You don't need to do special things in the form. You just build the comment correctly in the show action:

class ArticlesController < ActionController::Base
  ....
  def show
    @article = Article.find(params[:id])
    @new_comment = @article.comments.build
  end
  ....
end

and then make a form for it in the article view:

<% form_for @new_comment do |f| %>
   <%= f.text_area :text %>
   <%= f.submit "Post Comment" %>
<% end %>

by default, this comment will go to the create action of CommentsController, which you will then probably want to put redirect :back into so you're routed back to the Article page.

The information you want can be found by running

mysql --help

or

mysqld --help --verbose

I tried this :

    mysql --help | grep Default -A 1

And the output:

                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash

                      (Defaults to on; use --skip-line-numbers to disable.)
  -L, --skip-line-numbers

                      (Defaults to on; use --skip-column-names to disable.)
  -N, --skip-column-names 
--
                      (Defaults to on; use --skip-reconnect to disable.)
  -s, --silent        Be more silent. Print results with a tab as separator,

  --default-auth=name Default authentication client-side plugin to use.
  --binary-mode       By default, ASCII '\0' is disallowed and '\r\n' is
--
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf 

to read first line using bash, use read statement. eg

read -r firstline<file

firstline will be your variable (No need to assign to another)

For me, dataBinding { enabled true } was enabled in gradle, removing this helped me

Give this a shot:

has_many :jobs, foreign_key: "user_id", class_name: "Task"

Note, that :as is used for polymorphic associations.

You don't need an initializer, unless you're dynamically loading a different image each time. I think doing as much as possible in fxml is more organized. Here is an fxml file that will do what you need.

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import javafx.scene.image.*?>
<?import javafx.scene.layout.*?>

<AnchorPane
    xmlns:fx="http://javafx.co/fxml/1"
    xmlns="http://javafx.com/javafx/2.2"
    fx:controller="application.SampleController"
    prefHeight="316.0"
    prefWidth="321.0"
    >
    <children>
        <ImageView
                fx:id="imageView"
                fitHeight="150.0"
                fitWidth="200.0"
                layoutX="61.0"
                layoutY="83.0"
                pickOnBounds="true"
                preserveRatio="true"
            >
            <image>
                <Image
                    url="src/Box13.jpg"
                    backgroundLoading="true"
                    />
            </image>
        </ImageView>
    </children>
</AnchorPane>

Specifying the backgroundLoading property in the Image tag is optional, it defaults to false. It's best to set backgroundLoading true when it takes a moment or longer to load the image, that way a placeholder will be used until the image loads, and the program wont freeze while loading.

To remove specific key and element from hashmap use

hashmap.remove(key)

full source code is like

import java.util.HashMap;
public class RemoveMapping {
     public static void main(String a[]){
        HashMap hashMap = new HashMap();
        hashMap.put(1, "One");
        hashMap.put(2, "Two");
        hashMap.put(3, "Three");
        System.out.println("Original HashMap : "+hashMap);
        hashMap.remove(3);   
        System.out.println("Changed HashMap : "+hashMap);        
    }
}

You need to call finish() from the UI thread, not a background thread. The way to do this is to declare a Handler and ask the Handler to run a Runnable on the UI thread. For example:

public class LoadingScreen extends Activity{
    private LoadingScreen loadingScreen;
    Intent i = new Intent(this, HomeScreen.class);
    Handler handler;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        handler = new Handler();
        setContentView(R.layout.loading);

        CountDownTimer timer = new CountDownTimer(10000, 1000) //10seceonds Timer
        {
             @Override
             public void onTick(long l) 
             {

             }

             @Override
             public void onFinish() 
             {
                 handler.post(new Runnable() {
                     public void run() {
                         loadingScreen.finishActivity(0);
                         startActivity(i);
                     }
                 });
             };
        }.start();
    }
}

The LTrim function to remove leading spaces and the RTrim function to remove trailing spaces from a string variable. It uses the Trim function to remove both types of spaces and means before and after spaces of string.

try to use unix4j. it s about a library in java to run linux command. for instance if you got a command like: cat test.txt | grep "Tuesday" | sed "s/kilogram/kg/g" | sort in this program will become: Unix4j.cat("test.txt").grep("Tuesday").sed("s/kilogram/kg/g").sort();

Simple:

  public static String decToHex(int dec)
  {
        return Integer.toHexString(dec);
  }

As mentioned here: Java Convert integer to hex integer

public static void main(String[] args) throws IOException {
    String filePath = "/Users/myXml/VH181.xml";
    File xmlFile = new File(filePath);
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder;
    try {
        dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(xmlFile);
        doc.getDocumentElement().normalize();
        printElement(doc);
        System.out.println("XML file updated successfully");
    } catch (SAXException | ParserConfigurationException e1) {
        e1.printStackTrace();
    }
}
private static void printElement(Document someNode) {
    NodeList nodeList = someNode.getElementsByTagName("choiceInteraction");
    for(int z=0,size= nodeList.getLength();z<size; z++) {
            String Value = nodeList.item(z).getAttributes().getNamedItem("id").getNodeValue();
            System.out.println("Choice Interaction Id:"+Value);
        }
    }

we Can try this code using method

A simpler way would be to do:

ObjectA.Verify(
    a => a.Execute(
        It.Is<Params>(p => p.Id == 7)
    )
);

find() and closest() seems slightly slower than:

$(this).parent().attr("id");

For Laravel version >=5.1

storage_path()

The storage_path function returns the fully qualified path to the storage directory:

$path = storage_path();

You may also use the storage_path function to generate a fully qualified path to a given file relative to the storage directory:

$app_path = storage_path('app');
$file_path = storage_path('app/file.txt');

From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning

the following

Excessive GC Time and OutOfMemoryError

The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.

The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).

in conjunction with a passage further down

One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,

java -Dsun.rmi.dgc.client.gcInterval=3600000

-Dsun.rmi.dgc.server.gcInterval=3600000 specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.

Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.

Of course, other interpretations are possible.

Kotlin DSL: add to your build.gradle.kts

}

In the old days, you would use frames to achieve this. There are several reasons why this approach is not so good. See Reece's response to Why are HTML frames bad?. See also Jakob Nielson's Why Frames Suck (Most of the Time).

A somewhat newer approach is to use inline frames. This has pluses and minuses as well: Are iframes considered 'bad practice'?

An even better approach is to use fixed positioning. By placing the navigation content (e.g. the favorites links in your example) in a block element (like a div) then applying position:fixed to that element and setting the left, top and bottom properties like this:

#myNav {
    position: fixed;
    left: 0px;
    top: 0px;
    bottom: 0px;
    width: 200px;
}

... you will achieve a vertical column down the left side of the page that will not move when the user scrolls the page.

The rest of the content on the page will not "feel" the presence of this nav element, so it must take into account the 200px of space it occupies. You can do this by placing the rest for the content in another div and setting margin-left:200px;.

MongoDB has a simple web based administrative port at 28017 by default.

There is no HTTP access at the default port of 27017 (which is what the error message is trying to suggest). The default port is used for native driver access, not HTTP traffic.

To access MongoDB, you'll need to use a driver like the MongoDB native driver for NodeJS. You won't "POST" to MongoDB directly (but you might create a RESTful API using express which uses the native drivers). Instead, you'll use a wrapper library that makes accessing MongoDB convenient. You might also consider using Mongoose (which uses the native driver) which adds an ORM-like model for MongoDB in NodeJS.

If you can't get to the web interface, it may be disabled. Normally, I wouldn't expect that you'd need it for doing development unless you're checking logs and such.

Use xpath more directly for both performance and clarity.

time_path <- "//start-valid-time"
temp_path <- "//temperature[@type='hourly']/value"

df <- data.frame(
    latitude=data[["number(//point/@latitude)"]],
    longitude=data[["number(//point/@longitude)"]],
    start_valid_time=sapply(data[time_path], xmlValue),
    hourly_temperature=as.integer(sapply(data[temp_path], as, "integer"))

leading to

> head(df, 2)
  latitude longitude          start_valid_time hourly_temperature
1    29.81    -82.42 2014-02-14T18:00:00-05:00                 60
2    29.81    -82.42 2014-02-14T19:00:00-05:00                 55

first, you have to create a handler.

var specialElementHandlers = {
    '#editor': function(element, renderer){
        return true;
    }
};

then write this code in click event:

doc.fromHTML($('body').get(0), 15, 15, {
    'width': 170, 
    'elementHandlers': specialElementHandlers
        });

var pdfOutput = doc.output();
            console.log(">>>"+pdfOutput );

assuming you've already declared doc variable. And Then you have save this pdf file using File-Plugin.

Jack M. is right. Do it this way:

>>> class City:
...     def __init__(self, city=None):
...         self.city = city
...     def __repr__(self):
...         if self.city:  return self.city
...         return ''
...
>>> c = City('Berlin')
>>> print c
Berlin
>>> c = City()
>>> print c

>>>

Default values cannot be supplied for parameters that are not declared 'optional'

 Function GetFindBooks(id As Integer, ByVal pid As Integer, Optional sort As String = "DESC", Optional limit As Integer = 99)

In your WebApiConfig

 config.Routes.MapHttpRoute( _
          name:="books", _
          routeTemplate:="api/{controller}/{action}/{id}/{pid}/{sort}/{limit}", _
          defaults:=New With {.id = RouteParameter.Optional, .pid = RouteParameter.Optional, .sort = UrlParameter.Optional, .limit = UrlParameter.Optional} _
      )

Yes you can solve this error by changing the port number of glassfish because the WAMP SERVER or ORACLE database software uses a port number 8080, so there is a conflict of port number.

1)open a path like C:\GlassFish_Server\glassfish\domains\domain1\config\domain.xml.

2)find out the 8080 port number with the help of ctrl+F. You will get the following code...

<network-listener protocol="http-listener-1" port="8080" name="http-listener-1" thread-pool="http-thread-pool" transport="tcp">

3) Change that port number from 8080 to 9090 or 1234 or whatever you like..

4) Save it. Open a Netbeans IDE goto the glassfish server .

5) Right click on the server -> select refresh option.

6) to check the port no. which is given by u just right click on the server-> property.

7) Start the Glassfish server . Yehhh the error is gone...

In addition to the commonly known five characters [<, >, &, ", and '], I would also escape the vertical tab character (0x0B). It is valid UTF-8, but not valid XML 1.0, and even many libraries (including the highly portable (ANSI C) library libxml2) miss it and silently output invalid XML.

Well, the dead-simple way to do it is to make a list of all the numbers you're interested in:

numbers = ["zero", "one", "two", "three", "four", "five", ... 
           "ninety-eight", "ninety-nine"]

(The ... indicates where you'd type the text representations of other numbers. No, Python isn't going to magically fill that in for you, you'd have to type all of them to use that technique.)

And then to print the number, just print numbers[i]. Easy peasy.

Of course, that list is a lot of typing, so you might wonder about an easy way to generate it. English unfortunately has a lot of irregularities so you'd have to manually put in the first twenty (0-19), but you can use regularities to generate the rest up to 99. (You can also generate some of the teens, but only some of them, so it seems easiest to just type them in.)

numbers = "zero one two three four five six seven eight nine".split()
numbers.extend("ten eleven twelve thirteen fourteen fifteen sixteen".split())
numbers.extend("seventeen eighteen nineteen".split())
numbers.extend(tens if ones == "zero" else (tens + "-" + ones) 
    for tens in "twenty thirty forty fifty sixty seventy eighty ninety".split()
    for ones in numbers[0:10])

print numbers[42]  # "forty-two"

Another approach is to write a function that puts together the correct string each time. Again you'll have to hard-code the first twenty numbers, but after that you can easily generate them from scratch as needed. This uses a little less memory (a lot less once you start working with larger numbers).

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

You can use display: table-cell in order to render the div as a table cell and then use vertical-align like you would do in a normal table cell.

#AlertDiv {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

%d seems to be the norm for printing integers, I never figured out why, they behave identically.

Here is another solution using css transform (for performance purposes on mobiles, see answer of @mate64 ) without having to use animations and keyframes.

I extended ??s???? K's answer to make the code full and workable. So, when you finish filling your 'all_thumbs' list, you should put its content one by one into the bundle and then into the intent:

Bundle bundle = new Bundle();

for (int i = 0; i<all_thumbs.size(); i++)
bundle.putSerializable("extras"+i, all_thumbs.get(i));

intent.putExtras(bundle);

In order to get the extras from the intent, you need:

Bundle bundle = new Bundle();
List<Thumbnail> thumbnailObjects = new ArrayList<Thumbnail>();

// collect your Thumbnail objects
for (String key : bundle.keySet()) {
thumbnailObjects.add((Thumbnail) bundle.getSerializable(key));
}

// for example, in order to get a value of the 3-rd object you need to:
String label = thumbnailObjects.get(2).get_label();

Advantage of Serializable is its simplicity. However, I would recommend you to consider using Parcelable method when you need transfer many data, because Parcelable is specifically designed for Android and it is more efficient than Serializable. You can create Parcelable class using:

1. an online tool - parcelabler
2. a plugin for Android Studion - Android Parcelable code generator

You can do it with simple if statement

To check for float

if type(a)==type(1.1)

To check for integer type

if type(a)==type(1)

Despite the fact that this is a very old question and probably many of the beforementioned ideas solved many problems, I still want to share the solution with the community that fixed my problem.

I found that the problem was a function called "hasItem" which I was using to check whether or not a JSON-Array contains a specific item. In my case I checked for a value of type Long.

And this led to the problem.

Somehow, the Matchers have problems with values of type Long. (I do not use JUnit or Rest-Assured so much so idk. exactly why, but I guess that the returned JSON-data does just contain Integers.)

So what I did to actually fix the problem was the following. Instead of using:

long ID = ...;

...
.then().assertThat()
  .body("myArray", hasItem(ID));

you just have to cast to Integer. So the working code looked like this:

long ID = ...;

...
.then().assertThat()
  .body("myArray", hasItem((int) ID));

That's probably not the best solution, but I just wanted to mention that the exception can also be thrown because of wrong/unknown data types.

When you want a flex item to occupy an entire row, set it to width: 100% or flex-basis: 100%, and enable wrap on the container.

The item now consumes all available space. Siblings are forced on to other rows.

.parent {
  display: flex;
  flex-wrap: wrap;
}

#range, #text {
  flex: 1;
}

.error {
  flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
  border: 1px dashed black;
}

<div class="parent">
  <input type="range" id="range">
  <input type="text" id="text">
  <label class="error">Error message (takes full width)</label>
</div>

More info: The initial value of the flex-wrap property is nowrap, which means that all items will line up in a row. MDN

usually in maven we have two types of builds 1)Snapshot builds 2)Release builds

1. snapshot builds:SNAPSHOT is the special version that indicate current deployment copy not like a regular version, maven checks the version for every build in the remote repository so the snapshot builds are nothing but development builds.

2. Release builds:Release means removing the SNAPSHOT at the version for the build, these are the regular build versions.

This is one of the reasons why C++ introduced the new cast style, which includes static_cast and reinterpret_cast

There's two things you can mean by saying conversion from signed to unsigned, you might mean that you wish the unsigned variable to contain the value of the signed variable modulo the maximum value of your unsigned type + 1. That is if your signed char has a value of -128 then CHAR_MAX+1 is added for a value of 128 and if it has a value of -1, then CHAR_MAX+1 is added for a value of 255, this is what is done by static_cast. On the other hand you might mean to interpret the bit value of the memory referenced by some variable to be interpreted as an unsigned byte, regardless of the signed integer representation used on the system, i.e. if it has bit value 0b10000000 it should evaluate to value 128, and 255 for bit value 0b11111111, this is accomplished with reinterpret_cast.

Now, for the two's complement representation this happens to be exactly the same thing, since -128 is represented as 0b10000000 and -1 is represented as 0b11111111 and likewise for all in between. However other computers (usually older architectures) may use different signed representation such as sign-and-magnitude or ones' complement. In ones' complement the 0b10000000 bitvalue would not be -128, but -127, so a static cast to unsigned char would make this 129, while a reinterpret_cast would make this 128. Additionally in ones' complement the 0b11111111 bitvalue would not be -1, but -0, (yes this value exists in ones' complement,) and would be converted to a value of 0 with a static_cast, but a value of 255 with a reinterpret_cast. Note that in the case of ones' complement the unsigned value of 128 can actually not be represented in a signed char, since it ranges from -127 to 127, due to the -0 value.

I have to say that the vast majority of computers will be using two's complement making the whole issue moot for just about anywhere your code will ever run. You will likely only ever see systems with anything other than two's complement in very old architectures, think '60s timeframe.

The syntax boils down to the following:

signed char x = -100;
unsigned char y;

y = (unsigned char)x;                    // C static
y = *(unsigned char*)(&x);               // C reinterpret
y = static_cast<unsigned char>(x);       // C++ static
y = reinterpret_cast<unsigned char&>(x); // C++ reinterpret

To do this in a nice C++ way with arrays:

jbyte memory_buffer[nr_pixels];
unsigned char* pixels = reinterpret_cast<unsigned char*>(memory_buffer);

or the C way:

unsigned char* pixels = (unsigned char*)memory_buffer;

Html.RenderPartial() is a void method - you can check whether a method is a void method by placing your mouse over the call to RenderPartial in your code and you will see the text (extension) void HtmlHelper.RenderPartial...

Void methods require a semicolon at the end of the calling code.

In the Webforms view engine you would have encased your Html.RenderPartial() call within the bee stings <% %>

like so

<% Html.RenderPartial("Path/to/my/partial/view"); %>

when you are using the Razor view engine the equivalent is

@{Html.RenderPartial("Path/to/my/partial/view");}

I faced the same problem and try to solve, but unfortunately it wouldn't work anymore ! If you are facing the same problem and can't find the solution, it may help you.

If you configure jquery/jquery-ui globally in webpack, you need to import autocomplete like this

import { autocomplete } from 'webpack-jquery-ui';

And you must include jquery-ui.css in the head section of html, i don't understand why its not working without it!

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

Hope your problem will be solved.

And make sure you include/install the following three

1. jquery-ui-css
2. jquery-ui
3. jquery

As I am reluctant to install new programs into my machine, this PowerShell script (from Hey, Scripting Guy! Blog) helped me solve my problem. I only modified the path to suit my case:

$fso = Get-ChildItem -Recurse -path F:\songs
$fsoBU = Get-ChildItem -Recurse -path D:\songs
Compare-Object -ReferenceObject $fso -DifferenceObject $fsoBU

What a BUG ! Here is another workaround...

public void forceRefresh() {
  final TableColumn< Prospect, ? > firstColumn = view.getColumns().get( 0 );
  firstColumn.setVisible( false );
  new Timer().schedule( new TimerTask() { @Override public void run() {
     Platform.runLater( new Runnable() { @Override public void run() {
        firstColumn.setVisible( true  ); }});
     }}, 100 );
}

I've done a SSCCE to show the bug. I encourage everyone to fix it by another more elegant way because my workaround is very ugly!

Use git branch -a (both local and remote branches) or git branch -r (only remote branches) to see all the remotes and their branches. You can then do a git checkout -t remotes/repo/branch to the remote and create a local branch.

There is also a git-ls-remote command to see all the refs and tags for that remote.

I use LuaSocket to get more precision.

require "socket"
print("Milliseconds: " .. socket.gettime()*1000)

This adds a dependency of course, but works fine for personal use (in benchmarking scripts for example).

ES6 supports binary numeric literals for integers, so if the binary string is immutable, as in the example code in the question, one could just type it in as it is with the prefix 0b or 0B:

var binary = 0b1101000; // code for 104
console.log(binary); // prints 104

From http://codecorner.galanter.net/2014/09/02/reenable-showmodaldialog-in-chrome/

It's deprecated by design. You can re-enable showModalDialog support, but only temporarily – until May of 2015. Use this time to create alternative solutions.

Here’s how to do it in Chrome for Windows. Open Registry Editor (regedit) and create following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\EnableDeprecatedWebPlatformFeatures

Under the EnableDeprecatedWebPlatformFeatures key create a string value with name 1 and value of ShowModalDialog_EffectiveUntil20150430. To verify that the policy is enabled, visit chrome://policy URL.

1. Download Chrome ADM templates from http://www.chromium.org/administrators/policy-templates
2. Extract and import policy relevant to your locale (e.g. windows\adm\en-US\chrome.adm. You can import either via gpedit.mscor using these utilities on Home editions of windows: http://blogs.technet.com/b/fdcc/archive/2008/05/07/lgpo-utilities.aspx)
3. Under “Adminstrative Templates” locate Google Chrome template and enable “Enable Deprecated Web Platform Feautes”.
4. Open the feature and add “ShowModalDialog_EffectiveUntil20150430" key.

In your Case you can write the following jquery code:

$(document).ready(function(){

   $('.staff_on_site').click(function(){

     var rBtnVal = $(this).val();

     if(rBtnVal == "yes"){
         $("#no_of_staff").attr("readonly", false); 
     }
     else{ 
         $("#no_of_staff").attr("readonly", true); 
     }
   });
});

Here is the Fiddle: http://jsfiddle.net/P4QWx/3/

Currently you are clearing the name array, you need to call the array then the index you want to unset within the array:

$ar[0]==2
$ar[1]==7
$ar[2]==9

unset ($ar[2])

Two ways of unsetting values within an array:

<?php
# remove by key:
function array_remove_key ()
{
  $args  = func_get_args();
  return array_diff_key($args[0],array_flip(array_slice($args,1)));
}
# remove by value:
function array_remove_value ()
{
  $args = func_get_args();
  return array_diff($args[0],array_slice($args,1));
}

$fruit_inventory = array(
  'apples' => 52,
  'bananas' => 78,
  'peaches' => 'out of season',
  'pears' => 'out of season',
  'oranges' => 'no longer sold',
  'carrots' => 15,
  'beets' => 15,
);

echo "<pre>Original Array:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';

# For example, beets and carrots are not fruits...
$fruit_inventory = array_remove_key($fruit_inventory,
                                    "beets",
                                    "carrots");
echo "<pre>Array after key removal:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';

# Let's also remove 'out of season' and 'no longer sold' fruit...
$fruit_inventory = array_remove_value($fruit_inventory,
                                      "out of season",
                                      "no longer sold");
echo "<pre>Array after value removal:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';
?> 

So, unset has no effect to internal array counter!!!

Okay a lot has been said, but just in case nothing of the previous answers work, you can try;

https://www.scipy.org/install.html

According to them;

For most users, especially on Windows, the easiest way to install the packages of the SciPy stack is to download one of these Python distributions, which include all the key packages:

• Anacond: A free distribution for the SciPy stack. Supports Linux, Windows and Mac.
• Enthought Canopy: The free and commercial versions include the core SciPy stack packages. Supports Linux, Windows and Mac.
• Python(x,y) A free distribution including the SciPy stack, based around the Spyder IDE. Windows only.
• WinPython: A free distribution including the SciPy stack. Windows only.
• Pyzo: A free distribution based on Anaconda and the IEP interactive development environment. Supports Linux, Windows and Mac.

Still for me, Anaconda did solve this problem. Do remember to check the bit (32/64 bit) version before downloading and re-adjust your compiler to the Python implementation installed with the Python distribution you are installing.

When you type integer numbers to JtextField1 after key release it will go to inside try , for any other character it will throw NumberFormatException. If you set empty string to jTextField1 inside the catch so the user cannot type any other keys except positive numbers because JTextField1 will be cleared for each bad attempt.

 //Fields 
int x;
JTextField jTextField1;

 //Gui Code Here

private void jTextField1KeyReleased(java.awt.event.KeyEvent evt) {                                        
    try {
        x = Integer.parseInt(jTextField1.getText());
    } catch (NumberFormatException nfe) {
        jTextField1.setText("");
    }
}   

Use DATE() function:

select * from follow_queue group by DATE(follow_date)

Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.

Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:

/link/mybackend/?field1=value1&field2=value2&field3=value3

and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET.

So your urlconf would be:

url(r'^link/(?P<backend>\w+?)/$', my_function)

and the view would look like:

def my_function(request, backend):
   data = request.GET

and the reverse would be (after importing urllib):

return "%s?%s" % (redirect('my_function', args=(backend,)),
                  urllib.urlencode(form.cleaned_data))

Edited after comment

The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.

If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.

That said, if all you want to do is store the data, then just put it in the session:

request.session['temp_data'] = form.cleaned_data

I also favor the RegEx solution. The code will be much cleaner. I would hesitate to use toLowerCase() in situations where I knew the strings were going to be large, since strings are immutable and would have to be copied. Also, the matches() solution might be confusing because it takes a regular expression as an argument (searching for "Need$le" cold be problematic).

Building on some of the above examples:

public boolean containsIgnoreCase( String haystack, String needle ) {
  if(needle.equals(""))
    return true;
  if(haystack == null || needle == null || haystack .equals(""))
    return false; 

  Pattern p = Pattern.compile(needle,Pattern.CASE_INSENSITIVE+Pattern.LITERAL);
  Matcher m = p.matcher(haystack);
  return m.find();
}

example call: 

String needle = "Need$le";
String haystack = "This is a haystack that might have a need$le in it.";
if( containsIgnoreCase( haystack, needle) ) {
  System.out.println( "Found " + needle + " within " + haystack + "." );
}

(Note: you might want to handle NULL and empty strings differently depending on your needs. I think they way I have it is closer to the Java spec for strings.)

Speed critical solutions could include iterating through the haystack character by character looking for the first character of the needle. When the first character is matched (case insenstively), begin iterating through the needle character by character, looking for the corresponding character in the haystack and returning "true" if all characters get matched. If a non-matched character is encountered, resume iteration through the haystack at the next character, returning "false" if a position > haystack.length() - needle.length() is reached.

Using document.body.innerHTML = ''; does work! Just saying, if using HTML (DOM or on function) you can use
document.writeln(''); but only onClick or onDoubleClick :)

You have to load the db library first. In autoload.php add :

$autoload['libraries'] = array('database');

Also, try renaming User model class for "User_model".

Simple extension for UIApplication in Swift (cares even about moreNavigationController within UITabBarController on iPhone):

extension UIApplication {
    class func topViewController(base: UIViewController? = UIApplication.sharedApplication().keyWindow?.rootViewController) -> UIViewController? {

        if let nav = base as? UINavigationController {
            return topViewController(base: nav.visibleViewController)
        }

        if let tab = base as? UITabBarController {
            let moreNavigationController = tab.moreNavigationController

            if let top = moreNavigationController.topViewController where top.view.window != nil {
                return topViewController(top)
            } else if let selected = tab.selectedViewController {
                return topViewController(selected)
            }
        }

        if let presented = base?.presentedViewController {
            return topViewController(base: presented)
        }

        return base
    }
}

Simple usage:

    if let rootViewController = UIApplication.topViewController() {
        //do sth with root view controller
    }

Works perfect:-)

UPDATE for clean code:

extension UIViewController {
    var top: UIViewController? {
        if let controller = self as? UINavigationController {
            return controller.topViewController?.top
        }
        if let controller = self as? UISplitViewController {
            return controller.viewControllers.last?.top
        }
        if let controller = self as? UITabBarController {
            return controller.selectedViewController?.top
        }
        if let controller = presentedViewController {
            return controller.top
        }
        return self
    }
}

I. In your build.gradle add latest appcompat library, at the time 24.2.1

dependencies {  
    compile 'com.android.support:appcompat-v7:X.X.X' 
    // where X.X.X version
}

II. Make your activity extend android.support.v7.app.AppCompatActivity and implement the DatePickerDialog.OnDateSetListener interface.

public class MainActivity extends AppCompatActivity  
    implements DatePickerDialog.OnDateSetListener {

III. Create your DatePickerDialog setting a context, the implementation of the listener and the start year, month and day of the date picker.

DatePickerDialog datePickerDialog = new DatePickerDialog(  
    context, MainActivity.this, startYear, starthMonth, startDay);

IV. Show your dialog on the click event listener of your button

((Button) findViewById(R.id.myButton))
    .setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        datePickerDialog.show();
    }
});

As hinted at by this post Error in chrome: Content-Type is not allowed by Access-Control-Allow-Headers just add the additional header to your web.config like so...

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
  </customHeaders>
</httpProtocol>

I had the same problem and the solution was to encapsulate the json inside this function

jsonp(

.... your json ...

)

How about:

var selector = "*"
$(selector).click(function() {
    alert(selector);
});

I don't believe jQuery store the selector text that was used. After all, how would that work if you did something like this:

$("div").find("a").click(function() {
    // what would expect the 'selector' to be here?
});

Use desc and multiply by -1 if necessary. Example for ascending int ordering with nulls last:

select * 
from
(select null v union all select 1 v union all select 2 v) t
order by -t.v desc

I'd rather use static widths and if you'd like your page to resize depending on screen size, you can have a look at media queries.

Or, you can set a min-width on elements like header, navigation, content etc.

Very easy trick is using a CSS calc formula. All modern browsers, IE9, wide range of mobile browsers should support this.

<div style='white-space:nowrap'>
  <span style='display:inline-block;width:80px;font-weight:bold'>
    <label for='field1'>Field1</label>
  </span>
  <input id='field1' name='field1' type='text' value='Some text' size='30' style='width:calc(100% - 80px)' />
</div>

The following should suffice:

[^ ]

If you want to expand that to anything but white-space (line breaks, tabs, spaces, hard spaces):

[^\s]

or

\S  # Note this is a CAPITAL 'S'!

The BlackBerry browser and Safari for iOS (iPhone/iPod/iPad) automatically detect phone numbers and email addresses and convert them to links. If you don’t want this feature, you should use the following meta tags.

For Safari:

<meta name="format-detection" content="telephone=no">

For BlackBerry:

<meta http-equiv="x-rim-auto-match" content="none">

After much searching a way to show a progress bar just to make the most elegant charging could not find any way that would serve my purpose. Check the actual status of the request showed demaziado complex and sometimes snippets not then worked created a very simple way but it gives me the experience seeking (or almost), follows the code:

$.ajax({
    type : 'GET',
    url : url,
    dataType: 'html',
    timeout: 10000,
    beforeSend: function(){
        $('.my-box').html('<div class="progress"><div class="progress-bar progress-bar-success progress-bar-striped active" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 0%;"></div></div>');
        $('.progress-bar').animate({width: "30%"}, 100);
    },
    success: function(data){  
        if(data == 'Unauthorized.'){

        }
    },
    error: function(request, status, err) {
        alert((status == "timeout") ? "Timeout" : "error: " + request + status + err);
    }
});

sys.dm_tran_locks contains the locking information of the sessions

If you want to know a specific table is locked or not, you can use the following query

SELECT 
 * 
from 
 sys.dm_tran_locks 
where 
  resource_associated_entity_id = object_id('schemaname.tablename')

if you are interested in finding both login name of the user and the query being run

SELECT
 DB_NAME(resource_database_id)
 , s.original_login_name
 , s.status
 , s.program_name
 , s.host_name
 , (select text from sys.dm_exec_sql_text(exrequests.sql_handle))
 ,*
from
  sys.dm_tran_locks dbl
     JOIN sys.dm_exec_sessions s ON dbl.request_session_id = s.session_id
  INNER JOIN  sys.dm_exec_requests exrequests on dbl.request_session_id = exrequests.session_id
where
 DB_NAME(dbl.resource_database_id) = 'dbname'

I fixed all my asp.net problems simply by creating a new user called IUSER with a password and added it the Network Service and User Groups. Then create all your virtual sites and applications set authentication to IUSER with its password.. set high level file access to include IUSER and BAM it fixed at least 3-4 issues including this one..

Dave

You did not do anything wrong here, it will any other thing that is overriding the image size.

You can check this working fiddle.

And in this fiddle I have alter the image size using %, and it is working.

Also try using this code:

<img src="image.jpg" style="width: 50%; height: 50%"/>?

Here is the example fiddle.

I find this more idiomatic:

def proc = "ls foo.txt doesnotexist.txt".execute()
assert proc.in.text == "foo.txt\n"
assert proc.err.text == "ls: doesnotexist.txt: No such file or directory\n"

As another post mentions, these are blocking calls, but since we want to work with the output, this may be necessary.

First you need to use this command

npm config set registry https://registry.your-registry.npme.io/

This we are doing to set our companies Enterprise registry as our default registry.

You can try other given solutions also.

pip install mysql-connector

Last but not least,You can also install mysql-connector via source code

Download source code from: https://dev.mysql.com/downloads/connector/python/

Have you tried height: auto; on your .container div?

Here is a fiddle, if you change img height, container height will adjust to it.

EDIT

So if you "can't" change the inline min-height, you can overwrite the inline style with an !important parameter. It's not the cleanest way, but it solves your problem.

add to your .containerclass this line

min-height:0px !important;

I've updated my fiddle to give you an example.

ok, you may use substr in correlation to instr to find the starting position of your string

select 
  dbms_lob.substr(
       product_details, 
       length('NEW.PRODUCT_NO'), --amount
       dbms_lob.instr(product_details,'NEW.PRODUCT_NO') --offset
       ) 
from my_table
where dbms_lob.instr(product_details,'NEW.PRODUCT_NO')>=1;

I find the small utility AsmSpy an invaluable tool to for resolving issues with loading assemblies. It lists all assembly references of managed assemblies including assembly versions.

Run it in a command prompt in the directory of the .dll with the following arguments:

asmspy . all

Install it quickly with Chocolatey:

choco install asmspy

You can use this function, ORACLE DB

 public string getMaximumSequenceOfUser(string columnName, string tableName, string username)
    {
        string result = "";
        var query = string.Format("Select MAX ({0})from {1} where CREATED_BY = {2}", columnName, tableName, username.ToLower());

        OracleConnection conn = new OracleConnection(_context.Database.Connection.ConnectionString);
        OracleCommand cmd = new OracleCommand(query, conn);
        try
        {
            conn.Open();
            OracleDataReader dr = cmd.ExecuteReader();
            dr.Read();
            result = dr[0].ToString();
            dr.Dispose();
        }
        finally
        {
            conn.Close();
        }
        return result;
    }

Your hyphen in your ELSE statement isn't accepted in the column which is being defined under the datetime data type. You could either:

a) Wrap a CAST around your [stat] field to convert it to a varchar representation of a date

b) Use a datetime like 9999-12-31 for your ELSE value.

Change your storage engine to InnoDB by going to Operation

Center vertically and horizontally:

.parent{
  height: 100%;
  position: absolute;
  width: 100%;
  top: 0;
  left: 0;
}
.c{
  position: absolute;
  top: 50%;
  left: 0;
  right: 0;
  transform: translateY(-50%);
}

Most simple syntax would be:

{
    var where = new MyObject();
    where.property = "xxx";
    where.SomeFunction("yyy");
}

{
    var where = new MyObject();
    where.property = "zzz";
    where.SomeFunction("uuu");
}

Actually extra code-blocks like that are very handy if you want to re-use variable names.

The answer provided by @DSM is simple and straightforward, but I thought I'd add my own input to this question. If you look at the code for pandas.value_counts, you'll see that there is a lot going on.

If you need to calculate the frequency of many series, this could take a while. A faster implementation would be to use numpy.unique with return_counts = True

Here is an example:

import pandas as pd
import numpy as np

my_series = pd.Series([1,2,2,3,3,3])

print(my_series.value_counts())
3    3
2    2
1    1
dtype: int64

Notice here that the item returned is a pandas.Series

In comparison, numpy.unique returns a tuple with two items, the unique values and the counts.

vals, counts = np.unique(my_series, return_counts=True)
print(vals, counts)
[1 2 3] [1 2 3]

You can then combine these into a dictionary:

results = dict(zip(vals, counts))
print(results)
{1: 1, 2: 2, 3: 3}

And then into a pandas.Series

print(pd.Series(results))
1    1
2    2
3    3
dtype: int64

You can use the /s switch for del to delete in subfolders as well.

Example

del D:\test\*.* /s

Would delete all files under test including all files in all subfolders.

To remove folders use rd, same switch applies.

rd D:\test\folder /s /q

rd doesn't support wildcards * though so if you want to recursively delete all subfolders under the test directory you can use a for loop.

for /r /d D:\test %a in (*) do rd %a /s /q

If you are using the for option in a batch file remember to use 2 %'s instead of 1.

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

I'm writing an OpenCL 1.2 backend for Tensorflow at https://github.com/hughperkins/tensorflow-cl

This fork of tensorflow for OpenCL has the following characteristics:

• it targets any/all OpenCL 1.2 devices. It doesnt need OpenCL 2.0, doesnt need SPIR-V, or SPIR. Doesnt need Shared Virtual Memory. And so on ...
• it's based on an underlying library called 'cuda-on-cl', https://github.com/hughperkins/cuda-on-cl
  • cuda-on-cl targets to be able to take any NVIDIA® CUDA™ soure-code, and compile it for OpenCL 1.2 devices. It's a very general goal, and a very general compiler
• for now, the following functionalities are implemented:
  • per-element operations, using Eigen over OpenCL, (more info at https://bitbucket.org/hughperkins/eigen/src/eigen-cl/unsupported/test/cuda-on-cl/?at=eigen-cl )
  • blas / matrix-multiplication, using Cedric Nugteren's CLBlast https://github.com/cnugteren/CLBlast
  • reductions, argmin, argmax, again using Eigen, as per earlier info and links
  • learning, trainers, gradients. At least, StochasticGradientDescent trainer is working, and the others are commited, but not yet tested
• it is developed on Ubuntu 16.04 (using Intel HD5500, and NVIDIA GPUs) and Mac Sierra (using Intel HD 530, and Radeon Pro 450)

This is not the only OpenCL fork of Tensorflow available. There is also a fork being developed by Codeplay https://www.codeplay.com , using Computecpp, https://www.codeplay.com/products/computesuite/computecpp Their fork has stronger requirements than my own, as far as I know, in terms of which specific GPU devices it works on. You would need to check the Platform Support Notes (at the bottom of hte computecpp page), to determine whether your device is supported. The codeplay fork is actually an official Google fork, which is here: https://github.com/benoitsteiner/tensorflow-opencl

Experienced the same error, for me it was caused because on my Mac I have changed the DocumentRoot to my users Sites directory.

To fix it, I ran the recursive command to ensure that the Apache service has read permissions.

sudo chmod -R 755 ~/Sites

The answer above covers everything in great detail, apart from a couple of things.

First, if there are no styles, then the (Context context, AttributeSet attrs) method signature will be used to instantiate the preference. In this case just use context.obtainStyledAttributes(attrs, R.styleable.MyCustomView) to get the TypedArray.

Secondly it does not cover how to deal with plaurals resources (quantity strings). These cannot be dealt with using TypedArray. Here is a code snippet from my SeekBarPreference that sets the summary of the preference formatting its value according to the value of the preference. If the xml for the preference sets android:summary to a text string or a string resouce the value of the preference is formatted into the string (it should have %d in it, to pick up the value). If android:summary is set to a plaurals resource, then that is used to format the result.

// Use your own name space if not using an android resource.
final static private String ANDROID_NS = 
    "http://schemas.android.com/apk/res/android";
private int pluralResource;
private Resources resources;
private String summary;

public SeekBarPreference(Context context, AttributeSet attrs) {
    // ...
    TypedArray attributes = context.obtainStyledAttributes(
        attrs, R.styleable.SeekBarPreference);
    pluralResource =  attrs.getAttributeResourceValue(ANDROID_NS, "summary", 0);
    if (pluralResource !=  0) {
        if (! resources.getResourceTypeName(pluralResource).equals("plurals")) {
            pluralResource = 0;
        }
    }
    if (pluralResource ==  0) {
        summary = attributes.getString(
            R.styleable.SeekBarPreference_android_summary);
    }
    attributes.recycle();
}

@Override
public CharSequence getSummary() {
    int value = getPersistedInt(defaultValue);
    if (pluralResource != 0) {
        return resources.getQuantityString(pluralResource, value, value);
    }
    return (summary == null) ? null : String.format(summary, value);
}

• This is just given as an example, however, if you want are tempted to set the summary on the preference screen, then you need to call notifyChanged() in the preference's onDialogClosed method.

For tracking changes to a folder where the folder was moved, I started using:

git rev-list --all --pretty=oneline -- "*/foo/subfoo/*"

This isn't perfect as it will grab other folders with the same name, but if it is unique, then it seems to work.

You could use apply() and do something like this

df['que'] = df.apply(lambda x : x['one'] if x['one'] >= x['two'] and x['one'] <= x['three'] else "", axis=1)

or if you prefer not to use a lambda

def que(x):
    if x['one'] >= x['two'] and x['one'] <= x['three']:
        return x['one']
    return ''
df['que'] = df.apply(que, axis=1)

Disclosure: I wrote FieldVal.

Here is a solution using FieldVal. By using FieldVal UI to build a form and then FieldVal to validate the input, you can pass the error straight back into the form.

You can even run the validation code on the backend (if you're using Node.js) and show the error in the form without wiring all of the fields up manually.

Live demo: http://codepen.io/MarcusLongmuir/pen/WbOydx

function validate_form(data) {
    // This would work on the back end too (if you're using Node)

    // Validate the provided data
    var validator = new FieldVal(data);
    validator.get("email", BasicVal.email(true));
    validator.get("title", BasicVal.string(true));
    validator.get("url", BasicVal.url(true));
    return validator.end();
}


$(document).ready(function(){

    // Create a form and add some fields
    var form = new FVForm()
    .add_field("email", new FVTextField("Email"))
    .add_field("title", new FVTextField("Title"))
    .add_field("url", new FVTextField("URL"))
    .on_submit(function(value){

        // Clear the existing errors
        form.clear_errors();

        // Use the function above to validate the input
        var error = validate_form(value);

        if (error) {
            // Pass the error into the form
            form.error(error);
        } else {
            // Use the data here
            alert(JSON.stringify(value));
        }
    })

    form.element.append(
        $("<button/>").text("Submit")
    ).appendTo("body");

    //Pre-populate the form
    form.val({
        "email": "[email protected]",
        "title": "Your Title",
        "url": "http://www.example.com"
    })
});

1. download current stable release version of your chrome & install it ( to check your Google chrome version go to Help > about Google chrome & try to install that version on your local machine .

For Google chrome version downloading visit = chromedriver.chromium.org site

        }
        else
        {
            Intent intent=new Intent(MainActivity.this,Scan_QRActivity.class);

There is a special identifier that one can use in a formula to mean all the variables, it is the . identifier.

y <- c(1,4,6)
d <- data.frame(y = y, x1 = c(4,-1,3), x2 = c(3,9,8), x3 = c(4,-4,-2))
mod <- lm(y ~ ., data = d)

You can also do things like this, to use all variables but one (in this case x3 is excluded):

mod <- lm(y ~ . - x3, data = d)

Technically, . means all variables not already mentioned in the formula. For example

lm(y ~ x1 * x2 + ., data = d)

where . would only reference x3 as x1 and x2 are already in the formula.

You want

#content div:first-child {
/*css*/
}

You can find the number of members in a Javascript array by using its length property:

var number = $scope.names.length;

^{Docs - Array.prototype.length}

You don't need SSH for sharing git. If you're on a LAN or VPN, you can export a git project as a shared folder, and mount it on a remote machine. Then configure the remote repo using "file://" URLs instead of "git@" URLs. Takes all of 30 seconds. Done!

To clone that repository via a URL like that: yes, you do need a client, and that client is Git. That will let you make changes, your own branches, merge back in sync with other developers, maintain your own source that you can easily keep up to date without downloading the whole thing each time and writing over your own changes etc. A ZIP file won't let you do that.

It is mostly meant for people who want to develop the source rather than people who just want to get the source one off and not make changes.

But it just so happens you can get a ZIP file as well:

Click on http://github.com/zoul/Finch/ and then click on the green Clone or Download button. See here:

Easy way out is to use a condition like this ( use desired date > GETDATE()-1)

your sql statement "date specific" > GETDATE()-1

It means you're passing the variable by reference.

In fact, in a declaration of a type, it means reference, just like:

int x = 42;
int& y = x;

declares a reference to x, called y.

If you face the same error, here are the step by step instructions:

1. Open control panel
2. Then go to System
3. Then go to Change Environment Variables of the User
4. Then click create a new environment variables
5. Create a new variable named ANDROID_SDK_HOME
6. Set its value to your Android directory, like C:/users/<username>/.android

In TorpedoQuery it look like this

Entity from = from(Entity.class);
where(from.getCode()).in("Joe", "Bob");
Query<Entity> select = select(from);

You will need to get the textbox via javascript when moving the mouse over it and change its type to text. And when moving it out, you will want to change it back to password. No chance of doing this in pure CSS.

HTML:

<input type="password" name="password" id="myPassword" size="30" />
<img src="theicon" onmouseover="mouseoverPass();" onmouseout="mouseoutPass();" />

JS:

function mouseoverPass(obj) {
  var obj = document.getElementById('myPassword');
  obj.type = "text";
}
function mouseoutPass(obj) {
  var obj = document.getElementById('myPassword');
  obj.type = "password";
}

I made a bit more of a generic filter that I've used in multiple projects already:

• object = the object that needs to be filtered
• field = the field within that object that we'll filter on
• filter = the value of the filter that needs to match the field

HTML:

<input ng-model="customerNameFilter" />
<div ng-repeat="(key, value) in filter(customers, 'customerName', customerNameFilter" >
   <p>Number: {{value.customerNo}}</p>
   <p>Name: {{value.customerName}}</p>
</div>

JS:

  $scope.filter = function(object, field, filter) {
    if (!object) return {};
    if (!filter) return object;

    var filteredObject = {};
    Object.keys(object).forEach(function(key) {
      if (object[key][field] === filter) {
        filteredObject[key] = object[key];
      }
    });

    return filteredObject;
  };

Suppose I have this line of scripts in my "package.json"

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "export_advertisements": "node export.js advertisements",
    "export_homedata": "node export.js homedata",
    "export_customdata": "node export.js customdata",
    "export_rooms": "node export.js rooms"
  },

Now to run the script "export_advertisements", I will simply go to the terminal and type

npm run export_advertisements

You are most welcome

Try

<div style="max-width:200px; word-wrap:break-word;">Texttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt</div>

To expand on persistent's answer, and to provide more of the functionality of NUnit, you can do this:

public bool AssertThrows<TException>(
    Action action,
    Func<TException, bool> exceptionCondition = null)
    where TException : Exception
{
    try
    {
        action();
    }
    catch (TException ex)
    {
        if (exceptionCondition != null)
        {
            return exceptionCondition(ex);
        }
        return true;
    }
    catch
    {
        return false;
    }

    return false;
}

Examples:

// No exception thrown - test fails.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => {}));

// Wrong exception thrown - test fails.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new ApplicationException(); }));

// Correct exception thrown - test passes.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new InvalidOperationException(); }));

// Correct exception thrown, but wrong message - test fails.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new InvalidOperationException("ABCD"); },
        ex => ex.Message == "1234"));

// Correct exception thrown, with correct message - test passes.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new InvalidOperationException("1234"); },
        ex => ex.Message == "1234"));

Slightly beside the actual question, but nonetheless useful: The Help menu of Intellij has an option 'Default Keymap reference', which opens a PDF with the complete mapping. (Ctrl+F12 is mentioned there)

Pass java.text.Collator.getInstance() to Collections.sort method ; it will sort Alphabetically while ignoring case sensitive.

        ArrayList<String> myArray = new ArrayList<String>();
        myArray.add("zzz");
        myArray.add("xxx");
        myArray.add("Aaa");
        myArray.add("bb");
        myArray.add("BB");
        Collections.sort(myArray,Collator.getInstance());

I'm using Maven (SpringBoot application) solution is:

1. Right click project folder
2. Select Maven
3. Select Generate Sources And Update Folders

Then, Intellij automatically import generated sources to project.

This can also be achieved like this (very easy way)

 class app extends Component {
   state = {
     show: false
   };
 toggle= () => {
   var res = this.state.show;
   this.setState({ show: !res });
 };
render() {
  return(
   <button onClick={ this.toggle }> Toggle </button>
  {
    this.state.show ? (<div> HELLO </div>) : null
  }
   );
     }

TLDR; Neither use the synchronized modifier nor the synchronized(this){...} expression but synchronized(myLock){...} where myLock is a final instance field holding a private object.

The difference between using the synchronized modifier on the method declaration and the synchronized(..){ } expression in the method body are this:

• The synchronized modifier specified on the method's signature
  1. is visible in the generated JavaDoc,
  2. is programmatically determinable via reflection when testing a method's modifier for Modifier.SYNCHRONIZED,
  3. requires less typing and indention compared to synchronized(this) { .... }, and
  4. (depending on your IDE) is visible in the class outline and code completion,
  5. uses the this object as lock when declared on non-static method or the enclosing class when declared on a static method.
• The synchronized(...){...} expression allows you
  1. to only synchronize the execution of parts of a method's body,
  2. to be used within a constructor or a (static) initialization block,
  3. to choose the lock object which controls the synchronized access.

However, using the synchronized modifier or synchronized(...) {...} with this as the lock object (as in synchronized(this) {...}), have the same disadvantage. Both use it's own instance as the lock object to synchronize on. This is dangerous because not only the object itself but any other external object/code that holds a reference to that object can also use it as a synchronization lock with potentially severe side effects (performance degradation and deadlocks).

Therefore best practice is to neither use the synchronized modifier nor the synchronized(...) expression in conjunction with this as lock object but a lock object private to this object. For example:

public class MyService {
    private final lock = new Object();

    public void doThis() {
       synchronized(lock) {
          // do code that requires synchronous execution
        }
    }

    public void doThat() {
       synchronized(lock) {
          // do code that requires synchronous execution
        }
    }
}

You can also use multiple lock objects but special care needs to be taken to ensure this does not result in deadlocks when used nested.

public class MyService {
    private final lock1 = new Object();
    private final lock2 = new Object();

    public void doThis() {
       synchronized(lock1) {
          synchronized(lock2) {
              // code here is guaranteed not to be executes at the same time
              // as the synchronized code in doThat() and doMore().
          }
    }

    public void doThat() {
       synchronized(lock1) {
              // code here is guaranteed not to be executes at the same time
              // as the synchronized code in doThis().
              // doMore() may execute concurrently
        }
    }

    public void doMore() {
       synchronized(lock2) {
              // code here is guaranteed not to be executes at the same time
              // as the synchronized code in doThis().
              // doThat() may execute concurrently
        }
    }
}

You can just use the built-in function count follow by the groupby function

df.groupby(['col5','col2']).count()

You can use this method to log the exception stack to String

 public String stackTraceToString(Throwable e) {
    StringBuilder sb = new StringBuilder();
    for (StackTraceElement element : e.getStackTrace()) {
        sb.append(element.toString());
        sb.append("\n");
    }
    return sb.toString();
}

Direct add this line with your color code

getSupportActionBar().setBackgroundDrawable(
    new ColorDrawable(Color.parseColor("#5e9c00")));

not need to create ActionBar object every time...

     CASE
     WHEN col IS NULL
        THEN ''
     ELSE SUBSTRING(col,1,15)+ '...' 
     END AS Col

You've answered the question with this statement:

Cron calls this .sh every 2 minutes

Cron does not run in a terminal, so why would you expect one to be set?

The most common reason for getting this error message is because the script attempts to source the user's .profile which does not check that it's running in a terminal before doing something tty related. Workarounds include using a shebang line like:

#!/bin/bash -p

Which causes the sourcing of system-level profile scripts which (one hopes) does not attempt to do anything too silly and will have guards around code that depends on being run from a terminal.

If this is the entirety of the script, then the TERM error is coming from something other than the plain content of the script.

Depending on how you format (and validate!) the date entered in the textbox, you can do this:

TimeSpan time;

if (TimeSpan.TryParse(textboxTime.Text, out time))
{
   // calendarDate is the DateTime value of the calendar control
   calendarDate = calendarDate.Add(time);
}
else
{
   // notify user about wrong date format
}

Note that TimeSpan.TryParse expects the string to be in the 'hh:mm' format (optional seconds).

1.) First off, what is the correct terminology for an array created on the end of the name element of an input tag in a form?

"Oftimes Confusing PHPism"

As far as JavaScript is concerned a bunch of form controls with the same name are just a bunch of form controls with the same name, and form controls with names that include square brackets are just form controls with names that include square brackets.

The PHP naming convention for form controls with the same name is sometimes useful (when you have a number of groups of controls so you can do things like this:

<input name="name[1]">
<input name="email[1]">
<input name="sex[1]" type="radio" value="m">
<input name="sex[1]" type="radio" value="f">

<input name="name[2]">
<input name="email[2]">
<input name="sex[2]" type="radio" value="m">
<input name="sex[2]" type="radio" value="f">

) but does confuse some people. Some other languages have adopted the convention since this was originally written, but generally only as an optional feature. For example, via this module for JavaScript.

2.) How do I get the information from that array with JavaScript?

It is still just a matter of getting the property with the same name as the form control from elements. The trick is that since the name of the form controls includes square brackets, you can't use dot notation and have to use square bracket notation just like any other JavaScript property name that includes special characters.

Since you have multiple elements with that name, it will be a collection rather then a single control, so you can loop over it with a standard for loop that makes use of its length property.

var myForm = document.forms.id_of_form;
var myControls = myForm.elements['p_id[]'];
for (var i = 0; i < myControls.length; i++) {
    var aControl = myControls[i];
}

You are missing an include : #include <stdlib.h>, so GCC creates an implicit declaration of atof and atod, leading to garbage values.

And the format specifier for double is %f, not %d (that is for integers).

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

int main()
{
  char *test = "12.11";
  double temp = strtod(test,NULL);
  float ftemp = atof(test);
  printf("price: %f, %f",temp,ftemp);
  return 0;
}
/* Output */
price: 12.110000, 12.110000

SWT puts the necessary native DLLs into a JAR. Search for "org.eclipse.swt.win32.win32.x86_3.4.1.v3449c.jar" for an example.

The DLLs must be in the root of the JAR, the JAR must be signed and the DLL must appear with checksum in the META-INF/MANIFEST.MF for the VM to pick them up.

Define this in your String.xml file and name the array what you want, such as "Weight"

<string-array name="Weight">
<item>Kg</item>
<item>Gram</item>
<item>Tons</item>
</string-array>

and this code in your layout.xml

<Spinner 
        android:id="@+id/fromspin"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:entries="@array/Weight"
 />

In your java file, getActivity is used in fragment; if you write that code in activity, then remove getActivity.

a = (Spinner) findViewById(R.id.fromspin);

 ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this.getActivity(),
                R.array.weight, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        a.setAdapter(adapter);
        a.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
                if (a.getSelectedItem().toString().trim().equals("Kilogram")) {
                    if (!b.getText().toString().isEmpty()) {
                        float value1 = Float.parseFloat(b.getText().toString());
                        float kg = value1;
                        c.setText(Float.toString(kg));
                        float gram = value1 * 1000;
                        d.setText(Float.toString(gram));
                        float carat = value1 * 5000;
                        e.setText(Float.toString(carat));
                        float ton = value1 / 908;
                        f.setText(Float.toString(ton));
                    }

                }



            public void onNothingSelected(AdapterView<?> parent) {
                // Another interface callback
            }
        });
        // Inflate the layout for this fragment
        return v;
    }

Just to clarify, you can't do location.split('#'), location is an object, not a string. But you can do location.href.split('#'); because location.href is a string.

To default-initialize an array of Ts, T must be default constructible. Normally the compiler gives you a default constructor for free. However, since you declared a constructor yourself, the compiler does not generate a default constructor.

Your options:

• add a default constructor to name, if that makes sense (I don't think so, but I don't know the problem domain);

• initialize all the elements of the array upon declaration (you can do this because name is an aggregate);

    name someName[4] = { { "Arthur", "Dent" },
                         { "Ford", "Prefect" },
                         { "Tricia", "McMillan" },
                         { "Zaphod", "Beeblebrox" }
                       };
  

• use a std::vector instead, and only add element when you have them constructed.

Before asking questions of this kind, please check MSDN documentation.

When you divide two integers, the result is always an integer. For example, the result of 7 / 3 is 2. To determine the remainder of 7 / 3, use the remainder operator (%).

int a = 5;
int b = 3;

int div = a / b; //quotient is 1
int mod = a % b; //remainder is 2

You can use sklearn.preprocessing:

from sklearn.preprocessing import normalize
data = np.array([
    [1000, 10, 0.5],
    [765, 5, 0.35],
    [800, 7, 0.09], ])
data = normalize(data, axis=0, norm='max')
print(data)
>>[[ 1.     1.     1.   ]
[ 0.765  0.5    0.7  ]
[ 0.8    0.7    0.18 ]]

Mount a "volume" and copy the artifacts into there:

mkdir artifacts
docker run -i -v ${PWD}/artifacts:/artifacts ubuntu:14.04 sh << COMMANDS
# ... build software here ...
cp <artifact> /artifacts
# ... copy more artifacts into `/artifacts` ...
COMMANDS

Then when the build finishes and the container is no longer running, it has already copied the artifacts from the build into the artifacts directory on the host.

Edit

Caveat: When you do this, you may run into problems with the user id of the docker user matching the user id of the current running user. That is, the files in /artifacts will be shown as owned by the user with the UID of the user used inside the docker container. A way around this may be to use the calling user's UID:

docker run -i -v ${PWD}:/working_dir -w /working_dir -u $(id -u) \
    ubuntu:14.04 sh << COMMANDS
# Since $(id -u) owns /working_dir, you should be okay running commands here
# and having them work. Then copy stuff into /working_dir/artifacts .
COMMANDS

To avoid autocomplete add the autocomplete="off" to your html input property.

Example:

<input type="text" name="foo" autocomplete="off" />

SQL Server recognizes 'TRUE' and 'FALSE' as bit values. So, use a bit data type!

declare @var bit
set @var = 'true'
print @var

That returns 1.

There is at least one middleware on npm for handling CORS in Express: cors. [see @mscdex answer]

This is how to set custom response headers, from the ExpressJS DOC

res.set(field, [value])

Set header field to value

res.set('Content-Type', 'text/plain');

or pass an object to set multiple fields at once.

res.set({
  'Content-Type': 'text/plain',
  'Content-Length': '123',
  'ETag': '12345'
})

Aliased as

res.header(field, [value])

One can also use the java.util.EnumSet like this

@Test
void test(){
    Enum aEnum =DayOfWeek.MONDAY;
    printAll(aEnum);
}

void printAll(Enum value){
    Set allValues = EnumSet.allOf(value.getClass());
    System.out.println(allValues);
}

Generators could be thought of as shorthand for creating an iterator. They behave like a Java Iterator. Example:

>>> g = (x for x in range(10))
>>> g
<generator object <genexpr> at 0x7fac1c1e6aa0>
>>> g.next()
0
>>> g.next()
1
>>> g.next()
2
>>> list(g)   # force iterating the rest
[3, 4, 5, 6, 7, 8, 9]
>>> g.next()  # iterator is at the end; calling next again will throw
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
StopIteration

Hope this helps/is what you are looking for.

Update:

As many other answers are showing, there are different ways to create a generator. You can use the parentheses syntax as in my example above, or you can use yield. Another interesting feature is that generators can be "infinite" -- iterators that don't stop:

>>> def infinite_gen():
...     n = 0
...     while True:
...         yield n
...         n = n + 1
... 
>>> g = infinite_gen()
>>> g.next()
0
>>> g.next()
1
>>> g.next()
2
>>> g.next()
3
...

Simple way to initiate the message on startup:

bot.on('ready', () => {
    bot.user.setStatus('available')
    bot.user.setPresence({
        game: {
            name: 'with depression',
            type: "STREAMING",
            url: "https://www.twitch.tv/monstercat"
        }
    });
});

You can also just declare it elsewhere after startup, to change the message as needed:

bot.user.setPresence({ game: { name: 'with depression', type: "streaming", url: "https://www.twitch.tv/monstercat"}}); 

Maven complains if you do not have admin permissions on the target folder.Check if you have admin right to delete that folder.

You could do this, given an array a of primitive type:

StringBuffer result = new StringBuffer();
for (int i = 0; i < a.length; i++) {
   result.append( a[i] );
   //result.append( optional separator );
}
String mynewstring = result.toString();

I originally posted the benchmarks below with the purpose of recommending numpy.corrcoef, foolishly not realizing that the original question already uses corrcoef and was in fact asking about higher order polynomial fits. I've added an actual solution to the polynomial r-squared question using statsmodels, and I've left the original benchmarks, which while off-topic, are potentially useful to someone.

statsmodels has the capability to calculate the r^2 of a polynomial fit directly, here are 2 methods...

import statsmodels.api as sm
import statsmodels.formula.api as smf

# Construct the columns for the different powers of x
def get_r2_statsmodels(x, y, k=1):
    xpoly = np.column_stack([x**i for i in range(k+1)])    
    return sm.OLS(y, xpoly).fit().rsquared

# Use the formula API and construct a formula describing the polynomial
def get_r2_statsmodels_formula(x, y, k=1):
    formula = 'y ~ 1 + ' + ' + '.join('I(x**{})'.format(i) for i in range(1, k+1))
    data = {'x': x, 'y': y}
    return smf.ols(formula, data).fit().rsquared # or rsquared_adj

To further take advantage of statsmodels, one should also look at the fitted model summary, which can be printed or displayed as a rich HTML table in Jupyter/IPython notebook. The results object provides access to many useful statistical metrics in addition to rsquared.

model = sm.OLS(y, xpoly)
results = model.fit()
results.summary()

Below is my original Answer where I benchmarked various linear regression r^2 methods...

The corrcoef function used in the Question calculates the correlation coefficient, r, only for a single linear regression, so it doesn't address the question of r^2 for higher order polynomial fits. However, for what it's worth, I've come to find that for linear regression, it is indeed the fastest and most direct method of calculating r.

def get_r2_numpy_corrcoef(x, y):
    return np.corrcoef(x, y)[0, 1]**2

These were my timeit results from comparing a bunch of methods for 1000 random (x, y) points:

• Pure Python (direct r calculation)
  • 1000 loops, best of 3: 1.59 ms per loop
• Numpy polyfit (applicable to n-th degree polynomial fits)
  • 1000 loops, best of 3: 326 µs per loop
• Numpy Manual (direct r calculation)
  • 10000 loops, best of 3: 62.1 µs per loop
• Numpy corrcoef (direct r calculation)
  • 10000 loops, best of 3: 56.6 µs per loop
• Scipy (linear regression with r as an output)
  • 1000 loops, best of 3: 676 µs per loop
• Statsmodels (can do n-th degree polynomial and many other fits)
  • 1000 loops, best of 3: 422 µs per loop

The corrcoef method narrowly beats calculating the r^2 "manually" using numpy methods. It is >5X faster than the polyfit method and ~12X faster than the scipy.linregress. Just to reinforce what numpy is doing for you, it's 28X faster than pure python. I'm not well-versed in things like numba and pypy, so someone else would have to fill those gaps, but I think this is plenty convincing to me that corrcoef is the best tool for calculating r for a simple linear regression.

Here's my benchmarking code. I copy-pasted from a Jupyter Notebook (hard not to call it an IPython Notebook...), so I apologize if anything broke on the way. The %timeit magic command requires IPython.

a common error i run into from time to time, is that i forget the -p option, so are you sure you used:

mysql -u root -p

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

The compiler actually adds an argument to non-static methods. It adds a this pointer/reference. This is also the reason why a static method can not use this, because there is no object.

If you are not sharing develop branch with anybody, then I would just rebase it every time master updated, that way you will not have merge commits all over your history once you will merge develop back into master. Workflow in this case would be as follows:

> git clone git://<remote_repo_path>/ <local_repo>
> cd <local_repo>
> git checkout -b develop
....do a lot of work on develop
....do all the commits
> git pull origin master
> git rebase master develop

Above steps will ensure that your develop branch will be always on top of the latest changes from the master branch. Once you are done with develop branch and it's rebased to the latest changes on master you can just merge it back:

> git checkout -b master
> git merge develop
> git branch -d develop

What do you want to search near that known place?

For example if you want to search a restaurant near a known place you can use the parameters "q=" and "near=" and construct this URL: maps.google.com/?q=restaurant&near=47.154719,27.60551

For a list of complete parameters you can see this: https://web.archive.org/web/20070708030513/http://mapki.com/wiki/Google_Map_Parameters

Depending on what is the format you want your information in you can add at the end of the url the parameter output like this: maps.google.com/?q=restaurant&near=47.154719,27.60551&output=kml

For more types of output format you can read chapter 2 of this: http://csie-tw.blogspot.de/2009/06/android-driving-direction-route-path.html

The cleanest solution that I've seen is:

from distutils.util import strtobool
def string_to_bool(string):
    return bool(strtobool(str(string)))

Sure, it requires an import, but it has proper error handling and requires very little code to be written (and tested).

I do not understand why the answers are so complex. In Javascript, primitives (strings, numbers, etc) are passed by value, and copied. Objects, including arrays, are passed by reference. In any case, assignment of a new value or object reference to 'a' will not change 'b'. But changing the contents of 'a' will change the contents of 'b'.

var a = 'a'; var b = a; a = 'c'; // b === 'a'

var a = {a:'a'}; var b = a; a = {c:'c'}; // b === {a:'a'} and a = {c:'c'}

var a = {a:'a'}; var b = a; a.a = 'c'; // b.a === 'c' and a.a === 'c'

Paste any of the above lines (one at a time) into node or any browser javascript console. Then type any variable and the console will show it's value.

edit to my previous answer: if you want to count a function's invocations, you might want to try:

var countMe = ( function() {
  var c = 0;

  return function() {
    c++;
    return c;
  }
})();

alert(countMe()); // Alerts "1"
alert(countMe()); // Alerts "2"

Here, c serves as the counter, and you do not have to use arguments.callee.

Google Spreadsheets and .NET Core

It references Google.Api.Sheets.v4 and OAuth2.

An utility method like the following can be used to solve this.

import (
  "os"
  "path/filepath"
  "log"
)

func ensureDir(fileName string) {
  dirName := filepath.Dir(fileName)
  if _, serr := os.Stat(dirName); serr != nil {
    merr := os.MkdirAll(dirName, os.ModePerm)
    if merr != nil {
        panic(merr)
    }
  }
}



func main() {
  _, cerr := os.Create("a/b/c/d.txt")
  if cerr != nil {
    log.Fatal("error creating a/b/c", cerr)
  }
  log.Println("created file in a sub-directory.")
}

You can also selected headers to every axios request:

// Add a request interceptor
axios.interceptors.request.use(function (config) {
    config.headers.Authorization = 'AUTH_TOKEN';
    return config;
});

Second method

axios.defaults.headers.common['Authorization'] = 'AUTH_TOKEN';

I would use @HostListener decorator within your component:

import { HostListener } from '@angular/core';

@Component({
  ...
})
export class AppComponent {

  @HostListener('document:keypress', ['$event'])
  handleKeyboardEvent(event: KeyboardEvent) { 
    this.key = event.key;
  }
}

There are also other options like:

host property within @Component decorator

Angular recommends using @HostListener decorator over host property https://angular.io/guide/styleguide#style-06-03

@Component({
  ...
  host: {
    '(document:keypress)': 'handleKeyboardEvent($event)'
  }
})
export class AppComponent {
  handleKeyboardEvent(event: KeyboardEvent) {
    console.log(event);
  }
}

renderer.listen

import { Component, Renderer2 } from '@angular/core';

@Component({
  ...
})
export class AppComponent {
  globalListenFunc: Function;

  constructor(private renderer: Renderer2) {}

  ngOnInit() {
    this.globalListenFunc = this.renderer.listen('document', 'keypress', e => {
      console.log(e);
    });
  }

  ngOnDestroy() {
    // remove listener
    this.globalListenFunc();
  }
}

Observable.fromEvent

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/fromEvent';
import { Subscription } from 'rxjs/Subscription';

@Component({
  ...
})
export class AppComponent {
  subscription: Subscription;

  ngOnInit() {
    this.subscription = Observable.fromEvent(document, 'keypress').subscribe(e => {
      console.log(e);
    })
  }

  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

Just access the element and append it to the value.

<input
     type="button" 
     onclick="document.getElementById('myTextArea').value += '•'" 
     value="Add •">

See a live demo.

For the sake of keeping things simple, I haven't written unobtrusive JS. For a production system you should.

Also it needs to be a UTF8 character.

Browsers generally submit forms using the encoding they received the page in. Serve your page as UTF-8 if you want UTF-8 data submitted back.

The main reason is that classic C casts make no distinction between what we call static_cast<>(), reinterpret_cast<>(), const_cast<>(), and dynamic_cast<>(). These four things are completely different.

A static_cast<>() is usually safe. There is a valid conversion in the language, or an appropriate constructor that makes it possible. The only time it's a bit risky is when you cast down to an inherited class; you must make sure that the object is actually the descendant that you claim it is, by means external to the language (like a flag in the object). A dynamic_cast<>() is safe as long as the result is checked (pointer) or a possible exception is taken into account (reference).

A reinterpret_cast<>() (or a const_cast<>()) on the other hand is always dangerous. You tell the compiler: "trust me: I know this doesn't look like a foo (this looks as if it isn't mutable), but it is".

The first problem is that it's almost impossible to tell which one will occur in a C-style cast without looking at large and disperse pieces of code and knowing all the rules.

Let's assume these:

class CDerivedClass : public CMyBase {...};
class CMyOtherStuff {...} ;

CMyBase  *pSomething; // filled somewhere

Now, these two are compiled the same way:

CDerivedClass *pMyObject;
pMyObject = static_cast<CDerivedClass*>(pSomething); // Safe; as long as we checked

pMyObject = (CDerivedClass*)(pSomething); // Same as static_cast<>
                                     // Safe; as long as we checked
                                     // but harder to read

However, let's see this almost identical code:

CMyOtherStuff *pOther;
pOther = static_cast<CMyOtherStuff*>(pSomething); // Compiler error: Can't convert

pOther = (CMyOtherStuff*)(pSomething);            // No compiler error.
                                                  // Same as reinterpret_cast<>
                                                  // and it's wrong!!!

As you can see, there is no easy way to distinguish between the two situations without knowing a lot about all the classes involved.

The second problem is that the C-style casts are too hard to locate. In complex expressions it can be very hard to see C-style casts. It is virtually impossible to write an automated tool that needs to locate C-style casts (for example a search tool) without a full blown C++ compiler front-end. On the other hand, it's easy to search for "static_cast<" or "reinterpret_cast<".

pOther = reinterpret_cast<CMyOtherStuff*>(pSomething);
      // No compiler error.
      // but the presence of a reinterpret_cast<> is 
      // like a Siren with Red Flashing Lights in your code.
      // The mere typing of it should cause you to feel VERY uncomfortable.

That means that, not only are C-style casts more dangerous, but it's a lot harder to find them all to make sure that they are correct.

The WITH syntax appears to be valid in an inline view, e.g.

UPDATE (WITH comp AS ...
        SELECT SomeColumn, ComputedValue FROM t INNER JOIN comp ...)
   SET SomeColumn=ComputedValue;

But in the quick tests I did this always failed with ORA-01732: data manipulation operation not legal on this view, although it succeeded if I rewrote to eliminate the WITH clause. So the refactoring may interfere with Oracle's ability to guarantee key-preservation.

You should be able to use a MERGE, though. Using the simple example you've posted this doesn't even require a WITH clause:

MERGE INTO mytable t
USING (select *, 42 as ComputedValue from mytable where id = 1) comp
ON (t.id = comp.id)
WHEN MATCHED THEN UPDATE SET SomeColumn=ComputedValue;

But I understand you have a more complex subquery you want to factor out. I think that you will be able to make the subquery in the USING clause arbitrarily complex, incorporating multiple WITH clauses.

Alternative #1

Use the target and lib compiler options to compile directly to es5 without needing to install the es6-shim. (Tested with TypeScript 2.1.4). In the lib section, use either es2016 or es2015.promise.

// tsconfig.json
{
    "compilerOptions": {
        "target": "es5",
        "lib": [
            "es2015.promise",
            "dom"
        ]
    },
    "include": [
        "src/**/*.ts"
    ],
    "exclude": [
        "node_modules"
    ]
}

Alternative #2

Use NPM to install the es6-shim from the types organization.

npm install @types/es6-shim --save-dev

Alternative #3

Before TypeScript 2.0, use typings to install the es6-shim globally from DefinitelyTyped.

npm install typings --global --save-dev
typings install dt~es6-shim --global --save-dev

The typings option uses npm to install typings globally and then uses typings to install the shim. The dt~ prefix means to download the shim from DefinitelyTyped. The --global option means that the shim's types will be available throughout the project.

The only solution here that worked for me in 5.6.5 was bigstone1998's regex answer. I'd prefer not to use a regex search though for performance reasons. I believe the reason the other solutions don't work is because a standard field will be analyzed and as a result have no empty string token to negate against. The exists query won't help on it's own either since an empty string is considered non-null.

If you can't change the index the regex approach may be your only option, but if you can change the index then adding a keyword subfield will solve the problem.

In the mappings for the index:

"myfield": {
    "type": "text",
    "fields": {
        "keyword": {
            "ignore_above": 256,
            "type": "keyword"
        }
    }
}

Then you can simply use the query:

{
  "query": {
    "bool": {
      "must": {
        "exists": {
          "field": "myfield"
        }
      },
      "must_not": {
        "term": {
          "myfield.keyword": ""
        }
      }
    }
  }
}

Note the .keyword in the must_not component.

My understanding from my testing (and the PostgreSQL dox) is that the quotes need to be done differently from the other answers, and should also include "day" like this:

SELECT Table.date
  FROM Table 
  WHERE date > current_date - interval '10 day';

Demonstrated here (you should be able to run this on any Postgres db):

SELECT DISTINCT current_date, 
                current_date - interval '10' day, 
                current_date - interval '10 days' 
  FROM pg_language;

Result:

2013-03-01  2013-03-01 00:00:00 2013-02-19 00:00:00

Declare these methods first..

public static void putPref(String key, String value, Context context) {
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
    SharedPreferences.Editor editor = prefs.edit();
    editor.putString(key, value);
    editor.commit();
}

public static String getPref(String key, Context context) {
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
    return preferences.getString(key, null);
}

Then call this when you want to put a pref:

putPref("myKey", "mystring", getApplicationContext());

call this when you want to get a pref:

getPref("myKey", getApplicationContext());

Or you can use this object https://github.com/kcochibili/TinyDB--Android-Shared-Preferences-Turbo which simplifies everything even further

Example:

TinyDB tinydb = new TinyDB(context);

tinydb.putInt("clickCount", 2);
tinydb.putFloat("xPoint", 3.6f);
tinydb.putLong("userCount", 39832L);

tinydb.putString("userName", "john");
tinydb.putBoolean("isUserMale", true); 

tinydb.putList("MyUsers", mUsersArray);
tinydb.putImagePNG("DropBox/WorkImages", "MeAtlunch.png", lunchBitmap);

I think that what happens is this:

focus()
   UI tasks related to pre-focus
   callbacks
       select()
   UI tasks related to focus (which unselect again)

A workaround may be calling the select() asynchronously, so that it runs completely after focus():

$("input[type=text]").focus(function() { 
    var save_this = $(this);
    window.setTimeout (function(){ 
       save_this.select(); 
    },100);
});

I also struggled a lot with this issue. The answers in this thread were helpful but were not enough to resolve my error. You will need to disable Hyper-V and Device guard like the other answers have suggested. More info on that can be found in here.

I am including the changes needed to be done in addition to the answers provided above. The link that finally helped me was this.

My answer is going to summarize only the difference between the rest of the answers (i.e. Disabling Hyper-V and Device guard) and the following steps :

1. If you used Group Policy, disable the Group Policy setting that you used to enable Windows Defender Credential Guard (Computer Configuration -> Administrative Templates -> System -> Device Guard -> Turn on Virtualization Based Security).

2. Delete the following registry settings:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA\LsaCfgFlags HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\DeviceGuard\EnableVirtualizationBasedSecurity HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\DeviceGuard\RequirePlatformSecurityFeatures

   Important : If you manually remove these registry settings, make sure to delete them all. If you don't remove them all, the device might go into BitLocker recovery.

3. Delete the Windows Defender Credential Guard EFI variables by using bcdedit. From an elevated command prompt(start in admin mode), type the following commands:

    mountvol X: /s
   
    copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y
   
    bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader
   
    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"
   
    bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}
   
    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO
   
    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:
   
    mountvol X: /d
   

4. Restart the PC.

5. Accept the prompt to disable Windows Defender Credential Guard.

6. Alternatively, you can disable the virtualization-based security features to turn off Windows Defender Credential Guard.

Generating all the indices of a sequence is generally a bad idea, as it might take a lot of time, especially if the ratio of the numbers to be chosen to MAX is low (the complexity becomes dominated by O(MAX)). This gets worse if the ratio of the numbers to be chosen to MAX approaches one, as then removing the chosen indices from the sequence of all also becomes expensive (we approach O(MAX^2/2)). But for small numbers, this generally works well and is not particularly error-prone.

Filtering the generated indices by using a collection is also a bad idea, as some time is spent in inserting the indices into the sequence, and progress is not guaranteed as the same random number can be drawn several times (but for large enough MAX it is unlikely). This could be close to complexity
O(k n log^2(n)/2), ignoring the duplicates and assuming the collection uses a tree for efficient lookup (but with a significant constant cost k of allocating the tree nodes and possibly having to rebalance).

Another option is to generate the random values uniquely from the beginning, guaranteeing progress is being made. That means in the first round, a random index in [0, MAX] is generated:

items i0 i1 i2 i3 i4 i5 i6 (total 7 items)
idx 0       ^^             (index 2)

In the second round, only [0, MAX - 1] is generated (as one item was already selected):

items i0 i1    i3 i4 i5 i6 (total 6 items)
idx 1          ^^          (index 2 out of these 6, but 3 out of the original 7)

The values of the indices then need to be adjusted: if the second index falls in the second half of the sequence (after the first index), it needs to be incremented to account for the gap. We can implement this as a loop, allowing us to select arbitrary number of unique items.

For short sequences, this is quite fast O(n^2/2) algorithm:

void RandomUniqueSequence(std::vector<int> &rand_num,
    const size_t n_select_num, const size_t n_item_num)
{
    assert(n_select_num <= n_item_num);

    rand_num.clear(); // !!

    // b1: 3187.000 msec (the fastest)
    // b2: 3734.000 msec
    for(size_t i = 0; i < n_select_num; ++ i) {
        int n = n_Rand(n_item_num - i - 1);
        // get a random number

        size_t n_where = i;
        for(size_t j = 0; j < i; ++ j) {
            if(n + j < rand_num[j]) {
                n_where = j;
                break;
            }
        }
        // see where it should be inserted

        rand_num.insert(rand_num.begin() + n_where, 1, n + n_where);
        // insert it in the list, maintain a sorted sequence
    }
    // tier 1 - use comparison with offset instead of increment
}

Where n_select_num is your 5 and n_number_num is your MAX. The n_Rand(x) returns random integers in [0, x] (inclusive). This can be made a bit faster if selecting a lot of items (e.g. not 5 but 500) by using binary search to find the insertion point. To do that, we need to make sure that we meet the requirements.

We will do binary search with the comparison n + j < rand_num[j] which is the same as
n < rand_num[j] - j. We need to show that rand_num[j] - j is still a sorted sequence for a sorted sequence rand_num[j]. This is fortunately easily shown, as the lowest distance between two elements of the original rand_num is one (the generated numbers are unique, so there is always difference of at least 1). At the same time, if we subtract the indices j from all the elements
rand_num[j], the differences in index are exactly 1. So in the "worst" case, we get a constant sequence - but never decreasing. The binary search can therefore be used, yielding O(n log(n)) algorithm:

struct TNeedle { // in the comparison operator we need to make clear which argument is the needle and which is already in the list; we do that using the type system.
    int n;

    TNeedle(int _n)
        :n(_n)
    {}
};

class CCompareWithOffset { // custom comparison "n < rand_num[j] - j"
protected:
    std::vector<int>::iterator m_p_begin_it;

public:
    CCompareWithOffset(std::vector<int>::iterator p_begin_it)
        :m_p_begin_it(p_begin_it)
    {}

    bool operator ()(const int &r_value, TNeedle n) const
    {
        size_t n_index = &r_value - &*m_p_begin_it;
        // calculate index in the array

        return r_value < n.n + n_index; // or r_value - n_index < n.n
    }

    bool operator ()(TNeedle n, const int &r_value) const
    {
        size_t n_index = &r_value - &*m_p_begin_it;
        // calculate index in the array

        return n.n + n_index < r_value; // or n.n < r_value - n_index
    }
};

And finally:

void RandomUniqueSequence(std::vector<int> &rand_num,
    const size_t n_select_num, const size_t n_item_num)
{
    assert(n_select_num <= n_item_num);

    rand_num.clear(); // !!

    // b1: 3578.000 msec
    // b2: 1703.000 msec (the fastest)
    for(size_t i = 0; i < n_select_num; ++ i) {
        int n = n_Rand(n_item_num - i - 1);
        // get a random number

        std::vector<int>::iterator p_where_it = std::upper_bound(rand_num.begin(), rand_num.end(),
            TNeedle(n), CCompareWithOffset(rand_num.begin()));
        // see where it should be inserted

        rand_num.insert(p_where_it, 1, n + p_where_it - rand_num.begin());
        // insert it in the list, maintain a sorted sequence
    }
    // tier 4 - use binary search
}

I have tested this on three benchmarks. First, 3 numbers were chosen out of 7 items, and a histogram of the items chosen was accumulated over 10,000 runs:

4265 4229 4351 4267 4267 4364 4257

This shows that each of the 7 items was chosen approximately the same number of times, and there is no apparent bias caused by the algorithm. All the sequences were also checked for correctness (uniqueness of contents).

The second benchmark involved choosing 7 numbers out of 5000 items. The time of several versions of the algorithm was accumulated over 10,000,000 runs. The results are denoted in comments in the code as b1. The simple version of the algorithm is slightly faster.

The third benchmark involved choosing 700 numbers out of 5000 items. The time of several versions of the algorithm was again accumulated, this time over 10,000 runs. The results are denoted in comments in the code as b2. The binary search version of the algorithm is now more than two times faster than the simple one.

The second method starts being faster for choosing more than cca 75 items on my machine (note that the complexity of either algorithm does not depend on the number of items, MAX).

It is worth mentioning that the above algorithms generate the random numbers in ascending order. But it would be simple to add another array to which the numbers would be saved in the order in which they were generated, and returning that instead (at negligible additional cost O(n)). It is not necessary to shuffle the output: that would be much slower.

Note that the sources are in C++, I don't have Java on my machine, but the concept should be clear.

EDIT:

For amusement, I have also implemented the approach that generates a list with all the indices
0 .. MAX, chooses them randomly and removes them from the list to guarantee uniqueness. Since I've chosen quite high MAX (5000), the performance is catastrophic:

// b1: 519515.000 msec
// b2: 20312.000 msec
std::vector<int> all_numbers(n_item_num);
std::iota(all_numbers.begin(), all_numbers.end(), 0);
// generate all the numbers

for(size_t i = 0; i < n_number_num; ++ i) {
    assert(all_numbers.size() == n_item_num - i);
    int n = n_Rand(n_item_num - i - 1);
    // get a random number

    rand_num.push_back(all_numbers[n]); // put it in the output list
    all_numbers.erase(all_numbers.begin() + n); // erase it from the input
}
// generate random numbers

I have also implemented the approach with a set (a C++ collection), which actually comes second on benchmark b2, being only about 50% slower than the approach with the binary search. That is understandable, as the set uses a binary tree, where the insertion cost is similar to binary search. The only difference is the chance of getting duplicate items, which slows down the progress.

// b1: 20250.000 msec
// b2: 2296.000 msec
std::set<int> numbers;
while(numbers.size() < n_number_num)
    numbers.insert(n_Rand(n_item_num - 1)); // might have duplicates here
// generate unique random numbers

rand_num.resize(numbers.size());
std::copy(numbers.begin(), numbers.end(), rand_num.begin());
// copy the numbers from a set to a vector

The 3 easiest ways IMHO are

1: you create an image of a button and put a href around it. (Not a good way, you lose flexibility and will provide a lot of difficulties and problems.)

2 (The easiest one) -> JQuery

<input type="submit" someattribute="http://yoururl/index.php">

  $('button[type=submit] .default').click(function(){
     window.location = $(this).attr("someattribute");
     return false; //otherwise it will send a button submit to the server

   });  

3 (also easy but I prefer previous one):

<INPUT TYPE=BUTTON OnClick="somefunction("http://yoururl");return false" VALUE="somevalue">

$fn.somefunction= function(url) {
    window.location = url;
};

This answer is simpler than my answer: https://stackoverflow.com/a/21718540/541862

Original answer:

# Create a backup of master branch
git branch backup_master

# Point master to '56e05fce' and
# make working directory the same with '56e05fce'
git reset --hard 56e05fce

# Point master back to 'backup_master' and
# leave working directory the same with '56e05fce'.
git reset --soft backup_master

# Now working directory is the same '56e05fce' and
# master points to the original revision. Then we create a commit.
git commit -a -m "Revert to 56e05fce"

# Delete unused branch
git branch -d backup_master

The two commands git reset --hard and git reset --soft are magic here. The first one changes the working directory, but it also changes head (the current branch) too. We fix the head by the second one.

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null, though, otherwise it acts like new DateTime() - I really don't like that.

Working example. Notes below.

class Animal {
    constructor(public name) {
    }

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    move() {
        alert(this.name + " is Slithering...");
        super.move(5);
    }
}

class Horse extends Animal {
    move() {
        alert(this.name + " is Galloping...");
        super.move(45);
    }
}

var sam = new Snake("Sammy the Python");
var tom: Animal = new Horse("Tommy the Palomino");

sam.move();
tom.move(34);

1. You don't need to manually assign the name to a public variable. Using public name in the constructor definition does this for you.

2. You don't need to call super(name) from the specialised classes.

3. Using this.name works.

Notes on use of super.

This is covered in more detail in section 4.9.2 of the language specification.

The behaviour of the classes inheriting from Animal is not dissimilar to the behaviour in other languages. You need to specify the super keyword in order to avoid confusion between a specialised function and the base class function. For example, if you called move() or this.move() you would be dealing with the specialised Snake or Horse function, so using super.move() explicitly calls the base class function.

There is no confusion of properties, as they are the properties of the instance. There is no difference between super.name and this.name - there is simply this.name. Otherwise you could create a Horse that had different names depending on whether you were in the specialized class or the base class.

The default, unnamed instance always gets port 1433 for TCP. UDP port 1434 is used by the SQL Browser service to allow named instances to be located. In SQL Server 2000 the first instance to be started took this role.

Non-default instances get their own dynamically-allocated port, by default. If necessary, for example to configure a firewall, you can set them explicitly. If you don't want to enable or allow access to SQL Browser, you have to either include the instance's port number in the connection string, or set it up with the Alias tab in cliconfg (SQL Server Client Network Utility) on each client machine.

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. By the way,ini_set() helps you to change the values in php.ini during run time.

This is the same question as Failed to connect to mailserver at "localhost" port 25

You should also take a look at svgweb. It uses flash to render svg in IE, and optionally on other browsers (in the cases where it supports more than the browser itself does).

According to this discussion, Promise has finally been called CompletableFuture for inclusion in Java 8, and its javadoc explains:

A Future that may be explicitly completed (setting its value and status), and may be used as a CompletionStage, supporting dependent functions and actions that trigger upon its completion.

An example is also given on the list:

f.then((s -> aStringFunction(s)).thenAsync(s -> ...);

Note that the final API is slightly different but allows similar asynchronous execution:

CompletableFuture<String> f = ...;
f.thenApply(this::modifyString).thenAccept(System.out::println);

You only need one INSERT:

INSERT INTO table4 ( name, age, sex, city, id, number, nationality)
SELECT name, age, sex, city, p.id, number, n.nationality
FROM table1 p
INNER JOIN table2 c ON c.Id = p.Id
INNER JOIN table3 n ON p.Id = n.Id

The following code will fail:

List<String> will_fail =  (List<String>)Collections.unmodifiableCollection(new ArrayList<String>());

This instead will work:

List<String> will_work = new ArrayList<String>(Collections.unmodifiableCollection(new ArrayList<String>()));

You could try this more generic function:

function from12to24(hours, minutes, meridian) {
  let h = parseInt(hours, 10);
  const m = parseInt(minutes, 10);
  if (meridian.toUpperCase() === 'PM') {
    h = (h !== 12) ? h + 12 : h;
  } else {
    h = (h === 12) ? 0 : h;
  }
  return new Date((new Date()).setHours(h,m,0,0));
}   

Note it uses some ES6 functionality.

For your question as asked

Columns(3).Insert
Range("c1:c4") = Application.Transpose(Array("Loc", "uk", "us", "nj"))

If you had a way of automatically looking up the data (ie matching uk against employer id) then you could do that in VBA

if(!preg_match('/^[\w-]+$/', $string1)) {
   echo "String 1 not acceptable acceptable";
   // String2 acceptable
}

SELECT COLUMN_NAME 'all_columns' 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_NAME='user';

It is possible to access the variables with process.env.blabla instead of process.env['blabla']. I recently made it work and commented on how I did it on an issue on GitHub because I had some problems with cache based on the accepted answer. Here is the issue.

To update a subset of fields, you can use update_fields:

survey.save(update_fields=["active"]) 

The update_fields argument was added in Django 1.5. In earlier versions, you could use the update() method instead:

Survey.objects.filter(pk=survey.pk).update(active=True)

You can combine selectors like this

$(".alert-box.warn, .alert-box.dead");

Or if you want a wildcard use the attribute-contains selector

$("[class*='alert-box']");

Note: Preferably you would know the element type or tag when using the selectors above. Knowing the tag can make the selector more efficient.

$("div.alert-box.warn, div.alert-box.dead");
$("div[class*='alert-box']");

If the name column were a JSON array (like '["a","b","c"]'), then you could extract/unpack it with JSON_TABLE() (available since MySQL 8.0.4):

select t.id, j.name
from mytable t
join json_table(
  t.name,
  '$[*]' columns (name varchar(50) path '$')
) j;

Result:

| id  | name |
| --- | ---- |
| 1   | a    |
| 1   | b    |
| 1   | c    |
| 2   | b    |

If you store the values in a simple CSV format, then you would first need to convert it to JSON:

select t.id, j.name
from mytable t
join json_table(
  replace(json_array(t.name), ',', '","'),
  '$[*]' columns (name varchar(50) path '$')
) j

Result:

| id  | name |
| --- | ---- |
| 1   | a    |
| 1   | b    |
| 1   | c    |
| 2   | b    |

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

Most answers here are not correct as they would add bottom space to the last <li> as well, so they are not adding space ONLY in between <li> !

The most accurate and efficient solution is the following:

li.menu-item:not(:last-child) { 
   margin-bottom: 3px;  
}

Explanation: by using :not(:last-child) the style will be applie to all items (li.menu-item) but the last one.

I consider the easiest way is to refer to this Resource file: https://android.googlesource.com/platform/libcore/+/master/luni/src/main/java/libcore/net/android.mime.types

For me, the issue was the wrong directory. Make sure you copy paste the directory from your file explorer and not assume the directory specified on the docs page correct.

I believe the correct answer is actually a combination of both approaches: viewWIllTransition(toSize:) and NotificationCenter's UIDeviceOrientationDidChange.

viewWillTransition(toSize:) notifies you before the transition.

NotificationCenter UIDeviceOrientationDidChange notifies you after.

You have to be very careful. For example, in UISplitViewController when the device rotates into certain orientations, the DetailViewController gets popped off the UISplitViewController's viewcontrollers array, and pushed onto the master's UINavigationController. If you go searching for the detail view controller before the rotation has finished, it may not exist and crash.

You do know that DataRow is the row of a DataTable correct?

What you currently have already loop through each row. You just have to keep track of how many rows there are in order to get the current row.

int i = 0;
int index = 0;
foreach (DataRow row in dt.Rows) 
{
index = i;
// do stuff
i++;
} 

I have solved a similar problem by first importing the text into an excel spreadsheet, then using the Substitute function to replace both the single and double quotes as required by SQL Server, eg. SUBSTITUTE(SUBSTITUTE(A1, "'", "''"), """", "\""")

In my case, I had many rows (each a line of data to be cleaned then inserted) and had the spreadsheet automatically generate insert queries for the text once the substitution had been done eg. ="INSERT INTO [dbo].[tablename] ([textcolumn]) VALUES ('" & SUBSTITUTE(SUBSTITUTE(A1, "'", "''"), """", "\""") & "')"

I hope that helps.

You can put an apostrophe in a single quoted JavaScript string by escaping it with a backslash, like so:

theAnchorText = 'I\'m home';

So as I understand it { get; set; } is an "auto property" which just like @Klaus and @Brandon said is shorthand for writing a property with a "backing field." So in this case:

public class Genre
{
    private string name; // This is the backing field
    public string Name   // This is your property
    {
        get => name;
        set => name = value;
    }
}

However if you're like me - about an hour or so ago - you don't really understand what properties and accessors are, and you don't have the best understanding of some basic terminologies either. MSDN is a great tool for learning stuff like this but it's not always easy to understand for beginners. So I'm gonna try to explain this more in-depth here.

get and set are accessors, meaning they're able to access data and info in private fields (usually from a backing field) and usually do so from public properties (as you can see in the above example).

There's no denying that the above statement is pretty confusing, so let's go into some examples. Let's say this code is referring to genres of music. So within the class Genre, we're going to want different genres of music. Let's say we want to have 3 genres: Hip Hop, Rock, and Country. To do this we would use the name of the Class to create new instances of that class.

Genre g1 = new Genre(); //Here we're creating a new instance of the class "Genre"
                        //called g1. We'll create as many as we need (3)
Genre g2 = new Genre();
Genre g3 = new Genre();

//Note the () following new Genre. I believe that's essential since we're creating a
//new instance of a class (Like I said, I'm a beginner so I can't tell you exactly why
//it's there but I do know it's essential)

Now that we've created the instances of the Genre class we can set the genre names using the 'Name' property that was set way up above.

public string Name //Again, this is the 'Name' property
{ get; set; } //And this is the shorthand version the process we're doing right now 

We can set the name of 'g1' to Hip Hop by writing the following

g1.Name = "Hip Hop";

What's happening here is sort of complex. Like I said before, get and set access information from private fields that you otherwise wouldn't be able to access. get can only read information from that private field and return it. set can only write information in that private field. But by having a property with both get and set we're able do both of those functions. And by writing g1.Name = "Hip Hop"; we are specifically using the set function from our Name property

set uses an implicit variable called value. Basically what this means is any time you see "value" within set, it's referring to a variable; the "value" variable. When we write g1.Name = we're using the = to pass in the value variable which in this case is "Hip Hop". So you can essentially think of it like this:

public class g1 //We've created an instance of the Genre Class called "g1"
{
    private string name;
    public string Name
    {
        get => name;
        set => name = "Hip Hop"; //instead of 'value', "Hip Hop" is written because 
                              //'value' in 'g1' was set to "Hip Hop" by previously
                              //writing 'g1.Name = "Hip Hop"'
    }
}

It's Important to note that the above example isn't actually written in the code. It's more of a hypothetical code that represents what's going on in the background.

So now that we've set the Name of the g1 instance of Genre, I believe we can get the name by writing

console.WriteLine (g1.Name); //This uses the 'get' function from our 'Name' Property 
                             //and returns the field 'name' which we just set to
                             //"Hip Hop"

and if we ran this we would get "Hip Hop" in our console.

So for the purpose of this explanation I'll complete the example with outputs as well

using System;
public class Genre
{
    public string Name { get; set; }
}

public class MainClass
{
    public static void Main()
    {
        Genre g1 = new Genre();
        Genre g2 = new Genre();
        Genre g3 = new Genre();

        g1.Name = "Hip Hop";
        g2.Name = "Rock";
        g3.Name = "Country";

        Console.WriteLine ("Genres: {0}, {1}, {2}", g1.Name, g2.Name, g3.Name);
    }
}

Output:

"Genres: Hip Hop, Rock, Country"

A super key of an entity set is a set of one or more attributes whose values uniquely determine each entity.

A candidate key of an entity set is a minimal super key.

Let's go on with customer, loan and borrower sets that you can find an image from the link == 1

• Rectangles represent entity sets == 1
• Diamonds represent relationship set == 1
• Elipses represent attributes == 1
• Underline indicates Primary Keys == 1

customer_id is the candidate key of the customer set, loan_number is the candidate key of the loan set.

Although several candidate keys may exist, one of the candidate keys is selected to be the primary key.

Borrower set is formed customer_id and loan_number as a relationship set.

Although the following line is taken from a windows batch script, the command should be quite similar:

psql -U username -h localhost -d postgres -c "DROP DATABASE \"$DATABASE\";"

This command is used to clear the whole database, by actually dropping it. The $DATABASE (in Windows should be %DATABASE%) in the command is a windows style environment variable that evaluates to the database name. You will need to substitute that by your development_db_name.

Use:

function random_color(format)
{
    var rint = Math.round(0xffffff * Math.random());
    switch(format)
    {
        case 'hex':
            return ('#0' + rint.toString(16)).replace(/^#0([0-9a-f]{6})$/i, '#$1');
            break;

        case 'rgb':
            return 'rgb(' + (rint >> 16) + ',' + (rint >> 8 & 255) + ',' + (rint & 255) + ')';
            break;

        default:
            return rint;
            break;
    }
}

Updated version:

function random_color( format ){
  var rint = Math.floor( 0x100000000 * Math.random());
  switch( format ){
    case 'hex':
      return '#' + ('00000'   + rint.toString(16)).slice(-6).toUpperCase();
    case 'hexa':
      return '#' + ('0000000' + rint.toString(16)).slice(-8).toUpperCase();
    case 'rgb':
      return 'rgb('  + (rint & 255) + ',' + (rint >> 8 & 255) + ',' + (rint >> 16 & 255) + ')';
    case 'rgba':
      return 'rgba(' + (rint & 255) + ',' + (rint >> 8 & 255) + ',' + (rint >> 16 & 255) + ',' + (rint >> 24 & 255)/255 + ')';
    default:
      return rint;
  }
}

I think the example is wrong - javax.sql.DataSource doesn't have these properties either. Your DataSource needs to be of the type org.apache.derby.jdbc.ClientDataSource, which should have those properties.

A timestamp is a point in time. Typically this can be represented by a number of milliseconds past an epoc (the Unix Epoc of Jan 1 1970 12AM UTC). The format of that point in time depends on the time zone. While it is the same point in time, the "hours value" is not the same among time zones and one must take into account the offset from the UTC.

Here's some code to illustrate. A point is time is captured in three different ways.

var moment = require( 'moment' );

var localDate = new Date();
var localMoment = moment();
var utcMoment = moment.utc();
var utcDate = new Date( utcMoment.format() );

//These are all the same
console.log( 'localData unix = ' + localDate.valueOf() );
console.log( 'localMoment unix = ' + localMoment.valueOf() );
console.log( 'utcMoment unix = ' + utcMoment.valueOf() );

//These formats are different
console.log( 'localDate = ' + localDate );
console.log( 'localMoment string = ' + localMoment.format() );
console.log( 'utcMoment string = ' + utcMoment.format() );
console.log( 'utcDate  = ' + utcDate );

//One to show conversion
console.log( 'localDate as UTC format = ' + moment.utc( localDate ).format() );
console.log( 'localDate as UTC unix = ' + moment.utc( localDate ).valueOf() );

Which outputs this:

localData unix = 1415806206570
localMoment unix = 1415806206570
utcMoment unix = 1415806206570
localDate = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localMoment string = 2014-11-12T10:30:06-05:00
utcMoment string = 2014-11-12T15:30:06+00:00
utcDate  = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localDate as UTC format = 2014-11-12T15:30:06+00:00
localDate as UTC unix = 1415806206570

In terms of milliseconds, each are the same. It is the exact same point in time (though in some runs, the later millisecond is one higher).

As far as format, each can be represented in a particular timezone. And the formatting of that timezone'd string looks different, for the exact same point in time!

Are you going to compare these time values? Just convert to milliseconds. One value of milliseconds is always less than, equal to or greater than another millisecond value.

Do you want to compare specific 'hour' or 'day' values and worried they "came from" different timezones? Convert to UTC first using moment.utc( existingDate ), and then do operations. Examples of those conversions, when coming out of the DB, are the last console.log calls in the example.

Just be warned - When using a Nullable its obviously no longer a 'pure' datetime object, as such you cannot access the DateTime members directly. I'll try and explain.

By using Nullable<> you're basically wrapping DateTime in a container (thank you generics) of which is nullable - obviously its purpose. This container has its own properties which you can call that will provide access to the aforementioned DateTime object; after using the correct property - in this case Nullable.Value - you then have access to the standard DateTime members, properties etc.

So - now the issue comes to mind as to the best way to access the DateTime object. There are a few ways, number 1 is by FAR the best and 2 is "dude why".

1. Using the Nullable.Value property,

   DateTime date = myNullableObject.Value.ToUniversalTime(); //Works

   DateTime date = myNullableObject.ToUniversalTime(); //Not a datetime object, fails

2. Converting the nullable object to datetime using Convert.ToDateTime(),

   DateTime date = Convert.ToDateTime(myNullableObject).ToUniversalTime(); //works but why...

Although the answer is well documented at this point, I believe the usage of Nullable was probably worth posting about. Sorry if you disagree.

edit: Removed a third option as it was a bit overly specific and case dependent.

When running the python file, you would normally do this

python app.py

To avoid these messsages. Inside the CLI (Command Line Interface), run these commands.

export FLASK_ENV=development
export FLASK_DEBUG=0
