Programs & Examples On #Application integration

I do not agree with the rules given in the original post. Here are my rules:

1) You use structs for performance when stored in arrays. (see also When are structs the answer?)

2) You need them in code passing structured data to/from C/C++

3) Do not use structs unless you need them:

• They behave different from "normal objects" (reference types) under assignment and when passing as arguments, which can lead to unexpected behavior; this is particularly dangerous if the person looking at the code does not know they are dealing with a struct.
• They cannot be inherited.
• Passing structs as arguments is more expensive than classes.

Another option might be to avoid WCF all-together and just use a .NET HttpHandler. The HttpHandler can grab the query-string variables from your GET and just write back a response to the Java code.

It's close! Try this:

for (var prop in result) {
    if (result.hasOwnProperty(prop)) {
        alert(result[prop]);
    }
}

Update:

If your result is truly is an array of one object, then you might have to do this:

for (var prop in result[0]) {
    if (result[0].hasOwnProperty(prop)) {
        alert(result[0][prop]);
    }
}

Or if you want to loop through each result in the array if there are more, try:

for (var i = 0; i < results.length; i++) {
    for (var prop in result[i]) {
        if (result[i].hasOwnProperty(prop)) {
            alert(result[i][prop]);
        }
    }
}

Swift 3+ one liner to sum properties of objects

var totalSum = scaleData.map({$0.points}).reduce(0, +)

Where points is the property in my custom object scaleData that I am trying to reduce

const date = moment(YOUR_DATE)
return (moment().diff(date, 'days') >= 2) ? date.fromNow() : date.calendar().split(' ')[0]

request.getSession() or request.getSession(true) both will return a current session only . if current session will not exist then it will create a new session.

From Unix.SE: A simple command-line utility called gpustat now exists: https://github.com/wookayin/gpustat.

It is free software (MIT license) and is packaged in pypi. It is a wrapper of nvidia-smi.

Date.prototype.addDays = function(days) {
    var date = new Date(this.valueOf());
    date.setDate(date.getDate() + days);
    return date;
}

function getDates(startDate, stopDate) {
    var dateArray = new Array();
    var currentDate = startDate;
    while (currentDate <= stopDate) {
        dateArray.push(new Date (currentDate));
        currentDate = currentDate.addDays(1);
    }
    return dateArray;
}

Here is a functional demo http://jsfiddle.net/jfhartsock/cM3ZU/

>>> 'QH QD JC KD JS'.split()
['QH', 'QD', 'JC', 'KD', 'JS']

split:

Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). If maxsplit is not specified, then there is no limit on the number of splits (all possible splits are made).

If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings (for example, '1,,2'.split(',') returns ['1', '', '2']). The sep argument may consist of multiple characters (for example, '1<>2<>3'.split('<>') returns ['1', '2', '3']). Splitting an empty string with a specified separator returns [''].

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns [].

For example, ' 1 2 3 '.split() returns ['1', '2', '3'], and ' 1 2 3 '.split(None, 1) returns ['1', '2 3 '].

I think it bears repeating: html_safe does not HTML-escape your string. In fact, it will prevent your string from being escaped.

<%= "<script>alert('Hello!')</script>" %>

will put:

<script>alert('Hello!')</script>

into your HTML source (yay, so safe!), while:

<%= "<script>alert('Hello!')</script>".html_safe %>

will pop up the alert dialog (are you sure that's what you want?). So you probably don't want to call html_safe on any user-entered strings.

How about the following, where y is the name of your matrix and you are looking for the maximum in the entire matrix:

row(y)[y==max(y)]

if you want to extract the row:

y[row(y)[y==max(y)],] # this returns unsorted rows.

To return sorted rows use:

y[sort(row(y)[y==max(y)]),]

The advantage of this approach is that you can change the conditional inside to anything you need. Also, using col(y) and location of the hanging comma you can also extract columns.

y[,col(y)[y==max(y)]]

To find just the row for the max in a particular column, say column 2 you could use:

seq(along=y[,2])[y[,2]==max(y[,2])]

again the conditional is flexible to look for different requirements.

See Phil Spector's excellent "An introduction to S and S-Plus" Chapter 5 for additional ideas.

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

If you want to run angular app ported from another machine without ng command then edit package.json as follows

"scripts": {
    "ng": "ng",
    "start": "node node_modules/.bin/ng serve",
    "build": "node node_modules/.bin/ng build",
    "test": "node node_modules/.bin/ng test",
    "lint": "node node_modules/.bin/ng lint",
    "e2e": "node node_modules/.bin/ng e2e"
  }

Finally run usual npm start command to start build server.

For older versions of Hibernate (<5.2):

Assuming the class name is Book:

return (Number) session.createCriteria("Book")
                  .setProjection(Projections.rowCount())
                  .uniqueResult();

It is at least a Number, most likely a Long.

private int user_movie_matrix[][];Th. should be `private int user_movie_matrix[][];.

private int user_movie_matrix[][]; should be private static int user_movie_matrix[][];

cfiltering(numberOfUsers, numberOfMovies); should be new cfiltering(numberOfUsers, numberOfMovies);

Whether or not the code works as intended after these changes is beyond the scope of this answer; there were several syntax/scoping errors.

if you want to use it inside a 'for' to copy the last generated files for a every-day bacakup...

j=0  
var="`find /backup/path/ -name 'something*' -type f -mtime -1`"  
#we have in $var some files with last day change date

for i in $var  
  do  
  j=$(( $j + 1 ))  
  dirname="`dirname $i`"  
  filename="`basename $i`"  
  /usr/bin/ftp -in >> /tmp/ftp.good 2>> /tmp/ftp.bad << EOF  
    open 123.456.789.012  
    user user_name passwd  
    bin  
    lcd $dirname  
    put $filename  
    quit  
  EOF      #end of ftp

To select content use Alt + Shift + Up arrow

To select content up to the next wrapping block press this shortcut again

To go back one step press Alt + Shift + Down arrow. This is also a useful shortcut when you need to select content in a complex expression and do not want to miss something.

Responsive with CSS You can make the Iframe responsive with the following CSS codes.

.map {
    position: relative;
    padding-bottom: 26.25%;
    padding-top: 30px;
    height: 0;
    overflow: hidden;
}

.map iframe,
.map object,
.map embed {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

Responsive with JavaScript

This possible through window.resize event and you can apply this on google map like google.maps.event.addDomListener(window, 'resize', initialize);

Consider the following example:

function initialize() {
    var mapOptions = {
           zoom: 9,
           center: new google.maps.LatLng(28.9285745, 77.09149350000007),  
           mapTypeId: google.maps.MapTypeId.TERRAIN
    };
    
    var map = new google.maps.Map(document.getElementById('location-canvas'), mapOptions);
    var marker = new google.maps.Marker({
           map: map,
           draggable: false,
           position: new google.maps.LatLng(28.9285745, 77.09149350000007)
     });
}
google.maps.event.addDomListener(window, 'resize', initialize);

Only use Redim statement

 Dim aFirstArray() As Variant

Redim aFirstArray(nRows,nColumns)

You may try this example:

<form>_x000D_
  <h1>Hello! I'm duke! What's you name?</h1>_x000D_
  <input type="text" name="user">_x000D_
  <br>_x000D_
  <br>_x000D_
  <input type="submit" value="submit">&nbsp;&nbsp;&nbsp;&nbsp;_x000D_
  <input type="reset">_x000D_
</form>_x000D_
<h1>Hello ${param.user}</h1> _x000D_

If you want to download gradle with source and docs, the default distribution url configured in gradle-wrapper.properites will not satisfy your need.It is https://services.gradle.org/distributions/gradle-2.10-bin.zip, not https://services.gradle.org/distributions/gradle-2.10-all.zip.This full url is suggested by IDE such as Android Studio.If you want to download the full gradle,You can configure the wrapper task like this:

task wrapper(type: Wrapper) {
    gradleVersion = '2.13'
    distributionUrl = distributionUrl.replace("bin", "all")
}

Have you tried simply 'reboot' with adb?

  adb reboot

Also you can run complete shell scripts (e.g. to reboot your emulator) via adb:

 adb shell <command>

The official docs can be found here.

It is possible to upack without node installed using the following 7-Zip plugin:
http://www.tc4shell.com/en/7zip/asar/

Thanks @MayaPosch for mentioning that in this comment.

You're nearly there, just take out the EXECUTE:

DECLARE
  procId NUMBER;

BEGIN
  PKG1.INIT(1143824, 0, procId);
  DBMS_OUTPUT.PUT_LINE(procId);
END;

Better to use text box for calling/displaying date and while saving use DateTimePicker. Make visible property true or false as per requirement.

For eg : During form load make Load date in Textbox and make DTPIcker invisible and while adding vice versa

You could easily replace the forward slashes / with something like an underscore _ such as Wikipedia uses for spaces. Replacing special characters with underscores, etc., is common practice.

This error message appeared for me when I tried to debug two solutions at the same time as I wanted to visually compare the differences. Unchecking the Enable JavaScript Debugging for ASP.NET (Chrome and IE) option worked, but I am still confused why I could not debug more than one solution at a time. Since it is a known issue, maybe this will be address in an update from Visual Studio. Here is to hoping ....

If the model specified for the drop down does not exist then angular will generate an empty options element. So you will have to explicitly specify the model on the select like this:

<select ng-model="regions[index]" ng-options="....">

Refer to the following as it has been answered before:

Why does AngularJS include an empty option in select? and this fiddle

Update: Try this instead:

<select ng-model="regions[index].code" ng-options="i.code as i.name for i in regions">
</select>

or

<select ng-model="regions[2]" ng-options="r.name for r in regions">
</select>

Note that there is no empty options element in the select.

By referring this(http://www.excelforum.com/excel-programming-vba-macros/867665-application-cutcopymode-false.html) link the answer is as below:

Application.CutCopyMode=False is seen in macro recorder-generated code when you do a copy/cut cells and paste . The macro recorder does the copy/cut and paste in separate statements and uses the clipboard as an intermediate buffer. I think Application.CutCopyMode = False clears the clipboard. Without that line you will get the warning 'There is a large amount of information on the Clipboard....' when you close the workbook with a large amount of data on the clipboard.

With optimised VBA code you can usually do the copy/cut and paste operations in one statement, so the clipboard isn't used and Application.CutCopyMode = False isn't needed and you won't get the warning.

I was using this two lines in the url and the template from the admin what i was changing to my need

url(r'^change-password/$', 'django.contrib.auth.views.password_change', {
    'template_name': 'password_change_form.html'}, name="password-change"),
url(r'^change-password-done/$', 'django.contrib.auth.views.password_change_done', {
    'template_name': 'password_change_done.html'
    }, name="password-change-done")

Here you can add to sDom element to your code, top search bar is hidden.

$(document).ready(function() {
    $('#example').dataTable( {
"sDom": '<"top">rt<"bottom"flp><"clear">'
 } );
} );

This is a simple code that uses the System.in.read() function. This code just writes out whatever was typed. You can get rid of the while loop if you just want to take input once, and you could store answers in a character array if you so choose.

package main;

import java.io.IOException;

public class Root 
{   
    public static void main(String[] args)
    {
        new Root();
    }

    public Root()
    {
        while(true)
        {
            try
            {
                for(int y = 0; y < System.in.available(); ++y)
                { 
                    System.out.print((char)System.in.read()); 
                }
            }
            catch(IOException ex)
            {
                ex.printStackTrace(System.out);
                break;
            }
        }
    }   
}    

Well first of all I think rolling out your own solution for this all you need is urllib2 or httplib2 . Anyways in case you do require a generic REST client check this out .

https://github.com/scastillo/siesta

However i think the feature set of the library will not work for most web services because they shall probably using oauth etc .. . Also I don't like the fact that it is written over httplib which is a pain as compared to httplib2 still should work for you if you don't have to handle a lot of redirections etc ..

Use the $elemMatch operator: according to the documentation

The $elemMatch operator matches documents that contain an array field with at least one element that matches all the specified query criteria.

$elemMatches makes sure that the value is an array and that it is not empty. So the query would be something like

ME.find({ pictures: { $elemMatch: {$exists: true }}})

PS A variant of this code is found in MongoDB University's M121 course.

You can change the index as explained already using set_index. You don't need to manually swap rows with columns, there is a transpose (data.T) method in pandas that does it for you:

> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
                    ['ABERFELDIE', 534000, 600000]],
                    columns=['Locality', 2005, 2006])

> newdf = df.set_index('Locality').T
> newdf

Locality    ABBOTSFORD  ABERFELDIE
2005        427000      534000
2006        448000      600000

then you can fetch the dataframe column values and transform them to a list:

> newdf['ABBOTSFORD'].values.tolist()

[427000, 448000]

In your res/layout/my_image_layout.xml

<LinearLayout ...>
    <ImageView
        android:id="@+id/row_0_col_7"
      ...>
    </ImageView>
</LinearLayout>

To grab that ImageView by its @+id value, inside your java code do this:

String row = "0";
String column= "7";
String tileID = "row_" + (row) + "_col_" + (column);
ImageView image = (ImageView) activity.findViewById(activity.getResources()
                .getIdentifier(tileID, "id", activity.getPackageName()));

/*Bottom code changes that ImageView to a different image. "blank" (R.mipmap.blank) is the name of an image I have in my drawable folder. */
image.setImageResource(R.mipmap.blank);  

Use this line to make this work while using the modal:true option.

open: function (type, data) { 
    $('.ui-widget-overlay').appendTo("form"); $(this).parent().appendTo("form"); 
  },

You can create functions in react components. It is actually regular ES6 class which inherits from React.Component. Just be careful and bind it to the correct context in onClick event:

export default class Archive extends React.Component { 

    saySomething(something) {
        console.log(something);
    }

    handleClick(e) {
        this.saySomething("element clicked");
    }

    componentDidMount() {
        this.saySomething("component did mount");
    }

    render() {
        return <button onClick={this.handleClick.bind(this)} value="Click me" />;
    }
}

You should use a Set. A Set is a Collection that contains no duplicates.

If you have a List that contains duplicates, you can get the unique entries like this:

List<String> gasList = // create list with duplicates...
Set<String> uniqueGas = new HashSet<String>(gasList);
System.out.println("Unique gas count: " + uniqueGas.size());

NOTE: This HashSet constructor identifies duplicates by invoking the elements' equals() methods.

If you are trying to return back the ID within the scope, using the SCOPE_IDENTITY() would be a better approach. I would not advice to use @@IDENTITY, as this can return any ID.

CREATE PROC [dbo].[sp_Test] (
  @myID int output,
  @myFirstName nvarchar(50),
  @myLastName nvarchar(50),
  @myAddress nvarchar(50),
  @myPort int
) AS
BEGIN
    INSERT INTO Dvds (myFirstName, myLastName, myAddress, myPort)
    VALUES (@myFirstName, @myLastName, @myAddress, @myPort);

    SET @myID = SCOPE_IDENTITY();
END
GO

If you use the Connect to Database under tools in Visual Studio, you will be able to add the name of the Server and database and test the connection. Upon success you can copy the string from the bottom of the dialog.

I needed something similar, but needed the ability to get the dimensions easily and also drag/drop. I based this off of the answer @Nicolas Tyler gave and modified it from there.

The features are pinch zoom in/out, long press to vibration/highlighted drag/drop.

To use it add this CustomZoomView class to your project.

• Earlier in iOS 7.0–11.0 <Deprecated> UIKit uses the topLayoutGuide & bottomLayoutGuide which is UIView property

• iOS11+ uses safeAreaLayoutGuide which is also UIView property

• Enable Safe Area Layout Guide check box from file inspector.

• Safe areas help you place your views within the visible portion of the overall interface.

• In tvOS, the safe area also includes the screen’s overscan insets, which represent the area covered by the screen’s bezel.

• safeAreaLayoutGuide reflects the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor viewss.

• Use safe areas as an aid to laying out your content like UIButton etc.

• When designing for iPhone X, you must ensure that layouts fill the screen and aren't obscured by the device's rounded corners, sensor housing, or the indicator for accessing the Home screen.

• Make sure backgrounds extend to the edges of the display, and that vertically scrollable layouts, like tables and collections, continue all the way to the bottom.

• The status bar is taller on iPhone X than on other iPhones. If your app assumes a fixed status bar height for positioning content below the status bar, you must update your app to dynamically position content based on the user's device. Note that the status bar on iPhone X doesn't change height when background tasks like voice recording and location tracking are active print(UIApplication.shared.statusBarFrame.height)//44 for iPhone X, 20 for other iPhones

• Height of home indicator container is 34 points.

• Once you enable Safe Area Layout Guide you can see safe area constraints property listed in the interface builder.

You can set constraints with respective of self.view.safeAreaLayoutGuide as-

ObjC:

  self.demoView.translatesAutoresizingMaskIntoConstraints = NO;
    UILayoutGuide * guide = self.view.safeAreaLayoutGuide;
    [self.demoView.leadingAnchor constraintEqualToAnchor:guide.leadingAnchor].active = YES;
    [self.demoView.trailingAnchor constraintEqualToAnchor:guide.trailingAnchor].active = YES;
    [self.demoView.topAnchor constraintEqualToAnchor:guide.topAnchor].active = YES;
    [self.demoView.bottomAnchor constraintEqualToAnchor:guide.bottomAnchor].active = YES;

Swift:

   demoView.translatesAutoresizingMaskIntoConstraints = false
        if #available(iOS 11.0, *) {
            let guide = self.view.safeAreaLayoutGuide
            demoView.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
            demoView.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
            demoView.bottomAnchor.constraint(equalTo: guide.bottomAnchor).isActive = true
            demoView.topAnchor.constraint(equalTo: guide.topAnchor).isActive = true
        } else {
            NSLayoutConstraint(item: demoView, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: demoView, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: demoView, attribute: .bottom, relatedBy: .equal, toItem: view, attribute: .bottom, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: demoView, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 0).isActive = true
        }

If you are a developer, this is what you need to do:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />

$("#" + $(this).attr("name")).hide();

As stated above, many languages are available for developing in Android. Java, C, Scala, C++, several scripting languages etc. Thanks to Mono you are also able to develop using C# and the .Net framework. Here you have some speedcomparisions: http://www.youtube.com/watch?v=It8xPqkKxis

There is also an alternate solution for those who aren't afraid of using hex editors (e.g. XVI32) [thanks to Trevor for this]: in the unpacked ¹ installer executable (jdk-8uXX-windows-i586.exe in case of JDK) simply replace all occurrences of RegDeleteKeyExA (the name of API found in "new" ADVAPI32.DLL) with RegDeleteKeyA (legacy API name), followed by two hex '00's (to preserve padding/segmentation boundaries). The installer will complain about unsupported Windows version, but will work nevertheless.

For reference, the raw hex strings will be:

52 65 67 44 65 6C 65 74 65 4B 65 79 45 78 41

replaced with

52 65 67 44 65 6C 65 74 65 4B 65 79 41 00 00

Note: this procedure applies to both offline (standalone) and online (downloader) package.

^{1: some newer installer versions are packed with UPX - you'd need to unpack them first, otherwise you simply won't be able to find the hex string required}

You need to use the TO_DATE function.

SELECT TO_DATE('01/01/2004', 'MM/DD/YYYY') FROM DUAL;

I had to install RazorGenerator.Templating to get it all to work. From the NuGet console, type:

Install-Package RazorGenerator.Templating

For remove in NestJS need to add option to Shema() decorator

@Schema({ versionKey: false })

Interesting blog post here:

http://geekswithblogs.net/cskardon/archive/2008/06/23/dispose-of-a-wpf-usercontrol-ish.aspx

It mentions subscribing to Dispatcher.ShutdownStarted to dispose of your resources.

I had exactly this problem of not being able to su to root because I was running in the container as an unprivileged user.

But I didn't want to rebuild a new image as the previous answers suggest.

Instead I have found that I could access the container as root using 'nsenter', see: https://github.com/jpetazzo/nsenter

First determine the PID of your container on the host:

docker inspect --format {{.State.Pid}} <container_name_or_ID>

Then use nsenter to enter the container as root

nsenter --target <PID> --mount --uts --ipc --net --pid

You can do via Page directive.

For example:

<%@ page language="java" contentType="application/json; charset=UTF-8"
    pageEncoding="UTF-8"%>

• contentType="mimeType [ ;charset=characterSet ]" | "text/html;charset=ISO-8859-1"

The MIME type and character encoding the JSP file uses for the response it sends to the client. You can use any MIME type or character set that are valid for the JSP container. The default MIME type is text/html, and the default character set is ISO-8859-1.

It's not a better idea to override the core.common file of codeigniter. Because that's the more tested and system files....

I make a solution for this problem. In your ckeditor_helper.php file line- 65

if($k !== end (array_keys($data['config']))) {
       $return .= ",";
}

Change this to-->

 $segment = array_keys($data['config']);
    if($k !== end($segment)) {
           $return .= ",";
    }

I think this is the best solution and then your problem notice will dissappear.

The String[] args parameter is an array of Strings passed as parameters when you are running your application through command line in the OS.

So, imagine you have compiled and packaged a myApp.jar Java application. You can run your app by double clicking it in the OS, of course, but you could also run it using command line way, like (in Linux, for example):

user@computer:~$ java -jar myApp.jar

When you call your application passing some parameters, like:

user@computer:~$ java -jar myApp.jar update notify

The java -jar command will pass your Strings update and notify to your public static void main() method.

You can then do something like:

System.out.println(args[0]); //Which will print 'update'
System.out.println(args[1]); //Which will print 'notify'

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.

You can get access to the options array of a selected object by going document.getElementById("cars").options where 'cars' is the select object.

Once you have that you can call option[i].setAttribute('selected', 'selected'); to select an option.

I agree with every one else that you are better off doing this server side though.

This works for me in Visual Studio 2015.

I copy all DLL files from a folder located in a library folder on the same level as my solution folder into the targetdirectory of the project being built.

Using a relative path from my project directory and going up the folder structure two steps with..\..\lib

MySolutionFolder
....MyProject
Lib

if $(ConfigurationName) == Debug (
xcopy /Y "$(ProjectDir)..\..\lib\*.dll" "$(TargetDir)"
) ELSE (echo "Not Debug mode, no file copy from lib")

The way is

pip install [package_name] --upgrade

or in short

pip install [package_name] -U

Using sudo will ask to enter your root password to confirm the action, but although common, is considered unsafe.

If you do not have a root password (if you are not the admin) you should probably work with virtualenv.

You can also use the user flag to install it on this user only.

pip install [package_name] --upgrade --user

Thank you LSerni you solved it for me.

To achieve this :

+-----------------------------------------+
| +-------+                     +-------+ |
| | Text1 |                     | Text1 | |
| +-------+                     +-------+ |
|+----------------------------------------+

You have to do this :

<div style="overflow:auto">
    <div style="display:inline-block;float:left"> Text1 </div>
    <div style="display:inline-block;float:right"> Text2 </div>
</div>

return results == null ? 0 : ( results[1] || 0 );

https://gist.github.com/danomanion/6175687 proposes an elegant solution, using a custom bullet in place of a background image:

   a.logo {
     display: list-item;
     list-style-image: url("../images/desired-background.png");
     list-style-position: inside;
   }

By including this within a

@media print {
}

block, I'm able to replace a white-on-transparent logo on the screen, rendered as a background-image, with a black-on-transparent logo for print.

but on the other hand it creates a completely useless list of integers just to loop over them. Isn't it a waste of memory, especially as far as big numbers of iterations are concerned?

That is what xrange(n) is for. It avoids creating a list of numbers, and instead just provides an iterator object.

In Python 3, xrange() was renamed to range() - if you want a list, you have to specifically request it via list(range(n)).

Yeah ./ means the directory you're currently in.

git checkout master
git pull origin master
# Merge branch test into master
git merge test

After merging, if the file is changed, then when you merge it will through error of "Resolve Conflict"

So then you need to first resolve all your conflicts then, you have to again commit all your changes and then push

git push origin master

This is better do who has done changes in test branch, because he knew what changes he has done.

I had this error recently, when the files were excluded by settings in my SVN globals. The error was especially nasty since I also deleted the files directly from the repository - and this meant that the above solutions were refusing wouldn't work. In this case, manually deleting the .svn directory from the directory that I removed from SVN allowed me to run an update which then allowed me to commit.

Check out this code. It works in every major browser.

remove_item = function(arr, value) {
 var b = '';
 for (b in arr) {
  if (arr[b] === value) {
   arr.splice(b, 1);
   break;
  }
 }
 return arr;
};

var array = [1,3,5,6,5,9,5,3,55]
var res = remove_item(array,5);
console.log(res)

Well it depends on what you have in your table.

its one of the following If you have only one table

var count = $('#gvPerformanceResult tr').length;

If you are concerned about sub tables but this wont work with tbody and thead (if you use them)

var count = $('#gvPerformanceResult>tr').length;

Where by this will work (but is quite frankly overkill.)

var count = $('#gvPerformanceResult>tbody>tr').length;

Here is a solution which:

• Is self contained
• Does not require VBA
• Is not limited in the same way as IF regarding bucket maximums
• Does not require precise values as LOOKUP does

=INDEX({"Small","Medium","Large"},LARGE(IF([INPUT_VALUE]>{0,11,21},{1,2,3}),1))

Replace [INPUT_VALUE] with the appropriate cell reference and make sure to press Ctrl+Shift+Enter as this is an array formula.

Each of the array constants can be expanded to be arbitrarily long; as long as the formula does not exceed Excel's maximum of 8,192 characters. The first constant should contain the return values, the second should contain ordered thresholds,and the third should simply be ascending integers.

I am using something as simple as this :

if(str.startsWith("\"") && str.endsWith("\""))
        {
            str = str.substring(1, str.length()-1);
        }

Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.

Your code isn't working, because the hidden attibute is not supported in versions of IE before v11

If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:

*[hidden] { display: none; }

The Back button wasn't working for me as well, but I figured out that the problem was that I had html content inside my main page, in the ui-view element.

i.e.

<div ui-view>
     <h1> Hey Kids! </h1>
     <!-- More content -->
</div>

So I moved the content into a new .html file, and marked it as a template in the .js file with the routes.

i.e.

   .state("parent.mystuff", {
        url: "/mystuff",
        controller: 'myStuffCtrl',
        templateUrl: "myStuff.html"
    })

Call the perl binary, in search and replace per line mode ( the -pi ) by running the perl code ( the -e) in the single quotes, which iterates over the keys of the special %ENV hash containing the exported variable names as keys and the exported variable values as the keys' values and for each iteration simple replace a string containing a $<<key>> with its <<value>>.

 perl -pi -e 'foreach $key(sort keys %ENV){ s/\$$key/$ENV{$key}/g}' file

Caveat: An additional logic handling is required for cases in which two or more vars start with the same string ...

For references and the future, one should read the doc here https://dev.mysql.com/doc/mysql-secure-deployment-guide/5.7/en/secure-deployment-password-validation.html

Then you should edit your mysqld.cnf file, for instance :

vim /etc/mysql/mysql.conf.d/mysqld.cnf

Then, add in the [mysqld] part, the following :

plugin-load-add=validate_password.so
validate_password_policy=LOW

Basically, if you edit your default, it will looks like :

[mysqld]
#
# * Basic Settings
#
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
plugin-load-add=validate_password.so
validate_password_policy=LOW

Then, you can restart:

systemctl restart mysql

If you forget the plugin-load-add=validate_password.so part, you will it an error at restart.

Enjoy !

I think you should do it the other way round. Define your Divs and have your a href within each Div, pointing to different links

The easiest way is to use a for loop template tag.

Given the view:

def MyView(request):
    ...
    query_results = YourModel.objects.all()
    ...
    #return a response to your template and add query_results to the context

You can add a snippet like this your template...

<table>
    <tr>
        <th>Field 1</th>
        ...
        <th>Field N</th>
    </tr>
    {% for item in query_results %}
    <tr> 
        <td>{{ item.field1 }}</td>
        ...
        <td>{{ item.fieldN }}</td>
    </tr>
    {% endfor %}
</table>

This is all covered in Part 3 of the Django tutorial. And here's Part 1 if you need to start there.

Use : instead of =

see the example below that gives an error

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name = filter.clean(req.body.name.toString()),
        content = filter.clean(req.body.content.toString()),
        created: new Date()
    };

That gives Syntex Error: invalid shorthand proprty initializer.

Then i replace = with : that's solve this error.

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name: filter.clean(req.body.name.toString()),
        content: filter.clean(req.body.content.toString()),
        created: new Date()
    };

use sed's -i option, e.g.

sed -i bak -e s/STRING_TO_REPLACE/REPLACE_WITH/g index.html

To understand what is going on, let's take one letter(repeated more than once) in the sentence string and follow what happens when it goes through the loop.

Remember that we start off with an empty characters dictionary

characters = {}

I will pick the letter 'e'. Let's pass the character 'e' (found in the word The) for the first time through the loop. I will assume it's the first character to go through the loop and I'll substitute the variables with their values:

for 'e' in "The quick brown fox jumped over the lazy dog.":
    {}['e'] = {}.get('e', 0) + 1 

characters.get('e', 0) tells python to look for the key 'e' in the dictionary. If it's not found it returns 0. Since this is the first time 'e' is passed through the loop, the character 'e' is not found in the dictionary yet, so the get method returns 0. This 0 value is then added to the 1 (present in the characters[character] = characters.get(character,0) + 1 equation). After completion of the first loop using the 'e' character, we now have an entry in the dictionary like this: {'e': 1}

The dictionary is now:

characters = {'e': 1}

Now, let's pass the second 'e' (found in the word jumped) through the same loop. I'll assume it's the second character to go through the loop and I'll update the variables with their new values:

for 'e' in "The quick brown fox jumped over the lazy dog.":
    {'e': 1}['e'] = {'e': 1}.get('e', 0) + 1

Here the get method finds a key entry for 'e' and finds its value which is 1. We add this to the other 1 in characters.get(character, 0) + 1 and get 2 as result.

When we apply this in the characters[character] = characters.get(character, 0) + 1 equation:

characters['e'] = 2

It should be clear that the last equation assigns a new value 2 to the already present 'e' key. Therefore the dictionary is now:

characters = {'e': 2}

On your DBA account, give USERB the right to create a procedure using grant grant create any procedure to USERB

The procedure will look

CREATE OR REPLACE PROCEDURE USERB.USERB_PROCEDURE
--Must add the line below
AUTHID CURRENT_USER AS
  BEGIN
  --DO SOMETHING HERE
  END
END

GRANT EXECUTE ON USERB.USERB_PROCEDURE TO USERA

I know this is a very old question but I am hoping I could chip it a bit.

Beside commands like M-x eval-buffer or M-x load-file you can restart a fresh emacs from the command line:

emacs -q --load "init.el"

Usage example stackoverflow.com/questions/44959535/company-backends-in-gnu-emacs/

You can use object.rowIndex property which has an index starting at 0.

$("table tr").click(function(){
    alert (this.rowIndex);
});

See a working demo

not so elegant but you dont need to declare any variable:

for k in (select max(1) from table where 1 = 1) loop
    update x where column = value;
end loop;

As per my current condition, I follow this approach. I want to give identity to a primary table after data inserted via script.

As I want to append identity, so it always start from 1 to End of record count that I want.

--first drop column and add with identity
ALTER TABLE dbo.tblProductPriceList drop column ID 
ALTER TABLE dbo.tblProductPriceList add ID INT IDENTITY(1,1)

--then add primary key to that column (exist option you can ignore)
IF  NOT EXISTS (SELECT * FROM sys.key_constraints  WHERE object_id = OBJECT_ID(N'[dbo].[PK_tblProductPriceList]') AND parent_object_id = OBJECT_ID(N'[dbo].[tblProductPriceList]'))
    ALTER TABLE [tblProductPriceList] ADD PRIMARY KEY (id)
GO

This will create the same primary key column with identity

I used this links : https://blog.sqlauthority.com/2014/10/11/sql-server-add-auto-incremental-identity-column-to-table-after-creating-table/

Add primary key to existing table

This error happens when you send 2 responses. For example :

if(condition A)
{ 

      res.render('Profile', {client:client_});

}

if (condition B){

      res.render('Profile', {client:client_});
    }
  }

Imagine if for some reason condition A and B are true so in the second render you'll get that error

In my case MySQL sever was not running. I restarted the MySQL server and issue was resolved.

//on ubuntu server
sudo /etc/init.d/mysql start

To avoid MySQL stop problem, you can use the "initctl" utility in Ubuntu 14.04 LTS Linux to make sure the service restarts in case of a failure or reboot. Please consider talking a snapshot of root volume (with mysql stopped) before performing this operations for data retention purpose[8]. You can use the following commands to manage the mysql service with "initctl" utility with stop and start operations.

$ sudo initctl stop mysql
$ sudo initctl start mysql

To verify the working, you can check the status of the service and get the process id (pid), simulate a failure by killing the "mysql" process and verify its status as running with new process id after sometime (typically within 1 minute) using the following commands.

$ sudo initctl status mysql         # get pid
$ sudo kill -9 <pid>                # kill mysql process
$ sudo initctl status mysql         # verify status as running after sometime

Note : In latest Ubuntu version now initctl is replaced by systemctl

I came to this post by way of better understanding the inference of the infamous quote from Mac Lane's Category Theory For the Working Mathematician.

In describing what something is, it's often equally useful to describe what it's not.

The fact that Mac Lane uses the description to describe a Monad, one might imply that it describes something unique to monads. Bear with me. To develop a broader understanding of the statement, I believe it needs to be made clear that he is not describing something that is unique to monads; the statement equally describes Applicative and Arrows among others. For the same reason we can have two monoids on Int (Sum and Product), we can have several monoids on X in the category of endofunctors. But there is even more to the similarities.

Both Monad and Applicative meet the criteria:

• endo => any arrow, or morphism that starts and ends in the same place
• functor => any arrow, or morphism between two Categories

  (e.g., in day to day Tree a -> List b, but in Category Tree -> List)

• monoid => single object; i.e., a single type, but in this context, only in regards to the external layer; so, we can't have Tree -> List, only List -> List.

The statement uses "Category of..." This defines the scope of the statement. As an example, the Functor Category describes the scope of f * -> g *, i.e., Any functor -> Any functor, e.g., Tree * -> List * or Tree * -> Tree *.

What a Categorical statement does not specify describes where anything and everything is permitted.

In this case, inside the functors, * -> * aka a -> b is not specified which means Anything -> Anything including Anything else. As my imagination jumps to Int -> String, it also includes Integer -> Maybe Int, or even Maybe Double -> Either String Int where a :: Maybe Double; b :: Either String Int.

So the statement comes together as follows:

• functor scope :: f a -> g b (i.e., any parameterized type to any parameterized type)
• endo + functor :: f a -> f b (i.e., any one parameterized type to the same parameterized type) ... said differently,
• a monoid in the category of endofunctor

So, where is the power of this construct? To appreciate the full dynamics, I needed to see that the typical drawings of a monoid (single object with what looks like an identity arrow, :: single object -> single object), fails to illustrate that I'm permitted to use an arrow parameterized with any number of monoid values, from the one type object permitted in Monoid. The endo, ~ identity arrow definition of equivalence ignores the functor's type value and both the type and value of the most inner, "payload" layer. Thus, equivalence returns true in any situation where the functorial types match (e.g., Nothing -> Just * -> Nothing is equivalent to Just * -> Just * -> Just * because they are both Maybe -> Maybe -> Maybe).

Sidebar: ~ outside is conceptual, but is the left most symbol in f a. It also describes what "Haskell" reads-in first (big picture); so Type is "outside" in relation to a Type Value. The relationship between layers (a chain of references) in programming is not easy to relate in Category. The Category of Set is used to describe Types (Int, Strings, Maybe Int etc.) which includes the Category of Functor (parameterized Types). The reference chain: Functor Type, Functor values (elements of that Functor's set, e.g., Nothing, Just), and in turn, everything else each functor value points to. In Category the relationship is described differently, e.g., return :: a -> m a is considered a natural transformation from one Functor to another Functor, different from anything mentioned thus far.

Back to the main thread, all in all, for any defined tensor product and a neutral value, the statement ends up describing an amazingly powerful computational construct born from its paradoxical structure:

• on the outside it appears as a single object (e.g., :: List); static
• but inside, permits a lot of dynamics
  • any number of values of the same type (e.g., Empty | ~NonEmpty) as fodder to functions of any arity. The tensor product will reduce any number of inputs to a single value... for the external layer (~fold that says nothing about the payload)
  • infinite range of both the type and values for the inner most layer

In Haskell, clarifying the applicability of the statement is important. The power and versatility of this construct, has absolutely nothing to do with a monad per se. In other words, the construct does not rely on what makes a monad unique.

When trying to figure out whether to build code with a shared context to support computations that depend on each other, versus computations that can be run in parallel, this infamous statement, with as much as it describes, is not a contrast between the choice of Applicative, Arrows and Monads, but rather is a description of how much they are the same. For the decision at hand, the statement is moot.

This is often misunderstood. The statement goes on to describe join :: m (m a) -> m a as the tensor product for the monoidal endofunctor. However, it does not articulate how, in the context of this statement, (<*>) could also have also been chosen. It truly is a an example of six/half dozen. The logic for combining values are exactly alike; same input generates the same output from each (unlike the Sum and Product monoids for Int because they generate different results when combining Ints).

So, to recap: A monoid in the category of endofunctors describes:

   ~t :: m * -> m * -> m *
   and a neutral value for m *

(<*>) and (>>=) both provide simultaneous access to the two m values in order to compute the the single return value. The logic used to compute the return value is exactly the same. If it were not for the different shapes of the functions they parameterize (f :: a -> b versus k :: a -> m b) and the position of the parameter with the same return type of the computation (i.e., a -> b -> b versus b -> a -> b for each respectively), I suspect we could have parameterized the monoidal logic, the tensor product, for reuse in both definitions. As an exercise to make the point, try and implement ~t, and you end up with (<*>) and (>>=) depending on how you decide to define it forall a b.

If my last point is at minimum conceptually true, it then explains the precise, and only computational difference between Applicative and Monad: the functions they parameterize. In other words, the difference is external to the implementation of these type classes.

In conclusion, in my own experience, Mac Lane's infamous quote provided a great "goto" meme, a guidepost for me to reference while navigating my way through Category to better understand the idioms used in Haskell. It succeeds at capturing the scope of a powerful computing capacity made wonderfully accessible in Haskell.

However, there is irony in how I first misunderstood the statement's applicability outside of the monad, and what I hope conveyed here. Everything that it describes turns out to be what is similar between Applicative and Monads (and Arrows among others). What it doesn't say is precisely the small but useful distinction between them.

Simple ... use OSGi. In OSGi you can iterate over your Bundle's entries with findEntries and findPaths.

You can do it with a separate UPDATE statement

UPDATE report.TEST target
SET    is Deleted = 'Y'
WHERE  NOT EXISTS (SELECT 1
                   FROM   main.TEST source
                   WHERE  source.ID = target.ID);

I don't know of any way to integrate this into your MERGE statement.

The mentioned keywords are access modifiers and help us implement Encapsulation (or information hiding). They tell the compiler which other classes should have access to the field or method being defined.

private - Only the current class will have access to the field or method.

protected - Only the current class and subclasses (and sometimes also same-package classes) of this class will have access to the field or method.

public - Any class can refer to the field or call the method.

Here is an awesome and precise explanation I found.

TIMESTAMP used to track changes of records, and update every time when the record is changed. DATETIME used to store specific and static value which is not affected by any changes in records.

TIMESTAMP also affected by different TIME ZONE related setting. DATETIME is constant.

TIMESTAMP internally converted a current time zone to UTC for storage, and during retrieval convert the back to the current time zone. DATETIME can not do this.

TIMESTAMP is 4 bytes and DATETIME is 8 bytes.

TIMESTAMP supported range: ‘1970-01-01 00:00:01' UTC to ‘2038-01-19 03:14:07' UTC DATETIME supported range: ‘1000-01-01 00:00:00' to ‘9999-12-31 23:59:59'

I'm so surprised no one has mentioned the standard way in Posix

Please use basename / dirname constructs.

man basename

Have in mind though, that getExternalStorageDirectory() is not going to work properly on some phones e.g. my Motorola razr maxx, as it has 2 cards /mnt/sdcard and /mnt/sdcard-ext - for internal and external SD cards respectfully. You will be getting the /mnt/sdcard only reply every time. Google must provide a way to deal with such a situation. As it renders many SD card aware apps (i.e card backup) failing miserably on these phones.

This also works, and doesn't require a /path/to/file URI conversion. If the file is on the classpath, this will find it.

File currFile = new File(getClass().getClassLoader().getResource("the_file.txt").getFile());

Try below:

SELECT CONVERT(VARCHAR(20), GETDATE(), 101)

Many answers on starting something at boot, but often you want to start it just a little later, because your script depends on e.g. networking. Use at to just add this delay, e.g.:

at now + 1 min -f /path/yourscript

You may add this in /etc/rc.local, but also in cron like:

# crontab -e
@reboot at now + 1 min -f /path/yourscript

Isn't it fun to combine cron and at? Info is in the man page man at.

As for the comments that @reboot may not be widely supported, just try it. I found out that /etc/rc.local has become obsolete on distros that support systemd, such as ubuntu and raspbian.

For Laravel 5.2 >=

use the Eloquent method:

inRandomOrder()

The inRandomOrder method may be used to sort the query results randomly. For example, you may use this method to fetch a random user:

$randomUser = DB::table('users')
            ->inRandomOrder()
            ->first();

from docs: https://laravel.com/docs/5.2/queries#ordering-grouping-limit-and-offset

As all the other answers show, the problem is that adding a std::string and a const char* using + results in a std::string, while system() expects a const char*. And the solution is to use c_str(). However, you can also do it without a temporary:

string name = "john";
system((" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str());

In Python self is the conventional name given to the first argument of instance methods of classes, which is always the instance the method was called on:

class A(object):
  def f(self):
    print self

a = A()
a.f()

Will give you something like

<__main__.A object at 0x02A9ACF0>

Declare variable to assign value returned from setInterval(...) and pass the assigned variable to clearInterval();

e.g.

var timer, intervalInSec = 2;

timer = setInterval(func, intervalInSec*1000, 30 ); // third parameter is argument to called function 'func'

function func(param){
   console.log(param);
}

// Anywhere you've access to timer declared above call clearInterval

$('.htmlelement').click( function(){  // any event you want

       clearInterval(timer);// Stops or does the work
});

Double them to escape;

SELECT *
  FROM Header
 WHERE userID LIKE '%''%'

$(document).ready(function() {
 $('#content').load('your_url_here');
});

You need to set

document["pic1"].src = searchPic.src;

The searchPic itself is your Image(), you need to read the src that you set.

I believe that this question deserves an updated. Just compare with other approaches.

Here's how you do redirection (3xx) from one url to another in Flask (0.12.2):

#!/usr/bin/env python

from flask import Flask, redirect

app = Flask(__name__)

@app.route("/")
def index():
    return redirect('/you_were_redirected')

@app.route("/you_were_redirected")
def redirected():
    return "You were redirected. Congrats :)!"

if __name__ == "__main__":
    app.run(host="0.0.0.0",port=8000,debug=True)

Try to use the func below to add colorbar:

def add_colorbar(mappable):
    from mpl_toolkits.axes_grid1 import make_axes_locatable
    import matplotlib.pyplot as plt
    last_axes = plt.gca()
    ax = mappable.axes
    fig = ax.figure
    divider = make_axes_locatable(ax)
    cax = divider.append_axes("right", size="5%", pad=0.05)
    cbar = fig.colorbar(mappable, cax=cax)
    plt.sca(last_axes)
    return cbar

Then you codes need to be modified as:

fig , ( (ax1,ax2) , (ax3,ax4)) = plt.subplots(2, 2,sharex = True,sharey=True)
z1_plot = ax1.scatter(x,y,c = z1,vmin=0.0,vmax=0.4)
add_colorbar(z1_plot)

Sometimes changing the header is not enough, some sites check the referer as well:

curl -v \
     -H 'Host: restapi.some-site.com' \
     -H 'Connection: keep-alive' \
     -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' \
     -H 'Accept-Language: en-GB,en-US;q=0.8,en;q=0.6' \
     -e localhost \
     -A 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.65 Safari/537.36' \
     'http://restapi.some-site.com/getsomething?argument=value&argument2=value'

In this example the referer (-e or --referer in curl) is 'localhost'.

Make sure that your <td> is not display: block;

Floating will do this, but much easier to just: display: inline;

You can post large amount of data by setting php.ini variable: max_input_vars Default size of this variable is 1000 but if you want to sent large amount of data you have to increase the size accordingly. If you can't set the size from ini_set you have to do it through htaccess or by doing changes into php.ini file directly.

max_input_vars  2500
memory_limit    256M

• The children of a row-flexbox container automatically fill the container's vertical space.

• Specify flex: 1; for a child if you want it to fill the remaining horizontal space:

I used fgm's solution (thanks fgm!), but needed to eliminate the tab characters at the end of each row, so modified the script thus:

#!/bin/bash 
declare -a array=( )                      # we build a 1-D-array

read -a line < "$1"                       # read the headline

COLS=${#line[@]}                          # save number of columns

index=0
while read -a line; do
    for (( COUNTER=0; COUNTER<${#line[@]}; COUNTER++ )); do
        array[$index]=${line[$COUNTER]}
        ((index++))
    done
done < "$1"

for (( ROW = 0; ROW < COLS; ROW++ )); do
  for (( COUNTER = ROW; COUNTER < ${#array[@]}; COUNTER += COLS )); do
    printf "%s" ${array[$COUNTER]}
    if [ $COUNTER -lt $(( ${#array[@]} - $COLS )) ]
    then
        printf "\t"
    fi
  done
  printf "\n" 
done

What makes jQuery easy to use is that you don't have to apply attributes to each element. The jQuery object contains an array of elements, and the methods of the jQuery object applies the same attributes to all the elements in the array.

There is also a shorter form for $(document).ready(function(){...}) in $(function(){...}).

So, this is all you need:

$(function(){
  $('div.easy_editor').css('border','9px solid red');
});

If you want the code to work for any element with that class, you can just specify the class in the selector without the tag name:

$(function(){
  $('.easy_editor').css('border','9px solid red');
});

If you don't have any fancy gem action, but do have JSON, this CLI line will work on a hash:

puts JSON.pretty_generate(my_hash).gsub(":", " =>")

#=>
{
  :key1 => "value1",

  :key2 => "value2",

  :key3 => "value3"
}

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

In c# 9.0 you can try to use records for this. They have default copy constructor that copy all fields - no need to use reflection / constructor with all fields.

public record BaseR
{
   public string Prop1 { get; set; }
}

public record DerivedR : BaseR
{
   public DerivedR(BaseR baseR) : base(baseR) { }
   public string Prop2 { get; set; }
}

var baseR = new BaseR { Prop1 = "base prob" };
var derivedR = new DerivedR(baseR) { Prop2 = "new prop" };

Examples from Apache use this:

CloseableHttpClient httpclient = HttpClients.createDefault();

The class org.apache.http.impl.client.HttpClients is there since version 4.3.

The code for HttpClients.createDefault() is the same as the accepted answer in here.

For Hadoop 3.x, if you try to create a file on HDFS when unauthenticated (e.g. user=dr.who) you will get this error.

It is not recommended for systems that need to be secure, however if you'd like to disable file permissions entirely in Hadoop 3 the hdfs-site.xml setting has changed to:

<property>
  <name>dfs.permissions.enabled</name>
  <value>false</value>
</property>

If you want to convert the HTML special characters and not just remove them as well as strip things down and prepare for plain text this was the solution that worked for me...

function htmlToPlainText($str){
    $str = str_replace(' ', ' ', $str);
    $str = html_entity_decode($str, ENT_QUOTES | ENT_COMPAT , 'UTF-8');
    $str = html_entity_decode($str, ENT_HTML5, 'UTF-8');
    $str = html_entity_decode($str);
    $str = htmlspecialchars_decode($str);
    $str = strip_tags($str);

    return $str;
}

$string = '<p>this is (&nbsp;) a test</p>
<div>Yes this is! &amp; does it get "processed"? </div>'

htmlToPlainText($string);
// "this is ( ) a test. Yes this is! & does it get processed?"`

html_entity_decode w/ ENT_QUOTES | ENT_XML1 converts things like ' htmlspecialchars_decode converts things like & html_entity_decode converts things like '< and strip_tags removes any HTML tags left over.

jQuerify is the perfect extension to embed jQuery into Chrome Console and is as simple as you can imagine. This extension also indicates if jQuery has been already embedded into a page.

This extension is used to embed jQuery into any page you want. It allows to use jQuery in the console shell (You can invoke Chrome console by Ctrl + Shift + j".).

To embed jQuery into the selected tab click on extension button.

It's working completely try this:

<div class="button pull-left" style="padding-left:40%;" >

The other answers are what you asked about, but in case it’s useful to anyone else, here’s how to set the font conditionally from the screen DPI (Windows only):

set guifont=default
if has('windows')
    "get dpi, strip out utf-16 garbage and new lines
    "system() converts 0x00 to 0x01 for 'platform independence'
    "should return something like 'PixelsPerXLogicalInch=192'
    "get the part from the = to the end of the line (eg '=192') and strip
    "the first character
    "and convert to a number
    let dpi = str2nr(strpart(matchstr(substitute(
        \system('wmic desktopmonitor get PixelsPerXLogicalInch /value'),
        \'\%x01\|\%x0a\|\%x0a\|\%xff\|\%xfe', '', 'g'),
        \'=.*$'), 1))
    if dpi > 100
        set guifont=high_dpi_font
    endif
endif

You can use rails dbconsole to view the database that your rails application is using. It's alternative answer rails db. Both commands will direct you the command line interface and will allow you to use that database query syntax.

I was getting nothing for any $_GET["..."] (e.g print_r($_GET) gave an empty array) yet $_SERVER['REQUEST_URI'] showed stuff should be there. In the end it turned out that I was only getting to the web page because my .htaccess was redirecting it there (my 404 handler was the same .php file, and I had made a typo in the browser when testing).

Simply changing the name meant the same php code worked once the 404 redirection wasn't kicking in!

So there are ways $_GET can return nothing even though the php code may be correct.

I just stumbled onto this issue accessing some Python libraries: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools". The latest link to that is actually here: https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2019

When you begin the installer, it will have several "options" enabled which will balloon the install size to 5gb. If you have Windows 10, you'll need to leave selected the "Windows 10 SDK" option as mentioned here.

I hope it helps save others time!

Following @thomas-jungblut implementation in python, i did the same for Octave. If you find something wrong please let me know and i will fix+update.

Data comes from a txt file with the following rows:

1 10 1000
2 20 2500
3 25 3500
4 40 5500
5 60 6200

think about it as a very rough sample for features [number of bedrooms] [mts2] and last column [rent price] which is what we want to predict.

Here is the Octave implementation:

% Initial theta values
theta = ones(n + 1, 1);

% Number of training samples
m = length(DATA(:, 1));

% X with one mor column (x0 filled with '1's)
X = ones(m, 1);
for i = 1:n
  X = [X, DATA(:,i)];
endfor

% Expected data must go always in the last column  
y = DATA(:, n + 1)

function gradientDescent(x, y, theta, alphaNum, iterations)
  iterations = [];
  costs = [];

  m = length(y);

  for iteration = 1:10000
    hypothesis = x * theta;

    loss = hypothesis - y;

    % J(theta)    
    cost = sum(loss.^2) / (2 * m);

    % Save for the graphic to see if the algorithm did work
    iterations = [iterations, iteration];
    costs = [costs, cost];

    gradient = (x' * loss) / m; % /m is for the average

    theta = theta - (alphaNum * gradient);
  endfor    

  % Show final theta values
  display(theta)

  % Show J(theta) graphic evolution to check it worked, tendency must be zero
  plot(iterations, costs);

endfunction

% Execute gradient descent
gradientDescent(X, y, theta, alphaNum, iterations);

To go along with what v01d said:

Using Android Studio for Mac OS X, the SDK folder could also be at /Users/{user}/Library/Android/sdk, where {user} is your username.

To find out where the partial SDK installation is, go to Configure > SDK Manager in Android Studio, then click edit at the top. This should pop up a window and show the location.

Copy this path and paste it front of the cd command in a terminal. Finally execute sudo ./android sdk to launch the standalone SDK manager.

EDIT (July 14, 2016):

The "android" binary file could also be at /Users/{user}/Library/Android/sdk/tools.

I would just like to expand upon the top answer, which uses GNUPlot to create a bar graph, for absolute beginners because I read the answer and was still confused from the deluge of syntax.

We begin by writing a text file of GNUplot commands. Lets call it commands.txt:

set term png
set output "graph.png"
set boxwidth 0.5
set style fill solid
plot "data.dat" using 1:3:xtic(2) with boxes

set term png will set GNUplot to output a .png file and set output "graph.png" is the name of the file it will output to.

The next two lines are rather self explanatory. The fifth line contains a lot of syntax.

plot "data.dat" using 1:3:xtic(2) with boxes

"data.dat" is the data file we are operating on. 1:3 indicates we will be using column 1 of data.dat for the x-coordinates and column 3 of data.dat for the y-coordinates. xtic() is a function that is responsible for numbering/labeling the x-axis. xtic(2), therefore, indicates that we will be using column 2 of data.dat for labels.

"data.dat" looks like this:

0 label       100
1 label2      450
2 "bar label" 75

To plot the graph, enter gnuplot commands.txt in terminal.

Object.create is not yet standard on several browsers, for example IE8, Opera v11.5, Konq 4.3 do not have it. You can use Douglas Crockford's version of Object.create for those browsers but this doesn't include the second 'initialisation object' parameter used in CMS's answer.

For cross browser code one way to get object initialisation in the meantime is to customise Crockford's Object.create. Here is one method:-

Object.build = function(o) {
   var initArgs = Array.prototype.slice.call(arguments,1)
   function F() {
      if((typeof o.init === 'function') && initArgs.length) {
         o.init.apply(this,initArgs)
      }
   }
   F.prototype = o
   return new F()
}

This maintains Crockford prototypal inheritance, and also checks for any init method in the object, then runs it with your parameter(s), like say new man('John','Smith'). Your code then becomes:-

MY_GLOBAL = {i: 1, nextId: function(){return this.i++}}  // For example

var userB = {
    init: function(nameParam) {
        this.id = MY_GLOBAL.nextId();
        this.name = nameParam;
    },
    sayHello: function() {
        console.log('Hello '+ this.name);
    }
};
var bob = Object.build(userB, 'Bob');  // Different from your code
bob.sayHello();

So bob inherits the sayHello method and now has own properties id=1 and name='Bob'. These properties are both writable and enumerable of course. This is also a much simpler way to initialise than for ECMA Object.create especially if you aren't concerned about the writable, enumerable and configurable attributes.

For initialisation without an init method the following Crockford mod could be used:-

Object.gen = function(o) {
   var makeArgs = arguments 
   function F() {
      var prop, i=1, arg, val
      for(prop in o) {
         if(!o.hasOwnProperty(prop)) continue
         val = o[prop]
         arg = makeArgs[i++]
         if(typeof arg === 'undefined') break
         this[prop] = arg
      }
   }
   F.prototype = o
   return new F()
}

This fills the userB own properties, in the order they are defined, using the Object.gen parameters from left to right after the userB parameter. It uses the for(prop in o) loop so, by ECMA standards, the order of property enumeration cannot be guaranteed the same as the order of property definition. However, several code examples tested on (4) major browsers show they are the same, provided the hasOwnProperty filter is used, and sometimes even if not.

MY_GLOBAL = {i: 1, nextId: function(){return this.i++}};  // For example

var userB = {
   name: null,
   id: null,
   sayHello: function() {
      console.log('Hello '+ this.name);
   }
}

var bob = Object.gen(userB, 'Bob', MY_GLOBAL.nextId());

Somewhat simpler I would say than Object.build since userB does not need an init method. Also userB is not specifically a constructor but looks like a normal singleton object. So with this method you can construct and initialise from normal plain objects.

None of the current solutions worked for me with git bash 2.26.2. This should work in any case if you are using the windows credential manager.

One issue is the windows credential manager runs for the logged user. In my case for example, I run git bash with right click, run as admin. Therefore, my stored credentials are in a credentials manager which I can't access with the windows GUI if I don't login to windows as admin.

To fix this:

• Open a cmd as admin (or whatever user you run with bash with)
• Go to windows/system32
• Type cmdkey /list. Your old credentials should appear here, with a part that reads ...target:xxx...
• Type cmdkey /delete:xxx, where xxx is the target from the previous line

It should confirm you that your credentials have been removed. Next time you do any operation in git bash that requires authentication, a popup will ask for your credentials.

I was over-complicating myself. After taking a long break and coming back, the desired output could be accomplished by this simple query:

SELECT Sandwiches.[Sandwich Type], Sandwich.Bread, Count(Sandwiches.[SandwichID]) AS [Total Sandwiches]
FROM Sandwiches
GROUP BY Sandwiches.[Sandwiches Type], Sandwiches.Bread;

Thanks for answering, it helped my train of thought.

Adding to assylias's answer - assylias shows us D.ITEMS is a method that returns an array. Knowing that, we don't need the variant array a(i) [See caveat below]. We just need to use the proper array syntax.

For i = 0 To d.Count - 1
    s = d.Items()(i)
    Debug.Print s
Next i()

KEYS works the same way

For i = 0 To d.Count - 1
    Debug.Print d.Keys()(i), d.Items()(i)
Next i

This syntax is also useful for the SPLIT function which may help make this clearer. SPLIT also returns an array with lower bounds at 0. Thus, the following prints "C".

Debug.Print Split("A,B,C,D", ",")(2)

SPLIT is a function. Its parameters are in the first set of parentheses. Methods and Functions always use the first set of parentheses for parameters, even if no parameters are needed. In the example SPLIT returns the array {"A","B","C","D"}. Since it returns an array we can use a second set of parentheses to identify an element within the returned array just as we would any array.

Caveat: This shorter syntax may not be as efficient as using the variant array a() when iterating through the entire dictionary since the shorter syntax invokes the dictionary's Items method with each iteration. The shorter syntax is best for plucking a single item by number from a dictionary.

You have to add the original repo as an upstream.

It is all well described here: https://help.github.com/articles/fork-a-repo

git remote add upstream https://github.com/octocat/Spoon-Knife.git
git fetch upstream
git merge upstream/master
git push origin master

I also prefer Criteria Queries for dynamic queries. But I prefer hql for delete queries, for example if delete all records from child table for parent id 'xyz', It is easily achieved by HQL, but for criteria API first we must fire n number of delete query where n is number of child table records.

@Solution ((double) rand() / (RAND_MAX+1)) * (max-min+1) + min

Warning: Don't forget due to stretching and possible precision errors (even if RAND_MAX were large enough), you'll only be able to generate evenly distributed "bins" and not all numbers in [min,max].

@Solution: Bigrand

Warning: Note that this doubles the bits, but still won't be able to generate all numbers in your range in general, i.e., it is not necessarily true that BigRand() will generate all numbers between in its range.

Info: Your approach (modulo) is "fine" as long as the range of rand() exceeds your interval range and rand() is "uniform". The error for at most the first max - min numbers is 1/(RAND_MAX +1).

Also, I suggest to switch to the new random packagee in C++11 too, which offers better and more varieties of implementations than rand().

SyntaxError: Unexpected token < in JSON at position 0

You are getting an html file instead of json.

Html files begin with <!DOCTYPE html>.

I "achieved" this error by forgetting the https:// in my fetch method:

fetch(`/api.github.com/users/${login}`)
    .then(response => response.json())
    .then(setData);

I verified my hunch:

I logged the response as text instead of JSON.

fetch(`/api.github.com/users/${login}`)
    .then(response => response.text())
    .then(text => console.log(text))
    .then(setData);

Yep, an html file.

Solution:

I fixed the error by adding back the https:// in my fetch method.

fetch(`https://api.github.com/users/${login}`)
    .then(response => response.json())
    .then(setData)
    .catch(error => (console.log(error)));

This worked for me: Type npm audit fix in the commandline. Afterwards I was able to use ng serve --open again.

the easiest way to get the global root (assuming you use NPM to run your node.js app 'npm start', etc)

var appRoot = process.env.PWD;

If you want to cross-verify the above

Say you want to cross-check process.env.PWD with the settings of you node.js application. if you want some runtime tests to check the validity of process.env.PWD, you can cross-check it with this code (that I wrote which seems to work well). You can cross-check the name of the last folder in appRoot with the npm_package_name in your package.json file, for example:

    var path = require('path');

    var globalRoot = __dirname; //(you may have to do some substring processing if the first script you run is not in the project root, since __dirname refers to the directory that the file is in for which __dirname is called in.)

    //compare the last directory in the globalRoot path to the name of the project in your package.json file
    var folders = globalRoot.split(path.sep);
    var packageName = folders[folders.length-1];
    var pwd = process.env.PWD;
    var npmPackageName = process.env.npm_package_name;
    if(packageName !== npmPackageName){
        throw new Error('Failed check for runtime string equality between globalRoot-bottommost directory and npm_package_name.');
    }
    if(globalRoot !== pwd){
        throw new Error('Failed check for runtime string equality between globalRoot and process.env.PWD.');
    }

you can also use this NPM module: require('app-root-path') which works very well for this purpose

I would create separate images for each one:

LDPI should be 36 x 36.

MDPI should be 48 x 48.

TVDPI should be 64 x 64.

HDPI should be 72 x 72.

XHDPI should be 96 x 96.

XXHDPI should be 144 x 144.

XXXHDPI should be 192 x 192.

Then just put each of them in the separate stalks of the drawable folder.

You are also required to give a large version of your icon when uploading your app onto the Google Play Store and this should be WEB 512 x 512. This is so large so that Google can rescale it to any size in order to advertise your app throughout the Google Play Store and not add pixelation to your logo.

Basically, all of the other icons should be in proportion to the 'baseline' icon, MDPI at 48 x 48.

LDPI is MDPI x 0.75.

TVDPI is MDPI x 1.33.

HDPI is MDPI x 1.5.

XHDPI is MDPI x 2.

XXHDPI is MDPI x 3.

XXXHDPI is MDPI x 4.

This is all explained on the Iconography page of the Android Developers website: http://developer.android.com/design/style/iconography.html

A few caveats not covered in most answers:

• Check against multiple items (some should be deleted, some should remain)
• Skip the first option (-Select-) on some option lists

A take on these:

const eligibleOptions = ['800000002', '800000001'];
let optionsList = document.querySelector("select#edit-salutation");
for (let i = 1; i<optionsList.length; i++) {
    if(eligibleOptions.indexOf(optionsList.options[i].value) === -1) {
        cbxSal.remove(i);
        i--;
    }
}

use this code

var sid = $(this);
sid.attr('checked','checked');

var consolidatedChildren =
    from c in children
    group c by new
    {
        c.School,
        c.Friend,
        c.FavoriteColor,
    } into gcs
    select new ConsolidatedChild()
    {
        School = gcs.Key.School,
        Friend = gcs.Key.Friend,
        FavoriteColor = gcs.Key.FavoriteColor,
        Children = gcs.ToList(),
    };

var consolidatedChildren =
    children
        .GroupBy(c => new
        {
            c.School,
            c.Friend,
            c.FavoriteColor,
        })
        .Select(gcs => new ConsolidatedChild()
        {
            School = gcs.Key.School,
            Friend = gcs.Key.Friend,
            FavoriteColor = gcs.Key.FavoriteColor,
            Children = gcs.ToList(),
        });

Use Python method datetime.strftime(format), where format = '%Y-%m-%d %H:%M:%S'.

import datetime

now = datetime.datetime.utcnow()

cursor.execute("INSERT INTO table (name, id, datecolumn) VALUES (%s, %s, %s)",
               ("name", 4, now.strftime('%Y-%m-%d %H:%M:%S')))

Timezones

If timezones are a concern, the MySQL timezone can be set for UTC as follows:

cursor.execute("SET time_zone = '+00:00'")

And the timezone can be set in Python:

now = datetime.datetime.utcnow().replace(tzinfo=datetime.timezone.utc)

MySQL Documentation

MySQL recognizes DATETIME and TIMESTAMP values in these formats:

As a string in either 'YYYY-MM-DD HH:MM:SS' or 'YY-MM-DD HH:MM:SS' format. A “relaxed” syntax is permitted here, too: Any punctuation character may be used as the delimiter between date parts or time parts. For example, '2012-12-31 11:30:45', '2012^12^31 11+30+45', '2012/12/31 11*30*45', and '2012@12@31 11^30^45' are equivalent.

The only delimiter recognized between a date and time part and a fractional seconds part is the decimal point.

The date and time parts can be separated by T rather than a space. For example, '2012-12-31 11:30:45' '2012-12-31T11:30:45' are equivalent.

As a string with no delimiters in either 'YYYYMMDDHHMMSS' or 'YYMMDDHHMMSS' format, provided that the string makes sense as a date. For example, '20070523091528' and '070523091528' are interpreted as '2007-05-23 09:15:28', but '071122129015' is illegal (it has a nonsensical minute part) and becomes '0000-00-00 00:00:00'.

As a number in either YYYYMMDDHHMMSS or YYMMDDHHMMSS format, provided that the number makes sense as a date. For example, 19830905132800 and 830905132800 are interpreted as '1983-09-05 13:28:00'.

XSLT stylesheets must be well-formed XML. Since " " is not one of the five predefined XML entities, it cannot be directly included in the stylesheet. So coming back to your solution " " is a perfect replacement of " " you should use.

Example:

<xsl:value-of select="$txtFName"/>&#160;<xsl:value-of select="$txtLName"/>

This questions is already answered here. Just put height: 100% in both the div and the container td.

You are testing if the values of the variables error and Already are present in RepoOutput[RepoName.index(repo)]. If these variables don't exist then an undefined object is used.

Both of your if and elif tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].

I think you wanted to test if certain strings are in the value instead:

{% if "error" in RepoOutput[RepoName.index(repo)] %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
    <td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>

Other corrections I made:

• Used {% elif ... %} instead of {$ elif ... %}.
• moved the </tr> tag out of the if conditional structure, it needs to be there always.
• put quotes around the id attribute

Note that most likely you want to use a class attribute instead here, not an id, the latter must have a value that must be unique across your HTML document.

Personally, I'd set the class value here and reduce the duplication a little:

{% if "Already" in RepoOutput[RepoName.index(repo)] %}
    {% set row_class = "good" %}
{% else %}
    {% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

Use this code is whork :

if (!preg_match('#^http(s)?://#', $url)) {
         $url = 'http://' . $url;
}
$urlParts = parse_url($url);
$url = preg_replace('/^www\./', '', $urlParts['host']);

find location -ctime time_period

Examples of time_period:

• More than 30 days ago: -ctime +30

• Less than 30 days ago: -ctime -30

• Exactly 30 days ago: -ctime 30

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)
    end
end)

I understand your problem boils down to how to call a SOAP (JAX-WS) web service from Java and get its returning object. In that case, you have two possible approaches:

1. Generate the Java classes through wsimport and use them; or
2. Create a SOAP client that:
   1. Serializes the service's parameters to XML;
   2. Calls the web method through HTTP manipulation; and
   3. Parse the returning XML response back into an object.

About the first approach (using wsimport):

I see you already have the services' (entities or other) business classes, and it's a fact that the wsimport generates a whole new set of classes (that are somehow duplicates of the classes you already have).

I'm afraid, though, in this scenario, you can only either:

• Adapt (edit) the wsimport generated code to make it use your business classes (this is difficult and somehow not worth it - bear in mind everytime the WSDL changes, you'll have to regenerate and readapt the code); or
• Give up and use the wsimport generated classes. (In this solution, you business code could "use" the generated classes as a service from another architectural layer.)

About the second approach (create your custom SOAP client):

In order to implement the second approach, you'll have to:

1. Make the call:
   • Use the SAAJ (SOAP with Attachments API for Java) framework (see below, it's shipped with Java SE 1.6 or above) to make the calls; or
   • You can also do it through java.net.HttpUrlconnection (and some java.io handling).
2. Turn the objects into and back from XML:
   • Use an OXM (Object to XML Mapping) framework such as JAXB to serialize/deserialize the XML from/into objects
   • Or, if you must, manually create/parse the XML (this can be the best solution if the received object is only a little bit differente from the sent one).

Creating a SOAP client using classic java.net.HttpUrlConnection is not that hard (but not that simple either), and you can find in this link a very good starting code.

I recommend you use the SAAJ framework:

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.

About using JAXB for serializing/deserializing, it is very easy to find information about it. You can start here: http://www.mkyong.com/java/jaxb-hello-world-example/.

In getting started with require.js I ran into the issue and as a beginner the docs may as well been written in greek.

The issue I ran into was that most of the beginner examples use "anonymous defines" when you should be using a "string id".

anonymous defines

define(function() {
        return { helloWorld: function() { console.log('hello world!') } };
 })
    
  
define(function() {
        return { helloWorld2: function() { console.log('hello world again!') } };
 })

define with string id

define('moduleOne',function() {
    return { helloWorld: function() { console.log('hello world!') } };
})

 define('moduleTwo', function() {
      return { helloWorld2: function() { console.log('hello world again!') } };
})

When you use define with a string id then you will avoid this error when you try to use the modules like so:

require([ "moduleOne", "moduleTwo" ], function(moduleOne, moduleTwo) {
    moduleOne.helloWorld();
    moduleTwo.helloWorld2();
});

I always use this:

function validEmail($email){
    // First, we check that there's one @ symbol, and that the lengths are right
    if (!preg_match("/^[^@]{1,64}@[^@]{1,255}$/", $email)) {
        // Email invalid because wrong number of characters in one section, or wrong number of @ symbols.
        return false;
    }
    // Split it into sections to make life easier
    $email_array = explode("@", $email);
    $local_array = explode(".", $email_array[0]);
    for ($i = 0; $i < sizeof($local_array); $i++) {
        if (!preg_match("/^(([A-Za-z0-9!#$%&'*+\/=?^_`{|}~-][A-Za-z0-9!#$%&'*+\/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$/", $local_array[$i])) {
            return false;
        }
    }
    if (!preg_match("/^\[?[0-9\.]+\]?$/", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name
        $domain_array = explode(".", $email_array[1]);
        if (sizeof($domain_array) < 2) {
            return false; // Not enough parts to domain
        }
        for ($i = 0; $i < sizeof($domain_array); $i++) {
            if (!preg_match("/^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$/", $domain_array[$i])) {
                return false;
            }
        }
    }

    return true;
}

I've checked your source code and find to change to yellow you need to adds the yellow background color to : #left-padding, #right-padding, html, #hd, #main and #yui-main.

Hope it's what you wanted. See ya

@eeezyy's answer didn't work for me, although I'm using Spring Boot (2.0.4) and it may differ, but a variation here in 2018 works thus:

@Autowired
private HttpServletRequest request;

Some cases you might want to kill all the process running in a specific port. For example, if I am running a node app on 3000 port and I want to kill that and start a new one; then I found this command useful.

Find the process IDs running on TCP port 3000 and kill it

kill -9 `lsof -i TCP:3000 | awk '/LISTEN/{print $2}'`

As noted in the accepted answer - you can use the special { props.children } property. However - you can just pass a component as a prop as the title requests. I think this is cleaner sometimes as you might want to pass several components and have them render in different places. Here's the react docs with an example of how to do it:

https://reactjs.org/docs/composition-vs-inheritance.html

Make sure you are actually passing a component and not an object (this tripped me up initially).

The code is simply this:

const Parent = () => { 
  return (
    <Child  componentToPassDown={<SomeComp />}  />
  )
}

const Child = ({ componentToPassDown }) => { 
  return (
    <>
     {componentToPassDown}  
    </>
  )
}

You have to be specific about the columns you are selecting. If your user table had four columns id, name, username, opted_in you must select exactly those four columns from the query. The syntax looks like:

INSERT INTO user (id, name, username, opted_in)
  SELECT id, name, username, opted_in 
  FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id

However, there does not appear to be any reason to join against user_permission here, since none of the columns from that table would be inserted into user. In fact, this INSERT seems bound to fail with primary key uniqueness violations.

MySQL does not support inserts into multiple tables at the same time. You either need to perform two INSERT statements in your code, using the last insert id from the first query, or create an AFTER INSERT trigger on the primary table.

INSERT INTO user (name, username, email, opted_in) VALUES ('a','b','c',0);
/* Gets the id of the new row and inserts into the other table */
INSERT INTO user_permission (user_id, permission_id) VALUES (LAST_INSERT_ID(), 4)

Or using a trigger:

CREATE TRIGGER creat_perms AFTER INSERT ON `user`
FOR EACH ROW
BEGIN
  INSERT INTO user_permission (user_id, permission_id) VALUES (NEW.id, 4)
END

This is called string interpolation, and you do it like this:

"The #{animal} #{action} the #{second_animal}"

Important: it will only work when string is inside double quotes (" ").

Example of code that will not work as you expect:

'The #{animal} #{action} the #{second_animal}'

just call your function inside the events.

load:

$(document).ready(function(){  // or  $(window).load(function(){
    topInViewport($(mydivname));
});

resize:

$(window).resize(function () {
    topInViewport($(mydivname));
});

scroll:

$(window).scroll(function () {
    topInViewport($(mydivname));
});

or bind all event in one function

$(window).on("load scroll resize",function(e){

<select name="aa" onchange="report(this.value)"> 
  <option value="">Please select</option>
  <option value="daily">daily</option>
  <option value="monthly">monthly</option>
</select>

using

function report(period) {
  if (period=="") return; // please select - possibly you want something else here

  const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
  loadXMLDoc(report,'responseTag');
  document.getElementById('responseTag').style.visibility='visible';
  document.getElementById('list_report').style.visibility='hidden';
  document.getElementById('formTag').style.visibility='hidden'; 
} 

Unobtrusive version:

<select id="aa" name="aa"> 
  <option value="">Please select</option>
  <option value="daily">daily</option>
  <option value="monthly">monthly</option>
</select>

using

window.addEventListener("load",function() {
  document.getElementById("aa").addEventListener("change",function() {
    const period = this.value;
    if (period=="") return; // please select - possibly you want something else here

    const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
    loadXMLDoc(report,'responseTag');
    document.getElementById('responseTag').style.visibility='visible';
    document.getElementById('list_report').style.visibility='hidden';
    document.getElementById('formTag').style.visibility='hidden'; 
  }); 
});

jQuery version - same select with ID

$(function() {
  $("#aa").on("change",function() {
    const period = this.value;
    if (period=="") return; // please select - possibly you want something else here

    var report = "script/"+((period == "daily")?"d":"m")+"_report.php";
    loadXMLDoc(report,'responseTag');
    $('#responseTag').show();
    $('#list_report').hide();
    $('#formTag').hide(); 
  }); 
});

Simply add $title variable before require function

<?php
    $title = "Your title goes here";
    require("header.php");
  ?>

header.php

<title><?php echo $title; ?></title>

complete URL

If you want the complete URL e.g. http://website/basedirectory/workingdirectory/ use:

var location = window.location.href;
var directoryPath = location.substring(0, location.lastIndexOf("/")+1);

local path

If you want the local path without domain e.g. /basedirectory/workingdirectory/ use:

var location = window.location.pathname;
var directoryPath = location.substring(0, location.lastIndexOf("/")+1);

In case you don't need the slash at the end, remove the +1 after location.lastIndexOf("/")+1.

directory name

If you only want the current directory name, where the script is running in, e.g. workingdirectory use:

var location = window.location.pathname;
var path = location.substring(0, location.lastIndexOf("/"));
var directoryName = path.substring(path.lastIndexOf("/")+1);

Use isinstance:

if isinstance(e, list):

If you want to check that an object is a list or a tuple, pass several classes to isinstance:

if isinstance(e, (list, tuple)):

Swift 4.2 You can use condition like that:

let alert = UIAlertController(title: nil, message: nil, preferredStyle: UIDevice.current.userInterfaceIdiom == .pad ? .alert : .actionSheet)

Comparator<User> cmp = new Comparator<User>() {
    @Override
    public int compare(User user1, User user2) {
        return user1.date.compareTo(user2.date);
    }
};

Collections.max(list, cmp);

This question reminds of how to determine equality for two JavaScript objects. So, I would choose this general function

Compares JS objects:

function objectEquals(x, y) {
    // if both are function
    if (x instanceof Function) {
        if (y instanceof Function) {
            return x.toString() === y.toString();
        }
        return false;
    }
    if (x === null || x === undefined || y === null || y === undefined) { return x === y; }
    if (x === y || x.valueOf() === y.valueOf()) { return true; }

    // if one of them is date, they must had equal valueOf
    if (x instanceof Date) { return false; }
    if (y instanceof Date) { return false; }

    // if they are not function or strictly equal, they both need to be Objects
    if (!(x instanceof Object)) { return false; }
    if (!(y instanceof Object)) { return false; }

    var p = Object.keys(x);
    return Object.keys(y).every(function (i) { return p.indexOf(i) !== -1; }) ?
            p.every(function (i) { return objectEquals(x[i], y[i]); }) : false;
}

From New-style and classic classes:

Up to Python 2.1, old-style classes were the only flavour available to the user.

The concept of (old-style) class is unrelated to the concept of type: if x is an instance of an old-style class, then x.__class__ designates the class of x, but type(x) is always <type 'instance'>.

This reflects the fact that all old-style instances, independently of their class, are implemented with a single built-in type, called instance.

New-style classes were introduced in Python 2.2 to unify the concepts of class and type. A new-style class is simply a user-defined type, no more, no less.

If x is an instance of a new-style class, then type(x) is typically the same as x.__class__ (although this is not guaranteed – a new-style class instance is permitted to override the value returned for x.__class__).

The major motivation for introducing new-style classes is to provide a unified object model with a full meta-model.

It also has a number of immediate benefits, like the ability to subclass most built-in types, or the introduction of "descriptors", which enable computed properties.

For compatibility reasons, classes are still old-style by default.

New-style classes are created by specifying another new-style class (i.e. a type) as a parent class, or the "top-level type" object if no other parent is needed.

The behaviour of new-style classes differs from that of old-style classes in a number of important details in addition to what type returns.

Some of these changes are fundamental to the new object model, like the way special methods are invoked. Others are "fixes" that could not be implemented before for compatibility concerns, like the method resolution order in case of multiple inheritance.

Python 3 only has new-style classes.

No matter if you subclass from object or not, classes are new-style in Python 3.

The techniques outlined above describe your options pretty well. But what are the users seeing? I can't imagine how a basic conflict like this between you and whoever is responsible for the software can't end up in confusion and antagonism with the users.

I'd do everything I could to find some other way out of the impasse - because other people could easily see any change you make as escalating the problem.

EDIT:

I'll score my first "undelete" and admit to posting the above when this question first appeared. I of course chickened out when I saw that it was from JOEL SPOLSKY. But it looks like it landed somewhere near. Don't need votes, but I'll put it on the record.

IME, triggers are so seldom the right answer for anything other than fine-grained integrity constraints outside the realm of business rules.

For those facing a similar issue, I found that when 'simulating' a SET = NULL query, PHPMyAdmin would throw an error. It's a red herring.. just run the query and all will be well.

You need to actually run a webserver, and make the get request to a URI on that server, rather than making the get request to a file; e.g. change the line:

    $.get("C:/xampp/htdocs/webname/resources/templates/signup.php",

to read something like:

    $.get("http://localhost/resources/templates/signup.php",

and the initial request page needs to be made over http as well.

user.no_of_logins += 1
session.commit()

This didn't work for me.

sudo chmod -R 777 /path/to/your/file/or/directory

I used -f also.

sudo chmod -R -f 777 /path/to/your/file/or/directory

For MySQL:

SELECT lastname AS ln 
    FROM 
    (SELECT lastname, count(*) as Counter 
     FROM `students` 
     GROUP BY `lastname`) AS tbl WHERE Counter > 2

In my case the format set in Preferences/Database/NLS was [Date Format] = RRRR-MM-DD HH24:MI:SSXFF but in grid there were seen 8probably default format RRRR/MM/DD (even without time) The format has changed after changing the setting [Date Format] to: RRRR-MM-DD HH24:MI:SS (without 'XFF' at the end).

There were no errors, but format with xff at the end didn't work.

Note: in polish notation RRRR means YYYY

You're correct. As others said according to your comments, you probably did not initialize your ArrayList.

My point is different: you claimed that you're checking for duplicates and this is why you call the contains method. Try using HashSet. It should be more efficient - unless you need to keep the order of URLs for any reason.

Are those tags on 'http://www.mywebaddress.com'?

Bear in mind the linter will follow the og:url tag as this tag should point to the canonical URL of the piece of content - so if you have a page, e.g. 'http://mywebaddress.com/article1' with an og:url tag pointing to 'http://mywebaddress.com', Facebook will go there and read the tags there also.

Failing that, the most common reason i've seen for seemingly correct tags not being detected by the linter is user-agent detection returning different content to Facebook's crawler than the content you're seeing when you manually check

List is an interface, and you can not initialize an interface. Instantiate an implementing class instead.

Like:

List<String> abc = new ArrayList<String>();
List<String> xyz = new LinkedList<String>();

Here you go!

The first 30 seconds of this video shows how to use the global search feature of Phpmyadmin and it works. it will search every table for a string.

I'm inclined to agree with Qwertman that it's not currently possible to specify color for text in GitHub markdown, at least not through HTML.

GitHub does allow some HTML elements and attributes, but only certain ones (see their documentation about their HTML sanitization). They do allow p and div tags, as well as color attribute. However, when I tried using them in a markdown document on GitHub, it didn't work. I tried the following (among other variations), and they didn't work:

• <p style='color:red'>This is some red text.</p>
• <font color="red">This is some text!</font>
• These are <b style='color:red'>red words</b>.

As Qwertman suggested, if you really must use color you could do it in a README.html and refer them to it.

JQuery has actually two ways to set checked status for radio and checkboxes and it depends on whether you are using value attribute in HTML markup or not:

If they have value attribute:

$("[name=myRadio]").val(["myValue"]);

If they don't have value attribute:

$("#myRadio1").prop("checked", true);

More Details

In first case, we specify the entire radio group using name and tell JQuery to find radio to select using val function. The val function takes 1-element array and finds the radio with matching value, set its checked=true. Others with the same name would be deselected. If no radio with matching value found then all will be deselected. If there are multiple radios with same name and value then the last one would be selected and others would be deselected.

If you are not using value attribute for radio then you need to use unique ID to select particular radio in the group. In this case, you need to use prop function to set "checked" property. Many people don't use value attribute with checkboxes so #2 is more applicable for checkboxes then radios. Also note that as checkboxes don't form group when they have same name, you can do $("[name=myCheckBox").prop("checked", true); for checkboxes.

You can play with this code here: http://jsbin.com/OSULAtu/1/edit?html,output

If trigger("chosen:updated"); not working, use .trigger("liszt:updated"); of @Nhan Tran it is working fine.

If you need to remove white spaces at the end then here is a solution: https://www.geeksforgeeks.org/urlify-given-string-replace-spaces/

const stringQ1 = (string)=>{_x000D_
  //remove white space at the end _x000D_
  const arrString = string.split("")_x000D_
  for(let i = arrString.length -1 ; i>=0 ; i--){_x000D_
    let char = arrString[i];_x000D_
    _x000D_
    if(char.indexOf(" ") >=0){_x000D_
     arrString.splice(i,1)_x000D_
    }else{_x000D_
      break;_x000D_
    }_x000D_
  }_x000D_
_x000D_
  let start =0;_x000D_
  let end = arrString.length -1;_x000D_
  _x000D_
_x000D_
  //add %20_x000D_
  while(start < end){_x000D_
    if(arrString[start].indexOf(' ') >=0){_x000D_
      arrString[start] ="%20"_x000D_
      _x000D_
    }_x000D_
    _x000D_
    start++;_x000D_
  }_x000D_
  _x000D_
  return arrString.join('');_x000D_
}_x000D_
_x000D_
console.log(stringQ1("Mr John Smith   "))

If it helps, You can also create an alias in your .bashrc or .bash_profile.

function dsize()
{
    dir=$(pwd)
    if [ "$1" != "" ]; then
            dir=$1
    fi
    echo $(du -hs $dir)
}

This prints the size of the current directory or the directory you have passed as an argument.

Will be slightly neater using a CSS class instead of repeating inline styles.

CSS

input[type=submit] {
    position: absolute;
    left: -9999px;
}

HTML

<form ng-submit="myFunc()">
    <input type="text" ng-model="name" />
    <br />
    <input type="text" ng-model="email" />
    <input type="submit" />
</form>

I think this will help : In Controller get the list items and selected value

public ActionResult Edit(int id)
{
    ItemsStore item = itemStoreRepository.FindById(id);
    ViewBag.CategoryId = new SelectList(categoryRepository.Query().Get(), 
                                        "Id", "Name",item.CategoryId);

    // ViewBag to pass values to View and SelectList
    //(get list of items,valuefield,textfield,selectedValue)

    return View(item);
}

and in View

@Html.DropDownList("CategoryId",String.Empty)

If you application is a Windows GUI application then using the code below to do the waiting is not ideal as messages for your application will not be getting processing. To the user it will look like your application has hung.

WaitForSingleObject(&processInfo.hProcess, INFINITE)

Something like the untested code below might be better as it will keep processing the windows message queue and your application will remain responsive:

//-- wait for the process to finish
while (true)
{
  //-- see if the task has terminated
  DWORD dwExitCode = WaitForSingleObject(ProcessInfo.hProcess, 0);

  if (   (dwExitCode == WAIT_FAILED   )
      || (dwExitCode == WAIT_OBJECT_0 )
      || (dwExitCode == WAIT_ABANDONED) )
  {
    DWORD dwExitCode;

    //-- get the process exit code
    GetExitCodeProcess(ProcessInfo.hProcess, &dwExitCode);

    //-- the task has ended so close the handle
    CloseHandle(ProcessInfo.hThread);
    CloseHandle(ProcessInfo.hProcess);

    //-- save the exit code
    lExitCode = dwExitCode;

    return;
  }
  else
  {
    //-- see if there are any message that need to be processed
    while (PeekMessage(&message.msg, 0, 0, 0, PM_NOREMOVE))
    {
      if (message.msg.message == WM_QUIT)
      {
        return;
      }

      //-- process the message queue
      if (GetMessage(&message.msg, 0, 0, 0))
      {
        //-- process the message
        TranslateMessage(&pMessage->msg);
        DispatchMessage(&pMessage->msg);
      }
    }
  }
}

I had the same error and fixed it. It turned out to be a silly reason.

This was the culprit: <script src="app.js"/>

Fix: <script src="app.js"></script>

Make sure your script tag is ended properly!

You can also use git-copy.

Install it with Gem,

gem install git-copy

Then

git copy https://github.com/exampleuser/old-repository.git \
    https://github.com/exampleuser/new-repository.git

If you have or want to keep your elements as variables (jQuery objects), you can also loop over them:

var $class1 = $('.class1');
var $class2 = $('.class2');

$([$class1,$class2]).each(function() {
    $(this).on('click', function(e) {
        some_function();
    });
});

You can also set processData to true:

collection.fetch({ 
    data: { page: 1 },
    processData: true
});

Jquery will auto process data object into param string,

but in Backbone.sync function, Backbone turn the processData off because Backbone will use other method to process data in POST,UPDATE...

in Backbone source:

if (params.type !== 'GET' && !Backbone.emulateJSON) {
    params.processData = false;
}

There is no built-in way. You can have MyClass implement the IClonable interface (but it is sort of deprecated) or just write your own Copy/Clone method. In either case you will have to write some code.

For big objects you could consider Serialization + Deserialization (through a MemoryStream), just to reuse existing code.

Whatever the method, think carefully about what "a copy" means exactly. How deep should it go, are there Id fields to be excepted etc.

Make sure you type the command from the "App" Directory
