Ben Alman has a good jquery querystring/url plugin here that allows you to manipulate the querystring easily.

As requested -

Goto his test page here

In firebug enter the following into the console

jQuery.param.querystring(window.location.href, 'a=3&newValue=100');

It will return you the following amended url string

http://benalman.com/code/test/js-jquery-url-querystring.html?a=3&b=Y&c=Z&newValue=100#n=1&o=2&p=3

Notice the a querystring value for a has changed from X to 3 and it has added the new value.

You can then use the new url string however you wish e.g using document.location = newUrl or change an anchor link etc

All the parameters after ? can be accessed using $_GET array. So,

echo $_GET['email'];

will extract the emails from urls.

Building on top of Mike Causer's answer I've made this function which takes into consideration multiple params with the same key (foo=bar&foo=baz) and also comma-separated parameters (foo=bar,baz,bin). It also lets you search for a certain query key.

function getQueryParams(queryKey) {
    var queryString = window.location.search;
    var query = {};
    var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
    for (var i = 0; i < pairs.length; i++) {
        var pair = pairs[i].split('=');
        var key = decodeURIComponent(pair[0]);
        var value = decodeURIComponent(pair[1] || '');
        // Se possui uma vírgula no valor, converter em um array
        value = (value.indexOf(',') === -1 ? value : value.split(','));

        // Se a key já existe, tratar ela como um array
        if (query[key]) {
            if (query[key].constructor === Array) {
                // Array.concat() faz merge se o valor inserido for um array
                query[key] = query[key].concat(value);
            } else {
                // Se não for um array, criar um array contendo o valor anterior e o novo valor
                query[key] = [query[key], value];
            }
        } else {
            query[key] = value;
        }
    }

    if (typeof queryKey === 'undefined') {
        return query;
    } else {
        return query[queryKey];
    }
}

Example input: foo.html?foo=bar&foo=baz&foo=bez,boz,buz&bar=1,2,3

Example output

{
    foo: ["bar","baz","bez","boz","buz"],
    bar: ["1","2","3"]
}

var obj = $.parseJSON(result);
for (var prop in obj) {
    alert(prop + " is " + obj[prop]);
}

try this way:

python -m pip install --user boto3

if ( ( param & karen ) == karen )
{
  // Do stuff
}

The bitwise 'and' will mask out everything except the bit that "represents" Karen. As long as each person is represented by a single bit position, you could check multiple people with a simple:

if ( ( param & karen ) == karen )
{
  // Do Karen's stuff
}
if ( ( param & bob ) == bob )
  // Do Bob's stuff
}

I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.

Make sure your computer is connected to the internet, then click on the link that comes with the error message i.e "install missing platform(s) and sync project". Give it a few seconds especially if your computer has low specs, it will bring up a window called SDK Quickfix Installation and everything is straightforward from there.

Not sure how efficient this might be in terms of performance, but this is what I use using array destructuring to keep everything nice and short:

const shareElements = (arr1, arr2) => {
  const typeArr = [...arr1, ...arr2]
  const typeSet = new Set(typeArr)
  return typeArr.length > typeSet.size
}

Since sets cannot have duplicate elements while arrays can, combining both input arrays, converting it to a set, and comparing the set size and array length would tell you if they share any elements.

The raw.githubusercontent.com domain is used to serve unprocessed versions of files stored in GitHub repositories. If you browse to a file on GitHub and then click the Raw link, that's where you'll go.

The URL in your question references the install file in the master branch of the Homebrew/install repository. The rest of that command just retrieves the file and runs ruby on its contents.

Yet another approach involves passing in a callback object or delegate that will operate on the value. If a value is not found, the callback is not called.

public void GetUserById(Guid id, UserCallback callback)
{
    // Lookup user
    if (userFound)
        callback(userEntity);  // or callback.Call(userEntity);
}

This works well when you want to avoid null checks all over your code, and when not finding a value isn't an error. You may also provide a callback for when no objects are found if you need any special processing.

public void GetUserById(Guid id, UserCallback callback, NotFoundCallback notFound)
{
    // Lookup user
    if (userFound)
        callback(userEntity);  // or callback.Call(userEntity);
    else
        notFound(); // or notFound.Call();
}

The same approach using a single object might look like:

public void GetUserById(Guid id, UserCallback callback)
{
    // Lookup user
    if (userFound)
        callback.Found(userEntity);
    else
        callback.NotFound();
}

From a design perspective, I really like this approach, but has the disadvantage of making the call site bulkier in languages that don't readily support first class functions.

Generic Extension method :

public static IEnumerable<TSource> Distinct<TSource>(this IEnumerable<TSource> source, IEqualityComparer<TSource> comparer)
{
    if (source == null)
        throw new ArgumentNullException(nameof(source));

    HashSet<TSource> set = new HashSet<TSource>(comparer);
    foreach (TSource item in source)
    {
        if (set.Add(item))
        {
            yield return item;
        }
    }
}

You can use click's confirm method.

import click

if click.confirm('Do you want to continue?', default=True):
    print('Do something')

This will print:

$ Do you want to continue? [Y/n]:

Should work for Python 2/3 on Linux, Mac or Windows.

For mysql you have limit, you can fire query as :

SELECT * FROM table limit 100` -- get 1st 100 records
SELECT * FROM table limit 100, 200` -- get 200 records beginning with row 101

For Oracle you can use rownum

See mysql select syntax and usage for limit here.

For SQLite, you have limit, offset. I haven't used SQLite but I checked it on SQLite Documentation. Check example for SQLite here.

You can't run the request from a browser, it will timeout waiting for the server running the CURL request to respond. The browser is probably timing out in 1-2 minutes, the default network timeout.

You need to run it from the command line/terminal.

Auto Complete Text box binding using Jquery

  ## HTML Code For Text Box and For Handling UserID use Hidden value ##
  <div class="ui-widget">
@Html.TextBox("userName")  
    @Html.Hidden("userId")
    </div>

Below Library's is Required

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<link rel="stylesheet" href="/resources/demos/style.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

Jquery Script

$("#userName").autocomplete(
{

    source: function (request,responce)
    {
        debugger
        var Name = $("#userName").val();

        $.ajax({
            url: "/Dashboard/UserNames",
            method: "POST",
            contentType: "application/json",
            data: JSON.stringify({
                Name: Name

            }),
            dataType: 'json',
            success: function (data) {
                debugger
                responce(data);
            },
            error: function (err) {
                alert(err);
            }
        });
    },
    select: function (event, ui) {

        $("#userName").val(ui.item.label); // display the selected text
        $("#userId").val(ui.item.value); // save selected id to hidden input
        return false;
    }
})

Return data Should be below format

 label = u.person_full_name,
 value = u.user_id

Give an id for the select object like this:

<select id="mySelect" name="val" size="1" >
    <option value="A">Apple</option>
    <option value="C">Cars</option>
    <option value="H">Honda</option>
    <option value="F">Fiat</option>
    <option value="I">Indigo</option>                    
</select> 

You can do it in pure JavaScript:

var selectobject = document.getElementById("mySelect");
for (var i=0; i<selectobject.length; i++) {
    if (selectobject.options[i].value == 'A')
        selectobject.remove(i);
}

But - as the other answers suggest - it's a lot easier to use jQuery or some other JS library.

curl -X PUT -T "/path/to/file" "http://myputserver.com/puturl.tmp"

Currency decimal separator can be different from Locale to another. It could be dangerous to consider . as separator always. i.e.

+------------------------------------+
¦    Locale      ¦      Sample       ¦
¦----------------+-------------------¦
¦ USA            ¦ $1,222,333.44 USD ¦
¦ United Kingdom ¦ £1.222.333,44 GBP ¦
¦ European       ¦ €1.333.333,44 EUR ¦
+------------------------------------+

I think the proper way is:

• Get decimal character via DecimalFormatSymbols by default Locale or specified one.
• Cook regex pattern with decimal character in order to obtain digits only

And here how I am solving it:

code:

import java.text.DecimalFormatSymbols;
import java.util.Locale;

    public static String getDigit(String quote, Locale locale) {
    char decimalSeparator;
    if (locale == null) {
        decimalSeparator = new DecimalFormatSymbols().getDecimalSeparator();
    } else {
        decimalSeparator = new DecimalFormatSymbols(locale).getDecimalSeparator();
    }

    String regex = "[^0-9" + decimalSeparator + "]";
    String valueOnlyDigit = quote.replaceAll(regex, "");
    try {
        return valueOnlyDigit;
    } catch (ArithmeticException | NumberFormatException e) {
        Log.e(TAG, "Error in getMoneyAsDecimal", e);
        return null;
    }
    return null;
}

I hope that may help,'.

Use the Git History Diff plugin for easy side-by-side branch diffing:

https://marketplace.visualstudio.com/items?itemName=huizhou.githd

Visit the link above and scroll down to the animated GIF image titled Diff Branch. You'll see you can easily pick any branch and do side-by-side comparison with the branch you are on! It is like getting a preview of what you will see in the GitHub Pull Request. For other Git stuff I prefer Visual Studio Code's built-in functionality or Git Lens as others have mentioned.

However, the above plugin is outstanding for doing branch diffing (i.e., for those doing a rebase Git flow and need to preview before a force push up to a GitHub PR).

I ran into something similar - I wanted to create a range based on some variables. Using the Worksheet.Cells did not work directly since I think the cell's values were passed to Range.

This did work though:

Range(Cells(1, 1).Address(), Cells(lastRow, lastColumn).Address()).Select

That took care of converting the cell's numerical location to what Range expects, which is the A1 format.

you need to use ++$counter, not $++counter, hence the reason it isn't working..

We can use replace to change the values in 'mpg' to NA that corresponds to cyl==4.

mtcars %>%
     mutate(mpg=replace(mpg, cyl==4, NA)) %>%
     as.data.frame()

It would appear that as of now (April of 2017) that the following works:

public string LoggedInUser => User.Identity.Name;

At least while within a Controller

@Valid in itself has nothing to do with Spring. It's part of Bean Validation specification(there are several of them, the latest one being JSR 380 as of second half of 2017), but @Valid is very old and derives all the way from JSR 303.

As we all know, Spring is very good at providing integration with all different JSRs and java libraries in general(think of JPA, JTA, Caching, etc.) and of course those guys took care of validation as well. One of the key components that facilitates this is MethodValidationPostProcessor.

Trying to answer your question - @Valid is very handy for so called validation cascading when you want to validate a complex graph and not just a top-level elements of an object. Every time you want to go deeper, you have to use @Valid. That's what JSR dictates. Spring will comply with that with some minor deviations(for example I tried putting @Validated instead of @Valid on RestController method and validation works, but the same will not apply for a regular "service" beans).

Using new ES6 Object.entries(), it makes for a fun little nested map/join:

const encodeGetParams = p => _x000D_
  Object.entries(p).map(kv => kv.map(encodeURIComponent).join("=")).join("&");_x000D_
_x000D_
const params = {_x000D_
  user: "María Rodríguez",_x000D_
  awesome: true,_x000D_
  awesomeness: 64,_x000D_
  "ZOMG+&=*(": "*^%*GMOZ"_x000D_
};_x000D_
_x000D_
console.log("https://example.com/endpoint?" + encodeGetParams(params))

if you have only one xml in your table, you can convert it in 2 steps:

CREATE TABLE Batches( 
   BatchID int,
   RawXml xml 
)

declare @xml xml=(select top 1 RawXml from @Batches)

SELECT  --b.BatchID,
        x.XmlCol.value('(ReportHeader/OrganizationReportReferenceIdentifier)[1]','VARCHAR(100)') AS OrganizationReportReferenceIdentifier,
        x.XmlCol.value('(ReportHeader/OrganizationNumber)[1]','VARCHAR(100)') AS OrganizationNumber
FROM    @xml.nodes('/CasinoDisbursementReportXmlFile/CasinoDisbursementReport') x(XmlCol)

You can use the test construct, [[ ]], along with the regular expression match operator, =~, to check if a string matches a regex pattern.

For your specific case, you can write:

[[ $date =~ ^[0-9]{8}$ ]] && echo "yes"

Or more a accurate test:

[[ $date =~ ^[0-9]{4}(0[1-9]|1[0-2])(0[1-9]|[1-2][0-9]|3[0-1])$ ]] && echo "yes"
#           |^^^^^^^^ ^^^^^^ ^^^^^^  ^^^^^^ ^^^^^^^^^^ ^^^^^^ |
#           |   |     ^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^^^^^^^^^^ |
#           |   |          |                   |              |
#           |   |           \                  |              |
#           | --year--   --month--           --day--          |
#           |          either 01...09      either 01..09     end of line
# start of line            or 10,11,12         or 10..29
#                                              or 30, 31

That is, you can define a regex in Bash matching the format you want. This way you can do:

[[ $date =~ ^regex$ ]] && echo "matched" || echo "did not match"

where commands after && are executed if the test is successful, and commands after || are executed if the test is unsuccessful.

Note this is based on the solution by Aleks-Daniel Jakimenko in User input date format verification in bash.

In other shells you can use grep. If your shell is POSIX compliant, do

(echo "$date" | grep -Eq  ^regex$) && echo "matched" || echo "did not match"

In fish, which is not POSIX-compliant, you can do

echo "$date" | grep -Eq "^regex\$"; and echo "matched"; or echo "did not match"

With log4j 1.x I find the best way is to use a DOMConfigurator to submit one of a predefined set of XML log configurations (say, one for normal use and one for debugging).

Making use of these can be done with something like this:

  public static void reconfigurePredefined(String newLoggerConfigName) {
    String name = newLoggerConfigName.toLowerCase();
    if ("default".equals(name)) {
      name = "log4j.xml";
    } else {
      name = "log4j-" + name + ".xml";
    }

    if (Log4jReconfigurator.class.getResource("/" + name) != null) {
      String logConfigPath = Log4jReconfigurator.class.getResource("/" + name).getPath();
      logger.warn("Using log4j configuration: " + logConfigPath);
      try (InputStream defaultIs = Log4jReconfigurator.class.getResourceAsStream("/" + name)) {
        new DOMConfigurator().doConfigure(defaultIs, LogManager.getLoggerRepository());
      } catch (IOException e) {
        logger.error("Failed to reconfigure log4j configuration, could not find file " + logConfigPath + " on the classpath", e);
      } catch (FactoryConfigurationError e) {
        logger.error("Failed to reconfigure log4j configuration, could not load file " + logConfigPath, e);
      }
    } else {
      logger.error("Could not find log4j configuration file " + name + ".xml on classpath");
    }
  }

Just call this with the appropriate config name, and make sure that you put the templates on the classpath.

If you really want to use a sed command without installing a new Python module, you could simply do the following:

import subprocess
subprocess.call("sed command")

If you are using version 1

Recaptcha.reload();

If you are using version 2

grecaptcha.reset();

You can try:

string s1 = Regex.Replace(s, "[^A-Za-z0-9 -]", "");

Where s is your string.

TableViewController1  ---segue--->   TableViewController2

You can change the text of the back button in either TableViewController1 or TableViewController2.

Change the back button text inside TableViewController1:

1) In viewWillAppear():

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    let myBackButton = UIBarButtonItem()
    myBackButton.title = "Custom text"
    navigationItem.backBarButtonItem = myBackButton
}

For some reason, viewDidLoad() is too early to add the back button to the NavigationItem. To connect the two TableViewControllers, in the storyboard control drag from the TableViewCell in TableViewController1 to the middle of TableViewController2 and in the popup menu select Selection Segue > Show.

2) In tableView(_:didSelectRowAt:):

override func tableView(_ tableView: UITableView, didSelectRowAt: IndexPath) {

    let myButton = UIBarButtonItem()
    myButton.title = "Custom text"
    navigationItem.backBarButtonItem = myButton

    performSegue(withIdentifier: "ShowMyCustomBackButton", sender: nil)
}

To connect the two TableViewControllers, in the storyboard control drag from the little yellow circle above TableViewController1 to the middle of TableViewController2 and from the popup menu select Manual Segue > Show. Then select the segue connecting the two TableViewControllers, and in the Attributes Inspector next to "Identifier" enter "ShowMyCustomBackButton".

3) In the storyboard:

If you just need static custom text for the back button, select the NavigationItem for TableViewController1 (it has a < for an icon in the storyboard’s table of contents), then open the Attributes Inspector and in the “Back Button” field enter your custom text (be sure to tab out of that field for the change to take effect).

Change the back button text inside TableViewController2:

1) In viewWillAppear():

class MySecondTableViewController: UITableViewController {

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        let myBackButton = UIBarButtonItem(
            title: "<Custom text",
            style: .plain,
            target: self,
            action: #selector(goBack)  //selector() needs to be paired with an @objc label on the method
        )

        navigationItem.leftBarButtonItem = myBackButton
    }

    @objc func goBack() {
        navigationController?.popViewController(animated: true)
    }

To connect the two TableViewControllers, in the storyboard control drag from the TableViewCell in TableViewController1 to the middle of TableViewController2 and in the popup menu select Selection Segue > Show.

$regex = '#<code>(.*?)</code>#';

Using # as the delimiter instead of / because then we don't need to escape the / in </code>

As Phoenix posted below, .*? is used to make the .* ("anything") match as few characters as possible before it comes across a </code> (known as a "non-greedy quantifier"). That way, if your string is

<code>hello</code> something <code>again</code>

you'll match hello and again instead of just matching hello</code> something <code>again.

Check your runtime tag inside the web.config, and verify you have something like this declared:

This is due to the fact that cv2 uses the type "uint8" from numpy. Therefore, you should define the type when creating the array.

Something like the following:

import numpy
import cv2

b = numpy.zeros([5,5,3], dtype=numpy.uint8)
b[:,:,0] = numpy.ones([5,5])*64
b[:,:,1] = numpy.ones([5,5])*128
b[:,:,2] = numpy.ones([5,5])*192

Since 2017 and Symfony 3.3 you can register Repository as service, with all its advantages it has.

Check my post How to use Repository with Doctrine as Service in Symfony for more general description.

To your specific case, original code with tuning would look like this:

1. Use in your services or Controller

<?php

namespace Test\CommonBundle\Services;

use Doctrine\ORM\EntityManagerInterface;

class UserService
{
    private $userRepository;

    // use custom repository over direct use of EntityManager
    // see step 2
    public function __constructor(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }

    public function getUser($userId)
    {
        return $this->userRepository->find($userId);
    }
}

2. Create new custom repository

<?php

namespace Test\CommonBundle\Repository;

use Doctrine\ORM\EntityManagerInterface;

class UserRepository
{
    private $repository;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->repository = $entityManager->getRepository(UserEntity::class);
    }

    public function find($userId)
    {
        return  $this->repository->find($userId);
    }
}

3. Register services

# app/config/services.yml
services:
    _defaults:
        autowire: true

    Test\CommonBundle\:
       resource: ../../Test/CommonBundle

PHP works only on server side, not on user host. Use JavaScript or jQuery to get this info and send via AJAX or URL (?x=1024&y=640).

$this->validate($request,[
        'input_field_name'=>'digits_between:2,5',
       ]);

Try this it will be work

Try to run dos2unix on your windows imported files first

Use these commands on a windows command prompt(cmd) with administrator privilege (run as administrator):

netsh wlan set hostednetwork mode=allow ssid=tests key=tests123

netsh wlan start hostednetwork

Then you go to Network and sharing center and click on "change adapter settings" (I'm using windows 7, it can be a little different on windows 8)

Then right click on the lan connection (internet connection that you are using), properties.

Click on sharing tab, select the wireless connection tests (the name tests you can change on the command line) and check "Allow other network users to connect through this network connection"

This done, your connection is ready to use!

For Blocks lover you can use ALActionBlocks to add action of gestures in block

__weak ALViewController *wSelf = self;
imageView.userInteractionEnabled = YES;
UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithBlock:^(UITapGestureRecognizer *weakGR) {
    NSLog(@"pan %@", NSStringFromCGPoint([weakGR locationInView:wSelf.view]));
}];
[self.imageView addGestureRecognizer:gr];

The problem with GCM is that there is a lot of configuration involved in the process:

• You have to add a lot of boilerplate to you Android app
• You need to configure an external server to comunicate with the GCM server
• You will have to write tests

If you like simple things (like me) you should try UrbanAirship. It is (IMHO) the easiest way to use GCM in your app without doing a lot of configuration. It also gives you a pretty GUI to test that your GCM messages are being delivered correctly.

• You can find the docs and getting started guide here
• You can find a sample application here

Note: I am not afiliated with UrbanAirship in any way

A reason for this problem (which is even harder to detect than the issue with char* str = "some string" - which others have explained) is when you are using constexpr.

constexpr char* str = "some string";

It seems that it would behave similar to const char* str, and so would not cause a warning, as it occurs before char*, but it instead behaves as char* const str.

Details

Constant pointer, and pointer to a constant. The difference between const char* str, and char* const str can be explained as follows.

1. const char* str : Declare str to be a pointer to a const char. This means that the data to which this pointer is pointing to it constant. The pointer can be modified, but any attempt to modify the data would throw a compilation error.
   1. str++ ; : VALID. We are modifying the pointer, and not the data being pointed to.
   2. *str = 'a'; : INVALID. We are trying to modify the data being pointed to.
2. char* const str : Declare str to be a const pointer to char. This means that point is now constant, but the data being pointed too is not. The pointer cannot be modified but we can modify the data using the pointer.
   1. str++ ; : INVALID. We are trying to modify the pointer variable, which is a constant.
   2. *str = 'a'; : VALID. We are trying to modify the data being pointed to. In our case this will not cause a compilation error, but will cause a runtime error, as the string will most probably will go into a read only section of the compiled binary. This statement would make sense if we had dynamically allocated memory, eg. char* const str = new char[5];.
3. const char* const str : Declare str to be a const pointer to a const char. In this case we can neither modify the pointer, nor the data being pointed to.
   1. str++ ; : INVALID. We are trying to modify the pointer variable, which is a constant.
   2. *str = 'a'; : INVALID. We are trying to modify the data pointed by this pointer, which is also constant.

In my case the issue was that I was expecting constexpr char* str to behave as const char* str, and not char* const str, since visually it seems closer to the former.

Also, the warning generated for constexpr char* str = "some string" is slightly different from char* str = "some string".

1. Compiler warning for constexpr char* str = "some string": ISO C++11 does not allow conversion from string literal to 'char *const'
2. Compiler warning for char* str = "some string": ISO C++11 does not allow conversion from string literal to 'char *'.

Tip

You can use C gibberish ? English converter to convert C declarations to easily understandable English statements, and vice versa. This is a C only tool, and thus wont support things (like constexpr) which are exclusive to C++.

I have read all answers, but this link was more clear explanation for me about difference between CPU(Processor) and Core. So I'm leaving here some notes from there.

The main difference between CPU and Core is that the CPU is an electronic circuit inside the computer that carries out instruction to perform arithmetic, logical, control and input/output operations while the core is an execution unit inside the CPU that receives and executes instructions.

vector<char> toVector( const std::string& s ) {
  string s = "apple";  
  vector<char> v(s.size()+1);
  memcpy( &v.front(), s.c_str(), s.size() + 1 );
  return v;
}
vector<char> v = toVector(std::string("apple"));

// what you were looking for (mutable)
char* c = v.data();

.c_str() works for immutable. The vector will manage the memory for you.

CentOS is Linux, so as in just about all other Unix/Linux systems, you have the find command. To search for files within the current directory:

find -name "filename"

You can also have wildcards inside the quotes, and not just a strict filename. You can also explicitly specify a directory to start searching from as the first argument to find:

find / -name "filename"

will look for "filename" or all the files that match the regex expression in between the quotes, starting from the root directory. You can also use single quotes instead of double quotes, but in most cases you don't need either one, so the above commands will work without any quotes as well. Also, for example, if you're searching for java files and you know they are somewhere in your /home/username, do:

find /home/username -name *.java

There are many more options to the find command and you should do a:

man find

to learn more about it.

One more thing: if you start searching from / and are not root or are not sudo running the command, you might get warnings that you don't have permission to read certain directories. To ignore/remove those, do:

find / -name 'filename' 2>/dev/null

That just redirects the stderr to /dev/null.

If you're running a CentOS container, you can install ps using this command:

yum install -y procps

Running this command on Dockerfile:

RUN yum install -y procps

You need to set Div2 to Div1's innerHTML. Also, JavaScript is case sensitive - in your HTML, the id Div2 is DIV2. Also, you should use document, not Document:

var MyDiv1 = document.getElementById('DIV1');
var MyDiv2 = document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML; 

Here is a JSFiddle: http://jsfiddle.net/gFN6r/.

I think the easiest (and maybe most elegant) solution here is to leverage the fact that you can set default to a callable. So, to get around admin's special handling of auto_now, you can just declare the field like so:

from django.utils import timezone
date_field = models.DateField(default=timezone.now)

It's important that you don't use timezone.now() as the default value wouldn't update (i.e., default gets set only when the code is loaded). If you find yourself doing this a lot, you could create a custom field. However, this is pretty DRY already I think.

if (string.IsNullOrEmpty(myString)) {
   //
}

JLabel label = new JLabel("Hello World");
label.setFont(new Font("Calibri", Font.BOLD, 20));

Here is a good article on creating and adding a class library. Even shows how to create Methods through the method wizard and how to use it in the application

For googler, I wrote a simple Stateless Widget containing 3 method mentioned in this SO. Hope this make it easier to understand.

import 'package:flutter/material.dart';

class ListAndFP extends StatelessWidget {
  final List<String> items = ['apple', 'banana', 'orange', 'lemon'];

  //  for in (require dart 2.2.2 SDK or later)
  Widget method1() {
    return Column(
      children: <Widget>[
        Text('You can put other Widgets here'),
        for (var item in items) Text(item),
      ],
    );
  }

  // map() + toList() + Spread Property
  Widget method2() {
    return Column(
      children: <Widget>[
        Text('You can put other Widgets here'),
        ...items.map((item) => Text(item)).toList(),
      ],
    );
  }

  // map() + toList()
  Widget method3() {
    return Column(
      // Text('You CANNOT put other Widgets here'),
      children: items.map((item) => Text(item)).toList(),
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: method1(),
    );
  }
}

This problem started when I upgraded to .NET Core 1.1.0

Solved by adding the following dependency to the project.json of the test project:

"Microsoft.DotNet.InternalAbstractions": "1.0.500-preview2-1-003177"

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

Links to relevant Microsoft documentation (for PowerShell 5.0; tho versions 3.0 and 4.0 are also available at the links):

• about_Scripts
• about_Functions
• about_Functions_Advanced_Parameters

For Python 3 above, use:

sudo apt-get install python3-dateutil

Have only tried this on Mac:

• Create a data directory in the root folder of your app
• cd into your wherever you placed your mongo directory when you installed it

• run this command:

  mongod --dbpath ~/path/to/your/app/data

You should be good to go!

You may try:

    $('#GridName').data('kendoGrid').dataSource.read();
$('#GridName').data('kendoGrid').refresh();

You can create an alias to open a file in your default editor by appending the following line to your .gitconfig file:

edit = "!f() { $(git config core.editor) -- $@; }; f"

Then, git edit foo.txt will open the file foo.txt for editing.

It's much easier to open .gitconfig with git config --global --edit and paste the line, rather than figure out how to escape all the characters to enter the alias directly from the command line with git config alias.edit "..."

How it works

• ! starts a bash command, not an internal git command
• f() {...}; starts a function
• $(git config core.editor) will get the name of your editor, from the local config, or the global if the local is not set. Unfortunately it will not look in $VISUAL or $EDITOR for this, if none is set.
• -- separates the editor command with the file list. This works for most command line editors, so is safer to put in. If skipped and the core.editor is not set then it is possible that an executable file is executed instead of being edited. With it here, the command will just fail.
• $@ will add the files entered at the command line.
• f will execute the function after it is defined.

Use case

The other answers express doubt as to why you would want this. My use case is that I want to edit files as part of other git functions that I am building, and I want to edit them in the same editor that the user has configured. For example, the following is one of my aliases:

reedit = "!f() { $(git config core.editor) -- $(git diff --name-only $1); }; f"

Then, git reedit will open all the files that I have already started modifying, and git reedit --cached will open all the staged files.

As @Super9 told about OPENDATASOURCE using SQL Server Authentication with data provider SQLOLEDB . I am just posting here a code snippet for one table is in the current sever database where the code is running and another in other server '192.166.41.123'

SELECT top 2 * from dbo.tblHamdoonSoft  tbl1 inner JOIN  
OpenDataSource('SQLOLEDB','Data Source=192.166.41.123;User ID=sa;Password=hamdoonsoft')
.[TestDatabase].[dbo].[tblHamdoonSoft1] tbl2 on tbl1.id = tbl2.id

I see what you are trying to do, you are trying to use the <body> tag as the container for the main content of the page. Instead, use the <main> tag, as specified in the HTML5 spec. I use this layout:

    <!DOCTYPE html>
    <html>
        <head> *Metadata* </head>
        <body>
            <header>
                *<h1> and other important stuff </h1>*
                <nav> *Usually a formatted <Ul>* </nav>
            </header>
            <main> *All my content* </main>
            <footer> *Copyright, links, social media etc* </footer>
        </body>
    </html>

I'm not 100% sure but I think that anything outside the <body> tag is considered metadata and will not be rendered by the browser. I don't think that the DOM can access it either.

To conclude, use the <main> tag for your content and keep formatting your HTML the correct way as you have in your first code snippet. You used the <section> tag but I think that comes with some weird formatting issues when you try to apply CSS.

I know this is an old post, but for the newbies like myself who still hit this page this might be useful. when you hover on a method you get a non clickable info-box whereas if you just write a comma in the method parenthesis the IntelliSense will offer you the beloved info-box with the clickable arrows.

Solution for ajax pages that continuously load data. The previews methods stated do not work. What we can do instead is grab the page dom and hash it and compare old and new hash values together over a delta time.

import time
from selenium import webdriver

def page_has_loaded(driver, sleep_time = 2):
    '''
    Waits for page to completely load by comparing current page hash values.
    '''

    def get_page_hash(driver):
        '''
        Returns html dom hash
        '''
        # can find element by either 'html' tag or by the html 'root' id
        dom = driver.find_element_by_tag_name('html').get_attribute('innerHTML')
        # dom = driver.find_element_by_id('root').get_attribute('innerHTML')
        dom_hash = hash(dom.encode('utf-8'))
        return dom_hash

    page_hash = 'empty'
    page_hash_new = ''
    
    # comparing old and new page DOM hash together to verify the page is fully loaded
    while page_hash != page_hash_new: 
        page_hash = get_page_hash(driver)
        time.sleep(sleep_time)
        page_hash_new = get_page_hash(driver)
        print('<page_has_loaded> - page not loaded')

    print('<page_has_loaded> - page loaded: {}'.format(driver.current_url))

To update an entity with Entity Framework Core, this is the logical process:

1. Create instance for DbContext class
2. Retrieve entity by key
3. Make changes on entity's properties
4. Save changes

Update() method in DbContext:

Begins tracking the given entity in the Modified state such that it will be updated in the database when SaveChanges() is called.

Update method doesn't save changes in database; instead, it sets states for entries in DbContext instance.

So, We can invoke Update() method before to save changes in database.

I'll assume some object definitions to answer your question:

1. Database name is Store

2. Table name is Product

Product class definition:

public class Product
{
    public int? ProductID { get; set; }
    
    public string ProductName { get; set; }
    
    public string Description { get; set; }
    
    public decimal? UnitPrice { get; set; }
}

DbContext class definition:

public class StoreDbContext : DbContext
{
    public DbSet<Product> Products { get; set; }
    
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer("Your Connection String");

        base.OnConfiguring(optionsBuilder);
    }
    
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Order>(entity =>
        {
            // Set key for entity
            entity.HasKey(p => p.ProductID);
        });
        
        base.OnModelCreating(modelBuilder);
    }
}

Logic to update entity:

using (var context = new StoreDbContext())
{
        // Retrieve entity by id
        // Answer for question #1
        var entity = context.Products.FirstOrDefault(item => item.ProductID == id);
        
        // Validate entity is not null
        if (entity != null)
        {
            // Answer for question #2

            // Make changes on entity
            entity.UnitPrice = 49.99m;
            entity.Description = "Collector's edition";
            
            /* If the entry is being tracked, then invoking update API is not needed. 
              The API only needs to be invoked if the entry was not tracked. 
              https://www.learnentityframeworkcore.com/dbcontext/modifying-data */
            // context.Products.Update(entity);
            
            // Save changes in database
            context.SaveChanges();
        }
}

I know this is an old question, but this is still a problem I keep walking into, and yet there is still no clear solution to do this correctly when using async/await in an async void signature method.

However, I noticed that .Wait() is working properly inside the void method.

and since async void and void have the same signature, you might need to do the following.

void LoadBlahBlah()
{
    blah().Wait(); //this blocks
}

Confusingly enough async/await does not block on the next code.

async void LoadBlahBlah()
{
    await blah(); //this does not block
}

When you decompile your code, my guess is that async void creates an internal Task (just like async Task), but since the signature does not support to return that internal Tasks

this means that internally the async void method will still be able to "await" internally async methods. but externally unable to know when the internal Task is complete.

So my conclusion is that async void is working as intended, and if you need feedback from the internal Task, then you need to use the async Task signature instead.

hopefully my rambling makes sense to anybody also looking for answers.

Edit: I made some example code and decompiled it to see what is actually going on.

static async void Test()
{
    await Task.Delay(5000);
}

static async Task TestAsync()
{
    await Task.Delay(5000);
}

Turns into (edit: I know that the body code is not here but in the statemachines, but the statemachines was basically identical, so I didn't bother adding them)

private static void Test()
{
    <Test>d__1 stateMachine = new <Test>d__1();
    stateMachine.<>t__builder = AsyncVoidMethodBuilder.Create();
    stateMachine.<>1__state = -1;
    AsyncVoidMethodBuilder <>t__builder = stateMachine.<>t__builder;
    <>t__builder.Start(ref stateMachine);
}
private static Task TestAsync()
{
    <TestAsync>d__2 stateMachine = new <TestAsync>d__2();
    stateMachine.<>t__builder = AsyncTaskMethodBuilder.Create();
    stateMachine.<>1__state = -1;
    AsyncTaskMethodBuilder <>t__builder = stateMachine.<>t__builder;
    <>t__builder.Start(ref stateMachine);
    return stateMachine.<>t__builder.Task;
}

neither AsyncVoidMethodBuilder or AsyncTaskMethodBuilder actually have any code in the Start method that would hint of them to block, and would always run asynchronously after they are started.

meaning without the returning Task, there would be no way to check if it is complete.

as expected, it only starts the Task running async, and then it continues in the code. and the async Task, first it starts the Task, and then it returns it.

so I guess my answer would be to never use async void, if you need to know when the task is done, that is what async Task is for.

Perhaps you need to know how urls are mapped too, since I suffered 404 for hours. There are two kinds of handlers handling requests. BeanNameUrlHandlerMapping and SimpleUrlHandlerMapping. When we defined a servlet-mapping, we are using SimpleUrlHandlerMapping. One thing we need to know is these two handlers share a common property called alwaysUseFullPath which defaults to false.

false here means Spring will not use the full path to mapp a url to a controller. What does it mean? It means when you define a servlet-mapping:

<servlet-mapping>
    <servlet-name>viewServlet</servlet-name>
    <url-pattern>/perfix/*</url-pattern>
</servlet-mapping>

the handler will actually use the * part to find the controller. For example, the following controller will face a 404 error when you request it using /perfix/api/feature/doSomething

@Controller()
@RequestMapping("/perfix/api/feature")
public class MyController {
    @RequestMapping(value = "/doSomething", method = RequestMethod.GET) 
    @ResponseBody
    public String doSomething(HttpServletRequest request) {
        ....
    }
}

It is a perfect match, right? But why 404. As mentioned before, default value of alwaysUseFullPath is false, which means in your request, only /api/feature/doSomething is used to find a corresponding Controller, but there is no Controller cares about that path. You need to either change your url to /perfix/perfix/api/feature/doSomething or remove perfix from MyController base @RequestingMapping.

It may not work for you if you use localhost/info.php.

You may be able to found the clue from the error. Find the port number in the error message. To me it was 80. I changed address as http://localhost:80/info.php, and then it worked to me.

There is no reflection in C++. True. But if the compiler can't provide you the metadata you need, you can provide it yourself.

Let's start by making a property struct:

template<typename Class, typename T>
struct PropertyImpl {
    constexpr PropertyImpl(T Class::*aMember, const char* aName) : member{aMember}, name{aName} {}

    using Type = T;

    T Class::*member;
    const char* name;
};

template<typename Class, typename T>
constexpr auto property(T Class::*member, const char* name) {
    return PropertyImpl<Class, T>{member, name};
}

Of course, you also can have a property that takes a setter and getter instead of a pointer to member, and maybe read only properties for calculated value you'd like to serialize. If you use C++17, you can extend it further to make a property that works with lambdas.

Ok, now we have the building block of our compile-time introspection system.

Now in your class Dog, add your metadata:

struct Dog {
    std::string barkType;
    std::string color;
    int weight = 0;

    bool operator==(const Dog& rhs) const {
        return std::tie(barkType, color, weight) == std::tie(rhs.barkType, rhs.color, rhs.weight);
    }

    constexpr static auto properties = std::make_tuple(
        property(&Dog::barkType, "barkType"),
        property(&Dog::color, "color"),
        property(&Dog::weight, "weight")
    );
};

We will need to iterate on that list. To iterate on a tuple, there are many ways, but my preferred one is this:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    using unpack_t = int[];
    (void)unpack_t{(static_cast<void>(f(std::integral_constant<T, S>{})), 0)..., 0};
}

If C++17 fold expressions are available in your compiler, then for_sequence can be simplified to:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    (static_cast<void>(f(std::integral_constant<T, S>{})), ...);
}

This will call a function for each constant in the integer sequence.

If this method don't work or gives trouble to your compiler, you can always use the array expansion trick.

Now that you have the desired metadata and tools, you can iterate through the properties to unserialize:

// unserialize function
template<typename T>
T fromJson(const Json::Value& data) {
    T object;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // get the type of the property
        using Type = typename decltype(property)::Type;

        // set the value to the member
        // you can also replace `asAny` by `fromJson` to recursively serialize
        object.*(property.member) = Json::asAny<Type>(data[property.name]);
    });

    return object;
}

And for serialize:

template<typename T>
Json::Value toJson(const T& object) {
    Json::Value data;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // set the value to the member
        data[property.name] = object.*(property.member);
    });

    return data;
}

If you want recursive serialization and unserialization, you can replace asAny by fromJson.

Now you can use your functions like this:

Dog dog;

dog.color = "green";
dog.barkType = "whaf";
dog.weight = 30;

Json::Value jsonDog = toJson(dog); // produces {"color":"green", "barkType":"whaf", "weight": 30}
auto dog2 = fromJson<Dog>(jsonDog);

std::cout << std::boolalpha << (dog == dog2) << std::endl; // pass the test, both dog are equal!

Done! No need for run-time reflection, just some C++14 goodness!

This code could benefit from some improvement, and could of course work with C++11 with some ajustements.

Note that one would need to write the asAny function. It's just a function that takes a Json::Value and call the right as... function, or another fromJson.

Here's a complete, working example made from the various code snippet of this answer. Feel free to use it.

As mentionned in the comments, this code won't work with msvc. Please refer to this question if you want a compatible code: Pointer to member: works in GCC but not in VS2015

In Java size of array is fixed , but you can add elements dynamically to a fixed sized array using its index and for loop. Please find example below.

public class SimpleJava {

    /**

    public static void main(String[] args) {
        // TODO code application logic here

        try{
            String[] transactions;
            transactions = new String[10];

            for(int i = 0; i < transactions.length; i++){
                transactions[i] = "transaction - "+Integer.toString(i);            
            }

            System.out.println(Arrays.toString(transactions));

        }catch(Exception exc){
            System.out.println(exc.getMessage());
            System.out.println(Arrays.toString(exc.getStackTrace()));
        }
    }

jQuery.fn is defined shorthand for jQuery.prototype. From the source code:

jQuery.fn = jQuery.prototype = {
    // ...
}

That means jQuery.fn.jquery is an alias for jQuery.prototype.jquery, which returns the current jQuery version. Again from the source code:

// The current version of jQuery being used
jquery: "@VERSION",

File.Create returns a FileStream object that you can call Close() on.

CLI has some limit when ouput is displayed. I suggest to export output into local file:

$hive -e 'show partitions table;' > partitions

The compiler only knows that the code is or isn't reachable if you use "return". Think of Environment.Exit() as a function that you call, and the compiler don't know that it will close the application.

Little late... I had to respond. This is the simplest way.

Step by step. .padEnd - Guarentees the length of the string

"The padEnd() method pads the current string with a given string (repeated, if needed) so that the resulting string reaches a given length. The padding is applied from the end (right) of the current string. The source for this interactive example is stored in a GitHub repository." source: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

.substring - limits to the length you need

If you choose to add ellipses, append them to the output.

I gave 4 examples of common JavaScript usages. I highly recommend using the String prototype with Overloading for legacy support. It makes it much easier to implement and change later.

I arrived to this question looking for the same but for Chromium (actually I'm using https://ungoogled-software.github.io). So in case anyone else is looking for the same:

1. Go to chrome://flags/
2. Search for Handling of extension MIME type requests
3. Select Always prompt for install
4. Search for an extension and copy its URL (something like https://chrome.google.com/webstore/detail/...)
5. Paste the URL in https://crxextractor.com/ and download the .CRX
6. Voilà, Chromium will prompt for installation

I feel your pain as I, too, am starting out to get Django and React.js working together. Did a couple of Django projects, and I think, React.js is a great match for Django. However, it can be intimidating to get started. We are standing on the shoulders of giants here ;)

Here's how I think, it all works together (big picture, please someone correct me if I'm wrong).

• Django and its database (I prefer Postgres) on one side (backend)
• Django Rest-framework providing the interface to the outside world (i.e. Mobile Apps and React and such)
• Reactjs, Nodejs, Webpack, Redux (or maybe MobX?) on the other side (frontend)

Communication between Django and 'the frontend' is done via the Rest framework. Make sure you get your authorization and permissions for the Rest framework in place.

I found a good boiler template for exactly this scenario and it works out of the box. Just follow the readme https://github.com/scottwoodall/django-react-template and once you are done, you have a pretty nice Django Reactjs project running. By no means this is meant for production, but rather as a way for you to dig in and see how things are connected and working!

One tiny change I'd like to suggest is this: Follow the setup instructions BUT before you get to the 2nd step to setup the backend (Django here https://github.com/scottwoodall/django-react-template/blob/master/backend/README.md), change the requirements file for the setup.

You'll find the file in your project at /backend/requirements/common.pip Replace its content with this

appdirs==1.4.0
Django==1.10.5
django-autofixture==0.12.0
django-extensions==1.6.1
django-filter==1.0.1
djangorestframework==3.5.3
psycopg2==2.6.1

this gets you the latest stable version for Django and its Rest framework.

I hope that helps.

I had a similar problem, but I was getting an error message

cannot execute binary file

I discovered that the filename contained non-ASCII characters. When those were fixed, the script ran fine with ./script.sh.

What no-one seems to realize is that none of the System.Uri constructors correctly handles certain paths with percent signs in them.

new Uri(@"C:\%51.txt").AbsoluteUri;

This gives you "file:///C:/Q.txt" instead of "file:///C:/%2551.txt".

Neither values of the deprecated dontEscape argument makes any difference, and specifying the UriKind gives the same result too. Trying with the UriBuilder doesn't help either:

new UriBuilder() { Scheme = Uri.UriSchemeFile, Host = "", Path = @"C:\%51.txt" }.Uri.AbsoluteUri

This returns "file:///C:/Q.txt" as well.

As far as I can tell the framework is actually lacking any way of doing this correctly.

We can try to it by replacing the backslashes with forward slashes and feed the path to Uri.EscapeUriString - i.e.

new Uri(Uri.EscapeUriString(filePath.Replace(Path.DirectorySeparatorChar, '/'))).AbsoluteUri

This seems to work at first, but if you give it the path C:\a b.txt then you end up with file:///C:/a%2520b.txt instead of file:///C:/a%20b.txt - somehow it decides that some sequences should be decoded but not others. Now we could just prefix with "file:///" ourselves, however this fails to take UNC paths like \\remote\share\foo.txt into account - what seems to be generally accepted on Windows is to turn them into pseudo-urls of the form file://remote/share/foo.txt, so we should take that into account as well.

EscapeUriString also has the problem that it does not escape the '#' character. It would seem at this point that we have no other choice but making our own method from scratch. So this is what I suggest:

public static string FilePathToFileUrl(string filePath)
{
  StringBuilder uri = new StringBuilder();
  foreach (char v in filePath)
  {
    if ((v >= 'a' && v <= 'z') || (v >= 'A' && v <= 'Z') || (v >= '0' && v <= '9') ||
      v == '+' || v == '/' || v == ':' || v == '.' || v == '-' || v == '_' || v == '~' ||
      v > '\xFF')
    {
      uri.Append(v);
    }
    else if (v == Path.DirectorySeparatorChar || v == Path.AltDirectorySeparatorChar)
    {
      uri.Append('/');
    }
    else
    {
      uri.Append(String.Format("%{0:X2}", (int)v));
    }
  }
  if (uri.Length >= 2 && uri[0] == '/' && uri[1] == '/') // UNC path
    uri.Insert(0, "file:");
  else
    uri.Insert(0, "file:///");
  return uri.ToString();
}

This intentionally leaves + and : unencoded as that seems to be how it's usually done on Windows. It also only encodes latin1 as Internet Explorer can't understand unicode characters in file urls if they are encoded.

You have to encode your parameters.

Something like this will do:

import java.net.*;
import java.io.*;

public class EncodeParameter { 

    public static void main( String [] args ) throws URISyntaxException ,
                                         UnsupportedEncodingException   { 

        String myQuery = "^IXIC";

        URI uri = new URI( String.format( 
                           "http://finance.yahoo.com/q/h?s=%s", 
                           URLEncoder.encode( myQuery , "UTF8" ) ) );

        System.out.println( uri );

    }
}

http://java.sun.com/javase/6/docs/api/java/net/URLEncoder.html

By sorting the array, you get the first and last values for min / max.

import java.util.Arrays;

public class apples {

  public static void main(String[] args) {
    int a[] = {2,5,3,7,8};
    Arrays.sort(a);

    int min =a[0];
    System.out.println(min);

    int max= a[a.length-1];
    System.out.println(max);
  }
    
}

Although the sorting operation is more expensive than simply finding min/max values with a simple loop. But when performance is not a concern (e.g. small arrays, or your the cost is irrelevant for your application), it is a quite simple solution.

Note: the array also gets modified after this.

<ImageView
    android:id="@+id/img"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center" />

In objective-C, go ahead and create a category method off of the UIView class.

- (void)removeAllSubviews
{
    for (UIView *subview in self.subviews)
        [subview removeFromSuperview];
}

df.filter((df.bar != 'a') & (df.bar != 'b'))

Follow this steps:

-Build
-Generate Signed Apk
-Create new

Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)

You are probably storing the value 0xc0 in a char variable, what is probably a signed type, and your value is negative (most significant bit set). Then, when printing, it is converted to int, and to keep the semantical equivalence, the compiler pads the extra bytes with 0xff, so the negative int will have the same numerical value of your negative char. To fix this, just cast to unsigned char when printing:

printf("%x", (unsigned char)variable);

I found using SendGrid to be the easiest way to set up sending email with Django. Here's how it works:

1. Create a SendGrid account (and verify your email)
2. Add the following to your settings.py: EMAIL_HOST = 'smtp.sendgrid.net' EMAIL_HOST_USER = '<your sendgrid username>' EMAIL_HOST_PASSWORD = '<your sendgrid password>' EMAIL_PORT = 587 EMAIL_USE_TLS = True

And you're all set!

To send email:

from django.core.mail import send_mail
send_mail('<Your subject>', '<Your message>', '[email protected]', ['[email protected]'])

If you want Django to email you whenever there's a 500 internal server error, add the following to your settings.py:

DEFAULT_FROM_EMAIL = '[email protected]'
ADMINS = [('<Your name>', '[email protected]')]

Sending email with SendGrid is free up to 12k emails per month.

These are the steps to install MongoDB as Windows Service :

1. Create a log directory, e.g. C:\MongoDB\log

2. Create a db directory, e.g. C:\MongoDB\db

3. Prepare a configuration file with following lines

   dbpath=C:\MongoDB\db

   logpath=C:\MongoDB\log

   Place the configuration file with name mongod.cfg in folder "C:\MongoDB\"

4. Following command will install the Windows Service on your sc.exe create MongoDB binPath= "\"C:\MongoDB\Server\3.4\bin\mongod.exe\" --service --config=\"C:\MongoDB\mongod.cfg\" DisplayName= "MongoDB 3.4" start= "auto"

5. Once you run this command, you will get the [SC] CreateService SUCCESS

6. Run following command on Command Prompt

   net start MongoDB

Does it have to be an actual service? Can you just use the built in scheduled tasks in the windows control panel.

sed -i 's/[[:blank:]]\{1,\}$//' YourFile

[:blank:] is for space, tab mainly and {1,} to exclude 'no space at the end' of the substitution process (no big significant impact if line are short and file are small)

This is probably not faster, and definitely not very readable. So, for the sake of colorful solutions...

int i = array.length()-1;
for(; i > -1 && array[i]; i--);
return i==-1

'[{"event":"inbound","ts":1426249238}]' is a string, you cannot access any properties there. You will have to parse it to an object, with JSON.parse() and then handle it like a normal object

If that's the entire log4j.properties file it looks like you're never actually creating a logger. You need a line like:

log4j.rootLogger=debug,A1

I've used the Visual Studio extension "Full Rename Project" to successfully rename projects in an ASP.NET Core 2 solution.

I used ReSharper then to adjust the namespace (right click on project, refactor, adjust namespaces...)

https://github.com/kuanysh-nabiyev/RenameProjectVsExtension

It Work for me if i use ChangeDetectorRef in Angular 9

@ViewChild('search', {static: false})
public searchElementRef: ElementRef;

constructor(private changeDetector: ChangeDetectorRef) {}

//then call this when this.display = true;
show() {
   this.display = true;
   this.changeDetector.detectChanges();
}

In simple, Normalisation is Reduction of Redundancies.
Examples of Redundancies:
a) white spaces outside of the root/document tags(...<document></document>...)
b) white spaces within start tag (<...>) and end tag (</...>)
c) white spaces between attributes and their values (ie. spaces between key name and =")
d) superfluous namespace declarations
e) line breaks/white spaces in texts of attributes and tags
f) comments etc...

I use Kate (KDE Advanced Text Editor) for most of my development, including Django. It has both a Python and Django Templates syntax higlighting. I switch to Quanta+ when a significant part of the project involves HTML.

Since it uses Kate's KPart, it's just as good for editing the Python parts, and for the HTML templates i have the whole Quanta+ tools, while still highligting Django-specific tags.

Update 2013: Unfortunately, Quanta+ has been dead for years now, and there's no hope that it will ever be resurrected. Also, there's no other usable HTML editor out there, so it's Kate all the time now.

To solve the problem I use ${string_prompt} variable. It shows a input dialog when application runs. I can set the date/time manually at that dialog.

1. Move cursor at the end of file path.

2. Click variables and select string_prompt

3. Select Apply and Run

You need to have access as well on the site that you will be iframing. i found the best solution here: https://gist.github.com/MateuszFlisikowski/91ff99551dcd90971377

yourotherdomain.html

<script type='text/javascript' src="js/jquery.min.js"></script>
<script type='text/javascript'>
  // Size the parent iFrame
  function iframeResize() {
    var height = $('body').outerHeight(); // IMPORTANT: If body's height is set to 100% with CSS this will not work.
    parent.postMessage("resize::"+height,"*");
  }

  $(document).ready(function() {
    // Resize iframe
    setInterval(iframeResize, 1000);
  });
</script>

your website with iframe

<iframe src='example.html' id='edh-iframe'></iframe>
<script type='text/javascript'>
  // Listen for messages sent from the iFrame
  var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
  var eventer = window[eventMethod];
  var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";

  eventer(messageEvent,function(e) {
    // If the message is a resize frame request
    if (e.data.indexOf('resize::') != -1) {
      var height = e.data.replace('resize::', '');
      document.getElementById('edh-iframe').style.height = height+'px';
    }
  } ,false);
</script>

This worked well for me.

Button Style

<Style x:Key="TransparentStyle" TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border>
                    <Border.Style>
                        <Style TargetType="{x:Type Border}">
                            <Style.Triggers>
                                <Trigger Property="IsMouseOver" Value="True">
                                    <Setter Property="Background" Value="DarkGoldenrod"/>
                                </Trigger>
                            </Style.Triggers>
                        </Style>
                    </Border.Style>
                    <Grid Background="Transparent">
                        <ContentPresenter></ContentPresenter>
                    </Grid>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Button

<Button Style="{StaticResource TransparentStyle}" VerticalAlignment="Top" HorizontalAlignment="Right" Width="25" Height="25"
        Command="{Binding CloseWindow}">
    <Button.Content >
        <Grid Margin="0 0 0 0">
            <Path Data="M0,7 L10,17 M0,17 L10,7" Stroke="Blue" StrokeThickness="2" HorizontalAlignment="Center" Stretch="None" />
        </Grid>
    </Button.Content>
</Button>

Notes

• The button displays a little blue cross, much like the one used to close a window.
• By setting the background of the grid to "Transparent", it adds a hittest, which means that if the mouse is anywhere over the button, then it will work. Omit this tag, and the button will only light up if the mouse is over one of the vector lines in the icon (this is not very usable).

2019 Update

There are various ways to handle this more elegantly now. Please see some other answers on this thread. Tech moves fast so answers can often become out of date fairly quickly. My answer will still work but it's worth looking at alternatives as well.

2012 Answer

Using your code, the issue is that you haven't waited for a socket to be assigned to the request before attempting to set stuff on the socket object. It's all async so:

var options = { ... }
var req = http.request(options, function(res) {
  // Usual stuff: on(data), on(end), chunks, etc...
});

req.on('socket', function (socket) {
    socket.setTimeout(myTimeout);  
    socket.on('timeout', function() {
        req.abort();
    });
});

req.on('error', function(err) {
    if (err.code === "ECONNRESET") {
        console.log("Timeout occurs");
        //specific error treatment
    }
    //other error treatment
});

req.write('something');
req.end();

The 'socket' event is fired when the request is assigned a socket object.

Have you tried adding the semicolon to onclick="googleMapsQuery(422111);". I don't have enough of your code to test if the missing semicolon would cause the error, but ie is more picky about syntax.

I like to add this method, if you are using an edit form, you can use this code to save the changes in your update(Request $request, $id) function:

$post = Post::find($id);    
$post->fill($request->input())->save();

keep in mind that you have to name your inputs with the same column name. The fill() function will do all the work for you :)

I don't have a windows box handy to try this but I think you can use a DataView and do something like so:

DataView view = new DataView(ds.Tables["MyTable"]);
view.RowFilter = "MyValue = 42"; // MyValue here is a column name

// Delete these rows.
foreach (DataRowView row in view)
{
  row.Delete();
}

I haven't tested this, though. You might give it a try.

In addition to excellent Craig Ringer's post and depesz's blog post, if you would like to speed up your inserts through ODBC (psqlodbc) interface by using prepared-statement inserts inside a transaction, there are a few extra things you need to do to make it work fast:

1. Set the level-of-rollback-on-errors to "Transaction" by specifying Protocol=-1 in the connection string. By default psqlodbc uses "Statement" level, which creates a SAVEPOINT for each statement rather than an entire transaction, making inserts slower.
2. Use server-side prepared statements by specifying UseServerSidePrepare=1 in the connection string. Without this option the client sends the entire insert statement along with each row being inserted.
3. Disable auto-commit on each statement using SQLSetConnectAttr(conn, SQL_ATTR_AUTOCOMMIT, reinterpret_cast<SQLPOINTER>(SQL_AUTOCOMMIT_OFF), 0);
4. Once all rows have been inserted, commit the transaction using SQLEndTran(SQL_HANDLE_DBC, conn, SQL_COMMIT);. There is no need to explicitly open a transaction.

Unfortunately, psqlodbc "implements" SQLBulkOperations by issuing a series of unprepared insert statements, so that to achieve the fastest insert one needs to code up the above steps manually.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

To turn off axes for all subplots, do either:

[axi.set_axis_off() for axi in ax.ravel()]

or

map(lambda axi: axi.set_axis_off(), ax.ravel())

SELECT

If you dont want your local changes, then do below command to ignore(delete permanently) the local changes.

• If its unstaged changes, then do checkout (git checkout <filename> or git checkout -- .)
• If its staged changes, then first do reset (git reset <filename> or git reset) and then do checkout (git checkout <filename> or git checkout -- .)
• If it is untracted files/folders (newly created), then do clean (git clean -fd)

If you dont want to loose your local changes, then stash it and do pull or rebase. Later merge your changes from stash.

• Do git stash, and then get latest changes from repo git pull orign master or git rebase origin/master, and then merge your changes from stash git stash pop stash@{0}

You can try to set_time_limit(n). However, if your PHP setup is running in safe mode, you can only change it from the php.ini file.

I think you might be better off using PHP's inbuilt filters - in this particular case:

It can return a true or false when supplied with the FILTER_VALIDATE_EMAIL param.

The signature of main method must be

public static void main(String[] args) 

• The parameter's name can be any valid name
• The positions of static and public keywords can be interchanged
• The String array can use also the varargs syntax

A class can define multiple methods with the name main. The signature of these methods does not match the signature of the main method. These other methods with different signatures are not considered the "main" method.

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

I see that this question is already old but still...

We made a sipmle library at our company for achieving what is desired - An interactive info window with views and everything. You can check it out on github.

I hope it helps :)

Here is a simple approach which will print the 2 different elapsed time for each query.

DECLARE @t1 DATETIME;
DECLARE @t2 DATETIME;

SET @t1 = GETDATE();
SELECT DISTINCT u.profession FROM users u; --Query with DISTINCT
SET @t2 = GETDATE();
PRINT 'Elapsed time (ms): ' + CAST(DATEDIFF(millisecond, @t1, @t2) AS varchar);

SET @t1 = GETDATE();
SELECT u.profession FROM users u GROUP BY u.profession; --Query with GROUP BY
SET @t2 = GETDATE();
PRINT 'Elapsed time (ms): ' + CAST(DATEDIFF(millisecond, @t1, @t2) AS varchar);

OR try SET STATISTICS TIME (Transact-SQL)

SET STATISTICS TIME ON;
SELECT DISTINCT u.profession FROM users u; --Query with DISTINCT
SELECT u.profession FROM users u GROUP BY u.profession; --Query with GROUP BY
SET STATISTICS TIME OFF;

It simply displays the number of milliseconds required to parse, compile, and execute each statement as below:

 SQL Server Execution Times:
   CPU time = 0 ms,  elapsed time = 2 ms.

Well one way to do it would be to just put a class on the "parent" rows and remove all the ids and inline onclick attributes:

<table id="products">
    <thead>
    <tr>
        <th>Product</th>
        <th>Price</th>
        <th>Destination</th>
        <th>Updated on</th>
    </tr>
    </thead>
    <tbody>
    <tr class="parent">
        <td>Oranges</td>
        <td>100</td>
        <td><a href="#">+ On Store</a></td>
        <td>22/10</td>
    </tr>
    <tr>
        <td></td>
        <td>120</td>
        <td>City 1</td>
        <td>22/10</td>
    </tr>
    <tr>
        <td></td>
        <td>140</td>
        <td>City 2</td>
        <td>22/10</td>
    </tr>
    ...etc.
    </tbody>
</table>

And then have some CSS that hides all non-parents:

tbody tr {
    display : none;          // default is hidden
}
tr.parent {
    display : table-row;     // parents are shown
}
tr.open {
    display : table-row;     // class to be given to "open" child rows
}

That greatly simplifies your html. Note that I've added <thead> and <tbody> to your markup to make it easy to hide data rows and ignore heading rows.

With jQuery you can then simply do this:

// when an anchor in the table is clicked
$("#products").on("click","a",function(e) {
    // prevent default behaviour
    e.preventDefault();
    // find all the following TR elements up to the next "parent"
    // and toggle their "open" class
    $(this).closest("tr").nextUntil(".parent").toggleClass("open");
});

Demo: http://jsfiddle.net/CBLWS/1/

Or, to implement something like that in plain JavaScript, perhaps something like the following:

document.getElementById("products").addEventListener("click", function(e) {
    // if clicked item is an anchor
    if (e.target.tagName === "A") {
        e.preventDefault();
        // get reference to anchor's parent TR
        var row = e.target.parentNode.parentNode;
        // loop through all of the following TRs until the next parent is found
        while ((row = nextTr(row)) && !/\bparent\b/.test(row.className))
            toggle_it(row);
    }
});

function nextTr(row) {
    // find next sibling that is an element (skip text nodes, etc.)
    while ((row = row.nextSibling) && row.nodeType != 1);
    return row;
}

function toggle_it(item){ 
     if (/\bopen\b/.test(item.className))       // if item already has the class
         item.className = item.className.replace(/\bopen\b/," "); // remove it
     else                                       // otherwise
         item.className += " open";             // add it
}

Either way, put the JavaScript in a <script> element that is at the end of the body, so that it runs after the table has been parsed.

Recall that in Dijkstra's algorithm, once a vertex is marked as "closed" (and out of the open set) -it assumes that any node originating from it will lead to greater distance so, the algorithm found the shortest path to it, and will never have to develop this node again, but this doesn't hold true in case of negative weights.

In gitk --all:

• right click on the commit you want
• -> create new branch
• enter the name of an existing branch
• press return on the dialog that confirms replacing the old branch of that name.

Beware that re-creating instead of modifying the existing branch will lose tracking-branch information. (This is generally not a problem for simple use-cases where there's only one remote and your local branch has the same name as the corresponding branch in the remote. See comments for more details, thanks @mbdevpl for pointing out this downside.)

It would be cool if gitk had a feature where the dialog box had 3 options: overwrite, modify existing, or cancel.

Even if you're normally a command-line junkie like myself, git gui and gitk are quite nicely designed for the subset of git usage they allow. I highly recommend using them for what they're good at (i.e. selectively staging hunks into/out of the index in git gui, and also just committing. (ctrl-s to add a signed-off: line, ctrl-enter to commit.)

gitk is great for keeping track of a few branches while you sort out your changes into a nice patch series to submit upstream, or anything else where you need to keep track of what you're in the middle of with multiple branches.

I don't even have a graphical file browser open, but I love gitk/git gui.

Have you looked into ControlsFx Popover control.

import org.controlsfx.control.PopOver;
import org.controlsfx.control.PopOver.ArrowLocation;

private PopOver item;

final Scene scene = addItemButton.getScene();

final Point2D windowCoord = new Point2D(scene.getWindow()
        .getX(), scene.getWindow().getY());

final Point2D sceneCoord = new Point2D(scene.getX(), scene.
                getY());

final Point2D nodeCoord = addItemButton.localToScene(0.0,
                        0.0);
final double clickX = Math.round(windowCoord.getX()
    + sceneCoord.getY() + nodeCoord.getX());

final double clickY = Math.round(windowCoord.getY()
        + sceneCoord.getY() + nodeCoord.getY());
item.setContentNode(addItemScreen);
item.setArrowLocation(ArrowLocation.BOTTOM_LEFT);
item.setCornerRadius(4);                            
item.setDetachedTitle("Add New Item");
item.show(addItemButton.getParent(), clickX, clickY);

This is only an example but a PopOver sounds like it could accomplish what you want. Check out the documentation for more info.

Important note: ControlsFX will only work on JavaFX 8.0 b118 or later.

@Alwin Doss You should provide the -L option before -l. You would have done the other way round probably. Try this :)

Load it into Reflector and see what it references?

for example:

Despite this question being rather old, I had to deal with a similar warning and wanted to share what I found out.

First of all this is a warning and not an error. So there is no need to worry too much about it. Basically it means, that Tomcat does not know what to do with the source attribute from context.

This source attribute is set by Eclipse (or to be more specific the Eclipse Web Tools Platform) to the server.xml file of Tomcat to match the running application to a project in workspace.

Tomcat generates a warning for every unknown markup in the server.xml (i.e. the source attribute) and this is the source of the warning. You can safely ignore it.

This can be confusing for anyone using nodejs for the first time. It is actually possible to pipe your node console output to the browser console. Take a look at connect-browser-logger on github

UPDATE: As pointed out by Yan, connect-browser-logger appears to be defunct. I would recommend NodeMonkey as detailed here : Output to Chrome console from Node.js

class Student{
    //instance variable or data members.

    Map<Integer, List<Object>> mapp = new HashMap<Integer, List<Object>>();
    Scanner s1 = new Scanner(System.in);
    String name = s1.nextLine();
    int regno ;
    int mark1;
    int mark2;
    int total;
    List<Object> list = new ArrayList<Object>();
    mapp.put(regno,list); //what wrong in this part?
    list.add(mark1);
    list.add(mark2);**
    //String mark2=mapp.get(regno)[2];
}

Applying inline-block to the element that is to be centered and applying text-align:center to the parent block did the trick for me.

Works even on <span> tags.

You need to save the PID of the background process at the time you start it:

foo &
FOO_PID=$!
# do other stuff
kill $FOO_PID

You cannot use job control, since that is an interactive feature and tied to a controlling terminal. A script will not necessarily have a terminal attached at all so job control will not necessarily be available.

<div id="normal>text..</div>
<div id="small1" class="smallDiv"></div>
<div id="small2" class="smallDiv"></div>
<div id="small3" class="smallDiv"></div>

css:

.smallDiv { height: 150px; width: 150px; }

I cannot comment on the top answers to say this: I would like to add an explicit point which is only implied in the top answers:

The non-capturing group (?...) does not remove any characters from the original full match, it only reorganises the regex visually to the programmer.

To access a specific part of the regex without defined extraneous characters you would always need to use .group(<index>)

The other people made very nice answers, but I would like to complete their work with an extra development tool. It is called Live HTTP Headers and you can install it into your Firefox, and in Chrome we have the same plug in like this.

Working with it is queit easy.

1. Using your Firefox, navigate to the website which you want to get your post request to it.

2. In your Firefox menu Tools->Live Http Headers

3. A new window pop ups for you, and all the http method details would be saved in this window for you. You don't need to do anything in this step.

4. In the website, do an activity(log in, submit a form, etc.)

5. Look at your plug in window. It is all recorded.

Just remember you need to check the Capture.

It is happened to me with laravel 5.1 on php-7 when I was running bunch of unitests.

The solution was - to change memory_limit in php.ini but it should be correct one. So you need one responsible for server, located there:

/etc/php/7.0/cli/php.ini

so you need a line with

 memory_limit

After that you need to restart php service

sudo service php7.0-fpm restart

to check if it was changed successfully I used command line to run this:

 php -i

the report contained following line

memory_limit => 2048M => 2048M

Now test cases are fine.

@tennisgent's solution is great. However, I think is a little limited.

Modularity and Encapsulation in Angular goes beyond routes. Based on the way the web is moving towards component-based development, it is important to apply this in directives as well.

As you already know, in Angular we can include templates (structure) and controllers (behavior) in pages and components. AngularCSS enables the last missing piece: attaching stylesheets (presentation).

For a full solution I suggest using AngularCSS.

1. Supports Angular's ngRoute, UI Router, directives, controllers and services.
2. Doesn't required to have ng-app in the <html> tag. This is important when you have multiple apps running on the same page
3. You can customize where the stylesheets are injected: head, body, custom selector, etc...
4. Supports preloading, persisting and cache busting
5. Supports media queries and optimizes page load via matchMedia API

https://github.com/door3/angular-css

Here are some examples:

Routes

  $routeProvider
    .when('/page1', {
      templateUrl: 'page1/page1.html',
      controller: 'page1Ctrl',
      /* Now you can bind css to routes */
      css: 'page1/page1.css'
    })
    .when('/page2', {
      templateUrl: 'page2/page2.html',
      controller: 'page2Ctrl',
      /* You can also enable features like bust cache, persist and preload */
      css: {
        href: 'page2/page2.css',
        bustCache: true
      }
    })
    .when('/page3', {
      templateUrl: 'page3/page3.html',
      controller: 'page3Ctrl',
      /* This is how you can include multiple stylesheets */
      css: ['page3/page3.css','page3/page3-2.css']
    })
    .when('/page4', {
      templateUrl: 'page4/page4.html',
      controller: 'page4Ctrl',
      css: [
        {
          href: 'page4/page4.css',
          persist: true
        }, {
          href: 'page4/page4.mobile.css',
          /* Media Query support via window.matchMedia API
           * This will only add the stylesheet if the breakpoint matches */
          media: 'screen and (max-width : 768px)'
        }, {
          href: 'page4/page4.print.css',
          media: 'print'
        }
      ]
    });

Directives

myApp.directive('myDirective', function () {
  return {
    restrict: 'E',
    templateUrl: 'my-directive/my-directive.html',
    css: 'my-directive/my-directive.css'
  }
});

Additionally, you can use the $css service for edge cases:

myApp.controller('pageCtrl', function ($scope, $css) {

  // Binds stylesheet(s) to scope create/destroy events (recommended over add/remove)
  $css.bind({ 
    href: 'my-page/my-page.css'
  }, $scope);

  // Simply add stylesheet(s)
  $css.add('my-page/my-page.css');

  // Simply remove stylesheet(s)
  $css.remove(['my-page/my-page.css','my-page/my-page2.css']);

  // Remove all stylesheets
  $css.removeAll();

});

The proper data type for "2010-12-20 00:00:00.0000000" value is DATETIME2(7) / DT_DBTIME2 ().

But used data type for CYCLE_DATE field is DATETIME - DT_DATE. This means milliseconds precision with accuracy down to every third millisecond (yyyy-mm-ddThh:mi:ss.mmL where L can be 0,3 or 7).

The solution is to change CYCLE_DATE date type to DATETIME2 - DT_DBTIME2.

You call tarfile.open with mode='w:gz', meaning "Open for gzip compressed writing."

You'll probably want to end the filename (the name argument to open) with .tar.gz, but that doesn't affect compression abilities.

BTW, you usually get better compression with a mode of 'w:bz2', just like tar can usually compress even better with bzip2 than it can compress with gzip.

As mentioned above, the following link gives you the specific country code to allow Java to localize the number. Every country has its own style.

In the link above you will find the country code which should be placed in here:

...(new Locale(<COUNTRY CODE HERE>));

Switzerland for example formats the numbers as follows:

1000.00 --> 1'000.00

country code

To achieve this, following codes works for me:

NumberFormat nf = NumberFormat.getNumberInstance(new Locale("de","CH"));
nf.setMaximumFractionDigits(2);
DecimalFormat df = (DecimalFormat)nf;
System.out.println(df.format(1000.00));

Result is as expected:

1'000.00

I just want to mention a thing, there are many tools can do text processing, e.g. sort, cut, split, join, paste, comm, uniq, column, rev, tac, tr, nl, pr, head, tail.....

they are very handy but you have to learn their options etc.

A lazy way (not the best way) to learn text processing might be: only learn grep , sed and awk. with this three tools, you can solve almost 99% of text processing problems and don't need to memorize above different cmds and options. :)

AND, if you 've learned and used the three, you knew the difference. Actually, the difference here means which tool is good at solving what kind of problem.

a more lazy way might be learning a script language (python, perl or ruby) and do every text processing with it.

The same can be done without DataTrigger too:

 <DataGrid.RowStyle>
     <Style TargetType="DataGridRow">
         <Setter Property="Background" >
             <Setter.Value>
                 <Binding Path="State" Converter="{StaticResource BooleanToBrushConverter}">
                     <Binding.ConverterParameter>
                         <x:Array Type="SolidColorBrush">
                             <SolidColorBrush Color="{StaticResource RedColor}"/>
                             <SolidColorBrush Color="{StaticResource TransparentColor}"/>
                         </x:Array>
                     </Binding.ConverterParameter>
                 </Binding>
             </Setter.Value>
         </Setter>
     </Style>
 </DataGrid.RowStyle>

Where BooleanToBrushConverter is the following class:

public class BooleanToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value == null)
            return Brushes.Transparent;

        Brush[] brushes = parameter as Brush[];
        if (brushes == null)
            return Brushes.Transparent;

        bool isTrue;
        bool.TryParse(value.ToString(), out isTrue);

        if (isTrue)
        {
            var brush =  (SolidColorBrush)brushes[0];
            return brush ?? Brushes.Transparent;
        }
        else
        {
            var brush = (SolidColorBrush)brushes[1];
            return brush ?? Brushes.Transparent;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

It is technically possible to put a caption on an ImageButton if you really want to do it. Just put a TextView over the ImageButton using FrameLayout. Just remember to not make the Textview clickable.

Example:

<FrameLayout>
    <ImageButton
        android:id="@+id/button_x"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@null"
        android:scaleType="fitXY"
        android:src="@drawable/button_graphic" >
    </ImageButton>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:clickable="false"
        android:text="TEST TEST" >
    </TextView>
</FrameLayout>

Just happened to me after upgrading to Android Studio 3.1. The Offline Work checkbox was unchecked, so no luck there.

I went to Settings > Build, Execution, Deployment > Compiler and the Command-line Options textfield contained --offline, so I just deleted that and everything worked.

You can replicate those brackets in the left join:

LEFT JOIN bookings  
               ON rooms.id = bookings.room_type_id
              AND (  bookings.arrival between ? and ?
                  OR bookings.departure between ? and ? )

is

->leftJoin('bookings', function($join){
    $join->on('rooms.id', '=', 'bookings.room_type_id');
    $join->on(DB::raw('(  bookings.arrival between ? and ? OR bookings.departure between ? and ? )'), DB::raw(''), DB::raw(''));
})

You'll then have to set the bindings later using "setBindings" as described in this SO post: How to bind parameters to a raw DB query in Laravel that's used on a model?

It's not pretty but it works.

You need to click Log Navigator icon (far right in left sidebar). Then choose your Debug/Run session in left sidebar, and you will have console in editor area.

Compatible with all SDK versions (android.permission.ACCESS_FINE_LOCATION became dangerous permission in Android M and requires user to manually grant it).

In Android versions below Android M ContextCompat.checkSelfPermission(...) always returns true if you add these permission(s) in AndroidManifest.xml)

public void onSomeButtonClick() {
    ...
    if (!permissionsGranted()) {
        ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, 123);
    } else doLocationAccessRelatedJob();
    ...
}

private Boolean permissionsGranted() {
    return ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
}

@Override
public void onRequestPermissionsResult(final int requestCode, @NonNull final String[] permissions, @NonNull final int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == 123) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Permission granted.
            doLocationAccessRelatedJob();
        } else {
            // User refused to grant permission. You can add AlertDialog here
            Toast.makeText(this, "You didn't give permission to access device location", Toast.LENGTH_LONG).show();
            startInstalledAppDetailsActivity();
        }
    }
}

private void startInstalledAppDetailsActivity() {
    Intent i = new Intent();
    i.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
    i.addCategory(Intent.CATEGORY_DEFAULT);
    i.setData(Uri.parse("package:" + getPackageName()));
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(i);
}

in AndroidManifest.xml:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Using gson it is much simpler. Use following code snippet:

 // create a new Gson instance
 Gson gson = new Gson();
 // convert your list to json
 String jsonCartList = gson.toJson(cartList);
 // print your generated json
 System.out.println("jsonCartList: " + jsonCartList);

Converting back from JSON string to your Java object

 // Converts JSON string into a List of Product object
 Type type = new TypeToken<List<Product>>(){}.getType();
 List<Product> prodList = gson.fromJson(jsonCartList, type);

 // print your List<Product>
 System.out.println("prodList: " + prodList);

KnexJs can be used as an SQL query builder in both Node.JS and the browser. I find it easy to use. Let try it - Knex.js

$ npm install knex --save
# Then add one of the following (adding a --save) flag:
$ npm install pg
$ npm install sqlite3
$ npm install mysql
$ npm install mysql2
$ npm install mariasql
$ npm install strong-oracle
$ npm install oracle
$ npm install mssql


var knex = require('knex')({
  client: 'mysql',
  connection: {
    host : '127.0.0.1',
    user : 'your_database_user',
    password : 'your_database_password',
    database : 'myapp_test'
  }
});

You can use it like this

knex.select('*').from('users')

or

knex('users').where({
  first_name: 'Test',
  last_name:  'User'
}).select('id')

scroll at particular position
and this helped me alot. by click listener you can get the position in your adapter

layoutmanager.scrollToPosition(int position);

You can do:

<hr style="border: 1px dashed black;" />

As seen in the revision column of the Android SDK Manager, the latest published version of the Support Library is 22.2.1. You'll have to wait until 23.0.0 is published.

Edit: API 23 is already published. So u can use 23.0.0

Semicolon in the interpreter

Having read the answers, I still miss one important aspect of using semicolons, possibly the only one where it really makes a difference...

When you're working in an interpreter REPL (the Python interactive shell, IDLE, ipython) the value of the last expression is printed to the screen and usually this is the intended behavior.

Using an expression for side effects

But in some cases you want to evaluate an expression for its side effects only, e.g., to see the results of your simulation plotted by matplotlib.

In this cases you (probably) don't want to see the screenful of reprs of matplotlib objects that are sometimes returned by a call to a matplotlib function and, in IPython at least, one of the possibilities you have is to append a semicolon to the overly verbose statement, now IPython sees the input line as composed by two expressions, the matplotlib invocation and a null statement, so that the value of the compound expression is None and nothing is printed to the screen by the interpreter (the other possibility being assignment, as in _ = plot(...) but I find that a bit more intrusive).

Personal remark

IMHO, the use of the semicolon to suppress not desired output in the interpreter has become more relevant following the introduction of the IPyton notebook, that permits to save the input and the output, including graphical output, of an interpreter session for documentation and eventual reuse.

You can use the built-in forEach function for arrays.

Like this:

//this sets all product descriptions to a max length of 10 characters
data.products.forEach( (element) => {
    element.product_desc = element.product_desc.substring(0,10);
});

Your version wasn't wrong though. It should look more like this:

for(let i=0; i<data.products.length; i++){
    console.log(data.products[i].product_desc); //use i instead of 0
}

To add to @Hima's answer, if you want to modify a current x or y limit you could use the following.

import numpy as np # you probably alredy do this so no extra overhead
fig, axes = plt.subplot()
axes.plot(data[:,0], data[:,1])
xlim = axes.get_xlim()
# example of how to zoomout by a factor of 0.1
factor = 0.1 
new_xlim = (xlim[0] + xlim[1])/2 + np.array((-0.5, 0.5)) * (xlim[1] - xlim[0]) * (1 + factor) 
axes.set_xlim(new_xlim)

I find this particularly useful when I want to zoom out or zoom in just a little from the default plot settings.

Ansible has a version_compare filter since 1.6. You can do something like below in when conditional:

when: ansible_distribution_version | version_compare('12.04', '>=')

This will give you support for major & minor versions comparisons and you can compare versions using operators like:

<, lt, <=, le, >, gt, >=, ge, ==, =, eq, !=, <>, ne

You can find more information about this here: Ansible - Version comparison filters

Otherwise if you have really simple case you can use what @ProfHase85 suggested

It means it's a decimal literal, as others have said. However, the origins are probably not those suggested elsewhere in this answer. From the C# Annotated Standard (the ECMA version, not the MS version):

The decimal suffix is M/m since D/d was already taken by double. Although it has been suggested that M stands for money, Peter Golde recalls that M was chosen simply as the next best letter in decimal.

A similar annotation mentions that early versions of C# included "Y" and "S" for byte and short literals respectively. They were dropped on the grounds of not being useful very often.

Try this:

INSERT INTO test_table (SELECT null,txt FROM test_table)

Every time you run this query, This will insert all the rows again with new ids. values in your table and will increase exponentially.

I used a table with two columns i.e id and txt and id is auto increment.

In a typical application there is a UITabBarController and it embeds 3 or more UIViewController as its tabs. In such a case if you subclassed a UITabBarController as YourTabBarController then you can set the selected index simply by:

selectedIndex = 1 // Displays 2nd tab. The index starts from 0.

In case you are navigating to YourTabBarController from any other view, then in that view controller's prepare(for segue:) method you can do:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destination.
        // Pass the selected object to the new view controller.
        if segue.identifier == "SegueToYourTabBarController" {
            if let destVC = segue.destination as? YourTabBarController {
                destVC.selectedIndex = 0
            }
        }

I am using this way of setting tab with Xcode 10 and Swift 4.2.

You need make sure to start the session at the top of every PHP file where you want to use the $_SESSION superglobal. Like this:

<?php
  session_start();
  echo $_SESSION['youritem'];
?>

You forgot the Session HELPER.

Consider it as an array of arrays and this will work for sure.

                {32, 33, 39, 50, 51, 89},
              };


    for(int i=0; i<mat.length; i++) {
        for(int j=0; j<mat[i].length; j++) {
            System.out.println("Values at arr["+i+"]["+j+"] is "+mat[i][j]);
        }

How can I create a branch on a remote repository?

Assuming that you have cloned your remote repository from some single remote repository.

# create a new branch locally
git branch name_of_branch
git checkout name_of_branch
# edit/add/remove files    
# ... 
# Commit your changes locally
git add fileName
git commit -m Message
# push changes and new branch to remote repository:
git push origin name_of_branch:name_of_branch

Here is the full working code to download all files (with wildcard or file extension) from the FTP site to local directory. Set the variable values.

    #FTP Server Information - SET VARIABLES
    $ftp = "ftp://XXX.com/" 
    $user = 'UserName' 
    $pass = 'Password'
    $folder = 'FTP_Folder'
    $target = "C:\Folder\Folder1\"

    #SET CREDENTIALS
    $credentials = new-object System.Net.NetworkCredential($user, $pass)

    function Get-FtpDir ($url,$credentials) {
        $request = [Net.WebRequest]::Create($url)
        $request.Method = [System.Net.WebRequestMethods+FTP]::ListDirectory
        if ($credentials) { $request.Credentials = $credentials }
        $response = $request.GetResponse()
        $reader = New-Object IO.StreamReader $response.GetResponseStream() 
        while(-not $reader.EndOfStream) {
            $reader.ReadLine()
        }
        #$reader.ReadToEnd()
        $reader.Close()
        $response.Close()
    }

    #SET FOLDER PATH
    $folderPath= $ftp + "/" + $folder + "/"

    $files = Get-FTPDir -url $folderPath -credentials $credentials

    $files 

    $webclient = New-Object System.Net.WebClient 
    $webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass) 
    $counter = 0
    foreach ($file in ($files | where {$_ -like "*.txt"})){
        $source=$folderPath + $file  
        $destination = $target + $file 
        $webclient.DownloadFile($source, $target+$file)

        #PRINT FILE NAME AND COUNTER
        $counter++
        $counter
        $source
    }

If still not working you can call garbage collector to close the file and free up memory

System.gc();
if(new File("./__tmp.txt").delete()){
    System.out.println("OK");
}

Don't forget to close that file, if any previous opening using code snippet fio.close() I tested in Java 1.8, works well.

You can still get not-a-number (NaN) values from simple arithmetic involving inf:

>>> 0 * float("inf")
nan

Note that you will normally not get an inf value through usual arithmetic calculations:

>>> 2.0**2
4.0
>>> _**2
16.0
>>> _**2
256.0
>>> _**2
65536.0
>>> _**2
4294967296.0
>>> _**2
1.8446744073709552e+19
>>> _**2
3.4028236692093846e+38
>>> _**2
1.157920892373162e+77
>>> _**2
1.3407807929942597e+154
>>> _**2
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
OverflowError: (34, 'Numerical result out of range')

The inf value is considered a very special value with unusual semantics, so it's better to know about an OverflowError straight away through an exception, rather than having an inf value silently injected into your calculations.

Note: This answer is a pure Gradle answer, I use this in IntelliJ on a regular basis but I don't know how the integration is with Android Studio. I am a believer in knowing what is going on for me, so this is how I use Gradle and Android.

TL;DR Full Example - https://github.com/ethankhall/driving-time-tracker/

Disclaimer: This is a project I am/was working on.

Gradle has a defined structure ( that you can change, link at the bottom tells you how ) that is very similar to Maven if you have ever used it.

Project Root
+-- src
|   +-- main (your project)
|   |   +-- java (where your java code goes)
|   |   +-- res  (where your res go)
|   |   +-- assets (where your assets go)
|   |   \-- AndroidManifest.xml
|   \-- instrumentTest (test project)
|       \-- java (where your java code goes)
+-- build.gradle
\-- settings.gradle

If you only have the one project, the settings.gradle file isn't needed. However you want to add more projects, so we need it.

Now let's take a peek at that build.gradle file. You are going to need this in it (to add the android tools)

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.3'
    }
}

Now we need to tell Gradle about some of the Android parts. It's pretty simple. A basic one (that works in most of my cases) looks like the following. I have a comment in this block, it will allow me to specify the version name and code when generating the APK.

build.gradle

apply plugin: "android"
android {
        compileSdkVersion 17
        /*
        defaultConfig {
            versionCode = 1
            versionName = "0.0.0"
        }
        */
    }

Something we are going to want to add, to help out anyone that hasn't seen the light of Gradle yet, a way for them to use the project without installing it.

build.gradle

task wrapper(type: org.gradle.api.tasks.wrapper.Wrapper) {
    gradleVersion = '1.4'
}

So now we have one project to build. Now we are going to add the others. I put them in a directory, maybe call it deps, or subProjects. It doesn't really matter, but you will need to know where you put it. To tell Gradle where the projects are you are going to need to add them to the settings.gradle.

Directory Structure:

Project Root
+-- src (see above)
+-- subProjects (where projects are held)
|   +-- reallyCoolProject1 (your first included project)
|       \-- See project structure for a normal app
|   \-- reallyCoolProject2 (your second included project)
|       \-- See project structure for a normal app
+-- build.gradle
\-- settings.gradle

settings.gradle:

include ':subProjects:reallyCoolProject1'
include ':subProjects:reallyCoolProject2'

The last thing you should make sure of is the subProjects/reallyCoolProject1/build.gradle has apply plugin: "android-library" instead of apply plugin: "android".

Like every Gradle project (and Maven) we now need to tell the root project about it's dependency. This can also include any normal Java dependencies that you want.

build.gradle

dependencies{
    compile 'com.fasterxml.jackson.core:jackson-core:2.1.4'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.1.4'
    compile project(":subProjects:reallyCoolProject1")
    compile project(':subProjects:reallyCoolProject2')
}

I know this seems like a lot of steps, but they are pretty easy once you do it once or twice. This way will also allow you to build on a CI server assuming you have the Android SDK installed there.

NDK Side Note: If you are going to use the NDK you are going to need something like below. Example build.gradle file can be found here: https://gist.github.com/khernyo/4226923

build.gradle

task copyNativeLibs(type: Copy) {
    from fileTree(dir: 'libs', include: '**/*.so' )  into  'build/native-libs'
}
tasks.withType(Compile) { compileTask -> compileTask.dependsOn copyNativeLibs }

clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
  pkgTask.jniDir new File('build/native-libs')
}

This is really annoying, and everyone in the JS community knows it. There should be this functionality:

const obj1 = {a:4, b:7};
const obj2 = Object.map(obj1, (k,v) => v + 5);

console.log(obj1); // {a:4, b:7}
console.log(obj2); // {a:9, b:12}

here is the naïve implementation:

Object.map = function(obj, fn, ctx){

    const ret = {};

    for(let k of Object.keys(obj)){
        ret[k] = fn.call(ctx || null, k, obj[k]);
    });

    return ret;
};

it is super annoying to have to implement this yourself all the time ;)

If you want something a little more sophisticated, that doesn't interfere with the Object class, try this:

let map = function (obj, fn, ctx) {
  return Object.keys(obj).reduce((a, b) => {
    a[b] = fn.call(ctx || null, b, obj[b]);
    return a;
  }, {});
};


const x = map({a: 2, b: 4}, (k,v) => {
    return v*2;
});

but it is safe to add this map function to Object, just don't add to Object.prototype.

Object.map = ... // fairly safe
Object.prototype.map ... // not ok

Maybe this helps:

a = [{ 'main_color': 'red', 'second_color':'blue'},
     { 'main_color': 'yellow', 'second_color':'green'},
     { 'main_color': 'yellow', 'second_color':'blue'}]

def in_dictlist((key, value), my_dictlist):
    for this in my_dictlist:
        if this[key] == value:
            return this
    return {}

print in_dictlist(('main_color','red'), a)
print in_dictlist(('main_color','pink'), a)

plt.errorbar can be used to plot x, y, error data (as opposed to the usual plt.plot)

import matplotlib.pyplot as plt
import numpy as np

x = np.array([1, 2, 3, 4, 5])
y = np.power(x, 2) # Effectively y = x**2
e = np.array([1.5, 2.6, 3.7, 4.6, 5.5])

plt.errorbar(x, y, e, linestyle='None', marker='^')

plt.show()

plt.errorbar accepts the same arguments as plt.plot with additional yerr and xerr which default to None (i.e. if you leave them blank it will act as plt.plot).

Prints pubkey and avoid the changed status by adding changed_when: False to cat task:

Using bootstrap with a little bit of customization, the following seems to work for me:

I need 3 partitions in my container and I tried this:

CSS:

.row.content {height: 100%; width:100%; position: fixed; }
.sidenav {
  padding-top: 20px;
  border: 1px solid #cecece;
  height: 100%;
}
.midnav {
  padding: 0px;
}

HTML:

  <div class="container-fluid text-center"> 
    <div class="row content">
    <div class="col-md-2 sidenav text-left">Some content 1</div>
    <div class="col-md-9 midnav text-left">Some content 2</div>
    <div class="col-md-1 sidenav text-center">Some content 3</div>
    </div>
  </div>

JavaScript's Date object supports the ISO date format, so as long as you have access to the date string, you can do something like this:

> foo = new Date("2012-07-14T01:00:00+01:00")
Sat, 14 Jul 2012 00:00:00 GMT
> foo.toTimeString()
'17:00:00 GMT-0700 (MST)'

If you want the time string without the seconds and the time zone then you can call the getHours() and getMinutes() methods on the Date object and format the time yourself.

Not sure what language you're using (you didn't specify), but you should be able to "escape" the quotation mark character with a backslash: "\"ROM\""

if you use the gmap V3 plugin: $("#map").gmap("removeAllMarkers");

see: http://www.smashinglabs.pl/gmap/documentation#after-load

To explain the two concepts by example, imagine you have an order entry system for a bookstore. The mapping of orders to items is many to many (n:m) because each order can have multiple items, and each item can be ordered by multiple orders. On the other hand, a lookup between customers and order is one to many (1:n) because a customer can place more than one order, but an order is never for more than one customer.

You can do this:

select t2.*
from t1
join t2 on t2.url = 'site.com/path/' + CAST(t1.id AS VARCHAR(10)) + '/more' 
where t1.id > 9000

Pay attention to CAST(t1.id AS VARCHAR(10)).

window.location is an object, not a string so you need to use window.location.href to get the actual string url

if (window.location.href.indexOf("?added-to-cart=555") >= 0) {
    alert("found it");
}

There is an operator just for this. For example, if I wanted to change a variable i by 3 then:

var someValue = 9;
var Increment  = 3;
for(var i=0;i<someValue;i+=Increment){
//do whatever
}

var someValue = 3;
var Increment  = 3;
for(var i=9;i>someValue;i+=Increment){
//do whatever
}

Try

List<SubProduct> subProducts = new List<SubProduct>(Model.subproduct);

or

List<SubProduct> subProducts = Model.subproducts as List<SubProduct>;

Assuming your table is called "Table1" and your column is called "Column1" then:

For i = 1 To ListObjects("Table1").ListRows.Count
    ListObjects("Table1").ListColumns("Column1").DataBodyRange(i) = "PHEV"
Next i

You should be able to use the variable name directly

ansible_ssh_host

Or you can go through hostvars without having to specify the host literally by using the magic variable inventory_hostname

hostvars[inventory_hostname].ansible_ssh_host

using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("Enter Your FirstName ");
            String FirstName = Console.ReadLine();

            Console.WriteLine("Enter Your LastName ");
            String LastName = Console.ReadLine();
            Console.ReadLine();

            Console.WriteLine("Hello {0}, {1} ", FirstName, LastName);
            Console.ReadLine();

        }
    }
}

The first answer is too complex, historic, and uninformative for my tastes.

It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,

• Free you from having to manually remove what you don't want, by forcing you to whitelist what you do want,
• Free resources that would otherwise be taken up because of Docker's implementation.

Let's start with the first. Very often with something like Debian you'll see.

RUN apt-get update \ 
  && apt-get dist-upgrade \
  && apt-get install <whatever> \
  && apt-get clean

We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,

RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;

It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree for an example of that).

By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean), and you would otherwise have lots of un-needed files in your final image.

Why do you need a cursor at all? Your entire segment of code can be replaced by this, which will run a lot faster on large numbers of rows.

UPDATE tarinvoice set confirmtocntctkey = PrimaryCntctKey 
FROM tarinvoice INNER JOIN tarcustomer ON tarinvoice.custkey = tarcustomer.custkey
WHERE confirmtocntctkey is null and tranno like '%115876'

This might not be relevant to your specific problem, but the error message you mentioned has many causes, one of them is using a return type for an [OperationContract] that is either abstract, interface, or not known to the WCF client code.

You want style image and Nav with float to each other then use like this

ol.widgets ul
{
list-style-image:url('some-img.gif');
}
ol.widgets ul li
{
float:left;
}

If you want the most recently added one, add a timestamp and select ordered in reverse order by highest timestamp, limit 1. If you want to go by ID, sort by ID. If you want to use the one you JUST added, use mysql_insert_id.

Using an outdated gradle version may also result to fail in synchronization. Download latest version from https://gradle.org/releases/ and download the "complete" latest version. Now replace it with the outdated version which is located C:\Program Files\Android\Android Studio\gradle. Go to settings(ctrl+alt+s) ,go to gradle and add the the new gradle directory in "use local gradle distribution" "Gradle home:C:\Program Files\Android\Android Studio\gradle\gradle4.4.1 ."

It Worked for me. Hope u understand.

So, rather return the whole object first, just wrap it to json_encode and then return it. This will return a proper and valid object.

public function id($id){
    $promotion = Promotion::find($id);
    return json_encode($promotion);
}

Or, For DB this will be just like,

public function id($id){
    $promotion = DB::table('promotions')->first();
    return json_encode($promotion);
}

I think it may help someone else.

My answer is not as asked but It is really simple to find if your system is little endian or big endian?

Code:

#include<stdio.h>

int main()
{
  int a = 1;
  char *b;

  b = (char *)&a;
  if (*b)
    printf("Little Endian\n");
  else
    printf("Big Endian\n");
}

• Percent encoding in the path section of a URL is expected to be decoded, but
• any + characters in the path component is expected to be treated literally.

To be explicit: + is only a special character in the query component.

Set in your .htaccess file

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L]
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

On CentOS Linux release 7.5.1804, we were able to make this work by editing /etc/selinux/config and changing the setting of SELINUX like so:

SELINUX=disabled

You mean this?

git checkout destination_branch
git merge tag_name

I wrote a helper for my razor project using some of the hints from other answers.

The ParseQueryString business is necessary because we are not allowed to tamper with the QueryString object of the current request.

@helper GetQueryStringWithValue(string key, string value) {
    var queryString = System.Web.HttpUtility.ParseQueryString(HttpContext.Current.Request.QueryString.ToString());
    queryString[key] = value;
    @Html.Raw(queryString.ToString())
}

I use it like this:

location.search = '[email protected]("var-name", "var-value")';

If you want it to take more than one value, just change the parameters to a Dictionary and add the pairs to the query string.

As @ J_F answered in the comments, using {r echo = T, results = 'hide'}.

I wanted to expand on their answer - there are great resources you can access to determine all possible options for your chunk and output display - I keep a printed copy at my desk!

You can find them either on the RStudio Website under Cheatsheets (look for the R Markdown cheatsheet and R Markdown Reference Guide) or, in RStudio, navigate to the "Help" tab, choose "Cheatsheets", and look for the same documents there.

Finally to set default chunk options, you can run (in your first chunk) something like the following code if you want most chunks to have the same behavior:

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = T,
                      results = "hide")
```

Later, you can modify the behavior of individual chunks like this, which will replace the default value for just the results option.

```{r analysis, results="markup"}
# code here
```

Here is a simple mail sending code with attachment

try  
{  
    SmtpClient mailServer = new SmtpClient("smtp.gmail.com", 587);  
    mailServer.EnableSsl = true;  

    mailServer.Credentials = new System.Net.NetworkCredential("[email protected]", "mypassword");  

    string from = "[email protected]";  
    string to = "[email protected]";  
    MailMessage msg = new MailMessage(from, to);  
    msg.Subject = "Enter the subject here";  
    msg.Body = "The message goes here.";
    msg.Attachments.Add(new Attachment("D:\\myfile.txt"));
    mailServer.Send(msg);  
}  
catch (Exception ex)  
{  
    Console.WriteLine("Unable to send email. Error : " + ex);  
}

The code is very long so I can't paste all the code.

There could be any number of reasons why your code doesn't work. Maybe you declared the button variables twice so you aren't actually changing enabling/disabling the button like you think you are. Maybe you are blocking the EDT.

You need to create a SSCCE to post on the forum.

So its up to you to isolate the problem. Start with a simple frame thas two buttons and see if your code works. Once you get that working, then try starting a Thread that simply sleeps for 10 seconds to see if it still works.

If $_SERVER['HTTP_REFERER'] variable doesn't seems to work, then you can either use Google Analytics or AddThis Analytics.

Kotlin's @Transientannotation also does the trick apparently.

data class Json(
    @field:SerializedName("serialized_field_1") val field1: String,
    @field:SerializedName("serialized_field_2") val field2: String,
    @Transient val field3: String
)

Output:

{"serialized_field_1":"VALUE1","serialized_field_2":"VALUE2"}
