[Posted on behalf of fossuser] Thanks to "mu is too short" I was able to fix the bug. Here is my working code has been edited in for those looking for a nice example (since I couldn't find any others online).

This is how I use the nodejs fs.readdir function to recursively search a directory.

const fs = require('fs');
const mime = require('mime-types');
const readdirRecursivePromise = path => {
    return new Promise((resolve, reject) => {
        fs.readdir(path, (err, directoriesPaths) => {
            if (err) {
                reject(err);
            } else {
                if (directoriesPaths.indexOf('.DS_Store') != -1) {
                    directoriesPaths.splice(directoriesPaths.indexOf('.DS_Store'), 1);
                }
                directoriesPaths.forEach((e, i) => {
                    directoriesPaths[i] = statPromise(`${path}/${e}`);
                });
                Promise.all(directoriesPaths).then(out => {
                    resolve(out);
                }).catch(err => {
                    reject(err);
                });
            }
        });
    });
};
const statPromise = path => {
    return new Promise((resolve, reject) => {
        fs.stat(path, (err, stats) => {
            if (err) {
                reject(err);
            } else {
                if (stats.isDirectory()) {
                    readdirRecursivePromise(path).then(out => {
                        resolve(out);
                    }).catch(err => {
                        reject(err);
                    });
                } else if (stats.isFile()) {
                    resolve({
                        'path': path,
                        'type': mime.lookup(path)
                    });
                } else {
                    reject(`Error parsing path: ${path}`);
                }
            }
        });
    });
};
const flatten = (arr, result = []) => {
    for (let i = 0, length = arr.length; i < length; i++) {
        const value = arr[i];
        if (Array.isArray(value)) {
            flatten(value, result);
        } else {
            result.push(value);
        }
    }
    return result;
};

Let's say you have a path called '/database' in your node projects root. Once this promise is resolved, it should spit out an array of every file under '/database'.

readdirRecursivePromise('database').then(out => {
    console.log(flatten(out));
}).catch(err => {
    console.log(err);
});

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

@Ichorus's answer is correct for views, but if you want to draw rotated rectangles or text, you can do the following in your onDraw (or onDispatchDraw) callback for your view:

(note that theta is the angle from the x axis of the desired rotation, pivot is the Point that represents the point around which we want the rectangle to rotate, and horizontalRect is the rect's position "before" it was rotated)

canvas.save();
canvas.rotate(theta, pivot.x, pivot.y);
canvas.drawRect(horizontalRect, paint);
canvas.restore();

In View use this:

form.field.errors|striptags

for getting validation messages without html

Right click on the stored procedure and select Script Stored Procedure as | CREATE To | New Query Editor Window / Clipboard / File.

You can also do Modify when you right click on the stored procedure.

For multiple procedures at once, click on the Stored Procedures folder, hit F7 to open the Object Explorer Details pane, hold Ctrl and click to select all the ones that you want, and then right click and select Script Stored Procedure as | CREATE To.

Projection: what ever typed in select clause i.e, 'column list' or '*' or 'expressions' that becomes under projection.

*selection:*what type of conditions we are applying on that columns i.e, getting the records that comes under selection.

For example:

  SELECT empno,ename,dno,job from Emp 
     WHERE job='CLERK'; 

in the above query the columns "empno,ename,dno,job" those comes under projection, "where job='clerk'" comes under selection

Use the absolute value function ABS. The syntax is

ABS ( numeric_expression )

The cleanest, most efficient and paradigm-friendly solution in this case is to use a System.Windows.Forms.BindingSource as a proxy between your list of items (datasource) and your DataGridView:

var itemStates = new List<ItemState>();
var bindingSource1 = new System.Windows.Forms.BindingSource { DataSource = itemStates };
dataGridView1.DataSource = bindingSource1;

Then, when adding items, use Add() method of BindingSource instead of your list's Add() method:

for (var i = 0; i < 10; i++)
{
    bindingSource1.Add(new ItemState { Id = i.ToString() });
    System.Threading.Thread.Sleep(500);
}

This way you adding items to your list and notifying DataGridView about those additions with the same line of code. No need to reset DataGridView's DataSource every time you make a change to the list.

It also worth mentioning that you can drop a BindingSource onto your form directly in Visual Studio's Forms Designer and attach it as a data source to your DataGridView there as well, which saves you a line of code in the above example where I'm doing it manually.

The other way around using numpy.where() :

import numpy as np
import pandas as pd

In [800]: df = pd.DataFrame(np.arange(10).reshape(5,2),columns=['c1','c2'])

In [801]: df
Out[801]: 
   c1  c2
0   0   1
1   2   3
2   4   5
3   6   7
4   8   9

In [802]: np.where(df["c1"]==6)
Out[802]: (array([3]),)

In [803]: indices = list(np.where(df["c1"]==6)[0])

In [804]: df.iloc[indices]
Out[804]: 
   c1  c2
3   6   7

In [805]: df.iloc[indices].index
Out[805]: Int64Index([3], dtype='int64')

In [806]: df.iloc[indices].index.tolist()
Out[806]: [3]

A few years late, but here is another alternative.

For x = LBound(arr) To UBound(arr)
    sname = arr(x)  
    If InStr(sname, "Configuration item") Then  
        'Do nothing here, which automatically go to the next iteration
    Else
        'Code to perform the required action
    End If
Next x

This is a feature of C# 4.0, but was not possible without using function overload prior to that version.

Python integers don't have an inherent length or number of significant digits. If you want them to print a specific way, you need to convert them to a string. There are several ways you can do so that let you specify things like padding characters and minimum lengths.

To pad with zeros to a minimum of three characters, try:

length = 1
print(format(length, '03'))

I'm not sure I understand your question. But there are two approaches to making the image invisible...

Pure HTML

<img src="a.gif" style="display: none;" />

Or...

HTML + Javascript

<script type="text/javascript">
document.getElementById("myImage").style.display = "none";
</script>

<img id="myImage" src="a.gif" />

#/bin/bash
# $1 is the file name
# usage: this_script  <filename>
IP_address="xx.xxx.xx.xx"
username="username"
domain=my.ftp.domain
password=password

echo "

 open $IP_address
 USER $username $password
 put $1
 bye
" | ftp -n > ftp_$$.log

            <div style="height:800px; width:240px; border:1px solid #ccc; font:16px/26px Georgia, Garamond, Serif; overflow:auto;">

</TABLE>

DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month)

Note that @sdqali's script will (at least when using Gradle 1.6) ask for the password anytime you invoke any gradle task. Since you only need it when doing gradle assembleRelease (or similar), you could use the following trick:

android {
    ...
    signingConfigs {
        release {
            // We can leave these in environment variables
            storeFile file(System.getenv("KEYSTORE"))
            keyAlias System.getenv("KEY_ALIAS")

            // These two lines make gradle believe that the signingConfigs
            // section is complete. Without them, tasks like installRelease
            // will not be available!
            storePassword "notYourRealPassword"
            keyPassword "notYourRealPassword"
        }
    }
    ...
}

task askForPasswords << {
    // Must create String because System.readPassword() returns char[]
    // (and assigning that below fails silently)
    def storePw = new String(System.console().readPassword("Keystore password: "))
    def keyPw  = new String(System.console().readPassword("Key password: "))

    android.signingConfigs.release.storePassword = storePw
    android.signingConfigs.release.keyPassword = keyPw
}

tasks.whenTaskAdded { theTask -> 
    if (theTask.name.equals("packageRelease")) {
        theTask.dependsOn "askForPasswords"
    }
}

Note that I also had to add the following (under android) to make it work:

buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}

A one-line approach:

var jsonData = Ext.encode(Ext.pluck(store.data.items, 'data'));

Not very pretty, but quite short.

Refer: http://www.wellho.net/mouth/754_tar-jar-war-ear-sar-files.html

tar (tape archives) - Format used is file written in serial units of fileName, fileSize, fileData - no compression. can be huge

Jar (java archive) - compression techniques used - generally contains java information like class/java files. But can contain any files and directory structure

war (web application archives) - similar like jar files only have specific directory structure as per JSP/Servlet spec for deployment purposes

ear (enterprise archives) - similar like jar files. have directory structure following J2EE requirements so that it can be deployed on J2EE application servers. - can contain multiple JAR and WAR files

There's a Microsoft Doc for creating your WCF proxy from the command line .

You can find your local copy of wsdl.exe in a location similar to this: C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools (Learn more here)

In the end your Command should look similar to this:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\wsdl.exe"
 /language:CS /n:"My.Namespace" https://www.example.com/service/wsdl

As your list is an ArrayList, it can be assumed that it is unsorted. Therefore, there is no way to search for your element that is faster than O(n).

If you can, you should think about changing your list into a Set (with HashSet as implementation) with a specific Comparator for your sample class.

Another possibility would be to use a HashMap. You can add your data as Sample (please start class names with an uppercase letter) and use the string you want to search for as key. Then you could simply use

Sample samp = myMap.get(myKey);

If there can be multiple samples per key, use Map<String, List<Sample>>, otherwise use Map<String, Sample>. If you use multiple keys, you will have to create multiple maps that hold the same dataset. As they all point to the same objects, space shouldn't be that much of a problem.

For tomcat you can increase the permGem space by using

 -XX:MaxPermSize=128m

For this you need to create (if not already exists) a file named setenv.sh in tomcat/bin folder and include following line in it

   export JAVA_OPTS="-XX:MaxPermSize=128m"

Using the RESTORE DATABASE command most likely. bak is a common extension used for a database backup file. You'll find documentation for this command on MSDN.

This is for Laravel 5.1 and I am not sure does it work for earlier versions but if somebody search on Google and lands here it might be handy in middleware handle function gets $request parameter:

$request->server->get('SERVER_NAME')

outside of middleware handle method you can access it by helper function request()

request()->server->get('SERVER_NAME')

This is relatively new to C# which makes it easy for us to call the functions with respect to the null or non-null values in method chaining.

old way to achieve the same thing was:

var functionCaller = this.member;
if (functionCaller!= null)
    functionCaller.someFunction(var someParam);

and now it has been made much easier with just:

member?.someFunction(var someParam);

I strongly recommend this doc page.

Neovim and Vim 8.2 support this natively via the :ter[minal] command.

See terminal-window in the docs for details.

If you want to make exceptions, you can apply the following "hack". It requires a user with DELETE and INSERT privilege for mysql.plugin system table.

uninstall plugin validate_password;
SET PASSWORD FOR 'app' = PASSWORD('abcd');
INSTALL PLUGIN validate_password SONAME 'validate_password.so';

Bland security disclaimer: Consider, why you are making your password shorter or easier and perhaps consider replacing it with one that is more complex. However, I understand the "it's 3AM and just needs to work" moments, just make sure you don't build a system of hacks, lest you yourself be hacked

jQuery provides $(window).resize() function by default:

<script type="text/javascript">
// function for resize of div/span elements
var $window = $( window ),
    $rightPanelData = $( '.rightPanelData' )
    $leftPanelData = $( '.leftPanelData' );

//jQuery window resize call/event
$window.resize(function resizeScreen() {
    // console.log('window is resizing');

    // here I am resizing my div class height
    $rightPanelData.css( 'height', $window.height() - 166 );
    $leftPanelData.css ( 'height', $window.height() - 236 );
});
</script> 

Connect to the database, then list the tables:

\c liferay
\dt

That's how I do it anyway.

You can combine those two commands onto a single line, if you prefer:

\c liferay \dt

You can't convert binary data to String. As a solution you can encode binary data and then convert to String. For example, look at this How do you convert binary data to Strings and back in Java?

Make a script

#!/bin/sh
echo $* 1>&2

that would be your tool.

Or make a function if you don't want to have a script in separate file.

Yes. The same notation that works for non-empty dict/set works for empty ones.

Notice the difference between non-empty dict and set literals:

{1: 'a', 2: 'b', 3: 'c'} -- a number of key-value pairs inside makes a dict
{'aaa', 'bbb', 'ccc'} -- a tuple of values inside makes a set

So:

{} == zero number of key-value pairs == empty dict
{*()} == empty tuple of values == empty set

However the fact, that you can do it, doesn't mean you should. Unless you have some strong reasons, it's better to construct an empty set explicitly, like:

a = set()

Performance:

The literal is ~15% faster than the set-constructor (CPython-3.8, 2019 PC, Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz):

>>> %timeit ({*()} & {*()}) | {*()}
214 ns ± 1.26 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

>>> %timeit (set() & set()) | set()
252 ns ± 0.566 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

... and for completeness, Renato Garcia's frozenset proposal on the above expression is some 60% faster!

>>> ? = frozenset()

>>> %timeit (? & ?) | ?
100 ns ± 0.51 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

NB: As ctrueden noticed in comments, {()} is not an empty set. It's a set with 1 element: empty tuple.

This happens to me sometimes, EADDR in use. Typically there is a terminal window hiding out in the background that is still running the app. You can stop process with ctrl+C in the terminal window.

Or, perhaps you are listening to the port multiple times due to copy/pasta =)

The problem is that you mapped your servlet to /register.html and it expects POST method, because you implemented only doPost() method. So when you open register.html page, it will not open html page with the form but servlet that handles the form data.

Alternatively when you submit POST form to non-existing URL, web container will display 405 error (method not allowed) instead of 404 (not found).

To fix:

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

Because you rebased feature on top of the new master, your local feature is not a fast-forward of origin/feature anymore. So, I think, it's perfectly fine in this case to override the fast-forward check by doing git push origin +feature. You can also specify this in your config

git config remote.origin.push +refs/heads/feature:refs/heads/feature

If other people work on top of origin/feature, they will be disturbed by this forced update. You can avoid that by merging in the new master into feature instead of rebasing. The result will indeed be a fast-forward.

You need to make two case labels.

Control will fall through from the first label to the second, so they'll both execute the same code.

You can avoid the loop and cut etc by using:

awk -F ':' '{system("ping " $1);}' config.txt

However it would be better if you post a snippet of your config.txt

Another alternative of the curl-less method above is to use the native stream functions:

• stream_context_create():

  Creates and returns a stream context with any options supplied in options preset.

• stream_get_contents():

  Identical to file_get_contents(), except that stream_get_contents() operates on an already open stream resource and returns the remaining contents in a string, up to maxlength bytes and starting at the specified offset.

A POST function with these can simply be like this:

<?php

function post_request($url, array $params) {
  $query_content = http_build_query($params);
  $fp = fopen($url, 'r', FALSE, // do not use_include_path
    stream_context_create([
    'http' => [
      'header'  => [ // header array does not need '\r\n'
        'Content-type: application/x-www-form-urlencoded',
        'Content-Length: ' . strlen($query_content)
      ],
      'method'  => 'POST',
      'content' => $query_content
    ]
  ]));
  if ($fp === FALSE) {
    return json_encode(['error' => 'Failed to get contents...']);
  }
  $result = stream_get_contents($fp); // no maxlength/offset
  fclose($fp);
  return $result;
}

You could use the following query:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 
            ON table1.id IN (table2.user_one, table2.user_two)
WHERE   table2.user_one IS NULL;

Although, depending on your indexes on table2 you may find that two joins performs better:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 AS t1
            ON table1.id = t1.user_one
        LEFT JOIN table2 AS t2
            ON table1.id = t2.user_two
WHERE   t1.user_one IS NULL
AND     t2.user_two IS NULL;

You can also use Parser() from html-react-parser. I have used the same. Link shared.

If you are using a virtual hosts configuration file, make sure the virtual host in question has the directive AllowOverride All somewhere like this:

<VirtualHost *:80>
        ...
    <Directory "directory/of/your/.htaccess">
        AllowOverride All
    </Directory>
</VirtualHost>

Basically, this states to allow processing of all .htaccess directives.

As to me, i need to caffe to my python path. I can add it's path to the file /home/xy/.bashrc by add

export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH.

to my /home/xy/.bashrc file.

But when I use pycharm, the path is still not in.

So I can add path to PYTHONPATH variable, by run -> edit Configuration.

>>> [int(i) for i in str(12345)]

[1, 2, 3, 4, 5]

It most likely means the hostname can't be resolved.

import socket
socket.getaddrinfo('localhost', 8080)

If it doesn't work there, it's not going to work in the Bottle example. You can try '127.0.0.1' instead of 'localhost' in case that's the problem.

Use the CKEditor method setData():

CKEDITOR.instances[**fieldname**].setData(**your data**)

This will let you read, write and create the file if it don't exist:

f = open('filename.txt','a+')
f = open('filename.txt','r+')

Often used commands:

f.readline() #Read next line
f.seek(0) #Jump to beginning
f.read(0) #Read all file
f.write('test text') #Write 'test text' to file
f.close() #Close file

Found another solution for the same. It will be more helpful.

I open one old Asp.net webform (.Net Framework4.5)solution with Visual Studio 2019, has same issue. The solution quite simple, go to web project's properties-> Web-> checked "Override application root URL" -> assign another port number. Save the solution and run in debug mode again. Problem resolved.

Here's a twist on the solution provided by @Anatoliy.

I needed to generate only light colours (for backgrounds), so I went with three letter (#AAA) format:

function get_random_color() {
    var letters = 'ABCDE'.split('');
    var color = '#';
    for (var i=0; i<3; i++ ) {
        color += letters[Math.floor(Math.random() * letters.length)];
    }
    return color;
}

The easiest way to find a midnight:

Long time = new Date().getTime();
Date date = new Date(time - time % (24 * 60 * 60 * 1000));

Next day:

Date date = new Date(date.getTime() + 24 * 60 * 60 * 1000);

window.onload however they are often the same thing. Similarly body.onload becomes window.onload in IE.

You could convert to string, right?

n = (n + "").split(".");

The default answer is to remove the item from whatever collection you're using as the GridView's DataSource.

If that option is undesirable then I recommend that you use the GridView's RowDataBound event to selectively set the row's (e.Row) Visible property to false.

First we'll consider loops where the number of iterations of the inner loop is independent of the value of the outer loop's index. For example:

 for (i = 0; i < N; i++) {
     for (j = 0; j < M; j++) {
         sequence of statements
      }
  }

The outer loop executes N times. Every time the outer loop executes, the inner loop executes M times. As a result, the statements in the inner loop execute a total of N * M times. Thus, the total complexity for the two loops is O(N2).

You could search for the corresponding key or you could "invert" the dictionary, but considering how you use it, it would be best if you just iterated over key/value pairs in the first place, which you can do with items(). Then you have both directly in variables and don't need a lookup at all:

for key, value in PIX0.items():
    NUM = input("What is the Resolution of %s?"  % key)
    if NUM == value:

You can of course use that both ways then.

Or if you don't actually need the dictionary for something else, you could ditch the dictionary and have an ordinary list of pairs.

We have seen this same behavior in the past. It turned out that, for some crazy reason, if a NullPointerException occurred at the same place in the code multiple times, after a while using Log.error(String, Throwable) would stop including full stack traces.

Try looking further back in your log. You may find the culprit.

EDIT: this bug sounds relevant, but it was fixed so long ago it's probably not the cause.

Using your code with some random data, this would work:

fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)

axs = axs.ravel()

for i in range(10):

    axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)
    axs[i].set_title(str(250+i))

The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).

Easy way to achieve: (Do this in your Javascript)

$("selector").dialog({
    autoOpen: false,
    open: function(event, ui) {   // It'll hide Close button
        $(".ui-dialog-titlebar-close", ui.dialog | ui).hide();
    },
    closeOnEscape: false,        // Do not close dialog on press Esc button
    show: {
        effect: "clip",
        duration: 500
    },
    hide: {
        effect: "blind",
        duration: 200
    },
    ....
});

In Swift use this,

If you wants to have pull to refresh in WebView,

So try this code:

override func viewDidLoad() {
    super.viewDidLoad()
    addPullToRefreshToWebView()
}

func addPullToRefreshToWebView(){
    var refreshController:UIRefreshControl = UIRefreshControl()

    refreshController.bounds = CGRectMake(0, 50, refreshController.bounds.size.width, refreshController.bounds.size.height) // Change position of refresh view
    refreshController.addTarget(self, action: Selector("refreshWebView:"), forControlEvents: UIControlEvents.ValueChanged)
    refreshController.attributedTitle = NSAttributedString(string: "Pull down to refresh...")
    YourWebView.scrollView.addSubview(refreshController)

}

func refreshWebView(refresh:UIRefreshControl){
    YourWebView.reload()
    refresh.endRefreshing()
}

URL url= new URL("http://example.com/query?q=random word £500 bank $");
URI uri = new URI(url.getProtocol(), url.getUserInfo(), IDN.toASCII(url.getHost()), url.getPort(), url.getPath(), url.getQuery(), url.getRef());
String correctEncodedURL=uri.toASCIIString(); 
System.out.println(correctEncodedURL);

Prints

http://example.com/query?q=random%20word%20%C2%A3500%20bank%20$

What is happening here?

1. Split URL into structural parts. Use java.net.URL for it.

2. Encode each structural part properly!

3. Use IDN.toASCII(putDomainNameHere) to Punycode encode the host name!

4. Use java.net.URI.toASCIIString() to percent-encode, NFC encoded unicode - (better would be NFKC!). For more info see: How to encode properly this URL

In some cases it is advisable to check if the url is already encoded. Also replace '+' encoded spaces with '%20' encoded spaces.

Here are some examples that will also work properly

{
      "in" : "http://???????.com/",
     "out" : "http://xn--mgba3gch31f.com/"
},{
     "in" : "http://www.example.com/?/foo",
     "out" : "http://www.example.com/%E2%80%A5/foo"
},{
     "in" : "http://search.barnesandnoble.com/booksearch/first book.pdf", 
     "out" : "http://search.barnesandnoble.com/booksearch/first%20book.pdf"
}, {
     "in" : "http://example.com/query?q=random word £500 bank $", 
     "out" : "http://example.com/query?q=random%20word%20%C2%A3500%20bank%20$"
}

The solution passes around 100 of the testcases provided by Web Plattform Tests.

GNU coreutils has it in lib/base64. It's a little bloated but deals with stuff like EBCDIC. You can also play around on your own, e.g.,

char base64_digit (n) unsigned n; {
  if (n < 10) return n - '0';
  else if (n < 10 + 26) return n - 'a';
  else if (n < 10 + 26 + 26) return n - 'A';
  else assert(0);
  return 0;
}

unsigned char base64_decode_digit(char c) {
  switch (c) {
    case '=' : return 62;
    case '.' : return 63;
    default  :
      if (isdigit(c)) return c - '0';
      else if (islower(c)) return c - 'a' + 10;
      else if (isupper(c)) return c - 'A' + 10 + 26;
      else assert(0);
  }
  return 0xff;
}

unsigned base64_decode(char *s) {
  char *p;
  unsigned n = 0;

  for (p = s; *p; p++)
    n = 64 * n + base64_decode_digit(*p);

  return n;
}

Know ye all persons by these presents that you should not confuse "playing around on your own" with "implementing a standard." Yeesh.

I have built an module for this if you want to add styles based on a condition like this:

multipleStyles(styles.icon, { [styles.iconRed]: true })

https://www.npmjs.com/package/react-native-multiple-styles

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

Is it possible for you to use sudo apt-get install python-seaborn instead? Basically tar.gz is just a zip file containing a setup, so what you want to do is to unzip it, cd to the place where it is downloaded and use gunzip -c seaborn-0.7.0.tar.gz | tar xf - for linux. Change dictionary into the new seaborn unzipped file and execute python setup.py install

Use the :checked selector to determine if a value is selected:

function getRadioValue () {
    if( $('input[name=myradiobutton]:radio:checked').length > 0 ) {
        return $('input[name=myradiobutton]:radio:checked').val();
    }
    else {
        return 0;
    }
}

Update you can call the function above at any time to get the selected value of the radio buttons. You can hook into it on load and then whenever the value changes with the following events:

$(document).ready( function() {
    // Value when you load the page for the first time
    // Will return 0 the first time it's called
    var radio_button_value = getRadioValue();

    $('input[name=myradiobutton]:radio').click( function() {
        // Will get the newly selected value
        radio_button_value = getRadioValue();
    });
}

Tested with Microsoft Excel 2016

A really tested solution.

1 include the class job

2 implement the class to handle the apropiate dispose of excel proces

So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.

 protected void onCreate(Bundle savedInstanceState) {     setContentView(R.layout.my_layout);     Bitmap bitmap = getIntent().getParcelableExtra("image");     ImageView imageView = (ImageView) findViewById(R.id.imageview);     imageView.setImageBitmap(bitmap);  } 

If the table is compressed this will work:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES move nocompress;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

alter table EVAPP_FEES compress;

#! /bin/bash
cat filename | while read LINE; do
    echo $LINE
done

There are only minor error.Use MM instead of mm ,so it will be effective write as below:

 @DateTime.Now.ToString("dd/MM/yyy")

You should install as described here:

pip install image

It works fine with the object literal notation:

var map = { key : { "aaa", "rrr" }, 
            key2: { "bbb", "ppp" } // trailing comma leads to syntax error in IE!
          }

Btw, the common way to instantiate arrays

var array = [];
// directly with values:
var array = [ "val1", "val2", 3 /*numbers may be unquoted*/, 5, "val5" ];

and objects

var object = {};

Also you can do either:

obj.property     // this is prefered but you can also do
obj["property"]  // this is the way to go when you have the keyname stored in a var

var key = "property";
obj[key] // is the same like obj.property

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

Use <f:convertDateTime>. You can nest this in any input and output component. Pattern rules are same as java.text.SimpleDateFormat.

<h:outputText value="#{someBean.dateField}" >

Often times you see failure if the host has not been added or authorized (hence I always manually login as hudson/jenkins for the first connection to github/bitbucket) but that link you included supposedly fixes that.

If the above doesn't work try recopying the key. Make sure its the pub key (ie id_rsa.pub). Maybe you missed some characters?

Try with: format(now(), "yyyy-MM-dd hh:mm:ss")

This regexp works for me:

form\[([^']*?)\]

example:

form[company_details][0][name]
form[company_details][0][common_names][1][title]

output:

Match 1
1.  company_details
Match 2
1.  company_details

    qsrand(QTime::currentTime().msec());
    for (int i = 0; i < length; ++i) {

MyClass.prototype.myMethod = function() {
  MyClass.prototype.myMethod_original.call( this );
  alert( "doing override");
};

myObj = new MyClass();
myObj.myMethod();

an option that worked for me, define the field in the original form as:

forms.CharField(widget = forms.HiddenInput(), required = False)

then when you override it in the new Class it will keep it's place.

To answer the original question: yes, you can access the index value of a row in apply(). It is available under the key name and requires that you specify axis=1 (because the lambda processes the columns of a row and not the rows of a column).

Working example (pandas 0.23.4):

>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
   b  c
a      
1  2  3
4  5  6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
   b  c  index_x10
a                 
1  2  3         10
4  5  6         40

There's a couple of ways you can do this. If the onchange listener is a function set via the element.onchange property and you're not bothered about the event object or bubbling/propagation, the easiest method is to just call that function:

element.onchange();

If you need it to simulate the real event in full, or if you set the event via the html attribute or addEventListener/attachEvent, you need to do a bit of feature detection to correctly fire the event:

if ("createEvent" in document) {
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent("change", false, true);
    element.dispatchEvent(evt);
}
else
    element.fireEvent("onchange");

Building on verified answer, for me this worked best:

ab = pd.concat({k: pd.DataFrame(v).T for k, v in data.items()}, axis=0)
ab.T

You could try a more compact style:

std::string number_in_string;

double number_in_double;

std::ostringstream output;

number_in_string = (dynamic_cast< std::ostringstream*>(&(output << number_in_double <<

std::endl)))->str(); 

For those of you who share my weird fondness of manually editing config files, adding (or modifying) the following would also do the trick.

.git/config (personal config)

[submodule "cookbooks/apt"]
    url = https://github.com/opscode-cookbooks/apt

.gitmodules (committed shared config)

[submodule "cookbooks/apt"]
    path = cookbooks/apt
    url = https://github.com/opscode-cookbooks/apt

See this as well - difference between .gitmodules and specifying submodules in .git/config?

Another simple solution is to use map() as follows:

tensor_shape = map(int, my_tensor.shape)

This converts all the Dimension objects to int

if you are in a activity, assume there is only one root view,you can get it like this.

ViewGroup viewGroup = (ViewGroup) ((ViewGroup) this
        .findViewById(android.R.id.content)).getChildAt(0);

you can then cast it to your real class

or you could using

getWindow().getDecorView();

notice this will include the actionbar view, your view is below the actionbar view

Using the DISTINCT flag will remove duplicate rows.

SELECT DISTINCT
C.Content_ID,
C.Content_Title,
M.Media_Id

FROM tbl_Contents C
LEFT JOIN tbl_Media M ON M.Content_Id = C.Content_Id 
ORDER BY C.Content_DatePublished ASC

Can em.flush() cause any harm when using it within a transaction?

Yes, it may hold locks in the database for a longer duration than necessary.

Generally, When using JPA you delegates the transaction management to the container (a.k.a CMT - using @Transactional annotation on business methods) which means that a transaction is automatically started when entering the method and commited / rolled back at the end. If you let the EntityManager handle the database synchronization, sql statements execution will be only triggered just before the commit, leading to short lived locks in database. Otherwise your manually flushed write operations may retain locks between the manual flush and the automatic commit which can be long according to remaining method execution time.

Notes that some operation automatically triggers a flush : executing a native query against the same session (EM state must be flushed to be reachable by the SQL query), inserting entities using native generated id (generated by the database, so the insert statement must be triggered thus the EM is able to retrieve the generated id and properly manage relationships)

Assuming Nothing Follows Them

If these two div elements are basically your main layout elements, and nothing follows them in the html, then there is a pure HMTL/CSS solution that takes the normal order shown in this fiddle and is able to flip it vertically as shown in this fiddle using one additional wrapper div like so:

HTML

<div class="wrapper flipit">
   <div id="first_div">first div</div>
   <div id="second_div">second div</div>
</div>

CSS

.flipit {
    position: relative;
}
.flipit #first_div {
    position: absolute;
    top: 100%;
    width: 100%;
}

This would not work if elements follow these div's, as this fiddle illustrates the issue if the following elements are not wrapped (they get overlapped by #first_div), and this fiddle illustrates the issue if the following elements are also wrapped (the #first_div changes position with both the #second_div and the following elements). So that is why, depending on your use case, this method may or may not work.

For an overall layout scheme, where all other elements exist inside the two div's, it can work. For other scenarios, it will not.

Just a few suggestions:

• Screenshots might be an easy way, but you'll have to make sure the code in the image is big enough and clear enough to read. (not the whole screenshot, just the relevant part)
• If you can embed html then there are lots of tools to generate syntax highlighted html.

The try/catch socket based solutions , might not yield accurate results (the socket address is "localhost" and in some cases the port could be "occupied" not by the loopback interface and at least on Windows I've seen this test fails i.e. the prot falsely declared as available).

There is a cool library named SIGAR , the following code can hook you up :

Sigar sigar = new Sigar();
int flags = NetFlags.CONN_TCP | NetFlags.CONN_SERVER | NetFlags.CONN_CLIENT;             NetConnection[] netConnectionList = sigar.getNetConnectionList(flags);
for (NetConnection netConnection : netConnectionList) {
   if ( netConnection.getLocalPort() == port )
        return false;
}
return true;

In my case, I want to add a column to a Primary key (column4). I used this script to add column4

ALTER TABLE TableA
DROP CONSTRAINT [PK_TableA]

ALTER TABLE TableA
ADD CONSTRAINT [PK_TableA] PRIMARY KEY (
    [column1] ASC,
    [column2] ASC, 
    [column3] ASC,
    [column4] ASC
)

I would set the maximum size, minimum size and remove the gripper icon of the window.

Set properties (MaximumSize, MinimumSize, and SizeGripStyle):

this.MaximumSize = new System.Drawing.Size(500, 550);
this.MinimumSize = new System.Drawing.Size(500, 550);
this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;

From this page:

Make oldconfig takes the .config and runs it through the rules of the Kconfig files and produces a .config which is consistant with the Kconfig rules. If there are CONFIG values which are missing, the make oldconfig will ask for them.

If the .config is already consistant with the rules found in Kconfig, then make oldconfig is essentially a no-op.

If you were to run make oldconfig, and then run make oldconfig a second time, the second time won't cause any additional changes to be made.

I had the same issue. I tired below solutions but didn’t worked :

1. Clean Project (cmd + shift + k) and even Clean Project Build (cmd + shift + alt + k)
2. Deleted Derived data and Module Cache content

Below workaround to this issue :

1. Move to source code file and write the IBOutlet / IBAction manually (copy paste preferred)

2. Then move to Storyboard file and Open Utilites window
3. Goto Connection Inspector
4. Then Connect the IBOutlet and IBAction written in source file with Interface Builder.

mins = minutes + 1

should be

minutes = minutes + 1

Also,

minutes = 0

needs to be outside of the while loop.

This happened to me as well. For me, Postfix was located at the same server as the PHP script, and the error was happening when I would be using SMTP authentication and smtp.domain.com instead of localhost.

So when I commented out these lines:

$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls";

and set the host to

$mail->Host = "localhost";

instead

$mail->Host = 'smtp.mydomainiuse.com'

and it worked :)

It could be not a problem with a single line of your code.

On some devices (I don't recall if it is in stock Android) the Permission dialog includes a check box labeled "Never ask again". If you click Deny with the box checked then you won't be prompted again for that permission, it will automatically be denied to the app. To revert this, you have to go into Settings -> App -> Permissions and re--enable that perm for the app. Then turn it off to deny it again. You may have to open the app before turning it off again, not sure.

I don't know if your Nexus has it. Maybe worth a try.

I had this problem and tried everything here but it didn't help. Then I noticed that the cord I was using was a little frayed, so I tried a new cord and it worked.

With plans to slowly retire the long-used Objective-C, Apple has introduced a new programming language, called Swift, for designing apps and applications to run on Apple iOS devices and Apple Macintosh computers.

Apple says: "Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works."

Introducing swift

@Resource is often used by high-level objects, defined via JNDI. @Autowired or @Inject will be used by more common beans.

As far as I know, it's not a specification, nor even a convention. It's more the logical way standard code will use these annotations.

I also had this problem, my solution was to have an element above the element i dont want a hover effect on:

.no-hover {_x000D_
  position: relative;_x000D_
  opacity: 0.65 !important;_x000D_
  display: inline-block;_x000D_
}_x000D_
_x000D_
.no-hover::before {_x000D_
  content: '';_x000D_
  background-color: transparent;_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  z-index: 60;_x000D_
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet" />_x000D_
_x000D_
<button class="btn btn-primary">hover</button>_x000D_
<span class="no-hover">_x000D_
  <button class="btn btn-primary ">no hover</button>_x000D_
</span>

You can implicitly convert between numerical types, even when that loses precision:

char c = i;

However, you might like to enable compiler warnings to avoid potentially lossy conversions like this. If you do, then use static_cast for the conversion.

Of the other casts:

• dynamic_cast only works for pointers or references to polymorphic class types;
• const_cast can't change types, only const or volatile qualifiers;
• reinterpret_cast is for special circumstances, converting between pointers or references and completely unrelated types. Specifically, it won't do numeric conversions.
• C-style and function-style casts do whatever combination of static_cast, const_cast and reinterpret_cast is needed to get the job done.

I know you already have several answers, but I was on a similar situation where my team didn't want to depend on a heavy libraries or anything related to bootstrap since we are using material so I made our own autocomplete control, using material-like styles, you can use my autocomplete or at least you can give a look to give you some guiadance, there was not much documentation on simple examples on how to upload your components to be shared on NPM.

This is the most coder-friendly version of specifying a unicode character:

degree_sign= u'\N{DEGREE SIGN}'

Note: must be a capital N in the \N construct to avoid confusion with the '\n' newline character. The character name inside the curly braces can be any case.

It's easier to remember the name of a character than its unicode index. It's also more readable, ergo debugging-friendly. The character substitution happens at compile time: the .py[co] file will contain a constant for u'°':

>>> import dis
>>> c= compile('u"\N{DEGREE SIGN}"', '', 'eval')
>>> dis.dis(c)
  1           0 LOAD_CONST               0 (u'\xb0')
              3 RETURN_VALUE
>>> c.co_consts
(u'\xb0',)
>>> c= compile('u"\N{DEGREE SIGN}-\N{EMPTY SET}"', '', 'eval')
>>> c.co_consts
(u'\xb0-\u2205',)
>>> print c.co_consts[0]

SQL doesn't typically allow you to reference column aliases in WHERE, GROUP BY or HAVING clauses. MySQL does support referencing column aliases in the GROUP BY and HAVING, but I stress that it will cause problems when porting such queries to other databases.

When in doubt, use the actual column name:

SELECT t.lat AS latitude 
  FROM poi_table t
 WHERE t.lat < 500

I added a table alias to make it easier to see what is an actual column vs alias.

Update

A computed column, like the one you see here:

SELECT *, 
       ( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) AS distance
  FROM poi_table 
 WHERE distance < 500;

...doesn't change that you can not reference a column alias in the WHERE clause. For that query to work, you'd have to use:

SELECT *, 
       ( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) AS distance
  FROM poi_table
 WHERE ( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) < 500;

Be aware that using a function on a column (IE: RADIANS(lat)) will render an index useless, if one exists on the column.

Generate pseudo random numbers between 1 and an [UPPER_LIMIT]

You can use the following to generate a number between 1 and an upper limit.

Math.abs(new Random().nextInt() % [UPPER_LIMIT]) + 1

Here is a specific example:

Example - Generate pseudo random numbers in the range 1 to 600:

Math.abs(new Random().nextInt() % 600) + 1

This will generate a random number within a range for you. In this case 1-600. You can change the value 600 to anything you need in the range of integers.

Generate pseudo random numbers between a [LOWER_LIMIT] and an [UPPER_LIMIT]

If you want to use a lower bound that is not equal to 1 then you can use the following formula.

Math.abs(new Random().nextInt() % ([UPPER_LIMIT] - [LOWER_LIMIT])) + [LOWER_LIMIT]

Here is a specific example:

Example - Generate pseudo random numbers in the range of 40 to 99:

Math.abs( new Random().nextInt() % (99 - 40) ) + 40

This will generate a random number within a range of 40 and 99.

In C# 8.0 and later you can use [^5..] to get the last five characters combined with a ? operator to avoid a potential ArgumentOutOfRangeException.

string input1 = "0123456789";
string input2 = "0123";
Console.WriteLine(input1.Length >= 5 ? input1[^5..] : input1); //returns 56789
Console.WriteLine(input2.Length >= 5 ? input2[^5..] : input2); //returns 0123

index-from-end-operator and range-operator

You can simply use this function with save() JPAfunction, but the object sent as parameter must contain an existing id in the database otherwise it will not work, because save() when we send an object without id, it adds directly a row in database, but if we send an object with an existing id, it changes the columns already found in the database.

public void updateUser(Userinfos u) {
    User userFromDb = userRepository.findById(u.getid());
    // crush the variables of the object found
    userFromDb.setFirstname("john"); 
    userFromDb.setLastname("dew");
    userFromDb.setAge(16);
    userRepository.save(userFromDb);
}

<input type="checkbox" @( Model.Checked == true ? "checked" : "" ) />

Try this:

String output = response.getEntity(String.class);

EDIT

Thanks to @Martin Spamer to mention that it will work for Jersey 1.x jars only. For Jersey 2.x use

String output = response.readEntity(String.class);

In case you want to run only tests from a specific class:

if __name__ == "__main__":
    unittest.main(MyCase())

It works for me in Python 3.6.

If you have pip install and you want to see what packages have been installed with your installer tools you can simply call this:

pip freeze

It will also include version numbers for the installed packages.

Update

pip has been updated to also produce the same output as pip freeze by calling:

pip list

Note

The output from pip list is formatted differently, so if you have some shell script that parses the output (maybe to grab the version number) of freeze and want to change your script to call list, you'll need to change your parsing code.

You can simply set a system property on the server as follows...

-Dspring.profiles.active=test

Edit: To add this to tomcat in eclipse, select Run -> Run Configurations and choose your Tomcat run configuration. Click the Arguments tab and add -Dspring.profiles.active=test at the end of VM arguments. Another way would be to add the property to your catalina.properties in your Servers project, but if you add it there omit the -D

Edit: For use with Spring Boot, you have an additional choice. You can pass the property as a program argument if you prepend the property with two dashes.

Here are two examples using a Spring Boot executable jar file...

System Property

[user@host ~]$ java -jar -Dspring.profiles.active=test myproject.jar

Program Argument

[user@host ~]$ java -jar myproject.jar --spring.profiles.active=test

Python calls expressions "expression statements", so the question is perhaps not fully formed.

A statement consists of pretty much anything you can do in Python: calculating a value, assigning a value, deleting a variable, printing a value, returning from a function, raising an exception, etc. The full list is here: http://docs.python.org/reference/simple_stmts.html#

An expression statement is limited to calling functions (e.g., math.cos(theta)"), operators ( e.g., "2+3"), etc. to produce a value.

There are many ways, one is to use a counter:

$i = 0;
foreach ($arr as $k => $v) {
    /* Do stuff */
    if (++$i == 2) break;
}

Other way would be to slice the first 2 elements, this isn't as efficient though:

foreach (array_slice($arr, 0, 2) as $k => $v) {
    /* Do stuff */
}

You could also do something like this (basically the same as the first foreach, but with for):

for ($i = 0, reset($arr); list($k,$v) = each($arr) && $i < 2; $i++) {
}

Spring Data is a convenience library on top of JPA that abstracts away many things and brings Spring magic (like it or not) to the persistence store access. It is primarily used for working with relational databases. In short, it allows you to declare interfaces that have methods like findByNameOrderByAge(String name); that will be parsed in runtime and converted into appropriate JPA queries.

Its placement atop of JPA makes its use tempting for:

1. Rookie developers who don't know SQL or know it badly. This is a recipe for disaster but they can get away with it if the project is trivial.

2. Experienced engineers who know what they do and want to spindle up things fast. This might be a viable strategy (but read further).

From my experience with Spring Data, its magic is too much (this is applicable to Spring in general). I started to use it heavily in one project and eventually hit several corner cases where I couldn't get the library out of my way and ended up with ugly workarounds. Later I read other users' complaints and realized that these issues are typical for Spring Data. For example, check this issue that led to hours of investigation/swearing:

 public TourAccommodationRate createTourAccommodationRate(
        @RequestBody TourAccommodationRate tourAccommodationRate
    ) {
        if (tourAccommodationRate.getId() != null) {
            throw new BadRequestException("id MUST NOT be specified in a body during entry creation");
        }

        // This is an ugly hack required for the Room slim model to work. The problem stems from the fact that
        // when we send a child entity having the many-to-many (M:N) relation to the containing entity, its
        // information is not fetched. As a result, we get NPEs when trying to access all but its Id in the
        // code creating the corresponding slim model. By detaching the entity from the persistence context we
        // force the ORM to re-fetch it from the database instead of taking it from the cache

        tourAccommodationRateRepository.save(tourAccommodationRate);
        entityManager.detach(tourAccommodationRate);
        return tourAccommodationRateRepository.findOne(tourAccommodationRate.getId());
    }

I ended up going lower level and started using JDBI - a nice library with just enough "magic" to save you from the boilerplate. With it, you have complete control over SQL queries and almost never have to fight the library.

To open at a specific line straight from the command line, use:

less +320123 filename

If you want to see the line numbers too:

less +320123 -N filename

You can also choose to display a specific line of the file at a specific line of the terminal, for when you need a few lines of context. For example, this will open the file with line 320123 on the 10th line of the terminal:

less +320123 -j 10 filename

@echo off

@echo Mysql Backup Created

pause;

I would say there is also a starred notation for the import ES6 keyword worth to mention.

If you try to console log Mix:

import * as Mix from "./A";
console.log(Mix);

You will get:

When should I use curly braces for ES6 import?

The brackets are golden when you need only specific components from the module, which makes smaller footprints for bundlers like webpack.

add_Pbl <= to_stdlogicvector(to_bitvector(dato_cu(25 downto 2)) sll 1);
add_Pbl is a std_logic_vector of 24 bit
dato_cu is a std_logic_vector of 32 bit

First, you need to convert the std_logic_vector with to_bitvector() function because sll statement works with logic 1 and 0 bits.

You can retrieve the email address from the logged in user's profile. Here is the code snippet

<?php

    $facebook = new Facebook(array(
      'appId'  => $initMe["appId"],
      'secret' => $initMe["appSecret"],
    ));

    $facebook->setAccessToken($initMe["accessToken"]);
    $user = $facebook->getUser();

    if ($user) {
        $user_profile = $facebook->api('/me');
        print_r($user_profile["email"]);
    }
?>

Just reference the variable inside the function; no magic, just use it's name. If it's been created globally, then you'll be updating the global variable.

You can override this behaviour by declaring it locally using var, but if you don't use var, then a variable name used in a function will be global if that variable has been declared globally.

That's why it's considered best practice to always declare your variables explicitly with var. Because if you forget it, you can start messing with globals by accident. It's an easy mistake to make. But in your case, this turn around and becomes an easy answer to your question.

Use .is(':checked') to determine whether or not it's checked, and then set your value accordingly.

More information here.

For creating a branch from another one can use this syntax as well:

git push origin refs/heads/<sourceBranch>:refs/heads/<targetBranch>

It is a little shorter than "git checkout -b " + "git push origin "

Bit of a c++11 take:

std::map<uint32_t, uint32_t> items;
std::vector<uint32_t> itemKeys;
for (auto & kvp : items)
{
    itemKeys.emplace_back(kvp.first);
    std::cout << kvp.first << std::endl;
}

Ever heard about appserver from techdivision?

It is written in php and works as a appserver managing multithreads for high traffic php applications. Is still in beta but very promesing.

There are multiple ways to do this:

1. Using SSIS (SQL Server Integration Services). It only imports data in your table. Column properties, constraints, keys, indices, stored procedures, triggers, security settings, users, logons, etc. are not transferred. However it is very simple process and can be done simply by going through wizard in SQL Server Management Studio.
2. Using combination of SSIS and DB creation scripts. This will get you data and all missing metadata that is not transferred by SSIS. This is also very simple. First transfer data using SSIS (see instructions below), then create DB Create script from SQL Azure database, and re-play it on your local database.
3. Finally, you can use Import/Export service in SQL Azure. This transfers data (with a schema objects) to Azure Blob Storage as a BACPAC. You will need an Azure Storage account and do this in Azure web portal. It is as simple as pressing an "Export" button in the Azure web portal when you select the database you want to export. The downside is that it is only manual procedure, I don't know a way to automate this through tools or scripts -- at least the first part that requires a click on the web page.

Manual procedure for method #1 (using SSIS) is the following:

• In Sql Server Management Studio (SSMS) create new empty database on your local SQL instance.
• Choose Import Data from context menu (right click the database -> Tasks -> Import data...)
• Type in connection parameters for the source (SQL Azure). Select ".Net Framework Data Provider for SqlServer" as a provider.
• Choose existing empty local database as destination.
• Follow the wizard -- you will be able to select tables data you want to copy. You can choose to skip any of the tables you don't need. E.g. if you keep application logs in database, you probably don't need it in your backup.

You can automate it by creating SSIS package and re-executing it any time you like to re-import the data. Note that you can only import using SSIS to a clean DB, you cannot do incremental updates to your local database once you already done it once.

Method #2 (SSID data plus schema objects) is very simple. First go though a steps described above, then create DB Creation script (righ click on database in SSMS, choose Generate Scripts -> Database Create). Then re-play this script on your local database.

Method #3 is described in the Blog here: http://dacguy.wordpress.com/2012/01/24/sql-azure-importexport-service-has-hit-production/. There is a video clip with the process of transferring DB contents to Azure Blob storage as BACPAC. After that you can copy the file locally and import it to your SQL instance. Process of importing BACPAC to Data-Tier application is described here: http://msdn.microsoft.com/en-us/library/hh710052.aspx.

Put the command

yum install php-gd

and restart the server (httpd, nginx, etc)

service httpd restart

TypeScript have a way of validating the type of a variable in runtime. You can add a validating function that returns a type predicate. So you can call this function inside an if statement, and be sure that all the code inside that block is safe to use as the type you think it is.

Example from the TypeScript docs:

function isFish(pet: Fish | Bird): pet is Fish {
   return (<Fish>pet).swim !== undefined;
}

// Both calls to 'swim' and 'fly' are now okay.
if (isFish(pet)) {
  pet.swim();
}
else {
  pet.fly();
}

See more at: https://www.typescriptlang.org/docs/handbook/advanced-types.html

Your markup should contain an additional attribute called ng-disabled whose value should be a condition or expression that would evaluate to be either true or false.

    <input data-ng-model="userInf.username"  class="span12 editEmail" 
       type="text"  placeholder="[email protected]"  
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="{condition or expression}"
/>

And in the controller you may have some code that would affect the value of ng-disabled directive.

you have to do like this...

if not "A%1" == "A"

if the input argument %1 is null, your code will have problem.

Having struggled with this issue for pretty much a full day hard coding in the ORG/REPO section into our build script getting the dreaded 'remote not found' error, eventually found a working solution to be to use the TRAVIS_REPO_SLUG. Switching this in for the hardcoded attributes worked immediately.

git remote set-url origin https://[ORG]:${TOKEN}@github.com/${TRAVIS_REPO_SLUG}

For your iframe give an outer div with style display:inline-block, And for your paragraph div also give display:inline-block

HTML

<div class="side">
    <iframe></iframe>
</div>

</div>

CSS

.side {
   display:inline-block;
}

In a Windows Forms project:

For the full path (filename included): string exePath = Application.ExecutablePath;
For the path only: string appPath = Application.StartupPath;

First things first ,

they are not always equal

    select 'Hello' from dual where 'Hello  ' like 'Hello';

    select 'Hello' from dual where 'Hello  ' =  'Hello';

when things are not always equal , talking about their performance isn't that relevant.

If you are working on strings and only char variables , then you can talk about performance . But don't use like and "=" as being generally interchangeable .

As you would have seen in many posts ( above and other questions) , in cases when they are equal the performance of like is slower owing to pattern matching (collation)

With the recent release of bootstrap 3, and the glyphicons being merged back to the main Bootstrap repo, Bootstrap CDN is now serving the complete Bootstrap 3.0 css including Glyphicons. The Bootstrap css reference is all you need to include: Glyphicons and its dependencies are on relative paths on the CDN site and are referenced in bootstrap.min.css.

In html:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet">

In css:

 @import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css");

Here is a working demo.

Note that you have to use .glyphicon classes instead of .icon:

Example:

<span class="glyphicon glyphicon-heart"></span>

Also note that you would still need to include bootstrap.min.js for usage of Bootstrap JavaScript components, see Bootstrap CDN for url.

If you want to use the Glyphicons separately, you can do that by directly referencing the Glyphicons css on Bootstrap CDN.

In html:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css" rel="stylesheet">

In css:

@import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css");

Since the css file already includes all the needed Glyphicons dependencies (which are in a relative path on the Bootstrap CDN site), adding the css file is all there is to do to start using Glyphicons.

Here is a working demo of the Glyphicons without Bootstrap.

You can use parameter from reCaptcha. By default it uses normal value on data-size, You just have to use compact to fit this on small devices or some-kind small width layouts.

example:

<div class="g-recaptcha" data-size="compact"></div>

I disagree with the accepted answer being "the easiest", particularly if you want to use virtualenv.

You can use the Unofficial Windows Binaries instead. Download the appropriate wheel from there, and install it with pip:

pip install pywin32-219-cp27-none-win32.whl

(Make sure you pick the one for the right version and bitness of Python).

You might be able to get the URL and install it via pip without downloading it first, but they're made it a bit harder to just grab the URL. Probably better to download it and host it somewhere yourself.

Yes, they are very different in theory, and in implementation.

Lexers are used to recognize "words" that make up language elements, because the structure of such words is generally simple. Regular expressions are extremely good at handling this simpler structure, and there are very high-performance regular-expression matching engines used to implement lexers.

Parsers are used to recognize "structure" of a language phrases. Such structure is generally far beyond what "regular expressions" can recognize, so one needs "context sensitive" parsers to extract such structure. Context-sensitive parsers are hard to build, so the engineering compromise is to use "context-free" grammars and add hacks to the parsers ("symbol tables", etc.) to handle the context-sensitive part.

Neither lexing nor parsing technology is likely to go away soon.

They may be unified by deciding to use "parsing" technology to recognize "words", as is currently explored by so-called scannerless GLR parsers. That has a runtime cost, as you are applying more general machinery to what is often a problem that doesn't need it, and usually you pay for that in overhead. Where you have lots of free cycles, that overhead may not matter. If you process a lot of text, then the overhead does matter and classical regular expression parsers will continue to be used.

You cannot do it for File, which is primarily an intelligent file path. Can you refactor your code so that it declares the variables, and passes around arguments, with type OutputStream instead of FileOutputStream? If so, see classes java.io.ByteArrayOutputStream and java.io.ByteArrayInputStream

OutputStream outStream = new ByteArrayOutputStream();
outStream.write(whatever);
outStream.close();
byte[] data = outStream.toByteArray();
InputStream inStream = new ByteArrayInputStream(data);
...

I could do this (demo):

<!doctype html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
</head>
<body>
    <form >
        <input type="file" id="f" data-max-size="32154" />
        <input type="submit" />
    </form>
<script>
$(function(){
    $('form').submit(function(){
        var isOk = true;
        $('input[type=file][data-max-size]').each(function(){
            if(typeof this.files[0] !== 'undefined'){
                var maxSize = parseInt($(this).attr('max-size'),10),
                size = this.files[0].size;
                isOk = maxSize > size;
                return isOk;
            }
        });
        return isOk;
    });
});
</script>
</body>
</html>

I am not sure about be the best way, but works fine and all code stays in your ArrayAdapter.

I would suggest to use this extension method to chunk the source list to the sub-lists by specified chunk size:

/// <summary>
/// Helper methods for the lists.
/// </summary>
public static class ListExtensions
{
    public static List<List<T>> ChunkBy<T>(this List<T> source, int chunkSize) 
    {
        return source
            .Select((x, i) => new { Index = i, Value = x })
            .GroupBy(x => x.Index / chunkSize)
            .Select(x => x.Select(v => v.Value).ToList())
            .ToList();
    }
}

For example, if you chunk the list of 18 items by 5 items per chunk, it gives you the list of 4 sub-lists with the following items inside: 5-5-5-3.

you can use framelayout to achieve this.

git remote manpage is pretty straightforward:

• https://www.kernel.org/pub/software/scm/git/docs/git-remote.html

Use

Older (backwards-compatible) syntax:
$ git remote rm upstream
Newer syntax for newer git versions: (* see below)
$ git remote remove upstream

Then do:    
$ git remote add upstream https://github.com/Foo/repos.git

or just update the URL directly:

$ git remote set-url upstream https://github.com/Foo/repos.git

or if you are comfortable with it, just update the .git/config directly - you can probably figure out what you need to change (left as exercise for the reader).

...
[remote "upstream"]
    fetch = +refs/heads/*:refs/remotes/upstream/*
    url = https://github.com/foo/repos.git
...

===

* Regarding 'git remote rm' vs 'git remote remove' - this changed around git 1.7.10.3 / 1.7.12 2 - see

https://code.google.com/p/git-core/source/detail?spec=svne17dba8fe15028425acd6a4ebebf1b8e9377d3c6&r=e17dba8fe15028425acd6a4ebebf1b8e9377d3c6

Log message

remote: prefer subcommand name 'remove' to 'rm'

All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.

'rm' is still supported and used in the test suite. It's just not
widely advertised.

You need to use css-loader when creating bundle with webpack.

Install it:

npm install css-loader --save-dev

And add it to loaders in your webpack configs:

module.exports = {
  module: {
    loaders: [
      { test: /\.css$/, loader: "style-loader!css-loader" },
      // ...
    ]
  }
};

After this, you will be able to include css files in js.

Else is executed if while loop did not break.

I kinda like to think of it with a 'runner' metaphor.

The "else" is like crossing the finish line, irrelevant of whether you started at the beginning or end of the track. "else" is only not executed if you break somewhere in between.

runner_at = 0 # or 10 makes no difference, if unlucky_sector is not 0-10
unlucky_sector = 6
while runner_at < 10:
    print("Runner at: ", runner_at)
    if runner_at == unlucky_sector:
        print("Runner fell and broke his foot. Will not reach finish.")
        break
    runner_at += 1
else:
    print("Runner has finished the race!") # Not executed if runner broke his foot.

Main use cases is using this breaking out of nested loops or if you want to run some statements only if loop didn't break somewhere (think of breaking being an unusual situation).

For example, the following is a mechanism on how to break out of an inner loop without using variables or try/catch:

for i in [1,2,3]:
    for j in ['a', 'unlucky', 'c']:
        print(i, j)
        if j == 'unlucky':
            break
    else: 
        continue  # Only executed if inner loop didn't break.
    break         # This is only reached if inner loop 'breaked' out since continue didn't run. 

print("Finished")
# 1 a
# 1 b
# Finished

Solved in my case, i look at

sudo tail -f /var/log/nginx/error.log

and error is php5-fpm.sock not found

I look at sudo ls -lah /var/run/

there was no php5-fpm.sock

I edit the www.conf  

sudo vim /etc/php5/fpm/pool.d/www.conf

change

listen = 127.0.0.1:9000

for

listen = /var/run/php5-fpm.sock

and reboot

Another option is CSVLogger: https://keras.io/callbacks/#csvlogger. It creates a csv file appending the result of each epoch. Even if you interrupt training, you get to see how it evolved.

I also saw similar problems reported in ReSharper which did not lead to compile/runtime errors.

These were mostly seen when using "{x:Type ...}" or "{x:Static ...}" markup, causing ReSharper to report "Cannot resolve symbol 'Type'" or "Cannot resolve symbol 'Static'" errors.

Additionally there were many errors like "Invalid markup extension type: expected type is '<type>', actual type is '...Extension'".

The problem resolved itself when I added a reference to the System.Xaml assembly.

As of year 2020, JetBrains suggests to commit the .idea folder.
The JetBrains IDEs (webstorm, intellij, android studio, pycharm, clion, etc.) automatically add that folder to your git repository (if there's one).
Inside the folder .idea, has been already created a .gitignore, updated by the IDE itself to avoid to commit user related settings that may contains privacy/password data.

It is safe (and usually useful) to commit the .idea folder.

[1] First Design your tableview cell in StoryBoard.

[2] Put below table view delegate method

//MARK: - Tableview Delegate Methods

    totalHeight +=   UpdateRowHeight(<cell name>.<label name>, textToAdd: <your array>[indexPath.row])    

    return totalHeight
}


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{


    var cell : <cell name>! = tableView.dequeueReusableCellWithIdentifier(“<cell identifire>”, forIndexPath: indexPath) as! CCell_VideoCall

    if(cell == nil)
    {
        cell = NSBundle.mainBundle().loadNibNamed("<cell identifire>", owner: self, options: nil)[0] as! <cell name>;
    }


    <cell name>.<label name>.text = <your array>[indexPath.row] as? String



    return cell as <cell name>
}

//MARK: - Custom Methods

func UpdateRowHeight ( ViewToAdd : UILabel , textToAdd : AnyObject  ) -> CGFloat{

        where !strName!.isEmpty
    {

I think @Dmitri has nice solution at Matching strings with wildcard https://stackoverflow.com/a/30300521/1726296

Based on his solution, I have created two extension methods. (credit goes to him)

May be helpful.

public static String WildCardToRegular(this String value)
{
        return "^" + Regex.Escape(value).Replace("\\?", ".").Replace("\\*", ".*") + "$";
}

public static bool WildCardMatch(this String value,string pattern,bool ignoreCase = true)
{
        if (ignoreCase)
            return Regex.IsMatch(value, WildCardToRegular(pattern), RegexOptions.IgnoreCase);

        return Regex.IsMatch(value, WildCardToRegular(pattern));
}

Usage:

string pattern = "file.*";

var isMatched = "file.doc".WildCardMatch(pattern)

or

string xlsxFile = "file.xlsx"
var isMatched = xlsxFile.WildCardMatch(pattern)

In foreach loop instead of carBootSaleList use carBootSaleList.data.

You probably do not need answer anymore, but it could help someone.

Since you're using VB.NET, you'll need the following code:

Dim newString As String = origString.Replace(vbCr, "").Replace(vbLf, "")

You could use escape characters (\r and \n) in C#, but these won't work in VB.NET. You have to use the equivalent constants (vbCr and vbLf) instead.

I use the following way to handle the many-to-many relationship where only foreign keys are involved.

So for inserting:

public void InsertStudentClass (long studentId, long classId)
{
    using (var context = new DatabaseContext())
    {
        Student student = new Student { StudentID = studentId };
        context.Students.Add(student);
        context.Students.Attach(student);

        Class class = new Class { ClassID = classId };
        context.Classes.Add(class);
        context.Classes.Attach(class);

        student.Classes = new List<Class>();
        student.Classes.Add(class);

        context.SaveChanges();
    }
}

For deleting,

public void DeleteStudentClass(long studentId, long classId)
{
    Student student = context.Students.Include(x => x.Classes).Single(x => x.StudentID == studentId);

    using (var context = new DatabaseContext())
    {
        context.Students.Attach(student);
        Class classToDelete = student.Classes.Find(x => x.ClassID == classId);
        if (classToDelete != null)
        {
            student.Classes.Remove(classToDelete);
            context.SaveChanges();
        }
    }
}

jQuery should be able to find even hidden elements. It also has the :visible and :hidden selectors to find both visible and hidden elements.

Does this help? Not sure without more info.

/(.*)<FooBar>/s

the s causes Dot (.) to match carriage returns

You are missing <context:annotation-config /> from your spring context so the annotations are not being scanned!

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 results container div has position: relative meaning it is still in the document flow and will change the layout of elements around it. You need to use position: absolute to achieve a 'floating' effect.

You should also check the markup you're using, you have phantom <li>s with no container <ul>, you could probably replace both the div#suggestions and div#autoSuggestionsList with a single <ul> and get the desired result.

Not so much an answer but more of an FYI:I've just hit this and found this question as a result of searching. Here is the details of my experience:

Shell error

This perhaps indicates the other answer (JaKi) was experiencing the same thing, where some connections were purged and access made possible again for the shell (other clients)

class Foo {
    const BAR = 'baz';
}

echo Foo::BAR;

This is the only way to make class constants. These constants are always globally accessible via Foo::BAR, but they're not accessible via just BAR.

To achieve a syntax like Foo::baz()->BAR, you would need to return an object from the function baz() of class Foo that has a property BAR. That's not a constant though. Any constant you define is always globally accessible from anywhere and can't be restricted to function call results.

You can center a fixed or absolute positioned element setting right and left to 0, and then margin-left & margin-right to auto as if you were centering a static positioned element.

#example {
    position: fixed;
    /* center the element */
    right: 0;
    left: 0;
    margin-right: auto;
    margin-left: auto;
    /* give it dimensions */
    min-height: 10em;
    width: 90%;
}

See this example working on this fiddle.

In your case the "Vendor code 17002" is the equivalent of the ORA-12541 error: It's most likely that your listener is down, or has an improper port or service name. From the docs:

ORA-12541: TNS no listener

Cause: Listener for the source repository has not been started.

Action: Start the Listener on the machine where the source repository resides.

It may be late to answer this question but I hope to document 2 good features from Pandas: pandas.Series.str.split() with regular expression and pandas.Series.explode().

import pandas as pd
import numpy as np

df = pd.DataFrame(
    {'CustNum': [32363, 31316],
     'CustomerName': ['McCartney, Paul', 'Lennon, John'],
     'ItemQty': [3, 25],
     'Item': ['F04', 'F01'],
     'Seatblocks': ['2:218:10:4,6', '1:13:36:1,12 1:13:37:1,13'],
     'ItemExt': [60, 360]
    }
)

print(df)
print('-'*80+'\n')

df['Seatblocks'] = df['Seatblocks'].str.split('[ :]')
df = df.explode('Seatblocks').reset_index(drop=True)
cols = list(df.columns)
cols.append(cols.pop(cols.index('CustomerName')))
df = df[cols]


print(df)
print('='*80+'\n')
print(df[df['CustomerName'] == 'Lennon, John'])

The output is:

Comparison of strings is very easy in Ruby:

v1 = "string1"
v2 = "string2"
puts v1 == v2 # prints false
puts "hello"=="there" # prints false
v1 = "string2"
puts v1 == v2 # prints true

Make sure your var2 is not an array (which seems to be like)

I use CTRL-SHIFT-DELETE which activates the privacy feature, allowing you to clear your cache, reset cookies, etc, all at once. You can even configure it so that it just DOES it, instead of popping up a dialog box asking you to confirm.

I think what BrandonS wants is not the position of the mouse relative to the root element, but rather the position of some descendant element.

For that, there is the TransformToAncestor method:

Point relativePoint = myVisual.TransformToAncestor(rootVisual)
                              .Transform(new Point(0, 0));

Where myVisual is the element that was just double-clicked, and rootVisual is Application.Current.MainWindow or whatever you want the position relative to.

}

In the above example they going to display all user and particular id details now I want to use both id and name,

1) localhost:8093/plejson/shop/user <---this link will display all user details
2) localhost:8093/plejson/shop/user/11 <----if i use 11 in link means, it will display particular user 11 details

now I want to use both id and name

localhost:8093/plejson/shop/user/11/raju <-----------------like this it means we can use any one in this please help me out.....

With modern JavaScript it can be done like this:

const divs = document.querySelectorAll('.a');

divs.forEach(el => el.addEventListener('click', event => {
  console.log(event.target.getAttribute("data-el"));
}));

1. Gets all elements by class name
2. Loops over all elements with using forEach
3. Attach an event listener on each element
4. Uses event.target to retrieve more information for specific element

Try this if the 0.0.0.0 method doesn't work

Boring Stuff

I personally battled a lot to get my app accessible to other devices(laptops and mobile phones) through a local-server. I tried the 0.0.0.0 method, but no luck. Then I tried changing the port, but it just didn't work. So, after trying a bunch of different combinations, I arrived to this one, and it solved my problem of deploying my app on a local server.

Steps

1. Get the local IPv4 address of your computer. This can be done by typing ipconfig on Windows and ifconfig on Linux and Mac.

Please note: The above step is to be performed on the machine you are serving the app on, and on not the machine on which you are accessing it. Also note, that the IPv4 address might change if you disconnect and reconnect to the network.

2. Now, simply run the flask app with the acquired IPv4 address.

   flask run -h 192.168.X.X

   E.g. In my case (see the image), I ran it as:

   flask run -h 192.168.1.100

On my mobile device

Optional Stuff

If you are performing this procedure on Windows and using Power Shell as the CLI, and you still aren't able to access the website, try a CTRL + C command in the shell that's running the app. Power Shell gets frozen up sometimes and it needs a pinch to revive. Doing this might even terminate the server, but it sometimes does the trick.

That's it. Give a thumbs up if you found this helpful.

Some more optional stuff

I have created a short Powershell script that will get you your IP address whenever you need one:

$env:getIp = ipconfig
if ($env:getIp -match '(IPv4[\sa-zA-Z.]+:\s[0-9.]+)') {
    if ($matches[1] -match '([^a-z\s][\d]+[.\d]+)'){
        $ipv4 = $matches[1]
    }
}
echo $ipv4

Save it to a file with .ps1 extension (for PowerShell), and run it on before starting your app. You can save it in your project folder and run it as:

.\getIP.ps1; flask run -h $ipv4

Note: I saved the above shellcode in getIP.ps1.

Cool.

This little example shows how the $rootScope emit a event that will be listen by a children scope in another controller.

(function(){


angular
  .module('ExampleApp',[]);

angular
  .module('ExampleApp')
  .controller('ExampleController1', Controller1);

Controller1.$inject = ['$rootScope'];

function Controller1($rootScope) {
  var vm = this, 
      message = 'Hi my children scope boy';

  vm.sayHi = sayHi;

  function sayHi(){
    $rootScope.$broadcast('greeting', message);
  }

}

angular
  .module('ExampleApp')
  .controller('ExampleController2', Controller2);

Controller2.$inject = ['$scope'];

function Controller2($scope) {
  var vm = this;

  $scope.$on('greeting', listenGreeting)

  function listenGreeting($event, message){
    alert(['Message received',message].join(' : '));
  }

}


})();

The answer of @gayathri bottom explain technically the differences of all those methods in the scope angular concept and their implementations $scope and $rootScope.

Imagine that you have something like this:

[{id:1, cat:'sedan'},{id:2, cat:'sport'},{id:3, cat:'sport'},{id:4, cat:'sedan'}]

By doing this: const categories = [...new Set(cars.map((car) => car.cat))]

You will get this: ['sedan','sport']

Explanation: 1. First, we are creating a new Set by passing an array. Because Set only allows unique values, all duplicates will be removed.

2. Now the duplicates are gone, we’re going to convert it back to an array by using the spread operator ...

Set Doc:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set Spread OperatorDoc: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax

Simple way to say is: If you implement interface that means you are implementing all methods of it and if you extending the class you are inheriting method of your choice... In this case,there is only a one method named Run() so better to implement Runnable interface..

In my case, I want to skip the Pods folder when cloning the project. I did step by step like below and it works for me. Hope it helps.

mkdir my_folder
cd my_folder
git init
git remote add origin -f <URL>
git config core.sparseCheckout true 
echo '!Pods/*\n/*' > .git/info/sparse-checkout
git pull origin master

Memo, If you want to skip more folders, just add more line in sparse-checkout file.

There are two ways of closing an alert dialog.

Option 1:

AlertDialog#create().dismiss();

Option 2:

The DialogInterface#dismiss();

Out of the box, the framework calls DialogInterface#dismiss(); when you define event listeners for the buttons:

1. AlertDialog#setNegativeButton();
2. AlertDialog#setPositiveButton();
3. AlertDialog#setNeutralButton();

for the Alert dialog.

For some reason Alt + Shift + F didn't work for me on Mac Visual Studio Code 1.3.1, and actually the command "Format Document" don't worked at all. But command Formatter worked very well.

So you can use Command + Shift + P and type Formatter or make your own shortcut in menu File → Preferences → Keyboard Shortcuts → Command + K Command + S then type Formatter and add your shortcut.

See an example:

NodeJS (and newer browsers) have a nice shortcut to get the current time in milliseconds.

var timeInMss = Date.now()

Which has a performance boost compared with

var timeInMss = new Date().getTime()

Because you do not need to create a new object.

As has just happened to me - this can also happen when you add a required property to your model without updating your form. In this case the ValidationSummary will not list the error message.

Here's how I fixed it:

1. Opened the Install Cerificates.Command.The shell script got executed.
2. Opened the Python 3.6.5 and typed in nltk.download().The download graphic window opened and all the packages got installed.

If you are using one of the built-in controller instances, then one of the parameters to your controller method will be the Request object. You can call request.getParameter("value1") to get the POST (or PUT) data value.

If you are using Spring MVC annotations, you can add an annotated parameter to your method's parameters:

@RequestMapping(value = "/someUrl")
public String someMethod(@RequestParam("value1") String valueOne) {
 //do stuff with valueOne variable here
}
