Isodate seems to have the most complete support.

The problem was the table width. I had used width: 100% for the table. The table columns are adjusted automatically after removing the width tag.

This removes html code or php if you supplement it. Allows you to add trailing slash and it come up as well as the url without the trailing slash all bypassing the 404 code. Plus a little added security.

If your input was structured as XML, you could use the importXML function. (More info here at quirksmode).

If it isn't XML, and there isn't an equivalent function for importing plain text, then you could open it in a hidden iframe and then read the contents from there.

The default modifier is package. Only code in the same package will be able to invoke this constructor.

From the DotNetZip help file, http://dotnetzip.codeplex.com/releases/

using (ZipFile zip = new ZipFile())
{
   zip.UseUnicodeAsNecessary= true;  // utf-8
   zip.AddDirectory(@"MyDocuments\ProjectX");
   zip.Comment = "This zip was created at " + System.DateTime.Now.ToString("G") ; 
   zip.Save(pathToSaveZipFile);
}

My solution:

Create a function script that is called earlier than all other functions without passing any arguments to it, like this:

! /bin/bash

function init(){ ORIGOPT= "- $@ -" }

Afer that, you can call init and use the ORIGOPT var as needed,as a plus, I always assign a new var and copy the contents of ORIGOPT in my new functions, that way you can keep yourself assured nobody is going to touch it or change it.

I added spaces and dashes to make it easier to parse it with 'sed -E' also bash will not pass it as reference and make ORIGOPT grow as functions are called with more arguments.

You can edit style with pure Javascript. No library needed, supported by all browsers except IE where you need to set to '' instead of null (see comments).

var element = document.getElementById('sample_id');

element.style.width = null;
element.style.height = null;

For more information, you can refer to HTMLElement.style documentation on MDN.

 HTML link click

// Route

Route::group(['middleware'=>['auth']], function(){
    Route::get('file-download/{id}', 'PostController@downloadproject')->name('project.download');
});

public function downloadproject($id) {

        $book_cover = Post::where('id', $id)->firstOrFail();
        $path = public_path(). '/storage/uploads/zip/'. $book_cover->zip;
        return response()->download($path, $book_cover
            ->original_filename, ['Content-Type' => $book_cover->mime]);

    }

From PEP 8 -- Style Guide for Python Code:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. Long lines can be broken over multiple lines by wrapping expressions in parentheses. These should be used in preference to using a backslash for line continuation.

Backslashes may still be appropriate at times. For example, long, multiple with-statements cannot use implicit continuation, so backslashes are acceptable:

with open('/path/to/some/file/you/want/to/read') as file_1, \
        open('/path/to/some/file/being/written', 'w') as file_2:
    file_2.write(file_1.read())

Another such case is with assert statements.

Make sure to indent the continued line appropriately. The preferred place to break around a binary operator is after the operator, not before it. Some examples:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

PEP8 now recommends the opposite convention (for breaking at binary operations) used by mathematicians and their publishers to improve readability.

Donald Knuth's style of breaking before a binary operator aligns operators vertically, thus reducing the eye's workload when determining which items are added and subtracted.

From PEP8: Should a line break before or after a binary operator?:

Donald Knuth explains the traditional rule in his Computers and Typesetting series: "Although formulas within a paragraph always break after binary operations and relations, displayed formulas always break before binary operations"[3].

Following the tradition from mathematics usually results in more readable code:

# Yes: easy to match operators with operands
income = (gross_wages
          + taxable_interest
          + (dividends - qualified_dividends)
          - ira_deduction
          - student_loan_interest)

In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. For new code Knuth's style is suggested.

Spread operator

The spread operator allows an expression to be expanded in places where multiple arguments (for function calls) or multiple elements (for array literals) are expected.

ECMAScript ES6 added a new operator that lets you do this in a more practical way: ...Spread Operator.

Example without using the apply method:

function a(...args){_x000D_
  b(...args);_x000D_
  b(6, ...args, 8) // You can even add more elements_x000D_
}_x000D_
function b(){_x000D_
  console.log(arguments)_x000D_
}_x000D_
_x000D_
a(1, 2, 3)

Note This snippet returns a syntax error if your browser still uses ES5.

^{Editor's note: Since the snippet uses console.log(), you must open your browser's JS console to see the result - there will be no in-page result.}

It will display this result:

In short, the spread operator can be used for different purposes if you're using arrays, so it can also be used for function arguments, you can see a similar example explained in the official docs: Rest parameters

There were a few ways I found to do this:

• Firefox: Add Exception -> Get Certificat -> View -> Details -> Export...
• KeyMan (http://www.alphaworks.ibm.com/tech/keyman) You can get SSL cert directly from the File -> Import menu
• InstallCert (Code by Andreas Sterbenz)

    java InstallCert [host]:[port] 
    keytool -exportcert -keystore jssecacerts -storepass changeit -file output.cert
    keytool -importcert -keystore [DESTINATION_KEYSTORE] -file output.cert

You want in page A to know the URL of page B?

Or to know in page B the URL of page A?

In Page B: document.referrer if set. As already shown here: How to get the previous URL in JavaScript?

In page A you would need to read a cookie or local/sessionStorage you set in page B, assuming the same domains

If you are not limiting yourself to the standard library, I like psutil for this.

For instance to find all "python" processes:

>>> import psutil
>>> [p.info for p in psutil.process_iter(attrs=['pid', 'name']) if 'python' in p.info['name']]
[{'name': 'python3', 'pid': 21947},
 {'name': 'python', 'pid': 23835}]

When you click on the image you'll get the alert:

<img src="logo1.jpg" onClick='alert("Hello World!")'/>

if this is what you want.

you can convert any SVG to a component and make it reusable.

In PCRE \R matches \n, \r and \r\n.

My .bash_profile file and how I used grep:

If the PATH environment variable includes my two bin directories, don't append them,

# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

U=~/.local.bin:~/bin

if ! echo "$PATH" | grep -q "home"; then
    export PATH=$PATH:${U}

Android resources have pretty good HTML markup support
The below HTML elements are supported:

Bold: <b>, <em>
Italic: <i>, <cite>, <dfn>
25% larger text: <big>
20% smaller text: <small>
Setting font properties: <font face=”font_family“ color=”hex_color”>. Examples of possible font families include monospace, serif, and sans_serif.
Setting a monospace font family: <tt>
Strikethrough: <s>, <strike>, <del>
Underline: <u>
Superscript: <sup>
Subscript: <sub>
Bullet points: <ul>, <li>
Line breaks: <br>
Division: <div>
CSS style: <span style=”color|background_color|text-decoration”>
Paragraphs: <p dir=”rtl | ltr” style=”…”>

Note however that it's not rendered in android studio layouts preview. Last tested on Android Studio 3.3.1

For example, the Strikethrough will look like that:

<string name="cost"><strike>$10</strike> $5 a month</string>

In case of complex ProgressBar like this,

use ClipDrawable.

NOTE : I've not used ProgressBar here in this example. I've achieved this using ClipDrawable by clipping image with Animation.

A Drawable that clips another Drawable based on this Drawable's current level value. You can control how much the child Drawable gets clipped in width and height based on the level, as well as a gravity to control where it is placed in its overall container. Most often used to implement things like progress bars, by increasing the drawable's level with setLevel().

NOTE : The drawable is clipped completely and not visible when the level is 0 and fully revealed when the level is 10,000.

I've used this two images to make this CustomProgressBar.

You should create a pseudo-random number generator only once:

Dim Generator As System.Random = New System.Random()

Then, if an integer suffices for your needs, you can use:

Public Function GetRandom(myGenerator As System.Random, ByVal Min As Integer, ByVal Max As Integer) As Integer
'min is inclusive, max is exclusive (dah!)
Return myGenerator.Next(Min, Max + 1)
End Function

as many times as you like. Using the wrapper function is justified only because the maximum value is exclusive - I know that the random numbers work this way but the definition of .Next is confusing.

Creating a generator every time you need a number is in my opinion wrong; the pseudo-random numbers do not work this way.

First, you get the problem with initialization which has been discussed in the other replies. If you initialize once, you do not have this problem.

Second, I am not at all certain that you get a valid sequence of random numbers; rather, you get a collection of the first number of multiple different sequences which are seeded automatically based on computer time. I am not certain that these numbers will pass the tests that confirm the randomness of the sequence.

If you have a array of objects you can do like this:

myArrayObjects = myArrayObjects.sort(function(a, b) {
  return a.name.localeCompare(b.name, undefined, {
    numeric: true,
    sensitivity: 'base'
  });
});

var myArrayObjects = [{_x000D_
    "id": 1,_x000D_
    "name": "1 example"_x000D_
  },_x000D_
  {_x000D_
    "id": 2,_x000D_
    "name": "100 example"_x000D_
  },_x000D_
  {_x000D_
    "id": 3,_x000D_
    "name": "12 example"_x000D_
  },_x000D_
  {_x000D_
    "id": 4,_x000D_
    "name": "5 example"_x000D_
  },_x000D_
_x000D_
]_x000D_
_x000D_
myArrayObjects = myArrayObjects.sort(function(a, b) {_x000D_
  return a.name.localeCompare(b.name, undefined, {_x000D_
    numeric: true,_x000D_
    sensitivity: 'base'_x000D_
  });_x000D_
});_x000D_
console.log(myArrayObjects);

Is something as simple as the following not good enough?

return abs(f1 - f2) <= allowed_error

You should read collections framework tutorial first of all.

But to answer your question this is how you should do it:

ArrayList<String> strings = new ArrayList<String>();
strings.add("String1");
strings.add("String2");

// To access a specific element:
System.out.println(strings.get(1));
// To loop through and print all of the elements:
for (String element : strings) {
    System.out.println(element);
}

You probably need to chdir to the correct directory before calling the script. This way you can ensure what directory your script is "in" before calling the shell command.

$old_path = getcwd();
chdir('/my/path/');
$output = shell_exec('./script.sh var1 var2');
chdir($old_path);

Another alternative:

$('option:selected', $('#mySelectParent')).removeAttr("selected");

Hope it helps

Assuming you have the necessary privileges to run svnadmin, you need to use the dump and load commands.

From what I understand you want to use a div that inherits from no class but yours. As mentioned in the previous reply you cannot completely reset a div inheritance. However, what worked for me with that issue was to use another element - one that is not frequent and certainly not used in the current html page. A good example, is to use instead of then customize it to look just like your ideal would.

area { background-color : red; }

There are three ways of doing this.

let say you have a list of integers

my_list = [100,200,300]

1. "-".join(str(n) for n in my_list)
2. "-".join([str(n) for n in my_list])
3. "-".join(map(str, my_list))

However as stated in the example of timeit on python website at https://docs.python.org/2/library/timeit.html using a map is faster. So I would recommend you using "-".join(map(str, my_list))

They're called indexed views in SQL Server - read these white papers for more background:

• Creating an Indexed View
• Improving Performance with SQL Server 2008 Indexed Views

Basically, all you need to do is:

• create a regular view
• create a clustered index on that view

and you're done!

The tricky part is: the view has to satisfy quite a number of constraints and limitations - those are outlined in the white paper. If you do this, that's all there is. The view is being updated automatically, no maintenance needed.

If you're not sure your input is going to be a Numpy array, you can use asarray with dtype=int instead of astype:

>>> np.asarray([1,2,3,4], dtype=int)
array([1, 2, 3, 4])

If the input array already has the correct dtype, asarray avoids the array copy while astype does not (unless you specify copy=False):

>>> a = np.array([1,2,3,4])
>>> a is np.asarray(a)  # no copy :)
True
>>> a is a.astype(int)  # copy :(
False
>>> a is a.astype(int, copy=False)  # no copy :)
True

Try width:inherit to make the image take the width of it's container <div>. It will stretch/shrink it's height to maintain proportion. Don't set the height in the <div>, it will size to fit the image height.

img {
    width:inherit;
}

.item {
    border:1px solid pink;
    width: 120px;
    float: left;
    margin: 3px;
    padding: 3px;
}

Unless there is a single row in the ASSIGNMENT table and ASSIGNMENT_20081120 is a local PL/SQL variable of type ASSIGNMENT%ROWTYPE, this is not what you want.

CREATE TABLE assignment_20081120

Here is a simpler solution to list all files in a directory and to download it.

In your index.php file

<?php
$dir = "./";

$allFiles = scandir($dir);
$files = array_diff($allFiles, array('.', '..')); // To remove . and .. 

foreach($files as $file){
     echo "<a href='download.php?file=".$file."'>".$file."</a><br>";
}

The scandir() function list all files and directories inside the specified path. It works with both PHP 5 and PHP 7.

Now in the download.php

<?php
$filename = basename($_GET['file']);
// Specify file path.
$path = ''; // '/uplods/'
$download_file =  $path.$filename;

if(!empty($filename)){
    // Check file is exists on given path.
    if(file_exists($download_file))
    {
      header('Content-Disposition: attachment; filename=' . $filename);  
      readfile($download_file); 
      exit;
    }
    else
    {
      echo 'File does not exists on given path';
    }
 }

Yes, there is a difference. Html.ActionLink generates an <a href=".."></a> tag whereas Url.Action returns only an url.

For example:

@Html.ActionLink("link text", "someaction", "somecontroller", new { id = "123" }, null)

generates:

<a href="/somecontroller/someaction/123">link text</a>

and Url.Action("someaction", "somecontroller", new { id = "123" }) generates:

/somecontroller/someaction/123

There is also Html.Action which executes a child controller action.

The main image manager in PIL is PIL's Image module.

from PIL import Image
import math

foo = Image.open("path\\to\\image.jpg")
x, y = foo.size
x2, y2 = math.floor(x-50), math.floor(y-20)
foo = foo.resize((x2,y2),Image.ANTIALIAS)
foo.save("path\\to\\save\\image_scaled.jpg",quality=95)

You can add optimize=True to the arguments of you want to decrease the size even more, but optimize only works for JPEG's and PNG's. For other image extensions, you could decrease the quality of the new saved image. You could change the size of the new image by just deleting a bit of code and defining the image size and you can only figure out how to do this if you look at the code carefully. I defined this size:

x, y = foo.size
x2, y2 = math.floor(x-50), math.floor(y-20)

just to show you what is (almost) normally done with horizontal images. For vertical images you might do:

x, y = foo.size
x2, y2 = math.floor(x-20), math.floor(y-50)

. Remember, you can still delete that bit of code and define a new size.

the above method did not work for me for a for loop, where I wanted to transfer data from a 2D array to a new array under an if the condition. This method would work

a_2d_list = [[1, 2], [3, 4]]
a_2d_list.append([5, 6])
print(a_2d_list)

OUTPUT - [[1, 2], [3, 4], [5, 6]]

Set the CSS position: relative; on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:

position: absolute;
bottom: 0;
right: 0;

If you need to space the text farther away from the edge, you could change 0 to 2px or similar.

In the documentaion http://contactform7.com/text-fields/#textarea

[textarea* message id:contact-message 10x2 placeholder "Your Message"]

The DESCRIBE command is your friend. You can describe one keyspace, list keyspaces, one table or list all tables in keyspace, the cluster and much more. You can get the full idea by typing

Connected to mscluster at 127.0.0.1:9042. [cqlsh 5.0.1 | Cassandra 3.8 | CQL spec 3.4.2 | Native protocol v4] Use HELP for help.

cqlsh> HELP DESCRIBE

    DESCRIBE [cqlsh only]

    (DESC may be used as a shorthand.)

      Outputs information about the connected Cassandra cluster, or about
      the data objects stored in the cluster. Use in one of the following ways:...<omitted for brevity>

• DESCRIBE <your key space name> - describes the command used to create keyspace

cqlsh> DESCRIBE testkeyspace;

CREATE KEYSPACE testkeyspace WITH replication = {'class':'SimpleStrategy', 'replication_factor': '3'} AND durable_writes = true;

• DESCRIBE keyspaces - lists all keyspaces

cqlsh> DESCRIBE KEYSPACES

The input.files attribute is an HTML5 feature. That's why some browsers din't return anything. Simply add a fallback to the plain old input.value (string) if files doesn't exist.

Just do a require('./yourfile.js');

Declare all the variables that you want outside access as global variables. So instead of

var a = "hello" it will be

GLOBAL.a="hello" or just

a = "hello"

This is obviously bad. You don't want to be polluting the global scope. Instead the suggest method is to export your functions/variables.

If you want the MVC pattern take a look at Geddy.

When I use a non-default modules in my scripts I call the function below. Beside the module name you can provide a minimum version.

# See https://www.powershellgallery.com/ for module and version info
Function Install-ModuleIfNotInstalled(
    [string] [Parameter(Mandatory = $true)] $moduleName,
    [string] $minimalVersion
) {
    $module = Get-Module -Name $moduleName -ListAvailable |`
        Where-Object { $null -eq $minimalVersion -or $minimalVersion -ge $_.Version } |`
        Select-Object -Last 1
    if ($null -ne $module) {
         Write-Verbose ('Module {0} (v{1}) is available.' -f $moduleName, $module.Version)
    }
    else {
        Import-Module -Name 'PowershellGet'
        $installedModule = Get-InstalledModule -Name $moduleName -ErrorAction SilentlyContinue
        if ($null -ne $installedModule) {
            Write-Verbose ('Module [{0}] (v {1}) is installed.' -f $moduleName, $installedModule.Version)
        }
        if ($null -eq $installedModule -or ($null -ne $minimalVersion -and $installedModule.Version -lt $minimalVersion)) {
            Write-Verbose ('Module {0} min.vers {1}: not installed; check if nuget v2.8.5.201 or later is installed.' -f $moduleName, $minimalVersion)
            #First check if package provider NuGet is installed. Incase an older version is installed the required version is installed explicitly
            if ((Get-PackageProvider -Name NuGet -Force).Version -lt '2.8.5.201') {
                Write-Warning ('Module {0} min.vers {1}: Install nuget!' -f $moduleName, $minimalVersion)
                Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Scope CurrentUser -Force
            }        
            $optionalArgs = New-Object -TypeName Hashtable
            if ($null -ne $minimalVersion) {
                $optionalArgs['RequiredVersion'] = $minimalVersion
            }  
            Write-Warning ('Install module {0} (version [{1}]) within scope of the current user.' -f $moduleName, $minimalVersion)
            Install-Module -Name $moduleName @optionalArgs -Scope CurrentUser -Force -Verbose
        } 
    }
}

usage example:

Install-ModuleIfNotInstalled 'CosmosDB' '2.1.3.528'

Please let me known if it's usefull (or not)

If you already have a stream and know the format, you can use something like this:

static ImageSource PngStreamToImageSource (Stream pngStream) {
    var decoder = new PngBitmapDecoder(pngStream,
        BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
    return decoder.Frames[0];
}

May be by:-

    for(Row row : sheet) {          
        for(Cell cell : row) {              
            System.out.print(cell.getStringCellValue());

        }
    }       

For specific type of cell you can try:

switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
    cellValue = cell.getStringCellValue();
    break;

case Cell.CELL_TYPE_FORMULA:
    cellValue = cell.getCellFormula();
    break;

case Cell.CELL_TYPE_NUMERIC:
    if (DateUtil.isCellDateFormatted(cell)) {
        cellValue = cell.getDateCellValue().toString();
    } else {
        cellValue = Double.toString(cell.getNumericCellValue());
    }
    break;

case Cell.CELL_TYPE_BLANK:
    cellValue = "";
    break;

case Cell.CELL_TYPE_BOOLEAN:
    cellValue = Boolean.toString(cell.getBooleanCellValue());
    break;

}

just use this at the end of your button click event

protected void btnAddButton_Click(object sender, EventArgs e)
{
   ... save data routin 
     Response.Redirect(Request.Url.AbsoluteUri);
}

With RxJS 5.5+, the catch operator is now deprecated. You should now use the catchError operator in conjunction with pipe.

RxJS v5.5.2 is the default dependency version for Angular 5.

For each RxJS Operator you import, including catchError you should now import from 'rxjs/operators' and use the pipe operator.

Example of catching error for an Http request Observable

import { Observable } from 'rxjs';
import { catchError } from 'rxjs/operators';
...

export class ExampleClass {
  constructor(private http: HttpClient) {
    this.http.request(method, url, options).pipe(
      catchError((err: HttpErrorResponse) => {
        ...
      }
    )
  }
  ...
}

Notice here that catch is replaced with catchError and the pipe operator is used to compose the operators in similar manner to what you're used to with dot-chaining.

See the rxjs documentation on pipable (previously known as lettable) operators for more info.

FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.

What seems to be confusing you is the fact that functions that are declared to be pass-by-reference (using the &) aren't called using actual addresses, i.e. &a.

The simple answer is that declaring a function as pass-by-reference:

void foo(int& x);

is all we need. It's then passed by reference automatically.

You now call this function like so:

int y = 5;
foo(y);

and y will be passed by reference.

You could also do it like this (but why would you? The mantra is: Use references when possible, pointers when needed) :

#include <iostream>
using namespace std;

class CDummy {
public:
    int isitme (CDummy* param);
};


int CDummy::isitme (CDummy* param)
{
    if (param == this) return true;
    else return false;
}

int main () {
    CDummy a;
    CDummy* b = &a;             // assigning address of a to b
    if ( b->isitme(&a) )        // Called with &a (address of a) instead of a
        cout << "yes, &a is b";
    return 0;
}

Output:

yes, &a is b

Need to merge the properties in object. For Example,

const boxStyle = {
  width : "50px",
  height : "50px"
};
const redBackground = {
  ...boxStyle,
  background: "red",
};
const blueBackground = {
  ...boxStyle,
  background: "blue",
}




 <div style={redBackground}></div>
 <div style={blueBackground}></div>

Please post your Model Class.

To check the errors in your ModelState use the following code:

var errors = ModelState
    .Where(x => x.Value.Errors.Count > 0)
    .Select(x => new { x.Key, x.Value.Errors })
    .ToArray();

OR: You can also use

var errors = ModelState.Values.SelectMany(v => v.Errors);

Place a break point at the above line and see what are the errors in your ModelState.

The recommended approach is to use fill constructor to initialize a two-dimensional vector with a given default value :

std::vector<std::vector<int>> fog(M, std::vector<int>(N, default_value));

where, M and N are dimensions for your 2D vector.

You need to start your Apache Server normally you should have an xampp icon in the info-section from the taskbar, with this tool you can start the apache server as wel as the mysql database (if you need it)

Use the string.substring(from, to) API. In your case, use string.substring(0,8).

Shallow copy with copy.copy()

#!/usr/bin/env python3

import copy

class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]

# It copies.
c = C()
d = copy.copy(c)
d.x = [3]
assert c.x == [1]
assert d.x == [3]

# It's shallow.
c = C()
d = copy.copy(c)
d.x[0] = 3
assert c.x == [3]
assert d.x == [3]

Deep copy with copy.deepcopy()

#!/usr/bin/env python3
import copy
class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]
c = C()
d = copy.deepcopy(c)
d.x[0] = 3
assert c.x == [1]
assert d.x == [3]

Documentation: https://docs.python.org/3/library/copy.html

Tested on Python 3.6.5.

Your code for setting value for hidden input is correct. Here is the example. Maybe you have some conditions in your if statements that are not allowing your scripts to execute.

I solved this question with solution below

  import org.joda.time.LocalDate;
  Date myDate = new Date();
  LocalDate localDate = LocalDate.fromDateFields(myDate);
  System.out.println("My date using Date" Nov 18 11:23:33 BRST 2016);
  System.out.println("My date using joda.time LocalTime" 2016-11-18);

In this case localDate print your date in this format "yyyy-MM-dd"

Global events are also deprecated.

Maybe an interesting point to make, is the difference between priorities between both.

As far as I can tell, the ng-if directive has one of the highest (if not the highest) priority of all Angular directives. Which means: it will run FIRST before all other, lower prioritised, directives. The fact that it runs FIRST, means that effectively, the element is removed before any inner directives are processed. Or at least: that's what I make of it.

I observerd and used this in the UI I'm building for my current customer. The entire UI is quite heavily packed, and it had ng-show and ng-hide all over it. Not to go into too much detail, but I built a generic component, which could be managed using JSON config, so I had to do some switching inside the template. There is an ng-repeat present, and inside the ng-repeat, a table is shown, which has a lot of ng-shows, ng-hides and even ng-switches present. They wanted to show at least 50 repeats in the list, which would result in more or less 1500-2000 directives to be resolved. I checked the code, and the Java backend + custom JS on the front would take about 150ms to process the data, and then Angular would chew some 2-3 seconds on it, before displaying. The customer did not complain, but I was appalled :-)

In my search, I stumbled across the ng-if directive. Now, maybe it's best to point out that at the point of conceiving this UI, there was no ng-if available. Because the ng-show and ng-hide had functions in them, which returned booleans, I could easily replace them all with ng-if. By doing so, all inner directives seemed to be no longer evaluated. That meant that I dropped back to about a third of all directives being evaluated, and thus, the UI speeded up to about 500ms - 1 sec loading time. (I have no way to determine exact seconds)

Do note: the fact that the directives are not evaluated, is an educated guess about what is happening underneath.

So, in my opinion: if you need the element to be present on the page (ie: for checking the element, or whatever), but simply be hidden, use ng-show/ng-hide. In all other cases, use ng-if.

FFMpeg can do this by seeking to the given timestamp and extracting exactly one frame as an image, see for instance:

ffmpeg -i input_file.mp4 -ss 01:23:45 -vframes 1 output.jpg

Let's explain the options:

-i input file           the path to the input file
-ss 01:23:45            seek the position to the specified timestamp
-vframes 1              only handle one video frame
output.jpg              output filename, should have a well-known extension

The -ss parameter accepts a value in the form HH:MM:SS[.xxx] or as a number in seconds. If you need a percentage, you need to compute the video duration beforehand.

In short

To get this to work also with NCrunch I had to add the Interop.dll versions provided with the NuGet package as additional files in NCrunch configuration.

My case

I had a C# solution with one project directly depending on SQLite (a helper library) and a unit test project that used this helper library. I had installed System.Data.SQLite.Core version 1.0.97.0 as a NuGet package.

In my case the workaround provided by Marin got it working in Visual Studio and in CI as well. However this would still provide errors in NCrunch.

In NCrunch configuration I added the following path in "Additional files to include" under the unit test projects settings:

..\packages\System.Data.SQLite.Core.1.0.97.0\build\net45\**.dll

Entire request and response is encrypted, including URL.

Note that when you use a HTTP Proxy, it knows the address (domain) of the target server, but doesn't know the requested path on this server (i.e. request and response are always encrypted).

You can check this way too

<c:if test="${theBooleanVariable ne true}">It's false!</c:if>

What is blob url? Why it is used?

BLOB is just byte sequence. Browser recognize it as byte stream. It is used to get byte stream from source.

A Blob object represents a file-like object of immutable, raw data. Blobs represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.

Can i make my own blob url on a server?

Yes you can there are serveral ways to do so for example try http://php.net/manual/en/function.ibase-blob-echo.php

Read more on

• https://developer.mozilla.org/pl/docs/Web/API/Blob
• http://www.w3.org/TR/FileAPI/#dfn-Blob
• https://url.spec.whatwg.org/#urls

Because python 3 print() function allows end="" definition, that satisfies the majority of issues.

In my case, I wanted to PrettyPrint and was frustrated that this module wasn't similarly updated. So i made it do what i wanted:

from pprint import PrettyPrinter

class CommaEndingPrettyPrinter(PrettyPrinter):
    def pprint(self, object):
        self._format(object, self._stream, 0, 0, {}, 0)
        # this is where to tell it what you want instead of the default "\n"
        self._stream.write(",\n")

def comma_ending_prettyprint(object, stream=None, indent=1, width=80, depth=None):
    """Pretty-print a Python object to a stream [default is sys.stdout] with a comma at the end."""
    printer = CommaEndingPrettyPrinter(
        stream=stream, indent=indent, width=width, depth=depth)
    printer.pprint(object)

Now, when I do:

comma_ending_prettyprint(row, stream=outfile)

I get what I wanted (substitute what you want -- Your Mileage May Vary)

You can do it with:

dotnet ef migrations remove

Warning

Take care not to remove any migrations which are already applied to production databases. Not doing so will prevent you from being able to revert it, and may break the assumptions made by subsequent migrations.

Download mingw-get and simply issue:

mingw-get install gcc.

See the Getting Started page.

if you don'y want to import any files you can use this:

with open("Test1.txt", "r") as File1:
St = (' '.join(format(ord(x), 'b') for x in File1.read()))
StrList = St.split(" ")

to convert a text file to binary.

and you can use this to convert it back to string:

StrOrgList = StrOrgMsg.split(" ")


for StrValue in StrOrgList:
    if(StrValue != ""):
        StrMsg += chr(int(str(StrValue),2))
print(StrMsg)

hope that is helpful, i've used this with some custom encryption to send over TCP.

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

Rotating a vector 90 degrees is particularily simple.

(x, y) rotated 90 degrees around (0, 0) is (-y, x).

If you want to rotate clockwise, you simply do it the other way around, getting (y, -x).

Some receivers expect EOL sequence, which is typically two characters \r\n, so try in your code replace the line

unsigned char cmd[] = {'I', 'N', 'I', 'T', ' ', '\r', '\0'};

with

unsigned char cmd[] = "INIT\r\n";

BTW, the above way is probably more efficient. There is no need to quote every character.

In certain circumstances you may want to only pass down the environment variables your subprocess needs, but I think you've got the right idea in general (that's how I do it too).

In your case you would use two case staements, one for each value you want returned.

You need to change source to viewmodel object:

Had a similar problem, fixed it by calling python3 instead of python, my modules were in Python3.5.

The following command installs ruby gem for ubuntu:

Assuming you have an ArrayList that contains characters, you could do this:

List<Character> list = new ArrayList<Character>();
list.addAll(Arrays.asList('+', '-', '*', '^'));

Choose some columns to coerce to factors:

cols <- c("A", "C", "D", "H")

Use lapply() to coerce and replace the chosen columns:

data[cols] <- lapply(data[cols], factor)  ## as.factor() could also be used

Check the result:

sapply(data, class)
#        A         B         C         D         E         F         G 
# "factor" "integer"  "factor"  "factor" "integer" "integer" "integer"

To add to Mehrdad answer ,

namespace Math
{
    class Matrix
    {
       public:

       [...]


    }   
    std::ostream& operator<< (std::ostream& stream, const Math::Matrix& matrix);
}

In your implementation

std::ostream& operator<<(std::ostream& stream, 
                     const Math::Matrix& matrix) {
    matrix.print(stream); //assuming you define print for matrix 
    return stream;
 }

Online converter, nice way and time saver ;)

Simple solution:

<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>

This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.

If you want to do this often, you can create a keybindings file in your Library to map it to a key combination.

In ~/Library create a directory named KeyBindings. Create a file named DefaultKeyBinding.dict inside the directory. You can add key bindings in this format:

{
    "x" = (insertText:, "\U23CF");
    "y" = (insertText:, "hi"); /* warning: this will change 'y' to 'hi'! */
}

The LHS is the key combination you'll hit to enter the character. You can use the following characters to indicate command keys:

@ - Command

~ - Option

^ - Control

You'll need to look up the unicode for your character (in this case, ? is \U2234). So to type this character whenever you typed Control-M, you'd use

"^m" = (insertText:, "\U2234");

You can find more information here: http://www.hcs.harvard.edu/~jrus/site/cocoa-text.html

When you use a decorator, you're replacing one function with another. In other words, if you have a decorator

def logged(func):
    def with_logging(*args, **kwargs):
        print(func.__name__ + " was called")
        return func(*args, **kwargs)
    return with_logging

then when you say

@logged
def f(x):
   """does some math"""
   return x + x * x

it's exactly the same as saying

def f(x):
    """does some math"""
    return x + x * x
f = logged(f)

and your function f is replaced with the function with_logging. Unfortunately, this means that if you then say

print(f.__name__)

it will print with_logging because that's the name of your new function. In fact, if you look at the docstring for f, it will be blank because with_logging has no docstring, and so the docstring you wrote won't be there anymore. Also, if you look at the pydoc result for that function, it won't be listed as taking one argument x; instead it'll be listed as taking *args and **kwargs because that's what with_logging takes.

If using a decorator always meant losing this information about a function, it would be a serious problem. That's why we have functools.wraps. This takes a function used in a decorator and adds the functionality of copying over the function name, docstring, arguments list, etc. And since wraps is itself a decorator, the following code does the correct thing:

from functools import wraps
def logged(func):
    @wraps(func)
    def with_logging(*args, **kwargs):
        print(func.__name__ + " was called")
        return func(*args, **kwargs)
    return with_logging

@logged
def f(x):
   """does some math"""
   return x + x * x

print(f.__name__)  # prints 'f'
print(f.__doc__)   # prints 'does some math'

There is also HTML5 <input type="file[]" multiple /> (specification).

Browser support is quite good on desktop (just not supported by IE 9 and prior), less good on mobile, I guess because it's harder to implement correctly depending on the platform and version.

Add this to your project-level build.gradle file:

repositories {
    maven {
        url "https://maven.google.com"
    }
}

It worked for me

After :

sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0) 
    error("ERROR opening socket");

You can add (with standard C99 compound literal support) :

if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &(int){1}, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Or :

int enable = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &enable, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Sticky notes in Windows 10 are stored here: C:\Users\"Username"\Appdata\Roaming\Microsoft\Sticky Notes

If you want to restore your sticky notes from earlier versions of windwos, just copy the .snt file and place it in the above location.

N.B: Replace only if you don't have any new notes in Windows 10!

Use SharedPreferences, http://developer.android.com/reference/android/content/SharedPreferences.html

Here's a sample: http://developer.android.com/guide/topics/data/data-storage.html#pref

If the data structure is more complex or the data is large, use an Sqlite database; but for small amount of data and with a very simple data structure, I'd say, SharedPrefs will do and a DB might be overhead.

You need to change the loop from for ($i=1; $i<count($files); $i++) to for ($i=0; $i<count($files); $i++):

So the correct code is

<?php
$files = glob("images/*.*");

for ($i=0; $i<count($files); $i++) {
    $image = $files[$i];
    print $image ."<br />";
    echo '<img src="'.$image .'" alt="Random image" />'."<br /><br />";
}

?>

BufferedImage is a subclass of Image. You don't need to do any conversion.

How about .toDateString()?

Alternatively, use .getDate(), .getMonth(), and .getYear()?

In my mind, if you want to group things by date, you simply want to access the date, not set it. Through having some set way of accessing the date field, you can compare them and group them together, no?

Check out all the fun Date methods here: MDN Docs

Edit: If you want to keep it as a date object, just do this:

var newDate = new Date(oldDate.toDateString());

Date's constructor is pretty smart about parsing Strings (though not without a ton of caveats, but this should work pretty consistently), so taking the old Date and printing it to just the date without any time will result in the same effect you had in the original post.

Karl answered your search-path question, but as far as the "source of the files" goes, one thing to be aware of is that if you install the libfoo package and want to do some development with it (i.e., use its headers), you will also need to install libfoo-dev. The standard library header files are already in /usr/include, as you saw.

Note that some libraries with a lot of headers will install them to a subdirectory, e.g., /usr/include/openssl. To include one of those, just provide the path without the /usr/include part, for example:

#include <openssl/aes.h>

I have experimented many of the backslash escape characters. \n which is a new line feed can be put anywhere to bring the effect. One important thing to remember while using this character is that the operating system of the machine we are using might affect the output. As an example, I have printed a bunch of escape character and displayed the result as follow to proof that the OS will affect the output.

Code:

#include <stdio.h>
int main(void){
    printf("Hello World!");
    printf("Goodbye \a");
    printf("Hi \b");
    printf("Yo\f");
    printf("What? \t");
    printf("pewpew");
    return 0;
}

Short answer was provided here already: use <div [innerHTML]="yourHtml"> binding.

However the rest of the advices mentioned here might be misleading. Angular has a built-in sanitizing mechanism when you bind to properties like that. Since Angular is not a dedicated sanitizing library, it is overzealous towards suspicious content to not take any risks. For example, it sanitizes all SVG content into empty string.

You might hear advices to "sanitize" your content by using DomSanitizer to mark content as safe with bypassSecurityTrustXXX methods. There are also suggestions to use pipe to do that and that pipe is often called safeHtml.

All of this is misleading because it actually bypasses sanitizing, not sanitizing your content. This could be a security concern because if you ever do this on user provided content or on anything that you are not sure about — you open yourself up for a malicious code attacks.

If Angular removes something that you need by its built-in sanitization — what you can do instead of disabling it is delegate actual sanitization to a dedicated library that is good at that task. For example — DOMPurify.

I've made a wrapper library for it so it could be easily used with Angular: https://github.com/TinkoffCreditSystems/ng-dompurify

It also has a pipe to declaratively sanitize HTML:

<div [innerHtml]="value | dompurify"></div>

The difference to pipes suggested here is that it actually does do the sanitization through DOMPurify and therefore work for SVG.

One thing to keep in mind is DOMPurify is great for sanitizing HTML/SVG, but not CSS. So you can provider Angular's CSS sanitizer to handle CSS:

import {NgModule, ?_sanitizeStyle} from '@angular/core';
import {SANITIZE_STYLE} from '@tinkoff/ng-dompurify';

@NgModule({
    // ...
    providers: [
        {
            provide: SANITIZE_STYLE,
            useValue: ?_sanitizeStyle,
        },
    ],
    // ...
})
export class AppModule {}

It's internal — hense ? prefix, but this is how Angular team use it across their own packages as well anyway. That library also works for Angular Universal and server side renedring environment.

git config credential.helper store

Note: While this is convenient, Git will store your credentials in clear text in a local file (.git-credentials) under your project directory (see below for the "home" directory). If you don't like this, delete this file and switch to using the cache option.

If you want Git to resume to asking you for credentials every time it needs to connect to the remote repository, you can run this command:

git config --unset credential.helper

To store the passwords in .git-credentials in your %HOME% directory as opposed to the project directory: use the --global flag

git config --global credential.helper store

Several years on and I had a similar issue. In my case there were heavily nested interfaces and a preference for generating the concrete classes at runtime so that It would work with a generic class.

I decided to create a proxy class at run time that wraps the object returned by Newtonsoft.

The advantage of this approach is that it does not require a concrete implementation of the class and can handle any depth of nested interfaces automatically. You can see more about it on my blog.

using Castle.DynamicProxy;
using Newtonsoft.Json.Linq;
using System;
using System.Reflection;

    public static class JObjectExtension
    {
        private static ProxyGenerator _generator = new ProxyGenerator();

        public static dynamic toProxy(this JObject targetObject, Type interfaceType) 
        {
            return _generator.CreateInterfaceProxyWithoutTarget(interfaceType, new JObjectInterceptor(targetObject));
        }

        public static InterfaceType toProxy<InterfaceType>(this JObject targetObject)
        {

            return toProxy(targetObject, typeof(InterfaceType));
        }
    }

    public class JObjectInterceptor : IInterceptor
    {
        private JObject _target;

        public JObjectInterceptor(JObject target)
        {
            _target = target;
        }
        public void Intercept(IInvocation invocation)
        {

            var methodName = invocation.Method.Name;
            if(invocation.Method.IsSpecialName && methodName.StartsWith("get_"))
            {
                var returnType = invocation.Method.ReturnType;
                methodName = methodName.Substring(4);

                if (_target == null || _target[methodName] == null)
                {
                    if (returnType.GetTypeInfo().IsPrimitive || returnType.Equals(typeof(string)))
                    {

                        invocation.ReturnValue = null;
                        return;
                    }

                }

                if (returnType.GetTypeInfo().IsPrimitive || returnType.Equals(typeof(string)))
                {
                    invocation.ReturnValue = _target[methodName].ToObject(returnType);
                }
                else
                {
                    invocation.ReturnValue = ((JObject)_target[methodName]).toProxy(returnType);
                }
            }
            else
            {
                throw new NotImplementedException("Only get accessors are implemented in proxy");
            }

        }
    }



}

Usage:

var jObj = JObject.Parse(input);
InterfaceType proxyObject = jObj.toProxy<InterfaceType>();

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

Instead of manipulating the CMAKE_CXX_FLAGS strings directly (which could be done more nicely using string(APPEND CMAKE_CXX_FLAGS_DEBUG " -g3") btw), you can use add_compiler_options:

add_compile_options(
  "-Wall" "-Wpedantic" "-Wextra" "-fexceptions"
  "$<$<CONFIG:DEBUG>:-O0;-g3;-ggdb>"
)

This would add the specified warnings to all build types, but only the given debugging flags to the DEBUG build. Note that compile options are stored as a CMake list, which is just a string separating its elements by semicolons ;.

This will return true if a variable is unset or set to the empty string ("").

if [ -z "$MyVar" ]
then
   echo "The variable MyVar has nothing in it."
elif ! [ -z "$MyVar" ]
then
   echo "The variable MyVar has something in it."
fi

You can also use the RestSharp library for example

var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");            
client.Authenticator = new HttpBasicAuthenticator(userName, password);            
var request = new RestRequest(Method.POST); 
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");            
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

wc -l <file.txt>

Or

command | wc -l

# Creation of a dummy dataframe:
df1 = sqlContext.createDataFrame([("11/25/1991","11/24/1991","11/30/1991"),

df.show()

df.printSchema()

Here is the output:

+----------+----------+----------+----------+

root
 |-- first: string (nullable = true)
 |-- second: string (nullable = true)
 |-- third: string (nullable = true)
 |-- test: date (nullable = true)

I resolved a similar issue by wrapping the query in another query...

Initial query was working find giving individual columns of output, with some of the columns coming from sub queries with Max or Sum function, and other with "distinct" or case substitutions and such.

I encountered the collation error after attempting to create a single field of output with...

select
rtrim(field1)+','+rtrim(field2)+','+...

The query would execute as I wrote it, but the error would occur after saving the sql and reloading it.

Wound up fixing it with something like...

select z.field1+','+z.field2+','+... as OUTPUT_REC
from (select rtrim(field1), rtrim(field2), ... ) z

Some fields are "max" of a subquery, with a case substitution if null and others are date fields, and some are left joins (might be NULL)...in other words, mixed field types. I believe this is the cause of the issue being caused by OS collation and Database collation being slightly different, but by converting all to trimmed strings before the final select, it sorts it out, all in the SQL.

int rows, cols , i, j;
printf("Enter number of rows and cols for the matrix: \n");
scanf("%d %d",&rows, &cols);

int mat[rows][cols];

printf("enter the matrix:");

for(i = 0; i < rows ; i++)
    for(j = 0; j < cols; j++)
        scanf("%d", &mat[i][j]);

printf("\nThe Matrix is:\n");
for(i = 0; i < rows ; i++)
{
    for(j = 0; j < cols; j++)
    {
        printf("%d",mat[i][j]);
        printf("\t");
    }
    printf("\n");
}

}

Yes you can; it works on Android too:

tel: phone_number
Calls the entered phone number. Valid telephone numbers as defined in the IETF RFC 3966 are accepted. Valid examples include the following:

* tel:2125551212
* tel: (212) 555 1212

The Android browser uses the Phone app to handle the “tel” scheme, as defined by RFC 3966.
Clicking a link like:

<a href="tel:2125551212">2125551212</a>

on Android will bring up the Phone app and pre-enter the digits for 2125551212 without autodialing.

Have a look to RFC3966

(a[n:]+[default])[0]

This is probably better as a gets larger

(a[n:n+1]+[default])[0]

This works because if a[n:] is an empty list if n => len(a)

Here is an example of how this works with range(5)

>>> range(5)[3:4]
[3]
>>> range(5)[4:5]
[4]
>>> range(5)[5:6]
[]
>>> range(5)[6:7]
[]

And the full expression

>>> (range(5)[3:4]+[999])[0]
3
>>> (range(5)[4:5]+[999])[0]
4
>>> (range(5)[5:6]+[999])[0]
999
>>> (range(5)[6:7]+[999])[0]
999

My contribution:

I'm assuming you want the total string length to include the 'dot'. If not it's still simple to rewrite to add an extra zero if the number is a float.

padZeros = function (num, zeros) {
        return (((num < 0) ? "-" : "") + Array(++zeros - String(Math.abs(num)).length).join("0") + Math.abs(num));
    }

Yes. Internally it is implemented as open hashing based on a primitive polynomial over Z/2 (source).

With the aws dynamodb cli you can get it via scan as follows:

aws dynamodb scan --table-name <TABLE_NAME> --select "COUNT"

The response will look similar to this:

{
    "Count": 123,
    "ScannedCount": 123,
    "ConsumedCapacity": null
}

notice that this information is in real time in contrast to the describe-table api

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

Doing a 302 will typically cause clients to convert a POST to a GET request.

SELECT DISTINCT C.valueC 
FROM C 
  LEFT JOIN B ON C.id = B.lookupC
  LEFT JOIN A ON B.id = A.lookupB
WHERE C.id IS NOT NULL

I don't see a good reason why you want to limit the result sets of A and B because what you want to have is a list of all C's that are referenced by A. I did a distinct on C.valueC because i guessed you wanted a unique list of C's.

EDIT: I agree with your argument. Even if your solution looks a bit nested it seems to be the best and fastest way to use your knowledge of the data and reduce the result sets.

There is no distinct join construct you could use so just stay with what you already have :)

The difference can be understood by this simple C++ code below:

int i, j, k, l;
i = 1; //initialize int i with 1
j = i+1; //add 1 with i and set that as the value of j. i is still 1
k = i++; //k gets the current value of i, after that i is incremented. So here i is 2, but k is 1
l = ++i; // i is incremented first and then returned. So the value of i is 3 and so does l.
cout << i << ' ' << j << ' ' << k << ' '<< l << endl;
return 0;

just type "git push" if this doesn't give you a positive replay, then check if you are connected with your repository correctly.

I hope it also useful

window.addEventListener("load", function() 
{
    if(!window.pageYOffset)
    { 
        hideAddressBar(); 
    }
    window.addEventListener("orientationchange", hideAddressBar);
});

Once I needed to resize photos from camera for developing:

• Original filesize: 2800 kB
• Resolution: 3264x2448

Command:

mogrify -quality "97%" -resize 2048x2048 -filter Lanczos -interlace Plane -gaussian-blur 0.05 

• Result filesize 753 kB
• Resolution 2048x2048

and I can't see any changes in full screen with my 1920x1080 resolution monitor. 2048 resolution is the best for developing 10 cm photos at maximum quality of 360 dpi. I don't want to strip it.

edit: I noticed that I even get much better results without blurring. Without blurring filesize is 50% of original, but quality is better (when zooming).

If you have array of arrays and want to concat the elements into a single array, try the following code (Requires ES2015):

let arrOfArr = [[1,2,3,4],[5,6,7,8]];
let newArr = [];
for (let arr of arrOfArr) {
    newArr.push(...arr);
}

console.log(newArr);
//Output: [1,2,3,4,5,6,7,8];

Or if you're into functional programming

let arrOfArr = [[1,2,3,4],[5,6,7,8]];
let newArr = arrOfArr.reduce((result,current)=>{
    result.push(...current);
    return result;
});

console.log(newArr);
//Output: [1,2,3,4,5,6,7,8];

Or even better with ES5 syntax, without the spread operator

var arrOfArr = [[1,2,3,4],[5,6,7,8]];
var newArr = arrOfArr.reduce((result,current)=>{
    return result.concat(current);
});
console.log(newArr);
//Output: [1,2,3,4,5,6,7,8];

This way is handy if you do not know the no. of arrays at the code time.

You can do this:

<img src="your image" style="transform:rotate(90deg);">

it is much easier.

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++. Be aware, however, that it is intended purely as a reference for experienced users willing to devote considerable time and effort to its understanding. The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US). For most people, the final draft before standardization is more than adequate (and free). Many will prefer an even newer draft, documenting new features that are likely to be included in C++20.

• Overview of the New C++ (C++11/14) (PDF only) (Scott Meyers) (updated for C++14) These are the presentation materials (slides and some lecture notes) of a three-day training course offered by Scott Meyers, who's a highly respected author on C++. Even though the list of items is short, the quality is high.

• The C++ Core Guidelines (C++11/14/17/…) (edited by Bjarne Stroustrup and Herb Sutter) is an evolving online document consisting of a set of guidelines for using modern C++ well. The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management and concurrency affecting application architecture and library design. The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• The C++ Super-FAQ (Marshall Cline, Bjarne Stroustrup and others) is an effort by the Standard C++ Foundation to unify the C++ FAQs previously maintained individually by Marshall Cline and Bjarne Stroustrup and also incorporating new contributions. The items mostly address issues at an intermediate level and are often written with a humorous tone. Not all items might be fully up to date with the latest edition of the C++ standard yet.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library. The documentation is very precise but is easier to read than the official standard document and provides better navigation due to its wiki nature. The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

Why you need to implement shuffle when it already exists? Stay on the shoulders of giants.

import random

d1 = {0:'zero', 1:'one', 2:'two', 3:'three', 4:'four',
     5:'five', 6:'six', 7:'seven', 8:'eight', 9:'nine'}

keys = list(d1)
random.shuffle(keys)

d2 = {}
for key in keys: d2[key] = d1[key]

print(d1)
print(d2)

You can select every column from that sub-query by aliasing it and adding the alias before the *:

SELECT t.*, a+b AS total_sum
FROM
(
   SELECT SUM(column1) AS a, SUM(column2) AS b
   FROM table
) t

Apply float:left; to both of your divs should make them stand side by side.

You just need to add three file and two css links. You can either cdn's as well. Links for the js files and css files are as such :-

1. jQuery.dataTables.min.js
2. dataTables.bootstrap.min.js
3. dataTables.bootstrap.min.css
4. bootstrap-datepicker.css
5. bootstrap-datepicker.js

They are valid if you are using bootstrap in your project.

I hope this will help you. Regards, Vivek Singla

Here is an example using RSA.

Important: There is a limit to the size of data you can encrypt with the RSA encryption, KeySize - MinimumPadding. e.g. 256 bytes (assuming 2048 bit key) - 42 bytes (min OEAP padding) = 214 bytes (max plaintext size)

Replace your_rsa_key with your RSA key.

var provider = new System.Security.Cryptography.RSACryptoServiceProvider();
provider.ImportParameters(your_rsa_key);

var encryptedBytes = provider.Encrypt(
    System.Text.Encoding.UTF8.GetBytes("Hello World!"), true);

string decryptedTest = System.Text.Encoding.UTF8.GetString(
    provider.Decrypt(encryptedBytes, true));

I had a similar problem with 2D arrays and ended here. I was copying the main array and changing the inner arrays' values and was surprised when the values changed in both copies. Basically both copies were independent but contained references to the same inner arrays and I had to make an array of copies of the inner arrays to get what I wanted.

This is sometimes called a deep copy. The same term "deep copy" can also have a completely different and arguably more complex meaning, which can be confusing, especially to someone not figuring out why their copied arrays don't behave as they should. It probably isn't the OP's problem, but I hope it can still be helpful.

A ClusterIP exposes the following:

• spec.clusterIp:spec.ports[*].port

You can only access this service while inside the cluster. It is accessible from its spec.clusterIp port. If a spec.ports[*].targetPort is set it will route from the port to the targetPort. The CLUSTER-IP you get when calling kubectl get services is the IP assigned to this service within the cluster internally.

A NodePort exposes the following:

• <NodeIP>:spec.ports[*].nodePort
• spec.clusterIp:spec.ports[*].port

If you access this service on a nodePort from the node's external IP, it will route the request to spec.clusterIp:spec.ports[*].port, which will in turn route it to your spec.ports[*].targetPort, if set. This service can also be accessed in the same way as ClusterIP.

Your NodeIPs are the external IP addresses of the nodes. You cannot access your service from spec.clusterIp:spec.ports[*].nodePort.

A LoadBalancer exposes the following:

• spec.loadBalancerIp:spec.ports[*].port
• <NodeIP>:spec.ports[*].nodePort
• spec.clusterIp:spec.ports[*].port

You can access this service from your load balancer's IP address, which routes your request to a nodePort, which in turn routes the request to the clusterIP port. You can access this service as you would a NodePort or a ClusterIP service as well.

The last parameter to the rgba() function is the "alpha" or "opacity" parameter. If you set it to 0 it will mean "completely transparent", and the first three parameters (the red, green, and blue channels) won't matter because you won't be able to see the color anyway.

With that in mind, I would choose rgba(0, 0, 0, 0) because:

1. it's less typing,
2. it keeps a few extra bytes out of your CSS file, and
3. you will see an obvious problem if the alpha value changes to something undesirable.

You could avoid the rgba model altogether and use the transparent keyword instead, which according to w3.org, is equivalent to "transparent black" and should compute to rgba(0, 0, 0, 0). For example:

h1 {
    background-color: transparent;
}

This saves you yet another couple bytes while your intentions of using transparency are obvious (in case one is unfamiliar with RGBA).

As of CSS3, you can use the transparent keyword for any CSS property that accepts a color.

The promise will always log pending as long as its results are not resolved yet. You must call .then on the promise to capture the results regardless of the promise state (resolved or still pending):

let AuthUser = function(data) {
  return google.login(data.username, data.password).then(token => { return token } )
}

let userToken = AuthUser(data)
console.log(userToken) // Promise { <pending> }

userToken.then(function(result) {
   console.log(result) // "Some User token"
})

Why is that?

Promises are forward direction only; You can only resolve them once. The resolved value of a Promise is passed to its .then or .catch methods.

Details

According to the Promises/A+ spec:

The promise resolution procedure is an abstract operation taking as input a promise and a value, which we denote as [[Resolve]](promise, x). If x is a thenable, it attempts to make promise adopt the state of x, under the assumption that x behaves at least somewhat like a promise. Otherwise, it fulfills promise with the value x.

This treatment of thenables allows promise implementations to interoperate, as long as they expose a Promises/A+-compliant then method. It also allows Promises/A+ implementations to “assimilate” nonconformant implementations with reasonable then methods.

This spec is a little hard to parse, so let's break it down. The rule is:

If the function in the .then handler returns a value, then the Promise resolves with that value. If the handler returns another Promise, then the original Promise resolves with the resolved value of the chained Promise. The next .then handler will always contain the resolved value of the chained promise returned in the preceding .then.

The way it actually works is described below in more detail:

1. The return of the .then function will be the resolved value of the promise.

function initPromise() {
  return new Promise(function(res, rej) {
    res("initResolve");
  })
}

initPromise()
  .then(function(result) {
    console.log(result); // "initResolve"
    return "normalReturn";
  })
  .then(function(result) {
    console.log(result); // "normalReturn"
  });

2. If the .then function returns a Promise, then the resolved value of that chained promise is passed to the following .then.

function initPromise() {
  return new Promise(function(res, rej) {
    res("initResolve");
  })
}

initPromise()
  .then(function(result) {
    console.log(result); // "initResolve"
    return new Promise(function(resolve, reject) {
       setTimeout(function() {
          resolve("secondPromise");
       }, 1000)
    })
  })
  .then(function(result) {
    console.log(result); // "secondPromise"
  });

You can do this faster using a nearly optimal trial division sieve in one (long) line like this:

Enumerable.Range(0, Math.Floor(2.52*Math.Sqrt(num)/Math.Log(num))).Aggregate(
    Enumerable.Range(2, num-1).ToList(), 
    (result, index) => { 
        var bp = result[index]; var sqr = bp * bp;
        result.RemoveAll(i => i >= sqr && i % bp == 0); 
        return result; 
    }
);

The approximation formula for number of primes used here is p(x) < 1.26 x / ln(x). We only need to test by primes not greater than x = sqrt(num).

Note that the sieve of Eratosthenes has much better run time complexity than trial division (should run much faster for bigger num values, when properly implemented).

An array doesn't have an add method. You assign a value to an element of the array with num[i]=value;.

public static void main(String[] args) {
    int[] num = new int[args.length];
    for (int i=0; i < num.length; i++){
      int neki = Integer.parseInt(args[i]);
      num[i]=neki;
    }
}

(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).

My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert() changed names to create() so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!

The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.

Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload class. This snippet assumes your auth code works where your service endpoint is DRIVE with a minimum auth scope of https://www.googleapis.com/auth/drive.file.

# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'

# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()
if rsp:
    print('Imported %r to %r (as %s)' % (SRC_FILENAME, DST_FILENAME, rsp['mimeType']))

Better yet, rather than uploading to My Drive, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.

If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.

Firstly you make sure you have add permission in manifest file.

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

Check if the application has draw over other apps permission or not? This permission is by default available for API<23. But for API > 23 you have to ask for the permission in runtime.

You need to concatenate your string.

document.getElementById(tabName).style.backgroundImage = 'url(buttons/' + imagePrefix + '.png)';

The way you had it, it's just making 1 long string and not actually interpreting imagePrefix.

I would even suggest creating the string separate:

function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
    var urlString = 'url(buttons/' + imagePrefix + '.png)';
    document.getElementById(tabName).style.backgroundImage =  urlString;
}

As mentioned by David Thomas below, you can ditch the double quotes in your string. Here is a little article to get a better idea of how strings and quotes/double quotes are related: http://www.quirksmode.org/js/strings.html

You separate multiple program arguments with spaces. (this was not obvious to me)

Program arguments:Julia 52 Actress

This likely doesn't work with start, as that starts a new window, but to answer your question:

If the command returns a error level you can check the following ways

By Specific Error Level

commandhere
if %errorlevel%==131 echo do something

By If Any Error

commandhere || echo what to do if error level ISN'T 0

By If No Error

commandhere && echo what to do if error level IS 0

If it does not return a error level but does give output, you can catch it in a variable and determine by the output, example (note the tokens and delims are just examples and would likely fail with any special characters)

By Parsing Full Output

for /f "tokens=* delims=" %%a in ('somecommand') do set output=%%a
if %output%==whateveritwouldsayinerror echo error

Or you could just look for a single phrase in the output like the word Error

By Checking For String

commandhere | find "Error" || echo There was no error!
commandhere | find "Error" && echo There was an error!

And you could even mix together (just remember to escape | with ^| if in a for statement)

Hope this helps.

As others have mentioned, you can use nested functions by using the gnu language extensions in gcc. If you (or your project) sticks to the gcc toolchain, your code will be mostly portable across the different architectures targeted by the gcc compiler.

However, if there is a possible requirement that you might need to compile code with a different toolchain, then I'd stay away from such extensions.

I'd also tread with care when using nested functions. They are a beautiful solution for managing the structure of complex, yet cohesive blocks of code (the pieces of which are not meant for external/general use.) They are also very helpful in controlling namespace pollution (a very real concern with naturally complex/long classes in verbose languages.)

But like anything, they can be open to abuse.

It is sad that C/C++ does not support such features as an standard. Most pascal variants and Ada do (almost all Algol-based languages do). Same with JavaScript. Same with modern languages like Scala. Same with venerable languages like Erlang, Lisp or Python.

And just as with C/C++, unfortunately, Java (with which I earn most of my living) does not.

I mention Java here because I see several posters suggesting usage of classes and class' methods as alternatives to nested functions. And that's also the typical workaround in Java.

Short answer: No.

Doing so tend to introduce artificial, needless complexity on a class hierarchy. With all things being equal, the ideal is to have a class hierarchy (and its encompassing namespaces and scopes) representing an actual domain as simple as possible.

Nested functions help deal with "private", within-function complexity. Lacking those facilities, one should try to avoid propagating that "private" complexity out and into one's class model.

In software (and in any engineering discipline), modeling is a matter of trade-offs. Thus, in real life, there will be justified exceptions to those rules (or rather guidelines). Proceed with care, though.

Use this:

mysqli_query($this->db_link, $query) or die(mysqli_error($this->db_link)); 
# mysqli_query($link,$query) returns 0 if there's an error.
# mysqli_error($link) returns a string with the last error message

You can also use this to print the error code.

echo mysqli_errno($this->db_link);

Take a look here and here

Preface

This post is meant to be an easy-to-read alternative to litb's post.

The underlying purpose is the same; an explanation to "When?" and "Why?" typename and template must be applied.

What's the purpose of typename and template?

typename and template are usable in circumstances other than when declaring a template.

There are certain contexts in C++ where the compiler must explicitly be told how to treat a name, and all these contexts have one thing in common; they depend on at least one template-parameter.

We refer to such names, where there can be an ambiguity in interpretation, as; "dependent names".

This post will offer an explanation to the relationship between dependent-names, and the two keywords.

A snippet says more than 1000 words

Try to explain what is going on in the following function-template, either to yourself, a friend, or perhaps your cat; what is happening in the statement marked (A)?

template<class T> void f_tmpl () { T::foo * x; /* <-- (A) */ }

It might not be as easy as one thinks, more specifically the result of evaluating (A) heavily depends on the definition of the type passed as template-parameter T.

Different Ts can drastically change the semantics involved.

struct X { typedef int       foo;       }; /* (C) --> */ f_tmpl<X> ();
struct Y { static  int const foo = 123; }; /* (D) --> */ f_tmpl<Y> ();

The two different scenarios:

• If we instantiate the function-template with type X, as in (C), we will have a declaration of a pointer-to int named x, but;

• if we instantiate the template with type Y, as in (D), (A) would instead consist of an expression that calculates the product of 123 multiplied with some already declared variable x.

The Rationale

The C++ Standard cares about our safety and well-being, at least in this case.

To prevent an implementation from potentially suffering from nasty surprises, the Standard mandates that we sort out the ambiguity of a dependent-name by explicitly stating the intent anywhere we'd like to treat the name as either a type-name, or a template-id.

If nothing is stated, the dependent-name will be considered to be either a variable, or a function.

How to handle dependent names?

If this was a Hollywood film, dependent-names would be the disease that spreads through body contact, instantly affects its host to make it confused. Confusion that could, possibly, lead to an ill-formed perso-, erhm.. program.

A dependent-name is any name that directly, or indirectly, depends on a template-parameter.

template<class T> void g_tmpl () {
   SomeTrait<T>::type                   foo; // (E), ill-formed
   SomeTrait<T>::NestedTrait<int>::type bar; // (F), ill-formed
   foo.data<int> ();                         // (G), ill-formed    
}

We have four dependent names in the above snippet:

• E)
  • "type" depends on the instantiation of SomeTrait<T>, which include T, and;
• F)
  • "NestedTrait", which is a template-id, depends on SomeTrait<T>, and;
  • "type" at the end of (F) depends on NestedTrait, which depends on SomeTrait<T>, and;
• G)
  • "data", which looks like a member-function template, is indirectly a dependent-name since the type of foo depends on the instantiation of SomeTrait<T>.

Neither of statement (E), (F) or (G) is valid if the compiler would interpret the dependent-names as variables/functions (which as stated earlier is what happens if we don't explicitly say otherwise).

The solution

To make g_tmpl have a valid definition we must explicitly tell the compiler that we expect a type in (E), a template-id and a type in (F), and a template-id in (G).

template<class T> void g_tmpl () {
   typename SomeTrait<T>::type foo;                            // (G), legal
   typename SomeTrait<T>::template NestedTrait<int>::type bar; // (H), legal
   foo.template data<int> ();                                  // (I), legal
}

Every time a name denotes a type, all names involved must be either type-names or namespaces, with this in mind it's quite easy to see that we apply typename at the beginning of our fully qualified name.

template however, is different in this regard, since there's no way of coming to a conclusion such as; "oh, this is a template, then this other thing must also be a template". This means that we apply template directly in front of any name that we'd like to treat as such.

Can I just stick the keywords in front of any name?

"Can I just stick typename and template in front of any name? I don't want to worry about the context in which they appear..." - Some C++ Developer

The rules in the Standard states that you may apply the keywords as long as you are dealing with a qualified-name (K), but if the name isn't qualified the application is ill-formed (L).

namespace N {
  template<class T>
  struct X { };
}

         N::         X<int> a; // ...  legal
typename N::template X<int> b; // (K), legal
typename template    X<int> c; // (L), ill-formed

^{Note: Applying typename or template in a context where it is not required is not considered good practice; just because you can do something, doesn't mean that you should.}

Additionally there are contexts where typename and template are explicitly disallowed:

• When specifying the bases of which a class inherits

  Every name written in a derived class's base-specifier-list is already treated as a type-name, explicitly specifying typename is both ill-formed, and redundant.

                      // .------- the base-specifier-list
    template<class T> // v
    struct Derived      : typename SomeTrait<T>::type /* <- ill-formed */ {
      ...
    };
  

  
  

• When the template-id is the one being referred to in a derived class's using-directive

    struct Base {
      template<class T>
      struct type { };
    };
  
    struct Derived : Base {
      using Base::template type; // ill-formed
      using Base::type;          // legal
    };
  

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

sudo apt-get install openjfx

This happened to me when I updated web.config without updating all referenced dlls.

Using proper diff filter (beware of Meld's default directory compare filter ignoring binaries) the difference was identified, files were copied and everything worked fine.

If there is no existing method then I guess you can iterate from 0 to input.size()/2, taking each consecutive element and appending it to a new ArrayList.

EDIT: Actually, I think you can take that List and use it to instantiate a new ArrayList using one of the ArrayList constructors.

I would say the server is running out of physical/swap memory, so PHP can't allocate enough memory.

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

Quickest 2D context image rotation method

A general purpose image rotation, position, and scale.

// no need to use save and restore between calls as it sets the transform rather 
// than multiply it like ctx.rotate ctx.translate ctx.scale and ctx.transform
// Also combining the scale and origin into the one call makes it quicker
// x,y position of image center
// scale scale of image
// rotation in radians.
function drawImage(image, x, y, scale, rotation){
    ctx.setTransform(scale, 0, 0, scale, x, y); // sets scale and origin
    ctx.rotate(rotation);
    ctx.drawImage(image, -image.width / 2, -image.height / 2);
} 

If you wish to control the rotation point use the next function

// same as above but cx and cy are the location of the point of rotation
// in image pixel coordinates
function drawImageCenter(image, x, y, cx, cy, scale, rotation){
    ctx.setTransform(scale, 0, 0, scale, x, y); // sets scale and origin
    ctx.rotate(rotation);
    ctx.drawImage(image, -cx, -cy);
} 

To reset the 2D context transform

ctx.setTransform(1,0,0,1,0,0); // which is much quicker than save and restore

Thus to rotate image to the left (anti clockwise) 90 deg

drawImage(image, canvas.width / 2, canvas.height / 2, 1, - Math.PI / 2);

Thus to rotate image to the right (clockwise) 90 deg

drawImage(image, canvas.width / 2, canvas.height / 2, 1, Math.PI / 2);

In my case I had to add android:name=".activity.SkeletonAppActivity" instead of android:name=".SkeletonAppActivity" in the manifest file for the main activity. SkeletonAppActivity was in a different package from the application class. Good luck!

I had the same issue. I tried making changes to "Internal Testers." No effect. I uploaded a new build using the Application Loader. Once the upload completed, the previous build changed from "Processing" to being available.

If it contains less than 3 slashes thus you've it got and if not then we can find the occurrence between it:

import re

link = http://forum.unisoftdev.com/something

slash_count = len(re.findall("/", link))
print slash_count # output: 3

if slash_count > 2:
   regex = r'\:\/\/(.*?)\/'
   pattern  = re.compile(regex)
   path = re.findall(pattern, url)

   print path

In my experience, the most friendly way of dealing with this is to have a function that converts a string into a table of values.

There are many splitter functions available on the web, you'll easily find one for whatever if your flavour of SQL.

You can then do...

SELECT * FROM table WHERE id IN (SELECT id FROM split(@list_of_ids))

Or

SELECT * FROM table INNER JOIN (SELECT id FROM split(@list_of_ids)) AS list ON list.id = table.id

(Or similar)

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

Spring Injection

I know this is sort of late to the game, but here is one I use for Spring Injection in a class:

${:import(org.springframework.beans.factory.annotation.Autowired)}
private ${class_to_inject} ${var_name};

@Autowired
public void set${class_to_inject}(${class_to_inject} ${var_name}) {
  this.${var_name} = ${var_name};
}

public ${class_to_inject} get${class_to_inject}() {
  return this.${var_name};
}

You don't need to use the clipboard, you can export directly the whole resultset (not just what you see) to a file :

1. Execute your query
2. Right click any anywhere in the results
3. click "Export resultset..." to open the export wizard
4. Choose the format you want (CSV according to your question)
5. Review the settings in the next panes when clicking "Next".
6. Set the folder where the file will be created, and "Finish"

The export runs in the background, a popup will appear when it's done.

In newer versions of DBeaver you can just :

1. right click the SQL of the query you want to export
2. Execute > Export from query
3. Choose the format you want (CSV according to your question)
4. Review the settings in the next panes when clicking "Next".
5. Set the folder where the file will be created, and "Finish"

The export runs in the background, a popup will appear when it's done.

Compared to the previous way of doing exports, this saves you step 1 (executing the query) which can be handy with time/resource intensive queries.

Setting Activity’s title from a Fragment messes up responsibility levels. Fragment is contained within an Activity, so this is the Activity, which should set its own title according to the type of the Fragment for example.

Suppose you have an interface:

interface TopLevelFragment
{
    String getTitle();
}

The Fragments which can influence the Activity’s title then implement this interface. While in the hosting activity you write:

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    FragmentManager fm = getFragmentManager();
    fm.beginTransaction().add(0, new LoginFragment(), "login").commit();
}

@Override
public void onAttachFragment(Fragment fragment)
{
    super.onAttachFragment(fragment);

    if (fragment instanceof TopLevelFragment)
        setTitle(((TopLevelFragment) fragment).getTitle());
}

In this manner Activity is always in control what title to use, even if several TopLevelFragments are combined, which is quite possible on a tablet.

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

The font tag has been deprecated for some time now.

That being said, the reason why both of your tables display with the same font size is that the 'size' attribute only accepts values ranging from 1 - 7. The smallest size is 1. The largest size is 7. The default size is 3. Any values larger than 7 will just display the same as if you had used 7, because 7 is the maximum value allowed.

And as @Alex H said, you should be using CSS for this.

Most application can be solved in [insert your favorite language, paradigm, etc. here].

Although, this is true, different tools can be used to solve different problems. Functional just allows another high (higher?) level abstraction that allows to do our jobs more effectively when used correctly.

I believe your "P" as the dataWithBytes param

NSData *keydata = [NSData dataWithBytes:P length:len];

should be "buf"

NSData *keydata = [NSData dataWithBytes:buf length:len];

since i2d_PrivateKey puts the pointer to the output buffer p at the end of the buffer and waiting for further input, and buf is still pointing to the beginning of your buffer.

The following code works for me where pkey is a pointer to an EVP_PKEY:

unsigned char *buf, *pp;
int len = i2d_PrivateKey(pkey, NULL);
buf = OPENSSL_malloc(len); 
pp = buf;
i2d_PrivateKey(pkey, &pp);

NSData* pkeyData = [NSData dataWithBytes:(const void *)buf length:len];
DLog(@"Private key in hex (%d): %@", len, pkeyData);

You can use an online converter to convert your binary data into base 64 (http://tomeko.net/online_tools/hex_to_base64.php?lang=en) and compare it to the private key in your cert file after using the following command and checking the output of mypkey.pem:

openssl pkcs12 -in myCert.p12 -nocerts -nodes -out mypkey.pem

I referenced your question and this EVP function site for my answer.

It is easy. If you have saved your file as A.text first thing you should do is save it as A.java. Now it is a Java file.

Now you need to open cmd and set path to you A.java file before compile it. you can refer this for that.

Then you can compile your file using command

javac A.java

Then run it using

java A

So that is how you compile and run a java program in cmd. You can also go through these material that is Java in depth lessons. Lot of things you need to understand in Java is covered there for beginners.

replace:true is Deprecated

From the Docs:

replace ([DEPRECATED!], will be removed in next major release - i.e. v2.0)

specify what the template should replace. Defaults to false.

• true - the template will replace the directive's element.
• false - the template will replace the contents of the directive's element.

-- AngularJS Comprehensive Directive API

From GitHub:

Caitp-- It's deprecated because there are known, very silly problems with replace: true, a number of which can't really be fixed in a reasonable fashion. If you're careful and avoid these problems, then more power to you, but for the benefit of new users, it's easier to just tell them "this will give you a headache, don't do it".

-- AngularJS Issue #7636

Update

Note: replace: true is deprecated and not recommended to use, mainly due to the issues listed here. It has been completely removed in the new Angular.

Issues with replace: true

• Attribute values are not merged
• Directives are not deduplicated before compilation
• transclude: element in the replace template root can have unexpected effects

For more information, see

• AngularJS $compile Service API Reference - Issues with replace:true

>> is the Arithmetic Right Shift operator. All of the bits in the first operand are shifted the number of places indicated by the second operand. The leftmost bits in the result are set to the same value as the leftmost bit in the original number. (This is so that negative numbers remain negative.)

Here's your specific case:

00101011
  001010 <-- Shifted twice to the right (rightmost bits dropped)
00001010 <-- Leftmost bits filled with 0s (to match leftmost bit in original number)

Besides these given great answers, What I have learned is that:

NEVER compare objects with == unless you intend to be comparing them by their references.

Edit your 'my-default.ini' file (by default it comes with commented properties)as below ie.

basedir=D:/D_Drive/mysql-5.6.20-win32
datadir=D:/D_Drive/mysql-5.6.20-win32/data
port=8888

There is very good article present that dictates commands to create user, browse tables etc ie.

Assuming that Test is a class with a defined constructor, there's no difference. The latter form makes it a little clearer that Test's constructor is running, but that's about it.

Perhaps create a shared Fruit interface that provides isDecayed. fruits is now of type Fruit[] so the type can be explicit. Like this:

interface Fruit {
    isDecayed: boolean;
}

interface Apple extends Fruit {
    color: string;
}

interface Pear extends Fruit {
    weight: number;
}

interface FruitBasket {
    apples: Apple[];
    pears: Pear[];
}


const fruitBasket: FruitBasket = { apples: [], pears: [] };
const key: keyof FruitBasket = Math.random() > 0.5 ? 'apples': 'pears'; 
const fruits: Fruit[] = fruitBasket[key];

const freshFruits = fruits.filter((fruit) => !fruit.isDecayed);

this is easily achievable with RegExp!

const str = 'Hello RegEx!';
const index = 11;
const replaceWith = 'p';

//'Hello RegEx!'.replace(/^(.{11})(.)/, `$1p`);
str.replace(new RegExp(`^(.{${ index }})(.)`), `$1${ replaceWith }`);

//< "Hello RegExp"

Using set elements ... isn't always the best way. It would be useful if there were a distinct set string-elements ....

So, I use these functions in my .gdbinit:

define pstr
  ptype $arg0._M_dataplus._M_p
  printf "[%d] = %s\n", $arg0._M_string_length, $arg0._M_dataplus._M_p
end

define pcstr
  ptype $arg0
  printf "[%d] = %s\n", strlen($arg0), $arg0
end

Caveats:

• The first is c++ lib dependent as it accesses members of std::string, but is easily adjusted.
• The second can only be used on a running program as it calls strlen.

The encrypted string had two special characters, + and =.

'+' sign was giving the error, so below solution worked well:

//replace + sign

encryted_string = encryted_string.Replace("+", "%2b");

//`%2b` is HTTP encoded string for **+** sign

OR

//encode special charactes 

encryted_string = HttpUtility.UrlEncode(encryted_string);

//then pass it to the decryption process

How floats work

When floating elements exist on the page, non-floating elements wrap around the floating elements, similar to how text goes around a picture in a newspaper. From a document perspective (the original purpose of HTML), this is how floats work.

float vs display:inline

Before the invention of display:inline-block, websites use float to set elements beside each other. float is preferred over display:inline since with the latter, you can't set the element's dimensions (width and height) as well as vertical paddings (top and bottom) - which floated elements can do since they're treated as block elements.

Float problems

The main problem is that we're using float against its intended purpose.

Another is that while float allows side-by-side block-level elements, floats do not impart shape to its container. It's like position:absolute, where the element is "taken out of the layout". For instance, when an empty container contains a floating 100px x 100px <div>, the <div> will not impart 100px in height to the container.

Unlike position:absolute, it affects the content that surrounds it. Content after the floated element will "wrap" around the element. It starts by rendering beside it and then below it, like how newspaper text would flow around an image.

Clearfix to the rescue

What clearfix does is to force content after the floats or the container containing the floats to render below it. There are a lot of versions for clear-fix, but it got its name from the version that's commonly being used - the one that uses the CSS property clear.

Examples

Here are several ways to do clearfix , depending on the browser and use case. One only needs to know how to use the clear property in CSS and how floats render in each browser in order to achieve a perfect cross-browser clear-fix.

What you have

Your provided style is a form of clearfix with backwards compatibility. I found an article about this clearfix. It turns out, it's an OLD clearfix - still catering the old browsers. There is a newer, cleaner version of it in the article also. Here's the breakdown:

• The first clearfix you have appends an invisible pseudo-element, which is styled clear:both, between the target element and the next element. This forces the pseudo-element to render below the target, and the next element below the pseudo-element.

• The second one appends the style display:inline-block which is not supported by earlier browsers. inline-block is like inline but gives you some properties that block elements, like width, height as well as vertical padding. This was targeted for IE-MAC.

• This was the reapplication of display:block due to IE-MAC rule above. This rule was "hidden" from IE-MAC.

All in all, these 3 rules keep the .clearfix working cross-browser, with old browsers in mind.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

This is a classic example of composition vs inheritance.

In this specific case:

Is the team a list of players with added behavior

or

Is the team an object of its own that happens to contain a list of players.

By extending List you are limiting yourself in a number of ways:

1. You cannot restrict access (for example, stopping people changing the roster). You get all the List methods whether you need/want them all or not.

2. What happens if you want to have lists of other things as well. For example, teams have coaches, managers, fans, equipment, etc. Some of those might well be lists in their own right.

3. You limit your options for inheritance. For example you might want to create a generic Team object, and then have BaseballTeam, FootballTeam, etc. that inherit from that. To inherit from List you need to do the inheritance from Team, but that then means that all the various types of team are forced to have the same implementation of that roster.

Composition - including an object giving the behavior you want inside your object.

Inheritance - your object becomes an instance of the object that has the behavior you want.

Both have their uses, but this is a clear case where composition is preferable.

BEFORE you follow the tip from Joki's answer (below) and IF :

• you have MacOS 10.14.6

• at /Library/Developer/CommandLineTools/SDKs/ you have folders MacOSX.sdk(symbolic), MacOSX10.14.sdk, MacOSX10.15.sdk

• Move MacOSX10.15.sdk to anywhere (admin privileges needs)

• Delete symbolic link (admin privileges needs)

• At /Library/Developer/CommandLineTools/SDKs/ create another symbolic link now to MacOSX10.14.sdk folder using (admin privileges needs)

  sudo ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk MacOSX.sdk

• Now you can follow Joki's answer

WARNING! If you move MacOSX10.15.sdk folder to /Library/Developer/CommandLineTools/SDKs/ again, the command

ruby -rrbconfig -e 'puts RbConfig::CONFIG["rubyhdrdir"]'

will show MacOSX10.15.sdk folder like default again, nowadays I dunno how to fix it! My suggestion, compress the folder and put the original folder until fix will be available.

I like to use:

make --debug=j

https://linux.die.net/man/1/make

--debug[=FLAGS]

Print debugging information in addition to normal processing. If the FLAGS are omitted, then the behavior is the same as if -d was specified. FLAGS may be a for all debugging output (same as using -d), b for basic debugging, v for more verbose basic debugging, i for showing implicit rules, j for details on invocation of commands, and m for debugging while remaking makefiles.

Following syntax may help for adding a main page and related subpages for doxygen:

/*! \mainpage Drawing Shapes
 *
 * This project helps user to draw shapes.
 * Currently two types of shapes can be drawn:
 * - \subpage drawingRectanglePage "How to draw rectangle?"
 *
 * - \subpage drawingCirclePage "How to draw circle?"
 *
 */ 

/*! \page drawingRectanglePage How to draw rectangle?
 *
 * Lorem ipsum dolor sit amet
 *
 */

/*! \page drawingCirclePage How to draw circle?
 *
 * This page is about how to draw a circle.
 * Following sections describe circle:
 * - \ref groupCircleDefinition "Definition of Circle"
 * - \ref groupCircleClass "Circle Class"
 */

Creating groups as following also help for designing pages:

/** \defgroup groupCircleDefinition Circle Definition
 * A circle is a simple shape in Euclidean geometry.
 * It is the set of all points in a plane that are at a given distance from a given point, the centre;
 * equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant.
 * The distance between any of the points and the centre is called the radius.
 */

An example can be found here

on branchB do $git checkout branchA to switch to branch A

on branchA do $git merge branchB

That's all you need.

Use the pointtype and pointsize options, e.g.

plot "./points.dat" using 1:2 pt 7 ps 10  

where pt 7 gives you a filled circle and ps 10 is the size.

See: Plotting data.

It's something that "appears to the rest of the system to occur instantaneously", and falls under categorisation of Linearizability in computing processes. To quote that linked article further:

Atomicity is a guarantee of isolation from concurrent processes. Additionally, atomic operations commonly have a succeed-or-fail definition — they either successfully change the state of the system, or have no apparent effect.

So, for instance, in the context of a database system, one can have 'atomic commits', meaning that you can push a changeset of updates to a relational database and those changes will either all be submitted, or none of them at all in the event of failure, in this way data does not become corrupt, and consequential of locks and/or queues, the next operation will be a different write or a read, but only after the fact. In the context of variables and threading this is much the same, applied to memory.

Your quote highlights that this need not be expected behaviour in all instances.

You can do it using pageContext attributes, though:

In the JSP:

<form action="Enter.do">
    <button type="SUBMIT" id="btnSubmit" name="btnSubmit">SUBMIT</button>
</form>
<% String s="opportunity";
pageContext.setAttribute("opp", s, PageContext.APPLICATION_SCOPE); %>

In the Servlet (linked to the "Enter.do" url-pattern):

String s=(String) request.getServletContext().getAttribute("opp");

There are other scopes besides APPLICATION_SCOPE like SESSION_SCOPE. APPLICATION_SCOPE is used for ServletContext attributes.

i was having this same issue with ie, then i inserted this meta tag and it allowed me to edit the borders in ie

<meta http-equiv="X-UA-Compatible" content="IE=100" >

The accepted answer didn't work for me for two reasons:

1. I had BackColor set so setting AutoSize = false and Dock = Fill causes the background color to fill the whole form
2. I couldn't have AutoSize set to false anyway because my label text was dynamic

Instead, I simply used the form's width and the width of the label to calculate the left offset:

MyLabel.Left = (this.Width - MyLabel.Width) / 2;
