I wrote this piece of code for object comparison, and it seems to work. check the assertions:

function countProps(obj) {
    var count = 0;
    for (k in obj) {
        if (obj.hasOwnProperty(k)) {
            count++;
        }
    }
    return count;
};

function objectEquals(v1, v2) {

    if (typeof(v1) !== typeof(v2)) {
        return false;
    }

    if (typeof(v1) === "function") {
        return v1.toString() === v2.toString();
    }

    if (v1 instanceof Object && v2 instanceof Object) {
        if (countProps(v1) !== countProps(v2)) {
            return false;
        }
        var r = true;
        for (k in v1) {
            r = objectEquals(v1[k], v2[k]);
            if (!r) {
                return false;
            }
        }
        return true;
    } else {
        return v1 === v2;
    }
}

assert.isTrue(objectEquals(null,null));
assert.isFalse(objectEquals(null,undefined));

assert.isTrue(objectEquals("hi","hi"));
assert.isTrue(objectEquals(5,5));
assert.isFalse(objectEquals(5,10));

assert.isTrue(objectEquals([],[]));
assert.isTrue(objectEquals([1,2],[1,2]));
assert.isFalse(objectEquals([1,2],[2,1]));
assert.isFalse(objectEquals([1,2],[1,2,3]));

assert.isTrue(objectEquals({},{}));
assert.isTrue(objectEquals({a:1,b:2},{a:1,b:2}));
assert.isTrue(objectEquals({a:1,b:2},{b:2,a:1}));
assert.isFalse(objectEquals({a:1,b:2},{a:1,b:3}));

assert.isTrue(objectEquals({1:{name:"mhc",age:28}, 2:{name:"arb",age:26}},{1:{name:"mhc",age:28}, 2:{name:"arb",age:26}}));
assert.isFalse(objectEquals({1:{name:"mhc",age:28}, 2:{name:"arb",age:26}},{1:{name:"mhc",age:28}, 2:{name:"arb",age:27}}));

assert.isTrue(objectEquals(function(x){return x;},function(x){return x;}));
assert.isFalse(objectEquals(function(x){return x;},function(y){return y+2;}));

Minor note: since Java 1.7 the Integer class has a static compare(Integer, Integer) method, so you can just call Integer.compare(x, y) and be done with it (questions about optimization aside).

Of course that code is incompatible with versions of Java before 1.7, so I would recommend using x.compareTo(y) instead, which is compatible back to 1.2.

In Expression Language you can just use the == or eq operator to compare object values. Behind the scenes they will actually use the Object#equals(). This way is done so, because until with the current EL 2.1 version you cannot invoke methods with other signatures than standard getter (and setter) methods (in the upcoming EL 2.2 it would be possible).

So the particular line

<c:when test="${lang}.equals(${pageLang})">

should be written as (note that the whole expression is inside the { and })

<c:when test="${lang == pageLang}">

or, equivalently

<c:when test="${lang eq pageLang}">

Both are behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals(jspContext.findAttribute("pageLang"))

If you want to compare constant String values, then you need to quote it

<c:when test="${lang == 'en'}">

or, equivalently

<c:when test="${lang eq 'en'}">

which is behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals("en")

You will have to override the equals function (along with others) to use this with custom classes.

The equals method compares the objects.

The == binary operator compares memory addresses.

I was also facing same problem but i renamed contact-form-7 plugin from /wp-content/plugins directory to contact-form-7-rename and problem solved.

So this is due to unsupportable plugins or theme.

use the below command as mention in other post to install tables again

mysql_install_db

For anyone who comes across this late, like me.

As others have stated, name isn't a valid attribute of an option element. Combining the accepted answer above with the answer from this other question, you get:

$(this).find('option:selected').text();

using System.ComponentModel.DataAnnotations.Schema;

[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime CreatedOn { get; private set; }

You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.

You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig. It will give out some information and your local IP should look like 192.168.1.x.

Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.my_drawable);

Context can be your current Activity.

For me put variable before calling did the trick:

Whatever Apple ships as the default gcc in xcode (4.2.1 on 10.6, 4.0.1 before) is well tested (and maintained) by the apple guys and the "standard" to build software with on OS X. Everything else is not, so think twice if you want to develop software, or be gcc/OS X beta tester.

Tried other variants, this can be proper

    Logger logger = Logger.getLogger(MyClass.class.getName());        
    Level level = Level.ALL;
    for(Handler h : java.util.logging.Logger.getLogger("").getHandlers())    
        h.setLevel(level);
    logger.setLevel(level);
// this must be shown
    logger.fine("fine");
    logger.info("info");

We can declare a two dimensional array and directly store elements at the time of its declaration as:

int marks[][]={{50,60,55,67,70},{62,65,70,70,81},{72,66,77,80,69}};

Here int represents integer type elements stored into the array and the array name is 'marks'. int is the datatype for all the elements represented inside the "{" and "}" braces because an array is a collection of elements having the same data type.

Coming back to our statement written above: each row of elements should be written inside the curly braces. The rows and the elements in each row should be separated by a commas.

Now observe the statement: you can get there are 3 rows and 5 columns, so the JVM creates 3 * 5 = 15 blocks of memory. These blocks can be individually referred ta as:

marks[0][0]  marks[0][1]  marks[0][2]  marks[0][3]  marks[0][4]
marks[1][0]  marks[1][1]  marks[1][2]  marks[1][3]  marks[1][4]
marks[2][0]  marks[2][1]  marks[2][2]  marks[2][3]  marks[2][4]

NOTE:
If you want to store n elements then the array index starts from zero and ends at n-1. Another way of creating a two dimensional array is by declaring the array first and then allotting memory for it by using new operator.

int marks[][];           // declare marks array
marks = new int[3][5];   // allocate memory for storing 15 elements

By combining the above two we can write:

int marks[][] = new int[3][5];

Fair warning about Apache POI's Excel generation... (I know this is an old post, but it's important in case someone looks this up again like I just did)

It had a memory leak issue, which supposedly was solved by 2006, but which people quite recently have still been experiencing. If you want to automate generating a large amount of excel (i.e., if you want to generate a single, large file, a large number of small files, or both), I'd recommend using a different API. Either that, or increasing the JVM stack size to preposterous proportions, and maybe looking into interning strings if you know you won't actually be working with many different strings (although, of course, interning strings means that if you have a large number of different strings, you'll have an entirely different program-crashing memory problem. So, consider that before you go that route).

Since you have mysql on your local computer, you do not need to bother with the IP address of the machine. Just use localhost:

mysql -u user -p

or

mysql -hlocalhost -u user -p

If you cannot login with this, you must find out what usernames (user@host) exist in the MySQL Server locallly. Here is what you do:

Step 01) Startup mysql so that no passwords are require no passwords and denies TCP/IP connections

service mysql restart --skip-grant-tables --skip-networking

Keep in mind that standard SQL for adding users, granting and revoking privs are disabled.

Step 02) Show users and hosts

select concat(''',user,'''@''',host,'''') userhost,password from mysql.user;

Step 03) Check your password to make sure it works

select user,host from mysql.user where password=password('YourMySQLPassword');

If your password produces no output for this query, you have a bad password.

If your password produces output for this query, look at the users and hosts. If your host value is '%', your should be able to connect from anywhere. If your host is 'localhost', you should be able to connect locally.

Make user you have 'root'@'localhost' defined.

Once you have done what is needed, just restart mysql normally

service mysql restart

If you are able to connect successfully on the macbook, run this query:

SELECT USER(),CURRENT_USER();

USER() reports how you attempted to authenticate in MySQL

CURRENT_USER() reports how you were allowed to authenticate in MySQL

Let us know what happens !!!

UPDATE 2012-02-13 20:47 EDT

Login to the remote server and repeat Step 1-3

See if any user allows remote access (i.e, host in mysql.user is '%'). If you do not, then add 'user'@'%' to mysql.user.

Just notice that if you work with Fragments using ViewPager, it's pretty easy. You only need to call this method: setOffscreenPageLimit().

Accordign to the docs:

Set the number of pages that should be retained to either side of the current page in the view hierarchy in an idle state. Pages beyond this limit will be recreated from the adapter when needed.

Similar issue here

You can try doing:

String myResource = IOUtils.toString(this.getClass().getResourceAsStream("yourfile.xml")).replace("\n","");

Implementation of seconds/minutes/hours, which are rails methods. Note that implicit returns aren't needed, but they look cleaner, so I prefer them. I'm not sure Rails even has .days or if it goes further, but these are the ones I need.

class Integer
   def seconds
      return self
   end
   def minutes
      return self * 60
   end
   def hours
      return self * 3600
   end
   def days
      return self * 86400
   end
end

After this, you can do: sleep 5.seconds to sleep for 5 seconds. You can do sleep 5.minutes to sleep for 5 min. You can do sleep 5.hours to sleep for 5 hours. And finally, you can do sleep 5.days to sleep for 5 days... You can add any method that return the value of self * (amount of seconds in that timeframe). As an exercise, try implementing it for months!

You can use

Restrictions.eqOrIsNull("status", status)

insted of

status == null ? Restrictions.isNull("status") : Restrictions.eq("status", status)

os.path.split is the function you are looking for

head, tail = os.path.split("/tmp/d/a.dat")

>>> print(tail)
a.dat
>>> print(head)
/tmp/d

I've found [DefaultValue] to be quite useful.

I usually expand each log out into it's own channel and then to a separate log file, certainly makes things easier when you are trying to debug specific issues. So my logging section looks like the following:

logging {

With the currently accepted solution you cannot print the page which contains the dialog itself anymore. Here's a much more dynamic solution:

JavaScript:

$().ready(function () {
    $('.modal.printable').on('shown.bs.modal', function () {
        $('.modal-dialog', this).addClass('focused');
        $('body').addClass('modalprinter');

        if ($(this).hasClass('autoprint')) {
            window.print();
        }
    }).on('hidden.bs.modal', function () {
        $('.modal-dialog', this).removeClass('focused');
        $('body').removeClass('modalprinter');
    });
});

CSS:

@media print {
    body.modalprinter * {
        visibility: hidden;
    }

    body.modalprinter .modal-dialog.focused {
        position: absolute;
        padding: 0;
        margin: 0;
        left: 0;
        top: 0;
    }

    body.modalprinter .modal-dialog.focused .modal-content {
        border-width: 0;
    }

    body.modalprinter .modal-dialog.focused .modal-content .modal-header .modal-title,
    body.modalprinter .modal-dialog.focused .modal-content .modal-body,
    body.modalprinter .modal-dialog.focused .modal-content .modal-body * {
        visibility: visible;
    }

    body.modalprinter .modal-dialog.focused .modal-content .modal-header,
    body.modalprinter .modal-dialog.focused .modal-content .modal-body {
        padding: 0;
    }

    body.modalprinter .modal-dialog.focused .modal-content .modal-header .modal-title {
        margin-bottom: 20px;
    }
}

Example:

<div class="modal fade printable autoprint">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body&hellip;</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary" onclick="window.print();">Print</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

For those of you running into the DirectoryNotFoundException, add this check:

if (Directory.Exists(path)) Directory.Delete(path, true);

** operator would be helpful here.

** operator will unpack the dict elements and thus **{'type':'Event'} would be treated as type='Event'

func(**{'type':'Event'}) is same as func(type='Event') i.e the dict elements would be converted to the keyword arguments.

FYI

* will unpack the list elements and they would be treated as positional arguments.

func(*['one', 'two']) is same as func('one', 'two')

$(window).unbind('scroll');

Even though the documentation says it will remove all event handlers if called with no arguments, it is worth giving a try explicitly unbinding it.

Update

It worked if you used single quotes? That doesn't sound right - as far as I know, JavaScript treats single and double quotes the same (unlike some other languages like PHP and C).

Try to update the below two parameters as they must be having default values.

innodb_lock_wait_timeout = 50

innodb_rollback_on_timeout = ON

For checking parameter value you can use the below SQL.

SHOW GLOBAL VARIABLES LIKE 'innodb_rollback_on_timeout';

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

yes, by the concept of pointer you can do it like this for an int variable:

int *a;
int b=0;
a=NULL; // or a=&b; for giving the value of b to a
if(a==NULL) 
  printf("NULL");
else
  printf(*a);

it is very simple and straitforward. it worked for me in Arduino IDE.

What I would do is comment out the Dockerfile below and including the offending line. Then you can run the container and run the docker commands by hand, and look at the logs in the usual way. E.g. if the Dockerfile is

RUN foo
RUN bar
RUN baz

and it's dying at bar I would do

RUN foo
# RUN bar
# RUN baz

Then

$ docker build -t foo .
$ docker run -it foo bash
container# bar
...grep logs...

Your CRON should look like this:

*/5 * * * *

CronWTF is really usefull when you need to test out your CRON settings.

Might be a good idea to pipe the output into a log file so you can see if your script is throwing any errors too - since you wont see them in your terminal.

Also try using a shebang at the top of your PHP file, so the system knows where to find PHP. Such as:

#!/usr/bin/php

that way you can call the whole thing like this

*/5 * * * * php /path/to/script.php > /path/to/logfile.log

Further refinig Sglasses method, the above lines force the use of SQLCMD mode, and either treminates the scirpt if not using SQLCMD mode or uses :on error exit to exit on any error
CONTEXT_INFO is used to keep track of the state.

SET CONTEXT_INFO  0x1 --Just to make sure everything's ok
GO 
--treminate the script on any error. (Requires SQLCMD mode)
:on error exit 
--If not in SQLCMD mode the above line will generate an error, so the next line won't hit
SET CONTEXT_INFO 0x2
GO
--make sure to use SQLCMD mode ( :on error needs that)
IF CONTEXT_INFO()<>0x2 
BEGIN
    SELECT CONTEXT_INFO()
    SELECT 'This script must be run in SQLCMD mode! (To enable it go to (Management Studio) Query->SQLCMD mode)\nPlease abort the script!'
    RAISERROR('This script must be run in SQLCMD mode! (To enable it go to (Management Studio) Query->SQLCMD mode)\nPlease abort the script!',16,1) WITH NOWAIT 
    WAITFOR DELAY '02:00'; --wait for the user to read the message, and terminate the script manually
END
GO

I was facing same problem.

When I rightclick-> run on server then select my server manually it worked.

Do

django.setup() in the top will not work while you are running a script explicitly. My problem solved when I added this in the bottom of the settings file

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
import sys
if BASE_DIR not in sys.path:
    sys.path.append(BASE_DIR)
os.environ['DJANGO_SETTINGS_MODULE'] =  "igp_lrpe.settings"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "igp_lrpe.settings")
import django
django.setup()

Use grep:

grep -wE "string1|String2|...." file_name

Or you can use:

echo string | grep -wE "string1|String2|...."

The content you're scraping is encoded in unicode rather than ascii text, and you're getting a character that doesn't convert to ascii. The right 'translation' depends on what the original web page thought it was. Python's unicode page gives the background on how it works.

Are you trying to print the result or stick it in a file? The error suggests it's writing the data that's causing the problem, not reading it. This question is a good place to look for the fixes.

To reorder the rows of a DataFrame just use a list as follows.

df = df[['Mid', 'Net', 'Upper', 'Lower', 'Zsore']]

This makes it very obvious what was done when reading the code later. Also use:

df.columns
Out[1]: Index(['Net', 'Upper', 'Lower', 'Mid', 'Zsore'], dtype='object')

Then cut and paste to reorder.

For a DataFrame with many columns, store the list of columns in a variable and pop the desired column to the front of the list. Here is an example:

cols = [str(col_name) for col_name in range(1001)]
data = np.random.rand(10,1001)
df = pd.DataFrame(data=data, columns=cols)

mv_col = cols.pop(cols.index('77'))
df = df[[mv_col] + cols]

Now df.columns has.

Index(['77', '0', '1', '2', '3', '4', '5', '6', '7', '8',
       ...
       '991', '992', '993', '994', '995', '996', '997', '998', '999', '1000'],
      dtype='object', length=1001)

There are various options are available to test which java version is using your eclipse. The best way is to find first java installed in your machine.

run java -version command on terminal

then to check whether your eclipse pointing to the right version or not.

For that go to

Eclipse >> Preferences >>Java >>Installed JREs

I would change your binding to be:

<button type="button" value="click me" onclick="check_me" />

I would then change your check_me() function declaration to be:

function check_me() {   
  //event.preventDefault();
  var hello = document.myForm.username.value;
  var err = '';

  if(hello == '' || hello == null) {
    err = 'User name required';
  }

  if(err != '') { 
     alert(err); 
     $('username').focus(); 
     event.preventDefault(); 
   } else { 
    return true; }
}

Django 2.1.1 The primary answer got me halfway to answering my question. It did not help me save the result to a field in my actual model. In my case I wanted a textfield that a user could enter data into, then when a save occurred the data would be processed and the result put into a field in the model and saved. While the original answer showed how to get the value from the extra field, it did not show how to save it back to the model at least in Django 2.1.1

This takes the value from an unbound custom field, processes, and saves it into my real description field:

class WidgetForm(forms.ModelForm):
    extra_field = forms.CharField(required=False)

    def processData(self, input):
        # example of error handling
        if False:
            raise forms.ValidationError('Processing failed!')

        return input + " has been processed"

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)

        # self.description = "my result" note that this does not work

        # Get the form instance so I can write to its fields
        instance = super(WidgetForm, self).save(commit=commit)

        # this writes the processed data to the description field
        instance.description = self.processData(extra_field)

        if commit:
            instance.save()

        return instance

    class Meta:
        model = Widget
        fields = "__all__"

That entity is converted to the char it represents when the browser renders the page. JS (jQuery) reads the rendered page, thus it will not encounter such a text sequence. The only way it could encounter such a thing is if you're double encoding entities.

With TypeScript generics you can do something like this.

class Person {
    constructor (public Name : string, public Age: number) {}
}

var list = new Array<Person>();
list.push(new Person("Baby", 1));
list.push(new Person("Toddler", 2));
list.push(new Person("Teen", 14));
list.push(new Person("Adult", 25));

var oldest_person = list.reduce( (a, b) => a.Age > b.Age ? a : b );
alert(oldest_person.Name);

I faced the same issue:

E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation

I resolved by using the following commands:

apt-get update
apt-get install gnupg

By default, IUSR account is used for anonymous user.

All you need to do is:

IIS -> Authentication --> Set Anonymous Authentication to Application Pool Identity.

Problem solved :)

Best way to Reset Password in Asp.Net Core Identity use for Web API.

Note* : Error() and Result() are created for internal use. You can return you want.

Assembly code is discussed here.

"An assembly language is a low-level language for programming computers. It implements a symbolic representation of the numeric machine codes and other constants needed to program a particular CPU architecture."

Machine code is discussed here.

"Machine code or machine language is a system of instructions and data executed directly by a computer's central processing unit."

Basically, assembler code is the language and it is translated to object code (the native code that the CPU runs) by an assembler (analogous to a compiler).

formatter = new SimpleDateFormat("dd-MMM-yy");

I think the best way is to store them in some yml file and then load that file using this command in intializer file

APP_CONFIG = YAML.load_file("#{Rails.root}/config/CONFIG.yml")[Rails.env].to_hash

you can easily access environment related config variables.

Your Yml file key value structure:

development:
  app_key: 'abc'
  app_secret: 'abc'

production:
  app_key: 'xyz'
  app_secret: 'ghq'

jQuery provides a .text() method that can be used in any browser. For example:

$('#myElement').text("Foo");

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

Try with:

select p from Person p left join FETCH p.address a where...

It works for me in a similar with JPA2/EclipseLink, but it seems this feature is present in JPA1 too:

No, it is not (Ruby 1.9.x)

require 'benchmark'

h = {"a"=>1, "c"=>3, "b"=>2, "d"=>4}
many = 100_000

Benchmark.bm do |b|
  GC.start

  b.report("hash sort") do
    many.times do
      Hash[h.sort]
    end
  end

  GC.start

  b.report("keys sort") do
    many.times do
      nh = {}
      h.keys.sort.each do |k|
        nh[k] = h[k]
      end
    end
  end
end

       user     system      total        real
hash sort  0.400000   0.000000   0.400000 (  0.405588)
keys sort  0.250000   0.010000   0.260000 (  0.260303)

For big hashes difference will grow up to 10x and more

You have to use the NotifyIcon control from System.Windows.Forms, or alternatively you can use the Notify Icon API provided by Windows API. WPF Provides no such equivalent, and it has been requested on Microsoft Connect several times.

I have code on GitHub which uses System.Windows.Forms NotifyIcon Component from within a WPF application, the code can be viewed at https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs

Here are the summary bits:

Create a WPF Window with ShowInTaskbar=False, and which is loaded in a non-Visible State.

At class-level:

private System.Windows.Forms.NotifyIcon notifyIcon = null;

During OnInitialize():

notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.Click += new EventHandler(notifyIcon_Click);
notifyIcon.DoubleClick += new EventHandler(notifyIcon_DoubleClick);
notifyIcon.Icon = IconHandles["QuickLaunch"];

During OnLoaded():

notifyIcon.Visible = true;

And for interaction (shown as notifyIcon.Click and DoubleClick above):

void notifyIcon_Click(object sender, EventArgs e)
{
    ShowQuickLaunchMenu();
}

From here you can resume the use of WPF Controls and APIs such as context menus, pop-up windows, etc.

It's that simple. You don't exactly need a WPF Window to host to the component, it's just the most convenient way to introduce one into a WPF App (as a Window is generally the default entry point defined via App.xaml), likewise, you don't need a WPF Wrapper or 3rd party control, as the SWF component is guaranteed present in any .NET Framework installation which also has WPF support since it's part of the .NET Framework (which all current and future .NET Framework versions build upon.) To date, there is no indication from Microsoft that SWF support will be dropped from the .NET Framework anytime soon.

Hope that helps.

It's a little cheese that you have to use a pre-3.0 Framework Component to get a tray-icon, but understandably as Microsoft has explained it, there is no concept of a System Tray within the scope of WPF. WPF is a presentation technology, and Notification Icons are an Operating System (not a "Presentation") concept.

the simplest way of solving the problem to begin with is copying latest version of hamcrest-code.jar into your CLASSPATH that is the file you store other .jar files needed for compilation and running of your application.

that could be e.g.: C:/ant/lib

I too got this problem and all solutions given above either failed or were not applicable due to client webservice restrictions.

For this, I added an iframe in my page which resided in the client;s server. So when we post our data to the iframe and the iframe then posts it to the webservice. Hence the cross-domain referencing is eliminated.

We added a 2-way origin check to confirm only authorized page posts data to and from the iframe.

Hope it helps

<iframe style="display:none;" id='receiver' name="receiver" src="https://iframe-address-at-client-server">
 </iframe>

//send data to iframe
var hiddenFrame = document.getElementById('receiver').contentWindow;
hiddenFrame.postMessage(JSON.stringify(message), 'https://client-server-url');

//The iframe receives the data using the code:
window.onload = function () {
    var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
    var eventer = window[eventMethod];
    var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
    eventer(messageEvent, function (e) {
        var origin = e.origin;
        //if origin not in pre-defined list, break and return
        var messageFromParent = JSON.parse(e.data);
        var json = messageFromParent.data;

        //send json to web service using AJAX   
        //return the response back to source
        e.source.postMessage(JSON.stringify(aJAXResponse), e.origin);
    }, false);
}

You could just use a HashSet<String> to maintain a collection of unique objects. If the Integer values in your map are important, then you can instead use the containsKey method of maps to test whether your key is already in the map.

You can pass PHP values to JavaScript. The PHP will execute server side so the value will be calculated and then you can echo it to the HTML containing the javascript. The javascript will then execute in the clients browser with the value PHP calculated server-side.

<script type="text/javascript">
    // Do something in JavaScript
    var x = <?php echo $calculatedValue; ?>;
    // etc..
</script>

Here's a way to hide it, without ruining the default padding:

fun View.setViewBackgroundWithoutResettingPadding(background: Drawable?) {
    val paddingBottom = this.paddingBottom
    val paddingStart = ViewCompat.getPaddingStart(this)
    val paddingEnd = ViewCompat.getPaddingEnd(this)
    val paddingTop = this.paddingTop
    ViewCompat.setBackground(this, background)
    ViewCompat.setPaddingRelative(this, paddingStart, paddingTop, paddingEnd, paddingBottom)
}

usage:

editText.setViewBackgroundWithoutResettingPadding(null)

Update:

If you find yourself always passing null, you can codify that in the method (and then you might as well overload EditText itself)

fun EditText.removeUnderline() {
    val paddingBottom = this.paddingBottom
    val paddingStart = ViewCompat.getPaddingStart(this)
    val paddingEnd = ViewCompat.getPaddingEnd(this)
    val paddingTop = this.paddingTop
    ViewCompat.setBackground(this, null)
    ViewCompat.setPaddingRelative(this, paddingStart, paddingTop, paddingEnd, paddingBottom)
}

// usage:
editText.removeUnderline()

In my workflow, I add a Dockerfile for each part of my system and configure it that each part could run individually. Then I add a docker-compose.yml to bring them together and link them.

Biggest advantage (in my opinion): when linking the containers, you can define a name and ping your containers with this name. Therefore your database might be accessible with the name db and no longer by its IP.

I believe IE requires the H.264 or MPEG-4 codec, which it seems like you don't specify/include. You can always check for browser support by using HTML5Please and Can I use.... Both sites usually have very up-to-date information about support, polyfills, and advice on how to take advantage of new technology.

\includegraphics<1>{A}%
\includegraphics<2>{B}%
\includegraphics<3>{C}%

The % is important. This will keep all the images fixed.

If you are using foreach inside a function and you are expecting an array or a Traversable object you can type hint that function with:

function myFunction(array $a)
function myFunction(Traversable)

If you are not using foreach inside a function or you are expecting both you can simply use this construct to check if you can iterate over the variable:

if (is_array($a) or ($a instanceof Traversable))

Increment and decrement by 10.

require(Hmisc)
inc(x) <- 10 

dec(x) <- 10

python3 -m pip install --user --upgrade pip==9.0.3

pip issue: rollback

above my knowledge it is possible in 4 ways

1. HTML<button style="display:none;"></button>
2. CSS #buttonId{ display:none; }
3. jQuery $('#buttonId').prop('display':'none'); & $("#buttonId").css('opacity', 0);

This error is probably related to a byte order mark (BOM) prior to the actual XML content. You need to parse the returned String and discard the BOM, so SAXParser can process the document correctly.

You will find a possible solution here.

You can take a reference on the control on the ItemCreated event, and then use it later.

In addition to setting the registry entry for AuthServerWhitelist you should also set AuthSchemes: "ntlm,negotiate" (or just "ntlm" as appropriate for your situation). Using the above templates the policy for that will be "Supported authentication schemes"

Remove warnings.filterwarnings and add:

This will be in synchronisation with an api call, When the api call is triggered, the loader is shown. When the api call is succesful, the loader is removed. This can be used for either page load or during an api call.

I believe there is a better solution than rewrite the RegistrationsController. I did exactly the same thing (I just have Organization instead of Company).

If you set properly your nested form, at model and view level, everything works like a charm.

My User model:

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable, :lockable and :timeoutable
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable

  has_many :owned_organizations, :class_name => 'Organization', :foreign_key => :owner_id

  has_many :organization_memberships
  has_many :organizations, :through => :organization_memberships

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :name, :username, :owned_organizations_attributes

  accepts_nested_attributes_for :owned_organizations
  ...
end

My Organization Model:

class Organization < ActiveRecord::Base
  belongs_to :owner, :class_name => 'User'
  has_many :organization_memberships
  has_many :users, :through => :organization_memberships
  has_many :contracts

  attr_accessor :plan_name

  after_create :set_owner_membership, :set_contract
  ...
end

My view : 'devise/registrations/new.html.erb'

Use SVN repository URL to export file to Local path.

     svn export [-r rev] [--ignore-externals] URL Export_PATH
     svn export http://<path>/test.txt C:\Temp-Folder

You might use Form tag with action attribute to submit the mailto.

Here is an example:

<form method="post" action="mailto:[email protected]" >
<input type="submit" value="Send Email" /> 
</form>

As Tim Potter pointed out, setting proxy in dockerfile is horrible. When building the image, you add proxy for your corporate network but you may be deploying in cloud or a DMZ where there is no need for proxy or the proxy server is different.

Also, you cannot share your image with others outside your corporate n/w.

Assuming you're using cookies for login, just call it after your setcookie call -- after all, you must be calling that one before any output too.

Anyway in general you could check for the presence of your form's submit button name at the beginning of the script, do your logic, and then output stuff:

if(isset($_POST['mySubmit'])) {
    // the form was submitted

    // ...
    // perform your logic

    // redirect if login was successful
    header('Location: /somewhere');
}

// output your stuff here

It's either through system property

-Dorg.slf4j.simpleLogger.defaultLogLevel=debug

or simplelogger.properties file on the classpath

In spark version >= 3 you can convert pandas dataframes to pyspark dataframe in one line

use spark.createDataFrame(pandasDF)

dataset = pd.read_csv("data/AS/test_v2.csv")

sparkDf = spark.createDataFrame(dataset);

if you are confused about spark session variable, spark session is as follows

sc = SparkContext.getOrCreate(SparkConf().setMaster("local[*]"))

spark = SparkSession \
    .builder \
    .getOrCreate()

        Log.w(TAG, e.getMessage());
    }
}

This methos is just pick up a dialog and if user wants install the external application from market

private void showInstallResultMessage(int msg_id) {
    AlertDialog dialog = new AlertDialog.Builder(this).create();
    dialog.setMessage(getText(msg_id));
    dialog.setButton(getText(R.string.button_ok),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });
    dialog.setButton2(getText(R.string.button_install),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
                    startActivity(intent);
                    finish();
                }
            });
    dialog.show();
}

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

Based on CQM's answer and on ovokerie-ogbeta's answer to another question I've come up with this solution:

if (colorAsString.length() == 4) { // #XXX
    colorAsString = colorAsString.replaceAll("#([0-9a-fA-F])([0-9a-fA-F])([0-9a-fA-F])", "#$1$1$2$2$3$3");
}

int color = Color.parseColor(colorAsString);

If anyone wonders, Drawnonward's solution would look like this in Swift:

func webView(webView: UIWebView!, shouldStartLoadWithRequest request: NSURLRequest!, navigationType: UIWebViewNavigationType) -> Bool {
    if navigationType == UIWebViewNavigationType.LinkClicked {
        UIApplication.sharedApplication().openURL(request.URL)
        return false
    }
    return true
}

 log4j.rootLogger=OFF

Update: Yes, I understand that this answer does not explain the difference between arm64 and armhf. There is a great answer that does explain that on this page. This answer was intended to help set the asker on the right path, as they clearly had a misunderstanding about the capabilities of the Raspberry Pi at the time of asking.

Where are you seeing that the architecture is armhf? On my Raspberry Pi 3, I get:

$ uname -a
armv7l

Anyway, armv7 indicates that the system architecture is 32-bit. The first ARM architecture offering 64-bit support is armv8. See this table for reference.

You are correct that the CPU in the Raspberry Pi 3 is 64-bit, but the Raspbian OS has not yet been updated for a 64-bit device. 32-bit software can run on a 64-bit system (but not vice versa). This is why you're not seeing the architecture reported as 64-bit.

You can follow the GitHub issue for 64-bit support here, if you're interested.

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob; 


 "I have finished inputting your clob: 60030"

How about PropertiesLoaderUtils?

Resource resource = new ClassPathResource("/my.properties");
Properties props = PropertiesLoaderUtils.loadProperties(resource);

Assertj is good at this.

import static org.assertj.core.api.Assertions.assertThat;

    assertThat(myClass.getMyItems()).extracting("name").contains("foo", "bar");

Big plus for assertj compared to hamcrest is easy use of code completion.

There are several useful answers, but none seem to cover all the latest options. To that end all my examples also cater for the presence of matching label elements and also allow you to dynamically add checkboxes and see the results in a side-panel (by redirecting console.log).

• Listening for click events on checkboxes is not a good idea as that will not allow for keyboard toggling or for changes made where a matching label element was clicked. Always listen for the change event.

• Use the jQuery :checkbox pseudo-selector, rather than input[type=checkbox]. :checkbox is shorter and more readable.

• Use is() with the jQuery :checked pseudo-selector to test for whether a checkbox is checked. This is guaranteed to work across all browsers.

Basic event handler attached to existing elements:

$('#myform :checkbox').change(function () {
    if ($(this).is(':checked')) {
        console.log($(this).val() + ' is now checked');
    } else {
        console.log($(this).val() + ' is now unchecked');
    }
});

JSFiddle: http://jsfiddle.net/TrueBlueAussie/u8bcggfL/2/

Notes:

• Uses the :checkbox selector, which is preferable to using input[type=checkbox]
• This connects only to matching elements that exist at the time the event was registered.

Delegated event handler attached to ancestor element:

Delegated event handlers are designed for situations where the elements may not yet exist (dynamically loaded or created) and is very useful. They delegate responsibility to an ancestor element (hence the term).

$('#myform').on('change', ':checkbox', function () {
    if ($(this).is(':checked')) {
        console.log($(this).val() + ' is now checked');
    } else {
        console.log($(this).val() + ' is now unchecked');
    }
});

JSFiddle: http://jsfiddle.net/TrueBlueAussie/u8bcggfL/4/

Notes:

• This works by listening for events (in this case change) to bubble up to a non-changing ancestor element (in this case #myform).
• It then applies the jQuery selector (':checkbox' in this case) to only the elements in the bubble chain.
• It then applies the event handler function to only those matching elements that caused the event.
• Use document as the default to connect the delegated event handler, if nothing else is closer/convenient.
• Do not use body to attach delegated events as it has a bug (to do with styling) that can stop it getting mouse events.

The upshot of delegated handlers is that the matching elements only need to exist at event time and not when the event handler was registered. This allows for dynamically added content to generate the events.

Q: Is it slower?

A: So long as the events are at user-interaction speeds, you do not need to worry about the negligible difference in speed between a delegated event handler and a directly connected handler. The benefits of delegation far outweigh any minor downside. Delegated event handlers are actually faster to register as they typically connect to a single matching element.

Why doesn't prop('checked', true) fire the change event?

This is actually by design. If it did fire the event you would easily get into a situation of endless updates. Instead, after changing the checked property, send a change event to the same element using trigger (not triggerHandler):

e.g. without trigger no event occurs

$cb.prop('checked', !$cb.prop('checked'));

JSFiddle: http://jsfiddle.net/TrueBlueAussie/u8bcggfL/5/

e.g. with trigger the normal change event is caught

$cb.prop('checked', !$cb.prop('checked')).trigger('change');

JSFiddle: http://jsfiddle.net/TrueBlueAussie/u8bcggfL/6/

Notes:

• Do not use triggerHandler as was suggested by one user, as it will not bubble events to a delegated event handler.

JSFiddle: http://jsfiddle.net/TrueBlueAussie/u8bcggfL/8/

although it will work for an event handler directly connected to the element:

JSFiddle: http://jsfiddle.net/TrueBlueAussie/u8bcggfL/9/

Events triggered with .triggerHandler() do not bubble up the DOM hierarchy; if they are not handled by the target element directly, they do nothing.

Reference: http://api.jquery.com/triggerhandler/

If anyone has additional features they feel are not covered by this, please do suggest additions.

You can also send an array via FormData this way:

var formData = new FormData;
var arr = ['this', 'is', 'an', 'array'];
for (var i = 0; i < arr.length; i++) {
    formData.append('arr[]', arr[i]);
}

So you can write arr[] the same way as you do it with a simple HTML form. In case of PHP it should work.

You may find this article useful: How to pass an array within a query string?

You can also sometimes get this error if you try to decrypt a secret while su-ed to a different user on a system with GPG 2.x installed. This bug has been reported against RHEL 6 but there is no fix available; apparently this is due to some design decisions in GPG 2.x. One workaround suggested in the bug report is to run the decryption inside of a tmux or screen session. More reading here.

Your decision should be based on

• your actual need for these "more features"; and
• your expected cost of implementing the change.

You should resist the urge to change APIs just because it's "newer, shinier, better." I follow a policy of "if it's not broken, don't kick it."

If your application requires a very sophisticated logging framework, you may want to consider why.

I have already do this :

1) Window -> Preferences -> General -> Network Connections. I put in Manual with the url and port of my proxy for HTTP protocol. It works because before this, Spring Tool Suite did not want to update. After, it's okay.

2) Window -> Preferences -> Maven -> User Settings. In Global Settings, is empty. In User Settings, I put the path to settings.xml. In this file, i have :

Take a look at

$id = strrchr($url,"/");
$id = substr($id,1,strlen($id));

Here is the description of the strrchr function: http://www.php.net/manual/en/function.strrchr.php

Hope that's useful!

Ignoring anything else that may or may not be correct with your "revised code", the issue causing the error currently quoted in your question is caused by calling the "count" function with an undefined variable because your didn't quote the string.

• count(thisisastring222) looks for a variable called thisisastring222 to pass to the function called count. For this to work you would have to have defined the variable earlier (e.g. with thisisastring222 = "AStringWith1NumberInIt.") then your function will do what you want with the contents of the value stored in the variable, not the name of the variable.
• count("thisisastring222") hardcodes the string "thisisastring222" into the call, meaning that the count function will work with the exact string passed to it.

To fix your call to your function, just add quotes around asdfkasdflasdfl222 changing count(asdfkasdflasdfl222) to count("asdfkasdflasdfl222").

As far as the actual question "How to count digits, letters, spaces for a string in Python", at a glance the rest of the "revised code" looks OK except that the return line is not returning the same variables you've used in the rest of the code. To fix it without changing anything else in the code, change number and word to digit and letters, making return number,word,space,other into return digit,letters,space,other, or better yet return (digit, letters, space, other) to match current behavior while also using better coding style and being explicit as to what type of value is returned (in this case, a tuple).

Actually you are right: it runs another instance of make. A possible solution would be:

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : clean clearscr all

clearscr:
    clear

By calling make fresh you get first the clean target, then the clearscreen which runs clear and finally all which does the job.

EDIT Aug 4

What happens in the case of parallel builds with make’s -j option? There's a way of fixing the order. From the make manual, section 4.2:

Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites

The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).

Hence the makefile becomes

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : | clean clearscr all

clearscr:
    clear

EDIT Dec 5

It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.

log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)

install:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  command1  # this line will be a subshell
  command2  # this line will be another subshell
  @command3  # Use `@` to hide the command line
  $(call log_error, "It works, yey!")

uninstall:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  ....
  $(call log_error, "Nuked!")

I also needed what you've been searching for and did some research.

I found JSC3D (https://code.google.com/p/jsc3d/). It's a project written entirely in Javascript and uses the HTML canvas. It has been tested for Opera, Chrome, Firefox, Safari, IE9 and more.

Then you have services as p3d.in and Sketchfab that give you a nice reader to view 3D models on a web page: they use HTML5 and WebGL. They both have a free version.

Normally you should use __cplusplus define to detect c++17, but by default microsoft compiler does not define that macro properly, see https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/ - you need to either modify project settings to include /Zc:__cplusplus switch, or you could use syntax like this:

#if ((defined(_MSVC_LANG) && _MSVC_LANG >= 201703L) || __cplusplus >= 201703L)
     //C++17 specific stuff here
#endif

In a shell, & is a special character, advising the shell to start everything up to the & as a process in the background. To avoid this behavior, you can put the URL in quotes. See the youtube-dl FAQ for more information.

Also beware of -citk. With the exception of -i, these options make little sense. See the youtube-dl FAQ for more information. Even -f mp4 looks very strange.

So what you want is:

youtube-dl -i -f mp4 --yes-playlist 'https://www.youtube.com/watch?v=7Vy8970q0Xc&list=PLwJ2VKmefmxpUJEGB1ff6yUZ5Zd7Gegn2'

Alternatively, you can just use the playlist ID:

youtube-dl -i PLwJ2VKmefmxpUJEGB1ff6yUZ5Zd7Gegn2

There are many ways to write html with JavaScript.

document.write is only useful when you want to write to page before it has actually loaded. If you use document.write() after the page has loaded (at onload event) it will create new page and overwrite the old content. Also it doesn't work with XML, that includes XHTML.

From other hand other methods can't be used before DOM has been created (page loaded), because they work directly with DOM.

These methods are:

• node.innerHTML = "Whatever";
• document.createElement('div'); and node.appendChild(), etc..

In most cases node.innerHTML is better since it's faster then DOM functions. Most of the time it also make code more readable and smaller.

StrSubstitutor from Apache Commons Lang may be used for string formatting with named placeholders:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-text</artifactId>
    <version>1.1</version>
</dependency>

https://commons.apache.org/proper/commons-lang/javadocs/api-3.4/org/apache/commons/lang3/text/StrSubstitutor.html :

Substitutes variables within a string by values.

This class takes a piece of text and substitutes all the variables within it. The default definition of a variable is ${variableName}. The prefix and suffix can be changed via constructors and set methods.

Variable values are typically resolved from a map, but could also be resolved from system properties, or by supplying a custom variable resolver.

Example:

String template = "Hi ${name}! Your number is ${number}";

Map<String, String> data = new HashMap<String, String>();
data.put("name", "John");
data.put("number", "1");

String formattedString = StrSubstitutor.replace(template, data);

I personally really like icdiff !

If you're on Mac OS X with HomeBrew, just do brew install icdiff.

To get the file labels correctly, plus other cool features, I have in my ~/.gitconfig:

[pager]
    difftool = true
[diff]
    tool = icdiff
[difftool "icdiff"]
    cmd = icdiff --head=5000 --highlight --line-numbers -L \"$BASE\" -L \"$REMOTE\" \"$LOCAL\" \"$REMOTE\"

And I use it like: git difftool

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

based on :

https://stackoverflow.com/a/10104037/878126

Alternatively, while in your screen session all you have to do is type exit

This will kill the shell session initiated by the screen, which effectively terminates the screen session you are on.

No need to bother with screen session id, etc.

One way to fix it is by modifying the assembly redirect in the web.config file.

Modify the following:

<dependentAssembly>
        <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>

to

<dependentAssembly>
        <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="4.0.0.0" />
</dependentAssembly>

So the oldVersion attribute should change from "...-4.0.0.0" to "...-5.2.3.0".

One can also use blending:

im1 = Image.open("im1.png")
im2 = Image.open("im2.png")
blended = Image.blend(im1, im2, alpha=0.5)
blended.save("blended.png")

if (e.preventDefault) {
    e.preventDefault();
} else {
    e.returnValue = false;
}

Tested on IE 9 and Chrome.

I'd be careful about trying to get too clever here. I think it's confusing as it is and using more advanced nth-child parameters will only make it more complicated. As for the background color I'd just set that to a variable.

Here goes what I came up with before I realized trying to be too clever might be a bad thing.

#romtest {
 $bg: #e5e5e5;
 .detailed {
    th {
      &:nth-child(-2n+6) {
        background-color: $bg;
      }
    }
    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        background-color: $bg;
      }
      &.last {
        &:nth-child(-2n+4){
          background-color: $bg;
        }
      }
    }
  }
}

and here is a quick demo: http://codepen.io/anon/pen/BEImD

----EDIT----

Here's another approach to avoid retyping background-color:

#romtest {
  %highlight {
    background-color: #e5e5e5; 
  }
  .detailed {
    th {
      &:nth-child(-2n+6) {
        @extend %highlight;
      }
    }

    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        @extend %highlight;
      }
      &.last {
        &:nth-child(-2n+4){
          @extend %highlight;
        }
      }
    }
  }
}

After having used Waterboy's code over and over in multiple Python packages, I finally cast it into a tiny standalone Python package, which you can find here:

https://github.com/acschaefer/duallog

The code is well documented and easy to use. Simply download the .py file and include it in your project, or install the whole package via pip install duallog.

The reason that does not work is because this has no specific meaning inside of an if statement, you will have to go back to a level of scope where this is defined (a function).

For example:

$('#element1').click(function() {
    console.log($(this).attr('id')); // logs "element1"

    if ($('#element2').hasClass('class')) {
        console.log($(this).attr('id')); // still logs "element1"
    }
});

In python 3.7 and above there is a new and easy way. here is the syntax:

name = "Eric"
age = 74
f"Hello, {name}. You are {age}."

OutPut:

Hello, Eric. You are 74.

Assuming you mean "list" where you say "array", you can do

if item in my_list:
    # whatever

This works for any collection, not just for lists. For dictionaries, it checks whether the given key is present in the dictionary.

This question has not enough information to answer. A general solution (depending on your GUI framework): add a mouse event handler that will catch clicks and mouse movements. This will give you your (x, y) coordinates. Next use these coordinates to crop your image.

The accepted answer gave me a good start, but brought in more classes and more processing than I would have liked; so this is my interpretation:

$xml_reader = new XMLReader;
$xml_reader->open($feed_url);

// move the pointer to the first product
while ($xml_reader->read() && $xml_reader->name != 'product');

// loop through the products
while ($xml_reader->name == 'product')
{
    // load the current xml element into simplexml and we’re off and running!
    $xml = simplexml_load_string($xml_reader->readOuterXML());

    // now you can use your simpleXML object ($xml).
    echo $xml->element_1;

    // move the pointer to the next product
    $xml_reader->next('product');
}

// don’t forget to close the file
$xml_reader->close();

Note that it may be better use subdomains instead of usual URL. So, set .example.com instead of https://example.com/.

Thanks to Jody Jacobus Geers and others I wrote so:

if (savedInstanceState == null) {
    val cookieManager = CookieManager.getInstance()
    cookieManager.acceptCookie()
    val domain = ".example.com"
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        cookieManager.setCookie(domain, "token=$token") {
            view.webView.loadUrl(url)
        }
        cookieManager.setAcceptThirdPartyCookies(view.webView, true)
    } else {
        cookieManager.setCookie(domain, "token=$token")
        view.webView.loadUrl(url)
    }
} else {
    // Check whether we're recreating a previously destroyed instance.
    view.webView.restoreState(savedInstanceState)
}

Yes, it will throw an Exception. maybe you are used to PHP code, where empty($element) does also check for isset($element)? In Java this is not the case.

You can memorize that easily because the method is directly called on the list (the method belongs to the list). So if there is no list, then there is no method. And Java will complain that there is no list to call this method on.

A blanket "no you shouldn't" is terrible advice. This is perfectly reasonable in many situations depending on your use case, workload, data entropy, hardware, etc.. What you shouldn't do is make assumptions.

It should be noted that you can specify a prefix which will limit MySQL's indexing, thereby giving you some help in narrowing down the results before scanning the rest. This may, however, become less useful over time as your prefix "fills up" and becomes less unique.

It's very simple to do, e.g.:

CREATE TABLE IF NOT EXISTS `foo` (
  `id` varchar(128),
  PRIMARY KEY (`id`(4))
)

Also note that the prefix (4) appears after the column quotes. Where the 4 means that it should use the first 4 characters of the 128 possible characters that can exist as the id.

Lastly, you should read how index prefixes work and their limitations before using them: https://dev.mysql.com/doc/refman/8.0/en/create-index.html

The documentation is here: http://docs.jquery.com/Ajax/jQuery.ajax

But, to summarize, the ajax call takes a bunch of options. the ones you are looking for are error and success.

You would call it like this:

$.ajax({
  url: 'mypage.html',
  success: function(){
    alert('success');
  },
  error: function(){
    alert('failure');

});

I have shown the success and error function taking no arguments, but they can receive arguments.

The error function can take three arguments: XMLHttpRequest, textStatus, and errorThrown.

The success function can take two arguments: data and textStatus. The page you requested will be in the data argument.

Meanwhile, all the values above will only restrict the values to integer, so i use

/^[1-9][0-9\.]{0,15}$/

to allow float values too.

ary.GetLength(1)

The programming language doesn't matter; measuring the runtime complexity of an algorithm works the same way regardless of the language. Analysis of Algorithms by Stanford on Google Code University is a very good resource for teaching yourself how to analyze the runtime complexity of algorithms and code.

If all you want to do is measure the elapsed time that a function or section of code took to run in Python, then you can use the timeit or time modules, depending on how long the code needs to run.

If there isn't a pressing need to use images for the separators, you could do this with pure CSS.

nav li + li:before{
    content: " | ";
    padding: 0 10px;
}

This puts a bar between each list item, just as the image in the original question described. But since we're using the adjacent selectors, it doesn't put the bar before the first element. And since we're using the :before pseudo selector, it doesn't put one at the end.

__all__ customizes * in from <module> import *

__all__ customizes * in from <package> import *

A module is a .py file meant to be imported.

A package is a directory with a __init__.py file. A package usually contains modules.

MODULES

""" cheese.py - an example module """

__all__ = ['swiss', 'cheddar']

swiss = 4.99
cheddar = 3.99
gouda = 10.99

__all__ lets humans know the "public" features of a module.^[@AaronHall] Also, pydoc recognizes them.^[@Longpoke]

from module import *

See how swiss and cheddar are brought into the local namespace, but not gouda:

>>> from cheese import *
>>> swiss, cheddar
(4.99, 3.99)
>>> gouda
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'gouda' is not defined

Without __all__, any symbol (that doesn't start with an underscore) would have been available.

Imports without * are not affected by __all__

import module

>>> import cheese
>>> cheese.swiss, cheese.cheddar, cheese.gouda
(4.99, 3.99, 10.99)

from module import names

>>> from cheese import swiss, cheddar, gouda
>>> swiss, cheddar, gouda
(4.99, 3.99, 10.99)

import module as localname

>>> import cheese as ch
>>> ch.swiss, ch.cheddar, ch.gouda
(4.99, 3.99, 10.99)

PACKAGES

In the __init__.py file of a package __all__ is a list of strings with the names of public modules or other objects. Those features are available to wildcard imports. As with modules, __all__ customizes the * when wildcard-importing from the package.^{[@MartinStettner]}

Here's an excerpt from the Python MySQL Connector __init__.py:

__all__ = [
    'MySQLConnection', 'Connect', 'custom_error_exception',

    # Some useful constants
    'FieldType', 'FieldFlag', 'ClientFlag', 'CharacterSet', 'RefreshOption',
    'HAVE_CEXT',

    # Error handling
    'Error', 'Warning',

    ...etc...

    ]

The default case, asterisk with no __all__ for a package, is complicated, because the obvious behavior would be expensive: to use the file system to search for all modules in the package. Instead, in my reading of the docs, only the objects defined in __init__.py are imported:

If __all__ is not defined, the statement from sound.effects import * does not import all submodules from the package sound.effects into the current namespace; it only ensures that the package sound.effects has been imported (possibly running any initialization code in __init__.py) and then imports whatever names are defined in the package. This includes any names defined (and submodules explicitly loaded) by __init__.py. It also includes any submodules of the package that were explicitly loaded by previous import statements.

And lastly, a venerated tradition for stack overflow answers, professors, and mansplainers everywhere, is the bon mot of reproach for asking a question in the first place:

Wildcard imports ... should be avoided, as they [confuse] readers and many automated tools.

^{[PEP 8, @ToolmakerSteve]}

Generally you cannot translate from a time zone like Asia/Kolkata to a GMT offset like +05:30 or +07:00. A time zone, as the name says, is a place on earth and comprises the historic, present and known future UTC offsets used by the people in that place (for now we can regard GMT and UTC as synonyms, strictly speaking they are not). For example, Asia/Kolkata has been at offset +05:30 since 1945. During periods between 1941 and 1945 it was at +06:30 and before that time at +05:53:20 (yes, with seconds precision). Many other time zones have summer time (daylight saving time, DST) and change their offset twice a year.

Given a point in time, we can make the translation for that particular point in time, though. I should like to provide the modern way of doing that.

java.time and ThreeTenABP

    ZoneId zone = ZoneId.of("Asia/Kolkata");

    ZoneOffset offsetIn1944 = LocalDateTime.of(1944, Month.JANUARY, 1, 0, 0)
            .atZone(zone)
            .getOffset();
    System.out.println("Offset in 1944: " + offsetIn1944);

    ZoneOffset offsetToday = OffsetDateTime.now(zone)
            .getOffset();
    System.out.println("Offset now: " + offsetToday);

Output when running just now was:

Offset in 1944: +06:30
Offset now: +05:30

For the default time zone set zone to ZoneId.systemDefault().

To format the offset with the text GMT use a formatter with OOOO (four uppercase letter O) in the pattern:

    DateTimeFormatter offsetFormatter = DateTimeFormatter.ofPattern("OOOO");
    System.out.println(offsetFormatter.format(offsetToday));

GMT+05:30

I am recommending and in my code I am using java.time, the modern Java date and time API. The TimeZone, Calendar, Date, SimpleDateFormat and DateFormat classes used in many of the other answers are poorly designed and now long outdated, so my suggestion is to avoid all of them.

Question: Can I use java.time on Android?

Yes, java.time works nicely on older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

Depends on your use case.

If you want to do some animation of children blending in, use the react animation add-on: https://facebook.github.io/react/docs/animation.html Otherwise, make the rendering of the children dependent on props and add the props after some delay.

I wouldn't delay in the component, because it will probably haunt you during testing. And ideally, components should be pure.

Include js files of datepicker and language (locales)

'resource/bower_components/bootstrap-datepicker/dist/js/bootstrap-datepicker.min.js',
'resource/bower_components/bootstrap-datepicker/dist/locales/bootstrap-datepicker.sv.min.js',

In the options of the datepicker, set the language as below:

$('.datepicker').datepicker({'language' : 'sv'});

Column values from the SELECT statement are assigned into @low and @day local variables; the @adjustedLow value is not assigned into any variable and it causes the problem:

The problem is here:

select 
    top 1 @low = low
    , @day = day
    , @adjustedLow  -- causes error!
--select high
from 
    securityquote sq

This is a known bug on the initial 2.5.1, and has been fixed in early 2007 (Redhat 2.5.1-5) according to the bug reports. Unfortunately Apple is still using 2.5.1 even on Mac OS X 10.7.2.

You could get a newer version via Homebrew (3.0) or MacPorts (2.26) or fink (3.0-1).

Edit: Apparently it has been fixed on OS X 10.11 (or maybe earlier), even though the grep version reported is still 2.5.1.

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. But i think ini_set() helps you to change the values in php.ini during run time.

Here's the function I use:

template<typename T>
static void setValue(T arr[], size_t length, const T& val)
{
    std::fill(arr, arr + length, val);
}

template<typename T, size_t N>
static void setValue(T (&arr)[N], const T& val)
{
    std::fill(arr, arr + N, val);
}

You can call it like this:

//fixed arrays
int a[10];
setValue(a, 0);

//dynamic arrays
int *d = new int[length];
setValue(d, length, 0);

Above is more C++11 way than using memset. Also you get compile time error if you use dynamic array with specifying the size.

You can concat many kind of expression by sorrounding your simple/complex expression between || characters:

<p th:text="|${bean.field} ! ${bean.field}|">Static content</p>

Way 1: only works for dataURL, not for other types of url.

function dataURLtoFile(dataurl, filename) {
    var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
        bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
    while(n--){
        u8arr[n] = bstr.charCodeAt(n);
    }
    return new File([u8arr], filename, {type:mime});
}

//Usage example:
var file = dataURLtoFile('data:image/png;base64,......', 'a.png');
console.log(file);

Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)

//return a promise that resolves with a File instance
function urltoFile(url, filename, mimeType){
    mimeType = mimeType || (url.match(/^data:([^;]+);/)||'')[1];
    return (fetch(url)
        .then(function(res){return res.arrayBuffer();})
        .then(function(buf){return new File([buf], filename, {type:mimeType});})
    );
}

//Usage example:
urltoFile('data:image/png;base64,......', 'a.png')
.then(function(file){
    console.log(file);
})

Both works in Chrome and Firefox.

you can use regex in order to catch any length of white space, and this would be like:

var text = "hoi how     are          you";
var arr = text.split(/\s+/);

console.log(arr) // will result : ["hoi", "how", "are", "you"]

console.log(arr[2]) // will result : "are" 

<?php 
 $current = strtotime(date("Y-m-d"));
 $date    = strtotime("2014-09-05");

 $datediff = $date - $current;
 $difference = floor($datediff/(60*60*24));
 if($difference==0)
 {
    echo 'today';
 }
 else if($difference > 1)
 {
    echo 'Future Date';
 }
 else if($difference > 0)
 {
    echo 'tomorrow';
 }
 else if($difference < -1)
 {
    echo 'Long Back';
 }
 else
 {
    echo 'yesterday';
 }  
?>

To align some elements (headerElement) in the center and the last element to the right (headerEnd).

.headerElement {
    margin-right: 5%;
    margin-left: 5%;
}
.headerEnd{
    margin-left: auto;
}

You can also use PostCSS and the custom selectors plugin

@custom-selector :--headings h1, h2, h3, h4, h5, h6;

article :--headings {
  margin-top: 0;
}

Output:

article h1,
article h2,
article h3,
article h4,
article h5,
article h6 {
  margin-top: 0;
}

You can change the name of the column, therefore instead of "COUNT(*)" you would have something meaningful. You will have to update your "RowCount.sql" script for that.

For example:

SQL> select count(*) as RecordCountFromTableOne from TableOne;

Will be displayed as:

RecordCountFromTableOne
-----------------------
           0

If you want to have space in the title, you need to enclose it in double quotes

SQL> select count(*) as "Record Count From Table One" from TableOne;

Will be displayed as:

Record Count From Table One
---------------------------
            0

Easy and reusable ItemDecoration

Static headers can easily be added with an ItemDecoration and without any further changes.

// add the decoration. done.
HeaderDecoration headerDecoration = new HeaderDecoration(/* init */);
recyclerView.addItemDecoration(headerDecoration);

The decoration is also reusable since there is no need to modify the adapter or the RecyclerView at all.

The sample code provided below will require a view to add to the top which can just be inflated like everything else. It can look like this:

Why static?

If you just have to display text and images this solution is for you—there is no possibility for user interaction like buttons or view pagers, since it will just be drawn to top of your list.

Empty list handling

If there is no view to decorate, the decoration will not be drawn. You will still have to handle an empty list yourself. (One possible workaround would be to add a dummy item to the adapter.)

The code

You can find the full source code here on GitHub including a Builder to help with the initialization of the decorator, or just use the code below and supply your own values to the constructor.

Please be sure to set a correct layout_height for your view. e.g. match_parent might not work properly.

public class HeaderDecoration extends RecyclerView.ItemDecoration {

    private final View mView;
    private final boolean mHorizontal;
    private final float mParallax;
    private final float mShadowSize;
    private final int mColumns;
    private final Paint mShadowPaint;

    public HeaderDecoration(View view, boolean scrollsHorizontally, float parallax, float shadowSize, int columns) {
        mView = view;
        mHorizontal = scrollsHorizontally;
        mParallax = parallax;
        mShadowSize = shadowSize;
        mColumns = columns;

        if (mShadowSize > 0) {
            mShadowPaint = new Paint();
            mShadowPaint.setShader(mHorizontal ?
                    new LinearGradient(mShadowSize, 0, 0, 0,
                            new int[]{Color.argb(55, 0, 0, 0), Color.argb(55, 0, 0, 0), Color.argb(3, 0, 0, 0)},
                            new float[]{0f, .5f, 1f},
                            Shader.TileMode.CLAMP) :
                    new LinearGradient(0, mShadowSize, 0, 0,
                            new int[]{Color.argb(55, 0, 0, 0), Color.argb(55, 0, 0, 0), Color.argb(3, 0, 0, 0)},
                            new float[]{0f, .5f, 1f},
                            Shader.TileMode.CLAMP));
        } else {
            mShadowPaint = null;
        }
    }

            }
        } else {
            outRect.setEmpty();
        }
    }
}

Please note: The GitHub project is my personal playground. It is not thorougly tested, which is why there is no library yet.

What does it do?

An ItemDecoration is additional drawing to an item of a list. In this case, a decoration is drawn to the top of the first item.

The view gets measured and laid out, then it is drawn to the top of the first item. If a parallax effect is added it will also be clipped to the correct bounds.

Use iframe instead:

Do you specify a user name and password to log on? What exactly is your complete command line?

If you're running on your own box, you can either specify a username/password, or use the -E parameter to log on with your Windows credentials (if those are permitted in your SQL server installation).

Marc

It's a little unclear whether you're asking for opinions, eg. "it's common to do xxx" or an actual rule, so I'm going to lean in the direction of rules.

The examples you cite seem based upon the examples in the spec for the nav element. Remember that the spec keeps getting tweaked and the rules are sometimes convoluted, so I'd venture many people might tend to just do what's given rather than interpret. You're showing two separate examples with different behavior, so there's only so much you can read into it. Do either of those sites also have the opposing sub/nav situation, and if so how do they handle it?

Most importantly, though, there's nothing in the spec saying either is the way to do it. One of the goals with HTML5 was to be very clear[this for comparison] about semantics, requirements, etc. so the omission is worth noting. As far as I can see, the examples are independent of each other and equally valid within their own context of layout requirements, etc.

Having the nav's source position be conditional is kind of silly(another red flag). Just pick a method and go with it.

In your binding configuration, there are four timeout values you can tweak:

<bindings>
  <basicHttpBinding>
    <binding name="IncreasedTimeout"
             sendTimeout="00:25:00">
    </binding>
  </basicHttpBinding>

The most important is the sendTimeout, which says how long the client will wait for a response from your WCF service. You can specify hours:minutes:seconds in your settings - in my sample, I set the timeout to 25 minutes.

The openTimeout as the name implies is the amount of time you're willing to wait when you open the connection to your WCF service. Similarly, the closeTimeout is the amount of time when you close the connection (dispose the client proxy) that you'll wait before an exception is thrown.

The receiveTimeout is a bit like a mirror for the sendTimeout - while the send timeout is the amount of time you'll wait for a response from the server, the receiveTimeout is the amount of time you'll give you client to receive and process the response from the server.

In case you're send back and forth "normal" messages, both can be pretty short - especially the receiveTimeout, since receiving a SOAP message, decrypting, checking and deserializing it should take almost no time. The story is different with streaming - in that case, you might need more time on the client to actually complete the "download" of the stream you get back from the server.

There's also openTimeout, receiveTimeout, and closeTimeout. The MSDN docs on binding gives you more information on what these are for.

To get a serious grip on all the intricasies of WCF, I would strongly recommend you purchase the "Learning WCF" book by Michele Leroux Bustamante:

Learning WCF http://ecx.images-amazon.com/images/I/51GNuqUJq%2BL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg

and you also spend some time watching her 15-part "WCF Top to Bottom" screencast series - highly recommended!

For more advanced topics I recommend that you check out Juwal Lowy's Programming WCF Services book.

Programming WCF http://ecx.images-amazon.com/images/I/41odWcLoGAL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg

I had to extract numbers first from a list of float strings:

   df4['sscore'] = df4['simscore'].str.findall('\d+\.\d+')

then each convert to a float:

   ad=[]
   for z in range(len(df4)):
      ad.append([float(i) for i in df4['sscore'][z]])

in the end assign all floats to a dataframe as float64:

   df4['fscore'] = np.array(ad,dtype=float)

When creating the TABLE under B2BOWNER, be sure to prefix the PL/SQL function with the Schema name; i.e. B2BOWNER.F_SSC_Page_Map_Insert.

I did not realize this until the DBAs pointed it out. I could have created the table under my root USER/SCHEMA and the PL/SQL function would have worked fine.

Alternative: Install adb the easy way

If you don't want to have to worry about your path or updating adb manually, you can use homebrew instead.

brew cask install android-platform-tools

cbindX from the package gdata combines multiple columns of differing column and row lengths. Check out the page here:

http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/gdata/html/cbindX.html

It takes multiple comma separated matrices and data.frames as input :) You just need to

install.packages("gdata", dependencies=TRUE)

and then

library(gdata)
concat_data <- cbindX(df1, df2, df3) # or cbindX(matrix1, matrix2, matrix3, matrix4)

open a terminal and run this command xhost +. This commands needs to be run every time you restart your machine. If everything works fine may be you can add this to startup commands

Also make sure in your /etc/environment file there is a line

export DISPLAY=:0.0 

And then, run your tests to see if your issue is resolved.

All please note the comment from sardathrion below before using this.

1. Go to Sql Server Management Studio >
2. Object Explorer >
3. Databases >
4. Choose and expand your Database.
5. Under your database right click on "Database Diagrams" and select "New Database Diagram".
6. It will a open a new window. Choose tables to include in ER-Diagram (to select multiple tables press "ctrl" or "shift" button and select tables).
7. Click add.
8. Wait for it to complete. Done!

You can save generated diagram for future use.

Well I think the forloop you've provided in the question is about as good as it gets, but I want to point out that unused variables that have to be assigned can be assigned to the variable named _, a convention for "discarding" the value assigned. Though the _ reference will hold the value you gave it, code linters and other developers will understand you aren't using that reference. So here's an example:

for _ in range(2):
    print('Hello')

tips

in package.json:

"scripts": {
  "start": "set NODE_ENV=dev && node app.js"
 }

in app.js:

console.log(process.env.NODE_ENV) // dev
console.log(process.env.NODE_ENV === 'dev') // false
console.log(process.env.NODE_ENV.length) // 4 (including a space at the end) 

so, this may better:

"start": "set NODE_ENV=dev&& node app.js"

or

console.log(process.env.NODE_ENV.trim() === 'dev') // true

If you use old version of MySQL you can always use \P combined with some nice piece of awk code. Interesting example here

Isn't it exactly what you need?

Pass the decode pattern to ParseExact

Dim d as string = "201210120956"
Dim dt = DateTime.ParseExact(d, "yyyyMMddhhmm", Nothing)

ParseExact is available only from Net FrameWork 2.0.
If you are still on 1.1 you could use Parse, but you need to provide the IFormatProvider adequate to your string

If one need to use the sp_executesql with OUTPUT variables:

EXEC sp_executesql @sql
                  ,N'@p0 INT'
                  ,N'@p1 INT OUTPUT'
                  ,N'@p2 VARCHAR(12) OUTPUT' 
                  ,@p0
                  ,@p1 OUTPUT
                  ,@p2 OUTPUT;

Yep, you'll want to do something like this:

echo -n "Enter Fullname: " 
read fullname

Another option would be to have them supply this information on the command line. Getopts is your best bet there.

Using getopts in bash shell script to get long and short command line options

I find it useful when including or requiring _dbconnection.php_ and _functions.php in files that are actually processed, rather than including in the header. Which is included in itself.

So if your header and footer is included, simply include all your functional files before the header is included.

Here is snippet that allowed me to log out programmatically from facebook. Let me know if you see anything that I might need to improve.

private void logout(){
    // clear any user information
    mApp.clearUserPrefs();
    // find the active session which can only be facebook in my app
    Session session = Session.getActiveSession();
    // run the closeAndClearTokenInformation which does the following
    // DOCS : Closes the local in-memory Session object and clears any persistent 
    // cache related to the Session.
    session.closeAndClearTokenInformation();
    // return the user to the login screen
    startActivity(new Intent(getApplicationContext(), LoginActivity.class));
    // make sure the user can not access the page after he/she is logged out
    // clear the activity stack
    finish();
}

Use the following Code:-

../css/main.css

Note: The "../" is shorthand for "The containing directory", or "Up one directory".

If you don't know the previous folder this will be very helpful..

For higher version of phpunit such as 6.4 You must use the namespace PHPUnit\Framework\TestCase

use TestCase instead PHPUnit_Framework_TestCase

// use the following namespace
use PHPUnit\Framework\TestCase;

// extend using TestCase instead PHPUnit_Framework_TestCase
class SampleTest extends TestCase {

}

As Oscar Wilde said

Consistency is the last refuge of the unimaginative.

R is more of an evolved rather than designed language, so these things happen. names() and colnames() work on a data.frame but names() does not work on a matrix:

R> DF <- data.frame(foo=1:3, bar=LETTERS[1:3])
R> names(DF)
[1] "foo" "bar"
R> colnames(DF)
[1] "foo" "bar"
R> M <- matrix(1:9, ncol=3, dimnames=list(1:3, c("alpha","beta","gamma")))
R> names(M)
NULL
R> colnames(M)
[1] "alpha" "beta"  "gamma"
R> 

This is not a solution, it's just a workaround.

1. Click on your visual studio project (top level) in the solution explorer and go to the properties window.

2. Change SSL Enabled to true. You will now see another port number as 'SSL URL' in the properties window.

3. Now, when you run your application (or view in browser), you have to manually change the port number to the SSL port number in the address bar.

Now it works fine as a SSL link

Another way is with: overflow-y:hidden on the parent with padding.

#wrap {
    overflow-y: hidden;
    padding: 0 10px;
}
#wrap > div {
    width: 100px;
    height: 100px;
    box-shadow: 0 0 20px -5px red;
}

const arrString = ["1","2","3","4","5"];
const arrInteger = arrString.map(x => Number.parseInt(x, 10));

Above one should be simple enough,

One tricky part is when you try to use point free function for map as below

const arrString = ["1","2","3","4","5"];
const arrInteger = arrString.map(Number.parseInt);

In this case, result will be [1, NaN, NaN, NaN, NaN] since function argument signature for map and parseInt differs

map expects - (value, index, array) where as parseInt expects - (value, radix)

Your html is completely wrong for starters, there should not be a div within your head section, nor after your body section. I suggest you look into correct html first before starting to work with favicons etc.

Not directly the requested answer, but maybe the root-cause of the question:

You can also prevent commands from even getting into the history, by prefixing them with a space character:

# This command will be in the history
echo Hello world

# This will not
 echo Hello world

You can also use the unix style time to calculate:

$newtime = time() + ($hours * 60 * 60); // hours; 60 mins; 60secs
echo 'Now:       '. date('Y-m-d') ."\n";
echo 'Next Week: '. date('Y-m-d', $newtime) ."\n";

your log files shows it is stopping on error "0x8004C000"

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

Edit

Further explanation: How does Python compare string and int?

Another solution:

public class CountryInfoResponse {
  private List<Object> geonames;
}

Usage of a generic Object-List solved my problem, as there were other Datatypes like Boolean too.

simply add as many properties as you need to the data object.

 $.ajax({
                    type: "POST",
                    url: "popup.aspx/GetJewellerAssets",
                    contentType: "application/json; charset=utf-8",
                    data: {jewellerId: filter , foo: "bar", other: "otherValue"},
                    dataType: "json",
                    success: AjaxSucceeded,
                    error: AjaxFailed
                });

You can use jquery numeric for numbers.
The current version does allow what you're looking for but someone has changed the code a little bit and it works:

HTML

<input class="numeric" type="text" />

Javascript

$(".numeric").numeric({ decimal : ".",  negative : false, scale: 3 });

This is the whole source.
And I've prepared this fiddle so you can see how it works.

A class that will play a WAV file, blocking until the sound has finished playing:

class Sound implements Playable {

    private final Path wavPath;
    private final CyclicBarrier barrier = new CyclicBarrier(2);

    Sound(final Path wavPath) {

        this.wavPath = wavPath;
    }

    @Override
    public void play() throws LineUnavailableException, IOException, UnsupportedAudioFileException {

        try (final AudioInputStream audioIn = AudioSystem.getAudioInputStream(wavPath.toFile());
             final Clip clip = AudioSystem.getClip()) {

            listenForEndOf(clip);
            clip.open(audioIn);
            clip.start();
            waitForSoundEnd();
        }
    }

    private void listenForEndOf(final Clip clip) {

        clip.addLineListener(event -> {
            if (event.getType() == LineEvent.Type.STOP) waitOnBarrier();
        });
    }

    private void waitOnBarrier() {

        try {

            barrier.await();
        } catch (final InterruptedException ignored) {
        } catch (final BrokenBarrierException e) {

            throw new RuntimeException(e);
        }
    }

    private void waitForSoundEnd() {

        waitOnBarrier();
    }
}

I was facing the same issue, I was adding

"types": ["node"]

to tsconfig.json of root folder.

There was one more tsconfig.app.json under src folder and I got solved this by adding

"types": ["node"]

to tsconfig.app.json file under compilerOptions

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "types": ["node"]  ----------------------< added node to the array
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

Perhaps this is what you are looking for:

import os
os.chdir(default_path)

NPM commands to update or fix vulnerabilities in some dependency manifest files

• Use below command to check outdated or vulnerabilities in your node modules.

  npm audit

• If any vulnerabilities found, use below command to fix all issues.

  npm audit fix

• If it doesn't work for you then try

  npm audit fix -f, this command will almost fix all vulnerabilities. Some dependencies or devDependencies are locked in package-lock.json file, so we use -f flag to force update them.

• If you don't want to use force audit fix then you can manually fix your dependencies versions by changing them in package-lock.json and package.json file. Then run

npm update && npm upgrade

SQL Server 2012 above, I prefer use format() function, more simplify.

SELECT format(date,'MM.yyyy') AS Mjesec, SUM(marketingExpense) AS SumaMarketing, SUM(revenue) AS SumaZarada 
FROM [Order]
WHERE (idCustomer = 1) AND (date BETWEEN '2001-11-3' AND '2011-11-3')
GROUP BY format(date,'MM.yyyy')

Without seeing your full code, this is impossible to answer with any certainty. The error usually occurs when you are trying to unload a control rather than the form.

Make sure that you don't have the "me" in brackets.

Also if you can post the full code for the userform it would help massively.

Sven has shown how to use the class gaussian_kde from Scipy, but you will notice that it doesn't look quite like what you generated with R. This is because gaussian_kde tries to infer the bandwidth automatically. You can play with the bandwidth in a way by changing the function covariance_factor of the gaussian_kde class. First, here is what you get without changing that function:

However, if I use the following code:

import matplotlib.pyplot as plt
import numpy as np
from scipy.stats import gaussian_kde
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = gaussian_kde(data)
xs = np.linspace(0,8,200)
density.covariance_factor = lambda : .25
density._compute_covariance()
plt.plot(xs,density(xs))
plt.show()

I get

which is pretty close to what you are getting from R. What have I done? gaussian_kde uses a changable function, covariance_factor to calculate its bandwidth. Before changing the function, the value returned by covariance_factor for this data was about .5. Lowering this lowered the bandwidth. I had to call _compute_covariance after changing that function so that all of the factors would be calculated correctly. It isn't an exact correspondence with the bw parameter from R, but hopefully it helps you get in the right direction.

Brief answer to your question: No. You shouldn't call ConfigureAwait(false) at the application level like that.

TL;DR version of the long answer: If you are writing a library where you don't know your consumer and don't need a synchronization context (which you shouldn't in a library I believe), you should always use ConfigureAwait(false). Otherwise, the consumers of your library may face deadlocks by consuming your asynchronous methods in a blocking fashion. This depends on the situation.

Here is a bit more detailed explanation on the importance of ConfigureAwait method (a quote from my blog post):

When you are awaiting on a method with await keyword, compiler generates bunch of code in behalf of you. One of the purposes of this action is to handle synchronization with the UI (or main) thread. The key component of this feature is the SynchronizationContext.Current which gets the synchronization context for the current thread. SynchronizationContext.Current is populated depending on the environment you are in. The GetAwaiter method of Task looks up for SynchronizationContext.Current. If current synchronization context is not null, the continuation that gets passed to that awaiter will get posted back to that synchronization context.

When consuming a method, which uses the new asynchronous language features, in a blocking fashion, you will end up with a deadlock if you have an available SynchronizationContext. When you are consuming such methods in a blocking fashion (waiting on the Task with Wait method or taking the result directly from the Result property of the Task), you will block the main thread at the same time. When eventually the Task completes inside that method in the threadpool, it is going to invoke the continuation to post back to the main thread because SynchronizationContext.Current is available and captured. But there is a problem here: the UI thread is blocked and you have a deadlock!

Also, here are two great articles for you which are exactly for your question:

• The Perfect Recipe to Shoot Yourself in The Foot - Ending up with a Deadlock Using the C# 5.0 Asynchronous Language Features
• Asynchronous .NET Client Libraries for Your HTTP API and Awareness of async/await's Bad Effects

Finally, there is a great short video from Lucian Wischik exactly on this topic: Async library methods should consider using Task.ConfigureAwait(false).

Hope this helps.

Use below code to generate files on fly..

<? //Generate text file on the fly

   header("Content-type: text/plain");
   header("Content-Disposition: attachment; filename=savethis.txt");

   // do your Db stuff here to get the content into $content
   print "This is some text...\n";
   print $content;
 ?>

First loop

$v = $a[0];
$v = $a[1];
$v = $a[2];
$v = $a[3];

Yes! Current $v = $a[3] position.

Second loop

$a[3] = $v = $a[0], echo $v; // same as $a[3] and $a[0] == 'zero'
$a[3] = $v = $a[1], echo $v; // same as $a[3] and $a[1] == 'one'
$a[3] = $v = $a[2], echo $v; // same as $a[3] and $a[2] == 'two'
$a[3] = $v = $a[3], echo $v; // same as $a[3] and $a[3] == 'two'

because $a[3] is assigned by before processing.

Use get_text(), it returns all the text in a document or beneath a tag, as a single Unicode string.

For instance, remove all different script tags from the following text:

<td><a href="http://www.irit.fr/SC">Signal et Communication</a>
<br/><a href="http://www.irit.fr/IRT">Ingénierie Réseaux et Télécommunications</a>
</td>

The expected result is:

Signal et Communication
Ingénierie Réseaux et Télécommunications

Here is the source code:

#!/usr/bin/env python3
from bs4 import BeautifulSoup

text = '''
<td><a href="http://www.irit.fr/SC">Signal et Communication</a>
<br/><a href="http://www.irit.fr/IRT">Ingénierie Réseaux et Télécommunications</a>
</td>
'''
soup = BeautifulSoup(text)

print(soup.get_text())

Since Spring 3.1 the id attribute is an xsd:string and permits the same range of characters as the name attribute.

The only difference between an id and a name is that a name can contain multiple aliases separated by a comma, semicolon or whitespace, whereas an id must be a single value.

From the Spring 3.2 documentation:

In XML-based configuration metadata, you use the id and/or name attributes to specify the bean identifier(s). The id attribute allows you to specify exactly one id. Conventionally these names are alphanumeric ('myBean', 'fooService', etc), but may special characters as well. If you want to introduce other aliases to the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was typed as an xsd:ID, which constrained possible characters. As of 3.1, it is now xsd:string. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers.

If the goal is to be able to push to a GitHub repo whenever you want to, then in Windows under C:\Users\tiago\.ssh where the keys are stored (at least in my case), create a file named config and add the following in it

Host github.com
    HostName github.com
    User your_user_name
    IdentityFile ~/.ssh/your_file_name

Then simply open Git Bash and you'll be able to push without having to manually start the ssh-agent and adding the key.

First install openpyxl:

pip install openpyxl

Then:

from openpyxl import Workbook

wb = Workbook()
ws = wb.active
with open('test.csv', 'r') as f:
    for row in csv.reader(f):
        ws.append(row)
wb.save('name.xlsx')

Mono Develop is what you want, if you have used visual studio you should find it simple enough to get started.

If I recall correctly you should be able to install with sudo apt-get install monodevelop

There is the question whether we want to differentiate between cases:

1. "phone" : "" = the value is empty

2. "phone" : null = the value for "phone" was not set yet

If we want differentiate I would use null for this. Otherwise we would need to add a new field like "isAssigned" or so. This is an old Database issue.

If you are in a network of users, then the username will be different:

Environment.UserName

Will Display format : 'Username', rather than

System.Security.Principal.WindowsIdentity.GetCurrent().Name

Will Display format : 'NetworkName\Username'

Choose the format you want.

    printf("but now I will sleep 15 second, then exit");
    sleep(15);
}

Start server side, then start client side.

server side may output:

accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0

client side may output:

You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer get full, but you still send data, so you may get Resource temporarily unavailable error.

For MacOS users, if you forget your root password, @thusharaK's answer(https://stackoverflow.com/a/28601069/5628856) is good, but there are a little more tricks:

If you are using system preference to start mysql serverside, simply

sudo mysqld_safe --skip-grant-tables

might not work for you.

You have to make sure the command line arguments is same with system start config.

The following command works for me:

/usr/local/mysql/bin/mysqld --user=_mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --log-error=/usr/local/mysql/data/mysqld.local.err --pid-file=/usr/local/mysql/data/mysqld.local.pid --keyring-file-data=/usr/local/mysql/keyring/keyring --early-plugin-load=keyring_file=keyring_file.so --skip-grant-tables

You can use

ps aux | grep mysql

to check your own.

To prevent "Div parent" use margin of "div child":
In parent use these css:

• Float
• Padding
• Border
• Overflow

On top of what @wisekiddo said, you can also modify your build settings in the project.pbxproj file by setting the Swift 3 @obj Inference to default like SWIFT_SWIFT3_OBJC_INFERENCE = Default; for your build flavors (i.e. debug and release), especially if you're coming from some other environment besides Xcode

Yes but it is not quite that easy. Create a third array that is the size of the two arrays combined and loop through each original array and move the items over. Also look into System.arraycopy().

After googling I write a simple Exception handing based on MVC Action Filter:

public class HandleExceptionAttribute : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        if (filterContext.HttpContext.Request.IsAjaxRequest() && filterContext.Exception != null)
        {
            filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
            filterContext.Result = new JsonResult
            {
                JsonRequestBehavior = JsonRequestBehavior.AllowGet,
                Data = new
                {
                    filterContext.Exception.Message,
                    filterContext.Exception.StackTrace
                }
            };
            filterContext.ExceptionHandled = true;
        }
        else
        {
            base.OnException(filterContext);
        }
    }
}

and write in global.ascx:

 public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 {
      filters.Add(new HandleExceptionAttribute());
 }

and then write this script on the layout or Master page:

<script type="text/javascript">
      $(document).ajaxError(function (e, jqxhr, settings, exception) {
                       e.stopPropagation();
                       if (jqxhr != null)
                           alert(jqxhr.responseText);
                     });
</script>

Finally you should turn on custom error. and then enjoy it :)

Add programatically noborder class to specific row to hide it

<style>
     .noborder
      {
        border:none;
      }
    </style>

<table>

    <tr>
       <th>heading1</th>
       <th>heading2</th>
    </tr>


    <tr>
       <td>content1</td>
       <td>content2</td>
    </tr>
    /*no border for this row */
    <tr class="noborder">
       <td>content1</td>
       <td>content2</td>
    </tr>

</table>
