Copy the diff file to the root of your repository, and then do:

git apply yourcoworkers.diff

More information about the apply command is available on its man page.

By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch on the sender and then git am on the receiver, because it also transfers the authorship info and the commit message.

If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3 option of apply that tries to merge in the changes.

It also works with Unix pipe as follows:

git diff d892531 815a3b5 | git apply

You could use smth like this in WPF. I've created example method. Check below.

public string getFolderPath()
{
           // Create OpenFileDialog 
           Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

           OpenFileDialog openFileDialog = new OpenFileDialog();
           openFileDialog.Multiselect = false;

           openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
           if (openFileDialog.ShowDialog() == true)
           {
               System.IO.FileInfo fInfo = new System.IO.FileInfo(openFileDialog.FileName);
               return fInfo.DirectoryName;
           }
           return null;           
       }

n % x == 0

Means that n can be divided by x. So... for instance, in your case:

boolean isDivisibleBy20 = number % 20 == 0;

Also, if you want to check whether a number is even or odd (whether it is divisible by 2 or not), you can use a bitwise operator:

boolean even = (number & 1) == 0;
boolean odd  = (number & 1) != 0;

Java VM contains a single class object per class. Each class may have some shared variables called static variables. If the critical section of the code plays with these variables in a concurrent environment, then we need to make that particular section as synchronized. When there is more than one static synchronized method only one of them will be executed at a time without preemption. That's what lock on class object does.

Try this, perhaps it works ;)

.factory('authInterceptor', function($location, $q, $window) {


return {
    request: function(config) {
      config.headers = config.headers || {};

      config.headers.Authorization = 'xxxx-xxxx';

      return config;
    }
  };
})

.config(function($httpProvider) {
  $httpProvider.interceptors.push('authInterceptor');
})

And make sure your back end works too, try this. I'm using RESTful CodeIgniter.

class App extends REST_Controller {
    var $authorization = null;

    public function __construct()
    {
        parent::__construct();
        header('Access-Control-Allow-Origin: *');
        header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method, Authorization");
        header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
        if ( "OPTIONS" === $_SERVER['REQUEST_METHOD'] ) {
            die();
        }

        if(!$this->input->get_request_header('Authorization')){
            $this->response(null, 400);    
        }

        $this->authorization = $this->input->get_request_header('Authorization');
    }

}

For me it's worked with svn cleanup in Eclipse.

There's no way to evaluate multiple values in one 'case'. You could either use an if statement (as others have suggested) or call a method which evaluates the range that the integer belongs to and returns a value which represents that range (such as "minor", "adult", etc.), then evaluate this returned value in the switch statement. Of course, you'd probably still be using an if statement in the custom method.

Try this:

var control = false;
$(document).on('keyup keydown', function(e) {
  control = e.ctrlKey;
});

$('div#1').on('click', function() {
  if (control) {
    // control-click
  } else {
    // single-click
  }
});

And the right-click triggers a contextmenu event, so:

$('div#1').on('contextmenu', function() {
  // right-click handler
})

I've had good results with this one. Much easier to use than Sharpen.

You can use Enumerable.Intersect:

int[] array1 = new int[] { 1, 2, 3, 4,5 },
      array2 = new int[] {7,8};

if (array1.Intersect(array2).Any())
    Console.WriteLine("matched");
else
    Console.WriteLine("not matched");

You can get to the parent node and then query all the nodes with the class that is being searched. then we get the size

var parent = document.getElementById("parentId");_x000D_
var nodesSameClass = parent.getElementsByClassName("test");_x000D_
console.log(nodesSameClass.length);

<div id="parentId">_x000D_
  <p class="prueba">hello word1</p>_x000D_
  <p class="test">hello word2</p>_x000D_
  <p class="test">hello word3</p>_x000D_
  <p class="test">hello word4</p>_x000D_
</div>

Use ResponseEntity instead of ResponseBody. This way you have access to the response headers and you can set the appropiate content type. According to the Spring docs:

The HttpEntity is similar to @RequestBody and @ResponseBody. Besides getting access to the request and response body, HttpEntity (and the response-specific subclass ResponseEntity) also allows access to the request and response headers

The code will look like:

@RequestMapping(method=RequestMethod.GET, value="/fooBar")
public ResponseEntity<String> fooBar2() {
    String json = "jsonResponse";
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.setContentType(MediaType.APPLICATION_JSON);
    return new ResponseEntity<String>(json, responseHeaders, HttpStatus.CREATED);
}

std::atomic exists because many ISAs have direct hardware support for it

What the C++ standard says about std::atomic has been analyzed in other answers.

So now let's see what std::atomic compiles to to get a different kind of insight.

The main takeaway from this experiment is that modern CPUs have direct support for atomic integer operations, for example the LOCK prefix in x86, and std::atomic basically exists as a portable interface to those intructions: What does the "lock" instruction mean in x86 assembly? In aarch64, LDADD would be used.

This support allows for faster alternatives to more general methods such as std::mutex, which can make more complex multi-instruction sections atomic, at the cost of being slower than std::atomic because std::mutex it makes futex system calls in Linux, which is way slower than the userland instructions emitted by std::atomic, see also: Does std::mutex create a fence?

Let's consider the following multi-threaded program which increments a global variable across multiple threads, with different synchronization mechanisms depending on which preprocessor define is used.

main.cpp

#include <atomic>
#include <iostream>
#include <thread>
#include <vector>

size_t niters;

#if STD_ATOMIC
std::atomic_ulong global(0);
#else
uint64_t global = 0;
#endif

void threadMain() {
    for (size_t i = 0; i < niters; ++i) {
#if LOCK
        __asm__ __volatile__ (
            "lock incq %0;"
            : "+m" (global),
              "+g" (i) // to prevent loop unrolling
            :
            :
        );
#else
        __asm__ __volatile__ (
            ""
            : "+g" (i) // to prevent he loop from being optimized to a single add
            : "g" (global)
            :
        );
        global++;
#endif
    }
}

int main(int argc, char **argv) {
    size_t nthreads;
    if (argc > 1) {
        nthreads = std::stoull(argv[1], NULL, 0);
    } else {
        nthreads = 2;
    }
    if (argc > 2) {
        niters = std::stoull(argv[2], NULL, 0);
    } else {
        niters = 10;
    }
    std::vector<std::thread> threads(nthreads);
    for (size_t i = 0; i < nthreads; ++i)
        threads[i] = std::thread(threadMain);
    for (size_t i = 0; i < nthreads; ++i)
        threads[i].join();
    uint64_t expect = nthreads * niters;
    std::cout << "expect " << expect << std::endl;
    std::cout << "global " << global << std::endl;
}

Conclusions:

• the non-atomic version saves the global to a register, and increments the register.

  Therefore, at the end, very likely four writes happen back to global with the same "wrong" value of 100000.

• std::atomic compiles to lock addq. The LOCK prefix makes the following inc fetch, modify and update memory atomically.

• our explicit inline assembly LOCK prefix compiles to almost the same thing as std::atomic, except that our inc is used instead of add. Not sure why GCC chose add, considering that our INC generated a decoding 1 byte smaller.

ARMv8 could use either LDAXR + STLXR or LDADD in newer CPUs: How do I start threads in plain C?

You can get first element via index selector:

$('div.second div:eq(0)')

Code: http://jsfiddle.net/RX46D/

Don't forget to inject $location into controller.

You can also use a "here document" to do the same thing:

VARIABLE=SOMEVALUE

sqlplus connectioninfo << HERE
start file1.sql
start file2.sql $VARIABLE
quit
HERE

A key is just a normal index. A way over simplification is to think of it like a card catalog at a library. It points MySQL in the right direction.

A unique key is also used for improved searching speed, but it has the constraint that there can be no duplicated items (there are no two x and y where x is not y and x == y).

The manual explains it as follows:

A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. This constraint does not apply to NULL values except for the BDB storage engine. For other engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL. If you specify a prefix value for a column in a UNIQUE index, the column values must be unique within the prefix.

A primary key is a 'special' unique key. It basically is a unique key, except that it's used to identify something.

The manual explains how indexes are used in general: here.

In MSSQL, the concepts are similar. There are indexes, unique constraints and primary keys.

Untested, but I believe the MSSQL equivalent is:

CREATE TABLE tmp (
  id int NOT NULL PRIMARY KEY IDENTITY,
  uid varchar(255) NOT NULL CONSTRAINT uid_unique UNIQUE,
  name varchar(255) NOT NULL,
  tag int NOT NULL DEFAULT 0,
  description varchar(255),
);

CREATE INDEX idx_name ON tmp (name);
CREATE INDEX idx_tag ON tmp (tag);

Edit: the code above is tested to be correct; however, I suspect that there's a much better syntax for doing it. Been a while since I've used SQL server, and apparently I've forgotten quite a bit :).

I'm new to tomcat, and this problem was driving me nuts today. It was sporadic. I asked a colleague to help, and the WAR expanded and it did was it was supposed to. 3 deploys later that day, it reverted back to the original version.

In my case, the MySite.WAR got expanded to both ROOT AND MySite. MySite was usually served up. But sometimes tomcat decided it liked the ROOT one better and all my changes disappeared.

The "solution" is to delete the ROOT website with every deploy of the war.

One thing you need to realize is in Ruby everything is an object. Given that, if you don't define your methods within Module or Class, Ruby will put it within the Object class. So, your code will be local to the Object scope.

A typical approach on Object Oriented Programming is encapsulate all logic within a class:

class Point
  attr_accessor :x, :y

  # If we don't specify coordinates, we start at 0.
  def initialize(x = 0, y = 0)
    # Notice that `@` indicates instance variables.
    @x = x
    @y = y
  end

  # Here we override the `+' operator.
  def +(point)
    Point.new(self.x + point.x, self.y + point.y)
  end

  # Here we draw the point.
  def draw(offset = nil)
    if offset.nil?
      new_point = self
    else
      new_point = self + offset 
    end
    new_point.draw_absolute
  end

  def draw_absolute
    puts "x: #{self.x}, y: #{self.y}"
  end
end

first_point = Point.new(100, 200)
second_point = Point.new(3, 4)

second_point.draw(first_point)

Hope this clarifies a bit.

$(".reset").click(function() {
    $(this).closest('form').find("input[type=text], textarea").val("");
});

In addition to the answer from @WoLpH.

When using the LIKE keyword you also have the ability to limit which direction the string matches. For example:

If you were looking for a string that starts with your $needle:

... WHERE column LIKE '{$needle}%'

If you were looking for a string that ends with the $needle:

... WHERE column LIKE '%{$needle}'

When you have a multi-threaded application, the different threads sometimes share a common resource, such as a variable or similar. This shared source often cannot be accessed at the same time, so a construct is needed to ensure that only one thread is using that resource at a time.

The concept is called "mutual exclusion" (short Mutex), and is a way to ensure that only one thread is allowed inside that area, using that resource etc.

How to use them is language specific, but is often (if not always) based on a operating system mutex.

Some languages doesn't need this construct, due to the paradigm, for example functional programming (Haskell, ML are good examples).

An other solution is to use the response.status function. This will give you the http status wich is returned by the ajax call.

function checkHttpStatus(url) {     
    $.ajax({
        type: "GET",
        data: {},
        url: url,
        error: function(response) {
            alert(url + " returns a " + response.status);
        }, success() {
            alert(url + " Good link");
        }
    });
}

To make a fill completely transparent, fill="transparent" seems to work in modern browsers. But it didn't work in Microsoft Word (for Mac), I had to use fill-opacity="0".

iOS 10 and Swift 3

Assuming that your entity name is "Photo", and that you create a CoreDataStack class...

 func clearData() {
        do {            
            let context = CoreDataStack.sharedInstance.persistentContainer.viewContext
            let fetchRequest = NSFetchRequest<NSFetchRequestResult>(entityName: "Photo")
            do {
                let objects  = try context.fetch(fetchRequest) as? [NSManagedObject]
                _ = objects.map{$0.map{context.delete($0)}}
                CoreDataStack.sharedInstance.saveContext()
            } catch let error {
                print("ERROR DELETING : \(error)")
            }
        }
    }

Here is a good tutorial of how to use CoreData and how to use this method. https://medium.com/compileswift/parsing-json-response-and-save-it-in-coredata-step-by-step-fb58fc6ce16f#.1tu6kt8qb

You can also use a while loop:

while (true) {
    //your code
}

these methods can help setTitle("your new title"); or super("your new title");

In my case, I was integrating Facebook login within a Rails app tutorial. I had added http://localhost:3000/adsf to my Valid OAuth Redirect URIs, but the Rails app would open the url as http://0.0.0.0:3000 and would therefore try to redirect to http://0.0.0.0:3000/asdf. After adding http://0.0.0.0:3000/asdf to the Valid OAuth Redirect URIs, or navigating to http://localhost:3000/asdf, it worked as expected.

You can use this library from JSON.org to translate your string into a JSON object.

var var1_obj = JSON.parse(var1);

Or you can use the jquery-json library as well.

var var1_obj = $.toJSON(var1);

See to get the last digit of any number we divide it by 10 so we either achieve zero or a digit which is placed on last and when we do this continuously we get the whole number as an integer reversed.

    int number=8989,last_num,sum=0;
    while(number>0){
    last_num=number%10; // this will give 8989%10=9
    number/=10;     // now we have 9 in last and now num/ by 10= 898
    sum=sum*10+last_number; //  sum=0*10+9=9;
    }
    // last_num=9.   number= 898. sum=9
    // last_num=8.   number =89.  sum=9*10+8= 98
   // last_num=9.   number=8.    sum=98*10+9=989
   // last_num=8.   number=0.    sum=989*10+8=9898
  // hence completed
   System.out.println("Reverse is"+sum);

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

FILE *fp;
char* str = "string";
int x = 10;

fp=fopen("test.txt", "w");
if(fp == NULL)
    exit(-1);
fprintf(fp, "This is a string which is written to a file\n");
fprintf(fp, "The string has %d words and keyword %s\n", x, str);
fclose(fp);

Element objects have no .getroot() method. Drop that call, and the .tostring() call works:

xmlstr = ElementTree.tostring(et, encoding='utf8', method='xml')

You only need to use .getroot() if you have an ElementTree instance.

Other notes:

• This produces a bytestring, which in Python 3 is the bytes type.
  If you must have a str object, you have two options:

  1. Decode the resulting bytes value, from UTF-8: xmlstr.decode("utf8")

  2. Use encoding='unicode'; this avoids an encode / decode cycle:

     xmlstr = ElementTree.tostring(et, encoding='unicode', method='xml')
     

• If you wanted the UTF-8 encoded bytestring value or are using Python 2, take into account that ElementTree doesn't properly detect utf8 as the standard XML encoding, so it'll add a <?xml version='1.0' encoding='utf8'?> declaration. Use utf-8 or UTF-8 (with a dash) if you want to prevent this. When using encoding="unicode" no declaration header is added.

In My case, I've written below code in build.gradle

android {
// ...
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
// ...

It's work for me!...

The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker command (symbolic link) is not available at /usr/local/bin. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.

1. Install Docker.

   brew cask install docker
   

2. Launch Docker.

   • Press ? + Space to bring up Spotlight Search and enter Docker to launch Docker.
   • In the Docker needs privileged access dialog box, click OK.
   • Enter password and click OK.

   When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker, docker-compose, docker-credential-osxkeychain and docker-machine are created in /usr/local/bin.

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
   

3. Click on the docker whale icon in the status menu and wait for it to show Docker is running.

   

4. Test that docker works fine.

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world
   78445dd45222: Pull complete
   Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash

5. If you are going to use docker-machine to create virtual machines, install VirtualBox.

   brew cask install virtualbox
   

   Note that if VirtualBox is not installed, then docker-machine fails with the following error.

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
   

If you already have axes object, just like in Nick T's answer, you can also use

 ax.patch.set_facecolor('black')

=== checks same sides are equal in type as well as value.

Example:

'1' === 1 // will return "false" because `string` is not a `number`

Common example:

0 == ''  // will be "true", but it's very common to want this check to be "false"

Another common example:

null == undefined // returns "true", but in most cases a distinction is necessary

Many times an untyped check would be handy because you do not care if the value is either undefined, null, 0 or ""

By far the easiest solution (at least in ubuntu/linux):

• make a text file with the urls of the files to download (i.e. file.txt)
• put the 'file.txt' in the directory where you want to download the files
• open the terminal in the download directory from the previous lin
• download the files with the command 'wget -i file.txt'

Works like a charm.

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

In Typescript you need to set types of HTMLAttributes and React.FunctionComponent.

In most cases you will need will be extending it to another interface or type.

const List: React.FunctionComponent<ListProps &
  React.HTMLAttributes<HTMLDivElement>> = (
  props: ListProps & React.HTMLAttributes<HTMLDivElement>
) => {
  return (
    <div className={props.className}>
      <img className="mr-3" src={props.icon} alt="" />
      {props.context}
    </div>
  );
};

interface ListProps {
  context: string;
  icon: string;
}

Try it:

def showDf(df, count=None, percent=None, maxColumns=0):
    if (df == None): return
    import pandas
    from IPython.display import display
    pandas.set_option('display.encoding', 'UTF-8')
    # Pandas dataframe
    dfp = None
    # maxColumns param
    if (maxColumns >= 0):
        if (maxColumns == 0): maxColumns = len(df.columns)
        pandas.set_option('display.max_columns', maxColumns)
    # count param
    if (count == None and percent == None): count = 10 # Default count
    if (count != None):
        count = int(count)
        if (count == 0): count = df.count()
        pandas.set_option('display.max_rows', count)
        dfp = pandas.DataFrame(df.head(count), columns=df.columns)
        display(dfp)
    # percent param
    elif (percent != None):
        percent = float(percent)
        if (percent >=0.0 and percent <= 1.0):
            import datetime
            now = datetime.datetime.now()
            seed = long(now.strftime("%H%M%S"))
            dfs = df.sample(False, percent, seed)
            count = df.count()
            pandas.set_option('display.max_rows', count)
            dfp = dfs.toPandas()    
            display(dfp)

Examples of usages are:

# Shows the ten first rows of the Spark dataframe
showDf(df)
showDf(df, 10)
showDf(df, count=10)

# Shows a random sample which represents 15% of the Spark dataframe
showDf(df, percent=0.15) 

You could define your own extension method, but I wouldn't recommend that.

public static IEnumerable<TResult> SelectNonNull<T, TResult>(this IEnumerable<T> sequence,Func<T, TResult> projection)
{
   return sequence.Select(projection).Where(e => e != null);
}

I don't like this one because it mixes two concerns. Projecting with Select and filtering your null values are separate operations and should not be combined into one method.

I'd rather define an extension method that only checks if the item isn't null:

public static IEnumerable<T> WhereNotNull<T>(this IEnumerable<T> sequence)
{
   return sequence.Where(e => e != null);
}

public static IEnumerable<T> WhereNotNull<T>(this IEnumerable<T?> sequence)
    where T : struct
{
   return sequence.Where(e => e != null).Select(e => e.Value);
}

This has only a single purpose, checking for null. For nullable value types it converts to the non nullable equivalent, since it's useless to preserve the nullable wrapper for values which cannot be null.

With this method, your code becomes:

list.Select(item => item.MyProperty).WhereNotNull()

body{
  margin:0;
  padding:0 0 0 0;
}
div#header{
  position:absolute;
  top:0;
  left:0;
  width:100%;
  height:25;
}
@media screen{
 body>div#header{
   position: fixed;
 }
}
* html body{
  overflow:hidden;
} 
* html div#content{
  height:100%;
  overflow:auto;
}

I needed to print a binary tree in one of my projects, for that I have prepared a java class TreePrinter, one of the sample output is:

                [+]
               /   \
              /     \
             /       \
            /         \
           /           \
        [*]             \
       /   \             [-]
[speed]     [2]         /   \
                    [45]     [12]

Here is the code for class TreePrinter along with class TextNode. For printing any tree you can just create an equivalent tree with TextNode class.

import java.util.ArrayList;

public class TreePrinter {

    public TreePrinter(){
    }

    public static String TreeString(TextNode root){
        ArrayList layers = new ArrayList();
        ArrayList bottom = new ArrayList();

        FillBottom(bottom, root);  DrawEdges(root);

        int height = GetHeight(root);
        for(int i = 0; i  s.length()) min = s.length();

            if(!n.isEdge) s += "[";
            s += n.text;
            if(!n.isEdge) s += "]";

            layers.set(n.depth, s);
        }

        StringBuilder sb = new StringBuilder();

        for(int i = 0; i  temp = new ArrayList();

            for(int i = 0; i  0) temp.get(i-1).left = x;
                temp.add(x);
            }

            temp.get(count-1).left = n.left;
            n.left.depth = temp.get(count-1).depth+1;
            n.left = temp.get(0);

            DrawEdges(temp.get(count-1).left);
        }
        if(n.right != null){
            int count = n.right.x - (n.x + n.text.length() + 2);
            ArrayList temp = new ArrayList();

            for(int i = 0; i  0) temp.get(i-1).right = x;
                temp.add(x);
            }

            temp.get(count-1).right = n.right;
            n.right.depth = temp.get(count-1).depth+1;
            n.right = temp.get(0);  

            DrawEdges(temp.get(count-1).right);
        }
    }

    private static void FillBottom(ArrayList bottom, TextNode n){
        if(n == null) return;

        FillBottom(bottom, n.left);

        if(!bottom.isEmpty()){            
            int i = bottom.size()-1;
            while(bottom.get(i).isEdge) i--;
            TextNode last = bottom.get(i);

            if(!n.isEdge) n.x = last.x + last.text.length() + 3;
        }
        bottom.add(n);
        FillBottom(bottom, n.right);
    }

    private static boolean isLeaf(TextNode n){
        return (n.left == null && n.right == null);
    }

    private static int GetHeight(TextNode n){
        if(n == null) return 0;

        int l = GetHeight(n.left);
        int r = GetHeight(n.right);

        return Math.max(l, r) + 1;
    }
}


class TextNode {
    public String text;
    public TextNode parent, left, right;
    public boolean isEdge;
    public int x, depth;

    public TextNode(String text){
        this.text = text;
        parent = null; left = null; right = null;
        isEdge = false;
        x = 0; depth = 0;
    }
}

Finally here is a test class for printing given sample:

public class Test {

    public static void main(String[] args){
        TextNode root = new TextNode("+");
        root.left = new TextNode("*");            root.left.parent = root;
        root.right = new TextNode("-");           root.right.parent = root;
        root.left.left = new TextNode("speed");   root.left.left.parent = root.left;
        root.left.right = new TextNode("2");      root.left.right.parent = root.left;
        root.right.left = new TextNode("45");     root.right.left.parent = root.right;
        root.right.right = new TextNode("12");    root.right.right.parent = root.right;

        System.out.println(TreePrinter.TreeString(root));
    }
}

You might try this tool: http://fittextjs.com/

I haven't used this second tool, but it seems similar: https://github.com/zachleat/BigText

try something like this :

$.ajax({
    type: 'POST',
    url: 'loginCheck',
    data: $(formLogin).serialize(),
    dataType: 'json',
    success: function (textStatus, status) {
        console.log(textStatus);
        console.log(status);
    },
    error: function(xhr, textStatus, error) {
        console.log(xhr.responseText);
        console.log(xhr.statusText);
        console.log(textStatus);
        console.log(error);
    }
});

It sounds like you need to some background reading on what an FFT is (e.g. http://en.wikipedia.org/wiki/FFT). But to answer your questions:

Why does the x-axis (frequency) end at 500?

Because the input vector is length 1000. In general, the FFT of a length-N input waveform will result in a length-N output vector. If the input waveform is real, then the output will be symmetrical, so the first 501 points are sufficient.

Edit: (I didn't notice that the example padded the time-domain vector.)

The frequency goes to 500 Hz because the time-domain waveform is declared to have a sample-rate of 1 kHz. The Nyquist sampling theorem dictates that a signal with sample-rate fs can support a (real) signal with a maximum bandwidth of fs/2.

How do I know the frequencies are between 0 and 500?

See above.

Shouldn't the FFT tell me, in which limits the frequencies are?

No.

Does the FFT only return the amplitude value without the frequency?

The FFT simply assigns an amplitude (and phase) to every frequency bin.

You have multiple columns named the same thing in your inner query, so the error is raised in the outer query. If you get rid of the outer query, it should run, although still be confusing:

SELECT DISTINCT
    coaches.id,
    people.*,
    users.*,
    coaches.*
FROM "COACHES"
    INNER JOIN people ON people.id = coaches.person_id
    INNER JOIN users ON coaches.person_id = users.person_id
    LEFT OUTER JOIN organizations_users ON organizations_users.user_id = users.id
WHERE
    rownum <= 25

It would be much better (for readability and performance both) to specify exactly what fields you need from each of the tables instead of selecting them all anyways. Then if you really need two fields called the same thing from different tables, use column aliases to differentiate between them.

I recommend you to checkout @angular-material-components/datetime-picker. This is a DatetimePicker like @angular/material Datepicker by adding support for choosing time.

Add this for pages not currently on your site...

ErrorDocument 404 http://example.com/

Along with your Redirect 301 / http://www.thenewdomain.com/ that should cover all the bases...

Good luck!

<a href="1.html"><input type="text" class="button_active" value="1"></a>
<a href="2.html"><input type="text" class="button" value="2"></a>
<a href="3.html"><input type="text" class="button" value="3"></a>

Try that. Unless you truly need to stick with the type as submit, then what I provided should work. If you are going to stick with submit, then everything mentioned above is correct, it makes no sense.

you can use siblings and removeClass method

$('.nav-link li').click(function() {
    $(this).addClass('active').siblings().removeClass('active');
});

Provisioning files are located in:

/Users/${USER}/Library/MobileDevice/Provisioning Profiles/

Just remove the out-of-date files.

You need to do a while loop to get the result from the SQL query, like this:

require_once('db.php');  
$sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )    
FROM modul1open) ORDER BY idM1O LIMIT 1";

$result = mysql_query($sql);

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

    // If you want to display all results from the query at once:
    print_r($row);

    // If you want to display the results one by one
    echo $row['column1'];
    echo $row['column2']; // etc..

}

Also I would strongly recommend not using mysql_* since it's deprecated. Instead use the mysqli or PDO extension. You can read more about that here.

Alternately, you could do a Text to Columns with space as the delimiter.

calling async in constructor maybe cause deadlock, please refer to http://social.msdn.microsoft.com/Forums/en/winappswithcsharp/thread/0d24419e-36ad-4157-abb5-3d9e6c5dacf1

Use permission symbols instead of numbers

Your problem would have been avoided if you had used the more semantically named permission symbols rather than raw magic numbers, e.g. for 664:

#!/usr/bin/env python3

import os
import stat

os.chmod(
    'myfile',
    stat.S_IRUSR |
    stat.S_IWUSR |
    stat.S_IRGRP |
    stat.S_IWGRP |
    stat.S_IROTH
)

This is documented at https://docs.python.org/3/library/os.html#os.chmod and the names are the same as the POSIX C API values documented at man 2 stat.

Another advantage is the greater portability as mentioned in the docs:

Note: Although Windows supports chmod(), you can only set the file’s read-only flag with it (via the stat.S_IWRITE and stat.S_IREAD constants or a corresponding integer value). All other bits are ignored.

chmod +x is demonstrated at: How do you do a simple "chmod +x" from within python?

Tested in Ubuntu 16.04, Python 3.5.2.

Improved code to return the duplicate elements

• Can find duplicates in a Collection
• return the set of duplicates
• Unique Elements can be obtained from the Set

public static <T> List getDuplicate(Collection<T> list) {

    final List<T> duplicatedObjects = new ArrayList<T>();
    Set<T> set = new HashSet<T>() {
    @Override
    public boolean add(T e) {
        if (contains(e)) {
            duplicatedObjects.add(e);
        }
        return super.add(e);
    }
    };
   for (T t : list) {
        set.add(t);
    }
    return duplicatedObjects;
}


public static <T> boolean hasDuplicate(Collection<T> list) {
    if (getDuplicate(list).isEmpty())
        return false;
    return true;
}

function truncate ($str, $length) {
    if (strlen($str) > $length) {
        $str = substr($str, 0, $length+1);
        $pos = strrpos($str, ' ');
        $str = substr($str, 0, ($pos > 0)? $pos : $length);
    }
    return $str;
}

Example:

print truncate('The first step to eternal life is you have to die.', 25);

string(25) "The first step to eternal"

print truncate('The first step to eternal life is you have to die.', 12);

string(9) "The first"

print truncate('FirstStepToEternalLife', 5);

string(5) "First"

Java 8 Had changed the world you can have static methods in interface but it forces you to provide implementation for that.

public interface StaticMethodInterface {
public static int testStaticMethod() {
    return 0;
}

/**
 * Illegal combination of modifiers for the interface method
 * testStaticMethod; only one of abstract, default, or static permitted
 * 
 * @param i
 * @return
 */
// public static abstract int testStaticMethod(float i);

default int testNonStaticMethod() {
    return 1;
}

/**
 * Without implementation.
 * 
 * @param i
 * @return
 */
int testNonStaticMethod(float i);

}

I wrote this a long time ago (from years 1985-1992, with just a few tweaks since then), and just copy and paste the bits needed into each project.

You must call cfmakeraw on a tty obtained from tcgetattr. You cannot zero-out a struct termios, configure it, and then set the tty with tcsetattr. If you use the zero-out method, then you will experience unexplained intermittent failures, especially on the BSDs and OS X. "Unexplained intermittent failures" include hanging in read(3).

#include <errno.h>
#include <fcntl.h>

char buf [100];
int n = read (fd, buf, sizeof buf);  // read up to 100 characters if ready to read

The values for speed are B115200, B230400, B9600, B19200, B38400, B57600, B1200, B2400, B4800, etc. The values for parity are 0 (meaning no parity), PARENB|PARODD (enable parity and use odd), PARENB (enable parity and use even), PARENB|PARODD|CMSPAR (mark parity), and PARENB|CMSPAR (space parity).

"Blocking" sets whether a read() on the port waits for the specified number of characters to arrive. Setting no blocking means that a read() returns however many characters are available without waiting for more, up to the buffer limit.

Addendum:

CMSPAR is needed only for choosing mark and space parity, which is uncommon. For most applications, it can be omitted. My header file /usr/include/bits/termios.h enables definition of CMSPAR only if the preprocessor symbol __USE_MISC is defined. That definition occurs (in features.h) with

#if defined _BSD_SOURCE || defined _SVID_SOURCE
 #define __USE_MISC     1
#endif

The introductory comments of <features.h> says:

/* These are defined by the user (or the compiler)
   to specify the desired environment:

...
   _BSD_SOURCE          ISO C, POSIX, and 4.3BSD things.
   _SVID_SOURCE         ISO C, POSIX, and SVID things.
...

I just had the same problem, what I did, I arranged the library order in sequence, for example there were java.lang.NullPointerException and javacard.lang.NullPointerException. I made the first one as default library and if you needed to use the other you can explicitly specify the full qualified class name.

I found this https://typescriptbcl.codeplex.com/SourceControl/latest

here is the Guid version they have in case the link does not work later.

module System {
    export class Guid {
        constructor (public guid: string) {
            this._guid = guid;
        }

        private _guid: string;

        public ToString(): string {
            return this.guid;
        }

        // Static member
        static MakeNew(): Guid {
            var result: string;
            var i: string;
            var j: number;

            result = "";
            for (j = 0; j < 32; j++) {
                if (j == 8 || j == 12 || j == 16 || j == 20)
                    result = result + '-';
                i = Math.floor(Math.random() * 16).toString(16).toUpperCase();
                result = result + i;
            }
            return new Guid(result);
        }
    }
}

We managed to fix in the end:

/*menu handler*/
$(function(){
  function stripTrailingSlash(str) {
    if(str.substr(-1) == '/') {
      return str.substr(0, str.length - 1);
    }
    return str;
  }

  var url = window.location.pathname;  
  var activePage = stripTrailingSlash(url);

  $('.nav li a').each(function(){  
    var currentPage = stripTrailingSlash($(this).attr('href'));

    if (activePage == currentPage) {
      $(this).parent().addClass('active'); 
    } 
  });
});

UPDATE:

onActivityCreated() is deprecated from API Level 28.

onCreate():

The onCreate() method in a Fragment is called after the Activity's onAttachFragment() but before that Fragment's onCreateView().
In this method, you can assign variables, get Intent extras, and anything else that doesn't involve the View hierarchy (i.e. non-graphical initialisations). This is because this method can be called when the Activity's onCreate() is not finished, and so trying to access the View hierarchy here may result in a crash.

onCreateView():

After the onCreate() is called (in the Fragment), the Fragment's onCreateView() is called. You can assign your View variables and do any graphical initialisations. You are expected to return a View from this method, and this is the main UI view, but if your Fragment does not use any layouts or graphics, you can return null (happens by default if you don't override).

onActivityCreated():

As the name states, this is called after the Activity's onCreate() has completed. It is called after onCreateView(), and is mainly used for final initialisations (for example, modifying UI elements). This is deprecated from API level 28.

To sum up...
... they are all called in the Fragment but are called at different times.
The onCreate() is called first, for doing any non-graphical initialisations. Next, you can assign and declare any View variables you want to use in onCreateView(). Afterwards, use onActivityCreated() to do any final initialisations you want to do once everything has completed.

If you want to view the official Android documentation, it can be found here:

• onCreate()
• onCreateView()
• onActivityCreated()_

There are also some slightly different, but less developed questions/answers here on Stack Overflow:

• onCreate() vs onCreateView()
• onCreateView() vs onActivityCreated()

I think the problem is given in the error message, although it is not very easy to spot:

IndexError: too many indices for array
xs  = data[:, col["l1"     ]]

'Too many indices' means you've given too many index values. You've given 2 values as you're expecting data to be a 2D array. Numpy is complaining because data is not 2D (it's either 1D or None).

This is a bit of a guess - I wonder if one of the filenames you pass to loadfile() points to an empty file, or a badly formatted one? If so, you might get an array returned that is either 1D, or even empty (np.array(None) does not throw an Error, so you would never know...). If you want to guard against this failure, you can insert some error checking into your loadfile function.

I highly recommend in your for loop inserting:

print(data)

This will work in Python 2.x or 3.x and might reveal the source of the issue. You might well find it is only one value of your outputs_l1 list (i.e. one file) that is giving the issue.

AFAIK there isn't a built-in mechanism in Eclipse for this.

The closest you can get is to create a wrapper that prompts you for these values and invokes the (hardcoded) main. You then get you execution history as long as you don't clear terminated processes. Two variations on this are either to use JUNit, or to use injection or parameter so that your wrapper always connects to the correct class for its main.

If it does not work for you, run the command with sudo.

Since nobody so far felt fit to point out why what you're trying doesn't work:

1. NA == NA doesn't return TRUE, it returns NA (since comparing to undefined values should yield an undefined result).
2. You're trying to call apply on an atomic vector. You can't use apply to loop over the elements in a column.
3. Your subscripts are off - you're trying to give two indices into a$x, which is just the column (an atomic vector).

I'd fix up 3. to get to a$x[is.na(a$x)] <- 0

FTP protocol may be blocked by your ISP firewall, try connecting via SFTP (i.e. use 22 for port num instead of 21 which is simply FTP).

"All I want to do is join the tables and then group all the employees in a particular location together."

It sounds like what you want is for the output of the SQL statement to list every employee in the company, but first all the people in the Anaheim office, then the people in the Buffalo office, then the people in the Cleveland office (A, B, C, get it, obviously I don't know what locations you have).

In that case, lose the GROUP BY statement. All you need is ORDER BY loc.LocationID

Why not use the jQuery Event API?

http://learn.jquery.com/events/event-extensions/

I've used this simple event with success. It's clean, namespaceable and flexible enough to improve upon.

var isMobile = /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent);
var eventType = isMobile ? "touchstart" : "click";

jQuery.event.special.touchclick = {
  bindType: eventType,
  delegateType: eventType
};

Step 1: Stop MySQL daemon if it is currently running

  ps -ef | grep mysql      - checks if mysql/mysqld is one of the running processes.

  pkill mysqld             - kills the daemon, if it is running.

Step 2: Run MySQL safe daemon with skipping grant tables

  mysqld_safe --skip-grant-tables &

  mysql -u root mysql

Step 3: Login to MySQL as root with no password

  mysql -u root mysql

Step 4: Run UPDATE query to reset the root password

  UPDATE user SET password=PASSWORD("value=42") WHERE user="root";
  FLUSH PRIVILEGES;

In MySQL 5.7, the 'password' field was removed, now the field name is 'authentication_string':

  UPDATE user SET authentication_string=PASSWORD("42") WHERE 
  user="root";
  FLUSH PRIVILEGES;

Step 5: Stop MySQL safe daemon

Step 6: Start MySQL daemon

The Matlab Compiler is the standard way to do this. mcc is the command. The Matlab Runtime is required to run the programs; I'm not sure if it can be directly integrated with the executable or not.

Since pandas 0.22 update, comparison options are available like:

• gt (greater than)
• lt (lesser than)
• eq (equals to)
• ne (not equals to)
• ge (greater than or equals to)

and many more. These functions return boolean array. Let's see how we can use them:

# sample data
df = pd.DataFrame({'col1': [0, 1, 2,3,4,5], 'col2': [10, 11, 12,13,14,15]})

# get values from col1 greater than or equals to 1
df.loc[df['col1'].ge(1),'col1']

1    1
2    2
3    3
4    4
5    5

# where co11 values is better 0 and 2
df.loc[df['col1'].between(0,2)]

 col1 col2
0   0   10
1   1   11
2   2   12

# where col1 > 1
df.loc[df['col1'].gt(1)]

 col1 col2
2   2   12
3   3   13
4   4   14
5   5   15

I had written this program in java. I think this might also help:

public class Anagram {
    public static void main(String[] args) {
        checkAnagram("listen", "silent");
    }

    public static void checkAnagram(String str1, String str2) {
        boolean isAnagram = false;
        str1 = sortStr(str1);
        str2 = sortStr(str2);
        if (str1.equals(str2)) {
            isAnagram = true;
        }
        if (isAnagram) {
            System.out.println("Two strings are anagram");
        } else {
            System.out.println("Two string are not anagram");
        }

    }

    public static String sortStr(String str) {
        char[] strArr = str.toCharArray();
        for (int i = 0; i < str.length(); i++) {
            for (int j = i + 1; j < str.length(); j++) {
                if (strArr[i] > strArr[j]) {
                    char temp = strArr[i];
                    strArr[i] = strArr[j];
                    strArr[j] = temp;
                }
            }
        }
        String output = String.valueOf(strArr);
        return output;
    }
}

Using Python's built in range function:

Python 2

input = 8
output = range(input + 1)

print output
[0, 1, 2, 3, 4, 5, 6, 7, 8]

Python 3

input = 8
output = list(range(input + 1))

print(output)
[0, 1, 2, 3, 4, 5, 6, 7, 8]

I don't use named parameters for all queries. For example it is unusual to use named parameters in JpaRepository.

To workaround I use JPQL CONCAT function (this code emulate start with):

@Repository
public interface BranchRepository extends JpaRepository<Branch, String> {
    private static final String QUERY = "select b from Branch b"
       + " left join b.filial f"
       + " where f.id = ?1 and b.id like CONCAT(?2, '%')";
    @Query(QUERY)
    List<Branch> findByFilialAndBranchLike(String filialId, String branchCode);
}

I found this technique in excellent docs: http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/manual/jpa_overview_query.html

You can do it using remote debugging, here is official documentation. Basic process:

1. Connect your android device
2. Select your device: More tools > Inspect devices* from dev tools on pc/mac.
3. Authorize on your mobile.
4. Happy debugging!!

* This is now "Remote devices".

In a single line of code:

bool bVal = Convert.ToBoolean(Convert.ToInt16(returnValue))

See Redirecting Output from a Running Process.

Firstly I run the command cat > foo1 in one session and test that data from stdin is copied to the file. Then in another session I redirect the output.

Firstly find the PID of the process:

$ ps aux | grep cat
rjc 6760 0.0 0.0 1580 376 pts/5 S+ 15:31 0:00 cat

Now check the file handles it has open:

$ ls -l /proc/6760/fd
total 3
lrwx—— 1 rjc rjc 64 Feb 27 15:32 0 -> /dev/pts/5
l-wx—— 1 rjc rjc 64 Feb 27 15:32 1 -> /tmp/foo1
lrwx—— 1 rjc rjc 64 Feb 27 15:32 2 -> /dev/pts/5

Now run GDB:

$ gdb -p 6760 /bin/cat
GNU gdb 6.4.90-debian

[license stuff snipped]

Attaching to program: /bin/cat, process 6760

[snip other stuff that's not interesting now]

(gdb) p close(1)
$1 = 0
(gdb) p creat("/tmp/foo3", 0600)
$2 = 1
(gdb) q
The program is running. Quit anyway (and detach it)? (y or n) y
Detaching from program: /bin/cat, process 6760

The p command in GDB will print the value of an expression, an expression can be a function to call, it can be a system call… So I execute a close() system call and pass file handle 1, then I execute a creat() system call to open a new file. The result of the creat() was 1 which means that it replaced the previous file handle. If I wanted to use the same file for stdout and stderr or if I wanted to replace a file handle with some other number then I would need to call the dup2() system call to achieve that result.

For this example I chose to use creat() instead of open() because there are fewer parameter. The C macros for the flags are not usable from GDB (it doesn’t use C headers) so I would have to read header files to discover this – it’s not that hard to do so but would take more time. Note that 0600 is the octal permission for the owner having read/write access and the group and others having no access. It would also work to use 0 for that parameter and run chmod on the file later on.

After that I verify the result:

ls -l /proc/6760/fd/
total 3
lrwx—— 1 rjc rjc 64 2008-02-27 15:32 0 -> /dev/pts/5
l-wx—— 1 rjc rjc 64 2008-02-27 15:32 1 -> /tmp/foo3 <====
lrwx—— 1 rjc rjc 64 2008-02-27 15:32 2 -> /dev/pts/5

Typing more data in to cat results in the file /tmp/foo3 being appended to.

If you want to close the original session you need to close all file handles for it, open a new device that can be the controlling tty, and then call setsid().

It is because you forgot to pass in event into the click function:

$('.menuOption').on('click', function (e) { // <-- the "e" for event

    e.preventDefault(); // now it'll work

    var categories = $(this).attr('rel');
    $('.pages').hide();
    $(categories).fadeIn();
});

On a side note, e is more commonly used as opposed to the word event since Event is a global variable in most browsers.

If your exe takes arguments,

start MyApp.exe -arg1 -arg2

You can't search a text field without converting it from text to varchar.

declare @table table (a text)
insert into @table values ('a')
insert into @table values ('a')
insert into @table values ('b')
insert into @table values ('c')
insert into @table values ('d')


select *
from @table
where a ='a'

This give an error:

The data types text and varchar are incompatible in the equal to operator.

Wheras this does not:

declare @table table (a varchar(max))

Interestingly, LIKE still works, i.e.

where a like '%a%'

autocomplete="off" this should fix the issue for all modern browsers.

<form name="form1" id="form1" method="post" autocomplete="off"
   action="http://www.example.com/form.cgi">
  [...]
</form>

In current versions of Gecko browsers, the autocomplete attribute works perfectly. For earlier versions, going back to Netscape 6.2, it worked with the exception for forms with "Address" and "Name"

Update

In some cases, the browser will keep suggesting autocompletion values even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really forcing the no-autocompletion is to assign a random string to the attribute, for example:

autocomplete="nope"

Though there are so many good answers, here is my two cents for the future me :P and for anyone who wants it quick and easy.

For Mac:

• connect the device using USB first and make sure debugging is working. Disconnect any other devices and quit emulators.

• open terminal and run the following script

  adb tcpip 5555
  adb connect $(adb shell ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{print $2}' | cut -d: -f2):5555
  

• disconnect USB connection and the device should be available for WiFi debugging

Explanation:

adb tcpip 5555 commands the device to start listening for connections on port 5555

adb connect $(_ip_address_fetched_):5555 tells to connect on port 5555 of the _ip_address_fetched_ address

where _ip_address_fetched_ includes following:

adb shell ifconfig getting internet configurations using adb shell

grep "inter " filter any line that starts with inter

grep -v 127.0.0.1 exclude localhost.

At this point, output should be like:

inet addr:###.###.#.### Bcast:###.###.#.### Mask:255.255.255.0

awk '{print $2}' get the second part of the components array, separated by space (I'm using zsh).

The output up to this point is

addr:###.###.#.###

cut -d: -f2 split the string by delimiter : and take second part. It will only take your device IP address

A bit late here, but none of the above seemed to work. Try this, using printf, inserts spaces between each. I chose to not have newline at the end.

awk '{for(i=3;i<=NF;++i) printf("%s ",  $i) }'

I updated the example from airmind supporting tags for foreground and background. Just use the color variables $BLACK - $WHITE in your log formatter string. To set the background just use $BG-BLACK - $BG-WHITE.

import logging

BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE = range(8)

COLORS = {
    'WARNING'  : YELLOW,
    'INFO'     : WHITE,
    'DEBUG'    : BLUE,
    'CRITICAL' : YELLOW,
    'ERROR'    : RED,
    'RED'      : RED,
    'GREEN'    : GREEN,
    'YELLOW'   : YELLOW,
    'BLUE'     : BLUE,
    'MAGENTA'  : MAGENTA,
    'CYAN'     : CYAN,
    'WHITE'    : WHITE,
}

RESET_SEQ = "\033[0m"
COLOR_SEQ = "\033[1;%dm"
BOLD_SEQ  = "\033[1m"

class ColorFormatter(logging.Formatter):

    def __init__(self, *args, **kwargs):
        # can't do super(...) here because Formatter is an old school class
        logging.Formatter.__init__(self, *args, **kwargs)

    def format(self, record):
        levelname = record.levelname
        color     = COLOR_SEQ % (30 + COLORS[levelname])
        message   = logging.Formatter.format(self, record)
        message   = message.replace("$RESET", RESET_SEQ)\
                           .replace("$BOLD",  BOLD_SEQ)\
                           .replace("$COLOR", color)
        for k,v in COLORS.items():
            message = message.replace("$" + k,    COLOR_SEQ % (v+30))\
                             .replace("$BG" + k,  COLOR_SEQ % (v+40))\
                             .replace("$BG-" + k, COLOR_SEQ % (v+40))
        return message + RESET_SEQ

logging.ColorFormatter = ColorFormatter

So now you can simple do the following in your config file:

[formatter_colorFormatter]
class=logging.ColorFormatter
format= $COLOR%(levelname)s $RESET %(asctime)s $BOLD$COLOR%(name)s$RESET %(message)s

Assuming your sm_id and c_id properties are public, you can access them by using a foreach on the array:

$array = array(/* objects in an array here */);
foreach ($array as $obj) {
    echo $obj->sm_id . '<br />' . $obj->c_id . '<br />';
}

As stated on w3schools:

audio/* - All sound files are accepted

video/* - All video files are accepted

image/* - All image files are accepted

MIME_type - A valid MIME type, with no parameters. Look at IANA MIME types for a complete list of standard MIME types

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

I was looking for a solution to quite a related problem: finding the newest records per group which is a specialization of a typical greatest-n-per-group with N = 1.

The solution involves the problem you are dealing with here (i.e., how to build the query in Eloquent) so I am posting it as it might be helpful for others. It demonstrates a cleaner way of sub-query construction using powerful Eloquent fluent interface with multiple join columns and where condition inside joined sub-select.

In my example I want to fetch the newest DNS scan results (table scan_dns) per group identified by watch_id. I build the sub-query separately.

The SQL I want Eloquent to generate:

SELECT * FROM `scan_dns` AS `s`
INNER JOIN (
  SELECT x.watch_id, MAX(x.last_scan_at) as last_scan
  FROM `scan_dns` AS `x`
  WHERE `x`.`watch_id` IN (1,2,3,4,5,42)
  GROUP BY `x`.`watch_id`) AS ss
ON `s`.`watch_id` = `ss`.`watch_id` AND `s`.`last_scan_at` = `ss`.`last_scan`

I did it in the following way:

// table name of the model
$dnsTable = (new DnsResult())->getTable();

// groups to select in sub-query
$ids = collect([1,2,3,4,5,42]);

// sub-select to be joined on
$subq = DnsResult::query()
    ->select('x.watch_id')
    ->selectRaw('MAX(x.last_scan_at) as last_scan')
    ->from($dnsTable . ' AS x')
    ->whereIn('x.watch_id', $ids)
    ->groupBy('x.watch_id');
$qqSql = $subq->toSql();  // compiles to SQL

// the main query
$q = DnsResult::query()
    ->from($dnsTable . ' AS s')
    ->join(
        DB::raw('(' . $qqSql. ') AS ss'),
        function(JoinClause $join) use ($subq) {
            $join->on('s.watch_id', '=', 'ss.watch_id')
                 ->on('s.last_scan_at', '=', 'ss.last_scan')
                 ->addBinding($subq->getBindings());  
                 // bindings for sub-query WHERE added
        });

$results = $q->get();

UPDATE:

Since Laravel 5.6.17 the sub-query joins were added so there is a native way to build the query.

$latestPosts = DB::table('posts')
                   ->select('user_id', DB::raw('MAX(created_at) as last_post_created_at'))
                   ->where('is_published', true)
                   ->groupBy('user_id');

$users = DB::table('users')
        ->joinSub($latestPosts, 'latest_posts', function ($join) {
            $join->on('users.id', '=', 'latest_posts.user_id');
        })->get();

Using the momentjs library, this can be achieved with the startOf() and endOf() methods on the moment's current date object, passing the string 'day' as arguments:

Local GMT:

var start = moment().startOf('day'); // set to 12:00 am today
var end = moment().endOf('day'); // set to 23:59 pm today

For UTC:

var start = moment.utc().startOf('day'); 
var end = moment.utc().endOf('day'); 

I used above proposals and created a kotlin version for our question. Hope this provides some additional help for those using kotlin:

private val screenDimensions: Int by lazy {
    val display = (context.getSystemService(Context.WINDOW_SERVICE) as WindowManager).defaultDisplay
    Point()
        .also { size ->
            when {
                Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1 -> display.getRealSize(size)
                else -> display.getSize(size)
            }
        }
}

screenDimensions.x // width
screenDimensions.y // height

from manual:

: [arguments] No effect; the command does nothing beyond expanding arguments and performing any specified redirections. A zero exit code is returned.

As this returns always zero therefore is is similar to be used as true

Check out this answer: What Is the Purpose of the `:' (colon) GNU Bash Builtin?

execute below

Python manage.py makemigrations

It will show missing package.

Install missing package and again run below command to make sure if nothing is missed.

It will resolve your issue.

You can do this using $lookup aggregation as well and probably the best way as now populate is becoming extinct from the mongo

Project.aggregate([
  { "$match": { "_id": mongoose.Types.ObjectId(id) } },
  { "$lookup": {
    "from": Pages.collection.name,
    "let": { "pages": "$pages" },
    "pipeline": [
      { "$match": { "$expr": { "$in": [ "$_id", "$$pages" ] } } },
      { "$lookup": {
        "from": Component.collection.name,
        "let": { "components": "$components" },
        "pipeline": [
          { "$match": { "$expr": { "$in": [ "$_id", "$$components" ] } } },
        ],
        "as": "components"
      }},
    ],
    "as": "pages"
  }}
])

I would prefer a callback solution: Working fiddle here: http://jsfiddle.net/canCu/

function myFunction(value1,value2,value3, callback) {

    value2 = 'somevalue2'; //to return
    value3 = 'somevalue3'; //to return

    callback( value2, value3 );

}

var value1 = 1;
var value2 = 2;
var value3 = 3;

myFunction(value1,value2,value3, function(value2, value3){
    if (value2 && value3) {
        //Do some stuff
        alert( value2 + '-' + value3 );
    }    
});

Try

if (!(i == 'InvKey' || i == 'PostDate')) {

or

if (i != 'InvKey' || i != 'PostDate') {

that says if i does not equals InvKey OR PostDate

I think the easiest from a logical and efficiency point of view is using the queryset's exists() function, documented here:

https://docs.djangoproject.com/en/stable/ref/models/querysets/#django.db.models.query.QuerySet.exists

So in your example above I would simply write:

if User.objects.filter(email = cleaned_info['username']).exists():
    # at least one object satisfying query exists
else:
    # no object satisfying query exists

Many people prefer to use just .keep since the convention has nothing to do with git.

In JavaScript, null is a special singleton object which is helpful for signaling "no value". You can test for it by comparison and, as usual in JavaScript, it's a good practice to use the === operator to avoid confusing type coercion:

var a = null;
alert(a === null); // true

As @rynah mentions, "undefined" is a bit confusing in JavaScript. However, it's always safe to test if the typeof(x) is the string "undefined", even if "x" is not a declared variable:

alert(typeof(x) === 'undefined'); // true

Also, variables can have the "undefined value" if they are not initialized:

var y;
alert(typeof(y) === 'undefined'); // true

Putting it all together, your check should look like this:

if ((typeof(data) !== 'undefined') && (data !== null)) {
  // ...

However, since the variable "data" is always defined since it is a formal function parameter, using the "typeof" operator is unnecessary and you can safely compare directly with the "undefined value".

function(data) {
  if ((data !== undefined) && (data !== null)) {
    // ...

This snippet amounts to saying "if the function was called with an argument which is defined and is not null..."

Since Spring 3.0, you can add a line like

<bean id="conversionService" 
    class="org.springframework.context.support.ConversionServiceFactoryBean" />

to your applicationContext.xml (or where you configure things). As Dmitry Chornyi points out in a comment, Java based configuration looks like:

@Bean public ConversionService conversionService() {
    return new DefaultConversionService();
}

This activates the new configuration service which supports converting String to Collection types. If you do not activate this configuration service, Spring falls back on its legacy property editors as configuration services, which do not support this kind of conversion.

Converting to collections of other types works, too:

@Value("${my.list.of.ints}")
private List<Integer> myList

will work with a line like

 my.list.of.ints= 1, 2, 3, 4

No problems with whitespace there, the ConversionServiceFactoryBean takes care of it.

See http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#core-convert-Spring-config

In a Spring application, you typically configure a ConversionService instance per Spring container (or ApplicationContext). That ConversionService will be picked up by Spring and then used whenever a type conversion needs to be performed by the framework. [...] If no ConversionService is registered with Spring, the original PropertyEditor-based system is used.

You should use font-size for controlling the height, it is widely supported amongst browsers. And in order to add spacing, you should use padding. Forexample,

.inputField{
  font-size: 30px;
  padding-top: 10px;
  padding-bottom: 10px;
}

Simply put a file named favicon.ico in the webroot.

You have to read the API carefully for this methods. Sometimes you can get confused very easily.

It is either:

if (B.class.isInstance(view))

API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)

or:

if (B.class.isAssignableFrom(view.getClass()))

API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter

or (without reflection and the recommended one):

if (view instanceof B)

A StringBuilder will help you when you need to build strings in multiple steps.

Instead of doing this:

String x = "";
x += "first ";
x += "second ";
x += "third ";

you do

StringBuilder sb = new StringBuilder("");
sb.Append("first ");
sb.Append("second ");
sb.Append("third");
String x = sb.ToString();

The final effect is the same, but the StringBuilder will use less memory and will run faster. Instead of creating a new string which is the concatenation of the two, it will create the chunks separately, and only at the end it will unite them.

Setting the underlying socket ReceiveTimeout property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout. You can read the docs for more information.

Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.

I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  var bytes = 0;
  client.Client.ReceiveTimeout = 20;
  do
  {
      try
      {
          bytes = stm.Read(resp, 0, resp.Length);
          memStream.Write(resp, 0, bytes);
      }
      catch (IOException ex)
      {
          // if the ReceiveTimeout is reached an IOException will be raised...
          // with an InnerException of type SocketException and ErrorCode 10060
          var socketExept = ex.InnerException as SocketException;
          if (socketExept == null || socketExept.ErrorCode != 10060)
              // if it's not the "expected" exception, let's not hide the error
              throw ex;
          // if it is the receive timeout, then reading ended
          bytes = 0;
      }
  } while (bytes > 0);
  return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

The above solutions didn't work for me. But I found this that worked:

sudo apt-get update -y && sudo apt-get install -y python3-pip python3-dev
sudo apt-get remove docker docker-engine docker.io
curl -fsSL get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo pip3 install docker-compose
#sudo docker-compose -f docker-compose-profess.yml pull ofw
sudo usermod -a -G docker $USER
sudo reboot

I had similar problem, and I solved it as folows:

I working on MS SQL 2008, but in the NH configuration I had bad dialect: NHibernate.Dialect.MsSql2005Dialect if I correct it to: NHibernate.Dialect.MsSql2008Dialect then everything's working fine without a exception "No persister for: ..." David.

The SelectMany() method is used to flatten a sequence in which each of the elements of the sequence is a separate.

I have class user same like this

class User
    {
        public string UserName { get; set; }
        public List<string> Roles { get; set; }
    }

main:

var users = new List<User>
            {
                new User { UserName = "Reza" , Roles = new List<string>{"Superadmin" } },
                new User { UserName = "Amin" , Roles = new List<string>{"Guest","Reseption" } },
                new User { UserName = "Nima" , Roles = new List<string>{"Nurse","Guest" } },
            };

var query = users.SelectMany(user => user.Roles, (user, role) => new { user.UserName, role });

foreach (var obj in query)
{
    Console.WriteLine(obj);
}
//output

//{ UserName = Reza, role = Superadmin }
//{ UserName = Amin, role = Guest }
//{ UserName = Amin, role = Reseption }
//{ UserName = Nima, role = Nurse }
//{ UserName = Nima, role = Guest }

You can use operations on any item of sequence

int[][] numbers = {
                new[] {1, 2, 3},
                new[] {4},
                new[] {5, 6 , 6 , 2 , 7, 8},
                new[] {12, 14}
            };

IEnumerable<int> result = numbers
                .SelectMany(array => array.Distinct())
                .OrderBy(x => x);

//output

//{ 1, 2 , 2 , 3, 4, 5, 6, 7, 8, 12, 14 }

 List<List<int>> numbers = new List<List<int>> {
                new List<int> {1, 2, 3},
                new List<int> {12},
                new List<int> {5, 6, 5, 7},
                new List<int> {10, 10, 10, 12}
            };

 IEnumerable<int> result = numbers
                .SelectMany(list => list)
                .Distinct()
                .OrderBy(x=>x);

//output

// { 1, 2, 3, 5, 6, 7, 10, 12 }

This question has lots of good answers even for .Net Core. I was using both Frameworks the provided code samples work fine. So I won't repeat it. In my case the important thing was how to use File upload actions with Swagger like this:

Here is my recap:

ASP .Net WebAPI 2

• To upload file use: MultipartFormDataStreamProvider see answers here
• How to use it with Swagger

.NET Core

• To upload file use: IFormFile see answers here or MS documentation
• How to use it with Swagger

netstat -ano|find ":port_no" will give you the list.
a: Displays all connections and listening ports.
n: Displays addresses and port numbers in numerical form.
o: Displays the owning process ID associated with each connection .

example : netstat -ano | find ":1900" This gives you the result like this.

UDP    107.109.121.196:1900   *:*                                    1324  
UDP    127.0.0.1:1900         *:*                                    1324  
UDP    [::1]:1900             *:*                                    1324  
UDP    [fe80::8db8:d9cc:12a8:2262%13]:1900  *:*                      1324

This can be an efficient way of performing different tests on a single statement

select
case colour_txt 
  when 'red' then 5 
  when 'green' then 4 
  when 'orange' then 3
else 0 
end as Pass_Flag

this only works on equality comparisons!

Here is described Java method:

java.lang.String    getText() 

But unfortunately it's not available in Python. So you can translate the method names to Python from Java and try another logic using present methods without getting the whole page source...

E.g.

 my_id = elem[0].get_attribute('my-id')

Building off of Viktar's answer, here's an implementation you can call once on a given hidden input element to ensure that subsequent change events get fired whenever the value of the input element changes:

/**
 * Modifies the provided hidden input so value changes to trigger events.
 *
 * After this method is called, any changes to the 'value' property of the
 * specified input will trigger a 'change' event, just like would happen
 * if the input was a text field.
 *
 * As explained in the following SO post, hidden inputs don't normally
 * trigger on-change events because the 'blur' event is responsible for
 * triggering a change event, and hidden inputs aren't focusable by virtue
 * of being hidden elements:
 * https://stackoverflow.com/a/17695525/4342230
 *
 * @param {HTMLInputElement} inputElement
 *   The DOM element for the hidden input element.
 */
function setupHiddenInputChangeListener(inputElement) {
  const propertyName = 'value';

  const {get: originalGetter, set: originalSetter} =
    findPropertyDescriptor(inputElement, propertyName);

  // We wrap this in a function factory to bind the getter and setter values
  // so later callbacks refer to the correct object, in case we use this
  // method on more than one hidden input element.
  const newPropertyDescriptor = ((_originalGetter, _originalSetter) => {
    return {
      set: function(value) {
        const currentValue = originalGetter.call(inputElement);

        // Delegate the call to the original property setter
        _originalSetter.call(inputElement, value);

        // Only fire change if the value actually changed.
        if (currentValue !== value) {
          inputElement.dispatchEvent(new Event('change'));
        }
      },

      get: function() {
        // Delegate the call to the original property getter

In some languages, you can use an alternative library, For example, tampax is an implementation of YAML handling variables:

const tampax = require('tampax');

const yamlString = `
dude:
  name: Arthur
weapon:
  favorite: Excalibur
  useless: knife
sentence: "{{dude.name}} use {{weapon.favorite}}. The goal is {{goal}}."`;

const r = tampax.yamlParseString(yamlString, { goal: 'to kill Mordred' });
console.log(r.sentence);

// output : "Arthur use Excalibur. The goal is to kill Mordred."

If you want to be really fancy, download TCPView from Sysinternals:

TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, and XP, TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows.

Here's mine. It runs in <2ms in Google Apps Script on a sizable object. It uses dashes instead of dots for separators, and it doesn't handle arrays specially like in the asker's question, but this is what I wanted for my use.

function flatten (obj) {
  var newObj = {};
  for (var key in obj) {
    if (typeof obj[key] === 'object' && obj[key] !== null) {
      var temp = flatten(obj[key])
      for (var key2 in temp) {
        newObj[key+"-"+key2] = temp[key2];
      }
    } else {
      newObj[key] = obj[key];
    }
  }
  return newObj;
}

Example:

var test = {
  a: 1,
  b: 2,
  c: {
    c1: 3.1,
    c2: 3.2
  },
  d: 4,
  e: {
    e1: 5.1,
    e2: 5.2,

You could also just call to_a after each_byte or even better String#bytes

=> 'hello world'.each_byte.to_a
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

=> 'hello world'.bytes
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

Just before your "Content of the letter" line, add \thispagestyle{fancy} and it should show the headers you defined. (It worked for me.)

Here's the full document that I used to test:

\documentclass[12pt]{letter}

\usepackage{fontspec}% font selecting commands 
\usepackage{xunicode}% unicode character macros 
\usepackage{xltxtra} % some fixes/extras 

% page counting, header/footer
\usepackage{fancyhdr}
\usepackage{lastpage}

\pagestyle{fancy}
\lhead{\footnotesize \parbox{11cm}{Draft 1} }
\lfoot{\footnotesize \parbox{11cm}{\textit{2}}}
\cfoot{}
\rhead{\footnotesize 3}
\rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}}
\renewcommand{\headheight}{24pt}
\renewcommand{\footrulewidth}{0.4pt}

\usepackage{lipsum}% provides filler text

\begin{document}
\name{ Joe Laroo }
\signature{ Joe Laroo }
\begin{letter}{ To-Address }
\renewcommand{\today}{ February 16, 2009 }
\opening{ Opening }

\thispagestyle{fancy}% sets the current page style to 'fancy' -- must occur *after* \opening
\lipsum[1-10]% just dumps ten paragraphs of filler text

\closing{ Yours truly, }
\end{letter}
\end{document}

The \opening command sets the page style to firstpage or empty, so you have to use \thispagestyle after that command.

My understanding of the events is;

Delegate:

A variable to hold reference to method / methods to be executed. This makes it possible to pass around methods like a variable.

Steps for creating and calling the event:

1. The event is an instance of a delegate

2. Since an event is an instance of a delegate, then we have to first define the delegate.

3. Assign the method / methods to be executed when the event is fired (Calling the delegate)

4. Fire the event (Call the delegate)

Example:

using System;

namespace test{
    class MyTestApp{
        //The Event Handler declaration
        public delegate void EventHandler();

        //The Event declaration
        public event EventHandler MyHandler;

        //The method to call
        public void Hello(){
            Console.WriteLine("Hello World of events!");
        }

        public static void Main(){
            MyTestApp TestApp = new MyTestApp();

            //Assign the method to be called when the event is fired
            TestApp.MyHandler = new EventHandler(TestApp.Hello);

            //Firing the event
            if (TestApp.MyHandler != null){
                TestApp.MyHandler();
            }
        }

    }   

}

There are two ways this could be achieved.

DateTimeFormat

DateTimeFormat.forPattern("dd/MM/yyyy HH:mm:ss").parseDateTime("04/02/2011 20:27:05");

SimpleDateFormat

        String dateValue = "04/02/2011 20:27:05";
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss"); //  04/02/2011 20:27:05

        Date date = sdf.parse(dateValue); // returns date object
        System.out.println(date); // outputs: Fri Feb 04 20:27:05 IST 2011

Whenever you are working with csv imports, try to use df.dropna() to avoid all such warnings or errors.

Javascript may be hooking up to the click-event of the anchor, rather than injecting any href.

For example, jQuery:

$('a.view').click(function() { Alert('anchor without a href was clicked');});

Of course, the javascript can do anything it wants with the click event--such as navigate to some other page (in which case the href is never set, but the anchor still behaves as though it were)

echo "word1 word2" | cut -f 1 -d " "

cut cuts the 1st field (-f 1) from a list of fields delimited by the string " " (-d " ")

Expanding on AnaPana's answer, how to remove an extension using pathlib (Python >= 3.4):

>>> from pathlib import Path

>>> filename = Path('/some/path/somefile.txt')

>>> filename_wo_ext = filename.with_suffix('')

>>> filename_replace_ext = filename.with_suffix('.jpg')

>>> print(filename)
/some/path/somefile.ext    

>>> print(filename_wo_ext)
/some/path/somefile

>>> print(filename_replace_ext)
/some/path/somefile.jpg

Use the not function instead:

var lastOpenSite = $(this).siblings().not('.closedTab');

hasClass only tests whether an element has a class, not will remove elements from the selected set matching the provided selector.

You can run the below script in the Manage Jenkins ? Scripts Console for deleting the workspaces of all the jobs at one shot. We did this to clean up space on the file system.

import hudson.model.*
// For each project
for(item in Hudson.instance.items) {
  // check that job is not building
  if(!item.isBuilding()) {
    println("Wiping out workspace of job "+item.name)
    item.doDoWipeOutWorkspace()
  }
  else {
    println("Skipping job "+item.name+", currently building")
  }
}

Java code:

Pattern pattern1 = Pattern.compile("(\\_\\(.*?\\))");
System.out.println(fileName.replace(matcher1.group(1), ""));

The length of the segment is not important, thus using a square root is not required and should be avoided since we could lose some precision.

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

class Segment:
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def is_between(self, c):
        # Check if slope of a to c is the same as a to b ;
        # that is, when moving from a.x to c.x, c.y must be proportionally
        # increased than it takes to get from a.x to b.x .

        # Then, c.x must be between a.x and b.x, and c.y must be between a.y and b.y.
        # => c is after a and before b, or the opposite
        # that is, the absolute value of cmp(a, b) + cmp(b, c) is either 0 ( 1 + -1 )
        #    or 1 ( c == a or c == b)

        a, b = self.a, self.b             

        return ((b.x - a.x) * (c.y - a.y) == (c.x - a.x) * (b.y - a.y) and 
                abs(cmp(a.x, c.x) + cmp(b.x, c.x)) <= 1 and
                abs(cmp(a.y, c.y) + cmp(b.y, c.y)) <= 1)

Some random example of usage :

a = Point(0,0)
b = Point(50,100)
c = Point(25,50)
d = Point(0,8)

print Segment(a,b).is_between(c)
print Segment(a,b).is_between(d)

You need a Flask view that will receive POST data and an HTML form that will send it.

from flask import request

@app.route('/addRegion', methods=['POST'])
def addRegion():
    ...
    return (request.form['projectFilePath'])

<form action="{{ url_for('addRegion') }}" method="post">
    Project file path: <input type="text" name="projectFilePath"><br>
    <input type="submit" value="Submit">
</form>

Try this code it's really working.

int number = 0;
try {
    number = Integer.parseInt(YourEditTextName.getText().toString());
} catch(NumberFormatException e) {
   System.out.println("parse value is not valid : " + e);
} 

>>> a = 147.234
>>> a % 1
0.23400000000000887
>>> a // 1
147.0
>>>

If you want the integer part as an integer and not a float, use int(a//1) instead. To obtain the tuple in a single passage: (int(a//1), a%1)

EDIT: Remember that the decimal part of a float number is approximate, so if you want to represent it as a human would do, you need to use the decimal library

Check to see if you have a Debuggable attribute in your AssemblyInfo file. If there is, remove it and rebuild your solution to see if the local variables become available.

My debuggable attribute was set to: DebuggableAttribute.DebuggingModes.IgnoreSymbolStoreSequencePoints which according to this MSDN article tells the JIT compiler to use optimizations. I removed this line from my AssemblyInfo.cs file and the local variables were available.

I recently did a very similar thing to make a type safe OnPropertyChanged method.

Here's a method that'll return the PropertyInfo object for the expression. It throws an exception if the expression is not a property.

public PropertyInfo GetPropertyInfo<TSource, TProperty>(
    TSource source,
    Expression<Func<TSource, TProperty>> propertyLambda)
{
    Type type = typeof(TSource);

    MemberExpression member = propertyLambda.Body as MemberExpression;
    if (member == null)
        throw new ArgumentException(string.Format(
            "Expression '{0}' refers to a method, not a property.",
            propertyLambda.ToString()));

    PropertyInfo propInfo = member.Member as PropertyInfo;
    if (propInfo == null)
        throw new ArgumentException(string.Format(
            "Expression '{0}' refers to a field, not a property.",
            propertyLambda.ToString()));

    if (type != propInfo.ReflectedType &&
        !type.IsSubclassOf(propInfo.ReflectedType))
        throw new ArgumentException(string.Format(
            "Expression '{0}' refers to a property that is not from type {1}.",
            propertyLambda.ToString(),
            type));

    return propInfo;
}

The source parameter is used so the compiler can do type inference on the method call. You can do the following

var propertyInfo = GetPropertyInfo(someUserObject, u => u.UserID);

AND, if you just want to get a count of all the rows in a table

$table_row_count = $this->db->count_all('table_name');

It may be useful for someone, so I'll post it here. I was missing this dependency on my pom.xml

By adding a few more headers I was able to get the data:

import urllib2,cookielib

site= "http://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/getHistoricalData.jsp?symbol=JPASSOCIAT&fromDate=1-JAN-2012&toDate=1-AUG-2012&datePeriod=unselected&hiddDwnld=true"
hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
       'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
       'Accept-Encoding': 'none',
       'Accept-Language': 'en-US,en;q=0.8',
       'Connection': 'keep-alive'}

req = urllib2.Request(site, headers=hdr)

try:
    page = urllib2.urlopen(req)
except urllib2.HTTPError, e:
    print e.fp.read()

content = page.read()
print content

Actually, it works with just this one additional header:

'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',

Setting the photo as a background image will give us more control over size and placement, leaving the img tag to serve a different purpose...

Below, if we want the div to be the same aspect ratio as the photo, then placeholder.png is a small transparent image with the same aspect ratio as photo.jpg. If the photo is a square, it's a 1px x 1px placeholder, if the photo is a video thumbnail, it's a 16x9 placeholder, etc.

Specific to the question, use a 1x1 placeholder to maintain the div's square ratio, with a background image using background-size to maintain the photo's aspect ratio.

I used background-position: center center; so the photo will be centered in the div. (Aligning the photo in the vertical center or bottom would get ugly with the photo in the img tag.)

div {
    background: url(photo.jpg) center center no-repeat;
    background-size: contain;
    width: 48px; // or a % in responsive layout
}
img {
    width: 100%;
}

<div><img src="placeholder.png"/></div>

To avoid an extra http request, convert the placeholder image to a data: URL.

<img src="data:image/png;base64,..."/>

I would try setting it to max-width:50px;

I had trouble with this using matplotlib version: 2.0.2. Running the example from above I got a centered stacked set of bubbles.

I "fixed" the problem by adding another line:

plt.plot([],[])

The entire code snippet becomes:

import datetime
import random
import matplotlib.pyplot as plt
import matplotlib.dates as mdates


# make up some data
x = [datetime.datetime.now() + datetime.timedelta(minutes=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.plot([],[])
plt.scatter(x,y)

# beautify the x-labels
plt.gcf().autofmt_xdate()
myFmt = mdates.DateFormatter('%H:%M')
plt.gca().xaxis.set_major_formatter(myFmt)

plt.show()
plt.close()

This produces an image with the bubbles distributed as desired.

From git reset

"pull" or "merge" always leaves the original tip of the current branch in ORIG_HEAD.

git reset --hard ORIG_HEAD

Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.

git reset --merge ORIG_HEAD

After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "git reset --hard ORIG_HEAD" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge" keeps your local changes.

Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).

In addition, merge always sets '.git/ORIG_HEAD' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD'.

Note: from here

HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.

So HEAD is NOT a synonym for "current branch" everywhere already.

HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).

But it almost always means the "current commit".
It is the commit "git commit" builds on top of, and "git diff --cached" and "git status" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).

Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".

HEAD@{5.minutes.ago} could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".

git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.

Instead of typing four capital letters "HEAD", you can say "@" now,
e.g. "git log @".

See commit cdfd948

Typing 'HEAD' is tedious, especially when we can use '@' instead.

The reason for choosing '@' is that it follows naturally from the ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD'.

So now we can use 'git show @~1', and all that goody goodness.

Until now '@' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.

If you want to switch the jdk on a regular basis (or update to a new one once it is released), it's very conveniant to use sdkman.

You can additional tools like maven with sdkman, too.

Well, I'd say use the DIV instead of table as it would be much easier (but there's nothing wrong with using tables).

My approach would be to use jQuery.ajax and request more data from server and that way, the selected DIV (or TD if you use table) will automatically expand based on requested content.

That way, it saves bandwidth and makes it go faster as you don't load all content at once. It loads only when it's selected.

One more reason, maybe your url include some hiden characters, such as '\n'.

If you define your url like below, this exception will raise:

url = '''
http://google.com
'''

because there are '\n' hide in the string. The url in fact become:

\nhttp://google.com\n

I don't know how the table is created but try this...

SELECT users1.user_id, users2.user_parent_id
FROM users AS users1
INNER JOIN users AS users2
ON users1.id = users2.id
WHERE users1.user_id = users2.user_parent_id

The above did not work for me but this did

<%= link_to "text_to_show_in_url", action_controller_path(:gender => "male", :param2=> "something_else") %>

ES6: In HTML, include the main JavaScript file using attribute type="module" (browser support):

<script type="module" src="script.js"></script>

And in the script.js file, include another file like this:

import { hello } from './module.js';
...
// alert(hello());

Inside the included file (module.js), you must export the function/class that you will import:

export function hello() {
    return "Hello World";
}

A working example is here. More information is here.

A Relation object passes unknown method calls through to an Eloquent query Builder, which is set up to only select the related objects. That Builder in turn passes unknown method calls through to its underlying query Builder.

This means you can use the exists() or count() methods directly from a relation object:

$model->relation()->exists(); // bool: true if there is at least one row
$model->relation()->count(); // int: number of related rows

Note the parentheses after relation: ->relation() is a function call (getting the relation object), as opposed to ->relation which a magic property getter set up for you by Laravel (getting the related object/objects).

Using the count method on the relation object (that is, using the parentheses) will be much faster than doing $model->relation->count() or count($model->relation) (unless the relation has already been eager-loaded) since it runs a count query rather than pulling all of the data for any related objects from the database, just to count them. Likewise, using exists doesn't need to pull model data either.

Both exists() and count() work on all relation types I've tried, so at least belongsTo, hasOne, hasMany, and belongsToMany.

Another solution that does not involve converting to/from strings:

from math import log10

def decompose(n):
    if n == 0:
        return [0]
    b = int(log10(n)) + 1
    return [(n // (10 ** i)) % 10 for i in reversed(range(b))]

To remove everything before the first /

input = input.Substring(input.IndexOf("/"));

To remove everything after the first /

input = input.Substring(0, input.IndexOf("/") + 1);

To remove everything before the last /

input = input.Substring(input.LastIndexOf("/"));

To remove everything after the last /

input = input.Substring(0, input.LastIndexOf("/") + 1);

An even more simpler solution for removing characters after a specified char is to use the String.Remove() method as follows:

To remove everything after the first /

input = input.Remove(input.IndexOf("/") + 1);

To remove everything after the last /

input = input.Remove(input.LastIndexOf("/") + 1);

Since the img is an inline element, Just use text-center on it's container. Using mx-auto will center the container (column) too.

<div class="row">
    <div class="col-4 mx-auto text-center">
        <img src="..">
    </div>
</div>

By default, images are display:inline. If you only want the center the image (and not the other column content), make the image display:block using the d-block class, and then mx-auto will work.

<div class="row">
  <div class="col-4">
    <img class="mx-auto d-block" src="..">
  </div>
</div>

You may use Dynamic Programmining. Algo complexity is O(Sum * N) and use O(Sum) memory.

Here's my implementation in C#:

private static int GetmNumberOfSubsets(int[] numbers, int sum)
{
    int[] dp = new int[sum + 1];
    dp[0] = 1;
    int currentSum =0;
    for (int i = 0; i < numbers.Length; i++)
    {
        currentSum += numbers[i];
        for (int j = Math.Min(sum, currentSum); j >= numbers[i]; j--)
            dp[j] += dp[j - numbers[i]];
    }

    return dp[sum];
}

Notes: As number of subsets may have value 2^N it easy may overflows int type.

Algo works only for positive numbers.

JSONB is a "better" version of JSON.

Let's look at an example:

SELECT '{"c":0,   "a":2,"a":1}'::json, '{"c":0,   "a":2,"a":1}'::jsonb;

          json          |        jsonb 
------------------------+--------------------- 
 {"c":0,   "a":2,"a":1} | {"a": 1, "c": 0} 
(1 row)

1. JSON stores white space, they is why we can see spaces when key "a" is stored, while JSONB does not.
2. JSON stores all the values of key. This is the reason you can see multiple values (2 and 1) against the key "a" , while JSONB only "stores" the last value.
3. JSON maintains the order in which elements are inserted, while JSONB maintains the "sorted" order.
4. JSONB objects are stored as decompressed binary as opposed to "raw data" in JSON , where no reparsing of data is required during retrieval.
5. JSONB also supports indexing, which can be a significant advantage.

In general, one should prefer JSONB , unless there are specialized needs, such as legacy assumptions about ordering of object keys.

Get the difference between the two dates and then get the days from:

int total_days = (EndDate - StartDate).TotalDays

To open in a new windows with dimensions and everything, you will need to call a JavaScript function, as target="_blank" won't let you adjust sizes. An example would be:

<a href="http://www.facebook.com/sharer" onclick="window.open(this.href, 'mywin',
'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); return false;" >Share this</a>

Hope this helps you.

This should work for you:

$(document).ready(function () {
    $('.applicationButton').click(function (e) {
        var btn = $(this),
            isPageValid = Page_ClientValidate(); // cache state of page validation
        if (!isPageValid) {
            // page isn't valid, block form submission
            e.preventDefault();
        }
        // disable the button only if the page is valid.
        // when the postback returns, the button will be re-enabled by default
        btn.prop('disabled', isPageValid);
        return isPageValid;
    });
});

Please note that you should also take steps server-side to prevent double-posts as not every visitor to your site will be polite enough to visit it with a browser (let alone a JavaScript-enabled browser).

I find that using Apache Commons IO makes my life much easier.

String source = "This is the source of my input stream";
InputStream in = org.apache.commons.io.IOUtils.toInputStream(source, "UTF-8");

You may find that the library also offer many other shortcuts to commonly done tasks that you may be able to use in your project.

Either use loop counting down over indices:

for (NSInteger i = array.count - 1; i >= 0; --i) {

or make a copy with the objects you want to keep.

In particular, do not use a for (id object in array) loop or NSEnumerator.

Follow these simple steps :

1: In the Rmarkdown script run Knit(Ctrl+Shift+K) 2: Then after the html markdown is opened click Open in Browser(top left side) and the html is opened in your web browser 3: Then use Ctrl+P and save as PDF .

I would use this:

$parts = explode('-', '2068-06-15');
echo $parts[0];

It appears the date is coming from a source where it is always the same, much quicker this way using explode.

The most rank answer in this post work, however its is CSV file. It is not actual Excel file. Therefore, you will get a warning when you are opening a file.

The best solution I found on the web is using CloseXML https://github.com/closedxml/closedxml You need to Open XML as well.

 dt = city.GetAllCity();//your datatable
 using (XLWorkbook wb = new XLWorkbook())
    {
        wb.Worksheets.Add(dt);

        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "";
        Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
        Response.AddHeader("content-disposition", "attachment;filename=GridView.xlsx");
        using (MemoryStream MyMemoryStream = new MemoryStream())
        {
            wb.SaveAs(MyMemoryStream);
            MyMemoryStream.WriteTo(Response.OutputStream);
            Response.Flush();
            Response.End();
        }
    }

I have a feeling that your ClientID is not of a string type (zero-terminated char* or std::string) but some integral type (e.g. int) so you need to convert number to the string first:

std::stringstream ss;
ss << ClientID;
query.append(ss.str());

But you can use operator+ as well (instead of append):

query += ss.str();

Here is a complete example that has been tested with Python 2.7.5 on CentOS 7.

#!/usr/bin/python

import sys, socket

def main(args):
    ip = args[1]
    port = int(args[2])
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    file = 'sample.csv'

    fp = open(file, 'r')
    for line in fp:
        sock.sendto(line.encode('utf-8'), (ip, port))
    fp.close()

main(sys.argv)

The program reads a file, sample.csv from the current directory and sends each line in a separate UDP packet. If the program it were saved in a file named send-udp then one could run it by doing something like:

$ python send-udp 192.168.1.2 30088

Maybe you're looking for something like this:

$(document).click(function(e)
   {
       if($(e.srcElement).attr('id')=='id')
       {
           alert('click on #id');
       }
       else
       {
            alert('click on something else'); 
       }
   });

jsfiddle

You may retrieve a pointer to the clicked element using event.srcElement .

So all you have to do is to check the id-attribute of the clicked element.

Design patterns aren't trivially reusable solutions.

Design patterns are reusable, by definition. They're patterns you detect in other good solutions.

A pattern is not trivially reusable. You can implement your down design following the pattern however.

Relational design patters include things like:

1. One-to-Many relationships (master-detail, parent-child) relationships using a foreign key.

2. Many-to-Many relationships with a bridge table.

3. Optional one-to-one relationships managed with NULLs in the FK column.

4. Star-Schema: Dimension and Fact, OLAP design.

5. Fully normalized OLTP design.

6. Multiple indexed search columns in a dimension.

7. "Lookup table" that contains PK, description and code value(s) used by one or more applications. Why have code? I don't know, but when they have to be used, this is a way to manage the codes.

8. Uni-table. [Some call this an anti-pattern; it's a pattern, sometimes it's bad, sometimes it's good.] This is a table with lots of pre-joined stuff that violates second and third normal form.

9. Array table. This is a table that violates first normal form by having an array or sequence of values in the columns.

10. Mixed-use database. This is a database normalized for transaction processing but with lots of extra indexes for reporting and analysis. It's an anti-pattern -- don't do this. People do it anyway, so it's still a pattern.

Most folks who design databases can easily rattle off a half-dozen "It's another one of those"; these are design patterns that they use on a regular basis.

And this doesn't include administrative and operational patterns of use and management.

Inspired by samneric's answer using DataRowComparer.Default but needing something that would only compare a subset of columns within a DataTable, I made a DataTableComparer object where you can specify which columns to use in the comparison. Especially great if they have different columns/schemas.

DataRowComparer.Default works because it implements IEqualityComparer. Then I created an object where you can define which columns of the DataRow will be compared.

public class DataTableComparer : IEqualityComparer<DataRow>
{
    private IEnumerable<String> g_TestColumns;
    public void SetCompareColumns(IEnumerable<String> p_Columns)
    {
        g_TestColumns = p_Columns; 
    }

    public bool Equals(DataRow x, DataRow y)
    {

        foreach (String sCol in g_TestColumns)
            if (!x[sCol].Equals(y[sCol])) return false;

        return true;
    }

    public int GetHashCode(DataRow obj)
    {
        StringBuilder hashBuff = new StringBuilder();

        foreach (String sCol in g_TestColumns)
            hashBuff.AppendLine(obj[sCol].ToString());               

        return hashBuff.ToString().GetHashCode();

    }
}

You can use this by:

DataTableComparer comp = new DataTableComparer();
comp.SetCompareColumns(new String[] { "Name", "DoB" });

DataTable celebrities = SomeDataTableSource();
DataTable politicians = SomeDataTableSource2();

List<DataRow> celebrityPoliticians = celebrities.AsEnumerable().Intersect(politicians.AsEnumerable(), comp).ToList();

If you wrap each template in a script tag, eg:

<script id="about.html" type="text/ng-template">
<div>
    <h3>About</h3>
    This is the About page
    Its cool!
</div>
</script>

Concatenate all templates into 1 big file. If using Visual Studio 2013, download Web essentials - it adds a right click menu to create an HTML Bundle.

Add the code that this guy wrote to change the angular $templatecache service - its only a small piece of code and it works: Vojta Jina's Gist

Its the $http.get that should be changed to use your bundle file:

allTplPromise = $http.get('templates/templateBundle.min.html').then(

Your routes templateUrl should look like this:

        $routeProvider.when(
            "/about", {
                controller: "",
                templateUrl: "about.html"
            }
        );

To set your App or any individual activity display in Full Screen mode, insert the code

<application 
    android:icon="@drawable/icon" 
    android:label="@string/app_name" 
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

in AndroidManifest.xml, under application or activity tab.

Tried all but change in .svn directly. Nothing helped so here's my solution.

In Eclipse > Window > Show View > History I've seen that file is not at the newest Revision, although I made multiple svn "Override & Update" / "Revert" / delete file and checkout.

So I went Package Explorer > Right click on file > Replace with > Latest from Repository.

Another look in the History View showed that file was now on latest Revision.

For variables describing distances, you would use \newlength (and manipulate the values with \setlength, \addlength, \settoheight, \settolength and \settodepth).

Similarly you have access to \newcounter for things like section and figure numbers which should increment throughout the document. I've used this one in the past to provide code samples that were numbered separatly of other figures...

Also of note is \makebox which allows you to store a bit of laid-out document for later re-use (and for use with \settolength...).

You can first concatenate the strings in the list with the separator ';' using the function join and then use the split function in order create the list:

l = ['Facebook;Google+;MySpace', 'Apple;Android']

l1 = ";".join(l)).split(";")  

print l1

outputs

['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']

dmidecode -t 17 | grep  Size:

Adding all above values displayed after "Size: " will give exact total physical size of all RAM sticks in server.

There's one more difference. class can be used to define type properties of computed type only. If you need a stored type property use static instead.

"You define type properties with the static keyword. For computed type properties for class types, you can use the class keyword instead to allow subclasses to override the superclass’s implementation."

Sometimes learning by example helps the most. Run this console application in three different console windows. You'll see that the application you ran first acquires the mutex first, while the other two are waiting their turn. Then press enter in the first application, you'll see that application 2 now continues running by acquiring the mutex, however application 3 is waiting its turn. After you press enter in application 2 you'll see that application 3 continues. This illustrates the concept of a mutex protecting a section of code to be executed only by one thread (in this case a process) like writing to a file as an example.

using System;
using System.Threading;

namespace MutexExample
{
    class Program
    {
        static Mutex m = new Mutex(false, "myMutex");//create a new NAMED mutex, DO NOT OWN IT
        static void Main(string[] args)
        {
            Console.WriteLine("Waiting to acquire Mutex");
            m.WaitOne(); //ask to own the mutex, you'll be queued until it is released
            Console.WriteLine("Mutex acquired.\nPress enter to release Mutex");
            Console.ReadLine();
            m.ReleaseMutex();//release the mutex so other processes can use it
        }
    }
}

Say you have a child_method() in the child component:

export default {
    methods: {
        child_method () {
            console.log('I got clicked')
        }
    }
}

Now you want to execute the child_method from parent component:

<template>
    <div>
        <button @click="exec">Execute child component</button>
        <child-cmp ref="child"></child_cmp> <!-- note the ref="child" here -->
    </div>
</template>

export default {
    methods: {
        exec () { //accessing the child component instance through $refs
            this.$refs.child.child_method() //execute the method belongs to the child component
        }
    }
}

If you want to execute a parent component method from child component:

this.$parent.name_of_method()

NOTE: It is not recommended to access the child and parent component like this.

Instead as best practice use Props & Events for parent-child communication.

If you want communication between components surely use vuex or event bus

Please read this very helpful article

Change this:

`create_date` TIMESTAMP NOT NULL DEFAULT  '0000-00-00 00:00:00',
`update_date` TIMESTAMP NOT NULL DEFAULT  CURRENT_TIMESTAMP  ,

To the following:

`create_date` TIMESTAMP NOT NULL DEFAULT  CURRENT_TIMESTAMP ,
`update_date` TIMESTAMP NOT NULL DEFAULT  CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP ,

valign="top" should do the work.

<tr>_x000D_
  <td valign="top">Description</td>_x000D_
</tr>

Here is an alternative way if the data frame just contains numbers.

apply(as.matrix.noquote(SFI),2,as.numeric)

but the most reliable way of converting a data frame to a matrix is using data.matrix() function.

You don't need to add the concat package, you can do this via cssmin like this:

cssmin : {
      options: {
            keepSpecialComments: 0
      },
      minify : {
            expand : true,
            cwd : '/library/css',
            src : ['*.css', '!*.min.css'],
            dest : '/library/css',
            ext : '.min.css'
      },
      combine : {
        files: {
            '/library/css/app.combined.min.css': ['/library/css/main.min.css', '/library/css/font-awesome.min.css']
        }
      }
    }

And for js, use uglify like this:

uglify: {
      my_target: {
        files: {
            '/library/js/app.combined.min.js' : ['/app.js', '/controllers/*.js']
        }
      }
    }

change your

return @str1+'present in the string' ;

to

set @r = @str1+'present in the string'
