Another approach to test just for a JSON response (not that the content within contains an expected value), is to parse the response using ActiveSupport:

ActiveSupport::JSON.decode(response.body).should_not be_nil

If the response is not parsable JSON an exception will be thrown and the test will fail.

My test results:

callto:

• Nokia Browser: nothing happens
• Google Chrome: asks to run skype to call the number
• Firefox: asks to choose a program to call the number
• IE: asks to run skype to call the number

tel:

• Nokia Browser: working
• Google Chrome: nothing happens
• Firefox: "Firefox doesnt know how to open this url"
• IE: could not find url

I've used the following with jQuery UI Dialog. (Maybe it works with other ajax callbacks?)

$('<div><img src="/i/loading.gif" id="loading" /></div>').load('/ajax.html').dialog({
    height: 300,
    width: 600,
    title: 'Wait for it...'
});

The contains an animated loading gif until its content is replaced when the ajax call completes.

Easy task using stringByReplacingOccurrencesOfString

NSString *search = [searchbar.text stringByReplacingOccurrencesOfString:@" " withString:@""];

set vimdiff to ignore case

Having started vim diff with

 gvim -d main.sql backup.sql &

I find that annoyingly one file has MySQL keywords in lowercase the other uppercase showing differences on practically every other line

:set diffopt+=icase

this updates the screen dynamically & you can just as easily switch it off again

You can rewrite it to use the ELSE condition of a CASE:

SELECT status,
       CASE status
         WHEN 'i' THEN 'Inactive'
         WHEN 't' THEN 'Terminated'
         ELSE 'Active'
       END AS StatusText

Xcode Version 11.0:

I recently upgraded to Xcode Version 11.0.

Looks like Apple moved the Signing to a new tab from the original General tab.

1. Navigate to the application
2. Select "Signing & Capabilities"
3. Click "Enable Development Signing"

ok i figure out :

DECLARE @dayName VARCHAR(9), @weekenda VARCHAR(9), @free INT
SET @weekenda =DATENAME(dw,GETDATE())

IF (@weekenda='Saturday' OR @weekenda='Sunday')
SET @free=1
ELSE
SET @free=0

than i use : .......... OR free=1

You could use a Filter and do the following test:

HttpSession session = request.getSession(false);// don't create if it doesn't exist
if(session != null && !session.isNew()) {
    chain.doFilter(request, response);
} else {
    response.sendRedirect("/login.jsp");
}

The above code is untested.

This isn't the most extensive solution however. You should also test that some domain-specific object or flag is available in the session before assuming that because a session isn't new the user must've logged in. Be paranoid!

this is the correct answer

$('#theid').css('display') == 'none'

You can also use following line to find if it is display block or none

$('.deal_details').is(':visible')

if the absolute element has a width,you can use the code below

.divtagABS{
    width:300px;
    positon:absolute;
    left:0;
    right:0;
    margin:0 auto;
}

A classpath is a list of locations to load classes from.

These 'locations' can either be directories, or jar files.

For directories, the JVM will follow an expected pattern for loading a class. If I have the directory C:/myproject/classes in my classpath, and I attempt to load a class com.mycompany.Foo, it will look under the classes directory for a directory called com, then under that a directory called mycompany, and finally it will look for a file called Foo.class in that directory.

In the second instance, for jar files, it will search the jar file for that class. A jar file is in reality just a zipped collection of directories like the above. If you unzip a jar file, you'll get a bunch of directories and class files following the pattern above.

So the JVM traverses a classpath from start to finish looking for the definition of the class when it attempts to load the class definition. For example, in the classpath :

C:/myproject/classes;C:/myproject/lib/stuff.jar;C:/myproject/lib/otherstuff.jar

The JVM will attempt to look in the directory classes first, then in stuff.jar and finally in otherstuff.jar.

When you get a ClassNotFoundException, it means the JVM has traversed the entire classpath and not found the class you've attempted to reference. The solution, as so often in the Java world, is to check your classpath.

You define a classpath on the command line by saying java -cp and then your classpath. In an IDE such as Eclipse, you'll have a menu option to specify your classpath.

For Ubntu Users

 1. Install compilers
    #sudo apt-get install make
    #sudo apt-get install gcc

    2. Install openssl and development libraries
    #sudo apt-get install openssl

My two cents for Xcode 8:

a) A custom flag using the -D prefix works fine, but...

b) Simpler use:

In Xcode 8 there is a new section: "Active Compilation Conditions", already with two rows, for debug and release.

Simply add your define WITHOUT -D.

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.

This works for me with Guzzle 6.2 :

$gClient =  new \GuzzleHttp\Client(['base_uri' => 'www.foo.bar']);
$res = $gClient->post('ws/endpoint',
                            array(
                                'headers'=>array('Content-Type'=>'application/json'),
                                'json'=>array('someData'=>'xxxxx','moreData'=>'zzzzzzz')
                                )
                    );

According to the documentation guzzle do the json_encode

Try like this,

jQuery('.leaderMultiSelctdropdown').select2('data');

Use the formula by tigeravatar:

=COUNTIF($B$2:$B$5,A2)>0 – tigeravatar Aug 28 '13 at 14:50

as conditional formatting. Highlight column A. Choose conditional formatting by forumula. Enter the formula (above) - this finds values in col B that are also in A. Choose a format (I like to use FILL and a bold color).

To find all of those values, highlight col A. Data > Filter and choose Filter by color.

TLS (Transport Level Security) is the slightly broader term that has replaced SSL (Secure Sockets Layer) in securing HTTP communications. So what you are being asked to do is enable SSL.

This is as close as I can get to the natural feel of Python's "in" operator. You have to define your own type. Then you can extend the functionality of that type by adding a method like "has" which behaves like you'd hope.

package main

import "fmt"

type StrSlice []string

func (list StrSlice) Has(a string) bool {
    for _, b := range list {
        if b == a {
            return true
        }
    }
    return false
}

func main() {
    var testList = StrSlice{"The", "big", "dog", "has", "fleas"}

    if testList.Has("dog") {
        fmt.Println("Yay!")
    }
}

I have a utility library where I define a few common things like this for several types of slices, like those containing integers or my own other structs.

Yes, it runs in linear time, but that's not the point. The point is to ask and learn what common language constructs Go has and doesn't have. It's a good exercise. Whether this answer is silly or useful is up to the reader.

The namespace in your config should reflect the rest of the namespace path after your client's default namespace (as configured in the project properties). Based on your posted answer, my guess is that your client is configured to be in the "Fusion.DataExchange.Workflows" namespace. If you moved the client code to another namespace you would need to update the config to match the remaining namespace path.

Run this command :

    sudo chown -R yourUser /home/yourUser/.composer

Ref. @Dave's comment on @Dhiraj's answer; an alternative is to use the callback functionality of the ref attribute on the element being rendered (after a component first renders):

<input ref={ function(component){ React.findDOMNode(component).focus();} } />

More info

Sould look like:

<td colspan ='4'><img src="\Pics\H.gif" alt="" border='3' height='100' width='100' /></td>

.

<td> need to be closed with </td> <img /> is (in most case) an empty tag. The closing tag is replacede by /> instead... like for br's

<br/>

Your html structure is plain worng (sorry), but this will probably turn into a really bad cross-brwoser compatibility. Also, Encapsulate the value of your attributes with quotes and avoid using upercase in tags.

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

That code isn't going to work, and it's not going to help you learn proper C++ if we fix it. It's better if you do something different. Raw arrays (especially multi-dimensional arrays) are difficult to pass correctly to and from functions. I think you'll be much better off starting with an object that represents an array but can be safely copied. Look up the documentation for std::vector.

In your code, you could use vector<vector<int> > or you could simulate a 2-D array with a 36-element vector<int>.

Swift 3 update :

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {
    if let urlResponse = navigationResponse.response as? HTTPURLResponse,
       let url = urlResponse.url,
       let allHeaderFields = urlResponse.allHeaderFields as? [String : String] {
       let cookies = HTTPCookie.cookies(withResponseHeaderFields: allHeaderFields, for: url)
       HTTPCookieStorage.shared.setCookies(cookies , for: urlResponse.url!, mainDocumentURL: nil)
       decisionHandler(.allow)
    }
}

You're probably looking for a Timer object: http://docs.python.org/2/library/threading.html#timer-objects

// The below C++ function checks for a palindrome and 
// returns true if it is a palindrome and returns false otherwise

bool checkPalindrome ( string s )
{
    // This calculates the length of the string

    int n = s.length();

    // the for loop iterates until the first half of the string
    // and checks first element with the last element,
    // second element with second last element and so on.
    // if those two characters are not same, hence we return false because
    // this string is not a palindrome 

    for ( int i = 0; i <= n/2; i++ ) 
    {
        if ( s[i] != s[n-1-i] )
            return false;
    }
    
    // if the above for loop executes completely , 
    // this implies that the string is palindrome, 
    // hence we return true and exit

    return true;
}

You shouldn't have to care that much. RFC 3339, according to itself, is a set of standards derived from ISO 8601. There's quite a few minute differences though, and they're all outlined in RFC 3339. I could go through them all here, but you'd probably do better just reading the document for yourself in the event you're worried:

http://tools.ietf.org/html/rfc3339

Check whether the USERNAME is correct, for me a new USERNAME got created with my proxy extension.

bool('True') and bool('False') always return True because strings 'True' and 'False' are not empty.

To quote a great man (and Python documentation):

5.1. Truth Value Testing

Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. The following values are considered false:

• …
• zero of any numeric type, for example, 0, 0L, 0.0, 0j.
• any empty sequence, for example, '', (), [].
• …

All other values are considered true — so objects of many types are always true.

The built-in bool function uses the standard truth testing procedure. That's why you're always getting True.

To convert a string to boolean you need to do something like this:

def str_to_bool(s):
    if s == 'True':
         return True
    elif s == 'False':
         return False
    else:
         raise ValueError # evil ValueError that doesn't tell you what the wrong value was

I just tested something like this in shell and seems to do it's job:

my_object_mapped = {attr.name: str(getattr(my_object, attr.name)) for attr in MyModel._meta.fields}

Note that if you want str() representation for foreign objects you should define it in their str method. From that you have dict of values for object. Then you can render some kind of template or whatever.

If you are on a Mac or BSD or something else without the --date option, you can use:

date -r `expr \`date +%s\` - 86400` '+%a %d/%m/%Y'

Update: or perhaps...

date -r $((`date +%s` - 86400)) '+%a %d/%m/%Y'

It is possible, as long as you know what instantiations you are going to need.

Add the following code at the end of stack.cpp and it'll work :

template class stack<int>;

All non-template methods of stack will be instantiated, and linking step will work fine.

<div>{{modal.title | slice: 0: 20}}</div>

Your elements need to have a position attribute. (e.g. absolute, relative, fixed) or z-index won't work.

You could try to force the browser to open a "Save As..." dialog by doing something like:

header('Content-type: text/csv');
header('Content-disposition: attachment;filename=MyVerySpecial.csv');
echo "cell 1, cell 2";

Which should work across most major browsers.

This one-liner tells where the shell script is, does not matter if you ran it or if you sourced it. Also, it resolves any symbolic links involved, if that is the case:

dir=$(dirname $(test -L "$BASH_SOURCE" && readlink -f "$BASH_SOURCE" || echo "$BASH_SOURCE"))

By the way, I suppose you are using /bin/bash.

You can use the Codecs module in the Python Standard Library, i.e.

import codecs

codecs.decode(hexstring, 'hex_codec')

You also need to be sure that returned bean is not empty (and can be serialized by Jackson). In my particular case I tried to return an instance of an object without getters and setters and without any jackson annotation and with fields equals to null. I got following message:

com.fasterxml.jackson.databind.JsonMappingException:
    No serializer found for class com.foo.bar.Baz and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) )

As it answers my original question, I have accepted doc_180's answer, but if someone runs into this problem again, I will answer the 2nd half of my question as well:

The NullPointerError I described had nothing to do with the List itself, but with its content!

The "MyClass" class didn't have a "no args" constructor, and neither had its superclass one. Once I added a simple "MyClass()" constructor to MyClass and its superclass, everything worked fine, including the List serialization and deserialization as suggested by doc_180.

Probably embed into your objects an ID "tag" and use it to distinguish between objects of class A and objects of class B.

This however shows a flaw in the design. Ideally those methods in B which A doesn't have, should be part of A but left empty, and B overwrites them. This does away with the class-specific code and is more in the spirit of OOP.

import scala.io.Source

object Demo {

  def main(args: Array[String]): Unit = {

    val ipfileStream = getClass.getResourceAsStream("/folder/a-words.txt")
    val readlines = Source.fromInputStream(ipfileStream).getLines
    readlines.foreach(readlines => println(readlines))

  }

}

In Java 11 we can use Collection.toArray(generator) method. The following code will create a new array of String:

Set<String> set = Set.of("one", "two", "three");
String[] array = set.toArray(String[]::new)

See: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/Collection.html#toArray(java.util.function.IntFunction)

You're looking for any class that implements the Queue interface, excluding PriorityQueue and PriorityBlockingQueue, which do not use a FIFO algorithm.

Probably a LinkedList using add (adds one to the end) and removeFirst (removes one from the front and returns it) is the easiest one to use.

For example, here's a program that uses a LinkedList to queue and retrieve the digits of PI:

import java.util.LinkedList;

class Test {
    public static void main(String args[]) {
        char arr[] = {3,1,4,1,5,9,2,6,5,3,5,8,9};
        LinkedList<Integer> fifo = new LinkedList<Integer>();

        for (int i = 0; i < arr.length; i++)
            fifo.add (new Integer (arr[i]));

        System.out.print (fifo.removeFirst() + ".");
        while (! fifo.isEmpty())
            System.out.print (fifo.removeFirst());
        System.out.println();
    }
} 

Alternatively, if you know you only want to treat it as a queue (without the extra features of a linked list), you can just use the Queue interface itself:

import java.util.LinkedList;
import java.util.Queue;

class Test {
    public static void main(String args[]) {
        char arr[] = {3,1,4,1,5,9,2,6,5,3,5,8,9};
        Queue<Integer> fifo = new LinkedList<Integer>();

        for (int i = 0; i < arr.length; i++)
            fifo.add (new Integer (arr[i]));

        System.out.print (fifo.remove() + ".");
        while (! fifo.isEmpty())
            System.out.print (fifo.remove());
        System.out.println();
    }
}

This has the advantage of allowing you to replace the underlying concrete class with any class that provides the Queue interface, without having to change the code too much.

The basic changes are to change the type of fifo to a Queue and to use remove() instead of removeFirst(), the latter being unavailable for the Queue interface.

Calling isEmpty() is still okay since that belongs to the Collection interface of which Queue is a derivative.

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.

main.c has a main wrapper like this:

#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
  // the true main() routine.
}

spi.c, serial.c and usb.c have main wrappers for their respective test code like this:

#ifdef TEST_USB
int main(int argc, char *argv[]) {
  // the  main() routine for testing the usb code.
}

config.h Which is included by all the c files has an entry like this:

// Uncomment below to test the serial
//#define TEST_SERIAL


// Uncomment below to test the spi code
//#define TEST_SPI

// Uncomment below to test the usb code
#define TEST_USB

No problem there. A simple git reset HEAD is what you're looking for because it leaves your files as modified just like a non-conflicting git stash pop.

The only problem is that your conflicting files will still have the conflict tags and git will no longer report them as conflicting with the "both_modified" flag which is useful.

To prevent this, just resolve the conflicts (edit and fix the conflicting files) before running git reset HEAD and you're good to go...

At the end of this process your stash will remain in the queue, so just do a git stash drop to clear it up.

This just happened to me and googled this question, so the solution has been tested.

I think that's as clean as it gets...

I've now found this function on WordPress Codec,

get queried

which is a wrapper for $wp_query->get_queried_object.

This post put me in the right direction, but it seems that it needs this update.

This is the Solution for jQuery 3.4

<script src="./js/util.js" data-m="myParam"></script>

$(document).ready(function () {
    var m = $('script[data-m][data-m!=null]').attr('data-m');
})

Another way with ES5 is to explicitely traverse the prototype chain using Object.getPrototypeOf(this)

const speaker = {
  speak: () => console.log('the speaker has spoken')
}

const announcingSpeaker = Object.create(speaker, {
  speak: {
    value: function() {
      console.log('Attention please!')
      Object.getPrototypeOf(this).speak()
    }
  }
})

announcingSpeaker.speak()

What's wrong with actually using ng-animate for ng-show as you mentioned?

<script src="lib/angulr.js"></script>
<script src="lib/angulr_animate.js"></script>
<script>
    var app=angular.module('ang_app', ['ngAnimate']);
    app.controller('ang_control01_main', function($scope) {

    });
</script>
<style>
    #myDiv {
        transition: .5s;
        background-color: lightblue;
        height: 100px;
    }
    #myDiv.ng-hide {
        height: 0;
    }
</style>
<body ng-app="ang_app" ng-controller="ang_control01_main">
    <input type="checkbox" ng-model="myCheck">
    <div id="myDiv" ng-show="myCheck"></div>
</body>

To directly save the file in HDFS, use the below command:

hive> insert overwrite  directory '/user/cloudera/Sample' row format delimited fields terminated by '\t' stored as textfile select * from table where id >100;

This will put the contents in the folder /user/cloudera/Sample in HDFS.

Also malloc and realloc are useful if you don't know ahead of time how many strings are being concatenated.

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

void example(const char *header, const char **words, size_t num_words)
{
    size_t message_len = strlen(header) + 1; /* + 1 for terminating NULL */
    char *message = (char*) malloc(message_len);
    strncat(message, header, message_len);

    for(int i = 0; i < num_words; ++i)
    {
       message_len += 1 + strlen(words[i]); /* 1 + for separator ';' */
       message = (char*) realloc(message, message_len);
       strncat(strncat(message, ";", message_len), words[i], message_len);
    }

    puts(message);

    free(message);
}

You don't need to read the next line, you are iterating through the lines. lines is a list (an array), and for line in lines is iterating over it. Every time you are finished with one you move onto the next line. If you want to skip to the next line just continue out of the current loop.

filne = "D:/testtube/testdkanimfilternode.txt"
f = open(filne, 'r+')

lines = f.readlines() # get all lines as a list (array)

# Iterate over each line, printing each line and then move to the next
for line in lines:
    print line

f.close()

select GROUP_CONCAT(stat SEPARATOR ' ') from (select concat('KILL ',id,';') as stat from information_schema.processlist) as stats;

Then copy and paste the result back into the terminal. Something like:

KILL 2871; KILL 2879; KILL 2874; KILL 2872; KILL 2866;

To add to the answers above: if you want to stop Dyno using admin panel, the current solution on free tier:

1. Open App
2. In Overview tab, in "Dyno formation" section click on "Configure Dynos"
3. In the needed row of "Free Dynos" section, click on the pencil icon on the right
4. Click on the blue on/off control, and then click on "Confirm"

Hope this helps.

If you have carriage return/line feeds within columns, str_getcsv will not work.

Try https://github.com/synappnz/php-csv

Use:

include "csv.php";
$csv = new csv(file_get_contents("filename.csv"));
$rows = $csv->rows();
foreach ($rows as $row)
{
  // do something with $row
}

Also, a good reason to use a controller vs. link function (since they both have access to the scope, element, and attrs) is because you can pass in any available service or dependency into a controller (and in any order), whereas you cannot do that with the link function. Notice the different signatures:

controller: function($scope, $exceptionHandler, $attr, $element, $parse, $myOtherService, someCrazyDependency) {...

vs.

link: function(scope, element, attrs) {... //no services allowed

Auto-incrementing the index in a loop:

myArr[(len(myArr)+1)]={"key":"val"}

Very simple 2 string answer to your question:

$array_1 = array(
  '0' => 'zero',
  '1' => 'one',
  '2' => 'two',
  '3' => 'three',
);

At first you insert anything to your third element with array_splice and then assign a value to this element:

array_splice($array_1, 3, 0 , true);
$array_1[3] = array('sample_key' => 'sample_value');

Method #1: Download from Here and insert it to your projects, or
Method #2: use below code before your bootstrap script source:

<script src="https://npmcdn.com/[email protected]/dist/js/tether.min.js"></script>

This error occurs on the server side when the client closed the socket connection before the response could be returned over the socket. In a web app scenario not all of these are dangerous, since they can be created manually. For example, by quitting the browser before the reponse was retrieved.

From dialog to activity that you want to refresh. If it not first activity!
Like this:mainActivity>>objectActivity>>dialog
In your dialog class:

  @Override
public void dismiss() {
    super.dismiss();
   getActivity().finish();
    Intent i = new Intent(getActivity(), objectActivity.class);  //your class
    startActivity(i);

}

What I did to get around this was to create a base class for all my activities where I store global data. In the first activity, I saved the context in a variable in my base class like so:

Base Class

public static Context myucontext; 

First Activity derived from the Base Class

mycontext = this

Then I use mycontext instead of getApplicationContext when creating dialogs.

AlertDialog alertDialog = new AlertDialog.Builder(mycontext).create();

In php, we have two option to concatenate table columns.

First Option using Query

In query, CONCAT keyword used to concatenate two columns

SELECT CONCAT(`SUBJECT`,'_', `YEAR`) AS subject_year FROM `table_name`;

Second Option using symbol ( . )

After fetch the data from database table, assign the values to variable, then using ( . ) Symbol and concatenate the values

$subject = $row['SUBJECT'];
$year = $row['YEAR'];
$subject_year = $subject . "_" . $year;

Instead of underscore( _ ) , we will use the spaces, comma, letters,numbers..etc

My answer might not be solution to your question but it will surely help others looking for similar issue like this one: javax.net.ssl.SSLHandshakeException: Chain validation failed

You just need to check your Android Device's Date and Time, it should be fix the issue. This resoled my problem.

As javascript is dynamically typed, rather than using the .length property as above you can simply treat the input value as a boolean:

var input = $.trim($("#spa").val());

if (input) {
    // Do Stuff
}

You can also extract the logic out into functions, then by assigning a class and using the each() method the code is more dynamic if, for example, in the future you wanted to add another input you wouldn't need to change any code.

So rather than hard coding the function call into the input markup, you can give the inputs a class, in this example it's test, and use:

$(".test").each(function () {
    $(this).keyup(function () {
        $("#submit").prop("disabled", CheckInputs());
    });
});

which would then call the following and return a boolean value to assign to the disabled property:

function CheckInputs() {
    var valid = false;
    $(".test").each(function () {
        if (valid) { return valid; }
        valid = !$.trim($(this).val());
    });
    return valid;
}

You can see a working example of everything I've mentioned in this JSFiddle.

Similar to other syntax above but for learning - can you sort by column names?

sort(colnames(test[1:ncol(test)] ))

UPDATED:
Matt provided a great link on how to add emulators for all Samsung devices.

OLD:
To get the official Samsung Galaxy Tab emulator do the following:

1. Open the Android SDK and AVD Manager
2. Click on Available packages
3. Expand the Third party Add-ons. There you will see Samsung Electronics add-ons.
4. Once the add-on is installed create a new emulator. Under Target you will see the new Samsung Tab settings, select that.

That's it!

I installed PHP on windows IIS using Windows Platform Installer (WP?). WP? creates a "PHP Manager" tool in "Internet Information Services (IIS) Manager" console. I am configuring PHP using this tool.

in http://php.net/manual/en/pdo.installation.php says:

PDO and all the major drivers ship with PHP as shared extensions, and simply need to be activated by editing the php.ini file: extension=php_pdo.dll

so i activated the extension using PHP Manager and now PDO works fine

PHP manager simple added the following two lines in my php.ini, you can add the lines by hand. Of course you must restart the web server.

[PHP_PDO_PGSQL]
extension=php_pdo_pgsql.dll

This thing worked for me pretty well:

<div id="{{ 'object-' + $index }}"></div>

Above answers are very elegant. I have written this function long back where i was also struggling to concatenate two dataframe with distinct columns.

Suppose you have dataframe sdf1 and sdf2

from pyspark.sql import functions as F
from pyspark.sql.types import *

def unequal_union_sdf(sdf1, sdf2):
    s_df1_schema = set((x.name, x.dataType) for x in sdf1.schema)
    s_df2_schema = set((x.name, x.dataType) for x in sdf2.schema)

    for i,j in s_df2_schema.difference(s_df1_schema):
        sdf1 = sdf1.withColumn(i,F.lit(None).cast(j))

    for i,j in s_df1_schema.difference(s_df2_schema):
        sdf2 = sdf2.withColumn(i,F.lit(None).cast(j))

    common_schema_colnames = sdf1.columns
    sdk = \
        sdf1.select(common_schema_colnames).union(sdf2.select(common_schema_colnames))
    return sdk 

sdf_concat = unequal_union_sdf(sdf1, sdf2) 

The only way I could do it in VS 2010 IDE was to highlight the block of code and hit ctrl-E and then C

Double d = 1000d;
System.out.println("Normal value :"+d);
System.out.println("Without decimal points :"+d.longValue());

You might just have to add a line feed "\n\r".

You need to replace the adbd binary in the boot.img/sbin/ folder to one that is su capable. You will also have to make some default.prop edits too.

Samsung seems to make this more difficult than other vendors. I have some adbd binaries you can try but it will require the knowledge of de-compiling and re-compiling the boot.img with the new binary. Also, if you have a locked bootloader... this is not gonna happen.

Also Chainfire has an app that will grant adbd root permission in the play store: https://play.google.com/store/apps/details?id=eu.chainfire.adbd&hl=en

Lastly, if you are trying to write a windows script with SU permissions you can do this buy using the following command style... However, you will at least need to grant (on the phone) SU permissions the frist time its ran...

adb shell "su -c ls" <-list working directory with su rights. adb shell "su -c echo anytext > /data/test.file"

These are just some examples. If you state specifically what you are trying to accomplish I may be able to give more specific advice

I had this issue, and solved by following:

Cause

There is a known bug with MySQL related to MyISAM, the UTF8 character set and indexes that you can check here.

Resolution

• Make sure MySQL is configured with the InnoDB storage engine.

• Change the storage engine used by default so that new tables will always be created appropriately:

  set GLOBAL storage_engine='InnoDb';

• For MySQL 5.6 and later, use the following:

  SET GLOBAL default_storage_engine = 'InnoDB';

• And finally make sure that you're following the instructions provided in Migrating to MySQL.

C itself doesn't support exceptions but you can simulate them to a degree with setjmp and longjmp calls.

static jmp_buf s_jumpBuffer;

void Example() { 
  if (setjmp(s_jumpBuffer)) {
    // The longjmp was executed and returned control here
    printf("Exception happened here\n");
  } else {
    // Normal code execution starts here
    Test();
  }
}

void Test() {
  // Rough equivalent of `throw`
  longjmp(s_jumpBuffer, 42);
}

This website has a nice tutorial on how to simulate exceptions with setjmp and longjmp

• http://www.di.unipi.it/~nids/docs/longjump_try_trow_catch.html

A solution that accept exceptions(passed by parameters):

Copy the below code and use it like this: $('myselector').maskOwnName(['of', 'on', 'a', 'as', 'at', 'for', 'in', 'to']);

(function($) {
    $.fn.maskOwnName = function(not_capitalize) {
            not_capitalize = !(not_capitalize instanceof Array)? []: not_capitalize;

        $(this).keypress(function(e){
            if(e.altKey || e.ctrlKey)
                return;

            var new_char = String.fromCharCode(e.which).toLowerCase();

            if(/[a-zà-ú\.\, ]/.test(new_char) || e.keyCode == 8){
                var start = this.selectionStart,
                    end = this.selectionEnd;

                if(e.keyCode == 8){
                    if(start == end)
                        start--;

                    new_char = '';
                }

                var new_value = [this.value.slice(0, start), new_char, this.value.slice(end)].join('');
                var maxlength = this.getAttribute('maxlength');
                var words = new_value.split(' ');
                start += new_char.length;
                end = start;

                if(maxlength === null || new_value.length <= maxlength)
                    e.preventDefault();
                else
                    return;

                for (var i = 0; i < words.length; i++){
                    words[i] = words[i].toLowerCase();

                    if(not_capitalize.indexOf(words[i]) == -1)
                        words[i] = words[i].substring(0,1).toUpperCase() + words[i].substring(1,words[i].length).toLowerCase();
                }

                this.value = words.join(' ');
                this.setSelectionRange(start, end);
            }
        });
    }

    $.fn.maskLowerName = function(pos) {
        $(this).css('text-transform', 'lowercase').bind('blur change', function(){
            this.value = this.value.toLowerCase();
        });
    }

    $.fn.maskUpperName = function(pos) {
        $(this).css('text-transform', 'uppercase').bind('blur change', function(){
            this.value = this.value.toUpperCase();
        });
    }
})(jQuery);

I use the following method in my JavaFX applications.

newWindowButton.setOnMouseClicked((event) -> {
    try {
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("NewWindow.fxml"));
        /* 
         * if "fx:controller" is not set in fxml
         * fxmlLoader.setController(NewWindowController);
         */
        Scene scene = new Scene(fxmlLoader.load(), 600, 400);
        Stage stage = new Stage();
        stage.setTitle("New Window");
        stage.setScene(scene);
        stage.show();
    } catch (IOException e) {
        Logger logger = Logger.getLogger(getClass().getName());
        logger.log(Level.SEVERE, "Failed to create new Window.", e);
    }
});

I didn't want to install a package just for that purpose so I ended up using this in my init.coffee:

spawn = require('child_process').spawn
atom.commands.add 'atom-text-editor', 'open-terminal', ->
  file = atom.workspace.getActiveTextEditor().getPath()
  dir = atom.project.getDirectoryForProjectPath(file).path
  spawn 'mate-terminal', ["--working-directory=#{dir}"], {
    detached: true
  }

With that, I could map ctrl-shift-t to the open-terminal command and it opens a mate-terminal.

Checking if array has all assoc-keys. With using stdClass & get_object_vars ^):

$assocArray = array('fruit1' => 'apple', 
                    'fruit2' => 'orange', 
                    'veg1' => 'tomato', 
                    'veg2' => 'carrot');

$assoc_object = (object) $assocArray;
$isAssoc = (count($assocArray) === count (get_object_vars($assoc_object)));  
var_dump($isAssoc); // true

Why? Function get_object_vars returns only accessible properties (see more about what is occuring during converting array to object here). Then, just logically: if count of basic array's elements equals count of object's accessible properties - all keys are assoc.

Few tests:

$assocArray = array('apple', 'orange', 'tomato', 'carrot');
$assoc_object = (object) $assocArray; 
$isAssoc = (count($assocArray) === count (get_object_vars($assoc_object)));
var_dump($isAssoc); // false 
//...

$assocArray = array( 0 => 'apple', 'orange', 'tomato', '4' => 'carrot');
$assoc_object = (object) $assocArray; 
$isAssoc = (count($assocArray) === count (get_object_vars($assoc_object)));
var_dump($isAssoc); // false 

//... 
$assocArray = array('fruit1' => 'apple', 
                    NULL => 'orange', 
                    'veg1' => 'tomato', 
                    'veg2' => 'carrot');

$assoc_object = (object) $assocArray;
$isAssoc = (count($assocArray) === count (get_object_vars($assoc_object)));  
var_dump($isAssoc); //false

Etc.

Your code seems fine except the result is an NSArray, not an NSDictionary, here is an example:

The first two lines just creates a data object with the JSON, the same as you would get reading it from the net.

NSString *jsonString = @"[{\"id\": \"1\", \"name\":\"Aaa\"}, {\"id\": \"2\", \"name\":\"Bbb\"}]";
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

NSError *e;
NSMutableArray *jsonList = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&e];
NSLog(@"jsonList: %@", jsonList);

NSLog contents (a list of dictionaries):

jsonList: (
           {
               id = 1;
               name = Aaa;
           },
           {
               id = 2;
               name = Bbb;
           }
           )

I know there is an accepted solution but I feel that the current solution results in a lot of boilerplate just so that you can test Models. My solution is essentially to take you model and place it inside of a function resulting in returning the new Model if the Model has not been registered but returning the existing Model if it has.

function getDemo () {
  // Create your Schema
  const DemoSchema = new mongoose.Schema({
    name: String,
    email: String
  }, {
    collection: 'demo'
  })
  // Check to see if the model has been registered with mongoose
  // if it exists return that model
  if (mongoose.models && mongoose.models.Demo) return mongoose.models.Demo
  // if no current model exists register and return new model
  return mongoose.model('Demo', DemoSchema)
}

export const Demo = getDemo()

Opening and closing connections all over the place is frustrating and does not compress well.

This way if I were to require the model two different places or more specifically in my tests I would not get errors and all the correct information is being returned.

• How can a developer use it?

I didn't find answer for this in the comments, here is how can be used:

1. Don't link your js.map file in your index.html file (no need for that)

2. Minifiacation tools (good ones) add a comment to your .min.js file:

   //# sourceMappingURL=yourFileName.min.js.map

which will connect your .map file.

When the min.js and js.map files are ready...

I believe fcntl() is a POSIX function. Where as ioctl() is a standard UNIX thing. Here is a list of POSIX io. ioctl() is a very kernel/driver/OS specific thing, but i am sure what you use works on most flavors of Unix. some other ioctl() stuff might only work on certain OS or even certain revs of it's kernel.

Some programs can't process output stream very well, using pipe to Out-Null may not block it.
And Start-Process needs the -ArgumentList switch to pass arguments, not so convenient.
There is also another approach.

$exitCode = [Diagnostics.Process]::Start(<process>,<arguments>).WaitForExit(<timeout>)

For IE, how about using a CSS expression:

<style type="text/css">
table td { 
  h: expression(this.style.border = (this == this.parentNode.lastChild ? 'none' : '1px solid #000' ) );
}
</style>

If the mysql dump was a .gz file, you need to gunzip to uncompress the file by typing $ gunzip mysqldump.sql.gz

This will uncompress the .gz file and will just store mysqldump.sql in the same location.

Type the following command to import sql data file:

$ mysql -u username -p -h localhost test-database < mysqldump.sql password: _

If you don’t need to pass arguments through then here’s a compact UAC prompting script that’s a single line long. This does a similar thing as the elevation script in the top voted answer but doesn’t pass arguments through since there’s no foolproof way to do that that handles every possible combination of poison characters.

net sess>nul 2>&1||(echo(CreateObject("Shell.Application"^).ShellExecute"%~0",,,"RunAs",1:CreateObject("Scripting.FileSystemObject"^).DeleteFile(wsh.ScriptFullName^)>"%temp%\%~nx0.vbs"&start wscript.exe "%temp%\%~nx0.vbs"&exit)

Place this just below the @echo off line in your batch script.

Explanation

The net sess>nul 2>&1 part is what checks for elevation. net sess is just shorthand for net session which is a command that returns an error code when the script doesn’t have elevated rights. I got this idea from this SO answer. Most of the answers here use net file instead though which works the same.

The error level is then checked with the || operator. If the check succeeds then it creates and executes a WScript which re-runs the original batch file but with elevated rights before deleting itself.

The WScript file is the best approach being fast and reliable, although it uses a temporary file. Here are some other variations and their dis/advantages.

PowerShell

net sess>nul 2>&1||(powershell saps '%0'-Verb RunAs&exit)

Pros:

• Very short.
• No temporary files.

Cons:

• Slow. PowerShell can be very slow to start up.
• Spews red text when the user declines the UAC prompt. The PowerShell command could be wrapped in a try..catch to prevent this though.

Mshta WSH script

net sess>nul 2>&1||(start mshta.exe vbscript:code(close(Execute("CreateObject(""Shell.Application"").ShellExecute""%~0"",,,""RunAs"",1"^)^)^)&exit)

Pros:

• Fast.
• No temporary files.

Cons:

• Not reliable. Some Windows 10 machines will block the script from running as Windows Defender intercepts it as a potential trojan.

DefaultTableModel dm = (DefaultTableModel)table.getModel();

What about creating an additional wrapper class?

package com.naveen.research.sql;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public abstract class PreparedStatementWrapper implements AutoCloseable {

    protected PreparedStatement stat;

    public PreparedStatementWrapper(Connection con, String query, Object ... params) throws SQLException {
        this.stat = con.prepareStatement(query);
        this.prepareStatement(params);
    }

    protected abstract void prepareStatement(Object ... params) throws SQLException;

    public ResultSet executeQuery() throws SQLException {
        return this.stat.executeQuery();
    }

    public int executeUpdate() throws SQLException {
        return this.stat.executeUpdate();
    }

    @Override
    public void close() {
        try {
            this.stat.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Then in the calling class you can implement prepareStatement method as:

try (Connection con = DriverManager.getConnection(JDBC_URL, prop);
    PreparedStatementWrapper stat = new PreparedStatementWrapper(con, query,
                new Object[] { 123L, "TEST" }) {
            @Override
            protected void prepareStatement(Object... params) throws SQLException {
                stat.setLong(1, Long.class.cast(params[0]));
                stat.setString(2, String.valueOf(params[1]));
            }
        };
        ResultSet rs = stat.executeQuery();) {
    while (rs.next())
        System.out.println(String.format("%s, %s", rs.getString(2), rs.getString(1)));
} catch (SQLException e) {
    e.printStackTrace();
}

<p>@Html.RadioButtonFor(x => x.type, "Item1")Item1</p>

To generalize the task of reading multiple header lines and to improve readability I'd use method extraction. Suppose you wanted to tokenize the first three lines of coordinates.txt to use as header information.

Example

coordinates.txt
---------------
Name,Longitude,Latitude,Elevation, Comments
String, Decimal Deg., Decimal Deg., Meters, String
Euler's Town,7.58857,47.559537,0, "Blah"
Faneuil Hall,-71.054773,42.360217,0
Yellowstone National Park,-110.588455,44.427963,0

Then method extraction allows you to specify what you want to do with the header information (in this example we simply tokenize the header lines based on the comma and return it as a list but there's room to do much more).

def __readheader(filehandle, numberheaderlines=1):
    """Reads the specified number of lines and returns the comma-delimited 
    strings on each line as a list"""
    for _ in range(numberheaderlines):
        yield map(str.strip, filehandle.readline().strip().split(','))

with open('coordinates.txt', 'r') as rh:
    # Single header line
    #print next(__readheader(rh))

    # Multiple header lines
    for headerline in __readheader(rh, numberheaderlines=2):
        print headerline  # Or do other stuff with headerline tokens

Output

['Name', 'Longitude', 'Latitude', 'Elevation', 'Comments']
['String', 'Decimal Deg.', 'Decimal Deg.', 'Meters', 'String']

If coordinates.txt contains another headerline, simply change numberheaderlines. Best of all, it's clear what __readheader(rh, numberheaderlines=2) is doing and we avoid the ambiguity of having to figure out or comment on why author of the the accepted answer uses next() in his code.

To set Conditional Formatting for an ENTIRE ROW based on a single cell you must ANCHOR that single cell's column address with a "$", otherwise Excel will only get the first column correct. Why?

Because Excel is setting your Conditional Format for the SECOND column of your row based on an OFFSET of columns. For the SECOND column, Excel has now moved one column to the RIGHT of your intended rule cell, examined THAT cell, and has correctly formatted column two based on a cell you never intended.

Simply anchor the COLUMN portion of your rule cell's address with "$", and you will be happy

For example: You want any row of your table to highlight red if the last cell of that row does not equal 1.

Select the entire table (but not the headings) "Home" > "Conditional Formatting" > "Manage Rules..." > "New Rule" > "Use a formula to determine which cells to format"

Enter: "=$T3<>1" (no quotes... "T" is the rule cell's column, "3" is its row) Set your formatting Click Apply.

Make sure Excel has not inserted quotes into any part of your formula... if it did, Backspace/Delete them out (no arrow keys please).

Conditional Formatting should be set for the entire table.

with(dfr[dfr$var3 < 155,], plot(var1, var2)) should do the trick.

Edit regarding multiple conditions:

with(dfr[(dfr$var3 < 155) & (dfr$var4 > 27),], plot(var1, var2))

If you are considering using multidimensional arrays, then there is one additional difference between std::array and std::vector. A multidimensional std::array will have the elements packed in memory in all dimensions, just as a c style array is. A multidimensional std::vector will not be packed in all dimensions.

Given the following declarations:

int cConc[3][5];
std::array<std::array<int, 5>, 3> aConc;
int **ptrConc;      // initialized to [3][5] via new and destructed via delete
std::vector<std::vector<int>> vConc;    // initialized to [3][5]

A pointer to the first element in the c-style array (cConc) or the std::array (aConc) can be iterated through the entire array by adding 1 to each preceding element. They are tightly packed.

A pointer to the first element in the vector array (vConc) or the pointer array (ptrConc) can only be iterated through the first 5 (in this case) elements, and then there are 12 bytes (on my system) of overhead for the next vector.

This means that a std::vector> array initialized as a [3][1000] array will be much smaller in memory than one initialized as a [1000][3] array, and both will be larger in memory than a std:array allocated either way.

This also means that you can't simply pass a multidimensional vector (or pointer) array to, say, openGL without accounting for the memory overhead, but you can naively pass a multidimensional std::array to openGL and have it work out.

Try this:

this.GetType().Name

Inside PhoneStateListener after seeing the call is finished better use:

Intent intent = new Intent(CallDispatcherActivity.this, CallDispatcherActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

Where CallDispatcherActivity is the activity where the user has launched a call (to a taxi service dispatcher, in my case). This just removes Android telephony app from the top, the user gets back instead of ugly code I saw here.

CSS has a clamp() function that holds the value between the upper and lower bound. The clamp() function enables the selection of the middle value in the range of values between the defined minimum and maximum values.

It simply takes three dimensions:

1. Minimum value.
2. List item
3. Preferred value Maximum allowed value.

try with the code below, and check the window resize, which will change the font size you see in the console. i set maximum value 150px and minimum value 100px.

$(window).resize(function(){_x000D_
    console.log($('#element').css('font-size'));_x000D_
});_x000D_
console.log($('#element').css('font-size'));

h1{_x000D_
    font-size: 10vw; /* Browsers that do not support "MIN () - MAX ()" and "Clamp ()" functions will take this value.*/_x000D_
    font-size: max(100px, min(10vw, 150px)); /* Browsers that do not support the "clamp ()" function will take this value. */_x000D_
    font-size: clamp(100px, 10vw, 150px);_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_

Updated answer for ES6+ is here.

arr = [1, 2, 3]; 

arr.forEach(function(i, idx, array){
   if (idx === array.length - 1){ 
       console.log("Last callback call at index " + idx + " with value " + i ); 
   }
});

would output:

Last callback call at index 2 with value 3

The way this works is testing arr.length against the current index of the array, passed to the callback function.

To get a NumPy array, you should use the values attribute:

In [1]: df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]}, index=['a', 'b', 'c']); df
   A  B
a  1  4
b  2  5
c  3  6

In [2]: df.index.values
Out[2]: array(['a', 'b', 'c'], dtype=object)

This accesses how the data is already stored, so there's no need for a conversion.
Note: This attribute is also available for many other pandas' objects.

In [3]: df['A'].values
Out[3]: Out[16]: array([1, 2, 3])

To get the index as a list, call tolist:

In [4]: df.index.tolist()
Out[4]: ['a', 'b', 'c']

And similarly, for columns.

If you want the result plus the number of rows returned do something like this. Using PHP.

$query = "SELECT * FROM Employee";
$result = mysql_query($query);
echo "There are ".mysql_num_rows($result)." Employee(s).";

I did this by creating a new XML file res/values/style.xml as follows:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="boldText">
        <item name="android:textStyle">bold|italic</item>
        <item name="android:textColor">#FFFFFF</item>
    </style>

    <style name="normalText">
        <item name="android:textStyle">normal</item>
        <item name="android:textColor">#C0C0C0</item>
    </style>

</resources>

I also have an entries in my "strings.xml" file like this:

<color name="highlightedTextViewColor">#000088</color>
<color name="normalTextViewColor">#000044</color>

Then, in my code I created a ClickListener to trap the tap event on that TextView: EDIT: As from API 23 'setTextAppearance' is deprecated

    myTextView.setOnClickListener(new View.OnClickListener() {
                public void onClick(View view){
                    //highlight the TextView
                    //myTextView.setTextAppearance(getApplicationContext(), R.style.boldText);
    if (Build.VERSION.SDK_INT < 23) {
       myTextView.setTextAppearance(getApplicationContext(), R.style.boldText);
    } else {
       myTextView.setTextAppearance(R.style.boldText);
    }
     myTextView.setBackgroundResource(R.color.highlightedTextViewColor);
                }
            });

To change it back, you would use this:

if (Build.VERSION.SDK_INT < 23) {
    myTextView.setTextAppearance(getApplicationContext(), R.style.normalText);
} else{
   myTextView.setTextAppearance(R.style.normalText);
}
myTextView.setBackgroundResource(R.color.normalTextViewColor);

I was setting up cors.support.credentials to true along with cors.allowed.origins as *, which won't work.

When cors.allowed.origins is * , then cors.support.credentials should be false (default value or shouldn't be set explicitly).

Well to make the decimal into a percent you can do this,

float percentage = (correct * 100.0f) / questionNum;

Invoking an empty time.Time struct literal will return Go's zero date. Thus, for the following print statement:

fmt.Println(time.Time{})

The output is:

0001-01-01 00:00:00 +0000 UTC

For the sake of completeness, the official documentation explicitly states:

The zero value of type Time is January 1, year 1, 00:00:00.000000000 UTC.

I'm using Entity Framework Core with my ASP.Net Core 3.x WebAPI. I wanted one of my end points just to execute a particular Stored Procedure, and this is the code I needed:

namespace MikesBank.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class ResetController : ControllerBase
    {
        private readonly MikesBankContext _context;

        public ResetController(MikesBankContext context)
        {
            _context = context;
        }

        [HttpGet]
        public async Task<ActionResult> Get()
        {
            try
            {
                using (DbConnection conn = _context.Database.GetDbConnection())
                {
                    if (conn.State != System.Data.ConnectionState.Open)
                        conn.Open();
                    var cmd = conn.CreateCommand();
                    cmd.CommandText = "Reset_Data";
                    await cmd.ExecuteNonQueryAsync();
                }
                return new OkObjectResult(1);
            }
            catch (Exception ex)
            {
                return new BadRequestObjectResult(ex.Message);
            }
        }
    }
}

Notice how I need to get my DbContext which has been injected, but I also need to Open() this connection.

After some research I finally got a VBA code to show the filter value in another cell:

Dim bRepresentAsRange As Boolean, bRangeBroken As Boolean
Dim sSelection As String
Dim tbl As Variant
bRepresentAsRange = False

With Worksheets("Forecast").PivotTables("ForecastbyDivision")
            ReDim tbl(.PageFields("Probability").PivotItems.Count)

                    tbl(n) = fld.Name
                    sSelection = sSelection & fld.Name & ","
                    n = n + 1
                    bRepresentAsRange = True
                Else

VB.net, Desktop application. If you need lapsed time in milliseconds:

Bootstrap.yml is used to fetch config from the server. It can be for a Spring cloud application or for others. Typically it looks like:

spring:
  application:
    name: "app-name"
  cloud:
    config:
      uri: ${config.server:http://some-server-where-config-resides}

When we start the application it tries to connect to the given server and read the configuration based on spring profile mentioned in run/debug configuration.

If the server is unreachable application might even be unable to proceed further. However, if configurations matching the profile are present locally the server configs get overridden.

Good approach:

Maintain a separate profile for local and run the app using different profiles.

Can someone help me with the exact syntax?

It's a three-step process, and it involves modifying the openssl.cnf file. You might be able to do it with only command line options, but I don't do it that way.

Find your openssl.cnf file. It is likely located in /usr/lib/ssl/openssl.cnf:

$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf

On my Debian system, /usr/lib/ssl/openssl.cnf is used by the built-in openssl program. On recent Debian systems it is located at /etc/ssl/openssl.cnf

You can determine which openssl.cnf is being used by adding a spurious XXX to the file and see if openssl chokes.

First, modify the req parameters. Add an alternate_names section to openssl.cnf with the names you want to use. There are no existing alternate_names sections, so it does not matter where you add it.

[ alternate_names ]

DNS.1        = example.com
DNS.2        = www.example.com
DNS.3        = mail.example.com
DNS.4        = ftp.example.com

Next, add the following to the existing [ v3_ca ] section. Search for the exact string [ v3_ca ]:

subjectAltName      = @alternate_names

You might change keyUsage to the following under [ v3_ca ]:

keyUsage = digitalSignature, keyEncipherment

digitalSignature and keyEncipherment are standard fare for a server certificate. Don't worry about nonRepudiation. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.

In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.

Second, modify the signing parameters. Find this line under the CA_default section:

# Extension copying option: use with caution.
# copy_extensions = copy

And change it to:

# Extension copying option: use with caution.
copy_extensions = copy

This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.

Third, generate your self-signed certificate:

$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...

Finally, examine the certificate:

$ openssl x509 -in certificate.pem -text -noout
Certificate:

Sun's JVM needs contiguous memory. So the maximal amount of available memory is dictated by memory fragmentation. Especially driver's dlls tend to fragment the memory, when loading into some predefined base address. So your hardware and its drivers determine how much memory you can get.

Two sources for this with statements from Sun engineers: forum blog

Maybe another JVM? Have you tried Harmony? I think they planned to allow non-continuous memory.

It was discussed before here.

In computer programming, a callback is a piece of executable code that is passed as an argument to other code, which is expected to call back (execute) the argument at some convenient time. The invocation may be immediate as in a synchronous callback or it might happen at later time, as in an asynchronous callback.

Hello Try this code below

public class RemoveCharacter {

    public static void main(String[] args){
        String str = "MXy nameX iXs farXazX";
        char x = 'X';
        System.out.println(removeChr(str,x));
    }

    public static String removeChr(String str, char x){
        StringBuilder strBuilder = new StringBuilder();
        char[] rmString = str.toCharArray();
        for(int i=0; i<rmString.length; i++){
            if(rmString[i] == x){

            } else {
                strBuilder.append(rmString[i]);
            }
        }
        return strBuilder.toString();
    }
}

Just use \t to space it.

Example:

System.out.println(monthlyInterest + "\t")

//as far as the two 0 in front of it just use a if else statement. ex: 
x = x+1;
if (x < 10){
    System.out.println("00" +x);
}
else if( x < 100){
    System.out.println("0" +x);
}
else{
    System.out.println(x);
}

There are other ways to do it, but this is the simplest.

Instead of merge, as others suggested, you can rebase one branch onto another:

git checkout BranchB
git rebase BranchA

This takes BranchB and rebases it onto BranchA, which effectively looks like BranchB was branched from BranchA, not master.

I had same issue but it turned out that it was because I created two different map API keys with same SHA-1 fingerprint with nearly similar package name com.bla.bla and the other com.bla.bla.something.

This might be helpful to somebody. here is the snippet from httpd.conf (Apache version 2.2 windows)

# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
<IfModule dir_module>
    DirectoryIndex index.html
    DirectoryIndex index.php
</IfModule>

now this will look for index.html file if not found it will look for index.php.

not nearly as concise as the link you provided: but the following chapter 14 - 24 may help :) hehe

ref: http://www.amazon.com/Coding-Standards-Rules-Guidelines-Practices/dp/0321113586/ref=sr_1_1?ie=UTF8&s=books&qid=1284443869&sr=8-1-catcorr

you seem to have not created an main method, which should probably look something like this (i am not sure)

  class RunThis
{
    public static void main(String[] args)
    {

    Calculate answer = new Calculate();
    answer.getNumber1();
    answer.getNumber2();
    answer.setNumber(answer.getNumber1() , answer.getNumber2());
    answer.getOper();
    answer.setOper(answer.getOper());
    answer.getAnswer();
    }
}

the point is you should have created a main method under some class and after compiling you should run the .class file containing main method. In this case the main method is under RunThis i.e RunThis.class.

I am new to java this may or may not be the right answer, correct me if i am wrong

echo "word1 word2 word3" | { read first rest ; echo $first ; }

This has the advantage that is not using external commands and leaves the $1, $2, etc. variables intact.

EDIT:

After your comments this actually makes perfect sense why you don't get a histogram of each different value. There are 1.4 million rows, and ten discrete buckets. So apparently each bucket is exactly 10% (to within what you can see in the plot).

A quick rerun of your data:

In [25]: df.hist(column='Trip_distance')

Prints out absolutely fine.

The df.hist function comes with an optional keyword argument bins=10 which buckets the data into discrete bins. With only 10 discrete bins and a more or less homogeneous distribution of hundreds of thousands of rows, you might not be able to see the difference in the ten different bins in your low resolution plot:

In [34]: df.hist(column='Trip_distance', bins=50)

This is how I achieved it in my code:

if($('.citiescheckbox:checked').length == $('.citiescheckbox').length){
    $('.citycontainer').hide();
}else{
    $('.citycontainer').show();
}

Your specific error is with line 11:

awk 'BEGIN{sum+=$2}'

This is a line where awk is invoked, and its BEGIN block is specified - but you are already within a awk script, so you do not need to specify awk. Also you want to run sum+=$2 on each line of input, so you do not want it within a BEGIN block. Hence the line should simply read:

sum+=$2

You also do not need the lines:

x=sum
read name

the first just creates a synonym to sum named x and I'm not sure what the second does, but neither are needed.

This would make your awk script:

#!/bin/awk

### This script currently prints the total number of rows processed.
### You must edit this script to print the average of the 2nd column
### instead of the number of rows.

# This block of code is executed for each line in the file
{
    sum+=$2
    # The script should NOT print out a value for each line
}
# The END block is processed after the last line is read
END {
    # NR is a variable equal to the number of rows in the file
    print "Average: " sum/ NR
    # Change this to print the Average instead of just the number of rows
}

Jonathan Leffler's answer gives the awk one liner which represents the same fixed code, with the addition of checking that there are at least 1 lines of input (this stops any divide by zero error). If

    $responseInfo = curl_getinfo($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
    $body = substr($response, $header_size);
    $result=array();
    $result['httpCode']=$httpCode;
    $result['body']=json_decode($body);
    $result['responseInfo']=$responseInfo;
    print_r($httpCode); 
     print_r($result['body']); exit;
    curl_close($ch);
    if($httpCode == 403)
    {
        print_r("Access denied");
        exit;
    }   
    else
     {
         //catch more errors 
     }

As a rule of thumb, the safest bet towards making your document be treated properly by all web servers, proxies, and client browsers, is probably the following:

1. Use the application/xml content type
2. Include a character encoding in the content type, probably UTF-8
3. Include a matching character encoding in the encoding attribute of the XML document itself.

In terms of the RFC 3023 spec, which some browsers fail to implement properly, the major difference in the content types is in how clients are supposed to treat the character encoding, as follows:

For application/xml, application/xml-dtd, application/xml-external-parsed-entity, or any one of the subtypes of application/xml such as application/atom+xml, application/rss+xml or application/rdf+xml, the character encoding is determined in this order:

1. the encoding given in the charset parameter of the Content-Type HTTP header
2. the encoding given in the encoding attribute of the XML declaration within the document,
3. utf-8.

For text/xml, text/xml-external-parsed-entity, or a subtype like text/foo+xml, the encoding attribute of the XML declaration within the document is ignored, and the character encoding is:

1. the encoding given in the charset parameter of the Content-Type HTTP header, or
2. us-ascii.

Most parsers don't implement the spec; they ignore the HTTP Context-Type and just use the encoding in the document. With so many ill-formed documents out there, that's unlikely to change any time soon.

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

There is a simpler way to solve this then what Slanec described. Hes solution works when you are using an English keyboard, if not you will have a hard time trying to "map" the key for special characters.

Instead of robot.keyPress and robot.keyRelease every single key you can use Toolkit to copy the String to the clipboard and then paste it.

    StringSelection s = new StringSelection("Path to the file");
    Toolkit.getDefaultToolkit().getSystemClipboard().setContents(s, null);
    Robot robot = new Robot();
    robot.keyPress(java.awt.event.KeyEvent.VK_ENTER);
    robot.keyRelease(java.awt.event.KeyEvent.VK_ENTER);
    robot.keyPress(java.awt.event.KeyEvent.VK_CONTROL);
    robot.keyPress(java.awt.event.KeyEvent.VK_V);
    robot.keyRelease(java.awt.event.KeyEvent.VK_CONTROL);
    Thread.sleep(3000);
    robot.keyPress(java.awt.event.KeyEvent.VK_ENTER);

On my side, this error came from the data type "INT' in the Null values column. The error is resolved by just changing the data a type to varchar.

You can't do that, because GetFiles only accepts a single search pattern. Instead, you can call GetFiles with no pattern, and filter the results in code:

string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };

FileInfo[] files =
    dinfo.GetFiles()
         .Where(f => extensions.Contains(f.Extension.ToLower()))
         .ToArray();

If you're working with .NET 4, you can use the EnumerateFiles method to avoid loading all FileInfo objects in memory at once:

string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };

FileInfo[] files =
    dinfo.EnumerateFiles()
         .Where(f => extensions.Contains(f.Extension.ToLower()))
         .ToArray();

if you are using c++11, here is a simple wrapper (see this gist):

#include <iostream>
#include <chrono>

class Timer
{
public:
    Timer() : beg_(clock_::now()) {}
    void reset() { beg_ = clock_::now(); }
    double elapsed() const { 
        return std::chrono::duration_cast<second_>
            (clock_::now() - beg_).count(); }

private:
    typedef std::chrono::high_resolution_clock clock_;
    typedef std::chrono::duration<double, std::ratio<1> > second_;
    std::chrono::time_point<clock_> beg_;
};

Or for c++03 on *nix:

#include <iostream>
#include <ctime>

class Timer
{
public:
    Timer() { clock_gettime(CLOCK_REALTIME, &beg_); }

    double elapsed() {
        clock_gettime(CLOCK_REALTIME, &end_);
        return end_.tv_sec - beg_.tv_sec +
            (end_.tv_nsec - beg_.tv_nsec) / 1000000000.;
    }

    void reset() { clock_gettime(CLOCK_REALTIME, &beg_); }

private:
    timespec beg_, end_;
};

Example of usage:

int main()
{
    Timer tmr;
    double t = tmr.elapsed();
    std::cout << t << std::endl;

    tmr.reset();
    t = tmr.elapsed();
    std::cout << t << std::endl;
    return 0;
}

Bit late on this thread. angular.equals does deep check, however does anyone know that why its behave differently if one of the member contain "$" in prefix ?

You can try this Demo with following input

var obj3 = {}
obj3.a=  "b";
obj3.b={};
obj3.b.$c =true;

var obj4 = {}
obj4.a=  "b";
obj4.b={};
obj4.b.$c =true;

angular.equals(obj3,obj4);

You're searching for gc_maxlifetime, see http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime for a description.

Your session will last 1440 seconds which is 24 minutes (default).

One of the biggest problems with delivering live events on Internet is 'scale', and TCP doesn’t scale well. For example when you are beaming a live football match -as opposed to an on demand movie playback- the number of people watching can easily be 1000 times more. In such a scenario using TCP is a death sentence for the CDNs (content delivery networks).

There are a couple of main reasons why TCP doesn't scale well:

1. One of the largest tradeoffs of TCP is the variability of throughput achievable between the sender and the receiver. When streaming video over the Internet the video packets must traverse multiple routers over the Internet, each of these routers is connected with different speed connections. The TCP algorithm starts with TCP window off small, then grows until packet loss is detected, the packet loss is considered a sign of congestion and TCP responds to it by drastically reducing the window size to avoid congestion. Thus in turn reducing the effective throughput immediately. Now imagine a network with TCP transmission using 6-7 router hops to the client (a very normal scenario), if any of the intermediate router looses any packet, the TCP for that link will reduce the transmission rate. In-fact The traffic flow between routers follow an hourglass kind of a shape; always gong up and down in-between one of the intermediate routers. Rendering the effective through put much lower compared to best-effort UDP.

2. As you may already know TCP is an acknowledgement-based protocol. Lets for example say a sender is 50ms away (i.e. latency btw two points). This would mean time it takes for a packet to be sent to a receiver and receiver to send an acknowledgement would be 100ms; thus maximum throughput possible as compared to UDP based transmission is already halved.

3. The TCP doesn’t support multicasting or the new emerging standard of multicasting AMT. Which means the CDNs don’t have the opportunity to reduce network traffic by replicating the packets -when many clients are watching the same content. That itself is a big enough reason for CDNs (like Akamai or Level3) to not go with TCP for live streams.

Its short and sweet

(?=.*jack)(?=.*james)

Test Cases:

[
  "xxx james xxx jack xxx",
  "jack xxx james ",
  "jack xxx jam ",
  "  jam and jack",
  "jack",
  "james",
]
.forEach(s => console.log(/(?=.*james)(?=.*jack)/.test(s)) )

This first choice might be a confusing one but it’s really very simple. PhoneGap is a product owned by Adobe which currently includes additional build services, and it may or may not eventually offer additional services and/or charge payments for use in the future. Cordova is owned and maintained by Apache, and will always be maintained as an open source project. Currently they both have a very similar API. I would recommend going with Cordova, unless you require the additional PhoneGap build services.

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

mkdirs() will create the specified directory path in its entirety where mkdir() will only create the bottom most directory, failing if it can't find the parent directory of the directory it is trying to create.

In other words mkdir() is like mkdir and mkdirs() is like mkdir -p.

For example, imagine we have an empty /tmp directory. The following code

new File("/tmp/one/two/three").mkdirs();

would create the following directories:

• /tmp/one
• /tmp/one/two
• /tmp/one/two/three

Where this code:

new File("/tmp/one/two/three").mkdir();

would not create any directories - as it wouldn't find /tmp/one/two - and would return false.

An ALTER TABLE statement adding the PRIMARY KEY column works correctly in my testing:

ALTER TABLE tbl ADD id INT PRIMARY KEY AUTO_INCREMENT;

On a temporary table created for testing purposes, the above statement created the AUTO_INCREMENT id column and inserted auto-increment values for each existing row in the table, starting with 1.

Jenkins Pipeline also provides the current build number as the property number of the currentBuild. It can be read as currentBuild.number.

For example:

// Scripted pipeline
def buildNumber = currentBuild.number

// Declarative pipeline
echo "Build number is ${currentBuild.number}"

Other properties of currentBuild are described in the Pipeline Syntax: Global Variables page that is included on each Pipeline job page. That page describes the global variables available in the Jenkins instance based on the current plugins.

You have a lot of unnecessary keyframes. Don't think of keyframes as individual frames, think of them as "steps" in your animation and the computer fills in the frames between the keyframes.

Here is a solution that cleans up a lot of code and makes the animation start from the center:

.gps_ring {
    border: 3px solid #999;
    -webkit-border-radius: 30px;
    height: 18px;
    width: 18px;
    position: absolute;
    left:20px;
    top:214px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    opacity: 0.0
}
@-webkit-keyframes pulsate {
    0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
    50% {opacity: 1.0;}
    100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}

You can see it in action here: http://jsfiddle.net/Fy8vD/

You simply cannot use WHERE when doing an INSERT statement:

 INSERT INTO Users( weight, desiredWeight ) VALUES ( 160, 145 ) WHERE id = 1;

should be:

 INSERT INTO Users( weight, desiredWeight ) VALUES ( 160, 145 );

The WHERE part only works in SELECT statements:

SELECT from Users WHERE id = 1;

or in UPDATE statements:

UPDATE Users set (weight = 160, desiredWeight = 145) WHERE id = 1;

Create/Open ~/.bashrc file $vim ~/.bashrc Add JAVA_HOME and PATH as refering to your JDK path

export JAVA_HOME=/usr/java/<your version of java>
export PATH=${PATH}:${JAVA_HOME}/bin

Save file

Now type java - version it should display what you set in .bashrc file. This will persisted over session as wel.

Example :

If you run the GWT compiler with the -localWorkers flag, the compiler will compile multiple permutations in parallel. This lets you use all the cores of a multi-core machine, for example -localWorkers 2 will tell the compiler to do compile two permutations in parallel. You won't get order of magnitudes differences (not everything in the compiler is parallelizable) but it is still a noticable speedup if you are compiling multiple permutations.

If you're willing to use the trunk version of GWT, you'll be able to use hosted mode for any browser (out of process hosted mode), which alleviates most of the current issues with hosted mode. That seems to be where the GWT is going - always develop with hosted mode, since compiles aren't likely to get magnitudes faster.

UPDATE some_table SET some_field = REPLACE(some_field, '&lt;', '<')

Python decorator is like a wrapper of a function or a class. It’s still too conceptual.

def function_decorator(func):
    def wrapped_func():
        # Do something before the function is executed
        func()
        # Do something after the function has been executed
    return wrapped_func

The above code is a definition of a decorator that decorates a function. function_decorator is the name of the decorator.

wrapped_func is the name of the inner function, which is actually only used in this decorator definition. func is the function that is being decorated. In the inner function wrapped_func, we can do whatever before and after the func is called. After the decorator is defined, we simply use it as follows.

@function_decorator
def func():
    pass

Then, whenever we call the function func, the behaviours we’ve defined in the decorator will also be executed.

EXAMPLE :

from functools import wraps

def mydecorator(f):
    @wraps(f)
    def wrapped(*args, **kwargs):
        print "Before decorated function"
        r = f(*args, **kwargs)
        print "After decorated function"
        return r
    return wrapped

@mydecorator
def myfunc(myarg):
    print "my function", myarg
    return "return value"

r = myfunc('asdf')
print r

Output :

    Before decorated function
    my function asdf
    After decorated function
    return value

I use GetRandomFileName:

The GetRandomFileName method returns a cryptographically strong, random string that can be used as either a folder name or a file name. Unlike GetTempFileName, GetRandomFileName does not create a file. When the security of your file system is paramount, this method should be used instead of GetTempFileName.

Example:

public static string GenerateFileName(string extension="")
{
    return string.Concat(Path.GetRandomFileName().Replace(".", ""),
        (!string.IsNullOrEmpty(extension)) ? (extension.StartsWith(".") ? extension : string.Concat(".", extension)) : "");
}

The difference is exactly what the name implies: a group by performs a grouping operation, and an order by sorts.

If you do SELECT * FROM Customers ORDER BY Name then you get the result list sorted by the customers name.

If you do SELECT IsActive, COUNT(*) FROM Customers GROUP BY IsActive you get a count of active and inactive customers. The group by aggregated the results based on the field you specified.

this worked for me for c#

if (enableEndDateCheckBox.Checked == true)
{
    endDateDateTimePicker.Enabled = true;
    endDateDateTimePicker.Format = DateTimePickerFormat.Short;                
}
else
{
    endDateDateTimePicker.Enabled = false;
    endDateDateTimePicker.Format = DateTimePickerFormat.Custom;
    endDateDateTimePicker.CustomFormat = " ";
}

nice one guys!

So if I get it right, on click of a button, you want to open up a modal that lists the values entered by the users followed by submitting it.

For this, you first change your input type="submit" to input type="button" and add data-toggle="modal" data-target="#confirm-submit" so that the modal gets triggered when you click on it:

<input type="button" name="btn" value="Submit" id="submitBtn" data-toggle="modal" data-target="#confirm-submit" class="btn btn-default" />

Next, the modal dialog:

<div class="modal fade" id="confirm-submit" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                Confirm Submit
            </div>
            <div class="modal-body">
                Are you sure you want to submit the following details?

                <!-- We display the details entered by the user here -->
                <table class="table">
                    <tr>
                        <th>Last Name</th>
                        <td id="lname"></td>
                    </tr>
                    <tr>
                        <th>First Name</th>
                        <td id="fname"></td>
                    </tr>
                </table>

            </div>

            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                <a href="#" id="submit" class="btn btn-success success">Submit</a>
            </div>
        </div>
    </div>
</div>

Lastly, a little bit of jQuery:

$('#submitBtn').click(function() {
     /* when the button in the form, display the entered values in the modal */
     $('#lname').text($('#lastname').val());
     $('#fname').text($('#firstname').val());
});

$('#submit').click(function(){
     /* when the submit button in the modal is clicked, submit the form */
    alert('submitting');
    $('#formfield').submit();
});

You haven't specified what the function validateForm() does, but based on this you should restrict your form from being submitted. Or you can run that function on the form's button #submitBtn click and then load the modal after the validations have been checked.

Another option is using System.IO.File.AppendText

This is equivalent to the StreamWriter overloads others have given.

Also File.AppendAllText may give a slightly easier interface without having to worry about opening and closing the stream. Though you may need to then worry about putting in your own linebreaks. :)

You need to use the await keyword when use async and your function return type should be generic Here is an example with return value:

public async Task<object> MethodName()
{
    return await Task.FromResult<object>(null);
}

Here is an example with no return value:

public async Task MethodName()
{
    await Task.CompletedTask;
}

Async: http://msdn.microsoft.com/en-us/library/hh156513.aspx Await: http://msdn.microsoft.com/en-us/library/hh156528.aspx

The functional way would imho be:

import static java.util.stream.Collectors.toList;
import java.util.Arrays;
import java.util.List;
import java.util.function.Predicate;

public class PredicateTestRun {

    public static void main(String[] args) {

        List<String> lines = Arrays.asList("a", "b", "c");
        System.out.println(lines); // [a, b, c]
        Predicate<? super String> predicate = value -> "b".equals(value);
        lines = lines.stream().filter(predicate.negate()).collect(toList());

        System.out.println(lines); // [a, c]
    }
}

In this solution the original list is not modified, but should contain your expected result in a new list that is accessible under the same variable as the old one

How about?

while BoolIter(N, default=True, falseIndex=N-1):
    print 'some thing'

or in a more ugly way:

for _ in BoolIter(N):
    print 'doing somthing'

or if you want to catch the last time through:

for lastIteration in BoolIter(N, default=False, trueIndex=N-1):
    if not lastIteration:
        print 'still going'
    else:
        print 'last time'

where:

class BoolIter(object):

    def __init__(self, n, default=False, falseIndex=None, trueIndex=None, falseIndexes=[], trueIndexes=[], emitObject=False):
        self.n = n
        self.i = None
        self._default = default
        self._falseIndexes=set(falseIndexes)
        self._trueIndexes=set(trueIndexes)
        if falseIndex is not None:
            self._falseIndexes.add(falseIndex)
        if trueIndex is not None:
            self._trueIndexes.add(trueIndex)
        self._emitObject = emitObject


    def __iter__(self):
        return self

    def next(self):
        if self.i is None:
            self.i = 0
        else:
            self.i += 1
        if self.i == self.n:
            raise StopIteration
        if self._emitObject:
            return self
        else:
            return self.__nonzero__()

    def __nonzero__(self):
        i = self.i
        if i in self._trueIndexes:
            return True
        if i in self._falseIndexes:
            return False
        return self._default

    def __bool__(self):
        return self.__nonzero__()

It has been three years since this question was asked, but I am just now coming across it. Since this answer is so far down the stack, please allow me to repeat it:

Q: I am interested if there are any limits to what types of values can be set using const in JavaScript—in particular functions. Is this valid? Granted it does work, but is it considered bad practice for any reason?

I was motivated to do some research after observing one prolific JavaScript coder who always uses const statement for functions, even when there is no apparent reason/benefit.

In answer to "is it considered bad practice for any reason?" let me say, IMO, yes it is, or at least, there are advantages to using function statement.

It seems to me that this is largely a matter of preference and style. There are some good arguments presented above, but none so clear as is done in this article:

Constant confusion: why I still use JavaScript function statements by medium.freecodecamp.org/Bill Sourour, JavaScript guru, consultant, and teacher.

I urge everyone to read that article, even if you have already made a decision.

Here's are the main points:

Function statements have two clear advantages over [const] function expressions:

Advantage #1: Clarity of intent

When scanning through thousands of lines of code a day, it’s useful to be able to figure out the programmer’s intent as quickly and easily as possible.

Advantage #2: Order of declaration == order of execution

Ideally, I want to declare my code more or less in the order that I expect it will get executed.

This is the showstopper for me: any value declared using the const keyword is inaccessible until execution reaches it.

What I’ve just described above forces us to write code that looks upside down. We have to start with the lowest level function and work our way up.

My brain doesn’t work that way. I want the context before the details.

Most code is written by humans. So it makes sense that most people’s order of understanding roughly follows most code’s order of execution.

I have tried many tips but the only one that works is this one. Update the Maven configuration. Right-click on pom.xml, Run as -> Maven build (the 2nd one). Enter "clean package" in the Goals fields. Check the Skip Tests box. Then Run, it will properly download all the jars and the problem is fixed.

tl;dr

Just replace:

• compile with implementation (if you don't need transitivity) or api (if you need transitivity)
• testCompile with testImplementation
• debugCompile with debugImplementation
• androidTestCompile with androidTestImplementation
• compileOnly is still valid. It was added in 3.0 to replace provided and not compile. (provided introduced when Gradle didn't have a configuration name for that use-case and named it after Maven's provided scope.)

It is one of the breaking changes coming with Android Gradle plugin 3.0 that Google announced at IO17.

The compile configuration is now deprecated and should be replaced by implementation or api

From the Gradle documentation:

dependencies {
    api 'commons-httpclient:commons-httpclient:3.1'
    implementation 'org.apache.commons:commons-lang3:3.5'
}

Dependencies appearing in the api configurations will be transitively exposed to consumers of the library, and as such will appear on the compile classpath of consumers.

Dependencies found in the implementation configuration will, on the other hand, not be exposed to consumers, and therefore not leak into the consumers' compile classpath. This comes with several benefits:

• dependencies do not leak into the compile classpath of consumers anymore, so you will never accidentally depend on a transitive dependency
• faster compilation thanks to reduced classpath size
• less recompilations when implementation dependencies change: consumers would not need to be recompiled
• cleaner publishing: when used in conjunction with the new maven-publish plugin, Java libraries produce POM files that distinguish exactly between what is required to compile against the library and what is required to use the library at runtime (in other words, don't mix what is needed to compile the library itself and what is needed to compile against the library).

The compile configuration still exists, but should not be used as it will not offer the guarantees that the api and implementation configurations provide.

Note: if you are only using a library in your app module -the common case- you won't notice any difference.
you will only see the difference if you have a complex project with modules depending on each other, or you are creating a library.

With JavaScript you can create a link 'on the fly' using something like:

var mail = document.createElement("a");
mail.href = "mailto:[email protected]";
mail.click();

This is redirected by the browser to some mail client installed on the machine without losing the content of the current window ... and you would not need any API like 'jQuery'.

mongod wasn't working to start the daemon for me but after I ran the following, it started working:

'mongod --fork --logpath /var/log/mongodb.log'

(from here: https://docs.mongodb.com/manual/tutorial/manage-mongodb-processes/)

That is interesting subject. You can play around with two lifecycle hooks to figure out how it works: ngOnChanges and ngOnInit.

Basically when you set default value to Input that's mean it will be used only in case there will be no value coming on that component. And the interesting part it will be changed before component will be initialized.

Let's say we have such components with two lifecycle hooks and one property coming from input.

@Component({
  selector: 'cmp',
})
export class Login implements OnChanges, OnInit {
  @Input() property: string = 'default';

  ngOnChanges(changes) {
    console.log('Changed', changes.property.currentValue, changes.property.previousValue);
  }

  ngOnInit() {
    console.log('Init', this.property);
  }

}

Situation 1

Component included in html without defined property value

As result we will see in console: Init default

That's mean onChange was not triggered. Init was triggered and property value is default as expected.

Situation 2

Component included in html with setted property <cmp [property]="'new value'"></cmp>

As result we will see in console:

Changed new value Object {}

Init new value

And this one is interesting. Firstly was triggered onChange hook, which setted property to new value, and previous value was empty object! And only after that onInit hook was triggered with new value of property.

like say a class .c1 has height:40px; how do I get rid of this height property?

Sadly, you can't. CSS doesn't have a "default" placeholder.

In that case, you would reset the property using

 height: auto;

as @Ben correctly points out, in some cases, inherit is the correct way to go, for example when resetting the text colour of an a element (that property is inherited from the parent element):

a { color: inherit }

It's extremely unlikely that an if/else or a switch is going to be the source of your performance woes. If you're having performance problems, you should do a performance profiling analysis first to determine where the slow spots are. Premature optimization is the root of all evil!

Nevertheless, it's possible to talk about the relative performance of switch vs. if/else with the Java compiler optimizations. First note that in Java, switch statements operate on a very limited domain -- integers. In general, you can view a switch statement as follows:

switch (<condition>) {
   case c_0: ...
   case c_1: ...
   ...
   case c_n: ...
   default: ...
}

where c_0, c_1, ..., and c_N are integral numbers that are targets of the switch statement, and <condition> must resolve to an integer expression.

• If this set is "dense" -- that is, (max(c_i) + 1 - min(c_i)) / n > α, where 0 < k < α < 1, where k is larger than some empirical value, a jump table can be generated, which is highly efficient.

• If this set is not very dense, but n >= β, a binary search tree can find the target in O(2 * log(n)) which is still efficient too.

For all other cases, a switch statement is exactly as efficient as the equivalent series of if/else statements. The precise values of α and β depend on a number of factors and are determined by the compiler's code-optimization module.

Finally, of course, if the domain of <condition> is not the integers, a switch statement is completely useless.

This would work well especially for those using Bootstrap, tested in latest browser versions:

  -webkit-appearance: none;_x000D_
  -moz-appearance: none;_x000D_

Actually I use _ method names when I need to differ between parent and child class names. I've read some codes that used this way of creating parent-child classes. As an example I can provide this code:

class ThreadableMixin:
   def start_worker(self):
       threading.Thread(target=self.worker).start()

   def worker(self):
      try:
        self._worker()
    except tornado.web.HTTPError, e:
        self.set_status(e.status_code)
    except:
        logging.error("_worker problem", exc_info=True)
        self.set_status(500)
    tornado.ioloop.IOLoop.instance().add_callback(self.async_callback(self.results))

...

and the child that have a _worker method

class Handler(tornado.web.RequestHandler, ThreadableMixin):
   def _worker(self):
      self.res = self.render_string("template.html",
        title = _("Title"),
        data = self.application.db.query("select ... where object_id=%s", self.object_id)
    )

...

You may want to use:

SELECT Name, 'Unpaid' AS Status FROM table;

The SELECT clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:

SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ] 
<select_list> 

Where the expression can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.

Base href example

Say a typical page with links:

<a href=home>home</a> <a href=faq>faq</a> <a href=etc>etc</a>

.and links to a diff folder:

..<a href=../p2/home>Portal2home</a> <a href=../p2/faq>p2faq</a> <a href=../p2/etc>p2etc</a>..

With base href, we can avoid repeating the base folder:

<base href=../p2/>
<a href=home>Portal2-Home</a> <a href=faq>P2FAQ</a> <a href=contact>P2Contact</a>

So that's a win.. yet pages too-often contain urls to diff bases And the current web supports only one base href per page, so the win is quickly lost as bases that aint base∙hrefed repeats, eg:

<a href=../p1/home>home</a> <a href=../p1/faq>faq</a> <a href=../p1/etc>etc</a>
<!--.. <../p1/> basepath is repeated -->

<base href=../p2>
<a href=home>Portal2-Home</a> <a href=faq>P2FAQ</a> <a href=contact>P2Contact</a>

(Base target might be useful.) Base href is useless as:

• page is equally WET since:
  • default base [–parent folder] ⇌ perfect (unless unnecessary/rare exceptions 𝒞1 & 𝒞2).
  • current web ⇌ multiple base hrefs unsupported.

Believe me or not... I tried out almost each answer I had found here on stackoverflow. Nothing would help, until I just restarted the machine. My Android Studio works on Ubuntu 16.04 LTS.

For loading weights, you need to have a model first. It must be:

existingModel.save_weights('weightsfile.h5')
existingModel.load_weights('weightsfile.h5')     

If you want to save and load the entire model (this includes the model's configuration, it's weights and the optimizer states for further training):

model.save_model('filename')
model = load_model('filename')

If you're using Python 3.4, there is the brand new higher-level pathlib module which allows you to conveniently call pathlib.Path.cwd() to get a Path object representing your current working directory, along with many other new features.

More info on this new API can be found here.

@Patrick I would improve your solution a bit

@Override
public Object deserialize(JsonParser jp, DeserializationContext ctxt)
        throws IOException, JsonProcessingException {        
    ObjectNode objectNode = jp.readValueAsTree();
    JsonNode wrapped = objectNode.get(wrapperKey);
    JsonParser parser = node.traverse();
    parser.setCodec(jp.getCodec());
    Vendor mapped = parser.readValueAs(Vendor.class);
    return mapped;
}

It works faster :)

Through the Javascript SDK (v2.12 - April, 2017) you can get the details of the picture request this way:

FB.api("/" + uid + "/picture?redirect=0", function (response) {
  console.log(response);

  // prints the following:
  //data: {
  //  height: 50
  //  is_silhouette: false
  //  url: "https://lookaside.facebook.com/platform/profilepic/?asid=…&height=50&width=50&ext=…&hash…"
  //  width: 50
  //}

  if (response && !response.error) {
    // change the src attribute of img elements
    [...document.getElementsByClassName('fb-user-img')].forEach(
      i => i.src = response.data.url
    );

    // OR redirect to the URL above
    location.assign(response.data.url);
  }
});

For getting the JSON response the parameter redirect with 0 (zero) as value is important since the request redirects to the image by default. You may still add other parameters in the same URL. Examples:

• "/" + uid + "/picture?redirect=0&width=100&height=100": a 100x100 image will be returned;
• "/" + uid + "/picture?redirect=0&type=large": a 200x200 image is returned. Other possible type values include: small, normal, album, and square.

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

You have several problems.

First, you have the example that you cited.

You also have a similar problem if rows are inserted, but in this case the user get duplicate data (arguably easier to manage than missing data, but still an issue).

If you are not snapshotting the original data set, then this is just a fact of life.

You can have the user make an explicit snapshot:

POST /createquery
filter.firstName=Bob&filter.lastName=Eubanks

Which results:

HTTP/1.1 301 Here's your query
Location: http://www.example.org/query/12345

Then you can page that all day long, since it's now static. This can be reasonably light weight, since you can just capture the actual document keys rather than the entire rows.

If the use case is simply that your users want (and need) all of the data, then you can simply give it to them:

GET /query/12345?all=true

and just send the whole kit.

If you want to manually clean it up, for me with my version of jenkins (didn't appear to need an extra plugin installed, but who knows), there is a "workspace" link on the left column, click on your project, then on "workspace", then a "Wipe out current workspace" link appears beneath it on the left hand side column.

Just use the command go run *.go to execute all the go files in your package!

I'd stay well away from using MAC addresses. On some hardware, the MAC address can change when you reboot. We learned quite early during our research not to rely on it.

Take a look at the article Developing for Software Protection and Licensing which has some pointers on how to design & implement apps to reduce piracy.

Obligatory disclaimer & plug: the company I co-founded produces the OffByZero Cobalt licensing solution. So it probably won't surprise you to hear that I recommend outsourcing your licensing, & focusing on your core competencies.

The __pycache__ folder and *.pyc files are totally unnecessary to the developer. To hide these files from the explorer view, we need to edit the settings.json for VSCode. Add the folder and the files as shown below:

"files.exclude": {
  ...
  ...
  "**/*.pyc": {"when": "$(basename).py"}, 
  "**/__pycache__": true,
  ...
  ...
}

I think what you want is MySQL's information_schema view(s): http://dev.mysql.com/doc/refman/5.0/en/tables-table.html

Usually when a method accepts a file, there's another method nearby that accepts a stream. If this isn't the case, the API is badly coded. Otherwise, you can use temporary files, where permission is usually granted in many cases. If it's applet, you can request write permission.

An example:

try {
    // Create temp file.
    File temp = File.createTempFile("pattern", ".suffix");

    // Delete temp file when program exits.
    temp.deleteOnExit();

    // Write to temp file
    BufferedWriter out = new BufferedWriter(new FileWriter(temp));
    out.write("aString");
    out.close();
} catch (IOException e) {
}

Seems like only real solutions today revolve around scaling out or sharding. All modern databases (NoSQLs as well as NewSQLs) support horizontal scaling right out of the box, at the database layer, without the need for the application to have sharding code or something.

Unfortunately enough, for the trusted good-old MySQL, sharding is not provided "out of the box". ScaleBase (disclaimer: I work there) is a maker of a complete scale-out solution an "automatic sharding machine" if you like. ScaleBae analyzes your data and SQL stream, splits the data across DB nodes, and aggregates in runtime – so you won’t have to! And it's free download.

Don't get me wrong, NoSQLs are great, they're new, new is more choice and choice is always good!! But choosing NoSQL comes with a price, make sure you can pay it...

You can see here some more data about MySQL, NoSQL...: http://www.scalebase.com/extreme-scalability-with-mongodb-and-mysql-part-1-auto-sharding

Hope that helped.

For 2005 up, you can use

SELECT
        [name]
       ,create_date
       ,modify_date
FROM
        sys.tables

I think for 2000, you need to have enabled auditing.

By default, tnsnames.ora is located in the $ORACLE_HOME/network/admin directory on UNIX operating systems and in the ORACLE_HOME\network\admin directory on Windows operating systems. tnsnames.ora can also be stored the following locations:

The directory specified by the TNS_ADMIN environment variable (or registry value)

On UNIX operating systems, the global configuration directory. For example, on the Solaris Operating System, this directory is /var/opt/oracle

If you have multiple ORACLE_HOMES, be aware of which one you are using, as the location of the tnsnames.ora file can vary from one ORACLE_HOME to the next.

For the person who mentioned the TWO_TASK environment variable, that is used to set a default database service name to connect to (which could be a database on another server). The service name you set TWO_TASK to is then looked up in the tnsnames.ora file when you connect.

First off, it's helpful to create a database named the same as your current use, to prevent the error when you just want to use the default database and create new tables without declaring the name of a db explicitly.

Replace "skynotify" with your username:

psql -d postgres -c "CREATE DATABASE skynotify ENCODING 'UTF-8';"

-d explicitly declares which database to use as the default for SQL statements that don't explicitly include a db name during this interactive session.

BASICS FOR GETTING A CLEAR PICTURE OF WHAT YOUR PostgresQL SERVER has in it.

You must connect to an existing database to use psql interactively. Fortunately, you can ask psql for a list of databases:

psql -l

.

                                          List of databases
               Name               | Owner  | Encoding |   Collate   |    Ctype    | Access privileges

                                  |           |          |             |             | skynotify=CTc/skynotify
 template1                        | skynotify | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/skynotify          +
                                  |           |          |             |             | skynotify=CTc/skynotify
(6 rows)

This does NOT start the interactive console, it just outputs a text based table to the terminal.

As another answers says, postgres is always created, so you should use it as your failsafe database when you just want to get the console started to work on other databases. If it isn't there, then list the databases and then use any one of them.

In a similar fashion, select tables from a database:

psql -d postgres -c "\dt;"

My "postgres" database has no tables, but any database that does will output a text based table to the terminal (standard out).

And for completeness, we can select all rows from a table too:

psql -d ruby-getting-started_development -c "SELECT * FROM widgets;"

.

 id | name | description | stock | created_at | updated_at 
----+------+-------------+-------+------------+------------
(0 rows)

Even if there are zero rows returned, you'll get the field names.

If your tables have more than a dozen rows, or you're not sure, it'll be more useful to start with a count of rows to understand how much data is in your database:

 psql -d ruby-getting-started_development -c "SELECT count(*) FROM widgets;"

.

 count 
-------
     0
(1 row)

And don't that that "1 row" confuse you, it just represents how many rows are returned by the query, but the 1 row contains the count you want, which is 0 in this example.

NOTE: a db created without an owner defined will be owned by the current user.

Uso algo simples assim ;)

You can update the existing package-lock.json file instead of creating a new one. Just change the version number to a different one.

{ "name": "theme","version": "1.0.1", "description": "theme description"}

This answer is outdated

If these are folders you want to ignore in a certain workspace, you can go to:

AppMenu > Preferences > Workspace Settings

Otherwise, if you want these folders to be ignored in all your workspaces, go to:

AppMenu > Preferences > User Settings

and add the following to your configuration:

//-------- Search configuration --------

// The folders to exclude when doing a full text search in the workspace.
"search.excludeFolders": [
    ".git",
    "node_modules",
    "bower_components",
    "path/to/other/folder/to/exclude"
],

The difference between workspace and user settings is explained in the customization docs

you can do this:

file= open(r'D:\\zzzz\\names2.txt')
file_split=set(file.read().split())
print(len(file_split))

Have you tried (from a command line)

java -jar jbpm-installer-3.2.7.jar

or double clicking it with the mouse ?

Found this and this by googling.

Hope it helps

There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.

One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.

You need to include inttypes.h if you want all those nifty new format specifiers for the intN_t types and their brethren, and that is the correct (ie, portable) way to do it, provided your compiler complies with C99. You shouldn't use the standard ones like %d or %u in case the sizes are different to what you think.

It includes stdint.h and extends it with quite a few other things, such as the macros that can be used for the printf/scanf family of calls. This is covered in section 7.8 of the ISO C99 standard.

For example, the following program:

#include <stdio.h>
#include <inttypes.h>
int main (void) {
    uint32_t a=1234;
    uint16_t b=5678;
    printf("%" PRIu32 "\n",a);
    printf("%" PRIu16 "\n",b);
    return 0;
}

outputs:

1234
5678

• Use float: right to.. float the second column to the.. right.
• Use overflow: hidden to clear the floats so that the background color I just put in will be visible.

Live Demo

#wrapper{
    background:#000;
    overflow: hidden
}
#c1 {
   float:left;
   background:red;
}
#c2 {
    background:green;
    float: right
