You can't use the naked domain of your-domain.com if it is not redirected to the www.your-domain.com. Heroku use the www.yourdomain.com which act here as a subdomain. So when you follow the default instruction to use your-domain.com then you will need to assign both of them.

We can actually assign only the naked domain without the www.your-domain.com. Use only your-domain.com when the domain's dns provider (NameServers) support ALIAS or ANAME for the @ Record to example.herokuapp.com without CNAME www.your-domain.com to it.

It will let you to point www.your-domain.com to other hosting separately (independent).

Well, people usually ask this question: Heroku or AWS when starting to deploy something.

My experiment of using both of Heroku & AWS, here is my quick review and comparison:

Heroku

• One command to deploy whatever your project types: Ruby on Rails, Nodejs
• So many 1-click to integrate plugins & third parties: It is super easy to start with something.
• Don't have auto-scaling; that means you need to scale up/down manually
• Cost is expensive, especially, when system needs more resources
• Free instance available
• The free instance goes to sleep if it is inactive.
• Data center: US & EU only
• CAN dive into/access to machine level by using Heroku run bash (Thanks, MJafar Mash for the advice) but it is kind of limited! You don't have full access!
• Don't need to know too much about DevOps

AWS - EC2

• This just like a machine with pre-config OS (or not), so you need to install software, library to make your website/service go online.
• Plugin & Library need to be integrated manually, or automation script (public script & written by you)
• Auto scaling & load balancer are the supported services, just learn how to config & integrate to your system
• Cost is quite cheap, depends on which services and number of hours you use it
• There are several free hours for T2.micro instances, but usually, you will pay few dollars every month (if still using T2.micro)
• Your free instance won't go to sleep, available 24/7 (because you may pay for it :) )
• Data center: around the world. Pick the region which is the best fit for you.
• Dive into machine level. So you can enjoy it
• Some knowledge about DevOps, but it is okay, Stackoverflow is helpful there!

AWS Elastic Beanstalk an alternative of Heroku, but cheaper

• Elastic Beanstalk was announced as a public beta from 2010; it helps we easier to work with deployment. For detail please go here

• Beanstalk is free, the cost you will pay will be for the services you use & number of hours of usage.

• I use Elastic Beanstalk for a long time, and I think it can be the replacement of Heroku and cheaper!

Summary

• Heroku: Easy at beginning, FREE instance, but expensive later
• AWS: Not easy, free hours available, kind of cheaper, Beanstalk should be concerned to use

So in my current system, I use Heroku for staging and Beanstalk for production!

for existing repository

type in terminal

$ heroku git:remote -a example

Do git status, this will show you what files have changed. Since you stated that you don't want to keep the changes you can do git checkout -- <file name> or git reset --hard to get rid of the changes.

For the most part, git will tell you what to do about changes. For example, your error message said to git stash your changes. This would be if you wanted to keep them. After pulling, you would then do git stash pop and your changes would be reapplied.

git status also has how to get rid of changes depending on if the file is staged for commit or not.

heroku logs -t shows us the live logs.

If this error pops up, its because there is no remote named Heroku. When you do a Heroku create, if the git remote doesn’t already exist, we automatically create one (assuming you are in a git repo). To view your remotes type in:

“git remote -v”. # For an app called ‘appname’ you will see the following:

$ git remote -v
heroku [email protected]:appname.git (fetch)
heroku [email protected]:appname.git (push)

If you see a remote for your app, you can just “git push master” and replace with the actual remote name.

If it’s missing, you can add the remote with the following command:

git remote add heroku [email protected]:appname.git

If you’ve already added a remote called Heroku, you may get an error like this:

fatal: remote heroku already exists.

so, then remove the existing remote and add it again with the above command:

git remote rm heroku

Hope this helps…

Don't know why, but only thing that worked for me was using asset_path instead of image_path, even though my images are under the assets/images/ directory:

Example:

app/assets/images/mypic.png

In Ruby:

asset_path('mypic.png')

In .scss:

url(asset-path('mypic.png'))

UPDATE:

Figured it out- turns out these asset helpers come from the sass-rails gem (which I had installed in my project).

OK, I don't think the official snippet mentioned by galuszkak should be used everywhere, we should concern the case that some bug may be triggered during the handler such as hello_world function. Whether the response is correct or uncorrect, the Access-Control-Allow-Origin header is what we should concern. So, thing is very simple, just like bellow:

@blueprint.after_request # blueprint can also be app~~
def after_request(response):
    header = response.headers
    header['Access-Control-Allow-Origin'] = '*'
    return response

That is all~~

Specify the buildpack while creating the app.

heroku create appname --buildpack heroku/python

This exception happened when I forgot to close the connections

I was going to leave this after this comment: Should I check in folder "node_modules" to Git when creating a Node.js app on Heroku?

But Stack Overflow was formatting it weirdly.

If you don't have identical machines and are checking in node_modules, do a .gitignore on the native extensions. Our .gitignore looks like:

# Ignore native extensions in the node_modules folder (things changed by npm rebuild)
node_modules/**/*.node
node_modules/**/*.o
node_modules/**/*.a
node_modules/**/*.mk
node_modules/**/*.gypi
node_modules/**/*.target
node_modules/**/.deps/
node_modules/**/build/Makefile
node_modules/**/**/build/Makefile

Test this by first checking everything in, and then have another developer do the following:

rm -rf node_modules
git checkout -- node_modules
npm rebuild
git status

Ensure that no files changed.

You can install the free New Relic add-on. It has an availability monitor feature that will ping your site twice per minute, thus preventing the dyno from idling.

More or less the same solution as Jesse but maybe more integrated to Heroku... And with a few perks (performance monitoring is just great).

Note: to all those saying it doesn't work: the important part in my answer is "availability monitor". Just installing the addon won't help. You also need to setup the availability monitoring with the URL of your heroku app.

If you are using the local server, run Django shell using python manage.py shell. It will take you to the Django python environment and you are good to go.

I had a similar heroku ssh error that I could not resolve.

As a workaround, I used the new heroku http-git feature (http transport for "heroku" remote instead of ssh). Details here: https://devcenter.heroku.com/articles/http-git

(Short version: if you have a project already setup the standard way, run heroku git:remote --http-init to change "heroku" remote to http.)

A good quick work around if you don't have time to fix/troubleshoot an ssh issue.

Here is what worked for me. The heroku site is not being added to your known hosts. Go to window-other- show view-git-git repositories. From there clone the repository. Once you clone it, delete the repository that was just created and then import it from the file menu. Do this since when you clone the repository, it does not add it to the explorer view. Now you should have the git repository and the explorer view.

Demi Magus answer worked for me until Rails 5.

On Apache2/Passenger/Ruby (2.4)/Rails (5.1.6), I had to put

export SECRET_KEY_BASE=GENERATED_CODE

from Demi Magus answer in /etc/apache2/envvars, cause /etc/profile seems to be ignored.

Source: https://www.phusionpassenger.com/library/indepth/environment_variables.html#apache

At of all the solution i have tried no one work as expected, i study heroku by default the .env File should maintain the convention PORT, the process.env.PORT, heroku by default will look for the Keyword PORT.

Cancel any renaming such as APP_PORT= instead use PORT= in your env file.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

1. View Remote URLs

   > git remote -v

    heroku  https://git.heroku.com/###########.git (fetch) < your Heroku Remote URL
    heroku  https://git.heroku.com/############.git (push)
    origin  https://github.com/#######/#####.git (fetch) < if you use GitHub then this is your GitHub remote URL
    origin  https://github.com/#######/#####.git (push)

2. Remove Heroku remote URL

   > git remote rm heroku

3. Set new Heroku URL

   > heroku git:remote -a ############

And you are done.

heroku ps:restart [web|worker] --app app_name

works for all processes declared in your Procfile. So if you have multiple web processes or worker processes, each labeled with a number, you can selectively restart one of them:

heroku ps:restart web.2 --app app_name
heroku ps:restart worker.3 --app app_name

The solution I posted on Dev and worked for most people using React:

https://medium.com/@uros.randelovic/causes-of-heroku-h10-app-crashed-error-and-how-to-solve-them-70495914d2a3?sk=1c51cf95e904f754a43a4b63a06b5503

npm install serve --s
"scripts": {
"dev": "react-scripts start",
"start": "serve -s build",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"heroku-postbuild": "npm run build"
}

Also check your database connection. I forgot to change my database connection from localhost and this crashed my app once it was pushed to heroku.

Another way to do it that's designed for django, but should work in most settings, is to use django-dotenv.

• Original - https://github.com/jacobian/django-dotenv
• More fully featured fork- https://github.com/tedtieken/django-dotenv-rw (I wrote this to be able to set my remote .env settings on webfaction from my local command line, heroku spoiled me)

My issue was I was instatiating the player completely from start but I used an iframe instead of a wrapper div.

You are not allowed to have a CNAME record for the domain, as the CNAME is an aliasing feature that covers all data types (regardless of whether the client looks for MX, NS or SOA records). CNAMEs also always refer to a new name, not an ip-address, so there are actually two errors in the single line

@                        IN CNAME   88.198.38.XXX

Changing that CNAME to an A record should make it work, provided the ip-address you use is the correct one for your Heroku app.

The only correct way in DNS to make a simple domain.com name work in the browser, is to point the domain to an IP-adress with an A record.

In my case i couldnt install a VueJS plugin and i had to:

Changing the ownership of files:

sudo chown -R $(whoami) ~/.npm
sudo chown -R $(whoami) /usr/local/lib
sudo chown -R $(whoami) /usr/local/bin

And then made sure to ahve latest npm:

npm install -g npm@latest

Then installed my plugin and in your case probably your command isntead.

Also note that if your using the git flow system and your feature branch might be called

feature/mobile_additions

and with a git remote called stagingtwo, then the command to push to heroku would be

git push stagingtwo feature/mobile_additions:master

I contacted Heroku support, and they confirmed that it is a bug with the latest gem (I am using heroku-2.26.2)

Charlie - we are aware of this issue with the 'heroku' gem and are working to fix it.

Here's the issue if you care to follow-along - https://github.com/heroku/heroku/issues/356

Downgrading to an earlier version of the 'heroku' gem should help. I've been using v2.25.0 for most of today without issue.

Downgrade with the following commands:

gem uninstall heroku

gem install heroku --version 2.25.0

If you already have multiple gems installed, you may be presented with:

Select gem to uninstall:
 1. heroku-2.25.0
 2. heroku-2.26.2
 3. All versions

Just uninstall #2 and rerun the command. Joy!

I'm the only person working on my app and only work on it from my desktop, so the possibility that I managed to get the heroku repository above dev didn't make sense. BUT! I recently had a Heroku support rep look into my heroku account for a cache issue involving gem installs and he had changed something that caused heroku to return the same error as the one listed above. A git pull heroku master was all it took. Then I found the reps minor change and reverted it myself.

To completely 'stop' your app you can scale the web dynos down to zero which effectively takes all your app http-processes offline.

$ heroku ps:scale web=0
Scaling web processes... done, now running 0

You would use the command Mechanical snail listed. Notice the uppercase O. Full command line to use could be:

wget www.examplesite.com/textfile.txt --output-document=newfile.txt

or

wget www.examplesite.com/textfile.txt -O newfile.txt

Hope that helps.

I rather prefer to:

@interface MyViewController : UIViewController
@property (nonatomic, retain) IBOutletCollection(UIView) NSArray *inputFields;
@end

In the NIB file I hook the textFields in the desired order into this inputFields array. After that I do a simple test for the index of the UITextField that reports that the user tapped return:

// for UITextField
-(BOOL)textFieldShouldReturn:(UITextField*)textField {
    NSUInteger index = [_inputFields indexOfObject:textField];
    index++;
    if (index < _inputFields.count) {
        UIView *v = [_inputFields objectAtIndex:index];
        [v becomeFirstResponder];
    }
    return NO;
}

// for UITextView
-(BOOL)textView:(UITextView*)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString*)text {
    if ([@"\n" isEqualToString:text]) {
        NSUInteger index = [_inputFields indexOfObject:textView];
        index++;
        if (index < _inputFields.count) {
            UIView *v = [_inputFields objectAtIndex:index];
            [v becomeFirstResponder];
        } else {
            [self.view endEditing:YES];
        }
        return NO;
    }
    return YES;
}

In some cases you may need to move the focus to the next field manually :

focusSearch(FOCUS_DOWN).requestFocus();

You might need this if, for example, you have a text field that opens a date picker on click, and you want the focus to automatically move to the next input field once a date is selected by the user and the picker closes. There's no way to handle this in XML, it has to be done programmatically.

Angular CLI provides all the commands you need in your app development. For your specific requirement, you can easily use ng g (ng generate) to get the work done.

ng g c directory/component-name will generate component-name component in the directory folder.

Following is a map of a few simple commands you can use in your application.

1. ng g c comp-name or ng generate component comp-name to create a component with the name 'comp-name'
2. ng g s serv-name or ng generate service serv-name to create a service with the name 'serv-name'
3. ng g m mod-name or ng generate module mod-name to create a module with the name 'mod-name'
4. ng g m mod-name --routing or ng generate module mod-name --routing to create a module with the name 'mod-name' with angular routing

Hope this helps!

Good Luck!

If you have numpy installed you can try:

data = numpy.asarray(im)

(I say "try" here, because it's unclear why getdata() isn't working for you, and I don't know whether asarray uses getdata, but it's worth a test.)

Download the version of Connector from https://dev.mysql.com/downloads/connector/c/6.0.html For my case I had installed 64 bit of connector and my python was 32 bit. So I had to copy MySQL from program files to Program Files(86)

I think you will need to edit the doxys file and set GENERATE_UML (something like that) to true. And you need to have dot/graphviz installed.

swift3

extension UIImage {
    func crop(rect: CGRect) -> UIImage? {
        var scaledRect = rect
        scaledRect.origin.x *= scale
        scaledRect.origin.y *= scale
        scaledRect.size.width *= scale
        scaledRect.size.height *= scale
        guard let imageRef: CGImage = cgImage?.cropping(to: scaledRect) else {
            return nil
        }
        return UIImage(cgImage: imageRef, scale: scale, orientation: imageOrientation)
    }
}

Just noting that if you wish to redirect both stderr and stdout to a file while you have noclobber set (i.e. set -o noclobber), you can use the code:

cmd >| file.txt 2>&1

More information about this can be seen at https://stackoverflow.com/a/876242.

Also this answer's @TuBui's question on the answer @BrDaHa provided above at Aug 9 '18 at 9:34.

I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.

Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Yay.

Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.

Create a Bower configuration file .bowerrc in the project root (as opposed to your home directory) with the content:

{
  "directory" : "public/components"
}

Run bower install again.

You might use Form tag with action attribute to submit the mailto.

Here is an example:

<form method="post" action="mailto:[email protected]" >
<input type="submit" value="Send Email" /> 
</form>

Try this.

SELECT * FROM la_schedule WHERE `start_date` > '2012-11-18';

You can access elements of parent window from within an iframe by using window.parent like this:

// using jquery    
window.parent.$("#element_id");

Which is the same as:

// pure javascript
window.parent.document.getElementById("element_id");

And if you have more than one nested iframes and you want to access the topmost iframe, then you can use window.top like this:

// using jquery
window.top.$("#element_id");

Which is the same as:

// pure javascript
window.top.document.getElementById("element_id");

Very simple way to do this---

In your Activity--

 TextView tv = (TextView) findViewById(R.id.site);
 tv.setText(Html.fromHtml("<a href=http://www.stackoverflow.com> STACK OVERFLOW "));
 tv.setMovementMethod(LinkMovementMethod.getInstance());

Then you will get just the Tag, not the whole link..

Hope it will help you...

if you want UTC try some of the gm functions:

import time
import calendar

date_time = '29.08.2011 11:05:02'
pattern = '%d.%m.%Y %H:%M:%S'
utc_epoch = calendar.timegm(time.strptime(date_time, pattern))
print utc_epoch

There are several methods of std::string for searching, but find is probably what you're looking for. If you mean a C-style string, then the equivalent is strchr. However, in either case, you can also use a for loop and check each character—the loop is essentially what these two wrap up.

Once you know how to find the next character given a starting position, you continually advance your search (i.e. use a loop), counting as you go.

Without jQuery:

document.getElementById('file').onchange = function(){

  var file = this.files[0];

  var reader = new FileReader();
  reader.onload = function(progressEvent){
    // Entire file
    console.log(this.result);

    // By lines
    var lines = this.result.split('\n');
    for(var line = 0; line < lines.length; line++){
      console.log(lines[line]);
    }
  };
  reader.readAsText(file);
};

HTML:

<input type="file" name="file" id="file">

Remember to put your javascript code after the file field is rendered.

What you'll see sometimes is the following:

class Abstract1( object ):
    """Some description that tells you it's abstract,
    often listing the methods you're expected to supply."""
    def aMethod( self ):
        raise NotImplementedError( "Should have implemented this" )

Because Python doesn't have (and doesn't need) a formal Interface contract, the Java-style distinction between abstraction and interface doesn't exist. If someone goes through the effort to define a formal interface, it will also be an abstract class. The only differences would be in the stated intent in the docstring.

And the difference between abstract and interface is a hairsplitting thing when you have duck typing.

Java uses interfaces because it doesn't have multiple inheritance.

Because Python has multiple inheritance, you may also see something like this

class SomeAbstraction( object ):
    pass # lots of stuff - but missing something

class Mixin1( object ):
    def something( self ):
        pass # one implementation

class Mixin2( object ):
    def something( self ):
        pass # another

class Concrete1( SomeAbstraction, Mixin1 ):
    pass

class Concrete2( SomeAbstraction, Mixin2 ):
    pass

This uses a kind of abstract superclass with mixins to create concrete subclasses that are disjoint.

I tested 2 set based randomization methods against RAND() by generating 100,000,000 rows with each. To level the field the output is a float between 0-1 to mimic RAND(). Most of the code is testing infrastructure so I summarize the algorithms here:

-- Try #1 used
(CAST(CRYPT_GEN_RANDOM(8) AS BIGINT)%500000000000000000+500000000000000000.0)/1000000000000000000 AS Val
-- Try #2 used
RAND(Checksum(NewId()))
-- and to have a baseline to compare output with I used
RAND() -- this required executing 100000000 separate insert statements

Using CRYPT_GEN_RANDOM was clearly the most random since there is only a .000000001% chance of seeing even 1 duplicate when plucking 10^8 numbers FROM a set of 10^18 numbers. IOW we should not have seen any duplicates and this had none! This set took 44 seconds to generate on my laptop.

RAND() alone is useless for set-based generation so generating the baseline for comparing randomness took over 6 hours and had to be restarted several times to finally get the right number of output rows. It also seems that the randomness leaves a lot to be desired although it's better than using checksum(newid()) to reseed each row.

In my case EXC_I386_GPFLT was caused by missing return value in the property getter. Like this:

    data.b = self.beta;

    return data; // this line was missing

Date object in js support comparison, set them same date for compare hh:mm:ss :

new Date ('1/1/1999 ' + '10:20:45') > new Date ('1/1/1999 ' + '5:10:10') 
> true

They should be pretty much the same. The difference isn't going to matter. I would go with sprintf since it requires less code.

Here is my code for get only date:

Calendar c=Calendar.getInstance();
DateFormat dm = new SimpleDateFormat("dd/MM/yyyy");
java.util.Date date = new java.util.Date();
System.out.println("current date is :    " + dm.format(date));

this will do the job easily to get the last part of the required URL

$requred_string= substr(strrchr($url, "/"), 1);

this will get you the string after first "/" from the right.

You can learn datetime formatting in sql server here

In Tomcat 7.0 Windows Service Installer Version.There is not catalina.bat in /bin . So you need open Tomcat7w.exe in /bin and add blow JVM argument

-XX:PermSize=256m -XX:MaxPermSize=512m

on Java Option in Java Tab, like this. You also add other options.

Another, if you use IntellijIDEA you need add JVM argument in Server Configurations,like this.

This helped me to get uri from Gallery and convert to a file for Multipart upload

File file = FileUtils.getFile(this, fileUri);

Edit: 3 years has passed since I answered this question and I guess a more modern solution is needed, although the current one does the thing :)

1.Flexbox

It's by far the shortest and most flexible. Apply display: flex; to the parent container and adjust the placement of its children by justify-content: space-between; like this:

.header {
    display: flex;
    justify-content: space-between;
}

Can be seen online here - http://jsfiddle.net/skip405/NfeVh/1073/

Note however that flexbox support is IE10 and newer. If you need to support IE 9 or older, use the following solution:

2.You can use the text-align: justify technique here.

.header {
    background: #ccc; 
    text-align: justify; 

    /* ie 7*/  
    *width: 100%;  
    *-ms-text-justify: distribute-all-lines;
    *text-justify: distribute-all-lines;
}
 .header:after{
    content: '';
    display: inline-block;
    width: 100%;
    height: 0;
    font-size:0;
    line-height:0;
}

h1 {
    display: inline-block;
    margin-top: 0.321em; 

    /* ie 7*/ 
    *display: inline;
    *zoom: 1;
    *text-align: left; 
}

.nav {
    display: inline-block;
    vertical-align: baseline; 

    /* ie 7*/
    *display: inline;
    *zoom:1;
    *text-align: right;
}

The working example can be seen here: http://jsfiddle.net/skip405/NfeVh/4/. This code works from IE7 and above

If inline-block elements in HTML are not separated with space, this solution won't work - see example http://jsfiddle.net/NfeVh/1408/ . This might be a case when you insert content with Javascript.

If we don't care about IE7 simply omit the star-hack properties. The working example using your markup is here - http://jsfiddle.net/skip405/NfeVh/5/. I just added the header:after part and justified the content.

In order to solve the issue of the extra space that is inserted with the after pseudo-element one can do a trick of setting the font-size to 0 for the parent element and resetting it back to say 14px for the child elements. The working example of this trick can be seen here: http://jsfiddle.net/skip405/NfeVh/326/

File myFile = new File(uri.toString());
myFile.getAbsolutePath()

should return u the correct path

EDIT

As @Tron suggested the working code is

File myFile = new File(uri.getPath());
myFile.getAbsolutePath()

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

Have you tried using the generic DeserializeObject method?

JsonConvert.DeserializeObject<MyAccount>(myjsondata);

Any missing fields in the JSON data should simply be left NULL.

UPDATE:

If the JSON string is an array, try this:

var jarray = JsonConvert.DeserializeObject<List<MyAccount>>(myjsondata);

jarray should then be a List<MyAccount>.

ANOTHER UPDATE:

The exception you're getting isn't consistent with an array of objects- I think the serializer is having problems with your Dictionary-typed accountstatusmodifiedby property.

Try excluding the accountstatusmodifiedby property from the serialization and see if that helps. If it does, you may need to represent that property differently.

Cong Ma does a good job of explaining what __getitem__ is used for - but I want to give you an example which might be useful. Imagine a class which models a building. Within the data for the building it includes a number of attributes, including descriptions of the companies that occupy each floor :

Without using __getitem__ we would have a class like this :

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def occupy(self, floor_number, data):
          self._floors[floor_number] = data
     def get_floor_data(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1.occupy(0, 'Reception')
building1.occupy(1, 'ABC Corp')
building1.occupy(2, 'DEF Inc')
print( building1.get_floor_data(2) )

We could however use __getitem__ (and its counterpart __setitem__) to make the usage of the Building class 'nicer'.

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def __setitem__(self, floor_number, data):
          self._floors[floor_number] = data
     def __getitem__(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1[0] = 'Reception'
building1[1] = 'ABC Corp'
building1[2] = 'DEF Inc'
print( building1[2] )

Whether you use __setitem__ like this really depends on how you plan to abstract your data - in this case we have decided to treat a building as a container of floors (and you could also implement an iterator for the Building, and maybe even the ability to slice - i.e. get more than one floor's data at a time - it depends on what you need.

For Western Arabic numbers (0-9):

$words = preg_replace('/[0-9]+/', '', $words);

For all numerals including Western Arabic (e.g. Indian):

$words = '????';
$words = preg_replace('/\d+/u', '', $words);
var_dump($words); // string(0) ""

• \d+ matches multiple numerals.
• The modifier /u enables unicode string treatment. This modifier is important, otherwise the numerals would not match.

The simplest thing you can do is cherry picking a range. It does the same as the rebase --onto but is easier for the eyes :)

git cherry-pick quickfix1..quickfix2

    public boolean empty() {
    boolean isEmpty = true;
    int i = 0;
    for (int j = 0; j < array.length; j++) {
        if (array[j] != 0) {
            i++;
        }
    }
    if (i != 0) {
        isEmpty = false;
    }
    return isEmpty;
}

This is as close as I got to checking if an int array is empty. Although this will not work when the ints in the array are actually zero. It'll work for {1,2,3}, and it'll still return false if {2,0} but {0} will return true

I tried all suggested answers. I found out this is a hardware issue on Android N phone with studio 2.3 version. App launches fine on phones below version 7.

similar to @Anh Duy's answer, but it didnt work for me. i also needed the cursor to move to the end only when the user taps the edit text and still be able to select the position of the cursor afterwards, this is the only code that has worked for me

boolean textFocus = false; //define somewhere globally in the class

//in onFinishInflate() or somewhere
editText.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {

        editText.onTouchEvent(event);

        if(!textFocus) {
            editText.setSelection(editText.getText().length());
            textFocus = true;
        }

        return true;
    }
});

editText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        textFocus = false;
    }
});

The numbers generated by

=NORMINV(RAND(),10,7)

are uniformally distributed. If you want the numbers to be normally distributed, you will have to write a function I guess.

All the previous answers only provide a hard-coded location of where the first column ends and the second column starts. I would have expected that this is not required or even not wanted.

Recent CSS versions know about an attribute called columns which makes column based layouts super easy. For older browsers you need to include -moz-columns and -webkit-columns, too.

Here's a very simple example which creates up to three columns if each of them has at least 200 pixes width, otherwise less columns are used:

<html>
  <head>
    <title>CSS based columns</title>
  </head>
  <body>
    <h1>CSS based columns</h1>
    <ul style="columns: 3 200px; -moz-columns: 3 200px; -webkit-columns: 3 200px;">
      <li>Item one</li>
      <li>Item two</li>
      <li>Item three</li>
      <li>Item four</li>
      <li>Item five</li>
      <li>Item six</li>
      <li>Item eight</li>
      <li>Item nine</li>
      <li>Item ten</li>
      <li>Item eleven</li>
      <li>Item twelve</li>
      <li>Item thirteen</li>
    </ul>
  </body>
</html>

The right answer (using Python 2.7 and later, since check_output() was introduced then) is:

py2output = subprocess.check_output(['python','py2.py','-i', 'test.txt'])

To demonstrate, here are my two programs:

py2.py:

import sys
print sys.argv

py3.py:

import subprocess
py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'])
print('py2 said:', py2output)

Running it:

$ python3 py3.py
py2 said: b"['py2.py', '-i', 'test.txt']\n"

Here's what's wrong with each of your versions:

py2output = subprocess.check_output([str('python py2.py '),'-i', 'test.txt'])

First, str('python py2.py') is exactly the same thing as 'python py2.py'—you're taking a str, and calling str to convert it to an str. This makes the code harder to read, longer, and even slower, without adding any benefit.

More seriously, python py2.py can't be a single argument, unless you're actually trying to run a program named, say, /usr/bin/python\ py2.py. Which you're not; you're trying to run, say, /usr/bin/python with first argument py2.py. So, you need to make them separate elements in the list.

Your second version fixes that, but you're missing the ' before test.txt'. This should give you a SyntaxError, probably saying EOL while scanning string literal.

Meanwhile, I'm not sure how you found documentation but couldn't find any examples with arguments. The very first example is:

>>> subprocess.check_output(["echo", "Hello World!"])
b'Hello World!\n'

That calls the "echo" command with an additional argument, "Hello World!".

Also:

-i is a positional argument for argparse, test.txt is what the -i is

I'm pretty sure -i is not a positional argument, but an optional argument. Otherwise, the second half of the sentence makes no sense.

Maybe like this:

list('abcdefgh') # ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']

The following statement with FROM keyword is used to update multiple rows with a join

UPDATE users 
set users.DivisionId=divisions.DivisionId
from divisions join users on divisions.Name=users.Division

The following answer is not exactly optimal by any measure, but I needed something that maintains its position within the container whilst it stretches the inner div fully.

https://jsfiddle.net/fah5axm5/

$(function() {
    $(window).on('load resize', ppaFullWidth);

    function ppaFullWidth() {
        var $elements = $('[data-ppa-full-width="true"]');
        $.each( $elements, function( key, item ) {
            var $el = $(this);
            var $container = $el.closest('.container');
            var margin = parseInt($container.css('margin-left'), 10);
            var padding = parseInt($container.css('padding-left'), 10)
            var offset = margin + padding;

            $el.css({
                position: "relative",
                left: -offset,
                "box-sizing": "border-box",
                width: $(window).width(),
                "padding-left": offset + "px",
                "padding-right": offset + "px"
            });
        });
    }
});

Anyone arriving here who wants the quick answer to this problem. Replace the "Dropdown.prototype.toggle" function in your bootstrap.js (or dropdown.js) with the following:

  Dropdown.prototype.toggle = function (e) {
var $this = $(this)

if ($this.is('.disabled, :disabled')) return

var $parent  = getParent($this)
var isActive = $parent.hasClass('open')

clearMenus()

if (!isActive) {
    if ('ontouchstart' in document.documentElement && !$parent.closest('.navbar-nav').length) {
        // if mobile we use a backdrop because click events don't delegate
        $('<div class="dropdown-backdrop"/>').insertAfter($(this)).on('click', clearMenus)
    }

    var relatedTarget = { relatedTarget: this }
    $parent.trigger(e = $.Event('show.bs.dropdown', relatedTarget))

    if (e.isDefaultPrevented()) return

    $parent
      .toggleClass('open')
      .trigger('shown.bs.dropdown', relatedTarget)

    $this.focus()
}
else
{
    var href = $this.attr("href").trim();

    if (href != undefined && href != " javascript:;")
        window.location.href = href;
}

return false
  }

On the second click (ie: if the menu item has the class "open") it will first check if the href is undefined or set to "javascript:;" before sending you along your merry way.

Enjoy!

Here is a class that can be used to setup and run ordered tests independent of MS Ordered Tests framework for whatever reason--like not have to adjust mstest.exe arguments on a build machine, or mixing ordered with non-ordered in a class.

The original testing framework only sees the list of ordered tests as a single test so any init/cleanup like [TestInitalize()] Init() is only called before and after the entire set.

Usage:

        [TestMethod] // place only on the list--not the individuals
        public void OrderedStepsTest()
        {
            OrderedTest.Run(TestContext, new List<OrderedTest>
            {
                new OrderedTest ( T10_Reset_Database, false ),
                new OrderedTest ( T20_LoginUser1, false ),
                new OrderedTest ( T30_DoLoginUser1Task1, true ), // continue on failure
                new OrderedTest ( T40_DoLoginUser1Task2, true ), // continue on failure
                // ...
            });                
        }

You can bind to all of the radio buttons at once by name:

$('input[name=someRadioGroup]:radio').change(...);

MySQL provides a very cute solution :

REPLACE INTO `table` VALUES (5, 'John', 'Doe', SHA1('password'));

Very easy to use since you have declared a unique primary key (here with value 5).

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans

POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.

I got this error when I added a new developer account. I changed the Team under project name but I missed to update it under the Pods folder.

I solved it once I updated the new developer ID under the Teams option available under Pods-> Signing -> Team, the error was gone and the build succeeded.

Another possible solution. Count empty cells and subtract that value from the total number of cells

Sub Emptys()

Dim r As range
Dim totalCells As Integer

'My range To check'
Set r = ActiveSheet.range("A1:B5")

'Check for filled cells'
totalCells = r.Count- WorksheetFunction.CountBlank(r)


If totalCells = 0 Then
    MsgBox "Range is empty"
Else
    MsgBox "Range is not empty"
End If

End Sub

I wrote this post if anyone come across this question for PrestaShop, I don't know if it will work for Magento2. I solved enabling PHP extension intl for the PrestaShop installation by:

1. Open XAMPP Control Pane.
2. Stop the Apache server if it was started.
3. Then from Config button click on PHP (php.ini) item.

4. Php.ini will open in Notepad (or a default text editor), click Ctrl + F and search for ;extension=intl and remove the semicolon.

5. Then save and close Notepad and re-start the Apache server.

These steps for me solved the issue.

Note (2): I'm using XAMPP v3.2.3 and PrestaShop v1.7.5.1

Slightly similar to one of examples here, simplified from std::map usage perspective.

template<class KEY, class VALUE>
std::vector<KEY> getKeys(const std::map<KEY, VALUE>& map)
{
    std::vector<KEY> keys(map.size());
    for (const auto& it : map)
        keys.push_back(it.first);
    return keys;
}

Use like this:

auto keys = getKeys(yourMap);

AppMobi HTML5 SDK once promised access to native device functionality - including the camera - from an HTML5-based app, but is no longer Google-owned. Instead, try the HTML5-based answers in this post.

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

Since "$(this).parent().index();" and "$(this).parent('table').index();" don't work for me, I use this code instead:

$('td').click(function(){
   var row_index = $(this).closest("tr").index();
   var col_index = $(this).index();
});

There is no way to do this in the GitHub web application. I believe to only way to do this is in the command line using git mv <old name> <new name> or by using a Git client(like SourceTree).

Now that Firefox Quantum 57 is out with substantial — and potentially breaking — improvements to Gecko collectively known as Stylo or Quantum CSS, you may find yourself in a situation where you have to distinguish between legacy versions of Firefox and Firefox Quantum.

From my answer here:

You can use @supports with a calc(0s) expression in conjunction with @-moz-document to test for Stylo — Gecko does not support time values in calc() expressions but Stylo does:

@-moz-document url-prefix() {
  @supports (animation: calc(0s)) {
    /* Stylo */
  }
}

Here's a proof-of-concept:

_x000D_

_x000D_

body::before {_x000D_
  content: 'Not Fx';_x000D_
}_x000D_
_x000D_
@-moz-document url-prefix() {_x000D_
  body::before {_x000D_
    content: 'Fx legacy';_x000D_
  }_x000D_
_x000D_
  @supports (animation: calc(0s)) {_x000D_
    body::before {_x000D_
      content: 'Fx Quantum';_x000D_
    }_x000D_
  }_x000D_
}

_x000D_

_x000D_

_x000D_

Targeting legacy versions of Firefox is a little tricky — if you're only interested in versions that support @supports, which is Fx 22 and up, @supports not (animation: calc(0s)) is all you need:

@-moz-document url-prefix() {
  @supports not (animation: calc(0s)) {
    /* Gecko */
  }
}

... but if you need to support even older versions, you'll need to make use of the cascade, as demonstrated in the proof-of-concept above.

Asynchronous reading of stream combined with avoiding Wait with a timeout will solve the problem.

You can find a page explaining this here http://simplebasics.net/.net/process-waitforexit-with-a-timeout-will-not-be-able-to-collect-the-output-message/

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

One more alternative is to place one of the subviews inside of an HStack and place a Spacer() after it:

struct ContentView : View {
    var body: some View {
        VStack(alignment: .leading) {

            HStack {
                Text("Title")
                    .font(.title)
                    .background(Color.yellow)
                Spacer()
            }

            Text("Content")
                .lineLimit(nil)
                .font(.body)
                .background(Color.blue)

            Spacer()
            }

            .background(Color.red)
    }
}

resulting in :

The following line in your code creates a new array, copies all object references from genericItems into that new array, and assigns it to backupData:

this.backupData = this.genericItems.slice();

So while backupData and genericItems are different arrays, they contain the same exact object references.

You could bring in a library to do deep copying for you (as @LatinWarrior mentioned).

But if Item is not too complex, maybe you can add a clone method to it to deep clone the object yourself:

class Item {
  somePrimitiveType: string;
  someRefType: any = { someProperty: 0 };

  clone(): Item {
    let clone = new Item();

    // Assignment will copy primitive types

    clone.somePrimitiveType = this.somePrimitiveType;

    // Explicitly deep copy the reference types

    clone.someRefType = {
      someProperty: this.someRefType.someProperty
    };

    return clone;
  }
}

Then call clone() on each item:

this.backupData = this.genericItems.map(item => item.clone());

If you set the margin to be margin:0 auto the image will be centered.

This will give top + bottom a margin of 0, and left and right a margin of 'auto'. Since the div has a width (200px), the image will be 200px wide and the browser will auto set the left and right margin to half of what is left on the page, which will result in the image being centered.

you can not do it in this way

Use the following instead

typedef struct
{
   int id;
   char* name;
}employee;

employee emp = {
.id = 0, 
.name = "none"
};

You can use macro to define and initialize your instances. this will make easiier to you each time you want to define new instance and initialize it.

typedef struct
{
   int id;
   char* name;
}employee;

#define INIT_EMPLOYEE(X) employee X = {.id = 0, .name ="none"}

and in your code when you need to define new instance with employee type, you just call this macro like:

INIT_EMPLOYEE(emp);

Here's how to list local branches that do not have a remote branch in origin with the same name:

git branch | sed 's|* |  |' | sort > local
git branch -r | sed 's|origin/||' | sort > remote
comm -23 local remote

You can also use reduce method:

>>> myList = [3, 5, 4, 9]
>>> myTotal = reduce(lambda x,y: x+y, myList)
>>> myTotal
21

Furthermore, you can modify the lambda function to do other operations on your list.

If you want a more intuitive writing, it exist a gem called squeel that will let you write your instruction like this:

User.where{id > 200}

Notice the 'brace' characters { } and id being just a text.

All you have to do is to add squeel to your Gemfile:

gem "squeel"

This might ease your life a lot when writing complex SQL statement in Ruby.

Just try below script:

Below code works only if studentid column datatype is varchar

SELECT * FROM STUDENTS WHERE STUDENTID like '%Searchstring%'

The syntax to statically initialize an array uses curly braces, like this:

int array[10] = { 0 };

This will zero-initialize the array.

For multi-dimensional arrays, you need nested curly braces, like this:

int cipher[Array_size][Array_size]= { { 0 } };

Note that Array_size must be a compile-time constant for this to work. If Array_size is not known at compile-time, you must use dynamic initialization. (Preferably, an std::vector).

This is one of the method to overcome this issue.

• Just put the prototype in the header files and include the header files in the .cpp files as shown below.

You don't have to implement your own FIFO Queue, just look at the interface java.util.Queue and its implementations

Two options:

char c1 = '\u0001';

Based on luttken's answer. Thought I'd add my twist :)

function dateIsInBetween(\DateTime $from, \DateTime $to, \DateTime $subject)
{
    return $subject->getTimestamp() > $from->getTimestamp() && $subject->getTimestamp() < $to->getTimestamp() ? true : false;
}

$paymentDate       = new \DateTime('now');
$contractDateBegin = new \DateTime('01/01/2001');
$contractDateEnd   = new \DateTime('01/01/2016');

echo dateIsInBetween($contractDateBegin, $contractDateEnd, $paymentDate) ? "is between" : "NO GO!";

Provide the following in the search dialog:

Find What: ^$\r\n
Replace With: (Leave it empty)

Click Replace All

simply,

select sysdate-1 from dual

If you want to play nice with Windows file paths (under Cygwin) you can also try this:

fname=${fullfile##*[/|\\]}

This will account for backslash separators when using BaSH on Windows.

This query will give both field value and length:

db.usercollection.aggregate([
{
    $project: {
        "name": 1,
        "length": { $strLenCP: "$name" }
    }} ])

This can be a IPv6 problem (the host publishes an IPv6 AAAA-Address and the users host thinks it is configured for IPv6 but it is actually not correctly connected). This can also be a network MTU problem, a firewall block, or the target host might publish different IP addresses (randomly or based on originators country) which are not all reachable. Or similliar network problems.

You cant do much besides setting a timeout and adding good error messages (especially printing out the hosts' resolved address). If you want to make it more robust add retry, parallel trying of all addresses and also look into name resolution caching (positive and negative) on the Java platform.

For me - I just went here:

https://console.developers.google.com/apis/credentials

Then chose the right project; then choose the credential with the same ID shown in your console error message. When editing the credentials you can add multiple origins to the white list.

This is not actually a problem with the function being "void", but a problem with the function parameters. I think it's just g++ giving an unhelpful error message.

EDIT: As in the accepted answer, the fix is to use std::string instead of just string.

You can create with javascript some css-rules, which you can later use in your styles: http://jsfiddle.net/ARTsinn/vKbda/

var addRule = (function (sheet) {
    if(!sheet) return;
    return function (selector, styles) {
        if (sheet.insertRule) return sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
        if (sheet.addRule) return sheet.addRule(selector, styles);
    }
}(document.styleSheets[document.styleSheets.length - 1]));

var i = 101;
while (i--) {
    addRule("[data-width='" + i + "%']", "width:" + i + "%");
}

This creates 100 pseudo-selectors like this:

[data-width='1%'] { width: 1%; }
[data-width='2%'] { width: 2%; }
[data-width='3%'] { width: 3%; }
...
[data-width='100%'] { width: 100%; }

Note: This is a bit offtopic, and not really what you (or someone) wants, but maybe helpful.

After doing some testing, building upon the suggestions in the previous answers, there seem to be two usable solutions.

Method 1 is fastest, but less powerful in terms of matching more complex patterns.
Method 2 is more flexible, but slower.

Method 1 - fastest
I've tested this method on a table with 1 million rows.
It seems to be 3.8 times faster than the regex solutions.
The 0-replacement solves the issue that 0 is mapped to a space, and does not seem to slow down the query.

SELECT *
FROM <table>
WHERE TRANSLATE(replace(<char_column>,'0',''),'0123456789',' ') IS NOT NULL;

Method 2 - slower, but more flexible
I've compared the speed of putting the negation inside or outside the regex statement. Both are equally slower than the translate-solution. As a result, @ciuly's approach seems most sensible when using regex.

SELECT *
FROM <table>
WHERE NOT REGEXP_LIKE(<char_column>, '^[0-9]+$');

It is not necessary to explicitly unlink the old symlink. You can do this:

ln -s newtarget temp
mv temp mylink

(or use the equivalent symlink and rename calls). This is better than explicitly unlinking because rename is atomic, so you can be assured that the link will always point to either the old or new target. However this will not reuse the original inode.

On some filesystems, the target of the symlink is stored in the inode itself (in place of the block list) if it is short enough; this is determined at the time it is created.

Regarding the assertion that the actual owner and group are immaterial, symlink(7) on Linux says that there is a case where it is significant:

The owner and group of an existing symbolic link can be changed using lchown(2). The only time that the ownership of a symbolic link matters is when the link is being removed or renamed in a directory that has the sticky bit set (see stat(2)).

The last access and last modification timestamps of a symbolic link can be changed using utimensat(2) or lutimes(3).

On Linux, the permissions of a symbolic link are not used in any operations; the permissions are always 0777 (read, write, and execute for all user categories), and can't be changed.

First of all, all the reasons are subjective. It's more like a matter of taste rather than a reason.

Personally, I find heredoc quite useless and use it occasionally, most of the time when I need to get some HTML into a variable and don't want to bother with output buffering, to form an HTML email message for example.

Formatting doesn't fit general indentation rules, but I don't think it's a big deal.

       //some code at it's proper level
       $this->body = <<<HERE
heredoc text sticks to the left border
but it seems OK to me.
HERE;
       $this->title = "Feedback";
       //and so on

As for the examples in the accepted answer, it is merely cheating.
String examples, in fact, being more concise if one won't cheat on them

$sql = "SELECT * FROM $tablename
        WHERE id in [$order_ids_list]
        AND product_name = 'widgets'";

$x = 'The point of the "argument" was to illustrate the use of here documents';

Ned Deily's solution works perfectly fine, provided your user is allowed to sudo.

If he's not, you can su to an admin account, then use his dscl . append /Groups/_developer GroupMembership $user, where $user is the username.

However, I mistakenly thought it did not because I wrongly typed in the user's name in the command and it silently fails.

Therefore, after entering this command, you should proof-check it. This will check if $user is in $group, where the variables represent respectively the user name and the group name.

dsmemberutil checkmembership -U $user -G $group

This command will either print the message user is not a member of the group or user is a member of the group.

In my case the Data provider entry for MySQL was "simply" missing in the machine.config file described above (though I had installed the MySQL connector properly)

<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />

Don't forget to put the right Version of your MySQL on the Entry

In addition to existing answers I'd like to mention that sometimes it might be useful to have extension methods for IConfiguration for simplicity's sake.

I keep JWT config in appsettings.json so my extension methods class looks as follows:

public static class ConfigurationExtensions
{
    public static string GetIssuerSigningKey(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Authentication:JwtBearer:SecurityKey");
        return result;
    }

    public static string GetValidIssuer(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Authentication:JwtBearer:Issuer");
        return result;
    }

    public static string GetValidAudience(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Authentication:JwtBearer:Audience");
        return result;
    }

    public static string GetDefaultPolicy(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Policies:Default");
        return result;
    }

    public static SymmetricSecurityKey GetSymmetricSecurityKey(this IConfiguration configuration)
    {
        var issuerSigningKey = configuration.GetIssuerSigningKey();
        var data = Encoding.UTF8.GetBytes(issuerSigningKey);
        var result = new SymmetricSecurityKey(data);
        return result;
    }

    public static string[] GetCorsOrigins(this IConfiguration configuration)
    {
        string[] result =
            configuration.GetValue<string>("App:CorsOrigins")
            .Split(",", StringSplitOptions.RemoveEmptyEntries)
            .ToArray();

        return result;
    }
}

It saves you a lot of lines and you just write clean and minimal code:

...
x.TokenValidationParameters = new TokenValidationParameters()
{
    ValidateIssuerSigningKey = true,
    ValidateLifetime = true,
    IssuerSigningKey = _configuration.GetSymmetricSecurityKey(),
    ValidAudience = _configuration.GetValidAudience(),
    ValidIssuer = _configuration.GetValidIssuer()
};

It's also possible to register IConfiguration instance as singleton and inject it wherever you need - I use Autofac container here's how you do it:

var appConfiguration = AppConfigurations.Get(WebContentDirectoryFinder.CalculateContentRootFolder());
builder.Register(c => appConfiguration).As<IConfigurationRoot>().SingleInstance();

You can do the same with MS Dependency Injection:

services.AddSingleton<IConfigurationRoot>(appConfiguration);

ok, so my problem was that I tried to install the package with yum which is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories.

But I'm using ubuntu and The usual way to install packages on the command line in Ubuntu is with apt-get. so the right command was:

sudo apt-get install libstdc++.i686

My simple solution which works perfectly. You should to add a flag. My code snippet:

editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            if (after < count) {
                isBackspaceClicked = true;
            } else {
                isBackspaceClicked = false;
            }
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) { }

        @Override
        public void afterTextChanged(Editable s) {
            if (!isBackspaceClicked) {
                // Your current code
            } else {
                // Your "backspace" handling
            }
        }

Just after your Page_Load add this:

public override void VerifyRenderingInServerForm(Control control)
{
    //base.VerifyRenderingInServerForm(control);
}

Note that I don't do anything in the function.

EDIT: Tim answered the same thing. :) You can also find the answer Here

The key parameter is: innodb_page_size

Support for 32k and 64k page sizes was added in MySQL 5.7. For both 32k and 64k page sizes, the maximum row length is approximately 16000 bytes.

The trick is that this parameter can be only changed during the INITIALIZATION of the mysql service instance, so it does not have any affect if you change this parameter after the instance is already initialized (the very first run of the instance).

innodb_page_size can only be configured prior to initializing the MySQL instance and cannot be changed afterward. If no value is specified, the instance is initialized using the default page size. See Section 14.6.1, “InnoDB Startup Configuration”.

So if you do not change this value in my.ini before initialization, the default value will be 16K, which will have row size limit of ~8K. Thats why the error comes up.

If you increase the innodb_page_size, the innodb_log_buffer_size must be also increased. Set it at least to 16M. Also if the ROW_FORMAT is set to COMPRESSED you cannot increase innodb_page_size to 32k, or 64K. It should be DYNAMIC (default in 5.7).

ROW_FORMAT=COMPRESSED is not supported when innodb_page_size is set to 32KB or 64KB. For innodb_page_size=32k, extent size is 2MB. For innodb_page_size=64k, extent size is 4MB. innodb_log_buffer_size should be set to at least 16M (the default) when using 32k or 64k page sizes.

Furthermore the innodb_buffer_pool_size should be increased from 128M to 512M at least, otherwise you will get an error on initialization of the instance (I do not have the exact error).

After this, the row size error gone.

The problem with this is that you have to create a new MySql instance, and migrate data to your new DataBase instance, from old one.

Parameters that I changed and works (after creating a new instance and initialized with the my.ini that is first modified with these settings):

innodb_page_size=64k
innodb_log_buffer_size=32M
innodb_buffer_pool_size=512M

All the settings and descriptions in which I found the solution can be found here:

https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html

Hope this helps!

Regards!

You should take a look to the format method of python. You could then define your formatting string like this :

>>> s = '{0} BLAH BLAH {1} BLAH {2} BLAH BLIH BLEH'
>>> x = ['1', '2', '3']
>>> print s.format(*x)
'1 BLAH BLAH 2 BLAH 3 BLAH BLIH BLEH'

Setting an Initial Catalog allows you to set the database that queries run on that connection will use by default. If you do not set this for a connection to a server in which multiple databases are present, in many cases you will be required to have a USE statement in every query in order to explicitly declare which database you are trying to run the query on. The Initial Catalog setting is a good way of explicitly declaring a default database.

You can use:

$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);

Jsfiddle

Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.

Do it with inline styles and script:

<div class="btn-group has-feedback has-clear">
    <input id="searchinput" type="search" class="form-control" style="width:200px;">
        <a 
id="searchclear" 
class="glyphicon glyphicon-remove-circle form-control-feedback form-control-clear" 
style="pointer-events:auto; text-decoration:none; cursor:pointer;"
onclick="$(this).prev('input').val('');return false;">
</a>
</div>

Since the getTime function of the Date object gets the milliseconds since 1970/01/01, we can do this:

var time = '12:23:00';
var seconds = new Date('1970-01-01T' + time + 'Z').getTime() / 1000;

BootFlat

You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:

In that case, it isn't space that is in prefix/suffix.
The 1st row looks OK. Do the following for the contents of 2nd row.

ASCII(RIGHT(ProductAlternateKey, 1))

and

ASCII(LEFT(ProductAlternateKey, 1))

try using:

def extractAll(self,tag):

attention to self

I made a solution based in part by the information above. I just set the titleLabel.text to the string I want to pass, and set the titleLabel.hidden = YES

Like this :

    UIButton *imageclick = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
    imageclick.frame = photoframe;
    imageclick.titleLabel.text = [NSString stringWithFormat:@"%@.%@", ti.mediaImage, ti.mediaExtension];
    imageclick.titleLabel.hidden = YES;

This way, there is no need for a inheritance or category and there is no memory leak

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

This worked for me.

 1. git fetch --all
 2. git reset --hard origin/{branch_name}

You may want to look at jQuery Sortable. I used it to reorder table rows.

You can do it using the Github API

This is the Python example:

import requests


if __name__ == '__main__':
    base_api_url = 'https://api.github.com/repos'
    git_repository_url = 'https://github.com/garysieling/wikipedia-categorization.git'

    github_username, repository_name = git_repository_url[:-4].split('/')[-2:]  # garysieling and wikipedia-categorization
    res = requests.get(f'{base_api_url}/{github_username}/{repository_name}')
    repository_size = res.json().get('size')
    print(repository_size)

Add following dll files to bin folder:

DotNetOpenAuth.AspNet.dll
DotNetOpenAuth.Core.dll
DotNetOpenAuth.OAuth.Consumer.dll
DotNetOpenAuth.OAuth.dll
DotNetOpenAuth.OpenId.dll
DotNetOpenAuth.OpenId.RelyingParty.dll

If you will not need them, delete dependentAssemblies from config named 'DotNetOpenAuth.Core' etc..

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. more info : http://en.wikipedia.org/wiki/Cascading_Style_Sheets CSS is not a programming language, and does not have the tools that come with a server side language like PHP. However, we can use Server-side languages to generate style sheets.

<html>
<head>
<title>...</title>

while($row = mysql_fetch_row($result))

Try new_list = a[0:2] + [a[4]] + a[6:].

Or more generally, something like this:

from itertools import chain
new_list = list(chain(a[0:2], [a[4]], a[6:]))

This works with other sequences as well, and is likely to be faster.

Or you could do this:

def chain_elements_or_slices(*elements_or_slices):
    new_list = []
    for i in elements_or_slices:
        if isinstance(i, list):
            new_list.extend(i)
        else:
            new_list.append(i)
    return new_list

new_list = chain_elements_or_slices(a[0:2], a[4], a[6:])

But beware, this would lead to problems if some of the elements in your list were themselves lists. To solve this, either use one of the previous solutions, or replace a[4] with a[4:5] (or more generally a[n] with a[n:n+1]).

Check this out : readdir()

This bit of code should list all entries in a certain directory:

if ($handle = opendir('.')) {

    while (false !== ($entry = readdir($handle))) {

        if ($entry != "." && $entry != "..") {

            echo "$entry\n";
        }
    }

    closedir($handle);
}

Edit: miah's solution is much more elegant than mine, you should use his solution instead.

in my case, datas is an objects of Array for more information please Click Here

<% for(let [index,data] of datas.entries() || []){  %>
 Index : <%=index%>
 Data : <%=data%>
<%} %>

Try this code

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:<your ViewController object>];

[self.view.window.rootViewController presentViewController:navigationController animated:YES completion:nil];

these extras prove useful.. need to be executed as an administrator

sc create  <service_name> binpath=<binary_path>
sc stop    <service_name>
sc queryex <service_name>
sc delete  <service_name>

If your service name has any spaces, enclose in "quotes".

I suspect that the real issue here is that your test runner is copying your assembly to a different location. There's no way at runtime to tell where the assembly was copied from, but you can probably flip a switch to tell the test runner to run the assembly from where it is and not to copy it to a shadow directory.

Such a switch is likely to be different for each test runner, of course.

Have you considered embedding your XML data as resources inside your test assembly?

Use the getColor(Resources, int, Theme) method of the ResourcesCompat from the Android Support Library.

int white = ResourcesCompat.getColor(getResources(), R.color.white, null);

I think it reflect better your question than the getColor(Context, int) of the ContextCompat since you ask about Resources. Prior to API level 23, the theme will not be applied and the method calls through to getColor(int) but you'll not have the deprecated warning. The theme also may be null.

This should work:

ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")

The kind of array definition seems the key: In my case it is a one dimension array of 17 items which have to convert to a two dimension array

Defintion for columns: object[,] Array = new object[17, 1];

Defintion for rows object[,] Array= new object[1,17];

The code for value2 is in both cases the same Excel.Range cell = activeWorksheet.get_Range(Range); cell.Value2 = Array;

This is another regex which I have learned to love/hate over the last week so usually import as (in this case yes) something that reflects how im feeling! make a normal function.... ask for input, then use ....something = re.compile(r'foo*|spam*', yes.I)...... re.I (yes.I below) is the same as IGNORECASE but you cant make as many mistakes writing it!

You then search your message using regex's but honestly that should be a few pages in its own , but the point is that foo or spam are piped together and case is ignored. Then if either are found then lost_n_found would display one of them. if neither then lost_n_found is equal to None. If its not equal to none return the user_input in lower case using "return lost_n_found.lower()"

This allows you to much more easily match up anything thats going to be case sensitive. Lastly (NCS) stands for "no one cares seriously...!" or not case sensitive....whichever

if anyone has any questions get me on this..

    import re as yes

    def bar_or_spam():

        message = raw_input("\nEnter FoO for BaR or SpaM for EgGs (NCS): ") 

        message_in_coconut = yes.compile(r'foo*|spam*',  yes.I)

        lost_n_found = message_in_coconut.search(message).group()

        if lost_n_found != None:
            return lost_n_found.lower()
        else:
            print ("Make tea not love")
            return

    whatz_for_breakfast = bar_or_spam()

    if whatz_for_breakfast == foo:
        print ("BaR")

    elif whatz_for_breakfast == spam:
        print ("EgGs")

Put the line in a stringstream and extract word by word back:

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

int main()
{
    string t;
    getline(cin,t);

    istringstream iss(t);
    string word;
    while(iss >> word) {
        /* do stuff with word */
    }
}

Of course, you can just skip the getline part and read word by word from cin directly.

And here you can read why is using namespace std considered bad practice.

It's a very late answer but I resolved the issue turning off the lazy loading:

db.Configuration.LazyLoadingEnabled = false;

Using pure JPA with Hibernate 5.0.2.Final as the actual provider the following seems to work with positional parameters as well:

Entity.java:

@Entity
@NamedQueries({
    @NamedQuery(name = "byAttributes", query = "select e from Entity e where e.attribute in (?1)") })
public class Entity {
    @Column(name = "attribute")
    private String attribute;
}

Dao.java:

public class Dao {
    public List<Entity> findByAttributes(Set<String> attributes) {
        Query query = em.createNamedQuery("byAttributes");
        query.setParameter(1, attributes);

        List<Entity> entities = query.getResultList();
        return entities;
    }
}

Assuming that you have posted valid JSON,

@app.route('/api/add_message/<uuid>', methods=['GET', 'POST'])
def add_message(uuid):
    content = request.json
    print content['uuid']
    # Return data as JSON
    return jsonify(content)

This one also works

1. Remove the "php.executablePath" line from the VS code settings.

2. Then add the xampp php path to the System variables

After that restart the Visual Studio Code

Here is a really fast and easy way of setting it permanently

NB: running SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); is temporary and on server restart you will still end up with the error. To fix this permanently do the below

1. Login to your server as root
2. in your terminal run wget https://gist.githubusercontent.com/nfourtythree/90fb8ef5eeafdf478f522720314c60bd/raw/disable-strict-mode.sh
3. Make the script executable by running chmod +x disable-strict-mode.sh
4. Run the script by running ./disable-strict-mode.sh

And your done , changes will be made to mysql and it will be restarted

You can do it easily with regex:

string subject = "(913)-444-5555";
string result = Regex.Replace(subject, "[^0-9]", ""); // result = "9134445555"

Make sure you are using default gradle wrapper in Open File > Settings > Build,Execution,Deployment > Build Tools > Gradle.

rosipov's rule works great!

I use it on live sites to display a blank or special message ;) in place of a direct access attempt to files I'd rather to protect a bit from direct view. I think it's more fun than a 403 Forbidden.

So taking rosipov's rule to redirect any direct request to {gif,jpg,js,txt} files to 'messageforcurious' :

RewriteEngine on 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?domain\.ltd [NC] 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?domain\.ltd.*$ [NC] 
RewriteRule \.(gif|jpg|js|txt)$ /messageforcurious [L]

I see it as a polite way to disallow direct acces to, say, a CMS sensible files like xml, javascript... with security in mind: To all these bots scrawling the web nowadays, I wonder what their algo will make from my 'messageforcurious'.

This is the simplest wat to get the File object to which a certain URL object is pointing at:

File file=new File(url.toURI());

Now, for your concrete questions:

• finding all resources in the META-INF "directory":

You can indeed get the File object pointing to this URL

Enumeration<URL> en=getClass().getClassLoader().getResources("META-INF");
if (en.hasMoreElements()) {
    URL metaInf=en.nextElement();
    File fileMetaInf=new File(metaInf.toURI());

    File[] files=fileMetaInf.listFiles();
    //or 
    String[] filenames=fileMetaInf.list();
}

• all resources named bla.xml (recursivly)

In this case, you'll have to do some custom code. Here is a dummy example:

final List<File> foundFiles=new ArrayList<File>();

FileFilter customFilter=new FileFilter() {
    @Override
    public boolean accept(File pathname) {

        if(pathname.isDirectory()) {
            pathname.listFiles(this);
        }
        if(pathname.getName().endsWith("bla.xml")) {
            foundFiles.add(pathname);
            return true;
        }
        return false;
    }

};      
//rootFolder here represents a File Object pointing the root forlder of your search 
rootFolder.listFiles(customFilter);

When the code is run, you'll get all the found ocurrences at the foundFiles List.

How to avoid copy-paste?

Let's face it: this one appears a lot when recording macros:

Range("X1").Select
Selection.Copy
Range("Y9).Select
Selection.Paste

While the only thing the person wants is:

Range("Y9").Value = Range("X1").Value

Therefore, instead of using copy-paste in VBA macros, I'd advise the following simple approach:

Destination_Range.Value = Source_Range.Value

I think you can normalize the row elements sum to 1 by this: new_matrix = a / a.sum(axis=1, keepdims=1). And the column normalization can be done with new_matrix = a / a.sum(axis=0, keepdims=1). Hope this can hep.

The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element to do DOM operations. The method defined in the directive controller is accessible in the main controller.

Example, finding a child element:

var app = angular.module('myapp', []);
app.directive("testDir", function () {
    function link(scope, element) { 

    }
    return {
        restrict: "AE", 
        link: link, 
        controller:function($scope,$element){
            $scope.name2 = 'this is second name';
            var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
    }
    };
})

app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});

I know this is an oldie but here is a quick way to hide the scroll bar with pure CSS.

Just add

::-webkit-scrollbar {display:none;}

To your id or class of the div you're using the scroll bar with.

Here is a helpful link Custom Scroll Bar in Webkit

If you are talking about the length of the string, you can use len():

>>> s = 'please answer my question'
>>> len(s)  # number of characters in s
25

If you need the size of the string in bytes, you need sys.getsizeof():

>>> import sys
>>> sys.getsizeof(s)
58

Also, don't call your string variable str. It shadows the built-in str() function.

For Python 3.x, use input(). For Python 2.x, use raw_input(). Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!").

Function convert image to base64 using jquery (you can convert to vanila js). Hope it help to you!

Usage: input is your nameId input has file image

<input type="file" id="asd"/>
<button onclick="proccessData()">Submit</button>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>

async function converImageToBase64(inputId) {
  let image = $('#'+inputId)[0]['files']

  if (image && image[0]) {
    const reader = new FileReader();

    return new Promise(resolve => {
      reader.onload = ev => {
        resolve(ev.target.result)
      }
      reader.readAsDataURL(image[0])
    })
  }
}

async function proccessData() {
  const image = await converImageToBase64('asd')
  console.log(image)
}

</script>

Example: converImageToBase64('yourFileInputId')

Below is the code that you may try to read a file and display in java using scanner class. Code will read the file name from user and print the data(Notepad VIM files).

import java.io.*;
import java.util.Scanner;
import java.io.*;

public class TestRead
{
public static void main(String[] input)
{
    String fname;
    Scanner scan = new Scanner(System.in);

    /* enter filename with extension to open and read its content */

    System.out.print("Enter File Name to Open (with extension like file.txt) : ");
    fname = scan.nextLine();

    /* this will reference only one line at a time */

    String line = null;
    try
    {
        /* FileReader reads text files in the default encoding */
        FileReader fileReader = new FileReader(fname);

        /* always wrap the FileReader in BufferedReader */
        BufferedReader bufferedReader = new BufferedReader(fileReader);

        while((line = bufferedReader.readLine()) != null)
        {
            System.out.println(line);
        }

        /* always close the file after use */
        bufferedReader.close();
    }
    catch(IOException ex)
    {
        System.out.println("Error reading file named '" + fname + "'");
    }
}

}

Maybe you could use String#split

To answer your comment:

I'm not sure if there can be more than one . in a filename, but whatever, even if there are more dots you can use the split. Consider e.g. that:

String input = "boo.and.foo";

String[] result = input.split(".");

This will return an array containing:

{ "boo", "and", "foo" }

So you will know that the last index in the array is the extension and all others are the base.

I'm using yarn. I had to do the following to overcome the error.

The below command can be used to take dump from docker postgress container

A useful alternative answer to the first question, using the examples from tomeedee’s answer, would be to use numpy’s vstack and column_stack methods:

Given a matrix p,

>>> import numpy as np
>>> p = np.array([ [1,2] , [3,4] ])

an augmented matrix can be generated by:

>>> p = np.vstack( [ p , [5 , 6] ] )
>>> p = np.column_stack( [ p , [ 7 , 8 , 9 ] ] )
>>> p
array([[1, 2, 7],
       [3, 4, 8],
       [5, 6, 9]])

These methods may be convenient in practice than np.append() as they allow 1D arrays to be appended to a matrix without any modification, in contrast to the following scenario:

>>> p = np.array([ [ 1 , 2 ] , [ 3 , 4 ] , [ 5 , 6 ] ] )
>>> p = np.append( p , [ 7 , 8 , 9 ] , 1 )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/dist-packages/numpy/lib/function_base.py", line 3234, in append
    return concatenate((arr, values), axis=axis)
ValueError: arrays must have same number of dimensions

In answer to the second question, a nice way to remove rows and columns is to use logical array indexing as follows:

Given a matrix p,

>>> p = np.arange( 20 ).reshape( ( 4 , 5 ) )

suppose we want to remove row 1 and column 2:

>>> r , c = 1 , 2
>>> p = p [ np.arange( p.shape[0] ) != r , : ] 
>>> p = p [ : , np.arange( p.shape[1] ) != c ]
>>> p
array([[ 0,  1,  3,  4],
       [10, 11, 13, 14],
       [15, 16, 18, 19]])

Note - for reformed Matlab users - if you wanted to do these in a one-liner you need to index twice:

>>> p = np.arange( 20 ).reshape( ( 4 , 5 ) )    
>>> p = p [ np.arange( p.shape[0] ) != r , : ] [ : , np.arange( p.shape[1] ) != c ]

This technique can also be extended to remove sets of rows and columns, so if we wanted to remove rows 0 & 2 and columns 1, 2 & 3 we could use numpy's setdiff1d function to generate the desired logical index:

>>> p = np.arange( 20 ).reshape( ( 4 , 5 ) )
>>> r = [ 0 , 2 ]
>>> c = [ 1 , 2 , 3 ]
>>> p = p [ np.setdiff1d( np.arange( p.shape[0] ), r ) , : ] 
>>> p = p [ : , np.setdiff1d( np.arange( p.shape[1] ) , c ) ]
>>> p
array([[ 5,  9],
       [15, 19]])

There are two basic kinds of recursions: head recursion and tail recursion.

In head recursion, a function makes its recursive call and then performs some more calculations, maybe using the result of the recursive call, for example.

In a tail recursive function, all calculations happen first and the recursive call is the last thing that happens.

Taken from this super awesome post. Please consider reading it.

Default Usage

Get the meta for all keys:

<?php $meta = get_post_meta($post_id); ?>

Get the meta for a single key:

<?php $key_1_values = get_post_meta( 76, 'key_1' ); ?>

for example:

$myvals = get_post_meta($post_id);

foreach($myvals as $key=>$val)
{
    echo $key . ' : ' . $val[0] . '<br/>';
}

Note: some unwanted meta keys starting with "underscore(_)" will also come, so you will need to filter them out.

For reference: See Codex

I know this question is tagged as C# but the concepts are pretty generic questions like this redirect here. So I am going to provide my point of view here (a bit biased from java point of view where I am more comfortable).

When we think of Object-oriented nature we always think of Objects, class (objects blueprints) and the relationship between them. Objects are related and interact with each other via methods. In other words the object of one class may use services/methods provided by the object of another class. This kind of relationship is termed as association..

Aggregation and Composition are subsets of association meaning they are specific cases of association.

• In both aggregation and composition object of one class "owns" object of another class.
• But there is a subtle difference. In Composition the object of class that is owned by the object of it's owning class cannot live on it's own(Also called "death relationship"). It will always live as a part of it's owning object where as in Aggregation the dependent object is standalone and can exist even if the object of owning class is dead.
• So in composition if owning object is garbage collected the owned object will also be which is not the case in aggregation.

Confused?

Composition Example : Consider the example of a Car and an engine that is very specific to that car (meaning it cannot be used in any other car). This type of relationship between Car and SpecificEngine class is called Composition. An object of the Car class cannot exist without an object of SpecificEngine class and object of SpecificEngine has no significance without Car class. To put in simple words Car class solely "owns" the SpecificEngine class.

Aggregation Example : Now consider class Car and class Wheel. Car needs a Wheel object to function. Meaning the Car object owns the Wheel object but we cannot say the Wheel object has no significance without the Car Object. It can very well be used in a Bike, Truck or different Cars Object.

Summing it up -

To sum it up association is a very generic term used to represent when a class uses the functionalities provided by another class. We say it's composition if one parent class object owns another child class object and that child class object cannot meaningfully exist without the parent class object. If it can then it is called Aggregation.

More details here. I am the author of http://opensourceforgeeks.blogspot.in and have added a link above to the relevant post for more context.

$(window).scroll(function(){
    $('#header').css({
        'left': $(this).scrollLeft() + 15 
         //Why this 15, because in the CSS, we have set left 15, so as we scroll, we would want this to remain at 15px left
    });
});

You can check if the Google Play Store app is installed and, if this is the case, you can use the "market://" protocol.

final String my_package_name = "........."  // <- HERE YOUR PACKAGE NAME!!
String url = "";

try {
    //Check whether Google Play store is installed or not:
    this.getPackageManager().getPackageInfo("com.android.vending", 0);

    url = "market://details?id=" + my_package_name;
} catch ( final Exception e ) {
    url = "https://play.google.com/store/apps/details?id=" + my_package_name;
}


//Open the app page in Google Play store:
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
startActivity(intent);

Debugging Summary

• Check for typo error: username or password.
• Check the host name and compare it with mysql.user table host name.
• Check user exists or not.
• Check whether host contains IP address or host name.

There is a great chance that, you might have encountered this issue multiple times in your work. This issue occurred to me most of times due to the incorrectly entering user name or password. Though this is one of the reasons, there are other many chances you might get this issue. Sometimes, it looks very similar, but when you dig deeper, you will realize multiple factors contributing to this error. This post will explain in detail, most of the common reasons and work around to fix this issue.

Possible reasons:

• Case 1: Typo error: username or password.

This is the most common reason for this error. If you entered the username or password wrongly, surely you will get this error.

Solution:

Solution for this type of error is very simple. Just enter the correct username and password. This error will be resolved. In case if you forget the password you can reset the username/password. If you forget the password for admin / root account, there are many ways to reset / recapture the root password. I will publish another post on how to reset the root password in-case if you forget root password.

• Case 2: Accessing from wrong host.

MySQL provides host based restriction for user access as a security features. In our production environment, we used to restrict the access request only to the Application servers. This feature is really helpful in many production scenarios.

Solution:

When you face this type of issue, first check whether your host is allowed or not by checking the mysql.user table. If it is not defined, you can update or insert new record to mysql.user table. Generally, accessing as a root user from remote machine is disabled and it is not a best practice, because of security concerns. If you have requirements to access your server from multiple machines, give access only to those machines. It is better not to use wildcards (%) and gives universal accesses. Let me update the mysql.user table, now the demouser can access MySQL server from any host.

• Case 3: User does not exists on the server.

This type of error occurs when the user, which you are trying to access not exist on the MySQL server.

Solutions:

When you face this type of issue, just check whether the user is exists in mysql.user table or not. If the record not exists, user cannot access. If there is a requirement for that user to access, create a new user with that username.

• Case 4: Mix of numeric and name based hosts.

Important points

• It is not advisable to use wildcards while defining user host, try to use the exact host name.

• Disable root login from remote machine.

• Use proxy user concept.

There are few other concepts related with this topic and getting into details of those topics is very different scope of this article. We will look into the following related topics in the upcoming articles.

• What to do, if you forgot root password in of MySQL server.
• MySQL Access privilege issues and user related tables.
• MySQL security features with best practices.

I hope this post will help for you to fix the MySQL Error Code 1045 Access denied for user in MySQL.

After spending about 5 hours, this solution worked for me..

First add this line to your manifest tag if you do not have yet:

xmlns:tools="http://schemas.android.com/tools"

Example:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.winanainc"
    android:versionCode="3"
    android:versionName="1.2"
    xmlns:tools="http://schemas.android.com/tools">

Then Add this meta tag inside your application to overwrite you build tools version, in this case for example I choosed the version 25.3.1

<application>
   ...
   ..
    <meta-data
        tools:replace="android:value"
        android:name="android.support.VERSION"
        android:value="25.3.1" />
</application>

You are using collapse on the div inside of your table row (tr). So when you collapse the div, the row is still there. You need to change it to where your id and class are on the tr instead of the div.

Change this:

<tr><td><div class="collapse out" id="collapseme">Should be collapsed</div></td></tr>

to this:

<tr class="collapse out" id="collapseme"><td><div>Should be collapsed</div></td></tr>

JSFiddle: http://jsfiddle.net/KnuU6/21/

EDIT: If you are unable to upgrade to 3.0.0, I found a JQuery workaround in 2.3.2:

Remove your data-toggle and data-target and add this JQuery to your button.

$(".btn").click(function() {
    if($("#collapseme").hasClass("out")) {
        $("#collapseme").addClass("in");
        $("#collapseme").removeClass("out");
    } else {
        $("#collapseme").addClass("out");
        $("#collapseme").removeClass("in");
    }
});

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

PHP extensions for Ubuntu 20.04 LTS (Focal Fossa)

PHP extensions for Ubuntu 18.04 LTS (Bionic)

PHP extensions for Ubuntu 16.04 LTS (Xenial)

If compareParents(s1, s2) == -1 then compareParents(s2, s1) == 1 is expected. With your code it's not always true.

Specifically if s1.getParent() == s2 && s2.getParent() == s1. It's just one of the possible problems.

If you are looking for Swift 3, Follow the steps to achieve this:

func viewDidLoad() {

    //Define Layout here
    let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()

    //Get device width
    let width = UIScreen.main.bounds.width

    //set section inset as per your requirement.
    layout.sectionInset = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)

    //set cell item size here 
    layout.itemSize = CGSize(width: width / 2, height: width / 2)

    //set Minimum spacing between 2 items
    layout.minimumInteritemSpacing = 0

    //set minimum vertical line spacing here between two lines in collectionview
    layout.minimumLineSpacing = 0

    //apply defined layout to collectionview
    collectionView!.collectionViewLayout = layout

}

This is verified on Xcode 8.0 with Swift 3.

If you use nano with a language like python (as in your example) it's also a good idea to convert tabs to spaces.

Edit your ~/.nanorc file (or create it) and add:

set tabsize 4
set tabstospaces

If you already got a file with tabs and want to convert them to spaces i recommend the expandcommand (shell):

expand -4 input.py > output.py

Just to clarify the Training/Validation/Test data sets: The training set is used to perform the initial training of the model, initializing the weights of the neural network.

The validation set is used after the neural network has been trained. It is used for tuning the network's hyperparameters, and comparing how changes to them affect the predictive accuracy of the model. Whereas the training set can be thought of as being used to build the neural network's gate weights, the validation set allows fine tuning of the parameters or architecture of the neural network model. It's useful as it allows repeatable comparison of these different parameters/architectures against the same data and networks weights, to observe how parameter/architecture changes affect the predictive power of the network.

Then the test set is used only to test the predictive accuracy of the trained neural network on previously unseen data, after training and parameter/architecture selection with the training and validation data sets.

This can actually be done with only CSS, but the content inside the div must be absolutely positioned. The key is to use padding as a percentage and the box-sizing: border-box CSS attribute:

div {_x000D_
  border: 1px solid red;_x000D_
  width: 40%;_x000D_
  padding: 40%;_x000D_
  box-sizing: border-box;_x000D_
  position: relative;_x000D_
}_x000D_
p {_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
}

<div>_x000D_
  <p>Some unnecessary content.</p>_x000D_
</div>

Adjust percentages to your liking. Here is a JSFiddle

function myFunction() {
  var sheetname = "DateEntry";//Sheet where you want to put the date
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetname);
    // You could use now Date(); on its own but it will not look nice.
  var date = Utilities.formatDate(new Date(), "GMT+5:30", "yyyy-MM-dd");
    //var endDate = date;
    sheet.getRange(sheet.getLastRow() + 1,1).setValue(date); //Gets the last row which had value, and goes to the next empty row to put new values.
}

since answers are disappointing I would like suggest a way in which I got deleted stuff back.

I use an ide to code and accidently I used rm -rf from terminal to remove complete folder. Thanks to ide I recoved it back by reverting the change from ide's local history.

Note that the '=' is optional in C++11 universal initialization syntax, and it is generally considered better style to write :

It should be pretty obvious from your question that you're actually just asking about the difference between git merge and git rebase.

So let's suppose you're in the common case - you've done some work on your master branch, and you pull from origin's, which also has done some work. After the fetch, things look like this:

- o - o - o - H - A - B - C (master)
               \
                P - Q - R (origin/master)

If you merge at this point (the default behavior of git pull), assuming there aren't any conflicts, you end up with this:

- o - o - o - H - A - B - C - X (master)
               \             /
                P - Q - R --- (origin/master)

If on the other hand you did the appropriate rebase, you'd end up with this:

- o - o - o - H - P - Q - R - A' - B' - C' (master)
                          |
                          (origin/master)

The content of your work tree should end up the same in both cases; you've just created a different history leading up to it. The rebase rewrites your history, making it look as if you had committed on top of origin's new master branch (R), instead of where you originally committed (H). You should never use the rebase approach if someone else has already pulled from your master branch.

Finally, note that you can actually set up git pull for a given branch to use rebase instead of merge by setting the config parameter branch.<name>.rebase to true. You can also do this for a single pull using git pull --rebase.

a.h:

#ifndef A_H
#define A_H

struct a { 
    int i;
    struct b {
        int j;
    }
};

#endif

there you go, now you just need to include a.h to the files where you want to use this structure.

1:n means 'one-to-many'; you have two tables, and each row of table A may be referenced by any number of rows in table B, but each row in table B can only reference one row in table A (or none at all).

n:m (or n:n) means 'many-to-many'; each row in table A can reference many rows in table B, and each row in table B can reference many rows in table A.

A 1:n relationship is typically modelled using a simple foreign key - one column in table A references a similar column in table B, typically the primary key. Since the primary key uniquely identifies exactly one row, this row can be referenced by many rows in table A, but each row in table A can only reference one row in table B.

A n:m relationship cannot be done this way; a common solution is to use a link table that contains two foreign key columns, one for each table it links. For each reference between table A and table B, one row is inserted into the link table, containing the IDs of the corresponding rows.

The list selector drawable is a StateListDrawable — it contains reference to multiple drawables for each state the list can be, like selected, focused, pressed, disabled...

While you can retrieve the drawable using getSelector(), I don't believe you can retrieve a specific Drawable from a StateListDrawable, nor does it seem possible to programmatically retrieve the colour directly from a ColorDrawable anyway.

As for setting the colour, you need a StateListDrawable as described above. You can set this on your list using the android:listSelector attribute, defining the drawable in XML like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_enabled="false" android:state_focused="true"
        android:drawable="@drawable/item_disabled" />
  <item android:state_pressed="true"
        android:drawable="@drawable/item_pressed" />
  <item android:state_focused="true"
        android:drawable="@drawable/item_focused" />
</selector>

Using copy_if:

#include <string>
#include <iostream>
#include <algorithm>
int main() {
    std::string s1 = "a1a2b3c4a5";
    char s2[256];
    std::copy_if(s1.begin(), s1.end(), s2, [](char c){return c!='a';});
    std::cout << s2 << std::endl;
    return 0;
}

Description of the possible values:

• left: No floating elements allowed on the left side
• right: No floating elements allowed on the right side
• both: No floating elements allowed on either the left or the right side
• none: Default. Allows floating elements on both sides
• inherit: Specifies that the value of the clear property should be inherited from the parent element

I had this problem in Visual Studio 2013. I reinstalled NuGet Package Manager:

https://marketplace.visualstudio.com/items?itemName=NuGetTeam.NuGetPackageManagerforVisualStudio2013

Just correct Google play services dependencies:

You are including all play services in your project. Only add those you want.

For example , if you are using only maps and g+ signin, than change

 compile 'com.google.android.gms:play-services:8.1.0'

to

compile 'com.google.android.gms:play-services-maps:8.1.0'
compile 'com.google.android.gms:play-services-plus:8.1.0'

From the doc :

In versions of Google Play services prior to 6.5, you had to compile the entire package of APIs into your app. In some cases, doing so made it more difficult to keep the number of methods in your app (including framework APIs, library methods, and your own code) under the 65,536 limit.

From version 6.5, you can instead selectively compile Google Play service APIs into your app. For example, to include only the Google Fit and Android Wear APIs, replace the following line in your build.gradle file:
compile 'com.google.android.gms:play-services:8.3.0'
with these lines:

compile 'com.google.android.gms:play-services-fitness:8.3.0'
compile 'com.google.android.gms:play-services-wearable:8.3.0'

Whole list can be found here.

Other way is with:

np.vectorize(lambda x: 6 <= x <= 10)(a)

which returns:

array([False, False, False,  True,  True,  True, False, False, False])

It is sometimes useful for masking time series, vectors, etc.

you can't get city location by ip. here you can get country with jquery:

$.get("http://ip-api.com/json", function(response) {
console.log(response.country);}, "jsonp");

No, that's not possible. The port is not part of the hostname, so it has no meaning in the hosts-file.

Try:

move "C:\files\*.txt" "C:\txt"

Please use ctrl+s on Windows or ?s on Mac (while the emulator is focused). Your Desktop should be the default save location.

Its very simple you just add this script,

$("#mydate").datepicker({ dateFormat: "yy-mm-dd"}).datepicker("setDate", new Date());

Here, setDate set today date & dateFormat define which format you want set or show.

Hope its simple script work..

I added opacity to the line, so it seems thinner:

<hr style="opacity: 0.25">

Here is a slightly simpler version that I found. It reads the entire file in one go and only requires a single using directive.

byte[] ComputeHash(string filePath)
{
    using (var md5 = MD5.Create())
    {
        return md5.ComputeHash(File.ReadAllBytes(filePath));
    }
}

You can explicitly tell Eclipse where to find it. Open eclipse.ini and add the following lines to the top of the file:

-vm
/absolute/path/to/jre6/bin

Update: I just nailed down the root cause on my own Windows machine. The GlassFish installer complained with exactly the same error message and after digging in GlassFish forums, the cause was clear: a corrupt JRE install on a Windows machine. My JRE came along with the JDK and the Java 6 JDK installer didn't install the JRE properly somehow. A DLL file was missing in JDK's JRE installation. After I reinstalled the standalone JRE from http://java.com, overwriting the old one, the GlassFish installer continued and also Eclipse was able to start flawlessly without those two lines in eclipse.ini.

A class with a field:

Public Class MyStudent
   Public StudentId As Integer

The constructor:

    Public Sub New(newStudentId As Integer)
        StudentId = newStudentId
    End Sub
End Class

This is my answer

#include<stdio.h>
int main()
{int mat[100][100];
int row,column,i,j;
printf("enter how many row and colmn you want:\n \n");
scanf("%d",&row);
scanf("%d",&column);
printf("enter the matrix:");

for(i=0;i<row;i++){
    for(j=0;j<column;j++){
        scanf("%d",&mat[i][j]);
    }

printf("\n");
}

for(i=0;i<row;i++){
    for(j=0;j<column;j++){
        printf("%d \t",mat[i][j]);}

printf("\n");}
}

I just choose an approximate value for the row and column. My selected row or column will not cross the value.and then I scan the matrix element then make it in matrix size.

If you need direct access:

WScript.Arguments.Item(0)
WScript.Arguments.Item(1)
...

Usual way to empty textbox using jquery is:

$('#txtInput').val('');

If above code is not working than please check that you are able to get the input element.

console.log($('#txtInput')); // should return element in the console.

If still facing the same problem, please post your code.

I discovered that the higher the value of 'width' is, the smaller the box width is made and vice versa. I found this out because I had the same problem earlier. So:

.inner-wrapper {
    width: 1%;
}

solves the problem.

You can't influence neither type (tab/window) nor dimensions that way. You'll have to use JavaScript's window.open() for that.

According to HTML living standard specification, the load event is

Fired at the Window when the document has finished loading; fired at an element containing a resource (e.g. img, embed) when its resource has finished loading

I.e. load event is not fired on document object.

Try this:

The reason is that the argument for end is passed by reference, since end modifies the array by advancing its internal pointer to the final element. If you're not passing a variable in, there's nothing for a reference to point to.

This is similar to CommonsWare answer but with a minor tweak: android:gravity="top|start". Complete code example:

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

The @Profile annotation allows you to indicate that a component is eligible for registration when one or more specified profiles are active. Using our example above, we can rewrite the dataSource configuration as follows:

@Configuration
@Profile("dev")
public class StandaloneDataConfig {

    @Bean
    public DataSource dataSource() {
        return new EmbeddedDatabaseBuilder()
            .setType(EmbeddedDatabaseType.HSQL)
            .addScript("classpath:com/bank/config/sql/schema.sql")
            .addScript("classpath:com/bank/config/sql/test-data.sql")
            .build();
    }
}

And other one:

@Configuration
@Profile("production")
public class JndiDataConfig {

    @Bean(destroyMethod="")
    public DataSource dataSource() throws Exception {
        Context ctx = new InitialContext();
        return (DataSource) ctx.lookup("java:comp/env/jdbc/datasource");
    }
}

The known problem with the templates is code bloating, which is consequence of generating the class definition in each and every module which invokes the class template specialization. To prevent this, starting with C++0x, one could use the keyword extern in front of the class template specialization

#include <MyClass>
extern template class CMyClass<int>;

The explicit instantion of the template class should happen only in a single translation unit, preferable the one with template definition (MyClass.cpp)

template class CMyClass<int>;
template class CMyClass<float>;

This will work for a multiple row df having the dataframe as df with the same name of the columns in the df as the db.

tuples = list(df.itertuples(index=False, name=None))

columns_list = df.columns.tolist()
marks = ['?' for _ in columns_list]
columns_list = f'({(",".join(columns_list))})'
marks = f'({(",".join(marks))})'

table_name = 'whateveryouwant'

c.executemany(f'INSERT OR REPLACE INTO {table_name}{columns_list} VALUES {marks}', tuples)
conn.commit()

The get property works great, and you can also use a binded closure for "expensive" functions that should only run once (this only works with var, not with const or let)

var info = {
  address: (function() {
    return databaseLookup(this.id)
  }).bind(info)(),

  get fullName() {
    console.log('computing fullName...')
    return `${this.first} ${this.last}`
  },

  id: '555-22-9999',
  first: 'First',
  last: 'Last',
}

function databaseLookup() {
  console.log('fetching address from remote server (runs once)...')
  return Promise.resolve(`22 Main St, City, Country`)
}

// test
(async () => {
  console.log(info.fullName)
  console.log(info.fullName)
  console.log(await info.address)
  console.log(await info.address)
  console.log(await info.address)
  console.log(await info.address)
})()

This should do the trick:

$('#some_select_box').click(function() {
  $('option:selected', this ).remove();
});

Depending on what you want to accomplish, you might replace INSERT with INSERT IGNORE in your file. This will avoid generating an error for the rows that you are trying to insert and already exist.

Another point to add.

Overloading More than one method with Same name. Same or different return type. Different no of parameters or Different type of parameters. In Same Class or Derived class.

int Add(int num1, int num2) int Add(int num1, int num2, int num3) double Add(int num1, int num2) double Add(double num1, double num2)

Can be possible in same class or derived class. Generally prefers in same class. E.g. Console.WriteLine() has 19 overloaded methods.

Can overload class constructors, methods.

Can consider as Compile Time (static / Early Binding) polymorphism.

=====================================================================================================

Overriding cannot be possible in same class. Can Override class methods, properties, indexers, events.

Has some limitations like The overridden base method must be virtual, abstract, or override. You cannot use the new, static, or virtual modifiers to modify an override method.

Can Consider as Run Time (Dynamic / Late Binding) polymorphism.
