This Did the trick for me, for IIS 8 Windows server 2012 R2

Go to "Turn on Features"

Then go to all default setting , Next, Next, Next etc..

Then, select as shown below,

Then reset IIS (optional) but do it safer side.

This is an additional solution as its a generic problem everyone have different of problem and thus different solution. Cheers!

As Niklas mentioned you can use the html2canvas library to take a screenshot using JS in the browser. I will extend his answer in this point by providing an example of taking a screenshot using this library ("Proof of Concept"):

function report() {
  let region = document.querySelector("body"); // whole screen
  html2canvas(region, {
    onrendered: function(canvas) {
      let pngUrl = canvas.toDataURL(); // png in dataURL format
      let img = document.querySelector(".screen");
      img.src = pngUrl; 

      // here you can allow user to set bug-region
      // and send it with 'pngUrl' to server
    },
  });
}

.container {
  margin-top: 10px;
  border: solid 1px black;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
<div>Screenshot tester</div>
<button onclick="report()">Take screenshot</button>

<div class="container">
  <img width="75%" class="screen">
</div>

In report() function in onrendered after getting image as data URI you can show it to the user and allow him to draw "bug region" by mouse and then send a screenshot and region coordinates to the server.

In this example async/await version was made: with nice makeScreenshot() function.

UPDATE

Simple example which allows you to take screenshot, select region, describe bug and send POST request (here jsfiddle) (the main function is report()).

async function report() {
    let screenshot = await makeScreenshot(); // png dataUrl
    let img = q(".screen");
    img.src = screenshot; 
    
    let c = q(".bug-container");
    c.classList.remove('hide')
        
    let box = await getBox();    
    c.classList.add('hide');

    send(screenshot,box); // sed post request  with bug image, region and description
    alert('To see POST requset with image go to: chrome console > network tab');
}

// ----- Helper functions

let q = s => document.querySelector(s); // query selector helper
window.report = report; // bind report be visible in fiddle html

async function  makeScreenshot(selector="body") 
{
  return new Promise((resolve, reject) => {  
    let node = document.querySelector(selector);
    
    html2canvas(node, { onrendered: (canvas) => {
        let pngUrl = canvas.toDataURL();      
        resolve(pngUrl);
    }});  
  });
}

async function getBox(box) {
  return new Promise((resolve, reject) => {
     let b = q(".bug");
     let r = q(".region");
     let scr = q(".screen");
     let send = q(".send");
     let start=0;
     let sx,sy,ex,ey=-1;
     r.style.width=0;
     r.style.height=0;
     
     let drawBox= () => {
         r.style.left   = (ex > 0 ? sx : sx+ex ) +'px'; 
         r.style.top    = (ey > 0 ? sy : sy+ey) +'px';
         r.style.width  = Math.abs(ex) +'px';
         r.style.height = Math.abs(ey) +'px'; 
     }
     
     
     
     //console.log({b,r, scr});
     b.addEventListener("click", e=>{

           drawBox(); 
       }
     });
     
     send.addEventListener("click", e=>{
       start=0;
       let a=100/75 //zoom out img 75%

Try following LOCs

    let query = firestore.collection('events');
    let response = [];
    await query.get().then(querySnapshot => {
          let docs = querySnapshot.docs;
          for (let doc of docs) {
              const selectedEvent = {
                     id: doc.id,
                     item: doc.data().event
                  };
             response.push(selectedEvent);
          }
   return response;

That is the source code for Ants' SCP task. The code in the "execute" method is where the nuts and bolts of it are. This should give you a fair idea of what is required. It uses JSch i believe.

Alternatively you could also directly execute this Ant task from your java code.

It means that there is only one instance of "clock" in Hello, not one per each separate instance of the "Hello" class, or more-so, it means that there will be one commonly shared "clock" reference among all instances of the "Hello" class.

So if you were to do a "new Hello" anywhere in your code: A- in the first scenario (before the change, without using "static"), it would make a new clock every time a "new Hello" is called, but B- in the second scenario (after the change, using "static"), every "new Hello" instance would still share and use the initial and same "clock" reference first created.

Unless you needed "clock" somewhere outside of main, this would work just as well:

package hello;
public class Hello
{
    public static void main(String args[])
    {
      Clock clock=new Clock();
      clock.sayTime();    
    }
}

You can run your code without any issues if you somehow manually ignore the Pool object from the list of objects in the class because it is not pickleable as the error says. You can do this with the __getstate__ function (look here too) as follow. The Pool object will try to find the __getstate__ and __setstate__ functions and execute them if it finds it when you run map, map_async etc:

class calculate(object):
    def __init__(self):
        self.p = Pool()
    def __getstate__(self):
        self_dict = self.__dict__.copy()
        del self_dict['p']
        return self_dict
    def __setstate__(self, state):
        self.__dict__.update(state)

    def f(self, x):
        return x*x
    def run(self):
        return self.p.map(self.f, [1,2,3])

Then do:

cl = calculate()
cl.run()

will give you the output:

[1, 4, 9]

I've tested the above code in Python 3.x and it works.

The title of the question asks about precision. BigDecimal distinguishes between scale and precision. Scale is the number of decimal places. You can think of precision as the number of significant figures, also known as significant digits.

Some examples in Clojure.

(.scale     0.00123M) ; 5
(.precision 0.00123M) ; 3

(In Clojure, The M designates a BigDecimal literal. You can translate the Clojure to Java if you like, but I find it to be more compact than Java!)

You can easily increase the scale:

(.setScale 0.00123M 7) ; 0.0012300M

But you can't decrease the scale in the exact same way:

(.setScale 0.00123M 3) ; ArithmeticException Rounding necessary

You'll need to pass a rounding mode too:

(.setScale 0.00123M 3 BigDecimal/ROUND_HALF_EVEN) ;
; Note: BigDecimal would prefer that you use the MathContext rounding
; constants, but I don't have them at my fingertips right now.

So, it is easy to change the scale. But what about precision? This is not as easy as you might hope!

It is easy to decrease the precision:

(.round 3.14159M (java.math.MathContext. 3)) ; 3.14M

But it is not obvious how to increase the precision:

(.round 3.14159M (java.math.MathContext. 7)) ; 3.14159M (unexpected)

For the skeptical, this is not just a matter of trailing zeros not being displayed:

(.precision (.round 3.14159M (java.math.MathContext. 7))) ; 6 
; (same as above, still unexpected)

FWIW, Clojure is careful with trailing zeros and will show them:

4.0000M ; 4.0000M
(.precision 4.0000M) ; 5

Back on track... You can try using a BigDecimal constructor, but it does not set the precision any higher than the number of digits you specify:

(BigDecimal. "3" (java.math.MathContext. 5)) ; 3M
(BigDecimal. "3.1" (java.math.MathContext. 5)) ; 3.1M

So, there is no quick way to change the precision. I've spent time fighting this while writing up this question and with a project I'm working on. I consider this, at best, A CRAZYTOWN API, and at worst a bug. People. Seriously?

So, best I can tell, if you want to change precision, you'll need to do these steps:

1. Lookup the current precision.
2. Lookup the current scale.
3. Calculate the scale change.
4. Set the new scale

These steps, as Clojure code:

(def x 0.000691M) ; the input number
(def p' 1) ; desired precision
(def s' (+ (.scale x) p' (- (.precision x)))) ; desired new scale
(.setScale x s' BigDecimal/ROUND_HALF_EVEN)
; 0.0007M

I know, this is a lot of steps just to change the precision!

Why doesn't BigDecimal already provide this? Did I overlook something?

One more implementation (in Java). May not be most efficient solution but # of iterations is same as that of Exponential solution.

public static long pow(long base, long exp){        
    if(exp ==0){
        return 1;
    }
    if(exp ==1){
        return base;
    }

    if(exp % 2 == 0){
        long half = pow(base, exp/2);
        return half * half;
    }else{
        long half = pow(base, (exp -1)/2);
        return base * half * half;
    }       
}

If you are only interested in the direct parent, and not other ancestors, you can just use parent(), and give it the selector, as in target.parent('div#hello').

Example: http://jsfiddle.net/6BX9n/

function fun(evt) {
    var target = $(evt.target);    
    if (target.parent('div#hello').length) {
        alert('Your clicked element is having div#hello as parent');
    }
}

Or if you want to check to see if there are any ancestors that match, then use .parents().

Example: http://jsfiddle.net/6BX9n/1/

function fun(evt) {
    var target = $(evt.target);    
    if (target.parents('div#hello').length) {
        alert('Your clicked element is having div#hello as parent');
    }
}

I have recently encountered this problem. Here are the steps to resolve

1. Check the servers section in the settings.xml file.Is username and password correct?

<servers>_x000D_
  <server>_x000D_
    <id>serverId</id>_x000D_
    <username>username</username>_x000D_
    <password>password</password>_x000D_
  </server>_x000D_
</servers>

2. Check the repository section in the pom.xml file.The id of the server tag should be the same as the id of the repository tag.

<repositories>_x000D_
 <repository>_x000D_
   <id>serverId</id>  _x000D_
   <url>http://maven.aliyun.com/nexus/content/groups/public/</url>_x000D_
 </repository>_x000D_
</repositories>

3. If the repository tag is not configured in the pom.xml file, look in the settings.xml file.

<profiles>_x000D_
 <profile>_x000D_
   <repositories>_x000D_
     <repository>_x000D_
      <id>serverId</id>_x000D_
      <name>aliyun</name>_x000D_
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>_x000D_
     </repository>_x000D_
   </repositories>_x000D_
 </profile>_x000D_
</profiles>

Note that you should ensure that the id of the server tag should be the same as the id of the repository tag.

You want this - enter N and then take N number of elements.I am considering your input case is just like this

5
2 3 6 6 5

have this in this way in python 3.x (for python 2.x use raw_input() instead if input())

Python 3

n = int(input())
arr = input()   # takes the whole line of n numbers
l = list(map(int,arr.split(' '))) # split those numbers with space( becomes ['2','3','6','6','5']) and then map every element into int (becomes [2,3,6,6,5])

Python 2

n = int(raw_input())
arr = raw_input()   # takes the whole line of n numbers
l = list(map(int,arr.split(' '))) # split those numbers with space( becomes ['2','3','6','6','5']) and then map every element into int (becomes [2,3,6,6,5])

You can primarily use Zoredache solution, but If you don't want to overwrite the output file you should write tee with -a option as follow :

ls -lR / | tee -a output.file

Instead of setting drawable resource through code in your activity class you can also set in XML layout:

Code is as follows:

<ImageView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/apple" />

You should have a default server for catch-all, you can return 404 or better to not respond at all (will save some bandwidth) by returning 444 which is nginx specific HTTP response that simply close the connection and return nothing

server {
    listen       80  default_server;
    server_name  _; # some invalid name that won't match anything
    return       444;
}

This error caused because of output buffering modules extension(ob_gzhandler) added. While output buffering use at starting ob_start() and ending ob_flush()

<?php   
    ob_start( 'ob_gzhandler' ); 
    echo json_encode($array);
    ob_end_flush();
?>

Use this:

<?php   
    ob_start(); 
    echo json_encode($array);
    ob_flush();
?>

Will result always be the floor of the division?

No. The result varies, but variation happens only for negative values.

What is the defined behavior?

To make it clear floor rounds towards negative infinity,while integer division rounds towards zero (truncates)

For positive values they are the same

int integerDivisionResultPositive= 125/100;//= 1
double flooringResultPositive= floor(125.0/100.0);//=1.0

For negative value this is different

int integerDivisionResultNegative= -125/100;//=-1
double flooringResultNegative= floor(-125.0/100.0);//=-2.0

Set the socket non-blocking, and use select() (which takes a timeout parameter). If a non-blocking socket is trying to connect, then select() will indicate that the socket is writeable when the connect() finishes (either successfully or unsuccessfully). You then use getsockopt() to determine the outcome of the connect():

int main(int argc, char **argv) {
    u_short port;                /* user specified port number */
    char *addr;                  /* will be a pointer to the address */
    struct sockaddr_in address;  /* the libc network address data structure */
    short int sock = -1;         /* file descriptor for the network socket */
    fd_set fdset;
    struct timeval tv;

    if (argc != 3) {
        fprintf(stderr, "Usage %s <port_num> <address>\n", argv[0]);
        return EXIT_FAILURE;
    }

    port = atoi(argv[1]);
    addr = argv[2];

    address.sin_family = AF_INET;
    address.sin_addr.s_addr = inet_addr(addr); /* assign the address */
    address.sin_port = htons(port);            /* translate int2port num */

    sock = socket(AF_INET, SOCK_STREAM, 0);
    fcntl(sock, F_SETFL, O_NONBLOCK);

    connect(sock, (struct sockaddr *)&address, sizeof(address));

    FD_ZERO(&fdset);
    FD_SET(sock, &fdset);
    tv.tv_sec = 10;             /* 10 second timeout */
    tv.tv_usec = 0;

    if (select(sock + 1, NULL, &fdset, NULL, &tv) == 1)
    {
        int so_error;
        socklen_t len = sizeof so_error;

        getsockopt(sock, SOL_SOCKET, SO_ERROR, &so_error, &len);

        if (so_error == 0) {
            printf("%s:%d is open\n", addr, port);
        }
    }

    close(sock);
    return 0;
}

From docs and example it is not clear that classpath manipulation is not allowed.

<configuration>
 <compilerArgs>
  <arg>classpath=${basedir}/lib/bad.jar</arg>
 </compilerArgs>
</configuration>

But see Java docs (also https://www.cis.upenn.edu/~bcpierce/courses/629/jdkdocs/tooldocs/solaris/javac.html)

-classpath path Specifies the path javac uses to look up classes needed to run javac or being referenced by other classes you are compiling. Overrides the default or the CLASSPATH environment variable if it is set.

Maybe it is possible to get current classpath and extend it,
see in maven, how output the classpath being used?

Another solution for typescript user:

import Vue from "vue";
import Component from "vue-class-component";

@Component({
  beforeRouteLeave(to, from, next) {
    // incase if you want to access `this`
    // const self = this as any;
    next();
  }
})

export default class ComponentName extends Vue {}

"currently yes but i think it might cause problems at peak moments" I can confirm, that I had a problem where I got timeouts because of peak requests. After I set the max pool size, the application ran without any problems. IIS 7.5 / ASP.Net

You've probably got one of two problems:

1) You're using JUnit 4.11, which doesn't include hamcrest. Add the hamcrest 1.3 library to your classpath.

2) You've got hamcrest 1.3 on your classpath, but you've got another version of either junit or hamcrest on your classpath.

For background, junit pre 4.11 included a cut down version of hamcrest 1.1. 4.11 removed these classes.

You can inspect elements of a website in your Android device using Chrome browser.

Open your Chrome browser and go to the website you want to inspect.

Go to the address bar and type "view-source:" before the "HTTP" and reload the page.

The whole elements of the page will be shown.

For me nothing worked from suggested above, I use git pull from jenkins shell script and apparently it takes wrong user name. I spent ages before I found a way to fix it without switching to SSH.

In your the user's folder create .gitconfig file (if you don't have it already) and put your credentials in following format: https://user:[email protected], more info. After your .gitconfig file link to those credentials, in my case it was:

[credential] helper = store --file /Users/admin/.git-credentials

Now git will always use those credentials no matter what. I hope it will help someone, like it helped me.

In jQuery just use:

$('#tblOne > tbody  > tr').each(function() {...code...});

Using the children selector (>) you will walk over all the children (and not all descendents), example with three rows:

$('table > tbody  > tr').each(function(index, tr) { 
   console.log(index);
   console.log(tr);
});

Result:

0
<tr>
1 
<tr>
2
<tr>

In VanillaJS you can use document.querySelectorAll() and walk over the rows using forEach()

[].forEach.call(document.querySelectorAll('#tblOne > tbody  > tr'), function(index, tr) {
    /* console.log(index); */
    /* console.log(tr); */
});

All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)

Based on this related answer, you are looking at a list that looks like: A-Z, a-z, 0-9, -, ., _, ~, :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, %, and =. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. % can only be used in conjunction with url encoding as in %20), the RFC has all of these specifics.

I would highly recommend taking a look at datejs. With it's api, it becomes drop dead simple to add a month (and lots of other date functionality):

var one_month_from_your_date = your_date_object.add(1).month();

What's nice about datejs is that it handles edge cases, because technically you can do this using the native Date object and it's attached methods. But you end up pulling your hair out over edge cases, which datejs has taken care of for you.

Plus it's open source!

The three things that get installed that you will need to delete are:

1. Packages/modules
2. Scripts
3. Data files

Now on my linux system these live in:

1. /usr/lib/python2.5/site-packages
2. /usr/bin
3. /usr/share

But on a windows system they are more likely to be entirely within the Python distribution directory. I have no idea about OSX except it is more likey to follow the linux pattern.

I would like to say that you must always use jQuery latest or recent stable versions. However if you need to do some work with others versions then you can add that version and renamed the $ to some other name. For instance

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script>var $oldjQuery = $.noConflict(true);</script>

Look here if you write something using $ then you will get the latest version. But if you need to do anything with old then just use$oldjQuery instead of $.

Here is an example

$(function(){console.log($.fn.jquery)});
$oldjQuery (function(){console.log($oldjQuery.fn.jquery)})

NumPy has a numpy.mean which is an arithmetic mean. Usage is as simple as this:

>>> import numpy
>>> a = [1, 2, 4]
>>> numpy.mean(a)
2.3333333333333335

Splits an array in multiple arrays with a fixed maximum size.

public static <T extends Object> List<T[]> splitArray(T[] array, int max){

  int x = array.length / max;
  int r = (array.length % max); // remainder

  int lower = 0;
  int upper = 0;

  List<T[]> list = new ArrayList<T[]>();

  int i=0;

  for(i=0; i<x; i++){

    upper += max;

    list.add(Arrays.copyOfRange(array, lower, upper));

    lower = upper;
  }

  if(r > 0){

    list.add(Arrays.copyOfRange(array, lower, (lower + r)));

  }

  return list;
}

Example - an Array of 11 shall be splitted into multiple Arrays not exceeding a size of 5:

// create and populate an array
Integer[] arr = new Integer[11];

for(int i=0; i<arr.length; i++){
  arr[i] = i;
}

// split into pieces with a max. size of 5
List<Integer[]> list = ArrayUtil.splitArray(arr, 5);

// check
for(int i=0; i<list.size(); i++){

  System.out.println("Array " + i);

  for(int j=0; j<list.get(i).length; j++){
    System.out.println("  " + list.get(i)[j]);
  }
}

Output:

Array 0
  0
  1
  2
  3
  4
Array 1
  5
  6
  7
  8
  9
Array 2
  10

Since aa is the set/object that might be null, can you check aa == null ?

(aa / xx might be interchangeable (a typo in the question); the original question talks about xx but only defines aa)

i.e.

select new {
    AssetID = x.AssetID,
    Status = aa == null ? (bool?)null : aa.Online; // a Nullable<bool>
}

or if you want the default to be false (not null):

select new {
    AssetID = x.AssetID,
    Status = aa == null ? false : aa.Online;
}

Update; in response to the downvote, I've investigated more... the fact is, this is the right approach! Here's an example on Northwind:

        using(var ctx = new DataClasses1DataContext())
        {
            ctx.Log = Console.Out;
            var qry = from boss in ctx.Employees
                      join grunt in ctx.Employees
                          on boss.EmployeeID equals grunt.ReportsTo into tree
                      from tmp in tree.DefaultIfEmpty()
                      select new
                             {
                                 ID = boss.EmployeeID,
                                 Name = tmp == null ? "" : tmp.FirstName
                        };
            foreach(var row in qry)
            {
                Console.WriteLine("{0}: {1}", row.ID, row.Name);
            }
        }

And here's the TSQL - pretty much what we want (it isn't ISNULL, but it is close enough):

SELECT [t0].[EmployeeID] AS [ID],
    (CASE
        WHEN [t2].[test] IS NULL THEN CONVERT(NVarChar(10),@p0)
        ELSE [t2].[FirstName]
     END) AS [Name]
FROM [dbo].[Employees] AS [t0]
LEFT OUTER JOIN (
    SELECT 1 AS [test], [t1].[FirstName], [t1].[ReportsTo]
    FROM [dbo].[Employees] AS [t1]
    ) AS [t2] ON ([t0].[EmployeeID]) = [t2].[ReportsTo]
-- @p0: Input NVarChar (Size = 0; Prec = 0; Scale = 0) []
-- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1

QED?

You can use wget which is popular downloading shell tool for that. https://pypi.python.org/pypi/wget This will be the simplest method since it does not need to open up the destination file. Here is an example.

import wget
url = 'https://i1.wp.com/python3.codes/wp-content/uploads/2015/06/Python3-powered.png?fit=650%2C350'  
wget.download(url, '/Users/scott/Downloads/cat4.jpg') 

You can use a LinearLayout instead of using Button it's an arrangement i used in my app

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:background="@color/mainColor"
        android:orientation="horizontal"
        android:padding="10dp">

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="@drawable/ic_cv"
            android:textColor="@color/offBack"
            android:textSize="20dp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:text="@string/cartyCv"
            android:textColor="@color/offBack"
            android:textSize="25dp" />

    </LinearLayout>

just to add a detail to what Tamlyn wrote, instead of
$('form').get(0).setAttribute('action', 'baz'); //this works

$('form')[0].setAttribute('action', 'baz');
works equally well

There is a lot of ways to achieve this. In regards to the way you are asking, with a hidden form element.

create this form element inside your form:

<input type="hidden" name="total" value="">

So your form like this:

<form id="sampleForm" name="sampleForm" method="post" action="phpscript.php">
<input type="hidden" name="total" id="total" value="">
<a href="#" onclick="setValue();">Click to submit</a>
</form>

Then your javascript something like this:

<script>
function setValue(){
    document.sampleForm.total.value = 100;
    document.forms["sampleForm"].submit();
}
</script>

You could use a more generic converter

public class EnumBooleanConverter : IValueConverter
{
  #region IValueConverter Members
  public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
  {
    string parameterString = parameter as string;
    if (parameterString == null)
      return DependencyProperty.UnsetValue;

    if (Enum.IsDefined(value.GetType(), value) == false)
      return DependencyProperty.UnsetValue;

    object parameterValue = Enum.Parse(value.GetType(), parameterString);

    return parameterValue.Equals(value);
  }

  public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
  {
    string parameterString = parameter as string;
    if (parameterString == null)
        return DependencyProperty.UnsetValue;

    return Enum.Parse(targetType, parameterString);
  }
  #endregion
}

And in the XAML-Part you use:

<Grid>
    <Grid.Resources>
      <l:EnumBooleanConverter x:Key="enumBooleanConverter" />
    </Grid.Resources>
    <StackPanel >
      <RadioButton IsChecked="{Binding Path=VeryLovelyEnum, Converter={StaticResource enumBooleanConverter}, ConverterParameter=FirstSelection}">first selection</RadioButton>
      <RadioButton IsChecked="{Binding Path=VeryLovelyEnum, Converter={StaticResource enumBooleanConverter}, ConverterParameter=TheOtherSelection}">the other selection</RadioButton>
      <RadioButton IsChecked="{Binding Path=VeryLovelyEnum, Converter={StaticResource enumBooleanConverter}, ConverterParameter=YetAnotherOne}">yet another one</RadioButton>
    </StackPanel>
</Grid>

If the process is a child process and $BASHPID is not set, it is possible to query the ppid of a created child process of the running process. It might be a bit ugly, but it works. Example:

sleep 1 &
mypid=$(ps -o ppid= -p "$!")

When one of my VB.NET classes has all shared members I either convert it to a Module with a matching (or otherwise appropriate) namespace or I make the class not inheritable and not constructable:

Public NotInheritable Class MyClass1

   Private Sub New()
      'Contains only shared members.
      'Private constructor means the class cannot be instantiated.
   End Sub

End Class

Here's a little less opinionated version of the RawHTML function posted before. It lets you:

• configure the tag
• optionally replace newlines to <br />'s
• pass extra props that RawHTML will pass to the created element
• supply an empty string (RawHTML></RawHTML>)

Here's the component:

const RawHTML = ({ children, tag = 'div', nl2br = true, ...rest }) =>
    React.createElement(tag, {
        dangerouslySetInnerHTML: {
            __html: nl2br
                ? children && children.replace(/\n/g, '<br />')
                : children,
        },
        ...rest,
    });
RawHTML.propTypes = {
    children: PropTypes.string,
    nl2br: PropTypes.bool,
    tag: PropTypes.string,
};

Usage:

<RawHTML>{'First &middot; Second'}</RawHTML>
<RawHTML tag="h2">{'First &middot; Second'}</RawHTML>
<RawHTML tag="h2" className="test">{'First &middot; Second'}</RawHTML>
<RawHTML>{'first line\nsecond line'}</RawHTML>
<RawHTML nl2br={false}>{'first line\nsecond line'}</RawHTML>
<RawHTML></RawHTML>

Output:

<div>First · Second</div>
<h2>First · Second</h2>
<h2 class="test">First · Second</h2>
<div>first line<br>second line</div>
<div>first line
second line</div>
<div></div>

It will break on:

<RawHTML><h1>First &middot; Second</h1></RawHTML>

CXXFLAGS = -O3 -o prog -rdynamic -D_GNU_SOURCE -L./libmine

First ensure that hlsearch is enabled by issuing the following command

:set hlsearch

You can also add this to your .vimrc file as set

set hlsearch

now when you use the quick search mechanism in command mode or a regular search command, all results will be highlighted. To move forward between results, press 'n' to move backwards press 'N'

In normal mode, to perform a quick search for the word under the cursor and to jump to the next occurrence in one command press '*', you can also search for the word under the cursor and move to the previous occurrence by pressing '#'

In normal mode, quick search can also be invoked with the

/searchterm<Enter>

to remove highlights on ocuurences use, I have bound this to a shortcut in my .vimrc

:nohl

you could just use replace function before you return the string in the method

return df.format(bd).replace(",", ".")

Row(
 children: <Widget>[
  Flexible(
   child: TextFormField()),
  Container(width: 20, height: 20),
  Flexible(
   child: TextFormField())
 ])

This works for me, there are 3 widgets inside row: Flexible, Container, Flexible

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.

As Karthik mentioned, dct.keys() will work but it will return all the keys in dict_keys type not in list type. So if you want all the keys in a list, then list(dct.keys()) will work.

Instead of Windows PowerShell, find the item in the Start Menu called SharePoint 2013 Management Shell:

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

Intiate the above nodejs file in command prompt and the message "Server running at http://127.0.0.1:8081/" is displayed.Now in your browser type "http://127.0.0.1:8081/demo.html".

here you go

var str = "['abc',['def','ghi'],'jkl']";
//'[\'abc\',[\'def\',\'ghi\'],\'jkl\']'
str.replace(/[\[\]']/g,'' );
//'abc,def,ghi,jkl'

Google 'python += operator' leads you to http://docs.python.org/library/operator.html

Search for += once the page loads up for a more detailed answer.

Simplified example (with counter):

With Me.lstbox
    .ColumnCount = 2
    .ColumnWidths = "60;60"
    .AddItem
    .List(i, 0) = Company_ID
    .List(i, 1) = Company_name 
    i = i + 1

end with

Make sure to start the counter with 0, not 1 to fill up a listbox.

I needed an async csv reader and originally tried @Pransh Tiwari's answer but couldn't get it working with await and util.promisify(). Eventually I came across node-csvtojson, which pretty much does the same as csv-parser, but with promises. Here is an example usage of csvtojson in action:

const csvToJson = require('csvtojson');

const processRecipients = async () => {
    const recipients = await csvToJson({
        trim:true
    }).fromFile('./recipients.csv');

    // Code executes after recipients are fully loaded.
    recipients.forEach((recipient) => {
        console.log(recipient.name, recipient.email);
    });
};

Wrong:

case AnotherClass.MyEnum.VALUE_A

Right:

case VALUE_A:

The best way is to use simple math

>>> a = 8
>>> a**(1./3.)
2.0

EDIT

For Negative numbers

>>> a = -8
>>> -(-a)**(1./3.)
-2.0

Complete Program for all the requirements as specified

x = int(input("Enter an integer: "))
if x>0:
    ans = x**(1./3.)
    if ans ** 3 != abs(x):
        print x, 'is not a perfect cube!'
else:
    ans = -((-x)**(1./3.))
    if ans ** 3 != -abs(x):
        print x, 'is not a perfect cube!'

print 'Cube root of ' + str(x) + ' is ' + str(ans)

What you can try is to remove the map before initialising it or when you leave the page:

if(this.map) {
  this.map.remove();
}

The answer provided by rcs works and is simple. However, if you are handling larger datasets and need a performance boost there is a faster alternative:

library(data.table)
data = data.table(Category=c("First","First","First","Second","Third", "Third", "Second"), 
                  Frequency=c(10,15,5,2,14,20,3))
data[, sum(Frequency), by = Category]
#    Category V1
# 1:    First 30
# 2:   Second  5
# 3:    Third 34
system.time(data[, sum(Frequency), by = Category] )
# user    system   elapsed 
# 0.008     0.001     0.009 

Let's compare that to the same thing using data.frame and the above above:

data = data.frame(Category=c("First","First","First","Second","Third", "Third", "Second"),
                  Frequency=c(10,15,5,2,14,20,3))
system.time(aggregate(data$Frequency, by=list(Category=data$Category), FUN=sum))
# user    system   elapsed 
# 0.008     0.000     0.015 

And if you want to keep the column this is the syntax:

data[,list(Frequency=sum(Frequency)),by=Category]
#    Category Frequency
# 1:    First        30
# 2:   Second         5
# 3:    Third        34

The difference will become more noticeable with larger datasets, as the code below demonstrates:

data = data.table(Category=rep(c("First", "Second", "Third"), 100000),
                  Frequency=rnorm(100000))
system.time( data[,sum(Frequency),by=Category] )
# user    system   elapsed 
# 0.055     0.004     0.059 
data = data.frame(Category=rep(c("First", "Second", "Third"), 100000), 
                  Frequency=rnorm(100000))
system.time( aggregate(data$Frequency, by=list(Category=data$Category), FUN=sum) )
# user    system   elapsed 
# 0.287     0.010     0.296 

For multiple aggregations, you can combine lapply and .SD as follows

data[, lapply(.SD, sum), by = Category]
#    Category Frequency
# 1:    First        30
# 2:   Second         5
# 3:    Third        34

for those looking for a way to mock POST HttpServletRequest with Json payload, the below is in Kotlin, but the key take away here is the DelegatingServetInputStream when you want to mock the request.getInputStream from the HttpServletRequest

@Mock
private lateinit var request: HttpServletRequest

@Mock
private lateinit var response: HttpServletResponse

@Mock
private lateinit var chain: FilterChain

@InjectMocks
private lateinit var filter: ValidationFilter


@Test
fun `continue filter chain with valid json payload`() {
    val payload = """{
      "firstName":"aB",
      "middleName":"asdadsa",
      "lastName":"asdsada",
      "dob":null,
      "gender":"male"
    }""".trimMargin()

    whenever(request.requestURL).
        thenReturn(StringBuffer("/profile/personal-details"))
    whenever(request.method).
        thenReturn("PUT")
    whenever(request.inputStream).
        thenReturn(DelegatingServletInputStream(ByteArrayInputStream(payload.toByteArray())))

    filter.doFilter(request, response, chain)

    verify(chain).doFilter(request, response)
}

I know it's not an answer to the exact question asked, but I found this question looking to diff a file in a branch and a local uncommitted file and I figured I would share

Syntax:

git diff <commit-ish>:./ -- <path>

Examples:

git diff origin/master:./ -- README.md
git diff HEAD^:./ -- README.md
git diff stash@{0}:./ -- README.md
git diff 1A2B3C4D:./ -- README.md

(Thanks Eric Boehs for a way to not have to type the filename twice)

Your for loop has no loop body:

elif option == 2:
    print "please enter a number"
    for x in range(x, 1, 1):
elif option == 0:

Actually, the whole if option == 1: block has indentation problems. elif option == 2: should be at the same level as the if statement.

There is simple way to do it if you fear Javascript...I'm still learning. Open Street makes a simple Wordpress plugin you can customize. Add OSM Widget plugin.

This will be a filler until I figure out my Python Java concotion using coverter TIGER line files from the Census Bureau.

select * from table_name where id=5 and column_name not in ('sandy,'pandy');

You need a Python DictReader class. More help can be found from here

import csv

with open('file_name.csv', 'rt') as f:
    reader = csv.DictReader(f)
    for row in reader:
        print row

 public boolean isPalindrom(String text) {
    StringBuffer stringBuffer = new StringBuffer(text);
     return stringBuffer.reverse().toString().equals(text);
}

"On Windows and Mac OS X, the CPython installers now default to installing pip along with CPython itself (users may opt out of installing it during the installation process). Window users will need to opt in to the automatic PATH modifications to have pip available from the command line by default, otherwise it can still be accessed through the Python launcher for Windows as py -m pip."

Have you tried it?

in case of a similar issue when I'm creating dockerfile I faced the same scenario:- I used below changed in mysql_connect function as:-

if($CONN = @mysqli_connect($DBHOST, $DBUSER, $DBPASS)){ //mysql_query("SET CHARACTER SET 'gbk'", $CONN);

For Bootstrap 3 and 4 it's

.collapsing {
    -webkit-transition: none;
    transition: none;
    display: none;
}

So I did some tests with sqlite for very large files, and came to some conclusions (at least for my specific application).

The tests involve a single sqlite file with either a single table, or multiple tables. Each table had about 8 columns, almost all integers, and 4 indices.

The idea was to insert enough data until sqlite files were about 50GB.

Single Table

I tried to insert multiple rows into a sqlite file with just one table. When the file was about 7GB (sorry I can't be specific about row counts) insertions were taking far too long. I had estimated that my test to insert all my data would take 24 hours or so, but it did not complete even after 48 hours.

This leads me to conclude that a single, very large sqlite table will have issues with insertions, and probably other operations as well.

I guess this is no surprise, as the table gets larger, inserting and updating all the indices take longer.

Multiple Tables

I then tried splitting the data by time over several tables, one table per day. The data for the original 1 table was split to ~700 tables.

This setup had no problems with the insertion, it did not take longer as time progressed, since a new table was created for every day.

Vacuum Issues

As pointed out by i_like_caffeine, the VACUUM command is a problem the larger the sqlite file is. As more inserts/deletes are done, the fragmentation of the file on disk will get worse, so the goal is to periodically VACUUM to optimize the file and recover file space.

However, as pointed out by documentation, a full copy of the database is made to do a vacuum, taking a very long time to complete. So, the smaller the database, the faster this operation will finish.

Conclusions

For my specific application, I'll probably be splitting out data over several db files, one per day, to get the best of both vacuum performance and insertion/delete speed.

This complicates queries, but for me, it's a worthwhile tradeoff to be able to index this much data. An additional advantage is that I can just delete a whole db file to drop a day's worth of data (a common operation for my application).

I'd probably have to monitor table size per file as well to see when the speed will become a problem.

It's too bad that there doesn't seem to be an incremental vacuum method other than auto vacuum. I can't use it because my goal for vacuum is to defragment the file (file space isn't a big deal), which auto vacuum does not do. In fact, documentation states it may make fragmentation worse, so I have to resort to periodically doing a full vacuum on the file.

This worked for me-

if(Mage::registry('current_product')->getTypeId() == 'simple' ) {

Use getTypeId()

Looking at my system's menu.vim (look for 'Color Scheme submenu') and @chappar's answer, I came up with the following function:

" Returns the list of available color schemes
function! GetColorSchemes()
   return uniq(sort(map(
   \  globpath(&runtimepath, "colors/*.vim", 0, 1),  
   \  'fnamemodify(v:val, ":t:r")'
   \)))
endfunction

It does the following:

1. Gets the list of available color scheme scripts under all runtime paths (globpath, runtimepath)
2. Maps the script paths to their base names (strips parent dirs and extension) (map, fnamemodify)
3. Sorts and removes duplicates (uniq, sort)

Then to use the function I do something like this:

let s:schemes = GetColorSchemes()
if index(s:schemes, 'solarized') >= 0
   colorscheme solarized
elseif index(s:schemes, 'darkblue') >= 0
   colorscheme darkblue
endif

Which means I prefer the 'solarized' and then the 'darkblue' schemes; if none of them is available, do nothing.

git fetch will resolve this for you

If my understanding is correct, your local (cached) origin/master is out of date. This command will update the repository state from the server.

see ?tail and ?head for some convenient functions:

> x <- 1:10
> tail(x,5)
[1]  6  7  8  9 10

For the argument's sake : everything but the last five elements would be :

> head(x,n=-5)
[1] 1 2 3 4 5

As @Martin Morgan says in the comments, there are two other possibilities which are faster than the tail solution, in case you have to carry this out a million times on a vector of 100 million values. For readibility, I'd go with tail.

test                                        elapsed    relative 
tail(x, 5)                                    38.70     5.724852     
x[length(x) - (4:0)]                           6.76     1.000000     
x[seq.int(to = length(x), length.out = 5)]     7.53     1.113905     

benchmarking code :

require(rbenchmark)
x <- 1:1e8
do.call(
  benchmark,
  c(list(
    expression(tail(x,5)),
    expression(x[seq.int(to=length(x), length.out=5)]),
    expression(x[length(x)-(4:0)])
  ),  replications=1e6)
)

Just use:

<?php
    include("/path/to/file.html");
?>

That will echo it as well. This also has the benefit of executing any PHP in the file.

If you need to do anything with the contents, use file_get_contents(),

For example,

<?php
    $pagecontents = file_get_contents("/path/to/file.html");

    echo str_replace("Banana", "Pineapple", $pagecontents);

?>

This doesn't execute code in that file, so be careful if you expect that to work.

I usually use:

include($_SERVER['DOCUMENT_ROOT']."/path/to/file/as/in/url.html");

as then I can move files without breaking the includes.

library(lubridate) if your date format is like this '04/24/2017 05:35:00'then change it like below prods.all$Date2<-gsub("/","-",prods.all$Date2) then change the date format parse_date_time(prods.all$Date2, orders="mdy hms")

If you know the target paper size, you can place your content in a DIV with that specific size and add a margin to that DIV to simulate the print margin. Unfortunately, I don't believe you have extra control over the print functionality apart from just show the print dialog box.

Python3

use

from .user import User inside dir.py file

and

use from class.dir import Dir inside main.py
or from class.usr import User inside main.py

like so

add this to your css

.table-vcenter td {
   vertical-align: middle!important;
}

then add to the class to your table:

        <table class="table table-hover table-striped table-vcenter">

maybe this plugin may be useful: http://www.farinspace.com/jquery-image-preload-plugin/

You can use ref.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {}
  },
  template: `
  <div>
     <ChildForm :item="item" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.$refs.form.submit()
    }
  },
  components: { ChildForm },
})

If you dislike tight coupling, you can use Event Bus as shown by @Yosvel Quintero. Below is another example of using event bus by passing in the bus as props.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {},
    bus: new Vue(),
  },
  template: `
  <div>
     <ChildForm :item="item" :bus="bus" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.bus.$emit('submit')
    }
  },
  components: { ChildForm },
})

Code of component.

<template>
 ...
</template>

<script>
export default {
  name: 'NowForm',
  props: ['item', 'bus'],
  methods: {
    submit() {
        ...
    }
  },
  mounted() {
    this.bus.$on('submit', this.submit)
  },  
}
</script>

https://code.luasoftware.com/tutorials/vuejs/parent-call-child-component-method/

void abc(void *a, int b) {
  char *format[] = {"%d", "%c", "%f"};
  printf(format[b-1], a);
}

Neither code is always better. They do different things, so they are good at different things.

InvariantCultureIgnoreCase uses comparison rules based on english, but without any regional variations. This is good for a neutral comparison that still takes into account some linguistic aspects.

OrdinalIgnoreCase compares the character codes without cultural aspects. This is good for exact comparisons, like login names, but not for sorting strings with unusual characters like é or ö. This is also faster because there are no extra rules to apply before comparing.

was a lot of great answers provided however I found some performance shortcomings, so let me offer a version with performance in mind. Every constant is precalculated and x,y variables are introduced to avoid calculating the same value twice. Hope it helps

    private static final double r2d = 180.0D / 3.141592653589793D;
    private static final double d2r = 3.141592653589793D / 180.0D;
    private static final double d2km = 111189.57696D * r2d;
    public static double meters(double lt1, double ln1, double lt2, double ln2) {
        double x = lt1 * d2r;
        double y = lt2 * d2r;
        return Math.acos( Math.sin(x) * Math.sin(y) + Math.cos(x) * Math.cos(y) * Math.cos(d2r * (ln1 - ln2))) * d2km;
    }

Here's a solution that may work better in the case you are referencing objWorksheet.UsedRange.

Excel.Worksheet mySheet = ...(load a workbook, etc);
Excel.Range myRange = mySheet.UsedRange;
var values = (myRange.Value as Object[,]);
int rowNumber = 3, columnNumber = 5;
string cellValue = Convert.ToString(values[rowNumber, columnNumber]);

I want to change the width and height of a div. data attributes did not change it. Instead I use:

var size = $("#theme_photo_size").val().split("x");
$("#imageupload_img").width(size[0]);
$("#imageupload_img").attr("data-width", size[0]);
$("#imageupload_img").height(size[1]);
$("#imageupload_img").attr("data-height", size[1]);

be careful:

$("#imageupload_img").data("height", size[1]); //did not work

did not set it

$("#imageupload_img").attr("data-height", size[1]); // yes it worked!

this has set it.

Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java.

This example might help you out: https://webblocks.nl/tests/ajax/file-drag-drop.html

(It also includes the drag/drop interface but that's easily ignored.)

Basically what it comes down to is this:

<input id="files" type="file" />

<script>
document.getElementById('files').addEventListener('change', function(e) {
    var file = this.files[0];
    var xhr = new XMLHttpRequest();
    (xhr.upload || xhr).addEventListener('progress', function(e) {
        var done = e.position || e.loaded
        var total = e.totalSize || e.total;
        console.log('xhr progress: ' + Math.round(done/total*100) + '%');
    });
    xhr.addEventListener('load', function(e) {
        console.log('xhr upload complete', e, this.responseText);
    });
    xhr.open('post', '/URL-HERE', true);
    xhr.send(file);
});
</script>

(demo: http://jsfiddle.net/rudiedirkx/jzxmro8r/)

So basically what it comes down to is this =)

xhr.send(file);

Where file is typeof Blob: http://www.w3.org/TR/FileAPI/

Another (better IMO) way is to use FormData. This allows you to 1) name a file, like in a form and 2) send other stuff (files too), like in a form.

var fd = new FormData;
fd.append('photo1', file);
fd.append('photo2', file2);
fd.append('other_data', 'foo bar');
xhr.send(fd);

FormData makes the server code cleaner and more backward compatible (since the request now has the exact same format as normal forms).

All of it is not experimental, but very modern. Chrome 8+ and Firefox 4+ know what to do, but I don't know about any others.

This is how I handled the request (1 image per request) in PHP:

if ( isset($_FILES['file']) ) {
    $filename = basename($_FILES['file']['name']);
    $error = true;

    // Only upload if on my home win dev machine
    if ( isset($_SERVER['WINDIR']) ) {
        $path = 'uploads/'.$filename;
        $error = !move_uploaded_file($_FILES['file']['tmp_name'], $path);
    }

    $rsp = array(
        'error' => $error, // Used in JS
        'filename' => $filename,
        'filepath' => '/tests/uploads/' . $filename, // Web accessible
    );
    echo json_encode($rsp);
    exit;
}

You could use a library such as node-uuid for this to make sure you get unique ids.

Install using:

npm install node-uuid --save

Then in your react component add the following:

import {default as UUID} from "node-uuid";
import {default as React} from "react";

export default class MyComponent extends React.Component {   
  componentWillMount() {
    this.id = UUID.v4();
  }, 
  render() {
    return (
      <div>
        <label htmlFor={this.id}>My label</label>
        <input id={this.id} type="text"/>
      </div>
    );
  }   
}

When something happens in my view I fire off an event that my activity is listening for:

// DECLARED IN (CUSTOM) VIEW

    private OnScoreSavedListener onScoreSavedListener;
    public interface OnScoreSavedListener {
        public void onScoreSaved();
    }
    // ALLOWS YOU TO SET LISTENER && INVOKE THE OVERIDING METHOD 
    // FROM WITHIN ACTIVITY
    public void setOnScoreSavedListener(OnScoreSavedListener listener) {
        onScoreSavedListener = listener;
    }

// DECLARED IN ACTIVITY

    MyCustomView slider = (MyCustomView) view.findViewById(R.id.slider)
    slider.setOnScoreSavedListener(new OnScoreSavedListener() {
        @Override
        public void onScoreSaved() {
            Log.v("","EVENT FIRED");
        }
    });

If you want to know more about communication (callbacks) between fragments see here: http://developer.android.com/guide/components/fragments.html#CommunicatingWithActivity

I know this is an old question, but for anyone who have the same issue there is a newer and simpler solution: an "appendTo" option has been introduced in jQuery UI 1.10.0

http://api.jqueryui.com/dialog/#option-appendTo

$("#dialog").dialog({
    appendTo: "form"
    ....
});

Assuming you don't know anything about the variable in question, you should take this approach:

if(typeof data === 'number') {
    var remainder = (data % 1);
    if(remainder === 0) {
        // yes, it is an integer
    }
    else if(isNaN(remainder)) {
        // no, data is either: NaN, Infinity, or -Infinity
    }
    else {
        // no, it is a float (still a number though)
    }
}
else {
    // no way, it is not even a number
}

To put it simply:

if(typeof data==='number' && (data%1)===0) {
    // data is an integer
}

I have used DTS (now known as SQL server Import and Export Wizard). I used the this tutorial which worked great for me even in Sql 2008 and excel 2010 (14.0)

I hope this helps

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

For example, if you want an array of int pointers it will be int* a[10]. It means that variable a is a collection of 10 int* s.

EDIT

I guess this is what you want to do:

class Bar
{
};

class Foo
{
public:

    //Takes number of bar elements in the pointer array
    Foo(int size_in);

    ~Foo();
    void add(Bar& bar);
private:

    //Pointer to bar array
    Bar** m_pBarArr;

    //Current fee bar index
    int m_index;
};

Foo::Foo(int size_in) : m_index(0)
{
    //Allocate memory for the array of bar pointers
    m_pBarArr = new Bar*[size_in];
}

Foo::~Foo()
{
    //Notice delete[] and not delete
    delete[] m_pBarArr;
    m_pBarArr = NULL;
}

void Foo::add(Bar &bar)
{
    //Store the pointer into the array. 
    //This is dangerous, you are assuming that bar object
    //is valid even when you try to use it
    m_pBarArr[m_index++] = &bar;
}

Honestly, I'd recommend using phpseclib, a pure PHP SSH2 implementation. Example:

<?php
include('Net/SSH2.php');

$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
    exit('Login Failed');
}

echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>

It's a ton more portable, easier to use and more feature packed too.

The magic happens in onOptionsItemSelected.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            // app icon in action bar clicked; go home
            Intent intent = new Intent(this, HomeActivity.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

As Aaron has already pointed out, you can set delete behaviour to CASCADE and that will delete children records when a parent record is deleted. Unless you want some sort of other magic to happen (in which case points 2, 3 of Aaron's reply would be useful), I don't see why would you need to delete with inner joins.

Unfortunately the best way would be to check for that directory. I am not sure what you mean but "actually installed" as .NET 3.5 uses the same CLR as .NET 3.0 and .NET 2.0 so all new functionality is wrapped up in new assemblies that live in that directory. Basically, if the directory is there then 3.5 is installed.

Only thing I would add is to find the dir this way for maximum flexibility:

%windir%\Microsoft.NET\Framework\v3.5

Use upper-case HH for 24h format:

String s = curr.ToString("HH:mm");

See DateTime.ToString Method.

You could try a different approach like read the file line by line instead of dealing with all this nl2br / explode stuff.

$fh = fopen("employees.txt", "r"); if ($fh) {     while (($line = fgets($fh)) !== false) {         $line = trim($line);         echo "<option value='".$line."'>".$line."</option>";     } } else {     // error opening the file, do something } 

Also maybe just doing a trim (remove whitespace from beginning/end of string) is your issue?

And maybe people are just misunderstanding what you mean by "submitting results to a spreadsheet" -- are you doing this with code? or a copy/paste from an HTML page into a spreadsheet? Maybe you can explain that in more detail. The delimiter for which you split the lines of the file shouldn't be displaying in the output anyway unless you have unexpected output for some other reason.

Octave is basically an open source version of MATLAB. It was written to be just that. MATLAB has a very nice GUI which makes it a bit easier to use but the next stable release of OCTAVE will also have a GUI, which I have tested in the unstable release, and looks fantastic. Octave is much more buggy because it was developed and maintained by a group of volunteers, where the development of MATLAB is funded by millions of dollars by industry. I'm still a student and am using a student version of MATLAB, but I am thinking of going over to Octave once the stable version with the GUI is released.

MATLAB is probably a lot more powerful than Octave, and the algorithms run faster, but for most applications, Octave is more than adequate and is, in my opinion' an amazing tool that is completely free, where Octave is completely free.

I would say use MATLAB while you can use the academic version, but the switch to Octave should be seamless as they use the exact same syntax.

Lastly, there is the issue of SIMULINK. If you want to do simulation or control system design (there are probably a million other uses) SIMULINK is fantastic and comes with MATLAB. I don't think any other comes close to this, although Scilab is apparently a 'good' open source alternative, I haven't tried it.

Peace.

Just to add this to the list:

Uri.EscapeUriString("Hi there+Hello there") // Hi%20there+Hello%20there
Uri.EscapeDataString("Hi there+Hello there") // Hi%20there%2BHello%20there

See https://stackoverflow.com/a/34189188/98491

Usually you want to use EscapeDataString which does it right.

to build on what Martin Kuzdowicz posted above. I use the following to do an update using mongoose and a deep merge of json objects. Along with the model.save() function in mongoose this allows mongoose to do a full validation even one that relies on other values in the json. it does require the deepmerge package https://www.npmjs.com/package/deepmerge. But that is a very light weight package.

var merge = require('deepmerge');

app.put('url', (req, res) => {

    const modelId = req.body.model_id;

    MyModel.findById(modelId).then((model) => {
        return Object.assign(model, merge(model.toObject(), req.body));
    }).then((model) => {
        return model.save();
    }).then((updatedModel) => {
        res.json({
            msg: 'model updated',
            updatedModel
        });
    }).catch((err) => {
        res.send(err);
    });
});

I am adding two sollution that work for me.

1st sollution is:

1. Open database.php file insde config dir/folder.

2. Edit 'engine' => null, to 'engine' => 'InnoDB',

   This worked for me.

2nd sollution is:

1. Open database.php file insde config dir/folder.
   2.Edit
   'charset' => 'utf8mb4', 'collation' => 'utf8mb4_unicode_ci',
   to
   

   'charset' => 'utf8', 'collation' => 'utf8_unicode_ci',

Goodluck

It should be a Python expression that, when eval'd, creates an object with the exact same properties as this one. For example, if you have a Fraction class that contains two integers, a numerator and denominator, your __repr__() method would look like this:

# in the definition of Fraction class
def __repr__(self):
    return "Fraction(%d, %d)" % (self.numerator, self.denominator)

Assuming that the constructor takes those two values.

I read through this question, and feel the best way to implement useEffect is not mentioned in the answers. Let's say you have a network call, and would like to do something once you have the response. For the sake of simplicity, let's store the network response in a state variable. One might want to use action/reducer to update the store with the network response.

const [data, setData] = useState(null);

/* This would be called on initial page load */
useEffect(()=>{
    fetch(`https://www.reddit.com/r/${subreddit}.json`)
    .then(data => {

It's in your home folder but it's hidden by default.

Typing the below commands in the terminal made it visible for me (only the .m2 folder that is, not all the other hidden folders).

> mv ~/.m2 ~/m2
> ln -s ~/m2 ~/.m2

just use

$memcachedConfig = array();

before

 print $memcachedConfig['host'];
 print $memcachedConfig['port'];


 Warning: Illegal string offset 'host' in ....
 Warning: Illegal string offset 'port' in ....

this is because you never define what is $memcachedConfig, so by default are treated by string not arrays..

Right click on the project

->Run As --> Run configurations.

Then select Maven Build

Then click new button to create a configuration of the selected type. Click on Browse workspace (now is Workspace...) then select your project and in goals specify eclipse:eclipse

if(list.ElementAtOrDefault(2) != null)
{
   // logic
}

ElementAtOrDefault() is part of the System.Linq namespace.

Although you have a List, so you can use list.Count > 2.

function listCookies() {
    let cookies = document.cookie.split(';')
    cookies.map((cookie, n) => console.log(`${n}:`, decodeURIComponent(cookie)))
}

function findCookie(e) {
  let cookies = document.cookie.split(';')
  cookies.map((cookie, n) => cookie.includes(e) && console.log(decodeURIComponent(cookie), n))
}

This is specifically for the window you're in. Tried to keep it clean and concise.

As of 13 April 2020 there is no such functionality unless you are able to use different scopes, but you may use the postinstall script as a workaround. It is always executed, well, after each npm install:

Say you have your .npmrc configured to install @foo-org/foo-pack-private from your private github repo, but the @foo-org/foo-pack-public public package is on npm (under the same scope: foo-org).

Your postinstall might look like this:

"scripts": {
    ...
    "postinstall": "mv .npmrc .npmrcc && npm i @foo-org/foo-pack --dry-run && mv .npmrcc .npmrc".
}

Don't forget to remove @foo-pack/foo-org from the dependencies array to make sure npm install does not try and get it from github and to add the --dry-run flag that makes sure package.json and package-lock.json stay unchanged after npm install.

I was having this same problem and doing some checks my script was just simply not getting the sessionid cookie.

I figured out by looking at the sessionid cookie value in the browser that my framework (Django) was passing the sessionid cookie with HttpOnly as default. This meant that scripts did not have access to the sessionid value and therefore were not passing it along with requests. Kind of ridiculous that HttpOnly would be the default value when so many things use Ajax which would require access restriction.

To fix this I changed a setting (SESSION_COOKIE_HTTPONLY=False) but in other cases it may be a "HttpOnly" flag on the cookie path

I didn't need the full JDK, I just needed to make JRE work and none of the other answers provided above worked for me. Maybe it used to work, but now (1st Jul 2018) it isn't working. I just kept getting the error and the pop-up.

I eventually solved this issue by placing the following JAVA_HOME export in ~/.bash_profile:

export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

Hope this helps someone. I'm running Mac OS High Sierra.

1. Right click the folder, click on Properties.
2. Click on the Security tab
3. Add the name Everyone to the user list.

I use linux and the answers did not help me.
I had to erase the folder ~/.config/smartgit to make it work again. This is what the documentation is saying

Default Location of SmartGit's Settings Directory
Windows %APPDATA%\syntevo\SmartGit\ (%APPDATA% is the path defined in the environment variable APPDATA)
Mac OS ~/Library/Preferences/SmartGit/ (the Finder might not show the ~/Libraries directory by default, but you can invoke open ~/Library from a terminal)
Linux/Unix ${XDG_CONFIG_HOME}/smartgit/ (if the environment variable XDG_CONFIG_HOME is not defined, ~/.config is used instead)

You can try this also to replace existing object

toDoTaskList = [
                {id:'abcd', name:'test'},
                {id:'abcdc', name:'test'},
                {id:'abcdtr', name:'test'}
              ];

newRecordToUpdate = {id:'abcdc', name:'xyz'};
this.toDoTaskList.map((todo, i) => {
         if (todo.id == newRecordToUpdate .id){
            this.toDoTaskList[i] = updatedVal;
          }
        });

As per the documentation, most browsers will display the <ul>, <ol> and <li> elements with the following default values:

Default CSS settings for UL or OL tag:

ul, ol { 
    display: block;
    list-style: disc outside none;
    margin: 1em 0;
    padding: 0 0 0 40px;
}
ol { 
    list-style-type: decimal;
}

Default CSS settings for LI tag:

li { 
    display: list-item;
}

Style nested list items as well:

ul ul, ol ul {
    list-style-type: circle;
    margin-left: 15px; 
}
ol ol, ul ol { 
    list-style-type: lower-latin;
    margin-left: 15px; 
}

Note: The result will be perfect if we use the above styles with a class. Also see different List-Item markers.

$(window).height();

To set anything in the middle you can use CSS.

<style>
#divCentre 
{ 
    position: absolute;
    left: 50%;
    top: 50%;
    width: 300px;
    height: 400px;
    margin-left: -150px;
    margin-top: -200px;
}
</style>
<div id="divCentre">I am at the centre</div>

Local Storage Set Item

Syntax:

  localStorage.setItem(key,value);
  localStorage.getItem(key);

Example:

  localStorage.setItem("name","Muthu");
  if(localStorage){   //it checks browser support local storage or not
    let Name=localStorage.getItem("name");
    if(Name!=null){  //  it checks values here or not to the variable
       //do some stuff here...
    }
  }

also you can use

    localStorage.setItem("name", JSON.stringify("Muthu"));

Session Storage Set Item

Syntax:

  sessionStorage.setItem(key,value);
  sessionStorage.getItem(key);

Example:

  sessionStorage.setItem("name","Muthu");

  if(sessionStorage){ //it checks browser support session storage/not
    let Name=sessionStorage.getItem("name");

    if(Name!=null){  //  it checks values here or not to the variable
       //do some stuff here...
    }
  }

also you can use

   sessionStorage.setItem("name", JSON.stringify("Muthu"));

If you do this a lot, NumPy is the way to go.

If for some reason you can't use NumPy:

Use Fake sendmail for Windows to send mail.

1. Create a folder named sendmail in C:\wamp\.
2. Extract these 4 files in sendmail folder: sendmail.exe, libeay32.dll, ssleay32.dll and sendmail.ini.
3. Then configure C:\wamp\sendmail\sendmail.ini:

smtp_server=smtp.gmail.com
smtp_port=465
[email protected]
auth_password=your_password

4. The above will work against a Gmail account. And then configure php.ini:

   sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"

5. Now, restart Apache, and that is basically all you need to do.

I have custom a dashline which support horizontal&verical dash line . code below:

public class DashedLineView extends View
{
private float density;
private Paint paint;
private Path path;
private PathEffect effects;

public DashedLineView(Context context)
{
    super(context);
    init(context);
}

public DashedLineView(Context context, AttributeSet attrs)
{
    super(context, attrs);
    init(context);
}

public DashedLineView(Context context, AttributeSet attrs, int defStyle)
{
    super(context, attrs, defStyle);
    init(context);
}

private void init(Context context)
{
    density = DisplayUtil.getDisplayDensity(context);
    paint = new Paint();
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth(density * 4);
    //set your own color
    paint.setColor(context.getResources().getColor(R.color.XXX));
    path = new Path();
    //array is ON and OFF distances in px (4px line then 2px space)
    effects = new DashPathEffect(new float[] { 4, 2, 4, 2 }, 0);

}

@Override
protected void onDraw(Canvas canvas)
{
    // TODO Auto-generated method stub
    super.onDraw(canvas);
    paint.setPathEffect(effects);
    int measuredHeight = getMeasuredHeight();
    int measuredWidth = getMeasuredWidth();
    if (measuredHeight <= measuredWidth)
    {
        // horizontal
        path.moveTo(0, 0);
        path.lineTo(measuredWidth, 0);
        canvas.drawPath(path, paint);
    }
    else
    {
        // vertical
        path.moveTo(0, 0);
        path.lineTo(0, measuredHeight);
        canvas.drawPath(path, paint);
    }

}
}

All the tips did not work for me using the Gaisler Tools for GR712RC Installation for OS RTEMS. I'm using the Eclipse Kepler.

The simple way was making a copy of sparc-rtems-gcc.exe to gcc.exe, and sparc-rtems-g++.exe to g++.exe, in the C:\opt\rtems-4.10-mingw\bin directory.

Use a final class. for simplicity you may then use a static import to reuse your values in another class

public final class MyValues {
  public static final String VALUE1 = "foo";
  public static final String VALUE2 = "bar";
}

in another class :

import static MyValues.*
//...

if(variable.equals(VALUE1)){
//...
}

In Jelly.core to test a literal string one would use:

<core:when test="${ name == 'ABC' }"> 

But if I have to check for string "Toy's R Us":

<core:when test="${ name == "Toy's R Us" }">

It would be like this, if the double quotes were allowed inside:

<core:when test="${ name == "Toy's R Us" }"> 

I solved this by setting a higher timeout value for the proxy:

location / {
    proxy_read_timeout 300s;
    proxy_connect_timeout 75s;
    proxy_pass http://localhost:3000;
}

This works for me on OSX.

With the help of spark-csv we can write to a CSV file.

val dfsql = sqlContext.sql("select * from tablename")
dfsql.write.format("com.databricks.spark.csv").option("header","true").save("output.csv")`

This shorter one requires no temporary file, it is immune to multiple insertions, and it lets you change the schedule of an existing entry.

Say you have these:

croncmd="/home/me/myfunction myargs > /home/me/myfunction.log 2>&1"
cronjob="0 */15 * * * $croncmd"

To add it to the crontab, with no duplication:

( crontab -l | grep -v -F "$croncmd" ; echo "$cronjob" ) | crontab -

To remove it from the crontab whatever its current schedule:

( crontab -l | grep -v -F "$croncmd" ) | crontab -

Notes:

• grep -F matches the string literally, as we do not want to interpret it as a regular expression
• We also ignore the time scheduling and only look for the command. This way; the schedule can be changed without the risk of adding a new line to the crontab

Another thing that people may find useful when using the develop method is the --user option to install without sudo. Ex:

python setup.py develop --user

instead of

sudo python setup.py develop

^M is carriage return. You can do this:

$str =~ s/\r//g

It's not bad to use a wild card with a Java import statement.

In Clean Code, Robert C. Martin actually recommends using them to avoid long import lists.

Here is the recommendation:

J1: Avoid Long Import Lists by Using Wildcards

If you use two or more classes from a package, then import the whole package with

import package.*;

Long lists of imports are daunting to the reader. We don’t want to clutter up the tops of our modules with 80 lines of imports. Rather we want the imports to be a concise statement about which packages we collaborate with.

Specific imports are hard dependencies, whereas wildcard imports are not. If you specifically import a class, then that class must exist. But if you import a package with a wildcard, no particular classes need to exist. The import statement simply adds the package to the search path when hunting for names. So no true dependency is created by such imports, and they therefore serve to keep our modules less coupled.

There are times when the long list of specific imports can be useful. For example, if you are dealing with legacy code and you want to find out what classes you need to build mocks and stubs for, you can walk down the list of specific imports to find out the true qualified names of all those classes and then put the appropriate stubs in place. However, this use for specific imports is very rare. Furthermore, most modern IDEs will allow you to convert the wildcarded imports to a list of specific imports with a single command. So even in the legacy case it’s better to import wildcards.

Wildcard imports can sometimes cause name conflicts and ambiguities. Two classes with the same name, but in different packages, will need to be specifically imported, or at least specifically qualified when used. This can be a nuisance but is rare enough that using wildcard imports is still generally better than specific imports.

var shuffledArray = function(inpArr){
    //inpArr - is input array
    var arrRand = []; //this will give shuffled array
    var arrTempInd = []; // to store shuffled indexes
    var max = inpArr.length;
    var min = 0;
    var tempInd;
    var i = 0;

    do{
        //generate random index between range
        tempInd = Math.floor(Math.random() * (max - min));
        //check if index is already available in array to avoid repetition
        if(arrTempInd.indexOf(tempInd)<0){
            //push character at random index
            arrRand[i] = inpArr[tempInd];
            //push random indexes
            arrTempInd.push(tempInd);
            i++;
        }
    }
    // check if random array length is equal to input array length
    while(arrTempInd.length < max){
        return arrRand; // this will return shuffled Array
    }
};

Just pass the array to function and in return get the shuffled array

You need to use the group(int) of your matcher - group(0) is the entire match, and group(1) is the first group you marked. In the example you specify, group(1) is what comes after "sentence".

Use this

$ dig +short stackoverflow.com

Just add the attribute disabled to the element (or use jQuery to do it for you). Disabled prevents the input from being focused or selected at all.

I was really looking for a way to fetch the connection status of a device, not listen to connection events. Here's what worked for me:

BluetoothManager bm = (BluetoothManager) context.getSystemService(Context.BLUETOOTH_SERVICE);
List<BluetoothDevice> devices = bm.getConnectedDevices(BluetoothGatt.GATT);
int status = -1;

for (BluetoothDevice device : devices) {
  status = bm.getConnectionState(device, BLuetoothGatt.GATT);
  // compare status to:
  //   BluetoothProfile.STATE_CONNECTED
  //   BluetoothProfile.STATE_CONNECTING
  //   BluetoothProfile.STATE_DISCONNECTED
  //   BluetoothProfile.STATE_DISCONNECTING
}

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."

An extra pair of rabbits' ears should do the trick.

start "" "C:\Program...

START regards the first quoted parameter as the window-title, unless it's the only parameter - and any switches up until the executable name are regarded as START switches.

If someone wants to implement using directives then, identify (or create) a div in the index.html (just under the body tag, or at same DOM level)

<div class="google-analytics"/>

and then add the following code in the directive

myApp.directive('googleAnalytics', function ( $location, $window ) {
  return {
    scope: true,
    link: function (scope) {
      scope.$on( '$routeChangeSuccess', function () {
        $window._gaq.push(['_trackPageview', $location.path()]);
      });
    }
  };
});

Here is my CORS middleware:

<?php namespace App\Http\Middleware;

use Closure;

class CORS {

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {

        header("Access-Control-Allow-Origin: *");

        // ALLOW OPTIONS METHOD
        $headers = [
            'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',
            'Access-Control-Allow-Headers'=> 'Content-Type, X-Auth-Token, Origin'
        ];
        if($request->getMethod() == "OPTIONS") {
            // The client-side application can set only headers allowed in Access-Control-Allow-Headers
            return Response::make('OK', 200, $headers);
        }

        $response = $next($request);
        foreach($headers as $key => $value)
            $response->header($key, $value);
        return $response;
    }

}

To use CORS middleware you have to register it first in your app\Http\Kernel.php file like this:

protected $routeMiddleware = [
        //other middlewares
        'cors' => 'App\Http\Middleware\CORS',
    ];

Then you can use it in your routes

Route::get('example', array('middleware' => 'cors', 'uses' => 'ExampleController@dummy'));

If you have defined a method inside your class as static, this is actually possible.

    class myClass
    {
    public:
        static void saySomething()
        {
            std::cout << "This is a static method!" << std::endl;
        }
    }; 

And from main, you declare a pointer and try to invoke the static method.

    myClass * pmyClass;
    pmyClass->saySomething();

/*    
Output:
This is a static method!
*/

This works fine because static methods do not belong to a specific instance of the class and they are not allocated as a part of any instance of the class.

Read more on static methods here: http://en.wikipedia.org/wiki/Static_method#Static_methods

You are getting a keySet iterator on the HashMap and expecting to iterate over entries.

Correct code:

    HashMap hm = new HashMap();

    hm.put(0, "zero");
    hm.put(1, "one");

    //Here we get the keyset iterator not the Entry iterator
    Iterator iter = (Iterator) hm.keySet().iterator();

    while(iter.hasNext()) {

        //iterator's next() return an Integer that is the key
        Integer key = (Integer) iter.next();
        //already have the key, now get the value using get() method
        System.out.println(key + " - " + hm.get(key));

    }

Iterating over a HashMap using EntrySet:

     HashMap hm = new HashMap();
     hm.put(0, "zero");
     hm.put(1, "one");
     //Here we get the iterator on the entrySet
     Iterator iter = (Iterator) hm.entrySet().iterator();


     //Traversing using iterator on entry set  
     while (iter.hasNext()) {  
         Entry<Integer,String> entry = (Entry<Integer,String>) iter.next();  
         System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());  
     }  

     System.out.println();


    //Iterating using for-each construct on Entry Set
    Set<Entry<Integer, String>> entrySet = hm.entrySet();
    for (Entry<Integer, String> entry : entrySet) {  
        System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());  
    }           

Look at the section -Traversing Through a HashMap in the below link. java-collection-internal-hashmap and Traversing through HashMap

Shouldn't the @Html.EditorFor() make use of the Attributes you put in your model?

I don't think it is very important to find the location of Svcutil.exe. You can use Visual Studio Command prompt to execute directly without its absolute path,

Syntax:
svcutil.exe /language:[vb|cs] /out:[YourClassName].[cs|vb] /config:[YourAppConfigFile.config] [YourServiceAddress]

example:
svcutil.exe /language:cs /out:MyClientClass.cs /config:app.config http://localhost:8370/MyService/

Some people say "always use IList<T> instead of List<T>".
They want you to change your method signatures from void Foo(List<T> input) to void Foo(IList<T> input).

These people are wrong.

It's more nuanced than that. If you are returning an IList<T> as part of the public interface to your library, you leave yourself interesting options to perhaps make a custom list in the future. You may not ever need that option, but it's an argument. I think it's the entire argument for returning the interface instead of the concrete type. It's worth mentioning, but in this case it has a serious flaw.

As a minor counterargument, you may find every single caller needs a List<T> anyway, and the calling code is littered with .ToList()

But far more importantly, if you are accepting an IList as a parameter you'd better be careful, because IList<T> and List<T> do not behave the same way. Despite the similarity in name, and despite sharing an interface they do not expose the same contract.

Suppose you have this method:

public Foo(List<int> a)
{
    a.Add(someNumber);
}

A helpful colleague "refactors" the method to accept IList<int>.

Your code is now broken, because int[] implements IList<int>, but is of fixed size. The contract for ICollection<T> (the base of IList<T>) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List<T> does not.

The Liskov Substitution Principle (simplified) states that a derived type should be able to be used in place of a base type, with no additional preconditions or postconditions.

This feels like it breaks the Liskov substitution principle.

 int[] array = new[] {1, 2, 3};
 IList<int> ilist = array;

 ilist.Add(4); // throws System.NotSupportedException
 ilist.Insert(0, 0); // throws System.NotSupportedException
 ilist.Remove(3); // throws System.NotSupportedException
 ilist.RemoveAt(0); // throws System.NotSupportedException

But it doesn't. The answer to this is that the example used IList<T>/ICollection<T> wrong. If you use an ICollection<T> you need to check the IsReadOnly flag.

if (!ilist.IsReadOnly)
{
   ilist.Add(4);
   ilist.Insert(0, 0); 
   ilist.Remove(3);
   ilist.RemoveAt(0);
}
else
{
   // what were you planning to do if you were given a read only list anyway?
}

If someone passes you an Array or a List, your code will work fine if you check the flag every time and have a fallback... But really; who does that? Don't you know in advance if your method needs a list that can take additional members; don't you specify that in the method signature? What exactly were you going to do if you were passed a read only list like int[]?

You can substitute a List<T> into code that uses IList<T>/ICollection<T> correctly. You cannot guarantee that you can substitute an IList<T>/ICollection<T> into code that uses List<T>.

There's an appeal to the Single Responsibility Principle / Interface Segregation Principle in a lot of the arguments to use abstractions instead of concrete types - depend on the narrowest possible interface. In most cases, if you are using a List<T> and you think you could use a narrower interface instead - why not IEnumerable<T>? This is often a better fit if you don't need to add items. If you need to add to the collection, use the concrete type, List<T>.

For me IList<T> (and ICollection<T>) is the worst part of the .NET framework. IsReadOnly violates the principle of least surprise. A class, such as Array, which never allows adding, inserting or removing items should not implement an interface with Add, Insert and Remove methods. (see also https://softwareengineering.stackexchange.com/questions/306105/implementing-an-interface-when-you-dont-need-one-of-the-properties)

Is IList<T> a good fit for your organisation? If a colleague asks you to change a method signature to use IList<T> instead of List<T>, ask them how they'd add an element to an IList<T>. If they don't know about IsReadOnly (and most people don't), then don't use IList<T>. Ever.

Note that the IsReadOnly flag comes from ICollection<T>, and indicates whether items can be added or removed from the collection; but just to really confuse things, it does not indicate whether they can be replaced, which in the case of Arrays (which return IsReadOnlys == true) can be.

For more on IsReadOnly, see msdn definition of ICollection<T>.IsReadOnly

A slightly modified binary search on the array would work.

If you look at the code for the component you can see that it uses the className prop passed to it to combine with the row class to get the resulting set of classes (<Row className="aaa bbb"... works).Also, if you provide the id prop like <Row id="444" ... it will actually set the id attribute for the element.

Depending on your context; this will allow you to update state given the mouseEnter function. Either way, by setting a state value to either true:false you can update that state value given any function by setting it to the opposing value with !this.state.variable

state = {
  hover: false
}

onMouseEnter = () => {
  this.setState({
    hover: !this.state.hover
  });
};

I believe those who study typography would tell you that 66 characters per a line is supposed to be the most readable width for length. Even so, if you need to debug a machine remotely over an ssh session, most terminals default to 80 characters, 79 just fits, trying to work with anything wider becomes a real pain in such a case. You would also be suprised by the number of developers using vim + screen as a day to day environment.

No, the Compare function will return either 1, 0, or -1. 0 when the two values are equal, -1 and 1 mean less than and greater than, I believe in that order, but I often mix them up.

Another way to do this is to define the functions in a groovy class and parse and add the file to the classpath at runtime:

File sourceFile = new File("path_to_file.groovy");
Class groovyClass = new GroovyClassLoader(getClass().getClassLoader()).parseClass(sourceFile);
GroovyObject myObject = (GroovyObject) groovyClass.newInstance();

I had the same problem after transferring all my applications from my old Mac to my new one.

I found the solution by running brew doctor :

Warning: Broken symlinks were found. Remove them with brew prune

After running brew prune, Homebrew is finally back on track :)

The other answers are very useful, thanks to the authors!

But I could not see how to customise the rectangle when highlighting an item upon selection rather than disabling the highlighting @alvins @bharat dojeha.

The following works for me to create a rounded list view item container with no outline and a lighter grey when selected of the same shape:

Your xml needs to contain a selector such as e.g. ( in res/drawable/customshape.xml):

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <stroke android:width="8dp" android:color="@android:color/transparent" />
        <padding android:left="14dp" android:top="14dp"
                android:right="14dp" android:bottom="14dp" />
        <corners android:radius="10dp" />
        <gradient 
             android:startColor="@android:color/background_light"
             android:endColor="@android:color/transparent" 
             android:angle="225"/> 
    </shape>
</item>
<item android:state_pressed="false">
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <stroke android:width="8dp" android:color="@android:color/transparent" />
        <padding android:left="14dp" android:top="14dp"
                android:right="14dp" android:bottom="14dp" />
        <corners android:radius="10dp" />
        <gradient 
             android:startColor="@android:color/darker_gray"
             android:endColor="@android:color/transparent" 
             android:angle="225"/> 
    </shape>        
</item>

Then you need to implement a list adapter and override the getView method to set the custom selector as background

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        //snip
        convertView.setBackgroundResource(R.drawable.customshape);
        //snip
    }

and need to also 'hide' the default selector rectangle e.g in onCreate (I also hide my thin grey divider line between the items):

listView.setSelector(android.R.color.transparent);
listview.setDivider(null);

This approach solves a general solution for drawables, not just ListViewItem with various selection states.

Try doing this :

awk '{print substr($0, 1, length($0)-1)}' file.txt

This is more generic than just removing the final comma but any last character

If you'd want to only remove the last comma with awk :

awk '{gsub(/,$/,""); print}' file.txt

You can also use RequestDispacher and pass on the data along with the jsp page you want.

request.setAttribute("MyData", data);
RequestDispatcher rd = request.getRequestDispatcher("page.jsp");
rd.forward(request, response);

I'm guessing the question you really care about here is:

Is there a way to force Python to release all the memory that was used (if you know you won't be using that much memory again)?

No, there is not. But there is an easy workaround: child processes.

If you need 500MB of temporary storage for 5 minutes, but after that you need to run for another 2 hours and won't touch that much memory ever again, spawn a child process to do the memory-intensive work. When the child process goes away, the memory gets released.

This isn't completely trivial and free, but it's pretty easy and cheap, which is usually good enough for the trade to be worthwhile.

First, the easiest way to create a child process is with concurrent.futures (or, for 3.1 and earlier, the futures backport on PyPI):

with concurrent.futures.ProcessPoolExecutor(max_workers=1) as executor:
    result = executor.submit(func, *args, **kwargs).result()

If you need a little more control, use the multiprocessing module.

The costs are:

• Process startup is kind of slow on some platforms, notably Windows. We're talking milliseconds here, not minutes, and if you're spinning up one child to do 300 seconds' worth of work, you won't even notice it. But it's not free.
• If the large amount of temporary memory you use really is large, doing this can cause your main program to get swapped out. Of course you're saving time in the long run, because that if that memory hung around forever it would have to lead to swapping at some point. But this can turn gradual slowness into very noticeable all-at-once (and early) delays in some use cases.
• Sending large amounts of data between processes can be slow. Again, if you're talking about sending over 2K of arguments and getting back 64K of results, you won't even notice it, but if you're sending and receiving large amounts of data, you'll want to use some other mechanism (a file, mmapped or otherwise; the shared-memory APIs in multiprocessing; etc.).
• Sending large amounts of data between processes means the data have to be pickleable (or, if you stick them in a file or shared memory, struct-able or ideally ctypes-able).

 $('#some_select_box').click(function() {
     $(this).find('option:selected').remove();
 });

Using the find method.

I m using Cordova version 7.0.1 and Cordova android version is 6.2.3. I was facing the issue while performing android build. I m using only Cordova CLI and not using android studio at all.

The quick workaround for this issue before its official fixed in Cordova is as follows:

1. Look for check_reqs.js file under platforms\android\cordova\lib folder
2. Edit the else part of androidStudioPath variable null check in get_gradle_wrapper function as below:

Existing code:

else { //OK, let's try to check for Gradle! return forgivingWhichSync('gradle'); }

Modified code:

else { //OK, let's try to check for Gradle! var sdkDir = process.env['ANDROID_HOME']; return path.join(sdkDir, 'tools', 'templates', 'gradle', 'wrapper', 'gradlew'); }

NOTE: This change needs to be done everytime when the android platform is removed and re-added

UPDATE: In my case, I already had gradle wrapper inside my android SDK and I dint find necessity to install gradle explicitly. Hence, I made this workaround to minimize my impact and effort

I don't recall where I picked this up, but have been using it successfully for ages.

  =hide-text()
    font: 0/0 a
    text-shadow: none
    color: transparent

My mixin is in sass however you can use it any way you see fit. For good measure I generally keep a .hidden class somewhere in my project to attach to elements to avoid duplication.

In my experience, the most friendly way of dealing with this is to have a function that converts a string into a table of values.

There are many splitter functions available on the web, you'll easily find one for whatever if your flavour of SQL.

You can then do...

SELECT * FROM table WHERE id IN (SELECT id FROM split(@list_of_ids))

Or

SELECT * FROM table INNER JOIN (SELECT id FROM split(@list_of_ids)) AS list ON list.id = table.id

(Or similar)

I wrote a simple ini config library in golang.

https://github.com/c4pt0r/cfg

goroutine-safe, easy to use

package cfg
import (
    "testing"
)

func TestCfg(t *testing.T) {
    c := NewCfg("test.ini")
    if err := c.Load() ; err != nil {
        t.Error(err)
    }
    c.WriteInt("hello", 42)
    c.WriteString("hello1", "World")

    v, err := c.ReadInt("hello", 0)
    if err != nil || v != 42 {
        t.Error(err)
    }

    v1, err := c.ReadString("hello1", "")
    if err != nil || v1 != "World" {
        t.Error(err)
    }

    if err := c.Save(); err != nil {
        t.Error(err)
    }
}

===================Update=======================

Recently I need an INI parser with section support, and I write a simple package:

github.com/c4pt0r/cfg

u can parse INI like using "flag" package:

package main

import (
    "log"
    "github.com/c4pt0r/ini"
)

var conf = ini.NewConf("test.ini")

var (
    v1 = conf.String("section1", "field1", "v1")
    v2 = conf.Int("section1", "field2", 0)
)

func main() {
    conf.Parse()

    log.Println(*v1, *v2)
}

I read all the clunky solutions on the net about how to mask passwords in a batch file, the ones from using a hide.com solution and even the ones that make the text and the background the same color. The hide.com solution works decent, it isn't very secure, and it doesn't work in 64-bit Windows. So anyway, using 100% Microsoft utilities, there is a way!

First, let me explain my use. I have about 20 workstations that auto logon to Windows. They have one shortcut on their desktop - to a clinical application. The machines are locked down, they can't right click, they can't do anything but access the one shortcut on their desktop. Sometimes it is necessary for a technician to kick up some debug applications, browse windows explorer and look at log files without logging the autolog user account off.

So here is what I have done.

Do it however you wish, but I put my two batch files on a network share that the locked down computer has access to.

My solution utilizes 1 main component of Windows - runas. Put a shortcut on the clients to the runas.bat you are about to create. FYI, on my clients I renamed the shortcut for better viewing purposes and changed the icon.

You will need to create two batch files.

I named the batch files runas.bat and Debug Support.bat

runas.bat contains the following code:

You can add as many if "%un%" and if not "%un%" for all the users you want to give access to. The @ping is my coonass way of making a seconds timer.

So that takes care of the first batch file - pretty simple eh?

Here is the code for Debug Support.bat:

cls
@echo off
TITLE SUPPORT UTILITIES
goto menu

:menu
cls
@echo %username%
echo.
echo           .....................................
echo            ~Written by Cajun Wonder 4/1/2010~
echo           .....................................
echo.
echo What do you want to do? 
echo.
echo [1]  Launch notepad
echo.

:choice
set /P C=[Option]? 
if "%C%"=="1" goto notepad
goto choice

:notepad
echo.
@echo starting notepad....
@ping -n 3 127.0.0.1 > NUL
start notepad
cls
goto menu

I'm not a coder and really just started getting into batch scripting about a year ago, and this round about way that I discovered of masking a password in a batch file is pretty awesome!

I hope to hear that someone other than me is able to get some use out of it!

I recommend checking out mongosniff. This can tool can do everything you want and more. Especially it can help diagnose issues with larger scale mongo systems and how queries are being routed and where they are coming from since it works by listening to your network interface for all mongo related communications.

http://docs.mongodb.org/v2.2/reference/mongosniff/

Stub

I believe the biggest distinction is that a stub you have already written with predetermined behavior. So you would have a class that implements the dependency (abstract class or interface most likely) you are faking for testing purposes and the methods would just be stubbed out with set responses. They would not do anything fancy and you would have already written the stubbed code for it outside of your test.

Mock

A mock is something that as part of your test you have to setup with your expectations. A mock is not setup in a predetermined way so you have code that does it in your test. Mocks in a way are determined at runtime since the code that sets the expectations has to run before they do anything.

Difference between Mocks and Stubs

Tests written with mocks usually follow an initialize -> set expectations -> exercise -> verify pattern to testing. While the pre-written stub would follow an initialize -> exercise -> verify.

Similarity between Mocks and Stubs

The purpose of both is to eliminate testing all the dependencies of a class or function so your tests are more focused and simpler in what they are trying to prove.

Some manufacturers lock out the bios menu so that you can't turn VT on if this is the case there is another way to turn it on using a program called CPUID. Check out this video if this is your problem: https://www.youtube.com/watch?v=YPjTFam30kc

Well for me the issue was even more annoying, I was using a service within a service and forgot to add it as dependency in the appModule! Hope this helps someone save several hours breaking the app down only to build it back up again

I had a similar problem. NuGet showed the package successfully installed, but the reference was not added to my project.

Running <PM> Install-Package Microsoft.Web.InfraStructure also didn't help as the package manager kept saying it's already installed

I finally added it manually by editing the csproj file and adding these lines:

 <Reference Include="Microsoft.Web.Infrastructure">
  <HintPath>..\packages\Microsoft.Web.Infrastructure.1.0.0.0\lib\net40\Microsoft.Web.Infrastructure.dll</HintPath>
  <Private>True</Private>
</Reference>

That solved the problem.

read() and write() are more generic, they work with any file descriptor. However, they won't work on Windows.

You can pass additional options to send() and recv(), so you may have to used them in some cases.

Try + (instancetype)appearance of UITableView:

Objective-C:

[[UITableView appearance] setSeparatorColor:[UIColor blackColor]]; // set your desired colour in place of "[UIColor blackColor]"

Swift 3.0:

UITableView.appearance().separatorColor = UIColor.black // set your desired colour in place of "UIColor.black"

Note: Change will reflect to all tables used in application.

In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:

httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

Usage

git clone <repository>

Clone the repository located at the <repository> onto the local machine. The original repository can be located on the local filesystem or on a remote machine accessible via HTTP or SSH.

git clone <repo> <directory>

Clone the repository located at <repository> into the folder called <directory> on the local machine.

    }

    try {
        Class.forName("org.postgresql.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    try {
        this.conn = DriverManager.getConnection(this.host + ':' + this.port + '/' + this.dbName, this.user, this.pass);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    return true;
}

receiving class:

_store.execute();
boolean result =_store.get();

Hoping it will help.

Unfortunately, if you're trying to debug something at the very start of a Windows Service operation, "attaching" to the running process won't work. I tried using Debugger.Break() within the OnStart procecdure, but with a 64-bit, Visual Studio 2010 compiled application, the break command just throws an error like this:

System error 1067 has occurred.

At that point, you need to set up an "Image File Execution" option in your registry for your executable. It takes five minutes to set up, and it works very well. Here's a Microsoft article where the details are:

How to: Launch the Debugger Automatically

You can also limit the filter to only part of the ip address.

E.G. To filter 123.*.*.* you can use ip.addr == 123.0.0.0/8. Similar effects can be achieved with /16 and /24.

See WireShark man pages (filters) and look for Classless InterDomain Routing (CIDR) notation.

... the number after the slash represents the number of bits used to represent the network.

Why did not anyone mention setOnTouchListener? Using setOnTouchListener is easy and all right, and just return true if the listener has consumed the event, false otherwise.

Click the items in the list view. Add a button that will edit the selected items. Add the code

try
{              
    LSTDEDUCTION.SelectedItems[0].SubItems[1].Text = txtcarName.Text;
    LSTDEDUCTION.SelectedItems[0].SubItems[0].Text = txtcarBrand.Text;
    LSTDEDUCTION.SelectedItems[0].SubItems[2].Text = txtCarName.Text;
}
catch{}

Presuming that you are running the 64bit Ubuntu, the fix suggested for "Issue 82711" should solve your problem.

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6

Update: For Ubuntu 15.10 & 16.04 sudo apt-get install lib32z1 lib32ncurses5 lib32stdc++6

Try x-1 in (i for i in range(x)) for large x values, which uses a generator comprehension to avoid invoking the range.__contains__ optimisation.

If you are like me and you are using one of the PHP Docker images as your base, you need to add the gd extension using different instructions then what's discussed above.

For the php:7.4.1-apache image you need to add in your Dockerfile:

RUN apt-get update && \
    apt-get install -y zlib1g-dev libpng-dev libjpeg-dev

RUN docker-php-ext-configure gd --with-jpeg && \
    docker-php-ext-install gd

These dev packages are needed for compilation of the GD php extension. For me this resulted in activation of GD with PNG and JPEG support in PHP.

A couple of scenarios might help illustrate the purpose of access and refresh tokens and the engineering trade-offs in designing an oauth2 (or any other auth) system:

Web app scenario

In the web app scenario you have a couple of options:

1. if you have your own session management, store both the access_token and refresh_token against your session id in session state on your session state service. When a page is requested by the user that requires you to access the resource use the access_token and if the access_token has expired use the refresh_token to get the new one.

Let's imagine that someone manages to hijack your session. The only thing that is possible is to request your pages.

2. if you don't have session management, put the access_token in a cookie and use that as a session. Then, whenever the user requests pages from your web server send up the access_token. Your app server could refresh the access_token if need be.

Comparing 1 and 2:

In 1, access_token and refresh_token only travel over the wire on the way between the authorzation server (google in your case) and your app server. This would be done on a secure channel. A hacker could hijack the session but they would only be able to interact with your web app. In 2, the hacker could take the access_token away and form their own requests to the resources that the user has granted access to. Even if the hacker gets a hold of the access_token they will only have a short window in which they can access the resources.

Either way the refresh_token and clientid/secret are only known to the server making it impossible from the web browser to obtain long term access.

Let's imagine you are implementing oauth2 and set a long timeout on the access token:

In 1) There's not much difference here between a short and long access token since it's hidden in the app server. In 2) someone could get the access_token in the browser and then use it to directly access the user's resources for a long time.

Mobile scenario

On the mobile, there are a couple of scenarios that I know of:

1. Store clientid/secret on the device and have the device orchestrate obtaining access to the user's resources.

2. Use a backend app server to hold the clientid/secret and have it do the orchestration. Use the access_token as a kind of session key and pass it between the client and the app server.

Comparing 1 and 2

In 1) Once you have clientid/secret on the device they aren't secret any more. Anyone can decompile and then start acting as though they are you, with the permission of the user of course. The access_token and refresh_token are also in memory and could be accessed on a compromised device which means someone could act as your app without the user giving their credentials. In this scenario the length of the access_token makes no difference to the hackability since refresh_token is in the same place as access_token. In 2) the clientid/secret nor the refresh token are compromised. Here the length of the access_token expiry determines how long a hacker could access the users resources, should they get hold of it.

Expiry lengths

Here it depends upon what you're securing with your auth system as to how long your access_token expiry should be. If it's something particularly valuable to the user it should be short. Something less valuable, it can be longer.

Some people like google don't expire the refresh_token. Some like stackflow do. The decision on the expiry is a trade-off between user ease and security. The length of the refresh token is related to the user return length, i.e. set the refresh to how often the user returns to your app. If the refresh token doesn't expire the only way they are revoked is with an explicit revoke. Normally, a log on wouldn't revoke.

Hope that rather length post is useful.

The above answer doesn't work. You have to set DeliveryMethod = SmtpDeliveryMethod.Network or it will come back with a "client was not authenticated" error. Also it's always a good idea to put a timeout.

Revised code:

using System.Net.Mail;
using System.Net;

var fromAddress = new MailAddress("[email protected]", "From Name");
var toAddress = new MailAddress("[email protected]", "To Name");
const string fromPassword = "password";
const string subject = "test";
const string body = "Hey now!!";

var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
    Timeout = 20000
};
using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

Current route properties are present in this.$route, this.$router is the instance of router object which gives the configuration of the router. You can get the current route query using this.$route.query

setInterval(function() {
    updatechat();
}, 2000);

function updatechat() {
    alert('hello world');
}

<script language="JavaScript" type="text/javascript">

{
    var fileinput = document.getElementById("browse");
    fileinput.click();
}
function Handlechange()
{
var fileinput = document.getElementById("browse");
var textinput = document.getElementById("filename");
textinput.value = fileinput.value;
}
</script>

<input type="file" id="browse" name="fileupload" style="display: none" onChange="Handlechange();"/>
<input type="text" id="filename" readonly="true"/>
<input type="button" value="Click to select file" id="fakeBrowse" onclick="HandleBrowseClick();"/>

You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .

public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
    Iterator<String> keys = json.keys();
    while(keys.hasNext()){
        String key = keys.next();
        String val = null;
        try{
             JSONObject value = json.getJSONObject(key);
             parse(value,out);
        }catch(Exception e){
            val = json.getString(key);
        }

        if(val != null){
            out.put(key,val);
        }
    }
    return out;
}

 public static void main(String[] args) throws JSONException {

    String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";

    JSONObject object = new JSONObject(json);

    JSONObject info = object.getJSONObject("ipinfo");

    Map<String,String> out = new HashMap<String, String>();

    parse(info,out);

    String latitude = out.get("latitude");
    String longitude = out.get("longitude");
    String city = out.get("city");
    String state = out.get("state");
    String country = out.get("country");
    String postal = out.get("postal_code");

    System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);

    System.out.println("ALL VALUE " + out);

}

Output:

    Latitude : 30.1 LongiTude : -81.714 City : fleming island State : florida Country : united states postal 32003
ALL VALUE {region=southeast, ip_type=Mapped, state_code=fl, state=florida, country_code=us, city=fleming island, country=united states, time_zone=-5, ip_address=131.208.128.15, postal_code=32003, continent=north america, longitude=-81.714, latitude=30.1}
