To answer your question, yes you may pass JSON in the URI as part of a GET request (provided you URL-encode). However, considering your reason for doing this is due to the length of the URI, using JSON will be self-defeating (introducing more characters than required).

I suggest you send your parameters in body of a POST request, either in regular CGI style (param1=val1&param2=val2) or JSON (parsed by your API upon receipt)

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.

There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:

import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text) 
some_elements = soup.find_all("div", class_="myCssClass")

Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.

When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:

from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

ps: take a look at scrapely: https://github.com/scrapy/scrapely

pps: take a look at Portia, to start extracting information visually, without programming knowledge: https://github.com/scrapinghub/portia

Try this way: (for example delete the job)

curl --silent --show-error http://<username>:<api-token>@<jenkins-server>/job/<job-name>/doDelete

The api-token can be obtained from http://<jenkins-server>/user/<username>/configure.

You probably will need to use POST or PATCH, because it is unlikely that a single request that updates and creates multiple resources will be idempotent.

Doing PATCH /docs is definitely a valid option. You might find using the standard patch formats tricky for your particular scenario. Not sure about this.

You could use 200. You could also use 207 - Multi Status

This can be done in a RESTful way. The key, in my opinion, is to have some resource that is designed to accept a set of documents to update/create.

If you use the PATCH method I would think your operation should be atomic. i.e. I wouldn't use the 207 status code and then report successes and failures in the response body. If you use the POST operation then the 207 approach is viable. You will have to design your own response body for communicating which operations succeeded and which failed. I'm not aware of a standardized one.

API(Application Programming Interface), the full form itself suggests that its an Interface which allows you to program for your application with the help or support of some other Application's Interface which exposes some sort of functionality which is useful to your application.

E.g showing updated currency exchange rates on your website would need some third party Interface to program against unless you plan to have your own database with currency rates and regular updates to the same. This set of functionality is when already available with some one else and when they want to share it with others they have to have an endpoint to communicate with the others who are interested in such interactions so they deploy it on web by the means of web-services. This end point is nothing but interface of their application which you can program against hence API.

Markit On Demand provides a set of free financial APIs for playing around with. Looks like there is a stock quote API, a stock ticker/company search and a charting API available. Look at http://dev.markitondemand.com

Another framework which has not been mentioned so far is Laravel. It's great for building PHP apps in general but thanks to the great router it's really comfortable and simple to build rich APIs. It might not be that slim as Slim or Sliex but it gives you a solid structure.

See Aaron Kuzemchak - Simple API Development With Laravel on YouTube and

Laravel 4: A Start at a RESTful API on NetTuts+

Currently, the NASDAQ web site publicly provides CSV files containing bulk listings -- it is broken up by first letter.

http://www.nasdaq.com/screening/companies-by-name.aspx?letter=A&render=download

I solved this by adding .to_json and some heading information

@result = HTTParty.post(@urlstring_to_post.to_str, 
    :body => { :subject => 'This is the screen name', 
               :issue_type => 'Application Problem', 
               :status => 'Open', 
               :priority => 'Normal', 
               :description => 'This is the description for the problem'
             }.to_json,
    :headers => { 'Content-Type' => 'application/json' } )

TL;DR Login for each request is not a required component to implement API security, authentication is.

It is hard to answer your question about login without talking about security in general. With some authentication schemes, there's no traditional login.

REST does not dictate any security rules, but the most common implementation in practice is OAuth with 3-way authentication (as you've mentioned in your question). There is no log-in per se, at least not with each API request. With 3-way auth, you just use tokens.

1. User approves API client and grants permission to make requests in the form of a long-lived token
2. Api client obtains a short-lived token by using the long-lived one.
3. Api client sends the short-lived token with each request.

This scheme gives the user the option to revoke access at any time. Practially all publicly available RESTful APIs I've seen use OAuth to implement this.

I just don't think you should frame your problem (and question) in terms of login, but rather think about securing the API in general.

For further info on authentication of REST APIs in general, you can look at the following resources:

• http://www.infoq.com/news/2010/01/rest-api-authentication-schemes
• REST API Authentication
• RESTful API Authentication

For me, it was getting the nuget package Microsoft.Net.Http .(https://blogs.msdn.microsoft.com/bclteam/p/httpclient/)

barryvdh/laravel-cors works perfectly with Laravel 5.1 with just a few key points in enabling it.

1. After adding it as a composer dependency, make sure you have published the CORS config file and adjusted the CORS headers as you want them. Here is how mine look in app/config/cors.php

   <?php
   
   return [
   
       'supportsCredentials' => true,
       'allowedOrigins' => ['*'],
       'allowedHeaders' => ['*'],
       'allowedMethods' => ['GET', 'POST', 'PUT',  'DELETE'],
       'exposedHeaders' => ['DAV', 'content-length', 'Allow'],
       'maxAge' => 86400,
       'hosts' => [],
   ];
   

2. After this, there is one more step that's not mentioned in the documentation, you have to add the CORS handler 'Barryvdh\Cors\HandleCors' in the App kernel. I prefer to use it in the global middleware stack. Like this

   /**
    * The application's global HTTP middleware stack.
    *
    * @var array
    */
   protected $middleware = [
       'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
       'Illuminate\Cookie\Middleware\EncryptCookies',
       'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
       'Illuminate\Session\Middleware\StartSession',
       'Illuminate\View\Middleware\ShareErrorsFromSession',
   
       'Barryvdh\Cors\HandleCors',
   
   ];
   

   But its up to you to use it as a route middleware and place on specific routes.

This should make the package work with L5.1

I’m tired of looking for free translators and the best option for me was Selenium (more precisely selenide and webdrivermanager) and https://translate.google.com

import io.github.bonigarcia.wdm.ChromeDriverManager;
import com.codeborne.selenide.Configuration;
import io.github.bonigarcia.wdm.DriverManagerType;
import static com.codeborne.selenide.Selenide.*;

public class Main {

    public static void main(String[] args) throws IOException, ParseException {

        ChromeDriverManager.getInstance(DriverManagerType.CHROME).version("76.0.3809.126").setup();
        Configuration.startMaximized = true;
        open("https://translate.google.com/?hl=ru#view=home&op=translate&sl=en&tl=ru");
        String[] strings = /some strings to translate
        for (String data: strings) {
            $x("//textarea[@id='source']").clear();
            $x("//textarea[@id='source']").sendKeys(data);
            String translation = $x("//span[@class='tlid-translation translation']").getText();
        }
    }
}

I've been using the JWT authentication. Works just fine in my application.

There is an authentication method that will require the user credentials. This method validates the credentials and returns an access token in case of success.

This token must be sent to every other method in my Web API in the header of the request.

It's pretty easy to implement, and very easy to test.

First case:

A normal product lookup would look like this

http://our.api.com/product/1

So Im thinking that best practice would be for you to do this

http://our.api.com/Product/101404,7267261

Second Case

Search with querystring parameters - fine like this. I would be tempted to combine terms with AND and OR instead of using [].

PS This can be subjective, so do what you feel comfortable with.

The reason for putting the data in the url is so the link can pasted on a site/ shared between users. If this isnt an issue, by all means use a JSON/ POST instead.

EDIT: On reflection I think this approach suits an entity with a compound key, but not a query for multiple entities.

The terms resource and endpoint are often used synonymously. But in fact they do not mean the same thing.

The term endpoint is focused on the URL that is used to make a request.
The term resource is focused on the data set that is returned by a request.

Now, the same resource can often be accessed by multiple different endpoints.
Also the same endpoint can return different resources, depending on a query string.

Let us see some examples:

Different endpoints accessing the same resource

Have a look at the following examples of different endpoints:

/api/companies/5/employees/3
/api/v2/companies/5/employees/3
/api/employees/3

They obviously could all access the very same resource in a given API.

Also an existing API could be changed completely. This could lead to new endpoints that would access the same old resources using totally new and different URLs:

/api/employees/3
/new_api/staff/3

One endpoint accessing different resources

If your endpoint returns a collection, you could implement searching/filtering/sorting using query strings. As a result the following URLs all use the same endpoint (/api/companies), but they can return different resources (or resource collections, which by definition are resources in themselves):

/api/companies
/api/companies?sort=name_asc
/api/companies?location=germany
/api/companies?search=siemens

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

With your own Code and a Slight Change withou jQuery,

function testingAPI(){ 
    var key = "8a1c6a354c884c658ff29a8636fd7c18"; 
    var url = "https://api.fantasydata.net/nfl/v2/JSON/PlayerSeasonStats/2015";
    console.log(httpGet(url,key)); 
}


function httpGet(url,key){
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", url, false );
    xmlHttp.setRequestHeader("Ocp-Apim-Subscription-Key",key);
    xmlHttp.send(null);
    return xmlHttp.responseText;
}

Thank You

In layman's terms, I've always said an API is like a translator between two people who speak different languages. In software, data can be consumed or distributed using an API (or translator) so that two different kinds of software can communicate. Good software has a strong translator (API) that follows rules and protocols for security and data cleanliness.

I"m a Marketer, not a coder. This all might not be quite right, but it's what I"ve tried to express for about 10 years now...

Look at https://expressjs.com/en/resources/middleware/cors.html You have to use cors.

Install:

$ npm install cors

const cors = require('cors');
app.use(cors());

You have to put this code in your node server.

You can Use this for Curl:

function fakeip()  
{  
    return long2ip( mt_rand(0, 65537) * mt_rand(0, 65535) );   
}  

function getdata($url,$args=false) 
{ 
    global $session; 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL,$url); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("REMOTE_ADDR: ".fakeip(),"X-Client-IP: ".fakeip(),"Client-IP: ".fakeip(),"HTTP_X_FORWARDED_FOR: ".fakeip(),"X-Forwarded-For: ".fakeip())); 
    if($args) 
    { 
        curl_setopt($ch, CURLOPT_POST, 1); 
        curl_setopt($ch, CURLOPT_POSTFIELDS,$args); 
    } 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    //curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1:8888"); 
    $result = curl_exec ($ch); 
    curl_close ($ch); 
    return $result; 
} 

Then To Read Json:

$result=getdata("https://example.com");

Then :

///Deocde Json
$data = json_decode($result,true);
///Count
             $total=count($data);
             $Str='<h1>Total : '.$total.'';
             echo $Str;
//You Can Also Make In Table:
             foreach ($data as $key => $value)
              {
          echo '  <td><font  face="calibri"color="red">'.$value[type].'   </font></td><td><font  face="calibri"color="blue">'.$value[category].'   </font></td><td><font  face="calibri"color="green">'.$value[amount].'   </font></tr><tr>';

           }
           echo "</tr></table>";
           }

You Can Also Use This:

echo '<p>Name : '.$data['result']['name'].'</p>
      <img src="'.$data['result']['pic'].'"><br>';

Hope this helped.

HTML file:

<head>

<meta charset="utf-8">

</head>

PHP file :

<?php header('Content-type: text/plain; charset=utf-8'); ?>

I think the NSURLSession api fits better in this situation. Because if you write swift code your project target is at least iOS 7 and iOS 7 supports NSURLSession api. Anyway here is the code

let url = "YOUR_URL"

NSURLSession.sharedSession().dataTaskWithURL(NSURL(string: url)) { data, response, error in
    // Handle result
}.resume()

There's now also Leaflet, which is built with mobile devices in mind.

There is a Quick Start Guide for leaflet. Besides basic features such as markers, with plugins it also supports routing using an external service.

For a simple map, it is IMHO easier and faster to set up than OpenLayers, yet fully configurable and tweakable for more complex uses.

We had the same problem when making our API as well. We were looking for an HTTP status code equivalent to an InvalidArgumentException. After reading the source article below, we ended up using 422 Unprocessable Entity which states:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.

REST

It is neither an API nor a framework. It is just an architectural concept. You can find more details here.

RESTful

I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.

EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.

Web API

It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).

Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.

Self-contained example

Same technique as in this answer but:

• self-contained: copy paste and it will compile and run
• with a button for you to generated as many notifications as you like and play with intent and notification IDs

                Main.this.i++;
            }

        this.setContentView(button);

Using Firebase Console you can send message to all users based on application package.But with CURL or PHP API its not possible.

Through API You can send notification to specific device ID or subscribed users to selected topic or subscribed topic users.

My work uses Winnovative's PDF generator (We've used it mainly to convert HTML to PDF, but you can generate it other ways as well)

Issue Log: App Not Setup. This app is still in development mode. and you dont have access to it. register test user or ask an app admin for permission

1. The app are not in Live Mode
2. You are not listed as admin or a tester in
   https://developers.facebook.com/app/yourapp
3. Your App Hashkey are not set. if Facebook app cant be on Live Mode you need a hashkey to test it. because the app are not yet Live. Facebook wont allow an access.

HOW TO CHANGE TO LIVE MODE
1. go to : https://developers.facebook.com
2. select your app on "My Apps" List
3. toggle the switch from OFF to ON

HOW TO ADD AS TEST OR ADMIN
1. go to : https://developers.facebook.com
2. select your app on "My Apps" List
3. go to : Roles > Roles > Press Add for example administrator 4. Search your new admin/tester Facebook account.
5. admin must enter facebook password to confirm.then submit
the new admin must go to developer.facebook page and accept the request
6. go to : https://developers.facebook.com

7. Profile > Requests > Confirm
8. Congratulation you have been assign as new Admin

HOW TO GET AND SET HASHKEY FOR DEVELOPMENT
as Refer to Facebook Login Documentation
https://developers.facebook.com/docs/android/getting-started/#create_hash
The most preferable solution by me is by code ( Troubleshooting Sample Apps )
it will print out the hash key. you can update it on
https://developers.facebook.com/apps/yourFacebookappID/settings/basic/
on Android > Key Hashes section

a step by step process on how to get the hashKey.

1. Firstly Add the code to any oncreate method

2. Run The app and Search the KeyHash at Logcat

step by step process on how Update on Facebook Developer.

3. Open Facebook Developer Page. You need access as to update the Facebook Developer page.
   https://developers.facebook.com

4. Follow the step as follow.

this code will work to sign out

    <script>
      function signOut() 
      {
        var auth2 = gapi.auth2.getAuthInstance();
        auth2.signOut().then(function () {   
        console.log('User signed out.');   
        auth2.disconnect();   
      }); 
        auth2.disconnect();
      } 
    </script>

If the Exception is being thrown in that try block then at worst case scenario Exception should be catching anything uncaught.

Consider that the first part of the test is throwing the Exception and wrap that in the try block as well.

I would say that it's preferable to use as few special characters as possible in REST URLs. One of the benefits of REST is that it makes the "interface" for a service easy to read. Camel case or Pascal case is probably good for the resource names (Users or users). I don't think there are really any hard standards around REST.

Also, I think Gandalf is right, it's usually cleaner in REST to not use query string parameters, but instead create paths that define which resources you want to deal with.

http://api.example.com/HelloWorld/Users/12345/Order/3/etc

TimezoneDb provides a free API: http://timezonedb.com/api

GenoNames also has a RESTful API available to get the current time for a given location: http://www.geonames.org/export/ws-overview.html.

You can use Greenwich, UK if you'd like GMT.

no need to use user and password as part of the URL

you can try this

byte[] encodedBytes = Base64.encodeBase64("user:passwd".getBytes());

String USER_PASS = new String(encodedBytes);

HttpUriRequest request = RequestBuilder.get(url).addHeader("Authorization", USER_PASS).build();

Trying to write a REST API from scratch is not a simple task. There are many issues to factor and you will need to write a lot of code to process requests and data coming from the caller, authentication, retrieval of data and sending back responses.

Your best bet is to use a framework that already has this functionality ready and tested for you.

and many more. Simple searches on Bitbucket/Github will give you a lot of resources to start with.

You could also get the error if your Billing is not set up correctly.

Google hands out credit worth $300 or 12 months of free usage whichever runs out faster. After that you would need to enable billing.

Ultimately no. You can query for listings with a search string from an RSS feed such as this:

http://YOURCITY.craigslist.org/search/sss?format=rss&query=SearchString

As far as posting, craiglist has not opened their API. However, this SO Question may shed some light and a possible solution - although not a very reliable one.

Craigslist Automated Posting API?

Write a note to craigslist asking them to open their API,

I haven't tested on other Laravel versions but on 5.3-5.8 you reference the query parameter as if it were a member of the Request class.

1. Url

http://example.com/path?page=2

2. In a route callback or controller action using magic method Request::__get()

Route::get('/path', function(Request $request){
 dd($request->page);
}); 

//or in your controller
public function foo(Request $request){
 dd($request->page);
}

//NOTE: If you are wondering where the request instance is coming from, Laravel automatically injects the request instance from the IOC container
//output
"2"

3. Default values

We can also pass in a default value which is returned if a parameter doesn't exist. It's much cleaner than a ternary expression that you'd normally use with the request globals

   //wrong way to do it in Laravel
   $page = isset($_POST['page']) ? $_POST['page'] : 1; 

   //do this instead
   $request->get('page', 1);

   //returns page 1 if there is no page
   //NOTE: This behaves like $_REQUEST array. It looks in both the
   //request body and the query string
   $request->input('page', 1);

4. Using request function

$page = request('page', 1);
//returns page 1 if there is no page parameter in the query  string
//it is the equivalent of
$page = 1; 
if(!empty($_GET['page'])
   $page = $_GET['page'];

The default parameter is optional therefore one can omit it

5. Using Request::query()

While the input method retrieves values from entire request payload (including the query string), the query method will only retrieve values from the query string

//this is the equivalent of retrieving the parameter
//from the $_GET global array
$page = $request->query('page');

//with a default
$page = $request->query('page', 1);

6. Using the Request facade

$page = Request::get('page');

//with a default value
$page = Request::get('page', 1);

I was struggling for hours on this until I figured out it can be done in one line of powershell:

invoke-webrequest -Uri "http://myserver/Reports/Pages/ReportViewer.aspx?%2fClients%2ftest&rs:Format=PDF&rs:ClearSession=true&CaseCode=12345678" -OutFile "C:\Temp\test.pdf" -UseDefaultCredentials

I looked into doing it purely in VBA but it runs to several pages, so I just call my powershell script from VBA every time I want to download a file.

Simple.

If you need something quick and dirty, you can just use PayPal's "Buy" buttons and drop them on your pages. These will take people off-site to PayPal where they can pay with a PayPal account or a credit card. This is free and super easy to implement.

If you want something a bit nicer where people pay on-site with their credit card, then you would want to look into one of those 3rd part payment providers. None of them (that I'm aware of) are completely free. All will have a per-transaction fee, and most will have a monthly fee as well.

Personally I've worked with Authorize.NET and PayPal Website Payments Pro. Both have great APIs and sample code that you can hook into via PHP easily enough.

This is what worked for me... I did not use curl.

I was able to access a particular API url via browser, but when used in file_get_contents, it gave the error " failed to open stream".

Then, I modified the API URL that I wanted to call by encoding all double quotes with urlencoding and kept everything else untouched.

Sample format is given below:

$url = 'https://stackoverflow.com/questions'.urlencode('"'.$variable1.'"');

Then use

file_get_contents($url);

Actually you don't have to deal with the static metamodel if you had your annotations right.

With the following entities :

@Entity
public class Pet {
  @Id
  protected Long id;
  protected String name;
  protected String color;
  @ManyToOne
  protected Set<Owner> owners;
}

@Entity
public class Owner {
  @Id
  protected Long id;
  protected String name;
}

You can use this :

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> petMetaModel = m.entity(Pet.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Pet, Owner> owner = pet.join(petMetaModel.getSet("owners", Owner.class));

If you are passing all your parameters on the URL, then probably comma separated values would be the best choice. Then you would have an URL template like the following:

api.com/users?id=id1,id2,id3,id4,id5

API keys are just one way of authenticating users of web services.

Create a C# class that maps to your Json and use Newsoft JsonConvert to Deserialise it.

For example:

public Class MyResponse
{
    public Meta Meta { get; set; }
    public Response Response { get; set; }
}

I have used TestNG and Apache HTTP classes to build my own REST API test framework, I developed this concept after working in Selenium for two years.

Everything is same, except you should use Apache HTTP classes instead of Selenium classes.

give a try, its really cute and good, you've all the power to customize your test framework to your fullest possibilities.

Yahoo has a YQL feature to get a whole bunch of currencies at once in XML or JSON. I've noticed the data is up to date by the minute where the ECB has day old data, and stops in the weekend.

http://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("USDEUR", "USDJPY", "USDBGN", "USDCZK", "USDDKK", "USDGBP", "USDHUF", "USDLTL", "USDLVL", "USDPLN", "USDRON", "USDSEK", "USDCHF", "USDNOK", "USDHRK", "USDRUB", "USDTRY", "USDAUD", "USDBRL", "USDCAD", "USDCNY", "USDHKD", "USDIDR", "USDILS", "USDINR", "USDKRW", "USDMXN", "USDMYR", "USDNZD", "USDPHP", "USDSGD", "USDTHB", "USDZAR", "USDISK")&env=store://datatables.org/alltableswithkeys

Here is their query builder, where you can test a query and copy the url:

http://developer.yahoo.com/yql/console/?q=show%20tables&env=store://datatables.org/alltableswithkeys#h=select%20*%20from%20yahoo.finance.xchange%20where%20pair%20in%20%28%22USDMXN%22%2C%20%22USDCHF%22%29

This actually sums it up pretty nicely.

API Levels generally mean that as a programmer, you can communicate with the devices' built in functions and functionality. As the API level increases, functionality adds up (although some of it can get deprecated).

Choosing an API level for an application development should take at least two thing into account:

1. Current distribution - How many devices can actually support my application, if it was developed for API level 9, it cannot run on API level 8 and below, then "only" around 60% of devices can run it (true to the date this post was made).
2. Choosing a lower API level may support more devices but gain less functionality for your app. you may also work harder to achieve features you could've easily gained if you chose higher API level.

Android API levels can be divided to five main groups (not scientific, but what the heck):

1. Android 1.5 - 2.3 (Cupcake to Gingerbread) - (API levels 3-10) - Android made specifically for smartphones.
2. Android 3.0 - 3.2 (Honeycomb) (API levels 11-13) - Android made for tablets.
3. Android 4.0 - 4.4 (KitKat) - (API levels 14-19) - A big merge with tons of additional functionality, totally revamped Android version, for both phone and tablets.
4. Android 5.0 - 5.1 (Lollipop) - (API levels 21-22) - Material Design introduced.
5. Android 6.0 - 6.… (Marshmallow) - (API levels 23-…) - Runtime Permissions,Apache HTTP Client Removed

You can fetch the list of tables and schemata by querying the SQLITE_MASTER table:

sqlite> .tab
job         snmptarget  t1          t2          t3        
sqlite> select name from sqlite_master where type = 'table';
job
t1
t2
snmptarget
t3

sqlite> .schema job
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
);
sqlite> select sql from sqlite_master where type = 'table' and name = 'job';
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
)

My approach was as follows (in PHP):

$url = "whatever_you_need"

$html = file_get_contents('https://en.wikipedia.org/w/api.php?action=opensearch&search='.$url);
$utf8html = html_entity_decode(preg_replace("/U\+([0-9A-F]{4})/", "&#x\\1;", $html), ENT_NOQUOTES, 'UTF-8');

$utf8html might need further cleaning, but that's basically it.

At least for the Windows binary version I tested, (the Generic Win64 no-SSL binary, currently based on 7.33.0), you are subject to limitations in how the command line arguments are being parsed. The answer by xmas describes the correct syntax in that setting, which also works in a batch file. Using the example provided:

curl -i -X POST -H "Content-Type: application/json" -d "{""data1"":""data goes here"",""data2"":""data2 goes here""}" http:localhost/path/to/api

A cleaner alternative to avoid having to deal with escaped characters, which is dependent upon whatever library is used to parse the command line, is to have your standard json format text in a separate file:

curl -i -X POST -H "Content-Type: application/json" -d "@body.json" http:localhost/path/to/api

1. As per Google's documentation, you should use Google's AP Client Library that makes this (token verification, claim extraction etc.) much easier than writing your own custom code.

2. From a performance perspective, the token should be parsed locally without making a call to Google again. Off-course Google's public key is needed and retrieval of that key is done using a caching strategy, implemented in the Google's client library from #1 above.

3. FYI only. Google also uses a JWT token. See image below for reference.

Your problem is caused by the lack of markers OpenGraph, as you say it is not possible that you implement for some reason.

For you, the only solution is to use the PHP Facebook API.

1. First you must create the application in your facebook account.

2. When creating the application you will have two key data for your code:

   YOUR_APP_ID 
   YOUR_APP_SECRET
   

3. Download the Facebook PHP SDK from here.

4. You can start with this code for share content from your site:

   <?php
     // Remember to copy files from the SDK's src/ directory to a
     // directory in your application on the server, such as php-sdk/
     require_once('php-sdk/facebook.php');
   
     $config = array(
       'appId' => 'YOUR_APP_ID',
       'secret' => 'YOUR_APP_SECRET',
       'allowSignedRequest' => false // optional but should be set to false for non-canvas apps
     );
   
     $facebook = new Facebook($config);
     $user_id = $facebook->getUser();
   ?>
   <html>
     <head></head>
     <body>
   
     <?php
       if($user_id) {
   
         // We have a user ID, so probably a logged in user.
         // If not, we'll get an exception, which we handle below.
         try {
           $ret_obj = $facebook->api('/me/feed', 'POST',
                                       array(
                                         'link' => 'www.example.com',
                                         'message' => 'Posting with the PHP SDK!'
                                    ));
           echo '<pre>Post ID: ' . $ret_obj['id'] . '</pre>';
   
           // Give the user a logout link 
           echo '<br /><a href="' . $facebook->getLogoutUrl() . '">logout</a>';
         } catch(FacebookApiException $e) {
           // If the user is logged out, you can have a 
           // user ID even though the access token is invalid.
           // In this case, we'll get an exception, so we'll
           // just ask the user to login again here.
           $login_url = $facebook->getLoginUrl( array(
                          'scope' => 'publish_stream'
                          )); 
           echo 'Please <a href="' . $login_url . '">login.</a>';
           error_log($e->getType());
           error_log($e->getMessage());
         }   
       } else {
   
         // No user, so print a link for the user to login
         // To post to a user's wall, we need publish_stream permission
         // We'll use the current URL as the redirect_uri, so we don't
         // need to specify it here.
         $login_url = $facebook->getLoginUrl( array( 'scope' => 'publish_stream' ) );
         echo 'Please <a href="' . $login_url . '">login.</a>';
   
       } 
   
     ?>      
   
     </body> 
   </html>

I don't think so. The API's will provide access to delayed quotes, there is no way that real time data or tick data, will be provided for free.

As per: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

9.2 OPTIONS

The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the Request-URI. This method allows the client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without implying a resource action or initiating a resource retrieval.

Responses to this method are not cacheable.

If the OPTIONS request includes an entity-body (as indicated by the presence of Content-Length or Transfer-Encoding), then the media type MUST be indicated by a Content-Type field. Although this specification does not define any use for such a body, future extensions to HTTP might use the OPTIONS body to make more detailed queries on the server. A server that does not support such an extension MAY discard the request body.

If the Request-URI is an asterisk ("*"), the OPTIONS request is intended to apply to the server in general rather than to a specific resource. Since a server's communication options typically depend on the resource, the "*" request is only useful as a "ping" or "no-op" type of method; it does nothing beyond allowing the client to test the capabilities of the server. For example, this can be used to test a proxy for HTTP/1.1 compliance (or lack thereof).

If the Request-URI is not an asterisk, the OPTIONS request applies only to the options that are available when communicating with that resource.

A 200 response SHOULD include any header fields that indicate optional features implemented by the server and applicable to that resource (e.g., Allow), possibly including extensions not defined by this specification. The response body, if any, SHOULD also include information about the communication options. The format for such a body is not defined by this specification, but might be defined by future extensions to HTTP. Content negotiation MAY be used to select the appropriate response format. If no response body is included, the response MUST include a Content-Length field with a field-value of "0".

The Max-Forwards request-header field MAY be used to target a specific proxy in the request chain. When a proxy receives an OPTIONS request on an absoluteURI for which request forwarding is permitted, the proxy MUST check for a Max-Forwards field. If the Max-Forwards field-value is zero ("0"), the proxy MUST NOT forward the message; instead, the proxy SHOULD respond with its own communication options. If the Max-Forwards field-value is an integer greater than zero, the proxy MUST decrement the field-value when it forwards the request. If no Max-Forwards field is present in the request, then the forwarded request MUST NOT include a Max-Forwards field.

9.4 HEAD

The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response. The metainformation contained in the HTTP headers in response to a HEAD request SHOULD be identical to the information sent in response to a GET request. This method can be used for obtaining metainformation about the entity implied by the request without transferring the entity-body itself. This method is often used for testing hypertext links for validity, accessibility, and recent modification.

The response to a HEAD request MAY be cacheable in the sense that the information contained in the response MAY be used to update a previously cached entity from that resource. If the new field values indicate that the cached entity differs from the current entity (as would be indicated by a change in Content-Length, Content-MD5, ETag or Last-Modified), then the cache MUST treat the cache entry as stale.

10 Open Source Android Apps which every Android developer must look into

Foursquared for Android is open-source, and have an interesting code pattern interacting with the foursquare REST API.

An IDE is an integrated development environment - a suped-up text editor with additional support for developing (such as forms designers, resource editors, etc), compiling and debugging applications. e.g Eclipse, Visual Studio.

A Library is a chunk of code that you can call from your own code, to help you do things more quickly/easily. For example, a Bitmap Processing library will provide facilities for loading and manipulating bitmap images, saving you having to write all that code for yourself. Typically a library will only offer one area of functionality (processing images or operating on zip files)

An API (application programming interface) is a term meaning the functions/methods in a library that you can call to ask it to do things for you - the interface to the library.

An SDK (software development kit) is a library or group of libraries (often with extra tool applications, data files and sample code) that aid you in developing code that uses a particular system (e.g. extension code for using features of an operating system (Windows SDK), drawing 3D graphics via a particular system (DirectX SDK), writing add-ins to extend other applications (Office SDK), or writing code to make a device like an Arduino or a mobile phone do what you want). An SDK will still usually have a single focus.

A toolkit is like an SDK - it's a group of tools (and often code libraries) that you can use to make it easier to access a device or system... Though perhaps with more focus on providing tools and applications than on just code libraries.

A framework is a big library or group of libraries that provides many services (rather than perhaps only one focussed ability as most libraries/SDKs do). For example, .NET provides an application framework - it makes it easier to use most (if not all) of the disparate services you need (e.g. Windows, graphics, printing, communications, etc) to write a vast range of applications - so one "library" provides support for pretty much everything you need to do. Often a framework supplies a complete base on which you build your own code, rather than you building an application that consumes library code to do parts of its work.

There are of course many examples in the wild that won't exactly match these descriptions though.

After a certain amount of time, your access token expires.

To prevent this, you can request the 'offline_access' permission during the authentication, as noted here: Do Facebook Oauth 2.0 Access Tokens Expire?

Wikipedia is built on MediaWiki, and here's the MediaWiki API.

I have different approach if you want access token and make call to other resource system with access token in header

Spring Security comes with automatic security: oauth2 properties access from application.yml file for every request and every request has SESSIONID which it reads and pull user info via Principal, so you need to make sure inject Principal in OAuthUser and get accessToken and make call to resource server

This is your application.yml, change according to your auth server:

security:
  oauth2:
    client:
      clientId: 233668646673605
      clientSecret: 33b17e044ee6a4fa383f46ec6e28ea1d
      accessTokenUri: https://graph.facebook.com/oauth/access_token
      userAuthorizationUri: https://www.facebook.com/dialog/oauth

      authenticationScheme: query

When I printed response.read() I noticed that b was preprended to the string (e.g. b'{"a":1,..). The "b" stands for bytes and serves as a declaration for the type of the object you're handling. Since, I knew that a string could be converted to a dict by using json.loads('string'), I just had to convert the byte type to a string type. I did this by decoding the response to utf-8 decode('utf-8'). Once it was in a string type my problem was solved and I was easily able to iterate over the dict.

I don't know if this is the fastest or most 'pythonic' way of writing this but it works and theres always time later of optimization and improvement! Full code for my solution:

from urllib.request import urlopen
import json

# Get the dataset
url = 'http://www.quandl.com/api/v1/datasets/FRED/GDP.json'
response = urlopen(url)

# Convert bytes to string type and string type to dict
string = response.read().decode('utf-8')
json_obj = json.loads(string)

print(json_obj['source_name']) # prints the string with 'source_name' key

Modern Spring 5+ answer using WebClient instead of RestTemplate.

Configure WebClient for a specific web-service or resource as a bean (additional properties can be configured).

@Bean
public WebClient localApiClient() {
    return WebClient.create("http://localhost:8080/api/v3");
}

Inject and use the bean from your service(s).

@Service
public class UserService {

    private static final Duration REQUEST_TIMEOUT = Duration.ofSeconds(3);

    private final WebClient localApiClient;

    @Autowired
    public UserService(WebClient localApiClient) {
        this.localApiClient = localApiClient;
    }

    public User getUser(long id) {
        return localApiClient
                .get()
                .uri("/users/" + id)
                .retrieve()
                .bodyToMono(User.class)
                .block(REQUEST_TIMEOUT);
    }

}

For some of my technical experiments, I was trying to figure out how beneficial and feasible it is to implement bots for different chat platforms in terms of market share and so possibilities of adaptation. Especially when you have bankruptly failed twice, it's important to validate ideas and fail more faster.

Popular chat platforms like Messenger, Slack, Skype etc. have happily (in the sense officially) provided APIs for bots to interact with, but WhatsApp has not yet provided any API.

However, since many years, a lot of activities has happened around this - struggle towards automated interaction with WhatsApp platform:

1. Bots App Bots App is interesting because it shows that something is really tried and tested.

2. Yowsup A project still actively developed to interact with WhatsApp platform.

3. Yallagenie Yallagenie claim that there is a demo bot which can be interacted with at +971 56 112 6652

4. Hubtype Hubtype is working towards having a bot platform for WhatsApp for business.

5. Fred Fred's task was to automate WhatsApp conversations, however since it was not officially supported by WhatsApp - it was shut down.

6. Oye Gennie A bot blocked by WhatsApp.

7. App/Website to WhatsApp We can use custom URL schemes and Android intent system to interact with WhatsApp but still NOT WhatsApp API.

8. Chat API daemon Probably created by inspecting the API calls in WhatsApp web version. NOT affiliated with WhatsApp.

9. WhatsBot Deactivated WhatsApp bot. Created during a hackathon.

10. No API claim WhatsApp co-founder clearly stated this in a conference that they did not had any plans for APIs for WhatsApp.

11. Bot Ware They probably are expecting WhatsApp to release their APIs for chat bot platforms.

12. Vixi They seems to be talking about how some platform which probably would work for WhatsApp. There is no clarity as such.

13. Unofficial API This API can shut off any time.

    And the number goes on...

An endpoint is a URL pattern used to communicate with an API.

Only related with currency trading (Forex), but many Forex brokers are offering MetaTrader which let you code in MQL. The main problem with it (aside that it's limited to Forex) is that you've to code in MQL which might not be your preferred language.

It's a mechanism to invoke an API in an asynchrounous way. The sequence is the following

1. your app invokes the url, passing as parameter the callback url
2. the api respond with a 20x http code (201 I guess, but refer to the api docs)
3. the api works on your request for a certain amount of time
4. the api invokes your app to give you the results, at the callback url address.

So you can invoke the api and tell your user the request is "processing" or "acquired" for example, and then update the status when you receive the response from the api.

Hope it makes sense. -G

Application Programming Interface is a set of routines/data structures/classes which specifies a way to interact with the target platform/software like OS X, Android, project management application, virtualization software etc.

While Software Development Kit is a wrapper around API/s that makes the job easy for developers.

For example, Android SDK facilitates developers to interact with the Android platform as a whole while the platform itself is built by composite software components communicating via APIs.

Also, sometimes SDKs are built to facilitate development in a specific programming language. For example, Selenium web driver (built in Java) provides APIs to drive any browser natively, while capybara can be considered an an SDK that facilitates Ruby developers to use Selenium web driver. However, Selenium web driver is also an SDK by itself as it combines interaction with various native browser drivers into one package.

Try Tixik.com and their API there. They have a very different data that big players, really good coverage mostly in Europe and good API conditions.

You're right, the Instagram API will only return 20 images per call. So you'll have to use the pagination feature.

If you're trying to use the API console. You'll want to first allow the API console to authenticate via your Instagram login. To do this you'll want to select OAUTH2 under the Authentication dropdown.

Once Authenticated, use the left hand side menu to select the users/{user-id}/media/recent endpoint. So for the sake of this post for {user-id} you can just replace it with self. This will then use your account to retrieve information.

At a bare minimum that is what's needed to do a GET for this endpoint. Once you send, you'll get some json returned to you. At the very top of the returned information after all the server info, you'll see a pagination portion with next_url and next_max_id.

next_max_id is what you'll use as a parameter for your query. Remember max_id is the id of the image that is the oldest of the 20 that was first returned. This will be used to return images earlier than this image.

You don't have to use the max_id if you don't want to. You can actually just grab the id of the image where you'd like to start querying more images from.

So from the returned data, copy the max_id into the parameter max_id. The request URL should look something like this https://api.instagram.com/v1/users/self/media/recent?max_id=XXXXXXXXXXX where XXXXXXXXXXX is the max_id. Hit send again and you should get the next 20 photos.

From there you'll also receive an updated max_id. You can then use that again to get the next set of 20 photos until eventually going through all of the user's photos.

What I've done in the project I'm working on is to load the first 20 photos returned from the initial recent media request. I then, assign the images with a data-id (-id can actually be whatever you'd like it to be). Then added a load more button on the bottom of the photo set.

When the button is clicked, I use jQuery to grab the last image and it's data-id attribute and use that to create a get call via ajax and append the results to the end of the photos already on the page. Instead of a button you could just replace it to have a infinite scrolling effect.

Hope that helps.

The only way to see more is to start saving them before the user's tweet count hits 3200. Services which show more than 3200 tweets have saved them in their own dbs. There's currently no way to get more than that through any Twitter API.

http://www.quora.com/Is-there-a-way-to-get-more-than-3200-tweets-from-a-twitter-user-using-Twitters-API-or-scraping

https://dev.twitter.com/discussions/276

Note from that second link: "…the 3,200 limit is for browsing the timeline only. Tweets can always be requested by their ID using the GET statuses/show/:id method."

In REST, each HTTP verbs has its place and meaning.

For example,

• GET is to get the 'resource(s)' that is pointed to in the URL.

• POST is to instructure the backend to 'create' a resource of the 'type' pointed to in the URL. You can supplement the POST operation with parameters or additional data in the body of the POST call.

In you case, since you are interested in 'getting' the info using query, thus it should be a GET operation instead of a POST operation.

This wiki may help to further clarify things.

Hope this help!

In regards to using extension to define data type. I noticed that MailChimp API is doing it, but I don't think this is a good idea.

GET /zzz/cars.json/1

GET /zzz/cars.xml/1

My sound like a good idea, but I think "older" approach is better - using HTTP headers

GET /xxx/cars/1
Accept: application/json

Also HTTP headers are much better for cross data type communication (if ever someone would need it)

POST /zzz/cars
Content-Type: application/xml     <--- indicates we sent XML to server
Accept: application/json          <--- indicates we want get data back in JSON format  

i use firebase-database in html signup but last error i cannot understand if anybody know tell me . error is "Failed to load resource: the server responded with a status of 404 ()"

What you may want to do is include a script on all pages that does the following ... 1. find the youtube-iframe : searching for it by width and height by title or by finding www.youtube.com in its source. You can do that by ... - looping through the window.frames by a for-in loop and then filter out by the properties

1. inject jscript in the iframe of the current page adding the onYoutubePlayerReady must-include-function http://shazwazza.com/post/Injecting-JavaScript-into-other-frames.aspx

2. Add the event listeners etc..

Hope this helps

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

I got the same error, but when i did as below, it resolved the issue.
Instead of writing like this:

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

use the below one:

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

I've tried a some of the solutions in this thread, and unfortunately, I found some of them to be cumbersome (i.e. requiring excessive effort when doing something non-trivial) and inelegant. Consequently, I thought I'd throw my preferred solution, web2py HTML helper objects, into the mix.

First, install the the standalone web2py module:

pip install web2py

Unfortunately, the above installs an extremely antiquated version of web2py, but it'll be good enough for this example. The updated source is here.

Import web2py HTML helper objects documented here.

from gluon.html import *

Now, you can use web2py helpers to generate XML/HTML.

words = ['this', 'is', 'my', 'item', 'list']
# helper function
create_item = lambda idx, word: LI(word, _id = 'item_%s' % idx, _class = 'item')
# create the HTML
items = [create_item(idx, word) for idx,word in enumerate(words)]
ul = UL(items, _id = 'my_item_list', _class = 'item_list')
my_div = DIV(ul, _class = 'container')

>>> my_div

<gluon.html.DIV object at 0x00000000039DEAC8>

>>> my_div.xml()
# I added the line breaks for clarity
<div class="container">
   <ul class="item_list" id="my_item_list">
      <li class="item" id="item_0">this</li>
      <li class="item" id="item_1">is</li>
      <li class="item" id="item_2">my</li>
      <li class="item" id="item_3">item</li>
      <li class="item" id="item_4">list</li>
   </ul>
</div>

Generally speaking, 5xx response codes indicate non-programmatic failures, such as a database connection failure, or some other system/library dependency failure. In many cases, it is expected that the client can re-submit the same request in the future and expect it to be successful.

Yes, some web-frameworks will respond with 5xx codes, but those are typically the result of defects in the code and the framework is too abstract to know what happened, so it defaults to this type of response; that example, however, doesn't mean that we should be in the habit of returning 5xx codes as the result of programmatic behavior that is unrelated to out of process systems. There are many, well defined response codes that are more suitable than the 5xx codes. Being unable to parse/validate a given input is not a 5xx response because the code can accommodate a more suitable response that won't leave the client thinking that they can resubmit the same request, when in fact, they can not.

To be clear, if the error encountered by the server was due to CLIENT input, then this is clearly a CLIENT error and should be handled with a 4xx response code. The expectation is that the client will correct the error in their request and resubmit.

It is completely acceptable, however, to catch any out of process errors and interpret them as a 5xx response, but be aware that you should also include further information in the response to indicate exactly what failed; and even better if you can include SLA times to address.

I don't think it's a good practice to interpret, "an unexpected error" as a 5xx error because bugs happen.

It is a common alert monitor to begin alerting on 5xx types of errors because these typically indicate failed systems, rather than failed code. So, code accordingly!

I use http://hurl.it/

Ha. Sorry, I mis-read your post. I've used cucumber to test it before. It worked out nicely.

Never use AsynTask to perform network request or whatever that need to be persisted. Async Task are strongly tied to your activity and if the user change the orientation of the screen since the App is re created the AsyncTask will be stopped.

I suggest you to use Service pattern with Intent Service and ResultReceiver. Take a look to RESTDroid. It's a library that allows you to perform any kind of REST request asynchronously and notify your UI with Request Listeners implementing the Virgil Dobjanschi's service pattern.

gmap.animateCamera(CameraUpdateFactory.newCameraPosition(new CameraPosition(new LatLng(9.491327, 76.571404), 10, 30, 0)));

You can add a header parameter to your request, and Swagger-UI will show it as an editable text box:

swagger: "2.0"
info:
  version: 1.0.0
  title: TaxBlaster
host: taxblaster.com
basePath: /api
schemes:
- http

paths:

  /taxFilings/{id}:

    get:
      parameters:
      - name: id
        in: path
        description: ID of the requested TaxFiling
        required: true
        type: string
      - name: auth
        in: header
        description: an authorization header

        type: string
      responses:

          description: Successful response, with a representation of the Tax Filing.
          schema:
            $ref: "#/definitions/TaxFilingObject"
        404:
          description: The requested tax filing was not found.

definitions:
  TaxFilingObject:
    type: object
    description: An individual Tax Filing record.
    properties:

        type: string
      period:
        type: integer
      currency:
        type: string
      taxpayer:
        type: object

You can also add a security definition with type apiKey:

swagger: "2.0"
info:
  version: 1.0.0
  title: TaxBlaster
host: taxblaster.com
basePath: /api
schemes:
- http

securityDefinitions:
  api_key:
    type: apiKey
    name: api_key
    in: header
    description: Requests should pass an api_key header.

security: 
 - api_key: []

paths:

  /taxFilings/{id}:

    get:
      parameters:
      - name: id
        in: path
        description: ID of the requested TaxFiling
        required: true
        type: string

      responses:
        200:
          description: Successful response, with a representation of the Tax Filing.
          schema:
            $ref: "#/definitions/TaxFilingObject"
        404:
          description: The requested tax filing was not found.

definitions:
  TaxFilingObject:
    type: object
    description: An individual Tax Filing record.
    properties:
      filingID:
        type: string
      year:
        type: string
      period:
        type: integer
      currency:
        type: string
      taxpayer:
        type: object

The securityDefinitions object defines security schemes.

The security object (called "security requirements" in Swagger–OpenAPI), applies a security scheme to a given context. In our case, we're applying it to the entire API by declaring the security requirement a top level. We can optionally override it within individual path items and/or methods.

This would be the preferred way to specify your security scheme; and it replaces the header parameter from the first example. Unfortunately, Swagger-UI doesn't offer a text box to control this parameter, at least in my testing so far.

If there are documented best practices, I have not found them yet. However, here are a few guidelines I use when determining where to put parameters in an url:

Optional parameters tend to be easier to put in the query string.

If you want to return a 404 error when the parameter value does not correspond to an existing resource then I would tend towards a path segment parameter. e.g. /customer/232 where 232 is not a valid customer id.

If however you want to return an empty list then when the parameter is not found then I suggest using query string parameters. e.g. /contacts?name=dave

If a parameter affects an entire subtree of your URI space then use a path segment. e.g. a language parameter /en/document/foo.txt versus /document/foo.txt?language=en

I prefer unique identifiers to be in a path segment rather than a query parameter.

The official rules for URIs are found in this RFC spec here. There is also another very useful RFC spec here that defines rules for parameterizing URIs.

It is not possible yet to search for content using multiple tags, for now only single tags are supported.

Firstly, the Instagram API endpoint "tags" required OAuth authentication.

This is not quite true, you only need an API-Key. Just register an application and add it to your requests. Example:

https://api.instagram.com/v1/users/userIdYouWantToGetMediaFrom/media/recent?client_id=yourAPIKey

Also note that the username is not the user-id. You can look up user-Id`s here.

A workaround for searching multiple keywords would be if you start one request for each tag and compare the results on your server. Of course this could slow down your site depending on how much keywords you want to compare.

This might help someone who use Zend_Oauth_Client to work with twitter api. This working config:

$accessToken = new Zend_Oauth_Token_Access();
$accessToken->setToken('accessToken');
$accessToken->setTokenSecret('accessTokenSecret');

$client = $accessToken->getHttpClient(array(
    'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER,
    'version' => '1.0', // it was 1.1 and I got 215 error.
    'signatureMethod' => 'HMAC-SHA1',
    'consumerKey' => 'foo',
    'consumerSecret' => 'bar',
    'requestTokenUrl' => 'https://api.twitter.com/oauth/request_token',
    'authorizeUrl' => 'https://api.twitter.com/oauth/authorize',
    'accessTokenUrl' => 'https://api.twitter.com/oauth/access_token',
    'timeout' => 30
));

It look like twitter api 1.0 allows oauth version to be 1.1 and 1.0, where twitter api 1.1 require only oauth version to be 1.0.

P.S We do not use Zend_Service_Twitter as it does not allow send custom params on status update.

If you need Set rather than List, you can use EnumSet.allOf().

Set<EnumerationClass> set = EnumSet.allOf(EnumerationClass.class);

Update: JakeRobb is right. My answer is about java.lang.Enum instead of java.util.Enumeration. Sorry for unrelated answer.

I do recommend BarcodeLibrary

Here is a small piece of code of how to use it.

        BarcodeLib.Barcode barcode = new BarcodeLib.Barcode()
        {
            IncludeLabel = true,
            Alignment = AlignmentPositions.CENTER,
            Width = 300,
            Height = 100,
            RotateFlipType = RotateFlipType.RotateNoneFlipNone,
            BackColor = Color.White,
            ForeColor = Color.Black,
        };

        Image img = barcode.Encode(TYPE.CODE128B, "123456789");

Just setting json option to true, the body will contain the parsed json:

request({
  url: 'http://...',
  json: true
}, function(error, response, body) {
  console.log(body);
});

Try something like:

$post_data="dispnumber=567567567&extension=6";
$url="http://xxxxxxxx.xxx/xx/xx";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch);

echo $result;

For US Address Parsing,

I prefer using usaddress package that is available in pip for usaddress only

python3 -m pip install usaddress

You can find stats-dot-com - personally I think their are better than opta. ESPN seems don't provide data in full and do not provide live data feeds (unfortunatelly).

We've been seeking for official data feed providing for our fantasy games (solutionsforfantasysport.com) and still staying with stats-com mainly (used opta, datafactory as well)

The answer probably depends how critical it is for you to receive support and possible customization for this service.

Google can certainly do this. Look into their XML and Geocoding API's. You should be able to craft an XML message asking Google to return Map coordinates for a given address. If the address is not found (invalid), you will receive an appropriate response. Here's a useful page: http://code.google.com/apis/maps/documentation/services.html#XML_Requests

Note that Google's aim in providing the Maps API is to plot addresses on actual maps. While you can certainly use the data for other purposes, you are at the mercy of Google should one of their maps not exactly correspond to your legal or commercial address validation needs. If you paid for one of the services you mentioned, you would likely be able to receive support should certain addresses not resolve the way you expect them to.

In other words, you get what you pay for ;) . If you have the time, though, why not try implementing a Google-based solution then going from there? The API looks pretty slick, and it's free, after all.

This could help: http://finance.yahoo.com/d/quotes.csv?e=.csv&f=c4l1&s=EURUSD=X,GBPUSD=X It will return csv file:

"EUR",1.2972
"GBP",1.6034

Or if you need json: Yahoo csv parser

This is a bit dated but there may be others looking for answers to the same question. You should think about what protection spaces make sense for your APIs. For example, you may want to identify and authenticate client application access to your APIs to restrict their use to known, registered client applications. In this case, you can use the Basic authentication scheme with the client identifier as the user-id and client shared secret as the password. You don't need proprietary authentication schemes just clearly identify the one(s) to be used by clients for each protection space. I prefer only one for each protection space but the HTTP standards allow both multiple authentication schemes on each WWW-Authenticate header response and multiple WWW-Authenticate headers in each response; this will be confusing for API clients which options to use. Be consistent and clear then your APIs will be used.

Here's what I did to check if the Broadcaster is already registered, even if you close you application (finish())

Firstime running your application, send a broadcast first it will return true/false depends on if your broadcaster in still running or not.

My Broadcaster

public class NotificationReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getExtras() != null && intent.getStringExtra("test") != null){
            Log.d("onReceive","test");
            return;
        }
    }
}

My MainActivity

// init Broadcaster
private NotificationReceiver nr = new NotificationReceiver();


Intent msgrcv = new Intent("Msg");
msgrcv.putExtra("test", "testing");
boolean isRegistered = LocalBroadcastManager.getInstance(this).sendBroadcast(msgrcv);

if(!isRegistered){
    Toast.makeText(this,"Starting Notification Receiver...",Toast.LENGTH_LONG).show();
    LocalBroadcastManager.getInstance(this).registerReceiver(nr,new IntentFilter("Msg"));
}

with React router dom v4 you can use

create a scrollToTopComponent component like the one below

class ScrollToTop extends Component {
    componentDidUpdate(prevProps) {
      if (this.props.location !== prevProps.location) {
        window.scrollTo(0, 0)
      }
    }

    render() {
      return this.props.children
    }
}

export default withRouter(ScrollToTop)

or if you are using tabs use the something like the one below

class ScrollToTopOnMount extends Component {
    componentDidMount() {
      window.scrollTo(0, 0)
    }

    render() {
      return null
    }
}

class LongContent extends Component {
    render() {
      <div>
         <ScrollToTopOnMount/>
         <h1>Here is my long content page</h1>
      </div>
    }
}

// somewhere else
<Route path="/long-content" component={LongContent}/>

hope this helps for more on scroll restoration vist there docs hare react router dom scroll restoration

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

https://material.angularjs.org

Demo: https://material.angularjs.org/latest/demo/

You can use

new File("relative/path").getAbsoluteFile()

after

System.setProperty("user.dir", "/some/directory")

System.setProperty("user.dir", "C:/OtherProject");
File file = new File("data/data.csv").getAbsoluteFile();
System.out.println(file.getPath());

Will print

C:\OtherProject\data\data.csv

I used eyeD3 the other day with a lot of success. I found that it could add artwork to the ID3 tag which the other modules I looked at couldn't. You'll have to install using pip or download the tar and execute python setup.py install from the source folder.

Relevant examples from the website are below.

Reading the contents of an mp3 file containing either v1 or v2 tag info:

 import eyeD3
 tag = eyeD3.Tag()
 tag.link("/some/file.mp3")
 print tag.getArtist()
 print tag.getAlbum()
 print tag.getTitle()

Read an mp3 file (track length, bitrate, etc.) and access it's tag:

if eyeD3.isMp3File(f):
     audioFile = eyeD3.Mp3AudioFile(f)
     tag = audioFile.getTag()

Specific tag versions can be selected:

 tag.link("/some/file.mp3", eyeD3.ID3_V2)
 tag.link("/some/file.mp3", eyeD3.ID3_V1)
 tag.link("/some/file.mp3", eyeD3.ID3_ANY_VERSION)  # The default.

Or you can iterate over the raw frames:

 tag = eyeD3.Tag()
 tag.link("/some/file.mp3")
 for frame in tag.frames:
    print frame

Once a tag is linked to a file it can be modified and saved:

 tag.setArtist(u"Cro-Mags")
 tag.setAlbum(u"Age of Quarrel")
 tag.update()

If the tag linked in was v2 and you'd like to save it as v1:

 tag.update(eyeD3.ID3_V1_1)

Read in a tag and remove it from the file:

 tag.link("/some/file.mp3")
 tag.remove()
 tag.update()

Add a new tag:

 tag = eyeD3.Tag()
 tag.link('/some/file.mp3')    # no tag in this file, link returned False
 tag.header.setVersion(eyeD3.ID3_V2_3)
 tag.setArtist('Fugazi')
 tag.update()

$.fn.outerHtml = function(){
    if (this.length) {
        var div = $('<div style="display:none"></div>');
        var clone =
        $(this[0].cloneNode(false)).html(this.html()).appendTo(div);
        var outer = div.html();
        div.remove();
        return outer;
    }
    else {
        return null;
    }
};

from http://forum.jquery.com/topic/jquery-getting-html-and-the-container-element-12-1-2010

This worked for me on Chromium. The % for translate is in reference to the size of the bounding box of the element it is applied to so it perfectly gets the element to the lower right edge while not having to switch which property is used to specify it's location.

topleft {
  top: 0%;
  left: 0%;
}
bottomright {
  top: 100%;
  left: 100%;
  -webkit-transform: translate(-100%,-100%);
}

You can only access final variables from the containing class when using an anonymous class. Therefore you need to declare the variables being used final (which is not an option for you since you are changing lastPrice and price), or don't use an anonymous class.

So your options are to create an actual inner class, in which you can pass in the variables and use them in a normal fashion

or:

There is a quick (and in my opinion ugly) hack for your lastPrice and price variable which is to declare it like so

final double lastPrice[1];
final double price[1];

and in your anonymous class you can set the value like this

price[0] = priceObject.getNextPrice(lastPrice[0]);
System.out.println();
lastPrice[0] = price[0];

I had the same problem. I googled it for two days. At last I accidentally noticed that the problem was access modifier of the constructor of the Controller. I didn’t put the public key word behind the Controller’s constructor.

public class MyController : ApiController
    {
        private readonly IMyClass _myClass;

        public MyController(IMyClass myClass)
        {
            _myClass = myClass;
        }
    }

I add this experience as another answer maybe someone else made a similar mistake.

Welcome to C++11 and rvalue references:

#include <cassert>
#include <string>

using std::string;

void myfunc(string*&& val)
{
    assert(&val);
    assert(val);
    assert(val->c_str());
    // Do stuff to the string pointer
}

// sometime later 
int main () {
    // ...
    string s;
    myfunc(&s);
    // ...
}

Now you have access to the value of the pointer (referred to by val), which is the address of the string.

You can modify the pointer, and no one will care. That is one aspect of what an rvalue is in the first place.

Be careful: The value of the pointer is only valid until myfunc() returns. At last, its a temporary.

We use generate as rails generate app. So regenerating any generate statement can be reversed using destroy statement. Just replace generate with destroy i.e. rails generate app can be written as rails destroy app' rails generate ____asrails destroy ____`

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

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

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

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

and then

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

A problem I was running into was that I was using the webpack-simple install for VueJS which didn't seem to include an Environment variable config folder. So I wasn't able to edit the env.test,development, and production.js config files. Creating them didn't help either.

Other answers weren't detailed enough for me, so I just "fiddled" with webpack.config.js. And the following worked just fine.

So to get Environment Variables to work, the webpack.config.js should have the following at the bottom:

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

Based on the above, in production, you would be able to get the NODE_ENV variable

mounted() {
  console.log(process.env.NODE_ENV)
}

Now there may be better ways to do this, but if you want to use Environment Variables in Development you would do something like the following:

if (process.env.NODE_ENV === 'development') {

  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"development"'
      }
    })
  ]);

} 

Now if you want to add other variables with would be as simple as:

if (process.env.NODE_ENV === 'development') {

  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"development"',
        ENDPOINT: '"http://localhost:3000"',
        FOO: "'BAR'"
      }
    })
  ]);
}

I should also note that you seem to need the "''" double quotes for some reason.

So, in Development, I can now access these Environment Variables:

mounted() {
  console.log(process.env.ENDPOINT)
  console.log(process.env.FOO)
}

Here is the whole webpack.config.js just for some context:

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          'vue-style-loader',
          'css-loader'
        ],
      },      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
          }
          // other vue-loader options go here
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'file-loader',
        options: {
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    },
    extensions: ['*', '.js', '.vue', '.json']
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true,
    overlay: true
  },
  performance: {
    hints: false
  },
  devtool: '#eval-source-map'
}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

if (process.env.NODE_ENV === 'development') {

  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"development"',
        ENDPOINT: '"http://localhost:3000"',
        FOO: "'BAR'"
      }
    })
  ]);

}

Eventually what solved the issue was:

1. Clean every project individually (Right click> Clean).
2. Rebuild every project individually (Right click> Rebuild).
3. Rebuild the startup project.

I guess for some reason, just cleaning the solution had a different effect than specifically cleaning every project individually.

Edit:
As per @maplemale comment, It seems that sometimes removing and re-adding each reference is also required.

Update 2019:
This question got a lot of traffic in the past, but it seems that since VS 2017 was released, it got much less attention.
So another suggestion would be - Update to a newer version of VS (>= 2017) and among other new features this issue will also be solved

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

    """
    def __init__(self, enums):
        if isinstance(enums, dict):
            self.__dict__.update(enums)
        elif isinstance(enums, list) or isinstance(enums, tuple):
            self.__dict__.update(**dict((v,k) for k,v in enumerate(enums)))
        else:

    def __contains__(self, key):
        return key in self.__dict__.values()

if __name__ == '__main__':
    print('Using a dictionary to create Enum:')
    Letters = Enum(dict((v,k) for k,v in enumerate(list('abcde'))))
    a = Letters.a

    print('\tLength of Letters enum:', len(Letters))

    print('\nUsing a list to create Enum:')
    Letters = Enum(list('abcde'))

        Failure = Enum('This is a Failure')

Since Python is a strongly typed language, concatenating a string and an integer as you may do in Perl makes no sense, because there's no defined way to "add" strings and numbers to each other.

Explicit is better than implicit.

...says "The Zen of Python", so you have to concatenate two string objects. You can do this by creating a string from the integer using the built-in str() function:

>>> "abc" + str(9)
'abc9'

Alternatively use Python's string formatting operations:

>>> 'abc%d' % 9
'abc9'

Perhaps better still, use str.format():

>>> 'abc{0}'.format(9)
'abc9'

The Zen also says:

There should be one-- and preferably only one --obvious way to do it.

Which is why I've given three options. It goes on to say...

Although that way may not be obvious at first unless you're Dutch.

The CSS tag 'margin' is actually a shorthand for the four separate margin values, top/left/bottom/right. Use css('marginTop'), etc. - note they will have 'px' on the end if you have specified them that way.

Use parseInt() around the result to turn it in to the number value.

NB. As noted by Omaty, the order of the shorthand 'margin' tag is: top right bottom left - the above list was not written in a way intended to be the list order, just a list of that specified in the tag.

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

The Javadoc for String reveals that String.split() is what you're looking for in regard to explode.

Java does not include a "implode" of "join" equivalent. Rather than including a giant external dependency for a simple function as the other answers suggest, you may just want to write a couple lines of code. There's a number of ways to accomplish that; using a StringBuilder is one:

String foo = "This,that,other";
String[] split = foo.split(",");
StringBuilder sb = new StringBuilder();
for (int i = 0; i < split.length; i++) {
    sb.append(split[i]);
    if (i != split.length - 1) {
        sb.append(" ");
    }
}
String joined = sb.toString();

vertical-align: text-bottom;

Tested, this worked for me perfectly, just apply this to the image.

To fix your issue, i have made few changes in bla.js and it is working,

var foo= function (req, res, next) {
  console.log('inside foo');
  return ("foo");
}

var  bar= function(req, res, next) {
  this.foo();
}
module.exports = {bar,foo};

and no modification in app.js

var bla = require('./bla.js');
console.log(bla.bar());

If you want/need to do it without int:

sum(int(c) * (2 ** i) for i, c in enumerate(s[::-1]))

This reverses the string (s[::-1]), gets each character c and its index i (for i, c in enumerate(), multiplies the integer of the character (int(c)) by two to the power of the index (2 ** i) then adds them all together (sum()).

I believe you need to make sure that all the container div tags above the 100% height div also has 100% height set on them including the body tag and html.

You can implement ApplicationContextAware or just use @Autowired:

public class SpringBean {
  @Autowired
  private ApplicationContext appContext;
}

SpringBean will have ApplicationContext injected, within which this bean is instantiated. For example if you have web application with a pretty standard contexts hierarchy:

main application context <- (child) MVC context

and SpringBean is declared within main context, it will have main context injected; otherwise, if it's declared within MVC context, it will have MVC context injected.

No, there is no way to do this with git show. But it would certainly be nice sometimes, and it would probably be relatively easy to implement in the git source code (after all, you just have to tell it to not trim out what it thinks is extraneous output), so the patch to do so would probably be accepted by the git maintainers.

Be careful what you wish for, though; merging a branch with a one-line change that was forked three months ago will still have a huge diff versus the mainline, and so such a full diff would be almost completely unhelpful. That's why git doesn't show it.

I've seen this error in a similar situation to mentioned in Joe's answer:

description: Too high 5xx responses rate: {{ .Value }} > 0.05

We have a colon in description value. So, the problem is in missing quotes around description value. It can be resolved by adding quotes:

description: 'Too high 5xx responses rate: {{ .Value }} > 0.05'

var theString = "TEST";
char[] myChar = theString.ToCharArray();

I tested this in the C# interactive window of Visual Studio 2019 and got:

char[4] { 'T', 'E', 'S', 'T' }

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Adding _CRT_SECURE_NO_WARNINGS to Project -> Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions didn't work for me, don't know why.

The following hint works: In stdafx.h file, please add

#define _CRT_SECURE_NO_DEPRECATE

before include other header files.

This one worked in my python script:

print "\t%-5s %-10s %-10s %-10s %-10s %-10s %-20s"  % (thread[0],thread[1],thread[2],thread[3],thread[4],thread[5],thread[6])

Whether to use comma or period for the decimal separator is entirely up to the browser. The browser makes it decision based on the locale of the operating system or browser, or some browsers take hints from the website. I made a browser comparison chart showing how different browsers support handle different localization methods. Safari being the only browser that handle commas and periods interchangeably.

Basically, you as a web author cannot really control this. Some work-arounds involves using two input fields with integers. This allows every user to input the data as yo expect. Its not particular sexy, but it will work in every case for all users.

It looks like you're passing in Null for every argument except for PropertyValueID and DropDownOptionID, right? I don't think any of your IF statements will fire if only these two values are not-null. In short, I think you have a logic error.

Other than that, I would suggest two things...

First, instead of testing for NULL, use this kind syntax on your if statements (it's safer)...

    ELSE IF ISNULL(@UnitValue, 0) != 0 AND ISNULL(@UnitOfMeasureID, 0) = 0

Second, add a meaningful PRINT statement before each UPDATE. That way, when you run the sproc in MSSQL, you can look at the messages and see how far it's actually getting.

As of 2016, you're supposed to use Array.findIndex (an ES2015/ES6 standard) for this:

a = [_x000D_
  {prop1:"abc",prop2:"qwe"},_x000D_
  {prop1:"bnmb",prop2:"yutu"},_x000D_
  {prop1:"zxvz",prop2:"qwrq"}];_x000D_
    _x000D_
index = a.findIndex(x => x.prop2 ==="yutu");_x000D_
_x000D_
console.log(index);

It's supported in Google Chrome, Firefox and Edge. For Internet Explorer, there's a polyfill on the linked page.

Performance note

Function calls are expensive, therefore with really big arrays a simple loop will perform much better than findIndex:

let test = [];_x000D_
_x000D_
for (let i = 0; i < 1e6; i++)_x000D_
    test.push({prop: i});_x000D_
_x000D_
_x000D_
let search = test.length - 1;_x000D_
let count = 100;_x000D_
_x000D_
console.time('findIndex/predefined function');_x000D_
    let fn = obj => obj.prop === search;_x000D_
_x000D_
    for (let i = 0; i < count; i++)_x000D_
        test.findIndex(fn);_x000D_
console.timeEnd('findIndex/predefined function');_x000D_
_x000D_
_x000D_
console.time('findIndex/dynamic function');_x000D_
    for (let i = 0; i < count; i++)_x000D_
        test.findIndex(obj => obj.prop === search);_x000D_
console.timeEnd('findIndex/dynamic function');_x000D_
_x000D_
_x000D_
console.time('loop');_x000D_
    for (let i = 0; i < count; i++) {_x000D_
        for (let index = 0; index < test.length; index++) {_x000D_
            if (test[index].prop === search) {_x000D_
                break;_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
console.timeEnd('loop');

As with most optimizations, this should be applied with care and only when actually needed.

<EditText

Simplest and the best solution for this is :

Add this #scrollMe [scrollTop]="scrollMe.scrollHeight" simple thing on Template side

<div style="overflow: scroll; height: xyz;" #scrollMe [scrollTop]="scrollMe.scrollHeight">
    <div class="..." 
        *ngFor="..."
        ...>  
    </div>
</div>

Turn on less secure apps for your account: https://www.google.com/settings/security/lesssecureapps

"location" : null // this is not really an array it's a null object
"location" : []   // this is an empty array

It looks like this API returns null when there is no location defined - instead of returning an empty array, not too unusual really - but they should tell you if they're going to do this.

package-lock.json: It contains the exact version details that is currently installed for your Application.

Replace this line cell.labelTitle.text = "This is a title"
with cell.labelTitle?.text = "This is a title"

And for webkit enabled browsers I've had good results with:

.myElement {
    -webkit-overflow-scrolling: touch;
    scroll-behavior: smooth; // Added in from answer from Felix
    overflow-x: scroll;
}

This makes scrolling behave much more like the standard browser behavior - at least it works well on the iPhone we were testing on!

Hope that helps,

In my case, I couldn't get the error message in my PHP script no matter what I do (error_get_last(), or ini_set('display_errors',1);) don't show the error message

according to this post

The return value from $mail refers only to whether or not your server's mailing system accepted the message for delivery, and does not and can not in any way know whether or not you are providing valid arguments. For example, the return value would be false if sendmail failed to load (e.g. if it wasn't installed properly), but would return true if sendmail loaded properly but the recipient address doesn't exist.

I confirm this because after some failed attempts to use mail() in my PHP scripts, it turns that sendmail was not installed on my machine, however the php.ini variable sendmail_path was /usr/sbin/sendmail -t -i

1- I installed sendmail from my package manager shell> dnf install sendmail

2- I started it shell> service sendmail start

3- Now if any PHP mail() function fails I find the errors of the sendmail program logged under /var/mail/ directory. 1 file per user

For example this snippet is taken from my /var/mail/root file

Recently I had the same problem to include QR image/png in email. The QR image is a byte array which is generated using ZXing. We do not want to save it to a file because saving/reading from a file is too expensive (slow). So both of the answers above do not work for me. Here's what I did to solve this problem:

import javax.mail.util.ByteArrayDataSource;
import org.apache.commons.mail.ImageHtmlEmail;
...
ImageHtmlEmail email = new ImageHtmlEmail();
byte[] qrImageBytes = createQRCode(); // get your image byte array
ByteArrayDataSource qrImageDataSource = new ByteArrayDataSource(qrImageBytes, "image/png");
String contentId = email.embed(qrImageDataSource, "QR Image");

Let's say the contentId is "111122223333", then your HTML part should have this:

<img src="cid: 111122223333">

There's no need to convert the byte array to Base64 because Commons Mail does the conversion for you automatically. Hope this helps.

That will only work for small numbers and I'm guessing it's also implementation-dependent. Python uses the same object instance for small numbers (iirc <256), but this changes for bigger numbers.

>>> a = 2104214124
>>> b = 2104214124
>>> a == b
True
>>> a is b
False

So you should always use == to compare numbers.

The very simplest way would be to run Eclipse CDT on the Linux Box and use either X11-Forwarding or remote desktop software such as VNC.

This, of course, is only possible when you Eclipse is present on the Linux box and your network connection to the box is sufficiently fast.

The advantage is that, due to everything being local, you won't have synchronization issues, and you don't get any awkward cross-platform issues.

If you have no eclipse on the box, you could thinking of sharing your linux working directory via SMB (or SSHFS) and access it from your windows machine, but that would require quite some setup.

Both would be better than having two copies, especially when it's cross-platform.

You can also use .map() as:

var list=[];

response.data.message.map(function(value, key) {
     list.push(value);
   });

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

(Background: I have some experience implementing C and C++ compilers.)

Variable-length arrays in C99 were basically a misstep. In order to support VLAs, C99 had to make the following concessions to common sense:

• sizeof x is no longer always a compile-time constant; the compiler must sometimes generate code to evaluate a sizeof-expression at runtime.

• Allowing two-dimensional VLAs (int A[x][y]) required a new syntax for declaring functions that take 2D VLAs as parameters: void foo(int n, int A[][*]).

• Less importantly in the C++ world, but extremely important for C's target audience of embedded-systems programmers, declaring a VLA means chomping an arbitrarily large chunk of your stack. This is a guaranteed stack-overflow and crash. (Anytime you declare int A[n], you're implicitly asserting that you have 2GB of stack to spare. After all, if you know "n is definitely less than 1000 here", then you would just declare int A[1000]. Substituting the 32-bit integer n for 1000 is an admission that you have no idea what the behavior of your program ought to be.)

Okay, so let's move to talking about C++ now. In C++, we have the same strong distinction between "type system" and "value system" that C89 does… but we've really started to rely on it in ways that C has not. For example:

template<typename T> struct S { ... };
int A[n];
S<decltype(A)> s;  // equivalently, S<int[n]> s;

If n weren't a compile-time constant (i.e., if A were of variably modified type), then what on earth would be the type of S? Would S's type also be determined only at runtime?

What about this:

template<typename T> bool myfunc(T& t1, T& t2) { ... };
int A1[n1], A2[n2];
myfunc(A1, A2);

The compiler must generate code for some instantiation of myfunc. What should that code look like? How can we statically generate that code, if we don't know the type of A1 at compile time?

Worse, what if it turns out at runtime that n1 != n2, so that !std::is_same<decltype(A1), decltype(A2)>()? In that case, the call to myfunc shouldn't even compile, because template type deduction should fail! How could we possibly emulate that behavior at runtime?

Basically, C++ is moving in the direction of pushing more and more decisions into compile-time: template code generation, constexpr function evaluation, and so on. Meanwhile, C99 was busy pushing traditionally compile-time decisions (e.g. sizeof) into the runtime. With this in mind, does it really even make sense to expend any effort trying to integrate C99-style VLAs into C++?

As every other answerer has already pointed out, C++ provides lots of heap-allocation mechanisms (std::unique_ptr<int[]> A = new int[n]; or std::vector<int> A(n); being the obvious ones) when you really want to convey the idea "I have no idea how much RAM I might need." And C++ provides a nifty exception-handling model for dealing with the inevitable situation that the amount of RAM you need is greater than the amount of RAM you have. But hopefully this answer gives you a good idea of why C99-style VLAs were not a good fit for C++ — and not really even a good fit for C99. ;)

For more on the topic, see N3810 "Alternatives for Array Extensions", Bjarne Stroustrup's October 2013 paper on VLAs. Bjarne's POV is very different from mine; N3810 focuses more on finding a good C++ish syntax for the things, and on discouraging the use of raw arrays in C++, whereas I focused more on the implications for metaprogramming and the typesystem. I don't know if he considers the metaprogramming/typesystem implications solved, solvable, or merely uninteresting.

A good blog post that hits many of these same points is "Legitimate Use of Variable Length Arrays" (Chris Wellons, 2019-10-27).

It enables error handling. The following is partly from https://msdn.microsoft.com/en-us/library/5hsw66as.aspx

' Enable error handling. When a run-time error occurs, control goes to the statement 
' immediately following the statement where the error occurred, and execution
' continues from that point.
On Error Resume Next

SomeCodeHere

If Err.Number = 0 Then
    WScript.Echo "No Error in SomeCodeHere."
Else
  WScript.Echo "Error in SomeCodeHere: " & Err.Number & ", " & Err.Source & ", " & Err.Description
  ' Clear the error or you'll see it again when you test Err.Number
  Err.Clear
End If

SomeMoreCodeHere

If Err.Number <> 0 Then
  WScript.Echo "Error in SomeMoreCodeHere:" & Err.Number & ", " & Err.Source & ", " & Err.Description
  ' Clear the error or you'll see it again when you test Err.Number
  Err.Clear
End If

' Disables enabled error handler in the current procedure and resets it to Nothing.
On Error Goto 0

' There are also `On Error Goto -1`, which disables the enabled exception in the current 
' procedure and resets it to Nothing, and `On Error Goto line`, 
' which enables the error-handling routine that starts at the line specified in the 
' required line argument. The line argument is any line label or line number. If a run-time 
' error occurs, control branches to the specified line, making the error handler active. 
' The specified line must be in the same procedure as the On Error statement, 
' or a compile-time error will occur.

Actually, his example won't work (although at first I thought that it would, too). Based on the help for the Start command, the first parameter is the name of the newly created Command Prompt window, and the second and third should be the path to the application and its parameters, respectively. If you add another "" before path to the app, it should work (at least it did for me). Use something like this:

start "" "c:\path with spaces\app.exe" param1 "param with spaces"

You can change the first argument to be whatever you want the title of the new command prompt to be. If it's a Windows app that is created, then the command prompt won't be displayed, and the title won't matter.

You can use the createRef to change the state of the child component from the parent component. Here are all the steps.

1. Create a method to change the state in the child component.

   2 - Create a reference for the child component in parent component using React.createRef().

   3 - Attach reference with the child component using ref={}.

   4 - Call the child component method using this.yor-reference.current.method.

Parent component

class ParentComponent extends Component {
constructor()
{
this.changeChild=React.createRef()
}
  render() {
    return (
      <div>
        <button onClick={this.changeChild.current.toggleMenu()}>
          Toggle Menu from Parent
        </button>
        <ChildComponent ref={this.changeChild} />
      </div>
    );
  }
}

Child Component

class ChildComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      open: false;
    }
  }

  toggleMenu=() => {
    this.setState({
      open: !this.state.open
    });
  }

  render() {
    return (
      <Drawer open={this.state.open}/>
    );
  }
}

I'm am answering the question: How to get the value of a variable given its name in a string? which is closed as a duplicate with a link to this question.

If the variables in question are part of an object (part of a class for example) then some useful functions to achieve exactly that are hasattr, getattr, and setattr.

So for example you can have:

class Variables(object):
    def __init__(self):
        self.foo = "initial_variable"
    def create_new_var(self,name,value):
        setattr(self,name,value)
    def get_var(self,name):
        if hasattr(self,name):
            return getattr(self,name)
        else:
            raise("Class does not have a variable named: "+name)

Then you can do:

v = Variables()
v.get_var("foo")

"initial_variable"

v.create_new_var(v.foo,"is actually not initial")
v.initial_variable

"is actually not initial"

You can use the adjacent sibling selector to achieve something similar, that might help.

.list-item.other-class + .list-item:not(.other-class)

Will effectively target the immediately following element after the last element with the class other-class.

Throwing my comments into the ring, I just came across this after attempting to refresh my development environment after clicking DENY accidentally on one of the application requests, after searching around I found a number of things that didn't seem to work. This is the full order in which I've attempted the fixes and whether there was a success:

1) Attempted to clear the DerivedFiles and restart XCode - no dice

2) Attempted to Log and Unlock the Keychain, then restart XCode - no dice

3) Attempted to refresh my developer account within XCode - no dice

4) Bit the bullet and just reset my entire keychain, after doing so my developer account was signed out (signed back in), then restarted XCode - no dice

5) Found an article on here that said that we needed to set the [login|local|System]/certificate/Apple Worldwide Developer Relations Certificate Authority to "System default". But in my case it was already set to system default - no dice

6) Then I looked at my actual developer certificate login/my certificates/Mac Developer: and when I looked in there it was correctly set to Confirm before allowing access BUT there was no entries in the lower section. There should be [Xcode, codesign, productbuild]. I deleted the certificate entry and restarted XCode - bingo

The certificate was added and I was then prompted. So what did I do, I pressed "always allow" and then just boned myself.

I had to go back and delete the certificate again, then go through about 20 allow dialogs during a clean build. Once completed, I was able to build completely.

If your into Python or use Androguard, the Androguard Androaxml feature will do this conversion for you. The feature is detailed in this blog post, with additional documentation here and source here.

Usage:

$ ./androaxml.py -h
Usage: androaxml.py [options]

Options:
-h, --help            show this help message and exit
-i INPUT, --input=INPUT
                      filename input (APK or android's binary xml)
-o OUTPUT, --output=OUTPUT
                      filename output of the xml
-v, --version         version of the API

$ ./androaxml.py -i yourfile.apk -o output.xml
$ ./androaxml.py -i AndroidManifest.xml -o output.xml

String methodName= "...";
String[] args = {};

Method[] methods = clazz.getMethods();
for (Method m : methods) {
    if (methodName.equals(m.getName())) {
        // for static methods we can use null as instance of class
        m.invoke(null, new Object[] {args});
        break;
    }
}

The currently accepted answer is incorrect. It is NOT required to set maxBufferSize and maxReceivedMessageSize on the client and the server binding. It depends!

If your request is too large (i.e., method parameters of the service operation are memory intensive) set the properties on the server-side, if the response is too large (i.e., the method return value of the service operation is memory intensive) set the values on the client-side.

For the difference between maxBufferSize and maxReceivedMessageSize see MaxBufferSize property?.

esp is as you say it is, the top of the stack.

ebp is usually set to esp at the start of the function. Function parameters and local variables are accessed by adding and subtracting, respectively, a constant offset from ebp. All x86 calling conventions define ebp as being preserved across function calls. ebp itself actually points to the previous frame's base pointer, which enables stack walking in a debugger and viewing other frames local variables to work.

Most function prologs look something like:

push ebp      ; Preserve current frame pointer
mov ebp, esp  ; Create new frame pointer pointing to current stack top
sub esp, 20   ; allocate 20 bytes worth of locals on stack.

Then later in the function you may have code like (presuming both local variables are 4 bytes)

mov [ebp-4], eax    ; Store eax in first local
mov ebx, [ebp - 8]  ; Load ebx from second local

FPO or frame pointer omission optimization which you can enable will actually eliminate this and use ebp as another register and access locals directly off of esp, but this makes debugging a bit more difficult since the debugger can no longer directly access the stack frames of earlier function calls.

EDIT:

For your updated question, the missing two entries in the stack are:

var_C = dword ptr -0Ch
var_8 = dword ptr -8
var_4 = dword ptr -4
*savedFramePointer = dword ptr 0*
*return address = dword ptr 4*
hInstance = dword ptr  8h
PrevInstance = dword ptr  0C
hlpCmdLine = dword ptr  10h
nShowCmd = dword ptr  14h

This is because the flow of the function call is:

• Push parameters (hInstance, etc.)
• Call function, which pushes return address
• Push ebp
• Allocate space for locals

For .Net 4 use:

ServicePointManager.SecurityProtocol = (SecurityProtocolType)768 | (SecurityProtocolType)3072;

Based on the answers already provided here, this is the way I implemented it:

JFrame frame= new JFrame()
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

// frame stuffs here ...

frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING));

The JFrame gets the event to close and upon closing, exits.

Found a good solution what worked for me, check this link https://codepen.io/chriswrightdesign/pen/emQNGZ/?editors=1100 First, we add a parent div, second we change min-height:100% to min-height:100vh. It works like a charm.

// by having a parent with flex-direction:row, 
// the min-height bug in IE doesn't stick around.
.flashy-content-outer { 
    display:flex;
    flex-direction:row;
}
.flashy-content-inner {
    display:flex;
    flex-direction:column;
    justify-content:center;
    align-items:center;
    min-width:100vw;
    min-height:100vh;
    padding:20px;
    box-sizing:border-box;
}
.flashy-content {
    display:inline-block;
    padding:15px;
    background:#fff;
}  

Add the following to the eclipse.ini :

-vm


Java_Home_Variable\bin\javaw.exe

In my Case its

-vm

H:\usr\java\jdk1.6.0_16\bin\javaw.exe

You can generate script from Task menu

There is an issue that if you close the dialog it will execute the onCloseCallback function. This is a better design.

function jAlert2(outputMsg, titleMsg, onCloseCallback) {
    if (!titleMsg)
        titleMsg = 'Alert';

    if (!outputMsg)
        outputMsg = 'No Message to Display.';

    $("<div></div>").html(outputMsg).dialog({
        title: titleMsg,
        resizable: false,
        modal: true,
        buttons: {
            "OK": onCloseCallback,
            "Cancel": function() {
          $( this ).dialog( "destroy" );
            }

        },
    });

As mentioned above markdown itself leaves you hanging on this. However, depending on the implementation there are some workarounds:

At least one version of MD considers <div> to be a block level tag but <DIV> is just text. All broswers however are case insensitive. This allows you to keep the syntax simplicity of MD, at the cost of adding div container tags.

So the following is a workaround:

<DIV class=foo>

  Paragraphs here inherit class foo from above.

</div>

The downside of this is that the output code has <p> tags wrapping the <div> lines (both of them, the first because it's not and the second because it doesn't match. No browser fusses about this that I've found, but the code won't validate. MD tends to put in spare <p> tags anyway.

Several versions of markdown implement the convention <tag markdown="1"> in which case MD will do the normal processing inside the tag. The above example becomes:

<div markdown="1" class=foo>

  Paragraphs here inherit class foo from above.

</div>

The current version of Fletcher's MultiMarkdown allows attributes to follow the link if using referenced links.

If you have Multiple radio buttons in single form then

var myRadio1 = $('input[name=radioButtonName1]');
var value1 = myRadio1.filter(':checked').val();

var myRadio2 = $('input[name=radioButtonName2]');
var value2 = myRadio2.filter(':checked').val();

This is working for me.

You can change the font size in R Markdown with HTML code tags <font size="1"> your text </font> . This code is added to the R Markdown document and will alter the output of the HTML output.

For example:

 <font size="1"> This is my text number1</font> _x000D_
_x000D_
 <font size="2"> This is my text number 2 </font>_x000D_
 _x000D_
 <font size="3"> This is my text number 3</font> _x000D_
 _x000D_
 <font size="4"> This is my text number 4</font> _x000D_
 _x000D_
 <font size="5"> This is my text number 5</font> _x000D_
 _x000D_
 <font size="6"> This is my text number 6</font>

Here are two ways to accept a file. One using in memory provider MultipartMemoryStreamProvider and one using MultipartFormDataStreamProvider which saves to a disk. Note, this is only for one file upload at a time. You can certainty extend this to save multiple-files. The second approach can support large files. I've tested files over 200MB and it works fine. Using in memory approach does not require you to save to disk, but will throw out of memory exception if you exceed a certain limit.

private async Task<Stream> ReadStream()
{
    Stream stream = null;
    var provider = new MultipartMemoryStreamProvider();
    await Request.Content.ReadAsMultipartAsync(provider);
    foreach (var file in provider.Contents)
    {
        var buffer = await file.ReadAsByteArrayAsync();
        stream = new MemoryStream(buffer);
    }

    return stream;
}

private async Task<Stream> ReadLargeStream()
{
    Stream stream = null;
    string root = Path.GetTempPath();
    var provider = new MultipartFormDataStreamProvider(root);
    await Request.Content.ReadAsMultipartAsync(provider);
    foreach (var file in provider.FileData)
    {
        var path = file.LocalFileName;
        byte[] content = File.ReadAllBytes(path);
        File.Delete(path);
        stream = new MemoryStream(content);
    }

    return stream;
}

The man page has very detailed descriptions of all of the various options (the status bar is highly configurable). Your best bet is to read through man tmux and pay particular attention to those options that begin with status-.

So, for example, status-bg red would set the background colour of the bar.

The three components of the bar, the left and right sections and the window-list in the middle, can all be configured to suit your preferences. status-left and status-right, in addition to having their own variables (like #S to list the session name) can also call custom scripts to display, for example, system information like load average or battery time.

The option to rename windows or panes based on what is currently running in them is automatic-rename. You can set, or disable it globally with:

setw -g automatic-rename [on | off]

The most straightforward way to become comfortable with building your own status bar is to start with a vanilla one and then add changes incrementally, reloading the config as you go.¹

You might also want to have a look around on github or bitbucket for other people's conf files to provide some inspiration. You can see mine here².

¹ You can automate this by including this line in your .tmux.conf:

bind R source-file ~/.tmux.conf \; display-message "Config reloaded..."

You can then test your new functionality with Ctrlb,Shiftr. tmux will print a helpful error message—including a line number of the offending snippet—if you misconfigure an option.

² Note: I call a different status bar depending on whether I am in X or the console - I find this quite useful.

I also found the apache commons IOUtils class , so :

InputStreamReader isr = new InputStreamReader(IOUtils.toInputStream(myString));

it work in my case, oldSensor and newSnsor - oldView and newView:

private void replaceSensors(View oldSensor, View newSensor) {
            ViewGroup parent = (ViewGroup) oldSensor.getParent();

            if (parent == null) {
                return;
            }

            int indexOldSensor = parent.indexOfChild(oldSensor);
            int indexNewSensor = parent.indexOfChild(newSensor);
            parent.removeView(oldSensor);
            parent.addView(oldSensor, indexNewSensor);
            parent.removeView(newSensor);
            parent.addView(newSensor, indexOldSensor);
        }

Using PAM is execellent.

# modify the display PAM
$ cat /etc/security/pam_env.conf 
# BEFORE: $ export DISPLAY=:0.0 && python /var/tmp/myproject/click.py &
# AFTER : $ python $abc/click.py &
DISPLAY  DEFAULT=${REMOTEHOST}:0.0 OVERRIDE=${DISPLAY}
abc   DEFAULT=/var/tmp/myproject

I just solved this issue. The problem was in version conflict. Nodejs 10 installed with npm. So before installing nodejs - remove old npm. Or remove new node -> remove npm -> install node again.

This is the only way which helped me.

Specifically if someone is facing problem in Chrome:

What you need to do to fix this is to use the onSubmit tag in the <form> element to set the submit button disabled. This will allow Chrome to disable the button immediately after it is pressed and the form submission will still go ahead...

<form name ="myform" method="POST" action="dosomething.php" onSubmit="document.getElementById('submit').disabled=true;"> 
     <input type="submit" name="submit" value="Submit" id="submit"> 
</form>

Try using a style and set colorControlActivated too desired ProgressBar color.

<style name="progressColor" parent="Widget.AppCompat.ProgressBar">
    <item name="colorControlActivated">@color/COLOR</item>
</style>

Then set the theme of the ProgressBar to new style.

<ProgressBar
    android:id="@+id/progress_bar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/progressColor"
 />

if you have GNU date and i understood you correctly

$ date +%Y:%m:%d -d "yesterday"
2009:11:09

or

$ date +%Y:%m:%d -d "1 day ago"
2009:11:09

Use

[A-Z]?

to make the letter optional. {1} is redundant. (Of course you could also write [A-Z]{0,1} which would mean the same, but that's what the ? is there for.)

You could improve your regex to

^([0-9]{5})+\s+([A-Z]?)\s+([A-Z])([0-9]{3})([0-9]{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])[0-9]{3}([0-9]{4})([0-9]{2})([0-9]{2})

And, since in most regex dialects, \d is the same as [0-9]:

^(\d{5})+\s+([A-Z]?)\s+([A-Z])(\d{3})(\d{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])\d{3}(\d{4})(\d{2})(\d{2})

But: do you really need 11 separate capturing groups? And if so, why don't you capture the fourth-to-last group of digits?

Rather give names of the column on which you want to merge:

exporttab <- merge(x=dwd_nogap, y=dwd_gap, by.x='x1', by.y='x2', fill=-9999)

So you are doing this a bit backwards. Typically you'd do something like this:

?<div class='article'>
  Article 1
</div>
<div class='article'>
  Article 2
</div>
<div class='article'>
  Article 3
</div>?

And then in your jQuery:

$('.article').click(function(){
    article = $(this).text(); //$(this) is what you clicked!
    });?

When I see things like #search-item .search-article, #search-item .search-article, and #search-item .search-article I sense you are overspecifying your CSS which makes writing concise jQuery very difficult. This should be avoided if at all possible.

You can use the jquery .length property

var numItems = $('.item').length;

You can do it fast, only using one POSIX function. If you have bunch of tasks with dates, see the module DateTime.

use POSIX qw(strftime);

my $date = strftime "%m/%d/%Y", localtime;
print $date;

I create a method to simplify this:

    public static void drawCenterText(String text, RectF rectF, Canvas canvas, Paint paint) {
    Paint.Align align = paint.getTextAlign();
    float x;
    float y;
    //x
    if (align == Paint.Align.LEFT) {
        x = rectF.centerX() - paint.measureText(text) / 2;
    } else if (align == Paint.Align.CENTER) {
        x = rectF.centerX();
    } else {
        x = rectF.centerX() + paint.measureText(text) / 2;
    }
    //y
    metrics = paint.getFontMetrics();
    float acent = Math.abs(metrics.ascent);
    float descent = Math.abs(metrics.descent);
    y = rectF.centerY() + (acent - descent) / 2f;
    canvas.drawText(text, x, y, paint);

    Log.e("ghui", "top:" + metrics.top + ",ascent:" + metrics.ascent
            + ",dscent:" + metrics.descent + ",leading:" + metrics.leading + ",bottom" + metrics.bottom);
}

rectF is the area you want draw the text,That's it. Details

Use a Temp Table or a Table variable, e.g.

select 'A' as [value]
into #tmp
union
select 'B'
union 
select 'C'

and then

SELECT   
blah 
FROM    foo 
WHERE   myField IN (select [value] from #tmp) 

or

SELECT   
f.blah 
FROM foo f INNER JOIN #tmp t ON f.myField = t.[value]

The Like Box/ Page plugin is basically an iframe and ugly :D

So I created my own free plugin that I call Famax plugin to display FanPage feeds. It's similar to the like box but has a better UI and is more customizable.

Also because the Like box is shown in an iframe with a fixed width and height etc, its not really responsive.

NVM (Node Version manager)

https://github.com/nvm-sh/nvm

Advantages:

• allows you to use multiple versions of Node and without sudo

• is analogous to Ruby RVM and Python Virtualenv, widely considered best practice in Ruby and Python communities

• downloads a pre-compiled binary where possible, and if not it downloads the source and compiles one for you

Tested in Ubuntu 17.10:

curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | sh
source ~/.nvm/nvm.sh
nvm install 0.9.0
nvm install 0.9.9
nvm use 0.9.0
node --version
#v0.9.0
nvm use 0.9.9
node --version
#v0.9.9

For the particular case of the most recent long term support version (recommended if you can choose):

nvm install --lts
nvm use --lts
npm --version
npm install --global vaca
vaca

Since the sourcing has to be done for every new shell, the install script hacks adds some auto sourcing to the end of your .barshrc. That works, but I prefer to remove the auto-added one and add my own:

f="$HOME/.nvm/nvm.sh"
if [ -r "$f" ]; then
  . "$f" &>'/dev/null'
  nvm use --lts &>'/dev/null'
fi

With this setup, you get for example:

which node

gives:

/home/ciro/.nvm/versions/node/v0.9.0/bin/node

and:

which vaca

gives:

/home/ciro/.nvm/versions/node/v0.9.0/bin/vaca

and if we want to use the globally installed module:

npm link vaca
node -e 'console.log(require.resolve("vaca"))'

gives:

/home/ciro/.nvm/versions/node/v0.9.0/lib/node_modules/vaca/index.js

• NodeJS require a global module/package
• How do I import global modules in Node? I get "Error: Cannot find module <module>"?

so we see that everything is completely contained inside the specific node version.

Edit: CMake now has builtin support for this. See new answer.

You can also force the build of the dependent target in a secondary make process

See my answer on a related topic.

#multiplying each element in the list and adding it into an empty list
original = [1, 2, 3]
results = []
for num in original:
    results.append(num*2)# multiply each iterative number by 2 and add it to the empty list.

print(results)

You will either need LESS or SASS for the same..

But here is another alternative which I believe will work out in CSS3..

http://css3.bradshawenterprises.com/blog/css-variables/

Example :

 :root {
    -webkit-var-beautifulColor: rgba(255,40,100, 0.8);
    -moz-var-beautifulColor: rgba(255,40,100, 0.8);
    -ms-var-beautifulColor: rgba(255,40,100, 0.8);
    -o-var-beautifulColor: rgba(255,40,100, 0.8);
    var-beautifulColor: rgba(255,40,100, 0.8);
 }
  .example1 h1 {
    color: -webkit-var(beautifulColor);
    color: -moz-var(beautifulColor);
    color: -ms-var(beautifulColor);
    color: -o-var(beautifulColor);
    color: var(beautifulColor);
 }

STATICFILES_DIRS: You can keep the static files for your project here e.g. the ones used by your templates.

STATIC_ROOT: leave this empty, when you do manage.py collectstatic, it will search for all the static files on your system and move them here. Your static file server is supposed to be mapped to this folder wherever it is located. Check it after running collectstatic and you'll find the directory structure django has built.

--------Edit----------------

As pointed out by @DarkCygnus, STATIC_ROOT should point at a directory on your filesystem, the folder should be empty since it will be populated by Django.

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

or

STATIC_ROOT = '/opt/web/project/static_files'

--------End Edit -----------------

STATIC_URL: '/static/' is usually fine, it's just a prefix for static files.

A riff on the great answer by @Emilie, not a replacement/competing answer.
(Xcode6-Beta5)

var original    = "This is a test"
var replacement = "!"

var startIndex = advance(original.startIndex, 1) // Start at the second character
var endIndex   = advance(startIndex, 2) // point ahead two characters
var range      = Range(start:startIndex, end:endIndex)
var final = original.stringByReplacingCharactersInRange(range, withString:replacement)

println("start index: \(startIndex)")
println("end index:   \(endIndex)")
println("range:       \(range)")
println("original:    \(original)")
println("final:       \(final)")

Output:

start index: 4
end index:   7
range:       4..<7
original:    This is a test
final:       !his is a test

Notice the indexes account for multiple code units. The flag (REGIONAL INDICATOR SYMBOL LETTERS ES) is 8 bytes and the (FACE WITH TEARS OF JOY) is 4 bytes. (In this particular case it turns out that the number of bytes is the same for UTF-8, UTF-16 and UTF-32 representations.)

Wrapping it in a func:

func replaceString(#string:String, #with:String, #start:Int, #length:Int) ->String {
    var startIndex = advance(original.startIndex, start) // Start at the second character
    var endIndex   = advance(startIndex, length) // point ahead two characters
    var range      = Range(start:startIndex, end:endIndex)
    var final = original.stringByReplacingCharactersInRange(range, withString: replacement)
    return final
}

var newString = replaceString(string:original, with:replacement, start:1, length:2)
println("newString:\(newString)")

Output:

newString: !his is a test

Since Android Studio 3.4, there is a new tool called Resource manager. It supports importing many drawables at once (vectors, pngs, ...) . Follow the official documentation.

js version, catches iPad too:

var is_mobile = /mobile|android/i.test (navigator.userAgent);

There is an even easier way that does not involve writing anything in the code behind: Just add this line to your javascript:

if(<%=(Not Page.IsPostBack).ToString().ToLower()%>){//Your JavaScript goodies here}

or

if(<%=(Page.IsPostBack).ToString().ToLower()%>){//Your JavaScript goodies here}

Probably your simple json.jar file isn't in your classpath.

If you want to know how many values match in both the dictionaries, you should have said that :)

Maybe something like this:

shared_items = {k: x[k] for k in x if k in y and x[k] == y[k]}
print len(shared_items)

My solution:

I had wamp x32 installed before, needed to remove and then installed the x64, receiving the same message "The mbstring extension is missing. Please check your PHP configuration.".

On php.ini, all references to wamp, such as extension_dir = were pointing to "C:/Program Files/Wamp/...". Check all paths, the correct for me is "C:/Wamp64/". Restart services and it's all right now.

I had this issue and what I did and solved the problem was that I used AsEnumerable() just before my Join clause. here is my query:

List<AccountViewModel> selectedAccounts;

 using (ctx = SmallContext.GetInstance()) {
                var data = ctx.Transactions.
                    Include(x => x.Source).
                    Include(x => x.Relation).
                    AsEnumerable().
                    Join(selectedAccounts, x => x.Source.Id, y => y.Id, (x, y) => x).
                    GroupBy(x => new { Id = x.Relation.Id, Name = x.Relation.Name }).
                    ToList();
            }

I was wondering why this issue happens, and now I think It is because after you make a query via LINQ, the result will be in memory and not loaded into objects, I don't know what that state is but they are in in some transitional state I think. Then when you use AsEnumerable() or ToList(), etc, you are placing them into physical memory objects and the issue is resolving.

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

Removing double quotes:

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

Removing different kinds of brackets:

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

-d stands for "delete".

Why your code does not work?

The where method returns an ActiveRecord::Relation object (acts like an array which contains the results of the where), it can be empty but it will never be nil.

Business.where(id: -1) 
 #=> returns an empty ActiveRecord::Relation ( similar to an array )
Business.where(id: -1).nil? # ( similar to == nil? )
 #=> returns false
Business.where(id: -1).empty? # test if the array is empty ( similar to .blank? )
 #=> returns true

How to test if at least one record exists?

Option 1: Using .exists?

if Business.exists?(user_id: current_user.id)
  # same as Business.where(user_id: current_user.id).exists?
  # ...
else
  # ...
end

Option 2: Using .present? (or .blank?, the opposite of .present?)

if Business.where(:user_id => current_user.id).present?
  # less efficiant than using .exists? (see generated SQL for .exists? vs .present?)
else
  # ...
end

Option 3: Variable assignment in the if statement

if business = Business.where(:user_id => current_user.id).first
  business.do_some_stuff
else
  # do something else
end

This option can be considered a code smell by some linters (Rubocop for example).

Option 3b: Variable assignment

business = Business.where(user_id: current_user.id).first
if business
  # ...
else
  # ...
end

You can also use .find_by_user_id(current_user.id) instead of .where(...).first

Best option:

• If you don't use the Business object(s): Option 1
• If you need to use the Business object(s): Option 3

After correcting the JSON this should work for you now:

var array = [{id: 1, date:'Mar 12 2012 10:00:00 AM'}, {id: 2, date:'Mar 8 2012 08:00:00 AM'}];


array.sort(function(a, b) {
    var c = new Date(a.date);
    var d = new Date(b.date);
    return c-d;
});

The EclipsePasteAsJavaString plug-in allows you to insert text as a Java string by Ctrl + Shift + V

Example

Paste as usual via Ctrl+V:

some text with tabs and new lines

Paste as Java string via Ctrl+Shift+V

"some text\twith tabs\r\n" + "and new \r\n" + "lines"

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

The correct php way is to use parse_url()

http://php.net/manual/en/function.parse-url.php

(from php manual)

This function parses a URL and returns an associative array containing any of the various components of the URL that are present.

This function is not meant to validate the given URL, it only breaks it up into the above listed parts. Partial URLs are also accepted, parse_url() tries its best to parse them correctly.

There are 4 main factors into why you would want to use synchronized or java.util.concurrent.Lock.

Note: Synchronized locking is what I mean when I say intrinsic locking.

1. When Java 5 came out with ReentrantLocks, they proved to have quite a noticeble throughput difference then intrinsic locking. If youre looking for faster locking mechanism and are running 1.5 consider j.u.c.ReentrantLock. Java 6's intrinsic locking is now comparable.

2. j.u.c.Lock has different mechanisms for locking. Lock interruptable - attempt to lock until the locking thread is interrupted; timed lock - attempt to lock for a certain amount of time and give up if you do not succeed; tryLock - attempt to lock, if some other thread is holding the lock give up. This all is included aside from the simple lock. Intrinsic locking only offers simple locking

3. Style. If both 1 and 2 do not fall into categories of what you are concerned with most people, including myself, would find the intrinsic locking semenatics easier to read and less verbose then j.u.c.Lock locking.
4. Multiple Conditions. An object you lock on can only be notified and waited for a single case. Lock's newCondition method allows for a single Lock to have mutliple reasons to await or signal. I have yet to actually need this functionality in practice, but is a nice feature for those who need it.

Both Query is used for round down the nearest integer in MySQL

1. SELECT FLOOR(445.6) ;
2. SELECT NULL(222.456);

Just a quick addition. If you're using the new analytics.js, then:

var track = function() {     
 ga('send', 'pageview', {'page': $location.path()});                
};

Additionally one tip is that google analytics will not fire on localhost. So if you are testing on localhost, use the following instead of the default create (full documentation)

ga('create', 'UA-XXXX-Y', {'cookieDomain': 'none'});

A pointer is a "reference" to a value.. much like a library call number is a reference to a book. "Dereferencing" the call number is physically going through and retrieving that book.

int a=4 ;
int *pA = &a ;
printf( "The REFERENCE/call number for the variable `a` is %p\n", pA ) ;

// The * causes pA to DEREFERENCE...  `a` via "callnumber" `pA`.
printf( "%d\n", *pA ) ; // prints 4.. 

If the book isn't there, the librarian starts shouting, shuts the library down, and a couple of people are set to investigate the cause of a person going to find a book that isn't there.

It's a textual encoding of binary data where the resultant text has nothing but letters, numbers and the symbols "+", "/" and "=". It's a convenient way to store/transmit binary data over media that is specifically used for textual data.

But why Base-64? The two alternatives for converting binary data into text that immediately spring to mind are:

1. Decimal: store the decimal value of each byte as three numbers: 045 112 101 037 etc. where each byte is represented by 3 bytes. The data bloats three-fold.
2. Hexadecimal: store the bytes as hex pairs: AC 47 0D 1A etc. where each byte is represented by 2 bytes. The data bloats two-fold.

Base-64 maps 3 bytes (8 x 3 = 24 bits) in 4 characters that span 6-bits (6 x 4 = 24 bits). The result looks something like "TWFuIGlzIGRpc3Rpb...". Therefore the bloating is only a mere 4/3 = 1.3333333 times the original.

The difference is that on the

foreach($featured as $key => $value){
 echo $value['name'];
}

you are able to manipulate the value of each iteration's $key from their key-value pair. Like @djiango answered, if you are not manipulating each value's $key, the result of the loop will be exactly the same as

foreach($featured as $value) {
  echo $value['name']
}

Source: You can read it from the PHP Documentation:

The first form loops over the array given by array_expression. On each iteration, the value >of the current element is assigned to $value and the internal array pointer is advanced by >one (so on the next iteration, you'll be looking at the next element).*

The second form will additionally assign the current element's key to the $key variable on >each iteration.

If the data you are manipulating is, say, arrays with custom keys, you could print them to screen like so:

$array = ("name" => "Paul", "age" => 23);

foreach($featured as $key => $value){
 echo $key . "->" . $value;
}

Should print:

name->Paul

age->23

And you wouldn't be able to do that with a foreach($featured as $value) with the same ease. So consider the format above a convenient way to manipulate keys when needed.

To inject an Object, its class must be known to the CDI mechanism. Usualy adding the @Named annotation will do the trick.

I have just downloaded Tomcat and want to stop it (Windows).

1. To stop tomcat

   • run cmd as administrator (I used Cmder)

   • find process ID

tasklist /fi "Imagename eq tomcat*"

C:\Users\Admin
tasklist /fi "Imagename eq tomcat*"

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
Tomcat8aaw.exe                6376 Console                    1      7,300 K
Tomcat8aa.exe                 5352 Services                   0    124,748 K

• stop prosess with pid 6376

C:\Users\Admin

taskkill /f /pid 6376

SUCCESS: The process with PID 6376 has been terminated.

• stop process with pid 5352

C:\Users\Admin

taskkill /f /pid 5352

SUCCESS: The process with PID 5352 has been terminated.

I ran into this problem, however while running the command:

Install-Package -IncludePrerelease Microsoft.AspNet.Web.Optimization 

I received the cryptic message (gotta love a great pun before the first cup of coffee):

Install-Package : The specified cryptographic algorithm is not supported on this platform.

I am running this on Windows XP SP3 (not by choice) and what I found was that I had to follow the instructions posted by the user artsnob on the ASP.NET Forum

• Please uninstall the Nuget and try re-installing it. If you are unable to do this, login as an Administrator.
• Go to Tools=> Extension Manager => Select "Nuget Package Manager" => UnInstall
• Install it again, by searching "Nuget" => Install.
• If it did not work, please try installing, 1.7.x version as I mentioned in the previous post (It doesn't mean, you have to use the previous version, if it works fine, we can report this bug, and get the patches for the latest version).

Once I ran this I could then run the command line to update the Web.Optimization.

Hope this saves someone some digging.

Your firewall does not allow any new connection to share information without your consent. ONLY thing to do is give your consent to your firewall.

1. Go to Firewall settings in Control Panel

2. Click on Advanced Settings

3. Click on Inbound Rules and Add a new rule.

4. Choose 'Type Of Rule' to Port.

5. Allow this for All Programs.

6. Allow this rule to be applied on all Profiles i.e. Domain, Private, Public.

7. Give this rule any name.

I had the problem of expressing newline with \n or \r\n.
Magically the character \r which is used for carriage return worked for me like a newline.
So in some cases, it is useful to consider \r too.

This worked for me:

git cherry -v 

As indicated at Git: See all unpushed commits or commits that are not in another branch.

If they're actually managed assemblies, you can use ILMerge. For native DLLs, you'll have a bit more work to do.

You can manipulate the stylesheets and stylesheet rules themselves with javascript

var sheetCount = document.styleSheets.length;
var lastSheet = document.styleSheets[sheetCount-1];
var ruleCount;
if (lastSheet.cssRules) { // Firefox uses 'cssRules'
    ruleCount = lastSheet.cssRules.length;
}
else if (lastSheet.rules) { / /IE uses 'rules'
    ruleCount = lastSheet.rules.length;
}
var newRule = "a:hover { text-decoration: none !important; color: #000 !important; }";
// insert as the last rule in the last sheet so it
// overrides (not overwrites) previous definitions
lastSheet.insertRule(newRule, ruleCount);

Making the attributes !important and making this the very last CSS definition should override any previous definition, unless one is more specifically targeted. You may have to insert more rules in that case.

When dealing with C++ strings (std::string), you're looking for length() or size(). Both should provide you with the same value. However when dealing with C-Style strings, you would use strlen().

#include <iostream>
#include <string.h>

int main(int argc, char **argv)
{
   std::string str = "Hello!";
   const char *otherstr = "Hello!"; // C-Style string
   std::cout << str.size() << std::endl;
   std::cout << str.length() << std::endl;
   std::cout << strlen(otherstr) << std::endl; // C way for string length
   std::cout << strlen(str.c_str()) << std::endl; // convert C++ string to C-string then call strlen
   return 0;
}

Output:

6
6
6
6

You can also put in a new virtual Host entry in the

c:\xampp\apache\conf\httpd-vhosts.conf

like:

<VirtualHost *:80>
  ServerAdmin [email protected]
  DocumentRoot "C:/xampp/htdocs/myproject/web"
  ServerName localhost
  ErrorLog "logs/dummy-host2.example.com-error.log"
  CustomLog "logs/dummy-host2.example.com-access.log" common
</VirtualHost>

Also you can, call by tags names, like this: form_name.input_name.value; So you will have the specific value of determined input in a specific form.

I think your list of reasons is a pretty comprehensive one.

One particularly bad example that I've encountered more than once goes like this:

    try {
      // do stuff
    } catch (Exception e) {
        e.printStackTrace(); // and swallow the exception
    }

The problem with the above code is that the handling consists entirely of the printStackTrace call: the exception isn't really handled properly nor is it allowed to escape.

On the other hand, as a rule I always log the stack trace whenever there's an unexpected exception in my code. Over the years this policy has saved me a lot of debugging time.

Finally, on a lighter note, God's Perfect Exception.

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

Add this in your .htaccess file:

Options -Indexes

If it is not work for any reason, try this within your .htaccess file:

IndexIgnore *

Its workaround.

If you not push to server, you will clone into new folder else washout(delete all files) from your repository folder and clone new.

• Edited -

I got it working with only Route, and did not need RoutePrefix.

For example, in the controller

[HttpPost]
[Route("[action]")]
public IActionResult PostCustomer
([FromBody]CustomerOrder obj)
{
}

and

[HttpPost]
[Route("[action]")]
public IActionResult PostCustomerAndOrder
([FromBody]CustomerOrder obj)
{
}

Then, the function name goes in jquery as either -

options.url = "/api/customer/PostCustomer";

or

options.url = "/api/customer/PostCustomerAndOrder";

Ejecting is not the best option as well as editing something under node_modules. react-app-rewired is not maintained and has the warning:

Guys Please don't make it so complex The simple answer bellow

$date1=date('d_m_y');
$date2='31_12_11';
$date1=str_replace('_', '-', $date1);
$date2=str_replace('_', '-', $date2)

   echo '1 is small ='.strtotime($date1).','.$date1;
else
   echo '2 is small ='.strtotime($date2).','.$date2;

I just have added two more lines with your code

This is untested, but fairly obviously correct:

private int findHeight(Treenode<T> aNode) {
  if (aNode.left == null && aNode.right == null) {
    return 0; // was 1; apparently a node with no children has a height of 0.
  } else if (aNode.left == null) {
    return 1 + findHeight(aNode.right);
  } else if (aNode.right == null) {
    return 1 + findHeight(aNode.left);
  } else {
    return 1 + max(findHeight(aNode.left), findHeight(aNode.right));
  }
}

Often simplifying your code is easier than figuring out why it's off by one. This code is easy to understand: the four possible cases are clearly handled in an obviously correct manner:

• If both the left and right trees are null, return 0, since a single node by definition has a height of 0. (was 1)
• If either the left or right trees (but not both!) are null, return the height of the non-null tree, plus 1 to account for the added height of the current node.
• If neither tree is null, return the height of the taller subtree, again plus one for the current node.

C#:

s1 == null && s2 == null || s1.Length == s2.Length && (s1 + s1).Contains(s2)

What does this thread join code mean?

To quote from the Thread.join() method javadocs:

join() Waits for this thread to die.

There is a thread that is running your example code which is probably the main thread.

1. The main thread creates and starts the t1 and t2 threads. The two threads start running in parallel.
2. The main thread calls t1.join() to wait for the t1 thread to finish.
3. The t1 thread completes and the t1.join() method returns in the main thread. Note that t1 could already have finished before the join() call is made in which case the join() call will return immediately.
4. The main thread calls t2.join() to wait for the t2 thread to finish.
5. The t2 thread completes (or it might have completed before the t1 thread did) and the t2.join() method returns in the main thread.

It is important to understand that the t1 and t2 threads have been running in parallel but the main thread that started them needs to wait for them to finish before it can continue. That's a common pattern. Also, t1 and/or t2 could have finished before the main thread calls join() on them. If so then join() will not wait but will return immediately.

t1.join() means cause t2 to stop until t1 terminates?

No. The main thread that is calling t1.join() will stop running and wait for the t1 thread to finish. The t2 thread is running in parallel and is not affected by t1 or the t1.join() call at all.

In terms of the try/catch, the join() throws InterruptedException meaning that the main thread that is calling join() may itself be interrupted by another thread.

while (true) {

Having the joins in a while loop is a strange pattern. Typically you would do the first join and then the second join handling the InterruptedException appropriately in each case. No need to put them in a loop.

                wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                dialog.setMessage(wordtoSpan);
                dialog.show();

The Basics:

String is an immutable class, it can't be changed. StringBuilder is a mutable class that can be appended to, characters replaced or removed and ultimately converted to a String StringBuffer is the original synchronized version of StringBuilder

You should prefer StringBuilder in all cases where you have only a single thread accessing your object.

The Details:

Also note that StringBuilder/Buffers aren't magic, they just use an Array as a backing object and that Array has to be re-allocated when ever it gets full. Be sure and create your StringBuilder/Buffer objects large enough originally where they don't have to be constantly re-sized every time .append() gets called.

The re-sizing can get very degenerate. It basically re-sizes the backing Array to 2 times its current size every time it needs to be expanded. This can result in large amounts of RAM getting allocated and not used when StringBuilder/Buffer classes start to grow large.

In Java String x = "A" + "B"; uses a StringBuilder behind the scenes. So for simple cases there is no benefit of declaring your own. But if you are building String objects that are large, say less than 4k, then declaring StringBuilder sb = StringBuilder(4096); is much more efficient than concatenation or using the default constructor which is only 16 characters. If your String is going to be less than 10k then initialize it with the constructor to 10k to be safe. But if it is initialize to 10k then you write 1 character more than 10k, it will get re-allocated and copied to a 20k array. So initializing high is better than to low.

In the auto re-size case, at the 17th character the backing Array gets re-allocated and copied to 32 characters, at the 33th character this happens again and you get to re-allocated and copy the Array into 64 characters. You can see how this degenerates to lots of re-allocations and copies which is what you really are trying to avoid using StringBuilder/Buffer in the first place.

This is from the JDK 6 Source code for AbstractStringBuilder

   void expandCapacity(int minimumCapacity) {
    int newCapacity = (value.length + 1) * 2;
        if (newCapacity < 0) {
            newCapacity = Integer.MAX_VALUE;
        } else if (minimumCapacity > newCapacity) {
        newCapacity = minimumCapacity;
    }
        value = Arrays.copyOf(value, newCapacity);
    }

A best practice is to initialize the StringBuilder/Buffer a little bit larger than you think you are going to need if you don't know right off hand how big the String will be but you can guess. One allocation of slightly more memory than you need is going to be better than lots of re-allocations and copies.

Also beware of initializing a StringBuilder/Buffer with a String as that will only allocated the size of the String + 16 characters, which in most cases will just start the degenerate re-allocation and copy cycle that you are trying to avoid. The following is straight from the Java 6 source code.

public StringBuilder(String str) {
    super(str.length() + 16);
    append(str);
    }

If you by chance do end up with an instance of StringBuilder/Buffer that you didn't create and can't control the constructor that is called, there is a way to avoid the degenerate re-allocate and copy behavior. Call .ensureCapacity() with the size you want to ensure your resulting String will fit into.

The Alternatives:

Just as a note, if you are doing really heavy String building and manipulation, there is a much more performance oriented alternative called Ropes.

Another alternative, is to create a StringList implemenation by sub-classing ArrayList<String>, and adding counters to track the number of characters on every .append() and other mutation operations of the list, then override .toString() to create a StringBuilder of the exact size you need and loop through the list and build the output, you can even make that StringBuilder an instance variable and 'cache' the results of .toString() and only have to re-generate it when something changes.

Also don't forget about String.format() when building fixed formatted output, which can be optimized by the compiler as they make it better.

Look at http://ss64.com/nt/if.html for an answer; the command is IF [%1]==[] GOTO NO_ARGUMENT or similar.

Possibly too late to be of benefit now, but is this not the easiest way to do things?

These instructions work for OSX High Sierra and avoid running gdb as root (yuck!). I recently updated from OSX 10.13.2 to 10.3.3. I think this is when gdb 8.0.1 (installed w/ homebrew) started failing for me.

I had difficulty with other people's instructions. After different instructions, everything was a mess. So I started a fresh. I more or less followed these instructions.

Clean the mess :

1. brew uninstall --force gdb # This deletes _all_ versions of gdb on the machine
2. In Applications -> Utilities -> Keychain Access, I deleted all previous gdb certificates and keys (be sure you know what you're doing here!). It's unclear if this is necessary, but since I'd buggered up trying to create those certificates and keys using other instructions I eliminated them anyways. I had keys and certificates in both login and system.

Now reinstall gdb.

3. brew install gdb
4. Within Keychain Access, go to menu Keychain Access-> Certificate Assistant -> Create a Certificate
5. Check "Let me override defaults" and set

Name : gdb-cert
Identity Type: Self Signed Root
Certificate Type : Code Signing

[X] Let me override defaults

6. On 1st Certificate Information page:

Serial Number : 1
Validity Period (days): 3650

7. On 2nd Certificate Information page, I left all fields blank except those already filled in.

8. On Key Pair Information page, I left the defaults

Key Size : 2048
Algorithm : RSA

9. On Key Usage Extension page, I left the defaults checked.

[X] Include Key Usage Extension
[X] This extension is critical
Capabilities:
[X] Signature

10. On Extended Key Usage Extension page, I left the defaults checked.

[X] Include Extended Key Usage Extension
[X] This extension is critical
Capabilities:
[X] Code Signing

11. On Basic Constraints Extension Page, nothing was checked (default).

12. On Subject Alternate Name Extension page, I left the default checked and didn't add anything else.

[X] Include Subject Alternate Name Extension

13. On Specify a Location for the certificate page, I set

Keychain: System

14. I clicked Create and was prompted for my password.

15. Back in the Keychain Access app, I went to System and right clicked on gdb-cert and under dropdown menu Trust, I changed all the fields to Always Trust.

16. Rebooted computer.

17. At the Terminal, I ran codesign -s gdb-cert /usr/local/bin/gdb. I entered my password when prompted.

18. At the Terminal, I ran echo "set startup-with-shell off" >> ~/.gdbinit

19. I ran gdb myprogram and then start within the gdb console. Here, I believe, it prompted for me for my password. After that, all subsequent runs, it did not prompt for my password.

Interpreted languages like Python and JavaScript benefit greatly from linting, as these languages don’t have a compiling phase to display errors before execution.

Linters are also useful for code formatting and/or adhering to language specific best practices.

Lately I have been using ESLint for JS/React and will occasionally use it with an airbnb-config file.

import java.io.*;
public class Upch2
{
   BufferedReader br= new BufferedReader( new InputStreamReader(System.in));
   public void main()throws IOException
    { 
        System.out.println("Pl. Enter A Line");
        String s=br.readLine();
        String s1=" ";
        s=" "+s;
        int len=s.length();
        s= s.toLowerCase();
        for(int j=1;j<len;j++)
         {
           char  ch=s.charAt(j);

           if(s.charAt(j-1)!=' ')
           {
             ch=Character.toLowerCase((s.charAt(j)));
           }
           else
           {
             ch=Character.toUpperCase((s.charAt(j)));
            }
            s1=s1+ch;
          }
     System.out.println(" "+s1);
  }
}

In C range for __int32 is –2147483648 to 2147483647. See here for full ranges.

unsigned short 0 to 65535
signed short –32768 to 32767
unsigned long 0 to 4294967295
signed long –2147483648 to 2147483647

There are no guarantees that an 'int' will be 32 bits, if you want to use variables of a specific size, particularly when writing code that involves bit manipulations, you should use the 'Standard Integer Types'.

In Java

The int data type is a 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive).

Try SELECT * FROM Profiles WHERE date(DateReg)=$date where $date is in yyyy-mm-dd

Alternatively SELECT * FROM Profiles WHERE left(DateReg,10)=$date

Registering DLL for Fundsite

Outdated or missing comdlg32.ocx runtime library can be the problem of causing this error. Make sure comdlg32.ocx file is not corrupted otherwise Download the File comdlg32.ocx (~60 Kb Zip).

Download the file and extract the comdlg32.ocx to your the Windows\System32 folder or Windows\SysWOW64. In my case i started with Windows\System32 but it didn’t work at my end, so I again saved in Windows\SysWOW64.

Type following command from Start, Run dialog:“c:\windows>System32\regsvr32 Comdlg32.ocx “ or “c:\windows>SysWOW64\regsvr32 Comdlg32.ocx ”

Now Comdlg.ocx File is register and next step is to register the DLL

1. Copy the Fundsite.Text.Encoding. dll into .Net Framework folder for 64bit on below path C:\Windows\Microsoft.NET\Framework64\v2.0.50727

2. Then on command prompt and go to directory C:\Windows\Microsoft.NET\Framework64\v2.0.50727 and then run the following command as shown below.

This will register the dll successfully.

C:\Windows\Microsoft.net\framework64\v2.0.50727>regasm "Dll Name".dll

I've simply managed to get dropzone and other plugin to work with this fix (angularjs + php backend)

 header('Access-Control-Allow-Origin: *'); 
    header("Access-Control-Allow-Credentials: true");
    header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
    header('Access-Control-Max-Age: 1000');
    header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token , Authorization');

add this in your upload.php or where you would send your request (for example if you have upload.html and you need to attach the files to upload.php, then copy and paste these 4 lines). Also if you're using CORS plugins/addons in chrome/mozilla be sure to toggle them more than one time,in order for CORS to be enabled

I found this useful to read from a specific column and row:

FileStream stream = File.Open(@"C:\Users\Desktop\ExcelDataReader.xlsx", FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
DataSet result = excelReader.AsDataSet();
excelReader.IsFirstRowAsColumnNames = true;         
DataTable dt = result.Tables[0];
string text = dt.Rows[1][0].ToString();

Do you mean this one?

You should put your processing into the class constructor or an OnInit hook method.

ints are value types; they can never be null. Instead, if the parsing failed, parseInt will throw a NumberFormatException that you need to catch.

Use selectionStart/selectionEnd properties of the input element (works for <textarea> as well)

function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        myField.focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    //MOZILLA and others
    else if (myField.selectionStart || myField.selectionStart == '0') {
        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        myField.value = myField.value.substring(0, startPos)
            + myValue
            + myField.value.substring(endPos, myField.value.length);
    } else {
        myField.value += myValue;
    }
}

Your syntax is incorrect, you should either specify a hash:

hash = {abc: true, def: true, ghi: true};

Or an array:

arr = ['abc','def','ghi'];

You can effectively remove an item from a hash by simply setting it to null:

hash['def'] = null;
hash.def = null;

Or removing it entirely:

delete hash.def;

To remove an item from an array you have to iterate through each item and find the one you want (there may be duplicates). You could use array searching and splicing methods:

arr.splice(arr.indexOf("def"), 1);

This finds the first index of "def" and then removes it from the array with splice. However I would recommend .filter() because it gives you more control:

arr.filter(function(item) { return item !== 'def'; });

This will create a new array with only elements that are not 'def'.

It is important to note that arr.filter() will return a new array, while arr.splice will modify the original array and return the removed elements. These can both be useful, depending on what you want to do with the items.

Google had changed their policy so the old way for getting the Google profile image will not work now, which was

https://plus.google.com/s2/photos/profile/(user_id)?sz=150

New Way for doing this is

Request URL

https://www.googleapis.com/plus/v1/people/115950284...320?fields=image&key={YOUR_API_KEY}

That will give the Google profile image url in json format as given below

Response :

{
    "image": 
    {
         "url": "https://lh3.googleusercontent.com/-OkM...AANA/ltpH4BFZ2as/photo.jpg?sz=50"
    }
}

More parameters can be found to send with URL which you may need from here

For more detail you can also check the given question where I have answered for same type of problem How to get user image through user id in Google plus?

Quoting the spec

15.4 Array Objects

Array objects give special treatment to a certain class of property names. A property name P (in the form of a String value) is an array index if and only if ToString(ToUint32(P)) is equal to P and ToUint32(P) is not equal to 2^32-1. A property whose property name is an array index is also called an element. Every Array object has a length property whose value is always a nonnegative integer less than 2^32. The value of the length property is numerically greater than the name of every property whose name is an array index; whenever a property of an Array object is created or changed, other properties are adjusted as necessary to maintain this invariant. Specifically, whenever a property is added whose name is an array index, the length property is changed, if necessary, to be one more than the numeric value of that array index; and whenever the length property is changed, every property whose name is an array index whose value is not smaller than the new length is automatically deleted. This constraint applies only to own properties of an Array object and is unaffected by length or array index properties that may be inherited from its prototypes.

And here's a table for typeof

To add some background, there are two data types in JavaScript:

1. Primitive Data types - This includes null, undefined, string, boolean, number and object.
2. Derived data types/Special Objects - These include functions, arrays and regular expressions. And yes, these are all derived from "Object" in JavaScript.

An object in JavaScript is similar in structure to the associative array/dictionary seen in most object oriented languages - i.e., it has a set of key-value pairs.

An array can be considered to be an object with the following properties/keys:

1. Length - This can be 0 or above (non-negative).
2. The array indices. By this, I mean "0", "1", "2", etc are all properties of array object.

Hope this helped shed more light on why typeof Array returns an object. Cheers!

The solutions turned out to be very simple.

1. Open text edit

2. Write the command, save as .bat.

3. Double click the file created and the command automatically starts running in command-prompt.

I fixed this error by inserting these lines of code:

<dependency>
  <groupId>junit</groupId>     <!-- NOT org.junit here -->
  <artifactId>junit-dep</artifactId>
  <version>4.8.2</version>
  <scope>test</scope>
</dependency>

into <dependencies> node.

lst = [('candy','30','100'), ('apple','10','200'), ('baby','20','300')]
lst.sort(key=lambda x:x[1])
print(lst)

It will print as following:

[('apple', '10', '200'), ('baby', '20', '300'), ('candy', '30', '100')]

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

http://jsfiddle.net/4NB2N/7/

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

I was trying to put together some JavaScript to validate a domain name (ex. google.com) and if it validates enable a submit button. I thought that I would share my code for those who are looking to accomplish something similar. It expects a domain without any http:// or www. value. The script uses a stripped down regular expression from above for domain matching, which isn't strict about fake TLD.

http://jsfiddle.net/nMVDS/1/

$(function () {
  $('#whitelist_add').keyup(function () {
    if ($(this).val() == '') { //Check to see if there is any text entered
        //If there is no text within the input, disable the button
        $('.whitelistCheck').attr('disabled', 'disabled');
    } else {
        // Domain name regular expression
        var regex = new RegExp("^([0-9A-Za-z-\\.@:%_\+~#=]+)+((\\.[a-zA-Z]{2,3})+)(/(.)*)?(\\?(.)*)?");
        if (regex.test($(this).val())) {
            // Domain looks OK
            //alert("Successful match");
            $('.whitelistCheck').removeAttr('disabled');
        } else {
            // Domain is NOT OK
            //alert("No match");
            $('.whitelistCheck').attr('disabled', 'disabled');
        }
    }
  });
});

@TonyO'Hagan is comprehrensive shelljs answer, but, I would like to highlight the synchronous version of his answer:

for me this useful dummy guide - Sorting in Generic List - worked. it helps you to understand 4 ways(overloads) to do this job with very complete and clear explanations and simple examples

• List.Sort ()
• List.Sort (Generic Comparison)
• List.Sort (Generic IComparer)
• List.Sort (Int32, Int32, Generic IComparer)

If it's worth adding another file / dependency to your project, I've just written a tiny little class that extends datetime.time with the ability to do arithmetic. When you go past midnight, it wraps around zero. Now, "What time will it be, 24 hours from now" has a lot of corner cases, including daylight savings time, leap seconds, historical timezone changes, and so on. But sometimes you really do need the simple case, and that's what this will do.

Your example would be written:

>>> import datetime
>>> import nptime
>>> nptime.nptime(11, 34, 59) + datetime.timedelta(0, 3)
nptime(11, 35, 2)

nptime inherits from datetime.time, so any of those methods should be usable, too.

It's available from PyPi as nptime ("non-pedantic time"), or on GitHub: https://github.com/tgs/nptime

Microsoft listed the following methods for getting the a View definition: http://technet.microsoft.com/en-us/library/ms175067.aspx

You can use following git command to clone with custom directory name

git clone <git_repo_url> <your_custom_directory_name>

Note: You don't need to create your custom directory because it will create automatically

As dowski suggested, you could use WMI to get printer properties. The following code displays all properties for a given printer name. Among them you will find: PrinterStatus, Comment, Location, DriverName, PortName, etc.

using System.Management;

...

string printerName = "YourPrinterName";
string query = string.Format("SELECT * from Win32_Printer WHERE Name LIKE '%{0}'", printerName);

using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
using (ManagementObjectCollection coll = searcher.Get())
{
    try
    {
        foreach (ManagementObject printer in coll)
        {
            foreach (PropertyData property in printer.Properties)
            {
                Console.WriteLine(string.Format("{0}: {1}", property.Name, property.Value));
            }
        }
    }
    catch (ManagementException ex)
    {
        Console.WriteLine(ex.Message);
    }
}

In the hexadecimal it can't get a negative value. So it shows it like ffffffff.

The advantage to using the unsigned version (when you know the values contained will be non-negative) is that sometimes the computer will spot errors for you (the program will "crash" when a negative value is assigned to the variable).

You can get the scrollbar position using document.documentElement.scrollTop. And then it is simply matter of comparing it to the previous position.

You can try the code in the following snippet, it covers your needs using plain javascript. (run the code snippet and click full page link to trigger the alert that the div is resized if you want to test it.).

Based on the fact that this is a setInterval of 100 milliseconds, i would dare to say that my PC did not find it too much CPU hungry. (0.1% of CPU was used as total for all opened tabs in Chrome at the time tested.). But then again this is for just one div, if you would like to do this for a large amount of elements then yes it could be very CPU hungry.

You could always use a click event to stop the div-resize sniffing anyway.

var width = 0; 
var interval = setInterval(function(){
if(width <= 0){
width = document.getElementById("test_div").clientWidth;
} 
if(document.getElementById("test_div").clientWidth!==width) {   
  alert('resized div');
  width = document.getElementById("test_div").clientWidth;
}    

}, 100);

<div id="test_div" style="width: 100%; min-height: 30px; border: 1px dashed pink;">
        <input type="button" value="button 1" />
        <input type="button" value="button 2" />
        <input type="button" value="button 3" />
</div>

UPDATE

var width = 0; 
function myInterval() {
var interval = setInterval(function(){
if(width <= 0){
width = document.getElementById("test_div").clientWidth;

myInterval();
alert("started div-resize sniffing");

Lines 45-47:

?>

<?php

That's sending a couple of newlines as output, so the headers are already dispatched. Just remove those 3 lines (it's all one big PHP block after all, no need to end PHP parsing and then start it again), as well as the similar block on lines 60-62, and it'll work.

Notice that the error message you got actually gives you a lot of information to help you find this yourself:

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\speedycms\deleteclient.php:47) in C:\xampp\htdocs\speedycms\deleteclient.php on line 106

The two bolded sections tell you where the item is that sent output before the headers (line 47) and where the item is that was trying to send a header after output (line 106).
