It's a good idea to apply a recursive definition, as in Vadim Smolyakov's answer, combined with a DP (dynamic programming), but for the latter you may apply the lru_cache decorator from module functools:

import functools

@functools.lru_cache(maxsize = None)
def binom(n,k):
    if k == 0: return 1
    if n == k: return 1
    return binom(n-1,k-1)+binom(n-1,k)

I am assuming that you are making a quiz kind of application. For this kind of application I have written a function which is as follows:

def shuffle(q):
"""
The input of the function will 
be the dictionary of the question
and answers. The output will
be a random question with answer
"""
selected_keys = []
i = 0
while i < len(q):
    current_selection = random.choice(q.keys())
    if current_selection not in selected_keys:
        selected_keys.append(current_selection)
        i = i+1
        print(current_selection+'? '+str(q[current_selection]))

If I will give the input of questions = {'VENEZUELA':'CARACAS', 'CANADA':'TORONTO'} and call the function shuffle(questions) Then the output will be as follows:

VENEZUELA? CARACAS
CANADA? TORONTO

You can extend this further more by shuffling the options also

SEND TO EMAIL CLIENTS ONLY - WITH MULTIPLE ATTACHMENTS

There are many solutions but all work partially.

mailto properly filters email apps but it has the inability of not sending streams/files.

message/rfc822 opens up hell of apps along with email clients

so, the solution for this is to use both.

1. First resolve intent activities using mailto intent
2. Then set the data to each activity resolved to send the required data

private void share()
{
     Intent queryIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"));
     Intent dataIntent  = getDataIntent();

     Intent targetIntent = getSelectiveIntentChooser(context, queryIntent, dataIntent);
     startActivityForResult(targetIntent);
}

Build the required data intent which is filled with required data to share

private Intent getDataIntent()
{
        Intent dataIntent = buildIntent(Intent.ACTION_SEND, null, "message/rfc822", null);

        // Set subject
        dataIntent.putExtra(Intent.EXTRA_SUBJECT, title);

        //Set receipient list.
        dataIntent.putExtra(Intent.EXTRA_EMAIL, toRecipients);
        dataIntent.putExtra(Intent.EXTRA_CC, ccRecipients);
        dataIntent.putExtra(Intent.EXTRA_BCC, bccRecipients);
        if (hasAttachments())
        {
            ArrayList<Uri> uris = getAttachmentUriList();

            if (uris.size() > 1)
            {
                intent.setAction(Intent.ACTION_SEND_MULTIPLE);
                dataIntent.putExtra(Intent.EXTRA_STREAM, uris);
            }
            else
            {
                dataIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris.get(0));
            }
        }

        return dataIntent;
}

protected ArrayList<Uri> getAttachmentUriList()
{
        ArrayList<Uri> uris = new ArrayList();
        for (AttachmentInfo eachAttachment : attachments)
        {
            uris.add(eachAttachment.uri);
        }

        return uris;
}

Utitlity class for filtering required intents based on query intent

// Placed in IntentUtil.java
public static Intent getSelectiveIntentChooser(Context context, Intent queryIntent, Intent dataIntent)
{
        List<ResolveInfo> appList = context.getPackageManager().queryIntentActivities(queryIntent, PackageManager.MATCH_DEFAULT_ONLY);

        Intent finalIntent = null;

        if (!appList.isEmpty())
        {
            List<android.content.Intent> targetedIntents = new ArrayList<android.content.Intent>();

            for (ResolveInfo resolveInfo : appList)
            {
                String packageName = resolveInfo.activityInfo != null ? resolveInfo.activityInfo.packageName : null;

                Intent allowedIntent = new Intent(dataIntent);
                allowedIntent.setComponent(new ComponentName(packageName, resolveInfo.activityInfo.name));
                allowedIntent.setPackage(packageName);

                targetedIntents.add(allowedIntent);
            }

            if (!targetedIntents.isEmpty())
            {
                //Share Intent
                Intent startIntent = targetedIntents.remove(0);

                Intent chooserIntent = android.content.Intent.createChooser(startIntent, "");
                chooserIntent.putExtra(android.content.Intent.EXTRA_INITIAL_INTENTS, targetedIntents.toArray(new Parcelable[]{}));
                chooserIntent.addFlags(android.content.Intent.FLAG_GRANT_READ_URI_PERMISSION);

                finalIntent = chooserIntent;
            }

        }

        if (finalIntent == null) //As a fallback, we are using the sent data intent
        {
            finalIntent = dataIntent;
        }

        return finalIntent;
}

You are dividing by rr which may be 0.0. Check if rr is zero and do something reasonable other than using it in the denominator.

Swift 3 syntax:

tableView.tableFooterView = UIView(frame: .zero)

Swift syntax: < 2.0

tableView.tableFooterView = UIView(frame: CGRect.zeroRect)

Swift 2.0 syntax:

The following function determine all possibilities and return the values in a comma separated format (ip, ip, etc.).

It has also an optional validation function as (first parameter that disabled by default) to validate the IP address against (private range and reserved range).

        }
      }
      else{
        $ip[] = $_SERVER[$keyword];
      }
    }
  }

  $ip = ( empty($ip) ? 'Unknown' : implode(", ", $ip) );
  return $ip;
}

  if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE)) {
    return true;
  }
  else {
    return false;

}

Sorry for digging out an old thread, but I think sunetos' answer isn't correct (or isn't the full answer). I've done some experiments (using ProcessStartInfo in c#) and it seems that the 'arguments' string for a commandline command is limited to 2048 characters in XP and 32768 characters in Win7. I'm not sure what the 8191 limit refers to, but I haven't found any evidence of it yet.

If all above stuffs not works. try this. If you are using IntelliJ. Check below setting:

May be ~/.m2/settings.xml is restricting to connect to internet.

Update:

These articles in my blog describe the differences between the methods in more detail:

• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: SQL Server
• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: PostgreSQL
• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: Oracle
• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: MySQL

There are three ways to do such a query:

• LEFT JOIN / IS NULL:

  SELECT  *
  FROM    common
  LEFT JOIN
          table1 t1
  ON      t1.common_id = common.common_id
  WHERE   t1.common_id IS NULL
  

• NOT EXISTS:

  SELECT  *
  FROM    common
  WHERE   NOT EXISTS
          (
          SELECT  NULL
          FROM    table1 t1
          WHERE   t1.common_id = common.common_id
          )
  

• NOT IN:

  SELECT  *
  FROM    common
  WHERE   common_id NOT IN
          (
          SELECT  common_id
          FROM    table1 t1
          )
  

When table1.common_id is not nullable, all these queries are semantically the same.

When it is nullable, NOT IN is different, since IN (and, therefore, NOT IN) return NULL when a value does not match anything in a list containing a NULL.

This may be confusing but may become more obvious if we recall the alternate syntax for this:

common_id = ANY
(
SELECT  common_id
FROM    table1 t1
)

The result of this condition is a boolean product of all comparisons within the list. Of course, a single NULL value yields the NULL result which renders the whole result NULL too.

We never cannot say definitely that common_id is not equal to anything from this list, since at least one of the values is NULL.

Suppose we have these data:

common

--
1
3

table1

--
NULL
1
2

LEFT JOIN / IS NULL and NOT EXISTS will return 3, NOT IN will return nothing (since it will always evaluate to either FALSE or NULL).

In MySQL, in case on non-nullable column, LEFT JOIN / IS NULL and NOT IN are a little bit (several percent) more efficient than NOT EXISTS. If the column is nullable, NOT EXISTS is the most efficient (again, not much).

In Oracle, all three queries yield same plans (an ANTI JOIN).

In SQL Server, NOT IN / NOT EXISTS are more efficient, since LEFT JOIN / IS NULL cannot be optimized to an ANTI JOIN by its optimizer.

In PostgreSQL, LEFT JOIN / IS NULL and NOT EXISTS are more efficient than NOT IN, sine they are optimized to an Anti Join, while NOT IN uses hashed subplan (or even a plain subplan if the subquery is too large to hash)

sudo apt-get -y --reinstall install phpmyadmin;
sudo service apache2 restart;

Hope this helps.

Another pure Bash solution:

while IFS=':' read a b ; do
  echo "$a"
done < "$infile" > "$outfile"

$> export RAILS_ENV=production

The main difference between a session and a cookie is that session data is stored on the server, whereas cookies store data in the visitor’s browser.

Sessions are more secure than cookies as it is stored in server. Cookie can be turned off from browser.

Data stored in cookie can be stored for months or years, depending on the life span of the cookie. But the data in the session is lost when the web browser is closed.

I have a couple corrections/additions to Born2Smile's very useful answer:

1. Empty bins caused the box for the adjacent bin to incorrectly extend into its space; avoid this using set boxwidth binwidth
2. In Born2Smile's version, bins are rendered as centered on their lower bound. Strictly they ought to extend from the lower bound to the upper bound. This can be corrected by modifying the bin function: bin(x,width)=width*floor(x/width) + width/2.0

In Angular2 RC2 you can use this simple implementation

<a [routerLink]="['/dashboard']" routerLinkActive="active">Dashboard</a>

this will add class active to the element with matched url, read more about it here

Just to be really clear, this has nothing to do with enumerate and everything to do with list comprehension syntax.

This list comprehension returns a list of tuples:

[(i,j) for i in range(3) for j in 'abc']

this a list of dicts:

[{i:j} for i in range(3) for j in 'abc']

a list of lists:

[[i,j] for i in range(3) for j in 'abc']

a syntax error:

[i,j for i in range(3) for j in 'abc']

Which is inconsistent (IMHO) and confusing with dictionary comprehensions syntax:

>>> {i:j for i,j in enumerate('abcdef')}
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f'}

And a set of tuples:

>>> {(i,j) for i,j in enumerate('abcdef')}
set([(0, 'a'), (4, 'e'), (1, 'b'), (2, 'c'), (5, 'f'), (3, 'd')])

As Óscar López stated, you can just pass the enumerate tuple directly:

>>> [t for t in enumerate('abcdef') ] 
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f')]

Use Notification Center in the viewDidLoad: method of your ViewController to call a method and from there do what you were supposed to do in your viewWillAppear: method. Calling viewWillAppear: directly is not a good option.

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSLog(@"view did load");

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationIsActive:) 
        name:UIApplicationDidBecomeActiveNotification 
        object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationEnteredForeground:) 
        name:UIApplicationWillEnterForegroundNotification
        object:nil];
}

- (void)applicationIsActive:(NSNotification *)notification {
    NSLog(@"Application Did Become Active");
}

- (void)applicationEnteredForeground:(NSNotification *)notification {
    NSLog(@"Application Entered Foreground");
}

Here is how I would do it using vanilla JS

<form id="myform" method="POST" action="xxx">
    <!-- your stuff here -->
    <a href="javascript:void()" onclick="document.getElementById('myform').submit();>Ponies await!</a>
</form>

You can play with the return falses and href="#" vs void and whatever you need to but this method worked for me in Chrome 18, IE 9 and Firefox 14 and the rest depends on your javascript mostly.

The reason why this header shows is that: your request don't send to remote.

It usually caused by

1. Extension has blocks your request
2. Chrome use own cache to fetch your resource

Chrome cannot get your request headers from a request that haven't made.

A recent version of chrome has indicate these:

Only Provisional headers are avaliable because this request was not sent over the network and instead was served from a local cache, which doesn't store the original request headers.

Disable cache to see full request headers

DECLARE 
    @DateFrom DATETIME = GETDATE(),
    @DateTo DATETIME = DATEADD(HOUR, -1, GETDATE() + 2); -- Add 2 days and minus one hour


-- Dates spaced a day apart 

WITH MyDates (MyDate)
AS (
    SELECT @DateFrom
    UNION ALL
    SELECT DATEADD(DAY, 1, MyDate)
    FROM MyDates
    WHERE MyDate < @DateTo
   )

SELECT 
    MyDates.MyDate
    , CONVERT(DATE, MyDates.MyDate) AS [MyDate in DATE format]
FROM 
    MyDates;

Here is a similar example, but this time the dates are spaced one hour apart to further aid understanding of how the query works:

-- Alternative example with dates spaced an hour apart

WITH MyDates (MyDate)
AS (SELECT @DateFrom
    UNION ALL
    SELECT DATEADD(HOUR, 1, MyDate)
    FROM MyDates
    WHERE MyDate < @DateTo
   )

SELECT 
    MyDates.MyDate
FROM 
    MyDates;

As you can see, the query is fast, accurate and versatile.

I had a similar error type. First, I tried to add the meta tags in the code, but it didn't work.

I found out that on the nginx web server you may have a security setting that may block external code to run:

# Security directives
server_tokens off;
add_header X-Frame-Options SAMEORIGIN;
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'  https://ajax.googleapis.com  https://ssl.google-analytics.com https://assets.zendesk.com https://connect.facebook.net; img-src 'self' https://ssl.google-analytics.com https://s-static.ak.facebook.com https://assets.zendesk.com; style-src 'self' 'unsafe-inline' https://assets.zendesk.com; font-src 'self' https://fonts.gstatic.com  https://themes.googleusercontent.com; frame-src https://player.vimeo.com https://assets.zendesk.com https://www.facebook.com https://s-static.ak.facebook.com https://tautt.zendesk.com; object-src 'none'";

Check the Content-Security-Policy. You may need to add the source reference.

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

The most straight forward, and most efficient, would be to simply loop through the characters in the string:

int cnt = 0;
foreach (char c in test) {
  if (c == '&') cnt++;
}

You can use Linq extensions to make a simpler, and almost as efficient version. There is a bit more overhead, but it's still surprisingly close to the loop in performance:

int cnt = test.Count(c => c == '&');

Then there is the old Replace trick, however that is better suited for languages where looping is awkward (SQL) or slow (VBScript):

int cnt = test.Length - test.Replace("&", "").Length;

The OP has not defined the scope of testing, however, simple (gross) 'smoke testing' an install should be performed before any time is invested with functionality testing.

How to test if application is installed ('smoke-test')

Log into the mosquitto server's command line and type:

mosquitto

If mosquitto is installed the machine will return:

 mosquitto version 1.4.8 (build date Wed, date of installation) starting
 Using default config.
 Opening ipv4 listen socket on port 1883

Above solutions will work only if its a string. Input type date, gives you output in javascript date object in some cases like if you use angular or so. That's why some people are getting error like "TypeError: str.split is not a function". It's a date object, so you should use functions of Date object in javascript to manipulate it. Example here:

var date = $scope.dateObj ; 
//dateObj is data bind to the ng-modal of input type dat.
console.log(date.getFullYear()); //this will give you full year eg : 1990
console.log(date.getDate()); //gives you the date from 1 to 31
console.log(date.getMonth() + 1); //getMonth will give month from 0 to 11 

Check the following link for reference:

Try this -

<?php
date_default_timezone_set('Asia/Kolkata');

$timestamp = time();
$date_time = date("d-m-Y (D) H:i:s", $timestamp);
echo "Current date and local time on this server is $date_time";
?>

I totally agree with @jemmons:

But this should not be the default pattern you follow when dealing with blocks that call self! This should only be used to break what would otherwise be a retain cycle between self and the block. If you were to adopt this pattern everywhere, you'd run the risk of passing a block to something that got executed after self was deallocated.

//SUSPICIOUS EXAMPLE:
__weak MyObject *weakSelf = self;
[[SomeOtherObject alloc] initWithCompletion:^{
  //By the time this gets called, "weakSelf" might be nil because it's not  retained!
  [weakSelf doSomething];
}];

To overcome this problem one can define a strong reference over the weakSelf inside the block:

__weak MyObject *weakSelf = self;
[[SomeOtherObject alloc] initWithCompletion:^{
  MyObject *strongSelf = weakSelf;
  [strongSelf doSomething];
}];

Can be easily achieved with a ternary operator.

$is_negative = $profitloss < 0 ? true : false;

If you use JDK version from 9+, you should select

Then, select @argfile (Java 9+) as in the image below. Please try it. Good luck friends.

UPDATE table1 SET (col1, col2) = (col2, col3) FROM othertable WHERE othertable.col1 = 123;

Just for anyone else landing on this page from Google or elsewhere, this answer is probably the best answer out of all of them.

To summarize, simply hit:

CTRL + ,

And then start typing the file name.

if you want to change your icons to a Vector , create a new one. and then in your Activity.java :

Toolbar toolbar = findViewById(R.id.your_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.setNavigationIcon(R.drawable.your_icon);
mToolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.your_icon2));

To change Vector icon Color, go to your Vector XML file.. in this case it will be your_icon.xml, it will look like this :

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
    android:viewportHeight="24.0">
<path
    android:fillColor="@color/Your_Color"
    android:pathData="M15.41,7.41L14,6l-6,6 6,6 1.41,-1.41L10.83,12z"/>

Note that we used these attributes to set the Vector's color :

android:fillColor="@color/Your_Color"

Edit : You can't use a color from your colors.XML or somewhere else , the color must be decalred directly in the Vector's XML file.. so it will look like this :

If you're only interested in the keys, you can iterate through the keySet() of the map:

Map<String, Object> map = ...;

for (String key : map.keySet()) {
    // ...
}

If you only need the values, use values():

for (Object value : map.values()) {
    // ...
}

Finally, if you want both the key and value, use entrySet():

for (Map.Entry<String, Object> entry : map.entrySet()) {
    String key = entry.getKey();
    Object value = entry.getValue();
    // ...
}

One caveat: if you want to remove items mid-iteration, you'll need to do so via an Iterator (see karim79's answer). However, changing item values is OK (see Map.Entry).

In addition to Jesse Glick answer, if you want to pass string parameter then use:

build job: 'your-job-name', 
    parameters: [
        string(name: 'passed_build_number_param', value: String.valueOf(BUILD_NUMBER)),
        string(name: 'complex_param', value: 'prefix-' + String.valueOf(BUILD_NUMBER))
    ]

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

There are a few options...

1. Override the push method

Object.defineProperty(myArray, "push", {
  enumerable: false, // hide from for...in
  configurable: false, // prevent further meddling...
  writable: false, // see above ^
  value: function () {
    for (var i = 0, n = this.length, l = arguments.length; i < l; i++, n++) {          
      RaiseMyEvent(this, n, this[n] = arguments[i]); // assign/raise your event
    }
    return n;
  }
});

_{¹ Alternatively, if you'd like to target all arrays, you could override Array.prototype.push(). Use caution, though; other code in your environment may not like or expect that kind of modification. Still, if a catch-all sounds appealing, just replace myArray with Array.prototype.}

Now, that's just one method and there are lots of ways to change array content. We probably need something more comprehensive...

2. Create a custom observable array

function ObservableArray(items) {
  var _self = this,
    _array = [],
    _handlers = {
      itemadded: [],
      itemremoved: [],
      itemset: []
    };

  function defineIndexProperty(index) {
    if (!(index in _self)) {
      Object.defineProperty(_self, index, {

        get: function() {

        }
      });
    }
  }

      var h = _handlers[eventName];
      var ln = h.length;
      while (--ln >= 0) {
        if (h[ln] === handler) {

That gets us closer but it's still not bullet proof... which brings us to:

3. Proxies

A Proxy object offers another solution to the modern browser. It allows you to intercept method calls, accessors, etc. Most importantly, you can do this without even providing an explicit property name... which would allow you to test for an arbitrary, index-based access/assignment. You can even intercept property deletion. Proxies would effectively allow you to inspect a change before deciding to allow it... in addition to handling the change after the fact.

Here's a stripped down sample:

(function() {

  if (!("Proxy" in window)) {
    console.warn("Your browser doesn't support Proxies.");
    return;
  }

  // our backing array
  var array = ["a", "b", "c", "d"];

  // a proxy for our array
  var proxy = new Proxy(array, {
    apply: function(target, thisArg, argumentsList) {
      return thisArg[target].apply(this, argumentList);
    },
    deleteProperty: function(target, property) {
      console.log("Deleted %s", property);
      return true;
    },
    set: function(target, property, value, receiver) {      
      target[property] = value;
      console.log("Set %s to %o", property, value);
      return true;
    }
  });

  console.log("Set a specific index..");
  proxy[0] = "x";

  console.log("Add via push()...");
  proxy.push("z");

  console.log("Add/remove via splice()...");
  proxy.splice(1, 3, "y");

  console.log("Current state of array: %o", array);

})();

You don't need to do anything special, actually. You can mix JavaScript and PHP together to get variables from PHP straight into JavaScript.

var param1val = '<?php echo $_GET['param1'] ?>';

print("My type is %s" % type(someObject)) # the type in python

or...

print("My type is %s" % type(someObject).__name__) # the object's type (the class you defined)

For me setting alignItems to a parent did the trick, like:

var styles = StyleSheet.create({
  container: {
    alignItems: 'flex-end'
  }
});

Crazy idea...

You could play around with some pseudo elements, and create up/down arrows of css content hex codes. The only challange will be to precise the positioning of the arrow, but it may work:

input[type="number"] {_x000D_
    height: 100px;_x000D_
}_x000D_
_x000D_
.number-wrapper {_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.number-wrapper:hover:after {_x000D_
    content: "\25B2";_x000D_
    position: absolute;_x000D_
    color: blue;_x000D_
    left: 100%;_x000D_
    margin-left: -17px;_x000D_
    margin-top: 12%;_x000D_
    font-size: 11px;_x000D_
}_x000D_
_x000D_
.number-wrapper:hover:before {_x000D_
    content: "\25BC";_x000D_
    position: absolute;_x000D_
    color: blue;_x000D_
    left: 100%;_x000D_
    bottom: 0;_x000D_
    margin-left: -17px;_x000D_
    margin-bottom: -14%;_x000D_
    font-size: 11px;_x000D_
}

<span class='number-wrapper'>_x000D_
    <input type="number" />_x000D_
</span>

After looking on the accepted answer I realized that if know size of required vector then we have to use a loop to initialize every element

But I found new to do this using default_structure_element like following...

#include <bits/stdc++.h>
typedef long long ll;
using namespace std;

typedef struct subject {
  string name;
  int marks;
  int credits;
}subject;

int main(){
  subject default_subject;
  default_subject.name="NONE";
  default_subject.marks = 0;
  default_subject.credits = 0;

  vector <subject> sub(10,default_subject);         // default_subject to initialize

  //to check is it initialised
  for(ll i=0;i<sub.size();i++) {
    cout << sub[i].name << " " << sub[i].marks << " " << sub[i].credits << endl;
  } 
}

Then I think its good to way to initialize a vector of the struct, isn't it?

cout << fixed << setprecision(2) << total;

setprecision specifies the minimum precision. So

cout << setprecision (2) << 1.2; 

will print 1.2

fixed says that there will be a fixed number of decimal digits after the decimal point

cout << setprecision (2) << fixed << 1.2;

will print 1.20

You can install "Extended Read Permission" plug-in. Then in either "Global Settings" or in individual job configuration, you can give the user "Extended Read" permission.

If you search non-recursively you can use glop patterns to match the filenames.

grep "foo" *.{html,txt}

includes html and txt. It searches in the current directory only.

To search in the subdirectories:

   grep "foo" */*.{html,txt}

In the subsubdirectories:

   grep "foo" */*/*.{html,txt}

A simple trick is to define the $_SESSION array as a global variable. For that, edit the core.php file in the extension folder by adding this function :

public function getGlobals() {
    return array(
        'session'   => $_SESSION,
    ) ;
}

Then, you'll be able to acces any session variable as :

{{ session.username }}

if you want to access to

$_SESSION['username']

A void* can point to anything (it's a raw pointer without any type info).

You don't need to bind the submit event on the click of the submit button just bind the submit event and it will capture the submit event no mater how it gets triggered.

Think what you are wanting is to submit the sortable like you would via ajax. Try doing something like this:

var form = $('#event').submit(function () {
    $.each($('#attendance').sortable('toArray'),function(i, value){
        $("<input>").attr({
            'type':'hidden',
            'name':'attendace['+i+']'
        }).val(value).appendTo(form);
    });
});

Ruby exposes several different methods for handling equality:

a.equal?(b) # object identity - a and b refer to the same object

a.eql?(b) # object equivalence - a and b have the same value

a == b # object equivalence - a and b have the same value with type conversion.

My friend Brian wrote a comprehensive article on this. I think it is a great intro to how to use topics. https://www.brianstorti.com/vim-registers/

RowDefinition and ColumnDefinition are of type ContentElement, and Margin is strictly a FrameworkElement property. So to your question, "is it easily possible" the answer is a most definite no. And no, I have not seen any layout panels that demonstrate this kind of functionality.

You can add extra rows or columns as you suggested. But you can also set margins on a Grid element itself, or anything that would go inside a Grid, so that's your best workaround for now.

If you don't want to import calendar and apply .isleap method you can try this:

def isleapyear(year):
    if year % 4 == 0 and (year % 100 != 0 or year % 400 == 0):
        return True
    return False

Modules are fine for storing enums and some global variables, constants and shared functions. its very good thing and I often use it. Declared variables are visible acros entire project.

To completely remove the style attribute of the voltaic_holder span, do this:

$("#voltaic_holder").removeAttr("style");

To add an attribute, do this:

$("#voltaic_holder").attr("attribute you want to add", "value you want to assign to attribute");

To remove only the top style, do this:

$("#voltaic_holder").css("top", "");

The Correct Solution

scrollHeight

You should use document.getElementById(id).style.maxHeight = document.getElementById(id).scrollHeight+"px".

And in the CSS: transition: max-height 1s ease-in-out;

DO NOT USE the Atom platformio-atom-ide-terminal Plugin to do this. USE THE TERMINAL OF YOUR DISTRO DIRECTLY.

I kept getting this error while rebasing/squishing commits and didn't know why because I had done it before several times.

Didn't matter how many times I would delete the index.lock file, every time it would fail.

Turns out it was because I was using the ATOM EDITOR terminal plugin. Once I used the terminal that ships with Ubuntu it worked like a charm.

The first question is what are your needs? UTF-8 encoding is a pretty good compromise between taking text created with a cheap editor and support for a wide variety of languages. In regards to the browser identifying the encoding, the response (from the web server) should tell the browser the encoding. Still most browsers will attempt to guess, because this is either missing or wrong in so many cases. They guess by reading some amount of the result stream to see if there is a character that does not fit in the default encoding. Currently all browser(? I did not check this, but it is pretty close to true) use utf-8 as the default.

So use utf-8 unless you have a compelling reason to use one of the many other encoding schemes.

Facelets is a XML based view technology. The & is a special character in XML representing the start of an entity like & which ends with the ; character. You'd need to either escape it, which is ugly:

rendered="#{beanA.prompt == true && beanB.currentBase != null}"

or to use the and keyword instead, which is preferred as to readability and maintainability:

rendered="#{beanA.prompt == true and beanB.currentBase != null}"

See also:

• Java EE 6 tutorial - Operators in EL

Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true:

rendered="#{beanA.prompt and beanB.currentBase != null}"

Working test example

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import org.apache.commons.lang3.StringUtils;

public class PaserNo {

    public static void main(String args[]) {

        String text = "gg";

        if (!StringUtils.isBlank(text)) {
            if (stringContainsNumber(text)) {
                int no=Integer.parseInt(text.trim());
                System.out.println("inside"+no);

            } else {
                System.out.println("Outside");
            }
        }
        System.out.println("Done");
    }

    public static boolean stringContainsNumber(String s) {
        Pattern p = Pattern.compile("[0-9]");
        Matcher m = p.matcher(s);
        return m.find();
    }
}

Still your code can be break by "1a" etc so you need to check exception

if (!StringUtils.isBlank(studentNbr)) {
                try{
                    if (isStringContainsNumber(studentNbr)){
                    _account.setStudentNbr(Integer.parseInt(studentNbr.trim()));
                }
                }catch(Exception e){
                    e.printStackTrace();
                    logger.info("Exception during parse studentNbr"+e.getMessage());
                }
            }

Method for checking no is string or not

private boolean isStringContainsNumber(String s) {
        Pattern p = Pattern.compile("[0-9]");
        Matcher m = p.matcher(s);
        return m.find();
    }

FirstOrDefault returns the default value of a type if no item matches the predicate. For reference types that is null. Thats the reason for the exception.

So you just have to check for null first:

string displayName = null;
var keyValue = Dictionary
    .FirstOrDefault(x => x.Value.ID == long.Parse(options.ID));
if(keyValue  != null)
{
    displayName = keyValue.Value.DisplayName;
} 

But what is the key of the dictionary if you are searching in the values? A Dictionary<tKey,TValue> is used to find a value by the key. Maybe you should refactor it.

Another option is to provide a default value with DefaultIfEmpty:

string displayName = Dictionary
    .Where(kv => kv.Value.ID == long.Parse(options.ID))
    .Select(kv => kv.Value.DisplayName)   // not a problem even if no item matches
    .DefaultIfEmpty("--Option unknown--") // or no argument -> null
    .First();                             // cannot cause an exception

To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

let maxDate = new Date(8640000000000000);_x000D_
let minDate = new Date(-8640000000000000);_x000D_
_x000D_
console.log(new Date(maxDate.getTime()).toString());_x000D_
console.log(new Date(maxDate.getTime() - 1).toString());_x000D_
console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

There are two kinds of cell reference, and it's really valuable to understand them well.

One is relative reference, which is what you get when you just type the cell: A5. This reference will be adjusted when you paste or fill the formula into other cells.

The other is absolute reference, and you get this by adding dollar signs to the cell reference: $A$5. This cell reference will not change when pasted or filled.

A cool but rarely used feature is that row and column within a single cell reference may be independent: $A5 and A$5. This comes in handy for producing things like multiplication tables from a single formula.

There is a property className in javascript to change the name of the class of an HTML element. The existing class value will be replaced with the new one, that you have assigned in className.

ls whateveryouwant | xargs -n 1 basename

Does that work for you?

Otherwise you can (cd /the/directory && ls) (yes, parentheses intended)

To find the next element with the same class:

$(".class").eq( $(".class").index( $(element) ) + 1 )

Since you are asking about .NET, you should change the parameter from Long to Integer. .NET's Integer is 32-bit. (Classic VB's integer was only 16-bit.)

Declare Sub Sleep Lib "kernel32.dll" (ByVal Milliseconds As Integer)

Really though, the managed method isn't difficult...

System.Threading.Thread.CurrentThread.Sleep(5000)

Be careful when you do this. In a forms application, you block the message pump and what not, making your program to appear to have hanged. Rarely is sleep a good idea.

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

If your branch is local only and hasn't been pushed to the server, use

git rebase master

Otherwise, use

git merge master

I solved my problem by closing all other projects in eclipse simply.

There's no reason to use es6 features to escape for looping if you're on IE9 or above.

In ES5, there are two good options. First, you can "borrow" Array's forEach as evan mentions.

But even better...

Use Object.keys(), which does have forEach and filters to "own properties" automatically.

That is, Object.keys is essentially equivalent to doing a for... in with a HasOwnProperty, but is much smoother.

var eventNodes = document.getElementsByClassName("events");
Object.keys(eventNodes).forEach(function (key) {
    console.log(eventNodes[key].id);
});

[id] [int] IDENTITY(1,1) NOT NULL,

of course since you're creating the table in SQL Server Management Studio you could use the table designer to set the Identity Specification.

I've found the taglist plug-in a must-have. It lists all tags that it knows about (files that you have opened) in a seperate window and makes it very easy to navigate larger files.

I use it mostly for Python development, but it can only be better for C/C++.

I'd do it like MartinStettner but add an extra parameter for number of digits:

inline HexStruct hex(long n, int w=2)
{
  return HexStruct(n, w);
}
// Rest of implementation is left as an exercise for the reader

So you have two digits by default but can set four, eight, or whatever if you want to.

eg.

int main()
{
  short a = 3142;
  std:cout << hex(a,4) << std::endl;
}

It may seem like overkill but as Bjarne said: "libraries should be easy to use, not easy to write".

All good and valid courses of investigation especially the logs for more info.

For those hitting this it might be a simple gotcha where when you have created the DB User you may have enforced a password policy and left the user to change the password on first login (i.e. left the checkboxes around the password field at their default values).

Very easily done in SQL Management Studio and can of course cause authentication issues off the bat that are masked unless you look into the logs.

const array1 = [{id:1,name:'ganza'},
{id:2,name:'respice dddd'},{id:4,name:'respice dddd'},{id:6,name:'respice dddd'},
{id:7,name:'respice dddd'}];
const array2 = [{id:1,name:'ganza respice'},{id:2,name:'respice'},{id:3,name:'mg'}];

 function mergeTwoArray(array1,array2){

    return array1.map((item,i)=>{
        if(array2[i] && item.id===array2[i].id){
          return array2[i];
          }else{
            return item;
          }
    });
  }

const result = mergeTwoArray(array1,array2);
console.log(result);
//here is the result:  Array [Object { id: 1, name: "ganza respice" },
 Object { id: 2, name: "respice" }, Object { id: 4, name: "respice dddd" }, 
Object { id: 6, name: "respice dddd" }, Object { id: 7, name: "respice dddd" }]

While searching this very question I discovered this example in the documentation.

QPushButton *quitButton = new QPushButton("Quit");
connect(quitButton, &QPushButton::clicked, &app, &QCoreApplication::quit, Qt::QueuedConnection);

Mutatis mutandis for your particular action of course.

Along with this note.

It's good practice to always connect signals to this slot using a QueuedConnection. If a signal connected (non-queued) to this slot is emitted before control enters the main event loop (such as before "int main" calls exec()), the slot has no effect and the application never exits. Using a queued connection ensures that the slot will not be invoked until after control enters the main event loop.

It's common to connect the QGuiApplication::lastWindowClosed() signal to quit()

I had the same problem. Try this.

<nav>
    <ul>
        <li><a href="#">AnaSayfa</a></li>
        <li><a href="#">Hakkimizda</a></li>
        <li><a href="#">Iletisim</a></li>
    </ul>
</nav>

@charset "utf-8";

nav {
    background-color: #9900CC;
    height: 80px;
    width: 400px;
}

ul {
    list-style: none;
    float: right;
    margin: 0;
}

li {
    float: left;
    width: 100px;
    line-height: 80px;
    vertical-align: middle;
    text-align: center;
    margin: 0;
}

nav li a {
    width: 100px;
    text-decoration: none;
    color: #FFFFFF;
}

Inspired from Robert's answer, but when we use,

ng-click="searchAll = null" in the filter, it makes the model values as null and in-turn the search doesn't work with its normal functionality, so it would be better enough to use ng-click="searchAll = ''" instead

Java uses pass-by-value. It is not possible to swap two primitives or objects using a method.

Although it is possible to swap two elements in an integer array.

I needed something like that and the solution I gave with the help of jquery is this:

<textarea class="textlimited" data-textcounterid="counter1" maxlength="30">text</textarea>
<span class='textcounter' id="counter1"></span>

With this script:

// the selector below will catch the keyup events of elements decorated with class textlimited and have a maxlength
$('.textlimited[maxlength]').keyup(function(){
     //get the fields limit
    var maxLength = $(this).attr("maxlength");

    // check if the limit is passed
    if(this.value.length > maxLength){
        return false;
    }

    // find the counter element by the id specified in the source input element
    var counterElement = $(".textcounter#" + $(this).data("textcounterid"));
    // update counter 's text
    counterElement.html((maxLength - this.value.length) + " chars left");
});

This might be useful to someone ending up here from a search. Make sure you're trying to drop a table and not a view.

SET foreign_key_checks = 0;
-- Drop tables
drop table ...
-- Drop views
drop view ...
SET foreign_key_checks = 1;

SET foreign_key_checks = 0 is to set foreign key checks to off and then SET foreign_key_checks = 1 is to set foreign key checks back on. While the checks are off the tables can be dropped, the checks are then turned back on to keep the integrity of the table structure.

Example:

URL imageURL = this.getClass().getClassLoader().getResource("Gui/icon/report-go-icon.png");
ImageIcon iChing = new ImageIcon("C:\\Users\\RrezartP\\Documents\\NetBeansProjects\\Inventari\\src\\Gui\\icon\\report-go-icon.png");      
btnReport.setIcon(iChing); 
System.out.println(imageURL);

For me, I tried the above. Turns out my USB cable was bad. I changed the cable and then it worked.

You can split the processing into a specified number of threads using an approach like this:

import threading

    for item in items[start:end]:                                               
        try:                                                                    
            api.my_operation(item)                                              
        except Exception:                                                       
            print('error with item')                                            


def split_processing(items, num_splits=4):

        end = None if i+1 == num_splits else (i+1) * split_size

You could just use VideoLAN. VideoLAN will work as a server (or you can wrap your own C# application around it for more control). There are also .NET wrappers for the viewer that you can use and thus embed in your C# client.

As I answered previously in Cloning git repo causes error - Host key verification failed. fatal: The remote end hung up unexpectedly, add the GitHub to the list of authorized hosts:

ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts

Yep, you'll want to do something like this:

echo -n "Enter Fullname: " 
read fullname

Another option would be to have them supply this information on the command line. Getopts is your best bet there.

Using getopts in bash shell script to get long and short command line options

You can perform bulk insert using mongoose, as the highest score answer. But the example cannot work, it should be:

/* a humongous amount of potatos */
var potatoBag = [{name:'potato1'}, {name:'potato2'}];

var Potato = mongoose.model('Potato', PotatoSchema);
Potato.collection.insert(potatoBag, onInsert);

function onInsert(err, docs) {
    if (err) {
        // TODO: handle error
    } else {
        console.info('%d potatoes were successfully stored.', docs.length);
    }
}

Don't use a schema instance for the bulk insert, you should use a plain map object.

Handle the dragstart event and return false.

An alternative answer is to reshape the array so that it has dimensions (1, N) like so:

savetext(filename, a.reshape(1, a.shape[0]))

@742's answer works pretty well, but as outlined in the comments when running from the VS debugger the generic icon is still shown.

If you want to have your icon even when you're pressing F5, you can add in the Main Window:

<Window x:Class="myClass"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Icon="./Resources/Icon/myIcon.png">

where you indicate the path to your icon (the icon can be *.png, *.ico.)

(Note you will still need to set the Application Icon or it'll still be the default in Explorer).

I use TeXMaker. If you're using Ubuntu, it should be in the apt-get repository. To install texmaker, run:

sudo apt-get install texmaker

 Label12.Text = Convert.ToInt64(reader[6]).ToString("(###) ###-#### ");

This is my example! I hope can help you with this. regards

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

OutputDebugString function will do it.

example code

    void CClass::Output(const char* szFormat, ...)
{
    char szBuff[1024];
    va_list arg;
    va_start(arg, szFormat);
    _vsnprintf(szBuff, sizeof(szBuff), szFormat, arg);
    va_end(arg);

    OutputDebugString(szBuff);
}

To check if one or more columns all exist, you can use set.issubset, as in:

if set(['A','C']).issubset(df.columns):
   df['sum'] = df['A'] + df['C']                

As @brianpck points out in a comment, set([]) can alternatively be constructed with curly braces,

if {'A', 'C'}.issubset(df.columns):

See this question for a discussion of the curly-braces syntax.

Or, you can use a list comprehension, as in:

if all([item in df.columns for item in ['A','C']]):

There is most likely a connection to the DB from somewhere (a rare example: asynchronous statistic update)

To find connections, use sys.sysprocesses

USE master
SELECT * FROM sys.sysprocesses WHERE dbid = DB_ID('MyDB')

To force disconnections, use ROLLBACK IMMEDIATE

USE master
ALTER DATABASE MyDB SET SINGLE_USER WITH ROLLBACK IMMEDIATE

let dynamic_func_name = 'alert';
let para_1 = 'HAHAHA';
let para_2 = 'ABCD';
(new Function(`${dynamic_func_name}('${para_1}','${para_2}')`))()

Run Dynamic Code:

let some_code = "alert('hahaha');";
(new Function(some_code))()

Use following if value is string (e.g. from <input):

Math.floor(value).toString() !== value

I add .toString() to floor to make it work also for cases when value == "1." (ends with decimal separator or another string). Also Math.floor always returns some value so .toString() never fails.

From Cocoa_(API) Wikipedia:

(emphasis added)

Cocoa classes begin with the acronym "NS" (standing either for the NeXT-Sun creation of OpenStep, or for the original proprietary term for the OpenStep framework, NeXTSTEP): NSString, NSArray, etc.

Foundation Kit, or more commonly simply Foundation, first appeared in OpenStep. On Mac OS X, it is based on Core Foundation. Foundation is a generic object-oriented library providing string and value manipulation, containers and iteration, distributed computing, run loops, and other functions that are not directly tied to the graphical user interface. The "NS" prefix, used for all classes and constants in the framework, comes from Cocoa's OPENSTEP heritage, which was jointly developed by NeXT and Sun.

have you tried flatten? From matplotlib.cbook.flatten(seq, scalarp=) ?

I will bet "flattenlist" I am going to use this rather than matploblib for a long long time unless I want a yield generator and fast result as "flatten" uses in matploblib.cbook

This, is fast.

        else:
            thelist += flattenlist(x)
    return thelist

While editing the code (because mild OCD), I noticed that weather is also a list. You should probably consider something like

echo $data[0]->weather[0]->weatherIconUrl[0]->value;

to make sure you are using the weatherIconUrl for the correct date instance.

import csv
import json
csvfile = csv.DictReader('filename.csv', 'r'))
output =[]
for each in csvfile:
    row ={}
    row['FirstName'] = each['FirstName']
    row['LastName']  = each['LastName']
    row['IDNumber']  = each ['IDNumber']
    row['Message']   = each['Message']
    output.append(row)
json.dump(output,open('filename.json','w'),indent=4,sort_keys=False)

A List<T> is already an IEnumerable<T>, so you can run LINQ statements directly on your List<T> variable.

If you don't see the LINQ extension methods like OrderBy() I'm guessing it's because you don't have a using System.Linq directive in your source file.

You do need to convert the LINQ expression result back to a List<T> explicitly, though:

List<Customer> list = ...
list = list.OrderBy(customer => customer.Name).ToList()

I downgraded via NuGet to MVC 4 and then upgraded again to 5.2.7 and it fixed this issue

It's a conceptual problem.

Stringstream is a stream, so its iterators are forward, cannot return. In an output stringstream, you need a flush() to reinitialize it, as in any other output stream.

A LinkedList can be used as a Queue - but you need to use it right. Here is an example code :

@Test
public void testQueue() {
    LinkedList<Integer> queue = new LinkedList<>();
    queue.add(1);
    queue.add(2);
    System.out.println(queue.pop());
    System.out.println(queue.pop());
}

Output :

1
2

Remember, if you use push instead of add ( which you will very likely do intuitively ), this will add element at the front of the list, making it behave like a stack.

So this is a Queue only if used in conjunction with add.

Try this :

@Test
public void testQueue() {
    LinkedList<Integer> queue = new LinkedList<>();
    queue.push(1);
    queue.push(2);
    System.out.println(queue.pop());
    System.out.println(queue.pop());
}

Output :

2
1

The following code were written in ES6 and it will work in most of the browsers without an issue.

var test_array = [["name1", 2, 3], ["name2", 4, 5], ["name3", 6, 7], ["name4", 8, 9], ["name5", 10, 11]];_x000D_
_x000D_
// Construct the comma seperated string_x000D_
// If a column values contains a comma then surround the column value by double quotes_x000D_
const csv = test_array.map(row => row.map(item => (typeof item === 'string' && item.indexOf(',') >= 0) ? `"${item}"`: String(item)).join(',')).join('\n');_x000D_
_x000D_
// Format the CSV string_x000D_
const data = encodeURI('data:text/csv;charset=utf-8,' + csv);_x000D_
_x000D_
// Create a virtual Anchor tag_x000D_
const link = document.createElement('a');_x000D_
link.setAttribute('href', data);_x000D_
link.setAttribute('download', 'export.csv');_x000D_
_x000D_
// Append the Anchor tag in the actual web page or application_x000D_
document.body.appendChild(link);_x000D_
_x000D_
// Trigger the click event of the Anchor link_x000D_

I add those key in InfoPlist.strings in iOS 8.4, iPad mini 2. It works too. I don't set any key, like NSLocationWhenInUseUsageDescription, in my Info.plist.

InfoPlist.strings:

"NSLocationWhenInUseUsageDescription" = "I need GPS information....";

Base on this thread, it said, as in iOS 7, can be localized in the InfoPlist.strings. In my test, those keys can be configured directly in the file InfoPlist.strings.

So the first thing you need to do is to add one or both of the > following keys to your Info.plist file:

• NSLocationWhenInUseUsageDescription
• NSLocationAlwaysUsageDescription

Both of these keys take a string which is a description of why you need location services. You can enter a string like “Location is required to find out where you are” which, as in iOS 7, can be localized in the InfoPlist.strings file.

UPDATE:

I think @IOS's method is better. Add key to Info.plist with empty value and add localized strings to InfoPlist.strings.

A super key of an entity set is a set of one or more attributes whose values uniquely determine each entity.

A candidate key of an entity set is a minimal super key.

Let's go on with customer, loan and borrower sets that you can find an image from the link == 1

• Rectangles represent entity sets == 1
• Diamonds represent relationship set == 1
• Elipses represent attributes == 1
• Underline indicates Primary Keys == 1

customer_id is the candidate key of the customer set, loan_number is the candidate key of the loan set.

Although several candidate keys may exist, one of the candidate keys is selected to be the primary key.

Borrower set is formed customer_id and loan_number as a relationship set.

Another summary:

You need to use both. ETags are a "server side" information. Expires are a "Client side" caching.

• Use ETags except if you have a load-balanced server. They are safe and will let clients know they should get new versions of your server files every time you change something on your side.

• Expires must be used with caution, as if you set a expiration date far in the future but want to change one of the files immediatelly (a JS file for instance), some users may not get the modified version until a long time!

Take a look at the Clay library:

http://clay.codeplex.com/

It provides something similar to the ExpandoObject but with a bunch of extra features. Here is blog post explaining how to use it:

This is a simple program to capture an image from using a default camera. Also, It can Detect a human face.

import cv2
import sys
import logging as log
import datetime as dt
from time import sleep

cascPath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascPath)
log.basicConfig(filename='webcam.log',level=log.INFO)

video_capture = cv2.VideoCapture(0)
anterior = 0

while True:
    if not video_capture.isOpened():
        print('Unable to load camera.')
        sleep(5)
        pass

    # Capture frame-by-frame
    ret, frame = video_capture.read()

    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    faces = faceCascade.detectMultiScale(
        gray,
        scaleFactor=1.1,
        minNeighbors=5,
        minSize=(30, 30)
    )

    # Draw a rectangle around the faces
    for (x, y, w, h) in faces:
        cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 255, 0), 2)

    if anterior != len(faces):
        anterior = len(faces)
        log.info("faces: "+str(len(faces))+" at "+str(dt.datetime.now()))


    # Display the resulting frame
    cv2.imshow('Video', frame)

    if cv2.waitKey(1) & 0xFF == ord('s'): 

        check, frame = video_capture.read()
        cv2.imshow("Capturing", frame)
        cv2.imwrite(filename='saved_img.jpg', img=frame)
        video_capture.release()
        img_new = cv2.imread('saved_img.jpg', cv2.IMREAD_GRAYSCALE)
        img_new = cv2.imshow("Captured Image", img_new)
        cv2.waitKey(1650)
        print("Image Saved")
        print("Program End")
        cv2.destroyAllWindows()

        break
    elif cv2.waitKey(1) & 0xFF == ord('q'):
        print("Turning off camera.")
        video_capture.release()
        print("Camera off.")
        print("Program ended.")
        cv2.destroyAllWindows()
        break

    # Display the resulting frame
    cv2.imshow('Video', frame)

# When everything is done, release the capture
video_capture.release()
cv2.destroyAllWindows()

Also, You can check out my GitHub code

The real problem is that you are using dynamic return type in the FacebookClient Get method. And although you use a method for serializing, the JSON converter cannot deserialize this Object after that.

Use insted of:

dynamic result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}); 
string jsonstring = JsonConvert.SerializeObject(result);

something like that:

string result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}).ToString();

Then you can use DeserializeObject method:

var datalist = JsonConvert.DeserializeObject<List<RootObject>>(result);

Hope this helps.

I had a similar problem. Given a date, I wanted to get the date of the Monday of that week.

I used the following logic: Find the day number in the week in the range of 0-6, then subtract that from the originay date.

I used: DATEADD(day,-(DATEPART(weekday,)+5)%7,)

Since DATEPRRT(weekday,) returns 1 = Sundaye ... 7=Saturday, DATEPART(weekday,)+5)%7 returns 0=Monday ... 6=Sunday.

Subtracting this number of days from the original date gives the previous Monday. The same technique could be used for any starting day of the week.

compare() will return false (well, 0) if the strings are equal.

So don't take exchanging one for the other lightly.

Use whichever makes the code more readable.

An equivalent alternative to "set -e" is

set -o errexit

It makes the meaning of the flag somewhat clearer than just "-e".

Random addition: to temporarily disable the flag, and return to the default (of continuing execution regardless of exit codes), just use

set +e
echo "commands run here returning non-zero exit codes will not cause the entire script to fail"
echo "false returns 1 as an exit code"
false
set -e

This precludes proper error handling mentioned in other responses, but is quick & effective (just like bash).

public static class StringsEx

    public static IEnumerable<String> Like(this IEnumerable<String> input, String pattern)
    {
        var dt = new DataTable();
        dt.Columns.Add("Search");
        foreach (String str in input)
        {
            dt.Rows.Add(str);
        }
        dt.DefaultView.RowFilter = String.Format("Search LIKE '{0}'", pattern);

            .AsEnumerable()
            .Select(r => r.Field<String>("Search"));
    }
}

The only disadvantage is following: "Wildcard characters are not allowed in the middle of a string. For example, 'te*xt' is not allowed."©

Another way to do this is:

#config/database.php

'profiler' => true

For all Queries result:

print_r(DB::profiler());

For last Result:

print_r(DB::last_query());

This doesn't exactly answer the question but for anyone using AngularJS trying to achieve this, the answer is slightly different. And actually the normal answer won't work (at least it didn't for me).

Your html will look pretty similar to the normal radio button:

<input type='radio' name='group' ng-model='mValue' value='first' />First
<input type='radio' name='group' ng-model='mValue' value='second' /> Second

In your controller you'll have declared the mValue that is associated with the radio buttons. To have one of these radio buttons preselected, assign the $scope variable associated with the group to the desired input's value:

$scope.mValue="second"

This makes the "second" radio button selected on loading the page.

EDIT: Since AngularJS 2.x

The above approach does not work if you're using version 2.x and above. Instead use ng-checked attribute as follows:

<input type='radio' name='gender' ng-model='genderValue' value='male' ng-checked='genderValue === male'/>Male
<input type='radio' name='gender' ng-model='genderValue' value='female' ng-checked='genderValue === female'/> Female

If you do not want to install sqlplus on your server/machine then the following command-line tool can be your friend. It is a simple Java application, only Java 8 that you need in order to you can execute this tool.

The tool can be used to run any SQL from the Linux bash or Windows command line.

Example:

java -jar sql-runner-0.2.0-with-dependencies.jar \
     -j jdbc:oracle:thin:@//oracle-db:1521/ORCLPDB1.localdomain \
     -U "SYS as SYSDBA" \
     -P Oradoc_db1 \
      "select 1 from dual"

Documentation is here.

You can download the binary file from here.

This worked for me.

//used in an ASP.NET MVC app
private const string BatchFilePath = "/MyBatchFileDirectory/Mybatchfiles.bat"; 
var batchFile = HttpContext.Current.Server.MapPath(BatchFilePath);

Optional value allows you to show absence of value. Little bit like NULL in SQL or NSNull in Objective-C. I guess this will be an improvement as you can use this even for "primitive" types.

// Reimplement the Swift standard library's optional type
enum OptionalValue<T> {
    case None
    case Some(T)
}
var possibleInteger: OptionalValue<Int> = .None
possibleInteger = .Some(100)”

Excerpt From: Apple Inc. “The Swift Programming Language.” iBooks. https://itun.es/gb/jEUH0.l

From Typescript 3.7 on, you can also use nullish coalescing:

let x = foo ?? bar();

Which is the equivalent for checking for null or undefined:

let x = (foo !== null && foo !== undefined) ?
    foo :
    bar();

https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#nullish-coalescing

While not exactly the same, you could write your code as:

var uemail = localStorage.getItem("useremail") ?? alert('Undefined');

len(yourdict.keys())

or just

len(yourdict)

If you like to count unique words in the file, you could just use set and do like

len(set(open(yourdictfile).read().split()))

Simply Add 'carousel-item' class in place of item class.

The difference between class and struct is a difference between keywords, not between data types. This two

struct foo : foo_base { int x;};
class bar : bar_base { int x; };

both define a class type. The difference of the keywords in this context is the different default access:

• foo::x is public and foo_base is inherited publicly
• bar::x is private and bar_base is inherited privately

Your best bet will be looking at the WifiManager class. Specifically the setWifiEnabled(bool) function.

See the documentation at: http://developer.android.com/reference/android/net/wifi/WifiManager.html#setWifiEnabled(boolean)

A tutorial on how to use it (including what permissions you need) can be found here: http://www.tutorialforandroid.com/2009/10/turn-off-turn-on-wifi-in-android-using.html

Its late, yet it's worth your time nothing that, there are some differences in browser level implementation of focusin and focusout events and react synthetic onFocus and onBlur. focusin and focusout actually bubble, while onFocus and onBlur dont. So there is no exact same implementation for focusin and focusout as of now for react. Anyway most cases will be covered in onFocus and onBlur.

You should use Asset Catalog:

I have investigated, how we can use Asset Catalog; Now it seems to be easy for me. I want to show you steps to add icons and splash in asset catalog.

Note: No need to make any entry in info.plist file :) And no any other configuration.

In below image, at right side, you will see highlighted area, where you can mention which icons you need. In case of mine, i have selected first four checkboxes; As its for my app requirements. You can select choices according to your requirements.

Now, see below image. As you will select any App icon then you will see its detail at right side selected area. It will help you to upload correct resolution icon.

If Correct resolution image will not be added then following warning will come. Just upload the image with correct resolution.

After uploading all required dimensions, you shouldn't get any warning.

This question is asked in a lot of places in a lot of different ways. I originally answered it here but I feel it's relevant in this thread as well (since i ended up here when I was searching for an answer).

There is no one line solution to this problem, but this worked for my use case. The problem is, the 'View(context, attrs, defStyle)' constructor does not refer to an actual style, it wants an attribute. So, we will:

1. Define an attribute
2. Create a style that you want to use
3. Apply a style for that attribute on our theme
4. Create new instances of our view with that attribute

In 'res/values/attrs.xml', define a new attribute:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr name="customTextViewStyle" format="reference"/>
    ...
</resources>    

In res/values/styles.xml' I'm going to create the style I want to use on my custom TextView

<style name="CustomTextView">
    <item name="android:textSize">18sp</item>
    <item name="android:textColor">@color/white</item>
    <item name="android:paddingLeft">14dp</item>
</style>

In 'res/values/themes.xml' or 'res/values/styles.xml', modify the theme for your application / activity and add the following style:

<resources>
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <item name="@attr/customTextViewStyle">@style/CustomTextView</item>
    </style>
    ... 
</resources>

Finally, in your custom TextView, you can now use the constructor with the attribute and it will receive your style

public class CustomTextView extends TextView {

    public CustomTextView(Context context) {
       super(context, null, R.attr.customTextView);
    }
}

It's worth noting that I repeatedly used customTextView in different variants and different places, but it is in no way required that the name of the view match the style or the attribute or anything. Also, this technique should work with any custom view, not just TextViews.

There's an Abstract Class Dictionary

http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html

However this requires implementation.

Java gives us a nice implementation called a Hashtable

http://docs.oracle.com/javase/6/docs/api/java/util/Hashtable.html

If you are looking for a shell utility to do something like that, you can use the cut command.

To take your example, try:

echo "abcdefg" | cut -c3-5

which yields

cde

Where -cN-M tells the cut command to return columns N to M, inclusive.

Actually.

Why are you checking the URL? That's no guarantee what you're going to get is an image, and no guarantee that the things you're rejecting aren't images. Try performing a HEAD request on it, and see what content-type it actually is.

You can use the ps command to take a look at the running containers:

docker ps -a

From there you should see the name of your container along with the container ID that you're looking for. Here's more information about docker ps.

You can use a \r (carriage return) to return the cursor to the beginning of the line:

printf("hello");
printf("\rbye");

This will print bye on the same line. It won't erase the existing characters though, and because bye is shorter than hello, you will end up with byelo. To erase it you can make your new print longer to overwrite the extra characters:

printf("hello");
printf("\rbye  ");

Or, first erase it with a few spaces, then print your new string:

printf("hello");
printf("\r          ");
printf("\rbye");

That will print hello, then go to the beginning of the line and overwrite it with spaces, then go back to the beginning again and print bye.

I think you hit the same issue as discussed in this post. You forgot to escape your \ character.

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

This is what I usually do ,please refer my function below :

This function can extract first number occurance from any string you can modify and use this function according to your usage

   public static int GetFirstNumber(this string strInsput)
    {
        int number = 0;
        string strNumber = "";
        bool bIsContNo = true;
        bool bNoOccued = false;

        try
        {
            var arry = strInsput.ToCharArray(0, strInsput.Length - 1);

            foreach (char item in arry)
            {
                if (char.IsNumber(item))
                {
                    strNumber = strNumber + item.ToString();

                    bIsContNo = true;

                    bNoOccued = true;
                }
                else
                {
                    bIsContNo = false;
                }

                if (bNoOccued && !bIsContNo)
                {
                    break;
                }


            }

            number = Convert.ToInt32(strNumber);

        }
        catch (Exception ex)
        {

            return 0;
        }

        return number;

    }

__all__ is very good - it helps guide import statements without automatically importing modules http://docs.python.org/tutorial/modules.html#importing-from-a-package

using __all__ and import * is redundant, only __all__ is needed

I think one of the most powerful reasons to use import * in an __init__.py to import packages is to be able to refactor a script that has grown into multiple scripts without breaking an existing application. But if you're designing a package from the start. I think it's best to leave __init__.py files empty.

for example:

foo.py - contains classes related to foo such as fooFactory, tallFoo, shortFoo

then the app grows and now it's a whole folder

foo/
    __init__.py
    foofactories.py
    tallFoos.py
    shortfoos.py
    mediumfoos.py
    santaslittlehelperfoo.py
    superawsomefoo.py
    anotherfoo.py

then the init script can say

__all__ = ['foofactories', 'tallFoos', 'shortfoos', 'medumfoos',
           'santaslittlehelperfoo', 'superawsomefoo', 'anotherfoo']
# deprecated to keep older scripts who import this from breaking
from foo.foofactories import fooFactory
from foo.tallfoos import tallFoo
from foo.shortfoos import shortFoo

so that a script written to do the following does not break during the change:

from foo import fooFactory, tallFoo, shortFoo

Make sure, you've run composer update on your server instance.

I created a VB script and run it either from command line or from a Java process. I also tried to catch errors when creating the shortcut so I can have a better error handling.

Set oWS = WScript.CreateObject("WScript.Shell")
shortcutLocation = Wscript.Arguments(0)

'error handle shortcut creation
On Error Resume Next
Set oLink = oWS.CreateShortcut(shortcutLocation)
If Err Then WScript.Quit Err.Number

'error handle setting shortcut target
On Error Resume Next
oLink.TargetPath = Wscript.Arguments(1)
If Err Then WScript.Quit Err.Number

'error handle setting start in property
On Error Resume Next
oLink.WorkingDirectory = Wscript.Arguments(2)
If Err Then WScript.Quit Err.Number

'error handle saving shortcut
On Error Resume Next
oLink.Save
If Err Then WScript.Quit Err.Number

I run the script with the following commmand:

cscript /b script.vbs shortcutFuturePath targetPath startInProperty

It is possible to have it working even without setting the 'Start in' property in some cases.

This is a feature called template literals.

They were called "template strings" in prior editions of the ECMAScript 2015 specification.

Template literals are supported by Firefox 34, Chrome 41, and Edge 12 and above, but not by Internet Explorer.

• Examples: http://tc39wiki.calculist.org/es6/template-strings/
• Official specification: ECMAScript 2015 Language Specification, 12.2.9 Template Literal Lexical Components (a bit dry)

Template literals can be used to represent multi-line strings and may use "interpolation" to insert variables:

var a = 123, str = `---
   a is: ${a}
---`;
console.log(str);

Output:

---
   a is: 123
---

What is more important, they can contain not just a variable name, but any JavaScript expression:

var a = 3, b = 3.1415;

console.log(`PI is nearly ${Math.max(a, b)}`);

Quick google search says you can embed it like this:

<img src="data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub/

width="16" height="14" alt="embedded folder icon">

But you need a different implementation in Internet Explorer.

http://www.websiteoptimization.com/speed/tweak/inline-images/

One option would be to use a helper extension method like follows:

public static class MyExtensions
{
    public static System.Type Type<T>(this T v)=>typeof(T);
}

var i=0;
console.WriteLine(i.Type().FullName);

Since 0.14 this method won't work, so I built a static component that will make this simple for you guys. You can just paste this in or reference it as a component.

This should be re-useable and it will allow you to add additional styles and properties as-if it were a standard <Image /> component

const BackgroundImage = ({ source, children, style, ...props }) => {
  return (
      <Image
        source={source}
        style={{flex: 1, width: null, height: null, ...style}}
        {...props}>
        {children}
      </Image>
  );
}

just paste this in and then you can use it like image and it should fit the entire size of the view it is in (so if it's the top view it will fill your screen.

<BackgroundImage source={require('../../assets/backgrounds/palms.jpg')}>
    <Scene styles={styles} {...store} />
</BackgroundImage>

All scripts should be imported in order:

1. jQuery and Moment.js
2. Bootstrap js file
3. Bootstrap datepicker js file

Bootstrap-datetimepicker requires moment.js to be loaded before datepicker.js.

Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories, and it should work.

The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.

You need to output ANSI colour codes. Note that not all terminals support this; if colour sequences are not supported, garbage will show up.

Example:

 cout << "\033[1;31mbold red text\033[0m\n";

Here, \033 is the ESC character, ASCII 27. It is followed by [, then zero or more numbers separated by ;, and finally the letter m. The numbers describe the colour and format to switch to from that point onwards.

The codes for foreground and background colours are:

         foreground background
black        30         40
red          31         41
green        32         42
yellow       33         43
blue         34         44
magenta      35         45
cyan         36         46
white        37         47

Additionally, you can use these:

reset             0  (everything back to normal)
bold/bright       1  (often a brighter shade of the same colour)
underline         4
inverse           7  (swap foreground and background colours)
bold/bright off  21
underline off    24
inverse off      27

See the table on Wikipedia for other, less widely supported codes.

To determine whether your terminal supports colour sequences, read the value of the TERM environment variable. It should specify the particular terminal type used (e.g. vt100, gnome-terminal, xterm, screen, ...). Then look that up in the terminfo database; check the colors capability.

Update: Sep 2019

As a few people have mentioned, the parameters in paramMap should be accessed using the common MapAPI:

To get a snapshot of the params, when you don't care that they may change:

this.bankName = this.route.snapshot.paramMap.get('bank');

To subscribe and be alerted to changes in the parameter values (typically as a result of the router's navigation)

this.route.paramMap.subscribe( paramMap => {
    this.bankName = paramMap.get('bank');
})

Update: Aug 2017

Since Angular 4, params have been deprecated in favor of the new interface paramMap. The code for the problem above should work if you simply substitute one for the other.

Original Answer

If you inject ActivatedRoute in your component, you'll be able to extract the route parameters

    import {ActivatedRoute} from '@angular/router';
    ...
    
    constructor(private route:ActivatedRoute){}
    bankName:string;
    
    ngOnInit(){
        // 'bank' is the name of the route parameter
        this.bankName = this.route.snapshot.params['bank'];
    }

If you expect users to navigate from bank to bank directly, without navigating to another component first, you ought to access the parameter through an observable:

    ngOnInit(){
        this.route.params.subscribe( params =>
            this.bankName = params['bank'];
        )
    }

For the docs, including the differences between the two check out this link and search for "activatedroute"

Using a RegExp to replace any non digit. Take care the next code will give you the first digit he found, so if user paste a paragraph with more than one number (xx.xx) the code will give you the first number. This will help if you want something like price, not a mobile phone.

Use this for your onTextChange handler:

onChanged (text) {
    this.setState({
        number: text.replace(/[^(((\d)+(\.)\d)|((\d)+))]/g,'_').split("_"))[0],
    });
}

As this is tagged with the extjs tag it may be worth looking at the extjs method: http://docs.sencha.com/extjs/6.2.0/classic/Ext.Function.html#method-interval

This works much like setInterval, but also takes care of the scope, and allows arguments to be passed too:

function setBgPosition() {
    var c = 0;
    var numbers = [0, -120, -240, -360, -480, -600, -720];
    function run() {
       Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
        if (c<numbers.length){
            c=0;
        }
    }
    return Ext.Function.interval(run,200);
}

var bgPositionTimer = setBgPosition();

when you want to stop you can use clearInterval to stop it

clearInterval(bgPositionTimer);

An example use case would be:

Ext.Ajax.request({
    url: 'example.json',

    success: function(response, opts) {
        clearInterval(bgPositionTimer);
    },

    failure: function(response, opts) {
        console.log('server-side failure with status code ' + response.status);
        clearInterval(bgPositionTimer);
    }
});

I don't know which version of Jquery you are using, but this works for me in jquery 1.3:

$.ajax({
    type: 'POST', 
    url: your url,
    data: $('#'+form_id).serialize(), 
    success: function(data) {
        $('#debug').html(data);
  }
});

Then you can access POST array keys as you would normally do in php. Just try with a print_r().

I think you're wrapping serialized form value in an object's property, which is useless as far as i know.

Hope this helps!

I know I am posting this answer little late, but I felt it is worth using Google's fuse location provider service to get the current location.

Main features of this api are :

1.Simple APIs: Lets you choose your accuracy level as well as power consumption.

2.Immediately available: Gives your apps immediate access to the best, most recent location.

3.Power-efficiency: It chooses the most efficient way to get the location with less power consumptions

4.Versatility: Meets a wide range of needs, from foreground uses that need highly accurate location to background uses that need periodic location updates with negligible power impact.

It is flexible in while updating in location also. If you want current location only when your app starts then you can use getLastLocation(GoogleApiClient) method.

If you want to update your location continuously then you can use requestLocationUpdates(GoogleApiClient,LocationRequest, LocationListener)

You can find a very nice blog about fuse location here and google doc for fuse location also can be found here.

Update

According to developer docs starting from Android O they have added new limits on background location.

If your app is running in the background, the location system service computes a new location for your app only a few times each hour. This is the case even when your app is requesting more frequent location updates. However if your app is running in the foreground, there is no change in location sampling rates compared to Android 7.1.1 (API level 25).

Just remove the inner quotes - they confuse Firefox. You can just use "video/ogg; codecs=theora,vorbis".

Also, that markup works in my Minefiled 3.7a5pre, so if your ogv file doesn't play, it may be a bogus file. How did you create it? You might want to register a bug with Firefox.

The debug compilation is different from the release one, so:

Consider your Project file structure like that [this case if for a Debug assemble]:

src
  |
  debug
      |
      assets
           |
           index.html

You should call index.html into your WebView like:

web.loadUrl("file:///android_asset/index.html");

So forth, for the Release assemble, it should be like:

src
  |
  release
        |
        assets
             |
             index.html

The bellow structure also works, for both compilations [debug and release]:

src
  |
  main
     |
     assets
          |
          index.html

Test if the a variable is an array before getting the first element. When dynamically creating the array if it is set to null you get an error.

For Example:

if(is_array($array))
{
  reset($array);
  $first = key($array);
}

The following is slower than the approaches timed here, but we can compute the extra column based on the contents of more than one column, and more than two values can be computed for the extra column.

Simple example using just the "Set" column:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Example with more colours and more columns taken into account:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    elif row["Type"] == "C":
        return "blue"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C   blue

Edit (21/06/2019): Using plydata

It is also possible to use plydata to do this kind of things (this seems even slower than using assign and apply, though).

from plydata import define, if_else

Simple if_else:

df = define(df, color=if_else('Set=="Z"', '"red"', '"green"'))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Nested if_else:

df = define(df, color=if_else(
    'Set=="Z"',
    '"red"',
    if_else('Type=="C"', '"green"', '"blue"')))

print(df)                            

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B   blue
3   Y    C  green

On Ubuntu, the recommended way of changing the default library path for a user, is to set the R_LIBS_USER variable in the ~/.Renviron file.

touch ~/.Renviron
echo "R_LIBS_USER=/custom/path/in/absolute/form" >> ~/.Renviron

You can do this:

Change the package name manually in the manifest file. Click on your R.java class and the press F6 (Refactor->Move...). It will allow you to move the class to other package, and all references to that class will be updated.

reference: How do I rename the android package name?

Another option would be to simply use grepl function:

df[grepl('er', df$name), ]
CO2[grepl('non', CO2$Treatment), ]

df <- data.frame(name = c('bob','robert','peter'),
                 id = c(1,2,3)
                 )

# name id
# 2 robert  2
# 3  peter  3

I'm not sure if I understand your question properly, but it shouldn't matter if this div is a child of some other div. You can simply get text from all divs with class bgHeaderH2 by using following code:

$(".bgHeaderH2").text();

until passwd
do
  echo "Try again"
done

or

while ! passwd
do
  echo "Try again"
done

If you are just storing it for reference, you can store it as a string, but if you want to do a lookup, for example, to see if the IP address is in some table, you need a "canonical representation." Converting the entire thing to a (large) number is the right thing to do. IPv4 addresses can be stored as a long int (32 bits) but you need a 128 bit number to store an IPv6 address.

For example, all these strings are really the same IP address: 127.0.0.1, 127.000.000.001, ::1, 0:0:0:0:0:0:0:1

Just add the following line to your code before print.

 pd.options.display.max_colwidth = 90  # set a value as your need

You can simply do the following steps for setting other additional options,

• You can change the options for pandas max_columns feature as follows to display more columns

  import pandas as pd
  pd.options.display.max_columns = 10
  

  (this allows 10 columns to display, you can change this as you need)

• Like that you can change the number of rows as you need to display as follows to display more rows

  pd.options.display.max_rows = 999
  

  (this allows to print 999 rows at a time)

this should works fine

Please kindly refer the doc to change more options/settings for pandas

In "Javascript 1.7" (Mozilla's extension to Javascript) one can also declare block-scope variables with let statement:

 var a = 4;
 let (a = 3) {
   alert(a); // 3
 }
 alert(a);   // 4

See my jsFiddle here: http://jsfiddle.net/fuDBL/

Whenever you change the email field, the link is updated automatically. This requires a small amount of jQuery. So now your form will work as needed, but your link will be updated dynamically so that when someone clicks on it, it contains what they entered in the email field. You should validate the input on the receiving page.

$('input[name="email"]').change(function(){
  $('#regLink').attr('href')+$('input[name="email"]').val();
});

You can use virtualenv --clear. which won't install any packages, then install the ones you want.

Just for people looking to do this in batch files, this code is working:

FOR /R "C:\Users\jonathan\Desktop\test" %%f IN (*.jpg) DO REN "%%f" *.png

In this example all files with .jpg extensions in the C:\Users\jonathan\Desktop\test directory are changed to *.png.

The & makes the command run in the background.

From man bash:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0.

Swift 2.0:

Using extension method:

extension UIImage{

   class func renderUIViewToImage(viewToBeRendered:UIView?) -> UIImage
   {
       UIGraphicsBeginImageContextWithOptions((viewToBeRendered?.bounds.size)!, false, 0.0)
       viewToBeRendered!.drawViewHierarchyInRect(viewToBeRendered!.bounds, afterScreenUpdates: true)
       viewToBeRendered!.layer.renderInContext(UIGraphicsGetCurrentContext()!)

       let finalImage = UIGraphicsGetImageFromCurrentImageContext()
       UIGraphicsEndImageContext()

       return finalImage
   }

}

Usage:

override func viewDidLoad() {
    super.viewDidLoad()

    //Sample View To Self.view
    let sampleView = UIView(frame: CGRectMake(100,100,200,200))
    sampleView.backgroundColor =  UIColor(patternImage: UIImage(named: "ic_120x120")!)
    self.view.addSubview(sampleView)    

    //ImageView With Image
    let sampleImageView = UIImageView(frame: CGRectMake(100,400,200,200))

    //sampleView is rendered to sampleImage
    var sampleImage = UIImage.renderUIViewToImage(sampleView)

    sampleImageView.image = sampleImage
    self.view.addSubview(sampleImageView)

 }

I'm one of the developers behind the Cryptolens software licensing platform and have been working on licensing systems since the age of 14. In this answer, I have included some tips based on experience acquired over the years.

The best way of solving this is by setting up a license key server that each instance of the application will call in order to verify a license key.

Benefits of a license key server

The advantages with a license key server is that:

1. you can always update or block a license key with immediate effect.
2. each license key can be locked to certain number of machines (this helps to prevent users from publishing the license key online for others to use).

Considerations

Although verifying licenses online gives you more control over each instance of the application, internet connection is not always present (especially if you target larger enterprises), so we need another way of performing the license key verification.

The solution is to always sign the license key response from the server using a public-key cryptosystem such as RSA or ECC (possibly better if you plan to run on embedded systems). Your application should only have the public key to verify the license key response.

So in case there's no internet connection, you can use the previous license key response instead. Make sure to store both the date and the machine identifier in the response and check that it's not too old (eg. you allow users to be offline at most 30 days, etc) and that the license key response belongs to the correct device.

Note you should always check the certificate of license key response, even if you are connected to the internet), in order to ensure that it has not been changed since it left the server (this still has to be done even if your API to the license key server uses https)

Protecting secret algorithms

Most .NET applications can be reverse engineered quite easily (there is both a diassembler provided by Microsoft to get the IL code and some commercial products can even retrieve the source code in eg. C#). Of course, you can always obfuscate the code, but it's never 100% secure.

I most cases, the purpose of any software licensing solution is to help honest people being honest (i.e. that honest users who are willing to pay don't forget to pay after a trial expires, etc).

However, you may still have some code that you by no means want to leak out to the public (eg. an algorithm to predict stock prices, etc). In this case, the only way to go is to create an API endpoint that your application will call each time the method should be executed. It requires internet connection but it ensures that your secret code is never executed by the client machine.

Implementation

If you don't want to implement everything yourself, I would recommend to take a look at this tutorial (part of Cryptolens)

After a detailed investigation, this issue seems to happen every time after Mac OS X is rebooted (or the Docker virtual machine is restarted) which prevents the Docker client from connecting to the Docker daemon.

To solve the issue, you can either:

A) Reinstall Docker Toolbox using the official installer (https://www.docker.com/products/docker-toolbox), or simply

B) Run the following commands in order:

# First make sure that the virtual machine is running
docker-machine start default

# Regenerate TLS connection certs, requires confirmation
docker-machine regenerate-certs default

# Finally, set env
eval "$(docker-machine env default)"

C) Same as (B), you can also copy and paste the following line to run all of the three commands:

docker-machine start default; docker-machine regenerate-certs default; eval "$(docker-machine env default)"

In case you get the following error:

Error getting SSH command: Something went wrong running an SSH command!
command : cat /etc/os-release
err     : exit status 255
output  :

just re-run the three commands another time, and it should work the second time.

Had the same issue with Ionic routing.

Simple solution is to use the name of the state - basically state.go(state name)

.state('tab.search', {
    url: '/search',
    views: {
      'tab-search': {
        templateUrl: 'templates/search.html',
        controller: 'SearchCtrl'
      }
    }
  })

And in controller you can use $state.go('tab.search');

Isn't this the same as updateOrCreate()?

It is similar but not the same. The updateOrCreate() will only work for one row at a time which doesn't allow bulk insert. InsertOnDuplicateKey will work on many rows.

https://github.com/yadakhov/insert-on-duplicate-key

use below code

 Task.WaitAll(Task.Run(async () => await GetResponse<MyObject>("my url")));

You can use pandas, by transforming the list to a pd.Series then simply use .value_counts()

import pandas as pd
a = ['1', '1', '1', '1', '1', '1', '2', '2', '2', '2', '7', '7', '7', '10', '10']
a_cnts = pd.Series(a).value_counts().to_dict()

Input  >> a_cnts["1"], a_cnts["10"]
Output >> (6, 2)

in this case use git add and integrate all pending files and then use git commit and then git push

git add - integrate all pedent files

git commit - save the commit

git push - save to repository

Awesome answers are already given but this is a different way to deal with this situation (using Swift 3x):

First of all call the following method in viewWillAppear()

func registerForKeyboardNotifications() {

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWasShown), name: NSNotification.Name.UIKeyboardDidShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillBeHidden), name: NSNotification.Name.UIKeyboardWillHide, object: nil)

}

Now take one IBOutlet of UIView's top constraints of your UIViewcontroller like this: (here the UIView is the subview of UIScrollView that means you should have a UIScrollView for all your subViews)

@IBOutlet weak var loginViewTopConstraint: NSLayoutConstraint!

And an another variable like following and add a delegate i.e. UITextFieldDelegate:

var activeTextField = UITextField() //This is to keep the reference of UITextField currently active

After that here is the magical part just paste this below snippet:

func keyboardWasShown(_ notification: Notification) {

let keyboardInfo  = notification.userInfo as NSDictionary?

//print(keyboardInfo!)

let keyboardFrameEnd: NSValue? = (keyboardInfo?.value(forKey: UIKeyboardFrameEndUserInfoKey) as? NSValue)

let keyboardFrameEndRect: CGRect? = keyboardFrameEnd?.cgRectValue


if activeTextField.frame.origin.y + activeTextField.frame.size.height + 10 > (keyboardFrameEndRect?.origin.y)! {

    UIView.animate(withDuration: 0.3, delay: 0, options: .transitionFlipFromTop, animations: {() -> Void in

        //code with animation

        //Print some stuff to know what is actually happening
        //print(self.activeTextField.frame.origin.y)
        //print(self.activeTextField.frame.size.height)
        //print(self.activeTextField.frame.size.height)

        self.loginViewTopConstraint.constant = -(self.activeTextField.frame.origin.y + self.activeTextField.frame.size.height - (keyboardFrameEndRect?.origin.y)!) - 30.0

        self.view.layoutIfNeeded()

    }, completion: {(_ finished: Bool) -> Void in
        //code for completion

    })
}
}

func keyboardWillBeHidden(_ notification: Notification) {

UIView.animate(withDuration: 0.3, animations: {() -> Void in

    self.loginViewTopConstraint.constant = self.view.frame.origin.y
    self.view.layoutIfNeeded()

})
}

//MARK: textfield delegates
func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
    activeTextField = textField
    return true
}

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

           switch textField {
    case YOUR_TEXTFIELD_ONE:
        YOUR_TEXTFIELD_TWO.becomeFirstResponder()
        break
    case YOUR_TEXTFIELD_TWO:
        YOUR_TEXTFIELD_THREE.becomeFirstResponder()
        break
    default:
        textField.resignFirstResponder()
        break
    }
    return true
}

Now the last snippet:

//Remove Keyboard Observers
override func viewWillDisappear(_ animated: Bool) {

NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardDidShow, object: nil)

NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

Don't forget to assign delegates to all your UITextFields in UIStoryboard

Good luck!

Run it on a single command line like so:

powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile 
  -WindowStyle Hidden -Command "Get-AppLockerFileInformation -Directory <folderpath> 
  -Recurse -FileType <type>"

Yes, use os.path.exists().

SELECT id, 
       IF(type = 'P', amount, amount * -1) as amount
FROM report

See http://dev.mysql.com/doc/refman/5.0/en/control-flow-functions.html.

Additionally, you could handle when the condition is null. In the case of a null amount:

SELECT id, 
       IF(type = 'P', IFNULL(amount,0), IFNULL(amount,0) * -1) as amount
FROM report

The part IFNULL(amount,0) means when amount is not null return amount else return 0.

This will work on Snowflake (credit to Darren Gardner):

create temp table ss (id int, val int);
insert into ss (id,val) select 1, 3;
insert into ss (id,val) select 2, null;
insert into ss (id,val) select 3, 5;
insert into ss (id,val) select 4, null;
insert into ss (id,val) select 5, null;
insert into ss (id,val) select 6, 2;

select *
      ,last_value(val ignore nulls) over 
       (order by id rows between unbounded preceding and current row) as val2
  from ss;

I had the same issue and concern over duplicate code in two or more sprocs. I ended up adding an additional attribute for "mode". This allowed common code to exist inside one sproc and the mode directed flow and result set of the sproc.

SELECT *
FROM A.tableA JOIN B.tableB 

or

SELECT *
  FROM A.tableA JOIN B.tableB
  ON A.tableA.id = B.tableB.a_id;

301 is a cacheable response per HTTP RFC and browsers will cache it depending on the HTTP caching headers you have on the response. Use FireBug or Charles to examine response headers to know the exact duration the response will be cached for.

If you would like to control the caching duration, you can use the the HTTP response headers Cache-Control and Expires to do the same. Alternatively, if you don't want to cache the 301 response at all, use the following headers.

Cache-Control: no-store, no-cache, must-revalidate
Expires: Thu, 01 Jan 1970 00:00:00 GMT

# Set element with index
$("#select option:eq(2)").attr("selected", "selected");

# Set element by text
$("#select").val("option Text").attr("selected", "selected");

when you want to select with top ways for set selection , you can use
$('#select option').removeAttr('selected'); for remove previous selects .

# Set element by value
$("#select").val("2");

# Get selected text
$("#select").children("option:selected").text();  # use attr() for get attributes
$("#select option:selected").text(); # use attr() for get attributes 

# Get selected value
$("#select option:selected").val();
$("#select").children("option:selected").val();
$("#select option:selected").prevAll().size();
$("option:selected",this).val();

# Get selected index
$("#select option:selected").index();
$("#select option").index($("#select option:selected"));

# Select First Option
$("#select option:first");

# Select Last Item
$("#select option:last").remove();


# Replace item with new one
$("#select option:eq(1)").replaceWith("<option value='2'>new option</option>");

# Remove an item
$("#select option:eq(0)").remove();

It is not what is asked directly. But looking for how to do drop tables properly, I stumbled over this question, as I guess many others do too.

From SQL Server 2016+ you can use

DROP TABLE IF EXISTS dbo.Table

For SQL Server <2016 what I do is the following for a permanent table

IF OBJECT_ID('dbo.Table', 'U') IS NOT NULL 
  DROP TABLE dbo.Table; 

Or this, for a temporary table

IF OBJECT_ID('tempdb.dbo.#T', 'U') IS NOT NULL
  DROP TABLE #T; 

Another option is to create a exclude list, this is particulary usefull when you have a long list of things to exclude.

vi /root/scripts/exclude_list.txt

Now add what you would like to exclude

Nopaging the limit is
keyword to remove is

Now use grep to remove lines from your file log file and view information not excluded.

grep -v -f /root/scripts/exclude_list.txt /var/log/admin.log

Get the router from the container.

$router = $this->get('router');

Then use the router to generate the Url

$uri = $router->generate('blog_show', array('slug' => 'my-blog-post'));
