4 years later, ES6 way simpler version.

function getCookie(name) {
  let cookie = {};
  document.cookie.split(';').forEach(function(el) {
    let [k,v] = el.split('=');
    cookie[k.trim()] = v;
  })
  return cookie[name];
}

I have also created a gist to use it as a Cookie object. e.g., Cookie.set(name,value) and Cookie.get(name)

This read all cookies instead of scanning through. It's ok for small number of cookies.

var text = html.replace(/<\/?("[^"]*"|'[^']*'|[^>])*(>|$)/g, "");

This is a regex version, which is more resilient to malformed HTML, like:

Unclosed tags

Some text <img

"<", ">" inside tag attributes

Some text <img alt="x > y">

Newlines

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

The code

var html = '<br>This <img alt="a>b" \r\n src="a_b.gif" />is > \nmy<>< > <a>"text"</a'
var text = html.replace(/<\/?("[^"]*"|'[^']*'|[^>])*(>|$)/g, "");

That functionality is still suspiciously missing from the Java reflection API as far as I know. You can get a package object by just doing this:

Package packageObj = Package.getPackage("my.package");

But as you probably noticed, that won't let you list the classes in that package. As of right now, you have to take sort of a more filesystem-oriented approach.

I found some sample implementations in this post

I'm not 100% sure these methods will work when your classes are buried in JAR files, but I hope one of those does it for you.

I agree with @skaffman...if you have another way of going about this, I'd recommend doing that instead.

import nltk is Python syntax, and as such won't work in a shell script.

To test the version of nltk and scikit_learn, you can write a Python script and run it. Such a script may look like

import nltk
import sklearn

print('The nltk version is {}.'.format(nltk.__version__))
print('The scikit-learn version is {}.'.format(sklearn.__version__))

# The nltk version is 3.0.0.
# The scikit-learn version is 0.15.2.

Note that not all Python packages are guaranteed to have a __version__ attribute, so for some others it may fail, but for nltk and scikit-learn at least it will work.

If you only care about the conflict resolution and not about keeping the commit history, the following method should work. Say you want to merge a.py b.py from BRANCHA into BRANCHB. First, make sure any changes in BRANCHB are either committed or stashed away, and that there are no untracked files. Then:

git checkout BRANCHB
git merge BRANCHA
# 'Accept' all changes
git add .
# Clear staging area
git reset HEAD -- .
# Stash only the files you want to keep
git stash push a.py b.py
# Remove all other changes
git add .
git reset --hard
# Now, pull the changes
git stash pop

git won't recognize that there are conflicts in a.py b.py, but the merge conflict markers are there if there were in fact conflicts. Using a third-party merge tool, such as VSCode, one will be able to resolve conflicts more comfortably.

I have used a trick to handle the apostrophe special character. When replacing ' for \' you need to place four backslashes before the apostrophe.

str.replaceAll("'","\\\\'");

M-x customize-face RET default will allow you to set the face default face, on which all other faces base on. There you can set the font-size.

Here is what is in my .emacs. actually, color-theme will set the basics, then my custom face setting will override some stuff. the custom-set-faces is written by emacs's customize-face mechanism:

;; my colour theme is whateveryouwant :)
(require 'color-theme)
(color-theme-initialize)
(color-theme-whateveryouwant)

(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.

You can add functionality to an Array by extending its prototype object.

Array.prototype.nullify = function( n ) {
    n = n >>> 0;
    for( var i = 0; i < n; ++i ) {
        this[ i ] = null;
    }
    return this;
};

Then:

var arr = [].nullify(9);

or:

var arr = [].nullify(9).map(function() { return [].nullify(9); });

Update December 2012 (19 months later):

The blog post "Jin Mingjian: Eclipse Darker Theme" mentions this GitHub repo "eclipse themes - darker":

The big fun is that, the codes are minimized by using Eclipse4 platform technologies like dependency injection.
It proves that again, the concise codes and advanced features could be achieved by contributing or extending with the external form (like library, framework).
New language is not necessary just for this kind of purpose.

Update July 2012 (14 months later):

With the latest Eclipse4.2 (June 2012, "Juno") release, you can implement what I originally described below: a CSS-based fully dark theme for Eclipse.
See the article by Lars Vogel in "Eclipse 4 is beautiful – Create your own Eclipse 4 theme":

If you want to play with it, you only need to write a plug-in, create a CSS file and use the org.eclipse.e4.ui.css.swt.theme extension point to point to your file.
If you export your plug-in, place it in the “dropins” folder of your Eclipse installation and your styling is available.

Original answer: August 2011

With Eclipse 3.x, theme is only for the editors, as you can see in the site "Eclipse Color Themes".
Anything around that is managed by windows system colors.
That is what you need to change to have any influence on Eclipse global colors around editors.

Eclipse 4 will provide much advance theme options: See "Eclipse 4.0 – So you can theme me Part 1" and "Eclipse 4.0 RCP: Dynamic CSS Theme Switching".

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

In the first case you are simply starting a new thread while in the second case you are entering in the thread pool.

The thread pool job is to share and recycle threads. It allows to avoid losing a few millisecond every time we need to create a new thread.

There are a several ways to enter the thread pool:

• with the TPL (Task Parallel Library) like you did
• by calling ThreadPool.QueueUserWorkItem
• by calling BeginInvoke on a delegate
• when you use a BackgroundWorker

Here I found this article which is send post request using JsonConvert.SerializeObject() & StringContent() to HttpClient.PostAsync data

static async Task Main(string[] args)
{
    var person = new Person();
    person.Name = "John Doe";
    person.Occupation = "gardener";

    var json = Newtonsoft.Json.JsonConvert.SerializeObject(person);
    var data = new System.Net.Http.StringContent(json, Encoding.UTF8, "application/json");

    var url = "https://httpbin.org/post";
    using var client = new HttpClient();

    var response = await client.PostAsync(url, data);

    string result = response.Content.ReadAsStringAsync().Result;
    Console.WriteLine(result);
}

From official doc :

fromHtml(String) method was deprecated in API level 24. use fromHtml(String, int) instead.

1. TO_HTML_PARAGRAPH_LINES_CONSECUTIVE Option for toHtml(Spanned, int): Wrap consecutive lines of text delimited by '\n' inside <p> elements.

2. TO_HTML_PARAGRAPH_LINES_INDIVIDUAL Option for toHtml(Spanned, int): Wrap each line of text delimited by '\n' inside a <p> or a <li> element.

litersOfPetrol = Float.parseFloat(df.format(litersOfPetrol));

System.out.println("liters of petrol before putting in editor : "+litersOfPetrol);

You print Float here, that has no format at all.

To print formatted float, just use

String formatted = df.format(litersOfPetrol);
System.out.println("liters of petrol before putting in editor : " + formatted);

To expand on Berry's answer, that setting the access level to protected allows __get and __set to be used with explicitly declared properties (when accessed outside the class, at least) and the speed being considerably slower, I'll quote a comment from another question on this topic and make a case for using it anyway:

I agree that __get is more slow to a custom get function (doing the same things), this is 0.0124455 the time for __get() and this 0.0024445 is for custom get() after 10000 loops. – Melsi Nov 23 '12 at 22:32 Best practice: PHP Magic Methods __set and __get

According to Melsi's tests, considerably slower is about 5 times slower. That is definitely considerably slower, but also note that the tests show that you can still access a property with this method 10,000 times, counting time for loop iteration, in roughly 1/100 of a second. It is considerably slower in comparison with actual get and set methods defined, and that is an understatement, but in the grand scheme of things, even 5 times slower is never actually slow.

The computing time of the operation is still negligible and not worth considering in 99% of real world applications. The only time it should really be avoided is when you're actually going to be accessing the properties over 10,000 times in a single request. High traffic sites are doing something really wrong if they can't afford throwing a few more servers up to keep their applications running. A single line text ad on the footer of a high traffic site where the access rate becomes an issue could probably pay for a farm of 1,000 servers with that line of text. The end user is never going to be tapping their fingers wondering what is taking the page so long to load because your application's property access takes a millionth of a second.

I say this speaking as a developer coming from a background in .NET, but invisible get and set methods to the consumer is not .NET's invention. They simply aren't properties without them, and these magic methods are PHP's developer's saving grace for even calling their version of properties "properties" at all. Also, the Visual Studio extension for PHP does support intellisense with protected properties, with that trick in mind, I'd think. I would think with enough developers using the magic __get and __set methods in this way, the PHP developers would tune up the execution time to cater to the developer community.

Edit: In theory, protected properties seemed like it'd work in most situation. In practice, it turns out that there's a lot of times you're going to want to use your getters and setters when accessing properties within the class definition and extended classes. A better solution is a base class and interface for when extending other classes, so you can just copy the few lines of code from the base class into the implementing class. I'm doing a bit more with my project's base class, so I don't have an interface to provide right now, but here is the untested stripped down class definition with magic property getting and setting using reflection to remove and move the properties to a protected array:

/** Base class with magic property __get() and __set() support for defined properties. */
class Component {
    /** Gets the properties of the class stored after removing the original
     * definitions to trigger magic __get() and __set() methods when accessed. */
    protected $properties = array();

    /** Provides property get support. Add a case for the property name to
     * expand (no break;) or replace (break;) the default get method. When
     * overriding, call parent::__get($name) first and return if not null,
     * then be sure to check that the property is in the overriding class
     * before doing anything, and to implement the default get routine. */
    public function __get($name) {
        $caller = array_shift(debug_backtrace());
        $max_access = ReflectionProperty::IS_PUBLIC;
        if (is_subclass_of($caller['class'], get_class($this)))
            $max_access = ReflectionProperty::IS_PROTECTED;
        if ($caller['class'] == get_class($this))
            $max_access = ReflectionProperty::IS_PRIVATE;
        if (!empty($this->properties[$name])
            && $this->properties[$name]->class == get_class()
            && $this->properties[$name]->access <= $max_access)
            switch ($name) {
                default:
                    return $this->properties[$name]->value;
            }
    }

    public function __set($name, $value) {
        $caller = array_shift(debug_backtrace());
        $max_access = ReflectionProperty::IS_PUBLIC;
        if (is_subclass_of($caller['class'], get_class($this)))
            $max_access = ReflectionProperty::IS_PROTECTED;

            && $this->properties[$name]->access <= $max_access)
            switch ($name) {
                default:
                    $this->properties[$name]->value = $value;
            }
    }

    /** Constructor for the Component. Call first when overriding. */
    function __construct() {
        // Removing and moving properties to $properties property for magic
        // __get() and __set() support.
        $reflected_class = new ReflectionClass($this);
        $properties = array();
        foreach ($reflected_class->getProperties() as $property) {
            if ($property->isStatic()) { continue; }
            $properties[$property->name] = (object)array(
                'name' => $property->name, 'value' => $property->value
                , 'access' => $property->getModifier(), 'class' => get_class($this));
            unset($this->{$property->name}); }
        $this->properties = $properties;
    }
}

My apologies if there are any bugs in the code.

Change your code as given below:

@Override
protected void onPostExecute(String result) {

    runOnUiThread(new Runnable() {
        public void run() {
            TextView txt = (TextView) findViewById(R.id.output);
            txt.setText("Executed");
        }
    });
}

cvc-elt.1: Cannot find the declaration of element 'Root'. [7]

Your schemaLocation attribute on the root element should be xsi:schemaLocation, and you need to fix it to use the right namespace.

You should probably change the targetNamespace of the schema and the xmlns of the document to http://myNameSpace.com (since namespaces are supposed to be valid URIs, which Test.Namespace isn't, though urn:Test.Namespace would be ok). Once you do that it should find the schema. The point is that all three of the schema's target namespace, the document's namespace, and the namespace for which you're giving the schema location must be the same.

(though it still won't validate as your <element2> contains an <element3> in the document where the schema expects item)

For the simplest choice, I'd go with minidom: http://docs.python.org/library/xml.dom.minidom.html . It is built in to the python standard library and is straightforward to use in simple cases.

Here's a pretty easy to follow tutorial: http://www.boddie.org.uk/python/XML_intro.html

You can use the function last_insert_rowid():

The last_insert_rowid() function returns the ROWID of the last row insert from the database connection which invoked the function. The last_insert_rowid() SQL function is a wrapper around the sqlite3_last_insert_rowid() C/C++ interface function.

Sounds to me like at least one of those tables has defined UserID as a uniqueidentifier, not an int. Did you check the data in each table? What does SELECT TOP 1 UserID FROM each table yield? An int or a GUID?

EDIT

I think you have built a procedure based on all tables that contain a column named UserID. I think you should not have included the aspnet_Membership table in your script, since it's not really one of "your" tables.

If you meant to design your tables around the aspnet_Membership database, then why are the rest of the columns int when that table clearly uses a uniqueidentifier for the UserID column?

in my case, i have a cdn,and i am going to place all my processed static files (js,imgs,fonts...) into my cdn,suppose the url is http://my.cdn.com/

so if there is a js file which is the orginal refer url in html is './js/my.js' it should became http://my.cdn.com/js/my.js in production environment

in that case,what i need to do is just set publicpath equals http://my.cdn.com/ and webpack will automatic add that prefix

File size is important. There is a limit of ~120MB for a single file. In my case, .gitignore using Visual Studio had the file listed, but the file was still committed. When using the git cli, we can get more detail information about the error.

pre-receive hook declined was as a result of the big file. Basically validating the push.

To resolve it, I removed the last commit using:

git reset --soft HEAD~1

I then excluded the file from the commit.

Note: Use HEAD~N to go back to N number of previous commits. (i.e. 3, 4) Always use the --soft switch to maintain changes in the folder

hope it helps.

In batch file:

1 @echo off(solo)=>output nothing

2 echo off(solo)=> the “echo off” shows in the command line

3 echo off(then echo something) =>

4 @echo off(then echo something)=>

See, echo off(solo), means no output in the command line, but itself shows; @echo off(solo), means no output in the command line, neither itself;

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

you can simply write the following command in the terminal of your linux system and get the java path :- echo $JAVA_HOME

If you are using requests module, an alternative option is to write an auth class, as discussed in "New Forms of Authentication":

import requests

class BearerAuth(requests.auth.AuthBase):
    def __init__(self, token):
        self.token = token
    def __call__(self, r):
        r.headers["authorization"] = "Bearer " + self.token
        return r

and then can you send requests like this

response = requests.get('https://www.example.com/', auth=BearerAuth('3pVzwec1Gs1m'))

which allows you to use the same auth argument just like basic auth, and may help you in certain situations.

From Google

Request.RawUrl.Split(new[] {'?'})[0];

Initialize empty frame with column names

import pandas as pd

col_names =  ['A', 'B', 'C']
my_df  = pd.DataFrame(columns = col_names)
my_df

Add a new record to a frame

my_df.loc[len(my_df)] = [2, 4, 5]

You also might want to pass a dictionary:

my_dic = {'A':2, 'B':4, 'C':5}
my_df.loc[len(my_df)] = my_dic 

Append another frame to your existing frame

col_names =  ['A', 'B', 'C']
my_df2  = pd.DataFrame(columns = col_names)
my_df = my_df.append(my_df2)

Performance considerations

If you are adding rows inside a loop consider performance issues. For around the first 1000 records "my_df.loc" performance is better, but it gradually becomes slower by increasing the number of records in the loop.

If you plan to do thins inside a big loop (say 10M? records or so), you are better off using a mixture of these two; fill a dataframe with iloc until the size gets around 1000, then append it to the original dataframe, and empty the temp dataframe. This would boost your performance by around 10 times.

you can do

DELETE FROM `mytable` WHERE `id` > 0

This is for Larave 5.2.x and greater. If you want to have an option to serve some content over HTTPS and others over HTTP here is a solution that worked for me. You may wonder, why would someone want to serve only some content over HTTPS? Why not serve everything over HTTPS?

Although, it's totally fine to serve the whole site over HTTPS, severing everything over HTTPS has an additional overhead on your server. Remember encryption doesn't come cheap. The slight overhead also has an impact on your app response time. You could argue that commodity hardware is cheap and the impact is negligible but I digress :) I don't like the idea of serving marketing content big pages with images etc over https. So here it goes. It's similar to what others have suggest above using middleware but it's a full solution that allows you to toggle back and forth between HTTP/HTTPS.

First create a middleware.

php artisan make:middleware ForceSSL

This is what your middleware should look like.

<?php

namespace App\Http\Middleware;

use Closure;

class ForceSSL
{

    public function handle($request, Closure $next)
    {

        if (!$request->secure()) {
            return redirect()->secure($request->getRequestUri());
        }

        return $next($request);
    }
}

Note that I'm not filtering based on environment because I have HTTPS setup for both local dev and production so there is not need to.

Add the following to your routeMiddleware \App\Http\Kernel.php so that you can pick and choose which route group should force SSL.

    protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'can' => \Illuminate\Foundation\Http\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    'forceSSL' => \App\Http\Middleware\ForceSSL::class,
];

Next, I'd like to secure two basic groups login/signup etc and everything else behind Auth middleware.

Route::group(array('middleware' => 'forceSSL'), function() {
/*user auth*/
Route::get('login', 'AuthController@showLogin');
Route::post('login', 'AuthController@doLogin');

// Password reset routes...
Route::get('password/reset/{token}', 'Auth\PasswordController@getReset');
Route::post('password/reset', 'Auth\PasswordController@postReset');

//other routes like signup etc

});


Route::group(['middleware' => ['auth','forceSSL']], function()
 {
Route::get('dashboard', function(){
    return view('app.dashboard');
});
Route::get('logout', 'AuthController@doLogout');

//other routes for your application
});

Confirm that your middlewares are applied to your routes properly from console.

php artisan route:list

Now you have secured all the forms or sensitive areas of your application, the key now is to use your view template to define your secure and public (non https) links.

Based on the example above you would render your secure links as follows -

<a href="{{secure_url('/login')}}">Login</a>
<a href="{{secure_url('/signup')}}">SignUp</a>

Non secure links can be rendered as

<a href="{{url('/aboutus',[],false)}}">About US</a></li>
<a href="{{url('/promotion',[],false)}}">Get the deal now!</a></li>

What this does is renders a fully qualified URL such as https://yourhost/login and http://yourhost/aboutus

If you were not render fully qualified URL with http and use a relative link url('/aboutus') then https would persists after a user visits a secure site.

Hope this helps!

Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.

You can check this by running in Windows PowerShell:

> Get-Service ssh-agent

And then check the output of status is not running.

Status   Name               DisplayName
------   ----               -----------
Stopped  ssh-agent          OpenSSH Authentication Agent

Then check that the service has been disabled by running

> Get-Service ssh-agent | Select StartType

StartType
---------
Disabled

I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:

 > Get-Service -Name ssh-agent | Set-Service -StartupType Manual

Alternatively, you can set it through the GUI if you prefer.

As the instructions state, using the open() function does work, and opens the default web browser - usually I would say: "why wouldn't I want to use Firefox?!" (my default and favorite browser)

import webbrowser as wb
wb.open_new_tab('http://www.google.com')

The above should work for the computer's default browser. However, what if you want to to open in Google Chrome?

The proper way to do this is:

import webbrowser as wb
wb.get('chrome %s').open_new_tab('http://www.google.com')

To be honest, I'm not really sure that I know the difference between 'chrome' and 'google-chrome', but apparently there is some since they've made the two different type names in the webbrowser documentation.

However, doing this didn't work right off the bat for me. Every time, I would get the error:

Traceback (most recent call last):
File "C:\Python34\programs\a_temp_testing.py", line 3, in <module>
wb.get('google-chrome')
File "C:\Python34\lib\webbrowser.py", line 51, in get
raise Error("could not locate runnable browser")
webbrowser.Error: could not locate runnable browser

To solve this, I had to add the folder for chrome.exe to System PATH. My chrome.exe executable file is found at:

C:\Program Files (x86)\Google\Chrome\Application

You should check whether it is here or not for yourself.

To add this to your Environment Variables System PATH, right click on your Windows icon and go to System. System Control Panel applet (Start - Settings - Control Panel - System). Change advanced settings, or the advanced tab, and select the button there called Environment Varaibles.

Once you click on Environment Variables here, another window will pop up. Scroll through the items, select PATH, and click edit.

Once you're in here, click New to add the folder path to your chrome.exe file. Like I said above, mine was found at:

C:\Program Files (x86)\Google\Chrome\Application

Click save and exit out of there. Then make sure you reboot your computer.

Hope this helps!

I think (I'm not certain) that foreign key constraints won't do precisely what you want given your table design. Perhaps the best thing to do is to define a stored procedure that will delete a category the way you want, and then call that procedure whenever you want to delete a category.

CREATE PROCEDURE `DeleteCategory` (IN category_ID INT)
LANGUAGE SQL
NOT DETERMINISTIC
MODIFIES SQL DATA
SQL SECURITY DEFINER
BEGIN

DELETE FROM
    `products`
WHERE
    `id` IN (
        SELECT `products_id`
        FROM `categories_products`
        WHERE `categories_id` = category_ID
    )
;

DELETE FROM `categories`
WHERE `id` = category_ID;

END

You also need to add the following foreign key constraints to the linking table:

ALTER TABLE `categories_products` ADD
    CONSTRAINT `Constr_categoriesproducts_categories_fk`
    FOREIGN KEY `categories_fk` (`categories_id`) REFERENCES `categories` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE,
    CONSTRAINT `Constr_categoriesproducts_products_fk`
    FOREIGN KEY `products_fk` (`products_id`) REFERENCES `products` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE

The CONSTRAINT clause can, of course, also appear in the CREATE TABLE statement.

Having created these schema objects, you can delete a category and get the behaviour you want by issuing CALL DeleteCategory(category_ID) (where category_ID is the category to be deleted), and it will behave how you want. But don't issue a normal DELETE FROM query, unless you want more standard behaviour (i.e. delete from the linking table only, and leave the products table alone).

MySQL 5.7 Now supports a native JSON data type similar to MongoDB and other schemaless document data stores:

JSON support

Beginning with MySQL 5.7.8, MySQL supports a native JSON type. JSON values are not stored as strings, instead using an internal binary format that permits quick read access to document elements. JSON documents stored in JSON columns are automatically validated whenever they are inserted or updated, with an invalid document producing an error. JSON documents are normalized on creation, and can be compared using most comparison operators such as =, <, <=, >, >=, <>, !=, and <=>; for information about supported operators as well as precedence and other rules that MySQL follows when comparing JSON values, see Comparison and Ordering of JSON Values.

MySQL 5.7.8 also introduces a number of functions for working with JSON values. These functions include those listed here:

1. Functions that create JSON values: JSON_ARRAY(), JSON_MERGE(), and JSON_OBJECT(). See Section 12.16.2, “Functions That Create JSON Values”.
2. Functions that search JSON values: JSON_CONTAINS(), JSON_CONTAINS_PATH(), JSON_EXTRACT(), JSON_KEYS(), and JSON_SEARCH(). See Section 12.16.3, “Functions That Search JSON Values”.
3. Functions that modify JSON values: JSON_APPEND(), JSON_ARRAY_APPEND(), JSON_ARRAY_INSERT(), JSON_INSERT(), JSON_QUOTE(), JSON_REMOVE(), JSON_REPLACE(), JSON_SET(), and JSON_UNQUOTE(). See Section 12.16.4, “Functions That Modify JSON Values”.
4. Functions that provide information about JSON values: JSON_DEPTH(), JSON_LENGTH(), JSON_TYPE(), and JSON_VALID(). See Section 12.16.5, “Functions That Return JSON Value Attributes”.

In MySQL 5.7.9 and later, you can use column->path as shorthand for JSON_EXTRACT(column, path). This works as an alias for a column wherever a column identifier can occur in an SQL statement, including WHERE, ORDER BY, and GROUP BY clauses. This includes SELECT, UPDATE, DELETE, CREATE TABLE, and other SQL statements. The left hand side must be a JSON column identifier (and not an alias). The right hand side is a quoted JSON path expression which is evaluated against the JSON document returned as the column value.

See Section 12.16.3, “Functions That Search JSON Values”, for more information about -> and JSON_EXTRACT(). For information about JSON path support in MySQL 5.7, see Searching and Modifying JSON Values. See also Secondary Indexes and Virtual Generated Columns.

Bitmasks are used when you want to encode multiple layers of information in a single number.

So (assuming unix file permissions) if you want to store 3 levels of access restriction (read, write, execute) you could check for each level by checking the corresponding bit.

rwx
---
110

110 in base 2 translates to 6 in base 10.

So you can easily check if someone is allowed to e.g. read the file by and'ing the permission field with the wanted permission.

Pseudocode:

PERM_READ = 4
PERM_WRITE = 2
PERM_EXEC = 1

user_permissions = 6

if (user_permissions & PERM_READ == TRUE) then
  // this will be reached, as 6 & 4 is true
fi

You need a working understanding of binary representation of numbers and logical operators to understand bit fields.

In general suppressing warnings is not the best solution as you may want to be warned when some unexpected input will be provided.
Solution below is wrapper for maintaining just NA during data type conversion. Doesn't require any package.

as.num = function(x, na.strings = "NA") {
    stopifnot(is.character(x))
    na = x %in% na.strings
    x[na] = 0
    x = as.numeric(x)
    x[na] = NA_real_
    x
}
as.num(c("1", "2", "X"), na.strings="X")
#[1]  1  2 NA

you can specify fields like this:

LOAD XML LOCAL INFILE '/pathtofile/file.xml' 
INTO TABLE my_tablename(personal_number, firstname, ...); 

my.1 <- table(myvec)

my.1[my.1 != 0] <- 1

rowSums(my.1)

This following program can handle large numbers ( number of digits greater than 20 )

package com.isEven.java;
import java.util.Scanner;

public class isEvenValuate{

public static void main(String[] args) {            

        Scanner in = new Scanner(System.in);
        String digit = in.next();

        int y = Character.getNumericValue(digit.charAt(digit.length()-1));

        boolean isEven = (y&1)==0;

        if(isEven)
            System.out.println("Even");
        else
            System.out.println("Odd");

    }
}

Here is the output ::

  122873215981652362153862153872138721637272

If you are using an SMTP server on the same box and your SMTP is bound to an IP address instead of "Any Assigned" it may fail because it is trying to use an IP address (like 127.0.0.1) that SMTP is not currently working on.

Okay, I think I know what you're looking for. It appears that GGT is a pretty good solution, as Reed Copsey suggested.

Personally, we rolled our own little library, because we deal with rational points a lot - lots of rational NURBS and Beziers.

It turns out that most 3D graphics libraries do computations with projective points that have no basis in projective math, because that's what gets you the answer you want. We ended up using Grassmann points, which have a solid theoretical underpinning and decreased the number of point types. Grassmann points are basically the same computations people are using now, with the benefit of a robust theory. Most importantly, it makes things clearer in our minds, so we have fewer bugs. Ron Goldman wrote a paper on Grassmann points in computer graphics called "On the Algebraic and Geometric Foundations of Computer Graphics".

Dot notation will break the type checking, switch to bracket notation. You might also try using the get() method. It also keeps AOT compilation in tact I've read.

this.form.get('controlName').value // safer
this.form.controlName.value // triggers type checking and breaks AOT

The time complexity, in Big O notation, for each function:

int recursiveFun1(int n)
{
    if (n <= 0)
        return 1;
    else
        return 1 + recursiveFun1(n-1);
}

This function is being called recursively n times before reaching the base case so its O(n), often called linear.

int recursiveFun2(int n)
{
    if (n <= 0)
        return 1;
    else
        return 1 + recursiveFun2(n-5);
}

This function is called n-5 for each time, so we deduct five from n before calling the function, but n-5 is also O(n). (Actually called order of n/5 times. And, O(n/5) = O(n) ).

int recursiveFun3(int n)
{
    if (n <= 0)
        return 1;
    else
        return 1 + recursiveFun3(n/5);
}

This function is log(n) base 5, for every time we divide by 5 before calling the function so its O(log(n))(base 5), often called logarithmic and most often Big O notation and complexity analysis uses base 2.

void recursiveFun4(int n, int m, int o)
{
    if (n <= 0)
    {
        printf("%d, %d\n",m, o);
    }
    else
    {
        recursiveFun4(n-1, m+1, o);
        recursiveFun4(n-1, m, o+1);
    }
}

Here, it's O(2^n), or exponential, since each function call calls itself twice unless it has been recursed n times.

int recursiveFun5(int n)
{
    for (i = 0; i < n; i += 2) {
        // do something
    }

    if (n <= 0)
        return 1;
    else
        return 1 + recursiveFun5(n-5);
}

And here the for loop takes n/2 since we're increasing by 2, and the recursion takes n/5 and since the for loop is called recursively, therefore, the time complexity is in

(n/5) * (n/2) = n^2/10,

due to Asymptotic behavior and worst-case scenario considerations or the upper bound that big O is striving for, we are only interested in the largest term so O(n^2).

Good luck on your midterms ;)

I have met the same issue today. After trying various method, I realize that just put the code of sizing inside $(window).load(function() {}) instead of document.ready would solve part of issue (if you are not ajaxing the page).

Perl 6 version

rx{
  ^

  $<month> = (\d ** 1..2)
  { $<month> <= 12 or fail }

  '/'

  $<day> = (\d ** 1..2)
  {
    given( +$<month> ){
      when 1|3|5|7|8|10|12 {
        $<day> <= 31 or fail
      }
      when 4|6|9|11 {
        $<day> <= 30 or fail
      }
      when 2 {
        $<day> <= 29 or fail
      }
      default { fail }
    }
  }

  '/'

  $<year> = (\d ** 4)

  $
}

After you use this to check the input the values are available in $/ or individually as $<month>, $<day>, $<year>. ( those are just syntax for accessing values in $/ )

No attempt has been made to check the year, or that it doesn't match the 29th of Feburary on non leap years.

Just to add my TSQL-scripted solution:

First of all; add a new database named backup_lookup. Then just run this script, inserting your own databases' root path and backup filepath

WITH REPLACE,
 MOVE 'Old Database Name' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\backup_lookup.mdf',
 MOVE 'Old Database Name_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\backup_lookup_log.ldf'

There's an example of how to use Font Awesome alongside an unordered list on their examples page.

<ul class="icons">
  <li><i class="icon-ok"></i> Lists</li>
  <li><i class="icon-ok"></i> Buttons</li>
  <li><i class="icon-ok"></i> Button groups</li>
  <li><i class="icon-ok"></i> Navigation</li>
  <li><i class="icon-ok"></i> Prepended form inputs</li>
</ul>

If you can't find it working after trying this code then you're not including the library correctly. According to their website, you should include the libraries as such:

<link rel="stylesheet" href="../css/bootstrap.css">
<link rel="stylesheet" href="../css/font-awesome.css">

Also check out the whimsical Chris Coyier's post on icon fonts on his website CSS Tricks.

Here's a screencast by him as well talking about how to create your own icon font-face.

Typescript recognizes the Date interface out of the box - just like you would with a number, string, or custom type. So Just use:

myDate : Date;

Accepting as valid the response of Prajeet Shrestha in this thread, I would like to extend his solution using the Label if it is known and the traits of the font.

Swift 4

extension NSMutableAttributedString {

    @discardableResult func normal(_ text: String) -> NSMutableAttributedString {
        let normal = NSAttributedString(string: text)
        append(normal)

        return self
    }

    @discardableResult func bold(_ text: String, withLabel label: UILabel) -> NSMutableAttributedString {

        //generate the bold font
        var font: UIFont = UIFont(name: label.font.fontName , size: label.font.pointSize)!
        font = UIFont(descriptor: font.fontDescriptor.withSymbolicTraits(.traitBold) ?? font.fontDescriptor, size: font.pointSize)

        //generate attributes
        let attrs: [NSAttributedStringKey: Any] = [NSAttributedStringKey.font: font]
        let boldString = NSMutableAttributedString(string:text, attributes: attrs)

        //append the attributed text
        append(boldString)

        return self
    }
}

Attribute Routing in MVC 5

Before MVC 5 you could map URLs to specific actions and controllers by calling routes.MapRoute(...) in the RouteConfig.cs file. This is where the url for the homepage is stored (Home/Index). However if you modify the default route as shown below,

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

keep in mind that this will affect the URLs of other actions and controllers. For example, if you had a controller class named ExampleController and an action method inside of it called DoSomething, then the expected default url ExampleController/DoSomething will no longer work because the default route was changed.

A workaround for this is to not mess with the default route and create new routes in the RouteConfig.cs file for other actions and controllers like so,

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
    name: "Example",
    url: "hey/now",
    defaults: new { controller = "Example", action = "DoSomething", id = UrlParameter.Optional }
);

Now the DoSomething action of the ExampleController class will be mapped to the url hey/now. But this can get tedious to do for every time you want to define routes for different actions. So in MVC 5 you can now add attributes to match urls to actions like so,

public class HomeController : Controller
{
    // url is now 'index/' instead of 'home/index'
    [Route("index")]
    public ActionResult Index()
    {
        return View();
    }
    // url is now 'create/new' instead of 'home/create'
    [Route("create/new")]
    public ActionResult Create()
    {
        return View();
    }
}

You can also use:

    sed -n 's/.*\/\([^\/]\{1,\}\)$/\1/p'

or

    sed -n 's/.*\/\([^\/]*\)$/\1/p'

This code retrieves first 100 rows from table in SQLSERVER 2012 and saves a picture per row as a file on local disk

 public void SavePicture()
    {
        SqlConnection con = new SqlConnection("Data Source=localhost;Integrated security=true;database=databasename");
        SqlDataAdapter da = new SqlDataAdapter("select top 100 [Name] ,[Picture] From tablename", con);
        SqlCommandBuilder MyCB = new SqlCommandBuilder(da);
        DataSet ds = new DataSet("tablename");
        byte[] MyData = new byte[0];
        da.Fill(ds, "tablename");
        DataTable table = ds.Tables["tablename"];
           for (int i = 0; i < table.Rows.Count;i++ )               
               {
                DataRow myRow;
                myRow = ds.Tables["tablename"].Rows[i];
                MyData = (byte[])myRow["Picture"];
                int ArraySize = new int();
                ArraySize = MyData.GetUpperBound(0);
                FileStream fs = new FileStream(@"C:\NewFolder\" + myRow["Name"].ToString() + ".jpg", FileMode.OpenOrCreate, FileAccess.Write);
                fs.Write(MyData, 0, ArraySize);
                fs.Close();
               }

    }

please note: Directory with NewFolder name should exist in C:\

This way worked very well in my situation. I just added some modifications based on other code presented in this thread.

import sys, os

   def write(self, data):
       self.stream.write(data)
       self.stream.flush()
       te.write(data)    # Write the data of stdout here to a text file as well

sys.stdout=Unbuffered(sys.stdout)

To update database type following codes in PowerShell...

Update-Database -context EnrollmentAppContext

*if more than one databases exist only use this codes,otherwise not necessary..

I had this issue myself, and I wanted to both be able to set the width, and have it update on rotate and allow the user to scale and zoom the page (the current answer provides the first but prevents the later as a side-effect).. so I came up with a fix that keeps the view width correct for the orientation, but still allows for zooming, though it is not super straight forward.

First, add the following Javascript to the webpage you are displaying:

 <script type='text/javascript'>
 function setViewPortWidth(width) {
  var metatags = document.getElementsByTagName('meta');
  for(cnt = 0; cnt < metatags.length; cnt++) { 
   var element = metatags[cnt];
   if(element.getAttribute('name') == 'viewport') {

    element.setAttribute('content','width = '+width+'; maximum-scale = 5; user-scalable = yes');
    document.body.style['max-width'] = width+'px';
   }
  }
 }
 </script>

Then in your - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation method, add:

float availableWidth = [EmailVC webViewWidth];
NSString *stringJS;

stringJS = [NSString stringWithFormat:@"document.body.offsetWidth"];
float documentWidth = [[_webView stringByEvaluatingJavaScriptFromString:stringJS] floatValue];

if(documentWidth > availableWidth) return; // Don't perform if the document width is larger then available (allow auto-scale)

// Function setViewPortWidth defined in EmailBodyProtocolHandler prepend
stringJS = [NSString stringWithFormat:@"setViewPortWidth(%f);",availableWidth];
[_webView stringByEvaluatingJavaScriptFromString:stringJS];

Additional Tweaking can be done by modifying more of the viewportal content settings:

http://www.htmlgoodies.com/beyond/webmaster/toolbox/article.php/3889591/Detect-and-Set-the-iPhone--iPads-Viewport-Orientation-Using-JavaScript-CSS-and-Meta-Tags.htm

Also, I understand you can put a JS listener for onresize or something like to trigger the rescaling, but this worked for me as I'm doing it from Cocoa Touch UI frameworks.

Hope this helps someone :)

It fails "when trying to execute the function manually" because you have a different 'this'. This will refer not to the thing you have in mind when invoking the method manually, but something else, probably the window object, or whatever context object you have when invoking manually.

The problem with all of the answers given so far is that on the something borrowed site, the Mac bar remains totally hidden when scrolling up, and the provided answers don't accomplish that.

If you just use scrollTo and then the user later scrolls up, the nav bar is revealed again, so it seems you have to put the whole site inside of a div and force scrolling to happen inside of that div rather than on the body which keeps the nav bar hidden during scrolling in any direction.

You can, however, still reveal the nav bar by touching near the top of the screen on apple devices.

To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag.

gcc -c -fPIC hello.c -o hello.o

This will generate an object file (.o), now you take it and create the .so file:

gcc hello.o -shared -o libhello.so

EDIT: Suggestions from the comments:

You can use

gcc -shared -o libhello.so -fPIC hello.c

to do it in one step. – Jonathan Leffler

I also suggest to add -Wall to get all warnings, and -g to get debugging information, to your gcc commands. – Basile Starynkevitch

Check here: http://www.allapplabs.com/java_design_patterns/abstract_factory_pattern.htm it seems that Factory method uses a particular class(not abstract) as a base class while Abstract factory uses an abstract class for this. Also if using an interface instead of abstract class the result will be a different implementation of Abstract Factory pattern.

%timeit is an ipython magic function, which can be used to time a particular piece of code (A single execution statement, or a single method).

From the docs:

%timeit

Time execution of a Python statement or expression

Usage, in line mode:
    %timeit [-n<N> -r<R> [-t|-c] -q -p<P> -o] statement

To use it, for example if we want to find out whether using xrange is any faster than using range, you can simply do:

In [1]: %timeit for _ in range(1000): True
10000 loops, best of 3: 37.8 µs per loop

In [2]: %timeit for _ in xrange(1000): True
10000 loops, best of 3: 29.6 µs per loop

And you will get the timings for them.

The major advantage of %timeit are:

• that you don't have to import timeit.timeit from the standard library, and run the code multiple times to figure out which is the better approach.

• %timeit will automatically calculate number of runs required for your code based on a total of 2 seconds execution window.

• You can also make use of current console variables without passing the whole code snippet as in case of timeit.timeit to built the variable that is built in an another environment that timeit works.

In an existing project a simple way to see the React version is to go to a render method of any component and add:

<p>{React.version}</p>

This assumes you import React like this: import React from 'react'

In Linux you can do like this

pg_dump -U postgres -s postgres > exportFile.dmp

Maybe it can work in Windows too, if not try the same with pg_dump.exe

pg_dump.exe -U postgres -s postgres > exportFile.dmp

Another easier way to do it is to upload your file to google sheets, then add a pivot, for the columns and rows select the same as you would with Excel, however, for values select Calculated Field and then in the formula type in =

Sure, just add & after the command:

read_cfg cfgA &
read_cfg cfgB &
read_cfg cfgC &
wait

all those jobs will then run in the background simultaneously. The optional wait command will then wait for all the jobs to finish.

Each command will run in a separate process, so it's technically not "multithreading", but I believe it solves your problem.

So typically there are two ways to iterate through string in java which has already been answered by multiple people here in this thread, just adding my version of it First is using

String s = sc.next() // assuming scanner class is defined above
for(int i=0; i<s.length; i++){
     s.charAt(i)   // This being the first way and is a constant time operation will hardly add any overhead
  }

char[] str = new char[10];
str = s.toCharArray() // this is another way of doing so and it takes O(n) amount of time for copying contents from your string class to character array

If performance is at stake then I will recommend to use the first one in constant time, if it is not then going with the second one makes your work easier considering the immutability with string classes in java.

You can also use the following syntax

 iptables -D <chain name> <rule number>

For example

Chain HTTPS 
    target     prot opt source               destination
    ACCEPT     all  --  anywhere             anywhere
    ACCEPT     all  --  10.0.0.0/8           anywhere
    ACCEPT     all  --  182.162.0.0/16       anywhere

To delete the rule

ACCEPT all -- 10.0.0.0/8 anywhere

iptables -D HTTPS 2

I've used this to solve my similar problem ... displaying an image counter (from an external provider). It did not refresh always correctly. And after a random parameter was added, all works fine :)

I've appended a date string to ensure refresh at least every minute.

sample code (PHP):

$output .= "<img src=\"http://xy.somecounter.com/?id=1234567890&".date(ymdHi)."\" alt=\"somecounter.com\" style=\"border:none;\">";

That results in a src link like:

http://xy.somecounter.com/?id=1234567890&1207241014

Although currently there is no way to declare a method or property as private, ES6 modules are not in the global namespace. Therefore, anything that you declare in your module and do not export will not be available to any other part of your program, but will still be available to your module during run time. Thus, you have private properties and methods :)

Here is an example (in test.js file)

function tryMe1(a) {
  console.log(a + 2);
}

var tryMe2 = 1234;

class myModule {
  tryMe3(a) {
    console.log(a + 100);
  }

  getTryMe1(a) {
    tryMe1(a);
  }

  getTryMe2() {
    return tryMe2;
  }
}

// Exports just myModule class. Not anything outside of it.
export default myModule; 

In another file

import MyModule from './test';

let bar = new MyModule();

tryMe1(1); // ReferenceError: tryMe1 is not defined
tryMe2; // ReferenceError: tryMe2 is not defined
bar.tryMe1(1); // TypeError: bar.tryMe1 is not a function
bar.tryMe2; // undefined

bar.tryMe3(1); // 101
bar.getTryMe1(1); // 3
bar.getTryMe2(); // 1234

There are two commands which will work in this situation,

root>git reset --hard HEAD~1

root>git push -f

Maybe this is not the answer you needed, but I encountered similar problem, so I decided to put it here.

I needed to convert 500 xml files to UTF8 via Notepad++. Why Notepad++? When I used the option "Encode in UTF8" (many other converters use the same logic) it messed up all special characters, so I had to use "Convert to UTF8" explicitly.

Here some simple steps to convert multiple files via Notepad++ without messing up with special characters (for ex. diacritical marks).

1. Run Notepad++ and then open menu Plugins->Plugin Manager->Show Plugin Manager
2. Install Python Script. When plugin is installed, restart the application.
3. Choose menu Plugins->Python Script->New script.
4. Choose its name, and then past the following code:

convertToUTF8.py

import os
import sys
from Npp import notepad # import it first!

filePathSrc="C:\\Users\\" # Path to the folder with files to convert
for root, dirs, files in os.walk(filePathSrc):
    for fn in files: 
        if fn[-4:] == '.xml': # Specify type of the files
            notepad.open(root + "\\" + fn)      
            notepad.runMenuCommand("Encoding", "Convert to UTF-8")
            # notepad.save()
            # if you try to save/replace the file, an annoying confirmation window would popup.
            notepad.saveAs("{}{}".format(fn[:-4], '_utf8.xml')) 
            notepad.close()

After all, run the script

I know this is quite old, but when a lost stranger finds this question looking for an answer (like I did) then this is the best way to do it, instead of using removeAttr():

$element.prop("onclick", null);

Citing jQuerys official doku:

"Removing an inline onclick event handler using .removeAttr() doesn't achieve the desired effect in Internet Explorer 6, 7, or 8. To avoid potential problems, use .prop() instead"

As many said - this version

int maxAge = context.Persons.Max(p => p.Age);

throws an exception when table is empty.

Use

int maxAge = context.Persons.Max(x => (int?)x.Age) ?? 0;

or

int maxAge = context.Persons.Select(x => x.Age).DefaultIfEmpty(0).Max()

mysqli_affected_rows returns number of items affected.

What you have coded is not a LinkedList, at least not one that I recognize. For this assignment, you want to create two classes:

LinkNode
LinkedList

A LinkNode has one member field for the data it contains, and a LinkNode reference to the next LinkNode in the LinkedList. Yes, it's a self referential data structure. A LinkedList just has a special LinkNode reference that refers to the first item in the list.

When you add an item in the LinkedList, you traverse all the LinkNode's until you reach the last one. This LinkNode's next should be null. You then construct a new LinkNode here, set it's value, and add it to the LinkedList.

public class LinkNode { 

    String data;
    LinkNode next;

    public LinkNode(String item) { 

       data = item;

    }

}

public class LinkedList { 

    LinkNode head;

    public LinkedList(String item) { 

       head = new LinkNode(item);

    }

    public void add(String item) { 

       //pseudo code: while next isn't null, walk the list
       //once you reach the end, create a new LinkNode and add the item to it.  Then
       //set the last LinkNode's next to this new LinkNode

    }


}

Single quotes are escaped by doubling them up, just as you've shown us in your example. The following SQL illustrates this functionality. I tested it on SQL Server 2008:

DECLARE @my_table TABLE (
    [value] VARCHAR(200)
)

INSERT INTO @my_table VALUES ('hi, my name''s tim.')

SELECT * FROM @my_table

Results

value
==================
hi, my name's tim.

If we encapsulate that in a function we could use recursion and state clearly the purpose by naming the function properly (not sure if getAny is actually a good name):

def getAny(dic, keys, default=None):
    return (keys or default) and dic.get(keys[0], 
                                         getAny( dic, keys[1:], default=default))

or even better, without recursion and more clear:

def getAny(dic, keys, default=None):
    for k in keys: 
        if k in dic:
           return dic[k]
    return default

Then that could be used in a way similar to the dict.get method, like:

getAny(myDict, keySet)

and even have a default result in case of no keys found at all:

getAny(myDict, keySet, "not found")

We can't talk about virtual members without referring to polymorphism. In fact, a function, property, indexer or event in a base class marked as virtual will allow override from a derived class.

By default, members of a class are non-virtual and cannot be marked as that if static, abstract, private, or override modifiers.

Example Let's consider the ToString() method in System.Object. Because this method is a member of System.Object it's inherited in all classes and will provide the ToString() methods to all of them.

namespace VirtualMembersArticle
{
    public class Company
    {
        public string Name { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Company company = new Company() { Name = "Microsoft" };
            Console.WriteLine($"{company.ToString()}");
            Console.ReadLine();
        }   
    }
}

The output of the previous code is:

VirtualMembersArticle.Company

Let's consider that we want to change the standard behavior of the ToString() methods inherited from System.Object in our Company class. To achieve this goal it's enough to use the override keyword to declare another implementation of that method.

public class Company
{
    ...
    public override string ToString()
    {
        return $"Name: {this.Name}";
    }         
}

Now, when a virtual method is invoked, the run-time will check for an overriding member in its derived class and will call it if present. The output of our application will then be:

Name: Microsoft

In fact, if you check the System.Object class you will find that the method is marked as virtual.

namespace System
{
    [NullableContextAttribute(2)]
    public class Object
    {
        ....
        public virtual string? ToString();
        ....
    }
}

Ok, I know that I am late to the party here, but I am new to angular. I am trying to make this fit into the John Papa style guide here. I wanted to make this reusable so I created in a block. Here is what I came up with:

previousStateProvider

(function () {
'use strict';

angular.module('blocks.previousState')
       .provider('previousState', previousStateProvider);

previousStateProvider.$inject = ['$rootScopeProvider'];

function previousStateProvider($rootScopeProvider) {
    this.$get = PreviousState;

    PreviousState.$inject = ['$rootScope'];

    /* @ngInject */
    function PreviousState($rootScope) {
        $rootScope.previousParms;
        $rootScope.previousState;
        $rootScope.currentState;

        $rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
            $rootScope.previousParms = fromParams;
            $rootScope.previousState = from.name;
            $rootScope.currentState = to.name;
        });
    }
}
})();

core.module

(function () {
'use strict';

angular.module('myApp.Core', [
    // Angular modules 
    'ngMessages',
    'ngResource',

    // Custom modules 
    'blocks.previousState',
    'blocks.router'

    // 3rd Party Modules
]);
})();

core.config

(function () {
'use strict';

var core = angular.module('myApp.Core');

core.run(appRun);

function appRun(previousState) {
    // do nothing. just instantiating the state handler
}
})();

Any critique on this code will only help me, so please let me know where I can improve this code.

You cannot use var in a field, only on local variables.

But even this won't work:

Site master = Master as Site;

Because you cannot use this in a field and Master as Site is the same as this.Master as Site. So just initialize the field from Page_Init when the page is fully initialized and you can use this:

Site master = null;

protected void Page_Init(object sender, EventArgs e)
{            
    master = this.Master as Site;
}

System.Threading.Thread.Sleep(
    (int)System.TimeSpan.FromSeconds(3).TotalMilliseconds);

Or with using statements:

Thread.Sleep((int)TimeSpan.FromSeconds(2).TotalMilliseconds);

I prefer this to 1000 * numSeconds (or simply 3000) because it makes it more obvious what is going on to someone who hasn't used Thread.Sleep before. It better documents your intent.

I was struggling with a similar problem yesterday. I already had a "working" solution using jQuery UI's draggable together with jQuery Touch Punch, which are mentioned in other answers. However, using this method was causing weird bugs in some Android devices for me, and therefore I decided to write a small jQuery plugin that can make HTML elements draggable by using touch events instead of using a method that emulates fake mouse events.

The result of this is jQuery Draggable Touch which is a simple jQuery plugin for making elements draggable, that has touch devices as it's main target by using touch events (like touchstart, touchmove, touchend, etc.). It still has a fallback that uses mouse events if the browser/device doesn't support touch events.

I think its already been answered before, but just a correction if you are populating an unordered list, the *ngFor will come in the element which you want to repeat. So it should be insdide <li>. Also, Angular2 now uses let to declare a variable.

<ul>
    <li *ngFor="let item of items; let i = index" [attr.data-index]="i">     
               {{item}}
    </li>
</ul>

Use jQuery DataTables plug-in, it supports fixed header and columns. This example adds fixed column support to the html table "example":

http://datatables.net/extensions/fixedcolumns/

For two fixed columns:

http://www.datatables.net/release-datatables/extensions/FixedColumns/examples/two_columns.html

For latest RN versions, you can use this native module: https://github.com/luggit/react-native-config

I've been fighting with this for quite a while. Since this is the first hit on Google when I searched for the solution, let me post where I've gotten so far.

SET @d := '2011-09-01';
SELECT @d AS d, cast( @d := DATE_ADD( @d , INTERVAL 1 DAY ) AS DATE ) AS new_d
  FROM [yourTable]
  WHERE @d <= '2012-05-01';

Replace [yourTable] with a table from your database. The trick is that the number of rows in the table you select must be >= the number of dates you want to be returned. I tried using the table placeholder DUAL, but it would only return one single row.

There is no way (to my knowledge) to trigger the download window in your browser from Javascript. The only way to do it is to redirect the browser to a url that streams the file to the browser.

If you can modify your REST service, you might be able to solve it by changing so the POST request doesn't respond with the binary file, but with a url to that file. That'll get you the url in Javascript instead of the binary data, and you can redirect the browser to that url, which should prompt the download without leaving the original page.

If you haven't already committed your changes, just use git checkout to move to the new branch and then commit them normally - changes to files are not tied to a particular branch until you commit them.

If you have already committed your changes:

1. Type git log and remember the SHA of the commit you want to move.
2. Check out the branch you want to move the commit to.
3. Type git cherry-pick SHA substituting the SHA from above.
4. Switch back to your original branch.
5. Use git reset HEAD~1 to reset back before your wrong-branch commit.

cherry-pick takes a given commit and applies it to the currently checked-out head, thus allowing you to copy the commit over to a new branch.

There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.

If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.

Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.

Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.

You can use theme_get() to display the possible options for theme. You can control the legend font size using:

+ theme(legend.text=element_text(size=X))

replacing X with the desired size.

The default constructor has no arguments. You need to specify a constructor:

    public Friends( String firstName, String age) { ... }

Here are the current past AngularJS incantations:

angular.module('SharedServices', [])
    .config(function ($httpProvider) {
        $httpProvider.responseInterceptors.push('myHttpInterceptor');
        var spinnerFunction = function (data, headersGetter) {
            // todo start the spinner here
            //alert('start spinner');
            $('#mydiv').show();
            return data;
        };
        $httpProvider.defaults.transformRequest.push(spinnerFunction);
    })
// register the interceptor as a service, intercepts ALL angular ajax http calls
    .factory('myHttpInterceptor', function ($q, $window) {
        return function (promise) {
            return promise.then(function (response) {
                // do something on success
                // todo hide the spinner
                //alert('stop spinner');
                $('#mydiv').hide();
                return response;

            }, function (response) {
                // do something on error
                // todo hide the spinner
                //alert('stop spinner');
                $('#mydiv').hide();
                return $q.reject(response);
            });
        };
    });

//regular angular initialization continued below....
angular.module('myApp', [ 'myApp.directives', 'SharedServices']).
//.......

Here is the rest of it (HTML / CSS)....using

$('#mydiv').show(); 
$('#mydiv').hide(); 

to toggle it. NOTE: the above is used in the angular module at beginning of post

#mydiv {  
    position:absolute;
    top:0;
    left:0;
    width:100%;
    height:100%;
    z-index:1000;
    background-color:grey;
    opacity: .8;
 }

.ajax-loader {
    position: absolute;
    left: 50%;
    top: 50%;
    margin-left: -32px; /* -1 * image width / 2 */
    margin-top: -32px;  /* -1 * image height / 2 */
    display: block;     
}

<div id="mydiv">
    <img src="lib/jQuery/images/ajax-loader.gif" class="ajax-loader"/>
</div>

One way of doing it is to use the ClientScriptManager:

Page.ClientScript.RegisterStartupScript(
    GetType(), 
    "MyKey", 
    "Myfunction();", 
    true);

try this.

python -m  pip ...

-m module-name Searches sys.path for the named module and runs the corresponding .py file as a script.

Sometimes the OS can't find pip so python or py -m may solve the problem because it is python itself searching for pip.

I believe that by now the above answers are outdated (or at least unclear) so here's my little go at it. I tried compiling ffmpeg with the option --enable-encoders=libx264 and it will give no error but it won't enable anything (I can't seem to find where I found that suggestion).

Anyways step-by-step, first you must compile libx264 yourself because repository version is outdated:

  wget ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
  tar --bzip2 -xvf last_x264.tar.bz2
  cd x264-snapshot-XXXXXXXX-XXXX/
  ./configure
  make
  sudo make install

And then get and compile ffmpeg with libx264 enabled. I'm using the latest release which is "Happiness":

wget http://ffmpeg.org/releases/ffmpeg-0.11.2.tar.bz2
tar --bzip2 -xvf ffmpeg-0.11.2.tar.bz2
cd ffmpeg-0.11.2/
./configure --enable-libx264 --enable-gpl
make
sudo install

Now finally you have the libx264 codec to encode, to check it you may run

ffmpeg -codecs | grep h264

and you'll see the options you have were the first D means decoding and the first E means encoding

It wouldn't be wrong to mention that Pexpect does throw a similar error

#python -c "import pexpect; p=pexpect.spawn('/usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/pexpect.py", line 430, in __init__
    self._spawn (command, args)
  File "/usr/lib/python2.7/site-packages/pexpect.py", line 560, in _spawn
    os.execv(self.command, self.args)
OSError: [Errno 8] Exec format error

Over here, the openssl_1.1.0f file at the specified path has exec command specified in it and is running the actual openssl binary when called.

Usually, I wouldn't mention this unless I have the root cause, but this problem was not there earlier. Unable to find the similar problem, the closest explanation to make it work is the same as the one provided by @jfs above.

what worked for me is both

• adding /bin/bash at the beginning of the command or file you are
  facing the problem with, or
• adding shebang #!/bin/sh as the first line.

for ex.

#python -c "import pexpect; p=pexpect.spawn('/bin/bash /usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
OpenSSL 1.1.0f  25 May 2017

OK so I think i know the issue you're having.

Basically, because Composer can't see the migration files you are creating, you are having to run the dump-autoload command which won't download anything new, but looks for all of the classes it needs to include again. It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php), and this is why your migration is working after you run that command.

How to fix it (possibly) You need to add some extra information to your composer.json file.

"autoload": {
    "classmap": [
        "PATH TO YOUR MIGRATIONS FOLDER"
    ],
}

You need to add the path to your migrations folder to the classmap array. Then run the following three commands...

php artisan clear-compiled 
composer dump-autoload
php artisan optimize

This will clear the current compiled files, update the classes it needs and then write them back out so you don't have to do it again.

Ideally, you execute composer dump-autoload -o , for a faster load of your webpages. The only reason it is not default, is because it takes a bit longer to generate (but is only slightly noticable).

Hope you can manage to get this sorted, as its very annoying indeed :(

2 key advantages of SVN that are rarely cited:

1. Large file support. In addition to code, I use SVN to manage my home directory. SVN is the only VCS (distributed or not) that doesn't choke on my TrueCrypt files (please correct me if there's another VCS that handles 500MB+ files effectively). This is because diff comparisons are streamed (this is a very essential point). Rsync is unacceptable because it's not 2-way.

2. Partial repository (subdir) checkout/checkin. Mercurial and bzr don't support this, and git's support is limited. This is bad in a team environment, but invaluable if I want to check something out on another computer from my home dir.

Just my experiences.

I'll cover each point separately.

1. Some evil code may steal your lock (very popular this one, also has an "accidentally" variant)

   I'm more worried about accidentally. What it amounts to is that this use of this is part of your class' exposed interface, and should be documented. Sometimes the ability of other code to use your lock is desired. This is true of things like Collections.synchronizedMap (see the javadoc).

2. All synchronized methods within the same class use the exact same lock, which reduces throughput

   This is overly simplistic thinking; just getting rid of synchronized(this) won't solve the problem. Proper synchronization for throughput will take more thought.

3. You are (unnecessarily) exposing too much information

   This is a variant of #1. Use of synchronized(this) is part of your interface. If you don't want/need this exposed, don't do it.

SELECT DATEDIFF(NOW(),pickup_date) AS noofday 
FROM cir_order 
WHERE DATEDIFF(NOW(),pickup_date)>2;

or

SELECT * 
FROM cir_order 
WHERE cir_order.`cir_date` >= DATE_ADD( CURDATE(), INTERVAL -10 DAY )

You could also use XPCOM, say in XUL based apps like Firefox, Thunderbird or Komodo.

Use a format string to round up to two decimal places and convert the double to a String:

let currentRatio = Double (rxCurrentTextField.text!)! / Double (txCurrentTextField.text!)!
railRatioLabelField.text! = String(format: "%.2f", currentRatio)

Example:

let myDouble = 3.141
let doubleStr = String(format: "%.2f", myDouble) // "3.14"

If you want to round up your last decimal place, you could do something like this (thanks Phoen1xUK):

let myDouble = 3.141
let doubleStr = String(format: "%.2f", ceil(myDouble*100)/100) // "3.15"

I solved this problem on my Galaxy S4 phone by replacing context.startActivity(addAccountIntent); with startActivity(new Intent(Settings.ACTION_ADD_ACCOUNT));

You can use a $ sign like:

OUTPUT=$(expression)

DTO vs VO

DTO - Data transfer objects are just data containers which are used to transport data between layers and tiers.

• It mainly contains attributes. You can even use public attributes without getters and setters.
• Data transfer objects do not contain any business logic.

Analogy:
Simple Registration form with attributes username, password and email id.

• When this form is submitted in RegistrationServlet file you will get all the attributes from view layer to business layer where you pass the attributes to java beans and then to the DAO or the persistence layer.
• DTO's helps in transporting the attributes from view layer to business layer and finally to the persistence layer.

DTO was mainly used to get data transported across the network efficiently, it may be even from JVM to another JVM.

DTOs are often java.io.Serializable - in order to transfer data across JVM.

VO - A Value Object [1][2] represents itself a fixed set of data and is similar to a Java enum. A Value Object's identity is based on their state rather than on their object identity and is immutable. A real world example would be Color.RED, Color.BLUE, SEX.FEMALE etc.

POJO vs JavaBeans

[1] The Java-Beanness of a POJO is that its private attributes are all accessed via public getters and setters that conform to the JavaBeans conventions. e.g.

    private String foo;
    public String getFoo(){...}
    public void setFoo(String foo){...}; 

[2] JavaBeans must implement Serializable and have a no-argument constructor, whereas in POJO does not have these restrictions.

Programmatically: Run time

You can do programmatically using setTypeface():

textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
textView.setTypeface(null, Typeface.BOLD);        // for Bold only
textView.setTypeface(null, Typeface.ITALIC);      // for Italic
textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic

XML: Design Time

You can set in XML as well:

android:textStyle="normal"
android:textStyle="normal|bold"
android:textStyle="normal|italic"
android:textStyle="bold"
android:textStyle="bold|italic"

Hope this will help

In Chrome & Firefox (+31) you can add CSS in console.log messages:

console.log('%c Oh my heavens! ', 'background: #222; color: #bada55');

The same can be applied for adding multiple CSS to same command.

UPDATE:

After misunderstanding, I finally got what you are trying to do. You should check your server configuration files; are you using apache2 or some other server software?

Look for lines that start with LoadModule php... There probably are configuration files/directories named mods or something like that, start from there.

You could also check output from php -r 'phpinfo();' | grep php and compare lines to phpinfo(); from web server.

To run php interactively:

(so you can paste/write code in the console)

php -a

To make it parse file and output to console:

php -f file.php

Parse file and output to another file:

php -f file.php > results.html

Do you need something else?

To run only small part, one line or like, you can use:

php -r '$x = "Hello World"; echo "$x\n";'

If you are running linux then do man php at console.

if you need/want to run php through fpm, use cli fcgi

SCRIPT_NAME="file.php" SCRIP_FILENAME="file.php" REQUEST_METHOD="GET" cgi-fcgi -bind -connect "/var/run/php-fpm/php-fpm.sock"

where /var/run/php-fpm/php-fpm.sock is your php-fpm socket file.

An easy way to do:

function toggleButton(ref,bttnID){
    document.getElementById(bttnID).disabled= ((ref.value !== ref.defaultValue) ? false : true);
}


<input ... onkeyup="toggleButton(this,'bttnsubmit');">
<input ... disabled='disabled' id='bttnsubmit' ... >

You need to float all the buttons to left and make sure its width to fit within outer container.

CSS:

.btn{

   float:left;
}

HTML:

    <button type="submit" class="btn" onClick="return false;" >Save</button>
    <button type="submit" class="btn" onClick="return false;">Publish</button>
    <button class="btn">Back</button>

Hello this is best sample demo app which provides facebook like slide menu. Check the code here

You can check undefined object using below code.

ReactObject === 'undefined'

Following code will generate a random sample of size 4:

import random

sample_size = 4
sorted_sample = [
    mylist[i] for i in sorted(random.sample(range(len(mylist)), sample_size))
]

(note: with Python 2, better use xrange instead of range)

Explanation

random.sample(range(len(mylist)), sample_size)

generates a random sample of the indices of the original list.

These indices then get sorted to preserve the ordering of elements in the original list.

Finally, the list comprehension pulls out the actual elements from the original list, given the sampled indices.

Easy, just find the location where keytool executable is, normally is in java/jre(Version)/bin forexample in my computer is in C:\Program Files\Java\jre7\bin. all you have to do is go to environment variables, click PATH to make it active, then click edit, then add complete path where your keytool is, for me i will add C:\Program Files\Java\jre7\bin this will allow you to execute keytool commands without going to the directory where keytool is installed.

I sometimes have this same problem. VSCode will just suddenly lose it's mind and completely ignore any indentation setting I tell it, even though it's been indenting the same file just fine all day.

I have editor.tabSize set to 2 (as well as editor.formatOnSave set to true). When VSCode messes up a file, I use the options at the bottom of the editor to change indentation type and size, hoping something will work, but VSCode insists on actually using an indent size of 4.

The fix? Restart VSCode. It should come back with the indent status showing something wrong (in my case, 4). For me, I had to change the setting and then save for it to actually make the change, but that's probably because of my editor.formatOnSave setting.

I haven't figured out why it happens, but for me it's usually when I'm editing a nested object in a JS file. It will suddenly do very strange indentation within the object, even though I've been working in that file for a while and it's been indenting just fine.

You realise that you may be making a rod for your own back for the future. The pwdencrypt() and pwdcompare() are undocumented functions and may not behave the same in future versions of SQL Server.

Why not hash the password using a predictable algorithm such as SHA-2 or better before hitting the DB?

So you know the key, value pair that you want to delete in advance? It's just much clearer to do this, then:

 table.delete(key);
 for (K key: table.keySet()) {
    // do whatever you need to do with the rest of the keys
 }

Ok. I found a program buried deep in other files from the beginning of the year that does what I want. I can't really comment on the suggestions offered because I'm not an experienced spim or low level programmer.Here it is:

         .text
         .globl __start
    __start:
         la $a0,str1 #Load and print string asking for string
         li $v0,4
         syscall

         li $v0,8 #take in input
         la $a0, buffer #load byte space into address
         li $a1, 20 # allot the byte space for string
         move $t0,$a0 #save string to t0
         syscall

         la $a0,str2 #load and print "you wrote" string
         li $v0,4
         syscall

         la $a0, buffer #reload byte space to primary address
         move $a0,$t0 # primary address = t0 address (load pointer)
         li $v0,4 # print string
         syscall

         li $v0,10 #end program
         syscall


               .data
             buffer: .space 20
             str1:  .asciiz "Enter string(max 20 chars): "
             str2:  .asciiz "You wrote:\n"
             ###############################

getClass().getResource() uses the class loader to load the resource. This means that the resource must be in the classpath to be loaded.

When doing it with Eclipse, everything you put in the source folder is "compiled" by Eclipse:

• .java files are compiled into .class files that go the the bin directory (by default)
• other files are copied to the bin directory (respecting the package/folder hirearchy)

When launching the program with Eclipse, the bin directory is thus in the classpath, and since it contains the Test.properties file, this file can be loaded by the class loader, using getResource() or getResourceAsStream().

If it doesn't work from the command line, it's thus because the file is not in the classpath.

Note that you should NOT do

FileInputStream inputStream = new FileInputStream(new File(getClass().getResource(url).toURI()));

to load a resource. Because that can work only if the file is loaded from the file system. If you package your app into a jar file, or if you load the classes over a network, it won't work. To get an InputStream, just use

getClass().getResourceAsStream("Test.properties")

And finally, as the documentation indicates,

Foo.class.getResourceAsStream("Test.properties")

will load a Test.properties file located in the same package as the class Foo.

Foo.class.getResourceAsStream("/com/foo/bar/Test.properties")

will load a Test.properties file located in the package com.foo.bar.

Unfortunately, it seems that pm2 doesn't support the exact functionality you requested https://github.com/Unitech/PM2/issues/1317.

The alternative proposed is to use a ecosystem.json file Getting started with deployment which could include setups for production and dev environments. However, this is still using npm start to bootstrap your app.

$( this ).find( 'li.target' ).css("border", "3px double red");

or

$( this ).children( 'li.target' ).css("border", "3px double red");

Use children for immediate descendants, or find for deeper elements.

• Earlier in iOS 7.0–11.0 <Deprecated> UIKit uses the topLayoutGuide & bottomLayoutGuide which is UIView property

• iOS11+ uses safeAreaLayoutGuide which is also UIView property

• Enable Safe Area Layout Guide check box from file inspector.

• Safe areas help you place your views within the visible portion of the overall interface.

• In tvOS, the safe area also includes the screen’s overscan insets, which represent the area covered by the screen’s bezel.

• safeAreaLayoutGuide reflects the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor viewss.

• Use safe areas as an aid to laying out your content like UIButton etc.

• When designing for iPhone X, you must ensure that layouts fill the screen and aren't obscured by the device's rounded corners, sensor housing, or the indicator for accessing the Home screen.

• Make sure backgrounds extend to the edges of the display, and that vertically scrollable layouts, like tables and collections, continue all the way to the bottom.

• The status bar is taller on iPhone X than on other iPhones. If your app assumes a fixed status bar height for positioning content below the status bar, you must update your app to dynamically position content based on the user's device. Note that the status bar on iPhone X doesn't change height when background tasks like voice recording and location tracking are active print(UIApplication.shared.statusBarFrame.height)//44 for iPhone X, 20 for other iPhones

• Height of home indicator container is 34 points.

• Once you enable Safe Area Layout Guide you can see safe area constraints property listed in the interface builder.

You can set constraints with respective of self.view.safeAreaLayoutGuide as-

ObjC:

  self.demoView.translatesAutoresizingMaskIntoConstraints = NO;
    UILayoutGuide * guide = self.view.safeAreaLayoutGuide;
    [self.demoView.leadingAnchor constraintEqualToAnchor:guide.leadingAnchor].active = YES;
    [self.demoView.trailingAnchor constraintEqualToAnchor:guide.trailingAnchor].active = YES;
    [self.demoView.topAnchor constraintEqualToAnchor:guide.topAnchor].active = YES;
    [self.demoView.bottomAnchor constraintEqualToAnchor:guide.bottomAnchor].active = YES;

Swift:

   demoView.translatesAutoresizingMaskIntoConstraints = false
        if #available(iOS 11.0, *) {
            let guide = self.view.safeAreaLayoutGuide
            demoView.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
            demoView.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
            demoView.bottomAnchor.constraint(equalTo: guide.bottomAnchor).isActive = true
            demoView.topAnchor.constraint(equalTo: guide.topAnchor).isActive = true
        } else {
            NSLayoutConstraint(item: demoView, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: demoView, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: demoView, attribute: .bottom, relatedBy: .equal, toItem: view, attribute: .bottom, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: demoView, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 0).isActive = true
        }

Try to get using:

var count = $("ul > li").size();
alert(count);

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

I had to use the install function instead:

conda install pandas=0.13.1

Maven setup:

a. install maven from https://maven.apache.org/download.cgi

b. unzip maven and keep in C drive.

c. Set MAVEN_HOME in system variable.

d. Set path for maven

For VB6:

You need to declare your C functions as __stdcall, otherwise you get "invalid calling convention" type errors. About other your questions:

can I take arguments by pointer/reference from the VB front-end?

Yes, use ByRef/ByVal modifiers.

Can the DLL call a theoretical function in the front-end?

Yes, use AddressOf statement. You need to pass function pointer to dll before.

Or have a function take a "function pointer" (I don't even know if that's possible) from VB and call it?)

Yes, use AddressOf statement.

update (more questions appeared :)):

to load it into VB, do I just do the usual method (what I would do to load winsock.ocx or some other runtime, but find my DLL instead) or do I put an API call into a module?

You need to decaler API function in VB6 code, like next:

Private Declare Function SHGetSpecialFolderLocation Lib "shell32" _
   (ByVal hwndOwner As Long, _
    ByVal nFolder As Long, _
    ByRef pidl As Long) As Long

Reference the checkbox by it's id and not with the # Assign the function to the onclick attribute rather than using the change attribute

var checkbox = $("save_" + fieldName);
checkbox.onclick = function(event) {
    var checkbox = event.target;

    if (checkbox.checked) {
        //Checkbox has been checked
    } else {
        //Checkbox has been unchecked
    }
};

Simply saying, any() does this work : according to the condition even if it encounters one fulfilling value in the list, it returns true, else it returns false.

list = [2,-3,-4,5,6]

a = any(x>0 for x in lst)

print a:
True


list = [2,3,4,5,6,7]

a = any(x<0 for x in lst)

print a:
False

In the module build.gradle, in the task field, I get an error unless I use:

def ndkDir = plugins.getPlugin('com.android.application').sdkHandler.getNdkFolder()

I see people using

def ndkDir = android.plugin.ndkFolder

and

def ndkDir = plugins.getPlugin('com.android.library').sdkHandler.getNdkFolder()

but neither of those worked until I changed it to the plugin I was actually importing.

Try this, it's simple and clear. I have found it from here : https://css-tricks.com/tinted-images-multiple-backgrounds/

You can make the following sql query

IF ((SELECT COUNT(*) FROM table1 WHERE project = 1) > 0) 
    SELECT product, price FROM table1 WHERE project = 1
ELSE IF ((SELECT COUNT(*) FROM table1 WHERE project = 2) > 0) 
    SELECT product, price FROM table1 WHERE project = 2
ELSE IF ((SELECT COUNT(*) FROM table1 WHERE project = 3) > 0)
    SELECT product, price FROM table1 WHERE project = 3

It actually tells you what's wrong, but you ignored it because you didn't check the error returned from json.Marshal.

json: unsupported type: map[int]main.Foo

JSON spec doesn't support anything except strings for object keys, while javascript won't be fussy about it, it's still illegal.

You have two options:

1 Use map[string]Foo and convert the index to string (using fmt.Sprint for example):

datas := make(map[string]Foo, N)

for i := 0; i < 10; i++ {
    datas[fmt.Sprint(i)] = Foo{Number: 1, Title: "test"}
}
j, err := json.Marshal(datas)
fmt.Println(string(j), err)

2 Simply just use a slice (javascript array):

datas2 := make([]Foo, N)
for i := 0; i < 10; i++ {
    datas2[i] = Foo{Number: 1, Title: "test"}
}
j, err = json.Marshal(datas2)
fmt.Println(string(j), err)

Taking @maxyfc's answer further, I needed to find all of the rows that were returned with the duplicate values, so I could edit them in MySQL Workbench:

SELECT * FROM table
   WHERE field IN (
     SELECT field FROM table GROUP BY field HAVING count(*) > 1
   ) ORDER BY field

You need to enclose that in <%! %> as follows:

<%!

public String getQuarter(int i){
String quarter;
switch(i){
        case 1: quarter = "Winter";
        break;

        case 2: quarter = "Spring";
        break;

        case 3: quarter = "Summer I";
        break;

        case 4: quarter = "Summer II";
        break;

        case 5: quarter = "Fall";
        break;

        default: quarter = "ERROR";
}

return quarter;
}

%>

You can then invoke the function within scriptlets or expressions:

<%
     out.print(getQuarter(4));
%>

or

<%= getQuarter(17) %>

String value = "{first_name = naresh,last_name = kumar,gender = male}"

Let's start

1. Remove { and } from the String>>first_name = naresh,last_name = kumar,gender = male
2. Split the String from ,>> array of 3 element
3. Now you have an array with 3 element
4. Iterate the array and split each element by =
5. Create a Map<String,String> put each part separated by =. first part as Key and second part as Value

I found that when you use the action buttons in expanded notifications, you have to write extra code and you are more constrained.

You have to manually cancel your notification when the user clicks an action button. The notification is only cancelled automatically for the default action.

Also if you start a broadcast receiver from the button, the notification drawer doesn't close.

I ended up creating a new NotificationActivity to address these issues. This intermediary activity without any UI cancels the notification and then starts the activity I really wanted to start from the notification.

I've posted sample code in a related post Clicking Android Notification Actions does not close Notification drawer.

next((x for x in test_list if x.value == value), None)

This gets the first item from the list that matches the condition, and returns None if no item matches. It's my preferred single-expression form.

However,

for x in test_list:
    if x.value == value:
        print("i found it!")
        break

The naive loop-break version, is perfectly Pythonic -- it's concise, clear, and efficient. To make it match the behavior of the one-liner:

for x in test_list:
    if x.value == value:
        print("i found it!")
        break
else:
    x = None

This will assign None to x if you don't break out of the loop.

Yes, it is correct. Its just a helper function to have a simpler way to access your state properties

Imagine you have a posts key in your App state.posts

state.posts //
/*    
{
  currentPostId: "",
  isFetching: false,
  allPosts: {}
}
*/

And component Posts

By default connect()(Posts) will make all state props available for the connected Component

const Posts = ({posts}) => (
  <div>
    {/* access posts.isFetching, access posts.allPosts */}
  </div> 
)

Now when you map the state.posts to your component it gets a bit nicer

const Posts = ({isFetching, allPosts}) => (
  <div>
    {/* access isFetching, allPosts directly */}
  </div> 
)

connect(
  state => state.posts
)(Posts)

mapDispatchToProps

normally you have to write dispatch(anActionCreator())

with bindActionCreators you can do it also more easily like

connect(
  state => state.posts,
  dispatch => bindActionCreators({fetchPosts, deletePost}, dispatch)
)(Posts)

Now you can use it in your Component

const Posts = ({isFetching, allPosts, fetchPosts, deletePost }) => (
  <div>
    <button onClick={() => fetchPosts()} />Fetch posts</button>
    {/* access isFetching, allPosts directly */}
  </div> 
)

Update on actionCreators..

An example of an actionCreator: deletePost

const deletePostAction = (id) => ({
  action: 'DELETE_POST',
  payload: { id },
})

So, bindActionCreators will just take your actions, wrap them into dispatch call. (I didn't read the source code of redux, but the implementation might look something like this:

const bindActionCreators = (actions, dispatch) => {
  return Object.keys(actions).reduce(actionsMap, actionNameInProps => {
    actionsMap[actionNameInProps] = (...args) => dispatch(actions[actionNameInProps].call(null, ...args))
    return actionsMap;
  }, {})
}

I was having this same problem and found the solution in the anwser to another question: https://stackoverflow.com/a/1951132/425749

Basically, installing CDT does not install a compiler, and Eclipse's error messages are not explicit about this.

Why not:

public class MyClass
{
    private Dictionary<string, int> _myCollection = new Dictionary<string, int>() { { "A", 1 }, { "B", 2 }, { "C", 3 } };

    public IEnumerable<KeyValuePair<string,int>> MyCollection
    {
        get { return _myCollection.AsEnumerable<KeyValuePair<string, int>>(); }
    }
}

Recent versions of hive comes with this feature.

INSERT OVERWRITE LOCAL DIRECTORY '/home/lvermeer/temp' 
ROW FORMAT DELIMITED 
FIELDS TERMINATED BY ',' 
select * from table;

this way you can choose your own delimiter and file name. Just be careful with the "OVERWRITE" it will try to delete everything from the mentioned folder.

Came across this question just now and have something to add

To go to the most recent commit:

git checkout $(git log --branches -1 --pretty=format:"%H")

Explanation:

git log --branches shows log of commits from all local branches
-1 limit to one commit → most recent commit
--pretty=format:"%H" format to only show commit hash
git checkout $(...) use output of subshell as argument for checkout

Note:

This will result in a detached head though (because we checkout directly to the commit). This can be avoided by extracting the branch name using sed, explained below.

To go to the branch of the most recent commit:

git checkout $(git log --branches -1 --pretty=format:'%D' | sed 's/.*, //g')

Explanation:

git log --branches shows log of commits from all local branches
-1 limit to one commit → most recent commit
--pretty=format:"%D" format to only show ref names
| sed 's/.*, //g' ignore all but the last of multiple refs (*)
git checkout $(...) use output of subshell as argument for checkout

*) HEAD and remote branches are listed first, local branches are listed last in alphabetically descending order, so the one remaining will be the alphabetically first branch name

Note:

This will always only use the (alphabetically) first branch name if there are multiple for that commit.

Anyway, I think the best solution would just be to display the ref names for the most recent commit to know where to checkout to:

git log --branches -1 --pretty=format:'%D'

E.g. create the alias git top for that command.

1. You should install ALL dependencies:

   sudo apt-get install build-essential python3-dev python3-setuptools python3-numpy python3-scipy libatlas-dev libatlas3gf-base

2. Install pip3(if you have installed, please look step 3):

   sudo apt-get install python3-pip

3. Iinstall scikit-learn by pip3

   pip3 install -U scikit-learn

4. Open your terminal and entry python3 environment, type import sklearn to check it.

Gook Luck!

You can use this script. http://pellepim.bitbucket.org/jstz/

Fork or clone repository here. https://bitbucket.org/pellepim/jstimezonedetect

Once you include the script, you can get the list of timezones in - jstz.olson.timezones variable.

And following code is used to determine client browser's timezone.

var tz = jstz.determine();
tz.name();

Enjoy jstz!

Simply put, you need to rewrite all of your database connections and queries.

You are using mysql_* functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.

A basic example of using PDO (without error handling):

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>

A basic example of using MySQLi (without error handling):

$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");

Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.

Best way is to Use a Python Web Frame Work you can choose Django/Flask. I will suggest you to Use Django because it's more powerful. Here is Step by guide to get complete your task :

pip install django
django-admin createproject buttonpython

then you have to create a file name views.py in buttonpython directory.

write below code in views.py:

from django.http import HttpResponse

def sample(request):
    #your python script code
    output=code output
    return HttpResponse(output)

Once done navigate to urls.py and add this stanza

from . import views

path('', include('blog.urls')),

Now go to parent directory and execute manage.py

python manage.py runserver 127.0.0.1:8001

There is a good stackoverflow answer here by Mark Rajcok:

AngularJS directive controllers requiring parent directive controllers?

with a link to this very clear jsFiddle: http://jsfiddle.net/mrajcok/StXFK/

<div ng-controller="MyCtrl">
    <div screen>
        <div component>
            <div widget>
                <button ng-click="widgetIt()">Woo Hoo</button>
            </div>
        </div>
    </div>
</div>

JavaScript

var myApp = angular.module('myApp',[])

.directive('screen', function() {
    return {
        scope: true,
        controller: function() {
            this.doSomethingScreeny = function() {
                alert("screeny!");
            }
        }
    }
})

.directive('component', function() {
    return {
        scope: true,
        require: '^screen',
        controller: function($scope) {
            this.componentFunction = function() {
                $scope.screenCtrl.doSomethingScreeny();
            }
        },
        link: function(scope, element, attrs, screenCtrl) {
            scope.screenCtrl = screenCtrl
        }
    }
})

.directive('widget', function() {
    return {
        scope: true,
        require: "^component",
        link: function(scope, element, attrs, componentCtrl) {
            scope.widgetIt = function() {
                componentCtrl.componentFunction();
            };
        }
    }
})


//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});

function MyCtrl($scope) {
    $scope.name = 'Superhero';
}

use the JavaScript Date() object. There are a number of ways to get the time, date, timestamps, etc from the object. (Reference)

function myFunction() {
  var d = new Date();
  var timeStamp = d.getTime();  // Number of ms since Jan 1, 1970

  // OR:

  var currentTime = d.toLocaleTimeString(); // "12:35 PM", for instance
}

Personally, I'd go for a solution like this, it's incredibly similar to the solution provided by @rzwitserloot, only subtle differences.

This solution is small, simple & clean, it requires very little in terms of dependencies, all of which are a part of the Java Util package.

Map<String, String> map = new HashMap<>();

map.put("param1", "12");
map.put("param2", "cat");

String output = "someUrl?";
output += map.entrySet()
    .stream()
    .map(x -> x.getKey() + "=" + x.getValue() + "&")
    .collect(Collectors.joining("&"));

System.out.println(output.substring(0, output.length() -1));

As I know, PDO_MYSQLND replaced PDO_MYSQL in PHP 5.3. Confusing part is that name is still PDO_MYSQL. So now ND is default driver for MySQL+PDO.

Overall, to execute multiple queries at once you need:

• PHP 5.3+
• mysqlnd
• Emulated prepared statements. Make sure PDO::ATTR_EMULATE_PREPARES is set to 1 (default). Alternatively you can avoid using prepared statements and use $pdo->exec directly.

Using exec

$db = new PDO("mysql:host=localhost;dbname=test", 'root', '');

// works regardless of statements emulation
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, 0);

$sql = "
DELETE FROM car; 
INSERT INTO car(name, type) VALUES ('car1', 'coupe'); 
INSERT INTO car(name, type) VALUES ('car2', 'coupe');
";

$db->exec($sql);

Using statements

$db = new PDO("mysql:host=localhost;dbname=test", 'root', '');

// works not with the following set to 0. You can comment this line as 1 is default
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, 1);

$sql = "
DELETE FROM car; 
INSERT INTO car(name, type) VALUES ('car1', 'coupe'); 
INSERT INTO car(name, type) VALUES ('car2', 'coupe');
";

$stmt = $db->prepare($sql);
$stmt->execute();

A note:

When using emulated prepared statements, make sure you have set proper encoding (that reflects actual data encoding) in DSN (available since 5.3.6). Otherwise there can be a slight possibility for SQL injection if some odd encoding is used.

I use zsh and Android Studio. I use a variable for my Android SDK path and configure in the file ~/.zshrc:

export ANDROID_HOME=/Applications/Android\ Studio.app/sdk
export PATH="$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools:$PATH"

Note: Make sure not to include single or double quotes around the specified path. If you do, it won't work.

Support for OFFSET and LIMIT was recently added to DB2 for i 7.1 and 7.2. You need the following DB PTF group levels to get this support:

• SF99702 level 9 for IBM i 7.2
• SF99701 level 38 for IBM i 7.1

See here for more information: OFFSET and LIMIT documentation, DB2 for i Enhancement Wiki

The Answer

Just use TheClassName.class instead of getClass().

Declaring Loggers

Since this gets so much attention for a specific usecase--to provide an easy way to insert log declarations--I thought I'd add my thoughts on that. Log frameworks often expect the log to be constrained to a certain context, say a fully-qualified class name. So they are not copy-pastable without modification. Suggestions for paste-safe log declarations are provided in other answers, but they have downsides such as inflating bytecode or adding runtime introspection. I don't recommend these. Copy-paste is an editor concern, so an editor solution is most appropriate.

In IntelliJ, I recommend adding a Live Template:

• Use "log" as the abbreviation
• Use private static final org.slf4j.Logger logger = org.slf4j.LoggerFactory.getLogger($CLASS$.class); as the template text.
• Click Edit Variables and add CLASS using the expression className()
• Check the boxes to reformat and shorten FQ names.
• Change the context to Java: declaration.

Now if you type log<tab> it'll automatically expand to

private static final Logger logger = LoggerFactory.getLogger(ClassName.class);

And automatically reformat and optimize the imports for you.

You have a List<string> - so if you want them concatenated, something like

string s = string.Join("", list);

would work (in .NET 4.0 at least). The first parameter is the delimiter. So you could also comma-delimit etc.

You might also want to look at using StringBuilder to do running concatenations, rather than forming a list.

same from above example - if you are just looking for json (not an array of object) just use

function getJsonDetails() {
      item = {}
      item ["token1"] = token1val;
      item ["token2"] = token1val;
      return item;
}
console.log(JSON.stringify(getJsonDetails()))

this output ll print as (a valid json)

{ 
   "token1":"samplevalue1",
   "token2":"samplevalue2"
}

if one row has value in field1 column and other rows have null value then this Query might work.

SELECT
  FK,
  MAX(Field1) as Field1,
  MAX(Field2) as Field2
FROM 
(
select FK,ISNULL(Field1,'') as Field1,ISNULL(Field2,'') as Field2 from table1
)
tbl
GROUP BY FK

You need to use a date formatting function for example to_char http://www.postgresql.org/docs/current/static/functions-formatting.html

There's a Python3 pip package called githubdl that can do this*:

export GIT_TOKEN=1234567890123456789012345678901234567890123
pip install githubdl
githubdl -u http://github.com/foobar/test -d foo

* Disclaimer: I wrote this package.

If you haven't installed Eclipse yet, I'd recommend Motorola's MotoDev Studio. It does a lot of the annoying little tasks like set up your Android environment along with your paths, and adds a lot of nice built in functionality to Eclipse.

Even if you've already installed Eclipse, you can add it as a plugin (I haven't tried that myself). It is by Motorola, so they have some Motorola centric functionality as well, such as the ability to add your app to the Motorola market. Anyway if you're interested, give it a shot: http://developer.motorola.com/docstools/motodevstudio/

Another solution is just using not to get the opposite negation:

<h2 th:if="${potentially_complex_expression}">Hello!</h2>
<span class="xxx" th:if="${not potentially_complex_expression}">Something else</span>

As explained in the documentation, it's the same thing as using th:unless. As other answers have explained:

Also, th:if has an inverse attribute, th:unless, which we could have used in the previous example instead of using a not inside the OGNL expression

Using not also works, but IMHO it is more readable to use th:unless instead of negating the condition with not.

Use Regular Expressions, if you are going to somehow extend method's functionality.

Html.RenderPartial() is a void method - you can check whether a method is a void method by placing your mouse over the call to RenderPartial in your code and you will see the text (extension) void HtmlHelper.RenderPartial...

Void methods require a semicolon at the end of the calling code.

In the Webforms view engine you would have encased your Html.RenderPartial() call within the bee stings <% %>

like so

<% Html.RenderPartial("Path/to/my/partial/view"); %>

when you are using the Razor view engine the equivalent is

@{Html.RenderPartial("Path/to/my/partial/view");}

I solved it by doing the following:

In Visual studio I went in Project -> Project Dependencies

I selected the XXX.Test solution and told it that it also depends on the XXX solution to make the post-build events in the XXX.Test solution not generate this error (exit with code 4).

Standard is use is or has as a prefix. For example isValid, hasChildren.

Just add float left property on all the divs you want to make appear in a row other than last one. here is example

<div>
  <div style="float: left;">A</div>
  <div style="float: left;">B</div>
  <div>C</div>
</div>

Put webpack -v into your package.json:

{
  "name": "js",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "webpack -v",
    "dev": "webpack --watch"
  }
}

Then enter in the console:

npm run build

Expected output should look like:

> npm run build

> [email protected] build /home/user/repositories/myproject/js
> webpack -v

4.42.0

In Windows 7 and later, this will do the trick for you

• Select the file/files.
• Hold the shift key and then right-click on the selected file/files.
• You will see Copy as Path. Click that.
• Open a Notepad file and paste and you will be good to go.

The menu item Copy as Path is not available in Windows XP.

So I have faced the same problem when trying to start apache service and I would like to share my solutions with you. Here is some notes about services or programs that may use port 80:

1. Skype: skype uses port 80/443 by default. You can change this from tools->options-> advanced->connections and disable checkbox "use port 80 and 443 for addtional incoming connections".
2. IIS: IIS uses port 80 be default so you need to shut down it. You can use the following two commands net stop w3svc net stop iisadmin
3. SQL Server Reporting Service: You need to stop this service because it may take port 80 if IIS is not running. Go to local services and stop it.

These options work great with me and I can start apache service without errors.

The other option is to change apache listen port from httpd.conf and set another port number.

Hope this solution helps anyone who face the same problem again.

i think you use this method to compress the bitmap

BitmapFactory.Option imageOpts = new BitmapFactory.Options ();
imageOpts.inSampleSize = 2;   // for 1/2 the image to be loaded
Bitmap thumb = Bitmap.createScaledBitmap (BitmapFactory.decodeFile(photoPath, imageOpts), 96, 96, false);

<% response.write("<script language=""javascript"">alert('Hello!');</script>") %>

Another gotcha for this kind of problem: avoid running pear within a Unix shell (e.g., Git Bash or Cygwin) on a Windows machine. I had the same problem and the path fix suggested above didn't help. Switched over to a Windows shell, and the pear command works as expected.

1. You could call std::terminate() from any thread and the thread you're referring to will forcefully end.

2. You could arrange for ~thread() to be executed on the object of the target thread, without a intervening join() nor detach() on that object. This will have the same effect as option 1.

3. You could design an exception which has a destructor which throws an exception. And then arrange for the target thread to throw this exception when it is to be forcefully terminated. The tricky part on this one is getting the target thread to throw this exception.

Options 1 and 2 don't leak intra-process resources, but they terminate every thread.

Option 3 will probably leak resources, but is partially cooperative in that the target thread has to agree to throw the exception.

There is no portable way in C++11 (that I'm aware of) to non-cooperatively kill a single thread in a multi-thread program (i.e. without killing all threads). There was no motivation to design such a feature.

A std::thread may have this member function:

native_handle_type native_handle();

You might be able to use this to call an OS-dependent function to do what you want. For example on Apple's OS's, this function exists and native_handle_type is a pthread_t. If you are successful, you are likely to leak resources.

In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.

So register the ChildComponent in Shared Module manually.

Interesting that I didn't see a mention of UTM coordinates.

https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system.

At least if you want to add km to the same zone, it should be straightforward (in Python : https://pypi.org/project/utm/ )

utm.from_latlon and utm.to_latlon.

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

Um... use Markdown's headings!?

That is:

# This is the equivalent of < h1 >

## This is the equivalent of < h4>

### This is the equivalent of < h4>

Many editors will show you a TOC. You can also grep for the heading tags and create your own.

Hope that helps!

You can use a 3rd party library like Shield UI for charting - that is tested and works well on all legacy and new web browsers and devices.

Sometimes it's easier to think in terms of which fields to exclude.

If the number of fields not being cut (not being retained in the output) is small, it may be easier to use the --complement flag, e.g. to include all fields 1-20 except not 3, 7, and 12 -- do this:

cut -d, --complement -f3,7,12 <inputfile

Rather than

cut -d, -f-2,4-6,8-11,13-

As others have said <b> and <i> are explicit (i.e. "make this text bold"), whereas <strong> and <em> are semantic (i.e. "this text should be emphasised").

In the context of a modern web-browser, it's difficult to see the difference (they both appear to produce the same result, right?), but think about screen readers for the visually impaired. If a screen-reader came across an <i> tag, it wouldn't know what to do. But if it comes across a <em> tag, it knows that whatever is within should be emphasised to the listener. And therein you get the practical difference.

Take a look at "SET ROLE" and "SET SESSION AUTHORIZATION".

Yes you can and your DBA will hate you and will find you to nail your shoes to the floor because that will cause lots of I/O and bring the database performance really down as the cache purges.

select column_name from all_tab_columns c, user_all_tables u where c.table_name = u.table_name;

for a start.

I would start with the running queries, using the v$session and the v$sqlarea. This changes based on oracle version. This will narrow down the space and not hit everything.

select pe_name,count( distinct b.ord_id),count(c.item_id) 
 from people  a, order1 as b ,item as c
 where a.pe_id=b.pe_id and
b.ord_id=c.order_id   group by a.pe_id,pe_name

1- There is no way to actually destroy an object in javascript, but using delete, we could remove a reference from an object:

var obj = {};
obj.mypointer = null;
delete obj.mypointer;

2- The important point about the delete keyword is that it does not actually destroy the object BUT if only after deleting that reference to the object, there is no other reference left in the memory pointed to the same object, that object would be marked as collectible. The delete keyword deletes the reference but doesn't GC the actual object. it means if you have several references of the same object, the object will be collected just after you delete all the pointed references.

3- there are also some tricks and workarounds that could help us out, when we want to make sure we do not leave any memory leaks behind. for instance if you have an array consisting several objects, without any other pointed reference to those objects, if you recreate the array all those objects would be killed. For instance if you have var array = [{}, {}] overriding the value of the array like array = [] would remove the references to the two objects inside the array and those two objects would be marked as collectible.

4- for your solution the easiest way is just this:

var storage = {};
storage.instance = new Class();
//since 'storage.instance' is your only reference to the object, whenever you wanted to destroy do this:
storage.instance = null;
// OR
delete storage.instance;

As mentioned above, either setting storage.instance = null or delete storage.instance would suffice to remove the reference to the object and allow it to be cleaned up by the GC. The difference is that if you set it to null then the storage object still has a property called instance (with the value null). If you delete storage.instance then the storage object no longer has a property named instance.

and WHAT ABOUT destroy method ??

the paradoxical point here is if you use instance.destroy in the destroy function you have no access to the actual instance pointer, and it won't let you delete it.

The only way is to pass the reference to the destroy function and then delete it:

// Class constructor
var Class = function () {
     this.destroy = function (baseObject, refName) {
         delete baseObject[refName];
     };
};

// instanciate
var storage = {};
storage.instance = new Class();
storage.instance.destroy(object, "instance");
console.log(storage.instance); // now it is undefined

BUT if I were you I would simply stick to the first solution and delete the object like this:

storage.instance = null;
// OR
delete storage.instance;

WOW it was too much :)
