The ARM architecture was originally designed for Acorn personal computers (See Acorn Archimedes, circa 1987, and RiscPC), which were just as much keyboard-based personal computers as were x86 based IBM PC models. Only later ARM implementations were primarily targeted at the mobile and embedded market segment.

Originally, simple RISC CPUs of roughly equivalent performance could be designed by much smaller engineering teams (see Berkeley RISC) than those working on the x86 development at Intel.

But, nowadays, the fastest ARM chips have very complex multi-issue out-of-order instruction dispatch units designed by large engineering teams, and x86 cores may have something like a RISC core fed by an instruction translation unit.

So, any current differences between the two architectures are more related to the specific market needs of the product niches that the development teams are targeting. (Random opinion: ARM probably makes more in license fees from embedded applications that tend to be far more power and cost constrained. And Intel needs to maintain a performance edge in PCs and servers for their profit margins. Thus you see differing implementation optimizations.)

How tightly coupled are your tasks?

If they can live independently of each other, then use processes. If they rely on each other, then use threads. That way you can kill and restart a bad process without interfering with the operation of the other tasks.

@Bhabadyuti Bal give us a good answer, in gradle you can use :

compile 'org.springframework.boot:spring-boot-starter-data-jpa' 
compile 'com.h2database:h2'

in test time :

testCompile 'org.reactivecommons.utils:object-mapper:0.1.0'
testCompile 'com.h2database:h2'

For Amazon AWS ECS/ECR, you should manage your environment variables (especially secrets) via a private S3 bucket. See blog post How to Manage Secrets for Amazon EC2 Container Service–Based Applications by Using Amazon S3 and Docker.

You can't use $(this) since jQuery doesn't know what it is there. You seem to be overcomplicating things. You can do $('#content h1.aktiv').hide(). There's no reason to test to see if the class exists.

Why must it work?

The JLS 5, Section 15.18.1.1 JLS 8 § 15.18.1 "String Concatenation Operator +", leading to JLS 8, § 5.1.11 "String Conversion", requires this operation to succeed without failure:

...Now only reference values need to be considered. If the reference is null, it is converted to the string "null" (four ASCII characters n, u, l, l). Otherwise, the conversion is performed as if by an invocation of the toString method of the referenced object with no arguments; but if the result of invoking the toString method is null, then the string "null" is used instead.

How does it work?

Let's look at the bytecode! The compiler takes your code:

String s = null;
s = s + "hello";
System.out.println(s); // prints "nullhello"

and compiles it into bytecode as if you had instead written this:

String s = null;
s = new StringBuilder(String.valueOf(s)).append("hello").toString();
System.out.println(s); // prints "nullhello"

(You can do so yourself by using javap -c)

The append methods of StringBuilder all handle null just fine. In this case because null is the first argument, String.valueOf() is invoked instead since StringBuilder does not have a constructor that takes any arbitrary reference type.

If you were to have done s = "hello" + s instead, the equivalent code would be:

s = new StringBuilder("hello").append(s).toString();

where in this case the append method takes the null and then delegates it to String.valueOf().

Note: String concatenation is actually one of the rare places where the compiler gets to decide which optimization(s) to perform. As such, the "exact equivalent" code may differ from compiler to compiler. This optimization is allowed by JLS, Section 15.18.1.2:

To increase the performance of repeated string concatenation, a Java compiler may use the StringBuffer class or a similar technique to reduce the number of intermediate String objects that are created by evaluation of an expression.

The compiler I used to determine the "equivalent code" above was Eclipse's compiler, ecj.

Use -1 as the start position:

INSTR('JD-EQ-0001', '-', -1)

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

Have you tried the uncurl package (https://github.com/spulec/uncurl)? You can install it via pip, pip install uncurl. Your curl request returns:

>>> uncurl "curl --header \"Authorization:access_token myToken\" https://website.com/id"

requests.get("https://website.com/id",
    headers={
        "Authorization": "access_token myToken"
    },
    cookies={},
)

Do not forget to exclude carriage returns from your data !!!

as in:

SELECT 
  Myotherval
  , CASE WHEN TRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '%[^0-9]%' and RTRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '.' and isnumeric(REPLACE([MyVal], char(13) + char(10), '')) = 1 THEN 'my number: ' +  [MyVal]
             ELSE ISNULL(Cast([MyVal] AS VARCHAR(8000)), '')
        END AS 'MyVal'
FROM MyTable

This answer is deprecated, please see @ankitjaininfo's answer below for a more modern solution

Here's how I think you make a POST request with data and a cookie using just the node http library. This example is posting JSON, set your content-type and content-length accordingly if you post different data.

// NB:- node's http client API has changed since this was written
// this code is for 0.4.x
// for 0.6.5+ see http://nodejs.org/docs/v0.6.5/api/http.html#http.request

var http = require('http');

var data = JSON.stringify({ 'important': 'data' });
var cookie = 'something=anything'

var client = http.createClient(80, 'www.example.com');

var headers = {
    'Host': 'www.example.com',
    'Cookie': cookie,
    'Content-Type': 'application/json',
    'Content-Length': Buffer.byteLength(data,'utf8')
};

var request = client.request('POST', '/', headers);

// listening to the response is optional, I suppose
request.on('response', function(response) {
  response.on('data', function(chunk) {
    // do what you do
  });
  response.on('end', function() {
    // do what you do
  });
});
// you'd also want to listen for errors in production

request.write(data);

request.end();

What you send in the Cookie value should really depend on what you received from the server. Wikipedia's write-up of this stuff is pretty good: http://en.wikipedia.org/wiki/HTTP_cookie#Cookie_attributes

The selected answer did not work in my Web API application. I had to use

System.Web.HttpRuntime.AppDomainAppPath

Nishant provided a good solution, but there's an easier way. Simply mark the desired fields with the @Expose annotation, such as:

@Expose private Long id;

Leave out any fields that you do not want to serialize. Then just create your Gson object this way:

Gson gson = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create();

If you created ImageView from Java Class

ImageView img = new ImageView(this);

//Here we are setting the image in image view
img.setImageResource(R.drawable.my_image);

A much shorter version for getting a list of all subclasses:

from itertools import chain

def subclasses(cls):
    return list(
        chain.from_iterable(
            [list(chain.from_iterable([[x], subclasses(x)])) for x in cls.__subclasses__()]
        )
    )

I think in certain cases, you can create a FAKE "list" of items in the database, for example, the merchandise has a few pictures to show its details, you can concatenate all the IDs of pictures split by comma and store the string into the DB, then you just need to parse the string when you need it. I am working on a website now and I am planning to use this way.

here's an example for bash:

usage="$(basename "$0") [-h] [-s n] -- program to calculate the answer to life, the universe and everything

where:
    -h  show this help text
    -s  set the seed value (default: 42)"

seed=42
while getopts ':hs:' option; do
  case "$option" in
    h) echo "$usage"
       exit
       ;;
    s) seed=$OPTARG
       ;;
    :) printf "missing argument for -%s\n" "$OPTARG" >&2
       echo "$usage" >&2
       exit 1
       ;;
   \?) printf "illegal option: -%s\n" "$OPTARG" >&2
       echo "$usage" >&2
       exit 1
       ;;
  esac
done
shift $((OPTIND - 1))

To use this inside a function:

• use "$FUNCNAME" instead of $(basename "$0")
• add local OPTIND OPTARG before calling getopts

import threading 

# global variable x 
x = 0

def increment(): 
    """ 
    function to increment global variable x 
    """
    global x 
    x += 1

def thread_task(): 
    """ 
    task for thread 
    calls increment function 100000 times. 
    """
    for _ in range(100000): 
        increment() 

def main_task(): 
    global x 
    # setting global variable x as 0 
    x = 0

    # creating threads 
    t1 = threading.Thread(target=thread_task) 
    t2 = threading.Thread(target=thread_task) 

    # start threads 
    t1.start() 
    t2.start() 

    # wait until threads finish their job 
    t1.join() 
    t2.join() 

if __name__ == "__main__": 
    for i in range(10): 
        main_task() 
        print("Iteration {0}: x = {1}".format(i,x))

you can use call back function, like this

  $this->form_validation->set_rules('userfile', 'Document', 'callback_file_selected_test');

    if ($this->form_validation->run() == FALSE) {
         //error
     }
    else{
           // success       
      }

function file_selected_test(){

    $this->form_validation->set_message('file_selected_test', 'Please select file.');
    if (empty($_FILES['userfile']['name'])) {
            return false;
        }else{
            return true;
        }
}

What is a when you call Ancestors('A',a)? If a['A'] is None, or if a['A'][0] is None, you'd receive that exception.

The best answer is to add a Resources/.gitignore file under Resources containing:

# Ignore any file in this directory except for this file and *.foo files
*
!/.gitignore
!*.foo

If you are unwilling or unable to add that .gitignore file, there is an inelegant solution:

# Ignore any file but *.foo under Resources. Update this if we add deeper directories
Resources/*
!Resources/*/
!Resources/*.foo
Resources/*/*
!Resources/*/*/
!Resources/*/*.foo
Resources/*/*/*
!Resources/*/*/*/
!Resources/*/*/*.foo
Resources/*/*/*/*
!Resources/*/*/*/*/
!Resources/*/*/*/*.foo

You will need to edit that pattern if you add directories deeper than specified.

Here is a post where someone got it to work. It looks like it requires a registry change.

<h1><span style="font-weight:bold;">THIS IS</span> A HEADLINE</h1>

But be sure that h1 is marked with

font-weight:normal;

You can also set the style with a id or class attribute.

Here is a more comprehensive method that can also accept full month names

def month_string_to_number(string):
    m = {
        'jan': 1,
        'feb': 2,
        'mar': 3,
        'apr':4,
         'may':5,
         'jun':6,
         'jul':7,
         'aug':8,
         'sep':9,
         'oct':10,
         'nov':11,
         'dec':12
        }
    s = string.strip()[:3].lower()

    try:
        out = m[s]
        return out
    except:
        raise ValueError('Not a month')

example:

>>> month_string_to_number("October")
10 
>>> month_string_to_number("oct")
10

Replace the username and password with Integrated Security=SSPI;

   connectionString="data source=localhost;
   initial catalog=northwind;persist security info=True; 
   Integrated Security=SSPI;" 
   providerName="System.Data.SqlClient" /> 
</connectionStrings>

I noticed this wasn't working with a static-first-then-reverse-proxy setup. Here's what that looks like:

location @app {
  proxy_pass http://localhost:3000$request_uri;
}

location / {
  try_files $uri $uri/ @app;
  error_page 405 @app;
}

I use

Object.entries(GoalProgressMeasurement).filter(e => !isNaN(e[0]as any)).map(e => ({ name: e[1], id: e[0] }));

A simple 1 line that does the job.

It does the job in 3 simple steps
- Loads the combination of keys & values using Object.entries.
- Filters out the non numbers (since typescript generates the values for reverse lookup).
- Then we map it to the array object we like.

isocalendar() returns incorrect year and weeknumber values for some dates:

>>> import datetime as dt
>>> myDateTime = dt.datetime.strptime("20141229T000000.000Z",'%Y%m%dT%H%M%S.%fZ')
>>> yr,weekNumber,weekDay = myDateTime.isocalendar()
>>> print "Year is " + str(yr) + ", weekNumber is " + str(weekNumber)
Year is 2015, weekNumber is 1

Compare with Mark Ransom's approach:

>>> yr = myDateTime.year
>>> weekNumber = ((myDateTime - dt.datetime(yr,1,1)).days/7) + 1
>>> print "Year is " + str(yr) + ", weekNumber is " + str(weekNumber)
Year is 2014, weekNumber is 52

IE displays a active x warning and ask for permission if you allow it to run or not. To overcome this the only solution is to;

1. Open Internet Explorer.
2. Click the Tools menu, and then click Internet Options.
3. On the Security tab, click the Custom level button.
4. Scroll down the Security Settings list until you see ActiveX controls and plug-ins.
5. For Automatic prompting for ActiveX controls, click Enable.
6. Scroll down to Download signed ActiveX controls and click Enable or Prompt.
7. Scroll down to Run ActiveX controls and plug-ins and click Enable or Prompt.
8. Scroll down to Script ActiveX controls marked safe for scripting and click Enable or Prompt.
9. Click OK, and then click OK again.

There is no way to overcome this issue except changing manually Internet explorer settings. Try checking if plugin works fine while changed settings. If its still not working or not showing any warning is display try checking console for other errors which are not related to active x. Good luck!

To avoid memory leaks you may use smart pointers whenever you can. There are basically 2 different types of smart pointers in C++

• Reference counted (e.g. boost::shared_ptr / std::tr1:shared_ptr)
• non reference counted (e.g. boost::scoped_ptr / std::auto_ptr)

The main difference is that reference counted smart pointers can be copied (and used in std:: containers) while scoped_ptr cannot. Non reference counted pointers have almost no overhead or no overhead at all. Reference counting always introduces some kind of overhead.

(I suggest to avoid auto_ptr, it has some serious flaws if used incorrectly)

You can solve this issue be adding max-width:

#element {
   width: 100vw;
   height: 100vw;
   max-width: 100%;
}

When you using CSS to make the wrapper full width using the code width: 100vw; then you will notice a horizontal scroll in the page, and that happened because the padding and margin of html and body tags added to the wrapper size, so the solution is to add max-width: 100%

Add in your application.properties file:

#first db

spring.datasource.username = [username]
spring.datasource.password = [password]
spring.datasource.driverClassName = oracle.jdbc.OracleDriver

#second db ...
spring.secondDatasource.url = [url]
spring.secondDatasource.username = [username]
spring.secondDatasource.password = [password]
spring.secondDatasource.driverClassName = oracle.jdbc.OracleDriver

EOF indicates "end of file". A newline (which is what happens when you press enter) isn't the end of a file, it's the end of a line, so a newline doesn't terminate this loop.

The code isn't wrong[*], it just doesn't do what you seem to expect. It reads to the end of the input, but you seem to want to read only to the end of a line.

The value of EOF is -1 because it has to be different from any return value from getchar that is an actual character. So getchar returns any character value as an unsigned char, converted to int, which will therefore be non-negative.

If you're typing at the terminal and you want to provoke an end-of-file, use CTRL-D (unix-style systems) or CTRL-Z (Windows). Then after all the input has been read, getchar() will return EOF, and hence getchar() != EOF will be false, and the loop will terminate.

[*] well, it has undefined behavior if the input is more than LONG_MAX characters due to integer overflow, but we can probably forgive that in a simple example.

The persistence.xml has a jar-file that you can use. From the Java EE 5 tutorial:

<persistence>
    <persistence-unit name="OrderManagement">
        <description>This unit manages orders and customers.
            It does not rely on any vendor-specific features and can
            therefore be deployed to any persistence provider.
        </description>
        <jta-data-source>jdbc/MyOrderDB</jta-data-source>
        <jar-file>MyOrderApp.jar</jar-file>
        <class>com.widgets.Order</class>
        <class>com.widgets.Customer</class>
    </persistence-unit>
</persistence>

This file defines a persistence unit named OrderManagement, which uses a JTA-aware data source jdbc/MyOrderDB. The jar-file and class elements specify managed persistence classes: entity classes, embeddable classes, and mapped superclasses. The jar-file element specifies JAR files that are visible to the packaged persistence unit that contain managed persistence classes, while the class element explicitly names managed persistence classes.

In the case of Hibernate, have a look at the Chapter2. Setup and configuration too for more details.

EDIT: Actually, If you don't mind not being spec compliant, Hibernate supports auto-detection even in Java SE. To do so, add the hibernate.archive.autodetection property:

<persistence-unit name="eventractor" transaction-type="RESOURCE_LOCAL">
  <!-- This is required to be spec compliant, Hibernate however supports
       auto-detection even in JSE.
  <class>pl.michalmech.eventractor.domain.User</class>
  <class>pl.michalmech.eventractor.domain.Address</class>
  <class>pl.michalmech.eventractor.domain.City</class>
  <class>pl.michalmech.eventractor.domain.Country</class>
   -->

  <properties>
    <!-- Scan for annotated classes and Hibernate mapping XML files -->
    <property name="hibernate.archive.autodetection" value="class, hbm"/>

    <property name="hibernate.hbm2ddl.auto" value="validate" />
    <property name="hibernate.show_sql" value="true" />

Avoid the Date object creation w/ System.currentTimeMillis(). A divide by 1000 gets you to Unix epoch.

As mentioned in a comment, you typically want a primitive long (lower-case-l long) not a boxed object long (capital-L Long) for the unixTime variable's type.

long unixTime = System.currentTimeMillis() / 1000L;

All objects in JavaScript are implemented as hashtables/associative arrays. So, the following are the equivalent:

alert(myObj["SomeProperty"]);
alert(myObj.SomeProperty);

And, as already indicated, you "remove" a property from an object via the delete keyword, which you can use in two ways:

delete myObj["SomeProperty"];
delete myObj.SomeProperty;

Open github app. Then, add the Folder of files into the github repo file onto your computer (You WILL need to copy the repo onto your computer. Most repo files are located in the following directory: C:\Users\USERNAME\Documents\GitHub\REPONAME) Then, in the github app, check our your repo. You can easily commit from there.

a[title="My site"] {
    color: red;
}

This also works with any attribute you want to add for instance:

HTML

<div class="my_class" anything="whatever">My Stuff</div>

CSS

.my_class[anything="whatever"] {
    color: red;
}

See it work at: http://jsfiddle.net/vpYWE/1/

$@ is nearly the same as $*, both meaning "all command line arguments". They are often used to simply pass all arguments to another program (thus forming a wrapper around that other program).

The difference between the two syntaxes shows up when you have an argument with spaces in it (e.g.) and put $@ in double quotes:

wrappedProgram "$@"
# ^^^ this is correct and will hand over all arguments in the way
#     we received them, i. e. as several arguments, each of them
#     containing all the spaces and other uglinesses they have.
wrappedProgram "$*"
# ^^^ this will hand over exactly one argument, containing all
#     original arguments, separated by single spaces.
wrappedProgram $*
# ^^^ this will join all arguments by single spaces as well and
#     will then split the string as the shell does on the command
#     line, thus it will split an argument containing spaces into
#     several arguments.

Example: Calling

wrapper "one two    three" four five "six seven"

will result in:

"$@": wrappedProgram "one two    three" four five "six seven"
"$*": wrappedProgram "one two    three four five six seven"
                             ^^^^ These spaces are part of the first
                                  argument and are not changed.
$*:   wrappedProgram one two three four five six seven

Angularjs $http wrap base on XMLHttpRequest. As long as at the header content set following code will do.

"Content-Type": "text/xml; charset=utf-8"

For example:

function callSoap(){
var url = "http://www.webservicex.com/stockquote.asmx";
var soapXml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://www.webserviceX.NET/\"> "+
         "<soapenv:Header/> "+
         "<soapenv:Body> "+
         "<web:GetQuote> "+
         "<web:symbol></web:symbol> "+
         "</web:GetQuote> "+
         "</soapenv:Body> "+
         "</soapenv:Envelope> ";

    return $http({
          url: url,  
          method: "POST",  
          data: soapXml,  
          headers: {  
              "Content-Type": "text/xml; charset=utf-8"
          }  
      })
      .then(callSoapComplete)
      .catch(function(message){
         return message;
      });

    function callSoapComplete(data, status, headers, config) {
        // Convert to JSON Ojbect from xml
        // var x2js = new X2JS();
        // var str2json = x2js.xml_str2json(data.data);
        // return str2json;
        return data.data;

    }

}

You can use the IPython.display.clear_output to clear the output as mentioned in cel's answer. I would add that for me the best solution was to use this combination of parameters to print without any "shakiness" of the notebook:

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print(i, flush=True)

Python doesn't have such types as you describe. There are two types used to represent integral values: int, which corresponds to platform's int type in C, and long, which is an arbitrary precision integer (i.e. it grows as needed and doesn't have an upper limit). ints are silently converted to long if an expression produces result which cannot be stored in int.

You can use the following. They all wrap the window object into a jQuery object.

Load:

$(window).load(function () {
    topInViewport($("#mydivname"))
});

Resize:

$(window).resize(function () {
   topInViewport($("#mydivname"))
});

Scroll

$(window).scroll(function () {
    topInViewport($("#mydivname"))
});

Or bind to them all using on:

$(window).on("load resize scroll",function(e){
    topInViewport($("#mydivname"))
});

If the data is populated from the database, you might consider not using an <input> tag to display it. Nevertheless, you can disable it right in the tag:

<input type='text' value='${magic.database.value}' disabled>

If you need to disable it with Javascript later, you can set the "disabled" attribute:

document.getElementById('theInput').disabled = true;

The reason I suggest not showing the value as an <input> is that, in my experience, it causes layout issues. If the text is long, then in an <input> the user will need to try and scroll the text, which is not something normal people would guess to do. If you just drop it into a <span> or something, you have more styling flexibility.

reference here

!== is the strict not equal operator and only returns a value of true if both the operands are not equal and/or not of the same type. The following examples return a Boolean true:

a !== b 
a !== "2" 
4 !== '4' 

If the were checked as plugin-projects, than you just need to check them out. But do not select the "trunk"(for example) to speed it up. You must select all the projects you want to check out and proceed. Eclipse will than recognize them as such.

For IE8 & IE9 you need to use XDomainRequest (XDR). If you look below you'll see it's in a sort of similar formatting as $.ajax. As far as my research has got me I can't get this cross-domain working in IE6 & 7 (still looking for a work-around for this). XDR first came out in IE8 (it's in IE9 also). So basically first, I test for 6/7 and do no AJAX.

IE10+ is able to do cross-domain normally like all the other browsers (congrats Microsoft... sigh)

After that the else if tests for 'XDomainRequest in window (apparently better than browser sniffing) and does the JSON AJAX request that way, other wise the ELSE does it normally with $.ajax.

Hope this helps!! Took me forever to get this all figured out originally

Information on the XDomainRequest object

// call with your url (with parameters) 
// 2nd param is your callback function (which will be passed the json DATA back)

crossDomainAjax('http://www.somecrossdomaincall.com/?blah=123', function (data) {
    // success logic
});

function crossDomainAjax (url, successCallback) {

    // IE8 & 9 only Cross domain JSON GET request
    if ('XDomainRequest' in window && window.XDomainRequest !== null) {

        var xdr = new XDomainRequest(); // Use Microsoft XDR
        xdr.open('get', url);
        xdr.onload = function () {
            var dom  = new ActiveXObject('Microsoft.XMLDOM'),
                JSON = $.parseJSON(xdr.responseText);

            dom.async = false;

            if (JSON == null || typeof (JSON) == 'undefined') {
                JSON = $.parseJSON(data.firstChild.textContent);
            }

            successCallback(JSON); // internal function
        };

        xdr.onerror = function() {
            _result = false;  
        };

        xdr.send();
    } 

    // IE7 and lower can't do cross domain
    else if (navigator.userAgent.indexOf('MSIE') != -1 &&
             parseInt(navigator.userAgent.match(/MSIE ([\d.]+)/)[1], 10) < 8) {
       return false;
    }    

    // Do normal jQuery AJAX for everything else          
    else {
        $.ajax({
            url: url,
            cache: false,
            dataType: 'json',
            type: 'GET',
            async: false, // must be set to false
            success: function (data, success) {
                successCallback(data);
            }
        });
    }
}

The correct way to change directories is actually with process.chdir(directory). Here's an example from the documentation:

console.log('Starting directory: ' + process.cwd());
try {
  process.chdir('/tmp');
  console.log('New directory: ' + process.cwd());
}
catch (err) {
  console.log('chdir: ' + err);
}

This is also testable in the Node.js REPL:

[monitor@s2 ~]$ node
> process.cwd()
'/home/monitor'
> process.chdir('../');
undefined
> process.cwd();
'/home'

i think this method will help you to find out is keybord is visible or not.

 public Boolean isSoftKeyBoardVisible(){
    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);

    if (imm.isAcceptingText()) {
        Log.d(TAG,"Software Keyboard was shown");
        return true;
    } else {
        Log.d(TAG,"Software Keyboard was not shown");
        return false;
    }

}

Sorry, I solved my problem with the code above:

$("#captureImage").live("change", function() {
    if($("#captureImage:checked").val() !== undefined) {
        navigator.device.capture.captureImage(function(mediaFiles) {
            console.log("works");
        }, function(exception) {
            $("#captureImage").removeAttr('checked').checkboxradio('refresh');
            _callback.error(exception);
        }, {});
    }
});

Swift 5

To make it easy, create a file "DispatchQueue+Extensions.swift" with this content :

import Foundation

typealias Dispatch = DispatchQueue

extension Dispatch {

    static func background(_ task: @escaping () -> ()) {
        Dispatch.global(qos: .background).async {
            task()
        }
    }

    static func main(_ task: @escaping () -> ()) {
        Dispatch.main.async {
            task()
        }
    }
}

Usage :

Dispatch.background {
    // do stuff

    Dispatch.main { 
        // update UI
    }
}

(eg: div,footer,table) Right click -> Edit as HTML

Then you can copy and paster wherever you need...

that's all enjoy your coding.....

You can use this code

var stringDate = "2005-07-08T00:00:00+0000";
var dTimezone = new Date();
var offset = dTimezone.getTimezoneOffset() / 60;
var date = new Date(Date.parse(stringDate));
date.setHours(date.getHours() + offset);

You can update your npm to the latest stable version with the following command:

 npm install npm@latest -g

Use PowerShell to run it. This command doesn't need windows administrator privileges and you can verify the result with npm -v

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_profile, container, false);
    notification = (ImageView)v.findViewById(R.id.notification);

    notification.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            FragmentTransaction fr = getFragmentManager().beginTransaction();
            fr.replace(R.id.container,new NotificationFragment());
            fr.commit();
        }
    });

    return v;
}

For latest mac os, Below shortcuts works for me.

The easiest way I've found to create postscripts is the following, using the setEPS() command:

setEPS()
postscript("whatever.eps")
plot(rnorm(100), main="Hey Some Data")
dev.off()

Classic 8-bit LaTeX is very restricted in which UTF8 characters it can use; it's highly dependent on the encoding of the font you're using and which glyphs that font has available.

Since you don't give a specific example, it's hard to know exactly where the problem is — whether you're attempting to use a glyph that your font doesn't have or whether you're not using the correct font encoding in the first place.

Here's a minimal example showing how a few UTF8 characters can be used in a LaTeX document:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\begin{document}
‘Héllø—thêrè.’
\end{document}

You may have more luck with the [utf8x] encoding, but be slightly warned that it's no longer supported and has some idiosyncrasies compared with [utf8] (as far as I recall; it's been a while since I've looked at it). But if it does the trick, that's all that matters for you.

!!! I had a similar problem and I found that in my case the withCredentials: true in the request was activating the CORS check while issuing the same in the header would avoid the check:

https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSMIssingAllowCredentials

do not use withCredentials: true but set 'Access-Control-Allow-Credentials':true in the headers

Also with Apache StringUtils.strip():

 StringUtils.strip(null, *)          = null
 StringUtils.strip("", *)            = ""
 StringUtils.strip("abc", null)      = "abc"
 StringUtils.strip("  abc", null)    = "abc"
 StringUtils.strip("abc  ", null)    = "abc"
 StringUtils.strip(" abc ", null)    = "abc"
 StringUtils.strip("  abcyx", "xyz") = "  abc"

So,

final String SchrodingersQuotedString = "may or may not be quoted";
StringUtils.strip(SchrodingersQuotedString, "\""); //quoted no more

This method works both with quoted and unquoted strings as shown in my example. The only downside is, it will not look for strictly matched quotes, only leading and trailing quote characters (ie. no distinction between "partially and "fully" quoted strings).

import * as fs from 'fs';
import * as path from 'path';

fs.readFile(path.join(__dirname, "filename.txt"), (err, data) => {
    if (err) throw err;
    console.log(data);
})

EDIT:

consider the project structure:

../readfile/
+-- filename.txt
+-- src
    +-- index.js
    +-- index.ts

consider the index.ts:

import * as fs from 'fs';
import * as path from 'path';

function lookFilesInDirectory(path_directory) {
    fs.stat(path_directory, (err, stat) => {
        if (!err) {
            if (stat.isDirectory()) {
                console.log(path_directory)
                fs.readdirSync(path_directory).forEach(file => {
                    console.log(`\t${file}`);
                });
                console.log();
            }
        }
    });
}

let path_view = './';
lookFilesInDirectory(path_view);
lookFilesInDirectory(path.join(__dirname, path_view));

if you have in the readfile folder and run tsc src/index.ts && node src/index.js, the output will be:

./
        filename.txt
        src

/home/andrei/scripts/readfile/src/
        index.js
        index.ts

that is, it depends on where you run the node.

the __dirname is directory name of the current module.

Try this:

CREATE PROCEDURE MyProc @excludedlist integer_list_tbltype READONLY AS
  SELECT * FROM A WHERE ID NOT IN (@excludedlist)

And then call it like this:

DECLARE @ExcludedList integer_list_tbltype
INSERT @ExcludedList(n) VALUES(3, 4, 22)
exec MyProc @ExcludedList

Generally I just use the command line for svn, it's the fastest and easiest way to do it to be honest, I'd recommend you try it.
Before you dismiss this, you should probably ask yourself if there is really any feature that you need a GUI for, and whether you would prefer to open up a GUI app and download the files, or just type svn co svn://site-goes-here.org/trunk

You can easily add, remove, move, commit, copy or update files with simple commands given with svn help, so for most users it is more than enough.

size_t and int are not interchangeable. For instance on 64-bit Linux size_t is 64-bit in size (i.e. sizeof(void*)) but int is 32-bit.

Also note that size_t is unsigned. If you need signed version then there is ssize_t on some platforms and it would be more relevant to your example.

As a general rule I would suggest using int for most general cases and only use size_t/ssize_t when there is a specific need for it (with mmap() for example).

append returns None, so at the second iteration you are calling method append of NoneType. Just remove the assignment:

for i in range(0, n):
    list1.append([i])

You can try with jQuery also

$('textarea').css("resize", "none");

Does git reset --hard work for anyone? I am not saying this is a good solution, it just seemed to work first time I tried.

This query will give both field value and length:

db.usercollection.aggregate([
{
    $project: {
        "name": 1,
        "length": { $strLenCP: "$name" }
    }} ])

I had the same problem as you a while back. I can't remember the details but the following code got things working for me. This code is used within a Spring Webflow flow, hence the RequestContext and ExternalContext classes. But the part that is most relevant to you is the doAutoLogin method.

public String registerUser(UserRegistrationFormBean userRegistrationFormBean,
                           RequestContext requestContext,
                           ExternalContext externalContext) {

    try {
        Locale userLocale = requestContext.getExternalContext().getLocale();
        this.userService.createNewUser(userRegistrationFormBean, userLocale, Constants.SYSTEM_USER_ID);
        String emailAddress = userRegistrationFormBean.getChooseEmailAddressFormBean().getEmailAddress();
        String password = userRegistrationFormBean.getChoosePasswordFormBean().getPassword();
        doAutoLogin(emailAddress, password, (HttpServletRequest) externalContext.getNativeRequest());
        return "success";

    } catch (EmailAddressNotUniqueException e) {
        MessageResolver messageResolvable 
                = new MessageBuilder().error()
                                      .source(UserRegistrationFormBean.PROPERTYNAME_EMAIL_ADDRESS)
                                      .code("userRegistration.emailAddress.not.unique")
                                      .build();
        requestContext.getMessageContext().addMessage(messageResolvable);
        return "error";
    }

}


private void doAutoLogin(String username, String password, HttpServletRequest request) {

    try {
        // Must be called from request filtered by Spring Security, otherwise SecurityContextHolder is not updated
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);
        token.setDetails(new WebAuthenticationDetails(request));
        Authentication authentication = this.authenticationProvider.authenticate(token);
        logger.debug("Logging in with [{}]", authentication.getPrincipal());
        SecurityContextHolder.getContext().setAuthentication(authentication);
    } catch (Exception e) {
        SecurityContextHolder.getContext().setAuthentication(null);
        logger.error("Failure in autoLogin", e);
    }

}

There appear to be two problems.

1. You're using the ^ outside a [] which matches the start of the line
2. You're not using a * or + which means you will only match a single character.

I think you want the following regex @"([^a-zA-Z0-9\s])+"

Surprisingly, none of answers talk about how it is achieved by hibernate behind the screens.

Lazy loading is a design pattern that is effectively used in hibernate for performance reasons which involves following techniques.

1. Byte code instrumentation:

Enhances the base class definition with hibernate hooks to intercept all the calls to that entity object.

Done either at compile time or run[load] time

1.1 Compile time

• Post compile time operation

• Mostly by maven/ant plugins

1.2 Run time

• If no compile time instrumentation is done, this is created at run time Using libraries like javassist

2. Proxies

The entity object that Hibernate returns are proxy of the real type.

See also: Javassist. What is the main idea and where real use?

An alternative solution, in case you are needing to do this on an ajax file upload:

var data = new FormData( $('#form')[0] ).append( 'name' , value );

OR even simpler.

$('form').on('submit',function(e){

    e.preventDefault();
    var data = new FormData( this ).append('name', value );

    // ... your ajax code here ...

    return false;

});

It's worth noting that the QuerySet.values_list() method doesn't actually return a list, but an object of type django.db.models.query.ValuesListQuerySet, in order to maintain Django's goal of lazy evaluation, i.e. the DB query required to generate the 'list' isn't actually performed until the object is evaluated.

Somewhat irritatingly, though, this object has a custom __repr__ method which makes it look like a list when printed out, so it's not always obvious that the object isn't really a list.

The exception in the question is caused by the fact that custom objects cannot be serialized in JSON, so you'll have to convert it to a list first, with...

my_list = list(self.get_queryset().values_list('code', flat=True))

...then you can convert it to JSON with...

json_data = json.dumps(my_list)

You'll also have to place the resulting JSON data in an HttpResponse object, which, apparently, should have a Content-Type of application/json, with...

response = HttpResponse(json_data, content_type='application/json')

...which you can then return from your function.

you can update the setting under init.ora in oraclexe\app\oracle\product\11.2.0\server\config\scripts

The solution provided by BBoy works fine. But in my case I had to use

e.Graphics.DrawImage(memoryImage, e.PageBounds);

This will print only the form. When I use MarginBounds it prints the entire screen even if the form is smaller than the monitor screen. PageBounds solved that issue. Thanks to BBoy!

I would use scikit-learn's own training_test_split, and generate it from the index

from sklearn.model_selection import train_test_split


y = df.pop('output')
X = df

X_train,X_test,y_train,y_test = train_test_split(X.index,y,test_size=0.2)
X.iloc[X_train] # return dataframe train

You can use the $$ variable.

For me, adding the following block of code under <dependency management><dependencies> solved the problem.

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.1-b06</version>
</dependency>

GhostDoc!

Right-click on the function, select "Document this" and

private bool FindTheFoo(int numberOfFoos)

becomes

/// <summary>
/// Finds the foo.
/// </summary>
/// <param name="numberOfFoos">The number of foos.</param>
/// <returns></returns>
private bool FindTheFoo(int numberOfFoos)

(yes, it is all autogenerated).

It has support for C#, VB.NET and C/C++. It is per default mapped to Ctrl+Shift+D.

Remember: you should add information beyond the method signature to the documentation. Don't just stop with the autogenerated documentation. The value of a tool like this is that it automatically generates the documentation that can be extracted from the method signature, so any information you add should be new information.

That being said, I personally prefer when methods are totally selfdocumenting, but sometimes you will have coding-standards that mandate outside documentation, and then a tool like this will save you a lot of braindead typing.

List<T> has two methods you can use.

RemoveAt(int index) can be used if you know the index of the item. For example:

resultlist.RemoveAt(1);

Or you can use Remove(T item):

var itemToRemove = resultlist.Single(r => r.Id == 2);
resultList.Remove(itemToRemove);

When you are not sure the item really exists you can use SingleOrDefault. SingleOrDefault will return null if there is no item (Single will throw an exception when it can't find the item). Both will throw when there is a duplicate value (two items with the same id).

var itemToRemove = resultlist.SingleOrDefault(r => r.Id == 2);
if (itemToRemove != null)
    resultList.Remove(itemToRemove);

There could be a mistake in @JARH's answer in the case of a multivariable regression. (I do not have enough reputation to comment.)

In the following line:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-1))) for i in ts_b],

the t-values follows a chi-squared distribution of degree len(newX)-1 instead of following a chi-squared distribution of degree len(newX)-len(newX.columns)-1.

So this should be:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-len(newX.columns)-1))) for i in ts_b]

(See t-values for OLS regression for more details)

    :-) Sunday    |    0  ->  Sun

As you can see above, and as said before, the numbers 0 and 7 are both assigned to Sunday. There are also the English abbreviated days of the week listed, which can also be used in the crontab.

Examples of Number or Abbreviation Use

15 09 * * 5,6,0             command
15 09 * * 5,6,7             command
15 09 * * 5-7               command
15 09 * * Fri,Sat,Sun       command

The four examples do all the same and execute a command every Friday, Saturday, and Sunday at 9.15 o'clock.

In Detail

Having two numbers 0 and 7 for Sunday can be useful for writing weekday ranges starting with 0 or ending with 7. So you can write ranges starting with Sunday or ending with it, like 0-2 or 5-7 for example (ranges must start with the lower number and must end with the higher). The abbreviations cannot be used to define a weekday range.

The class.__stuff naming convention lets the programmer know he isn't meant to access __stuff from outside. The name mangling makes it unlikely anyone will do it by accident.

True, you still can work around this, it's even easier than in other languages (which BTW also let you do this), but no Python programmer would do this if he cares about encapsulation.

removing this line fixed one last place needed for complete removal. I am not sure how that entry was added but it helped

I am surprised nobody used flex which is easier to understand, so I put my version of answer here:

1. To create a circle, make sure width equals height
2. To adapt to font-size of number in the circle, use em rather than px
3. To center the number in the circle, use flex with justify-content: center; align-items: center;
4. if the number grows (>1000 for example), increase the width and height at same time

Here is an example:

.circled-number {
  color: #666;
  border: 2px solid #666;
  border-radius: 50%;
  font-size: 1rem;
  display: flex;
  justify-content: center;
  align-items: center;
  width: 2em; 
  height: 2em;
}

.circled-number--big {
  color: #666;
  border: 2px solid #666;
  border-radius: 50%;
  font-size: 1rem;
  display: flex;

SyntaxError: non-default argument follows default argument

If you were to allow this, the default arguments would be rendered useless because you would never be able to use their default values, since the non-default arguments come after.

In Python 3 however, you may do the following:

def fun1(a="who is you", b="True", *, x, y):
    pass

which makes x and y keyword only so you can do this:

fun1(x=2, y=2)

This works because there is no longer any ambiguity. Note you still can't do fun1(2, 2) (that would set the default arguments).

"Chrome violations" don't represent errors in either Chrome or your own web app. They are instead warnings to help you improve your app. In this case, Long running JavaScript and took 83ms of runtime are alerting you there's probably an opportunity to speed up your script.

("Violation" is not the best terminology; it's used here to imply the script "violates" a pre-defined guideline, but "warning" or similar would be clearer. These messages first appeared in Chrome in early 2017 and should ideally have a "More info" prompt to elaborate on the meaning and give suggested actions to the developer. Hopefully those will be added in the future.)

If for loops are on short supply, here's what I like to use:

$s = substr(str_shuffle(str_repeat("0123456789abcdefghijklmnopqrstuvwxyz", 5)), 0, 5);

For anyone else having issues when using GNU find binary in a Windows command prompt. The semicolon needs to be escaped with ^

find.exe . -name "*.rm" -exec ffmpeg -i {} -sameq {}.mp3 ^;

From your question, I think what you are trying to do is to store something (an object, a string...) to foward it then to another servlet, using RequestDispatcher(). To do this you don't need to set a paramater but an attribute using

void setAttribute(String name, Object o);

and then

Object getAttribute(String name);

here is the answer for IE 8

AND IT WORKS for alpha to work in IE8 you have to use position atribute for that element like

position:relative or other.

They are basically the fullest learned model you can get from the network, before it's been squashed down to apply to only the number of classes we are interested in. Check out how some researchers use them to train a shallow neural net based on what a deep network has learned: https://arxiv.org/pdf/1312.6184.pdf

It's kind of like how when learning a subject in detail, you will learn a great many minor points, but then when teaching a student, you will try to compress it to the simplest case. If the student now tried to teach, it'd be quite difficult, but would be able to describe it just well enough to use the language.

If you're running using uwsgi look at the python auto reload option:

uwsgi --py-autoreload 1

Example uwsgi-dev-example.ini:

[uwsgi]
socket = 127.0.0.1:5000
master = true
virtualenv = /Users/xxxx/.virtualenvs/sites_env
chdir = /Users/xxx/site_root
module = site_module:register_debug_server()
callable = app
uid = myuser
chmod-socket = 660
log-date = true
workers = 1
py-autoreload = 1

site_root/__init__.py

def register_debug_server():
    from werkzeug.debug import DebuggedApplication

    app = Flask(__name__)
    app.debug = True
    app = DebuggedApplication(app, evalex=True)
    return app

Then run:

uwsgi --ini uwsgi-dev-example.ini

Note: This example also enables the debugger.

I went this route to mimic production as close as possible with my nginx setup. Simply running the flask app with it's built in web server behind nginx it would result in a bad gateway error.

Why not just use all Lambda syntax?

database.Stores.Where(s => s.CompanyID == curCompany.ID)
               .Select(s => new SelectListItem
                   {
                       Value = s.Name,
                       Text = s.ID
                   });

WHERE AND SELECT Condition In Array Format Laravel

use DB;

$conditions = array(
    array('email', '=', '[email protected]')

The way I did it can be found in this Stack Overflow question.

It is important to use resetModules before each test and then dynamically import the module inside the test:

describe('environmental variables', () => {
  const OLD_ENV = process.env;

  beforeEach(() => {
    jest.resetModules() // Most important - it clears the cache
    process.env = { ...OLD_ENV }; // Make a copy
  });

  afterAll(() => {
    process.env = OLD_ENV; // Restore old environment
  });

  test('will receive process.env variables', () => {
    // Set the variables
    process.env.NODE_ENV = 'dev';
    process.env.PROXY_PREFIX = '/new-prefix/';
    process.env.API_URL = 'https://new-api.com/';
    process.env.APP_PORT = '7080';
    process.env.USE_PROXY = 'false';

    const testedModule = require('../../config/env').default

    // ... actual testing
  });
});

If you look for a way to load environment values before running the Jest look for the answer below. You should use setupFiles for that.

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

Use option bty = "n" in legend to remove the box around the legend. For example:

legend(1, 5,
       "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",
       bty = "n")

this in JavaScript always refers to the 'owner' of the function that is being executed.

If no explicit owner is defined, then the top most owner, the window object, is referenced.

So if I did

function someKindOfFunction() {
   this.style = 'foo';
}

element.onclick = someKindOfFunction;

this would refer to the element object. But be careful, a lot of people make this mistake.

<element onclick="someKindOfFunction()">

In the latter case, you merely reference the function, not hand it over to the element. Therefore, this will refer to the window object.

I wanted the simplest case, finally this is a result:

echo -n 'Tell me the length of this sentence.' | wc -m;
36

Including numbers but not whitespace:

"Stack Me 123 Heppa1 oeu".replaceAll("\\W","").toCharArray();

=> S, t, a, c, k, M, e, 1, 2, 3, H, e, p, p, a, 1, o, e, u

Without numbers and whitespace:

"Stack Me 123 Heppa1 oeu".replaceAll("[^a-z^A-Z]","").toCharArray()

=> S, t, a, c, k, M, e, H, e, p, p, a, o, e, u

If you do not use the sender argument, why not refactor the button handler implementation to separate function, and call it from wherever you want (from the button handler and from the other place).

Anyway, it is a better and cleaner design - a code that needs to be called on button handler AND from some other places deserves to be refactored to own function. Plus it will help you separate UI handling from application logic code. You will also have a nice name to the function, not just onDateSelectedButtonClick().

it is for empty table:

ALTER TABLE `table_name` AUTO_INCREMENT = 1;

if you have data but you want to tidy up it, i recommend use this :

ALTER TABLE `table_name` DROP `auto_colmn`;
ALTER TABLE `table_name` ADD  `auto_colmn` INT( {many you want} ) NOT NULL AUTO_INCREMENT FIRST ,ADD PRIMARY KEY (`auto_colmn`);

Use this

Event assigning always after Document Object Model loaded

You can do it like this by iterating through the array in a loop, accumulating the new HTML into it's own array and then joining the HTML all together and inserting it into the DOM at the end:

var array = [...];
var newHTML = [];
for (var i = 0; i < array.length; i++) {
    newHTML.push('<span>' + array[i] + '</span>');
}
$(".element").html(newHTML.join(""));

Some people prefer to use jQuery's .each() method instead of the for loop which would work like this:

var array = [...];
var newHTML = [];
$.each(array, function(index, value) {
    newHTML.push('<span>' + value + '</span>');
});
$(".element").html(newHTML.join(""));

Or because the output of the array iteration is itself an array with one item derived from each item in the original array, jQuery's .map can be used like this:

var array = [...];
var newHTML = $.map(array, function(value) {
    return('<span>' + value + '</span>');
});
$(".element").html(newHTML.join(""));

Which you should use is a personal choice depending upon your preferred coding style, sensitivity to performance and familiarity with .map(). My guess is that the for loop would be the fastest since it has fewer function calls, but if performance was the main criteria, then you would have to benchmark the options to actually measure.

FYI, in all three of these options, the HTML is accumulated into an array, then joined together at the end and the inserted into the DOM all at once. This is because DOM operations are usually the slowest part of an operation like this so it's best to minimize the number of separate DOM operations. The results are accumulated into an array because adding items to an array and then joining them at the end is usually faster than adding strings as you go.

And, if you can live with IE9 or above (or install an ES5 polyfill for .map()), you can use the array version of .map like this:

var array = [...];
$(".element").html(array.map(function(value) {
    return('<span>' + value + '</span>');
}).join(""));

Note: this version also gets rid of the newHTML intermediate variable in the interest of compactness.

I didn't find any of the mentioned options to be correct or work for me when I came to this page. They did give me ideas to test things out and I found that this worked for me.

dontGoToLink(e) {
  e.preventDefault();
 }

render() {
  return (<a href="test.com" onClick={this.dontGoToLink} />});
}

Use StringUtils.isEmpty instead, it will also check for null.

Examples are:

 StringUtils.isEmpty(null)      = true
 StringUtils.isEmpty("")        = true
 StringUtils.isEmpty(" ")       = false
 StringUtils.isEmpty("bob")     = false
 StringUtils.isEmpty("  bob  ") = false

See more on official Documentation on String Utils.

My understanding is that this is actually very simple:

• Javascript is always pass by value, but when a variable refers to an object (including arrays), the "value" is a reference to the object.
• Changing the value of a variable never changes the underlying primitive or object, it just points the variable to a new primitive or object.
• However, changing a property of an object referenced by a variable does change the underlying object.

So, to work through some of your examples:

function f(a,b,c) {
    // Argument a is re-assigned to a new value.
    // The object or primitive referenced by the original a is unchanged.
    a = 3;
    // Calling b.push changes its properties - it adds
    // a new property b[b.length] with the value "foo".
    // So the object referenced by b has been changed.
    b.push("foo");
    // The "first" property of argument c has been changed.
    // So the object referenced by c has been changed (unless c is a primitive)
    c.first = false;
}

var x = 4;
var y = ["eeny", "miny", "mo"];
var z = {first: true};
f(x,y,z);
console.log(x, y, z.first); // 4, ["eeny", "miny", "mo", "foo"], false

Example 2:

var a = ["1", "2", {foo:"bar"}];
var b = a[1]; // b is now "2";
var c = a[2]; // c now references {foo:"bar"}
a[1] = "4";   // a is now ["1", "4", {foo:"bar"}]; b still has the value
              // it had at the time of assignment
a[2] = "5";   // a is now ["1", "4", "5"]; c still has the value
              // it had at the time of assignment, i.e. a reference to
              // the object {foo:"bar"}
console.log(b, c.foo); // "2" "bar"

char originalString[] = "THESTRINGHASNOSPACES";

    char aux[5];
    int j=0;
    for(int i=0;i<strlen(originalString);i++){
        aux[j] = originalString[i];
        if(j==3){
            aux[j+1]='\0'; 
            printf("%s\n",aux);
            j=0;
        }else{
            j++;
        }
    }

Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate
{
    //Update UI here
}));

Syntax

[BrowsableAttribute(false)]
public object Invoke(
  DispatcherPriority priority,
  Delegate method
)

Parameters

priority

Type: System.Windows.Threading.DispatcherPriority

The priority, relative to the other pending operations in the Dispatcher event queue, the specified method is invoked.

method

Type: System.Delegate

A delegate to a method that takes no arguments, which is pushed onto the Dispatcher event queue.

Return Value

Type: System.Object

The return value from the delegate being invoked or null if the delegate has no return value.

If you have this in your CSS file:

.myApp
{
    border-bottom-color:#FF0000;
}

and a div for instance of:

<div id="myDiv">test text</div>

you can use:

$("#myDiv").addClass('myApp');// to add the style

$("#myDiv").removeClass('myApp');// to remove the style

or you can just use

$("#myDiv").css( 'border-bottom-color','#FF0000');

I prefer the first example, keeping all the CSS related items in the CSS files.

Do you want the files to save as UTF-8 because you are using special characters that would be lost in ASCII encoding? If that's the case, then there is a VS2008 global setting in Tools > Options > Environment > Documents, named Save documents as Unicode when data cannot be saved in codepage. When this is enabled, VS2008 will save as Unicode if certain characters cannot be represented in the otherwise-default codepage.

Also, which files are not being saved as UTF-8? All of my .cs, .csproj, .sln, .config, .as*x, etc, all save as UTF-8 (with signature, the byte order marks), by default.

How about this:

SELECT SUBSTRING_INDEX(
      MIN(CONCAT(OrderColumn, '|', IFNULL(TargetColumn, ''))
    ), '|', -1) as TargetColumn
FROM table
GROUP BY GroupColumn

Firstly, Add this android:debuggable="false" in the application tag of the AndroidManifest.xml.

You don't need to harcode android:debuggable="false" in your application tag. Infact for me studio complaints -

Avoid hardcoding the debug mode; leaving it out allows debug and release builds to automatically assign one less... (Ctrl+F1)

It's best to leave out the android:debuggable attribute from the manifest. If you do, then the tools will automatically insert android:debuggable=true when building an APK to debug on an emulator or device. And when you perform a release build, such as Exporting APK, it will automatically set it to false. If on the other hand you specify a specific value in the manifest file, then the tools will always use it. This can lead to accidentally publishing your app with debug information.

The accepted answer looks somewhat old. For me it asks me to select whether I want debug build or release build.

Go to Build->Generate Signed APK. Select your keystore, provide keystore password etc.

Now you should see a prompt to select release build or debug build.

For production always select release build!

And you are done. Signed APK exported.

PS : Don't forget to increment your versionCode in manifest file before uploading to playstore :)

moment("01:15:00 PM", "h:mm:ss A").format("HH:mm:ss")
**o/p: 13:15:00 **

it will give convert 24 hrs format to 12 hrs format.

You will need to create a public/private key as the Jenkins user on your Jenkins server, then copy the public key to the user you want to do the deployment with on your target server.

Step 1, generate public and private key on build server as user jenkins

build1:~ jenkins$ whoami
jenkins
build1:~ jenkins$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa): 
Created directory '/var/lib/jenkins/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /var/lib/jenkins/.ssh/id_rsa.
Your public key has been saved in /var/lib/jenkins/.ssh/id_rsa.pub.
The key fingerprint is:
[...] 
The key's randomart image is:
[...]
build1:~ jenkins$ ls -l .ssh
total 2
-rw-------  1 jenkins  jenkins  1679 Feb 28 11:55 id_rsa
-rw-r--r--  1 jenkins  jenkins   411 Feb 28 11:55 id_rsa.pub 
build1:~ jenkins$ cat .ssh/id_rsa.pub
ssh-rsa AAAlskdjfalskdfjaslkdjf... [email protected]

Step 2, paste the pub file contents onto the target server.

target:~ bob$ cd .ssh
target:~ bob$ vi authorized_keys (paste in the stuff which was output above.)

Make sure your .ssh dir has permissoins 700 and your authorized_keys file has permissions 644

Step 3, configure Jenkins

1. In the jenkins web control panel, nagivate to "Manage Jenkins" -> "Configure System" -> "Publish over SSH"
2. Either enter the path of the file e.g. "var/lib/jenkins/.ssh/id_rsa", or paste in the same content as on the target server.
3. Enter your passphrase, server and user details, and you are good to go!

tl;dr

LocalDate.of( 2018 , Month.JANUARY , 23 )
         .format( DateTimeFormatter.ofPattern( “uuuu-MM-EEE” , Locale.US )  )

java.time

The modern approach uses the java.time classes.

LocalDate ld = LocalDate.of( 2018 , Month.JANUARY , 23 ) ;

Note how we specify a Locale such as Locale.CANADA_FRENCH to determine the human language used to translate the name of the day.

DateTimeFormatter f = DateTimeFormatter.ofPattern( “uuuu-MM-EEE” , Locale.US ) ;
String output = ld.format( f ) ;

ISO 8601

By the way, you may be interested in the standard ISO 8601 week numbering scheme: yyyy-Www-d.

2018-W01-2

Week # 1 has the first Thursday of the calendar-year. Week starts on a Monday. A year has either 52 or 53 weeks. The last/first few days of a calendar-year may land in the next/previous week-based-year.

The single digit on the end is day-of-week, 1-7 for Monday-Sunday.

Add the ThreeTen-Extra library class to your project for the YearWeek class.

About java.time

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

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

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

Where to obtain the java.time classes?

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

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

This has changed in the newer versions of Ember.

For arrays:

{{#each array}}
    {{_view.contentIndex}}: {{this}}
{{/each}}

It looks like the #each block no longer works on objects. My suggestion is to roll your own helper function for it.

Thanks for this tip.

Let's say you have your global scripts file and you don't want to define that URL repeatedly in other files. That's the point where BASE_URL kicks in.

In your global_script.js file, do this

<script>
 var BASE_URL = "http://localhost:8000";
</script>

Then you can use that variable anywhere else to call your URL. For example...

<script>
   fetch(`{{BASE_URL}}/task-create/`,{
         ..............
            
        }).then((response) => {
            .............
   })
</script>

  hues = seq(15, 375, length = n + 1)
  hcl(h = hues, l = 65, c = 100)[1:n]
}

For example:

n = 4
cols = gg_color_hue(n)

dev.new(width = 4, height = 4)
plot(1:n, pch = 16, cex = 2, col = cols)

set -x

Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.

[source]

Example

set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30

set +x
echo `expr 10 + 20 `
30

Above example illustrates the usage of set -x. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

• First step expr has been evaluated.
• Second step echo has been evaluated.

when it comes to your shell script,

[ "$DEBUG" == 'true' ] && set -x

Your script might have been printing some additional lines of information when the execution mode selected as DEBUG. Traditionally people used to enable debug mode when a script called with optional argument such as -d

You need to add a listener to the request because node.js works asynchronous like that:

request.on('response', function (response) {
  response.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
 });
});

There are several helpful bits of code for this.

Place your cursor in a merged cell and ask these questions in the Immidiate Window:

Is the activecell a merged cell?

? Activecell.Mergecells
 True

How many cells are merged?

? Activecell.MergeArea.Cells.Count
 2

How many columns are merged?

? Activecell.MergeArea.Columns.Count
 2

How many rows are merged?

? Activecell.MergeArea.Rows.Count
  1

What's the merged range address?

? activecell.MergeArea.Address
  $F$2:$F$3

You want to have a look at FileField and FieldFile in the Django docs, and especially FieldFile.save().

Basically, a field declared as a FileField, when accessed, gives you an instance of class FieldFile, which gives you several methods to interact with the underlying file. So, what you need to do is:

self.license_file.save(new_name, new_contents)

where new_name is the filename you wish assigned and new_contents is the content of the file. Note that new_contents must be an instance of either django.core.files.File or django.core.files.base.ContentFile (see given links to manual for the details).

The two choices boil down to:

from django.core.files.base import ContentFile, File

# Using File
with open('/path/to/file') as f:
    self.license_file.save(new_name, File(f))

# Using ContentFile
self.license_file.save(new_name, ContentFile('A string with the file content'))

if ngModule is not working in input means try...remove double quotes around ngModule

like

<input #form="ngModel" [(ngModel)]......></input>

instead of above

<input #form=ngModel [(ngModel)]......></input> try this

I would make a minor change to Frederik's solution. I would use the sp_spaceused system stored procedure which will also include data and index sizes.

declare c_tables cursor fast_forward for 
select table_name from information_schema.tables 

open c_tables 
declare @tablename varchar(255) 
declare @stmt nvarchar(2000) 
declare @rowcount int 
fetch next from c_tables into @tablename 

while @@fetch_status = 0 
begin 

    select @stmt = 'sp_spaceused ' + @tablename 

    exec sp_executesql @stmt

    fetch next from c_tables into @tablename 

end 

close c_tables 
deallocate c_tables 

I found the answer here: Is it possible to pass query parameters via Django's {% url %} template tag?

Simply add them to the end:

<a href="{% url myview %}?office=foobar">
For Django 1.5+

<a href="{% url 'myview' %}?office=foobar">

[there is nothing else to improve but I'm getting a stupid error when I fix the code ticks]

There is a way to do this, without resorting to the system call, you need to incorporate a wrapper something like this:

#include <sys/sendfile.h>
#include <fcntl.h>
#include <unistd.h>

/* 
** http://www.unixguide.net/unix/programming/2.5.shtml 
** About locking mechanism...
*/

int copy_file(const char *source, const char *dest){
   int fdSource = open(source, O_RDWR);

   /* Caf's comment about race condition... */
   if (fdSource > 0){
     if (lockf(fdSource, F_LOCK, 0) == -1) return 0; /* FAILURE */
   }else return 0; /* FAILURE */

   /* Now the fdSource is locked */

   int fdDest = open(dest, O_CREAT);
   off_t lCount;
   struct stat sourceStat;
   if (fdSource > 0 && fdDest > 0){
      if (!stat(source, &sourceStat)){
          int len = sendfile(fdDest, fdSource, &lCount, sourceStat.st_size);
          if (len > 0 && len == sourceStat.st_size){
               close(fdDest);
               close(fdSource);

               /* Sanity Check for Lock, if this is locked -1 is returned! */
               if (lockf(fdSource, F_TEST, 0) == 0){
                   if (lockf(fdSource, F_ULOCK, 0) == -1){
                      /* WHOOPS! WTF! FAILURE TO UNLOCK! */
                   }else{
                      return 1; /* Success */
                   }
               }else{
                   /* WHOOPS! WTF! TEST LOCK IS -1 WTF! */
                   return 0; /* FAILURE */
               }
          }
      }
   }
   return 0; /* Failure */
}

The above sample (error checking is omitted!) employs open, close and sendfile.

Edit: As caf has pointed out a race condition can occur between the open and stat so I thought I'd make this a bit more robust...Keep in mind that the locking mechanism varies from platform to platform...under Linux, this locking mechanism with lockf would suffice. If you want to make this portable, use the #ifdef macros to distinguish between different platforms/compilers...Thanks caf for spotting this...There is a link to a site that yielded "universal locking routines" here.

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Further explanation: How does Python compare string and int?

If you are using the GNU C library or another POSIX-compliant library, you can use getline() and pass stdin to it for the file stream.

$setValidity needs to be called on the ngModelController. Inside the controller, I think that means $scope.myForm.file.$setValidity().

See also section "Custom Validation" on the Forms page, if you haven't already.

Also, for the first argument to $setValidity, use just 'filetype' and 'size'.

const destroy = container => {
  document.getElementById(container).innerHTML = '';
};

Faster previous

const destroyFast = container => {
  const el = document.getElementById(container);
  while (el.firstChild) el.removeChild(el.firstChild);
};

For me my mac OS is Mojave. and I'm facing the same issue for three days and in the end, I just write the correct path in the .bash_profile file which is like this:

    export PATH=/Users/[YOURNAME]/development/flutter/bin:$PATH

• note1: if u don't have .bash_profile create one and write the line above
• note2: zip your downloaded flutter SDK in [home]/development if you copy and paste this path

I had this same problem installing SQL Server 2014. Turns out it was due to a Windows Phone toolkit that I had installed back in 2010. If you run into this, make sure you uninstall any Windows phone stuff that isn't current.

I figured it out by looking at the log, which can be found by clicking "Detailed Report," which opens an HTML file. The file path is conveniently displayed within the HTML page. Open the directory that the file is in and look for "Detail.txt." Then search for the word "fail."

In my case there was a line showing WP_[something] as "Installed." I searched for the WP_ item and came across some blog posts about trouble uninstalling Windows Phone toolkits.

When I attempted to uninstall the windows phone I ran into more trouble. The uninstaller wanted to install three packages instead of uninstalling the toolkit. Eventually found this blog post: http://blogs.msdn.com/b/astebner/archive/2010/07/12/10037442.aspx linking to this XNA cleanup tool: http://blogs.msdn.com/b/astebner/archive/2009/04/10/9544320.aspx.

I ran the cleanup tool and finally SQL Server installer passed the check and allowed me to install. Hope this helps someone.

As said before modulo isn't sufficient because it skews the distribution. Heres my code which masks off bits and uses them to ensure the distribution isn't skewed.

static uint32_t randomInRange(uint32_t a,uint32_t b) {
    uint32_t v;
    uint32_t range;
    uint32_t upper;
    uint32_t lower;
    uint32_t mask;

    if(a == b) {
        return a;
    }

    if(a > b) {
        upper = a;
        lower = b;
    } else {
        upper = b;
        lower = a; 
    }

    range = upper - lower;

    mask = 0;
    //XXX calculate range with log and mask? nah, too lazy :).
    while(1) {
        if(mask >= range) {
            break;
        }
        mask = (mask << 1) | 1;
    }


    while(1) {
        v = rand() & mask;
        if(v <= range) {
            return lower + v;
        }
    }

}

The following simple code lets you look at the distribution:

int main() {

    unsigned long long int i;


    unsigned int n = 10;
    unsigned int numbers[n];


    for (i = 0; i < n; i++) {
        numbers[i] = 0;
    }

    for (i = 0 ; i < 10000000 ; i++){
        uint32_t rand = random_in_range(0,n - 1);
        if(rand >= n){
            printf("bug: rand out of range %u\n",(unsigned int)rand);
            return 1;
        }
        numbers[rand] += 1;
    }

    for(i = 0; i < n; i++) {
        printf("%u: %u\n",i,numbers[i]);
    }

}

For the Javadoc tag @see, you don't need to use @link; Javadoc will create a link for you. Try

@see com.my.package.Class#method()

Here's more info about @see.

Right after @mail($email_to, $email_subject, $email_message, $headers);

header('Location: nextpage.php');

Note that you will never see 'Thanks for subscribing to our mailing list'

That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!

You mean Selenium WebDriver? Huh....

Prerequisite: Install Python based on your OS

Install with following command

pip install -U selenium

And use this module in your code

from selenium import webdriver

You can also use many of the following as required

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException

Here is an updated answer

I would recommend you to run script without IDE... Here is my approach

1. USE IDE to find xpath of object / element
2. And use find_element_by_xpath().click()

An example below shows login page automation

#ScriptName : Login.py
#---------------------
from selenium import webdriver

#Following are optional required
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException

baseurl = "http://www.mywebsite.com/login.php"
username = "admin"
password = "admin"

xpaths = { 'usernameTxtBox' : "//input[@name='username']",
           'passwordTxtBox' : "//input[@name='password']",
           'submitButton' :   "//input[@name='login']"
         }

mydriver = webdriver.Firefox()
mydriver.get(baseurl)
mydriver.maximize_window()

#Clear Username TextBox if already allowed "Remember Me" 
mydriver.find_element_by_xpath(xpaths['usernameTxtBox']).clear()

#Write Username in Username TextBox
mydriver.find_element_by_xpath(xpaths['usernameTxtBox']).send_keys(username)

#Clear Password TextBox if already allowed "Remember Me" 
mydriver.find_element_by_xpath(xpaths['passwordTxtBox']).clear()

#Write Password in password TextBox
mydriver.find_element_by_xpath(xpaths['passwordTxtBox']).send_keys(password)

#Click Login button
mydriver.find_element_by_xpath(xpaths['submitButton']).click()

There is an another way that you can find xpath of any object -

1. Install Firebug and Firepath addons in firefox
2. Open URL in Firefox
3. Press F12 to open Firepath developer instance
4. Select Firepath in below browser pane and chose select by "xpath"
5. Move cursor of the mouse to element on webpage
6. in the xpath textbox you will get xpath of an object/element.
7. Copy Paste xpath to the script.

Run script -

python Login.py

You can also use a CSS selector instead of xpath. CSS selectors are slightly faster than xpath in most cases, and are usually preferred over xpath (if there isn't an ID attribute on the elements you're interacting with).

Firepath can also capture the object's locator as a CSS selector if you move your cursor to the object. You'll have to update your code to use the equivalent find by CSS selector method instead -

find_element_by_css_selector(css_selector) 

1 byte may hold 1 character. For Example: Refer Ascii values for each character & convert into binary. This is how it works.

value 255 is stored as (11111111) base 2. Visit this link for knowing more about binary conversion. http://acc6.its.brooklyn.cuny.edu/~gurwitz/core5/nav2tool.html

Size of Tiny Int = 1 Byte ( -128 to 127)

Int = 4 Bytes (-2147483648 to 2147483647)

Try library(getopt) ... if you want things to be nicer. For example:

spec <- matrix(c(
        'in'     , 'i', 1, "character", "file from fastq-stats -x (required)",
        'gc'     , 'g', 1, "character", "input gc content file (optional)",
        'out'    , 'o', 1, "character", "output filename (optional)",
        'help'   , 'h', 0, "logical",   "this help"
),ncol=5,byrow=T)

opt = getopt(spec);

if (!is.null(opt$help) || is.null(opt$in)) {
    cat(paste(getopt(spec, usage=T),"\n"));
    q();
}

They are the opposites of each other.

JSON.stringify()

JSON.stringify() serializes a JS object or value into a JSON string.

JSON.stringify({});                  // '{}'
JSON.stringify(true);                // 'true'
JSON.stringify('foo');               // '"foo"'
JSON.stringify([1, 'false', false]); // '[1,"false",false]'
JSON.stringify({ x: 5 });            // '{"x":5}'

JSON.stringify(new Date(2006, 0, 2, 15, 4, 5)) 
// '"2006-01-02T15:04:05.000Z"'

JSON.stringify({ x: 5, y: 6 });
// '{"x":5,"y":6}' or '{"y":6,"x":5}'
JSON.stringify([new Number(1), new String('false'), new Boolean(false)]);
// '[1,"false",false]'

JSON.parse()

The JSON.parse() method parses a string as JSON, optionally transforming the value produced.

JSON.parse('{}');              // {}
JSON.parse('true');            // true
JSON.parse('"foo"');           // "foo"
JSON.parse('[1, 5, "false"]'); // [1, 5, "false"]
JSON.parse('null');            // null

delete operator is used to remove an object property.

delete operator does not returns the new object, only returns a boolean: true or false.

In the other hand, after interpreter executes var updatedjsonobj = delete myjsonobj['otherIndustry']; , updatedjsonobj variable will store a boolean value.

How to remove Json object specific key and its value ?

You just need to know the property name in order to delete it from the object's properties.

delete myjsonobj['otherIndustry'];

let myjsonobj = {
  "employeeid": "160915848",
  "firstName": "tet",
  "lastName": "test",
  "email": "[email protected]",
  "country": "Brasil",
  "currentIndustry": "aaaaaaaaaaaaa",
  "otherIndustry": "aaaaaaaaaaaaa",
  "currentOrganization": "test",
  "salary": "1234567"
}
delete myjsonobj['otherIndustry'];
console.log(myjsonobj);

If you want to remove a key when you know the value you can use Object.keys function which returns an array of a given object's own enumerable properties.

let value="test";
let myjsonobj = {
      "employeeid": "160915848",
      "firstName": "tet",
      "lastName": "test",
      "email": "[email protected]",
      "country": "Brasil",
      "currentIndustry": "aaaaaaaaaaaaa",
      "otherIndustry": "aaaaaaaaaaaaa",
      "currentOrganization": "test",
      "salary": "1234567"
}
Object.keys(myjsonobj).forEach(function(key){
  if (myjsonobj[key] === value) {
    delete myjsonobj[key];
  }
});
console.log(myjsonobj);

You should have something like this:

$('body').click(function() {
   // do something here
});

The callback function will be called when the user clicks somewhere on the web page. You can trigger the callback programmatically with:

$('body').trigger('click');

In my case I changed the datetime field in the SQL database to not allow null. SqlDataReader then allowed me to cast the value directly to a DateTime.

I had the same issue and basically resolved it by pointing to a specific port number that my MySQL server was running on. Below is the command. Please edit the code to fit your case i.e your port number,your mysql server username,your password.

    mysql -u root -pYourMysqlRootPassword -P3307 

For a variable:

foo.h:

class foo
{
private:
    static int i;
};

foo.cpp:

int foo::i = 0;

This is because there can only be one instance of foo::i in your program. It's sort of the equivalent of extern int i in a header file and int i in a source file.

For a constant you can put the value straight in the class declaration:

class foo
{
private:
    static int i;
    const static int a = 42;
};

you can use QString::fromAscii()

QByteArray data = entity->getData();
QString s_data = QString::fromAscii(data.data());

with data() returning a char*

for QT5, you should use fromCString() instead, as fromAscii() is deprecated, see https://bugreports.qt-project.org/browse/QTBUG-21872 https://bugreports.qt.io/browse/QTBUG-21872

I stumbled on this question as I had the same error. Mine was due to a slightly different problem and since I resolved it on my own I thought it useful to share here. Original code with issue:

$comment = "$_POST['comment']";

Because of the enclosing double-quotes, the index is not dereferenced properly leading to the assignment error. In my case I chose to fix it like this:

$comment = "$_POST[comment]";

but dropping either pair of quotes works; it's a matter of style I suppose :)

The root of the problem is that you are unknowingly using the Frame class from the ttk package rather than from the tkinter package. The one from ttk does not support the background option.

This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.

I recommend doing imports like this:

import tkinter as tk
import ttk

Then you prefix the widgets with either tk or ttk :

f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)

It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.

"Using HTML5/Canvas/JavaScript to take screenshots" answers your problem.

You can use JavaScript/Canvas to do the job but it is still experimental.

You can write own groupby function:

           def groupby(data):
                kv = {}
                for k,v in data:
                    if k not in kv:
                         kv[k]=[v]
                    else:
                        kv[k].append(v)
           return kv

     Run on ipython:
       In [10]: data = [('a', 1), ('b',2),('a',2)]

        In [11]: groupby(data)
        Out[11]: {'a': [1, 2], 'b': [2]}

Looking in the headers sent...
res.send uses content-type:text/html
res.json uses content-type:application/json

edit: send actually changes what is sent based on what it's given, so strings are sent as text/html, but it you pass it an object it emits application/json.

I know this is a bit old, but here is a much easier way...

1. Run your query with default settings (puts results in grid format, if your's is not in grid format, see below)

2. Right click on grid results and click "Save Results As" and save it.

If your results are not in grid format, right click where you write the query, hover "Results To" and click "Results To Grid"

Be aware you do NOT capture the column headers!

Good Luck!

In Intellij13, you can use Editor configuration like below:

I'm Using Windows 8.1 and I use this command

c:\wamp\bin\mysql\mysql5.6.12\bin\mysql.exe

instead of

 c:\wamp\bin\mysql\mysql5.6.12\bin\mysqld

and it works fine..

Did you try showing your window using the ShowDialog method?

Don't forget to set the Owner property on the dialog window to the main window. This will avoid weird behavior when Alt+Tabbing, etc.

The @CustID means it's a parameter that you will supply a value for later in your code. This is the best way of protecting against SQL injection. Create your query using parameters, rather than concatenating strings and variables. The database engine puts the parameter value into where the placeholder is, and there is zero chance for SQL injection.

Firstly make sure that you have installed python 2.7 or higher

Open Command Prompt as administrator and change directory to python and then change directory to Scripts by typing cd Scripts then type pip.exe and now you can install modules Step by Step:

• Open Cmd

• type in "cd \" and then enter

• type in "cd python2.7" and then enter

Note that my python version is 2.7 so my directory is that so use your python folder here...

• type in "cd Scripts" and enter

• Now enter this "pip.exe"

• Now it prompts you to install modules

I'd make both the input and label elements display: block , and then split the name label & input, and the email label & input into div's and float them next to each other.

input, label {_x000D_
    display:block;_x000D_
}

<form name="message" method="post">_x000D_
    <section>_x000D_
_x000D_
  <div style="float:left;margin-right:20px;">_x000D_
    <label for="name">Name</label>_x000D_
    <input id="name" type="text" value="" name="name">_x000D_
  </div>_x000D_
_x000D_
  <div style="float:left;">_x000D_
    <label for="email">Email</label>_x000D_
    <input id="email" type="text" value="" name="email">_x000D_
  </div>_x000D_
_x000D_
  <br style="clear:both;" />_x000D_
_x000D_
    </section>_x000D_
_x000D_
    <section>_x000D_
_x000D_
    <label for="subject">Subject</label>_x000D_
    <input id="subject" type="text" value="" name="subject">_x000D_
    <label for="message">Message</label>_x000D_
    <input id="message" type="text" value="" name="message">_x000D_
_x000D_
    </section>_x000D_
</form>

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array( 'prev_text' >' Previous','post_type' => 'page', 'posts_per_page' => 5, 'paged' => $paged );
$wp_query = new WP_Query($args);
while ( have_posts() ) : the_post();
//get all pages 
the_ID();
the_title();

//if you want specific page of content then write
if(get_the_ID=='11')//make sure to use get_the_ID instead the_ID
{
echo get_the_ID();
the_title();
the_content();
}

endwhile;

//if you want specific page of content then write in loop

  if(get_the_ID=='11')//make sure to use get_the_ID instead the_ID
    {
    echo get_the_ID();
    the_title();
    the_content();
    }

You can do this by using properties of textfield from Attribute inspector

Tap on Your Textfield from storyboard and go to Attribute inspector , and just check the checkbox of "Secure Text Entry" SS is added for graphical overview to achieve same

The href is probably generated in a javascript function. For example with jQuery:

$(function() {
    $('a.view').attr('href', 'http://www.google.com');
});

var img = new Image();

img.onload = function(){
  var height = img.height;
  var width = img.width;

  // code here to use the dimensions
}

img.src = url;

This works for me:

git fetch
git rebase --autostash FETCH_HEAD

localStorage.clear();

or

window.localStorage.clear();

to clear particular item

window.localStorage.removeItem("item_name");

To remove particular value by id :

var item_detail = JSON.parse(localStorage.getItem("key_name")) || [];           
            $.each(item_detail, function(index, obj){
                if (key_id == data('key')) {
                    item_detail.splice(index,1);
                    localStorage["key_name"] = JSON.stringify(item_detail);
                    return false;
                }
            });

Fortes is right, thank you.

When you have a shared hosting it is usual to obtain an 500 server error.

I have a website with Joomla and I added to the index.php:

ini_set('display_errors','off');

The error line showed in my website disappeared.

I don't know exactly what you are doing, but float("inf") gives you a float Infinity, which is greater than any other number.

Dialog pop up fill default black background color or theme color so you need to set TRANSPARENT background into Dialog. Try below code:-

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.setContentView(R.layout.splash);
dialog.show();

Update your remote if you still haven't done so:

$ git remote update
$ git branch -r

For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.

The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)

Using this regex:

^(?!.*function).*(\&\$)

it is possible to search project-wide for the occurrence of &$ only in lines that are not a function definition.

This still turns up a lot of false positives, but it does make the job easier.

VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.

First you need to download JQuery library from http://jquery.com/ then load the jquery library the following way within your html head tags

then you can test whether the jquery is working by coding your jquery code after the jquery loading script

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<!--LINK JQUERY-->
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<!--PERSONAL SCRIPT JavaScript-->
<script type="text/javascript">
   $(function(){
      alert("My First Jquery Test");
   });
</script>

</head>
<body><!-- Your web--></body>
</html>

If you want to use your jquery scripts file seperately you must define the external .js file this way after the jquery library loading.

<script type="text/javascript" src="jquery-3.3.1.js"></script>
<script src="js/YourExternalJQueryScripts.js"></script>

Test in real time

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_

After reading the documentation of VideoCapture. I figured out that you can tell VideoCapture, which frame to process next time we call VideoCapture.read() (or VideoCapture.grab()).

The problem is that when you want to read() a frame which is not ready, the VideoCapture object stuck on that frame and never proceed. So you have to force it to start again from the previous frame.

Here is the code

import cv2

cap = cv2.VideoCapture("./out.mp4")
while not cap.isOpened():
    cap = cv2.VideoCapture("./out.mp4")
    cv2.waitKey(1000)
    print "Wait for the header"

pos_frame = cap.get(cv2.cv.CV_CAP_PROP_POS_FRAMES)
while True:
    flag, frame = cap.read()
    if flag:
        # The frame is ready and already captured
        cv2.imshow('video', frame)
        pos_frame = cap.get(cv2.cv.CV_CAP_PROP_POS_FRAMES)
        print str(pos_frame)+" frames"
    else:
        # The next frame is not ready, so we try to read it again
        cap.set(cv2.cv.CV_CAP_PROP_POS_FRAMES, pos_frame-1)
        print "frame is not ready"
        # It is better to wait for a while for the next frame to be ready
        cv2.waitKey(1000)

    if cv2.waitKey(10) == 27:
        break
    if cap.get(cv2.cv.CV_CAP_PROP_POS_FRAMES) == cap.get(cv2.cv.CV_CAP_PROP_FRAME_COUNT):
        # If the number of captured frames is equal to the total number of frames,
        # we stop
        break

Here's two newer potential solutions. Apparently, you can use jqtouch or pastrykit to disable scrolling. However, I haven't got these to work. You might be more competent.

turning off vertical scrolling

digging into pastrykit

This is what I ended up using. Temporarily sets target to _blank, then sets it back.

OnClientClick="var originalTarget = document.forms[0].target; document.forms[0].target = '_blank'; setTimeout(function () { document.forms[0].target = originalTarget; }, 3000);"

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

The way of dknaack does not work for me, I found this solution as well:

@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList, 
                    "Select chapter", new { @onchange = "location = this.value;" })

where

@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)

In the controller you can add:

DbModel db = new DbModel();    //entity model of Entity Framework

ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");

The preflight is being triggered by your Content-Type of application/json. The simplest way to prevent this is to set the Content-Type to be text/plain in your case. application/x-www-form-urlencoded & multipart/form-data Content-Types are also acceptable, but you'll of course need to format your request payload appropriately.

If you are still seeing a preflight after making this change, then Angular may be adding an X-header to the request as well.

Or you might have headers (Authorization, Cache-Control...) that will trigger it, see:

The Kotlin version of Pratik's utility method which dumps all extras of an Intent:

fun dumpIntent(intent: Intent) {

    val bundle: Bundle = intent.extras ?: return

    val keys = bundle.keySet()
    val it = keys.iterator()

    Log.d(TAG, "Dumping intent start")

    while (it.hasNext()) {
        val key = it.next()
        Log.d(TAG,"[" + key + "=" + bundle.get(key)+"]");
    }

    Log.d(TAG, "Dumping intent finish")

}
