In latest versions of mysql, at least in mine, you cannot put your pass in the command directly.

You have to run:

mysqldump -u [uname] -p db_name > db_backup.sql

and then it will ask for the password.

The possibility could be, the SSH might not be enabled on your server/system.

1. Check sudo systemctl status ssh is Active or not.
2. If it's not active, try installing with the help of these commands

sudo apt update

sudo apt install openssh-server

Now try to access the server/system with following command

ssh username@ip_address

Where is this list of products that you're trying to determine the existence of? If that list exists within another table you could do this

declare @are_equal bit
declare @products int

SELECT @products = 
     count(pl.id)
FROM ProductList pl
JOIN Products p
ON pl.productId = p.productId

select @are_equal = @products == select count(id) from ProductList

Edit:

Then do ALL the work in C#. Cache the actual list of products in your application somewhere, and do a LINQ query.

var compareProducts = new List<Product>(){p1,p2,p3,p4,p5};
var found = From p in GetAllProducts()
            Join cp in compareProducts on cp.Id equals p.Id
            select p;

return compareProducts.Count == found.Count;

This prevents constructing SQL queries by hand, and keeps all your application logic in the application.

In a GET request, you pass parameters as part of the query string.

string url = "http://somesite.com?var=12345";

The notation that is used in

a[::-1]

means that for a given string/list/tuple, you can slice the said object using the format

<object_name>[<start_index>, <stop_index>, <step>]

This means that the object is going to slice every "step" index from the given start index, till the stop index (excluding the stop index) and return it to you.

In case the start index or stop index is missing, it takes up the default value as the start index and stop index of the given string/list/tuple. If the step is left blank, then it takes the default value of 1 i.e it goes through each index.

So,

a = '1234'
print a[::2]

would print

13

Now the indexing here and also the step count, support negative numbers. So, if you give a -1 index, it translates to len(a)-1 index. And if you give -x as the step count, then it would step every x'th value from the start index, till the stop index in the reverse direction. For example

a = '1234'
print a[3:0:-1]

This would return

432

Note, that it doesn't return 4321 because, the stop index is not included.

Now in your case,

str(int(a[::-1]))

would just reverse a given integer, that is stored in a string, and then convert it back to a string

i.e "1234" -> "4321" -> 4321 -> "4321"

If what you are trying to do is just reverse the given string, then simply a[::-1] would work .

public class StaticMethod{

    public static void main(String []args)throws Exception{
        methodOne();
    }

    public int methodOne(){
        System.out.println("we are in first methodOne");
        return 1;
    }
}

the above code not executed because static method must have that class reference.

public class StaticMethod{
    public static void main(String []args)throws Exception{

        StaticMethod sm=new StaticMethod();
        sm.methodOne();
    }

    public int methodOne(){
        System.out.println("we are in first methodOne");
        return 1;
    }
}

This will be definitely get executed. Because here we are creating reference which nothing but "sm" by using that reference of that class which is nothing but (StaticMethod=new Static method()) we are calling method one (sm.methodOne()).

I hope this will be helpful.

It's not exactly clear how you want to search the array. Here are some alternatives:

Find all items containing the exact string "Ra" (returns items 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.Contains("Ra"))

Find all items starting with the exact string "Ra" (returns items 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.StartsWith("Ra"))

Find all items containing any case version of "ra" (returns items 0, 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.ToLower().Contains("ra"))

Find all items starting with any case version of "ra" (retuns items 0, 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.ToLower().StartsWith("ra"))

-

If you are not using VB 9+ then you don't have anonymous functions, so you have to create a named function.

Example:

Function ContainsRa(s As String) As Boolean
   Return s.Contains("Ra")
End Function

Usage:

Dim result As String() = Array.FindAll(arr, ContainsRa)

Having a function that only can compare to a specific string isn't always very useful, so to be able to specify a string to compare to you would have to put it in a class to have somewhere to store the string:

Public Class ArrayComparer

   Private _compareTo As String

   Public Sub New(compareTo As String)
      _compareTo = compareTo
   End Sub

   Function Contains(s As String) As Boolean
      Return s.Contains(_compareTo)
   End Function

   Function StartsWith(s As String) As Boolean
      Return s.StartsWith(_compareTo)
   End Function

End Class

Usage:

Dim result As String() = Array.FindAll(arr, New ArrayComparer("Ra").Contains)

If the two databases are on the same server, you should be able to create a SQL statement something like this:

UPDATE Test1.dbo.Employee
SET DeptID = emp2.DeptID
FROM Test2.dbo.Employee as 'emp2'
WHERE
   Test1.dbo.Employee.EmployeeID = emp2.EmployeeID

From your post, I'm not quite clear whether you want to update Test1.dbo.Employee with the values from Test2.dbo.Employee (that's what my query does), or the other way around (since you mention the db on Test1 was the new table......)

Sorry, I didn't notice the PHP tag - however someone else might be interested in a VB solution:

Module Module1

    Sub Main()
        Dim d As Date = Now
        Dim nextFriday As Date = DateAdd(DateInterval.Weekday, DayOfWeek.Friday - d.DayOfWeek(), Now)
        Console.WriteLine("next friday is " & nextFriday)
        Console.ReadLine()
    End Sub

End Module

You can use the attribute if you want your code to do overloading.

[ActionName("MyOverloadedName")]

But, you'll have to use a different action name for the same http method (as others have said). So it's just semantics at that point. Would you rather have the name in your code or your attribute?

Phil has an article related to this: http://haacked.com/archive/2008/08/29/how-a-method-becomes-an-action.aspx

Move points into test:

def test():
    points = 0
    addpoint = raw_input ("type ""add"" to add a point")
    ...

or use global statement, but it is bad practice. But better way it move points to parameters:

def test(points=0):
    addpoint = raw_input ("type ""add"" to add a point")
    ...

There's a Python module that you can get from PyPI called progressbar that implements such functionality. If you don't mind adding a dependency, it's a good solution. Otherwise, go with one of the other answers.

A simple example of how to use it:

import progressbar
from time import sleep
bar = progressbar.ProgressBar(maxval=20, \
    widgets=[progressbar.Bar('=', '[', ']'), ' ', progressbar.Percentage()])
bar.start()
for i in xrange(20):
    bar.update(i+1)
    sleep(0.1)
bar.finish()

To install it, you can use easy_install progressbar, or pip install progressbar if you prefer pip.

Properties are used to encapsulate some data. You could use a plain field:

public string MyField

But this field can be accessed by all outside users of your class. People can insert illegal values or change the value in ways you didn't expect.

By using a property, you can encapsulate the way your data is accessed. C# has a nice syntax for turning a field into a property:

string MyProperty { get; set; }

This is called an auto-implemented property. When the need arises you can expand your property to:

string _myProperty;

public string MyProperty
{
    get { return _myProperty; }
    set { _myProperty = value; }
}

Now you can add code that validates the value in your setter:

set
{
    if (string.IsNullOrWhiteSpace(value))
        throw new ArgumentNullException();

    _myProperty = value;
}

Properties can also have different accessors for the getter and the setter:

public string MyProperty { get; private set; }

This way you create a property that can be read by everyone but can only be modified by the class itself.

You can also add a completely custom implementation for your getter:

public string MyProperty
{
    get
    {
        return DateTime.Now.Second.ToString();
    }
}

When C# compiles your auto-implemented property, it generates Intermediate Language (IL). In your IL you will see a get_MyProperty and set_MyProperty method. It also creates a backing field called <MyProperty>k_BackingField (normally this would be an illegal name in C# but in IL it's valid. This way you won't get any conflicts between generated types and your own code). However, you should use the official property syntax in C#. This creates a nicer experience in C# (for example with IntelliSense).

By convention, you shouldn't use properties for operations that take a long time.

As gradle built-in tasks is deprecated in 4.8, try below

wrapper {
   gradleVersion = '2.0' //version required
}

and run

gradle wrapper

Some notes that I also found useful:

• Keep your default values on the right side.

  function whatever($var1, $var2, $var3="constant", $var4="another")
  

• The default value of the argument must be a constant expression. It can't be a variable or a function call.

Actually, you are looking for the AJAX CALL, in which you will replace the URL parameter value with the link of the JSON file to get the JSON values.

$.ajax({
    url: "File.json", //the path of the file is replaced by File.json
    dataType: "json",
    success: function (response) {
        console.log(response); //it will return the json array
    }
});

This works:

var img = document.createElement('img');
img.src = 'img/eqp/' + this.apparel + '/' + this.facing + '_idle.png';
document.getElementById('gamediv').appendChild(img)

Or using jQuery:

$('<img/>')
.attr('src','img/eqp/' + this.apparel + '/' + this.facing + '_idle.png')
.appendTo('#gamediv');

A LEFT JOIN is absolutely not faster than an INNER JOIN. In fact, it's slower; by definition, an outer join (LEFT JOIN or RIGHT JOIN) has to do all the work of an INNER JOIN plus the extra work of null-extending the results. It would also be expected to return more rows, further increasing the total execution time simply due to the larger size of the result set.

(And even if a LEFT JOIN were faster in specific situations due to some difficult-to-imagine confluence of factors, it is not functionally equivalent to an INNER JOIN, so you cannot simply go replacing all instances of one with the other!)

Most likely your performance problems lie elsewhere, such as not having a candidate key or foreign key indexed properly. 9 tables is quite a lot to be joining so the slowdown could literally be almost anywhere. If you post your schema, we might be able to provide more details.

Edit:

Reflecting further on this, I could think of one circumstance under which a LEFT JOIN might be faster than an INNER JOIN, and that is when:

• Some of the tables are very small (say, under 10 rows);
• The tables do not have sufficient indexes to cover the query.

Consider this example:

CREATE TABLE #Test1
(
    ID int NOT NULL PRIMARY KEY,
    Name varchar(50) NOT NULL
)
INSERT #Test1 (ID, Name) VALUES (1, 'One')
INSERT #Test1 (ID, Name) VALUES (2, 'Two')
INSERT #Test1 (ID, Name) VALUES (3, 'Three')
INSERT #Test1 (ID, Name) VALUES (4, 'Four')
INSERT #Test1 (ID, Name) VALUES (5, 'Five')

CREATE TABLE #Test2
(
    ID int NOT NULL PRIMARY KEY,
    Name varchar(50) NOT NULL
)
INSERT #Test2 (ID, Name) VALUES (1, 'One')
INSERT #Test2 (ID, Name) VALUES (2, 'Two')
INSERT #Test2 (ID, Name) VALUES (3, 'Three')
INSERT #Test2 (ID, Name) VALUES (4, 'Four')
INSERT #Test2 (ID, Name) VALUES (5, 'Five')

SELECT *
FROM #Test1 t1
INNER JOIN #Test2 t2
ON t2.Name = t1.Name

SELECT *
FROM #Test1 t1
LEFT JOIN #Test2 t2
ON t2.Name = t1.Name

DROP TABLE #Test1
DROP TABLE #Test2

If you run this and view the execution plan, you'll see that the INNER JOIN query does indeed cost more than the LEFT JOIN, because it satisfies the two criteria above. It's because SQL Server wants to do a hash match for the INNER JOIN, but does nested loops for the LEFT JOIN; the former is normally much faster, but since the number of rows is so tiny and there's no index to use, the hashing operation turns out to be the most expensive part of the query.

You can see the same effect by writing a program in your favourite programming language to perform a large number of lookups on a list with 5 elements, vs. a hash table with 5 elements. Because of the size, the hash table version is actually slower. But increase it to 50 elements, or 5000 elements, and the list version slows to a crawl, because it's O(N) vs. O(1) for the hashtable.

But change this query to be on the ID column instead of Name and you'll see a very different story. In that case, it does nested loops for both queries, but the INNER JOIN version is able to replace one of the clustered index scans with a seek - meaning that this will literally be an order of magnitude faster with a large number of rows.

So the conclusion is more or less what I mentioned several paragraphs above; this is almost certainly an indexing or index coverage problem, possibly combined with one or more very small tables. Those are the only circumstances under which SQL Server might sometimes choose a worse execution plan for an INNER JOIN than a LEFT JOIN.

After adding curl.exe's path to the System Variable 'Path'

you can open command prompt and run 'curl -V' to see if it is working.

$.ajax({
  url: "target.php",
  type: "post",
  data: "fname="+fname+"&lname="+lname,
}).done(function(data) {
  alert(data);
});

You need to add it to providers array, which includes all depency on your component.

Look at this section in angular documentation:

Registering providers in a component

Here's a revised HeroesComponent that registers the HeroService in its providers array.

import { Component } from '@angular/core';

import { HeroService } from './hero.service';

@Component({
  selector: 'my-heroes',
  providers: [HeroService],
  template: `
  <h2>Heroes</h2>
  <hero-list></hero-list>
  `
})
export class HeroesComponent { }

When to use NgModule versus an application component

On the one hand, a provider in an NgModule is registered in the root injector. That means that every provider registered within an NgModule will be accessible in the entire application.

On the other hand, a provider registered in an application component is available only on that component and all its children.

Here, the APP_CONFIG service needs to be available all across the application, so it's registered in the AppModule @NgModule providers array. But since the HeroService is only used within the Heroes feature area and nowhere else, it makes sense to register it in the HeroesComponent.

Also see "Should I add app-wide providers to the root AppModule or the root AppComponent?" in the NgModule FAQ.

So in your case, simply change injectables to providers like below:

@Component({
  selector: 'my-app',
  providers: [NameService]
})

Also in the new versions of Angular, @View and some other stuffs gone.

Check out new Tool bar on support library class in Lollipop update you can design actionbar by adding toolbar in your layout

add these items in your app theme

 <item name="android:windowNoTitle">true</item>
 <item name="windowActionBar">false</item>

Create your toolbar in a layout and include your textview in center design your toolbar

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/acbarcolor">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/toolbar_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:text="@string/app_name"
            android:textColor="#ffffff"
            android:textStyle="bold" />

    </RelativeLayout>

</android.support.v7.widget.Toolbar>

add your action bar as tool bar

toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

please ensure that you need to include toolbar on your resource file like this

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    android:orientation="vertical"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <include
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        layout="@layout/toolbar" />

    <android.support.v4.widget.DrawerLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <!-- Framelayout to display Fragments -->
        <FrameLayout
            android:id="@+id/frame_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <include
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                layout="@layout/homepageinc" />

        </FrameLayout>

        <fragment
            android:id="@+id/fragment1"
            android:layout_gravity="start"
            android:name="com.shouldeye.homepages.HomeFragment"
            android:layout_width="250dp"
            android:layout_height="match_parent" />

    </android.support.v4.widget.DrawerLayout>

</LinearLayout>

Why don't you just write an empty method in Person and override it in the children classes? And call it, when it needs to be:

void caluculate(Person p){
  p.dotheCalculate();
}

This would mean you have to have the same method in both children classes, but i don't see why this would be a problem at all.

In addition, for those looking to replace more than one character in a column, you can do it using regular expressions:

import re
chars_to_remove = ['.', '-', '(', ')', '']
regular_expression = '[' + re.escape (''. join (chars_to_remove)) + ']'

df['string_col'].str.replace(regular_expression, '', regex=True)

Another option is just using head:

grep ...parameters... yourfile | head

This won't require searching the entire file - it will stop when the first ten matching lines are found. Another advantage with this approach is that will return no more than 10 lines even if you are using grep with the -o option.

For example if the file contains the following lines:

112233
223344
123123

Then this is the difference in the output:

$ grep -o '1.' yourfile | head -n2
11
12

$ grep -m2 -o '1.'
11
12
12

Using head returns only 2 results as desired, whereas -m2 returns 3.

The more efficient (less obtrusive) way of doing this is through custom formatting.

1. Highlight the column/array you want to style.
2. Click ctrl + 1 or Format -> Format Cells.
3. In the Number tab, choose Custom.
4. Set the Custom formatting to 000#. (zero zero zero #)

Note that this does not actually change the value of the cell. It only displays the leading zeroes in the worksheet.

The following will display all 3 buttons on the same line provided there is enough horizontal space to display them:

<button type="submit" class="msgBtn" onClick="return false;" >Save</button>
<button type="submit" class="msgBtn2" onClick="return false;">Publish</button>
<button class="msgBtnBack">Back</button>
// Note the lack of unnecessary divs, floats, etc. 

The only reason the buttons wouldn't display inline is if they have had display:block applied to them within your css.

1.get all tables and views from information_schema.tables, include those of information_schema and pg_catalog.

select * from information_schema.tables

2.get tables and views belong certain schema

select * from information_schema.tables
    where table_schema not in ('information_schema', 'pg_catalog')

3.get tables only(almost \dt)

select * from information_schema.tables
    where table_schema not in ('information_schema', 'pg_catalog') and
    table_type = 'BASE TABLE'

This is a classpath issue when running an executable jar as follows:

java -jar myfile.jar

One way to fix the problem is to set the classpath on the java command line as follows, adding the missing log4j jar:

java -cp myfile.jar:log4j.jar:otherjar.jar com.abc.xyz.MyMainClass

Of course the best solution is to add the classpath into the jar manifest so that the we can use the "-jar" java option:

<jar jarfile="myfile.jar">
    ..
    ..
    <manifest>
       <attribute name="Main-Class" value="com.abc.xyz.MyMainClass"/>
       <attribute name="Class-Path" value="log4j.jar otherjar.jar"/>
    </manifest>
</jar>

The following answer demonstrates how you can use the manifestclasspath to automate the seeting of the classpath manifest entry

From documentation:

Matplotlib can only read PNGs natively. Further image formats are supported via the optional dependency on Pillow.

So in case of PNG we may use plt.imread(). In other cases it's probably better to use Pillow directly.

The cause of your problems is that you are trying to do a cross-domain call and it fails.

If you're doing localhost development you can make cross-domain calls - I do it all the time.

For Firefox, you have to enable it in your config settings

signed.applets.codebase_principal_support = true

Then add something like this to your XHR open code:

  if (isLocalHost()){
    if (typeof(netscape) != 'undefined' && typeof(netscape.security) != 'undefined'){
      netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
    }
  }

For IE, if I remember right, all you have to do is enable the browser's Security setting under "Miscellaneous → Access data sources across domains" to get it to work with ActiveX XHRs.

IE8 and above also added cross-domain capabilities to the native XmlHttpRequest objects, but I haven't played with those yet.

if (rs == null || !rs.first()) {
    //empty
} else {
    //not empty
}

Note that after this method call, if the resultset is not empty, it is at the beginning.

I think this is due to the connection established with the client machine is not secure.

It is due to the fact that you are talking to an HTTP server, not an HTTPS server. Probably you didn't use the correct port number for HTTPS.

Today there are four font container formats in use on the web: EOT, TTF, WOFF,andWOFF2.

Unfortunately, despite the wide range of choices, there isn't a single universal format that works across all old and new browsers:

• EOT is IE only,
• TTF has partial IE support,
• WOFF enjoys the widest support but is not available in some older browsers
• WOFF 2.0 support is a work in progress for many browsers.

If you want your web app to have the same font across all browsers then you might want to provide all 4 font type in CSS

 @font-face {
      font-family: 'besom'; !important
      src: url('fonts/besom/besom.eot');
      src: url('fonts/besom/besom.eot?#iefix') format('embedded-opentype'),
           url('fonts/besom/besom.woff2') format('woff2'),
           url('fonts/besom/besom.woff') format('woff'),
           url('fonts/besom/besom.ttf') format('truetype'),
           url('fonts/besom/besom.svg#besom_2regular') format('svg');
      font-weight: normal;
      font-style: normal;
  }

Or, if spacing is not the problem, it might want the parent directory name rather than the file name.

These are some tips to make your cells Bold, Big font, Italic

Let's say I have columns from A to L

A1 - is your starting cell

L1 - is your last cell

$objPHPExcel->getActiveSheet()->getStyle('A1:L1')->getFont()->setBold(true);
$objPHPExcel->getActiveSheet()->getStyle('A1:L1')->getFont()->setSize(16);
$objPHPExcel->getActiveSheet()->getStyle('A1:L1')->getFont()->setItalic(true);

You can put it in a different class and then call a function. This works when ajax refresh

$(document).on("change", ".inputQty", function(e) {

//Call a function(input,input);
});

js version, catches iPad too:

var is_mobile = /mobile|android/i.test (navigator.userAgent);

You might be able to make use of the Async.js Waterfall feature - see the bottom part of the big code chunk in Step 3 of this document for an example:

Use parameter expansion, if the value is already stored in a variable.

$ str="GenFiltEff=7.092200e-01"
$ value=${str#*=}

Or use read

$ IFS="=" read name value <<< "GenFiltEff=7.092200e-01"

Either way,

$ echo $value
7.092200e-01

assuming certain column names...

INSERT one

newToner = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

dbsession.add(newToner)   
dbsession.commit()

INSERT multiple

newToner1 = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

newToner2 = Toner(toner_id = 2,
                    toner_color = 'red',
                    toner_hex = '#F01731')

dbsession.add_all([newToner1, newToner2])   
dbsession.commit()

UPDATE

q = dbsession.query(Toner)
q = q.filter(Toner.toner_id==1)
record = q.one()
record.toner_color = 'Azure Radiance'

dbsession.commit()

or using a fancy one-liner using MERGE

record = dbsession.merge(Toner( **kwargs))

You can use it by easy way, through store method in your controller

like the below

First, we must create a form with file input to let us upload our file.

{{Form::open(['route' => 'user.store', 'files' => true])}}

{{Form::label('user_photo', 'User Photo',['class' => 'control-label'])}}
{{Form::file('user_photo')}}
{{Form::submit('Save', ['class' => 'btn btn-success'])}}

{{Form::close()}}

Here is how we can handle file in our controller.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class UserController extends Controller
{

  public function store(Request $request)
  {

  // get current time and append the upload file extension to it,
  // then put that name to $photoName variable.
  $photoName = time().'.'.$request->user_photo->getClientOriginalExtension();

  /*
  talk the select file and move it public directory and make avatars
  folder if doesn't exsit then give it that unique name.
  */
  $request->user_photo->move(public_path('avatars'), $photoName);

  }
}

That’s it. Now you can save the $photoName to the database as a user_photo field value. You can use asset(‘avatars’) function in your view and access the photos.

You cannot directly use a SQL statement in a PL/SQL expression:

SQL> begin
  2     if (select count(*) from dual) >= 1 then
  3        null;
  4     end if;
  5  end;
  6  /
        if (select count(*) from dual) >= 1 then
            *
ERROR at line 2:
ORA-06550: line 2, column 6:
PLS-00103: Encountered the symbol "SELECT" when expecting one of the following:
...
...

You must use a variable instead:

SQL> set serveroutput on
SQL>
SQL> declare
  2     v_count number;
  3  begin
  4     select count(*) into v_count from dual;
  5
  6     if v_count >= 1 then
  7             dbms_output.put_line('Pass');
  8     end if;
  9  end;
 10  /
Pass

PL/SQL procedure successfully completed.

Of course, you may be able to do the whole thing in SQL:

update my_table
set x = y
where (select count(*) from other_table) >= 1;

It's difficult to prove that something is not possible. Other than the simple test case above, you can look at the syntax diagram for the IF statement; you won't see a SELECT statement in any of the branches.

When there is a conflict during a merge, you have to finish the merge commit manually. It sounds like you've done the first two steps, to edit the files that conflicted and then run git add on them to mark them as resolved. Finally, you need to actually commit the merge with git commit. At that point you will be able to switch branches again.

We can iterate object using in keyword and can perform any arithmetic operation.

// input
const sample = {
    'a': 1,
    'b': 2,
    'c': 3
};

// var
let sum = 0;

// object iteration
for (key in sample) {
    //sum
    sum += (+sample[key]);
}
// result
console.log("sum:=>", sum);

Enter the following commands:

adb kill-server
sudo ./adb start-server
adb devices

This happens when you are not running adb server as root.

ls -tQ | tail -n+4 | xargs rm

List filenames by modification time, quoting each filename. Exclude first 3 (3 most recent). Remove remaining.

EDIT after helpful comment from mklement0 (thanks!): corrected -n+3 argument, and note this will not work as expected if filenames contain newlines and/or the directory contains subdirectories.

You just try this, Its so easy

 <script>

  $("#YourDropDownId").change(function () {
            alert($("#YourDropDownId").val());
        });

</script>

For SSMS 18, I found the files at:

C:\Users\YourUserName\Documents\Visual Studio 2017\Backup Files\Solution1

For SSMS 17, It was used to be at:

C:\Users\YourUserName\Documents\Visual Studio 2015\Backup Files\Solution1

If you don't want to integrate a framework like Zend, then you can use the trigger_error method to log to the php error log.

Something like this, I think. find_if_counted.hpp:

#define FIND_IF_COUNTED_HPP

#include <algorithm>

namespace find_if_counted_impl

    template <typename Func>
    struct func_counter

        explicit func_counter(Func& func, unsigned &count) :
        _func(func),
        _count(count)
        {
        }

        template <typename T>
        bool operator()(const T& t)
        {
            ++_count;

            return _func(t);
        }

    private:
        Func& _func;
        unsigned& _count;
    };
}

// generic find_if_counted,

    InputIterator result = find_if(start, finish, f);

    if (result == finish)
    {
        return find_if_not_found;
    }
    else
    {
        return count - 1;
    }
}

#endif

Example:

#include "find_if_counted.hpp"
#include <cstdlib>
#include <iostream>
#include <vector>

typedef std::vector<int> container;

int rand_number(void)
{
    return rand()  % 20;

bool is_even(int i)

            " vec2's corresponding number is: " << vec2[index] << std::endl;

}

Though I feel like I'm doing something silly... :X Any corrections are welcome, of course.

Loop over the file to read lines:

with open('somefile') as openfileobject:
    for line in openfileobject:
        do_something()

File objects are iterable and yield lines until EOF. Using the file object as an iterable uses a buffer to ensure performant reads.

You can do the same with the stdin (no need to use raw_input():

import sys

for line in sys.stdin:
    do_something()

To complete the picture, binary reads can be done with:

from functools import partial

with open('somefile', 'rb') as openfileobject:
    for chunk in iter(partial(openfileobject.read, 1024), b''):
        do_something()

where chunk will contain up to 1024 bytes at a time from the file, and iteration stops when openfileobject.read(1024) starts returning empty byte strings.

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".

Sub test()
    dbWb = Application.ActiveWorkbook.FullName
    dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2"  'Data2 is a named range


sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command

dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon

dbCommand.CommandText = sCommand
dbCommand.Execute

dbCon.Close


End Sub

Step1

In your Dockerfile, you can use the verb EXPOSE to expose multiple ports.
e.g.

EXPOSE 3000 80 443 22

Step2

You then would like to build an new image based on above Dockerfile.
e.g.

docker build -t foo:tag .

Step3

Then you can use the -p to map host port with the container port, as defined in above EXPOSE of Dockerfile.
e.g.

docker run -p 3001:3000 -p 23:22

In case you would like to expose a range of continuous ports, you can run docker like this:

docker run -it -p 7100-7120:7100-7120/tcp 

This is not how SQL works:

INSERT INTO employee(hans,germany) values(?,?)

The values (hans,germany) should use column names (emp_name, emp_address). The values are provided by your program by using the Statement.setString(pos,value) methods. It is complaining because you said there were two parameters (the question marks) but didn't provide values.

You should be creating a PreparedStatement and then setting parameter values as in:

String insert= "INSERT INTO employee(emp_name,emp_address) values(?,?)";
PreparedStatement stmt = con.prepareStatement(insert);
stmt.setString(1,"hans");
stmt.setString(2,"germany");
stmt.execute();

I'm not entirely certain that this applies to Scala but, in Java, I solved the NotSerializableException by refactoring my code so that the closure did not access a non-serializable final field.

The structure of your menu code is the issue:

cin >> choice;   // new line character is left in the stream

 switch ( ... ) {
     // We enter the handlers, '\n' still in the stream
 }

cin.ignore();   // Put this right after cin >> choice, before you go on
                // getting input with getline.

If you are setting the contents of IFrame using javascript document.write() then you must close the document by newWin.document.close(); otherwise the following code will not work and print will print the contents of whole page instead of only the IFrame contents.

var frm = document.getElementById(id).contentWindow;
frm.focus();// focus on contentWindow is needed on some ie versions
frm.print();

The \caption command is restricted to floats: you will need to place the equation in a figure or table environment (or a new kind of floating environment). For example:

\begin{figure}
\[ E = m c^2 \]
\caption{A famous equation}
\end{figure}

The point of floats is that you let LaTeX determine their placement. If you want to equation to appear in a fixed position, don't use a float. The \captionof command of the caption package can be used to place a caption outside of a floating environment. It is used like this:

\[ E = m c^2 \]
\captionof{figure}{A famous equation}

This will also produce an entry for the \listoffigures, if your document has one.

To align parts of an equation, take a look at the eqnarray environment, or some of the environments of the amsmath package: align, gather, multiline,...

If:

> char<-c("one", "two", "three")

You can:

> print(char[1],quote = FALSE)

Your result should be:

[1] one

You can find all of those operators in the Python language reference, though you'll have to scroll around a bit to find them all. As other answers have said:

• The ** operator does exponentiation. a ** b is a raised to the b power. The same ** symbol is also used in function argument and calling notations, with a different meaning (passing and receiving arbitrary keyword arguments).
• The ^ operator does a binary xor. a ^ b will return a value with only the bits set in a or in b but not both. This one is simple!
• The % operator is mostly to find the modulus of two integers. a % b returns the remainder after dividing a by b. Unlike the modulus operators in some other programming languages (such as C), in Python a modulus it will have the same sign as b, rather than the same sign as a. The same operator is also used for the "old" style of string formatting, so a % b can return a string if a is a format string and b is a value (or tuple of values) which can be inserted into a.
• The // operator does Python's version of integer division. Python's integer division is not exactly the same as the integer division offered by some other languages (like C), since it rounds towards negative infinity, rather than towards zero. Together with the modulus operator, you can say that a == (a // b)*b + (a % b). In Python 2, floor division is the default behavior when you divide two integers (using the normal division operator /). Since this can be unexpected (especially when you're not picky about what types of numbers you get as arguments to a function), Python 3 has changed to make "true" (floating point) division the norm for division that would be rounded off otherwise, and it will do "floor" division only when explicitly requested. (You can also get the new behavior in Python 2 by putting from __future__ import division at the top of your files. I strongly recommend it!)

xs:boolean is predefined with regard to what kind of input it accepts. If you need something different, you have to define your own enumeration:

 <xs:simpleType name="my:boolean">
    <xs:restriction base="xs:string">
      <xs:enumeration value="True"/>
      <xs:enumeration value="False"/>
    </xs:restriction>
  </xs:simpleType>

The problem is the use of aspect='equal', which prevents the subplots from stretching to an arbitrary aspect ratio and filling up all the empty space.

Normally, this would work:

import matplotlib.pyplot as plt

ax = [plt.subplot(2,2,i+1) for i in range(4)]

for a in ax:
    a.set_xticklabels([])
    a.set_yticklabels([])

plt.subplots_adjust(wspace=0, hspace=0)

The result is this:

However, with aspect='equal', as in the following code:

import matplotlib.pyplot as plt

ax = [plt.subplot(2,2,i+1) for i in range(4)]

for a in ax:
    a.set_xticklabels([])
    a.set_yticklabels([])
    a.set_aspect('equal')

plt.subplots_adjust(wspace=0, hspace=0)

This is what we get:

The difference in this second case is that you've forced the x- and y-axes to have the same number of units/pixel. Since the axes go from 0 to 1 by default (i.e., before you plot anything), using aspect='equal' forces each axis to be a square. Since the figure is not a square, pyplot adds in extra spacing between the axes horizontally.

To get around this problem, you can set your figure to have the correct aspect ratio. We're going to use the object-oriented pyplot interface here, which I consider to be superior in general:

import matplotlib.pyplot as plt

fig = plt.figure(figsize=(8,8)) # Notice the equal aspect ratio
ax = [fig.add_subplot(2,2,i+1) for i in range(4)]

for a in ax:
    a.set_xticklabels([])
    a.set_yticklabels([])
    a.set_aspect('equal')

fig.subplots_adjust(wspace=0, hspace=0)

Here's the result:

If you don't have to support devices with API < 21, use backgroundHint in xml, for example:

 <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPersonName"
            android:hint="Task Name"
            android:ems="10"
            android:id="@+id/task_name"
            android:layout_marginBottom="15dp"
            android:textAlignment="center"
            android:textColor="@android:color/white"

            android:textColorLink="@color/blue"
            android:textColorHint="@color/blue"
            android:backgroundTint="@color/lighter_blue" />

For better support and fallbacks use @Akariuz solution. backgroundHint is the most painless solution, but not backward compatible, based on your requirements make a call.

You create __main__.py in yourpackage to make it executable as:

$ python -m yourpackage

In binary, 0xE9 looks like 1110 1001. If you read about UTF-8 on Wikipedia, you’ll see that such a byte must be followed by two of the form 10xx xxxx. So, for example:

>>> b'\xe9\x80\x80'.decode('utf-8')
u'\u9000'

But that’s just the mechanical cause of the exception. In this case, you have a string that is almost certainly encoded in latin 1. You can see how UTF-8 and latin 1 look different:

>>> u'\xe9'.encode('utf-8')
b'\xc3\xa9'
>>> u'\xe9'.encode('latin-1')
b'\xe9'

(Note, I'm using a mix of Python 2 and 3 representation here. The input is valid in any version of Python, but your Python interpreter is unlikely to actually show both unicode and byte strings in this way.)

1. Unzip the .ipa file by changing its extension with .zip

Summary (TL;DR)

Updated June 3rd, 2017

Redis is more powerful, more popular, and better supported than memcached. Memcached can only do a small fraction of the things Redis can do. Redis is better even where their features overlap.

For anything new, use Redis.

Memcached vs Redis: Direct Comparison

Both tools are powerful, fast, in-memory data stores that are useful as a cache. Both can help speed up your application by caching database results, HTML fragments, or anything else that might be expensive to generate.

Points to Consider

When used for the same thing, here is how they compare using the original question's "Points to Consider":

• Read/write speed: Both are extremely fast. Benchmarks vary by workload, versions, and many other factors but generally show redis to be as fast or almost as fast as memcached. I recommend redis, but not because memcached is slow. It's not.
• Memory usage: Redis is better.
  • memcached: You specify the cache size and as you insert items the daemon quickly grows to a little more than this size. There is never really a way to reclaim any of that space, short of restarting memcached. All your keys could be expired, you could flush the database, and it would still use the full chunk of RAM you configured it with.
  • redis: Setting a max size is up to you. Redis will never use more than it has to and will give you back memory it is no longer using.
  • I stored 100,000 ~2KB strings (~200MB) of random sentences into both. Memcached RAM usage grew to ~225MB. Redis RAM usage grew to ~228MB. After flushing both, redis dropped to ~29MB and memcached stayed at ~225MB. They are similarly efficient in how they store data, but only one is capable of reclaiming it.
• Disk I/O dumping: A clear win for redis since it does this by default and has very configurable persistence. Memcached has no mechanisms for dumping to disk without 3rd party tools.
• Scaling: Both give you tons of headroom before you need more than a single instance as a cache. Redis includes tools to help you go beyond that while memcached does not.

memcached

Memcached is a simple volatile cache server. It allows you to store key/value pairs where the value is limited to being a string up to 1MB.

It's good at this, but that's all it does. You can access those values by their key at extremely high speed, often saturating available network or even memory bandwidth.

When you restart memcached your data is gone. This is fine for a cache. You shouldn't store anything important there.

If you need high performance or high availability there are 3rd party tools, products, and services available.

redis

Redis can do the same jobs as memcached can, and can do them better.

Redis can act as a cache as well. It can store key/value pairs too. In redis they can even be up to 512MB.

You can turn off persistence and it will happily lose your data on restart too. If you want your cache to survive restarts it lets you do that as well. In fact, that's the default.

It's super fast too, often limited by network or memory bandwidth.

If one instance of redis/memcached isn't enough performance for your workload, redis is the clear choice. Redis includes cluster support and comes with high availability tools (redis-sentinel) right "in the box". Over the past few years redis has also emerged as the clear leader in 3rd party tooling. Companies like Redis Labs, Amazon, and others offer many useful redis tools and services. The ecosystem around redis is much larger. The number of large scale deployments is now likely greater than for memcached.

The Redis Superset

Redis is more than a cache. It is an in-memory data structure server. Below you will find a quick overview of things Redis can do beyond being a simple key/value cache like memcached. Most of redis' features are things memcached cannot do.

Documentation

Redis is better documented than memcached. While this can be subjective, it seems to be more and more true all the time.

redis.io is a fantastic easily navigated resource. It lets you try redis in the browser and even gives you live interactive examples with each command in the docs.

There are now 2x as many stackoverflow results for redis as memcached. 2x as many Google results. More readily accessible examples in more languages. More active development. More active client development. These measurements might not mean much individually, but in combination they paint a clear picture that support and documentation for redis is greater and much more up-to-date.

Persistence

By default redis persists your data to disk using a mechanism called snapshotting. If you have enough RAM available it's able to write all of your data to disk with almost no performance degradation. It's almost free!

In snapshot mode there is a chance that a sudden crash could result in a small amount of lost data. If you absolutely need to make sure no data is ever lost, don't worry, redis has your back there too with AOF (Append Only File) mode. In this persistence mode data can be synced to disk as it is written. This can reduce maximum write throughput to however fast your disk can write, but should still be quite fast.

There are many configuration options to fine tune persistence if you need, but the defaults are very sensible. These options make it easy to setup redis as a safe, redundant place to store data. It is a real database.

Many Data Types

Memcached is limited to strings, but Redis is a data structure server that can serve up many different data types. It also provides the commands you need to make the most of those data types.

Strings (commands)

Simple text or binary values that can be up to 512MB in size. This is the only data type redis and memcached share, though memcached strings are limited to 1MB.

Redis gives you more tools for leveraging this datatype by offering commands for bitwise operations, bit-level manipulation, floating point increment/decrement support, range queries, and multi-key operations. Memcached doesn't support any of that.

Strings are useful for all sorts of use cases, which is why memcached is fairly useful with this data type alone.

Hashes (commands)

Hashes are sort of like a key value store within a key value store. They map between string fields and string values. Field->value maps using a hash are slightly more space efficient than key->value maps using regular strings.

Hashes are useful as a namespace, or when you want to logically group many keys. With a hash you can grab all the members efficiently, expire all the members together, delete all the members together, etc. Great for any use case where you have several key/value pairs that need to grouped.

One example use of a hash is for storing user profiles between applications. A redis hash stored with the user ID as the key will allow you to store as many bits of data about a user as needed while keeping them stored under a single key. The advantage of using a hash instead of serializing the profile into a string is that you can have different applications read/write different fields within the user profile without having to worry about one app overriding changes made by others (which can happen if you serialize stale data).

Lists (commands)

Redis lists are ordered collections of strings. They are optimized for inserting, reading, or removing values from the top or bottom (aka: left or right) of the list.

Redis provides many commands for leveraging lists, including commands to push/pop items, push/pop between lists, truncate lists, perform range queries, etc.

Lists make great durable, atomic, queues. These work great for job queues, logs, buffers, and many other use cases.

Sets (commands)

Sets are unordered collections of unique values. They are optimized to let you quickly check if a value is in the set, quickly add/remove values, and to measure overlap with other sets.

These are great for things like access control lists, unique visitor trackers, and many other things. Most programming languages have something similar (usually called a Set). This is like that, only distributed.

Redis provides several commands to manage sets. Obvious ones like adding, removing, and checking the set are present. So are less obvious commands like popping/reading a random item and commands for performing unions and intersections with other sets.

Sorted Sets (commands)

Sorted Sets are also collections of unique values. These ones, as the name implies, are ordered. They are ordered by a score, then lexicographically.

This data type is optimized for quick lookups by score. Getting the highest, lowest, or any range of values in between is extremely fast.

If you add users to a sorted set along with their high score, you have yourself a perfect leader-board. As new high scores come in, just add them to the set again with their high score and it will re-order your leader-board. Also great for keeping track of the last time users visited and who is active in your application.

Storing values with the same score causes them to be ordered lexicographically (think alphabetically). This can be useful for things like auto-complete features.

Many of the sorted set commands are similar to commands for sets, sometimes with an additional score parameter. Also included are commands for managing scores and querying by score.

Geo

Redis has several commands for storing, retrieving, and measuring geographic data. This includes radius queries and measuring distances between points.

Technically geographic data in redis is stored within sorted sets, so this isn't a truly separate data type. It is more of an extension on top of sorted sets.

Bitmap and HyperLogLog

Like geo, these aren't completely separate data types. These are commands that allow you to treat string data as if it's either a bitmap or a hyperloglog.

Bitmaps are what the bit-level operators I referenced under Strings are for. This data type was the basic building block for reddit's recent collaborative art project: r/Place.

HyperLogLog allows you to use a constant extremely small amount of space to count almost unlimited unique values with shocking accuracy. Using only ~16KB you could efficiently count the number of unique visitors to your site, even if that number is in the millions.

Transactions and Atomicity

Commands in redis are atomic, meaning you can be sure that as soon as you write a value to redis that value is visible to all clients connected to redis. There is no wait for that value to propagate. Technically memcached is atomic as well, but with redis adding all this functionality beyond memcached it is worth noting and somewhat impressive that all these additional data types and features are also atomic.

While not quite the same as transactions in relational databases, redis also has transactions that use "optimistic locking" (WATCH/MULTI/EXEC).

Pipelining

Redis provides a feature called 'pipelining'. If you have many redis commands you want to execute you can use pipelining to send them to redis all-at-once instead of one-at-a-time.

Normally when you execute a command to either redis or memcached, each command is a separate request/response cycle. With pipelining, redis can buffer several commands and execute them all at once, responding with all of the responses to all of your commands in a single reply.

This can allow you to achieve even greater throughput on bulk importing or other actions that involve lots of commands.

Pub/Sub

Redis has commands dedicated to pub/sub functionality, allowing redis to act as a high speed message broadcaster. This allows a single client to publish messages to many other clients connected to a channel.

Redis does pub/sub as well as almost any tool. Dedicated message brokers like RabbitMQ may have advantages in certain areas, but the fact that the same server can also give you persistent durable queues and other data structures your pub/sub workloads likely need, Redis will often prove to be the best and most simple tool for the job.

Lua Scripting

You can kind of think of lua scripts like redis's own SQL or stored procedures. It's both more and less than that, but the analogy mostly works.

Maybe you have complex calculations you want redis to perform. Maybe you can't afford to have your transactions roll back and need guarantees every step of a complex process will happen atomically. These problems and many more can be solved with lua scripting.

The entire script is executed atomically, so if you can fit your logic into a lua script you can often avoid messing with optimistic locking transactions.

Scaling

As mentioned above, redis includes built in support for clustering and is bundled with its own high availability tool called redis-sentinel.

Conclusion

Without hesitation I would recommend redis over memcached for any new projects, or existing projects that don't already use memcached.

The above may sound like I don't like memcached. On the contrary: it is a powerful, simple, stable, mature, and hardened tool. There are even some use cases where it's a little faster than redis. I love memcached. I just don't think it makes much sense for future development.

Redis does everything memcached does, often better. Any performance advantage for memcached is minor and workload specific. There are also workloads for which redis will be faster, and many more workloads that redis can do which memcached simply can't. The tiny performance differences seem minor in the face of the giant gulf in functionality and the fact that both tools are so fast and efficient they may very well be the last piece of your infrastructure you'll ever have to worry about scaling.

There is only one scenario where memcached makes more sense: where memcached is already in use as a cache. If you are already caching with memcached then keep using it, if it meets your needs. It is likely not worth the effort to move to redis and if you are going to use redis just for caching it may not offer enough benefit to be worth your time. If memcached isn't meeting your needs, then you should probably move to redis. This is true whether you need to scale beyond memcached or you need additional functionality.

You have it almost done. Just explicitly say where to create the file

@echo off
  echo.>"d:\testing\dblank.txt"

This creates a file containing a blank line (CR + LF = 2 bytes).

If you want the file empty (0 bytes)

@echo off
  break>"d:\testing\dblank.txt"

I think this might be helpful:

You should have started the mongod instance with access control, i.e., the --auth command line option, such as:

$ mongod --auth

Let's start the mongo shell, and create an administrator in the admin database:

$ mongo
> use admin
> db.createUser(
  {
    user: "myUserAdmin",
    pwd: "abc123",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

Now if you run command "db.stats()", or "show users", you will get error "not authorized on admin to execute command..."

> db.stats()
{
        "ok" : 0,
        "errmsg" : "not authorized on admin to execute command { dbstats: 1.0, scale: undefined }",
        "code" : 13,
        "codeName" : "Unauthorized"
}

The reason is that you still have not granted role "read" or "readWrite" to user myUserAdmin. You can do it as below:

> db.auth("myUserAdmin", "abc123")
> db.grantRolesToUser("myUserAdmin", [ { role: "read", db: "admin" } ])

Now You can verify it (Command "show users" now works):

> show users
{
        "_id" : "admin.myUserAdmin",
        "user" : "myUserAdmin",
        "db" : "admin",
        "roles" : [
                {
                        "role" : "read",
                        "db" : "admin"
                },
                {
                        "role" : "userAdminAnyDatabase",
                        "db" : "admin"
                }
        ]
}

Now if you run "db.stats()", you'll also be OK:

> db.stats()
{
        "db" : "admin",
        "collections" : 2,
        "views" : 0,
        "objects" : 3,
        "avgObjSize" : 151,
        "dataSize" : 453,
        "storageSize" : 65536,
        "numExtents" : 0,
        "indexes" : 3,
        "indexSize" : 81920,
        "ok" : 1
}

This user and role mechanism can be applied to any other databases in MongoDB as well, in addition to the admin database.

(MongoDB version 3.4.3)

You should define the attributes of option like selected="selected"

<select>
   <option selected="selected">a</option>
   <option>b</option>
   <option>c</option>
</select>

It will kill not only all plot windows, but all processes that are called python3, except the current script you run. It works for python3. So, if you are running any other python3 script it will be terminated. As I only run one script at once, it does the job for me.

import os
import subprocess
subprocess.call(["bash","-c",'pyIDs=($(pgrep python3));for x in "${pyIDs[@]}"; do if [ "$x" -ne '+str(os.getpid())+' ];then  kill -9 "$x"; fi done'])

This can be more complicated than it looks depending on how you want to count things. For instance, if you have a list of ints, do you want the size of the list containing the references to the ints? (ie. list only, not what is contained in it), or do you want to include the actual data pointed to, in which case you need to deal with duplicate references, and how to prevent double-counting when two objects contain references to the same object.

You may want to take a look at one of the python memory profilers, such as pysizer to see if they meet your needs.

Depends on what it means that the object is not found.

If it's a normal state of affairs, then return null. This is just something that might happen once in an while, and the callers should check for it.

If it's an error, then throw an exception, the callers should decide what to do with the error condition of missing object.

Ultimately either would work, although most people generally consider it good practice to only use Exceptions when something, well, Exceptional has happened.

You can use the lineTo() method same as: var objctx = canvas.getContext('2d');

        objctx.beginPath();
        objctx.moveTo(75, 50);
        objctx.lineTo(175, 50);
        objctx.lineTo(200, 75);
        objctx.lineTo(175, 100);
        objctx.lineTo(75, 100);
        objctx.lineTo(50, 75);
        objctx.closePath();
        objctx.fillStyle = "rgb(200,0,0)";
        objctx.fill();

if you not want to fill the polygon use the stroke() method in the place of fill()

You can extend jQuery prototype and use your function as a jQuery method.

(function($)
{
    $.fn.MyBlah = function(blah)
    {
        $(this).addClass(blah);
        console.log('blah class added');
    };
})(jQuery);

jQuery(document).ready(function($)
{
    $('#blahElementId').MyBlah('newClass');
});

More info on extending jQuery prototype here: http://api.jquery.com/jquery.fn.extend/

Answered here quite elegantly using attached behaviors, my preferred method for almost anything.

WPF how to make textbox lose focus after hitting enter

This is the one that works for me:

SELECT DISTINCT 
    local_tcp_port 
FROM sys.dm_exec_connections 
WHERE local_tcp_port IS NOT NULL 

You want set_ticks_position rather than set_label_position:

ax.xaxis.set_ticks_position('top') # the rest is the same

This gives me:

What you are after is called partial function application.

Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.

Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:

Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.

This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?

Example:

var fr = partial(f, 1, 2, 3);

// now, when you invoke fr() it will invoke f(1,2,3)
fr();

Again, see that question for the details.

YouTube supports a fairly easy to use iframe and url interface to embed videos, playlists and all user uploads to your channel: https://developers.google.com/youtube/player_parameters

For example this HTML will embed a player loaded with a playlist of all the videos uploaded to your channel. Replace YOURCHANNELNAME with the actual name of your channel:

<iframe src="http://www.youtube.com/embed/?listType=user_uploads&list=YOURCHANNELNAME" width="480" height="400"></iframe>

You should put your model class before create_all() call, like this:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    email = db.Column(db.String(120), unique=True)

    def __init__(self, username, email):
        self.username = username
        self.email = email

    def __repr__(self):
        return '<User %r>' % self.username

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

If your models are declared in a separate module, import them before calling create_all().

Say, the User model is in a file called models.py,

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

# See important note below
from models import User

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

Important note: It is important that you import your models after initializing the db object since, in your models.py _you also need to import the db object from this module.

tr can be more concise for removing characters than sed or awk, especially when you want to remove different characters from a string.

Removing double quotes:

echo '"Hi"' | tr -d \"
# Produces Hi without quotes

Removing different kinds of brackets:

echo '[{Hi}]' | tr -d {}[]
# Produces Hi without brackets

-d stands for "delete".

This error occurred for me when using window.location.reload(). Replacing with window.location = window.location.href solved the problem.

Internet Explorer specific, but rather good:

http://pamie.sourceforge.net/

The advantage compared to urllib/BeautifulSoup is that it executes Javascript as well since it uses IE.

The accepted answer offers a solution which requires changing of the underlying data frame. This is not necessary. One can also simply factorise within the aes() call directly or create a vector for that instead.

This is certainly not much different than user Drew Steen's answer, but with the important difference of not changing the original data frame.

level_order <- c('virginica', 'versicolor', 'setosa') #this vector might be useful for other plots/analyses

ggplot(iris, aes(x = factor(Species, level = level_order), y = Petal.Width)) + geom_col()

or

level_order <- factor(iris$Species, level = c('virginica', 'versicolor', 'setosa'))

ggplot(iris, aes(x = level_order, y = Petal.Width)) + geom_col()

or
directly in the aes() call without a pre-created vector:

ggplot(iris, aes(x = factor(Species, level = c('virginica', 'versicolor', 'setosa')), y = Petal.Width)) + geom_col()

Using console.log(object) will throw your object to the Javascript console, but that's not always what you want. Using JSON.stringify(object) will return most stuff to be stored in a variable, for example to send it to a textarea input and submit the content back to the server.

The best way to set/get the value of a textarea is the .val(), .value method.

.text() internally uses the .textContent (or .innerText for IE) method to get the contents of a <textarea>. The following test cases illustrate how text() and .val() relate to each other:

var t = '<textarea>';
console.log($(t).text('test').val());             // Prints test
console.log($(t).val('too').text('test').val());  // Prints too
console.log($(t).val('too').text());              // Prints nothing
console.log($(t).text('test').val('too').val());  // Prints too

console.log($(t).text('test').val('too').text()); // Prints test

The value property, used by .val() always shows the current visible value, whereas text()'s return value can be wrong.

Due to behavior "smooth" doesn't work in Safari, Safari ios, Explorer. I usually write a simple function utilizing requestAnimationFrame

(function(){
    var start;
    var startPos = 0;

    //Navigation scroll page to element
    function scrollTo(timestamp, targetTop){
      if(!start) start = timestamp
      var runtime = timestamp - start
      var progress = Math.min(runtime / 700, 1)

      window.scroll(0, startPos + (targetTop * progress) )

      if(progress >= 1){
        return;
      }else {
        requestAnimationFrame(function(timestamp){
            scrollTo(timestamp, targetTop)
        })
      }
   };

  navElement.addEventListener('click', function(e){

    var target = e.target  //or this 
    var targetTop = _(target).getBoundingClientRect().top
    startPos = window.scrollY

    requestAnimationFrame(function(timestamp){
        scrollTo(timestamp, targetTop)
    })
  }

})();

PHP 7 improved query.........

I have used Mockito.verify in this way

@UnitTest
public class JUnitServiceTest
{
    @Mock
    private MyCustomService myCustomService;


    @Test
    public void testVerifyMethod()
    {
       Mockito.verify(myCustomService, Mockito.never()).mymethod(parameters); // method will never call (an alternative can be pick to use times(0))
       Mockito.verify(myCustomService, Mockito.times(2)).mymethod(parameters); // method will call for 2 times
       Mockito.verify(myCustomService, Mockito.atLeastOnce()).mymethod(parameters); // method will call atleast 1 time
       Mockito.verify(myCustomService, Mockito.atLeast(2)).mymethod(parameters); // method will call atleast 2 times
       Mockito.verify(myCustomService, Mockito.atMost(3)).mymethod(parameters); // method will call at most 3 times
       Mockito.verify(myCustomService, Mockito.only()).mymethod(parameters); //   no other method called except this
    }
}

You can open default sms App and pass details as below :
Note : If u want to send to many numbers, separate each number with ";" inside string

String mblNumVar = "9876543210;9123456789";
Intent smsMsgAppVar = new Intent(Intent.ACTION_VIEW);
smsMsgAppVar.setData(Uri.parse("sms:" +  mblNumVar));
smsMsgAppVar.putExtra("sms_body", "Hello Msg Tst Txt");
startActivity(smsMsgAppVar);

|Or| Use this function :

void openSmsMsgAppFnc(String mblNumVar, String smsMsgVar)
{
    Intent smsMsgAppVar = new Intent(Intent.ACTION_VIEW);
    smsMsgAppVar.setData(Uri.parse("sms:" +  mblNumVar));
    smsMsgAppVar.putExtra("sms_body", smsMsgVar);
    startActivity(smsMsgAppVar); 
}

Like this:

>>>mystr = "abcdefghijkl"
>>>mystr[-4:]
'ijkl'

This slices the string's last 4 characters. The -4 starts the range from the string's end. A modified expression with [:-4] removes the same 4 characters from the end of the string:

>>>mystr[:-4]
'abcdefgh'

For more information on slicing see this Stack Overflow answer.

If you want pure css, without the letter "x"....

Here are some awesome experimental icons that include an "x" in a circle that is made with CSS: http://nicolasgallagher.com/pure-css-gui-icons/demo/

Beside putting the script in through functions you can "just" include a link ( a link rel tag that is) in the header, the footer, in any template, where ever.

No. You should never just add a link to an external script like this in WordPress. Enqueuing them through the functions.php file ensures that scripts are loaded in the correct order.

Failure to enqueue them may result in your script not working, although it is written correctly.

XmlSerializer sr = new XmlSerializer(objectToSerialize.GetType());
TextWriter xmlWriter = new StreamWriter(filename);
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
sr.Serialize(xmlWriter, objectToSerialize, namespaces);

There are two options-

pip install cv2 

or

pip install opencv-python

Hope it helps.

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON

From what I've seen of this the following is true for Firefox and Chrome;

1) If you have a HTML page open from a remote host then file:// links will not work i.e. Your address bar reads http://someserver.domain and the page contains a link such as <a href="file:///S:/sharedfile.txt">

2) If you have a HTML page open from your local host then file:// links will work i.e. your address bar reads file:///C:/mydir/index.html and the page contains a link such as <a href="file:///S:/sharedfile.txt">

For Internet Explorer point 1) does not hold true. A file on your local host can be accessed using the file:// link syntax from a webpage on a remote host. This is considered a security flaw in IE^{(By who? References?)} (and it's there in IE8 too) because a remote host can access files on your local computer without your knowledge .... admittedly they have to get lucky with the filename but there are plenty of commonly named files there with the potential to contain personal/private information.

The problem for me was that I had .rnd in my home directory but it was owned by root. Deleting it and reissuing the openssl command fixed this.

SyntaxHighlighter is a fully functional self-contained code syntax highlighter developed in JavaScript. To get an idea of what SyntaxHighlighter is capable of, have a look at the demo page.

Add comments for two different columns of the EMPLOYEE table :

COMMENT ON EMPLOYEE
     (WORKDEPT IS 'see DEPARTMENT table for names',
     EDLEVEL IS 'highest grade level passed in school' )

A surprise I found out recently is that Bash natively supports tcp connections as file descriptors. To use:

exec 6<>/dev/tcp/ip.addr.of.server/445
echo -e "GET / HTTP/1.0\n" >&6
cat <&6

I'm using 6 as the file descriptor because 0,1,2 are stdin, stdout, and stderr. 5 is sometimes used by Bash for child processes, so 3,4,6,7,8, and 9 should be safe.

As per the comment below, to test for listening on a local server in a script:

exec 6<>/dev/tcp/127.0.0.1/445 || echo "No one is listening!"
exec 6>&- # close output connection
exec 6<&- # close input connection

To determine if someone is listening, attempt to connect by loopback. If it fails, then the port is closed or we aren't allowed access. Afterwards, close the connection.

Modify this for your use case, such as sending an email, exiting the script on failure, or starting the required service.

As I understand your question, You have one table with column as datatype decimal(18,9). And the column contains the data as follows:-

12.00
15.00
18.00
20.00

Now if you want to show record on UI without decimal value means like (12,15,18,20) then there are two options:-

1. Either cast this column as int in Select Clause
2. or may be you want to update this column value like (12,15,18,20).

To apply, First very simple just use the cast in select clause

select CAST(count AS INT) from tablename;

But if you want to update your column data with int value then you have to update you column datatype

and to do that

ALTER TABLE tablename ALTER COLUMN columnname decimal(9,0)

Then execute this

UPDATE tablename
   SET count = CAST(columnname AS INT)

You can try like below

DECLARE @sqlCommand NVARCHAR(4000)
DECLARE @ID INT
DECLARE @Name NVARCHAR(100)
SET @ID = 4
SET @sqlCommand = 'SELECT @Name = [Name]
FROM [AdventureWorks2014].[HumanResources].[Department]
WHERE DepartmentID = @ID'
EXEC sp_executesql @sqlCommand, N'@ID INT, @Name NVARCHAR(100) OUTPUT',
@ID = @ID, @Name = @Name OUTPUT
SELECT @Name ReturnedName

By default Confluence renders monospaced text with transparent background. You can edit global CSS to add grey color. From Confluence manual:

1. Choose the cog icon at top right of the screen, then choose Confluence Admin.
2. Choose Stylesheet.
3. Choose Edit.
4. Paste your custom CSS into the text field.
5. Choose Save.

Custom CSS for displaying grey background in monospaced blocks:

code {
    padding: 1px 5px 1px 5px; 
    font-family: Consolas, Menlo, Monaco, Lucida Console, Liberation Mono, DejaVu Sans Mono, Bitstream Vera Sans Mono, Courier New, monospace, serif;
    background-color: #eeeeee;
}

If you're using Confluence OnDemand (cloud):

1. Click the cog/gear in the bottom of the sidebar on the left
2. Select Look and Feel
3. Click the Sidebar, Header and Footer tab
4. Paste your custom CSS into the Header field
5. Wrap the code in a {style} block
6. Save

Paste the following:

{style}
code {
    padding: 1px 5px 1px 5px; 
    font-family: Consolas, Menlo, Monaco, Lucida Console, Liberation Mono, DejaVu Sans Mono, Bitstream Vera Sans Mono, Courier New, monospace, serif;
    background-color: #eeeeee;
}
{style}

After that you'll get nice and tidy stackoverflow-stylish inline code spans just by writing {{sometext}}.

With android support package revision 13( may 2013), there is DrawerLayout for creating a Navigation Drawer that can be pulled in from the edge of a window. And, navigation drawer is a design pattern now.

If you want to compare files visually you can use:

git difftool

It will start your diff app automatically for each changed file.

PS: If you did not set a diff app, you can do it like in the example below(I use Winmerge):

git config --global merge.tool winmerge
git config --replace --global mergetool.winmerge.cmd "\"C:\Program Files (x86)\WinMerge\WinMergeU.exe\" -e -u -dl \"Base\" -dr \"Mine\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\""
git config --global mergetool.prompt false

You might want to do something like this (if you're using java 5 and more)

Scanner scanner = new Scanner(new File("tall.txt"));
int [] tall = new int [100];
int i = 0;
while(scanner.hasNextInt())
{
     tall[i++] = scanner.nextInt();
}

If you just want to reset the select element to it's first position, the simplest way may be:

$('#name2').val('');

To reset all select elements in the document:

$('select').val('')

EDIT: To clarify as per a comment below, this resets the select element to its first blank entry and only if a blank entry exists in the list.

The way I do this is as follows:

@IBAction func pressButton(sender: AnyObject) {
    var disableMyButton = sender as? UIButton
    disableMyButton.enabled = false
}

The IBAction is connected to your button in the storyboard.

If you have your button setup as an Outlet:

    @IBOutlet weak var myButton: UIButton!

Then you can access the enabled properties by using the . notation on the button name:

    myButton.enabled = false

Run vim from the terminal. For the basics, you're advised to run the command vimtutor.

# On your terminal command line:
$ vim

If you have a specific file to edit, pass it as an argument.

$ vim yourfile.cpp

Likewise, launch the tutorial

$ vimtutor

For Windows, popen also works, but it opens up a console window - which quickly flashes over your UI application. If you want to be a professional, it's better to disable this "flashing" (especially if the end-user can cancel it).

So here is my own version for Windows:

(This code is partially recombined from ideas written in The Code Project and MSDN samples.)

#include <windows.h>
#include <atlstr.h>
//
// Execute a command and get the results. (Only standard output)
//
CStringA ExecCmd(
    const wchar_t* cmd              // [in] command to execute
)
{
    CStringA strResult;
    HANDLE hPipeRead, hPipeWrite;

    SECURITY_ATTRIBUTES saAttr = {sizeof(SECURITY_ATTRIBUTES)};
    saAttr.bInheritHandle = TRUE; // Pipe handles are inherited by child process.
    saAttr.lpSecurityDescriptor = NULL;

    // Create a pipe to get results from child's stdout.
    if (!CreatePipe(&hPipeRead, &hPipeWrite, &saAttr, 0))
        return strResult;

    STARTUPINFOW si = {sizeof(STARTUPINFOW)};
    si.dwFlags     = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
    si.hStdOutput  = hPipeWrite;
    si.hStdError   = hPipeWrite;
    si.wShowWindow = SW_HIDE; // Prevents cmd window from flashing.
                              // Requires STARTF_USESHOWWINDOW in dwFlags.

    PROCESS_INFORMATION pi = { 0 };

    BOOL fSuccess = CreateProcessW(NULL, (LPWSTR)cmd, NULL, NULL, TRUE, CREATE_NEW_CONSOLE, NULL, NULL, &si, &pi);
    if (! fSuccess)
    {
        CloseHandle(hPipeWrite);
        CloseHandle(hPipeRead);
        return strResult;
    }

    bool bProcessEnded = false;
    for (; !bProcessEnded ;)
    {
        // Give some timeslice (50 ms), so we won't waste 100% CPU.
        bProcessEnded = WaitForSingleObject( pi.hProcess, 50) == WAIT_OBJECT_0;

        // Even if process exited - we continue reading, if
        // there is some data available over pipe.
        for (;;)
        {
            char buf[1024];
            DWORD dwRead = 0;
            DWORD dwAvail = 0;

            if (!::PeekNamedPipe(hPipeRead, NULL, 0, NULL, &dwAvail, NULL))
                break;

            if (!dwAvail) // No data available, return
                break;

            if (!::ReadFile(hPipeRead, buf, min(sizeof(buf) - 1, dwAvail), &dwRead, NULL) || !dwRead)
                // Error, the child process might ended
                break;

            buf[dwRead] = 0;
            strResult += buf;
        }
    } //for

    CloseHandle(hPipeWrite);
    CloseHandle(hPipeRead);
    CloseHandle(pi.hProcess);
    CloseHandle(pi.hThread);
    return strResult;
} //ExecCmd

Another way would be to encode the quotes using htmlspecialchars:

$json_array = array(
    'title' => 'Example string\'s with "special" characters'
);

$json_decode = htmlspecialchars(json_encode($json_array), ENT_QUOTES, 'UTF-8');

In the OpenGL ES 2.0/3.0 you can also combining OGL View and Android's UI-elements:

public class GameActivity extends AppCompatActivity {
    private SurfaceView surfaceView;
    @Override
    protected void onCreate(Bundle state) { 
        setContentView(R.layout.activity_gl);
        surfaceView = findViewById(R.id.oglView);
        surfaceView.init(this.getApplicationContext());
        ...
    } 
}

public class SurfaceView extends GLSurfaceView {
    private SceneRenderer renderer;
    public SurfaceView(Context context) {
        super(context);
    }

    public SurfaceView(Context context, AttributeSet attributes) {
        super(context, attributes);
    }

    public void init(Context context) {
        renderer = new SceneRenderer(context);
        setRenderer(renderer);
        ...
    }
}

Create layout activity_gl.xml:

<?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.ConstraintLayout
        tools:context=".activities.GameActivity">
    <com.app.SurfaceView
        android:id="@+id/oglView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
    <TextView ... />
    <TextView ... />
    <TextView ... />
</androidx.constraintlayout.widget.ConstraintLayout>

To update elements from the render thread, can use Handler/Looper.

Here's a way to do it without using groups (Python 3.6 or above):

>>> re.search('2\d\d\d[01]\d[0-3]\d', 'report_20191207.xml')[0]
'20191207'

Check out the ruby-enum gem, https://github.com/dblock/ruby-enum.

  Gender.define :MALE, "male"
  Gender.define :FEMALE, "female"
end

Gender.all
Gender::MALE

Since you haven't made any commits yet, you can save all your changes to the stash, create and switch to a new branch, then pop those changes back into your working tree:

git stash  # save local modifications to new stash
git checkout -b topic/newbranch
git stash pop  # apply stash and remove it from the stash list

open C:\myfile.txt for append as #1
write #1, text1.text, text2.text
close()

This is the code I use in Visual Basic 6.0. It helps me to create a txt file on my drive, write two pieces of data into it, and then close the file... Give it a try...

You could also try this :

function replaceStr(str, find, replace) {
    for (var i = 0; i < find.length; i++) {
        str = str.replace(new RegExp(find[i], 'gi'), replace[i]);
    }
    return str;
}

var text = "#here_is_the_one#";
var find = ["#","_"];
var replace = ['',' '];
text = replaceStr(text, find, replace);
console.log(text);

find refers to the text to be found and replace to the text to be replaced with

This will be replacing case insensitive characters. To do otherway just change the Regex flags as required. Eg: for case sensitive replace :

new RegExp(find[i], 'g')

Generate the private key and server certificate with specific expiry date or with infinite(XXX) expiry time and self sign it.

$ openssl req -x509 -sha256 -newkey rsa:2048 -keyout key.pem -out cert.pem -days XXX

$ Enter a private key passphrase...`

Then it will work!

I tried the solution proposed above. But it was not cross-browser enough. I really needed ie11 to work. After trying I got to:

    <html>
        <body>
            <div id="a" onclick="copyDivToClipboard()"> Click to copy </div>
            <script>
                function copyDivToClipboard() {
                    var range = document.createRange();
                    range.selectNode(document.getElementById("a"));
                    window.getSelection().removeAllRanges(); // clear current selection
                    window.getSelection().addRange(range); // to select text
                    document.execCommand("copy");
                    window.getSelection().removeAllRanges();// to deselect
                }
            </script>
        </body>
    </html>

Tested with firefox 64, Chrome 71, Opera 57, ie11(11.472.17134.0), edge( EdgeHTML 17.17134)

Update March 27th, 2019.

For some reason document.createRange() didn't work before with ie11. But now properly returns a Range object. So is better to use that, rather than document.getSelection().getRangeAt(0).

use the below pattern to get content between element. Replace [tag] with the actual element you wish to extract the content from.

<[tag]>(.+?)</[tag]>

Sometime tags will have attributes, like anchor tag having href, then use the below pattern.

 <[tag][^>]*>(.+?)</[tag]>

According to the manual, in CPython id() is the actual memory address of the variable. If you want it in hex format, call hex() on it.

x = 5
print hex(id(x))

this will print the memory address of x.

My recipe to fix it:

1. DID NOT WORK >> Set as system environment variable: I had set the environment variable in my mac bash_profile, however, Tomcat did not see that variable.

2. DID NOT WORK >> setenv.sh: Apache's recommendation was to have user-defined environment variables in setenv.sh file and I did that.

3. THIS WORKED!! >> After a little research into Tomcat startup scripts, I found that environment variables set using setenv.sh are lost during the startup. So I had to edit my catalina.sh against the recommendation of Apache and that did the trick.

Add your -DUSER_DEFINED variable in the run command in catalina.sh.

eval exec "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
  -classpath "\"$CLASSPATH\"" \
  -Djava.security.manager \
  -Djava.security.policy=="\"$CATALINA_BASE/conf/catalina.policy\"" \
  -Dcatalina.base="\"$CATALINA_BASE\"" \
  -Dcatalina.home="\"$CATALINA_HOME\"" \
  -Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
  -DUSER_DEFINED="$USER_DEFINED" \
  org.apache.catalina.startup.Bootstrap "$@" start

P.S: This problem could have been local to my computer. Others would have different problems. Adding my answer to this post just in case anyone is still facing issues with Tomcat not seeing the environment vars after trying out all recommended approaches.

The shortest way is: @RequestMapping({"", "/", "welcome"})

Although you can also do:

• @RequestMapping(value={"", "/", "welcome"})
• @RequestMapping(path={"", "/", "welcome"})

I was quite inspired by the last answer by mklement0 - I have few scripts/small programs I run at every reboot via /etc/crontab. I built on his answer and built a login script, which shows if my programs are still running. I execute this scripts.sh via .profile -file on every login, to get instant notification on each login.

cat scripts.sh 
#!/bin/bash

getscript() {
  pgrep -lf ".[ /]$1( |\$)"
}

script1=keepalive.sh
script2=logger_v3.py

# test if script 1 is running
if getscript "$script1" >/dev/null; then
  echo "$script1" is RUNNING
  else
    echo "$script1" is NOT running
fi

# test if script 2 is running:
if getscript "$script2" >/dev/null; then
  echo "$script2" is RUNNING
  else
    echo "$script2" is NOT running
fi

UPDATE mytable SET spares = CONCAT(spares, ',', '818') WHERE id = 1

On Windows Server 2008(r2) you can't assign an application pool identity to a folder through Properties->Security. You can do it through an admin command prompt using the following though:

icacls "c:\yourdirectory" /t /grant "IIS AppPool\DefaultAppPool":(R)

For any wanderer that comes across this in the future. If your application and database are on different machines and you are getting the above error especially when using TransactionScope, enable Network DTC access. Steps to do this are:

1. Add firewall rules to allow your machines to talk to each other.
2. Ensure the distributed transaction coordinator service is running
3. Enable network dtc access. Run dcomcnfg. Go to Component sevices > My Computer > Distributed Transaction Coordinator > Local DTC. Right click properties.
4. Enable network dtc access as shown.

Important: Do not edit/change the user account and password in the DTC Logon account field, leave it as is, you will end up re-installing windows if you do.

As explained in this thread on the cxf-user mailing list, rather than having the CXFServlet load its own spring context from user-webservice-servlet.xml, you can just load the whole lot into the root context. Rename your existing user-webservice-servlet.xml to some other name (e.g. user-webservice-beans.xml) then change your contextConfigLocation parameter to something like:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/applicationContext.xml
    /WEB-INF/user-webservice-beans.xml
  </param-value>
</context-param>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>user-webservice</servlet-name>
  <url-pattern>/UserService/*</url-pattern>
</servlet-mapping>

From Django docs:

The include tag should be considered as an implementation of "render this subtemplate and include the HTML", not as "parse this subtemplate and include its contents as if it were part of the parent". This means that there is no shared state between included templates -- each include is a completely independent rendering process.

So Django doesn't grab any blocks from your commondata.html and it doesn't know what to do with rendered html outside blocks.

For Java 7+ doc you can use this:

BufferedReader reader = Files.newBufferedReader(path, StandardCharsets.UTF_8);

Here are all Charsets doc

For example if your file is in CP1252, use this method

Charset.forName("windows-1252");

Here is other canonical names for Java encodings both for IO and NIO doc

If you do not know with exactly encoding you have got in a file, you may use some third-party libs like this tool from Google this which works fairly neat.

In an empty directory:

git init
git remote add [REMOTE_NAME] [GIT_URL]
git fetch REMOTE_NAME
git checkout REMOTE_NAME/BRANCH -- path/to/directory

If your task is performing some kind of action in a loop there is a way to pause/restart processing, but I think it would have to be outside what the Thread API currently offers. If its a single shot process I am not aware of any way to suspend/restart without running into API that has been deprecated or is no longer allowed.

As for looped processes, the easiest way I could think of is that the code that spawns the Task instantiates a ReentrantLock and passes it to the task, as well as keeping a reference itself. Every time the Task enters its loop it attempts a lock on the ReentrantLock instance and when the loop completes it should unlock. You may want to encapsulate all this try/finally, making sure you let go of the lock at the end of the loop, even if an exception is thrown.

If you want to pause the task simply attempt a lock from the main code (since you kept a reference handy). What this will do is wait for the loop to complete and not let it start another iteration (since the main thread is holding a lock). To restart the thread simply unlock from the main code, this will allow the task to resume its loops.

To permanently stop the thread I would use the normal API or leave a flag in the Task and a setter for the flag (something like stopImmediately). When the loop encountered a true value for this flag it stops processing and completes the run method.

TxtFarmerSize.Text = (int)reader[3];

With mouseover only the element stays visible when mouse leaves the hovered element, so I added this:

@mouseover="active = !active" @mouseout="active = !active"

<script>
export default {
  data(){
   return {
     active: false
   }
 }
</script>

To get an image from a URL we can use the following code:

ImageIcon imgThisImg = new ImageIcon(PicURL));

jLabel2.setIcon(imgThisImg);

It totally works for me. The PicUrl is a string variable which strores the url of the picture.

A better usage is to create a scope in the user model where(arel_table[:id].gt(id))

if (code.indexOf("ST1")>=0) { location = "stoke central"; }

We can use on and off click for preventing Multiple clicks. i tried it to my application and it's working as expected.

$(document).ready(function () {     
    $("#disable").on('click', function () {
        $(this).off('click'); 
        // enter code here
    });
})

If you want to find dependencies recursively (including dependencies of dependencies, dependencies of dependencies of dependencies and so on)…

You may use ldd command. ldd - print shared library dependencies

jQuery Validation Unobtrusive Native is a collection of ASP.Net MVC HTML helper extensions. These make use of jQuery Validation's native support for validation driven by HTML 5 data attributes. Microsoft shipped jquery.validate.unobtrusive.js back with MVC 3. It provided a way to apply data model validations to the client side using a combination of jQuery Validation and HTML 5 data attributes (that's the "unobtrusive" part).

This is a revised version from @hounded. My code handles both date and time, something like 43705.591795706

    import math
    import datetime


    def xldate_to_datetime(xldatetime): #something like 43705.6158241088

      tempDate = datetime.datetime(1899, 12, 31)
      (days, portion) = math.modf(xldatetime)

      deltaDays = datetime.timedelta(days=days)
      #changing the variable name in the edit
      secs = int(24 * 60 * 60 * portion)
      detlaSeconds = datetime.timedelta(seconds=secs)
      TheTime = (tempDate + deltaDays + detlaSeconds )
      return TheTime.strftime("%Y-%m-%d %H:%M:%S")

The most easy way to do is copy innerHTML of that element to tmp variable and make it empty, then append new element, and after that copy back tmp variable to it. Here is an example I used to add jquery script to top of head.

var imported = document.createElement('script');
imported.src = 'http://code.jquery.com/jquery-1.7.1.js';
var tmpHead = document.head.innerHTML;
document.head.innerHTML = "";
document.head.append(imported);
document.head.innerHTML += tmpHead;

That simple :)

With define keyword constant, you will get the facilities of case insensitive but with const keyword you did not.

define("FOO", 1, true);
echo foo; //1
echo "<br/>";
echo FOO; //1
echo "<br/>";

class A {
  const FOO = 1;
}

echo A::FOO; //valid
echo "<br/>";

//but

class B {
  define FOO = 1; //syntax error, unexpected 'define'
}

echo B::FOO; //invalid

If you don't want to install MySQL workbench, and are looking for an online tool, this might help: http://ondras.zarovi.cz/sql/demo/

I use it quite often to create simple DB schemas for various apps I build.

you can use

^[\w.-]+$

the + is to make sure it has at least 1 character. Need the ^ and $ to denote the begin and end, otherwise if the string has a match in the middle, such as @@@@xyz%%%% then it is still a match.

\w already includes alphabets (upper and lower case), numbers, and underscore. So the rest ., -, are just put into the "class" to match. The + means 1 occurrence or more.

P.S. thanks for the note in the comment

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?

You could check in the following way (extra = and making length a truthy evaluation)

if (typeof(sub.from) !== 'undefined' && sub.from.length) {

[update]

I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:

for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
            mainid = sub.from[i]['id'];
            var sub = afcHelper_Submissions[mainid]; // <== re setting sub

My guess is that the error is not on the if statement but on the for(i... statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

If it's just a substring search you can use string.find("substring").

You do have to be a little careful with find, index, and in though, as they are substring searches. In other words, this:

s = "This be a string"
if s.find("is") == -1:
    print("No 'is' here!")
else:
    print("Found 'is' in the string.")

It would print Found 'is' in the string. Similarly, if "is" in s: would evaluate to True. This may or may not be what you want.

The app project you downloaded may include a signed info in the file of build.gradle. If you saw codes like these:

buildTypes {
    debug {
        signingConfig signingConfigs.release
    }
    release {
        signingConfig signingConfigs.release
    }
}

you could delete them and try again.

You can do it by using pymysql:

For example, let's suppose you have a MySQL database with the next user, password, host and port and you want to write in the database 'data_2', if it is already there or not.

import pymysql
user = 'root'
passw = 'my-secret-pw-for-mysql-12ud'
host =  '172.17.0.2'
port = 3306
database = 'data_2'

If you already have the database created:

conn = pymysql.connect(host=host,
                       port=port,
                       user=user, 
                       passwd=passw,  
                       db=database,
                       charset='utf8')

data.to_sql(name=database, con=conn, if_exists = 'replace', index=False, flavor = 'mysql')

If you do NOT have the database created, also valid when the database is already there:

conn = pymysql.connect(host=host, port=port, user=user, passwd=passw)

conn.cursor().execute("CREATE DATABASE IF NOT EXISTS {0} ".format(database))
conn = pymysql.connect(host=host,
                       port=port,
                       user=user, 
                       passwd=passw,  
                       db=database,
                       charset='utf8')

data.to_sql(name=database, con=conn, if_exists = 'replace', index=False, flavor = 'mysql')

Similar threads:

1. Writing to MySQL database with pandas using SQLAlchemy, to_sql
2. Writing a Pandas Dataframe to MySQL

From APUE, Section 5.14 :

char    good_template[] = "/tmp/dirXXXXXX"; /* right way */
char    *bad_template = "/tmp/dirXXXXXX";   /* wrong way*/

... For the first template, the name is allocated on the stack, because we use an array variable. For the second name, however, we use a pointer. In this case, only the memory for the pointer itself resides on the stack; the compiler arranges for the string to be stored in the read-only segment of the executable. When the mkstemp function tries to modify the string, a segmentation fault occurs.

The quoted text matches @Ciro Santilli 's explanation.

The newest version has some nice in-line stuff you can do.

If it's a simple input field you can add the attribute data-validation-error-msg like this --

data-validation-error-msg="Invalid Regex"

If you need something a little heavier you can fully customize things using a variable with all the values which is passed into the validate function. Reference this link for full details -- https://github.com/victorjonsson/jQuery-Form-Validator#fully-customizable

I could not make @Clockwork-Muse work actually. But I could make this variation work:

WITH Tmp AS (SELECT * FROM (VALUES (id1, newsPosX1, newPosY1), 
                                   (id2, newsPosX2, newPosY2),
                                   ......................... ,
                                   (idN, newsPosXN, newPosYN)) d(id, px, py))

UPDATE t

SET posX = (SELECT px FROM Tmp WHERE t.id = Tmp.id),
    posY = (SELECT py FROM Tmp WHERE t.id = Tmp.id)

FROM TableToUpdate t

I hope this works for you too!

Swift 3.X+ , Xcode 8.X + Tested working easy solution;

Use simple ;

let myString = "12.12.2017 12:34:45"
let newString = myString?[(myString?.startIndex)!..<(myString?.index((myString?.startIndex)!, offsetBy: 10))!]
print(newString) 

Output = 12.12.2017

For customization easily change;

offsetBy: 10 // Change 10 to endIndex.

When you change offsetBy: 10 to 15,20 etc. Will cut your string..

Thank you !

I have a project using static table view cells, in iOS 7.x. willDisplayHeaderView does not fire. However, this method works ok:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    NSLog(@"%s", __FUNCTION__);
    CGRect headerFrame = CGRectMake(x, y, w, h);    
    UIView *headerView = [[UIView alloc] initWithFrame:headerFrame];  
    headerView.backgroundColor = [UIColor blackColor];

Use

day1 = (int)ClockInfoFromSystem.DayOfWeek;

Time. .Now includes the 09:23:12 or whatever; .Today is the date-part only (at 00:00:00 on that day).

So use .Now if you want to include the time, and .Today if you just want the date!

.Today is essentially the same as .Now.Date

try this for close app

Activity.finish();
System.exit(0);

The HTTP 502 "Bad Gateway" response is generated when Apache web server does not receive a valid HTTP response from the upstream server, which in this case is your Tomcat web application.

Some reasons why this might happen:

• Tomcat may have crashed
• The web application did not respond in time and the request from Apache timed out
• The Tomcat threads are timing out
• A network device is blocking the request, perhaps as some sort of connection timeout or DoS attack prevention system

If the problem is related to timeout settings, you may be able to resolve it by investigating the following:

• ProxyTimeout directive of Apache's mod_proxy
• Connector config of Apache Tomcat
• Your network device's manual

Change the database.php file from

Omkar's answer is quite comprehensive.

But some part of the Global config part has changed.

According to the spring boot 2.0.2.RELEASE reference

As of version 4.2, Spring MVC supports CORS. Using controller method CORS configuration with @CrossOrigin annotations in your Spring Boot application does not require any specific configuration. Global CORS configuration can be defined by registering a WebMvcConfigurer bean with a customized addCorsMappings(CorsRegistry) method, as shown in the following example:

@Configuration
public class MyConfiguration {

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/api/**");
            }
        };
    }
}

Most answer in this post using WebMvcConfigurerAdapter, however

The type WebMvcConfigurerAdapter is deprecated

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class

let's do try and checkout For Swift 3...

UIView.transition(with: mysuperview, duration: 0.75, options:UIViewAnimationOptions.transitionFlipFromRight , animations: {
    myview.removeFromSuperview()
}, completion: nil)

Just a tip: Remember to put the code detection on document.ready, otherwise it might not work. That was my case.

A much simpler solution would be to download the file using Chrome. In this manner you don't have to manually click on the save button.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
    class MyProcess
    {
        public static void Main()
        {
            Process myProcess = new Process();
            myProcess.Start("chrome.exe","http://www.com/newfile.zip");
        }
    }
}

 private List<String> FindString(String stringToLookFor, List<String> arrayToSearchIn)
 {
     List<String> ReceptacleOfWordsFound = new ArrayList<String>();

     if(!arrayToSearchIn.isEmpty())
     {
         for(String lCurrentString : arrayToSearchIn)
         {
             if(lCurrentString.toUpperCase().contains(stringToLookFor.toUpperCase())
                 ReceptacleOfWordsFound.add(lCurrentString);
         }
     }
  return ReceptacleOfWordsFound;
 }

In one line:

String date=new SimpleDateFormat("MM-dd-yyyy").format(new SimpleDateFormat("yyyy-MM-dd").parse("2011-01-01"));

Where:

String date=new SimpleDateFormat("FinalFormat").format(new SimpleDateFormat("InitialFormat").parse("StringDate"));

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

Result:

Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

You need antMatcher for multiple HttpSecurity, see Spring Security Reference:

5.7 Multiple HttpSecurity

We can configure multiple HttpSecurity instances just as we can have multiple <http> blocks. The key is to extend the WebSecurityConfigurationAdapter multiple times. For example, the following is an example of having a different configuration for URL’s that start with /api/.

@EnableWebSecurity
public class MultiHttpSecurityConfig {
  @Autowired
  public void configureGlobal(AuthenticationManagerBuilder auth) { 1
      auth
          .inMemoryAuthentication()
              .withUser("user").password("password").roles("USER").and()
              .withUser("admin").password("password").roles("USER", "ADMIN");
  }

  @Configuration
  @Order(1)                                                        2
  public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
      protected void configure(HttpSecurity http) throws Exception {
          http
              .antMatcher("/api/**")                               3
              .authorizeRequests()
                  .anyRequest().hasRole("ADMIN")
                  .and()
              .httpBasic();
      }
  }    

  @Configuration                                                   4
  public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

      @Override
      protected void configure(HttpSecurity http) throws Exception {
          http
              .authorizeRequests()
                  .anyRequest().authenticated()
                  .and()
              .formLogin();
      }
  }
}

1 Configure Authentication as normal

2 Create an instance of WebSecurityConfigurerAdapter that contains @Order to specify which WebSecurityConfigurerAdapter should be considered first.

3 The http.antMatcher states that this HttpSecurity will only be applicable to URLs that start with /api/

4 Create another instance of WebSecurityConfigurerAdapter. If the URL does not start with /api/ this configuration will be used. This configuration is considered after ApiWebSecurityConfigurationAdapter since it has an @Order value after 1 (no @Order defaults to last).

In your case you need no antMatcher, because you have only one configuration. Your modified code:

http
    .authorizeRequests()
        .antMatchers("/high_level_url_A/sub_level_1").hasRole('USER')
        .antMatchers("/high_level_url_A/sub_level_2").hasRole('USER2')

First a helper function adapted from the itertools pairwise recipe to produce substrings.

import itertools
def n_wise(iterable, n = 2):
    '''n = 2 -> (s0,s1), (s1,s2), (s2, s3), ...

    n = 3 -> (s0,s1, s2), (s1,s2, s3), (s2, s3, s4), ...'''
    a = itertools.tee(iterable, n)
    for x, thing in enumerate(a[1:]):
        for _ in range(x+1):
            next(thing, None)
    return zip(*a)

Then a function the iterates over substrings, longest first, and tests for membership. (efficiency not considered)

def foo(s1, s2):
    '''Finds the longest matching substring
    '''
    # the longest matching substring can only be as long as the shortest string
    #which string is shortest?
    shortest, longest = sorted([s1, s2], key = len)
    #iterate over substrings, longest substrings first
    for n in range(len(shortest)+1, 2, -1):
        for sub in n_wise(shortest, n):
            sub = ''.join(sub)
            if sub in longest:
                #return the first one found, it should be the longest
                return sub

s = "fdomainster"
t = "exdomainid"
print(foo(s,t))

>>> 
domain

This extension helps you to constraint a UIVIew to its superview and superview+safeArea:

extension UIView {

    ///Constraints a view to its superview
    func constraintToSuperView() {
        guard let superview = superview else { return }
        translatesAutoresizingMaskIntoConstraints = false

        topAnchor.constraint(equalTo: superview.topAnchor).isActive = true
        leftAnchor.constraint(equalTo: superview.leftAnchor).isActive = true
        bottomAnchor.constraint(equalTo: superview.bottomAnchor).isActive = true
        rightAnchor.constraint(equalTo: superview.rightAnchor).isActive = true
    }

    ///Constraints a view to its superview safe area
    func constraintToSafeArea() {
        guard let superview = superview else { return }
        translatesAutoresizingMaskIntoConstraints = false

        topAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.topAnchor).isActive = true
        leftAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.leftAnchor).isActive = true
        bottomAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.bottomAnchor).isActive = true
        rightAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.rightAnchor).isActive = true
    }

}

compatible with chrome, firefox, opera, Internet Explorer
Note: jQuery required.

<script>

    window.onafterprint = function(e){
        $(window).off('mousemove', window.onafterprint);
        console.log('Print Dialog Closed..');
    };

    window.print();

    setTimeout(function(){
        $(window).one('mousemove', window.onafterprint);
    }, 1);

Alternative and much easier way is to use shapes instead of 9-patches. It is already explained here: https://stackoverflow.com/a/24725831/512011

I use the following function to post data using curl. $data is an array of fields to post (will be correctly encoded using http_build_query). The data is encoded using application/x-www-form-urlencoded.

function httpPost($url, $data)
{
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($curl);
    curl_close($curl);
    return $response;
}

@Edward mentions that http_build_query may be omitted since curl will correctly encode array passed to CURLOPT_POSTFIELDS parameter, but be advised that in this case the data will be encoded using multipart/form-data.

I use this function with APIs that expect data to be encoded using application/x-www-form-urlencoded. That's why I use http_build_query().

Test for ':' first, then take test string up to ':' or end, depending on if it was found

Dim strResult As String

' Position of :
intPos = InStr(1, strTest, ":")
If intPos > 0 Then
    ' : found, so take up to :
    strResult = Left(strTest, intPos - 1)
Else
    ' : not found, so take whole string
    strResult = strTest
End If

In bash (>=4.2) it is preferable to use printf's built-in date formatter (part of bash) rather than the external date (usually GNU date).

As such:

# put current date as yyyy-mm-dd in $date
# -1 -> explicit current date, bash >=4.3 defaults to current time if not provided
# -2 -> start time for shell
printf -v date '%(%Y-%m-%d)T\n' -1 

# put current date as yyyy-mm-dd HH:MM:SS in $date
printf -v date '%(%Y-%m-%d %H:%M:%S)T\n' -1 

# to print directly remove -v flag, as such:
printf '%(%Y-%m-%d)T\n' -1
# -> current date printed to terminal

In bash (<4.2):

# put current date as yyyy-mm-dd in $date
date=$(date '+%Y-%m-%d')

# put current date as yyyy-mm-dd HH:MM:SS in $date
date=$(date '+%Y-%m-%d %H:%M:%S')

# print current date directly
echo $(date '+%Y-%m-%d')

Other available date formats can be viewed from the date man pages (for external non-bash specific command):

man date

If you are extending from an AppCompatActivity and are trying to get the ActionBar from the Fragment, you can do this:

ActionBar mActionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();

By the way guys, (int)Decimal.MaxValue will overflow. You can't get the "int" part of a decimal because the decimal is too friggen big to put in the int box. Just checked... its even too big for a long (Int64).

If you want the bit of a Decimal value to the LEFT of the dot, you need to do this:

Math.Truncate(number)

and return the value as... A DECIMAL or a DOUBLE.

edit: Truncate is definitely the correct function!

For Visual Studio Code:

• Open launch.json file
• Add args to your configuration:

"args": ["some argument", "another one"],

In my case my request object inherited from base object. Without knowingly I added a property with int? in my request object and my base object also has same property ( same name ) with int datatype. I noticed this and deleted the property which I added in request object and after that it worked fine.

The columns parameter accepts a collection of column names. You're passing a list containing a dataframe with two rows:

>>> [df[1:]]
[  viz  a1_count  a1_mean  a1_std
1   n         0      NaN     NaN
2   n         2       51      50]
>>> df.as_matrix(columns=[df[1:]])
array([[ nan,  nan],
       [ nan,  nan],
       [ nan,  nan]])

Instead, pass the column names you want:

>>> df.columns[1:]
Index(['a1_count', 'a1_mean', 'a1_std'], dtype='object')
>>> df.as_matrix(columns=df.columns[1:])
array([[  3.      ,   2.      ,   0.816497],
       [  0.      ,        nan,        nan],
       [  2.      ,  51.      ,  50.      ]])

There are quite a few working answers here, but I found this the easiest. This command will open up an editor, where you can just replace pick with squash in order to remove/merge them into one

git rebase -i HEAD~4

where, 4 is the number of commits you want to squash into one. This is explained here as well.

Extract (refactor) your statements. And use the magic of and and or to decide when to short-circuit.

def a():
    try: # a code
    except: pass # or raise
    else: return True

def b():
    try: # b code
    except: pass # or raise
    else: return True

def c():
    try: # c code
    except: pass # or raise
    else: return True

def d():
    try: # d code
    except: pass # or raise
    else: return True

def main():   
    try:
        a() and b() or c() or d()
    except:
        pass

The package it-self is located under /data/app/com.company.appname-xxx.apk.

/data/app/com.company.appname is only a directory created to store files like native libs, cache, ecc...

You can retrieve the package installation path with the Context.getPackageCodePath() function call.

To get screen resolution in JS use screen object

screen.height;
screen.width;

Based on that values you can calculate your margin to whatever suits you.

The other answers here presuppose that you have a regex engine which supports non-greedy matching, which is an extension introduced in Perl 5 and widely copied to other modern languages; but it is by no means ubiquitous.

Many older or more conservative languages and editors only support traditional regular expressions, which have no mechanism for controlling greediness of the repetition operator * - it always matches the longest possible string.

The trick then is to limit what it's allowed to match in the first place. Instead of .* you seem to be looking for

[^>]*

which still matches as many of something as possible; but the something is not just . "any character", but instead "any character which isn't >".

Depending on your application, you may or may not want to enable an option to permit "any character" to include newlines.

Even if your regular expression engine supports non-greedy matching, it's better to spell out what you actually mean. If this is what you mean, you should probably say this, instead of rely on non-greedy matching to (hopefully, probably) Do What I Mean.

For example, a regular expression with a trailing context after the wildcard like .*?><br/> will jump over any nested > until it finds the trailing context (here, ><br/>) even if that requires straddling multiple > instances and newlines if you let it, where [^>]*><br/> (or even [^\n>]*><br/> if you have to explicitly disallow newline) obviously can't and won't do that.

Of course, this is still not what you want if you need to cope with <img title="quoted string with > in it" src="other attributes"> and perhaps <img title="nested tags">, but at that point, you should finally give up on using regular expressions for this like we all told you in the first place.

you are calling the context of not existing activity...so just replace your code in onClick(View v) as Intent intent=new Intent(this,Katra_home.class); startActivity(intent); it will definitely works....

If you need to do it with a set number of columns, H.B.'s way is best. But if you don't know how many columns you are dealing with until runtime, then the below code [read: hack] will work. I am not sure if there is a better solution with an unknown number of columns. It took me two days working at it off and on to get it, so I'm sticking with it regardless.

C#

public class ValueToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        int input;
        try
        {
            DataGridCell dgc = (DataGridCell)value;
            System.Data.DataRowView rowView = (System.Data.DataRowView)dgc.DataContext;
            input = (int)rowView.Row.ItemArray[dgc.Column.DisplayIndex];
        }
        catch (InvalidCastException e)
        {
            return DependencyProperty.UnsetValue;
        }
        switch (input)
        {
            case 1: return Brushes.Red;
            case 2: return Brushes.White;
            case 3: return Brushes.Blue;
            default: return DependencyProperty.UnsetValue;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}

A complementary note about CREATE TABLE .. TYPE="" syntax in SQL dump files

TLDR: If you still get CREATE TABLE ... TYPE="..." statements in SQL dump files generated by third party tools, it most certainly indicates that your server is configured to use a default sqlmode of MYSQL40 or MYSQL323.

Long story

As it was said by others, the TYPE argument to CREATE TABLE has been deprecated for a long time in MySQL. mysqldump correctly uses the ENGINE argument, unless you specifically ask it to generate a backward compatible dump (for example using --compatible=mysql40 in versions of mysqldump up to 5.7).

However, many external SQL dump tools (for example, those integrated in MySQL clients such as phpmyadmin, Navicat and DBVisualizer, as well as those used by external automated backup services such as iControlWP) are not specifically aware of this change, and instead rely on the SHOW CREATE TABLE ... command to provide table creation statements for each tables (and just to it make it clear: this is actually a good thing). However, the SHOW CREATE TABLE will actually produce outdated syntax, including the TYPE argument, if the sqlmode variable is set to MYSQL40 or MYSQL323.

Therefore, if you still get CREATE TABLE ... TYPE="..." statements in SQL dump files generated by third party tools, it most certainly indicates that your server is configured to use a default sqlmode of MYSQL40 or MYSQL323.

These sqlmodes basically configure MySQL to retain some backward compatible behaviours, and using them by default was largely recommended a few years ago. It is however highly improbable that you still have any code that wouldn't work correctly without these modes. Anyway, MYSQL40, MYSQL323 and several other similar sqlmodes have themselves been deprecated and are not supported in MySQL 8.0 and higher.

If your server is still configured with these sqlmodes and you are worried that some legacy program might fail if you change these, then one possibility is to set the sqlmode locally for that program, by executing SET SESSION sql_mode = 'MYSQL40'; immediately after connection. Note that this should only be considered as a temporary patch, and will not work in MySQL 8.0 and higher.

A more future-proof solution that do not involve rewriting your SQL queries would be to determine exactly which compatibility features need to be enable, and to enable only those, on a per-program basis (as described previously). The default sqlmode (that is, in server's configuration) should ideally be left unset (which will use official MySQL defaults for your current version). The full list of sqlmode (as of MySQL 5.7) is described here: https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html.
