Just a few suggestions:

• Screenshots might be an easy way, but you'll have to make sure the code in the image is big enough and clear enough to read. (not the whole screenshot, just the relevant part)
• If you can embed html then there are lots of tools to generate syntax highlighted html.

The newline character (\n) can be used to add a newline into a markdown file programmatically. For example, it is possible to do like this in python:

with open("file_name.md", "w") as file:
   file.write("Some text")
   file.write("\n")
   file.write("Some other text")

I found using

net start postgres_service_name

the only reliable way to operate Postgres on Windows

This is what matplotlib.pyplot.scatter is for.

As a quick example:

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
t = np.linspace(0, 2 * np.pi, 20)
x = np.sin(t)
y = np.cos(t)

plt.scatter(t,x,c=y)
plt.show()

I found another way to do the type.

if(listAxu.size() > 0){
    Collections.sort(listAxu, Comparator.comparing(IdentityNamed::getDescricao));
}

jQuery has a toggleClass function:

<button class="switch">Click me</button>

<div class="text-block collapsed pressed">some text</div>

<script>    
    $('.switch').on('click', function(e) {
      $('.text-block').toggleClass("collapsed pressed"); //you can list several class names 
      e.preventDefault();
    });
</script>

This worked for me:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>2.7.0</version>
</dependency>

Update

As @Jasper suggested, in order to avoid depending on the entire EclipseLink library, you can also just depend on EclipseLink MOXy:

Maven

<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>org.eclipse.persistence.moxy</artifactId>
    <version>2.7.3</version>
</dependency>

Gradle

compile group: 'org.eclipse.persistence', name: 'org.eclipse.persistence.moxy', version: '2.7.3'

As dependencies for my Java 8 app, which produces a *.jar which can be run by both JRE 8 or JRE 9 with no additional arguments.

In addition, this needs to be executed somewhere before JAXB API will be used:

System.setProperty("javax.xml.bind.JAXBContextFactory", "org.eclipse.persistence.jaxb.JAXBContextFactory");

Works great so far, as a workaround. Doesn't look like a perfect solution though...

here, 2 in binary(8 bit) is 00000010 and its 1's complement is 11111101, subtract 1 from that 1's complement we get 11111101-1 = 11111100, here the sign is - as 8th character (from R to L) is 1 find 1's complement of that no. i.e. 00000011 = 3 and the sign is negative that's why we get -3 here.

You can get an idea, how to implement an efficient one, if you don't have any in the library, from here

It use a table for all 256 chars.

• in that table for all chars, except letters - used its ascii codes.
• for upper case letter codes - the table list codes of lower cased symbols.

then we just need to traverse a strings and compare our table cells for a given chars:

const char *cm = charmap,
        *us1 = (const char *)s1,
        *us2 = (const char *)s2;
while (cm[*us1] == cm[*us2++])
    if (*us1++ == '\0')
        return (0);
return (cm[*us1] - cm[*--us2]);

Ad hoc queries are those that are not already defined that are not needed on a regular basis, so they're not included in the typical set of reports or queries

Other answers work, but

To get the full/default price:

$product->get_price_html();

In my case one of the projects contains multiple IDL files. The MIDL compiler generates a DLL data file called 'dlldata.c' for each of them, regardless of the IDL file name. This caused Visual Studio to compile the IDL files on every build, even without changes to any of the IDL files.

The workaround is to configure a unique output file for each IDL file (the MIDL compiler always generates such a file, even if the /dlldata switch is omitted):

• Right-click the IDL file
• Select Properties - MIDL - Output
• Enter a unique file name for the DllData File property

Installing vc_redist.x86.exe works for me even though you have a 64-bit machine.

1. Download the "google-service.json" file from Firebase
2. Go to this address in windows explorer "C:\Users\Your-Username\AndroidStudioProjects" You will see a list of your Android Studio projects
3. Open a desired project, navigate to "app" folder and paste the .json file
4. Go to Android Studio and click on "Sync with file system", located in dropdown menu (File>Sync with file system)
5. Now sync with Gradle and everything should be fine

Let's say you have already set up your origin as the remote repository. Then,

git diff <local branch> <origin>/<remote branch name>

In symfony >= 3.2, documentation states that:

An alternative way to get the current user in a controller is to type-hint the controller argument with UserInterface (and default it to null if being logged-in is optional):

use Symfony\Component\Security\Core\User\UserInterface\UserInterface;

public function indexAction(UserInterface $user = null)
{
    // $user is null when not logged-in or anon.
}

This is only recommended for experienced developers who don't extend from the Symfony base controller and don't use the ControllerTrait either. Otherwise, it's recommended to keep using the getUser() shortcut.

Blog post about it

According to the Swift 2.2 Book published by apple:

“You indicate type methods by writing the static keyword before the method’s func keyword. Classes may also use the class keyword to allow subclasses to override the superclass’s implementation of that method.”

If you're fetching data using Wordpress, then you can access the number of rows returned using $wpdb->num_rows:

$wpdb->get_results( $wpdb->prepare('select * from mytable where foo = %s', $searchstring));
echo $wpdb->num_rows;

If you want a specific count based on a mysql count query then you do this:

$numrows = $wpdb->get_var($wpdb->prepare('SELECT COUNT(*) FROM mytable where foo = %s', $searchstring );
echo $numrows;

If you're running updates or deletes then the count of rows affected is returned directly from the function call:

$numrowsaffected = $wpdb->query($wpdb->prepare(
   'update mytable set val=%s where myid = %d', $valuetoupdate, $myid));

This applies also to $wpdb->update and $wpdb->delete.

In Linux there are two space 1st is user space and another one is kernal space. user space consist of only user application which u want to run. as the kernal service there is process management, file management, signal handling, memory management, thread management, and so many services are present there. if u run the application from the user space that appliction interact with only kernal service. and that service is interact with device driver which is present between hardware and kernal. the main benefit of kernal space and user space seperation is we can acchive a security by the virus.bcaz of all user application present in user space, and service is present in kernal space. thats why linux doesn,t affect from the virus.

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".

    /// <summary>
    /// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not 
    /// let the JsonProperty control everything.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
    {
        private Dictionary<string, string> PropertyMappings { get; set; }

        public IgnoreJsonPropertyResolver()
        {
            this.PropertyMappings = new Dictionary<string, string>();
            var properties = ReflectionHelper<T>.GetGetProperties(false)();
            foreach (var propertyInfo in properties)
            {
                var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
                if (jsonProperty != null)
                {
                    PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
                }
            }
        }

        protected override string ResolvePropertyName(string propertyName)
        {
            string resolvedName = null;
            var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
            return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
        }
    }

Usage:

        var settings = new JsonSerializerSettings();
        settings.DateFormatString = "YYYY-MM-DD";
        settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
        var model = new PlanViewModel() {Amount = 100};
        var strModel = JsonConvert.SerializeObject(model,settings);

Model:

public class PlanViewModel
{

    /// <summary>
    ///     The customer is charged an amount over an interval for the subscription.
    /// </summary>
    [JsonProperty(PropertyName = "RecurringPrice")]
    public double Amount { get; set; }

    /// <summary>
    ///     Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
    ///     months or years depending on the value for interval_unit.
    /// </summary>
    public int Interval { get; set; } = 1;

    /// <summary>
    ///     Number of free trial days that can be granted when a customer is subscribed to this plan.
    /// </summary>
    public int TrialPeriod { get; set; } = 30;

    /// <summary>
    /// This indicates a one-time fee charged upfront while creating a subscription for this plan.
    /// </summary>
    [JsonProperty(PropertyName = "SetupFee")]
    public double SetupAmount { get; set; } = 0;


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "TypeId")]
    public string Type { get; set; }

    /// <summary>
    /// Billing Frequency
    /// </summary>
    [JsonProperty(PropertyName = "BillingFrequency")]
    public string Period { get; set; }


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "PlanUseType")]
    public string Purpose { get; set; }
}

The volatile and transient modifiers can be applied to fields of classes¹ irrespective of field type. Apart from that, they are unrelated.

The transient modifier tells the Java object serialization subsystem to exclude the field when serializing an instance of the class. When the object is then deserialized, the field will be initialized to the default value; i.e. null for a reference type, and zero or false for a primitive type. Note that the JLS (see 8.3.1.3) does not say what transient means, but defers to the Java Object Serialization Specification. Other serialization mechanisms may pay attention to a field's transient-ness. Or they may ignore it.

(Note that the JLS permits a static field to be declared as transient. This combination doesn't make sense for Java Object Serialization, since it doesn't serialize statics anyway. However, it could make sense in other contexts, so there is some justification for not forbidding it outright.)

The volatile modifier tells the JVM that writes to the field should always be synchronously flushed to memory, and that reads of the field should always read from memory. This means that fields marked as volatile can be safely accessed and updated in a multi-thread application without using native or standard library-based synchronization. Similarly, reads and writes to volatile fields are atomic. (This does not apply to >>non-volatile<< long or double fields, which may be subject to "word tearing" on some JVMs.) The relevant parts of the JLS are 8.3.1.4, 17.4 and 17.7.

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

Another good resource is http://www.javacamp.org/javavscsharp/ This site enumerates many examples that ilustrate almost all the differences between these two programming languages.

About the Attributes, Java has Annotations, that work almost the same way.

In case you came here looking for current timestamp

var date      = new Date();
var timestamp = date.getTime();

or simply

new Date().getTime();
//console.log(new Date().getTime());

You can try something like this.

<button class="button" ng-disabled="(!data.var1 && !data.var2) ? false : true">
</button>

Its working fine for me.

Got the same problem in 11 11 19, so sorry for possible necroposting. The only what helped was next solution:

var drop = $('#product_1');   // get our element, **must be unique**;
var settings = drop.attr('data-krajee-select2');  pick krajee attrs of our elem;
var drop_id = drop.attr('id');  // take id 
settings = window[settings];  // take previous settings from window;
drop.select2(settings);  // initialize select2 element with it;
$('.kv-plugin-loading').remove(); // remove loading animation;

It's, maybe, not so good, nice and precise solution, and maybe I still did not clearly understood, how it works and why, but this was the only, what keeps my select2 dropdowns, gotten by ajax, alive. Hope, this solution will be usefull or may push you in right decision in problem fixing

firstarray and secondarray are converted to a pointer to int, when passed to printarray().

printarray(int arg[], ...) is equivalent to printarray(int *arg, ...)

However, this is not specific to C++. C has the same rules for passing array names to a function.

Collection c;

Iterator iter = c.iterator();

Object first = iter.next();

(This is the closest you'll get to having the "first" element of a Set. You should realize that it has absolutely no meaning for most implementations of Set. This may have meaning for LinkedHashSet and TreeSet, but not for HashSet.)

NSTimer has been renamed to Timer in Swift 4.2. this syntax will work in 4.2:

let timer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(UIMenuController.update), userInfo: nil, repeats: true)

<style type="text/css">
body {background:none transparent;
}
</style>

that might work (if you put in the iframe) along with

<iframe src="stuff.htm" allowtransparency="true">

    return Deal::with(["redeem" => function($q){
        $q->where('user_id', '=', 1);
    }])->get();

this worked for me

Create an initializer for it:

# config/initializers/time_formats.rb

Add something like this to it:

Time::DATE_FORMATS[:custom_datetime] = "%d.%m.%Y"

And then use it the following way:

post.updated_at.to_s(:custom_datetime)

Here is a the list of ajax libraries comparison based on the features and support. I prefer to use fetch for only client side development or isomorphic-fetch for using in both client side and server side development.

For more information on isomorphic-fetch vs fetch

Sure there is. You can for example use the conditional expressions. For example:

<span th:text="${someObject.someProperty != null} ? ${someObject.someProperty} : 'null value!'">someValue</span>

You can even omit the "else" expression:

<span th:text="${someObject.someProperty != null} ? ${someObject.someProperty}">someValue</span>

You can also take a look at the Elvis operator to display default values.

There's always the chr() function, which converts an ascii code to string.

ie. something like: INSERT INTO table VALUES ( CONCAT( 'J', CHR(38), 'J' ) )

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"

You need to escape the quotation marks:

String name = "\"john\"";

The toString() implementation of java.util.Date does not depend on the way the class is imported. It always returns a nice formatted date.

The toString() you see comes from another class.

Specific import have precedence over wildcard imports.

in this case

import other.Date
import java.util.*

new Date();

refers to other.Date and not java.util.Date.

The odd thing is that

import other.*
import java.util.*

Should give you a compiler error stating that the reference to Date is ambiguous because both other.Date and java.util.Date matches.

while IFS= read -d $'\0' -r file ; do 
    echo $file; ls $file ; 
done < <(find /path/to/dir/ -mindepth 1 -maxdepth 1 -type d -print0)

Original post (Does not work with spaces)

Inspired by Boldewyn: Example of loop with find command.

for D in $(find /path/to/dir/ -mindepth 1 -maxdepth 1 -type d) ; do
    echo $D ;
done

Try:

var selectedVal;

for( i = 0; i < document.form_name.gender.length; i++ )
{
  if(document.form_name.gender[i].checked)
    selectedVal = document.form_name.gender[i].value; //male or female
    break;
  }
}

In a Brazilian Portuguese ABNT2 keyboard I have a similar issue to the one reported by JoshDM. In the file sublime-keymap I have:

{ "keys": ["ctrl+/"], "command": "toggle_comment", "args": { "block": false } },
{ "keys": ["ctrl+shift+/"], "command": "toggle_comment", "args": { "block": true } },

But I have to use ctrl+; and ctrl+shift+;. On my keyboard, ; is on the left of /.

It seems like a bug.

As I can see the array is of String only.For each loop can be used to get individual element of the array and put them in local inner class for use.

Below is the code snippet for it :

     //WorkAround 
    for (String color : colors ){

String pos = Character.toUpperCase(color.charAt(0)) + color.substring(1);
JMenuItem Jmi =new JMenuItem(pos);
Jmi.setIcon(new IconA(color));

Jmi.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            JMenuItem item = (JMenuItem) e.getSource();
            IconA icon = (IconA) item.getIcon();
            // HERE YOU USE THE String color variable and no errors!!!
            Color kolorIkony = getColour(color); 
            textArea.setForeground(kolorIkony);
        }
    });

    mnForeground.add(Jmi);
}

}

success is the callback that is invoked when the request is successful and is part of the $.ajax call. done is actually part of the jqXHR object returned by $.ajax(), and replaces success in jQuery 1.8.

I just want to add my solution:

I use german umlauts like ö, ü, ä and got the same error.
@Jarek Zmudzinski just told you how it works, but here is mine:

Add this code to the top of your Controller: # encoding: UTF-8
(for example to use flash message with umlauts)

example of my Controller:

# encoding: UTF-8
class UserController < ApplicationController

Now you can use ö, ä ,ü, ß, "", etc.

Find below code if you want to download the contents of the specified URL also want to saves it to a file.

<?php
$ch = curl_init();
/**
* Set the URL of the page or file to download.
*/
curl_setopt($ch, CURLOPT_URL,'http://news.google.com/news?hl=en&topic=t&output=rss');

$fp = fopen('rss.xml', 'w+');
/**
* Ask cURL to write the contents to a file
*/
curl_setopt($ch, CURLOPT_FILE, $fp);

curl_exec ($ch);

curl_close ($ch);
fclose($fp);
?>

If you want to downloads file from the FTP server you can use php FTP extension. Please find below code:

<?php
$SERVER_ADDRESS="";
$SERVER_USERNAME="";
$SERVER_PASSWORD="";
$conn_id = ftp_connect($SERVER_ADDRESS);

// login with username and password
$login_result = ftp_login($conn_id, $SERVER_USERNAME, $SERVER_PASSWORD);

$server_file="test.pdf" //FTP server file path 
$local_file = "new.pdf"; //Local server file path 

##----- DOWNLOAD $SERVER_FILE AND SAVE TO $LOCAL_FILE--------##
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

ftp_close($conn_id);
?>

One option is using Object.keys():

Object.keys(driversCounter)

It works fine for modern browsers (however, Internet Explorer supports it starting from version 9 only).

To add compatible support you can copy the code snippet provided in MDN.

Sven said it all, just be very cautious because of automatic type adjustments when append is called.

In [2]: import numpy as np

In [3]: a = np.array([1,2,3])

In [4]: b = np.array([1.,2.,3.])

In [5]: c = np.array(['a','b','c'])

In [6]: np.append(a,b)
Out[6]: array([ 1.,  2.,  3.,  1.,  2.,  3.])

In [7]: a.dtype
Out[7]: dtype('int64')

In [8]: np.append(a,c)
Out[8]: 
array(['1', '2', '3', 'a', 'b', 'c'], 
      dtype='|S1')

As you see based on the contents the dtype went from int64 to float32, and then to S1

They are both the same functionally but the .min one has all unnecessary characters removed in order to make the file size smaller.

Just to point out as well, you are better using the minified version (.min) for your live environment as Google are now checking on page loading times. Having all your JS file minified means they will load faster and will score you more brownie points.

You can get an addon for Mozilla called Page Speed that will look through your site and show you all the .JS files and provide minified versions (amongst other things).

If anyone needs the registry entries for Windows 7 64-bit, here they are. What was good for me as to remove the overlays for items not really used often: Drop Box, Google Drive, Microsoft Products, and just kept the overlays for Tortoise. These are all the overlays - nothing is removed.

** Caution ** Playing with the registry can make your system unstable. Be sure to backup your registry. See this Google search on various ways to backup your registry or registry setting(s).

It seems that this is the correct way window.location.assign("http://www.mozilla.org");

• https://developer.mozilla.org/en-US/docs/Web/API/Window/location
• https://www.w3schools.com/js/js_window_location.asp
• https://jstricks.com/javascript-redirect-page-redirection/

which(df==my.val, arr.ind=TRUE)

Most simple way (assumed you want to remove the element)

<span id='close' onclick='this.parentNode.parentNode.parentNode.removeChild(this.parentNode.parentNode); return false;'>x</span>

Add this inside your div, an example here.

You may also use something like this

window.onload = function(){
    document.getElementById('close').onclick = function(){
        this.parentNode.parentNode.parentNode
        .removeChild(this.parentNode.parentNode);
        return false;
    };
};

An Example Here.

Css for close button

#close {
    float:right;
    display:inline-block;
    padding:2px 5px;
    background:#ccc;
}

You may add a hover effect like

#close:hover {
    float:right;
    display:inline-block;
    padding:2px 5px;
    background:#ccc;
    color:#fff;
}

Something like this one.

If the name's dynamic, then you must have something like

$arr[$key]

which'd mean that $key contains the value of the key.

You can use array_keys() to get ALL the keys of an array, e.g.

$arr = array('a' => 'b', 'c' => 'd')
$x = array_keys($arr);

would give you

$x = array(0 => 'a', 1 => 'c');

In some devices void onConfigurationChanged() may crash. User will use this code to get current screen orientation.

public int getScreenOrientation()
{
    Display getOrient = getActivity().getWindowManager().getDefaultDisplay();
    int orientation = Configuration.ORIENTATION_UNDEFINED;
    if(getOrient.getWidth()==getOrient.getHeight()){
        orientation = Configuration.ORIENTATION_SQUARE;
    } else{ 
        if(getOrient.getWidth() < getOrient.getHeight()){
            orientation = Configuration.ORIENTATION_PORTRAIT;
        }else { 
             orientation = Configuration.ORIENTATION_LANDSCAPE;
        }
    }
    return orientation;
}

And use

if (orientation==1)        // 1 for Configuration.ORIENTATION_PORTRAIT
{                          // 2 for Configuration.ORIENTATION_LANDSCAPE
   //your code             // 0 for Configuration.ORIENTATION_SQUARE
}

Since XAMPP went through some modifications, the file is now at xampp/php/php.ini.

simply use

Above of all, I found this library right here. Works out of the box perfectly on a Bootstrap-3 environment.

Bootstrap-3 Clock-Picker

CSS

<link rel="stylesheet" type="text/css" href="dist/bootstrap-clockpicker.min.css">

HTML

<div class="input-group clockpicker">
    <input type="text" class="form-control" value="09:30">
    <span class="input-group-addon">
        <span class="glyphicon glyphicon-time"></span>
    </span>
</div>

JAVASCRIPT

<script type="text/javascript" src="dist/bootstrap-clockpicker.min.js"></script>
<script type="text/javascript">
    $('.clockpicker').clockpicker();
</script>

As simple as that! Find more examples on the link above.

If you are using Bootstrap-4, the most popular time/date picker library available right now is Tempus Dominus. It is not fancy looking, but much responsive and modern.

Tarkus's answer works well. However, I would suggest replacing VIEWSTATE with SESSION.

The current page's VIEWSTATE only works while the current page posts back to itself and is gone once the user is redirected away to another page. SESSION persists the sort order on more than just the current page's post-back. It persists it across the entire duration of the session. This means that the user can surf around to other pages, and when he comes back to the given page, the sort order he last used still remains. This is usually more convenient.

There are other methods, too, such as persisting user profiles.

I recommend this article for a very good explanation of ViewState and how it works with a web page's life cycle: https://msdn.microsoft.com/en-us/library/ms972976.aspx

To understand the difference between VIEWSTATE, SESSION and other ways of persisting variables, I recommend this article: https://msdn.microsoft.com/en-us/library/75x4ha6s.aspx

Step 1 - Go to Google reCAPTCHA

Login then get Site Key and Secret Key

Step 2 - Download PHP code here and upload src folder on your server.

Step 3 - Use below code in your form.php

        <head>
            <title>FreakyJolly.com Google reCAPTCHA EXAMPLE form</title>
            <script src='https://www.google.com/recaptcha/api.js'></script>
        </head>

        <body>
            <?php

            require('src/autoload.php');

            $siteKey = '6LegPmIUAAAAADLwDmXXXXXXXyZAJVJXXXjN';
            $secret = '6LegPmIUAAAAAO3ZTXXXXXXXXJwQ66ngJ7AlP';

            $recaptcha = new \ReCaptcha\ReCaptcha($secret);

            $gRecaptchaResponse = $_POST['g-recaptcha-response']; //google captcha post data
            $remoteIp = $_SERVER['REMOTE_ADDR']; //to get user's ip

            $recaptchaErrors = ''; // blank varible to store error

            $resp = $recaptcha->verify($gRecaptchaResponse, $remoteIp); //method to verify captcha
            if ($resp->isSuccess()) {

               /******** 

                Add code to create User here when form submission is successful

               *****/

            } else {

                /****

                // This variable will have error when reCAPTCHA is not entered correctly.

                ****/

               $recaptchaErrors = $resp->getErrorCodes(); 
            }

We use object-scan for most of our data processing. It's conceptually very simple, but allows for a lot of cool stuff. Here is how you would solve your question

// const objectScan = require('object-scan');

const findDinner = (dinner, data) => objectScan(['*'], {
  abort: true,
  rtn: 'value',
  filterFn: ({ value }) => value.dinner === dinner
})(data);

const data = { 1: { name: 'bob', dinner: 'pizza' }, 2: { name: 'john', dinner: 'sushi' }, 3: { name: 'larry', dinner: 'hummus' } };

console.log(findDinner('sushi', data));
// => { name: 'john', dinner: 'sushi' }

.as-console-wrapper {max-height: 100% !important; top: 0}

I'm a PHP developer and to be able to work on my development environment with a certificate, I was able to do the same by finding the real SSL HTTPS/HTTP Certificate and deleting it.

The steps are :

1. In the address bar, type "chrome://net-internals/#hsts".
2. Type the domain name in the text field below "Delete domain".
3. Click the "Delete" button.
4. Type the domain name in the text field below "Query domain".
5. Click the "Query" button.
6. Your response should be "Not found".

You can find more information at : http://classically.me/blogs/how-clear-hsts-settings-major-browsers

Although this solution is not the best, Chrome currently does not have any good solution for the moment. I have escalated this situation with their support team to help improve user experience.

Edit : you have to repeat the steps every time you will go on the production site.

While File.ReadAllLines() is one of the simplest ways to read a file, it is also one of the slowest.

If you're just wanting to read lines in a file without doing much, according to these benchmarks, the fastest way to read a file is the age old method of:

using (StreamReader sr = File.OpenText(fileName))
{
        string s = String.Empty;
        while ((s = sr.ReadLine()) != null)
        {
               //do minimal amount of work here
        }
}

However, if you have to do a lot with each line, then this article concludes that the best way is the following (and it's faster to pre-allocate a string[] if you know how many lines you're going to read) :

AllLines = new string[MAX]; //only allocate memory here

using (StreamReader sr = File.OpenText(fileName))
{
        int x = 0;
        while (!sr.EndOfStream)
        {
               AllLines[x] = sr.ReadLine();
               x += 1;
        }
} //Finished. Close the file

//Now parallel process each line in the file
Parallel.For(0, AllLines.Length, x =>
{
    DoYourStuff(AllLines[x]); //do your work here
});

This has been answered to death, but this is all you need.

!!navigator.userAgent.match(/msie\s[5-8]/i)

I know this is an old question, but there is a simple, one line solution which works consistently for Chrome, Firefox, etc., as well as IE8 and above (and, for the most part, works on IE7 too - see http://www.quirksmode.org/css/selectors/ for details):

table td + td { border-left:2px solid red; }

The output is something like this:

Col1 | Col2 | Col3

What is making this work is that you are defining a border only on table cells which are adjacent to another table cell. In other words, you're applying the CSS to all cells in a row except the first one.

By applying a left border to the second through the last child, it gives the appearance of the line being "between" the cells.

Great answers, but just wanted to mention a gotcha that "pass" keyword will not work in the if/else part of the list-comprehension (as posted in the examples mentioned above).

#works
list1 = [10, 20, 30, 40, 50]
newlist2 = [x if x > 30 else x**2 for x in list1 ]
print(newlist2, type(newlist2))

#but this WONT work
list1 = [10, 20, 30, 40, 50]
newlist2 = [x if x > 30 else pass for x in list1 ]
print(newlist2, type(newlist2))

This is tried and tested on python 3.4. Error is as below:

newlist2 = [x if x > 30 else pass for x in list1 ]                                    
SyntaxError: invalid syntax

So, try to avoid pass-es in list comprehensions

You need to use sqlite's prepared statements interface. Basically, the idea is that you prepare a statement with a placeholder for your blob, then use one of the bind calls to "bind" your data...

SQLite Prepared Statements

The answer that @Matthew Crumley provides is making use of the immediately invoked function expressions, to close the older 'a' function into the execution context of the returned function. I think this was the best answer, but personally, I would prefer passing the function 'a' as an argument to IIFE. I think it is more understandable.

   var a = (function(original_a) {
        if (condition) {
            return function() {
                new_code();
                original_a();
            }
        } else {
            return function() {
                original_a();
                other_new_code();
            }
        }
    })(a);

Ow, with the release of Bootstrap 3, you can use the classes of text-center for center alignment, text-left for left alignment, text-right for right alignment and text-justify for a justified alignment.

Bootstrap is a very simple frontend framework to work with, once you utilize it. As well as being very easy to customize to fit your liking.

If you don't pass the correct web URL and don't have a browser, ActivityNotFoundException occurs, so check those requirements or handle the exception explicitly. That can resolve your problem.

public static void openWebPage(Context context, String url) {
    try {
        if (!URLUtil.isValidUrl(url)) {
            Toast.makeText(context, " This is not a valid link", Toast.LENGTH_LONG).show();   
        } else {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(Uri.parse(url));
            context.startActivity(intent);
        }
    } catch (ActivityNotFoundException e) {
        Toast.makeText(context, " You don't have any browser to open web page", Toast.LENGTH_LONG).show();
    }
}

functional requirements are the main things that the user expects from the software for example if the application is a banking application that application should be able to create a new account, update the account, delete an account, etc. functional requirements are detailed and are specified in the system design

Non-functional requirement are not straight forward the requirement of the system rather it is related to usability( in some way ) for example for a banking application a major non-functional requirement will be available the application should be available 24/7 with no downtime if possible.

You can get the Parent of a control via

myControl.Parent

See MSDN: Control.Parent

You can use jQuery's attr() function, like $("#id").attr('src',"source").

I had the same problem. Here's what I figured out:

=BDP(A1&"@BGN Corp", "Issuer_parent_eqy_ticker")

A1 being the ISINs. This will return the ticker number. Then just use the ticker number to get the price.

It's just shorthand for "constructor" - and it's what the constructor is called in IL, too. For example, open up Reflector and look at a type and you'll see members called .ctor for the various constructors.

Wget currently only supports x-www-form-urlencoded data. --post-file is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example.

--post-data and --post-file work the same way: the only difference is that --post-data allows you to specify the data in the command line, while --post-file allows you to specify the path of the file that contain the data to send.

Here's the documentation:

 --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified data
           in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work in
           exactly the same way. In particular, they both expect content of the
           form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file. In
           particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.

Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN.

wget --post-data 'user=foo&password=bar' http://example.com/auth.php

Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.

Here is a single line that will create (or overwrite) the file:

File.Create("C:\my files\2010\SomeFileName.txt").Dispose()

Note: calling Dispose() ensures that the reference to the file is closed.

An alternative to GETDATE() is CURRENT_TIMESTAMP. Does the exact same thing.

create proc [dbo].[hash_pass] @family nvarchar(50), @username nvarchar(50), @pass nvarchar(Max),``` @semat nvarchar(50), @tell nvarchar(50)

as insert into tbl_karbar values (@family,@username,(select HASHBYTES('SHA1' ,@pass)),@semat,@tell)

To set the standard time zone at MariaDB you have to go to the 50-server.cnf file.

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

Then you can enter the following entry in the mysqld section.

default-time-zone='+01:00'

Example:

#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#

# this is read by the standalone daemon and embedded servers
[server]

# this is only for the mysqld standalone daemon
[mysqld]

#
# * Basic Settings
#
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking

### Default timezone ###
default-time-zone='+01:00'

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.

The change must be made via the configuration file, otherwise the MariaDB server will reset the mysql tables after a restart!

.NET does this for you. In your AssemblyInfo.cs file, set your assembly version to major.minor.* (for example: 1.0.*).

When you build your project the version is auto generated.

The build and revision numbers are generated based on the date, using the unix epoch, I believe. The build is based on the current day, and the revision is based on the number of seconds since midnight.

My favoured method for doing this looks something like:

<xsl:stylesheet>

<xsl:output method='text'/>

<xsl:variable name='newline'><xsl:text>
</xsl:text></xsl:variable>

<!-- note that the layout there is deliberate -->

...

</xsl:stylesheet>

Then, whenever you want to output a newline (perhaps in csv) you can output something like the following:

<xsl:value-of select="concat(elem1,elem2,elem3,$newline)" />

I've used this technique when outputting sql from xml input. In fact, I tend to create variables for commas, quotes and newlines.

This is when you want a AlertDialog in a Fragment

            AlertDialog.Builder adb = new AlertDialog.Builder(getActivity());
            adb.setTitle("My alert Dialogue \n");
            adb.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

                  //some code

            } });
            adb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

                 dialog.dismiss();

                } });
            adb.show();

You can't do that in Javascript from the browser... If I were you, I would use something like browserify. Write your code using commonjs modules and then compile the javascript file into one.

In your html load the javascript file that you compiled.

Don't forget that an input field must be visible first, thereafter you're able to focus it.

$("#elementid").show();
$("#elementid input[type=text]").focus();

2021 solution, no additional packages required, Python 3

Define a class

import logging

class CustomFormatter(logging.Formatter):
    """Logging Formatter to add colors and count warning / errors"""

    grey = "\x1b[38;21m"
    yellow = "\x1b[33;21m"
    red = "\x1b[31;21m"
    bold_red = "\x1b[31;1m"
    reset = "\x1b[0m"
    format = "%(asctime)s - %(name)s - %(levelname)s - %(message)s (%(filename)s:%(lineno)d)"

    FORMATS = {
        logging.DEBUG: grey + format + reset,
        logging.INFO: grey + format + reset,
        logging.WARNING: yellow + format + reset,
        logging.ERROR: red + format + reset,
        logging.CRITICAL: bold_red + format + reset
    }

    def format(self, record):
        log_fmt = self.FORMATS.get(record.levelno)
        formatter = logging.Formatter(log_fmt)
        return formatter.format(record)

Instantiate logger

# create logger with 'spam_application'
logger = logging.getLogger("My_app")
logger.setLevel(logging.DEBUG)

# create console handler with a higher log level
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)

ch.setFormatter(CustomFormatter())

logger.addHandler(ch)

And use!

logger.debug("debug message")
logger.info("info message")
logger.warning("warning message")
logger.error("error message")
logger.critical("critical message")

The full color scheme

For windows

This solution works on Mac OS, IDE terminals. Looks like the Windows command prompt doesn't have colors at all by default. Here are instructions on how to enable them, which I haven't try https://www.howtogeek.com/322432/how-to-customize-your-command-prompts-color-scheme-with-microsofts-colortool/

I am describing a simple method which worked very smoothly in Python (Django Framework).

1. While sending the request, send the request like this

http://server/action?id=a,b

2. Now in my backend, I split the value received with a split function which always creates a list.

id_filter = id.split(',')

Example: So if I send two values in the request,

http://server/action?id=a,b

then the filter on the data is

id_filter = ['a', 'b']

If I send only one value in the request,

http://server/action?id=a

then the filter outcome is

id_filter = ['a']

3. To actually filter the data, I simply use the 'in' function

queryset = queryset.filter(model_id__in=id_filter)

which roughly speaking performs the SQL equivalent of

WHERE model_id IN ('a', 'b')

with the first request and,

WHERE model_id IN ('a')

with the second request.

This would work with more than 2 parameter values in the request as well !

For proper error handling:

#!/bin/bash

set -Ee    
trap "echo error" EXIT    
test -e ${FILENAME} || exit
while read -r line
do
    echo ${line}
done < ${FILENAME}

You can use text attributes to hide a bar button:

barButton.enabled = false
barButton.setTitleTextAttributes([NSForegroundColorAttributeName : UIColor.clearColor()], forState: .Normal)

Also see my solution with UIBarButtonItem extension for the similar question: Make a UIBarButtonItem disapear using swift IOS

You have 2 options:

• You can take the Down from the bad migration and put it in a new migration (you will also need to make the subsequent changes to the model). This is effectively rolling up to a better version.

  I use this option on things that have gone to multiple environments.

• The other option is to actually run Update-Database –TargetMigration: TheLastGoodMigration against your deployed database and then delete the migration from your solution. This is kinda the hulk smash alternative and requires this to be performed against any database deployed with the bad version.

  Note: to rescaffold the migration you can use Add-Migration [existingname] -Force. This will however overwrite your existing migration, so be sure to do this only if you have removed the existing migration from the database. This does the same thing as deleting the existing migration file and running add-migration

  I use this option while developing.

Try this:

 git fetch --all
 git reset --hard origin/master

Explanation:

git fetch downloads the latest from remote without trying to merge or rebase anything.

Please let me know if you have any questions!

this is an .htaccess file that forward almost all to index.php

# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_URI} !-l
RewriteCond %{REQUEST_FILENAME} !\.(ico|css|png|jpg|gif|js)$ [NC]
# otherwise forward it to index.php
RewriteRule . index.php

then is up to you parse $_SERVER["REQUEST_URI"] and route to picture.php or whatever

Use -regex:

From the man page:

-regex pattern
       File name matches regular expression pattern.  This is a match on the whole path, not a search.  For example, to match a file named './fubar3',  you  can  use  the
       regular expression '.*bar.' or '.*b.*3', but not 'b.*r3'.

Also, I don't believe find supports regex extensions such as \d. You need to use [0-9].

find . -regex '.*test\.log\.[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]\.zip'

Fortunately there has been some efforts for the generic programming in python . There is a library : generic

Here is the documentation for it: http://generic.readthedocs.org/en/latest/

It hasn't progress over years , but you can have a rough idea how to use & make your own library.

Cheers

I use:

delete $array[$index];

Perldoc delete.

In my case, I had:

const handleOnChange = (e: ChangeEvent) => {
  doSomething(e.target.value);
}

And the issue was that I did not provide a type argument to ChangeEvent so that it knows e.target was an HTMLInputElement. Even if I manually told it that target was an input element (e.g. const target: HTMLInputElement = e.target), the ChangeEvent still didn't know that made sense.

The solution was to do:

// add type argument
const handleOnChange = (e: ChangeEvent<HTMLInputElement>) => {

I've been using ant32's answer above for several years. However I've found that is thorws an error in python 3 because mogrify returns a byte string.

Converting explicitly to bytse strings is a simple solution for making code python 3 compatible.

args_str = b','.join(cur.mogrify("(%s,%s,%s,%s,%s,%s,%s,%s,%s)", x) for x in tup) 
cur.execute(b"INSERT INTO table VALUES " + args_str)

You can subclass UINavigationController, set itself as the delegate, and set the backBarButtonItem in the delegate method navigationController:willShowViewController:animated:

@interface Custom_NavigationController : UINavigationController <UINavigationControllerDelegate>

@end

@implementation Custom_NavigationController

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.delegate = self;
}

#pragma mark - UINavigationControllerDelegate

- (void)navigationController:(UINavigationController *)navigationController     willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    viewController.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];
}

@end

Even nicer is this version I created from a plugin I found:

function filesize_formatted($path)
{
    $size = filesize($path);
    $units = array( 'B', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB');
    $power = $size > 0 ? floor(log($size, 1024)) : 0;
    return number_format($size / pow(1024, $power), 2, '.', ',') . ' ' . $units[$power];
}

Note from filesize() doc

Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB

It varies based on the options that you pass to install and the contents of the distutils configuration files on the system/in the package. I don't believe that any files are modified outside of directories specified in these ways.

Notably, distutils does not have an uninstall command at this time.

It's also noteworthy that deleting a package/egg can cause dependency issues – utilities like easy_install attempt to alleviate such problems.

Just create this batch file and run it on windows. It basically would kill all chrome instances and then would start chrome with disabling security. Save the following script in batch file say ***.bat and double click on it.

TASKKILL /F /IM chrome.exe
start chrome.exe --args --disable-web-security –-allow-file-access-from-files

First you need to make sure if both of your files are in the same working directory. Next, you can import the whole file. For example,

import myClass

or you can import the entire class and entire functions from the file. For example,

from myClass import

Finally, you need to create an instance of the class from the original file and call the instance objects.

Just go to the official Node.js site (nodejs.org), download and execute the installer program.

It will take care of everything and with a few clicks of 'Next' you'll get the latest Node.js version running on your machine. Since 2020 it's the recommended way to update NodeJS. It's the easiest and least frustrating solution.

Pro tips

• NodeJS installation includes NPM (Node package manager).

• To check your NPM version use npm version or node --version.

• If you prefer CLI, to update NPM use npm install -g npm and then npm install -g node.

• For more details, see the docs for install command.

• Keep an eye on NodeJS blog - Vulnerabilities so you don't miss important security releases. Keep your NodeJS up-to-date.

• Operating systems supported by Node.js: Windows, Linux, MacOS, SunOS, IBM AIX.

• For Docker users, here's the official Node.js image.

• Troubleshooting for Windows:

  If anyone gets file error 2502/2503 like myself during install, run the .msi via Administrator command prompt with command msiexec /package [node msi]

Sharing a few functions which I created for dates:

Please note that I wanted to get time for a particular location (not just UTC time). If you want UTC time, just remove loc variable and .In(loc) function call.

func GetTimeStamp() string {
     loc, _ := time.LoadLocation("America/Los_Angeles")
     t := time.Now().In(loc)
     return t.Format("20060102150405")
}
func GetTodaysDate() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("2006-01-02")
}

func GetTodaysDateTime() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("2006-01-02 15:04:05")
}

func GetTodaysDateTimeFormatted() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("Jan 2, 2006 at 3:04 PM")
}

func GetTimeStampFromDate(dtformat string) string {
    form := "Jan 2, 2006 at 3:04 PM"
    t2, _ := time.Parse(form, dtformat)
    return t2.Format("20060102150405")
}

here is the full program to make a POST rest call using spring's RestTemplate.

import java.util.HashMap;
import java.util.Map;

import org.springframework.http.HttpEntity;
import org.springframework.http.ResponseEntity;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;

import com.ituple.common.dto.ServiceResponse;

   public class PostRequestMain {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
        Map map = new HashMap<String, String>();
        map.put("Content-Type", "application/json");

        headers.setAll(map);

        Map req_payload = new HashMap();
        req_payload.put("name", "piyush");

        HttpEntity<?> request = new HttpEntity<>(req_payload, headers);
        String url = "http://localhost:8080/xxx/xxx/";

        ResponseEntity<?> response = new RestTemplate().postForEntity(url, request, String.class);
        ServiceResponse entityResponse = (ServiceResponse) response.getBody();
        System.out.println(entityResponse.getData());
    }

}

This works like champ on mac os or windows.

Remove workbench.xmi located at workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi. Then start your Eclipse or ADT. This will not erase your workspace or repository.

Remove workbench.xmi cmd:

rm workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi.

I'd go for purchase-rest-service. Reasons:

1. What is "pur chase rests ervice"? Long, concatenated words are hard to understand. I know, I'm German. "Donaudampfschifffahrtskapitänspatentausfüllungsassistentenausschreibungsstellenbewerbung."

2. "_" is harder to type than "-"

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

I used this statement.

$base = "http://$_SERVER[SERVER_NAME]:$_SERVER[SERVER_PORT]$my_web_base_path";
$url = $base . "/" . dirname(dirname(__FILE__));

I hope this will help you.

also try

## Notice the lack of quotes
iris %>% select (-c(Sepal.Length, Sepal.Width))

First, give all your links a unique id and make a css class called active:

<ul>
    <li><a id="link1" href="#/...">link 1</a></li>
    <li><a id="link2" href="#/...">link 2</a></li>
</ul>

CSS:

.active {
    font-weight: bold;
}

Jquery version:

function setActiveLink(setActive){
    if ($("a").hasClass('active'))
        $("a").removeClass('active');
    if (setActive)
        $("#"+setActive).addClass('active');
}

$(function() {
    $("a").click(function() {
        setActiveLink(this.id);
    });
});

Vanilla javascript version:

In order to prevent selecting too many links with document.querySelectorAll, give the parent element an id called menuLinks. Add an onClick handler on the links.

<ul id="menuLinks">
    <li><a id="link1" href="#/..." onClick="setActiveLink(this.id);">link 1</a></li>
    <li><a id="link2" href="#/..." onClick="setActiveLink(this.id);">link 2</a></li>
</ul>

Code:

function setActiveLink(setActive){
    var links = document.querySelectorAll("#menuLinks a");
    Array.prototype.map.call(links, function(e) {
        e.className = "";
        if (e.id == setActive)
            e.className = "active";
    })
}

Depending on the situation and or your style, you might also wanna use print inside your <% %> tags, as it allows for direct output. Like:

<% if (typeof(id) != "undefined") {
     print(id);
}
else {
    print('new Model');
} %>

And for the original snippet with some concatenation:

<% if (typeof(date) != "undefined") {
    print('<span class="date">' + date + '</span>');
} %>

If you can use apache.commons.lang in your project, the easiest way would be just to use the method provided there:

public static boolean containsWhitespace(CharSequence seq)

Check whether the given CharSequence contains any whitespace characters.

Parameters:

seq - the CharSequence to check (may be null) 

Returns:

true if the CharSequence is not empty and contains at least 1 whitespace character

It handles empty and null parameters and provides the functionality at a central place.

I changed the output path of the service. it should be inside bin folder of the service project. Once I put the output path back to bin, it worked.

CAST(Round(MySum * 20.0 /100, 0) AS INT)

FYI

MySum * 20 /100, I get 11

This is because when all 3 operands are INTs, SQL Server will do perform integer maths, from left to right, truncating all intermediate results.

58 * 20 / 100 => 1160 / 100 => 11 (truncated from 11.6)

Also for the record ROUND(m,n) returns the result to n decimal places, not n significant figures.

At least in Postgres you can use the following statement:

SELECT EntityID, EntityName, EntityProfile IS NOT NULL AS HasProfile FROM Entity

In Java there is nothing at language level similar to ref. In Java there is only passing by value semantic

For the sake of curiosity you can implement a ref-like semantic in Java simply wrapping your objects in a mutable class:

public class Ref<T> {

    private T value;

    public Ref(T value) {
        this.value = value;
    }

    public T get() {
        return value;
    }

    public void set(T anotherValue) {
        value = anotherValue;
    }

    @Override
    public String toString() {
        return value.toString();
    }

    @Override
    public boolean equals(Object obj) {
        return value.equals(obj);
    }

    @Override
    public int hashCode() {
        return value.hashCode();
    }
}

testcase:

public void changeRef(Ref<String> ref) {
    ref.set("bbb");
}

// ...
Ref<String> ref = new Ref<String>("aaa");
changeRef(ref);
System.out.println(ref); // prints "bbb"

Here is a working modified version from some of the above-indicated solutions.

Add another class ListView:

package com.example.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.AbsListView;

public class ListView extends android.widget.ListView {

    private OnScrollListener onScrollListener;
    private OnDetectScrollListener onDetectScrollListener;

    public ListView(Context context) {
        super(context);
        onCreate(context, null, null);
    }

    public ListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        onCreate(context, attrs, null);
    }

    public ListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        onCreate(context, attrs, defStyle);
    }

    @SuppressWarnings("UnusedParameters")
    private void onCreate(Context context, AttributeSet attrs, Integer defStyle) {
        setListeners();
    }

    private void setListeners() {
        super.setOnScrollListener(new OnScrollListener() {

            private int oldTop;
            private int oldFirstVisibleItem;

            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
                if (onScrollListener != null) {
                    onScrollListener.onScrollStateChanged(view, scrollState);
                }
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                if (onScrollListener != null) {
                    onScrollListener.onScroll(view, firstVisibleItem, visibleItemCount, totalItemCount);
                }

                if (onDetectScrollListener != null) {
                    onDetectedListScroll(view, firstVisibleItem);
                }
            }

            private void onDetectedListScroll(AbsListView absListView, int firstVisibleItem) {
                View view = absListView.getChildAt(0);
                int top = (view == null) ? 0 : view.getTop();

                if (firstVisibleItem == oldFirstVisibleItem) {
                    if (top > oldTop) {
                        onDetectScrollListener.onUpScrolling();
                    } else if (top < oldTop) {
                        onDetectScrollListener.onDownScrolling();
                    }
                } else {
                    if (firstVisibleItem < oldFirstVisibleItem) {
                        onDetectScrollListener.onUpScrolling();
                    } else {
                        onDetectScrollListener.onDownScrolling();
                    }
                }

                oldTop = top;
                oldFirstVisibleItem = firstVisibleItem;
            }
        });
    }

    @Override
    public void setOnScrollListener(OnScrollListener onScrollListener) {
        this.onScrollListener = onScrollListener;
    }

    public void setOnDetectScrollListener(OnDetectScrollListener onDetectScrollListener) {
        this.onDetectScrollListener = onDetectScrollListener;
    }
}

And an interface:

public interface OnDetectScrollListener {

    void onUpScrolling();

    void onDownScrolling();
}

And finally how to use:

com.example.view.ListView listView = (com.example.view.ListView) findViewById(R.id.list);
listView.setOnDetectScrollListener(new OnDetectScrollListener() {
    @Override
    public void onUpScrolling() {
        /* do something */
    }

    @Override
    public void onDownScrolling() {
        /* do something */
    }
});

In your XML layout:

<com.example.view.ListView
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

This is my first topic, do not judge me harshly. =)

As of rails 5 you can also use rails instead of rake

Rails 3 - 4

# < rails-5.0
rake db:migrate:up VERSION=20160920130051

Rails 5

# >= rails-5.0
rake db:migrate:up VERSION=20160920130051

# or

rails db:migrate:up VERSION=20160920130051

As a comment, I had to allow a customer to execute a class in a jar which meant that the manifest file couldn't be modified (they couldn't be expected to do that). Thanks to the post by Anthony and samy-delux's comment, this is what the customer can now run to access the main of the specific class:

java -cp c:\path\to\jar\jarFile.jar com.utils.classpath -e -v textString

Since it is absolutely positioned you can use top: 50% to vertically align it in the center.

But then you run into the issue of the page being bigger than you want it to be. For that you can use the overflow: hidden for the parent div. This is what I used to create the same effect:

The CSS:

div.parent {
    width: 100%;
    height: 300px;
    position: relative;
    overflow: hidden;
}
div.parent div.absolute {
    position: absolute;
    top: 50%;
    height: 300px;
}

The HTML:

<div class="parent">
    <div class="absolute">This is vertically center aligned</div>
</div>

I just type following keywords in the opened terminal;

1. powershell
2. bash
3. cmd
4. node
5. python (or python3)

See details in the below image. (VSCode version 1.19.1 - windows 10 OS)

It works on VS Code Mac as well. I tried it with VSCode (Version 1.20.1)

The easiest way is through keyword arguments:

class City():
  def __init__(self, city=None):
    pass

someCity = City(city="Berlin")

This is pretty basic stuff. Maybe look at the Python documentation?

This works for me:

window.addEventListener("beforeunload", function(event) {_x000D_
  event.returnValue = "You may have unsaved Data";_x000D_
});

Walkthough on what is MUL, PRI and UNI in MySQL?

From the MySQL 5.7 documentation:

• If Key is PRI, the column is a PRIMARY KEY or is one of the columns in a multiple-column PRIMARY KEY.
• If Key is UNI, the column is the first column of a UNIQUE index. (A UNIQUE index permits multiple NULL values, but you can tell whether the column permits NULL by checking the Null field.)
• If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

Live Examples

Control group, this example has neither PRI, MUL, nor UNI:

mysql> create table penguins (foo INT);
Query OK, 0 rows affected (0.01 sec)

mysql> desc penguins;
+-------+---------+------+-----+---------+-------+

+-------+---------+------+-----+---------+-------+
1 row in set (0.00 sec)

A table with one column and an index on the one column has a MUL:

+-------+---------+------+-----+---------+-------+
2 rows in set (0.00 sec)

A table with two separate indexes on two columns has MUL for each one

mysql> create table penguins (foo INT, bar int, index(foo), index(bar));
Query OK, 0 rows affected (0.01 sec)

mysql> desc penguins;

+-------+---------+------+-----+---------+-------+
2 rows in set (0.00 sec)

A table with an Index spanning three columns has MUL on the first:

mysql> create table penguins (foo INT,

Stick that in your neocortex and set the dial to "frappe".

Using .one ensures this is done only once and not repeatedly.

$(window).one("focus", function() {
    localStorage.clear();
});

It is okay to put several document.ready event listeners (if you need other events to execute multiple times) as long as you do not overdo it, for the sake of readability.

.one is especially useful when you want local storage to be cleared only once the first time a web page is opened or when a mobile application is installed the first time.

   // Fired once when document is ready
   $(document).one('ready', function () {
       localStorage.clear();
   });

Use hashlib.md5 in Python 3.

import hashlib

source = '000005fab4534d05api_key9a0554259914a86fb9e7eb014e4e5d52permswrite'.encode()
md5 = hashlib.md5(source).hexdigest() # returns a str
print(md5) # a02506b31c1cd46c2e0b6380fb94eb3d

If you need byte type output, use digest() instead of hexdigest().

For Python 3 :

pip3 install virtualenv

python3 -m venv venv_name

source venv_name/bin/activate  #key step

pip3 install "package-name"

The difference between a variable, field, attribute, and property in Java:

A variable is the name given to a memory location. It is the basic unit of storage in a program.

A field is a data member of a class. Unless specified otherwise, a field can be public, static, not static and final.

An attribute is another term for a field. It’s typically a public field that can be accessed directly.

• In NetBeans or Eclipse, when we type object of a class and after that dot(.) they give some suggestion which are called Attributes.

A property is a term used for fields, but it typically has getter and setter combination.

You need to use cell.Text = "#N/A" instead of cell.Value = "#N/A". The error in the cell is actually just text stored in the cell.

You are right that this has long since been implemented in .NET Core.

At the time of writing (September 2019), the project.json file of NuGet 3.x+ has been superseded by PackageReference (as explained at https://docs.microsoft.com/en-us/nuget/archive/project-json).

To get access to the *Async methods of the HttpClient class, your .csproj file must be correctly configured.

Open your .csproj file in a plain text editor, and make sure the first line is
<Project Sdk="Microsoft.NET.Sdk.Web">
(as pointed out at https://docs.microsoft.com/en-us/dotnet/core/tools/project-json-to-csproj#the-csproj-format).

To get access to the *Async methods of the HttpClient class, you also need to have the correct package reference in your .csproj file, like so:

<ItemGroup>
    <!-- ... -->
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <!-- ... -->
</ItemGroup>

(See https://docs.microsoft.com/en-us/nuget/consume-packages/package-references-in-project-files#adding-a-packagereference. Also: We recommend applications targeting ASP.NET Core 2.1 and later use the Microsoft.AspNetCore.App metapackage, https://docs.microsoft.com/en-us/aspnet/core/fundamentals/metapackage)

Methods such as PostAsJsonAsync, ReadAsAsync, PutAsJsonAsync and DeleteAsync should now work out of the box. (No using directive needed.)

Update: The PackageReference tag is no longer needed in .NET Core 3.0.

You can either use the == operator or the Object.equals(Object) method.

The == operator checks whether the two subjects are the same object, whereas the equals method checks for equal contents (length and characters).

if(objectA == objectB) {
   // objects are the same instance. i.e. compare two memory addresses against each other.
}

if(objectA.equals(objectB)) {
   // objects have the same contents. i.e. compare all characters to each other 
}

Which you choose depends on your logic - use == if you can and equals if you do not care about performance, it is quite fast anyhow.

String.intern() If you have two strings, you can internate them, i.e. make the JVM create a String pool and returning to you the instance equal to the pool instance (by calling String.intern()). This means that if you have two Strings, you can call String.intern() on both and then use the == operator. String.intern() is however expensive, and should only be used as an optimalization - it only pays off for multiple comparisons.

All in-code Strings are however already internated, so if you are not creating new Strings, you are free to use the == operator. In general, you are pretty safe (and fast) with

if(objectA == objectB || objectA.equals(objectB)) {

}

if you have a mix of the two scenarios. The inline

if(objectA == null ? objectB == null : objectA.equals(objectB)) {

}

can also be quite useful, it also handles null values since String.equals(..) checks for null.

I'm note sure about this one, but i think these need to be "global" to the website.

Top-level / companion object for static properties

Top-level

When the properties are somewhat related to a class, define them as top-level properties just before the class declaration:

const val MAX_ATTEMPTS = 3
private const val DEFAULT_NAME = "Guest"
private const val MIN_AGE = 16

data class User(val id: String, val name: String = DEFAULT_NAME)

This is similar to the static properties in Java.

When the properties are completely independent of any class, you can define them as top-level in a separate file without the class.

companion object

When the properties are closely related to a class and will be used only in that class, define them inside a companion object:

data class User(val id: String, val name: String = DEFAULT_NAME) {
    companion object {
        const val DEFAULT_NAME = "Guest"
        const val MIN_AGE = 16
    }
}

Top-level / companion object for static methods

Top-level

Similar to the properties above, when the functions are somewhat related to a class, define them just above the class:

fun getAllUsers() { }

fun getProfileFor(userId: String) { }

data class User(val id: String, val name: String)

Usage:

val userList = getAllUsers()

companion object

When the functions are closely related to a class, define them inside a companion object:

data class User(val id: String, val name: String) {

    companion object {

        fun getAll() { }

        fun profileFor(userId: String) { }
    }
}

Usage:

val userProfile = User.profileFor("34")

This is similar to the static methods in Java.

The top-level functions are often more idiomatic to Kotlin. A better reason to define functions inside the companion object is when you are extending a companion object with an interface. An example of this is shown in the singleton section.

Nested class for static class

When the classes with related functionalities belong together, they can be grouped together by nesting:

class User(val id: String, val name: String) {
    class UserAccess : UserDao {
        override fun add(user: User) { }
        override fun remove(id: String) { }
    }
}

This is equivalent to the static nested classes in Java. The UserAccess class here implements an interface UserDao.

Usage:

fun main() {
    val john = User("34", "John")
    val userAccess = User.UserAccess()
    userAccess.add(john)
}

Singleton object for static INSTANCE

Top-level

When you just want a single object of a class, you no longer need to create a static INSTANCE inside a class like in Java. Simply use a top-level object declaration:

object UserAccess : UserDao {
    override fun add(user: User) { }
    override fun remove(id: String) { }
}

Notice also how easy it is to extend an interface or a class in a singleton.

The code above, under the hood, produces the following static INSTANCE singleton pattern in Java (simplified):

public final class UserAccess implements UserDao {
   public static final UserAccess INSTANCE;

   public void add(User user) { }

   public void remove(String id) { }

   private UserAccess() { }

   static { INSTANCE = new UserAccess();}
}

companion object

When the singleton is closely related to a class use companion object:

data class User(val id: String, val name: String) {
    companion object : UserDao {
        override fun add(user: User) { }
        override fun remove(id: String) { }
    }
}

This way you get more elegant naming: User.add(john). Also, you make the intent clear that this singleton is only used as a utility for the User class. You can also use the object without the companion keyword inside the class, if you want multiple singletons or groups of functions/properties.

companion object for static factory

Factory functions in Koltin are created using the companion object. Factory functions are useful when you want to provide multiple ways to create an object where the object construction process is complex or when multiple constructors are not expressive enough.

For example, the newInstance() factory function in the following snippet creates a user by generating the id automatically:

class User private constructor(val id: Long, val name: String) {
    companion object {
        private var currentId = 0L;
        fun newInstance(name: String) = User(currentId++, name)
    }
}

This is equivalent to the static factory methods in Java.

The constructor is kept private but the companion object has access to the constructor.

In the code above, consistency of the next id generation is guaranteed because a companion object is a singleton, only one object will keep track of the id, there won't be any duplicate ids.

Also notice that companion objects can have properties (currentId in this case) to represent state.

Usage:

val john = User.newInstance("John")

@JvmStatic for Java interoperability

The static concept of Java doesn't exist in Kotlin. A companion object is an instance of a real class called Companion. So, when you call the Kotlin code from Java, an object of the Companion class is first instantiated behind the scenes. You need to call the function using the Companion object in Java:

Profile userProfile = User.Companion.profileFor("34");

For the idiomatic Java naming and less verbosity, use @JvmStatic annotation on that function or property:

companion object {
    @JvmStatic
    fun profileFor(userId: String): Profile { }
}

The @JvmStatic annotation creates a separate pure static copy of the getProfileFor() function. Now you can use it from Java with regular syntax:

Profile userProfile = User.profileFor("34");

That's it! Hope the examples are useful for your projects.

these days div is the new norm

<div style="float:left"><img.. ></div>
<div style="float:right">text</div>
<div style="clear:both"/>

better way is "destroy and remove" instead of "close" it will remove dialog's "html" from the DOM

$(this).closest('.ui-dialog-content').dialog('destroy').remove();

In case you have a form you can add a class name as such:

<form id="my-form">
  <input class="js-input" type="text" name="samplename" />
  <input class="js-input" type="text" name="samplename" />
  <input class="submit" type="submit" value="Submit" />
</form>

you can then use the addClassRules method of validator to add your rules like this and this will apply to all the dynamically added inputs:

$(document).ready(function() {
  $.validator.addClassRules('js-input', {
    required: true,
  });
  //validate the form
  $('#my-form').validate();
});

You can use rename utility to rename multiple files by a pattern. For example following command will prepend string MyVacation2011_ to all the files with jpg extension.

rename 's/^/MyVacation2011_/g' *.jpg

or

rename <pattern> <replacement> <file-list>

Look in the file Microsoft.Common.targets

The answer to the question is in the file Microsoft.Common.targets for your target framework version.

For .Net Framework version 4.0 (and 4.5 !) the AssemblySearchPaths-element is defined like this:

    <!--
    The SearchPaths property is set to find assemblies in the following order:

        (1) Files from current project - indicated by {CandidateAssemblyFiles}
        (2) $(ReferencePath) - the reference path property, which comes from the .USER file.
        (3) The hintpath from the referenced item itself, indicated by {HintPathFromItem}.
        (4) The directory of MSBuild's "target" runtime from GetFrameworkPath.
            The "target" runtime folder is the folder of the runtime that MSBuild is a part of.
        (5) Registered assembly folders, indicated by {Registry:*,*,*}
        (6) Legacy registered assembly folders, indicated by {AssemblyFolders}
        (7) Resolve to the GAC.
        (8) Treat the reference's Include as if it were a real file name.
        (9) Look in the application's output folder (like bin\debug)
    -->
<AssemblySearchPaths Condition=" '$(AssemblySearchPaths)' == ''">
  {CandidateAssemblyFiles};
  $(ReferencePath);
  {HintPathFromItem};
  {TargetFrameworkDirectory};
  {Registry:$(FrameworkRegistryBase),$(TargetFrameworkVersion),$(AssemblyFoldersSuffix)$(AssemblyFoldersExConditions)};
  {AssemblyFolders};
  {GAC};
  {RawFileName};
  $(OutDir)
</AssemblySearchPaths>

For .Net Framework 3.5 the definition is the same, but the comment is wrong. The 2.0 definition is slightly different, it uses $(OutputPath) instead of $(OutDir).

On my machine I have the following versions of the file Microsoft.Common.targets:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets

This is with Visual Studio 2008, 2010 and 2013 installed on Windows 7.

The fact that the output directory is searched can be a bit frustrating (as the original poster points out) because it may hide an incorrect HintPath. The solution builds OK on your local machine, but breaks when you build on in a clean folder structure (e.g. on the build machine).

The direct methods and .delegate are superior APIs to .on and there is no intention of deprecating them.

The direct methods are preferable because your code will be less stringly typed. You will get immediate error when you mistype an event name rather than a silent bug. In my opinion, it's also easier to write and read click than on("click"

The .delegate is superior to .on because of the argument's order:

$(elem).delegate( ".selector", {
    click: function() {
    },
    mousemove: function() {
    },
    mouseup: function() {
    },
    mousedown: function() {
    }
});

You know right away it's delegated because, well, it says delegate. You also instantly see the selector.

With .on it's not immediately clear if it's even delegated and you have to look at the end for the selector:

$(elem).on({
    click: function() {
    },
    mousemove: function() {
    },
    mouseup: function() {
    },
    mousedown: function() {
    }
}, "selector" );

Now, the naming of .bind is really terrible and is at face value worse than .on. But .delegate cannot do non-delegated events and there are events that don't have a direct method, so in a rare case like this it could be used but only because you want to make a clean separation between delegated and non-delegated events.

This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.

[ChildActionOnly]
public ActionResult Results() 
{
    EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
    bool anyRows = custs.Any();

    if(anyRows == false)
    {
        return View("NoResults");
    }
    else
    {
        return View("OtherView");
    }
}

Modify NoResults.cshtml to a Partial.

And call this as a Partial view in the parent view

@Html.Partial("Results")

You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3

The ChildActionOnly attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC

Always show errors on a testing server. Never show errors on a production server.

Write a script to determine whether the page is on a local, testing, or live server, and set $state to "local", "testing", or "live". Then:

if( $state == "local" || $state == "testing" )
{
    ini_set( "display_errors", "1" );
    error_reporting( E_ALL & ~E_NOTICE );
}
else
{
    error_reporting( 0 );
}

I had the same problem, I was trying to listen the change on some select and actually the problem was I was using the event instead of the event.target which is the select object.

INCORRECT :

$(document).on('change', $("select"), function(el) {
    console.log($(el).val());
});

CORRECT :

$(document).on('change', $("select"), function(el) {
    console.log($(el.target).val());
});

Try the vertical-align CSS property.

#box1 {
    width: 50px;
    height: 50px;
    background: #999;
    display: inline-block;
    vertical-align: top; /* here */
}

Apply it to #box3 too.

I think you should try with :

While Semaphore initialization :

Semaphore semaphore = new Semaphore(1, true);

And in your Runnable Implementation

try 
{
   semaphore.acquire(1);
   // do stuff

} 
catch (Exception e) 
{
// Logging
}
finally
{
   semaphore.release(1);
}

restart the adb server works for me, in emulator, vmwware and virtual

adb kill-server
adb start-server

if you´re using a virtual machine, make sure you have an IP assigned with:

Alt + 1
type: netcfg

to go back:

Alt + 7

if you have:

 eth0: DOWN 0.0.0.0/XX

change your configuration to:

NAT or BRIDGE

Restart the virtual machine and server, and tried again.

if you´re using a phone or tablet:

• unplug your device

• wait a moment and plug it again

• and restart the adb server

Hope this help you

Worth mentioning that the handlebar library https://github.com/jknack/handlebars.java can trivialize many transformation tasks include toCSV.

Flask will process one request per thread at the same time. If you have 2 processes with 4 threads each, that's 8 concurrent requests.

Flask doesn't spawn or manage threads or processes. That's the responsability of the WSGI gateway (eg. gunicorn).

Here is working example in BDD style which is pretty simple and clear

given(carRepository.findByName(any(String.class))).willReturn(Optional.empty()).willReturn(Optional.of(MockData.createCarEntity()));

To test and see if you can access your MQTT server from outside world (outside of your VM or local machine), you can install one of the MQTT publishing and monitoring tools such as MQTT-Spy on your outside-world machine and then subscribe for '#" (meaning all the topics).

You can follow this by the method @hardillb mentioned in his answer above and test back and forth such as this:

On the machine with Mosquitto Server running,

On the outside-word machine with mqtt-spy running,

I have mainly mentioned mqtt-spy since it's multi-platform and easy to use. You can go with any other tool really. And also to my knowledge to run the mosquitto_sub and mosquitto_pub you need to have mosquitto-clients installed on your Linux machine running the test (in my case Ubuntu) which can be done easily by,

sudo apt-get install mosquitto-clients

I still doubt about this, but I've tried it at my script and I'm using xdebug to know how it will affect my app memory usage. The script is set on my function like this :

function gen_table_data($serv, $coorp, $type, $showSql = FALSE, $table = 'ireg_idnts') {
    $sql = "SELECT COUNT(`operator`) `operator` FROM $table WHERE $serv = '$coorp'";
    if($showSql === FALSE) {
        $sql = mysql_query($sql) or die(mysql_error());
        $data = mysql_fetch_array($sql);
        return $data[0];
    } else echo $sql;
}

And I add unset just before the return code and it give me : 160200 then I try to change it with $sql = NULL and it give me : 160224 :)

But there is something unique on this comparative when I am not using unset() or NULL, xdebug give me 160144 as memory usage

So, I think giving line to use unset() or NULL will add process to your application and it will be better to stay origin with your code and decrease the variable that you are using as effective as you can .

Correct me if I'm wrong, thanks

In the 'old days' you'd use a table and your menu items would be evenly spaced without having to explicitly state the width for the number of items.

If it wasn't for IE 6 and 7 (if that is of concern) then you can do the same in CSS.

<div class="demo">
    <span>Span 1</span>
    <span>Span 2</span>
    <span>Span 3</span>
</div>

CSS:

div.demo {
    display: table;
    width: 100%;
    table-layout: fixed;    /* For cells of equal size */
}
div.demo span {
    display: table-cell;
    text-align: center;
}

Without having to adjust for the number of items.

Example without table-layout:fixed - the cells are evenly distributed across the full width, but they are not necessarily of equal size since their width is determined by their contents.

• http://jsfiddle.net/w3dx/ULQwf/

Example with table-layout:fixed - the cells are of equal size, regardless of their contents. (Thanks to @DavidHerse in comments for this addition.)

• http://jsfiddle.net/kqHWM/

If you want the first and last menu elements to be left and right justified, then you can add the following CSS:

div.demo span:first-child {
    text-align: left;
}
div.demo span:last-child {
    text-align: right;
}

I had this problem today and just looking the building configurations in Visual Studio wasn't helping because it showed Any CPU for both the project that wasn't building and the referenced project.

I then looked in the csproj of the referenced project and found this:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
<DebugType>pdbonly</DebugType>
<Optimize>true</Optimize>
<OutputPath>bin\Release\</OutputPath>
<DefineConstants>TRACE</DefineConstants>
<ErrorReport>prompt</ErrorReport>
<WarningLevel>4</WarningLevel>
<PlatformTarget>x64</PlatformTarget>

Somehow this PlatformTarget got added in the middle of a config change and the IDE didn't seem to see it.

Removing this line from the referenced project solved my problem.

It is because you haven't qualified Cells(1, 1) with a worksheet object, and the same holds true for Cells(10, 2). For the code to work, it should look something like this:

Dim ws As Worksheet

Set ws = Sheets("SheetName")
Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents

Alternately:

With Sheets("SheetName")
    Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

EDIT: The Range object will inherit the worksheet from the Cells objects when the code is run from a standard module or userform. If you are running the code from a worksheet code module, you will need to qualify Range also, like so:

ws.Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents

or

With Sheets("SheetName")
    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

Here's technique I figured out after a bit of trial and error that allows you to preserve your XML styles and avoid the issues of using a <merge/> (i.e. inflate() requires a merge to attach to root, and returns the root node). No runtime new TableRow()s or new TextView()s required.

Code

Note: Here CheckBalanceActivity is some sample Activity class

TableLayout table = (TableLayout)CheckBalanceActivity.this.findViewById(R.id.attrib_table);
for(ResourceBalance b : xmlDoc.balance_info)
{
    // Inflate your row "template" and fill out the fields.
    TableRow row = (TableRow)LayoutInflater.from(CheckBalanceActivity.this).inflate(R.layout.attrib_row, null);
    ((TextView)row.findViewById(R.id.attrib_name)).setText(b.NAME);
    ((TextView)row.findViewById(R.id.attrib_value)).setText(b.VALUE);
    table.addView(row);
}
table.requestLayout();     // Not sure if this is needed.

attrib_row.xml

<?xml version="1.0" encoding="utf-8"?>
<TableRow style="@style/PlanAttribute"  xmlns:android="http://schemas.android.com/apk/res/android">
    <TextView
        style="@style/PlanAttributeText"
        android:id="@+id/attrib_name"
        android:textStyle="bold"/>
    <TextView
        style="@style/PlanAttributeText"
        android:id="@+id/attrib_value"
        android:gravity="right"
        android:textStyle="normal"/>
</TableRow>

Editing the path of the keystore file solved my problem.

I just now faced this issue while trying to restart XAMPP Apache.

What you can do to solve this is:

1. download PHP5.dll from http://originaldll.com/file/php5.dll/30704.html
2. Copy the downloaded php5.dll to C:\xampp\php
3. Start APACHE and MySql from XAMPP control panel

Hope my solution solves your problem.

Thank You!

The LoadBalancer ServiceType will only work if the underlying infrastructure supports the automatic creation of Load Balancers and have the respective support in Kubernetes, as is the case with the Google Cloud Platform and AWS. If no such feature is configured, the LoadBalancer IP address field is not populated and still in pending status , and the Service will work the same way as a NodePort type Service

i know its too late but anyone who came here for help now you can see this post .There are two options either use css/ JavaScript and if you use css it will be applicable to devices greater that 769px width for clickable top menu, that will be work perfectly f

See here for article

new allocates an amount of memory needed to store the object/array that you request. In this case n numbers of int.

The pointer will then store the address to this block of memory.

But be careful, this allocated block of memory will not be freed until you tell it so by writing

delete [] array;

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

max_allowed_packet is set in mysql config, not on php side

[mysqld]
max_allowed_packet=16M 

You can see it's curent value in mysql like this:

SHOW VARIABLES LIKE 'max_allowed_packet';

You can try to change it like this, but it's unlikely this will work on shared hosting:

SET GLOBAL max_allowed_packet=16777216;

You can read about it here http://dev.mysql.com/doc/refman/5.1/en/packet-too-large.html

EDIT

The [mysqld] is necessary to make the max_allowed_packet working since at least mysql version 5.5.

Recently setup an instance on AWS EC2 with Drupal and Solr Search Engine, which required 32M max_allowed_packet. It you set the value under [mysqld_safe] (which is default settings came with the mysql installation) mode in /etc/my.cnf, it did no work. I did not dig into the problem. But after I change it to [mysqld] and restarted the mysqld, it worked.

A Meteor app does not, by default, add any X-Powered-By headers to HTTP responses, as you might find in various PHP apps. The headers look like:

$ curl -I https://atmosphere.meteor.com  HTTP/1.1 200 OK content-type: text/html; charset=utf-8 date: Tue, 31 Dec 2013 23:12:25 GMT connection: keep-alive 

However, this doesn't mask that Meteor was used. Viewing the source of a Meteor app will look very distinctive.

<script type="text/javascript"> __meteor_runtime_config__ = {"meteorRelease":"0.6.3.1","ROOT_URL":"http://atmosphere.meteor.com","serverId":"62a4cf6a-3b28-f7b1-418f-3ddf038f84af","DDP_DEFAULT_CONNECTION_URL":"ddp+sockjs://ddp--****-atmosphere.meteor.com/sockjs"}; </script> 

If you're trying to avoid people being able to tell you are using Meteor even by viewing source, I don't think that's possible.

Actually there is a way to just white-list all nested parameters.

params.require(:widget).permit(:name, :description).tap do |whitelisted|
  whitelisted[:position] = params[:widget][:position]
  whitelisted[:properties] = params[:widget][:properties]
end

This method has advantage over other solutions. It allows to permit deep-nested parameters.

While other solutions like:

params.require(:person).permit(:name, :age, pets_attributes: [:id, :name, :category])

Don't.

Here is an example of a recursive algorithm for reversing a singly linked list. On a laptop with the following spec (4G memory, Intel Core i5 2.3GHz CPU, 64 bit Windows 7), this function will run into StackOverflow error for a linked list of size close to 10,000.

My point is that we should use recursion judiciously, always taking into account of the scale of the system. Often recursion can be converted to iterative program, which scales better. (One iterative version of the same algorithm is given at the bottom of the page, it reverses a singly linked list of size 1 million in 9 milliseconds.)

    private static LinkedListNode doReverseRecursively(LinkedListNode x, LinkedListNode first){

    LinkedListNode second = first.next;

    first.next = x;

    if(second != null){
        return doReverseRecursively(first, second);
    }else{
        return first;
    }

Adding on to the answer from @Ohmen, you could also add an external flag to create the data volume outside of docker compose. This way docker compose would not attempt to create it. Also you wouldn't have to worry about losing the data inside the data-volume in the event of $ docker-compose down -v. The below example is from the official page.

version: "3.8"

services:
  db:
    image: postgres
    volumes:
      - data:/var/lib/postgresql/data

volumes:
  data:
    external: true

Use RGB values combined with opacity to get the transparency that you wish.

For instance,

<div style=" background: rgb(255, 0, 0) ; opacity: 0.2;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.4;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.6;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.8;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 1;">&nbsp;</div>

Similarly, with actual values without opacity, will give the below.

<div style=" background: rgb(243, 191, 189) ; ">&nbsp;</div>
<div style=" background: rgb(246, 143, 142) ; ">&nbsp;</div>
<div style=" background: rgb(249, 95 , 94)  ; ">&nbsp;</div>
<div style=" background: rgb(252, 47, 47)   ; ">&nbsp;</div>
<div style=" background: rgb(255, 0, 0)     ; ">&nbsp;</div>

You can have a look at this WORKING EXAMPLE.

Now, if we specifically target your issue, here is the WORKING DEMO SPECIFIC TO YOUR ISSUE.

The HTML

<div class="social">
    <img src="http://www.google.co.in/images/srpr/logo4w.png" border="0" />
</div>

The CSS:

social img{
    opacity:0.5;
}
.social img:hover {
    opacity:1;
    background-color:black;
    cursor:pointer;
    background: rgb(255, 0, 0) ; opacity: 0.5;
}

Hope this helps Now.

If you have more than one version of Python and the script needs to run under a specific version, the she-bang can ensure the right one is used when the script is executed directly, for example:

#!/usr/bin/python2.7

Note the script could still be run via a complete Python command line, or via import, in which case the she-bang is ignored. But for scripts run directly, this is a decent reason to use the she-bang.

#!/usr/bin/env python is generally the better approach, but this helps with special cases.

Usually it would be better to establish a Python virtual environment, in which case the generic #!/usr/bin/env python would identify the correct instance of Python for the virtualenv.

Example:

<input 
  type="submit" 
  onclick="this.form.action='new_target.php?do=alternative_submit'" 
  value="Alternative Save"
/>

Voila. Very "fancy", three word JavaScript!

Do not inject javascript. That is a bad practice.

I would model the DatePicker as an element like textbox / select as shown below.

For the detailed answer - check here- http://www.testautomationguru.com/selenium-webdriver-automating-custom-controls-datepicker/

public class DatePicker {

    private static final String dateFormat = "dd MMM yyyy";

    @FindBy(css = "a.ui-datepicker-prev")
    private WebElement prev;

    @FindBy(css = "a.ui-datepicker-next")
    private WebElement next;

    @FindBy(css = "div.ui-datepicker-title")
    private WebElement curDate;

    @FindBy(css = "a.ui-state-default")
    private List < WebElement > dates;

    public void setDate(String date) {

        long diff = this.getDateDifferenceInMonths(date);
        int day = this.getDay(date);

        WebElement arrow = diff >= 0 ? next : prev;
        diff = Math.abs(diff);

        //click the arrows
        for (int i = 0; i < diff; i++)
            arrow.click();

        //select the date
        dates.stream()
            .filter(ele - > Integer.parseInt(ele.getText()) == day)
            .findFirst()
            .ifPresent(ele - > ele.click());

    }

    private int getDay(String date) {
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern(dateFormat);
        LocalDate dpToDate = LocalDate.parse(date, dtf);
        return dpToDate.getDayOfMonth();
    }

    private long getDateDifferenceInMonths(String date) {
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern(dateFormat);
        LocalDate dpCurDate = LocalDate.parse("01 " + this.getCurrentMonthFromDatePicker(), dtf);
        LocalDate dpToDate = LocalDate.parse(date, dtf);
        return YearMonth.from(dpCurDate).until(dpToDate, ChronoUnit.MONTHS);
    }

    private String getCurrentMonthFromDatePicker() {
        return this.curDate.getText();
    }

}

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

Please check out Crane (I'm the author)

SqlServerAccess sqlAccess = new SqlServerAccess("your connection string");
var result = sqlAccess.Command().ExecuteNonQuery("StoredProcedureName");

Also has a bunch of other features you might like.

I'd go for recursions:

l = ['a', 'b', 'c', 'd', 'e', ' ']
d = dict([(k, v) for k,v in zip (l[::2], l[1::2])])

This is because you have wrong selector. According to your markup, .ui-icon and .ui-icon-circle-triangle-w" should point to the same <span> element. So you should use:

$(".ui-icon.ui-icon-circle-triangle-w").html("<<");

or

$(".ui-datepicker-prev .ui-icon").html("<<");

or

$(".ui-datepicker-prev span").html("<<");

Iv'e noticed this recently with all new macs here at my office. Atom will be installed via an image for the developers but we found the Atom is never in the Application folder.

When doing a ls on the /usr/local/bin folder the path for atom will show something like "/private/var/folders/cs" . To resolve this, we just located atom.app and copied it into the application folder, then ran the system link commands provided by nwinkler which resoled the issue. Developers can now open atom from the command line with "atom" or open the current projects from their working director with "atom ."

You could also use CEILING which rounds up to an integer or desired multiple of significance

ie
=CEILING(A1,10)
rounds up to a multiple of 10

12340.0001 will become 12350

What Arne said - you can't reliably style select boxes and have them look anything like consistent across browsers.

Uniform: https://github.com/pixelmatrix/uniform is a javascript solution which gives you good graphic control over your form elements - it's still Javascript, but it's about as nice as javascript gets for solving this problem.

This is worked for me

1. npm uninstall @angular-devkit/build-angular
2. npm install @angular-devkit/[email protected]

I think because it's Standard's ver.

I don't know if you write your code in VS. But if you did, just go to ARCHITECTURE - new Diagram. & choose yours, & the VS 'll take the care of the rest :)

Couple of ways. Firstly, if you're adding a row each time a [de]activation occurs, you can set the column default to GETDATE() and not set the value in the insert. Otherwise,

UPDATE TableName SET [ColumnName] = GETDATE() WHERE UserId = @userId

I have been learning to think recursively and the first natural solution that struck me is as follows. A problem one step simpler would be to find permutations of a string that is one letter shorter. I will assume, and believe with every fiber of my being, that my function can correctly find permutations of a string that is one letter shorter than the one I am currently trying to.

Given a string say 'abc', break it into a subproblem of finding permutations of a string one character less which is 'bc'. Once we have permutations of 'bc' we need to know how to combine it with 'a' to get the permutations for 'abc'. This is the core of recursion. Use the solution of a subproblem to solve the current problem. By observation, we can see that inserting 'a' in all the positions of each of the permutations of 'bc' which are 'bc' and 'cb' will give us all the permutations of 'abc'. We have to insert 'a' between adjacent letters and at the front and end of each permutation. For example

For 'bc' we have

'a'+'bc' = 'abc'

'b'+'a'+'c' = 'bac'

'bc'+'a' = 'bca'

For 'cb' we have

'a'+'cb' = 'acb'

'c'+'a'+'b' = 'cab'

'cb'+'a' = 'cba'

The following code snippet will clarify this. Here is the working link for the snippet.

def main():
    result = []
    for permutation in ['bc', 'cb']:
        for i in range(len(permutation) + 1):
            result.append(permutation[:i] + 'a' + permutation[i:])
    return result


if __name__ == '__main__':
    print(main())

The complete recursive solution will be. Here is the working link for the complete code.

def permutations(s):
    if len(s) == 1 or len(s) == 0:
        return s
    _permutations = []
    for permutation in permutations(s[1:]):
        for i in range(len(permutation) + 1):
            _permutations.append(permutation[:i] + s[0] + permutation[i:])
    return _permutations


def main(s):
    print(permutations(s))


if __name__ == '__main__':
    main('abc')

You can use https://github.com/hughsk/flat

Take a nested Javascript object and flatten it, or unflatten an object with delimited keys.

Example from the doc

var flatten = require('flat')

flatten({
    key1: {
        keyA: 'valueI'
    },
    key2: {
        keyB: 'valueII'
    },
    key3: { a: { b: { c: 2 } } }
})

// {
//   'key1.keyA': 'valueI',
//   'key2.keyB': 'valueII',
//   'key3.a.b.c': 2
// }


var unflatten = require('flat').unflatten

unflatten({
    'three.levels.deep': 42,
    'three.levels': {
        nested: true
    }
})

// {
//     three: {
//         levels: {
//             deep: 42,
//             nested: true
//         }
//     }
// }

As proposed nanoTime () is very precise on short time scales. When this precision is required you need to take care about what you really measure. Especially not to measure the nanotime call itself

long start1 = System.nanoTime();
// maybe add here a call to a return to remove call up time, too.
// Avoid optimization 
long start2 = System.nanoTime();
myCall(); 
long stop = System.nanoTime();
long diff = stop - 2*start2 + start1;

System.out.println(diff + " ns");

By the way, you will measure different values for the same call due to

• other load on your computer (background, network, mouse movement, interrupts, task switching, threads)
• cache fillings (cold, warm)
• jit compiling (no optimization, performance hit due to running the compiler, performance boost due to compiler (but sometimes code with jit is slower than without!))
