This answer comes a little late, but it completes the response.

In order to avoid a field from an entity to be persisted in DB one can use one of the two mechanisms:

@Transient - the JPA annotation marking a field as not persistable

transient keyword in java. Beware - using this keyword, will prevent the field to be used with any serialization mechanism from java. So, if the field must be serialized you'd better use just the @Transient annotation.

At least some versions of SQL (Oracle, Informix, DB2, ISO Standard) support:

WHERE MOD(value, 2) = 1

MySQL supports '%' as the modulus operator:

WHERE value % 2 = 1

This is a very old thread, but here's a very thorough answer and sample code.

\r is the string representation of Carriage Return from the ASCII character set. It's the same as octal 015 [chr(0o15)] or hexidecimal 0d [chr(0x0d)] or decimal 13 [chr(13)]. See man ascii for a boring read. It (\r) is a pretty portable representation and is easy enough for people to read. It very simply means to move the carriage on the typewriter all the way back to the start without advancing the paper. It's the CR part of CRLF which means Carriage Return and Line Feed.

print() is a function in Python 3. In Python 2 (any version that you'd be interested in using), print can be forced into a function by importing its definition from the __future__ module. The benefit of the print function is that you can specify what to print at the end, overriding the default behavior of \n to print a newline at the end of every print() call.

sys.stdout.flush tells Python to flush the output of standard output, which is where you send output with print() unless you specify otherwise. You can also get the same behavior by running with python -u or setting environment variable PYTHONUNBUFFERED=1, thereby skipping the import sys and sys.stdout.flush() calls. The amount you gain by doing that is almost exactly zero and isn't very easy to debug if you conveniently forget that you have to do that step before your application behaves properly.

And a sample. Note that this runs perfectly in Python 2 or 3.

from __future__ import print_function

import sys
import time

ANS = 42
FACTORS = {n for n in range(1, ANS + 1) if ANS % n == 0}

for i in range(1, ANS + 1):
    if i in FACTORS:
        print('\r{0:d}'.format(i), end='')
        sys.stdout.flush()
        time.sleep(ANS / 100.0)
else:
    print()

It's probably faster and easier to use numpy.digitize():

import numpy
data = numpy.random.random(100)
bins = numpy.linspace(0, 1, 10)
digitized = numpy.digitize(data, bins)
bin_means = [data[digitized == i].mean() for i in range(1, len(bins))]

An alternative to this is to use numpy.histogram():

bin_means = (numpy.histogram(data, bins, weights=data)[0] /
             numpy.histogram(data, bins)[0])

Try for yourself which one is faster... :)

Not really a nice query but :

SELECT * from (
    SELECT max(Salary) from Employee
    ) as a
LEFT OUTER JOIN 
    (SELECT MAX(Salary) FROM Employee
        WHERE Salary NOT IN (SELECT MAX(Salary) FROM Employee )) as b
ON 1=1

You can also use OPENROWSET to import excel file in sql server.

SELECT * INTO Your_Table FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
                        'Excel 12.0;Database=C:\temp\MySpreadsheet.xlsx',
                        'SELECT * FROM [Data$]')

In your example, Java is performing integer arithmetic, rounding off the result of the division.

Based on your question, you would like to perform floating-point arithmetic. To do so, at least one of your terms must be specified as (or converted to) floating-point:

Specifying floating point:

3.0/2
3.0/2.0
3/2.0

Converting to floating point:

int a = 2;
int b = 3;
float q = ((float)a)/b;

or

double q = ((double)a)/b;

(See Java Traps: double and Java Floating-Point Number Intricacies for discussions on float and double)

**//With the help of this code u not just sort the arrays in alphabetical order but also can take string from user or console or keyboard

import java.util.Scanner;
import java.util.Arrays;
public class ReadName
{
final static int ARRAY_ELEMENTS = 3;
public static void main(String[] args)
{
String[] theNames = new String[5];
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the names: ");
for (int i=0;i<theNames.length ;i++ )
{           
theNames[i] = keyboard.nextLine();
}
System.out.println("**********************");
Arrays.sort(theNames);
for (int i=0;i<theNames.length ;i++ )
{
System.out.println("Name are " + theNames[i]);
}
}
}**

SELECT * FROM big_table ORDER BY A DESC LIMIT 10

What about:

list =[ ['a','b'], ['a','c'], ['b','d'] ]
search = 'b'

filter(lambda x:x[1]==search,list)

This will return each list in the list of lists with the second element being equal to search.

you can use paste0 or cat method to combine string with variable values in R

For Example:

paste0("Value of A : ", a)

cat("Value of A : ", a)

Do this:

from threading import Thread

def func1():
    print('Working')

def func2():
    print("Working")

if __name__ == '__main__':
    Thread(target = func1).start()
    Thread(target = func2).start()

$total=0;
foreach($group as $key=>$value)
{
   echo $key. " = " .$value. "<br>"; 
   $total+= $value;
}
echo $total;

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

If you are using a zsh terminal you're able to use wildcard magic:

sed -i "" "s/search/high-replace/g" *.txt

Use the .split() method. When specifying an empty string as the separator, the split() method will return an array with one element per character.

entry = prompt("Enter your name")
entryArray = entry.split("");

Also make sure your code doesn't have true for setBlockNetworkLoads

webView.getSettings().setBlockNetworkLoads (false);

The difference is simple: they cause different warning messages to be emitted when compiling:

1156942.c:7:31: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘int *’ [-Wformat=]
     printf("memory address = %d\n", &a); // prints "memory add=-12"
                               ^
1156942.c:8:31: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 2 has type ‘int *’ [-Wformat=]
     printf("memory address = %u\n", &a); // prints "memory add=65456"
                               ^

If you pass your pointer as a void* and use %p as the conversion specifier, then you get no error message:

#include <stdio.h>

int main()
{
    int a = 5;
    // check the memory address
    printf("memory address = %d\n", &a); /* wrong */
    printf("memory address = %u\n", &a); /* wrong */
    printf("memory address = %p\n", (void*)&a); /* right */
}

It's more convenient to use a session, this way you don't have to remember to set headers each time:

session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})

session.get('https://httpbin.org/headers')

By default, session also manages cookies for you. In case you want to disable that, see this question.

<div style="width:300px; text-align:right;">
        <img src="someimgage.gif">
</div>

HTML alone does not support this. You need to use some JS.

And also consider nowadays people use popup blocker in browsers.

<a href="javascript:window.open('document.aspx','mypopuptitle','width=600,height=400')">open popup</a>

In visual Studio 2017 goto Debug->Option then check Debugging->general-> and check this option

        } else {
            json = JSON.stringify(json);
        }
    }
    return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g,

In jQuery 3 and perhaps earlier versions, the following simpler config also works for individual requests:

            xhrFields: {

            },
            success: successFunc
        }
    );

The full error I was getting in Firefox Dev Tools -> Network tab (in the Security tab for an individual request) was:

An error occurred during a connection to foo.bar.com.SSL peer was unable to negotiate an acceptable set of security parameters.Error code: SSL_ERROR_HANDSHAKE_FAILURE_ALERT

The UNION ALL operator may be what you are looking for.

With this operator, you can concatenate the resultsets from multiple queries together, preserving all of the rows from each. Note that a UNION operator (without the ALL keyword) will eliminate any "duplicate" rows which exist in the resultset. The UNION ALL operator preserves all of the rows from each query (and will likely perform better since it doesn't have the overhead of performing the duplicate check and removal operation).

The number of columns and data type of each column must match in each of the queries. If one of the queries has more columns than the other, we sometimes include dummy expressions in the other query to make the columns and datatypes "match". Often, it's helpful to include an expression (an extra column) in the SELECT list of each query that returns a literal, to reveal which of the queries was the "source" of the row.

SELECT 'q1' AS source, a, b, c, d FROM t1 WHERE ...
UNION ALL
SELECT 'q2', t2.fee, t2.fi, t2.fo, 'fum' FROM t2 JOIN t3 ON ...
UNION ALL
SELECT 'q3', '1', '2', buckle, my_shoe FROM t4

You can wrap a query like this in a set of parenthesis, and use it as an inline view (or "derived table", in MySQL lingo), so that you can perform aggregate operations on all of the rows.

SELECT t.a
     , SUM(t.b)
     , AVG(t.c)
  FROM (
         SELECT 'q1' AS source, a, b, c, d FROM t1
          UNION ALL
         SELECT 'q2', t2.fee, t2.fi, t2.fo, 'fum' FROM t2
       ) t
 GROUP BY t.a
 ORDER BY t.a

you can use nested loop in follow :

ArrayList<Class1> l1 = new ArrayList<Class1>();
ArrayList<Class1> l2 = new ArrayList<Class1>();

        Iterator iterator1 = l1.iterator();
        boolean repeated = false;

        while (iterator1.hasNext())
        {
            Class1 c1 = (Class1) iterator1.next();
            for (Class1 _c: l2) {
                if(_c.getId() == c1.getId())
                    repeated = true;
            }
            if(!repeated)
                l2.add(c1);
        }

If you want the external public IP and you're in a cloud environment like AWS or Azure, you can use the ipify_facts module:

# TODO: SECURITY: This requires that we trust ipify to provide the correct public IP. We could run our own ipify server.
- name: Get my public IP from ipify.org
  ipify_facts:

This will place the public IP into the variable ipify_public_ip.

I got this error for multi-threading scenario (specifically when dealing with ZMQ). It turned out that socket was still being connected on one thread while another thread already started sending data. The events that occured due to another thread tried to access variables that weren't created yet. If your scenario involves multi-threading and if things work if you add bit of delay then you might have similar issue.

To call a function inside a same controller in any laravel version follow as bellow

When you decorate a model property with [DataType(DataType.Date)] the default template in ASP.NET MVC 4 generates an input field of type="date":

<input class="text-box single-line" 
       data-val="true" 
       data-val-date="The field EstPurchaseDate must be a date."
       id="EstPurchaseDate" 
       name="EstPurchaseDate" 
       type="date" value="9/28/2012" />

Browsers that support HTML5 such Google Chrome render this input field with a date picker.

In order to correctly display the date, the value must be formatted as 2012-09-28. Quote from the specification:

value: A valid full-date as defined in [RFC 3339], with the additional qualification that the year component is four or more digits representing a number greater than 0.

You could enforce this format using the DisplayFormat attribute:

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public Nullable<System.DateTime> EstPurchaseDate { get; set; }

I had the same problem even though I had:

• a freshly downloaded JDK 1.8.0

• JAVA_HOME is set

• java -version on command line reports 1.8

• Java in control panel is set to 1.8

• downloaded Eclipse Mars

Eclipse only let me choose a compiler compliance level op to 1.7 in the compiler preferences, even though my installed JRE is 1.8.0. I also couldn't see a 1.8 in the Execution Environments underneath Installed JREs, only a JavaSE-1.7 (which I haven't even got installed!). When I clicked on that, it shows "jdk1.8.0" as a compatible JRE, so I selected that, but still no change.

Then I unzipped Eclipse Mars into a brand new directory, created a new project, and now I can select 1.8, hurrah! That greatly reduced the "Duplicate methods named spliterator..." errors I was getting when compiling my code under Java 1.8, however, there is still one left:

Duplicate default methods named spliterator with the parameters () and () are inherited from the types List and Set.

However, that's likely because I'm extending AbstractList and implementing Set, so I've fixed that for now by removing the implements Set because it doesn't really add anything in my case (other than signifying that my collection has only unique elements)

Putting each of your top-level windows into it's own separate class gives you code re-use and better code organization. Any buttons and relevant methods that are present in the window should be defined inside this class. Here's an example (taken from here):

import tkinter as tk

class Demo1:
    def __init__(self, master):
        self.master = master
        self.frame = tk.Frame(self.master)
        self.button1 = tk.Button(self.frame, text = 'New Window', width = 25, command = self.new_window)
        self.button1.pack()
        self.frame.pack()
    def new_window(self):
        self.newWindow = tk.Toplevel(self.master)
        self.app = Demo2(self.newWindow)

class Demo2:
    def __init__(self, master):
        self.master = master
        self.frame = tk.Frame(self.master)
        self.quitButton = tk.Button(self.frame, text = 'Quit', width = 25, command = self.close_windows)
        self.quitButton.pack()
        self.frame.pack()
    def close_windows(self):
        self.master.destroy()

def main(): 
    root = tk.Tk()
    app = Demo1(root)
    root.mainloop()

if __name__ == '__main__':
    main()

Compiling some of the ideas to get the wifi ip from the WifiManager in a nicer kotlin solution:

private fun getWifiIp(context: Context): String? {
  return context.getSystemService<WifiManager>().let {
     when {
      it == null -> "No wifi available"
      !it.isWifiEnabled -> "Wifi is disabled"
      it.connectionInfo == null -> "Wifi not connected"
      else -> {
        val ip = it.connectionInfo.ipAddress
        ((ip and 0xFF).toString() + "." + (ip shr 8 and 0xFF) + "." + (ip shr 16 and 0xFF) + "." + (ip shr 24 and 0xFF))
      }
    }
  }
}

Alternatively you can get the ip adresses of ip4 loopback devices via the NetworkInterface:

fun getNetworkIp4LoopbackIps(): Map<String, String> = try {
  NetworkInterface.getNetworkInterfaces()
    .asSequence()
    .associate { it.displayName to it.ip4LoopbackIps() }
    .filterValues { it.isNotEmpty() }
} catch (ex: Exception) {
  emptyMap()
}

private fun NetworkInterface.ip4LoopbackIps() =
  inetAddresses.asSequence()
    .filter { !it.isLoopbackAddress && it is Inet4Address }
    .map { it.hostAddress }
    .filter { it.isNotEmpty() }
    .joinToString()

I realize this is an old question, but the Bootstrap framework has a built in class (sr-only) to handle hiding text on everything but screen readers:

The most likely reason why the Java Runtime Environment JRE or Java Development Kit JDK is that it's owned by Oracle not Google and they would need a redistribution agreement which if you know there is some history between the two companies.

Lucky for us that Sun Microsystems before it was bought by Oracle open sourced Java and MySQL a win for us little guys.... Thank you Sun!

Google should probably have a caveat saying you may also need JRE OR JDK

By turning them into integers instead:

percent = (int(pyc) / int(tpy)) * 100;

In python 3, the input() function returns a string. Always. This is a change from Python 2; the raw_input() function was renamed to input().

Several things:

Age is not an integer - it is a nullable integer type. They are not the same. See the documentation for Nullable<T> on MSDN for details.

?? is the null coalesce operator, not the ternary operator (actually called the conditional operator).

To check if a nullable type has a value use HasValue, or check directly against null:

if(Age.HasValue)
{
   // Yay, it does!
}

if(Age == null)
{
   // It is null :(
}

Here's a working example that should point you in the right direction:

class Foo {
    _name;

    get Name() {
        return this._name;
    }

    set Name(val) {
        this._name = val;
    }
}

Getters and setters in JavaScript are just normal functions. The setter is a function that takes a parameter whose value is the value being set.

Here's my simple vanilla JavaScript code:

let a = 'one,two,"three, but with a comma",four,"five, with ""quotes"" in it.."'
console.log(splitQuotes(a))

function splitQuotes(line) {
  if(line.indexOf('"') < 0) 
    return line.split(',')

  let result = [], cell = '', quote = false;
  for(let i = 0; i < line.length; i++) {
    char = line[i]
    if(char == '"' && line[i+1] == '"') {
      cell += char
      i++
    } else if(char == '"') {
      quote = !quote;
    } else if(!quote && char == ',') {
      result.push(cell)
      cell = ''
    } else {
      cell += char
    }
    if ( i == line.length-1 && cell) {
      result.push(cell)
    }
  }
  return result
}

All the above did not work for me (XCode 7.3) so I read Apple reference on how to do, and it is much simpler than described above. According to Apple:

Localized values are not stored in the Info.plist file itself. Instead, you store the values for a particular localization in a strings file with the name InfoPlist.strings. You place this file in the same language-specific project directory that you use to store other resources for the same localization.

Accordingly, I created a string file named InfoPlist.strings and placed it in the xx.lproj folder of the "xx" language (and added it to the project using File->Add Files to ...). That's it. No need for the key "Localized resources can be mixed" = YES, and no need for InfoPlist.strings in base.lproj or en.lproj.

The application uses the Info.plist key-value as the default value if it can not find a key in the language specific file. Thus, I put my English value in the Info.plist file and the translated one in the language specific file, tested and everything works.

In particular, there is no need to localize the InfoPlist.strings (which creates a version of the file in the base.lproj, en.lroj, and xx.lproj), and in my case going that way did not work.

Set to cookie in the main domain -

document.cookie = "key=value;domain=.mydomain.com"

and then take the data from any main domain or sub domain and set it on the localStorage

Very simple way in codeigniter to call a method of one controller to other controller

1. Controller A 
   class A extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
    }
    function custom_a()
    {
    }
}

2. Controller B 

   class B extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
    }
    function custom_b()
    {
            require_once(APPPATH.'controllers/a.php'); //include controller
            $aObj = new a();  //create object 
            $aObj->custom_a(); //call function
    }
}

Given a staging table with 70 columns and only 4 representing duplicates, this code will return the offending columns:

SELECT 
    COUNT(*)
    ,LTRIM(RTRIM(S.TransactionDate)) 
    ,LTRIM(RTRIM(S.TransactionTime))
    ,LTRIM(RTRIM(S.TransactionTicketNumber)) 
    ,LTRIM(RTRIM(GrossCost)) 
FROM Staging.dbo.Stage S
GROUP BY 
    LTRIM(RTRIM(S.TransactionDate)) 
    ,LTRIM(RTRIM(S.TransactionTime))
    ,LTRIM(RTRIM(S.TransactionTicketNumber)) 
    ,LTRIM(RTRIM(GrossCost)) 
HAVING COUNT(*) > 1

.

Add this to your package.json , “dependency”

"bootstrap": "^3.3.7",

In .angular-cli.json file, to your “Styles” add

"../node_modules/bootstrap/dist/css/bootstrap.css"

update your npm by using this command

npm update

This function is using yield:

function a($items) {
    foreach ($items as $item) {
        yield $item + 1;
    }
}

It is almost the same as this one without:

function b($items) {
    $result = [];
    foreach ($items as $item) {
        $result[] = $item + 1;
    }
    return $result;
}

The only one difference is that a() returns a generator and b() just a simple array. You can iterate on both.

Also, the first one does not allocate a full array and is therefore less memory-demanding.

Wrap each row of values to be inserted in brackets/parenthesis (value1, value2, value3) and separate the brackets/parenthesis by comma for as many as you wish to insert into the table.

INSERT INTO example
VALUES
  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

Unless you are really concerned with performance, and by that I mean, "Why are you using .Net instead of C++?" you should stick with List<>. It's easier to maintain and does all the dirty work of resizing an array behind the scenes for you. (If necessary, List<> is pretty smart about choosing array sizes so it doesn't need to usually.)

Got to your laravel folder :: App/http/Middleware/VerifyCsrfToken.php

<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

class VerifyCsrfToken extends BaseVerifier
{
    /**
     * The URIs that should be excluded from CSRF verification.
     *
     * @var array
     */
    protected $except = [
        // Pass your URI here. example ::

        '/employer/registration'
    ];
}

And it will exclude this url from the Csrf validation. Works for me.

Using JSONSerialization always felt unSwifty and unwieldy, but it is even more so with the arrival of Codable in Swift 4. If you wield a [String:Any] in front of a simple struct it will ... hurt. Check out this in a Playground:

import Cocoa

let data = "[{\"form_id\":3465,\"canonical_name\":\"df_SAWERQ\",\"form_name\":\"Activity 4 with Images\",\"form_desc\":null}]".data(using: .utf8)!

struct Form: Codable {
    let id: Int
    let name: String
    let description: String?

    private enum CodingKeys: String, CodingKey {
        case id = "form_id"
        case name = "form_name"
        case description = "form_desc"
    }
}

do {
    let f = try JSONDecoder().decode([Form].self, from: data)
    print(f)
    print(f[0])
} catch {
    print(error)
}

With minimal effort handling this will feel a whole lot more comfortable. And you are given a lot more information if your JSON does not parse properly.

Either in your admin.py or in a separate forms.py you can add a ModelForm class and then declare your extra fields inside that as you normally would. I've also given an example of how you might use these values in form.save():

from django import forms
from yourapp.models import YourModel


class YourModelForm(forms.ModelForm):

    extra_field = forms.CharField()

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)
        # ...do something with extra_field here...
        return super(YourModelForm, self).save(commit=commit)

    class Meta:
        model = YourModel

To have the extra fields appearing in the admin just:

1. edit your admin.py and set the form property to refer to the form you created above
2. include your new fields in your fields or fieldsets declaration

Like this:

class YourModelAdmin(admin.ModelAdmin):

    form = YourModelForm

    fieldsets = (
        (None, {
            'fields': ('name', 'description', 'extra_field',),
        }),
    )

UPDATE: In django 1.8 you need to add fields = '__all__' to the metaclass of YourModelForm.

Just want to share what worked on my end, in case it would be able to help someone else too. Alternatively based on Paty Lustosa's answer above, please allow me to add another approach derived from this site where he used an ajax approach for the source method

http://salman-w.blogspot.ca/2013/12/jquery-ui-autocomplete-examples.html#example-3

The kicker is the resulting "string" or json format from your php script (listing.php below) that derives the result set to be shown in the autocomplete field should follow something like this:

    {"list":[
     {"value": 1, "label": "abc"},
     {"value": 2, "label": "def"},
     {"value": 3, "label": "ghi"}
    ]}

Then on the source portion of the autocomplete method:

    source: function(request, response) {
        $.getJSON("listing.php", {
            term: request.term
        }, function(data) {                     
            var array = data.error ? [] : $.map(data.list, function(m) {
                return {
                    label: m.label,
                    value: m.value
                };
            });
            response(array);
        });
    },
    select: function (event, ui) {
        $("#autocomplete_field").val(ui.item.label); // display the selected text
        $("#field_id").val(ui.item.value); // save selected id to hidden input
        return false;
    }

Hope this helps... all the best!

For Windows, here's a quick 1 liner example of how to install a file..on multiple devices

FOR /F "skip=1"  %x IN ('adb devices') DO start adb -s %x install -r myandroidapp.apk

If you plan on including this in a batch file, replace %x with %%x, as below

FOR /F "skip=1"  %%x IN ('adb devices') DO start adb -s %%x install -r myandroidapp.apk

You could use the Laravel query builder, but this is not the best way to do it.

Check Wader's answer below for the Eloquent way - which is better as it allows you to check that there is actually a user that matches the email address, and handle the error if there isn't.

DB::table('users')
        ->where('email', $userEmail)  // find your user by their email
        ->limit(1)  // optional - to ensure only one record is updated.
        ->update(array('member_type' => $plan));  // update the record in the DB. 

If you have multiple fields to update you can simply add more values to that array at the end.

I was using Markwon for markdown parsing in Android. The following worked great:

"My first line  \nMy second line  \nMy third line  \nMy last line"

...two spaces followed by \n at the end of each line.

Sometimes we developer stuck in small designing part of any UI screen. One of the most irritating requirement is under line text. Don’t worry here is the solution.

Underlining a text in a UILabel using Objective C

UILabel *label=[[UILabel alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
label.backgroundColor=[UIColor lightGrayColor];
NSMutableAttributedString *attributedString;
attributedString = [[NSMutableAttributedString alloc] initWithString:@"Apply Underlining"];
[attributedString addAttribute:NSUnderlineStyleAttributeName value:@1 range:NSMakeRange(0,
[attributedString length])];
[label setAttributedText:attributedString];

Underlining a text in UILabel using Swift

 label.backgroundColor = .lightGray
 let attributedString = NSMutableAttributedString.init(string: "Apply UnderLining")
 attributedString.addAttribute(NSUnderlineStyleAttributeName, value: 1, range:
NSRange.init(location: 0, length: attributedString.length))
 label.attributedText = attributedString

Work with this code :

{!! include ('css/app.css') !!}

You can create the headers on the fly (no need to specify delimiter when the delimiter is a comma):

Import-CSV $filepath -Header IP1,IP2,IP3,IP4 | Foreach-Object{
   Write-Host $_.IP1
   Write-Host $_.IP2
   ...
}

Though this question has been answered. I would like to put something extra, i.e. if there is a file exist with the directory name that you are trying to create than it should prompt an error. For future visitors.

public static void makeDir()
{
    File directory = new File(" dirname ");
    if (directory.exists() && directory.isFile())
    {
        System.out.println("The dir with name could not be" +
        " created as it is a normal file");
    }
    else
    {
        try
        {
            if (!directory.exists())
            {
                directory.mkdir();
            }
            String username = System.getProperty("user.name");
            String filename = " path/" + username + ".txt"; //extension if you need one

        }
        catch (IOException e)
        {
            System.out.println("prompt for error");
        }
    }
}

You can use the following to programmatically center TextView text in Kotlin:

textview.gravity = Gravity.CENTER

myObservableCollection.ToList().Sort((x, y) => x.Property.CompareTo(y.Property));

You need to retrieve and disect the information into what you need.

while($row = mysql_fetch_array($result)) {
 echo "img src='",$row['filename'],"' width='175' height='200' />";
}

Running commands as Super Admin worked for me. Retry after closing Editor your are working in.

Before going to answer read this Documentation once. Then you clearly understand the answer.

Try this It may work for you.

Object.keys(data.shareInfo[i]).length

Just as a note you can also use this for iPads:

activityViewController.popoverPresentationController?.sourceView = sender

So the popover pops from the sender (the button in that case).

I prefer to solve this in the classic way, creating a new array of my desired data type:

List<MyNewType> newArray = new ArrayList<>();
myOldArray.forEach(info -> newArray.add(objectMapper.convertValue(info, MyNewType.class)));

You can set the color of a JLabel by altering the foreground category:

JLabel title = new JLabel("I love stackoverflow!", JLabel.CENTER);

title.setForeground(Color.white);

As far as I know, the simplest way to create the two-color label you want is to simply make two labels, and make sure they get placed next to each other in the proper order.

With CSS positioning, you can place an element exactly where you want it on your page.

When you are going to use CSS positioning, the first thing you need to do is use the CSS property position to tell the browser if you're going to use absolute or relative positioning.

Both Positions are having different features. In CSS Once you set Position then you can able to use top, right, bottom, left attributes.

Absolute Position

An absolute position element is positioned relative to the first parent element that has a position other than static.

Relative Position

A relative positioned element is positioned relative to its normal position.

To position an element relatively, the property position is set as relative. The difference between absolute and relative positioning is how the position is being calculated.

You can use Socket.io tester, this app lets you connect to a socket.io server and subscribe to a certain topic and/or lets you send socket messages to the server

In the .NET world there are two types of CLRs, "full" CLRs and Core CLRs, and these are quite different things.

There are two "full" CLR implementations, the Microsoft native .NET CLR (for Windows) and the Mono CLR (which itself has implementations for Windows, linux and unix (Mac OS X and FreeBSD)). A full CLR is exactly that - everything, pretty much, that you need. As such, "full" CLRs tend to be large in size.

Core CLRs are on the other hand are cut down, and much smaller. Because they are only a core implementation, they are unlikely to have everything you need in them, so with Core CLRs you add feature sets to the CLR that your specific software product uses, using NuGet. There are Core CLR implementations for Windows, linux (various) and unix (Mac OS X and FreeBSD) in the mix. Microsoft have or are refactoring the .NET framework libraries for Core CLR too, to make them more portable for the core context. Given mono's presence on *nix OSs it would be a surprise if the Core CLRs for *nix did not include some mono code base, but only the Mono community and Microsoft could tell us that for sure.

Also, I'd concur with Nico in that Core CLRs are new -- it's at RC2 at the moment I think. I wouldn't depend on it for production code yet.

To answer your question you could delivery your site on linux using Core CLR or Mono, and these are two different ways of doing it. If you want a safe bet right now I'd go with mono on linux, then port if you want to later, to Core.

You should open text files using rU so newlines are properly transformed, see http://docs.python.org/library/functions.html#open. This way there's no need to check for \r\n.

List comprehension works well, and looping through with enumerate can save you some memory (b/c the operation's essentially being done in place).

There's also functional programming. See usage of map:

>>> a = [1,2,3,2,3,4,3,5,6,6,5,4,5,4,3,4,3,2,1]
>>> map(lambda x: x if x != 4 else 'sss', a)
[1, 2, 3, 2, 3, 'sss', 3, 5, 6, 6, 5, 'sss', 5, 'sss', 3, 'sss', 3, 2, 1]

I know this is old, but for those surfing this question, the answer by MUG4N will align all columns that use the same defaultcellstyle. I'm not using autogeneratecolumns so that is not acceptable. Instead I used:

e.Column.DefaultCellStyle = new DataGridViewCellStyle(e.Column.DefaultCellStyle);
e.Column.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;

In this case e is from:

Grd_ColumnAdded(object sender, DataGridViewColumnEventArgs e)  

Try this:

{ "dt" : { "$gte" : ISODate("2013-10-01") } }

From the answer here, spark.sql.shuffle.partitions configures the number of partitions that are used when shuffling data for joins or aggregations.

spark.default.parallelism is the default number of partitions in RDDs returned by transformations like join, reduceByKey, and parallelize when not set explicitly by the user. Note that spark.default.parallelism seems to only be working for raw RDD and is ignored when working with dataframes.

If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions) (don't forget to assign it to a new val) in your code.

To change the settings in your code you can simply do:

sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")

Alternatively, you can make the change when submitting the job to a cluster with spark-submit:

./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300

Assign your image to a string. Eg image Now set icon to a fixed size label.

image.setIcon(new javax.swing.ImageIcon(image.getScaledInstance(50,50,WIDTH)));

My solution:

public static <T > void copyAllFields(T to, T from) {
        Class<T> clazz = (Class<T>) from.getClass();
        // OR:
        // Class<T> clazz = (Class<T>) to.getClass();
        List<Field> fields = getAllModelFields(clazz);

        if (fields != null) {
            for (Field field : fields) {
                try {
                    field.setAccessible(true);
                    field.set(to,field.get(from));
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                }
            }
        }
    }

public static List<Field> getAllModelFields(Class aClass) {
    List<Field> fields = new ArrayList<>();
    do {
        Collections.addAll(fields, aClass.getDeclaredFields());
        aClass = aClass.getSuperclass();
    } while (aClass != null);
    return fields;
}

From the Mongo documentation:

The mongoexport utility takes a collection and exports to either JSON or CSV. You can specify a filter for the query, or a list of fields to output

Fiddle Links: Source code - Preview - Small version
Update: This small function will only execute code in a single direction. If you want full support (eg event listeners / getters), have a look at Listening for Youtube Event in jQuery

As a result of a deep code analysis, I've created a function: function callPlayer requests a function call on any framed YouTube video. See the YouTube Api reference to get a full list of possible function calls. Read the comments at the source code for an explanation.

On 17 may 2012, the code size was doubled in order to take care of the player's ready state. If you need a compact function which does not deal with the player's ready state, see http://jsfiddle.net/8R5y6/.

            "id": frame_id
        }), "*");
    }
    /* IE8 does not support addEventListener... */
    function messageEvent(add, listener) {
        var w3 = add ? window.addEventListener : window.removeEventListener;
        w3 ?
            w3('message', listener, !1)
        :
            (add ? window.attachEvent : window.detachEvent)('onmessage', listener);
    }
}

Usage:

callPlayer("whateverID", function() {
    // This function runs once the player is ready ("onYouTubePlayerReady")
    callPlayer("whateverID", "playVideo");
});
// When the player is not ready yet, the function will be queued.
// When the iframe cannot be found, a message is logged in the console.
callPlayer("whateverID", "playVideo");

Possible questions (& answers):

Q: It doesn't work!
A: "Doesn't work" is not a clear description. Do you get any error messages? Please show the relevant code.

Q: playVideo does not play the video.
A: Playback requires user interaction, and the presence of allow="autoplay" on the iframe. See https://developers.google.com/web/updates/2017/09/autoplay-policy-changes and https://developer.mozilla.org/en-US/docs/Web/Media/Autoplay_guide

Q: I have embedded a YouTube video using <iframe src="http://www.youtube.com/embed/As2rZGPGKDY" />but the function doesn't execute any function!
A: You have to add ?enablejsapi=1 at the end of your URL: /embed/vid_id?enablejsapi=1.

Q: I get error message "An invalid or illegal string was specified". Why?
A: The API doesn't function properly at a local host (file://). Host your (test) page online, or use JSFiddle. Examples: See the links at the top of this answer.

Q: How did you know this?
A: I have spent some time to manually interpret the API's source. I concluded that I had to use the postMessage method. To know which arguments to pass, I created a Chrome extension which intercepts messages. The source code for the extension can be downloaded here.

Q: What browsers are supported?
A: Every browser which supports JSON and postMessage.

• IE 8+
• Firefox 3.6+ (actually 3.5, but document.readyState was implemented in 3.6)
• Opera 10.50+
• Safari 4+
• Chrome 3+

Revision history

• 17 may 2012
  Implemented onYouTubePlayerReady: callPlayer('frame_id', function() { ... }).
  Functions are automatically queued when the player is not ready yet.
• 24 july 2012
  Updated and successully tested in the supported browsers (look ahead).
• 10 october 2013 When a function is passed as an argument, callPlayer forces a check of readiness. This is needed, because when callPlayer is called right after the insertion of the iframe while the document is ready, it can't know for sure that the iframe is fully ready. In Internet Explorer and Firefox, this scenario resulted in a too early invocation of postMessage, which was ignored.
• 12 Dec 2013, recommended to add &origin=* in the URL.
• 2 Mar 2014, retracted recommendation to remove &origin=* to the URL.
• 9 april 2019, fix bug that resulted in infinite recursion when YouTube loads before the page was ready. Add note about autoplay.

You can use css and the :hover pseudo-property. Here is a simple demo. It uses the following css:

a span.tooltip {display:none;}
a:hover span.tooltip {position:absolute;top:30px;left:20px;display:inline;border:2px solid green;}

Note that older browsers have limited support for :hover.

Usually, I replace a recursive algorithm by an iterative algorithm by pushing the parameters that would normally be passed to the recursive function onto a stack. In fact, you are replacing the program stack by one of your own.

var stack = [];
stack.push(firstObject);

// while not empty
while (stack.length) {

    // Pop off end of stack.
    obj = stack.pop();

    // Do stuff.
    // Push other objects on the stack as needed.
    ...

}

Note: if you have more than one recursive call inside and you want to preserve the order of the calls, you have to add them in the reverse order to the stack:

foo(first);
foo(second);

has to be replaced by

stack.push(second);
stack.push(first);

Edit: The article Stacks and Recursion Elimination (or Article Backup link) goes into more details on this subject.

Another way: instead CONCAT function we can use double pipe: :lastname || '%'

@Query("select c from Customer c where c.lastName LIKE :lastname||'%'")
List<Customer> findCustomByLastName( @Param("lastname") String lastName);

You can put anywhere, prefix, suffix or both

:lastname ||'%'  
'%' || :lastname  
'%' || :lastname || '%'  

You can also check with composer:

composer show laravel/framework

Also it's possible to avoid using JavaScript for drop-down effect, and use CSS3 transition, by adding this small piece of code to your style:

.dropdown .dropdown-menu {
    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    -ms-transition: all 0.3s;
    -o-transition: all 0.3s;
    transition: all 0.3s;

    max-height: 0;
    display: block;
    overflow: hidden;
    opacity: 0;
}

.dropdown.open .dropdown-menu { /* For Bootstrap 4, use .dropdown.show instead of .dropdown.open */
    max-height: 300px;
    opacity: 1;
}

The only problem with this way is that you should manually specify max-height. If you set a very big value, your animation will be very quick.

It works like a charm if you know the approximate height of your dropdowns, otherwise you still can use javascript to set a precise max-height value.

Here is small example: DEMO

! There is small bug with padding in this solution, check Jacob Stamm's comment with solution.

ary.GetLength(0) 
ary.GetLength(1)

for 2 dimensional array

• packed means it will use the smallest possible space for struct Ball - i.e. it will cram fields together without padding
• aligned means each struct Ball will begin on a 4 byte boundary - i.e. for any struct Ball, its address can be divided by 4

These are GCC extensions, not part of any C standard.

If you are using, Putty session, then it automatically copies selection. If we have used "set mouse=a" option in vim, selecting using Shift+Mouse drag selects the text automatically. Need to check in X-term.

Just for the sake of completeness, we can use the operators [ and [[:

set.seed(1)
df <- data.frame(v1 = runif(10), v2 = letters[1:10])

Several options

df[df[1] < 0.5 | df[2] == "g", ] 
df[df[[1]] < 0.5 | df[[2]] == "g", ] 
df[df["v1"] < 0.5 | df["v2"] == "g", ]

df$name is equivalent to df[["name", exact = FALSE]]

Using dplyr:

library(dplyr)
filter(df, v1 < 0.5 | v2 == "g")

Using sqldf:

library(sqldf)
sqldf('SELECT *
      FROM df 
      WHERE v1 < 0.5 OR v2 = "g"')

Output for the above options:

          v1 v2
1 0.26550866  a
2 0.37212390  b
3 0.20168193  e
4 0.94467527  g
5 0.06178627  j

Try "ssh-add" which worked for me.

Not sure it applies here also but in the case of protractor when using navigate().to(...) the history is being kept but when using get() it is lost.

One of my test was failing because I was using get() 2 times in a row and then doing a navigate().back(). Because the history was lost, when going back it went to the about page and an error was thrown:

Error: Error while waiting for Protractor to sync with the page: {}

I managed to find a relatively clean straightforward way to do this. To see it working click on my webpage: http://developersfound.com/yde-portfolio.html and hover over the 'Youtube Demos' link.

Below are two snippets to show how this can be done quite easily:

I achieved this with an iFrame. Assuming this DOM is 'yde-home.html' Which is the source of your iFrame.

<!DOCTYPE html>
<html>
<head>
    <title>iFrame Container</title>
    <script type="text/javascript" src="js/jquery-2.1.4.min.js"></script>
    <style type="text/css">.OBJ-1 { border:none; }</style>
    <script>
        $(document).ready(function() {
            $('#myHiddenButton').trigger('click');
        });
    </script>
</head>

<body>

    <section style="visibility: hidden;">
        <button id="myHiddenButton" onclick="$(location).attr('href', '"http://www.youtube.com/embed/wtwOZMXCe-c?version=3&amp;start=0&amp;rel=0&amp;fs=1&amp;wmode=transparent;");">View Full Screen</button>
    </section>

    <section class="main-area-inner" style="background:transparent;margin-left:auto;margin-right:auto;position:relative;width:1080px;height:720px;">
        <iframe src="http://www.youtube.com/embed/wtwOZMXCe-c?version=3&amp;start=0&amp;rel=0&amp;fs=1&amp;wmode=transparent;"
        class="OBJ-1" style="position:absolute;left:79px;top:145px;width:1080px;height:720px;">
        </iframe>
    </section>

</body>

</html>

Assume this is the DOM that loads the iFrame.

<!DOCTYPE html>
<html>
<head>
    <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'>
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
    <title>Full Screen Youtube</title>
    <script type="text/javascript" src="js/jquery-2.1.4.min.js"></script>
    <script>
        $(document).ready(function() {});           
    </script>
</head>

<body>

    <iframe name="iframe-container" id="iframe-container" src="yde-home.html" style="width: 100%; height: 100%;">
        <p>Your browser does not support iFrames</p>
    </iframe>

</body>

</html>

I've also checked this against the W3c Validator and it validates a HTML5 with no errors.

It is also important to note that: Youtube embed URLs sometimes check to see if the request is coming from a server so it may be necessary to set up your test environment to listen on your external IP. So you may need to set up port forwarding on your router for this solution to work. Once you've set up port forwarding just test from the external IP instead of LocalHost. Remember that some routers need port forwarding from LocalHost/loopback but most use the same IP that you used to log into the router. For example if your router login page is 192.168.0.1, then the port forward would have to use 192.168.0.? where ? could be any unused number (you may need to experiment). From this address you would add the ports that your test environment listen from (normally 80, 81, 8080 or 8088).

I did found a way to convert (even bad) html into well formed XML. I started to base this on the DOM loadHTML function. However during time several issues occurred and I optimized and added patches to correct side effects.

  function tryToXml($dom,$content) {
    if(!$content) return false;

    // xml well formed content can be loaded as xml node tree
    $fragment = $dom->createDocumentFragment();
    // wonderfull appendXML to add an XML string directly into the node tree!

    // aappendxml will fail on a xml declaration so manually skip this when occurred
    if( substr( $content,0, 5) == '<?xml' ) {
      $content = substr($content,strpos($content,'>')+1);
      if( strpos($content,'<') ) {
        $content = substr($content,strpos($content,'<'));
      }
    }

    // if appendXML is not working then use below htmlToXml() for nasty html correction
    if(!@$fragment->appendXML( $content )) {
      return $this->htmlToXml($dom,$content);
    }

    return $fragment;
  }



  // convert content into xml
  // dom is only needed to prepare the xml which will be returned
  function htmlToXml($dom, $content, $needEncoding=false, $bodyOnly=true) {

    // no xml when html is empty
    if(!$content) return false;

    // real content and possibly it needs encoding
    if( $needEncoding ) {
      // no need to convert character encoding as loadHTML will respect the content-type (only)
      $content =  '<meta http-equiv="Content-Type" content="text/html;charset='.$this->encoding.'">' . $content;
    }

    // return a dom from the content
    $domInject = new DOMDocument("1.0", "UTF-8");
    $domInject->preserveWhiteSpace = false;
    $domInject->formatOutput = true;

    // html type
    try {
      @$domInject->loadHTML( $content );
    } catch(Exception $e){
      // do nothing and continue as it's normal that warnings will occur on nasty HTML content
    }
        // to check encoding: echo $dom->encoding
        $this->reworkDom( $domInject );

    if( $bodyOnly ) {
      $fragment = $dom->createDocumentFragment();

      // retrieve nodes within /html/body
      foreach( $domInject->documentElement->childNodes as $elementLevel1 ) {
       if( $elementLevel1->nodeName == 'body' and $elementLevel1->nodeType == XML_ELEMENT_NODE ) {
         foreach( $elementLevel1->childNodes as $elementInject ) {
           $fragment->insertBefore( $dom->importNode($elementInject, true) );
         }
        }
      }
    } else {
      $fragment = $dom->importNode($domInject->documentElement, true);
    }

    return $fragment;
  }



    protected function reworkDom( $node, $level = 0 ) {

        // start with the first child node to iterate
        $nodeChild = $node->firstChild;

        while ( $nodeChild )  {
            $nodeNextChild = $nodeChild->nextSibling;

            switch ( $nodeChild->nodeType ) {
                case XML_ELEMENT_NODE:
                    // iterate through children element nodes
                    $this->reworkDom( $nodeChild, $level + 1);
                    break;
                case XML_TEXT_NODE:
                case XML_CDATA_SECTION_NODE:
                    // do nothing with text, cdata
                    break;
                case XML_COMMENT_NODE:
                    // ensure comments to remove - sign also follows the w3c guideline
                    $nodeChild->nodeValue = str_replace("-","_",$nodeChild->nodeValue);
                    break;
                case XML_DOCUMENT_TYPE_NODE:  // 10: needs to be removed
                case XML_PI_NODE: // 7: remove PI
                    $node->removeChild( $nodeChild );
                    $nodeChild = null; // make null to test later
                    break;
                case XML_DOCUMENT_NODE:
                    // should not appear as it's always the root, just to be complete
                    // however generate exception!
                case XML_HTML_DOCUMENT_NODE:
                    // should not appear as it's always the root, just to be complete
                    // however generate exception!
                default:
                    throw new exception("Engine: reworkDom type not declared [".$nodeChild->nodeType. "]");
            }
            $nodeChild = $nodeNextChild;
        } ;
    }

Now this also allows to add more html pieces into one XML which I needed to use myself. In general it can be used like this:

        $c='<p>test<font>two</p>';
    $dom=new DOMDocument('1.0', 'UTF-8');

$n=$dom->appendChild($dom->createElement('info')); // make a root element

if( $valueXml=tryToXml($dom,$c) ) {
  $n->appendChild($valueXml);
}
    echo '<pre/>'. htmlentities($dom->saveXml($n)). '</pre>';

In this example '<p>test<font>two</p>' will nicely be outputed in well formed XML as '<info><p>test<font>two</font></p></info>'. The info root tag is added as it will also allow to convert '<p>one</p><p>two</p>' which is not XML as it has not one root element. However if you html does for sure have one root element then the extra root <info> tag can be skipped.

With this I'm getting real nice XML out of unstructured and even corrupted HTML!

I hope it's a bit clear and might contribute to other people to use it.

I call it "positional expansion", as opposed to ** which I call "keyword expansion".

You can take advantage of Groovy features like with(), improvements to URLConnection, and simplified getters/setters:

GET:

String getResult = new URL('http://mytestsite/bloop').text

POST:

String postResult
((HttpURLConnection)new URL('http://mytestsite/bloop').openConnection()).with({
    requestMethod = 'POST'
    doOutput = true
    setRequestProperty('Content-Type', '...') // Set your content type.
    outputStream.withPrintWriter({printWriter ->
        printWriter.write('...') // Your post data. Could also use withWriter() if you don't want to write a String.
    })
    // Can check 'responseCode' here if you like.
    postResult = inputStream.text // Using 'inputStream.text' because 'content' will throw an exception when empty.
})

Note, the POST will start when you try to read a value from the HttpURLConnection, such as responseCode, inputStream.text, or getHeaderField('...').

For parseInt to work, your string should have only numerical data. Something like this:

 str1 = "123.00";
 str2 = "50.00";
 total = parseInt(str1)+parseInt(str2);
 alert(total);

Can you split the string before you start processing them for a total?

This is an old school approach, but if you're performing an iterative update or insert operation in SQL, something that runs for a long time, it's a good idea to periodically (programmatically) call "checkpoint". Calling "checkpoint" causes SQL to write to disk all of those memory-only changes (dirty pages, they're called) and items stored in the transaction log. This has the effect of cleaning out your transaction log periodically, thus preventing problems like the one described.

Adding an approach to this old question just for the fun of it:

$ cat input.file # file containing input that needs to be processed
a;b;c;d;e
1;2;3;4;5
no delimiter here
124;adsf;15454
foo;bar;is;null;info

$ cat tmp.sh # showing off the script to do the job
#!/bin/bash
delim=';'
while read -r line; do  
    while [[ "$line" =~ "$delim" ]]; do
        line=$(cut -d"$delim" -f 2- <<<"$line")
    done
    echo "$line"
done < input.file

$ ./tmp.sh # output of above script/processed input file
e
5
no delimiter here
15454
info

Besides bash, only cut is used. Well, and echo, I guess.

Okay, so this post is from six months ago, but I thought I would add some info here for people who are confused about the whole API key/MD5 fingerprint business. It took me a while to figure out, so I assume others have had trouble with it too (unless I'm just that dull).

These directions are for Windows XP, but I imagine it is similar for other versions of Windows. It appears Mac and Linux users have an easier time with this so I won't address them.

So in order to use mapviews in your Android apps, Google wants to check in with them so you can sign off on an Android Maps APIs Terms Of Service agreement. I think they don't want you to make any turn-by-turn GPS apps to compete with theirs or something. I didn't really read it. Oops.

So go to http://code.google.com/android/maps-api-signup.html and check it out. They want you to check the "I have read and agree with the terms and conditions" box and enter your certificate's MD5 fingerprint. Wtf is that, you might say. I don't know, but just do what I say and your Android app doesn't get hurt.

Go to Start>Run and type cmd to open up a command prompt. You need to navigate to the directory with the keytool.exe file, which might be in a slightly different place depending on which version JDK you have installed. Mine is in C:\Program Files\Java\jdk1.6.0_21\bin but try browsing to the Java folder and see what version you have and change the path accordingly.

After navigating to C:\Program Files\Java\<"your JDK version here">\bin in the command prompt, type

keytool -list -keystore "C:/Documents and Settings/<"your user name here">/.android/debug.keystore"

with the quotes. Of course <"your user name here"> would be your own Windows username.

(If you are having trouble finding this path and you are using Eclipse, you can check Window>preferences>Android>Build and check out the "Default Debug keystore")

Press enter and it will prompt you for a password. Just press enter. And voila, at the bottom is your MD5 fingerprint. Type your fingerprint into the text box at the Android Maps API Signup page and hit Generate API Key.

And there's your key in all its glory, with a handy sample xml layout with your key entered for you to copy and paste.

The Apache filter is built for iterating files in a known directory. To allow wildcards in the directory also, you would have to split the path on '\' or '/' and do a filter on each part separately.

This is because of lack of Capability .... If you see the Inner Exception you will see this message

"Access is denied.
Access to speech functionality requires ID_CAP_SPEECH_RECOGNITION to be defined in the manifest."

So to get rid of this exception. turn on the capability for Speech Recognition from the Manifest file.

I had the same problem, and It solved my Problem. :)

You can do all that by using just one RelativeLayout (which, btw, don't need android:orientation parameter). So, instead of having a LinearLayout, containing a bunch of stuff, you can do something like:

<RelativeLayout>
    <ImageButton
        android:layout_width="wrap_content"
        android:id="@+id/the_first_one"
        android:layout_alignParentLeft="true"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_toRightOf="@+id/the_first_one"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"/>
</RelativeLayout>

As you noticed, there are some XML parameters missing. I was just showing the basic parameters you had to put. You can complete the rest.

Why could you not just do something like this?

class Foo {
  constructor(myObj){
     Object.assign(this, myObj);
  }
  get name() { return this._name; }
  set name(v) { this._name = v; }
}

let foo = new Foo({ name: "bat" });
foo.toJSON() //=> your json ...

This is an answered question, but I'll give my "one cent":

Business rules belong in the model. The "model" always consists of (logically or physically separated):

• presentation model - a set of classes that is well suited for use in the view (it's tailored toward specific UI/presentation),
• domain model - the UI-independent portion of the model, and
• repository - the storage-aware portion of the "model".

Business rules live in the domain model, are exposed in a presentation-suitable form to the "presentation" model and are sometimes duplicated (or also enforced) in the "data layer".

That example is pretty vague, but maybe something like this?

items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [''.join(items[3:6])]

It basically does a splice (or assignment to a slice) operation. It removes items 3 to 6 and inserts a new list in their place (in this case a list with one item, which is the concatenation of the three items that were removed.)

For any type of list, you could do this (using the + operator on all items no matter what their type is):

items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [reduce(lambda x, y: x + y, items[3:6])]

This makes use of the reduce function with a lambda function that basically adds the items together using the + operator.

You can use dateutil.parser.parse (install with python -m pip install python-dateutil) to parse strings into datetime objects.

dateutil.parser.parse will attempt to guess the format of your string, if you know the exact format in advance then you can use datetime.strptime which you supply a format string to (see Brent Washburne's answer).

from dateutil.parser import parse

a = "2012-10-09T19:00:55Z"

b = parse(a)

print(b.weekday())
# 1 (equal to a Tuesday)

Use the hashchange event:

window.addEventListener("hashchange", function(e) {
  // ...
})

If you need to support older browsers, check out the hashChange Event section in Modernizr's HTML5 Cross Browser Polyfills wiki page.

>>> def duplicates(lst, item):
...   return [i for i, x in enumerate(lst) if x == item]
... 
>>> duplicates(List, "A")
[0, 2]

To get all duplicates, you can use the below method, but it is not very efficient. If efficiency is important you should consider Ignacio's solution instead.

>>> dict((x, duplicates(List, x)) for x in set(List) if List.count(x) > 1)
{'A': [0, 2]}

As for solving it using the index method of list instead, that method takes a second optional argument indicating where to start, so you could just repeatedly call it with the previous index plus 1.

>>> List.index("A")
0
>>> List.index("A", 1)
2

EDIT Fixed issue raised in comments.

First of all, there're two kinds of keystores.

Individual and General

The application will use the one indicated in the startup or the default of the system.

It will be a different folder if JRE or JDK is running, or if you check the personal or the "global" one.

They are encrypted too

In short, the path will be like:

You can find those maven properties in the super pom.

You find the jar here:

${M2_HOME}/lib/maven-model-builder-3.0.3.jar

Open the jar with 7-zip or some other archiver (or use the jar tool).

Navigate to

org/apache/maven/model

There you'll find the pom-4.0.0.xml.

It contains all those "short cuts":

<project>
    ...
    <build>
        <directory>${project.basedir}/target</directory>
        <outputDirectory>${project.build.directory}/classes</outputDirectory>

Update

After some lobbying I am adding a link to the pom-4.0.0.xml. This allows you to see the properties without opening up the local jar file.

Use the CAST to the new DATE data type in SQL Server 2008 to compare just the date portion:

IF CAST(DateField1 AS DATE) = CAST(DateField2 AS DATE)

We were getting an error related to this after a recent release of code to one of our development environments. We have an application that is a child of another application. This relationship has been working fine for YEARS until yesterday.

The problem:
We were getting a yellow stack trace error due to duplicate keys being entered. This is because both the web.config for the child and parent applications had this key. But this existed for many years like this without change. Why all of sudden its an issue now?

The solution:
The reason this was never a problem is because the keys AND values were always the same. Yesterday we updated our SQL connection strings to include the Application Name in the connection string. This made the string unique and all of sudden started to fail.

Without doing any research on the exact reason for this, I have to assume that when the child application inherits the parents web.config values, it ignores identical key/value pairs.

We were able to solve it by wrapping the connection string like this

    <location path="." inheritInChildApplications="false">
        <connectionStrings>
            <!-- Updated connection strings go here -->
        </connectionStrings>
    </location>

Edit: I forgot to mention that I added this in the PARENTS web.config. I didn't have to modify the child's web.config.

Thanks for everyones help on this, saved our butts.

There is a really simple way to do this in a CSS only way.

Apply an opacity to 0, therefore making it invisible, but it will still react to JavaScript events and CSS selectors. In the hover selector, make it visible by changing the opacity value.

#mouse_over {_x000D_
  opacity: 0;_x000D_
}_x000D_
_x000D_
#mouse_over:hover {_x000D_
  opacity: 1;_x000D_
}

<div style='border: 5px solid black; width: 120px; font-family: sans-serif'>_x000D_
<div style='height: 20px; width: 120px; background-color: cyan;' id='mouse_over'>Now you see me</div>_x000D_
</div>

It is clear from the error.

The HtmlHelpers appended with "For" expects lambda expression as a parameter.

If you are passing the value directly, better use Normal one.

e.g.

Instead of TextboxFor(....) use Textbox()

syntax for TextboxFor will be like Html.TextBoxFor(m=>m.Property)

In your scenario you can use basic for loop, as it will give you index to use.

@for(int i=0;i<Model.Theme.Count;i++)
 {
   @Html.LabelFor(m=>m.Theme[i].name)
   @for(int j=0;j<Model.Theme[i].Products.Count;j++) )
     {
      @Html.LabelFor(m=>m.Theme[i].Products[j].name)
      @for(int k=0;k<Model.Theme[i].Products[j].Orders.Count;k++)
          {
           @Html.TextBoxFor(m=>Model.Theme[i].Products[j].Orders[k].Quantity)
           @Html.TextAreaFor(m=>Model.Theme[i].Products[j].Orders[k].Note)
           @Html.EditorFor(m=>Model.Theme[i].Products[j].Orders[k].DateRequestedDeliveryFor)
      }
   }
}

When adding a directory to github check that the directory does not contain a .git file using "ls -a" if it does remove it. .git files in a directory will cause problems when you are trying to add a that directory in git

HTML Elements

An HTML element usually consists of a start tag and end tag, with the content inserted in between:

<tagname>Content goes here...</tagname>

The HTML element is everything from the start tag to the end tag. Source

HTML Attributes

An attribute is used to define the characteristics of an HTML element and is placed inside the element's opening tag. All attributes are made up of two parts: a name and a value.

• All HTML elements can have attributes
• Attributes provide additional information about an element
• Attributes are always specified in the start tag
• Attributes usually come in name/value pairs like: name="value" Source

HTML Tag vs Element

"Elements" and "tags" are terms that are widely confused. HTML documents contain tags, but do not contain the elements. The elements are only generated after the parsing step, from these tags. Source: wikipedia > HTML_element

An HTML element is defined by a starting tag. If the element contains other content, it ends with a closing tag.

For example <p> is starting tag of a paragraph and </p> is closing tag of the same paragraph but <p>This is paragraph</p> is a paragraph element.

If you are using PyQt, then for normal work, you should add "shell":"true" value, this looks like:

{
  "cmd": ["c:/Python32/python.exe", "-u", "$file"],
  "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
  "selector": "source.python",
  "shell":"true"
}

Try putting double quotes in your filepath variable

"\"E:/ABC/SEM 2/testfiles/all.txt\""

Check the permissions of the file or in any case consider renaming the folder to remove the space

There's a much simpler decision.

@app.route('/x')
def x():
    return render_template('test.html', foo=y)

def y(text):
    return text

Then, in test.html:

{{ foo('hi') }}

=iferror(counta(unique(A1:A100))) counts number of unique cells from A1 to A100

Not sure this is what you're looking for, but I had a bit different goal is to check if remote image exists and I will not have 403 error, so you could use something like below:

public static boolean linkExists(String URLName){
    try {
        HttpURLConnection.setFollowRedirects(false);
        HttpURLConnection con = (HttpURLConnection) new URL(URLName).openConnection();
        con.setRequestMethod("HEAD");
        return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
    }
    catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

To have global constants in my apps, this is what I do in a separate Swift file:

import Foundation

struct Config {
    static let baseURL = "https://api.com"

    static APIKeys {
        static let token = "token"
        static let user = "user"
    }

    struct Notifications {
        static let awareUser = "aware_user"
    }
}

It's easy to use, and to call everywhere like this:

print(Config.Notifications.awareUser)

OK.. We needed to compare a dynamic number of product names...

There's probably a better way... but this works for me...

... because....Strings are just Arrays of characters.... :>}

//  Compare Strings ...  Return Matching Text and Differences with Product IDs...

//  From MySql...
$productID1 = 'abc123';
$productName1 = "EcoPlus Premio Jet 600";   

$productID2 = 'xyz789';
$productName2 = "EcoPlus Premio Jet 800";   

$ProductNames = array(
    $productID1 => $productName1,
    $productID2 => $productName2
);


function compareNames($ProductNames){   

    //  Convert NameStrings to Arrays...    
    foreach($ProductNames as $id => $product_name){
        $Package1[$id] = explode(" ",$product_name);    
    }

    // Get Matching Text...
    $Matching = call_user_func_array('array_intersect', $Package1 );
    $MatchingText = implode(" ",$Matching);

    //  Get Different Text...
    foreach($Package1 as $id => $product_name_chunks){
        $Package2 = array($product_name_chunks,$Matching);
        $diff = call_user_func_array('array_diff', $Package2 );
        $DifferentText[$id] = trim(implode(" ", $diff));
    }

    $results[$MatchingText]  = $DifferentText;              
    return $results;    
}

$Results =  compareNames($ProductNames);

print_r($Results);

// Gives us this...
[EcoPlus Premio Jet] 
        [abc123] => 600
        [xyz789] => 800

It's just what it says:

inputFile = open((x), encoding = "utf8", "r")

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

I also found myself in a similar position a couple of weeks ago. You can also do this by creating a custom ElementLocatorFactory (or simply passing in divA into the DefaultElementLocatorFactory) to see if it's a child of the first div - you would then call the appropriate PageFactory initElements method.

In this case if you did the following:

PageFactory.initElements(new DefaultElementLocatorFactory(divA), pageObjectInstance));
// The Page Object instance would then need a WebElement 
// annotated with something like the xpath above or @FindBy(tagName = "input")

try this:

public int getRandomNumber(int min, int max) {
    return (int) Math.floor(Math.random() * (max - min + 1)) + min;
}

lines is a list of strings, re.findall doesn't work with that. try:

import re, sys

f = open('findallEX.txt', 'r')
lines = f.read()
match = re.findall('[A-Z]+', lines)
print match

For me upgrading to version 3.7 of NUnit worked.

I might be late in the game, but how about:

public event Action<MyEvent> EventTriggered = delegate { }; 

private void Trigger(MyEvent e) 
{ 
     EventTriggered(e);
} 

Setting the event to an anonymous delegate avoids for me to check to see if the event isn't null.

I find this comes in handy when using MVVM, like when using ICommand.CanExecute Method.

It happens that I'm just starting to learn coding and I needed something similar as you have just asked in SQLite (I´m using [SQLiteStudio] (3.1.1)).

It happens that you must define the column's 'Constraint' as 'Not Null' then entering your desired definition using 'Default' 'Constraint' or it will not work (I don't know if this is an SQLite or the program requirment).

Here is the code I used:

CREATE TABLE <MY_TABLE> (
<MY_TABLE_KEY>       INTEGER    UNIQUE
                                PRIMARY KEY,
<MY_TABLE_SERIAL>    TEXT       DEFAULT (<MY_VALUE>) 
                                NOT NULL
<THE_REST_COLUMNS>
);

I took a combo of all answers, and now have two ways of doing this with the ng-model attribute:

• With a new scope which copies ngModel
• With the same scope which does a compile on link

I'm not sure I like the compiling at link time. However, if you're just replacing the element with another you don't need to do that.

All in all I prefer the first one. Simply set scope to {ngModel:"="} and set ng-model="ngModel" where you want it in your template.

Update: I inlined the code snippet and updated it for Angular v1.2. Turns out that isolate scope is still best, especially when not using jQuery. So it boils down to:

• Are you replacing a single element: Just replace it, leave the scope alone, but note that replace is deprecated for v2.0:

  app.directive('myReplacedDirective', function($compile) {
    return {
      restrict: 'E',
      template: '<input class="some">',
      replace: true
    };
  });
  

• Otherwise use this:

  app.directive('myDirectiveWithScope', function() {
    return {
      restrict: 'E',
      scope: {
        ngModel: '=',
      },
      template: '<div class="some"><input ng-model="ngModel"></div>'
    };
  });
  

If you want it really easy and a joy to automate, check out Chocolatey.org/install and you can basically copy and paste these commands and tweak it based on what versions of VC++ you need.

This command is taken from https://chocolatey.org/install

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Once you have chocolatey installed you can either close and reopen your Powershell terminal or run this command:

Import-Module "$env:ChocolateyInstall\helpers\chocolateyInstaller.psm1" ; Update-SessionEnvironment

Now you can use Chocolatey to install Python (latest version of 3.x is default).

choco install python

# This next command installs the latest VisualStudio installer that lets you get specific versions of the build
# Microsoft has replaced the 2015 and 2017 installer links with this one, and we can still use it to install the 2015 and 2017 components

choco install visualstudio2019buildtools --package-parameters "--add Microsoft.VisualStudio.Component.VC.140 --passive --locale en-US --add Microsoft.VisualStudio.Component.Windows10SDK.$($PSVersionTable.BuildVersion.Build) --no-includeRecommended" -y --timeout 0

# Usually need the "unlimited" timeout aka "0" because Visual Studio Installer takes forever

# Tool portion
# Microsoft.VisualStudio.Product.BuildTools
# Component portion(s)
# Microsoft.VisualStudio.Component.VC.140
# Win10SDK needs to match your current Win10 build version
# $($PSVersionTable.BuildVersion.Build)
# Microsoft.VisualStudio.Component.Windows10SDK.$($PSVersionTable.BuildVersion.Build)

# Because VS2019 Build Tools are dumb, need to manually link a couple files between the SDK and the VC++ dirs
# You may need to tweak the version here, but it has been updated to be as dynamic as possible 
# Use an elevated Powershell or elevated cmd prompt (if using cmd.exe just use the bits after /c)
cmd /c mklink "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\rc.exe" "C:\Program Files (x86)\Windows Kits\10\bin\$($PSVersionTable.BuildVersion.Major).$($PSVersionTable.BuildVersion.Minor).$($PSVersionTable.BuildVersion.Build).0\x64\rc.exe"

cmd /c mklink "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\rcdll.dll" "C:\Program Files (x86)\Windows Kits\10\bin\$($PSVersionTable.BuildVersion.Major).$($PSVersionTable.BuildVersion.Minor).$($PSVersionTable.BuildVersion.Build).0\x64\rcdll.dll"

Once you have this installed, you should reboot. I've occasionally had things work without a reboot, but your pip install commands will work best if you reboot first.

Now you can pip install pipenv or pip install complex-package and should be good to go.

For some reason, I need float property of a pseudo-element to be set to left or right for the image to appear. height and width of the pseudo-element should be both set but not in percentage. I'm on Firefox 67.

Here's a creative idea using box-shadow:

#header {
    background-image: url("apple.jpg");
    box-shadow: inset 0 0 99999px rgba(0, 120, 255, 0.5);
}

What's happening

1. The background sets the background for your element.

2. The box-shadow is the important bit. It basically sets a really big shadow on the inside of the element, on top of the background, that is semi-transparent

Here's another native PHP based option: https://github.com/2createStudio/shuttle-export

I realize this is a bit late, but I've had success with annotating a timestamp column with

@Column(name="timestamp", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")

This should also work with CURRENT_DATE and CURRENT_TIME. I'm using JPA/Hibernate with Oracle, so YMMV.

Small enhancement to perfectly valid @hmjd's answer: you can use following syntax:

class A {

  final Set<String> strings = new HashSet<>() {{
    add("val1");
    add("val2");
  }};

  // ...

  if (strings.contains(str.toLowerCase())) {
  }

  // ...
}

It allows you to initialize you Set in-place.

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

You can convert a numpy array to list and get its index .

for example:

tmp = [1,2,3,4,5] #python list
a = numpy.array(tmp) #numpy array
i = list(a).index(2) # i will return index of 2, which is 1

this is just what you wanted.

Unfortunately this is invalid HTML. An ID has to be unique in the whole HTML file.

When you use Javascript's document.getElementById() it depends on the browser, which element it will return, mostly it's the first with a given ID.

You will have no other chance as to re-assign your IDs, or alternatively using the class attribute.

First congrats that managed to figure out lambda. In my opinion this is really powerful construct to act with. The trend these days towards functional programming languages is surely an indicator that it neither should be avoided nor it will be redefined in the near future.

You just have to think a little bit different. I'm sure soon you will love it. But be careful if you deal only with python. Because the lambda is not a real closure, it is "broken" somehow: pythons lambda is broken

From W3C Document Object Model (Core) Level 1 specification (bold is mine):

Most of the APIs defined by this specification are interfaces rather than classes. That means that an actual implementation need only expose methods with the defined names and specified operation, not actually implement classes that correspond directly to the interfaces. This allows the DOM APIs to be implemented as a thin veneer on top of legacy applications with their own data structures, or on top of newer applications with different class hierarchies. This also means that ordinary constructors (in the Java or C++ sense) cannot be used to create DOM objects, since the underlying objects to be constructed may have little relationship to the DOM interfaces. The conventional solution to this in object-oriented design is to define factory methods that create instances of objects that implement the various interfaces. In the DOM Level 1, objects implementing some interface "X" are created by a "createX()" method on the Document interface; this is because all DOM objects live in the context of a specific Document.

AFAIK, you can not create any XmlNode (XmlElement, XmlAttribute, XmlCDataSection, etc) except XmlDocument from a constructor.

Moreover, note that you can not use XmlDocument.AppendChild() for nodes that are not created via the factory methods of the same document. In case you have a node from another document, you must use XmlDocument.ImportNode().

You will always have to iterate. Yet you can use Java 8, 9 to do the counting without looping explicitely:

Iterable<Integer> newIterable = () -> iter;
long count = StreamSupport.stream(newIterable.spliterator(), false).count();

Here is a test:

public static void main(String[] args) throws IOException {
    Iterator<Integer> iter = Arrays.asList(1, 2, 3, 4, 5).iterator();
    Iterable<Integer> newIterable = () -> iter;
    long count = StreamSupport.stream(newIterable.spliterator(), false).count();
    System.out.println(count);
}

This prints:

5

Interesting enough you can parallelize the count operation here by changing the parallel flag on this call:

long count = StreamSupport.stream(newIterable.spliterator(), *true*).count();

You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.

Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.

Here is a working code I have written for you:

https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27

In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.

I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file): Percentage (%) = 100 x partial value / total value

It automatically calculates the total and pourcentage even if you add more categories.

I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:

var trace1 = {
    x: xValue, 
    y: data,
    type: 'bar',
    text: yValue,
    textposition: 'auto',
    hoverinfo: 'none',
    marker: {
    color: 'yellow',
    opacity: 0.6,
    line: {
      color: 'yellow',
      width: 1.5
    }
  }
};

It is rather self explanatory, the text is where you put the percentage.

Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:

I know it is an old post but I hope it helps people with the same problem !

The slidingExpiration=true value is basically saying that after every request made, the timer is reset and as long as the user makes a request within the timeout value, he will continue to be authenticated.

This is not correct. The authentication cookie timeout will only be reset if half the time of the timeout has passed.

See for example https://support.microsoft.com/de-ch/kb/910439/en-us or https://itworksonmymachine.wordpress.com/2008/07/17/forms-authentication-timeout-vs-session-timeout/

I use Spring Boot, my solution to the problem was

Hope it helps someone.

In AngularJS, we update our models, and our views/templates update the DOM "automatically" (via built-in or custom directives).

$apply and $watch, both being Scope methods, are not related to the DOM.

The Concepts page (section "Runtime") has a pretty good explanation of the $digest loop, $apply, the $evalAsync queue and the $watch list. Here's the picture that accompanies the text:

Whatever code has access to a scope – normally controllers and directives (their link functions and/or their controllers) – can set up a "watchExpression" that AngularJS will evaluate against that scope. This evaluation happens whenever AngularJS enters its $digest loop (in particular, the "$watch list" loop). You can watch individual scope properties, you can define a function to watch two properties together, you can watch the length of an array, etc.

When things happen "inside AngularJS" – e.g., you type into a textbox that has AngularJS two-way databinding enabled (i.e., uses ng-model), an $http callback fires, etc. – $apply has already been called, so we're inside the "AngularJS" rectangle in the figure above. All watchExpressions will be evaluated (possibly more than once – until no further changes are detected).

When things happen "outside AngularJS" – e.g., you used bind() in a directive and then that event fires, resulting in your callback being called, or some jQuery registered callback fires – we're still in the "Native" rectangle. If the callback code modifies anything that any $watch is watching, call $apply to get into the AngularJS rectangle, causing the $digest loop to run, and hence AngularJS will notice the change and do its magic.

So, after update I had the same issue. I was using PEM key_file without extension and simply adding .pem fixed my issue. Now the file is key_file.pem.

Flow the flowing steps :

1. Edit your listener.ora and tnsnames.ora file in $Oracle_home\product\11.2.0\client_1\NETWORK\ADMIN location

   a. add listener.ora file

   LISTENER =
     (DESCRIPTION_LIST =
       (DESCRIPTION =
         (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
         (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
   )
   

   )

ADR_BASE_LISTENER = C: [here c is oralce home directory]

b. add in tnsnames.ora file

    SCHEMADEV =
            (DESCRIPTION =
                     (ADDRESS_LIST =
                     (ADDRESS = (PROTOCOL = TCP)(HOST = dabase_ip)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = SCHEMADEV)
    )
  )

2. Open command prompt and type
   sqlplus username/passowrd@oracle_connection_alias

Example :
username : your_database_username
password : Your_database_password
oracle_connection_alias : SCHEMADEV for above example.

I want to complete the answer from tchester.

(1) Enable the xp_cmdshell procedure:

-- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO

-- Enable the xp_cmdshell procedure
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE
GO

(2) Create a login 'Domain\TestUser' (windows user) for the non-sysadmin user that has public access to the master database

(3) Grant EXEC permission on the xp_cmdshell stored procedure:

GRANT EXECUTE ON xp_cmdshell TO [Domain\TestUser]

(4) Create a proxy account that xp_cmdshell will be run under using sp_xp_cmdshell_proxy_account

EXEC sp_xp_cmdshell_proxy_account 'Domain\TestUser', 'pwd'
-- Note: pwd means windows password for [Domain\TestUser] account id on the box.
--       Don't include square brackets around Domain\TestUser.

(5) Grant control server permission to user

USE master;
GRANT CONTROL SERVER TO [Domain\TestUser]
GO

You can even nest document ready functions inside included html files. Here's an example using jquery:

File: test_main.html

<!DOCTYPE html>
<html lang="en">
<head>
    <script src="jquery-1.10.2.min.js"></script>
</head>

<body>
    <div id="main-container">
        <h1>test_main.html</h1>
    </div>

<script>
    $(document).ready( function()
    {
        console.log( 'test_main.html READY' );
        $("#main-container").load("test_embed.html");
    } );
</script>

</body>
</html>

File: test_embed.html

<h1>test_embed.html</h1>
<script>
    $(document).ready( function()
    {
        console.log( 'test_embed.html READY' );
    } );
</script>

Console output:

test_main.html READY                       test_main.html:15
test_embed.html READY                      (program):4

Browser shows:

test_embed.html

Another way is to use np.place which does in-place replacement and works with multidimentional arrays:

import numpy as np

# create 2x3 array with numbers 0..5
arr = np.arange(6).reshape(2, 3)

# replace 0 with -10
np.place(arr, arr == 0, -10)

void foo<TOne, TTwo>() 
   where TOne : BaseOne
   where TTwo : BaseTwo

More info here:
http://msdn.microsoft.com/en-us/library/d5x73970.aspx

Try to use:

location.reload(true);

When this method receives a true value as argument, it will cause the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.

More info:

• The location object

$('#id').attr('onclick', 'function()');

Right now (11 Jul 2015) this solution is still working (jquery 2.1.4); in my opinion, it is the best one to pick up.

You can improve the speed of your code if you restrict the items jQuery will look at.

Use the selector :input instead of * to achieve it.

$('#divId :input').serialize()

This will make your code faster because the list of items is shorter.

You can use inotifywait (with the modify,create,delete,move flags enabled) and rsync.

while inotifywait -r -e modify,create,delete,move /directory; do
    rsync -avz /directory /target
done

If you don't have inotifywait on your system, run sudo apt-get install inotify-tools

I did it like this. hope this will help you.

              <div *ngIf="passmsg != '' && !addAdminForm.controls?.confPass?.errors?.required">
                <p class="errorMsg">*{{passmsg}}</p>
              </div>  
            </div>
          </div>
      </form>

TS File :

export class AddAdminAccountsComponent implements OnInit {

  addAdminForm: FormGroup;
  password: FormControl;
  confPass: FormControl;
  passmsg: string;


  constructor(
    private http: HttpClient,
    private router: Router,

  ngOnInit() {    
    this.createFormGroup();
  }



    // |---------------------------------------------------------------------------------------

    createFormGroup() {    
      this.addAdminForm = new FormGroup({
        password: new FormControl('', [Validators.required]),
        confPass: new FormControl('', [Validators.required]),
      })
    }



    // |---------------------------------------------------------------------------------------

    // |---------------------------------------------------------------------------------------

    checkPassSame() {
      let pass = this.addAdminForm.value.password;
      let passConf = this.addAdminForm.value.confPass;
      if(pass == passConf && this.addAdminForm.valid === true) {
        this.passmsg = "";
        return false;
      }else {
        this.passmsg = "Password did not match.";
        return true;
      }
    }



}

I recommended using the size function.

class Customer < ActiveRecord::Base
  has_many :customer_activities
end

class CustomerActivity < ActiveRecord::Base
  belongs_to :customer, counter_cache: true
end

Consider these two models. The customer has many customer activities.

If you use a :counter_cache on a has_many association, size will use the cached count directly, and not make an extra query at all.

Consider one example: in my database, one customer has 20,000 customer activities and I try to count the number of records of customer activities of that customer with each of count, length and size method. here below the benchmark report of all these methods.

            user     system      total        real
Count:     0.000000   0.000000   0.000000 (  0.006105)
Size:      0.010000   0.000000   0.010000 (  0.003797)
Length:    0.030000   0.000000   0.030000 (  0.026481)

so I found that using :counter_cache Size is the best option to calculate the number of records.

You can directly give the source property of the current object in the img src attribute. Please see my code below:

<div *ngFor="let brochure of brochureList">
    <img class="brochure-poster" [src]="brochure.imageUrl" />
</div>

NOTE: You can as well use string interpolation but that is not a legit way to do it. Property binding was created for this very purpose hence better use this.

NOT RECOMMENDED :

<img class="brochure-poster" src="{{brochure.imageUrl}}"/>

Its because that defeats the purpose of property binding. It is more meaningful to use that for setting the properties. {{}} is a normal string interpolation expression, that does not reveal to anyone reading the code that it makes special meaning. Using [] makes it easily to spot the properties that are set dynamically.

Here is my brochureList contains the following json received from service(you can assign it to any variable):

[ {
            "productId":1,
            "productName":"Beauty Products",
            "productCode": "XXXXXX",            
            "description":  "Skin Care",           
            "imageUrl":"app/Images/c1.jpg"
         },
        {
             "productId":2,
            "productName":"Samsung Galaxy J5",
            "productCode": "MOB-124",      
            "description":  "8GB, Gold",
            "imageUrl":"app/Images/c8.jpg"
         }]

The query below returns the timezone of the current session.

select timediff(now(),convert_tz(now(),@@session.time_zone,'+00:00'));

There's no direct equivalent of "friend" - the closest that's available (and it isn't very close) is InternalsVisibleTo. I've only ever used this attribute for testing - where it's very handy!

Example: To be placed in AssemblyInfo.cs

[assembly: InternalsVisibleTo("OtherAssembly")]

I wanted to give some kudos to the comment that mentioned CTRL + Z as an option. At the end of the day, it's going to depend on what system that you have Git installed on and what program is configured to open text files (e.g. less vs. vim). CTRL + Z works for vim on Windows.

If you're using Git in a Windows environment, there are some quirks. Just helps to know what they are. (i.e. Notepad vs. Nano, etc.).

The lambda you are passing to forEach() is evaluated for each element received from the stream. The iteration itself is not visible from within the scope of the lambda, so you cannot continue it as if forEach() were a C preprocessor macro. Instead, you can conditionally skip the rest of the statements in it.

You could also just create a Group Policy Preference and have it create the reg key for you. (no scripting involved)

A hacky one-liner for 2.5+ :

>>> a = dict(x=2, y=3)
>>> b = dict(y=4, z=5)
>>> c = 'No Effect' if a.update(b) else a
>>> c
{'x': 2, 'y': 4, 'z': 5}

Things to keep in mind:

• dict.update modifies the dict in-place, hence it evaluates to None
• In expression A if C else B, C is evaluated first. See here

So here, a.update(b) is evaluated first, a gets updated with b and operation results in None, thus the expression will always return the value given in the else condition, i.e. a. Since, a is already modified, it will return the new value of a, which is the updated dict.

IMPROVEMENT

This can be further improved, and it be made to work for even older versions (probably python 1.0 as well?):

>>> c = a.update(b) or a

Here also, the first part produces None, hence it always returns the second part, but as the update operation is already done, it always returns the updated dict.

CRITIQUE

• Both the solution modify the value of a, so if one wants to keep both the input dictionaries unchanged, this is not a good idea.

IMPROVEMENT

If copy of a is needed, the second one can be slightly modified:

>>> a = dict(x=2, y=3)
>>> b = dict(y=4, z=5)
>>> a, c = a.copy(), a.update(b) or a
>>> c
{'x': 2, 'y': 4, 'z': 5}
>>> d = dict(m=10, n=11)
>>> a, c = a.copy(), a.update(b) or a.update(d) or a
>>> c
{'x': 2, 'y': 4, 'z': 5, 'm': 10, 'n': 11}
>>> a
{'x': 2, 'y': 4}

CAVEATS

• It (especially the first one) gets ugly and impractical for any number of dicts greater than 2
• Furthermore, this is not explicit, which is un-pythonic.

Even though these solutions are extremely fast, especially the or method which is probably faster than the new python 3.9 union operator (not entirely sure, further testing required, if anyone wants to add it afterwards, they are welcome), I would not recommend these methods due to the abovementioned reasons. Added it for the sake of completeness.

arrowdodger's answer is correct and preferred on many occasions. I would simply like to add an alternative to his answer:

You could add an "imported" library target, instead of a link-directory. Something like:

# Your-external "mylib", add GLOBAL if the imported library is located in directories above the current.
add_library( mylib SHARED IMPORTED )
# You can define two import-locations: one for debug and one for release.
set_target_properties( mylib PROPERTIES IMPORTED_LOCATION ${CMAKE_BINARY_DIR}/res/mylib.so )

And then link as if this library was built by your project:

TARGET_LINK_LIBRARIES(GLBall mylib)

Such an approach would give you a little more flexibility: Take a look at the add_library( ) command and the many target-properties related to imported libraries.

I do not know if this will solve your problem with "updated versions of libs".

Command-line approach

mkdir android-sdk
cd android-sdk
wget https://dl.google.com/android/repository/sdk-tools-linux-*.zip
unzip sdk-tools-linux-*.zip
tools/bin/sdkmanager --update

When executing the above commands, make sure that you replace * with an appropriate version number which you could find in the download page.

Installing packages

You can also use the sdkmanager to list and to install any specific packages needed.

tools/bin/sdkmanager --list
tools/bin/sdkmanager "platform-tools" "platforms;android–27" "build-tools;27.0.3"

FYI

sdk-tools-linux-*.zip only includes the command-line tools. This extracts content to a single directory named tools, like:

+- android-sdk
    +- tools

To get the SDK packages we could run:

tools/bin/sdkmanager --update

The sdkmanager accepts the following flag:

--sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK 
                          containing this tool

But if we omit this flag, it assumes parent directory of tools directory as the sdk root, here in our case android-sdk directory.

If you check the android-sdk folder after running tools/bin/sdkmanager --update it will be like:

+- android-sdk
    +- tools
    +- emulator  
    +- platforms  
    +- platform-tool

If needed, also set ANDROID_HOME environment variable like:

export ANDROID_HOME=/path/to/android-sdk

This is Kohana's implementation, you could use it:

public static function bytes($bytes, $force_unit = NULL, $format = NULL, $si = TRUE)
{
    // Format string
    $format = ($format === NULL) ? '%01.2f %s' : (string) $format;

    // IEC prefixes (binary)
    if ($si == FALSE OR strpos($force_unit, 'i') !== FALSE)
    {
        $units = array('B', 'KiB', 'MiB', 'GiB', 'TiB', 'PiB');
        $mod   = 1024;
    }
    // SI prefixes (decimal)
    else
    {
        $units = array('B', 'kB', 'MB', 'GB', 'TB', 'PB');
        $mod   = 1000;
    }

    // Determine unit to use
    if (($power = array_search((string) $force_unit, $units)) === FALSE)
    {
        $power = ($bytes > 0) ? floor(log($bytes, $mod)) : 0;
    }

    return sprintf($format, $bytes / pow($mod, $power), $units[$power]);
}

React Version 0.62.1

In your root project directory

Make sure you have already directory android/app/src/main/assets/, if not create directory, after that create new file and save as index.android.bundle and put your file in like this android/app/src/main/assets/index.android.bundle

After that run this

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

cd android && ./gradlew assembleDebug

Then you can get apk in app/build/outputs/apk/debug/app-debug.apk

As the documentation says, this method call returns "a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive)". This means that you will get numbers from 0 to 9 in your case. So you've done everything correctly by adding one to that number.

Generally speaking, if you need to generate numbers from min to max (including both), you write

random.nextInt(max - min + 1) + min

If by join you mean union, try this:

set(list(s) + list(t))

It's a bit of a hack, but I can't think of a better one liner to do it.

the solution to the typescript:

Step1:

npm install jquery

npm install --save-dev @types/jquery

step2: in Angular.json add:

"scripts": [
        "node_modules/jquery/dist/jquery.min.js",
      ]

or in index.html add:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

step3: in *.component.ts where you want to use jquery

import * as $ from 'jquery';  // dont need "declare let $"

Then you can use jquery the same as javaScript. This way, VScode supports auto-suggestion by Typescript

Try this code using the hostip.info service:

$country=file_get_contents('http://api.hostip.info/get_html.php?ip=');
echo $country;

// Reformat the data returned (Keep only country and country abbr.)
$only_country=explode (" ", $country);

echo "Country : ".$only_country[1]." ".substr($only_country[2],0,4);

Remove YouTube Branding

To date: Seeing a lot of searches and suggestions to disable YouTube logo and branding from an embedded video; I recommend you consider the following:

1. I guess YouTube don't want you to do this otherwise they would allow that at their front end.
2. Some brands spending huge efforts to provide the media not for a 5 min. removal.
3. It's good to have the logo and respects brands rights.
4. You still have the video and the luxury of embedding it in your site/blog.
5. Spare some of your time; that is not possible.

6. Yet! You have the option of having Modest-Branding using this parameters:

   https://www.youtube.com/embed/'+videourl+'?modestbranding=1

And some other parameters for customization:

&showinfo=0 //Turn off Title & Ratings

&showsearch=0 //Turn off Search

&rel=1 //Turn on Related Videos

&iv_load_policy=3 //Turn off Annotations

&cc_load_policy=1 //Force Closed Captions

&autoplay=1 //Turn on AutoPlay (not recommended)

&loop=1 //Loop Playback

&fs=0 //Remove Full Screen Option (not sure why you’d want to)

And here is the general customization window:

^{Disclaimer: I don't work for YouTube; simply I respect the copyrights.}

#! /bin/bash

function do_something {
   echo value=${1}
}

MAX=4
for (( i=0; i<MAX; i++ )) ; {
   do_something ${i}
}

Here's an example that can also work in older shells, while still being efficient for large counts:

Z=$(date) awk 'BEGIN { for ( i=0; i<4; i++ ) { print i,"hello",ENVIRON["Z"]; } }'

But good luck doing useful things inside of awk: How do I use shell variables in an awk script?

Edit: my bad, you wanted the select to show results after the update, not update from a select.

Have you tried a sub-select?

update mytable set mydate = sysdate 
where mydate in (select mydate from mytable where mydate is null);

You could also use

ImageIcon background = new ImageIcon("Background/background.png");
JLabel label = new JLabel();
label.setBounds(0, 0, x, y);
label.setIcon(background);

JPanel panel = new JPanel();
panel.setLayout(null);
panel.add(label);

if your working with a absolut value as layout.

That's unnecessary. Just use SELECT CONVERT(column USING utf8) FROM..... instead of just SELECT column FROM...

In Python there's no POSIX regex classes

There are when using the regex library: https://pypi.org/project/regex/

It is well maintained and supports Unicode regex, Posix regex and many more. The usage (method signatures) is very similar to Python's re.

From the documentation:

[[:alpha:]]; [[:^alpha:]]

POSIX character classes are supported. These are normally treated as an alternative form of \p{...}.

I spent half a week trying to figure this out myself, and wrote a whole article on it, https://github.com/latitov/OOP_MI_Ct_oPlus_in_JS, and hope it helps some of you.

In short, here's how MI can be implemented in JavaScript:

    class Car {
        constructor(brand) {
            this.carname = brand;
        }
        show() {
            return 'I have a ' + this.carname;
        }
    }

    class Asset {
        constructor(price) {
            this.price = price;
        }
        show() {
            return 'its estimated price is ' + this.price;
        }
    }

    class Model_i1 {        // extends Car and Asset (just a comment for ourselves)
        //
        constructor(brand, price, usefulness) {
            specialize_with(this, new Car(brand));
            specialize_with(this, new Asset(price));
            this.usefulness = usefulness;
        }
        show() {
            return Car.prototype.show.call(this) + ", " + Asset.prototype.show.call(this) + ", Model_i1";
        }
    }

    mycar = new Model_i1("Ford Mustang", "$100K", 16);
    document.getElementById("demo").innerHTML = mycar.show();

And here's specialize_with() one-liner:

function specialize_with(o, S) { for (var prop in S) { o[prop] = S[prop]; } }

Again, please look at https://github.com/latitov/OOP_MI_Ct_oPlus_in_JS.

sure you can do that without using any addition, just pure javascript, by using this method of dns browser.dns.resolve("example.com"); but it is compatible just with FIREFOX 60 you can see more information on MDN https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/dns/resolve

Try using itertools.count([n])

Actually I don't know what is the reason exactly, I have faced this like of problem. if you have the domain's IP address (ex 208.113.139.4), please use the IP address instead of domain (in this case www.icerts.com)

wget 192.243.111.11/images/logo.jpg

Go to find the IP from URL https://ipinfo.info/html/ip_checker.php

Javascript has a function just for that: Array.prototype.find. As example

function isBigEnough(element) {
  return element >= 15;
}

[12, 5, 8, 130, 44].find(isBigEnough); // 130

It not difficult to extends the callback to a function. However this is not compatible with IE (and partially with Edge). For a full list look at the Browser Compatibility

I installed the Tensorflow 0.12rc from source, and the following command gives me the version info:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 2
python3 -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 3

The following figure shows the output:

Will need to save the beginning center of the image view:

var panBegin: CGPoint.zero

Then update the new center using a transform:

if recognizer.state == .began {
     panBegin = imageView!.center

} else if recognizer.state == .ended {
    panBegin = CGPoint.zero

} else if recognizer.state == .changed {
    let translation = recognizer.translation(in: view)
    let panOffsetTransform = CGAffineTransform( translationX: translation.x, y: translation.y)

    imageView!.center = panBegin.applying(panOffsetTransform)
}

Assuming you are using PHP5.3 then the modern way of handling dates is via the native DateTime class. To get the current time you can just call

$currentTime = new DateTime();

To create a DateTime object from a specific timestamp (i.e. not now)

$currentTime = DateTime::createFromFormat( 'U', $timestamp );

To get a formatted string you can then call

$formattedString = $currentTime->format( 'c' );

See the manual page here

I'm late to the party, but searching for the correct way to do it I came across this page it was one of the top Google search returns, so I will like to share my view on the problem, which I consider it to be up to date at the time of writing this post (beginning of 2017). From PHP 7.1.0 the mcrypt_decrypt and mcrypt_encrypt is going to be deprecated, so building future proof code should use openssl_encrypt and openssl_decrypt

You can do something like:

$string_to_encrypt="Test";
$password="password";
$encrypted_string=openssl_encrypt($string_to_encrypt,"AES-128-ECB",$password);
$decrypted_string=openssl_decrypt($encrypted_string,"AES-128-ECB",$password);

Important: This uses ECB mode, which isn't secure. If you want a simple solution without taking a crash course in cryptography engineering, don't write it yourself, just use a library.

You can use any other chipper methods as well, depending on your security need. To find out the available chipper methods please see the openssl_get_cipher_methods function.

If you are managing the Hibernate session manually, you may want to look into sessionFactory.getCurrentSession() and associated docs here:

http://www.hibernate.org/hib_docs/v3/reference/en/html/architecture-current-session.html

Change the line where you print the output to:

printf("\nmaximum of %d and %d is = %d",a,b,c);

See the docs here

To set JDK you can watch this video : how to set JDK . Then when you'll have JDK:

1. Right click on build path and select "Build Path"
2. Choose "Configure Build Path"
3. Click on "JRE System Library [JavaSE-1.7] (unbound)"
4. Edit it
5. Choose "Alternate JRE"
6. Click on "Installed JREs.." button
7. Press Add
8. Choose to add "Standard VM"
9. Choose JRE Home directory - usually it is locates in "C:\Program Files\Java\jre7" directory
10. Press "Finish"
11. Re-check newly appeared "Jre7": Verify that now when you edit "JRE System Library [JavaSE-1.7]" "Alternate JRE" is chosen for jre7.
