Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

Don't know if this helps anyone but I was struggling with this problem for awhile, none of the answers online helped me. For me the problem was I had different heights and widths set on the image in storyboard. I tried every solution on stack and it turns out it was something as simple as that. Once I set them both to 200 my circle profile image was perfect. This was code then in my VC.

profileImage2.layer.cornerRadius = profileImage2.frame.size.width/2
    profileImage2.clipsToBounds = true

This is really just a syntax switch. OK, so we have this method call:

[NSPredicate predicateWithFormat:@"name contains[c] %@", searchText];

In Swift, constructors skip the "blahWith…" part and just use the class name as a function and then go straight to the arguments, so [NSPredicate predicateWithFormat: …] would become NSPredicate(format: …). (For another example, [NSArray arrayWithObject: …] would become NSArray(object: …). This is a regular pattern in Swift.)

So now we just need to pass the arguments to the constructor. In Objective-C, NSString literals look like @"", but in Swift we just use quotation marks for strings. So that gives us:

let resultPredicate = NSPredicate(format: "name contains[c] %@", searchText)

And in fact that is exactly what we need here.

(Incidentally, you'll notice some of the other answers instead use a format string like "name contains[c] \(searchText)". That is not correct. That uses string interpolation, which is different from predicate formatting and will generally not work for this.)

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

I believe that phrase should have been worded as follows:

bcrypt has salts built into the generated hashes to prevent rainbow table attacks.

The bcrypt utility itself does not appear to maintain a list of salts. Rather, salts are generated randomly and appended to the output of the function so that they are remembered later on (according to the Java implementation of bcrypt). Put another way, the "hash" generated by bcrypt is not just the hash. Rather, it is the hash and the salt concatenated.

From the Project Explorer, expand the project you want to hook up to a remote site (or just right click and create a new Web project that's empty if you just want to explore a remote site from there). There's a "Connections" node, right click it and select "Add New connection...". A dialog will appear, at bottom you can select the destination as Remote and then click the "New..." button. There you can set up an FTP/FTPS/SFTP connection.

That's how you set up a connection that's tied to a project, typically for upload/download/sync between it and a project.

You can also do Window > Show View > Remote. From that view, you can click the globe icon in the upper right to add connections and in this view you can just browse your remote connections.

Textmate is state of the Art editor, but if someone is thinking about developing on several platforms without awkward memory eaters monsters like jedit, eclipse, netbeans etc take a look at geany (geany.org). It is free. The only problem the editor has not esthetic look and feel on Mac OS X :)

grep -n 'loom' ~/projects/**/trunk/src/**/*.@(h|cpp) | grep -v 'gloom'

For me, align="center" was enough to center FOO vertically:

<v-row align="center">
  <v-col>FOO</v-col>
</row>

Or you can do that with ES6 template literal:

<a :href="`/job/${r.id}`"

If you follow your link, it tells you that the error results from the $injector not being able to resolve your dependencies. This is a common issue with angular when the javascript gets minified/uglified/whatever you're doing to it for production.

The issue is when you have e.g. a controller;

angular.module("MyApp").controller("MyCtrl", function($scope, $q) {
  // your code
})

The minification changes $scope and $q into random variables that doesn't tell angular what to inject. The solution is to declare your dependencies like this:

angular.module("MyApp")
  .controller("MyCtrl", ["$scope", "$q", function($scope, $q) {
  // your code
}])

That should fix your problem.

Just to re-iterate, everything I've said is at the link the error message provides to you.

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

The post Reset Demystified in the blog Pro Git gives a very no-brainer explanation on git reset and git checkout.

After all the helpful discussion at the top of that post, the author reduces the rules to the following simple three steps:

That is basically it. The reset command overwrites these three trees in a specific order, stopping when you tell it to.

1. Move whatever branch HEAD points to (stop if --soft)
2. THEN, make the Index look like that (stop here unless --hard)
3. THEN, make the Working Directory look like that

There are also --merge and --keep options, but I would rather keep things simpler for now - that will be for another article.

I found this on another site not sure if it works or not.

Application.Wait Now + 1/(24*60*60.0*2)

the numerical value 1 = 1 day

1/24 is one hour

1/(24*60) is one minute

so 1/(24*60*60*2) is 1/2 second

You need to use a decimal point somewhere to force a floating point number

Not sure if this will work worth a shot for milliseconds

Application.Wait (Now + 0.000001) 

I used an approach described by Eric Daugherty: I created a special servlet that always answers with 403 code and put its mapping before the general one.

Mapping fragment:

  <servlet>
    <servlet-name>generalServlet</servlet-name>
    <servlet-class>project.servlet.GeneralServlet</servlet-class>
  </servlet>
 <servlet>
    <servlet-name>specialServlet</servlet-name>
    <servlet-class>project.servlet.SpecialServlet</servlet-class>
 </servlet>
 <servlet-mapping>
    <servlet-name>specialServlet</servlet-name>
    <url-pattern>/resources/restricted/*</url-pattern>
 </servlet-mapping>
 <servlet-mapping>
    <servlet-name>generalServlet</servlet-name>
    <url-pattern>/resources/*</url-pattern>
 </servlet-mapping>

And the servlet class:

public class SpecialServlet extends HttpServlet {
    public SpecialServlet() {
        super();
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.sendError(HttpServletResponse.SC_FORBIDDEN);
    }
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.sendError(HttpServletResponse.SC_FORBIDDEN);
    }
}

Java automatically interns String literals. This means that in many cases, the == operator appears to work for Strings in the same way that it does for ints or other primitive values.

Since interning is automatic for String literals, the intern() method is to be used on Strings constructed with new String()

Using your example:

String s1 = "Rakesh";
String s2 = "Rakesh";
String s3 = "Rakesh".intern();
String s4 = new String("Rakesh");
String s5 = new String("Rakesh").intern();

if ( s1 == s2 ){
    System.out.println("s1 and s2 are same");  // 1.
}

if ( s1 == s3 ){
    System.out.println("s1 and s3 are same" );  // 2.
}

if ( s1 == s4 ){
    System.out.println("s1 and s4 are same" );  // 3.
}

if ( s1 == s5 ){
    System.out.println("s1 and s5 are same" );  // 4.
}

will return:

s1 and s2 are same
s1 and s3 are same
s1 and s5 are same

In all the cases besides of s4 variable, a value for which was explicitly created using new operator and where intern method was not used on it's result, it is a single immutable instance that's being returned JVM's string constant pool.

Refer to JavaTechniques "String Equality and Interning" for more information.

Just set options :

• CURLOPT_HEADER, 0

• CURLOPT_RETURNTRANSFER, 1

and use curl_getinfo with CURLINFO_HTTP_CODE (or no opt param and you will have an associative array with all the informations you want)

More at : http://php.net/manual/fr/function.curl-getinfo.php

I've not tried this myself, but try setting:

height : 36px; //for other browsers
line-height: 36px; // for IE

Where 36px is the height of your input.

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

I think the only way is by using internel PHP code like MANOJ and Fernando suggest.

curl post/get in php file on your server --> call this php file with ajax

The PHP file let say (fb.php):

$commentdata=$_GET['commentdata'];
$fbUrl="https://graph.facebook.com/16453004404_481759124404/comments?access_token=my_token";
curl_setopt($ch, CURLOPT_URL,$fbUrl);
curl_setopt($ch, CURLOPT_POST, 1);
// POST data here
curl_setopt($ch, CURLOPT_POSTFIELDS,
        "message=".$commentdata);

// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);
echo $server_output;
curl_close ($ch);

Than use AJAX GET to

fb.php?commentmeta=your comment goes here

from your server.

Or do this with simple HTML and JavaScript from externel server:

Message: <input type="text" id="message">
<input type="submit" onclick='PostMessage()'>
<script>
function PostMessage() {
var comment = document.getElementById('message').value;
    window.location.assign('http://yourdomain.tld/fb.php?commentmeta='+comment)
}
</script>

The name of an array is the address of its first element, so name is a pointer to memory containing the string "siva".

Also you don't need a pointer to display a character; you are just electing to use it directly from the array in this case. You could do this instead:

char c = *name;
printf("%c\n", c);

I recode again the code and now you can create an .xls file, later you can convert to Excel 2003 Open XML Format.

tl;dr

record Person ( String name , int age ) {}  
if( 
    new Person( "Carol" , 27 )              // Compiler auto-generates implicitly the constructor.
    .equals(                                // Compiler auto-generates implicitly the `equals` method.
        new Person( "Carol" , 42 ) 
    ) 
)                                           // Returns `false`, as the name matches but the age differs.
{ … }

Details

While your specific problem is solved (using == for equality test between int primitive values), there is an alternative that eliminates the need to write that code.

record

Java 16 brings the record feature.

A record is a brief way to write a class whose main purpose is to transparently and immutably carry data. The compiler implicitly creates the constructor, getters, equals & hashCode, and toString.

equals method provided automatically

The default implicit equals method compares each and every member field that you declared for the record. The members can be objects or primitives, both types are automatically compared in the default equals method.

For example, if you have a Person record carrying two fields, name & age, both of those fields are automatically compared to determine equality between a pair of Person objects.

public record Person ( String name , int age ) {}

Try it.

Person alice = new Person( "Alice" , 23 ) ;
Person alice2 = new Person( "Alice" , 23 ) ;
Person bob = new Person( "Bob" , 19 ) ;

boolean samePerson1 = alice.equals( alice2 ) ;  // true.
boolean samePerson2 = alice.equals( bob ) ;  // false.

You can override the equals method on a record, if you want a behavior other than the default. But if you do override equals, be sure to override hashCode for consistent logic, as you would for a conventional Java class. And, think twice: Whenever adding methods to a record, reconsider if a record structure is really appropriate to that problem domain.

Tip: A record can be defined within another class, and even locally within a method.

First argument in update method is SyntheticEvent object that contains common properties and methods to any event, it is not reference to React component where there is property props.

if you need pass argument to update method you can do it like this

onClick={ (e) => this.props.onClick(e, 'home', 'Home') }

and get these arguments inside update method

update(e, space, txt){
   console.log(e.target, space, txt);
}

Example

event.target gives you the native DOMNode, then you need to use the regular DOM APIs to access attributes. For instance getAttribute or dataset

<button 
  data-space="home" 
  className="home" 
  data-txt="Home" 
  onClick={ this.props.onClick } 
/> 
  Button
</button>

onClick(e) {
   console.log(e.target.dataset.txt, e.target.dataset.space);
}

Example

Take a look at JSMPEG project. There is a great idea implemented there — to decode MPEG in the browser using JavaScript. Bytes from encoder (FFMPEG, for example) can be transfered to browser using WebSockets or Flash, for example. If community will catch up, I think, it will be the best HTML5 live video streaming solution for now.

Since the question is so popular, it may be useful to add on what to do if you want to control the type property name and its value.

The long way is to write custom JsonConverters to handle (de)serialization by manually checking and setting the type property.

A simpler way is to use JsonSubTypes, which handles all the boilerplate via attributes:

[JsonConverter(typeof(JsonSubtypes), "Sound")]
[JsonSubtypes.KnownSubType(typeof(Dog), "Bark")]
[JsonSubtypes.KnownSubType(typeof(Cat), "Meow")]
public class Animal
{
    public virtual string Sound { get; }
    public string Color { get; set; }
}

public class Dog : Animal
{
    public override string Sound { get; } = "Bark";
    public string Breed { get; set; }
}

public class Cat : Animal
{
    public override string Sound { get; } = "Meow";
    public bool Declawed { get; set; }
}

1. Your jsfiddle uses background-image instead of background
2. It seems to be a case of "not supported by this browser yet".

This works in Opera : http://jsfiddle.net/ZNsbU/5/
But it doesn't work in FF5 nor IE8. (yay for outdated browsers :D )

Code :

body {
  background:url(http://www.google.com/intl/en_com/images/srpr/logo3w.png) 400px 200px / 600px 400px no-repeat;
}

You could do it like this :

body {
    background:url(http://www.google.com/intl/en_com/images/srpr/logo3w.png) 400px 400px no-repeat;
    background-size:20px 20px
}

Which works in FF5 and Opera but not in IE8.

#! /bin/sh
echo "$(cd "$(dirname "$1")"; pwd -P)/$(basename "$1")"

Can you place the #ulId in the document prior to the ajax load (with css display: none;), or wrap it in a containing div (with css display: none;), then just load the inner html during ajax page load, that way the scroll event will be linked to the div that is already there prior to the ajax?

Then you can use:

$('#ulId').on('scroll',function(){ console.log('Event Fired'); })

obviously replacing ulId with whatever the actual id of the scrollable div is.

Then set css display: block; on the #ulId (or containing div) upon load?

f you want to use $.getJSON() you can add the following before the call :

$.ajaxSetup({
    scriptCharset: "utf-8",
    contentType: "application/json; charset=utf-8"
});

I encountered this problem today as well. I am using Windows and the system language by default is Chinese. Hence, someone may encounter this Unicode error similarly. Simply add encoding = 'utf-8':

with open("test.html", "r", encoding='utf-8') as f:
    text= f.read()

Create a folder ${USER_HOME}/.mvn and put a file called maven.config in it.

The content should be:

-Dmaven.wagon.http.ssl.insecure=true
-Dmaven.wagon.http.ssl.allowall=true
-Dmaven.wagon.http.ssl.ignore.validity.dates=true

Hope this helps.

I know this is old question but...

As Raymond Hettinger said, it should be called while/no_break instead of while/else.
I find it easy to understeand if you look at this snippet.

n = 5
while n > 0:
    print n
    n -= 1
    if n == 2:
        break
if n == 0:
    print n

Now instead of checking condition after while loop we can swap it with else and get rid of that check.

n = 5
while n > 0:
    print n
    n -= 1
    if n == 2:
        break
else:  # read it as "no_break"
    print n

I always read it as while/no_break to understand the code and that syntax makes much more sense to me.

Use setInterval instead of setTimeout. Though in this case either will be fine but setTimeout inherently triggers only once setInterval continues indefinitely.

<script language="javascript">
setInterval(function(){
   window.location.reload(1);
}, 30000);
</script>

It works fine for me...

This is default database :

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'mydatabase',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => TRUE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

Add another database at the bottom of database.php file

$db['second'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'mysecond',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => TRUE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

In autoload.php config file

$autoload['libraries'] = array('database', 'email', 'session');

The default database is worked fine by autoload the database library but second database load and connect by using constructor in model and controller...

<?php
    class Seconddb_model extends CI_Model {
        function __construct(){
            parent::__construct();
            //load our second db and put in $db2
            $this->db2 = $this->load->database('second', TRUE);
        }

        public function getsecondUsers(){
            $query = $this->db2->get('members');
            return $query->result(); 
        }

    }
?>

As it turns out, Git is smart enough not to drop a stash if it doesn't apply cleanly. I was able to get to the desired state with the following steps:

1. To unstage the merge conflicts: git reset HEAD . (note the trailing dot)
2. To save the conflicted merge (just in case): git stash
3. To return to master: git checkout master
4. To pull latest changes: git fetch upstream; git merge upstream/master
5. To correct my new branch: git checkout new-branch; git rebase master
6. To apply the correct stashed changes (now 2nd on the stack): git stash apply stash@{1}

Adding to assylias's answer - assylias shows us D.ITEMS is a method that returns an array. Knowing that, we don't need the variant array a(i) [See caveat below]. We just need to use the proper array syntax.

For i = 0 To d.Count - 1
    s = d.Items()(i)
    Debug.Print s
Next i()

KEYS works the same way

For i = 0 To d.Count - 1
    Debug.Print d.Keys()(i), d.Items()(i)
Next i

This syntax is also useful for the SPLIT function which may help make this clearer. SPLIT also returns an array with lower bounds at 0. Thus, the following prints "C".

Debug.Print Split("A,B,C,D", ",")(2)

SPLIT is a function. Its parameters are in the first set of parentheses. Methods and Functions always use the first set of parentheses for parameters, even if no parameters are needed. In the example SPLIT returns the array {"A","B","C","D"}. Since it returns an array we can use a second set of parentheses to identify an element within the returned array just as we would any array.

Caveat: This shorter syntax may not be as efficient as using the variant array a() when iterating through the entire dictionary since the shorter syntax invokes the dictionary's Items method with each iteration. The shorter syntax is best for plucking a single item by number from a dictionary.

It is possible to send Emails without using any heavy libraries I have included my example here.

lightweight SMTP Email sender for PHP

Tested in both environments production and development.

and most importantly emails will not go to spam unless your IP is blacklisted by the server.

cheers.

There are several key differences.

update is used on a queryset, so it is possible to update multiple objects at once.

As @FallenAngel pointed out, there are differences in how custom save() method triggers, but it is also important to keep in mind signals and ModelManagers. I have build a small testing app to show some valuable differencies. I am using Python 2.7.5, Django==1.7.7 and SQLite, note that the final SQLs may vary on different versions of Django and different database engines.

Ok, here's the example code.

models.py:

from __future__ import print_function
from django.db import models
from django.db.models import signals
from django.db.models.signals import pre_save, post_save
from django.dispatch import receiver

__author__ = 'sobolevn'

class CustomManager(models.Manager):
    def get_queryset(self):
        super_query = super(models.Manager, self).get_queryset()
        print('Manager is called', super_query)
        return super_query


class ExtraObject(models.Model):
    name = models.CharField(max_length=30)

    def __unicode__(self):
        return self.name


class TestModel(models.Model):

    name = models.CharField(max_length=30)
    key = models.ForeignKey('ExtraObject')
    many = models.ManyToManyField('ExtraObject', related_name='extras')

    objects = CustomManager()

    def save(self, *args, **kwargs):
        print('save() is called.')
        super(TestModel, self).save(*args, **kwargs)

    def __unicode__(self):
        # Never do such things (access by foreing key) in real life,
        # because it hits the database.
        return u'{} {} {}'.format(self.name, self.key.name, self.many.count())


@receiver(pre_save, sender=TestModel)
@receiver(post_save, sender=TestModel)
def reicever(*args, **kwargs):
    print('signal dispatched')

views.py:

def index(request):
    if request and request.method == 'GET':

        from models import ExtraObject, TestModel

        # Create exmple data if table is empty:
        if TestModel.objects.count() == 0:
            for i in range(15):
                extra = ExtraObject.objects.create(name=str(i))
                test = TestModel.objects.create(key=extra, name='test_%d' % i)
                test.many.add(test)
                print test

        to_edit = TestModel.objects.get(id=1)
        to_edit.name = 'edited_test'
        to_edit.key = ExtraObject.objects.create(name='new_for')
        to_edit.save()

        new_key = ExtraObject.objects.create(name='new_for_update')
        to_update = TestModel.objects.filter(id=2).update(name='updated_name', key=new_key)
        # return any kind of HttpResponse

That resuled in these SQL queries:

# to_edit = TestModel.objects.get(id=1):
QUERY = u'SELECT "main_testmodel"."id", "main_testmodel"."name", "main_testmodel"."key_id" 
FROM "main_testmodel" 
WHERE "main_testmodel"."id" = %s LIMIT 21' 
- PARAMS = (u'1',)

# to_edit.save():
QUERY = u'UPDATE "main_testmodel" SET "name" = %s, "key_id" = %s 
WHERE "main_testmodel"."id" = %s' 
- PARAMS = (u"'edited_test'", u'2', u'1')

# to_update = TestModel.objects.filter(id=2).update(name='updated_name', key=new_key):
QUERY = u'UPDATE "main_testmodel" SET "name" = %s, "key_id" = %s 
WHERE "main_testmodel"."id" = %s' 
- PARAMS = (u"'updated_name'", u'3', u'2')

We have just one query for update() and two for save().

Next, lets talk about overriding save() method. It is called only once for save() method obviously. It is worth mentioning, that .objects.create() also calls save() method.

But update() does not call save() on models. And if no save() method is called for update(), so the signals are not triggered either. Output:

Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

# TestModel.objects.get(id=1):
Manager is called [<TestModel: edited_test new_for 0>]
Manager is called [<TestModel: edited_test new_for 0>]
save() is called.
signal dispatched
signal dispatched

# to_update = TestModel.objects.filter(id=2).update(name='updated_name', key=new_key):
Manager is called [<TestModel: edited_test new_for 0>]

As you can see save() triggers Manager's get_queryset() twice. When update() only once.

Resolution. If you need to "silently" update your values, without save() been called - use update. Usecases: last_seen user's field. When you need to update your model properly use save().

The solution provided by Joe Steanelli works, but making a list of columns is inconvenient when dozens or hundreds of columns are involved. Here's how to get column list of table my_table in my_schema.

-- override GROUP_CONCAT limit of 1024 characters to avoid a truncated result
set session group_concat_max_len = 1000000;

select GROUP_CONCAT(CONCAT("'",COLUMN_NAME,"'"))
from INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'my_table'
AND TABLE_SCHEMA = 'my_schema'
order BY ORDINAL_POSITION

Now you can copy & paste the resulting row as first statement in Joe's method.

Except for @Prashant's answer, the above answers have been answered incorrectly. Where is the "replace" feature of the answer? The OP asked, "After that, I'd like to create a new string between that and something else".

Based on @Oscar's excellent response, I have expanded his function to be a "Search And Replace" function in one.

I think @Prashant's answer should have been the accepted answer by the OP, as it does a replace.

Anyway, I've called my variant - ReplaceBetween().

public static string ReplaceBetween(string strSource, string strStart, string strEnd, string strReplace)
{
    int Start, End;
    if (strSource.Contains(strStart) && strSource.Contains(strEnd))
    {
        Start = strSource.IndexOf(strStart, 0) + strStart.Length;
        End = strSource.IndexOf(strEnd, Start);
        string strToReplace = strSource.Substring(Start, End - Start);
        string newString = strSource.Concat(Start,strReplace,End - Start);
        return newString;
    }
    else
    {
        return string.Empty;
    }
}

For those using Rails(4.2) Internationalization (I18n):

Set the placeholder attribute to true:

f.text_field :attr, placeholder: true

and in your local file (ie. en.yml):

en:
  helpers:
    placeholder:
      model_name:
        attr: "some placeholder text"

My own template functions which performs upper / lower case.

#include <string>
#include <algorithm>

//
//  Lowercases string
//
template <typename T>
std::basic_string<T> lowercase(const std::basic_string<T>& s)
{
    std::basic_string<T> s2 = s;
    std::transform(s2.begin(), s2.end(), s2.begin(), tolower);
    return std::move(s2);
}

//
// Uppercases string
//
template <typename T>
std::basic_string<T> uppercase(const std::basic_string<T>& s)
{
    std::basic_string<T> s2 = s;
    std::transform(s2.begin(), s2.end(), s2.begin(), toupper);
    return std::move(s2);
}

Thats how it works stored procedures run in order, you don't need begin just something like

exec dbo.sp1
exec dbo.sp2

In Swift 4, if you are traversing through your DataModel array, make sure your data model conforms to Equatable Protocol , implement the lhs=rhs method , and only then you can use ".index(of" . For example

class Photo : Equatable{
    var imageURL: URL?
    init(imageURL: URL){
        self.imageURL = imageURL
    }

    static func == (lhs: Photo, rhs: Photo) -> Bool{
        return lhs.imageURL == rhs.imageURL
    }
}

And then,

let index = self.photos.index(of: aPhoto)

Those who suggested chmod 400 id_rsa.pub did not sound right at all. It was quite possible that op used pub key instead of private key to ssh.

So it might be as simple as ssh -i /Users/tudouya/.ssh/vm/vm_id_rsa (the private key) user@host to fix it.

ListItem item = ddlComputedliat1.Items.FindByText("Amt D");
if (item == null) {
    ddlComputedliat1.Items.Insert(1, lblnewamountamt.Text);
}

A work around you can try is defining a getInstance() method in your interface so the implementer is aware of what parameters need to be handled. It isn't as solid as an abstract class, but it allows more flexibility as being an interface.

However this workaround does require you to use the getInstance() to instantiate all objects of this interface.

E.g.

public interface Module {
    Module getInstance(Receiver receiver);
}

Try this:

String hourMinute = DateTime.Now.ToString("HH:mm");

Now you will get the time in hour:minute format.

I meet the same problem and no one of the solutions detailed here worked for me ... First of all I had an error 413 Entity too large so I updated my nginx.conf as following :

http {
        # Increase request size
        client_max_body_size 10m;

        ##
        # Basic Settings
        ##

        types_hash_max_size 2048;
        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;

        ssl_prefer_server_ciphers on;

        ##
        # Logging Settings
        ##

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;

        # gzip_vary on;
        # gzip_proxied any;
        # gzip_comp_level 6;

        # gzip_http_version 1.1;
        # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

        ##
        # Virtual Host Configs
        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;

        ##
        # Proxy settings

        proxy_send_timeout 1000;
        proxy_read_timeout 1000;
        send_timeout 1000;
}

So I only updated the http part, and now I meet the error 502 Bad Gateway and when I display /var/log/nginx/error.log I got the famous "upstream prematurely closed connection while reading response header from upstream"

What is really mysterious for me is that the request works when I run it with virtualenv on my server and send the request to the : IP:8000/nameOfTheRequest

Thanks for reading

I was getting this error on a Spring Boot application where a @RestController ApplicationInfoResource had a nested class ApplicationInfo.

It seems the Spring Boot Dev Tools was using a different class loader.

The exception I was getting

2017-05-01 17:47:39.588 WARN 1516 --- [nio-8080-exec-9] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.IllegalAccessError: tried to access class com.gt.web.rest.ApplicationInfo from class com.gt.web.rest.ApplicationInfoResource$$EnhancerBySpringCGLIB$$59ce500c

Solution

I moved the nested class ApplicationInfo to a separate .java file and got rid of the problem.

i did this:

$("#myModal").modal({}).draggable();

and it make my very standard/basic modal draggable.

not sure how/why it worked, but it did.

Request.Url.Segments.Last()

Another option.

You can use this one also (sets a special listener to be called when an action is performed on the EditText), it works both for DONE and RETURN:

max.setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_DONE)) {
                Log.i(TAG,"Enter pressed");
            }    
            return false;
        }
    });

I ran into issues on one of my servers querying MSDB tables (aka code listed above) as one of my jobs would come up running, but it was not. There is a system stored procedure that returns the execution status, but one cannot do a insert exec statement without an error. Inside that is another system stored procedure that can be used with an insert exec statement.

INSERT INTO #Job
EXEC master.dbo.xp_sqlagent_enum_jobs 1,dbo

And the table to load it into:

CREATE TABLE #Job 
               (job_id               UNIQUEIDENTIFIER NOT NULL,  
               last_run_date         INT              NOT NULL,  
               last_run_time         INT              NOT NULL,  
               next_run_date         INT              NOT NULL,  
               next_run_time         INT              NOT NULL,  
               next_run_schedule_id  INT              NOT NULL,  
               requested_to_run      INT              NOT NULL, -- BOOL  
               request_source        INT              NOT NULL,  
               request_source_id     sysname          COLLATE database_default NULL,  
               running               INT              NOT NULL, -- BOOL  
               current_step          INT              NOT NULL,  
               current_retry_attempt INT              NOT NULL,  
               job_state             INT              NOT NULL) 

How about this?

var obj = {},
var isEmpty = !obj;
var hasContent = !!obj

I have had the same problem.

In my case, since I have the original repository in my local machine, I have made a copy in a new folder without any hidden file (.git, .gitignore).

Finally I have added the .gitignore file to the new created folder.

Then I have created and added the new repository from the local path (in my case using GitHub Desktop).

A variation to the pointer-events: none; solution, which resolves the issue of the input still being accessible via it's labeled control or tabindex, is to wrap the input in a div, which is styled as a disabled text input, and setting input { visibility: hidden; } when the input is "disabled".
Ref: https://developer.mozilla.org/en-US/docs/Web/CSS/visibility#Values

div.dependant {_x000D_
  border: 0.1px solid rgb(170, 170, 170);_x000D_
  background-color: rgb(235,235,228);_x000D_
  box-sizing: border-box;_x000D_
}_x000D_
input[type="checkbox"]:not(:checked) ~ div.dependant:first-of-type {_x000D_
  display: inline-block;_x000D_
}_x000D_
input[type="checkbox"]:checked ~ div.dependant:first-of-type {_x000D_
  display: contents;_x000D_
}_x000D_
input[type="checkbox"]:not(:checked) ~ div.dependant:first-of-type > input {_x000D_
  visibility: hidden;_x000D_
}

<form>_x000D_
  <label for="chk1">Enable textbox?</label>_x000D_
  <input id="chk1" type="checkbox" />_x000D_
  <br />_x000D_
  <label for="text1">Input textbox label</label>_x000D_
  <div class="dependant">_x000D_
    <input id="text1" type="text" />_x000D_
  </div>_x000D_
</form>

The disabled styling applied in the snippet above is taken from the Chrome UI and may not be visually identical to disabled inputs on other browsers. Possibly it can be customised for individual browsers using engine-specific CSS extension -prefixes. Though at a glance, I don't think it could:
Microsoft CSS extensions, Mozilla CSS extensions, WebKit CSS extensions

It would seem far more sensible to introduce an additional value visibility: disabled or display: disabled or perhaps even appearance: disabled, given that visibility: hidden already affects the behavior of the applicable elements any associated control elements.

const path = require('path');

const express = require('express');

const app = new express();
app.use(express.static('/media'));

app.get('/', (req, res) => {
    res.sendFile(path.resolve(__dirname, 'media/page/', 'index.html'));
});

app.listen(4000, () => {
    console.log('App listening on port 4000')
})

Tried @RameshVel solution but I could not pass arguments in my console application. If anyone experiences the same problem here is a solution:

using System.Diagnostics;

Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;
cmd.Start();

cmd.StandardInput.WriteLine("echo Oscar");
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
cmd.WaitForExit();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());

To show months as Jan 2017 Feb 2017 etc:

scale_x_date(date_breaks = "1 month", date_labels =  "%b %Y") 

Angle the dates if they take up too much space:

theme(axis.text.x=element_text(angle=60, hjust=1))

AFAIK you must reformat your String in ISO format to be able to cast it as a Date:

cast(concat(substr(STR_DMY,7,4), '-',
            substr(STR_DMY,1,2), '-',
            substr(STR_DMY,4,2)
           )
     as date
     ) as DT

To display a Date as a String with specific format, then it's the other way around, unless you have Hive 1.2+ and can use date_format()

=> did you check the documentation by the way?

I think you approach is correct. Historical table should be a copy of the main table without indexes, make sure you have update timestamp in the table as well.

If you try the other approach soon enough you will face problems:

• maintenance overhead
• more flags in selects
• queries slowdown
• growth of tables, indexes

check the following code to call one activity from another.

Intent intent = new Intent(CurrentActivity.this, OtherActivity.class);
CurrentActivity.this.startActivity(intent);

you can use str.index too:

>>> 'sdfasdf'.index('cc')
Traceback (most recent call last):
  File "<pyshell#144>", line 1, in <module>
    'sdfasdf'.index('cc')
ValueError: substring not found
>>> 'sdfasdf'.index('df')
1

You need the * so it says "zero or more of the previous character" and this should do it:

var reg = new RegExp('^\\d*$');

Call the class which has main() method.

java MyClass

Here MyClass will have public static void main() method.

I've used it a lot in the past to work with input and output streams. You can nest them nicely and it takes away a lot of the potential problems you usually run into (by automatically calling dispose). For example:

        using (FileStream fs = new FileStream("c:\file.txt", FileMode.Open))
        {
            using (BufferedStream bs = new BufferedStream(fs))
            {
                using (System.IO.StreamReader sr = new StreamReader(bs))
                {
                    string output = sr.ReadToEnd();
                }
            }
        }

It is a bug in IE8.

Starting with your second question: “margin: 0 auto” centers a block, but only when width of the block is set to be less that width of parent. Usually, they get to be the same. That is why text in the example below is not centered.

<div style="height: 100px; width: 500px; background-color: Yellow;">    
    <b style="display: block; margin: 0 auto; ">text</b>
</div>

Once the display style of the b element is set to block, its width defaults to the parents width. CSS spec 10.3.3 Block-level, non-replaced elements in normal flow describes how: “If 'width' is set to 'auto', any other 'auto' values become '0' and 'width' follows from the resulting equality.” The equality mentioned there is

'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' = width of containing block

So, normally all autos result in a block width being equal to the width of containing block.

However, this calculation should not be applied to INPUT, which is a replaced element. Replaced elements are covered by 10.3.4 Block-level, replaced elements in normal flow. Text there says: “The used value of 'width' is determined as for inline replaced elements.” The relevant part of 10.3.2 Inline, replaced elements is: “if 'width' has a computed value of 'auto', and the element has an intrinsic width, then that intrinsic width is the used value of 'width'”.

I guess that the scenario CSS cares about is IMG element. Stackoverflow logo in this example will be centered by all browsers.

<div style="height: 100px; width: 500px; background-color: Yellow;">    
    <img style="display: block; margin: 0 auto; " border="0" src="http://stackoverflow.com/content/img/so/logo.png" alt="">
</div>

INPUT element should behave the same way.

Here is another option

$array = [1=>'one', 2=>'two', 3=>'there'];
$array = array_flip($array);
echo $array['one']; 

I implemented a hasOne relation in my parent class, defined both the foreign and local key, it returned an object but the columns of the child must be accessed as an array.
i.e. $parent->child['column']
Kind of confusing.

Here is code that will upload multiple images at once, into a specific folder!

The HTML:

<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">

</ul>

The PHP:

<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
    $name = $_FILES["images"]["name"][$key];
    //$ext = pathinfo($name, PATHINFO_EXTENSION);
    $name = explode("_", $name);
    $imagename='';
    foreach($name as $letter){
        $imagename .= $letter;
    }

    move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" .  $imagename);

}
}


echo "<h2>Successfully Uploaded Images</h2>";

And finally, the JavaSCript/Ajax:

(function () {
var input = document.getElementById("images"), 
    formdata = false;

function showUploadedItem (source) {
    var list = document.getElementById("image-list"),
        li   = document.createElement("li"),
        img  = document.createElement("img");
    img.src = source;
    li.appendChild(img);
    list.appendChild(li);
}   

if (window.FormData) {
    formdata = new FormData();
    document.getElementById("btn").style.display = "none";
}

input.addEventListener("change", function (evt) {
    document.getElementById("response").innerHTML = "Uploading . . ."
    var i = 0, len = this.files.length, img, reader, file;

    for ( ; i < len; i++ ) {
        file = this.files[i];

        if (!!file.type.match(/image.*/)) {
            if ( window.FileReader ) {
                reader = new FileReader();
                reader.onloadend = function (e) { 
                    showUploadedItem(e.target.result, file.fileName);
                };
                reader.readAsDataURL(file);
            }
            if (formdata) {
                formdata.append("images[]", file);
            }
        }   
    }

    if (formdata) {
        $.ajax({
            url: "submit_image.php",
            type: "POST",
            data: formdata,
            processData: false,
            contentType: false,
            success: function (res) {
                document.getElementById("response").innerHTML = res;
            }
        });
    }
}, false);
}());

Hope this helps

So you're trying to grab numeric values that are preceded by the token "%download%#"?

Try this pattern:

(?<=%download%#)\d+

That should work. I don't think # or % are special characters in .NET Regex, but you'll have to either escape the backslash like \\ or use a verbatim string for the whole pattern:

var regex = new Regex(@"(?<=%download%#)\d+");
return regex.Matches(strInput);

Tested here: http://rextester.com/BLYCC16700

NOTE: The lookbehind assertion (?<=...) is important because you don't want to include %download%# in your results, only the numbers after it. However, your example appears to require it before each string you want to capture. The lookbehind group will make sure it's there in the input string, but won't include it in the returned results. More on lookaround assertions here.

You want to set the execution policy on your machine using Set-ExecutionPolicy:

Set-ExecutionPolicy Unrestricted

You may want to investigate the various execution policies to see which one is right for you. Take a look at the "help about_signing" for more information.

In Python, execution does NOT have to begin at main. The first line of "executable code" is executed first.

def main():
    print("main code")

def meth1():
    print("meth1")

meth1()
if __name__ == "__main__":main() ## with if

Output -

meth1
main code

More on main() - http://ibiblio.org/g2swap/byteofpython/read/module-name.html

A module's __name__

Every module has a name and statements in a module can find out the name of its module. This is especially handy in one particular situation - As mentioned previously, when a module is imported for the first time, the main block in that module is run. What if we want to run the block only if the program was used by itself and not when it was imported from another module? This can be achieved using the name attribute of the module.

Using a module's __name__

#!/usr/bin/python
# Filename: using_name.py

if __name__ == '__main__':
    print 'This program is being run by itself'
else:
    print 'I am being imported from another module'

Output -

$ python using_name.py
This program is being run by itself
$ python
>>> import using_name
I am being imported from another module
>>>

How It Works -

Every Python module has it's __name__ defined and if this is __main__, it implies that the module is being run standalone by the user and we can do corresponding appropriate actions.

Here’s the JavaScript equivalent:

var i = null;
var j = i || 10; //j is now 10

Note that the logical operator || does not return a boolean value but the first value that can be converted to true.

Additionally use an array of objects instead of one single object:

var options = {
    filters: [
        {
            name: 'firstName',
            value: 'abc'
        }
    ]
};
var filter  = options.filters[0] || '';  // is {name:'firstName', value:'abc'}
var filter2 = options.filters[1] || '';  // is ''

That can be accessed by index.

If you are using the JPA annotations to create the entities and then make sure that the table name is mapped along with @Table annotation instead of @Entity.

Incorrectly mapped :

@Entity(name="DB_TABLE_NAME")
public class DbTableName implements Serializable {
   ....
   ....
}

Correctly mapped entity :

@Entity
@Table(name="DB_TABLE_NAME")
public class DbTableName implements Serializable {
   ....
   ....
}

Your byte array is too small. Each pixel takes up 4 bytes, not just 1, so multiply your size * 4 so that the array is big enough.

USE BINARY_CHECKSUM

SELECT 
FROM Users
WHERE   
    BINARY_CHECKSUM(Username) = BINARY_CHECKSUM(@Username)
    AND BINARY_CHECKSUM(Password) = BINARY_CHECKSUM(@Password)

You can use finfo to accomplish this as of PHP 5.3:

<?php
$info = new finfo(FILEINFO_MIME_TYPE);
echo $info->file('myImage.jpg');
// prints "image/jpeg"

The FILEINFO_MIME_TYPE flag is optional; without it you get a more verbose string for some files; (apparently some image types will return size and colour depth information). Using the FILEINFO_MIME flag returns the mime-type and encoding if available (e.g. image/png; charset=binary or text/x-php; charset=us-ascii). See this site for more info.

Using HTML 5 Drag and Drop
You can easily archive this using HTML 5 drag and drop feature along with angular directives.

1. Enable drag by setting draggable = true.
2. Add directives for parent container and child items.
3. Override drag and drop functions - 'ondragstart' for parent and 'ondrop' for child.

Find the example below in which list is array of items.
HTML code:

    <div class="item_content" ng-repeat="item in list" draggrble-container>
        <div class="item" draggable-item draggable="true">{{item}}</div>
    </div>

Javascript:

    module.directive("draggableItem",function(){
     return {
      link:function(scope,elem,attr){
        elem[0].ondragstart = function(event){
            scope.$parent.selectedItem = scope.item;
        };
      }
     };
    });


    module.directive("draggrbleContainer",function(){
     return {
        link:function(scope,elem,attr){
            elem[0].ondrop = function(event){
                event.preventDefault();
                let selectedIndex = scope.list.indexOf(scope.$parent.selectedItem);
                let newPosition = scope.list.indexOf(scope.item);
                scope.$parent.list.splice(selectedIndex,1);
                scope.$parent.list.splice(newPosition,0,scope.$parent.selectedItem);
                scope.$apply();
            };
            elem[0].ondragover = function(event){
                event.preventDefault();

            };
        }
     };
    });

Slack has a cool way of making tabs small viewport friendly on some of their admin pages. I made something similar using bootstrap. It's kind of a tabs ? dropdown.

Demo: http://jsbin.com/nowuyi/1

Here's what it looks like on a big viewport:

Here's how it looks collapsed on a small viewport:

Here's how it looks expanded on a small viewport:

the HTML is exactly the same as default bootstrap tabs.

There is a small JS snippet, which requires jquery (and inserts two span elements into the DOM):

$.fn.responsiveTabs = function() {
  this.addClass('responsive-tabs');
  this.append($('<span class="glyphicon glyphicon-triangle-bottom"></span>'));
  this.append($('<span class="glyphicon glyphicon-triangle-top"></span>'));

  this.on('click', 'li.active > a, span.glyphicon', function() {
    this.toggleClass('open');
  }.bind(this));

  this.on('click', 'li:not(.active) > a', function() {
    this.removeClass('open');
  }.bind(this));
};

$('.nav.nav-tabs').responsiveTabs();

And then there is a lot of css (less):

@xs: 768px;


.responsive-tabs.nav-tabs {
  position: relative;
  z-index: 10;
  height: 42px;
  overflow: visible;
  border-bottom: none;

  @media(min-width: @xs) {
    border-bottom: 1px solid #ddd;
  }

  span.glyphicon {
    position: absolute;
    top: 14px;
    right: 22px;
    &.glyphicon-triangle-top {
      display: none;
    }
    @media(min-width: @xs) {
      display: none;
    }
  }

  > li {
    display: none;
    float: none;
    text-align: center;

    &:last-of-type > a {
      margin-right: 0;
    }

    > a {
      margin-right: 0;
      background: #fff;
      border: 1px solid #DDDDDD;

      @media(min-width: @xs) {
        margin-right: 4px;
      }
    }

    &.active {
      display: block;
      a {
        @media(min-width: @xs) {
          border-bottom-color: transparent; 
        }
        border: 1px solid #DDDDDD;
        border-radius: 2px;
      }
    }

    @media(min-width: @xs) {
      display: block;
      float: left;
    }

  }

  &.open {

    span.glyphicon {
      &.glyphicon-triangle-top {
        display: block;
        @media(min-width: @xs) {
          display: none;
        }
      }
      &.glyphicon-triangle-bottom {
        display: none;
      }
    }

    > li {
      display: block;

      a {
        border-radius: 0;
      }

      &:first-of-type a {
        border-radius: 2px 2px 0 0;
      }
      &:last-of-type a {
        border-radius: 0 0 2px 2px;
      }
    }
  }
}

Are you ssh'ing to a directory that's inside your work tree? If the root of your ssh mount point doesn't include the .git dir, then zsh won't be able to find git info. Make sure you're mounting something that includes the root of the repo.

As for GIT_DISCOVERY_ACROSS_FILESYSTEM, it doesn't do what you want. Git by default will stop at a filesystem boundary. If you turn that on (and it's just an env var), then git will cross the filesystem boundary and keep looking. However, that's almost never useful, because you'd be implying that you have a .git directory on your local machine that's somehow meant to manage a work tree that's comprised partially of an sshfs mount. That doesn't make much sense.

Just say (current object) .attributes

.attributes returns a hash of any object. And it's much cleaner too.

Weird, just had simmilar issue, went here http://www.microsoft.com/en-us/download/confirmation.aspx?id=30679 downloaded and installed vcredist_x86 (i'm using 32bit apache) and it works like a charm.

Like this

SELECT DISTINCT Table1.Column1
FROM Table1
WHERE NOT EXISTS( SELECT * FROM Table2
    WHERE Table1.Column1 = Table2.Column1  )

You want NOT EXISTS, not "Not Equal"

By the way, you rarely want to write a FROM clause like this:

FROM Table1, Table2

as this means "FROM all combinations of every row in Table1 with every row in Table2..." Usually that's a lot more result rows than you ever want to see. And in the rare case that you really do want to do that, the more accepted syntax is:

FROM Table1 CROSS JOIN Table2

Here it is in Java:

public static void rotateInPlace(int[][] m) {
    for(int layer = 0; layer < m.length/2; layer++){
        int first = layer;
        int last = m.length - 1 - first;
        for(int i = first; i < last; i ++){
            int offset = i - first;
            int top = m[first][i];
            m[first][i] = m[last - offset][first];
            m[last - offset][first] = m[last][last - offset];
            m[last][last - offset] = m[i][last];
            m[i][last] = top;
        }
    }
}

The erase method on std::vector is overloaded, so it's probably clearer to call

vec.erase(vec.begin() + index);

when you only want to erase a single element.

You can use two ways to resolve this problem, first way that i think it as best way is replace importing segment of your code with bellow one:

import Home from './layouts/Home'

or export your component without default which is called named export like this

import React, { Component } from 'react';

class Home extends Component{
    render(){
        return(
        <p className="App-intro">
          Hello Man
        </p>
        )
    }
} 

export {Home};

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

For maintainability, I would attach the "blocking" handler on the element itself (in your case, the canvas).

theCanvas.onkeydown = function (e) {
    if (e.key === 'ArrowUp' || e.key === 'ArrowDown') {
        e.view.event.preventDefault();
    }
}

Why not simply do window.event.preventDefault()? MDN states:

window.event is a proprietary Microsoft Internet Explorer property which is only available while a DOM event handler is being called. Its value is the Event object currently being handled.

Maybe it's obvious for you guys but I scratched my head for a while because the folder didn't show up in the files app. I actually needed to store something in the folder. you could achieve this by

• saving some files into your document directory of the app
• move something from iCloud Drive to your app (in the move dialog the folder will show up). As soon as there are no files in your folder anymore, it's gonna disappear from the "on my iPad tab".

The two valid mains are int main() and int main(int, char*[]). Any thing else may or may not compile. If main doesn't explicitly return a value, 0 is implicitly returned.

There is a method, "hasOwnProperty", that exists on an object, but it's not recommended to call this method directly, because it might be sometimes that the object is null or some property exist on the object like: { hasOwnProperty: false }

So a better way would be:

// Good
var obj = {"bar": "here bar desc"}
console.log(Object.prototype.hasOwnProperty.call(obj, "bar"));

// Best
const has = Object.prototype.hasOwnProperty; // Cache the lookup once, in module scope.
console.log(has.call(obj, "bar"));

An abstract Interface is not as redundant as everyone seems to be saying, in theory at least.

An Interface can be extended, just as a Class can. If you design an Interface hierarchy for your application you may well have a 'Base' Interface, you extend other Interfaces from but do not want as an Object in itself.

Example:

public abstract interface MyBaseInterface {
    public String getName();
}

public interface MyBoat extends MyBaseInterface {
    public String getMastSize();
}

public interface MyDog extends MyBaseInterface {
    public long tinsOfFoodPerDay();
}

You do not want a Class to implement the MyBaseInterface, only the other two, MMyDog and MyBoat, but both interfaces share the MyBaseInterface interface, so have a 'name' property.

I know its kinda academic, but I thought some might find it interesting. :-)

It is really just a 'marker' in this case, to signal to implementors of the interface it wasn't designed to be implemented on its own. I should point out a compiler (At least the sun/ora 1.6 I tried it with) compiles a class that implements an abstract interface.

In my opinion the above answer do give some 'random' float, but none of them is truly a random float (i.e. they miss a part of the float representation). Before I will rush into my implementation lets first have a look at the ANSI/IEEE standard format for floats:

|sign (1-bit)| e (8-bits) | f (23-bit) |

the number represented by this word is (-1 * sign) * 2^e * 1.f

note the the 'e' number is a biased (with a bias of 127) number thus ranging from -127 to 126. The most simple (and actually most random) function is to just write the data of a random int into a float, thus

int tmp = rand();
float f = (float)*((float*)&tmp);

note that if you do float f = (float)rand(); it will convert the integer into a float (thus 10 will become 10.0).

So now if you want to limit the maximum value you can do something like (not sure if this works)

int tmp = rand();
float f = *((float*)&tmp);
tmp = (unsigned int)f       // note float to int conversion!
tmp %= max_number;
f -= tmp;

but if you look at the structure of the float you can see that the maximum value of a float is (approx) 2^127 which is way larger as the maximum value of an int (2^32) thus ruling out a significant part of the numbers that can be represented by a float. This is my final implementation:

/**
 * Function generates a random float using the upper_bound float to determine 
 * the upper bound for the exponent and for the fractional part.
 * @param min_exp sets the minimum number (closest to 0) to 1 * e^min_exp (min -127)
 * @param max_exp sets the maximum number to 2 * e^max_exp (max 126)
 * @param sign_flag if sign_flag = 0 the random number is always positive, if 
 *              sign_flag = 1 then the sign bit is random as well
 * @return a random float
 */
float randf(int min_exp, int max_exp, char sign_flag) {
    assert(min_exp <= max_exp);

    int min_exp_mod = min_exp + 126;

    int sign_mod = sign_flag + 1;
    int frac_mod = (1 << 23);

    int s = rand() % sign_mod;  // note x % 1 = 0
    int e = (rand() % max_exp) + min_exp_mod;
    int f = rand() % frac_mod;

    int tmp = (s << 31) | (e << 23) | f;

    float r = (float)*((float*)(&tmp));

    /** uncomment if you want to see the structure of the float. */
//    printf("%x, %x, %x, %x, %f\n", (s << 31), (e << 23), f, tmp, r);

    return r;
}

using this function randf(0, 8, 0) will return a random number between 0.0 and 255.0

Assuming that the length is same for each array in the second dimension, you can use

public class B {    
 public static void main(String [] main){
    int [] [] nir= new int [2] [3];
    System.out.println(nir[0].length);
 }
}

Found out these problems can be addressed by using

ObjectMapper#convertValue(Object fromValue, Class<T> toValueType)

As a result, the origal quuestion can be solved in a 2-step converison:

1. Demarshall the JSON back to an object - in which the Map<String, Object> is demarshalled as a HashMap<String, LinkedHashMap>, by using bjectMapper#readValue().

2. Convert inner LinkedHashMaps back to proper objects

ObjectMapper mapper = new ObjectMapper(); Class clazz = (Class) Class.forName(classType); MyOwnObject value = mapper.convertValue(value, clazz);

To prevent the 'classType' has to be known in advance, I enforced during marshalling an extra Map was added, containing <key, classNameString> pairs. So at unmarshalling time, the classType can be extracted dynamically.

If you want SSMS to maintain a query history, use the SSMS Tool Pack add on.

If you want to monitor the SQL Server for currently running queries, use SQL PRofiler as other have already suggested.

No. It is not possible to share the same port at a particular instant. But you can make your application such a way that it will make the port access at different instant.

If anything else doesn't help you. And maybe earlier you installed apache2 with info.php test file. Just clear App Data (cache,cookie) for localhost.

#include <termios.h>
#include <stdio.h>

static struct termios old, current;

/* Initialize new terminal i/o settings */
void initTermios(int echo) 
{
  tcgetattr(0, &old); /* grab old terminal i/o settings */
  current = old; /* make new settings same as old settings */
  current.c_lflag &= ~ICANON; /* disable buffered i/o */
  if (echo) {
      current.c_lflag |= ECHO; /* set echo mode */
  } else {
      current.c_lflag &= ~ECHO; /* set no echo mode */
  }
  tcsetattr(0, TCSANOW, &current); /* use these new terminal i/o settings now */
}

/* Restore old terminal i/o settings */
void resetTermios(void) 
{
  tcsetattr(0, TCSANOW, &old);
}

/* Read 1 character - echo defines echo mode */
char getch_(int echo) 
{
  char ch;
  initTermios(echo);
  ch = getchar();
  resetTermios();
  return ch;
}

/* Read 1 character without echo */
char getch(void) 
{
  return getch_(0);
}

/* Read 1 character with echo */
char getche(void) 
{
  return getch_(1);
}

/* Let's test it out */
int main(void) {
  char c;
  printf("(getche example) please type a letter: ");
  c = getche();
  printf("\nYou typed: %c\n", c);
  printf("(getch example) please type a letter...");
  c = getch();
  printf("\nYou typed: %c\n", c);
  return 0;
}

Output:

(getche example) please type a letter: g
You typed: g
(getch example) please type a letter...
You typed: g

Possibly not applicable for your situation, but here's the jQuery function I use for reloading external stylesheets:

/**
 * Forces a reload of all stylesheets by appending a unique query string
 * to each stylesheet URL.
 */
function reloadStylesheets() {
    var queryString = '?reload=' + new Date().getTime();
    $('link[rel="stylesheet"]').each(function () {
        this.href = this.href.replace(/\?.*|$/, queryString);
    });
}

Use defaultdict instead:

from collections import defaultdict
data = defaultdict(list)
data[1].append('hello')

This way you don't have to initialize all the keys you want to use to lists beforehand.

What is happening in your example is that you use one (mutable) list:

alist = [1]
data = dict.fromkeys(range(2), alist)
alist.append(2)
print data

would output {0: [1, 2], 1: [1, 2]}.

Working on a project I was stuck for some time on this concept - I ended up with a similar answer to Method 1 by @GSerg that worked great. Essentially I defined two formula ranges (using a few variables) and then used the Union concept. My example is from a larger project that I'm working on but hopefully the portion of code below can help some other people who might not know how to use the Union concept in conjunction with defined ranges and variables. I didn't include the entire code because at this point it's fairly long - if anyone wants more insight feel free to let me know.

First I declared all my variables as Public

Then I defined/set each variable

Lastly I set a new variable "SelectRanges" as the Union between the two other FormulaRanges

Public r As Long
Public c As Long
Public d As Long
Public FormulaRange3 As Range
Public FormulaRange4 As Range
Public SelectRanges As Range

With Sheet8




  c = pvt.DataBodyRange.Columns.Count + 1

  d = 3

  r = .Cells(.Rows.Count, 1).End(xlUp).Row

Set FormulaRange3 = .Range(.Cells(d, c + 2), .Cells(r - 1, c + 2))
    FormulaRange3.NumberFormat = "0"
    Set FormulaRange4 = .Range(.Cells(d, c + c + 2), .Cells(r - 1, c + c + 2))
    FormulaRange4.NumberFormat = "0"
    Set SelectRanges = Union(FormulaRange3, FormulaRange4)

I believe that if you run git branch --all from Bash that the list of remote and local branches you see will reflect what your local Git "knows" about at the time you run the command. Because your Git is always up to date with regard to the local branches in your system, the list of local branches will always be accurate.

However, for remote branches this need not be the case. Your local Git only knows about remote branches which it has seen in the last fetch (or pull). So it is possible that you might run git branch --all and not see a new remote branch which appeared after the last time you fetched or pulled.

To ensure that your local and remote branch list be up to date you can do a git fetch before running git branch --all.

For further information, the "remote" branches which appear when you run git branch --all are not really remote at all; they are actually local. For example, suppose there be a branch on the remote called feature which you have pulled at least once into your local Git. You will see origin/feature listed as a branch when you run git branch --all. But this branch is actually a local Git branch. When you do git fetch origin, this tracking branch gets updated with any new changes from the remote. This is why your local state can get stale, because there may be new remote branches, or your tracking branches can become stale.

I would prefer storing keys and values on separate arrays. This i often more practical. Structures of arrays are perfect replacement to array of structures. As most of the time you have to process only a subset of your data (in this cases keys or values, operation only with only one of the two arrays would be more efficient than operating with half of the two arrays together.

But in case this way is not possible, I would suggest to use arrays sorted by column instead of by row. In this way you would have the same benefit as having two arrays, but packed only in one.

import numpy as np
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}

names = 0
values = 1
array = np.empty(shape=(2, len(result)), dtype=float)
array[names] = result.keys()
array[values] = result.values()

But my favorite is this (simpler):

import numpy as np
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}

arrays = {'names': np.array(result.keys(), dtype=float),
          'values': np.array(result.values(), dtype=float)}

The FFT output coefficients (for complex input of size N) are from 0 to N - 1 grouped as [LOW,MID,HI,HI,MID,LOW] frequency.

I would consider that the element at k has the same frequency as the element at N-k since for real data, FFT[N-k] = complex conjugate of FFT[k].

The order of scanning from LOW to HIGH frequency is

0,

 1,
 N-1,

 2,
 N-2

 ...

 [N/2] - 1,
 N - ([N/2] - 1) = [N/2]+1,

 [N/2]

There are [N/2]+1 groups of frequency from index i = 0 to [N/2], each having the frequency = i * SamplingFrequency / N

So the frequency at bin FFT[k] is:

if k <= [N/2] then k * SamplingFrequency / N
if k >= [N/2] then (N-k) * SamplingFrequency / N

Assuming you're on Windows (if so you should tag your question as such!), on this MSDN page you can find the source for a simple, useful HRTimer C++ class that wraps the needed system calls to do something very close to what you require (it would be easy to add a GetTicks() method to it, in particular, to do exactly what you require).

On non-Windows platforms, there's no QueryPerformanceCounter function, so the solution won't be directly portable. However, if you do wrap it in a class such as the above-mentioned HRTimer, it will be easier to change the class's implementation to use what the current platform is indeed able to offer (maybe via Boost or whatever!).

Since favorites is an array, you just need to splice it off and save the document.

var mongoose = require('mongoose'),
    Schema = mongoose.Schema;

var favorite = new Schema({
    cn: String,
    favorites: Array
});

module.exports = mongoose.model('Favorite', favorite);

exports.deleteFavorite = function (req, res, next) {
    if (req.params.callback !== null) {
        res.contentType = 'application/javascript';
    }
    // Changed to findOne instead of find to get a single document with the favorites.
    Favorite.findOne({cn: req.params.name}, function (error, doc) {
        if (error) {
            res.send(null, 500);
        } else if (doc) {
            var records = {'records': doc};
            // find the delete uid in the favorites array
            var idx = doc.favorites ? doc.favorites.indexOf(req.params.deleteUid) : -1;
            // is it valid?
            if (idx !== -1) {
                // remove it from the array.
                doc.favorites.splice(idx, 1);
                // save the doc
                doc.save(function(error) {
                    if (error) {
                        console.log(error);
                        res.send(null, 500);
                    } else {
                        // send the records
                        res.send(records);
                    }
                });
                // stop here, otherwise 404
                return;
            }
        }
        // send 404 not found
        res.send(null, 404);
    });

You can delete column on i index like this:

df.drop(df.columns[i], axis=1)

It could work strange, if you have duplicate names in columns, so to do this you can rename column you want to delete column by new name. Or you can reassign DataFrame like this:

df = df.iloc[:, [j for j, c in enumerate(df.columns) if j != i]]

This gets you X and X' as variant arrays you can pass to another function.

Dim X() As Variant
Dim XT() As Variant
X = ActiveSheet.Range("InRng").Value2
XT = Application.Transpose(X)

To have the transposed values as a range, you have to pass it via a worksheet as in this answer. Without seeing how your covariance function works it's hard to see what you need.

Let's say we have a table with a column time and you want the last 5 entries, but you want them returned to you in asc order, not desc, this is how you do it:

select * from ( select * from `table` order by `time` desc limit 5 ) t order by `time` asc

On Ubuntu 18.04, I ran into this issue because the apt package for wheel does not include the wheel command. I think pip tries to import the wheel python package, and if that succeeds assumes that the wheel command is also available. Ubuntu breaks that assumption.

The apt python3 code package is named python3-wheel. This is installed automatically because python3-pip recommends it.

The apt python3 wheel command package is named python-wheel-common. Installing this too fixes the "failed building wheel" errors for me.

Images are not recommended since they may appear pixelated on some devices (Apple devices with Retina display) or when zoomed in. With a character, your list looks awesome everytime.

Here is the best solution I've found so far. It works great and it's cross-browser (IE 8+).

ul {
    list-style: none;
    padding-left: 1.2em;
    text-indent: -1.2em;
}

li:before {
    content: "?";
    display: block;
    float: left;
    width: 1.2em;
    color: #ff0000;
}

The important thing is to have the character in a floating block with a fixed width so that the text remains aligned if it's too long to fit on a single line. 1.2em is the width you want for your character, change it for your needs. Don't forget to reset padding and margin for ul and li elements.

EDIT: Be aware that the "1.2em" size may vary if you use a different font in ul and li:before. It's safer to use pixels.

LOAD DATA INFILE '/home/userlap/data2/worldcitiespop.txt' INTO TABLE cc FIELDS TERMINATED BY ','LINES TERMINATED BY '\r \n' IGNORE 1 LINES;

• IGNORE 1 LINES to skip over an initial header line containing column names
• FIELDS TERMINATED BY ',' is to read the comma-delimited file
• If you have generated the text file on a Windows system, you might have to use LINES TERMINATED BY '\r\n' to read the file properly, because Windows programs typically use two characters as a line terminator. Some programs, such as WordPad, might use \r as a line terminator when writing files. To read such files, use LINES TERMINATED BY '\r'.

public void setSecurity(int security){ this.security = security; }

    private enum Security {
            low,
            high
    }

With this you can simply call

yourObject.security() 

and it returns high/low as String, in this example

<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

works for me from Pardeep Jain

The solution provided by Emanuele worked for me. I could see the report when I accessed it directly from the server but when I used a ReportViewer control on my aspx page, I was unable to see the report. Upon inspecting the rendered HTML, I found a div by the id "ReportViewerGeneral_ctl09" (ReportViewerGeneral is the server id of the report viewer control) which had it's overflow property set to auto.

<div id="ReportViewerGeneral_ctl09" style="height: 100%; width: 100%; overflow: auto; position: relative; ">...</div>

I used the procedure explained by Emanuele to change this to visible as follows:

function pageLoad() {
    var element = document.getElementById("ReportViewerGeneral_ctl09");

    if (element) {
        element.style.overflow = "visible";
    }
}

RouterModule.forRoot([
      { path: 'welcome', component: WelcomeComponent },
      { path: '', redirectTo: 'welcome', pathMatch: 'full' },
      { path: '**', component: 'pageNotFoundComponent' }
    ])

Case 1 pathMatch:'full': In this case, when app is launched on localhost:4200 (or some server) the default page will be welcome screen, since the url will be https://localhost:4200/

If https://localhost:4200/gibberish this will redirect to pageNotFound screen because of path:'**' wildcard

Case 2 pathMatch:'prefix':

If the routes have { path: '', redirectTo: 'welcome', pathMatch: 'prefix' }, now this will never reach the wildcard route since every url would match path:'' defined.

I just put them in their own file and export it for node and webpack:

// lodash-cherries.js
module.exports = {
  defaults: require('lodash/defaults'),
  isNil: require('lodash/isNil'),
  isObject: require('lodash/isObject'),
  isArray: require('lodash/isArray'),
  isFunction: require('lodash/isFunction'),
  isInteger: require('lodash/isInteger'),
  isBoolean: require('lodash/isBoolean'),
  keys: require('lodash/keys'),
  set: require('lodash/set'),
  get: require('lodash/get'),
}

Assuming that by "string" you're talking about std::string in C++, you might have a look at the Tokenizer package in Boost.

Remove [selected] from option tag:

<option *ngFor="let opt of question.options" [value]="opt.key">
  {{opt.selected+opt.value}}
</option>

And in your form builder add:

key: this.question.options.filter(val => val.selected === true).map(data => data.key)

Use repr

>>> string = "abcd\n"
>>> print(repr(string))
'abcd\n'

For example if you want to repeat a word called "HELP" for 1000 times the following is the best way.

word = ['HELP']
repeat = 1000 * word

Then you will get the list of 1000 words and make that into a data frame if you want by using following command

word_data =pd.DataFrame(repeat)
word_data.columns = ['list_of_words'] #To change the column name 

If you installed MySQL from brew it really does only listen on the local interface by default. To fix that you need to edit /usr/local/etc/my.cnf and change the bind-address from 127.0.0.1 to *.

Then run brew services restart mysql.

Adding to the top voted answer and many ones above stressing the "more generic, better", I would like to dig a little bit more.

Map is the structure contract while HashMap is an implementation providing its own methods to deal with different real problems: how to calculate index, what is the capacity and how to increment it, how to insert, how to keep the index unique, etc.

Let's look into the source code:

In Map we have the method of containsKey(Object key):

boolean containsKey(Object key);

JavaDoc:

boolean java.util.Map.containsValue(Object value)

Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.

Parameters:value

value whose presence in this map is to betested

Returns:true

if this map maps one or more keys to the specified

valueThrows:

ClassCastException - if the value is of an inappropriate type for this map (optional)

NullPointerException - if the specified value is null and this map does not permit null values (optional)

It requires its implementations to implement it, but the "how to" is at its freedom, only to ensure it returns correct.

In HashMap:

public boolean containsKey(Object key) {
    return getNode(hash(key), key) != null;
}

It turns out that HashMap uses hashcode to test if this map contains the key. So it has the benefit of hash algorithm.

Pay attention to your dependency scope I was having the issue where when I invoke clean compile via Intellij, the pom would get downloaded, but the jar would not. There was a xxx.jar.lastUpdated file created. Then realized that the dependency scope was test, but I was triggering the compile. I deleted the repos, and triggered the mvn test, and issue was resolved.

According to my knowledge we should use ng-change with the select option and in textbox case we should use ng-blur.

if adding dependencies haven`t solved your problem, create WAR archive again. In my case, I used obsolete WAR file without security-web and security-conf jars

If you are testing this on your local WAMP you might need to set up the temporary folder for file uploads. You can do this in your PHP.ini file:

upload_tmp_dir = "c:\mypath\mytempfolder\"

You will need to grant permissions on the folder to allow the upload to take place - the permission you need to grant vary based on your operating system.

after research i found solution with short code. first of all create a public instance on fragment and just remove your fragment on onSaveInstanceState if fragment not recreating on orientation change.

 @Override
public void onSaveInstanceState(Bundle outState) {
    if (null != mCalFragment) {
        FragmentTransaction bt = getChildFragmentManager().beginTransaction();
        bt.remove(mFragment);
        bt.commit();
    }
    super.onSaveInstanceState(outState);
}

$('#div1').attr('class')

will return a string of the classes. Turn it into an array of class names

var classNames = $('#div1').attr('class').split(' ');

You don't need remove, just add again.

For anyone wondering about the difference between -1.#IND00 and -1.#IND (which the question specifically asked, and none of the answers address):

-1.#IND00

This specifically means a non-zero number divided by zero, e.g. 3.14 / 0 (source)

-1.#IND (a synonym for NaN)

This means one of four things (see wiki from source):

1) sqrt or log of a negative number

2) operations where both variables are 0 or infinity, e.g. 0 / 0

3) operations where at least one variable is already NaN, e.g. NaN * 5

4) out of range trig, e.g. arcsin(2)

First the facts, neither is better. As you already mentioned, Tomcat provides a servlet container that supports the Servlet specification (Tomcat 7 supports Servlet 3.0). JBoss AS, a 'complete' application server supports Java EE 6 (including Servlet 3.0) in its current version.

Tomcat is fairly lightweight and in case you need certain Java EE features beyond the Servlet API, you can easily enhance Tomcat by providing the required libraries as part of your application. For example, if you need JPA features you can include Hibernate or OpenEJB and JPA works nearly out of the box.

How to decide whether to use Tomcat or a full stack Java EE application server:

When starting your project you should have an idea what it requires. If you're in a large enterprise environment JBoss (or any other Java EE server) might be the right choice as it provides built-in support for e.g:

1. JMS messaging for asynchronous integration
2. Web Services engine (JAX-WS and/or JAX-RS)
3. Management capabilities like JMX and a scripted administration interface
4. Advanced security, e.g. out-of-the-box integration with 3rd party directories
5. EAR file instead of "only" WAR file support
6. all the other "great" Java EE features I can't remember :-)

In my opinion Tomcat is a very good fit if it comes to web centric, user facing applications. If backend integration comes into play, a Java EE application server should be (at least) considered. Last but not least, migrating a WAR developed for Tomcat to JBoss should be a 1 day excercise.

Second, you should also take the usage inside your environment into account. In case your organization already runs say 1,000 JBoss instances, you might always go with that regardless of your concrete requirements (consider aspects like cost for operations or upskilling). Of course, this applies vice versa.

Using "kill -9 [PID]" or "killall -9 node" worked for me where "kill -2 [PID]" did not work.

To answer also to the comment by @MLT, there is an alternative to the standard cases environment, not too sophisticated really, with both lines numbered. This code:

\documentclass{article}
\usepackage{amsmath}
\usepackage{cases}

\begin{document}

\begin{numcases}{f(x)=}
  1, & if $x<0$\\
  0, & otherwise
\end{numcases}

\end{document}

produces

Notice that here, math must be delimited by \(...\) or $...$, at least on the right of & in each line (reference).

Use DateDiff for this:

I tried the custom ForkJoinPool as follows to adjust the pool size:

private static Set<String> ThreadNameSet = new HashSet<>();
private static Callable<Long> getSum() {
    List<Long> aList = LongStream.rangeClosed(0, 10_000_000).boxed().collect(Collectors.toList());
    return () -> aList.parallelStream()
            .peek((i) -> {
                String threadName = Thread.currentThread().getName();
                ThreadNameSet.add(threadName);
            })
            .reduce(0L, Long::sum);
}

private static void testForkJoinPool() {
    final int parallelism = 10;

    ForkJoinPool forkJoinPool = null;
    Long result = 0L;
    try {
        forkJoinPool = new ForkJoinPool(parallelism);
        result = forkJoinPool.submit(getSum()).get(); //this makes it an overall blocking call

    } catch (InterruptedException | ExecutionException e) {
        e.printStackTrace();
    } finally {
        if (forkJoinPool != null) {
            forkJoinPool.shutdown(); //always remember to shutdown the pool
        }
    }
    out.println(result);
    out.println(ThreadNameSet);
}

Here is the output saying the pool is using more threads than the default 4.

50000005000000
[ForkJoinPool-1-worker-8, ForkJoinPool-1-worker-9, ForkJoinPool-1-worker-6, ForkJoinPool-1-worker-11, ForkJoinPool-1-worker-10, ForkJoinPool-1-worker-1, ForkJoinPool-1-worker-15, ForkJoinPool-1-worker-13, ForkJoinPool-1-worker-4, ForkJoinPool-1-worker-2]

But actually there is a weirdo, when I tried to achieve the same result using ThreadPoolExecutor as follows:

BlockingDeque blockingDeque = new LinkedBlockingDeque(1000);
ThreadPoolExecutor fixedSizePool = new ThreadPoolExecutor(10, 20, 60, TimeUnit.SECONDS, blockingDeque, new MyThreadFactory("my-thread"));

but I failed.

It will only start the parallelStream in a new thread and then everything else is just the same, which again proves that the parallelStream will use the ForkJoinPool to start its child threads.

Ive modifiet Lukas Knuth's solution a little:

1) There's no need to subclass the webview,

2) the code will crash during bytecode verification on some Android 1.6 devices if you don't put nonexistant methods in seperate classes

3) Zoom controls will still appear if the user scrolls up/down a page. I simply set the zoom controller container to visibility GONE

  wv.getSettings().setSupportZoom(true);
  wv.getSettings().setBuiltInZoomControls(true);
  if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
    // Use the API 11+ calls to disable the controls
    // Use a seperate class to obtain 1.6 compatibility
    new Runnable() {
      public void run() {
        wv.getSettings().setDisplayZoomControls(false);
      }
    }.run();
  } else {
    final ZoomButtonsController zoom_controll =
        (ZoomButtonsController) wv.getClass().getMethod("getZoomButtonsController").invoke(wv, null);
    zoom_controll.getContainer().setVisibility(View.GONE);
  }

There is no reflection in C++. True. But if the compiler can't provide you the metadata you need, you can provide it yourself.

Let's start by making a property struct:

template<typename Class, typename T>
struct PropertyImpl {
    constexpr PropertyImpl(T Class::*aMember, const char* aName) : member{aMember}, name{aName} {}

    using Type = T;

    T Class::*member;
    const char* name;
};

template<typename Class, typename T>
constexpr auto property(T Class::*member, const char* name) {
    return PropertyImpl<Class, T>{member, name};
}

Of course, you also can have a property that takes a setter and getter instead of a pointer to member, and maybe read only properties for calculated value you'd like to serialize. If you use C++17, you can extend it further to make a property that works with lambdas.

Ok, now we have the building block of our compile-time introspection system.

Now in your class Dog, add your metadata:

struct Dog {
    std::string barkType;
    std::string color;
    int weight = 0;

    bool operator==(const Dog& rhs) const {
        return std::tie(barkType, color, weight) == std::tie(rhs.barkType, rhs.color, rhs.weight);
    }

    constexpr static auto properties = std::make_tuple(
        property(&Dog::barkType, "barkType"),
        property(&Dog::color, "color"),
        property(&Dog::weight, "weight")
    );
};

We will need to iterate on that list. To iterate on a tuple, there are many ways, but my preferred one is this:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    using unpack_t = int[];
    (void)unpack_t{(static_cast<void>(f(std::integral_constant<T, S>{})), 0)..., 0};
}

If C++17 fold expressions are available in your compiler, then for_sequence can be simplified to:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    (static_cast<void>(f(std::integral_constant<T, S>{})), ...);
}

This will call a function for each constant in the integer sequence.

If this method don't work or gives trouble to your compiler, you can always use the array expansion trick.

Now that you have the desired metadata and tools, you can iterate through the properties to unserialize:

// unserialize function
template<typename T>
T fromJson(const Json::Value& data) {
    T object;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // get the type of the property
        using Type = typename decltype(property)::Type;

        // set the value to the member
        // you can also replace `asAny` by `fromJson` to recursively serialize
        object.*(property.member) = Json::asAny<Type>(data[property.name]);
    });

    return object;
}

And for serialize:

template<typename T>
Json::Value toJson(const T& object) {
    Json::Value data;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // set the value to the member
        data[property.name] = object.*(property.member);
    });

    return data;
}

If you want recursive serialization and unserialization, you can replace asAny by fromJson.

Now you can use your functions like this:

Dog dog;

dog.color = "green";
dog.barkType = "whaf";
dog.weight = 30;

Json::Value jsonDog = toJson(dog); // produces {"color":"green", "barkType":"whaf", "weight": 30}
auto dog2 = fromJson<Dog>(jsonDog);

std::cout << std::boolalpha << (dog == dog2) << std::endl; // pass the test, both dog are equal!

Done! No need for run-time reflection, just some C++14 goodness!

This code could benefit from some improvement, and could of course work with C++11 with some ajustements.

Note that one would need to write the asAny function. It's just a function that takes a Json::Value and call the right as... function, or another fromJson.

Here's a complete, working example made from the various code snippet of this answer. Feel free to use it.

As mentionned in the comments, this code won't work with msvc. Please refer to this question if you want a compatible code: Pointer to member: works in GCC but not in VS2015

If your hardware supports it try using Java RdRand Utility of which I'm the author.

Its based on Intel's RDRAND instruction and is about 10 times faster than SecureRandom and no bandwidth issues for large volume implementation.

Note that this implementation only works on those CPU's that provide the instruction (i.e. when the rdrand processor flag is set). You need to explicitly instantiate it through the RdRandRandom() constructor; no specific Provider has been implemented.

Use String.Replace() if you just want to replace the dots from string. Alternative would be to use Pattern-Matcher with StringBuilder, this gives you more flexibility as you can find groups that are between dots. If using the latter, i would recommend that you ignore empty entries with "\\.+".

public static int count(String str, String regex) {
    int i = 0;
    Pattern p = Pattern.compile(regex);
    Matcher m = p.matcher(str);
    while (m.find()) {
        m.group();
        i++;
    }
    return i;
}

public static void main(String[] args) {
    int i = 0, j = 0, k = 0;
    String str = "-.-..-...-.-.--..-k....k...k..k.k-.-";

    // this will just remove dots
    System.out.println(str.replaceAll("\\.", ""));
    // this will just remove sequences of ".." dots
    System.out.println(str.replaceAll("\\.{2}", ""));
    // this will just remove sequences of dots, and gets
    // multiple of dots as 1
    System.out.println(str.replaceAll("\\.+", ""));

    /* for this to be more obvious, consider following */
    System.out.println(count(str, "\\."));
    System.out.println(count(str, "\\.{2}"));
    System.out.println(count(str, "\\.+"));
}

The output will be:

--------kkkkk--
-.--.-.-.---kk.kk.k-.-

If you are using security annotation from the SensioFrameworkExtraBundle, you can use a few expressions (that are defined in \Symfony\Component\Security\Core\Authorization\ExpressionLanguageProvider):

• @Security("is_authenticated()"): to check that the user is authed and not anonymous
• @Security("is_anonymous()"): to check if the current user is the anonymous user
• @Security("is_fully_authenticated()"): equivalent to is_granted('IS_AUTHENTICATED_FULLY')
• @Security("is_remember_me()"): equivalent to is_granted('IS_AUTHENTICATED_REMEMBERED')

Note that reversing the whole string (either with the rbegin()/rend() range constructor or with std::reverse) and comparing it with the input would perform unnecessary work.

It's sufficient to compare the first half of the string with the latter half, in reverse:

#include <string>
#include <algorithm>
#include <iostream>
int main()
{
    std::string s;
    std::cin >> s;
    if( equal(s.begin(), s.begin() + s.size()/2, s.rbegin()) )
        std::cout << "is a palindrome.\n";
    else
        std::cout << "is NOT a palindrome.\n";
}

Or did you want to just see if a column only has NULL values (and, thus, is probably unused)?

Further clarification of the question might help.

EDIT: Ok.. here's some really rough code to get you going...

SET NOCOUNT ON
DECLARE @TableName Varchar(100)
SET @TableName='YourTableName'
CREATE TABLE #NullColumns (ColumnName Varchar(100), OnlyNulls BIT)
INSERT INTO #NullColumns (ColumnName, OnlyNulls) SELECT c.name, 0 FROM syscolumns c INNER JOIN sysobjects o ON c.id = o.id AND o.name = @TableName AND o.xtype = 'U'
DECLARE @DynamicSQL AS Nvarchar(2000)
DECLARE @ColumnName Varchar(100)
DECLARE @RC INT
    SELECT TOP 1 @ColumnName = ColumnName FROM #NullColumns WHERE OnlyNulls=0
    WHILE @@ROWCOUNT > 0
    BEGIN
        SET @RC=0
        SET @DynamicSQL = 'SELECT TOP 1 1 As HasNonNulls FROM ' + @TableName + ' (nolock) WHERE ''' + @ColumnName + ''' IS NOT NULL'
        EXEC sp_executesql @DynamicSQL
        set @RC=@@rowcount
        IF @RC=1
        BEGIN
            SET @DynamicSQL = 'UPDATE #NullColumns SET OnlyNulls=1 WHERE ColumnName=''' + @ColumnName + ''''
            EXEC sp_executesql @DynamicSQL
        END
        ELSE
        BEGIN

            EXEC sp_executesql @DynamicSQL
        END
    SELECT TOP 1 @ColumnName = ColumnName FROM #NullColumns WHERE OnlyNulls=0
    END

SELECT * FROM #NullColumns

DROP TABLE #NullColumns

As suggested here.

If you have a dataset named daily_data:

daily_data<-daily_data[order(as.Date(daily_data$date, format="%d/%m/%Y")),] 

This will output the number of lines that contain your search string.

grep -c "echo" FILE

This won't, however, count the number of occurrences in the file (ie, if you have echo multiple times on one line).

edit:

After playing around a bit, you could get the number of occurrences using this dirty little bit of code:

sed 's/echo/echo\n/g' FILE | grep -c "echo"

This basically adds a newline following every instance of echo so they're each on their own line, allowing grep to count those lines. You can refine the regex if you only want the word "echo", as opposed to "echoing", for example.

Put file inside while True like so

while True:
     f = open('torecv.png','wb')
     c, addr = s.accept()     # Establish connection with client.
     print 'Got connection from', addr
     print "Receiving..."
     l = c.recv(1024)
     while (l):
         print "Receiving..."
         f.write(l)
         l = c.recv(1024)
     f.close()
     print "Done Receiving"
     c.send('Thank you for connecting')
     c.close()   

You can get the query string in location.search, then you can split everything after the question mark:

var params = {};

Yes, Python does support Short-circuit evaluation, minimal evaluation, or McCarthy evaluation for Boolean operators. It is used to reduce the number of evaluations for computing the output of boolean expression. Example -

Base Functions

def a(x):
    print('a')
    return x

def b(x):
    print('b')
    return x 

AND

if(a(True) and b(True)):
    print(1,end='\n\n')

if(a(False) and b(True)):
    print(2,end='\n\n') 

AND-OUTPUT

a
b
1

a 

OR

if(a(True) or b(False)):
    print(3,end='\n\n')

if(a(False) or b(True)):
    print(4,end='\n\n') 

OR-OUTPUT

a

a
b

^{Rewrite of a now-deleted answer by VonC.}

Robert Gamble's succinct answer deals directly with the question. This one amplifies on some issues with filenames containing spaces.

See also: ${1:+"$@"} in /bin/sh

Basic thesis: "$@" is correct, and $* (unquoted) is almost always wrong. This is because "$@" works fine when arguments contain spaces, and works the same as $* when they don't. In some circumstances, "$*" is OK too, but "$@" usually (but not always) works in the same places. Unquoted, $@ and $* are equivalent (and almost always wrong).

So, what is the difference between $*, $@, "$*", and "$@"? They are all related to 'all the arguments to the shell', but they do different things. When unquoted, $* and $@ do the same thing. They treat each 'word' (sequence of non-whitespace) as a separate argument. The quoted forms are quite different, though: "$*" treats the argument list as a single space-separated string, whereas "$@" treats the arguments almost exactly as they were when specified on the command line. "$@" expands to nothing at all when there are no positional arguments; "$*" expands to an empty string — and yes, there's a difference, though it can be hard to perceive it. See more information below, after the introduction of the (non-standard) command al.

Secondary thesis: if you need to process arguments with spaces and then pass them on to other commands, then you sometimes need non-standard tools to assist. (Or you should use arrays, carefully: "${array[@]}" behaves analogously to "$@".)

Example:

    $ mkdir "my dir" anotherdir
    $ ls
    anotherdir      my dir
    $ cp /dev/null "my dir/my file"
    $ cp /dev/null "anotherdir/myfile"
    $ ls -Fltr
    total 0
    drwxr-xr-x   3 jleffler  staff  102 Nov  1 14:55 my dir/
    drwxr-xr-x   3 jleffler  staff  102 Nov  1 14:55 anotherdir/
    $ ls -Fltr *
    my dir:
    total 0
    -rw-r--r--   1 jleffler  staff  0 Nov  1 14:55 my file

    anotherdir:
    total 0
    -rw-r--r--   1 jleffler  staff  0 Nov  1 14:55 myfile
    $ ls -Fltr "./my dir" "./anotherdir"
    ./my dir:
    total 0
    -rw-r--r--   1 jleffler  staff  0 Nov  1 14:55 my file

    ./anotherdir:
    total 0
    -rw-r--r--   1 jleffler  staff  0 Nov  1 14:55 myfile
    $ var='"./my dir" "./anotherdir"' && echo $var
    "./my dir" "./anotherdir"
    $ ls -Fltr $var
    ls: "./anotherdir": No such file or directory
    ls: "./my: No such file or directory
    ls: dir": No such file or directory
    $

Why doesn't that work? It doesn't work because the shell processes quotes before it expands variables. So, to get the shell to pay attention to the quotes embedded in $var, you have to use eval:

    $ eval ls -Fltr $var
    ./my dir:
    total 0
    -rw-r--r--   1 jleffler  staff  0 Nov  1 14:55 my file

    ./anotherdir:
    total 0
    -rw-r--r--   1 jleffler  staff  0 Nov  1 14:55 myfile
    $ 

This gets really tricky when you have file names such as "He said, "Don't do this!"" (with quotes and double quotes and spaces).

    $ cp /dev/null "He said, \"Don't do this!\""
    $ ls
    He said, "Don't do this!"       anotherdir                      my dir
    $ ls -l
    total 0
    -rw-r--r--   1 jleffler  staff    0 Nov  1 15:54 He said, "Don't do this!"
    drwxr-xr-x   3 jleffler  staff  102 Nov  1 14:55 anotherdir
    drwxr-xr-x   3 jleffler  staff  102 Nov  1 14:55 my dir
    $ 

The shells (all of them) do not make it particularly easy to handle such stuff, so (funnily enough) many Unix programs do not do a good job of handling them. On Unix, a filename (single component) can contain any characters except slash and NUL '\0'. However, the shells strongly encourage no spaces or newlines or tabs anywhere in a path names. It is also why standard Unix file names do not contain spaces, etc.

When dealing with file names that may contain spaces and other troublesome characters, you have to be extremely careful, and I found long ago that I needed a program that is not standard on Unix. I call it escape (version 1.1 was dated 1989-08-23T16:01:45Z).

Here is an example of escape in use - with the SCCS control system. It is a cover script that does both a delta (think check-in) and a get (think check-out). Various arguments, especially -y (the reason why you made the change) would contain blanks and newlines. Note that the script dates from 1992, so it uses back-ticks instead of $(cmd ...) notation and does not use #!/bin/sh on the first line.

:   "@(#)$Id: delget.sh,v 1.8 1992/12/29 10:46:21 jl Exp $"
#
#   Delta and get files
#   Uses escape to allow for all weird combinations of quotes in arguments

case `basename $0 .sh` in
deledit)    eflag="-e";;
esac

sflag="-s"
for arg in "$@"
do
    case "$arg" in
    -r*)    gargs="$gargs `escape \"$arg\"`"
            dargs="$dargs `escape \"$arg\"`"
            ;;
    -e)     gargs="$gargs `escape \"$arg\"`"
            sflag=""
            eflag=""
            ;;
    -*)     dargs="$dargs `escape \"$arg\"`"
            ;;
    *)      gargs="$gargs `escape \"$arg\"`"
            dargs="$dargs `escape \"$arg\"`"
            ;;
    esac
done

eval delta "$dargs" && eval get $eflag $sflag "$gargs"

(I would probably not use escape quite so thoroughly these days - it is not needed with the -e argument, for example - but overall, this is one of my simpler scripts using escape.)

The escape program simply outputs its arguments, rather like echo does, but it ensures that the arguments are protected for use with eval (one level of eval; I do have a program which did remote shell execution, and that needed to escape the output of escape).

    $ escape $var
    '"./my' 'dir"' '"./anotherdir"'
    $ escape "$var"
    '"./my dir" "./anotherdir"'
    $ escape x y z
    x y z
    $ 

I have another program called al that lists its arguments one per line (and it is even more ancient: version 1.1 dated 1987-01-27T14:35:49). It is most useful when debugging scripts, as it can be plugged into a command line to see what arguments are actually passed to the command.

    $ echo "$var"
    "./my dir" "./anotherdir"
    $ al $var
    "./my
    dir"
    "./anotherdir"
    $ al "$var"
    "./my dir" "./anotherdir"
    $

[Added: And now to show the difference between the various "$@" notations, here is one more example:

$ cat xx.sh
set -x
al $@
al $*
al "$*"
al "$@"
$ sh xx.sh     *      */*
+ al He said, '"Don'\''t' do 'this!"' anotherdir my dir xx.sh anotherdir/myfile my dir/my file
He
said,
"Don't
do
this!"
anotherdir
my
dir
xx.sh
anotherdir/myfile
my
dir/my
file
+ al He said, '"Don'\''t' do 'this!"' anotherdir my dir xx.sh anotherdir/myfile my dir/my file
He
said,
"Don't
do
this!"
anotherdir
my
dir
xx.sh
anotherdir/myfile
my
dir/my
file
+ al 'He said, "Don'\''t do this!" anotherdir my dir xx.sh anotherdir/myfile my dir/my file'
He said, "Don't do this!" anotherdir my dir xx.sh anotherdir/myfile my dir/my file
+ al 'He said, "Don'\''t do this!"' anotherdir 'my dir' xx.sh anotherdir/myfile 'my dir/my file'
He said, "Don't do this!"
anotherdir
my dir
xx.sh
anotherdir/myfile
my dir/my file
$

Notice that nothing preserves the original blanks between the * and */* on the command line. Also, note that you can change the 'command line arguments' in the shell by using:

set -- -new -opt and "arg with space"

This sets 4 options, '-new', '-opt', 'and', and 'arg with space'.
]

Hmm, that's quite a long answer - perhaps exegesis is the better term. Source code for escape available on request (email to firstname dot lastname at gmail dot com). The source code for al is incredibly simple:

#include <stdio.h>
int main(int argc, char **argv)
{
    while (*++argv != 0)
        puts(*argv);
    return(0);
}

That's all. It is equivalent to the test.sh script that Robert Gamble showed, and could be written as a shell function (but shell functions didn't exist in the local version of Bourne shell when I first wrote al).

Also note that you can write al as a simple shell script:

[ $# != 0 ] && printf "%s\n" "$@"

The conditional is needed so that it produces no output when passed no arguments. The printf command will produce a blank line with only the format string argument, but the C program produces nothing.

Though the article is pretty old now, and though I understand that I'm not really very helpful, I think the work done here: http://www.pds.ewi.tudelft.nl/pubs/papers/cpe2005.pdf, would have been nice in mainstream Java.

You can do things like:

int a;
char b;
float c;
[a,b,c] = [3,'a',2.33];

or

[int,int,char] x = [1,2,'a'];

or

public [int,boolean] Find(int i)
{
  int idx = FindInArray(A,i);
  return [idx,idx>=0];
}

[idx, found] = Find(7);

Here tuples are:

• Defined as primitive types - no templates/generics
• Stack-allocated if declared locally
• Assigned using pattern-matching

This approach increases

• Performance
• Readability
• Expressiveness

I believe this might Help:

    System.out.println(Integer.toBinaryString(2 << 0));
    System.out.println(Integer.toBinaryString(2 << 1));
    System.out.println(Integer.toBinaryString(2 << 2));
    System.out.println(Integer.toBinaryString(2 << 3));
    System.out.println(Integer.toBinaryString(2 << 4));
    System.out.println(Integer.toBinaryString(2 << 5));

Result

The Safe Area Layout Guide helps avoid underlapping System UI elements when positioning content and controls.

The Safe Area is the area in between System UI elements which are Status Bar, Navigation Bar and Tool Bar or Tab Bar. So when you add a Status bar to your app, the Safe Area shrink. When you add a Navigation Bar to your app, the Safe Area shrinks again.

On the iPhone X, the Safe Area provides additional inset from the top and bottom screen edges in portrait even when no bar is shown. In landscape, the Safe Area is inset from the sides of the screens and the home indicator.

This is taken from Apple's video Designing for iPhone X where they also visualize how different elements affect the Safe Area.

The m000493 method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd:

string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));

string result = m000493(p0, "_p0lizei.");
//    result == "gaia^unplugged^Ta..."

with return m0001cd(builder3.ToString()); changed to return builder3.ToString();.

This is yet another way:

How is it not compatible with C#? Boolean.Parse and Boolean.TryParse is case insensitive and the parsing is done by comparing the value to Boolean.TrueString or Boolean.FalseString which are "True" and "False".

EDIT: When looking at the Boolean.ToString method in reflector it turns out that the strings are hard coded so the ToString method is as follows:

public override string ToString()
{
    if (!this)
    {
        return "False";
    }
    return "True";
}

You were almost there.

Remove protected $dates = ['license_expire']

and then change your LicenseExpire accessor to:

public function getLicenseExpireAttribute($date)
{
    return Carbon::parse($date);
}

This way it will return a Carbon instance no matter what. So for your form you would just have $employee->license_expire->format('Y-m-d') (or whatever format is required) and diffForHumans() should work on your home page as well.

Hope this helps!

Here is an in place replaceAll that will modify the passed in StringBuilder. I thought that I would post this as I was looking to do replaceAll with out creating a new String.

public static void replaceAll(StringBuilder sb, Pattern pattern, String replacement) {
    Matcher m = pattern.matcher(sb);
    while(m.find()) {
        sb.replace(m.start(), m.end(), replacement);
    }
}

I was shocked how simple the code to do this was (for some reason I thought changing the StringBuilder while using the matcher would throw of the group start/end but it does not).

This is probably faster than the other regex answers because the pattern is already compiled and your not creating a new String but I didn't do any benchmarking.

I don't think that it's possible for instance members to be removed before __del__ is called. My guess would be that the reason for your particular AttributeError is somewhere else (maybe you mistakenly remove self.file elsewhere).

However, as the others pointed out, you should avoid using __del__. The main reason for this is that instances with __del__ will not be garbage collected (they will only be freed when their refcount reaches 0). Therefore, if your instances are involved in circular references, they will live in memory for as long as the application run. (I may be mistaken about all this though, I'd have to read the gc docs again, but I'm rather sure it works like this).

RewriteRule ^properties$ /property_available.php/$1 [NC,QSA]

As said in Apache documentation :

The mod_rewrite module uses a rule-based rewriting engine, based on a PCRE regular-expression parser, to rewrite requested URLs on the fly.

So ^properties$ means Apache will only look for URL that has exact match with properties. You might want to try this code.

RewriteRule properties /property_available.php/$1 [NC,QSA]

So Apache will see the URL that has properties and rewrite it to /property_available.php/

Pyflakes does what you ask, it just checks the syntax. From the docs:

Pyflakes makes a simple promise: it will never complain about style, and it will try very, very hard to never emit false positives.

Pyflakes is also faster than Pylint or Pychecker. This is largely because Pyflakes only examines the syntax tree of each file individually.

To install and use:

$ pip install pyflakes
$ pyflakes yourPyFile.py

This demo is returning correctly for me in Chrome 14, FF3 and FF5 (with Firebug):

and changing the console.log to alert, I still get the desired output in IE6.

Clickatell is a popular SMS gateway. It works in 200+ countries.

Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.

The HTTP/S method is as simple as this:

http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here

The SMTP method consists of sending a plain-text e-mail to: [email protected], with the following body:

user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home

You can also test the gateway (incoming and outgoing) for free from your browser

jezrael's answer is good, but did not answer a question I had: Will getting the "sort" flag wrong mess up my data in any way? The answer is apparently "no", you are fine either way.

from pandas import DataFrame, concat

a = DataFrame([{'a':1,      'c':2,'d':3      }])
b = DataFrame([{'a':4,'b':5,      'd':6,'e':7}])

>>> concat([a,b],sort=False)
   a    c  d    b    e
0  1  2.0  3  NaN  NaN
0  4  NaN  6  5.0  7.0

>>> concat([a,b],sort=True)
   a    b    c  d    e
0  1  NaN  2.0  3  NaN
0  4  5.0  NaN  6  7.0

you can use #define round(a) (int) (a+0.5) as macro so whenever you write round(1.6) it returns 2 and whenever you write round(1.3) it return 1.

You can use the curl_error() function to detect if there was some error. For example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $your_url);
curl_setopt($ch, CURLOPT_FAILONERROR, true); // Required for HTTP error codes to be reported via our call to curl_error($ch)
//...
curl_exec($ch);
if (curl_errno($ch)) {
    $error_msg = curl_error($ch);
}
curl_close($ch);

if (isset($error_msg)) {
    // TODO - Handle cURL error accordingly
}

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

Stephen's answer is the one I'd use. For completeness, here's the DSU (decorate-sort-undecorate) pattern with list comprehensions:

decorated = [(tup[1], tup) for tup in data]
decorated.sort()
undecorated = [tup for second, tup in decorated]

Or, more tersely:

[b for a,b in sorted((tup[1], tup) for tup in data)]

As noted in the Python Sorting HowTo, this has been unnecessary since Python 2.4, when key functions became available.

As you said - there is one stand alone answer to this issue.

I had same issue after changing theme. Memory was set to 1024 before, so that's not the problem. Cache was cleared and there was nothing useful in error log.

In my case solution was different - old theme had custom homepage template... Switching it to standard one fixed it.

Expanding on zoul's answer:

If you want to setup Vim to use specific settings when editing a particular filetype, you'll want to use autocommands:

autocmd Filetype css setlocal tabstop=4

This will make it so that tabs are displayed as 4 spaces. Setting expandtab will cause Vim to actually insert spaces (the number of them being controlled by tabstop) when you press tab; you might want to use softtabstop to make backspace work properly (that is, reduce indentation when that's what would happen should tabs be used, rather than always delete one char at a time).

To make a fully educated decision as to how to set things up, you'll need to read Vim docs on tabstop, shiftwidth, softtabstop and expandtab. The most interesting bit is found under expandtab (:help 'expandtab):

There are four main ways to use tabs in Vim:

1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4 (or 3 or whatever you prefer) and use 'noexpandtab'. Then Vim will use a mix of tabs and spaces, but typing and will behave like a tab appears every 4 (or 3) characters.

2. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use 'expandtab'. This way you will always insert spaces. The formatting will never be messed up when 'tabstop' is changed.

3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a |modeline| to set these values when editing the file again. Only works when using Vim to edit the file.

4. Always set 'tabstop' and 'shiftwidth' to the same value, and 'noexpandtab'. This should then work (for initial indents only) for any tabstop setting that people use. It might be nice to have tabs after the first non-blank inserted as spaces if you do this though. Otherwise aligned comments will be wrong when 'tabstop' is changed.
