"I actually tried to had a normal objective discusssion over pros and cons of 1., using framework over pure javascript and 2., jquery vs. others, since jQuery seems to be easiest to work with with quickest learning curve."

Using any framework because you don't want to actually learn the underlying language is absolutely wrong not only for JavaScript, but for any other programming language.

"Is there any reason (besides browser sniffing and personal "hate" against John Resig) why jQuery is wrong?"

Most of the hate agains it comes from the exaggerated fanboyism which pollutes forums with "use jQuery" as an answer for every single JavaScript question and the overuse which produces code in which simple statements such as declaring a variable are done through library calls.

Nevertheless, there are also some legit technical issues such as the shared guilt in producing illegible code and overhead. Of course those two are aggravated by the lack of developer proficiency rather than the library itself.

To attempt command line arguments directly is not possible.

One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).

This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html

so sudo systemctl restart myprog -v -- systemctl will think you're trying to set one of its flags, not myprog's flag.

sudo systemctl restart myprog someotheroption -- systemctl will restart myprog and the someotheroption service, if it exists.

zerkms told you the difference. If you like you can "convert" a string to an array of strings with length of 1.

If you want to send the string as a argument for example you can do like this:

var myString = "Test";

MethodThatRequiresStringArrayAsParameter( new[]{myString} );

I honestly can't see any other reason of doing the conversion than to satisty a method argument, but if it's another reason you will have to provide some information as to what you are trying to accomplish since there is probably a better solution.

You can do something like the following these days by referencing the "beforeSubmit" jquery form event. I'm disabling and enabling the submit button to avoid duplicate requests, submitting via ajax, returning a message that's a json array and displaying the information in a pNotify:

jQuery('body').on('beforeSubmit', "#formID", function() {
    $('.submitter').prop('disabled', true);
    var form = $('#formID');
    $.ajax({
        url    : form.attr('action'),
        type   : 'post',
        data   : form.serialize(),
        success: function (response)
        {
            response = jQuery.parseJSON(response);
            new PNotify({
                text: response.message,
                type: response.status,
                styling: 'bootstrap3',
                delay: 2000,
            });
            $('.submitter').prop('disabled', false);
        },
        error  : function ()
        {
            console.log('internal server error');
        }
    });
});

No, you do not need to check whether you’re already on the main thread. By dispatching the block to the main queue, you’re just scheduling the block to be executed serially on the main thread, which happens when the corresponding run loop is run.

If you already are on the main thread, the behaviour is the same: the block is scheduled, and executed when the run loop of the main thread is run.

For a range of Comparable I use the following :

Maybe try this:

ActiveRecord::Base.establish_connection(...)
ActiveRecord::Base.connection.execute(...)

If this is for a non-Rails project, I'd use String#index:

"foobar".index("foo") == 0  # => true

You mean you want to show a javascript alert when a button is clicked on a PHP generated page?

echo('<button type="button" onclick="alert(\'Alrt Text!\');">My Button</button>');

Would do that

For elementwise multiplication of matrix objects, you can use numpy.multiply:

import numpy as np
a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])
np.multiply(a,b)

Result

array([[ 5, 12],
       [21, 32]])

However, you should really use array instead of matrix. matrix objects have all sorts of horrible incompatibilities with regular ndarrays. With ndarrays, you can just use * for elementwise multiplication:

a * b

If you're on Python 3.5+, you don't even lose the ability to perform matrix multiplication with an operator, because @ does matrix multiplication now:

a @ b  # matrix multiplication

Modify your log4j.properties file accordingly:

log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog

Change the log levels for each logger depending to your needs.

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

The hidden character is probably BOM. The explanation to the problem and the solution can be found here, credits to James Schubert, based on an answer by James Brankin found here.

Though the previous answer does remove the hidden character, it also removes the whole first line. The more precise version would be:

string _byteOrderMarkUtf8 = Encoding.UTF8.GetString(Encoding.UTF8.GetPreamble());
if (xml.StartsWith(_byteOrderMarkUtf8))
{
    xml = xml.Remove(0, _byteOrderMarkUtf8.Length);
}

I encountered this problem when fetching an XSLT file from Azure blob and loading it into an XslCompiledTransform object. On my machine the file looked just fine, but after uploading it as a blob and fetching it back, the BOM character was added.

Response.Redirect() should be used when:

• we want to redirect the request to some plain HTML pages on our server or to some other web server
• we don't care about causing additional roundtrips to the server on each request
• we do not need to preserve Query String and Form Variables from the original request
• we want our users to be able to see the new redirected URL where he is redirected in his browser (and be able to bookmark it if its necessary)

Server.Transfer() should be used when:

• we want to transfer current page request to another .aspx page on the same server
• we want to preserve server resources and avoid the unnecessary roundtrips to the server
• we want to preserve Query String and Form Variables (optionally)
• we don't need to show the real URL where we redirected the request in the users Web Browser

Here's a tutorial about ordering objects:

• The Java Tutorials - Collections - Object Ordering

Although I will give some examples, I would recommend to read it anyway.

There are various way to sort an ArrayList. If you want to define a natural (default) ordering, then you need to let Contact implement Comparable. Assuming that you want to sort by default on name, then do (nullchecks omitted for simplicity):

public class Contact implements Comparable<Contact> {

    private String name;
    private String phone;
    private Address address;

    @Override
    public int compareTo(Contact other) {
        return name.compareTo(other.name);
    }

    // Add/generate getters/setters and other boilerplate.
}

so that you can just do

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

Collections.sort(contacts);

If you want to define an external controllable ordering (which overrides the natural ordering), then you need to create a Comparator:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Now sort by address instead of name (default).
Collections.sort(contacts, new Comparator<Contact>() {
    public int compare(Contact one, Contact other) {
        return one.getAddress().compareTo(other.getAddress());
    }
}); 

You can even define the Comparators in the Contact itself so that you can reuse them instead of recreating them everytime:

public class Contact {

    private String name;
    private String phone;
    private Address address;

    // ...

    public static Comparator<Contact> COMPARE_BY_PHONE = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.phone.compareTo(other.phone);
        }
    };

    public static Comparator<Contact> COMPARE_BY_ADDRESS = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.address.compareTo(other.address);
        }
    };

}

which can be used as follows:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Sort by address.
Collections.sort(contacts, Contact.COMPARE_BY_ADDRESS);

// Sort later by phone.
Collections.sort(contacts, Contact.COMPARE_BY_PHONE);

And to cream the top off, you could consider to use a generic javabean comparator:

public class BeanComparator implements Comparator<Object> {

    private String getter;

    public BeanComparator(String field) {
        this.getter = "get" + field.substring(0, 1).toUpperCase() + field.substring(1);
    }

    public int compare(Object o1, Object o2) {
        try {
            if (o1 != null && o2 != null) {
                o1 = o1.getClass().getMethod(getter, new Class[0]).invoke(o1, new Object[0]);
                o2 = o2.getClass().getMethod(getter, new Class[0]).invoke(o2, new Object[0]);
            }
        } catch (Exception e) {
            // If this exception occurs, then it is usually a fault of the developer.
            throw new RuntimeException("Cannot compare " + o1 + " with " + o2 + " on " + getter, e);
        }

        return (o1 == null) ? -1 : ((o2 == null) ? 1 : ((Comparable<Object>) o1).compareTo(o2));
    }

}

which you can use as follows:

// Sort on "phone" field of the Contact bean.
Collections.sort(contacts, new BeanComparator("phone"));

(as you see in the code, possibly null fields are already covered to avoid NPE's during sort)

Boost Test Library is a very good choice especially if you're already using Boost.

// TODO: Include your class to test here.
#define BOOST_TEST_MODULE MyTest
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE(MyTestCase)
{
    // To simplify this example test, let's suppose we'll test 'float'.
    // Some test are stupid, but all should pass.
    float x = 9.5f;

    BOOST_CHECK(x != 0.0f);
    BOOST_CHECK_EQUAL((int)x, 9);
    BOOST_CHECK_CLOSE(x, 9.5f, 0.0001f); // Checks differ no more then 0.0001%
}

It supports:

• Automatic or manual tests registration
• Many assertions
• Automatic comparison of collections
• Various output formats (including XML)
• Fixtures / Templates...

PS: I wrote an article about it that may help you getting started: C++ Unit Testing Framework: A Boost Test Tutorial

An instance method applies to an instance of the class (i.e. an object) whereas a class method applies to the class itself.

In C# a class method is marked static. Methods and properties not marked static are instance methods.

class Foo {
  public static void ClassMethod() { ... }
  public void InstanceMethod() { ... }
}

I've recently found even more interesting way to create any ValueNode or ContainerNode (Jackson v2.3).

ObjectNode node = JsonNodeFactory.instance.objectNode();

Bower uses semver syntax, but here are a few quick examples:

You can install a specific version:

$ bower install jquery#1.11.1

You can use ~ to specify 'any version that starts with this':

$ bower install jquery#~1.11

You can specify multiple version requirements together:

$ bower install "jquery#<2.0 >1.10"

If you select the log entry to which you want to revert to then you can click on "Reset to this commit". Only use this option if you didn't push the reverse commit changes. If you're worried about losing the changes then you can use the soft mode which will leave a set of uncommitted changes (what you just changed). Using the mixed resets the working copy but keeps those changes, and a hard will just get rid of the changes entirely. Here's some screenshots:

SWIFT 3/4

Solution for CustomCell.selectionStyle = .none if you set some else style you saw "mixed" background color with gray or blue.

And don't forget! func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) didn't call when CustomCell.selectionStyle = .none.

extension MenuView: UITableViewDelegate {
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let cellType = menuItems[indexPath.row]
        let selectedCell = tableView.cellForRow(at: indexPath)!
            selectedCell.contentView.backgroundColor = cellType == .none ? .clear : AppDelegate.statusbar?.backgroundColor?.withAlphaComponent(0.15)

        menuItemDidTap?(menuItems[indexPath.row])

        UIView.animate(withDuration: 0.15) {
            selectedCell.contentView.backgroundColor = .clear
        }
    }
}

You can do that with a single statement and a subquery in nearly all relational databases.

INSERT INTO targetTable(field1) 
SELECT field1
FROM myTable
WHERE NOT(field1 IN (SELECT field1 FROM targetTable))

Certain relational databases have improved syntax for the above, since what you describe is a fairly common task. SQL Server has a MERGE syntax with all kinds of options, and MySQL has optional INSERT OR IGNORE syntax.

Edit: SmallSQL's documentation is fairly sparse as to which parts of the SQL standard it implements. It may not implement subqueries, and as such you may be unable to follow the advice above, or anywhere else, if you need to stick with SmallSQL.

if you use entity framework and you want to make the only int acceptable then you can use this in linq query you can try this

var items = from c in contacts
        select new ListItem
        {
            Value = (int)ContractId 
            Text = c.Name
        };

it will work because using (int) will cast your value to the int so you don't need any conversion for string to int and you get the result you want.

this worked for me in my project i think it would be helpful for you

In Chart.Js 2.8.0, the configuration for custom tooltips can be found here: https://www.chartjs.org/docs/latest/configuration/tooltip.html#label-callback (Thanks to @prokaktus)

If you want to e.g. show some values with a prefix or postfix (In the example, the script adds a unit of kWh to the values in the chart), you could do this like:

options: {
  rotation: 1 * Math.PI,
  circumference: 1 * Math.PI,
  tooltips: {
    callbacks: {
      label: function(tooltipItem, data) {
        console.log(data);
        console.log(tooltipItem);

        var label = data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index] || '';

        if (label) {
          label += ' kWh';
        }

        return label;
      }
    }
  }
}

An example fiddle is here, too: https://jsfiddle.net/y3petw58/1/

This for the Api you could use

 const express        = require('express');
 const bodyParser     = require('body-parser');
 const app = express();
 var multer = require('multer');
 const port = 8000;
 app.use(bodyParser.json());
 app.use(bodyParser.urlencoded({ extended: true }));

 app.listen(port, ()=>{
 console.log('We are live on' + port);
 });

 var upload = multer({dest:'./upload/'});

 app.post('/post', upload.single('file'), function(req, res) {
  console.log(req.file);
 res.send("file saved on server");
 });

This also works fine used on Postman but the file doesn't comes with .jpg extension any Advice? As commented below

This is the default feature of multer if uploads file with no extension, however, provides you the the file object, using which you can update the extension of the file.

var filename = req.file.filename; 
var mimetype = req.file.mimetype; 
mimetype = mimetype.split("/"); 
var filetype = mimetype[1]; 
var old_file = configUploading.settings.rootPathTmp+filename; 
var new_file = configUploading.settings.rootPathTmp+filename+'.'+filetype; 
rname(old_file,new_file);

For ENTER key, why not use (keyup.enter):

@Component({
  selector: 'key-up3',
  template: `
    <input #box (keyup.enter)="values=box.value">
    <p>{{values}}</p>
  `
})
export class KeyUpComponent_v3 {
  values = '';
}

You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.

I found out that with MySQL probably the correct query is the following:

SELECT SUBSTRING( FROM_UNIXTIME( CEILING( timestamp /300 ) *300,  
                                 '%Y-%m-%d %H:%i:%S' ) , 1, 19 ) AS ts_CEILING,
SUM(value)
FROM group_interval
GROUP BY SUBSTRING( FROM_UNIXTIME( CEILING( timestamp /300 ) *300,  
                                   '%Y-%m-%d %H:%i:%S' ) , 1, 19 )
ORDER BY SUBSTRING( FROM_UNIXTIME( CEILING( timestamp /300 ) *300,  
                                   '%Y-%m-%d %H:%i:%S' ) , 1, 19 ) DESC

Let me know what you think.

Use -d (full list of file tests)

if (-d "cgi-bin") {
    # directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
    # cgi-bin exists but is not a directory
}
else {
    # nothing called cgi-bin exists
}

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.

use Contains of jquery Contains like this

if ($('.type:contains("> <")').length > 0)
{
 //do stuffs to change 
}

.offset() will return the offset position of an element as a simple object, eg:

var position = $(element).offset(); // position = { left: 42, top: 567 }

You can use this return value to position other elements at the same spot:

$(anotherElement).css(position)

Regular expression is your answer.

$str = preg_replace('/[^a-z\d ]/i', '', $str);

• The i stands for case insensitive.
• ^ means, does not start with.
• \d matches any digit.
• a-z matches all characters between a and z. Because of the i parameter you don't have to specify a-z and A-Z.
• After \d there is a space, so spaces are allowed in this regex.

Error messages don't get any clearer than this:

"Scripts may close only the windows that were opened by it."

If your script did not initiate opening the window (with something like window.open), then the script in that window is not allowed to close it. Its a security to prevent a website taking control of your browser and closing windows.

You can do this using -T option in cp.
See Man page for cp.

-T, --no-target-directory
    treat DEST as a normal file

So as per your example, following is the file structure.

$ tree test
test
|-- bar
|   |-- a
|   `-- b
`-- foo
    |-- a
    `-- b
2 directories, 4 files

You can see the clear difference when you use -v for Verbose.
When you use just -R option.

$ cp -Rv foo/ bar/
`foo/' -> `bar/foo'
`foo/b' -> `bar/foo/b'
`foo/a' -> `bar/foo/a'
 $ tree
 |-- bar
 |   |-- a
 |   |-- b
 |   `-- foo
 |       |-- a
 |       `-- b
 `-- foo
     |-- a
     `-- b
3 directories, 6 files

When you use the option -T it overwrites the contents, treating the destination like a normal file and not directory.

$ cp -TRv foo/ bar/
`foo/b' -> `bar/b'
`foo/a' -> `bar/a'

$ tree
|-- bar
|   |-- a
|   `-- b
`-- foo
    |-- a
    `-- b
2 directories, 4 files

This should solve your problem.

There are many ways you can find the difference between dates & times. One of the simplest ways that I know of would be:

      Calendar calendar1 = Calendar.getInstance();
      Calendar calendar2 = Calendar.getInstance();
      calendar1.set(2012, 04, 02);
      calendar2.set(2012, 04, 04);
      long milsecs1= calendar1.getTimeInMillis();
      long milsecs2 = calendar2.getTimeInMillis();
      long diff = milsecs2 - milsecs1;
      long dsecs = diff / 1000;
      long dminutes = diff / (60 * 1000);
      long dhours = diff / (60 * 60 * 1000);
      long ddays = diff / (24 * 60 * 60 * 1000);

      System.out.println("Your Day Difference="+ddays);

The print statement is just an example - you can format it, the way you like.

I've seen many answers but they seem confusing to me. Can't we just simply use Type Casting.

For ex:-

int s;
char i= '2';
s = (int) i;

public Point2D(Point2D point) : this(point.X, point.Y) { }

You could just partition the tables no?

"Partitioned Table and Index Strategies Using SQL Server 2008 When a database table grows in size to the hundreds of gigabytes or more, it can become more difficult to load new data, remove old data, and maintain indexes. Just the sheer size of the table causes such operations to take much longer. Even the data that must be loaded or removed can be very sizable, making INSERT and DELETE operations on the table impractical. The Microsoft SQL Server 2008 database software provides table partitioning to make such operations more manageable."

check the official example. X,Y and Z are indeed 2d arrays, numpy.meshgrid() is a simple way to get 2d x,y mesh out of 1d x and y values.

http://matplotlib.sourceforge.net/mpl_examples/mplot3d/surface3d_demo.py

here's pythonic way to convert your 3-tuples to 3 1d arrays.

data = [(1,2,3), (10,20,30), (11, 22, 33), (110, 220, 330)]
X,Y,Z = zip(*data)
In [7]: X
Out[7]: (1, 10, 11, 110)
In [8]: Y
Out[8]: (2, 20, 22, 220)
In [9]: Z
Out[9]: (3, 30, 33, 330)

Here's mtaplotlib delaunay triangulation (interpolation), it converts 1d x,y,z into something compliant (?):

http://matplotlib.sourceforge.net/api/mlab_api.html#matplotlib.mlab.griddata

You have to convert the "DateTime" to a "Date". Then you can easier select just one for the given date no matter the time for that date.

GRANT USAGE ON SCHEMA schema_name TO user;

Add an = at the beginning. That makes it a function rather than an entry.

I have a solution below and its works for me:

app.controller('LoginController', ['$http', '$scope', function ($scope, $http) {
$scope.login = function (credentials) {
$http({
        method: 'jsonp',
        url: 'http://mywebservice',
        params: {
            format: 'jsonp',
            callback: 'JSON_CALLBACK'
        }
    }).then(function (response) {
        alert(response.data);
    });
  }
}]);

in 'http://mywebservice' there must be need a callback parameter which return JSON_CALLBACK with data.
There is a sample example below which works perfect

$scope.url = "https://angularjs.org/greet.php";
    $http({
        method: 'jsonp',
        url: $scope.url,
        params: {
            format: 'jsonp',
            name: 'Super Hero',
            callback: 'JSON_CALLBACK'
        }
    }).then(function (response) {
        alert(response.data);
    });

example output:

{"name":"Super Hero","salutation":"Apa khabar","greeting":"Apa khabar Super Hero!"}

You could try using chruby? chruby does not rely on shims, instead it only modifies PATH, GEM_HOME, GEM_PATH.

Use apt to uninstall and remove all MySQL packages:

$ sudo apt-get remove --purge mysql-server mysql-client mysql-common -y
$ sudo apt-get autoremove -y
$ sudo apt-get autoclean

Remove the MySQL folder:

 $ rm -rf /etc/mysql

Delete all MySQL files on your server:

$ sudo find / -iname 'mysql*' -exec rm -rf {} \;

Your system should no longer contain default MySQL related files.

The objectsAreSame function mentioned in @JasonBunting's answer works fine for me. However, there's a little problem: If x[propertyName] and y[propertyName] are objects (typeof x[propertyName] == 'object'), you'll need to call the function recursively in order to compare them.

1. TIMESTAMP is four bytes vs eight bytes for DATETIME.

2. Timestamps are also lighter on the database and indexed faster.

3. The DATETIME type is used when you need values that contain both date and time information. MySQL retrieves and displays DATETIME values in ‘YYYY-MM-DD HH:MM:SS’ format. The supported range is ’1000-01-01 00:00:00' to ’9999-12-31 23:59:59'.

The TIMESTAMP data type has a range of ’1970-01-01 00:00:01' UTC to ’2038-01-09 03:14:07' UTC. It has varying properties, depending on the MySQL version and the SQL mode the server is running in.

4. DATETIME is constant while TIMESTAMP is effected by the time_zone setting.

If you haven't created migrations, there are 2 options

1.create the database and tables from application Main:

var context = services.GetRequiredService<YourRepository>();
context.Database.EnsureCreated();

2.create the tables if the database already exists:

var context = services.GetRequiredService<YourRepository>();
context.Database.EnsureCreated();
RelationalDatabaseCreator databaseCreator =
(RelationalDatabaseCreator)context.Database.GetService<IDatabaseCreator>();
databaseCreator.CreateTables();

Thanks to Bubi's answer

wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[contains(text(), 'YourTextHere')]")));
assertNotNull(driver.findElement(By.xpath("//*[contains(text(), 'YourTextHere')]")));
String yourButtonName = driver.findElement(By.xpath("//*[contains(text(), 'YourTextHere')]")).getAttribute("innerText");

To piggyback on rkj's answer, to avoid endless prompts (and force the command recursively), enter the following into the command line, within the project folder:

$ rm -rf .git

Or to delete .gitignore and .gitmodules if any (via @aragaer):

$ rm -rf .git*

Then from the same ex-repository folder, to see if hidden folder .git is still there:

$ ls -lah

If it's not, then congratulations, you've deleted your local git repo, but not a remote one if you had it. You can delete GitHub repo on their site (github.com).

To view hidden folders in Finder (Mac OS X) execute these two commands in your terminal window:

defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder

In case dingbats/icon fonts are an option, you can use them instead of images.

The following uses a combination of

• an icon font (e.g. Font Awesome),
• character encodings in HTML (e.g. &#xf090)
• the Unicode code point of the icon you want to use (e.g. &#xf090 for the sign in logo),
• CSS:

In HTML:

<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.no-icons.min.css" rel="stylesheet">
<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

<form name="signin" action="#" method="POST">
    <input type="text" name="text-input" placeholder="&#xf183; your username" class="stylish"/><br/>
    <input type="submit" value="&#xf090; sign in" class="stylish"/>
</form>

In CSS:

.stylish {
    font-family: georgia, FontAwesome;
}

jsFiddle

Notice the font-family specification: all characters/code points will use georgia, falling back to FontAwesome for any code points georgia doesn't provide characters for. georgia doesn't provide any characters in the private use range, exactly where FontAwesome has placed its icons.

- First we must know that the diff bet static and non static methods 
is differ from static and non static variables : 

- this code explain static method - non static method and what is the diff

If you absolutely must use HTML to give your text color, you have to use the (deprecated) <font>-tag:

<h2><font color="#006699">Process Report</font></h2>

But otherwise, I strongly recommend you to do as rekire said: use CSS.

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

A little addition to what's written up there:

First, make sure your destructor is also pure virtual

Second, you may want to inherit virtually (rather than normally) when you do implement, just for good measures.

This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.

This can happen if the other side crashes and then comes back up or if it calls close() on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.

It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.

Using a list comprehension:

from datetime import date, timedelta

d1 = date(2008,8,15)
d2 = date(2008,9,15)

# this will give you a list containing all of the dates
dd = [d1 + timedelta(days=x) for x in range((d2-d1).days + 1)]

for d in dd:
    print d

# you can't join dates, so if you want to use join, you need to
# cast to a string in the list comprehension:
ddd = [str(d1 + timedelta(days=x)) for x in range((d2-d1).days + 1)]
# now you can join
print "\n".join(ddd)

Here is one way to test which YAML implementation the user has selected on the virtualenv (or the system) and then define load_yaml_file appropriately:

load_yaml_file = None

if not load_yaml_file:
    try:

        load_yaml_file = lambda fn: yaml.load(open(fn))
    except:

        def load_yaml_file(fn):
            ruby = "puts YAML.load_file('%s').to_json" % fn
            j = commands.getstatusoutput('ruby -ryaml -rjson -e "%s"' % ruby)
            return json.loads(j[1])

if not load_yaml_file:
    import os, sys

You can simply include a Javascript file in your HTML that declares your JSON object as a variable. Then you can access your JSON data from your global Javascript scope using data.employees, for example.

index.html:

<html>
<head>
</head>
<body>
  <script src="data.js"></script>
</body>
</html>

data.js:

var data = {
  "start": {
    "count": "5",
    "title": "start",
    "priorities": [{
      "txt": "Work"
    }, {
      "txt": "Time Sense"
    }, {
      "txt": "Dicipline"
    }, {
      "txt": "Confidence"
    }, {
      "txt": "CrossFunctional"
    }]
  }
}

Use the sed delete command with a range address. For example:

sed 1,100d file.txt # Print file.txt omitting lines 1-100.

Alternatively, if you want to only print a known range, use the print command with the -n flag:

sed -n 201,300p file.txt # Print lines 201-300 from file.txt

This solution should work reliably on all Unix systems, regardless of the presence of GNU utilities.

Visual Studio Community 2015 suffices to build extensions for Python 3.5. It's free but a 6 GB download (overkill). On my computer it installed vcvarsall at C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat

For Python 3.4 you'd need Visual Studio 2010. I don't think there's any free edition. See https://matthew-brett.github.io/pydagogue/python_msvc.html

You can use the step attribute to the input type number:

<input type="number" id="totalAmt" step="0.1"></input>

step="any" will allow any decimal.
step="1" will allow no decimal.
step="0.5" will allow 0.5; 1; 1.5; ...
step="0.1" will allow 0.1; 0.2; 0.3; 0.4; ...

Initializing a vector having struct, class or Union can be done this way

std::vector<SomeStruct> someStructVect(length);
memset(someStructVect.data(), 0, sizeof(SomeStruct)*length);

If a method (instance or static) only references variables scoped within that method then it is thread safe because each thread has its own stack:

In this instance, multiple threads could call ThreadSafeMethod concurrently without issue.

public class Thing
{
    public int ThreadSafeMethod(string parameter1)
    {
        int number; // each thread will have its own variable for number.
        number = parameter1.Length;
        return number;
    }
}

This is also true if the method calls other class method which only reference locally scoped variables:

public class Thing
{
    public int ThreadSafeMethod(string parameter1)
    {
        int number;
        number = this.GetLength(parameter1);
        return number;
    }

    private int GetLength(string value)
    {
        int length = value.Length;
        return length;
    }
}

If a method accesses any (object state) properties or fields (instance or static) then you need to use locks to ensure that the values are not modified by a different thread.

public class Thing
{
    private string someValue; // all threads will read and write to this same field value

    public int NonThreadSafeMethod(string parameter1)
    {
        this.someValue = parameter1;

        int number;

        // Since access to someValue is not synchronised by the class, a separate thread
        // could have changed its value between this thread setting its value at the start 
        // of the method and this line reading its value.
        number = this.someValue.Length;
        return number;
    }
}

You should be aware that any parameters passed in to the method which are not either a struct or immutable could be mutated by another thread outside the scope of the method.

To ensure proper concurrency you need to use locking.

for further information see lock statement C# reference and ReadWriterLockSlim.

lock is mostly useful for providing one at a time functionality,
ReadWriterLockSlim is useful if you need multiple readers and single writers.

The copy command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.

Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).

I tried a variation of your command as follows in SQL*Plus (with no errors):

copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;

After I executed the above statement, I also truncate the new_emp table and executed this command:

copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;

With SQL Developer, you could do the following to perform a similar approach to copying objects:

1. On the tool bar, select Tools>Database copy.

2. Identify source and destination connections with the copy options you would like.

3. For object type, select table(s).

4. Specify the specific table(s) (e.g. table1).

The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).

The below silent .bat file code prevents the need to have two bat files (using "goto" and ":").

It does it all in the same .bat file. Tested and confirmed working in Windows 10

Make sure you replace "C:\pathToFile\ThisBatFile.bat " with the path to this same .bat file! Keep the space after ".bat".

@echo off
if [%1]==[] (
    goto PreSilentCall
) else (
    goto SilentCall
)

:PreSilentCall
REM Insert code here you want to have happen BEFORE this same .bat file is called silently
REM such as setting paths like the below two lines

set WorkingDirWithSlash=%~dp0
set WorkingDirectory=%WorkingDirWithSlash:~0,-1%

REM below code will run this same file silently, but will go to the SilentCall section
cd C:\Windows\System32
if exist C:\Windows\Temp\invis.vbs ( del C:\Windows\Temp\invis.vbs /f /q )
echo CreateObject("Wscript.Shell").Run "C:\pathToFile\ThisBatFile.bat " ^& WScript.Arguments(0), 0, False > C:\Windows\Temp\invis.vbs
wscript.exe C:\Windows\Temp\invis.vbs Initialized
if %ERRORLEVEL%==0 (
    echo Successfully started SilentCall code. This command prompt can now be exited.
    goto Exit
)

REM since it will be running silently. You can add a greater than symbol at the end of

REM of debugging this section of code.


:Exit

If your .bat file needs more than just the "Initialized" argument (which tells the bat file to go to :SilentCall section), add "^& WScript.Arguments(1)," , "^& WScript.Arguments(2)," ,etc. depending on the number of arguments, then edit the line where wscript.exe is called:

"wscript.exe C:\Windows\Temp\invis.vbs Initialized BatFileArgOne BatFileArgTwo"

The easiest way to match both

^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$

and

^[0-9]{3}-[0-9]{3}-[0-9]{4}$

is to use alternation ((...|...)): specify them as two mostly-separate options:

^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$

By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234, not (123)123-1234. So you might want to write:

^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$

(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)

With LESS the actual mixin is in vendor-prefixes.less

.placeholder(@color: @input-color-placeholder) {
...
}

This mixin is called in forms.less on line 133:

.placeholder();

Your solution in LESS is:

.placeholder(#fff);

Imho the best way to go. Just use Winless or a composer compiler like Gulp/Grunt works, too and even better/faster.

if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):

count before dedupe:

df.count()

do the de-dupe (convert the column you are de-duping to string type):

from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))

df.drop_duplicates(subset=['colName']).count()

can use a sorted groupby to check to see that duplicates have been removed:

df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)

Select * from people p, address a where  p.id = a.person_id and a.zip='97229';

Or you must TRY using JOIN which is a more efficient and better way to do this as Gordon Linoff in the comments below also says that you need to learn this.

SELECT p.*, a.street, a.city FROM persons AS p
JOIN address AS a ON p.id = a.person_id
WHERE a.zip = '97299';

Here p.* means it will show all the columns of PERSONS table.

I had the same error

[Vue warn]: Unknown custom element: - did you register the component correctly? For recursive components, make sure to provide the "name" option.

however, I totally forgot to run npm install && npm run dev to compiling the js files.

maybe this helps newbies like me.

Well, the way you're timing things looks pretty nasty to me. It would be much more sensible to just time the whole loop:

var stopwatch = Stopwatch.StartNew();
for (int i = 1; i < 100000000; i++)
{
    Fibo(100);
}
stopwatch.Stop();
Console.WriteLine("Elapsed time: {0}", stopwatch.Elapsed);

That way you're not at the mercy of tiny timings, floating point arithmetic and accumulated error.

Having made that change, see whether the "non-catch" version is still slower than the "catch" version.

EDIT: Okay, I've tried it myself - and I'm seeing the same result. Very odd. I wondered whether the try/catch was disabling some bad inlining, but using [MethodImpl(MethodImplOptions.NoInlining)] instead didn't help...

Basically you'll need to look at the optimized JITted code under cordbg, I suspect...

EDIT: A few more bits of information:

• Putting the try/catch around just the n++; line still improves performance, but not by as much as putting it around the whole block
• If you catch a specific exception (ArgumentException in my tests) it's still fast
• If you print the exception in the catch block it's still fast
• If you rethrow the exception in the catch block it's slow again
• If you use a finally block instead of a catch block it's slow again
• If you use a finally block as well as a catch block, it's fast

Weird...

EDIT: Okay, we have disassembly...

This is using the C# 2 compiler and .NET 2 (32-bit) CLR, disassembling with mdbg (as I don't have cordbg on my machine). I still see the same performance effects, even under the debugger. The fast version uses a try block around everything between the variable declarations and the return statement, with just a catch{} handler. Obviously the slow version is the same except without the try/catch. The calling code (i.e. Main) is the same in both cases, and has the same assembly representation (so it's not an inlining issue).

In each case the * shows where the debugger entered in a simple "step-into".

EDIT: Okay, I've now looked through the code and I think I can see how each version works... and I believe the slower version is slower because it uses fewer registers and more stack space. For small values of n that's possibly faster - but when the loop takes up the bulk of the time, it's slower.

Possibly the try/catch block forces more registers to be saved and restored, so the JIT uses those for the loop as well... which happens to improve the performance overall. It's not clear whether it's a reasonable decision for the JIT to not use as many registers in the "normal" code.

EDIT: Just tried this on my x64 machine. The x64 CLR is much faster (about 3-4 times faster) than the x86 CLR on this code, and under x64 the try/catch block doesn't make a noticeable difference.

select a.empno,a.ename,a.job,a.mgr,B.empno,B.ename as MGR_name, B.job as MGR_JOB from 
    emp a, emp B where a.mgr=B.empno ;

I find it important to note that python 3 defines the opening modes differently to the answers here that were correct for Python 2.

The Pyhton 3 opening modes are:

'r' open for reading (default)
'w' open for writing, truncating the file first
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
----
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newlines mode (for backwards compatibility; should not be used in new code)

The modes r, w, x, a are combined with the mode modifiers b or t. + is optionally added, U should be avoided.

As I found out the hard way, it is a good idea to always specify t when opening a file in text mode since r is an alias for rt in the standard open() function but an alias for rb in the open() functions of all compression modules (when e.g. reading a *.bz2 file).

Thus the modes for opening a file should be:

rt / wt / xt / at for reading / writing / creating / appending to a file in text mode and

rb / wb / xb / ab for reading / writing / creating / appending to a file in binary mode.

Use + as before.

In Bootstrap 4 there is the utility class border-right which you can use.

So for example you can do:

<div class="row">
  <div class="col-6 border-right"></div>
  <div class="col-6"></div>
</div>

This worked for me

getActionBar().setDisplayShowHomeEnabled(false);

For laravel 5.* try these.

return redirect()->intended('/');

or

return Redirect::intended('/');

to leave the file in the repo but ignore future changes to it:

git update-index --assume-unchanged <file>

and to undo this:

git update-index --no-assume-unchanged <file>

to find out which files have been set this way:

git ls-files -v|grep '^h'

I've always used this syntax, which yields more predictable results than using !=.

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')" />

I had a similar issue when not using inline for my global function that was included in two places.

Nothing above made it work for me. The thing for me is that I was testing a subscription and i forgot SkuType.SUBS, changing it to INAPP for the reserved google test product fixed it.

I deal with the same problem (Jenkins multibranch pipeline) - having only commit information and trying to find a branch name where this commit originally came from. It must work for remote branches, local copies are not available.

This is what I work with:

git rev-parse HEAD | xargs git name-rev

Optionally you can strip the output:

git rev-parse HEAD | xargs git name-rev | cut -d' ' -f2 | sed 's/remotes\/origin\///g'

I would rewrite your dequeue function as:

std::string FileQueue::dequeue(const std::chrono::milliseconds& timeout)
{
    std::unique_lock<std::mutex> lock(qMutex);
    while(q.empty()) {
        if (populatedNotifier.wait_for(lock, timeout) == std::cv_status::timeout ) 
           return std::string();
    }
    std::string ret = q.front();
    q.pop();
    return ret;
}

It is shorter and does not have duplicate code like your did. Only issue it may wait longer that timeout. To prevent that you would need to remember start time before loop, check for timeout and adjust wait time accordingly. Or specify absolute time on wait condition.

Try this.

public function getDownload()
{
    //PDF file is stored under project/public/download/info.pdf
    $file= public_path(). "/download/info.pdf";

    $headers = array(
              'Content-Type: application/pdf',
            );

    return Response::download($file, 'filename.pdf', $headers);
}

"./download/info.pdf"will not work as you have to give full physical path.

Update 20/05/2016

Laravel 5, 5.1, 5.2 or 5.* users can use the following method instead of Response facade. However, my previous answer will work for both Laravel 4 or 5. (the $header array structure change to associative array =>- the colon after 'Content-Type' was deleted - if we don't do those changes then headers will be added in wrong way: the name of header wil be number started from 0,1,...)

$headers = [
              'Content-Type' => 'application/pdf',
           ];

return response()->download($file, 'filename.pdf', $headers);

For test navegation on Express:

const request = require('supertest');
const server = require('../bin/www');

describe('navegation', () => {
    it('login page', function(done) {
        this.timeout(4000);
        const timeOut = setTimeout(done, 3500);

        request(server)
            .get('/login')
            .expect(200)
            .then(res => {
                res.text.should.include('Login');
                clearTimeout(timeOut);
                done();
            })
            .catch(err => {
                console.log(this.test.fullTitle(), err);
                clearTimeout(timeOut);
                done(err);
            });
    });
});

In the example the test time is 4000 (4s).

Note: setTimeout(done, 3500) is minor for than done is called within the time of the test but clearTimeout(timeOut) it avoid than used all these time.

There isn't much else to add other than what the docs say. If you want to dump the JSON into a file/socket or whatever, then you should go with dump(). If you only need it as a string (for printing, parsing or whatever) then use dumps() (dump string)

As mentioned by Antti Haapala in this answer, there are some minor differences on the ensure_ascii behaviour. This is mostly due to how the underlying write() function works, being that it operates on chunks rather than the whole string. Check his answer for more details on that.

json.dump()

Serialize obj as a JSON formatted stream to fp (a .write()-supporting file-like object

If ensure_ascii is False, some chunks written to fp may be unicode instances

json.dumps()

Serialize obj to a JSON formatted str

If ensure_ascii is False, the result may contain non-ASCII characters and the return value may be a unicode instance

This,

public enum MySingleton {
  INSTANCE;   
}

has an implicit empty constructor. Make it explicit instead,

public enum MySingleton {
    INSTANCE;
    private MySingleton() {
        System.out.println("Here");
    }
}

If you then added another class with a main() method like

public static void main(String[] args) {
    System.out.println(MySingleton.INSTANCE);
}

You would see

Here
INSTANCE

enum fields are compile time constants, but they are instances of their enum type. And, they're constructed when the enum type is referenced for the first time.

Please use the attributes from the System.Web.Http namespace on your WebAPI actions:

    [System.Web.Http.AcceptVerbs("GET", "POST")]
    [System.Web.Http.HttpGet]
    public string Auth(string username, string password)
    {...}

The reason why it doesn't work is because you were using the attributes that are from the MVC namespace System.Web.Mvc. The classes in the System.Web.Http namespace are for WebAPI.

100% Working!

export EMAIL="[email protected]" && mutt -e "my_hdr Content-Type: text/html" -s "Test Mail" "[email protected]" < body_html.html

File: body_html.html

<HTML>
<HEAD> Test Mail </HEAD>

A late answer, but here is an alternative to the SCOPE_IDENTITY() answers that we ended up using: OUTPUT INSERTED

Return only ID of inserted object:

It allows you to get all or some attributes of the inserted row:

string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
                        OUTPUT INSERTED.[Id]
                        VALUES(@Username, @Phone, @Email);";

int newUserId = conn.QuerySingle<int>(
                                insertUserSql,
                                new
                                {
                                    Username = "lorem ipsum",
                                    Phone = "555-123",
                                    Email = "lorem ipsum"
                                },
                                tran);

Return inserted object with ID:

If you wanted you could get Phone and Email or even the whole inserted row:

string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
                        OUTPUT INSERTED.*
                        VALUES(@Username, @Phone, @Email);";

User newUser = conn.QuerySingle<User>(
                                insertUserSql,
                                new
                                {
                                    Username = "lorem ipsum",
                                    Phone = "555-123",
                                    Email = "lorem ipsum"
                                },
                                tran);

Also, with this you can return data of deleted or updated rows. Just be careful if you are using triggers because (from link mentioned before):

Columns returned from OUTPUT reflect the data as it is after the INSERT, UPDATE, or DELETE statement has completed but before triggers are executed.

For INSTEAD OF triggers, the returned results are generated as if the INSERT, UPDATE, or DELETE had actually occurred, even if no modifications take place as the result of the trigger operation. If a statement that includes an OUTPUT clause is used inside the body of a trigger, table aliases must be used to reference the trigger inserted and deleted tables to avoid duplicating column references with the INSERTED and DELETED tables associated with OUTPUT.

Define the width as 960px, or whatever you prefer, and you're good to go!

#main {
 margin: 0 auto !important;
 float: none !important;
 text-align: center;
 width: 960px;
}

(I couldn't figure this out until I fixed the width, nothing else worked.)

textcolor function is no longer supported in the latest compilers.

This the simplest way to change text color in Code Blocks. You can use system function.

To change Text Color :

#include<stdio.h> 
#include<stdlib.h> //as system function is in the standard library

int main()        
        {
          system("color 1"); //here 1 represents the text color
          printf("This is dummy program for text color");
          return 0;
        }

If you want to change both the text color & console color you just need to add another color code in system function

To change Text Color & Console Color :

system("color 41"); //here 4 represents the console color and 1 represents the text color

N.B: Don't use spaces between color code like these

system("color 4 1");

Though if you do it Code Block will show all the color codes. You can use this tricks to know all supported color codes.

You can call a reset function before appending. Something like this:

    function resetNewReviewBoardForm() {
    $("#Description").val('');
    $("#PersonName").text('');
    $("#members").empty(); //this one what worked in my case
    $("#EmailNotification").val('False');
}

Your Code is Fine just you need to place it inside the ready function.

$(document).ready( function() {
  $("#cpa-form").submit(function(e){
     e.preventDefault();
  });
}

Real shows total turn-around time for a process; while User shows the execution time for user-defined instructions and Sys is for time for executing system calls!

Real time includes the waiting time also (the waiting time for I/O etc.)

I had the same issue with Python3. My code was writing into io.BytesIO().

Replacing with io.StringIO() solved.

Do you mean append?

>>> x = [1,2,3]
>>> y = [4,5,6]
>>> x.append(y)
>>> x
[1, 2, 3, [4, 5, 6]]

Or merge?

>>> x = [1,2,3]
>>> y = [4,5,6]
>>> x + y
[1, 2, 3, 4, 5, 6]
>>> x.extend(y)
>>> x
[1, 2, 3, 4, 5, 6] 

You can now use Yeoman - Modern Web App Scaffolding Tool on node terminal using 3 easy steps.

First, you'll need to install yo and other required tools:

$ npm install -g yo bower grunt-cli gulp

To scaffold a web application, install the generator-webapp generator:

$ npm install -g generator-webapp  // create scaffolding 

Run yo and... you are all done:

$ yo webapp  // create scaffolding 

Yeoman can write boilerplate code for your entire web application or Controllers and Models. It can fire up a live-preview web server for edits and compile; not just that you can also run your unit tests, minimize and concatenate your code, optimize images, and more...

Yeoman (yo) - scaffolding tool that offers an ecosystem of framework-specific scaffolds, called generators, that can be used to perform some of the tedious tasks mentioned earlier.

Grunt / gulp - used to build, preview, and test your project.

Bower - is used for dependency management, so that you no longer have to manually download your front-end libraries.

To my knowledge, only ENV allows that, as mentioned in "Environment replacement"

Environment variables (declared with the ENV statement) can also be used in certain instructions as variables to be interpreted by the Dockerfile.

They have to be environment variables in order to be redeclared in each new containers created for each line of the Dockerfile by docker build.

In other words, those variables aren't interpreted directly in a Dockerfile, but in a container created for a Dockerfile line, hence the use of environment variable.

This day, I use both ARG (docker 1.10+, and docker build --build-arg var=value) and ENV.
Using ARG alone means your variable is visible at build time, not at runtime.

My Dockerfile usually has:

ARG var
ENV var=${var}

In your case, ARG is enough: I use it typically for setting http_proxy variable, that docker build needs for accessing internet at build time.

I was using mlab.com as the MongoDB database. I separated the connection string to a different folder named config and inside file keys.js I kept the connection string which was:

module.exports = {_x000D_
  mongoURI: "mongodb://username:[email protected]:47267/projectname"_x000D_
};

And the server code was

const express = require("express");_x000D_
const mongoose = require("mongoose");_x000D_
const app = express();_x000D_
_x000D_
// Database configuration_x000D_
const db = require("./config/keys").mongoURI;_x000D_
_x000D_
// Connect to MongoDB_x000D_
_x000D_
mongoose_x000D_
  .connect(_x000D_
    db,_x000D_
    { useNewUrlParser: true } // Need this for API support_x000D_
  )_x000D_
  .then(() => console.log("MongoDB connected"))_x000D_
  .catch(err => console.log(err));_x000D_
_x000D_
app.get("/", (req, res) => res.send("hello!!"));_x000D_
_x000D_
const port = process.env.PORT || 5000;_x000D_
_x000D_
app.listen(port, () => console.log(`Server running on port ${port}`)); // Tilde, not inverted comma

You need to write { useNewUrlParser: true } after the connection string as I did above.

Simply put, you need to do:

mongoose.connect(connectionString,{ useNewUrlParser: true } _x000D_
// Or_x000D_
MongoClient.connect(connectionString,{ useNewUrlParser: true } _x000D_
    

Here is my approach to handle some edge cases like having whitespaces and other primitive types as values

const str = " c:234 , d:sdfg ,e: true, f:null, g: undefined, h:name "; 

const strToObj = str
  .trim()
  .split(",")
  .reduce((acc, item) => {
    const [key, val = ""] = item.trim().split(":");
    let newVal = val.trim();

    if (newVal == "null") {
      newVal = null;
    } else if (newVal == "undefined") {
      newVal = void 0;
    } else if (!Number.isNaN(Number(newVal))) {
      newVal = Number(newVal);
    }else if (newVal == "true" || newVal == "false") {
      newVal = Boolean(newVal);
    }
    return { ...acc, [key.trim()]: newVal };
  }, {});

If you have a for loop like this:

for(j = 0; j<=90; j++){}

In this loop you are using shorthand provided by java language which means a postfix operator(use-then-change) which is equivalent to j=j+1 , so the changed value is initialized and used for next operation.

for(j = 0; j<=90; j+3){}

In this loop you are just increment your value by 3 but not initializing it back to j variable, so the value of j remains changed.

Either I don't understand your question, or Enumerable#find is the thing you were looking for.

This function return a sub and sorted array based in second parameter $keys

function array_sub_sort(array $values, array $keys){
    $keys = array_flip($keys);
    return array_merge(array_intersect_key($keys, $values), array_intersect_key($values, $keys));
}

Example:

$array_complete = [
    'a' => 1,
    'c' => 3,
    'd' => 4,
    'e' => 5,
    'b' => 2
];

$array_sub_sorted = array_sub_sort($array_complete, ['a', 'b', 'c']);//return ['a' => 1, 'b' => 2, 'c' => 3];

I resolved a similar problem by border-color: inherit

, see:

<li style="border-color: <?php echo $hex ?>;">...</li>

li {
    border-width: 0;
}

li:before {
    content: '';
    display: inline-block;
    float: none;
    margin-right: 10px;
    border-width: 4px;
    border-style: solid;
    border-color: inherit;
}

I prefer an id descendant selector of your #form2, like this:

$("#form2 #name").val("Hello World!");

http://api.jquery.com/descendant-selector/

If you're fetching JSON, use $.getJSON() so it automatically converts the JSON to a JS Object.

Just use mysql's DATE function:

mysql> select DATE(mytimestamp) from foo;

Another implementation:

const arr = ["H", "o", "w", " ", "t", "o", " ", "s", "p", "l", "i", "t", " ", "a", " ", "l", "o", "n", "g", " ", "a", "r", "r", "a", "y", " ", "i", "n", "t", "o", " ", "s", "m", "a", "l", "l", "e", "r", " ", "a", "r", "r", "a", "y", "s", ",", " ", "w", "i", "t", "h", " ", "J", "a", "v", "a", "S", "c", "r", "i", "p", "t"];

const size = 3; 
const res = arr.reduce((acc, curr, i) => {
  if ( !(i % size)  ) {    // if index is 0 or can be divided by the `size`...
    acc.push(arr.slice(i, i + size));   // ..push a chunk of the original array to the accumulator
  }
  return acc;
}, []);

// => [["H", "o", "w"], [" ", "t", "o"], [" ", "s", "p"], ["l", "i", "t"], [" ", "a", " "], ["l", "o", "n"], ["g", " ", "a"], ["r", "r", "a"], ["y", " ", "i"], ["n", "t", "o"], [" ", "s", "m"], ["a", "l", "l"], ["e", "r", " "], ["a", "r", "r"], ["a", "y", "s"], [",", " ", "w"], ["i", "t", "h"], [" ", "J", "a"], ["v", "a", "S"], ["c", "r", "i"], ["p", "t"]]

NB - This does not modify the original array.

Or, if you prefer a functional, 100% immutable (although there's really nothing bad in mutating in place like done above) and self-contained method:

function splitBy(size, list) {
  return list.reduce((acc, curr, i, self) => {
    if ( !(i % size)  ) {  
      return [
          ...acc,
          self.slice(i, i + size),
        ];
    }
    return acc;
  }, []);
}

[[NSDate date] timeIntervalSince1970];

It returns the number of seconds since epoch as a double. I'm almost sure you can access the milliseconds from the fractional part.

function msort(arr){
    for(var i =0;i<arr.length;i++){
        for(var j= i+1;j<arr.length;j++){
            if(arr[i]>arr[j]){
                var swap = arr[i];
                arr[i] = arr[j];
                arr[j] = swap;
            }
        }
    }
return arr;
}

Lets say that "==" operator returns true if both both operands belong to same object but when it will return true as we can't assign a single object multiple values

public static void main(String [] args){
    String s1 = "Hello";
    String s1 = "Hello";  // This is not possible to assign multiple values to single object
    if(s1 == s1){
      // Now this retruns true
   }
}

Now when this happens practically speaking, If its not happen then why this is == compares functionality....

There are two ways for case insensitive comparison:

1. Convert strings to upper case and then compare them using the strict operator (===). How strict operator treats operands read stuff at: http://www.thesstech.com/javascript/relational-logical-operators

2. Pattern matching using string methods:

   Use the "search" string method for case insensitive search. Read about search and other string methods at: http://www.thesstech.com/pattern-matching-using-string-methods

Node.prototype.insertAfter = Node.prototype.insertAfter || function (newNode, referenceNode) {
  function isNode(node) {
    return node instanceof Node;
  }

  if(arguments.length < 2){
    throw(new TypeError("Failed to execute 'insertAfter' on 'Node': 2 arguments required, but only "+ arguments.length +" present."));
  }

  if(isNode(newNode)){
    if(referenceNode === null || referenceNode === undefined){
      return this.insertBefore(newNode, referenceNode);
    }

    if(isNode(referenceNode)){
      return this.insertBefore(newNode, referenceNode.nextSibling);
    }

    throw(new TypeError("Failed to execute 'insertAfter' on 'Node': parameter 2 is not of type 'Node'."));
  }

  throw(new TypeError("Failed to execute 'insertAfter' on 'Node': parameter 1 is not of type 'Node'."));
};

You would write a comparator class, for example:

struct CompareAge {
    bool operator()(Person const & p1, Person const & p2) {
        // return "true" if "p1" is ordered before "p2", for example:
        return p1.age < p2.age;
    }
};

and use that as the comparator argument:

priority_queue<Person, vector<Person>, CompareAge>

Using greater gives the opposite ordering to the default less, meaning that the queue will give you the lowest value rather than the highest.

Do I need to double the size of the .box div to 400px by 400px to match the new high res background image

No, but you do need to set the background-size property to match the original dimensions:

@media (-webkit-min-device-pixel-ratio: 2), 
(min-resolution: 192dpi) { 

    .box{
        background:url('images/[email protected]') no-repeat top left;
        background-size: 200px 200px;
    }
}

EDIT

To add a little more to this answer, here is the retina detection query I tend to use:

@media
only screen and (-webkit-min-device-pixel-ratio: 2),
only screen and (   min--moz-device-pixel-ratio: 2),
only screen and (     -o-min-device-pixel-ratio: 2/1),
only screen and (        min-device-pixel-ratio: 2),
only screen and (                min-resolution: 192dpi),
only screen and (                min-resolution: 2dppx) { 

}

- Source

NB. This min--moz-device-pixel-ratio: is not a typo. It is a well documented bug in certain versions of Firefox and should be written like this in order to support older versions (prior to Firefox 16). - Source

As @LiamNewmarch mentioned in the comments below, you can include the background-size in your shorthand background declaration like so:

.box{
    background:url('images/[email protected]') no-repeat top left / 200px 200px;
}

However, I personally would not advise using the shorthand form as it is not supported in iOS <= 6 or Android making it unreliable in most situations.

To see which files are changed and view the actual code changes compared to the master branch you could use:

git diff --stat --patch origin master

^{NOTE: If you happen to use any of the Intellij IDEs then you can right-click your top-level project, select Git > Compare with branch > and pick the origin you want e.g. origin/master. In the file tree that will appear you can double-click the files to see a visual diff. Unlike the command-line option above you can edit your local versions from the diff window.}

First of all, set more safe initial data:

getInitialState : function() {
    return {data: {comments:[]}};
},

And ensure your ajax data.

It should work if you follow above two instructions like Demo.

Updated: you can just wrap the .map block with conditional statement.

if (this.props.data) {
  var commentNodes = this.props.data.map(function (comment){
      return (
        <div>
          <h1>{comment.author}</h1>
        </div>
      );
  });
}

If you are using Apache on Windows:

1. Check the name of the Apache service with Win+R+services.msc+Enter (if it's not ApacheX.Y, it should have the name of the software you are using with apache, e.g.: "wampapache64");
2. Start a command prompt as Administrator (using Win+R+cmd+Enter is not enough);
3. Change to Apache's directory, e.g.: cd c:\wamp\bin\apache\apache2.4.9\bin;
4. Check if the config file is OK with: httpd.exe -n "YourServiceName" -t (replace the service name by the one you found on step 1);
5. Make sure that the service is stopped: httpd.exe -k stop -n "YourServiceName"
6. Start it with: httpd.exe -k start -n "YourServiceName"

7. If it starts alright, the problem is no longer there, but if you get:

   AH00072: make_sock: could not bind to address IP:PORT_NUMBER

   AH00451: no listening sockets available, shutting down

   If the port number is not the one you wanted to use, then open the Apache config file (e.g. C:\wamp\bin\apache\apache2.4.9\conf\httpd.conf open with a code editor or wordpad, but not notepad - it does not read new lines properly) and replace the number on the line that starts with Listen with the number of the port you want, save it and repeat step 6. If it is the one you wanted to use, then continue:

8. Check the PID of the process that is using that port with Win+R+resmon+Enter, click on Network tab and then on Ports subtab;
9. Kill it with: taskkill /pid NUMBER /f (/f forces it);
10. Recheck resmon to confirm that the port is free now and repeat step 6.

This ensures that Apache's service was started properly, the configuration on virtual hosts config file as sarul mentioned (e.g.: C:\wamp\bin\apache\apache2.4.9\conf\extra\httpd-vhosts.conf) is necessary if you are setting your files path in there and changing the port as well. If you change it again, remember to restart the service: httpd.exe -k restart -n "YourServiceName".

During the download of wamp server from wampserver website you get a warning..

WARNING : Vous devez avoir installé Visual Studio 2012 : VC 11 vcredist_x64/86.exe Visual Studio 2012 VC 11 vcredist_x64/86.exe : http://www.microsoft.com/en-us/download/details.aspx?id=30679

So if you install the vcredist_xxx.exe it will be ok

In my case, I wanted to check out a new branch that has cut recently but it's it big in size and I want to save time and internet bandwidth, as I'm in a slow metered network

so I copped the previous branch that I already checked in

I went to the working directory, and from svn info, I can see it's on the previous branch I did the following command (you can find this command from svn switch --help)

svn switch ^/branches/newBranchName

go check svn info again you can see it is becoming the newBranchName go ahead and svn up

and this how I got the new branch easily, quickly with minimum data transmitting over the internet

hope sharing my case helps and speeds up your work

Get all the subviews from your root controller and send each a removeFromSuperview:

NSArray *viewsToRemove = [self.view subviews];
for (UIView *v in viewsToRemove) {
    [v removeFromSuperview];
}

The delegation concept

If there are many elements inside one parent, and you want to handle events on them of them - don’t bind handlers to each element. Instead, bind the single handler to their parent, and get the child from event.target. This site provides useful info about how to implement event delegation. http://javascript.info/tutorial/event-delegation

To change your application to a different built-in theme, just add this line under application tag in your app's manifest.xml file.

Example:

<application 
    android:theme="@android:style/Theme.Holo"/>

<application 
    android:theme="@android:style/Theme.Holo.Light"/>

<application 
    android:theme="@android:style/Theme.Black"/>

<application 
    android:theme="@android:style/Theme.DeviceDefault"/>

If you set style to DeviceDefault it will require min SDK version 14, but if you won't add a style, it will set to the device default anyway.

<uses-sdk
    android:minSdkVersion="14"/>

bobince's solution has the downside of creating a button which can be Tab-d over, but otherwise unusable. This can create confusion for keyboard users.

A different solution is to use the little-known form attribute:

<form>
    <input name="data" value="Form data here">
    <input type="submit" name="do-secondary-action" form="form2" value="Do secondary action">
    <input type="submit" name="submit" value="Submit">
</form>

<form id="form2"></form>

This is standard HTML, however unfortunately not supported in Internet Explorer.

jquery function is most important

<script>
$(function(){
    var stickyHeaderTop = $('#stickytypeheader').offset().top;

    $(window).scroll(function(){
            if( $(window).scrollTop() > stickyHeaderTop ) {
                    $('#stickytypeheader').css({position: 'fixed', top: '0px'});
                    $('#sticky').css('display', 'block');
            } else {
                    $('#stickytypeheader').css({position: 'static', top: '0px'});
                    $('#sticky').css('display', 'none');
            }
    });
});
</script>

Then use JQuery Lib...

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>

Now use HTML

<div id="header">
    <p>This text is non sticky</p>
    <p>This text is non sticky</p>
    <p>This text is non sticky</p>
    <p>This text is non sticky</p>
 </div>

<div id="stickytypeheader">
 <table width="100%">
  <tr>
    <td><a href="http://growthpages.com/">Growth pages</a></td>

    <td><a href="http://google.com/">Google</a></td>

    <td><a href="http://yahoo.com/">Yahoo</a></td>

    <td><a href="http://www.bing.com/">Bing</a></td>

    <td><a href="#">Visitor</a></td>
  </tr>
 </table>
</div>

<div id="content">

The syntax is

data.put("John","Taxi driver");

Here is a reliable solution that works with 32bit and 64bit applications.

Add these references:

using System.Diagnostics;

using System.Management;

Add this method to your project:

public static string GetProcessPath(int processId)
{
    string MethodResult = "";
    try
    {
        string Query = "SELECT ExecutablePath FROM Win32_Process WHERE ProcessId = " + processId;

        using (ManagementObjectSearcher mos = new ManagementObjectSearcher(Query))
        {
            using (ManagementObjectCollection moc = mos.Get())
            {
                string ExecutablePath = (from mo in moc.Cast<ManagementObject>() select mo["ExecutablePath"]).First().ToString();

                MethodResult = ExecutablePath;

            }

        }

    }
    catch //(Exception ex)
    {
        //ex.HandleException();
    }
    return MethodResult;
}

Now use it like so:

int RootProcessId = Process.GetCurrentProcess().Id;

GetProcessPath(RootProcessId);

Notice that if you know the id of the process, then this method will return the corresponding ExecutePath.

Extra, for those interested:

Process.GetProcesses() 

...will give you an array of all the currently running processes, and...

Process.GetCurrentProcess()

...will give you the current process, along with their information e.g. Id, etc. and also limited control e.g. Kill, etc.*

I am not too sure I would go and use an enum as a full fledged class - this is an object oriented language, and one of the most basic tenets of object orientation is that a class should do one thing and do it well.

An enum is doing a pretty good job at being an enum, and a class is doing a good job as a class. Mixing the two I have a feeling will get you into trouble - for example, you can't pass an instance of an enum as a parameter to a method, primarily because you can't create an instance of an enum.

So, even though you might be able to enum.process() does not mean that you should.

If you want to delete one item

wishlist = Wishlist.objects.get(id = 20)
wishlist.delete()

If you want to delete all items in Wishlist for example

Wishlist.objects.all().delete()

So you can use one stack to do a post order traversal.

private void PostOrderTraversal(Node pos) {
    Stack<Node> stack = new Stack<Node>();
    do {
        if (pos==null && (pos=stack.peek().right)==null) {
            for (visit(stack.peek()); stack.pop()==(stack.isEmpty()?null:stack.peek().right); visit(stack.peek())) {}
        } else if(pos!=null) {
            stack.push(pos);
            pos=pos.left;
        }
    } while (!stack.isEmpty());
}

You can also use .filter()

$('.slide-link').filter('[data-slide="0"]').addClass('active');

var wrapper = $(document.body);

strings = [
    "19 51 2.108997",
    "20 47 2.1089"
];

$.each(strings, function(key, value) {
    var tmp = value.split(" ");
    $.each([
        tmp[0] + " " + tmp[1],
        tmp[2]
    ], function(key, value) {
        $("<span>" + value + "</span>").appendTo(wrapper);
    }); 
});

System.setProperty("javax.net.ssl.trustStore", path_to_your_jks_file);

As Wingman said, Google App Engine is a great solution for your scenario.

You can get some information about GAE+Android here: https://developers.google.com/eclipse/docs/appengine_connected_android

And from this Google IO 2012 session: http://www.youtube.com/watch?v=NU_wNR_UUn4

I get this error message and it mentions options.body

I had this originally

request.post({
    url: apiServerBaseUrl + '/v1/verify',
    body: {
        email: req.user.email
    }
});

I changed it to this:

request.post({
    url: apiServerBaseUrl + '/v1/verify',
    body: JSON.stringify({
        email: req.user.email
    })
});

and it seems to work now without the error message...seems like bug though.

I think this is the more official way to do it:

 request.post({
        url: apiServerBaseUrl + '/v1/verify',
        json: true,
        body: {
            email: req.user.email
        }
    });

use following command from mongo shell to drop db

use ; db.dropDatabase();

Use the File.WriteAllText method. It creates the file if it doesn't exist and overwrites it if it exists.

You'll need a to create an "app" on Twitter (and you need a Twitter account to do this).

Then, you need to use OAuth to make an authorized request to Twitter.

You can use the GET statuses/user_timeline resource to get a list of recent tweets.

None of these answers were working for me. A couple of them would indeed print all the columns, but it would look sloppy. As in all the information was there, but it wasn't formatted correctly. I'm using a terminal inside of Neovim so I suspect that to be the reason.

This mini function does exactly what I need, just change df_data in the two places it is for your dataframe name (col_range is set to what pandas naturally shows, for me it is 5 but it could be bigger or smaller for you).

import math
col_range = 5
for _ in range(int(math.ceil(len(df_data.columns)/col_range))):
    idx1 = _*col_range
    idx2 = idx1+col_range
    print(df_data.iloc[:, idx1:idx2].describe())

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS

// Example using HTTP POST operation

var page = require('webpage').create(),
    server = 'http://posttestserver.com/post.php?dump',
    data = 'universe=expanding&answer=42';

page.open(server, 'post', data, function (status) {
    if (status !== 'success') {
        console.log('Unable to post!');
    } else {
        console.log(page.content);
    }
    phantom.exit();
});

Assuming AdvancedFormat is a bool, you need to declare and use a BooleanToVisibilityConverter:

<!-- In your resources section of the XAML -->
<BooleanToVisibilityConverter x:Key="BoolToVis" />

<!-- In your Button declaration -->
<Button
 Height="50" Width="50"
 Style="{StaticResource MyButtonStyle}"
 Command="{Binding SmallDisp}" CommandParameter="{Binding}" 
Cursor="Hand" Visibility="{Binding Path=AdvancedFormat, Converter={StaticResource BoolToVis}}"/>

Note the added Converter={StaticResource BoolToVis}.

This is a very common pattern when working with MVVM. In theory you could do the conversion yourself on the ViewModel property (i.e. just make the property itself of type Visibility) though I would prefer not to do that, since now you are messing with the separation of concerns. An item's visbility should really be up to the View.

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

You can simplify it to

if ($user_sam -and $user_case) {
  ...
}

because empty strings coerce to $false (and so does $null, for that matter).

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

To add to this you can also use inline if condition with && and || operators. Like this

var a = 2;
var b = 0;

var c = (a > b || b == 0)? "do something" : "do something else";

It's because savefig overrides the facecolor for the background of the figure.

(This is deliberate, actually... The assumption is that you'd probably want to control the background color of the saved figure with the facecolor kwarg to savefig. It's a confusing and inconsistent default, though!)

The easiest workaround is just to do fig.savefig('whatever.png', facecolor=fig.get_facecolor(), edgecolor='none') (I'm specifying the edgecolor here because the default edgecolor for the actual figure is white, which will give you a white border around the saved figure)

Hope that helps!

The reason it has no effect is because at the link-time the linker tries to resolve the extern definition (in your case extern int f()). It doesn't matter if it finds it in the same file or a different file, as long as it is found.

Hope this answers your question.

You can use the name property for that particular element. For example to set a border of 2px around an input element with name xyz, you can use;

$(function() {
    $("input[name = 'xyz']").css("border","2px solid red");
})

DEMO

Summarizing the most relevant comments in one answer:

• this is a known bug
• there are workarounds but you might not need them (read on)
• it happens when elements are placed directly inside the body, rather than inside a container-fluid div or another containing div. Placing them directly in the body is exactly what most people do when testing stuff locally. Once you place your code in the complete page (so within a container-fluid or another container div) you will not face this problem (no need to change anything).

Use swfobject. it replaces a div with the flash if it is installed. see: http://code.google.com/p/swfobject/

For what it's worth, when I did this I found that no folder should be include in the path in the css file. For instance if I have app/assets/images/example.png, and I put this in my css file...

div.example { background: url('example.png'); }

... then somehow it magically works. I figured this out by running the rake assets:precompile task, which just sucks everything out of all your load paths and dumps it in a junk drawer folder: public/assets. That's ironic, IMO...

In any case this means you don't need to put any folder paths, everything in your assets folders will all end up living in one huge directory. How this system resolves file name conflicts is unclear, you may need to be careful about that.

Kind of frustrating there aren't better docs out there for this big of a change.

Try This,

alter session set "_convert_set_to_join"= true;

The other alternative is to rewrite the SQL query manually [replacing the minus operator with a NOT IN subquery] evidences about 30% improvement in execution time .

 select * 
   from A 
    where (col1,col2,?) not in 
   (select col1,col2,? from B) 
   union all 
   select * from B 
  where (col1,col2,?) not in 
  (select col1,col2,? from A); 

I have referred from this post click here

'\u0000' stands for null . So if you print an uninitialized char variable , you'll get nothing.

Basic docker-compose.yml with extra hosts:

version: '3'
services:
api:
    build: .
    ports:
        - "5003:5003"
    extra_hosts:
        - "your-host.name.com:162.242.195.82" #host and ip
        - "your-host--1.name.com your-host--2.name.com:50.31.209.229" #multiple hostnames with same ip
        

The content in the /etc/hosts file in the created container:

162.242.195.82  your-host.name.com
50.31.209.229   your-host--1.name.com your-host--2.name.com

You can check the /etc/hosts file with the following commands:

$ docker-compose -f path/to/file/docker-compose.yml run api bash  # 'api' is service name
#then inside container bash
root@f7c436910676:/app# cat /etc/hosts

The big point, and the elephant in the room and all that, is that if your application can get hold of the password, then a hacker with access to the box can get hold of it too!

The only way somewhat around this, is that the application asks for the "master password" on the console using Standard Input, and then uses this to decrypt the passwords stored on file. Of course, this completely makes is impossible to have the application start up unattended along with the OS when it boots.

However, even with this level of annoyance, if a hacker manages to get root access (or even just access as the user running your application), he could dump the memory and find the password there.

The thing to ensure, is to not let the entire company have access to the production server (and thereby to the passwords), and make sure that it is impossible to crack this box!

'So from this discussion i am thinking this should be the code then.

With nginx you can send both tokens like this (even though it's against the standard):

Authorization: Basic basic-token,Bearer bearer-token

This works as long as the basic token is first - nginx successfully forwards it to the application server.

And then you need to make sure your application can properly extract the Bearer from the above string.

Actually, I needed the following...get rid of the decimals without rounding so "12.23" needs to show as "12". In SSRS, do not format the number as a percent. Leave the formatting as default (no formatting applied) then in the expression do the following: =Fix(Fields!PctAmt.Value*100))

Multiply the number by 100 then apply the FIX function in SSRS which returns only the integer portion of a number.

try this:

select salesid,count (salesid) from AXDelNotesNoTracking group by salesid having count (salesid) >1

Have you tried git push? gitref.org has a nice section dealing with remote repositories.

You can also get help from the command line using the --help option. For example:

% git push --help
GIT-PUSH(1)                             Git Manual                             GIT-PUSH(1)



NAME
       git-push - Update remote refs along with associated objects

SYNOPSIS
       git push [--all | --mirror | --tags] [-n | --dry-run] [--receive-pack=<git-receive-pack>]
                  [--repo=<repository>] [-f | --force] [-v | --verbose] [-u | --set-upstream]
                  [<repository> [<refspec>...]]
...

use this syntax: alter table table_name modify column col_name varchar (10000);

Starting with Spring 4.1, We can directly set the property in application.yml using the @TestPropertySource annotation.

@RunWith(SpringRunner.class)
@SpringBootTest
@TestPropertySource(properties = {"yoursection.yourparameter=your_value"})
public MyIntTest
{
 //your test methods
}

Just convert your yaml parameters into complete property structure. For example: If content of application.yml is like below

yoursection:
  yourparameter:your_value

Then value to go inside the @TestPropertySource will be,

yoursection.yourparameter=your_value

You can try that command

git clean -df

Each row in /proc/$PID/maps describes a region of contiguous virtual memory in a process or thread. Each row has the following fields:

address           perms offset  dev   inode   pathname
08048000-08056000 r-xp 00000000 03:0c 64593   /usr/sbin/gpm

• address - This is the starting and ending address of the region in the process's address space
• permissions - This describes how pages in the region can be accessed. There are four different permissions: read, write, execute, and shared. If read/write/execute are disabled, a - will appear instead of the r/w/x. If a region is not shared, it is private, so a p will appear instead of an s. If the process attempts to access memory in a way that is not permitted, a segmentation fault is generated. Permissions can be changed using the mprotect system call.
• offset - If the region was mapped from a file (using mmap), this is the offset in the file where the mapping begins. If the memory was not mapped from a file, it's just 0.
• device - If the region was mapped from a file, this is the major and minor device number (in hex) where the file lives.
• inode - If the region was mapped from a file, this is the file number.
• pathname - If the region was mapped from a file, this is the name of the file. This field is blank for anonymous mapped regions. There are also special regions with names like [heap], [stack], or [vdso]. [vdso] stands for virtual dynamic shared object. It's used by system calls to switch to kernel mode. Here's a good article about it: "What is linux-gate.so.1?"

You might notice a lot of anonymous regions. These are usually created by mmap but are not attached to any file. They are used for a lot of miscellaneous things like shared memory or buffers not allocated on the heap. For instance, I think the pthread library uses anonymous mapped regions as stacks for new threads.

When I work with UIStackView animation, besides removeAllAnimations() I need to set some values to initial one because removeAllAnimations() can set them to unpredictable state. I have stackView with view1 and view2 inside, and one view should be visible and one hidden:

public func configureStackView(hideView1: Bool, hideView2: Bool) {
    let oldHideView1 = view1.isHidden
    let oldHideView2 = view2.isHidden
    view1.layer.removeAllAnimations()
    view2.layer.removeAllAnimations()
    view.layer.removeAllAnimations()
    stackView.layer.removeAllAnimations()
    // after stopping animation the values are unpredictable, so set values to old
    view1.isHidden = oldHideView1 //    <- Solution is here
    view2.isHidden = oldHideView2 //    <- Solution is here

    UIView.animate(withDuration: 0.3,
                   delay: 0.0,
                   usingSpringWithDamping: 0.9,
                   initialSpringVelocity: 1,
                   options: [],
                   animations: {
                    view1.isHidden = hideView1
                    view2.isHidden = hideView2
                    stackView.layoutIfNeeded()
    },
                   completion: nil)
}

You might forgetting to include.. StartUp.cs/Configure()

app.UseSwagger();

Check if you forgot to include, you error must be remove.

final ByteBuffer buffer;
if (buffer.hasArray()) {
    final byte[] array = buffer.array();
    final int arrayOffset = buffer.arrayOffset();
    return Arrays.copyOfRange(array, arrayOffset + buffer.position(),
                              arrayOffset + buffer.limit());
}
// do something else

You can paste it like this:

= "2010-12-20" - 180

And don't forget to format the cell as a Date [CTRL]+[F1] / Number Tab

I would consider using the attr_defaults found here. Your wildest dreams will come true.

This is the perfect and most easiest solution.I always use this in my app.

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

I think you can use asset('/')

This should solve your problem, you should try to run the following below:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser 

I believe the following work in version 0.11 and above. To check the version:

$ ipython --version

It may be worth adding this information to your question.

Solution:

You need to find the file ipython_notebook_config.py. Depending on your installation process this should be in somewhere like

.config/ipython/profile_default/ipython_notebook_config.py

where .config is in your home directory.

Once you have located this file find the following lines

# Subset of matplotlib rcParams that should be different for the inline backend.
# c.InlineBackend.rc = {'font.size': 10, 'figure.figsize': (6.0, 4.0), 'figure.facecolor': 'white', 'savefig.dpi': 72, 'figure.subplot.bottom': 0.125, 'figure.edgecolor': 'white'}

Uncomment this line c.InlineBack... and define your default figsize in the second dictionary entry.

Note that this could be done in a python script (and hence interactively in IPython) using

pylab.rcParams['figure.figsize'] = (10.0, 8.0)

Use Lambda to find the index in the List and use this index to replace the list item.

List<string> listOfStrings = new List<string> {"abc", "123", "ghi"};
listOfStrings[listOfStrings.FindIndex(ind=>ind.Equals("123"))] =  "def";

I also had same problem. I got error messages that related to cannot copy since access to path denied. In my case all my dll's and xml files and so on are place at D:\TFS\Example\Bin\Debug folder.

I right clicked on Bin folder and clicked Properties and saw that Read-only check box is checked under Attributes.

I un-checked Read only check box and cliked Apply and clicked OK on the new popup that is shown.

I went back to Visual Studio and build my solution which was giving me error messages.

Voilaa.. This time it build successfully without errors.

I donot know whether this is perfect but I did this to solve my issue.

Is this any help?

#include <stdio.h>

#define MAX 10

int main()
{
    char grid[MAX][MAX];
    int i,j,row,col;

    printf("Please enter your grid size: ");
    scanf("%d %d", &row, &col);


    for (i = 0; i < row; i++) {
        for (j = 0; j < col; j++) {
            grid[i][j] = '.';
            printf("%c ", grid[i][j]);
        }
        printf("\n");
    }

    return 0;
}

See official API documentation https://api.jquery.com/selected-selector/

This good works:

$( "select" ).on('change',function() {
  var str = "";
  // For multiple choice
  $( "select option:selected" ).each(function() {
    str += $( this ).val() + " "; 
  });
});

and

$( "select" ).on('change',function() {
  // For unique choice
  var selVal = $( "select option:selected" ).val(); 
});

and be easy for unique choice

var SelVal = $( "#idSelect option:selected" ).val();

Just wanted to make a time comparison for both solutions (for 30K rows DF):

In [1]: df = DataFrame({'foo':['a','b','c'], 'bar':[1, 2, 3], 'new':['apple', 'banana', 'pear']})

In [2]: big = pd.concat([df] * 10**4, ignore_index=True)

In [3]: big.shape
Out[3]: (30000, 3)

In [4]: %timeit big.apply(lambda x:'%s_%s_%s' % (x['bar'],x['foo'],x['new']),axis=1)
1 loop, best of 3: 881 ms per loop

In [5]: %timeit big['bar'].astype(str)+'_'+big['foo']+'_'+big['new']
10 loops, best of 3: 44.2 ms per loop

a few more options:

In [6]: %timeit big.ix[:, :-1].astype(str).add('_').sum(axis=1).str.cat(big.new)
10 loops, best of 3: 72.2 ms per loop

In [11]: %timeit big.astype(str).add('_').sum(axis=1).str[:-1]
10 loops, best of 3: 82.3 ms per loop

Use stopPropagation method, see an example:

$("#clickable a").click(function(e) {
   e.stopPropagation();
});

As said by jQuery Docs:

stopPropagation method prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.

Keep in mind that it does not prevent others listeners to handle this event(ex. more than one click handler for a button), if it is not the desired effect, you must use stopImmediatePropagation instead.

Next row

SELECT * FROM `foo` LIMIT number++ , 1

Previous row

SELECT * FROM `foo` LIMIT number-- , 1

sample next row

SELECT * FROM `foo` LIMIT 1 , 1
SELECT * FROM `foo` LIMIT 2 , 1
SELECT * FROM `foo` LIMIT 3 , 1

sample previous row

SELECT * FROM `foo` LIMIT -1 , 1
SELECT * FROM `foo` LIMIT -2 , 1
SELECT * FROM `foo` LIMIT -3 , 1

SELECT * FROM `foo` LIMIT 3 , 1
SELECT * FROM `foo` LIMIT 2 , 1
SELECT * FROM `foo` LIMIT 1 , 1

This should work:

date +%s

A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer's processor uses

I found it easiest to just read the entire line into one column then parse out the data using XML.

IF (OBJECT_ID('tempdb..#data') IS NOT NULL) DROP TABLE #data
CREATE TABLE #data (data VARCHAR(MAX))

BULK INSERT #data FROM 'E:\filefromabove.txt' WITH (FIRSTROW = 2, ROWTERMINATOR = '\n')

IF (OBJECT_ID('tempdb..#dataXml') IS NOT NULL) DROP TABLE #dataXml
CREATE TABLE #dataXml (ID INT NOT NULL IDENTITY(1,1) PRIMARY KEY CLUSTERED, data XML)

INSERT #dataXml (data)
SELECT CAST('<r><d>' + REPLACE(data, '|', '</d><d>') + '</d></r>' AS XML)
FROM #data

SELECT  d.data.value('(/r//d)[1]', 'varchar(max)') AS col1,
        d.data.value('(/r//d)[2]', 'varchar(max)') AS col2,
        d.data.value('(/r//d)[3]', 'varchar(max)') AS col3
FROM #dataXml d

• Hit F12 to open Dev Tools
• Click the Sources tab
• On right-hand side, scroll down to "Event Listener Breakpoints", and expand tree
• Click on the events you want to listen for.
• Interact with the target element, if they fire you will get a break point in the debugger

Similarly, you can right click on the target element -> select "inspect element" Scroll down on the right side of the dev frame, at the bottom is 'event listeners'. Expand the tree to see what events are attached to the element. Not sure if this works for events that are handled through bubbling (I'm guessing not)
