Yet another way of doing it:

using (HttpClient httpClient = new HttpClient())
using (MultipartFormDataContent form = new MultipartFormDataContent())
{
    form.Add(new StringContent(param1), "param1");
    form.Add(new StringContent(param2), "param2");
    using (HttpResponseMessage response = await httpClient.PostAsync(url, form))
    {
        response.EnsureSuccessStatusCode();
        string res = await response.Content.ReadAsStringAsync();
        return res;
    }
}

This way you can easily post a stream.

Request and Superagent are pretty good libraries to use.

note: request is deprecated, use at your risk!

Using request:

var request=require('request');

request.get('https://someplace',options,function(err,res,body){
  if(err) //TODO: handle err
  if(res.statusCode === 200 ) //etc
  //TODO Do something with response
});

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

You can also just right click on the page in the browser and select "Inspect Element" to bring up the developer tools.

https://developer.chrome.com/devtools

Set a cookie value on the page, and then read it back server side.

You won't be able to set a specific header, but the value will be accessible in the headers section and not the content body.

I encountered this error, and the fix appears to be turning off SNI, which Python 2.7 does not support:

http://bugs.python.org/issue5639

urllib3 on python 2.7 SNI error on Google App Engine

If your server is running behind a proxy server, make sure your proxy header is set:

proxy_set_header X-Forwarded-Proto  $scheme;

Then to get the right scheme & url you can use springframework's classes:

public String getUrl(HttpServletRequest request) {
    HttpRequest httpRequest = new ServletServerHttpRequest(request);
    UriComponents uriComponents = UriComponentsBuilder.fromHttpRequest(httpRequest).build();

    String scheme = uriComponents.getScheme();             // http / https
    String serverName = request.getServerName();     // hostname.com
    int serverPort = request.getServerPort();        // 80
    String contextPath = request.getContextPath();   // /app

    // Reconstruct original requesting URL
    StringBuilder url = new StringBuilder();
    url.append(scheme).append("://");
    url.append(serverName);

    if (serverPort != 80 && serverPort != 443) {
        url.append(":").append(serverPort);
    }
    url.append(contextPath);
    return url.toString();
}

Run all Collection in a folder in parallel:

'use strict';

global.Promise = require('bluebird');
const path = require('path');
const newman =  Promise.promisifyAll(require('newman'));
const fs = Promise.promisifyAll(require('fs'));
const environment = 'postman_environment.json';
const FOLDER = path.join(__dirname, 'Collections_Folder');


let files = fs.readdirSync(FOLDER);
files = files.map(file=> path.join(FOLDER, file))
console.log(files);

Promise.map(files, file => {

    return newman.runAsync({
    collection: file, // your collection
    environment: path.join(__dirname, environment), //your env
    reporters: ['cli']
    });

}, {
   concurrency: 2
});

I'm using following code from Application_Start

String baseUrl = Path.GetDirectoryName(HttpContext.Current.Request.Url.OriginalString);

I would aim at covering a subset of possible "Content-type" values, you question seems to focus on identifying known content types.

@Jeroen RFC 1341 reference is great, but for an fairly exhaustive list IANA keeps a web page of officially registered media types here.

For Logging your request and response you need an interceptor and also for setting the header you need an interceptor, Here's the solution for adding both the interceptor at once using retrofit 2.1

 public OkHttpClient getHeader(final String authorizationValue ) {
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient okClient = new OkHttpClient.Builder()
                .addInterceptor(interceptor)
                .addNetworkInterceptor(
                        new Interceptor() {
                            @Override
                            public Response intercept(Interceptor.Chain chain) throws IOException {
                                Request request = null;
                                if (authorizationValue != null) {
                                    Log.d("--Authorization-- ", authorizationValue);

                                    Request original = chain.request();
                                    // Request customization: add request headers
                                    Request.Builder requestBuilder = original.newBuilder()
                                            .addHeader("Authorization", authorizationValue);

                                    request = requestBuilder.build();
                                }
                                return chain.proceed(request);
                            }
                        })
                .build();
        return okClient;

    }

Now in your retrofit object add this header in the client

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(url)
                .client(getHeader(authorizationValue))
                .addConverterFactory(GsonConverterFactory.create())
                .build();

I had the same error when I imported web requests from fiddler captured sessions to Visual Studio webtests. Some POST requests did not have a StringHttpBody tag. I added an empty one to them and the error was gone. Add this after the Headers tag:

    <StringHttpBody ContentType="" InsertByteOrderMark="False">
  </StringHttpBody>

Swift 4 and above

@IBAction func submitAction(sender: UIButton) {

    //declare parameter as a dictionary which contains string as key and value combination. considering inputs are valid

    let parameters = ["id": 13, "name": "jack"]

    //create the url with URL
    let url = URL(string: "www.thisismylink.com/postName.php")! //change the url

    //create the session object
    let session = URLSession.shared

    //now create the URLRequest object using the url object
    var request = URLRequest(url: url)
    request.httpMethod = "POST" //set http method as POST

    do {
        request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body
    } catch let error {
        print(error.localizedDescription)
    }

    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    //create dataTask using the session object to send data to the server
    let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in

        guard error == nil else {
            return
        }

        guard let data = data else {
            return
        }

        do {
            //create json object from data
            if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
                print(json)
                // handle json...
            }
        } catch let error {
            print(error.localizedDescription)
        }
    })
    task.resume()
}

It has to be made clear the HTTP protocol is synchronous and this has nothing to do with the programming language. Client sends a request and gets a synchronous response.

If you want to an asynchronous behavior over HTTP, this has to be built over HTTP (I don't know anything about ActionScript but I suppose that this is what the ActionScript does too). There are many libraries that could give you such functionality (e.g. Jersey SSE). Note that they do somehow define dependencies between the client and the server as they do have to agree on the exact non standard communication method above HTTP.

If you cannot control both the client and the server or if you don't want to have dependencies between them, the most common approach of implementing asynchronous (e.g. event based) communication over HTTP is using the webhooks approach (you can check this for an example implementation in java).

Hope I helped!

It is also worth mentioning that localStorage cannot be used when users browse in "private" mode in some versions of mobile Safari.

Quoted from MDN (https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage):

Note: Starting with iOS 5.1, Safari Mobile stores localStorage data in the cache folder, which is subject to occasional clean up, at the behest of the OS, typically if space is short. Safari Mobile's Private Browsing mode also prevents writing to localStorage entirely.

java.net.URLEncoder.encode(finalPartOfString, "utf-8");

This will URL-encode the string.

finalPartOfString is the part after the last slash - in your case, the name of the song, as it seems.

Initially I was misled by this article which favours HttpClient.

Later I have been realized that HttpURLConnection is going to stay from this article

As per the Google blog:

Apache HTTP client has fewer bugs on Eclair and Froyo. It is the best choice for these releases. For Gingerbread , HttpURLConnection is the best choice. Its simple API and small size makes it great fit for Android.

Transparent compression and response caching reduce network use, improve speed and save battery. New applications should use HttpURLConnection; it is where we will be spending our energy going forward.

After reading this article and some other stack over flow questions, I am convinced that HttpURLConnection is going to stay for longer durations.

Some of the SE questions favouring HttpURLConnections:

On Android, make a POST request with URL Encoded Form data without using UrlEncodedFormEntity

HttpPost works in Java project, not in Android

For ASP.NET you can get the header directly from parameter in controller method using this simple library/package. It provides a [FromHeader] attribute just like you have in ASP.NET Core :). For example:

    ...
    using RazHeaderAttribute.Attributes;

    [Route("api/{controller}")]
    public class RandomController : ApiController 
    {
        ...
        // GET api/random
        [HttpGet]
        public IEnumerable<string> Get([FromHeader("pages")] int page, [FromHeader] string rows)
        {
            // Print in the debug window to be sure our bound stuff are passed :)
            Debug.WriteLine($"Rows {rows}, Page {page}");
            ...
        }
    }

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);
});

I know that is a old question, but...

You can also use this in your class:

@Autowired
private HttpServletRequest context;

And this will provide the current instance of HttpServletRequest for you use on your method.

By design, getRequestURL() gives you the full URL, missing only the query string.

In HttpServletRequest, you can get individual parts of the URI using the methods below:

// Example: http://myhost:8080/people?lastname=Fox&age=30

String uri = request.getScheme() + "://" +   // "http" + "://
             request.getServerName() +       // "myhost"
             ":" +                           // ":"
             request.getServerPort() +       // "8080"
             request.getRequestURI() +       // "/people"
             "?" +                           // "?"
             request.getQueryString();       // "lastname=Fox&age=30"

• .getScheme() will give you "https" if it was a https://domain request.
• .getServerName() gives domain on http(s)://domain.
• .getServerPort() will give you the port.

Use the snippet below:

String uri = request.getScheme() + "://" +
             request.getServerName() + 
             ("http".equals(request.getScheme()) && request.getServerPort() == 80 || "https".equals(request.getScheme()) && request.getServerPort() == 443 ? "" : ":" + request.getServerPort() ) +
             request.getRequestURI() +
            (request.getQueryString() != null ? "?" + request.getQueryString() : "");

This snippet above will get the full URI, hiding the port if the default one was used, and not adding the "?" and the query string if the latter was not provided.

Proxied requests

Note, that if your request passes through a proxy, you need to look at the X-Forwarded-Proto header since the scheme might be altered:

request.getHeader("X-Forwarded-Proto")

Also, a common header is X-Forwarded-For, which show the original request IP instead of the proxys IP.

request.getHeader("X-Forwarded-For")

If you are responsible for the configuration of the proxy/load balancer yourself, you need to ensure that these headers are set upon forwarding.

Python's standard library has json and urllib2 modules.

import json
import urllib2

data = json.load(urllib2.urlopen('http://someurl/path/to/json'))

As mentioned in multiple answers above you can import the cURL in POSTMAN directly. But if URL is authorized (or is not working for some reason) ill suggest you can manually add all the data points as JSON in your postman body. take the API URL from the cURL.

for the Authorization part- just add an Authorization key and base 64 encoded string as value.

example:

curl -u rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a \ https://api.razorpay.com/v1/orders -X POST \ --data "amount=50000" \ --data "currency=INR" \ --data "receipt=Receipt #20" \ --data "payment_capture=1" https://api.razorpay.com/v1/orders

{ "amount": "5000", "currency": "INR", "receipt": "Receipt #20", "payment_capture": "1" }

Headers: Authorization:Basic cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J where "cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J" is the encoded form of "rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a"`

small tip: for encoding, you can easily go to your chrome console (right-click => inspect) and type : btoa("string you want to encode") ( or use postman basic authorization)

You can use embeddedRest library. It is lightweight header-only library. So it is easy to include it to your project and it does not require compilation cause there no .cpp files in it.

Request example from readme.md from repo:

#include "UrlRequest.hpp"

//...

UrlRequest request;
request.host("api.vk.com");
const auto countryId = 1;
const auto count = 1000;
request.uri("/method/database.getCities",{
    { "lang", "ru" },
    { "country_id", countryId },
    { "count", count },
    { "need_all", "1" },
});
request.addHeader("Content-Type: application/json");
auto response = std::move(request.perform());
if (response.statusCode() == 200) {
  cout << "status code = " << response.statusCode() << ", body = *" << response.body() << "*" << endl;
}else{
  cout << "status code = " << response.statusCode() << ", description = " << response.statusDescription() << endl;
}

In my opinion, caisah's answer misses an important part of your question, namely dealing with the server being offline.

Still, using requests is my favorite option, albeit as such:

import requests

try:
    requests.get(url)
except requests.exceptions.ConnectionError:
    print(f"URL {url} not reachable")

params is for GET-style URL parameters, data is for POST-style body information. It is perfectly legal to provide both types of information in a request, and your request does so too, but you encoded the URL parameters into the URL already.

Your raw post contains JSON data though. requests can handle JSON encoding for you, and it'll set the correct Content-Type header too; all you need to do is pass in the Python object to be encoded as JSON into the json keyword argument.

You could split out the URL parameters as well:

params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}

then post your data with:

import requests

url = 'http://192.168.3.45:8080/api/v2/event/log'

data = {"eventType": "AAS_PORTAL_START", "data": {"uid": "hfe3hf45huf33545", "aid": "1", "vid": "1"}}
params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}

requests.post(url, params=params, json=data)

The json keyword is new in requests version 2.4.2; if you still have to use an older version, encode the JSON manually using the json module and post the encoded result as the data key; you will have to explicitly set the Content-Type header in that case:

import requests
import json

headers = {'content-type': 'application/json'}
url = 'http://192.168.3.45:8080/api/v2/event/log'

data = {"eventType": "AAS_PORTAL_START", "data": {"uid": "hfe3hf45huf33545", "aid": "1", "vid": "1"}}
params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}

requests.post(url, params=params, data=json.dumps(data), headers=headers)

You can use httpx for that.

import httpx

async def get_async(url):
    async with httpx.AsyncClient() as client:
        return await client.get(url)

urls = ["http://google.com", "http://wikipedia.org"]

# Note that you need an async context to use `await`.
await asyncio.gather(*map(get_async, urls))

if you want a functional syntax, the gamla lib wraps this into get_async.

Then you can do

await gamla.map(gamla.get_async(10))(["http://google.com", "http://wikipedia.org"])

The 10 is the timeout in seconds.

(disclaimer: I am its author)

request.META.get('HTTP_AUTHORIZATION') /python3.6/site-packages/rest_framework/authentication.py

you can get that from this file though...

You should be able to use jQuery.ajax :

Load a remote page using an HTTP request.

And you can specify which method should be used, with the type option :

The type of request to make ("POST" or "GET"), default is "GET".
Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers.

Since nobody provided a wire capture, here's one.
Server Name (the domain part of the URL) is presented in the ClientHello packet, in plain text.

The following shows a browser request to:
https://i.stack.imgur.com/path/?some=parameters&go=here

See this answer for more on TLS version fields (there are 3 of them - not versions, fields that each contain a version number!)

From https://www.ietf.org/rfc/rfc3546.txt:

3.1. Server Name Indication

[TLS] does not provide a mechanism for a client to tell a server the name of the server it is contacting. It may be desirable for clients to provide this information to facilitate secure connections to servers that host multiple 'virtual' servers at a single underlying network address.

In order to provide the server name, clients MAY include an extension of type "server_name" in the (extended) client hello.

In short:

• FQDN (the domain part of the URL) MAY be transmitted in clear inside the ClientHello packet if SNI extension is used

• The rest of the URL (/path/?some=parameters&go=here) has no business being inside ClientHello since the request URL is a HTTP thing (OSI Layer 7), therefore it will never show up in a TLS handshake (Layer 4 or 5). That will come later on in a GET /path/?some=parameters&go=here HTTP/1.1 HTTP request, AFTER the secure TLS channel is established.

EXECUTIVE SUMMARY

Domain name MAY be transmitted in clear (if SNI extension is used in the TLS handshake) but URL (path and parameters) is always encrypted.

MARCH 2019 UPDATE

Thank you carlin.scott for bringing this one up.

The payload in the SNI extension can now be encrypted via this draft RFC proposal. This capability only exists in TLS 1.3 (as an option and it's up to both ends to implement it) and there is no backwards compatibility with TLS 1.2 and below.

CloudFlare is doing it and you can read more about the internals here — If the chicken must come before the egg, where do you put the chicken?

In practice this means that instead of transmitting the FQDN in plain text (like the Wireshark capture shows), it is now encrypted.

NOTE: This addresses the privacy aspect more than the security one since a reverse DNS lookup MAY reveal the intended destination host anyway.

SEPTEMBER 2020 UPDATE

There's now a draft RFC for encrypting the entire Client Hello message, not just the SNI part: https://datatracker.ietf.org/doc/draft-ietf-tls-esni/?include_text=1

At the time of writing this browser support is VERY limited.

Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).

I would rather set max listeners number in your own code:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

It is not possible to get HTTP Response code by using Selenium WebDriver directly. The code can be got by using Java code and that can be used in Selenium WebDriver.

To get HTTP Response code by java:

public static int getResponseCode(String urlString) throws MalformedURLException, IOException{
    URL url = new URL(urlString);
    HttpURLConnection huc = (HttpURLConnection)url.openConnection();
    huc.setRequestMethod("GET");
    huc.connect();
    return huc.getResponseCode();
}

Now you can write your Selenium WebDriver code as below:

private static int statusCode;
public static void main(String... args) throws IOException{
    WebDriver driver = new FirefoxDriver();
    driver.manage().window().maximize();
    driver.get("https://www.google.com/");
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

    List<WebElement> links = driver.findElements(By.tagName("a"));
    for(int i = 0; i < links.size(); i++){
        if(!(links.get(i).getAttribute("href") == null) && !(links.get(i).getAttribute("href").equals(""))){
            if(links.get(i).getAttribute("href").contains("http")){
                statusCode= getResponseCode(links.get(i).getAttribute("href").trim());
                if(statusCode == 403){
                    System.out.println("HTTP 403 Forbidden # " + i + " " + links.get(i).getAttribute("href"));
                }
            }
        }   
    }   
}

My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).

public class getUserProfile extends AsyncTask<Void, String, JSONArray> {
    JSONArray array;
    @Override
    protected JSONArray doInBackground(Void... params) {

        try {
            commonurl cu = new commonurl();
            String u = cu.geturl("tempshowusermain.php");
            URL url =new URL(u);
          //  URL url = new URL("http://192.168.225.35/jabber/tempshowusermain.php");
            HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
            httpURLConnection.setRequestMethod("POST");
            httpURLConnection.setRequestProperty("Content-Type", "application/json");
            httpURLConnection.setRequestProperty("Accept", "application/json");
            httpURLConnection.setDoOutput(true);
            httpURLConnection.setRequestProperty("Connection", "Keep-Alive");
            httpURLConnection.setDoInput(true);
            httpURLConnection.connect();

            JSONObject jsonObject=new JSONObject();
            jsonObject.put("lid",lid);


            DataOutputStream outputStream = new DataOutputStream(httpURLConnection.getOutputStream());
            outputStream.write(jsonObject.toString().getBytes("UTF-8"));

            int code = httpURLConnection.getResponseCode();
            if (code == 200) {
                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream()));

                StringBuffer stringBuffer = new StringBuffer();

I faced this issue on Node 10.X version. below is my working code.

const https = require('https');

exports.handler = (event,context,callback) => {
    let body='';
    let jsonObject = JSON.stringify(event);

    // the post options
    var optionspost = {
      host: 'example.com', 
      path: '/api/mypath',
      method: 'POST',
      headers: {
      'Content-Type': 'application/json',
      'Authorization': 'blah blah',
    }
    };

    let reqPost =  https.request(optionspost, function(res) {
        console.log("statusCode: ", res.statusCode);
        res.on('data', function (chunk) {
            body += chunk;
        });
        res.on('end', function () {
           console.log("Result", body.toString());
           context.succeed("Sucess")
        });
        res.on('error', function () {
          console.log("Result Error", body.toString());
          context.done(null, 'FAILURE');
        });
    });
    reqPost.write(jsonObject);
    reqPost.end();
};

The only way would be for you to consume the entire input stream yourself in the filter, take what you want from it, and then create a new InputStream for the content you read, and put that InputStream in to a ServletRequestWrapper (or HttpServletRequestWrapper).

The downside is you'll have to parse the payload yourself, the standard doesn't make that capability available to you.

Addenda --

As I said, you need to look at HttpServletRequestWrapper.

In a filter, you continue along by calling FilterChain.doFilter(request, response).

For trivial filters, the request and response are the same as the ones passed in to the filter. That doesn't have to be the case. You can replace those with your own requests and/or responses.

HttpServletRequestWrapper is specifically designed to facilitate this. You pass it the original request, and then you can intercept all of the calls. You create your own subclass of this, and replace the getInputStream method with one of your own. You can't change the input stream of the original request, so instead you have this wrapper and return your own input stream.

The simplest case is to consume the original requests input stream in to a byte buffer, do whatever magic you want on it, then create a new ByteArrayInputStream from that buffer. This is what is returned in your wrapper, which is passed to the FilterChain.doFilter method.

You'll need to subclass ServletInputStream and make another wrapper for your ByteArrayInputStream, but that's not a big deal either.

Everyone so far has been wrong, because BeginGetResponse() does some work on the current thread. From the documentation:

The BeginGetResponse method requires some synchronous setup tasks to complete (DNS resolution, proxy detection, and TCP socket connection, for example) before this method becomes asynchronous. As a result, this method should never be called on a user interface (UI) thread because it might take considerable time (up to several minutes depending on network settings) to complete the initial synchronous setup tasks before an exception for an error is thrown or the method succeeds.

So to do this right:

void DoWithResponse(HttpWebRequest request, Action<HttpWebResponse> responseAction)
{
    Action wrapperAction = () =>
    {
        request.BeginGetResponse(new AsyncCallback((iar) =>
        {
            var response = (HttpWebResponse)((HttpWebRequest)iar.AsyncState).EndGetResponse(iar);
            responseAction(response);
        }), request);
    };
    wrapperAction.BeginInvoke(new AsyncCallback((iar) =>
    {
        var action = (Action)iar.AsyncState;
        action.EndInvoke(iar);
    }), wrapperAction);
}

You can then do what you need to with the response. For example:

HttpWebRequest request;
// init your request...then:
DoWithResponse(request, (response) => {
    var body = new StreamReader(response.GetResponseStream()).ReadToEnd();
    Console.Write(body);
});

I found that the above answer caused me an exception when I tried to instantiate the parser. I found the following code that resolved this at http://docstore.mik.ua/orelly/xml/sax2/ch03_02.htm.

import org.xml.sax.*;
import javax.xml.parsers.*;

XMLReader        parser;

try {
    SAXParserFactory factory;

    factory = SAXParserFactory.newInstance ();
    factory.setNamespaceAware (true);
    parser = factory.newSAXParser ().getXMLReader ();
    // success!

} catch (FactoryConfigurationError err) {
    System.err.println ("can't create JAXP SAXParserFactory, "
    + err.getMessage ());
} catch (ParserConfigurationException err) {
    System.err.println ("can't create XMLReader with namespaces, "
    + err.getMessage ());
} catch (SAXException err) {
    System.err.println ("Hmm, SAXException, " + err.getMessage ());
}

Too much code for this task, checkout this library https://github.com/kodart/Httpzoid Is uses GSON internally and provides API that works with objects. All JSON details are hidden.

Http http = HttpFactory.create(context);
http.get("http://example.com/users")
    .handler(new ResponseHandler<User[]>() {
        @Override
        public void success(User[] users, HttpResponse response) {
        }
    }).execute();

If you want to extend the amount of time permitted for an ASP.NET script to execute then increase the Server.ScriptTimeout value. The default is 90 seconds for .NET 1.x and 110 seconds for .NET 2.0 and later.

For example:

// Increase script timeout for current page to five minutes
Server.ScriptTimeout = 300;

This value can also be configured in your web.config file in the httpRuntime configuration element:

<!-- Increase script timeout to five minutes -->
<httpRuntime executionTimeout="300" 
  ... other configuration attributes ...
/>

Please note according to the MSDN documentation:

"This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging."

If you've already done this but are finding that your session is expiring then increase the ASP.NET HttpSessionState.Timeout value:

For example:

// Increase session timeout to thirty minutes
Session.Timeout = 30;

This value can also be configured in your web.config file in the sessionState configuration element:

<configuration>
  <system.web>
    <sessionState 
      mode="InProc"
      cookieless="true"
      timeout="30" />
  </system.web>
</configuration>

If your script is taking several minutes to execute and there are many concurrent users then consider changing the page to an Asynchronous Page. This will increase the scalability of your application.

The other alternative, if you have administrator access to the server, is to consider this long running operation as a candidate for implementing as a scheduled task or a windows service.

Assuming JQuery ajax, you can add custom headers like -

$.ajax({
  url: url,
  beforeSend: function(xhr) {
    xhr.setRequestHeader("custom_header", "value");
  },
  success: function(data) {
  }
});

Although I take the risk of not being popular I say they are not useful nowadays.

I think they were well intended and useful in the past when for example DELETE told the server to delete the resource found at supplied URL and PUT (with its sibling PATCH) told the server to do update in an idempotent manner.

Things evolved and URLs became virtual (see url rewriting for example) making resources lose their initial meaning of real folder/subforder/file and so, CRUD action verbs covered by HTTP protocol methods (GET, POST, PUT/PATCH, DELETE) lost track.

Let's take an example:

• /api/entity/list/{id} vs GET /api/entity/{id}
• /api/entity/add/{id} vs POST /api/entity
• /api/entity/edit/{id} vs PUT /api/entity/{id}
• /api/entity/delete/{id} vs DELETE /api/entity/{id}

On the left side is not written the HTTP method, essentially it doesn't matter (POST and GET are enough) and on the right side appropriate HTTP methods are used.

Right side looks elegant, clean and professional. Imagine now you have to maintain a code that's been using the elegant API and you have to search where deletion call is done. You'll search for "api/entity" and among results you'll have to see which one is doing DELETE. Or even worse, you have a junior programmer which by mistake switched PUT with DELETE and as URL is the same shit happened.

In my opinion putting the action verb in the URL has advantages over using the appropriate HTTP method for that action even if it's not so elegant. If you want to see where delete call is made you just have to search for "api/entity/delete" and you'll find it straight away.

Building an API without the whole HTTP array of methods makes it easier to be consumed and maintained afterwards

I like this light weight http request client called `unirest'

gem install unirest

usage:

response = Unirest.post "http://httpbin.org/post", 
                        headers:{ "Accept" => "application/json" }, 
                        parameters:{ :age => 23, :foo => "bar" }

response.code # Status code
response.headers # Response headers
response.body # Parsed body
response.raw_body # Unparsed body

Axios is a promise based HTTP client for the browser and Node.js. Axios makes it easy to send asynchronous HTTP requests to REST endpoints and perform CRUD operations. It can be used in plain JavaScript or with a library such as Vue or React.

const axios = require('axios');

        var dataToPost = {
          email: "your email",
          password: "your password"
        };

        let axiosConfiguration = {
          headers: {
              'Content-Type': 'application/json;charset=UTF-8',
              "Access-Control-Allow-Origin": "*",
          }
        };

        axios.post('endpoint or url', dataToPost, axiosConfiguration)
        .then((res) => {
          console.log("Response: ", res);
        })
        .catch((err) => {
          console.log("error: ", err);
        })

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

This should work. You may save the following in a batch file:

TASKKILL /F /IM chrome.exe
start chrome.exe --args --disable-web-security
pause

Instead of using RequestContextHolder directly, you can also use ServletUriComponentsBuilder and its static methods:

• ServletUriComponentsBuilder.fromCurrentContextPath()
• ServletUriComponentsBuilder.fromCurrentServletMapping()
• ServletUriComponentsBuilder.fromCurrentRequestUri()
• ServletUriComponentsBuilder.fromCurrentRequest()

They use RequestContextHolder under the hood, but provide additional flexibility to build new URLs using the capabilities of UriComponentsBuilder.

Example:

ServletUriComponentsBuilder builder = ServletUriComponentsBuilder.fromCurrentRequestUri();
builder.scheme("https");
builder.replaceQueryParam("someBoolean", false);
URI newUri = builder.build().toUri();

SOLUTION FOR Mac

Sample problem but I found my solution with brew.
1. Make sure you have the latest Android Studio installed.
2. Confirm from SDK manager that you have the required SDKs installed.
3. (optional)you could have an AVD installed as well.
4. install Homebrew.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

5. Then run brew update to make sure Homebrew is up to date.

brew update

6. Run brew doctor to make sure everything is safe

brew doctor

7. Add Homebrew's location to your $PATH in your .bash_profile or .zshrc file.

export PATH="/usr/local/bin:$PATH"

8. If you don't have Node already installed, add:

brew install node

9. (Optional) To test out your Node and npm install, try installing Grunt (you might be asked to run with sudo)

npm install -g grunt-cli

10. Install Gradle

brew install gradle

Run: cordova run android --device with you device connected on a Mac and you have gradle working this time.

Just use the rgba tag as your text color. You could use opacity, but that would affect the whole element, not just the text. Say you have a border, it would make that transparent as well.

.text
    {
        font-family: Garamond, serif;
        font-size: 12px;
        color: rgba(0, 0, 0, 0.5);
    }

I did run into another condition with HugeClob in my Oracle database. The dbms_lob.substr only allowed a value of 4000 in the function, ex:

dbms_lob.substr(column,4000,1)

so for my HughClob which was larger, I had to use two calls in select:

select dbms_lob.substr(column,4000,1) part1, 
       dbms_lob.substr(column,4000,4001) part2 from .....

I was calling from a Java app so I simply concatenated part1 and part2 and sent as a email.

None of the above solutions address the generic intention of the original request. What if we don't know the id of the anchor? What if it doesn't have an id? What if it doesn't even have an href parameter (e.g. prev/next icon in a carousel)? What if we want to apply the action to multiple anchors with different models in an agnostic fashion? Here's an example that does something instead of a click, then later simulates the click (for any anchor or other tag):

var clicker = null;
$('a').click(function(e){ 
    clicker=$(this); // capture the clicked dom object
    /* ... do something ... */
    e.preventDefault(); // prevent original click action
});
clicker[0].click(); // this repeats the original click. [0] is necessary.

• carlpett's find-based answer (find . -maxdepth 1 -type f) works in principle, but is not quite the same as using ls: you get a potentially unsorted list of filenames all prefixed with ./, and you lose the ability to apply ls's many options;
  also find invariably finds hidden items too, whereas ls' behavior depends on the presence or absence of the -a or -A options.

  • An improvement, suggested by Alex Hall in a comment on the question is to combine shell globbing with find:

        find * -maxdepth 0 -type f  # find -L * ... includes symlinks to files
    

    • However, while this addresses the prefix problem and gives you alphabetically sorted output, you still have neither (inline) control over inclusion of hidden items nor access to ls's many other sorting / output-format options.

• Hans Roggeman's ls + grep answer is pragmatic, but locks you into using long (-l) output format.

To address these limitations I wrote the fls (filtering ls) utility,

• a utility that provides the output flexibility of ls while also providing type-filtering capability,
• simply by placing type-filtering characters such as f for files, d for directories, and l for symlinks before a list of ls arguments (run fls --help or fls --man to learn more).

Examples:

fls f        # list all files in current dir.
fls d -tA ~  #  list dirs. in home dir., including hidden ones, most recent first
fls f^l /usr/local/bin/c* # List matches that are files, but not (^) symlinks (l)

Installation

Supported platforms

• When installing from the npm registry: Linux and macOS
• When installing manually: any Unix-like platform with Bash

From the npm registry

^{Note: Even if you don't use Node.js, its package manager, npm, works across platforms and is easy to install; try
curl -L https://git.io/n-install | bash}

With Node.js installed, install as follows:

[sudo] npm install fls -g

Note:

• Whether you need sudo depends on how you installed Node.js / io.js and whether you've changed permissions later; if you get an EACCES error, try again with sudo.

• The -g ensures global installation and is needed to put fls in your system's $PATH.

Manual installation

• Download this bash script as fls.
• Make it executable with chmod +x fls.
• Move it or symlink it to a folder in your $PATH, such as /usr/local/bin (macOS) or /usr/bin (Linux).

I assume this is a one-off data scrubbing exercise. Once done, ensure you add database constraints to prevent bad data in the future e.g.

ALTER TABLE Customer ADD
   CONSTRAINT customer_names__whitespace
      CHECK (
             Names NOT LIKE ' %'
             AND Names NOT LIKE '% '
             AND Names NOT LIKE '%  %'
            );

Also consider disallowing other characters (tab, carriage return, line feed, etc) that may cause problems.

It may also be a good time to split those Names into family_name, first_name, etc :)

Note that SimpleDateFormat format pattern Z is for RFC 822 time zone and pattern X is for ISO 8601 (this standard supports single letter time zone names like Z for Zulu).

So new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX") produces a format that can parse both "2013-03-11T01:38:18.309Z" and "2013-03-11T01:38:18.309+0000" and will give you the same result.

Unfortunately, as far as I can tell, you can't get this format to generate the Z for Zulu version, which is annoying.

I actually have more trouble on the JavaScript side to deal with both formats.

You could run it without the -jar command line argument if you happen to know the name of the main class you wish to run:

java -classpath .;myjar.jar;lib/referenced-class.jar my.package.MainClass

If perchance you are using linux, you should use ":" instead of ";" in the classpath.

Short answer - Deleted .m2 folder in {user.home}. E.g. in windows 10 user home is C:\Users\user1. Re-build your project using mvn clean package. Only those dependencies would remain, which are required by the projects.

Long Answer - .m2 folder is just like a normal folder and the content of the folder is built from different projects. I think there is no way to figure out automatically that which library is "old". In fact old is a vague word. There could be so many reasons when a previous version of a library is used in a project, hence determining which one is unused is not possible.

All you could do, is to delete the .m2 folder and re-build all of your projects and then the folder would automatically build with all the required library.

If you are concern about only a particular version of a library to be used in all the projects; it is important that the project's pom should also update to latest version. i.e. if different POMs refer different versions of the library, all will get downloaded in .m2.

Set up the General Query Log.

You are mixing mysqli and mysql extensions, which will not work.

You need to use

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); 

mysqli_select_db($myConnection, "mrmagicadam") or die ("no database");   

mysqli has many improvements over the original mysql extension, so it is recommended that you use mysqli.

Correction to top query above, to allow to run from any database

SELECT COUNT(COLUMN_NAME) FROM [*database*].INFORMATION_SCHEMA.COLUMNS WHERE 
TABLE_CATALOG = 'database' AND TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'table'

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

Complate Angular Way ( Set/Get value by Id ):

// In Html tag

 <button (click) ="setValue()">Set Value</button>
 <input type="text"  #userNameId />

// In component .ts File

    export class testUserClass {
       @ViewChild('userNameId') userNameId: ElementRef;

      ngAfterViewInit(){
         console.log(this.userNameId.nativeElement.value );
       }

      setValue(){

based on @LindseyD answer I created a simple BAT file, that opens cygwin in current directory, it may be useful (for me it is). Assuming that You have cygwin's bin directory in PATH.

FOR /F %%x IN ('sh -c pwd') DO bash -l -i -c 'cd %%x; exec bash'

You can have awk do it all without using cut:

awk '{print substr($7,index($7,"=")+1)}' inputfile

You could use split() instead of substr(index()).

Try this:

SElECT * FROM STUDENTS WHERE LEN(CAST(STUDENTID AS VARCHAR)) > 0

With this you get the rows where STUDENTID contains text

USe this function for date comparison in javascript:

    function fn_DateCompare(DateA, DateB) {

      if (parseFloat(msDateA) < parseFloat(msDateB))
        return -1;  // less than
      else if (parseFloat(msDateA) == parseFloat(msDateB))
        return 0;  // equal
      else if (parseFloat(msDateA) > parseFloat(msDateB))
        return 1;  // greater than
      else
        return null;  // error
  }

An other solution is to use the special variable ansible_limit which is the contents of the --limit CLI option for the current execution of Ansible.

- hosts: "{{ ansible_limit | default(omit) }}"

If the --limit option is omitted, then Ansible issues a warning, but does nothing since no host matched.

[WARNING]: Could not match supplied host pattern, ignoring: None

The point is semantics. In assertTrue, you are asserting that the expression is true. If it is not, then it will display the message and the assertion will fail. In assertFalse, you are asserting that an expression evaluates to false. If it is not, then the message is displayed and the assertion fails.

assertTrue (message, value == false) == assertFalse (message, value);

These are functionally the same, but if you are expecting a value to be false then use assertFalse. If you are expecting a value to be true, then use assertTrue.

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

Here is email code I used in one of my databases. I just made variables for the person I wanted to send it to, CC, subject, and the body. Then you just use the DoCmd.SendObject command. I also set it to "True" after the body so you can edit the message before it automatically sends.

Public Function SendEmail2()

Dim varName As Variant          
Dim varCC As Variant            
Dim varSubject As Variant      
Dim varBody As Variant          

varName = "[email protected]"
varCC = "[email protected], [email protected]"
'separate each email by a ','

varSubject = "Hello"
'Email subject

varBody = "Let's get ice cream this week"

'Body of the email
DoCmd.SendObject , , , varName, varCC, , varSubject, varBody, True, False
'Send email command. The True after "varBody" allows user to edit email before sending.
'The False at the end will not send it as a Template File

End Function

That won't work in IE<9 though, however, you can make IEs support that using:

CSS3Pie

PIE makes Internet Explorer 6-8 capable of rendering several of the most useful CSS3 decoration features.

This is a common concern.

The default outline that browsers render is ugly.

See this for example:

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}

<form>_x000D_
  <label>Click to see the input below to see the outline</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

The most common "fix" that most recommend is outline:none - which if used incorrectly - is disaster for accessibility.

So...of what use is the outline anyway?

There's a very dry-cut website I found which explains everything well.

It provides visual feedback for links that have "focus" when navigating a web document using the TAB key (or equivalent). This is especially useful for folks who can't use a mouse or have a visual impairment. If you remove the outline you are making your site inaccessible for these people.

Ok, let's try it out same example as above, now use the TAB key to navigate.

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}

<form>_x000D_
  <label>Click on this text and then use the TAB key to naviagte inside the snippet.</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

Notice how you can tell where the focus is even without clicking the input?

Now, let's try outline:none on our trusty <input>

So, once again, use the TAB key to navigate after clicking the text and see what happens.

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}_x000D_
_x000D_
input {_x000D_
  outline: none;_x000D_
}

<form>_x000D_
  <label>Click on this text and then use the TAB key to naviagte inside the snippet.</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

See how it's more difficult to figure out where the focus is? The only telling sign is the cursor blinking. My example above is overly simplistic. In real-world situations, you wouldn't have only one element on the page. Something more along the lines of this.

    <input type="radio" name="gender" value="other"> Other_x000D_

    <input id="GET-name" type="text" name="name">_x000D_

    <input id="POST-name" type="text" name="name">_x000D_

      <label for="radio">Click me</label>_x000D_
    </fieldset>_x000D_
  </form>_x000D_
_x000D_
</div>

Now compare that to the same template if we keep the outline:

.wrapper {_x000D_
  width: 500px;_x000D_
  max-width: 100%;_x000D_
  margin: 0 auto;_x000D_

}

<div class="wrapper">_x000D_

    <input type="radio" name="gender" value="other"> Other_x000D_
  </form>_x000D_
_x000D_

_x000D_

    <input id="GET-name" type="text" name="name">_x000D_

_x000D_
_x000D_
  <form>_x000D_
    <label for="POST-name">Name:</label>_x000D_
    <input id="POST-name" type="text" name="name">_x000D_

  <form>_x000D_
    <fieldset>_x000D_
      <legend>Title</legend>_x000D_
      <input type="radio" name="radio" id="radio">_x000D_
      <label for="radio">Click me</label>_x000D_

  </form>_x000D_
_x000D_
</div>

So we have established the following

1. Outlines are ugly
2. Removing them makes life more difficult.

So what's the answer?

Remove the ugly outline and add your own visual cues to indicate focus.

Here's a very simple example of what I mean.

I remove the outline and add a bottom border on :focus and :active. I also remove the default borders on the top, left and right sides by setting them to transparent on :focus and :active (personal preference)

form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}_x000D_
_x000D_
input {_x000D_
  outline: none_x000D_
}_x000D_
_x000D_
input:focus,_x000D_
input:active {_x000D_
  border-color: transparent;_x000D_
  border-bottom: 2px solid red_x000D_
}

<form>_x000D_
  <label>Click to see the input below to see the outline</label>_x000D_
  <input type="text" placeholder="placeholder text" />_x000D_
</form>

So, we try the approach above with our "real-world" example from earlier:

.wrapper {_x000D_
  width: 500px;_x000D_
  max-width: 100%;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
_x000D_
form,_x000D_
label {_x000D_
  margin: 1em auto;_x000D_
}_x000D_
_x000D_
label {_x000D_
  display: block;_x000D_
}_x000D_
_x000D_
input {_x000D_
  outline: none_x000D_
}_x000D_
_x000D_
input:focus,_x000D_
input:active {_x000D_
  border-color: transparent;_x000D_
  border-bottom: 2px solid red_x000D_
}

<div class="wrapper">_x000D_

    <input type="text" placeholder="placeholder text" />_x000D_
    <input type="text" placeholder="placeholder text" />_x000D_

_x000D_

    <input type="text" name="firstname"><br> Last name:<br>_x000D_
    <input type="text" name="lastname">_x000D_

_x000D_
_x000D_
  <form>_x000D_
    <input type="radio" name="gender" value="male" checked> Male<br>_x000D_
    <input type="radio" name="gender" value="female"> Female<br>_x000D_
    <input type="radio" name="gender" value="other"> Other_x000D_

_x000D_
_x000D_
  <form>_x000D_
    <label for="GET-name">Name:</label>_x000D_
    <input id="GET-name" type="text" name="name">_x000D_
  </form>_x000D_
_x000D_
_x000D_
  <form>_x000D_
    <label for="POST-name">Name:</label>_x000D_
    <input id="POST-name" type="text" name="name">_x000D_
  </form>_x000D_
_x000D_
_x000D_
  <form>_x000D_
    <fieldset>_x000D_
      <legend>Title</legend>_x000D_
      <input type="radio" name="radio" id="radio">_x000D_
      <label for="radio">Click me</label>_x000D_
    </fieldset>_x000D_
  </form>_x000D_
_x000D_
</div>

This can be extended further by using external libraries that build on the idea of modifying the "outline" as opposed to removing it entirely like Materialize

You can end up with something that is not ugly and works with very little effort

By using cursor you can easily iterate through records individually and print records separately or as a single message including all the records.

DECLARE @CustomerID as INT;
declare @msg varchar(max)
DECLARE @BusinessCursor as CURSOR;

SET @BusinessCursor = CURSOR FOR
SELECT CustomerID FROM Customer WHERE CustomerID IN ('3908745','3911122','3911128','3911421')

OPEN @BusinessCursor;
    FETCH NEXT FROM @BusinessCursor INTO @CustomerID;
    WHILE @@FETCH_STATUS = 0
        BEGIN
            SET @msg = '{
              "CustomerID": "'+CONVERT(varchar(10), @CustomerID)+'",
              "Customer": {
                "LastName": "LastName-'+CONVERT(varchar(10), @CustomerID) +'",
                "FirstName": "FirstName-'+CONVERT(varchar(10), @CustomerID)+'",    
              }
            }|'
        print @msg
    FETCH NEXT FROM @BusinessCursor INTO @CustomerID;
END

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

You need to name the file in both directory paths.

scp [email protected]:/dir/of/file.txt \local\dir\file.txt

Just a little addition to psycho brm´s answer (his version doesn't work in IE<=8). This code is cross-browser compatible:

function explode (s, separator, limit)
{
    var arr = s.split(separator);
    if (limit) {
        arr.push(arr.splice(limit-1, (arr.length-(limit-1))).join(separator));
    }
    return arr;
}

A little late to the party, but since I was looking for it (and I might need to find it again sometime), here's what I did to include version, company name, etc. into my C++ DLL under VS2013 Express:

1. Created and edited a dllproj.rc file, as indicated previously.
2. Added the line "rc.exe dllproj.rc" as a pre-build step in the DLL project.
3. Added dllproj.res to the resource folder for the project.

Hope this helps!

I have noticed that after installation of SQL server 2012 express on Windows 10 you must install ENU\x64\SqlLocalDB.MSI from official Microsoft download site. After that, you could run SqlLocalDB.exe.

This solution will only add the border, the body of the LinearLayout will be transparent.

First, Create this border drawable in the drawable folder, border.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android= "http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <stroke android:width="2dp" android:color="#ec0606"/>
    <corners android:radius="10dp"/>
</shape>

Then, in your LinearLayout View, add the border.xml as the background like this

<LinearLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/border">

The order of the importing was the reason why I was having issues:

a.py:

############
# this is a problem
# move this to below
#############
from b import NewThing

class ProblemThing(object):
    pass

class A(object):
   ###############
   # add it here
   # from b import NewThing
   ###############
   nt = NewThing()
   pass

b.py:

from a import ProblemThing

class NewThing(ProblemThing):
    pass

Just another example of how it might look, similar to RichieHindie's answer, but with classes.

Standard C doesn't define binary constants. There's a GNU (I believe) extension though (among popular compilers, clang adapts it as well): the 0b prefix:

int foo = 0b1010;

If you want to stick with standard C, then there's an option: you can combine a macro and a function to create an almost readable "binary constant" feature:

#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
        unsigned long long i = 0;
        while (*s) {
                i <<= 1;
                i += *s++ - '0';
        }
        return i;
}

And then you can use it like this:

int foo = B(1010);

If you turn on heavy compiler optimizations, the compiler will most likely eliminate the function call completely (constant folding) or will at least inline it, so this won't even be a performance issue.

Proof:

The following code:

#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
#include <string.h>


#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
    unsigned long long i = 0;
    while (*s) {
        i <<= 1;
        i += *s++ - '0';
    }
    return i;
}

int main()
{
    int foo = B(001100101);

    printf("%d\n", foo);

    return 0;
}

has been compiled using clang -o baz.S baz.c -Wall -O3 -S, and it produced the following assembly:

    .section    __TEXT,__text,regular,pure_instructions
    .globl  _main
    .align  4, 0x90
_main:                                  ## @main

    .asciz   "%d\n"


.subsections_via_symbols

So clang completely eliminated the call to the function, and replaced its return value with 101. Neat, huh?

I believe the only sanest way to do this is to manually iterate through the array.

for (int i = 0; i < list.length; i++) {
  if (list[i] == 'e') {
    System.out.println(i);
    break;
  }
}

The typical solution to this is to write your own function to clone an object. If you are able to provide copy constructors and copy assignement operators, this may be as far as you need to go.

class Foo
{ 
public:
  Foo();
  Foo(const Foo& rhs) { /* copy construction from rhs*/ }
  Foo& operator=(const Foo& rhs) {};
};

// ...

Foo orig;
Foo copy = orig;  // clones orig if implemented correctly

Sometimes it is beneficial to provide an explicit clone() method, especially for polymorphic classes.

class Interface
{
public:
  virtual Interface* clone() const = 0;
};

class Foo : public Interface
{
public:
  Interface* clone() const { return new Foo(*this); }
};

class Bar : public Interface
{
public:
  Interface* clone() const { return new Bar(*this); }
};


Interface* my_foo = /* somehow construct either a Foo or a Bar */;
Interface* copy = my_foo->clone();

EDIT: Since Stack has no member variables, there's nothing to do in the copy constructor or copy assignment operator to initialize Stack's members from the so-called "right hand side" (rhs). However, you still need to ensure that any base classes are given the opportunity to initialize their members.

You do this by calling the base class:

Stack(const Stack& rhs) 
: List(rhs)  // calls copy ctor of List class
{
}

Stack& operator=(const Stack& rhs) 
{
  List::operator=(rhs);
  return * this;
};

Here's one view on the singleton methods:

I have found these various "singleton" methods to be useful for passing a single value to an API that requires a collection of that value. Of course, this works best when the code processing the passed-in value does not need to add to the collection.

You can use strcpy but remember to end the array with '\0'

char array[20]; char string[100];

array[0]='1'; array[1]='7'; array[2]='8'; array[3]='.'; array[4]='9'; array[5]='\0';
strcpy(string, array);
printf("%s\n", string);

To those that are incline to use GUI:

Click Right mouse button on procecdure name then select Test

Then in new window you will see script generated just add the parameters and click on Start Debugger or F9

Hope this saves you some time.

If you're using AngularJS, the 'json' filter should do it:

<span>{{someObject | json}}</span>

Please take a good look here: http://jquerymobile.com/test/docs/api/methods.html

$.mobile.changePage() is to change from one page to another, and the parameter can be a url or a page object. ( only #result will also work )

$.mobile.page() isn't recommended anymore, please use .trigger( "create"), see also: JQuery Mobile .page() function causes infinite loop?

Important: Create vs. refresh: An important distinction

Note that there is an important difference between the create event and refresh method that some widgets have. The create event is suited for enhancing raw markup that contains one or more widgets. The refresh method that some widgets have should be used on existing (already enhanced) widgets that have been manipulated programmatically and need the UI be updated to match.

For example, if you had a page where you dynamically appended a new unordered list with data-role=listview attribute after page creation, triggering create on a parent element of that list would transform it into a listview styled widget. If more list items were then programmatically added, calling the listview’s refresh method would update just those new list items to the enhanced state and leave the existing list items untouched.

$.mobile.refresh() doesn't exist i guess

So what are you using for your results? A listview? Then you can update it by doing:

$('ul').listview('refresh');

Example: http://operationmobile.com/dont-forget-to-call-refresh-when-adding-items-to-your-jquery-mobile-list/

Otherwise you can do:

$('#result').live("pageinit", function(){ // or pageshow
    // your dom manipulations here
});

Why would you use -z? To test if a string is non-empty, you typically use -n:

if test -n "$errorstatus"; then
  echo errorstatus is not empty
fi

Let's clarify first what is a CPU and what is a core, a central processing unit CPU, can have multiple core units, those cores are a processor by itself, capable of execute a program but it is self contained on the same chip.

In the past one CPU was distributed among quite a few chips, but as Moore's Law progressed they made to have a complete CPU inside one chip (die), since the 90's the manufacturer's started to fit more cores in the same die, so that's the concept of Multi-core.

In these days is possible to have hundreds of cores on the same CPU (chip or die) GPUs, Intel Xeon. Other technique developed in the 90's was simultaneous multi-threading, basically they found that was possible to have another thread in the same single core CPU, since most of the resources were duplicated already like ALU, multiple registers.

So basically a CPU can have multiple cores each of them capable to run one thread or more at the same time, we may expect to have more cores in the future, but with more difficulty to be able to program efficiently.

Well, image loading time from the Internet has many solutions. You may also use the library Android-Query. It will give you all the required activity. Make sure what you want to do and read the library wiki page. And solve the image loading restriction.

This is my code:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;
    if (v == null) {
        LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.row, null);
    }

    ImageView imageview = (ImageView) v.findViewById(R.id.icon);
    AQuery aq = new AQuery(convertView);

    String imageUrl = "http://www.vikispot.com/z/images/vikispot/android-w.png";

    aq.id(imageview).progress(this).image(imageUrl, true, true, 0, 0, new BitmapAjaxCallback() {
        @Override
        public void callback(String url, ImageView iv, Bitmap bm, AjaxStatus status) {
            iv.setImageBitmap(bm);
        }
    ));

    return v;
}

It should be solve your lazy loading problem.

tl;dr

myJavaUtilDate.toInstant()
              .plusHours( 8 )

Or…

myJavaUtilDate.toInstant()                // Convert from legacy class to modern class, an `Instant`, a point on the timeline in UTC with resolution of nanoseconds.
              .plus(                      // Do the math, adding a span of time to our moment, our `Instant`. 
                  Duration.ofHours( 8 )   // Specify a span of time unattached to the timeline.
               )                          // Returns another `Instant`. Using immutable objects creates a new instance while leaving the original intact.

Using java.time

The java.time framework built into Java 8 and later supplants the old Java.util.Date/.Calendar classes. Those old classes are notoriously troublesome. Avoid them.

Use the toInstant method newly added to java.util.Date to convert from the old type to the new java.time type. An Instant is a moment on the time line in UTC with a resolution of nanoseconds.

Instant instant = myUtilDate.toInstant();

You can add hours to that Instant by passing a TemporalAmount such as Duration.

Duration duration = Duration.ofHours( 8 );
Instant instantHourLater = instant.plus( duration );

To read that date-time, generate a String in standard ISO 8601 format by calling toString.

String output = instantHourLater.toString();

You may want to see that moment through the lens of some region’s wall-clock time. Adjust the Instant into your desired/expected time zone by creating a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Alternatively, you can call plusHours to add your count of hours. Being zoned means Daylight Saving Time (DST) and other anomalies will be handled on your behalf.

ZonedDateTime later = zdt.plusHours( 8 );

You should avoid using the old date-time classes including java.util.Date and .Calendar. But if you truly need a java.util.Date for interoperability with classes not yet updated for java.time types, convert from ZonedDateTime via Instant. New methods added to the old classes facilitate conversion to/from java.time types.

java.util.Date date = java.util.Date.from( later.toInstant() );

For more discussion on converting, see my Answer to the Question, Convert java.util.Date to what “java.time” type?.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You're calling writer.close(); after you've done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method.

public void writeToFile(){
    String file_text= pedStatusText + "     " + gatesStatus + "     " + DrawBridgeStatusText;
    try {
        writer.write(file_text);
        writer.flush();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

And add a method cleanUp to close the stream.

public void cleanUp() {
     writer.close();
}

This means that you have the responsibility to make sure that you're calling cleanUp when you're done writing to the file. Failure to do this will result in memory leaks and resource locking.

EDIT: You can create a new stream each time you want to write to the file, by moving writer into the writeToFile() method..

 public void writeToFile() {
    FileWriter writer = new FileWriter("status.txt", true);
    // ... Write to the file.

    writer.close();
 }

simply,

select sysdate-1 from dual

Actually, to query the team_name, just add it in brackets to the last line. Apart from that, it seems to work on Python 2.7.3 on command line.

from urllib2 import urlopen
import json

url = 'http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1'
response = urlopen(url)
json_obj = json.load(response)

for i in json_obj['team']:
    print i['team_name']

Even I run npm install -g npm@4, it is not ok for me.

Finally, I download and install the old node.js version.

It is npm version 4.

You can choose any version here https://nodejs.org/download/release/

To take first 5 elements better use expression like this one:

var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5);

or

var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5).OrderBy([ORDER EXPR]);

It will be faster than orderBy variant, because LINQ engine will not scan trough all list due to delayed execution, and will not sort all array.

class MyList : IEnumerable<int>
{

    int maxCount = 0;

    public int RequestCount
    {
        get;
        private set;
    }
    public MyList(int maxCount)
    {
        this.maxCount = maxCount;
    }
    public void Reset()
    {
        RequestCount = 0;
    }

        {
            RequestCount++;
            yield return i++;
        }
    }

        list.Reset();

Aangular 2 final has updated APIs. They have added many methods for this.

To update the form control from controller do this:

this.form.controls['dept'].setValue(selected.id);

this.form.controls['dept'].patchValue(selected.id);

No need to reset the errors

On top of your lastest jsfiddle, you just missed one thing:

#sidebar_wrap {
  width:40%;
  height:200px;
  background:green;
  float:right;
}
#sidebar {
  width:inherit;
  margin-top:10px;
  background-color:limegreen;
  position:fixed;
  max-width: 240px; /*This is you missed*/
}

But, how this will solve your problem? Simple, lets explain why is bigger than expect first.

Fixed element #sidebar will use window width size as base to get its own size, like every other fixed element, once in this element is defined width:inherit and #sidebar_wrap has 40% as value in width, then will calculate window.width * 40%, then when if your window width is bigger than your .container width, #sidebar will be bigger than #sidebar_wrap.

This is way, you must set a max-width in your #sidebar_wrap, to prevent to be bigger than #sidebar_wrap.

Check this jsfiddle that shows a working code and explain better how this works.

Accepted answer doesn't work with "use strict" as the "with" statement throws an error. So instead:

$.post(url, function (data) {
    var w = window.open('about:blank', 'windowname');
    w.document.write(data);
    w.document.close();
});

Also, make sure 'windowname' doesn't have any spaces in it because that will fail in IE :)

You can also use template matching to detect shapes inside an image.

To show the commits I have staged that are ready to push I do

git log remotes/trunk~4..HEAD --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s" --date=short | awk -F'\t' '{gsub(/[, ]/,"",$2);gsub(/HEAD/, "\033[1;36mH\033[00m",$2);gsub(/master/, "\033[1;32mm\033[00m",$2);gsub(/trunk/, "\033[1;31mt\033[00m",$2);print $1 "\t" gensub(/([\(\)])/, "\033[0;33m\\1\033[00m","g",$2) $3}' | less -eiFRXS

The output looks something like:

ef87da7 2013-01-17 haslers      (Hm)Fix NPE in Frobble
8f6d80f 2013-01-17 haslers      Refactor Frobble

a1db9ef 2013-01-17 haslers      Add Frobble Widget

Where the first column appears in yellow, and the 'H' 'm' and 't' in parentesis show the HEAD, master and trunk and appear in their usual "--decorate" colors

Here it is with line breaks so you can see what it's doing:

git log remotes/trunk~4..HEAD --date=short
    --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s"
    | awk -F'\t' '{
         gsub(/[, ]/,"",$2);
         gsub(/HEAD/, "\033[1;36mH\033[00m",$2);
         gsub(/master/, "\033[1;32mm\033[00m",$2);
         gsub(/trunk/, "\033[1;31mt\033[00m",$2);
         print $1 "\t" gensub(/([\(\)])/, "\033[0;33m\\1\033[00m","g",$2) $3}'

I have aliased to "staged" with:

git config alias.staged '!git log remotes/trunk~4..HEAD --date=short --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s" | awk -F"\t" "{gsub(/[, ]/,\"\",\$2);gsub(/HEAD/, \"\033[1;36mH\033[00m\",\$2);gsub(/master/, \"\033[1;32mm\033[00m\",\$2);gsub(/trunk/, \"\033[1;31mt\033[00m\",\$2);print \$1 \"\t\" gensub(/([\(\)])/, \"\033[0;33m\\\\\1\033[00m\",\"g\",\$2) \$3}"'

(Is there an easier way to escape that? it was a bit tricky to work out what needed escaping)

If your are referring to two worksheets please use this formula

=COUNTIF(Worksheet2!$A$1:$A$50,Worksheet1cellA1)

In case referring to to more than two worksheets please use this formula

=COUNTIF(Worksheet2!$A$1:$A$50,Worksheet1cellA1)+=COUNTIF
(Worksheet3!$A$1:$A$50,Worksheet1cellA1)+=
               COUNTIF(Worksheet4!$A$1:$A$50,Worksheet1cellA1)

The accepted answer doesn't work if some package vendors it's own copy of urllib3, in which case this will still work:

import warnings

warnings.filterwarnings('ignore', message='Unverified HTTPS request')

(SELECT CASE WHEN (SELECT  Salary FROM tbl_Salary WHERE Code=102 AND Month=1 AND Year=2020 )=0 THEN 'Pending'
WHEN (SELECT  Salary FROM tbl_Salary WHERE Code=102 AND Month=1 AND Year=2020 AND )<>0 THEN (SELECT CASE  WHEN ISNULL(ChequeNo,0) IS NOT NULL   THEN 'Deposit' ELSE 'Pending' END AS Deposite FROM tbl_EEsi WHERE  AND (Month= 1) AND (Year = 2020) AND )END AS Stat)

On newer versions of Windows (Windows 10 and Windows Server 2016) the tasks you create are located in C:\Windows\Tasks. They will have the extension .job

For example if you create the task "DoWork" it will create the task in

C:\Windows\Tasks\DoWork.job

I also faced the same problem. In my case I was hitting a java.util.UnknownFormatConversionException. I figured this out only after putting a printStackTrace call. I resolved it by changing my code as shown below.

from:

StringBuilder sb = new StringBuilder();
sb.append("***** Test Details *****\n");
String.format("[Test: %1]", sb.toString());

to:

String.format("[Test: %s]", sb.toString());

Those are automatic properties

Basically another way of writing a property with a backing field.

public class Genre
{
    private string _name;

    public string Name 
    { 
      get => _name;
      set => _name = value;
    }
}

TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)

Here is the FIX for 2.3 and below when using colours:

• Android: Entire ListView changes color on focus, not just ListView child item

As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape drawable containing the colour you want, and to use that instead of the colour.

I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).

one way you could handle this is with a generator. Instead of calling the function, yield it; then whatever is consuming the generator can send the result of calling it back into the generator, or a sentinel if the generator failed: The trampoline that accomplishes the above might look like so:

def consume_exceptions(gen):
    action = next(gen)
    while True:
        try:
            result = action()
        except Exception:
            # if the action fails, send a sentinel
            result = None

        try:
            action = gen.send(result)
        except StopIteration:
            # if the generator is all used up, result is the return value.
            return result

a generator that would be compatible with this would look like this:

def do_smth1():
    1 / 0

def do_smth2():
    print "YAY"

def do_many_things():
    a = yield do_smth1
    b = yield do_smth2
    yield "Done"

>>> consume_exceptions(do_many_things())
YAY

Note that do_many_things() does not call do_smth*, it just yields them, and consume_exceptions calls them on its behalf

Typing SHOW GRANTS FOR 'root'@'localhost'; showed me some obscured password, so I logged into mysql of that system using HeidiSQL on another system (using root as the username and the corresponding password) and typed
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'thepassword' WITH GRANT OPTION;

and it worked when I went back to the system and logged on using
mysql -uroot -pthepassword;

I'm not really sure, I guess it depends on the task: how often to run, how much complicated and how much direct communication with the rails project is needed etc. I guess if there was just "One Best Way" to do something, there wouldn't be so many different ways to do it.

At my last job in a Rails project, we needed to make a batch invitation mailer (survey invitations, not spamming) which should send the planned mails whenever the server had time. I think we were going to use daemon tools to run the rake tasks I had created.

Unfortunately, our company had some money problems and was "bought" by the main rival so the project was never completed, so I don't know what we would eventually have used.

I tried this in Ubuntu 18.04 and is the only solution that worked for me:

ALTER USER my_user@'%' IDENTIFIED WITH mysql_native_password BY 'password';

Try this..

function getdata($csvFile){
    $file_handle = fopen($csvFile, 'r');
    while (!feof($file_handle) ) {
        $line_of_text[] = fgetcsv($file_handle, 1024);
    }
    fclose($file_handle);
    return $line_of_text;
}


// Set path to CSV file
$csvFile = 'test.csv';

$csv = getdata($csvFile);
echo '<pre>';
print_r($csv);
echo '</pre>';

If you are using PyQt, then for normal work, you should add "shell":"true" value, this looks like:

{
  "cmd": ["c:/Python32/python.exe", "-u", "$file"],
  "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
  "selector": "source.python",
  "shell":"true"
}

You need to use the wildcard % :

SELECT * from games WHERE (lower(title) LIKE 'age of empires III%');

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

A variable is declared if accessing the variable name will not produce a ReferenceError. The expression typeof variableName !== 'undefined' will be false in only one of two cases:

• the variable is not declared (i.e., there is no var variableName in scope), or
• the variable is declared and its value is undefined (i.e., the variable's value is not defined)

Otherwise, the comparison evaluates to true.

If you really want to test if a variable is declared or not, you'll need to catch any ReferenceError produced by attempts to reference it:

var barIsDeclared = true; 
try{ bar; }
catch(e) {
    if(e.name == "ReferenceError") {
        barIsDeclared = false;
    }
}

If you merely want to test if a declared variable's value is neither undefined nor null, you can simply test for it:

if (variableName !== undefined && variableName !== null) { ... }

Or equivalently, with a non-strict equality check against null:

if (variableName != null) { ... }

Both your second example and your right-hand expression in the && operation tests if the value is "falsey", i.e., if it coerces to false in a boolean context. Such values include null, false, 0, and the empty string, not all of which you may want to discard.

Are you setting up a local 'm4' directory? e.g.,

> aclocal -I m4 --install

Some packages come with an autogen.sh or initgen.sh shell script to run glibtoolize, autoheader, autoconf, automake. Here's an autogen.sh script I use:

#! /bin/sh

case `uname` in Darwin*) glibtoolize --copy ;;
  *) libtoolize --copy ;; esac

autoheader
aclocal -I m4 --install
autoconf

automake --foreign --add-missing --force-missing --copy

EDIT

You may need to add ACLOCAL_AMFLAGS = -I m4 to the top-level Makefile.am.

I also wanted to run python files directly from Notepad++. Most common option found online is using builtin option Run. Then you have two options:

1. Run python file in console (in Windows it is Command Prompt) with code something like this (links: ):

   C:\Path\to\Python\python.exe "$(FULL_CURRENT_PATH)"
   

   (If your console window immediately closes after running then you can add cmd /k to your code. Links: ) This works fine, and you can even run files in interactive mode by adding -i to your code (links: ).

2. Run python program in IDLE with code something like this (links: , in these links C:\Path\to\Python\Lib\idlelib\idle.py is used, but I am using C:\Path\to\Python\Lib\idlelib\idle.bat instead, because idle.bat sets the right current working directory automatically):

   C:\Path\to\Python\Lib\idlelib\idle.bat "$(FULL_CURRENT_PATH)"
   

   Actually, this doesn't run your program in IDLE Shell, but instead it opens your python file in IDLE Editor and then you need to click Run Module (or click F5) to run the program. So it opens your file in IDLE Editor and then you need run it from there, which defeats the purpose of running python files from Notepad++.

   But, searching online, I found option which adds '-r' to your code (links: ):

   C:\Path\to\Python\Lib\idlelib\idle.bat -r "$(FULL_CURRENT_PATH)"
   

   This will run your python program in IDLE Shell and because it is in IDLE it is by default in interactive mode.

Problem with running your python files via builtin Run option is that each time you run your python file, you open new console or IDLE window and lose all output from previous executions. This might not be important to some, but when I started to program in python, I used Python IDLE, so I got used to running python file multiple times in same IDLE Shell window. Also problem with running python programs from Notepad++ is that you need to manually save your file and then click Run (or press F5). To solve these problems (AFAIK*) you need to use Notepad++ Plugins. The best plugin for running python files from Notepad++ is NppExec. (I also tried PyNPP and Python Script. PyNPP runs python files in console, it works, but you can do that without plugin via builtin Run option and Python Script is used for running scripts that interact with Notepad++ so you can't run your python files.) To run your python file with NppExec plugin you need to go to Plugins -> NppExec -> Execute and then type in something like this (links: ):

C:\Path\to\Python\python.exe "$(FULL_CURRENT_PATH)"

With NppExec you can also save your python file before run with npp_save command, set working directory with cd "$(CURRENT_DIRECTORY)" command or run python program in interactive mode with -i command. I found many links ( ) online that mention these options, but best use of NppExec to run python programs I found at NppExec's Manual which has chapter 4.6.4. Running Python & wxPython with this code:

npp_console -  // disable any output to the Console
npp_save  // save current file (a .py file is expected)
cd "$(CURRENT_DIRECTORY)"  // use the current file's dir
set local @exit_cmd_silent = exit()  // allows to exit Python automatically
set local PATH_0 = $(SYS.PATH)  // current value of %PATH%
env_set PATH = $(SYS.PATH);C:\Python27  // use Python 2.7
npp_setfocus con  // set the focus to the Console
npp_console +  // enable output to the Console
python -i -u "$(FILE_NAME)"  // run Python's program interactively
npp_console -  // disable any output to the Console
env_set PATH = $(PATH_0)  // restore the value of %PATH%
npp_console +  // enable output to the Console

All you need to do is copy this code and change your python directory if you use some other python version (e.g.* I am using python 3.4 so my directory is C:\Python34). This code works perfectly, but there is one line I added to this code so I can run python program multiple times without loosing previous output:

npe_console m- a+

a+ is to enable the "append" mode which keeps the previous Console's text and does not clear it.

m- turns off console's internal messages (those are in green color)

The final code that I use in NppExec's Execute window is:

npp_console -  // disable any output to the Console
npp_save  // save current file (a .py file is expected)
cd "$(CURRENT_DIRECTORY)"  // use the current file's dir
set local @exit_cmd_silent = exit()  // allows to exit Python automatically
set local PATH_0 = $(SYS.PATH)  // current value of %PATH%
env_set PATH = $(SYS.PATH);C:\Python34  // use Python 3.4
npp_setfocus con  // set the focus to the Console
npe_console m- a+
npp_console +  // enable output to the Console
python -i -u "$(FILE_NAME)"  // run Python's program interactively
npp_console -  // disable any output to the Console
env_set PATH = $(PATH_0)  // restore the value of %PATH%
npp_console +  // enable output to the Console

You can save your NppExec's code, and assign a shortcut key to this NppExec's script. (You need to open Advanced options of NppExec's plugin, select your script in the Associated script drop-down list, press the Add/Modify, restart Notepad++ , go to Notepad++'es Settings -> Shortcut Mapper -> Plugin commands, select your script, click Modify and assign a shortcut key. I wanted to put F5 as my shortcut key, to do that you need to change shortcut key for builtin option Run to something else first.) Links to chapters from NppExec's Manual that explain how to save you NppExec's code and assign a shortcut key: NppExec's "Execute...", NppExec's script.

P.S.*: With NppExec plugin you can add Highlight Filters (found in Console Output Filters...) that highlight certain lines. I use it to highlight error lines in red, to do that you need to add Highlight masks: *File "%FILE%", line %LINE%, in <*> and Traceback (most recent call last): like this.

For those of you who are setting up MSYS Git on Windows using PuTTY via the standard command prompt, the way to add a host to PuTTY's cache is to run

> plink.exe <host>

For example:

> plink.exe codebasehq.com

The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 2048 2e:db:b6:22:f7:bd:48:f6:da:72:bf:59:d7:75:d7:4e
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)

Just answer y, and then Ctrl+C the rest.

Do check the fingerprint though. This warning is there for a good reason. Fingerprints for some git services (please edit to add more):

• Gitorious: 7e:af:8d:ec:f0:39:5e:ba:52:16:ce:19:fa:d4:b8:7d

The following should work:

$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', '>=', $now)
                           ->where('reservation_from', '<=', $to)
                           ->get();

import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

if you want to sort x in-place, you can also:

x.sort(key=operator.attrgetter('score'))

as said above simple line of code will fix your problems

border: 1px solid #000;

There is another option to add border to your image and that with photoshop you can see how it's done with this tutorial below: http://bannercheapdesign.com/articles-and-tutorials/learn-how-to-add-border-to-your-banner-design-using-photoshop/

Let's decompile to see what GCC 4.8 does with it

Without __builtin_expect

#include "stdio.h"
#include "time.h"

int main() {
    /* Use time to prevent it from being optimized away. */
    int i = !time(NULL);
    if (i)
        printf("%d\n", i);
    puts("a");
    return 0;
}

Compile and decompile with GCC 4.8.2 x86_64 Linux:

gcc -c -O3 -std=gnu11 main.c
objdump -dr main.o

Output:

0000000000000000 <main>:
   0:       48 83 ec 08             sub    $0x8,%rsp
   4:       31 ff                   xor    %edi,%edi
   6:       e8 00 00 00 00          callq  b <main+0xb>

   b:       48 85 c0                test   %rax,%rax
   e:       75 14                   jne    24 <main+0x24>
  10:       ba 01 00 00 00          mov    $0x1,%edx
  15:       be 00 00 00 00          mov    $0x0,%esi
                    16: R_X86_64_32 .rodata.str1.1
  1a:       bf 01 00 00 00          mov    $0x1,%edi
  1f:       e8 00 00 00 00          callq  24 <main+0x24>
                    20: R_X86_64_PC32       __printf_chk-0x4
  24:       bf 00 00 00 00          mov    $0x0,%edi
                    25: R_X86_64_32 .rodata.str1.1+0x4
  29:       e8 00 00 00 00          callq  2e <main+0x2e>
                    2a: R_X86_64_PC32       puts-0x4
  2e:       31 c0                   xor    %eax,%eax
  30:       48 83 c4 08             add    $0x8,%rsp
  34:       c3                      retq

The instruction order in memory was unchanged: first the printf and then puts and the retq return.

With __builtin_expect

Now replace if (i) with:

if (__builtin_expect(i, 0))

and we get:

0000000000000000 <main>:
   0:       48 83 ec 08             sub    $0x8,%rsp
   4:       31 ff                   xor    %edi,%edi
   6:       e8 00 00 00 00          callq  b <main+0xb>
                    7: R_X86_64_PC32        time-0x4
   b:       48 85 c0                test   %rax,%rax
   e:       74 11                   je     21 <main+0x21>
  10:       bf 00 00 00 00          mov    $0x0,%edi
                    11: R_X86_64_32 .rodata.str1.1+0x4
  15:       e8 00 00 00 00          callq  1a <main+0x1a>
                    16: R_X86_64_PC32       puts-0x4
  1a:       31 c0                   xor    %eax,%eax
  1c:       48 83 c4 08             add    $0x8,%rsp
  20:       c3                      retq
  21:       ba 01 00 00 00          mov    $0x1,%edx
  26:       be 00 00 00 00          mov    $0x0,%esi
                    27: R_X86_64_32 .rodata.str1.1
  2b:       bf 01 00 00 00          mov    $0x1,%edi
  30:       e8 00 00 00 00          callq  35 <main+0x35>
                    31: R_X86_64_PC32       __printf_chk-0x4
  35:       eb d9                   jmp    10 <main+0x10>

The printf (compiled to __printf_chk) was moved to the very end of the function, after puts and the return to improve branch prediction as mentioned by other answers.

So it is basically the same as:

int main() {
    int i = !time(NULL);
    if (i)
        goto printf;
puts:
    puts("a");
    return 0;
printf:
    printf("%d\n", i);
    goto puts;
}

This optimization was not done with -O0.

But good luck on writing an example that runs faster with __builtin_expect than without, CPUs are really smart these days. My naive attempts are here.

C++20 [[likely]] and [[unlikely]]

C++20 has standardized those C++ built-ins: How to use C++20's likely/unlikely attribute in if-else statement They will likely (a pun!) do the same thing.

It can be done multiple ways, continuing to edit this answer for spreading better knowledge perspective.

1) Reset hard

If you are working from remote develop branch, you can reset HEAD to the last commit on remote branch as below:

git reset --hard origin/develop

2) Delete current branch, and checkout again from the remote repository

Considering, you are working on develop branch in local repo, that syncs with remote/develop branch, you can do as below:

git branch -D develop
git checkout -b develop origin/develop

3) Abort Merge

If you are in-between a bad merge (mistakenly done with wrong branch), and wanted to avoid the merge to go back to the branch latest as below:

git merge --abort

4) Abort Rebase

If you are in-between a bad rebase, you can abort the rebase request as below:

git rebase --abort

You can do this by executing the following command:

ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012

gcc passes a few extra -L paths to the linker, which you can list with the following command:

gcc -print-search-dirs | sed '/^lib/b 1;d;:1;s,/[^/.][^/]*/\.\./,/,;t 1;s,:[^=]*=,:;,;s,;,;  ,g' | tr \; \\012

The answers suggesting to use ld.so.conf and ldconfig are not correct because they refer to the paths searched by the runtime dynamic linker (i.e. whenever a program is executed), which is not the same as the path searched by ld (i.e. whenever a program is linked).

Here's my webpack 4 + font awesome 5 solution:

webpack plugin:

new CopyWebpackPlugin([
    { from: 'node_modules/font-awesome/fonts', to: 'font-awesome' }
  ]),

global css style:

@font-face {
    font-family: 'FontAwesome';
    src: url('/font-awesome/fontawesome-webfont.eot');
    src: url('/font-awesome/fontawesome-webfont.eot?#iefix') format('embedded-opentype'),
    url('/font-awesome/fontawesome-webfont.woff2') format('woff2'),
    url('/font-awesome/fontawesome-webfont.woff') format('woff'),
    url('/font-awesome/fontawesome-webfont.ttf') format('truetype'),
    url('/font-awesome/fontawesome-webfont.svgfontawesomeregular') format('svg');
    font-weight: normal;
    font-style: normal;
}

i {
    font-family: "FontAwesome";
}

This error

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/bin/sh\": stat /bin/sh: no such file or directory": unknown.

occurs when creating a docker image from base image eg. scratch. This is because the resulting image does not have a shell to execute the image. If your use:

ENV EXECUTABLE hello
cmd [$EXECUTABLE]

in your docker file, docker uses /bin/sh to parse the input string. and hence the error. Inspecting on the image, your will find:

$docker inspect <image-name>
"Entrypoint": [
                "/bin/sh",
                "-c",
                "[$HM_APP]"
            ]

This means that the ENTRYPOINT or CMD arguments will be parsed using /bin/sh -c. The solution that worked for me is to parse the command as a JSON array of string e.g.

cmd ["hello"]

and inspecting the image again:

"Entrypoint": [
                "hello"
            ]

This removes the dependence on /bin/sh the docker app can now execute the binary file. Example:

FROM scratch

# Environmental variables

# Copy files
ADD . /
# Home dir
WORKDIR /bin

EXPOSE 8083
ENTRYPOINT ["hospitalms"]

Hope this helps someone in future.

Here is a sample code with explanation.

 //Create a response instance
 $response = new Illuminate\Http\Response('Hello World');

 //Call the withCookie() method with the response method
 $response->withCookie(cookie('name', 'value', $minutes));

 //return the response
 return $response;

Cookie can be set forever by using the forever method as shown in the below code.

$response->withCookie(cookie()->forever('name', 'value'));

Retrieving a Cookie

//’name’ is the name of the cookie to retrieve the value of
$value = $request->cookie('name');

I had the very same problem, and unfortunately it could not be solved by adding getter methods, or adding jackson dependencies.

I then looked at Official Spring Guide, and followed their example as given here - https://spring.io/guides/gs/actuator-service/ - where the example also shows the conversion of returned object to JSON format.

I then again made my own project, with the difference that this time I also added the dependencies and build plugins that's present in the pom.xml file of the Official Spring Guide example I mentioned above.

The modified dependencies and build part of XML file looks like this!

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

You can see the same in the mentioned link above.

And magically, atleast for me, it works. So, if you have already exhausted your other options, you might want to try this out, as was the case with me.

Just a side note, it didn't work for me when I added the dependencies in my previous project and did Maven install and update project stuff. So, I had to again make my project from scratch. I didn't bother much about it as mine is an example project, but you might want to look for that too!

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";

If Controls.Find is not found "textBox1" => error. You must add code.

If(tbx != null)

Edit:

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
If(tbx != null)
   tbx.Text = "found!";

This should get you started:

R> qplot(hwy, cty, data = mpg) + 
       facet_grid(. ~ manufacturer) + 
       theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

See also this question: How can I manipulate the strip text of facet plots in ggplot2?

Never hardcode sensitive information (account credentials, passwords, etc.). Instead, create a file to store that information as environment variables (key/value pairs), and exclude that file from your source code management system. For example, in terms of Git (source code management system), exclude that file by adding it to .gitignore:

-bash> echo '/config/app_environment_variables.rb' >> .gitignore 

/config/app_environment_variables.rb

ENV['HTTP_USER'] = 'devuser'
ENV['HTTP_PASS'] = 'devpass'

As well, add the following lines to /config/environment.rb, between the require line, and the Application.initialize line:

# Load the app's custom environment variables here, so that they are loaded before environments/*.rb
app_environment_variables = File.join(Rails.root, 'config', 'app_environment_variables.rb')
load(app_environment_variables) if File.exists?(app_environment_variables)

That's it!

As the comment above says, by doing this you will be loading your environment variables before environments/*.rb, which means that you will be able to refer to your variables inside those files (e.g. environments/production.rb). This is a great advantage over putting your environment variables file inside /config/initializers/.

Inside app_environment_variables.rb there's no need to distinguish environments as far as development or production because you will never commit this file into your source code management system, hence it is for the development context by default. But if you need to set something special for the test environment (or for occasions when you test production mode locally), just add a conditional block below all the other variables:

if Rails.env.test?
  ENV['HTTP_USER'] = 'testuser'
  ENV['HTTP_PASS'] = 'testpass'
end

if Rails.env.production?
  ENV['HTTP_USER'] = 'produser'
  ENV['HTTP_PASS'] = 'prodpass'
end

Whenever you update app_environment_variables.rb, restart the app server. Assuming you are using the likes of Apache/Passenger or rails server:

-bash> touch tmp/restart.txt

In your code, refer to the environment variables as follows:

def authenticate
  authenticate_or_request_with_http_basic do |username, password|
    username == ENV['HTTP_USER'] && password == ENV['HTTP_PASS']
  end
end

Note that inside app_environment_variables.rb you must specify booleans and numbers as strings (e.g. ENV['SEND_MAIL'] = 'false' not just false, and ENV['TIMEOUT'] = '30' not just 30), otherwise you will get the errors can't convert false into String and can't convert Fixnum into String, respectively.

Storing and sharing sensitive information

The final knot to tie is: how to share this sensitive information with your clients and/or partners? For the purpose of business continuity (i.e. when you get hit by a falling star, how will your clients and/or partners resume full operations of the site?), your clients and/or partners need to know all the credentials required by your app. Emailing/Skyping these things around is insecure and leads to disarray. Storing it in shared Google Docs is not bad (if everyone uses https), but an app dedicated to storing and sharing small titbits like passwords would be ideal.

How to set environment variables on Heroku

If you have a single environment on Heroku:

-bash> heroku config:add HTTP_USER='herouser'
-bash> heroku config:add HTTP_USER='heropass'

If you have multiple environments on Heroku:

-bash> heroku config:add HTTP_USER='staguser' --remote staging
-bash> heroku config:add HTTP_PASS='stagpass' --remote staging

-bash> heroku config:add HTTP_USER='produser' --remote production
-bash> heroku config:add HTTP_PASS='prodpass' --remote production

Foreman and .env

Many developers use Foreman (installed with the Heroku Toolbelt) to run their apps locally (as opposed to using the likes of Apache/Passenger or rails server). Foreman and Heroku use Procfile for declaring what commands are run by your application, so the transition from local dev to Heroku is seamless in that regard. I use Foreman and Heroku in every Rails project, so this convenience is great. But here's the thing.. Foreman loads environment variables stored in /.env via dotenv but unfortunately dotenv essentially only parses the file for key=value pairs; those pairs don't become variables right there and then, so you can't refer to already set variables (to keep things DRY), nor can you do "Ruby" in there (as noted above with the conditionals), which you can do in /config/app_environment_variables.rb. For instance, in terms of keeping things DRY I sometimes do stuff like this:

ENV['SUPPORT_EMAIL']='Company Support <[email protected]>'
ENV['MAILER_DEFAULT_FROM'] = ENV['SUPPORT_EMAIL']
ENV['MAILER_DEFAULT_TO']   = ENV['SUPPORT_EMAIL']

Hence, I use Foreman to run my apps locally, but I don't use its .env file for loading environment variables; rather I use Foreman in conjunction with the /config/app_environment_variables.rb approach described above.

sounds like you have the same problem i tried to solve here. in my case, it's a Linux fileserver (running samba, of course), so i can log in and see what process is locking the file; unfortunately, i haven't found how to close it without killing the responsible session. AFAICT, the windows client 'thinks' it's closed; but didn't bother telling the fileserver.

before I had not tried yet the code : in the following I post the version for the sql-code for both Klaus and user457226 solutions which worked on my pc [Postgres 8.3], with just some little adjustements for the Klaus one and of my version for the user457226 one.

I got same error everything was correct only i was using same statement interface object to execute and update the database. After separating i.e. using different objects of statement interface for updating and executing query i resolved this error. i.e. do get rid from this do not use same statement object for both updating and executing the query.

I think that you are looking for something like this:

   function rightclick() {
    var rightclick;
    var e = window.event;
    if (e.which) rightclick = (e.which == 3);
    else if (e.button) rightclick = (e.button == 2);
    alert(rightclick); // true or false, you can trap right click here by if comparison
}

(http://www.quirksmode.org/js/events_properties.html)

And then use the onmousedown even with the function rightclick() (if you want to use it globally on whole page you can do this <body onmousedown=rightclick(); >

This is a good description of its uses and shortcomings. You essentially use it whenever you need to do fast low-level I/O. If you were going to implement a TCP/IP protocol or if you were writing a database (DBMS) this class would come in handy.

The PDB file is typically used to store debug information. This warning is caused probably because the file vc80.pdb is not found when linking the target object file. Read the MSDN entry on LNK4099 here.

Alternatively, you can turn off debug information generation from the Project Properties > Linker > Debugging > Generate Debug Info field.

There is an option in WinSCP that does exactly what you are looking for:

The following statement causes a user's password to expire:

ALTER USER user PASSWORD EXPIRE;

If you cause a database user's password to expire with PASSWORD EXPIRE, then the user (or the DBA) must change the password before attempting to log in to the database following the expiration. Tools such as SQL*Plus allow the user to change the password on the first attempted login following the expiration.

ALTER USER scott IDENTIFIED BY password;

Will set/reset the users password.

See the alter user doc for more info

Mount your Windows partition with "exec" option - on some distros it's "noexec" by default.

Most of the solutions I see here seem to be doing a double measurement: first measuring the child views, and then calling the super.onMeasure()

I have come up with a custom WrapContentViewPager that is more efficient, works well with RecyclerView and Fragment

You can check the demo here:

github/ssynhtn/WrapContentViewPager

and the code of the class here: WrapContentViewPager.java

It could be something like that:

var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

var arrays = [], size = 3;
    
while (a.length > 0)
  arrays.push(a.splice(0, size));

console.log(arrays);

See splice Array's method.

The general theory can be found in wikipedia's article on Kademlia. The specific protocol specification used in bittorrent is here: http://wiki.theory.org/BitTorrentDraftDHTProtocol

Create and similar object for comparison works too ex:

from datetime import datetime, date

now = datetime.now()
today = date.today()

# compare now with today
two_month_earlier = date(now.year, now.month - 2, now.day)
if two_month_earlier > today:
    print(True)

two_month_earlier = datetime(now.year, now.month - 2, now.day)
if two_month_earlier > now:
   print("this will work with datetime too")

Guava now has an EvictingQueue, a non-blocking queue which automatically evicts elements from the head of the queue when attempting to add new elements onto the queue and it is full.

import java.util.Queue;
import com.google.common.collect.EvictingQueue;

Queue<Integer> fifo = EvictingQueue.create(2); 
fifo.add(1); 
fifo.add(2); 
fifo.add(3); 
System.out.println(fifo); 

// Observe the result: 
// [2, 3]

A reason can be duplicated libraries after importing from Eclipse IDE.

I had the same problem, after comment:

The app get no errors.

1. insert is not a recommended way - it is one of the ways to insert into map. The difference with operator[] is that the insert can tell whether the element is inserted into the map. Also, if your class has no default constructor, you are forced to use insert.
2. operator[] needs the default constructor because the map checks if the element exists. If it doesn't then it creates one using default constructor and returns a reference (or const reference to it).

Because map containers do not allow for duplicate key values, the insertion operation checks for each element inserted whether another element exists already in the container with the same key value, if so, the element is not inserted and its mapped value is not changed in any way.

This rule is intended to avoid conflicts in legacy code that still uses raw types.

Here's an illustration of why this was not allowed, drawn from the JLS. Suppose, before generics were introduced to Java, I wrote some code like this:

class CollectionConverter {
  List toList(Collection c) {...}
}

You extend my class, like this:

class Overrider extends CollectionConverter{
  List toList(Collection c) {...}
}

After the introduction of generics, I decided to update my library.

class CollectionConverter {
  <T> List<T> toList(Collection<T> c) {...}
}

You aren't ready to make any updates, so you leave your Overrider class alone. In order to correctly override the toList() method, the language designers decided that a raw type was "override-equivalent" to any generified type. This means that although your method signature is no longer formally equal to my superclass' signature, your method still overrides.

Now, time passes and you decide you are ready to update your class. But you screw up a little, and instead of editing the existing, raw toList() method, you add a new method like this:

class Overrider extends CollectionConverter {
  @Override
  List toList(Collection c) {...}
  @Override
  <T> List<T> toList(Collection<T> c) {...}
}

Because of the override equivalence of raw types, both methods are in a valid form to override the toList(Collection<T>) method. But of course, the compiler needs to resolve a single method. To eliminate this ambiguity, classes are not allowed to have multiple methods that are override-equivalent—that is, multiple methods with the same parameter types after erasure.

The key is that this is a language rule designed to maintain compatibility with old code using raw types. It is not a limitation required by the erasure of type parameters; because method resolution occurs at compile-time, adding generic types to the method identifier would have been sufficient.

    children: React.ReactNode

    );
}

Replace audio

ffmpeg -i video.mp4 -i audio.wav -map 0:v -map 1:a -c:v copy -shortest output.mp4

• The -map option allows you to manually select streams / tracks. See FFmpeg Wiki: Map for more info.
• This example uses -c:v copy to stream copy (mux) the video. No re-encoding of the video occurs. Quality is preserved and the process is fast.
  • If your input audio format is compatible with the output format then change -c:v copy to -c copy to stream copy both the video and audio.
  • If you want to re-encode video and audio then remove -c:v copy / -c copy.
• The -shortest option will make the output the same duration as the shortest input.

Add audio

ffmpeg -i video.mkv -i audio.mp3 -map 0 -map 1:a -c:v copy -shortest output.mkv

• The -map option allows you to manually select streams / tracks. See FFmpeg Wiki: Map for more info.
• This example uses -c:v copy to stream copy (mux) the video. No re-encoding of the video occurs. Quality is preserved and the process is fast.
  • If your input audio format is compatible with the output format then change -c:v copy to -c copy to stream copy both the video and audio.
  • If you want to re-encode video and audio then remove -c:v copy / -c copy.
• The -shortest option will make the output the same duration as the shortest input.

Mixing/combining two audio inputs into one

Use video from video.mkv. Mix audio from video.mkv and audio.m4a using the amerge filter:

ffmpeg -i video.mkv -i audio.m4a -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map 0:v -map "[a]" -c:v copy -ac 2 -shortest output.mkv

See FFmpeg Wiki: Audio Channels for more info.

Generate silent audio

You can use the anullsrc filter to make a silent audio stream. The filter allows you to choose the desired channel layout (mono, stereo, 5.1, etc) and the sample rate.

ffmpeg -i video.mp4 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 \
-c:v copy -shortest output.mp4

            connection.setRequestMethod("GET");
            connection.setDoOutput(true);
            InputStream content = (InputStream)connection.getInputStream();
            connection.getHeaderField("Content-Type");

            System.out.println("Content-Type "+ connection.getHeaderField("Content-Type"));

            BufferedReader in = new BufferedReader (new InputStreamReader(content));

}

If you're only getting these to manually pass into df.set_index(), that's unnecessary. Just directly do df.set_index['your_col_name', drop=False], already.

It's very rare in pandas that you need to get an index as a Python list (unless you're doing something pretty funky, or else passing them back to NumPy), so if you're doing this a lot, it's a code smell that you're doing something wrong.

Collection is a base interface for most collection classes (it is the root interface of java collection framework) Collections is a utility class

Collections class is a utility class having static methods It implements Polymorphic algorithms which operate on collections.

JS

 $(function () {
    var url = $(location).attr('href');
    $('#spn_url').html('<strong>' + url + '</strong>');
    $("#submit").click(function () {
        alert('button clicked');
    });
});

html

<input id="submit" type="submit" value="submit" name="submit">

You can assign "button" to role attribute of any html tag/element to make pointer over it. i.e

<html-element role="button" />

After a lot of trial and error I found this solved my problems. This is used to display photos on TVs via a browser.

• It Keeps the photos aspect ratio
• Scales in vertical and horizontal
• Centers vertically and horizontal

• The only thing to watch for are really wide images. They do stretch to fill, but not by much, standard camera photos are not altered.

Wrapping can be done in various ways. I'll mention 2 of them:

1.) text wrapping - using white-space property http://www.w3schools.com/cssref/pr_text_white-space.asp

2.) word wrapping - using word-wrap property http://webdesignerwall.com/tutorials/word-wrap-force-text-to-wrap

By the way, in order to work using these 2 approaches, I believe you need to set the "display" property to block of the corresponding span element.

However, as Kirill already mentioned, it's a good idea to think about it for a moment. You're talking about forcing the text into a paragraph. PARAGRAPH. That should ring some bells in your head, shouldn't it? ;)

It's because size_t can be anything other than an int (maybe a struct). The idea is that it decouples it's job from the underlying type.

Sometimes you need to grep the process by name - in that case:

ps aux | grep simple-scan

Example output:

simple-scan  1090  0.0  0.1   4248  1432 ?        S    Jun11   0:00

You can also pad a string to the required length using Guava's Strings.padEnd(String input, int minLength, char padding)

I have used new StackFrame(1).GetMethod().Name; in .net core 2.1 with dependency injection and I am getting calling method as 'Start'.

I tried with [System.Runtime.CompilerServices.CallerMemberName] string callerName = "" and it gives me correct calling method

Why not using: { position: fixed; bottom: 0 } ?

it works for me fine, if you a have string, then simply explode it first.

$emails = array();

Mail::send('emails.maintenance',$mail_params, function($message) use ($emails) {

ComputerDruid's answer is great but I don't think it's necessary to set upstream manually unless you want to. I'm adding this answer because people might think that that's a necessary step.

This error will be gone if you specify the remote that you want to pull like below:

git pull origin master

Note that origin is the name of the remote and master is the branch name.

1) How to check remote's name

git remote -v

2) How to see what branches available in the repository.

git branch -r

curl --write-out "%{http_code}\n" --silent --output /dev/null "$URL"

works. If not, you have to hit return to view the code itself.

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

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

And then access that value in the function

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

Intel now provides a Python distribution for Linux / Windows / OS X for free called "Intel distribution for Python".

Its a complete Python distribution (e.g. python.exe is included in the package) which includes some pre-installed modules compiled against Intel's MKL (Math Kernel Library) and thus optimized for faster performance.

The distribution includes the modules NumPy, SciPy, scikit-learn, pandas, matplotlib, Numba, tbb, pyDAAL, Jupyter, and others. The drawback is a bit of lateness in upgrading to more recent versions of Python. For example as of today (1 May 2017) the distribution provides CPython 3.5 while the 3.6 version is already out. But if you don't need the new features they should be perfectly fine.

Here's a regex-less approach I used for my own project.

If you are trying to detect HTML string among other non-HTML strings, you can convert to HTML parser object and then back and see if the string lengths are different. I.e.:

def isHTML(string):
    string1 = string[:]
    soup = BeautifulSoup(string, 'html.parser')  # Can use other HTML parser like etree
    string2 = soup.text

    if string1 != string2:
        return True
    elif string1 == string2:
        return False

It worked on my sample of 2800 strings.

You can change the labels' text by adorning the property with the DisplayName attribute.

[DisplayName("Someking Status")]
public string SomekingStatus { get; set; }

Or, you could write the raw HTML explicitly:

<label for="SomekingStatus" class="control-label">Someking Status</label>

you could use text files to trasfer the data using PHP and reading the text file in python

I got this to work by clearing the file input value onClick and then posting the file onChange. This allows the user to select the same file twice in a row and still have the change event fire to post to the server. My example uses the the jQuery form plugin.

$('input[type=file]').click(function(){
    $(this).attr("value", "");
})  
$('input[type=file]').change(function(){
    $('#my-form').ajaxSubmit(options);      
})

I will try to explain with a interesting and easy to understand example. :)

Assume that a organization organizes a chess tournament where 10 players (with equal chess playing skills) will challenge a professional champion chess player. And since chess is 1:1 game thus organizers have to conduct 10 games in time efficient manner so that they can finish the whole event as quickly as possible.

Hopefully following scenarios will easily describe multiple ways of conducting these 10 games:

1) SERIAL - lets say that the professional plays with each person one by one i.e. starts and finishes the game with one person and then starts the next game with next person and so on. In other words, they decided to conduct the games sequentially. So if one game takes 10 mins to complete then 10 games will take 100 mins, also assume that transition from one game to other takes 6 secs then for 10 games it will be 54 secs (approx. 1 min).

so the whole event will approximately complete in 101 mins (WORST APPROACH)

2) CONCURRENT - lets say that professional plays his turn and moves on to next player so all 10 players are playing simultaneously but the professional player is not with two person at a time, he plays his turn and moves on to next person. Now assume professional player takes 6 sec to play his turn and also transition time of professional player b/w two players is 6 sec so total transition time to get back to first player will be 1min (10x6sec). Therefore, by the time he is back to first person with, whom event was started, 2mins have passed (10xtime_per_turn_by_champion + 10xtransition_time=2mins)

Assuming that all player take 45sec to complete their turn so based on 10mins per game from SERIAL event the no. of rounds before a game finishes should 600/(45+6) = 11 rounds (approx)

So the whole event will approximately complete in 11xtime_per_turn_by_player_&_champion + 11xtransition_time_across_10_players = 11x51 + 11x60sec= 561 + 660 = 1221sec = 20.35mins (approximately)

SEE THE IMPROVEMENT from 101 mins to 20.35 mins (BETTER APPROACH)

3) PARALLEL - lets say organizers get some extra funds and thus decided to invite two professional champion player (both equally capable) and divided the set of same 10 players (challengers) in two group of 5 each and assigned them to two champion i.e. one group each. Now the event is progressing in parallel in these two sets i.e. at least two players (one in each group) are playing against the two professional players in their respective group.

However within the group the professional player with take one player at a time (i.e. sequentially) so without any calculation you can easily deduce that whole event will approximately complete in 101/2=50.5mins to complete

SEE THE IMPROVEMENT from 101 mins to 50.5 mins (GOOD APPROACH)

4) CONCURRENT + PARALLEL - In above scenario, lets say that the two champion player will play concurrently (read 2nd point) with the 5 players in their respective groups so now games across groups are running in parallel but within group they are running concurrently.

So the games in one group will approximately complete in 11xtime_per_turn_by_player_&_champion + 11xtransition_time_across_5_players = 11x51 + 11x30 = 600 + 330 = 930sec = 15.5mins (approximately)

So the whole event (involving two such parallel running group) will approximately complete in 15.5mins

SEE THE IMPROVEMENT from 101 mins to 15.5 mins (BEST APPROACH)

NOTE: in above scenario if you replace 10 players with 10 similar jobs and two professional player with a two CPU cores then again the following ordering will remain true:

SERIAL > PARALLEL > CONCURRENT > CONCURRENT+PARALLEL

(NOTE: this order might change for other scenarios as this ordering highly depends on inter-dependency of jobs, communication needs b/w jobs and transition overhead b/w jobs)

As some people have mentioned, Javascript is the way to go. Bear in mind that the "validation" here is only by file extension, it won't validate that the file is a real excel spreadsheet!

You can also set up a mime type for application/JavaScript to run as PHP, .NET, Java, or whatever language you're using. I've done this for dynamic CSS files in the past.

Consider thttpd. It can run under windows.

Quoting wikipedia:

"it is uniquely suited to service high volume requests for static data"

A version of thttpd-2.25b compiled under cygwin with cygwin dll's is available. It is single threaded and particularly good for servicing images.

The problem you face is that you try to assign the return of imshow (which is an matplotlib.image.AxesImage to an existing axes object.

The correct way of plotting image data to the different axes in axarr would be

f, axarr = plt.subplots(2,2)
axarr[0,0].imshow(image_datas[0])
axarr[0,1].imshow(image_datas[1])
axarr[1,0].imshow(image_datas[2])
axarr[1,1].imshow(image_datas[3])

The concept is the same for all subplots, and in most cases the axes instance provide the same methods than the pyplot (plt) interface. E.g. if ax is one of your subplot axes, for plotting a normal line plot you'd use ax.plot(..) instead of plt.plot(). This can actually be found exactly in the source from the page you link to.

Having had a similar problem with data from 1800 to now, this worked for me:

data2$date=as.character(data2$date) 
lct <- Sys.getlocale("LC_TIME"); 
Sys.setlocale("LC_TIME","C")
data2$date<- as.Date(data2$date, format = "%Y %m %d") # and it works

I know this is a bit late - but to be clear:

A string doesn't really have encoding... in .NET the a string is a collection of char objects. Essentially, if it is a string, it has already been decoded.

However if you are reading the contents of a file, which is made of bytes, and wish to convert that to a string, then the file's encoding must be used.

.NET includes encoding and decoding classes for: ASCII, UTF7, UTF8, UTF32 and more.

Most of these encodings contain certain byte-order marks that can be used to distinguish which encoding type was used.

The .NET class System.IO.StreamReader is able to determine the encoding used within a stream, by reading those byte-order marks;

Here is an example:

    /// <summary>
    /// return the detected encoding and the contents of the file.
    /// </summary>
    /// <param name="fileName"></param>
    /// <param name="contents"></param>
    /// <returns></returns>
    public static Encoding DetectEncoding(String fileName, out String contents)
    {
        // open the file with the stream-reader:
        using (StreamReader reader = new StreamReader(fileName, true))
        {
            // read the contents of the file into a string
            contents = reader.ReadToEnd();

            // return the encoding.
            return reader.CurrentEncoding;
        }
    }

one of the easy way to do that is use landa function without any problem like

userControl_Material1.simpleButton4.Click += (s, ee) =>
            {
                Save_mat(mat_global);
            };

Check out James Padolsey's animateToSelector

Intro: This jQuery plugin will allow you to animate any element to styles specified in your stylesheet. All you have to do is pass a selector and the plugin will look for that selector in your StyleSheet and will then apply it as an animation.

I think that this below is accurate and it may help. Feel free to correct it if you find any errors. I'm new at C.

char str[]  

1. array of values of type char, with its own address in memory
2. array of values of type char, with its own address in memory as many consecutive addresses as elements in the array

3. including termination null character '\0' &str, &str[0] and str, all three represent the same location in memory which is address of the first element of the array str

   char *strPtr = &str[0]; //declaration and initialization

alternatively, you can split this in two:

char *strPtr; strPtr = &str[0];

4. strPtr is a pointer to a char
5. strPtr points at array str
6. strPtr is a variable with its own address in memory
7. strPtr is a variable that stores value of address &str[0]
8. strPtr own address in memory is different from the memory address that it stores (address of array in memory a.k.a &str[0])
9. &strPtr represents the address of strPtr itself

I think that you could declare a pointer to a pointer as:

char **vPtr = &strPtr;  

declares and initializes with address of strPtr pointer

Alternatively you could split in two:

char **vPtr;
*vPtr = &strPtr

10. *vPtr points at strPtr pointer
11. *vPtr is a variable with its own address in memory
12. *vPtr is a variable that stores value of address &strPtr
13. final comment: you can not do str++, str address is a const, but you can do strPtr++

$(document).ready(function() {
  $('#div_one').bind('click', function() {
    $('#div_two').addClass('large');
  });
});

If I understood your question.

Or you can modify css directly:

var $speech = $('div.speech');
var currentSize = $speech.css('fontSize');
$speech.css('fontSize', '10px');

Access is a great multi-user database. It has lots of built in features to handle the multi-user situation. In fact, it is so very popular because it is such a great multi-user database. There is an upper limit on how many users can all use the database at the same time doing updates and edits - depending on how knowledgeable the developer is about access and how the database has been designed - anywhere from 20 users to approx 50 users. Some access databases can be built to handle up to 50 concurrent users, while many others can handle 20 or 25 concurrent users updating the database. These figures have been observed for databases that have been in use for several or more years and have been discussed many times on the access newsgroups.

A while back, I wrote about this in Cross Browser Background Transparency With CSS.

Bizarrely Internet Explorer 6 will allow you to make the background transparent and keep the text on top fully opaque. For the other browsers I then suggest using a transparent PNG file.

.has() seems to be designed for this purpose. Since it returns a jQuery object, you have to test for .length as well:

if ($('div#hello').has(target).length) {
   alert('Target is a child of #hello');
}

You can use -j.

-j
--junk-paths
          Store just the name of a saved file (junk the path), and do  not
          store  directory names. By default, zip will store the full path
          (relative to the current directory).

I use some css like this (based on css tricks):

@media screen and (min-width: 320px) and (max-width: 767px) and (orientation: portrait) {
  html {
    transform: rotate(-90deg);
    transform-origin: left top;
    width: 100vh;
    height: 100vw;
    overflow-x: hidden;
    position: absolute;
    top: 100%;
    left: 0;
  }
}

Because in 2nd case you adding same reference twice and HashSet have check against this in HashMap.put() on which HashSet is based:

        if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
            V oldValue = e.value;
            e.value = value;
            e.recordAccess(this);
            return oldValue;
        }

As you can see, equals will be called only if hash of key being added equals to the key already present in set and references of these two are different.

//for update

(from x in dataBase.Customers
         where x.Name == "Test"
         select x).ToList().ForEach(xx => xx.Name="New Name");

//for delete

dataBase.Customers.RemoveAll(x=>x.Name=="Name");

I just want to add to what's been said so far, it may save a lot of headache, you don't need to wait 24 hour to see if it works, yes the total overview take 24 hour, but in Reporting tab, there is a link on left side to Real-Time result and it will show if anyone currently visiting your site, also I didn't have to set 'cookieDomain': 'none' for it to work on localhost, my setting is on 'auto' and it works just fine (I'm using MVC 5), on top of that I've added the script at the end of head tag as google stated in this page:

Paste your snippet (unaltered, in its entirety) into every web page you want to track. Paste it immediately before the closing </head> tag.

here is more info on how to check to see if analytics works properly.

You have to use func setTitleColor(_ color: UIColor?, for state: UIControlState) the same way you set the actual title text. Docs

isbeauty.setTitleColor(UIColorFromRGB("F21B3F"), for: .normal)

you have done it the correct way using

curl_setopt($ch, CURLOPT_POSTFIELDS,$body);

but i notice your missing

curl_setopt($ch, CURLOPT_POST,1);

There are two solutions in mysql:

A) Delete duplicate rows using DELETE JOIN statement

DELETE t1 FROM contacts t1
INNER JOIN contacts t2 
WHERE 
    t1.id < t2.id AND 
    t1.email = t2.email;

This query references the contacts table twice, therefore, it uses the table alias t1 and t2.

The output is:

1 Query OK, 4 rows affected (0.10 sec)

In case you want to delete duplicate rows and keep the lowest id, you can use the following statement:

DELETE c1 FROM contacts c1
INNER JOIN contacts c2 
WHERE
    c1.id > c2.id AND 
    c1.email = c2.email;

B) Delete duplicate rows using an intermediate table

The following shows the steps for removing duplicate rows using an intermediate table:

    1. Create a new table with the structure the same as the original table that you want to delete duplicate rows.

    2. Insert distinct rows from the original table to the immediate table.

    3. Insert distinct rows from the original table to the immediate table.

Step 1. Create a new table whose structure is the same as the original table:

CREATE TABLE source_copy LIKE source;

Step 2. Insert distinct rows from the original table to the new table:

INSERT INTO source_copy
SELECT * FROM source
GROUP BY col; -- column that has duplicate values

Step 3. drop the original table and rename the immediate table to the original one

DROP TABLE source;
ALTER TABLE source_copy RENAME TO source;

Source: http://www.mysqltutorial.org/mysql-delete-duplicate-rows/

You can use an enhanced for loop:

Set<String> set = new HashSet<String>();

//populate set

for (String s : set) {
    System.out.println(s);
}

Or with Java 8:

set.forEach(System.out::println);

In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.

I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?

Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,

There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.

The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).

Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.

Here is how I solved the issue, might be useful to some:

Ajax modal doesn't seem to be available with boostrap 2.1.1

So I ended up coding it myself:

$('[data-toggle="modal"]').click(function(e) {
  e.preventDefault();
  var url = $(this).attr('href');
  //var modal_id = $(this).attr('data-target');
  $.get(url, function(data) {
      $(data).modal();
  });
});

Example of a link that calls a modal:

<a href="{{ path('ajax_get_messages', { 'superCategoryID': 6, 'sex': sex }) }}" data-toggle="modal">
    <img src="{{ asset('bundles/yopyourownpoet/images/messageCategories/BirthdaysAnniversaries.png') }}" alt="Birthdays" height="120" width="109"/>
</a>

I now send the whole modal markup through ajax.

This is an example of a very rare occasion where it is recommended to use == instead of ===. Expression somevar == null will return true for undefined and null, but false for everything else (an error if variable is undeclared).

Using the != will flip the result, as expected.

Modern editors will not warn for using == or != operator with null, as this is almost always the desired behavior.

Most common comparisions:

undeffinedVar == null     // true
obj.undefinedProp == null // true
null == null              // true
0 == null                 // false
'0' == null               // false
'' == null                // false

Try it yourself:

let undefinedVar;
console.table([
    { test : undefinedVar,     result: undefinedVar     == null },
    { test : {}.undefinedProp, result: {}.undefinedProp == null },
    { test : null,             result: null             == null },
    { test : false,            result: false            == null },
    { test : 0,                result: 0                == null },
    { test : '',               result: ''               == null },
    { test : '0',              result: '0'              == null },
]);

For a faster NLTK-based solution you could hash the set of words to avoid a linear search.

from nltk.corpus import words as nltk_words
def is_english_word(word):
    # creation of this dictionary would be done outside of 
    #     the function because you only need to do it once.
    dictionary = dict.fromkeys(nltk_words.words(), None)
    try:
        x = dictionary[word]
        return True
    except KeyError:
        return False

this worked best for me:

        Cells(partcount + 5, "N").Value = Date + Time
        Cells(partcount + 5, "N").NumberFormat = "mm/dd/yy hh:mm:ss AM/PM"

• You don't need the eq matcher if you don't use other matchers.
• You are not using the correct syntax - your method call should be outside the .verify(mock). You are now initiating verification on the result of the method call, without verifying anything (not making a method call). Hence all tests are passing.

You code should look like:

Mockito.verify(mock).mymethod(obj);
Mockito.verify(mock).mymethod(null);
Mockito.verify(mock).mymethod("something_else");

Just in case any Windows users are having trouble, I thought I'd add my own experience. When running python manage.py runserver 0.0.0.0:8000, I could view urls using localhost:8000, but not my ip address 192.168.1.3:8000.

I ended up disabling ipv6 on my wireless adapter, and running ipconfig /renew. After this everything worked as expected.

Eclipse Java EE IDE for Web Developers.

Version: Neon.3 Release (4.6.3) Build id: 20170314-1500

The fix/trick for me was deleting my local repository in ~/.m2/repository in order to remove local dependencies and rebuilding my project in which fresh dependencies are pulled down.

You can have $(document).ready() multiple times in a page. The code gets run in the sequence in which it appears.

You can use the $(window).load() event for your code since this happens after the page is fully loaded and all the code in the various $(document).ready() handlers have finished running.

$(window).load(function(){
  //your code here
});

to make it easier for you here is the code that i use :

w, h = image.shape
top=10
right=50
down=15
left=80
croped_image = image[top:((w-down)+top), right:((h-left)+right)]
plt.imshow(croped_image, cmap="gray")
plt.show()

This is a function that I use. Created it once so I always have this functionality:

function getDir(){
    $directory = dirname(__FILE__);
    $directory = explode("/",$directory);
    $findTarget = 0;
    $targetPath = "";
    foreach($directory as $dir){
        if($findTarget == 1){
            $targetPath = "".$targetPath."/".$dir."";
        }
        if($dir == "public_html"){
            $findTarget = 1;
        }
    }
    return "http://www.".$_SERVER['SERVER_NAME']."".$targetPath."";
}

This should work for you. If you are using SPA.

app.use('/', express.static(path.join(__dirname, 'your folder')));
// Send all other requests to the SPA
app.get('*', (req, res) => {
    res.sendFile(path.join(__dirname, 'your folder/index.html'));
});

InitialValue="0" : initial validation will fire when 0th index item is selected in ddl.

<asp:RequiredFieldValidator InitialValue="0" Display="Dynamic" CssClass="error" runat="server" ID="your_id" ValidationGroup="validationgroup" ControlToValidate="your_dropdownlist_id" />

I see no proof that it is not good practice. Yes, it may look like a mistake but that is easily remedied by judicious commenting. Take for instance:

if (x = processorIntensiveFunction()) { // declaration inside if intended
    alert(x);
}

Why should that function be allowed to run a 2nd time with:

alert(processorIntensiveFunction());

Because the first version LOOKS bad? I cannot agree with that logic.

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

You need to pass the whole point to location

var point = new Point(50, 100);
this.balancePanel.Location = point;

You can remove the duplicate elements with the uniq method:

array.uniq  # => [1, 2, 4, 5, 6, 7, 8]

What might also be useful to know is that uniq takes a block, so if you have a have an array of keys:

["bucket1:file1", "bucket2:file1", "bucket3:file2", "bucket4:file2"]

and you want to know what the unique files are, you can find it out with:

a.uniq { |f| f[/\d+$/] }.map { |p| p.split(':').last }

go

Usage:

declare @liststr varchar(max)
select @liststr = dbo.group_concat_d(institutionname, ',')
from education
where studentnumber = '111'
group by studentnumber;
select @liststr

GroupConcat does not support ordering, though. You could use PIVOT, CTE's and windows functions if you need ordering:

drop table if exists #students;
create table #students (
    name        varchar(20),
    institution varchar(20),
    year        int -- order by year
)
go

insert into #students(name, institution, year)
values
    ('Simon', 'INSTITUTION1', 2005),
    ('Simon', 'INSTITUTION2', 2008);

with cte as (
    select name,
           institution,
           rn = row_number() over (partition by name order by year)
    from #students
)
select name,
       [1] +
       isnull((',' + [2]), '') +
       isnull((',' + [3]), '') +
       isnull((',' + [4]), '') +
       isnull((',' + [5]), '') +
       isnull((',' + [6]), '') +
       isnull((',' + [7]), '') +
       isnull((',' + [8]), '') +
       isnull((',' + [9]), '') +
       isnull((',' + [10]), '') +
       isnull((',' + [11]), '') +
       isnull((',' + [12]), '') +
       isnull((',' + [13]), '') +
       isnull((',' + [14]), '') +
       isnull((',' + [15]), '') +
       isnull((',' + [16]), '') +
       isnull((',' + [17]), '') +
       isnull((',' + [18]), '') +
       isnull((',' + [19]), '') +
       isnull((',' + [20]), '')
from cte
    pivot (
    max(institution)
    for rn in ([1], [2], [3], [4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20])
    ) as piv

Here is a way to do it that works, but may not be best practise for any language really:

var x,y;
x='something';
y=1;
undefined === y || (x = y);

alternatively

undefined !== y && (x = y);

First, you'll need to tell git about yourself. Get your username and token together from your settings page.

Then run:

git config --global github.user YOUR_USERNAME
git config --global github.token YOURTOKEN

You will need to generate a new key if you don't have a back-up of your key.

Then you should be able to run:

git clone [email protected]:YOUR_USERNAME/YOUR_PROJECT.git

If you want to add new value='newValue' and text='newLabel', you should add this code:

1. Add new Option to <select>:

   var opt = "<option value='newValue' selected ='selected'>" + newLabel+ " </option>";
   $(selLocationID).html(opt);
   

2. Trigger <select> change to selected value:

   $(selLocationID).val('newValue').trigger("change");
   

In my case the error was some old username and password was stored in cache.

So I removed it by going to sourceTree and delete the existing account.

Now for the new clone then it will ask you for the password for the repo.

in the package.json write { "type": "module" }

it fixed my problem, I had the same problem

In my situation this helped:

Before proceeding to execute these commands close all VS Code instances.

1. clean cache with

    npm cache clean --force
   

2. install the latest version of npm globally as admin:

    npm install -g npm@latest --force
   

3. clean cache with

    npm cache clean --force
   

4. Try to install your component once again.

I hope this works for others, if not you may also try temporarily disabling antivirus software before trying again.

You used the egg files install procedure. This procedure supports installing over git, git+http, git+https, git+ssh, git+git and git+file. Some of these are mentioned.

It's good you can use branches, tags, or hashes to install.

@Steve_K noted it can be slow to install with "git+" and proposed installing via zip file:

pip install https://github.com/user/repository/archive/branch.zip

Alternatively, I suggest you may install using the .whl file if this exists.

pip install https://github.com/user/repository/archive/branch.whl

It's pretty new format, newer than egg files. It requires wheel and setuptools>=0.8 packages. You can find more in here.

From PEP 8 - Style Guide for Python Code:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. Make sure to indent the continued line appropriately.

Example of implicit line continuation:

a = some_function(
    '1' + '2' + '3' - '4')

On the topic of line-breaks around a binary operator, it goes on to say:-

For decades the recommended style was to break after binary operators. But this can hurt readability in two ways: the operators tend to get scattered across different columns on the screen, and each operator is moved away from its operand and onto the previous line.

In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. For new code Knuth's style (line breaks before the operator) is suggested.

Example of explicit line continuation:

a = '1'   \
    + '2' \
    + '3' \
    - '4'

I see all the answers mention when object slicing happens when data members are sliced. Here I give an example that the methods are not overridden:

class A{
public:
    virtual void Say(){
        std::cout<<"I am A"<<std::endl;
    }
};

class B: public A{
public:
    void Say() override{
        std::cout<<"I am B"<<std::endl;
    }
};

int main(){
   B b;
   A a1;
   A a2=b;

   b.Say(); // I am B
   a1.Say(); // I am A
   a2.Say(); // I am A   why???
}

B (object b) is derived from A (object a1 and a2). b and a1, as we expect, call their member function. But from polymorphism viewpoint we don’t expect a2, which is assigned by b, to not be overridden. Basically, a2 only saves A-class part of b and that is object slicing in C++.

To solve this problem, a reference or pointer should be used

 A& a2=b;
 a2.Say(); // I am B

or

A* a2 = &b;
a2->Say(); // I am B

Try closing and reopening the file, then press Ctrl+F11.

Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.

Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.

You can also by jquery:

$('#foo')[0].disabled = true;

Working example:

$('#foo')[0].disabled = true;

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<input id="foo" placeholder="placeholder" value="value" />
