this->_name;
    }
}

Example Enum:

final class DaysOfWeek extends TypedEnum
{
    public static function Sunday() { return self::_create(0); }    
    public static function Monday() { return self::_create(1); }
    public static function Tuesday() { return self::_create(2); }   
    public static function Wednesday() { return self::_create(3); }
    public static function Thursday() { return self::_create(4); }  
    public static function Friday() { return self::_create(5); }
    public static function Saturday() { return self::_create(6); }      
}

Example usage:

function saveEvent(DaysOfWeek $weekDay, $comment)
{
    // store week day numeric value and comment:
    $myDatabase->save('myeventtable', 
       array('weekday_id' => $weekDay->getValue()),
       array('comment' => $comment));
}

// call the function, note: DaysOfWeek::Monday() returns an object of type DaysOfWeek
saveEvent(DaysOfWeek::Monday(), 'some comment');

Note that all instances of the same enum entry are the same:

$monday1 = DaysOfWeek::Monday();
$monday2 = DaysOfWeek::Monday();
$monday1 === $monday2; // true

You can also use it inside of a switch statement:

function getGermanWeekDayName(DaysOfWeek $weekDay)
{
    switch ($weekDay)
    {
        case DaysOfWeek::Monday(): return 'Montag';
        case DaysOfWeek::Tuesday(): return 'Dienstag';
        // ...
}

You can also create an enum entry by name or value:

$monday = DaysOfWeek::fromValue(2);
$tuesday = DaysOfWeek::fromName('Tuesday');

Or you can just get the name (i.e. the function name) from an existing enum entry:

$wednesday = DaysOfWeek::Wednesday()
echo $wednesDay->getName(); // Wednesday

There is no => for if.
Use if %energy% GEQ %m2enc%

See if /? for some other details.

You could use the Laravel query builder, but this is not the best way to do it.

Check Wader's answer below for the Eloquent way - which is better as it allows you to check that there is actually a user that matches the email address, and handle the error if there isn't.

DB::table('users')
        ->where('email', $userEmail)  // find your user by their email
        ->limit(1)  // optional - to ensure only one record is updated.
        ->update(array('member_type' => $plan));  // update the record in the DB. 

If you have multiple fields to update you can simply add more values to that array at the end.

If I remember correctly, Bluetooth defines certain roles that devices can take. Most cell phones only support a certain number of roles. For instance, I can have a Bluetooth stereo headset that connects to my phone to receive audio, but just because my cell phone has Bluetooth does mean that it supports BEING a speaker for a different device - it doesn't advertise its capabilities of having a speaker for use by other Bluetooth devices.

I assume you want to transfer files between two iPhones? Transferring files via Bluetooth does seem like functionality that I would put in the iPhone, but I'm not Apple so I don't know for sure. In fact, yes, it seems that file transfer is not supported except in jailbroken phones:

http://gizmodo.com/5138797/iphone-bluetooth-file-transfer-coming-soon-yes

You'll probably get similar answers for Bluetooth Dial-Up Networking. I'd imagine they kept the Bluetooth commands out of the SDK for various reasons and you'll have to jailbreak your phone to get the functionality back.

Simply Enter Esc and type m it will convert to text cell.

You can just use it like this:

Template t = ve.getTemplate("./src/main/resources/templates/email_html_new.vm");

It works.

When Node.js is not installed using the msi installer, npm needs to be setup manually.

setting up npm

First, let's say we have the node.exe file located in the folder c:\nodejs. Now to setup npm-

1. Download the latest npm release from GitHub (https://github.com/npm/npm/releases)
2. Create folders c:\nodejs\node_modules and c:\nodejs\node_modules\npm
3. Unzip the downloaded zip file in c:\nodejs\node_modules\npm folder
4. Copy npm and npm.cmd files from c:\nodejs\node_modules\npm\bin to c:\nodejs folder

In order to test npm, open cmd.exe change working directory to c:\nodejs and type npm --version. You will see the version of npm if it is setup correctly.

Once setup is done, it can be used to install/uninstall packages locally or globally. For more information on using npm visit https://docs.npmjs.com/.

As the final step you can add node's folder path c:\nodejs to the path environment variable so that you don't have to specify full path when running node.exe and npm at command prompt.

I found another reason for this type of error: in my case, someone set the conf/catalina.properties setting tomcat.util.scan.StandardJarScanFilter.jarsToSkip property to * to avoid log warning messages, thereby skipping the necessary scan by Tomcat. Changing this back to the Tomcat default and adding an appropriate list of jars to skip (not including jstl-1.2 or spring-webmvc) solved the problem.

I found many examples on the Google but there are bad because just remove part of string with "."

Actually that is absolutely the correct thing to do. Go ahead and use that.

The file extension is everything after the last dot, and there is no requirement for a file extension to be any particular number of characters. Even talking only about Windows, it already comes with file extensions that don't fit 3-4 characters, such as eg. .manifest.

Assuming it actually is a symlink,

$ rm -d symlink

It should figure it out, but since it can't we enable the latent code that was intended for another case that no longer exists but happens to do the right thing here.

@echo off

set countfiles=10

:loop

set /a countfiles -= 1

echo hi

if %countfiles% GTR 0 goto loop

pause

on the first "set countfiles" the 10 you see is the amount it will loop the echo hi is the thing you want to loop

This is Atharva's answer from: https://developer.mozilla.org/en-US/docs/Web/API/element.scrollIntoView. Just wanted to add if your document is in an iframe, you can choose an element in the parent frame to scroll into view:

 $('#element-in-parent-frame', window.parent.document).get(0).scrollIntoView();

As of now the best way is to use android:fadeScrollbars="false" in xml which is equivalent to ScrollView.setScrollbarFadingEnabled(false); in java code.

You declare a function pointer variable for the given signature of your functions like this:

bool (* fnptr)();

you can assign it one of your functions:

fnptr = A;

and you can call it:

bool result = fnptr();

You might consider using typedefs to define a type for every distinct function signature you need. This will make the code easier to read and to maintain. i.e. for the signature of functions returning bool with no arguments this could be:

typdef bool (* BoolFn)();

and then you can use like this to declare the function pointer variable for this type:

BoolFn fnptr;

you can find it by running the following command

mysql --help

it will give you the mysql installed directory and all commands for mysql.

brew install cask
brew cask install xquartz
brew tap homebrew/science
brew install r

This way, everything is packager managed, so there's no need to manually download and install anything.

Write-Output should be used when you want to send data on in the pipe line, but not necessarily want to display it on screen. The pipeline will eventually write it to out-default if nothing else uses it first.

Write-Host should be used when you want to do the opposite.

[console]::WriteLine is essentially what Write-Host is doing behind the scenes.

Run this demonstration code and examine the result.

function Test-Output {
    Write-Output "Hello World"
}

function Test-Output2 {
    Write-Host "Hello World" -foreground Green
}

function Receive-Output {
    process { Write-Host $_ -foreground Yellow }
}

#Output piped to another function, not displayed in first.
Test-Output | Receive-Output

#Output not piped to 2nd function, only displayed in first.
Test-Output2 | Receive-Output 

#Pipeline sends to Out-Default at the end.
Test-Output 

You'll need to enclose the concatenation operation in parentheses, so that PowerShell processes the concatenation before tokenizing the parameter list for Write-Host, or use string interpolation

write-host ("count=" + $count)
# or
write-host "count=$count"

BTW - Watch this video of Jeffrey Snover explaining how the pipeline works. Back when I started learning PowerShell I found this to be the most useful explanation of how the pipeline works.

In my case, an aborted Nuget restore-attempt had corrupted one of the packages.configfiles in the solution. I did not discover this before checking my git working tree. After reverting the changes in the file, Nuget restore was working again.

The answer above is correct, but the path is slightly off, try this instead:

%AppData%\..\Local\Temp\TFSTemp

I'm adding another option. The answers above were very useful for me, but I wanted to use jQuery instead of ic-ajax (it seems to have a dependency with Ember when I tried to install through bower). Keep in mind that this solution only works on modern browsers.

In order to implement this on jQuery I used jQuery BinaryTransport. This is a nice plugin to read AJAX responses in binary format.

Then you can do this to download the file and send the headers:

$.ajax({
    url: url,
    type: 'GET',
    dataType: 'binary',
    headers: headers,
    processData: false,
    success: function(blob) {
        var windowUrl = window.URL || window.webkitURL;
        var url = windowUrl.createObjectURL(blob);
        anchor.prop('href', url);
        anchor.prop('download', fileName);
        anchor.get(0).click();
        windowUrl.revokeObjectURL(url);
    }
});

The vars in the above script mean:

• url: the URL of the file
• headers: a Javascript object with the headers to send
• fileName: the filename the user will see when downloading the file
• anchor: it is a DOM element that is needed to simulate the download that must be wrapped with jQuery in this case. For example $('a.download-link').

tsc is not recognized as internal or external command

As mentioned in another answer this is because tsc is not present in path.

1. Install as global package

To make TypeScript compiler available to all directories for this user, run the below command:

npm install -g typescript

You will see something similar to

C:\Users\username\AppData\Roaming\npm\tsserver -> C:\Users\username\AppData\Roaming\npm\node_modules\typescript\bin\tsserver C:\Users\username\AppData\Roaming\npm\tsc -> C:\Users\username\AppData\Roaming\npm\node_modules\typescript\bin\tsc + [email protected] added 1 package from 1 contributor in 4.769s

2. Set the environment variable

• Add the npm installation folder to your "user variables" AND "environment variables".

• In windows you can add environment variable PATH with value

  C:\Users\username\AppData\Roaming\npm\

i.e. wherever the npm installation folder is present.

Note: If multiple Paths are present separate them with a ;(semicolon)

If the below command gives the version then you have successfully installed

tsc --version

This should work to get a specific column out of the command output "docker images":

Operators                           Overloadability

+, -, *, /, %, &, |, <<, >>         All C# binary operators can be overloaded.

+, -, !,  ~, ++, --, true, false    All C# unary operators can be overloaded.

==, !=, <, >, <= , >=               All relational operators can be overloaded, 
                                    but only as pairs.

&&, ||                  They can't be overloaded

() (Conversion operator)        They can't be overloaded

+=, -=, *=, /=, %=                  These compound assignment operators can be 
                                    overloaded. But in C#, these operators are
                                    automatically overloaded when the respective
                                    binary operator is overloaded.

=, . , ?:, ->, new, is, as, sizeof  These operators can't be overloaded

    [ ]                             Can be overloaded but not always!

Source of the information

For bracket:

public Object this[int index]
{

}

BUT

The array indexing operator cannot be overloaded; however, types can define indexers, properties that take one or more parameters. Indexer parameters are enclosed in square brackets, just like array indices, but indexer parameters can be declared to be of any type (unlike array indices, which must be integral).

Just sharing something that helped me and may be useful for others. Although most of the answers here are correct, by using the getActionBar().setDisplayHomeAsUpEnabled(true);, this wasn't working for me. The issue I had was that I was trying to create a second Activity manually, but there are more details involved.
What really solved my problem was following Android Developers tutorial (https://developer.android.com/training/basics/firstapp/starting-activity) for creating a second Activity using Android Studio own tools:

Create the second activity
1. In the Project window, right-click the app folder and select New > Activity > Empty Activity.
2. In the Configure Activity window, enter "DisplayMessageActivity" for Activity Name and click Finish (leave all other properties set to the defaults).
Android Studio automatically does three things:
- Creates the DisplayMessageActivity file.
- Creates the corresponding activity_display_message.xml layout file.
- Adds the required <activity> element in AndroidManifest.xml.

You need to do this:

OleDbConnection connection = new OleDbConnection(
    "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet DS = new DataSet();
connection.Open();

string query = 
    @"SELECT tbl_Computer.*,  tbl_Besitzer.*
    FROM tbl_Computer 
    INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
    WHERE (((tbl_Besitzer.Vorname)='ma'))";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection); 
DBAdapter.Fill(DS);

By the way, what is this DataSet1? This should be "DataSet".

I wasn't able to do this:

UPDATE users SET created = NULL WHERE created = '0000-00-00 00:00:00'

(on MySQL 5.7.13).

I kept getting the Incorrect datetime value: '0000-00-00 00:00:00' error.

Strangely, this worked: SELECT * FROM users WHERE created = '0000-00-00 00:00:00'. I have no idea why the former fails and the latter works... maybe a MySQL bug?

At any case, this UPDATE query worked:

UPDATE users SET created = NULL WHERE CAST(created AS CHAR(20)) = '0000-00-00 00:00:00'

Some big picture perspective to add to the other useful but more detail-centric answers:

In Swift, the exclamation point appears in several contexts:

• Forced unwrapping: let name = nameLabel!.text
• Implicitly unwrapped optionals: var logo: UIImageView!
• Forced casting: logo.image = thing as! UIImage
• Unhandled exceptions: try! NSJSONSerialization.JSONObjectWithData(data, [])

Every one of these is a different language construct with a different meaning, but they all have three important things in common:

1. Exclamation points circumvent Swift’s compile-time safety checks.

When you use ! in Swift, you are essentially saying, “Hey, compiler, I know you think an error could happen here, but I know with total certainty that it never will.”

Not all valid code fits into the box of Swift’s compile-time type system — or any language’s static type checking, for that matter. There are situations where you can logically prove that an error will never happen, but you can’t prove it to the compiler. That’s why Swift’s designers added these features in the first place.

However, whenever you use !, you’re ruling out having a recovery path for an error, which means that…

2. Exclamation points are potential crashes.

An exclamation point also says, “Hey Swift, I am so certain that this error can never happen that it’s better for you to crash my whole app than it is for me to code a recovery path for it.”

That’s a dangerous assertion. It can be the correct one: in mission-critical code where you have thought hard about your code’s invariants, it may be that bogus output is worse than a crash.

However, when I see ! in the wild, it's rarely used so mindfully. Instead, it too often means, “this value was optional and I didn’t really think too hard about why it could be nil or how to properly handle that situation, but adding ! made it compile … so my code is correct, right?”

Beware the arrogance of the exclamation point. Instead…

3. Exclamation points are best used sparingly.

Every one of these ! constructs has a ? counterpart that forces you to deal with the error/nil case:

• Conditional unwrapping: if let name = nameLabel?.text { ... }
• Optionals: var logo: UIImageView?
• Conditional casts: logo.image = thing as? UIImage
• Nil-on-failure exceptions: try? NSJSONSerialization.JSONObjectWithData(data, [])

If you are tempted to use !, it is always good to consider carefully why you are not using ? instead. Is crashing your program really the best option if the ! operation fails? Why is that value optional/failable?

Is there a reasonable recovery path your code could take in the nil/error case? If so, code it.

If it can’t possibly be nil, if the error can never happen, then is there a reasonable way to rework your logic so that the compiler knows that? If so, do it; your code will be less error-prone.

There are times when there is no reasonable way to handle an error, and simply ignoring the error — and thus proceeding with wrong data — would be worse than crashing. Those are the times to use force unwrapping.

I periodically search my entire codebase for ! and audit every use of it. Very few usages stand up to scrutiny. (As of this writing, the entire Siesta framework has exactly two instances of it.)

That’s not to say you should never use ! in your code — just that you should use it mindfully, and never make it the default option.

In my case the image file had just been written to and needed to be flushed before opening, like so:

img_file.flush() 
img = Image.open(img_file.name))

The jquery.selectboxes.js plugin has a sort method. You can implement the plugin, or dive into the code to see a way to sort the options.

You can use .delay() before an animation, like this:

$("#myElem").show().delay(5000).fadeOut();

If it's not an animation, use setTimeout() directly, like this:

$("#myElem").show();
setTimeout(function() { $("#myElem").hide(); }, 5000);

You do the second because .hide() wouldn't normally be on the animation (fx) queue without a duration, it's just an instant effect.

Or, another option is to use .delay() and .queue() yourself, like this:

$("#myElem").show().delay(5000).queue(function(n) {
  $(this).hide(); n();
});

If all steps (in existing answers) dont work , Just close eclipse and again open eclipse .

It is usually not recommended to call flush explicitly unless it is necessary. Hibernate usually auto calls Flush at the end of the transaction and we should let it do it's work. Now, there are some cases where you might need to explicitly call flush where a second task depends upon the result of the first Persistence task, both being inside the same transaction.

For example, you might need to persist a new Entity and then use the Id of that Entity to do some other task inside the same transaction, on that case it's required to explicitly flush the entity first.

@Transactional
void someServiceMethod(Entity entity){
    em.persist(entity); 
    em.flush() //need to explicitly flush in order to use id in next statement
    doSomeThingElse(entity.getId());    
}

Also Note that, explicitly flushing does not cause a database commit, a database commit is done only at the end of a transaction, so if any Runtime error occurs after calling flush the changes would still Rollback.

open etc folder in netbeans folder then edit the netbeans.conf with notepad and you will find a line like this :

Default location of JDK, can be overridden by using --jdkhome :
netbeans_jdkhome="G:\Program Files\Java\jdk1.6.0_13"

here you can set your jdk version.

All do not work for me on eloquent collections, laravel eloquent collections use the key from the items I think which causes merging issues, you need to get the first collection back as an array, put that into a fresh collection and then push the others into the new collection;

public function getFixturesAttribute()
{
    $fixtures = collect( $this->homeFixtures->all() );
    $this->awayFixtures->each( function( $fixture ) use ( $fixtures ) {
        $fixtures->push( $fixture );
    });
    return $fixtures;
}

To get value, use:

$.each($('input'),function(i,val){
    if($(this).attr("type")=="hidden"){
        var valueOfHidFiled=$(this).val();
        alert(valueOfHidFiled);
    }
});

or:

var valueOfHidFiled=$('input[type=hidden]').val();
alert(valueOfHidFiled);

To set value, use:

$('input[type=hidden]').attr('value',newValue);

In Jekyll I was able to add some color or other styles to a bold element (should work with all other elements as well).

I started the "styling" with {: and end it }. There is no space allowed between element and curly bracket!

**My Bold Text, in red color.**{: style="color: red; opacity: 0.80;" }

Will be translated to html:

<strong style="color: red; opacity: 0.80;">My Bold Text, in red color.</strong>

you could try to create the same script that popups that error, dividing the script into several script by importing from external script. Example, hello.py expect an error Memory error, so i divide hello.py into several scripts h.py e.py ll.py o.py all of them have to get into a folder "hellohello" into that folder create init.py into init write import h,e,ll,o and then on ide you write import hellohello

Oh, god! After spending several hours and downloading the Android sources, I have finally come to a solution.

If you look at the Activity class, you will see, that finish() method only sends back the result if there is a mParent property set to null. Otherwise the result is lost.

public void finish() {
    if (mParent == null) {
        int resultCode;
        Intent resultData;
        synchronized (this) {
            resultCode = mResultCode;
            resultData = mResultData;
        }
        if (Config.LOGV) Log.v(TAG, "Finishing self: token=" + mToken);
        try {
            if (ActivityManagerNative.getDefault()
                .finishActivity(mToken, resultCode, resultData)) {
                mFinished = true;
            }
        } catch (RemoteException e) {
            // Empty
        }
    } else {
        mParent.finishFromChild(this);
    }
}

So my solution is to set result to the parent activity if present, like that:

Intent data = new Intent();
 [...]
if (getParent() == null) {
    setResult(Activity.RESULT_OK, data);
} else {
    getParent().setResult(Activity.RESULT_OK, data);
}
finish();

I hope that will be helpful if someone looks for this problem workaround again.

Try to show the pop like below

findViewById(R.id.main_layout).post(new Runnable() {
        public void run() {
            mPopupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.CENTER, 0, 0);
            Button close = (Button) customView.findViewById(R.id.btn_ok);
            close.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    mPopupWindow.dismiss();
                    doOtherStuff();
                }
            });
        }
    });

const RESULT = {
    INCOMPLETE: "incomplete",

}

We'll need a function that can check for the result. The function will check for a succession of chars. What ever the state of the board is, the result is one of 4 options: either Incomplete, player X won, Player O won or a tie.

Our getBestMove function will receive the state of the board, and the symbol of the player for which we want to determine the best possible move. Our function will check all possible moves with the getResult function. If it is a win it will give it a score of 1. if it's a loose it will get a score of -1, a tie will get a score of 0. If it is undetermined we will call the getBestMove function with the new state of the board and the opposite symbol. Since the next move is of the oponent, his victory is the lose of the current player, and the score will be negated. At the end possible move receives a score of either 1,0 or -1, we can sort the moves, and return the move with the highest score.

Since Spring 4.2 you can use @EventListener (documentation)

@Component
class MyClassWithEventListeners {

    @EventListener({ContextRefreshedEvent.class})
    void contextRefreshedEvent() {
        System.out.println("a context refreshed event happened");
    }
}

The ng-model and ng-checked directives should not be used together

From the Docs:

ngChecked

Sets the checked attribute on the element, if the expression inside ngChecked is truthy.

Note that this directive should not be used together with ngModel, as this can lead to unexpected behavior.

— AngularJS ng-checked Directive API Reference

Instead set the desired initial value from the controller:

<input type="checkbox" name="test" ng-model="testModel['item1']" ?n?g?-?c?h?e?c?k?e?d?=?"?t?r?u?e?"? />
    Testing<br />
<input type="checkbox" name="test" ng-model="testModel['item2']" /> Testing 2<br />
<input type="checkbox" name="test" ng-model="testModel['item3']" /> Testing 3<br />
<input type="button" ng-click="submit()" value="Submit" />

$scope.testModel = { item1: true };

It sounds like you have installed SQL Server 2005 Express Edition, which does not include SSIS or the Business Intelligence Development Studio.

BIDS is only provided with the (not free) Standard, Enterprise and Developer Editions.

EDIT

This information was correct for SQL Server 2005. Since SQL Server 2014, Developer Edition has been free. BIDS has been replaced by SQL Server Data Tools, a free plugin for Visual Studio (including the free Visual Studio Community Edition).

For me, I had encountered this error when invoking a webservice call, make sure that the site has a valid ssl, i.e the logo on the side of the url is checked, otherwise need to add the certificate to trusted key store in your machine

You can use

slack://

in order to open the Slack desktop application. For example, on mac, I've run:

open slack://

from the terminal and it opens the Mac desktop Slack application. Still, I didn't figure out the URL that should be used for opening a certain team, channel or message.

When you write the following line of code in TypeScript:

var SUCSS = {};

The type of SUCSS is inferred from the assignment (i.e. it is an empty object type).

You then go on to add a property to this type a few lines later:

SUCSS.fadeDiv = //...

And the compiler warns you that there is no property named fadeDiv on the SUCSS object (this kind of warning often helps you to catch a typo).

You can either... fix it by specifying the type of SUCSS (although this will prevent you from assigning {}, which doesn't satisfy the type you want):

var SUCSS : {fadeDiv: () => void;};

Or by assigning the full value in the first place and let TypeScript infer the types:

var SUCSS = {
    fadeDiv: function () {
        // Simplified version
        alert('Called my func');
    }
};

As of 2018-04-20 Git for Windows has a bug which effectively limits the file size to 4GB max using that particular implementation (this bug propagates to lfs as well).

@ECHO OFF
SETLOCAL
set file=C:\Users\l72rugschiri\Desktop\fs.cfg
FOR %%i IN ("%file%") DO (
ECHO filedrive=%%~di
ECHO filepath=%%~pi
ECHO filename=%%~ni
ECHO fileextension=%%~xi
)

Not really sure what you mean by no "function"

Obviously, change ECHO to SET to set the variables rather thon ECHOing them...

See for documentation for a full list.

ceztko's test case (for reference)

@ECHO OFF
SETLOCAL
set file="C:\Users\ l72rugschiri\Desktop\fs.cfg"
FOR /F "delims=" %%i IN ("%file%") DO (
ECHO filedrive=%%~di
ECHO filepath=%%~pi
ECHO filename=%%~ni
ECHO fileextension=%%~xi
)

Comment : please see comments.

Check Your Skype, I had the problem because skype reserved port 80 for incoming calls, I unchecked it , and it works fine.

Based from Google documentation,

If you want to test your app on the emulator, expand the directory for Android 4.2.2 (API 17) or a higher version, select Google APIs, and install it. Then create a new AVD with Google APIs as the platform target.

Try to navigate to settings--> apps in your emulator and then find Google Play Services. Check the version number and use it in you build.gradle. To update it with the latest version, you can see it in these documentation and SO question.

Basically the zip function works on lists, tuples and dictionaries in Python. If you are using IPython then just type zip? And check what zip() is about.

If you are not using IPython then just install it: "pip install ipython"

For lists

a = ['a', 'b', 'c']
b = ['p', 'q', 'r']
zip(a, b)

The output is [('a', 'p'), ('b', 'q'), ('c', 'r')

For dictionary:

c = {'gaurav':'waghs', 'nilesh':'kashid', 'ramesh':'sawant', 'anu':'raje'}
d = {'amit':'wagh', 'swapnil':'dalavi', 'anish':'mane', 'raghu':'rokda'}
zip(c, d)

The output is:

[('gaurav', 'amit'),
 ('nilesh', 'swapnil'),
 ('ramesh', 'anish'),
 ('anu', 'raghu')]

just place your fonts inside app/assets/fonts folder and set the autoload path when app start using writing the code in application.rb

config.assets.paths << Rails.root.join("app", "assets", "fonts") and

then use the following code in css.

@font-face {

 font-family: 'icomoon';
 src: asset-url('icomoon.eot');
 src: asset-url('icomoon.eot') format('embedded-opentype'),
      asset-url('icomoon.woff') format('woff'),
      asset-url('icomoon.ttf') format('truetype'),
      asset-url('icomoon.svg') format('svg');
 font-weight: normal;
 font-style: normal;

}

Give it a try.

Thanks

In my case I used blow code for different environment.

  document.cookie = name +`=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;Domain=.${document.domain.split('.').splice(1).join('.')}`;

Here is an alternative way to get an object's property value:

write-host $(get-something).SomeProp

you can use the shell(bash for example)

$ string="12 BBQ ,45 rofl, 89 lol"
$ echo ${string% rofl*}
12 BBQ ,45
$ string=${string% rofl*}
$ echo ${string##*,}
45

Both are correct. Oracle allows the use of both.

Based on all that people had to say here on the answers, its just a combination of keydown(not keyup) + preventDefault() + insert a tab character at the caret. Something like:

var keyCode = e.keyCode || e.which;
if (keyCode == 9) {
   e.preventDefault();
   insertAtCaret('txt', '\t')
}

The earlier answer had a working jsfiddle but it used an alert() on keydown. If you remove this alert, then it didnt work. I ve just added a function to insert a tab at the current cursor position in the textarea.

Here s a working jsfiddle for the same: http://jsfiddle.net/nsHGZ/

For the complete system you can add the Microsoft.VisualBasic Framework as a reference;

 Console.WriteLine("You have {0} bytes of RAM",
        new Microsoft.VisualBasic.Devices.ComputerInfo().TotalPhysicalMemory);
        Console.ReadLine();

You probably need to wrap the UNION in a sub-SELECT and apply the WHERE clause afterward:

SELECT * FROM (
    SELECT * FROM Table1 WHERE Field1 = Value1
    UNION
    SELECT * FROM Table2 WHERE Field1 = Value2
) AS t WHERE Field2 = Value3

Basically, the UNION is looking for two complete SELECT statements to combine, and the WHERE clause is part of the SELECT statement.

It may make more sense to apply the outer WHERE clause to both of the inner queries. You'll probably want to benchmark the performance of both approaches and see which works better for you.

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

You will need to return the result of RedirectToAction.

This will both show the input in uppercase and send the input data through post in uppercase.

HTML

<input type="text" id="someInput">

JavaScript

var someInput = document.querySelector('#someInput');
someInput.addEventListener('input', function () {
    someInput.value = someInput.value.toUpperCase();
});

To remove the 'days' text element, you can also make use of the dt() accessor for series: https://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.dt.html

So,

df[['A','B']] = df[['A','B']].apply(pd.to_datetime) #if conversion required
df['C'] = (df['B'] - df['A']).dt.days

which returns:

             A          B   C
one 2014-01-01 2014-02-28  58
two 2014-02-03 2014-03-01  26

You can also get the colors from your resources by using:

dateView.setDivider(new ColorDrawable(_context.getResources().getColor(R.color.textlight)));
dateView.setDividerHeight(1);

Still using indirect. Say your A1 cell is your variable that will contain the name of the referenced sheet (Jan). If you go by:

=INDIRECT(CONCATENATE("'",A1," Item'", "!J3"))

Then you will have the 'Jan Item'!J3 value.

In Python, this:

my_object.method("foo")

...is syntactic sugar, which the interpreter translates behind the scenes into:

MyClass.method(my_object, "foo")

...which, as you can see, does indeed have two arguments - it's just that the first one is implicit, from the point of view of the caller.

This is because most methods do some work with the object they're called on, so there needs to be some way for that object to be referred to inside the method. By convention, this first argument is called self inside the method definition:

class MyNewClass:

    def method(self, arg):
        print(self)
        print(arg)

If you call method("foo") on an instance of MyNewClass, it works as expected:

>>> my_new_object = MyNewClass()
>>> my_new_object.method("foo")
<__main__.MyNewClass object at 0x29045d0>
foo

Occasionally (but not often), you really don't care about the object that your method is bound to, and in that circumstance, you can decorate the method with the builtin staticmethod() function to say so:

class MyOtherClass:

    @staticmethod
    def method(arg):
        print(arg)

...in which case you don't need to add a self argument to the method definition, and it still works:

>>> my_other_object = MyOtherClass()
>>> my_other_object.method("foo")
foo

You can use this configuration:

-startup

It is easy to create a self-signed certificate, import it, and bind it to your website.

1.) Create a self-signed certificate:

Run the following 4 commands, one at a time, from an elevated Command Prompt:

cd C:\Program Files (x86)\Windows Kits\8.1\bin\x64

makecert -r -n "CN=localhost" -b 01/01/2000 -e 01/01/2099 -eku 1.3.6.1.5.5.7.3.3 -sv localhost.pvk localhost.cer

cert2spc localhost.cer localhost.spc

pvk2pfx -pvk localhost.pvk -spc localhost.spc -pfx localhost.pfx

2.) Import certificate to Trusted Root Certification Authorities store:

start --> run --> mmc.exe --> Certificates plugin --> "Trusted Root Certification Authorities" --> Certificates

Right-click Certificates --> All Tasks --> Import Find your "localhost" Certificate at C:\Program Files (x86)\Windows Kits\8.1\bin\x64\

3.) Bind certificate to website:

start --> (IIS) Manager --> Click on your Server --> Click on Sites --> Click on your top level site --> Bindings

Add or edit a binding for https and select the SSL certificate called "localhost".

4.) Import Certificate to Chrome:

Chrome Settings --> Manage Certificates --> Import .pfx certificate from C:\certificates\ folder

Test Certificate by opening Chrome and navigating to https://localhost/

sudo apt-get install libcurl4-openssl-dev

From the man page:

-d delim The first character of delim is used to terminate the input line, rather than newline.

You are using -d, which will terminate the input line on the comma. It will not read the rest of the line. That's why $y is empty.

The regex you need is /(.)\1{9,}/.

Test:

#!perl
use warnings;
use strict;
my $regex = qr/(.)\1{9,}/;
print "NO" if "abcdefghijklmno" =~ $regex;
print "YES" if "------------------------" =~ $regex;
print "YES" if "========================" =~ $regex;

Here the \1 is called a backreference. It references what is captured by the dot . between the brackets (.) and then the {9,} asks for nine or more of the same character. Thus this matches ten or more of any single character.

Although the above test script is in Perl, this is very standard regex syntax and should work in any language. In some variants you might need to use more backslashes, e.g. Emacs would make you write \(.\)\1\{9,\} here.

If a whole string should consist of 9 or more identical characters, add anchors around the pattern:

my $regex = qr/^(.)\1{9,}$/;

Try these:

#dialog_style1 .ui-dialog-titlebar { display:none; }
#dialog_style2 .ui-dialog-titlebar { color:#aaa; }

The best recommendation I can give for you is to load the page in Firefox, open the dialog and inspect it with Firebug, then try different selectors in the console, and see what works. You may need to use some of the other descendant selectors.

I've had good results with this one. Much easier to use than Sharpen.

I just wrote a blog post on saving an object's data to Binary, XML, or Json. It sounds like you probably want to use Binary serialization, but perhaps you want the files to be edited outside of your app, in which case XML or Json might be better. Here are the functions to do it in the various formats. See my blog post for more details.

Binary

/// <summary>
/// Writes the given object instance to a binary file.
/// <para>Object type (and all child types) must be decorated with the [Serializable] attribute.</para>
/// <para>To prevent a variable from being serialized, decorate it with the [NonSerialized] attribute; cannot be applied to properties.</para>
/// </summary>
/// <typeparam name="T">The type of object being written to the XML file.</typeparam>
/// <param name="filePath">The file path to write the object instance to.</param>
/// <param name="objectToWrite">The object instance to write to the XML file.</param>
/// <param name="append">If false the file will be overwritten if it already exists. If true the contents will be appended to the file.</param>
public static void WriteToBinaryFile<T>(string filePath, T objectToWrite, bool append = false)
{
    using (Stream stream = File.Open(filePath, append ? FileMode.Append : FileMode.Create))
    {
        var binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
        binaryFormatter.Serialize(stream, objectToWrite);
    }
}

/// <summary>
/// Reads an object instance from a binary file.
/// </summary>
/// <typeparam name="T">The type of object to read from the XML.</typeparam>
/// <param name="filePath">The file path to read the object instance from.</param>
/// <returns>Returns a new instance of the object read from the binary file.</returns>
public static T ReadFromBinaryFile<T>(string filePath)
{
    using (Stream stream = File.Open(filePath, FileMode.Open))
    {
        var binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
        return (T)binaryFormatter.Deserialize(stream);
    }
}

XML

Requires the System.Xml assembly to be included in your project.

/// <summary>
/// Writes the given object instance to an XML file.
/// <para>Only Public properties and variables will be written to the file. These can be any type though, even other classes.</para>
/// <para>If there are public properties/variables that you do not want written to the file, decorate them with the [XmlIgnore] attribute.</para>
/// <para>Object type must have a parameterless constructor.</para>
/// </summary>
/// <typeparam name="T">The type of object being written to the file.</typeparam>
/// <param name="filePath">The file path to write the object instance to.</param>
/// <param name="objectToWrite">The object instance to write to the file.</param>
/// <param name="append">If false the file will be overwritten if it already exists. If true the contents will be appended to the file.</param>
public static void WriteToXmlFile<T>(string filePath, T objectToWrite, bool append = false) where T : new()
{
    TextWriter writer = null;
    try
    {
        var serializer = new XmlSerializer(typeof(T));
        writer = new StreamWriter(filePath, append);
        serializer.Serialize(writer, objectToWrite);
    }
    finally
    {
        if (writer != null)
            writer.Close();
    }
}

/// <summary>
/// Reads an object instance from an XML file.
/// <para>Object type must have a parameterless constructor.</para>
/// </summary>
/// <typeparam name="T">The type of object to read from the file.</typeparam>
/// <param name="filePath">The file path to read the object instance from.</param>
/// <returns>Returns a new instance of the object read from the XML file.</returns>
public static T ReadFromXmlFile<T>(string filePath) where T : new()
{
    TextReader reader = null;
    try
    {
        var serializer = new XmlSerializer(typeof(T));
        reader = new StreamReader(filePath);
        return (T)serializer.Deserialize(reader);
    }
    finally
    {
        if (reader != null)
            reader.Close();
    }
}

Json

You must include a reference to Newtonsoft.Json assembly, which can be obtained from the Json.NET NuGet Package.

/// <summary>
/// Writes the given object instance to a Json file.
/// <para>Object type must have a parameterless constructor.</para>
/// <para>Only Public properties and variables will be written to the file. These can be any type though, even other classes.</para>
/// <para>If there are public properties/variables that you do not want written to the file, decorate them with the [JsonIgnore] attribute.</para>
/// </summary>
/// <typeparam name="T">The type of object being written to the file.</typeparam>
/// <param name="filePath">The file path to write the object instance to.</param>
/// <param name="objectToWrite">The object instance to write to the file.</param>
/// <param name="append">If false the file will be overwritten if it already exists. If true the contents will be appended to the file.</param>
public static void WriteToJsonFile<T>(string filePath, T objectToWrite, bool append = false) where T : new()
{
    TextWriter writer = null;
    try
    {
        var contentsToWriteToFile = JsonConvert.SerializeObject(objectToWrite);
        writer = new StreamWriter(filePath, append);
        writer.Write(contentsToWriteToFile);
    }
    finally
    {
        if (writer != null)
            writer.Close();
    }
}

/// <summary>
/// Reads an object instance from an Json file.
/// <para>Object type must have a parameterless constructor.</para>
/// </summary>
/// <typeparam name="T">The type of object to read from the file.</typeparam>
/// <param name="filePath">The file path to read the object instance from.</param>
/// <returns>Returns a new instance of the object read from the Json file.</returns>
public static T ReadFromJsonFile<T>(string filePath) where T : new()
{
    TextReader reader = null;
    try
    {
        reader = new StreamReader(filePath);
        var fileContents = reader.ReadToEnd();
        return JsonConvert.DeserializeObject<T>(fileContents);
    }
    finally
    {
        if (reader != null)
            reader.Close();
    }
}

Example

// To save the characterSheet variable contents to a file.
WriteToBinaryFile<CharacterSheet>("C:\CharacterSheet.pfcsheet", characterSheet);

// To load the file contents back into a variable.
CharacterSheet characterSheet = ReadFromBinaryFile<CharacterSheet>("C:\CharacterSheet.pfcsheet");

One answer I'm missing here: Multi-layer perceptron is able to find relation between features. For example it is necessary in computer vision when a raw image is provided to the learning algorithm and now Sophisticated features are calculated. Essentially the intermediate levels can calculate new unknown features.

Best:

 std::string subCondition;

This creates an empty string.

This:

std::string myStr = "";

does a copy initialization - creates a temporary string from "", and then uses the copy constructor to create myStr.

Bonus:

std::string myStr("");

does a direct initialization and uses the string(const char*) constructor.

To check if a string is empty, just use empty().

The only proper way to put server side data into generated javascript code:

<?php $jsString= 'testing'; ?>
<html>
  <body>
    <script type="text/javascript">      
      var jsStringFromPhp=<?php echo json_encode($jsString); ?>;
      alert(jsStringFromPhp);
    </script>
  </body>
</html>

With simple quotes the content of your variable is not escaped against HTML and javascript, so it is vulnerable by XSS attacks...

For similar reasons I recommend to use document.createTextNode() instead of setting the innerHTML. Ofc. it is slower, but more secure...

You can use Random.Next(int maxValue):

Return: A 32-bit signed integer greater than or equal to zero, and less than maxValue; that is, the range of return values ordinarily includes zero but not maxValue. However, if maxValue equals zero, maxValue is returned.

var r = new Random();
// print random integer >= 0 and  < 100
Console.WriteLine(r.Next(100));

For this case however you could use Random.Next(int minValue, int maxValue), like this:

// print random integer >= 1 and < 101
Console.WriteLine(r.Next(1, 101);)
// or perhaps (if you have this specific case)
Console.WriteLine(r.Next(100) + 1);

This solution uses a proxy class and offers the following advantages:

• Allows the consumer to leverage the power of RXJS
• More compact than other solutions proposed so far
• More typesafe than using ngOnChanges()

Example usage:

@Input()
public num: number;
numChanges$ = observeProperty(this as MyComponent, 'num');

Utility function:

export function observeProperty<T, K extends keyof T>(target: T, key: K) {
  const subject = new BehaviorSubject<T[K]>(target[key]);
  Object.defineProperty(target, key, {
    get(): T[K] { return subject.getValue(); },
    set(newValue: T[K]): void {
      if (newValue !== subject.getValue()) {
        subject.next(newValue);
      }
    }
  });
  return subject;
}

                    $(this).focus();
            // fire this step
    }

Try the Apache Commons HttpClient library instead of trying to roll your own: http://hc.apache.org/httpclient-3.x/index.html

From their sample code:

  HttpClient httpclient = new HttpClient();
  httpclient.getHostConfiguration().setProxy("myproxyhost", 8080);

  /* Optional if authentication is required.
  httpclient.getState().setProxyCredentials("my-proxy-realm", " myproxyhost",
   new UsernamePasswordCredentials("my-proxy-username", "my-proxy-password"));
  */

  PostMethod post = new PostMethod("https://someurl");
  NameValuePair[] data = {
     new NameValuePair("user", "joe"),
     new NameValuePair("password", "bloggs")
  };
  post.setRequestBody(data);
  // execute method and handle any error responses.
  // ...
  InputStream in = post.getResponseBodyAsStream();
  // handle response.


  /* Example for a GET reqeust
  GetMethod httpget = new GetMethod("https://someurl");
  try { 
    httpclient.executeMethod(httpget);
    System.out.println(httpget.getStatusLine());
  } finally {
    httpget.releaseConnection();
  }
  */

In my case, it was due to Same Origin policies. To explain it further, MDN states the following:

If the iframe and the iframe's parent document are Same Origin, returns a Document (that is, the active document in the inline frame's nested browsing context), else returns null.

Here's what I use at the top of all my batch files. I just copy/paste from my template folder.

@echo off
:: --HAS ENDING BACKSLASH
set batdir=%~dp0
:: --MISSING ENDING BACKSLASH
:: set batdir=%CD%
pushd "%batdir%"

Setting current batch file's path to %batdir% allows you to call it in subsequent stmts in current batch file, regardless of where this batch file changes to. Using PUSHD allows you to use POPD to quickly set this batch file's path to original %batdir%. Remember, if using %batdir%ExtraDir or %batdir%\ExtraDir (depending on which version used above, ending backslash or not) you will need to enclose the entire string in double quotes if path has spaces (i.e. "%batdir%ExtraDir"). You can always use PUSHD %~dp0. [https: // ss64.com/ nt/ syntax-args .html] has more on (%~) parameters.

Note that using (::) at beginning of a line makes it a comment line. More importantly, using :: allows you to include redirectors, pipes, special chars (i.e. < > | etc) in that comment.

:: ORIG STMT WAS: dir *.* | find /v "1917" > outfile.txt

Of course, Powershell does this and lots more.

Here's a different way of looking at it, and it's a simple one-liner:

int spaces = s.replaceAll("[^ ]", "").length();

This works by effectively removing all non-spaces then taking the length of what’s left (the spaces).

You might want to add a null check:

int spaces = s == null ? 0 : s.replaceAll("[^ ]", "").length();

Java 8 update

You can use a stream too:

int spaces = s.chars().filter(c -> c == (int)' ').count();

using namespace std;

class A {
   public:
     A( int x ) : n( x ){}
     void print() { cout << n << endl; }

};

void func( A p ) {
   p.print();
}

int main () {
   A a;
   func ( a );
}

Of course, you should probably be using references to pass the object, but I suspect you haven't got to them yet.

If you want to build DOM you can use jsdom.

There's also cheerio, it has the jQuery interface and it's a lot faster than older versions of jsdom, although these days they are similar in performance.

You might wanna have a look at htmlparser2, which is a streaming parser, and according to its benchmark, it seems to be faster than others, and no DOM by default. It can also produce a DOM, as it is also bundled with a handler that creates a DOM. This is the parser that is used by cheerio.

parse5 also looks like a good solution. It's fairly active (11 days since the last commit as of this update), WHATWG-compliant, and is used in jsdom, Angular, and Polymer.

And if you want to parse HTML for web scraping, you can use YQL¹. There is a node module for it. YQL I think would be the best solution if your HTML is from a static website, since you are relying on a service, not your own code and processing power. Though note that it won't work if the page is disallowed by the robot.txt of the website, YQL won't work with it.

If the website you're trying to scrape is dynamic then you should be using a headless browser like phantomjs. Also have a look at casperjs, if you're considering phantomjs. And you can control casperjs from node with SpookyJS.

Beside phantomjs there's zombiejs. Unlike phantomjs that cannot be embedded in nodejs, zombiejs is just a node module.

There's a nettuts+ toturial for the latter solutions.

¹ Since Aug. 2014, YUI library, which is a requirement for YQL, is no longer actively maintained, source

You are reading all rows into a list, then processing that list. Don't do that.

Process your rows as you produce them. If you need to filter the data first, use a generator function:

import csv

def getstuff(filename, criterion):
    with open(filename, "rb") as csvfile:
        datareader = csv.reader(csvfile)
        yield next(datareader)  # yield the header row
        count = 0
        for row in datareader:
            if row[3] == criterion:
                yield row
                count += 1
            elif count:
                # done when having read a consecutive series of rows 
                return

I also simplified your filter test; the logic is the same but more concise.

Because you are only matching a single sequence of rows matching the criterion, you could also use:

import csv
from itertools import dropwhile, takewhile

def getstuff(filename, criterion):
    with open(filename, "rb") as csvfile:
        datareader = csv.reader(csvfile)
        yield next(datareader)  # yield the header row
        # first row, plus any subsequent rows that match, then stop
        # reading altogether
        # Python 2: use `for row in takewhile(...): yield row` instead
        # instead of `yield from takewhile(...)`.
        yield from takewhile(
            lambda r: r[3] == criterion,
            dropwhile(lambda r: r[3] != criterion, datareader))
        return

You can now loop over getstuff() directly. Do the same in getdata():

def getdata(filename, criteria):
    for criterion in criteria:
        for row in getstuff(filename, criterion):
            yield row

Now loop directly over getdata() in your code:

for row in getdata(somefilename, sequence_of_criteria):
    # process row

You now only hold one row in memory, instead of your thousands of lines per criterion.

yield makes a function a generator function, which means it won't do any work until you start looping over it.

Open Chrome Developer Tools -> go to Network -> select Disable Cache -> reload

From command prompt Run as Administrator. Example below is to print a list of Services running on your PC run the command below:

net start > c:\netstart.txt

You should see a copy of the text file you just exported with a listing all the PC services running at the root of your C:\ drive.

It's a lot more simple that you think. You've signed into both your mobile and Chrome on your desktop using the same Google account. Google simply expect you will have your mobile with you most of the time. They take the location data from your phone and assume the location of your current desktop session is the same.

I proved this by RDPing into my Windows machine at home from work and checking Google maps remotely. It show my location as the same as Chrome on Linux at work.

If you don't have a mobile that is signed into Google then all they can do is lookup GeoIP data for the IP address assigned by your ISP. It will typically be wildly inaccurate.

Here's mine, which is very similar to Aaron Gage's, just a little more conventional, in my opinion. For my purposes, I haven't ran into any performance issues with List<T>. It would be easy enough to switch to a LinkedList if needed.

namespace Overby.Collections
{
    public class TreeNode<T>
    {
        private readonly T _value;
        private readonly List<TreeNode<T>> _children = new List<TreeNode<T>>();

        public TreeNode(T value)
        {
            _value = value;
        }

        public TreeNode<T> this[int i]
        {
            get { return _children[i]; }
        }

        public TreeNode<T> Parent { get; private set; }

        public T Value { get { return _value; } }

        public ReadOnlyCollection<TreeNode<T>> Children
        {
            get { return _children.AsReadOnly(); }
        }

        public TreeNode<T> AddChild(T value)
        {
            var node = new TreeNode<T>(value) {Parent = this};
            _children.Add(node);
            return node;
        }

        public TreeNode<T>[] AddChildren(params T[] values)
        {
            return values.Select(AddChild).ToArray();
        }

        public bool RemoveChild(TreeNode<T> node)
        {
            return _children.Remove(node);
        }

        public void Traverse(Action<T> action)
        {
            action(Value);
            foreach (var child in _children)
                child.Traverse(action);
        }

        public IEnumerable<T> Flatten()
        {
            return new[] {Value}.Concat(_children.SelectMany(x => x.Flatten()));
        }
    }
}

This one works on more than one dropdown in the same page. Furthermore, I added caret on selected item:

    $(".dropdown-menu").on('click', 'li a', function(){
        $(this).parent().parent().siblings(".btn:first-child").html($(this).text()+' <span class="caret"></span>');
        $(this).parent().parent().siblings(".btn:first-child").val($(this).text());
    });

switch(position) {
  case 0:
    ...
    break;
  case 1:
    ...
    break;
  default:
    ...

}

Did you mean that?

The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.

From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/

the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.

var wordOccurrences = words
                .GroupBy(w => w)
                .Select(intermediate => new
                {
                    Word = intermediate.Key,
                    Frequency = intermediate.Sum(w => 1)
                })
                .Where(w => w.Frequency > 10)
                .OrderBy(w => w.Frequency);

For the distributed portion, you could check out DryadLINQ: http://research.microsoft.com/en-us/projects/dryadlinq/default.aspx

If you by any chance wants to change the type of your collection you are better served with the Count() extension. This way you don't have to refactor your code (to use Length for instance).

An efficient way to loop over an Array is the built-in array method .map()

For a 1-dimensional array it would look like this:

function HandleOneElement( Cuby ) {
   Cuby.dimension
   Cuby.position_x
   ...
}
cubes.map(HandleOneElement) ; // the map function will pass each element

for 2-dimensional array:

cubes.map( function( cubeRow ) { cubeRow.map( HandleOneElement ) } )

for an n-dimensional array of any form:

Function.prototype.ArrayFunction = function(param) {
  if (param instanceof Array) {
    return param.map( Function.prototype.ArrayFunction, this ) ;
  }
  else return (this)(param) ;
}
HandleOneElement.ArrayFunction(cubes) ;

In my case I had a pem file which contained two certificates and an encrypted private key to be used in mutual SSL authentication. So my pem file looked like this:

-----BEGIN CERTIFICATE-----

...

-----END CERTIFICATE-----

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

Proc-Type: 4,ENCRYPTED

DEK-Info: DES-EDE3-CBC,C8BF220FC76AA5F9

...

-----END RSA PRIVATE KEY-----

-----BEGIN CERTIFICATE-----

...

-----END CERTIFICATE-----

Here is what I did

Split the file into three separate files, so that each one contains just one entry, starting with ---BEGIN.. and ending with ---END.. lines. Lets assume we now have three files: cert1.pem, cert2.pem, and pkey.pem.

Convert pkey.pem into DER format using openssl and the following syntax:

openssl pkcs8 -topk8 -nocrypt -in pkey.pem -inform PEM -out pkey.der -outform DER

Note, that if the private key is encrypted you need to supply a password( obtain it from the supplier of the original pem file ) to convert to DER format, openssl will ask you for the password like this: "enter a passphrase for pkey.pem: ".

If conversion is successful, you will get a new file called pkey.der.

Create a new java keystore and import the private key and the certificates:

String keypass = "password";  // this is a new password, you need to come up with to protect your java key store file
String defaultalias = "importkey";
KeyStore ks = KeyStore.getInstance("JKS", "SUN");

// this section does not make much sense to me, 
// but I will leave it intact as this is how it was in the original example I found on internet:   
ks.load( null, keypass.toCharArray());
ks.store( new FileOutputStream ( "mykeystore"  ), keypass.toCharArray());
ks.load( new FileInputStream ( "mykeystore" ),    keypass.toCharArray());
// end of section..


// read the key file from disk and create a PrivateKey

FileInputStream fis = new FileInputStream("pkey.der");
DataInputStream dis = new DataInputStream(fis);
byte[] bytes = new byte[dis.available()];
dis.readFully(bytes);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);

byte[] key = new byte[bais.available()];
KeyFactory kf = KeyFactory.getInstance("RSA");
bais.read(key, 0, bais.available());
bais.close();

PKCS8EncodedKeySpec keysp = new PKCS8EncodedKeySpec ( key );
PrivateKey ff = kf.generatePrivate (keysp);


// read the certificates from the files and load them into the key store:

Collection  col_crt1 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert1.pem"));
Collection  col_crt2 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert2.pem"));

Certificate crt1 = (Certificate) col_crt1.iterator().next();
Certificate crt2 = (Certificate) col_crt2.iterator().next();
Certificate[] chain = new Certificate[] { crt1, crt2 };

String alias1 = ((X509Certificate) crt1).getSubjectX500Principal().getName();
String alias2 = ((X509Certificate) crt2).getSubjectX500Principal().getName();

ks.setCertificateEntry(alias1, crt1);
ks.setCertificateEntry(alias2, crt2);

// store the private key
ks.setKeyEntry(defaultalias, ff, keypass.toCharArray(), chain );

// save the key store to a file         
ks.store(new FileOutputStream ( "mykeystore" ),keypass.toCharArray());

(optional) Verify the content of your new key store:

$ keytool -list -keystore mykeystore -storepass password

Keystore type: JKS Keystore provider: SUN

Your keystore contains 3 entries:

• cn=...,ou=...,o=.., Sep 2, 2014, trustedCertEntry, Certificate fingerprint (SHA1): 2C:B8: ...

• importkey, Sep 2, 2014, PrivateKeyEntry, Certificate fingerprint (SHA1): 9C:B0: ...

• cn=...,o=...., Sep 2, 2014, trustedCertEntry, Certificate fingerprint (SHA1): 83:63: ...

(optional) Test your certificates and private key from your new key store against your SSL server: ( You may want to enable debugging as an VM option: -Djavax.net.debug=all )

        char[] passw = "password".toCharArray();
        KeyStore ks = KeyStore.getInstance("JKS", "SUN");
        ks.load(new FileInputStream ( "mykeystore" ), passw );

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, passw);

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ks);
        TrustManager[] tm = tmf.getTrustManagers();

        SSLContext sclx = SSLContext.getInstance("TLS");
        sclx.init( kmf.getKeyManagers(), tm, null);

        SSLSocketFactory factory = sclx.getSocketFactory();
        SSLSocket socket = (SSLSocket) factory.createSocket( "192.168.1.111", 443 );
        socket.startHandshake();

        //if no exceptions are thrown in the startHandshake method, then everything is fine..

Finally register your certificates with HttpsURLConnection if plan to use it:

        char[] passw = "password".toCharArray();
        KeyStore ks = KeyStore.getInstance("JKS", "SUN");
        ks.load(new FileInputStream ( "mykeystore" ), passw );

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, passw);

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ks);
        TrustManager[] tm = tmf.getTrustManagers();

        SSLContext sclx = SSLContext.getInstance("TLS");
        sclx.init( kmf.getKeyManagers(), tm, null);

        HostnameVerifier hv = new HostnameVerifier()
        {
            public boolean verify(String urlHostName, SSLSession session)
            {
                if (!urlHostName.equalsIgnoreCase(session.getPeerHost()))
                {
                    System.out.println("Warning: URL host '" + urlHostName + "' is different to SSLSession host '" + session.getPeerHost() + "'.");
                }
                return true;
            }
        };

        HttpsURLConnection.setDefaultSSLSocketFactory( sclx.getSocketFactory() );
        HttpsURLConnection.setDefaultHostnameVerifier(hv);

To read a binary file to a bytes object:

from pathlib import Path
data = Path('/path/to/file').read_bytes()  # Python 3.5+

To create an int from bytes 0-3 of the data:

i = int.from_bytes(data[:4], byteorder='little', signed=False)

To unpack multiple ints from the data:

import struct
ints = struct.unpack('iiii', data[:16])

• pathlib
• int.from_bytes()
• struct

These are not command line args. Run psql. Manage to log into database (so pass the hostname, port, user and database if needed). And then write it in the psql program.

Example (below are two commands, write the first one, press enter, wait for psql to login, write the second):

In a navigation based application you can change color

NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];
if ([[ver objectAtIndex:0] intValue] >= 7) {
    self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];
    self.navigationController.navigationBar.translucent = NO;
} else {
    self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];
}

Android uses hexadecimal ARGB values, which are formatted as #AARRGGBB. That first pair of letters, the AA, represent the alpha channel. You must convert your decimal opacity values to a hexadecimal value. Here are the steps:

Alpha Hex Value Process

1. Take your opacity as a decimal value and multiply it by 255. So, if you have a block that is 50% opaque the decimal value would be .5. For example: .5 x 255 = 127.5
2. The fraction won't convert to hexadecimal, so you must round your number up or down to the nearest whole number. For example: 127.5 rounds up to 128; 55.25 rounds down to 55.
3. Enter your decimal value in a decimal-to-hexadecimal converter, like http://www.binaryhexconverter.com/decimal-to-hex-converter, and convert your values.
4. If you only get back a single value, prefix it with a zero. For example, if you're trying to get 5% opacity and you're going through this process, you'll end up with the hexadecimal value of D. Add a zero in front of it so it appears as 0D.

That's how you find the alpha channel value. I've taken the liberty to put together a list of values for you. Enjoy!

Hex Opacity Values

• 100% — FF
• 95% — F2
• 90% — E6
• 85% — D9
• 80% — CC
• 75% — BF
• 70% — B3
• 65% — A6
• 60% — 99
• 55% — 8C
• 50% — 80
• 45% — 73
• 40% — 66
• 35% — 59
• 30% — 4D
• 25% — 40
• 20% — 33
• 15% — 26
• 10% — 1A
• 5% — 0D
• 0% — 00

You can add any extension (in Wamp and Xampp servers) by removing the semi-colon (;)

You can create you own exception by inheriting from java.lang.Exception Here is an example that can help you do that.

cakephp version >= 3.6

echo $this->Form->control('field_name', ['type' => 'select', 'options' => $departments, 'default' => 'your value']);

This problem seems to arise from new versions of android sdk the solution that worked fine for me was to go to help->check for updates and let that finish once all software in eclipse updated it all seems to work fine. I was using juno and the latest sdk, which I upgraded outside eclipse.

you cannot set this in javascript, you have to do this with html/css:

<style type="text/css" media="print">
  @page { size: landscape; }
</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

An alternative for the bind() method.

Use the click() method, do something like this:

commentbtn.click({id: 10, name: "João"}, onClickCommentBtn);

function onClickCommentBtn(event)
{
  alert("Id=" + event.data.id + ", Name = " + event.data.name);
}

Or, if you prefer:

commentbtn.click({id: 10, name: "João"},  function (event) {
  alert("Id=" + event.data.id + ", Nome = " + event.data.name);
});

It will show an alert box with the following infos:

Id = 10, Name = João

One simple thing you could do is abstract the test inside a function.

local function isempty(s)
  return s == nil or s == ''
end

if isempty(foo) then
  foo = "default value"
end

android:targetSdkVersion="20" it should be < 21.

Change

For Xcode Version 8.2 (8C38), you can remove the projects completely (project name in Xcode, programs, data, etc.) one by one by doing the following: [Note: the instructions are not for just remove the project names from the Welcome Window]

Launch the Xocde and wait until the Welcome window is displayed. The projects will be shown on the right hand side (see below) Xcode Welcome Window

Right click the project you want to remove completely and a pop window [Show in Folder] jumps out; selec it to find out where is the project in the [Finder] (see below) Find the project folder

Right click the project folder in the Finder to find it’s path through [Get Info]; use path in the Info window to go to the parent folder, and go to there[Locate the project folder path] (see below)

Right click the Project Folder (e.g. DemoProject01) and Porject file (DemoProject01.xcodeproj) and select [Move to Trash] ; you will see that (a) the folder in finder is removed AND (b) the Project in the Xcode Welcome Window’s Project List is removed.

I am python novice so this may not be the most efficient method but, if I understand the intent of the question correctly, steps listed below worked for me.

>>> import numpy as np
>>> Data = np.random.random((100, 100, 1000, 2))
>>> result = np.empty(Data.shape[:-1], dtype=complex)
>>> result.real = Data[...,0]; result.imag = Data[...,1]
>>> print Data[0,0,0,0], Data[0,0,0,1], result[0,0,0]

You can also just use the top command and your user ID will indicate the jobs running and the their times.

(this will show all running jobs)

$ top -U [user ID]

(This will show jobs that are specific for the user ID)

In my case this was caused by the flexie script which was part of the "CDNJS Selections" app offered by Cloudflare.

According to Cloudflare "This app is being deprecated in March 2015". I turned it off and the message disappeared instantly.

Because by default jQuery serializes objects passed as the data parameter to $.ajax. It uses $.param to convert the data to a query string.

From the jQuery docs for $.ajax:

[the data argument] is converted to a query string, if not already a string

If you want to send JSON, you'll have to encode it yourself:

data: JSON.stringify(arr);

Note that JSON.stringify is only present in modern browsers. For legacy support, look into json2.js

Have you tried using the JQuery change event?

$("#g01-01").change(function() {
    if(this.checked) {
        //Do stuff
    }
});

Then you can also remove onchange="doalert(this.id)" from your checkbox :)

Edit:

I don't know if you are using JQuery, but if you're not yet using it, you will need to put the following script in your page so you can use it:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

You need to include the protocol scheme:

'http://192.168.1.61:8080/api/call'

Without the http:// part, requests has no idea how to connect to the remote server.

Note that the protocol scheme must be all lowercase; if your URL starts with HTTP:// for example, it won’t find the http:// connection adapter either.

Seems the SMTP as internet standard uses only reliable Transport protocol. RFC821 has TCP, NCP, NITS as examples!

If you want a popup window rather than a <div />, I would suggest the following approach.

In your parent page, you call a small helper method to show the popup window:

<input type="button" name="choice" onClick="selectValue('sku1')" value="?">

Add the following JS methods:

function selectValue(id)
{
    // open popup window and pass field id
    window.open('sku.php?id=' + encodeURIComponent(id),'popuppage',
      'width=400,toolbar=1,resizable=1,scrollbars=yes,height=400,top=100,left=100');
}

function updateValue(id, value)
{
    // this gets called from the popup window and updates the field with a new value
    document.getElementById(id).value = value;
}

Your sku.php receives the selected field via $_GET['id'] and uses it to construct the parent callback function:

?>
<script type="text/javascript">
function sendValue(value)
{
    var parentId = <?php echo json_encode($_GET['id']); ?>;
    window.opener.updateValue(parentId, value);
    window.close();
}
</script>

For each row in your popup, change code to this:

<td><input type=button value="Select" onClick="sendValue('<?php echo $rows['packcode']; ?>')" /></td>

Following this approach, the popup window doesn't need to know how to update fields in the parent form.

As you are referring to a combobox, I'm assuming you don't want to use 2-way databinding (if so, look at using a BindingList)

public class Country
{
    public string Name { get; set; }
    public IList<City> Cities { get; set; }
    public Country(string _name)
    {
        Cities = new List<City>();
        Name = _name;
    }
}

List<Country> countries = new List<Country> { new Country("UK"), 
                                     new Country("Australia"), 
                                     new Country("France") };

var bindingSource1 = new BindingSource();
bindingSource1.DataSource = countries;

comboBox1.DataSource = bindingSource1.DataSource;

comboBox1.DisplayMember = "Name";
comboBox1.ValueMember = "Name";

To find the country selected in the bound combobox, you would do something like: Country country = (Country)comboBox1.SelectedItem;.

If you want the ComboBox to dynamically update you'll need to make sure that the data structure that you have set as the DataSource implements IBindingList; one such structure is BindingList<T>.

Tip: make sure that you are binding the DisplayMember to a Property on the class and not a public field. If you class uses public string Name { get; set; } it will work but if it uses public string Name; it will not be able to access the value and instead will display the object type for each line in the combo box.

Since Java 7 you can use the relativize method:

import java.nio.file.Path;
import java.nio.file.Paths;

public class Test {

     public static void main(String[] args) {
        Path pathAbsolute = Paths.get("/var/data/stuff/xyz.dat");
        Path pathBase = Paths.get("/var/data");
        Path pathRelative = pathBase.relativize(pathAbsolute);
        System.out.println(pathRelative);
    }

}

Output:

stuff/xyz.dat

Change your foreach to something like this, You are not assigning data back to your return variable $data after performing operation on that.

foreach($data as $key => $value)
{
  $data[$key]['transaction_date'] = date('d/m/Y',$value['transaction_date']);
}

Codepad DEMO.

I have developed this functionality from one Blog. There are 2 ways you can send SMS.

1. Open native SMS composer
2. write your message and send from your Android application

This is the code of 1st method.

Main.xml

<?xml version="1.0" encoding="utf-8"?>  
    <RelativeLayout  
        android:id="@+id/relativeLayout1"  
        android:layout_width="fill_parent"  
        android:layout_height="fill_parent"  
        xmlns:android="http://schemas.android.com/apk/res/android">  

            <Button  
                android:id="@+id/btnSendSMS"  
               android:layout_height="wrap_content"  
               android:layout_width="wrap_content"  
               android:text="Send SMS"  
               android:layout_centerInParent="true"  
               android:onClick="sendSMS">  
           </Button>  
   </RelativeLayout>

Activity

public class SendSMSActivity extends Activity {  
     /** Called when the activity is first created. */  
     @Override  
     public void onCreate(Bundle savedInstanceState) {  
         super.onCreate(savedInstanceState);  
         setContentView(R.layout.main);  
      }  

     public void sendSMS(View v)  
     {  
         String number = "12346556";  // The number on which you want to send SMS  
         startActivity(new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", number, null)));  
     }  
    /* or 
     public void sendSMS(View v) 
      { 
     Uri uri = Uri.parse("smsto:12346556"); 
         Intent it = new Intent(Intent.ACTION_SENDTO, uri); 
         it.putExtra("sms_body", "Here you can set the SMS text to be sent"); 
         startActivity(it); 
      } */  
 }

NOTE:- In this method, you don’t require SEND_SMS permission inside the AndroidManifest.xml file.

For 2nd method refer to this BLOG. You will find a good explanation from here.

Hope this will help you...

You can also create an associative array, or a "hash-table" like array, by specifying the index of the array.

$array = array(
    0 => array(
        'name' => 'John Doe',
        'email' => '[email protected]'
    ),
    1 => array(
        'name' => 'Jane Doe',
        'email' => '[email protected]'
    ),
);

Which is equivalent to

$array = array();

$array[0] = array();
$array[0]['name'] = 'John Doe';
$array[0]['email'] = '[email protected]';

$array[1] = array();
$array[1]['name'] = 'Jane Doe';
$array[1]['email'] = '[email protected]';

There is a good explanation at https://stackoverflow.com/a/33833319/903783

The values expected seem to be xlCopy and xlCut according to xlCutCopyMode enumeration (https://msdn.microsoft.com/en-us/VBA/Excel-VBA/articles/xlcutcopymode-enumeration-excel), but the 0 value (this is what False equals to in VBA) seems to be useful to clear Excel data put on the Clipboard.

UPDATE: As of Bootstrap 3.0, the input-* classes described below for setting the width of input elements were removed. Instead use the col-* classes to set the width of input elements. Examples are provided in the documentation.

In Bootstrap 2.3, you'd use the input classes for setting the width.

<textarea class="input-mini"></textarea>
<textarea class="input-small"></textarea>
<textarea class="input-medium"></textarea>
<textarea class="input-large"></textarea>
<textarea class="input-xlarge"></textarea>
<textarea class="input-xxlarge"></textarea>?
<textarea class="input-block-level"></textarea>?

Do a find for "Control sizing" for examples in the documentation.

But for height I think you'd still use the rows attribute.

Struct values encode as JSON objects. Each exported struct field becomes a member of the object unless:

• the field's tag is "-", or
• the field is empty and its tag specifies the "omitempty" option.

The empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. The object's default key string is the struct field name but can be specified in the struct field's tag value. The "json" key in the struct field's tag value is the key name, followed by an optional comma and options.

if you embed the pdf in your webpage and reference the object id, you should be able to do it.

eg. in your HTML:

<object ID="examplePDF" type="application/pdf" data="example.pdf" width="500" height="500">

in your javascript:

<script>

var pdf = document.getElementById("examplePDF");

pdf.print();

</script>

I hope that helps.

Here is the solution.

The HTML:

<div class="rating">
<span>?</span><span>?</span><span>?</span><span>?</span><span>?</span>
</div>

The CSS:

.rating {
  unicode-bidi: bidi-override;
  direction: rtl;
}
.rating > span {
  display: inline-block;
  position: relative;
  width: 1.1em;
}
.rating > span:hover:before,
.rating > span:hover ~ span:before {
   content: "\2605";
   position: absolute;
}

Hope this helps.

I got the same same error.

I was using gmail account and Google's SMTP server to send emails. The problem was due to SMTP server refusing to authorize as it considered my web host (through whom I sent email) as an intruder.

I followed Google's process to identify my web host as an valid entity to send email through my account and problem was solved.

The only way you should be getting values "out of" an Observable/Subject is with subscribe!

If you're using getValue() you're doing something imperative in declarative paradigm. It's there as an escape hatch, but 99.9% of the time you should NOT use getValue(). There are a few interesting things that getValue() will do: It will throw an error if the subject has been unsubscribed, it will prevent you from getting a value if the subject is dead because it's errored, etc. But, again, it's there as an escape hatch for rare circumstances.

There are several ways of getting the latest value from a Subject or Observable in a "Rx-y" way:

1. Using BehaviorSubject: But actually subscribing to it. When you first subscribe to BehaviorSubject it will synchronously send the previous value it received or was initialized with.
2. Using a ReplaySubject(N): This will cache N values and replay them to new subscribers.
3. A.withLatestFrom(B): Use this operator to get the most recent value from observable B when observable A emits. Will give you both values in an array [a, b].
4. A.combineLatest(B): Use this operator to get the most recent values from A and B every time either A or B emits. Will give you both values in an array.
5. shareReplay(): Makes an Observable multicast through a ReplaySubject, but allows you to retry the observable on error. (Basically it gives you that promise-y caching behavior).
6. publishReplay(), publishBehavior(initialValue), multicast(subject: BehaviorSubject | ReplaySubject), etc: Other operators that leverage BehaviorSubject and ReplaySubject. Different flavors of the same thing, they basically multicast the source observable by funneling all notifications through a subject. You need to call connect() to subscribe to the source with the subject.

If you're using ZLib in your project, then you need to find :

#if 1

in zconf.h and replace(uncomment) it with :

#if HAVE_UNISTD_H /* ...the rest of the line

If it isn't ZLib I guess you should find some alternative way to do this. GL.

Most windows users won't have that font on their computers. Also, you can't just submit it to your server and call it using font-face because this isn't a free font...

And last, but not least, answering the question that nobody mentioned yet, Helvetica and Helvetica Neue do not render well on screen unless they have a really big font-size. You'll find a lot of pages using this font, and in all of them you'll see that the top border of a line of text looks wavy and that some letters look taller than others. In my opinion this is the main reason why you shouldn't use it. There are other options for you to use, like Open Sans.

I do like this: cp /dev/null file

You need to add your macOS user name to the _developer group. See the posts in this thread for more information. The following command should do the trick:

sudo dscl . append /Groups/_developer GroupMembership <username>

For me this was the fact that debug.writeline shows in the Immediate window, not the Output. My installation of VS2013 by default doesn't even show an option to open the Immediate window, so you have to do the following:

Select Tools -> Customize 
Commands Tab
View | Other Windows menu bar dropdown
Add Command...
The Immediate option is in the Debug section.

Once you have Ok'd that, you can go to View -> Other Windows and select the Immediate Window and hey presto all of the debug output can be seen.

Unfortunately for me it also showed about 50 errors that I wasn't aware of in my project... maybe I'll just turn it off again :-)

Your code is correct. Just test to ensure it is being called like:

<script>
function doIt(){
  alert("here i am!");
  __doPostBack('ctl00$ctl00$bLogout','')
}
</script>

<iframe onload="doIt()"></iframe>

if you want to hold the arguments from Terminal, try the following code:

A = ARGV[0].to_i
B = ARGV[1].to_i

puts "#{A} + #{B} = #{A + B}"

It should be in %USERNAME%. Obviously this can be easily spoofed, so don't rely on it for security.

Useful tip: type set in a command prompt will list all environment variables.

I would just query for the for attribute instead of repetitively recursing the DOM tree.

$("input:checkbox").on("change", function() {
    $("label[for='"+this.id+"']").text("TESTTTT");
});

You could try this

def find(ch,string1):
    for i in range(len(string1)):
        if ch == string1[i]:
            pos.append(i)        

the answer by @dombenoit works. Though it introduces some code to maintain. Check this syntax out:

using (var nav = Html.Bootstrap().Begin(new Nav().Style(NavType.NavBar).SetLinksActiveByControllerAndAction()))
{
    @nav.ActionLink("Link 1", "action1")
    @nav.ActionLink("Link 2", "action2")
    @nav.Link("External Link", "#")
}

Notice the use of .SetLinksActiveByControllerAndAction() method.

If you wonder what makes this syntax possible, check out TwitterBootstrapMVC

Just an addition to what others have given, even though they work well but in some cases if internet is slow or some unknown network problem exists, some of the codes won't work (isReachable()). But this code mentioned below creates a process which acts as a command line ping (cmd ping) to windows. It works for me in all cases, tried and tested.

Code :-

public class JavaPingApp {

public static void runSystemCommand(String command) {

    try {
        Process p = Runtime.getRuntime().exec(command);
        BufferedReader inputStream = new BufferedReader(
                new InputStreamReader(p.getInputStream()));

        String s = "";
        // reading output stream of the command
        while ((s = inputStream.readLine()) != null) {
            System.out.println(s);
        }

    } catch (Exception e) {
        e.printStackTrace();
    }
}

public static void main(String[] args) {

    String ip = "stackoverflow.com"; //Any IP Address on your network / Web
    runSystemCommand("ping " + ip);
}
}

Hope it helps, Cheers!!!

I had the same issue. Please follow these steps:

1. Make sure you have installed System.Data.SQLite.Core package by SQLite Development Team from NuGet.
2. Go to project solution and try to locate build folder inside packages folder
3. Check your project framework and pick the desired SQLite.Interop.dll and place it in your debug/release folder

This assumes that the first row of the csv is the headers

import csv

# open the file in universal line ending mode 
with open('test.csv', 'rU') as infile:
  # read the file as a dictionary for each row ({header : value})
  reader = csv.DictReader(infile)
  data = {}
  for row in reader:
    for header, value in row.items():
      try:
        data[header].append(value)
      except KeyError:
        data[header] = [value]

# extract the variables you want
names = data['name']
latitude = data['latitude']
longitude = data['longitude']

Those are varargs they are used to create a method that receive any number of arguments.

For instance PrintStream.printf method uses it, since you don't know how many would arguments you'll use.

They can only be used as final position of the arguments.

varargs was was added on Java 1.5

I was in a situation where Linq binding was not available and had to expand lambda explicitly. It resulted in a simple function:

public static T KeyByValue<T, W>(this Dictionary<T, W> dict, W val)
{
    T key = default;
    foreach (KeyValuePair<T, W> pair in dict)
    {
        if (EqualityComparer<W>.Default.Equals(pair.Value, val))
        {
            key = pair.Key;
            break;
        }
    }
    return key;
}

Call it like follows:

public static void Main()
{
    Dictionary<string, string> dict = new Dictionary<string, string>()
    {
        {"1", "one"},
        {"2", "two"},
        {"3", "three"}
    };

    string key = KeyByValue(dict, "two");       
    Console.WriteLine("Key: " + key);
}

Works on .NET 2.0 and in other limited environments.

Very Easy solution , change colorPrimary as your choice and it will change color of button text of alert box.

<style name="MyAlertDialogStyle" parent="android:Theme.Material.Dialog.Alert">


        <!-- Used for the buttons -->
        <item name="colorAccent">@android:color/white</item>
        <!-- Used for the title and text -->
        <item name="android:textColorPrimary">@color/black</item>

        <!-- Used for the background -->
        <item name="android:background">#ffffff</item>
        <item name="android:colorPrimary">@color/white</item>
        <item name="android:colorAccent">@color/white</item>
        <item name="android:windowEnterAnimation">@anim/bottom_left_enter</item>
    </style>

Alternative (Using Java)

 @SuppressLint("ResourceAsColor")

A year has 52 weeks and 1 day or 2 in case of a lap year (52 x 7 = 364). 2012-12-31 would be week 53, a week that would only have 2 days because 2012 is a lap year.

To set the placeholder color once for all the UITextField in your app you can do:

UILabel.appearanceWhenContainedInInstancesOfClasses([UITextField.self]).textColor = UIColor.redColor()

This will set the desired color for all TextField placeholders in the entire app. But it is only available since iOS 9.

There is no appearenceWhenContainedIn....() method before iOS 9 in swift but you can use one of the solutions provided here appearanceWhenContainedIn in Swift

if by .add you mean .append, then the result is the same if #myDiv is empty.

is the performance the same? dont know.

.html(x) ends up doing the same thing as .empty().append(x)

Also note that using the "foreach" method in the original question does have some limitations, such as not being able to remove items from the list during the iteration.

The new for-loop is easier to read and removes the need for a separate iterator, but is only really usable in read-only iteration passes.

The location of jfxrt.jar in Oracle Java 7 is:

<JRE_HOME>/lib/jfxrt.jar

The location of jfxrt.jar in Oracle Java 8 is:

<JRE_HOME>/lib/ext/jfxrt.jar

The <JRE_HOME> will depend on where you installed the Oracle Java and may differ between Linux distributions and installations.

jfxrt.jar is not in the Linux OpenJDK 7 (which is what you are using).

An open source package which provides JavaFX 8 for Debian based systems such as Ubuntu is available. To install this package it is necessary to install both the Debian OpenJDK 8 package and the Debian OpenJFX package. I don't run Debian, so I'm not sure where the Debian OpenJFX package installs jfxrt.jar.

Use Oracle Java 8.

With Oracle Java 8, JavaFX is both included in the JDK and is on the default classpath. This means that JavaFX classes will automatically be found both by the compiler during the build and by the runtime when your users use your application. So using Oracle Java 8 is currently the best solution to your issue.

OpenJDK for Java 8 could include JavaFX (as JavaFX for Java 8 is now open source), but it will depend on the OpenJDK package assemblers as to whether they choose to include JavaFX 8 with their distributions. I hope they do, as it should help remove the confusion you experienced in your question and it also provides a great deal more functionality in OpenJDK.

My understanding is that although JavaFX has been included with the standard JDK since version JDK 7u6

Yes, but only the Oracle JDK.

The JavaFX version bundled with Java 7 was not completely open source so it could not be included in the OpenJDK (which is what you are using).

In you need to use Java 7 instead of Java 8, you could download the Oracle JDK for Java 7 and use that. Then JavaFX will be included with Java 7. Due to the way Oracle configured Java 7, JavaFX won't be on the classpath. If you use Java 7, you will need to add it to your classpath and use appropriate JavaFX packaging tools to allow your users to run your application. Some tools such as e(fx)clipse and NetBeans JavaFX project type will take care of classpath issues and packaging tasks for you.

I solved my problem killing all tracker-control processes (you could try if you use GDM, obviously not your case if the script is running on a server)

tracker-control -r

My setup: Arch with GNOME 3

I had a similar issue which i solved by making two changes

1. added below entry in application.yaml file

   spring: jackson: serialization.write_dates_as_timestamps: false

2. add below two annotations in pojo

   1. @JsonDeserialize(using = LocalDateDeserializer.class)
   2. @JsonSerialize(using = LocalDateSerializer.class)

   sample example

   import com.fasterxml.jackson.databind.annotation.JsonDeserialize; import com.fasterxml.jackson.databind.annotation.JsonSerialize; public class Customer { //your fields ... @JsonDeserialize(using = LocalDateDeserializer.class) @JsonSerialize(using = LocalDateSerializer.class) protected LocalDate birthdate; }

then the following json requests worked for me

1. sample request format as string

{ "birthdate": "2019-11-28" }

2. sample request format as array

{ "birthdate":[2019,11,18] }

Hope it helps!!

There is no need to compute trigonometric functions. The simple code in C language is:

#include <math.h>
#define PIV2 M_PI+M_PI
#define C360 360.0000000000000000000
double difangrad(double x, double y)
{
double arg;

arg = fmod(y-x, PIV2);
if (arg < 0 )  arg  = arg + PIV2;
if (arg > M_PI) arg  = arg - PIV2;

return (-arg);
}
double difangdeg(double x, double y)
{
double arg;
arg = fmod(y-x, C360);
if (arg < 0 )  arg  = arg + C360;
if (arg > 180) arg  = arg - C360;
return (-arg);
}

let dif = a - b , in radians

dif = difangrad(a,b);

let dif = a - b , in degrees

dif = difangdeg(a,b);

difangdeg(180.000000 , -180.000000) = 0.000000
difangdeg(-180.000000 , 180.000000) = -0.000000
difangdeg(359.000000 , 1.000000) = -2.000000
difangdeg(1.000000 , 359.000000) = 2.000000

No sin, no cos, no tan,.... only geometry!!!!

yo can extend your JS with a select method like this

Array.prototype.select = function(closure){
    for(var n = 0; n < this.length; n++) {
        if(closure(this[n])){
            return this[n];
        }
    }

    return null;
};

now you can use this:

var x = [1,2,3,4];

var a = x.select(function(v) {
    return v == 2;
});

console.log(a);

or for objects in a array

var x = [{id: 1, a: true},
    {id: 2, a: true},
    {id: 3, a: true},
    {id: 4, a: true}];

var a = x.select(function(obj) {
    return obj.id = 2;
});

console.log(a);

The following will work for a DateTime that has fractional milliseconds, and also preserves the Kind property (Local, Utc or Undefined).

DateTime dateTime = ... anything ...
dateTime = new DateTime(
    dateTime.Ticks - (dateTime.Ticks % TimeSpan.TicksPerSecond), 
    dateTime.Kind
    );

or the equivalent and shorter:

dateTime = dateTime.AddTicks( - (dateTime.Ticks % TimeSpan.TicksPerSecond));

This could be generalized into an extension method:

public static DateTime Truncate(this DateTime dateTime, TimeSpan timeSpan)
{
    if (timeSpan == TimeSpan.Zero) return dateTime; // Or could throw an ArgumentException
    if (dateTime == DateTime.MinValue || dateTime == DateTime.MaxValue) return dateTime; // do not modify "guard" values
    return dateTime.AddTicks(-(dateTime.Ticks % timeSpan.Ticks));
}

which is used as follows:

dateTime = dateTime.Truncate(TimeSpan.FromMilliseconds(1)); // Truncate to whole ms
dateTime = dateTime.Truncate(TimeSpan.FromSeconds(1)); // Truncate to whole second
dateTime = dateTime.Truncate(TimeSpan.FromMinutes(1)); // Truncate to whole minute
...

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)
