You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

There should be a way to solve this pretty easily with external config sections and an extra deployment step that drops a deployment specific external .config file into a known location. We typically use this solution to handle the different server configurations for our different deployment environments (Staging, QA, production, etc) with our "dev box" being the default if no special copy occurs.

Updating the config didn't work for me, but I was able to edit the binding programmatically:

private YourAPIClient GetClient()
{
    Uri baseAddress = new Uri(APIURL);

    var binding = new BasicHttpBinding();
    binding.MaxReceivedMessageSize = 20000000;
    binding.MaxBufferSize = 20000000;
    binding.MaxBufferPoolSize = 20000000;
    binding.AllowCookies = true;

    var readerQuotas = new XmlDictionaryReaderQuotas();
    readerQuotas.MaxArrayLength = 20000000;
    readerQuotas.MaxStringContentLength = 20000000;
    readerQuotas.MaxDepth = 32;
    binding.ReaderQuotas = readerQuotas;

    if (baseAddress.Scheme.ToLower() == "https")
        binding.Security.Mode = BasicHttpSecurityMode.Transport;

    var client = new YourAPIClient(binding, new EndpointAddress(baseAddress));
    return client;
}

Declare @variable int
Exec @variable = proc_name

Like others have mentioned, I think of roles as containers for more granular permissions.

Although I found the Hierarchy Role implementation to be lacking fine control of these granular permission.
So I created a library to manage the relationships and inject the permissions as granted authorities in the security context.

I may have a set of permissions in the app, something like CREATE, READ, UPDATE, DELETE, that are then associated with the user's Role.

Or more specific permissions like READ_POST, READ_PUBLISHED_POST, CREATE_POST, PUBLISH_POST

These permissions are relatively static, but the relationship of roles to them may be dynamic.

Example -

@Autowired 
RolePermissionsRepository repository;

public void setup(){
  String roleName = "ROLE_ADMIN";
  List<String> permissions = new ArrayList<String>();
  permissions.add("CREATE");
  permissions.add("READ");
  permissions.add("UPDATE");
  permissions.add("DELETE");
  repository.save(new RolePermissions(roleName, permissions));
}

You may create APIs to manage the relationship of these permissions to a role.

I don't want to copy/paste another answer, so here's the link to a more complete explanation on SO.

To re-use my implementation, I created a repo. Please feel free to contribute!

The install.packages command looks through the .libPaths variable. Here's what mine defaults to on OSX:

> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

I don't install packages there by default, I prefer to have them installed in my home directory. In my .Rprofile, I have this line:

.libPaths( "/Users/tex/lib/R" )

This adds the directory "/Users/tex/lib/R" to the front of the .libPaths variable.

Use Iterator instead of Array List

Have a set be converted to iterator with type match

And move to the next element and remove

Iterator<Insured> itr = insuredSet.iterator();
while (itr.hasNext()) { 
    itr.next();
    itr.remove();
}

Moving to the next is important here as it should take the index to remove element.

Example for CoffeeScript:

test = (str, callback) ->
  data = "Input values"
  $.ajax
    type: "post"
    url: "http://www.mydomain.com/ajaxscript"
    data: data
    success: callback

test (data, textStatus, xhr) ->
  alert data + "\t" + textStatus

list multiplication works.

>>> [0] * 10
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

I'd like to expand on Leor's suggestion for anyone confused on how to compute the nearest location and actually provide a working solution:

I'm using markers in a markers array e.g. var markers = [];.

Then let's have our position as something like var location = new google.maps.LatLng(51.99, -0.74);

Then we simply reduce our markers against the location we have like so:

markers.reduce(function (prev, curr) {

    var cpos = google.maps.geometry.spherical.computeDistanceBetween(location.position, curr.position);
    var ppos = google.maps.geometry.spherical.computeDistanceBetween(location.position, prev.position);

    return cpos < ppos ? curr : prev;

}).position

What pops out is your closest marker LatLng object.

This solution will work for any depth level (specifying how deep a nested array structure should be) of array.

function flatten(obj) {
    var out = [];
    function cleanElements(input) {
        for (var i  in input){
            if (input[i]instanceof Array){
                cleanElements(input[i]);
            }
            else {
                out.push(input[i]);
            }
        }
    }
    cleanElements(obj);
    return (out);
}

I suspect its a new feature since this post was created - pass parameters to the script block using $Using:var. Then its a simple mater to pass parameters provided the script is already on the machine or in a known network location relative to the machine

Taking the main example it would be:

icm -cn $Env:ComputerName { 
    C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 -one "uno" -two "dos" -Debug -Clear $Using:Clear
}

In my case it was the problem of building the extension, I was pointing at an extension src (with manifest and everything) but without a build.

If you run into this scenario run npm i then npm build

Here it is some code:

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

See more examples in this article, you may need to take a look to impersonation.

Check this answer: https://stackoverflow.com/a/7346598/1764509

$.getJSON("test.json", function(json) {
    console.log(json); // this will show the info it in firebug console
});

For handling line-breaks specifically, I tried a number of options before finally settling for this:

{% set list1 = data.split('\n') %}
{% for item in list1 %}
{{ item }}
  {% if not loop.last %}
  <br/>
  {% endif %}
{% endfor %}

The nice thing about this approach is that it's compatible with the auto-escaping, leaving everything nice and safe. It can also be combined with filters, like urlize.

Of course it's similar to Helge's answer, but doesn't need a macro (relying instead on Jinja's built-in split function) and also doesn't add an unnecesssary <br/> after the last item.

In your case, it's the best to use rotate option from transform property as mentioned before. There is also writing-mode property and it works like rotate(90deg) so in your case, it should be rotated after it's applied. Even it's not the right solution in this case but you should be aware of this property.

Example:

writing-mode:vertical-rl;

More about transform: https://kolosek.com/css-transform/

More about writing-mode: https://css-tricks.com/almanac/properties/w/writing-mode/

This is what worked for me:

git fetch --all 
git log production/master

Note that this fetches from ALL remotes, i.e. potentially you "have to clone 2GB worth of objects just to look through the commit logs".

InstallUtil classes ( ServiceInstaller ) are considered an anti-pattern by the Windows Installer community. It's a fragile, out of process, reinventing of the wheel that ignores the fact that Windows Installer has built-in support for Services.

Visual Studio deployment projects ( also not highly regarded and deprecated in the next release of Visual Studio ) do not have native support for services. But they can consume merge modules. So I would take a look at this blog article to understand how to create a merge module using Windows Installer XML that can express the service and then consume that merge module in your VDPROJ solution.

Note: IF "%1"=="" will cause problems if %1 is enclosed in quotes itself.

In that case, use IF [%1]==[] or, in NT 4 (SP6) and later only, IF "%~1"=="" instead.

Use this echo statement

 echo -e "Hai\nHello\nTesting\n"

The output is

According to the following post, you can't do this with log4j: Use MaxBackupIndex in DailyRollingFileAppender -log4j

As far as I know, this functionality was supposed to make it into log4j 2.0 but that effort got sidetracked. According to the logback website, logback is the intended successor to log4j so you might consider using that.

There's an API called SLF4J which provides a common API to logging. It will load up the actual logging implementation at runtime so depending on the configuration that you have provided, it might use java.util.log or log4j or logback or any other library capable of providing logging facilities. There'll be a bit of up-front work to go from using log4j directly to using SLF4J but they provide some tools to automate this process. Once you've converted your code to use SLF4J, switching logging backends should simply be a case of changing the config file.

Yes. If you want to fetch a limited subset of objects, you can with the below code:

Example:

obj=emp.objects.all()[0:10]

The beginning 0 is optional, so

obj=emp.objects.all()[:10]

The above code returns the first 10 instances.

git rev-list --exclude=master --branches --no-walk

will list the tips of every branch that isn't master.

git rev-list master --not $(git rev-list --exclude=master --branches --no-walk)

will list every commit in master's history that's not in any other branch's history.

Sequencing is important for the options that set up the filter pipeline for commit selection, so --branches has to follow any exclusion patterns it's supposed to apply, and --no-walk has to follow the filters supplying commits rev-list isn't supposed to walk.

ConcurrentLinkedQueue means no locks are taken (i.e. no synchronized(this) or Lock.lock calls). It will use a CAS - Compare and Swap operation during modifications to see if the head/tail node is still the same as when it started. If so, the operation succeeds. If the head/tail node is different, it will spin around and try again.

LinkedBlockingQueue will take a lock before any modification. So your offer calls would block until they get the lock. You can use the offer overload that takes a TimeUnit to say you are only willing to wait X amount of time before abandoning the add (usually good for message type queues where the message is stale after X number of milliseconds).

Fairness means that the Lock implementation will keep the threads ordered. Meaning if Thread A enters and then Thread B enters, Thread A will get the lock first. With no fairness, it is undefined really what happens. It will most likely be the next thread that gets scheduled.

As for which one to use, it depends. I tend to use ConcurrentLinkedQueue because the time it takes my producers to get work to put onto the queue is diverse. I don't have a lot of producers producing at the exact same moment. But the consumer side is more complicated because poll won't go into a nice sleep state. You have to handle that yourself.

As for the testing, you should use from Spring 4.1 which will overwrite the properties defined in other places:

@TestPropertySource("classpath:application-test.properties")

Test property sources have higher precedence than those loaded from the operating system's environment or Java system properties as well as property sources added by the application like @PropertySource

If a certificate expires in the middle of project debugging, you must do a manual uninstall:

Please execute adb uninstall <package_name> in a shell.

Something to keep in mind is that this error isn't only due to self signed certs. The new Entrust CA certs fail with the same error, and the right thing to do is to update the server with the appropriate root certs, not to disable this important security feature.

Array with range of numbers at random order:

$numbers = range(1, 20);
shuffle($numbers);

Wrapped function:

function UniqueRandomNumbersWithinRange($min, $max, $quantity) {
    $numbers = range($min, $max);
    shuffle($numbers);
    return array_slice($numbers, 0, $quantity);
}

Example:

<?php
print_r( UniqueRandomNumbersWithinRange(0,25,5) );
?>

Result:

 Array
(
    [0] => 14
    [1] => 16
    [2] => 17
    [3] => 20
    [4] => 1
)

In DJango 3.0 the default value of a BooleanField in model.py is set like this:

class model_name(models.Model):
example_name = models.BooleanField(default=False)

I wanted the dropdown to select the matching value of the id in the action method. The trick is to set the Selected property when creating the SelectListItem Collection. It would not work any other way, perhaps I missed something but in end, it is more elegant in my option.

You can write any method that returns a boolean to set the Selected value based on your requirements, in my case I used the existing Equal Method

public ActionResult History(long id)
        {
            var app = new AppLogic();
            var historyVM = new ActivityHistoryViewModel();

            historyVM.ProcessHistory = app.GetActivity(id);
            historyVM.Process = app.GetProcess(id);
            var processlist = app.GetProcessList();

            historyVM.ProcessList = from process in processlist
                                    select new SelectListItem
                                    {
                                        Text = process.ProcessName,
                                        Value = process.ID.ToString(),
                                        Selected = long.Equals(process.ID, id)                                    

                                    };

            var listitems = new List<SelectListItem>();

            return View(historyVM);
        }

I ended up wrapping archiver to emulate JSZip, as refactoring through my project woult take too much effort. I understand Archiver might not be the best choice, but here you go.

// USAGE:
const zip=JSZipStream.to(myFileLocation)
    .onDone(()=>{})
    .onError(()=>{});

zip.file('something.txt','My content');
zip.folder('myfolder').file('something-inFolder.txt','My content');
zip.finalize();

// NodeJS file content:
    var fs = require('fs');
    var path = require('path');
    var archiver = require('archiver');

  function zipper(archive, settings) {
    return {
        output: null,
        streamToFile(dir) {
            const output = fs.createWriteStream(dir);
            this.output = output;
            archive.pipe(output);

            return this;
        },
        file(location, content) {
            if (settings.location) {
                location = path.join(settings.location, location);
            }
            archive.append(content, { name: location });
            return this;
        },
        folder(location) {
            if (settings.location) {
                location = path.join(settings.location, location);
            }
            return zipper(archive, { location: location });
        },
        finalize() {
            archive.finalize();
            return this;
        },
        onDone(method) {
            this.output.on('close', method);
            return this;
        },
        onError(method) {
            this.output.on('error', method);
            return this;
        }
    };
}

exports.JSzipStream = {
    to(destination) {
        console.log('stream to',destination)
        const archive = archiver('zip', {
            zlib: { level: 9 } // Sets the compression level.
        });
        return zipper(archive, {}).streamToFile(destination);
    }
};

I know this is a super old post, but I think what is missed is overriding __repr__, so that __repr__ = __str__, which is the accepted answer of this question marked duplicate.

To insert a new row into a given table (tblTable) :

INSERT INTO tblTable (DateColumn) VALUES (GETDATE())

To update an existing row :

UPDATE tblTable SET DateColumn = GETDATE()
 WHERE ID = RequiredUpdateID

Note that when INSERTing a new row you will need to observe any constraints which are on the table - most likely the NOT NULL constraint - so you may need to provide values for other columns eg...

 INSERT INTO tblTable (Name, Type, DateColumn) VALUES ('John', 7, GETDATE())

also you can use this :

    if (! $('#leftmenu').children().length > 0 ) {
         // do something : e.x : remove a specific div
    }

I think it'll work for you !

1. Is it really a .ico, or is it just named ".ico"?
2. What browser are you testing in?

The absolutely easiest way to have a favicon is to place an icon called "favicon.ico" in the root folder. That just works everywhere, no code needed at all.

If you must have it in a subdirectory, use:

<link rel="shortcut icon" href="/img/favicon.ico" />

Note the / before img to ensure it is anchored to the root folder.

Try this

        self.opener.location.reload(); 

Open the parent of a current window and reload the location.

Changing file permissions from Properties, disabling inheritance and running chmod 400 didn't work for me. The permissions for my private key file were:

-r--r----- 1 alex None 1766 Mar 8 13:04 /home/alex/.ssh/id_rsa

Then I noticed the group was None, so I just ran

chown alex:Administrators ~/.ssh/id_rsa

Then I could successfully change the permissions with chmod 400, and run a git push.

If you're using Java 8, you should use the java.time.* classes to compare dates - it's preferred to the various java.util.* classes

eg; https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html

LocalDate date1 = LocalDate.of(2016, 2, 14);
LocalDate date2 = LocalDate.of(2015, 5, 23);
date1.isAfter(date2);

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

This error may be triggered by insufficient memory on RDP server.

A primary key has the semantic of identifying the row of a database. Therefore there can be only one primary key for a given table, while there can be many unique keys.

Also for the same reason a primary key cannot be NULL (at least in Oracle, not sure about other databases)

Since it identifies the row it should never ever change. Changing primary keys are bound to cause serious pain and probably eternal damnation.

Therefor in most cases you want some artificial id for primary key which isn't used for anything but identifying single rows in the table.

Unique keys on the other hand may change as much as you want.

if you don't want .pyc anymore you can use this single line in a terminal:

export PYTHONDONTWRITEBYTECODE=1

if you change your mind:

unset PYTHONDONTWRITEBYTECODE

the string in your question is not a valid json string. From json.org website:

JSON is built on two structures:

* A collection of name/value pairs. In various languages, this is 
  realized as an object, record, struct, dictionary, hash table, keyed list, or
  associative array.
* An ordered list of values. In most languages, this is realized as an
  array, vector, list, or sequence.

Basically a json string will always start with either { or [.

Then as @Andy E and @Cryo said you can parse the string with json2.js or some other libraries.

IMHO you should avoid eval because it will any javascript program, so you might incur in security issues.

The below code stores the return value in to the variable retVal and then MsgBox can be used to display the value:

Dim retVal As Integer
retVal = test()
Msgbox retVal

I don't think there is way out of the box. There is no such command in DOS and batch files are far to limited to simulate it (without major pain).

git reset --hard will force the working directory back to the last commit and delete new/changed files.

It's not exactly clear how you want to search the array. Here are some alternatives:

Find all items containing the exact string "Ra" (returns items 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.Contains("Ra"))

Find all items starting with the exact string "Ra" (returns items 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.StartsWith("Ra"))

Find all items containing any case version of "ra" (returns items 0, 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.ToLower().Contains("ra"))

Find all items starting with any case version of "ra" (retuns items 0, 2 and 3):

Dim result As String() = Array.FindAll(arr, Function(s) s.ToLower().StartsWith("ra"))

-

If you are not using VB 9+ then you don't have anonymous functions, so you have to create a named function.

Example:

Function ContainsRa(s As String) As Boolean
   Return s.Contains("Ra")
End Function

Usage:

Dim result As String() = Array.FindAll(arr, ContainsRa)

Having a function that only can compare to a specific string isn't always very useful, so to be able to specify a string to compare to you would have to put it in a class to have somewhere to store the string:

Public Class ArrayComparer

   Private _compareTo As String

   Public Sub New(compareTo As String)
      _compareTo = compareTo
   End Sub

   Function Contains(s As String) As Boolean
      Return s.Contains(_compareTo)
   End Function

Use your mydate object and call getMonth() and getFullYear()

I discovered the same problem and after reading the first answer that supposed the problem is caused by the window name, changed it : first to '_blank', which worked fine (both compatibility and regular view), then to the previous value, only minus the space in the value :) - also worked. IMO, the problem (or part of it) is caused by IE being unable to use a normal string value as the wname. Hope this helps if anybody runs into the same problem.

Apart from the settings explained in the answer by @DarkNeuron:

"files.encoding": "any encoding"

you can also specify settings for a specific language like so:

"[language id]": {
  "files.encoding": "any encoding"
}

For example, I use this when I need to edit PowerShell files previously created with ISE (which are created in ANSI format):

"[powershell]": {
    "files.encoding": "windows1252"
}

You can get a list of identifiers of well-known languages here.

I'd probably go with this (I know its not pure linq), keep a reference to the original list if you want to retain all items, and you should find the updated values are in there:

 foreach (var mc in list.Where(x => x.Name == "height"))  
     mc.Value = 30;

Configuration Options:

$(document).ready(function () {

  $("#companiesTable").dataTable({
    "sPaginationType": "full_numbers",
    "bJQueryUI": true,
    "bAutoWidth": false, // Disable the auto width calculation 
    "aoColumns": [
      { "sWidth": "30%" }, // 1st column width 
      { "sWidth": "30%" }, // 2nd column width 
      { "sWidth": "40%" } // 3rd column width and so on 
    ]
  });
});

Specify the css for the table:

table.display {
  margin: 0 auto;
  width: 100%;
  clear: both;
  border-collapse: collapse;
  table-layout: fixed;         // add this 
  word-wrap:break-word;        // add this 
}

HTML:

<table id="companiesTable" class="display"> 
  <thead>
    <tr>
      <th>Company name</th>
      <th>Address</th>
      <th>Town</th>
    </tr>
  </thead>
  <tbody>

    <% for(Company c: DataRepository.GetCompanies()){ %>
      <tr>  
        <td><%=c.getName()%></td>
        <td><%=c.getAddress()%></td>
        <td><%=c.getTown()%></td>
      </tr>
    <% } %>

  </tbody>
</table>

It works for me!

Creating a new base collection for each eloquent collection the merge works for me.

$foo = collect(Foo::all());
$bar = collect(Bar::all());
$merged = $foo->merge($bar);

In this case don't have conflits by its primary keys.

I'm somewhat surprised that no one has mentioned that the original poster might have liked rational numbers to result. Should you be interested in this, the Python-based program Sage has your back. (Currently still based on Python 2.x, though 3.x is under way.)

sage: (20-10) / (100-10)
1/9

This isn't a solution for everyone, because it does do some preparsing so these numbers aren't ints, but Sage Integer class elements. Still, worth mentioning as a part of the Python ecosystem.

Try this, it will insert the list item at index 0;

DropDownList1.Items.Insert(0, new ListItem("Add New", ""));

Though you have solved the problem, I just post the reason here for some others with the similar problem.

The reason is there's an space in your path(directory name VirtualBox VMs) which will separate the command. So the error appears.

A FD (functional dependency) that holds in a relation is partial when removing one of the determining attributes gives a FD that holds in the relation. A FD that isn't partial is full.

Eg: If {A,B} ? {C} but also {A} ? {C} then {C} is partially functionally dependent on {A,B}.

Eg: Here's a relation value where that example condition holds. (A FD holds in a relation variable when it holds in every value that can arise.)

A  B  C
1  1  1
1  2  1
2  1  1

The non-trivial FDs that hold: {A,B} determines {C}, {B,C}, {A,C} & {A,B,C}; {A}, {B} & {} also determine {C}. Of those: {A,B} ? {C} is partial per {A} ? {C}, {B} ? {C} & {} ? {C}; {A} ? {C} & {B} ? {C} are partial per {} ? {C}; the others are full.

A functional dependency X ? Y is a full functional dependency if removal of any attribute A from X means that the dependency does not hold any more; that is, for any attribute A e X, (X – {A}) does not functionally determine Y. A functional dependency X ? Y is a partial dependency if some attribute A e X can be removed from X and the dependency still holds; that is, for some A e X, (X – {A}) ? Y.

-- FUNDAMENTALS OF Database Systems SIXTH EDITION Ramez Elmasri & Navathe

Notice that whether a FD is full vs partial doesn't depend on CKs (candidate keys), let alone one CK that you might be calling the PK (primary key).

(A definition of 2NF is that every non-CK attribute is fully functionally determined by every CK. Observe that the only CK is {A,B} & the only non-CK attribute C is partially dependent on it so this value is not in 2NF & indeed it is the lossless join of components/projections onto {A,B} & {A,C}, onto {A,B} & {B,C} & onto {A,B} & {C}.)

(Beware that that textbook's definition of "transitive FD" does not define the same sort of thing as the standard definition of "transitive FD".)

You want java.text.DecimalFormat.

DecimalFormat df = new DecimalFormat("0.00##");
String result = df.format(34.4959);

If you are using an <img> tag for the SVG, then you cannot manipulate its contents (as far as I know).

As the accepted answer shows, using <object> is an option.

I needed this recently and used gulp-inject during my gulp build to inject the contents of an SVG file directly into the HTML document as an <svg> element, which is then very easy to work with using CSS selectors and querySelector/getElementBy*.

When you create a flex container various default flex rules come into play.

Two of these default rules are flex-direction: row and align-items: stretch. This means that flex items will automatically align in a single row, and each item will fill the height of the container.

If you don't want flex items to stretch – i.e., like you wrote:

make its height the minimum required for holding its content

... then simply override the default with align-items: flex-start.

#a {_x000D_
  display: flex;_x000D_
  align-items: flex-start; /* NEW */_x000D_
}_x000D_
#a > div {_x000D_
  background-color: red;_x000D_
  padding: 5px;_x000D_
  margin: 2px;_x000D_
}_x000D_
#b {_x000D_
  height: auto;_x000D_
}

<div id="a">_x000D_
  <div id="b">left</div>_x000D_
  <div>_x000D_
    right<br>right<br>right<br>right<br>right<br>_x000D_
  </div>_x000D_
</div>

Here's an illustration from the flexbox spec that highlights the five values for align-items and how they position flex items within the container. As mentioned before, stretch is the default value.

^{Source: W3C}

I would say you have two options:

1. to get all parent divs styled with 100% height (including body and html)

2. to use absolute positioning for one of the parent divs (for example #content) and then all child divs set to height 100%

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

Border

I believe you can get the border width using .css('border-left-width'). You can also fetch top, right, and bottom and compare them to find the max value. The key here is that you have to specify a specific side.

Padding

See jQuery calculate padding-top as integer in px

Margin

Use the same logic as border or padding.

Alternatively, you could use outerWidth. The pseudo-code should be
margin = (outerWidth(true) - outerWidth(false)) / 2. Note that this only works for finding the margin horizontally. To find the margin vertically, you would need to use outerHeight.

Public Function _
CreateTextArrayFromSourceTexts(ParamArray SourceTexts() As Variant) As String()

    ReDim TargetTextArray(0 To UBound(SourceTexts)) As String
    
    For SourceTextsCellNumber = 0 To UBound(SourceTexts)
        TargetTextArray(SourceTextsCellNumber) = SourceTexts(SourceTextsCellNumber)
    Next SourceTextsCellNumber

    CreateTextArrayFromSourceTexts = TargetTextArray
End Function

Example:

Dim TT() As String
TT = CreateTextArrayFromSourceTexts("hi", "bye", "hi", "bcd", "bYe")

Result:

TT(0)="hi"
TT(1)="bye"
TT(2)="hi"
TT(3)="bcd"
TT(4)="bYe"

Enjoy!

Edit: I removed the duplicatedtexts deleting feature and made the code smaller and easier to use.

Aquamacs:

(set-face-attribute 'default nil :font "Monaco-16" )

From the Emacs Wiki Globally Change the Default Font, it says you can use either of these:

(set-face-attribute 'default nil :font FONT )

(set-frame-font FONT nil t)

Where FONT is something like "Monaco-16", e.g.:

(set-face-attribute 'default nil :font "Monaco-16" )

There was an extra closing parenthesis in the first suggestion on the wiki, which caused an error on startup. I finally noticed the extra closing parenthesis, and I subsequently corrected the suggestion on the wiki. Then both of the suggestions worked for me.

@user1417684 and @chris-foster are right!

excerpt from working code (without error handling):

var SubItemModel = mongoose.model('subitems', SubItemSchema);
var ItemModel    = mongoose.model('items', ItemSchema);

var new_sub_item_model = new SubItemModel(new_sub_item_plain);
new_sub_item_model.save(function (error, new_sub_item) {

  var new_item = new ItemModel(new_item);
  new_item.subitem = new_sub_item._id;
  new_item.save(function (error, new_item) {
    // so this is a valid way to populate via the Model
    // as documented in comments above (here @stack overflow):
    ItemModel.populate(new_item, { path: 'subitem', model: 'subitems' }, function(error, new_item) {
      callback(new_item.toObject());
    });
    // or populate directly on the result object
    new_item.populate('subitem', function(error, new_item) {
      callback(new_item.toObject());
    });
  });

});

Base(Base::UPtr n):next(std::move(n)) {}

should be much better as

Base(Base::UPtr&& n):next(std::forward<Base::UPtr>(n)) {}

and

void setNext(Base::UPtr n)

should be

void setNext(Base::UPtr&& n)

with same body.

And ... what is evt in handle() ??

Um, why not just:

>>>> import os
>>>> os.path.join(dir_name, base_filename + "." + format)

As written, your function accepts only two ranges as arguments.

To allow for a variable number of ranges to be used in the function, you need to declare a ParamArray variant array in your argument list. Then, you can process each of the ranges in the array in turn.

For example,

Function myAdd(Arg1 As Range, ParamArray Args2() As Variant) As Double
    Dim elem As Variant
    Dim i As Long
    For Each elem In Arg1
        myAdd = myAdd + elem.Value
    Next elem
    For i = LBound(Args2) To UBound(Args2)
        For Each elem In Args2(i)
            myAdd = myAdd + elem.Value
        Next elem
    Next i
End Function

This function could then be used in the worksheet to add multiple ranges.

For your function, there is the question of which of the ranges (or cells) that can passed to the function are 'Sessions' and which are 'Customers'.

The easiest case to deal with would be if you decided that the first range is Sessions and any subsequent ranges are Customers.

Function calculateIt(Sessions As Range, ParamArray Customers() As Variant) As Double
    'This function accepts a single Sessions range and one or more Customers
    'ranges
    Dim i As Long
    Dim sessElem As Variant
    Dim custElem As Variant
    For Each sessElem In Sessions
        'do something with sessElem.Value, the value of each
        'cell in the single range Sessions
        Debug.Print "sessElem: " & sessElem.Value
    Next sessElem
    'loop through each of the one or more ranges in Customers()
    For i = LBound(Customers) To UBound(Customers)
        'loop through the cells in the range Customers(i)
        For Each custElem In Customers(i)
            'do something with custElem.Value, the value of
            'each cell in the range Customers(i)
            Debug.Print "custElem: " & custElem.Value
         Next custElem
    Next i
End Function

If you want to include any number of Sessions ranges and any number of Customers range, then you will have to include an argument that will tell the function so that it can separate the Sessions ranges from the Customers range.

This argument could be set up as the first, numeric, argument to the function that would identify how many of the following arguments are Sessions ranges, with the remaining arguments implicitly being Customers ranges. The function's signature would then be:

Function calculateIt(numOfSessionRanges, ParamAray Args() As Variant)

Or it could be a "guard" argument that separates the Sessions ranges from the Customers ranges. Then, your code would have to test each argument to see if it was the guard. The function would look like:

Function calculateIt(ParamArray Args() As Variant)

Perhaps with a call something like:

calculateIt(sessRange1,sessRange2,...,"|",custRange1,custRange2,...)

The program logic might then be along the lines of:

Function calculateIt(ParamArray Args() As Variant) As Double
   ...
   'loop through Args
   IsSessionArg = True
   For i = lbound(Args) to UBound(Args)
       'only need to check for the type of the argument
       If TypeName(Args(i)) = "String" Then
          IsSessionArg = False
       ElseIf IsSessionArg Then
          'process Args(i) as Session range
       Else
          'process Args(i) as Customer range
       End if
   Next i
   calculateIt = <somevalue>
End Function

Just for the sake of delivering the shortest solution, here is mine:

^([1-9]\d?|100)$

working fiddle

Based on Daniel Krizian's comment, you can also use the pretty_breaks function from the scales library, which is imported automatically:

ggplot(dat, aes(x,y)) + geom_point() +
scale_x_continuous(breaks = scales::pretty_breaks(n = 10)) +
scale_y_continuous(breaks = scales::pretty_breaks(n = 10))

All you have to do is insert the number of ticks wanted for n.

A slightly less useful solution (since you have to specify the data variable again), you can use the built-in pretty function:

ggplot(dat, aes(x,y)) + geom_point() +
scale_x_continuous(breaks = pretty(dat$x, n = 10)) +
scale_y_continuous(breaks = pretty(dat$y, n = 10))

it can also be achieved with below code

import re

text = 'how are u? umberella u! u. U. U@ U# u '
print (re.sub (r'[uU] ( [^a-z] )', r' you\1 ', text))

or

print (re.sub (r'[uU] ( [\s!,.?@#] )', r' you\1 ', text))

First off, using the mail() function that comes with PHP is not an optimal solution. It is easily marked as spammed, and you need to set up header to ensure that you are sending HTML emails correctly. As for whether the code snippet will work, it would, but I doubt you will get HTML code inside it correctly without specifying extra headers

I'll suggest you take a look at SwiftMailer, which has HTML support, support for different mime types and SMTP authentication (which is less likely to mark your mail as spam).

Insert a dummy record into one of your databases that has a timestamp Select that record and get value of timestamp. Delete that record. Gets for sure the timezone that the server is using to write data and ignores PHP timezones.

Yes, There is a way to change configuration. If you are on a dedicated server and simply need more SQL connections, you may update the "max pool size" entries in both connection strings by following these instructions:

1. Log into your server using Remote Desktop
2. Open My Computer (Windows - E) and go to C:\inetpub\vhosts[domain]\httpdocs
3. Double click on the web.config file. This may just be listed as web if the file structure is set to hide extensions. This will open up Visual Basic or similar editor.

4. Find your Connection Strings, these will look similar to the examples below :

   "add name="SiteSqlServer" connectionString="server=(local);database=dbname;uid=dbuser;pwd=dbpassword;pooling=true;connection lifetime=120;max pool size=25;""

5.Change the max pool size=X value to the required pool size.

6. Save and close your web.config file.

You can try the following:

private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog fDialog = new OpenFileDialog();
        fDialog.Title = "Select file to be upload";
        fDialog.Filter = "All Files|*.*";
        //  fDialog.Filter = "PDF Files|*.pdf";
        if (fDialog.ShowDialog() == DialogResult.OK)
        {
            textBox1.Text = fDialog.FileName.ToString();
        }
    }

Below is a working code to add a fragment e.g 3 times to a vertical LinearLayout (xNumberLinear). You can change number 3 with any other number or take a number from a spinner!

for (int i = 0; i < 3; i++) {
            LinearLayout linearDummy = new LinearLayout(getActivity());
            linearDummy.setOrientation(LinearLayout.VERTICAL);
            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {

                Toast.makeText(getActivity(), "This function works on newer versions of android", Toast.LENGTH_LONG).show();

            } else {
                linearDummy.setId(View.generateViewId());
            }
            fragmentManager.beginTransaction().add(linearDummy.getId(), new SomeFragment(),"someTag1").commit();

            xNumberLinear.addView(linearDummy);
        }

format supports a percentage floating point precision type:

>>> print "{0:.0%}".format(1./3)
33%

If you don't want integer division, you can import Python3's division from __future__:

>>> from __future__ import division
>>> 1 / 3
0.3333333333333333

# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%

# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%

As for iOS 13.4 the preferredStatusBarStyle method in UINavigationController category will not be called, swizzling seems to be the only option without the need of using a subclass.

Example:

Category header:

@interface UINavigationController (StatusBarStyle)
+ (void)setUseLightStatusBarStyle;
@end

Implementation:

#import "UINavigationController+StatusBarStyle.h"
#import <objc/runtime.h>

@implementation UINavigationController (StatusBarStyle)

void (^swizzle)(Class, SEL, SEL) = ^(Class c, SEL orig, SEL new){
    Method origMethod = class_getInstanceMethod(c, orig);
    Method newMethod = class_getInstanceMethod(c, new);
    if(class_addMethod(c, orig, method_getImplementation(newMethod), method_getTypeEncoding(newMethod)))
        class_replaceMethod(c, new, method_getImplementation(origMethod), method_getTypeEncoding(origMethod));
    else
        method_exchangeImplementations(origMethod, newMethod);
};

+ (void)setUseLightStatusBarStyle {
    swizzle(self.class, @selector(preferredStatusBarStyle), @selector(_light_preferredStatusBarStyle));
}

- (UIStatusBarStyle)_light_preferredStatusBarStyle {
    return UIStatusBarStyleLightContent;
}    
@end

Usage in AppDelegate.h:

#import "UINavigationController+StatusBarStyle.h"

[UINavigationController setUseLightStatusBarStyle];

By design, getRequestURL() gives you the full URL, missing only the query string.

In HttpServletRequest, you can get individual parts of the URI using the methods below:

// Example: http://myhost:8080/people?lastname=Fox&age=30

String uri = request.getScheme() + "://" +   // "http" + "://
             request.getServerName() +       // "myhost"
             ":" +                           // ":"
             request.getServerPort() +       // "8080"
             request.getRequestURI() +       // "/people"
             "?" +                           // "?"
             request.getQueryString();       // "lastname=Fox&age=30"

• .getScheme() will give you "https" if it was a https://domain request.
• .getServerName() gives domain on http(s)://domain.
• .getServerPort() will give you the port.

Use the snippet below:

String uri = request.getScheme() + "://" +
             request.getServerName() + 
             ("http".equals(request.getScheme()) && request.getServerPort() == 80 || "https".equals(request.getScheme()) && request.getServerPort() == 443 ? "" : ":" + request.getServerPort() ) +
             request.getRequestURI() +
            (request.getQueryString() != null ? "?" + request.getQueryString() : "");

This snippet above will get the full URI, hiding the port if the default one was used, and not adding the "?" and the query string if the latter was not provided.

Proxied requests

Note, that if your request passes through a proxy, you need to look at the X-Forwarded-Proto header since the scheme might be altered:

request.getHeader("X-Forwarded-Proto")

Also, a common header is X-Forwarded-For, which show the original request IP instead of the proxys IP.

request.getHeader("X-Forwarded-For")

If you are responsible for the configuration of the proxy/load balancer yourself, you need to ensure that these headers are set upon forwarding.

You can pass the parameter to the setTimeout callback function as:

setTimeout(function, milliseconds, param1, param2, ...)

eg.

function myFunction() {
  setTimeout(alertMsg, 3000, "Hello");
}

function alertMsg(message) {
    alert(message)
}

Try this:

NSDictionary *textAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                [UIColor whiteColor],NSForegroundColorAttributeName,
                                [UIColor whiteColor],NSBackgroundColorAttributeName,nil];
self.navigationController.navigationBar.titleTextAttributes = textAttributes;

The first draft of Selectors Level 4 outlines a way to explicitly set the subject of a selector. This would allow the OP to style the list element with the selector $li > a.active

From Determining the Subject of a Selector:

For example, the following selector represents a list item LI unique child of an ordered list OL:

OL > LI:only-child

However the following one represents an ordered list OL having a unique child, that child being a LI:

$OL > LI:only-child

The structures represented by these two selectors are the same, but the subjects of the selectors are not.

Edit: Given how "drafty" a draft spec can be, it's best to keep tabs on this by checking the CSSWG's page on selectors level 4.

I solve it editing the file bootstrap-datapicker.js.

Look for the text bellow in the file and edit the variable "Format:"

var defaults = $.fn.datepicker.defaults = {
    assumeNearbyYear: false,
    autoclose: false,
    beforeShowDay: $.noop,
    beforeShowMonth: $.noop,
    beforeShowYear: $.noop,
    beforeShowDecade: $.noop,
    beforeShowCentury: $.noop,
    calendarWeeks: false,
    clearBtn: false,
    toggleActive: false,
    daysOfWeekDisabled: [],
    daysOfWeekHighlighted: [],
    datesDisabled: [],
    endDate: Infinity,
    forceParse: true,
    format: 'dd/mm/yyyy',
    keyboardNavigation: true,
    language: 'en',
    minViewMode: 0,
    maxViewMode: 4,
    multidate: false,
    multidateSeparator: ',',
    orientation: "auto",
    rtl: false,
    startDate: -Infinity,
    startView: 0,
    todayBtn: false,
    todayHighlight: false,
    weekStart: 0,
    disableTouchKeyboard: false,
    enableOnReadonly: true,
    showOnFocus: true,
    zIndexOffset: 10,
    container: 'body',
    immediateUpdates: false,
    title: '',
    templates: {
        leftArrow: '«',
        rightArrow: '»'
    }
};

You will need to cast or convert the values to decimal before division. Take a look at this http://msdn.microsoft.com/en-us/library/aa226054.aspx

For example

DECLARE @num1 int = 3 DECLARE @num2 int = 2

SELECT @num1/@num2

SELECT @num1/CONVERT(decimal(4,2), @num2)

The first SELECT will result in what you're seeing while the second SELECT will have the correct answer 1.500000

It's a matter of scope. In short, global variables should be avoided so:

You either need to pass it as a parameter:

$data = 'My data';

function menugen($data)
{
    echo $data;
}

Or have it in a class and access it

class MyClass
{
    private $data = "";

    function menugen()
    {
        echo this->data;
    }

See @MatteoTassinari answer as well, as you can mark it as global to access it, but global variables are generally not required, so it would be wise to re-think your coding.

To include native libraries you need:

1. create "jar" file with special structure containing ".so" files;
2. include that file in dependencies list.

To create jar file, use the following snippet:

task nativeLibsToJar(type: Zip, description: 'create a jar archive of the native libs') {
    destinationDir file("$buildDir/native-libs")
    baseName 'native-libs'
    extension 'jar'
    from fileTree(dir: 'libs', include: '**/*.so')
    into 'lib/'
}

tasks.withType(Compile) {
    compileTask -> compileTask.dependsOn(nativeLibsToJar)
}

To include resulting file, paste the following line into "dependencies" section in "build.gradle" file:

compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')

I tried almost all of these techniques (except FXLabel) and couldn't get any of them to work with iOS 7. I did eventually find THLabel which is working perfectly for me. I used THLabel in Interface Builder and setup User Defined Runtime Attributes so that it's easy for a non programmer to control the look and feel.

As it appears, Graphviz2.37 is known to have problems with the PATH variable on windows. I uninstalled it, removed the environment variables associated with it and instead downloaded and installed the newer beta version 2.39 and it now works like a charm.

Check your short_open_tag setting (use <?php phpinfo() ?> to see its current setting).

Keep it simple...

$intArray = array ();
$strArray = explode(',', $string);
foreach ($strArray as $value)
$intArray [] = intval ($value);

Why are you looking for other ways? Looping does the job without pain. If performance is your concern, you can go with json_decode (). People have posted how to use that, so I am not including it here.

Note: When using == operator instead of === , your string values are automatically converted into numbers (e.g. integer or double) if they form a valid number without quotes. For example:

$str = '1';
($str == 1) // true but
($str === 1) //false

Thus, == may solve your problem, is efficient, but will break if you use === in comparisons.

You need to pass the whole point to location

var point = new Point(50, 100);
this.balancePanel.Location = point;

You just compile it. In the bin\Release (or bin\Debug) folder, the .exe will be in there.

If you're asking how to make an executable which does not rely on the .NET framework at all, then that's a lot harder and you'll need to purchase something like RemoteSoft's Salamader. In general, it's not really worth the bother: Windows Vista comes with .NET framework 2.0 pre-installed already so if you're worried about that, you can just target the 2.0 framework (then only XP users would have to install the framework).

The background-size property is ie>=9 only, but if that is fine with you, you can use a div with background-image and set background-size: contain:

div.image{
    background-image: url("your/url/here");
    background-size: contain;
    background-repeat: no-repeat;
    background-position: center;
}

Now you can just set your div size to whatever you want and not only will the image keep its aspect ratio it will also be centralized both vertically and horizontally within the div. Just don't forget to set the sizes on the css since divs don't have the width/height attribute on the tag itself.

This approach is different than setecs answer, using this the image area will be constant and defined by you (leaving empty spaces either horizontally or vertically depending on the div size and image aspect ratio), while setecs answer will get you a box that exactly the size of the scaled image (without empty spaces).

Edit: According to the MDN background-size documentation you can simulate the background-size property in IE8 using a proprietary filter declaration:

Though Internet Explorer 8 doesn't support the background-size property, it is possible to emulate some of its functionality using the non-standard -ms-filter function:

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='path_relative_to_the_HTML_file', sizingMethod='scale')";

They're different characters. \r is carriage return, and \n is line feed.

On "old" printers, \r sent the print head back to the start of the line, and \n advanced the paper by one line. Both were therefore necessary to start printing on the next line.

Obviously that's somewhat irrelevant now, although depending on the console you may still be able to use \r to move to the start of the line and overwrite the existing text.

More importantly, Unix tends to use \n as a line separator; Windows tends to use \r\n as a line separator and Macs (up to OS 9) used to use \r as the line separator. (Mac OS X is Unix-y, so uses \n instead; there may be some compatibility situations where \r is used instead though.)

For more information, see the Wikipedia newline article.

EDIT: This is language-sensitive. In C# and Java, for example, \n always means Unicode U+000A, which is defined as line feed. In C and C++ the water is somewhat muddier, as the meaning is platform-specific. See comments for details.

Probably embed into your objects an ID "tag" and use it to distinguish between objects of class A and objects of class B.

This however shows a flaw in the design. Ideally those methods in B which A doesn't have, should be part of A but left empty, and B overwrites them. This does away with the class-specific code and is more in the spirit of OOP.

If DAO use

RS.Move 0, RS.LastModified
lngID = RS!AutoNumberFieldName

If ADO use

cn.Execute "INSERT INTO TheTable.....", , adCmdText + adExecuteNoRecords
Set rs = cn.Execute("SELECT @@Identity", , adCmdText)
Debug.Print rs.Fields(0).Value

cn being a valid ADO connection, @@Identity will return the last Identity (Autonumber) inserted on this connection.

Note that @@Identity might be troublesome because the last generated value may not be the one you are interested in. For the Access database engine, consider a VIEW that joins two tables, both of which have the IDENTITY property, and you INSERT INTO the VIEW. For SQL Server, consider if there are triggers that in turn insert records into another table that also has the IDENTITY property.

BTW DMax would not work as if someone else inserts a record just after you've inserted one but before your Dmax function finishes excecuting, then you would get their record.

Interfaces can not be directly instantiated, you should instantiate classes that implements such Interfaces.

Try this:

NameValuePair[] params = new BasicNameValuePair[] {
        new BasicNameValuePair("param1", param1),
        new BasicNameValuePair("param2", param2),
};

You will have to annotate your service with @Service since you have said I am using annotations for mapping

You have declared an array that can store 8 elements not 9.

this.posStatus = new int[8]; 

It means postStatus will contain 8 elements from index 0 to 7.

Call SYS_CONTEXT to get the current schema. From Ask Tom "How to get current schema:

select sys_context( 'userenv', 'current_schema' ) from dual;

As many others have covered, both <br> and <br/> are acceptable.

I guess the tradeoff is the better readability and backward compatibility of <br/> versus sending one less character to the end users with <br>.

And since Google uses <br> so will I.

(Of course keep in mind that they might be serving me <br> because I'm using Chrome which they know supports it. In IE they might still be serving <br/>)

I unable to comment on the top answer, but Excel actually lets you do this without adding the ugly conditional logic.

Conditional formatting is automatically applied to any input that isn't an error, so you can achieve the same effect as:

=NOT(ISERROR(MATCH(A1,$B$1:$B$1000,0)))

With this:

= MATCH(A1,$B$1:$B$1000,0)))

If the above is applied to your data, A1 will be formatted if it matches any cell in $B$1:$B$1000, as any non-match will return an error.

Quite a late, but different answer to the ones already present here:

If instead of $.ajax you'd like to use shorthand functions $.get or $.post, you can pass arrays this way:

Shorthand GET

var array = [1, 2, 3, 4, 5];
$.get('/controller/MyAction', $.param({ data: array }, true), function(data) {});

// Action Method
public void MyAction(List<int> data)
{
    // do stuff here
}

Shorthand POST

var array = [1, 2, 3, 4, 5];
$.post('/controller/MyAction', $.param({ data: array }, true), function(data) {});

// Action Method
[HttpPost]
public void MyAction(List<int> data)
{
    // do stuff here
}

Notes:

• The boolean parameter in $.param is for the traditional property, which MUST be true for this to work.

The dict.pop(key[, default]) method allows you to remove items when you know the key. It returns the value at the key if it removes the item otherwise it returns what is passed as default. See the docs.'

Example:

>>> dic = {'a':1, 'b':2}
>>> dic
{'a': 1, 'b': 2}
>>> dic.pop('c', 0)
0
>>> dic.pop('a', 0)
1
>>> dic
{'b': 2}

Another version of Singleton where the following line of code creates the Singleton instance at the time of application startup.

private static readonly Singleton singleInstance = new Singleton();

Here CLR (Common Language Runtime) will take care of object initialization and thread safety. That means we will not require to write any code explicitly for handling the thread safety for a multithreaded environment.

"The Eager loading in singleton design pattern is nothing a process in which we need to initialize the singleton object at the time of application start-up rather than on demand and keep it ready in memory to be used in future."

public sealed class Singleton
    {
        private static int counter = 0;
        private Singleton()
        {
            counter++;
            Console.WriteLine("Counter Value " + counter.ToString());
        }
        private static readonly Singleton singleInstance = new Singleton(); 

        public static Singleton GetInstance
        {
            get
            {
                return singleInstance;
            }
        }
        public void PrintDetails(string message)
        {
            Console.WriteLine(message);
        }
    }

from main :

static void Main(string[] args)
        {
            Parallel.Invoke(
                () => PrintTeacherDetails(),
                () => PrintStudentdetails()
                );
            Console.ReadLine();
        }
        private static void PrintTeacherDetails()
        {
            Singleton fromTeacher = Singleton.GetInstance;
            fromTeacher.PrintDetails("From Teacher");
        }
        private static void PrintStudentdetails()

            Singleton fromStudent = Singleton.GetInstance;
            fromStudent.PrintDetails("From Student");

Just a little more clarification: A property without 'get','set' won't be able to be bound

I'm facing the case just like the asker's case. And I must have the following things in order for the bind to work properly:

//(1) Declare a property with 'get','set' in code behind
public partial class my_class:Window {
  public String My_Property { get; set; }
  ...

//(2) Initialise the property in constructor of code behind
public partial class my_class:Window {
  ...
  public my_class() {
     My_Property = "my-string-value";
     InitializeComponent();
  }

//(3) Set data context in window xaml and specify a binding
<Window ...
DataContext="{Binding RelativeSource={RelativeSource Self}}">
  <TextBlock Text="{Binding My_Property}"/>
</Window>

"A program doesn't run any faster when it is read from a ".pyc" or ".pyo" file than when it is read from a ".py" file; the only thing that's faster about ".pyc" or ".pyo" files is the speed with which they are loaded. "

Use these two step in console :

git commit --amend -m "new commit message"

and then

git push -f

Done :)

y.tolist().count(val)

with val 0 or 1

Since a python list has a native function count, converting to list before using that function is a simple solution.

If you have an Instance of the EditText available at the point in your code where you want add whitespace, then this code below will work. There may be some things to consider, for example the code below may trigger any TextWatcher you have set to this EditText, idk for sure, just saying, but this will work when trying to append blank space like this: " ", hasn't worked.

messageInputBox.dispatchKeyEvent(new KeyEvent(0, 0, 0, KeyEvent.KEYCODE_SPACE, 0, 0, 0, 0,
                        KeyEvent.KEYCODE_ENDCALL));

Include this line on top of your test class

@PrepareForTest({ First.class })

Although btnMybutton.getBackground().setAlpha(45); is nice idea, it just apply alpha to background and not the whole view.

If you want apply alpha to view use btnMybutton.setAlpha(0.30f); instead. This apply opacity to View. It accepts a value between 0 and 1.

Doc says:

Sets the opacity of the view. This is a value from 0 to 1, where 0 means the view is completely transparent and 1 means the view is completely opaque. If this view overrides onSetAlpha(int) to return true, then this view is responsible for applying the opacity itself. Otherwise, calling this method is equivalent to calling setLayerType(int, android.graphics.Paint) and setting a hardware layer. Note that setting alpha to a translucent value (0 < alpha < 1) may have performance implications. It is generally best to use the alpha property sparingly and transiently, as in the case of fading animations.

Although there are many solutions offered already, I recommend the following two:

1. HTM2PDF - offers an API to convert HTML to PDF and also has a PHP SDK, which makes it very easy to implement in PHP; It offers a choice of server locations in Europe, Asia and the USA
2. PDFmyURL - offers an API that does URL and HTML to PDF as well, with roughly the same functionality as HTM2PDF, but works on a load balanced landscape and has been around a little longer

The thing that's different about these two APIs from all the previously mentioned solutions, is that - besides converting HTML to PDF with CSS and JavaScript - it also offers PDF rights management, watermarking and encryption. Therefore it's an all-in-one solution for those who want to hit the ground running.

Disclaimer: I work for Kaiomi, a company that operates both of these websites.

There's are ambiguities in the question.

What is your input string? Is it the entire file? Or is it 1 line at a time? Some of the answers are assuming the latter. I want to answer the former.

What would you like to return from your regular expression? The fact that you want a true / false on whether a match was made? Or do you want to extract the entire line whose start begins with CTR? I'll answer you only want a true / false match.

To do this, we just need to determine if the CTR occurs at either the start of a file, or immediately following a new line.

/(?:^|\n)CTR/

I like short version: mvn clean install -DskipTests

It's work too: mvn clean install -DskipTests=true

If you absolutely must, you can also use the maven.test.skip property to skip compiling the tests. maven.test.skip is honored by Surefire, Failsafe and the Compiler Plugin. mvn clean install -Dmaven.test.skip=true

and you can add config in maven.xml

<project>
      [...]
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.16</version>
            <configuration>
              <skipTests>true</skipTests>
            </configuration>
          </plugin>
        </plugins>
      </build>
      [...]
    </project>

Usually for jumping people use Rigidbody2D.AddForce with Forcemode.Impulse. It may seem like your object is pushed once in Y axis and it will fall down automatically due to gravity.

Example:

rigidbody2D.AddForce(new Vector2(0, 10), ForceMode2D.Impulse);

If I'm not wrong, both functions are part of your class, you should use it like this:

class MyClass():
    def __init__(self, filename):
        self.filename = filename 

        self.stat1 = None
        self.stat2 = None
        self.stat3 = None
        self.stat4 = None
        self.stat5 = None
        self.parse_file()

    def parse_file(self):
        #do some parsing
        self.stat1 = result_from_parse1
        self.stat2 = result_from_parse2
        self.stat3 = result_from_parse3
        self.stat4 = result_from_parse4
        self.stat5 = result_from_parse5

replace your line:

parse_file() 

with:

self.parse_file()

I realize this question is extremely old, but for anyone looking for a solution specific to PostgreSQL, it's:

CREATE TEMP TABLE tmp_table AS SELECT * FROM original_table LIMIT 0;

Note, the temp table will be put into a schema like pg_temp_3.

This will create a temporary table that will have all of the columns (without indexes) and without the data, however depending on your needs, you may want to then delete the primary key:

ALTER TABLE pg_temp_3.tmp_table DROP COLUMN primary_key;

If the original table doesn't have any data in it to begin with, you can leave off the "LIMIT 0".

Before answering let's add some background, explaining what is this HEAD. since some of the options below will result in detached head

First of all what is HEAD?

HEAD is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD at any given time. (excluding git worktree)

The content of HEAD is stored inside .git/HEAD and it contains the 40 bytes SHA-1 of the current commit.

detached HEAD

If you are not on the latest commit - meaning that HEAD is pointing to a prior commit in history its called detached HEAD.

On the command line, it will look like this- SHA-1 instead of the branch name since the HEAD is not pointing to the tip of the current branch

A few options on how to recover from a detached HEAD:

git checkout

git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back

This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.

# Checkout a given commit. 
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>

# create a new branch forked to the given commit
git checkout -b <branch name>

git reflog

You can always use the reflog as well.
git reflog will display any change which updated the HEAD and checking out the desired reflog entry will set the HEAD back to this commit.

Every time the HEAD is modified there will be a new entry in the reflog

git reflog
git checkout HEAD@{...}

This will get you back to your desired commit

git reset --hard <commit_id>

"Move" your HEAD back to the desired commit.

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.

• Note: (Since Git 2.7)
  you can also use the git rebase --no-autostash as well.

git revert <sha-1>

"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.

# add new commit with the undo of the original one.
# the <sha-1> can be any commit(s) or commit range
git revert <sha-1>

This schema illustrates which command does what.
As you can see there reset && checkout modify the HEAD.

1. Download the latest JDBC Driver (i.e. sqljdbc4.0) from Microsoft's web site

2. Write the program as follows:

   import java.sql.*;
   class testmssql
   {
       public static void main(String args[]) throws Exception
       {
           Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
           Connection      con=DriverManager.getConnection("jdbc:sqlserver://localhost:1433;
                   databaseName=chapter16","sa","123");//repalce your databse name and user name
               Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("Select * from login");//replace your table name
           while(rs.next())
           {
               String s1=rs.getString(1);
               String s2=rs.getString(2);
               System.out.println("UserID:"+s1+"Password:"+s2);
           }
           con.close();
       } 
   }
   

3. Compile the program and set the jar classpath viz: set classpath=C:\jdbc\sqljdbc4.jar;.; If you have saved your jar file in C:\jdbc after downloading and extracting.

4. Run the program and make sure your TCP/IP service is enabled. If not enabled, then follow these steps:
   1. Go to Start -> All Programs -> Microsoft SQL Server 2008 -> Configuration tools -> SQL Server Configuration Manager
   2. Expand Sql Server Network Configuration: choose your MS SQL Server Instance viz. MSQSLSERVER and enable TCP/IP.
   3. Restart your MS SQL Server Instance. This can be done also from the right click menu of Microsoft SQL Server Management Studio at the root level of your MS SQL server instance

There are few examples for using JSONP which include error handling.

However, please note that the error-event is not triggered when using JSONP! See: http://api.jquery.com/jQuery.ajax/ or jQuery ajax request using jsonp error

There's no way to find the maximum / minimum in the general case without looping through all the n elements (if you go from, 1 to n-1, how do you know whether the element n isn't larger (or smaller) than the current max/min)?

You mentioned that the values change every couple of seconds. If you know exactly which values change, you can start with your previous max/min values, and only compare with the new ones, but even in this case, if one of the values which were modified was your old max/min, you may need to loop through them again.

Another alternative - again, only if the number of values which change are small - would be to store the values in a structure such as a tree or a heap, and as the new values arrive you'd insert (or update) them appropriately. But whether you can do that is not clear based on your question.

If you want to get the maximum / minimum element of a given list while looping through all elements, then you can use something like the snippet below, but you will not be able to do that without going through all of them

var list = { "a":4, "b":0.5 , "c":0.35, "d":5 };
var keys = Object.keys(list);
var min = list[keys[0]]; // ignoring case of empty list for conciseness
var max = list[keys[0]];
var i;

for (i = 1; i < keys.length; i++) {
    var value = list[keys[i]];
    if (value < min) min = value;
    if (value > max) max = value;
}

Head First SQL is a great introduction.

If this is for some configuration file processing, consider using Apache configuration. https://commons.apache.org/proper/commons-configuration/javadocs/v1.10/apidocs/index.html?org/apache/commons/configuration/PropertiesConfiguration.html It has way to multiple values to single key- The format is bit different though

key=value1,value2,valu3 gives three values against same key.

Better to use change event on input field.

Updated source:

var myfile="";

$('#resume_link').click(function( e ) {
    e.preventDefault();
    $('#resume').trigger('click');
});

$('#resume').on( 'change', function() {
   myfile= $( this ).val();
   var ext = myfile.split('.').pop();
   if(ext=="pdf" || ext=="docx" || ext=="doc"){
       alert(ext);
   } else{
       alert(ext);
   }
});

Updated jsFiddle.

There are a several things you need to address to get it working

1. The name is wrong its not @ouput its @code
2. You need to set the parameter direction to Output.
3. Don't use AddWithValue since its not supposed to have a value just you Add.
4. Use ExecuteNonQuery if you're not returning rows

Try

SqlParameter output = new SqlParameter("@code", SqlDbType.Int);
output.Direction = ParameterDirection.Output;
cmd.Parameters.Add(output);
cmd.ExecuteNonQuery();
MessageBox.Show(output.Value.ToString());

As far as I know, if an exception is not caught by your script, it will be interrupted.

At first courtesy goes to @Charuka .

DO

You can use android:progressDrawable="@drawable/seekbar" instead of android:background="@drawable/seekbar" .

progressDrawable used for the progress mode.

You should try with

android:minHeight

Defines the minimum height of the view. It is not guaranteed the view will be able to achieve this minimum height (for example, if its parent layout constrains it with less available height).

android:minWidth

Defines the minimum width of the view. It is not guaranteed the view will be able to achieve this minimum width (for example, if its parent layout constrains it with less available width)

    android:minHeight="25p"
    android:maxHeight="25dp" 

FYI:

Using android:minHeight and android:maxHeight is not good solutions .Need to rectify your Custom Seekbar (From Class Level) .

Hi you should try the string split method:

i = "Hello world"
output = i.split()

j = 'is not enough'

print 'The', output[1], j

In addition to David Sacks answer, you may also need to go to the Build tab of the Project Properties and set Platform Target to x86 for the project that is giving you these warnings. Though you might expect it to be, this setting does not seem to be perfectly synchronized with the setting in the configuration manager.

I found the solution after a few tries, I hope this can help you. Add the following to your <ReactTable> component:

getTrProps={(state, rowInfo) => {
  if (rowInfo && rowInfo.row) {
    return {
      onClick: (e) => {
        this.setState({
          selected: rowInfo.index
        })
      },
      style: {
        background: rowInfo.index === this.state.selected ? '#00afec' : 'white',
        color: rowInfo.index === this.state.selected ? 'white' : 'black'
      }
    }
  }else{
    return {}
  }
}

In your state don't forget to add a null selected value, like:

state = { selected: null }

You generally don't want to bloat production package with things that you only intend to use for Development purposes.

Use --save-dev (or -D) option to separate packages such as Unit Test frameworks (jest, jasmine, mocha, chai, etc.)

Any other packages that your app needs for Production, should be installed using --save (or -S).

npm install --save lodash       //prod dependency
npm install -S moment           // "       "
npm install -S opentracing      // "       "

npm install -D jest                 //dev only dependency
npm install --save-dev typescript   //dev only dependency

If you open the package.json file then you will see these entries listed under two different sections:

"dependencies": {
  "lodash": "4.x",
  "moment": "2.x",
  "opentracing": "^0.14.1"
},

"devDependencies": {
    "jest": "22.x",
    "typescript": "^2.8.3"
},

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

Add margin to your div style

margin:0 10px 10px 0;

http://www.w3schools.com/css/css_margin.asp

LinearLayout layout = (LinearLayout)findViewById(R.id.layout);
View child = getLayoutInflater().inflate(R.layout.child, null);
layout.addView(child);

An example usage:

>>> s = 'Hello world'
>>> t = buffer(s, 6, 5)
>>> t
<read-only buffer for 0x10064a4b0, size 5, offset 6 at 0x100634ab0>
>>> print t
world

The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string.

This isn't very useful for short strings like this, but it can be necessary when using large amounts of data. This example uses a mutable bytearray:

>>> s = bytearray(1000000)   # a million zeroed bytes
>>> t = buffer(s, 1)         # slice cuts off the first byte
>>> s[1] = 5                 # set the second element in s
>>> t[0]                     # which is now also the first element in t!
'\x05'

This can be very helpful if you want to have more than one view on the data and don't want to (or can't) hold multiple copies in memory.

Note that buffer has been replaced by the better named memoryview in Python 3, though you can use either in Python 2.7.

Note also that you can't implement a buffer interface for your own objects without delving into the C API, i.e. you can't do it in pure Python.

According to the docs of setState() the new state might not get reflected in the callback function findRoutes(). Here is the extract from React docs:

setState() does not immediately mutate this.state but creates a pending state transition. Accessing this.state after calling this method can potentially return the existing value.

There is no guarantee of synchronous operation of calls to setState and calls may be batched for performance gains.

So here is what I propose you should do. You should pass the new states input in the callback function findRoutes().

handleFormSubmit: function(input){
    // Form Input
    this.setState({
        originId: input.originId,
        destinationId: input.destinationId,
        radius: input.radius,
        search: input.search
    });
    this.findRoutes(input);    // Pass the input here
}

The findRoutes() function should be defined like this:

findRoutes: function(me = this.state) {    // This will accept the input if passed otherwise use this.state
    if (!me.originId || !me.destinationId) {
        alert("findRoutes!");
        return;
    }
    var p1 = new Promise(function(resolve, reject) {
        directionsService.route({
            origin: {'placeId': me.originId},
            destination: {'placeId': me.destinationId},
            travelMode: me.travelMode
        }, function(response, status){
            if (status === google.maps.DirectionsStatus.OK) {
                // me.response = response;
                directionsDisplay.setDirections(response);
                resolve(response);
            } else {
                window.alert('Directions config failed due to ' + status);
            }
        });
    });
    return p1
}

For completion, in ES6 we've got classes (supported at the time of writing this only by latest browsers, but available in Babel, TypeScript and other transpilers)

class Foo {
  constructor(){
    this.a = 5;
    this.b = 6;
    this.c = this.a + this.b;
  }  
}

const foo = new Foo();

You already has this (that's what you entered) parse will parse a date into a giving format and print the full date object (toString).

SOLUTION

The definition of optimal can vary, but here's how to concatenate strings from different rows using regular Transact SQL, which should work fine in Azure.

;WITH Partitioned AS
(
    SELECT 
        ID,
        Name,
        ROW_NUMBER() OVER (PARTITION BY ID ORDER BY Name) AS NameNumber,
        COUNT(*) OVER (PARTITION BY ID) AS NameCount
    FROM dbo.SourceTable
),
Concatenated AS
(
    SELECT 
        ID, 
        CAST(Name AS nvarchar) AS FullName, 
        Name, 
        NameNumber, 
        NameCount 
    FROM Partitioned 
    WHERE NameNumber = 1

    UNION ALL

    SELECT 
        P.ID, 
        CAST(C.FullName + ', ' + P.Name AS nvarchar), 
        P.Name, 
        P.NameNumber, 
        P.NameCount
    FROM Partitioned AS P
        INNER JOIN Concatenated AS C 
                ON P.ID = C.ID 
                AND P.NameNumber = C.NameNumber + 1
)
SELECT 
    ID,
    FullName
FROM Concatenated
WHERE NameNumber = NameCount

EXPLANATION

The approach boils down to three steps:

1. Number the rows using OVER and PARTITION grouping and ordering them as needed for the concatenation. The result is Partitioned CTE. We keep counts of rows in each partition to filter the results later.

2. Using recursive CTE (Concatenated) iterate through the row numbers (NameNumber column) adding Name values to FullName column.

3. Filter out all results but the ones with the highest NameNumber.

Please keep in mind that in order to make this query predictable one has to define both grouping (for example, in your scenario rows with the same ID are concatenated) and sorting (I assumed that you simply sort the string alphabetically before concatenation).

I've quickly tested the solution on SQL Server 2012 with the following data:

INSERT dbo.SourceTable (ID, Name)
VALUES 
(1, 'Matt'),
(1, 'Rocks'),
(2, 'Stylus'),
(3, 'Foo'),
(3, 'Bar'),
(3, 'Baz')

The query result:

ID          FullName
----------- ------------------------------
2           Stylus
3           Bar, Baz, Foo
1           Matt, Rocks

You can make use of java.util.Date with direct date string format:

String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());

1. replace all single quotes with double quotes
2. replace 'u"' from your strings to '"' ... so basically convert internal unicodes to strings before loading the string into json

>> strs = "{u'key':u'val'}"
>> strs = strs.replace("'",'"')
>> json.loads(strs.replace('u"','"'))

supplementing @falsetru's answer : run id in the terminal to get your user_id and group_id

Go the directory/partition where you are facing the challenge. Open terminal, type id then press enter. This will show you your user_id and group_id

then type

chown -R user-id:group-id .

Replace user-id and group-id

. at the end indicates current partition / repository

// chown -R 1001:1001 . (that was my case)

I am heavily tempted to close this as a duplicate; this question appears to be answered in many different ways all over the site:

• will a script in html's script tag with extension php be cached?
• When does browser automatically clear cache of external JavaScript file?
• Help with aggressive JavaScript caching
• How to control web page caching, across all browsers?
• How can I make the browser see CSS and Javascript changes?

First, disable the php5 module:

a2dismod php5

then, enable the php7 module:

a2enmod php7.0

Next, reload/restart the Apache service:

service apache2 restart

Update 2018-09-04

wrt the comment, you need to specify exact installed php-7.x version.

Code definition :

#define roundz(x,d) ((floor(((x)*pow(10,d))+.5))/pow(10,d))

Results :

a = 8.000000
sqrt(a) = r = 2.828427
roundz(r,2) = 2.830000
roundz(r,3) = 2.828000
roundz(r,5) = 2.828430

Use string instead of string? in all places in your code.

The Nullable<T> type requires that T is a non-nullable value type, for example int or DateTime. Reference types like string can already be null. There would be no point in allowing things like Nullable<string> so it is disallowed.

Also if you are using C# 3.0 or later you can simplify your code by using auto-implemented properties:

public class WordAndMeaning
{
    public string Word { get; set; }
    public string Meaning { get; set; }
}

Start in the background:

./long_running_process options &

And disown the job before you log out:

disown

Tried this out quickly in the interactive shell:

>>> l = ['a', 'ab', 'abc', 'bac']
>>> [x for x in l if 'ab' in x]
['ab', 'abc']
>>>

Why does this work? Because the in operator is defined for strings to mean: "is substring of".

Also, you might want to consider writing out the loop as opposed to using the list comprehension syntax used above:

l = ['a', 'ab', 'abc', 'bac']
result = []
for s in l:
   if 'ab' in s:
       result.append(s)

You can get access to the environment variables in either the command line or in the registry.

Command Line

If you want a specific environment variable, then just type the name of it (e.g. PATH), followed by a >, and the filename to write to. The following will dump the PATH environment variable to a file named path.txt.

C:\> PATH > path.txt

Registry Method

The Windows Registry holds all the environment variables, in different places depending on which set you are after. You can use the registry Import/Export commands to shift them into the other PC.

For System Variables:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

For User Variables:

HKEY_CURRENT_USER\Environment

You can use async/await for this. I would explain more, but there's nothing really to it. It's just a regular for loop but I added the await keyword before the construction of your Promise

What I like about this is your Promise can resolve a normal value instead of having a side effect like your code (or other answers here) include. This gives you powers like in The Legend of Zelda: A Link to the Past where you can affect things in both the Light World and the Dark World – ie, you can easily work with data before/after the Promised data is available without having to resort to deeply nested functions, other unwieldy control structures, or stupid IIFEs.

// where DarkWorld is in the scary, unknown future
// where LightWorld is the world we saved from Ganondorf
LightWorld ... await DarkWorld

So here's what that will look like ...

const someProcedure = async n =>_x000D_
  {_x000D_
    for (let i = 0; i < n; i++) {_x000D_
      const t = Math.random() * 1000_x000D_
      const x = await new Promise(r => setTimeout(r, t, i))_x000D_
      console.log (i, x)_x000D_
    }_x000D_
    return 'done'_x000D_
  }_x000D_
_x000D_
someProcedure(10).then(x => console.log(x)) // => Promise_x000D_
// 0 0_x000D_
// 1 1_x000D_
// 2 2_x000D_
// 3 3_x000D_
// 4 4_x000D_
// 5 5_x000D_
// 6 6_x000D_
// 7 7_x000D_
// 8 8_x000D_
// 9 9_x000D_
// done

See how we don't have to deal with that bothersome .then call within our procedure? And async keyword will automatically ensure that a Promise is returned, so we can chain a .then call on the returned value. This sets us up for great success: run the sequence of n Promises, then do something important – like display a success/error message.

Probably the best reason is because 0xfffffffffffffff/15 would give you a horribly wrong answer...

something like:

DELIMITER //

CREATE PROCEDURE alluser()
BEGIN
   SELECT *
   FROM users;
END //

DELIMITER ;

than:

SHOW CREATE PROCEDURE alluser

gives result:

'alluser', 'STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER', 'CREATE DEFINER=`root`@`localhost` PROCEDURE `alluser`()
BEGIN
   SELECT *
   FROM users;
END'

I'm not convinced your algorithm is anything but efficient. It's O(n) and only looks at each character once. You're not gonna get any better than that unless you magically know values before checking them.

I would however initialize the capacity of your StringBuilder to the initial size of the string. I'm guessing your perceived performance problem comes from memory reallocation.

Side note: Checking A-z is not safe. You're including [, \, ], ^, _, and `...

Side note 2: For that extra bit of efficiency, put the comparisons in an order to minimize the number of comparisons. (At worst, you're talking 8 comparisons tho, so don't think too hard.) This changes with your expected input, but one example could be:

if (str[i] >= '0' && str[i] <= 'z' && 
    (str[i] >= 'a' || str[i] <= '9' ||  (str[i] >= 'A' && str[i] <= 'Z') || 
    str[i] == '_') || str[i] == '.')

Side note 3: If for whatever reason you REALLY need this to be fast, a switch statement may be faster. The compiler should create a jump table for you, resulting in only a single comparison:

switch (str[i])
{
    case '0':
    case '1':
    .
    .
    .
    case '.':
        sb.Append(str[i]);
        break;
}

Accesing the Current Route Name in Controller

ie - http://localhost/your_project_name/edit

$request->segment(1);  // edit

( or )

$request->url();  // http://localhost/your_project_name/edit

What about BASE58 encoding the URL? Like for example flickr does.

# note the missing lowercase L and the zero etc.
BASE58 = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ' 
url = ''
while node_id >= 58:
    div, mod = divmod(node_id, 58)
    url = BASE58[mod] + url
    node_id = int(div)

return 'http://short.com/%s' % BASE58[node_id] + url

Turning that back into a number isn't a big deal either.

There is no API method to get a character from the Scanner. You should get the String using scanner.next() and invoke String.charAt(0) method on the returned String.

Scanner reader = new Scanner(System.in);
char c = reader.next().charAt(0);

Just to be safe with whitespaces you could also first call trim() on the string to remove any whitespaces.

Scanner reader = new Scanner(System.in);
char c = reader.next().trim().charAt(0);

<iframe> elements have a load event for that.

How you listen to that event is up to you, but generally the best way is to:

1) create your iframe programatically

It makes sure your load listener is always called by attaching it before the iframe starts loading.

<script>
var iframe = document.createElement('iframe');
iframe.onload = function() { alert('myframe is loaded'); }; // before setting 'src'
iframe.src = '...'; 
document.body.appendChild(iframe); // add it to wherever you need it in the document
</script>

2) inline javascript, is another way that you can use inside your HTML markup.

<script>
function onMyFrameLoad() {
  alert('myframe is loaded');
};
</script>

<iframe id="myframe" src="..." onload="onMyFrameLoad(this)"></iframe>

3) You may also attach the event listener after the element, inside a <script> tag, but keep in mind that in this case, there is a slight chance that the iframe is already loaded by the time you get to adding your listener. Therefore it's possible that it will not be called (e.g. if the iframe is very very fast, or coming from cache).

<iframe id="myframe" src="..."></iframe>

<script>
document.getElementById('myframe').onload = function() {
  alert('myframe is loaded');
};
</script>

Also see my other answer about which elements can also fire this type of load event

When you do echo $array;, PHP will simply echo 'Array' since it can't convert an array to a string. So The 'A' that you are actually getting is the first letter of Array, which is correct.

You might actually need

echo json_encode($array);

This should get you what you want.

EDIT : And obviously, you'd need to change your JS to work with JSON instead of just text (as pointed out by @genesis)

If you just want the button to have different styling while the mouse is pressed you can use the :active pseudo class.

.button:active {
}

If on the other hand you want the style to stay after clicking you will have to use javascript.

If SUDO or apt-get is not accessible inside the Container, You can use, below option in running container.

docker exec -u root -it f83b5c5bf413 ash

"f83b5c5bf413" is my container ID & here is working example from my terminal:

Executable file needs a main function. See below hello world demo.

#include <stdio.h>
int main(void)
{
        printf("Hello world!\n");
        return 0;
}

As you can see there is a main function. if you don't have this main function, ld will report "undefined reference to main' "

check my result:

$ cat es3.c
#include <stdio.h>
int main(void)
{
    printf("Hello world!\n");
    return 0;
}
$ gcc -Wall -g -c es3.c
$ gcc -Wall -g es3.o -o es3
~$ ./es3
Hello world! 

please use $ objdump -t es3.o to check if there is a main symbol. Below is my result.

$ objdump -t es3.o

es3.o:     file format elf32-i386

Another way of doing it:

DateTime today = DateTime.Today;
DateTime endOfMonth = new DateTime(today.Year, 
                                   today.Month, 
                                   DateTime.DaysInMonth(today.Year, 
                                                        today.Month));

If it IS a foreach loop as you have described in the question, using $key => $value is fast and efficient.

You probably want to try something like this:

command = "cmd.exe /C dir C:\\"

I don't think you can pipe into cmd.exe... If you are coming from a unix background, well, cmd.exe has some ugly warts!

EDIT: According to Sven Marnach, you can pipe to cmd.exe. I tried following in a python shell:

>>> import subprocess
>>> proc = subprocess.Popen('cmd.exe', stdin = subprocess.PIPE, stdout = subprocess.PIPE)
>>> stdout, stderr = proc.communicate('dir c:\\')
>>> stdout
'Microsoft Windows [Version 6.1.7600]\r\nCopyright (c) 2009 Microsoft Corporatio
n.  All rights reserved.\r\n\r\nC:\\Python25>More? '

As you can see, you still have a bit of work to do (only the first line is returned), but you might be able to get this to work...

For windows just type:

python -m pip --version

window.getSelection - vs - document.selection

This one works for me:

function getCaretCharOffset(element) {_x000D_
  var caretOffset = 0;_x000D_
_x000D_
  if (window.getSelection) {_x000D_
    var range = window.getSelection().getRangeAt(0);_x000D_
    var preCaretRange = range.cloneRange();_x000D_
    preCaretRange.selectNodeContents(element);_x000D_
    preCaretRange.setEnd(range.endContainer, range.endOffset);_x000D_
    caretOffset = preCaretRange.toString().length;_x000D_
  } _x000D_
_x000D_
  else if (document.selection && document.selection.type != "Control") {_x000D_
    var textRange = document.selection.createRange();_x000D_
    var preCaretTextRange = document.body.createTextRange();_x000D_
    preCaretTextRange.moveToElementText(element);_x000D_
    preCaretTextRange.setEndPoint("EndToEnd", textRange);_x000D_
    caretOffset = preCaretTextRange.text.length;_x000D_
  }_x000D_
_x000D_
  return caretOffset;_x000D_
}_x000D_
_x000D_
_x000D_
// Demo:_x000D_
var elm = document.querySelector('[contenteditable]');_x000D_
elm.addEventListener('click', printCaretPosition)_x000D_
elm.addEventListener('keydown', printCaretPosition)_x000D_
_x000D_
function printCaretPosition(){_x000D_
  console.log( getCaretCharOffset(elm), 'length:', this.textContent.trim().length )_x000D_
}

<div contenteditable>some text here <i>italic text here</i> some other text here <b>bold text here</b> end of text</div>

The calling line depends on event type, for key event use this:

getCaretCharOffsetInDiv(e.target) + ($(window.getSelection().getRangeAt(0).startContainer.parentNode).index());

for mouse event use this:

getCaretCharOffsetInDiv(e.target.parentElement) + ($(e.target).index())

on these two cases I take care for break lines by adding the target index

I am in a corporate setting and was attempting a simple git pull after a recent change in password.

I got: remote: Invalid username or password.

Interestingly, the following did not work: git config --global --unset credential.helper

I use Windows-7, so, I went to control panel -> Credential Manager -> Generic Credentials.

From the credential manager list, delete the line items corresponding to git.

After the deletion, come back to gitbash and git pull should prompt the dialog for you to enter your credentials.

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

Here's the answer

Steps to follow:

1. Open the Visual Basic Editor. In Excel, hit Alt+F11 if on Windows, Fn+Option+F11 if on a Mac.

2. Insert a new module. From the menu: Insert -> Module (Don't skip this!).

3. Create a Public function. Example:

   Public Function findArea(ByVal width as Double, _
                            ByVal height as Double) As Double
       ' Return the area
       findArea = width * height
   End Function
   

4. Then use it in any cell like you would any other function: =findArea(B12,C12).

iam using this simple approach

String to Int:

 var a = Int()
var string1 = String("1")
a = string1.toInt()

and from Int to String:

var a = Int()
a = 1
var string1 = String()
 string1= "\(a)"

Here is my solution, there is no way to use momemt.js.Here is DataTable with Two DatePickers for DateRange (To and From) Filter.

$.fn.dataTable.ext.search.push(
  function (settings, data, dataIndex) {
    var min = $('#min').datepicker("getDate");
    var max = $('#max').datepicker("getDate");
    var startDate = new Date(data[4]);
    if (min == null && max == null) { return true; }
    if (min == null && startDate <= max) { return true; }
    if (max == null && startDate >= min) { return true; }
    if (startDate <= max && startDate >= min) { return true; }
    return false;
  }
);
  

    

I have two demos, one with jQuery and one without. Neither use date functions and are about as simple as it gets.

Demo with vanilla JavaScript

function startTimer(duration, display) {_x000D_
    var timer = duration, minutes, seconds;_x000D_
    setInterval(function () {_x000D_
        minutes = parseInt(timer / 60, 10);_x000D_
        seconds = parseInt(timer % 60, 10);_x000D_
_x000D_
        minutes = minutes < 10 ? "0" + minutes : minutes;_x000D_
        seconds = seconds < 10 ? "0" + seconds : seconds;_x000D_
_x000D_
        display.textContent = minutes + ":" + seconds;_x000D_
_x000D_
        if (--timer < 0) {_x000D_
            timer = duration;_x000D_
        }_x000D_
    }, 1000);_x000D_
}_x000D_
_x000D_
window.onload = function () {_x000D_
    var fiveMinutes = 60 * 5,_x000D_
        display = document.querySelector('#time');_x000D_
    startTimer(fiveMinutes, display);_x000D_
};

<body>_x000D_
    <div>Registration closes in <span id="time">05:00</span> minutes!</div>_x000D_
</body>

Demo with jQuery

function startTimer(duration, display) {
    var timer = duration, minutes, seconds;
    setInterval(function () {
        minutes = parseInt(timer / 60, 10);
        seconds = parseInt(timer % 60, 10);

        minutes = minutes < 10 ? "0" + minutes : minutes;
        seconds = seconds < 10 ? "0" + seconds : seconds;

        display.text(minutes + ":" + seconds);

        if (--timer < 0) {
            timer = duration;
        }
    }, 1000);
}

jQuery(function ($) {
    var fiveMinutes = 60 * 5,
        display = $('#time');
    startTimer(fiveMinutes, display);
});

However if you want a more accurate timer that is only slightly more complicated:

function startTimer(duration, display) {_x000D_
    var start = Date.now(),_x000D_
        diff,_x000D_
        minutes,_x000D_
        seconds;_x000D_
    function timer() {_x000D_
        // get the number of seconds that have elapsed since _x000D_
        // startTimer() was called_x000D_
        diff = duration - (((Date.now() - start) / 1000) | 0);_x000D_
_x000D_
        // does the same job as parseInt truncates the float_x000D_
        minutes = (diff / 60) | 0;_x000D_
        seconds = (diff % 60) | 0;_x000D_
_x000D_
        minutes = minutes < 10 ? "0" + minutes : minutes;_x000D_
        seconds = seconds < 10 ? "0" + seconds : seconds;_x000D_
_x000D_
        display.textContent = minutes + ":" + seconds; _x000D_
_x000D_
        if (diff <= 0) {_x000D_
            // add one second so that the count down starts at the full duration_x000D_
            // example 05:00 not 04:59_x000D_
            start = Date.now() + 1000;_x000D_
        }_x000D_
    };_x000D_
    // we don't want to wait a full second before the timer starts_x000D_
    timer();_x000D_
    setInterval(timer, 1000);_x000D_
}_x000D_
_x000D_
window.onload = function () {_x000D_
    var fiveMinutes = 60 * 5,_x000D_
        display = document.querySelector('#time');_x000D_
    startTimer(fiveMinutes, display);_x000D_
};

<body>_x000D_
    <div>Registration closes in <span id="time"></span> minutes!</div>_x000D_
</body>

Now that we have made a few pretty simple timers we can start to think about re-usability and separating concerns. We can do this by asking "what should a count down timer do?"

• Should a count down timer count down? Yes
• Should a count down timer know how to display itself on the DOM? No
• Should a count down timer know to restart itself when it reaches 0? No
• Should a count down timer provide a way for a client to access how much time is left? Yes

So with these things in mind lets write a better (but still very simple) CountDownTimer

function CountDownTimer(duration, granularity) {
  this.duration = duration;
  this.granularity = granularity || 1000;
  this.tickFtns = [];
  this.running = false;
}

CountDownTimer.prototype.start = function() {
  if (this.running) {
    return;
  }
  this.running = true;
  var start = Date.now(),
      that = this,
      diff, obj;

  (function timer() {
    diff = that.duration - (((Date.now() - start) / 1000) | 0);

    if (diff > 0) {
      setTimeout(timer, that.granularity);
    } else {
      diff = 0;
      that.running = false;
    }

    obj = CountDownTimer.parse(diff);
    that.tickFtns.forEach(function(ftn) {
      ftn.call(this, obj.minutes, obj.seconds);
    }, that);
  }());
};

CountDownTimer.prototype.onTick = function(ftn) {
  if (typeof ftn === 'function') {
    this.tickFtns.push(ftn);
  }
  return this;
};

CountDownTimer.prototype.expired = function() {
  return !this.running;
};

CountDownTimer.parse = function(seconds) {
  return {
    'minutes': (seconds / 60) | 0,
    'seconds': (seconds % 60) | 0
  };
};

So why is this implementation better than the others? Here are some examples of what you can do with it. Note that all but the first example can't be achieved by the startTimer functions.

An example that displays the time in XX:XX format and restarts after reaching 00:00

An example that displays the time in two different formats

An example that has two different timers and only one restarts

An example that starts the count down timer when a button is pressed

Direct answer:

• Use a = operator

We can use the public member function std::vector::operator= of the container std::vector for assigning values from a vector to another.

• Use a constructor function

Besides, a constructor function also makes sense. A constructor function with another vector as parameter(e.g. x) constructs a container with a copy of each of the elements in x , in the same order.

Caution:

• Do not use std::vector::swap

std::vector::swap is not copying a vector to another, it is actually swapping elements of two vectors, just as its name suggests. In other words, the source vector to copy from is modified after std::vector::swap is called, which is probably not what you are expected.

• Deep or shallow copy?

If the elements in the source vector are pointers to other data, then a deep copy is wanted sometimes.

According to wikipedia:

A deep copy, meaning that fields are dereferenced: rather than references to objects being copied, new copy objects are created for any referenced objects, and references to these placed in B.

Actually, there is no currently a built-in way in C++ to do a deep copy. All of the ways mentioned above are shallow. If a deep copy is necessary, you can traverse a vector and make copy of the references manually. Alternatively, an iterator can be considered for traversing. Discussion on iterator is beyond this question.

Save your python file in a spot where you will be able to find it again. Then navigate to that spot using the command line (cd /home/[profile]/spot/you/saved/file) or go to that location with the file browser. If you use the latter, right click and select "Open In Terminal." When the terminal opens, type "sudo chmod +x Yourfilename." After entering your password, type "python ./Yourfilename" which will open your python file in the command line. Hope this helps!

Running Linux Mint

I don't try changing sequence via setval. But using ALTER I was issued how to write sequence name properly. And this only work for me:

1. Check required sequence name using SELECT * FROM information_schema.sequences;

2. ALTER SEQUENCE public."table_name_Id_seq" restart {number};

   In my case it was ALTER SEQUENCE public."Services_Id_seq" restart 8;

Also there is a page on wiki.postgresql.org where describes a way to generate sql script to fix sequences in all database tables at once. Below the text from link:

Save this to a file, say 'reset.sql'

SELECT 'SELECT SETVAL(' ||
       quote_literal(quote_ident(PGT.schemaname) || '.' || quote_ident(S.relname)) ||
       ', COALESCE(MAX(' ||quote_ident(C.attname)|| '), 1) ) FROM ' ||
       quote_ident(PGT.schemaname)|| '.'||quote_ident(T.relname)|| ';'
FROM pg_class AS S,
     pg_depend AS D,
     pg_class AS T,
     pg_attribute AS C,
     pg_tables AS PGT
WHERE S.relkind = 'S'
    AND S.oid = D.objid
    AND D.refobjid = T.oid
    AND D.refobjid = C.attrelid
    AND D.refobjsubid = C.attnum
    AND T.relname = PGT.tablename
ORDER BY S.relname;

Run the file and save its output in a way that doesn't include the usual headers, then run that output. Example:

psql -Atq -f reset.sql -o temp
psql -f temp
rm temp

And the output will be a set of sql commands which look exactly like this:

SELECT SETVAL('public."SocialMentionEvents_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."SocialMentionEvents";
SELECT SETVAL('public."Users_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."Users";

I just had the same issue. And i experienced that it always happens when i run the programm and change some code without finishing the programm still running. After that the "cannot open ..." message appears.

However i got rid of it by clicking the "Terminate" button at the very top-right side of the console window (red button) and after that "remove all terminated launches" (two x'es right next to the terminate button). This seems to close the running programm and everything works fine after :) hope this may help anyone

Yes, it's called next.

for i in 0..5
   if i < 2
     next
   end
   puts "Value of local variable is #{i}"
end

This outputs the following:

Value of local variable is 2
Value of local variable is 3
Value of local variable is 4
Value of local variable is 5
 => 0..5 

For any number validation you have to use different different range validation as per your requirements :

For Integer

[Range(0, int.MaxValue, ErrorMessage = "Please enter valid integer Number")]

for float

[Range(0, float.MaxValue, ErrorMessage = "Please enter valid float Number")]

for double

[Range(0, double.MaxValue, ErrorMessage = "Please enter valid doubleNumber")]

Though it is marked as resolved here my KOTLIN RESOLUTION

fun log(properties: Map<String, Any>) {
    val propertyPairsList = properties.map { Pair(it.key, it.value) }
    val bundle = bundleOf(*propertyPairsList.toTypedArray())
}

bundleOf has vararg parameter

Well, you can't add styling using pseudo selectors like :hover, :after, :nth-child, or anything like that using jQuery.

If you want to add a CSS rule like that you have to create a <style> element and add that :hover rule to it just like you would in CSS. Then you would have to add that <style> element to the page.

Using the .hover function seems to be more appropriate if you can't just add the css to a stylesheet, but if you insist you can do:

$('head').append('<style>.myclass:hover div {background-color : red;}</style>')

If you want to read more on adding CSS with javascript you can check out one of David Walsh's Blog posts.

Expanding on the accepted answer:

function mysql_query_or_die($query) {
    $result = mysql_query($query);
    if ($result)
        return $result;
    else {
        $err = mysql_error();
        die("<br>{$query}<br>*** {$err} ***<br>");
    }
}

...
$query = "SELECT * FROM my_table";
$result = mysql_query_or_die($query);
echo("<table>");
$first_row = true;
while ($row = mysql_fetch_assoc($result)) {
    if ($first_row) {
        $first_row = false;
        // Output header row from keys.
        echo '<tr>';
        foreach($row as $key => $field) {
            echo '<th>' . htmlspecialchars($key) . '</th>';
        }
        echo '</tr>';
    }
    echo '<tr>';
    foreach($row as $key => $field) {
        echo '<td>' . htmlspecialchars($field) . '</td>';
    }
    echo '</tr>';
}
echo("</table>");

Benefits:

• Using mysql_fetch_assoc (instead of mysql_fetch_array with no 2nd parameter to specify type), we avoid getting each field twice, once for a numeric index (0, 1, 2, ..), and a second time for the associative key.

• Shows field names as a header row of table.

• Shows how to get both column name ($key) and value ($field) for each field, as iterate over the fields of a row.

• Wrapped in <table> so displays properly.

• (OPTIONAL) dies with display of query string and mysql_error, if query fails.

Example Output:

Id      Name
777     Aardvark
50      Lion
9999    Zebra

A good example of this casting is using *= or /=

byte b = 10;
b *= 5.7;
System.out.println(b); // prints 57

or

byte b = 100;
b /= 2.5;
System.out.println(b); // prints 40

or

char ch = '0';
ch *= 1.1;
System.out.println(ch); // prints '4'

or

char ch = 'A';
ch *= 1.5;
System.out.println(ch); // prints 'a'

I am having the same problem, I found the below on the web somewhere....

Event handlers in Docs are a little tricky though. Because docs can handle multiple simultaneous edits by multiple users, the event handlers are handled server-side. The major issue with this structure is that when an event trigger script fails, it fails on the server. If you want to see the debug info you'll need to setup an explicit trigger under the triggers menu that emails you the debug info when the event fails or else it will fail silently.

Recently I was playing with this method too. I wrote a memoized algorithm to calcualte Fibonacci numbers which could serve as another illustration on how to use the method.

We can start by defining a map and putting the values in it for the base cases, namely, fibonnaci(0) and fibonacci(1):

private static Map<Integer,Long> memo = new HashMap<>();
static {
   memo.put(0,0L); //fibonacci(0)
   memo.put(1,1L); //fibonacci(1)
}

And for the inductive step all we have to do is redefine our Fibonacci function as follows:

public static long fibonacci(int x) {
   return memo.computeIfAbsent(x, n -> fibonacci(n-2) + fibonacci(n-1));
}

As you can see, the method computeIfAbsent will use the provided lambda expression to calculate the Fibonacci number when the number is not present in the map. This represents a significant improvement over the traditional, tree recursive algorithm.

Every class has a nil? method:

if a_variable.nil?
    # the variable has a nil value
end

And strings have the empty? method:

if a_string.empty?
    # the string is empty
}

Remember that a string does not equal nil when it is empty, so use the empty? method to check if a string is empty.

I know the OP is asking for a mysql answer but since I found the other answers not working for me,

• Most of them fail with order by
• Or they are simply very inefficient and make your query very slow for a fat table

So to save time for others like me, just index the row after retrieving them from database

example in PHP:

$users = UserRepository::loadAllUsersAndSortByScore();

foreach($users as $index=>&$user){
    $user['rank'] = $index+1;
}

example in PHP using offset and limit for paging:

$limit = 20; //page size
$offset = 3; //page number

$users = UserRepository::loadAllUsersAndSortByScore();

foreach($users as $index=>&$user){
    $user['rank'] = $index+1+($limit*($offset-1));
}

Better solution is to introduce another interface for async operations. New interface must inherit from original interface.

Example:

interface IIO
{
    void DoOperation();
}

interface IIOAsync : IIO
{
    Task DoOperationAsync();
}


class ClsAsync : IIOAsync
{
    public void DoOperation()
    {
        DoOperationAsync().GetAwaiter().GetResult();
    }

    public async Task DoOperationAsync()
    {
        //just an async code demo
        await Task.Delay(1000);
    }
}


class Program
{
    static void Main(string[] args)
    {
        IIOAsync asAsync = new ClsAsync();
        IIO asSync = asAsync;

        Console.WriteLine(DateTime.Now.Second);

        asAsync.DoOperation();
        Console.WriteLine("After call to sync func using Async iface: {0}", 
            DateTime.Now.Second);

        asAsync.DoOperationAsync().GetAwaiter().GetResult();
        Console.WriteLine("After call to async func using Async iface: {0}", 
            DateTime.Now.Second);

        asSync.DoOperation();
        Console.WriteLine("After call to sync func using Sync iface: {0}", 
            DateTime.Now.Second);

        Console.ReadKey(true);
    }
}

P.S. Redesign your async operations so they return Task instead of void, unless you really must return void.

I have an S3 and used this guide from Google:

https://developers.google.com/chrome-developer-tools/docs/remote-debugging

Really easy, works flawlessly.

All of the examples here (with the exception of rockacola's) require that the user physically click on the window to define focus. This isn't ideal, so .hover() is the better choice:

$(window).hover(function(event) {
    if (event.fromElement) {
        console.log("inactive");
    } else {
        console.log("active");
    }
});

This'll tell you when the user has their mouse on the screen, though it still won't tell you if it's in the foreground with the user's mouse elsewhere.

lines = bigstring.split('\n')
lines = [line for line in lines if line.strip()]

In Java 8, you can read a whole file, simply with:

public String read(String file) throws IOException {
  return new String(Files.readAllBytes(Paths.get(file)));
}

or if its a Resource:

public String read(String file) throws IOException {
  URL url = Resources.getResource(file);
  return Resources.toString(url, Charsets.UTF_8);
}
