Inspired by the accepted answer by @ford04 I had even better approach dealing with it, instead of using useEffect inside useAsync create a new function that returns a callback for componentWillUnmount :

function asyncRequest(asyncRequest, onSuccess, onError, onComplete) {
  let isMounted=true
  asyncRequest().then((data => isMounted ? onSuccess(data):null)).catch(onError).finally(onComplete)
  return () => {isMounted=false}
}

...

useEffect(()=>{
        return asyncRequest(()=>someAsyncTask(arg), response=> {
            setSomeState(response)
        },onError, onComplete)
    },[])

This issue is due to incompatible of your plugin Verison and required Gradle version; they need to match with each other. I am sharing how my problem was solved.

plugin version

Required Gradle version is here

more compatibility you can see from here. Android Plugin for Gradle Release Notes

if you have the android studio version 4.0.1

then your top level gradle file must be like this

buildscript {
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.2'
    classpath 'com.google.firebase:firebase-crashlytics-gradle:2.4.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

and the gradle version should be

and your app gradle look like this

Use the map-function instead. It transforms the value inside the optional.

Like this:

private String getStringIfObjectIsPresent(Optional<Object> object) {
    return object.map(() -> {
        String result = "result";
        //some logic with result and return it
        return result;
    }).orElseThrow(MyCustomException::new);
}

Use kafka-consumer-groups.sh

For example

bin/kafka-consumer-groups.sh  --list --bootstrap-server localhost:9092

bin/kafka-consumer-groups.sh --describe --group mygroup --bootstrap-server localhost:9092

For REST controllers, I would recommend to use Zalando Problem Spring Web.

https://github.com/zalando/problem-spring-web

If Spring Boot aims to embed some auto-configuration, this library does more for exception handling. You just need to add the dependency:

<dependency>
    <groupId>org.zalando</groupId>
    <artifactId>problem-spring-web</artifactId>
    <version>LATEST</version>
</dependency>

And then define one or more advice traits for your exceptions (or use those provided by default)

public interface NotAcceptableAdviceTrait extends AdviceTrait {

    @ExceptionHandler
    default ResponseEntity<Problem> handleMediaTypeNotAcceptable(
            final HttpMediaTypeNotAcceptableException exception,
            final NativeWebRequest request) {
        return Responses.create(Status.NOT_ACCEPTABLE, exception, request);
    }

}

Then you can defined the controller advice for exception handling as:

@ControllerAdvice
class ExceptionHandling implements MethodNotAllowedAdviceTrait, NotAcceptableAdviceTrait {

}

Apache Kafka command to get un handled messages on all partitions of a topic:

kafka-run-class kafka.tools.ConsumerOffsetChecker 
    --topic test --zookeeper localhost:2181 
    --group test_group

Prints:

Group      Topic        Pid Offset          logSize         Lag             Owner
test_group test         0   11051           11053           2               none
test_group test         1   10810           10812           2               none
test_group test         2   11027           11028           1               none

Column 6 is the un-handled messages. Add them up like this:

kafka-run-class kafka.tools.ConsumerOffsetChecker 
    --topic test --zookeeper localhost:2181 
    --group test_group 2>/dev/null | awk 'NR>1 {sum += $6} 
    END {print sum}'

awk reads the rows, skips the header line and adds up the 6th column and at the end prints the sum.

Prints

5

One more reason for this error (assuming that gradle properly setup) is incompatibility between andorid.gradle tools and gradle itself - check out this answer for the complete compatibility table.

In my case the error was the same as in the question and the stacktrace as following:

java.lang.NullPointerException

    ...

I've fixed that by upgrading com.android.tools.build:gradle to the current latest 3.1.4

buildscript {
    repositories {
        ...
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
    }
}

Gradle version is 4.6

I recently ran into the same problem but the issue wasn't related to tabs and spaces but an odd Unicode character that appeared invisible to the eye in my IDE. Eventually, I isolated the problem and typed out the line exactly as it was and checked the git diff:

If you are able to isolate the line before the reported line and type it out again, you might find that it solves your problem. Won't tell you why it happened in the first place, but it at least gets rid of the issue.

Don't know how you want to format it, but you can do:

print("Created at %s:%s" % (t1.hour, t1.minute))

for example.

I encountered another problem that returns the same error.

Single quote issue

I used a json string with single quotes :

{
    'property': 1
}

But json.loads accepts only double quotes for json properties :

{
    "property": 1
}

Final comma issue

json.loads doesn't accept a final comma:

{
  "property": "text", 
  "property2": "text2",
}

Solution: ast to solve single quote and final comma issues

You can use ast (part of standard library for both Python 2 and 3) for this processing. Here is an example :

import ast
# ast.literal_eval() return a dict object, we must use json.dumps to get JSON string
import json

# Single quote to double with ast.literal_eval()
json_data = "{'property': 'text'}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}

# ast.literal_eval() with double quotes
json_data = '{"property": "text"}'
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}

# ast.literal_eval() with final coma
json_data = "{'property': 'text', 'property2': 'text2',}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property2": "text2", "property": "text"}

Using ast will prevent you from single quote and final comma issues by interpet the JSON like Python dictionnary (so you must follow the Python dictionnary syntax). It's a pretty good and safely alternative of eval() function for literal structures.

Python documentation warned us of using large/complex string :

Warning It is possible to crash the Python interpreter with a sufficiently large/complex string due to stack depth limitations in Python’s AST compiler.

json.dumps with single quotes

To use json.dumps with single quotes easily you can use this code:

import ast
import json

data = json.dumps(ast.literal_eval(json_data_single_quote))

ast documentation

ast Python 3 doc

ast Python 2 doc

Tool

If you frequently edit JSON, you may use CodeBeautify. It helps you to fix syntax error and minify/beautify JSON.

I hope it helps.

Building on what is mentioned in the comments, the simplest solution would be:

@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {

    //whatever

}

class SomeDto {

   private List<WhateverBudgerPerDateDTO> budgetPerDate;


  //getters setters
}

The solution assumes that the HTTP request you are creating actually has

Content-Type:application/json instead of text/plain

Use flatMap. If a value is present, flatMap returns a sequential Stream containing only that value, otherwise returns an empty Stream. So there is no need to use ifPresent() . Example:

list.stream().map(data -> data.getSomeValue).map(this::getOptinalValue).flatMap(Optional::stream).collect(Collectors.toList());

This is a solution but in form of my story with this problem:

I was almost dead trying all the solution given above(for 3 days ) and nothing worked for me.

I lost all hope.

I contacted my security team regarding this because i was behind a proxy and they told that they had recently updated their security policy.

I scolded them badly for not informing the Developers.

Later they issued a new "cacerts" file which contains all the certificates.

I removed the cacerts file which is present inside %JAVA_HOME%/jre/lib/security and it solved my problem.

So if you are facing this issue it might be from your network team also like this.

I am facing this problem many times from last few days, the answer above works perfectly fine. I was looking for the exact reason for this problem and in my case I found slow internet or no internet on your machine(assuming you are taking project to windows from mac, that may not be required).

I've noticed while doing build it stopped fetching a URL(http://.maven.org/). I don't know why android studio doing these things again, but that seems to be the only problem in my case.

You need to adjust three (or four) properties:

• Consumer side:fetch.message.max.bytes - this will determine the largest size of a message that can be fetched by the consumer.
• Broker side: replica.fetch.max.bytes - this will allow for the replicas in the brokers to send messages within the cluster and make sure the messages are replicated correctly. If this is too small, then the message will never be replicated, and therefore, the consumer will never see the message because the message will never be committed (fully replicated).
• Broker side: message.max.bytes - this is the largest size of the message that can be received by the broker from a producer.
• Broker side (per topic): max.message.bytes - this is the largest size of the message the broker will allow to be appended to the topic. This size is validated pre-compression. (Defaults to broker's message.max.bytes.)

I found out the hard way about number 2 - you don't get ANY exceptions, messages, or warnings from Kafka, so be sure to consider this when you are sending large messages.

Based on the stacktrace, an intuit class com.intuit.ipp.aggcat.util.SAML2AssertionGenerator needs a saml jar on the classpath.

A saml class org.opensaml.xml.XMLConfigurator needs on it's turn log4j, which is inside the WAR but cannot find it.

One explanation for this is that the class XMLConfigurator that needs log4j was found not inside the WAR but on a downstream classloader. could a saml jar be missing from the WAR?

The class XMLConfigurator that needs log4j cannot find it at the level of the classloader that loaded it, and the log4j version on the WAR is not visible on that particular classloader.

In order to troubleshoot this, a way is to add this before the oauth call:

System.out.println("all versions of log4j Logger: " + getClass().getClassLoader().getResources("org/apache/log4j/Logger.class") );

System.out.println("all versions of XMLConfigurator: " + getClass().getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );

System.out.println("all versions of XMLConfigurator visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );

System.out.println("all versions of log4j visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassloader().getResources("org/apache/log4j/Logger.class") );

Also if you are using Java 7, have a look at jHades, it's a tool I made to help troubleshooting these type of problems.

In order to see what is going on, could you post the results of the classpath queries above, for which container is this happening, tomcat, jetty? It would be better to put the full stacktrace with all the caused by's in pastebin, just in case.

This error means that, while linking, compiler is not able to find the definition of main() function anywhere.

In your makefile, the main rule will expand to something like this.

main: producer.o consumer.o AddRemove.o
   gcc -pthread -Wall -o producer.o consumer.o AddRemove.o

As per the gcc manual page, the use of -o switch is as below

-o file     Place output in file file. This applies regardless to whatever sort of output is being produced, whether it be an executable file, an object file, an assembler file or preprocessed C code. If -o is not specified, the default is to put an executable file in a.out.

It means, gcc will put the output in the filename provided immediate next to -o switch. So, here instead of linking all the .o files together and creating the binary [main, in your case], its creating the binary as producer.o, linking the other .o files. Please correct that.

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

In java 8 you can use List.forEach() method with lambda expression to iterate over a list.

import java.util.ArrayList;
import java.util.List;

public class TestA {
    public static void main(String[] args) {
        List<String> list = new ArrayList<String>();
        list.add("Apple");
        list.add("Orange");
        list.add("Banana");
        list.forEach(
                (name) -> {
                    System.out.println(name);
                }
        );
    }
}

In manually deleting a topic from a kafka cluster , you just might check this out https://github.com/darrenfu/bigdata/issues/6 A vital step missed a lot in most solution is in deleting the /config/topics/<topic_name> in ZK.

You aren't actually sending JSON. You are passing an object as the data, but you need to stringify the object and pass the string instead.

Your dataType: "json" only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.

Change to:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify({
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        }),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
});

After fiddling around with @journois's answer, I was able to get it to work using MultiIndex instead of Panel due to Panel's deprication.

First, create some dummy data:

df1 = pd.DataFrame({
    'id': ['111', '222', '333', '444', '555'],
    'let': ['a', 'b', 'c', 'd', 'e'],
    'num': ['1', '2', '3', '4', '5']
})
df2 = pd.DataFrame({
    'id': ['111', '222', '333', '444', '666'],
    'let': ['a', 'b', 'c', 'D', 'f'],
    'num': ['1', '2', 'Three', '4', '6'],
})

Then, define your diff function, in this case I'll use the one from his answer report_diff stays the same:

def report_diff(x):
    return x[0] if x[0] == x[1] else '{} | {}'.format(*x)

Then, I'm going to concatenate the data into a MultiIndex dataframe:

df_all = pd.concat(
    [df1.set_index('id'), df2.set_index('id')], 
    axis='columns', 
    keys=['df1', 'df2'],
    join='outer'
)
df_all = df_all.swaplevel(axis='columns')[df1.columns[1:]]

And finally I'm going to apply the report_diff down each column group:

df_final.groupby(level=0, axis=1).apply(lambda frame: frame.apply(report_diff, axis=1))

This outputs:

         let        num
111        a          1
222        b          2
333        c  3 | Three
444    d | D          4
555  e | nan    5 | nan
666  nan | f    nan | 6

And that is all!

WSDL: Stands for Web Service Description Language

In SOAP(simple object access protocol), when you use web service and add a web service to your project, your client application(s) doesn't know about web service Functions. Nowadays it's somehow old-fashion and for each kind of different client you have to implement different WSDL files. For example you cannot use same file for .Net and php client. The WSDL file has some descriptions about web service functions. The type of this file is XML. SOAP is an alternative for REST.

REST: Stands for Representational State Transfer

It is another kind of API service, it is really easy to use for clients. They do not need to have special file extension like WSDL files. The CRUD operation can be implemented by different HTTP Verbs(GET for Reading, POST for Creation, PUT or PATCH for Updating and DELETE for Deleting the desired document) , They are based on HTTP protocol and most of times the response is in JSON or XML format. On the other hand the client application have to exactly call the related HTTP Verb via exact parameters names and types. Due to not having special file for definition, like WSDL, it is a manually job using the endpoint. But it is not a big deal because now we have a lot of plugins for different IDEs to generating the client-side implementation.

SOA: Stands for Service Oriented Architecture

Includes all of the programming with web services concepts and architecture. Imagine that you want to implement a large-scale application. One practice can be having some different services, called micro-services and the whole application mechanism would be calling needed web service at the right time. Both REST and SOAP web services are kind of SOA.

JSON: Stands for javascript Object Notation

when you serialize an object for javascript the type of object format is JSON. imagine that you have the human class :

class Human{
 string Name;
 string Family;
 int Age;
}

and you have some instances from this class :

Human h1 = new Human(){
  Name='Saman',
  Family='Gholami',
  Age=26
}

when you serialize the h1 object to JSON the result is :

  [h1:{Name:'saman',Family:'Gholami',Age:'26'}, ...]

javascript can evaluate this format by eval() function and make an associative array from this JSON string. This one is different concept in comparison to other concepts I described formerly.

If your datasets are between 1 and 20GB, you should get a workstation with 48GB of RAM. Then Pandas can hold the entire dataset in RAM. I know its not the answer you're looking for here, but doing scientific computing on a notebook with 4GB of RAM isn't reasonable.

If you've got pagination you also sort the data by some key. Why not let API clients include the key of the last element of the previously returned collection in the URL and add a WHERE clause to your SQL query (or something equivalent, if you're not using SQL) so that it returns only those elements for which the key is greater than this value?

ReSTful APIs are consumed primarily by other systems, which is why I put paging data in the response headers. However, some API consumers may not have direct access to the response headers, or may be building a UX over your API, so providing a way to retrieve (on demand) the metadata in the JSON response is a plus.

I believe your implementation should include machine-readable metadata as a default, and human-readable metadata when requested. The human-readable metadata could be returned with every request if you like or, preferably, on-demand via a query parameter, such as include=metadata or include_metadata=true.

In your particular scenario, I would include the URI for each product with the record. This makes it easy for the API consumer to create links to the individual products. I would also set some reasonable expectations as per the limits of my paging requests. Implementing and documenting default settings for page size is an acceptable practice. For example, GitHub's API sets the default page size to 30 records with a maximum of 100, plus sets a rate limit on the number of times you can query the API. If your API has a default page size, then the query string can just specify the page index.

In the human-readable scenario, when navigating to /products?page=5&per_page=20&include=metadata, the response could be:

{
  "_metadata": 
  {
      "page": 5,
      "per_page": 20,
      "page_count": 20,
      "total_count": 521,
      "Links": [
        {"self": "/products?page=5&per_page=20"},
        {"first": "/products?page=0&per_page=20"},
        {"previous": "/products?page=4&per_page=20"},
        {"next": "/products?page=6&per_page=20"},
        {"last": "/products?page=26&per_page=20"},
      ]
  },
  "records": [
    {
      "id": 1,
      "name": "Widget #1",
      "uri": "/products/1"
    },
    {
      "id": 2,
      "name": "Widget #2",
      "uri": "/products/2"
    },
    {
      "id": 3,
      "name": "Widget #3",
      "uri": "/products/3"
    }
  ]
}

For machine-readable metadata, I would add Link headers to the response:

Link: </products?page=5&perPage=20>;rel=self,</products?page=0&perPage=20>;rel=first,</products?page=4&perPage=20>;rel=previous,</products?page=6&perPage=20>;rel=next,</products?page=26&perPage=20>;rel=last

(the Link header value should be urlencoded)

...and possibly a custom total-count response header, if you so choose:

total-count: 521

The other paging data revealed in the human-centric metadata might be superfluous for machine-centric metadata, as the link headers let me know which page I am on and the number per page, and I can quickly retrieve the number of records in the array. Therefore, I would probably only create a header for the total count. You can always change your mind later and add more metadata.

As an aside, you may notice I removed /index from your URI. A generally accepted convention is to have your ReST endpoint expose collections. Having /index at the end muddies that up slightly.

These are just a few things I like to have when consuming/creating an API. Hope that helps!

You can still use the Authorization header with OAuth 2.0. There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.

It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1

E.g.:

   GET /resource HTTP/1.1
   Host: server.example.com
   Authorization: Bearer mF_9.B5f-4.1JqM

Where mF_9.B5f-4.1JqM is your OAuth access token.

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data

WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.

SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON

This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.

With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.

It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.

Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.

• For more details regarding control information I highly recommend to read this: http://www.amundsen.com/hypermedia/hfactor/
• Web Linking: http://tools.ietf.org/html/rfc5988
• Registered link relations: http://www.iana.org/assignments/link-relations/link-relations.xml

REST is over only HTTP

Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.

P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284

RabbitMQ / AMQP: single queue, multiple consumers for same message and page refresh.

rabbit.on('ready', function () {    });
    sockjs_chat.on('connection', function (conn) {

        conn.on('data', function (message) {
            try {
                var obj = JSON.parse(message.replace(/\r/g, '').replace(/\n/g, ''));

                if (obj.header == "register") {

                    // Connect to RabbitMQ
                    try {

I had the issue with PeriodicTask classes in django-celery, while their names showed up fine when starting the celery worker every execution triggered:

KeyError: u'my_app.tasks.run'

My task was a class named 'CleanUp', not just a method called 'run'.

When I checked table 'djcelery_periodictask' I saw outdated entries and deleting them fixed the issue.

My solution,

load the app using

NODE_ENV=production node app.js

Then setup config.js as a function rather than an object

module.exports = function(){
    switch(process.env.NODE_ENV){
        case 'development':
            return {dev setting};

        case 'production':
            return {prod settings};

        default:
            return {error or other settings};
    }
};

Then as per Jans solution load the file and create a new instance which we could pass in a value if needed, in this case process.env.NODE_ENV is global so not needed.

var Config = require('./conf'),
    conf = new Config();

Then we can access the config object properties exactly as before

conf.twitter.consumerKey

From the documentation on http://curl.haxx.se/docs/httpscripting.html :

HTTP Authentication

curl --user name:password http://www.example.com 

Put a file to a HTTP server with curl:

curl --upload-file uploadfile http://www.example.com/receive.cgi

Send post data with curl:

curl --data "birthyear=1905&press=%20OK%20" http://www.example.com/when.cgi

var full = location.protocol+'//'+location.hostname+(location.port ? ':'+location.port: '');

This solved my issue,

I noticed that when using the Apache http client configuration with a pooling manager, the accepted answer doesn't work.

In this case it appears that the ClientConfig.sslContext and ClientConfig.hostnameVerifier setters are silently ignored. So if you are using connection pooling with the apache client http client config, you should be able to use the following code to get ssl verification to be ignored:

  ClientConfig clientConfig = new ClientConfig();
  // ... configure your clientConfig
  SSLContext sslContext = null;
  try {
    sslContext = SSLContext.getInstance("SSL");
    sslContext.init(null, new TrustManager[] {
        new X509TrustManager() {
          @Override
          public void checkClientTrusted(X509Certificate[] x509Certificates, String s) {
          }

          @Override
          public void checkServerTrusted(X509Certificate[] x509Certificates, String s) {
          }

          @Override
          public X509Certificate[] getAcceptedIssuers() {
            return new X509Certificate[] {};
          }
        }
    }, null);
  } catch (NoSuchAlgorithmException e) {
    //logger.debug("Ignoring 'NoSuchAlgorithmException' while ignoring ssl certificate validation.");
  } catch (KeyManagementException e) {
    //logger.debug("Ignoring 'KeyManagementException' while ignoring ssl certificate validation.");
  }
  Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
      .register("http", PlainConnectionSocketFactory.getSocketFactory())
      .register("https", new SSLConnectionSocketFactory(sslContext, new AbstractVerifier() {
        @Override
        public void verify(String host, String[] cns, String[] subjectAlts) {
        }
      }))
      .build();
  connectionManager = new PoolingHttpClientConnectionManager(socketFactoryRegistry);
  clientConfig.property(ApacheClientProperties.CONNECTION_MANAGER, connectionManager);
  return ClientBuilder.newClient(clientConfig);

If boolean() is not available (the tool I'm using does not) one way to achieve it is:

//SELECT[@id='xpto']/OPTION[not(not(@selected))]

In this case, within the /OPTION, one of the options is the selected one. The "selected" does not have a value... it just exists, while the other OPTION do not have "selected". This achieves the objective.

Queue is JMS managed object used for holding messages waiting for subscribers to consume. When all subscribers consumed the message , message will be removed from queue.

Topic is that all subscribers to a topic receive the same message when the message is published.

When using this approach you have to make sure that none of your values contains something that would be illegal XML – user1151923

I always use the XML method. Make sure you use VALID XML. I have two functions to convert between valid XML and Text. (I tend to strip out the carriage returns as I don't usually need them.

CREATE FUNCTION dbo.udf_ConvertTextToXML (@Text varchar(MAX)) 
    RETURNS varchar(MAX)

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

Yes there is 2MB max and it can be increased by configuration change like this. If your POST body is not in form of multipart file then you might need to add the max-http-post configuration for tomcat in the application yml configuration file.

Increase max size of each multipart file to 10MB and total payload size of 100MB max

 spring:
    servlet:
      multipart:max-file-size: 10MB
      multipart:max-request-size: 100MB
 

Setting max size of post requests which might just be the formdata in string format to ~10 MB

 server:
    tomcat:
        max-http-post-size: 100000000 # max-http-form-post-size: 10MB for new version

You might need to add this for the latest sprintboot version ->

server: tomcat: max-http-form-post-size: 10MB

The PECS "rule" just ensures that the following is legal:

• Consumer: whatever ? is, it can legally refer to T
• Producer: whatever ? is, it can legally be referred to by T

The typical pairing along the lines of List<? extends T> producer, List<? super T> consumer is simply ensuring that the compiler can enforce the standard "IS-A" inheritance relationship rules. If we could do so legally, it might be simpler to say <T extends ?>, <? extends T> (or better yet in Scala, as you can see above, it's [-T], [+T]. Unfortunately the best we can do is <? super T>, <? extends T>.

When I first encountered this and broke it down in my head the mechanics made sense but the code itself continued to look confusing to me - I kept thinking "it seems like the bounds shouldn't need to be inverted like that" - even though I was clear on the above - that it's simply about guaranteeing compliance with the standard rules of reference.

What helped me was looking at it using ordinary assignment as an analogy.

Consider the following (not production ready) toy code:

// copies the elements of 'producer' into 'consumer'
static <T> void copy(List<? extends T> producer, List<? super T> consumer) {
   for(T t : producer)
       consumer.add(t);
}

Illustrating this in terms of the assignment analogy, for consumer the ? wildcard (unknown type) is the reference - the "left hand side" of the assignment - and <? super T> ensures that whatever ? is, T "IS-A" ? - that T can be assigned to it, because ? is a super type (or at most the same type) as T.

For producer the concern is the same it's just inverted: producer's ? wildcard (unknown type) is the referent - the "right hand side" of the assignment - and <? extends T> ensures that whatever ? is, ? "IS-A" T - that it can be assigned to a T, because ? is a sub type (or at least the same type) as T.

Java 5+ has all the tools you need for this kind of thing. You will want to:

1. Put all your Producers in one ExecutorService;
2. Put all your Consumers in another ExecutorService;
3. If necessary, communicate between the two using a BlockingQueue.

I say "if necessary" for (3) because from my experience it's an unnecessary step. All you do is submit new tasks to the consumer executor service. So:

final ExecutorService producers = Executors.newFixedThreadPool(100);
final ExecutorService consumers = Executors.newFixedThreadPool(100);
while (/* has more work */) {
  producers.submit(...);
}
producers.shutdown();
producers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
consumers.shutdown();
consumers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);

So the producers submit directly to consumers.

My 2 cent. Same but different...

Let me at least answer a part of your question. With an example of how the Linux ABI affects the systemcalls, and why that is usefull.

A systemcall is a way for a userspace program to ask the kernelspace for something. It works by putting the numeric code for the call and the argument in a certain register and triggering an interrupt. Than a switch occurs to kernelspace and the kernel looks up the numeric code and the argument, handles the request, puts the result back into a register and triggers a switch back to userspace. This is needed for example when the application wants to allocate memory or open a file (syscalls "brk" and "open").

Now the syscalls have short names "brk", etc. and corresponding opcodes, these are defined in a system specific header file. As long as these opcodes stay the same you can run the same compiled userland programs with different updated kernels without having to recompile. So you have an interface used by precompiled binarys, hence ABI.

If you need something like:

  ¦ A                              ¦ B
--+--------------------------------+---
1 ¦ #My comment, something else    ¦
2 ¦ 1                              ¦ 2

Your CSV may contain the following lines:

"#My comment, something else"
1,2

Pay close attention at the 'quotes' in the first line.

When converting your text to columns using the Excel wizard, remember checking the 'Treat consecutive delimiters as one', setting it to use 'quotes' as delimiter.

Thus, Excel will split the text at the commas, keeping the 'comment' line as a single column value (and it will remove the quotes).

I believe the first appearance of iterators and generators were in the Icon programming language, about 20 years ago.

You may enjoy the Icon overview, which lets you wrap your head around them without concentrating on the syntax (since Icon is a language you probably don't know, and Griswold was explaining the benefits of his language to people coming from other languages).

After reading just a few paragraphs there, the utility of generators and iterators might become more apparent.

ConcurrentLinkedQueue is lock-free, LinkedBlockingQueue is not. Every time you invoke LinkedBlockingQueue.put() or LinkedBlockingQueue.take(), you need acquire the lock first. In other word, LinkedBlockingQueue has poor concurrency. If you care performance, try ConcurrentLinkedQueue + LockSupport.

This is largely a duplicate of another question.

Here's the section of that answer that is relevant to this question:

Do I need to do my own synchronization if I use java.util.ConcurrentLinkedQueue?

Atomic operations on the concurrent collections are synchronized for you. In other words, each individual call to the queue is guaranteed thread-safe without any action on your part. What is not guaranteed thread-safe are any operations you perform on the collection that are non-atomic.

For example, this is threadsafe without any action on your part:

queue.add(obj);

or

queue.poll(obj);

However; non-atomic calls to the queue are not automatically thread-safe. For example, the following operations are not automatically threadsafe:

if(!queue.isEmpty()) {
   queue.poll(obj);
}

That last one is not threadsafe, as it is very possible that between the time isEmpty is called and the time poll is called, other threads will have added or removed items from the queue. The threadsafe way to perform this is like this:

synchronized(queue) {
    if(!queue.isEmpty()) {
       queue.poll(obj);
    }
}

Again...atomic calls to the queue are automatically thread-safe. Non-atomic calls are not.

I'm thinking unload is called all but at hard exist in 4.7. But, if you are playing around with older versions of .Net, try doing this in your loading method:

e.Handled = true;

I don't think older versions will unload until loading is handled. Just posting because I see others still asking this question, and haven't seen this proposed as a solution. I only touch .Net a few times a year, and ran into this a few years back. But, I wonder if it's as simple as unload not being called until loading has finished. Seems like it works for me, but again in newer .Net it seems to always call unload even if loading isn't marked as handled.

Much of the value of PEP-8 is to stop people arguing about inconsequential formatting rules, and get on with writing good, consistently formatted code. Sure, no one really thinks that 79 is optimal, but there's no obvious gain in changing it to 99 or 119 or whatever your preferred line length is. I think the choices are these: follow the rule and find a worthwhile cause to battle for, or provide some data that demonstrates how readability and productivity vary with line length. The latter would be extremely interesting, and would have a good chance of changing people's minds I think.

  document.getElementById(container).innerHTML = '';

minimumFontSize has been deprecated with iOS 6. You can use minimumScaleFactor.

yourLabel.adjustsFontSizeToFitWidth=YES;
yourLabel.minimumScaleFactor=0.5;

This will take care of your font size according width of label and text.

If you have the same method name in two different classes and you just want to run one of them, this works:

pytest tests.py -k 'TestClassName and test_method_name'

With Internet Explorer you often have to specify the Pragma: public header as well for the download to function properly..

header('Pragma: public');

Just my 2 cents..

Updated with a proper plugin

I have published a proper plugin for the dropdown hover functionality, in which you can even define what happens when clicking on the dropdown-toggle element:

https://github.com/istvan-ujjmeszaros/bootstrap-dropdown-hover

Why I made it, when there are many solutions already?

I had issues with all the previously existing solutions. The simple CSS ones are not using the .open class on the .dropdown, so there will be no feedback on the dropdown toggle element when the dropdown is visible.

The js ones are interfering with clicking on .dropdown-toggle, so the dropdown shows up on hover, then hides it when clicking on an opened dropdown, and moving out the mouse will trigger the dropdown to show up again. Some of the js solutions are braking iOS compatibility, some plugins are not working on modern desktop browsers which are supporting the touch events.

That's why I made the Bootstrap Dropdown Hover plugin which prevents all these issues by using only the standard Bootstrap javascript API, without any hack.

To get the base URL you can use this (would return "http:// localhost/yiistore2/upload")

Yii::app()->baseUrl

The following Code would return just "localhost/yiistore2/upload" without http[s]://

Yii::app()->getBaseUrl(true)

Or you could get the webroot path (would return "d:\wamp\www\yii2store")

Yii::getPathOfAlias('webroot')

System variables can be set through CMD and registry For ex. reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATH

All the commonly used CMD codes and system variables are given here: Set Windows system environment variables using CMD.

Open CMD and type Set

You will get all the values of system variable.

Type set java to know the path details of java installed on your window OS.

Not sure if you are coding these programs, but this is a simple example of how you'd do it.

program1.c

#include <stdio.h>
int main (int argc, char * argv[] ) {
    printf("%s", argv[1]); 
    return 0;
}

rgx.cpp

#include <cstdio>
#include <regex>
#include <iostream>
using namespace std;
int main (int argc, char * argv[] ) {
    char input[200];
    fgets(input,200,stdin);
    string s(input)
    smatch m;
    string reg_exp(argv[1]);
    regex e(reg_exp);
    while (regex_search (s,m,e)) {
      for (auto x:m) cout << x << " ";
      cout << endl;
      s = m.suffix().str();
    }
    return 0;
}

Compile both then run program1.exe "this subject has a submarine as a subsequence" | rgx.exe "\b(sub)([^ ]*)"

The | operator simply redirects the output of program1's printf operation from the stdout stream to the stdin stream whereby it's sitting there waiting for rgx.exe to pick up.

Configuring this worked for me: -vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m on Eclipse Java Photon June 2018

Running Windows 10, 8 GB ram and 64 bit. You can extend -Xmx2048 -XX:MaxpermSize= 1024m to 4096m too, if your computer has good ram.Mine worked well.

method 1 using ChildRef:

public childRef: any = React.createRef<Hello>();

public onButtonClick= () => {
    console.log(this.childRef.current); // this will have your child reference
}

<Hello ref = { this.childRef }/>
<button onclick="onButtonClick()">Click me!</button>

Method 2: using window register

public onButtonClick= () => {
    console.log(window.yourRef); // this will have your child reference
}

<Hello ref = { (ref) => {window.yourRef = ref} }/>`
<button onclick="onButtonClick()">Click me!</button>

For me the solutions of this Error very strange. It was the issue of port address of EndpointAddress. In Visual studio port address of your file (e.g. Service1.svc) and port address of your wcf project must be the same which you gives into EndpointAddress. Let me describe you this solution in detail.

There are two steps to check the port addresses.

1. In your WCF Project right click to your Service file (e.g. Service1.svc) -> than select View in browser now in your browser you have url like http://localhost:61122/Service1.svc so now note down your port address as a 61122

2. Righ click your wcf project -> than select Properties -> go to the Web Tab -> Now in Servers section -> select Use Visual Studio Development Server -> select Specific Port and give the port address which we have earlier find from our Service1.svc service. That is (61122).

Earlier I have different port address. After Specifying port address properly which I have given into EndpointAddress, my problem was solved.

I hope this might be solved your issue.

Environment returns user data directory. And getFilesDir returns application data directory.

This is where you can find the answer in the job-dsl-plugin code.

Basically you can do something like this:

readFileFromWorkspace('src/main/groovy/com/groovy/jenkins/scripts/enable_safehtml.groovy')

My problem was with x64 compilations deployed to a remote testing machine. I found the x64 versions of msvp120d.dll and msvcr120d.dll in

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\redist\Debug_NonRedist\x64\Microsoft.VC120.DebugCRT

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

Here's a simple example with no jQuery. Use URL.createObjectURL, which

creates a DOMString containing a URL representing the object given in the parameter

Then, you can simply set the src of the image to that url:

window.addEventListener('load', function() {
  document.querySelector('input[type="file"]').addEventListener('change', function() {
      if (this.files && this.files[0]) {
          var img = document.querySelector('img');
          img.onload = () => {
              URL.revokeObjectURL(img.src);  // no longer needed, free memory
          }

          img.src = URL.createObjectURL(this.files[0]); // set src to blob url
      }
  });
});

<input type='file' />
<br><img id="myImg" src="#">

if you want to select column with specific name then just do

A=mtcars[,which(conames(mtcars)==cols[1])]
#and then
colnames(mtcars)[A]=cols[1]

you can run it in loop as well reverse way to add dynamic name eg if A is data frame and xyz is column to be named as x then I do like this

A$tmp=xyz
colnames(A)[colnames(A)=="tmp"]=x

again this can also be added in loop

Yes, use INSERT ... ON DUPLICATE KEY UPDATE id=id (it won't trigger row update even though id is assigned to itself).

If you don't care about errors (conversion errors, foreign key errors) and autoincrement field exhaustion (it's incremented even if the row is not inserted due to duplicate key), then use INSERT IGNORE.

The following are some comparisons:

String s1 = "Hello";
String s2 = "Hello";
String s3 = new String("Hello");

System.out.println(s1 == s2); //true
System.out.println(s1.equals(s2)); //true

System.out.println(s1 == s3);   //false
System.out.println(s1.equals(s3)); //true

s3 = s3.intern();
System.out.println(s1 == s3); //true
System.out.println(s1.equals(s3)); //true

When intern() is called the reference is changed.

tl;dr: (try it here)

If you have the following HTML:

<div id="menu" style="display: none;">
   <!-- menu stuff in here -->
   <ul><li>Menu item</li></ul>
</div>

<div class="parent">Hover over me to show the menu here</div>

then you can use the following JavaScript code:

$(".parent").mouseover(function() {
    // .position() uses position relative to the offset parent, 
    var pos = $(this).position();

    // .outerWidth() takes into account border and padding.
    var width = $(this).outerWidth();

    //show the menu directly over the placeholder
    $("#menu").css({
        position: "absolute",
        top: pos.top + "px",
        left: (pos.left + width) + "px"
    }).show();
});

But it doesn't work!

This will work as long as the menu and the placeholder have the same offset parent. If they don't, and you don't have nested CSS rules that care where in the DOM the #menu element is, use:

$(this).append($("#menu"));

just before the line that positions the #menu element.

But it still doesn't work!

You might have some weird layout that doesn't work with this approach. In that case, just use jQuery.ui's position plugin (as mentioned in an answer below), which handles every conceivable eventuality. Note that you'll have to show() the menu element before calling position({...}); the plugin can't position hidden elements.

Update notes 3 years later in 2012:

(The original solution is archived here for posterity)

So, it turns out that the original method I had here was far from ideal. In particular, it would fail if:

• the menu's offset parent is not the placeholder's offset parent
• the placeholder has a border/padding

Luckily, jQuery introduced methods (position() and outerWidth()) way back in 1.2.6 that make finding the right values in the latter case here a lot easier. For the former case, appending the menu element to the placeholder works (but will break CSS rules based on nesting).

This is the simple answer I can give.

I've simplified clone45 steps:

Open the ports as he mentioned

sudo su
sudo yum install vsftpd
echo -n "Public IP of your instance: " && read publicip
echo -e "anonymous_enable=NO\npasv_enable=YES\npasv_min_port=1024\npasv_max_port=1048\npasv_address=$publicip\nchroot_local_user=YES" >> /etc/vsftpd/vsftpd.conf
sudo /etc/init.d/vsftpd restart

• You don't need constructors
• You don't need to annotate inner classes
• RefreshScope have some problems when using with @Configuration. Please see this github issue

Change your class like this:

@ConfigurationProperties(prefix = "available-payment-channels-list")
@Configuration
public class AvailableChannelsConfiguration {

    private String xyz;
    private List<ChannelConfiguration> channelConfigurations;

    // getters, setters

    public static class ChannelConfiguration {
        private String name;
        private String companyBankAccount;

        // getters, setters
    }

}

This will match one or more alphabetical characters:

/^[a-z]+$/

You can make it case insensitive using:

/^[a-z]+$/i

or:

/^[a-zA-Z]+$/

If I understood correct,You need to set time zone first like:

date_default_timezone_set('UTC');

And than you can use date function:

// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');

All u need is just use one of the attribute of CSS , which is---->

cursor:pointer

just use this property in css , no matter its inline or internal or external

for example(for inline css)

<form>
<input type="submit" style= "cursor:pointer" value="Button" name="Button">
</form>

This should display the image inline:

.content-dir-item img.mail {
    display: inline-block;
    *display: inline; /* for older IE */
    *zoom: 1; /* for older IE */
}

I got the similar compiler error. Once I add the dependent project of the dll file to the solution, issue resolved.

The answer by @ajcr explains how the dot and matmul (invoked by the @ symbol) differ. By looking at a simple example, one clearly sees how the two behave differently when operating on 'stacks of matricies' or tensors.

To clarify the differences take a 4x4 array and return the dot product and matmul product with a 3x4x2 'stack of matricies' or tensor.

import numpy as np
fourbyfour = np.array([
                       [1,2,3,4],
                       [3,2,1,4],
                       [5,4,6,7],
                       [11,12,13,14]
                      ])


threebyfourbytwo = np.array([
                             [[2,3],[11,9],[32,21],[28,17]],
                             [[2,3],[1,9],[3,21],[28,7]],
                             [[2,3],[1,9],[3,21],[28,7]],
                            ])

print('4x4*3x4x2 dot:\n {}\n'.format(np.dot(fourbyfour,threebyfourbytwo)))
print('4x4*3x4x2 matmul:\n {}\n'.format(np.matmul(fourbyfour,threebyfourbytwo)))

The products of each operation appear below. Notice how the dot product is,

...a sum product over the last axis of a and the second-to-last of b

and how the matrix product is formed by broadcasting the matrix together.

4x4*3x4x2 dot:
 [[[232 152]
  [125 112]
  [125 112]]

 [[172 116]
  [123  76]
  [123  76]]

 [[442 296]
  [228 226]
  [228 226]]

 [[962 652]
  [465 512]
  [465 512]]]

4x4*3x4x2 matmul:
 [[[232 152]
  [172 116]
  [442 296]
  [962 652]]

 [[125 112]
  [123  76]
  [228 226]
  [465 512]]

 [[125 112]
  [123  76]
  [228 226]
  [465 512]]]

Maybe someone can help clarify why but if you're attempting to hit props to find location from a fresh install of Create React App on the App.js page you get:

TypeError: Cannot read property 'search' of undefined

Even though I have App.js as the home route:

<Route exact path='/' render={props => (

On App.js only, using window.location worked for me:

import queryString from 'query-string';
...
const queryStringParams = queryString.parse(window.location.search);

Use encodeURIComponent() to encode the string.

Eg. var myEscapedJSONString = encodeURIComponent(JSON.stringify(myJSON));

You don't need to decode it since the web server automatically do the same.

Keep in mind that the copy constructor limits the class type to that of the copy constructor. Consider the example:

// Need to clone person, which is type Person
Person clone = new Person(person);

This doesn't work if person could be a subclass of Person (or if Person is an interface). This is the whole point of clone, is that it can can clone the proper type dynamically at runtime (assuming clone is properly implemented).

Person clone = (Person)person.clone();

or

Person clone = (Person)SomeCloneUtil.clone(person); // See Bozho's answer

Now person can be any type of Person assuming that clone is properly implemented.

This is what I have so far. It covers both 1 and 3. I'm however still struggling with 2 since I'm not that familiar with Prototype (I'm more a jQuery type of guy).

function isVisible( elem ) {
    var $elem = $(elem);

    // First check if elem is hidden through css as this is not very costly:
    if ($elem.getStyle('display') == 'none' || $elem.getStyle('visibility') == 'hidden' ) {
        //elem is set through CSS stylesheet or inline to invisible
        return false;
    }

    //Now check for the elem being outside of the viewport
    var $elemOffset = $elem.viewportOffset();
    if ($elemOffset.left < 0 || $elemOffset.top < 0) {
        //elem is left of or above viewport
        return false;
    }
    var vp = document.viewport.getDimensions();
    if ($elemOffset.left > vp.width || $elemOffset.top > vp.height) {
        //elem is below or right of vp
        return false;
    }

    //Now check for elements positioned on top:
    //TODO: Build check for this using Prototype...
    //Neither of these was true, so the elem was visible:
    return true;
}

Use the command as

java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>

The above command will set the mentioned paths to classpath only once for executing the class named TestClass.

If you want to execute more then one classes, then you can follow this

set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"

After this you can execute as many classes as you want just by simply typing

java <your-class-name>

The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)

If you want to set the classpth only once so that it could work for everytime, then do as follows

1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
    a.  Variable Name-     classpath
    b.  Variable Value-    .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.

Remember this will work every time. You don't need to explicitly set the classpath again and again.

NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.

Hope this will help you.

Non-blocking, multi-threaded example:

As blocking on keyboard input (since the input() function blocks) is frequently not what we want to do (we'd frequently like to keep doing other stuff), here's a very-stripped-down multi-threaded example to demonstrate how to keep running your main application while still reading in keyboard inputs whenever they arrive.

This works by creating one thread to run in the background, continually calling input() and then passing any data it receives to a queue.

In this way, your main thread is left to do anything it wants, receiving the keyboard input data from the first thread whenever there is something in the queue.

1. Bare Python 3 code example (no comments):

import threading
import queue
import time

def read_kbd_input(inputQueue):
    print('Ready for keyboard input:')
    while (True):
        input_str = input()
        inputQueue.put(input_str)

def main():
    EXIT_COMMAND = "exit"
    inputQueue = queue.Queue()

    inputThread = threading.Thread(target=read_kbd_input, args=(inputQueue,), daemon=True)
    inputThread.start()

    while (True):
        if (inputQueue.qsize() > 0):
            input_str = inputQueue.get()
            print("input_str = {}".format(input_str))

            if (input_str == EXIT_COMMAND):
                print("Exiting serial terminal.")
                break
            
            # Insert your code here to do whatever you want with the input_str.

        # The rest of your program goes here.

        time.sleep(0.01) 
    print("End.")

if (__name__ == '__main__'): 
    main()

The Python Queue library is thread-safe:

Note that Queue.put() and Queue.get() and other Queue class methods are thread-safe! That means they implement all the internal locking semantics required for inter-thread operations, so each function call in the queue class can be considered as a single, atomic operation. See the notes at the top of the documentation: https://docs.python.org/3/library/queue.html (emphasis added):

The queue module implements multi-producer, multi-consumer queues. It is especially useful in threaded programming when information must be exchanged safely between multiple threads. The Queue class in this module implements all the required locking semantics.

I agree with previous opinions. It is good to say, that if you are going to share DbContext in single thread app, you'll need more memory. For example my web application on Azure (one extra small instance) needs another 150 MB of memory and I have about 30 users per hour.

Here is real example image: application have been deployed in 12PM

While it is possible to combine the results, I would advise against doing so.

You have two fundamentally different types of queries that return a different number of rows, a different number of columns and different types of data. It would be best to leave it as it is - two separate queries.

create or replace procedure point_triangle
AS
BEGIN
FOR thisteam in (select FIRSTNAME,LASTNAME,SUM(PTS)  from PLAYERREGULARSEASON  where TEAM    = 'IND' group by FIRSTNAME, LASTNAME order by SUM(PTS) DESC)

LOOP
dbms_output.put_line(thisteam.FIRSTNAME|| ' ' || thisteam.LASTNAME || ':' || thisteam.PTS);
END LOOP;

END;
/

Alternatively, you could use tensorflow for the cropping and openCV for making an array from the image.

import cv2
img = cv2.imread('YOURIMAGE.png')

Now img is a (imageheight, imagewidth, 3) shape array. Crop the array with tensorflow:

import tensorflow as tf
offset_height=0
offset_width=0
target_height=500
target_width=500
x = tf.image.crop_to_bounding_box(
    img, offset_height, offset_width, target_height, target_width
)

Reassemble the image with tf.keras, so we can look at it if it worked:

tf.keras.preprocessing.image.array_to_img(
    x, data_format=None, scale=True, dtype=None
)

This prints out the pic in a notebook (tested in Google Colab).

The whole code together:

import cv2
img = cv2.imread('YOURIMAGE.png')

import tensorflow as tf
offset_height=0
offset_width=0
target_height=500
target_width=500
x = tf.image.crop_to_bounding_box(
    img, offset_height, offset_width, target_height, target_width
)

tf.keras.preprocessing.image.array_to_img(
    x, data_format=None, scale=True, dtype=None
)

With moment you can parse the date string you have:

var dt = moment(myDate.date, "YYYY-MM-DD HH:mm:ss")

That's for UTC, you'll have to convert the time zone from that point if you so desire.

Then you can get the day of the week:

dt.format('dddd');

(function( $ ) {
  $.fn.keepRatio = function(which) {
      var $this = $(this);
      var w = $this.width();
      var h = $this.height();
      var ratio = w/h;
      $(window).resize(function() {
          switch(which) {
              case 'width':
                  var nh = $this.width() / ratio;
                  $this.css('height', nh + 'px');
                  break;
              case 'height':
                  var nw = $this.height() * ratio;
                  $this.css('width', nw + 'px');
                  break;
          }
      });

  }
})( jQuery );      

$(document).ready(function(){
    $('#foo').keepRatio('width');
});

If you use JSON properly, you can have nested object without any issue :

var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
var theUrl = "/json-handler";
xmlhttp.open("POST", theUrl);
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xmlhttp.send(JSON.stringify({ "email": "[email protected]", "response": { "name": "Tester" } }));

Directly from the command line:

 for /L %n in (1,1,100) do @echo %n

Using a batch file:

 @echo off
 for /L %%n in (1,1,100) do echo %%n

Displays:

 1
 2
 3
 ...
 100

Put display:block on the css for the cell, and valign="top" that should do the trick

=$G1="X"

would be the correct (and easiest) method. Just select the entire sheet first, as conditional formatting only works on selected cells. I just tried it and it works perfectly. You must start at G1 rather than G2 otherwise it will offset the conditional formatting by a row.

An alternative is to use the maven shade plugin to build an uber-jar.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version> Your Version Here </version>
    <configuration>
            <!-- put your configurations here -->
    </configuration>
    <executions>
            <execution>
                    <phase>package</phase>
                    <goals>
                            <goal>shade</goal>
                    </goals>
            </execution>
    </executions>
</plugin>

//Extra currency symbol and currency formatting: "€3,311.50":
String result = (Decimal.Parse("000000331150") / 100).ToString("C");

//No currency symbol and no currency formatting: "3311.50"
String result = (Decimal.Parse("000000331150") / 100).ToString("f2");

in my case, i use below. I don't care what is its extention. :D i think it will help you

$exploded_filepath = explode(".", $filepath_or_URL);
$extension = end($exploded_filepath);
echo basename($filepath_or_URL, ".".$extension ); //will print out the the name without extension.

double signof(double a) { return (a == 0) ? 0 : (a<0 ? -1 : 1); }

I had a similar problem.

Issue was there was a trigger on the table that would write changes to an audit log table. Columns were missing in audit log table.

You can use column indices (letters) like this:

import pandas as pd
import numpy as np
file_loc = "path.xlsx"
df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")
print(df)

[Corresponding documentation][1]:

usecolsint, str, list-like, or callable default None

• If None, then parse all columns.
• If str, then indicates comma separated list of Excel column letters and column ranges (e.g. “A:E” or “A,C,E:F”). Ranges are inclusive of both sides.
• If list of int, then indicates list of column numbers to be parsed.

• If list of string, then indicates list of column names to be parsed.

  New in version 0.24.0.

• If callable, then evaluate each column name against it and parse the column if the callable returns True.

Returns a subset of the columns according to behavior above.

New in version 0.24.0.

What you are looking for is merging.

git merge master

With pull you fetch changes from a remote repository and merge them into the current branch.

You can imitate the C idiom in Python.

To read a buffer up to max_size number of bytes, you can do this:

with open(filename, 'rb') as f:
    while True:
        buf = f.read(max_size)
        if not buf:
            break
        process(buf)

Or, a text file line by line:

# warning -- not idiomatic Python! See below...
with open(filename, 'rb') as f:
    while True:
        line = f.readline()
        if not line:
            break
        process(line)

You need to use while True / break construct since there is no eof test in Python other than the lack of bytes returned from a read.

In C, you might have:

while ((ch != '\n') && (ch != EOF)) {
   // read the next ch and add to a buffer
   // ..
}

However, you cannot have this in Python:

 while (line = f.readline()):
     # syntax error

because assignments are not allowed in expressions in Python (although recent versions of Python can mimic this using assignment expressions, see below).

It is certainly more idiomatic in Python to do this:

# THIS IS IDIOMATIC Python. Do this:
with open('somefile') as f:
    for line in f:
        process(line)

Update: Since Python 3.8 you may also use assignment expressions:

 while line := f.readline():
     process(line)

The concept of number/length/dimensionality doesn't really make sense for an Object, and needing it suggests you really want an Array to me.

Edit: Pointed out to me that you want an O(1) for this. To the best of my knowledge no such way exists I'm afraid.

Thanks for above answers, with the help of those, after certain R&D for xamarin.android MVVMCross application, below worked

Flag specified for activity in method OnCreate

protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);
        this.Window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);
    }

For each MvxActivity, Theme is mentioned as below

 [Activity(
    LaunchMode = LaunchMode.SingleTop,
    ScreenOrientation = ScreenOrientation.Portrait,
    Theme = "@style/Theme.Splash",
    Name = "MyView"
    )]

My SplashStyle.xml looks like as below

<?xml version="1.0" encoding="utf-8"?>
<resources> 
    <style name="Theme.Splash" parent="Theme.AppCompat.Light.NoActionBar">
          <item name="android:statusBarColor">@color/app_red</item>
          <item name="android:colorPrimaryDark">@color/app_red</item>
    </style>
 </resources>

And I have V7 appcompact referred.

This works in Linux & Windows:

Python 3.x

>>> import sys
>>> print(sys.executable)
C:\path\to\python.exe

Python 2.x

>>> import sys
>>> print sys.executable
/usr/bin/python

This way:

db.collection_name.find().toArray().then(...function...)

My solution for Bootstrap 3:

.modal {
  overflow-y: hidden;
}
body.modal-open {
  margin-right: 0;
}

because for me the only overflow: hidden on the body.modal-open class did not prevent the page from shifting to the left due to the original margin-right: 15px.

If you're using Docker, reading the Docker image documentation (in the Setting WiredTiger cache size limits section) I found out that they set the default to consume all available memory regardless of memory limits you may have imposed on the container, so you would have to limit the RAM usage directly from the DB configuration.

1. Create you mongod.conf file:

# Limits cache storage
storage:
   wiredTiger:
      engineConfig:
         cacheSizeGB: 1 # Set the size you want

2. Now you can assign that config file to the container: docker run --name mongo-container -v /path/to/mongod.conf:/etc/mongo/mongod.conf -d mongo --config /etc/mongo/mongod.conf
3. Alternatively you could use a docker-compose.yml file:

version: '3'

services:
    mongo:
        image: mongo:4.2
        # Sets the config file
        command: --config /etc/mongo/mongod.conf
        volumes:
            - ./config/mongo/mongod.conf:/etc/mongo/mongod.conf
        # Others settings...

Indeed, it is O(n^2). See also a very similar example with the same runtime here.

A cleaner way to do this:

class Book {
    public Title: string;
    public Price: number;
    public Description: string;

    constructor(public BookId: number, public Author: string){}
}

Then

var bks: Book[] = [
    new Book(1, "vamsee")
];

You can use the built-in Dir function or the FileSystemObject.

• Dir Function: VBA: Dir Function

• FileSystemObject: VBA: FileSystemObject - Files Collection

They each have their own strengths and weaknesses.

Dir Function

The Dir Function is a built-in, lightweight method to get a list of files. The benefits for using it are:

• Easy to Use
• Good performance (it's fast)
• Wildcard support

The trick is to understand the difference between calling it with or without a parameter. Here is a very simple example to demonstrate:

Public Sub ListFilesDir(ByVal sPath As String, Optional ByVal sFilter As String)

    Dim sFile As String

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file name
    sFile = Dir(sPath & sFilter)

   'call it again until there are no more files
    Do Until sFile = ""

        Debug.Print sFile

        'subsequent calls without param return next file name
        sFile = Dir

    Loop

End Sub

If you alter any of the files inside the loop, you will get unpredictable results. It is better to read all the names into an array of strings before doing any operations on the files. Here is an example which builds on the previous one. This is a Function that returns a String Array:

Public Function GetFilesDir(ByVal sPath As String, _
    Optional ByVal sFilter As String) As String()

    'dynamic array for names
    Dim aFileNames() As String
    ReDim aFileNames(0)

    Dim sFile As String
    Dim nCounter As Long

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file
    sFile = Dir(sPath & sFilter)

    'call it until there is no filename returned
    Do While sFile <> ""

        'store the file name in the array
        aFileNames(nCounter) = sFile

        'subsequent calls without param return next file
        sFile = Dir

        'make sure your array is large enough for another
        nCounter = nCounter + 1
        If nCounter > UBound(aFileNames) Then
            'preserve the values and grow by reasonable amount for performance
            ReDim Preserve aFileNames(UBound(aFileNames) + 255)
        End If

    Loop

    'truncate the array to correct size
    If nCounter < UBound(aFileNames) Then
        ReDim Preserve aFileNames(0 To nCounter - 1)
    End If

    'return the array of file names
    GetFilesDir = aFileNames()

End Function

File System Object

The File System Object is a library for IO operations which supports an object-model for manipulating files. Pros for this approach:

• Intellisense
• Robust object-model

You can add a reference to to "Windows Script Host Object Model" (or "Windows Scripting Runtime") and declare your objects like so:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As FileSystemObject
    Dim oFolder As Folder
    Dim oFile As File

    Set oFSO = New FileSystemObject
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

If you don't want intellisense you can do like so without setting a reference:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As Object
    Dim oFolder As Object
    Dim oFile As Object

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

Wouldn't it be better to "wrap" the String in order to memorize the hashCode. In the normal String class hashCode() is O(N) the first time and then it is O(1) since it is kept for future use.

public class HashWrap {
    private final String value;
    private final int hash;

    public String get() {
        return value;
    }

    public HashWrap(String value) {
        this.value = value;
        String lc = value.toLowerCase();
        this.hash = lc.hashCode();
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o instanceof HashWrap) {
            HashWrap that = (HashWrap) o;
            return value.equalsIgnoreCase(that.value);
        } else {
            return false;
        }
    }

    @Override
    public int hashCode() {
        return this.hash;
    }

    //might want to implement compare too if you want to use with SortedMaps/Sets.
}

This would allow you to use any implementation of Hashtable in java and to have O(1) hasCode().

I recently wrote a gem to simplify this process and to neaten up your views, etc etc.

Check it out at: http://github.com/platform45/easy_dates

Notice: It did not format the document unless I corrected all mistakes. Check your file before pressing CTRLSHIFTF.

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

https://github.com/cscott/jsshaper implements a translator from JavaScript 1.8 to ECMAScript 5.1, which would allow you to use 'for each' in code running on webkit or node.

Try like this

SELECT (select max(Salary) from Employee) as MAXinmum),(max(salary) FROM Employee WHERE salary NOT IN (SELECT max(salary)) FROM Employee);

(Or)

Try this, n would be the nth item you would want to return

 SELECT DISTINCT(Salary) FROM table ORDER BY Salary DESC LIMIT n,1

In your case

 SELECT DISTINCT(column_name) FROM table_name ORDER BY column_name DESC limit 2,1;

Edit your package.json:

"build": "react-scripts build && mv build webapp"

TLDR

1. Pull & push again: git pull &&& git push.
2. Still a problem? Push into different branch: git push origin master:foo and merge it on remote repo.
3. Alternatively force the push by adding -f (denyCurrentBranch needs to be ignored).

Basically the error means that your repository is not up-to-date with the remote code (its index and work tree is inconsistent with what you pushed).

Normally you should pull first to get the recent changes and push it again.

If won't help, try pushing into different branch, e.g.:

git push origin master:foo

then merge this branch on the remote repository back with master.

If you changed some past commits intentionally via git rebase and you want to override repo with your changes, you probably want to force the push by adding -f/--force parameter (not recommended if you didn't do rebase). If still won't work, you need to set receive.denyCurrentBranch to ignore on remote as suggested by a git message via:

git config receive.denyCurrentBranch ignore

I have been running with the Ribo code posted above for over a year, and it has served us well. With recent updates (Gradle 3.x) though, I was no longer able to parse the AndroidManifest.xml, I was getting index out of bounds errors, and in general it was no longer able to parse the file.

Update: I now believe that our issues was with upgrading to Gradle 3.x. This article describes how AirWatch had issues and can be fixed by using a Gradle setting to use aapt instead of aapt2 AirWatch seems to be incompatible with Android Plugin for Gradle 3.0.0-beta1

In searching around I came across this open source project, and it's being maintained and I was able to get to the point and read both my old APKs that I could previously parse, and the new APKs that the logic from Ribo threw exceptions

https://github.com/xgouchet/AXML

From his example this is what I'm doing

  zf = new ZipFile(apkFile);

  //Getting the manifest
  ZipEntry entry = zf.getEntry("AndroidManifest.xml");
  InputStream is = zf.getInputStream(entry);

     // Read our manifest Document
     Document manifestDoc = new CompressedXmlParser().parseDOM(is);

     // Make sure we got a doc, and that it has children
     if (null != manifestDoc && manifestDoc.getChildNodes().getLength() > 0) {
        //
        Node firstNode = manifestDoc.getFirstChild();

        // Now get the attributes out of the node
        NamedNodeMap nodeMap = firstNode.getAttributes();

        // Finally to a point where we can read out our values
        versionName = nodeMap.getNamedItem("android:versionName").getNodeValue();
        versionCode = nodeMap.getNamedItem("android:versionCode").getNodeValue();
     }

I spotted this a little late, but I work with a similar problem (mortgage prepayment models). My solution has been to skip the pandas HDFStore layer and use straight pytables. I save each column as an individual HDF5 array in my final file.

My basic workflow is to first get a CSV file from the database. I gzip it, so it's not as huge. Then I convert that to a row-oriented HDF5 file, by iterating over it in python, converting each row to a real data type, and writing it to a HDF5 file. That takes some tens of minutes, but it doesn't use any memory, since it's only operating row-by-row. Then I "transpose" the row-oriented HDF5 file into a column-oriented HDF5 file.

The table transpose looks like:

def transpose_table(h_in, table_path, h_out, group_name="data", group_path="/"):
    # Get a reference to the input data.
    tb = h_in.getNode(table_path)
    # Create the output group to hold the columns.
    grp = h_out.createGroup(group_path, group_name, filters=tables.Filters(complevel=1))
    for col_name in tb.colnames:
        logger.debug("Processing %s", col_name)
        # Get the data.
        col_data = tb.col(col_name)
        # Create the output array.
        arr = h_out.createCArray(grp,
                                 col_name,
                                 tables.Atom.from_dtype(col_data.dtype),
                                 col_data.shape)
        # Store the data.
        arr[:] = col_data
    h_out.flush()

Reading it back in then looks like:

def read_hdf5(hdf5_path, group_path="/data", columns=None):
    """Read a transposed data set from a HDF5 file."""
    if isinstance(hdf5_path, tables.file.File):
        hf = hdf5_path
    else:
        hf = tables.openFile(hdf5_path)

    grp = hf.getNode(group_path)
    if columns is None:
        data = [(child.name, child[:]) for child in grp]
    else:
        data = [(child.name, child[:]) for child in grp if child.name in columns]

    # Convert any float32 columns to float64 for processing.
    for i in range(len(data)):
        name, vec = data[i]
        if vec.dtype == np.float32:
            data[i] = (name, vec.astype(np.float64))

    if not isinstance(hdf5_path, tables.file.File):
        hf.close()
    return pd.DataFrame.from_items(data)

Now, I generally run this on a machine with a ton of memory, so I may not be careful enough with my memory usage. For example, by default the load operation reads the whole data set.

This generally works for me, but it's a bit clunky, and I can't use the fancy pytables magic.

Edit: The real advantage of this approach, over the array-of-records pytables default, is that I can then load the data into R using h5r, which can't handle tables. Or, at least, I've been unable to get it to load heterogeneous tables.

Try:

next(g)

Check out this neat table that shows the differences in syntax between 2 and 3 when it comes to this.

I had a column that did not allow nulls and I was inserting a null value.

I create equations with random numbers in VBA and for x squared put in x^2.

I read each square (or textbox) text into a string.

I then read each character in the string in turn and note the location of the ^ ("hats")'s in each.

Say the hats were at positions 4, 8 and 12.

I then "chop out" the first hat - the position of the character to be superscripted is now 4, the position of the other hats is now 7 and 11. I chop out the second hat, the character to superscript is now at 7 and the hat has moved to 10. I chop out the last hat .. the superscript character is now position 10.

I now select each character in turn and change the font to superscript.

Thus I can fill a whole spreadsheet with algebra using ^ and then call a routine to tidy it up.

For big powers like x to the 23 I build x^2^3 and the above routine does it.

In order if someone would like to list all tables within specific database without using the "use" keyword:

SELECT TABLE_NAME FROM databasename.INFORMATION_SCHEMA.TABLES

Another minimalist Python solution without using numpy:

[0 if i < 0 else i for i in a]

No need to define any extra functions.

a = [1, 2, 3, -4, -5.23, 6]
[0 if i < 0 else i for i in a]

yields:

[1, 2, 3, 0, 0, 6]

You can check your respone content, just console.log it and you will see whitch property have a status code. If you do not understand jsons, please refer to the video: https://www.youtube.com/watch?v=Bv_5Zv5c-Ts

It explains very basic knowledge that let you feel more comfortable with javascript.

You can do it with shorter version of ajax request, please see code above:

$.get("example.url.com", function(data) {
                console.log(data);
            }).done(function() {
               // TO DO ON DONE
            }).fail(function(data, textStatus, xhr) {
                 //This shows status code eg. 403
                 console.log("error", data.status);
                 //This shows status message eg. Forbidden
                 console.log("STATUS: "+xhr);
            }).always(function() {
                 //TO-DO after fail/done request.
                 console.log("ended");
            });

Example console output:

error 403 
STATUS: Forbidden 
ended

The code says everything:

max@serv$ chmod 777 .

Okay, it doesn't say everything.

In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.

Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.

There is a way to catch the error directly in the except clause with ConnectionResetError, better to isolate the right error. This example also catches the timeout.

from urllib.request import urlopen 
from socket import timeout

url = "http://......"
try: 
    string = urlopen(url, timeout=5).read()
except ConnectionResetError:
    print("==> ConnectionResetError")
    pass
except timeout: 
    print("==> Timeout")
    pass

Please add this css code

input {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}

To add to Alex Kucherenko solution: the issue with the cursor getting disappearing after calling setInputType(0) is due to a framework bug on ICS (and JB).

The bug is documented here: https://code.google.com/p/android/issues/detail?id=27609.

To workaround this, call setRawInputType(InputType.TYPE_CLASS_TEXT) right after the setInputType call.

To stop the keyboard from appearing, just override OnTouchListener of the EditText and return true (swallowing the touch event):

ed.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                return true;
            }
        });

The reasons for the cursor appearing on GB devices and not on ICS+ had me tearing my hair out for a couple of hours, so I hope this saves someone's time.

Try with this. You will get the select box value in $_POST['Make'] and name will get in $_POST['selected_text']

<form method="POST" >
<label for="Manufacturer"> Manufacturer : </label>
  <select id="cmbMake" name="Make"     onchange="document.getElementById('selected_text').value=this.options[this.selectedIndex].text">
     <option value="0">Select Manufacturer</option>
     <option value="1">--Any--</option>
     <option value="2">Toyota</option>
     <option value="3">Nissan</option>
</select>
<input type="hidden" name="selected_text" id="selected_text" value="" />
<input type="submit" name="search" value="Search"/>
</form>


 <?php

if(isset($_POST['search']))
{

    $makerValue = $_POST['Make']; // make value

    $maker = mysql_real_escape_string($_POST['selected_text']); // get the selected text
    echo $maker;
}
 ?>

I tried for many ways to get my dialog be centered on the page and saw that the code:

$("#dialog").dialog("option", "position", 'top')

never change the dialog position when this was created.

Instead of, I change the selector level to get the entire dialog.

$("#dialog").parent() <-- This is the parent object that the dialog() function create on the DOM, this is because the selector $("#dialog") does not apply the attributes, top, left.

To center my dialog, I use the jQuery-Client-Centering-Plugin

$("#dialog").parent().centerInClient();

Here is a nice and simple way to do it (but on CENTOS), without braking the operating system.

yum install scl-utils

next

yum install centos-release-scl-rh

And lastly you install the version that you want, lets say python3.5

yum install rh-python35

And lastly:

scl enable rh-python35 bash

Since MAC-OS is a unix operating system, the way to do it it should be quite similar.

The dict.items iterates over the key-value pairs of a dictionary. Therefore for key, value in dictionary.items() will loop over each pair. This is documented information and you can check it out in the official web page, or even easier, open a python console and type help(dict.items). And now, just as an example:

>>> d = {'hello': 34, 'world': 2999}
>>> for key, value in d.items():
...   print key, value
...
world 2999
hello 34

The AttributeError is an exception thrown when an object does not have the attribute you tried to access. The class dict does not have any predictors attribute (now you know where to check it :) ), and therefore it complains when you try to access it. As easy as that.

Securely Download get-pip.py [1]

Run python get-pip.py. [2] This will install or upgrade pip. Additionally, it will install setuptools and wheel if they’re not installed already.

Ensure pip, setuptools, and wheel are up to date

While pip alone is sufficient to install from pre-built binary archives, up to date copies of the setuptools and wheel projects are useful to ensure you can also install from source archives:

python -m pip install --upgrade pip setuptools wheel

Well, in mathematics to convert a negative number to a positive number you just need to multiple the negative number by -1;

Then your solution could be like this:

a = a * -1;

or shorter:

a *= -1;

If you want to enable unblur, you cannot just add the blur CSS to the body, you need to blur each visible child one level directly under the body and then remove the CSS to unblur. The reason is because of the "Cascade" in CSS, you cannot undo the cascading of the CSS blur effect for a child of the body. Also, to blur the body's background image you need to use the pseudo element :before

I agree with the other answers that using two containers is preferable, but if you have your heart set on bunding multiple services in a single container you can use something like supervisord.

in Hipache for instance, the included Dockerfile runs supervisord, and the file supervisord.conf specifies for both hipache and redis-server to be run.

Example valid nginx.conf for reverse proxy; In case someone is stuck like me. where 10.x.x.x is the server where you are running the nginx proxy server and to which you are connecting to with the browser, and 10.y.y.y is where your real web server is running

events {
  worker_connections  4096;  ## Default: 1024
}
http {
 server {
   listen 80;
   listen [::]:80;

   server_name 10.x.x.x;
 
   location / {
       proxy_pass http://10.y.y.y:80/;
       proxy_set_header Host $host;
   }
 }
}

Here is the snippet if you want to do SSL pass through. That is if 10.y.y.y is running a HTTPS webserver. Here 10.x.x.x, or where the nignx runs is listening to port 443, and all traffic to 443 is directed to your target web server

events {
  worker_connections  4096;  ## Default: 1024
}

stream {
  server {
    listen     443;
    proxy_pass 10.y.y.y:443;
  }
}

and you can serve it up in docker too

 docker run --name nginx-container --rm --net=host   -v /home/core/nginx/nginx.conf:/etc/nginx/nginx.conf nginx

You need to switch your values:

/* No greater than 900px, no less than 400px */
@media (max-width:900px) and (min-width:400px) {
    .foo {
        display:none;
    }
}?

Demo: http://jsfiddle.net/xf6gA/ (using background color, so it's easier to confirm)

Using .data() will only add data to the jQuery object for that element. In order to add the information to the element itself you need to access that element using jQuery's .attr or native .setAttribute

$('div').attr('data-info', 1);
$('div')[0].setAttribute('data-info',1);

In order to access an element with the attribute set, you can simply select based on that attribute as you note in your post ($('div[data-info="1"]')), but when you use .data() you cannot. In order to select based on the .data() setting, you would need to use jQuery's filter function.

jsFiddle Demo

$('div').data('info', 1);_x000D_
//alert($('div').data('info'));//1_x000D_
_x000D_
$('div').filter(function(){_x000D_
   return $(this).data('info') == 1; _x000D_
}).text('222');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

You can start by reading the data structure alignment wikipedia article to get a better understanding of data alignment.

From the wikipedia article:

Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

From 6.54.8 Structure-Packing Pragmas of the GCC documentation:

For compatibility with Microsoft Windows compilers, GCC supports a set of #pragma directives which change the maximum alignment of members of structures (other than zero-width bitfields), unions, and classes subsequently defined. The n value below always is required to be a small power of two and specifies the new alignment in bytes.

1. #pragma pack(n) simply sets the new alignment.
2. #pragma pack() sets the alignment to the one that was in effect when compilation started (see also command line option -fpack-struct[=] see Code Gen Options).
3. #pragma pack(push[,n]) pushes the current alignment setting on an internal stack and then optionally sets the new alignment.
4. #pragma pack(pop) restores the alignment setting to the one saved at the top of the internal stack (and removes that stack entry). Note that #pragma pack([n]) does not influence this internal stack; thus it is possible to have #pragma pack(push) followed by multiple #pragma pack(n) instances and finalized by a single #pragma pack(pop).

Some targets, e.g. i386 and powerpc, support the ms_struct #pragma which lays out a structure as the documented __attribute__ ((ms_struct)).

1. #pragma ms_struct on turns on the layout for structures declared.
2. #pragma ms_struct off turns off the layout for structures declared.
3. #pragma ms_struct reset goes back to the default layout.

You are just updating the value of i in the loop. The value of i should also be added each time.

It is never a good idea to update the value of i inside the for loop. The for loop index should only be used as a counter. In your case, changing the value of i inside the loop will cause all sorts of confusion.

Create variable total that holds the sum of the numbers up to i.

So

 for (int i = 0; i < positiveInteger; i++)
        total += i;

You can use Popen in subprocess as they suggest.

with os, which is not recomment, it's like below:

import os
a  = os.popen('pwd').readlines()

Build.IS_DEBUGGABLE could be all right. It comes from "ro.debuggable"

With version 1.7 of the official 10gen driver, this is the current (non-obsolete) API:

const string uri = "mongodb://localhost/mydb";
var client = new MongoClient(uri);
var db = client.GetServer().GetDatabase(new MongoUrl(uri).DatabaseName);
var collection = db.GetCollection("mycollection");

Use char* strncpy(char* dest, char* src, int n) from <cstring>. In your case you will need to use the following code:

char* substr = malloc(4);
strncpy(substr, buff+10, 4);

Full documentation on the strncpy function here.

Use Controls object

For i = 1 To X
    Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next

I think the error because the elements are undefined ,so you need to add window.onload event which this event will defined your elements when the window is loaded.

window.addEventListener('load',Loaded,false);


    function Loaded(){
    var myButton = document.getElementById("myButton");
    var myTextfield = document.getElementById("myTextfield");

    function greetUser(userName) {
    var greeting = "Hello " + userName + "!";
    document.getElementsByTagName ("h2")[0].innerHTML = greeting;
    }

    myButton.onclick = function() {
    var userName = myTextfield.value;
    greetUser(userName);

    return false;
    }
    }

You can't use PHP to prevent a timeout issued by nginx.

To configure nginx to allow more time see the proxy_read_timeout directive.

At the latest Google Play Services 15.0.0, it occurs this error when you include entire play service like this

implementation 'com.google.android.gms:play-services:15.0.0'

Instead, you must specific the detail service like Google Drive

com.google.android.gms:play-services-drive:15.0.0

In jsp you can do it like this:

<%
boolean checkboxDisabled = true; //do your logic here
String checkboxState = checkboxDisabled ? "disabled" : "";
%>
<input type="checkbox" <%=checkboxState%>>

head(sort(x),..) or tail(sort(x),...) should work

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

"Install-Package Microsoft.AspNet.WebApi.Core" worked just fine.

We are also getting the same error while we are trying to access a same resource with in milliseconds. Like if i try to POST some data to www.abc.com/blog and with in milliseconds an other request will also go for the same resource i.e. www.abc.com/blog from the same user. So it'll give the 409 error.

TL;DR: Python does not need forward declarations. Simply put your function calls inside function def definitions, and you'll be fine.

def foo(count):
    print("foo "+str(count))
    if(count>0):
        bar(count-1)

def bar(count):
    print("bar "+str(count))
    if(count>0):
        foo(count-1)

foo(3)
print("Finished.")

recursive function definitions, perfectly successfully gives:

foo 3
bar 2
foo 1
bar 0
Finished.

However,

bug(13)

def bug(count):
    print("bug never runs "+str(count))

print("Does not print this.")

breaks at the top-level invocation of a function that hasn't been defined yet, and gives:

Traceback (most recent call last):
  File "./test1.py", line 1, in <module>
    bug(13)
NameError: name 'bug' is not defined

Python is an interpreted language, like Lisp. It has no type checking, only run-time function invocations, which succeed if the function name has been bound and fail if it's unbound.

Critically, a function def definition does not execute any of the funcalls inside its lines, it simply declares what the function body is going to consist of. Again, it doesn't even do type checking. So we can do this:

def uncalled():
    wild_eyed_undefined_function()
    print("I'm not invoked!")

print("Only run this one line.")

and it runs perfectly fine (!), with output

Only run this one line.

The key is the difference between definitions and invocations.

The interpreter executes everything that comes in at the top level, which means it tries to invoke it. If it's not inside a definition.
Your code is running into trouble because you attempted to invoke a function, at the top level in this case, before it was bound.

The solution is to put your non-top-level function invocations inside a function definition, then call that function sometime much later.

The business about "if __ main __" is an idiom based on this principle, but you have to understand why, instead of simply blindly following it.

There are certainly much more advanced topics concerning lambda functions and rebinding function names dynamically, but these are not what the OP was asking for. In addition, they can be solved using these same principles: (1) defs define a function, they do not invoke their lines; (2) you get in trouble when you invoke a function symbol that's unbound.

This is probably not the main reason why the create_all() method call doesn't work for people, but for me, the cobbled together instructions from various tutorials have it such that I was creating my db in a request context, meaning I have something like:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

def get_db():
  if 'db' not in g:
    g.db = SQLAlchemy(current_app)
  return g.db

I also have a separate cli command that also does the create_all:

# tasks/db.py
from lib.db import get_db

@current_app.cli.command('init-db')
def init_db():
  db = get_db()
  db.create_all()

I also am using a application factory.

When the cli command is run, a new app context is used, which means a new db is used. Furthermore, in this world, an import model in the init_db method does not do anything, because it may be that your model file was already loaded(and associated with a separate db).

The fix that I came around to was to make sure that the db was a single global reference:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

db = None
def get_db():
  global db
  if not db:
    db = SQLAlchemy(current_app)
  return db

I have not dug deep enough into flask, sqlalchemy, or flask-sqlalchemy to understand if this means that requests to the db from multiple threads are safe, but if you're reading this you're likely stuck in the baby stages of understanding these concepts too.

Just adding yet another bit of advice after trying a bunch of stuff myself and it not working....

I had GCC installed and the path to the includes set correctly. Had the std error as well, and couldn't get anything working for cout (and I suspect anything in the SL...)

Took me awhile to realize that g++ wasn't installed - gcc was but not g++. So just do:

sudo apt-get install g++

Restart eclipse. Assuming above mentioned details about gcc & paths to includes are fine, you should be okay now...

Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve(), dgesv spits this kind of error when the matrix you passed as a parameter is singular.

As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)

I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

if you have duration in h:mm, the actual value stored in that cell is the time converted to a real number, divided by 24 hours per day.

ex: 6:45 or 6 hours 45 minutes is 6.75 hours 6.75 hours / 24 = 0.28125 (in other words 6hrs45minutes is 28.125% of a day). If you use a column to convert your durations into actual numbers (in example, converting 6:45 into 0.28125) then you can do you multiplication or division and get the correct answer.

An alternative that has not been mentioned, but that may be a more efficient option for some (won't work with NULL entries) is to use a sparse index (entries in the index only exist when there is something in the field). Here is a sample data set:

db.foo.find()
{ "_id" : ObjectId("544540b31b5cf91c4893eb94"), "imageUrl" : "http://example.com/foo.jpg" }
{ "_id" : ObjectId("544540ba1b5cf91c4893eb95"), "imageUrl" : "http://example.com/bar.jpg" }
{ "_id" : ObjectId("544540c51b5cf91c4893eb96"), "imageUrl" : "http://example.com/foo.png" }
{ "_id" : ObjectId("544540c91b5cf91c4893eb97"), "imageUrl" : "http://example.com/bar.png" }
{ "_id" : ObjectId("544540ed1b5cf91c4893eb98"), "otherField" : 1 }
{ "_id" : ObjectId("544540f11b5cf91c4893eb99"), "otherField" : 2 }

Now, create the sparse index on imageUrl field:

db.foo.ensureIndex( { "imageUrl": 1 }, { sparse: true } )
{
    "createdCollectionAutomatically" : false,
    "numIndexesBefore" : 1,
    "numIndexesAfter" : 2,
    "ok" : 1
}

Now, there is always a chance (and in particular with a small data set like my sample) that rather than using an index, MongoDB will use a table scan, even for a potential covered index query. As it turns out that gives me an easy way to illustrate the difference here:

db.foo.find({}, {_id : 0, imageUrl : 1})
{ "imageUrl" : "http://example.com/foo.jpg" }
{ "imageUrl" : "http://example.com/bar.jpg" }
{ "imageUrl" : "http://example.com/foo.png" }
{ "imageUrl" : "http://example.com/bar.png" }
{  }
{  }

OK, so the extra documents with no imageUrl are being returned, just empty, not what we wanted. Just to confirm why, do an explain:

db.foo.find({}, {_id : 0, imageUrl : 1}).explain()
{
    "cursor" : "BasicCursor",
    "isMultiKey" : false,
    "n" : 6,
    "nscannedObjects" : 6,
    "nscanned" : 6,
    "nscannedObjectsAllPlans" : 6,
    "nscannedAllPlans" : 6,
    "scanAndOrder" : false,
    "indexOnly" : false,
    "nYields" : 0,
    "nChunkSkips" : 0,
    "millis" : 0,
    "server" : "localhost:31100",
    "filterSet" : false
}

So, yes, a BasicCursor equals a table scan, it did not use the index. Let's force the query to use our sparse index with a hint():

db.foo.find({}, {_id : 0, imageUrl : 1}).hint({imageUrl : 1})
{ "imageUrl" : "http://example.com/bar.jpg" }
{ "imageUrl" : "http://example.com/bar.png" }
{ "imageUrl" : "http://example.com/foo.jpg" }
{ "imageUrl" : "http://example.com/foo.png" }

And there is the result we were looking for - only documents with the field populated are returned. This also only uses the index (i.e. it is a covered index query), so only the index needs to be in memory to return the results.

This is a specialized use case and can't be used generally (see other answers for those options). In particular it should be noted that as things stand you cannot use count() in this way (for my example it will return 6 not 4), so please only use when appropriate.

If you want to apply the WHERE clause to the result of the UNION, then you have to embed the UNION in the FROM clause:

SELECT *
  FROM (SELECT * FROM TableA
        UNION
        SELECT * FROM TableB
       ) AS U
 WHERE U.Col1 = ...

I'm assuming TableA and TableB are union-compatible. You could also apply a WHERE clause to each of the individual SELECT statements in the UNION, of course.

Compress and Send Bitmap

The accepted answer will crash when the Bitmap is too large. I believe it's a 1MB limit. The Bitmap must be compressed into a different file format such as a JPG represented by a ByteArray, then it can be safely passed via an Intent.

Implementation

The function is contained in a separate thread using Kotlin Coroutines because the Bitmap compression is chained after the Bitmap is created from an url String. The Bitmap creation requires a separate thread in order to avoid Application Not Responding (ANR) errors.

Concepts Used

• Kotlin Coroutines notes.
• The Loading, Content, Error (LCE) pattern is used below. If interested you can learn more about it in this talk and video.
• LiveData is used to return the data. I've compiled my favorite LiveData resource in these notes.
• In Step 3, toBitmap() is a Kotlin extension function requiring that library to be added to the app dependencies.

Code

1. Compress Bitmap to JPG ByteArray after it has been created.

Repository.kt

suspend fun bitmapToByteArray(url: String) = withContext(Dispatchers.IO) {
    MutableLiveData<Lce<ContentResult.ContentBitmap>>().apply {
        postValue(Lce.Loading())
        postValue(Lce.Content(ContentResult.ContentBitmap(
            ByteArrayOutputStream().apply {
                try {                     
                    BitmapFactory.decodeStream(URL(url).openConnection().apply {
                        doInput = true
                        connect()
                    }.getInputStream())
                } catch (e: IOException) {
                   postValue(Lce.Error(ContentResult.ContentBitmap(ByteArray(0), "bitmapToByteArray error or null - ${e.localizedMessage}")))
                   null
                }?.compress(CompressFormat.JPEG, BITMAP_COMPRESSION_QUALITY, this)
           }.toByteArray(), "")))
        }
    }

ViewModel.kt

//Calls bitmapToByteArray from the Repository
private fun bitmapToByteArray(url: String) = liveData {
    emitSource(switchMap(repository.bitmapToByteArray(url)) { lce ->
        when (lce) {
            is Lce.Loading -> liveData {}
            is Lce.Content -> liveData {
                emit(Event(ContentResult.ContentBitmap(lce.packet.image, lce.packet.errorMessage)))
            }
            is Lce.Error -> liveData {
                Crashlytics.log(Log.WARN, LOG_TAG,
                        "bitmapToByteArray error or null - ${lce.packet.errorMessage}")
            }
        }
    })
}

2. Pass image as ByteArray via an Intent.

In this sample it's passed from a Fragment to a Service. It's the same concept if being shared between two Activities.

Fragment.kt

ContextCompat.startForegroundService(
    context!!,
    Intent(context, AudioService::class.java).apply {
        action = CONTENT_SELECTED_ACTION
        putExtra(CONTENT_SELECTED_BITMAP_KEY, contentPlayer.image)
    })

3. Convert ByteArray back to Bitmap.

Utils.kt

fun ByteArray.byteArrayToBitmap(context: Context) =
    run {
        BitmapFactory.decodeByteArray(this, BITMAP_OFFSET, size).run {
            if (this != null) this
            // In case the Bitmap loaded was empty or there is an error I have a default Bitmap to return.
            else AppCompatResources.getDrawable(context, ic_coinverse_48dp)?.toBitmap()
        }
    }

1. Find the process ID (PID) for the port (e.g.: 8080)

   On Windows:

   netstat -ao | find "8080"
   

   Other Platforms other than windows :

   lsof -i:8080
   

2. Kill the process ID you found (e.g.: 20712)

   On Windows:

   Taskkill /PID  20712 /F
   

   Other Platforms other than windows :

   kill -9 20712   or kill 20712
   

Using pure bash :

$ cat file.txt
US/Central - 10:26 PM (CST)
$ while read a b time x; do [[ $b == - ]] && echo $time; done < file.txt

another solution with bash regex :

$ [[ "US/Central - 10:26 PM (CST)" =~ -[[:space:]]*([0-9]{2}:[0-9]{2}) ]] &&
    echo ${BASH_REMATCH[1]}

another solution using grep and look-around advanced regex :

$ echo "US/Central - 10:26 PM (CST)" | grep -oP "\-\s+\K\d{2}:\d{2}"

another solution using sed :

$ echo "US/Central - 10:26 PM (CST)" |
    sed 's/.*\- *\([0-9]\{2\}:[0-9]\{2\}\).*/\1/'

another solution using perl :

$ echo "US/Central - 10:26 PM (CST)" |
    perl -lne 'print $& if /\-\s+\K\d{2}:\d{2}/'

and last one using awk :

$ echo "US/Central - 10:26 PM (CST)" |
    awk '{for (i=0; i<=NF; i++){if ($i == "-"){print $(i+1);exit}}}'

Here you go.

$('#timePicker').datetimepicker({
   // dateFormat: 'dd-mm-yy',
   format:'DD/MM/YYYY HH:mm:ss',
    minDate: getFormattedDate(new Date())
});

function getFormattedDate(date) {
    var day = date.getDate();
    var month = date.getMonth() + 1;
    var year = date.getFullYear().toString().slice(2);
    return day + '-' + month + '-' + year;
}

You need to pass datepicker() the date formatted correctly.

here's a better function

def strxor(a, b):     # xor two strings of different lengths
    if len(a) > len(b):
        return "".join([chr(ord(x) ^ ord(y)) for (x, y) in zip(a[:len(b)], b)])
    else:
        return "".join([chr(ord(x) ^ ord(y)) for (x, y) in zip(a, b[:len(a)])])

A few thing you could do:

1. Make sure that the "action" attribute on your form leads to the correct destination.
2. Try using $_REQUEST[] instead of $_POST, see if there is any change.

3. [Optional] Try including both a 'name' and an 'id' attribute e.g.

   <input type="text" name="firstname" id="firstname">
   

4. If you are in a Linux environment, check that you have both Read/Write permissions to the file.

In addition, this link might also help.

EDIT:

You could also substitute

<code>if(isset($_POST['submit'])){</code>

with this:

<code>if($_SERVER['REQUEST_METHOD'] == "POST"){ </code>

This is always the best way of checking whether or not a form has been submitted

Maybe just my all in one solution without important some new(regard the tempfile for creating temporary files :D )

import tempfile
abc = tempfile.NamedTemporaryFile(dir='/tmp/')
abc.name
abc.name.replace("/", " ").split()[-1] 

Getting the values of abc.name will be a string like this: '/tmp/tmpks5oksk7' So I can replace the / with a space .replace("/", " ") and then call split(). That will return a list and I get the last element of the list with [-1]

No need to get any module imported.

If you need an os independent method, works across Windows and Linux. Use python

$ python -c 'import multiprocessing as m; print m.cpu_count()'
16

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

It depends on the nature of your site.

I happen to work on a bit of software where IP tracking is important, and within a field consumed by parter sites I'd guess some 20% - 40% of requests are either detectably spoofed IPs or headers blanked out, depending on the time of day and where they came from. For a site which gets organic traffic (i.e. not through partners) I'd expect a much higher ratio of good IPs.

As Kosi said, be careful what you're doing with this - IPs are in no way a reliable way to identify unique visitors.

This one worked for me:

I set the height from HTML

canvas#scoreLineToAll.ct-chart.tab-pane.active[height="200"]
canvas#scoreLineTo3Months.ct-chart.tab-pane[height="200"]
canvas#scoreLineToYear.ct-chart.tab-pane[height="200"]

Then I disabled to maintaining aspect ratio

options: {
  responsive: true,
  maintainAspectRatio: false,

DECLARE @LastChangeDate as date 
SET @LastChangeDate = GETDATE() 

Building on Luiz's answer, but satisfying the "in case of draws the item with the lowest index should be returned" condition:

from statistics import mode, StatisticsError

def most_common(l):
    try:
        return mode(l)
    except StatisticsError as e:
        # will only return the first element if no unique mode found
        if 'no unique mode' in e.args[0]:
            return l[0]
        # this is for "StatisticsError: no mode for empty data"
        # after calling mode([])
        raise

Example:

>>> most_common(['a', 'b', 'b'])
'b'
>>> most_common([1, 2])
1
>>> most_common([])
StatisticsError: no mode for empty data

You need the path of the plugins directory of your local GATE install. So if Gate is installed in "/home/user/GATE_Developer_8.1", the code looks like this:

System.setProperty("gate.home", "/home/user/GATE_Developer_8.1/plugins");

You don't have to set gate.home from the command line. You can set it in your application, as long as you set it BEFORE you call Gate.init().

little php script to do it:

#!/usr/bin/env php
<?php
declare(strict_types = 1);
if ($argc !== 2) {
    fprintf ( STDERR, "usage: %s dir\n", $argv [0] );
    die ( 1 );
}
$dir = rtrim ( $argv [1], DIRECTORY_SEPARATOR );
if (! is_readable ( $dir )) {
    fprintf ( STDERR, "supplied path is not readable! (try running as an administrator?)" );
    die(1);
}
if (! is_dir ( $dir )) {
    fprintf ( STDERR, "supplied path is not a directory!" );
    die(1);
}
$files = glob ( $dir . DIRECTORY_SEPARATOR . '*.avi' );
foreach ( $files as $file ) {
    system ( "ffmpeg -i " . escapeshellarg ( $file ) . ' ' . escapeshellarg ( $file . '.mp4' ) );
}

In fact, xargs can run commands in parallel for you. There is a special -P max_procs command-line option for that. See man xargs.

I've had the same requirement, but the solutions here didn't quite get me across the line, due to the source of data for the recyclerView.

I was extracting the RecyclerViews' LinearLayoutManager state in onPause()

private Parcelable state;

Public void onPause() {
    state = mLinearLayoutManager.onSaveInstanceState();
}

Parcelable state is saved in onSaveInstanceState(Bundle outState), and extracted again in onCreate(Bundle savedInstanceState), when savedInstanceState != null.

However, the recyclerView adapter is populated and updated by a ViewModel LiveData object returned by a DAO call to a Room database.

mViewModel.getAllDataToDisplay(mSelectedData).observe(this, new Observer<List<String>>() {
    @Override
    public void onChanged(@Nullable final List<String> displayStrings) {
        mAdapter.swapData(displayStrings);
        mLinearLayoutManager.onRestoreInstanceState(state);
    }
});

I eventually found that restoring the instance state directly after the data is set in the adapter would keep the scroll-state across rotations.

I suspect this either is because the LinearLayoutManager state that I'd restored was being overwritten when the data was returned by the database call, or the restored state was meaningless against an 'empty' LinearLayoutManager.

If the adapter data is available directly (ie not contigent on a database call), then restoring the instance state on the LinearLayoutManager can be done after the adapter is set on the recyclerView.

The distinction between the two scenarios held me up for ages.

with open('test.txt', 'r') as inf, open('test1.txt', 'w') as outf:
    for line in inf:
        line = line.strip()
        if line:
            try:
                outf.write(str(int(line, 16)))
                outf.write('\n')
            except ValueError:
                print("Could not parse '{0}'".format(line))

As a simple one line expression recommend this,

^([a-zA-z0-9/\\''(),-\s]{2,255})$

I am using JDK 7 for maven project and I used -Dhttps.protocols=TLSv1.2 as argument in JRE. It has allowed to download all maven repository which were failing earlier.

Note: You can first preview what your patch will do:

First the stats:

git apply --stat a_file.patch

Then a dry run to detect errors:

git apply --check a_file.patch

Finally, you can use git am to apply your patch as a commit. This also allows you to sign off an applied patch.
This can be useful for later reference.

git am --signoff < a_file.patch 

See an example in this article:

In your git log, you’ll find that the commit messages contain a “Signed-off-by” tag. This tag will be read by Github and others to provide useful info about how the commit ended up in the code.

You can simply wrap your list as a data.frame (data.frame is in fact a special kind of list). Here is an example:

mylist = list() 
mylist[["a"]] = 1:10 
mylist[["b"]] = letters[1:10]
write.table(as.data.frame(mylist),file="mylist.csv", quote=F,sep=",",row.names=F)

or alternatively you can use write.csv (a wrapper around write.table). For the conversion of the list , you can use both as.data.frame(mylist) and data.frame(mylist).

To help in making a reproducible example, you can use functions like dput on your data.

Use a comma to specify a port number with SQL Server:

mycomputer.test.xxx.com,1234

It's not necessary to specify an instance name when specifying the port.

Lots more examples at http://www.connectionstrings.com/. It's saved me a few times.

n = int(input())          #n is the number of items you want to enter
d ={}                     
for i in range(n):        
    text = input().split()     #split the input text based on space & store in the list 'text'
    d[text[0]] = text[1]       #assign the 1st item to key and 2nd item to value of the dictionary
print(d)

INPUT:

3

A1023 CRT

A1029 Regulator

A1030 Therm

NOTE: I have added an extra line for each input for getting each input on individual lines on this site. As placing without an extra line creates a single line.

OUTPUT:

{'A1023': 'CRT', 'A1029': 'Regulator', 'A1030': 'Therm'}

Use this code:

QFile inputFile(fileName);
if (inputFile.open(QIODevice::ReadOnly))
{
   QTextStream in(&inputFile);
   while (!in.atEnd())
   {
      QString line = in.readLine();
      ...
   }
   inputFile.close();
}

This is how it would be done in a loop in C++(11):

   for (const auto& attack : m_attack)
    {  
        if (attack->m_num == input)
        {
            attack->makeDamage();
        }
    }

There is no for each in C++. Another option is to use std::for_each with a suitable functor (this could be anything that can be called with an Attack* as argument).

Recently, I really enjoy shorthand if else statements as a swtich case replacement. In my opinion, this is better in read and take less place. Just take a look:

var redirectUrl =
      status == LoginStatusEnum.Success ? "/SecretPage"
    : status == LoginStatusEnum.Failure ? "/LoginFailed"
    : status == LoginStatusEnum.Sms ? "/2-StepSms"
    : status == LoginStatusEnum.EmailNotConfirmed ? "/EmailNotConfirmed"
    : "/404-Error";

instead of

string redirectUrl;
switch (status)
{
    case LoginStatusEnum.Success:
        redirectUrl = "/SecretPage";
        break;
    case LoginStatusEnum.Failure:
        redirectUrl = "/LoginFailed";
        break;
    case LoginStatusEnum.Sms:
        redirectUrl = "/2-StepSms";
        break;
    case LoginStatusEnum.EmailNotConfirmed:
        redirectUrl = "/EmailNotConfirmed";
        break;
    default:
        redirectUrl = "/404-Error";
        break;
}

Android:autoText attribute also makes TextView auto focusable.

Call System.Reflection.MethodBase.GetCurrentMethod().Name from within the method.

<select name="flowers" size="5" style="height:200px">
 <option value="1">Rose</option>
 <option value="2">Tulip</option>
</select>

This simple solution allows to obtain visually a list of options, but to be able to select only one.

viewPager.addOnPageChangeListener(new OnPageChangeListener() {
            @Override
            public void onPageSelected(int position) {

                switch (position) {
    case 0:
        img_page1.setImageResource(R.drawable.dot_selected);
        img_page2.setImageResource(R.drawable.dot);
        img_page3.setImageResource(R.drawable.dot);
        img_page4.setImageResource(R.drawable.dot);
        break;

    case 1:
        img_page1.setImageResource(R.drawable.dot);
        img_page2.setImageResource(R.drawable.dot_selected);
        img_page3.setImageResource(R.drawable.dot);
        img_page4.setImageResource(R.drawable.dot);
        break;

    case 2:
        img_page1.setImageResource(R.drawable.dot);
        img_page2.setImageResource(R.drawable.dot);
        img_page3.setImageResource(R.drawable.dot_selected);
        img_page4.setImageResource(R.drawable.dot);
        break;

    case 3:
        img_page1.setImageResource(R.drawable.dot);
        img_page2.setImageResource(R.drawable.dot);
        img_page3.setImageResource(R.drawable.dot);
        img_page4.setImageResource(R.drawable.dot_selected);
        break;

    default:
        break;
    }


            }

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {

            }

            @Override
            public void onPageScrollStateChanged(int arg0) {

            }
        });

I had the same problem, but changing the contract namespace didn't work for me. So I tried a .Net 2 style web reference instead of a .Net 3.5 service reference. That worked.

To use a Web reference in Visual Studio 2008, click on 'Add Service Reference', then click 'Advanced' when the dialog box appears. In that you will find an option that will let you use a Web reference instead of a Service reference.

Registering DLL for Fundsite

Outdated or missing comdlg32.ocx runtime library can be the problem of causing this error. Make sure comdlg32.ocx file is not corrupted otherwise Download the File comdlg32.ocx (~60 Kb Zip).

Download the file and extract the comdlg32.ocx to your the Windows\System32 folder or Windows\SysWOW64. In my case i started with Windows\System32 but it didn’t work at my end, so I again saved in Windows\SysWOW64.

Type following command from Start, Run dialog:“c:\windows>System32\regsvr32 Comdlg32.ocx “ or “c:\windows>SysWOW64\regsvr32 Comdlg32.ocx ”

Now Comdlg.ocx File is register and next step is to register the DLL

1. Copy the Fundsite.Text.Encoding. dll into .Net Framework folder for 64bit on below path C:\Windows\Microsoft.NET\Framework64\v2.0.50727

2. Then on command prompt and go to directory C:\Windows\Microsoft.NET\Framework64\v2.0.50727 and then run the following command as shown below.

This will register the dll successfully.

C:\Windows\Microsoft.net\framework64\v2.0.50727>regasm "Dll Name".dll

Don't use iterators to do this. Maintain your own loop by incrementing a counter in the callback, and recursively calling the operation on the next item.

$.each(myMap, function(_, arr) {
    processArray(arr, 0);
});

function processArray(arr, i) {
    if (i >= arr.length) return;

    setTimeout(function () {
        $('#variant').fadeOut("slow", function () {
            $(this).text(i + "-" + arr[i]).fadeIn("slow");

            // Handle next iteration
            processArray(arr, ++i);
        });
    }, 6000);
}

Though there's a logic error in your code. You're setting the same container to more than one different value at (roughly) the same time. Perhaps you mean for each one to update its own container.

If you're using Spring 5.2.5 and Spring Boot 2.2.6 and want to override just a few properties instead of the whole file. You can use the new annotation: @DynamicPropertySource

@SpringBootTest
@Testcontainers
class ExampleIntegrationTests {

    @Container
    static Neo4jContainer<?> neo4j = new Neo4jContainer<>();

    @DynamicPropertySource
    static void neo4jProperties(DynamicPropertyRegistry registry) {
        registry.add("spring.data.neo4j.uri", neo4j::getBoltUrl);
    }
}

There are two additional ways to do it apart from the two methods mentioned in @PradeepJain's answer.

I would suggest not to use this approach and to fall back to this only as a last resort if you are not using [(ngModel)] directive and also not using data binding via [value]. Read this for more info.

Using ElementRef

app.component.html

<div>
      <input type="text" #searchInput placeholder="Search...">
      <button (click)="clearSearchInput()">Clear</button>
</div>

app.component.ts

export class App {
  @ViewChild('searchInput') searchInput: ElementRef;

  clearSearchInput(){
     this.searchInput.nativeElement.value = '';
  }
}

Using FormGroup

app.component.html

<form [formGroup]="form">
    <div *ngIf="first.invalid"> Name is too short. </div>
    <input formControlName="first" placeholder="First name">
    <input formControlName="last" placeholder="Last name">
    <button type="submit">Submit</button>
</form>
<button (click)="setValue()">Set preset value</button>
<button (click)="clearInputMethod1()">Clear Input Method 1</button>
<button (click)="clearInputMethod2()">Clear Input Method 2</button>

app.component.ts

export class AppComponent {
  form = new FormGroup({
    first: new FormControl('Nancy', Validators.minLength(2)),
    last: new FormControl('Drew'),
  });
  get first(): any { return this.form.get('first'); }
  get last(): any { return this.form.get('last'); }
  clearInputMethod1() { this.first.reset(); this.last.reset(); }
  clearInputMethod2() { this.form.setValue({first: '', last: ''}); }
  setValue() { this.form.setValue({first: 'Nancy', last: 'Drew'}); }
}

Try it out on stackblitz Clearing input in a FormGroup

Simply use below method

private fun hideKeyboard(activity: Activity, editText: EditText) {
    editText.clearFocus()
    (activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).hideSoftInputFromWindow(editText.windowToken, 0)
}

You could do it like this:

HTML

<table>
    <tr>
        <td>Cell 1</td>
        <td>Cell 2</td>
        <td>Cell 3</td>
        <td>Cell 4</td>
        <td><a href="#" id="show_1">Show Extra</a></td>
    </tr>
    <tr>
        <td colspan="5">
            <div id="extra_1" style="display: none;">
                <br>hidden row
                <br>hidden row
                <br>hidden row
            </div>
        </td>
    </tr>
</table>

jQuery

$("a[id^=show_]").click(function(event) {
    $("#extra_" + $(this).attr('id').substr(5)).slideToggle("slow");
    event.preventDefault();
});

See a demo on JSFiddle

If you need to stretch your background image while resizing the screen and you don't need compatibility with older browser versions this will do the work:

body {
    background-image: url('../images/image.jpg');
    background-repeat: no-repeat;
    background-size: cover;
}

The thread dump is written to the system out of the VM on which you executed the kill -3. If you are redirecting the console output of the JVM to a file, the thread dump will be in that file. If the JVM is running in an open console, then the thread dump will be displayed in its console.

With React Functional way

import React, { useEffect } from "react";
import ReactDOM from "react-dom";
import Button from "@material-ui/core/Button";

const App = () => {
  const saySomething = (something) => {
    console.log(something);
  };
  useEffect(() => {
    saySomething("from useEffect");
  });
  const handleClick = (e) => {
    saySomething("element clicked");
  };
  return (
    <Button variant="contained" color="primary" onClick={handleClick}>
      Hello World
    </Button>
  );
};

ReactDOM.render(<App />, document.querySelector("#app"));

You may also use box-shadow and add transparency to that dashed border via background-clip to let you see body background.

example

h1 {_x000D_
  text-align: center;_x000D_
  margin: auto;_x000D_
  box-shadow: 0 0 0 5px #1761A2;_x000D_
  border: dashed 3px #1761A2;_x000D_
  background: linear-gradient(#1761A2, #1761A2) no-repeat;_x000D_
  background-clip: border-box;_x000D_
  font-size: 2.5em;_x000D_
  text-shadow: 0 0 2px white, 0 0 2px white, 0 0 2px white, 0 0 2px white, 0 0 2px white;_x000D_
  font-size: 2.5em;_x000D_
  min-width: 12em;_x000D_
}_x000D_
body {_x000D_

Pen to play with

render in firefox:

We could use built-in function repr() or string interpolation fr'{}' escape all backwardslashs \ in Python 3.7.*

repr('my_string') or fr'{my_string}'

Check the Link: https://docs.python.org/3/library/functions.html#repr

Thanks for that info on the ControlToValidate LukeH!

What I was trying to do in my code was to only ensure that some text field A has some text in the field when text field B has a particular value. Otherwise, A can be blank or whatever else. Getting rid of the ControlToValidate="A" in my mark up fixed the issue for me.

Cheers!

They both track your changes to the collection, just call the SaveChanges() method that should update the DB.

You could also consider going parallel, especially if you don't care about the sequence and more about getting something done for each item:

SomeIEnumerable<T>.AsParallel().ForAll( Action<T> / Delegate / Lambda )

For example:

var numbers = new[] { 1, 2, 3, 4, 5 };
numbers.AsParallel().ForAll( Console.WriteLine );

HTH.

Open eclipse.ini in the installation directory, and observe the line with text:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 then it is 64 bit.

If it would be plugins/org.eclipse.equinox.launcher.win32.win32.x86_32_1.0.200.v20090519 then it is 32 bit.

Try this:

// Hide the login modal
$('#login').modal('hide');

// Show the next modal after the fade effect is finished
setTimeout(function(){ $('#lost').modal('show'); }, 500);

This simple hack works for me.

There are many great contributions here, but let me add mine non the less.

First thing i noticed is, you did not make any promises in the main file that you were going to create a function known as add(). This count have been done like this in the main file:

    int add(int a, int b); 

before your main function, that way your main function would recognize the add function and try to look for its executable code. So essentially your files should be

Main.c

    int add(int a, int b);

    int main(void) {
        int result = add(5,6);
        printf("%d\n", result);
    }  

and // add.c

    int add(int a, int b) {
        return a + b;
    }

This worked for me:

#include <iostream>
#include <pthread.h>
using namespace std;

void* print_message(void*) {

    cout << "Threading\n";
}

int main() {

    pthread_t t1;

    pthread_create(&t1, NULL, &print_message, NULL);
    cout << "Hello";

    // Optional.
    void* result;
    pthread_join(t1,&result);
    // :~

    return 0;
}

There are also these 'ways':

>>> dict.fromkeys(range(1, 4))
{1: None, 2: None, 3: None}
>>> dict(zip(range(1, 4), range(1, 4)))
{1: 1, 2: 2, 3: 3}

try this,

$(".head h3").html("New header");

or

$(".head h3").text("New header");

remember class selectors returns all the matching elements.

I have created following class

ConfigUtility.java

@Configuration
public class ConfigUtility {

    @Autowired
    private Environment env;

    public String getProperty(String pPropertyKey) {
        return env.getProperty(pPropertyKey);
    }
} 

and called as follow to get application.properties value

myclass.java

@Autowired
private ConfigUtility configUtil;

public AppResponse getDetails() {

  AppResponse response = new AppResponse();
    String email = configUtil.getProperty("emailid");
    return response;        
}

application.properties

unit tested, working as expected...

I also had similar problem where redirects were giving 404 or 405 randomly on my development server. It was an issue with gunicorn instances.

Turns out that I had not properly shut down the gunicorn instance before starting a new one for testing. Somehow both of the processes were running simultaneously, listening to the same port 8080 and interfering with each other. Strangely enough they continued running in background after I had killed all my terminals. Had to kill them manually using fuser -k 8080/tcp

you should run standlone.bat or .sh with -c standalone-full.xml switch may be work.

.row {
    letter-spacing: -.31em;
    word-spacing: -.43em;
}
.col-md-4 {
    float: none;
    display: inline-block;
    vertical-align: middle;
}

Note: .col-md-4 could be any grid column, its just an example here.

To reset your keyring.

1. Go into your home folder.

2. Press ctrl & h to show your hidden folders.

3. Now look in your .gnome2/keyrings directory.

4. Find the default.keyring file.

5. Move that file to a different folder.

6. Once done, reboot your computer.

You can easily create a Stream out of an Iterable or Iterator:

public static <T> Stream<T> stream(Iterable<T> iterable) {
    return StreamSupport.stream(
        Spliterators.spliteratorUnknownSize(
            iterable.iterator(),
            Spliterator.ORDERED
        ),
        false
    );
}

The API doc for IllegalArgumentException:

Thrown to indicate that a method has been passed an illegal or inappropriate argument.

From looking at how it is used in the JDK libraries, I would say:

• It seems like a defensive measure to complain about obviously bad input before the input can get into the works and cause something to fail halfway through with a nonsensical error message.

• It's used for cases where it would be too annoying to throw a checked exception (although it makes an appearance in the java.lang.reflect code, where concern about ridiculous levels of checked-exception-throwing is not otherwise apparent).

I would use IllegalArgumentException to do last ditch defensive argument checking for common utilities (trying to stay consistent with the JDK usage). Or where the expectation is that a bad argument is a programmer error, similar to an NullPointerException. I wouldn't use it to implement validation in business code. I certainly wouldn't use it for the email example.

You could declare your functions outside of the module.exports block.

var foo = function (req, res, next) {
  return ('foo');
}

var bar = function (req, res, next) {
  return foo();
}

Then:

module.exports = {
  foo: foo,
  bar: bar
}

A simple and proper way I've found to Handle Checked/Unchecked events using MVVM pattern is the Following, with Caliburn.Micro :

 <CheckBox IsChecked="{Binding IsCheckedBooleanProperty}" Content="{DynamicResource DisplayContent}" cal:Message.Attach="[Event Checked] = [Action CheckBoxClicked()]; [Event Unchecked] = [Action CheckBoxClicked()]" />

And implement a Method CheckBoxClicked() in the ViewModel, to do stuff you want.

Add a try/catch block, if the transaction succeeds it will commit the changes, if the transaction fails the transaction is rolled back:

BEGIN TRANSACTION [Tran1]

  BEGIN TRY

      INSERT INTO [Test].[dbo].[T1] ([Title], [AVG])
      VALUES ('Tidd130', 130), ('Tidd230', 230)

      UPDATE [Test].[dbo].[T1]
      SET [Title] = N'az2' ,[AVG] = 1
      WHERE [dbo].[T1].[Title] = N'az'

      COMMIT TRANSACTION [Tran1]

  END TRY

  BEGIN CATCH

      ROLLBACK TRANSACTION [Tran1]

  END CATCH  

Im not a java developer but was using a java app to test a RESTful API. In order for me to fix the error I had to install the intermediate certificates in the webserver in order to make the error go away. I was using lighttpd, the original certificate was installed on an IIS server. Hope it helps. These were the certificates I had missing on the server.

• CA.crt
• UTNAddTrustServer_CA.crt
• AddTrustExternalCARoot.crt

LocalLinks now seems to be obsolete.

LocalExplorer seems to have taken it's place and provides similar functionality:

https://chrome.google.com/webstore/detail/local-explorer-file-manag/eokekhgpaakbkfkmjjcbffibkencdfkl/reviews?hl=en

It's basically a chrome plugin that replaces file:// links with localexplorer:// links, combined with an installable protocol handler that intercepts localexplorer:// links.

Best thing I can find available right now, I have no affiliation with the developer.

To grant all priveleges on the database: mydb to the user: myuser, just execute:

GRANT ALL ON mydb.* TO 'myuser'@'localhost';

or:

GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'localhost';

The PRIVILEGES keyword is not necessary.

Also I do not know why the other answers suggest that the IDENTIFIED BY 'password' be put on the end of the command. I believe that it is not required.

In the specific case of react-router, using context is a valid case scenario, e.g.

class MyComponent extends React.Component {
  props: PropsType;

  static contextTypes = {
    router: PropTypes.object
  };

  render () {
    this.context.router;
  }
}

You can access an instance of the history via the router context, e.g. this.context.router.history.

I tested in linux centos

Map<String, String> env = System.getenv();   
for (String envName : env.keySet()) { 
 System.out.format("%s=%s%n", envName, env.get(envName)); 
}

System.out.println(env.get("USERNAME")); 

Here is how my code looks like. It also shows an example of how to use query parameters using a dictionary. It works on using Python 3.6:

import cx_Oracle

CONN_INFO = {
    'host': 'xxx.xx.xxx.x',
    'port': 12345,
    'user': 'SOME_SCHEMA',
    'psw': 'SECRETE',
    'service': 'service.server.com'
}

CONN_STR = '{user}/{psw}@{host}:{port}/{service}'.format(**CONN_INFO)

QUERY = '''
    SELECT
        *
    FROM
        USER
    WHERE
        NAME = :name
'''


class DB:
    def __init__(self):
        self.conn = cx_Oracle.connect(CONN_STR)

    def query(self, query, params=None):
        cursor = self.conn.cursor()
        result = cursor.execute(query, params).fetchall()
        cursor.close()
        return result


db = DB()
result = db.query(QUERY, {'name': 'happy'})

Can use getElementsByTagName

var x = document.getElementsByTagName("title")[0];

alert(x.innerHTML)

// or

alert(x.textContent)

// or

document.querySelector('title')

Edits as suggested by Paul

1. Entities are managed by javax.persistence.EntityManager instance using persistence context.
2. Each EntityManager instance is associated with a persistence context.
3. Within the persistence context, the entity instances and their lifecycle are managed.
4. Persistence context defines a scope under which particular entity instances are created, persisted, and removed.
5. A persistence context is like a cache which contains a set of persistent entities , So once the transaction is finished, all persistent objects are detached from the EntityManager's persistence context and are no longer managed.

if you want same string output then try below else use without double quotes for proper output

$str = '20130814';
  echo date('"F Y"', strtotime($str));

//output  : "August 2013"
