This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

For me nothing of previous works (maybe use application with yaml is an issue here), but get ride of that issue using that:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.Bean;
import org.springframework.util.unit.DataSize;

import javax.servlet.MultipartConfigElement;

@ServletComponentScan
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

    @Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        factory.setMaxFileSize(DataSize.ofBytes(512000000L));
        factory.setMaxRequestSize(DataSize.ofBytes(512000000L));
        return factory.createMultipartConfig();
    }
}

var price = 99.012334554;
price = price.toStringAsFixed(2);
print(price); // 99.01

That is the ref of dart. ref: https://api.dartlang.org/stable/2.3.0/dart-core/num/toStringAsFixed.html

Usually Header file syntax start with capital letter.I found that code written all in smaller letter

#ifndef DIAG_H
#define DIAG_H

#endif

If you have to log all args or your method have one argument, you can simply use getArgs like described in previous answers.

If you have to log a specific arg, you can annoted it and then recover its value like this :

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.PARAMETER)
public @interface Data {
 String methodName() default "";
}

@Aspect
public class YourAspect {

 @Around("...")
 public Object around(ProceedingJoinPoint point) throws Throwable {
  Method method = MethodSignature.class.cast(point.getSignature()).getMethod();
  Object[] args = point.getArgs();
  StringBuilder data = new StringBuilder();
    Annotation[][] parameterAnnotations = method.getParameterAnnotations();
    for (int argIndex = 0; argIndex < args.length; argIndex++) {
        for (Annotation paramAnnotation : parameterAnnotations[argIndex]) {
            if (!(paramAnnotation instanceof Data)) {
                continue;
            }
            Data dataAnnotation = (Data) paramAnnotation;
            if (dataAnnotation.methodName().length() > 0) {
                Object obj = args[argIndex];
                Method dataMethod = obj.getClass().getMethod(dataAnnotation.methodName());
                data.append(dataMethod.invoke(obj));
                continue;
            }
            data.append(args[argIndex]);
        }
    }
 }
}

Examples of use :

public void doSomething(String someValue, @Data String someData, String otherValue) {
    // Apsect will log value of someData param
}

public void doSomething(String someValue, @Data(methodName = "id") SomeObject someData, String otherValue) {
    // Apsect will log returned value of someData.id() method
}

Use gzip compression

Gzip compressing can greatly decrease the size of the response body and hence increase the speed of a web app. Use the compression middleware for gzip compression in your Express app. For example:

var compression = require('compression');
var express = require('express')
var app = express()
app.use(compression())

Just to expand on Matt DeKrey's answer, just deleting the csproj.user file (without needing to recreate solutions) was able to fix the problem for me.

The only side effect I had was I needed to reset the Start Action back to using a specific page.

Get all the checked checkbox value in an array - one liner

const data = [...document.querySelectorAll('.inp:checked')].map(e => e.value);_x000D_
console.log(data);

<div class="row">_x000D_
    <input class="custom-control-input inp"type="checkbox" id="inlineCheckbox1" Checked value="option1"> _x000D_
    <label class="custom-control-label" for="inlineCheckbox1">Option1</label>_x000D_
    <input class="custom-control-input inp"  type="checkbox" id="inlineCheckbox1" value="option2"> _x000D_
    <label class="custom-control-label" for="inlineCheckbox1">Option2</label>_x000D_
    <input class="custom-control-input inp" Checked  type="checkbox" id="inlineCheckbox1" value="option3"> _x000D_
    <label class="custom-control-label" for="inlineCheckbox1">Option3</label>_x000D_
</div>

The easiest way to match both

^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$

and

^[0-9]{3}-[0-9]{3}-[0-9]{4}$

is to use alternation ((...|...)): specify them as two mostly-separate options:

^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$

By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234, not (123)123-1234. So you might want to write:

^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$

(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)

I don't this the all the above answers are giving the exact solution for comparing two lists of Objects. Most of above approaches can be helpful in following limit of comparisons only - Size comparison - Reference comparison

But if we have same sized lists of objects and different data on the objects level then this comparison approaches won't help.

I think the following approach will work perfectly with overriding equals and hashcode method on the user-defined object.

I used Xstream lib for override equals and hashcode but we can override equals and hashcode by out won logics/comparison too.

Here is the example for your reference

    import com.thoughtworks.xstream.XStream;

    import java.text.ParseException;
    import java.util.ArrayList;
    import java.util.List;

    class TestClass {
      private String name;
      private String id;

      public void setName(String value) {
        this.name = value;
      }

      public String getName() {
        return this.name;
      }

      public String getId() {
        return id;
      }

      public void setId(String id) {
        this.id = id;
      }

      /**
       * @see java.lang.Object#equals(java.lang.Object)
       */
      @Override
      public boolean equals(Object o) {
        XStream xstream = new XStream();
        String oxml = xstream.toXML(o);
        String myxml = xstream.toXML(this);

        return myxml.equals(oxml);
      }

      /**
       * @see java.lang.Object#hashCode()
       */
      @Override
      public int hashCode() {
        XStream xstream = new XStream();
        String myxml = xstream.toXML(this);
        return myxml.hashCode();
      }
    }

    public class XstreamCompareTest {
      public static void main(String[] args) throws ParseException {
      checkObjectEquals();
}

      private static void checkObjectEquals() {
        List<TestClass> testList1 = new ArrayList<TestClass>();
        TestClass tObj1 = new TestClass();
        tObj1.setId("test3");
        tObj1.setName("testname3");
        testList1.add(tObj1);

        TestClass tObj2 = new TestClass();
        tObj2.setId("test2");
        tObj2.setName("testname2");
        testList1.add(tObj2);

        testList1.sort((TestClass t1, TestClass t2) -> t1.getId().compareTo(t2.getId()));

        List<TestClass> testList2 = new ArrayList<TestClass>();
        TestClass tObj3 = new TestClass();
        tObj3.setId("test3");
        tObj3.setName("testname3");
        testList2.add(tObj3);

        TestClass tObj4 = new TestClass();
        tObj4.setId("test2");
        tObj4.setName("testname2");
        testList2.add(tObj4);

        testList2.sort((TestClass t1, TestClass t2) -> t1.getId().compareTo(t2.getId()));

        if (isNotMatch(testList1, testList2)) {
          System.out.println("The list are not matched");
        } else {
          System.out.println("The list are matched");
        }

      }

      private static boolean isNotMatch(List<TestClass> clist1, List<TestClass> clist2) {
        return clist1.size() != clist2.size() || !clist1.equals(clist2);
      }
    }

The most important thing is that you can ignore the fields by Annotation (@XStreamOmitField) if you don't want to include any fields on the equal check of Objects. There are many Annotations like this to configure so have a look deep about the annotations of this lib.

I am sure this answer will save your time to identify the correct approach for comparing two lists of objects :). Please comment if you see any issues on this.

This error can occur if you are using a software update server which doesn't host the required package.

You can check this by running

defaults read /Library/Preferences/com.apple.SoftwareUpdate

and seeing if you have an entry called CatalogURL or AppleCatalogURL

You can point back at the Apple software update server by either removing this entry or using the command

sudo softwareupdate --clear-catalog

And then run the command line tools install again.

The issue is caused by this:

.catch((error) => {
  assert.isNotOk(error,'Promise error');
  done();
});

If the assertion fails, it will throw an error. This error will cause done() never to get called, because the code errored out before it. That's what causes the timeout.

The "Unhandled promise rejection" is also caused by the failed assertion, because if an error is thrown in a catch() handler, and there isn't a subsequent catch() handler, the error will get swallowed (as explained in this article). The UnhandledPromiseRejectionWarning warning is alerting you to this fact.

In general, if you want to test promise-based code in Mocha, you should rely on the fact that Mocha itself can handle promises already. You shouldn't use done(), but instead, return a promise from your test. Mocha will then catch any errors itself.

Like this:

it('should transition with the correct event', () => {
  ...
  return new Promise((resolve, reject) => {
    ...
  }).then((state) => {
    assert(state.action === 'DONE', 'should change state');
  })
  .catch((error) => {
    assert.isNotOk(error,'Promise error');
  });
});

I find it very convenient to build a regular expression pattern by stringing together multiple smaller patterns.

import re

string = "begin:id1:tag:middl:id2:tag:id3:end"
re_str1 = r'(?<=(\S{5})):'
re_str2 = r'(id\d+):(?=tag:)'
re_pattern = re.compile(re_str1 + re_str2)
match = re_pattern.findall(string)
print(match)

Output:

[('begin', 'id1'), ('middl', 'id2')]

ps aux | awk '{print $4"\t"$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr

or per process

ps aux | awk '{print $4"\t"$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr |grep mysql

This one worked for me:

<application
           android:allowBackup="true"
           android:icon="@mipmap/ic_launcher"
           android:label="@string/app_name"
           android:theme="@style/AppTheme" >
           <activity
               android:name=".MainActivity"
               android:label="@string/app_name"
               android:theme="@style/Theme.AppCompat.NoActionBar">

               <intent-filter>
                   <action android:name="android.intent.action.MAIN" />

                   <category android:name="android.intent.category.LAUNCHER" />
               </intent-filter>
           </activity>
</application>

$(document).ready(function() {
    $('select#select_2').change(function() {
        var selectedText = $(this).find('option:selected').text();
        alert(selectedText);
    });
});

One way is to get system properties that give you the path separator for the operating system, this tutorial explains how. You can then use a standard string join using the file.separator.

Using tidyverse:

x <- rnorm(100)
eps <- rnorm(100,0,.2)
df <- data.frame(x, eps) %>% 
  mutate(p1 = 3*x+eps, p2 = 2*x+eps) %>% 
  tidyr::gather("plot", "value", 3:4) %>% 
  ggplot(aes(x = x , y = value)) + 
    geom_point() + 
    geom_smooth() + 
    facet_wrap(~plot, ncol =2)

df

int and double have different semantics. Consider division. 1/2 is 0, 1.0/2.0 is 0.5. In any given situation, one of those answers will be right and the other wrong.

That said, there are programming languages, such as JavaScript, in which 64-bit float is the only numeric data type. You have to explicitly truncate some division results to get the same semantics as Java int. Languages such as Java that support integer types make truncation automatic for integer variables.

In addition to having different semantics from double, int arithmetic is generally faster, and the smaller size (32 bits vs. 64 bits) leads to more efficient use of caches and data transfer bandwidth.

"Day of Week" is actually something you can get directly from the php date() function with the format "l" or "N" respectively. Have a look at the manual

edit: Sorry I didn't read the posts of Kalium properly, he already explained that. My bad.

I was getting same error because of configuration issue in intellij. As shown in screenshot. Main and test module was pointing to two different JDK. (Press F12 on the intellij project to open module settings)

Also all my dto's were using @lombok.Builder which I changed it to @Data.

For me, it worked when I selected the correct bit of my Python version, NOT the one of my computer version.

Mine is 32bit, and my computer is 64bit. That was the problem and the 32bit version of fixed it.

to be exact, here is the one that worked for me: mysqlclient-1.3.13-cp37-cp37m-win32.whl

This may also happen if you have a faulty or accidental equation in your csv file. i.e - One of the cells in your csv file starts with an equals sign (=) (An excel equation) which will, in turn throw an error. If you fix, or remove this equation by getting rid of the equals sign, it should solve the ORA-06502 error.

If anyone stumbles across this and NEITHER Invalidate Cache or Update Kotlin's Version work:

1) First, make sure you can build it from outside the IDE. If you're using gradle, for instance:

gradle clean build

If everything goes well , then your environment is all good to work with Kotlin.

2) To fix the IDE build, try the following:

Project Structure -> {Select Module} -> Kotlin -> FIX

As suggested by a JetBrain's member here: https://discuss.kotlinlang.org/t/intellij-kotlin-project-screw-up/597

Yep, even in plain JavaScript it's pretty easy. You give an element an id and then you can use that as a "bookmark":

<div id="here">here</div>

If you want it to scroll there when a user clicks a link, you can just use the tried-and-true method:

<a href="#here">scroll to over there</a>

To do it programmatically, use scrollIntoView()

document.getElementById("here").scrollIntoView()

Between execution of left != null and queue.add(left) another thread could have changed the value of left to null.

To work around this you have several options. Here are some:

1. Use a local variable with smart cast:

    val node = left
    if (node != null) {
        queue.add(node)
    }
   

2. Use a safe call such as one of the following:

    left?.let { node -> queue.add(node) }
    left?.let { queue.add(it) }
    left?.let(queue::add)
   

3. Use the Elvis operator with return to return early from the enclosing function:

    queue.add(left ?: return)
   

   Note that break and continue can be used similarly for checks within loops.

The question is When do you use map vs flatMap in RxJava?. And I think a simple demo is more specific.

When you want to convert item emitted to another type , in your case converting file to String, map and flatMap can both work. But I prefer map operator because it's more clearly.

However in some place, flatMap can do magic work but map can't. For example, I want to get a user's info but I have to first get his id when user login in. Obviously I need two requests and they are in order.

Let's begin.

Observable<LoginResponse> login(String email, String password);

Observable<UserInfo> fetchUserInfo(String userId);

Here are two methods, one for login returned Response, and another for fetching user info.

login(email, password)
        .flatMap(response ->
                fetchUserInfo(response.id))
        .subscribe(userInfo -> {
            // get user info and you update ui now
        });

As you see, in function flatMap applies, at first I get user id from Response then fetch user info. When two requests are finished, we can do our job such as updating UI or save data into database.

However if you use map you can't write such nice code. In a word, flatMap can help us serialize requests.

For case when your interval's end it's date without hours like "from 2017-01-01 to whole day of 2017-01-16" it's better to adjust interval's to 23 hours 59 minutes and 59 seconds like:

end = end.Add(time.Duration(23*time.Hour) + time.Duration(59*time.Minute) + time.Duration(59*time.Second)) 

if now.After(start) && now.Before(end) {
    ...
}

you can find more information in spring context schema file. following is in spring-context-4.3.xsd

<conxtext:annotation-config />

Activates various annotations to be detected in bean classes: Spring's @Required and
@Autowired, as well as JSR 250's @PostConstruct, @PreDestroy and @Resource (if available),
JAX-WS's @WebServiceRef (if available), EJB 3's @EJB (if available), and JPA's
@PersistenceContext and @PersistenceUnit (if available). Alternatively, you may
choose to activate the individual BeanPostProcessors for those annotations.

Note: This tag does not activate processing of Spring's @Transactional or EJB 3's
@TransactionAttribute annotation. Consider the use of the <tx:annotation-driven>
tag for that purpose.

<context:component-scan>

Scans the classpath for annotated components that will be auto-registered as
Spring beans. By default, the Spring-provided @Component, @Repository, @Service, @Controller, @RestController, @ControllerAdvice, and @Configuration stereotypes    will be detected.

Note: This tag implies the effects of the 'annotation-config' tag, activating @Required,
@Autowired, @PostConstruct, @PreDestroy, @Resource, @PersistenceContext and @PersistenceUnit
annotations in the component classes, which is usually desired for autodetected components
(without external configuration). Turn off the 'annotation-config' attribute to deactivate
this default behavior, for example in order to use custom BeanPostProcessor definitions
for handling those annotations.

Note: You may use placeholders in package paths, but only resolved against system
properties (analogous to resource paths). A component scan results in new bean definitions
being registered; Spring's PropertySourcesPlaceholderConfigurer will apply to those bean
definitions just like to regular bean definitions, but it won't apply to the component
scan settings themselves.

Just had a similar problem trying to use SoapClient. Everything was working fine but in production, sometimes on page refresh, I would get the "SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from .." error.

I was using the params:

new \SoapClient($WSDL, array('cache_wsdl' => WSDL_CACHE_NONE, 'trace' => true, "exception" => 0)); 

Removing all the params worked for me:

new \SoapClient($WSDL); 

Timestamp in saving workbook path, the ":" needs to be changed. I used ":" -> "." which implies that I need to add the extension back "xlsx".

wb(x).SaveAs ThisWorkbook.Path & "\" & unique(x) & " - " & Format(Now(), "mm-dd-yy, hh.mm.ss") & ".xlsx"

Try this query:

SELECT cast(column_name as type) as col_identifier FROM tableName WHERE 1=1

Before comparing, the cast function will convert varchar type value to integer type.

Of the top of my head, can you try to use the 'q' operator for the string literal

something like

insert all
  into domo_queries values (q'[select 
substr(to_char(max_data),1,4) as year,
substr(to_char(max_data),5,6) as month,
max_data
from dss_fin_user.acq_dashboard_src_load_success
where source = 'CHQ PeopleSoft FS']')
select * from dual;

Note that the single quotes of your predicate are not escaped, and the string sits between q'[...]'.

There are at least three ways to get the "sum total of all the data in files and subdirectories" in bytes that work in both Linux/Unix and Git Bash for Windows, listed below in order from fastest to slowest on average. For your reference, they were executed at the root of a fairly deep file system (docroot in a Magento 2 Enterprise installation comprising 71,158 files in 30,027 directories).

1.

$ time find -type f -printf '%s\n' | awk '{ total += $1 }; END { print total" bytes" }'
748660546 bytes

real    0m0.221s
user    0m0.068s
sys     0m0.160s

2.

$ time echo `find -type f -print0 | xargs -0 stat --format=%s | awk '{total+=$1} END {print total}'` bytes
748660546 bytes

real    0m0.256s
user    0m0.164s
sys     0m0.196s

3.

$ time echo `find -type f -exec du -bc {} + | grep -P "\ttotal$" | cut -f1 | awk '{ total += $1 }; END { print total }'` bytes
748660546 bytes

real    0m0.553s
user    0m0.308s
sys     0m0.416s

These two also work, but they rely on commands that don't exist on Git Bash for Windows:

1.

$ time echo `find -type f -printf "%s + " | dc -e0 -f- -ep` bytes
748660546 bytes

real    0m0.233s
user    0m0.116s
sys     0m0.176s

2.

$ time echo `find -type f -printf '%s\n' | paste -sd+ | bc` bytes
748660546 bytes

real    0m0.242s
user    0m0.104s
sys     0m0.152s

If you only want the total for the current directory, then add -maxdepth 1 to find.

Note that some of the suggested solutions don't return accurate results, so I would stick with the solutions above instead.

$ du -sbh
832M    .

$ ls -lR | grep -v '^d' | awk '{total += $5} END {print "Total:", total}'
Total: 583772525

$ find . -type f | xargs stat --format=%s | awk '{s+=$1} END {print s}'
xargs: unmatched single quote; by default quotes are special to xargs unless you use the -0 option
4390471

$ ls -l| grep -v '^d'| awk '{total = total + $5} END {print "Total" , total}'
Total 968133

set nu set ai set tabstop=4 set ls=2 set autoindent

Add the above code in your .vimrc file. if .vimrc file is not present please create in your home directory (/home/name of user)

set nu -> This makes Vim display line numbers

set ai -> This makes Vim enable auto-indentation

set ls=2 -> This makes Vim show a status line

set tabstop=4 -> This makes Vim set tab of length 4 spaces (it is 8 by default)

The filename will also be displayed.

You can also do this:

newrow = [1,2,3]
A = numpy.concatenate((A,newrow))

You can use LOG such as :

Log.e(String, String) (error)
Log.w(String, String) (warning)
Log.i(String, String) (information)
Log.d(String, String) (debug)
Log.v(String, String) (verbose)

example code:

private static final String TAG = "MyActivity";
...
Log.i(TAG, "MyClass.getView() — get item number " + position);

As noted in the accepted answer - you can use the special { props.children } property. However - you can just pass a component as a prop as the title requests. I think this is cleaner sometimes as you might want to pass several components and have them render in different places. Here's the react docs with an example of how to do it:

https://reactjs.org/docs/composition-vs-inheritance.html

Make sure you are actually passing a component and not an object (this tripped me up initially).

The code is simply this:

const Parent = () => { 
  return (
    <Child  componentToPassDown={<SomeComp />}  />
  )
}

const Child = ({ componentToPassDown }) => { 
  return (
    <>
     {componentToPassDown}  
    </>
  )
}

In Python 3, you can monkey-patch the print function, to always send flush=True:

_orig_print = print

def print(*args, **kwargs):
    _orig_print(*args, flush=True, **kwargs)

As pointed out in a comment, you can simplify this by binding the flush parameter to a value, via functools.partial:

print = functools.partial(print, flush=True)

Crazy amount of complicated answers here. If you don't intend to process nodeJS files/database but just want to serve static html/css/js/images as your question suggest then simply install the pushstate-server module or similar;

Here's a "one liner" that will create and launch a mini site. Simply paste that entire block in your terminal in the appropriate directory.

mkdir mysite; \
cd mysite; \
npm install pushstate-server --save; \
mkdir app; \
touch app/index.html; \
echo '<h1>Hello World</h1>' > app/index.html; \
touch server.js; \
echo "var server = require('pushstate-server');server.start({ port: 3000, directory: './app' });" > server.js; \
node server.js

Open browser and go to http://localhost:3000. Done.

The server will use the app dir as the root to serve files from. To add additional assets just place them inside that directory.

To add to CrazyGeek's answer, get or get_or_create queries work only when there's one instance of the object in the database, filter is for two or more.

If a query can be for single or multiple instances, it's best to add an ID to the div and use an if statement e.g.

def updateUserCollection(request):
    data = json.loads(request.body)
    card_id = data['card_id']
    action = data['action']

    user = request.user
    card = Cards.objects.get(card_id=card_id)

    if data-action == 'add':
        collection = Collection.objects.get_or_create(user=user, card=card)
        collection.quantity + 1
        collection.save()

    elif data-action == 'remove':
        collection = Cards.objects.filter(user=user, card=card)
        collection.quantity = 0
        collection.update()

Note: .save() becomes .update() for updating multiple objects. Hope this helps someone, gave me a long day's headache.

CSS 'fixed' solution (like Facebook does):

body_temp = $("<div class='body_temp' />")
    .append($('body').contents())
    .css('position', 'fixed')
    .css('top', "-" + scrolltop + 'px')
    .width($(window).width())
    .appendTo('body');

to toggle to normal state:

var scrolltop = Math.abs($('.body_temp').position().top);
$('body').append($('.body_temp').contents()).scrollTop(scrolltop);

You should use PRIMARY from key_column_usage.constraint_name = "PRIMARY"

sample query,

SELECT k.column_name as PK, concat(tbl.TABLE_SCHEMA, '.`', tbl.TABLE_NAME, '`') as TABLE_NAME
FROM information_schema.TABLES tbl
JOIN information_schema.key_column_usage k on k.table_name = tbl.table_name
WHERE k.constraint_name='PRIMARY'
  AND tbl.table_schema='MYDB'
  AND tbl.table_type="BASE TABLE";

For me, a "+" was the key! This is my class(it is a nested one) :

namespace PortalServices
{
public class PortalManagement : WebService
{
    public class Merchant
    {}
}
}

and this line of code worked:

Type type = Type.GetType("PortalServices.PortalManagement+Merchant");

If you're looking for a portable C compiled tool:

http://stedolan.github.com/jq/

From the website:

jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you’d expect.

LDAP is the Lightweight Directory Access Protocol. Basically, it's a protocol used to access data from a database (or other source) and it's mostly suited for large numbers of queries and minimal updates (the sort of thing you would use for login information for example).

LDAP doesn't itself provide a database, just a means to query data in the database.

The main reason I used Reflector (and, I think, the main reason most people used it) was for its decompiler: it can translate a method's IL back into source code.

On that count, Monoflector would be the project to watch. It uses Cecil, which does the reflection, and Cecil.Decompiler, which does the decompilation. But Monoflector layers a UI on top of both libraries, which should give you a very good idea of how to use the API.

Monoflector is also a decent alternative to Reflector outright. It lets you browse the types and decompile the methods, which is 99% of what people used Reflector for. It's very rough around the edges, but I'm thinking that will change quickly.

It maybe solve your problem, check your files access level

$ sudo chmod -R 777 /"your files location"

Here is a more minimal method without any dependencies or libraries.
It requires the new fetch API. (Can I use it?)

var url = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="

fetch(url)
.then(res => res.blob())
.then(console.log)

With this method you can also easily get a ReadableStream, ArrayBuffer, text, and JSON.
(fyi this also works with node-fetch in Node)

As a function:

const b64toBlob = (base64, type = 'application/octet-stream') => 
  fetch(`data:${type};base64,${base64}`).then(res => res.blob())

I did a simple performance test towards Jeremy's ES6 sync version.
The sync version will block UI for a while. keeping the devtool open can slow the fetch performance

document.body.innerHTML += '<input autofocus placeholder="try writing">'
// get some dummy gradient image
var img=function(){var a=document.createElement("canvas"),b=a.getContext("2d"),c=b.createLinearGradient(0,0,1500,1500);a.width=a.height=3000;c.addColorStop(0,"red");c.addColorStop(1,"blue");b.fillStyle=c;b.fillRect(0,0,a.width,a.height);return a.toDataURL()}();


async function perf() {
  
  const blob = await fetch(img).then(res => res.blob())
  // turn it to a dataURI
  const url = img
  const b64Data = url.split(',')[1]

  // Jeremy Banks solution
  const b64toBlob = (b64Data, contentType = '', sliceSize=512) => {
    const byteCharacters = atob(b64Data);
    const byteArrays = [];
    
    for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
      const slice = byteCharacters.slice(offset, offset + sliceSize);
      
      const byteNumbers = new Array(slice.length);
      for (let i = 0; i < slice.length; i++) {
        byteNumbers[i] = slice.charCodeAt(i);
      }
      
      const byteArray = new Uint8Array(byteNumbers);
      
      byteArrays.push(byteArray);
    }
    
    const blob = new Blob(byteArrays, {type: contentType});
    return blob;
  }

  // bench blocking method
  let i = 500
  console.time('blocking b64')
  while (i--) {
    await b64toBlob(b64Data)
  }
  console.timeEnd('blocking b64')
  
  // bench non blocking
  i = 500

  // so that the function is not reconstructed each time
  const toBlob = res => res.blob()
  console.time('fetch')
  while (i--) {
    await fetch(url).then(toBlob)
  }
  console.timeEnd('fetch')
  console.log('done')
}

perf()

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

As answered here: How can I use a Windows batch file to measure the performance of console application?

Below batch "program" should do what you want. Please note that it outputs the data in centiseconds instead of milliseconds. The precision of the used commands is only centiseconds.

Here is an example output:

STARTTIME: 13:42:52,25
ENDTIME: 13:42:56,51
STARTTIME: 4937225 centiseconds
ENDTIME: 4937651 centiseconds
DURATION: 426 in centiseconds
00:00:04,26

Here is the batch script:

@echo off
setlocal

rem The format of %TIME% is HH:MM:SS,CS for example 23:59:59,99
set STARTTIME=%TIME%

rem here begins the command you want to measure
dir /s > nul
rem here ends the command you want to measure

set ENDTIME=%TIME%

rem output as time
echo STARTTIME: %STARTTIME%
echo ENDTIME: %ENDTIME%

rem convert STARTTIME and ENDTIME to centiseconds
set /A STARTTIME=(1%STARTTIME:~0,2%-100)*360000 + (1%STARTTIME:~3,2%-100)*6000 + (1%STARTTIME:~6,2%-100)*100 + (1%STARTTIME:~9,2%-100)
set /A ENDTIME=(1%ENDTIME:~0,2%-100)*360000 + (1%ENDTIME:~3,2%-100)*6000 + (1%ENDTIME:~6,2%-100)*100 + (1%ENDTIME:~9,2%-100)

rem calculating the duratyion is easy
set /A DURATION=%ENDTIME%-%STARTTIME%

rem we might have measured the time inbetween days
if %ENDTIME% LSS %STARTTIME% set set /A DURATION=%STARTTIME%-%ENDTIME%

rem now break the centiseconds down to hors, minutes, seconds and the remaining centiseconds
set /A DURATIONH=%DURATION% / 360000
set /A DURATIONM=(%DURATION% - %DURATIONH%*360000) / 6000
set /A DURATIONS=(%DURATION% - %DURATIONH%*360000 - %DURATIONM%*6000) / 100
set /A DURATIONHS=(%DURATION% - %DURATIONH%*360000 - %DURATIONM%*6000 - %DURATIONS%*100)

rem some formatting
if %DURATIONH% LSS 10 set DURATIONH=0%DURATIONH%
if %DURATIONM% LSS 10 set DURATIONM=0%DURATIONM%
if %DURATIONS% LSS 10 set DURATIONS=0%DURATIONS%
if %DURATIONHS% LSS 10 set DURATIONHS=0%DURATIONHS%

rem outputing
echo STARTTIME: %STARTTIME% centiseconds
echo ENDTIME: %ENDTIME% centiseconds
echo DURATION: %DURATION% in centiseconds
echo %DURATIONH%:%DURATIONM%:%DURATIONS%,%DURATIONHS%

endlocal
goto :EOF

Use of folloing command is depreciated

hadoop job -list
hadoop job -kill $jobId

consider using

mapred job -list
mapred job -kill $jobId

You have to wrap \n or \r in "", not ''. When using single quotes escape sequences will not be interpreted (except \' and \\).

The manual states:

If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:

• \n linefeed (LF or 0x0A (10) in ASCII)

• \r carriage return (CR or 0x0D (13) in ASCII)\

• (...)

I've had the same problem you describe. The web site I'm building can be accessed from a mobile phone and from the browser so I need an api to allow users to signup, login and do some specific tasks. Furthermore, I need to support scalability, the same code running on different processes/machines.

Because users can CREATE resources (aka POST/PUT actions) you need to secure your api. You can use oauth or you can build your own solution but keep in mind that all the solutions can be broken if the password it's really easy to discover. The basic idea is to authenticate users using the username, password and a token, aka the apitoken. This apitoken can be generated using node-uuid and the password can be hashed using pbkdf2

Then, you need to save the session somewhere. If you save it in memory in a plain object, if you kill the server and reboot it again the session will be destroyed. Also, this is not scalable. If you use haproxy to load balance between machines or if you simply use workers, this session state will be stored in a single process so if the same user is redirected to another process/machine it will need to authenticate again. Therefore you need to store the session in a common place. This is typically done using redis.

When the user is authenticated (username+password+apitoken) generate another token for the session, aka accesstoken. Again, with node-uuid. Send to the user the accesstoken and the userid. The userid (key) and the accesstoken (value) are stored in redis with and expire time, e.g. 1h.

Now, every time the user does any operation using the rest api it will need to send the userid and the accesstoken.

If you allow the users to signup using the rest api, you'll need to create an admin account with an admin apitoken and store them in the mobile app (encrypt username+password+apitoken) because new users won't have an apitoken when they sign up.

The web also uses this api but you don't need to use apitokens. You can use express with a redis store or use the same technique described above but bypassing the apitoken check and returning to the user the userid+accesstoken in a cookie.

If you have private areas compare the username with the allowed users when they authenticate. You can also apply roles to the users.

Summary:

An alternative without apitoken would be to use HTTPS and to send the username and password in the Authorization header and cache the username in redis.

send an output parameter like

@newId int output

at the end use

    select @newId = Scope_Identity() 

     return @newId 

It's quite old question, but my solution was to change versionCode (increase) in build.gradle

This is the best way which worked for me Execute this Command:-

$(dirname $(readlink $(which javac)))/java_home

Just a note ..

add:

android:name=".Globals"

or whatever you named your subclass to the existing <application> tag. I kept trying to add another <application> tag to the manifest and would get an exception.

Just discovered this:

SELECT * FROM OPENROWSET(BULK N'<PATH_TO_FILE>', SINGLE_CLOB) AS Contents

It'll pull in the contents of the file as varchar(max). Replace SINGLE_CLOB with:

SINGLE_NCLOB for nvarchar(max) SINGLE_BLOB for varbinary(max)

Thanks to http://www.mssqltips.com/sqlservertip/1643/using-openrowset-to-read-large-files-into-sql-server/ for this!

Unirest library simplifies this a lot. If you want to use it, you have to install unirest npm package. Then your code could look like this:

unirest.get("http://graph.facebook.com/517267866/?fields=picture")
  .send()
  .end(response=> {
    if (response.ok) {
      console.log("Got a response: ", response.body.picture)
    } else {
      console.log("Got an error: ", response.error)
    }
  })

So it seems your best option is going with the padding-bottom countered by negative margin-bottom strategy.

I made two examples. One with <header> inside .container, and another with it outside.

Both versions should work properly. Note the use of the following @media query so that it removes the extra padding on smaller screens...

@media screen and (max-width:991px) {
    .content { padding-top:0; }
}

Other than that, those examples should fix your problem.

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

HC-way :)

The file object is a buffer. When you read from the buffer, that portion that you read is consumed (the read position is shifted forward). When you read through the entire file, the read position is at the end of the file (EOF), so it returns nothing because there is nothing left to read.

If you have to reset the read position on a file object for some reason, you can do:

f.seek(0)

I had the same issue every time I tried to create a new project, but based on the console output, it was because of two versions of android-support-v4 that were different:

I don't know a lot about Eclipse. but I simply deleted the copy of the jar file from my project's libs folder so that it would use the appcompat_v7 jar file instead. This fixed my issue.

Eric Lippert recently had a very in-depth series of blog posts about this: "Every Binary Tree There Is" and "Every Tree There Is" (plus some more after that).

In answer to your specific question, he says:

The number of binary trees with n nodes is given by the Catalan numbers, which have many interesting properties. The nth Catalan number is determined by the formula (2n)! / (n+1)!n!, which grows exponentially.

Sometimes it may happen that there are multiple schema created in a database.

So to be specific schema we need to target, so this will help to do it.

SELECT count(*) into @colCnt FROM information_schema.columns WHERE table_name = 'mytable' AND column_name = 'mycolumn' and table_schema = DATABASE();
IF @colCnt = 0 THEN
    ALTER TABLE `mytable` ADD COLUMN `mycolumn` VARCHAR(20) DEFAULT NULL;
END IF;

First, what happens when T0 is not None? I would test that, then I would adjust the values I pass to plt.subplot(); maybe try values 131, 132, and 133, or values that depend whether or not T0 exists.

Second, after plt.show() is called, a new figure is created. To deal with this, you can

1. Call plt.savefig('tessstttyyy.png', dpi=100) before you call plt.show()

2. Save the figure before you show() by calling plt.gcf() for "get current figure", then you can call savefig() on this Figure object at any time.

For example:

fig1 = plt.gcf()
plt.show()
plt.draw()
fig1.savefig('tessstttyyy.png', dpi=100)

In your code, 'tesssttyyy.png' is blank because it is saving the new figure, to which nothing has been plotted.

For anyone looking for an answer in 2020. This worked for me.

In Views:

        model = AlarmInstance
        context_object_name = 'settings_context'

        template_name = 'insta_list.html'

        @register.filter
        def filter_unknown(self, aVal):
            result = aVal.filter(is_known=False)
            return result

        def filter_known(self, aVal):
            result = aVal.filter(is_known=True)

In pseudocode:

For each in model.child_object|view_filter:filter_arg

Hope that helps.

You can use ILIKE. i.e.

SELECT id FROM groups where name ILIKE 'administrator'

It is useful to think of MIME in the context of the client-server model. Clients and servers communicate over what is known as the HTTP protocol. In a http request or response, we can have a body. The Content-type or MIME type specifies what is the type of the body, like text/javascript or something else like audio, video, etc.

However, MIME types are not limited just to HTTP.

As the name suggests, MIME stands for Multipurpose Internet Mail Extensions. Originally, SMTP only supported ascii-encodings. However, there as a need for more. We could use MIME to slap a label on the content being transmitted or received.

This will give you duplicate rows:

vocabulary[duplicated(vocabulary$id),]

This will give you the number of duplicates:

dim(vocabulary[duplicated(vocabulary$id),])[1]

Example:

vocabulary2 <-rbind(vocabulary,vocabulary[1,]) #creates a duplicate at the end
vocabulary2[duplicated(vocabulary2$id),]
#            id year    sex education vocabulary
#21639 20040001 2004 Female         9          3
dim(vocabulary2[duplicated(vocabulary2$id),])[1]
#[1] 1 #=1 duplicate

EDIT

OK, with the additional information, here's what you should do: duplicated has a fromLast option which allows you to get duplicates from the end. If you combine this with the normal duplicated, you get all duplicates. The following example adds duplicates to the original vocabulary object (line 1 is duplicated twice and line 5 is duplicated once). I then use table to get the total number of duplicates per ID.

#Create vocabulary object with duplicates
voc.dups <-rbind(vocabulary,vocabulary[1,],vocabulary[1,],vocabulary[5,])

#List duplicates
dups <-voc.dups[duplicated(voc.dups$id)|duplicated(voc.dups$id, fromLast=TRUE),]
dups
#            id year    sex education vocabulary
#1     20040001 2004 Female         9          3
#5     20040008 2004   Male        14          1
#21639 20040001 2004 Female         9          3
#21640 20040001 2004 Female         9          3
#51000 20040008 2004   Male        14          1

#Count duplicates by id
table(dups$id)
#20040001 20040008 
#       3        2 

You need to use document.getElementById() in line 3.

If you try this right now in the console:

var img = document.createElement("img");_x000D_
img.src = "http://www.google.com/intl/en_com/images/logo_plain.png";_x000D_
var src = document.getElementById("header");_x000D_
src.appendChild(img);

<div id="header"></div>

... you'd get this:

You can also do this in phpMyAdmin without writing SQL.

• Click on a database name in the left column.
• Click on a table name in the left column.
• Click the "Operations" tab at the top.
• Under "Table options" there should be a field for AUTO_INCREMENT (only on tables that have an auto-increment field).
• Input desired value and click the "Go" button below.

Note: You'll see that phpMyAdmin is issuing the same SQL that is mentioned in the other answers.

Queue is an interface. You can't instantiate an interface directly except via an anonymous inner class. Typically this isn't what you want to do for a collection. Instead, choose an existing implementation. For example:

Queue<Integer> q = new LinkedList<Integer>();

or

Queue<Integer> q = new ArrayDeque<Integer>();

Typically you pick a collection implementation by the performance and concurrency characteristics you're interested in.

Yes its called negative lookahead. It goes like this - (?!regex here). So abc(?!def) will match abc not followed by def. So it'll match abce, abc, abck, etc.

Similarly there is positive lookahead - (?=regex here). So abc(?=def) will match abc followed by def.

There are also negative and positive lookbehind - (?<!regex here) and (?<=regex here) respectively

One point to note is that the negative lookahead is zero-width. That is, it does not count as having taken any space.

So it may look like a(?=b)c will match "abc" but it won't. It will match 'a', then the positive lookahead with 'b' but it won't move forward into the string. Then it will try to match the 'c' with 'b' which won't work. Similarly ^a(?=b)b$ will match 'ab' and not 'abb' because the lookarounds are zero-width (in most regex implementations).

As others have noted, writelines is a misnomer (it ridiculously does not add newlines to the end of each line).

To do that, explicitly add it to each line:

with open(dst_filename, 'w') as f:
    f.writelines(s + '\n' for s in lines)

It's better practise, safer and more polite to detect if the process is running and tell the user to close it manually. Of course you could also add a timeout and kill the process if they've gone away...

SELECT
    t.A,
    t.B,
    t.C,
    ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS number
FROM tableZ AS t

See working example at SQLFiddle

Of course, you may want to define the row-numbering order – if so, just swap OVER (ORDER BY (SELECT 1)) for, e.g., OVER (ORDER BY t.C), like in a normal ORDER BY clause.

Use onkeypress . Check if the pressed key is enter (keyCode = 13). if yes, call the searching() function.

HTML

<input name="keywords" type="text" id="keywords" size="50"  onkeypress="handleKeyPress(event)">

JAVASCRIPT

function handleKeyPress(e){
 var key=e.keyCode || e.which;
  if (key==13){
     searching();
  }
}

Here is a snippet showing it in action:

document.getElementById("msg1").innerHTML = "Default";_x000D_
function handle(e){_x000D_
 document.getElementById("msg1").innerHTML = "Trigger";_x000D_
 var key=e.keyCode || e.which;_x000D_
  if (key==13){_x000D_
     document.getElementById("msg1").innerHTML = "HELLO!";_x000D_
  }_x000D_
}

<input type="text" name="box22" value="please" onkeypress="handle(event)"/>_x000D_
<div id="msg1"></div>

The reject actually takes one parameter: that's the exception that occurred in your code that caused the promise to be rejected. So, when you call reject() the exception value is undefined, hence the "undefined" part in the error that you get.

You do not show the code that uses the promise, but I reckon it is something like this:

var promise = doSth();
promise.then(function() { doSthHere(); });

Try adding an empty failure call, like this:

promise.then(function() { doSthHere(); }, function() {});

This will prevent the error to appear.

However, I would consider calling reject only in case of an actual error, and also... having empty exception handlers isn't the best programming practice.

You can have a look here. I have the detailed process described with images, right from creating the certificate, to app key to provisioning profile, to eventually the pem. http://docs.moengage.com/docs/apns-certificate-pem-file

I did the redistributable repair thing, but for me it worked after I installed Office365.

(for me it also was the last failing package on the list).

The recommended way to do this from the current v4 docs is:

$font-size-base: 0.8rem;
$line-height-base: 1;

Be sure to define the variables above the bootstrap css include and they will override the bootstrap.

No need for anything else and this is the cleanest way

It's described quite clearly in the docs https://getbootstrap.com/docs/4.1/content/typography/#global-settings

So, after update I had the same issue. I was using PEM key_file without extension and simply adding .pem fixed my issue. Now the file is key_file.pem.

To see all keys of Jsonobject use this

    String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";
    JSONObject obj = new JSONObject(JSON);
    Iterator iterator = obj.keys();
    String key = null;
    while (iterator.hasNext()) {
        key = (String) iterator.next();
        System.out.pritnln(key);
    }

Here is an answer coming right from the libc6! Taking a look at /usr/include/x86_64-linux-gnu/bits/byteswap.h, I found the trick you were looking for.

A few critics of previous solutions:

• Kip's solution does not permit evaluating to an expression, which is in the end often needed.
• coppro's solution does not permit assigning a variable as the expressions are separate, but can evaluate to an expression.
• Steve Jessop's solution uses the C++11 auto keyword, that's fine, but feel free to use the known/expected type instead.

The trick is to use both the (expr,expr) construct and a {} scope:

#define MACRO(X,Y) \
  ( \
    { \
      register int __x = static_cast<int>(X), __y = static_cast<int>(Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  )

Note the use of the register keyword, it's only a hint to the compiler. The X and Y macro parameters are (already) surrounded in parenthesis and casted to an expected type. This solution works properly with pre- and post-increment as parameters are evaluated only once.

For the example purpose, even though not requested, I added the __x + __y; statement, which is the way to make the whole bloc to be evaluated as that precise expression.

It's safer to use void(); if you want to make sure the macro won't evaluate to an expression, thus being illegal where an rvalue is expected.

However, the solution is not ISO C++ compliant as will complain g++ -pedantic:

warning: ISO C++ forbids braced-groups within expressions [-pedantic]

In order to give some rest to g++, use (__extension__ OLD_WHOLE_MACRO_CONTENT_HERE) so that the new definition reads:

#define MACRO(X,Y) \
  (__extension__ ( \
    { \
      register int __x = static_cast<int>(X), __y = static_cast<int>(Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  ))

In order to improve my solution even a bit more, let's use the __typeof__ keyword, as seen in MIN and MAX in C:

#define MACRO(X,Y) \
  (__extension__ ( \
    { \
      __typeof__(X) __x = (X); \
      __typeof__(Y) __y = (Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  ))

Now the compiler will determine the appropriate type. This too is a gcc extension.

Note the removal of the register keyword, as it would the following warning when used with a class type:

warning: address requested for ‘__x’, which is declared ‘register’ [-Wextra]

Yes you can negate the test as SiegeX has already pointed out.

However you shouldn't use regular expressions for this - it can fail if your path contains special characters. Try this instead:

[[ ":$PATH:" != *":$1:"* ]]

MySQL version: 5.5.28-0ubuntu0.12.04.2-log

I was also under the impression that JOIN is always better than a sub-query in MySQL, but EXPLAIN is a better way to make a judgment. Here is an example where sub queries work better than JOINs.

Here is my query with 3 sub-queries:

EXPLAIN SELECT vrl.list_id,vrl.ontology_id,vrl.position,l.name AS list_name, vrlih.position AS previous_position, vrl.moved_date 
FROM `vote-ranked-listory` vrl 
INNER JOIN lists l ON l.list_id = vrl.list_id 
INNER JOIN `vote-ranked-list-item-history` vrlih ON vrl.list_id = vrlih.list_id AND vrl.ontology_id=vrlih.ontology_id AND vrlih.type='PREVIOUS_POSITION' 
INNER JOIN list_burial_state lbs ON lbs.list_id = vrl.list_id AND lbs.burial_score < 0.5 
WHERE vrl.position <= 15 AND l.status='ACTIVE' AND l.is_public=1 AND vrl.ontology_id < 1000000000 
 AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=43) IS NULL 
 AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=55) IS NULL 
 AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=246403) IS NOT NULL 
ORDER BY vrl.moved_date DESC LIMIT 200;

EXPLAIN shows:

A comparison of the rows column tells the difference and the query with JOINs is using Using temporary; Using filesort.

Of course when I run both the queries, the first one is done in 0.02 secs, the second one does not complete even after 1 min, so EXPLAIN explained these queries properly.

If I do not have the INNER JOIN on the list_tag table i.e. if I remove

AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=246403) IS NOT NULL  

from the first query and correspondingly:

INNER JOIN list_tag lt3 ON lt3.list_id = vrl.list_id AND lt3.tag_id = 246403

from the second query, then EXPLAIN returns the same number of rows for both queries and both these queries run equally fast.

Not answering OPs question directly, but for the people finding this question in search of clarity on what's the difference between allow,deny and deny,allow:

Read the comma as a "but".

• allow but deny: whitelist with exceptions.
  everything is denied, except items on the allow list, except items on the deny list
• deny but allow: blacklist with exceptions.
  everything is allowed, except items on the deny list, except items on the allow list

allow only one country access, but exclude proxies within this country

OP needed a whitelist with exceptions, therefore allow,deny instead of deny,allow

How about i-net Clear Reports (used to be i-net Crystal-Clear).

Though not free, you should also consider this low-cost, non-free, non-open-source reporting solution that can fully compete with Crystal Reports - and is Java-based.

I think it's even more cost efficient than "free ones". A small company may have to think closely about free things, but will then have to invest into manpower to find out how everything works and so on. Large companies will for sure subscribe to premium support services that cost a lot. See this article for reference

i-net Clear Reports has a very low price tag with great support for free and even better premium support via yearly subscriptions.

Disclosure: Yeah, I work for the company who built this, so I'm biased. But I honestly believe in what I just wrote.

If the question is how to convert an integer itself (not its string equivalent) into bytes, I think the robust answer is:

>>> i = 5
>>> i.to_bytes(2, 'big')
b'\x00\x05'
>>> int.from_bytes(i.to_bytes(2, 'big'), byteorder='big')
5

More information on these methods here:

2. https://docs.python.org/3.8/library/stdtypes.html#int.from_bytes

Put the h1 and h2 in a container with an id of container then:

From the Android Developers documentation about Signing your app :

Expiry of the debug certificate

[...] The file is stored in the following locations:

• ~/.android/ on OS X and Linux
• C:\Documents and Settings\<user>\.android\ on Windows XP
• C:\Users\<user>\.android\ on Windows Vista and Windows 7, 8, and 10

this would be perfect cause we are doing operation on matrix, and the answer should be a single number

sum(sum(matrix==value))

Created a base class based on @sky-dev implementation. So this can be easily applied to multiple contexts, and entities.

public abstract class BaseDbContext<TEntity> : DbContext where TEntity : class
{
    public BaseDbContext(string connectionString)
        : base(connectionString)
    {
    }
    public override int SaveChanges()
    {

        UpdateDates();
        return base.SaveChanges();
    }

    private void UpdateDates()
    {
        foreach (var change in ChangeTracker.Entries<TEntity>())
        {
            var values = change.CurrentValues;
            foreach (var name in values.PropertyNames)
            {
                var value = values[name];
                if (value is DateTime)
                {
                    var date = (DateTime)value;
                    if (date < SqlDateTime.MinValue.Value)
                    {
                        values[name] = SqlDateTime.MinValue.Value;
                    }
                    else if (date > SqlDateTime.MaxValue.Value)
                    {
                        values[name] = SqlDateTime.MaxValue.Value;
                    }
                }
            }
        }
    }
}

Usage:

public class MyContext: BaseDbContext<MyEntities>
{

    /// <summary>
    /// Initializes a new instance of the <see cref="MyContext"/> class.
    /// </summary>
    public MyContext()
        : base("name=MyConnectionString")
    {
    }
    /// <summary>
    /// Initializes a new instance of the <see cref="MyContext"/> class.
    /// </summary>
    /// <param name="connectionString">The connection string.</param>
    public MyContext(string connectionString)
        : base(connectionString)
    {
    }

     //DBcontext class body here (methods, overrides, etc.)
 }

For environments where here documents are unavailable (Makefile, Dockerfile, etc) you can often use printf for a reasonably legible and efficient solution.

printf '%s\n' '#!/bin/sh' '# Second line' \
    '# Third line' \
    '# Conveniently mix single and double quotes, too' \
    "# Generated $(date)" \
    '# ^ the date command executes when the file is generated' \
    'for file in *; do' \
    '    echo "Found $file"' \
    'done' >outputfile

I am using Angular 4 with the 4.3 httpClient object. I modified an answer I found in Js' Technical Blog which creates a link object, uses it to do the download, then destroys it.

Client:

doDownload(id: number, contentType: string) {
    return this.http
        .get(this.downloadUrl + id.toString(), { headers: new HttpHeaders().append('Content-Type', contentType), responseType: 'blob', observe: 'body' })
}

downloadFile(id: number, contentType: string, filename:string)  {

    return this.doDownload(id, contentType).subscribe(  
        res => { 
            var url = window.URL.createObjectURL(res);
            var a = document.createElement('a');
            document.body.appendChild(a);
            a.setAttribute('style', 'display: none');
            a.href = url;
            a.download = filename;
            a.click();
            window.URL.revokeObjectURL(url);
            a.remove(); // remove the element
        }, error => {
            console.log('download error:', JSON.stringify(error));
        }, () => {
            console.log('Completed file download.')
        }); 

} 

The value of this.downloadUrl has been set previously to point to the api. I am using this to download attachments, so I know the id, contentType and filename: I am using an MVC api to return the file:

 [ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]
    public FileContentResult GetAttachment(Int32 attachmentID)
    { 
        Attachment AT = filerep.GetAttachment(attachmentID);            
        if (AT != null)
        {
            return new FileContentResult(AT.FileBytes, AT.ContentType);  
        }
        else
        { 
            return null;
        } 
    } 

The attachment class looks like this:

 public class Attachment

The filerep repository returns the file from the database.

Hope this helps someone :)

In fact the "[" square opening bracket is just an internal shell alias for the test command.

So you can say:

test -f "/bin/bash" && echo "This system has a bash shell"

or

[ -f "/bin/bash" ] && echo "This system has a bash shell"

... they are equivalent in either sh or bash. Note the requirement to have a closing "]" bracket on the "[" command but other than that "[" is the same as "test". "man test" is a good thing to read.

In HTML5 there is no scrolling attribute because "its function is better handled by CSS" see http://www.w3.org/TR/html5-diff/ for other changes. Well and the CSS solution:

CSS solution:

HTML4's scrolling="no" is kind of an alias of the CSS's overflow: hidden, to do so it is important to set size attributes width/height:

iframe.noScrolling{
  width: 250px; /*or any other size*/
  height: 300px; /*or any other size*/
  overflow: hidden;
}

Add this class to your iframe and you're done:

<iframe src="http://www.example.com/" class="noScrolling"></iframe>

! IMPORTANT NOTE ! : overflow: hidden for <iframe> is not fully supported by all modern browsers yet(even chrome doesn't support it yet) so for now (2013) it's still better to use Transitional version and use scrolling="no" and overflow:hidden at the same time :)

UPDATE 2020: the above is still true, oveflow for iframes is still not supported by all majors

calling finish in onCreate() will not call onDestroy() directly as @prakash said. The finish() operation will not even begin until you return control to Android.

Calling finish() in onCreate(): onCreate() -> onStart() -> onResume(). If user exit the app will call -> onPause() -> onStop() -> onDestroy()

Calling finish() in onStart() : onCreate() -> onStart() -> onStop() -> onDestroy()

Calling finish() in onResume(): onCreate() -> onStart() -> onResume() -> onPause() -> onStop() -> onDestroy()

For further reference check look at this oncreate continuous after finish & about finish()

Check C:\Users\User path. Change User directory name (may be something different name) from your alphabet to English alphabet. Warning: it is dangerous operation, learn it before changing. Android Studio can not access to AVD throw users\Your alphabet name\.android.

I am a novice and I did it this way:

Create table Name1
(
F_Name varchar(20),
L_Name varchar(20),
Age INTEGER
)

Insert into Name1
Values
('Tom', 'Bombadil', 32),
('Danny', 'Fartman', 43),
('Stephine', 'Belchlord', 33),
('Corry', 'Smallpants', 95)
Go

Update Name1
Set F_Name = CONCAT(F_Name, ' ', L_Name)
Go

Alter Table Name1
Drop column L_Name
Go

Update Table_Name
Set F_Name

Updated with Swift 5 Generally we use three type of Local Notifications

1. Simple Local Notification
2. Local Notification with Action
3. Local Notification with Content

Where you can send simple text notification or with action button and attachment.

Using UserNotifications package in your app, the following example Request for notification permission, prepare and send notification as per user action AppDelegate itself, and use view controller listing different type of local notification test.

AppDelegate

import UIKit
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    let notificationCenter = UNUserNotificationCenter.current()
    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        //Confirm Delegete and request for permission
        notificationCenter.delegate = self
        let options: UNAuthorizationOptions = [.alert, .sound, .badge]
        notificationCenter.requestAuthorization(options: options) {
            (didAllow, error) in
            if !didAllow {
                print("User has declined notifications")
            }
        }

        return true
    }

    func applicationWillResignActive(_ application: UIApplication) {
    }
    func applicationDidEnterBackground(_ application: UIApplication) {
    }
    func applicationWillEnterForeground(_ application: UIApplication) {
    }
    func applicationWillTerminate(_ application: UIApplication) {
    }
    func applicationDidBecomeActive(_ application: UIApplication) {
        UIApplication.shared.applicationIconBadgeNumber = 0
    }


    //MARK: Local Notification Methods Starts here

    //Prepare New Notificaion with deatils and trigger
    func scheduleNotification(notificationType: String) {

        let categoryIdentifire = "Delete Notification Type"
        content.sound = UNNotificationSound.default
        content.body = "This is example how to send " + notificationType
        content.badge = 1
        content.categoryIdentifier = categoryIdentifire

        //Add attachment for Notification with more content
        if (notificationType == "Local Notification with Content")

1. Upload setup.py to drive.
2. Mount the drive.
3. Get the path of setup.py.
4. !python PATH install.

The first numbers of the credit card can be used to approximate the vendor:

• Visa: 49,44 or 47
• Visa electron: 42, 45, 48, 49
• MasterCard: 51
• Amex:34
• Diners: 30, 36, 38
• JCB: 35

Try:

SELECT
    *
FROM
    YourTable
WHERE
    CHAR_LENGTH(Link) > x

rand() % ((highestNumber - lowestNumber) + 1) + lowestNumber

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

This is a little old but should get you started:

None of the existing answers involve using a comparator, and therefore cannot be used in binary trees or for sorting. So I'm just gonna leave this here:

public static int compareIntArrays(int[] a, int[] b) {
    if (a == null) {
        return b == null ? 0 : -1;
    }
    if (b == null) {
        return 1;
    }
    int cmp = a.length - b.length;
    if (cmp != 0) {
        return cmp;
    }
    for (int i = 0; i < a.length; i++) {
        cmp = Integer.compare(a[i], b[i]);
        if (cmp != 0) {
            return cmp;
        }
    }
    return 0;
}

This should be more efficient both for the application and also for the developer.

Add the following class to your web project:

/// <summary>
/// This holds all of the session variables for the site.
/// </summary>
public class SessionCentralized
{
protected internal static void Save<T>(string sessionName, T value)
{
    HttpContext.Current.Session[sessionName] = value;
}

protected internal static T Get<T>(string sessionName)
{
    return (T)HttpContext.Current.Session[sessionName];
}

public static int? WhatEverSessionVariableYouWantToHold
{
    get
    {
        return Get<int?>(nameof(WhatEverSessionVariableYouWantToHold));
    }
    set
    {
        Save(nameof(WhatEverSessionVariableYouWantToHold), value);
    }
}

}

Here is the implementation:

SessionCentralized.WhatEverSessionVariableYouWantToHold = id;

If you want to check the python version in a particular cond environment you can also use conda list python

<input type="text" name="whatever" id="funkystyling" />

Here's the CSS for the image on the left:

#funkystyling {
    background: white url(/path/to/icon.png) left no-repeat;
    padding-left: 17px;
}

And here's the CSS for the image on the right:

#funkystyling {
    background: white url(/path/to/icon.png) right no-repeat;
    padding-right: 17px;
}

<input type="text" name="attendees" id="autocomplete-custom-append">

<script>
  /* AUTOCOMPLETE */

  function init_autocomplete() {

    if (typeof ($.fn.autocomplete) === 'undefined') {
      return;
    }
    // console.log('init_autocomplete');

    var attendees = {
      1: "Shedrack Godson",
      2: "Hellen Thobias Mgeni",
      3: "Gerald Sanga",
      4: "Tabitha Godson",
      5: "Neema Oscar Mracha"
    };

    var countriesArray = $.map(countries, function (value, key) {
      return {
        value: value,
        data: key
      };
    });

    // initialize autocomplete with custom appendTo
    $('#autocomplete-custom-append').autocomplete({
      lookup: countriesArray
    });

  };
</script>

you should use a /d before path as below :

cd /d e:\

Simple, use array_intersect() instead:

$result = array_intersect($array1, $array2);

Install rvm, which manages the ruby versions:

to install rvm use the following command.

 \curl -sSL https://get.rvm.io | bash -s stable
 source ~/.bash_profile
 rvm install ruby-2.1.4

Check ruby versions installed and in use:

rvm list
rvm use --default ruby-2.1.4

From the documentation (help copy-item -full):

-force <SwitchParameter>
    Allows cmdlet to override restrictions such as renaming existing files as long as security is not compromised.

    Required?                    false
    Position?                    named
    Default value                False
    Accept pipeline input?       false
    Accept wildcard characters?  false

If you set unique parameters, then the cache does not work, for example:

$.ajax({
    url : "my_url",
    data : {
        'uniq_param' : (new Date()).getTime(),
        //other data
    }});

CPMSifDlg::EncodeAndSend() method is declared as non-static and thus it must be called using an object of CPMSifDlg. e.g.

CPMSifDlg obj;
return obj.EncodeAndSend(firstName, lastName, roomNumber, userId, userFirstName, userLastName);

If EncodeAndSend doesn't use/relate any specifics of an object (i.e. this) but general for the class CPMSifDlg then declare it as static:

class CPMSifDlg {
...
  static int EncodeAndSend(...);
  ^^^^^^
};

You have to override method handledType and everything will work

@Override
public Class<Item> handledType()
{
  return Item.class;
}

The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.

That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!

<style>
  html, body {
    height: 100%;
  }
  #tableContainer-1 {
    height: 100%;
    width: 100%;
    display: table;
  }
  #tableContainer-2 {
    vertical-align: middle;
    display: table-cell;
    height: 100%;
  }
  #myTable {
    margin: 0 auto;
  }
</style>
<div id="tableContainer-1">
  <div id="tableContainer-2">
    <table id="myTable" border>
      <tr><td>Name</td><td>J W BUSH</td></tr>
      <tr><td>Proficiency</td><td>PHP</td></tr>
      <tr><td>Company</td><td>BLAH BLAH</td></tr>
    </table>
  </div>
</div>

You should check if it's not defined using if (!Array.prototype.indexOf).

Also, your implementation of indexOf is not correct. You must use === instead of == in your if (this[i] == obj) statement, otherwise [4,"5"].indexOf(5) would be 1 according to your implementation, which is incorrect.

I recommend you use the implementation on MDC.

There's also the DateTime class which implements a function for comparison operators.

// $now = new DateTime();
$dtA = new DateTime('05/14/2010 3:00PM');
$dtB = new DateTime('05/14/2010 4:00PM');

if ( $dtA > $dtB ) {
  echo 'dtA > dtB';
}
else {
  echo 'dtA <= dtB';
}

Try this:

SELECT
    'the sqlserver is ' + substring(@@VERSION, 21, 5) AS [sql version]

From the Help:
IsEmpty returns True if the variable is uninitialized, or is explicitly set to Empty; otherwise, it returns False. False is always returned if expression contains more than one variable.
IsEmpty only returns meaningful information for variants.

To check if a cell is empty, you can use cell(x,y) = "".
You might eventually save time by using Range("X:Y").SpecialCells(xlCellTypeBlanks) or xlCellTypeConstants or xlCellTypeFormulas

Remove your "each" and just use:

$('input[name=ticketID]').attr("disabled",true);

That simple. It works

I also faced the same problem, and I could not find any other way but splitting the single SQL operation in separate files, then executing all of them in sequence.

Obviously the problem is not with lists of DML commands, they can be executed without GO in between; different story with DDL (create, alter, drop...)

I use this function (PHP 7)

function getDateForDatabase(string $date): string {
    $timestamp = strtotime($date);
    $date_formated = date('Y-m-d H:i:s', $timestamp);
    return $date_formated;
}

Older versions of PHP (PHP < 7)

function getDateForDatabase($date) {
    $timestamp = strtotime($date);
    $date_formated = date('Y-m-d H:i:s', $timestamp);
    return $date_formated;
}

Windows INI API support for:

• Line comments: yes, using semi-colon ;
• Trailing comments: No

The authoritative source is the Windows API function that reads values out of INI files

GetPrivateProfileString

Retrieves a string from the specified section in an initialization file.

The reason "full line comments" work is because the requested value does not exist. For example, when parsing the following ini file contents:

[Application]
UseLiveData=1
;coke=zero
pepsi=diet   ;gag
#stackoverflow=splotchy

Reading the values:

• UseLiveData: 1
• coke: not present
• ;coke: not present
• pepsi: diet ;gag
• stackoverflow: not present
• #stackoverflow: splotchy

Update: I used to think that the number sign (#) was a pseudo line-comment character. The reason using leading # works to hide stackoverflow is because the name stackoverflow no longer exists. And it turns out that semi-colon (;) is a line-comment.

But there is no support for trailing comments.

Swift 3:

if unknownType is MyClass {
   //unknownType is of class type MyClass
}

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

class ArrLst{

    public static void main(String args[]){

        List l=new ArrayList();
        l.add(10);
        l.add(11);
        l.add(12);
        l.add(13);
        l.add(14);
        l.forEach((a)->System.out.println(a));
    }
}

Like @g-eorge mention, you can make it like this:

module.config(['$routeProvider', function($routeProvider) {
$routeProvider.
  when('/users/:userId?', {templateUrl: 'template.tpl.html', controller: myCtrl})
}]);

You can also make as much as u need optional parameters.

I start standalone instance in my machine, and encounter the same problem. Finally, I change from ip "127.0.0.1" to "localhost" and the problem is gone.

You put it as =(B0+4)/($A$0)

You can also go across WorkSheets with Sheet1!$a$0

If you can count on having a period of time where the table is in a stable state with no new inserts going on, this should do it (untested):

DECLARE
  last_used  NUMBER;
  curr_seq   NUMBER;
BEGIN
  SELECT MAX(pk_val) INTO last_used FROM your_table;

  LOOP
    SELECT your_seq.NEXTVAL INTO curr_seq FROM dual;
    IF curr_seq >= last_used THEN EXIT;
    END IF;
  END LOOP;
END;

This enables you to get the sequence back in sync with the table, without dropping/recreating/re-granting the sequence. It also uses no DDL, so no implicit commits are performed. Of course, you're going to have to hunt down and slap the folks who insist on not using the sequence to populate the column...

It's working with me :

echo Auth::guard('guard_name')->user()->id;

The actual walk through the directories works as you have coded it. If you replace the contents of the inner loop with a simple print statement you can see that each file is found:

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print os.path.join(subdir, file)

If you still get errors when running the above, please provide the error message.

Updated for Python3

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print(os.path.join(subdir, file))

About this I think you can reference to http://docs.oasis-open.org/security/saml/Post2.0/sstc-saml-tech-overview-2.0.html.

Here're my understandings about this, with the Identity Federation Use Case to give a details for those concepts:

• Persistent identifiers-

IdP provides the Persistent identifiers, they are used for linking to the local accounts in SPs, but they identify as the user profile for the specific service each alone. For example, the persistent identifiers are kind of like : johnForAir, jonhForCar, johnForHotel, they all just for one specified service, since it need to link to its local identity in the service.

• Transient identifiers-

Transient identifiers are what IdP tell the SP that the users in the session have been granted to access the resource on SP, but the identities of users do not offer to SP actually. For example, The assertion just like “Anonymity(Idp doesn’t tell SP who he is) has the permission to access /resource on SP”. SP got it and let browser to access it, but still don’t know Anonymity' real name.

• unspecified identifiers-

The explanation for it in the spec is "The interpretation of the content of the element is left to individual implementations". Which means IdP defines the real format for it, and it assumes that SP knows how to parse the format data respond from IdP. For example, IdP gives a format data "UserName=XXXXX Country=US", SP get the assertion, and can parse it and extract the UserName is "XXXXX".

If your project is on GitHub, you now (April 2013) have Pulse (see "Get up to speed with Pulse"):

It is more limited, and won't display all the stats you might need, but is readily available for any GitHub project.

Pulse is a great way to discover recent activity on projects.
Pulse will show you who has been actively committing and what has changed in a project's default branch:

You can find the link to the left of the nav bar.

Note that there isn't (yet) an API to extract that information.

This regex pattern will match an empty string:

^$

And this will match (crudely) an email or an empty string:

(^$|^.*@.*\..*$)

Use jQuery.attr() in your click handler:

$("#myform").attr('action', 'page1.php');

Turns out you don't have to do much at all.

See below - the parameter x will contain the full HTTP body (which is XML in our case).

@POST
public Response go(String x) throws IOException {
    ...
}

Doxygen or Sandcastle help file builder are the primary tools that will extract XML documentation into HTML (and other forms) of external documentation.

Note that you can combine these documentation exporters with documentation generators - as you've discovered, Resharper has some rudimentary helpers, but there are also much more advanced tools to do this specific task, such as GhostDoc (for C#/VB code with XML documentation) or my addin Atomineer Pro Documentation (for C#, C++/CLI, C++, C, VB, Java, JavaScript, TypeScript, JScript, PHP, Unrealscript code containing XML, Doxygen, JavaDoc or Qt documentation).

This behavior is related to Zone that is set - Internet/Intranet/etc and corresponding Security Level

You can change this by setting less secure Security Level (not recommended) or by customizing Display Mixed Content property

You can do that by following steps:

1. Click on Gear icon at the top of the browser window.
2. Select Internet Options.
3. Select the Security tab at the top.
4. Click the Custom Level... button.
5. Scroll about halfway down to the Miscellaneous heading (denoted by a "blank page" icon).
6. Under this heading is the option Display Mixed Content; set this to Enable/Prompt.
7. Click OK, then Yes when prompted to confirm the change, then OK to close the Options window.
8. Close and restart the browser.

This is a simple way of doing something.

    @Override
        public void onBackPressed() {
            // do what you want to do when the "back" button is pressed.
            startActivity(new Intent(Activity.this, MainActivity.class));
            finish();
        }

I think there might be more elaborate ways of going about it, but I like simplicity. For example, I used the template above to make the user sign out of the application AND THEN go back to another activity of my choosing.

Best answer Maverick 1st's correctly translated to Swift (working with latest swift 3):

func imageWithImage (sourceImage:UIImage, scaledToWidth: CGFloat) -> UIImage {
    let oldWidth = sourceImage.size.width
    let scaleFactor = scaledToWidth / oldWidth

    let newHeight = sourceImage.size.height * scaleFactor
    let newWidth = oldWidth * scaleFactor

    UIGraphicsBeginImageContext(CGSize(width:newWidth, height:newHeight))
    sourceImage.draw(in: CGRect(x:0, y:0, width:newWidth, height:newHeight))
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return newImage!
}

There is a third recovery mode not mentioned above. The recovery mode ultimately determines how large the LDF files become and how ofter they are written to. In cases where you are going to be doing any type of bulk inserts, you should set the DB to be in "BULK/LOGGED". This makes bulk inserts move speedily along and can be changed on the fly.

To do so,

USE master ;
ALTER DATABASE model SET RECOVERY BULK_LOGGED ;

To change it back:

USE master ;
ALTER DATABASE model SET RECOVERY FULL ;

In the spirit of adding to the conversation about why someone would not want an LDF, I add this: We do multi-dimensional modelling. Essentially we use the DB as a large store of variables that are processed in bulk using external programs. We do not EVER require rollbacks. If we could get a performance boost by turning of ALL logging, we'd take it in a heart beat.

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override
            public Class getColumnClass(int column) {
            return getValueAt(0, column).getClass();
            }*/
            @Override
            public Class getColumnClass(int column) {
                switch (column) {
                    case 0:
                        return String.class;
                    case 1:
                        return String.class;
                    case 2:
                        return Integer.class;
                    case 3:
                        return Double.class;
                    default:
                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}

I got the same issue while adding dynamic url in Image tag in Angular 7. I searched a lot and found this solution.

First, write below code in the component file.

constructor(private sanitizer: DomSanitizer) {}
public getSantizeUrl(url : string) {
    return this.sanitizer.bypassSecurityTrustUrl(url);
}

Now in your html image tag, you can write like this.

<img class="image-holder" [src]=getSantizeUrl(item.imageUrl) />

You can write as per your requirement instead of item.imageUrl

I got a reference from this site.dynamic urls. Hope this solution will help you :)

The simplest solution would be (using 'upstream' as the remote name referencing the original repo forked):

git remote add upstream /url/to/original/repo
git fetch upstream
git checkout master
git reset --hard upstream/master  
git push origin master --force 

(Similar to this GitHub page, section "What should I do if I’m in a bad situation?")

Be aware that you can lose changes done on the master branch (both locally, because of the reset --hard, and on the remote side, because of the push --force).

An alternative would be, if you want to preserve your commits on master, to replay those commits on top of the current upstream/master.
Replace the reset part by a git rebase upstream/master. You will then still need to force push.
See also "What should I do if I’m in a bad situation?"

A more complete solution, backing up your current work (just in case) is detailed in "Cleanup git master branch and move some commit to new branch".

See also "Pull new updates from original GitHub repository into forked GitHub repository" for illustrating what "upstream" is.

Note: recent GitHub repos do protect the master branch against push --force.
So you will have to un-protect master first (see picture below), and then re-protect it after force-pushing).

Note: on GitHub specifically, there is now (February 2019) a shortcut to delete forked repos for pull requests that have been merged upstream.

In Swift 4:

let formatString = "12345"
if let number = Decimal(string:formatString){

    print("String contains only number")
}
else{
    print("String doesn't contains only number")
}

This code works very fast. It comes from here

Not with a regular statement, no.

What you can do is wrap the functionality in a PL/pgsql function (or another language, but PL/pgsql seems to be the most appropriate for this), and then just call that function. That means it'll still be a single statement to your app.

The field's value is:

 "- DE-HEB 20% - DTopTen 1.2%"
SELECT ....
SUBSTRING_INDEX(SUBSTRING_INDEX(DesctosAplicados, 'DE-HEB ',  -1), '-', 1) DE-HEB ,
SUBSTRING_INDEX(SUBSTRING_INDEX(DesctosAplicados, 'DTopTen ',  -1), '-', 1) DTopTen ,

FROM TABLA 

Result is:

  DE-HEB       DTopTEn
    20%          1.2%

delete performs the check anyway, so checking it on your side adds overhead and looks uglier. A very good practice is setting the pointer to NULL after delete (helps avoiding double deletion and other similar memory corruption problems).

I'd also love if delete by default was setting the parameter to NULL like in

#define my_delete(x) {delete x; x = NULL;}

(I know about R and L values, but wouldn't it be nice?)

Ray's solution is good. However, on my machine it is about 2.5x faster to use numpy.sum in place of numpy.min:

In [13]: %timeit np.isnan(np.min(x))
1000 loops, best of 3: 244 us per loop

In [14]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 97.3 us per loop

Unlike min, sum doesn't require branching, which on modern hardware tends to be pretty expensive. This is probably the reason why sum is faster.

edit The above test was performed with a single NaN right in the middle of the array.

It is interesting to note that min is slower in the presence of NaNs than in their absence. It also seems to get slower as NaNs get closer to the start of the array. On the other hand, sum's throughput seems constant regardless of whether there are NaNs and where they're located:

In [40]: x = np.random.rand(100000)

In [41]: %timeit np.isnan(np.min(x))
10000 loops, best of 3: 153 us per loop

In [42]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 95.9 us per loop

In [43]: x[50000] = np.nan

In [44]: %timeit np.isnan(np.min(x))
1000 loops, best of 3: 239 us per loop

In [45]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 95.8 us per loop

In [46]: x[0] = np.nan

In [47]: %timeit np.isnan(np.min(x))
1000 loops, best of 3: 326 us per loop

In [48]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 95.9 us per loop

            FileOutputStream fos = Main.this.openFileOutput("exported_data.csv", MODE_WORLD_READABLE);
            fos.write(csv.getBytes());
            fos.close();
            File file = Main.this.getFileStreamPath("exported_data.csv");
            return file.getAbsolutePath();
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }

Your container does not have a height.

Add height: 200px;

to the containers css and the kitty will stay inside.

childView.bringToFront() didn't work for me, so I set the Z translation of the least recently added item (the one that was overlaying all other children) to a negative value like so:

lastView.setTranslationZ(-10);

see https://developer.android.com/reference/android/view/View.html#setTranslationZ(float) for more

The button isn't inside the input. Here:

input[type="text"] {
    width: 200px;
    height: 20px;
    padding-right: 50px;
}

input[type="submit"] {
    margin-left: -50px;
    height: 20px;
    width: 50px;
}

You could use streams in Java 8. To always get 10 entries at the most, you could do:

dataList.stream().skip(5).limit(10).collect(Collectors.toList());
dataList.stream().skip(30).limit(10).collect(Collectors.toList());

I know this was asked a long time ago and now there's a new UIButtonTypeSystem. But newer questions are being marked as duplicates of this question so here's my newer answer in the context of an iOS 7 system button, use the .tintColor property.

let button = UIButton(type: .System)
button.setTitle("My Button", forState: .Normal)
button.tintColor = .redColor()

You can now do this by including the sound when building a notification rather than calling the sound separately.

//Define Notification Manager
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

//Define sound URI
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext())
        .setSmallIcon(icon)
        .setContentTitle(title)
        .setContentText(message)
        .setSound(soundUri); //This sets the sound to play

//Display notification
notificationManager.notify(0, mBuilder.build());

Before using multidimensional arrays in Swift, consider their impact on performance. In my tests, the flattened array performed almost 2x better than the 2D version:

var table = [Int](repeating: 0, count: size * size)
let array = [Int](1...size)
for row in 0..<size {
    for column in 0..<size {
        let val = array[row] * array[column]
        // assign
        table[row * size + column] = val
    }
}

Average execution time for filling up a 50x50 Array: 82.9ms

vs.

var table = [[Int]](repeating: [Int](repeating: 0, count: size), count: size)
let array = [Int](1...size)
for row in 0..<size {
    for column in 0..<size {
        // assign
        table[row][column] = val
    }
}

Average execution time for filling up a 50x50 2D Array: 135ms

Both algorithms are O(n^2), so the difference in execution times is caused by the way we initialize the table.

Finally, the worst you can do is using append() to add new elements. That proved to be the slowest in my tests:

var table = [Int]()    
let array = [Int](1...size)
for row in 0..<size {
    for column in 0..<size {
        table.append(val)
    }
}

Average execution time for filling up a 50x50 Array using append(): 2.59s

Conclusion

Avoid multidimensional arrays and use access by index if execution speed matters. 1D arrays are more performant, but your code might be a bit harder to understand.

You can run the performance tests yourself after downloading the demo project from my GitHub repo: https://github.com/nyisztor/swift-algorithms/tree/master/big-o-src/Big-O.playground

Dimension a variable, basically you are telling the compiler that you are going to need a variable of this type at some point.

1. Creation and initialization

   Object[] yourArray = new Object[ARRAY_LENGTH];
   

2. Write access

   yourArray[i]= someArrayList;
   

   to access elements of internal ArrayList:

   ((ArrayList<YourType>) yourArray[i]).add(elementOfYourType); //or other method
   

3. Read access

   to read array element i as an ArrayList use type casting:

   someElement= (ArrayList<YourType>) yourArray[i];
   

   for array element i: to read ArrayList element at index j

   arrayListElement= ((ArrayList<YourType>) yourArray[i]).get(j);
   

add like

<head runat="server">
<script src="Registration.js" type="text/javascript"></script>
</head>

OR can add in code behind.

Page.ClientScript.RegisterClientScriptInclude("Registration", ResolveUrl("~/js/Registration.js"));

Your null pointer exception seems to be on this line:

String url = intent.getExtras().getString("userurl");

because intent.getExtras() returns null when the intent doesn't have any extras.

You have to realize that this piece of code:

Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);

doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass and if that doesn't exist, your app crashes.

Also, there is no such thing as "android.intent.action.start" so the manifest should look more like:

<activity android:name=".start" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity android:name= ".Main">
</activity>

I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

Learn them and slowly you'll be able to reconize and figure out when to use them. Start with something simple as the singleton pattern :)

if you want to create one instance of an object and just ONE. You use the singleton pattern. Let's say you're making a program with an options object. You don't want several of those, that would be silly. Singleton makes sure that there will never be more than one. Singleton pattern is simple, used a lot, and really effective.

I don't believe the currently accepted answer is correct. For example, I have the following .htaccess file in the root of a virtual server (apache 2.4):

<Files "reminder.php">
require all denied
require host localhost
require ip 127.0.0.1
require ip xxx.yyy.zzz.aaa
</Files>

This prevents external access to reminder.php which is in a subdirectory. I have a similar .htaccess file on my Apache 2.2 server with the same effect:

<Files "reminder.php">
        Order Deny,Allow
        Deny from all
        Allow from localhost
        Allow from 127.0.0.1
     Allow from xxx.yyy.zzz.aaa
</Files>

I don't know for sure but I suspect it's the attempt to define the subdirectory specifically in the .htaccess file, viz <Files ./inscription/log.txt> which is causing it to fail. It would be simpler to put the .htaccess file in the same directory as log.txt i.e. in the inscription directory and it will work there.

To expand on the Wikipedia-based answers:

The Social Security Administration (SSA) explicitly states in this document that the having "000" in the first group of numbers "will NEVER be a valid SSN":

• http://www.socialsecurity.gov/employer/stateweb.htm

I'd consider that pretty definitive.

However, that the 2nd or 3rd groups of numbers won't be "00" or "0000" can be inferred from a FAQ that the SSA publishes which indicates that allocation of those groups starts at "01" or "0001":

• http://ssa-custhelp.ssa.gov/cgi-bin/ssa.cfg/php/enduser/std_adp.php?p_faqid=87

But this is only a FAQ and it's never outright stated that "00" or "0000" will never be used.

In another FAQ they provide (http://www.socialsecurity.gov/employer/randomizationfaqs.html#a0=6) that "00" or "0000" will never be used.

I can't find a reference to the 'advertisement' reserved SSNs on the SSA site, but it appears that no numbers starting with a 3 digit number higher than 772 (according to the document referenced above) have been assigned yet, but there's nothing I could find that states those numbers are reserved. Wikipedia's reference is a book that I don't have access to. The Wikipedia information on the advertisement reserved numbers is mentioned across the web, but many are clearly copied from Wikipedia. I think it would be nice to have a citation from the SSA, though I suspect that now that Wikipedia has made the idea popular that these number would now have to be reserved for advertisements even if they weren't initially.

The SSA has a page with a couple of stories about SSN's they've had to retire because they were used in advertisements/samples (maybe the SSA should post a link to whatever their current policy on this might be):

• http://www.ssa.gov/history/ssn/misused.html

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.

Here It is actually returning tuple.

If you execute this code in Python 3:

def get():
    a = 3
    b = 5
    return a,b
number = get()
print(type(number))
print(number)

Output :

<class 'tuple'>
(3, 5)

But if you change the code line return [a,b] instead of return a,b and execute :

def get():
    a = 3
    b = 5
    return [a,b]
number = get()
print(type(number))
print(number)

Output :

<class 'list'>
[3, 5]

It is only returning single object which contains multiple values.

There is another alternative to return statement for returning multiple values, use yield( to check in details see this What does the "yield" keyword do in Python?)

Sample Example :

def get():
    for i in range(5):
        yield i
number = get()
print(type(number))
print(number)
for i in number:
    print(i)

Output :

<class 'generator'>
<generator object get at 0x7fbe5a1698b8>
0
1
2
3
4

It is because of conflicting SID. For example, in your Oracle12cBase\app\product\12.1.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora file, connection description for ORCL is this:

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

And, you are trying to connect using the connection string using same SID but different IP, username/password, like this:

sqlplus username/[email protected]:1521/orcl

To resolve this, make changes in the tnsnames.ora file:

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.130.52)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

Another option for you is a linked list. You'll need to analyze how your program will use the data structure, if you don't need random access it could be faster than reallocating.

After some research, I think the best answer is Xerces, as it implements all of XSD, is cross-platform and widely used. I've created a small Java project on github to validate from the command line using the default JRE parser, which is normally Xerces. This can be used on Windows/Mac/Linux.

There is also a C++ version of Xerces available if you'd rather use that. The StdInParse utility can be used to call it from the command line. Also, a commenter below points to this more complete wrapper utility.

You could also use xmllint, which is part of libxml. You may well already have it installed. Example usage:

xmllint --noout --schema XSD_FILE XML_FILE

One problem is that libxml doesn't implement all of the specification, so you may run into issues :(

Alternatively, if you are on Windows, you can use msxml, but you will need some sort of wrapper to call it, such as the GUI one described in this DDJ article. However, it seems most people on Windows use an XML Editor, such as Notepad++ (as described in Nate's answer) or XML Notepad 2007 as suggested by SteveC (there are also several commercial editors which I won't mention here).

Finally, you'll find different programs will, unfortunately, give different results. This is largely due to the complexity of the XSD spec. You may want to test your schema with several tools.

UPDATE: I've expanded on this in a blog post.

That entire block is misplaced.

class Example(object):
    def main(self):     
        print "Hello World!"

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

But you really shouldn't be using a class just to run your main code.

Servlet-mapping has two child tags, url-pattern and servlet-name. url-pattern specifies the type of urls for which, the servlet given in servlet-name should be called. Be aware that, the container will use case-sensitive for string comparisons for servlet matching.

First specification of url-pattern a web.xml file for the server context on the servlet container at server .com matches the pattern in <url-pattern>/status/*</url-pattern> as follows:

http://server.com/server/status/synopsis               = Matches
http://server.com/server/status/complete?date=today    = Matches
http://server.com/server/status                        = Matches
http://server.com/server/server1/status                = Does not match

Second specification of url-pattern A context located at the path /examples on the Agent at example.com matches the pattern in <url-pattern>*.map</url-pattern> as follows:

 http://server.com/server/US/Oregon/Portland.map    = Matches
 http://server.com/server/US/server/Seattle.map     = Matches
 http://server.com/server/Paris.France.map          = Matches
 http://server.com/server/US/Oregon/Portland.MAP    = Does not match, the extension is uppercase
 http://example.com/examples/interface/description/mail.mapi  =Does not match, the extension is mapi rather than map`

Third specification of url-mapping,A mapping that contains the pattern <url-pattern>/</url-pattern> matches a request if no other pattern matches. This is the default mapping. The servlet mapped to this pattern is called the default servlet.

The default mapping is often directed to the first page of an application. Explicitly providing a default mapping also ensures that malformed URL requests into the application return are handled by the application rather than returning an error.

The servlet-mapping element below maps the server servlet instance to the default mapping.

<servlet-mapping>
  <servlet-name>server</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

For the context that contains this element, any request that is not handled by another mapping is forwarded to the server servlet.

And Most importantly we should Know about Rule for URL path mapping

1. The container will try to find an exact match of the path of the request to the path of the servlet. A successful match selects the servlet.
2. The container will recursively try to match the longest path-prefix. This is done by stepping down the path tree a directory at a time, using the ’/’ character as a path separator. The longest match determines the servlet selected.
3. If the last segment in the URL path contains an extension (e.g. .jsp), the servlet container will try to match a servlet that handles requests for the extension. An extension is defined as the part of the last segment after the last ’.’ character.
4. If neither of the previous three rules result in a servlet match, the container will attempt to serve content appropriate for the resource requested. If a “default” servlet is defined for the application, it will be used.

Reference URL Pattern

         select date 'now()' - date '1955-12-15';

Here is the simple query which calculates total no of days.

Lets look at ways to reference the image.

Back a directory

../

Folder in a directory:

 foldername/

File in a directory

 imagename.jpg

Now, lets combine them with the addresses you specified.

 /Resources/views/Default/index.html
 /Resources/public/images/iwojimaflag.jpg

The first common directory referenced from the html file is three back:

 ../../../

It is in within two folders in that:

 ../../../public/images/

And you've reached the image:

 ../../../public/images/iwojimaflag.jpg

Note: This is assuming you are accessing a page at domain.com/Resources/views/Default/index.html as you specified in your comment.

#include <iostream>
#include <iomanip>
using namespace std;

You can enter the line using namespace std; for your convenience. Otherwise, you'll have to explicitly add std:: every time you wish to use cout, fixed, showpoint, setprecision(2) and endl

int main()
{
    double num1 = 3.12345678;
    cout << fixed << showpoint;
    cout << setprecision(2);
    cout << num1 << endl;
return 0;
}

It's not that much work to make a function that's allocating the needed memory for your string. That's a little c-function i wrote some time ago, i always use it to read in strings.

It will return the read string or if a memory error occurs NULL. But be aware that you have to free() your string and always check for it's return value.

#define BUFFER 32

char *readString()
{
    char *str = malloc(sizeof(char) * BUFFER), *err;
    int pos;
    for(pos = 0; str != NULL && (str[pos] = getchar()) != '\n'; pos++)
    {
        if(pos % BUFFER == BUFFER - 1)
        {
            if((err = realloc(str, sizeof(char) * (BUFFER + pos + 1))) == NULL)
                free(str);
            str = err;
        }
    }
    if(str != NULL)
        str[pos] = '\0';
    return str;
}

Generally, it is assumed that name is always superseded by id. This is true, to some extent, but not for form fields and frame names, practically speaking. For example, with form elements the name attribute is used to determine the name-value pairs to be sent to a server-side program and should not be eliminated. Browsers do not use id in that manner. To be on the safe side, you could use name and id attributes on form elements. So, we would write the following:

<form id="myForm" name="myForm">
     <input type="text" id="userName" name="userName" />
</form>

To ensure compatibility, having matching name and id attribute values when both are defined is a good idea. However, be careful—some tags, particularly radio buttons, must have nonunique name values, but require unique id values. Once again, this should reference that id is not simply a replacement for name; they are different in purpose. Furthermore, do not discount the old-style approach, a deep look at modern libraries shows such syntax style used for performance and ease purposes at times. Your goal should always be in favor of compatibility.

Now in most elements, the name attribute has been deprecated in favor of the more ubiquitous id attribute. However, in some cases, particularly form fields (<button>, <input>, <select>, and <textarea>), the name attribute lives on because it continues to be required to set the name-value pair for form submission. Also, we find that some elements, notably frames and links, may continue to use the name attribute because it is often useful for retrieving these elements by name.

There is a clear distinction between id and name. Very often when name continues on, we can set the values the same. However, id must be unique, and name in some cases shouldn’t—think radio buttons. Sadly, the uniqueness of id values, while caught by markup validation, is not as consistent as it should be. CSS implementation in browsers will style objects that share an id value; thus, we may not catch markup or style errors that could affect our JavaScript until runtime.

This is taken from the book JavaScript- The Complete Reference by Thomas-Powell

In my case it was not anything that could be fixed with php artisan commands. The issue was folder permissions for the /storage folder. The error did not make that clear.

I encountered the same issue. I think another way to fix this is that you can change the query to join fetch your Element from Model as follows:

Query query = session.createQuery("from Model m join fetch m.element where modelGroup.id = :modelGroupId")

First Program with comments

#include <stdio.h>

int main(){
    int *ptr;             //Create a pointer that points to random memory address

    *ptr = 20;            //Dereference that pointer, 
                          // and assign a value to random memory address.
                          //Depending on external (not inside your program) state
                          // this will either crash or SILENTLY CORRUPT another 
                          // data structure in your program.  

    printf("%d", *ptr);   //Print contents of same random memory address
                          // May or may not crash, depending on who owns this address

    return 0;             
}

Second Program with comments

#include <stdio.h>

int main(){
    int *ptr;              //Create pointer to random memory address

    int q = 50;            //Create local variable with contents int 50

    ptr = &q;              //Update address targeted by above created pointer to point
                           // to local variable your program properly created

    printf("%d", *ptr);    //Happily print the contents of said local variable (q)
    return 0;
}

The key is you cannot use a pointer until you know it is assigned to an address that you yourself have managed, either by pointing it at another variable you created or to the result of a malloc call.

Using it before is creating code that depends on uninitialized memory which will at best crash but at worst work sometimes, because the random memory address happens to be inside the memory space your program already owns. God help you if it overwrites a data structure you are using elsewhere in your program.

Short answer:
install Remote Server Administration tools on your SQL Server (it's an optional feature of Windows Server), reboot, then run SQL Server configuration manager, access the service settings for each of the services whose logon account starts with "NT Service...", clear out the password fields and restart the service. Under the covers, SQL Server Config manager will assign these virtual accounts the Log On as a Service right, and you'll be on your way.

tl;dr;

There is a catch-22 between default settings for a windows domain and default install of SQL Server 2012.

As mentioned above, default Windows domain setup will indeed prevent you from defining the "log on as a service" right via Group Policy Edit at the local machine (via GUI at least; if you install Powershell ActiveDirectory module (via Remote Server Administration tools download) you can do it by scripting.

And, by default, SQL Server 2012 setup runs services in "virtual accounts" (NT Service\ prefix, e.g, NT Service\MSSQLServer. These are like local machine accounts, not domain accounts, but you still can't assign them log on as service rights if your server is joined to a domain. SQL Server setup attempts to assign the right at install, and the SQL Server Config Management tool likewise attempts to assign the right when you change logon account.

And the beautiful catch-22 is this: SQL Server tools depend on (some component of) RSAT to assign the logon as service right. If you don't happen to have RSAT installed on your member server, SQL Server Config Manager fails silently trying to apply the setting (despite all the gaudy pre-installation verification it runs) and you end up with services that won't start.

The one hint of this requirement that I was able to find in the blizzard of SQL Server and Virtual Account doc was this: https://msdn.microsoft.com/en-us/library/ms143504.aspx#New_Accounts, search for RSAT.

With SQL Server 2012 and onward you can use the FORMAT function

SELECT FORMAT(GETDATE(), 'dddd')

With webpack you can put env-specific config into the externals field in webpack.config.js

externals: {
  'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? {
    serverUrl: "https://myserver.com"
  } : {
    serverUrl: "http://localhost:8090"
  })
}

If you want to store the configs in a separate JSON file, that's possible too, you can require that file and assign to Config:

externals: {
  'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? require('./config.prod.json') : require('./config.dev.json'))
}

Then in your modules, you can use the config:

var Config = require('Config')
fetchData(Config.serverUrl + '/Enterprises/...')

For React:

import Config from 'Config';
axios.get(this.app_url, {
        'headers': Config.headers
        }).then(...);

Not sure if it covers your use case but it's been working pretty well for us.

This is a known issue in Chrome and resolved in latest versions. Please refer https://bugs.chromium.org/p/chromium/issues/detail?id=942440 for more details.

Extract single value from JSON response Python

Try this

import json
import sys

#load the data into an element
data={"test1" : "1", "test2" : "2", "test3" : "3"}

#dumps the json object into an element
json_str = json.dumps(data)

#load the json to a string
resp = json.loads(json_str)

#print the resp
print (resp)

#extract an element in the response
print (resp['test1'])

Not out of the box in Sql Server Management Studio, but it is a feature of the very good SSMS Tools Pack

I like doing:

 
var menu = document.getElementsByTagName('div');
for (var i = 0; menu[i]; i++) {
     ...
}

There is no call to the length of the array on every iteration.

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

From DateTime on msdn:

Type: System.DateTime% When this method returns, contains the DateTime value equivalent to the date and time contained in s, if the conversion succeeded, or MinValue if the conversion failed. The conversion fails if the s parameter is null, is an empty string (""), or does not contain a valid string representation of a date and time. This parameter is passed uninitialized.

Use parseexact with the format string "yyyy-dd-MM hh:mm tt" instead.

Geckofx and Webkit.net were both promising at first, but they didn't keep up to date with Firefox and Chrome respectively while as Internet Explorer improved, so did the Webbrowser control, though it behaves like IE7 by default regardless of what IE version you have but that can be fixed by going into the registry and change it to IE9 allowing HTML5.

You want  win.Sleep(milliseconds), methinks.

Yeah, you definitely don't want to do a busy-wait like you describe.
