For some reason I was not able to use my scalar function until I referenced it using brackets, like so:

select [dbo].[fun_functional_score]('01091400003')

Another option is using eval. This is only suitable if the strings are trusted. The first script can echo the variable assignments:

echo "VAR=myvalue"

Then:

eval $(./first.sh) ./second.sh

This approach is of particular interest when the second script you want to set environment variables for is not in bash and you also don't want to export the variables, perhaps because they are sensitive and you don't want them to persist.

You can work with the overridable HandleUnauthorizedRequest inside your custom AuthorizeAttribute

Like this:

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
    // Returns HTTP 401 by default - see HttpUnauthorizedResult.cs.
    filterContext.Result = new RedirectToRouteResult(
    new RouteValueDictionary 
    {
        { "action", "YourActionName" },
        { "controller", "YourControllerName" },
        { "parameterName", "YourParameterValue" }
    });
}

You can also do something like this:

private class RedirectController : Controller
{
    public ActionResult RedirectToSomewhere()
    {
        return RedirectToAction("Action", "Controller");
    }
}

Now you can use it in your HandleUnauthorizedRequest method this way:

filterContext.Result = (new RedirectController()).RedirectToSomewhere();

This is an example that could work for you if what you need is not exactly the path, but a reference to the file working offline.

You can achieve that by using positioning.

Try

position: absolute;

to get the 100% height.

Here's a very easy way without having to deal with the ABC module.

In the __init__ method of the class that you want to be an abstract class, you can check the "type" of self. If the type of self is the base class, then the caller is trying to instantiate the base class, so raise an exception. Here's a simple example:

class Base():
    def __init__(self):
        if type(self) is Base:
            raise Exception('Base is an abstract class and cannot be instantiated directly')
        # Any initialization code
        print('In the __init__  method of the Base class')

class Sub(Base):
    def __init__(self):
        print('In the __init__ method of the Sub class before calling __init__ of the Base class')
        super().__init__()
        print('In the __init__ method of the Sub class after calling __init__ of the Base class')

subObj = Sub()
baseObj = Base()

When run, it produces:

In the __init__ method of the Sub class before calling __init__ of the Base class
In the __init__  method of the Base class
In the __init__ method of the Sub class after calling __init__ of the Base class
Traceback (most recent call last):
  File "/Users/irvkalb/Desktop/Demo files/Abstract.py", line 16, in <module>
    baseObj = Base()
  File "/Users/irvkalb/Desktop/Demo files/Abstract.py", line 4, in __init__
    raise Exception('Base is an abstract class and cannot be instantiated directly')
Exception: Base is an abstract class and cannot be instantiated directly

This shows that you can instantiate a subclass that inherits from a base class, but you cannot instantiate the base class directly.

Though asynchronous style may be the nature of node.js and generally you should not do this, there are some times you want to do this.

I'm writing a handy script to check an API and want not to mess it up with callbacks.

Javascript cannot execute synchronous requests, but C libraries can.

You should look at the source of the HashSet constructor it calls... it's a special constructor that makes the backing Map a LinkedHashMap instead of just a HashMap.

There are three ways of defining things in Scala:

• def defines a method
• val defines a fixed value (which cannot be modified)
• var defines a variable (which can be modified)

Looking at your code:

def person = new Person("Kumar",12)

This defines a new method called person. You can call this method only without () because it is defined as parameterless method. For empty-paren method, you can call it with or without '()'. If you simply write:

person

then you are calling this method (and if you don't assign the return value, it will just be discarded). In this line of code:

person.age = 20

what happens is that you first call the person method, and on the return value (an instance of class Person) you are changing the age member variable.

And the last line:

println(person.age)

Here you are again calling the person method, which returns a new instance of class Person (with age set to 12). It's the same as this:

println(person().age)

The mysql_install_db script also needs the datadir parameter:

mysql_install_db --user=root --datadir=$db_datapath

On Maria DB you use the install script mysql_install_db to install and initialize. In my case I use an environment variable for the data path. Not only does mysqld need to know where the data is (specified via commandline), but so does the install script.

Here's the easy way to get access to the web.config settings anywhere in your C# project.

 Properties.Settings.Default

Use case:

litBodyText.Text = Properties.Settings.Default.BodyText;
litFootText.Text = Properties.Settings.Default.FooterText;
litHeadText.Text = Properties.Settings.Default.HeaderText;

Web.config file:

  <applicationSettings>
    <myWebSite.Properties.Settings> 
      <setting name="BodyText" serializeAs="String">
        <value>
          &lt;h1&gt;Hello World&lt;/h1&gt;
          &lt;p&gt;
      Ipsum Lorem
          &lt;/p&gt;
        </value>
      </setting>
      <setting name="HeaderText" serializeAs="String">
      My header text
        <value />
      </setting>
      <setting name="FooterText" serializeAs="String">
      My footer text
        <value />
      </setting>
    </myWebSite.Properties.Settings>
  </applicationSettings>

No need for special routines - everything is right there already. I'm surprised that no one has this answer for the best way to read settings from your web.config file.

grep -A 10 <Pattern>

This is to grab the pattern and the next 10 lines after the pattern. This would work well only for a known pattern, if you don't have a known pattern use the "head" suggestions.

PsSuspend command line utility from SysInternals suite. It suspends / resumes a process by its id.

I think it's better to use importlib.import_module('.c', __name__) since you don't need to know about a and b.

I'm also wondering that, if you have to use importlib.import_module('a.b.c'), why not just use import a.b.c?

When you

import App from './App.jsx';

That means it will import whatever you export default. You can rename App class inside App.jsx to whatever you want as long as you export default it will work but you can only have one export default.

So you only need to export default App and you don't need to export the rest.

If you still want to export the rest of the components, you will need named export.

https://developer.mozilla.org/en/docs/web/javascript/reference/statements/export

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

set -x is fine.

Another way to print each executed command is to use trap with DEBUG. Put this line at the beginning of your script :

trap 'echo "# $BASH_COMMAND"' DEBUG

You can find a lot of other trap usages here.

I created a function that might help. All it does is imitate the alert but put an image instead of text.

function alertImage(imgsrc) {
$('.d').css({
    'position': 'absolute',
    'top': '0',
    'left': '50%',
    '-webkit-transform': 'translate(-50%, 0)'
});
$('.d').animate({
    opacity: 0
}, 0)
$('.d').animate({
    opacity: 1,
    top: "10px"
}, 250)
$('.d').append('An embedded page on this page says')
$('.d').append('<br><img src="' + imgsrc + '">')
$('.b').css({
  'position':'absolute',
  '-webkit-transform': 'translate(-100%, -100%)',
  'top':'100%',
  'left':'100%',
  'display':'inline',
  'background-color':'#598cbd',
  'border-radius':'4px',
  'color':'white',
  'border':'none',
  'width':'66',
  'height':'33'
})
}

<script type="text/javascript" src="https://code.jquery.com/jquery-latest.min.js"></script>
<div class="d"><button onclick="$('.d').html('')" class="b">OK</button></div>

.d{
font-size: 17px;
  font-family: sans-serif;
}
.b{
  display: none;
}

A different case in which I encountered this was when I was using echo to pipe the JSON into my python script and carelessly wrapped the JSON string in double quotes:

echo "{"thumbnailWidth": 640}" | myscript.py

Note that the JSON string itself has quotes and I should have done:

echo '{"thumbnailWidth": 640}' | myscript.py

As it was, this is what the python script received: {thumbnailWidth: 640}; the double quotes were effectively stripped.

Does this not work?

$conn=new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
    // If this is your connection then you have to assign null
    // to your connection variable as follows:
$conn=null;
    // By this way you can close connection in PDO.

We should first read the documentation on proxy_pass carefully and fully.

The URI passed to upstream server is determined based on whether "proxy_pass" directive is used with URI or not. Trailing slash in proxy_pass directive means that URI is present and equal to /. Absense of trailing slash means hat URI is absent.

Proxy_pass with URI:

location /some_dir/ {
    proxy_pass http://some_server/;
}

With the above, there's the following proxy:

http:// your_server/some_dir/ some_subdir/some_file ->
http:// some_server/          some_subdir/some_file

Basically, /some_dir/ gets replaced by / to change the request path from /some_dir/some_subdir/some_file to /some_subdir/some_file.

Proxy_pass without URI:

location /some_dir/ {
    proxy_pass http://some_server;
}

With the second (no trailing slash): the proxy goes like this:

http:// your_server /some_dir/some_subdir/some_file ->
http:// some_server /some_dir/some_subdir/some_file

Basically, the full original request path gets passed on without changes.

So, in your case, it seems you should just drop the trailing slash to get what you want.

Caveat

Note that automatic rewrite only works if you don't use variables in proxy_pass. If you use variables, you should do rewrite yourself:

location /some_dir/ {
  rewrite    /some_dir/(.*) /$1 break;
  proxy_pass $upstream_server;
}

There are other cases where rewrite wouldn't work, that's why reading documentation is a must.

Edit

Reading your question again, it seems I may have missed that you just want to edit the html output.

For that, you can use the sub_filter directive. Something like ...

location /admin/ {
    proxy_pass http://localhost:8080/;
    sub_filter "http://your_server/" "http://your_server/admin/";
    sub_filter_once off;
}

Basically, the string you want to replace and the replacement string

Here is my way to do it by using a UICollectionViewFlowLayout to override the targetContentOffset:

(Although in the end, I end up not using this and use UIPageViewController instead.)

/**
 A UICollectionViewFlowLayout with...
 - paged horizontal scrolling
 - itemSize is the same as the collectionView bounds.size
 */
class PagedFlowLayout: UICollectionViewFlowLayout {

  override init() {
    super.init()
    self.scrollDirection = .horizontal
    self.minimumLineSpacing = 8 // line spacing is the horizontal spacing in horizontal scrollDirection
    self.minimumInteritemSpacing = 0
    if #available(iOS 11.0, *) {
      self.sectionInsetReference = .fromSafeArea // for iPhone X
    }
  }

  required init?(coder aDecoder: NSCoder) {
    fatalError("not implemented")
  }

  // Note: Setting `minimumInteritemSpacing` here will be too late. Don't do it here.
  override func prepare() {
    super.prepare()
    guard let collectionView = collectionView else { return }
    collectionView.decelerationRate = UIScrollViewDecelerationRateFast // mostly you want it fast!

    let insetedBounds = UIEdgeInsetsInsetRect(collectionView.bounds, self.sectionInset)
    self.itemSize = insetedBounds.size
  }

  // Table: Possible cases of targetContentOffset calculation
  // -------------------------
  // start |          |
  // near  | velocity | end

  // -------------------------
  //   0   | forward  |  1
  //   0   | still    |  0
  //   0   | backward |  0
  //   1   | forward  |  1
  //   1   | still    |  1
  //   1   | backward |  0
  // -------------------------
  override func targetContentOffset( //swiftlint:disable:this cyclomatic_complexity
    forProposedContentOffset proposedContentOffset: CGPoint, withScrollingVelocity velocity: CGPoint) -> CGPoint {

    guard let collectionView = collectionView else { return proposedContentOffset }

    let pageWidth = itemSize.width + minimumLineSpacing
    let currentPage: CGFloat = collectionView.contentOffset.x / pageWidth
    let nearestPage: CGFloat = round(currentPage)
    let isNearPreviousPage = nearestPage < currentPage

    var pageDiff: CGFloat = 0
    let velocityThreshold: CGFloat = 0.5 // can customize this threshold
    if isNearPreviousPage {
      if velocity.x > velocityThreshold {
        pageDiff = 1
      }
    } else {
      if velocity.x < -velocityThreshold {
        pageDiff = -1
      }
    }

    let x = (nearestPage + pageDiff) * pageWidth
    let cappedX = max(0, x) // cap to avoid targeting beyond content
    //print("x:", x, "velocity:", velocity)
    return CGPoint(x: cappedX, y: proposedContentOffset.y)
  }

}

Abstraction

In Java, abstraction means hiding the information to the real world. It establishes the contract between the party to tell about “what should we do to make use of the service”.

Example, In API development, only abstracted information of the service has been revealed to the world rather the actual implementation. Interface in java can help achieve this concept very well.

Interface provides contract between the parties, example, producer and consumer. Producer produces the goods without letting know the consumer how the product is being made. But, through interface, Producer let all consumer know what product can buy. With the help of abstraction, producer can markets the product to their consumers.

Encapsulation:

Encapsulation is one level down of abstraction. Same product company try shielding information from each other production group. Example, if a company produce wine and chocolate, encapsulation helps shielding information how each product Is being made from each other.

1. If I have individual package one for wine and another one for chocolate, and if all the classes are declared in the package as default access modifier, we are giving package level encapsulation for all classes.
2. Within a package, if we declare each class filed (member field) as private and having a public method to access those fields, this way giving class level encapsulation to those fields

I use freeware called "GS Timer".

Just make a batch file like this:

timer
yourapp.exe
timer /s

If you need a set of times, just pipe the output of timer /s into a .txt file.

The resolution is 0.1 seconds.

What you're trying to do is essentially to find a path between two vertices in a (directed?) graph check out Dijkstra's algorithm if you need shortest path or write a simple recursive function if you need whatever paths exist.

just follow three steps, git branch problem will be solved.

git remote update
git fetch
git checkout --track origin/test-branch

xcopy "your-source-path" "your-destination-path" /D /y /s /r /exclude:path-to-txt- file\ExcludedFilesList.txt

Notice the quotes in source path and destination path, but not in path to exludelist txt file.

Content of ExcludedFilesList.txt is the following: .cs\

I'm using this command to copy file from one project in my solution, to another and excluding .cs files.

/D Copy only files that are modified in sourcepath
/y Suppresses prompting to confirm you want to overwrite an existing destination file.
/s Copies directories and subdirectories except empty ones.
/r Overwrites read-only files.

First of all, do you really need to store indices like this? Have you looked into std::map, enabling you to store key => value pairs?

Secondly, if you used iterators instead, you would be able to return std::vector.end() to indicate an invalid result. To convert an iterator to an index you simply use

size_t i = it - myvector.begin();

Expanding on patszim's answer for those in a rush.

1. Open Excel workbook.
2. Alt+F11 to open VBA/Macros window.
3. Add reference to regex under Tools then References
   
4. and selecting Microsoft VBScript Regular Expression 5.5
   
5. Insert a new module (code needs to reside in the module otherwise it doesn't work).
   
6. In the newly inserted module,
   

7. add the following code:

   Function RegxFunc(strInput As String, regexPattern As String) As String
       Dim regEx As New RegExp
       With regEx
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
           .pattern = regexPattern
       End With
   
       If regEx.Test(strInput) Then
           Set matches = regEx.Execute(strInput)
           RegxFunc = matches(0).Value
       Else
           RegxFunc = "not matched"
       End If
   End Function
   

8. The regex pattern is placed in one of the cells and absolute referencing is used on it. Function will be tied to workbook that its created in.
   If there's a need for it to be used in different workbooks, store the function in Personal.XLSB

I wouldn't use Thread.Sleep(). Either use a scheduled task (as others have mentioned), or set up a timer inside your service, which fires periodically (every 10 minutes for example) and check if the date changed since the last run:

private Timer _timer;
private DateTime _lastRun = DateTime.Now.AddDays(-1);

protected override void OnStart(string[] args)
{
    _timer = new Timer(10 * 60 * 1000); // every 10 minutes
    _timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
    _timer.Start();
    //...
}


private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    // ignore the time, just compare the date
    if (_lastRun.Date < DateTime.Now.Date)
    {
        // stop the timer while we are running the cleanup task
        _timer.Stop();
        //
        // do cleanup stuff
        //
        _lastRun = DateTime.Now;
        _timer.Start();
    }
}

You can use http://pingdom.com/ to check your app; if done every minute or so, heroku won't idle your app and won't need to spin-up.

There is the option to use OleDB and use the Excel sheets like datatables in a database...

Just an example.....

string con =
  @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\temp\test.xls;" + 
  @"Extended Properties='Excel 8.0;HDR=Yes;'";    
using(OleDbConnection connection = new OleDbConnection(con))
{
    connection.Open();
    OleDbCommand command = new OleDbCommand("select * from [Sheet1$]", connection); 
    using(OleDbDataReader dr = command.ExecuteReader())
    {
         while(dr.Read())
         {
             var row1Col0 = dr[0];
             Console.WriteLine(row1Col0);
         }
    }
}

This example use the Microsoft.Jet.OleDb.4.0 provider to open and read the Excel file. However, if the file is of type xlsx (from Excel 2007 and later), then you need to download the Microsoft Access Database Engine components and install it on the target machine.

The provider is called Microsoft.ACE.OLEDB.12.0;. Pay attention to the fact that there are two versions of this component, one for 32bit and one for 64bit. Choose the appropriate one for the bitness of your application and what Office version is installed (if any). There are a lot of quirks to have that driver correctly working for your application. See this question for example.

Of course you don't need Office installed on the target machine.

While this approach has some merits, I think you should pay particular attention to the link signaled by a comment in your question Reading excel files from C#. There are some problems regarding the correct interpretation of the data types and when the length of data, present in a single excel cell, is longer than 255 characters

You can use any of these:

# Create a range that does not contain 50
for i in [x for x in xrange(100) if x != 50]:
    print i

# Create 2 ranges [0,49] and [51, 100] (Python 2)
for i in range(50) + range(51, 100):
    print i

# Create a iterator and skip 50
xr = iter(xrange(100))
for i in xr:
    print i
    if i == 49:
        next(xr)

# Simply continue in the loop if the number is 50
for i in range(100):
    if i == 50:
        continue
    print i

A different answer if you need to save the output of your whole scrollback buffer from an already actively running screen:

Ctrl-a [ g SPACE G $ >.

This will save your whole buffer to /tmp/screen-exchange

For creating new Activity simply click ctrl+N one window is appear select android then another window is appear give name to that Secondary Activity.Now another Activity is created

You can use the inbuilt function max() with multiple arguments:

print max(1, 2, 3)

or a list:

list = [1, 2, 3]
print max(list)

or in fact anything iterable.

grep -a will force grep to search and output from a file that grep thinks is binary. grep -a re test.log

Is this what you are looking for?

If you just happen to have a Map with Integer keys you cannot change, you could write a custom EL function to convert a Long to Integer. This would allow you to do something like:

<c:out value="${map[myLib:longToInteger(1)]}"/>

Run this command:

select @@version

For those who want a summary,

android:minSdkVersion

is minimum version till your application supports. If your device has lower version of android , app will not install.

while,

android:targetSdkVersion

is the API level till which your app is designed to run. Means, your phone's system don't need to use any compatibility behaviours to maintain forward compatibility because you have tested against till this API.

Your app will still run on Android versions higher than given targetSdkVersion but android compatibility behaviour will kick in.

Freebie -

android:maxSdkVersion

if your device's API version is higher, app will not install. Ie. this is the max API till which you allow your app to install.

ie. for MinSDK -4, maxSDK - 8, targetSDK - 8 My app will work on minimum 1.6 but I also have used features that are supported only in 2.2 which will be visible if it is installed on a 2.2 device. Also, for maxSDK - 8, this app will not install on phones using API > 8.

At the time of writing this answer, Android documentation was not doing a great job at explaining it. Now it is very well explained. Check it here

Please read the example in rfc6749 sec 7.1 first.

The bearer token is a type of access token, which does NOT require PoP(proof-of-possession) mechanism.

PoP means kind of multi-factor authentication to make access token more secure. ref

Proof-of-Possession refers to Cryptographic methods that mitigate the risk of Security Tokens being stolen and used by an attacker. In contrast to 'Bearer Tokens', where mere possession of the Security Token allows the attacker to use it, a PoP Security Token cannot be so easily used - the attacker MUST have both the token itself and access to some key associated with the token (which is why they are sometimes referred to 'Holder-of-Key' (HoK) tokens).

Maybe it's not the case, but I would say,

• access token = payment methods
• bearer token = cash
• access token with PoP mechanism = credit card (signature or password will be verified, sometimes need to show your ID to match the name on the card)

BTW, there's a draft of "OAuth 2.0 Proof-of-Possession (PoP) Security Architecture" now.

Normally when you don't use __block, the block will copy(retain) the variable, so even if you modify the variable, the block has access to the old object.

NSString* str = @"hello";
void (^theBlock)() = ^void() {
    NSLog(@"%@", str);
};
str = @"how are you";
theBlock(); //prints @"hello"

In these 2 cases you need __block:

1.If you want to modify the variable inside the block and expect it to be visible outside:

__block NSString* str = @"hello";
void (^theBlock)() = ^void() {
    str = @"how are you";
};
theBlock();
NSLog(@"%@", str); //prints "how are you"

2.If you want to modify the variable after you have declared the block and you expect the block to see the change:

__block NSString* str = @"hello";
void (^theBlock)() = ^void() {
    NSLog(@"%@", str);
};
str = @"how are you";
theBlock(); //prints "how are you"

The object-fit property provides a non-hackish way for doing this (with image centered). It has been supported in major browsers for a few years now (Chrome/Safari since 2013, Firefox since 2015, and Edge since 2015) with the exception of Internet Explorer.

img.rounded {_x000D_
  object-fit: cover;_x000D_
  border-radius: 50%;_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_

Add any other allowable non-alphanumeric characters to the middle brackets to allow them to be parsed as well.

It's called the 'ternary' or 'conditional' operator.

Example

The ?: operator can be used as a shortcut for an if...else statement. It is typically used as part of a larger expression where an if...else statement would be awkward. For example:

var now = new Date();
var greeting = "Good" + ((now.getHours() > 17) ? " evening." : " day.");

The example creates a string containing "Good evening." if it is after 6pm. The equivalent code using an if...else statement would look as follows:

var now = new Date();
var greeting = "Good";
if (now.getHours() > 17)
   greeting += " evening.";
else
   greeting += " day.";

From MSDN JS documentation.

Basically it's a shorthand conditional statement.

Also see:

• Operator precedence with Javascript Ternary operator
• Wikipedia

Try this....

var d = new Date();
alert(d.getFullYear()+'/'+(d.getMonth()+1)+'/'+d.getDate());

getMonth() return month 0 to 11 so we would like to add 1 for accurate month

You might want to try Catel. It allows you to define a DataWindow class (instead of Window), and that class automatically creates the view model for you. This way, you can use the declaration of the ViewModel as you did in your original post, and the view model will still be created and set as DataContext.

See this article for an example.

You can do it by RENAME statement for each table in your "current_db" after create the new schema "other_db"

RENAME TABLE current_db.tbl_name TO other_db.tbl_name

Source Rename Table Syntax

This should work:

import java.util.Scanner;

public class Test {
    public static void main(String... args) throws Throwable {
        Scanner kb = new Scanner(System.in);

        int num1;
        System.out.print("Enter number 1: ");
        while (true)
            try {
                num1 = Integer.parseInt(kb.nextLine());
                break;
            } catch (NumberFormatException nfe) {
                System.out.print("Try again: ");
            }

        int num2;
        do {
            System.out.print("Enter number 2: ");
            while (true)
                try {
                    num2 = Integer.parseInt(kb.nextLine());
                    break;
                } catch (NumberFormatException nfe) {
                    System.out.print("Try again: ");
                }
        } while (num2 < num1);

    }
}

int* test();

but it would be "more C++" to use vectors:

std::vector< int > test();

EDIT
I'll clarify some point. Since you mentioned C++, I'll go with new[] and delete[] operators, but it's the same with malloc/free.

In the first case, you'll write something like:

int* test() {
    return new int[size_needed];
}

but it's not a nice idea because your function's client doesn't really know the size of the array you are returning, although the client can safely deallocate it with a call to delete[].

int* theArray = test();
for (size_t i; i < ???; ++i) { // I don't know what is the array size!
    // ...
}
delete[] theArray; // ok.

A better signature would be this one:

int* test(size_t& arraySize) {
    array_size = 10;
    return new int[array_size];
}

And your client code would now be:

size_t theSize = 0;
int* theArray = test(theSize);
for (size_t i; i < theSize; ++i) { // now I can safely iterate the array
    // ...
}
delete[] theArray; // still ok.

Since this is C++, std::vector<T> is a widely-used solution:

std::vector<int> test() {
    std::vector<int> vector(10);
    return vector;
}

Now you don't have to call delete[], since it will be handled by the object, and you can safely iterate it with:

std::vector<int> v = test();
std::vector<int>::iterator it = v.begin();
for (; it != v.end(); ++it) {
   // do your things
}

which is easier and safer.

Might very well be the Console.ReadLine blocking your callback's Console.Writeline, in fact. The sample on MSDN looks ALMOST identical, except they use ReadKey (which doesn't lock the console).

What about this:

isset($arr['key1'], $arr['key2']) 

only return true if both are not null

if is null, key is not in array

This could be complicated way of doing

String newString = new String(oldString);

This shortens the String is the underlying char[] used is much longer.

However more specifically it will be checking that every character can be UTF-8 encoded.

There are some "characters" you can have in a String which cannot be encoded and these would be turned into ?

Any character between \uD800 and \uDFFF cannot be encoded and will be turned into '?'

String oldString = "\uD800";
String newString = new String(oldString.getBytes("UTF-8"), "UTF-8");
System.out.println(newString.equals(oldString));

prints

false

You can get any part of the file path using the FileSystemObject. GetFileName(filepath) gives you what you want.

Modified code below:

Sub GetFilePath()
Dim objFSO as New FileSystemObject

Set myFile = Application.FileDialog(msoFileDialogOpen)
With myFile
.Title = "Choose File"
.AllowMultiSelect = False
If .Show <> -1 Then
Exit Sub
End If
FileSelected = .SelectedItems(1)
End With

ActiveSheet.Range("A1") = FileSelected 'The file path
ActiveSheet.Range("A2") = objFSO.GetFileName(FileSelected) 'The file name
End Sub

To answer your question, yes it does: your synchronized method cannot be executed by more than one thread at a time.

I had a similar issue. In eclipse I compared my project with a sample project which is working fine (generated by a maven archetype). I found my project has missed 2 lines in /.classpath file. I copied those 2 lines and it fixed the issue. It seems even though I set build path in project preferences, eclipse has not updated accordingly for some reasons.

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" output="target/classes" path="src/main/java"/>
    <classpathentry kind="src" output="target/test-classes" path="src/test/java"/>
    ...
</classpath>

For simplicities sake, you can use:

(.*)\s(.*)

The thing I like about this is that the last name is always after the first name, so if you're going to enter this matched groups into a database, and the name is John M. Smith, the 1st group will be John M., and the 2nd group will be Smith.

The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();

names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

or just read the line and parse the value as an Integer.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());

names = new String[nnames];
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

I am on IntelliJ and faced the same issue. Below is how i resolved it:

1. Added the resource import as following in Spring application class along with other imports: @ImportResource("applicationContext.xml")

2. Saw IDE showing : Cannot resolve file 'applicationContext.xml' and also suggesting paths where its expecting the file (It was not the resources where the file applicationContext.xml was originally kept)

3. Copied the file at the expected location and the Exception got resolved.

Screen shot below for easy ref:

But if you would like to keep it at resources then follow this great answer link below and add the resources path so that it gets searched. With this setting exception resolves without @ImportResource described in above steps:

https://stackoverflow.com/a/24843914/5916535

Use:

string str = "Hello";
char[] characters = str.ToCharArray();

If you have a single character string, You can also try

string str = "A";
char character = char.Parse(str);    

//OR 
string str = "A";
char character = str.ToCharArray()[0];

If the file is on your local domain, you don't need to put the full URL. Only the path to the file. If the file is in a different directory, then you need to preface the path with "."

$file = './images/image.jpg';
if (file_exists($file)) {}

Often times the "." is left off which will cause the file to be shown as not existing, when it in fact does.

Use the UNC path rather than HTTP. This code works:

Public Sub ListFiles()
    Dim folder As folder
    Dim f As File
    Dim fs As New FileSystemObject
    Dim RowCtr As Integer

    RowCtr = 1
    Set folder = fs.GetFolder("\\SharePointServer\Path\MorePath\DocumentLibrary\Folder")
    For Each f In folder.Files
       Cells(RowCtr, 1).Value = f.Name
       RowCtr = RowCtr + 1
    Next f
End Sub

To get the UNC path to use, go into the folder in the document library, drop down the Actions menu and choose Open in Windows Explorer. Copy the path you see there and use that.

Boost Filesystem's initial_path() behaves like POSIX's getcwd(), and neither does what you want by itself, but appending argv[0] to either of them should do it.

You may note that the result is not always pretty--you may get things like /foo/bar/../../baz/a.out or /foo/bar//baz/a.out, but I believe that it always results in a valid path which names the executable (note that consecutive slashes in a path are collapsed to one).

I previously wrote a solution using envp (the third argument to main() which worked on Linux but didn't seem workable on Windows, so I'm essentially recommending the same solution as someone else did previously, but with the additional explanation of why it is actually correct even if the results are not pretty.

As has been mentioned, as of PHP 5.6+ you can (should!) use the ... token (aka "splat operator", part of the variadic functions functionality) to easily call a function with an array of arguments:

<?php
function variadic($arg1, $arg2)
{
    // Do stuff
    echo $arg1.' '.$arg2;
}

$array = ['Hello', 'World'];

// 'Splat' the $array in the function call
variadic(...$array);

// 'Hello World'

Note: array items are mapped to arguments by their position in the array, not their keys.

As per CarlosCarucce's comment, this form of argument unpacking is the fastest method by far in all cases. In some comparisons, it's over 5x faster than call_user_func_array.

Aside

Because I think this is really useful (though not directly related to the question): you can type-hint the splat operator parameter in your function definition to make sure all of the passed values match a specific type.

(Just remember that doing this it MUST be the last parameter you define and that it bundles all parameters passed to the function into the array.)

This is great for making sure an array contains items of a specific type:

<?php

// Define the function...

function variadic($var, SomeClass ...$items)
{
    // $items will be an array of objects of type `SomeClass`
}

// Then you can call...

variadic('Hello', new SomeClass, new SomeClass);

// or even splat both ways

$items = [
    new SomeClass,
    new SomeClass,
];

variadic('Hello', ...$items);

this work for me:

SEARCH:^\r  
REPLACE:            (empty)

If this happens in visual studio then clean your project and run it again.

The purpose of this answer is not to add anything new that the others don't already cover, but to extend @Kevin Loney's answer.

You could use the lightweight declaration:

int *ary = new int[SizeX*SizeY]

and access syntax will be:

ary[i*SizeY+j]     // ary[i][j]

but this is cumbersome for most, and can lead to confusion. So, you can define a macro as follows:

#define ary(i, j)   ary[(i)*SizeY + (j)]

Now you can access the array using the very similar syntax ary(i, j) // means ary[i][j]. This has the advantages of being simple and beautiful, and at the same time, using expressions in place of the indices is also simpler and less confusing.

To access, say, ary[2+5][3+8], you can write ary(2+5, 3+8) instead of the complex-looking ary[(2+5)*SizeY + (3+8)] i.e. it saves parentheses and helps readability.

Caveats:

• Although the syntax is very similar, it is NOT the same.
• In case you pass the array to other functions, SizeY has to be passed with the same name (or instead be declared as a global variable).

Or, if you need to use the array in multiple functions, then you could add SizeY also as another parameter in the macro definition like so:

#define ary(i, j, SizeY)  ary[(i)*(SizeY)+(j)]

You get the idea. Of course, this becomes too long to be useful, but it can still prevent the confusion of + and *.

This is not recommended definitely, and it will be condemned as bad practice by most experienced users, but I couldn't resist sharing it because of its elegance.

Edit:
If you want a portable solution that works for any number of arrays, you can use this syntax:

#define access(ar, i, j, SizeY) ar[(i)*(SizeY)+(j)]

and then you can pass on any array to the call, with any size using the access syntax:

access(ary, i, j, SizeY)      // ary[i][j]

P.S.: I've tested these, and the same syntax works (as both an lvalue and an rvalue) on g++14 and g++11 compilers.

You can use the files from debug folder,however if you look at app debug informations with some inspection software,you can clearly see "Symbols File Name" which can reveals not wanted informations in path to the original exe file.

componentDidUpdate(prevProps){ 

    if (this.state.authToken==null&&prevProps.authToken==null) {

          AccountKit.getCurrentAccount().then(account => {
            this.setState({
              authToken: token,
              loggedAccount: account
            });
          });

Note: Once it happened that I accidentally had a space before my database name such as mydatabase instead of mydatabase, phpmyadmin won't show the space, but if you run it from the command line interface of mysql, such as mysql -u the_user -p then show databases, you'll be able to see the space.

One simple thing you could do is abstract the test inside a function.

local function isempty(s)
  return s == nil or s == ''
end

if isempty(foo) then
  foo = "default value"
end

If you are truly comparing date only with no time component, another solution that may feel wrong but works and avoids all Date() time and timezone headaches is to compare the ISO string date directly using string comparison:

> "2019-04-22" <= "2019-04-23"
true
> "2019-04-22" <= "2019-04-22"
true
> "2019-04-22" <= "2019-04-21"
false
> "2019-04-22" === "2019-04-22"
true

You can get the current date (UTC date, not neccesarily the user's local date) using:

> new Date().toISOString().split("T")[0]
"2019-04-22"

My argument in favor of it is programmer simplicity -- you're much less likely to botch this than trying to handle datetimes and offsets correctly, probably at the cost of speed (I haven't compared performance)

Several ways to achieve this. Examples are as below

a. return "22".toInteger()
b. if("22".isInteger()) return "22".toInteger()
c. return "22" as Integer()
d. return Integer.parseInt("22")

Hope this helps

The way to output > character is to prepend it with ^ escape character:

echo ^>

will print simply

You can use this code without arrows.....i.e by clicking on header it automatically shows ascending and descending order of elements

Since other solutions are old and either poorly-working or not working at all, I've modified NestedScrollView, which is stable, modern and it has all you expect from a scroll view. Except for horizontal scrolling.

Here's the repo: https://github.com/ultimate-deej/TwoWayNestedScrollView

I've made no changes, no "improvements" to the original NestedScrollView expect for what was absolutely necessary. The code is based on androidx.core:core:1.3.0, which is the latest stable version at the time of writing.

All of the following works:

• Lift on scroll (since it's basically a NestedScrollView)
• Edge effects in both dimensions
• Fill viewport in both dimensions

You can write integer in xml file also..
have you seen [this] http://developer.android.com/guide/topics/resources/more-resources.html#Integer ? use as .

 context.getResources().getInteger(R.integer.height_pop);

Eager Loading: Eager Loading helps you to load all your needed entities at once. i.e. related objects (child objects) are loaded automatically with its parent object.

When to use:

1. Use Eager Loading when the relations are not too much. Thus, Eager Loading is a good practice to reduce further queries on the Server.
2. Use Eager Loading when you are sure that you will be using related entities with the main entity everywhere.

Lazy Loading: In case of lazy loading, related objects (child objects) are not loaded automatically with its parent object until they are requested. By default LINQ supports lazy loading.

When to use:

1. Use Lazy Loading when you are using one-to-many collections.
2. Use Lazy Loading when you are sure that you are not using related entities instantly.

NOTE: Entity Framework supports three ways to load related data - eager loading, lazy loading and explicit loading.

There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

It's worth pointing out that this advice is for CakePHP 2.x, not 3.x.

The CakePHP Way

You would create a relationship with your User model and Messages Model, and use the containable behavior:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array('Message');
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array('User');
}

You need to change the messages.from column to be messages.user_id so that cake can automagically associate the records for you.

Then you can do this from the messages controller:

$this->Message->find('all', array(
    'contain' => array('User')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The (other) CakePHP way

I recommend using the first method, because it will save you a lot of time and work. The first method also does the groundwork of setting up a relationship which can be used for any number of other find calls and conditions besides the one you need now. However, cakePHP does support a syntax for defining your own joins. It would be done like this, from the MessagesController:

$this->Message->find('all', array(
    'joins' => array(
        array(
            'table' => 'users',
            'alias' => 'UserJoin',
            'type' => 'INNER',
            'conditions' => array(
                'UserJoin.id = Message.from'
            )
        )
    ),
    'conditions' => array(
        'Message.to' => 4
    ),
    'fields' => array('UserJoin.*', 'Message.*'),
    'order' => 'Message.datetime DESC'
));

Note, I've left the field name messages.from the same as your current table in this example.

Using two relationships to the same model

Here is how you can do the first example using two relationships to the same model:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array(
        'MessagesSent' => array(
            'className'  => 'Message',
            'foreignKey' => 'from'
         )
    );
    public $belongsTo = array(
        'MessagesReceived' => array(
            'className'  => 'Message',
            'foreignKey' => 'to'
         )
    );
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array(
        'UserFrom' => array(
            'className'  => 'User',
            'foreignKey' => 'from'
        )
    );
    public $hasMany = array(
        'UserTo' => array(
            'className'  => 'User',
            'foreignKey' => 'to'
        )
    );
}

Now you can do your find call like this:

$this->Message->find('all', array(
    'contain' => array('UserFrom')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

I was getting exception

java.util.zip.ZipException: invalid entry CRC (expected 0x0 but got 0xdeadface)
    at java.util.zip.ZipInputStream.read(ZipInputStream.java:221)
    at java.util.zip.ZipInputStream.closeEntry(ZipInputStream.java:140)

I switched to Apache Commons Compress for reading the zip-entries and that resolved the problem.

class Node:
    def __init__(self, wordList=None adjacencyList=None):
        self.wordList = wordList or []
        self.adjacencyList = adjacencyList or []

Your question is kind of confusing; do you want to show only one row per user, or do you want to show a row per picture but suppress repeating values in the U.NAME field? I think you want the second; if not there are plenty of answers for the first.

Whether to display repeating values is display logic, which SQL wasn't really designed for. You can use a cursor in a loop to process the results row-by-row, but you will lose a lot of performance. If you have a "smart" frontend language like a .NET language or Java, whatever construction you put this data into can be cheaply manipulated to suppress repeating values before finally displaying it in the UI.

If you're using Microsoft SQL Server, and the transformation HAS to be done at the data layer, you may consider using a CTE (Computed Table Expression) to hold the initial query, then select values from each row of the CTE based on whether the columns in the previous row hold the same data. It'll be more performant than the cursor, but it'll be kinda messy either way. Observe:

USING CTE (Row, Name, PicID)
AS
(
    SELECT ROW_NUMBER() OVER (ORDER BY U.NAME, P.PIC_ID),
       U.NAME, P.PIC_ID
    FROM USERS U
        INNER JOIN POSTINGS P1
            ON U.EMAIL_ID = P1.EMAIL_ID
        INNER JOIN PICTURES P
            ON P1.PIC_ID = P.PIC_ID
    WHERE P.CAPTION LIKE '%car%'
    ORDER BY U.NAME, P.PIC_ID 
)
SELECT
    CASE WHEN current.Name == previous.Name THEN '' ELSE current.Name END,
    current.PicID
FROM CTE current
LEFT OUTER JOIN CTE previous
   ON current.Row = previous.Row + 1
ORDER BY current.Row

The above sample is TSQL-specific; it is not guaranteed to work in any other DBPL like PL/SQL, but I think most of the enterprise-level SQL engines have something similar.

Like user2680100 said, in Golang you can have the structure:

if <statement>; <evaluation> {
    [statements ...]
} else {
    [statements ...]
}

This is useful to shortcut some expressions that need error checking, or another kind of boolean checking, like:

var number int64
if v := os.Getenv("NUMBER"); v != "" {
   if number, err = strconv.ParseInt(v, 10, 64); err != nil {
       os.Exit(42)
   }
} else {
    os.Exit(1)
}

With this you can achieve something like (in C):

Sprite *buffer = get_sprite("foo.png");
Sprite *foo_sprite = (buffer != 0) ? buffer : donut_sprite

But is evident that this sugar in Golang have to be used with moderation, for me, personally, I like to use this sugar with max of one level of nesting, like:

var number int64
if v := os.Getenv("NUMBER"); v != "" {
    number, err = strconv.ParseInt(v, 10, 64)
    if err != nil {
        os.Exit(42)
    }
} else {
    os.Exit(1)
}

You can also implement ternary expressions with functions like func Ternary(b bool, a interface{}, b interface{}) { ... } but i don't like this approach, looks like a creation of a exception case in syntax, and creation of this "features", in my personal opinion, reduce the focus on that matters, that is algorithm and readability, but, the most important thing that makes me don't go for this way is that fact that this can bring a kind of overhead, and bring more cycles to in your program execution.

If you mean you want to sort by date first then by names

SELECT id, name, form_id, DATE(updated_at) as date
  FROM wp_frm_items
  WHERE user_id = 11 && form_id=9
  ORDER BY updated_at DESC,name ASC

This will sort the records by date first, then by names

To prove There's More Than One Six Ways To Do It:

plus_1 = 1.method(:+)
Array.new(3, &plus_1) # => [1, 2, 3]

If 1.method(:+) wasn't possible, you could also do

plus_1 = Proc.new {|n| n + 1}
Array.new(3, &plus_1) # => [1, 2, 3]

Sure, it's overkill in this scenario, but if plus_1 was a really long expression, you might want to put it on a separate line from the array creation.

There is currently no way to do this out of the box, but there is a User Voice suggestion for adding it: http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2037649-implement-indexed-full-text-search-of-work-items

While I doubt it is as simple as flipping a switch, if everyone that has viewed this question voted for it, MS would probably implement something.

Update: Just read Brian Harry's blog, which shows this request as being on their radar, and the Online version of Visual Studio has limited support for searching where git is used as the vcs: http://blogs.msdn.com/b/visualstudioalm/archive/2015/02/13/announcing-limited-preview-for-visual-studio-online-code-search.aspx. From this I think it's fair to say it is just a matter of time...

Update 2: There is now a Microsoft provided extension,Code Search which enables searching in code as well as in work items.

This error can occur when you rename files outside of XCode. To solve it you can just remove the files from your project (Right Click - Delete and "Remove Reference").

Then after you can re-import the files in your project and everything will be OK.

You can try Context.getApplicationInfo().dataDir if you want the package's persistent data folder.

getFilesDir() returns a subroot of this.

I encountered the same problem In my case, I solved the problem in this way

Step 1: From start menu went to SQL server configuration manager

Step 2: Enabled TCP/IP

Step 3: Double clicked TCP/IP and went to IP Address last entry IP ALL and entered TCP Port 1433 then applied

Step 4 : then pressed win+r and wrote services.msc opened the Services then scrolled down then right clicked on SQL Server (MSSQLSERVER) choose restart

That resolved my problem. Even if doing all of the above steps do not solve the problem then simply restart the PC then hopefully it will work.

Late answer (8 yrs), but for someone looking to join multiple files into one, the following function may be of help:

def multi_open(_list):
    out=""
    for x in _list:
        try:
            with open(x) as f:
                out+=f.read()
        except:
            pass
            # print(f"Cannot open file {x}")
    return(out)

fl = ["C:/bdlog.txt", "C:/Jts/tws.vmoptions", "C:/not.exist"]
print(multi_open(fl))

Use Ctrl+K. This goes clean your console in Visual Studio Code.

Per comments, in later versions of VSCode (1.29 and above) this shortcut is missing / needs to be created manually.

• Navigate: File > Preferences > Keyboard Shortcuts
• search for workbench.action.terminal.clear
• If it has no mapping or you wish to change the mapping, continue; otherwise note & use the existing mapping
• Double click on this entry & you'll be prompted for a key binding. Hold CTRL and tap K. Ctrl + K should now be listed. Press enter to save this mapping
• Right click the entry and select Change when expression. Type terminalFocus then press enter.
• That's it. Now, when the terminal is in focus and you press ctrl+k you'll get the behaviour you'd have expected to get from running clear/cls.

Assuming a as double and we need a rounded number with no decimal place . Use Math.round() function.
This goes as my solution .

double a = 0.99999;
int rounded_a = (int)Math.round(a);
System.out.println("a:"+rounded_a );

Output : 
a:1

The volatile and transient modifiers can be applied to fields of classes¹ irrespective of field type. Apart from that, they are unrelated.

The transient modifier tells the Java object serialization subsystem to exclude the field when serializing an instance of the class. When the object is then deserialized, the field will be initialized to the default value; i.e. null for a reference type, and zero or false for a primitive type. Note that the JLS (see 8.3.1.3) does not say what transient means, but defers to the Java Object Serialization Specification. Other serialization mechanisms may pay attention to a field's transient-ness. Or they may ignore it.

(Note that the JLS permits a static field to be declared as transient. This combination doesn't make sense for Java Object Serialization, since it doesn't serialize statics anyway. However, it could make sense in other contexts, so there is some justification for not forbidding it outright.)

The volatile modifier tells the JVM that writes to the field should always be synchronously flushed to memory, and that reads of the field should always read from memory. This means that fields marked as volatile can be safely accessed and updated in a multi-thread application without using native or standard library-based synchronization. Similarly, reads and writes to volatile fields are atomic. (This does not apply to >>non-volatile<< long or double fields, which may be subject to "word tearing" on some JVMs.) The relevant parts of the JLS are 8.3.1.4, 17.4 and 17.7.

After reading all these post It created more confuse for me.. But still all is worthfull information.. finally I found following table which will give information with simple comparision

• The injector uses recipes to create two types of objects: services and special purpose objects
• There are five recipe types that define how to create objects: Value, Factory, Service, Provider and Constant.
• Factory and Service are the most commonly used recipes. The only difference between them is that the Service recipe works better for objects of a custom type, while the Factory can produce JavaScript primitives and functions.
• The Provider recipe is the core recipe type and all the other ones are just syntactic sugar on it.
• Provider is the most complex recipe type. You don't need it unless you are building a reusable piece of code that needs global configuration.
• All special purpose objects except for the Controller are defined via Factory recipes.

And for beginner understand:- This may not correct use case but in high level this is what usecase for these three.

1. If you want to use in angular module config function should created as provider

angular.module('myApp').config(function($testProvider){_x000D_
$testProvider.someFunction();_x000D_
})

2. Ajax call or third party integrations needs to be service.
3. For Data manipulations create it as factory

For basic scenarios factory&Service behaves same.

To access the mysql command in Windows without manually changing directories, do this:

• Go to Control Panel > System > Advanced system settings.
• System Properties will appear.
• Click on the 'Advanced' tab.
• Click 'Environment Variables'.
• Under System Variables, locate 'Path' and click Edit.

• Append the path to your MySQL installation to the end of the exisiting 'Variable value'. Example:

  %systemDrive%\xampp\mysql\bin\ 

  or, if you prefer

  c:\xampp\mysql\bin\ 

• Finally, open a new command prompt to make this change take effect.

Note that MySQL's documentation on Setting Environment Variables has little to say about handling this in Windows.

The easiest and fastest way to convert a Pandas dataframe into a png image using Anaconda Spyder IDE- just double-click on the dataframe in variable explorer, and the IDE table will appear, nicely packaged with automatic formatting and color scheme. Just use a snipping tool to capture the table for use in your reports, saved as a png:

This saves me lots of time, and is still elegant and professional.

Opening a file creates it and (unless append ('a') is set) overwrites it with emptyness, such as this:

open(filename, 'w').close()

If all you need to do is to turn file arguments.txt with contents

arg1
arg2
argN

into my_command arg1 arg2 argN then you can simply use xargs:

xargs -a arguments.txt my_command

You can put additional static arguments in the xargs call, like xargs -a arguments.txt my_command staticArg which will call my_command staticArg arg1 arg2 argN

The presence of the n option attached to the -k5 causes the global -r option to be ignored for that field. You have to specify both n and r at the same level (globally or locally).

sort -t $'\t' -k5,5rn

or

sort -rn -t $'\t' -k5,5

I almost never use Boolean because its semantics are vague and obscure. Basically you have 3-state logic: true, false or unknown. Sometimes it is useful to use it when e.g. you gave user a choice between two values and the user didn't answer at all and you really want to know that information (think: NULLable database column).

I see no reason to convert from boolean to Boolean as it introduces extra memory overhead, NPE possibility and less typing. Typically I use awkward BooleanUtils.isTrue() to make my life a little bit easier with Boolean.

The only reason for the existence of Boolean is the ability to have collections of Boolean type (generics do not allow boolean, as well as all other primitives).

An alternative solution is to configure your project through cmake-gui, starting from a clean build directory. Among the options you have available at the beginning, there's the possibility to choose the exact path to the compilers

I wanted a very similar thing because I wanted to put the function name in a log string that went in a number of places in my code. Probably not the best way to do that, but here's a way to get the name of the current function.

Most likely JDK configuration is not valid, try to remove and add the JDK again as I've described in the related question here.

I like Kango_V's answer, but I think it's too complex. I think this is simpler - maybe too simple. If inclined, you could replace String with a Generic marker, and make it work for any Key type.

public static <E> Map<String, E> convertListToMap(Collection<E> sourceList, ListToMapConverterInterface<E> converterInterface) {
    Map<String, E> newMap = new HashMap<String, E>();
    for( E item : sourceList ) {
        newMap.put( converterInterface.getKeyForItem( item ), item );
    }
    return newMap;
}

public interface ListToMapConverterInterface<E> {
    public String getKeyForItem(E item);
}

Used like this:

        Map<String, PricingPlanAttribute> pricingPlanAttributeMap = convertListToMap( pricingPlanAttributeList,
                new ListToMapConverterInterface<PricingPlanAttribute>() {

                    @Override
                    public String getKeyForItem(PricingPlanAttribute item) {
                        return item.getFullName();
                    }
                } );

When tree width is very large and depth is low use DFS as recursion stack will not overflow.Use BFS when width is low and depth is very large to traverse the tree.

A standard-lib version (no pandas)

This assumes that the first row of the csv is the headers

import csv

# open the file in universal line ending mode 
with open('test.csv', 'rU') as infile:
  # read the file as a dictionary for each row ({header : value})
  reader = csv.DictReader(infile)
  data = {}
  for row in reader:
    for header, value in row.items():
      try:
        data[header].append(value)
      except KeyError:
        data[header] = [value]

# extract the variables you want
names = data['name']
latitude = data['latitude']
longitude = data['longitude']

You can use DateFormat(java.text.*) to parse the date:

DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy", Locale.ENGLISH);
Date d = df.parse("Mon May 27 11:46:15 IST 2013")

You will have to change the locale to match your own (with this you will get 10:46:15). Then you can use the same code you have to convert it to a timestamp.

Use the SETX command (note the 'x' suffix) to set variables that persist after the cmd window has been closed.

For example, to set an env var "foo" with value of "bar":

setx foo bar

Though it's worth reading the 'notes' that are displayed if you print the usage (setx /?), in particular:

2) On a local system, variables created or modified by this tool will be available in future command windows but not in the current CMD.exe command window.

3) On a remote system, variables created or modified by this tool will be available at the next logon session.

In PowerShell, the [Environment]::SetEnvironmentVariable command.

Here is one good source of this in JavaScript.

Here is the summary:

• global this

  In a browser, at the global scope, this is the windowobject

  <script type="text/javascript">
    console.log(this === window); // true
    var foo = "bar";
    console.log(this.foo); // "bar"
    console.log(window.foo); // "bar"
  

  In node using the repl, this is the top namespace. You can refer to it as global.

  >this
    { ArrayBuffer: [Function: ArrayBuffer],
      Int8Array: { [Function: Int8Array] BYTES_PER_ELEMENT: 1 },
      Uint8Array: { [Function: Uint8Array] BYTES_PER_ELEMENT: 1 },
      ...
  >global === this
   true
  

  In node executing from a script, this at the global scope starts as an empty object. It is not the same as global

  \\test.js
  console.log(this);  \\ {}
  console.log(this === global); \\ fasle
  

• function this

Except in the case of DOM event handlers or when a thisArg is provided (see further down), both in node and in a browser using this in a function that is not called with new references the global scope…

<script type="text/javascript">
    foo = "bar";

    function testThis() {
      this.foo = "foo";
    }

    console.log(this.foo); //logs "bar"
    testThis();
    console.log(this.foo); //logs "foo"
</script>

If you use use strict;, in which case this will be undefined

<script type="text/javascript">
    foo = "bar";

    function testThis() {
      "use strict";
      this.foo = "foo";
    }

    console.log(this.foo); //logs "bar"
    testThis();  //Uncaught TypeError: Cannot set property 'foo' of undefined 
</script>

If you call a function with new the this will be a new context, it will not reference the global this.

<script type="text/javascript">
    foo = "bar";

    function testThis() {
      this.foo = "foo";
    }

    console.log(this.foo); //logs "bar"
    new testThis();
    console.log(this.foo); //logs "bar"

    console.log(new testThis().foo); //logs "foo"
</script>

• prototype this

Functions you create become function objects. They automatically get a special prototype property, which is something you can assign values to. When you create an instance by calling your function with new you get access to the values you assigned to the prototype property. You access those values using this.

function Thing() {
  console.log(this.foo);
}

Thing.prototype.foo = "bar";

var thing = new Thing(); //logs "bar"
console.log(thing.foo);  //logs "bar"

It is usually a mistake to assign arrays or objects on the prototype. If you want instances to each have their own arrays, create them in the function, not the prototype.

function Thing() {
    this.things = [];
}

var thing1 = new Thing();
var thing2 = new Thing();
thing1.things.push("foo");
console.log(thing1.things); //logs ["foo"]
console.log(thing2.things); //logs []

• object this

You can use this in any function on an object to refer to other properties on that object. This is not the same as an instance created with new.

var obj = {
    foo: "bar",
    logFoo: function () {
        console.log(this.foo);
    }
};

obj.logFoo(); //logs "bar"

• DOM event this

In an HTML DOM event handler, this is always a reference to the DOM element the event was attached to

function Listener() {
    document.getElementById("foo").addEventListener("click",
       this.handleClick);
}
Listener.prototype.handleClick = function (event) {
    console.log(this); //logs "<div id="foo"></div>"
}

var listener = new Listener();
document.getElementById("foo").click();

Unless you bind the context

function Listener() {
    document.getElementById("foo").addEventListener("click", 
        this.handleClick.bind(this));
}
Listener.prototype.handleClick = function (event) {
    console.log(this); //logs Listener {handleClick: function}
}

var listener = new Listener();
document.getElementById("foo").click();

• HTML this

Inside HTML attributes in which you can put JavaScript, this is a reference to the element.

<div id="foo" onclick="console.log(this);"></div>
<script type="text/javascript">
document.getElementById("foo").click(); //logs <div id="foo"...
</script>

• eval this

You can use eval to access this.

function Thing () {
}
Thing.prototype.foo = "bar";
Thing.prototype.logFoo = function () {
    eval("console.log(this.foo)"); //logs "bar"
}

var thing = new Thing();
thing.logFoo();

• with this

You can use with to add this to the current scope to read and write to values on this without referring to this explicitly.

function Thing () {
}
Thing.prototype.foo = "bar";
Thing.prototype.logFoo = function () {
    with (this) {
        console.log(foo);
        foo = "foo";
    }
}

var thing = new Thing();
thing.logFoo(); // logs "bar"
console.log(thing.foo); // logs "foo"

• jQuery this

the jQuery will in many places have this refer to a DOM element.

<div class="foo bar1"></div>
<div class="foo bar2"></div>
<script type="text/javascript">
$(".foo").each(function () {
    console.log(this); //logs <div class="foo...
});
$(".foo").on("click", function () {
    console.log(this); //logs <div class="foo...
});
$(".foo").each(function () {
    this.click();
});
</script>

Easiest solution for your question, it worked in my case:

import string
def solve(s):
    return string.capwords(s,' ') 
    
s=input()
res=solve(s)
print(res)

Best way to do this is to make it check against an IP address that python always gives if it can't find the website. In this case this is my code:

import socket

print("website connection checker")
while True:
    website = input("please input website: ")
    print("")
    print(socket.gethostbyname(website))
    if socket.gethostbyname(website) == "92.242.140.2":
        print("Website could be experiencing an issue/Doesn't exist")
    else:
        socket.gethostbyname(website)
        print("Website is operational!")
        print("")

Do as follow,

• Click on commit
• Select all by pressing CMD+A that you want to delete or discard
• Right click on the selected uncommitted files that you want to delete
• Select Remove from the drop-down list

I had denied insert and reload privileges to root. So after updating permissions, FLUSH PRIVILEGES was not working (due to lack of reload privilege). So I used debian-sys-maint user on Ubuntu 16.04 to restore user.root privileges. You can find password of user.debian-sys-maint from this file

Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:

The main idea behind this is to encapsulate the text and the circle in the same "div" as you would do in html to have the logo and the name of the company in the same div in a page header.

The main code is:

var width = 960,
    height = 500;

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height)

d3.json("data.json", function(json) {
    /* Define the data for the circles */
    var elem = svg.selectAll("g")
        .data(json.nodes)

    /*Create and place the "blocks" containing the circle and the text */  
    var elemEnter = elem.enter()
        .append("g")
        .attr("transform", function(d){return "translate("+d.x+",80)"})

    /*Create the circle for each block */
    var circle = elemEnter.append("circle")
        .attr("r", function(d){return d.r} )
        .attr("stroke","black")
        .attr("fill", "white")

    /* Create the text for each block */
    elemEnter.append("text")
        .attr("dx", function(d){return -20})
        .text(function(d){return d.label})
})

and the json file is:

{"nodes":[
  {"x":80, "r":40, "label":"Node 1"}, 
  {"x":200, "r":60, "label":"Node 2"}, 
  {"x":380, "r":80, "label":"Node 3"}
]}

The resulting html code shows the encapsulation you want:

<svg width="960" height="500">
    <g transform="translate(80,80)">
        <circle r="40" stroke="black" fill="white"></circle>
        <text dx="-20">Node 1</text>
    </g>
    <g transform="translate(200,80)">
        <circle r="60" stroke="black" fill="white"></circle>
        <text dx="-20">Node 2</text>
    </g>
    <g transform="translate(380,80)">
        <circle r="80" stroke="black" fill="white"></circle>
        <text dx="-20">Node 3</text>
    </g>
</svg>

this is my working batch

You could still use sortBy (at the collection level) instead of orderBy (at the query level) if you still want to use all() since it returns a collection of objects.

Ascending Order

$results = Project::all()->sortBy("name");

Descending Order

$results = Project::all()->sortByDesc("name");

To make my FFMPEG application I used this project (https://github.com/hiteshsondhi88/ffmpeg-android-java) so, I don't have to compile anything. I think it's the easy way to use FFMPEG in our Android applications.

Faced myself and seen several times in comments for similar questions - that even after installing "latest" Google Play Services and Google Repository still having the same issue.

The thing is that they may be latest for your current revision of Android SDK Tools, but not that latest your app build requires.

In such case make sure to install latest version of Android SDK Tools first, and probably Android SDK Platform-tools (both under Tools branch). Also please note you may need to go through this several times if you haven't updated for a long time (i.e. install latest Android SDK Tools and Android SDK Platform-tools, then restart Android SDK Manager, then repeat), since the updates seem to be going through some critical mandatory milestones and you cannot install the very latest if you currently have the revision which is pretty "old".

Thank you Guys to give me many suggestions. Finally I got a solution. That is i have started the NetErrorPage intent two times. One time, i have checked the net connection availability and started the intent in page started event. second time, if the page has error, then i have started the intent in OnReceivedError event. So the first time dialog is not closed, before that the second dialog is called. So that i got a error.

Reason for the Error: I have called the showInfoMessageDialog method two times before closing the first one.

Now I have removed the second call and Cleared error :-).

One way to do this is to pull your field into the rows section of the pivot table from the Filter section. Then group the values that you want to keep into a group, using the group option on the menu. After that is completed, drag your field back into the Filters section. The grouping will remain and you can check or uncheck one box to remove lots of values.

Try to execute below command in your terminal :

mysql -h localhost -P 3306 -u root -p

If you successfully connect to your database, then same thing has to happen with Mysql Workbench.

If you are unable to connect then I think 3306 port is acquired by another process.

Find which process running on 3306 port. If required, give admin privileges using sudo.

netstat -lnp | grep 3306

Kill/stop that process and restart your MySQL server. You are good to go.

Execute below command to find my.cnf file in macbook.

mysql --help | grep cnf

You can change MySQL port to any available port in your system. But after that, make sure you restart MySQL server.

The API >= 11 solution:

You can integrate the padding into divider. In case you were using none, just create a tall empty drawable and set it as LinearLayout's divider:

    <LinearLayout
            android:showDividers="middle"
            android:divider="@drawable/empty_tall_divider"
...>...</LinearLayout>

empty_tall_divider.xml:

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

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <size
            android:height="40dp"
            android:width="0dp"/>
</shape>

Since its mentioned in Android documentation that AAPT has been deprecated, getting the package name using AAPT2 command in Linux is as follows:

./aapt2 dump packagename <path_to_apk>

Since I am using an older version of Gradle build, I had to download a newer version of AAPT2 as mentioned here :

Download AAPT2 from Google Maven

Using the build-tools in my sdk - 25.0.3, 26.0.1 and 27.0.3, executing the aapt2 command shows an error: Unable to open 'packagename': No such file or directory. That's why I went for the newer versions of AAPT2.

I used 3.3.0-5013011 for linux.

This will give a list of selected

List<ListItem> items =  checkboxlist.Items.Cast<ListItem>().Where(n => n.Selected).ToList();

This will give a list of the selected boxes' values (change Value for Text if that is wanted):

var values =  checkboxlist.Items.Cast<ListItem>().Where(n => n.Selected).Select(n => n.Value ).ToList()

somevar = tag.getArtist()

I had similar issues (I tried to create a nested RecyclerViews something like Google PlayStore design). The best way to deal with this is by subclassing the child RecyclerViews and overriding the 'onInterceptTouchEvent' and 'onTouchEvent' methods. This way you get complete control of how those events behave and eventually scrolling.

I assert that you are using HiveServer2, which is the reason that makes the code doesn't work.

You may use pyhs2 to access your Hive correctly and the example code like that:

import pyhs2

with pyhs2.connect(host='localhost',
               port=10000,
               authMechanism="PLAIN",
               user='root',
               password='test',
               database='default') as conn:
    with conn.cursor() as cur:
        #Show databases
        print cur.getDatabases()

        #Execute query
        cur.execute("select * from table")

        #Return column info from query
        print cur.getSchema()

        #Fetch table results
        for i in cur.fetch():
            print i

Attention that you may install python-devel.x86_64 cyrus-sasl-devel.x86_64 before installing pyhs2 with pip.

Wish this can help you.

I was also having this same problem. I developed a synchronous solution thanks to the research done by @tpeczek in the following SO article: Unable to authenticate to ASP.NET Web Api service with HttpClient

My solution uses a WebClient, which as you correctly noted passes the credentials without issue. The reason HttpClient doesn't work is because of Windows security disabling the ability to create new threads under an impersonated account (see SO article above.) HttpClient creates new threads via the Task Factory thus causing the error. WebClient on the other hand, runs synchronously on the same thread thereby bypassing the rule and forwarding its credentials.

Although the code works, the downside is that it will not work async.

var wi = (System.Security.Principal.WindowsIdentity)HttpContext.Current.User.Identity;

var wic = wi.Impersonate();
try
{
    var data = JsonConvert.SerializeObject(new
    {
        Property1 = 1,
        Property2 = "blah"
    });

    using (var client = new WebClient { UseDefaultCredentials = true })
    {
        client.Headers.Add(HttpRequestHeader.ContentType, "application/json; charset=utf-8");
        client.UploadData("http://url/api/controller", "POST", Encoding.UTF8.GetBytes(data));
    }
}
catch (Exception exc)
{
    // handle exception
}
finally
{
    wic.Undo();
}

Note: Requires NuGet package: Newtonsoft.Json, which is the same JSON serializer WebAPI uses.

if rate is the sampling rate(Hz), then np.linspace(0, rate/2, n) is the frequency array of every point in fft. You can use rfft to calculate the fft in your data is real values:

import numpy as np
import pylab as pl
rate = 30.0
t = np.arange(0, 10, 1/rate)
x = np.sin(2*np.pi*4*t) + np.sin(2*np.pi*7*t) + np.random.randn(len(t))*0.2
p = 20*np.log10(np.abs(np.fft.rfft(x)))
f = np.linspace(0, rate/2, len(p))
plot(f, p)

signal x contains 4Hz & 7Hz sin wave, so there are two peaks at 4Hz & 7Hz.

I created a tiny JQuery plugin for this. You may try it:

$.poll('http://my/url', 100, (xhr, status, data) => {
    return data.hello === 'world';
})

https://www.npmjs.com/package/jquerypoll

This works for me in irb:

irb> (1..4).to_a
=> [1, 2, 3, 4]

I notice that:

irb> 1..4.to_a
(irb):1: warning: default `to_a' will be obsolete
ArgumentError: bad value for range
        from (irb):1

So perhaps you are missing the parentheses?

Please remember that Google also use reCaptcha together with

Canvas fingerprinting 

to uniquely recognize User/Browsers without cookies!

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

In that case you should use ListBox control instead of dropdown and Set the SelectionMode property to Multiple

<asp:ListBox runat="server" SelectionMode="Multiple" >
  <asp:ListItem Text="test1"></asp:ListItem>
  <asp:ListItem Text="test2"></asp:ListItem>
  <asp:ListItem Text="test3"></asp:ListItem>
</asp:ListBox>

You should use dynamic object to resolve combobox item in run-time.

You can use gridspec and figure:

import numpy as np
import matplotlib.pyplot as plt 
from matplotlib import gridspec

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
fig = plt.figure(figsize=(8, 6)) 
gs = gridspec.GridSpec(1, 2, width_ratios=[3, 1]) 
ax0 = plt.subplot(gs[0])
ax0.plot(x, y)
ax1 = plt.subplot(gs[1])
ax1.plot(y, x)

plt.tight_layout()
plt.savefig('grid_figure.pdf')

It seems that you are looking to parse commandline arguments into your bash script. I have searched for this recently myself. I came across the following which I think will assist you in parsing the arguments:

http://rsalveti.wordpress.com/2007/04/03/bash-parsing-arguments-with-getopts/

I added the snippet below as a tl;dr

#using : after a switch variable means it requires some input (ie, t: requires something after t to validate while h requires nothing.
while getopts “ht:r:p:v” OPTION
do
     case $OPTION in
         h)
             usage
             exit 1

             usage
             exit
             ;;

November 2019: onclick="self.close()" still works in Chrome while Edge gives a warning that must be confirmed before it will close.

On the other hand the solution onclick="window.open('', '_self', ''); window.close();" works in both.

1.First you have to set the getItemposition method in your Pageradapter class 2.You have to read the Exact position of your View Pager 3.then send that position as data location of your new one 4.Write update button onclick listener inside the setonPageChange listener

that program code is little bit i modified to set the particular position element only

public class MyActivity extends Activity {

private ViewPager myViewPager;
private List<String> data;
public int location=0;
public Button updateButton;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    data = new ArrayList<String>();
    data.add("A");
    data.add("B");
    data.add("C");
    data.add("D");
    data.add("E");
    data.add("F");

    myViewPager = (ViewPager) findViewById(R.id.pager);
    myViewPager.setAdapter(new MyViewPagerAdapter(this, data));

      updateButton = (Button) findViewById(R.id.update);

    myViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int i, float v, int i2) {
             //Toast.makeText(MyActivity.this, i+"  Is Selected  "+data.size(), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onPageSelected( int i) {
          // here you will get the position of selected page
            final int k = i;
             updateViewPager(k);

        }

        @Override
        public void onPageScrollStateChanged(int i) {

        }
    });
}

private void updateViewPager(final int i) {  
    updateButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            Toast.makeText(MyActivity.this, i+"  Is Selected  "+data.size(), Toast.LENGTH_SHORT).show();
            data.set(i, "Replaced "+i);         
            myViewPager.getAdapter().notifyDataSetChanged();
        }
    });

}

private class MyViewPagerAdapter extends PagerAdapter {

    private List<String> data;
    private Context ctx;

    public MyViewPagerAdapter(Context ctx, List<String> data) {
        this.ctx = ctx;
        this.data = data;
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public int getItemPosition(Object object) {
        return POSITION_NONE;
    }

    @Override
    public Object instantiateItem(View collection, int position) {          

        TextView view = new TextView(ctx);
        view.setText(data.get(position));
        ((ViewPager)collection).addView(view);            
        return view;
    }

    @Override
    public void destroyItem(View collection, int position, Object view) {
         ((ViewPager) collection).removeView((View) view);
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }

    @Override
    public Parcelable saveState() {
        return null;
    }

    @Override
    public void restoreState(Parcelable arg0, ClassLoader arg1) {
    }

    @Override
    public void startUpdate(View arg0) {
    }

    @Override
    public void finishUpdate(View arg0) {
    }
}
}

I agree with @pkozlowski.opensource answer, but ng-clock class did't work for me for using with ng-repeat. so I would like to recommend you to use class for simple delimiter expression like {{name}} and ngCloak directive for ng-repeat.

<div class="ng-cloak">{{name}}<div>

and

<li ng-repeat="item in items" ng-cloak>{{item.name}}<li>

(in answer to the second question) By only using a sign bit (and not 2's complement), you can end up with -0. Not very pretty.

I read all the above answers and those are actually good.

look at this code:

for i in range(1, 4):
    print("Before change:", i)
    i = 20 # changing i variable
    print("After change:", i) # this line will always print 20

When we execute above code the output is like below,

Before Change: 1
After change: 20
Before Change: 2
After change: 20
Before Change: 3
After change: 20

in python for loop is not trying to increase i value. for loop is just assign values to i which we gave. Using range(4) what we are doing is we give the values to for loop which need assign to the i.

You can use while loop instead of for loop to do same thing what you want,

i = 0
while i < 6:
    print(i)
    j = 0
    while j < 5:
        i += 2 # to increase `i` by 2

This will give,

0
2
4

Thank you !

You can use MongoDB_DataObject wrapper to perform such query like below:

$model = new MongoDB_DataObject('orders');

$model->whereAdd('MONTH(created) = 4 AND YEAR(created) = 2016');

$model->find();

while ($model->fetch()) {
    var_dump($model);
}

OR, similarly, using direct query string:

$model = new MongoDB_DataObject();

$model->query('SELECT * FROM orders WHERE MONTH(created) = 4 AND YEAR(created) = 2016');

while ($model->fetch()) {
    var_dump($model);
}

The problem is your plugin. To solve this is to only enter this address:

chrome://flags/#enable-NPAPI

Click activate NPAPI, and finally restart at the bottom of the page.

As a general advice, I would recommend not stealing the focus from the address bar. (Jeff already talked about that.)

Web page can take some time to load, which means that your focus change can occur some long time after the user typed the pae URL. Then he could have changed his mind and be back to url typing while you will be loading your page and stealing the focus to put it in your textbox.

That's the one and only reason that made me remove Google as my start page.

Of course, if you control the network (local network) or if the focus change is to solve an important usability issue, forget all I just said :)

Create a temporary element, then clone() and append():

$('<div>').append($('#xxx').clone()).html();

I had a problem with the white screen after installing a new laravel instance. I couldn't find anything in the logs because (eventually I found out) that the reason for the white screen was that app/storage wasn't writable.

In order to get an error message on the screen I added the following to the public/index.php

try {
    $app->run();
} catch(\Exception $e) {
    echo "<pre>";
    echo $e;
    echo "</pre>";
}

After that it was easy to solve the problem.

In my case, the problem was with the specific box I was trying to use ubuntu/xenial64, I just had to switch to centos/7 and all those errors disappeared.

Hope this helps someone.

you say "export to file" as in a spreadsheet? like to a .csv?

IMO this is the EASIEST way to do this in Robo 3T (formerly robomongo):

1. In the top right of the Robo 3T GUI there is a "View Results in text mode" button, click it and copy everything

2. paste everything into this website: https://json-csv.com/

3. click the download button and now you have it in a spreadsheet.

hope this helps someone, as I wish Robo 3T had export capabilities

I've created a workaround that seems to be working pretty well. I found the need to switch to the context of a different controller for action name lookup, view lookup, etc. To implement this, I created a new extension method for HtmlHelper:

public static IDisposable ControllerContextRegion(
    this HtmlHelper html, 
    string controllerName)
{
    return new ControllerContextRegion(html.ViewContext.RouteData, controllerName);
}

ControllerContextRegion is defined as:

internal class ControllerContextRegion : IDisposable
{
    private readonly RouteData routeData;
    private readonly string previousControllerName;

    public ControllerContextRegion(RouteData routeData, string controllerName)
    {
        this.routeData = routeData;
        this.previousControllerName = routeData.GetRequiredString("controller");
        this.SetControllerName(controllerName);
    }

    public void Dispose()
    {
        this.SetControllerName(this.previousControllerName);
    }

    private void SetControllerName(string controllerName)
    {
        this.routeData.Values["controller"] = controllerName;
    }
}

The way this is used within a view is as follows:

@using (Html.ControllerContextRegion("Foo")) {
    // Html.Action, Html.Partial, etc. now looks things up as though
    // FooController was our controller.
}

There may be unwanted side effects for this if your code requires the controller route component to not change, but in our code so far, there doesn't seem to be any negatives to this approach.

Excellent answer already provide onsite here.

See the summary below:

1. Go to the Build Path settings in the project properties.
2. Remove the JRE System Library
3. Add it back; Select "Add Library" and select the JRE System Library. The default worked for me.

If you just want to apply a function to each element and put the results in an output array, you can use arrayfun.

As others have pointed out, for most operations, it's best to avoid loops in MATLAB and vectorise your code instead.

See this answer: Source

If timezone is not specified in postgresql.conf or as a server command-line option, the server attempts to use the value of the TZ environment variable as the default time zone. If TZ is not defined or is not any of the time zone names known to PostgreSQL, the server attempts to determine the operating system's default time zone by checking the behavior of the C library function localtime(). The default time zone is selected as the closest match among PostgreSQL's known time zones. (These rules are also used to choose the default value of log_timezone, if not specified.) source

This means that if you do not define a timezone, the server attempts to determine the operating system's default time zone by checking the behavior of the C library function localtime().

If timezone is not specified in postgresql.conf or as a server command-line option, the server attempts to use the value of the TZ environment variable as the default time zone.

It seems to have the System's timezone to be set is possible indeed.

Get the OS local time zone from the shell. In psql:

=> \! date +%Z

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

your string is NOT a valid json to start with.

a valid json will be,

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

if you do a json_decode, it will yield,

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

Update: to use

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

';
            $area = json_decode($string, true);

            foreach($area['area'] as $i => $v)
            {
                echo $v['area'].'<br/>';
            }

Output:

kothrud
katraj

Update #2:

for that true:

When TRUE, returned objects will be converted into associative arrays. for more information, click here

Try

#include <inttypes.h>
...

printf("i [ %zu ] k [ %"PRIu32" ]\n", i, k);

The z represents an integer of length same as size_t, and the PRIu32 macro, defined in the C99 header inttypes.h, represents an unsigned 32-bit integer.

Something like this should work unless I'm missing the point:

import json
import urllib2
json.load(urllib2.urlopen("url"))

If you want to avoid npm install and not running in browser, you can also use nodejs https module;

const https = require('https')
const url = "https://jsonmock.hackerrank.com/api/movies";
https.get(url, res => {
  let data = '';
  res.on('data', chunk => {
    data += chunk;
  });
  res.on('end', () => {
    data = JSON.parse(data);
    console.log(data);
  })
}).on('error', err => {
  console.log(err.message);
})

Although it is safe to declare a static ObjectMapper in terms of thread safety, you should be aware that constructing static Object variables in Java is considered bad practice. For more details, see Why are static variables considered evil? (and if you'd like, my answer)

In short, statics should be avoided because the make it difficult to write concise unit tests. For example, with a static final ObjectMapper, you can't swap out the JSON serialization for dummy code or a no-op.

In addition, a static final prevents you from ever reconfiguring ObjectMapper at runtime. You might not envision a reason for that now, but if you lock yourself into a static final pattern, nothing short of tearing down the classloader will let you re-initialize it.

In the case of ObjectMapper its fine, but in general it is bad practice and there is no advantage over using a singleton pattern or inversion-of-control to manage your long-lived objects.

Table name change

RENAME TABLE old_table_name TO new_table_name;

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

This is maybe not the case of original OP question, but: if you exceeds the default max size, this maybe a symptom of some other issue you have. in my case, I had the warrning, but finally it turned into a FATAL ERROR: MarkCompactCollector: semi-space copy, fallback in old gen Allocation failed - JavaScript heap out of memory. the reason was that i dynamically imported the current module, so this ended up with an endless loop...

If your team uses descriptive commit messages (eg. "Ticket #12345 - Update dependencies") on this project, then generating changelog since the latest tag can de done like this:

git log --no-merges --pretty=format:"%s" 'old-tag^'...new-tag > /path/to/changelog.md

• --no-merges omits the merge commits from the list
• old-tag^ refers to the previous commit earlier than the tagged one. Useful if you want to see the tagged commit at the bottom of the list by any reason. (Single quotes needed only for iTerm on mac OS).

Serialization means persisting objects in java. If you want to save the state of the object and want to rebuild the state later (may be in another JVM) serialization can be used.

Note that the properties of an object is only going to be saved. If you want to resurrect the object again you should have the class file, because the member variables only will be stored and not the member functions.

eg:

ObjectInputStream oos = new ObjectInputStream(                                 
                                 new FileInputStream(  new File("o.ser")) ) ;
SerializationSample SS = (SearializationSample) oos.readObject();

The Searializable is a marker interface which marks that your class is serializable. Marker interface means that it is just an empty interface and using that interface will notify the JVM that this class can be made serializable.

Below is the link that suggests how to design Splash screen. To avoid white/black background we need to define a theme with splash background and set that theme to splash in manifest file.

https://android.jlelse.eu/right-way-to-create-splash-screen-on-android-e7f1709ba154

splash_background.xml inside res/drawable folder

<?xml version=”1.0" encoding=”utf-8"?>
 <layer-list xmlns:android=”http://schemas.android.com/apk/res/android">

 <item android:drawable=”@color/colorPrimary” />

 <item>
 <bitmap
 android:gravity=”center”
 android:src=”@mipmap/ic_launcher” />
 </item>

</layer-list>

Add below styles

<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    <!-- Splash Screen theme. -->
    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/splash_background</item>
    </style>

In Manifest set theme as shown below

<activity
            android:name=".SplashActivity"
            android:theme="@style/SplashTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
    </activity>

This wikipedia article has an example in C.

A good example is that new modules written to augment the Apache Web server register with the main apache process by passing them function pointers so those functions are called back to process web page requests.

Add a column called r with type serial. Index r.

Assume we have 200,000 rows, we are going to generate a random number n, where 0 < n <= 200, 000.

Select rows with r > n, sort them ASC and select the smallest one.

Code:

select * from YOUR_TABLE 
where r > (
    select (
        select reltuples::bigint AS estimate
        from   pg_class
        where  oid = 'public.YOUR_TABLE'::regclass) * random()
    )
order by r asc limit(1);

The code is self-explanatory. The subquery in the middle is used to quickly estimate the table row counts from https://stackoverflow.com/a/7945274/1271094 .

In application level you need to execute the statement again if n > the number of rows or need to select multiple rows.

Simple code to redirect page

<!-- html button designing and calling the event in javascript -->
<input id="btntest" type="button" value="Check" 
       onclick="window.location.href = 'http://www.google.com'" />

I set up a simple 3-column range on Sheet1 with Country, City, and Language in columns A, B, and C. The following code autofilters the range and then pastes only one of the columns of autofiltered data to another sheet. You should be able to modify this for your purposes:

Sub CopyPartOfFilteredRange()
    Dim src As Worksheet
    Dim tgt As Worksheet
    Dim filterRange As Range
    Dim copyRange As Range
    Dim lastRow As Long

    Set src = ThisWorkbook.Sheets("Sheet1")
    Set tgt = ThisWorkbook.Sheets("Sheet2")

    ' turn off any autofilters that are already set
    src.AutoFilterMode = False

    ' find the last row with data in column A
    lastRow = src.Range("A" & src.Rows.Count).End(xlUp).Row

    ' the range that we are auto-filtering (all columns)
    Set filterRange = src.Range("A1:C" & lastRow)

    ' the range we want to copy (only columns we want to copy)
    ' in this case we are copying country from column A
    ' we set the range to start in row 2 to prevent copying the header
    Set copyRange = src.Range("A2:A" & lastRow)

    ' filter range based on column B
    filterRange.AutoFilter field:=2, Criteria1:="Rio de Janeiro"

    ' copy the visible cells to our target range
    ' note that you can easily find the last populated row on this sheet
    ' if you don't want to over-write your previous results
    copyRange.SpecialCells(xlCellTypeVisible).Copy tgt.Range("A1")

End Sub

Note that by using the syntax above to copy and paste, nothing is selected or activated (which you should always avoid in Excel VBA) and the clipboard is not used. As a result, Application.CutCopyMode = False is not necessary.

You would use an MvcHtmlString if you want to pass raw HTML to an MVC helper method and you don't want the helper method to encode the HTML.

For the mac, a more similar approach would be this:

find . -name '*.txt' -print0 | xargs -0 sed -i "" "s/form/forms/g"

this.tablenameTableAdapter.Fill(this.databasenameDataSet.tablename)

For a cell to self-reference itself:

INDIRECT(ADDRESS(ROW(), COLUMN()))

For a cell to self-reference its column:

INDIRECT(ADDRESS(1,COLUMN()) & ":" & ADDRESS(65536, COLUMN()))

For a cell to self-reference its row:

INDIRECT(ADDRESS(ROW(),1) & ":" & ADDRESS(ROW(),256))
or
INDIRECT("A" & ROW() & ":IV" & ROW())

The numbers are for 2003 and earlier, use column:XFD and row:1048576 for 2007+.

Note: The INDIRECT function is volatile and should only be used when needed.

As unwind noted, keyword arguments with default values can go a long way.

I'll also state that in my opinion, it goes against the spirit of Python to worry a lot about what types are passed into methods. In Python, I think it's more accepted to use duck typing -- asking what an object can do, rather than what it is.

Thus, if your method may accept a string or a tuple, you might do something like this:

def print_names(names):
    """Takes a space-delimited string or an iterable"""
    try:
        for name in names.split(): # string case
            print name
    except AttributeError:
        for name in names:
            print name

Then you could do either of these:

print_names("Ryan Billy")
print_names(("Ryan", "Billy"))

Although an API like that sometimes indicates a design problem.

There is two condition,

• Use your swift file in objective c file.
• Use your objective c file in swift file.

So, For that purpose, you have to follow this steps:

• Add your swift file in an objective-c project or vice-versa.
• Create header(.h) file.

• Go to Build Settings and perform below steps with search,

  1. search for this text "brid" and set a path of your header file.
  2. "Defines Module": YES.
  3. "Always Embed Swift Standard Libraries" : YES.
  4. "Install Objective-C Compatibility Header" : YES.

After that, clean and rebuild your project.

Use your swift file in objective c file.

In that case,First write "@objc" before your class in swift file.

After that ,In your objective c file, write this,

  #import "YourProjectName-Swift.h"

Use your objective c file in swift file.

In that case, In your header file, write this,

  #import "YourObjective-c_FileName.h"

I hope this will help you.

You have to make the UL inside the div behave like a block. Try adding

.navigation ul {
     display: inline-block;
}

This code will accept all country code with + sign

<input type="text" pattern="[0-9]{5}[-][0-9]{7}[-][0-9]{1}"/>

Some countries allow a single "0" character instead of "+" and others a double "0" character instead of the "+". Neither are standard.

You're looking to create a custom A record.

I'm pretty sure that you can use wildcards when specifying A records which would let you do something like this:

*.mywebsite.com       IN  A       127.0.0.1

127.0.0.1 would be the IP address of your webserver. The method of actually adding the record will depend on your host.

Doing it like http://mywebsite.com/user would be a lot easier to set up if it's an option.

Then you could just add a .htaccess file that looks like this:

Options +FollowSymLinks

RewriteEngine On
RewriteRule ^([aA-zZ])$  dostuff.php?username=$1

In the above, usernames are limited to the characters a-z

The rewrite rule for grabbing the subdomain would look like this:

RewriteCond %{HTTP_HOST} ^(^.*)\.mywebsite.com
RewriteRule (.*)  dostuff.php?username=%1

However, you don't really need any rewrite rules. The HTTP_HOST header is available in PHP as well, so you can get it already, like

$username = strtok($_SERVER['HTTP_HOST'], ".");
