Fan out was clearly what you wanted. fanout

read rabbitMQ tutorial: https://www.rabbitmq.com/tutorials/tutorial-three-javascript.html

here's my example:

Publisher.js:

amqp.connect('amqp://<user>:<pass>@<host>:<port>', async (error0, connection) => {
    if (error0) {
      throw error0;
    }
    console.log('RabbitMQ connected')
    try {
      // Create exchange for queues
      channel = await connection.createChannel()
      await channel.assertExchange(process.env.EXCHANGE_NAME, 'fanout', { durable: false });
      await channel.publish(process.env.EXCHANGE_NAME, '', Buffer.from('msg'))
    } catch(error) {
      console.error(error)
    }
})

Subscriber.js:

amqp.connect('amqp://<user>:<pass>@<host>:<port>', async (error0, connection) => {
    if (error0) {
      throw error0;
    }
    console.log('RabbitMQ connected')
    try {
      // Create/Bind a consumer queue for an exchange broker
      channel = await connection.createChannel()
      await channel.assertExchange(process.env.EXCHANGE_NAME, 'fanout', { durable: false });
      const queue = await channel.assertQueue('', {exclusive: true})
      channel.bindQueue(queue.queue, process.env.EXCHANGE_NAME, '')

      console.log(" [*] Waiting for messages in %s. To exit press CTRL+C");
      channel.consume('', consumeMessage, {noAck: true});
    } catch(error) {
      console.error(error)
    }
});

here is an example i found in the internet. maybe can also help. https://www.codota.com/code/javascript/functions/amqplib/Channel/assertExchange

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

I am sure the following code will help you to get ip address.

<script type="application/javascript">
    function getip(json){
      alert(json.ip); // alerts the ip address
    }
</script>

<script type="application/javascript" src="http://www.telize.com/jsonip?callback=getip"></script>

There once was a caveman

function caveman {

who had a very special rock,

var rock = "diamond";

You could not get the rock yourself because it was in the caveman's private cave. Only the caveman knew how to find and get the rock.

return {
    getRock: function() {
        return rock;
    }
};
}

Luckily, he was a friendly caveman, and if you were willing to wait for his return, he would gladly get it for you.

var friend = caveman();
var rock = friend.getRock();

Pretty smart caveman.

Double.MAX_VALUE is the maximum value a double can represent (somewhere around 1.7*10^308).

This should end in some calculation problems, if you try to subtract the maximum possible value of a data type.

Even though when you are dealing with money you should never use floating point values especially while rounding this can cause problems (you will either have to much or less money in your system then).

std::find().

One method to do this is to add:

pointer-events: none;

to the element, you want to disable hover on.

(Note: this also disables javascript events on that element too, click events will actually fall through to the element behind ).

Browser Support ( 98.12% as of Jan 1, 2021 )

This seems to be much cleaner

/**
 * This allows you to disable hover events for any elements
*/
.disabled {
  pointer-events: none;  /* <----------- */
  opacity: 0.2;
}

.button {
  border-radius: 30px;
  padding: 10px 15px;
  border: 2px solid #000;
  color: #FFF;
  background: #2D2D2D;
  text-shadow: 1px 1px 0px #000;
  cursor: pointer;
  display: inline-block;
  margin: 10px;
}

.button-red:hover {
  background: red;
}

.button-green:hover {
  background:green;  
}

<div class="button button-red">I'm a red button hover over me</div>

<br />

<div class="button button-green">I'm a green button hover over me</div>

<br />

<div class="button button-red disabled">I'm a disabled red button</div>

<br />

<div class="button button-green disabled">I'm a disabled green button</div>

Using REQUIRES_NEW is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED - it will create a new transaction.

That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional, it will create a new transaction.

So, with that in mind, if using REQUIRES_NEW makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.

On rollback - using REQUIRES_NEW will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations. Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.

If you place image and css folder inside a parent directory suppose assets then the following code works perfectly. Either double quote or without a double quote both work fine.

body{_x000D_
   background: url("../image/bg.jpg");_x000D_
}

In other cases like if you call a class and try to put a background image in a particular location then you must mention height and width as well.

Shorter form:

# if $DIR is a directory, then print yes
[ -d "$DIR" ] && echo "Yes"

More simple way...:

    Dim dt As DataTable = DirectCast(GridView1.DataSource, DataTable)
    Dim dv As New DataView(dt)

    If GridView1.Attributes("dir") = SortDirection.Ascending Then
        dv.Sort = e.SortExpression & " DESC" 
        GridView1.Attributes("dir") = SortDirection.Descending

    Else
        GridView1.Attributes("dir") = SortDirection.Ascending
        dv.Sort = e.SortExpression & " ASC"

    End If

    GridView1.DataSource = dv
    GridView1.DataBind()

In the latest mongoose (3.8.1 at the time of writing), you do two things differently: (1) you have to pass single argument to sort(), which must be an array of constraints or just one constraint, and (2) execFind() is gone, and replaced with exec() instead. Therefore, with the mongoose 3.8.1 you'd do this:

var q = models.Post.find({published: true}).sort({'date': -1}).limit(20);
q.exec(function(err, posts) {
     // `posts` will be of length 20
});

or you can chain it together simply like that:

models.Post
  .find({published: true})
  .sort({'date': -1})
  .limit(20)
  .exec(function(err, posts) {
       // `posts` will be of length 20
  });

Answer from different solutions to get Display Resolution

1. Get the scaling factor

2. Get Screen.PrimaryScreen.Bounds.Width and Screen.PrimaryScreen.Bounds.Height multiple by scaling factor result

   #region Display Resolution
   
    [DllImport("gdi32.dll", CharSet = CharSet.Auto, SetLastError = true, ExactSpelling = true)]
    public static extern int GetDeviceCaps(IntPtr hDC, int nIndex);
   
    public enum DeviceCap
    {
        VERTRES = 10,
        DESKTOPVERTRES = 117
    }
   
   
    public static double GetWindowsScreenScalingFactor(bool percentage = true)
    {
        //Create Graphics object from the current windows handle
        Graphics GraphicsObject = Graphics.FromHwnd(IntPtr.Zero);
        //Get Handle to the device context associated with this Graphics object
        IntPtr DeviceContextHandle = GraphicsObject.GetHdc();
        //Call GetDeviceCaps with the Handle to retrieve the Screen Height
        int LogicalScreenHeight = GetDeviceCaps(DeviceContextHandle, (int)DeviceCap.VERTRES);
        int PhysicalScreenHeight = GetDeviceCaps(DeviceContextHandle, (int)DeviceCap.DESKTOPVERTRES);
        //Divide the Screen Heights to get the scaling factor and round it to two decimals
        double ScreenScalingFactor = Math.Round(PhysicalScreenHeight / (double)LogicalScreenHeight, 2);
        //If requested as percentage - convert it
        if (percentage)
        {
            ScreenScalingFactor *= 100.0;
        }
        //Release the Handle and Dispose of the GraphicsObject object
        GraphicsObject.ReleaseHdc(DeviceContextHandle);
        GraphicsObject.Dispose();
        //Return the Scaling Factor
        return ScreenScalingFactor;
    }
   
    public static Size GetDisplayResolution()
    {
        var sf = GetWindowsScreenScalingFactor(false);
        var screenWidth = Screen.PrimaryScreen.Bounds.Width * sf;
        var screenHeight = Screen.PrimaryScreen.Bounds.Height * sf;
        return new Size((int)screenWidth, (int)screenHeight);
    }
   
    #endregion
   

to check display resolution

var size = GetDisplayResolution();
Console.WriteLine("Display Resoluton: " + size.Width + "x" + size.Height);

There seems to be some interest in Gavin's answer for which cortijon proposed a javascript version in the comments and iMalc provided a version with slightly fewer computations. Some have pointed out shortcomings with various code proposals and others have commented on the efficiency of some code proposals.

The algorithm provided by iMalc via Gavin's answer is the one that I am currently using in a javascript project and I just wanted to provide a cleaned up version here if it may help anyone.

// Some variables for reuse, others may do this differently
var p0x, p1x, p2x, p3x, ix,
    p0y, p1y, p2y, p3y, iy,
    collisionDetected;

// do stuff, call other functions, set endpoints...

// note: for my purpose I use |t| < |d| as opposed to
// |t| <= |d| which is equivalent to 0 <= t < 1 rather than
// 0 <= t <= 1 as in Gavin's answer - results may vary

var lineSegmentIntersection = function(){
    var d, dx1, dx2, dx3, dy1, dy2, dy3, s, t;

    dx1 = p1x - p0x;      dy1 = p1y - p0y;
    dx2 = p3x - p2x;      dy2 = p3y - p2y;
    dx3 = p0x - p2x;      dy3 = p0y - p2y;

    collisionDetected = 0;

    d = dx1 * dy2 - dx2 * dy1;

    if(d !== 0){
        s = dx1 * dy3 - dx3 * dy1;
        if((s <= 0 && d < 0 && s >= d) || (s >= 0 && d > 0 && s <= d)){
            t = dx2 * dy3 - dx3 * dy2;
            if((t <= 0 && d < 0 && t > d) || (t >= 0 && d > 0 && t < d)){
                t = t / d;
                collisionDetected = 1;
                ix = p0x + t * dx1;
                iy = p0y + t * dy1;
            }
        }
    }
};

On OSX 10.11, you can sudo nano /etc/paths and add the path(s) you want here, one per line. Way simpler than figuring which of ~/.bashrc, /etc/profile, '~/.bash_profile` etc... you should add to. Besides, why export and append $PATH to itself when you can just go and modify PATH directly...?

For Kotlin.

 notificationManager.notify(Calendar.getInstance().timeInMillis.toInt(),notificationBuilder.build())

Javascript now has a specific built in object called Map, you can call as follows :

   var myMap = new Map()

You can update it with .set :

   myMap.set("key0","value")

This has the advantage of methods you can use to handle look ups, like the boolean .has

  myMap.has("key1"); // evaluates to false 

You can use this before calling .get on your Map object to handle looking up non-existent keys

You can change the format too by doing this

string fecha = DateTime.Now.ToString(format:"dd-MM-yyyy");

// this change the "/" for the "-"

Are you explicitly setting the values as blank? For example:

<input type="text" name="textfield" value="">

That should stop browsers putting data in where it shouldn't. Alternatively, you can add the autocomplete attribute to the form tag:

<form autocomplete="off" ...></form>

Comprehension could be also convenient in this case:

# from a list
keys = ["k1", "k2"]
d = {k:None for k in keys}

# or from another dict
d1 = {"k1" : 1, "k2" : 2}
d2 = {k:None for k in d1.keys()}

d2
# {'k1': None, 'k2': None}

I'm not familiar with DB2, but have you tried COALESCE?

ie:

SELECT Product.ID, COALESCE(product.Name, "Internal") AS ProductName
FROM Product

Use ArrayList.set

list.set(2, "New");

DECLARE @uuid VARCHAR(50)
SET @uuid = 'a89b1acd95016ae6b9c8aabb07da2010'
SELECT  CAST(
        SUBSTRING(@uuid, 1, 8) + '-' + SUBSTRING(@uuid, 9, 4) + '-' + SUBSTRING(@uuid, 13, 4) + '-' +
        SUBSTRING(@uuid, 17, 4) + '-' + SUBSTRING(@uuid, 21, 12)
        AS UNIQUEIDENTIFIER)

>>> l = []
>>> l.__class__.__name__ in ('list', 'tuple')
True

JSON.stringify and JSON.parse are almost oposites, and "usually" this kind of thing will work:

var obj = ...;
var json = JSON.stringify(obj);  
var obj2 = JSON.parse(json);

so that obj and obj2 are "the same".

However there are some limitations to be aware of. Often these issues dont matter as you're dealing with simple objects. But I'll illustrate some of them here, using this helper function:

function jsonrepack( obj ) { return JSON.parse(JSON.stringify(obj) ); }

• You'll only get ownProperties of the object and lose prototypes:

  var MyClass = function() { this.foo="foo"; } 
  MyClass.prototype = { bar:"bar" }
  
  var o = new MyClass();
  var oo = jsonrepack(o);
  console.log(oo.bar); // undefined
  console.log( oo instanceof MyClass ); // false
  

• You'll lose identity:

  var o = {};
  var oo = jsonrepack(o);
  console.log( o === oo ); // false
  

• Functions dont survive:

  jsonrepack( { f:function(){} } ); // Returns {}
  

• Date objects end up as strings:

  jsonrepack(new Date(1990,2,1)); // Returns '1990-02-01T16:00:00.000Z'
  

• Undefined values dont survive:

  var v = { x:undefined }
  console.log("x" in v);              // true
  console.log("x" in jsonrepack(v));  // false
  

• Objects that provide a toJSON function may not behave correctly.

  x = { f:"foo", toJSON:function(){ return "EGAD"; } }
  jsonrepack(x) // Returns 'EGAD'
  

I'm sure there are issues with other built-in-types too. (All this was tested using node.js so you may get slightly different behaviour depending on your environment too).

When it does matter it can sometimes be overcome using the additional parameters of JSON.parse and JSON.stringify. For example:

function MyClass (v) {
   this.date = new Date(v.year,1,1);
   this.name = "an object";
};

MyClass.prototype.dance = function() {console.log("I'm dancing"); }

var o = new MyClass({year:2010});
var s = JSON.stringify(o);

// Smart unpack function
var o2 = JSON.parse( s, function(k,v){
  if(k==="") { 
     var rv = new MyClass(1990,0,0);
     rv.date = v.date;
     rv.name = v.name;
     return rv
  } else if(k==="date") {
    return new Date( Date.parse(v) );
  } else { return v; } } );

console.log(o);             // { date: <Mon Feb 01 2010 ...>, name: 'an object' }
console.log(o.constructor); // [Function: MyClass]
o.dance();                  // I'm dancing

console.log(o2);            // { date: <Mon Feb 01 2010 ...>, name: 'an object' }
console.log(o2.constructor) // [Function: MyClass]        
o2.dance();                 // I'm dancing

If you are using jQuery, use css to add CSS

$("#voltaic_holder").css({'position': 'absolute',
    'top': '-75px'});

To remove CSS attributes

$("#voltaic_holder").css({'position': '',
    'top': ''});

The solution to the problem is:

1. Find the .gitconfig file

2. [user] name = 1wQasdTeedFrsweXcs234saS56Scxs5423 email = [email protected] [credential] helper = osxkeychain [url ""] insteadOf = git:// [url "https://"] [url "https://"] insteadOf = git://

there would be a blank url="" replace it with url="https://"

[user]
    name = 1wQasdTeedFrsweXcs234saS56Scxs5423
    email = [email protected]
[credential]
    helper = osxkeychain
[url "https://"]
    insteadOf = git://
[url "https://"]
[url "https://"]
    insteadOf = git://

This will work :)

Happy Bower-ing

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

See this : What Python version can I use with Django?¶ https://docs.djangoproject.com/en/2.0/faq/install/

if you are using python27 you must to set django version :

try: $pip install django==1.9

There are several ways to do this. Both are very simple. Each of the examples works great. You can copy it into your project and test it.

The first method is preferable, the second is a bit outdated, but so far it works too.

Bootstrap 3 introduces responsive tables:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

Bootstrap 4 is similar, but with more control via some new classes:

...responsive across all viewports ... with .table-responsive. Or, pick a maximum breakpoint with which to have a responsive table up to by using .table-responsive{-sm|-md|-lg|-xl}.

Credit to Jason Bradley for providing an example:

You need add parameter errors='coerce' to function to_numeric:

ID = pd.to_numeric(ID, errors='coerce')

If ID is column:

df.ID = pd.to_numeric(df.ID, errors='coerce')

but non numeric are converted to NaN, so all values are float.

For int need convert NaN to some value e.g. 0 and then cast to int:

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)

Sample:

df = pd.DataFrame({'ID':['4806105017087','4806105017087','CN414149']})
print (df)
              ID
0  4806105017087
1  4806105017087
2       CN414149

print (pd.to_numeric(df.ID, errors='coerce'))
0    4.806105e+12
1    4.806105e+12
2             NaN
Name: ID, dtype: float64

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
print (df)
              ID
0  4806105017087
1  4806105017087
2              0

EDIT: If use pandas 0.25+ then is possible use integer_na:

df.ID = pd.to_numeric(df.ID, errors='coerce').astype('Int64')
print (df)
              ID
0  4806105017087
1  4806105017087
2            NaN

configuring working directories solved it for me, since I had multiple projects with own .eslintrc files openend in the same window.

Put this in your .vscode/settings.json

"eslint.workingDirectories": [
    "./backend", 
    "./frontend"
],

thanks to this guy on github: https://github.com/microsoft/vscode-eslint/issues/696#issuecomment-542592372

PS: useful command to list all subdirectories containing an .eslintrc except /node_modules:

find . .eslintrc | grep .eslintrc | grep -v node_modules

So, it seemed to be invoked when Spring container has started, if you want to do something at that time.

It just has one method to set the context, so you will get the context and do something to sth now already in context I think.

2. MonoReport

The suggested causes are now proven to be mostly impossible. I'm running SSMS V17.9.2 against SS 2014 and still have the problem. Memory problems have existed with this tool since at least 2006 when I started using SSMS.

Yes, MS 'wants' to get rid of diagramming but users won't let them. I have a feeling they will never fix any of these issues because they want users to be so fed up with the tool that enough of them quit using it and they can abandon it entirely.

Restarting is still a workaround if you can stand doing so numerous times per day.

Returns number of times the keyword is included in the string.

var count = "I have one keyword".match(/keyword/g);
var clean_count = !count ? false : count.length;

using $localStorage

app.controller('ProductController', function($scope, $localStorage) {
    $scope.setSelectedProduct = function(selectedObj){
        $localStorage.selectedObj= selectedObj;
    };
});

app.controller('CartController', function($scope,$localStorage) { 
    $scope.selectedProducts = $localStorage.selectedObj;
    $localStorage.$reset();//to remove
});

On click you can call method that invokes broadcast:

$rootScope.$broadcast('SOME_TAG', 'your value');

and the second controller will listen on this tag like:
$scope.$on('SOME_TAG', function(response) {
      // ....
})

using $rootScope:

window.sessionStorage.setItem("Mydata",data);
$scope.data = $window.sessionStorage.getItem("Mydata");

One way using angular service:

var app = angular.module("home", []);

app.controller('one', function($scope, ser1){
$scope.inputText = ser1;
});

app.controller('two',function($scope, ser1){
$scope.inputTextTwo = ser1;
});

app.factory('ser1', function(){
return {o: ''};
});

You can add one Section(with zero rows) above, then set the above sectionFooterView as current section's headerView, footerView doesn't float. Hope it gives a help.

You can use the standard evaluation version of mutate_each (which is mutate_each_) to change the column classes:

dat %>% mutate_each_(funs(factor), l1) %>% mutate_each_(funs(as.numeric), l2)

Copy the contents of /var/lib/mongodb to /data/db. The files you should be looking for should have names like your_db_name.ns and your_dbname.n where n is a number starting with 0. If you do not see such files under /var/lib/mongodb, search for them on your filesystem.

Once copied over, use --dbpath=/data/db when starting MongoDB via the mongod command.

In swift 5, I used following code to disable the textfield

override func viewDidLoad() {
   super.viewDidLoad()
   self.textfield.isEnabled = false
   //e.g
   self.design.isEnabled = false
}

Here is an answer based on that by Anubis (which is a better approach as it doesn't modify the headers for every request) but which is more equivalent to the code in the original question:

using Newtonsoft.Json;
...

var client = new HttpClient();
var httpRequestMessage = new HttpRequestMessage
    {
        Method = HttpMethod.Post,
        RequestUri = new Uri("https://api.clickatell.com/rest/message"),
        Headers = { 
            { HttpRequestHeader.Authorization.ToString(), "Bearer xxxxxxxxxxxxxxxxxxx" },
            { HttpRequestHeader.Accept.ToString(), "application/json" },
            { "X-Version", "1" }
        },
        Content = new StringContent(JsonConvert.SerializeObject(svm))
    };

var response = client.SendAsync(httpRequestMessage).Result;

Alternative answer, you can use this JDBC URL directly in your datasource configuration:

jdbc:mysql://yourserver:3306/yourdatabase?zeroDateTimeBehavior=convertToNull

Edit:

Source: MySQL Manual

Datetimes with all-zero components (0000-00-00 ...) — These values can not be represented reliably in Java. Connector/J 3.0.x always converted them to NULL when being read from a ResultSet.

Connector/J 3.1 throws an exception by default when these values are encountered as this is the most correct behavior according to the JDBC and SQL standards. This behavior can be modified using the zeroDateTimeBehavior configuration property. The allowable values are:

• exception (the default), which throws an SQLException with an SQLState of S1009.
• convertToNull, which returns NULL instead of the date.
• round, which rounds the date to the nearest closest value which is 0001-01-01.

Update: Alexander reported a bug affecting mysql-connector-5.1.15 on that feature. See CHANGELOGS on the official website.

It's also possible to use a regular expression to achieve this when you want to test for any whitespace character and not just a space.

var text = "sossjj ssskkk";
var regex = new Regex(@"\s");
regex.IsMatch(text); // true

Another alternative is KMP (Knuth–Morris–Pratt).

The KMP algorithm searches for a length-m substring in a length-n string in worst-case O(n+m) time, compared to a worst-case of O(n·m) for the naive algorithm, so using KMP may be reasonable if you care about worst-case time complexity.

Here's a JavaScript implementation by Project Nayuki, taken from https://www.nayuki.io/res/knuth-morris-pratt-string-matching/kmp-string-matcher.js:

// Searches for the given pattern string in the given text string using the Knuth-Morris-Pratt string matching algorithm.
// If the pattern is found, this returns the index of the start of the earliest match in 'text'. Otherwise -1 is returned.

function kmpSearch(pattern, text) {_x000D_
  if (pattern.length == 0)_x000D_
    return 0; // Immediate match_x000D_
_x000D_
  // Compute longest suffix-prefix table_x000D_
  var lsp = [0]; // Base case_x000D_
  for (var i = 1; i < pattern.length; i++) {_x000D_
    var j = lsp[i - 1]; // Start by assuming we're extending the previous LSP_x000D_
    while (j > 0 && pattern.charAt(i) != pattern.charAt(j))_x000D_
      j = lsp[j - 1];_x000D_
    if (pattern.charAt(i) == pattern.charAt(j))_x000D_
      j++;_x000D_
    lsp.push(j);_x000D_
  }_x000D_
_x000D_
  // Walk through text string_x000D_
  var j = 0; // Number of chars matched in pattern_x000D_
  for (var i = 0; i < text.length; i++) {_x000D_
    while (j > 0 && text.charAt(i) != pattern.charAt(j))_x000D_
      j = lsp[j - 1]; // Fall back in the pattern_x000D_
    if (text.charAt(i) == pattern.charAt(j)) {_x000D_
      j++; // Next char matched, increment position_x000D_
      if (j == pattern.length)_x000D_
        return i - (j - 1);_x000D_
    }_x000D_
  }_x000D_
  return -1; // Not found_x000D_
}_x000D_
_x000D_
console.log(kmpSearch('ays', 'haystack') != -1) // true_x000D_
console.log(kmpSearch('asdf', 'haystack') != -1) // false

Use delegate and event.target. delegate takes advantage of the event bubbling by letting one element listen for, and handle, events on child elements. target is the jQ-normalized property of the event object representing the object from which the event originated.

$(document).delegate('*', 'click', function (event) {
    // event.target is the element
    // $(event.target).text() gets its text
});

I found Sophos kept placing psexec.exe into the Quarantine section. Once I authorized it, it ran fine.

There are two problems in your code:

• The property is called visibility and not visiblity.
• It is not a property of the element itself but of its .style property.

It's easy to fix. Simple replace this:

document.getElementById("remember").visiblity

with this:

document.getElementById("remember").style.visibility

Really depends on your requirement, although lately I have seen a trend for classes with at least one bare constructor defined.

The upside of posting your parameters in via constructor is that you know those values can be relied on after instantiation. The downside is that you'll need to put more work in with any library that expects to be able to create objects with a bare constructor.

My personal preference is to go with a bare constructor and set any properties as part of the declaration.

Person p=new Person()
{
   Name = "Han Solo",
   Age = 39
};

This gets around the "class lacks bare constructor" problem, plus reduces maintenance ( I can set more things without changing the constructor ).

typeof parseInt("123") => number
typeof Number("123") => number
typeof new Number("123") => object (Number primitive wrapper object)

first two will give you better performance as it returns a primitive instead of an object.

I used String.prototype.match(regex) which returns a string array of all found matches of the given regex in the string (more info see here):

function getLastIndex(text, regex, limit = text.length) {_x000D_
  const matches = text.match(regex);_x000D_
_x000D_
  // no matches found_x000D_
  if (!matches) {_x000D_
    return -1;_x000D_
  }_x000D_
_x000D_
  // matches found but first index greater than limit_x000D_
  if (text.indexOf(matches[0] + matches[0].length) > limit) {_x000D_
    return -1;_x000D_
  }_x000D_
_x000D_
  // reduce index until smaller than limit_x000D_
  let i = matches.length - 1;_x000D_
  let index = text.lastIndexOf(matches[i]);_x000D_
  while (index > limit && i >= 0) {_x000D_
    i--;_x000D_
    index = text.lastIndexOf(matches[i]);_x000D_
  }_x000D_
  return index > limit ? -1 : index;_x000D_
}_x000D_
_x000D_
// expect -1 as first index === 14_x000D_
console.log(getLastIndex('First Sentence. Last Sentence. Unfinished', /\. /g, 10));_x000D_
_x000D_
// expect 29_x000D_
console.log(getLastIndex('First Sentence. Last Sentence. Unfinished', /\. /g));

You can use GAS, which is gcc's backend assembler:

If you are using Bootstrap 3.x, you can now change the color with the new @input-border-focus variable.

See the commit for more info and warnings.

In _variables.scss update @input-border-focus.

To modify the size/other parts of this glow modify the mixins/_forms.scss

@mixin form-control-focus($color: $input-border-focus) {
  $color-rgba: rgba(red($color), green($color), blue($color), .6);
  &:focus {
    border-color: $color;
    outline: 0;
    @include box-shadow(inset 0 1px 1px rgba(0,0,0,.075), 0 0 4px $color-rgba);
  }
}

Check out this plunkr.

When you're binding to variables, you need to use the brackets. Also, you use the hashtag when you want to get references to elements in your html, not for declaring variables inside of templates like that.

<md-button-toggle *ngFor="let indicador of indicadores; let first = first;" [value]="indicador.id" [checked]="first"> 
...

Edit: Thanks to Christopher Moore: Angular exposes the following local variables:

• index
• first
• last
• even
• odd

You probably have allProviders typed as object[] as well. And property country does not exist on object. If you don't care about typing, you can declare both allProviders and countryProviders as Array<any>:

let countryProviders: Array<any>;
let allProviders: Array<any>;

If you do want static type checking. You can create an interface for the structure and use it:

interface Provider {
    region: string,
    country: string,
    locale: string,
    company: string
}

let countryProviders: Array<Provider>;
let allProviders: Array<Provider>;

Something like?

select t.*, round(dbms_random.value() * 8) + 1 from foo t;

Edit: David has pointed out this gives uneven distribution for 1 and 9.

As he points out, the following gives a better distribution:

select t.*, floor(dbms_random.value(1, 10)) from foo t;

Thanks Jason Rogers's answer first.

In Android && cpp should be this:

const char *nativeString = env->GetStringUTFChars(javaString, nullptr);

// use your string

env->ReleaseStringUTFChars(javaString, nativeString);

Can fix this errors:

1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'

2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'

3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'

4.add "env->DeleteLocalRef(nativeString);" at end.

Yes, we have a way to get screenshot extension of .png using python webdriver

use below code if you working in python webriver.it is very simple.

driver.save_screenshot('D\folder\filename.png')

Using some of the above recommendations, the following function and code is working for search a date range:

Set date with the time component set to 00:00:00

public static DateTime GetDateZeroTime(DateTime date)
{
    return new DateTime(date.Year, date.Month, date.Day, 0, 0, 0);
}

Usage

var modifieddatebegin = Tools.Utilities.GetDateZeroTime(form.modifieddatebegin);

var modifieddateend = Tools.Utilities.GetDateZeroTime(form.modifieddateend.AddDays(1));

As in the answer of Escobar Ceaser, I suggest to use quotes arround the whole path. It's the common way to wrap the whole path in "", not only separate directory names within the path.

I had a similar issue that it didn't work for me. But it was no option to use "" within the path for separate directory names because the path contained environment variables, which theirself cover more than one directory hierarchies. The conclusion was that I missed the space between the closing " and the (

The correct version, with the space before the bracket, would be

If NOT exist "C:\Documents and Settings\John\Start Menu\Programs\Software Folder" (
 start "\\filer\repo\lab\software\myapp\setup.exe"
 pause
) 

This is how I usually do it (sql server).

Create Table Master (
MasterID int identity(1,1) primary key,
Stuff varchar(10)
)
GO
Create Table Detail (
DetailID int identity(1,1) primary key,
MasterID int references Master, --use 'references'
Stuff varchar(10))
GO
Insert into Master values('value')
--(1 row(s) affected)
GO
Insert into Detail values (1, 'Value1') -- Works
--(1 row(s) affected)
insert into Detail values (2, 'Value2') -- Fails
--Msg 547, Level 16, State 0, Line 2
--The INSERT statement conflicted with the FOREIGN KEY constraint "FK__Detail__MasterID__0C70CFB4". 
--The conflict occurred in database "Play", table "dbo.Master", column 'MasterID'.
--The statement has been terminated.

As you can see the second insert into the detail fails because of the foreign key. Here's a good weblink that shows various syntax for defining FK during table creation or after.

http://www.1keydata.com/sql/sql-foreign-key.html

The for loop is definitely more pythonic, as it uses Python's higher level built in functionality to convey what you're doing both more clearly and concisely. The overhead of range vs xrange, and assigning an unused i variable, stem from the absence of a statement like Verilog's repeat statement. The main reason to stick to the for range solution is that other ways are more complex. For instance:

from itertools import repeat

for unused in repeat(None, 10):
    del unused   # redundant and inefficient, the name is clear enough
    print "This is run 10 times"

Using repeat instead of range here is less clear because it's not as well known a function, and more complex because you need to import it. The main style guides if you need a reference are PEP 20 - The Zen of Python and PEP 8 - Style Guide for Python Code.

We also note that the for range version is an explicit example used in both the language reference and tutorial, although in that case the value is used. It does mean the form is bound to be more familiar than the while expansion of a C-style for loop.

You can also rest your string and work with it like an array of elements using

• Array.prototype.filter()

const mainStr = 'str1,str2,str3,str4';_x000D_
const commas = [...mainStr].filter(l => l === ',').length;_x000D_
_x000D_
console.log(commas);

Or

• Array.prototype.reduce()

const mainStr = 'str1,str2,str3,str4';_x000D_
const commas = [...mainStr].reduce((a, c) => c === ',' ? ++a : a, 0);_x000D_
_x000D_
console.log(commas);

The easiest solution is to toggleClass() both classes individually.

Let's say you have an icon:

    <i id="target" class="fa fa-angle-down"></i>

To toggle between fa-angle-down and fa-angle-up do the following:

    $('.sometrigger').click(function(){
        $('#target').toggleClass('fa-angle-down');
        $('#target').toggleClass('fa-angle-up');
    });

Since we had fa-angle-down at the beginning without fa-angle-up each time you toggle both, one leaves for the other to appear.

Errors you'll see if a RestTemplate isn't defined

Consider defining a bean of type 'org.springframework.web.client.RestTemplate' in your configuration.

or

No qualifying bean of type [org.springframework.web.client.RestTemplate] found

How to define a RestTemplate via annotations

Depending on which technologies you're using and what versions will influence how you define a RestTemplate in your @Configuration class.

Spring >= 4 without Spring Boot

Simply define an @Bean:

@Bean
public RestTemplate restTemplate() {
    return new RestTemplate();
}

Spring Boot <= 1.3

No need to define one, Spring Boot automatically defines one for you.

Spring Boot >= 1.4

Spring Boot no longer automatically defines a RestTemplate but instead defines a RestTemplateBuilder allowing you more control over the RestTemplate that gets created. You can inject the RestTemplateBuilder as an argument in your @Bean method to create a RestTemplate:

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
   // Do any additional configuration here
   return builder.build();
}

Using it in your class

@Autowired
private RestTemplate restTemplate;

or

@Inject
private RestTemplate restTemplate;

If you are using Spring framework in your project you can also use:

org.springframework.util.StringUtils.parseLocaleString("en_US");

Documentation:

Parse the given String representation into a Locale

.any() and .all() are great for the extreme cases, but not when you're looking for a specific number of null values. Here's an extremely simple way to do what I believe you're asking. It's pretty verbose, but functional.

import pandas as pd
import numpy as np

# Some test data frame
df = pd.DataFrame({'num_legs':          [2, 4,      np.nan, 0, np.nan],
                   'num_wings':         [2, 0,      np.nan, 0, 9],
                   'num_specimen_seen': [10, np.nan, 1,     8, np.nan]})

# Helper : Gets NaNs for some row
def row_nan_sums(df):
    sums = []
    for row in df.values:
        sum = 0
        for el in row:
            if el != el: # np.nan is never equal to itself. This is "hacky", but complete.
                sum+=1
        sums.append(sum)
    return sums

# Returns a list of indices for rows with k+ NaNs
def query_k_plus_sums(df, k):
    sums = row_nan_sums(df)
    indices = []
    i = 0
    for sum in sums:
        if (sum >= k):
            indices.append(i)
        i += 1
    return indices

# test
print(df)
print(query_k_plus_sums(df, 2))

Output

   num_legs  num_wings  num_specimen_seen
0       2.0        2.0               10.0
1       4.0        0.0                NaN
2       NaN        NaN                1.0
3       0.0        0.0                8.0
4       NaN        9.0                NaN
[2, 4]

Then, if you're like me and want to clear those rows out, you just write this:

# drop the rows from the data frame
df.drop(query_k_plus_sums(df, 2),inplace=True)
# Reshuffle up data (if you don't do this, the indices won't reset)
df = df.sample(frac=1).reset_index(drop=True)
# print data frame
print(df)

Output:

   num_legs  num_wings  num_specimen_seen
0       4.0        0.0                NaN
1       0.0        0.0                8.0
2       2.0        2.0               10.0

You can use:

select to_date(to_char(date_field,'dd/mm/yyyy')) from table

$i=0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
if($i>0){
    $import="INSERT into importing(text,number)values('".$data[0]."','".$data[1]."')";
    mysql_query($import) or die(mysql_error());
}
$i=1;
}

Simple Steps:

1. Click File > Project Structure

2. Click Dependencies > Find and Click org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.21 (or whatever your current version is)

3. Under Details > update section, click [update variable][update dependencies]

4. Click Ok

the $.Browser.msie is not on the latest JQuery anymore... you have to use the $.support

like below:

 <script>

     (function ($) {
         $.support.placeholder = ('placeholder' in document.createElement('input'));
     })(jQuery);


     //fix for IE7 and IE8
     $(function () {
         if (!$.support.placeholder) {
             $("[placeholder]").focus(function () {
                 if ($(this).val() == $(this).attr("placeholder")) $(this).val("");
             }).blur(function () {
                 if ($(this).val() == "") $(this).val($(this).attr("placeholder"));
             }).blur();

             $("[placeholder]").parents("form").submit(function () {
                 $(this).find('[placeholder]').each(function() {
                     if ($(this).val() == $(this).attr("placeholder")) {
                         $(this).val("");
                     }
                 });
             });
         }
     });
 </script>

How about:

df.insert(0, 'mean', df.mean(1))

A poor man's option is to use the tool tig¹ on HEAD, search for the commit, and then visually follow the line from that commit back up until a merge commit is seen. The default merge message should specify what branch is getting merged to where :)

¹ Tig is an ncurses-based text-mode interface for Git. It functions mainly as a Git repository browser, but it can also assist in staging changes for commit at chunk level and act as a pager for output from various Git commands.

You can use below script for reading child of the above xml. It will work with IE and Mozila Firefox both.

<script type="text/javascript">

function readXml(xmlFile){

var xmlDoc;

if(typeof window.DOMParser != "undefined") {
    xmlhttp=new XMLHttpRequest();
    xmlhttp.open("GET",xmlFile,false);
    if (xmlhttp.overrideMimeType){
        xmlhttp.overrideMimeType('text/xml');
    }
    xmlhttp.send();
    xmlDoc=xmlhttp.responseXML;
}
else{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async="false";
    xmlDoc.load(xmlFile);
}
var tagObj=xmlDoc.getElementsByTagName("marker");
var typeValue = tagObj[0].getElementsByTagName("type")[0].childNodes[0].nodeValue;
var titleValue = tagObj[0].getElementsByTagName("title")[0].childNodes[0].nodeValue;
}
</script>

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, and it introduces other dangers:

• Use Caution with SQL Server's MERGE Statement

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

BEGIN TRANSACTION;

UPDATE dbo.table WITH (UPDLOCK, SERIALIZABLE) 
  SET ... WHERE PK = @PK;

IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END

COMMIT TRANSACTION;

• Please stop using this UPSERT anti-pattern

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;

BEGIN TRANSACTION;

IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• Checking for potential constraint violations before entering TRY/CATCH
• Performance impact of different error handling techniques

You have to use RegExp object if your pattern is string

var xxx = "victoria";
var yyy = "i";
var rgxp = new RegExp(yyy, "g");
alert(xxx.match(rgxp).length);

If pattern is not dynamic string:

var xxx = "victoria";
var yyy = /i/g;
alert(xxx.match(yyy).length);

Here's my PowerShell Send-MailMessage sample for Gmail...

Tested and working solution:

$EmailFrom = "[email protected]"
$EmailTo = "[email protected]"
$Subject = "Notification from XYZ"
$Body = "this is a notification from XYZ Notifications.."
$SMTPServer = "smtp.gmail.com"
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("username", "password");
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body)

Just change $EmailTo, and username/password in $SMTPClient.Credentials... Do not include @gmail.com in your username...

First Step:-

Select Project Target -> Build Setting -> Search('Define') -> Define Module update value No to Yes

"Defines Module": YES.

"Always Embed Swift Standard Libraries" : YES.

"Install Objective-C Compatibility Header" : YES.

Second Step:-

Add Swift file Class in Objective C ".h" File as below

#import <UIKit/UIKit.h>

@class TestViewController(Swift File);

@interface TestViewController(Objective C File) : UIViewController

@end

Import 'ProjectName(Your Project Name)-Swift.h' in Objective C ".m" file

//TestViewController.m 
#import "TestViewController.h"

/*import ProjectName-Swift.h file to access Swift file here*/

#import "ProjectName-Swift.h"

I'm more used to the subquery solution to this, but I have not tried it in MySQL:

DELETE  FROM posts
WHERE   project_id IN (
            SELECT  project_id
            FROM    projects
            WHERE   client_id = :client_id
        );

I merely use unsigned BIGINT while storing UTC ...

which then still can be adjusted to local time in PHP.

the DATETIME to be selected with FROM_UNIXTIME( integer_timestamp_column ).

one obviously should set an index on that column, else there would be no advance.

Try the following:

foo(*values)

This can be found in the Python docs as Unpacking Argument Lists.

Here is also a good and simple site to check your php codes and share your code with fiends :

eval isn't always evil. There are times where it's perfectly appropriate.

However, eval is currently and historically massively over-used by people who don't know what they're doing. That includes people writing JavaScript tutorials, unfortunately, and in some cases this can indeed have security consequences - or, more often, simple bugs. So the more we can do to throw a question mark over eval, the better. Any time you use eval you need to sanity-check what you're doing, because chances are you could be doing it a better, safer, cleaner way.

To give an all-too-typical example, to set the colour of an element with an id stored in the variable 'potato':

eval('document.' + potato + '.style.color = "red"');

If the authors of the kind of code above had a clue about the basics of how JavaScript objects work, they'd have realised that square brackets can be used instead of literal dot-names, obviating the need for eval:

document[potato].style.color = 'red';

...which is much easier to read as well as less potentially buggy.

(But then, someone who /really/ knew what they were doing would say:

document.getElementById(potato).style.color = 'red';

which is more reliable than the dodgy old trick of accessing DOM elements straight out of the document object.)

Here's a tricky way to do this - select the cells that you want to replace and in Excel 2010 select F5 to bring up the "goto" box. Hit the "special" button. Select "blanks" - this should select all the cells that are blank. Enter NULL or whatever you want in the formula box and hit ctrl + enter to apply to all selected cells. Easy!

You have most of the code…

CURLOPT_HTTPHEADER for curl_setopt() takes an array with each header as an element. You have one element with multiple headers.

You also need to add the Authorization header to your $header array.

$header = array();
$header[] = 'Content-length: 0';
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: OAuth SomeHugeOAuthaccess_tokenThatIReceivedAsAString';

Composition to the rescue!

Given the reason, rather than invoking actions across controllers one should design controllers to seperate shared and custom parts of the code. This will help to avoid both - code duplication and breaking MVC pattern.

Although that can be done in a number of ways, using concerns (composition) is a good practice.

# controllers/a_controller.rb
class AController < ApplicationController
  include Createable

  private def redirect_url
    'one/url'
  end
end

# controllers/b_controller.rb
class BController < ApplicationController
  include Createable

  private def redirect_url
    'another/url'
  end
end

# controllers/concerns/createable.rb
module Createable
  def create
    do_usefull_things
    redirect_to redirect_url
  end
end

Hope that helps.

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

In your HTML code

<form [formGroup]="userForm">
    <input type="text" class="form-control"  [value]="item.UserFirstName" formControlName="UserFirstName">
    <input type="text" class="form-control"  [value]="item.UserLastName" formControlName="UserLastName">
</form>

In your Typescript code

export class UserprofileComponent implements OnInit {
    userForm: FormGroup;
    constructor(){ 
       this.userForm = new FormGroup({
          UserFirstName: new FormControl(),
          UserLastName: new FormControl()
       });
    }
}

This works perfectly, it does not give any error.

Abstraction is about identifying commonalities and reducing features that you have to work with at different levels of your code.

e.g. I may have a Vehicle class. A Car would derive from a Vehicle, as would a Motorbike. I can ask each Vehicle for the number of wheels, passengers etc. and that info has been abstracted and identified as common from Cars and Motorbikes.

In my code I can often just deal with Vehicles via common methods go(), stop() etc. When I add a new Vehicle type later (e.g. Scooter) the majority of my code would remain oblivious to this fact, and the implementation of Scooter alone worries about Scooter particularities.

Personally, I like this much better (which, granted, is just a different way of writing the currently selected "best answer"):

money = float(1234.5)
print('$' + format(money, ',.2f'))

Or, if you REALLY don't like "adding" multiple strings to combine them, you could do this instead:

money = float(1234.5)
print('${0}'.format(format(money, ',.2f')))

I just think both of these styles are a bit easier to read. :-)

(of course, you can still incorporate an If-Else to handle negative values as Eric suggests too)

If you want to avoid adding extra dependencies, I found node's process.argv to be useful:

gulp.task('mytask', function() {
    console.log(process.argv);
});

So the following:

gulp mytask --option 123

should display:

[ 'node', 'path/to/gulp.js', 'mytask', '--option', '123']

If you are sure that the desired parameter is in the right position, then the flags aren't needed.** Just use (in this case):

var option = process.argv[4]; //set to '123'

BUT: as the option may not be set, or may be in a different position, I feel that a better idea would be something like:

var option, i = process.argv.indexOf("--option");
if(i>-1) {
    option = process.argv[i+1];
}

That way, you can handle variations in multiple options, like:

//task should still find 'option' variable in all cases
gulp mytask --newoption somestuff --option 123
gulp mytask --option 123 --newoption somestuff
gulp mytask --flag --option 123

** Edit: true for node scripts, but gulp interprets anything without a leading "--" as another task name. So using gulp mytask 123 will fail because gulp can't find a task called '123'.

You are returning a reference to ret which is a variable on the stack.

Here's a Prototype version of resizing a text area that is not dependent on the number of columns in the textarea. This is a superior technique because it allows you to control the text area via CSS as well as have variable width textarea. Additionally, this version displays the number of characters remaining. While not requested, it's a pretty useful feature and is easily removed if unwanted.

//inspired by: http://github.com/jaz303/jquery-grab-bag/blob/63d7e445b09698272b2923cb081878fd145b5e3d/javascripts/jquery.autogrow-textarea.js
if (window.Widget == undefined) window.Widget = {}; 

Widget.Textarea = Class.create({
  initialize: function(textarea, options)
  {
    this.textarea = $(textarea);
    this.options = $H({
      'min_height' : 30,
      'max_length' : 400
    }).update(options);

    this.textarea.observe('keyup', this.refresh.bind(this));

    this._shadow = new Element('div').setStyle({
      lineHeight : this.textarea.getStyle('lineHeight'),
      fontSize : this.textarea.getStyle('fontSize'),
      fontFamily : this.textarea.getStyle('fontFamily'),
      position : 'absolute',
      top: '-10000px',
      left: '-10000px',
      width: this.textarea.getWidth() + 'px'
    });
    this.textarea.insert({ after: this._shadow });

    this._remainingCharacters = new Element('p').addClassName('remainingCharacters');
    this.textarea.insert({after: this._remainingCharacters});  
    this.refresh();  
  },

  refresh: function()
  { 
    this._shadow.update($F(this.textarea).replace(/\n/g, '<br/>'));
    this.textarea.setStyle({
      height: Math.max(parseInt(this._shadow.getHeight()) + parseInt(this.textarea.getStyle('lineHeight').replace('px', '')), this.options.get('min_height')) + 'px'
    });

    var remaining = this.options.get('max_length') - $F(this.textarea).length;
    this._remainingCharacters.update(Math.abs(remaining)  + ' characters ' + (remaining > 0 ? 'remaining' : 'over the limit'));
  }
});

Create the widget by calling new Widget.Textarea('element_id'). The default options can be overridden by passing them as an object, e.g. new Widget.Textarea('element_id', { max_length: 600, min_height: 50}). If you want to create it for all textareas on the page, do something like:

Event.observe(window, 'load', function() {
  $$('textarea').each(function(textarea) {
    new Widget.Textarea(textarea);
  });   
});

This may not be the best way for MVC ( https://stackoverflow.com/a/9461386/5869805 )

Below is how you render a view in Application_Error and write it to http response. You do not need to use redirect. This will prevent a second request to server, so the link in browser's address bar will stay same. This may be good or bad, it depends on what you want.

Global.asax.cs

protected void Application_Error()
{
    var exception = Server.GetLastError();
    // TODO do whatever you want with exception, such as logging, set errorMessage, etc.
    var errorMessage = "SOME FRIENDLY MESSAGE";

    // TODO: UPDATE BELOW FOUR PARAMETERS ACCORDING TO YOUR ERROR HANDLING ACTION
    var errorArea = "AREA";
    var errorController = "CONTROLLER";
    var errorAction = "ACTION";
    var pathToViewFile = $"~/Areas/{errorArea}/Views/{errorController}/{errorAction}.cshtml"; // THIS SHOULD BE THE PATH IN FILESYSTEM RELATIVE TO WHERE YOUR CSPROJ FILE IS!

    var requestControllerName = Convert.ToString(HttpContext.Current.Request.RequestContext?.RouteData?.Values["controller"]);
    var requestActionName = Convert.ToString(HttpContext.Current.Request.RequestContext?.RouteData?.Values["action"]);

    var controller = new BaseController(); // REPLACE THIS WITH YOUR BASE CONTROLLER CLASS
    var routeData = new RouteData { DataTokens = { { "area", errorArea } }, Values = { { "controller", errorController }, {"action", errorAction} } };
    var controllerContext = new ControllerContext(new HttpContextWrapper(HttpContext.Current), routeData, controller);
    controller.ControllerContext = controllerContext;

    var sw = new StringWriter();
    var razorView = new RazorView(controller.ControllerContext, pathToViewFile, "", false, null);
    var model = new ViewDataDictionary(new HandleErrorInfo(exception, requestControllerName, requestActionName));
    var viewContext = new ViewContext(controller.ControllerContext, razorView, model, new TempDataDictionary(), sw);
    viewContext.ViewBag.ErrorMessage = errorMessage;
    //TODO: add to ViewBag what you need
    razorView.Render(viewContext, sw);
    HttpContext.Current.Response.Write(sw);
    Server.ClearError();
    HttpContext.Current.Response.End(); // No more processing needed (ex: by default controller/action routing), flush the response out and raise EndRequest event.
}

View

@model HandleErrorInfo
@{
    ViewBag.Title = "Error";
    // TODO: SET YOUR LAYOUT
}
<div class="">
    ViewBag.ErrorMessage
</div>
@if(Model != null && HttpContext.Current.IsDebuggingEnabled)
{
    <div class="" style="background:khaki">

Have been trying every variation on João's solution to get an IN List query to work with Tornado's mysql wrapper, and was still getting the accursed "TypeError: not enough arguments for format string" error. Turns out adding "*" to the list var "*args" did the trick.

args=['A', 'C']
sql='SELECT fooid FROM foo WHERE bar IN (%s)'
in_p=', '.join(list(map(lambda x: '%s', args)))
sql = sql % in_p
db.query(sql, *args)

TL;DR

SELECT json_agg(t) FROM t

for a JSON array of objects, and

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

for a JSON object of arrays.

List of objects

This section describes how to generate a JSON array of objects, with each row being converted to a single object. The result looks like this:

[{"a":1,"b":"value1"},{"a":2,"b":"value2"},{"a":3,"b":"value3"}]

9.3 and up

The json_agg function produces this result out of the box. It automatically figures out how to convert its input into JSON and aggregates it into an array.

SELECT json_agg(t) FROM t

There is no jsonb (introduced in 9.4) version of json_agg. You can either aggregate the rows into an array and then convert them:

SELECT to_jsonb(array_agg(t)) FROM t

or combine json_agg with a cast:

SELECT json_agg(t)::jsonb FROM t

My testing suggests that aggregating them into an array first is a little faster. I suspect that this is because the cast has to parse the entire JSON result.

9.2

9.2 does not have the json_agg or to_json functions, so you need to use the older array_to_json:

SELECT array_to_json(array_agg(t)) FROM t

You can optionally include a row_to_json call in the query:

SELECT array_to_json(array_agg(row_to_json(t))) FROM t

This converts each row to a JSON object, aggregates the JSON objects as an array, and then converts the array to a JSON array.

I wasn't able to discern any significant performance difference between the two.

Object of lists

This section describes how to generate a JSON object, with each key being a column in the table and each value being an array of the values of the column. It's the result that looks like this:

{"a":[1,2,3], "b":["value1","value2","value3"]}

9.5 and up

We can leverage the json_build_object function:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

You can also aggregate the columns, creating a single row, and then convert that into an object:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

Note that aliasing the arrays is absolutely required to ensure that the object has the desired names.

Which one is clearer is a matter of opinion. If using the json_build_object function, I highly recommend putting one key/value pair on a line to improve readability.

You could also use array_agg in place of json_agg, but my testing indicates that json_agg is slightly faster.

There is no jsonb version of the json_build_object function. You can aggregate into a single row and convert:

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Unlike the other queries for this kind of result, array_agg seems to be a little faster when using to_jsonb. I suspect this is due to overhead parsing and validating the JSON result of json_agg.

Or you can use an explicit cast:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )::jsonb
FROM t

The to_jsonb version allows you to avoid the cast and is faster, according to my testing; again, I suspect this is due to overhead of parsing and validating the result.

9.4 and 9.3

The json_build_object function was new to 9.5, so you have to aggregate and convert to an object in previous versions:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

or

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

depending on whether you want json or jsonb.

(9.3 does not have jsonb.)

9.2

In 9.2, not even to_json exists. You must use row_to_json:

SELECT row_to_json(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Documentation

Find the documentation for the JSON functions in JSON functions.

json_agg is on the aggregate functions page.

Design

If performance is important, ensure you benchmark your queries against your own schema and data, rather than trust my testing.

Whether it's a good design or not really depends on your specific application. In terms of maintainability, I don't see any particular problem. It simplifies your app code and means there's less to maintain in that portion of the app. If PG can give you exactly the result you need out of the box, the only reason I can think of to not use it would be performance considerations. Don't reinvent the wheel and all.

Nulls

Aggregate functions typically give back NULL when they operate over zero rows. If this is a possibility, you might want to use COALESCE to avoid them. A couple of examples:

SELECT COALESCE(json_agg(t), '[]'::json) FROM t

Or

SELECT to_jsonb(COALESCE(array_agg(t), ARRAY[]::t[])) FROM t

_{Credit to Hannes Landeholm for pointing this out}

They are equivalent. See this code:

mySlice1 := make([]int, 0)
mySlice2 := []int{}
fmt.Println("mySlice1", cap(mySlice1))
fmt.Println("mySlice2", cap(mySlice2))

Output:

mySlice1 0
mySlice2 0

Both slices have 0 capacity which implies both slices have 0 length (cannot be greater than the capacity) which implies both slices have no elements. This means the 2 slices are identical in every aspect.

Take a look at the Packages documentation (Section 6.4) here: http://docs.python.org/tutorial/modules.html

In short, you need to put a blank file named

__init__.py

in the "lib" directory.

It looks like you're using python 3.x. In python3, filter, map, zip, etc return an object which is iterable, but not a list. In other words,

filter(func,data) #python 2.x

is equivalent to:

list(filter(func,data)) #python 3.x

I think it was changed because you (often) want to do the filtering in a lazy sense -- You don't need to consume all of the memory to create a list up front, as long as the iterator returns the same thing a list would during iteration.

If you're familiar with list comprehensions and generator expressions, the above filter is now (almost) equivalent to the following in python3.x:

( x for x in data if func(x) ) 

As opposed to:

[ x for x in data if func(x) ]

in python 2.x

The following will only work if you do not have spaces in your input:

xargs -L 1
xargs --max-lines=1 # synonym for the -L option

from the man page:

-L max-lines
          Use at most max-lines nonblank input lines per command line.
          Trailing blanks cause an input line to be logically continued  on
          the next input line.  Implies -x.

Use Sessions.

Page1:

session_start();
$_SESSION['message'] = "Some message"

Page2:

session_start();
var_dump($_SESSION['message']);

You can use the auto_now and auto_now_add options for updated_at and created_at respectively.

class MyModel(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

Here is an example code that you may use:

$ STR="String;1;2;3"
$ for EACH in `echo "$STR" | grep -o -e "[^;]*"`; do
    echo "Found: \"$EACH\"";
done

grep -o -e "[^;]*" will select anything that is not ';', therefore spliting the string by ';'.

Hope that help.

Why don't you examine System.getProperty("os.arch") value in your code?

If you want to know the list of procedures you can run the following command -

show procedure status;

It will give you the list of procedures and their definers Then you can run the show create procedure <procedurename>;

Put double exclamation mark i.e !! before the function name that you want to check. If it exists, it will return true.

function abc(){
}
!!window.abc; // return true
!!window.abcd; // return false

My solution, in case you have a TextView as each row of the spinner:

    // TODO: add a fake item as the last one of "items"
    final ArrayAdapter<String> adapter=new ArrayAdapter<String>(..,..,items) 
      {
      @Override
      public View getDropDownView(final int position,final View convertView,final ViewGroup parent)
        {
        final View dropDownView=super.getDropDownView(position,convertView,parent);
        ((TextView)dropDownView.findViewById(android.R.id.text1)).setHeight(position==getCount()-1?0:getDimensionFromAttribute(..,R.attr.dropdownListPreferredItemHeight));
        dropDownView.getLayoutParams().height=position==getCount()-1?0:LayoutParams.MATCH_PARENT;
        return dropDownView;
        }
      }

    ...
    spinner.setAdapter(adapter);
    _actionModeSpinnerView.setSelection(dataAdapter.getCount()-1,false);



  public static int getDimensionFromAttribute(final Context context,final int attr)
    {
    final TypedValue typedValue=new TypedValue();
    if(context.getTheme().resolveAttribute(attr,typedValue,true))
      return TypedValue.complexToDimensionPixelSize(typedValue.data,context.getResources().getDisplayMetrics());
    return 0;

Actually ngAfterViewInit() will initiate only once when the component initiate.

If you really want a event triggers after the HTML element renter on the screen then you can use ngAfterViewChecked()

There is always intval() - Not sure if this is what you were looking for...

example: -

$floatValue = 4.5;
echo intval($floatValue);    // Returns 4

It won't round off the value to an integer, but will strip out the decimal and trailing digits, and return the integer before the decimal.

Here is some documentation for this: - http://php.net/manual/en/function.intval.php

Given that ECMA is a 'class-free' language, implementing classical composition doesn't - in my eyes - make a lot of sense. The danger is that, in so doing, you are effectively attempting to re-engineer the language (and, if one feels strongly about that, there are excellent holistic solutions such as the aforementioned TypeScript that mitigate reinventing the wheel)

Now that isn't to say that composition is out of the question however in Plain Old JS. I researched this at length some time ago. The strongest candidate I have seen for handling composition within the object prototypal paradigm is stampit, which I now use across a wide range of projects. And, importantly, it adheres to a well articulated specification.

Your array.xml is not right. change it to like this

Here is array.xml file

<?xml version="1.0" encoding="utf-8"?>  
<resources>  
    <string-array name="testArray">  
        <item>first</item>  
        <item>second</item>  
        <item>third</item>  
        <item>fourth</item>  
        <item>fifth</item>  
   </string-array>
</resources>

Just check the packaging, the simplest answer I can provide is that your package has been mislabeled (within a class).

Also, you may have some weird characters. Try white-flushing the code in a Notepad (or Gedit) and then pasting it into a newly created class with your IDE.

Figured it out, folks! for the NAME of the text box, you have to use "q". I had "g" just for my own personal preferences. But apparently it has to be "q".

Anyone know why?

There are plenty of good solutions in here, but as none of then check if the path is rooted in an existing drive here's another one:

private bool IsValidPath(string path)
{
    // Check if the path is rooted in a driver
    if (path.Length < 3) return false;
    Regex driveCheck = new Regex(@"^[a-zA-Z]:\\$");
    if (!driveCheck.IsMatch(path.Substring(0, 3))) return false;

    // Check if such driver exists
    IEnumerable<string> allMachineDrivers = DriveInfo.GetDrives().Select(drive => drive.Name);
    if (!allMachineDrivers.Contains(path.Substring(0, 3))) return false;

    // Check if the rest of the path is valid
    string InvalidFileNameChars = new string(Path.GetInvalidPathChars());
    InvalidFileNameChars += @":/?*" + "\"";
    Regex containsABadCharacter = new Regex("[" + Regex.Escape(InvalidFileNameChars) + "]");
    if (containsABadCharacter.IsMatch(path.Substring(3, path.Length - 3)))
        return false;
    if (path[path.Length - 1] == '.') return false;

    return true;
}

This solution does not take relative paths into account.

All the information can be found in a PG_TABLE_DEF table, documentation.

Listing all tables in a public schema (default) - show tables equivalent:

SELECT DISTINCT tablename

Description of all the columns from a table called table_name - describe table equivalent:

SELECT *
FROM pg_table_def
WHERE tablename = 'table_name'
AND schemaname = 'public';

I had similar problem when I tried to build a signed apk for my app.

Strange, it happened only when I wanted to build a release apk, while on debug apk everything worked OK.

Finally, looking on this thread, I checked for support library duplications in build.gradle and removed any duplications but this wasn't enough..

I had to do clean project and only then finally I've got it to work.

You can use a Split :

$text = "test.txt ; 131 136 80 89 119 17 60 123 210 121 188 42 136 200 131 198"
$separator = ";" # you can put many separator like this "; : ,"

$parts = $text.split($separator)

echo $parts[0] # return test.txt
echo $parts[1] # return the part after the separator

package com.tulu.ds;

public class EmailSecurity {
    public static void main(String[] args) {
        System.out.println(returnSecuredEmailID("[email protected]"));
    }
    private static String returnSecuredEmailID(String email){
        String str=email.substring(1, email.lastIndexOf("@")-1);
        return email.replaceAll(email.substring(1, email.lastIndexOf("@")-1),replacewith(str.length(),"*"));
    }
    private static String replacewith(int length,String replace) {
        String finalStr="";
        for(int i=0;i<length;i++){
            finalStr+=replace;
        }
        return finalStr;
    }   
}

java_home always points to the jdk, the compiler that gave you the classes, and the jre is thw way that your browser or whatever will the compiled classes so it must have matching between jdk and jre in the version.

If your UIBarButtonItem is already allocated like in a storyboard. (printBtn)

    let btn = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
    btn.setImage(UIImage(named: Constants.ImageName.print)?.withRenderingMode(.alwaysTemplate), for: .normal)
    btn.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handlePrintPress(tapGesture:))))
    printBtn.customView = btn

I agree this code works, to size an ImageIcon from a file for display while keeping the aspect ratio I have used the below.

/*
 * source File of image, maxHeight pixels of height available, maxWidth pixels of width available
 * @return an ImageIcon for adding to a label
 */


public ImageIcon rescaleImage(File source,int maxHeight, int maxWidth)
{
    int newHeight = 0, newWidth = 0;        // Variables for the new height and width
    int priorHeight = 0, priorWidth = 0;
    BufferedImage image = null;
    ImageIcon sizeImage;

    try {
            image = ImageIO.read(source);        // get the image
    } catch (Exception e) {

            e.printStackTrace();
            System.out.println("Picture upload attempted & failed");
    }

    sizeImage = new ImageIcon(image);

    if(sizeImage != null)
    {
        priorHeight = sizeImage.getIconHeight(); 
        priorWidth = sizeImage.getIconWidth();
    }

    // Calculate the correct new height and width
    if((float)priorHeight/(float)priorWidth > (float)maxHeight/(float)maxWidth)
    {
        newHeight = maxHeight;
        newWidth = (int)(((float)priorWidth/(float)priorHeight)*(float)newHeight);
    }
    else 
    {
        newWidth = maxWidth;
        newHeight = (int)(((float)priorHeight/(float)priorWidth)*(float)newWidth);
    }


    // Resize the image

    // 1. Create a new Buffered Image and Graphic2D object
    BufferedImage resizedImg = new BufferedImage(newWidth, newHeight, BufferedImage.TYPE_INT_RGB);
    Graphics2D g2 = resizedImg.createGraphics();

    // 2. Use the Graphic object to draw a new image to the image in the buffer
    g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g2.drawImage(image, 0, 0, newWidth, newHeight, null);
    g2.dispose();

    // 3. Convert the buffered image into an ImageIcon for return
    return (new ImageIcon(resizedImg));
}

Use <td valign="top" style="width: 259px"> instead...

In testing IE7/8/9 I was getting an ActiveX warning trying to use this code snippet:

filter:progid:DXImageTransform.Microsoft.gradient

After removing this the warning went away. I know this isn't an answer, but I thought it was worthwhile to note.

"Select your text, right click, then choose Style Token and then using 1st style (2nd style, etc …). At the moment is not possible to save the style tokens but there is an idea pending on Idea torrent you may vote for if your are interested in that."

It should be default, but it might be hidden.

"It might be that something happened to your contextMenu.xml so that you only get the basic standard. Have a look in NPPs config folder (%appdata%\Notepad++\) if the contextMenu.xml is there. If no: that would be the answer; if yes: it might be defect. Anyway you can grab the original standart contextMenu.xml from here and place it into the config folder (or replace the existing xml). Start NPP and you should have quite a long context menu. Tip: have a look at the contextmenu.xml itself - because you're allowed to change it to your own needs."

As a Safeguard: Disable Scriptlets For Good

As another question is discussing, you can and always should disable scriptlets in your web.xml web application descriptor.

I would always do that in order to prevent any developer adding scriptlets, especially in bigger companies where you will lose overview sooner or later. The web.xml settings look like this:

<jsp-config>
  <jsp-property-group>
    <url-pattern>*.jsp</url-pattern>
     <scripting-invalid>true</scripting-invalid>
  </jsp-property-group>
</jsp-config>

Here's the simplest, most robust, and scalable solution to get tabs on the bottom of the screen.

1. In your vertical LinearLayout, put the FrameLayout above the TabWidget
2. Set layout_height to wrap_content on both FrameLayout and TabWidget
3. Set FrameLayout's android:layout_weight="1"
4. Set TabWidget's android:layout_weight="0" (0 is default, but for emphasis, readability, etc)
5. Set TabWidget's android:layout_marginBottom="-4dp" (to remove the bottom divider)

Full code:

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:padding="5dp"
            android:layout_weight="1"/>

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0"
            android:layout_marginBottom="-4dp"/>

    </LinearLayout>

</TabHost>

This code will be useful for any internal link on the web

    $("[href^='#']").click(function() {
        id=$(this).attr("href")

        }, 2000);
    });

The accepted answer has it spot on, but if you might want to specify which class label should be assigned to a specific color or label you could do the following. I did a little label gymnastics with the colorbar, but making the plot itself reduces to a nice one-liner. This works great for plotting the results from classifications done with sklearn. Each label matches a (x,y) coordinate.

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

x = [4,8,12,16,1,4,9,16]
y = [1,4,9,16,4,8,12,3]
label = [0,1,2,3,0,1,2,3]
colors = ['red','green','blue','purple']

fig = plt.figure(figsize=(8,8))
plt.scatter(x, y, c=label, cmap=matplotlib.colors.ListedColormap(colors))

cb = plt.colorbar()
loc = np.arange(0,max(label),max(label)/float(len(colors)))
cb.set_ticks(loc)
cb.set_ticklabels(colors)

Using a slightly modified version of this answer, one can generalise the above for N colors as follows:

import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt

N = 23 # Number of labels

# setup the plot
fig, ax = plt.subplots(1,1, figsize=(6,6))
# define the data
x = np.random.rand(1000)
y = np.random.rand(1000)
tag = np.random.randint(0,N,1000) # Tag each point with a corresponding label    

# define the colormap
cmap = plt.cm.jet
# extract all colors from the .jet map
cmaplist = [cmap(i) for i in range(cmap.N)]
# create the new map
cmap = cmap.from_list('Custom cmap', cmaplist, cmap.N)

# define the bins and normalize
bounds = np.linspace(0,N,N+1)
norm = mpl.colors.BoundaryNorm(bounds, cmap.N)

# make the scatter
scat = ax.scatter(x,y,c=tag,s=np.random.randint(100,500,N),cmap=cmap,     norm=norm)
# create the colorbar
cb = plt.colorbar(scat, spacing='proportional',ticks=bounds)
cb.set_label('Custom cbar')
ax.set_title('Discrete color mappings')
plt.show()

Which gives:

I edited your: Fiddle

html, body{ margin:0; padding:0; overflow:hidden; height:100% }
.header { margin: 0 auto; width:500px; height:30px; background-color:#dadada;}
.wrapper{ margin: 0 auto; width:500px; overflow:scroll; height: 100%;}

Giving the html-tag a 100% height is the solution. I also deleted the container div. You don't need it when your layout stays like this.

Set the user name as data-username attribute to the button and also a class:

HTML

<input type="button" name="theButton" value="Detail" class="btn" data-username="{{result['username']}}" />

JS

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name != undefined && name != null) {
        window.location = '/player_detail?username=' + name;
    }
});?

EDIT:

Also, you can simply check for undefined && null using:

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name) {
        window.location = '/player_detail?username=' + name;
    }
});?

As, mentioned in this answer

if (name) {            
}

will evaluate to true if value is not:

• null
• undefined
• NaN
• empty string ("")
• 0
• false

The above list represents all possible falsy values in ECMA/Javascript.

DISCLAIMER: I'm one of the devs

IMHO no more info than @Florjon gave is needed. Maybe some small details are left to understand why it might not work for us sometimes.

First of all, the &#xa (hex) or &#10 (dec) inside a <xsl:text/> will always work, but you may not see it.

1. There is no newline in a HTML markup. Using a simple <br/> will do fine. Otherwise you'll see a white space. Viewing the source from the browser will tell you what really happened. However, there are cases you expect this behaviour, especially if the consumer is not directly a browser. For instance, you want to create an HTML page and view its structure formatted nicely with empty lines and idents before serving it to the browser.
2. Remember where you need to use disable-output-escaping and where you don't. Take the following example where I had to create an xml from another and declare its DTD from a stylesheet.

The first version does escape the characters (default for xsl:text)

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output method="xml" indent="yes" encoding="utf-8"/>

    <xsl:template match="/">
        <xsl:text>&lt;!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd"&gt;&#xa;&#xa;&#xd;</xsl:text>
        <xsl:copy>
            <xsl:apply-templates select="*" mode="copy"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="@*|node()" mode="copy">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" mode="copy"/>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

and here is the result:

<?xml version="1.0" encoding="utf-8"?>
&lt;!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd"&gt;

&#13;<Subscriptions>
    <User id="1"/>   
</Subscriptions>

Ok, it does what we expect, escaping is done so that the characters we used are displayed properly. The XML part formatting inside the root node is handled by ident="yes". But with a closer look we see that the newline character &#xa was not escaped and translated as is, performing a double linefeed! I don't have an explanation on this, will be good to know. Anyone?

The second version does not escape the characters so they're producing what they're meant for. The change made was:

<xsl:text disable-output-escaping="yes">&lt;!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd"&gt;&#xa;&#xa;&#xd;</xsl:text>

and here is the result:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd">

<Subscriptions>
    <User id="1"/>   
</Subscriptions>

and that will be ok. Both cr and lf are properly rendered.

3. Don't forget we're talking about nl, not crlf (nl=lf). My first attempt was to use only cr:&#xd and while the output xml was validated by DOM properly.

I was viewing a corrupted xml:

<?xml version="1.0" encoding="utf-8"?>
<Subscriptions>riptions SYSTEM "Subscriptions.dtd">
    <User id="1"/>   
</Subscriptions>

DOM parser disregarded control characters but the rendered didn't. I spent quite some time bumping my head before I realised how silly I was not seeing this!

For the record, I do use a variable inside the body with both CRLF just to be 100% sure it will work everywhere.

You need to

#include <string>

<iostream> declares cout, cin, not string.

You can return a structure from a function (or use the = operator) without any problems. It's a well-defined part of the language. The only problem with struct b = a is that you didn't provide a complete type. struct MyObj b = a will work just fine. You can pass structures to functions as well - a structure is exactly the same as any built-in type for purposes of parameter passing, return values, and assignment.

Here's a simple demonstration program that does all three - passes a structure as a parameter, returns a structure from a function, and uses structures in assignment statements:

#include <stdio.h>

struct a {
   int i;
};

struct a f(struct a x)
{
   struct a r = x;
   return r;
}

int main(void)
{
   struct a x = { 12 };
   struct a y = f(x);
   printf("%d\n", y.i);
   return 0;
}

The next example is pretty much exactly the same, but uses the built-in int type for demonstration purposes. The two programs have the same behaviour with respect to pass-by-value for parameter passing, assignment, etc.:

#include <stdio.h>

int f(int x) 
{
  int r = x;
  return r;
}

int main(void)
{
  int x = 12;
  int y = f(x);
  printf("%d\n", y);
  return 0;
}

Short ways to write lines of text to a file in R could be realised with cat or writeLines as already shown in many answers. Some of the shortest possibilities might be:

cat("Hello\nWorld", file="output.txt")
writeLines("Hello\nWorld", "output.txt")

In case you don't like the "\n" you could also use the following style:

cat("Hello
World", file="output.txt")

writeLines("Hello
World", "output.txt")

While writeLines adds a newline at the end of the file what is not the case for cat. This behaviour could be adjusted by:

writeLines("Hello\nWorld", "output.txt", sep="") #No newline at end of file
cat("Hello\nWorld\n", file="output.txt") #Newline at end of file
cat("Hello\nWorld", file="output.txt", sep="\n") #Newline at end of file

But main difference is that cat uses R objects and writeLines a character vector as argument. So writing out e.g. the numbers 1:10 needs to be casted for writeLines while it can be used as it is in cat:

cat(1:10)
writeLines(as.character(1:10))

and cat can take many objects but writeLines only one vector:

cat("Hello", "World", sep="\n")
writeLines(c("Hello", "World"))

My suggestion would be to use a StringIO object. They emulate files, but reside in memory. So you could do something like this:

# get_zip_data() gets a zip archive containing 'foo.txt', reading 'hey, foo'

import zipfile
from StringIO import StringIO

zipdata = StringIO()
zipdata.write(get_zip_data())
myzipfile = zipfile.ZipFile(zipdata)
foofile = myzipfile.open('foo.txt')
print foofile.read()

# output: "hey, foo"

Or more simply (apologies to Vishal):

myzipfile = zipfile.ZipFile(StringIO(get_zip_data()))
for name in myzipfile.namelist():
    [ ... ]

In Python 3 use BytesIO instead of StringIO:

import zipfile
from io import BytesIO

filebytes = BytesIO(get_zip_data())
myzipfile = zipfile.ZipFile(filebytes)
for name in myzipfile.namelist():
    [ ... ]

The syntax of ng-style is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:

<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>

And then in your controller:

$scope.width = '900px';
$scope.bgColor = 'red';

This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.

You might want to have a look at this specification for CSV. Bear in mind that there is no official recognized specification.

If you do not now the delimiter it will not be possible to do this so you have to find out somehow. If you can do a manual inspection of the file you should quickly be able to see what it is and hard code it in your program. If the delimiter can vary your only hope is to be able to deduce if from the formatting of the known data. When Excel imports CSV files it lets the user choose the delimiter and this is a solution you could use as well.

It looks much like a list of Django ORM model instances.

Why not sort them on query like this:

ut = Tag.objects.order_by('-count')

Use the TextFieldParser class built into the .Net framework.

Here's some code copied from an MSDN forum post by Paul Clement. It converts the CSV into a new in-memory DataTable and then binds the DataGridView to the DataTable

    Dim TextFileReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("C:\Documents and Settings\...\My Documents\My Database\Text\SemiColonDelimited.txt")

    TextFileReader.TextFieldType = FileIO.FieldType.Delimited
    TextFileReader.SetDelimiters(";")

    Dim TextFileTable As DataTable = Nothing

    Dim Column As DataColumn
    Dim Row As DataRow
    Dim UpperBound As Int32
    Dim ColumnCount As Int32
    Dim CurrentRow As String()

    While Not TextFileReader.EndOfData
        Try
            CurrentRow = TextFileReader.ReadFields()
            If Not CurrentRow Is Nothing Then
                ''# Check if DataTable has been created
                If TextFileTable Is Nothing Then
                    TextFileTable = New DataTable("TextFileTable")
                    ''# Get number of columns
                    UpperBound = CurrentRow.GetUpperBound(0)
                    ''# Create new DataTable
                    For ColumnCount = 0 To UpperBound
                        Column = New DataColumn()
                        Column.DataType = System.Type.GetType("System.String")
                        Column.ColumnName = "Column" & ColumnCount
                        Column.Caption = "Column" & ColumnCount
                        Column.ReadOnly = True
                        Column.Unique = False
                        TextFileTable.Columns.Add(Column)
                    Next
                End If
                Row = TextFileTable.NewRow
                For ColumnCount = 0 To UpperBound
                    Row("Column" & ColumnCount) = CurrentRow(ColumnCount).ToString
                Next

installing python packages offline

For windows users:

To download into a file open your cmd and folow this:

cd <*the file-path where you want to save it*>

pip download <*package name*>

the package and the dependencies will be downloaded in the current working directory.

To install from the current working directory:

set your folder where you downloaded as the cwd then follow these:

pip install <*the package name which is downloded as .whl*> --no-index --find-links <*the file locaation where the files are downloaded*>

this will search for dependencies in that location.

Ok solved it.

Added the solution to GitHub - http://gregorypratt.github.com/AngularDynamicRouting

In my app.js routing config:

$routeProvider.when('/pages/:name', {
    templateUrl: '/pages/home.html', 
    controller: CMSController 
});

Then in my CMS controller:

function CMSController($scope, $route, $routeParams) {

    $route.current.templateUrl = '/pages/' + $routeParams.name + ".html";

    $.get($route.current.templateUrl, function (data) {
        $scope.$apply(function () {
            $('#views').html($compile(data)($scope));
        });
    });
    ...
}
CMSController.$inject = ['$scope', '$route', '$routeParams'];

With #views being my <div id="views" ng-view></div>

So now it works with standard routing and dynamic routing.

To test it I copied about.html called it portfolio.html, changed some of it's contents and entered /#/pages/portfolio into my browser and hey presto portfolio.html was displayed....

Updated Added $apply and $compile to the html so that dynamic content can be injected.

lots of correct answers, but as I landed here to copy & paste a folder rename with history, I found that this

git mv <old name> <new name>

will move the old folder (itself) to nest within the new folder

while

git mv <old name>/ <new name>

(note the '/') will move the nested content from the old folder to the new folder

both commands didn't copy along the history of nested files. I eventually renamed each nested folder individually ?

git mv <old name>/<nest-folder> <new name>/<nest-folder>

add:

margin: 0 0 3px 0;

to your #access li and move

background: #0f84e8; /* Show a solid color for older browsers */

to the #access a and take out the border-bottom. Then it will work

Here: http://jsfiddle.net/bpmKW/4/

You are writing if(true) so it will always show "Hello " message.

You should take decision on the basis of value of n returned.

You could do the following:

var inputType = $('#inputid').attr('type');

I had exactly the same problem. It's because default python is in version 2 You need to link to the version 3.

>sudo rm -rf /usr/bin/python
>sudo ln -s /usr/bin/python3.5 /usr/bin/python

DROP Table

DROP TABLE [table_name];

The DROP command is used to remove a table from the database. It is a DDL command. All the rows, indexes and privileges of the table will also be removed. DROP operation cannot be rolled back.

DELETE Table

DELETE FROM [table_name]
WHERE [condition];

DELETE FROM [table_name];

The DELETE command is a DML command. It can be used to delete all the rows or some rows from the table based on the condition specified in WHERE clause. It is executed using a row lock, each row in the table is locked for deletion. It maintain the transaction log, so it is slower than TRUNCATE. DELETE operations can be rolled back.

TRUNCATE Table

TRUNCATE TABLE [table_name];

The TRUNCATE command removes all rows from a table. It won't log the deletion of each row, instead it logs the deallocation of the data pages of the table, which makes it faster than DELETE. It is executed using a table lock and whole table is locked for remove all records. It is a DDL command. TRUNCATE operations cannot be rolled back.

Comment from answer: "make sure you use the same open connection for all the database calls inside the transaction. – Magnus"

Our users are stored in a separate db from the data I was working with in the transactions. Opening the db connection to get the user was causing this error for me. Moving the other db connection and user lookup outside of the transaction scope fixed the error.

For me a Git repository (not GitHub) was already created, but empty. This was my solution for adding the existing project to the Git repository:

1. I cloned and checked out a repository with Git Extensions.
2. Then I copied my existing project files into this repository.
3. Added a .gitignore file.
4. Staged and committed all files.
5. Pushed onto the remote repository.

It would be interesting to see this all done directly in Visual Studio 2015 without tools like Git Extensions, but the things I tried in Visual Studio didn't work (Add to source control is not available for my project, adding a remote didn't help, etc.).

I know this is an old item, but thought I'd throw in another option to consider.

As the original string doesn't include the "T" demarker, the default implementation in Angular doesn't recognize it as a date. You can force it using new Date, but that is a bit of a pain on an array. Since you can pipe filters together, you might be able to use a filter to convert your input to a date and then apply the date: filter on the converted date. Create a new custom filter as follows:

app
.filter("asDate", function () {
    return function (input) {
        return new Date(input);
    }
});

Then in your markup, you can pipe the filters together:

{{item.myDateTimeString | asDate | date:'shortDate'}}

It's HTML character references for encoding a character by its decimal code point

Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe

please try with below query

select id,numbers_from,created_date,amount_numbers,SMS_text 
from Test_Table
where 
convert(datetime, convert(varchar(10), created_date, 102))  <= convert(datetime,'2013-04-12')

Using a form in a view pretty much explains it.

The standard pattern for processing a form in a view looks like this:

def contact(request):
    if request.method == 'POST': # If the form has been submitted...
        form = ContactForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            # Process the data in form.cleaned_data
            # ...

            print form.cleaned_data['my_form_field_name']

            return HttpResponseRedirect('/thanks/') # Redirect after POST
    else:
        form = ContactForm() # An unbound form

    return render_to_response('contact.html', {
        'form': form,
    })

Since the other answers here, even though correct, do not explicitly address your initial doubts, I'll do it.

If you call string.Replace(char oldChar, char newChar) it will replace the occurrences of a character with another character. It is a one-for-one replacement. Because of this the length of the resulting string will be the same.

What you want is to remove the dashes, which, obviously, is not the same thing as replacing them with another character. You cannot replace it by "no character" because 1 character is always 1 character. That's why you need to use the overload that takes strings: strings can have different lengths. If you replace a string of length 1, with a string of length 0, the effect is that the dashes are gone, replaced by "nothing".

Take a look at the various test operators (this is for the test command itself, but the built-in BASH and TCSH tests are more or less the same).

You'll notice that -x FILE says FILE exists and execute (or search) permission is granted.

BASH, Bourne, Ksh, Zsh Script

if [[ -x "$file" ]]
then
    echo "File '$file' is executable"
else
    echo "File '$file' is not executable or found"
fi

TCSH or CSH Script:

if ( -x "$file" ) then
    echo "File '$file' is executable"
else
    echo "File '$file' is not executable or found"
endif

To determine the type of file it is, try the file command. You can parse the output to see exactly what type of file it is. Word 'o Warning: Sometimes file will return more than one line. Here's what happens on my Mac:

$ file /bin/ls    
/bin/ls: Mach-O universal binary with 2 architectures
/bin/ls (for architecture x86_64):  Mach-O 64-bit executable x86_64
/bin/ls (for architecture i386):    Mach-O executable i386

The file command returns different output depending upon the OS. However, the word executable will be in executable programs, and usually the architecture will appear too.

Compare the above to what I get on my Linux box:

$ file /bin/ls
/bin/ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), stripped

And a Solaris box:

$ file /bin/ls
/bin/ls:        ELF 32-bit MSB executable SPARC Version 1, dynamically linked, stripped

In all three, you'll see the word executable and the architecture (x86-64, i386, or SPARC with 32-bit).

Addendum

Thank you very much, that seems the way to go. Before I mark this as my answer, can you please guide me as to what kind of script shell check I would have to perform (ie, what kind of parsing) on 'file' in order to check whether I can execute a program ? If such a test is too difficult to make on a general basis, I would at least like to check whether it's a linux executable or osX (Mach-O)

Off the top of my head, you could do something like this in BASH:

if [ -x "$file" ] && file "$file" | grep -q "Mach-O"
then
    echo "This is an executable Mac file"
elif [ -x "$file" ] && file "$file" | grep -q "GNU/Linux"
then
    echo "This is an executable Linux File"
elif [ -x "$file" ] && file "$file" | grep q "shell script"
then
    echo "This is an executable Shell Script"
elif [ -x "$file" ]
then
    echo "This file is merely marked executable, but what type is a mystery"
else
    echo "This file isn't even marked as being executable"
fi

Basically, I'm running the test, then if that is successful, I do a grep on the output of the file command. The grep -q means don't print any output, but use the exit code of grep to see if I found the string. If your system doesn't take grep -q, you can try grep "regex" > /dev/null 2>&1.

Again, the output of the file command may vary from system to system, so you'll have to verify that these will work on your system. Also, I'm checking the executable bit. If a file is a binary executable, but the executable bit isn't on, I'll say it's not executable. This may not be what you want.

I am using httpclient 4.4.

For solr query I used the following way and it worked.

NameValuePair nv2 = new BasicNameValuePair("fq","(active:true) AND (category:Fruit OR category1:Vegetable)");
nvPairList.add(nv2);
NameValuePair nv3 = new BasicNameValuePair("wt","json");
nvPairList.add(nv3);
NameValuePair nv4 = new BasicNameValuePair("start","0");
nvPairList.add(nv4);
NameValuePair nv5 = new BasicNameValuePair("rows","10");
nvPairList.add(nv5);

HttpClient client = HttpClientBuilder.create().build();
HttpGet request = new HttpGet(url);
URI uri = new URIBuilder(request.getURI()).addParameters(nvPairList).build();
            request.setURI(uri);

HttpResponse response = client.execute(request);    
if (response.getStatusLine().getStatusCode() != 200) {

}

BufferedReader br = new BufferedReader(
                             new InputStreamReader((response.getEntity().getContent())));

String output;
System.out.println("Output  .... ");
String respStr = "";
while ((output = br.readLine()) != null) {
    respStr = respStr + output;
    System.out.println(output);
}

A much more simple solution (thanks to http://daniel.fone.net.nz/blog/2014/12/01/fixing-connection-errors-after-upgrading-postgres/) . I had upgraded to postgres 9.4. In my case, all I needed to do (after a day of googling and not succeeding)

gem uninstall pg
gem uninstall activerecord-postgresql-adapter
bundle install

Restart webrick, and done!

For non-grouped elements, name and id should be same. In this case you gave name as 'sp' and id as 'sp_100'. Don't do that, do it like this:

HTML:

<input type="hidden" id="msg" name="msg" value="" style="display:none"/>
<input type="checkbox" name="sp" value="100" id="sp">

Javascript:

var Msg="abc";
document.getElementById('msg').value = Msg;
document.getElementById('sp').checked = true;

Yes, you can do this quite easily. Click on your project in the project explorer or Navigator, go to the Search menu at the top, click File..., input your search string, and make sure that 'Selected Resources' or 'Enclosing Projects' is selected, then hit search. The alternative way to open the window is with Ctrl-H. This may depend on your keyboard accelerator configuration.

In my case the --force option didn't quite work. I could still see the pod ! It was stuck in Terminating/Unknown mode. So after running

kubectl delete pods <pod> -n redis --grace-period=0 --force

I ran

kubectl patch pod <pod> -p '{"metadata":{"finalizers":null}}'

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

You have to check on this.

HTML

<button id="saveActionId"> Save </button>

manifest.json

  "permissions": [
    "activeTab",
    "tabs"
   ]

JavaScript
The below code will save all the urls of active window into JSON object as part of button click.

var saveActionButton = document.getElementById('saveActionId');
saveActionButton.addEventListener('click', function() {
    myArray = [];
    chrome.tabs.query({"currentWindow": true},  //{"windowId": targetWindow.id, "index": tabPosition});
    function (array_of_Tabs) {  //Tab tab
        arrayLength = array_of_Tabs.length;
        //alert(arrayLength);
        for (var i = 0; i < arrayLength; i++) {
            myArray.push(array_of_Tabs[i].url);
        }
        obj = JSON.parse(JSON.stringify(myArray));
    });
}, false);

Here is my recursive approach:

function visit(object) {
    if (isIterable(object)) {
        forEachIn(object, function (accessor, child) {
            visit(child);
        });
    }
    else {
        var value = object;
        console.log(value);
    }
}

function forEachIn(iterable, functionRef) {
    for (var accessor in iterable) {
        functionRef(accessor, iterable[accessor]);
    }
}

function isIterable(element) {
    return isArray(element) || isObject(element);
}

function isArray(element) {
    return element.constructor == Array;
}

function isObject(element) {
    return element.constructor == Object;
}

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

As @web-tiki already show a way to use vh/vw, I also need a way to center in the screen, here is a snippet code for 9:16 portrait.

.container {
  width: 100vw;
  height: calc(100vw * 16 / 9);
  transform: translateY(calc((100vw * 16 / 9 - 100vh) / -2));
}

translateY will keep this center in the screen. calc(100vw * 16 / 9) is expected height for 9/16.(100vw * 16 / 9 - 100vh) is overflow height, so, pull up overflow height/2 will keep it center on screen.

For landscape, and keep 16:9, you show use

.container {
  width: 100vw;
  height: calc(100vw * 9 / 16);
  transform: translateY(calc((100vw * 9 / 16 - 100vh) / -2));
}

The ratio 9/16 is ease to change, no need to predefined 100:56.25 or 100:75.If you want to ensure height first, you should switch width and height, e.g. height:100vh;width: calc(100vh * 9 / 16) for 9:16 portrait.

If you want to adapted for different screen size, you may also interest

• background-size cover/contain
  • Above style is similar to contain, depends on width:height ratio.
• object-fit
  • cover/contain for img/video tag
• @media (orientation: portrait)/@media (orientation: landscape)
  • Media query for portrait/landscape to change the ratio.

If you use eclipse, maybe PyUML. Haven't used it, though.

From the article Override equals and hashCode in Java:

Default implementation of equals() class provided by java.lang.Object compares memory location and only return true if two reference variable are pointing to same memory location i.e. essentially they are same object.

Java recommends to override equals and hashCode method if equality is going to be defined by logical way or via some business logic: example:

many classes in Java standard library does override it e.g. String overrides equals, whose implementation of equals() method return true if content of two String objects are exactly same

Integer wrapper class overrides equals to perform numerical comparison etc.

A slight adaptation to the solution above by kingjeffrey for when you want to create and echo the CSV within a template (Ie - most frameworks will have output buffering enabled and you are required to set headers etc in controllers.)

// Create Some data
<?php
    $data = array(
        array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
        array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
        array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
    );


// Create a stream opening it with read / write mode
$stream = fopen('data://text/plain,' . "", 'w+');

// Iterate over the data, writting each line to the text stream
foreach ($data as $val) {
    fputcsv($stream, $val);
}

// Rewind the stream
rewind($stream);

// You can now echo it's content
echo stream_get_contents($stream);

// Close the stream 
fclose($stream);

Credit to Kingjeffrey above and also to this blog post where I found the information about creating text streams.

Beware of the use of push method, if you don't use indexes, it won't work!

var main2dArray: Things[][] = []

main2dArray.push(someTmp1dArray)
main2dArray.push(someOtherTmp1dArray)

gives only a 1 line array!

use

main2dArray[0] = someTmp1dArray
main2dArray[1] = someOtherTmp1dArray

to get your 2d array working!!!

Other beware! foreach doesn't seem to work with 2d arrays!

echo "test" | mailx -r [email protected] -s 'test' [email protected]

It works in OpenBSD.

you can also loop trough your list:

def fun():
  for i in x:
    print(i)

x = ["1",1,"a",8]
fun()

Try getppid() if you want your C program to print your shell's PID.

Was having the same issue. I solved it by adding the following to viewDidLoad.

self.extendedLayoutIncludesOpaqueBars = true

As explained above, you can use the Firebase default push id.

If you want something numeric you can do something based on the timestamp to avoid collisions

f.e. something based on date,hour,second,ms, and some random int at the end

01612061353136799031

Which translates to:

016-12-06 13:53:13:679 9031

It all depends on the precision you need (social security numbers do the same with some random characters at the end of the date). Like how many transactions will be expected during the day, hour or second. You may want to lower precision to favor ease of typing.

You can also do a transaction that increments the number id, and on success you will have a unique consecutive number for that user. These can be done on the client or server side.

Add parenthesis around the lines. Example:

$ (
sudo apt-get update
dokku apps
dokku ps:stop APP # repeat to shut down each running app
sudo apt-get install -qq -y dokku herokuish sshcommand plugn
dokku ps:rebuildall # rebuilds all applications
)

I have found the solution in spring boot by using @CrossOrigin annotation.

@RestController
@CrossOrigin
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

After trying all the other solutions posted here (Skype, updates to C++ Redistributable), I found that another process was using port 80. The culprit was Microsoft Internet Information Server (IIS). You can stop the service from the command line on Windows 7/Vista:

net stop was /y

Or set the service to not start automatically by going to Services: click Start, click Control Panel, click Performance and Maintenance, click Administrative Tools, and then double-click Services. There, locate "WAS Service" and "World Wide Web Publication Service" and set them to manual or deactivate them completely.

Then restart the WAMP server.

Try BatToExe converter. It will convert your batch file to an executable, and allow you to set an icon for it.

difference between Primary Key and Unique Key

Both Primary key and Unique Key are used to uniquely define of a row in a table. Primary Key creates a clustered index of the column whereas a Unique creates an unclustered index of the column.

A Primary Key doesn’t allow NULL value, however a Unique Key does allow one NULL value.

Installing Android SDKs is done via the "Android SDK and AVD Manager"... there's a shortcut on Eclipse's "Window" menu, or you can run the .exe from the root of your existing Android SDK installation.

Yes I think installing the 2.3 SDK will fix your problem... you can install older SDKs at the same time. The important thing is that the structure of the SDK changed in 2.3 with some tools (such as ADB) moving from sdkroot\tools to sdkroot\platform-tools. Quite possibly the very latest ADT plugin isn't massively backwards-compatible re that change.

The current root password must be empty. Then under "new root password" enter your password and confirm.

Try,

var newList = 
(
from x in empCollection
select new {Loc = x.empLoc, PL = x.empPL, Shift = x.empShift}
).Distinct();

In the default settings, VS Code uses the following fonts (14 pt) in descending order:

• Monaco
• Menlo
• Consolas
• "Droid Sans Mono"
• "Inconsolata"
• "Courier New"
• monospace (fallback)

How to verify: VS Code runs in a browser. In the first version, you could hit F12 to open the Developer Tools. Inspecting the DOM, you can find a containing several s that make up that line of code. Inspecting one of those spans, you can see that font-family is just the list above.

1.one-off uses

List<T> list=Arrays.asList(...)
list.contains(...)

2.use HashSet for performance consideration if you use more than once.

Set <T>set =new HashSet<T>(Arrays.asList(...));
set.contains(...)

If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.
