As others have pointed out

• both are equivalent apart from default visibility
• there may be reasons to be forced to use the one or the other for whatever reason

There's a clear recommendation about when to use which from Stroustrup/Sutter:

Use class if the class has an invariant; use struct if the data members can vary independently

However, keep in mind that it is not wise to forward declare sth. as a class (class X;) and define it as struct (struct X { ... }). It may work on some linkers (e.g., g++) and may fail on others (e.g., MSVC), so you will find yourself in developer hell.

best explanation of Cohesion comes from Uncle Bob's Clean Code:

Classes should have a small number of instance variables. Each of the methods of a class should manipulate one or more of those variables. In general the more variables a method manipulates the more cohesive that method is to its class. A class in which each variable is used by each method is maximally cohesive.

In general it is neither advisable nor possible to create such maximally cohesive classes; on the other hand, we would like cohesion to be high. When cohesion is high, it means that the methods and variables of the class are co-dependent and hang together as a logical whole.

The strategy of keeping functions small and keeping parameter lists short can sometimes lead to a proliferation of instance variables that are used by a subset of methods. When this happens, it almost always means that there is at least one other class trying to get out of the larger class. You should try to separate the variables and methods into two or more classes such that the new classes are more cohesive.

Abstraction - It is the process of identifying the essential characteristics of an object without including the irrelevant and tedious details.

Encapsulation - It is the process of enclosing data and functions manipulating this data into a single unit.

Abstraction and Encapsulation are related but complementary concepts.

1. Abstraction is the process. Encapsulation is the mechanism by which Abstraction is implemented.

2. Abstraction focuses on the observable behavior of an object. Encapsulation focuses upon the implementation that give rise to this behavior.

Information Hiding - It is the process of hiding the implementation details of an object. It is a result of Encapsulation.

Short and clear answer

• High cohesion: Elements within one class/module should functionally belong together and do one particular thing.
• Loose coupling: Among different classes/modules should be minimal dependency.

A 404 return code actually means 'resource not found', and applies to any entity for which a request was made but not satisfied. So it works equally-well for pages, subsections of pages, and any item that exists on the page which has a specific request to be rendered.

So 404 is the right code to use in this scenario. Note that it doesn't apply to 'server not found', which is a different situation in which a request was issued but not answered at all, as opposed to answered but without the resource requested.

If you want to see only fatal runtime errors:

php_value display_errors on
php_value error_reporting 4

You could reference the variable in an assertion and then build with -fsanitize=address:

void foo (int32_t& i) {
    // Assertion will trigger address sanitizer if not initialized:
    assert(static_cast<int64_t>(i) != INT64_MAX);
}

This will cause the program to reliably crash with a stack trace (as opposed to undefined behavior).

Here's your method:

public static Calendar toCalendar(Date date){ 
  Calendar cal = Calendar.getInstance();
  cal.setTime(date);
  return cal;
}

Everything else you are doing is both wrong and unnecessary.

BTW, Java Naming conventions suggest that method names start with a lower case letter, so it should be: dateToCalendar or toCalendar (as shown).

OK, let's milk your code, shall we?

DateFormat formatter = new SimpleDateFormat("yyyyMMdd");
date = (Date)formatter.parse(date.toString()); 

DateFormat is used to convert Strings to Dates (parse()) or Dates to Strings (format()). You are using it to parse the String representation of a Date back to a Date. This can't be right, can it?

Make sure to check the schema at the database level directly. I've gotten burned by this before, where, for example, a migration was initially written to create a :datetime column, and I ran it locally, then tweaked the migration to a :date before actually deploying. Thus everyone's database looks good except for mine, and the bugs are subtle.

I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really 'fields'. You'll know if it is a field if the caption's background turns grey when you put your cursor on them (or is permanently displayed grey).

Captions are fields - Unfortunately fields (like caption fields) are only updated on specific actions, like opening of the document, printing, switching from print view to normal view, etc. The easiest way to force updating of all (caption) fields when you want it is by doing the following:

1. Select all text in your document (easiest way is to press ctrl-a)
2. Press F9, this command tells Word to update all fields in the selection.

Captions are normal text - If the caption number is not a field, I am afraid you'll have to edit the text manually.

Check the image above I hope it will help someone.

Brad Wilson has a couple great articles on unobtrusive validation and unobtrusive ajax.
It is also shown very nicely in this Pluralsight video in the section on " AJAX and JavaScript".

Basically, it is simply Javascript validation that doesn't pollute your source code with its own validation code. This is done by making use of data- attributes in HTML.

CONVERT(datetime, '24.04.2012', 104)

Should do the trick. See here for more info: CAST and CONVERT (Transact-SQL)

Unfortunately, that's not supported in the Django template language. There are a couple of suggestions, but they seem a little complex. I would just put a variable in the context:

...
render_to_response('foo.html', {..., 'range': range(10), ...}, ...)
...

and in the template:

{% for i in range %}
     ...
{% endfor %}

Is Powershell an option?

rasdial connectionname [username [password | \]] [/domain:domain*] [/phone:phonenumber] [/callback:callbacknumber] [/phonebook:phonebookpath] [/prefixsuffix**]

You can manage your VPN connections with the powershell commands above, and simply use the connection name to connect via rasdial.

The results of Get-VpnConnection can be a little verbose. This can be simplified with a simple Select-Object filter:

Get-VpnConnection | Select-Object -Property Name

I vote for:

await Promise.all([someCall(), anotherCall()]);

Be aware of the moment you call functions, it may cause unexpected result:

// Supposing anotherCall() will trigger a request to create a new User

if (callFirst) {
  await someCall();
} else {
  await Promise.all([someCall(), anotherCall()]); // --> create new User here
}

But following always triggers request to create new User

// Supposing anotherCall() will trigger a request to create a new User

const someResult = someCall();
const anotherResult = anotherCall(); // ->> This always creates new User

if (callFirst) {
  await someCall();
} else {
  const finalResult = [await someResult, await anotherResult]
}

Imagine you have have a Book model and a Page model,

1:N means:
One book can have **many** pages. One page can only be in **one** book.


N:N means:
One book can have **many** pages. And one page can be in **many** books.

Something like this might work:

$("body").attr("class", "about");

It uses jQuery's attr() to add the class 'about' to the body.

Echo inside an HTML element with class and style the element:

echo "<span class='name'>" . $ip['cityName'] . "</span>";

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

This block of code makes a path of your app directory in string type

The answer to "Any idea for getting all attributes at once?" question is just to call function with only product id:

$array=get_post_meta($product->id);

key is optional, see http://codex.wordpress.org/Function_Reference/get_post_meta

I´ve used this:

String currentLanguage = Locale.getDefault().getDisplayLanguage();
if (currentLanguage.toLowerCase().contains("en")) {
   //do something
}

Node.js supports circular dependencies.
Making use of circular dependencies instead of require('./routes')(app) cleans up a lot of code and makes each module less interdependent on its loading file:

var app = module.exports = express(); //now app.js can be required to bring app into any file

//some app/middleware setup, etc, including 
app.use(app.router);

require('./routes'); //module.exports must be defined before this line

var app = require('../app');

app.get('/', function(req, res, next) {
  res.render('index');
});

//require in some other route files...each of which requires app independently
require('./user');
require('./blog');

Example from their new generator:
Writing the route:
https://github.com/expressjs/generator/blob/master/templates/js/routes/index.js
Adding/namespacing it to the app: https://github.com/expressjs/generator/blob/master/templates/js/app.js#L24

There are still usecases for accessing app from other resources, so circular dependencies are still a valid solution.

First, we must make a distinction between layers and tiers. Layers are the way to logically break code into components and tiers are the physical nodes to place the components on. This question explains it better: What's the difference between "Layers" and "Tiers"?

A two layer architecture is usually just a presentation layer and data store layer. These can be on 1 tier (1 machine) or 2 tiers (2 machines) to achieve better performance by distributing the work load.

A three layer architecture usually puts something between the presentation and data store layers such as a business logic layer or service layer. Again, you can put this into 1,2, or 3 tiers depending on how much money you have for hardware and how much load you expect.

Putting multiple machines in a tier will help with the robustness of the system by providing redundancy.

Below is a good example of a layered architecture:

_{(source: microsoft.com)}

A good reference for all of this can be found here on MSDN: http://msdn.microsoft.com/en-us/library/ms978678.aspx

You can pass all your optional arguments in an object as the first argument. The second argument is your callback. Now you can accept as many arguments as you want in your first argument object, and make it optional like so:

function my_func(op, cb) {
    var options = (typeof arguments[0] !== "function")? arguments[0] : {},
        callback = (typeof arguments[0] !== "function")? arguments[1] : arguments[0];

    console.log(options);
    console.log(callback);
}

If you call it without passing the options argument, it will default to an empty object:

my_func(function () {});
=> options: {}
=> callback: function() {}

If you call it with the options argument you get all your params:

my_func({param1: 'param1', param2: 'param2'}, function () {});
=> options: {param1: "param1", param2: "param2"}
=> callback: function() {}

This could obviously be tweaked to work with more arguments than two, but it get's more confusing. If you can just use an object as your first argument then you can pass an unlimited amount of arguments using that object. If you absolutely need more optional arguments (e.g. my_func(arg1, arg2, arg3, ..., arg10, fn)), then I would suggest using a library like ArgueJS. I have not personally used it, but it looks promising.

You can access sequence elements with arr.0 arr.1 and so on. See The Django template system chapter of the django book for more information.

As far as caching the response in service is concerned , here's another version that seems more straight forward than what I've seen so far:

App.factory('dataStorage', function($http) {
     var dataStorage;//storage for cache

     return (function() {
         // if dataStorage exists returned cached version
        return dataStorage = dataStorage || $http({
      url: 'your.json',
      method: 'GET',
      cache: true
    }).then(function (response) {

              console.log('if storage don\'t exist : ' + response);

              return response;
            });

    })();

});

this service will return either the cached data or $http.get;

 dataStorage.then(function(data) {
     $scope.data = data;
 },function(e){
    console.log('err: ' + e);
 });

You could either use a negative look-ahead or look-behind:

^(?!.*?bar).*
^(.(?<!bar))*?$

Or use just basics:

^(?:[^b]+|b(?:$|[^a]|a(?:$|[^r])))*$

These all match anything that does not contain bar.

You can use a temporary variable:

boolean outerBreak = false;
for (Type type : types) {
   if(outerBreak) break;
    for (Type t : types2) {
         if (some condition) {
             // Do something and break...
             outerBreak = true;
             break; // Breaks out of the inner loop
         }
    }
}

Depending on your function, you can also exit/return from the inner loop:

for (Type type : types) {
    for (Type t : types2) {
         if (some condition) {
             // Do something and break...
             return;
         }
    }
}

Another method could be to split the string by ":" and then pop off the end. var newString = string.split(":").pop();

You could include in your data hash a key called: _method with value 'delete'.

For example:

data = { id: 1, _method: 'delete' };
url = '/products'
request = $.post(url, data);
request.done(function(res){
  alert('Yupi Yei. Your product has been deleted')
});

This will also apply for

You can pass in the element to the controller, just like the scope:

function someControllerFunc($scope, $element){

}

you don't need to specify a "SimpleDateFormat", it's simple: You must do specify the constant "DatatypeConstants.FIELD_UNDEFINED" where you don't want to show

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(new Date());
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendarDate(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH)+1, cal.get(Calendar.DAY_OF_MONTH), DatatypeConstants.FIELD_UNDEFINED);

Something simple like this can be done using subqueries in the select clause:

select ((select sum(hours) from resource) +
        (select sum(hours) from projects-time)
       ) as totalHours

For such a simple query as this, such a subselect is reasonable.

In some databases, you might have to add from dual for the query to compile.

If you want to output each individually:

select (select sum(hours) from resource) as ResourceHours,
       (select sum(hours) from projects-time) as ProjectHours

If you want both and the sum, a subquery is handy:

select ResourceHours, ProjectHours, (ResourceHours+ProjecctHours) as TotalHours
from (select (select sum(hours) from resource) as ResourceHours,
             (select sum(hours) from projects-time) as ProjectHours
     ) t

This works in FF, IE9

var x = document.getElementById("country").children[2];
x.setAttribute("selected", "selected");

Following code replaces any nun-numeric character with '', allowing you to count number of such characters with function len.

import re
len(re.sub("[^0-9]", "", my_string))

Alphabetical:

import re
len(re.sub("[^a-zA-Z]", "", my_string))

The .css() function doesn't queue behind running animations, it's instantaneous.

To match the behaviour that you're after, you'd need to do the following:

$(document).ready(function() {
  $("button").mouseover(function() {
    var p = $("p#44.test").css("background-color", "yellow");
    p.hide(1500).show(1500);
    p.queue(function() {
      p.css("background-color", "red");
    });
  });
});

The .queue() function waits for running animations to run out and then fires whatever's in the supplied function.

Source: http://rubydoc.info/gems/extlib/0.9.15/String#camel_case-instance_method

For learning purpose:

class String
  def camel_case
    return self if self !~ /_/ && self =~ /[A-Z]+.*/
    split('_').map{|e| e.capitalize}.join
  end
end

"foo_bar".camel_case          #=> "FooBar"

And for the lowerCase variant:

class String
  def camel_case_lower
    self.split('_').inject([]){ |buffer,e| buffer.push(buffer.empty? ? e : e.capitalize) }.join
  end
end

"foo_bar".camel_case_lower          #=> "fooBar"

However, if you have indented code, it doesn't work out so well:

    echo "continuation \
    lines"
>continuation     lines

Try with single quotes and concatenating the strings:

    echo 'continuation' \
    'lines'
>continuation lines

Note: the concatenation includes a whitespace.

I have similar problem. I had to logout and login again to shell because I have just installed Docker and following command didn't show in my environment.

export DOCKER_HOST=127.0.0.1:4243 >> ~/.bashrc

Not exactly the same as NUnit's Value (or TestCase) attributes, but MSTest has the DataSource attribute, which allows you to do a similar thing.

You can hook it up to database or XML file - it is not as straightforward as NUnit's feature, but it does the job.

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

I've refactored your code a bit, this should work:

jQuery("#loadActive").click(writeData);

function writeData() {
    jQuery("#chatTickets input:radio").attr('disabled',true);
}

If there are more than two radio buttons on your form, you'll have to modify the selector, for example, you can use the starts with attribute filter to pick out the radios whose ID starts with ticketID:

function writeData() {
    jQuery("#chatTickets input[id^=ticketID]:radio").attr('disabled',true);
}

The best approach here is to remove @ActiveProfiles annotation and do the following:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
    TestPreperationExecutionListener.class
    })
@Transactional
@ContextConfiguration(locations = {
    "classpath:config/test-context.xml" })
public class TestContext {

  @BeforeClass
  public static void setSystemProperty() {
        Properties properties = System.getProperties();
        properties.setProperty("spring.profiles.active", "localtest");
  }

  @AfterClass
  public static void unsetSystemProperty() {
        System.clearProperty("spring.profiles.active");
  }

  @Test
  public void testContext(){

  }
}

And your test-context.xml should have the following:

<context:property-placeholder 
  location="classpath:META-INF/spring/config_${spring.profiles.active}.properties"/>

I found the problem to this... due to a incorrect/failed reference in .rdl to data conns etc. Also found that BIDS wasn't happy about having spaces in some of the project/report filenames... so anyone facing this issue make sure you have no spaces in your naming and check your rdl files, connections, everything for failed/out of date references! Visual Studio seems crap at keeping all of it's references up to date... god forbid you have to rename anything!

For a backward search you should use the following:

for (ListIterator<SomeClass> iterator = list.listIterator(list.size()); iterator.hasPrevious();) {
    SomeClass item = iterator.previous();
    ...
    item.remove(); // For instance.
}

If you want to know a position, use iterator.previousIndex(). It also helps to write an inner loop that compares two positions in the list (iterators are not equal).

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Using DateTime class in PHP7+:

function getMysqlDatetimeFromDate(int $day, int $month, int $year): string
{
 $dt = new DateTime();
 $dt->setDate($year, $month, $day);
 $dt->setTime(0, 0, 0, 0); // set time to midnight

 return $dt->format('Y-m-d H:i:s');
}

Try this:

SELECT
    od.Sku,
    od.mf_item_number,
    od.Qty,
    od.Price,
    s.SupplierId,
    s.SupplierName,
    s.DropShipFees,
    si.Price as cost
FROM
    OrderDetails od
    INNER JOIN Supplier s on s.SupplierId = od.Mfr_ID
    INNER JOIN Group_Master gm on gm.Sku = od.Sku
    INNER JOIN Supplier_Item si on si.SKU = od.Sku and si.SupplierId = s.SupplierID
WHERE
    od.invoiceid = '339740'

This will return multiple rows that are identical except for the cost column. Look at the different cost values that are returned and figure out what is causing the different values. Then ask somebody which cost value they want, and add the criteria to the query that will select that cost.

This one solved my issue which is SELinux setting:

Since version 4.14 of Linux kernel, vfs_read and vfs_write functions are no longer exported for use in modules. Instead, functions exclusively for kernel's file access are provided:

# Read the file from the kernel space.
ssize_t kernel_read(struct file *file, void *buf, size_t count, loff_t *pos);

# Write the file from the kernel space.
ssize_t kernel_write(struct file *file, const void *buf, size_t count,
            loff_t *pos);

Also, filp_open no longer accepts user-space string, so it can be used for kernel access directly (without dance with set_fs).

A couple of code examples in C# using SelectNextControl.

The first moves to the next control when ENTER is pressed.

    private void Control_KeyUp( object sender, KeyEventArgs e )
    {
        if( (e.KeyCode == Keys.Enter) || (e.KeyCode == Keys.Return) )
        {
            this.SelectNextControl( (Control)sender, true, true, true, true );
        }
    }

The second uses the UP and DOWN arrows to move through the controls.

    private void Control_KeyUp( object sender, KeyEventArgs e )
    {

Google has a nice library for this: https://developers.google.com/webfonts/docs/webfont_loader You can use almost any fonts and the lib will add classes to the html tag.

It even gives you javascript events on when certrain fonts are loaded and active!

Don't forget to serve your fontfiles gzipped! it will certainly speed things up!

It seems the issue is in "-f ($_.Partition.Size/1GB)}}" If you want the value in MB then change the 1GB to 1MB.

Can you test with surefire 2.6 and either configure Surefire with <testFailureIgnore>true</testFailureIgnore>.

Or on the command line:

mvn install -Dmaven.test.failure.ignore=true

If you are using anaconda to go into python environment you should have build up different environment for different python version

The following scripts may help you build up a new environment(running in anaconda prompt)

conda create -n py27 python=2.7  #for version 2.7
activate py27

conda create -n py36 python=3.6  #for version 3.6
activate py36

you may leave the environment back to your global env by typing
deactivate py27 
or 
deactivate py36 

and then you can either switch to different environment using your anaconda UI with @Francisco Camargo 's answer

or you can stick to anaconda prompt using @Dan 's answer

This article describes how to render text in OpenGL using various techniques.

With only using opengl, there are several ways:

• using glBitmap
• using textures
• using display lists

If you want to input a description you can use this. This works on IE 9 and all other browsers.

<input type="text" onclick="if(this.value=='CVC2: '){this.value='';}" onblur="if(this.value==''){this.value='CVC2: ';}" value="CVC2: "/>

I received the same message. My fix included: I deleted all the additional sheets (tabs) in the .csv file, eliminated non-numeric characters, resaved the file as comma delimited and loaded in R v 2.15.0 using standard language:

filename<-read.csv("filename",header=TRUE)

As an additional safeguard, I closed the software and reopened before I loaded the csv.

mv in unix-ish systems, move in dos/windows.

e.g.

C:\> move c:\users\you\somefile.txt   c:\temp\newlocation.txt

and

$ mv /home/you/somefile.txt /tmp/newlocation.txt

Just for fun, here is a GOTO implementation in Java.

Example:

   1 public class GotoDemo {
   2     public static void main(String[] args) {
   3         int i = 3;
   4         System.out.println(i);
   5         i = i - 1;
   6         if (i >= 0) {
   7             GotoFactory.getSharedInstance().getGoto().go(4);
   8         }
   9         
  10         try {
  11             System.out.print("Hell");
  12             if (Math.random() > 0) throw new Exception();            
  13             System.out.println("World!");
  14         } catch (Exception e) {
  15             System.out.print("o ");
  16             GotoFactory.getSharedInstance().getGoto().go(13);
  17         }
  18     }
  19 }

Running it:

$ java -cp bin:asm-3.1.jar GotoClassLoader GotoDemo

   Hello World!

Do I need to add "don't use it!"?

res = request.GET['paymentid'] will raise a KeyError if paymentid is not in the GET data.

Your sample php code checks to see if paymentid is in the POST data, and sets $payID to '' otherwise:

$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''

The equivalent in python is to use the get() method with a default argument:

payment_id = request.POST.get('payment_id', '')

while debugging, this is what I see in the response.GET: <QueryDict: {}>, request.POST: <QueryDict: {}>

It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.

Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

In my IE11, works normally. Version: 11.306.10586.0

We can test if ActiveX works at IE, in this site: http://www.pcpitstop.com/testax.asp

git config --get remote.origin.url

in my case, datas is an objects of Array for more information please Click Here

<% for(let [index,data] of datas.entries() || []){  %>
 Index : <%=index%>
 Data : <%=data%>
<%} %>

You can use like this for check password contain at-least 1 Uppercase, 1 Lowercase, 1 Numeric and 1 special character :

$this->validate($request, [
'name' => 'required|min:3|max:50',
'email' => 'email',
'password' => 'required|confirmed|min:6|regex:/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{6,}$/']);

One important thing related with foreach is that , foreach iteration variable cannot be updated(or assign new value) in loop body.

for example :

List<string> myStrlist = new List<string>() { "Sachin", "Ganguly", "Dravid" };
              foreach(string item in myStrlist)

              {

                  item += " cricket"; // ***Not Possible*** 

              }

You cannot access a local directory from pl/sql. If you use bfile, you will setup a directory (create directory) on the server where Oracle is running where you will need to put your images.

If you want to insert a handful of images from your local machine, you'll need a client side app to do this. You can write your own, but I typically use Toad for this. In schema browser, click onto the table. Click the data tab, and hit + sign to add a row. Double click the BLOB column, and a wizard opens. The far left icon will load an image into the blob:

SQL Developer has a similar feature. See the "Load" link below:

If you need to pull images over the wire, you can do it using pl/sql, but its not straight forward. First, you'll need to setup ACL list access (for security reasons) to allow a user to pull over the wire. See this article for more on ACL setup.

Assuming ACL is complete, you'd pull the image like this:

declare
    l_url varchar2(4000) := 'http://www.oracleimg.com/us/assets/12_c_navbnr.jpg';
    l_http_request   UTL_HTTP.req;
    l_http_response  UTL_HTTP.resp;
    l_raw RAW(2000);
    l_blob BLOB;
begin
   -- Important: setup ACL access list first!

    DBMS_LOB.createtemporary(l_blob, FALSE);

    l_http_request  := UTL_HTTP.begin_request(l_url);
    l_http_response := UTL_HTTP.get_response(l_http_request);

  -- Copy the response into the BLOB.
  BEGIN
    LOOP
      UTL_HTTP.read_raw(l_http_response, l_raw, 2000);
      DBMS_LOB.writeappend (l_blob, UTL_RAW.length(l_raw), l_raw);
    END LOOP;
  EXCEPTION
    WHEN UTL_HTTP.end_of_body THEN
      UTL_HTTP.end_response(l_http_response);
  END;

  insert into my_pics (pic_id, pic) values (102, l_blob);
  commit;

  DBMS_LOB.freetemporary(l_blob); 
end;

Hope that helps.

ImmutableMap does not accept null values whereas Collections.unmodifiableMap() does. In addition it will never change after construction, while UnmodifiableMap may. From the JavaDoc:

An immutable, hash-based Map with reliable user-specified iteration order. Does not permit null keys or values.

Unlike Collections.unmodifiableMap(java.util.Map), which is a view of a separate map which can still change, an instance of ImmutableMap contains its own data and will never change. ImmutableMap is convenient for public static final maps ("constant maps") and also lets you easily make a "defensive copy" of a map provided to your class by a caller.

Assigning questionFrame.frame.size.height= screenSize.height * 0.30 will not reflect anything in the view. because it is a get-only property. If you want to change the frame of questionFrame you can use the below code.

questionFrame.frame = CGRect(x: 0, y: 0, width: 0, height: screenSize.height * 0.70)

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

You need to parse the url first, so it goes like this:

$url = "https://www.example.com/profile#picture";
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'

If you need to parse the actual url of the current browser, you need to request to call the server.

$url = $_SERVER["REQUEST_URI"];
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'

I think the easiest way to do such thing is to resolve the routes later, you could ask the routes via json, for example. Check out that I make a factory out of the $routeProvider during config phase, via $provide, so I can keep using the $routeProvider object in the run phase, and even in controllers.

'use strict';

angular.module('myapp', []).config(function($provide, $routeProvider) {
    $provide.factory('$routeProvider', function () {
        return $routeProvider;
    });
}).run(function($routeProvider, $http) {
    $routeProvider.when('/', {
        templateUrl: 'views/main.html',
        controller: 'MainCtrl'
    }).otherwise({
        redirectTo: '/'
    });

    $http.get('/dynamic-routes.json').success(function(data) {
        $routeProvider.when('/', {
            templateUrl: 'views/main.html',
            controller: 'MainCtrl'
        });
        // you might need to call $route.reload() if the route changed
        $route.reload();
    });
});

This is the suggested Matplotlib 3 solution from the official website HERE:

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x)

ax = plt.subplot(111)
ax.plot(x, y)

# Hide the right and top spines
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

# Only show ticks on the left and bottom spines
ax.yaxis.set_ticks_position('left')
ax.xaxis.set_ticks_position('bottom')

plt.show()

You need convert to number type:

(+Low).toFixed(2)

Check it's value property:

In jQuery (since your tag mentions it):

$('#fileInput').val()

Or in vanilla JavaScript:

document.getElementById('myFileInput').value

There are three choices of padding: valid (no padding), same (or half), full. You can find explanations (in Theano) here: http://deeplearning.net/software/theano/tutorial/conv_arithmetic.html

• Valid or no padding:

The valid padding involves no zero padding, so it covers only the valid input, not including artificially generated zeros. The length of output is ((the length of input) - (k-1)) for the kernel size k if the stride s=1.

• Same or half padding:

The same padding makes the size of outputs be the same with that of inputs when s=1. If s=1, the number of zeros padded is (k-1).

• Full padding:

The full padding means that the kernel runs over the whole inputs, so at the ends, the kernel may meet the only one input and zeros else. The number of zeros padded is 2(k-1) if s=1. The length of output is ((the length of input) + (k-1)) if s=1.

Therefore, the number of paddings: (valid) <= (same) <= (full)

Here's how it should look like in order to return a simple Yes when it's checked.

<input type="checkbox" id="newsletter" name="newsletter" value="Yes" checked>
<label for="newsletter">i want to sign up for newsletter</label>

I also added the text as a label, it means you can click the text as well to check the box. Small but, personally I hate when sites make me aim my mouse at this tiny little check box.

When the form is submitted if the check box is checked $_POST['newsletter'] will equal Yes. Just how you are checking to see if $_POST['name'],$_POST['email'], and $_POST['tel'] are empty you could do the same.

Here is an example of how you would add this into your email on the php side:

Underneath your existing code:

$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];

Add:

$newsletter = $_POST['newsletter'];
if ($newsletter != 'Yes') {
    $newsletter = 'No';
}

If the check box is checked it will add Yes in your email if it was not checked it will add No.

There is a bunch on here:

http://www.webservicex.net/WS/wscatlist.aspx

Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.

Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.

I don't think you could change the style of browsers' default alert boxes.

You need to create your own or use a simple and customizable library like xdialog. Following is a example to customize the alert box. More demos can be found here.

function show_alert() {_x000D_
    xdialog.alert("Hello! I am an alert box!");_x000D_
}

The biggest clue is the rows are all being returned on one line. This indicates line terminators are being ignored or are not present.

You can specify the line terminator for csv_reader. If you are on a mac the lines created will end with \rrather than the linux standard \n or better still the suspenders and belt approach of windows with \r\n.

pandas.read_csv(filename, sep='\t', lineterminator='\r')

You could also open all your data using the codecs package. This may increase robustness at the expense of document loading speed.

import codecs

doc = codecs.open('document','rU','UTF-16') #open for reading with "universal" type set

df = pandas.read_csv(doc, sep='\t')

You could:

SELECT COALESCE(SUM(columnA), 0) FROM my_table WHERE columnB = 1
INTO res;

This happens to work, because your query has an aggregate function and consequently always returns a row, even if nothing is found in the underlying table.

Plain queries without aggregate would return no row in such a case. COALESCE would never be called and couldn't save you. While dealing with a single column we can wrap the whole query instead:

SELECT COALESCE( (SELECT columnA FROM my_table WHERE ID = 1), 0)
INTO res;

Works for your original query as well:

SELECT COALESCE( (SELECT SUM(columnA) FROM my_table WHERE columnB = 1), 0)
INTO res;

More about COALESCE() in the manual.
More about aggregate functions in the manual.
More alternatives in this later post:

• How to return a value from a function if no value is found

create an int array and a list

from array import array
listA = list(range(0,50))
for item in listA:
    print(item)
arrayA = array("i", listA)
for item in arrayA:
    print(item)

It sounds like you are debugging an optimised / release build, despite having the optimised box un-checked. Things you can try are:

• Do a complete rebuild of your solution file (right click on the solution and select Rebuild all)
• While debugging open up the modules window (Debug -> Windows -> Modules) and find your assembly in the list of loaded modules. Check that the Path listed against your loaded assembly is what you expect it to be, and that the modified timestamp of the file indicates that the assembly was actually rebuilt.
• The modules window should also tell you whether or not the loaded module is optimised or not - make sure that the modules window indicates that it is not optimised.

If you cant't see the Modules menu item in the Debug -> Windows menu then you may need to add it in the "Customise..." menu.

<?php
   header("Location: your url");
   exit;
?>

You do it:

console.log('hi')_x000D_
let start = 1_x000D_
setTimeout(function(){_x000D_
  let interval = setInterval(function(){_x000D_
    if(start == 10) clearInterval(interval)_x000D_
    start++_x000D_
    console.log('hello')_x000D_
  }, 3000)_x000D_
}, 3000)

I had the same problem and my cure is to simply enable data binding in my app module's build.gradle.

android { ... dataBinding.enabled = true }

ref - https://halfthought.wordpress.com/2016/03/23/2-way-data-binding-on-android/

Use gettimeofday() or better clock_gettime()

This problem is almost always related to the GDI Object count, User Object count or Handle count and usually not because of an out-of-memory condition on your machine.

When I am tracking one of these bugs, I open ProcessExplorer and watch these columns: Handles, Threads, GDI Objects, USER Objects, Private Bytes, Virtual Size and Working Set.

(In my experience, the problem is usually an object leak due to an event handler holding the object and preventing it from being disposed.)

type on terminal:

nano ~/.bash_profile 

then paste:

export PATH="/Users/yourusername/.composer/vendor/bin:$PATH"

then save (press ctrl+c, press Y, press enter)

now you are ready to use "laravel" on your terminal

This should solve your problem:

I have written a small Java/Android library for comparing version numbers: https://github.com/G00fY2/version-compare

What it basically does is this:

  public int compareVersions(String versionA, String versionB) {
    String[] versionTokensA = versionA.split("\\.");
    String[] versionTokensB = versionB.split("\\.");
    List<Integer> versionNumbersA = new ArrayList<>();
    List<Integer> versionNumbersB = new ArrayList<>();

    for (String versionToken : versionTokensA) {
      versionNumbersA.add(Integer.parseInt(versionToken));
    }
    for (String versionToken : versionTokensB) {
      versionNumbersB.add(Integer.parseInt(versionToken));
    }

    final int versionASize = versionNumbersA.size();
    final int versionBSize = versionNumbersB.size();
    int maxSize = Math.max(versionASize, versionBSize);

    for (int i = 0; i < maxSize; i++) {
      if ((i < versionASize ? versionNumbersA.get(i) : 0) > (i < versionBSize ? versionNumbersB.get(i) : 0)) {
        return 1;
      } else if ((i < versionASize ? versionNumbersA.get(i) : 0) < (i < versionBSize ? versionNumbersB.get(i) : 0)) {
        return -1;
      }
    }
    return 0;
  }

This snippet doesn't offer any error checks or handling. Beside that my library also supports suffixes like "1.2-rc" > "1.2-beta".

To insert a single row of data:

INSERT INTO USERS
VALUES (1, 'Mike', 'Jones');

To do an insert on specific columns (as opposed to all of them) you must specify the columns you want to update.

INSERT INTO USERS (FIRST_NAME, LAST_NAME)
VALUES ('Stephen', 'Jiang');

To insert multiple rows of data in SQL Server 2008 or later:

INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe'),
(3, 'Linda', 'Mitchell'),
(4, 'Jillian', 'Carson'),
(5, 'Garrett', 'Vargas');

To insert multiple rows of data in earlier versions of SQL Server, use "UNION ALL" like so:

INSERT INTO USERS (FIRST_NAME, LAST_NAME)
SELECT 'James', 'Bond' UNION ALL
SELECT 'Miss', 'Moneypenny' UNION ALL
SELECT 'Raoul', 'Silva'

Note, the "INTO" keyword is optional in INSERT queries. Source and more advanced querying can be found here.

Note if you want to count FULL 24h days between 2 dates, datediff can return wrong values for you.

As documentation states:

Only the date parts of the values are used in the calculation.

which results in

select datediff('2016-04-14 11:59:00', '2016-04-13 12:00:00')

returns 1 instead of expected 0.

Solution is using select timestampdiff(DAY, '2016-04-13 11:00:01', '2016-04-14 11:00:00'); (note the opposite order of arguments compared to datediff).

Some examples:

• select timestampdiff(DAY, '2016-04-13 11:00:01', '2016-04-14 11:00:00'); returns 0
• select timestampdiff(DAY, '2016-04-13 11:00:00', '2016-04-14 11:00:00'); returns 1
• select timestampdiff(DAY, '2016-04-13 11:00:00', now()); returns how many full 24h days has passed since 2016-04-13 11:00:00 until now.

Hope it will help someone, because at first it isn't much obvious why datediff returns values which seems to be unexpected or wrong.

Swift 3/4:

func randomNumber(range: ClosedRange<Int> = 1...6) -> Int {
    let min = range.lowerBound
    let max = range.upperBound
    return Int(arc4random_uniform(UInt32(1 + max - min))) + min
}

This is succinct and readable:

"MyProperty" -in $MyObject.PSobject.Properties.Name

We can put it in a function:

function HasProperty($object, $propertyName)
{
    $propertyName -in $object.PSobject.Properties.Name
}

Intel HD Graphics is usually the on-CPU graphics chip in newer Core i3/i5/i7 processors.

As far as I know it doesn't support CUDA (which is a proprietary NVidia technology), but OpenCL is supported by NVidia, ATi and Intel.

This code will work for you, because i had a simmilar problem and this worked for me. :)

1- Override Onstart() method in your fragment-dialog class.

@Override
public void onStart() {
    super.onStart();
    final AlertDialog D = (AlertDialog) getDialog();
    if (D != null) {
        Button positive = (Button) D.getButton(Dialog.BUTTON_POSITIVE);
        positive.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                if (edittext.equals("")) {
   Toast.makeText(getActivity(), "EditText empty",Toast.LENGTH_SHORT).show();
                } else {
                D.dismiss(); //dissmiss dialog
                }
            }
        });
    }
}

It is just not a valid Java syntax. You can do

names = new String[] {"Ankit","Bohra","Xyz"};

Have you checked this http://support.microsoft.com/kb/209805? In particular, whether you have Msrd3x40.dll.

You may also like to check that you have the latest version of Jet: http://support.microsoft.com/kb/239114

Of course it does. After replacing the variable, it reads [ !-z ], which is not a valid [ command. Use double quotes, or [[.

if [ ! -z "$errorstatus" ]

if [[ ! -z $errorstatus ]]

Php has a super sexy function for this, just pass the array to it:

$json = json_encode($var);

$.ajax({
url:"Example.php",
type:"POST",
dataType : "json",
success:function(msg){
    console.info(msg);
}
});

simples :)

I add in myApp.java, after @SpringBootApplication

@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

And changed

@SpringBootApplication => @Configuration

So, I have this in my main class (myApp.java)

package br.com.company.project.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class SomeApplication {

public static void main(String[] args) {
    SpringApplication.run(SomeApplication.class, args);
}

}

And work for me! =)

in my case i have saved a json file with a space like this

google-services .json

and the right one is

google-services.json

and also take care you do not put (_) instead of (-)

may help some one.

alternatively you can retrieve DOM properties with .prop

here is sample code for select box

if( ctrl.prop('type') == 'select-one' ) { // for single select }

if( ctrl.prop('type') == 'select-multiple' ) { // for multi select }

for textbox

  if( ctrl.prop('type') == 'text' ) { // for text box }

Typedef allows items to be implicitly assigned to types they are not. Some people try to get around this with extensions; read here at IBM for an explanation of why this is a bad idea.

Edit: While strong type inference is a useful thing, I don't think (and hope we won't) see typedef rearing it's ugly head in managed languages (ever?).

Edit 2: In C#, you can use a using statement like this at the top of a source file. It's used so you don't have to do the second item shown. The only time you see the name change is when a scope introduces a name collision between two types. The renaming is limited to one file, outside of which every variable/parameter type which used it is known by its full name.

The easiest way to freeze the UI would be to make the AJAX call synchronous.

Usually synchronous AJAX calls defeat the purpose of using AJAX because it freezes the UI, but if you want to prevent the user from interacting with the UI, then do it.

WHERE IsNumeric(MY_FIELD) = 1 AND CAST(MY_FIELD as VARCHAR(5)) NOT LIKE '%.%'

That is probably the simplest solution. Unless your MY_FIELD contains .00 or something of that sort. In which case, cast it to a float to remove any trailing .00s

Simple Swift 3 solution

Add UITextViewDelegate to your class

Set yourTextView.delegate = self

Create placeholderLabel and position it inside yourTextView

Now just animate placeholderLabel.alpha on textViewDidChange:

  func textViewDidChange(_ textView: UITextView) {
    let newAlpha: CGFloat = textView.text.isEmpty ? 1 : 0
    if placeholderLabel.alpha != newAlpha {
      UIView.animate(withDuration: 0.3) {
        self.placeholderLabel.alpha = newAlpha
      }
    }
  }

you might have to play with placeholderLabel position to set it up right, but that shouldn't be too hard

If you want to clone into the current folder, you should try this:

git clone https://github.com/example/example.git ./

I had this same issue when running from Eclipse. To fix the issue I went into the Configure Build Path and removed the src folder from the build path. Then closed and reopened the project. Then I added the src folder to the build path. The src folder contained the java class I was trying to access.

I resolved this issue myself. The problem was I had the solution opened in another place. After closing it it works

A simple solution that could work in some cases is to create and $compile a wrapper and then append your original element to it.

Something like...

link: function(scope, elem, attr){
    var wrapper = angular.element('<div tooltip></div>');
    elem.before(wrapper);
    $compile(wrapper)(scope);
    wrapper.append(elem);
}

This solution has the advantage that it keeps things simple by not recompiling the original element.

This wouldn't work if any of the added directive's require any of the original element's directives or if the original element has absolute positioning.

As far as I understand getters and setters are to improve encapsulation. There is nothing complex about them in C#.

You define a property of on object like this:

int m_colorValue = 0;
public int Color 
{
   set { m_colorValue = value; }
   get { return m_colorValue; }
}

This is the most simple use. It basically sets an internal variable or retrieves its value. You use a Property like this:

someObject.Color = 222; // sets a color 222
int color = someObject.Color // gets the color of the object

You could eventually do some processing on the value in the setters or getters like this:

public int Color 
{
   set { m_colorValue = value + 5; }
   get { return m_colorValue  - 30; }
}

if you skip set or get, your property will be read or write only. That's how I understand the stuff.

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

dG will delete from the current line to the end of file

dCtrl+End will delete from the cursor to the end of the file

But if this file is as large as you say, you may be better off reading the first few lines with head rather than editing and saving the file.

head hugefile > firstlines

(If you are on Windows you can use the Win32 port of head)

If you have an Eloquent Relationship between your models you can do something like that:

@foreach ($ships as  $ship)
<select name="data[]" class="form-control" multiple>
    @foreach ($goods_containers as  $container)
        <option value="{{ $container->id }}"
                @if ($ship->containers->contains('container_id',$container->id ) ))
                selected="selected"
                @endif
        >{{ $container->number}}</option>
    @endforeach
</select>

"matt b" has it right, but to be specific, the "install" goal copies your built target to the local repository on your file system; useful for small changes across projects not currently meant for the full group.

The "deploy" goal uploads it to your shared repository for when your work is finished, and then can be shared by other people who require it for their project.

In your case, it seems that "install" is used to make the management of the deployment easier since CI's local repo is the shared repo. If CI was on another box, it would have to use the "deploy" goal.

In a project I worked at we solved this problem by implement something we called 'Batch' requests. We defined a path /batch where we accepted json in the following format:

[  
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 1,
         binder: 1
      }
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 5,
         binder: 8
      }
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 6,
         binder: 3
      }
   },
]

The response have the status code 207 (Multi-Status) and looks like this:

[  
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 1,
         binder: 1
      }
      status: 200
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         error: {
            msg: 'A document with doc_number 5 already exists'
            ...
         }
      },
      status: 409
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 6,
         binder: 3
      },
      status: 200
   },
]

You could also add support for headers in this structure. We implemented something that proved useful which was variables to use between requests in a batch, meaning we can use the response from one request as input to another.

Facebook and Google have similar implementations:
https://developers.google.com/gmail/api/guides/batch
https://developers.facebook.com/docs/graph-api/making-multiple-requests

When you want to create or update a resource with the same call I would use either POST or PUT depending on the case. If the document already exist, do you want the entire document to be:

1. Replaced by the document you send in (i.e. missing properties in request will be removed and already existing overwritten)?
2. Merged with the document you send in (i.e. missing properties in request will not be removed and already existing properties will be overwritten)?

In case you want the behavior from alternative 1 you should use a POST and in case you want the behavior from alternative 2 you should use PUT.

http://restcookbook.com/HTTP%20Methods/put-vs-post/

As people already suggested you could also go for PATCH, but I prefer to keep API's simple and not use extra verbs if they are not needed.

You can use monitorEvents function.

Just inspect your element (right mouse click ? Inspect on visible element or go to Elements tab in Chrome Developer Tools and select wanted element) then go to Console tab and write:

monitorEvents($0)

Now when you move mouse over this element, focus or click it, the name of the fired event will be displayed with its data.

To stop getting this data just write this to console:

unmonitorEvents($0)

$0 is just the last DOM element selected by Chrome Developer Tools. You can pass any other DOM object there (for example result of getElementById or querySelector).

You can also specify event "type" as second parameter to narrow monitored events to some predefined set. For example:

monitorEvents(document.body, 'mouse')

List of this available types is here.

I made a small gif that illustrates how this feature works:

UNIX timestamp is number of seconds since 00:00:00 UTC on January 1, 1970 (according to Wikipedia).

Argument of Date object in Javascript is number of miliseconds since 00:00:00 UTC on January 1, 1970 (according to W3Schools Javascript documentation).

See code below for example:

    function tm(unix_tm) {
        var dt = new Date(unix_tm*1000);
        document.writeln(dt.getHours() + '/' + dt.getMinutes() + '/' + dt.getSeconds() + ' -- ' + dt + '<br>');

    }

tm(60);
tm(86400);

gives:

1/1/0 -- Thu Jan 01 1970 01:01:00 GMT+0100 (Central European Standard Time)
1/0/0 -- Fri Jan 02 1970 01:00:00 GMT+0100 (Central European Standard Time)

As I knowit, encapsulation is hiding data of classes in themselves, and only making it accessible via setters / getters, if they must be accessed from the outer world.

Abstraction is the class design for itself.

Means, how You create Your class tree, which methods are general ones, which are inherited, which can be overridden,which attributes are only on private level, or on protected, how Do You build up Your class inheritance tree, Do You use final classes, abtract classes, interface-implementation.

Abstraction is more placed the oo-design phase, while encapsulation also enrolls into developmnent-phase.

Use the following code:

ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");
error_log( "Hello, errors!" );

Then watch the file:

tail -f /tmp/php-error.log

Or update php.ini as described in this blog entry from 2008.

you can try:

services:
  nameis:
    container_name: hi_my
    build: .
    image: hi_my_nameis:v1.0.0

SELECT CompanyName, 
    CASE WHEN Country IN ('USA', 'Canada') THEN 'North America'
         WHEN Country = 'Brazil' THEN 'South America'
         ELSE 'Europe' END AS Continent
FROM Suppliers
ORDER BY CompanyName;

The direct answer to this question is:

if(rows.Any()) //prevent IndexOutOfRangeException for empty list
{
    rows.RemoveAt(rows.Count - 1);
}

However... in the specific case of this question, it makes more sense not to add the row in the first place:

Row row = new Row();
//...      

if (!row.cell[0].Equals("Something"))
{
    rows.Add(row);
}

TBH, I'd go a step further by testing "Something" against user."", and not even instantiating a Row unless the condition is satisfied, but seeing as user."" won't compile, I'll leave that as an exercise for the reader.

ITroubs answer doesn't deal with the left over seconds when you want to use this code to convert an amount of seconds to a time format like hours : minutes : seconds

Here is what I did to deal with this: (This also adds a leading zero to one-digit minutes and seconds)

$seconds = 3921; //example

$hours = floor($seconds / 3600);
$mins = floor(($seconds - $hours*3600) / 60);
$s = $seconds - ($hours*3600 + $mins*60);

$mins = ($mins<10?"0".$mins:"".$mins);
$s = ($s<10?"0".$s:"".$s); 

$time = ($hours>0?$hours.":":"").$mins.":".$s;

$time will contain "1:05:21" in this example.

Use a PHP Excel for generatingExcel file. You can find a good one called PHPExcel here: https://github.com/PHPOffice/PHPExcel

And for PDF generation use http://princexml.com/

In case if you are still stumbling over this question. Nowadays things look nicer with Java 8:

try {
  Files.lines(Paths.get(targetsFile)).forEach(
    s -> {
      System.out.println(s);
      // do more stuff with s
    }
  );
} catch (IOException exc) {
  exc.printStackTrace();
}

When we apply local url, ErrorDocument directive expect the full path from DocumentRoot. There fore,

hi you can try doing this

link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, {class: 'dock-item'}

or even

link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, class: 'dock-item'

note that the position of the curly braces is very important, because if you miss them out, rails will assume they form a single hash parameters (read more about this here)

and according to the api for link_to:

link_to(name, options = {}, html_options = nil)

1. the first parameter is the string to be shown (or it can be an image_tag as well)
2. the second is the parameter for the url of the link
3. the last item is the optional parameter for declaring the html tag, e.g. class, onchange, etc.

hope it helps! =)

Your code looks great, the only thing i see is that you did not include the collapsed class in your button selector. http://www.bootply.com/cpHugxg2f8 Note: Requires JavaScript plugin If JavaScript is disabled and the viewport is narrow enough that the navbar collapses, it will be impossible to expand the navbar and view the content within the .navbar-collapse.

The responsive navbar requires the collapse plugin to be included in your version of Bootstrap.

<div class="navbar-wrapper">
      <div class="container">

        <nav class="navbar navbar-inverse navbar-static-top">
          <div class="container">

I know this doesn't answer OPs exact question but I came here with the same symptom but a different cause:

I had the .scss files of Slick Slider included like this:

@import "../../../node_modules/slick-carousel/slick/slick.scss";

On closer inspection it turned out that the it was trying to load the font from an invalid location (<host>/assets/css/fonts/slick.woff), the way it was referenced from the stylesheet.

I ended up simply copying the /font/ to my assets/css/ and the issue was resolved for me.

This is a method of the java.awt.Component class. It is used to set the position and size of a component:

setBounds

public void setBounds(int x,
                  int y,
                  int width,
                  int height) 

Moves and resizes this component. The new location of the top-left corner is specified by x and y, and the new size is specified by width and height. Parameters:

• x - the new x-coordinate of this component
• y - the new y-coordinate of this component
• width - the new width of this component
• height - the new height of this component

x and y as above correspond to the upper left corner in most (all?) cases.

It is a shortcut for setLocation and setSize.

This generally only works if the layout/layout manager are non-existent, i.e. null.

in addition to all the answers that other friends have , if somebody who is looking this post is looking for a way to delete a "Folder" not a "file" , should take care that Folders must delete by php rmdir() function and if u want to delete a "Folder" by unlink() , u will encounter with a wrong Warning message that says "permission denied"

however u can make folders & files by mkdir() but the way u delete folders (rmdir()) is different from the way you delete files(unlink())

eventually as a fact:

in many programming languages, any permission related error may not directly means an actual permission issue

for example, if you want to readSync a file that doesn't exist with node fs module you will encounter a wrong EPERM error

DateTime.AddDays does that:

DateTime expires = yourDate.AddDays(30);

To know the react version, Open package.json file in root folder, search the keywork react. You will see like "react": "^16.4.0",

As addition to the accepted answer:

To see the hashes you need to use the suggested command "git checkout hash", you can use git log. Hoewever, depending on what you need, there is an easier way than copy/pasting hashes.

You can use git log --oneline to read many commit messages in a more compressed format.

Lets say you see this a one-line list of the commits with minimal information and only partly visible hashes:

hash111 (HEAD -> master, origin/master, origin/HEAD)
hash222 last commit
hash333 I want this one
hash444 did something
....

If you want last commit, you can use git checkout master^. The ^ gives you the commit before the master. So hash222.

If you want the n-th last commit, you can use git checkout master~n. For example, using git checkout master~2would give you the commit hash333.

We modify a Meouw function to be used with keyup, because when you are using an input it can be more helpful.

Check this:

Hey there!, @heridev and I created a small function in jQuery.

You can try next:

HTML

<input type="text" name="one" class="two-digits"><br>
<input type="text" name="two" class="two-digits">?

jQuery

// apply the two-digits behaviour to elements with 'two-digits' as their class
$( function() {
    $('.two-digits').keyup(function(){
        if($(this).val().indexOf('.')!=-1){         
            if($(this).val().split(".")[1].length > 2){                
                if( isNaN( parseFloat( this.value ) ) ) return;
                this.value = parseFloat(this.value).toFixed(2);
            }  
         }            
         return this; //for chaining
    });
});

I'm not really sure if this adds anything but,

Caller saved means that the caller has to save the registers because they will be clobbered in the call and have no choice but to be left in a clobbered state after the call returns (for instance, the return value being in eax for cdecl. It makes no sense for the return value to be restored to the value before the call by the callee, because it is a return value).

Callee saved means that the callee has to save the registers and then restore them at the end of the call because they have the guarantee to the caller of containing the same values after the function returns, and it is possible to restore them, even if they are clobbered at some point during the call.

The issue with the above definition though is that for instance on Wikipedia cdecl, it says eax, ecx and edx are caller saved and rest are callee saved, this suggests that the caller must save all 3 of these registers, when it might not if none of these registers were used by the caller in the first place. In which case caller 'saved' becomes a misnomer, but 'call clobbered' still correctly applies. This is the same with 'the rest' being called callee saved. It implies that all other x86 registers will be saved and restored by the callee when this is not the case if some of the registers are never used in the call anyway. With cdecl, eax:edx may be used to return a 64 bit value. I'm not sure why ecx is also caller saved if needed, but it is.

Solution with brew worked only after the following: in your php.ini

nano /private/etc/php.ini

add this line:

extension="/usr/local/Cellar/php53-mcrypt/5.3.26/mcrypt.so"

Warning! Set the correct PHP version.

This looks a bit strange, but...

stringName == null || "".equals(stringName)

Never had any issues doing it this way, plus it's a safer way to check while avoiding potential null point exceptions.

Take a look at the Cursor.Position Property. It should get you started.

private void MoveCursor()
{
   // Set the Current cursor, move the cursor's Position,
   // and set its clipping rectangle to the form. 

   this.Cursor = new Cursor(Cursor.Current.Handle);
   Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
   Cursor.Clip = new Rectangle(this.Location, this.Size);
}

You CANNOT do this - you cannot attach/detach or backup/restore a database from a newer version of SQL Server down to an older version - the internal file structures are just too different to support backwards compatibility. This is still true in SQL Server 2014 - you cannot restore a 2014 backup on anything other than another 2014 box (or something newer).

You can either get around this problem by

• using the same version of SQL Server on all your machines - then you can easily backup/restore databases between instances

• otherwise you can create the database scripts for both structure (tables, view, stored procedures etc.) and for contents (the actual data contained in the tables) either in SQL Server Management Studio (Tasks > Generate Scripts) or using a third-party tool

• or you can use a third-party tool like Red-Gate's SQL Compare and SQL Data Compare to do "diffing" between your source and target, generate update scripts from those differences, and then execute those scripts on the target platform; this works across different SQL Server versions.

The compatibility mode setting just controls what T-SQL features are available to you - which can help to prevent accidentally using new features not available in other servers. But it does NOT change the internal file format for the .mdf files - this is NOT a solution for that particular problem - there is no solution for restoring a backup from a newer version of SQL Server on an older instance.

Receive POST and GET request in nodejs :

1).Server

    var http = require('http');
    var server = http.createServer ( function(request,response){

    response.writeHead(200,{"Content-Type":"text\plain"});
    if(request.method == "GET")
        {
            response.end("received GET request.")
        }
    else if(request.method == "POST")
        {
            response.end("received POST request.");
        }
    else
        {
            response.end("Undefined request .");
        }
});

server.listen(8000);
console.log("Server running on port 8000");

2). Client :

var http = require('http');

var option = {
    hostname : "localhost" ,
    port : 8000 ,
    method : "POST",
    path : "/"
} 

    var request = http.request(option , function(resp){
       resp.on("data",function(chunck){
           console.log(chunck.toString());
       }) 
    })
    request.end();

The PrintWriter class can actually create the file for you.

This example works in JDK 1.7+.

// This will create the file.txt in your working directory.

PrintWriter printWriter = null;

try {

    printWriter = new PrintWriter("file.txt", "UTF-8");
    // The second parameter determines the encoding. It can be
    // any valid encoding, but I used UTF-8 as an example.

} catch (FileNotFoundException | UnsupportedEncodingException error) {
    error.printStackTrace();
}

printWriter.println("Write whatever you like in your file.txt");

// Make sure to close the printWriter object otherwise nothing
// will be written to your file.txt and it will be blank.
printWriter.close();

For a list of valid encodings, see the documentation.

Alternatively, you can just pass the file path to the PrintWriter class without declaring the encoding.

In MySQL, the word 'type' is a Reserved Word.

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

It's a C trigraph. ??! is |, so ??!??! is the operator ||

To sum with decimal use this:

In the javascript change parseInt with parseFloat and add this line tot.toFixed(2); for this result:

    function findTotal(){
    var arr = document.getElementsByName('qty');
    var tot=0;
    for(var i=0;i<arr.length;i++){
        if(parseFloat(arr[i].value))
            tot += parseFloat(arr[i].value);
    }
    document.getElementById('total').value = tot;
    tot.toFixed(2);
}

Use step=".01" min="0" type="number" in the input filed

Qty1 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty1"/><br>
Qty2 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty2"/><br>
Qty3 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty3"/><br>
Qty4 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty4"/><br>
Qty5 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty5"/><br>
Qty6 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty6"/><br>
Qty7 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty7"/><br>
Qty8 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty8"/><br>
<br><br>
Total : <input type="number" step=".01" min="0" name="total" id="total"/>

For those who want a summary,

android:minSdkVersion

is minimum version till your application supports. If your device has lower version of android , app will not install.

while,

android:targetSdkVersion

is the API level till which your app is designed to run. Means, your phone's system don't need to use any compatibility behaviours to maintain forward compatibility because you have tested against till this API.

Your app will still run on Android versions higher than given targetSdkVersion but android compatibility behaviour will kick in.

Freebie -

android:maxSdkVersion

if your device's API version is higher, app will not install. Ie. this is the max API till which you allow your app to install.

ie. for MinSDK -4, maxSDK - 8, targetSDK - 8 My app will work on minimum 1.6 but I also have used features that are supported only in 2.2 which will be visible if it is installed on a 2.2 device. Also, for maxSDK - 8, this app will not install on phones using API > 8.

At the time of writing this answer, Android documentation was not doing a great job at explaining it. Now it is very well explained. Check it here

Format strings can make hexdump behave exactly as you want it to (no whitespace at all, byte by byte):

hexdump -ve '1/1 "%.2x"'

1/1 means "each format is applied once and takes one byte", and "%.2x" is the actual format string, like in printf. In this case: 2-character hexadecimal number, leading zeros if shorter.

This will return what you asked, but I wouldnt recommend using css like this. Use external CSS instead of inline css.

$("tr[id='pDetails']").attr("style").split(':')[1];

I'd iterate through the options, comparing the text to what I want to be selected, then set the selected attribute on that option. Once you find the correct one, terminate the iteration (unless you have a multiselect).

 $('#dropdown').find('option').each( function() {
      var $this = $(this);
      if ($this.text() == 'B') {
         $this.attr('selected','selected');
         return false;
      }
 });

You can use a data: URL to embed a Base64 encoded version of an image. But it's not very efficient and wouldn't recommend embedding large images. Any reason linking to another file is not feasible?

    public static void GetSection()
    {
        Configuration = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json")
            .Build();

        string BConfig = Configuration.GetSection("ConnectionStrings")["BConnection"];

    }

Great sadness: neither Cloneable/clone nor a constructor are great solutions: I DON'T WANT TO KNOW THE IMPLEMENTING CLASS!!! (e.g. - I have a Map, which I want copied, using the same hidden MumbleMap implementation) I just want to make a copy, if doing so is supported. But, alas, Cloneable doesn't have the clone method on it, so there is nothing to which you can safely type-cast on which to invoke clone().

Whatever the best "copy object" library out there is, Oracle should make it a standard component of the next Java release (unless it already is, hidden somewhere).

Of course, if more of the library (e.g. - Collections) were immutable, this "copy" task would just go away. But then we would start designing Java programs with things like "class invariants" rather than the verdammt "bean" pattern (make a broken object and mutate until good [enough]).

its too simple, you can just type "cache:" before the URL of the page. for example if you want to check the last webcache of this page simply type on URL bar cache:http://stackoverflow.com/questions/4560400/how-can-i-get-the-google-cache-age-of-any-url-or-web-page

this will show you the last webcache of the page.see here:

But remember, the caching of a webpage will only show if the page is already indexed on search engine(Google). for this you need to check the meta robot tag of that page.

I ran into a similar problem while creating a library to handle authentication. I want the app owner using my library to be able to register a callback with the library for checking authorization against LDAP groups the authenticated person is in. The configuration is getting passed in as a config.py file that gets imported and contains a dict with all the config parameters.

I got this to work:

>>> class MyClass(object):
...     def target_func(self):
...         print "made it!"
...    
...     def __init__(self,config):
...         self.config = config
...         self.config['funcname'] = getattr(self,self.config['funcname'])
...         self.config['funcname']()
... 
>>> instance = MyClass({'funcname':'target_func'})
made it!

Is there a pythonic-er way to do this?

Assuming no SecurityManager is preventing you from doing this, you can use setAccessible to get around private and resetting the modifier to get rid of final, and actually modify a private static final field.

Here's an example:

import java.lang.reflect.*;

public class EverythingIsTrue {
   static void setFinalStatic(Field field, Object newValue) throws Exception {
      field.setAccessible(true);

      Field modifiersField = Field.class.getDeclaredField("modifiers");
      modifiersField.setAccessible(true);
      modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);

      field.set(null, newValue);
   }
   public static void main(String args[]) throws Exception {      
      setFinalStatic(Boolean.class.getField("FALSE"), true);

      System.out.format("Everything is %s", false); // "Everything is true"
   }
}

Assuming no SecurityException is thrown, the above code prints "Everything is true".

What's actually done here is as follows:

• The primitive boolean values true and false in main are autoboxed to reference type Boolean "constants" Boolean.TRUE and Boolean.FALSE
• Reflection is used to change the public static final Boolean.FALSE to refer to the Boolean referred to by Boolean.TRUE
• As a result, subsequently whenever a false is autoboxed to Boolean.FALSE, it refers to the same Boolean as the one refered to by Boolean.TRUE
• Everything that was "false" now is "true"

Related questions

• How to limit setAccessible to only “legitimate” uses?
  • Has examples of messing with Integer's cache, mutating a String, etc

Caveats

Extreme care should be taken whenever you do something like this. It may not work because a SecurityManager may be present, but even if it doesn't, depending on usage pattern, it may or may not work.

JLS 17.5.3 Subsequent Modification of Final Fields

In some cases, such as deserialization, the system will need to change the final fields of an object after construction. final fields can be changed via reflection and other implementation dependent means. The only pattern in which this has reasonable semantics is one in which an object is constructed and then the final fields of the object are updated. The object should not be made visible to other threads, nor should the final fields be read, until all updates to the final fields of the object are complete. Freezes of a final field occur both at the end of the constructor in which the final field is set, and immediately after each modification of a final field via reflection or other special mechanism.

Even then, there are a number of complications. If a final field is initialized to a compile-time constant in the field declaration, changes to the final field may not be observed, since uses of that final field are replaced at compile time with the compile-time constant.

Another problem is that the specification allows aggressive optimization of final fields. Within a thread, it is permissible to reorder reads of a final field with those modifications of a final field that do not take place in the constructor.

See also

• JLS 15.28 Constant Expression
  • It's unlikely that this technique works with a primitive private static final boolean, because it's inlineable as a compile-time constant and thus the "new" value may not be observable

Appendix: On the bitwise manipulation

Essentially,

field.getModifiers() & ~Modifier.FINAL

turns off the bit corresponding to Modifier.FINAL from field.getModifiers(). & is the bitwise-and, and ~ is the bitwise-complement.

See also

• Wikipedia/Bitwise operation

Remember Constant Expressions

Still not being able to solve this?, have fallen onto depression like I did for it? Does your code looks like this?

public class A {
    private final String myVar = "Some Value";
}

Reading the comments on this answer, specially the one by @Pshemo, it reminded me that Constant Expressions are handled different so it will be impossible to modify it. Hence you will need to change your code to look like this:

public class A {
    private final String myVar;

    private A() {
        myVar = "Some Value";
    }
}

if you are not the owner of the class... I feel you!

In June 2016 Instagram made most of the functionality of their API available only to applications that have passed a review process. They still however provide JSON data through the web interface, and you can add the parameter __a=1 to a URL to only include the JSON data.

max=
while :;do
  c=$(curl -s "https://www.instagram.com/username/?__a=1&max_id=$max")
  jq -r '.user.media.nodes[]?|.display_src'<<<"$c"
  max=$(jq -r .user.media.page_info.end_cursor<<<"$c")
  jq -e .user.media.page_info.has_next_page<<<"$c">/dev/null||break
done

Edit: As mentioned in the comment by alnorth29, the max_id parameter is now ignored. Instagram also changed the format of the response, and you need to perform additional requests to get the full-size URLs of images in the new-style posts with multiple images per post. You can now do something like this to list the full-size URLs of images on the first page of results:

c=$(curl -s "https://www.instagram.com/username/?__a=1")
jq -r '.graphql.user.edge_owner_to_timeline_media.edges[]?|.node|select(.__typename!="GraphSidecar").display_url'<<<"$c"
jq -r '.graphql.user.edge_owner_to_timeline_media.edges[]?|.node|select(.__typename=="GraphSidecar")|.shortcode'<<<"$c"|while read l;do
  curl -s "https://www.instagram.com/p/$l?__a=1"|jq -r '.graphql.shortcode_media|.edge_sidecar_to_children.edges[]?.node|.display_url'
done

To make a list of the shortcodes of each post made by the user whose profile is opened in the frontmost tab in Safari, I use a script like this:

sjs(){ osascript -e'{on run{a}','tell app"safari"to do javascript a in document 1',end} -- "$1";}

while :;do
  sjs 'o="";a=document.querySelectorAll(".v1Nh3 a");for(i=0;e=a[i];i++){o+=e.href+"\n"};o'>>/tmp/a
  sjs 'window.scrollBy(0,window.innerHeight)'
  sleep 1
done

In case anyone had the same problem: check this as @PravinS suggested. I used the exact same code as shown there and it worked for me perfectly.

This is the relevant part of the server code that helped:

if (isset($_POST['btnUpload']))
{
$url = "URL_PATH of upload.php"; // e.g. http://localhost/myuploader/upload.php // request URL
$filename = $_FILES['file']['name'];
$filedata = $_FILES['file']['tmp_name'];
$filesize = $_FILES['file']['size'];
if ($filedata != '')
{
    $headers = array("Content-Type:multipart/form-data"); // cURL headers for file uploading
    $postfields = array("filedata" => "@$filedata", "filename" => $filename);
    $ch = curl_init();
    $options = array(
        CURLOPT_URL => $url,
        CURLOPT_HEADER => true,
        CURLOPT_POST => 1,
        CURLOPT_HTTPHEADER => $headers,
        CURLOPT_POSTFIELDS => $postfields,
        CURLOPT_INFILESIZE => $filesize,
        CURLOPT_RETURNTRANSFER => true
    ); // cURL options
    curl_setopt_array($ch, $options);
    curl_exec($ch);
    if(!curl_errno($ch))
    {
        $info = curl_getinfo($ch);
        if ($info['http_code'] == 200)
            $errmsg = "File uploaded successfully";
    }
    else
    {
        $errmsg = curl_error($ch);
    }
    curl_close($ch);
}
else
{
    $errmsg = "Please select the file";
}
}

html form should look something like:

<form action="uploadpost.php" method="post" name="frmUpload" enctype="multipart/form-data">
<tr>
  <td>Upload</td>
  <td align="center">:</td>
  <td><input name="file" type="file" id="file"/></td>
</tr>
<tr>
  <td>&nbsp;</td>
  <td align="center">&nbsp;</td>
  <td><input name="btnUpload" type="submit" value="Upload" /></td>
</tr>

None of the above solutions worked for me. But this did:

myImage.Source = new BitmapImage(new Uri(@"/Images/foo.png", UriKind.Relative));

The ID you are trying is an serverside.

That is going to render in the browser differently.

try to get the ID by watching the html in the Browser.

var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;

this may works.

Or do that ClientID method. That also works but ultimately the browser will get the same thing what i had written.

The While statement will not execute until after form1 is closed - as it is outside the main message loop.

Remove it and change the first bit of code to:

private void button1_Click_1(object sender, EventArgs e)  
{  
    if (richTextBox1.Text != null)  
    {  
        this.Visible=false;
        Form2 form2 = new Form2();
        form2.show();
    }  
    else MessageBox.Show("Insert Attributes First !");  

}

This is not the best way to achieve what you are looking to do though. Instead consider the Wizard design pattern.

Alternatively you could implement a custom ApplicationContext that handles the lifetime of both forms. An example to implement a splash screen is here, which should set you on the right path.

http://www.codeproject.com/KB/cs/applicationcontextsplash.aspx?display=Print

Its working fine

NSString *dateString = @"10/10/2010";//Date 
NSArray* dateArray = [dateString componentsSeparatedByString: @"/"];
NSString* dayString = [dateArray objectAtIndex: 0];

use DateTime.ParseExact

string strDate = "24/01/2013";
DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", null)

• DateTime.ParseExact

null will use the current culture, which is somewhat dangerous. Try to supply a specific culture

DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", CultureInfo.InvariantCulture)

You've got two ways to go forward:

JSONP

If this API supports JSONP, the easiest way to fix this issue is to add &callback to the end of the URL. You can also try &callback=. If that doesn't work, it means the API does not support JSONP, so you must try the other solution.

Proxy Script

You can create a proxy script on the same domain as your website in order to avoid the cross-origin issues. This will only work with HTTP URLs, not HTTPS URLs, but it shouldn't be too difficult to modify if you need that.

<?php
// File Name: proxy.php
if (!isset($_GET['url'])) {
    die(); // Don't do anything if we don't have a URL to work with
}
$url = urldecode($_GET['url']);
$url = 'http://' . str_replace('http://', '', $url); // Avoid accessing the file system
echo file_get_contents($url); // You should probably use cURL. The concept is the same though

Then you just call this script with jQuery. Be sure to urlencode the URL.

$.ajax({
    url      : 'proxy.php?url=http%3A%2F%2Fapi.master18.tiket.com%2Fsearch%2Fautocomplete%2Fhotel%3Fq%3Dmah%26token%3D90d2fad44172390b11527557e6250e50%26secretkey%3D83e2f0484edbd2ad6fc9888c1e30ea44%26output%3Djson',
    type     : 'GET',
    dataType : 'json'
}).done(function(data) {
    console.log(data.results.result[1].category); // Do whatever you want here
});

The Why

You're getting this error because of XMLHttpRequest same origin policy, which basically boils down to a restriction of ajax requests to URLs with a different port, domain or protocol. This restriction is in place to prevent cross-site scripting (XSS) attacks.

More Information

Our solutions by pass these problems in different ways.

JSONP uses the ability to point script tags at JSON (wrapped in a javascript function) in order to receive the JSON. The JSONP page is interpreted as javascript, and executed. The JSON is passed to your specified function.

The proxy script works by tricking the browser, as you're actually requesting a page on the same origin as your page. The actual cross-origin requests happen server-side.

See RFC 5322: Internet Message Format and, to a lesser extent, RFC 5321: Simple Mail Transfer Protocol.

RFC 822 also covers email addresses, but it deals mostly with its structure:

 addr-spec   =  local-part "@" domain        ; global address     
 local-part  =  word *("." word)             ; uninterpreted
                                             ; case-preserved

 domain      =  sub-domain *("." sub-domain)     
 sub-domain  =  domain-ref / domain-literal     
 domain-ref  =  atom                         ; symbolic reference

And as usual, Wikipedia has a decent article on email addresses:

The local-part of the email address may use any of these ASCII characters:

• uppercase and lowercase Latin letters A to Z and a to z;
• digits 0 to 9;
• special characters !#$%&'*+-/=?^_`{|}~;
• dot ., provided that it is not the first or last character unless quoted, and provided also that it does not appear consecutively unless quoted (e.g. [email protected] is not allowed but "John..Doe"@example.com is allowed);
• space and "(),:;<>@[\] characters are allowed with restrictions (they are only allowed inside a quoted string, as described in the paragraph below, and in addition, a backslash or double-quote must be preceded by a backslash);
• comments are allowed with parentheses at either end of the local-part; e.g. john.smith(comment)@example.com and (comment)[email protected] are both equivalent to [email protected].

In addition to ASCII characters, as of 2012 you can use international characters above U+007F, encoded as UTF-8 as described in the RFC 6532 spec and explained on Wikipedia. Note that as of 2019, these standards are still marked as Proposed, but are being rolled out slowly. The changes in this spec essentially added international characters as valid alphanumeric characters (atext) without affecting the rules on allowed & restricted special characters like !# and @:.

For validation, see Using a regular expression to validate an email address.

The domain part is defined as follows:

The Internet standards (Request for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters a through z (in a case-insensitive manner), the digits 0 through 9, and the hyphen (-). The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or blank spaces are permitted.

I'm not sure of your exact requirement but one possible solution to improve 'readability' is to store it as an array.

{
  "testCases" :
  {
    "case.1" :
    {
      "scenario" : "this the case 1.",
      "result" : ["this is a very long line which is not easily readble.",
                  "so i would like to write it in multiple lines.",
                  "but, i do NOT require any new lines in the output."]
    }
  }
}

}

The join in back again whenever required with

result.join(" ")

Just adding another idea you could use a child selector to get immediate children

document.querySelectorAll(".parent > .child1");

should return all the immediate children with class .child1

You can use the (object) function to convert your array into an object.

$arr= [128=> ['status'=>
                 'Figure A. Facebook \'s horizontal scrollbars showing up on a 1024x768 screen resolution.'],
                  129=>['status'=>'The other day at work, I had some spare time']];

            $ArrToObject=(object)$arr;
            var_dump($ArrToObject);

The result will be an object that contains arrays:

object(stdClass)#1048 (2) { [128]=> array(1) {

["status"]=> string(87) "Figure A. Facebook 's horizontal scrollbars showing up on a 1024x768 screen resolution." }

[129]=> array(1) { ["status"]=> string(44) "The other day at work, I had some spare time" } }

jsonlite will import the JSON into a data frame. It can optionally flatten nested objects. Nested arrays will be data frames.

> library(jsonlite)
> winners <- fromJSON("winners.json", flatten=TRUE)
> colnames(winners)
[1] "winner" "votes" "startPrice" "lastVote.timestamp" "lastVote.user.name" "lastVote.user.user_id"
> winners[,c("winner","startPrice","lastVote.user.name")]
    winner startPrice lastVote.user.name
1 68694999          0              Lamur
> winners[,c("votes")]
[[1]]
                            ts user.name user.user_id
1 Thu Mar 25 03:13:01 UTC 2010     Lamur     68694999
2 Thu Mar 25 03:13:08 UTC 2010     Lamur     68694999

My user account did not have the permissions to alter the database and table, as suggested in this solution.

If, like me, you don't care about the character collation (you are using the '=' operator), you can apply the reverse fix. Run this before your SELECT:

SET collation_connection = 'latin1_swedish_ci';

When I started using json, I was confused and unable to figure it out for some time, but finally I got what I wanted
Here is the simple solution

import json
m = {'id': 2, 'name': 'hussain'}
n = json.dumps(m)
o = json.loads(n)
print(o['id'], o['name'])

Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        Double d = scan.nextDouble();


        String newStr = "";
        Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
        while( charScanner.hasNext() ) { 
            String  c = charScanner.next();

            if (c.equalsIgnoreCase("\r")) {
                break;
            }
            else {
                newStr += c;    
            }
        }

        System.out.println("String: " + newStr);
        System.out.println("Int: " + i);
        System.out.println("Double: " + d);

This code works fine

Now there are a lot of cloud providers , providing solutions like MBaaS (Mobile Backend as a Service). Some only give access to cloud database, some will do the user management for you, some let you place code around cloud database and there are facilities of access control, push notifications, analytics, integrated image and file hosting etc.

Here are some providers which have a "free-tier" (may change in future):

1. Firebase (Google) - https://firebase.google.com/
2. AWS Mobile (Amazon) - https://aws.amazon.com/mobile/
3. Azure Mobile (Microsoft) - https://azure.microsoft.com/en-in/services/app-service/mobile/
4. MongoDB Realm (MongoDB) - https://www.mongodb.com/realm
5. Back4app (Popular) - https://www.back4app.com/

Open source solutions:

1. Parse - http://parseplatform.org/
2. Apache User Grid - https://usergrid.apache.org/
3. SupaBase (under development) - https://supabase.io/

Even better with StringBuilder using insert() in front of the decimal string under construction, without calling reverse(),

static String toBinary(int n) {
    if (n == 0) {
        return "0";
    }

    StringBuilder bldr = new StringBuilder();
    while (n > 0) {
        bldr = bldr.insert(0, n % 2);
        n = n / 2;
    }

    return bldr.toString();
}

For anyone experiencing this on windows after an update

What happened was that Windows Defender made some changes. Possibly cause running data extraction scripts, but python.exe got reduced to 0kb for that project. Copying the python.exe from another project and replacing it solved for now.

Here is the best way to do it in compilation time. I have used the arg_var count answer from here.

#define PP_NARG(...) \
     PP_NARG_(__VA_ARGS__,PP_RSEQ_N())
#define PP_NARG_(...) \
         PP_ARG_N(__VA_ARGS__)

#define PP_ARG_N( \

#define TypedEnum(Name, ...)                                      \
struct Name {                                                     \
    enum {                                                        \
        __VA_ARGS__                                               \
    };                                                            \
    static const uint32_t Name##_MAX = PP_NARG(__VA_ARGS__);      \
}

#define Enum(Name, ...) TypedEnum(Name, __VA_ARGS__)

To declare an enum:

Enum(TestEnum, 
Enum_1= 0,
Enum_2= 1,
Enum_3= 2,
Enum_4= 4,
Enum_5= 8,
Enum_6= 16,
Enum_7= 32);

the max will be available here:

int array [TestEnum::TestEnum_MAX];
for(uint32_t fIdx = 0; fIdx < TestEnum::TestEnum_MAX; fIdx++)
{
     array [fIdx] = 0;
}

You have a couple of options:

• You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)
• You can add them in your global PATH environment variable
• You can start Visual Studio using a batch file as I described here and manipulate the path in that one
• You can copy the DLLs into the executable file's directory :-)

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

In the answers here, up to now, we find two ways of changing the JRE locale setting:

• Programatically, using Locale.setDefault() (which, in my case, was the solution, since I didn't want to require any action of the user):

  Locale.setDefault(new Locale("pt", "BR"));
  

• Via arguments to the JVM:

  java -jar anApp.jar -Duser.language=pt-BR
  

But, just as reference, I want to note that, on Windows, there is one more way of changing the locale used by the JRE, as documented here: changing the system-wide language.

Note: You must be logged in with an account that has Administrative Privileges.

1. Click Start > Control Panel.

2. Windows 7 and Vista: Click Clock, Language and Region > Region and Language.

   Windows XP: Double click the Regional and Language Options icon.

   The Regional and Language Options dialog box appears.

3. Windows 7: Click the Administrative tab.

   Windows XP and Vista: Click the Advanced tab.

   (If there is no Advanced tab, then you are not logged in with administrative privileges.)

4. Under the Language for non-Unicode programs section, select the desired language from the drop down menu.

5. Click OK.

   The system displays a dialog box asking whether to use existing files or to install from the operating system CD. Ensure that you have the CD ready.

6. Follow the guided instructions to install the files.

7. Restart the computer after the installation is complete.

Certainly on Linux the JRE also uses the system settings to determine which locale to use, but the instructions to set the system-wide language change from distro to distro.

The problem with system.gc, is that the JVM already automatically allocates time to the garbage collector based on memory usage.

However, if you are, for instance, working in a very memory limited condition, like a mobile device, System.gc allows you to manually allocate more time towards this garbage collection, but at the cost of cpu time (but, as you said, you aren't that concerned about performance issues of gc).

Best practice would probably be to only use it where you might be doing large amounts of deallocation (like flushing a large array).

All considered, since you are simply concerned about memory usage, feel free to call gc, or, better yet, see if it makes much of a memory difference in your case, and then decide.

total edge case here: I had this issue installing an Arch AUR PKGBUILD file manually. In my case I needed to delete the 'pkg', 'src' and 'node_modules' folders, then it built fine without this npm error.

I tried as you mentioned, but only first parameter is going through and rest all are appearing in the server as undefined. I am passing JSONWebToken as part of header.

.ajax({
    url: 'api/outletadd',
    type: 'post',
    data: { outletname:outletname , addressA:addressA , addressB:addressB, city:city , postcode:postcode , state:state , country:country , menuid:menuid },
    headers: {
        authorization: storedJWT
    },
    dataType: 'json',
    success: function (data){
        alert("Outlet Created");
    },
    error: function (data){
        alert("Outlet Creation Failed, please try again.");        
    }

    });

//but i cannot really get the id and assign it to an array that is not with in the scope?(or can I)

Yes, you can!

var IDs = [];
$("#mydiv").find("span").each(function(){ IDs.push(this.id); });

This is the beauty of closures.

Note that while you were on the right track, sighohwell and cletus both point out more reliable and concise ways of accomplishing this, taking advantage of attribute filters (to limit matched elements to those with IDs) and jQuery's built-in map() function:

var IDs = $("#mydiv span[id]")         // find spans with ID attribute
  .map(function() { return this.id; }) // convert to set of IDs
  .get(); // convert to instance of Array (optional)

vannilla Nodejs callback

function fileExists(path, cb){
  return fs.access(path, fs.constants.F_OK,(er, result)=> cb(!err && result)) //F_OK checks if file is visible, is default does no need to be specified.
}

the docs say you should use access() as a replacement for deprecated exists()

Nodejs with build in promise (node 7+)

function fileExists(path, cb){
  return new Promise((accept,deny) => 
    fs.access(path, fs.constants.F_OK,(er, result)=> cb(!err && result))
  );
}

Popular javascript framework

fs-extra

var fs = require('fs-extra')
await fs.pathExists(filepath)

As you see much simpler. And the advantage over promisify is that you have complete typings with this package (complete intellisense/typescript)! Most of the cases you will have already included this library because (+-10.000) other libraries depend on it.

Since C++11, you can copy arrays directly with std::array:

std::array<int,4> A = {10,20,30,40};
std::array<int,4> B = A; //copy array A into array B

Here is the documentation about std::array

Assuming there is a column named business:

SELECT Business, COUNT(*) FROM eventsTable GROUP BY Business
