Try:

range(x1,x2+1)  

That is a list in Python 2.x and behaves mostly like a list in Python 3.x. If you are running Python 3 and need a list that you can modify, then use:

list(range(x1,x2+1))

you need to use getResources() method, try to use following code

View someView = findViewById(R.id.screen);
View root = someView.getRootView();
root.setBackgroundColor(getResources().getColor(color.white)); 

Edit::

getResources.getColor() is deprecated so, use like below

 root.setBackgroundColor(ContextCompat.getColor(this, R.color.white)); 

npm i -D @angular/material @angular/cdk @angular/animations

Fixing must override a super class method error is not difficult, You just need to change Java source version to 1.6 because from Java 1.6 @Override annotation can be used along with interface method. In order to change source version to 1.6 follow below steps :

1. Select Project , Right click , Properties
2. Select Java Compiler and check the check box "Enable project specific settings"
3. Now make Compiler compliance level to 1.6
4. Apply changes

Here is what I did on my ubuntu 16.04 machine

sudo apt-get update
sudo wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
sudo mv path/where/you/downloaded/phantomjs  /usr/bin

and finally when I do

phantomjs -v

I get 2.1.1

After going through every answer of this thread. I think this is the best solution for installing and running phantomjs in ubuntu.

I'm surprised that no one has mentioned prepared statements. Unless you are using SQL on its own and not within any other language, then I would think that prepared statements wrapped in a transaction would be the most efficient way of inserting multiple rows.

VARCHAR means that it's a variable-length character, so it's only going to take as much space as is necessary. But if you knew something about the underlying structure, it may make sense to restrict VARCHAR to some maximum amount.

For instance, if you were storing comments from the user, you may limit the comment field to only 4000 characters; if so, it doesn't really make any sense to make the sql table have a field that's larger than VARCHAR(4000).

I got the same error and couldn't solve it.

Then I noticed 3 extra files in one of my directories.

The files were named:

config, HEAD, description

I deleted the files, and the error didn't appear.

config contained:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = true

HEAD contained:

ref: refs/heads/master

description contained:

Unnamed repository; edit this file 'description' to name the repository.

I won't expand the acronym yet again... but I will add some nuance to the other definition: you can store any data in a blob regardless of other byte interpretations they may have. Text can be stored in a blob, but you would be better off with a CLOB if you have that option.

There should be no differences between BLOBS across databases in the sense that after you have saved and retrieved the data it is unchanged.... how each database achieves that is a blackbox and thankfully almost without exception irrelevant. The manner of interacting with BLOBS, however can be very different since there are no specifications in SQL standards (or standards in the specifications?) for it. Usually you will have to invoke procedures/functions to save retrieve them, and limiting any query based on the contents of a BLOB is nearly impossible if not prohibited.

Among the other stuff enumerated as binary data, you can also store binary representations of text -> character codes with a given encoding... without actually knowing or specifying the encoding used.

BLOBS are the lowest common denominators of storage formats.

You could use a Common Table Expression to create the SUM first, join it to the table, and then use the WHEN to to get the value from the CTE or the original table as necessary.

WITH PercentageOfTotal (Id, Percentage) 
AS 
(
    SELECT Id, (cnt / SUM(AreaId)) FROM dbo.MyTable GROUP BY Id
)
SELECT 
    CASE
        WHEN o.TotalType = 'Average' THEN r.avgscore
        WHEN o.TotalType = 'PercentOfTot' THEN pt.Percentage
        ELSE o.cnt
    END AS [displayscore]
FROM PercentageOfTotal pt
    JOIN dbo.MyTable t ON pt.Id = t.Id

EDIT: This doesn't work on tuples with duplicate entries yet!!

Based on Pooya's idea:

If you are planning on doing this often (which you shouldn't since tuples are inmutable for a reason) you should do something like this:

def modTupByIndex(tup, index, ins):
    return tuple(tup[0:index]) + (ins,) + tuple(tup[index+1:])

print modTupByIndex((1,2,3),2,"a")

Or based on Jon's idea:

def modTupByIndex(tup, index, ins):
    lst = list(tup)
    lst[index] = ins
    return tuple(lst)

print modTupByIndex((1,2,3),1,"a")

webkit2html works on Mac OS X and Linux, is quite simple to install and to use. See this tutorial.

For Windows, you can go with CutyCapt, which has similar functionality.

Use the following query:

SELECT E.I_EmpID AS EMPID,
       E.I_EMPCODE AS EMPCODE,
       E.I_EmpName AS EMPNAME,
       REPLACE(TO_CHAR(A.I_REQDATE, 'DD-Mon-YYYY'), ' ', '') AS FROMDATE,
       REPLACE(TO_CHAR(A.I_ENDDATE, 'DD-Mon-YYYY'), ' ', '') AS TODATE,
       TO_CHAR(NOD) AS NOD,
       DECODE(A.I_DURATION,
              'FD',
              'FullDay',
              'FN',
              'ForeNoon',
              'AN',
              'AfterNoon') AS DURATION,
       L.I_LeaveType AS LEAVETYPE,
       REPLACE(TO_CHAR((SELECT max(C.I_WORKDATE)
                         FROM T_COMPENSATION C
                        WHERE C.I_COMPENSATEDDATE = A.I_REQDATE
                          AND C.I_EMPID = A.I_EMPID),
                       'DD-Mon-YYYY'),
               ' ',
               '') AS WORKDATE,
       A.I_REASON AS REASON,
       AP.I_REJECTREASON AS REJECTREASON
  FROM T_LEAVEAPPLY A
 INNER JOIN T_EMPLOYEE_MS E
    ON A.I_EMPID = E.I_EmpID
   AND UPPER(E.I_IsActive) = 'YES'
   AND A.I_STATUS = '1'
 INNER JOIN T_LeaveType_MS L
    ON A.I_LEAVETYPEID = L.I_LEAVETYPEID
  LEFT OUTER JOIN T_APPROVAL AP
    ON A.I_REQDATE = AP.I_REQDATE
   AND A.I_EMPID = AP.I_EMPID
   AND AP.I_APPROVALSTATUS = '1'
 WHERE E.I_EMPID <> '22'
 ORDER BY A.I_REQDATE DESC

The trick is to force the inner query return only one record by adding an aggregate function (I have used max() here). This will work perfectly as far as the query is concerned, but, honestly, OP should investigate why the inner query is returning multiple records by examining the data. Are these multiple records really relevant business wise?

I managed to fix this by adding:

android:layout_marginTop="?android:attr/actionBarSize"

to the FrameLayout like so:

 <FrameLayout
        android:id="@+id/content"
        android:layout_marginTop="?android:attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
       />

To unzip all files in a directory just type this cmd in terminal:

unzip '*.zip'

Run vim from the terminal. For the basics, you're advised to run the command vimtutor.

# On your terminal command line:
$ vim

If you have a specific file to edit, pass it as an argument.

$ vim yourfile.cpp

Likewise, launch the tutorial

$ vimtutor

For MacOS

Sometimes the ng command does not get established as a link in /usr/local/bin. I fixed the problem by adding it manually:

ln -s /usr/local/Cellar/node/10.10.0/lib/node_modules/angular-cli/bin/ng /usr/local/bin/ng

$data['cat'] = 'wagon';

That's all you need to add the key and value to the array.

Executing git remote update works for me.

cd /d c:\
git clone C:\folder1 folder2

From the documentation for git clone:

For local repositories, also supported by git natively, the following syntaxes may be used:

/path/to/repo.git/

file:///path/to/repo.git/

These two syntaxes are mostly equivalent, except the former implies --local option.

For me, I had //= require jquery after //= require bootstrap. Once I moved jquery before bootstrap, everything worked.

In Swift 3.0+, UIBarButtonItem programmatically set up as follows:

   override func viewDidLoad() {
        super.viewDidLoad()
        let testUIBarButtonItem = UIBarButtonItem(image: UIImage(named: "test.png"), style: .plain, target: self, action: #selector(self.clickButton))
        self.navigationItem.rightBarButtonItem  = testUIBarButtonItem
    }

   @objc func clickButton(){
            print("button click")
     }

Below is a very simple code to demonstrate the requirement of volatile for variable which is used to control the Thread execution from other thread (this is one scenario where volatile is required).

// Code to prove importance of 'volatile' when state of one thread is being mutated from another thread.
// Try running this class with and without 'volatile' for 'state' property of Task class.
public class VolatileTest {
    public static void main(String[] a) throws Exception {
        Task task = new Task();
        new Thread(task).start();

        Thread.sleep(500);
        long stoppedOn = System.nanoTime();

        task.stop(); // -----> do this to stop the thread

        System.out.println("Stopping on: " + stoppedOn);
    }
}

class Task implements Runnable {
    // Try running with and without 'volatile' here
    private volatile boolean state = true;
    private int i = 0;

    public void stop() {
        state = false;
    } 

    @Override
    public void run() {
        while(state) {
            i++;
        }
        System.out.println(i + "> Stopped on: " + System.nanoTime());
    }
}

When volatile is not used: you'll never see 'Stopped on: xxx' message even after 'Stopping on: xxx', and the program continues to run.

Stopping on: 1895303906650500

When volatile used: you'll see the 'Stopped on: xxx' immediately.

Stopping on: 1895285647980000
324565439> Stopped on: 1895285648087300

To answer your question: no, it's not possible to have multiple versions of IE (if that is what you meant) installed in a 'normal' way (i.e. not a hack, a sandbox or a VM etc). It's perfectly ok to have multiple browsers of different types installed on the same machine, such as IE8, Firefox 3 and Chrome all at once.

SandboxIE should allow you to install multiple versions of IE side-by-side (as well as other software), and this is less hassle than going down the virtual machine route.

However, from a QA point of view I'd strongly recommend installing different versions on different machines as the best option from a testing point of view. This will give you the most realistic testing environment. If you don't have the hardware for that, then virtual machines are the next best option as mentioned in some of the other answers.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

An even shorter version:

require 'open-uri'
download = open('http://example.com/image.png')
IO.copy_stream(download, '~/image.png')

To keep the same filename:

IO.copy_stream(download, "~/#{download.base_uri.to_s.split('/')[-1]}")

Unfortunately the answers given so far (including the most voted) are either "just" common sense, plain wrong or confusing at best. None of crucial keywords¹ pop up!

I wrote 3 answers:

1. This explanation (start here).
2. Concrete answers to OP’s questions.
3. Improved detailed HTML.

To understand the role of the html elements discussed here you have to know that some of them section the document. Each and every html document can be sectioned according to the HTML5 outline algorithm for the purpose of creating an outline—⁠or⁠—table of contents (TOC). The outline is not generally visible (these days), but authors should use html in such a way that the resulting outline reflects their intentions.

You can create sections with exactly these elements and nothing else:

• creating (explicit) subsections
  • <section> sections
  • <article> sections
  • <nav> sections
  • <aside> sections
• creating sibling sections or subsections
  • sections of unspecified type with <h*>² (not all do this, see below)
• to level up close the current explicit (sub)section

Sections can be named:

• <h*> created sections name themselves
• <section|article|nav|aside> sections will be named by the first <h*> if there is one
  • these <h*> are the only ones which don’t create sections themselves

There is one more thing to sections: the following contexts (i.e. elements) create "outline boundaries". Whatever sections they contain is private to them:

• the document itself with <body>
• table cells with <td>
• <blockquote>
• <details>, <dialog>, <fieldset>, and <figure>
• nothing else

example HTML
<body> <h3>if you want siblings at top level...</h3> <h3>...you have to use untyped sections with <h*>...</h3> <article> <h1>...as any other section will descent</h1> </article> <nav> <ul> <li><a href=...>...</a></li> </ul> </nav> </body> has this outline
1. if you want siblings at top level... 2. ...you have to use untyped sections with <h*>... 2.1. ...as any other section will descent 2.2. (unnamed navigation)

This raises two questions:

What is the difference between <article> and <section>?

• both can:
  • be nested in each other
  • take a different notion in a different context or nesting level
• <section>s are like book chapters
  • they usually have siblings (maybe in a different document?)
  • together they have something in common, like chapters in a book
• one author, one <article>, at least on the lowest level
  • standard example: a single blog comment
  • a blog entry itself is also a good example
  • a blog entry <article> and its comment <article>s could also be wrapped with an <article>
  • it’s some "complete" thing, not a part in a series of similar
• <section>s in an <article> are like chapters in a book
• <article>s in a <section> are like poems in a volume (within a series)

How do <header>, <footer> and <main> fit in?

• they have zero influence on sectioning
• <header> and <footer>
  • they allow you to mark zones of each and every section
  • even within a section you can have them several times
  • to differentiate from the main part in this section
  • limited only by the author’s taste
  • <header>
    • may mark the title/name of this section
    • may contain a logo for this section
    • has no need to be at the top or upper part of the section
  • <footer>
    • may mark the credits/author of this section
    • can come at the top of the section
    • can even be above a <header>
• <main>
  • only allowed once
  • marks the main part of the top level section (i.e. the document, <body> that is)
  • subsections themselves have no markup for their main part
  • <main> can even “hide” in some subsections of the document, while document’s <header> and <footer> can’t (that markup would mark header/footer of that subsection then)
    • but it is not allowed in <article> sections³
  • helps to distinguish “the real thing” from document’s non-header, non-footer, non-main content, if that makes sense in your case...
    

^{1 to mind comes: outline, algorithm, implicit sectioning
2 I use <h*> as shorthand for <h1>, <h2>, <h3>, <h4>, <h5> and <h6>
3 neither is <main> allowed in <aside> or <nav>, but that is of no surprise. – In effect: <main> can only hide in (nested) descending <section> sections or appear at top level, namely <body>}

With the help of raincoat's code on GitHub, I managed to get a running version accessing the clipboard with plain JavaScript.

function TrelloClipboard() {
    var me = this;

    var utils = {
        nodeName: function (node, name) {
            return !!(node.nodeName.toLowerCase() === name)
        }
    }
    var textareaId = 'simulate-trello-clipboard',
        containerId = textareaId + '-container',
        container, textarea

    var createTextarea = function () {
        container = document.querySelector('#' + containerId)
        if (!container) {
            container = document.createElement('div')
            container.id = containerId
            container.setAttribute('style', [, 'position: fixed;', 'left: 0px;', 'top: 0px;', 'width: 0px;', 'height: 0px;', 'z-index: 100;', 'opacity: 0;'].join(''))
            document.body.appendChild(container)
        }
        container.style.display = 'block'
        textarea = document.createElement('textarea')
        textarea.setAttribute('style', [, 'width: 1px;', 'height: 1px;', 'padding: 0px;'].join(''))
        textarea.id = textareaId
        container.innerHTML = ''
        container.appendChild(textarea)

        textarea.appendChild(document.createTextNode(me.value))
        textarea.focus()
        textarea.select()
    }

    var keyDownMonitor = function (e) {
        var code = e.keyCode || e.which;
        if (!(e.ctrlKey || e.metaKey)) {
            return
        }
        var target = e.target
        if (utils.nodeName(target, 'textarea') || utils.nodeName(target, 'input')) {
            return
        }
        if (window.getSelection && window.getSelection() && window.getSelection().toString()) {
            return
        }
        if (document.selection && document.selection.createRange().text) {
            return
        }
        setTimeout(createTextarea, 0)
    }

    var keyUpMonitor = function (e) {
        var code = e.keyCode || e.which;
        if (e.target.id !== textareaId || code !== 67) {
            return
        }
        container.style.display = 'none'
    }

    document.addEventListener('keydown', keyDownMonitor)
    document.addEventListener('keyup', keyUpMonitor)
}

TrelloClipboard.prototype.setValue = function (value) {
    this.value = value;
}

var clip = new TrelloClipboard();
clip.setValue("test");

To list all local groups which have users assigned to them, use this command:

cut -d: -f1 /etc/group | sort

For more info- > Unix groups, Cut command, sort command

You don't need case in the where statement, just use parentheses and or:

Select * From Times
WHERE StartDate <= @Date AND EndDate >= @Date
AND (
    (@day = 'Monday' AND Monday = 1)
    OR (@day = 'Tuesday' AND Tuesday = 1)
    OR Wednesday = 1
)

Additionally, your syntax is wrong for a case. It doesn't append things to the string--it returns a single value. You'd want something like this, if you were actually going to use a case statement (which you shouldn't):

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)
AND 1 = CASE WHEN @day = 'Monday' THEN Monday
             WHEN @day = 'Tuesday' THEN Tuesday
             ELSE Wednesday
        END 

And just for an extra umph, you can use the between operator for your date:

where @Date between StartDate and EndDate

Making your final query:

select
    * 
from 
    Times
where
    @Date between StartDate and EndDate
    and (
        (@day = 'Monday' and Monday = 1)
        or (@day = 'Tuesday' and Tuesday = 1)
        or Wednesday = 1
    )

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob;

As of Spring 5.2.4 (Spring Boot v2.2.6.RELEASE) PathMatchConfigurer.setUseSuffixPatternMatch and ContentNegotiationConfigurer.favorPathExtension have been deprecated ( https://spring.io/blog/2020/03/24/spring-framework-5-2-5-available-now and https://github.com/spring-projects/spring-framework/issues/24179).

The real problem is that the client requests a specific media type (like .com) and Spring added all those media types by default. In most cases your REST controller will only produce JSON so it will not support the requested output format (.com). To overcome this issue you should be all good by updating your rest controller (or specific method) to support the 'ouput' format (@RequestMapping(produces = MediaType.ALL_VALUE)) and of course allow characters like a dot ({username:.+}).

Example:

@RequestMapping(value = USERNAME, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public class UsernameAPI {

    private final UsernameService service;

    @GetMapping(value = "/{username:.+}", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.ALL_VALUE)
    public ResponseEntity isUsernameAlreadyInUse(@PathVariable(value = "username") @Valid @Size(max = 255) String username) {
        log.debug("Check if username already exists");
        if (service.doesUsernameExist(username)) {
            return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
        }
        return ResponseEntity.notFound().build();
    }
}

Spring 5.3 and above will only match registered suffixes (media types).

The line #include "stdafx.h" must be the first line at the top of each source file, before any other header files are included.

If what you've shown is the entire .cxx file, then you did forget to include stdafx.h in that file.

if you need to find square root without using sqrt(),use root=pow(x,0.5).

Where x is value whose square root you need to find.

It looks like ng-attr is a new directive in AngularJS 1.1.4 that you can possibly use in this case.

<!-- example -->
<a ng-attr-title="{{product.shortDesc}}"></a>

However, if you stay with 1.0.7, you can probably write a custom directive to mirror the effect.

You are right, the function you're looking for is array_multisort().

Here's an example taken straight from the manual and adapted to your case:

$price = array();
foreach ($inventory as $key => $row)
{
    $price[$key] = $row['price'];
}
array_multisort($price, SORT_DESC, $inventory);

As of PHP 5.5.0 you can use array_column() instead of that foreach:

$price = array_column($inventory, 'price');

array_multisort($price, SORT_DESC, $inventory);

I suggest using one of the exchange methods that accepts an HttpEntity for which you can also set the HttpHeaders. (You can also specify the HTTP method you want to use.)

For example,

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));

HttpEntity<String> entity = new HttpEntity<>("body", headers);

restTemplate.exchange(url, HttpMethod.POST, entity, String.class);

I prefer this solution because it's strongly typed, ie. exchange expects an HttpEntity.

However, you can also pass that HttpEntity as a request argument to postForObject.

HttpEntity<String> entity = new HttpEntity<>("body", headers);
restTemplate.postForObject(url, entity, String.class); 

This is mentioned in the RestTemplate#postForObject Javadoc.

The request parameter can be a HttpEntity in order to add additional HTTP headers to the request.

Add comments for two different columns of the EMPLOYEE table :

COMMENT ON EMPLOYEE
     (WORKDEPT IS 'see DEPARTMENT table for names',
     EDLEVEL IS 'highest grade level passed in school' )

If you want to give your user all read permissions, you could use:

EXEC sp_addrolemember N'db_datareader', N'your-user-name'

That adds the default db_datareader role (read permission on all tables) to that user.

There's also a db_datawriter role - which gives your user all WRITE permissions (INSERT, UPDATE, DELETE) on all tables:

EXEC sp_addrolemember N'db_datawriter', N'your-user-name'

If you need to be more granular, you can use the GRANT command:

GRANT SELECT, INSERT, UPDATE ON dbo.YourTable TO YourUserName
GRANT SELECT, INSERT ON dbo.YourTable2 TO YourUserName
GRANT SELECT, DELETE ON dbo.YourTable3 TO YourUserName

and so forth - you can granularly give SELECT, INSERT, UPDATE, DELETE permission on specific tables.

This is all very well documented in the MSDN Books Online for SQL Server.

And yes, you can also do it graphically - in SSMS, go to your database, then Security > Users, right-click on that user you want to give permissions to, then Properties adn at the bottom you see "Database role memberships" where you can add the user to db roles.

Here is a simple but efficient version of code:

def get_all_subclasses(cls):
    subclass_list = []

    def recurse(klass):
        for subclass in klass.__subclasses__():
            subclass_list.append(subclass)
            recurse(subclass)

    recurse(cls)

    return set(subclass_list)

Its time complexity is O(n) where n is the number of all subclasses if there's no multiple inheritance. It's more efficient than the functions that recursively create lists or yield classes with generators, whose complexity could be (1) O(nlogn) when the class hierarchy is a balanced tree or (2) O(n^2) when the class hierarchy is a biased tree.

On Windows, Subversion stores the auth data in %APPDATA%\Subversion\auth. The passwords however are stored encrypted, not in plaintext.

You can decrypt those, but only if you log in to Windows as the same user for which the auth data was saved.

Someone even wrote a tool to decrypt those. Never tried the tool myself so I don't know how well it works, but you might want to try it anyway:

http://www.leapbeyond.com/ric/TSvnPD/

Update: In TortoiseSVN 1.9 and later, you can do it without any additional tools:

Settings Dialog -> Saved Data, then click the "Clear..." button right of the text "Authentication Data". A new dialog pops up, showing all stored authentication data where you can chose which one(s) to clear. Instead of clearing, hold down the Shift and Ctrl button, and then double click on the list. A new column is shown in the dialog which shows the password in clear.

There are a number of reasons why the analysis portion of a compiler is normally separated into lexical analysis and parsing ( syntax analysis) phases.

1. Simplicity of design is the most important consideration. The separation of lexical and syntactic analysis often allows us to simplify at least one of these tasks. For example, a parser that had to deal with comments and white space as syntactic units would be. Considerably more complex than one that can assume comments and white space have already been removed by the lexical analyzer. If we are designing a new language, separating lexical and syntactic concerns can lead to a cleaner overall language design.
2. Compiler efficiency is improved. A separate lexical analyzer allows us to apply specialized techniques that serve only the lexical task, not the job of parsing. In addition, specialized buffering techniques for reading input characters can speed up the compiler significantly.
3. Compiler portability is enhanced. Input-device-specific peculiarities can be restricted to the lexical analyzer.

When you change an ASP.NET website's configuration file, it restarts the application to reflect the changes...

When you do an IIS reset, that restarts all applications running on that IIS instance.

Try this:

/\d{3}-(?:(apple|banana)-)?\d{3}/

One more option is to add the path of the privatekey file like this in terminal:

ssh-add "path to the privatekeyfile"

and then execute the pull command

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

I would do a

git diff commit1..commit2 filepattern | git-apply --index && git commit

This way you can limit the range of commits for a filepattern from a branch.

It is stolen from Re: How to pull only a few files from one branch to another?

In my case, my Dockerfile is written like a template containing placeholders which I'm replacing with real value using my configuration file.

So I couldn't specify this file directly but pipe it into the docker build like this:

sed "s/%email_address%/$EMAIL_ADDRESS/;" ./Dockerfile | docker build -t katzda/bookings:latest . -f -;

But because of the pipe, the COPY command didn't work. But the above way solves it by -f - (explicitly saying file not provided). Doing only - without the -f flag, the context AND the Dockerfile are not provided which is a caveat.

I came up with a similar example. Again, the rotation keyword is.. well, it's key.

from pylab import *
fig = figure()
ax = fig.add_subplot(111)
ax.bar( [0,1,2], [1,3,5] )
ax.set_xticks( [ 0.5, 1.5, 2.5 ] )
ax.set_xticklabels( ['tom','dick','harry'], rotation=45 ) ;

that is an error.

first of all, first line should be like this (be careful of capitals)

class Test(object):

Whenever you call a method of a class, it gets itself as the first argument (hence the name self) and method_two gives this error

Basically, you're not allowed to request JSON data from another domain via AJAX due to same-origin policy. AJAX allows you to fetch data after a page has already loaded, and then execute some code/call a function once it returns. We can't use AJAX but we are allowed to inject <script> tags into our own page and those are allowed to reference scripts hosted at other domains.

Usually you would use this to include libraries from a CDN such as jQuery. However, we can abuse this and use it to fetch data instead! JSON is already valid JavaScript (for the most part), but we can't just return JSON in our script file, because we have no way of knowing when the script/data has finished loading and we have no way of accessing it unless it's assigned to a variable or passed to a function. So what we do instead is tell the web service to call a function on our behalf when it's ready.

For example, we might request some data from a stock exchange API, and along with our usual API parameters, we give it a callback, like ?callback=callThisWhenReady. The web service then wraps the data with our function and returns it like this: callThisWhenReady({...data...}). Now as soon as the script loads, your browser will try to execute it (as normal), which in turns calls our arbitrary function and feeds us the data we wanted.

It works much like a normal AJAX request except instead of calling an anonymous function, we have to use named functions.

jQuery actually supports this seamlessly for you by creating a uniquely named function for you and passing that off, which will then in turn run the code you wanted.

^{Due to the fact that I answered this in 2014, I have updated my answer to account for more recent versions of ansible.}

Yes, you can do it at the host/inventory level (Which became possible on newer ansible versions) or global level:

inventory:

Add the following.

ansible_ssh_common_args='-o StrictHostKeyChecking=no'

host:

Add the following.

ansible_ssh_extra_args='-o StrictHostKeyChecking=no'

hosts/inventory options will work with connection type ssh and not paramiko. Some people may strongly argue that inventory and hosts is more secure because the scope is more limited.

global:

Ansible User Guide - Host Key Checking

• You can do it either in the /etc/ansible/ansible.cfg or ~/.ansible.cfg file:

  [defaults]
  host_key_checking = False
  

• Or you can setup and env variable (this might not work on newer ansible versions):

  export ANSIBLE_HOST_KEY_CHECKING=False
  

Anaconda has not updated python internally to 3.6.

a) Method 1

1. If you wanted to update you will type conda update python
2. To update anaconda type conda update anaconda

3. If you want to upgrade between major python version like 3.5 to 3.6, you'll have to do

   conda install python=$pythonversion$
   

b) Method 2 - Create a new environment (Better Method)

conda create --name py36 python=3.6

c) To get the absolute latest python(3.6.5 at time of writing)

conda create --name py365 python=3.6.5 --channel conda-forge

You can see all this from here

Also, refer to this for force upgrading

EDIT: Anaconda now has a Python 3.6 version here

#multiplying each element in the list and adding it into an empty list

print(results)

In my case I ran this command even if the table wasn't visible in PhpMyAdmin :

DROP TABLE mytable

then

Worked for me !

You need to wrap your method call into another one, where you do not throw checked exceptions. You can still throw anything that is a subclass of RuntimeException.

A normal wrapping idiom is something like:

private void safeFoo(final A a) {
    try {
        a.foo();
    } catch (Exception ex) {
        throw new RuntimeException(ex);
    }
}

(Supertype exception Exception is only used as example, never try to catch it yourself)

Then you can call it with: as.forEach(this::safeFoo).

$date = strtotime("2017-12-11");
$newDate = date("Y-m-d", strtotime("+1 month", $date));

If you want to increment by days you can also do it

$date = strtotime("2017-12-11");
$newDate = date("Y-m-d", strtotime("+5 day", $date));

string Index = i;
            string FileName = "Mutton" + Index + ".xml";
            XmlDocument xmlDoc = new XmlDocument();

            var path = Path.Combine(Server.MapPath("~/Content/FilesXML"), FileName);
            xmlDoc.Load(path); // Can use xmlDoc.LoadXml(YourString);

this is the best Solution to get the path what is exactly need for now

They have slightly different purposes.

• exec() is for calling a system command, and perhaps dealing with the output yourself.
• system() is for executing a system command and immediately displaying the output - presumably text.
• passthru() is for executing a system command which you wish the raw return from - presumably something binary.

Regardless, I suggest you not use any of them. They all produce highly unportable code.

The key here is to unlist the row first.

colnames(DF) <- as.character(unlist(DF[1,]))
DF = DF[-1, ]

If you need the full path of your URL, you can use vanilla Javascript:

window.location.href

To get just the path (minus domain name), you can use:

window.location.pathname

console.log(window.location.pathname); //yields: "/js" (where snippets run)_x000D_
console.log(window.location.href);     //yields: "https://stacksnippets.net/js"

Source: Location pathname Property - W3Schools

If you are not already using "react-router" you can install it using:

yarn add react-router

then in a React.Component within a "Route", you can call:

this.props.location.pathname

This returns the path, not including the domain name.

Thanks @abdulla-zulqarnain!

While this question is really old. I believe there is a much simpler approach in numpy (a one liner).

import numpy as np

list = [1,3,9,5,2,5,6,9,7]

np.diff(np.sign(np.diff(list))) #the one liner

#output
array([ 0, -2,  0,  2,  0,  0, -2])

To find a local max or min we essentially want to find when the difference between the values in the list (3-1, 9-3...) changes from positive to negative (max) or negative to positive (min). Therefore, first we find the difference. Then we find the sign, and then we find the changes in sign by taking the difference again. (Sort of like a first and second derivative in calculus, only we have discrete data and don't have a continuous function.)

The output in my example does not contain the extrema (the first and last values in the list). Also, just like calculus, if the second derivative is negative, you have max, and if it is positive you have a min.

Thus we have the following matchup:

[1,  3,  9,  5,  2,  5,  6,  9,  7]
    [0, -2,  0,  2,  0,  0, -2]
        Max     Min         Max

If I properly understood your question, supposing your running script is

/relative/path/to/script/index.php

This would give you the parent directory of your running script relative to the document www:

$parent_dir = dirname(dirname($_SERVER['SCRIPT_NAME'])) . '/';
//$parent_dir will be '/relative/path/to/'

If you want the parent directory of your running script relative to server root:

$parent_dir = dirname(dirname($_SERVER['SCRIPT_FILENAME'])) . '/';
//$parent_dir will be '/root/some/path/relative/path/to/'

On Window machine install any version of Git. I installed

Git-2.14.1-64-bit.exe

. Got to search program and search for git.exe. The file can be located under

C:\Users\sd\AppData\Local\Programs\Git\bin\git.exe

.

Open Intelli IDEA>Settings>Version Control>Git. On Path To Git executable add the path. Click on Test button. It will show a message as

Git executed successfully

Now click on Apply and Save. This will solve the issue. .

In addition to AIXroot's answer, there is also a logout function that can be used to write a utmp logout record. So if you don't have any processes for user xxxx, but userdel says "userdel: account xxxx is currently in use", you can add a logout record manually. Create a file logout.c like this:

#include <stdio.h>
#include <utmp.h>

int main(int argc, char *argv[])
{
  if (argc == 2) {
    return logout(argv[1]);
  }
  else {
    fprintf(stderr, "Usage: logout device\n");
    return 1;
  }
}

Compile it:

gcc -lutil -o logout logout.c

And then run it for whatever it says in the output of finger's "On since" line(s) as a parameter:

# finger xxxx
Login: xxxx                             Name:
Directory: /home/xxxx                   Shell: /bin/bash

Following the previous example but with the new nbformat lib version :

import nbformat
from nbconvert import PythonExporter

def convertNotebook(notebookPath, modulePath):

  with open(notebookPath) as fh:
    nb = nbformat.reads(fh.read(), nbformat.NO_CONVERT)

  exporter = PythonExporter()
  source, meta = exporter.from_notebook_node(nb)

  with open(modulePath, 'w+') as fh:
    fh.writelines(source.encode('utf-8'))

var test = {'red':'#FF0000', 'blue':'#0000FF'};_x000D_
delete test.blue; // or use => delete test['blue'];_x000D_
console.log(test);

this deletes test.blue

If Resources is the root path, best way to access file.json would be via /data/file.json

The error means you cannot use the local variable mi inside an inner class.

To use a variable inside an inner class you must declare it final. As long as mi is the counter of the loop and final variables cannot be assigned, you must create a workaround to get mi value in a final variable that can be accessed inside inner class:

final Integer innerMi = new Integer(mi);

So your code will be like this:

for (int mi=0; mi<colors.length; mi++){

    String pos = Character.toUpperCase(colors[mi].charAt(0)) + colors[mi].substring(1);
    JMenuItem Jmi =new JMenuItem(pos);
    Jmi.setIcon(new IconA(colors[mi]));

    // workaround:
    final Integer innerMi = new Integer(mi);

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

        mnForeground.add(Jmi);
    }
}

There are probably better options, but I use and kind of like TextWrangler for basic hex editing. File -> hex Dump File

If I understand you correctly, you can use a combination of Series.isin() and DataFrame.append():

In [80]: df1
Out[80]:
   rating  user_id

6       2  0x1d14L
7       0   0xdafL
8       0  0x1d14L

This is essentially the algorithm you described as "clunky", using idiomatic pandas methods. Note the duplicate row indices. Also, note that this won't give you the expected output if df1 and df2 have no overlapping row indices, i.e., if

In [93]: df1.index & df2.index
Out[93]: Int64Index([], dtype='int64')

In fact, it won't give the expected output if their row indices are not equal.

What I do is say in the Terminal:

$ xcrun swift -version

Output for Xcode 6.3.2 is:

Apple Swift version 1.2 (swiftlang-602.0.53.1 clang-602.0.53)

Of course that assumes that your xcrun is pointing at your copy of Xcode correctly. If, like me, you're juggling several versions of Xcode, that can be a worry! To make sure that it is, say

$ xcrun --find swift

and look at the path to Xcode that it shows you. For example:

/Applications/Xcode.app/...

If that's your Xcode, then the output from -version is accurate. If you need to repoint xcrun, use the Command Line Tools pop-up menu in Xcode's Locations preference pane.

Use the $( ... ) construct:

hash=$(genhash --use-ssl -s $IP -p 443 --url $URL | grep MD5 | grep -c $MD5)

Go on using tabTextAppearance as you did but

1) to fix the capital letter side effect add textAllCap in your style :

<style name="MyTabLayoutTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse">
    <item name="android:textSize">14sp</item>
    <item name="android:textAllCaps">true</item>
</style>

2) to fix the selected tab color side effect add in TabLayout xml the following library attributes :

app:tabSelectedTextColor="@color/color1"
app:tabTextColor="@color/color2" 

Hope this helps.

you can do like this :

public void selectDropDownValue(String ValueToSelect)

    webelement findDropDownValue=driver.findElements(By.id("id1"))    //this will find that dropdown 

    wait.until(ExpectedConditions.visibilityOf(findDropDownValue));    // wait till that dropdown appear

    super.highlightElement(findDropDownValue);   // highlight that dropdown     

    new Select(findDropDownValue).selectByValue(ValueToSelect);    //select that option which u had passed as argument
}

Leave Hungarian to the Hungarians.

In the example I'd even leave out the definitive article and just go with

private const int Answer = 42;

Is that answer or is that the answer?

*Made edit as Pascal strictly correct, however I was thinking the question was seeking more of an answer to life, the universe and everything.

I couldn't use

getClass().getResource("views/view.fxml")

because I put my controller class into "controllers" package, so here is my solution:

getClass().getResource("../views/view.fxml")

I'm using SourceTree along with TortoiseMerge/Diff, which is very easy and convinient diff/merge tool.

If you'd like to use it as well, then:

1. Get standalone version of TortoiseMerge/Diff (quite old, since it doesn't ship standalone since version 1.6.7 of TortosieSVN, that is since July 2011). Links and details in this answer.

2. Unzip TortoiseIDiff.exe and TortoiseMerge.exe to any folder (c:\Program Files (x86)\Atlassian\SourceTree\extras\ in my case).

3. In SourceTree open Tools > Options > Diff > External Diff / Merge. Select TortoiseMerge in both dropdown lists.

4. Hit OK and point SourceTree to your location of TortoiseIDiff.exe and TortoiseMerge.exe.

After that, you can select Resolve Conflicts > Launch External Merge Tool from context menu on each conflicted file in your local repository. This will open up TortoiseMerge, where you can easily deal with all the conflicts, you have. Once finished, simply close TortoiseMerge (you don't even need to save changes, this will probably be done automatically) and after few seconds SourceTree should handle that gracefully.

The only problem is, that it automatically creates backup copy, even though proper option is unchecked.

Unrelated to the OP's problem, but my issue was that I'm a noob shell scripter. All the other languages I've used require parentheses to invoke methods, whereas shell doesn't seem to like that.

function do_something() {
  # do stuff here
}

# bad
do_something()

# works
do_something

When you say:

$user = $_POST["username"];

You're asking the PHP interpreter to assign $user the value of the $_POST array that has a key (or index) of username. If it doesn't exist, PHP throws a fit.

Use isset($_POST['user']) to check for the existence of that variable:

if (isset($_POST['user'])) {
  $user = $_POST["username"];
  ...

No siblings solution:

var x = $('#xxx').parent().html();
alert(x);

Universal solution:

// no cloning necessary    
var x = $('#xxx').wrapAll('<div>').parent().html(); 
alert(x);

Fiddle here: http://jsfiddle.net/ezmilhouse/Mv76a/

That example is pretty vague, but maybe something like this?

items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [''.join(items[3:6])]

It basically does a splice (or assignment to a slice) operation. It removes items 3 to 6 and inserts a new list in their place (in this case a list with one item, which is the concatenation of the three items that were removed.)

For any type of list, you could do this (using the + operator on all items no matter what their type is):

items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [reduce(lambda x, y: x + y, items[3:6])]

This makes use of the reduce function with a lambda function that basically adds the items together using the + operator.

I have an idea. Why not use the ascii_lowercase constant?

For example, running the following code:

# string module, contains constant ascii_lowercase which is all the lowercase
# letters of the English alphabet
import string
# Example value of s, a string
s = 'aaabcabccd'
# Result variable to store the resulting string
result = ''
# Goes through each letter in the alphabet and checks how many times it appears.
# If a letter appears at least oce, then it is added to the result variable
for letter in string.ascii_letters:
    if s.count(letter) >= 1:
        result+=letter

# Optional three lines to convert result variable to a list for sorting
# and then back to a string
result = list(result)
result.sort()
result = ''.join(result)

print(result)

Will print 'abcd'

There you go, all duplicates removed and optionally sorted

I found out that this simple assignmnent also works:

dateOriginal = new Date();
cloneDate = new Date(dateOriginal);

But I don't know how "safe" it is. Successfully tested in IE7 and Chrome 19.

Just adding

left:15%; 

into my css menu of

#menu li {
float: left;
position:relative;
left: 15%;
list-style:none;
}

did the centering trick too

Below solution is a shorthand for @Andy Wilkinson's solution, except that it doesn't have to use a separate class or on a @Bean annotated method.

application.yml:

input:
  name: raja
  age: 12
  somedata:
    abcd: 1 
    bcbd: 2
    cdbd: 3

SomeComponent.java:

@Component
@EnableConfigurationProperties
@ConfigurationProperties(prefix = "input")
class SomeComponent {

    @Value("${input.name}")
    private String name;

    @Value("${input.age}")
    private Integer age;

    private HashMap<String, Integer> somedata;

    public HashMap<String, Integer> getSomedata() {
        return somedata;
    }

    public void setSomedata(HashMap<String, Integer> somedata) {
        this.somedata = somedata;
    }

}

We can club both @Value annotation and @ConfigurationProperties, no issues. But getters and setters are important and @EnableConfigurationProperties is must to have the @ConfigurationProperties to work.

I tried this idea from groovy solution provided by @Szymon Stepniak, thought it will be useful for someone.

Need an edge-to-edge design? Drop the parent .container or .container-fluid.

Still if you need to remove padding from .row and immediate child columns you have to add the class .no-gutters with the code from @Brian above to your own CSS file, actually it's Not 'right out of the box', check here for official details on the final Bootstrap 4 release: https://getbootstrap.com/docs/4.0/layout/grid/#no-gutters

Use the css property overflow . For example:

  .item{
    width : 100px;
    overflow:hidden;
  }

The overflow property can have one of many values like ( hidden , scroll , visible ) .. you can als control the overflow in one direction only using overflow-x or overflow-y.

I hope this helps.

May be you are using this checking :

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
}

To resolve this you need to import android.provider.DocumentsContract class.

To resolve this issue you'll need to set the build SDK version to 19 (4.4) or higher to have API level 19 symbols available while compiling.

First, use the SDK Manager to download API 19 if you don't have it yet. Then, configure your project to use API 19:

• In Android Studio: File -> Project Structure -> General Settings -> Project SDK.
• In Eclipse ADT: Project Properties -> Android -> Project Build Target

I haven't personally checked, but hadoop-yarn-container-virtual-memory-understanding-and-solving-container-is-running-beyond-virtual-memory-limits-errors sounds very reasonable

I solved the issue by changing yarn.nodemanager.vmem-pmem-ratio to a higher value , and I would agree that:

Another less recommended solution is to disable the virtual memory check by setting yarn.nodemanager.vmem-check-enabled to false.

jQuery version would be something like below:

function load(recieving_id){
    $('#roommate_but').prop('disabled', true);
    $.get('include.inc.php?i=' + recieving_id, function(data) {
        $("#roommate_but").html(data);

You must use an integer value for the CURLOPT_SSLVERSION value, not a string as listed above

Try this:

curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 6); //Integer NOT string TLS v1.2

http://php.net/manual/en/function.curl-setopt.php

value should be an integer for the following values of the option parameter: CURLOPT_SSLVERSION

One of

CURL_SSLVERSION_DEFAULT (0)
CURL_SSLVERSION_TLSv1 (1)
CURL_SSLVERSION_SSLv2 (2)
CURL_SSLVERSION_SSLv3 (3)
CURL_SSLVERSION_TLSv1_0 (4)
CURL_SSLVERSION_TLSv1_1 (5)
CURL_SSLVERSION_TLSv1_2 (6).

You might need to run it with sudo.

I had similar situation and here is my approach which is somewhat different:

 HADOOP_USER_NAME=hdfs hdfs dfs -put /root/MyHadoop/file1.txt /

What you actually do is you read local file in accordance to your local permissions but when placing file on HDFS you are authenticated like user hdfs. You can do this with other ID (beware of real auth schemes configuration but this is usually not a case).

Advantages:

1. Permissions are kept on HDFS.
2. You don't need sudo.
3. You don't need actually appropriate local user 'hdfs' at all.
4. You don't need to copy anything or change permissions because of previous points.

Try this :

$obj = @{
    SomeProp = "Hello"
}

Write-Host "Property Value is $($obj."SomeProp")"

Having the .htaccess file on the root folder, add this line. Make sure to delete all other useless rules you tried before:

Options -Indexes

Or try:

Options All -Indexes

As others have answered, you probably have a DATETIME (or other variation) column and not a DATE datatype.

Here's a condition that works for all, including DATE:

SELECT * 
FROM xxx 
WHERE dates >= '20121026' 
  AND dates <  '20121028'    --- one day after 
                             --- it is converted to '2012-10-28 00:00:00.000'
 ;

@Aaron Bertrand has blogged about this at: What do BETWEEN and the devil have in common?

I try with http servlet and I find this issue when I write duplicated @WebServlet ,I encountered with this issue.After I remove or change @WebServlet value it is working.

1.Class

@WebServlet("/display")
public class MyFirst extends HttpServlet {

2.Class

@WebServlet("/display")
public class MySecond extends HttpServlet {

With Java 8 you can write:

OffsetDateTime utc = OffsetDateTime.now(ZoneOffset.UTC);

To answer your comment, you can then convert it to a Date (unless you depend on legacy code I don't see any reason why) or to millis since the epochs:

Date date = Date.from(utc.toInstant());
long epochMillis = utc.toInstant().toEpochMilli();

This launches the Scheduled Tasks MMC Control Panel:

%SystemRoot%\system32\taskschd.msc /s

Older versions of windows had a splash screen for the MMC control panel and the /s switch would supress it. It's not needed but doesn't hurt either.

boiled this down to a one liner sets the variable "$port389Open" to True or false - its fast and easy to replicate for a list of ports

try{$socket = New-Object Net.Sockets.TcpClient($ipAddress,389);if($socket -eq $null){$Port389Open = $false}else{Port389Open = $true;$socket.close()}}catch{Port389Open = $false}

If you want ot go really crazy you can return the an entire array-

Function StdPorts($ip){
    $rst = "" |  select IP,Port547Open,Port135Open,Port3389Open,Port389Open,Port53Open
    $rst.IP = $Ip
    try{$socket = New-Object Net.Sockets.TcpClient($ip,389);if($socket -eq $null){$rst.Port389Open = $false}else{$rst.Port389Open = $true;$socket.close();$ipscore++}}catch{$rst.Port389Open = $false}
    try{$socket = New-Object Net.Sockets.TcpClient($ip,53);if($socket -eq $null){$rst.Port53Open = $false}else{$rst.Port53Open = $true;$socket.close();$ipscore++}}catch{$rst.Port53Open = $false}
    try{$socket = New-Object Net.Sockets.TcpClient($ip,3389);if($socket -eq $null){$rst.Port3389Open = $false}else{$rst.Port3389Open = $true;$socket.close();$ipscore++}}catch{$rst.Port3389Open = $false}
    try{$socket = New-Object Net.Sockets.TcpClient($ip,547);if($socket -eq $null){$rst.Port547Open = $false}else{$rst.Port547Open = $true;$socket.close();$ipscore++}}catch{$rst.Port547Open = $false}
    try{$socket = New-Object Net.Sockets.TcpClient($ip,135);if($socket -eq $null){$rst.Port135Open = $false}else{$rst.Port135Open = $true;$socket.close();$SkipWMI = $False;$ipscore++}}catch{$rst.Port135Open = $false}
    Return $rst
}

If this is ASP.net-Core then you are mixing web API versions. Have the action return a derived IActionResult because in your current code the framework is treating HttpResponseMessage as a model.

[Route("api/[controller]")]
public class DownloadController : Controller {
    //GET api/download/12345abc
    [HttpGet("{id}"]
    public async Task<IActionResult> Download(string id) {
        Stream stream = await {{__get_stream_based_on_id_here__}}

        if(stream == null)
            return NotFound(); // returns a NotFoundResult with Status404NotFound response.

        return File(stream, "application/octet-stream"); // returns a FileStreamResult
    }    
}

Your current combination of a POST with an HTTP 204 response is fine.

Using a POST as a universal replacement for a GET is not supported by the RFC, as each has its own specific purpose and semantics.

The purpose of a GET is to retrieve a resource. Therefore, while allowed, an HTTP 204 wouldn't be the best choice since content IS expected in the response. An HTTP 404 Not Found or an HTTP 410 Gone would be better choices if the server was unable to provide the requested resource.

The RFC also specifically calls out an HTTP 204 as an appropriate response for PUT, POST and DELETE, but omits it for GET.

See the RFC for the semantics of GET.

There are other response codes that could also be returned, indicating no content, that would be more appropriate than an HTTP 204.

For example, for a conditional GET you could receive an HTTP 304 Not Modified response which would contain no body content.

You are trying to read xls with explicit implementation poi classes for xlsx.

G:\Selenium Jar Files\TestData\Data.xls

Either use HSSFWorkbook and HSSFSheet classes or make your implementation more generic by using shared interfaces, like;

Change:

XSSFWorkbook workbook = new XSSFWorkbook(file);

To:

 org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(file);

And Change:

XSSFSheet sheet = workbook.getSheetAt(0);

To:

org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);

In simple words:

The code you see under if __name__ == "__main__": will only get called upon when your python file is executed as "python example1.py".

However, if you wish to import your python file 'example1.py' as a module to work with another python file say 'example2.py', the code under if __name__ == "__main__": will not run or take any effect.

If you wanna find just the word like 'are' in "How are you?" and not like 'are' in 'hare'

$word=" are ";
$str="How are you?";
if(strpos($word,$str) !== false){
echo 1;
 }

Create a helper using the code I created belows and name it controller_helper.php.

Autoload your helper in the autoload.php file under config.

From your method call controller('name') to load the controller.

Note that name is the filename of the controller.

This method will append '_controller' to your controller 'name'. To call a method in the controller just run $this->name_controller->method(); after you load the controller as described above.

<?php

if(!function_exists('controller'))
{
    function controller($name)
    {
        $filename = realpath(__dir__ . '/../controllers/'.$name.'.php');

        if(file_exists($filename))
        {
            require_once $filename;

            $class = ucfirst($name);

            if(class_exists($class))
            {
                $ci =& get_instance();

                if(!isset($ci->{$name.'_controller'}))
                {
                    $ci->{$name.'_controller'} = new $class();
                }
            }
        }
    }
}
?>

But you could make an own link for every from url.

Example: http://example.com?auth=holasite

In this example your site is: example.com

If somebody open that link it's give you the holasite value for the auth variable.

Then just $_GET['auth'] and you have the variable. But you should have a database to store it, and to authorize.

Like: $holasite = http://holasite.com (You could use mysql too..)

And just match it, and you have the url.

This method is a little bit more complicated, but it works. This method is good for a referral system authentication. But where is the site name, you should write an id, and works with that id.

You need to add your tiles into your resource bundle. I mean add all those files to your project make sure to copy all files to project directory option checked.

If you want to return from an outer function with an error without exiting you can use this trick:

do-something-complex() {
  # Using `return` here would only return from `fail`, not from `do-something-complex`.
  # Using `exit` would close the entire shell.
  # So we (ab)use a different feature. :)
  fail() { : "${__fail_fast:?$1}"; }

  nested-func() {
      try-this || fail "This didn't work"
      try-that || fail "That didn't work"
  }
  nested-func
}

Trying it out:

$ do-something-complex
try-this: command not found
bash: __fail_fast: This didn't work

This has the added benefit/drawback that you can optionally turn off this feature: __fail_fast=x do-something-complex.

Note that this causes the outermost function to return 1.

I am not sure how to see the actual rows/records that come back.

Stored procedures do not return records. They may have a cursor as an output parameter, which is a pointer to a select statement. But it requires additional action to actually bring back rows from that cursor.

In SQL Developer, you can execute a procedure that returns a ref cursor as follows

var rc refcursor
exec proc_name(:rc)

After that, if you execute the following, it will show the results from the cursor:

print rc

<?php
$start = strtotime("12:00");
$end = // Run query to get datetime value from db
$elapsed = $end - $start;
echo date("H:i", $elapsed);
?>

Python uses duck typing, so it doesn't need special syntax to handle multiple types.

If you're from a C++ background, you'll remember that, as long as the operations used in the template function/class are defined on some type T (at the syntax level), you can use that type T in the template.

So, basically, it works the same way:

1. define a contract for the type of items you want to insert in the binary tree.
2. document this contract (i.e. in the class documentation)
3. implement the binary tree using only operations specified in the contract
4. enjoy

You'll note however, that unless you write explicit type checking (which is usually discouraged), you won't be able to enforce that a binary tree contains only elements of the chosen type.

If you use maven, check that you have this plugin in your pom.xml:

    <build>
        <plugins>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>3.2.0</version>
                <executions>
                    <!-- Attach the shade goal into the package phase -->
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

        </plugins>
    </build>

It will put your dependency (the exception reason) to your jar.

FYI: this will include all dependencies inflated in the final jar

You could try:

$(SolutionDir)..\..\

For Laravel >= 5.5

• Run npm install font-awesome --save
• Add @import "~font-awesome/scss/font-awesome.scss"; in resources/assets/saas/app.scss
• Run npm run dev (or npm run watch or even npm run production)

You cannot use a variable in a create table statement. The best thing I can suggest is to write the entire query as a string and exec that.

Try something like this:

declare @query varchar(max);
set @query = 'create database TEST...';

exec (@query);

Ok. So I think you just need to implement Pagination.

$perPage = 10;

$pageNo = $_GET['page'];

Now find total rows in database.

$totalRows = Get By applying sql query;

$pages = ceil($totalRows/$perPage);    

$offset = ($pageNo - 1) * $perPage + 1

$sql = "SELECT * FROM msgtable WHERE cdate='18/07/2012' LIMIT ".$offset." ,".$perPage

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

In case of a multi-value return function you can't refer to fields or methods of a specific value of the result when calling the function.

And if one of them is an error, it's there for a reason (which is the function might fail) and you should not bypass it because if you do, your subsequent code might also fail miserably (e.g. resulting in runtime panic).

However there might be situations where you know the code will not fail in any circumstances. In these cases you can provide a helper function (or method) which will discard the error (or raise a runtime panic if it still occurs).
This can be the case if you provide the input values for a function from code, and you know they work.
Great examples of this are the template and regexp packages: if you provide a valid template or regexp at compile time, you can be sure they can always be parsed without errors at runtime. For this reason the template package provides the Must(t *Template, err error) *Template function and the regexp package provides the MustCompile(str string) *Regexp function: they don't return errors because their intended use is where the input is guaranteed to be valid.

Examples:

// "text" is a valid template, parsing it will not fail
var t = template.Must(template.New("name").Parse("text"))

// `^[a-z]+\[[0-9]+\]$` is a valid regexp, always compiles
var validID = regexp.MustCompile(`^[a-z]+\[[0-9]+\]$`)

Back to your case

IF you can be certain Get() will not produce error for certain input values, you can create a helper Must() function which would not return the error but raise a runtime panic if it still occurs:

func Must(i Item, err error) Item {
    if err != nil {
        panic(err)
    }
    return i
}

But you should not use this in all cases, just when you're sure it succeeds. Usage:

val := Must(Get(1)).Value

Alternative / Simplification

You can even simplify it further if you incorporate the Get() call into your helper function, let's call it MustGet:

func MustGet(value int) Item {
    i, err := Get(value)
    if err != nil {
        panic(err)
    }
    return i
}

Usage:

val := MustGet(1).Value

how to parse multiple returns in golang

Return map like 'ok' in Golang on normal functions

Problems - no way to get the number of strings automatically (that i know of).

There is a bog-standard way of doing this, which lots of people (including MS) define macros like arraysize for:

#define arraysize(ar)  (sizeof(ar) / sizeof(ar[0]))

It's not a cut and paste. The CASE expression must return a value, and you are returning a string containing SQL (which is technically a value but of a wrong type). This is what you wanted to write, I think:

SELECT * FROM [Purchasing].[Vendor] WHERE  
CASE
  WHEN @url IS null OR @url = '' OR @url = 'ALL'
    THEN PurchasingWebServiceURL LIKE '%'
  WHEN @url = 'blank'
    THEN PurchasingWebServiceURL = ''
  WHEN @url = 'fail'
    THEN PurchasingWebServiceURL NOT LIKE '%treyresearch%'
  ELSE PurchasingWebServiceURL = '%' + @url + '%' 
END

I also suspect that this might not work in some dialects, but can't test now (Oracle, I'm looking at you), due to not having booleans.

However, since @url is not dependent on the table values, why not make three different queries, and choose which to evaluate based on your parameter?

I have just discovered a way to append text and its working fine at least.

 var text = 'Put any text here';
 $('#text').append(text);

You can change text according to your need.

-eq is a mathematical comparison operator. I've never used it for string comparison, relying on == and != for compares.

if [ 'XYZ' == 'ABC' ]; then   # Double equal to will work in Linux but not on HPUX boxes it should be if [ 'XYZ' = 'ABC' ] which will work on both
  echo "Match"
else
  echo "No Match"
fi

Possibly:

puts variable.inspect

Right click in the query pane, select Query Options... and in the Execution->General section (the default when you first open it) there is an Execution time-out setting.

The App-Secret key should be kept private - but when releasing the app they can be reversed by some guys.

for those guys it will not hide, lock the either the ProGuard the code. It is a refactor and some payed obfuscators are inserting a few bitwise operators to get back the jk433g34hg3 String. You can make 5 -15 min longer the hacking if you work 3 days :)

Best way is to keep it as it is, imho.

Even if you store at server side( your PC ) the key can be hacked and printed out. Maybe this takes the longest? Anyhow it is a matter of few minutes or a few hours in best case.

A normal user will not decompile your code.

tools => fiddler options => connections there is a textarea with stuff to jump, delete LH from there

I verified permissions but all was good (mongod:mongod). As I'm working on a large project and from a similar issue in our dev environment where we had a script consuming all available disk space, I could see in the error messages that mongod needs at least 3.7Gb free disk space to run..

I checked my own disk space only to see that less than 2Gb was remaining. After moving / erasing some data I can successfully start mongod again.

Hope this helps ;-)

what platform are you running?..
if its unix, maybe adding

alias java='java -Xmx1g'  

to .bashrc (or similar) work

edit: Changing XmX to Xmx

If you're running an MVC 3 application - in your solution explorer click the show all files icon and then under the Global.asax file there should be a file called YourProjectName.Publish.XML right-click it and then click "Browse With..." and select your favorite browser as the default.

$('#multiselect1').on('change', function(){
    var selected = $(this).find("option:selected");
    var arrSelected = [];
    selected.each(function(){
       arrSelected.push($(this).val());
    });
});

You can use this format

The internal storage is referred to as "external storage" in the API.

As mentioned in the Environment documentation

Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

To distinguish whether "Environment.getExternalStorageDirectory()" actually returned physically internal or external storage, call Environment.isExternalStorageEmulated(). If it's emulated, than it's internal. On newer devices that have internal storage and sdcard slot Environment.getExternalStorageDirectory() will always return the internal storage. While on older devices that have only sdcard as a media storage option it will always return the sdcard.

There is no way to retrieve all storages using current Android API.

I've created a helper based on Vitaliy Polchuk's method in the answer below

How can I get the list of mounted external storage of android device

NOTE: starting KitKat secondary storage is accessible only as READ-ONLY, you may want to check for writability using the following method

/**
 * Checks whether the StorageVolume is read-only
 * 
 * @param volume
 *            StorageVolume to check
 * @return true, if volume is mounted read-only
 */
public static boolean isReadOnly(@NonNull final StorageVolume volume) {
    if (volume.mFile.equals(Environment.getExternalStorageDirectory())) {
        // is a primary storage, check mounted state by Environment
        return android.os.Environment.getExternalStorageState().equals(
                android.os.Environment.MEDIA_MOUNTED_READ_ONLY);
    } else {
        if (volume.getType() == Type.USB) {
            return volume.isReadOnly();
        }
        //is not a USB storagem so it's read-only if it's mounted read-only or if it's a KitKat device
        return volume.isReadOnly() || Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
    }
}

In usecase where you want to serialize/deserialize POCOs, Newtonsoft's JSON library is really good. I use it to persist POCOs within SQL Server as JSON strings in an nvarchar field. Caveat is that since its not true de/serialization, it will not preserve private/protected members and class hierarchy.

For those who are getting the error as:

I/O error on POST request for "anothermachine:31112/url/path";: class path 
resource [fileName.csv] cannot be resolved to URL because it does not exist.

It can be resolved by using the

LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
map.add("file", new FileSystemResource(file));

If the file is not present in the classpath, and an absolute path is required.

Swift 5:

extension Int {

    func secondsToTime() -> String {

        let (h,m,s) = (self / 3600, (self % 3600) / 60, (self % 3600) % 60)

        let h_string = h < 10 ? "0\(h)" : "\(h)"
        let m_string =  m < 10 ? "0\(m)" : "\(m)"
        let s_string =  s < 10 ? "0\(s)" : "\(s)"

        return "\(h_string):\(m_string):\(s_string)"
    }
}

Usage:

let seconds : Int = 119
print(seconds.secondsToTime()) // Result = "00:01:59"

You should use style instead of background color. Try searching holoeverywhere then I think this one will help you solve your problem

This problem is because of the fact that eclipse is not able to find Java ,

Check the java directory cd /Library/Java/JavaVirtualMachines///Contents/Home/jre/bin

If thats not present down JDK from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Once JDK is installed change eclipse.ini file

On Mac: Right click on Eclipse icon and click "Show package Content"

Navigate to eclipse>Contents>Eclipse>eclipse.ini

Open the file and replace the java path after "-vm" with this

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/bin

You can do it using just css without using any jQiuery.

you can put

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

at the top of your car.js file for it to work, or you can do what Raynos said to do.

There's a property spring.resources.staticLocations that can be set in the application.properties. Note that this will override the default locations. See org.springframework.boot.autoconfigure.web.ResourceProperties.

I know this is old, I had a case where I needed the array key to be included in the CSV also, so I updated the script by Jesse Q to do that. I used a string as output, as implode can't add new line (new line is something I added, and should really be there).

Please note, this only works with single value arrays (key, value). but could easily be updated to handle multi-dimensional (key, array()).

function arrayToCsv( array &$fields, $delimiter = ',', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = '';
    foreach ( $fields as $key => $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output = '';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output .= $key;
            $output .= $delimiter;
            $output .= $enclosure . str_replace($enclosure, $enclosure . $enclosure,     $field) . $enclosure;
            $output .= PHP_EOL;
        }
        else {
            $output .= $key;
            $output .= $delimiter;
            $output .= $field;
            $output .= PHP_EOL;
        }
    }

    return  $output ;
}

I have debian 9 and to fix this i used the new library as follows:

ln -s /usr/bin/gpgv /usr/bin/gnupg2

If you have a Red Hat server use yum. apt-get is only for Debian, Ubuntu and some other related linux.

Why would you want to use apt-get anyway? (It seems like you know what yum is.)

If you can't update configuration files but control the code that handles file uploads use HttpContext.Current.Request.GetBufferlessInputStream(true).

The true value for disableMaxRequestLength parameter tells the framework to ignore configured request limits.

I think the answer you are after is implied (if not stated) by Vinko's answer, though it is not spelled out simply. To distinguish whether VAR is set but empty or not set, you can use:

if [ -z "${VAR+xxx}" ]; then echo VAR is not set at all; fi
if [ -z "$VAR" ] && [ "${VAR+xxx}" = "xxx" ]; then echo VAR is set but empty; fi

You probably can combine the two tests on the second line into one with:

if [ -z "$VAR" -a "${VAR+xxx}" = "xxx" ]; then echo VAR is set but empty; fi

However, if you read the documentation for Autoconf, you'll find that they do not recommend combining terms with '-a' and do recommend using separate simple tests combined with &&. I've not encountered a system where there is a problem; that doesn't mean they didn't used to exist (but they are probably extremely rare these days, even if they weren't as rare in the distant past).

You can find the details of these, and other related shell parameter expansions, the test or [ command and conditional expressions in the Bash manual.

I was recently asked by email about this answer with the question:

You use two tests, and I understand the second one well, but not the first one. More precisely I don't understand the need for variable expansion

if [ -z "${VAR+xxx}" ]; then echo VAR is not set at all; fi

Wouldn't this accomplish the same?

if [ -z "${VAR}" ]; then echo VAR is not set at all; fi

Fair question - the answer is 'No, your simpler alternative does not do the same thing'.

Suppose I write this before your test:

VAR=

Your test will say "VAR is not set at all", but mine will say (by implication because it echoes nothing) "VAR is set but its value might be empty". Try this script:

(
unset VAR
if [ -z "${VAR+xxx}" ]; then echo JL:1 VAR is not set at all; fi
if [ -z "${VAR}" ];     then echo MP:1 VAR is not set at all; fi
VAR=
if [ -z "${VAR+xxx}" ]; then echo JL:2 VAR is not set at all; fi
if [ -z "${VAR}" ];     then echo MP:2 VAR is not set at all; fi
)

The output is:

JL:1 VAR is not set at all
MP:1 VAR is not set at all
MP:2 VAR is not set at all

In the second pair of tests, the variable is set, but it is set to the empty value. This is the distinction that the ${VAR=value} and ${VAR:=value} notations make. Ditto for ${VAR-value} and ${VAR:-value}, and ${VAR+value} and ${VAR:+value}, and so on.

As Gili points out in his answer, if you run bash with the set -o nounset option, then the basic answer above fails with unbound variable. It is easily remedied:

if [ -z "${VAR+xxx}" ]; then echo VAR is not set at all; fi
if [ -z "${VAR-}" ] && [ "${VAR+xxx}" = "xxx" ]; then echo VAR is set but empty; fi

Or you could cancel the set -o nounset option with set +u (set -u being equivalent to set -o nounset).

You can view the java doc examples or the example of usage of Predicate here

Basically it is used to filter rows in the resultset based on any specific criteria that you may have and return true for those rows that are meeting your criteria:

 // the age column to be between 7 and 10
    AgeFilter filter = new AgeFilter(7, 10, 3);

    // set the filter.
    resultset.beforeFirst();
    resultset.setFilter(filter);

The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n on input, and conversely on output.

From the C99 standard (the N869 draft document), §7.19.2/2,

A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.

And in §7.19.3/2

Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.

About use of fseek, in §7.19.9.2/4:

For a text stream, either offset shall be zero, or offset shall be a value returned by an earlier successful call to the ftell function on a stream associated with the same file and whence shall be SEEK_SET.

About use of ftell, in §17.19.9.4:

The ftell function obtains the current value of the file position indicator for the stream pointed to by stream. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by the fseek function for returning the file position indicator for the stream to its position at the time of the ftell call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.

I think that’s the most important, but there are some more details.

The file location/path has to relative to your classpath locations. If resources directory is in your classpath you just need "app-context.xml" as file location.

this has been modified in codeigniter 2.2.1...usually not best practice to modify core files, I would always check for updates and 2.2.1 came out in Jan 2015

The answer of crdunst is pretty neat and the best looking answer I've found but there's no explanation on how to use and the code is bigger than needed.

The only code you need:

#element {
    background-color: #cacbcf;
    text-shadow: 2px 2px 4px rgba(0,0,0, 0.5);
    filter: chroma(color=#cacbcf) progid:DXImageTransform.Microsoft.dropshadow(color=#60000000, offX=2, offY=2);
}

First you MUST specify a background-color - if your element should be transparent just copy the background-color of the parent or let it inherit. The color at the chroma-filter must match the background-color to fix those artifacts around the text (but here you must copy the color, you can't write inherit). Note that I haven't shortened the dropshadow-filter - it works but the shadows are then cut to the element dimensions (noticeable with big shadows; try to set the offsets to atleast 4).

TIP: If you want to use colors with transparency (alpha-channel) write in a #AARRGGBB notation, where AA stands for a hexadezimal value of the opacity - from 01 to FE, because FF and ironically also 00 means no transparency and is therefore useless.. ^^ Just go a little lower than in the rgba notation because the shadows aren't soft and the same alpha value would appear darker then. ;)

A nice snippet to convert the alpha value for IE (JavaScript, just paste into the console):

var number = 0.5; //alpha value from the rgba() notation
("0"+(Math.round(0.75 * number * 255).toString(16))).slice(-2);

ISSUES: The text/font behaves like an image after the shadow is applied; it gets pixelated and blurry after you zoom in... But that's IE's issue, not mine.

It takes keyword arguments for the variables:

url_for('add', variable=foo)

Wow, ya'll are overthinking it. It's as simple as the following. Besides, many of those answers aren't understood by the RE2 dialect used by C and golang.

^$

i do in this way ....

NSDate * mydate = [NSDate date];

NSCalendar * mycalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

NSCalendarUnit units = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay;

NSDateComponents * myComponents  = [mycalendar components:units fromDate:mydate];

NSLog(@"%d-%d-%d",myComponents.day,myComponents.month,myComponents.year);

I had a similar problem. As I got a Character from my XML child I had to convert it first to a String (or Integer, if you expect one). The following shows how I solved the problem.

foreach($xml->children() as $newInstr){
        $iInstrument = new Instrument($newInstr['id'],$newInstr->Naam,$newInstr->Key);
        $arrInstruments->offsetSet((String)$iInstrument->getID(), $iInstrument);
    }

Yes, it is a non-type parameter. You can have several kinds of template parameters

• Type Parameters.
  • Types
  • Templates (only classes and alias templates, no functions or variable templates)
• Non-type Parameters
  • Pointers
  • References
  • Integral constant expressions

What you have there is of the last kind. It's a compile time constant (so-called constant expression) and is of type integer or enumeration. After looking it up in the standard, i had to move class templates up into the types section - even though templates are not types. But they are called type-parameters for the purpose of describing those kinds nonetheless. You can have pointers (and also member pointers) and references to objects/functions that have external linkage (those that can be linked to from other object files and whose address is unique in the entire program). Examples:

Template type parameter:

template<typename T>
struct Container {
    T t;
};

// pass type "long" as argument.
Container<long> test;

Template integer parameter:

template<unsigned int S>
struct Vector {
    unsigned char bytes[S];
};

// pass 3 as argument.
Vector<3> test;

Template pointer parameter (passing a pointer to a function)

template<void (*F)()>
struct FunctionWrapper {
    static void call_it() { F(); }
};

// pass address of function do_it as argument.
void do_it() { }
FunctionWrapper<&do_it> test;

Template reference parameter (passing an integer)

template<int &A>
struct SillyExample {
    static void do_it() { A = 10; }
};

// pass flag as argument
int flag;
SillyExample<flag> test;

Template template parameter.

template<template<typename T> class AllocatePolicy>
struct Pool {
    void allocate(size_t n) {
        int *p = AllocatePolicy<int>::allocate(n);
    }
};

// pass the template "allocator" as argument. 
template<typename T>
struct allocator { static T * allocate(size_t n) { return 0; } };
Pool<allocator> test;

A template without any parameters is not possible. But a template without any explicit argument is possible - it has default arguments:

template<unsigned int SIZE = 3>
struct Vector {
    unsigned char buffer[SIZE];
};

Vector<> test;

Syntactically, template<> is reserved to mark an explicit template specialization, instead of a template without parameters:

template<>
struct Vector<3> {
    // alternative definition for SIZE == 3
};

This code is probably good for Python 2. But in Python 3, this will cause an issue, something related to bit encoding. I was trying to make a simple TCP server and encountered the same problem. Encoding worked for me. Try this with sendto command.

clientSocket.sendto(message.encode(),(serverName, serverPort))

Similarly you would use .decode() to receive the data on the UDP server side, if you want to print it exactly as it was sent.

I found this very difficult to get an answer to but eventually figured it out. So I will write the steps below.

1. Before you setup your connection string in code, ensure you actually can access your database. Start obviously by logging into the database server using SSMS (Sql Server Management Studio or it's equivalent in other databases) locally to ensure you have access using whatever details you intend to use.

2. Next (if needed), if you are trying to access the database on a separate server, ensure you can do likewise in SSMS. So setup SSMS on a computer and ensure you can access the server with the username and password to that database server.

If you don't get the above 2 right, you are simply wasting your time as you cant access the database. This can either be because the user you setup is wrong, doesn't have remote access enabled (if needed), or the ports are not opened (if needed), among many other reasons but these being the most common.

Once you have verified that you can access the database using SSMS. The next step, just for the sake of automating the process and avoiding mistakes, is to let the system do the work for you.

3. Start up an empty project, add your choice of Linq to SQL or Dataset (EF is good but the connection string is embedded inside of an EF con string, I want a clean one), and connect to your database using the details verified above in the con string wizzard. Add any table and save the file.

Now go into the web config, and magically, you will see nice clean working connection string there with all the details you need.

{ Below was part of an old post so you can ignore this, I leave it in for reference as its the most basic way to access the database from only code behind. Please scroll down and continue from step 2 below. }

Lets assume the above steps start you off with something like the following as your connection string in the code behind:

string conString = "Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;";

This step is very important. Make sure you have the above format of connection string working before taking the following steps. Make sure you actually can access your data using some form of sql command text which displays some data from a table in labels or text boses or whatever, as this is the simplest way to do a connection string.

Once you are sure the above style works its now time to take the next steps:

1. Export your string literal (the stuff in the quotes, including the quotes) to the following section of the web.config file (for multiple connection strings, just do multiple lines:

<configuration>
    <connectionStrings>
        <add name="conString" connectionString="Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
        <add name="conString2" connectionString="Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
        <add name="conString3" connectionString="Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
    </connectionStrings>
</configuration>

{ The above was part of an old post, after doing the top 3 steps this whole process will be done for you, so you can ignore it. I just leave it here for my own reference. }

2. Now add the following line of code to the C# code behind, prefrably just under the class definition (i.e. not inside a method). This points to the root folder of your project. Essentially it is the project name. This is usually the location of the web.config file (in this case my project is called MyProject.

static Configuration rootWebConfig = WebConfigurationManager.OpenWebConfiguration("/MyProject");

3. Now add the following line of code to the C# code behind. This sets up a string constant to which you can refer in many places throughout your code should you need a conString in different methods.

const string CONSTRINGNAME = "conString";

4. Next add the following line of code to the C# code behind. This gets the connection string from the web.config file with the name conString (from the constant above)

ConnectionStringSettings conString = rootWebConfig.ConnectionStrings.ConnectionStrings[CONSTRINGNAME];

5. Finally, where you origionally would have had something similar to this line of code:

SqlConnection con = new SqlConnection(conString)

you will replace it with this line of code:

SqlConnection con = new SqlConnection(conString.ConnectionString)

After doing these 5 steps your code should work as it did before. Hense the reason you test the constring first in its origional format so you know if it is a problem with the connection string or if it is a problem with the code.

I am new to C#, ASP.Net and Sql Server. So I am sure there must be a better way to do this code. I also would appreicate feedback on how to improve these steps if possible. I have looked all over for something like this but I eventually figured it out after many weeks of hard work. Looking at it myself, I still think, there must be an easier way.

I hope this is helpful.

Before I answer this, I'd like to point out that Chrome and IE 10+ actually supports calc with viewport units.

FIDDLE (In IE10+)

Solution (for other browsers): box-sizing

1) Start of by setting your height as 100vh.

2) With box-sizing set to border-box - add a padding-top of 75vw. This means that the padding will be part f the inner height.

3) Just offset the extra padding-top with a negative margin-top

FIDDLE

div
{
    /*height: calc(100vh - 75vw);*/
    height: 100vh;
    margin-top: -75vw;
    padding-top: 75vw;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    background: pink;
}

Try for this:

boolean blnResult = Arrays.equals(byteArray1, byteArray2);

I am also not sure about this, but try this may be it works.

Your question is based on a false premise.

Arrays are not a primitive type in Java, but they are not objects either ... "

In fact, all arrays in Java are objects¹. Every Java array type has java.lang.Object as its supertype, and inherits the implementation of all methods in the Object API.

... so are they passed by value or by reference? Does it depend on what the array contains, for example references or a primitive type?

Short answers: 1) pass by value, and 2) it makes no difference.

Longer answer:

Like all Java objects, arrays are passed by value ... but the value is the reference to the array. So, when you assign something to a cell of the array in the called method, you will be assigning to the same array object that the caller sees.

This is NOT pass-by-reference. Real pass-by-reference involves passing the address of a variable. With real pass-by-reference, the called method can assign to its local variable, and this causes the variable in the caller to be updated.

But not in Java. In Java, the called method can update the contents of the array, and it can update its copy of the array reference, but it can't update the variable in the caller that holds the caller's array reference. Hence ... what Java is providing is NOT pass-by-reference.

Here are some links that explain the difference between pass-by-reference and pass-by-value. If you don't understand my explanations above, or if you feel inclined to disagree with the terminology, you should read them.

• http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/topic/com.ibm.xlcpp8a.doc/language/ref/cplr233.htm
• http://www.cs.fsu.edu/~myers/c++/notes/references.html

Related SO question:

• Is Java "pass-by-reference" or "pass-by-value"?

Historical background:

The phrase "pass-by-reference" was originally "call-by-reference", and it was used to distinguish the argument passing semantics of FORTRAN (call-by-reference) from those of ALGOL-60 (call-by-value and call-by-name).

• In call-by-value, the argument expression is evaluated to a value, and that value is copied to the called method.

• In call-by-reference, the argument expression is partially evaluated to an "lvalue" (i.e. the address of a variable or array element) that is passed to the calling method. The calling method can then directly read and update the variable / element.

• In call-by-name, the actual argument expression is passed to the calling method (!!) which can evaluate it multiple times (!!!). This was complicated to implement, and could be used (abused) to write code that was very difficult to understand. Call-by-name was only ever used in Algol-60 (thankfully!).

UPDATE

Actually, Algol-60's call-by-name is similar to passing lambda expressions as parameters. The wrinkle is that these not-exactly-lambda-expressions (they were referred to as "thunks" at the implementation level) can indirectly modify the state of variables that are in scope in the calling procedure / function. That is part of what made them so hard to understand. (See the Wikipedia page on Jensen's Device for example.)

^{1. Nothing in the linked Q&A (Arrays in Java and how they are stored in memory) either states or implies that arrays are not objects.}

Try this as a shortcut, not as a definitive solution (see comments):

<script type="text/javascript">
    var ip = location.host;
    alert(ip);
</script>

This solution cannot work in some scenarios but it can help for quick testing. Regards

This script allows you to change the name of all the files that contain Vacation2010 with the same name, but with December instead of Vacation2010.

If you copy and paste the code, you have to save the .bat in the same folder of the photos. If you want to save the script in another directory [E.G. you have a favorite folder for the utilities] you have to change the value of _dir with the path of the photos.

If you have to do the same work for other photos [or others files changig _ext] you have to change the value of _toEdit with the string you want to change [or erase] and the value of _with with the string you want to put instead of _toEdit [SET "_with=" if you simply want to erase the string specified in _toEdit].

If you have the coreutils package installed you can generally use readlink -f relative_file_name in order to retrieve the absolute one (with all symlinks resolved)

Another way (although essentially equivalent to the new ArrayList(Arrays.asList(array)) solution performance-wise:

Collections.addAll(arraylist, array);

I have encountered the same problem and tried to change the ADB connection timeout. That did not work. I switched between my PC's USB ports (front -> back) and it fixed the problem!!!

Let's say we have a single byte:

0110110

Applying a single left bitshift gets us:

1101100

The leftmost zero was shifted out of the byte, and a new zero was appended to the right end of the byte.

The bits don't rollover; they are discarded. That means if you left shift 1101100 and then right shift it, you won't get the same result back.

Shifting left by N is equivalent to multiplying by 2^N.

Shifting right by N is (if you are using ones' complement) is the equivalent of dividing by 2^N and rounding to zero.

Bitshifting can be used for insanely fast multiplication and division, provided you are working with a power of 2. Almost all low-level graphics routines use bitshifting.

For example, way back in the olden days, we used mode 13h (320x200 256 colors) for games. In Mode 13h, the video memory was laid out sequentially per pixel. That meant to calculate the location for a pixel, you would use the following math:

memoryOffset = (row * 320) + column

Now, back in that day and age, speed was critical, so we would use bitshifts to do this operation.

However, 320 is not a power of two, so to get around this we have to find out what is a power of two that added together makes 320:

(row * 320) = (row * 256) + (row * 64)

Now we can convert that into left shifts:

(row * 320) = (row << 8) + (row << 6)

For a final result of:

memoryOffset = ((row << 8) + (row << 6)) + column

Now we get the same offset as before, except instead of an expensive multiplication operation, we use the two bitshifts...in x86 it would be something like this (note, it's been forever since I've done assembly (editor's note: corrected a couple mistakes and added a 32-bit example)):

mov ax, 320; 2 cycles
mul word [row]; 22 CPU Cycles
mov di,ax; 2 cycles
add di, [column]; 2 cycles
; di = [row]*320 + [column]

; 16-bit addressing mode limitations:
; [di] is a valid addressing mode, but [ax] isn't, otherwise we could skip the last mov

Total: 28 cycles on whatever ancient CPU had these timings.

Vrs

mov ax, [row]; 2 cycles
mov di, ax; 2
shl ax, 6;  2
shl di, 8;  2
add di, ax; 2    (320 = 256+64)
add di, [column]; 2
; di = [row]*(256+64) + [column]

12 cycles on the same ancient CPU.

Yes, we would work this hard to shave off 16 CPU cycles.

In 32 or 64-bit mode, both versions get a lot shorter and faster. Modern out-of-order execution CPUs like Intel Skylake (see http://agner.org/optimize/) have very fast hardware multiply (low latency and high throughput), so the gain is much smaller. AMD Bulldozer-family is a bit slower, especially for 64-bit multiply. On Intel CPUs, and AMD Ryzen, two shifts are slightly lower latency but more instructions than a multiply (which may lead to lower throughput):

imul edi, [row], 320    ; 3 cycle latency from [row] being ready
add  edi, [column]      ; 1 cycle latency (from [column] and edi being ready).
; edi = [row]*(256+64) + [column],  in 4 cycles from [row] being ready.

vs.

mov edi, [row]
shl edi, 6               ; row*64.   1 cycle latency
lea edi, [edi + edi*4]   ; row*(64 + 64*4).  1 cycle latency
add edi, [column]        ; 1 cycle latency from edi and [column] both being ready
; edi = [row]*(256+64) + [column],  in 3 cycles from [row] being ready.

Compilers will do this for you: See how GCC, Clang, and Microsoft Visual C++ all use shift+lea when optimizing return 320*row + col;.

The most interesting thing to note here is that x86 has a shift-and-add instruction (LEA) that can do small left shifts and add at the same time, with the performance as an add instruction. ARM is even more powerful: one operand of any instruction can be left or right shifted for free. So scaling by a compile-time-constant that's known to be a power-of-2 can be even more efficient than a multiply.

OK, back in the modern days... something more useful now would be to use bitshifting to store two 8-bit values in a 16-bit integer. For example, in C#:

// Byte1: 11110000
// Byte2: 00001111

Int16 value = ((byte)(Byte1 >> 8) | Byte2));

// value = 000011111110000;

In C++, compilers should do this for you if you used a struct with two 8-bit members, but in practice they don't always.

You're trying to concatenate a string and an integer, which is incorrect.

Change print(numlist.pop(2)+" has been removed") to any of these:

Explicit int to str conversion:

print(str(numlist.pop(2)) + " has been removed")

Use , instead of +:

print(numlist.pop(2), "has been removed")

String formatting:

print("{} has been removed".format(numlist.pop(2)))

It's always problematic and often misleading to try and translate constructs and concepts between languages. Casting is no exception. Particularly because Java is a dynamic language and C++ is somewhat different.

All casting in Java, no matter how you do it, is done at runtime. Type information is held at runtime. C++ is a bit more of a mix. You can cast a struct in C++ to another and it's merely a reinterpretation of the bytes that represent those structs. Java doesn't work that way.

Also generics in Java and C++ are vastly different. Don't concern yourself overly with how you do C++ things in Java. You need to learn how to do things the Java way.

Procedural generation only means that code is used to generate the data instead of it being hand made. For example if you want to generate a forest with various trees you are not going to design each tree by hand, thus coding is more efficient to generate the variations. It could be the generation of the tree graphics, size, structure, placement ...

In general there is some kind of interation with a few rules, in addition to that you can add some randomness and logic of your own, combine all of these techniques ... Anything somewhat chaotic but not too chaotic can yield interesting results.

Assuming you must have two tables for the two employee types for some reason, I'll extend on vmarquez's answer:

Schema:

employees_ce (id, name)
employees_sn (id, name)
deductions (id, parentId, parentType, name)

Data in deductions:

deductions table
id      parentId      parentType      name
1       1             ce              gold
2       1             sn              silver
3       2             sn              wood
...

This would allow you to have deductions point to any other table in your schema. This kind of relation isn't supported by database-level constraints, IIRC so you'll have to make sure your App manages the constraint properly (which makes it more cumbersome if you have several different Apps/services hitting the same database).

Solution for swift 4.2

So, if you just want to answer the question whether the dictionary contains the key, ask:

let keyExists = dict[key] != nil

If you want the value and you know the dictionary contains the key, say:

let val = dict[key]!

But if, as usually happens, you don't know it contains the key - you want to fetch it and use it, but only if it exists - then use something like if let:

if let val = dict[key] {
    // now val is not nil and the Optional has been unwrapped, so use it
}

Yes it stops execution so this is generally preferable to HAVING COUNT(*) > 0 which often won't.

With EXISTS if you look at the execution plan you will see that the actual number of rows coming out of table1 will not be more than 1 irrespective of number of matching records.

In some circumstances SQL Server can convert the tree for the COUNT query to the same as the one for EXISTS during the simplification phase (with a semi join and no aggregate operator in sight) an example of that is discussed in the comments here.

For more complicated sub trees than shown in the question you may occasionally find the COUNT performs better than EXISTS however. Because the semi join needs only retrieve one row from the sub tree this can encourage a plan with nested loops for that part of the tree - which may not work out optimal in practice.

Since C++14 you can use two real string literals:

const string hello = "Hello"s;

const string message = hello + ",world"s + "!"s;

or

const string exclam = "!"s;

const string message = "Hello"s + ",world"s + exclam;

I was getting exactly that error too: Connection reset by peer. The exception was being raised by Spring's REST template upon running the postForObject() method. For me the problem was too long HTTP URL request. So first check whether the URL produced is what it should be and, if your server really should be able to handle requests of that length, simply go to server's configuration and raise the default allowed length of URL requests.

That solved the problem for me, but be aware: the application might not run on some internet browsers, especially old ones, as they have fixed max length of URL requests.

Hope it helps...

...In short:

string[] arr = "This is a sentence".Split(new string[] { "is" }, StringSplitOptions.None);

EDIT : 31/10/2017

The same code/approach will work for Asp.Net Core 2.0 as well. The major difference is, In asp.net core, both web api controllers and Mvc controllers are merged together to single controller model. So your return type might be IActionResult or one of it's implementation (Ex :OkObjectResult)

Use

contentType:"application/json"

You need to use JSON.stringify method to convert it to JSON string when you send it,

And the model binder will bind the json data to your class object.

The below code will work fine (tested)

$(function () {
    var customer = {contact_name :"Scott",company_name:"HP"};
    $.ajax({
        type: "POST",
        data :JSON.stringify(customer),
        url: "api/Customer",
        contentType: "application/json"
    });
});

Result

contentType property tells the server that we are sending the data in JSON format. Since we sent a JSON data structure,model binding will happen properly.

If you inspect the ajax request's headers, you can see that the Content-Type value is set as application/json.

If you do not specify contentType explicitly, It will use the default content type which is application/x-www-form-urlencoded;

Posting a complex object

Let's say you have a complex view model class as your web api action method parameter like this

public class CreateUserViewModel
{
   public int Id {set;get;}
   public string Name {set;get;}  
   public List<TagViewModel> Tags {set;get;}
}
public class TagViewModel
{
  public int Id {set;get;}
  public string Code {set;get;}
}

and your web api end point is like

public class ProductController : Controller
{
    [HttpPost]
    public CreateUserViewModel Save([FromBody] CreateUserViewModel m)
    {
        // I am just returning the posted model as it is. 
        // You may do other stuff and return different response.
        // Ex : missileService.LaunchMissile(m);
        return m;
    }
}

At the time of this writing, ASP.NET MVC 6 is the latest stable version and in MVC6, Both Web api controllers and MVC controllers are inheriting from Microsoft.AspNet.Mvc.Controller base class.

To send data to the method from client side, the below code should work fine

//Build an object which matches the structure of our view model class
var model = {
    Name: "Shyju",
    Id: 123,
    Tags: [{ Id: 12, Code: "C" }, { Id: 33, Code: "Swift" }]
};

$.ajax({
    type: "POST",
    data: JSON.stringify(model),
    url: "../product/save",
    contentType: "application/json"
}).done(function(res) {       
    console.log('res', res);
    // Do something with the result :)
});

Model binding works for some properties, but not all ! Why ?

If you do not decorate the web api method parameter with [FromBody] attribute

[HttpPost]
public CreateUserViewModel Save(CreateUserViewModel m)
{
    return m;
}

And send the model(raw javascript object, not in JSON format) without specifying the contentType property value

$.ajax({
    type: "POST",
    data: model,
    url: "../product/save"
}).done(function (res) {
     console.log('res', res);
});

Model binding will work for the flat properties on the model, not the properties where the type is complex/another type. In our case, Id and Name properties will be properly bound to the parameter m, But the Tags property will be an empty list.

The same problem will occur if you are using the short version, $.post which will use the default Content-Type when sending the request.

$.post("../product/save", model, function (res) {
    //res contains the markup returned by the partial view
    console.log('res', res);
});

Current versions of Windows use Powershell as the default shell, so use:

$env:NODE_ENV="production"

Per @jsalonen's answer below. If you're in CMD (which is no longer maintained), use

set NODE_ENV=production

This should be executed in the command prompt where you intend to run your Node.js application.

The above line would set the environment variable NODE_ENV for the command prompt where you execute the command.

To set environment variables globally so they persist beyond just the single command prompt, you can find the tool from System in Control Panel (or by typing 'environment' into the search box in the start menu).

Use the URI class.

Create a new URI with your existing String to "break it up" to parts, and instantiate another one to assemble the modified url:

URI u = new URI("http://[email protected]&name=John#fragment");

// Modify the query: append your new parameter
StringBuilder sb = new StringBuilder(u.getQuery() == null ? "" : u.getQuery());
if (sb.length() > 0)
    sb.append('&');
sb.append(URLEncoder.encode("paramName", "UTF-8"));
sb.append('=');
sb.append(URLEncoder.encode("paramValue", "UTF-8"));

// Build the new url with the modified query:
URI u2 = new URI(u.getScheme(), u.getAuthority(), u.getPath(),
    sb.toString(), u.getFragment());

You can even use

window.open('https://support.wwf.org.uk', "_blank") || window.location.replace('https://support.wwf.org.uk');

This will open it on the same tab if the pop-up is blocked.
