I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

One note on the above answers: it is no longer sufficient to add just pypi.python.org to the trusted-hosts in the case where you are behind an HTTPS-intercepting proxy (we have zScaler).

I currently have the following in my pip.ini:

trusted-host = pypi.python.org pypi.org files.pythonhosted.org

Running pip -v install pkg will give you some hints as to which hosts might need to be added.

This did the trick for me:

   sudo pip install scrapy --ignore-installed six

I would use Celery to handle the asynchronous task for you. You'll need to install a broker to serve as your task queue (RabbitMQ and Redis are recommended).

app.py:

from flask import Flask
from celery import Celery

broker_url = 'amqp://guest@localhost'          # Broker URL for RabbitMQ task queue

app = Flask(__name__)    
celery = Celery(app.name, broker=broker_url)
celery.config_from_object('celeryconfig')      # Your celery configurations in a celeryconfig.py

@celery.task(bind=True)
def some_long_task(self, x, y):
    # Do some long task
    ...

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    data = json.loads(request.data)
    text_list = data.get('text_list')
    final_file = audio_class.render_audio(data=text_list)
    some_long_task.delay(x, y)                 # Call your async task and pass whatever necessary variables
    return Response(
        mimetype='application/json',
        status=200
    )

Run your Flask app, and start another process to run your celery worker.

$ celery worker -A app.celery --loglevel=debug

I would also refer to Miguel Gringberg's write up for a more in depth guide to using Celery with Flask.

Make sure you pip version matches your python version.

to get your python version use:

python -V

then install the correct pip. You might already have intall in that case try to use:

pip-2.5 install ...

pip-2.7 install ...

or for those of you using macports make sure your version match using.

port select --list pip

then change to the same python version you are using.

sudo port select --set pip pip27

Hope this helps. It work on my end.

Here is the example from the SocketServer documentation which would make an excellent starting point

import SocketServer

class MyTCPHandler(SocketServer.BaseRequestHandler):
    """
    The RequestHandler class for our server.

    It is instantiated once per connection to the server, and must
    override the handle() method to implement communication to the
    client.
    """

    def handle(self):
        # self.request is the TCP socket connected to the client
        self.data = self.request.recv(1024).strip()
        print "{} wrote:".format(self.client_address[0])
        print self.data
        # just send back the same data, but upper-cased
        self.request.sendall(self.data.upper())

if __name__ == "__main__":
    HOST, PORT = "localhost", 9999

    # Create the server, binding to localhost on port 9999
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler)

    # Activate the server; this will keep running until you
    # interrupt the program with Ctrl-C
    server.serve_forever()

Try it from a terminal like this

$ telnet localhost 9999
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Hello
HELLOConnection closed by foreign host.
$ telnet localhost 9999
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Sausage
SAUSAGEConnection closed by foreign host.

You'll probably need to use A Forking or Threading Mixin too

its on you ul in the file http://ratest4.com/wp-content/themes/HarnettArts-BP-2010/style.css on line 252

add this to your css

ul{
     list-style:none;
}

You can always do it with a break from a loop construct or a labeled break as specified in aioobies answer.

public static void main(String[] args) {
    do {
        try {
            // code..
            if (condition)
                break;
            // more code...
        } catch (Exception e) {

        }
    } while (false);
}

Websockets use sockets in their implementation. Websockets are based on a standard protocol (now in final call, but not yet final) that defines a connection "handshake" and message "frame." The two sides go through the handshake procedure to mutually accept a connection and then use the standard message format ("frame") to pass messages back and forth.

I'm developing a framework that will allow you to communicate directly machine to machine with installed software. It might suit your purpose. You can follow my blog if you wish: http://highlevellogic.blogspot.com/2011/09/websocket-server-demonstration_26.html

The PyMsgBox module does exactly this. It has message box functions that follow the naming conventions of JavaScript: alert(), confirm(), prompt() and password() (which is prompt() but uses * when you type). These function calls block until the user clicks an OK/Cancel button. It's a cross-platform, pure Python module with no dependencies outside of tkinter.

Install with: pip install PyMsgBox

Sample usage:

import pymsgbox
pymsgbox.alert('This is an alert!', 'Title')
response = pymsgbox.prompt('What is your name?')

We are developing Versile Python (VPy), an implementation for python 2.6+ and 3.x of a new ORB/RPC framework. Functional AGPL dev releases for review and testing are available. VPy has native python capabilities similar to PyRo and RPyC via a general native objects layer (code example). The product is designed for platform-independent remote object interaction for implementations of Versile Platform.

Full disclosure: I work for the company developing VPy.

I was having the same problem but wanted to minimize 3rd party dependencies (because this one-off script was to be executed by many users). My solution was to wrap a curl call and make sure that the exit code was 0. Worked like a charm.

You could also check out paramiko. There's no scp module (yet), but it fully supports sftp.

[EDIT] Sorry, missed the line where you mentioned paramiko. The following module is simply an implementation of the scp protocol for paramiko. If you don't want to use paramiko or conch (the only ssh implementations I know of for python), you could rework this to run over a regular ssh session using pipes.

scp.py for paramiko

I tried a number of the solutions above however the fix in our scenario was to install the fpm-module.

We had installed httpd before php which may have had something to do with the issue, but to resolve we installed the following:

yum module install php:7.2

This installed the php-fpm-7.2.11-4.module+el8.1.0+5443+bc1aeb77.x86_64.rpm module which we then enabled by:

systemctl enable --now php-fpm

From that point we left the /etc/httpd/conf.d/php.conf as default and restarted httpd

service httpd restart

Then everything worked.

Hope this helps, took way longer than it should have to figure out.

you are using onclick which is javascript event. there is two ways

Javascript

<input type="button" value="Home" class="homebutton" id="btnHome" 
onClick="window.location = 'http://google.com'" />

Or PHP

create another page as redirect.php and put

<?php header('location : google.com') ?>

and insert this link on any page within the same directory

<a href="redirect.php">google<a/>

hope this helps its simplest!!

You could do something like this

dict = [{
   "id": 1,
   "name": "Doom Hammer"
 },
 {
    "id": 2,
    "name": "Rings ov Saturn"
 }
]

for x in dict:
  if x["id"] == 2:
    print(x["name"])

Thats what i use to find the objects in a long array of objects.

/*You might be looking something like this?

grep -vn "gloom" `grep -l "loom" ~/projects/**/trunk/src/**/*.@(h|cpp)`

The BACKQUOTES are used like brackets for commands, so in this case with -l enabled, the code in the BACKQUOTES will return you the file names, then with -vn to do what you wanted: have filenames, linenumbers, and also the actual lines.

UPDATE Or with xargs

grep -l "loom" ~/projects/**/trunk/src/**/*.@(h|cpp) | xargs grep -vn "gloom"

Hope that helps.*/

Please ignore what I've written above, it's rubbish.

grep -n "loom" `grep -l "loom" tt4.txt` | grep -v "gloom"

               #this part gets the filenames with "loom"
#this part gets the lines with "loom"
                                          #this part gets the linenumber,
                                          #filename and actual line

This may be new:

https://artifactory.example.com/artifactory/repo/com/example/foo/1.0.[RELEASE]/foo-1.0.[RELEASE].tgz

For loading module foo from example.com . Keep the [RELEASE] parts verbatim. This is mentioned in the docs but it's not made abundantly clear that you can actually put [RELEASE] into the URL (as opposed to a substitution pattern for the developer).

There is a way to call the init() method once and forbid it's usage, you can turn the function into private initializer and ivoke it after class declaration like this:

class Example {
    private static function init() {
        // do whatever needed for class initialization
    }
}
(static function () {
    static::init();
})->bindTo(null, Example::class)();

update Angular 5

ngOutletContext was renamed to ngTemplateOutletContext

See also https://github.com/angular/angular/blob/master/CHANGELOG.md#500-beta5-2017-08-29

original

Templates (<template>, or <ng-template> since 4.x) are added as embedded views and get passed a context.

With let-col the context property $implicit is made available as col within the template for bindings. With let-foo="bar" the context property bar is made available as foo.

For example if you add a template

<ng-template #myTemplate let-col let-foo="bar">
  <div>{{col}}</div>
  <div>{{foo}}</div>
</ng-template>

<!-- render above template with a custom context -->
<ng-template [ngTemplateOutlet]="myTemplate"
             [ngTemplateOutletContext]="{
                                           $implicit: 'some col value',
                                           bar: 'some bar value'
                                        }"
></ng-template>

See also this answer and ViewContainerRef#createEmbeddedView.

*ngFor also works this way. The canonical syntax makes this more obvious

<ng-template ngFor let-item [ngForOf]="items" let-i="index" let-odd="odd">
  <div>{{item}}</div>
</ng-template>

where NgFor adds the template as embedded view to the DOM for each item of items and adds a few values (item, index, odd) to the context.

If you ever wondered how to do it using the new BDD style of Mockito:

willThrow(new Exception()).given(mockedObject).methodReturningVoid(...));

And for future reference one may need to throw exception and then do nothing:

willThrow(new Exception()).willDoNothing().given(mockedObject).methodReturningVoid(...));

jQuery code snippet to get the dynamic variables stored in the url as parameters and store them as JavaScript variables ready for use with your scripts:

$.urlParam = function(name){
    var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
    if (results==null){
       return null;
    }
    else{
       return results[1] || 0;
    }
}

example.com?param1=name&param2=&id=6

$.urlParam('param1'); // name
$.urlParam('id');        // 6
$.urlParam('param2');   // null

//example params with spaces
http://www.jquery4u.com?city=Gold Coast
console.log($.urlParam('city'));  
//output: Gold%20Coast

console.log(decodeURIComponent($.urlParam('city'))); 
//output: Gold Coast

If you want to call it more like Math.Max, you can do something like this very short expression body:

public static DateTime Max(params DateTime[] dates) => dates.Max();
[...]
var lastUpdatedTime = DateMath.Max(feedItemDateTime, assemblyUpdatedDateTime);

This Error hit me after installing RVM correctly. Solution: re-boot Terminal.

Reference RailsCast's RVM Install tutorial.

You could iterate over the anonymous type's properties using Reflection; see if there is a "Checked" property and if there is then get its value.

See this blog post: http://blogs.msdn.com/wriju/archive/2007/10/26/c-3-0-anonymous-type-and-net-reflection-hand-in-hand.aspx

So something like:

foreach(object o in nodes)
{
    Type t = o.GetType();

    PropertyInfo[] pi = t.GetProperties(); 

    foreach (PropertyInfo p in pi)
    {
        if (p.Name=="Checked" && !(bool)p.GetValue(o))
            Console.WriteLine("awesome!");
    }
}

In a UIView extension:

func addBlurredBackground(style: UIBlurEffect.Style) {
    let blurEffect = UIBlurEffect(style: style)
    let blurView = UIVisualEffectView(effect: blurEffect)
    blurView.frame = self.frame
    blurView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    self.addSubview(blurView)
    self.sendSubviewToBack(blurView)
}

f = open('list1.txt')
f1 = open('output.txt', 'a')

# doIHaveToCopyTheLine=False

for line in f.readlines():
    if 'tests/file/myword' in line:
        f1.write(line)

f1.close()
f.close()

Now Your code will work. Try This one.

You can use the following command to access with your ip.

ng serve --host 0.0.0.0 --disable-host-check

If you are using npm and want to avoid running the command every time, we can add the following line to the package.json file in the scripts section.

"scripts": {
    ...
    "start": "ng serve --host 0.0.0.0 --disable-host-check"
    ...
}

Then you can run you app using the below command to be accessed from the other system in the same network.

npm start

element.offsetWidth and element.offsetHeight should do, as suggested in previous post.

However, if you just want to center the content, there is a better way of doing so. Assuming you use xhtml strict DOCTYPE. set the margin:0,auto property and required width in px to the body tag. The content gets center aligned to the page.

Er ... how about in a boolean function to indicate 'not true'?

You can solve the issue by clearing value of address in endpoint tag in web.config:

<endpoint address="" name="wsHttpEndpoint"  .......           />

The print function in python adds itself \n

You could use

import sys
sys.stdout.write(a)

instead

^\+[1-9]{1}[0-9]{7,11}$ 

The Regular Expression ^\+[1-9]{1}[0-9]{7,11}$ fails for "+290 8000" and similar valid numbers that are shorter than 8 digits.

The longest numbers could be something like 3 digit country code, 3 digit area code, 8 digit subscriber number, making 14 digits.

In order to map a the result set of query to a particular Java class you'll probably be best (assuming you're interested in using the object elsewhere) off with a RowMapper to convert the columns in the result set into an object instance.

See Section 12.2.1.1 of Data access with JDBC on how to use a row mapper.

In short, you'll need something like:

List<Conversation> actors = jdbcTemplate.query(
    SELECT_ALL_CONVERSATIONS_SQL_FULL,
    new Object[] {userId, dateFrom, dateTo},
    new RowMapper<Conversation>() {
        public Conversation mapRow(ResultSet rs, int rowNum) throws SQLException {
            Conversation c = new Conversation();
            c.setId(rs.getLong(1));
            c.setRoom(rs.getString(2));
            [...]
            return c;
        }
    });

If you have a pd.Series object x with index named 'Gene', you can use reset_index and supply the name argument:

df = x.reset_index(name='count')

Here's a demo:

x = pd.Series([2, 7, 1], index=['Ezh2', 'Hmgb', 'Irf1'])
x.index.name = 'Gene'

df = x.reset_index(name='count')

print(df)

   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

The CLI's webpack config can now be ejected. Check Anton Nikiforov's answer.

outdated:

You can hack the config template in angular-cli/addon/ng2/models. There's no official way to modify the webpack config as of now.

There's a closed "wont-fix" issue on github about this: https://github.com/angular/angular-cli/issues/1656

Today you can also use the unipath package which was based on path.py: http://sluggo.scrapping.cc/python/unipath/

>>> from unipath import Path
>>> absolute_path = Path('mydir/myfile.txt').absolute()
Path('C:\\example\\cwd\\mydir\\myfile.txt')
>>> str(absolute_path)
C:\\example\\cwd\\mydir\\myfile.txt
>>>

I would recommend using this package as it offers a clean interface to common os.path utilities.

I'm having exactly the same problem. The only workaround I've found, is to replace the fragments by a new instance, each time the tabs are changed.

ft.replace(R.id.fragment_container, Fragment.instantiate(PlayerMainActivity.this, fragment.getClass().getName()));

Not a real solution, but i haven't found a way to reuse the previous fragment instance...

There is a subtle difference in terms of conflict management. In case of conflicts, a pull request in Github will result in a merge commit on the destination branch. In Gitlab, when a conflict is found, the modifications made will be on a merge commit on the source branch.

See https://docs.gitlab.com/ee/user/project/merge_requests/resolve_conflicts.html

"GitLab resolves conflicts by creating a merge commit in the source branch that is not automatically merged into the target branch. This allows the merge commit to be reviewed and tested before the changes are merged, preventing unintended changes entering the target branch without review or breaking the build."

I'd suggest:

document.querySelector('.rateRecipe.btns-one-small').click();

The above code assumes that the given element has both of those classes; otherwise, if the space is meant to imply an ancestor-descendant relationship:

document.querySelector('.rateRecipe .btns-one-small').click();

The method getElementsByClassName() takes a single class-name (rather than document.querySelector()/document.querySelectorAll(), which take a CSS selector), and you passed two (presumably class-names) to the method.

References:

• document.getElementsByClassName().
• document.querySelector().

Android Documentation on Manifest.permission.Manifest.permission.WRITE_EXTERNAL_STORAGE states:

Starting in API level 19, this permission is not required to read/write files in your application-specific directories returned by getExternalFilesDir(String) and getExternalCacheDir().

I think that this means you do not have to code for the run-time implementation of the WRITE_EXTERNAL_STORAGE permission unless the app is writing to a directory that is not specific to your app.

You can define the max sdk version in the manifest per permission like:

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="19" />

Also make sure to change the target SDK in the build.graddle and not the manifest, the gradle settings will always overwrite the manifest settings.

android {
compileSdkVersion 23
buildToolsVersion '23.0.1'
defaultConfig {
    minSdkVersion 17
    targetSdkVersion 22
}

Here is how you can do it using strtotime(),

<?php
    $date = strtotime("3 October 2005");
    $d = strtotime("+7 day", $date);
    echo "Created date is " . date("Y-m-d h:i:sa", $d) . "<br>";
?>

mime-types starting with x- are not standardized. In case of javascript it's kind of outdated. Additional the second code snippet

<?Header('Content-Type: text/javascript');?>

requires short_open_tags to be enabled. you should avoid it.

<?php Header('Content-Type: text/javascript');?>

However, the completely correct mime-type for javascript is

application/javascript

const express = require('express');                                                                                                                           
const morgan = require('morgan')
const PORT = 3000;

morgan.token('port', (req) => { 
    return req.app.locals.port; 
});

const app = express();
app.locals.port = PORT;
app.use(morgan(':method :url :port'))
app.get('/app', function(req, res) {
    res.send("Hello world from server");
});

app1.listen(PORT);

I had same problem and finally I understood that my node version is old. For example, you can install the current active LTS node version in Ubuntu by the following steps:

sudo apt-get update
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install nodejs -y

Installation instructions for more versions and systems can be found in the following link:

https://github.com/nodesource/distributions/blob/master/README.md

The error message "Please update your includePath" does not necessarily mean there is actually a problem with the includePath. The problem may be that VSCode is using the wrong compiler or wrong IntelliSense mode. I have written instructions in this answer on how to troubleshoot and align your VSCode C++ configuration with your compiler and project.

The transparent parts mostly have RGBA value (0,0,0,0). Since the JPG has no transparency, the jpeg value is set to (0,0,0), which is black.

Around the circular icon, there are pixels with nonzero RGB values where A = 0. So they look transparent in the PNG, but funny-colored in the JPG.

You can set all pixels where A == 0 to have R = G = B = 255 using numpy like this:

import Image
import numpy as np

FNAME = 'logo.png'
img = Image.open(FNAME).convert('RGBA')
x = np.array(img)
r, g, b, a = np.rollaxis(x, axis = -1)
r[a == 0] = 255
g[a == 0] = 255
b[a == 0] = 255
x = np.dstack([r, g, b, a])
img = Image.fromarray(x, 'RGBA')
img.save('/tmp/out.jpg')

Note that the logo also has some semi-transparent pixels used to smooth the edges around the words and icon. Saving to jpeg ignores the semi-transparency, making the resultant jpeg look quite jagged.

A better quality result could be made using imagemagick's convert command:

convert logo.png -background white -flatten /tmp/out.jpg

To make a nicer quality blend using numpy, you could use alpha compositing:

import Image
import numpy as np

def alpha_composite(src, dst):
    '''
    Return the alpha composite of src and dst.

    Parameters:
    src -- PIL RGBA Image object
    dst -- PIL RGBA Image object

    The algorithm comes from http://en.wikipedia.org/wiki/Alpha_compositing
    '''
    # http://stackoverflow.com/a/3375291/190597
    # http://stackoverflow.com/a/9166671/190597
    src = np.asarray(src)
    dst = np.asarray(dst)
    out = np.empty(src.shape, dtype = 'float')
    alpha = np.index_exp[:, :, 3:]
    rgb = np.index_exp[:, :, :3]
    src_a = src[alpha]/255.0
    dst_a = dst[alpha]/255.0
    out[alpha] = src_a+dst_a*(1-src_a)
    old_setting = np.seterr(invalid = 'ignore')
    out[rgb] = (src[rgb]*src_a + dst[rgb]*dst_a*(1-src_a))/out[alpha]
    np.seterr(**old_setting)    
    out[alpha] *= 255
    np.clip(out,0,255)
    # astype('uint8') maps np.nan (and np.inf) to 0
    out = out.astype('uint8')
    out = Image.fromarray(out, 'RGBA')
    return out            

FNAME = 'logo.png'
img = Image.open(FNAME).convert('RGBA')
white = Image.new('RGBA', size = img.size, color = (255, 255, 255, 255))
img = alpha_composite(img, white)
img.save('/tmp/out.jpg')

You can do it with 1 printf:

System.out.printf("First Name: %s\nLast Name: %s",firstname, lastname);

For a one time change you can do this:

export EMAIL='[email protected]'; mutt -s "Elvis is dead" [email protected]

In my case I found that I have an aggressive plugin for Vim, just restarted it.

Anybody working on legacy software using Visual Studio 6.0 will find that $(Configuration) and $(ProjectDir) macro's are not defined. For post-build/pre-build events, give a relative path starting with the location of your .dsw file(workspace) as the starting point. In relative path dot represents the current directory and .. represents the parent directory. Give a relative path to the file that need to be processed. Example: ( copy /y .\..\..\Debug\mylib.dll .\..\MyProject\Debug\ )

I find myself using the following often to get a limited number of revisions out of our huge subversion tree (we're soon reaching svn revision 35000).

# checkout a specific revision
git svn clone -r N svn://some/repo/branch/some-branch
# enter it and get all commits since revision 'N'
cd some-branch
git svn rebase

And a good way to find out where a branch started is to do a svn log it and find the first one on the branch (the last one listed when doing):

svn log --stop-on-copy svn://some/repo/branch/some-branch

So far I have not really found the hassle worth it in tracking all branches. It takes too much time to clone and svn and git don't work together as good as I would like. I tend to create patch files and apply them on the git clone of another svn branch.

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error($connection));
}

You got the order of the arguments to mysqli_select_db() backwards. And mysqli_error() requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.

Note also that with mysqli you can specify the DB in mysqli_connect():

$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
  die("Database connection failed: " . mysqli_connect_error();
}

You must use mysqli_connect_error(), not mysqli_error(), to get the error from mysqli_connect(), since the latter requires you to supply a valid connection.

Yes, it is definitely possible using Javascript Result:

return JavaScript("Callback()");

Javascript should be referenced by your view:

function Callback(){
    // do something where you can call an action method in controller to pass some data via AJAX() request
}

Are you sure it's not a Table-Valued Function?

The reason I ask:

CREATE FUNCTION dbo.chk_mgr(@mgr VARCHAR(50)) 
RETURNS @mgr_table TABLE (mgr_name VARCHAR(50))
AS
BEGIN 
  INSERT @mgr_table (mgr_name) VALUES ('pointy haired boss') 
  RETURN
END 
GO

SELECT dbo.chk_mgr('asdf')
GO

Result:

Msg 4121, Level 16, State 1, Line 1
Cannot find either column "dbo" or the user-defined function 
or aggregate "dbo.chk_mgr", or the name is ambiguous.

However...

SELECT * FROM dbo.chk_mgr('asdf') 

mgr_name
------------------
pointy haired boss

You need to tell the run to wait until the process is finished. Something like:

const DontWaitUntilFinished = false, ShowWindow = 1, DontShowWindow = 0, WaitUntilFinished = true
set oShell = WScript.CreateObject("WScript.Shell")
command = "cmd /c C:\windows\system32\wscript.exe <path>\myScript.vbs " & args
oShell.Run command, DontShowWindow, WaitUntilFinished

In the script itself, start Excel like so. While debugging start visible:

File = "c:\test\myfile.xls"
oShell.run """C:\Program Files\Microsoft Office\Office14\EXCEL.EXE"" " & File, 1, true

The reason the code in your question does not authenticate is because you are sending the auth in the data object, not in the config, which will put it in the headers. Per the axios docs, the request method alias for post is:

axios.post(url[, data[, config]])

Therefore, for your code to work, you need to send an empty object for data:

var session_url = 'http://api_address/api/session_endpoint';
var username = 'user';
var password = 'password';
var basicAuth = 'Basic ' + btoa(username + ':' + password);
axios.post(session_url, {}, {
  headers: { 'Authorization': + basicAuth }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

The same is true for using the auth parameter mentioned by @luschn. The following code is equivalent, but uses the auth parameter instead (and also passes an empty data object):

var session_url = 'http://api_address/api/session_endpoint';
var uname = 'user';
var pass = 'password';
axios.post(session_url, {}, {
  auth: {
    username: uname,
    password: pass
  }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

old question that I stumbled into that I believe deserves an update... You can infact execute javascript from the URL, and you can get creative about it too. I recently made a members only area that I wanted to remind someone what their password was, so I was looking for a non-local alert...of course you can embed an alert into the page itself, but then its public. the difference here is I can create a link and slip some JS into the href so clicking on the link will generate the alert.

here is what I mean >>

<a href="javascript:alert('the secret is to ask.');window.location.replace('http://google.com');">You can have anything</a>

and so upon clicking the link, the user is given an alert with the info, then they are taken to the new page.

obviously you could also write an onClick, but the href works just fine when you slip it through the URL, just remember to prepend it with "javascript:"

*works in chrome, didnt check anything else.

To attempt command line arguments directly is not possible.

One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).

This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html

so sudo systemctl restart myprog -v -- systemctl will think you're trying to set one of its flags, not myprog's flag.

sudo systemctl restart myprog someotheroption -- systemctl will restart myprog and the someotheroption service, if it exists.

series.str.cat is the most flexible way to approach this problem:

For df = pd.DataFrame({'foo':['a','b','c'], 'bar':[1, 2, 3]})

df.foo.str.cat(df.bar.astype(str), sep=' is ')

>>>  0    a is 1
     1    b is 2
     2    c is 3
     Name: foo, dtype: object

OR

df.bar.astype(str).str.cat(df.foo, sep=' is ')

>>>  0    1 is a
     1    2 is b
     2    3 is c
     Name: bar, dtype: object

Unlike .join() (which is for joining list contained in a single Series), this method is for joining 2 Series together. It also allows you to ignore or replace NaN values as desired.

In addition to the "raw" tools provided by MutationObserver API, there exist "convenience" libraries to work with DOM mutations.

Consider: MutationObserver represents each DOM change in terms of subtrees. So if you're, for instance, waiting for a certain element to be inserted, it may be deep inside the children of mutations.mutation[i].addedNodes[j].

Another problem is when your own code, in reaction to mutations, changes DOM - you often want to filter it out.

A good convenience library that solves such problems is mutation-summary (disclaimer: I'm not the author, just a satisfied user), which enables you to specify queries of what you're interested in, and get exactly that.

Basic usage example from the docs:

var observer = new MutationSummary({
  callback: updateWidgets,
  queries: [{
    element: '[data-widget]'
  }]
});

function updateWidgets(summaries) {
  var widgetSummary = summaries[0];
  widgetSummary.added.forEach(buildNewWidget);
  widgetSummary.removed.forEach(cleanupExistingWidget);
}

You have in your module

import {Routes, RouterModule} from '@angular/router';

you have to export the module RouteModule

example:

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})

to be able to access the functionalities for all who import this module.

    python 3.2


    >>>> from itertools import chain
    >>>> eg=sorted(list(set(list(chain(*eg)))), reverse=True)
        [7, 6, 5, 4, 3, 2, 1]


   ##### eg contain 2 list within a list. so if you want to use set() function
   you should flatten the list like [1, 2, 3, 4, 4, 5, 6, 7]

   >>> res= list(chain(*eg))       # [1, 2, 3, 4, 4, 5, 6, 7]                   
   >>> res1= set(res)                    #   [1, 2, 3, 4, 5, 6, 7]
   >>> res1= sorted(res1,reverse=True)

You need to write following code on controller suppose test is model, and Name, Address are field of this model.

public ActionResult MyMethod()
{
    Test test=new Test();
    var test.Name="John";
    return View(test);   
}

now use like like this on your view to give set value of hidden variable.

@model YourApplicationName.Model.Test

@Html.HiddenFor(m=>m.Name,new{id="hdnFlag"})

This will automatically set hidden value=john.

As a general statement, its good to make your if conditionals as readable as possible. For your example, using ! is ok. the problem is when things look like

if ((a.b && c.d.e) || !f)

you might want to do something like

bool isOk = a.b;
bool isStillOk = c.d.e
bool alternateOk = !f

then your if statement is simplified to

if ( (isOk && isStillOk) || alternateOk)

It just makes the code more readable. And if you have to debug, you can debug the isOk set of vars instead of having to dig through the variables in scope. It is also helpful for dealing with NPEs -- breaking code out into simpler chunks is always good.

just try this simple method: in controller:-

 public function index()
   {
        $data = array(
            'title' => 'Home',
            'otherData' => 'Data Here'
        );
        return view('front.landing')->with($data);
   }

And in you layout (app.blade.php) :

<title>{{ $title }} - {{ config('app.name') }} </title>

Thats all.

Unless you have very, very well-behaved data, this is a non-trivial challenge. A naive approach would be to tokenize on whitespace and assume that a three-token result is [first, middle, last] and a two-token result is [first, last], but you're going to have to deal with multi-word surnames (e.g. "Van Buren") and multiple middle names.

 [Route("api/controller/{one}/{two}")]
    public string Get(int One, int Two)
    {
        return "both params of the root link({one},{two}) and Get function parameters (one, two)  should be same ";
    }

Both params of the root link({one},{two}) and Get function parameters (one, two) should be same

The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.

Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.

* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).

i have same issue and resolved by

Important Answar
String name;
int roll;

public int compare(Object obj1,Object obj2) { // For Comparator interface
    return obj1.compareTo(obj1);
}

public int compareTo(Object obj1) { // For Comparable Interface
    return obj1.compareTo(obj);
}

Here in return obj1.compareTo(obj1) or return obj1.compareTo(obj) statement only take Object; primitive is not allowed. For Example

name.compareTo(obj1.getName()) // Correct Statement.

But

roll.compareTo(obj1.getRoll()) 
// Wrong Statement Compile Time Error Because roll 
// is not an Object Type, it is primitive type.

name is String Object so it worked. If you want to sort roll number of student than use below code.

public int compareTo(Object obj1) { // For Comparable Interface
    Student s = (Student) obj1;
    return rollno - s.getRollno();
}  

or

public int compare(Object obj1,Object obj2) { // For Comparator interface
    Student s1 = (Student) obj1;
    Student s2 = (Student) obj2;
    return s1.getRollno() - s2.getRollno();
}  

This occurs when one downloads using HTTPS rather than the SSH,easiet way which I implemented was I pushed everything as I made a few changes once wherein it asked for the username and password, then I removed the directory from my machine and git clone SSH address. It was solved.

Just clone it using SSH rather than HTTP and it won't ask for username or password.

Also having two-factor authentication creates the problem even when you download using SSH so disabling it solves the issue.

cesards's answer is correct, but only for API > 15. For lower API versions I decided to use getRunningTasks() method:

   private boolean isAppInForeground(Context context)
    {
        if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
        {
            ActivityManager am = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE);
            ActivityManager.RunningTaskInfo foregroundTaskInfo = am.getRunningTasks(1).get(0);
            String foregroundTaskPackageName = foregroundTaskInfo.topActivity.getPackageName();

            return foregroundTaskPackageName.toLowerCase().equals(context.getPackageName().toLowerCase());
        }
        else
        {
            ActivityManager.RunningAppProcessInfo appProcessInfo = new ActivityManager.RunningAppProcessInfo();
            ActivityManager.getMyMemoryState(appProcessInfo);
            if (appProcessInfo.importance == IMPORTANCE_FOREGROUND || appProcessInfo.importance == IMPORTANCE_VISIBLE)
            {
                return true;
            }

            KeyguardManager km = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
            // App is foreground, but screen is locked, so show notification
            return km.inKeyguardRestrictedInputMode();
        }
    }

Please, let me know if it works for you all.

Here's one-liner for any enum class:

public static String[] getNames(Class<? extends Enum<?>> e) {
    return Arrays.stream(e.getEnumConstants()).map(Enum::name).toArray(String[]::new);
}

Pre Java 8 is still a one-liner, albeit less elegant:

public static String[] getNames(Class<? extends Enum<?>> e) {
    return Arrays.toString(e.getEnumConstants()).replaceAll("^.|.$", "").split(", ");
}

That you would call like this:

String[] names = getNames(State.class); // any other enum class will work

If you just want something simple for a hard-coded enum class:

public static String[] names() {
    return Arrays.toString(State.values()).replaceAll("^.|.$", "").split(", ");
}

Have you thought about using the TAG "dt" instead of "ul" for nesting lists? It's inherit style and structure allow you to have a title per section and it automatically tabulates the content that goes inside.

<dl>
  <dt>Coffee</dt>
    <dd>Black hot drink</dd>
  <dt>Milk</dt>
    <dd>White cold drink</dd>
</dl>

VS

<ul>
   <li>Choice A</li>
   <li>Choice B
      <ul>
         <li>Sub 1</li>
         <li>Sub 2</li>
      </ul>
   </li>

The (very) short answer to your question is that paintComponent is called "when it needs to be." Sometimes it's easier to think of the Java Swing GUI system as a "black-box," where much of the internals are handled without too much visibility.

There are a number of factors that determine when a component needs to be re-painted, ranging from moving, re-sizing, changing focus, being hidden by other frames, and so on and so forth. Many of these events are detected auto-magically, and paintComponent is called internally when it is determined that that operation is necessary.

I've worked with Swing for many years, and I don't think I've ever called paintComponent directly, or even seen it called directly from something else. The closest I've come is using the repaint() methods to programmatically trigger a repaint of certain components (which I assume calls the correct paintComponent methods downstream.

In my experience, paintComponent is rarely directly overridden. I admit that there are custom rendering tasks that require such granularity, but Java Swing does offer a (fairly) robust set of JComponents and Layouts that can be used to do much of the heavy lifting without having to directly override paintComponent. I guess my point here is to make sure that you can't do something with native JComponents and Layouts before you go off trying to roll your own custom-rendered components.

There are several problems in your code.

First the big ones:

1. You are creating a new figure and a new axes in every iteration of your loop ? put fig = plt.figure and ax = fig.add_subplot(1,1,1) outside of the loop.

2. Don't use the Locators. Call the functions ax.set_xticks() and ax.grid() with the correct keywords.

3. With plt.axes() you are creating a new axes again. Use ax.set_aspect('equal').

The minor things: You should not mix the MATLAB-like syntax like plt.axis() with the objective syntax. Use ax.set_xlim(a,b) and ax.set_ylim(a,b)

This should be a working minimal example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)

# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)

ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)

# And a corresponding grid
ax.grid(which='both')

# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)

plt.show()

Output is this:

ClassLoader.getResourceAsStream().

As stated in the comment below, if you are in a multi-ClassLoader environment (such as unit testing, webapps, etc.) you may need to use Thread.currentThread().getContextClassLoader(). See http://stackoverflow.com/questions/2308188/getresourceasstream-vs-fileinputstream/2308388#comment21307593_2308388.

I want to add to the answers posted on above that none of the solutions proposed here worked for me. My WAMP, is working on port 3308 instead of 3306 which is what it is installed by default. I found out that when working in a local environment, if you are using mysqladmin in your computer (for testing environment), and if you are working with port other than 3306, you must define your variable DB_SERVER with the value localhost:NumberOfThePort, so it will look like the following: define("DB_SERVER", "localhost:3308"). You can obtain this value by right-clicking on the WAMP icon in your taskbar (on the hidden icons section) and select Tools. You will see the section: "Port used by MySQL: NumberOfThePort"

This will fix your connection to your database.

This was the error I got: Error: SQLSTATE[HY1045] Access denied for user 'username'@'localhost' on line X.

I hope this helps you out.

If it's running all of the above from the command line that you're looking for, then I'd recommend HTTPie. It is a fantastic cURL alternative and is super easy and convenient to use (and customize).

Here's is its (succinct and precise) description from GitHub;

HTTPie (pronounced aych-tee-tee-pie) is a command line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible.

It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.

The documentation around authentication should give you enough pointers to solve your problem(s). Of course, all of the answers above are accurate as well, and provide different ways of accomplishing the same task.

Just so you do NOT have to move away from Stack Overflow, here's what it offers in a nutshell.

Basic auth:_x000D_
_x000D_
$ http -a username:password example.org_x000D_
Digest auth:_x000D_
_x000D_
$ http --auth-type=digest -a username:password example.org_x000D_
With password prompt:_x000D_
_x000D_
$ http -a username example.org

You should chain the replace() together instead of assigning the result and replacing again.

var strMessage1 = document.getElementById("element1") ;
strMessage1.innerHTML = strMessage1.innerHTML
                        .replace(/aaaaaa./g,'<a href=\"http://www.google.com/')
                        .replace(/.bbbbbb/g,'/world\">Helloworld</a>');

See DEMO.

There are a few possible ways to do this:

• Set the environment variable PYTHONPATH to a colon-separated list of directories to search for imported modules.
• In your program, use sys.path.append('/path/to/search') to add the names of directories you want Python to search for imported modules. sys.path is just the list of directories Python searches every time it gets asked to import a module, and you can alter it as needed (although I wouldn't recommend removing any of the standard directories!). Any directories you put in the environment variable PYTHONPATH will be inserted into sys.path when Python starts up.
• Use site.addsitedir to add a directory to sys.path. The difference between this and just plain appending is that when you use addsitedir, it also looks for .pth files within that directory and uses them to possibly add additional directories to sys.path based on the contents of the files. See the documentation for more detail.

Which one of these you want to use depends on your situation. Remember that when you distribute your project to other users, they typically install it in such a manner that the Python code files will be automatically detected by Python's importer (i.e. packages are usually installed in the site-packages directory), so if you mess with sys.path in your code, that may be unnecessary and might even have adverse effects when that code runs on another computer. For development, I would venture a guess that setting PYTHONPATH is usually the best way to go.

However, when you're using something that just runs on your own computer (or when you have nonstandard setups, e.g. sometimes in web app frameworks), it's not entirely uncommon to do something like

import sys
from os.path import dirname
sys.path.append(dirname(__file__))

You can use this drawable xml and set as background to cardview :

    <stroke android:width="1dp"
        android:color="#ff000000"
        />

    <padding android:left="1dp"
        android:top="1dp"
        android:right="1dp"
        android:bottom="1dp"
        />

    <corners 
        android:topLeftRadius="7dp"
        android:topRightRadius="7dp"/>
</shape>

find MyDir -iname "*.[j][p][g]"

Having the .htaccess file on the root folder, add this line. Make sure to delete all other useless rules you tried before:

Options -Indexes

Or try:

Options All -Indexes

For me, I go to \eclipse\configuration.settings\org.eclipse.core.net.prefs set the property systemProxiesEnabled to true manually and restart eclipse.

When you see "Verify return code: 19 (self signed certificate in certificate chain)", then, either the servers is really trying to use a self-signed certificate (which a client is never going to be able to verify), or OpenSSL hasn't got access to the necessary root but the server is trying to provide it itself (which it shouldn't do because it's pointless - a client can never trust a server to supply the root corresponding to the server's own certificate).

Again, adding -showcerts will help you diagnose which.

I believe it is -- when you are working with JS strings.

If you are generating HTML, though, you will have to use <br /> tags (not \n, as you're not dealing with JS anymore)

Addition:

When using the MySQL client library, then you should prevent a conversion back to your connection's default charset. (see mysql_set_character_set()[1])

In this case, use an additional cast to binary:

SELECT column1, CAST(CONVERT(column2 USING utf8) AS binary)
FROM my_table
WHERE my_condition;

Otherwise, the SELECT statement converts to utf-8, but your client library converts it back to a (potentially different) default connection charset.

If after the installation curl-dev luarocks does not see the headers:

find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h

luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/

This query was very useful for me. It shows all values that don't have any matches

select FK_column from FK_table
WHERE FK_column NOT IN
(SELECT PK_column from PK_table)

I like select2, it's feature-rich and nice and active. Particularly like the diacritic search feature.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

This can be solved with an assignment tag:

from django import template

register = template.Library()

@register.assignment_tag
def query(qs, **kwargs):
    """ template tag which allows queryset filtering. Usage:
          {% query books author=author as mybooks %}
          {% for book in mybooks %}
            ...
          {% endfor %}
    """
    return qs.filter(**kwargs)

Maybe try this:

<%= link_to "Add to cart", 
            :controller => "car", 
            :action => "add_to_cart", 
            :car => car.attributes %>

But I'd really like to see where the car object is getting setup for this page (i.e., the rest of the view).

Most of the answers here are on the right track. However, a row is not a tuple. Tuples* are unordered sets of known values with names. Thus, the following tuples are the same thing (I'm using an imaginary tuple syntax since a relational tuple is largely a theoretical construct):

(x=1, y=2, z=3)
(z=3, y=2, x=1)
(y=2, z=3, x=1)

...assuming of course that x, y, and z are all integers. Also note that there is no such thing as a "duplicate" tuple. Thus, not only are the above equal, they're the same thing. Lastly, tuples can only contain known values (thus, no nulls).

A row** is an ordered set of known or unknown values with names (although they may be omitted). Therefore, the following comparisons return false in SQL:

(1, 2, 3) = (3, 2, 1)
(3, 1, 2) = (2, 1, 3)

Note that there are ways to "fake it" though. For example, consider this INSERT statement:

INSERT INTO point VALUES (1, 2, 3)

Assuming that x is first, y is second, and z is third, this query may be rewritten like this:

INSERT INTO point (x, y, z) VALUES (1, 2, 3)

Or this:

INSERT INTO point (y, z, x) VALUES (2, 3, 1)

...but all we're really doing is changing the ordering rather than removing it.

And also note that there may be unknown values as well. Thus, you may have rows with unknown values:

(1, 2, NULL) = (1, 2, NULL)

...but note that this comparison will always yield UNKNOWN. After all, how can you know whether two unknown values are equal?

And lastly, rows may be duplicated. In other words, (1, 2) and (1, 2) may compare to be equal, but that doesn't necessarily mean that they're the same thing.

If this is a subject that interests you, I'd highly recommend reading SQL and Relational Theory: How to Write Accurate SQL Code by CJ Date.

* Note that I'm talking about tuples as they exist in the relational model, which is a bit different from mathematics in general.

**And just in case you're wondering, just about everything in SQL is a row or table. Therefore, (1, 2) is a row, while VALUES (1, 2) is a table (with one row).

UPDATE: I've expanded a little bit on this answer in a blog post here.

Try replacing apt-get with yum as Amazon Linux based AMI uses the yum command instead of apt-get.

The best solution would be to do these steps :

1. Delete the file called - V2__create_shipwreck.sql, clean and build the project again.

2. Run the project again, login into h2 and delete the table called "schema_version".

   drop table schema_version;

3. Now make V2__create_shipwreck.sql file with ddl and rerun the project again.

4. Do remember this, add version 4.1.2 for flyway-core in pom.xml like

   <dependency>
       <groupId>org.flywaydb</groupId>
       <artifactId>flyway-core</artifactId>
       <version>4.1.2</version>
   </dependency>
   

It should work now. Hope this will help.

Shouldn't be hard to test, create a function that switches or ifelse's between 5 numbers, throw a rand(1,5) into that function and loop that a few times while timing it.

Check out this w3schools page about "HTML URL Encoding Reference": https://www.w3schools.com/tags/ref_urlencode.asp

for / you would escape with %2F

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings] "ProxySettingsPerUser"=dword:00000000

Why not this:

CREATE PROCEDURE SP_Reporting(IN tablename VARCHAR(20))
BEGIN
     IF tablename IS NOT NULL THEN
          #proceed the code
     END IF;
     # Do nothing otherwise
END;

The following may help (study the impacts of disable-verity first):

You can use JavaScript to prompt you:

Found this here - Example

<script>
function confirmDelete(delUrl) {
  if (confirm("Are you sure you want to delete")) {
   document.location = delUrl;
  }
}
</script>

<a href="javascript:confirmDelete('delete.page?id=1')">Delete</a>

Another way

<a href="delete.page?id=1" onclick="return confirm('Are you sure you want to delete?')">Delete</a> 

Warning: This JavaScript will not stop the records from being deleted if they just navigate to the final url - delete.page?id=1 in their browser

With Typescript 2.1+, use Partial < T > instead of making your interface properties optional.

export interface Props {
    obj: Model,
    a: boolean
    b: boolean
}

public static defaultProps: Partial<Props> = {
    a: true
};

Yet another reason (not for this case, but maybe it'll save some nerves for someone) is that in PHP 5.5 short open tags <? phpinfo(); ?> are disabled by default.

So the PHP interpreter would process code within short tags as plain text. In previous versions PHP this feature was enable by default. So the new behaviour can be a little bit mysterious.

Is that an actual compiler error or a Code Analysis error? Some times the code analysis can be a bit sketchy and report non-valid errors.

To turn off code analysis for the project, right click on your project in the Project Explorer, click on Properties, then go to the C/C++ General tab, then Code Analysis. Then click on "Use Project Settings" and disable the ones that you do not wish for.

Also, are you sure you are compiling with the C++11 compiler?

Change the window name in your two different calls:

function popitup(url,windowName) {
       newwindow=window.open(url,windowName,'height=200,width=150');
       if (window.focus) {newwindow.focus()}
       return false;
     }

windowName must be unique when you open a new window with same url otherwise the same window will be refreshed.

None of the answers above show a concrete example using massive arrays populated by non-numeric members. Here is an example using an array generated by explode() on a large .txt file (262MB in my use case):

<?php

ini_set('memory_limit','1000M');

echo "Starting memory usage: " . memory_get_usage() . "<br>";

$path = './file.txt';
$content = file_get_contents($path);

foreach(explode("\n", $content) as $ex) {
    $ex = trim($ex);
}

echo "Final memory usage: " . memory_get_usage();

The output was:

Starting memory usage: 415160
Final memory usage: 270948256

Now compare that to a similar script, using the yield keyword:

<?php

ini_set('memory_limit','1000M');

echo "Starting memory usage: " . memory_get_usage() . "<br>";

function x() {
    $path = './file.txt';
    $content = file_get_contents($path);
    foreach(explode("\n", $content) as $x) {
        yield $x;
    }
}

foreach(x() as $ex) {
    $ex = trim($ex);
}

echo "Final memory usage: " . memory_get_usage();

The output for this script was:

Starting memory usage: 415152
Final memory usage: 415616

Clearly memory usage savings were considerable (?MemoryUsage -----> ~270.5 MB in first example, ~450B in second example).

The following captures stdout and stderr of the process in a single variable. It is Python 2 and 3 compatible:

from subprocess import check_output, CalledProcessError, STDOUT

command = ["ls", "-l"]
try:
    output = check_output(command, stderr=STDOUT).decode()
    success = True 
except CalledProcessError as e:
    output = e.output.decode()
    success = False

If your command is a string rather than an array, prefix this with:

import shlex
command = shlex.split(command)

hg rollback is what you want.

In TortoiseHg, the hg rollback is accomplished in the commit dialog. Open the commit dialog and select "Undo".

Notification or data message can be sent to firebase base cloud messaging server using FCM HTTP v1 API endpoint. https://fcm.googleapis.com/v1/projects/zoftino-stores/messages:send.

You need to generate and download private key of service account using Firebase console and generate access key using google api client library. Use any http library to post message to above end point, below code shows posting message using OkHTTP. You can find complete server side and client side code at firebase cloud messaging and sending messages to multiple clients using fcm topic example

If a specific client message needs to sent, you need to get firebase registration key of the client, see sending client or device specific messages to FCM server example

String SCOPE = "https://www.googleapis.com/auth/firebase.messaging";
String FCM_ENDPOINT
     = "https://fcm.googleapis.com/v1/projects/zoftino-stores/messages:send";

GoogleCredential googleCredential = GoogleCredential
    .fromStream(new FileInputStream("firebase-private-key.json"))
    .createScoped(Arrays.asList(SCOPE));
googleCredential.refreshToken();
String token = googleCredential.getAccessToken();



final MediaType mediaType = MediaType.parse("application/json");

OkHttpClient httpClient = new OkHttpClient();

Request request = new Request.Builder()
    .url(FCM_ENDPOINT)
    .addHeader("Content-Type", "application/json; UTF-8")
    .addHeader("Authorization", "Bearer " + token)
    .post(RequestBody.create(mediaType, jsonMessage))
    .build();


Response response = httpClient.newCall(request).execute();
if (response.isSuccessful()) {
    log.info("Message sent to FCM server");
}

I created this simple function to help me. This makes my calls a lot easier to read that having inline an Get-WmiObject, Where-Object statements, etc.

function GetDiskSizeInfo($drive) {
    $diskReport = Get-WmiObject Win32_logicaldisk
    $drive = $diskReport | Where-Object { $_.DeviceID -eq $drive}

    $result = @{
        Size = $drive.Size
        FreeSpace = $drive.Freespace
    }
    return $result
}

$diskspace = GetDiskSizeInfo "C:"
write-host $diskspace.FreeSpace " " $diskspace.Size

I agree partly with Ed Staub. Gradle definitely is more powerful compared to maven and provides more flexibility long term.

After performing an evaluation to move from maven to gradle, we decided to stick to maven itself for two issues we encountered with gradle ( speed is slower than maven, proxy was not working ) .

You can't create tags with Dockerfiles but you can create multiple tags on your images via the command line.

Use this to list your image ids:

$ docker images

Then tag away:

$ docker tag 9f676bd305a4 ubuntu:13.10
$ docker tag 9f676bd305a4 ubuntu:saucy
$ docker tag eb601b8965b8 ubuntu:raring
...

It's probably because you are directly or indirectly through a library call accessing a NULL pointer. In this particular case, it looks like you've jumped to a NULL address, which is a b bit hairier.

In my experience, the easiest way to track these down are to run it with a debugger, and dump a stack trace.

Alternatively, you can do it "by hand" and add lots of logging until you can track down exactly which function (and possibly LOC) this violation occurred in.

Take a look at Stack Tracer, which might help you improve your debugging.

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

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

There are two operators in Python for the "not equal" condition -

a.) != If values of the two operands are not equal, then the condition becomes true. (a != b) is true.

b.) <> If values of the two operands are not equal, then the condition becomes true. (a <> b) is true. This is similar to the != operator.

You should use g++, not gcc, to compile C++ programs.

For this particular program, I just typed

make avishay

and let make figure out the rest. Gives your executable a decent name, too, instead of a.out.

It is slightly similar to the answer by fab but not exactly the same.

The singleton contract does not require that we be able to call the constructor multiple times. As a singleton should be created once and once only, shouldn't it be seen to be created just once? "Spoofing" the constructor arguably impairs legibility.

So my suggestion is just this:

class Elvis():
    def __init__(self):
        if hasattr(self.__class__, 'instance'):
            raise Exception()
        self.__class__.instance = self
        # initialisation code...

    @staticmethod
    def the():
        if hasattr(Elvis, 'instance'):
            return Elvis.instance
        return Elvis()

This does not rule out the use of the constructor or the field instance by user code:

if Elvis() is King.instance:

... if you know for sure that Elvis has not yet been created, and that King has.

But it encourages users to use the the method universally:

Elvis.the().leave(Building.the())

To make this complete you could also override __delattr__() to raise an Exception if an attempt is made to delete instance, and override __del__() so that it raises an Exception (unless we know the program is ending...)

Further improvements

My thanks to those who have helped with comments and edits, of which more are welcome. While I use Jython, this should work more generally, and be thread-safe.

try:
    # This is jython-specific
    from synchronize import make_synchronized
except ImportError:
    # This should work across different python implementations
    def make_synchronized(func):
        import threading
        func.__lock__ = threading.Lock()

        def synced_func(*args, **kws):
            with func.__lock__:
                return func(*args, **kws)

        return synced_func

class Elvis(object): # NB must be subclass of object to use __new__
    instance = None

    @classmethod
    @make_synchronized
    def __new__(cls, *args, **kwargs):
        if cls.instance is not None:
            raise Exception()
        cls.instance = object.__new__(cls, *args, **kwargs)
        return cls.instance

    def __init__(self):
        pass
        # initialisation code...

    @classmethod
    @make_synchronized
    def the(cls):
        if cls.instance is not None:
            return cls.instance
        return cls()

Points of note:

1. If you don't subclass from object in python2.x you will get an old-style class, which does not use __new__
2. When decorating __new__ you must decorate with @classmethod or __new__ will be an unbound instance method
3. This could possibly be improved by way of use of a metaclass, as this would allow you to make the a class-level property, possibly renaming it to instance

In my case, I had to change the cell padding of an element that contained an input checkbox for a table that's being dynamically rendered with DataTables:

<td class="dt-center">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

After implementing the following line code within the initComplete function I was able to produce the correct padding, which fixed the rows from being displayed with an abnormally large height

 $('tbody td:has(input.a)').css('padding', '0px');

Now, you can see that the correct styles are being applied to the parent element:

<td class=" dt-center" style="padding: 0px;">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

Essentially, this answer is an extension of @KP's answer, but the more collaboration of implementing this the better. In summation, I hope this helps someone else because it works! Lastly, thank you so much @KP for leading me in the right direction!

I upgraded mac os to macOS High Sierra - 10.13.3 and faced a similar issue while trying to install watchman (with command - brew install watchman).

ran the command: xcode-select --install, then ran "brew install watchman" - Everything works fine!

I think your first approach to adding members conditionally is perfectly fine. I don't really agree with not wanting to have a member b of a with a value of undefined. It's simple enough to add an undefined check with usage of a for loop with the in operator. But anyways, you could easily write a function to filter out undefined members.

var filterUndefined = function(obj) {
  var ret = {};
  for (var key in obj) {
    var value = obj[key];
    if (obj.hasOwnProperty(key) && value !== undefined) {
      ret[key] = value;
    }
  }
  return ret;
};

var a = filterUndefined({
  b: (conditionB? 5 : undefined),
  c: (conditionC? 5 : undefined),
  d: (conditionD? 5 : undefined),
  e: (conditionE? 5 : undefined),
  f: (conditionF? 5 : undefined),
  g: (conditionG? 5 : undefined),
});

You could also use the delete operator to edit the object in place.

In CSS you need to use a Unicode escape sequence in place of HTML Entities. This is based on the hexadecimal value of a character.

I found that the easiest way to convert symbol to their hexadecimal equivalent is, such as from ▾ (▾) to \25BE is to use the Microsoft calculator =)

Yes. Enable programmers mode, turn on the decimal system, enter 9662, then switch to hex and you'll get 25BE. Then just add a backslash \ to the beginning.

pyspark.sql.Column.contains() is only available in pyspark version 2.2 and above.

df.where(df.location.contains('google.com'))

Initially starting with a pyspark dataframes - I got type conversion errors (when converting to pandas df's and then appending to csv) given the schema/column types in my pyspark dataframes

Solved the problem by forcing all columns in each df to be of type string and then appending this to csv as follows:

with open('testAppend.csv', 'a') as f:
    df2.toPandas().astype(str).to_csv(f, header=False)

Removed and added back in the table using Scaffold-DbContext and the error went away

Instructions for editing your PYTHONPATH or fixing import resolution problems for code inspection are as follows:

1. Open Preferences (On a Mac the keyboard short cut is ?,).

2. Look for Project Structure in the sidebar on the left under Project: Your Project Name

3. Add or remove modules on the right sidebar

EDIT: I have updated this screen shot for PyCharm 4.5

The code below resolved the issue

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls Or SecurityProtocolType.Ssl3

Create a comparator which accepts the compare mode in its constructor and pass different modes for different scenarios based on your requirement

public class RecipeComparator implements Comparator<Recipe> {

public static final int COMPARE_BY_ID = 0;
public static final int COMPARE_BY_NAME = 1;

private int compare_mode = COMPARE_BY_NAME;

public RecipeComparator() {
}

public RecipeComparator(int compare_mode) {
    this.compare_mode = compare_mode;
}

@Override
public int compare(Recipe o1, Recipe o2) {
    switch (compare_mode) {
    case COMPARE_BY_ID:
        return o1.getId().compareTo(o2.getId());
    default:
        return o1.getInputRecipeName().compareTo(o2.getInputRecipeName());
    }
}

}

Actually for numbers you need to handle them separately check below

public static void main(String[] args) {
    String string1 = "1";
    String string2 = "2";
    String string11 = "11";

    System.out.println(string1.compareTo(string2)); 
    System.out.println(string2.compareTo(string11));// expected -1 returns 1
   // to compare numbers you actually need to do something like this

    int number2 = Integer.valueOf(string1);
    int number11 = Integer.valueOf(string11);

    int compareTo = number2 > number11 ? 1 : (number2 < number11 ? -1 : 0) ;
    System.out.println(compareTo);// prints -1
}

Note that if you have committed a bunch of changes in various submodules, you can (or will be soon able to) push everything in one go (ie one push from the parent repo), with:

git push --recurse-submodules=on-demand

git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

--recurse-submodules=<check|on-demand|no>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

This worked for me.

   `sudo apt-get install libjpeg-dev`

You can use this plugin, but for printing purpose i have added some code like <button onclick="window.print();">Print</button> and for saving image <button onclick="savePhoto();">Save Picture</button>

     function savePhoto() {
     var canvas = document.getElementById("canvas");
     var img    = canvas.toDataURL("image/png");
     window.location = img;}

I don't know if there's any solution to do this in a database-agnostic way, since you most likely will need some form of string manipulation, and those are typically different between vendors.

For SQL Server 2005 and up, you could use:

SELECT
     r.ID, r.Name,
     Resources = STUFF(
       (SELECT ','+a.Name
        FROM dbo.Applications a
        INNER JOIN dbo.ApplicationsResources ar ON ar.app_id = a.id
        WHERE ar.resource_id = r.id
        FOR XML PATH('')), 1, 1, '')
FROM
     dbo.Resources r

It uses the SQL Server 2005 FOR XML PATH construct to list the subitems (the applications for a given resource) as a comma-separated list.

SELECT id, 
       IF(type = 'P', amount, amount * -1) as amount
FROM report

See http://dev.mysql.com/doc/refman/5.0/en/control-flow-functions.html.

Additionally, you could handle when the condition is null. In the case of a null amount:

SELECT id, 
       IF(type = 'P', IFNULL(amount,0), IFNULL(amount,0) * -1) as amount
FROM report

The part IFNULL(amount,0) means when amount is not null return amount else return 0.

If you don't want something bloated like jQuery UI, try my custom animations: https://github.com/yckart/jquery-custom-animations

For you, blindLeftToggle and blindRightToggle is the appropriate choice.

http://jsfiddle.net/ARTsinn/65QsU/

<form name="add" method="post">
     <p>Age:</p>
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     </select>
     <input type="submit" name="submit"/>
</form>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

}

copy the column paste it into notepad copy it again paste special as Text

Avoid /etc/*release* files and run this command instead, it is far more reliable and gives more details:

rpm -qia '*release*'

The settings.xml file is not created by itself, you need to manually create it. Here is a sample:

      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0

Use /bin/sh. Create a small shell script that sets the variables, and then parse the template using the shell itself. Like so (edit to handle newlines correctly):

Right click and open SVN Repo-browser:

Right click on Trunk (working copy) and choose Copy to...:

Input the respective branch's name/path:

Click OK, type the respective log message, and click OK.

Remember that ConfigurationManager uses only one app.config - one that is in startup project.

If you put some app.config to a solution A and make a reference to it from another solution B then if you run B, app.config from A will be ignored.

So for example unit test project should have their own app.config.

Yes, quite straight forward:

Private _name As String

Public Property Name() As String
    Get
        Return _name
    End Get
    Private Set(ByVal value As String)
        _name = value
    End Set
End Property

I needed to enable the JUnit plugin, after I linked my project with the jar files.

To enable the JUnit plugin, go to File->Settings, type "JUnit" in the search bar, and under "Plugins," check "JUnit.

vikingsteve's advice above will probably get the libraries linked right. Otherwise, open File->Project Structure, go to Libraries, hit the plus, and then browse to

C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 14.1.1\lib\

and add these jar files:

hamcrest-core-1.3.jar
junit-4.11.jar 
junit.jar 

I guess I found a simpler solution

temp1 = pd.melt(df1, id_vars=["location"], var_name='Date', value_name='Value')
temp2 = pd.melt(df1, id_vars=["name"], var_name='Date', value_name='Value')

Concat whole temp1 with temp2's column name

temp1['new_column'] = temp2['name']

You now have what you asked for.

Try this:

Dim Lastrow As Integer
Lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row

Range("A2:L" & Lastrow).Select

Let's pretend that the value of Lastrow is 50. When you use the following:

Range("A2:L2" & Lastrow).Select

Then it is selecting a range from A2 to L250.

If you would like to handle quotes:

sudo -s -- <<EOF
id
pwd
echo "Done."
EOF

I was also facing the same issue and resolved it after installing the following dependency:

sudo apt-get install lib32z1-dev

Yet another option would be:

SELECT * FROM mytable
 WHERE TRUNC(mydate, 'YEAR') = TRUNC(SYSDATE, 'YEAR');

You could do it like this:

 iterations = 10
 variables = 2

 output <- matrix(ncol=variables, nrow=iterations)

 for(i in 1:iterations){
  output[i,] <- runif(2)

 }

 output

and then turn it into a data.frame

 output <- data.frame(output)
 class(output)

what this does:

1. create a matrix with rows and columns according to the expected growth
2. insert 2 random numbers into the matrix
3. convert this into a dataframe after the loop has finished.

Inline:

<select 
onchange="var val = this.options[this.selectedIndex].value;
this.form.color[1].style.display=(val=='others')?'block':'none'">

I used to do this

In the head (give the select an ID):

window.onload=function() {
  var sel = document.getElementById('color');
  sel.onchange=function() {
    var val = this.options[this.selectedIndex].value;
    if (val == 'others') {
      var newOption = prompt('Your own color','');
      if (newOption) {
        this.options[this.options.length-1].text = newOption;
        this.options[this.options.length-1].value = newOption;
        this.options[this.options.length] = new Option('other','other');
      }
    }
  }
}

HTML : Pass the whole body inside on click

div class="calculate" id="calculate">
            <div class="button" id="button" onclick="myCode(this.body)"> CALCULATE ! </div>
        </div>

Then write the JavaScript code inside the function "myCode()"

function myCode()
{
    var bill = document.getElementById("currency").value ;

    var people_count = document.getElementById("number1").value;
    var select_value = document.getElementById("select").value;

    var calculate = document.getElementById("calculate");

    calculate.addEventListener("click" ,function()
    {
        console.log(bill);
        console.log(people_count);
        console.log(select_value);
    });
}

you will get your values I am using visual studio code editor

for Lat,Long in zip(Latitudes, Longitudes):

For intellij console the 0x08 character worked for me!

System.out.print((char) 8);

If you have an array like

a = [[1, 2], [2, 3], [3, 4]]

Then you extract the first column like that:

[row[0] for row in a]

So the result looks like this:

[1, 2, 3]

most editors support save as ‘Unicode’ encoding actually.

This is an unfortunate misnaming perpetrated by Windows.

Because Windows uses UTF-16LE encoding internally as the memory storage format for Unicode strings, it considers this to be the natural encoding of Unicode text. In the Windows world, there are ANSI strings (the system codepage on the current machine, subject to total unportability) and there are Unicode strings (stored internally as UTF-16LE).

This was all devised in the early days of Unicode, before we realised that UCS-2 wasn't enough, and before UTF-8 was invented. This is why Windows's support for UTF-8 is all-round poor.

This misguided naming scheme became part of the user interface. A text editor that uses Windows's encoding support to provide a range of encodings will automatically and inappropriately describe UTF-16LE as “Unicode”, and UTF-16BE, if provided, as “Unicode big-endian”.

(Other editors that do encodings themselves, like Notepad++, don't have this problem.)

If it makes you feel any better about it, ‘ANSI’ strings aren't based on any ANSI standard, either.

Use like below:

  yourFunc(input: any):Observable<string> {
var requestHeader = { headers: new HttpHeaders({ 'Content-Type': 'text/plain', 'No-Auth': 'False' })};
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.post<string>(this.yourBaseApi+ '/do-api', input, { headers, responseType: 'text' as 'json'  });

}

Just change the SqlCommand.CommandText instead of creating a new SqlCommand every time. There is no need to close and reopen the connection.

// Create the first command and execute
var command = new SqlCommand("<SQL Command>", myConnection);
var reader = command.ExecuteReader();

// Change the SQL Command and execute
command.CommandText = "<New SQL Command>";
command.ExecuteNonQuery();

I'd go with the default arguments, especially since C++ doesn't let you chain constructors (so you end up having to duplicate the initialiser list, and possibly more, for each overload).

That said, there are some gotchas with default arguments, including the fact that constants may be inlined (and thereby become part of your class' binary interface). Another to watch out for is that adding default arguments can turn an explicit multi-argument constructor into an implicit one-argument constructor:

class Vehicle {
public:
  Vehicle(int wheels, std::string name = "Mini");
};

Vehicle x = 5;  // this compiles just fine... did you really want it to?

In your Gem file, write

gem 'execjs'
gem 'therubyracer'

and then run

bundle install

Everything works fine for me :)

we can do it in more easy way like by adding a function on button and on click we call that function for append.

<div id="Content">
<button id="Add" onclick="append();">Add Text</button>
</div> 
<script type="text/javascript">
function append()
{
$('<p>Text</p>').appendTo('#Content');
}
</script>

You will not write code into a static block that needs to be invoked anywhere in your program. If the purpose of the code is to be invoked then you must place it in a method.

You can write static initializer blocks to initialize static variables when the class is loaded but this code can be more complex..

A static initializer block looks like a method with no name, no arguments, and no return type. Since you never call it it doesn't need a name. The only time its called is when the virtual machine loads the class.

We can simply pass the output of python inbuilt print function to a file after opening the file with the append option by using just two lines of code:

with open('filename.txt', 'a') as file:
    print('\nThis printed data will store in a file', file=file)

Hope this may resolve the issue...

Note: this code works with python3 however, python2 is not being supported currently.

Why don't you run TOP and use the options to sort by other metrics, other than PID? Like, highest used PID from the CPU/MEM?

top -o cpu <---sorts all processes by CPU Usage

In general, i.e. unlimited decimal places:

^-?(([1-9]\d*)|0)(.0*[1-9](0*[1-9])*)?$

Tips from 2020:

From Flask 1.0, it defaults to enable multiple threads (source), you don't need to do anything, just upgrade it with:

$ pip install -U flask

If you are using flask run instead of app.run() with older versions, you can control the threaded behavior with a command option (--with-threads/--without-threads):

$ flask run --with-threads

It's same as app.run(threaded=True)

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

Cheers!

This answer might seem silly but I had my laptop's power plan set to something other than High performance (in Windows). I would constantly get out of memory warnings in Visual Studio and things would run a bit slow. After I changed the power setting to High performance, I no longer see any problem.

Differences in SOAP versions

Both SOAP Version 1.1 and SOAP Version 1.2 are World Wide Web Consortium (W3C) standards. Web services can be deployed that support not only SOAP 1.1 but also support SOAP 1.2. Some changes from SOAP 1.1 that were made to the SOAP 1.2 specification are significant, while other changes are minor.

The SOAP 1.2 specification introduces several changes to SOAP 1.1. This information is not intended to be an in-depth description of all the new or changed features for SOAP 1.1 and SOAP 1.2. Instead, this information highlights some of the more important differences between the current versions of SOAP.

The changes to the SOAP 1.2 specification that are significant include the following updates: SOAP 1.1 is based on XML 1.0. SOAP 1.2 is based on XML Information Set (XML Infoset). The XML information set (infoset) provides a way to describe the XML document with XSD schema. However, the infoset does not necessarily serialize the document with XML 1.0 serialization on which SOAP 1.1 is based.. This new way to describe the XML document helps reveal other serialization formats, such as a binary protocol format. You can use the binary protocol format to compact the message into a compact format, where some of the verbose tagging information might not be required.

In SOAP 1.2 , you can use the specification of a binding to an underlying protocol to determine which XML serialization is used in the underlying protocol data units. The HTTP binding that is specified in SOAP 1.2 - Part 2 uses XML 1.0 as the serialization of the SOAP message infoset.

SOAP 1.2 provides the ability to officially define transport protocols, other than using HTTP, as long as the vendor conforms to the binding framework that is defined in SOAP 1.2. While HTTP is ubiquitous, it is not as reliable as other transports including TCP/IP and MQ. SOAP 1.2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that might lead to interoperability errors in the absence of the Web Services-Interoperability (WS-I) profiles. The goal is to significantly reduce the chances of interoperability issues between different vendors that use SOAP 1.2 implementations. SOAP with Attachments API for Java (SAAJ) can also stand alone as a simple mechanism to issue SOAP requests. A major change to the SAAJ specification is the ability to represent SOAP 1.1 messages and the additional SOAP 1.2 formatted messages. For example, SAAJ Version 1.3 introduces a new set of constants and methods that are more conducive to SOAP 1.2 (such as getRole(), getRelay()) on SOAP header elements. There are also additional methods on the factories for SAAJ to create appropriate SOAP 1.1 or SOAP 1.2 messages. The XML namespaces for the envelope and encoding schemas have changed for SOAP 1.2. These changes distinguish SOAP processors from SOAP 1.1 and SOAP 1.2 messages and supports changes in the SOAP schema, without affecting existing implementations. Java Architecture for XML Web Services (JAX-WS) introduces the ability to support both SOAP 1.1 and SOAP 1.2. Because JAX-RPC introduced a requirement to manipulate a SOAP message as it traversed through the run time, there became a need to represent this message in its appropriate SOAP context. In JAX-WS, a number of additional enhancements result from the support for SAAJ 1.3.

There is not difine POST AND GET method for particular android....but all here is differance

GET The GET method appends name/value pairs to the URL, allowing you to retrieve a resource representation. The big issue with this is that the length of a URL is limited (roughly 3000 char) resulting in data loss should you have to much stuff in the form on your page, so this method only works if there is a small number parameters.

What does this mean for me? Basically this renders the GET method worthless to most developers in most situations. Here is another way of looking at it: the URL could be truncated (and most likely will be give today's data-centric sites) if the form uses a large number of parameters, or if the parameters contain large amounts of data. Also, parameters passed on the URL are visible in the address field of the browser (YIKES!!!) not the best place for any kind of sensitive (or even non-sensitive) data to be shown because you are just begging the curious user to mess with it.

POST The alternative to the GET method is the POST method. This method packages the name/value pairs inside the body of the HTTP request, which makes for a cleaner URL and imposes no size limitations on the forms output, basically its a no-brainer on which one to use. POST is also more secure but certainly not safe. Although HTTP fully supports CRUD, HTML 4 only supports issuing GET and POST requests through its various elements. This limitation has held Web applications back from making full use of HTTP, and to work around it, most applications overload POST to take care of everything but resource retrieval.

Plain JavaScript modern solution if you don't need IE support (Array.from is not supported in IE).

You can use combination of Set and Array.from.

const arr = [1, 1, 11, 2, 4, 2, 5, 3, 1];_x000D_
const set = new Set(arr);_x000D_
const uniqueArr = Array.from(set);_x000D_
_x000D_
console.log(uniqueArr);

The Set object lets you store unique values of any type, whether primitive values or object references.

The Array.from() method creates a new Array instance from an array-like or iterable object.

Also Array.from() can be replaced with spread operator.

const arr = [1, 1, 11, 2, 4, 2, 5, 3, 1];_x000D_
const set = new Set(arr);_x000D_
const uniqueArr = [...set];_x000D_
_x000D_
console.log(uniqueArr);

This happened to me when I installed Intellij IDEA 2017, go to menu Preferences -> Build, Execution, Deployment -> Debugger and disable the option: "Force Classic VM for JDK 1.3.x and earlier". This works to me.

You can see some reports in SSMS:

Right-click the instance name / reports / standard / top sessions

You can see top CPU consuming sessions. This may shed some light on what SQL processes are using resources. There are a few other CPU related reports if you look around. I was going to point to some more DMVs but if you've looked into that already I'll skip it.

You can use sp_BlitzCache to find the top CPU consuming queries. You can also sort by IO and other things as well. This is using DMV info which accumulates between restarts.

This article looks promising.

Some stackoverflow goodness from Mr. Ozar.

edit: A little more advice... A query running for 'only' 5 seconds can be a problem. It could be using all your cores and really running 8 cores times 5 seconds - 40 seconds of 'virtual' time. I like to use some DMVs to see how many executions have happened for that code to see what that 5 seconds adds up to.

MY SOLUTION!!!!!!! I fixed this problem when I was trying to install business objects. When the installer failed to register .dll's I inputted the MSVCR71.dll into both system32 and sysWOW64 then clicked retry. Installation finished. I did try adding this in before and after install but, install still failed.

If anyone finds themselves in a position where they need to remember set -e or set -x values and be able to restore them, please check out this gist which uses the first array deletion solution to manage it's own stack:

The other answers that recommend using the object explorer and scripting the stored procedure to a new query editor window and the other queries are solid options.

I personally like using the below query to retrieve the stored procedure definition/code in a single row (I'm using Microsoft SQL Server 2014, but looks like this should work with SQL Server 2008 and up)

SELECT definition 
FROM sys.sql_modules 
WHERE object_id = OBJECT_ID('yourSchemaName.yourStoredProcedureName')

More info on sys.sql_modules:

When you say:

c is not None

You are actually checking if c and None reference the same object. That is what the "is" operator does. In python None is a special null value conventionally meaning you don't have a value available. Sorta like null in c or java. Since python internally only assigns one None value using the "is" operator to check if something is None (think null) works, and it has become the popular style. However this does not have to do with the truth value of the set c, it is checking that c actually is a set rather than a null value.

If you want to check if a set is empty in a conditional statement, it is cast as a boolean in context so you can just say:

c = set()
if c:
   print "it has stuff in it"
else:
   print "it is empty"

But if you want it converted to a boolean to be stored away you can simply say:

c = set()
c_has_stuff_in_it = bool(c)

An unofficial 64-bit Windows build is available from Apache Lounge.

As of Spring 4.2.x, you can create custom mapping annotations, using @RequestMapping as a meta-annotation. So:

Is there a way to produce a "composite/inherited/aggregated" annotation with default values for consumes and produces, such that I could instead write something like:

@JSONRequestMapping(value = "/foo", method = RequestMethod.POST)

Yes, there is such a way. You can create a meta annotation like following:

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping(consumes = "application/json", produces = "application/json")
public @interface JsonRequestMapping {
    @AliasFor(annotation = RequestMapping.class, attribute = "value")
    String[] value() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "method")
    RequestMethod[] method() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "params")
    String[] params() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "headers")
    String[] headers() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "consumes")
    String[] consumes() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "produces")
    String[] produces() default {};
}

Then you can use the default settings or even override them as you want:

@JsonRequestMapping(method = POST)
public String defaultSettings() {
    return "Default settings";
}

@JsonRequestMapping(value = "/override", method = PUT, produces = "text/plain")
public String overrideSome(@RequestBody String json) {
    return json;
}

You can read more about AliasFor in spring's javadoc and github wiki.

I finally got it to work.

I'm not sure if the spaces in the path were breaking things but I changed the workspace of my Aptana installation to something without spaces.

Then I uninstalled XAMPP and reinstalled it because I was thinking maybe I made a typo somewhere without noticing and figured I should be working from scratch.

Turns out Windows 7 has a service somewhere that uses port 80 which blocks apache from starting (giving it the -1) error. So I changed the port it listens to port 8080, no more conflict.

Finally I restarted my computer, for some reason XAMPP doesn't like me messing with ini files and just restarting apache wasn't doing the trick.

Anyway, this has been the most frustrating day ever so I really hope my answer ends up helping someone out!

You could also use T-Regx library:

pattern('\D')->remove($c)

T-Regx also:

• Throws exceptions on fail (not false, null or warnings)
• Has automatic delimiters (delimiters are not required!)
• Has a lot cleaner api

just do this:

import numpy as np

a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])

a * b

You create the relationships the other way around; add foreign keys to the Person type to create a Many-to-One relationship:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        Anniversary, on_delete=models.CASCADE)
    address = models.ForeignKey(
        Address, on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person entries.

Anniversary and Address objects will be given a reverse, backwards relationship too; by default it'll be called person_set but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.

Similar setup, identical problem. Some installations would work, but most would start redirecting (http 302) to /Account/Login?ReturnUrl=%2f after a successful login, even though we're not using Forms Authentication. In my case after trying everything else, the solution was to switch the Application Pool Managed Pipeline Mode from from Integrated to Classic, which cleared up the problem immediately.

There is a global configuration using jQuery. This code runs on every global ajax request.

<div id='ajax_loader' style="position: fixed; left: 50%; top: 50%; display: none;">
    <img src="themes/img/ajax-loader.gif"></img>
</div>

<script type="text/javascript">
    jQuery(function ($){
        $(document).ajaxStop(function(){
            $("#ajax_loader").hide();
         });
         $(document).ajaxStart(function(){
             $("#ajax_loader").show();
         });    
    });    
</script>

Here is a demo: http://jsfiddle.net/sd01fdcm/

using System.Windows.Forms;
...
MessageBox.Show("Hello World!");

Did you try cal.getTime()? This gets the date representation.

You might also want to look at the javadoc.

vimdiff. It's great. All you need is a window three feet wide.

Option 1. Using boost library, you can declare the string as below

const boost::string_view helpText = "This is very long help text.\n"
      "Also more text is here\n"
      "And here\n"

// Pass help text here
setHelpText(helpText);

Option 2. If boost is not available in your project, you can use std::string_view() in modern C++.

Getting EXIF data from a JPEG image involves:

1. Seeking to the JPEG markers which mentions the beginning of the EXIF data,. e.g. normally oxFFE1 is the marker inserted while encoding EXIF data, which is a APPlication segment, where EXIF data goes.
2. Parse all the data from say 0xFFE1 to 0xFFE2 . This data would be stream of bytes, in the JPEG encoded file.
3. ASCII equivalent of these bytes would contain various information related to Image Date, Camera Model Name, Exposure etc...

In my opinion, turning off the -e option to your shell is a really bad idea. Eventually one of the commands in your script will fail due to transient conditions like out of disk space or network errors. Without -e Jenkins won't notice and will continue along happily. If you've got Jenkins set up to do deployment, that may result in bad code getting pushed and bringing down your site.

If you have a line in your script where failure is expected, like a grep or a find, then just add || true to the end of that line. That ensures that line will always return success.

If you need to use that exit code, you can either hoist the command into your if statement:

grep foo bar; if [ $? == 0 ]; then ...    -->   if grep foo bar; then ...

Or you can capture the return code in your || clause:

grep foo bar || ret=$?

If you are working with MVC

try doing this in your controller

public function getLatestUsers() {
    header('Content-Type: application/json');
    echo $this->model->getLatestUsers(); // this returns json_encode($somedata, JSON_PRETTY_PRINT)
}

then if you call /getLatestUsers you will get a pretty JSON output ;)

You can Close your super view window

self.view.superview?.window?.close()

Use Location property of the form. Set it to the desired top left point

desired x = (desktop_width - form_witdh)/2

desired y = (desktop_height - from_height)/2

When you work with web page or javascript file you want it to be reloaded every time you change it. You can change settings in IE 8 so the browser will never cache.

Follow this simple steps.

1. Select Tools-> Internet Options.
2. In General tab click on Settings button in Browsing history section.
3. Click on "Every time I visit the webpage" radio button.
4. Click OK button.

Just a few lines of example code to show the difference between numpy.array and numpy.ndarray

Warm up step: Construct a list

a = [1,2,3]

Check the type

print(type(a))

You will get

<class 'list'>

Construct an array (from a list) using np.array

a = np.array(a)

Or, you can skip the warm up step, directly have

a = np.array([1,2,3])

Check the type

print(type(a))

You will get

<class 'numpy.ndarray'>

which tells you the type of the numpy array is numpy.ndarray

You can also check the type by

isinstance(a, (np.ndarray))

and you will get

True

Either of the following two lines will give you an error message

np.ndarray(a)                # should be np.array(a)
isinstance(a, (np.array))    # should be isinstance(a, (np.ndarray))

If you need all the PHP available parameters, use this:

function in_array(needle, haystack, argStrict) {
    var key = '', strict = !!argStrict;
    if (strict) {
        for (key in haystack) {
            if (haystack[key] === needle) {
                return true;
            }
        }
    }
    else {
        for (key in haystack) {
            if (haystack[key] == needle) {
                return true;
            }
        }
    }
    return false;
}

I know this is old but I didn't see anyone mention extending the String prototype.

String.prototype.replaceAll = function(search, replace){
    if(!search || !replace){return this;} //if search entry or replace entry empty return the string
    return this.replace(new RegExp('[' + search + ']', 'g'), replace); //global RegEx search for all instances ("g") of your search entry and replace them all.
};

Instructions for Drupal 8 / FontAwesome 5

Create a YOUR_THEME_NAME_HERE.THEME file and place it in your themes directory (ie. your_site_name/themes/your_theme_name)

Paste this into the file, it is PHP code to find the Search Block and change the value to the UNICODE for the FontAwesome icon. You can find other characters at this link https://fontawesome.com/cheatsheet.

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
}
?>

Open the CSS file of your theme (ie. your_site_name/themes/your_theme_name/css/styles.css) and then paste this in which will change all input submit text to FontAwesome. Not sure if this will work if you also want to add text in the input button though for just an icon it is fine.

Make sure you import FontAwesome, add this at the top of the CSS file

@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

then add this in the CSS

input#edit-submit {
    font-family: 'Font Awesome\ 5 Free';
    background-color: transparent;
    border: 0;  
}

FLUSH ALL CACHES AND IT SHOULD WORK FINE

Add Google Font Effects

If you are using Google Web Fonts as well you can add also add effects to the icon (see more here https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta). You need to import a Google Web Font including the effect(s) you would like to use first in the CSS so it will be

@import url('https://fonts.googleapis.com/css?family=Open+Sans:400,800&effect=3d-float');
@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

Then go back to your .THEME file and add the class for the 3D Float Effect so the code will now add a class to the input. There are different effects available. So just choose the effect you like, change the CSS for the font import and the change the value FONT-EFFECT-3D-FLOAT int the code below to font-effect-WHATEVER_EFFECT_HERE. Note effects are still in Beta and don't work in all browsers so read here before you try it https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
  $form['actions']['submit']['#attributes']['class'][] = 'font-effect-3d-float';
}
?>

It does work with me. Make sure that you append ".txt" next to timeLog. I used it in a simple program opened with Netbeans and it writes the program in the main folder (where builder and src folders are).

I edited ralf's htp code so that it would compile (on gcc, running ubuntu 16.04 lts). It was just a matter of initializing the variables.

    int w = 100; /* Put here what ever width you want */
    int h = 100; /* Put here what ever height you want */
    int red[w][h]; 
    int green[w][h];
    int blue[w][h];


    FILE *f;
    unsigned char *img = NULL;
    int filesize = 54 + 3*w*h;  //w is your image width, h is image height, both int
    if( img )
            free( img );
    img = (unsigned char *)malloc(3*w*h);
    memset(img,0,sizeof(img));
    int x;
    int y;
    int r;
    int g;
    int b;

    for(int i=0; i<w; i++)
    {
            for(int j=0; j<h; j++)
            {
                    x=i; y=(h-1)-j;
                    r = red[i][j]*255;
                    g = green[i][j]*255;
                    b = blue[i][j]*255;
                    if (r > 255) r=255;
                    if (g > 255) g=255;
                    if (b > 255) b=255;
                    img[(x+y*w)*3+2] = (unsigned char)(r);
                    img[(x+y*w)*3+1] = (unsigned char)(g);

            fwrite(bmppad,1,(4-(w*3)%4)%4,f);
    }
    fclose(f);

I would do it like this:

SELECT top(100)* into #tmpFerdeen
FROM Customers

Insert into #tmpFerdeen
SELECT top(100)* 
FROM CustomerEurope

Insert into #tmpFerdeen
SELECT top(100)* 
FROM CustomerAsia

Insert into #tmpFerdeen
SELECT top(100)* 
FROM CustomerAmericas

my css

TR.gray-t {background:#949494;}
h3{
    padding-top:3px;
    font:bold 12px/2px Arial;
}

my html

<TR class='gray-t'>
<TD colspan='3'><h3>KAJANG</h3>

I decrease the 2nd size in font.

padding-top is used to fix the size in IE7.

UPDATE:

Since I was lazy, and didn't fully implement my solution, I searched around and found BlockComment for Xcode, a recently released plugin (June 2017). Don't bother with my solution, this plugin works beautifully, and I highly recommend it.

ORIGINAL ANSWER:

None of the above worked for me on Xcode 7 and 8, so I:

1. Created Automator service using AppleScript
2. Make sure "Output replaces selected text" is checked

3. Enter the following code:

   on run {input, parameters}
   return "/*\n" & (input as string) & "*/"
   end run
   

Now you can access that service through Xcode - Services menu, or by right clicking on the selected block of code you wish to comment, or giving it a shortcut under System Preferences.

But just to be clear, it is bad practice. Its support throughout browsers is shaky, and it's generally not a good idea. But in cases where you really have to use it, there it is.
