You can always use one of the typeOf functions on JavaScript blogs such as Chris West's. Using a definition such as the following for the typeOf() function would work:

function typeOf(o){return {}.toString.call(o).slice(8,-1)}

This function (which is declared in the global namespace, can be used like this:

alert("onsubmit is a " + typeOf(elem.onsubmit));

If it is a function, "Function" will be returned. If it is a string, "String" will be returned. Other possible values are shown here.

In your doSomething() function, pass in the event e and use e.preventDefault().

doSomething = function (e) {
    alert('it works!');
    e.preventDefault();
}

This work around will fix the issue found by @Cletus.

function submitForm(form) {
    //get the form element's document to create the input control with
    //(this way will work across windows in IE8)
    var button = form.ownerDocument.createElement('input');
    //make sure it can't be seen/disrupts layout (even momentarily)
    button.style.display = 'none';
    //make it such that it will invoke submit if clicked
    button.type = 'submit';
    //append it and click it
    form.appendChild(button).click();
    //if it was prevented, make sure we don't get a build up of buttons
    form.removeChild(button);
}

Will work on all modern browsers.
Will work across tabs/spawned child windows (yes, even in IE<9).
And is in vanilla!

Just pass it a DOM reference to a form element and it'll make sure all the attached listeners, the onsubmit, and (if its not prevented by then) finally, submit the form.

You should stop the submit procedure by returning false on the onsubmit callback.

<script>
    function checkRegistration(){
        if(!form_valid){
            alert('Given data is not correct');
            return false;
        }
        return true;
    }
</script>

<form onsubmit="return checkRegistration()"...

Here you have a fully working example. The form will submit only when you write google into input, otherwise it will return an error:

<script>
    function checkRegistration(){
        var form_valid = (document.getElementById('some_input').value == 'google');
        if(!form_valid){
            alert('Given data is incorrect');
            return false;
        }
        return true;
    }
</script>

<form onsubmit="return checkRegistration()" method="get" action="http://google.com">
    Write google to go to google...<br/>
    <input type="text" id="some_input" value=""/>
    <input type="submit" value="google it"/>
</form>

I'm using Webmin because its a productivity gem for someone who finds command line administration a bit daunting and impenetrable.

There is a "Save and Run Now" button in the "System > Scheduled Cron Jobs > Edit Cron Job" web interface.

It displays the output of the command and is exactly what I needed.

async   : false,

By default, all requests are sent asynchronously (i.e. this is set to true by default). If you need synchronous requests, set this option to false. Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation. Note that synchronous requests may temporarily lock the browser, disabling any actions while the request is active. As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done() or the deprecated jqXHR.success().

It tells taskkill that the next parameter something.exe is an image name, a.k.a executable name

C:\>taskkill /?

TASKKILL [/S system [/U username [/P [password]]]]
         { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]

Description:
    This tool is used to terminate tasks by process id (PID) or image name.

Parameter List:
    /S    system           Specifies the remote system to connect to.

    /U    [domain\]user    Specifies the user context under which the
                           command should execute.

    /P    [password]       Specifies the password for the given user
                           context. Prompts for input if omitted.

    /FI   filter           Applies a filter to select a set of tasks.
                           Allows "*" to be used. ex. imagename eq acme*

    /PID  processid        Specifies the PID of the process to be terminated.
                           Use TaskList to get the PID.

    /IM   imagename        Specifies the image name of the process
                           to be terminated. Wildcard '*' can be used
                           to specify all tasks or image names.

    /T                     Terminates the specified process and any
                           child processes which were started by it.

    /F                     Specifies to forcefully terminate the process(es).

    /?                     Displays this help message.

In opposite to the most comments, I think it is possible to get the client's hostname (machine name) in plain PHP, but it's a little bit "dirty".

By requesting "NTLM" authorization via HTTP header...

if (!isset($headers['AUTHORIZATION']) || substr($headers['AUTHORIZATION'],0,4) !== 'NTLM'){
    header('HTTP/1.1 401 Unauthorized');
    header('WWW-Authenticate: NTLM');
    exit;
}

You can force the client to send authorization credentials via NTLM format. The NTLM hash sent by the client to server contains, besides the login credtials, the clients machine name. This works cross-browser and PHP only.

$auth = $headers['AUTHORIZATION'];

if (substr($auth,0,5) == 'NTLM ') {
    $msg = base64_decode(substr($auth, 5));
    if (substr($msg, 0, 8) != "NTLMSSPx00")
            die('error header not recognised');

    if ($msg[8] == "x01") {
            $msg2 = "NTLMSSPx00x02"."x00x00x00x00".
                    "x00x00x00x00".
                    "x01x02x81x01".
                    "x00x00x00x00x00x00x00x00".
                    "x00x00x00x00x00x00x00x00".
                    "x00x00x00x00x30x00x00x00";

            header('HTTP/1.1 401 Unauthorized');
            header('WWW-Authenticate: NTLM '.trim(base64_encode($msg2)));
            exit;
    }
    else if ($msg[8] == "x03") {
            function get_msg_str($msg, $start, $unicode = true) {
                    $len = (ord($msg[$start+1]) * 256) + ord($msg[$start]);
                    $off = (ord($msg[$start+5]) * 256) + ord($msg[$start+4]);
                    if ($unicode)
                            return str_replace("\0", '', substr($msg, $off, $len));
                    else
                            return substr($msg, $off, $len);
            }
            $user = get_msg_str($msg, 36);
            $domain = get_msg_str($msg, 28);
            $workstation = get_msg_str($msg, 44);
            print "You are $user from $workstation.$domain";
    }
}

And yes, it's not a plain and easy "read the machine name function", because the user is prompted with an dialog, but it's an example, that it is indeed possible (against the other statements here).

Full code can be found here: https://en.code-bude.net/2017/05/07/how-to-read-client-hostname-in-php/

In ES6, you can do like this.

var key = "name";
var person = {[key]:"John"}; // same as var person = {"name" : "John"}
console.log(person); // should print  Object { name="John"}

    var key = "name";_x000D_
    var person = {[key]:"John"};_x000D_
    console.log(person); // should print  Object { name="John"}

Its called Computed Property Names, its implemented using bracket notation( square brackets) []

Example: { [variableName] : someValue }

Starting with ECMAScript 2015, the object initializer syntax also supports computed property names. That allows you to put an expression in brackets [], that will be computed and used as the property name.

For ES5, try something like this

var yourObject = {};

yourObject[yourKey] = "yourValue";

console.log(yourObject );

example:

var person = {};
var key = "name";

person[key] /* this is same as person.name */ = "John";

console.log(person); // should print  Object { name="John"}

    var person = {};_x000D_
    var key = "name";_x000D_
    _x000D_
    person[key] /* this is same as person.name */ = "John";_x000D_
    _x000D_
    console.log(person); // should print  Object { name="John"}

tl;dr: baz() { this.foo(); this.bar() }

In ES2015 this construct:

var obj = {
    foo() { console.log('foo') }
}

is equal to this ES5 code:

var obj = {
    foo : function foo() { console.log('foo') }
}

exports.default = {} is like creating an object, your default export translates to ES5 code like this:

exports['default'] = {
    foo: function foo() {
        console.log('foo');
    },
    bar: function bar() {
        console.log('bar');
    },
    baz: function baz() {
        foo();bar();
    }
};

now it's kind of obvious (I hope) that baz tries to call foo and bar defined somewhere in the outer scope, which are undefined. But this.foo and this.bar will resolve to the keys defined in exports['default'] object. So the default export referencing its own methods shold look like this:

export default {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { this.foo(); this.bar() }
}

See babel repl transpiled code.

For me this solution works perfectly fine...

Including javascript files inside javascript files

In short you can load the script file with AJAX or put a script tag on the HTML to include it( before the script that uses the functions of the other script). The link I posted is a great answer and has multiple examples and explanations of both methods.

Go to file Global.asax.cs in your project and add the following code.

    protected void Application_BeginRequest()
    {
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.Now.AddHours(-1));
        Response.Cache.SetNoStore();
    }

It worked for me..! Reference link Clear session on Logout MVC 4

use css property style="display:none" or style=visibility:hidden"

Just divide the number of td to 100%. Example, you have 4 td's:

<html>
<table>
<tr>
<td style="width:25%">This is a text</td>
<td style="width:25%">This is some text, this is some text</td>
<td style="width:25%">This is another text, this is another text</td>
<td style="width:25%">This is the last text, this is the last text</td>
</tr>
</table>
</html>

We use 25% in each td to maximize the 100% space of the entire table

Not sure if it's just me, but using .remove() doesn't seem to work if you are selecting by an id.

Ex: $("#my-element").remove();

I had to use the element's class instead, or nothing happened.

The following bit of code does what you ask for. Just make sure that you assign enough space so that the text on the button becomes visible

JFrame frame = new JFrame("test");
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
JPanel panel = new JPanel(new GridLayout(4,4,4,4));

for(int i=0 ; i<16 ; i++){
    JButton btn = new JButton(String.valueOf(i));
    btn.setPreferredSize(new Dimension(40, 40));
    panel.add(btn);
}
frame.setContentPane(panel);
frame.pack();
frame.setVisible(true);

The X and Y (two first parameters of the GridLayout constructor) specify the number of rows and columns in the grid (respectively). You may leave one of them as 0 if you want that value to be unbounded.

Edit

I've modified the provided code and I believe it now conforms to what is desired:

JFrame frame = new JFrame("Colored Trails");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JPanel mainPanel = new JPanel();
mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));

JPanel firstPanel = new JPanel();
firstPanel.setLayout(new GridLayout(4, 4));
firstPanel.setMaximumSize(new Dimension(400, 400));
JButton btn;
for (int i=1; i<=4; i++) {
    for (int j=1; j<=4; j++) {
        btn = new JButton();
        btn.setPreferredSize(new Dimension(100, 100));
        firstPanel.add(btn);
    }
}

JPanel secondPanel = new JPanel();
secondPanel.setLayout(new GridLayout(5, 13));
secondPanel.setMaximumSize(new Dimension(520, 200));
for (int i=1; i<=5; i++) {
    for (int j=1; j<=13; j++) {
        btn = new JButton();
        btn.setPreferredSize(new Dimension(40, 40));
        secondPanel.add(btn);
    }
}

mainPanel.add(firstPanel);
mainPanel.add(secondPanel);
frame.setContentPane(mainPanel);

frame.setSize(520,600);
frame.setMinimumSize(new Dimension(520,600));
frame.setVisible(true);

Basically I now set the preferred size of the panels and a minimum size for the frame.

tab completion with zsh...

a date is independant of any timezone, so use a Dateformatter and attach a timezone for display:

swift:

let date = NSDate()
let dateFormatter = NSDateFormatter()
let timeZone = NSTimeZone(name: "UTC")

dateFormatter.timeZone = timeZone

println(dateFormatter.stringFromDate(date))

objC:

NSDate *date = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];

[dateFormatter setTimeStyle:NSDateFormatterMediumStyle];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
[dateFormatter setTimeZone:timeZone];       
NSLog(@"%@", [dateFormatter stringFromDate:date]);

Wrap the child you want centered in a View and make the View absolute.

<View style={{position: 'absolute', top: 0, left: 0, right: 0, bottom: 0, justifyContent: 'center', alignItems: 'center'}}>
  <Text>Centered text</Text>
</View>

It means to group by the first column regardless of what it's called. You can do the same with ORDER BY.

You can add a random (or datetime string) as query string to the url that points to your script. Like so:

<script type="text/javascript" src="test.js?q=123"></script> 

Every time you refresh the page you need to make sure the value of 'q' is changed.

In PostgreSQL 9.2 and above, to disconnect everything except your session from the database you are connected to:

SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE datname = current_database()
  AND pid <> pg_backend_pid();

In older versions it's the same, just change pid to procpid. To disconnect from a different database just change current_database() to the name of the database you want to disconnect users from.

You may want to REVOKE the CONNECT right from users of the database before disconnecting users, otherwise users will just keep on reconnecting and you'll never get the chance to drop the DB. See this comment and the question it's associated with, How do I detach all other users from the database.

If you just want to disconnect idle users, see this question.

python now points to python3, if you need python 2 then do: brew install python@2 and then in your .zshrc or .bashrc file export PATH="/usr/local/opt/python@2/libexec/bin:$PATH" Now, pyhon --version = Python 2.7.14 and python3 --version = Python 3.6.4. That's the behavior I'm used to seeing in my terminal.

If you are trying to get the drawable from the view where the image is set as,

ivshowing.setBackgroundResource(R.drawable.one);

then the drawable will return only null value with the following code...

   Drawable drawable = (Drawable) ivshowing.getDrawable();

So, it's better to set the image with the following code, if you wanna retrieve the drawable from a particular view.

 ivshowing.setImageResource(R.drawable.one);

only then the drawable will we converted exactly.

Command-line SVN

You need to add your files to your working copy, before you commit your changes to the repository:

svn add <file|folder>

Afterwards:

svn commit

See here for detailed information about svn add.

TortoiseSVN

It works with TortoiseSVN, because it adds the file to your working copy automatically (commit dialog):

If you want to include an unversioned file, just check that file to add it to the commit.

See: TortoiseSVN: Committing Your Changes To The Repository

Since String IS-A CharSequence, you can pass a String wherever you need a CharSequence, or assign a String to a CharSequence:

CharSequence cs = "string";
String s = cs.toString();
foo(s); // prints "string"

public void foo(CharSequence cs) { 
  System.out.println(cs);
}

If you want to convert a CharSequence to a String, just use the toString method that must be implemented by every concrete implementation of CharSequence.

Hope it helps.

I think this is what you want:

/grand/parent/child[@id="#grand"]

I want share my experience. A few days ago I have to update 21 million records in table with 76 million records. My colleague suggested the next variant. For example, we have the next table 'Persons':

Id | FirstName | LastName | Email            | JobTitle
1  | John      |  Doe     | [email protected]     | Software Developer
2  | John1     |  Doe1    | [email protected]     | Software Developer
3  | John2     |  Doe2    | [email protected]     | Web Designer

Task: Update persons to the new Job Title: 'Software Developer' -> 'Web Developer'.

1. Create Temporary Table 'Persons_SoftwareDeveloper_To_WebDeveloper (Id INT Primary Key)'

2. Select into temporary table persons which you want to update with the new Job Title:

INSERT INTO Persons_SoftwareDeveloper_To_WebDeveloper SELECT Id FROM
Persons WITH(NOLOCK) --avoid lock 
WHERE JobTitle = 'Software Developer' 
OPTION(MAXDOP 1) -- use only one core

Depends on rows count, this statement will take some time to fill your temporary table, but it would avoid locks. In my situation it took about 5 minutes (21 million rows).

3. The main idea is to generate micro sql statements to update database. So, let's print them:

DECLARE @i INT, @pagesize INT, @totalPersons INT
    SET @i=0
    SET @pagesize=2000
    SELECT @totalPersons = MAX(Id) FROM Persons

    while @i<= @totalPersons
    begin
    Print '
    UPDATE persons 
      SET persons.JobTitle = ''ASP.NET Developer''
      FROM  Persons_SoftwareDeveloper_To_WebDeveloper tmp
      JOIN Persons persons ON tmp.Id = persons.Id
      where persons.Id between '+cast(@i as varchar(20)) +' and '+cast(@i+@pagesize as varchar(20)) +' 
        PRINT ''Page ' + cast((@i / @pageSize) as varchar(20))  + ' of ' + cast(@totalPersons/@pageSize as varchar(20))+'
     GO
     '
     set @i=@i+@pagesize
    end

After executing this script you will receive hundreds of batches which you can execute in one tab of MS SQL Management Studio.

4. Run printed sql statements and check for locks on table. You always can stop process and play with @pageSize to speed up or speed down updating(don't forget to change @i after you pause script).

5. Drop Persons_SoftwareDeveloper_To_AspNetDeveloper. Remove temporary table.

Minor Note: This migration could take a time and new rows with invalid data could be inserted during migration. So, firstly fix places where your rows adds. In my situation I fixed UI, 'Software Developer' -> 'Web Developer'.

I hope following program will solve your problem

String dateStr = "Mon Jun 18 00:00:00 IST 2012";
DateFormat formatter = new SimpleDateFormat("E MMM dd HH:mm:ss Z yyyy");
Date date = (Date)formatter.parse(dateStr);
System.out.println(date);        

Calendar cal = Calendar.getInstance();
cal.setTime(date);
String formatedDate = cal.get(Calendar.DATE) + "/" + (cal.get(Calendar.MONTH) + 1) + "/" +         cal.get(Calendar.YEAR);
System.out.println("formatedDate : " + formatedDate);    

The error you are getting is either because you are doing TO_DATE on a column that's already a date, and you're using a format mask that is different to your nls_date_format parameter[1] or because the event_occurrence column contains data that isn't a number.

You need to a) correct your query so that it's not using TO_DATE on the date column, and b) correct your data, if event_occurrence is supposed to be just numbers.

And fix the datatype of that column to make sure you can only store numbers.

[1] What Oracle does when you do: TO_DATE(date_column, non_default_format_mask) is: TO_DATE(TO_CHAR(date_column, nls_date_format), non_default_format_mask)

Generally, the default nls_date_format parameter is set to dd-MON-yy, so in your query, what is likely to be happening is your date column is converted to a string in the format dd-MON-yy, and you're then turning it back to a date using the format MMDD. The string is not in this format, so you get an error.

See also https://github.com/angular/angular/blob/master/CHANGELOG.md#500-beta5-2017-08-29

original

Templates (<template>, or <ng-template> since 4.x) are added as embedded views and get passed a context.

With let-col the context property $implicit is made available as col within the template for bindings. With let-foo="bar" the context property bar is made available as foo.

For example if you add a template

<ng-template #myTemplate let-col let-foo="bar">
  <div>{{col}}</div>
  <div>{{foo}}</div>
</ng-template>

<!-- render above template with a custom context -->
<ng-template [ngTemplateOutlet]="myTemplate"
             [ngTemplateOutletContext]="{
                                           $implicit: 'some col value',
                                           bar: 'some bar value'
                                        }"
></ng-template>

See also this answer and ViewContainerRef#createEmbeddedView.

*ngFor also works this way. The canonical syntax makes this more obvious

<ng-template ngFor let-item [ngForOf]="items" let-i="index" let-odd="odd">
  <div>{{item}}</div>
</ng-template>

where NgFor adds the template as embedded view to the DOM for each item of items and adds a few values (item, index, odd) to the context.

(Similar to Doin idea) To show what is being matched, I use this code

$keys = array_keys($_GET);
foreach($keys as $i=>$key){
    echo "$i => $key <br>";
}

Save it to r.php on the server root and then do some tests in .htaccess
For example, i want to match urls that do not start with a language prefix

RewriteRule ^(?!(en|de)/)(.*)$ /r.php?$1&$2 [L] #$1&$2&...
RewriteRule ^(.*)$ /r.php?nomatch [L] #report nomatch and exit

In easy language, both versions are absolutely the same. Only difference is:

• min.js is for websites (online)

• .js is for developers, guys who needs to read, learn about or/and understand jquery codes, for ie plugin development (offline, local work).

You can also use a background image replacement as an alternative, giving you total control over vertical and horizontal positioning.

See the answer to this Question

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

case the column isn't string, use astype to convert:

df['col'] = df['col'].astype(str).str[:9]

        int[] numbers = {1,2,3,4,5,3,6,4,7,8,9,1,0 };
        var nonRepeats = (from n in numbers select n).Distinct();


        foreach (var d in nonRepeats)
        {

            Response.Write(d);
        }

An excellent 2014 IBM research paper “An Updated Performance Comparison of Virtual Machines and Linux Containers” by Felter et al. provides a comparison between bare metal, KVM, and Docker containers. The general result is: Docker is nearly identical to native performance and faster than KVM in every category.

The exception to this is Docker’s NAT — if you use port mapping (e.g., docker run -p 8080:8080), then you can expect a minor hit in latency, as shown below. However, you can now use the host network stack (e.g., docker run --net=host) when launching a Docker container, which will perform identically to the Native column (as shown in the Redis latency results lower down).

They also ran latency tests on a few specific services, such as Redis. You can see that above 20 client threads, highest latency overhead goes Docker NAT, then KVM, then a rough tie between Docker host/native.

Just because it’s a really useful paper, here are some other figures. Please download it for full access.

Taking a look at Disk I/O:

Now looking at CPU overhead:

Now some examples of memory (read the paper for details, memory can be extra tricky):

Here is the example i have tried and it is working for me:

Create the XML file SoapRequestFile.xml

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
       <soapenv:Header/>
       <soapenv:Body>
          <tem:GetConversionRate>
             <!--Optional:-->
             <tem:CurrencyFrom>USD</tem:CurrencyFrom>
             <!--Optional:-->
             <tem:CurrencyTo>INR</tem:CurrencyTo>
             <tem:RateDate>2018-12-07</tem:RateDate>
          </tem:GetConversionRate>
       </soapenv:Body>
    </soapenv:Envelope>

And here the code in java:

            public void getMethod() throws Exception  {
                //wsdl file :http://currencyconverter.kowabunga.net/converter.asmx?wsdl
                File soapRequestFile = new File(".\\SOAPRequest\\SoapRequestFile.xml");

                CloseableHttpClient client = HttpClients.createDefault(); //create client
                HttpPost request = new HttpPost("http://currencyconverter.kowabunga.net/converter.asmx"); //Create the request
                request.addHeader("Content-Type", "text/xml"); //adding header
                request.setEntity(new InputStreamEntity(new FileInputStream(soapRequestFile)));
                CloseableHttpResponse response =  client.execute(request);//Execute the command

                int statusCode=response.getStatusLine().getStatusCode();//Get the status code and assert
                System.out.println("Status code: " +statusCode );
                Assert.assertEquals(200, statusCode);

                String responseString = EntityUtils.toString(response.getEntity(),"UTF-8");//Getting the Response body
                System.out.println(responseString);


                XmlPath jsXpath= new XmlPath(responseString);//Converting string into xml path to assert
                String rate=jsXpath.getString("GetConversionRateResult");
                System.out.println("rate returned is: " +  rate);



        }

The solution is simple.

After installing Node, you should restart your VScode and run npm install command.

HTTP is called as a stateless protocol because each request is executed independently, without any knowledge of the requests that were executed before it, which means once the transaction ends the connection between the browser and the server is also lost.

What makes the protocol stateless is that in its original design, HTTP is a relatively simple file transfer protocol:

1. make a request for a file named by a URL,
2. get the file in response,
3. disconnect.

There was no relationship maintained between one connection and another, even from the same client. This simplifies the contract between client and server, and in many cases minimizes the amount of data that needs to be transferred.

My answer is based on this answer: How can I get the current contents of an element in webdriver just more like copy-paste.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get('http://www.w3c.org')
element = driver.find_element_by_name('q')
element.send_keys('hi mom')

element_text = element.text
element_attribute_value = element.get_attribute('value')

print (element)
print ('element.text: {0}'.format(element_text))
print ('element.get_attribute(\'value\'): {0}'.format(element_attribute_value))


element = driver.find_element_by_css_selector('.description.expand_description > p')
element_text = element.text
element_attribute_value = element.get_attribute('value')

print (element)
print ('element.text: {0}'.format(element_text))
print ('element.get_attribute(\'value\'): {0}'.format(element_attribute_value))
driver.quit()

If you need to know the class name that was called from inside a class, and don't want the namespace, you can use this one

$calledClass = get_called_class();
$name = strpos($calledClass, '\\') === false ?
    $calledClass : substr($calledClass, strrpos($calledClass, '\\') + 1);

This is great when you have a method inside a class which is extended by other classes. Furthermore, this also works if namespaces aren't used at all.

Example:

<?php
namespace One\Two {
    class foo
    {
        public function foo()
        {
            $calledClass = get_called_class();
            $name = strpos($calledClass, '\\') === false ?
                $calledClass : substr($calledClass, strrpos($calledClass, '\\') + 1);

            var_dump($name);
        }
    }
}

namespace Three {
    class bar extends \One\Two\foo
    {
        public function bar()
        {
            $this->foo();
        }
    }
}

namespace {
    (new One\Two\foo)->foo();
    (new Three\bar)->bar();
}

// test.php:11:string 'foo' (length=3)
// test.php:11:string 'bar' (length=3)

You can also set the global option:

objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

Adding java.util.list will resolve your problem because List interface which you are trying to use is part of java.util.list package.

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

There are a few different options on how to do this. The most basic is to use varargin, and then use nargin, size etc. to determine whether the optional arguments have been passed to the function.

% Function that takes two arguments, X & Y, followed by a variable 
% number of additional arguments
function varlist(X,Y,varargin)
   fprintf('Total number of inputs = %d\n',nargin);

   nVarargs = length(varargin);
   fprintf('Inputs in varargin(%d):\n',nVarargs)
   for k = 1:nVarargs
      fprintf('   %d\n', varargin{k})
   end

A little more elegant looking solution is to use the inputParser class to define all the arguments expected by your function, both required and optional. inputParser also lets you perform type checking on all arguments.

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

Have a look at ORDER BY Optimization

You need to find (or define) a 'get' template tag, for example, here.

The tag definition:

@register.filter
def hash(h, key):
    return h[key]

And it’s used like:

{% for o in objects %}
  <li>{{ dictionary|hash:o.id }}</li>
{% endfor %}

The latest dwr (http://directwebremoting.org/dwr/index.html) has ajax file uploads, complete with examples and nice stuff for users (like progress indicators and such).

It looks pretty nifty and dwr is fairly easy to use in general so this will be pretty good as well.

An asynchronous version of extension function:

    public static async Task<WebResponse> GetResponseAsyncNoEx(this WebRequest request)
    {
        try
        {
            return await request.GetResponseAsync();
        }
        catch(WebException ex)
        {
            return ex.Response;
        }
    }

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
        $("div").addClass(function(){
            return "par" ;
    });
});
</script>
<style>
.par {
    color: blue;
}
</style>
</head>
<body>
<div class="test">This is a paragraph.</div>
</body>
</html>

Yes it is true.

If you create two instance of your class

Test t1 = new Test();
Test t2 = new Test();

Then t1.foo and t2.foo both synchronize on the same static object and hence block each other.

Problem here is you are trying to open a mongo shell without starting a mongo db which is listening to port 127.0.0.1:27017(deafault for mongo db) thats what the error is all about:

Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145 exception: connect failed

The easiest solution is to open the terminal and type

$ mongod --dbpath ~/data/db

Note: dbpath here is "Users/user" where data/db directories are created

i.e., you need to create directory data and sub directory db in your user folder. For e.g say `

/Users/johnny/data

After mongo db is up. Open another terminal in new window and type

$ mongo

it will open mongo shell with your mongo db connection opened in another terminal.

Try:

error: function(xhr, status, error) {
  var err = eval("(" + xhr.responseText + ")");
  alert(err.Message);
}

I couldn't find a neat way in the end so I went for create a directory called local_modules and then added this bashscript to the package.json in scripts->preinstall

#!/bin/sh
for i in $(find ./local_modules -type d -maxdepth 1) ; do
    packageJson="${i}/package.json"
    if [ -f "${packageJson}" ]; then
        echo "installing ${i}..."
        npm install "${i}"
    fi
done

You just declared a jagged array. Such kind of arrays can have different sizes for all dimensions. For example:

string[][] jaggedStrings =  {
new string[] {"x","y","z"},
new string[] {"x","y"},
new string[] {"x"}
};

In your case you need regular array. See answers above. More about jagged arrays

If you define a class without any constructor, the compiler will synthesize a constructor for you (and that will be a default constructor -- i.e., one that doesn't require any arguments). If, however, you do define a constructor, (even if it does take one or more arguments) the compiler will not synthesize a constructor for you -- at that point, you've taken responsibility for constructing objects of that class, so the compiler "steps back", so to speak, and leaves that job to you.

You have two choices. You need to either provide a default constructor, or you need to supply the correct parameter when you define an object. For example, you could change your constructor to look something like:

Blowfish(BlowfishAlgorithm algorithm = CBC);

...so the ctor could be invoked without (explicitly) specifying an algorithm (in which case it would use CBC as the algorithm).

The other alternative would be to explicitly specify the algorithm when you define a Blowfish object:

class GameCryptography { 
    Blowfish blowfish_;
public:
    GameCryptography() : blowfish_(ECB) {}
    // ...
};

In C++ 11 (or later) you have one more option available. You can define your constructor that takes an argument, but then tell the compiler to generate the constructor it would have if you didn't define one:

class GameCryptography { 
public:

    // define our ctor that takes an argument
    GameCryptography(BlofishAlgorithm); 

    // Tell the compiler to do what it would have if we didn't define a ctor:
    GameCryptography() = default;
};

As a final note, I think it's worth mentioning that ECB, CBC, CFB, etc., are modes of operation, not really encryption algorithms themselves. Calling them algorithms won't bother the compiler, but is unreasonably likely to cause a problem for others reading the code.

I have the same problem as @KTCheek in that I need it to execute sequentially. However I figured I would try using IAsyncEnumerable (introduced in .NET Core 3) and await foreach (introduced in C# 8). Here's what I have come up with:

public static class IEnumerableExtensions {
    public static async IAsyncEnumerable<TResult> SelectAsync<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> selector) {
        foreach (var item in source) {
            yield return await selector(item);
        }
    }
}

public static class IAsyncEnumerableExtensions {
    public static async Task<List<TSource>> ToListAsync<TSource>(this IAsyncEnumerable<TSource> source) {
        var list = new List<TSource>();

        await foreach (var item in source) {
            list.Add(item);
        }

        return list;
    }
}

This can be consumed by saying:

var inputs = await events.SelectAsync(ev => ProcessEventAsync(ev)).ToListAsync();

Update: Alternatively you can add a reference to "System.Linq.Async" and then you can say:

var inputs = await events
    .ToAsyncEnumerable()
    .SelectAwait(async ev => await ProcessEventAsync(ev))
    .ToListAsync();

-ErrorAction Stop is changing things for you. Try adding this and see what you get:

Catch [System.Management.Automation.ActionPreferenceStopException] {
"caught a StopExecution Exception" 
$error[0]
}

If you are using Grail's Framework, it's simple to resolve lazy initialization exception by using Lazy keyword on specific field in Domain Class.

For-example:

class Book {
    static belongsTo = [author: Author]
    static mapping = {
        author lazy: false
    }
}

came to this question via google.

Here is what i did in the simplest way.

git checkout branch_to_clone

then create a new git branch from this branch

git checkout -b new_cloned_branch
Switched to branch 'new_cloned_branch'

come back to original branch and continue:

git checkout branch_to_clone

Assuming you screwed up and need to restore something from backup branch :

git checkout new_cloned_branch -- <filepath>  #notice the space before and after "--"

Best part if anything is screwed up, you can just delete the source branch and move back to backup branch!!

IE doesn't allow this anymore (since Version 10, I believe) and will ignore such scripts. FF and Chrome still tolerate them, but there are chances that some day they will drop this as non-standard.

If you forgot your password or want to change it to your mysql:

1. start your terminal and enter:

sudo su

2. Enter pass for you system
3. Stop your mysql:

sudo /usr/local/mysql/support-files/mysql.server stop

4. Leave this window OPEN, run second terminal window and enter here:

mysql -u root

5. And change your password for mysql:

UPDATE mysql.user SET authentication_string=PASSWORD('new_password') WHERE User='root';

where "new_password" - your new pass. You don't need old pass for mysql.

6. Flush, quit and check your new pass:

FLUSH PRIVILEGES;

7. Close all windows and check your new pass for mysql. Good luck.

You can use this JavaScript function. Here you can display Redirection message to the user and redirected to the given URL.

<script type="text/javascript">   
    function Redirect() 
    {  
        window.location="http://www.newpage.com"; 
    } 
    document.write("You will be redirected to a new page in 5 seconds"); 
    setTimeout('Redirect()', 5000);   
</script>

Whenever you are in the following situation:

a = []
for i in range(5):
    a.append(i)

and you want something similar in numpy, several previous answers have pointed out ways to do it, but as @katrielalex pointed out these methods are not efficient. The efficient way to do this is to build a long list and then reshape it the way you want after you have a long list. For example, let's say I am reading some lines from a file and each row has a list of numbers and I want to build a numpy array of shape (number of lines read, length of vector in each row). Here is how I would do it more efficiently:

long_list = []
counter = 0
with open('filename', 'r') as f:
    for row in f:
        row_list = row.split()
        long_list.extend(row_list)
        counter++
#  now we have a long list and we are ready to reshape
result = np.array(long_list).reshape(counter, len(row_list)) #  desired numpy array

I faced the similar problem. In my case I had created the new virtual device and had enabled the snapshot. I just unchecked the checkbox Go to AVD Manager -> Select the device -> click Edit and uncheck the Enabled checkbox. I hope this works.

Note that ng-bind-html-unsafe is no longer suppported in rc 1.2. Use ng-bind-html instead. See: With ng-bind-html-unsafe removed, how do I inject HTML?

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

Refer to Section 8.3 of this SAML core pdf of oasis SAML specification.

SP and IdP usually communicate each other about a subject. That subject should be identified through a NAME-IDentifier , which should be in some format so that It is easy for the other party to identify it based on the Format.

All these

1.urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified [default]

2.urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress

3.urn:oasis:names:tc:SAML:2.0:nameid-format:persistent

4.urn:oasis:names:tc:SAML:2.0:nameid-format:transient

are format for the Name Identifiers.

The name format for a transient ID in SAML 1 is urn:mace:shibboleth:1.0:nameIdentifier and in SAML 2 is urn:oasis:names:tc:SAML:2.0:nameid-format:transient

Transient is for [section 8.3.8 of SAML Core]

Indicates that the content of the element is an identifier with transient semantics and SHOULD be treated as an opaque and temporary value by the relying party.

Unspecified can be used and it purely depends on the entities implementation on their own wish.

I just made a class to handle this with Generics, so it can be used with all the object types that are serializable:

        } catch (IOException | ClassNotFoundException e) {
            e.printStackTrace();
        }

        return objectToReturn;

    /**

}

In Web-"MVC" you can do whatever you please.

The original concept ⁽¹⁾ described the model as the business logic. It should represent the application state and enforce some data consistency. That approach is often described as "fat model".

Most PHP frameworks follow a more shallow approach, where the model is just a database interface. But at the very least these models should still validate the incoming data and relations.

Either way, you're not very far off if you separate the SQL stuff or database calls into another layer. This way you only need to concern yourself with the real data/behaviour, not with the actual storage API. (It's however unreasonable to overdo it. You'll e.g. never be able to replace a database backend with a filestorage if that wasn't designed ahead.)

From Python 2.5 onwards you can do:

value = b if a > 10 else c

Previously you would have to do something like the following, although the semantics isn't identical as the short circuiting effect is lost:

value = [c, b][a > 10]

There's also another hack using 'and ... or' but it's best to not use it as it has an undesirable behaviour in some situations that can lead to a hard to find bug. I won't even write the hack here as I think it's best not to use it, but you can read about it on Wikipedia if you want.

If you only need two decimal places, simplest way is..

SELECT CAST(12 AS DECIMAL(16,2))

OR

SELECT CAST('12' AS DECIMAL(16,2))

Output

12.00

You can use getnameinfo for Windows and for Linux.

Assuming you have a good (i.e. it's members have appropriate values) sockaddr* called pSockaddr:

char clienthost[NI_MAXHOST];  //The clienthost will hold the IP address.
char clientservice[NI_MAXSERV];
int theErrorCode = getnameinfo(pSockaddr, sizeof(*pSockaddr), clienthost, sizeof(clienthost), clientservice, sizeof(clientservice), NI_NUMERICHOST|NI_NUMERICSERV);

if( theErrorCode != 0 )
{
    //There was an error.
    cout << gai_strerror(e1) << endl;
}else{
    //Print the info.
    cout << "The ip address is = " << clienthost << endl;
    cout << "The clientservice = " << clientservice << endl;
}

You can force a file to be interpreted as a particular type by specifying an option, e.g.:

@import (css) "lib";

will output

@import "lib";

and

@import (less) "lib.css";

will import the lib.css file and treat it as less. If you specify a file is less and do not include an extension, none will be added.

[0-9] is not always equivalent to \d. In python3, [0-9] matches only 0123456789 characters, while \d matches [0-9] and other digit characters, for example Eastern Arabic numerals ??????????.

Also, you could try triggering a mouseover.

$("#btn").click(function() {
   $("#link").trigger("mouseover");
});

Not sure if this will work for your specific scenario, but I've had success triggering mouseover instead of hover for various cases.

This is a good thing to handle with a revision control system. That way when you get a bug report from a user, you can check out that revision of code and (hopefully) reproduce the bug running the exact same code as the user.

The idea is that every time you do a build, you will run a script that gets the current revision number of your code and updates a file within your project (usually with some form of token replacement). You can then write an error handling routine that always includes the revision number in the error output, or you can display it on an "About" page.

Note: This solution changes based on viewport size and not the amount of content

I just found out that this is possible using VW units. They're the units associated with setting the viewport width. There are some drawbacks, such as lack of legacy browser support, but this is definitely something to seriously consider using. Plus you can still provide fallbacks for older browsers like so:

p {
    font-size: 30px;
    font-size: 3.5vw;
}

http://css-tricks.com/viewport-sized-typography/ and https://medium.com/design-ux/66bddb327bb1

The other difference is that

template<class T> ...

is allowed, but

template<struct T> ...

is not.

GLM has good example of rotation : http://glm.g-truc.net/code.html

glm::mat4 Projection = glm::perspective(45.0f, 4.0f / 3.0f, 0.1f, 100.f);
glm::mat4 ViewTranslate = glm::translate(
    glm::mat4(1.0f),
    glm::vec3(0.0f, 0.0f, -Translate)
);
glm::mat4 ViewRotateX = glm::rotate(
    ViewTranslate,
    Rotate.y,
    glm::vec3(-1.0f, 0.0f, 0.0f)
);
glm::mat4 View = glm::rotate(
    ViewRotateX,
    Rotate.x,
    glm::vec3(0.0f, 1.0f, 0.0f)
);
glm::mat4 Model = glm::scale(
    glm::mat4(1.0f),
    glm::vec3(0.5f)
);
glm::mat4 MVP = Projection * View * Model;
glUniformMatrix4fv(LocationMVP, 1, GL_FALSE, glm::value_ptr(MVP));

Open git repository on browser, got to "Setttings", you can see rename button.

Input new "Repository Name" and click "Rename" button.

You need to add a reference to the .NET assembly System.Data.Linq

I encountered a similar problem, with a syntax error that I knew should not be a syntax error. In my case it turned out that a Python 2 interpreter was trying to run Python 3 code, or vice versa; I think that my shell had a PYTHONPATH with a mixture of Python 2 and Python 3.

There is another option that worked for me:

Subclass UITextField and overwrite:

- (void)drawTextInRect:(CGRect)rect

In this method you can for example:

    NSDictionary *attributes = @{ NSFontAttributeName : self.font,
                                  NSForegroundColorAttributeName : self.textColor };

    [self.text drawInRect:verticalAlignedRect withAttributes:attributes];

This code will render the text using as many lines as required if the rect has enough space. You could specify any other attribute depending on your needs.

Do not use:

self.defaultTextAttributes

which will force one line text rendering

The functions.php file doesn't have anything to do with login redirect, what you should be considering it's the wp-login.php file, you can actually change the entire login interface from there, and force users to redirect to your custom pages instead of the /wp-admin/ directory.

Open the file with Notepad if using Windows or any text editor, Prese Ctrl + F (on window) Find "wp-admin/" and change it to the folder you want it to redirect to after login, still on the same file Press Ctrl + F, find "admin_url" and the change the file name, the default file name there is "profile.php"...after just save and give a try.

if ( !$user->has_cap('edit_posts') && ( empty( $redirect_to ) || $redirect_to == 'wp-admin/' || $redirect_to == admin_url() ) )
        $redirect_to = admin_url('profile.php');
    wp_safe_redirect($redirect_to);
    exit();

Or you can use the "registration-login plugin" http://wordpress.org/extend/plugins/registration-login/, just simple edit the redirect urls and the links to where you want it to redirect after login, and you've got your very own custom profile.

DELETE Table1
FROM Table1
INNER JOIN Table2 ON Table1.ID = Table2.ID

Both of these are primary from the old printing days.

Carriage return is from the days of the teletype printers/old typewriters, where literally the carriage would return to the next line, and push the paper up. This is what we now call \r.

Line feed LF signals the end of the line, it signals that the line has ended - but doesn't move the cursor to the next line. In other words, it doesn't "return" the cursor/printer head to the next line.

For more sundry details, the mighty wikipedia to the rescue.

I arrived here because I thought I should check in SO if there are adequate answers, after a syntax error that gave me this error, or if I could possibly post an answer myself.

OK, the answers here explain what this error is, so not much more to say, but nevertheless I will give my 2 cents using my words:

This error is caused by the fact that you basically generate a new table with your subquery for the FROM command.

That's what a derived table is, and as such, it needs to have an alias (actually a name reference to it).

So given the following hypothetical query:

SELECT id, key1
FROM (
    SELECT t1.ID id, t2.key1 key1, t2.key2 key2, t2.key3 key3
    FROM table1 t1 
    LEFT JOIN table2 t2 ON t1.id = t2.id
    WHERE t2.key3 = 'some-value'
) AS tt

So, at the end, the whole subquery inside the FROM command will produce the table that is aliased as tt and it will have the following columns id, key1, key2, key3.

So, then with the initial SELECT from that table we finally select the id and key1 from the tt.

Or add "sort name" to list alphabetically

Get-ADPrincipalGroupMembership username | select name | sort name

Hope this will help you

Cast(columnName as Numeric(10,2)) 
        or

Cast(@s as decimal(10,2))

I am not getting why you want to cast to varchar?.If you cast to varchar again convert back to decimail for two decimal points

Check out the range documentation, you have to define a negative step:

>>> range(10, 0, -1)
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

ISNA is the best function to use. I just did. I wanted all cells whose value was NOT in an array to conditionally format to a certain color.

=ISNA(VLOOKUP($A2,Sheet1!$A:$D,2,FALSE))

1: Add the following line into the AssemblyInfo class

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

2: Make sure you don't use .Net Framework 4 Client Profile as Target Framework (I think this is OK on your side because otherwise it even wouldn't compile)

3: Make sure you log very early in your program. Otherwise, in some scenarios, it will not be initialized properly (read more on log4net FAQ).

So log something during application startup in the Global.asax

public class Global : System.Web.HttpApplication
{
    private static readonly log4net.ILog Log = log4net.LogManager.GetLogger(typeof(Global));
    protected void Application_Start(object sender, EventArgs e)
    {
        Log.Info("Startup application.");
    }
}

4: Make sure you have permission to create files and folders on the given path (if the folder itself also doesn't exist)

5: The rest of your given information looks ok

This works for me:

try {
       $statusUpdate = $facebook->api('/me/feed', 'post',
                 array('name'=>'My APP on Facebook','message'=> 'I am here working',
                 'privacy'=> array('value'=>'CUSTOM','friends'=>'SELF'),
                 'description'=>'testing my description',
                 'picture'=>'https://fbcdn-photos-a.akamaihd.net/mypicture.gif',
                 'caption'=>'apps.facebook.com/myapp','link'=>'http://apps.facebook.com/myapp'));
 } catch (FacebookApiException $e) {
      d($e);
}

<h:button>

The <h:button> generates a HTML <input type="button">. The generated element uses JavaScript to navigate to the page given by the attribute outcome, using a HTTP GET request.

E.g.

<h:button value="GET button" outcome="otherpage" />

will generate

<input type="button" onclick="window.location.href='/contextpath/otherpage.xhtml'; return false;" value="GET button" />

Even though this ends up in a (bookmarkable) URL change in the browser address bar, this is not SEO-friendly. Searchbots won't follow the URL in the onclick. You'd better use a <h:outputLink> or <h:link> if SEO is important on the given URL. You could if necessary throw in some CSS on the generated HTML <a> element to make it to look like a button.

Do note that while you can put an EL expression referring a method in outcome attribute as below,

<h:button value="GET button" outcome="#{bean.getOutcome()}" />

it will not be invoked when you click the button. Instead, it is already invoked when the page containing the button is rendered for the sole purpose to obtain the navigation outcome to be embedded in the generated onclick code. If you ever attempted to use the action method syntax as in outcome="#{bean.action}", you would already be hinted by this mistake/misconception by facing a javax.el.ELException: Could not find property actionMethod in class com.example.Bean.

If you intend to invoke a method as result of a POST request, use <h:commandButton> instead, see below. Or if you intend to invoke a method as result of a GET request, head to Invoke JSF managed bean action on page load or if you also have GET request parameters via <f:param>, How do I process GET query string URL parameters in backing bean on page load?

<h:commandButton>

The <h:commandButton> generates a HTML <input type="submit"> button which submits by default the parent <h:form> using HTTP POST method and invokes the actions attached to action, actionListener and/or <f:ajax listener>, if any. The <h:form> is required.

E.g.

<h:form id="form">
    <h:commandButton id="button" value="POST button" action="otherpage" />
</h:form>

will generate

<form id="form" name="form" method="post" action="/contextpath/currentpage.xhtml" enctype="application/x-www-form-urlencoded">
    <input type="hidden" name="form" value="form" />
    <input type="submit" name="form:button" value="POST button" />
    <input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="...." autocomplete="off" />
</form>

Note that it thus submits to the current page (the form action URL will show up in the browser address bar). It will afterwards forward to the target page, without any change in the URL in the browser address bar. You could add ?faces-redirect=true parameter to the outcome value to trigger a redirect after POST (as per the Post-Redirect-Get pattern) so that the target URL becomes bookmarkable.

The <h:commandButton> is usually exclusively used to submit a POST form, not to perform page-to-page navigation. Normally, the action points to some business action, such as saving the form data in DB, which returns a String outcome.

<h:commandButton ... action="#{bean.save}" />

with

public String save() {
    // ...
    return "otherpage";
}

Returning null or void will bring you back to the same view. Returning an empty string also, but it would recreate any view scoped bean. These days, with modern JSF2 and <f:ajax>, more than often actions just return to the same view (thus, null or void) wherein the results are conditionally rendered by ajax.

public void save() {
    // ...
}

fromHtml

This method was deprecated in API level 24.

You should use FROM_HTML_MODE_LEGACY

Separate block-level elements with blank lines (two newline characters) in between. This is the legacy behavior prior to N.

Code

if (Build.VERSION.SDK_INT >= 24)
        {
            etOBJ.setText(Html.fromHtml("Intellij \n Amiyo",Html.FROM_HTML_MODE_LEGACY));

         }
 else
        {
           etOBJ.setText(Html.fromHtml("Intellij \n Amiyo"));
        }

For Kotlin

fun setTextHTML(html: String): Spanned
    {
        val result: Spanned = if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
            Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY)
        } else {
            Html.fromHtml(html)
        }
        return result
    }

Call

 txt_OBJ.text  = setTextHTML("IIT Amiyo")

check your tab order and make sure the textbox is set to zero

dont install git on a server or copy the .git folder there. to update a server from a git clone you can use following command:

git ls-files -z | rsync --files-from - --copy-links -av0 . [email protected]:/var/www/project

you might have to delete files which got removed from the project.

this copies all the checked in files. rsync uses ssh which is installed on a server anyways.

the less software you have installed on a server the more secure he is and the easier it is to manage it's configuration and document it. there is also no need to keep a complete git clone on the server. it only makes it more complex to secure everything properly.

inputString.splitlines()

Will give you a list with each item, the splitlines() method is designed to split each line into a list element.

You can use the built-in class XAttribute, which handles the encoding automatically:

using System.Xml.Linq;

XDocument doc = new XDocument();

List<XAttribute> attributes = new List<XAttribute>();
attributes.Add(new XAttribute("key1", "val1&val11"));
attributes.Add(new XAttribute("key2", "val2"));

XElement elem = new XElement("test", attributes.ToArray());

doc.Add(elem);

string xmlStr = doc.ToString();

This is example:

$.ajax({
  url: "test.html",
  async: false
}).done(function(data) {
   // Todo something..
}).fail(function(xhr)  {
   // Todo something..
});

The definition of an inline function doesn't have to be in a header file but, because of the one definition rule (ODR) for inline functions, an identical definition for the function must exist in every translation unit that uses it.

The easiest way to achieve this is by putting the definition in a header file.

If you want to put the definition of a function in a single source file then you shouldn't declare it inline. A function not declared inline does not mean that the compiler cannot inline the function.

Whether you should declare a function inline or not is usually a choice that you should make based on which version of the one definition rules it makes most sense for you to follow; adding inline and then being restricted by the subsequent constraints makes little sense.

This worked for me to stop silly work breaks from happening within Chrome textareas

word-break: keep-all;

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

      <plugin>
        <artifactId>exec-maven-plugin</artifactId>
        <groupId>org.codehaus.mojo</groupId>
        <inherited>false</inherited>
        <executions>
          <execution>
            <id>Check that there are no Windows line endings</id>
            <phase>compile</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>${build.path}/style/check_no_windows_line_endings.sh</executable>
            </configuration>
          </execution>
        </executions>
      </plugin>

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.

ma
move cursor down
:'a,.!program

This will take all text between where you set the a mark (ma) to the current line (.), run it through program, and replace the contents of the marked region with the results. You can even use it to see the contents of a directory (for example) by making a blank line, then with cursor sitting on that line,

:.!ls

Oh, and you can set marks like this for a-z (i.e. ma), and

'a

will jump you to the position you marked as "a."

/ searches forward, and ? repeats search backwards without having to resupply search pattern.

Groovy stuff. vi is highly underrated. Once you get the hang of it, you won't ever want to use the IDE supplied editors.

Running the app on a virtual device with system image, 'Google Play API' instead of 'Google API' will solve your issue smoothly..

• Virtual devices Nexus 5x and Nexus 5 supports 'Google Play API' image.

• Google Play API comes with Nougat 7.1.1 and O 8.0.

Just follow the below simple steps and make sure your pc is connected to internet.

1. Create a new virtual device by selecting Create Virtual Device(left-bottom corner) from Android Virtual Devices Manager.

2. Select the Hardware 'Nexus 5x' or 'Nexus 5'.

3. Download the system image 'Nougat' with Google Play or 'O' with Google Play. 'O' is the latest Android 8.0 version.

4. Click on Next and Finish.

5. Run your app again on the new virtual device and click on the 'Upgrade now ' option that shows along with the warning message.

6. You will be directed to the Play Store and you can update your Google Play services easily.

See your app runs smoothly!

• Note: If you plan to use APIs from Google Play services, you must use the Google APIs System Image.

When you normalize a matrix using NORM_L1, you are dividing every pixel value by the sum of absolute values of all the pixels in the image. As a result, all pixel values become much less than 1 and you get a black image. Try NORM_MINMAX instead of NORM_L1.

You cannot update it. You'll have to save the document using a new _id, and then remove the old document.

// store the document in a variable
doc = db.clients.findOne({_id: ObjectId("4cc45467c55f4d2d2a000002")})

// set a new _id on the document
doc._id = ObjectId("4c8a331bda76c559ef000004")

// insert the document, using the new _id
db.clients.insert(doc)

// remove the document with the old _id
db.clients.remove({_id: ObjectId("4cc45467c55f4d2d2a000002")})

There is a nice read on Default parameters in ES6 on the MDN website here.
In ES6 you can now do the following:

secondDefaultValue = 'indirectSecondDefaultValue';

function MyObject( param1 = 'firstDefaultValue', param2 = secondDefaultValue ){
    this.first = param1;
    this.second = param2;
}

You can use this also as follows:

var object = new MyObject( undefined, options );

Which will set default value 'firstDefaultValue' for first param1 and your options for second param2.

Here a demonstration in a fiddle

Try this:

select * from T_PARTNER 
where C_DISTRIBUTOR_TYPE_ID = 6 and
translate(C_PARTNER_ID, '.1234567890', '.') is null;

Well, performance impact is mostly insignificant, but isn't zero. If you look at JavaDoc of RandomAccess interface:

As a rule of thumb, a List implementation should implement this interface if, for typical instances of the class, this loop:

for (int i=0, n=list.size(); i < n; i++)
    list.get(i);

runs faster than this loop:

for (Iterator i=list.iterator(); i.hasNext();)
      i.next();

And for-each loop is using version with iterator, so for ArrayList for example, for-each loop isn't fastest.

As explained in short C# (but also for other language compilers as well, like Java)

There is a predefined implicit conversion from short to int, long, float, double, or decimal.

You cannot implicitly convert nonliteral numeric types of larger storage size to short (see Integral Types Table for the storage sizes of integral types). Consider, for example, the following two short variables x and y:

short x = 5, y = 12;

The following assignment statement will produce a compilation error, because the arithmetic expression on the right-hand side of the assignment operator evaluates to int by default.

short z = x + y;   // Error: no conversion from int to short

To fix this problem, use a cast:

short z = (short)(x + y);   // OK: explicit conversion

It is possible though to use the following statements, where the destination variable has the same storage size or a larger storage size:

int m = x + y;
long n = x + y;

A good follow-up question is:

"why arithmetic expression on the right-hand side of the assignment operator evaluates to int by default" ?

A first answer can be found in:

Classifying and Formally Verifying Integer Constant Folding

The Java language specification defines exactly how integer numbers are represented and how integer arithmetic expressions are to be evaluated. This is an important property of Java as this programming language has been designed to be used in distributed applications on the Internet. A Java program is required to produce the same result independently of the target machine executing it.

In contrast, C (and the majority of widely-used imperative and object-oriented programming languages) is more sloppy and leaves many important characteristics open. The intention behind this inaccurate language specification is clear. The same C programs are supposed to run on a 16-bit, 32-bit, or even 64-bit architecture by instantiating the integer arithmetics of the source programs with the arithmetic operations built-in in the target processor. This leads to much more e?cient code because it can use the available machine operations directly. As long as the integer computations deal only with numbers being “sufficiently small”, no inconsistencies will arise.

In this sense, the C integer arithmetic is a placeholder which is not defined exactly by the programming language specification but is only completely instantiated by determining the target machine.

Java precisely defines how integers are represented and how integer arithmetic is to be computed.

      Java Integers
--------------------------
Signed         |  Unsigned
--------------------------
long  (64-bit) |
int   (32-bit) |
short (16-bit) |  char (16-bit)
byte  (8-bit)  |

Char is the only unsigned integer type. Its values represent Unicode characters, from \u0000 to \uffff, i.e. from 0 to 2¹⁶-1.

If an integer operator has an operand of type long, then the other operand is also converted to type long. Otherwise the operation is performed on operands of type int, if necessary shorter operands are converted into int. The conversion rules are exactly specified.

Building on lonesomeday's example (upvote that answer not this one), I ran into this output:

The cause was using a string as input. To fix it, prefix the string with a plus sign:

prettyDate(new Date(+datetime));

Hello i was able to import the packages from different directory. I just did the following: Note: I am using VScode

Steps to Create a Python Package Working with Python packages is really simple. All you need to do is:

Create a directory and give it your package's name. Put your classes in it. Create a init.py file in the directory

For example: you have a folder called Framework where you are keeping all the custom classes there and your job is to just create a init.py file inside the folder named Framework.

And while importing you need to import in this fashion--->

from Framework import base

so the E0401 error disappears Framework is the folder where you just created init.py and base is your custom module which you are required to import into and work upon Hope it helps!!!!

In datatable options put this:

$(document).ready( function() {
  $('#example').dataTable({
    "aaSorting": [[ 2, 'asc' ]], 
    //More options ...

   });
})

Here is the solution: "aaSorting": [[ 2, 'asc' ]],

2 means table will be sorted by third column,
asc in ascending order.

It means "not equal to" (as in, the values in cells E37-N37 are not equal to "", or in other words, they are not empty.)

Using Subversion with either the Apache module or svnserve. I've been able to perform operations as multiple users using --username.

Each time you invoke a Subversion command as a 'new' user, your $HOME/.subversion/auth/<authentication-method>/ directory will have a new entry cached for that user (assuming you are able to authenticate with the correct password or authentication method for the server you are contacting as that particular user).

Instead use:

df.head(500)

pip install mysql-connector

Last but not least,You can also install mysql-connector via source code

Download source code from: https://dev.mysql.com/downloads/connector/python/

I'm afraid this isn't possible with foreach. But I can suggest you a simple old-styled for-loops:

    List<String> l = new ArrayList<String>();

    l.add("a");
    l.add("b");
    l.add("c");
    l.add("d");

    // the array
    String[] array = new String[l.size()];

    for(ListIterator<String> it =l.listIterator(); it.hasNext() ;)
    {
        array[it.nextIndex()] = it.next();
    }

Notice that, the List interface gives you access to it.nextIndex().

(edit)

To your changed example:

    for(ListIterator<String> it =l.listIterator(); it.hasNext() ;)
    {
        int i = it.nextIndex();
        doSomethingWith(it.next(), i);
    }

A Java virtual machine (JVM) is a virtual machine that can execute Java ByteCode. It is the code execution component of the Java software platform.

The Java Development Kit (JDK) is an Oracle Corporation product aimed at Java developers. Since the introduction of Java, it has been by far the most widely used Java Software Development Kit (SDK).

Java Runtime Environment, is also referred to as the Java Runtime, Runtime Environment

OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java programming language. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GPL) with a linking exception.

Alternatively, if you are able to use external libraries, you can use filehound. It supports callbacks, promises and sync calls.

Using promises:

const Filehound = require('filehound');

Filehound.create()
  .path("MyFolder")
  .directory() // only search for directories
  .find()
  .then((subdirectories) => {
    console.log(subdirectories);
  });

Using callbacks:

const Filehound = require('filehound');

Filehound.create()
  .path("MyFolder")
  .directory()
  .find((err, subdirectories) => {
    if (err) return console.error(err);

    console.log(subdirectories);
  });

Sync call:

const Filehound = require('filehound');

const subdirectories = Filehound.create()
  .path("MyFolder")
  .directory()
  .findSync();

console.log(subdirectories);

For further information (and examples), check out the docs: https://github.com/nspragg/filehound

If the list is fixed in the script, I like the following the best:

validate() {
    grep -F -q -x "$1" <<EOF
item 1
item 2
item 3
EOF
}

Then use validate "$x" to test if $x is allowed.

If you want a one-liner, and don't care about whitespace in item names, you can use this (notice -w instead of -x):

validate() { echo "11 22 33" | grep -F -q -w "$1"; }

Notes:

• This is POSIX sh compliant.
• validate does not accept substrings (remove the -x option to grep if you want that).
• validate interprets its argument as a fixed string, not a regular expression (remove the -F option to grep if you want that).

Sample code to exercise the function:

for x in "item 1" "item2" "item 3" "3" "*"; do
    echo -n "'$x' is "
    validate "$x" && echo "valid" || echo "invalid"
done

Got it to work go to the local.properties file under your build.gradle files to find out the PATH to your SDK, from the SDK location go into the platform-tools folder and look and see if you have adb.exe.

If not go to http://adbshell.com/downloads and download ADB KITS. Copy the zip folder's contents into the platform-tools folder and re-make your project.

I didn't need to update the PATH in the Extended Controls Settings section on the emulator, I left Use detected ADB location settings on. Hope this makes this faster for you !

As Jeppe Stig Nielsen said, this thread already has great answers, but I thought this rather obvious subtlety was worth mentioning too.

using directives specified inside namespaces can make for shorter code since they don't need to be fully qualified as when they're specified on the outside.

The following example works because the types Foo and Bar are both in the same global namespace, Outer.

Presume the code file Foo.cs:

namespace Outer.Inner
{
    class Foo { }
}

And Bar.cs:

namespace Outer
{
    using Outer.Inner;

    class Bar
    {
        public Foo foo;
    }
}

That may omit the outer namespace in the using directive, for short:

namespace Outer
{
    using Inner;

    class Bar
    {
        public Foo foo;
    }
}

You don't need jQuery. You can do this using a for loop:

var total = 0;
for (var i = 0; i < someArray.length; i++) {
    total += someArray[i] << 0;
}

I know I'm late to the party but just wanted to mention that the Jumpout II theme really is amazing.. I have a lot of themes and this one really is great for a # of reasons..

1. it handles glare very well (yes even pure black on matte screens can produce glare, unfortunately my new matte monitor - has a more "glary" coating than my old one).. this is a grayish-black background

2. it has enough colors that you can easily see read even dense code - some themes that look nice at first use too much of one color and it makes dense code harder to digest

3. the comments are all gray, this is even better than dark green which is my 2nd favorite choice.. it really helps the code pop out..

so basically this is a great anti-glare, anti-dense-code theme

honorable mentions (I think these all can be found on that same site, although I'm not sure I spelled all of them correctly)

1. Dark Flash Builder (really great but at first the use of red can be confusing, but it is really one of its strengths. I had to modify it to make my error text highlighting different - I settled on some bright red underlined text)
2. Gedit Original Oblivion
3. Leone Dark II
4. Visual Studio 2013
5. Retta (very halloweeny)

and for white / beige / blue (in that order)

1. Oughsumm (wow best white ever, possibly the most legible theme I've ever seen - however, white is too bright for me in my current office situation, although occasionally I do switch to this when I want to quickly review a lot of code before a commit), also it is comfortably legible at 1 point smaller than all dark themes I've used.
2. humane-ist
3. rubyblue

p.s. please note I change the font of all the themes I use to Consolas 11 or 12 depending on the monitor. Consolas I find to be the best programming font out there. It looks great, easy to read and very well suited to LCD anti-aliasing. I tried so many programming fonts but I always come back to this one quickly. And it is not too narrow.. I'm not in the narrow camp, I believe narrow font aficionados don't program with ultra wide monitors - maybe program on a macbook or something just as bad :)

p.p.s I know solarized is supposed to be some kind of ultimate, magical, life-enhancing nirvana-inducing theme but I just don't get it.. I tried but failed to find it anything but annoying

CORS headers should be sent from the server. If you use PHP it will be like this:

header('Access-Control-Allow-Origin: your-host');
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Allow-Methods: your-methods like POST,GET');
header('Access-Control-Allow-Headers: content-type or other');
header('Content-Type: application/json');

I don't think that one is better than the other in general; it depends on how you intend to use it.

• If you want to store it in a DB column that has a charset/collation that does not support the right single quote character, you may run into storing it as the multi-byte character instead of 7-bit ASCII (’).
• If you are displaying it on an html element that specifies a charset that does not support it, it may not display in either case.
• If many developers are going to be editing/viewing this file with editors/keyboards that do not support properly typing or displaying the character, you may want to use the entity
• If you need to convert the file between various character encodings or formats, you may want to use the entity
• If your HTML code may escape entities improperly, you may want to use the character.

In general I would lean more towards using the character because as you point out it is easier to read and type.

                if (drawables[i] instanceof ScaleDrawable) {
                    drawables[i].setLevel(1);
                }
                drawables[i].setBounds(0, 0, (int) (drawables[i].getIntrinsicWidth() * fitFactor),

In Java, the equals() method that is inherited from Object is:

public boolean equals(Object other);

In other words, the parameter must be of type Object. This is called overriding; your method public boolean equals(Book other) does what is called overloading to the equals() method.

The ArrayList uses overridden equals() methods to compare contents (e.g. for its contains() and equals() methods), not overloaded ones. In most of your code, calling the one that didn't properly override Object's equals was fine, but not compatible with ArrayList.

So, not overriding the method correctly can cause problems.

I override equals the following everytime:

@Override
public boolean equals(Object other){
    if (other == null) return false;
    if (other == this) return true;
    if (!(other instanceof MyClass)) return false;
    MyClass otherMyClass = (MyClass)other;
    ...test other properties here...
}

The use of the @Override annotation can help a ton with silly mistakes.

Use it whenever you think you are overriding a super class' or interface's method. That way, if you do it the wrong way, you will get a compile error.

Godaddy Installation Tips

When you restart udev, kill adb server & start adb server goto android sdk installation path & do all on sudo. then run adb devices it will solve permission problem.

if ( $("#your_select_id option[value=<enter_value_here>]").length == 0 ){
  alert("option doesn't exist!");

I have taken my example from a couple different websites on google. I have tested this on ff 5.0, IE 8.0, and Chrome 10. It works on all of them.

I have got similar issue which data retrieved from .xlsx file. Unfortunately, I could not find the proper answer here. I handled it on my own with dplyr as below which might help others:

#install.packages("xlsx")
library(xlsx)
extracted_df <- read.xlsx("test.xlsx", sheetName='Sheet1', stringsAsFactors=FALSE)
# Replace all NAs in a data frame with "G" character
extracted_df[is.na(extracted_df)] <- "G"

However, I could not handle it with the readxl package which does not have similar parameter to the stringsAsFactors. For the reason, I have moved to the xlsx package.

EditPad Pro and PowerGREP have a unique feature that allows you to change the case of the backreference. \U1 inserts the first backreference in uppercase, \L1 in lowercase and \F1 with the first character in uppercase and the remainder in lowercase. Finally, \I1 inserts it with the first letter of each word capitalized, and the other letters in lowercase.

The current answers did not solve the problem for me, because I had node installed in /usr/bin/node and /usr/local/bin/node - so the system always resolved these first, and ignored the nvm version.

I solved the issue by moving the existing versions to /usr/bin/node-system and /usr/local/bin/node-system

Then I had no node command anymore, until I used nvm use :(

I solved this issue by creating a symlink to the version that would be installed by nvm.

sudo mv /usr/local/bin/node /usr/local/bin/node-system    
sudo mv /usr/bin/node /usr/bin/node-system 
nvm use node
  Now using node v12.20.1 (npm v6.14.10)
which node
  /home/paul/.nvm/versions/node/v12.20.1/bin/node
sudo ln -s /home/paul/.nvm/versions/node/v12.20.1/bin/node /usr/bin/node

Then open a new shell

node -v
  v12.20.1

I was using the Font Awesome library and was able to achieve this affect by tacking on the following to any html element.

<div class="fa fa-rotate-270">
  My Test Text
</div>

Your mileage may vary.

A single regular expression replace should do it:

var stringWithSmallIntegers = "4° 7' 34"W, 168° 1' 23"N";

var paddedString = stringWithSmallIntegers.replace(
    /\d+/g,
    function pad(digits) {
        return digits.length === 1 ? '0' + digits : digits;
    });

alert(paddedString);

shows the expected output.

$total_ratings is an array.

It is not possible with CSS, however you could do this with jQuery.

JSFIDDLE DEMO

jQuery:

$('li').not(':hidden').last().addClass("red");

HTML:

<ul>
        <li>Item 1</li>
        <li>Item 2</li>
        <li>Item 3</li>
        <li class="hideme">Item 4</li>    
</ul>

CSS:

.hideme {
    display:none;
}

.red {
    color: red;
}

jQuery (previous solution):

var $items = $($("li").get().reverse());

$items.each(function() {

    if ($(this).css("display") != "none") {
        $(this).addClass("red");
        return false;
    }

});

Example downloader class without Alamofire:

class Downloader {
    class func load(URL: NSURL) {
        let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
        let session = NSURLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil)
        let request = NSMutableURLRequest(URL: URL)
        request.HTTPMethod = "GET"
        let task = session.dataTaskWithRequest(request, completionHandler: { (data: NSData!, response: NSURLResponse!, error: NSError!) -> Void in
            if (error == nil) {
                // Success
                let statusCode = (response as NSHTTPURLResponse).statusCode
                println("Success: \(statusCode)")

                // This is your file-variable:
                // data
            }
            else {
                // Failure
                println("Failure: %@", error.localizedDescription);
            }
        })
        task.resume()
    }
}

This is how to use it in your own code:

class Foo {
    func bar() {
        if var URL = NSURL(string: "http://www.mywebsite.com/myfile.pdf") {
            Downloader.load(URL)
        }
    }
}

Swift 3 Version

Also note to download large files on disk instead instead in memory. see `downloadTask:

class Downloader {
    class func load(url: URL, to localUrl: URL, completion: @escaping () -> ()) {
        let sessionConfig = URLSessionConfiguration.default
        let session = URLSession(configuration: sessionConfig)
        let request = try! URLRequest(url: url, method: .get)

        let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
            if let tempLocalUrl = tempLocalUrl, error == nil {
                // Success
                if let statusCode = (response as? HTTPURLResponse)?.statusCode {
                    print("Success: \(statusCode)")
                }

                do {
                    try FileManager.default.copyItem(at: tempLocalUrl, to: localUrl)
                    completion()
                } catch (let writeError) {
                    print("error writing file \(localUrl) : \(writeError)")
                }

            } else {
                print("Failure: %@", error?.localizedDescription);
            }
        }
        task.resume()
    }
}

Another reason this can happen:

The component you are using formControl in is not declared in a module that imports the ReactiveFormsModule.

So check the module that declares the component that throws this error.

BE VERY CAREFUL, the problem may come from multibytes encoding and inappropriate PHP functions used...

It was the case for me and it took me a while to figure it out.

For example, I get the a string from MySQL using utf8mb4 (very common now to encode emojis):

$formattedString = strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WILL RETURN THE ERROR 'Detected an illegal character in input string'

The problem does not stand in iconv() but stands in strtolower() in this case.

The appropriate way is to use Multibyte String Functions mb_strtolower() instead of strtolower()

$formattedString = mb_strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WORK FINE

When using Rails 5 (currently still in beta), there's a new method, parsed_body on the test response, which will return the response parsed as what the last request was encoded at.

If it's a local development tomcat launched from IDE, then restarting this IDE and rebuild project also helps.

Update:

You could also try to find if there is any running tomcat process in the background and kill it.

I have MySQL schema with autogen values. I use strategy=GenerationType.IDENTITY tag and seems to work fine in MySQL I guess it should work most db engines as well.

CREATE TABLE user (
    id bigint NOT NULL auto_increment,
    name varchar(64) NOT NULL default '',
    PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

User.java:

// mark this JavaBean to be JPA scoped class
@Entity
@Table(name="user")
public class User {
    @Id @GeneratedValue(strategy=GenerationType.IDENTITY)
    private long id;    // primary key (autogen surrogate)

    @Column(name="name")
    private String name;

    public long getId() { return id; }
    public void setId(long id) { this.id = id; }

    public String getName() { return name; }
    public void setName(String name) { this.name=name; }
}

You may want to append it as a string?

import datetime 
mylist = [] 
today = str(datetime.date.today())
mylist.append(today) 
print mylist

This has been asked so many times so that a user with over 1000 points ask for this is some strange
But just to show just another way to do it:

echo "/some/random/file.csv:some string" | awk '{sub(/:.*/,x)}1'
/some/random/file.csv

You can easily do that with a for loop,

public static void main(String[] args) {
  String aToZ="ABCD.....1234"; // 36 letter.
  String randomStr=generateRandom(aToZ);

}

private static String generateRandom(String aToZ) {
    Random rand=new Random();
    StringBuilder res=new StringBuilder();
    for (int i = 0; i < 17; i++) {
       int randIndex=rand.nextInt(aToZ.length()); 
       res.append(aToZ.charAt(randIndex));            
    }
    return res.toString();
}

Yes, you can pass predicate to sort. That would be your reverse implementation.

I wrote this answer about four years ago and my opinion hasn't changed. But since then there have been significant developments on the micro-services front. I added micro-services specific notes at the end...

I'll weigh in against the idea, with real-world experience to back up my vote.

I was brought on to a large application that had five contexts for a single database. In the end, we ended up removing all of the contexts except for one - reverting back to a single context.

At first the idea of multiple contexts seems like a good idea. We can separate our data access into domains and provide several clean lightweight contexts. Sounds like DDD, right? This would simplify our data access. Another argument is for performance in that we only access the context that we need.

But in practice, as our application grew, many of our tables shared relationships across our various contexts. For example, queries to table A in context 1 also required joining table B in context 2.

This left us with a couple poor choices. We could duplicate the tables in the various contexts. We tried this. This created several mapping problems including an EF constraint that requires each entity to have a unique name. So we ended up with entities named Person1 and Person2 in the different contexts. One could argue this was poor design on our part, but despite our best efforts, this is how our application actually grew in the real world.

We also tried querying both contexts to get the data we needed. For example, our business logic would query half of what it needed from context 1 and the other half from context 2. This had some major issues. Instead of performing one query against a single context, we had to perform multiple queries across different contexts. This has a real performance penalty.

In the end, the good news is that it was easy to strip out the multiple contexts. The context is intended to be a lightweight object. So I don't think performance is a good argument for multiple contexts. In almost all cases, I believe a single context is simpler, less complex, and will likely perform better, and you won't have to implement a bunch of work-arounds to get it to work.

I thought of one situation where multiple contexts could be useful. A separate context could be used to fix a physical issue with the database in which it actually contains more than one domain. Ideally, a context would be one-to-one to a domain, which would be one-to-one to a database. In other words, if a set of tables are in no way related to the other tables in a given database, they should probably be pulled out into a separate database. I realize this isn't always practical. But if a set of tables are so different that you would feel comfortable separating them into a separate database (but you choose not to) then I could see the case for using a separate context, but only because there are actually two separate domains.

Regarding micro-services, one single context still makes sense. However, for micro-services, each service would have its own context which includes only the database tables relevant to that service. In other words, if service x accesses tables 1 and 2, and service y accesses tables 3 and 4, each service would have its own unique context which includes tables specific to that service.

I'm interested in your thoughts.

Put your JTable inside a JScrollPane. Try this:

add(new JScrollPane(scrTbl));

You can change it by going File => Settings (Shortcut CTRL+ ALT+ S) , from Left panel Choose Appearance , Now from Right Panel choose theme.

Android Studio 2.1

Preference -> Search for Appearance -> UI options , Click on DropDown Theme

Android 2.2

Android studio -> File -> Settings -> Appearance & Behavior -> Look for UI Options

EDIT :

Import External Themes

You can download custom theme from this website. Choose your theme, download it. To set theme Go to Android studio -> File -> Import Settings -> Choose the .jar file downloaded.

For AMPPS, I have to add this is my phpMyAdmin/config.inc.php

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

Note: In Ubuntu, I had to locate where the file is and I used locate config.inc.php

This function should work as expected

function Get_User_Ip()
{
    $IP = false;
    if (getenv('HTTP_CLIENT_IP'))
    {
        $IP = getenv('HTTP_CLIENT_IP');
    }
    else if(getenv('HTTP_X_FORWARDED_FOR'))
    {
        $IP = getenv('HTTP_X_FORWARDED_FOR');
    }
    else if(getenv('HTTP_X_FORWARDED'))
    {
        $IP = getenv('HTTP_X_FORWARDED');
    }
    else if(getenv('HTTP_FORWARDED_FOR'))
    {
        $IP = getenv('HTTP_FORWARDED_FOR');
    }
    else if(getenv('HTTP_FORWARDED'))
    {
        $IP = getenv('HTTP_FORWARDED');
    }
    else if(getenv('REMOTE_ADDR'))
    {
        $IP = getenv('REMOTE_ADDR');
    }

    //If HTTP_X_FORWARDED_FOR == server ip
    if((($IP) && ($IP == getenv('SERVER_ADDR')) && (getenv('REMOTE_ADDR')) || (!filter_var($IP, FILTER_VALIDATE_IP))))
    {
        $IP = getenv('REMOTE_ADDR');
    }

    if($IP)
    {
        if(!filter_var($IP, FILTER_VALIDATE_IP))
        {
            $IP = false;
        }
    }
    else
    {
        $IP = false;
    }
    return $IP;
}

You can use the .charAt(int) function with Strings to retrieve the char value at any index. If you want to convert the String to a char array, try calling .toCharArray() on the String. If the string is 1 character long, just take that character by calling .charAt(0) (or .First() in C#).

string textboxID;
string da;
textboxID = "ctl00$MainContent$grd$ctl" + (grd.Columns.Count + j).ToString() + "$txtDyna" + (k).ToString();
textboxID= ctl00$MainContent$grd$ctl12$ctl00;
da = Request.Form(textboxID);

The real confusion here is not about parse vs stringify, it's about the data type of the data parameter of the success callback.

data can be either the raw response, i.e a string, or it can be an JavaScript object, as per the documentation:

success

Type: Function( Anything data, String textStatus, jqXHR jqXHR ) A function to be called if the request succeeds. The function gets passed three arguments: The data returned from the server, formatted according to the dataType parameter or the dataFilter callback function, if specified;<..>

And the dataType defaults to a setting of 'intelligent guess'

dataType (default: Intelligent Guess (xml, json, script, or html))

Type: String The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).

This is a tricky but super simple solution which works in many situations:

import os
os.system('sample_cmd > tmp')
print open('tmp', 'r').read()

A temporary file(here is tmp) is created with the output of the command and you can read from it your desired output.

Extra note from the comments: You can remove the tmp file in the case of one-time job. If you need to do this several times, there is no need to delete the tmp.

os.remove('tmp')

Unless you are subtracting dates on same browser client and don't care about edge cases like day light saving time changes, you are probably better off using moment.js which offers powerful localized APIs. For example, this is what I have in my utils.js:

subtractDates: function(date1, date2) {
    return moment.subtract(date1, date2).milliseconds();
},
millisecondsSince: function(dateSince) {
    return moment().subtract(dateSince).milliseconds();
},

Restarting Visual Studio Code after

resolved the error messages for me.

No you are missing the Python header files. This mostly happens on Linux when you are using the system Python (there are reasons not to do that, but that's a different question).

You probably need to install some package, and it's probably called python-dev or python-devel.

 sudo yum install python-devel

or

 sudo aptitude install python-dev

Or somesuch.

To be sure, you need to not only replace the single quotes, but as well the already escaped ones:

"first ' and \' second".replace(/'|\\'/g, "\\'")

run github that you downloaded, click tools and options symbol(top right), click about github for windows and then open the debug log. under DIAGNOSTICS look for Git Executable Exists:

The geocoder has quota and rate limits. From experience, you can geocode ~10 locations without hitting the query limit (the actual number probably depends on server loading). The best solution is to delay when you get OVER_QUERY_LIMIT errors, then retry. See these similar posts:

• OVER_QUERY_LIMIT in Google Maps API v3: How do I pause/delay in Javascript to slow it down?

• How do I Geocode 20 addresses without receiving an OVER_QUERY_LIMIT response?

UPDATE 7/3/2014: As of now, jquery-latest.js is no longer being updated. From the jQuery blog:

We know that http://code.jquery.com/jquery-latest.js is abused because of the CDN statistics showing it’s the most popular file. That wouldn’t be the case if it was only being used by developers to make a local copy.

We have decided to stop updating this file, as well as the minified copy, keeping both files at version 1.11.1 forever.

The Google CDN team has joined us in this effort to prevent inadvertent web breakage and no longer updates the file at http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js. That file will stay locked at version 1.11.1 as well.

The following, now moot, answer is preserved here for historical reasons.

Don't do this. Seriously, don't.

Linking to major versions of jQuery does work, but it's a bad idea -- whole new features get added and deprecated with each decimal update. If you update jQuery automatically without testing your code COMPLETELY, you risk an unexpected surprise if the API for some critical method has changed.

Here's what you should be doing: write your code using the latest version of jQuery. Test it, debug it, publish it when it's ready for production.

Then, when a new version of jQuery rolls out, ask yourself: Do I need this new version in my code? For instance, is there some critical browser compatibility that didn't exist before, or will it speed up my code in most browsers?

If the answer is "no", don't bother updating your code to the latest jQuery version. Doing so might even add NEW errors to your code which didn't exist before. No responsible developer would automatically include new code from another site without testing it thoroughly.

There's simply no good reason to ALWAYS be using the latest version of jQuery. The old versions are still available on the CDNs, and if they work for your purposes, then why bother replacing them?

A secondary, but possibly more important, issue is caching. Many people link to jQuery on a CDN because many other sites do, and your users have a good chance of having that version already cached.

The problem is, caching only works if you provide a full version number. If you provide a partial version number, far-future caching doesn't happen -- because if it did, some users would get different minor versions of jQuery from the same URL. (Say that the link to 1.7 points to 1.7.1 one day and 1.7.2 the next day. How will the browser make sure it's getting the latest version today? Answer: no caching.)

In fact here's a breakdown of several options and their expiration settings...

http://code.jquery.com/jquery-latest.min.js (no cache)

http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js (1 year)

So, by linking to jQuery this way, you're actually eliminating one of the major reasons to use a CDN in the first place.

http://code.jquery.com/jquery-latest.min.js may not always give you the version you expect, either. As of this writing, it links to the latest version of jQuery 1.x, even though jQuery 2.x has been released as well. This is because jQuery 1.x is compatible with older browsers including IE 6/7/8, and jQuery 2.x is not. If you want the latest version of jQuery 2.x, then (for now) you need to specify that explicitly.

The two versions have the same API, so there is no perceptual difference for compatible browsers. However, jQuery 1.x is a larger download than 2.x.

Object assign copies one or more source objects to the target object. So we could use Object.assign here.

Syntax: Object.assign(target, ...sources)

var obj  = {};_x000D_
_x000D_
Object.assign(obj, {"1":"aa", "2":"bb"})_x000D_
_x000D_
console.log(obj)

Using toIntExact(long value) returns the value of the long argument, throwing an exception if the value overflows an int. it will work only API level 24 or above.

int id = Math.toIntExact(longId);

I believe it would be like this

takedata.match(/(\[.+\])/g);

the g at the end means global, so it doesn't stop at the first match.

Use the to_datetime function, specifying a format to match your data.

raw_data['Mycol'] =  pd.to_datetime(raw_data['Mycol'], format='%d%b%Y:%H:%M:%S.%f')

I used Robert Lee`s answer and it works great! Just writing down the complete function i'm using:

function isMobileDevice(){
    $aMobileUA = array(
        '/iphone/i' => 'iPhone', 
        '/ipod/i' => 'iPod', 
        '/ipad/i' => 'iPad', 
        '/android/i' => 'Android', 
        '/blackberry/i' => 'BlackBerry', 
        '/webos/i' => 'Mobile'
    );

    //Return true if Mobile User Agent is detected
    foreach($aMobileUA as $sMobileKey => $sMobileOS){
        if(preg_match($sMobileKey, $_SERVER['HTTP_USER_AGENT'])){
            return true;
        }
    }
    //Otherwise return false..  
    return false;
}

Using linear algebra, there exist algorithms that achieve better complexity than the naive O(n³). Solvay Strassen algorithm achieves a complexity of O(n^2.807) by reducing the number of multiplications required for each 2x2 sub-matrix from 8 to 7.

The fastest known matrix multiplication algorithm is Coppersmith-Winograd algorithm with a complexity of O(n^2.3737). Unless the matrix is huge, these algorithms do not result in a vast difference in computation time. In practice, it is easier and faster to use parallel algorithms for matrix multiplication.

C++11 added alias declarations, which are generalization of typedef, allowing templates:

template <size_t N>
using Vector = Matrix<N, 1>;

The type Vector<3> is equivalent to Matrix<3, 1>.

In C++03, the closest approximation was:

template <size_t N>
struct Vector
{
    typedef Matrix<N, 1> type;
};

Here, the type Vector<3>::type is equivalent to Matrix<3, 1>.

For MS Access: Launch a hidden form with Me.TimerInterval set and a Form_Timer event handler. Put your to-be-delayed code in the Form_Timer routine - exiting the routine after each execution.

E.g.:

Private Sub Form_Load()
    Me.TimerInterval = 30000 ' 30 sec
End Sub

Private Sub Form_Timer()

    Dim lngTimerInterval  As Long: lngTimerInterval = Me.TimerInterval

    Me.TimerInterval = 0

    '<Your Code goes here>

    Me.TimerInterval = lngTimerInterval
End Sub

"Your Code goes here" will be executed 30 seconds after the form is opened and 30 seconds after each subsequent execution.

Close the hidden form when done.

Crossbrowser and IE >= 11:

document.getElementById("element-id").outerHTML = "";

E-mail addresses are very difficult to verify correctly with a mere regex. Here is a pretty scary regex that supposedly implements RFC822, chapter 6, the specification of valid e-mail addresses.

Not really an answer, but maybe related to what you're trying to accomplish.

I solved it in this way

A pkg-config file describes all necessary compile-time and link-time flags and dependencies needed to use a library.

pkg-config --static --libs glfw3

shows me that

-L/usr/local/lib -lglfw3 -lrt -lXrandr -lXinerama -lXi -lXcursor -lGL -lm -ldl -lXrender -ldrm -lXdamage -lX11-xcb -lxcb-glx -lxcb-dri2 -lxcb-dri3 -lxcb-present -lxcb-sync -lxshmfence -lXxf86vm -lXfixes -lXext -lX11 -lpthread -lxcb -lXau -lXdmcp  

I don't know if all these libs are actually necessary for compiling but for me it works...
