The time.Parse function does not do Unix timestamps. Instead you can use strconv.ParseInt to parse the string to int64 and create the timestamp with time.Unix:

package main

import (
    "fmt"
    "time"
    "strconv"
)

func main() {
    i, err := strconv.ParseInt("1405544146", 10, 64)
    if err != nil {
        panic(err)
    }
    tm := time.Unix(i, 0)
    fmt.Println(tm)
}

Output:

2014-07-16 20:55:46 +0000 UTC

Playground: http://play.golang.org/p/v_j6UIro7a

Edit:

Changed from strconv.Atoi to strconv.ParseInt to avoid int overflows on 32 bit systems.

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

You can use Smartface for developing your app with javascript and deploy to stores directly without a Mac. What they say is below.

With the Cloud Build module, Smartface removes all the hassle of application deployment. You don’t need to worry about managing code signing certificates and having a Mac to sign your apps. Smartface Cloud can store all your iOS certificates and Android keystores in one place and signing and building is fully in the cloud. No matter which operating system you use, you can get store-ready (or enterprise distribution) binaries. Smartface frees you from the lock-in to Mac and allows you to use your favorite operating system for development.

This is an old question maybe even before actual Optional type was introduced but these days you can consider few things: - use method overloading - use Optional type which has advantage of avoiding passing NULLs around Optional type was introduced in Java 8 before it was usually used from third party lib such as Google's Guava. Using optional as parameters / arguments can be consider as over-usage as the main purpose was to use it as a return time.

The only way I could get this to work is to pass the JSON as a string and then deserialise it using JavaScriptSerializer.Deserialize<T>(string input), which is pretty strange if that's the default deserializer for MVC 4.

My model has nested lists of objects and the best I could get using JSON data is the uppermost list to have the correct number of items in it, but all the fields in the items were null.

This kind of thing should not be so hard.

    $.ajax({
        type: 'POST',
        url: '/Agri/Map/SaveSelfValuation',
        data: { json: JSON.stringify(model) },
        dataType: 'text',
        success: function (data) {

    [HttpPost]
    public JsonResult DoSomething(string json)
    {
        var model = new JavaScriptSerializer().Deserialize<Valuation>(json);

I have tried these methods and find that they dont work for my needs. In my case, I needed to inject json rendered server side into the main template of the page, so when it loads and angular inits, the data is already there and doesnt have to be retrieved (large dataset).

The easiest solution that I have found is to do the following:

In your angular code outside of the app, module and controller definitions add in a global javascript value - this definition MUST come before the angular stuff is defined.

Example:

'use strict';

//my data variable that I need access to.
var data = null;

angular.module('sample', [])

Then in your controller:

.controller('SampleApp', function ($scope, $location) {

$scope.availableList = [];

$scope.init = function () {
    $scope.availableList = data;
}

Finally, you have to init everything (order matters):

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
  <script src="/path/to/your/angular/js/sample.js"></script>
  <script type="text/javascript">
      data = <?= json_encode($cproducts); ?>
  </script>

Finally initialize your controller and init function.

  <div ng-app="samplerrelations" ng-controller="SamplerApp" ng-init="init();">

By doing this you will now have access to whatever data you stuffed into the global variable.

Very easy:

Here is what you want:

import os.path as path

two_up =  path.abspath(path.join(__file__ ,"../.."))

I was facing this issue due to empty space at the end of the password(spring.rabbitmq.password=rabbit ) in spring boot application.properties got resolved on removing the empty space. Hope this checklist helps some one facing this issue.

And if someone think it could help. Here is @Daniel Vérité's function, with another param that accept names of columns that can be used in search. This way it decrease the time of processing. At least in my test it reduced a lot.

CREATE OR REPLACE FUNCTION search_columns(
    needle text,
    haystack_columns name[] default '{}',
    haystack_tables name[] default '{}',
    haystack_schema name[] default '{public}'
)
RETURNS table(schemaname text, tablename text, columnname text, rowctid text)
AS $$
begin
  FOR schemaname,tablename,columnname IN
      SELECT c.table_schema,c.table_name,c.column_name
      FROM information_schema.columns c
      JOIN information_schema.tables t ON
        (t.table_name=c.table_name AND t.table_schema=c.table_schema)
      WHERE (c.table_name=ANY(haystack_tables) OR haystack_tables='{}')
        AND c.table_schema=ANY(haystack_schema)
        AND (c.column_name=ANY(haystack_columns) OR haystack_columns='{}')
        AND t.table_type='BASE TABLE'
  LOOP
    EXECUTE format('SELECT ctid FROM %I.%I WHERE cast(%I as text)=%L',
       schemaname,
       tablename,
       columnname,
       needle
    ) INTO rowctid;
    IF rowctid is not null THEN
      RETURN NEXT;
    END IF;
 END LOOP;
END;
$$ language plpgsql;

Bellow is an example of usage of the search_function created above.

SELECT * FROM search_columns('86192700'
    , array(SELECT DISTINCT a.column_name::name FROM information_schema.columns AS a
            INNER JOIN information_schema.tables as b ON (b.table_catalog = a.table_catalog AND b.table_schema = a.table_schema AND b.table_name = a.table_name)
        WHERE 
            a.column_name iLIKE '%cep%' 
            AND b.table_type = 'BASE TABLE'
            AND b.table_schema = 'public'
    )

    , array(SELECT b.table_name::name FROM information_schema.columns AS a
            INNER JOIN information_schema.tables as b ON (b.table_catalog = a.table_catalog AND b.table_schema = a.table_schema AND b.table_name = a.table_name)
        WHERE 
            a.column_name iLIKE '%cep%' 
            AND b.table_type = 'BASE TABLE'
            AND b.table_schema = 'public')
);

User this function:-

function dateRange($first, $last, $step = '+1 day', $format = 'Y-m-d' ) {
                $dates = array();
                $current = strtotime($first);
                $last = strtotime($last);

                while( $current <= $last ) {    
                    $dates[] = date($format, $current);
                    $current = strtotime($step, $current);
                }
                return $dates;
        }

Usage / function call:-

Increase by one day:-

dateRange($start, $end); //increment is set to 1 day.

Increase by Month:-

dateRange($start, $end, "+1 month");//increase by one month

use third parameter if you like to set date format:-

   dateRange($start, $end, "+1 month", "Y-m-d H:i:s");//increase by one month and format is mysql datetime

Simple answer

If you want to match single character, put it inside those brackets [ ]

Examples

• match + ...... [+] or +
• match a ...... a
• match & ...... &

...and so on. You can check your regular expresion online on this site: https://regex101.com/

Some SelectMany may not be necessary. Below 2 queries give the same result.

Customers.Where(c=>c.Name=="Tom").SelectMany(c=>c.Orders)

Orders.Where(o=>o.Customer.Name=="Tom")

For 1-to-Many relationship,

1. if Start from "1", SelectMany is needed, it flattens the many.
2. if Start from "Many", SelectMany is not needed. (still be able to filter from "1", also this is simpler than below standard join query)

from o in Orders
join c in Customers on o.CustomerID equals c.ID
where c.Name == "Tom"
select o

I think this may help you , both index and columns of the values.

value you are looking for is not duplicated:

poz=matrix[matrix==minv].dropna(axis=1,how='all').dropna(how='all')
value=poz.iloc[0,0]
index=poz.index.item()
column=poz.columns.item()

you can get its index and column

duplicated:

matrix=pd.DataFrame([[1,1],[1,np.NAN]],index=['q','g'],columns=['f','h'])
matrix
Out[83]: 
   f    h
q  1  1.0
g  1  NaN
poz=matrix[matrix==minv].dropna(axis=1,how='all').dropna(how='all')
index=poz.stack().index.tolist()
index
Out[87]: [('q', 'f'), ('q', 'h'), ('g', 'f')]

you will get a list

ionic -v

Ionic CLI update available: 5.2.4 ? 5.2.5
Run npm i -g ionic to update

It's a measureable difference.

Run the following:

Create Table #TempTester (id int, col1 varchar(20), value varchar(20))
go

INSERT INTO #TempTester (id, col1, value)
VALUES
(1, 'this is #1', 'abcdefghij')
GO

INSERT INTO #TempTester (id, col1, value)
VALUES
(2, 'this is #2', 'foob'),
(3, 'this is #3', 'abdefghic'),
(4, 'this is #4', 'other'),
(5, 'this is #5', 'zyx'),
(6, 'this is #6', 'zyx'),
(7, 'this is #7', 'zyx'),
(8, 'this is #8', 'klm'),
(9, 'this is #9', 'klm'),
(10, 'this is #10', 'zyx')
GO 10000

CREATE CLUSTERED INDEX ixId ON #TempTester(id)CREATE CLUSTERED INDEX ixId ON #TempTester(id)

CREATE NONCLUSTERED INDEX ixTesting ON #TempTester(value)

Then:

SET SHOWPLAN_XML ON

Then:

SELECT * FROM #TempTester WHERE value LIKE 'abc%'

SELECT * FROM #TempTester WHERE value = 'abcdefghij'

The resulting execution plan shows you that the cost of the first operation, the LIKE comparison, is about 10 times more expensive than the = comparison.

If you can use an = comparison, please do so.

I don't think there is a SAP parameter for that kind of result. Though the code below will deliver.

LOOP AT intTab.

  AT END OF value.

    result = sy-tabix.

    write result.  

  ENDAT.

ENDLOOP.

You can quite simply add the line:

source ~/.profile

To the bottom of your shell rc file - if you are using bash then it would be your ~/.bash_profile if you are using zsh it would be your ~/.zshrc

Then open a new Terminal window and type ports -v you should see output that looks like the following:

~ [ port -v                                                                                                              ] 12:12 pm
MacPorts 2.1.3

Hope that helps.

I am not sure if this has to be explicitly enabled anywhere..but for this to work in the first place you need to include the javadoc jar files with the related jars in your project. Then when you do a Cntrl+Space it shows autocomplete and javadocs.

It won't be possible if you like to directly download and install the app from your website. There is a different way for enterprise to deploy and install app over the air. Your URL should point to a web service that hosts a manifest plist file in predefined format required by Apple. This service should return the url of manifest file which can then be used as below:

NSString *urlString = // url string where your manifest.plist is deployed on your server.
NSURL *installationURL = [NSURL URLWithString:[NSString stringWithFormat:@"itms-services://?action=download-manifest&url=%@",[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];
[[UIApplication sharedApplication] openURL];

Hope this answers your question.

I've create a library, available on Packagist, that performs this function: https://packagist.org/packages/grasmash/yaml-expander

Example YAML file:

type: book
book:
  title: Dune
  author: Frank Herbert
  copyright: ${book.author} 1965
  protaganist: ${characters.0.name}
  media:
    - hardcover
characters:
  - name: Paul Atreides
    occupation: Kwisatz Haderach
    aliases:
      - Usul
      - Muad'Dib
      - The Preacher
  - name: Duncan Idaho
    occupation: Swordmaster
summary: ${book.title} by ${book.author}
product-name: ${${type}.title}

Example logic:

// Parse a yaml string directly, expanding internal property references.
$yaml_string = file_get_contents("dune.yml");
$expanded = \Grasmash\YamlExpander\Expander::parse($yaml_string);
print_r($expanded);

Resultant array:

array (
  'type' => 'book',
  'book' => 
  array (
    'title' => 'Dune',
    'author' => 'Frank Herbert',
    'copyright' => 'Frank Herbert 1965',
    'protaganist' => 'Paul Atreides',
    'media' => 
    array (
      0 => 'hardcover',
    ),
  ),
  'characters' => 
  array (
    0 => 
    array (
      'name' => 'Paul Atreides',
      'occupation' => 'Kwisatz Haderach',
      'aliases' => 
      array (
        0 => 'Usul',
        1 => 'Muad\'Dib',
        2 => 'The Preacher',
      ),
    ),
    1 => 
    array (
      'name' => 'Duncan Idaho',
      'occupation' => 'Swordmaster',
    ),
  ),
  'summary' => 'Dune by Frank Herbert',
);

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

Some general constructor tips:

• Try to focus all initialization in a single constructor and call it from the other constructors
  • This works well if multiple constructors exist to simulate default parameters
• Never call a non-final method from a constructor
  • Private methods are final by definition
  • Polymorphism can kill you here; you can end up calling a subclass implementation before the subclass has been initialized
  • If you need "helper" methods, be sure to make them private or final
• Be explicit in your calls to super()
  • You would be surprised at how many Java programmers don't realize that super() is called even if you don't explicitly write it (assuming you don't have a call to this(...) )

• Know the order of initialization rules for constructors. It's basically:

  1. this(...) if present (just move to another constructor)
  2. call super(...) [if not explicit, call super() implicitly]
  3. (construct superclass using these rules recursively)
  4. initialize fields via their declarations
  5. run body of current constructor
  6. return to previous constructors (if you had encountered this(...) calls)

The overall flow ends up being:

• move all the way up the superclass hierarchy to Object
• while not done
  • init fields
  • run constructor bodies
  • drop down to subclass

For a nice example of evil, try figuring out what the following will print, then run it

package com.javadude.sample;

/** THIS IS REALLY EVIL CODE! BEWARE!!! */
class A {
    private int x = 10;
    public A() {
        init();
    }
    protected void init() {
        x = 20;
    }
    public int getX() {
        return x;
    }
}

class B extends A {
    private int y = 42;
    protected void init() {
        y = getX();
    }
    public int getY() {
        return y;
    }
}

public class Test {
    public static void main(String[] args) {
        B b = new B();
        System.out.println("x=" + b.getX());
        System.out.println("y=" + b.getY());
    }
}

I'll add comments describing why the above works as it does... Some of it may be obvious; some is not...

You can use generated columns from MYSQL 5.7.

Example Usage:

ALTER TABLE tbl_test
ADD COLUMN calc_val INT 
GENERATED ALWAYS AS (((`column1` - 1) * 16) + `column2`) STORED;

VIRTUAL / STORED

• Virtual: calculated on the fly when a record is read from a table (default)
• Stored: calculated when a new record is inserted/updated within the table

I know this thread has been idle for a while, but I just wanted to add my two cents to supplement jariq's comment...

Per manual, you don't necessary want to use -password option.

Let's say mykey.key has a password and your want to protect iphone-dev.p12 with another password, this is what you'd use:

pkcs12 -export -inkey mykey.key -in developer_identity.pem -out iphone_dev.p12 -passin pass:password_for_mykey -passout pass:password_for_iphone_dev

Have fun scripting!!

Since nobody mentioned it, MATLAB also has the metaclass function, which returns an object with various bits of information about the passed-in entity. These meta.class objects can be useful for tests of inheritance (via common comparison operators).

For example:

>> metaclass(magic(1))

ans = 

  class with properties:

                     Name: 'double'
              Description: ''
      DetailedDescription: ''
                   Hidden: 0
                   Sealed: 0
                 Abstract: 0
              Enumeration: 0
          ConstructOnLoad: 0
         HandleCompatible: 0
          InferiorClasses: {0×1 cell}
        ContainingPackage: [0×0 meta.package]
     RestrictsSubclassing: 0
             PropertyList: [0×1 meta.property]
               MethodList: [272×1 meta.method]
                EventList: [0×1 meta.event]
    EnumerationMemberList: [0×1 meta.EnumeratedValue]
           SuperclassList: [0×1 meta.class]

>> ?containers.Map <= ?handle

ans =

  logical

   1

We can see that class(someObj) is equivalent to the Name field of the result of metaclass(someObj).

Also, if, like me, you add controls directly in XAML (not using the editor), you might get frustrated that it won't stretch to the available height, even after setting those two properties.

To make the TextBox stretch, set the Height="Auto".

UPDATE:

In retrospect, I think this must have been necessary thanks to a default style for TextBoxes specifying the height to some standard for the application somewhere in the App resources. It may be worthwhile checking this if this helped you.

Using CSS, of course...

label { display: block; width: 100px; }

The width attribute is deprecated, and CSS should always be used to control these kinds of presentational styles.

The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).

As RFC 5280 says:

The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.

X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.

The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".

In the context of the article you're linking to, the subject would be the user/owner of the cert.

I am working for customer that has a big project that is using Linq-to-SQL. When the project started it was the obvious choice, because Entity Framework was lacking some major features at that time and performance of Linq-to-SQL was much better.

Now EF has evolved and Linq-to-SQL is lacking async support, which is great for highly scalable services. We have 100+ requests per second sometimes and despite we have optimized our databases, most queries still take several milliseconds to complete. Because of the synchronous database calls, the thread is blocked and not available for other requests.

We are thinking to switch to Entity Framework, solely for this feature. It's a shame that Microsoft didn't implement async support into Linq-to-SQL (or open-sourced it, so the community could do it).

Addendum December 2018: Microsoft is moving towards .NET Core and Linq-2-SQL isn't support on .NET Core, so you need to move to EF to make sure you can migrate to EF.Core in the future.

There are also some other options to consider, such as LLBLGen. It's a mature ORM solution that exists already a long time and has been proven more future-proof then the MS data solutions (ODBC, ADO, ADO.NET, Linq-2-SQL, EF, EF.core).

Using @"User_Agent" simply causes a custom header to appear in the GET request.

User_agent: Foobar/1.0\r\n
User-Agent: Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_1_2 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Mobile/7D11\r\n

The above is what appears in the dissected HTTP packet, essentially confirming what Sfjava was quoting from that forum. It's interesting to note that "User-Agent" gets turned into "User_agent."

Using static cast would probably result in something like this:

// This does not prevent a possible type overflow
const char char_max = -1;

int i = 48;
char c = (i & char_max);

To prevent possible type overflow you could do this:

const char char_max = (char)(((unsigned char) char(-1)) / 2);

int i = 128;
char c = (i & char_max); // Would always result in positive signed values.

Where reinterpret_cast would probably just directly convert to char, without any cast safety. -> Never use reinterpret_cast if you can also use static_cast. If you're casting between classes, static_cast will also ensure, that the two types are matching (the object is a derivate of the cast type).

If your object a polymorphic type and you don't know which one it is, you should use dynamic_cast which will perform a type check at runtime and return nullptr if the types do not match.

IF you need const_cast you most likely did something wrong and should think about possible alternatives to fix const correctness in your code.

Try This:

sqlplus -s ${ORA_CONN_STR} <<EOF >/dev/null

Looks like you're a little bit confused about all that stuff.

operator is a built-in module providing a set of convenient operators. In two words operator.itemgetter(n) constructs a callable that assumes an iterable object (e.g. list, tuple, set) as input, and fetches the n-th element out of it.

So, you can't use key=a[x][1] there, because python has no idea what x is. Instead, you could use a lambda function (elem is just a variable name, no magic there):

a.sort(key=lambda elem: elem[1])

Or just an ordinary function:

def get_second_elem(iterable):
    return iterable[1]

a.sort(key=get_second_elem)

So, here's an important note: in python functions are first-class citizens, so you can pass them to other functions as a parameter.

Other questions:

1. Yes, you can reverse sort, just add reverse=True: a.sort(key=..., reverse=True)
2. To sort by more than one column you can use itemgetter with multiple indices: operator.itemgetter(1,2), or with lambda: lambda elem: (elem[1], elem[2]). This way, iterables are constructed on the fly for each item in list, which are than compared against each other in lexicographic(?) order (first elements compared, if equal - second elements compared, etc)
3. You can fetch value at [3,2] using a[2,1] (indices are zero-based). Using operator... It's possible, but not as clean as just indexing.

Refer to the documentation for details:

1. operator.itemgetter explained
2. Sorting list by custom key in Python

I have built semi-long shell scripts (300-500 lines) and Python code which does similar functionality. When many external commands are being executed, I find the shell is easier to use. Perl is also a good option when there is lots of text manipulation.

You can see a working example here:

http://codepen.io/anon/pen/GJzBxo

and

Same div, same text, different "spaces"

<div style="width: 500px; background: red"> [loooong text with spaces]</div>

You're getting a linker error, so your extern is working (the compiler compiled a.c without a problem), but when it went to link the object files together at the end it couldn't resolve your extern -- void doSomething(int); wasn't actually found anywhere. Did you mess up the extern? Make sure there's actually a doSomething defined in b.c that takes an int and returns void, and make sure you remembered to include b.c in your file list (i.e. you're doing something like gcc a.c b.c, not just gcc a.c)

A server-side solution is more compatible, until the "download" attribute is implemented in all the browsers.

One Python example could be a custom HTTP request handler for a filestore. The links that point to the filestore are generated like this:

http://www.myfilestore.com/filestore/13/130787e71/download_as/desiredName.pdf

Here is the code:

That works for me! Good luck!

The solution is actually a lot easier than any of the other suggestions:

std::wstring stemp = std::wstring(s.begin(), s.end());
LPCWSTR sw = stemp.c_str();

Best of all, it's platform independent.

I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).

1. I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.

   [Desktop Entry]
   Name=No name
   Encoding=UTF-8
   Version=1.0
   Exec=vncconfig -nowin
   X-GNOME-Autostart-enabled=true
   

2. Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.

3. Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.

A short one Liner of this is:

NotificationManagerCompat.from(context).cancel(NOTIFICATION_ID)

Or to cancel all notifications is:

NotificationManagerCompat.from(context).cancelAll()

You can use the extract() function
Drupal use it, in its theme() function.

Here it is a render function with a $variables argument.

function includeWithVariables($filePath, $variables = array(), $print = true)
{
    $output = NULL;
    if(file_exists($filePath)){
        // Extract the variables to a local namespace
        extract($variables);

        // Start output buffering
        ob_start();

        // Include the template file
        include $filePath;

        // End buffering and return its contents
        $output = ob_get_clean();
    }
    if ($print) {
        print $output;
    }
    return $output;

}

./index.php :

includeWithVariables('header.php', array('title' => 'Header Title'));

./header.php :

<h1><?php echo $title; ?></h1>

Simple one liner that you can use in ViewDidLoad()

//Change Color
    self.navigationController?.navigationBar.barTintColor = UIColor.red
//Change Text Color
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]

If you want to clear the div and remove all child nodes, you could put:

var mydiv = document.getElementById('FirstDiv');
while(mydiv.firstChild) {
  mydiv.removeChild(mydiv.firstChild);
}

You can't checkout a single directory of a repository because the entire repository is handled by the single .git folder in the root of the project instead of subversion's myriad of .svn directories.

The problem with working on plugins in a single repository is that making a commit to, e.g., mytheme will increment the revision number for myplugin, so even in subversion it is better to use separate repositories.

The subversion paradigm for sub-projects is svn:externals which translates somewhat to submodules in git (but not exactly in case you've used svn:externals before.)

Another solution to this old question is the new container string array, introduced in Matlab 2016b. From what I read in the official Matlab docs, this container resembles a cell-array and most of the array-related functions should work out of the box. For your case, new solution would be:

a=repmat('Some text', 10, 1);

This solution resembles a Rich C's solution applied to string array.

I got the same error when trying to decrypt the key from a different user account via su - <otherUser>. (Like jayhendren suggests in his answer)

In my case, this happened because there would normally start a graphical pinentry prompt so I could enter the password to decrypt the key, but the su -ed to user had no access to the (graphical) X-Window-System that was currently running.

The solution was to simply issue in that same console (as the user under which the X Server was currently running):

xhost +local:

Which gives other local users access to the currently running (local) X-Server. After that, the pinentry prompt appeared, I could enter the password to decrypt the key and it worked...

Of course you can also forward X over ssh connections. For this look into ssh's -X parameter (client side) and X11Forwarding yes (server side).

find . -type f -name '*php' -o -name '*js' -o -name '*html' |\
xargs grep -liE 'document\.cookie|setcookie'

Remember that your img is not really a DOM element but a javascript expression.

1. This is a JSX attribute expression. Put curly braces around the src string expression and it will work. See http://facebook.github.io/react/docs/jsx-in-depth.html#attribute-expressions

2. In javascript, the class attribute is reference using className. See the note in this section: http://facebook.github.io/react/docs/jsx-in-depth.html#react-composite-components

   /** @jsx React.DOM */
   
   var Hello = React.createClass({
       render: function() {
           return <div><img src={'http://placehold.it/400x20&text=slide1'} alt="boohoo" className="img-responsive"/><span>Hello {this.props.name}</span></div>;
       }
   });
   
   React.renderComponent(<Hello name="World" />, document.body);
   

Your code looks correct but sometimes google blocks an IP when you try to send a email from an unusual location. You can try to unblock it by visiting https://accounts.google.com/DisplayUnlockCaptcha from the IP and following the prompts.

Reference: https://support.google.com/accounts/answer/6009563

This situation calls for some preprocessor. Because if you write a function (static method) which picks the first not null value, it evaluates all items. It is problem if some items are method calls (may be time expensive method calls). And this methods are called even if any item before them is not null.

Some function like this

public static <T> T coalesce(T ...items) …

should be used but before compiling into byte code there should be a preprocessor which find usages of this „coalesce function“ and replaces it with construction like

a != null ? a : (b != null ? b : c)

Update 2014-09-02:

Thanks to Java 8 and Lambdas there is possibility to have true coalesce in Java! Including the crucial feature: particular expressions are evaluated only when needed – if earlier one is not null, then following ones are not evaluated (methods are not called, computation or disk/network operations are not done).

I wrote an article about it Java 8: coalesce – hledáme neNULLové hodnoty – (written in Czech, but I hope that code examples are understandable for everyone).

The documentation you linked actually has the answer in the link associated with the "Java class located out of the source root." Configure your source and test roots and it should work.

https://www.jetbrains.com/idea/webhelp/configuring-content-roots.html

Since you stated that these are tests you should probably go with them marked as Test Source Root instead of Source Root.

#include <stdio.h>

int main(){

    CvCapture *camera=cvCaptureFromFile("http://username:pass@cam_address/axis-cgi/mjpg/video.cgi?resolution=640x480&req_fps=30&.mjpg");
    if (camera==NULL)
        printf("camera is null\n");
    else
        printf("camera is not null");

    cvNamedWindow("img");
    while (cvWaitKey(10)!=atoi("q")){
        double t1=(double)cvGetTickCount();
        IplImage *img=cvQueryFrame(camera);
        double t2=(double)cvGetTickCount();
        printf("time: %gms  fps: %.2g\n",(t2-t1)/(cvGetTickFrequency()*1000.), 1000./((t2-t1)/(cvGetTickFrequency()*1000.)));
        cvShowImage("img",img);
    }
    cvReleaseCapture(&camera);
}

There is actually a very simple solution. Just set them both like this:

view.layer.borderWidth = 5

view.layer.borderColor = UIColor(red: 1, green: 1, blue: 1, alpha: 0.5).cgColor

view.backgroundColor = UIColor(red: 1, green: 1, blue: 1, alpha: 0.25).cgColor

int count = 0;
foreach (ListViewItem lvi in listView.Items)
{
    if(++count > 50) break;
}

delay() will not do the job. The problem with delay() is it's part of the animation system, and only applies to animation queues.

What if you want to wait before executing something outside of animation??

Use this:

window.setTimeout(function(){
                 // do whatever you want to do     
                  }, 600);

What happens?: In this scenario it waits 600 miliseconds before executing the code specified within the curly braces.

This helped me a great deal once I figured it out and hope it will help you as well!

IMPORTANT NOTICE: 'window.setTimeout' happens asynchronously. Keep that in mind when writing your code!

Below would be the best way to insert a row into pandas dataframe without sorting and reseting an index:

import pandas as pd

df = pd.DataFrame(columns=['a','b','c'])

def insert(df, row):
    insert_loc = df.index.max()

    if pd.isna(insert_loc):
        df.loc[0] = row
    else:
        df.loc[insert_loc + 1] = row

insert(df,[2,3,4])
insert(df,[8,9,0])
print(df)

const fs = require('fs');

try {
    fs.mkdirSync(path, { recursive: true });
} catch (error) {
    // this make script keep running, even when folder already exist
    console.log(error);
}

Assuming that you have access to SharePoint server, try the following. Some random thoughts and no specific order.

• Deploy the assembly to GAC or copy the dll to the bin folder of your web application
• Add the assembly info in your web.config assemblies section and in the safe controls section.
• If you are developing a web part, make sure to add its reference in the safe controls section of the web parts (although i don't think this is your problem)
• Signing the assembly with a strong name might help in some cases.
• If you have custom dependencies then you need to do the follow the same steps for all the dependencies (other than .net framework and SharePoint related)

Are you developing your SharePoint project (do you mean web part?) using visual studio? Are you referencing it in your SharePoint project? You need to give us more details on your development environment to be able to pinpoint the problem.

Most suggestions are assuming that you need to somehow destroy the last 20 commits, which is why it means "rewriting history", but you don't have to.

Just create a new branch from the commit #80 and work on that branch going forward. The other 20 commits will stay on the old orphaned branch.

If you absolutely want your new branch to have the same name, remember that branch are basically just labels. Just rename your old branch to something else, then create the new branch at commit #80 with the name you want.

In my opinion, deferreds/promises (as you have mentionned) is the way to go, rather than using timeouts.

Here is an example I have just written to demonstrate how you could do it using deferreds/promises.

Take some time to play around with deferreds. Once you really understand them, it becomes very easy to perform asynchronous tasks.

Hope this helps!

$(function(){
    function1().done(function(){
        // function1 is done, we can now call function2
        console.log('function1 is done!');

        function2().done(function(){
            //function2 is done
            console.log('function2 is done!');
        });
    });
});

function function1(){
    var dfrd1 = $.Deferred();
    var dfrd2= $.Deferred();

    setTimeout(function(){
        // doing async stuff
        console.log('task 1 in function1 is done!');
        dfrd1.resolve();
    }, 1000);

    setTimeout(function(){
        // doing more async stuff
        console.log('task 2 in function1 is done!');
        dfrd2.resolve();
    }, 750);

    return $.when(dfrd1, dfrd2).done(function(){
        console.log('both tasks in function1 are done');
        // Both asyncs tasks are done
    }).promise();
}

function function2(){
    var dfrd1 = $.Deferred();
    setTimeout(function(){
        // doing async stuff
        console.log('task 1 in function2 is done!');
        dfrd1.resolve();
    }, 2000);
    return dfrd1.promise();
}

This is very strange behavior for me. I'm surprised that no one thought of savepoints. In my code failing query was expected behavior:

from django.db import transaction
@transaction.commit_on_success
def update():
    skipped = 0
    for old_model in OldModel.objects.all():
        try:
            Model.objects.create(
                group_id=old_model.group_uuid,
                file_id=old_model.file_uuid,
            )
        except IntegrityError:
            skipped += 1
    return skipped

I have changed code this way to use savepoints:

from django.db import transaction
@transaction.commit_on_success
def update():
    skipped = 0
    sid = transaction.savepoint()
    for old_model in OldModel.objects.all():
        try:
            Model.objects.create(
                group_id=old_model.group_uuid,
                file_id=old_model.file_uuid,
            )
        except IntegrityError:
            skipped += 1
            transaction.savepoint_rollback(sid)
        else:
            transaction.savepoint_commit(sid)
    return skipped

Funny thing is Heroku actually uses AWS on the backend. It takes away all the overhead and does architecture management on EC2 for you. (Got that knowledge from a senior engineer at a Big Company during an Interview)

Make sure that your package is installed in your $GOPATH directory or already inside your workspace/package.

For example: if your $GOPATH = "c:\go", make sure that the package inside C:\Go\src\pkgName

I know it's only a Swift solution, but it could help someone.

I have globals.swift in every project with some code to ease my life and one of the things I always add are ScreenSize and hasNotch to easily detect phone type and dimensions:

struct ScreenSize {
  static let width = UIScreen.main.bounds.size.width
  static let height = UIScreen.main.bounds.size.height
}

var hasNotch: Bool {
  return UIApplication.shared.delegate?.window??.safeAreaInsets.top ?? 0 > 0
}

Then to use it:

if hasNotch {
  print("This executes on all phones with a notch")
}

You can use selectedIndex to retrieve the current selected option:

el = document.getElementById('elemId')
selectedText = el.options[el.selectedIndex].text

I was having the same problem. It seems that passing Me.ComboBox1.Value as an argument for the Vlookup function is causing the issue. What I did was assign this value to a double and then put it into the Vlookup function.

Dim x As Double
x = Me.ComboBox1.Value
Me.TextBox1.Value = Application.WorksheetFunction.VLookup(x, Worksheets("Sheet3").Range("Names"), 2, False) 

Or, for a shorter method, you can just convert the type within the Vlookup function using Cdbl(<Value>).

So it would end up being

Me.TextBox1.Value = Application.WorksheetFunction.VLookup(Cdbl(Me.ComboBox1.Value), Worksheets("Sheet3").Range("Names"), 2, False) 

Strange as it may sound, it works for me.

Hope this helps.

Well, there is an array type in recent Postgres versions (not 100% about PG 7.4). You can even index them, using a GIN or GIST index. The syntaxes are:

create table foo (
  bar  int[] default '{}'
);

select * from foo where bar && array[1] -- equivalent to bar && '{1}'::int[]

create index on foo using gin (bar); -- allows to use an index in the above query

But as the prior answer suggests, it will be better to normalize properly.

window.addEventListener("scroll",function(){
    window.lastScrollTime = new Date().getTime()
});
function is_scrolling() {
    return window.lastScrollTime && new Date().getTime() < window.lastScrollTime + 500
}

Change the 500 to the number of milliseconds after the last scroll event at which you consider the user to be "no longer scrolling".

(addEventListener is better than onScroll because the former can coexist nicely with any other code that uses onScroll.)

Try this:

$zip = new ZipArchive;
$zip->open('myzip.zip', ZipArchive::CREATE);
foreach (glob("target_folder/*") as $file) {
    $zip->addFile($file);
    if ($file != 'target_folder/important.txt') unlink($file);
}
$zip->close();

This will not zip recursively though.

If you only want to add Datapoints above the bars, you could easily do it with:

 for i in range(len(frequencies)): # your number of bars
    plt.text(x = x_values[i]-0.25, #takes your x values as horizontal positioning argument 
    y = y_values[i]+1, #takes your y values as vertical positioning argument 
    s = data_labels[i], # the labels you want to add to the data
    size = 9) # font size of datalabels

I agree with much that Manuel has said. In fact, his comments refer to this url...

http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4

... which states:

The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

However, for me it would come down to tool/framework support.

• What tools and frameworks do you expect your API users to be building their apps with?
• Do they have frameworks or components they can use that favour one method over the other?

If you get a clear idea of your users, and how they'll make use of your API, then that will help you decide. If you make the upload of files hard for your API users then they'll move away, of you'll spend a lot of time on supporting them.

Secondary to this would be the tool support YOU have for writing your API and how easy it is for your to accommodate one upload mechanism over the other.

I cobbled together this solution by scouring the Internet including

• Stack Overflow answers,
• MSDN articles,
• http://css-tricks.com/almanac/properties/t/transform/,
• http://caniuse.com/#search=transform,
• http://browserhacks.com/, and
• http://www.useragentman.com/IETransformsTranslator/.

This solution seems to work in all browsers including IE6+, using scale(-1,1) (a proper mirror) and appropriate filter/-ms-filter properties when necessary (IE6-8):

/* Cross-browser mirroring of content. Note that CSS pre-processors
  like Less cough on the media hack. 

  Microsoft recommends using BasicImage as a more efficent/faster form of
  mirroring, instead of FlipH or some kind of Matrix scaling/transform.
  @see http://msdn.microsoft.com/en-us/library/ms532972%28v=vs.85%29.aspx
  @see http://msdn.microsoft.com/en-us/library/ms532992%28v=vs.85%29.aspx
*/

/* IE8 only via hack: necessary because IE9+ will also interpret -ms-filter,
  and mirroring something that's already mirrored results in no net change! */
@media \0screen {
  .mirror {
    -ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(mirror=1)";
  }
}
.mirror {
  /* IE6 and 7 via hack */
  *filter: progid:DXImageTransform.Microsoft.BasicImage(mirror=1);
  /* Standards browsers, including IE9+ */
  -moz-transform: scale(-1,1);
  -ms-transform: scale(-1,1);
  -o-transform: scale(-1,1); /* Op 11.5 only */
  -webkit-transform: scale(-1,1);
  transform: scale(-1,1);
}

use checked : true, false property of the checkbox.

jQuery:

if($('input[type=checkbox]').is(':checked')) {
    $(this).prop('checked',true);
} else {
    $(this).prop('checked',false);
}

Lots of good answers but strange that no one has mentioned using a lambda function.
So if you have no arguments, things become pretty trivial:

def method1():
    return 'hello world'

def method2(methodToRun):
    result = methodToRun()
    return result

method2(method1)

But say you have one (or more) arguments in method1:

def method1(param):
    return 'hello ' + str(param)

def method2(methodToRun):
    result = methodToRun()
    return result

Then you can simply invoke method2 as method2(lambda: method1('world')).

method2(lambda: method1('world'))
>>> hello world
method2(lambda: method1('reader'))
>>> hello reader

I find this much cleaner than the other answers mentioned here.

XML:

<foo>
   <bar>
      <type foobar="1"/>
      <type foobar="2"/>
   </bar>
</foo>

Python code:

import xml.etree.cElementTree as ET

tree = ET.parse("foo.xml")
root = tree.getroot() 
root_tag = root.tag
print(root_tag) 

for form in root.findall("./bar/type"):
    x=(form.attrib)
    z=list(x)
    for i in z:
        print(x[i])

Output:

foo
1
2

tr can be more concise for removing characters than sed or awk, especially when you want to remove different characters from a string.

Removing double quotes:

echo '"Hi"' | tr -d \"
# Produces Hi without quotes

Removing different kinds of brackets:

echo '[{Hi}]' | tr -d {}[]
# Produces Hi without brackets

-d stands for "delete".

Because array access is defined in terms of pointers. a[i] is defined to mean *(a + i), which is commutative.

You can use the StringUtils.join() method of Apache Commons Lang:

String join = StringUtils.join(joinList, "+");

basename does remove the directory prefix of a path:

$ basename /usr/local/svn/repos/example
example
$ echo "/server/root/$(basename /usr/local/svn/repos/example)"
/server/root/example

ES6 is quite powerful in iterating through objects (strings, Array, Map, Set). Let's use a Spread Operator to solve this.

entry = prompt("Enter your name");
var count = [...entry];
console.log(count);

I was able to solve this problem by cleaning my build.

You can use the Python profiler cProfile to measure CPU time and additionally how much time is spent inside each function and how many times each function is called. This is very useful if you want to improve performance of your script without knowing where to start. This answer to another Stack Overflow question is pretty good. It's always good to have a look in the documentation too.

Here's an example how to profile a script using cProfile from a command line:

$ python -m cProfile euler048.py

1007 function calls in 0.061 CPU seconds

Ordered by: standard name
ncalls  tottime  percall  cumtime  percall filename:lineno(function)

    1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler objects}
    1    0.000    0.000    0.000    0.000 {range}
    1    0.003    0.003    0.003    0.003 {sum}

Here you go:

$( table ).delegate( '.tr_clone_add', 'click', function () {
    var thisRow = $( this ).closest( 'tr' )[0];
    $( thisRow ).clone().insertAfter( thisRow ).find( 'input:text' ).val( '' );
});

Live demo: http://jsfiddle.net/RhjxK/4/

Update: The new way of delegating events in jQuery is

$(table).on('click', '.tr_clone_add', function () { … });

Sprintf is what you are looking for.

Example

fmt.Sprintf("foo: %s", bar)

You can also see it in use in the Errors example as part of "A Tour of Go."

return fmt.Sprintf("at %v, %s", e.When, e.What)

There are differences with some exceptions, e.g. KeyboardInterrupt.

Reading PEP8:

A bare except: clause will catch SystemExit and KeyboardInterrupt exceptions, making it harder to interrupt a program with Control-C, and can disguise other problems. If you want to catch all exceptions that signal program errors, use except Exception: (bare except is equivalent to except BaseException:).

You can override the body scroll event with JavaScript, and reset the horizontal scroll to 0.

function bindEvent(e, eventName, callback) {
    if(e.addEventListener) // new browsers
        e.addEventListener(eventName, callback, false);
    else if(e.attachEvent) // IE
        e.attachEvent('on'+ eventName, callback);
};

bindEvent(document.body, 'scroll', function(e) {
    document.body.scrollLeft = 0;
});

I don't advise doing this because it limits functionality for users with small screens.

It works for me. Your data object is probably nil and, as rckoenes noted, the root object should be a (mutable) array. See this code:

NSString *jsonString = @"[{\"id\": \"1\", \"name\":\"Aaa\"}, {\"id\": \"2\", \"name\":\"Bbb\"}]";
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *e = nil;
NSMutableArray *json = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&e];
NSLog(@"%@", json);

(I had to escape the quotes in the JSON string with backslashes.)

Unfortunately none of the suggestions helped me, but after some more googling this

pip install aenum

solved it for me

i have same problem what i did i just downloaded 32-bit dll and added it to my bin folder this is solved my problem

You can either user STR_TO_DATE function and pass your own date parameters based on the format you have posted :

select * from hockey_stats where game_date 
  between STR_TO_DATE('11/3/2012 00:00:00', '%c/%e/%Y %H:%i:%s')
  and STR_TO_DATE('11/5/2012 23:59:00', '%c/%e/%Y %H:%i:%s') 
order by game_date desc;

Or just use the format which MySQL handles dates YYYY:MM:DD HH:mm:SS and have the query as

select * from hockey_stats where game_date between '2012-03-11 00:00:00' and'2012-05-11 23:59:00' order by game_date desc;

I think using dtype where there is a name row is confusing the routine. Try

>>> r = np.genfromtxt(fname, delimiter=',', names=True)
>>> r
array([[  6.11882430e+02,   9.08956010e+03,   5.13300000e+03,
          8.64075140e+02,   1.71537476e+03,   7.65227770e+02,
          1.29111196e+12],
       [  6.11882430e+02,   9.08956010e+03,   5.13300000e+03,

       [  6.11882430e+02,   9.08956010e+03,   5.13300000e+03,
          8.64075140e+02,   1.71537476e+03,   7.65227770e+02,

Use wine - it has IE6 with Gecko support built into it. More information here.

Try this:

Posting a new answer since it is (almost) 2020.

The Android Emulator still only supports HAXM or WHPX on windows. And you may even call it a day already with the latter.

But if you don't like it, there is now work in progress AMD-V support for the former by one of the PS4 emulator developers: https://github.com/jarveson/haxm/tree/svm

This could be the possible way in which you can directly use LINQ extension methods to check the in clause

var result = _db.Companies.Where(c => _db.CurrentSessionVariableDetails.Select(s => s.CompanyId).Contains(c.Id)).ToList();

I assume you're asking for the full HTML string. If that's the case, something like this will do the trick:

$('<div>').append($('#item-of-interest').clone()).html(); 

This is explained in more depth here, but essentially you make a new node to wrap the item of interest, do the manipulations, remove it, and grab the HTML.

If you're just after a string representation, then go with new String(obj).

Update

I wrote the original answer in 2009. As of 2014, most major browsers now support outerHTML as a native property (see, for example, Firefox and Internet Explorer), so you can do:

$('#item-of-interest').prop('outerHTML');

You can alternatively just run pip3 install packagename instead of pip,

You can pass the value to the function using this.value, where this points to the button

<input type="button" value="mybutton1" onclick="dosomething(this.value)">

And then access that value in the function

function dosomething(val){
  console.log(val);
}

  panel: {
    // ios
    backgroundColor: '#03A9F4',
    alignItems: 'center', 
    shadowOffset: {width: 0, height: 13}, 
    shadowOpacity: 0.3,
    shadowRadius: 6,

    // android (Android +5.0)
    elevation: 3,
  }

or you can use react-native-shadow for android

Regarding the 64-bit system wanting 32-bit support. I don't find it so bizarre:

Although deployed to a 64-bit system, this doesn't mean all the referenced assemblies are necessarily 64-bit Crystal Reports assemblies. Further to that, the Crystal Reports assemblies are largely just wrappers to a collection of legacy DLLs upon which they are based. Many 32-bit DLLs are required by the primarily referenced assembly. The error message "can not load the assembly" involves these DLLs as well. To see visually what those are, go to www.dependencywalker.com and run 'Depends' on the assembly in question, directly on that IIS server.

public boolean isInternetWorking(){
    try {
        int timeOut = 5000;
        Socket socket = new Socket();
        SocketAddress socketAddress = new InetSocketAddress("8.8.8.8",53);
        socket.connect(socketAddress,timeOut);
        socket.close();
        return true;
    } catch (IOException e) {
        //silent
    }
    return false;
}

This is a really unclear and unhelpful error message. After much trial and error I found that LocalDateTime will give the above error if you do not attempt to parse a time. By using LocalDate instead, it works without erroring.

This is poorly documented and the related exception is very unhelpful.

I think this method produces very good results:

You can add it to your shell configuration file, e.g. $HOME/.bashrc or more globally in /etc/environment. After adding these lines the changes won't reflect instantly in GUI based system's you have to exit the terminal or create a new one and in server logout the session and login to reflect these changes.

try this

float rateX =  (float)jpDisplayImagen.getWidth()/(float)img.getWidth();
float rateY = (float)jpDisplayImagen.getHeight()/(float)img.getHeight();
if (rateX>rateY){
    int W=(int)(img.getWidth()*rateY);
    int H=(int)(img.getHeight()*rateY);
    jpDisplayImagen.getGraphics().drawImage(img, 0, 0,W,H, null);
}
else{
    int W=(int)(img.getWidth()*rateX);
    int H=(int)(img.getHeight()*rateX);
    jpDisplayImagen.getGraphics().drawImage(img, 0, 0,W,H, null);
}

As an alternative to cut- or awk-based one-liners, you could use the specialized csvtool aka ocaml-csv:

$ csvtool -t ',' col "$index" - < csvfile | grep "$value"

According to the docs, it handles escaping, quoting, etc.

All executable files from Visual Studio should be located in the debug folder of your project, e.g:

Visual Studio Directory: c:\users\me\documents\visual studio

Then the project which was called 'hello world' would be in the directory:

c:\users\me\documents\visual studio\hello world

And your exe would be located in:

c:\users\me\documents\visual studio\hello world\Debug\hello world.exe

Note the exe being named the same as the project.

Otherwise, you could publish it to a specified folder of your choice which comes with an installation, which would be good if you wanted to distribute it quickly

EDIT:

Everytime you build your project in VS, the exe is updated with the new one according to the code (as long as it builds without errors). When you publish it, you can choose the location, aswell as other factors, and the setup exe will be in that location, aswell as some manifest files and other files about the project.

Following up on David's answer...

Using SHOW SLAVE STATUS\G will give human-readable output.

You can simply go to Menu > All Programs > Visual Studio 2013. Select the folder link "Visual Studio Tools". This will open the folder. There is bunch of shortcuts for command prompt which you can use. They worked perfectly for me.

I think the trick here might be there are different versions for different processors, hence they put them all together.

Depends on your use case but to summarise the difference:

1. ng-if will remove elements from DOM. This means that all your handlers or anything else attached to those elements will be lost. For example, if you bound a click handler to one of child elements, when ng-if evaluates to false, that element will be removed from DOM and your click handler will not work any more, even after ng-if later evaluates to true and displays the element. You will need to reattach the handler.
2. ng-show/ng-hide does not remove the elements from DOM. It uses CSS styles to hide/show elements (note: you might need to add your own classes). This way your handlers that were attached to children will not be lost.
3. ng-if creates a child scope while ng-show/ng-hide does not

Elements that are not in the DOM have less performance impact and your web app might appear to be faster when using ng-if compared to ng-show/ng-hide. In my experience, the difference is negligible. Animations are possible when using both ng-show/ng-hide and ng-if, with examples for both in the Angular documentation.

Ultimately, the question you need to answer is whether you can remove element from DOM or not?

var Text = File.ReadAllLines("Path"); foreach (var i in Text) {    var SplitText = i.Split().Where(x=> x.Lenght>1).ToList();    //@Array1 add SplitText[0]    //@Array2 add SpliteText[1]   }  

Easy CSS properties can do the trick. The following is for a three-line ellipsis.

display: -webkit-box;
-webkit-line-clamp: 3;
-webkit-box-orient: vertical;
overflow: hidden;
text-overflow: ellipsis;

You can also use Url.Action for the path instead like so:

$.ajax({
        url: "@Url.Action("Holiday", "Calendar", new { area = "", year= (val * 1) + 1 })",                
        type: "GET",           
        success: function (partialViewResult) {            
            $("#refTable").html(partialViewResult);
        }
    });

Personally, I think the simplest approach to do an http post and get the response is to use the WebClient class. This class nicely abstracts the details. There's even a full code example in the MSDN documentation.

http://msdn.microsoft.com/en-us/library/system.net.webclient(VS.80).aspx

In your case, you want the UploadData() method. (Again, a code sample is included in the documentation)

http://msdn.microsoft.com/en-us/library/tdbbwh0a(VS.80).aspx

UploadString() will probably work as well, and it abstracts it away one more level.

http://msdn.microsoft.com/en-us/library/system.net.webclient.uploadstring(VS.80).aspx

May be this helps some one who are looking for multiple date formats one after the other by willingly or unexpectedly. Please find the code: I am using moment.js format function on a current date as (today is 29-06-2020) var startDate = moment(new Date()).format('MM/DD/YY'); Result: 06/28/20

what happening is it retains only the year part :20 as "06/28/20", after If I run the statement : new Date(startDate) The result is "Mon Jun 28 1920 00:00:00 GMT+0530 (India Standard Time)",

Then, when I use another format on "06/28/20": startDate = moment(startDate ).format('MM-DD-YYYY'); Result: 06-28-1920, in google chrome and firefox browsers it gives correct date on second attempt as: 06-28-2020. But in IE it is having issues, from this I understood we can apply one dateformat on the given date, If we want second date format, it should be apply on the fresh date not on the first date format result. And also observe that for first time applying 'MM-DD-YYYY' and next 'MM-DD-YY' is working in IE. For clear understanding please find my question in the link: Date went wrong when using Momentjs date format in IE 11

 <!doctype html>
 <meta http-equiv="X-UA-Compatible" content="IE=Edge">

This makes each version of IE use its standard mode, so IE 9 will use IE 9 standards mode. (If instead you wanted newer versions of IE to also specifically use IE 9 standards mode, you would replace Edge by 9. But it is difficult to see why you would want that.)

For explanations, see http://hsivonen.iki.fi/doctype/#ie8 (it looks rather messy, but that’s because IE is messy in its behaviors).

If you are using xampp in windows then please do following

1. Open XAMPP control panel.
2. Click on CONFIG button.
3. Go to PHP (php.ini) option.

Find short_open_tag using ctrl+f utility

You will found ;short_open_tag

kindly remove the semicolon (;) from line.

and keep it as short_open_tag = on

Finally, restart your Apache server

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

For Swift 3.0:

button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)

where "boldSystemFont" and "16" can be replaced with your custom font and size.

If you use Kotlin, you can add an extension method to Image in the same manner Sri Harsha Chilakapati suggests.

fun Image.toBufferedImage(): BufferedImage {
    if (this is BufferedImage) {
        return this
    }
    val bufferedImage = BufferedImage(this.getWidth(null), this.getHeight(null), BufferedImage.TYPE_INT_ARGB)

    val graphics2D = bufferedImage.createGraphics()
    graphics2D.drawImage(this, 0, 0, null)
    graphics2D.dispose()

    return bufferedImage
}

And use it like this:

myImage.toBufferedImage()

This worked for me. First add this android:windowSoftInputMode="stateHidden" in your android manifest file, under your activity. like below:

<activity ... android:windowSoftInputMode="stateHidden">

Then on onCreate method of youractivity, add the foloowing code:

EditText editText = (EditText)findViewById(R.id.edit_text);
edit_text.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        v.onTouchEvent(event);
        InputMethodManager inputMethod = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        if (inputMethod!= null) {
            inputMethod.hideSoftInputFromWindow(v.getWindowToken(), 0);
        }                
        return true;
    }
});

Then if you want the pointer to be visible add this on your xml android:textIsSelectable="true".

This will make the pointer visible. In this way the keyboard will not popup when your activity starts and also will be hidden when you click on the edittext.

I dont know why all these complicated answers are on here but this is what I would do

where pdate >= CURRENT_TIMESTAMP -30

OR WHERE CAST(PDATE AS DATE) >= GETDATE() -30

Using the ${#VAR} syntax will calculate the number of characters in a variable.

Generic:

ALTER TABLE table_name 
DROP COLUMN column1,column2,column3;

E.g:

ALTER TABLE Student 
DROP COLUMN Name, Number, City;

You say that if int(splitLine[0]) > int(lastUnix): is causing the trouble, but you don't actually show anything which suggests that. I think this line is the problem instead:

print 'Pulled', + stock

Do you see why this line could cause that error message? You want either

>>> stock = "AAAA"
>>> print 'Pulled', stock
Pulled AAAA

or

>>> print 'Pulled ' + stock
Pulled AAAA

not

>>> print 'Pulled', + stock
PulledTraceback (most recent call last):
  File "<ipython-input-5-7c26bb268609>", line 1, in <module>
    print 'Pulled', + stock
TypeError: bad operand type for unary +: 'str'

You're asking Python to apply the + symbol to a string like +23 makes a positive 23, and she's objecting.

The link with a relative path can be created using the mklink command on windows command line.

mklink /d \MyDocs \Users\User1\Documents

This might be the best way to create link because apparently, the behaviour of shortcut can be different perhaps based on the way they are created (UI vs mklink command). I observed some strange behavior with how the shortcuts behave when I change the root folder.

• There is a weird behaviour on Windows 7 that I tested. Sometimes the the link still just works when the root folder of target is changed (the shortcut properties automatically update to reflect the changed path!). The "start in" field updates automatically as well if it was there.
• I also noticed that one link doesn't work the first time I change the root path (properties shows old) but it works after the 2nd and everytime after that. The link properties get updated as result of the first run!
• I also noticed at least for two link, it doesn't update the path and no longer works.
• From link properties, there is no difference in format of any fields yet the behaviour is different.

Improving upon the answer of @Arjen de Mooij a bit by making the AllowJsonGetAttribute applicable to mvc-controllers (not just individual action-methods):

using System.Web.Mvc;
public sealed class AllowJsonGetAttribute : ActionFilterAttribute, IActionFilter
{
    void IActionFilter.OnActionExecuted(ActionExecutedContext context)
    {
        var jsonResult = context.Result as JsonResult;
        if (jsonResult == null) return;

        jsonResult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }

    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        var jsonResult = filterContext.Result as JsonResult;
        if (jsonResult == null) return;

        jsonResult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
        base.OnResultExecuting(filterContext);
    }
}

I also got the similar error.

Problem :

Solution :

Main root cause for this issue ismultiDex is not enabled. So in the Project/android/app/build.gradle, enable the multiDex

For further information refer the documentation: https://developer.android.com/studio/build/multidex#mdex-gradle

To expand on Ryan's answer, when you are declaring variables (using Dim) you can cheat a little bit by using the predictive text feature in the VBE, as in the image below.

If it shows up in that list, then you can assign an object of that type to a variable. So not just a Worksheet, as Ryan pointed out, but also a Chart, Range, Workbook, Series and on and on.

You set that variable equal to the object you want to manipulate and then you can call methods, pass it to functions, etc, just like Ryan pointed out for this example. You might run into a couple snags when it comes to collections vs objects (Chart or Charts, Range or Ranges, etc) but with trial and error you'll get it for sure.

With yield you can easily describe the breakpoints between multiple tasks in a single function. That's all, there is nothing special about it.

$closure = function ($injected1, $injected2, ...){
    $returned = array();
    //task1 on $injected1
    $returned[] = $returned1;
//I need a breakpoint here!!!!!!!!!!!!!!!!!!!!!!!!!
    //task2 on $injected2
    $returned[] = $returned2;
    //...
    return $returned;
};
$returned = $closure($injected1, $injected2, ...);

If task1 and task2 are highly related, but you need a breakpoint between them to do something else:

• free memory between processing database rows
• run other tasks which provide dependency to the next task, but which are unrelated by understanding the current code
• doing async calls and wait for the results
• and so on ...

then generators are the best solution, because you don't have to split up your code into many closures or mix it with other code, or use callbacks, etc... You just use yield to add a breakpoint, and you can continue from that breakpoint if you are ready.

Add breakpoint without generators:

$closure1 = function ($injected1){
    //task1 on $injected1
    return $returned1;
};
$closure2 = function ($injected2){
    //task2 on $injected2
    return $returned1;
};
//...
$returned1 = $closure1($injected1);
//breakpoint between task1 and task2
$returned2 = $closure2($injected2);
//...

Add breakpoint with generators

$closure = function (){
    $injected1 = yield;
    //task1 on $injected1
    $injected2 = (yield($returned1));
    //task2 on $injected2
    $injected3 = (yield($returned2));
    //...
    yield($returnedN);
};
$generator = $closure();
$returned1 = $generator->send($injected1);
//breakpoint between task1 and task2
$returned2 = $generator->send($injected2);

$returnedN = $generator->send($injectedN);

note: It is easy to make mistake with generators, so always write unit tests before you implement them! note2: Using generators in an infinite loop is like writing a closure which has infinite length...

AutoResetEvent maintains a boolean variable in memory. If the boolean variable is false then it blocks the thread and if the boolean variable is true it unblocks the thread.

When we instantiate an AutoResetEvent object, we pass the default value of boolean value in the constructor. Below is the syntax of instantiate an AutoResetEvent object.

AutoResetEvent autoResetEvent = new AutoResetEvent(false);

WaitOne method

This method blocks the current thread and wait for the signal by other thread. WaitOne method puts the current thread into a Sleep thread state. WaitOne method returns true if it receives the signal else returns false.

autoResetEvent.WaitOne();

Second overload of WaitOne method wait for the specified number of seconds. If it does not get any signal thread continues its work.

static void ThreadMethod()
{
    while(!autoResetEvent.WaitOne(TimeSpan.FromSeconds(2)))
    {
        Console.WriteLine("Continue");
        Thread.Sleep(TimeSpan.FromSeconds(1));
    }

    Console.WriteLine("Thread got signal");
}

We called WaitOne method by passing the 2 seconds as arguments. In the while loop, it wait for the signal for 2 seconds then it continues its work. When the thread got the signal WaitOne returns true and exits the loop and print the "Thread got signal".

Set method

AutoResetEvent Set method sent the signal to the waiting thread to proceed its work. Below is the syntax of calling Set method.

autoResetEvent.Set();

ManualResetEvent maintains a boolean variable in memory. When the boolean variable is false then it blocks all threads and when the boolean variable is true it unblocks all threads.

When we instantiate a ManualResetEvent, we initialize it with default boolean value.

ManualResetEvent manualResetEvent = new ManualResetEvent(false);

In the above code, we initialize the ManualResetEvent with false value, that means all the threads which calls the WaitOne method will block until some thread calls the Set() method.

If we initialize ManualResetEvent with true value, all the threads which calls the WaitOne method will not block and free to proceed further.

WaitOne Method

This method blocks the current thread and wait for the signal by other thread. It returns true if its receives a signal else returns false.

Below is the syntax of calling WaitOne method.

manualResetEvent.WaitOne();

In the second overload of WaitOne method, we can specify the time interval till the current thread wait for the signal. If within time internal, it does not receives a signal it returns false and goes into the next line of method.

Below is the syntax of calling WaitOne method with time interval.

bool isSignalled = manualResetEvent.WaitOne(TimeSpan.FromSeconds(5));

We have specify 5 seconds into the WaitOne method. If the manualResetEvent object does not receives a signal between 5 seconds, it set the isSignalled variable to false.

Set Method

This method is used for sending the signal to all waiting threads. Set() Method set the ManualResetEvent object boolean variable to true. All the waiting threads are unblocked and proceed further.

Below is the syntax of calling Set() method.

manualResetEvent.Set();

Reset Method

Once we call the Set() method on the ManualResetEvent object, its boolean remains true. To reset the value we can use Reset() method. Reset method change the boolean value to false.

Below is the syntax of calling Reset method.

manualResetEvent.Reset();

We must immediately call Reset method after calling Set method if we want to send signal to threads multiple times.

204 No Content

The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

According to the RFC part for the status code 204, it seems to me a valid choice for a GET request.

A 404 Not Found, 200 OK with empty body and 204 No Content have completely different meaning, sometimes we can't use proper status code but bend the rules and they will come back to bite you one day or later. So, if you can use proper status code, use it!

I think the choice of GET or POST is very personal as both of them will do the work but I would recommend you to keep a POST instead of a GET, for two reasons:

• You want the other part (the servlet if I understand correctly) to perform an action not retrieve some data from it.
• By default GET requests are cacheable if there are no parameters present in the URL, a POST is not.

I've tested this, it all works. So this method processInput will just ask the user to type something in. it will return a string that has no extra spaces internally, nor extra spaces at the begining or the end. Hope this helps. (also put a heap of commenting in to make it simple to understand).

you can see how to implement it in the main() at the bottom

#include <string>
#include <iostream>

string processInput() {
  char inputChar[256];
  string output = "";
  int outputLength = 0;
  bool space = false;
  // user inputs a string.. well a char array
  cin.getline(inputChar,256);
  output = inputChar;
       string outputToLower = "";
  // put characters to lower and reduce spaces
  for(int i = 0; i < output.length(); i++){
    // if it's caps put it to lowercase
    output[i] = tolower(output[i]);
    // make sure we do not include tabs or line returns or weird symbol for null entry array thingy
    if (output[i] != '\t' && output[i] != '\n' && output[i] != 'Ì') {
      if (space) {
        // if the previous space was a space but this one is not, then space now is false and add char
        if (output[i] != ' ') {
          space = false;
          // add the char
          outputToLower+=output[i];
        }
      } else {
        // if space is false, make it true if the char is a space
        if (output[i] == ' ') {
          space = true;
        }
        // add the char
        outputToLower+=output[i];
      }
    }
  }
  // trim leading and tailing space
  string trimmedOutput = "";
  for(int i = 0; i < outputToLower.length(); i++){
    // if it's the last character and it's not a space, then add it
    // if it's the first character and it's not a space, then add it
    // if it's not the first or the last then add it
    if (i == outputToLower.length() - 1 && outputToLower[i] != ' ' || 
      i == 0 && outputToLower[i] != ' ' || 
      i > 0 && i < outputToLower.length() - 1) {
      trimmedOutput += outputToLower[i];
    } 
  }
  // return
  output = trimmedOutput;
  return output;
}

int main() {
  cout << "Username: ";
  string userName = processInput();
  cout << "\nModified Input = " << userName << endl;
}

While most people will tell you to just use multiple repositories, I feel it's worth mentioning there are other solutions.

Solution 1

A single repository can contain multiple independent branches, called orphan branches. Orphan branches are completely separate from each other; they do not share histories.

git checkout --orphan BRANCHNAME

This creates a new branch, unrelated to your current branch. Each project should be in its own orphaned branch.

Now for whatever reason, git needs a bit of cleanup after an orphan checkout.

rm .git/index
rm -r *

Make sure everything is committed before deleting

Once the orphan branch is clean, you can use it normally.

Solution 2

Avoid all the hassle of orphan branches. Create two independent repositories, and push them to the same remote. Just use different branch names for each repo.

# repo 1
git push origin master:master-1

# repo 2
git push origin master:master-2

In case this helps anyone :

static bool myFunction(Node& p1, Node& p2) {}
priority_queue <Node, vector<Node>, function<bool(Node&, Node&)>> pq1(myFunction);

Having the braces right from the first moment should help to prevent you from ever having to debug this:

if (statement)
     do this;
else
     do this;
     do that;

I found this here:

On windows (win xp), the parent process will not finish until the longtask.py has finished its work. It is not what you want in CGI-script. The problem is not specific to Python, in PHP community the problems are the same.

The solution is to pass DETACHED_PROCESS Process Creation Flag to the underlying CreateProcess function in win API. If you happen to have installed pywin32 you can import the flag from the win32process module, otherwise you should define it yourself:

DETACHED_PROCESS = 0x00000008

pid = subprocess.Popen([sys.executable, "longtask.py"],
                       creationflags=DETACHED_PROCESS).pid

Your model properties don't have to be 'auto properties' Even though that is easier. And the DefaultValue attribute is really only informative metadata The answer accepted here is one alternative to the constructor approach.

public class Track
{

    private const int DEFAULT_LENGTH = 400;
    private int _length = DEFAULT_LENGTH;
    [DefaultValue(DEFAULT_LENGTH)]
    public int LengthInMeters {
        get { return _length; }
        set { _length = value; }
    }
}

vs.

public class Track
{
    public Track()
    {
        LengthInMeters = 400;   
    }

    public int LengthInMeters { get; set; }        
}

This will only work for applications creating and consuming data using this specific class. Usually this isn't a problem if data access code is centralized. To update the value across all applications you need to configure the datasource to set a default value. Devi's answer shows how it can be done using migrations, sql, or whatever language your data source speaks.

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

For me it was a simple matter of being sure to include the JDK installation (I'd only had the JRE). My R CMD javareconf output was looking like:

Got to the question but could not figure out how to print it from externally-loaded mongo. So:

This works is for console: and is prefered in console, but does not work in external mongo-loaded javascript:

db.quizes.find().pretty()

This works in external mongo-loaded javscript:

db.quizes.find().forEach(printjson)

def send_email(user, pwd, recipient, subject, body):
    import smtplib

    FROM = user
    TO = recipient if isinstance(recipient, list) else [recipient]
    SUBJECT = subject
    TEXT = body

    # Prepare actual message
    message = """From: %s\nTo: %s\nSubject: %s\n\n%s
    """ % (FROM, ", ".join(TO), SUBJECT, TEXT)
    try:
        server = smtplib.SMTP("smtp.gmail.com", 587)
        server.ehlo()
        server.starttls()
        server.login(user, pwd)
        server.sendmail(FROM, TO, message)
        server.close()
        print 'successfully sent the mail'
    except:
        print "failed to send mail"

if you want to use Port 465 you have to create an SMTP_SSL object:

# SMTP_SSL Example
server_ssl = smtplib.SMTP_SSL("smtp.gmail.com", 465)
server_ssl.ehlo() # optional, called by login()
server_ssl.login(gmail_user, gmail_pwd)  
# ssl server doesn't support or need tls, so don't call server_ssl.starttls() 
server_ssl.sendmail(FROM, TO, message)
#server_ssl.quit()
server_ssl.close()
print 'successfully sent the mail'

Use MySQL FIND_IN_SET function:

  SELECT * 
    FROM table_name 
   WHERE id IN (..,..,..,..) 
ORDER BY FIND_IN_SET (coloumn_name, .., .., ..);

Position the cursor inside the class, then press ALT + Ins and select Getters and Setters from the contextual menu.

To add a very important note on what Mark S. has mentioned in his post. In the specific SQL Script that has been mentioned in the question you can NEVER mention two different file groups for storing your data rows and the index data structure.

The reason why is due to the fact that the index being created in this case is a clustered Index on your primary key column. The clustered index data and the data rows of your table can NEVER be on different file groups.

So in case you have two file groups on your database e.g. PRIMARY and SECONDARY then below mentioned script will store your row data and clustered index data both on PRIMARY file group itself even though I've mentioned a different file group ([SECONDARY]) for the table data. More interestingly the script runs successfully as well (when I was expecting it to give an error as I had given two different file groups :P). SQL Server does the trick behind the scene silently and smartly.

CREATE TABLE [dbo].[be_Categories](
    [CategoryID] [uniqueidentifier] ROWGUIDCOL  NOT NULL CONSTRAINT [DF_be_Categories_CategoryID]  DEFAULT (newid()),
    [CategoryName] [nvarchar](50) NULL,
    [Description] [nvarchar](200) NULL,
    [ParentID] [uniqueidentifier] NULL,
 CONSTRAINT [PK_be_Categories] PRIMARY KEY CLUSTERED 
(
    [CategoryID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [SECONDARY]
GO

NOTE: Your index can reside on a different file group ONLY if the index being created is non-clustered in nature.

The below script which creates a non-clustered index will get created on [SECONDARY] file group instead when the table data already resides on [PRIMARY] file group:

CREATE NONCLUSTERED INDEX [IX_Categories] ON [dbo].[be_Categories]
(
    [CategoryName] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [Secondary]
GO

You can get more information on how storing non-clustered indexes on a different file group can help your queries perform better. Here is one such link.

The API can't be loaded after the document has finished loading by default, you'll need to load it asynchronous.

  map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
  directionsDisplay.setMap(map);

For more details take a look at: https://stackoverflow.com/questions/14184956/async-google-maps-api-v3-undefined-is-not-a-function/14185834#14185834

Example: http://jsfiddle.net/doktormolle/zJ5em/

That's the other way around. You should write:

$("table.planning_grid").on({
    mouseenter: function() {
        // Handle mouseenter...
    },
    mouseleave: function() {
        // Handle mouseleave...
    },
    click: function() {
        // Handle click...
    }
}, "td");

Another way to look at it is to consider git rebase master as:

Rebase the current branch on top of master

Here , 'master' is the upstream branch, and that explain why, during a rebase, ours and theirs are reversed.

Selects are slow and unnescsaary. The following code will be far faster:

Sub CopyRowsAcross() 
Dim i As Integer 
Dim ws1 As Worksheet: Set ws1 = ThisWorkbook.Sheets("Sheet1") 
Dim ws2 As Worksheet: Set ws2 = ThisWorkbook.Sheets("Sheet2") 

For i = 2 To ws1.Range("B65536").End(xlUp).Row 
    If ws1.Cells(i, 2) = "Your Critera" Then ws1.Rows(i).Copy ws2.Rows(ws2.Cells(ws2.Rows.Count, 2).End(xlUp).Row + 1) 
Next i 
End Sub 

   var form = $('#job-request-form')[0];
        var formData = new FormData(form);
        event.preventDefault();
        $.ajax({
            url: "/send_resume/", // the endpoint
            type: "POST", // http method
            processData: false,
            contentType: false,
            data: formData,

It worked for me! just set processData and contentType False.

Again, don't need the comparator for Arrays.binarySearch(Object[] a, Object key) so long as the types of objects are comparable, but with lambda expressions this is now way easier.

Simply replace the comparator with the method reference: String::compareTo

E.g.:

Arrays.binarySearch(someStringArray, "The String to find.", String::compareTo);

You could also use

Arrays.binarySearch(someStringArray, "The String to find.", (a,b) -> a.compareTo(b));

but even before lambdas, there were always anonymous classes:

Arrays.binarySearch(
                someStringArray,
                "The String to find.",
                new Comparator<String>() {
                    @Override
                    public int compare(String o1, String o2) {
                        return o1.compareTo(o2);
                    }
                });

You can join a table to itself as many times as you require, it is called a self join.

An alias is assigned to each instance of the table (as in the example below) to differentiate one from another.

SELECT a.SelfJoinTableID
FROM   dbo.SelfJoinTable a
       INNER JOIN dbo.SelfJoinTable b
         ON a.SelfJoinTableID = b.SelfJoinTableID
       INNER JOIN dbo.SelfJoinTable c
         ON a.SelfJoinTableID = c.SelfJoinTableID
WHERE  a.Status = 'Status to filter a'
       AND b.Status = 'Status to filter b'
       AND c.Status = 'Status to filter c' 

There are two different ways you can add/override spring properties on the command line.

Option 1: Java System Properties (VM Arguments)

It's important that the -D parameters are before your application.jar otherwise they are not recognized.

java -jar -Dspring.profiles.active=prod application.jar

Option 2: Program arguments

java -jar application.jar --spring.profiles.active=prod --spring.config.location=c:\config

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

Once gdb starts, you can run the program using "r args".

So if you are running your code by:

$ executablefile arg1 arg2 arg3 

Debug it on gdb by:

$ gdb executablefile  
(gdb) r arg1 arg2 arg3

You can lowercase the value and the passed parameter :

SELECT * FROM `table` WHERE LOWER(`Value`) = LOWER("IAreSavage")

Another (better) way would be to use the COLLATE operator as said in the documentation

Of course src="@/assets/images/x.jpg works, but better way is: src="~assets/images/x.jpg

You can use StringUtils.isEmpty(), It will result true if the string is either null or empty.

 String str1 = "";
 String str2 = null;

 if(StringUtils.isEmpty(str)){
     System.out.println("str1 is null or empty");
 }

 if(StringUtils.isEmpty(str2)){
     System.out.println("str2 is null or empty");
 }

will result in

str1 is null or empty

str2 is null or empty

You can easily iterate you collection. The example below is for the special Access TempVars collection, but works with any regular collection.

Dim tv As Long
For tv = 0 To TempVars.Count - 1
    Debug.Print TempVars(tv).Name, TempVars(tv).Value
Next tv

Right-click on the table in SSMS, 'Design' it, and click on the id column. In the properties, set the identity to be seeded @ e.g. 1 and to have increment of 1 - save and you're done.

git remote show origin

Replace 'origin' with whatever the name of your remote is.

Thanks to AddRange:

Example:

public class Person
{ 
    private string Name;
    private string FirstName;

    public Person(string name, string firstname) => (Name, FirstName) = (name, firstname);
}

To add multiple Person to a List<>:

List<Person> listofPersons = new List<Person>();
listofPersons.AddRange(new List<Person>
{
    new Person("John1", "Doe" ),
    new Person("John2", "Doe" ),
    new Person("John3", "Doe" ),
 });

Didn't see this posted here, but you can do it with Pyside and Qt now that Qt works on Android thanks to Necessitas.

Just a small one to add, you should use the img tag if you want users to be able to 'right click' and 'save-image'/'save-picture', so if you intend to provide the image as a resource for others.

Using background image will (as far as I'm aware on most browsers) disable the option to save the image directly.

Simplest method when not using an emulator

$ adb shell
$ run-as your.package.name
$ chmod 777 databases
$ chmod 777 databases/database_name
$ exit
$ cp /data/data/your.package.name/databases/database_name /sdcard
$ run-as your.package.name # Optional
$ chmod 660 databases/database_name # Optional
$ chmod 660 databases # Optional
$ exit # Optional
$ exit
$ adb pull /sdcard/database_name

Caveats:

I haven't tested this in a while. It may not work on API>=25. If the cp command isn't working for you try one of the following instead:

# Pick a writeable directory <dir> other than /sdcard
$ cp /data/data/your.package.name/databases/database_name <dir>

# Exit and pull from the terminal on your PC
$ exit
$ adb pull /data/data/your.package.name/databases/database_name

Explanation:

The first block configures the permissions of your database to be readable. This leverages run-as which allows you to impersonate your package's user to make the change.

$ adb shell
$ run-as your.package.name
$ chmod 777 databases
$ chmod 777 databases/database_name
$ exit # Closes the shell started with run-as

Next we copy the database to a world readable/writeable directory. This allows the adb pull user access.

$ cp /data/data/your.package.name/databases/database_name /sdcard

Then, replace the existing read/write privileges. This is important for the security of your app, however the privileges will be replaced on the next install.

$ run-as your.package.name
$ chmod 660 databases/database_name 
$ chmod 660 databases
$ exit # Exit the shell started with run-as

Finally, copy the database to the local disk.

$ exit # Exits shell on the mobile device (from adb shell) 
$ adb pull /sdcard/database_name

In my case I was calling View::make('User/index'), where in fact my view was in user directory and it was called index.blade.php. Ergo after I changed it to View@make('user.index') all started working.

D:\JavaProjects\OlivePressApp\com\lynda\olivepress\Main.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\press\OlivePress.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\olives\Kalamata.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\olives\Ligurian.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\olives\Olive.class

Main.class is in package com.lynda.olivepress

There are two other packages:

com.lynda.olivepress.press

com.lynda.olivepress.olive

1) Create a file named "Manifest.txt" with Two Lines, First with Main-Class and a Second Empty Line.

Main-Class: com.lynda.olivepress.Main

D:\JavaProjects\OlivePressApp\ Manifest.txt

2) Create JAR with Manifest and Main-Class Entry Point

D:\JavaProjects\OlivePressApp>jar cfm OlivePressApp.jar Manifest.txt com/lynda/olivepress/Main.class com/lynda/olivepress/*

3) Run JAR

java -jar OlivePressApp.jar

Note: com/lynda/olivepress/* means including the other two packages mentioned above, before point 1)

You are splitting a string on a fairly complex sub string. I'd use regular expressions instead of String.Split. The later is more for tokenizing you text.

For example:

var rx = new System.Text.RegularExpressions.Regex("is Marco and");
var array = rx.Split("My name is Marco and I'm from Italy");

I struggled with all the answers here, starting with Pascal's solution, which is getting harder with the Java compiler not binding against rt.jar by default any more (and using internal classes makes it specific to that runtime implementation).

The answer from edubriguenti brought me close. The way the handler is hooked up in the final bit of code didn't work for me, though - it was never called.

I ended up using a variation of his handler class, but wired it into the javax.xml.ws.Service instance like this:

Service service = Service.create(url, qname); service.setHandlerResolver( portInfo -> Collections.singletonList(new SOAPHeaderHandler(handlerArgs)) );

Comparator.comparing

In Java 8, Collections have been enhanced by using lambda. So finding max and min can be accomplished as follows, using Comparator.comparing:

Code:

List<Integer> ints = Stream.of(12, 72, 54, 83, 51).collect(Collectors.toList());
System.out.println("the list: ");
ints.forEach((i) -> {
    System.out.print(i + " ");
});
System.out.println("");
Integer minNumber = ints.stream()
        .min(Comparator.comparing(i -> i)).get();
Integer maxNumber = ints.stream()
        .max(Comparator.comparing(i -> i)).get();

System.out.println("Min number is " + minNumber);
System.out.println("Max number is " + maxNumber);

Output:

 the list: 12 72 54 83 51  
 Min number is 12 
 Max number is 83

The simplest way I found

1. Go to your repo link for example:- https://github.com/someuser/someRepo.git

2. Click on setting tab.

the first thing you can see is your repo name, you can edit that.

Note:- If you have cloned repo on local so, change its folder name manually, that's all.

I put

<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>

first thing after

<head>

(I read it somewhere, I can't recall)

I could not believe it did work!!

Anacoda3-4.2.0 Uses python 3.5 You can find the same in the link given below : https://repo.continuum.io/archive/Anaconda3-4.2.0-Windows-x86_64.exe

I faced the same problem and found the correct version by checking the available Anaconda 4.2.0 distributions in installer archive here

To add to the above correct answer :- For my case in shell, this code worked (working on sqoop)

ROOT_PATH="path/to/the/folder"
--options-file  $ROOT_PATH/query.txt

Attention: this is an extremely rough and oversimplified sketch, assuming the simplest possible HTTP request (no HTTPS, no HTTP2, no extras), simplest possible DNS, no proxies, single-stack IPv4, one HTTP request only, a simple HTTP server on the other end, and no problems in any step. This is, for most contemporary intents and purposes, an unrealistic scenario; all of these are far more complex in actual use, and the tech stack has become an order of magnitude more complicated since this was written. With this in mind, the following timeline is still somewhat valid:

1. browser checks cache; if requested object is in cache and is fresh, skip to #9
2. browser asks OS for server's IP address
3. OS makes a DNS lookup and replies the IP address to the browser
4. browser opens a TCP connection to server (this step is much more complex with HTTPS)
5. browser sends the HTTP request through TCP connection
6. browser receives HTTP response and may close the TCP connection, or reuse it for another request
7. browser checks if the response is a redirect or a conditional response (3xx result status codes), authorization request (401), error (4xx and 5xx), etc.; these are handled differently from normal responses (2xx)
8. if cacheable, response is stored in cache
9. browser decodes response (e.g. if it's gzipped)
10. browser determines what to do with response (e.g. is it a HTML page, is it an image, is it a sound clip?)
11. browser renders response, or offers a download dialog for unrecognized types

Again, discussion of each of these points have filled countless pages; take this only as a summary, abridged for the sake of clarity. Also, there are many other things happening in parallel to this (processing typed-in address, speculative prefetching, adding page to browser history, displaying progress to user, notifying plugins and extensions, rendering the page while it's downloading, pipelining, connection tracking for keep-alive, cookie management, checking for malicious content etc.) - and the whole operation gets an order of magnitude more complex with HTTPS (certificates and ciphers and pinning, oh my!).

Today I was looking for this and Mr Brandon Rude gave an excellent answer. Unfortunately, AsyncTask is now depricated, you can still use it, but it gives you a warning which is very annoying. So an alternative is to use Executors like this way (in kotlin):

    val someRunnable = object : Runnable{
      override fun run() {
        // todo: do your background tasks
        requireActivity().runOnUiThread{
          // update views / ui if you are in a fragment
        };
        /*
        runOnUiThread {
          // update ui if you are in an activity
        }
        * */
      }
    };
    Executors.newSingleThreadExecutor().execute(someRunnable);

And in java it looks like this:

        Runnable someRunnable = new Runnable() {
            @Override
            public void run() {
                // todo: background tasks
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // todo: update your ui / view in activity
                    }
                });

                /*
                requireActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // todo: update your ui / view in Fragment
                    }
                });*/
            }
        };

        Executors.newSingleThreadExecutor().execute(someRunnable);

you need to include the Wordpress loop in your search.php this is example

search.php template file:

<?php get_header(); ?>
<?php
$s=get_search_query();
$args = array(
                's' =>$s
            );
    // The Query
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) {
        _e("<h2 style='font-weight:bold;color:#000'>Search Results for: ".get_query_var('s')."</h2>");
        while ( $the_query->have_posts() ) {
           $the_query->the_post();
                 ?>
                    <li>
                        <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
                    </li>
                 <?php
        }
    }else{
?>
        <h2 style='font-weight:bold;color:#000'>Nothing Found</h2>
        <div class="alert alert-info">
          <p>Sorry, but nothing matched your search criteria. Please try again with some different keywords.</p>
        </div>
<?php } ?>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

angular.module('elnApp')
.directive('jqdatepicker', function() {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function(scope, element, attrs, ctrl) {
            $(element).datepicker({
                dateFormat: 'dd.mm.yy',
                onSelect: function(date) {
                    ctrl.$setViewValue(date);
                    ctrl.$render();
                    scope.$apply();
                }
            });
        }
    };
});

No Worries! I have found the solution! I just installed https://msdn.microsoft.com/en-us/windows/desktop/bg162891.aspx and it all worked fine :)

That is not possible with a normal query since the in clause needs separate values and not a single value containing a comma separated list. One solution would be a dynamic query

declare @myList varchar(100)
set @myList = '(1,2,5,7,10)'
exec('select * from DBTable where id IN ' + @myList)

The simplest approach IMO is to use Guava and its ByteStreams class:

byte[] bytes = ByteStreams.toByteArray(in);

Or for a file:

byte[] bytes = Files.toByteArray(file);

Alternatively (if you didn't want to use Guava), you could create a ByteArrayOutputStream, and repeatedly read into a byte array and write into the ByteArrayOutputStream (letting that handle resizing), then call ByteArrayOutputStream.toByteArray().

Note that this approach works whether you can tell the length of your input or not - assuming you have enough memory, of course.

timeout = int(seconds)

Since requests >= 2.4.0, you can use the timeout argument, i.e:

requests.get('https://duckduckgo.com/', timeout=10)

Note:

timeout is not a time limit on the entire response download; rather, an exception is raised if the server has not issued a response for timeout seconds ( more precisely, if no bytes have been received on the underlying socket for timeout seconds). If no timeout is specified explicitly, requests do not time out.

If you are doing this because you want more context in your search, you can do this:

cat BIG_FILE.txt | less

Doing a search in less should highlight your search terms.

Or pipe the output to your favorite editor. One example:

cat BIG_FILE.txt | vim -

Then search/highlight/replace.

You can see the privileges here.

Then you can edit the user

It's very simple.

You can call it from anywhere in APP.

$out = new \Symfony\Component\Console\Output\ConsoleOutput();
$out->writeln("Hello from Terminal");

I think no one actually has answered to the first question:

Why did they create those variables?

Those variables aren't strictly necessary. It's true. You can perfectly do something like this:

MONTH_CHOICES = (
    ("JANUARY", "January"),
    ("FEBRUARY", "February"),
    ("MARCH", "March"),
    # ....
    ("DECEMBER", "December"),
)

month = models.CharField(max_length=9,
                  choices=MONTH_CHOICES,
                  default="JANUARY")

Why using variables is better? Error prevention and logic separation.

JAN = "JANUARY"
FEB = "FEBRUARY"
MAR = "MAR"
# (...)

MONTH_CHOICES = (
    (JAN, "January"),
    (FEB, "February"),
    (MAR, "March"),
    # ....
    (DEC, "December"),
)

Now, imagine you have a view where you create a new Model instance. Instead of doing this:

new_instance = MyModel(month='JANUARY')

You'll do this:

new_instance = MyModel(month=MyModel.JAN)

In the first option you are hardcoding the value. If there is a set of values you can input, you should limit those options when coding. Also, if you eventually need to change the code at the Model layer, now you don't need to make any change in the Views layer.

Kevlar is correct.

An alternative to a custom DLL is Lua Alien

Use Collections.synchronizedList().

Ex:

Collections.synchronizedList(new ArrayList<YourClassNameHere>())

The last parameter to the rgba() function is the "alpha" or "opacity" parameter. If you set it to 0 it will mean "completely transparent", and the first three parameters (the red, green, and blue channels) won't matter because you won't be able to see the color anyway.

With that in mind, I would choose rgba(0, 0, 0, 0) because:

1. it's less typing,
2. it keeps a few extra bytes out of your CSS file, and
3. you will see an obvious problem if the alpha value changes to something undesirable.

You could avoid the rgba model altogether and use the transparent keyword instead, which according to w3.org, is equivalent to "transparent black" and should compute to rgba(0, 0, 0, 0). For example:

h1 {
    background-color: transparent;
}

This saves you yet another couple bytes while your intentions of using transparency are obvious (in case one is unfamiliar with RGBA).

As of CSS3, you can use the transparent keyword for any CSS property that accepts a color.

To serve all requests from a Spring app as well as /favicon.ico and the JSP files from /WEB-INF/jsp/* that Spring's AbstractUrlBasedView will request you can just remap the jsp servlet and default servlet:

  <servlet>
    <servlet-name>springapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>jsp</servlet-name>
    <url-pattern>/WEB-INF/jsp/*</url-pattern>
  </servlet-mapping>

  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/favicon.ico</url-pattern>
  </servlet-mapping>

  <servlet-mapping>
    <servlet-name>springapp</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>

We can't rely on the *.jsp url-pattern on the standard mapping for the jsp servlet because the path pattern '/*' is matched before any extension mapping is checked. Mapping the jsp servlet to a deeper folder means it's matched first. Matching '/favicon.ico' exactly happens before path pattern matching. Deeper path matches will work, or exact matches, but no extension matches can make it past the '/*' path match. Mapping '/' to default servlet doesn't appear to work. You'd think the exact '/' would beat the '/*' path pattern on springapp.

The above filter solution doesn't work for forwarded/included JSP requests from the application. To make it work I had to apply the filter to springapp directly, at which point the url-pattern matching was useless as all requests that go to the application also go to its filters. So I added pattern matching to the filter and then learned about the 'jsp' servlet and saw that it doesn't remove the path prefix like the default servlet does. That solved my problem, which was not exactly the same but common enough.

If u want to set background of the list then place the image before the < Textview>

< ImageView
android:background="@drawable/image_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>

and if u want to change color then put color code on above textbox like this

 android:textColor="#ffffff"

Question 1: How do create a DataTable in C#?

Answer 1:

DataTable dt = new DataTable(); // DataTable created

// Add columns in your DataTable
dt.Columns.Add("Name");
dt.Columns.Add("Marks");

Note: There is no need to Clear() the DataTable after creating it.

Question 2: How to add row(s)?

Answer 2: Add one row:

dt.Rows.Add("Ravi","500");

Add multiple rows: use ForEach loop

DataTable dt2 = (DataTable)Session["CartData"]; // This DataTable contains multiple records
foreach (DataRow dr in dt2.Rows)
{
    dt.Rows.Add(dr["Name"], dr["Marks"]);
}
