When you're running npm install in the project's root, it installs all of the npm dependencies into the project's node_modules directory.

If you take a look at the project's node_modules directory, you should see a directory called http-server, which holds the http-server package, and a .bin folder, which holds the executable binaries from the installed dependencies. The .bin directory should have the http-server binary (or a link to it).

So in your case, you should be able to start the http-server by running the following from your project's root directory (instead of npm start):

./node_modules/.bin/http-server -a localhost -p 8000 -c-1

This should have the same effect as running npm start.

If you're running a Bash shell, you can simplify this by adding the ./node_modules/.bin folder to your $PATH environment variable:

export PATH=./node_modules/.bin:$PATH

This will put this folder on your path, and you should be able to simply run

http-server -a localhost -p 8000 -c-1

On CentOS (my version is 6.5) when editing crontab you must close the editor to reflect your changes in CRON.

crontab -e

After that command You can see that new entry appears in /var/log/cron

Sep 24 10:44:26 ***** crontab[17216]: (*****) BEGIN EDIT (*****)

But only saving crontab editor after making some changes does not work. You must leave the editor to reflect changes in cron. After exiting new entry appears in the log:

Sep 24 10:47:58 ***** crontab[17216]: (*****) END EDIT (*****)

From this point changes you made are visible to CRON.

It means you're calling http from https. You can use src="//url.to/script.js" in your script tag and it will auto-detect.

Alternately you can use use https in your src even if you will be publishing it to a http page. This will avoid the potential issue mentioned in the comments.

In case anyone doesn't get results from the other answers, I fixed a similar problem by:

1. adding --hidden-import flags as needed for any missing modules

2. cleaning up the associated folders and spec files:

rmdir /s /q dist

rmdir /s /q build

del /s /q my_service.spec

3. Running the commands for installation as Administrator

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

I think this should be:

$('.home').click(function() {
     $(this).css('background', 'url(images/tabs3.png)');
 });

and remove this:

<div class="home" onclick="function()">
     //-----------^^^^^^^^^^^^^^^^^^^^---------no need for this

You have to make sure you have a correct path to your image.

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

In a recent project, I had to update the Kendo UI Grid based on some calls, that were happening on some dropdown selects. Here is what I ended up using:

$.ajax({
        url: '/api/....',
        data: { myIDSArray: javascriptArrayOfIDs },
        traditional: true,
        success: function(result) {
            searchResults = result;
        }
    }).done(function() {
        var dataSource = new kendo.data.DataSource({ data: searchResults });
        var grid = $('#myKendoGrid').data("kendoGrid");
        dataSource.read();
        grid.setDataSource(dataSource);
    });

Hopefully this will save you some time.

var output = 5 + '' + 6;

Here is a solution for reading - not writing - the extended properties based on what I found on this page and at help with shell32 objects.

To be clear this is a hack. It looks like this code will still run on Windows 10 but will hit on some empty properties. Previous version of Windows should use:

        var i = 0;
        while (true)
        {
            ...
            if (String.IsNullOrEmpty(header)) break;
            ...
            i++;

On Windows 10 we assume that there are about 320 properties to read and simply skip the empty entries:

    private Dictionary<string, string> GetExtendedProperties(string filePath)
    {
        var directory = Path.GetDirectoryName(filePath);
        var shell = new Shell32.Shell();
        var shellFolder = shell.NameSpace(directory);
        var fileName = Path.GetFileName(filePath);
        var folderitem = shellFolder.ParseName(fileName);
        var dictionary = new Dictionary<string, string>();
        var i = -1;
        while (++i < 320)
        {
            var header = shellFolder.GetDetailsOf(null, i);
            if (String.IsNullOrEmpty(header)) continue;
            var value = shellFolder.GetDetailsOf(folderitem, i);
            if (!dictionary.ContainsKey(header)) dictionary.Add(header, value);
            Console.WriteLine(header +": " + value);
        }
        Marshal.ReleaseComObject(shell);
        Marshal.ReleaseComObject(shellFolder);
        return dictionary;
    }

As mentioned you need to reference the Com assembly Interop.Shell32.

If you get an STA related exception, you will find the solution here:

Exception when using Shell32 to get File extended properties

I have no idea what those properties names would be like on a foreign system and couldn't find information about which localizable constants to use in order to access the dictionary. I also found that not all the properties from the Properties dialog were present in the dictionary returned.

BTW this is terribly slow and - at least on Windows 10 - parsing dates in the string retrieved would be a challenge so using this seems to be a bad idea to start with.

On Windows 10 you should definitely use the Windows.Storage library which contains the SystemPhotoProperties, SystemMusicProperties etc. https://docs.microsoft.com/en-us/windows/uwp/files/quickstart-getting-file-properties

And finally, I posted a much better solution that uses WindowsAPICodePack there

Compare Side-By-Side looks like the most convenient to me though it's not the most popular:

UPD: I need to add that this plugin can freeze ST while comparing big files. It is certainly not the best decision if you are going to compare large texts.

You can refer to https://curl.haxx.se/docs/http-cookies.html for a complete tutorial of how to work with cookies. You can use

curl -c /path/to/cookiefile http://yourhost/

to write to a cookie file and start engine and to use cookie you can use

curl -b /path/to/cookiefile  http://yourhost/

to read cookies from and start the cookie engine, or if it isn't a file it will pass on the given string.

just use .title(), and it will convert first letter of every word in capital, rest in small:

>>> a='mohs shahid ss'
>>> a.title()
'Mohs Shahid Ss'
>>> a='TRUE'
>>> b=a.title()
>>> b
'True'
>>> eval(b)
True

It's probably caused by a local network connectivity issue (but also a DNS error is possible). Unfortunately HResult is generic, however you can determine the exact issue catching HttpRequestException and then inspecting InnerException: if it's a WebException then you can check the WebException.Status property, for example WebExceptionStatus.NameResolutionFailure should indicate a DNS resolution problem.

It may happen, there isn't much you can do.

What I'd suggest to always wrap that (network related) code in a loop with a try/catch block (as also suggested here for other fallible operations). Handle known exceptions, wait a little (say 1000 msec) and try again (for say 3 times). Only if failed all times then you can quit/report an error to your users. Very raw example like this:

private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;

public static async Task<HttpResponseMessage> GetFromUrlAsync(string url) {
    using (var client = new HttpClient()) {
        for (int i=1; i <= NumberOfRetries; ++i) {
            try {
                return await client.GetAsync(url); 
            }
            catch (Exception e) when (i < NumberOfRetries) {
                await Task.Delay(DelayOnRetry);
            }
        }
    }
}

XPath 1.0 doesn't handle regex natively, you could try something like

//*[starts-with(@id, 'sometext') and ends-with(@id, '_text')]

(as pointed out by paul t, //*[boolean(number(substring-before(substring-after(@id, "sometext"), "_text")))] could be used to perform the same check your original regex does, if you need to check for middle digits as well)

In XPath 2.0, try

//*[matches(@id, 'sometext\d+_text')]

Execute the workbench.action.reloadWindow command.

There are some ways to do so:

1. Open the command palette (Ctrl + Shift + P) and execute the command:

   >Reload Window    
   

2. Define a keybinding for the command (for example CTRL+F5) in keybindings.json:

   [
     {
       "key": "ctrl+f5",
       "command": "workbench.action.reloadWindow",
       "when": "editorTextFocus"
     }
   ]
   

There is a discussion on GitHub because of a question similar to this one: https://gist.github.com/1398757

You can use other projects for guidance, search in GitHub for:

• ThreeNodes.js - in my opinion, seems to have a specific structure not suitable for every project;
• lighter - an more simple structure, but lacks a bit of organization;

And finally, in a book (http://shop.oreilly.com/product/0636920025344.do) suggests this structure:

+-- index.html
+-- js/
¦   +-- main.js
¦   +-- models/
¦   +-- views/
¦   +-- collections/
¦   +-- templates/
¦   +-- libs/
¦       +-- backbone/
¦       +-- underscore/
¦       +-- ...
+-- css/
+-- ...

The problem is that you define it inside the class, which

a) means the second argument is implicit (this) and

b) it will not do what you want it do, namely extend std::ostream.

You have to define it as a free function:

class A { /* ... */ };
std::ostream& operator<<(std::ostream&, const A& a);

Call the ToList() in the foreach loop. This way we dont need a temp variable copy. It depends on Linq which is available since .Net 3.5.

using System.Linq;

foreach(string key in colStates.Keys.ToList())
{
  double  Percent = colStates[key] / TotalCount;

    if (Percent < 0.05)
    {
        OtherCount += colStates[key];
        colStates[key] = 0;
    }
}

In the source header you can declare:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
....

It is described in the PEP 0263:

Then you can use UTF-8 in strings:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

u = 'idzie waz waska drózka'
uu = u.decode('utf8')
s = uu.encode('cp1250')
print(s)

This declaration is not needed in Python 3 as UTF-8 is the default source encoding (see PEP 3120).

In addition, it may be worth verifying that your text editor properly encodes your code in UTF-8. Otherwise, you may have invisible characters that are not interpreted as UTF-8.

If you don't need typesafe, just bring block to a new separated file and change the extension to .js,.jsx

You could follow maven's standard project layout. You don't have to actually use maven, but it would make the transition easier in the future (if necessary). Plus, other developers will be used to seeing that layout, since many open source projects are layed out this way,

lucky i find a solution. you can

import { ChangeEvent } from 'react';

and then write code like: e:ChangeEvent<HTMLInputElement>

Git tags are just pointers to the commit. So you use them the same way as you do HEAD, branch names or commit sha hashes. You can use tags with any git command that accepts commit/revision arguments. You can try it with git rev-parse tagname to display the commit it points to.

In your case you have at least these two alternatives:

1. Reset the current branch to specific tag:

   git reset --hard tagname
   

2. Generate revert commit on top to get you to the state of the tag:

   git revert tag
   

This might introduce some conflicts if you have merge commits though.

@bogatron has it right, you can use where, it's worth noting that you can do this natively in pandas:

df1 = df.where(pd.notnull(df), None)

Note: this changes the dtype of all columns to object.

Example:

In [1]: df = pd.DataFrame([1, np.nan])

In [2]: df
Out[2]: 
    0
0   1
1 NaN

In [3]: df1 = df.where(pd.notnull(df), None)

In [4]: df1
Out[4]: 
      0
0     1
1  None

Note: what you cannot do recast the DataFrames dtype to allow all datatypes types, using astype, and then the DataFrame fillna method:

df1 = df.astype(object).replace(np.nan, 'None')

Unfortunately neither this, nor using replace, works with None see this (closed) issue.

As an aside, it's worth noting that for most use cases you don't need to replace NaN with None, see this question about the difference between NaN and None in pandas.

However, in this specific case it seems you do (at least at the time of this answer).

It is important to recognize that the copyright laws have changed and that for non-US sources, especially after the USA joining the Berne Convention on March 1, 1989, copyright registration in not necessary for enforcement of a copyright notice.
Here is a resumé quoted from the Cornell University Law School (copied on March 4, 2015 from https://www.law.cornell.edu/wex/copyright:

"Copyright copyright: an overview

The U.S. Copyright Act, 17 U.S.C. §§ 101 - 810, is Federal legislation enacted by Congress under its Constitutional grant of authority to protect the writings of authors. See U.S. Constitution, Article I, Section 8. Changing technology has led to an ever expanding understanding of the word "writings." The Copyright Act now reaches architectural design, software, the graphic arts, motion pictures, and sound recordings. See § 106. As of January 1, 1978, all works of authorship fixed in a tangible medium of expression and within the subject matter of copyright were deemed to fall within the exclusive jurisdiction of the Copyright Act regardless of whether the work was created before or after that date and whether published or unpublished. See § 301. See also preemption.

The owner of a copyright has the exclusive right to reproduce, distribute, perform, display, license, and to prepare derivative works based on the copyrighted work. See § 106. The exclusive rights of the copyright owner are subject to limitation by the doctrine of "fair use." See § 107. Fair use of a copyrighted work for purposes such as criticism, comment, news reporting, teaching, scholarship, or research is not copyright infringement. To determine whether or not a particular use qualifies as fair use, courts apply a multi-factor balancing test. See § 107.

Copyright protection subsists in original works of authorship fixed in any tangible medium of expression from which they can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device. See § 102. Copyright protection does not extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery. For example, if a book is written describing a new system of bookkeeping, copyright protection only extends to the author's description of the bookkeeping system; it does not protect the system itself. See Baker v. Selden, 101 U.S. 99 (1879).

According to the Copyright Act of 1976, registration of copyright is voluntary and may take place at any time during the term of protection. See § 408. Although registration of a work with the Copyright Office is not a precondition for protection, an action for copyright infringement may not be commenced until the copyright has been formally registered with the Copyright Office. See § 411.

Deposit of copies with the Copyright Office for use by the Library of Congress is a separate requirement from registration. Failure to comply with the deposit requirement within three months of publication of the protected work may result in a civil fine. See § 407. The Register of Copyrights may exempt certain categories of material from the deposit requirement.

In 1989 the U.S. joined the Berne Convention for the Protection of Literary and Artistic Works. In accordance with the requirements of the Berne Convention, notice is no longer a condition of protection for works published after March 1, 1989. This change to the notice requirement applies only prospectively to copies of works publicly distributed after March 1, 1989.

The Berne Convention also modified the rule making copyright registration a precondition to commencing a lawsuit for infringement. For works originating from a Berne Convention country, an infringement action may be initiated without registering the work with the U.S. Copyright Office. However, for works of U.S. origin, registration prior to filing suit is still required.

The federal agency charged with administering the act is the Copyright Office of the Library of Congress. See § 701 of the act. Its regulations are found in Parts 201 - 204 of title 37 of the Code of Federal Regulations."

I find it easier to implement it in the XML file as it can be harder to trace the line of code in a class with hundreds of lines. For the XML you can use "null":

android:divider="@null"

The quick and dirty way is using json_encode and json_decode which will turn the entire array (including sub elements) into an object.

$clasa = json_decode(json_encode($clasa)); //Turn it into an object

The same can be used to convert an object into an array. Simply add , true to json_decode to return an associated array:

$clasa = json_decode(json_encode($clasa), true); //Turn it into an array

An alternate way (without being dirty) is simply a recursive function:

function convertToObject($array) {
    $object = new stdClass();
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            $value = convertToObject($value);
        }
        $object->$key = $value;
    }
    return $object;
}

or in full code:

<?php
    function convertToObject($array) {
        $object = new stdClass();
        foreach ($array as $key => $value) {
            if (is_array($value)) {
                $value = convertToObject($value);
            }
            $object->$key = $value;
        }
        return $object;
    }

    $clasa = array(
            'e1' => array('nume' => 'Nitu', 'prenume' => 'Andrei', 'sex' => 'm', 'varsta' => 23),
            'e2' => array('nume' => 'Nae', 'prenume' => 'Ionel', 'sex' => 'm', 'varsta' => 27),
            'e3' => array('nume' => 'Noman', 'prenume' => 'Alice', 'sex' => 'f', 'varsta' => 22),
            'e4' => array('nume' => 'Geangos', 'prenume' => 'Bogdan', 'sex' => 'm', 'varsta' => 23),
            'e5' => array('nume' => 'Vasile', 'prenume' => 'Mihai', 'sex' => 'm', 'varsta' => 25)
    );

    $obj = convertToObject($clasa);
    print_r($obj);
?>

which outputs (note that there's no arrays - only stdClass's):

stdClass Object
(
    [e1] => stdClass Object
        (
            [nume] => Nitu
            [prenume] => Andrei
            [sex] => m
            [varsta] => 23
        )

    [e2] => stdClass Object
        (
            [nume] => Nae
            [prenume] => Ionel
            [sex] => m
            [varsta] => 27
        )

    [e3] => stdClass Object
        (
            [nume] => Noman
            [prenume] => Alice
            [sex] => f
            [varsta] => 22
        )

    [e4] => stdClass Object
        (
            [nume] => Geangos
            [prenume] => Bogdan
            [sex] => m
            [varsta] => 23
        )

    [e5] => stdClass Object
        (
            [nume] => Vasile
            [prenume] => Mihai
            [sex] => m
            [varsta] => 25
        )

)

So you'd refer to it by $obj->e5->nume.

DEMO

For sending mails using php mail function is used. But mail function requires SMTP server for sending emails. we need to mention SMTP host and SMTP port in php.ini file. Upon successful configuration of SMTP server mails will be sent successfully sent through php scripts.

Solution to this is three steps:

1. Within MySQL my.ini/ my.cnf file change the bind-address to accept connection from all hosts (0.0.0.0).

2. Within aws console - ec2 - specific security group open your mysql port (default is 3306) to accept connections from all hosts (0.0.0.0).

3. Within windows firewall add the mysql port (default is 3306) to exceptions.

And this will start accepting remote connections.

public static LocalDate firstDayOfPreviousMonth(LocalDate date) {
        return date.minusMonths(1).withDayOfMonth(1);

You should use UNION if you want to combine different resultsets. Try the following:

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id  
        WHERE products_id = 181) AS A)
UNION 

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id 
        WHERE products_id = 180) AS B
ON A.orders_id=B.orders_id)

1. rebuild project in VS
2. copy project folder to iis folder, probably C:\inetpub\wwwroot\
3. in iis manager (run>inetmgr) add website, point to folder, point application pool based on your .net
4. add web service to created website, almost the same as 3.
5. INSTALL ASP for windows 7 and .net 4.0: c:\windows\microsoft.net framework\v4.(some numbers)\regiis.exe -i
6. check access to web service on your browser

Grokking lookaround rapidly.
How to distinguish lookahead and lookbehind? Take 2 minutes tour with me:

(?=) - positive lookahead
(?<=) - positive lookbehind

Suppose

    A  B  C #in a line

Now, we ask B, Where are you?
B has two solutions to declare it location:

One, B has A ahead and has C bebind
Two, B is ahead(lookahead) of C and behind (lookhehind) A.

As we can see, the behind and ahead are opposite in the two solutions.
Regex is solution Two.

If we are talking about FLYME OS (Meizu) ONLY there are it's own Security app with permissions.

To open it use following intent:

Of-cause BuildConfig is your app's BuildConfig.

If you want to launch VM by sending arguments, you should send VM arguments and not Program arguments.

Program arguments are arguments that are passed to your application, which are accessible via the "args" String array parameter of your main method. VM arguments are arguments such as System properties that are passed to the JavaSW interpreter. The Debug configuration above is essentially equivalent to:

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3

The VM arguments go after the call to your Java interpreter (ie, 'java') and before the Java class. Program arguments go after your Java class.

Consider a program ArgsTest.java:

package test;

import java.io.IOException;

    public class ArgsTest {

        public static void main(String[] args) throws IOException {

            System.out.println("Program Arguments:");
            for (String arg : args) {
                System.out.println("\t" + arg);
            }

            System.out.println("System Properties from VM Arguments");
            String sysProp1 = "sysProp1";
            System.out.println("\tName:" + sysProp1 + ", Value:" + System.getProperty(sysProp1));
            String sysProp2 = "sysProp2";
            System.out.println("\tName:" + sysProp2 + ", Value:" + System.getProperty(sysProp2));

        }
    }

If given input as,

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3 

in the commandline, in project bin folder would give the following result:

Program Arguments:
  pro1
  pro2
  pro3
System Properties from VM Arguments
  Name:sysProp1, Value:sp1
  Name:sysProp2, Value:sp2

If the two hex strings are the same length and you want a hex string output then you might try this.

def hexxor(a, b):    # xor two hex strings of the same length
    return "".join(["%x" % (int(x,16) ^ int(y,16)) for (x, y) in zip(a, b)])

you need to reconfigure your tnsnames.ora so that it can point to your hostname after that listener will be able to pick the new hostname. after which check the status of your listener lsnrctl status and start listener lsnrctl start then register your listener. Alter system register

One thing to note, if you have a log4j.properties file on your classpath you do not need to call BasicConfigurator. A description of how to configure the properties file is here.

You could pinpoint whether your IDE is causing the issue by trying to run this class from the command line with log4j.jar and log4j.properties on your classpath.

Try using JMyron How To Use Webcam Using Java. I think using JMyron is the easiest way to access a webcam using java. I tried to use it with a 64-bit processor, but it gave me an error. It worked just fine on a 32-bit processor, though.

Because textContent is not supported in IE8 and older, here is a workaround:

var node = document.getElementById('test'),
var text  = node.textContent || node.innerText;
alert(text);

innerText does work in IE.

$business_day_ct = 0;

$max_days = 10000 + $num_days;  // to avoid any possibility of an infinite loop

I know some things have changed in AC 2010. However, the old-fashioned ADODB is, as far as I know, the best way to go in VBA. An Example:

Dim cn As ADODB.Connection
Dim cmd As ADODB.Command
Dim prm As ADODB.Parameter
Dim rs As ADODB.Recordset
Dim colReturn As New Collection

Dim SQL As String
SQL = _
    "SELECT c.ClientID, c.LastName, c.FirstName, c.MI, c.DOB, c.SSN, " & _
    "c.RaceID, c.EthnicityID, c.GenderID, c.Deleted, c.RecordDate " & _
    "FROM tblClient AS c " & _
    "WHERE c.ClientID = @ClientID"

Set cn = New ADODB.Connection
Set cmd = New ADODB.Command

With cn
    .Provider = DataConnection.MyADOProvider
    .ConnectionString = DataConnection.MyADOConnectionString
    .Open
End With

With cmd
    .CommandText = SQL
    .ActiveConnection = cn
    Set prm = .CreateParameter("@ClientID", adInteger, adParamInput, , mlngClientID)
    .Parameters.Append prm
End With

Set rs = cmd.Execute

With rs
    If Not .EOF Then
        Do Until .EOF
            mstrLastName = Nz(!LastName, "")
            mstrFirstName = Nz(!FirstName, "")
            mstrMI = Nz(!MI, "")
            mdDOB = !DOB
            mstrSSN = Nz(!SSN, "")
            mlngRaceID = Nz(!RaceID, -1)
            mlngEthnicityID = Nz(!EthnicityID, -1)
            mlngGenderID = Nz(!GenderID, -1)
            mbooDeleted = Deleted
            mdRecordDate = Nz(!RecordDate, "")

            .MoveNext
        Loop
    End If
    .Close
End With

cn.Close

Set rs = Nothing
Set cn = Nothing

When using NOT IN, you should also consider NOT EXISTS, which handles the null cases silently. See also PostgreSQL Wiki

SELECT mac, creation_date 
FROM logs lo
WHERE logs_type_id=11
AND NOT EXISTS (
  SELECT *
  FROM consols nx
  WHERE nx.mac = lo.mac
  );

Stub is a function definition that has correct function name, the correct number of parameters and produces dummy result of the correct type.

It helps to write the test and serves as a kind of scaffolding to make it possible to run the examples even before the function design is complete

For SVG elements

Using something like selection.node().getBBox() you get values like

{
    height: 5, 
    width: 5, 
    y: 50, 
    x: 20
} 

For HTML elements

Use selection.node().getBoundingClientRect()

I know this is an OLD Question and there are multiple answers. How ever according to the docs and my experience on laravel below is the good "Eloquent way" of handling things

In your model, add a mutator/Getter like this

public function getCreatedAtTimeAttribute()
{
   return $this->created_at->toDateString();
}

Another way is to cast the columns in your model, populate the $cast array

$casts = [
   'created_at' => 'string'
]

The catch here is that you won't be able to use the Carbon on this model again since Eloquent will always cast the column into string

Hope it helps :)

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework.

REST

RESTs sweet spot is when you are exposing a public API over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP

SOAP brings it’s own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each implement some business logic through different interfaces.

Though SOAP is commonly referred to as “web services” this is a misnomer. SOAP has very little if anything to do with the Web. REST provides true “Web services” based on URIs and HTTP.

Reference: http://spf13.com/post/soap-vs-rest

And finally: What they could be referring to is REST vs. RPC See this: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/

This was not what I was expecting as a solution (though it is a legitimate use case). My requirement was to allow an existing buggy client (a mobile app which already released) to use alternate names.

The solution lies in providing a separate setter method like this:

@JsonSetter( "r" )
public void alternateSetRed( byte red ) {
    this.red = red;
}

Use brackets:

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND 
    (date='$Date_Today' 
     OR date='$Date_Yesterday' 
     OR date='$Date_TwoDaysAgo' 
     OR date='$Date_ThreeDaysAgo' 
     OR date='$Date_FourDaysAgo' 
     OR date='$Date_FiveDaysAgo' 
     OR date='$Date_SixDaysAgo' 
     OR date='$Date_SevenDaysAgo'
    )
");

But you should alsos have a look at the IN operator. So you can say ´date IN ('$date1','$date2',...)`

But if you have always a set of consecutive days why don't you do the following for the date part

date <= $Date_Today AND date >= $Date_SevenDaysAgo

You can't, you can NEVER restore from a higher version to a lower version of SQL Server. Your only option is to script out the database and then transfer the data via SSIS, BCP, linked server or scripting out the data

It would be something like:

document.getElementById("username").value="Username";
document.forms[0].submit()

Or similar edit: you guys are too fast ;)

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

Answers above, including the GitHub one, had some issues for my scenario and also back button or direct url change from browser was reloading the controller, which I did not like. I finally went with the following approach:

1. Define a property in route definitions, called 'noReload' for those routes where you don't want the controller to reload on route change.

.when('/:param1/:param2?/:param3?', {
    templateUrl: 'home.html',
    controller: 'HomeController',
    controllerAs: 'vm',
    noReload: true
})

2. In the run function of your module, put the logic that checks for those routes. It will prevent reload only if noReload is true and previous route controller is the same.

fooRun.$inject = ['$rootScope', '$route', '$routeParams'];

function fooRun($rootScope, $route, $routeParams) {
    $rootScope.$on('$routeChangeStart', function (event, nextRoute, lastRoute) {
        if (lastRoute && nextRoute.noReload 
         && lastRoute.controller === nextRoute.controller) {
            var un = $rootScope.$on('$locationChangeSuccess', function () {
                un();
                // Broadcast routeUpdate if params changed. Also update
                // $routeParams accordingly
                if (!angular.equals($route.current.params, lastRoute.params)) {
                    lastRoute.params = nextRoute.params;
                    angular.copy(lastRoute.params, $routeParams);
                    $rootScope.$broadcast('$routeUpdate', lastRoute);
                }
                // Prevent reload of controller by setting current
                // route to the previous one.
                $route.current = lastRoute;
            });
        }
    });
}

3. Finally, in the controller, listen to $routeUpdate event so you can do whatever you need to do when route parameters change.

HomeController.$inject = ['$scope', '$routeParams'];

function HomeController($scope, $routeParams) {
    //(...)

    $scope.$on("$routeUpdate", function handler(route) {
        // Do whatever you need to do with new $routeParams
        // You can also access the route from the parameter passed
        // to the event
    });

    //(...)
}

Keep in mind that with this approach, you don't change things in the controller and then update the path accordingly. It's the other way around. You first change the path, then listen to $routeUpdate event to change things in the controller when route parameters change.

This keeps things simple and consistent as you can use the same logic both when you simply change path (but without expensive $http requests if you like) and when you completely reload the browser.

use curl php library: http://php.net/manual/en/book.curl.php

direct example: CURL_EXEC:

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

This is the only thing that worked for me:

import React, { Component } from 'react';

AppDomain.UnhandledException Event

This event provides notification of uncaught exceptions. It allows the application to log information about the exception before the system default handler reports the exception to the user and terminates the application.

   public App()
   {
      AppDomain currentDomain = AppDomain.CurrentDomain;
      currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);    
   }

   static void MyHandler(object sender, UnhandledExceptionEventArgs args) 
   {
      Exception e = (Exception) args.ExceptionObject;
      Console.WriteLine("MyHandler caught : " + e.Message);
      Console.WriteLine("Runtime terminating: {0}", args.IsTerminating);
   }

If the UnhandledException event is handled in the default application domain, it is raised there for any unhandled exception in any thread, no matter what application domain the thread started in. If the thread started in an application domain that has an event handler for UnhandledException, the event is raised in that application domain. If that application domain is not the default application domain, and there is also an event handler in the default application domain, the event is raised in both application domains.

For example, suppose a thread starts in application domain "AD1", calls a method in application domain "AD2", and from there calls a method in application domain "AD3", where it throws an exception. The first application domain in which the UnhandledException event can be raised is "AD1". If that application domain is not the default application domain, the event can also be raised in the default application domain.

Before changing stored procedure please check what is the output of your current one. In SQL Server Management run following:

DECLARE @NewId int
EXEC    @return_value = [dbo].[usp_InsertContract]
            N'Gary',
            @NewId OUTPUT
SELECT  @NewId

See what it returns. This may give you some hints of why your out param is not filled.

You can't use Microsoft.Office.Interop.Excel without having ms office installed.

Just search in google for some libraries, which allows to modify xls or xlsx:

• http://code.google.com/p/excellibrary/
• http://simpleooxml.codeplex.com/ (only xlsx)

for those who are having trouble with similar problems in Numpy, a very simple solution would be:

defining dtype=object when defining an array for assigning values to it. for instance:

out = np.empty_like(lil_img, dtype=object)

You can try

int sum = list.stream().filter(o->o.field>10).mapToInt(o->o.field).sum();

Like explained here

You can use git cherry-pick for this. 'cherry-pick' will apply a commit onto the branch your on now.

then do

git rebase --hard <SHA1 of A>

then apply the D and E commits.

git cherry-pick <SHA1 of D>
git cherry-pick <SHA1 of E>

This will skip out the B and C commit. Having said that it might be impossible to apply the D commit to the branch without B, so YMMV.

Commands listed for use in normal mode (prefix with : for command mode).
Tested in Vim.

By line amount:

• numdd - will delete num lines DOWN starting count from current cursor position (e.g. 5dd will delete current line and 4 lines under it => deletes current line and (num-1) lines under it)
• numdk - will delete num lines UP from current line and current line itself (e.g. 3dk will delete current line and 3 lines above it => deletes current line and num lines above it)

By line numbers:

• dnumG - will delete lines from current line (inclusive) UP to line number num (inclusive) (e.g. if cursor is currently on line 5 d2G will delete lines 2-5 inclusive)
• dnumgg - will delete lines from current line (inclusive) DOWN to the line number num (inclusive) (e.g. if cursor is currently on line 2 d6gg will delete lines 2-6 inclusive)
• (command mode only) :num1,num2d - will delete lines line number num1 (inclusive) DOWN to the line number num2 (inclusive). Note: if num1 is greater than num2 — vim will react with Backwards range given, OK to swap (y/n)?

Implementation wise you will often see inside super() statement in subclasses constructors, something like:

public class A extends AbstractB{

  public A(...){
     super(String constructorArgForB, ...);
     ...
  }
}

Maybe I'm misunderstanding your question, but the offset is supposed to give you two variables: a horizontal and a vertical. This defines the position of the element. So what you're looking for is:

$("#whatever").offset().left

and

$("#whatever").offset().top

If you need to know where the right boundary of your element is, then you should use:

$("#whatever").offset().left + $("#whatever").outerWidth()

For anyone trying to set this for Rails projects, add

set directory=tmp,/tmp

into your

~/.vimrc

So the .swp files will be in their natural location - the tmp directory (per project).

Using annotations, you can do something like this:

import org.junit.*;
import static org.junit.Assert.*;
import java.util.*;

class SomethingUnitTest {
    @BeforeClass
    public static void runBeforeClass()
    {

    }

    @AfterClass
    public static void runAfterClass()
    {  

    }

    @Before  
    public void setUp()
    {

    }

    @After
    public void tearDown()
    {

    }

    @Test
    public void testSomethingOrOther()
    {

    }

}

I haven't actually tried this, but this answer from the web sounds promising:

Wireshark can't actually capture local packets on windows XP due to the nature of the windows TCP stack. When packets are sent and received on the same machine they don't seem to cross the network boundary that wireshark monitors.

However there is a way around this, you can route the local traffic out via your network gateway (router) by setting up a (temporary) static route on your windows XP machine.

Say your XP IP address is 192.168.0.2 and your gateway (router) address is 192.168.0.1 you could run the following command from windows XP command line to force all local traffic out and back across the network boundary, so wireshark could then track the data (note that wireshark will report packets twice in this scenario, once when they leave your pc and once when they return).

route add 192.168.0.2 mask 255.255.255.255 192.168.0.1 metric 1

In Objective-C, a @synchronized block handles locking and unlocking (as well as possible exceptions) automatically for you. The runtime dynamically essentially generates an NSRecursiveLock that is associated with the object you're synchronizing on. This Apple documentation explains it in more detail. This is why you're not seeing the log messages from your NSLock subclass — the object you synchronize on can be anything, not just an NSLock.

Basically, @synchronized (...) is a convenience construct that streamlines your code. Like most simplifying abstractions, it has associated overhead (think of it as a hidden cost), and it's good to be aware of that, but raw performance is probably not the supreme goal when using such constructs anyway.

In my case even after following all of the above. I had to upgrade my project from .net 3.5 to .net 4 to authorize against our internal exchange 2010 mail server.

you can loop through the data frame like this .

I have been working on a Java servlet application that needs to construct very dynamic SQL statements for adhoc reporting purposes. The basic function of the app is to feed a bunch of named HTTP request parameters into a pre-coded query, and generate a nicely formatted table of output. I used Spring MVC and the dependency injection framework to store all of my SQL queries in XML files and load them into the reporting application, along with the table formatting information. Eventually, the reporting requirements became more complicated than the capabilities of the existing parameter mapping frameworks and I had to write my own. It was an interesting exercise in development and produced a framework for parameter mapping much more robust than anything else I could find.

The new parameter mappings looked as such:

select app.name as "App", 
       ${optional(" app.owner as "Owner", "):showOwner}
       sv.name as "Server", sum(act.trans_ct) as "Trans"
  from activity_records act, servers sv, applications app
 where act.server_id = sv.id
   and act.app_id = app.id
   and sv.id = ${integer(0,50):serverId}
   and app.id in ${integerList(50):appId}
 group by app.name, ${optional(" app.owner, "):showOwner} sv.name
 order by app.name, sv.name

The beauty of the resulting framework was that it could process HTTP request parameters directly into the query with proper type checking and limit checking. No extra mappings required for input validation. In the example query above, the parameter named serverId would be checked to make sure it could cast to an integer and was in the range of 0-50. The parameter appId would be processed as an array of integers, with a length limit of 50. If the field showOwner is present and set to "true", the bits of SQL in the quotes will be added to the generated query for the optional field mappings. field Several more parameter type mappings are available including optional segments of SQL with further parameter mappings. It allows for as complex of a query mapping as the developer can come up with. It even has controls in the report configuration to determine whether a given query will have the final mappings via a PreparedStatement or simply ran as a pre-built query.

For the sample Http request values:

showOwner: true
serverId: 20
appId: 1,2,3,5,7,11,13

It would produce the following SQL:

select app.name as "App", 
       app.owner as "Owner", 
       sv.name as "Server", sum(act.trans_ct) as "Trans"
  from activity_records act, servers sv, applications app
 where act.server_id = sv.id
   and act.app_id = app.id
   and sv.id = 20
   and app.id in (1,2,3,5,7,11,13)
 group by app.name,  app.owner,  sv.name
 order by app.name, sv.name

I really think that Spring or Hibernate or one of those frameworks should offer a more robust mapping mechanism that verifies types, allows for complex data types like arrays and other such features. I wrote my engine for only my purposes, it isn't quite read for general release. It only works with Oracle queries at the moment and all of the code belongs to a big corporation. Someday I may take my ideas and build a new open source framework, but I'm hoping one of the existing big players will take up the challenge.

The difference is that functionOne is a function expression and so only defined when that line is reached, whereas functionTwo is a function declaration and is defined as soon as its surrounding function or script is executed (due to hoisting).

For example, a function expression:

// TypeError: functionOne is not a function_x000D_
functionOne();_x000D_
_x000D_
var functionOne = function() {_x000D_
  console.log("Hello!");_x000D_
};

And, a function declaration:

// Outputs: "Hello!"_x000D_
functionTwo();_x000D_
_x000D_
function functionTwo() {_x000D_
  console.log("Hello!");_x000D_
}

Historically, function declarations defined within blocks were handled inconsistently between browsers. Strict mode (introduced in ES5) resolved this by scoping function declarations to their enclosing block.

'use strict';    _x000D_
{ // note this block!_x000D_
  function functionThree() {_x000D_
    console.log("Hello!");_x000D_
  }_x000D_
}_x000D_
functionThree(); // ReferenceError

Since your event listener is 'click', you can:

someObj.setAttribute("onclick", "function(parameter)");

This is a bit outside the scope of your question, but to avoid any potential confusion for readers who are new to VBA: End and End Sub are not the same. They don't perform the same task.

End puts a stop to ALL code execution and you should almost always use Exit Sub (or Exit Function, respectively).

End halts ALL exectution. While this sounds tempting to do it also clears all global and static variables. (source)

See also the MSDN dox for the End Statement

When executed, the End statement resets allmodule-level variables and all static local variables in allmodules. To preserve the value of these variables, use the Stop statement instead. You can then resume execution while preserving the value of those variables.

Note The End statement stops code execution abruptly, without invoking the Unload, QueryUnload, or Terminate event, or any other Visual Basic code. Code you have placed in the Unload, QueryUnload, and Terminate events offorms andclass modules is not executed. Objects created from class modules are destroyed, files opened using the Open statement are closed, and memory used by your program is freed. Object references held by other programs are invalidated.

Nor is End Sub and Exit Sub the same. End Sub can't be called in the same way Exit Sub can be, because the compiler doesn't allow it.

This again means you have to Exit Sub, which is a perfectly legal operation:

Exit Sub
Immediately exits the Sub procedure in which it appears. Execution continues with the statement following the statement that called the Sub procedure. Exit Sub can be used only inside a Sub procedure.

Additionally, and once you get the feel for how procedures work, obviously, End Sub does not clear any global variables. But it does clear local (Dim'd) variables:

End Sub
Terminates the definition of this procedure.

same thing happened to me, but all that was happening is that the private key got lost from the keychain on my local machine.

ssh-add -K

re-added the key, then the ssh command to connect returned to work.

when your document is ready that doesn't mean that your iframe is ready too,
so you should listen to the iframe load event then access your contents:

$(function() {
    $("#my-iframe").bind("load",function(){
        $(this).contents().find("[tokenid=" + token + "]").html();
    });
});

Use open(fn, 'rb').read().decode('utf-8') instead of just open(fn).read()

In my case I wanted to compare values in cells of column E with Cells in Column G

Highlight the selection of cells to be checked in column E.

Select Conditional Format: Highlight cell rules Select one of the choices in my case it was greater than. In the left hand field of pop up use =indirect("g"&row()) where g was the row I was comparing against.

Now the row you are formatting will highlight based on if it is greater than the selection in row G

This works for every cell in Column E compared to cell in Column G of the selection you made for column E.

If G2 is greater than E2 it formats

G3 is greater than E3 it formats etc

There is also a constructor overload for List that will work... But I guess this would required a strong typed array.

//public List(IEnumerable<T> collection)
var intArray = new[] { 1, 2, 3, 4, 5 };
var list = new List<int>(intArray);

... for Array class

var intArray = Array.CreateInstance(typeof(int), 5);
for (int i = 0; i < 5; i++)
    intArray.SetValue(i, i);
var list = new List<int>((int[])intArray);

[+]is simpler

    String s = "ddjdjdj+kfkfkf";

    if(s.contains ("+"))
    {
        String parts[] = s.split("[+]");
        s =  parts[0]; // i want to strip part after  +
    }
    System.out.println(s);

The following is OK in HTML4, but not in XHTML. Check your editor.

<input type=button value="Submit" />

Here is example code you could run to make such test:

var f = 10000000;
var p = new int[f];

for(int i = 0; i < f; ++i)
{
    p[i] = i % 2;
}

var time = DateTime.Now;
p.Sum();
Console.WriteLine(DateTime.Now - time);

int x = 0;
time = DateTime.Now;
foreach(var item in p){
   x += item;
}
Console.WriteLine(DateTime.Now - time);

x = 0;
time = DateTime.Now;
for(int i = 0, j = f; i < j; ++i){
   x += p[i];
}
Console.WriteLine(DateTime.Now - time);

The same example for complex object is:

void Main()
{
    var f = 10000000;
    var p = new Test[f];

    for(int i = 0; i < f; ++i)
    {
        p[i] = new Test();
        p[i].Property = i % 2;
    }

    var time = DateTime.Now;
    p.Sum(k => k.Property);
    Console.WriteLine(DateTime.Now - time);

    int x = 0;
    time = DateTime.Now;
    foreach(var item in p){
        x += item.Property;
    }
    Console.WriteLine(DateTime.Now - time);

    x = 0;
    time = DateTime.Now;
    for(int i = 0, j = f; i < j; ++i){
        x += p[i].Property;
    }
    Console.WriteLine(DateTime.Now - time);
}

class Test
{
    public int Property { get; set; }
}

My results with compiler optimizations off are:

00:00:00.0570370 : Sum()
00:00:00.0250180 : Foreach()
00:00:00.0430272 : For(...)

and for second test are:

00:00:00.1450955 : Sum()
00:00:00.0650430 : Foreach()
00:00:00.0690510 : For()

it looks like LINQ is generally slower than foreach(...) but what is weird for me is that foreach(...) appears to be faster than for loop.

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

In my case I tried to run npm i [email protected] and got the error because the dev server was running in another terminal on vsc. Hit ctrl+c, y to stop it in that terminal, and then installation works.

Have you tried using the ConflictResolution:=xlLocalSessionChanges parameter in the SaveAs method?

As so:

Public Sub example()
Application.DisplayAlerts = False
Application.EnableEvents = False

For Each element In sArray
    XLSMToXLSX(element)
Next element

Application.DisplayAlerts = False
Application.EnableEvents = False
End Sub

Sub XLSMToXLSX(ByVal file As String)
    Do While WorkFile <> ""
        If Right(WorkFile, 4) <> "xlsx" Then
            Workbooks.Open Filename:=myPath & WorkFile

            Application.DisplayAlerts = False
            Application.EnableEvents = False

            ActiveWorkbook.SaveAs Filename:= _
            modifiedFileName, FileFormat:= _
            xlOpenXMLWorkbook, CreateBackup:=False, _
            ConflictResolution:=xlLocalSessionChanges

            Application.DisplayAlerts = True
            Application.EnableEvents = True

            ActiveWorkbook.Close
        End If
        WorkFile = Dir()
    Loop
End Sub

$id = $access_data['Privilege']['id']; 

if(!in_array($id,$user_access_arr));
    $user_access_arr[] = $id;
    $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
    return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));

You need to enable the APIs from link:

https://console.cloud.google.com/apis/library?

• First, str in Python is represented in Unicode.
• Second, UTF-8 is an encoding standard to encode Unicode string to bytes. There are many encoding standards out there (e.g. UTF-16, ASCII, SHIFT-JIS, etc.).

When the client sends data to your server and they are using UTF-8, they are sending a bunch of bytes not str.

You received a str because the "library" or "framework" that you are using, has implicitly converted some random bytes to str.

Under the hood, there is just a bunch of bytes. You just need ask the "library" to give you the request content in bytes and you will handle the decoding yourself (if library can't give you then it is trying to do black magic then you shouldn't use it).

• Decode UTF-8 encoded bytes to str: bs.decode('utf-8')
• Encode str to UTF-8 bytes: s.encode('utf-8')

I already use the function redirect() of JavaScript. It's working.

<script type="text/javascript">
    $(function () {
        //It's similar to HTTP redirect
        window.location.replace("http://www.Technomark.in");

        //It's similar to clicking on a link
        window.location.href = "Http://www.Technomark.in";
    })
</script>

As far as I know, this is the C++ Runtime Library. So it depends on the compiler you use to create your program (A new version will include some C++0x stuff, an older version will probably not for instance. It depends of the compiler and of its version).

If you use MinGW then you should use the libstdc++-6.dll found into the folder of this compiler. MinGW/bin folder should be the place to search for it on your computer.

If you copy this file in the same directory as your executable, it should be OK.

This is the most simple solution that use:

// Use this as first line upon load of page

$sort = $_GET['s'];

// Then simply sort according to that variable

$sql="SELECT * FROM tracks ORDER BY $sort";

echo '<tr>';
echo '<td><a href="report_tracks.php?s=title">Title</a><td>';
echo '<td><a href="report_tracks.php?s=album">Album</a><td>';
echo '<td><a href="report_tracks.php?s=artist">Artist</a><td>';
echo '<td><a href="report_tracks.php?s=count">Count</a><td>';
echo '</tr>';

For global installation : npm install webpack-dev-server -g

For local installation npm install --save-dev webpack

When you refer webpack in package.json file, it tries to look it in location node_modules\.bin\

After local installation, file wbpack will get created in location: \node_modules\.bin\webpack

My answer is similar to Paolo's answer.

I think module requests is much better. It's based on urllib3. You can try this:

>>> from requests.utils import quote
>>> quote('/test')
'/test'
>>> quote('/test', safe='')
'%2Ftest'

**Use Spread Operators| ES6 **

let datesVar = [ 2017-10-26T03:37:10.876Z,
  2017-10-27T03:37:10.876Z,
  2017-10-23T03:37:10.876Z,
  2015-10-23T03:37:10.876Z ]

Math.min(...datesVar);

That will give the minimum date from the array.

Its shorthand Math.min.apply(null, ArrayOfdates);

You will need to know something about the URLs, like do they have a specific directory or some query string element because you have to match for something. Otherwise you will have to redirect on the 404. If this is what is required then do something like this in your .htaccess:

ErrorDocument 404 /index.php

An error page redirect must be relative to root so you cannot use www.mydomain.com.

If you have a pattern to match too then use 301 instead of 302 because 301 is permanent and 302 is temporary. A 301 will get the old URLs removed from the search engines and the 302 will not.

Mod Rewrite Reference: http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html

Modern answer and overview

a) Java-8 (java.time-package)

LocalDate start = LocalDate.of(1996, 2, 29);
LocalDate end = LocalDate.of(2014, 2, 28); // use for age-calculation: LocalDate.now()
long years = ChronoUnit.YEARS.between(start, end);
System.out.println(years); // 17

Note that the expression LocalDate.now() is implicitly related to the system timezone (which is often overlooked by users). For clarity it is generally better to use the overloaded method now(ZoneId.of("Europe/Paris")) specifying an explicit timezone (here "Europe/Paris" as example). If the system timezone is requested then my personal preference is to write LocalDate.now(ZoneId.systemDefault()) to make the relation to the system timezone clearer. This is more writing effort but makes reading easier.

b) Joda-Time

Please note that the proposed and accepted Joda-Time-solution yields a different computation result for the dates shown above (a rare case), namely:

LocalDate birthdate = new LocalDate(1996, 2, 29);
LocalDate now = new LocalDate(2014, 2, 28); // test, in real world without args
Years age = Years.yearsBetween(birthdate, now);
System.out.println(age.getYears()); // 18

I consider this as a small bug but the Joda-team has a different view on this weird behaviour and does not want to fix it (weird because the day-of-month of end date is smaller than of start date so the year should be one less). See also this closed issue.

c) java.util.Calendar etc.

For comparison see the various other answers. I would not recommend using these outdated classes at all because the resulting code is still errorprone in some exotic cases and/or way too complex considering the fact that the original question sounds so simple. In year 2015 we have really better libraries.

d) About Date4J:

The proposed solution is simple but will sometimes fail in case of leap years. Just evaluating the day of year is not reliable.

e) My own library Time4J:

This works similar to Java-8-solution. Just replace LocalDate by PlainDate and ChronoUnit.YEARS by CalendarUnit.YEARS. However, getting "today" requires an explicit timezone reference.

PlainDate start = PlainDate.of(1996, 2, 29);
PlainDate end = PlainDate.of(2014, 2, 28);
// use for age-calculation (today): 
// => end = SystemClock.inZonalView(EUROPE.PARIS).today();
// or in system timezone: end = SystemClock.inLocalView().today();
long years = CalendarUnit.YEARS.between(start, end);
System.out.println(years); // 17

userType = (user.Type == 0) ? "Admin" : (user.type == 1) ? "User" : "Admin";

should do the trick.

Always keep in mind when you want to overcome this error, the default value of indexing and range starts from 0, so if total items is 100 then l[99] and range(99) will give you access up to the last element.

whenever you get this type of error please cross check with items that comes between/middle in range, and insure that their index is not last if you get output then you have made perfect error that mentioned above.

Building on Constantin's answer, here's the essence of what I learned while transitioning to Notepad++ as my primary HTML editor.

Install Notepad++ 32-bit

There's no 64-bit version of Tidy2 and some other popular plugins. The 32-bit version of NPP has few practical downsides, so axe the 64-bit version.

Install the Plugin Manager

Plugin Manager isn't strictly necessary for plugin usage. It does make things much easier, though.

Plugin Manager was eliminated from the core package apparently because the developer didn't like some included attribution linking.

You may notice that Plugin Manager plugin has been removed from the official distribution. The reason is Plugin Manager contains the advertising in its dialog. I hate Ads in applications, and I ensure you that there was no, and there will never be Ads in Notepad++.

It's a manual install, but it's not difficult.

1. Download the UNI (32-bit) zip package and extract it. Inside you'll see folders called plugins and updater. Each contains one file.
2. Drag those two files to the respective identically-named folders in your Notepad++ installation directory. Typically that's C:\Program Files (x86)\Notepad++.
3. Restart Notepad++ and follow any install/update prompts.

Now you'll see a new entry under Plugins for Plugin Manager.

Install Tidy2 (or your preferred alternative)

In Plugin Manager, check the box for Tidy2. Click Install. Restart when prompted.

To use Tidy2, select one of the preconfigured profiles in its Plugins submenu item, or create your own.

What you are asking is pretty straight forward

1. execute query against your db to get resultset or use API to get the resultset

2. loop through the resultset or simply the result using php

3. In each iteration simply format the output as an element

hope this helps :)

Try this:

Dim Lastrow As Integer
Lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row

Range("A2:L" & Lastrow).Select

Let's pretend that the value of Lastrow is 50. When you use the following:

Range("A2:L2" & Lastrow).Select

Then it is selecting a range from A2 to L250.

All of the other answers are basically right but I don't think anyone's directly answered your original question.

Assuming that "date_and_time" in your example is a column with type DATE or TIMESTAMP, I think you just need to change this:

to_char(date_and_time + (.000694 * 31))

to this:

to_char(date_and_time + (.000694 * 31), 'DD-MON-YYYY HH24:MI')

It sounds like your default date format uses the "HH" code for the hour, not "HH24".

Also, I think your constant term is both confusing and imprecise. I guess what you did is calculate that (.000694) is about the value of a minute, and you are multiplying it by the number of minutes you want to add (31 in the example, although you said 30 in the text).

I would also start with a day and divide it into the units you want within your code. In this case, (1/48) would be 30 minutes; or if you wanted to break it up for clarity, you could write ( (1/24) * (1/2) ).

This would avoid rounding errors (except for those inherent in floating point which should be meaningless here) and is clearer, at least to me.

After installing weblogic and forms server on a Linux machine we met some problems initializing sqlplus and tnsping. We altered the bash_profile in a way that the forms_home acts as the oracle home. It works fine, both commands (sqlplus and tnsping) are executable for user oracle

An ioctl, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.

An alternative is the sysfs interface, where you set up a file under /sys/ and read/write that to get information from and to the driver. An example of how to set this up:

static ssize_t mydrvr_version_show(struct device *dev,
        struct device_attribute *attr, char *buf)
{
    return sprintf(buf, "%s\n", DRIVER_RELEASE);
}

static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);

And during driver setup:

device_create_file(dev, &dev_attr_version);

You would then have a file for your device in /sys/, for example, /sys/block/myblk/version for a block driver.

Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl or libnl3 libraries.

SELECT GETVARIABLE('SYSIBM.VERSION') FROM SYSIBM.SYSDUMMY1

It's not smart to have python code inside java. Wrap your python code with flask or other web framework to make it as a microservice. Make your java program able to call this microservice (e.g. via REST).

Beleive me, this is much simple and will save you tons of issues. And the codes are loosely coupled so they are scalable.

Updated on Mar 24th 2020: According to @stx's comment, the above approach is not suitable for massive data transfer between client and server. Here is another approach I recommended: Connecting Python and Java with Rust(C/C++ also ok). https://medium.com/@shmulikamar/https-medium-com-shmulikamar-connecting-python-and-java-with-rust-11c256a1dfb0

If you're using the iframe embed api, you can put html5:1 as one of the playerVars arguments, like so:

player = new YT.Player('player', {
    height: '390',
    width: '640',
    videoId: '<VIDEO ID>',
    playerVars: {
        html5: 1
    },
});

Totally works.

Try this:

[TestMethod]
public void TestSomething()
{
    try
    {
        YourMethodCall();
        Assert.IsTrue(true);
    }
    catch {
        Assert.IsTrue(false);
    }
}

If you are only interested to see the files that differ, you may use:

diff -qr dir_one dir_two | sort

Option "q" will only show the files that differ but not the content that differ, and "sort" will arrange the output alphabetically.

The for loop is getting one extra run. Change

for (x=0;x<=InvForm.SelBranch.length;x++)

to

for (x=0; x < InvForm.SelBranch.length; x++)

Edit 2019 Since this answer has gained traction, I'll add a function, which might simplify the usage for some

from datetime import datetime

def getDuration(then, now = datetime.now(), interval = "default"):

    # Returns a duration as specified by variable interval
    # Functions, except totalDuration, returns [quotient, remainder]

    duration = now - then # For build-in functions
    duration_in_s = duration.total_seconds() 
    
    def years():
      return divmod(duration_in_s, 31536000) # Seconds in a year=31536000.

    def days(seconds = None):
      return divmod(seconds if seconds != None else duration_in_s, 86400) # Seconds in a day = 86400

    def hours(seconds = None):
      return divmod(seconds if seconds != None else duration_in_s, 3600) # Seconds in an hour = 3600

    def minutes(seconds = None):
      return divmod(seconds if seconds != None else duration_in_s, 60) # Seconds in a minute = 60

    def seconds(seconds = None):
      if seconds != None:
        return divmod(seconds, 1)   
      return duration_in_s

    def totalDuration():
        y = years()
        d = days(y[1]) # Use remainder to calculate next variable
        h = hours(d[1])
        m = minutes(h[1])
        s = seconds(m[1])

        return "Time between dates: {} years, {} days, {} hours, {} minutes and {} seconds".format(int(y[0]), int(d[0]), int(h[0]), int(m[0]), int(s[0]))

    return {
        'years': int(years()[0]),
        'days': int(days()[0]),
        'hours': int(hours()[0]),
        'minutes': int(minutes()[0]),
        'seconds': int(seconds()),
        'default': totalDuration()
    }[interval]

# Example usage
then = datetime(2012, 3, 5, 23, 8, 15)
now = datetime.now()

print(getDuration(then)) # E.g. Time between dates: 7 years, 208 days, 21 hours, 19 minutes and 15 seconds
print(getDuration(then, now, 'years'))      # Prints duration in years
print(getDuration(then, now, 'days'))       #                    days
print(getDuration(then, now, 'hours'))      #                    hours
print(getDuration(then, now, 'minutes'))    #                    minutes
print(getDuration(then, now, 'seconds'))    #                    seconds

Warning: Caveat about built-in .seconds and .microseconds
datetime.seconds and datetime.microseconds are capped to [0,86400) and [0,10^6) respectively.

They should be used carefully if timedelta is bigger than the max returned value.

Examples:

end is 1h and 200µs after start:

>>> start = datetime(2020,12,31,22,0,0,500)
>>> end = datetime(2020,12,31,23,0,0,700)
>>> delta = end - start
>>> delta.microseconds
RESULT: 200
EXPECTED: 3600000200

end is 1d and 1h after start:

>>> start = datetime(2020,12,30,22,0,0)
>>> end = datetime(2020,12,31,23,0,0)
>>> delta = end - start
>>> delta.seconds
RESULT: 3600
EXPECTED: 90000

First download the JavaMail API and make sure the relevant jar files are in your classpath.

Here's a full working example using GMail.

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class Main {

    private static String USER_NAME = "*****";  // GMail user name (just the part before "@gmail.com")
    private static String PASSWORD = "********"; // GMail password
    private static String RECIPIENT = "[email protected]";

    public static void main(String[] args) {
        String from = USER_NAME;
        String pass = PASSWORD;
        String[] to = { RECIPIENT }; // list of recipient email addresses
        String subject = "Java send mail example";
        String body = "Welcome to JavaMail!";

        sendFromGMail(from, pass, to, subject, body);
    }

    private static void sendFromGMail(String from, String pass, String[] to, String subject, String body) {
        Properties props = System.getProperties();
        String host = "smtp.gmail.com";
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.user", from);
        props.put("mail.smtp.password", pass);
        props.put("mail.smtp.port", "587");
        props.put("mail.smtp.auth", "true");

        Session session = Session.getDefaultInstance(props);
        MimeMessage message = new MimeMessage(session);

        try {
            message.setFrom(new InternetAddress(from));
            InternetAddress[] toAddress = new InternetAddress[to.length];

            // To get the array of addresses
            for( int i = 0; i < to.length; i++ ) {
                toAddress[i] = new InternetAddress(to[i]);
            }

            for( int i = 0; i < toAddress.length; i++) {
                message.addRecipient(Message.RecipientType.TO, toAddress[i]);
            }

            message.setSubject(subject);
            message.setText(body);
            Transport transport = session.getTransport("smtp");
            transport.connect(host, from, pass);
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();
        }
        catch (AddressException ae) {
            ae.printStackTrace();
        }
        catch (MessagingException me) {
            me.printStackTrace();
        }
    }
}

Naturally, you'll want to do more in the catch blocks than print the stack trace as I did in the example code above. (Remove the catch blocks to see which method calls from the JavaMail API throw exceptions so you can better see how to properly handle them.)

Thanks to @jodonnel and everyone else who answered. I'm giving him a bounty because his answer led me about 95% of the way to a complete answer.

Is there maybe a way to grab the rendered page from the internet explorer rendering engine and send it to a PDF-Printer tool automatically?

This is how ActivePDF works, which is good means that you know what you'll get, and it actually has reasonable styling support.

It is also one of the few packages I found (when looking a few years back) that actually supports the various page-break CSS commands.

Unfortunately, the ActivePDF software is very frustrating - since it has to launch the IE browser in the background for conversions it can be quite slow, and it is not particularly stable either.

There is a new version currently in Beta which is supposed to be much better, but I've not actually had a chance to try it out, so don't know how much of an improvement it is.

Can you provide a link ? thanks I can take a look Most likely your css selector isnt strong enough or can you try

padding:0!important;

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

Neither of these options is correct. You're trying to implement a synchronous interface asynchronously. Don't do that. The problem is that when DoOperation() returns, the operation won't be complete yet. Worse, if an exception happens during the operation (which is very common with IO operations), the user won't have a chance to deal with that exception.

What you need to do is to modify the interface, so that it is asynchronous:

interface IIO
{
    Task DoOperationAsync(); // note: no async here
}

class IOImplementation : IIO
{
    public async Task DoOperationAsync()
    {
        // perform the operation here
    }
}

This way, the user will see that the operation is async and they will be able to await it. This also pretty much forces the users of your code to switch to async, but that's unavoidable.

Also, I assume using StartNew() in your implementation is just an example, you shouldn't need that to implement asynchronous IO. (And new Task() is even worse, that won't even work, because you don't Start() the Task.)

I used this

:top
cls
type G:\empty.txt
type I:\empty.txt
timeout /T 500
goto top

Well, as it was said before, you can't GROUP by literals, I think that you are confused cause you can ORDER by 1, 2, 3. When you use functions as your columns, you need to GROUP by the same expression. Besides, the HAVING clause is wrong, you can only use what is in the agreggations. In this case, your query should be like this:

SELECT 
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound,
MAX(qvalues.rid) MaxRid
FROM batchinfo join qvalues 
ON batchinfo.rowid=qvalues.rowid
WHERE LEN(datapath)>4
GROUP BY 
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound

You should always include the table name in the SQL query when dealing with associations.

Indeed if another table has the user_id column and you join both tables, you will have an ambiguous column name in the SQL query (i.e. troubles).

So, in your example:

GroupUser.where("groups_users.user_id != ?", me)

Or a bit more verbose:

GroupUser.where("#{table_name}.user_id IS NOT ?", me)

Note that if you are using a hash, you don't need to worry about that because Rails takes care of it for you:

GroupUser.where(user: me)

In Rails 4, as said by @dr4k3, the query method not has been added:

GroupUser.where.not(user: me)

package com.acn.demo.action;

public class RemoveCharFromString {

    static String input = "";
    public static void main(String[] args) {
        input = "abadbbeb34erterb";
        char token = 'b';
        removeChar(token);
    }

    private static void removeChar(char token) {
        // TODO Auto-generated method stub
        System.out.println(input);
        for (int i=0;i<input.length();i++) {
            if (input.charAt(i) == token) {
            input = input.replace(input.charAt(i), ' ');
                System.out.println("MATCH FOUND");
            }
            input = input.replaceAll(" ", "");
            System.out.println(input);
        }
    }
}

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

You have a couple of options...

1) You need to call the destroy() method not remove() so...

$('#date').datepicker('destroy');

Then call your method to recreate the datepicker object.

2) You can update the property of the existing object via

$('#date').datepicker('option', 'minDate', new Date(startDate));
$('#date').datepicker('option', 'maxDate', new Date(endDate));

or...

$('#date').datepicker('option', { minDate: new Date(startDate),
                                  maxDate: new Date(endDate) });

You could also disable user select on all elements:

* {
    -webkit-touch-callout:none;
    -webkit-user-select:none;
    -moz-user-select:none;
    -ms-user-select:none;
    user-select:none;
}

And than enable it on the elements you do want the user to be able to select:

input, textarea /*.contenteditable?*/ {
    -webkit-touch-callout:default;
    -webkit-user-select:text;
    -moz-user-select:text;
    -ms-user-select:text;
    user-select:text;
}

angle = Math.toDegrees(Math.atan2(target.x - x, target.y - y));

now for orientation of circular values to keep angle between 0 and 359 can be:

angle = angle + Math.ceil( -angle / 360 ) * 360

You need to initialize whatever members you have in your struct, e.g.:

struct MyStruct {
  private:
    int someInt_;
    float someFloat_;

  public:
    MyStruct(): someInt_(0), someFloat_(1.0) {} // Initializer list will set appropriate values

};

Actually the list of parameters could be accessed with $1 $2 ... etc.
Which is exactly equivalent to:

${!i}

So, the list of parameters could be changed with set,
and ${!i} is the correct way to access them:

$ set -- aa bb cc dd 55 ff gg hh ii jjj kkk lll
$ for ((i=0;i<=$#;i++)); do echo "$#" "$i" "${!i}"; done

12 1 aa
12 2 bb
12 3 cc
12 4 dd
12 5 55
12 6 ff
12 7 gg
12 8 hh
12 9 ii
12 10 jjj
12 11 kkk
12 12 lll

For your specific case, this could be used (without the need for arrays), to set the list of arguments when none was given:

if [ "$#" -eq 0 ]; then
    set -- defaultarg1 defaultarg2
fi

which translates to this even simpler expression:

[ "$#" == "0" ] && set -- defaultarg1 defaultarg2

You could use the Mutex class, but you will soon find out that you will need to implement the code to pass the arguments and such yourself. Well, I learned a trick when programming in WinForms when I read Chris Sell's book. This trick uses logic that is already available to us in the framework. I don't know about you, but when I learn about stuff I can reuse in the framework, that is usually the route I take instead of reinventing the wheel. Unless of course it doesn't do everything I want.

When I got into WPF, I came up with a way to use that same code, but in a WPF application. This solution should meet your needs based off your question.

First, we need to create our application class. In this class we are going override the OnStartup event and create a method called Activate, which will be used later.

public class SingleInstanceApplication : System.Windows.Application
{
    protected override void OnStartup(System.Windows.StartupEventArgs e)
    {
        // Call the OnStartup event on our base class
        base.OnStartup(e);

        // Create our MainWindow and show it
        MainWindow window = new MainWindow();
        window.Show();
    }

    public void Activate()
    {
        // Reactivate the main window
        MainWindow.Activate();
    }
}

Second, we will need to create a class that can manage our instances. Before we go through that, we are actually going to reuse some code that is in the Microsoft.VisualBasic assembly. Since, I am using C# in this example, I had to make a reference to the assembly. If you are using VB.NET, you don't have to do anything. The class we are going to use is WindowsFormsApplicationBase and inherit our instance manager off of it and then leverage properties and events to handle the single instancing.

public class SingleInstanceManager : Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase
{
    private SingleInstanceApplication _application;
    private System.Collections.ObjectModel.ReadOnlyCollection<string> _commandLine;

    public SingleInstanceManager()
    {
        IsSingleInstance = true;
    }

    protected override bool OnStartup(Microsoft.VisualBasic.ApplicationServices.StartupEventArgs eventArgs)
    {
        // First time _application is launched
        _commandLine = eventArgs.CommandLine;
        _application = new SingleInstanceApplication();
        _application.Run();
        return false;
    }

    protected override void OnStartupNextInstance(StartupNextInstanceEventArgs eventArgs)
    {
        // Subsequent launches
        base.OnStartupNextInstance(eventArgs);
        _commandLine = eventArgs.CommandLine;
        _application.Activate();
    }
}

Basically, we are using the VB bits to detect single instance's and process accordingly. OnStartup will be fired when the first instance loads. OnStartupNextInstance is fired when the application is re-run again. As you can see, I can get to what was passed on the command line through the event arguments. I set the value to an instance field. You could parse the command line here, or you could pass it to your application through the constructor and the call to the Activate method.

Third, it's time to create our EntryPoint. Instead of newing up the application like you would normally do, we are going to take advantage of our SingleInstanceManager.

public class EntryPoint
{
    [STAThread]
    public static void Main(string[] args)
    {
        SingleInstanceManager manager = new SingleInstanceManager();
        manager.Run(args);
    }
}

Well, I hope you are able to follow everything and be able use this implementation and make it your own.

I like Jesper's explanation in layman terms

By improvising examples from Jesper's answer,

class House {
// blue print for House Objects
}

class Car {
// blue print for Instances of Class Car 
}

House myHouse = new House();
Car myCar = new Car();

myHouse and myCar are objects

myHouse is an instance of House (relates Object-myHouse to its Class-House) myCar is an instance of Car

in short

"myHouse is an instance of Class House" which is same as saying "myHouse is an Object of type House"

the best away now.

this.setState({ myArr: [...this.state.myArr, new_value] })

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

The same error may occur after renaming packages. Check the value in string.xml for android:authorities from AndroidManifest.xml.

<provider
        android:authorities="@string/content_authority"
        android:name=".data.Provider"
        ... />

In string.xml the value should be the same as your package name, declared in manifest.

<string name="content_authority">com.whatever.android.sunshine.app</string>

I would like to add an answer to this thread to specifically mention which of the above threads helped me solve the issue and the order in which they can be followed to properly understand the root cause and fix it once and for all:

I was able to get my rich preview while sharing the link on social media with this solution.

I followed various options in this thread and below are the closest to the right answer and they all contributed to the end result:

1. Tags required (Main tag to focus on - og:image)
2. Image parameters
3. Tool that will definitely help
4. How to correctly give the image path
5. Root cause and solution

This will hopefully save someone the time needed to scroll through and find the right set of answers and the effort required for all the trial and errors.

This is totally OK.

1. The first group (m.group(0)) always captures the whole area that is covered by your regular expression. In this case, it's the whole string.
2. Regular expressions are greedy by default, meaning that the first group captures as much as possible without violating the regex. The (.*)(\\d+) (the first part of your regex) covers the ...QT300 int the first group and the 0 in the second.
3. You can quickly fix this by making the first group non-greedy: change (.*) to (.*?).

For more info on greedy vs. lazy, check this site.

Do you need to fake an anchor click? From the thickbox site:

ThickBox can be invoked from a link element, input element (typically a button), and the area element (image maps).

If that is acceptable it should be as easy as putting the thickbox class on the input itself:

<input id="thickboxButton" type="button" class="thickbox" value="Click me">

If not, I would recommend using Firebug and placing a breakpoint in the onclick method of the anchor element to see if it's only triggered on the first click.

Edit:

Okay, I had to try it for myself and for me pretty much exactly your code worked in both Chrome and Firefox:

<html>
<head>
<link rel="stylesheet" href="thickbox.css" type="text/css" media="screen" />
</head>
<body>
<script src="jquery-latest.pack.js" type="text/javascript"></script>
<script src="thickbox.js" type="text/javascript"></script>
<input onclick="$('#thickboxId').click();" type="button" value="Click me">
<a id="thickboxId" href="myScript.php" class="thickbox" title="">Link</a>
</body>
</html>

The window pop ups no matter if I click the input or the anchor element. If the above code works for you, I suggest your error lies elsewhere and that you try to isolate the problem.

Another possibly is that we are using different versions of jquery/thickbox. I am using what I got from the thickbox page - jquery 1.3.2 and thickbox 3.1.

If your cascading deletes nuke a product because it was a member of a category that was killed, then you've set up your foreign keys improperly. Given your example tables, you should have the following table setup:

CREATE TABLE categories (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE products (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE categories_products (
    category_id int unsigned not null,
    product_id int unsigned not null,
    PRIMARY KEY (category_id, product_id),
    KEY pkey (product_id),
    FOREIGN KEY (category_id) REFERENCES categories (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE,
    FOREIGN KEY (product_id) REFERENCES products (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE
)Engine=InnoDB;

This way, you can delete a product OR a category, and only the associated records in categories_products will die alongside. The cascade won't travel farther up the tree and delete the parent product/category table.

e.g.

products: boots, mittens, hats, coats
categories: red, green, blue, white, black

prod/cats: red boots, green mittens, red coats, black hats

If you delete the 'red' category, then only the 'red' entry in the categories table dies, as well as the two entries prod/cats: 'red boots' and 'red coats'.

The delete will not cascade any farther and will not take out the 'boots' and 'coats' categories.

comment followup:

you're still misunderstanding how cascaded deletes work. They only affect the tables in which the "on delete cascade" is defined. In this case, the cascade is set in the "categories_products" table. If you delete the 'red' category, the only records that will cascade delete in categories_products are those where category_id = red. It won't touch any records where 'category_id = blue', and it would not travel onwards to the "products" table, because there's no foreign key defined in that table.

Here's a more concrete example:

categories:     products:
+----+------+   +----+---------+
| id | name |   | id | name    |
+----+------+   +----+---------+
| 1  | red  |   | 1  | mittens |
| 2  | blue |   | 2  | boots   |
+---++------+   +----+---------+

products_categories:
+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 1          | 2           | // blue mittens
| 2          | 1           | // red boots
| 2          | 2           | // blue boots
+------------+-------------+

Let's say you delete category #2 (blue):

DELETE FROM categories WHERE (id = 2);

the DBMS will look at all the tables which have a foreign key pointing at the 'categories' table, and delete the records where the matching id is 2. Since we only defined the foreign key relationship in products_categories, you end up with this table once the delete completes:

+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 2          | 1           | // red boots
+------------+-------------+

There's no foreign key defined in the products table, so the cascade will not work there, so you've still got boots and mittens listed. There's just no 'blue boots' and no 'blue mittens' anymore.

If you don't want to build your server side, like only developing on a client side (web app or a mobile app) , you could choose an Implicit Authentication .

As the document saying , first make a https request with

https://api.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=token

Fill in your CLIENT-ID and REDIRECT-URL you designated.

Then that's going to the log in page , but the most important thing is how to get the access token after the user correctly logging in.

After the user click the log in button with both correct account and password, the web page will redirect to the url you designated followed by a new access token.

http://your-redirect-uri#access_token=ACCESS-TOKEN

I'm not familiar with javascript , but in Android studio , that's an easy way to add a listener which listen to the event the web page override the url to the new url (redirect event) , then it will pass the redirect url string to you , so you can easily split it to get the access-token like:

String access_token = url.split("=")[1];

Means to break the url into the string array in each "=" character , then the access token obviously exists at [1].

Calendar calendar = Calendar.getInstance();

DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), R.style.DatePickerDialogTheme, new DatePickerDialog.OnDateSetListener() {
  public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    Calendar newDate = Calendar.getInstance();
    newDate.set(year, monthOfYear, dayOfMonth);

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy");
    String date = simpleDateFormat.format(newDate.getTime());
  }
}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));

datePickerDialog.show();

And use this style:

<style name="DatePickerDialogTheme" parent="Theme.AppCompat.Light.Dialog">
  <item name="colorAccent">@color/colorPrimary</item>
</style>

go to FileZilla and select which folder you will be give 777 permission, then right click set permission 777 and select check box, then ok.

Check the C-drive inside C:\inetpub\wwwroot and remove all unnecessary folders from it, else remove unnecessary host files or folders from IIS.

To declare a type variable property, mark the declaration with the static declaration modifier. Classes may mark type computed properties with the class declaration modifier instead to allow subclasses to override the superclass’s implementation. Type properties are discussed in Type Properties.

NOTE
In a class declaration, the keyword static has the same effect as marking the declaration with both the class and final declaration modifiers.

For me, with Android Studio 1.5.1, the solution was to recreate the whole project with a slightly different name.

I think it didn't handle the app name "Kommentator_AS", because several places the package was named"Kommentator" instead.

The .net framework supports JSON through JavaScriptSerializer. Here is a good example to get you started.

using System.Collections.Generic;
using System.Web.Script.Serialization;

namespace GoogleTranslator.GoogleJSON
{
    public class FooTest
    {
        public void Test()
        {
            const string json = @"{
              ""DisplayFieldName"" : ""ObjectName"", 
              ""FieldAliases"" : {
                ""ObjectName"" : ""ObjectName"", 
                ""ObjectType"" : ""ObjectType""
              }, 
              ""PositionType"" : ""Point"", 
              ""Reference"" : {
                ""Id"" : 1111
              }, 
              ""Objects"" : [
                {
                  ""Attributes"" : {
                    ""ObjectName"" : ""test name"", 
                    ""ObjectType"" : ""test type""
                  }, 
                  ""Position"" : 
                  {
                    ""X"" : 5, 
                    ""Y"" : 7
                  }
                }
              ]
            }";

            var ser = new JavaScriptSerializer();
            ser.Deserialize<Foo>(json);
        }
    }

    public class Foo
    {
        public Foo() { Objects = new List<SubObject>(); }
        public string DisplayFieldName { get; set; }
        public NameTypePair FieldAliases { get; set; }
        public PositionType PositionType { get; set; }
        public Ref Reference { get; set; }
        public List<SubObject> Objects { get; set; }
    }

    public class NameTypePair
    {
        public string ObjectName { get; set; }
        public string ObjectType { get; set; }
    }

    public enum PositionType { None, Point }
    public class Ref
    {
        public int Id { get; set; }
    }

    public class SubObject
    {
        public NameTypePair Attributes { get; set; }
        public Position Position { get; set; }
    }

    public class Position
    {
        public int X { get; set; }
        public int Y { get; set; }
    }
}

How about this?

List<string> monValues = Application["mondayValues"] as List<string>;
int sum = monValues.ConvertAll(Convert.ToInt32).Sum();

student_user = User.objects.get(id=user_id)
available_subjects = Subject.objects.exclude(subject_grade__student__user=student_user) # My ans
enrolled_subjects = SubjectGrade.objects.filter(student__user=student_user)
context.update({'available_subjects': available_subjects, 'student_user': student_user, 
                'request':request, 'enrolled_subjects': enrolled_subjects})

In my application above, i assume that once a student is enrolled, a subject SubjectGrade instance will be created that contains the subject enrolled and the student himself/herself.

Subject and Student User model is a Foreign Key to the SubjectGrade Model.

In "available_subjects", i excluded all the subjects that are already enrolled by the current student_user by checking all subjectgrade instance that has "student" attribute as the current student_user

PS. Apologies in Advance if you can't still understand because of my explanation. This is the best explanation i Can Provide. Thank you so much

mylist=['abc','def','ghi','abc']

pattern=re.compile(r'abc') 

pattern.findall(mylist)

I believe you would have to "git revert" back to that commit and then push it. Or you could cherry-pick a commit into a new branch, and push that to the branch on the remote repository. Something like:

git branch onecommit
git checkout onecommit
git cherry-pick 7300a6130d9447e18a931e898b64eefedea19544 # From the other branch
git push origin {branch}

I restarted my computer and then opened the IDE again and it worked while none of the above did.

Maybe you have to do the things above as well, but make sure to restart the computer too.

Umbrello does that too. in the menu go to Code -> import project and then point to the root deirectory of your project. then it reverses the code for ya...

Find with a specific date:

db.getCollection('CollectionName').find({"DepartureDate" : new ISODate("2019-06-21T00:00:00.000Z")})

Find with greater gte or little lt :

db.getCollection('CollectionName').find({"DepartureDate" : { $gte : new ISODate("2019-06-11T00:00:00.000Z") }})

Find by range:

db.getCollection('CollectionName').find({ 
    "DepartureDate": { 
        $lt: new Date(), 
        $gte: new Date(new Date().setDate(new Date().getDate()-15))
      } 
    })

If a method only accesses local variables, it's thread safe. Is that it?

Absolultely not. You can write a program with only a single local variable accessed from a single thread that is nevertheless not threadsafe:

https://stackoverflow.com/a/8883117/88656

Does that apply for static methods as well?

Absolutely not.

One answer, provided by @Cybis, was: "Local variables cannot be shared among threads because each thread gets its own stack."

Absolutely not. The distinguishing characteristic of a local variable is that it is only visible from within the local scope, not that it is allocated on the temporary pool. It is perfectly legal and possible to access the same local variable from two different threads. You can do so by using anonymous methods, lambdas, iterator blocks or async methods.

Is that the case for static methods as well?

Absolutely not.

If a method is passed a reference object, does that break thread safety?

Maybe.

I've done some research, and there is a lot out there about certain cases, but I was hoping to be able to define, by using just a few rules, guidelines to follow to make sure a method is thread safe.

You are going to have to learn to live with disappointment. This is a very difficult subject.

So, I guess my ultimate question is: "Is there a short list of rules that define a thread-safe method?

Nope. As you saw from my example earlier an empty method can be non-thread-safe. You might as well ask "is there a short list of rules that ensures a method is correct". No, there is not. Thread safety is nothing more than an extremely complicated kind of correctness.

Moreover, the fact that you are asking the question indicates your fundamental misunderstanding about thread safety. Thread safety is a global, not a local property of a program. The reason why it is so hard to get right is because you must have a complete knowledge of the threading behaviour of the entire program in order to ensure its safety.

Again, look at my example: every method is trivial. It is the way that the methods interact with each other at a "global" level that makes the program deadlock. You can't look at every method and check it off as "safe" and then expect that the whole program is safe, any more than you can conclude that because your house is made of 100% non-hollow bricks that the house is also non-hollow. The hollowness of a house is a global property of the whole thing, not an aggregate of the properties of its parts.

For the UPDATE

Use:

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

For the INSERT

Use:

INSERT INTO table1 (col1, col2) 
SELECT col1, col2 
  FROM othertable

You don't need the VALUES syntax if you are using a SELECT to populate the INSERT values.

Given the C99 standard (namely, the N1256 draft), the rules depend on the function kind: fprintf (printf, sprintf, ...) or scanf.

Here are relevant parts extracted:

Foreword

This second edition cancels and replaces the first edition, ISO/IEC 9899:1990, as amended and corrected by ISO/IEC 9899/COR1:1994, ISO/IEC 9899/AMD1:1995, and ISO/IEC 9899/COR2:1996. Major changes from the previous edition include:

• %lf conversion specifier allowed in printf

7.19.6.1 The fprintf function

7 The length modifiers and their meanings are:

l (ell) Specifies that (...) has no effect on a following a, A, e, E, f, F, g, or G conversion specifier.

L Specifies that a following a, A, e, E, f, F, g, or G conversion specifier applies to a long double argument.

The same rules specified for fprintf apply for printf, sprintf and similar functions.

7.19.6.2 The fscanf function

11 The length modifiers and their meanings are:

l (ell) Specifies that (...) that a following a, A, e, E, f, F, g, or G conversion specifier applies to an argument with type pointer to double;

L Specifies that a following a, A, e, E, f, F, g, or G conversion specifier applies to an argument with type pointer to long double.

12 The conversion specifiers and their meanings are: a,e,f,g Matches an optionally signed floating-point number, (...)

14 The conversion specifiers A, E, F, G, and X are also valid and behave the same as, respectively, a, e, f, g, and x.

The long story short, for fprintf the following specifiers and corresponding types are specified:

• %f -> double
• %Lf -> long double.

and for fscanf it is:

• %f -> float
• %lf -> double
• %Lf -> long double.

VanillaJS === JavaScript i.e.VanillaJS is native JavaScript

Why, Vanilla says it all!!!

Computer software, and sometimes also other computing-related systems like computer hardware or algorithms, are called vanilla when not customized from their original form, meaning that they are used without any customization or updates applied to them (Refer this article). So Vanilla often refers to pure or plain.

In the English language Vanilla has a similar meaning, In information technology, vanilla (pronounced vah-NIHL-uh ) is an adjective meaning plain or basic. Or having no special or extra features, ordinary or standard.

So why name it VanillaJS? As the accepted answer says some bosses want to work with a framework (because it's more organized and flexible and do all the things we want??) but simply JavaScript will do the job. Yet you need to add a framework somewhere. Use VanillaJS...

Is it a Joke? YES

Want some fun? Where can you find it, http://vanilla-js.com/ Download and see for yourself!!! It's 0 bytes uncompressed, 25 bytes gzipped :D

Found this pun on internet regarding JS frameworks (Not to condemn the existing JS frameworks though, they'll make life really easy :)),

My solution is to pass the query result $rs and get a assoc array of the casted data as the return:

function cast_query_results($rs) {
    $fields = mysqli_fetch_fields($rs);
    $data = array();
    $types = array();
    foreach($fields as $field) {
        switch($field->type) {
            case 3:
                $types[$field->name] = 'int';
                break;
            case 4:
                $types[$field->name] = 'float';
                break;
            default:
                $types[$field->name] = 'string';
                break;
        }
    }
    while($row=mysqli_fetch_assoc($rs)) array_push($data,$row);
    for($i=0;$i<count($data);$i++) {
        foreach($types as $name => $type) {
            settype($data[$i][$name], $type);
        }
    }
    return $data;
}

Example usage:

$dbconn = mysqli_connect('localhost','user','passwd','tablename');
$rs = mysqli_query($dbconn, "SELECT * FROM Matches");
$matches = cast_query_results($rs);
// $matches is now a assoc array of rows properly casted to ints/floats/strings

I was also wanted to upload stuff to a Server and it was a Spring application i finally discovered that I needed to acctually set an content type for it to interpret it as a file. Just like this:

...
MultipartFormDataContent form = new MultipartFormDataContent();
var fileStream = new FileStream(uniqueTempPathInProject, FileMode.Open);
var streamContent = new StreamContent(fileStream);
streamContent.Headers.ContentType=new MediaTypeHeaderValue("application/zip");
form.Add(streamContent, "file",fileName);
...

Here's some swift-code for you to set the line spacing programmatically

let label = UILabel()

let attributedText = NSMutableAttributedString(string: "Your string")
let paragraphStyle = NSMutableParagraphStyle()

//SET THIS:
paragraphStyle.lineSpacing = 4
//OR SET THIS:
paragraphStyle.lineHeightMultiple = 4

//Or set both :)

let range = NSMakeRange(0, attributedText.length)
attributedText.addAttributes([NSParagraphStyleAttributeName : paragraphStyle], range: range)
label.attributedText = attributedText

From the official document:

"Visual Studio Code is unable to watch for file changes in this large workspace" (error ENOSPC)

When you see this notification, it indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. The current limit can be viewed by running:

cat /proc/sys/fs/inotify/max_user_watches

The limit can be increased to its maximum by editing

/etc/sysctl.conf

and adding this line to the end of the file:

fs.inotify.max_user_watches=524288

The new value can then be loaded in by running

sudo sysctl -p

Note that Arch Linux works a little differently, See Increasing the amount of inotify watchers for details.

While 524,288 is the maximum number of files that can be watched, if you're in an environment that is particularly memory constrained, you may wish to lower the number. Each file watch takes up 540 bytes (32-bit) or ~1kB (64-bit), so assuming that all 524,288 watches are consumed, that results in an upper bound of around 256MB (32-bit) or 512MB (64-bit).

Another option

is to exclude specific workspace directories from the VS Code file watcher with the files.watcherExclude setting. The default for files.watcherExclude excludes node_modules and some folders under .git, but you can add other directories that you don't want VS Code to track.

"files.watcherExclude": {
    "**/.git/objects/**": true,
    "**/.git/subtree-cache/**": true,
    "**/node_modules/*/**": true
  }

The idmax of the DataFrame returns the label index of the row with the maximum value and the behavior of argmax depends on version of pandas (right now it returns a warning). If you want to use the positional index, you can do the following:

max_row = df['A'].values.argmax()

or

import numpy as np
max_row = np.argmax(df['A'].values)

Note that if you use np.argmax(df['A']) behaves the same as df['A'].argmax().

Run the following to get the right NVIDIA driver :

sudo ubuntu-drivers devices

Then pick the right and run:

sudo apt install <version>

Looks like you are using maven (src/main/java). In this case put the applicationContext.xml file in the src/main/resources directory. It will be copied in the classpath directory and you should be able to access it with

@ContextConfiguration("/applicationContext.xml")

From the Spring-Documentation: A plain path, for example "context.xml", will be treated as a classpath resource from the same package in which the test class is defined. A path starting with a slash is treated as a fully qualified classpath location, for example "/org/example/config.xml".

So it's important that you add the slash when referencing the file in the root directory of the classpath.

If you work with the absolute file path you have to use 'file:C:...' (if I understand the documentation correctly).

Try with this:

          $.ajax({
              type: 'POST',
              url: URL,
              defaultHeaders: {
                  'Content-Type': 'application/json',
                  "Access-Control-Allow-Origin": "*",
                  'Accept': 'application/json'
               },

              data: obj,
              dataType: 'json',
              success: function (response) {
            //    BindTableData();
                console.log("success ");
                alert(response);
              },
              error: function (xhr) {
                console.log("error ");
                console.log(xhr);
              }
          });

You can also use setShowSoftInputOnFocus(boolean) directly on API 21+ or through reflection on API 14+:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    editText.setShowSoftInputOnFocus(false);
} else {
    try {
        final Method method = EditText.class.getMethod(
                "setShowSoftInputOnFocus"
                , new Class[]{boolean.class});
        method.setAccessible(true);
        method.invoke(editText, false);
    } catch (Exception e) {
        // ignore
    }
}

Edit: Unfortunately, as of PHP 8.0, the answer is not "No, not anymore". This RFC was not accepted as I hoped, proposing to change T_PAAMAYIM_NEKUDOTAYIM to T_DOUBLE_COLON; but it was declined.

Note: I keep this answer for historical purposes. Actually, because of the creation of the RFC and the votes ratio at some point, I created this answer. Also, I keep this for hoping it to be accepted in the near future.

For traversing through a 2D array, I think the following for loop can be used.

        for(int a[]: twoDm)
        {
            System.out.println(Arrays.toString(a));
        }
if you don't want the commas you can string replace
if you want this to be performant you should loop through a[] and then print it.

I know this is old but since no one mentioned about using awk:

    firstString="I love Suzi and Marry"
    echo $firstString | awk '{gsub("Suzi","Sara"); print}'

Regular expressions actually aren't part of ANSI C. It sounds like you might be talking about the POSIX regular expression library, which comes with most (all?) *nixes. Here's an example of using POSIX regexes in C (based on this):

#include <regex.h>        
regex_t regex;
int reti;
char msgbuf[100];

/* Compile regular expression */
reti = regcomp(&regex, "^a[[:alnum:]]", 0);
if (reti) {
    fprintf(stderr, "Could not compile regex\n");
    exit(1);
}

/* Execute regular expression */
reti = regexec(&regex, "abc", 0, NULL, 0);
if (!reti) {
    puts("Match");
}
else if (reti == REG_NOMATCH) {
    puts("No match");
}
else {
    regerror(reti, &regex, msgbuf, sizeof(msgbuf));
    fprintf(stderr, "Regex match failed: %s\n", msgbuf);
    exit(1);
}

/* Free memory allocated to the pattern buffer by regcomp() */
regfree(&regex);

Alternatively, you may want to check out PCRE, a library for Perl-compatible regular expressions in C. The Perl syntax is pretty much that same syntax used in Java, Python, and a number of other languages. The POSIX syntax is the syntax used by grep, sed, vi, etc.

For the following HTML document:

<html>
  <body>
    <a href="http://www.example.com">Example</a> 
    <a href="http://www.stackoverflow.com">SO</a> 
  </body>
</html>

The xpath query /html/body//a/@href (or simply //a/@href) will return:

    http://www.example.com
    http://www.stackoverflow.com

To select a specific instance use /html/body//a[N]/@href,

    $ /html/body//a[2]/@href
    http://www.stackoverflow.com

To test for strings contained in the attribute and return the attribute itself place the check on the tag not on the attribute:

    $ /html/body//a[contains(@href,'example')]/@href
    http://www.example.com

Mixing the two:

    $ /html/body//a[contains(@href,'com')][2]/@href
    http://www.stackoverflow.com

Edit the application tag in manifest file.

 <application
    android:icon="@drawable/app_icon"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >

Change the label attribute and give the latest name over there.

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;   
if (!isNaN(top)) {
$("#app_scroler").click(function () {   
$('html, body').animate({
            scrollTop: top
        }, 100);
    });
}

if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;

This provides you the code example on sorting map. Basically this is what they provide:

var keys []int
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark1-8      2863149           374 ns/op         152 B/op          5 allocs/op

and this is what I would suggest using instead:

keys := make([]int, 0, len(myMap))
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark2-8      5320446           230 ns/op          80 B/op          2 allocs/op

Eight different ways to clear the plan cache

1. Remove all elements from the plan cache for the entire instance

DBCC FREEPROCCACHE;

Use this to clear the plan cache carefully. Freeing the plan cache causes, for example, a stored procedure to be recompiled instead of reused from the cache. This can cause a sudden, temporary decrease in query performance.

2. Flush the plan cache for the entire instance and suppress the regular completion message

"DBCC execution completed. If DBCC printed error messages, contact your system administrator."

DBCC FREEPROCCACHE WITH NO_INFOMSGS;

3. Flush the ad hoc and prepared plan cache for the entire instance

DBCC FREESYSTEMCACHE ('SQL Plans');

4. Flush the ad hoc and prepared plan cache for one resource pool

DBCC FREESYSTEMCACHE ('SQL Plans', 'LimitedIOPool');

5. Flush the entire plan cache for one resource pool

DBCC FREEPROCCACHE ('LimitedIOPool');

6. Remove all elements from the plan cache for one database (does not work in SQL Azure)

-- Get DBID from one database name first
DECLARE @intDBID INT;

In addition to the excellent answers above, let me offer you a link to the following article (by Patrick Thomson) which explains monads by relating the concept to the JavaScript library jQuery (and its way of using "method chaining" to manipulate the DOM): jQuery is a Monad

The jQuery documentation itself doesn't refer to the term "monad" but talks about the "builder pattern" which is probably more familiar. This doesn't change the fact that you have a proper monad there maybe without even realizing it.

You can use a node.js extension to provide bindings for your C++ code. Here is one tutorial that covers that:

http://syskall.com/how-to-write-your-own-native-nodejs-extension

Same as the answer by Dmitry Yudakov, but without an intermediate file, using process substitution:

svn commit --targets <(echo "MyFile1.txt\nMyFile2.txt\n")

For someone who want to use onchange event directly on file input, set onchange="somefunction(), example code from the link:

<html>
<body>
    <script language="JavaScript">
    function inform(){
        document.form1.msg.value = "Filename has been changed";
    }
    </script>
    <form name="form1">
    Please choose a file.
    <input type="file" name="uploadbox" size="35" onChange='inform()'>
    <br><br>
    Message:
    <input type="text" name="msg" size="40">
    </form>
</body>
</html>

Well, I've got no problem here :

df <- data.frame(v=1:5, x=sample(LETTERS[1:5],5))
df

#   v x
# 1 1 D
# 2 2 A
# 3 3 B
# 4 4 C
# 5 5 E

df <- df[order(df$x),]
df

#   v x
# 2 2 A
# 3 3 B
# 4 4 C
# 1 1 D
# 5 5 E

One reason to always include a character set specification on every page containing text is to avoid cross site scripting vulnerabilities. In most cases the UTF-8 character set is the best choice for text, including HTML pages.

Use Object#toString().

String string = map.toString();

That's after all also what System.out.println(object) does under the hoods. The format for maps is described in AbstractMap#toString().

Returns a string representation of this map. The string representation consists of a list of key-value mappings in the order returned by the map's entrySet view's iterator, enclosed in braces ("{}"). Adjacent mappings are separated by the characters ", " (comma and space). Each key-value mapping is rendered as the key followed by an equals sign ("=") followed by the associated value. Keys and values are converted to strings as by String.valueOf(Object).

The way you are doing it is indeed the recommended one (for Python 2.x).

The issue of whether the class is passed explicitly to super is a matter of style rather than functionality. Passing the class to super fits in with Python's philosophy of "explicit is better than implicit".

Change detection is not triggered when you change a property of an object (including nested object). One solution would be to reassign a new object reference using 'lodash' clone() function.

import * as _ from 'lodash';

this.foo = _.clone(this.foo);

should call the function properly; like- Fibonacci:input

C# knows two terms, delegate and event. Let's start with the first one.

Delegate

A delegate is a reference to a method. Just like you can create a reference to an instance:

MyClass instance = myFactory.GetInstance();

You can use a delegate to create an reference to a method:

Action myMethod = myFactory.GetInstance;

Now that you have this reference to a method, you can call the method via the reference:

MyClass instance = myMethod();

But why would you? You can also just call myFactory.GetInstance() directly. In this case you can. However, there are many cases to think about where you don't want the rest of the application to have knowledge of myFactory or to call myFactory.GetInstance() directly.

An obvious one is if you want to be able to replace myFactory.GetInstance() into myOfflineFakeFactory.GetInstance() from one central place (aka factory method pattern).

Factory method pattern

So, if you have a TheOtherClass class and it needs to use the myFactory.GetInstance(), this is how the code will look like without delegates (you'll need to let TheOtherClass know about the type of your myFactory):

TheOtherClass toc;
//...
toc.SetFactory(myFactory);


class TheOtherClass
{
   public void SetFactory(MyFactory factory)
   {
      // set here
   }

}

If you'd use delegates, you don't have to expose the type of my factory:

TheOtherClass toc;
//...
Action factoryMethod = myFactory.GetInstance;
toc.SetFactoryMethod(factoryMethod);


class TheOtherClass
{
   public void SetFactoryMethod(Action factoryMethod)
   {
      // set here
   }

}

Thus, you can give a delegate to some other class to use, without exposing your type to them. The only thing you're exposing is the signature of your method (how many parameters you have and such).

"Signature of my method", where did I hear that before? O yes, interfaces!!! interfaces describe the signature of a whole class. Think of delegates as describing the signature of only one method!

Another large difference between an interface and a delegate is that when you're writing your class, you don't have to say to C# "this method implements that type of delegate". With interfaces, you do need to say "this class implements that type of an interface".

Further, a delegate reference can (with some restrictions, see below) reference multiple methods (called MulticastDelegate). This means that when you call the delegate, multiple explicitly-attached methods will be executed. An object reference can always only reference to one object.

The restrictions for a MulticastDelegate are that the (method/delegate) signature should not have any return value (void) and the keywords out and ref is not used in the signature. Obviously, you can't call two methods that return a number and expect them to return the same number. Once the signature complies, the delegate is automatically a MulticastDelegate.

Event

Events are just properties (like the get;set; properties to instance fields) which expose subscription to the delegate from other objects. These properties, however, don't support get;set;. Instead, they support add; remove;

So you can have:

    Action myField;

    public event Action MyProperty
    {
        add { myField += value; }
        remove { myField -= value; }
    }

Usage in UI (WinForms,WPF,UWP So on)

So, now we know that a delegate is a reference to a method and that we can have an event to let the world know that they can give us their methods to be referenced from our delegate, and we are a UI button, then: we can ask anyone who is interested in whether I was clicked, to register their method with us (via the event we exposed). We can use all those methods that were given to us and reference them by our delegate. And then, we'll wait and wait.... until a user comes and clicks on that button, then we'll have enough reason to invoke the delegate. And because the delegate references all those methods given to us, all those methods will be invoked. We don't know what those methods do, nor we know which class implements those methods. All we do care about is that someone was interested in us being clicked, and gave us a reference to a method that complied with our desired signature.

Java

Languages like Java don't have delegates. They use interfaces instead. The way they do that is to ask anyone who is interested in 'us being clicked', to implement a certain interface (with a certain method we can call), then give us the whole instance that implements the interface. We keep a list of all objects implementing this interface and can call their 'certain method we can call' whenever we get clicked.

return "default" if x is None else x

try the above.

"Why aren't you using something else?"

Sorry, someone had to say it :)

c(df$x, df$y)
# returns: 26 21 20 34 29 28

if the particular order is important then:

M = as.matrix(df)
c(m[1,], c[2,], c[3,])
# returns 26 34 21 29 20 28 

Or more generally:

m = as.matrix(df)
q = c()
for (i in seq(1:nrow(m))){
  q = c(q, m[i,])
}

# returns 26 34 21 29 20 28

Originally javax was intended to be for extensions, and sometimes things would be promoted out of javax into java.

One issue was Netscape (and probably IE) limiting classes that could be in the java package.

When Swing was set to "graduate" to java from javax there was sort of a mini-blow up because people realized that they would have to modify all of their imports. Given that backwards compatibility is one of the primary goals of Java they changed their mind.

At that point in time, at least for the community (maybe not for Sun) the whole point of javax was lost. So now we have some things in javax that probably should be in java... but aside from the people that chose the package names I don't know if anyone can figure out what the rationale is on a case-by-case basis.

If I understand you correctly, you want to do something like this:

In such case, it should be just enough to use:

<item name="android:colorButtonNormal">#2196f3</item>

Or for API less than 21:

<item name="colorButtonNormal">#2196f3</item>

Animated variant is here.

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.
