• None: The file is not included in the project output group and is not compiled in the build process. An example is a text file that contains documentation, such as a Readme file.

• Compile: The file is compiled into the build output. This setting is used for code files.

• Content: Allows you to retrieve a file (in the same directory as the assembly) as a stream via Application.GetContentStream(URI). For this method to work, it needs a AssemblyAssociatedContentFile custom attribute which Visual Studio graciously adds when you mark a file as "Content"

• Embedded resource: Embeds the file in an exclusive assembly manifest resource.

• Resource (WPF only): Embeds the file in a shared (by all files in the assembly with similar setting) assembly manifest resource named AppName.g.resources.

• Page (WPF only): Used to compile a xaml file into baml. The baml is then embedded with the same technique as Resource (i.e. available as `AppName.g.resources)

• ApplicationDefinition (WPF only): Mark the XAML/class file that defines your application. You specify the code-behind with the x:Class="Namespace.ClassName" and set the startup form/page with StartupUri="Window1.xaml"

• SplashScreen (WPF only): An image that is marked as SplashScreen is shown automatically when an WPF application loads, and then fades

• DesignData: Compiles XAML viewmodels so that usercontrols can be previewed with sample data in Visual Studio (uses mock types)

• DesignDataWithDesignTimeCreatableTypes: Compiles XAML viewmodels so that usercontrols can be previewed with sample data in Visual Studio (uses actual types)

• EntityDeploy: (Entity Framework): used to deploy the Entity Framework artifacts

• CodeAnalysisDictionary: An XML file containing custom word dictionary for spelling rules

can use html5 mark tag within paragraph and heading tag.

<p>lorem ipsum <mark>Highlighted Text</mark> dolor sit.</p>

You can use parseInt() but, as mentioned, the radix (base) should be specified:

x = parseInt(x, 10);
y = parseInt(y, 10);

10 means a base-10 number.

See this link for an explanation of why the radix is necessary.

You can't refresh without the warning; refresh instructs the browser to repeat the last action. It is up to the browser to choose whether to warn the user if repeating the last action involves resubmitting data.

You could re-navigate to the same page with a fresh session by doing:

window.location = window.location.href;

Since Java 8 release, there is more declarative way to initialize ThreadLocal:

ThreadLocal<Cipher> local = ThreadLocal.withInitial(() -> "init value");

Until Java 8 release you had to do the following:

ThreadLocal<String> local = new ThreadLocal<String>(){
    @Override
    protected String initialValue() {
        return "init value";
    }
};

Moreover, if instantiation method (constructor, factory method) of class that is used for ThreadLocal does not take any parameters, you can simply use method references (introduced in Java 8):

class NotThreadSafe {
    // no parameters
    public NotThreadSafe(){}
}

ThreadLocal<NotThreadSafe> container = ThreadLocal.withInitial(NotThreadSafe::new);

Note: Evaluation is lazy since you are passing java.util.function.Supplier lambda that is evaluated only when ThreadLocal#get is called but value was not previously evaluated.

( If your url is correct and still get that error messege ) Do following steps to setup the Classpath in netbeans,

1. Create a new folder in your project workspace and add the downloaded .jar file(eg:- mysql-connector-java-5.1.35-bin.jar )
2. Right click your project > properties > Libraries > ADD jar/Folder Select the jar file in that folder you just make. And click OK.

Now you will see that .jar file will be included under the libraries. Now you will not need to use the line, Class.forName("com.mysql.jdbc.Driver"); also.

If above method did not work, check the mysql-connector version (eg:- 5.1.35) and try a newer or a suitable version for you.

Use an overloaded method without the out parameter to call the one with the out parameter for C# 6.0 and lower. I'm not sure why a C# 7.0 for .NET Core is even the correct answer for this thread when it was specifically asked if C# 4.0 can have an optional out parameter. The answer is NO!

Try the following command:

This font is not standard on all devices. It is installed by default on some Macs, but rarely on PCs and mobile devices.

To use this font on all devices, use a @font-face declaration in your CSS to link to it on your domain if you wish to use it.

@font-face { font-family: Delicious; src: url('Delicious-Roman.otf'); } 
@font-face { font-family: Delicious; font-weight: bold; src: url('Delicious-Bold.otf'); }

with open('ZooDatabase.sql', 'r') as sql_file:
    conn.executescript(sql_file.read())

conn.close()

If you decided to write your hello.World class in Kotlin, another issue might be that you have to reference it as mainClassName = "hello.WorldKt".

package hello
fun main(args: Array<String>) {
    ...
}
// class World {} // this line is not necessary

<video id="myvideo">
  <source src="path/to/movie.mp4" />
</video>

<p onclick="toggleControls();">Toggle</p>

<script>
var video = document.getElementById("myvideo");

function toggleControls() {
  if (video.hasAttribute("controls")) {
     video.removeAttribute("controls")   
  } else {
     video.setAttribute("controls","controls")   
  }
}

if it is cluster MongoDB then you need to add your current IP to the cluster, to add your current IP address you need to complete few steps below-

step 1- go to login page of Mongodb and login with valid credential - https://cloud.mongodb.com/user#/atlas/login
step 2- CLick Network Access from left sidebar under Security Section
Step 3 - Click Add IP Address
Step 4 - Click Add Current IP Address or Allow Connection From Any Where
now try to connect - npm start

and for Local MongoDB use mongo String like "mongodb+srv://username:pass%[email protected]/test?retryWrites=true&w=majority"

password must be encoded like example string

You can use Cursor like that:

USE master
GO

DECLARE @SPID AS SMALLINT
DECLARE @Database AS VARCHAR(500)
SET @Database = 'AdventureWorks2016CTP3'

DECLARE Murderer CURSOR FOR
SELECT spid FROM sys.sysprocesses WHERE DB_NAME(dbid) = @Database

OPEN Murderer

FETCH NEXT FROM Murderer INTO @SPID
WHILE @@FETCH_STATUS = 0

    BEGIN
    SET @SQL = 'Kill ' + CAST(@SPID AS VARCHAR(10)) + ';'
    EXEC (@SQL)
    PRINT  ' Process ' + CAST(@SPID AS VARCHAR(10)) +' has been killed'
    FETCH NEXT FROM Murderer INTO @SPID
    END 

CLOSE Murderer
DEALLOCATE Murderer

You probably need to set your application as an x64 app.

The IIS Snap In only works in 64 bit and doesn't work in 32 bit, and a process spawned from a 32 bit app seems to work to be a 32 bit process and the same goes for 64 bit apps.

Look at: Start process as 64 bit

Just wanted to add another simple way someone can sort the the WPF ListView

void SortListView(ListView listView)
{
    IEnumerable listView_items = listView.Items.SourceCollection;
    List<MY_ITEM_CLASS> listView_items_to_list = listView_items.Cast<MY_ITEM_CLASS>().ToList();

    Comparer<MY_ITEM_CLASS> scoreComparer = Comparer<MY_ITEM_CLASS>.Create((first, second) => first.COLUMN_NAME.CompareTo(second.COLUMN_NAME));

    listView_items_to_list.Sort(scoreComparer);
    listView.ItemsSource = null;
    listView.Items.Clear();
    listView.ItemsSource = listView_items_to_list;
}

IF NOT EXISTS(select * FROM sys.views where name = 'data_VVVV ')
    BEGIN
        CREATE VIEW data_VVVV AS 
        SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
    END
ELSE
    BEGIN
        ALTER VIEW data_VVVV AS 
        SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
    END

If you don't care about the order of the K-th largest elements you can use argpartition, which should perform better than a full sort through argsort.

K = 4 # We want the indices of the four largest values
a = np.array([0, 8, 0, 4, 5, 8, 8, 0, 4, 2])
np.argpartition(a,-K)[-K:]
array([4, 1, 5, 6])

Credits go to this question.

I ran a few tests and it looks like argpartition outperforms argsort as the size of the array and the value of K increase.

Logical operators for boolean indexing in Pandas

It's important to realize that you cannot use any of the Python logical operators (and, or or not) on pandas.Series or pandas.DataFrames (similarly you cannot use them on numpy.arrays with more than one element). The reason why you cannot use those is because they implicitly call bool on their operands which throws an Exception because these data structures decided that the boolean of an array is ambiguous:

>>> import numpy as np
>>> import pandas as pd
>>> arr = np.array([1,2,3])
>>> s = pd.Series([1,2,3])
>>> df = pd.DataFrame([1,2,3])
>>> bool(arr)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
>>> bool(s)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> bool(df)
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

I did cover this more extensively in my answer to the "Truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()" Q+A.

NumPys logical functions

However NumPy provides element-wise operating equivalents to these operators as functions that can be used on numpy.array, pandas.Series, pandas.DataFrame, or any other (conforming) numpy.array subclass:

• and has np.logical_and
• or has np.logical_or
• not has np.logical_not
• numpy.logical_xor which has no Python equivalent but is a logical "exclusive or" operation

So, essentially, one should use (assuming df1 and df2 are pandas DataFrames):

np.logical_and(df1, df2)
np.logical_or(df1, df2)
np.logical_not(df1)
np.logical_xor(df1, df2)

Bitwise functions and bitwise operators for booleans

However in case you have boolean NumPy array, pandas Series, or pandas DataFrames you could also use the element-wise bitwise functions (for booleans they are - or at least should be - indistinguishable from the logical functions):

• bitwise and: np.bitwise_and or the & operator
• bitwise or: np.bitwise_or or the | operator
• bitwise not: np.invert (or the alias np.bitwise_not) or the ~ operator
• bitwise xor: np.bitwise_xor or the ^ operator

Typically the operators are used. However when combined with comparison operators one has to remember to wrap the comparison in parenthesis because the bitwise operators have a higher precedence than the comparison operators:

(df1 < 10) | (df2 > 10)  # instead of the wrong df1 < 10 | df2 > 10

This may be irritating because the Python logical operators have a lower precendence than the comparison operators so you normally write a < 10 and b > 10 (where a and b are for example simple integers) and don't need the parenthesis.

Differences between logical and bitwise operations (on non-booleans)

It is really important to stress that bit and logical operations are only equivalent for boolean NumPy arrays (and boolean Series & DataFrames). If these don't contain booleans then the operations will give different results. I'll include examples using NumPy arrays but the results will be similar for the pandas data structures:

>>> import numpy as np
>>> a1 = np.array([0, 0, 1, 1])
>>> a2 = np.array([0, 1, 0, 1])

>>> np.logical_and(a1, a2)
array([False, False, False,  True])
>>> np.bitwise_and(a1, a2)
array([0, 0, 0, 1], dtype=int32)

And since NumPy (and similarly pandas) does different things for boolean (Boolean or “mask” index arrays) and integer (Index arrays) indices the results of indexing will be also be different:

>>> a3 = np.array([1, 2, 3, 4])

>>> a3[np.logical_and(a1, a2)]
array([4])
>>> a3[np.bitwise_and(a1, a2)]
array([1, 1, 1, 2])

Summary table

Logical operator | NumPy logical function | NumPy bitwise function | Bitwise operator
-------------------------------------------------------------------------------------
       and       |  np.logical_and        | np.bitwise_and         |        &
-------------------------------------------------------------------------------------
       or        |  np.logical_or         | np.bitwise_or          |        |
-------------------------------------------------------------------------------------
                 |  np.logical_xor        | np.bitwise_xor         |        ^
-------------------------------------------------------------------------------------
       not       |  np.logical_not        | np.invert              |        ~

Where the logical operator does not work for NumPy arrays, pandas Series, and pandas DataFrames. The others work on these data structures (and plain Python objects) and work element-wise. However be careful with the bitwise invert on plain Python bools because the bool will be interpreted as integers in this context (for example ~False returns -1 and ~True returns -2).

What the guidelines say is that the public API should not reveal the internal design decision of whether you are using a list, a set, a dictionary, a tree or whatever. A "team" is not necessarily a list. You may implement it as a list but users of your public API should use you class on a need to know basis. This allows you to change your decision and use a different data structure without affecting the public interface.

I've made small modifications to @paul-H code, such that you can set the font size for the x/y axes and legend independently. Hope it helps:

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
x = np.random.normal(size=37)
y = np.random.lognormal(size=37)

# defaults                                                                                                         
sns.set()
fig, ax = plt.subplots()
ax.plot(x, y, marker='s', linestyle='none', label='small')
ax.legend(loc='upper left', fontsize=20,bbox_to_anchor=(0, 1.1))
ax.set_xlabel('X_axi',fontsize=20);
ax.set_ylabel('Y_axis',fontsize=20);

plt.show()

This is the output:

Try this

q = Session.query(
         User, Document, DocumentPermissions,
    ).filter(
         User.email == Document.author,
    ).filter(
         Document.name == DocumentPermissions.document,
    ).filter(
        User.email == 'someemail',
    ).all()

I built on @DavidLin's answer a little to simplify it - removing any dependency on jQuery in the directive. I can confirm this works as I use it in a production application

function AjaxLoadingOverlay($http) {

    return {
        restrict: 'A',
        link: function ($scope, $element, $attributes) {

            $scope.loadingOverlay = false;

            $scope.isLoading = function () {
                return $http.pendingRequests.length > 0;
            };

            $scope.$watch($scope.isLoading, function (isLoading) {
                $scope.loadingOverlay = isLoading;
            });
        }
    };
}   

I use a ng-show instead of a jQuery call to hide/show the <div>.

Here's the <div> which I placed just below the opening <body> tag:

<div ajax-loading-overlay class="loading-overlay" ng-show="loadingOverlay">
    <img src="Resources/Images/LoadingAnimation.gif" />
</div>

And here's the CSS that provides the overlay to block UI while a $http call is being made:

.loading-overlay {
    position: fixed;
    z-index: 999;
    height: 2em;
    width: 2em;
    overflow: show;
    margin: auto;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
}

.loading-overlay:before {
    content: '';
    display: block;
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: rgba(0,0,0,0.3);
}

/* :not(:required) hides these rules from IE9 and below */
.loading-overlay:not(:required) {
    font: 0/0 a;
    color: transparent;
    text-shadow: none;
    background-color: transparent;
    border: 0;
}

e.g.

 ColorTranslator.ToHtml(Color.FromArgb(Color.Tomato.ToArgb()))

This can avoid the KnownColor trick.

You should define the __unicode__ method on your model, and the template will call it automatically when you reference the instance.

You can use Union or Concat, the former removes duplicates, the later doesn't

foreach (var item in List1.Union(List1))
{
   //TODO: Real code goes here
}

foreach (var item in List1.Concat(List1))
{
   //TODO: Real code goes here
}

You need to use the file:/// protocol (yes, that's three slashes) if you want to link to local files.

<a href="file:///C:\Programs\sort.mw">Link 1</a>
<a href="file:///C:\Videos\lecture.mp4">Link 2</a>

These will never open the file in your local applications automatically. That's for security reasons which I'll cover in the last section. If it opens, it will only ever open in the browser. If your browser can display the file, it will, otherwise it will probably ask you if you want to download the file.

You cannot cross from http(s) to the file protocol

Modern versions of many browsers (e.g. Firefox and Chrome) will refuse to cross from the http(s) protocol to the file protocol to prevent malicious behaviour.

This means a webpage hosted on a website somewhere will never be able to link to files on your hard drive. You'll need to open your webpage locally using the file protocol if you want to do this stuff at all.

Why does it get stuck without file:///?

The first part of a URL is the protocol. A protocol is a few letters, then a colon and two slashes. HTTP:// and FTP:// are valid protocols; C:/ isn't and I'm pretty sure it doesn't even properly resemble one.

C:/ also isn't a valid web address. The browser could assume it's meant to be http://c/ with a blank port specified, but that's going to fail.

Your browser may not assume it's referring to a local file. It has little reason to make that assumption because webpages generally don't try to link to peoples' local files.

So if you want to access local files: tell it to use the file protocol.

Why three slashes?

Because it's part of the File URI scheme. You have the option of specifying a host after the first two slashes. If you skip specifying a host it will just assume you're referring to a file on your own PC. This means file:///C:/etc is a shortcut for file://localhost/C:/etc.

These files will still open in your browser and that is good

Your browser will respond to these files the same way they'd respond to the same file anywhere on the internet. These files will not open in your default file handler (e.g. MS Word or VLC Media Player), and you will not be able to do anything like ask File Explorer to open the file's location.

This is an extremely good thing for your security.

Sites in your browser cannot interact with your operating system very well. If a good site could tell your machine to open lecture.mp4 in VLC.exe, a malicious site could tell it to open virus.bat in CMD.exe. Or it could just tell your machine to run a few Uninstall.exe files or open File Explorer a million times.

This may not be convenient for you, but HTML and browser security weren't really designed for what you're doing. If you want to be able to open lecture.mp4 in VLC.exe consider writing a desktop application instead.

Problem

I specifically got the "[module_name]:prepareDebugUnitTestDependencies" task not found error, every time I ran gradle build. This happened to me after updating my Android Studio to 3.0.0.

Investigation

I had previously added command-line options to the gradle-based compiler, which you can find under: File -> Settings -> Build, Execution, Deployment -> Compiler -> Command-line Options. Specifically, I had excluded a number of tasks, including the aforementioned task. While that worked fine on the previous stable version (2.3 at that time), it seems like this was the reason behind the build failure.

Solution

This is one of many possible solutions. Make sure you have the correct command-line options specified in the settings under: File -> Settings -> Build, Execution, Deployment -> Compiler -> Command-line Options, and that none of them is causing this problem.

In my case, I removed the exclusion of this task (and other tasks that seemed related), left the unrelated tasks excluded, and it worked!

If you ARE using SQL Server, you can just simply wrap the square brackets around the column or table name.

select [select]
from [table]

Use FirstOrDefault. First will never return null - if it can't find a matching element it throws the exception you're seeing.

_dsACL.Documents.FirstOrDefault(o => o.ID == id);

I've set Lines = 0 on Storyboard, under Attribute Inspector and linked a referencing outlet to the label. Then use in controller like this:

 @IBOutlet weak var listLabel: UILabel!

 override func viewDidLoad() {
      ...
      listLabel.text = "Line 1\nLine 2\nLine 3\nLine 4\nLine 5\nLine 6\nLine 7\nLine 8"
 }

You can get a columns value by doing this

 rows["ColumnName"]

You will also have to cast to the appropriate type.

 output += (string)rows["ColumnName"]

Let said our backend looks like this:

public async Task<IActionResult> Post([FromBody] IList<UserRol> roles, string notes) {
}

We have a HttpService like this:

    post<T>(url: string, body: any, headers?: HttpHeaders, params?: HttpParams): Observable<T> {
        return this.http.post<T>(url, body, { headers: headers, params});
    }

Following is how we can pass the body and the notes as parameter: // how to call it

const headers: HttpHeaders = new HttpHeaders({
    'Authorization': `Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXX`
});

const bodyData = this.getBodyData(); // get whatever we want to send as body

let params: HttpParams = new HttpParams();
params = params.set('notes', 'Some notes to send');

this.httpService.post<any>(url, bodyData, headers, params);

It worked for me (using angular 7^), I hope is useful for somebody.

If you're using Eclipse PDT, this is done by opening up the PHP explorer view, then clicking the upside-down triangle in the top-right of that window. A context window appears, and the filters option is available there. Clicking the Filters menu option opens a new window, where .* files can be unchecked, thus allowing the editing of .htaccess files.

I searched forever for this, so I'm sorta answering my own question here. I'm sure someone else will have the same problem too, so I hope this helps someone else as well.

svn co svn://path destination

To specify current directory, use a "." for your destination directory:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

Usinge the file argument in the print function, you can have different files per print:

print('Redirect output to file', file=open('/tmp/example.log', 'w'))

You can use the opt(int) method and use a classical for loop.

pdf2ps large.pdf small.pdf is enough, instead of two steps

pdf2ps large.pdf very_large.ps 
ps2pdf very_large.ps small.pdf

However, ps2pdf large.pdf small.pdf is a better choice.

• ps2pdf is much faster
• without additional parameters specified, pdf2ps sometimes produces larger file.

References are not pointers.

8.3.2/1:

A reference shall be initialized to refer to a valid object or function. [Note: in particular, a null reference cannot exist in a well-defined program, because the only way to create such a reference would be to bind it to the “object” obtained by dereferencing a null pointer, which causes undefined behavior. As described in 9.6, a reference cannot be bound directly to a bit-field. ]

1.9/4:

Certain other operations are described in this International Standard as undefined (for example, the effect of dereferencing the null pointer)

As Johannes says in a deleted answer, there's some doubt whether "dereferencing a null pointer" should be categorically stated to be undefined behavior. But this isn't one of the cases that raise doubts, since a null pointer certainly does not point to a "valid object or function", and there is no desire within the standards committee to introduce null references.

x.length-4 only accounts for extensions of 3 characters. What if you have filename.jpegor filename.pl?

EDIT:

To answer... sure, if you always have an extension of .jpg, x.length-4 would work just fine.

However, if you don't know the length of your extension, any of a number of solutions are better/more robust.

x = x.replace(/\..+$/, '');

OR

x = x.substring(0, x.lastIndexOf('.'));

OR

x = x.replace(/(.*)\.(.*?)$/, "$1");

OR (with the assumption filename only has one dot)

parts = x.match(/[^\.]+/);
x = parts[0];

OR (also with only one dot)

parts = x.split(".");
x = parts[0];

This is the code I'm using. Also works for .NET Core > 2.0 using System.Drawing.Common NuGet.

https://www.nuget.org/packages/System.Drawing.Common/

using System;
using System.Drawing;

class Program
{
    static void Main()
    {
        const string input = "C:\\background1.png";
        const string output = "C:\\thumbnail.png";

        // Load image.
        Image image = Image.FromFile(input);

        // Compute thumbnail size.
        Size thumbnailSize = GetThumbnailSize(image);

        // Get thumbnail.
        Image thumbnail = image.GetThumbnailImage(thumbnailSize.Width,
            thumbnailSize.Height, null, IntPtr.Zero);

        // Save thumbnail.
        thumbnail.Save(output);
    }

    static Size GetThumbnailSize(Image original)
    {
        // Maximum size of any dimension.
        const int maxPixels = 40;

        // Width and height.
        int originalWidth = original.Width;
        int originalHeight = original.Height;

        // Return original size if image is smaller than maxPixels
        if (originalWidth <= maxPixels || originalHeight <= maxPixels)
        {
            return new Size(originalWidth, originalHeight);
        }   

        // Compute best factor to scale entire image based on larger dimension.
        double factor;
        if (originalWidth > originalHeight)
        {
            factor = (double)maxPixels / originalWidth;
        }
        else
        {
            factor = (double)maxPixels / originalHeight;
        }

        // Return thumbnail size.
        return new Size((int)(originalWidth * factor), (int)(originalHeight * factor));
    }
}

• Xcode Version 10.2.1 (10E1001)
• Swift 5
• Alamofire 4.8.2

Solution

import Alamofire

struct BodyStringEncoding: ParameterEncoding {

    private let body: String

    init(body: String) { self.body = body }

    func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        guard var urlRequest = urlRequest.urlRequest else { throw Errors.emptyURLRequest }
        guard let data = body.data(using: .utf8) else { throw Errors.encodingProblem }
        urlRequest.httpBody = data
        return urlRequest
    }
}

extension BodyStringEncoding {
    enum Errors: Error {
        case emptyURLRequest
        case encodingProblem
    }
}

extension BodyStringEncoding.Errors: LocalizedError {
    var errorDescription: String? {
        switch self {
            case .emptyURLRequest: return "Empty url request"
            case .encodingProblem: return "Encoding problem"
        }
    }
}

Usage

Alamofire.request(url, method: .post, parameters: nil, encoding: BodyStringEncoding(body: text), headers: headers).responseJSON { response in
     print(response)
}

I always used the above solution without searching more after this. ;-)

However, today I came across something and thought of sharing it. :)

This feature is indeed available from API 1 and is called as ColorStateList, where we can supply a color to various states of Widgets (as we already know).

It is also very well documented, here.

I keep it as simple as possible (for me at least)

Enumerations

Constructors
Overrides
Methods
Properties
Event Handler

The way in which the amount of storage space required by an algorithm varies with the size of the problem it is solving. Space complexity is normally expressed as an order of magnitude, e.g. O(N^2) means that if the size of the problem (N) doubles then four times as much working storage will be needed.

how about this?

If you are using IntelliJ IDE just right click on resources package and go to new and then select Resource Boundle it automatically create a .properties file for you. This did work for me .

import os
import os.path
import shutil

You find your current directory:

d = os.getcwd() #Gets the current working directory

Then you change one directory up:

os.chdir("..") #Go up one directory from working directory

Then you can get a tupple/list of all the directories, for one directory up:

o = [os.path.join(d,o) for o in os.listdir(d) if os.path.isdir(os.path.join(d,o))] # Gets all directories in the folder as a tuple

Then you can search the tuple for the directory you want and open the file in that directory:

for item in o:
    if os.path.exists(item + '\\testfile.txt'):
    file = item + '\\testfile.txt'

Then you can do stuf with the full file path 'file'

The example below shows the basic usage of the FileReader to read the contents of an uploaded file. Here is a working Plunker of this example.

<!DOCTYPE html>
<html>
  <head>
    <script src="script.js"></script>
  </head>

  <body onload="init()">
    <input id="fileInput" type="file" name="file" />
    <pre id="fileContent"></pre>
  </body>
</html>

script.js

function init(){
  document.getElementById('fileInput').addEventListener('change', handleFileSelect, false);
}

function handleFileSelect(event){
  const reader = new FileReader()
  reader.onload = handleFileLoad;
  reader.readAsText(event.target.files[0])
}

function handleFileLoad(event){
  console.log(event);
  document.getElementById('fileContent').textContent = event.target.result;
}

You can use OR() to group expressions (as well as AND()):

=IF(OR(condition1, condition2), true, false)

=IF(AND(condition1, condition2), true, false)

So if you wanted to test for "cat" and "22":

=IF(AND(SEARCH("cat",a1),SEARCH("22",a1)),"cat and 22","none")

Sure you can. Something like:

HTML

<div ng-controller="fessCntrl">    
     <label ng-repeat="(key,val) in list">
       <input type="radio" name="localityTypeRadio" ng-model="$parent.localityTypeRadio" ng-value="key" />{{key}}
         <div ng-if="key == 'City' || key == 'County'">
             <pre>City or County !!! {{$parent.localityTypeRadio}}</pre>
         </div>
         <div ng-if="key == 'Town'">
             <pre>Town!!! {{$parent.localityTypeRadio}}</pre>
         </div>        
      </label>
</div>

JS

var fessmodule = angular.module('myModule', []);

fessmodule.controller('fessCntrl', function ($scope) {

    $scope.list = {
        City: [{name: "cityA"}, {name: "cityB"}],
        County: [{ name: "countyA"}, {name: "countyB"}],
        Town: [{ name: "townA"}, {name: "townB"}]
      };

    $scope.localityTypeRadio = 'City';
});

fessmodule.$inject = ['$scope'];

Demo Fiddle

This can be done. Following are the steps to setup the GUI

Create new user with password login

sudo useradd -m awsgui
sudo passwd awsgui
sudo usermod -aG admin awsgui

sudo vim /etc/ssh/sshd_config # edit line "PasswordAuthentication" to yes

sudo /etc/init.d/ssh restart

Setting up ui based ubuntu machine on AWS.

In security group open port 5901. Then ssh to the server instance. Run following commands to install ui and vnc server:

sudo apt-get update
sudo apt-get install ubuntu-desktop
sudo apt-get install vnc4server

Then run following commands and enter the login password for vnc connection:

su - awsgui

vncserver

vncserver -kill :1

vim /home/awsgui/.vnc/xstartup

Then hit the Insert key, scroll around the text file with the keyboard arrows, and delete the pound (#) sign from the beginning of the two lines under the line that says "Uncomment the following two lines for normal desktop." And on the second line add "sh" so the line reads

exec sh /etc/X11/xinit/xinitrc. 

When you're done, hit Ctrl + C on the keyboard, type :wq and hit Enter.

Then start vnc server again.

vncserver

You can download xtightvncviewer to view desktop(for Ubutnu) from here https://help.ubuntu.com/community/VNC/Clients

In the vnc client, give public DNS plus ":1" (e.g. www.example.com:1). Enter the vnc login password. Make sure to use a normal connection. Don't use the key files.

Additional guide available here: http://www.serverwatch.com/server-tutorials/setting-up-vnc-on-ubuntu-in-the-amazon-ec2-Page-3.html

Mac VNC client can be downloaded from here: https://www.realvnc.com/en/connect/download/viewer/

Port opening on console

sudo iptables -A INPUT -p tcp --dport 5901 -j ACCEPT

If the grey window issue comes. Mostly because of ".vnc/xstartup" file on different user. So run the vnc server also on same user instead of "awsgui" user.

vncserver

If you are using wamp server then go to icon click on this

Then go to PHP then click on PHP extension there would be php_openssl need to activate from there and restart wamp server

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;

• How to get total RAM size of a device?

This getMemorySize() method is returned MemorySize that has total and free memory size.
I don't believe this code perfectly.
This code is testing on LG G3 cat.6 (v5.0.1)

    private MemorySize getMemorySize() {
        final Pattern PATTERN = Pattern.compile("([a-zA-Z]+):\\s*(\\d+)");

        MemorySize result = new MemorySize();
        String line;
        try {
            RandomAccessFile reader = new RandomAccessFile("/proc/meminfo", "r");
            while ((line = reader.readLine()) != null) {
                Matcher m = PATTERN.matcher(line);
                if (m.find()) {
                    String name = m.group(1);
                    String size = m.group(2);

                    if (name.equalsIgnoreCase("MemTotal")) {
                        result.total = Long.parseLong(size);
                    } else if (name.equalsIgnoreCase("MemFree") || name.equalsIgnoreCase("Buffers") ||
                            name.equalsIgnoreCase("Cached") || name.equalsIgnoreCase("SwapFree")) {
                        result.free += Long.parseLong(size);
                    }
                }
            }
            reader.close();

            result.total *= 1024;
            result.free *= 1024;
        } catch (IOException e) {
            e.printStackTrace();
        }

        return result;
    }

    private static class MemorySize {
        public long total = 0;
        public long free = 0;
    }

I know that Pattern.compile() is expensive cost so You may move its code to class member.

This is a common question. In base, the option you're looking for is aggregate. Assuming your data.frame is called "mydf", you can use the following.

> aggregate(B ~ A, mydf, sum)
  A  B
1 1  5
2 2  3
3 3 11

I would also recommend looking into the "data.table" package.

> library(data.table)
> DT <- data.table(mydf)
> DT[, sum(B), by = A]
   A V1
1: 1  5
2: 2  3
3: 3 11

You can safely delete the table manually or using query. It will be recreated automatically.

DROP TABLE DATABASECHANGELOGLOCK;

The solution I've found was:

$text = 'Line one\n\nLine two');
$text = explode('\n', $text);

foreach ($text as $txt){
    $pdf->Write($txt);
    $pdf->Ln();
}

So this way, you may have any number of \n in any position, if you're getting this text dinamically from the database, it will break lines correctrly.

NSString *str = @"hello";
NSData *data = [NSData dataWithBytes:str.UTF8String length:str.length];

You can do like below:

var command = "Put your command here";
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.WorkingDirectory = @"C:\Program Files\IIS\Microsoft Web Deploy V3";
procStartInfo.CreateNoWindow = true; //whether you want to display the command window
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
string result = proc.StandardOutput.ReadToEnd();
label1.Text = result.ToString();

If you have a PPK file working on a PC, then export it as OpenSSH file using puttygen.exe for PC and use that on Mac (any Unix machine).

I was getting the same error --

debug1: read PEM private key done: type RSA
debug1: Authentications that can continue: publickey,gssapi-with-mic
debug1: No more authentication methods to try.

As I was using a PPK file on Windows, I followed the steps as described above and Bingo!

$ ssh -i ec2-openssh-key root@ec2-instance-ip

To check if the property exists and if it's null too, you can use the function property_exists().

Docs: http://php.net/manual/en/function.property-exists.php

As opposed with isset(), property_exists() returns TRUE even if the property has the value NULL.

bool property_exists ( mixed $class , string $property )

Example:

if (property_exists($testObject, $property)) {
    //do something
}

This will be the best way, to set the timeout for each service (passing timeout as parameter)

public static Retrofit getClient(String baseUrl, int serviceTimeout) {
        Retrofit retrofitselected = baseUrl.contains("http:") ? retrofit : retrofithttps;
        if (retrofitselected == null || retrofitselected.equals(retrofithttps)) {
            retrofitselected = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create(getGson().create()))
                    .client(!BuildConfig.FLAVOR.equals("PRE") ? new OkHttpClient.Builder()
                            .addInterceptor(new ResponseInterceptor())
                            .connectTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                            .writeTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                            .readTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                            .build() : getUnsafeOkHttpClient(serviceTimeout))
                    .build();
        }
        return retrofitselected;
    }

And dont miss this for OkHttpClient.

private static OkHttpClient getUnsafeOkHttpClient(int serviceTimeout) {
        try {
            // Create a trust manager that does not validate certificate chains
            final TrustManager[] trustAllCerts = new TrustManager[] {

                        }

                        @Override
                        public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public java.security.cert.X509Certificate[] getAcceptedIssuers() {

            final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

            OkHttpClient.Builder builder = new OkHttpClient.Builder();

For random hash values, some engineers said golden ratio prime number(2654435761) is a bad choice, with my testing results, I found that it's not true; instead, 2654435761 distributes the hash values pretty good.

#define MCR_HashTableSize 2^10

unsigned int
Hash_UInt_GRPrimeNumber(unsigned int key)
{
  key = key*2654435761 & (MCR_HashTableSize - 1)
  return key;
}

The hash table size must be a power of two.

I have written a test program to evaluate many hash functions for integers, the results show that GRPrimeNumber is a pretty good choice.

I have tried:

1. total_data_entry_number / total_bucket_number = 2, 3, 4; where total_bucket_number = hash table size;
2. map hash value domain into bucket index domain; that is, convert hash value into bucket index by Logical And Operation with (hash_table_size - 1), as shown in Hash_UInt_GRPrimeNumber();
3. calculate the collision number of each bucket;
4. record the bucket that has not been mapped, that is, an empty bucket;
5. find out the max collision number of all buckets; that is, the longest chain length;

With my testing results, I found that Golden Ratio Prime Number always has the fewer empty buckets or zero empty bucket and the shortest collision chain length.

Some hash functions for integers are claimed to be good, but the testing results show that when the total_data_entry / total_bucket_number = 3, the longest chain length is bigger than 10(max collision number > 10), and many buckets are not mapped(empty buckets), which is very bad, compared with the result of zero empty bucket and longest chain length 3 by Golden Ratio Prime Number Hashing.

BTW, with my testing results, I found one version of shifting-xor hash functions is pretty good(It's shared by mikera).

unsigned int Hash_UInt_M3(unsigned int key)
{
  key ^= (key << 13);
  key ^= (key >> 17);    
  key ^= (key << 5); 
  return key;
}

Instructions for Drupal 8 / FontAwesome 5

Create a YOUR_THEME_NAME_HERE.THEME file and place it in your themes directory (ie. your_site_name/themes/your_theme_name)

Paste this into the file, it is PHP code to find the Search Block and change the value to the UNICODE for the FontAwesome icon. You can find other characters at this link https://fontawesome.com/cheatsheet.

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
}
?>

Open the CSS file of your theme (ie. your_site_name/themes/your_theme_name/css/styles.css) and then paste this in which will change all input submit text to FontAwesome. Not sure if this will work if you also want to add text in the input button though for just an icon it is fine.

Make sure you import FontAwesome, add this at the top of the CSS file

@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

then add this in the CSS

input#edit-submit {
    font-family: 'Font Awesome\ 5 Free';
    background-color: transparent;
    border: 0;  
}

FLUSH ALL CACHES AND IT SHOULD WORK FINE

Add Google Font Effects

If you are using Google Web Fonts as well you can add also add effects to the icon (see more here https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta). You need to import a Google Web Font including the effect(s) you would like to use first in the CSS so it will be

@import url('https://fonts.googleapis.com/css?family=Open+Sans:400,800&effect=3d-float');
@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

Then go back to your .THEME file and add the class for the 3D Float Effect so the code will now add a class to the input. There are different effects available. So just choose the effect you like, change the CSS for the font import and the change the value FONT-EFFECT-3D-FLOAT int the code below to font-effect-WHATEVER_EFFECT_HERE. Note effects are still in Beta and don't work in all browsers so read here before you try it https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
  $form['actions']['submit']['#attributes']['class'][] = 'font-effect-3d-float';
}
?>

select num from table where ( num % 2 ) = 0

The optional SECOND argument is the index, starting at 0. So to output the index and total length of an array called 'some_list':

<div>Total Length: {{some_list.length}}</div>
<div v-for="(each, i) in some_list">
  {{i + 1}} : {{each}}
</div>

If instead of a list, you were looping through an object, then the second argument is key of the key/value pair. So for the object 'my_object':

var an_id = new Vue({
  el: '#an_id',
  data: {
    my_object: {
        one: 'valueA',
        two: 'valueB'
    }
  }
})

The following would print out the key : value pairs. (you can name 'each' and 'i' whatever you want)

<div id="an_id">
  <span v-for="(each, i) in my_object">
    {{i}} : {{each}}<br/>
  </span>
</div>

ModelName::find($id, ['name', 'surname']);

This works fine with ./self.sh, ~/self.sh, source self.sh, source ~/self.sh:

#!/usr/bin/env bash

self=$(readlink -f "${BASH_SOURCE[0]}")
basename=$(basename "$self")

echo "$self"
echo "$basename"

Credits: I combined multiple answers to get this one.

Thought I'd share this code. It's fairly simple, but effective. It parses comma-separated files with parenthesis. You can easily modify it to suit your needs.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>


int main(int argc, char *argv[])
{
  //argv[1] path to csv file
  //argv[2] number of lines to skip
  //argv[3] length of longest value (in characters)

  FILE *pfinput;
  unsigned int nSkipLines, currentLine, lenLongestValue;
  char *pTempValHolder;
  int c;
  unsigned int vcpm; //value character marker
  int QuotationOnOff; //0 - off, 1 - on

  nSkipLines = atoi(argv[2]);
  lenLongestValue = atoi(argv[3]);

  pTempValHolder = (char*)malloc(lenLongestValue);  

  if( pfinput = fopen(argv[1],"r") ) {

    rewind(pfinput);

    currentLine = 1;
    vcpm = 0;
    QuotationOnOff = 0;

    //currentLine > nSkipLines condition skips ignores first argv[2] lines
    while( (c = fgetc(pfinput)) != EOF)
    {
       switch(c)
       {
          case ',':
            if(!QuotationOnOff && currentLine > nSkipLines) 
            {
              pTempValHolder[vcpm] = '\0';
              printf("%s,",pTempValHolder);
              vcpm = 0;
            }
            break;
          case '\n':
            if(currentLine > nSkipLines)
            {
              pTempValHolder[vcpm] = '\0';
              printf("%s\n",pTempValHolder);
              vcpm = 0;
            }
            currentLine++;
            break;
          case '\"':
            if(currentLine > nSkipLines)
            {
              if(!QuotationOnOff) {
                QuotationOnOff = 1;
                pTempValHolder[vcpm] = c;
                vcpm++;
              } else {
                QuotationOnOff = 0;
                pTempValHolder[vcpm] = c;
                vcpm++;
              }
            }
            break;
          default:
            if(currentLine > nSkipLines)
            {
              pTempValHolder[vcpm] = c;
              vcpm++;
            }
            break;
       }
    }

    fclose(pfinput); 
    free(pTempValHolder);

  }

  return 0;
}

Simplest way to do this is:

import boto3
s3 = boto3.resource("s3")
bucket_source = {
            'Bucket': "my-bcuket",
            'Key': "file_path_in_bucket"
        }
s3.meta.client.delete(bucket_source)

The Interface of Postman is changing acccording to the updates.

So You can get full information about postman can get Here.

A bit of encoding can solve this:

Client Side:

message = input("->")
clientSocket.sendto(message.encode('utf-8'), (address, port))

Server Side:

data = s.recv(1024)
modifiedMessage, serverAddress = clientSocket.recvfrom(message.decode('utf-8'))

Store the value of the scroll as changes in HiddenField when around the PostBack retrieves the value and adds the scroll.

//jQuery

jQuery(document).ready(function () {

    $(window).scrollTop($("#<%=hidScroll.ClientID %>").val());

    $(window).scroll(function (event) {
        $("#<%=hidScroll.ClientID %>").val($(window).scrollTop());
    });
});

var prm = Sys.WebForms.PageRequestManager.getInstance();

prm.add_endRequest(function () {

    $(window).scrollTop($("#<%=hidScroll.ClientID %>").val());

    $(window).scroll(function (event) {
        $("#<%=hidScroll.ClientID %>").val($(window).scrollTop());
    });
});

//Page Asp.Net
<asp:HiddenField ID="hidScroll" runat="server" Value="0" />

Create a method to recursively iterate through nested lists. If the current element is an instance of list, then call the same method again. If not, print the current element. Here's an example:

data = [1,2,3,[4,[5,6,7,[8,9]]]]

def print_list(the_list):

    for each_item in the_list:
        if isinstance(each_item, list):
            print_list(each_item)
        else:
            print(each_item)

print_list(data)

Whilst not disagreeing with the complex answers about half-way marks and so on, for the more common (and possibly trivial) use-case:

my $rounded = int($float + 0.5);

UPDATE

If it's possible for your $float to be negative, the following variation will produce the correct result:

my $rounded = int($float + $float/abs($float*2 || 1));

With this calculation -1.4 is rounded to -1, and -1.6 to -2, and zero won't explode.

Use round() (use if you are expecting a number in float format only, else use number_format() as an answer given by Codemwnci):

echo round(520.34345, 2);   // 520.34
echo round(520.3, 2);       // 520.3
echo round(520, 2);         // 520

From the manual:

Description:

float round(float $val [, int $precision = 0 [, int $mode = PHP_ROUND_HALF_UP ]]);

Returns the rounded value of val to specified precision (number of digits after the decimal point). precision can also be negative or zero (default).

...

Example #1 round() examples

<?php
    echo round(3.4);         // 3
    echo round(3.5);         // 4
    echo round(3.6);         // 4
    echo round(3.6, 0);      // 4
    echo round(1.95583, 2);  // 1.96
    echo round(1241757, -3); // 1242000
    echo round(5.045, 2);    // 5.05
    echo round(5.055, 2);    // 5.06
?>

Example #2 mode examples

<?php
    echo round(9.5, 0, PHP_ROUND_HALF_UP);   // 10
    echo round(9.5, 0, PHP_ROUND_HALF_DOWN); // 9
    echo round(9.5, 0, PHP_ROUND_HALF_EVEN); // 10
    echo round(9.5, 0, PHP_ROUND_HALF_ODD);  // 9

    echo round(8.5, 0, PHP_ROUND_HALF_UP);   // 9
    echo round(8.5, 0, PHP_ROUND_HALF_DOWN); // 8
    echo round(8.5, 0, PHP_ROUND_HALF_EVEN); // 8
    echo round(8.5, 0, PHP_ROUND_HALF_ODD);  // 9
?>

I have hit this problem in the past - from the look of it if you don't actually need the clipboard at the point that you exit, so you can use the same simple solution I had. Just clear the clipboard. :)

ActiveCell.Copy

The Bundle is a container for all the information you want to save. You use the put* functions to insert data into it. Here's a short list (there are more) of put functions you can use to store data in the Bundle.

putString
putBoolean
putByte
putChar
putFloat
putLong
putShort
putParcelable (used for objects but they must implement Parcelable)

In your onCreate function, this Bundle is handed back to the program. The best way to check if the application is being reloaded, or started for the first time is:

if (savedInstanceState != null) {
    // Then the application is being reloaded
}

To get the data back out, use the get* functions just like the put* functions. The data is stored as a name-value pair. This is like a hashmap. You provide a key and the value, then when you want the value back, you give the key and the function gets the value. Here's a short example.

@Override
public void onSaveInstanceState(Bundle outState) {
   outState.putString("message", "This is my message to be reloaded");
   super.onSaveInstanceState(outState);
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (savedInstanceState != null) {
        String message = savedInstanceState.getString("message");
        Toast.makeText(this, message, Toast.LENGTH_LONG).show();
    }
}

Your saved message will be toasted to the screen. Hope this helps.

Pay attention: you cannot install arbitrary versions of tensorflow, they have to correspond to your python installation, which isn't conveyed by most of the answers here. This is also true for the current wheels like https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.1.0-cp35-cp35m-win_amd64.whl (from this answer above). For this example, the cp35-cp35m hints that it is for Python 3.5.x

A huge list of different wheels/compatibilities can be found here on github. By using this, you can downgrade to almost every availale version in combination with the respective for python. For example:

pip install tensorflow==2.0.0

(note that previous to installing Python 3.7.8 alongside version 3.8.3 in my case, you would get

ERROR: Could not find a version that satisfies the requirement tensorflow==2.0.0 (from versions: 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.3.0rc0, 2.3.0rc1)
ERROR: No matching distribution found for tensorflow==2.0.0

this also holds true for other non-compatible combinations.)

This should also be useful for legacy CPU without AVX support or GPUs with a compute capability that's too low.

If you only need the most recent releases (which it doesn't sound like in your question) a list of urls for the current wheel packages is available on this tensorflow page. That's from this SO-answer.

Note: This link to a list of different versions didn't work for me.

If you want to reassign an element in an array, you can do the following:

var blah = ['Jan', 'Fed', 'Apr'];

console.log(blah);

function reassign(array, index, newValue) {
    array[index] = newValue;
    return array;
}

reassign(blah, [2], 'Mar');

They have slightly different purposes.

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

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

DFS(analysis):

• Setting/getting a vertex/edge label takes O(1) time
• Each vertex is labeled twice
  • once as UNEXPLORED
  • once as VISITED
• Each edge is labeled twice
  • once as UNEXPLORED
  • once as DISCOVERY or BACK
• Method incidentEdges is called once for each vertex
• DFS runs in O(n + m) time provided the graph is represented by the adjacency list structure
• Recall that Sv deg(v) = 2m

BFS(analysis):

• Setting/getting a vertex/edge label takes O(1) time
• Each vertex is labeled twice
  • once as UNEXPLORED
  • once as VISITED
• Each edge is labeled twice
  • once as UNEXPLORED
  • once as DISCOVERY or CROSS
• Each vertex is inserted once into a sequence Li
• Method incidentEdges is called once for each vertex
• BFS runs in O(n + m) time provided the graph is represented by the adjacency list structure
• Recall that Sv deg(v) = 2m

Most GUIs assume that if you are in a directory and "open", double-click, or otherwise attempt to execute an .R file, that the directory in which it resides will be the working directory unless otherwise specified. The Mac GUI provides a method to change that default behavior which is changeable in the Startup panel of Preferences that you set in a running session and become effective at the next "startup". You should be also looking at:

?Startup

The RStudio documentation says:

"When launched through a file association, RStudio automatically sets the working directory to the directory of the opened file." The default setup is for RStudio to be register as a handler for .R files, although there is also mention of ability to set a default "association" with RStudio for .Rdata and .R extensions. Whether having 'handler' status and 'association' status are the same on Linux, I cannot tell.

http://www.rstudio.com/ide/docs/using/workspaces

You can also do something like that:

<error-page>
    <error-code>403</error-code>
    <location>/403.html</location>
</error-page>

<error-page>
    <location>/error.html</location>
</error-page>

For error code 403 it will return the page 403.html, and for any other error code it will return the page error.html.

You will need to have a datetime column in a table. Then you can do an insert like the following to insert the current date:

INSERT INTO MyTable (MyDate) Values (GetDate())

If it is not today's date then you should be able to use a string and specify the date format:

INSERT INTO MyTable (MyDate) Values (Convert(DateTime,'19820626',112)) --6/26/1982

You do not always need to convert the string either, often you can just do something like:

INSERT INTO MyTable (MyDate) Values ('06/26/1982') 

And SQL Server will figure it out for you.

I have been composing my Jersey 1.17 services the following way:

FileStreamingOutput

public class FileStreamingOutput implements StreamingOutput {

    private File file;

    public FileStreamingOutput(File file) {
        this.file = file;
    }

    @Override
    public void write(OutputStream output)
            throws IOException, WebApplicationException {
        FileInputStream input = new FileInputStream(file);
        try {
            int bytes;
            while ((bytes = input.read()) != -1) {
                output.write(bytes);
            }
        } catch (Exception e) {
            throw new WebApplicationException(e);
        } finally {
            if (output != null) output.close();
            if (input != null) input.close();
        }
    }

}

GET

@GET
@Produces("application/pdf")
public StreamingOutput getPdf(@QueryParam(value="name") String pdfFileName) {
    if (pdfFileName == null)
        throw new WebApplicationException(Response.Status.BAD_REQUEST);
    if (!pdfFileName.endsWith(".pdf")) pdfFileName = pdfFileName + ".pdf";

    File pdf = new File(Settings.basePath, pdfFileName);
    if (!pdf.exists())
        throw new WebApplicationException(Response.Status.NOT_FOUND);

    return new FileStreamingOutput(pdf);
}

And the client, if you need it:

Client

private WebResource resource;

public InputStream getPDFStream(String filename) throws IOException {
    ClientResponse response = resource.path("pdf").queryParam("name", filename)
        .type("application/pdf").get(ClientResponse.class);
    return response.getEntityInputStream();
}

Had this problem too and found out that the easiest way is to point your domain to the public folder and leave everything else the way they are.

PLEASE ENSURE TO USE THE RIGHT VERSION OF PHP. Save yourself some stress :)

This is a function for calculating max valid length for varchar(Nn):

CREATE FUNCTION [dbo].[GetMaxVarcharColumnLength] (@TableSchema NVARCHAR(MAX), @TableName NVARCHAR(MAX), @ColumnName VARCHAR(MAX))
RETURNS INT
AS
BEGIN
    RETURN (SELECT character_maximum_length FROM information_schema.columns  
            WHERE table_schema = @TableSchema AND table_name = @TableName AND column_name = @ColumnName);
END

Usage:

IF LEN(@Name) > [dbo].[GetMaxVarcharColumnLength]('person', 'FamilyStateName', 'Name') 
            RETURN [dbo].[err_Internal_StringForVarcharTooLong]();

If you want to clear all item you stored in localStorage then

localStorage.clear();

Use this for clear all stored key.

If you want to clear/remove only specific key/value then you can use removeItem(key).

localStorage.removeItem('yourKey');

all you need is to tie the group to a different item in your model

@Html.RadioButtonFor(x => x.Field1, "Milk")
@Html.RadioButtonFor(x => x.Field1, "Butter")

@Html.RadioButtonFor(x => x.Field2, "Water")
@Html.RadioButtonFor(x => x.Field2, "Beer")

Try to use toISOString(). It returns string in ISO8601 format.

from javascript

$.get('/example/doGet?date=' + new Date().toISOString(), function (result) {
    console.log(result);
});

from c#

[HttpGet]
public JsonResult DoGet(DateTime date)
{
    return Json(date.ToString(), JsonRequestBehavior.AllowGet);
}

In order to do this without FuncAnimation (eg you want to execute other parts of the code while the plot is being produced or you want to be updating several plots at the same time), calling draw alone does not produce the plot (at least with the qt backend).

The following works for me:

import matplotlib.pyplot as plt
plt.ion()
class DynamicUpdate():
    #Suppose we know the x range
    min_x = 0
    max_x = 10

    def on_launch(self):
        #Set up plot
        self.figure, self.ax = plt.subplots()
        self.lines, = self.ax.plot([],[], 'o')
        #Autoscale on unknown axis and known lims on the other
        self.ax.set_autoscaley_on(True)
        self.ax.set_xlim(self.min_x, self.max_x)
        #Other stuff
        self.ax.grid()
        ...

    def on_running(self, xdata, ydata):
        #Update data (with the new _and_ the old points)
        self.lines.set_xdata(xdata)
        self.lines.set_ydata(ydata)
        #Need both of these in order to rescale
        self.ax.relim()
        self.ax.autoscale_view()
        #We need to draw *and* flush
        self.figure.canvas.draw()
        self.figure.canvas.flush_events()

    #Example
    def __call__(self):
        import numpy as np
        import time
        self.on_launch()
        xdata = []
        ydata = []
        for x in np.arange(0,10,0.5):
            xdata.append(x)
            ydata.append(np.exp(-x**2)+10*np.exp(-(x-7)**2))
            self.on_running(xdata, ydata)
            time.sleep(1)
        return xdata, ydata

d = DynamicUpdate()

CSS is designed to describe the presentation of documents. It has a few features for changing that presentation in reaction to user interaction (primarily :hover for indicating that you are now pointing at something interactive).

Making something draggable isn't a simple matter of presentation. It is firmly in the territory of interactivity logic, which is handled by JavaScript.

What you want is not achievable.

On Mac OS you have to press: CMD+ALT+I

    var h, s, l = (max + min) / 2;

    if(max == min){
        h = s = 0; // achromatic
    }else{
        var d = max - min;
        s = l > 0.5 ? d / (2 - max - min) : d / (max + min);
        switch(max){
            case r: h = (g - b) / d + (g < b ? 6 : 0); break;
            case g: h = (b - r) / d + 2; break;
            case b: h = (r - g) / d + 4; break;
        }
        h /= 6;
    }

    return [h, s, l];
}

I believe .clone() is what you're looking for, so long as the class supports it.

In my case I missed the compile tag in the .csproj file

<Compile Include="Global.asax.cs">
  <DependentUpon>Global.asax</DependentUpon>
  <CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Compile>

I had similar expirience like yours. I have Denwer server. When I loaded my http://new.new local site without using via script src jquery.min.js file at index.php in Chrome I got error 500 jquery.min.map in console. I resolved this problem simply - I disabled extension Wunderlist in Chrome and voila - I never see this error more. Although, No, I found this error again - when Wunderlist have been on again. So, check your extensions and try to disable all of them or some of them or one by one. Good luck!

I created this method to let use it not only on constructors but in methods:

My constructor:

function __construct() {
    $paramsNumber=func_num_args();
    if($paramsNumber==0){
        //do something
    }else{
        $this->overload('__construct',func_get_args());
    }
}

My doSomething method:

public function doSomething() {
    $paramsNumber=func_num_args();
    if($paramsNumber==0){
        //do something
    }else{
        $this->overload('doSomething',func_get_args());
    }
}

Both works with this simple method:

public function overloadMethod($methodName,$params){
    $paramsNumber=sizeof($params);
    //methodName1(), methodName2()...
    $methodNameNumber =$methodName.$paramsNumber;
    if (method_exists($this,$methodNameNumber)) {
        call_user_func_array(array($this,$methodNameNumber),$params);
    }
}

So you can declare

__construct1($arg1), __construct2($arg1,$arg2)...

or

methodName1($arg1), methodName2($arg1,$arg2)...

and so on :)

And when using:

$myObject =  new MyClass($arg1, $arg2,..., $argN);

it will call __constructN, where you defined N args

then $myObject -> doSomething($arg1, $arg2,..., $argM)

it will call doSomethingM, , where you defined M args;

If you do not specifically need the alt text of an image, then you can just target the class/id of the image.

$('img.propImg').each(function(){ 
     enter code here
}

I know it’s not quite answering the question, though I’d spent ages trying to figure this out and this question gave me the solution :). In my case I needed to hide any image tags with a specific src.

$('img.propImg').each(function(){ //for each loop that gets all the images. 
        if($(this).attr('src') == "img/{{images}}") { // if the src matches this
        $(this).css("display", "none") // hide the image.
    }
});

using value get input name

 $('input[value="1"]').attr('name');

using id get input name

 $('input[class="id"]').attr('name');
   $('#id').attr('name');

using class get input name

 $('input[value="classname"]').attr('name');
   $('.classname').attr('name');  //if classname have unique value

   self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage       imageNamed:@"background.png"]];
    [super viewDidLoad];
    }

Perhaps with dataframes one of the most easy and practical solution is:

data = dplyr::mutate(data, rownum=row_number())

The following debug_msg procedure can be called to simply output a debug message to the console:

DELIMITER $$

DROP PROCEDURE IF EXISTS `debug_msg`$$
DROP PROCEDURE IF EXISTS `test_procedure`$$

CREATE PROCEDURE debug_msg(enabled INTEGER, msg VARCHAR(255))
BEGIN
  IF enabled THEN
    select concat('** ', msg) AS '** DEBUG:';
  END IF;
END $$

CREATE PROCEDURE test_procedure(arg1 INTEGER, arg2 INTEGER)
BEGIN
  SET @enabled = TRUE;

  call debug_msg(@enabled, 'my first debug message');
  call debug_msg(@enabled, (select concat_ws('','arg1:', arg1)));
  call debug_msg(TRUE, 'This message always shows up');
  call debug_msg(FALSE, 'This message will never show up');
END $$

DELIMITER ;

Then run the test like this:

CALL test_procedure(1,2)

It will result in the following output:

** DEBUG:
** my first debug message
** DEBUG:
** arg1:1
** DEBUG:
** This message always shows up

Until MySQL implements a bit datatype, if your processing is truly pressed for space and/or time, such as with high volume transactions, create a TINYINT field called bit_flags for all your boolean variables, and mask and shift the boolean bit you desire in your SQL query.

For instance, if your left-most bit represents your bool field, and the 7 rightmost bits represent nothing, then your bit_flags field will equal 128 (binary 10000000). Mask (hide) the seven rightmost bits (using the bitwise operator &), and shift the 8th bit seven spaces to the right, ending up with 00000001. Now the entire number (which, in this case, is 1) is your value.

SELECT (t.bit_flags & 128) >> 7 AS myBool FROM myTable t;

if bit_flags = 128 ==> 1 (true)
if bit_flags = 0 ==> 0 (false)

You can run statements like these as you test

SELECT (128 & 128) >> 7;

SELECT (0 & 128) >> 7;

etc.

Since you have 8 bits, you have potentially 8 boolean variables from one byte. Some future programmer will invariably use the next seven bits, so you must mask. Don’t just shift, or you will create hell for yourself and others in the future. Make sure you have MySQL do your masking and shifting — this will be significantly faster than having the web-scripting language (PHP, ASP, etc.) do it. Also, make sure that you place a comment in the MySQL comment field for your bit_flags field.

You’ll find these sites useful when implementing this method:

• MySQL — Bit Functions and Operators
• Decimal/Binary Conversion Tool

Load testing your API by using just ab is not enough. However, I think it's a great tool to give you a basic idea how your site is performant.

If you want to use the ab command in to test multiple API endpoints, with different data, all at the same time in background, you need to use "nohup" command. It runs any command even when you close the terminal.

I wrote a simple script that automates the whole process, feel free to use it: http://blog.ikvasnica.com/entry/load-test-multiple-api-endpoints-concurrently-use-this-simple-shell-script

If your device is plugged into your computer and your trying to changed send GPS cords Via the Emulator control, it will not work.
This is an EMULATOR control for a reason.
Just set it up to update you on GPS change.

lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);  

    ll = new LocationListener() {        
        public void onLocationChanged(Location location) {  
          // Called when a new location is found by the network location provider.  
            onGPSLocationChanged(location); 
        }

        public void onStatusChanged(String provider, int status, Bundle extras) {       
            bigInfo.setText("Changed "+ status);  
        }

        public void onProviderEnabled(String provider) {
            bigInfo.setText("Enabled "+ provider);
        }

        public void onProviderDisabled(String provider) {
            bigInfo.setText("Disabled "+ provider);
        }
      };

When GPS is updated rewrite the following method to do what you want it to;

public void onGPSLocationChanged(Location location){  
if(location != null){  
    double pLong = location.getLongitude();  
    double pLat = location.getLatitude();  
    textLat.setText(Double.toString(pLat));  
    textLong.setText(Double.toString(pLong));  
    if(autoSave){  
        saveGPS();  
        }
    }
}

A refinement on the answer by JSmyth:

console.logCopy = console.log.bind(console);

console.log = function()
{
    if (arguments.length)
    {
        var timestamp = new Date().toJSON(); // The easiest way I found to get milliseconds in the timestamp
        var args = arguments;
        args[0] = timestamp + ' > ' + arguments[0];
        this.logCopy.apply(this, args);
    }
};

This:

• shows timestamps with milliseconds
• assumes a format string as first parameter to .log

In order to convert string to char

 String str = "abcd";
char arr [] = new char[len]; // len is the length of the array
arr = str.toCharArray();

Yes, the result is always truncated towards zero. It will round towards the smallest absolute value.

-5 / 2 = -2
 5 / 2 =  2

For unsigned and non-negative signed values, this is the same as floor (rounding towards -Infinity).

I use this:

public class ReversedView<E> extends AbstractList<E>{

    public static <E> List<E> of(List<E> list) {
        return new ReversedView<>(list);
    }

    private final List<E> backingList;

    private ReversedView(List<E> backingList){
        this.backingList = backingList;
    }

    @Override
    public E get(int i) {
        return backingList.get(backingList.size()-i-1);
    }

    @Override
    public int size() {
        return backingList.size();
    }

}

like this:

ReversedView.of(backingList) // is a fully-fledged generic (but read-only) list

Probably you can go with this code to take actions as the checkbox is checked or unchecked.

$('#chk').on('click',function(){
    if(this.checked==true){
      alert('yes');
    }else{
      alert('no');
    }
});

Did not like the event-bus approach using $on bindings in the child during create. Why? Subsequent create calls (I'm using vue-router) bind the message handler more than once--leading to multiple responses per message.

The orthodox solution of passing props down from parent to child and putting a property watcher in the child worked a little better. Only problem being that the child can only act on a value transition. Passing the same message multiple times needs some kind of bookkeeping to force a transition so the child can pick up the change.

I've found that if I wrap the message in an array, it will always trigger the child watcher--even if the value remains the same.

Parent:

{
   data: function() {
      msgChild: null,
   },
   methods: {
      mMessageDoIt: function() {
         this.msgChild = ['doIt'];
      }
   }   
   ...
}

Child:

{
   props: ['msgChild'],
   watch: {
      'msgChild': function(arMsg) {
         console.log(arMsg[0]);
      }
   }
}

HTML:

<parent>
   <child v-bind="{ 'msgChild': msgChild }"></child>
</parent>

Select android\gradle\wrapper and open gradle-wrapper.properties

Remove @ResponseBody annotation from your use parameters in method. Like this;

   @Autowired
    ProjectService projectService;

    @RequestMapping(path = "/add", method = RequestMethod.POST)
    public ResponseEntity<Project> createNewProject(Project newProject){
        Project project = projectService.save(newProject);

        return new ResponseEntity<Project>(project,HttpStatus.CREATED);
    }

It's quite simple, use Long.valueOf(String s);

For example:

String s;
long l;

Scanner sc=new Scanner(System.in);
s=sc.next();
l=Long.valueOf(s);
System.out.print(l);

You're done!!!

"N/A" is not an integer. It must throw NumberFormatException if you try to parse it to an integer.

Check before parsing or handle Exception properly.

1. Exception Handling

   try{
       int i = Integer.parseInt(input);
   } catch(NumberFormatException ex){ // handle your exception
       ...
   }
   

or - Integer pattern matching -

String input=...;
String pattern ="-?\\d+";
if(input.matches("-?\\d+")){ // any positive or negetive integer or not!
 ...
}

@TouchBoarder almost had it. Although selecting "Do not launch Activity" results in nothing launching.

In Android Studio under Run/Debug Configuration -> Android Application -> General -> Activity -> select the option "Launch:"

Choose your Activity. This doesn't exactly fix the intended behaviour but rather overrides it correctly.

Please try this:

byte[] decodedString = Base64.decode(person_object.getPhoto(),Base64.NO_WRAP);
InputStream inputStream  = new ByteArrayInputStream(decodedString);
Bitmap bitmap  = BitmapFactory.decodeStream(inputStream);
user_image.setImageBitmap(bitmap);

In my case I needed access to the UILabel that was clicked, so you could do this inside the gesture recognizer.

let label:UILabel = gesture.view as! UILabel

The gesture.view property contains the view of what was clicked, you can simply downcast it to what you know it is.

@IBAction func tapLabel(gesture: UITapGestureRecognizer) {

        let label:UILabel = gesture.view as! UILabel

        guard let text = label.attributedText?.string else {
            return
        }

        print(text)
}

So you could do something like above for the tapLabel function and in viewDidLoad put...

<Label>.addGestureRecognizer(UITapGestureRecognizer(target:self, action: #selector(tapLabel(gesture:))))

Just replace <Label> with your actual label name

I have also faced the same type of problem when I had to parse a CSV file.

The file contains a column address which contains the ',' .

After parsing that CSV file to JSON, I get mismatched mapping of the keys while converting it into a JSON file.

I used Node.js for parsing the file and libraries like baby parse and csvtojson.

Example of file -

address,pincode
foo,baar , 123456

While I was parsing directly without using baby parse in JSON, I was getting:

[{
 address: 'foo',
 pincode: 'baar',
 'field3': '123456'
}]

So I wrote code which removes the comma(,) with any other delimiter with every field:

/*
 csvString(input) = "address, pincode\\nfoo, bar, 123456\\n"
 output = "address, pincode\\nfoo {YOUR DELIMITER} bar, 123455\\n"
*/
const removeComma = function(csvString){
    let delimiter = '|'
    let Baby = require('babyparse')
    let arrRow = Baby.parse(csvString).data;
    /*
      arrRow = [
      [ 'address', 'pincode' ],
      [ 'foo, bar', '123456']
      ]
    */
    return arrRow.map((singleRow, index) => {
        //the data will include
        /*
        singleRow = [ 'address', 'pincode' ]
        */
        return singleRow.map(singleField => {
            //for removing the comma in the feild
            return singleField.split(',').join(delimiter)
        })
    }).reduce((acc, value, key) => {
        acc = acc +(Array.isArray(value) ?
         value.reduce((acc1, val)=> {
            acc1 = acc1+ val + ','
            return acc1
        }, '') : '') + '\n';
        return acc;
    },'')
}

The function returned can be passed into the csvtojson library and thus the result can be used.

const csv = require('csvtojson')

let csvString = "address, pincode\\nfoo, bar, 123456\\n"
let jsonArray = []
modifiedCsvString = removeComma(csvString)
csv()
  .fromString(modifiedCsvString)
  .on('json', json => jsonArray.push(json))
  .on('end', () => {
    /* do any thing with the json Array */
  })

Now you can get the output like:

[{
  address: 'foo, bar',
  pincode: 123456
}]

You need to implement the equals() method in your MyClass.

The reason that == didn't work is this is checking that they refer to the same instance. Since you did new for each, each one is a different instance.

The reason that equals() didn't work is because you didn't implement it yourself yet. I believe it's default behavior is the same thing as ==.

Note that you should also implement hashcode() if you're going to implement equals() because a lot of java.util Collections expect that.

Here's a simple scraper I created in c# to get streaming quote data printed out to a console. It should be easily converted to java. Based on the following post:

git branch --set-upstream-to=origin/main

Your submodule history is safely preserved in the submodule git anyway.

So, why not just delete the submodule and add it again?

Otherwise, did you try manually editing the HEAD or the refs/master/head within the submodule .git

Drag & Drop

To install apk in avd, just manually drag and drop the apk file in the opened emulated device

The same if you want to copy a file to the sd card

Many ways to do it. I guess the key is to do it in the most efficient way possible (without looping the string). I would do it as a char array which can be reversed easily (using C#).

string mystring = "abracadabra";

char[] str = mystring.ToCharArray();
Array.Reverse(str);
string revstring = new string(str);

if (mystring.equals(revstring))
{
    Console.WriteLine("String is a Palindrome");
}

Default access modifier - If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes).

Why setContentView() in Android Had Been So Popular Till Now?

setContentView(int layoutid) - method of activity class. It shows layout on screen.

R.layout.main - is an integer number implemented in nested layout class of R.java class file.

At the run time device will pick up their layout based on the id given in setcontentview() method.

For R version 4.0.2 on Ubuntu 18.0.4, I had to install the the libgit2-dev package:

sudo apt-get install libgit2-dev

After that, worked like a charm.

I experienced this issue and I preferred to free up the port .80 and my XAMPP/Apache restarted again. This is how I made the port .80 free. First: -Open a command prompt and type this :

netstat -aon | findstr :80

You'll get this display:

Then type this command:

tasklist /fi "pid eq 4"

You'll get the name of the process using the is displayed. Now, press: Win+R services.msc in the invite, then press Ok. Now you can start stopping all services which can use the port .80.

Find some of them here: W3SVC,WAS,SSRS,PeerDistSvc,NcbService.

If the previously mentioned higher z-indexing in parent nodes wont suit your needs, you can create alternative solution and target it to problematic browsers either by IE conditional comments or using the (more idealistic) feature detection provided by Modernizr.

Quick (and obviously working) test for Modernizr:

Modernizr.addTest('compliantzindex', function(){
    var test  = document.createElement('div'),
        fake = false,
        root = document.body || (function () {
            fake = true;
            return document.documentElement.appendChild(document.createElement('body'));
        }());

    root.appendChild(test);
    test.style.position = 'relative';
    var ret = (test.style.zIndex !== 0);
    root.removeChild(test);

    if (fake) {
        document.documentElement.removeChild(root);
    }

    return ret;
});

If you're hoping to use background-image: url(...);, I don't think you can. However, if you want to play with layering, you can do something like this:

<img class="bg" src="..." />

And then some CSS:

.bg
{
  width: 100%;
  z-index: 0;
}

You can now layer content above the stretched image by playing with z-indexes and such. One quick note, the image can't be contained in any other elements for the width: 100%; to apply to the whole page.

Here's a quick demo if you can't rely on background-size: http://jsfiddle.net/bB3Uc/

I don't know if this is what you're looking for, but you can export the results to Excel like this:

In the results pane, click the top-left cell to highlight all the records, and then right-click the top-left cell and click "Save Results As". One of the export options is CSV.

You might give this a shot too:

INSERT INTO OPENROWSET 
   ('Microsoft.Jet.OLEDB.4.0', 
   'Excel 8.0;Database=c:\Test.xls;','SELECT productid, price FROM dbo.product')

Lastly, you can look into using SSIS (replaced DTS) for data exports. Here is a link to a tutorial:

http://www.accelebrate.com/sql_training/ssis_2008_tutorial.htm

== Update #1 ==

To save the result as CSV file with column headers, one can follow the steps shown below:

1. Go to Tools->Options
2. Query Results->SQL Server->Results to Grid
3. Check “Include column headers when copying or saving results”
4. Click OK.
5. Note that the new settings won’t affect any existing Query tabs — you’ll need to open new ones and/or restart SSMS.

[[UIDevice currentDevice] systemVersion];

or check the version like

You can get the below Macros from here.

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(IOS_VERSION_3_2_0))      
{

        UIImageView *background = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cs_lines_back.png"]] autorelease];
        theTableView.backgroundView = background;

}

Hope this helps

You create handler in background thread this way

private void createHandler() {
        Thread thread = new Thread() {
          public void run() {
               Looper.prepare();

               final Handler handler = new Handler();
               handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                       // Do Work
                        handler.removeCallbacks(this);
                        Looper.myLooper().quit();
                   }
                }, 2000);

                Looper.loop();
            }
        };
        thread.start();
    }

To run a URL simply use command below easy yess CPanel 100%

/usr/bin/php -q /home/CpanelUsername/public_html/RootFolder/cronjob/fetch.php

I hope this help.

I recommend looking at modern databases like NoSQL and also I agree with user1252434's post. For instance I am storing a few < 500kb PNGs as base64 on my Mongo db with binary set to true with no performance hit at all. Mongo can be used to store large files like 10MB videos and that can offer huge time saving advantages in metadata searches for those videos, see storing large objects and files in mongodb.

Following on from LES2's answer, you can eliminate some repetition in the efficient version, by calling the overloaded function:

public static <T> T coalesce(T a, T b) {
    return a != null ? a : b;
}
public static <T> T coalesce(T a, T b, T c) {
    return a != null ? a : coalesce(b,c);
}
public static <T> T coalesce(T a, T b, T c, T d) {
    return a != null ? a : coalesce(b,c,d);
}
public static <T> T coalesce(T a, T b, T c, T d, T e) {
    return a != null ? a : coalesce(b,c,d,e);
}

Static method is inherited in subclass but it is not polymorphism. When you writing the implementation of static method, the parent's class method is over hidden, not overridden. Think, if it is not inherited then how you can be able to access without classname.staticMethodname();?

Another alternative to use the exact json within javascript. As it is Javascript Object Notation you can just create your object directly with the json notation. If you store this in a .js file you can use the object in your application. This was a useful option for me when I had some static json data that I wanted to cache in a file separately from the rest of my app.

    //Just hard code json directly within JS
    //here I create an object CLC that represents the json!
    $scope.CLC = {
        "ContentLayouts": [
            {
                "ContentLayoutID": 1,
                "ContentLayoutTitle": "Right",
                "ContentLayoutImageUrl": "/Wasabi/Common/gfx/layout/right.png",
                "ContentLayoutIndex": 0,
                "IsDefault": true
            },
            {
                "ContentLayoutID": 2,
                "ContentLayoutTitle": "Bottom",
                "ContentLayoutImageUrl": "/Wasabi/Common/gfx/layout/bottom.png",
                "ContentLayoutIndex": 1,
                "IsDefault": false
            },
            {
                "ContentLayoutID": 3,
                "ContentLayoutTitle": "Top",
                "ContentLayoutImageUrl": "/Wasabi/Common/gfx/layout/top.png",
                "ContentLayoutIndex": 2,
                "IsDefault": false
            }
        ]
    };

Look at the types of those properties:

In [1]: import datetime

In [2]: d = datetime.date.today()

In [3]: type(d.month)
Out[3]: <type 'int'>

In [4]: type(d.day)
Out[4]: <type 'int'>

Both are integers. So there is no automatic way to do what you want. So in the narrow sense, the answer to your question is no.

If you want leading zeroes, you'll have to format them one way or another. For that you have several options:

In [5]: '{:02d}'.format(d.month)
Out[5]: '03'

In [6]: '%02d' % d.month
Out[6]: '03'

In [7]: d.strftime('%m')
Out[7]: '03'

In [8]: f'{d.month:02d}'
Out[8]: '03'

This solution worked for me:

First install django-phone-field

command: pip install django-phone-field

then on models.py

from phone_field import PhoneField
...

class Client(models.Model):
    ...
    phone_number = PhoneField(blank=True, help_text='Contact phone number')

and on settings.py

INSTALLED_APPS = [...,
                  'phone_field'
]

It looks like this in the end

With gradle, I replaced this line at build.gradle.kts file inside dependencies block

providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")

with this

compile("org.springframework.boot:spring-boot-starter-web")

and works fine.

The Node.js package is available in the LTS release and the current release. It’s your choice to select which version you want to install on the system as per your requirements.

Use Current Release: At the last update of this tutorial, Node.js 13 is the current Node.js release available.

sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_13.x | sudo -E bash -

Use LTS Release: At the last update of this tutorial, Node.js 12.x is the LTS release available.

sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

You can successfully add Node.js PPA to the Ubuntu system. Now execute the below command to install Node.js on and Ubuntu using apt-get. This will also install NPM with Node.js. This command also installs many other dependent packages on your system.

sudo apt-get install nodejs

After installing Node.js, verify and check the installed version. You can find more details about the current version on the Node.js official website.

node -v

v13.0.1

Also, check the npm version:

npm -v

6.12.0

int day = (int)DateTime.Now.DayOfWeek;

First day of the week: Sunday (with a value of zero)

I think that the idea of setting the Auto Return values as described above by Kevin is a bit strange!

Say, for example, that you have a number of websites that use the same PayPal account to handle your payments, or say that you have a number of sections in one website that perform different purchasing tasks, and require different return-addresses when the payment is completed. If I put a button on my page as described above in the 'Sample form using PHP for direct payments' section, you can see that there is a line there:

input type="hidden" name="return" value="https://www.yoursite.com/checkout_complete.php"

where you set the individual return value. Why does it have to be set generally, in the profile section as well?!?!

Also, because you can only set one value in the Profile Section, it means (AFAIK) that you cannot use the Auto Return on a site with multiple actions.

Comments please??

If you just want to iterate over these sets of elements rather than construct a separate data structure, consider using iterators to construct a generator expression:

def shift(l,n):
    return itertools.islice(itertools.cycle(l),n,n+len(l))

>>> list(shift([1,2,3],1))
[2, 3, 1]

You want something like this:

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
import java.io.IOException;

public class StringXORer {

    public String encode(String s, String key) {
        return base64Encode(xorWithKey(s.getBytes(), key.getBytes()));
    }

    public String decode(String s, String key) {
        return new String(xorWithKey(base64Decode(s), key.getBytes()));
    }

    private byte[] xorWithKey(byte[] a, byte[] key) {
        byte[] out = new byte[a.length];
        for (int i = 0; i < a.length; i++) {
            out[i] = (byte) (a[i] ^ key[i%key.length]);
        }
        return out;
    }

    private byte[] base64Decode(String s) {
        try {
            BASE64Decoder d = new BASE64Decoder();
            return d.decodeBuffer(s);
        } catch (IOException e) {throw new RuntimeException(e);}
    }

    private String base64Encode(byte[] bytes) {
        BASE64Encoder enc = new BASE64Encoder();
        return enc.encode(bytes).replaceAll("\\s", "");

    }
}

The base64 encoding is done because xor'ing the bytes of a string may not give valid bytes back for a string.

#include <stdio.h>
#include <string.h>

int main(void){
    char word[17], outword[33];//17:16+1, 33:16*2+1
    int i, len;

    printf("Intro word:");
    fgets(word, sizeof(word), stdin);
    len = strlen(word);
    if(word[len-1]=='\n')
        word[--len] = '\0';

    for(i = 0; i<len; i++){
        sprintf(outword+i*2, "%02X", word[i]);
    }
    printf("%s\n", outword);
    return 0;
}

You want to create a class that implements ResponseErrorHandler and then use an instance of it to set the error handling of your rest template:

public class MyErrorHandler implements ResponseErrorHandler {
  @Override
  public void handleError(ClientHttpResponse response) throws IOException {
    // your error handling here
  }

  @Override
  public boolean hasError(ClientHttpResponse response) throws IOException {
     ...
  }
}

[...]

public static void main(String args[]) {
  RestTemplate restTemplate = new RestTemplate();
  restTemplate.setErrorHandler(new MyErrorHandler());
}

Also, Spring has the class DefaultResponseErrorHandler, which you can extend instead of implementing the interface, in case you only want to override the handleError method.

public class MyErrorHandler extends DefaultResponseErrorHandler {
  @Override
  public void handleError(ClientHttpResponse response) throws IOException {
    // your error handling here
  }
}

Take a look at its source code to have an idea of how Spring handles HTTP errors.

The above would very well work, but it seems you have missed the jQuery typecast for the dropdown text. Other than that it would be advisable to use .val() to set text for an input text type element. With these changes the code would look like the following:

    $('#txtEntry2').val($('#ddlCodes option:selected').text());

This is the problem:

global str

str = str(mar)

You are redefining what str() means. str is the built-in Python name of the string type, and you don't want to change it.

Use a different name for the local variable, and remove the global statement.

So easy:

git diff --name-only

Go forth and diff!

Here is a more concise version of the accepted answer which avoids repeating the NoteProperty identifiers and the [pscustomobject]-cast:

$myItems =  ("Joe",32,"something about him"), ("Sue",29,"something about her")
            | ForEach-Object {[pscustomobject]@{name = $_[0]; age = $_[1]; info = $_[2]}}

Result:

> $myItems

name           age         info
----           ---         ----
Joe            32          something about him
Sue            29          something about her

This answers the 'best random' request:

Adi's answer¹ from Security.StackExchange has a solution for this:

Make sure you have OpenSSL support, and you'll never go wrong with this one-liner

API keys are just one way of authenticating users of web services.

npm install -g npm@4

This will install the latest version on the major release 4, no no need to specify version number. Replace 4 with whatever major release you want.

The simplest method is just to use the + operator, which returns the concatenation of the lists:

concat = first_list + second_list

One disadvantage of this method is that twice the memory is now being used . For very large lists, depending on how you're going to use it once it's created, itertools.chain might be your best bet:

>>> import itertools
>>> a = [1, 2, 3]
>>> b = [4, 5, 6]
>>> c = itertools.chain(a, b)

This creates a generator for the items in the combined list, which has the advantage that no new list needs to be created, but you can still use c as though it were the concatenation of the two lists:

>>> for i in c:
...     print i
1
2
3
4
5
6

If your lists are large and efficiency is a concern then this and other methods from the itertools module are very handy to know.

Note that this example uses up the items in c, so you'd need to reinitialise it before you can reuse it. Of course you can just use list(c) to create the full list, but that will create a new list in memory.

If you want to print decimal variables:

wchar_t text_buffer[20] = { 0 }; //temporary buffer
swprintf(text_buffer, _countof(text_buffer), L"%d", your.variable); // convert
OutputDebugString(text_buffer); // print

Use FormulaR1C1:

Cells((1,3),(10,3)).FormulaR1C1 = "=RC[-2]+RC[-1]"

Unlike Formula, FormulaR1C1 has relative referencing.

From the documentation I found this

JObject o = new JObject(
   new JProperty("Name", "John Smith"),
   new JProperty("BirthDate", new DateTime(1983, 3, 20))
);

JsonSerializer serializer = new JsonSerializer();
Person p = (Person)serializer.Deserialize(new JTokenReader(o), typeof(Person));

Console.WriteLine(p.Name);

The class definition for Person should be compatible to the following:

class Person {
    public string Name { get; internal set; }
    public DateTime BirthDate { get; internal set; }
}

Edit

If you are using a recent version of JSON.net and don't need custom serialization, please see TienDo's answer above (or below if you upvote me :P ), which is more concise.

you can use background-origin:padding-box; and then add some padding where you want, for example: #logo {background-image: url(your/image.jpg); background-origin:padding-box; padding-left: 15%;} This way you attach the image to the div padding box that contains it so you can position it wherever you want.

Or you can use this javascript

$(function () {
    $("#projectKey").change(function () {
        alert($('#projectKey option:selected').text());
    });
});

I needed something to call scripts with named parameters. We have a policy of not using ordinal positioning of parameters and requiring the parameter name.

My approach is similar to the ones above but gets the content of the script file that you want to call and sends a parameter block containing the parameters and values.

One of the advantages of this is that you can optionally choose which parameters to send to the script file allowing for non-mandatory parameters with defaults.

Assuming there is a script called "MyScript.ps1" in the temporary path that has the following parameter block:

[CmdletBinding(PositionalBinding = $False)]
param
(
    [Parameter(Mandatory = $True)] [String] $MyNamedParameter1,
    [Parameter(Mandatory = $True)] [String] $MyNamedParameter2,
    [Parameter(Mandatory = $False)] [String] $MyNamedParameter3 = "some default value"
)

This is how I would call this script from another script:

$params = @{
    MyNamedParameter1 = $SomeValue
    MyNamedParameter2 = $SomeOtherValue
}

If ($SomeCondition)
{
    $params['MyNamedParameter3'] = $YetAnotherValue
}

$pathToScript = Join-Path -Path $env:Temp -ChildPath MyScript.ps1

$sb = [scriptblock]::create(".{$(Get-Content -Path $pathToScript -Raw)} $(&{
        $args
} @params)")
Invoke-Command -ScriptBlock $sb

I have used this in lots of scenarios and it works really well. One thing that you occasionally need to do is put quotes around the parameter value assignment block. This is always the case when there are spaces in the value.

e.g. This param block is used to call a script that copies various modules into the standard location used by PowerShell C:\Program Files\WindowsPowerShell\Modules which contains a space character.

$params = @{
        SourcePath      = "$WorkingDirectory\Modules"
        DestinationPath = "'$(Join-Path -Path $([System.Environment]::GetFolderPath('ProgramFiles')) -ChildPath 'WindowsPowershell\Modules')'"
    }

Hope this helps!

JQuery:

$(function () {
      $('.SendEmail').click(function (event) {
        var email = '[email protected]';
        var subject = 'Test';
        var emailBody = 'Hi Sample,';
        var attach = 'path';
        document.location = "mailto:"+email+"?subject="+subject+"&body="+emailBody+

I found that focus does not work when trying to get a focus on a text element (such as a notice div), but does work when focusing on input fields.

You can use open(name, 'a')

However, when you enter filename, use inverted commas on both sides, otherwise ".txt"cannot be added to filename

As gratitude to the timely help I got from here - a minor update to above.

$query = "UPDATE `db`.`table` SET `fieldname`=  str_to_date(  fieldname, '%d/%m/%Y')";

This feature is known as generics. http://msdn.microsoft.com/en-us/library/512aeb7t(v=vs.100).aspx

An example of this is to make a collection of items of a specific type.

class MyArray<T>
{
    T[] array = new T[10];

    public T GetItem(int index)
    {
        return array[index];
    }
}

In your code, you could then do something like this:

MyArray<int> = new MyArray<int>();

In this case, T[] array would work like int[] array, and public T GetItem would work like public int GetItem.

Actually you want 3.46 from 3.4679 . This is only representation of characters.So there is nothing to do with math function.Math function is not intended to do this work. Simply use the following code.

Dim str1 As String
str1=""
str1 ="3.4679" 
  Dim substring As String = str1.Substring(0, 3)

    ' Write the results to the screen.
    Console.WriteLine("Substring: {0}", substring)

Or 
    Please use the following code.
Public function result(ByVal x1 As Double) As String 
  Dim i as  Int32
  i=0
  Dim y as String
  y = ""
  For Each ch as Char In x1.ToString
    If i>3 then
     Exit For
    Else
    y + y +ch
    End if
    i=i+1
  Next
  return y
End Function

The above code can be modified for any numbers Put the following code in a button click event

Dim str As String 
str= result(3.4679)
 MsgBox("The number is " & str)

In Doctrine 2.x you can't pass multiple order by using doctrine 'orderBy' or 'addOrderBy' as above examples. Because, it automatically adds the 'ASC' at the end of the last column name when you left the second parameter blank, such as in the 'orderBy' function.

For an example ->orderBy('a.fist_name ASC, a.last_name ASC') will output SQL something like this 'ORDER BY first_name ASC, last_name ASC ASC'. So this is SQL syntax error. Simply because default of the orderBy or addOrderBy is 'ASC'.

To add multiple order by's you need to use 'add' function. And it will be like this.

->add('orderBy','first_name ASC, last_name ASC'). This will give you the correctly formatted SQL.

More info on add() function. https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/query-builder.html#low-level-api

Hope this helps. Cheers!

I had same issue with VMWare 12.5.2 and OS: Mac OS Sierra.
These are few steps to solve this issue:(which worked for me.)

1. Open VMWare.
2. select your OS. (Mine is MacOS Sierra)
3. Then In left hand side, Select option "Edit virtual machine settings"
4. There will be one popup of setting. In that you need to select "Hardware" Tab.
5. In that, there is option "USB Controller". Select that. You will find option right hand side.
6. In that, Set USB compatibility as "USB 2.0" and check all 3 options as selected. options must be as following: i) Automatically connect new USB devices, ii) Show all USB input devices, iii) Share Bluetooth devices with the virtual machine
7. Press OK.

There you go. It will work. Now you can power on your virtual machine.And try to connect your device with proper USB cable. Sometimes there can be issue with USB cable which are not authorized. Still if you have doubt, you can ask me here.

This can be achieved without body-parser dependency as well, listen to request:data and request:end and return the response on end of request, refer below code sample. ref:https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/#request-body

var express = require('express');
var app = express.createServer(express.logger());

app.post('/', function(request, response) {

    // push the data to body
    var body = [];
    request.on('data', (chunk) => {
      body.push(chunk);
    }).on('end', () => {
      // on end of data, perform necessary action
      body = Buffer.concat(body).toString();
      response.write(request.body.user);
      response.end();
    });
});

All of the following applies to InnoDB.

I feel knowing the speeds of the 3 different methods is important.

There are 3 methods:

1. INSERT: INSERT with ON DUPLICATE KEY UPDATE
2. TRANSACTION: Where you do an update for each record within a transaction
3. CASE: In which you a case/when for each different record within an UPDATE

I just tested this, and the INSERT method was 6.7x faster for me than the TRANSACTION method. I tried on a set of both 3,000 and 30,000 rows.

The TRANSACTION method still has to run each individually query, which takes time, though it batches the results in memory, or something, while executing. The TRANSACTION method is also pretty expensive in both replication and query logs.

Even worse, the CASE method was 41.1x slower than the INSERT method w/ 30,000 records (6.1x slower than TRANSACTION). And 75x slower in MyISAM. INSERT and CASE methods broke even at ~1,000 records. Even at 100 records, the CASE method is BARELY faster.

So in general, I feel the INSERT method is both best and easiest to use. The queries are smaller and easier to read and only take up 1 query of action. This applies to both InnoDB and MyISAM.

Bonus stuff:

The solution for the INSERT non-default-field problem is to temporarily turn off the relevant SQL modes: SET SESSION sql_mode=REPLACE(REPLACE(@@SESSION.sql_mode,"STRICT_TRANS_TABLES",""),"STRICT_ALL_TABLES",""). Make sure to save the sql_mode first if you plan on reverting it.

As for other comments I've seen that say the auto_increment goes up using the INSERT method, this does seem to be the case in InnoDB, but not MyISAM.

Code to run the tests is as follows. It also outputs .SQL files to remove php interpreter overhead

<?php
//Variables
$NumRows=30000;

//These 2 functions need to be filled in
function InitSQL()
{
