I've used it to construct objects allocated on the stack via alloca().

shameless plug: I blogged about it here.

The awk variant :

awk '1;/CLIENTSCRIPT=/{print "CLIENTSCRIPT2=\"hello\""}' file

The below code will help you to auto open the .exe file from excel...

Sub Auto_Open()


    Dim x As Variant
    Dim Path As String

    ' Set the Path variable equal to the path of your program's installation
    Path = "C:\Program Files\GameTop.com\Alien Shooter\game.exe"
    x = Shell(Path, vbNormalFocus)

End Sub

This worked for me on Ubuntu 16.04:

python2 -m pip install ipykernel
python2 -m ipykernel install --user

python3 -m pip install ipykernel
python3 -m ipykernel install --user

Reference to the documentation:
Kernels for Python 2 and 3. Installing the IPython kernel - IPython Docs.

<select name="foo" id="foo">
 <option value="1">a</option>
 <option value="2">b</option>
 <option value="3">c</option>
  </select>
  <input type="button" id="button" value="Button" />
  });
  <script> ("#foo").val() </script>

which returns 1 if you have selected a and so on..

std::fill(v.begin(), v.end(), 0);

The answer is simple. Just divide string by 1. Examples:

"2" > "10"   - true

but

"2"/1 > "10"/1 - false

Also you can check if string value really is number:

!isNaN("1"/1) - true (number)
!isNaN("1a"/1) - false (string)
!isNaN("01"/1) - true (number)
!isNaN(" 1"/1) - true (number)
!isNaN(" 1abc"/1) - false (string)

But

!isNaN(""/1) - true (but string)

Solution

number !== "" && !isNaN(number/1)

You could use this code:

public class MyTask implements Runnable {

    private CountDownLatch countDownLatch;

    public MyTask(CountDownLatch countDownLatch {
         this.countDownLatch = countDownLatch;
    }

    @Override
    public void run() {
         try {
             //Do somethings
             //
             this.countDownLatch.countDown();//important
         } catch (InterruptedException ex) {
              Thread.currentThread().interrupt();
         }
     }
}

CountDownLatch countDownLatch = new CountDownLatch(NUMBER_OF_TASKS);
ExecutorService taskExecutor = Executors.newFixedThreadPool(4);
for (int i = 0; i < NUMBER_OF_TASKS; i++){
     taskExecutor.execute(new MyTask(countDownLatch));
}
countDownLatch.await();
System.out.println("Finish tasks");

• Upcasting is an operation that creates a base class reference from a subclass reference. (subclass -> superclass) (i.e. Manager -> Employee)
• Downcasting is an operation that creates a subclass reference from a base class reference. (superclass -> subclass) (i.e. Employee -> Manager)

In your case

Employee emp = (Employee)mgr; //mgr is Manager

you are doing an upcasting.

An upcast always succeeds unlike a downcast that requires an explicit cast because it can potentially fail at runtime.(InvalidCastException).

C# offers two operators to avoid this exception to be thrown:

Starting from:

Employee e = new Employee();

First:

Manager m = e as Manager; // if downcast fails m is null; no exception thrown

Second:

if (e is Manager){...} // the predicate is false if the downcast is not possible 

Warning: When you do an upcast you can only access to the superclass' methods, properties etc...

Lessons to learn from this:

1) Guid is a value type, not a reference type.

2) Calling the default constructor new S() on any value type always gives you back the all-zero form of that value type, whatever it is. It is logically the same as default(S).

I just had the same problem after accepting a Java update--scores of build errors and android import not recognized. On checking the build path in Project=>Properties, I found that the check box for Android 4.3 had somehow gotten cleared. Checking it resolved all the import errors without my even having to restart the IDE or run a project clean.

It seems that the original test case is wrong.

I can confirm that the selector #my_parent_element * works with unbind().

Let's take the following html as an example:

<div id="#my_parent_element">
  <div class="div1">
    <div class="div2">hello</div>
    <div class="div3">my</div>
  </div>
  <div class="div4">name</div>
  <div class="div5">
    <div class="div6">is</div>
    <div class="div7">
      <div class="div8">marco</div>
      <div class="div9">(try and click on any word)!</div>
    </div>
  </div>
</div>
<button class="unbind">Now, click me and try again</button>

And the jquery bit:

$('.div1,.div2,.div3,.div4,.div5,.div6,.div7,.div8,.div9').click(function() {
  alert('hi!');
})
$('button.unbind').click(function() {
  $('#my_parent_element *').unbind('click');
})

You can try it here: http://jsfiddle.net/fLvwbazk/7/

You could also use a pseudo class selector in your CSS like this:

.desc:not(:first-child) {
    display: none;
}

That will not apply the class to the first element with the class .desc.

Here's a JSFiddle with an example: http://jsfiddle.net/YYTFT/, and this is a good source to explain pseudo class selectors: http://css-tricks.com/pseudo-class-selectors/

Works for me on a mysql database also:

Entity\Entity_name:
    type: entity
    table: table_name
    fields: 
        field_name:
            type: integer
            nullable: true
            options:
                default: 1

You can go through all the answers above to understand why the .add() is restricted to '<?>', '<? extends>', and partly to '<? super>'.

But here's the conclusion of it all if you want to remember it, and dont want to go exploring the answer every time:

List<? extends A> means this will accept any List of A and subclass of A. But you cannot add anything to this list. Not even objects of type A.

List<? super A> means this will accept any list of A and superclass of A. You can add objects of type A and its subclasses.

This one worked for me.

window.open("data:application/octet-stream;charset=utf-16le;base64,"+data64);

This one worked too

 let a = document.createElement("a");
 a.href = "data:application/octet-stream;base64,"+data64;
 a.download = "documentName.pdf"
 a.click();

Please try this

(function ($) {
    $(document).ready(function(){
       function validateEmail(email) {
            const re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
            return re.test(email);
           }
       
       if($('.submitclass').length){
            $('.submitclass').click(function(){
                $email_id = $('.custom-email-field').val();
                if (validateEmail($email_id)) {
                  var url= $(this).attr('pdf_url');
                  var link = document.createElement('a');
                  link.href = url;
                  link.download = url.split("/").pop();
                  link.dispatchEvent(new MouseEvent('click'));
                }
            });
       }
    });
}(jQuery));

This article can help you Configuring PHP with MySQL for Apache 2 or IIS in Windows. Look at the section "Configure PHP and MySQL under Apache 2", point 3:

extension_dir = "c:\php\extensions"      ; FOR PHP 4 ONLY 
extension_dir = "c:\php\ext"             ; FOR PHP 5 ONLY

You must uncomment extension_dir param line and set it to absolute path to the PHP extensions directory.

"Best" helpdesk system is very subjective, of course, but I recommend Request Tracker (aka RT).

It has a default workflow built in, but is easily configured for alternate workflows using the "Scrips" and templates. Very extensible if you want.

var custApp = angular.module("custApp", [])
.controller('FirstController', FirstController)
.controller('SecondController',SecondController)
.service('sharedData', SharedData);

FirstController.$inject = ['sharedData'];
function FirstController(sharedData) {
this.data = sharedData.data;
}

SecondController.$inject['sharedData'];
function SecondController(sharedData) {
this.data = sharedData.data;
}

function SharedData() {
this.data = {
    value: 'default Value'
}
}

First Controller

<div ng-controller="FirstController as vm">
<input type=text ng-model="vm.data.value" />
</div>

Second Controller

 <div ng-controller="SecondController as vm">
    Second Controller<br>
    {{vm.data.value}}
</div>

you can simply cast a string array to int array by:

var converted = arr.Select(int.Parse)

If it helps anyone, and this may be laughable, but not obvious to me, was the application pool was not started. I just presumed on starting the website or creating the application pool, it would start. In fact, I didn't even know you had to start the application pool...

I landed here on my search for regex to convert this print syntax between print "string", in Python2 in old scripts with: print("string"), for Python3. Works well, otherwise use 2to3.py for additional conversions. Here is my solution for others:

Try it out on Regexr.com (doesn't work in NP++ for some reason):

find:     (?<=print)( ')(.*)(')
replace: ('$2')

for variables:

(?<=print)( )(.*)(\n)
('$2')\n

for label and variable:

(?<=print)( ')(.*)(',)(.*)(\n)
('$2',$4)\n

How to replace all print "string" in Python2 with print("string") for Python3?

I started to go this route, but I have my own navigation control with a core view that I slide into a frame that's usually wrapping the core with a common title bar and tabbar; no storyboard, no UINavigationController.

It started to get complicated fast, adding and subtracting the 20 pixels of the status bar. Then an epiphany.

I made a copy of the .xib file, told Xcode to show it to me as an iOS 7 layout, realigned everything, and put a single 6/7 switch in code .. instantly, everything works right, and the additional resources add only 8K to the bundle.

you can intersect types:

type TypeA = {
    nameA: string;
};
type TypeB = {
    nameB: string;
};
export type TypeC = TypeA & TypeB;

somewhere in you code you can now do:

const some: TypeC = {
    nameB: 'B',
    nameA: 'A',
};

use CURL luke :) seriously, thats one of the best ways to do it AND you get the response.

what are Access Specifiers?

There are 3 access specifiers for a class/struct/Union in C++. These access specifiers define how the members of the class can be accessed. Of course, any member of a class is accessible within that class(Inside any member function of that same class). Moving ahead to type of access specifiers, they are:

Public - The members declared as Public are accessible from outside the Class through an object of the class.

Protected - The members declared as Protected are accessible from outside the class BUT only in a class derived from it.

Private - These members are only accessible from within the class. No outside Access is allowed.

An Source Code Example:

class MyClass
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

int main()
{
    MyClass obj;
    obj.a = 10;     //Allowed
    obj.b = 20;     //Not Allowed, gives compiler error
    obj.c = 30;     //Not Allowed, gives compiler error
}

Inheritance and Access Specifiers

Inheritance in C++ can be one of the following types:

• Private Inheritance
• Public Inheritance
• Protected inheritance

Here are the member access rules with respect to each of these:

First and most important rule Private members of a class are never accessible from anywhere except the members of the same class.

Public Inheritance:

All Public members of the Base Class become Public Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

i.e. No change in the Access of the members. The access rules we discussed before are further then applied to these members.

Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:public Base
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Allowed
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Private Inheritance:

All Public members of the Base Class become Private Members of the Derived class &
All Protected members of the Base Class become Private Members of the Derived Class.

An code Example:

Class Base
{
    public:
      int a;
    protected:
      int b;
    private:
      int c;
};

class Derived:private Base   //Not mentioning private is OK because for classes it  defaults to private 
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Not Allowed, Compiler Error, a is private member of Derived now
        b = 20;  //Not Allowed, Compiler Error, b is private member of Derived now
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Protected Inheritance:

All Public members of the Base Class become Protected Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

A Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:protected Base  
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Allowed, a is protected member inside Derived & Derived2 is public derivation from Derived, a is now protected member of Derived2
        b = 20;  //Allowed, b is protected member inside Derived & Derived2 is public derivation from Derived, b is now protected member of Derived2
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error
}

Remember the same access rules apply to the classes and members down the inheritance hierarchy.

Important points to note:

- Access Specification is per-Class not per-Object

Note that the access specification C++ work on per-Class basis and not per-object basis.
A good example of this is that in a copy constructor or Copy Assignment operator function, all the members of the object being passed can be accessed.

- A Derived class can only access members of its own Base class

Consider the following code example:

class Myclass
{ 
    protected: 
       int x; 
}; 

class derived : public Myclass
{
    public: 
        void f( Myclass& obj ) 
        { 
            obj.x = 5; 
        } 
};

int main()
{
    return 0;
}

It gives an compilation error:

prog.cpp:4: error: ‘int Myclass::x’ is protected

Because the derived class can only access members of its own Base Class. Note that the object obj being passed here is no way related to the derived class function in which it is being accessed, it is an altogether different object and hence derived member function cannot access its members.

What is a friend? How does friend affect access specification rules?

You can declare a function or class as friend of another class. When you do so the access specification rules do not apply to the friended class/function. The class or function can access all the members of that particular class.

So do friends break Encapsulation?

No they don't, On the contrary they enhance Encapsulation!

friendship is used to indicate a intentional strong coupling between two entities.
If there exists a special relationship between two entities such that one needs access to others private or protected members but You do not want everyone to have access by using the public access specifier then you should use friendship.

This looks like a good reference although it's not in Regex.

Really, unless you're actually shipping something to your users, I don't think it's worth the effort. And if you are shipping it, there are address cleaning tools/services you can look into to make it way easier on yourself.

Well, just to be different, I found an article that references using Reflection.Emit to do so.

Here's the link: http://www.codeproject.com/KB/cs/dotnetattributes.aspx , you will also want to look into some of the comments at the bottom of the article, because possible approaches are discussed.

Take a look here in order to get started: http://instagram.com/developer/

and then in order to retrieve pictures by tag, look here: http://instagram.com/developer/endpoints/tags/

Getting tags from Instagram doesn't require OAuth, so you can make the calls via these URLs:

GET IMAGES https://api.instagram.com/v1/tags/{tag-name}/media/recent?access_token={TOKEN}

SEARCH https://api.instagram.com/v1/tags/search?q={tag-query}&access_token={TOKEN}

TAG INFO https://api.instagram.com/v1/tags/{tag-name}?access_token={TOKEN}

_.get(obj, 'address.street.name') works great for JavaScript where you have no types. But for TypeScript we need the real Elvis operator!

Your first file has Mac Classic line endings (that’s "\r" instead of the usual "\n"). Open it with

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

Indeed worked for me whereas I couldn't use PHP

Just tested that it worked thanks to the approach mentioned above in some of the answers, so quick and verified that worked

For what I understand, VSCode is not in AppData anymore.

So Set the default git editor by executing that command in a command prompt window:

git config --global core.editor "'C:\Program Files (x86)\Microsoft VS Code\code.exe' -w"

The parameter -w, --wait is to wait for window to be closed before returning. Visual Studio Code is base on Atom Editor. if you also have atom installed execute the command atom --help. You will see the last argument in the help is wait.

Next time you do a git rebase -i HEAD~3 it will popup Visual Studio Code. Once VSCode is close then Git will take back the lead.

Note: My current version of VSCode is 0.9.2

I hope that help.

I am using ipinfodb.com api and getting exactly what you are looking for.

Its completely free, you just need to register with them to get your api key. You can include their php class by downloading from their website or you can use url format to retrieve information.

Here's what I am doing:

I included their php class in my script and using the below code:

$ipLite = new ip2location_lite;
$ipLite->setKey('your_api_key');
if(!$_COOKIE["visitorCity"]){ //I am using cookie to store information
  $visitorCity = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
  if ($visitorCity['statusCode'] == 'OK') {
    $data = base64_encode(serialize($visitorCity));
    setcookie("visitorCity", $data, time()+3600*24*7); //set cookie for 1 week
  }
}
$visitorCity = unserialize(base64_decode($_COOKIE["visitorCity"]));
echo $visitorCity['countryName'].' Region'.$visitorCity['regionName'];

Thats it.

This seems to work for me:

<html>
<head>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
// has the google object loaded?
if (window.google && window.google.load) {
    google.load("jquery", "1.3.2");
} else {
    document.write('<script type="text/javascript" src="http://joecrawford.com/jquery-1.3.2.min.js"><\/script>');
}
window.onload = function() {
    $('#test').css({'border':'2px solid #f00'});
};
</script>
</head>
<body>
    <p id="test">hello jQuery</p>
</body>
</html>

The way it works is to use the google object that calling http://www.google.com/jsapi loads onto the window object. If that object is not present, we are assuming that access to Google is failing. If that is the case, we load a local copy using document.write. (I'm using my own server in this case, please use your own for testing this).

I also test for the presence of window.google.load - I could also do a typeof check to see that things are objects or functions as appropriate. But I think this does the trick.

Here's just the loading logic, since code highlighting seems to fail since I posted the whole HTML page I was testing:

if (window.google && window.google.load) {
    google.load("jquery", "1.3.2");
} else {
    document.write('<script type="text/javascript" src="http://joecrawford.com/jquery-1.3.2.min.js"><\/script>');
}

Though I must say, I'm not sure that if this is a concern for your site visitors you should be fiddling with the Google AJAX Libraries API at all.

Fun fact: I tried initially to use a try..catch block for this in various versions but could not find a combination that was as clean as this. I'd be interested to see other implementations of this idea, purely as an exercise.

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

Good Luck...

Deployment keys are read only. To enable write access you need to:

• Remove this deployment key from your repository settings. You won't be able to write to this repo with this key anyway.

• Go to "Avatar -> Settings -> SSH Keys" and add the same key

• Now try to push to remove branch

You were able to write to repositories before but this is a change in BitBucket where you're no longer able to write with deploy key.

You could just use another non-regex based method. Someone gave the suggestion of using Substring, but you could also use Split:

string testString = "my-string";
string[] splitString = testString.Split("-");
string resultingString = splitString[0]; //my

See http://msdn.microsoft.com/en-US/library/ms228388%28v=VS.80%29.aspx for another good example.

        string sql =  "ALTER DATABASE "  + dataBase + "SET SINGLE_USER WITH ROLLBACK IMMEDIATE" ;

        using (System.Data.SqlClient.SqlConnection connection = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["DBRestore"].ConnectionString))
        {
            connection.Open();
            using (System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand(sql, connection))
            {

            }
        }
    }

For reference from SQL Server 2016 SP1+ you could use CREATE OR ALTER VIEW syntax.

MSDN CREATE VIEW:

CREATE [ OR ALTER ] VIEW [ schema_name . ] view_name [ (column [ ,...n ] ) ]   
[ WITH <view_attribute> [ ,...n ] ]   
AS select_statement   
[ WITH CHECK OPTION ]   
[ ; ]

OR ALTER

Conditionally alters the view only if it already exists.

You can also do it this way, allowing polymorphism:

class Base {
public:
   virtual std::ostream& dump(std::ostream& o) const {
      return o << "Base: " << b << "; ";
   }
private:
  int b;
};

class Derived : public Base {
public:
   virtual std::ostream& dump(std::ostream& o) const {
      return o << "Derived: " << d << "; ";
   }
private:
   int d;
}

std::ostream& operator<<(std::ostream& o, const Base& b) { return b.dump(o); }

The solutions suggested by S.Mark and SilentGhost generally tell you how it should be done in a Pythonic way, but I thought you might also benefit from knowing why your solution doesn't work. The problem is that as soon as you find the first common element in the two lists, you return that single element only. Your solution could be fixed by creating a result list and collecting the common elements in that list:

def common_elements(list1, list2):
    result = []
    for element in list1:
        if element in list2:
            result.append(element)
    return result

An even shorter version using list comprehensions:

def common_elements(list1, list2):
    return [element for element in list1 if element in list2]

However, as I said, this is a very inefficient way of doing this -- Python's built-in set types are way more efficient as they are implemented in C internally.

Your application (Eclipse) needs more memory and JVM is not allocating enough.You can increase the amount of memory JVM allocates by following the answers given here

If you are using CocoaPods and you want to disable Bitcode for all libraries, use the following command in the Podfile

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['ENABLE_BITCODE'] = 'NO'
        end
    end
end

i was having same problem with this error. It turn out my Kenel.php is having a wrong syntax when i try to comply with wrong php8 syntax

The line should be

protected $commands = [
    //
];

instead of

protected array $commands = [
        //
];

In Xterm-compatible terminals, you can show the image directly in the terminal. See my answer to "PPM image to ASCII art in Python"

Please note that this only work with python 2.x

You should try using the PyTTSx package since PyTTS is outdated. PyTTSx works with the lastest python version.

I like np.dot (dot product):

a = numpy.array((xa,ya,za))
b = numpy.array((xb,yb,zb))

distance = (np.dot(a-b,a-b))**.5

I'm not sure when this was added to the AWSCLI given that the original question was 3 years ago, but the command line tool gives a nice summary by running:

aws s3 ls s3://mybucket --recursive --human-readable --summarize

Inset box-shadow does the trick.

select{
  -webkit-appearance: none;
  box-shadow: inset 0px 0px 0px 4px;
  border-radius: 0px;
  border: none;
  padding:20px 150px 20px 10px;
}

Demo

I was stuck in this and I solved it with a hidden field:

<form method="post" action="test.php">
    <input type="hidden" name="ID" value"">
</form>

In value you can add whatever you want to add.

In test.php you can retrieve the value through $_Post[ID].

If you want to find how many processors (or CPUs) a machine has the same way %NUMBER_OF_PROCESSORS% shows you the number of cores, save the following script in a batch file, for example, GetNumberOfCores.cmd:

@echo off
for /f "tokens=*" %%f in ('wmic cpu get NumberOfCores /value ^| find "="') do set %%f

And then execute like this:

GetNumberOfCores.cmd

echo %NumberOfCores%

The script will set a environment variable named %NumberOfCores% and it will contain the number of processors.

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

Let's see both the options:

1.) Use PHP inside Javascript

<script>
    <?php $temp = 'hello';?>
    console.log('<?php echo $temp; ?>');
</script>

Note: File name should be in .php only.

2.) Use Javascript variable inside PHP

<script>
  var res = "success";
</script>
<?php
   echo "<script>document.writeln(res);</script>";
?>

Based on the @trincot answer, very good explained, I use WITH RECURSIVE () statement to create a breadcrumb using id of the current page and go backwards in the hierarchy to find the every parent in my route table.

So, the @trincot solution is adapted here in the opposite direction to find parents instead of descendants.

I also added depth value which is usefull to invert result order (otherwise the breadcrumb would be upside down).

WITH RECURSIVE cte (
    `id`,
    `title`,
    `url`,
    `icon`,
    `class`,
    `parent_id`,
    `depth`
) AS (
    SELECT   
        `id`,
        `title`,
        `url`,
        `icon`,
        `class`,
        `parent_id`,
        1 AS `depth` 
    FROM     `route`
    WHERE    `id` = :id
      
    UNION ALL 
    SELECT 
        P.`id`,
        P.`title`,
        P.`url`,
        P.`icon`,
        P.`class`,
        P.`parent_id`,
        `depth` + 1
    FROM `route` P
        
    INNER JOIN cte
        ON P.`id` = cte.`parent_id`
)
SELECT * FROM cte ORDER BY `depth` DESC;

Before upgrade to mySQL 8+, I was using vars but it's deprecated and no more working on my 8.0.22 version !

EDIT 2021-02-19 : Example for hierarchical menu

After @david comment I decided to try to make a full hierarchical menu with all nodes and sorted as I want (with sorting column which sort items in each depth). Very usefull for my user/authorization matrix page.

This really simplifies my old version with one query on each depth (PHP loops).

This example intergrates an INNER JOIN with url table to filter route by website (multi-websites CMS system).

You can see the essential path column that contains CONCAT() function to sort the menu in the right way.

SELECT R.* FROM (
    WITH RECURSIVE cte (
        `id`,
        `title`,
        `url`,
        `icon`,
        `class`,
        `parent`,
        `depth`,
        `sorting`,
        `path`
    ) AS (
        SELECT 
            `id`,
            `title`,
            `url`,
            `icon`,
            `class`,
            `parent`,
            1 AS `depth`,
            `sorting`,
            CONCAT(`sorting`, ' ' , `title`) AS `path`
        FROM `route`
        WHERE `parent` = 0
        UNION ALL SELECT 
            D.`id`,
            D.`title`,
            D.`url`,
            D.`icon`,
            D.`class`,
            D.`parent`,
            `depth` + 1,
            D.`sorting`,
            CONCAT(cte.`path`, ' > ', D.`sorting`, ' ' , D.`title`)
        FROM `route` D
        INNER JOIN cte
            ON cte.`id` = D.`parent`
    )
    SELECT * FROM cte
) R

INNER JOIN `url` U
    ON R.`id` = U.`route_id`
    AND U.`site_id` = 1

ORDER BY `path` ASC  

Calendar currentTime = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
currentTime.set(Calendar.ZONE_OFFSET, TimeZone.getTimeZone("UTC").getRawOffset());
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, currentTime.get(Calendar.HOUR_OF_DAY));
calendar.getTimeInMillis()

is working for me

Use Math.round().

(Alex's answer is better; I made an assumption :)

I am not sure what you mean by "dynamic". If you mean adding items to a dictionary at runtime, it is as easy as dictionary[key] = value.

If you wish to create a dictionary with key,value to start with (at compile time) then use (surprise!)

dictionary[key] = value

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
    {
      if (!char.IsControl(e.KeyChar) && !char.IsLetter(e.KeyChar) &&
         (e.KeyChar !='.'))
        { 
          e.Handled = true;
          MessageBox.Show("Only Alphabets");
        }
    }

Description:

there are 3 steps to run PHP code inside post or page.

1. In functions.php file (in your theme) add new function

2. In functions.php file (in your theme) register new shortcode which call your function:

add_shortcode( 'SHORCODE_NAME', 'FUNCTION_NAME' );

3. use your new shortcode

Example #1: just display text.

In functions:

function simple_function_1() {
    return "Hello World!";
}

add_shortcode( 'own_shortcode1', 'simple_function_1' );

In post/page:

[own_shortcode1]

Effect:

Hello World!

Example #2: use for loop.

In functions:

function simple_function_2() {
    $output = "";
    
    for ($number = 1; $number < 10; $number++) {    
        // Append numbers to the string
        $output .= "$number<br>";
    } 
    
    return "$output";
}

add_shortcode( 'own_shortcode2', 'simple_function_2' );

In post/page:

[own_shortcode2]

Effect:

1
2
3
4
5
6
7
8
9

Example #3: use shortcode with arguments

In functions:

function simple_function_3($name) {
    return "Hello $name";
}

add_shortcode( 'own_shortcode3', 'simple_function_3' );

In post/page:

[own_shortcode3 name="John"]

Effect:

Hello John

Example #3 - without passing arguments

In post/page:

[own_shortcode3]

Effect:

Hello 

This error can appear on the client if there is a problem on the server side. For example, if the SOAP server is a PHP script with a parse error, the client will fail with this message.

If you are in control of the server, tail your Apache error_log on the machine that hosts the SOAP server. On CentOS you will find this in /var/log/httpd/error_log, so the command is:

tail -f /var/log/httpd/error_log

Now refresh the client and watch for the error message. Any PHP errors with the server script will be shown.

Hope that helps someone.

An alternative using a closure to separate out the code into something a bit neater using Swift 4:

class theViewController: UIViewController {

    /** Create the UILabel */
    var theLabel: UILabel = {
        let label = UILabel()
        label.lineBreakMode = .byWordWrapping
        label.textColor = UIColor.white
        label.textAlignment = .left
        label.numberOfLines = 3
        label.font = UIFont(name: "Helvetica-Bold", size: 22)
        return label
    }()

    override func viewDidLoad() {
        /** Add theLabel to the ViewControllers view */
        view.addSubview(theLabel)
    }

    override func viewDidLayoutSubviews() {
        /* Set the frame when the layout is changed */
        theLabel.frame = CGRect(x: 0,
                                y: 0,
                                width: view.frame.width - 30,
                                height: 24)
    }
}

As a note, attributes for theLabel can still be changed whenever using functions in the VC. You're just setting various defaults inside the closure and minimizing clutter in functions like viewDidLoad()

I think you misunderstood what the java.io.File class really represents. It is just a representation of the file on your system, i.e. its name, its path etc.

Did you even look at the Javadoc for the java.io.File class? Have a look here If you check the fields it has or the methods or constructor arguments, you immediately get the hint that all it is, is a representation of the URL/path.

Oracle provides quite an extensive tutorial in their Java File I/O tutorial, with the latest NIO.2 functionality too.

With NIO.2 you can read it in one line using java.nio.file.Files.readAllBytes().

Similarly you can use java.nio.file.Files.write() to write all bytes in your byte array.

UPDATE

Since the question is tagged Android, the more conventional way is to wrap the FileInputStream in a BufferedInputStream and then wrap that in a ByteArrayInputStream. That will allow you to read the contents in a byte[]. Similarly the counterparts to them exist for the OutputStream.

When an unauthorized request comes in, the entire request is URL encoded, and added as a query string to the request to the authorization form, so I can see where this may result in a problem given your situation.

According to MSDN, the correct element to modify to reset maxQueryStringLength in web.config is the <httpRuntime> element inside the <system.web> element, see httpRuntime Element (ASP.NET Settings Schema). Try modifying that element.

I have just discovered a way to append text and its working fine at least.

 var text = 'Put any text here';
 $('#text').append(text);

You can change text according to your need.

Hope this helps.

SHOW ENGINE INNODB STATUS \G

Look for the Section -

TRANSACTIONS

We can use INFORMATION_SCHEMA Tables.

Useful Queries

To check about all the locks transactions are waiting for:

USE INFORMATION_SCHEMA;
SELECT * FROM INNODB_LOCK_WAITS;

A list of blocking transactions:

SELECT * 
FROM INNODB_LOCKS 
WHERE LOCK_TRX_ID IN (SELECT BLOCKING_TRX_ID FROM INNODB_LOCK_WAITS);

OR

SELECT INNODB_LOCKS.* 
FROM INNODB_LOCKS
JOIN INNODB_LOCK_WAITS
  ON (INNODB_LOCKS.LOCK_TRX_ID = INNODB_LOCK_WAITS.BLOCKING_TRX_ID);

A List of locks on particular table:

SELECT * FROM INNODB_LOCKS 
WHERE LOCK_TABLE = db_name.table_name;

A list of transactions waiting for locks:

SELECT TRX_ID, TRX_REQUESTED_LOCK_ID, TRX_MYSQL_THREAD_ID, TRX_QUERY
FROM INNODB_TRX
WHERE TRX_STATE = 'LOCK WAIT';

Reference - MySQL Troubleshooting: What To Do When Queries Don't Work, Chapter 6 - Page 96.

Bootstrap 3

You can create or just override default bootstrap modal-lgby doing below:

.modal-lg {
    max-width: 80%;
}

If not working just add !important so it would look like below

.modal-lg {
    max-width: 80% !important;
}

Now call the modal-lg.

<div class="modal-dialog modal-lg" role="document">
 <!-- some modal content --->
</div

For Bootstrap 4 refer to @kitsu.eb answer. Also note that using bootstrap 4 utilities might break the responsiveness.

This function allows you to get the date and time in lots of formats (see the bottom of this post).

# Get the current date or time
def getdatetime(timedateformat='complete'):
    from datetime import datetime
    timedateformat = timedateformat.lower()
    if timedateformat == 'day':
        return ((str(datetime.now())).split(' ')[0]).split('-')[2]
    elif timedateformat == 'month':
        return ((str(datetime.now())).split(' ')[0]).split('-')[1]
    elif timedateformat == 'year':
        return ((str(datetime.now())).split(' ')[0]).split('-')[0]
    elif timedateformat == 'hour':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
    elif timedateformat == 'minute':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1]
    elif timedateformat == 'second':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2]
    elif timedateformat == 'millisecond':
        return (str(datetime.now())).split('.')[1]
    elif timedateformat == 'yearmonthday':
        return (str(datetime.now())).split(' ')[0]
    elif timedateformat == 'daymonthyear':
        return ((str(datetime.now())).split(' ')[0]).split('-')[2] + '-' + ((str(datetime.now())).split(' ')[0]).split('-')[1] + '-' + ((str(datetime.now())).split(' ')[0]).split('-')[0]
    elif timedateformat == 'hourminutesecond':
        return ((str(datetime.now())).split(' ')[1]).split('.')[0]
    elif timedateformat == 'secondminutehour':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2] + ':' + (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1] + ':' + (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
    elif timedateformat == 'complete':
        return str(datetime.now())
    elif timedateformat == 'datetime':
        return (str(datetime.now())).split('.')[0]
    elif timedateformat == 'timedate':
        return ((str(datetime.now())).split('.')[0]).split(' ')[1] + ' ' + ((str(datetime.now())).split('.')[0]).split(' ')[0]

To obtain the time or date, just use getdatetime("<TYPE>"), replacing <TYPE> with one of the following arguments:

All example outputs use this model information: 25-11-2017 03:23:56.477017

    String str = "kushalhs , mayurvm , narendrabz ,";
    System.out.println(str.replaceAll(",([^,]*)$", "$1"));

Inside the input tag you can add autoFocus={true} for anyone using jsx/react.

<input
 type="email"
 name="email"
 onChange={e => setEmail(e.target.value)}
 value={email}
 placeholder={"Email..."}
 autoFocus={true}
/>

1. We need Git Bash
2. In Git Bash Command Section::

1.1 ls

It will show you default location.

1.2 CD "C:\Users\user\Desktop\HTML" We need to assign project path

1.3 git init It will initialize the empty git repository in C:\Users\user\Desktop\HTML

1.4 ls It will list all files name

1.5 git remote add origin https://github.com/repository/test.git it is your https://github.com/repository/test.git is your repository path

1.6 git remote -v To check weather we have fetch or push permisson or not

1.7 git add . If you put . then it mean whatever we have in perticular folder publish all.

1.8 git commit -m "First time"

1.9 git push -u origin master

As others have mentioned, a.update(b) for some dicts a and b will achieve the result you've asked for in your question. However, I want to point out that many times I have seen the extend method of mapping/set objects desire that in the syntax a.extend(b), a's values should NOT be overwritten by b's values. a.update(b) overwrites a's values, and so isn't a good choice for extend.

Note that some languages call this method defaults or inject, as it can be thought of as a way of injecting b's values (which might be a set of default values) in to a dictionary without overwriting values that might already exist.

Of course, you could simple note that a.extend(b) is nearly the same as b.update(a); a=b. To remove the assignment, you could do it thus:

def extend(a,b):
    """Create a new dictionary with a's properties extended by b,
    without overwriting.

    >>> extend({'a':1,'b':2},{'b':3,'c':4})
    {'a': 1, 'c': 4, 'b': 2}
    """
    return dict(b,**a)

Thanks to Tom Leys for that smart idea using a side-effect-less dict constructor for extend.

The official way to detect .NET 3.0 is described here

http://msdn.microsoft.com/en-us/library/aa480198.aspx

Flawed, because it requires the caller to have registry access permissions.

MSDN also mentions a technique for detecting .NET 3.5 by checking the User Agent string:

http://msdn.microsoft.com/en-us/library/bb909885.aspx

I think Microsoft should have done a better job than this.

This code basically reads a JSON array object and convert each row into an option in the spinner that is passed as a parameter:

public ArrayAdapter<String> getArrayAdapterFromArrayListForSpinner(ArrayList<JSONObject> aArrayList, String aField)
{
    ArrayAdapter<String> aArrayAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_spinner_item);
    aArrayAdapter.setDropDownViewResource(R.layout.multiline_spinner_dropdown_item); //android.R.layout.simple_spinner_dropdown_item
    try {
        for (int i = 0; i < aArrayList.size(); i++)
        {
            aArrayAdapter.add(aArrayList.get(i).getString(aField)); 
        }
    } catch (JSONException e) {
        e.printStackTrace();
        ShowMessage("Error while reading the JSON list");
    }
    return aArrayAdapter;       
}

1. To closed ideas,
2. To remove all folder and file C:/Users/UserName/.m2/org/*,
3. Open ideas and update Maven project,(right click on project -> maven->update maven project)
4. After that update the project.

Java allocates 2 of 2 bytes for character as it follows UTF-16. It occupies minimum 2 bytes while storing a character, and maximum of 4 bytes. There is no 1 byte or 3 bytes of storage for character.

You can set aliases for the columns that you are selecting:

$query = 'SELECT news.id AS newsId, user.id AS userId, [OTHER FIELDS HERE] FROM news JOIN users ON news.user = user.id'

First of all, a data model is an abstraction tool and a database model (or scheme/diagramm) is a modeling result.

Conceptual data model is DBMS-independent and covers functional/domain design area. The most known conceptual data model is "Entity-Relationship". Normally, you can reuse the conceptual scheme to produce different logical schemes not only relational.

Logical data model is intended to be implemented by some DBMS and corresponds mostly to the conceptual level of ANSI/SPARC architecture (proposed in 1975); this point gives some collisions of terminology. Zachman Framework tried to resolve this kind of collision ten years later introducing conceptual, logical and physical models.

There are many logical data models, and the most known is relational one.

So main differences of conceptual data model are the focusing on the domain and DBMS-independence whereas logical data model is the most abstract level of concrete DBMS you plan to use. Note that contemporary DBMS support several logical models at the same time.

You can also have a look to my book and to the article for more details.

After authentication is in place, JSON hijacking protection can take a variety of forms. Google appends while(1) into their JSON data, so that if any malicious script evaluates it, the malicious script enters an infinite loop.

In concurrent and/or asynchronous settings, you may want to verify that certain methods (e.g. delegates, event listeners, response handlers, you name it) are not called. Mocking frameworks aside, you can call fail() in those methods to fail the tests. Expired timeouts are another natural failure condition in such scenarios.

For example:

final CountDownLatch latch = new CountDownLatch(1);

service.asyncCall(someParameter, new ResponseHandler<SomeType>() {
    @Override
    public void onSuccess(SomeType result) {
        assertNotNull(result);
        // Further test assertions on the result
        latch.countDown();
    }

    @Override
    public void onError(Exception e) {
        fail(exception.getMessage());
        latch.countDown();
    }
});

if ( !latch.await(5, TimeUnit.SECONDS) ) {
    fail("No response after 5s");
}

For PLSQL version 9.0.0.1601

1. From the context menu of the Table, choose "Edit Data"
2. Insert or edit the data
3. Post change

You can try this code

import random
N = 5
count_list = range(1,N+1)
random.shuffle(count_list)

while count_list:
    value = count_list.pop()
    # do whatever you want with 'value'

A possibility is to have an iframe inside the outer form. The iframe contains the inner form. Make sure to use the <base target="_parent" /> tag inside the head tag of the iframe to make the form behave as part of the main page.

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

you can force UTF8 with force_encoding(Encoding::UTF_8):

Example:

<%= yield.force_encoding(Encoding::UTF_8) %>

You're tired and cant do any more work. You eat food. The energy spent looking for food, getting it and actually eating it consumes energy and is overhead!

Overhead is something wasted in order to accomplish a task. The goal is to make overhead very very small.

In computer science lets say you want to print a number, thats your task. But storing the number, the setting up the display to print it and calling routines to print it, then accessing the number from variable are all overhead.

I used ProcessBuilder but had the same issue. The issue was with using command as one String line (like I would type it in cmd) instead of String array. In example from above. If I ran

ProcessBuilder pb = new ProcessBuilder("C:/Program Files/WinRAR/winrar x myjar.jar *.* new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

I got an error. But if I ran

ProcessBuilder pb = new ProcessBuilder("C:/Program Files/WinRAR/winrar", "x", "myjar.jar", "*.*", "new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

everything was OK.

1. Install ILMerge as the other threads tell you to

2. Then go to the installation folder, by default C:\Program Files (x86)\Microsoft\ILMerge

3. Drag your Dll's and Exes to that folder

4. Shift-Rightclick in that folder and choose open command prompt

5. Write

   ilmerge myExe.exe Dll1.dll /out:merged.exe
   

   Note that you should write your exe first.

There you got your merged exe. This might not be the best way if your going to do this multiple times, but the simplest one for a one time use, I would recommend putting Ilmerge to your path.

Here's one more approach by using SET and FOR /F

@echo off

set "var=<?xml version="1.0" encoding="utf-8" ?>"

for /f "tokens=1* delims==" %%a in ('set var') do echo %%b

and you can beautify it like:

@echo off
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
set "print{[=for /f "tokens=1* delims==" %%a in ('set " & set "]}=') do echo %%b"
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::


set "xml_line.1=<?xml version="1.0" encoding="utf-8" ?>"
set "xml_line.2=<root>"
set "xml_line.3=</root>"

%print{[% xml_line %]}%

On Android platforms, Oruxmaps (http://www.oruxmaps.com) does a great job at caching all WMS sources. It is available in the play store. I use it daily in remote areas without any connectivity, works like a charm.

You can use -

$isTouch = isset($variable);

It will return true if the $variable is defined. if the variable is not defined it will return false.

Note : Returns TRUE if var exists and has value other than NULL, FALSE otherwise.

If you want to check for false, 0 etc You can then use empty() -

$isTouch = empty($variable);

empty() works for -

• "" (an empty string)
• 0 (0 as an integer)
• 0.0 (0 as a float)
• "0" (0 as a string)
• NULL
• FALSE
• array() (an empty array)
• $var; (a variable declared, but without a value)

This solution is not very different from those above, but for me it works very well and i think it's clean.

I suggest to base64 encode the file server side (base64_encode(), if you are using PHP) and send the base64 encoded data to the client

On the client you do this:

 let blob = this.dataURItoBlob(THE_MIME_TYPE + "," + response.file);
 let uri = URL.createObjectURL(blob);
 let link = document.createElement("a");
 link.download = THE_FILE_NAME,
 link.href = uri;
 document.body.appendChild(link);
 link.click();
 document.body.removeChild(link);

This code puts the encoded data in a link and simulates a click on the link, then it removes it.

I'm working on AWS Redshift, which does not support the COPY TO feature.

My BI tool supports tab-delimited CSVs though, so I used the following:

 psql -h dblocation -p port -U user -d dbname -F $'\t' --no-align -c "SELECT * FROM TABLE" > outfile.csv

I had the same error when we imported a key into a keystore that was build using a 64bit OpenSSL Version. When we followed the same procedure to import the key into a keystore that was build using a 32 bit OpenSSL version everything went fine.

You need to escape the % with another...

I know this answer is too late considering the question is dated 2010 but I came across this question as I was facing a similar problem myself. As already stated in the answer, normed=True means that the total area under the histogram is equal to 1 but the sum of heights is not equal to 1. However, I wanted to, for convenience of physical interpretation of a histogram, make one with sum of heights equal to 1.

I found a hint in the following question - Python: Histogram with area normalized to something other than 1

But I was not able to find a way of making bars mimic the histtype="step" feature hist(). This diverted me to : Matplotlib - Stepped histogram with already binned data

If the community finds it acceptable I should like to put forth a solution which synthesises ideas from both the above posts.

import matplotlib.pyplot as plt

# Let X be the array whose histogram needs to be plotted.
nx, xbins, ptchs = plt.hist(X, bins=20)
plt.clf() # Get rid of this histogram since not the one we want.

nx_frac = nx/float(len(nx)) # Each bin divided by total number of objects.
width = xbins[1] - xbins[0] # Width of each bin.
x = np.ravel(zip(xbins[:-1], xbins[:-1]+width))
y = np.ravel(zip(nx_frac,nx_frac))

plt.plot(x,y,linestyle="dashed",label="MyLabel")
#... Further formatting.

This has worked wonderfully for me though in some cases I have noticed that the left most "bar" or the right most "bar" of the histogram does not close down by touching the lowest point of the Y-axis. In such a case adding an element 0 at the begging or the end of y achieved the necessary result.

Just thought I'd share my experience. Thank you.

I really suggest following Google's Design Guidelines:

which says "Notification icons must be entirely white."

Controller function

Each directive's controller function is called whenever a new related element is instantiated.

Officially, the controller function is where one:

• Defines controller logic (methods) that may be shared between controllers.
• Initiates scope variables.

Again, it is important to remember that if the directive involves an isolated scope, any properties within it that inherit from the parent scope are not yet available.

Do:

• Define controller logic
• Initiate scope variables

Do not:

• Inspect child elements (they may not be rendered yet, bound to scope, etc.).

I had this problem but I fixed this by making sure my Code Signing Identity is the SAME as the one I used in test flight.

After that, everything works fine

Used the Accepted Answer to do a check for IE and convert the dataURI to UInt8Array; an accepted form by PDFJS

        Ext.isIE ? pdfAsDataUri = me.convertDataURIToBinary(pdfAsDataUri): '';_x000D_
_x000D_
        convertDataURIToBinary: function(dataURI) {_x000D_
          var BASE64_MARKER = ';base64,',_x000D_
            base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length,_x000D_
            base64 = dataURI.substring(base64Index),_x000D_
            raw = window.atob(base64),_x000D_
            rawLength = raw.length,_x000D_
            array = new Uint8Array(new ArrayBuffer(rawLength));_x000D_
_x000D_
          for (var i = 0; i < rawLength; i++) {_x000D_
            array[i] = raw.charCodeAt(i);_x000D_
          }_x000D_
          return array;_x000D_
        },

How about a workaround? In my case I took the value of the textarea in a jQuery variable, and changed all "<p>&nbsp" to <p class="clear"> and clear class to have certain height and margin, as the following example:

jQuery

tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p>&nbsp/g, '<p class="clear">');

the val is then saved to the database with the new val.

CSS

p.clear{height: 2px; margin-bottom: 3px;}

You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.

Hope that helps!

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

Try

sed 'NUMq;d'  /etc/*release | awk {'print $1}'

where NUM is line number

ex. sed '1q;d'  /etc/*release | awk {'print $1}'

To do this, you can reset you local git repository to the first commit hashtag, so all your changes after that commit will be unstaged, then you can commit with --amend option.

git reset your-first-commit-hashtag
git add .
git commit --amend

And then edit the first commit nam if needed and save file.

in case you are interested in reading some data from a .txt file and only extract few columns of that file into a new .txt file with a customized header, the following code might be useful:

# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")

# assign the name for the output file:
seqName <- "seq1_data.txt"

#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx        <- civit_cam$q.x.rad.
qy        <- civit_cam$q.y.rad.
qz        <- civit_cam$q.z.rad.
qw        <- civit_cam$q.w

# From GPS:
gpsT      <- civit_gps$X.gpsTime.sec.
latitude  <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude  <- civit_gps$H.Ell.m.
heading   <- civit_gps$Heading.deg.
pitch     <- civit_gps$pitch.deg.
roll      <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]

#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
                     c(frame_idx),
                     c(qx),
                     c(qy),
                     c(qz),
                     c(qw))
# Write :
cat("#GPSTime,frameIdx,qx,qy,qz,qw\n", file=seqName)
write.table(myData, file = seqName,row.names=FALSE,col.names=FALSE,append=TRUE,sep = ",")

Of course, you should modify this sample script based on your own application.

First.. a couple missing use-cases here if we're talking about ways to inject anonymous code..

code.compile_command()
code.interact()
imp.load_compiled()
imp.load_dynamic()
imp.load_module()
__builtin__.compile()
loading C compiled shared objects? example: _socket?)

But, the real question is, what is your goal - are you trying to enforce some sort of security? Or are you just interested in whats being loaded.

If you're interested in security, the filename that is being imported via exec/execfile is inconsequential - you should use rexec, which offers the following:

This module contains the RExec class, which supports r_eval(), r_execfile(), r_exec(), and r_import() methods, which are restricted versions of the standard Python functions eval(), execfile() and the exec and import statements. Code executed in this restricted environment will only have access to modules and functions that are deemed safe; you can subclass RExec add or remove capabilities as desired.

However, if this is more of an academic pursuit.. here are a couple goofy approaches that you might be able to dig a little deeper into..

Example scripts:

./deep.py

print ' >> level 1'
execfile('deeper.py')
print ' << level 1'

./deeper.py

print '\t >> level 2'
exec("import sys; sys.path.append('/tmp'); import deepest")
print '\t << level 2'

/tmp/deepest.py

print '\t\t >> level 3'
print '\t\t\t I can see the earths core.'
print '\t\t << level 3'

./codespy.py

import sys, os

def overseer(frame, event, arg):
    print "loaded(%s)" % os.path.abspath(frame.f_code.co_filename)

sys.settrace(overseer)
execfile("deep.py")
sys.exit(0)

Output

loaded(/Users/synthesizerpatel/deep.py)
>> level 1
loaded(/Users/synthesizerpatel/deeper.py)
    >> level 2
loaded(/Users/synthesizerpatel/<string>)
loaded(/tmp/deepest.py)
        >> level 3
            I can see the earths core.
        << level 3
    << level 2
<< level 1

Of course, this is a resource-intensive way to do it, you'd be tracing all your code.. Not very efficient. But, I think it's a novel approach since it continues to work even as you get deeper into the nest. You can't override 'eval'. Although you can override execfile().

Note, this approach only coveres exec/execfile, not 'import'. For higher level 'module' load hooking you might be able to use use sys.path_hooks (Write-up courtesy of PyMOTW).

Thats all I have off the top of my head.

C does not really have multi-dimensional arrays, but there are several ways to simulate them. The way to pass such arrays to a function depends on the way used to simulate the multiple dimensions:

1) Use an array of arrays. This can only be used if your array bounds are fully determined at compile time, or if your compiler supports VLA's:

#define ROWS 4
#define COLS 5

void func(int array[ROWS][COLS])
{
  int i, j;

  for (i=0; i<ROWS; i++)
  {
    for (j=0; j<COLS; j++)
    {
      array[i][j] = i*j;
    }
  }
}

void func_vla(int rows, int cols, int array[rows][cols])
{
  int i, j;

  for (i=0; i<rows; i++)
  {
    for (j=0; j<cols; j++)
    {
      array[i][j] = i*j;
    }
  }
}

int main()
{
  int x[ROWS][COLS];

  func(x);
  func_vla(ROWS, COLS, x);
}

2) Use a (dynamically allocated) array of pointers to (dynamically allocated) arrays. This is used mostly when the array bounds are not known until runtime.

void func(int** array, int rows, int cols)
{
  int i, j;

  for (i=0; i<rows; i++)
  {
    for (j=0; j<cols; j++)
    {
      array[i][j] = i*j;
    }
  }
}

int main()
{
  int rows, cols, i;
  int **x;

  /* obtain values for rows & cols */

  /* allocate the array */
  x = malloc(rows * sizeof *x);
  for (i=0; i<rows; i++)
  {
    x[i] = malloc(cols * sizeof *x[i]);
  }

  /* use the array */
  func(x, rows, cols);

  /* deallocate the array */
  for (i=0; i<rows; i++)
  {
    free(x[i]);
  }
  free(x);
}

3) Use a 1-dimensional array and fixup the indices. This can be used with both statically allocated (fixed-size) and dynamically allocated arrays:

void func(int* array, int rows, int cols)
{
  int i, j;

  for (i=0; i<rows; i++)
  {
    for (j=0; j<cols; j++)
    {
      array[i*cols+j]=i*j;
    }
  }
}

int main()
{
  int rows, cols;
  int *x;

  /* obtain values for rows & cols */

  /* allocate the array */
  x = malloc(rows * cols * sizeof *x);

  /* use the array */
  func(x, rows, cols);

  /* deallocate the array */
  free(x);
}

4) Use a dynamically allocated VLA. One advantage of this over option 2 is that there is a single memory allocation; another is that less memory is needed because the array of pointers is not required.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

extern void func_vla(int rows, int cols, int array[rows][cols]);
extern void get_rows_cols(int *rows, int *cols);
extern void dump_array(const char *tag, int rows, int cols, int array[rows][cols]);

void func_vla(int rows, int cols, int array[rows][cols])
{
    for (int i = 0; i < rows; i++)
    {
        for (int j = 0; j < cols; j++)
        {
            array[i][j] = (i + 1) * (j + 1);
        }
    }
}

int main(void)
{
    int rows, cols;

    get_rows_cols(&rows, &cols);

    int (*array)[cols] = malloc(rows * cols * sizeof(array[0][0]));
    /* error check omitted */

    func_vla(rows, cols, array);
    dump_array("After initialization", rows, cols, array);

    free(array);
    return 0;
}

void dump_array(const char *tag, int rows, int cols, int array[rows][cols])
{
    printf("%s (%dx%d):\n", tag, rows, cols);
    for (int i = 0; i < rows; i++)
    {
        for (int j = 0; j < cols; j++)
            printf("%4d", array[i][j]);
        putchar('\n');
    }
}

void get_rows_cols(int *rows, int *cols)
{
    srand(time(0));           // Only acceptable because it is called once
    *rows = 5 + rand() % 10;
    *cols = 3 + rand() % 12;
}

(See srand() — why call it only once?.)

where 'n' is some number of arrays, maybe an array of arrays . . .

var answer = _.reduce(n, function(a, b){ return a.concat(b)})

Unless you're really worried about older browsers, you could just use the new html5 placeholder attribute like so:

<input type="text" name="email" placeholder="Email address" class="input" />

The problem sometimes occurs when there are errors in the project.

For instance, if your project is configured with a target of 3.2 but the 3.2 libraries are not available, you will not be able to change the version to 4.0!

The usual (perhaps brutal) solution I use is to create a new project with the correct target and copy src, res and manifest into the new project.

Update:

This seems to work:

1. Change the selected through the build properties as normal
2. Manually edit project.properties AND default.properties to make sure they both reflect the desired target.
3. Close the project and re-open it

I always run Android Tools | Fix Project Properties after making any changes to the build target.

I generally like the shorthand version:

if (!!wlocation) { window.location = wlocation; }

I also face this problem sometimes. Click on gradle console in bottom bar of android studio, at right side. It will show the exact error in logs. My problem was that I had compile SDK 22 and imported appcomact library was of sdk 23.

You are mixing tabs and spaces. Don't do that. Specifically, the __init__ function body is indented with tabs while your on_data method is not.

Here is a screenshot of your code in my text editor; I set the tab stop to 8 spaces (which is what Python uses) and selected the text, which causes the editor to display tabs with continuous horizontal lines:

You have your editor set to expanding tabs to every fourth column instead, so the methods appear to line up.

Run your code with:

python -tt scriptname.py

and fix all errors that finds. Then configure your editor to use spaces only for indentation; a good editor will insert 4 spaces every time you use the TAB key.

Double click and open the server. Go to 'Arguments'. -Dcatalina.base= .. something. Go to that something. Your logs are there.

1. If the svg file has a height and width already defined width="100" height="100" in the svg file then add this x="0px" y="0px" width="100" height="100" viewBox="0 0 100 100" while keeping the already defined width="100" height="100".
2. Then you can scale the svg in your css file by using a selector in your case img so you could then do this: img{height: 20px; width: 20px;} and the image will scale.

When using a remotely mounted homedrive (Samba share, NFS, ...) your ~/.git folder is shared across all systems which can lead to several problems. Thus I prefer a script to determine the right editor for the right system:

#!/usr/bin/perl
# Detect which system I'm on and choose the right editor
$unamea = `uname -a`;
if($unamea =~ /mingw/i){
    if($unamea =~ /devsystem/i){#Check hostname
        exec('C:\Program Files (x86)\Notepad++\notepad++.exe', '-multiInst', '-nosession', @ARGV);
    }
    if($unamea =~ /testsystem/i){
        exec('C:\Program Files\Notepad++\notepad++.exe', '-multiInst', '-nosession', @ARGV);
    }
}
$MCEDIT=`which mcedit`;
if($MCEDIT =~ /mcedit/){
    exec($MCEDIT, @ARGV);
}
$NANO=`which nano`;
if($NANO =~ /nano/){
    exec($NANO, @ARGV);
}
die "You don't have a suitable editor!\n";

One might consider a plain shell script, but I used Perl as it is shipped with msysgit and your Unix-like systems will usually provide one as well. Putting the script in /home/username/bin, which should be added to PATH in .bashrc or .profile. Once added with git config --global core.editor giteditor.pl you have the right editor, wherever you are.

A bit late to the party but I use my tried and trusted JS that takes advantage of Modernizr. Can be copy/pasted and applied to any project. Works every time:

// Placeholder fallback
if(!Modernizr.input.placeholder){

    $('[placeholder]').focus(function() {
      var input = $(this);
      if (input.val() == input.attr('placeholder')) {
        input.val('');
        input.removeClass('placeholder');
      }
    }).blur(function() {
      var input = $(this);
      if (input.val() == '' || input.val() == input.attr('placeholder')) {
        input.addClass('placeholder');
        input.val(input.attr('placeholder'));
      }
    }).blur();
    $('[placeholder]').parents('form').submit(function() {
      $(this).find('[placeholder]').each(function() {
        var input = $(this);
        if (input.val() == input.attr('placeholder')) {
          input.val('');
        }
      })
    });

}

Use this syntax:

CREATE TEMPORARY TABLE t1 (select * from t2);

Object equality check:JSON.stringify(array1.sort()) === JSON.stringify(array2.sort())

The above test also works with arrays of objects in which case use a sort function as documented in http://www.w3schools.com/jsref/jsref_sort.asp

Might suffice for small arrays with flat JSON schemas.

MVC defaults to DenyGet to protect you against a very specific attack involving JSON requests to improve the liklihood that the implications of allowing HTTP GET exposure are considered in advance of allowing them to occur.

This is opposed to afterwards when it might be too late.

Note: If your action method does not return sensitive data, then it should be safe to allow the get.

Further reading from my Wrox ASP.NET MVC3 book

By default, the ASP.NET MVC framework does not allow you to respond to an HTTP GET request with a JSON payload. If you need to send JSON in response to a GET, you'll need to explicitly allow the behavior by using JsonRequestBehavior.AllowGet as the second parameter to the Json method. However, there is a chance a malicious user can gain access to the JSON payload through a process known as JSON Hijacking. You do not want to return sensitive information using JSON in a GET request. For more details, see Phil's post at http://haacked.com/archive/2009/06/24/json-hijacking.aspx/ or this SO post.

With most recents browsers (starting with Firefox 21, Chrome 27, or IE 10), this is no more a vulnerability.

I would recommend a combination of PatIndex and Left. Carefully constructed, you can write a query that always works, no matter what your data looks like.

Ex:

Declare @Temp Table(Data VarChar(20))

Insert Into @Temp Values('BTA200')
Insert Into @Temp Values('BTA50')
Insert Into @Temp Values('BTA030')
Insert Into @Temp Values('BTA')
Insert Into @Temp Values('123')
Insert Into @Temp Values('X999')

Select Data, Left(Data, PatIndex('%[0-9]%', Data + '1') - 1)
From   @Temp

PatIndex will look for the first character that falls in the range of 0-9, and return it's character position, which you can use with the LEFT function to extract the correct data. Note that PatIndex is actually using Data + '1'. This protects us from data where there are no numbers found. If there are no numbers, PatIndex would return 0. In this case, the LEFT function would error because we are using Left(Data, PatIndex - 1). When PatIndex returns 0, we would end up with Left(Data, -1) which returns an error.

There are still ways this can fail. For a full explanation, I encourage you to read:

Extracting numbers with SQL Server

That article shows how to get numbers out of a string. In your case, you want to get alpha characters instead. However, the process is similar enough that you can probably learn something useful out of it.

In Apache 2.4, the authorization configuration syntax has changed, and the Order, Deny or Allow directives should no longer be used.

The new way to do this would be:

<VirtualHost *:8080>
    <Location />
        Require ip 192.168.1.0
    </Location>
    ...
</VirtualHost>

Further examples using the new syntax can be found in the Apache documentation: Upgrading to 2.4 from 2.2

What worked for me :

  $where = '';
   /* $this->db->like('ust.title',$query_data['search'])
        ->or_like('usr.f_name',$query_data['search'])
        ->or_like('usr.l_name',$query_data['search']);*/
        $where .= "(ust.title like '%".$query_data['search']."%'";
        $where .= " or usr.f_name like '%".$query_data['search']."%'";
        $where .= "or usr.l_name like '%".$query_data['search']."%')";
        $this->db->where($where);



$datas = $this->db->join(TBL_USERS.' AS usr','ust.user_id=usr.id')
            ->where_in('ust.id', $blog_list) 
            ->select('ust.*,usr.f_name as f_name,usr.email as email,usr.avatar as avatar, usr.sex as sex')
            ->get_where(TBL_GURU_BLOG.' AS ust',[
                'ust.deleted_at'     =>  NULL,
                'ust.status'     =>  1,
            ]); 

I have to do this to create a query like this :

SELECT `ust`.*, `usr`.`f_name` as `f_name`, `usr`.`email` as `email`, `usr`.`avatar` as `avatar`, `usr`.`sex` as `sex` FROM `blog` AS `ust` JOIN `users` AS `usr` ON `ust`.`user_id`=`usr`.`id` WHERE (`ust`.`title` LIKE '%mer%' ESCAPE '!' OR  `usr`.`f_name` LIKE '%lok%' ESCAPE '!' OR  `usr`.`l_name` LIKE '%mer%' ESCAPE '!') AND `ust`.`id` IN('36', '37', '38') AND `ust`.`deleted_at` IS NULL AND `ust`.`status` = 1 ;

In the Xcode 6.2, this also works

let appDelegate = UIApplication.sharedApplication().delegate! as AppDelegate

let aVariable = appDelegate.someVariable

You need to setup a SDK for Java projects, like @rizzletang said, but you don't need to create a new project, you can do it from the Welcome screen.

On the bottom right, select Configure > Project Defaults > Project Structure:

Picking the Project tab on the left will show that you have no SDK selected:

Just click the New... button on the right hand side of the dropdown and point it to your JDK. After that, you can go back to the import screen and it should just show up.

It is possible to get the response code of a http request using Selenium and Chrome or Firefox. All you have to do is start either Chrome or Firefox in logging mode. I will show you some examples below.

java + Selenium + Chrome Here is an example of java + Selenium + Chrome, but I guess that it can be done in any language (python, c#, ...).

All you need to do is tell chromedriver to do "Network.enable". This can be done by enabling Performance logging.

LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
cap.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);

After the request is done, all you have to do is get and iterate the Perfomance logs and find "Network.responseReceived" for the requested url:

LogEntries logs = driver.manage().logs().get("performance");

Here is the code:

    status code: 200

java + Selenium + Firefox I have finally found the trick for Firefox too. You need to start firefox using MOZ_LOG and MOZ_LOG_FILE environment variables, and log http requests at debug level (4 = PR_LOG_DEBUG) - map.put("MOZ_LOG", "timestamp,sync,nsHttp:4"). Save the log in a temporary file. After that, get the content of the saved log file and parse it for the response code (using some simple regular expressions). First detect the start of the request, identifying its id (nsHttpChannel::BeginConnect [this=000000CED8094000]), then at the second step, find the response code for that request id (nsHttpChannel::ProcessResponse [this=000000CED8094000 httpStatus=200]).

After discussing with the hosting of my SVN repository they gave me the following answer.

Apparently my repository is replicated to a remote repository using SVNSYNC. SVNSYNC has known limitations with enforcing locking across the replicated repositories and this is where the problem lies.

The locks were introduced by the AnkhSVN plugin in Visual Studio.

As the locks appears to be on the remote repository this explains why I can't actually see them using SVN commands.

The locks are being removed via the hosting company and hopefully all will soon be well again.

.wrappable { 
      overflow: hidden; 
      max-width: 400px; 
      word-wrap: break-word; 
}

I have tested with the binary data and its working perfectly here.

The other answers didn't work for me, but this did:

del /s /q *.svn
rmdir /s /q *.svn

/q disables Yes/No prompting

/s means delete the file(s) from all subdirectories.

Most of the answers need to read the whole file before doing anything. This sample reads increasingly large samples from the end.

I only saw Murat Yükselen's answer while writing this answer. It's nearly the same, which I suppose is a good thing. The sample below also deals with \r and increases its buffersize at each step. I also have some unit tests to back this code up.

def readlines_reversed(f):
    """ Iterate over the lines in a file in reverse. The file must be
    open in 'rb' mode. Yields the lines unencoded (as bytes), including the
    newline character. Produces the same result as readlines, but reversed.
    If this is used to reverse the line in a file twice, the result is
    exactly the same.
    """
    head = b""
    f.seek(0, 2)
    t = f.tell()
    buffersize, maxbuffersize = 64, 4096
    while True:
        if t <= 0:
            break
        # Read next block
        buffersize = min(buffersize * 2, maxbuffersize)
        tprev = t
        t = max(0, t - buffersize)
        f.seek(t)
        lines = f.read(tprev - t).splitlines(True)
        # Align to line breaks
        if not lines[-1].endswith((b"\n", b"\r")):
            lines[-1] += head  # current tail is previous head
        elif head == b"\n" and lines[-1].endswith(b"\r"):
            lines[-1] += head  # Keep \r\n together
        elif head:
            lines.append(head)
        head = lines.pop(0)  # can be '\n' (ok)
        # Iterate over current block in reverse
        for line in reversed(lines):
            yield line
    if head:
        yield head

Since NumPy version 1.13 it contains an isnat function:

>>> import numpy as np
>>> np.isnat(np.datetime64('nat'))
True

It also works for arrays:

>>> np.isnat(np.array(['nat', 1, 2, 3, 4, 'nat', 5], dtype='datetime64[D]'))
array([ True, False, False, False, False,  True, False], dtype=bool)

You could also pass points to the function: Small example:

def test(points):
    addpoint = raw_input ("type ""add"" to add a point")
    if addpoint == "add":
        points = points + 1
    else:
        print "asd"
    return points;
if __name__ == '__main__':
    points = 0
    for i in range(10):
        points = test(points)
        print points

It's a way to enforce a set of invariants of the abstract class. That is, no matter what the subclass does, you want to make sure some things are always true of the base class... example:

abstract class Foo
{
    public DateTime TimeCreated {get; private set;}

    protected Foo()
    {
         this.TimeCreated = DateTime.Now;
    }
}

abstract class Bar : Foo
{
    public Bar() : base() //Bar's constructor's must call Foo's parameterless constructor.
    { }
}

Don't think of a constructor as the dual of the new operator. The constructor's only purpose is to ensure that you have an object in a valid state before you start using it. It just happens to be that we usually call it through a new operator.

If you have your data in a text-file, you can use LOAD DATA INFILE.

When loading a table from a text file, use LOAD DATA INFILE. This is usually 20 times faster than using INSERT statements.

Optimizing INSERT Statements

You can find more tips on how to speed up your insert statements on the link above.

It can solve this problem by cd command, this command understand spaces without double quotes and you can call any program this way for example:

C:\Windows\system32>cd c:\Program Files\MongoDB\Server\3.2\bin

c:\Program Files\MongoDB\Server\3.2\bin>mongo now command prompt call mongo.exe

Make sure that your sas.png is marked as Build Action: Content and Copy To Output Directory: Copy Always in its Visual Studio Properties...

I think the C# source code goes like this...

Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;

and XAML should be

<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0" 
       Name="image1" Stretch="Fill" VerticalAlignment="Top" 
       Source="../Bilder/sas.png"
       Width="350" />  

EDIT

Dynamically I think XAML would provide best way to load Images ...

<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
       x:Name="MyImage"/>

where image.DataContext is string path.

MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";

public class MyImageSourceConverter : IValueConverter
{
    public object Convert(object value_, Type targetType_, 
    object parameter_, System.Globalization.CultureInfo culture_)
    {
        return (new ImageSourceConverter()).ConvertFromString (value.ToString());
    }

    public object ConvertBack(object value, Type targetType, 
    object parameter, CultureInfo culture)
    {
          throw new NotImplementedException();
    }
}

Now as you set a different data context, Image would be automatically loaded at runtime.

Grouping by will not work if the database rules don't allow any of the select fields to be outside of an aggregate function. Instead use the laravel collections.

$users = DB::table('users')
        ->select('id','name', 'email')
        ->get();

foreach($users->unique('name') as $user){
  //....
}

Someone pointed out that this may not be great on performance for large collections. I would recommend adding a key to the collection. The method to use is called keyBy. This is the simple method.

     $users = DB::table('users')
        ->select('id','name', 'email')
        ->get()
        ->keyBy('name');

The keyBy also allows you to add a call back function for more complex things...

     $users = DB::table('users')
        ->select('id','name', 'email')
        ->get()
        ->keyBy(function($user){
              return $user->name . '-' . $user->id;
         });

If you have to iterate over large collections, adding a key to it solve the performance issue.

use mkdirs() instead of mkdir()..it worked for me :)

File folder = new File(Environment.getExternalStorageDirectory()+"/Saved CGPA");
if(!folder.exists()){
    if(folder.mkdirs())
    Toast.makeText(this, "New Folder Created", Toast.LENGTH_SHORT).show();
}

File sdCardFile = new File(Environment.getExternalStorageDirectory()+"/Saved CGPA/cgpa.html");

cmake's ExternalProject_Add indeed can used, but what I did not like about it - is that it performs something during build, continuous poll, etc... I would prefer to build project during build phase, nothing else. I have tried to override ExternalProject_Add in several attempts, unfortunately without success.

Then I have tried also to add git submodule, but that drags whole git repository, while in certain cases I need only subset of whole git repository. What I have checked - it's indeed possible to perform sparse git checkout, but that require separate function, which I wrote below.

#-----------------------------------------------------------------------------
#
# Performs sparse (partial) git checkout
#
#   into ${checkoutDir} from ${url} of ${branch}
#
# List of folders and files to pull can be specified after that.
#-----------------------------------------------------------------------------
function (SparseGitCheckout checkoutDir url branch)
    if(EXISTS ${checkoutDir})
        return()
    endif()

    message("-------------------------------------------------------------------")
    message("sparse git checkout to ${checkoutDir}...")
    message("-------------------------------------------------------------------")

    file(MAKE_DIRECTORY ${checkoutDir})

    set(cmds "git init")
    set(cmds ${cmds} "git remote add -f origin --no-tags -t master ${url}")
    set(cmds ${cmds} "git config core.sparseCheckout true")

    # This command is executed via file WRITE
    # echo <file or folder> >> .git/info/sparse-checkout")

    set(cmds ${cmds} "git pull --depth=1 origin ${branch}")

    # message("In directory: ${checkoutDir}")

    foreach( cmd ${cmds})
        message("- ${cmd}")
        string(REPLACE " " ";" cmdList ${cmd})

        #message("Outfile: ${outFile}")
        #message("Final command: ${cmdList}")

        if(pull IN_LIST cmdList)
            string (REPLACE ";" "\n" FILES "${ARGN}")
            file(WRITE ${checkoutDir}/.git/info/sparse-checkout ${FILES} )
        endif()

        execute_process(
            COMMAND ${cmdList}
            WORKING_DIRECTORY ${checkoutDir}
            RESULT_VARIABLE ret
        )

        if(NOT ret EQUAL "0")
            message("error: previous command failed, see explanation above")
            file(REMOVE_RECURSE ${checkoutDir})
            break()
        endif()
    endforeach()

endfunction()


SparseGitCheckout(${CMAKE_BINARY_DIR}/catch_197 https://github.com/catchorg/Catch2.git v1.9.7 single_include)
SparseGitCheckout(${CMAKE_BINARY_DIR}/catch_master https://github.com/catchorg/Catch2.git master single_include)

I have added two function calls below just to illustrate how to use the function.

Someone might not like to checkout master / trunk, as that one might be broken - then it's always possible to specify specific tag.

Checkout will be performed only once, until you clear the cache folder.

I think it's vbcrlf.

replace(s, vbcrlf, "<br />")

You can't, at least not directly. That would be a nasty security risk.

While you can specify a Domain attribute, the specification says "The user agent will reject cookies unless the Domain attribute specifies a scope for the cookie that would include the origin server."

Since the origin server is a.com and that does not include b.com, it can't be set.

You would need to get b.com to set the cookie instead. You could do this via (for example) HTTP redirects to b.com and back.

NullPointerException with JSP can also happen if:

A getter returns a non-public inner class.

This code will fail if you remove Getters's access modifier or make it private or protected.

JAVA:

package com.myPackage;
public class MyClass{ 
    //: Must be public or you will get:
    //: org.apache.jasper.JasperException: 
    //: java.lang.NullPointerException
    public class Getters{
        public String 
        myProperty(){ return(my_property); }
    };;

    //: JSP EL can only access functions:
    private Getters _get;
    public  Getters  get(){ return _get; }

    private String 
    my_property;

    public MyClass(String my_property){
        super();
        this.my_property    = my_property;
        _get = new Getters();
    };;
};;

JSP

<%@ taglib uri   ="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import="com.myPackage.MyClass" %>
<%
    MyClass inst = new MyClass("[PROP_VALUE]");
    pageContext.setAttribute("my_inst", inst ); 
%><html lang="en"><body>
    ${ my_inst.get().myProperty() }
</body></html>

Here is how you do it: Simple way

// Initializing a new alert dialog
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.message);
builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        doAction();
    }
});
builder.setNegativeButton(R.string.cancel, null);

// Create the alert dialog and change Buttons colour
AlertDialog dialog = builder.create();
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface arg0) {
        dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.red));
        dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.blue));
        //dialog.getButton(AlertDialog.BUTTON_NEUTRAL).setTextColor(getResources().getColor(R.color.black));
    }
});
dialog.show();

Turn on grep's line buffering mode when using BSD grep (FreeBSD, Mac OS X etc.)

tail -f file | grep --line-buffered my_pattern

It looks like a while ago --line-buffered didn't matter for GNU grep (used on pretty much any Linux) as it flushed by default (YMMV for other Unix-likes such as SmartOS, AIX or QNX). However, as of November 2020, --line-buffered is needed (at least with GNU grep 3.5 in openSUSE, but it seems generally needed based on comments below).

et.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {

            et.setHint(temp +" Characters");
        }
    });

Set up a simple repository using a web server with its default configuration. The key is the directory structure. The documentation does not mention it explicitly, but it is the same structure as a local repository.

To set up an internal repository just requires that you have a place to put it, and then start copying required artifacts there using the same layout as in a remote repository such as repo.maven.apache.org. Source

Add a file to your repository like this:

mvn install:install-file \
  -Dfile=YOUR_JAR.jar -DgroupId=YOUR_GROUP_ID 
  -DartifactId=YOUR_ARTIFACT_ID -Dversion=YOUR_VERSION \
  -Dpackaging=jar \
  -DlocalRepositoryPath=/var/www/html/mavenRepository

If your domain is example.com and the root directory of the web server is located at /var/www/html/, then maven can find "YOUR_JAR.jar" if configured with <url>http://example.com/mavenRepository</url>.

Restarting the SQL Server will clear up the log space used by your database. If this however is not an option, you can try the following:

* Issue a CHECKPOINT command to free up log space in the log file.

* Check the available log space with DBCC SQLPERF('logspace'). If only a small 
  percentage of your log file is actually been used, you can try a DBCC SHRINKFILE 
  command. This can however possibly introduce corruption in your database. 

* If you have another drive with space available you can try to add a file there in 
  order to get enough space to attempt to resolve the issue.

Hope this will help you in finding your solution.

You can find some useful query here:

Investigating the Cause of SQL Server High CPU

For me this helped a lot:

SELECT s.session_id,
    r.status,
    r.blocking_session_id 'Blk by',
    r.wait_type,
    wait_resource,
    r.wait_time / (1000 * 60) 'Wait M',
    r.cpu_time,
    r.logical_reads,
    r.reads,
    r.writes,
    r.total_elapsed_time / (1000 * 60) 'Elaps M',
    Substring(st.TEXT,(r.statement_start_offset / 2) + 1,
    ((CASE r.statement_end_offset
WHEN -1
THEN Datalength(st.TEXT)
ELSE r.statement_end_offset
END - r.statement_start_offset) / 2) + 1) AS statement_text,
    Coalesce(Quotename(Db_name(st.dbid)) + N'.' + Quotename(Object_schema_name(st.objectid, st.dbid)) + N'.' +
    Quotename(Object_name(st.objectid, st.dbid)), '') AS command_text,
    r.command,
    s.login_name,
    s.host_name,
    s.program_name,
    s.last_request_end_time,
    s.login_time,
    r.open_transaction_count
FROM sys.dm_exec_sessions AS s
    JOIN sys.dm_exec_requests AS r
ON r.session_id = s.session_id
    CROSS APPLY sys.Dm_exec_sql_text(r.sql_handle) AS st
WHERE r.session_id != @@SPID
ORDER BY r.cpu_time desc

In the fields of status, wait_type and cpu_time you can find the most cpu consuming task that is running right now.

Alternative Method, 2020

Works well for headless servers. I was trying to download a ~200GB private file but couldn't get any of the other methods, mentioned in this thread, to work.

Solution

1. (Skip this step if the file is already in your own google drive) Make a copy of the file you want to download from a Public/Shared Folder into your Google Drive account. Select File -> Right Click -> Make a copy

2. Install and setup Rclone, an open-source command line tool, to sync files between your local storage and Google Drive. Here's a quick tutorial to install and setup rclone for Google Drive.

3. Copy your file from Google Drive to your machine using Rclone

rclone copy mygoogledrive:path/to/file /path/to/file/on/local/machine -P

-P argument helps to track progress of the download and lets you know when its finished.

jspdf does not work with css but it can work along with html2canvas. You can use jspdf along with html2canvas.

include these two files in script on your page :

<script type="text/javascript" src="html2canvas.js"></script>
  <script type="text/javascript" src="jspdf.min.js"></script>
  <script type="text/javascript">
  function genPDF()
  {
   html2canvas(document.body,{
   onrendered:function(canvas){

   var img=canvas.toDataURL("image/png");
   var doc = new jsPDF();
   doc.addImage(img,'JPEG',20,20);
   doc.save('test.pdf');
   }

   });

  }
  </script>

You need to download script files such as https://github.com/niklasvh/html2canvas/releases https://cdnjs.com/libraries/jspdf

make clickable button on page so that it will generate pdf and it will be seen same as that of original html page.

<a href="javascript:genPDF()">Download PDF</a>  

It will work perfectly.

It's not necessary to call repaint unless you need to render something specific onto a component. "Something specific" meaning anything that isn't provided internally by the windowing toolkit you're using.

cq.select(cb.construct(entityClazz.class, root.get("ID"), root.get("VERSION")));  // HERE IS NO ERROR

https://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Basic_JPA_Development/Querying/Criteria#Constructors

I had the same error. To fix the error:

1. Open the console menu Gallery Menu and select API Manager.
2. On the left, click Credentials and then click New Credentials.
3. Click Create Credentials.
4. Click API KEY.
5. Click Navigator Key (there are more options; It depends on when consumed).

You must use this new API Navigator Key, generated by the system.

Faster option:

The following code will copy your Pandas DF to postgres DB much faster than df.to_sql method and you won't need any intermediate csv file to store the df.

Create an engine based on your DB specifications.

Create a table in your postgres DB that has equal number of columns as the Dataframe (df).

Data in DF will get inserted in your postgres table.

from sqlalchemy import create_engine
import psycopg2 
import io

if you want to replace the table, we can replace it with normal to_sql method using headers from our df and then load the entire big time consuming df into DB.

engine = create_engine('postgresql+psycopg2://username:password@host:port/database')

df.head(0).to_sql('table_name', engine, if_exists='replace',index=False) #drops old table and creates new empty table

conn = engine.raw_connection()
cur = conn.cursor()
output = io.StringIO()
df.to_csv(output, sep='\t', header=False, index=False)
output.seek(0)
contents = output.getvalue()
cur.copy_from(output, 'table_name', null="") # null values become ''
conn.commit()

You can try this query in any given SQL Server database:

SELECT 
    name,
    create_date,
    modify_date
FROM sys.procedures
WHERE create_date = '20120927'  

which lists out the name, the creation and the last modification date - unfortunately, it doesn't record who created and/or modified the stored procedure in question.

I had the same error for quite a while, and here what fixed it for me.

I simply declared in service that i use what follows:

What should catch your attention here is "After=network.target". I spent days and days looking for fixes on nginx side, while the problem was just that. To be sure, stop running the node service you have, launch the ExecStart command directly and try to reproduce the bug. If it doesn't pop, it just means that your service has a problem. At least this is how i found my answer.

For everybody else, good luck!

There is at least one more way to do this using LINQ, although not the easiest. You can do it by using the OrberBy() method that uses an IComparer. First you need to implement an IComparer for the Movie class like this:

public class MovieComparer : IComparer<Movie>
{
    public int Compare(Movie x, Movie y)
    {
        if (x.CategoryId == y.CategoryId)
        {
            return x.Name.CompareTo(y.Name);
        }
        else
        {
            return x.CategoryId.CompareTo(y.CategoryId);
        }
    }
}

Then you can order the movies with the following syntax:

var movies = _db.Movies.OrderBy(item => item, new MovieComparer());

If you need to switch the ordering to descending for one of the items just switch the x and y inside the Compare() method of the MovieComparer accordingly.

If you need a single fadeIn/Out without an explicit user action (like a mouseover/mouseout) you may use a CSS3 animation: http://codepen.io/anon/pen/bdEpwW

.elementToFadeInAndOut {

    animation: fadeinout 4s linear 1 forwards;
}



@keyframes fadeinout {
  0% { opacity: 0; }
  50% { opacity: 1; }
  100% { opacity: 0; }
}

By setting animation-fill-mode: forwards the animation will retain its last keyframe

By setting animation-iteration-count: 1 the animation will run just once (change this value if you need to repeat the effect more than once)

As @Hutch pointed out, one of the major limitations of sp_who2 is that it does not take any parameters so you cannot sort or filter it by default. You can save the results into a temp table, but then the you have to declare all the types ahead of time (and remember to DROP TABLE).

Instead, you can just go directly to the source on master.dbo.sysprocesses

I've constructed this to output almost exactly the same thing that sp_who2 generates, except that you can easily add ORDER BY and WHERE clauses to get meaningful output.

SELECT  spid,
        sp.[status],
        loginame [Login],
        hostname, 
        blocked BlkBy,
        sd.name DBName, 
        cmd Command,
        cpu CPUTime,
        physical_io DiskIO,
        last_batch LastBatch,
        [program_name] ProgramName   
FROM master.dbo.sysprocesses sp 
JOIN master.dbo.sysdatabases sd ON sp.dbid = sd.dbid
ORDER BY spid 

What's you've got there should be fine to work, but there is no actual "Is Mobile/Tablet" media query so you're always going to be stuck.

There are media queries for common breakpoints , but with the ever changing range of devices they're not guaranteed to work moving forwards.

The idea is that your site maintains the same brand across all sizes, so you should want the styles to cascade across the breakpoints and only update the widths and positioning to best suit that viewport.

To further the answer above, using Modernizr with a no-touch test will allow you to target touch devices which are most likely tablets and smart phones, however with the new releases of touch based screens that is not as good an option as it once was.

Just had this problem (again!) after getting a new Lion box.

Best solution I've found (still not 100% optimal, but working):

• make sure you have 64-bit python. How to check if a library is 32bit/64bit built on Mac OS X?

• install easy_install if you don't have it. http://packages.python.org/distribute/easy_install.html

• install GCC if you don't have it.

you can get it by downloading XCode/Dev Tools from Apple - this is a big download -

... but instead I recommend this github which has what you need (and does not have XCode): https://github.com/kennethreitz/osx-gcc-installer

I downloaded their prebuilt PKG for lion, https://github.com/downloads/kennethreitz/osx-gcc-installer/GCC-10.7-v2.pkg

• make sure you have downloaded a 64-BIT version of MYSQL Community. (The DMG install is an easy route) http://dev.mysql.com/downloads/mysql/

• Set paths as follows:

  export PATH=$PATH:/usr/local/mysql-XXXX

  export DYLD_LIBRARY_PATH = /usr/local/mysql/lib/

  export ARCHFLAGS='-arch x86_64'

NOTE THAT:

1 in mysql-XXXX above, XXX is the specific version you downloaded. (Probably /usr/local/mysql/ would also work since this is most likely an alias to the same, but I won't pretend to know your setup)

2 I have seen it suggested that ARCHFLAGS be set to '-arch i386 -arch x86_64' but specifying only x86_64 seemed to work better for me. (I can think of some reasons for this but they are not strictly relevant).

• Install the beast!

  easy_install MySQL-python

• LAST STEP:

Permanently add the DYLD_LIBRARY_PATH!

You can add it to your bash_profile or similar. This was the missing step for me, without which my system continued to insist on various errors finding _mysql.so and so on.

export DYLD_LIBRARY_PATH = /usr/local/mysql/lib/

@richard-boardman, just noticed your soft link solution, which may in effect be doing the same thing my PATH solution does...folks, whatever works best for you.

Best reference: http://activeintelligence.org/blog/archive/mysql-python-aka-mysqldb-on-osx-lion/

Jon, you have some syntax errors, see below, this worked for me.

  <script type="text/javascript">
$(document).ready(function () {

  $.validator.addMethod(
      "australianDate",
      function (value, element) {
        // put your own logic here, this is just a (crappy) example 
        return value.match(/^\d\d?\/\d\d?\/\d\d\d\d$/);
      },
      "Please enter a date in the format dd/mm/yyyy"
    );

  $('#testForm').validate({
    rules: {
      "myDate": {
        australianDate: true
      }
    }
  });

});             

Using jQuery will make this simpler.

The following code will take an array of arrays and store convert them into rows and cells.

$.getJSON(url , function(data) {
    var tbl_body = "";
    var odd_even = false;
    $.each(data, function() {
        var tbl_row = "";
        $.each(this, function(k , v) {
            tbl_row += "<td>"+v+"</td>";
        });
        tbl_body += "<tr class=\""+( odd_even ? "odd" : "even")+"\">"+tbl_row+"</tr>";
        odd_even = !odd_even;               
    });
    $("#target_table_id tbody").html(tbl_body);
});

You could add a check for the keys you want to exclude by adding something like

var expected_keys = { key_1 : true, key_2 : true, key_3 : false, key_4 : true };

at the start of the getJSON callback function and adding:

if ( ( k in expected_keys ) && expected_keys[k] ) {
...
}

around the tbl_row += line.

Edit: Was assigning a null variable previously

Edit: Version based on Timmmm's injection-free contribution.

$.getJSON(url , function(data) {
    var tbl_body = document.createElement("tbody");
    var odd_even = false;
    $.each(data, function() {
        var tbl_row = tbl_body.insertRow();
        tbl_row.className = odd_even ? "odd" : "even";
        $.each(this, function(k , v) {
            var cell = tbl_row.insertCell();
            cell.appendChild(document.createTextNode(v.toString()));
        });        
        odd_even = !odd_even;               
    });
    $("#target_table_id").append(tbl_body);   //DOM table doesn't have .appendChild
});

A version that avoids creating a sub-process:

for D in *; do
    if [ -d "${D}" ]; then
        echo "${D}"   # your processing here
    fi
done

Or, if your action is a single command, this is more concise:

for D in *; do [ -d "${D}" ] && my_command; done

Or an even more concise version (thanks @enzotib). Note that in this version each value of D will have a trailing slash:

for D in */; do my_command; done

You have to allocate more space to the PermGenSpace of the tomcat JVM.

This can be done with the JVM argument : -XX:MaxPermSize=128m

By default, the PermGen space is 64M (and it contains all compiled classes, so if you have a lot of jar (classes) in your classpath, you may indeed fill this space).

On a side note, you can monitor the size of the PermGen space with JVisualVM and you can even inspect its content with YourKit Java Profiler

homebrew/science was deprecated So, you should use the following command.

brew tap brewsci/science

Another potential cause for this error: Attempting to get permission for a Facebook app in sandbox mode when the Facebook user is not listed in the app's admins, developers or testers.

It is O(1) only if your hashing function is very good. The Java hash table implementation does not protect against bad hash functions.

Whether you need to grow the table when you add items or not is not relevant to the question because it is about lookup time.

ValueRange range = java.time.temporal.ValueRange.of(minValue, maxValue);
range.isValidIntValue(x);

it returns true if minValue <= x <= MaxValue - i.e within the range

it returns false if x < minValue or x > maxValue - i.e outofrange

Use with if condition as shown below:

int value = 10;
if(ValueRange.of(0, 100).isValidIntValue(value)) {
    System.out.println("Value is with in the Range.");
} else {
    System.out.println("Value is out of the Range.");
}

below program checks, if any of the passed integer value in the hasTeen method is within the range of 13(inclusive) to 19(Inclusive)

import java.time.temporal.ValueRange;    
public class TeenNumberChecker {

    public static void main(String[] args) {
        System.out.println(hasTeen(9, 99, 19));
        System.out.println(hasTeen(23, 15, 42));
        System.out.println(hasTeen(22, 23, 34));

    }

    public static boolean hasTeen(int firstNumber, int secondNumber, int thirdNumber) {

        ValueRange range = ValueRange.of(13, 19);
        System.out.println("*********Int validation Start ***********");
        System.out.println(range.isIntValue());
        System.out.println(range.isValidIntValue(firstNumber));
        System.out.println(range.isValidIntValue(secondNumber));
        System.out.println(range.isValidIntValue(thirdNumber));
        System.out.println(range.isValidValue(thirdNumber));
        System.out.println("**********Int validation End**************");

        if (range.isValidIntValue(firstNumber) || range.isValidIntValue(secondNumber) || range.isValidIntValue(thirdNumber)) {
            return true;
        } else
            return false;
    }
}

******OUTPUT******

true as 19 is part of range

true as 15 is part of range

false as all three value passed out of range

I have faced the same issue using Google Chrome browser. Same website was opening normally using the incognito mode and different browsers. At first, I cleared cached files and cookies over the past 24 hours, but this didn't help.

I realized that my first visit to the website was during the past 10 days. So, I cleared cached files and cookies over the past 4 weeks and that resolved the problem.
Note: I didn't clear my browsing history data

You can use following commands to extract public/private key from a PKCS#12 container:

• PKCS#1 Private key

  openssl pkcs12 -in yourP12File.pfx -nocerts -out privateKey.pem
  

• Certificates:

  openssl pkcs12 -in yourP12File.pfx -clcerts -nokeys -out publicCert.pem
  

For FC22 server

cd /etc/httpd/conf edit httpd.conf [enter]

Change: Listen 80 to: Listen whatevernumber

Save the file

systemctl restart httpd.service [enter] if required, open whatevernumber in your router / firewall

This is not the recommended way to solve this error but you can suppress it quickly, it will do the job . I prefer this for prototypes or demos . add

in Form1() constructor .

If this JSON file won't become too big over time, you should try:

1. Create a JavaScript object with the table array in it

   var obj = {
      table: []
   };
   

2. Add some data to it, for example:

   obj.table.push({id: 1, square:2});
   

3. Convert it from an object to a string with JSON.stringify

   var json = JSON.stringify(obj);
   

4. Use fs to write the file to disk

   var fs = require('fs');
   fs.writeFile('myjsonfile.json', json, 'utf8', callback);
   

5. If you want to append it, read the JSON file and convert it back to an object

   fs.readFile('myjsonfile.json', 'utf8', function readFileCallback(err, data){
       if (err){
           console.log(err);
       } else {
       obj = JSON.parse(data); //now it an object
       obj.table.push({id: 2, square:3}); //add some data
       json = JSON.stringify(obj); //convert it back to json
       fs.writeFile('myjsonfile.json', json, 'utf8', callback); // write it back 
   }});
   

This will work for data that is up to 100 MB effectively. Over this limit, you should use a database engine.

UPDATE:

Create a function which returns the current date (year+month+day) as a string. Create the file named this string + .json. the fs module has a function which can check for file existence named fs.stat(path, callback). With this, you can check if the file exists. If it exists, use the read function if it's not, use the create function. Use the date string as the path cuz the file will be named as the today date + .json. the callback will contain a stats object which will be null if the file does not exist.

I use following setenv.bat contents:

==============setenv.bat============

    set JAVA_OPTS=-XX:MaxPermSize=256m -Xms256M -Xmx768M -Xdebug -Xnoagent  -Xrunjdwp:transport=dt_socket,address=7777,server=y,suspend=n %JAVA_OPTS%

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

It also enables debugging and sets debug port to 7777, and appends previous content of JAVA_OPTS.

Do you want the JDK or the JRE? Anyways, I had this problem too, a few weeks ago. I followed the instructions here and it worked:

http://www.backtrack-linux.org/wiki/index.php/Java_Install

NOTE: Before installing Java make sure you kill Firefox.

root@bt:~# killall -9 /opt/firefox/firefox-bin

You can download java from the official website. (Download tar.gz version)

We first create the directory and place java there:

root@bt:~# mkdir /opt/java

root@bt:~# mv -f jre1.7.0_05/ /opt/java/

Final changes.

root@bt:~# update-alternatives --install /usr/bin/java java /opt/java/jre1.7.0_05/bin/java 1

root@bt:~# update-alternatives --set java /opt/java/jre1.7.0_05/bin/java

root@bt:~# export JAVA_HOME="/opt/java/jre1.7.0_05"

Adding the plugin to Firefox.

For Java 7 (32 bit)

root@bt:~# ln -sf $JAVA_HOME/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/

For Java 8 (64 bit)

root@bt:~# ln -sf $JAVA_HOME/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/

Testing the plugin.

root@bt:~# firefox http://java.com/en/download/testjava.jsp

You can get it with .outerHeight().

Sometimes, it will return 0. For the best results, you can call it in your div's ready event.

To be safe, you should not set the height of the div to x. You can keep its height auto to get content populated properly with the correct height.

$('#x').ready( function(){
// alerts the height in pixels
alert($('#x').outerHeight());
})

You can find a detailed post here.

Late to the party I know.

I use this:

public static string GetPropertyDisplayName(PropertyInfo pi)
{
  var dp = pi.GetCustomAttributes(typeof(DisplayNameAttribute), true).Cast<DisplayNameAttribute>().SingleOrDefault();
  return dp != null ? dp.DisplayName : pi.Name;
}

Hope this helps.

You can turn the axes off by following the advice in Veedrac's comment (linking to here) with one small modification.

Rather than using plt.axis('off') you should use ax.axis('off') where ax is a matplotlib.axes object. To do this for your code you simple need to add axarr[0,0].axis('off') and so on for each of your subplots.

The code below shows the result (I've removed the prune_matrix part because I don't have access to that function, in the future please submit fully working code.)

import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import matplotlib.cm as cm

img = mpimg.imread("stewie.jpg")

f, axarr = plt.subplots(2, 2)
axarr[0,0].imshow(img, cmap = cm.Greys_r)
axarr[0,0].set_title("Rank = 512")
axarr[0,0].axis('off')

axarr[0,1].imshow(img, cmap = cm.Greys_r)
axarr[0,1].set_title("Rank = %s" % 128)
axarr[0,1].axis('off')

axarr[1,0].imshow(img, cmap = cm.Greys_r)
axarr[1,0].set_title("Rank = %s" % 32)
axarr[1,0].axis('off')

axarr[1,1].imshow(img, cmap = cm.Greys_r)
axarr[1,1].set_title("Rank = %s" % 16)
axarr[1,1].axis('off')

plt.show()

Note: To turn off only the x or y axis you can use set_visible() e.g.:

axarr[0,0].xaxis.set_visible(False) # Hide only x axis

Split it apart and get the last element:

$end = end(explode('/', $url));
# or:
$end = array_slice(explode('/', $url), -1)[0];

Edit: To support apache-style-canonical URLs, rtrim is handy:

$end = end(explode('/', rtrim($url, '/')));
# or:
$end = array_slice(explode('/', rtrim($url, '/')), -1)[0];

A different example which might me considered more readable is (Demo):

$path = parse_url($url, PHP_URL_PATH);
$pathFragments = explode('/', $path);
$end = end($pathFragments);

This example also takes into account to only work on the path of the URL.

Yet another edit (years after), canonicalization and easy UTF-8 alternative use included (via PCRE regular expression in PHP):

<?php

use function call_user_func as f;
use UnexpectedValueException as e;

$url = 'http://example.com/artist/song/music-videos/song-title/9393903';

$result = preg_match('(([^/]*)/*$)', $url, $m)

    ? $m[1]
    : f(function() use ($url) {throw new e("pattern on '$url'");})
    ;

var_dump($result); # string(7) "9393903"

Which is pretty rough but shows how to wrap this this within a preg_match call for finer-grained control via PCRE regular expression pattern. To add some sense to this bare-metal example, it should be wrapped inside a function of its' own (which would also make the aliasing superfluous). Just presented this way for brevity.

A warning by which the compiler indicates that it cannot ensure type safety. The term "unchecked" warning is misleading. It does not mean that the warning is unchecked in any way. The term "unchecked" refers to the fact that the compiler and the runtime system do not have enough type information to perform all type checks that would be necessary to ensure type safety. In this sense, certain operations are "unchecked".

The most common source of "unchecked" warnings is the use of raw types. "unchecked" warnings are issued when an object is accessed through a raw type variable, because the raw type does not provide enough type information to perform all necessary type checks.

Example (of unchecked warning in conjunction with raw types):

TreeSet set = new TreeSet(); 
set.add("abc");        // unchecked warning 
set.remove("abc");

warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.TreeSet 
               set.add("abc");  
                      ^

When the add method is invoked the compiler does not know whether it is safe to add a String object to the collection. If the TreeSet is a collection that contains String s (or a supertype thereof), then it would be safe. But from the type information provided by the raw type TreeSet the compiler cannot tell. Hence the call is potentially unsafe and an "unchecked" warning is issued.

"unchecked" warnings are also reported when the compiler finds a cast whose target type is either a parameterized type or a type parameter.

Example (of an unchecked warning in conjunction with a cast to a parameterized type or type variable):

  class Wrapper<T> { 
  private T wrapped ; 
  public Wrapper (T arg) {wrapped = arg;} 
  ... 
  public Wrapper <T> clone() { 
    Wrapper<T> clon = null; 
     try {  
       clon = (Wrapper<T>) super.clone(); // unchecked warning 
     } catch (CloneNotSupportedException e) {  
       throw new InternalError();  
     } 
     try {  
       Class<?> clzz = this.wrapped.getClass(); 
       Method   meth = clzz.getMethod("clone", new Class[0]); 
       Object   dupl = meth.invoke(this.wrapped, new Object[0]); 
       clon.wrapped = (T) dupl; // unchecked warning 
     } catch (Exception e) {} 
     return clon; 
  } 
} 

warning: [unchecked] unchecked cast 
found   : java.lang.Object 
required: Wrapper <T> 
                  clon = ( Wrapper <T>)super.clone();  
                                                ^ 
warning: [unchecked] unchecked cast 
found   : java.lang.Object 
required: T 
                  clon. wrapped = (T)dupl;

A cast whose target type is either a (concrete or bounded wildcard) parameterized type or a type parameter is unsafe, if a dynamic type check at runtime is involved. At runtime, only the type erasure is available, not the exact static type that is visible in the source code. As a result, the runtime part of the cast is performed based on the type erasure, not on the exact static type.

In the example, the cast to Wrapper would check whether the object returned from super.clone is a Wrapper , not whether it is a wrapper with a particular type of members. Similarly, the casts to the type parameter T are cast to type Object at runtime, and probably optimized away altogether. Due to type erasure, the runtime system is unable to perform more useful type checks at runtime.

In a way, the source code is misleading, because it suggests that a cast to the respective target type is performed, while in fact the dynamic part of the cast only checks against the type erasure of the target type. The "unchecked" warning is issued to draw the programmer's attention to this mismatch between the static and dynamic aspect of the cast.

Please refer: What is an "unchecked" warning?

Check this fully functional directive for MEAN.JS (Angular.js, bootstrap, Express.js and MongoDb)

Based on @Blackhole ´s response, we just finished it to be used with mongodb and express.

It will allow you to save and load dates from a mongoose connector

Hope it Helps!!

angular.module('myApp')
.directive(
  'dateInput',
  function(dateFilter) {
    return {
      require: 'ngModel',
      template: '<input type="date" class="form-control"></input>',
      replace: true,
      link: function(scope, elm, attrs, ngModelCtrl) {
        ngModelCtrl.$formatters.unshift(function (modelValue) {
          return dateFilter(modelValue, 'yyyy-MM-dd');
        });

        ngModelCtrl.$parsers.push(function(modelValue){
           return angular.toJson(modelValue,true)
          .substring(1,angular.toJson(modelValue).length-1);
        })

      }
    };
  });

The JADE/HTML:

div(date-input, ng-model="modelDate")

    $.post("test.php", { 'choices[]': ["Jon", "Susan"] });

So I would just iterate over the checked boxes and build the array. Something like.

       var data = { 'user_ids[]' : []};
        $(":checked").each(function() {
       data['user_ids[]'].push($(this).val());
       });
        $.post("ajax.php", data);

Another way using map merge method

   Map<Character, Integer> map = new HashMap<>();
   String s = "aasjjikkk";
    for (int i = 0; i < s.length(); i++) {
        map.merge(s.charAt(i), 1, (l, r) -> l + r);

Try

echo -en "`date` User `whoami` started the script.\n" >> output.log

Try issuing this multiple times. I hope you are looking for the same output.

 ssh user@machine 'bash -s' < local_script.sh

or you can just

 ssh user@machine "remote command to run" 

Using parameter --force:

npm i -f

I know this is an older question, but for reference, a really simple way for formatting dates without any data annotations or any other settings is as follows:

@Html.TextBoxFor(m => m.StartDate, new { @Value = Model.StartDate.ToString("dd-MMM-yyyy") })

The above format can of course be changed to whatever.

So I was going to implement my own helper function, objLength(obj), which returns just Object(obj).keys.length. But then when I was adding it to my template *ngIf function, my IDE suggested objectKeys(). I tried it, and it worked. Following it to its declaration, it appears to be offered by lib.es5.d.ts, so there you go!

Here's how I implemented it (I have a custom object that uses server-side generated keys as an index for files I've uploaded):

        <div *ngIf="fileList !== undefined && objectKeys(fileList).length > 0">
          <h6>Attached Files</h6>
          <table cellpadding="0" cellspacing="0">
            <tr *ngFor="let file of fileList | keyvalue">
              <td><a href="#">{{file.value['fileName']}}</a></td>
              <td class="actions">
                <a title="Delete File" (click)="deleteAFile(file.key);">
                </a>
              </td>
            </tr>
          </table>
        </div>
