This is usually due to missing, incorrect or duplicated Service Principle Names (SPNs)

Steps to resolve:

1. Confirm what AD account SQL Server is using
2. Run the following command in Powershell or CMD in administrator mode (service account should not contain the domain)

setspn -L <ServiceAccountName> | Select-String <ServerName> | select line

3. Make sure the returned output contains an SPN which is fully qualified, no fully qualified, with a port and without a port.

   Expected Output:

   Registered ServicePrincipalNames for CN=<ServiceAccountName>,OU=CSN Service Accounts,DC=<Domain>,DC=com: 
   MSSQLSvc/<ServerName>.<domain>.com:1433
   MSSQLSvc/<ServerName>:1433                                           
   MSSQLSvc/<ServerName>.<domain>.com
   MSSQLSvc/<ServerName>
   

4. If you don't see all of the above, run the following command in PowerShell or CMD in admin mode (make sure to change the port if you don't use default 1433)

SETSPN -S  MSSQLSvc/<ServerName> <Domain>\<ServiceAccountName> 
SETSPN -S  MSSQLSvc/<ServerName>.<Domain> <Domain>\<ServiceAccountName> 
SETSPN -S  MSSQLSvc/<ServerName>:1433 <Domain>\<ServiceAccountName> 
SETSPN -S  MSSQLSvc/<ServerName>.<Domain>:1433 <Domain>\<ServiceAccountName>

5. Once above is complete it normally takes a few minutes for DNS propagation

Also, if you get a message about duplicate SPNs found, you may want to delete them and recreate them

I recently set up a script that does this.

As David Brabant pointed out, you can use the System.Net.WebRequest class to do an HTTP request.

To check whether it is operational, you should use the following example code:

# First we create the request.
$HTTP_Request = [System.Net.WebRequest]::Create('http://google.com')

# We then get a response from the site.
$HTTP_Response = $HTTP_Request.GetResponse()

# We then get the HTTP code as an integer.
$HTTP_Status = [int]$HTTP_Response.StatusCode

If ($HTTP_Status -eq 200) {
    Write-Host "Site is OK!"
}
Else {
    Write-Host "The Site may be down, please check!"
}

# Finally, we clean up the http request by closing it.
If ($HTTP_Response -eq $null) { } 
Else { $HTTP_Response.Close() }

Had similar problems recently. Would suggest you carefully check if the user you're connecting with has proper authorizations on the remote machine.

You can review permissions using the following command.

Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell

Found this tip here (updated link, thanks "unbob"):

https://devblogs.microsoft.com/scripting/configure-remote-security-settings-for-windows-powershell/

It fixed it for me.

Just access the Priority property of the object returned from the pipeline:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

(This won't work if Get-WSManInstance returns multiple objects.²)

For the second question: to get two properties there are several options, problably the simplest is to have have one variable* containing an object with two separate properties:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use, assuming only one process:

$var.Priority

and

$var.ProcessID

If there are multiple processes $var will be an array which you can index, so to get the properties of the first process (using the array literal syntax @(...) so it is always a collection¹):

$var = @(Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use:

$var[0].Priority
$var[0].ProcessID

¹ PowerShell helpfully for the command line, but not so helpfully in scripts has some extra logic when assigning the result of a pipeline to a variable: if no objects are returned then set $null, if one is returned then that object is assigned, otherwise an array is assigned. Forcing an array returns an array with zero, one or more (respectively) elements.

² This changes in PowerShell V3 (at the time of writing in Release Candidate), using a member property on an array of objects will return an array of the value of those properties.

Try doing this:

Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force

Try like this

String sql = "SELECT t FROM table t";
Query query = em.createQuery(sql);
query.setFirstResult(firstPosition);
query.setMaxResults(numberOfRecords);
List result = query.getResultList();

It should work

UPDATE*

You can also try like this

query.setMaxResults(1).getResultList();

The expression *src refers to the first character in the string, not the whole string. To reassign src to point to a different string tgt, use src = tgt;.

Here's another way to force a type-cast even between incompatible types and interfaces where TS compiler normally complains:

export function forceCast<T>(input: any): T {

  // ... do runtime checks here

  // @ts-ignore <-- forces TS compiler to compile this as-is
  return input;
}

Then you can use it to force cast objects to a certain type:

import { forceCast } from './forceCast';

const randomObject: any = {};
const typedObject = forceCast<IToDoDto>(randomObject);

Note that I left out the part you are supposed to do runtime checks before casting for the sake of reducing complexity. What I do in my project is compiling all my .d.ts interface files into JSON schemas and using ajv to validate in runtime.

This code work for me:

    BufferedImage image = null;
    try {
        URL file = getClass().getResource("water.bmp");
        image = ImageIO.read(file);
    } catch (IOException ioex) {
        System.err.println("load error: " + ioex.getMessage());
    }
    ImageIcon icon = new ImageIcon(image);
    JButton quitButton = new JButton(icon);

The most important thing is add tzinfo when you define a datetime object.

from datetime import datetime, timezone
from tzinfo_examples import HOUR, Eastern
u0 = datetime(2016, 3, 13, 5, tzinfo=timezone.utc)
for i in range(4):
     u = u0 + i*HOUR
     t = u.astimezone(Eastern)
     print(u.time(), 'UTC =', t.time(), t.tzname())

In most cases, using __dict__ or dir() will get you the info you're wanting. If you should happen to need more details, the standard library includes the inspect module, which allows you to get some impressive amount of detail. Some of the real nuggests of info include:

• names of function and method parameters
• class hierarchies
• source code of the implementation of a functions/class objects
• local variables out of a frame object

If you're just looking for "what attribute values does my object have?", then dir() and __dict__ are probably sufficient. If you're really looking to dig into the current state of arbitrary objects (keeping in mind that in python almost everything is an object), then inspect is worthy of consideration.

Without Virtual Environments

pip <command> --user changes the scope of the current pip command to work on the current user account's local python package install location, rather than the system-wide package install location, which is the default.

• See User Installs in the PIP User Guide.

This only really matters on a multi-user machine. Anything installed to the system location will be visible to all users, so installing to the user location will keep that package installation separate from other users (they will not see it, and would have to install it themselves separately to use it). Because there can be version conflicts, installing a package with dependencies needed by other packages can cause problems, so it's best not to push all packages a given user uses to the system install location.

• If it is a single-user machine, there is little or no difference to installing to the --user location. It will be installed to a different folder, that may or may not need to be added to the path, depending on the package and how it's used (many packages install command-line tools that must be on the path to run from a shell).
• If it is a multi-user machine, --user is preferred to using root/sudo or requiring administrator installation and affecting the Python environment of every user, except in cases of general packages that the administrator wants to make available to all users by default.
  • Note: Per comments, on most Unix/Linux installs it has been pointed out that system installs should use the general package manager, such as apt, rather than pip.

With Virtual Environments

• See more about installing packages with virtual environments in the Python Packaging documentation.
• Read about how to create and use virtual environments, and the venv command in the Python VENV docs.

The --user option in an active venv/virtualenv environment will install to the local user python location (same as without a virtual environment).

Packages are installed to the virtual environment by default, but if you use --user it will force it to install outside the virtual environments, in the users python script directory (in Windows, this currently is c:\users\<username>\appdata\roaming\python\python37\scripts for me with Python 3.7).

However, you won't be able to access a system or user install from within virtual environment (even if you used --user while in a virtual environment).

If you install a virtual environment with the --system-site-packages argument, you will have access to the system script folder for python. I believe this included the user python script folder as well, but I'm unsure. However, there may be unintended consequences for this and it is not the intended way to use virtual environments.

Location of the Python System and Local User Install Folders

You can find the location of the user install folder for python with python -m site --user-base. I'm finding conflicting information in Q&A's, the documentation and actually using this command on my PC as to what the defaults are, but they are underneath the user home directory (~ shortcut in *nix, and c:\users\<username> typically for Windows).

Other Details

The --user option is not a valid for every command. For example pip uninstall will find and uninstall packages wherever they were installed (in the user folder, virtual environment folder, etc.) and the --user option is not valid.

Things installed with pip install --user will be installed in a local location that will only be seen by the current user account, and will not require root access (on *nix) or administrator access (on Windows).

The --user option modifies all pip commands that accept it to see/operate on the user install folder, so if you use pip list --user it will only show you packages installed with pip install --user.

This worked for me (i wanted to make id primary and set auto increment)

ALTER TABLE table_name CHANGE id id INT PRIMARY KEY AUTO_INCREMENT;

Use aspnet_regiis.exe to register version of .NET framework you are using.

This is a common issue and happens when IIS is installed after VS or .NET framework.

Note - for Windows 8/10 users, see the other answer by JohnOpincar below. And also the comment/tip from Kevin Brydon.

Declare int array at global

var numbers= intArrayOf()

next onCreate method initialize your array with value

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    //create your int array here
    numbers= intArrayOf(10,20,30,40,50)
}

Use Apache HttpComponents and wire it up with some collection code to access params by value: http://www.joelgerard.com/2012/09/14/parsing-query-strings-in-java-and-accessing-values-by-key/

Try the code below, using jQuery extend method:

var json1 = {"name":"ramesh","age":"12"};

var json2 = {"member":"true"};

document.write(JSON.stringify($.extend(true,{},json1,json2)))

<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>

That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em' as the measurement, you may want to use other units, like 'px'.

EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:

In your HTML page, containing the <p> tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:

<head>
  <style type="text/css">
    p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>

So above, all <p> elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:

<head>
  <style type="text/css">
    .container p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <div class="container">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
  </div>
  <p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>

In the example above, only the <p> element inside the div, whose class name is 'container', will have the styles applied - and not the <p> element outside the container.

In addition to the above, you can collect your styles together and remove the style element from the <head> tag, replacing it with a <link> tag, which points to an external CSS file. This external file is where you'd now put your <p> tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.

The local names for a function are decided when the function is defined:

>>> x = 1
>>> def inc():
...     x += 5
...     
>>> inc.__code__.co_varnames
('x',)

In this case, x exists in the local namespace. Execution of x += 5 requires a pre-existing value for x (for integers, it's like x = x + 5), and this fails at function call time because the local name is unbound - which is precisely why the exception UnboundLocalError is named as such.

Compare the other version, where x is not a local variable, so it can be resolved at the global scope instead:

>>> def incg():
...    print(x)
...    
>>> incg.__code__.co_varnames
()

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

vector<string> split(string str, string token){
    vector<string>result;
    while(str.size()){
        int index = str.find(token);
        if(index!=string::npos){
            result.push_back(str.substr(0,index));
            str = str.substr(index+token.size());
            if(str.size()==0)result.push_back(str);
        }else{
            result.push_back(str);
            str = "";
        }
    }
    return result;
}

split("1,2,3",",") ==> ["1","2","3"]

split("1,2,",",") ==> ["1","2",""]

split("1token2token3","token") ==> ["1","2","3"]

Interesting, I didn't know make would default to using the C compiler given rules regarding source files.

Anyway, a simple solution that demonstrates simple Makefile concepts would be:

HEADERS = program.h headers.h

default: program

program.o: program.c $(HEADERS)
    gcc -c program.c -o program.o

program: program.o
    gcc program.o -o program

clean:
    -rm -f program.o
    -rm -f program

(bear in mind that make requires tab instead of space indentation, so be sure to fix that when copying)

However, to support more C files, you'd have to make new rules for each of them. Thus, to improve:

HEADERS = program.h headers.h
OBJECTS = program.o

default: program

%.o: %.c $(HEADERS)
    gcc -c $< -o $@

program: $(OBJECTS)
    gcc $(OBJECTS) -o $@

clean:
    -rm -f $(OBJECTS)
    -rm -f program

I tried to make this as simple as possible by omitting variables like $(CC) and $(CFLAGS) that are usually seen in makefiles. If you're interested in figuring that out, I hope I've given you a good start on that.

Here's the Makefile I like to use for C source. Feel free to use it:

TARGET = prog
LIBS = -lm
CC = gcc
CFLAGS = -g -Wall

.PHONY: default all clean

default: $(TARGET)
all: default

OBJECTS = $(patsubst %.c, %.o, $(wildcard *.c))
HEADERS = $(wildcard *.h)

%.o: %.c $(HEADERS)
    $(CC) $(CFLAGS) -c $< -o $@

.PRECIOUS: $(TARGET) $(OBJECTS)

$(TARGET): $(OBJECTS)
    $(CC) $(OBJECTS) -Wall $(LIBS) -o $@

clean:
    -rm -f *.o
    -rm -f $(TARGET)

It uses the wildcard and patsubst features of the make utility to automatically include .c and .h files in the current directory, meaning when you add new code files to your directory, you won't have to update the Makefile. However, if you want to change the name of the generated executable, libraries, or compiler flags, you can just modify the variables.

In either case, don't use autoconf, please. I'm begging you! :)

The following steps can be used:

sudo apt-get -y update

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

You can access a non-Native HashTable through System.Collections.HashTable.

HashTable

Represents a collection of key/value pairs that are organized based on the hash code of the key.

Not sure you would ever want to use this over Scripting.Dictionary but adding here for the sake of completeness. You can review the methods in case there are some of interest e.g. Clone, CopyTo

Example:

Option Explicit

Public Sub UsingHashTable()

    Dim h As Object
    Set h = CreateObject("System.Collections.HashTable")
   
    h.Add "A", 1
    ' h.Add "A", 1  ''<< Will throw duplicate key error
    h.Add "B", 2
    h("B") = 2
      
    Dim keys As mscorlib.IEnumerable 'Need to cast in order to enumerate  'https://stackoverflow.com/a/56705428/6241235
    
    Set keys = h.keys
    
    Dim k As Variant
    
    For Each k In keys
        Debug.Print k, h(k)                      'outputs the key and its associated value
    Next
    
End Sub

This answer by @MathieuGuindon gives plenty of detail about HashTable and also why it is necessary to use mscorlib.IEnumerable (early bound reference to mscorlib) in order to enumerate the key:value pairs.

If you really need True or False, just use bool

>>> bool(re.search("hi", "abcdefghijkl"))
True
>>> bool(re.search("hi", "abcdefgijkl"))
False

As other answers have pointed out, if you are just using it as a condition for an if or while, you can use it directly without wrapping in bool()

Here's a Django logging-based solution. It uses the DEBUG setting rather than actually checking whether or not you're running the development server, but if you find a better way to check for that it should be easy to adapt.

Create an xml file named roundedbutton.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="rectangle">
    <solid android:color="#eeffffff" />
    <corners android:bottomRightRadius="8dp"
        android:bottomLeftRadius="8dp"  
        android:topRightRadius="8dp"
        android:topLeftRadius="8dp"/>
</shape>

Finally set that as background to your Button as android:background = "@drawable/roundedbutton"

If you want to make it completely rounded, alter the radius and settle for something that is ok for you.

Use Int64 instead of Int. Int64 can store large int values.

Running your code through a Javascript static analysis tool like JSLint can catch some common IE7 errors, such as trailing commas in object definitions.

If your having .so file in armeabi then mention inside ndk that folder alone.

defaultConfig {
        applicationId "com.xxx.yyy"
        minSdkVersion 17

        versionCode 1
        versionName "1.0"
        renderscriptTargetApi 26
        renderscriptSupportModeEnabled true
        ndk {
            abiFilters "armeabi"
        }
    }

and then use this

android.useDeprecatedNdk=true;

in gradle.properties file

The accepted solution doesn't cover edge cases. I found the way to do this with 4KB script. Handle your input and convert a data.

Examples:

00:00:00 -> 00:00:00
12:01 -> 12:01:00
12 -> 12:00:00
25 -> 00:00:00
12:60:60 -> 12:00:00
1dg46 -> 14:06

You got the idea... Check it https://github.com/alekspetrov/time-input-js

An entity manager can only be injected in classes running inside a transaction. In other words, it can only be injected in a EJB. Other classe must use an EntityManagerFactory to create and destroy an EntityManager.

Since your TestService is not an EJB, the annotation @PersistenceContext is simply ignored. Not only that, in JavaEE 5, it's not possible to inject an EntityManager nor an EntityManagerFactory in a JAX-RS Service. You have to go with a JavaEE 6 server (JBoss 6, Glassfish 3, etc).

Here's an example of injecting an EntityManagerFactory:

package com.test.service;

import java.util.*;
import javax.persistence.*;
import javax.ws.rs.*;

@Path("/service")
public class TestService {

    @PersistenceUnit(unitName = "test")
    private EntityManagerFactory entityManagerFactory;

    @GET
    @Path("/get")
    @Produces("application/json")
    public List get() {
        EntityManager entityManager = entityManagerFactory.createEntityManager();
        try {
            return entityManager.createQuery("from TestEntity").getResultList();
        } finally {
            entityManager.close();
        }
    }
}

The easiest way to go here is to declare your service as a EJB 3.1, assuming you're using a JavaEE 6 server.

In WPF, TextBox element will not get opportunity to use "Enter" button for creating KeyUp Event until you will not set property: AcceptsReturn="True".

But, it would`t solve the problem with handling KeyUp Event in TextBox element. After pressing "ENTER" you will get a new text line in TextBox.

I had solved problem of using KeyUp Event of TextBox element by using Bubble event strategy. It's short and easy. You have to attach a KeyUp Event handler in some (any) parent element:

<Window x:Class="TextBox_EnterButtomEvent.MainWindow"

            }
        }

Result:

You can use varargs

public function yourFunction(Parameter... parameters)

Agile is a general philosophy regarding software production, Scrum is an implementation of that philosophy pertaining specifically to project management.

Make sure the file is a recognized type. I had a yaml file open (without the .yaml file extension) and Sublime Text recognized it as Plain Text. Plain Text has no comment method. Switching the file type to YAML made the comment shortcut work.

Why the fuss?

replace(haystack, haystack %in% needles, replacements)

Demo:

haystack <- c("q", "w", "e", "r", "t", "y")
needles <- c("q", "w")
replacements <- c("a", "z")

replace(haystack, haystack %in% needles, replacements)
#> [1] "a" "z" "e" "r" "t" "y"

It's not very clear what the problem is and what you are trying to accomplish from the code you posted, but I'll take a stab at it.

In general, I suggest calling a function on ng-click like so:

<a ng-click="navigateToPath()">click me</a>

obj.val1 & obj.val2 should be available on your controller's $scope, you dont need to pass those into a function from the markup.

then, in your controller:

$scope.navigateToPath = function(){
   var path = '/somePath/' + $scope.obj.val1 + '/' + $scope.obj.val2; //dont need the '#'
   $location.path(path)       
}

Great answer from Anonymous. \ solved my problem when I tried to escape quotes in HTML strings.

So if you use sed to return some HTML templates (on a server), use double backslash instead of single:

var htmlTemplate = "<div style=\\"color:green;\\"></div>";

Use Link-1 to generate a project. this a basic project for learning. you can understand the folder structure. Use Link-2 for creating a basic Spring boot project. 1: http://start.spring.io/ 2: https://projects.spring.io/spring-boot/

I have a very simple working example of geting pixel color from canvas.

First some basic HTML:

<canvas id="myCanvas" width="400" height="250" style="background:red;" onmouseover="echoColor(event)">
</canvas>

Then JS to draw something on the Canvas, and to get color:

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.fillStyle = "black";
ctx.fillRect(10, 10, 50, 50);

function echoColor(e){
    var imgData = ctx.getImageData(e.pageX, e.pageX, 1, 1);
    red = imgData.data[0];
    green = imgData.data[1];
    blue = imgData.data[2];
    alpha = imgData.data[3];
    console.log(red + " " + green + " " + blue + " " + alpha);  
}

Here is a working example, just look at the console.

The graphicx package provides the command \resizebox{width}{height}{object}:

\settowidth{\@tempdimb}{(\ref{Equ:TooLong})}% the width of the "(1)"
\addtolength{\@tempdima}{-\the\@tempdimb}% which cannot be used for the math
\addtolength{\@tempdima}{-1em}%
% There is probably some variable giving the required minimal distance
% between math and label, but because I do not know it I used 1em instead.
\addtolength{\@tempdima}{-1pt}% distance must be greater than "1em"
\xdef\Equ@width{\the\@tempdima}% space remaining for math

Another solution to this problem is to simply change the property-> Build Action on the XAML from Embedded Resource to anything else, save, then change it right back to Embedded Resource. The error goes away.

You can try something like this:

$scope.test = "test1,test2";
{{test.split(',')[0]}}

now you will get "test1" while you try {{test.split(',')[0]}}

and you will get "test2" while you try {{test.split(',')[1]}}

here is my plnkr:

Use OnClientClick = "return false;"

Sass (Syntactically Awesome StyleSheets) have two syntaxes:

• a newer: SCSS (Sassy CSS)
• and an older, original: indent syntax, which is the original Sass and is also called Sass.

So they are both part of Sass preprocessor with two different possible syntaxes.

The most important difference between SCSS and original Sass:

SCSS:

• Syntax is similar to CSS (so much that every regular valid CSS3 is also valid SCSS, but the relationship in the other direction obviously does not happen)

• Uses braces {}

• Uses semi-colons ;
• Assignment sign is :
• To create a mixin it uses the @mixin directive
• To use mixin it precedes it with the @include directive
• Files have the .scss extension.

Original Sass:

• Syntax is similar to Ruby
• No braces
• No strict indentation
• No semi-colons
• Assignment sign is = instead of :
• To create a mixin it uses the = sign
• To use mixin it precedes it with the + sign
• Files have the .sass extension.

Some prefer Sass, the original syntax - while others prefer SCSS. Either way, but it is worth noting that Sass’s indented syntax has not been and will never be deprecated.

Conversions with sass-convert:

# Convert Sass to SCSS
$ sass-convert style.sass style.scss

# Convert SCSS to Sass
$ sass-convert style.scss style.sass

Depending on what kind of List you want to use, something like

List<String> supplierNames = new ArrayList<String>();

should get you going.

List is the interface, ArrayList is one implementation of the List interface. More implementations that may better suit your needs can be found by reading the JavaDocs of the List interface.

You can use WMI to figure this out. The Win32_BootConfiguration class will tell you both the logical drive and the physical device from which Windows boots. Specifically, the Caption property will tell you which device you're booting from.

For example, in powershell, just type gwmi Win32_BootConfiguration to get your answer.

Use LoadPatientRecords() after a successful insertion.

Try the below code

private void btnSubmit_Click(object sender, EventArgs e)
{
        if (btnSubmit.Text == "Clear")
        {
            btnSubmit.Text = "Submit";

            txtpFirstName.Focus();
        }
        else
        {
           btnSubmit.Text = "Clear";
           int result = AddPatientRecord();
           if (result > 0)
           {
               MessageBox.Show("Insert Successful");

               LoadPatientRecords();
           }
           else
               MessageBox.Show("Insert Fail");
         }
}

You can reorder the operands:

$null -eq $foo

Note that -eq in PowerShell is not an equivalence relation.

What you need is strstr()(or stristr(), like LucaB pointed out). Use it like this:

if(strstr($text, "world")) {/* do stuff */}

Please try the following code:

while IFS= read -r line; do
    echo "$line"
done < file

I have come out with an easy method to assign JavaScript variables using PHP.

It uses HTML5 data attributes to store PHP variables and then it's assigned to JavaScript on page load.

A complete tutorial can be found here.

Example:

<?php
    $variable_1 = "QNimate";
    $variable_2 = "QScutter";
?>
    <span id="storage" data-variable-one="<?php echo $variable_1; ?>" data-variable-two="<?php echo $variable_2; ?>"></span>
<?php

Here is the JavaScript code

var variable_1 = undefined;
var variable_2 = undefined;

window.onload = function(){
    variable_1 = document.getElementById("storage").getAttribute("data-variable-one");
    variable_2 = document.getElementById("storage").getAttribute("data-variable-two");
}

Modern browsers

Plain JavaScript

If a DOM element which is removed is reference-free (no references pointing to it) then yes - the element itself is picked up by the garbage collector as well as any event handlers/listeners associated with it.

var a = document.createElement('div');
var b = document.createElement('p');
// Add event listeners to b etc...
a.appendChild(b);
a.removeChild(b);
b = null; 
// A reference to 'b' no longer exists 
// Therefore the element and any event listeners attached to it are removed.

However; if there are references that still point to said element, the element and its event listeners are retained in memory.

var a = document.createElement('div');
var b = document.createElement('p'); 
// Add event listeners to b etc...
a.appendChild(b);
a.removeChild(b); 
// A reference to 'b' still exists 
// Therefore the element and any associated event listeners are still retained.

jQuery

It would be fair to assume that the relevant methods in jQuery (such as remove()) would function in the exact same way (considering remove() was written using removeChild() for example).

However, this isn't true; the jQuery library actually has an internal method (which is undocumented and in theory could be changed at any time) called cleanData() (here is what this method looks like) which automatically cleans up all the data/events associated with an element upon removal from the DOM (be this via. remove(), empty(), html("") etc).

Older browsers

Older browsers - specifically older versions of IE - are known to have memory leak issues due to event listeners keeping hold of references to the elements they were attached to.

If you want a more in-depth explanation of the causes, patterns and solutions used to fix legacy IE version memory leaks, I fully recommend you read this MSDN article on Understanding and Solving Internet Explorer Leak Patterns.

A few more articles relevant to this:

• JScript memory leaks
• Memory leaks in IE8
• JavaScript Memory Leaks

Manually removing the listeners yourself would probably be a good habit to get into in this case (only if the memory is that vital to your application and you are actually targeting such browsers).

Check the XML. It is not a valid xml.

Prolog is the first line with xml version info. It ok not to include it in your xml.

This error is thrown when the parser reads an invalid tag at the start of the document. Normally where the prolog resides.

The password_hash() function in PHP is an inbuilt function , used to create a new password hash with different algorithms and options. the function uses a strong hashing algorithm.

the function take 2 mandetory parametres ($password and $algorithm,) and 1 optional parameter ($options).

$strongPassword = password_hash( $password, $algorithm, $options )

Algoristrong textthms allowed right now for password_hash() are :

• PASSWORD_DEFAULT

• PASSWORD_BCRYPT

• ASSWORD_ARGON2I

• PASSWORD_ARGON2ID

example : echo password_hash("abcDEF", PASSWORD_DEFAULT);

answer : $2y$10$KwKceUaG84WInAif5ehdZOkE4kHPWTLp0ZK5a5OU2EbtdwQ9YIcGy

answer :$2y$10$SNly5bFzB/R6OVbBMq1bj.yiOZdsk6Mwgqi4BLR2sqdCvMyv/AyL2

to use the BCRYPT as password, use option cost =12 in an array , also change 1st parameter $password to some strong password like "wgt167yuWBGY@#1987__"

Example: echo password_hash("wgt167yuWBGY@#1987__", PASSWORD_BCRYPT ,['cost' => 12]);

I am going to throw you a curve ball here. If I have said it once I have said it a hundred times. Marshaling operations like Invoke or BeginInvoke are not always the best methods for updating the UI with worker thread progress.

In this case it usually works better to have the worker thread publish its progress information to a shared data structure that the UI thread then polls at regular intervals. This has several advantages.

• It breaks the tight coupling between the UI and worker thread that Invoke imposes.
• The UI thread gets to dictate when the UI controls get updated...the way it should be anyway when you really think about it.
• There is no risk of overrunning the UI message queue as would be the case if BeginInvoke were used from the worker thread.
• The worker thread does not have to wait for a response from the UI thread as would be the case with Invoke.
• You get more throughput on both the UI and worker threads.
• Invoke and BeginInvoke are expensive operations.

So in your calcClass create a data structure that will hold the progress information.

public class calcClass
{
  private double percentComplete = 0;

  public double PercentComplete
  {
    get 
    { 
      // Do a thread-safe read here.
      return Interlocked.CompareExchange(ref percentComplete, 0, 0);
    }
  }

  public testMethod(object input)
  {
    int count = 1000;
    for (int i = 0; i < count; i++)
    {
      Thread.Sleep(10);
      double newvalue = ((double)i + 1) / (double)count;
      Interlocked.Exchange(ref percentComplete, newvalue);
    }
  }
}

Then in your MainWindow class use a DispatcherTimer to periodically poll the progress information. Configure the DispatcherTimer to raise the Tick event on whatever interval is most appropriate for your situation.

public partial class MainWindow : Window
{
  public void YourDispatcherTimer_Tick(object sender, EventArgs args)
  {
    YourProgressBar.Value = calculation.PercentComplete;
  }
}

The related_name attribute specifies the name of the reverse relation from the User model back to your model.

If you don't specify a related_name, Django automatically creates one using the name of your model with the suffix _set, for instance User.map_set.all().

If you do specify, e.g. related_name=maps on the User model, User.map_set will still work, but the User.maps. syntax is obviously a bit cleaner and less clunky; so for example, if you had a user object current_user, you could use current_user.maps.all() to get all instances of your Map model that have a relation to current_user.

The Django documentation has more details.

It's not really a function of git, msys, or bash; every windows console program is stuck using the same cumbersome copy/paste mechanism for historical reasons. Turning on QuickEdit mode can help -- or you can install a nice alternative console like this one, and change your git bash shortcut to use it instead.

You almost always want autocrlf=input unless you really know what you are doing.

Some additional context below:

It should be either core.autocrlf=true if you like DOS ending or core.autocrlf=input if you prefer unix-newlines. In both cases, your Git repository will have only LF, which is the Right Thing. The only argument for core.autocrlf=false was that automatic heuristic may incorrectly detect some binary as text and then your tile will be corrupted. So, core.safecrlf option was introduced to warn a user if a irreversable change happens. In fact, there are two possibilities of irreversable changes -- mixed line-ending in text file, in this normalization is desirable, so this warning can be ignored, or (very unlikely) that Git incorrectly detected your binary file as text. Then you need to use attributes to tell Git that this file is binary.

The above paragraph was originally pulled from a thread on gmane.org, but it has since gone down.

Don't forget that an input field must be visible first, thereafter you're able to focus it.

$("#elementid").show();
$("#elementid input[type=text]").focus();

I would use:

if (Stream.of("a","b","c").anyMatch("a"::equals)) {
    //Code to execute
};

or:

Stream.of("a","b","c")
    .filter("a"::equals)
    .findAny()
    .ifPresent(ignore -> /*Code to execute*/);

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

Here is the way I do it:

@Entity
public class ServerInstanceSeq
{
    @Id //mysql bigint(20)
    @SequenceGenerator(name="ServerInstanceIdSeqName", sequenceName="ServerInstanceIdSeq", allocationSize=20)
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="ServerInstanceIdSeqName")
    public Long id;

}

ServerInstanceSeq sis = new ServerInstanceSeq();
session.beginTransaction();
session.save(sis);
session.getTransaction().commit();
System.out.println("sis.id after save: "+sis.id);

Oh, I found it. You use last instead of break

for my $entry (@array){
    if ($string eq "text"){
         last;
    }
}

Another option: when cell type is unknown at compile time and cell is formatted as Date Range.Value returns a desired DateTime object.

public static DateTime? GetAsDateTimeOrDefault(Range cell)
{
    object cellValue = cell.Value;
    if (cellValue is DateTime result)
    {
        return result;
    }
    return null;
}

At the time of writing this answer, there was no method to embed which let the user navigate inside folders and view the files without her leaving the website (the method in other answers, makes everything open in a new tab on google drive website), so I made my own tool for it. To embed a drive, paste the iframe code below in your HTML:

<iframe src="https://googledriveembedder.collegefam.com/?key=YOUR_API_KEY&folderid=FOLDER_ID_WHIHCH_IS_PUBLICLY_VIEWABLE" style="border:none;" width="100%"></iframe>

In the above code, you need to have your own API key and the folder ID. You can set the height as per your wish.

To get the API key:

1.) Go to https://console.developers.google.com/ Create a new project.

2.) From the menu button, go to 'APIs and Services' --> 'Dashboard' --> Click on 'Enable APIs and Services'.

3.) Search for 'Google Drive API', enable it. Then go to "credentials' tab, and create credentials. Keep your API key unrestricted.

4.) Copy the newly generated API key.

To get the folder ID:

1.)Go to the google drive folder you want to embed (for example, drive.google.com/drive/u/0/folders/1v7cGug_e3lNT0YjhvtYrwKV7dGY-Nyh5u [this is not a real folder]) Ensure that the folder is publicly shared and visible to anyone.

2.) Copy the part after 'folders/', this is your folder ID.

Now put both the API key and folder id in the above code and embed.

I made the widget keeping mobile users in mind, however it suits both mobile and desktop. If you run into issues, leave a comment here. I have attached some screenshots of the content of the iframe here.

This happens when a keyword argument is specified that overwrites a positional argument. For example, let's imagine a function that draws a colored box. The function selects the color to be used and delegates the drawing of the box to another function, relaying all extra arguments.

def color_box(color, *args, **kwargs):
    painter.select_color(color)
    painter.draw_box(*args, **kwargs)

Then the call

color_box("blellow", color="green", height=20, width=30)

will fail because two values are assigned to color: "blellow" as positional and "green" as keyword. (painter.draw_box is supposed to accept the height and width arguments).

This is easy to see in the example, but of course if one mixes up the arguments at call, it may not be easy to debug:

# misplaced height and width
color_box(20, 30, color="green")

Here, color is assigned 20, then args=[30] and color is again assigned "green".

You can calculate the total (and from that the desired percentage) by using a subquery in the FROM clause:

SELECT Name,
       SUM(Value) AS "SUM(VALUE)",
       SUM(Value) / totals.total AS "% of Total"
FROM   table1,
       (
           SELECT Name,
                  SUM(Value) AS total
           FROM   table1
           GROUP BY Name
       ) AS totals
WHERE  table1.Name = totals.Name
AND    Year BETWEEN 2000 AND 2001
GROUP BY Name;

Note that the subquery does not have the WHERE clause filtering the years.

Use a data list instead.

XCode 8.2, iOS 10, Swift 3: now there's an unselectedItemTintColor attribute for tabBar:

self.tabBar.unselectedItemTintColor = UIColor(red: 0/255.0, green: 200/255.0, blue: 0/255.0, alpha: 1.0)

I doubt the standard library supports this.

But you can use the google maps utility library:

http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries#MarkerWithLabel

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);

var myOptions = {
    zoom: 8,
    center: myLatlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };

map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);

var marker = new MarkerWithLabel({
   position: myLatlng,
   map: map,
   draggable: true,
   raiseOnDrag: true,
   labelContent: "A",
   labelAnchor: new google.maps.Point(3, 30),
   labelClass: "labels", // the CSS class for the label
   labelInBackground: false
 });

The basics about marker can be found here: https://developers.google.com/maps/documentation/javascript/overlays#Markers

Another solution could be, that you deleted a file from your Project by just removing it in your file system, instead of removing it within your project.

The initialization method easiest to remember is

vec = vector(,10); #the same as "vec = vector(length = 10);"

The values of vec are: "[1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE" (logical mode) by default.

But after setting a character value, like

vec[2] = 'abc'

vec becomes: "FALSE" "abc" "FALSE" "FALSE" "FALSE" "FALSE" "FALSE" "FALSE" "FALSE" "FALSE"", which is of the character mode.

When you have Overridden Methods with same Name Use the helper below

public static TValue GetControllerMethodAttributeValue<T, TT, TAttribute, TValue>(this T type, Expression<Func<T, TT>> exp, Func<TAttribute, TValue> valueSelector) where TAttribute : Attribute
        {
            var memberExpression = exp?.Body as MethodCallExpression;

            if (memberExpression.Method.GetCustomAttributes(typeof(TAttribute), false).FirstOrDefault() is TAttribute attr && valueSelector != null)
            {
                return valueSelector(attr);
            }

            return default(TValue);
        }

Usage: var someController = new SomeController(Some params); var str = typeof(SomeController).GetControllerMethodAttributeValue(x => someController.SomeMethod(It.IsAny()), (RouteAttribute routeAttribute) => routeAttribute.Template);

With Java 5 variable args, so you don't have to stuff all your strings into a collection or array explicitly:

import junit.framework.Assert;
import org.junit.Test;

public class StringUtil
{
    public static String join(String delim, String... strings)
    {
        StringBuilder builder = new StringBuilder();

        if (strings != null)
        {
            for (String str : strings)
            {
                if (builder.length() > 0)
                {
                    builder.append(delim).append(" ");
                }
                builder.append(str);
            }
        }           
        return builder.toString();
    }
    @Test
    public void joinTest()
    {
        Assert.assertEquals("", StringUtil.join(",", null));
        Assert.assertEquals("", StringUtil.join(",", ""));
        Assert.assertEquals("", StringUtil.join(",", new String[0]));
        Assert.assertEquals("test", StringUtil.join(",", "test"));
        Assert.assertEquals("foo, bar", StringUtil.join(",", "foo", "bar"));
        Assert.assertEquals("foo, bar, x", StringUtil.join(",", "foo", "bar", "x"));
    }
}

Run your program with valgrind of linked to efence. That will tell you where the pointer is being dereferenced and most likely fix your problem if you fix all the errors they tell you about.

String[] split = data.split("\\|",-1);

This is not the actual requirement in all the time. The Drawback of above is show below:

Scenerio 1:
When all data are present:
    String data = "5|6|7||8|9|10|";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 7
    System.out.println(splt.length); //output: 8

When data is missing:

Scenerio 2: Data Missing
    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output: 8

Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.

    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output:7

What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.

var string = 123 (is string),

console.log(int);  //Output will be 123.

I would recommend to call the script like this

...
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="/js/my.js"></script>
</body>

The js and css files must be treat differently

Put jquery as the first before other JS scripts at the bottom of <BODY> tag

• The problem caused is that they block parallel downloads. The HTTP/1.1 specification suggests that browsers download no more than two components in parallel per hostname.
• So select 2 (two) most important scripts on your page like analytic and pixel script on the <head> tags and let the rest including the jquery to be called on the bottom <body> tag.

Put CSS style on top of <HEAD> tag after the other more priority tags

• Moving style sheets to the document HEAD makes pages appear to be loading faster. This is because putting style sheets in the HEAD allows the page to render progressively.
• So for css sheets, it is better to put them all on the <head> tag but let the style that shall be immediately rendered to be put in <style> tags inside <HEAD> and the rest in <body>.

You may also find other suggestion when you test your page like on Google PageSpeed Insight

I have been using the following solution since over a year, it works with IE 7 and 8 as well.

<style>
.outer {
    font-size: 0;
    width: 400px;
    height: 400px;
    background: orange;
    text-align: center;
    display: inline-block;
}

.outer .emptyDiv {
    height: 100%;
    background: orange;
    visibility: collapse;
}

.outer .inner {
    padding: 10px;
    background: red;
    font: bold 12px Arial;
}

.verticalCenter {
    display: inline-block;
    *display: inline;
    zoom: 1;
    vertical-align: middle;
}
</style>

<div class="outer">
    <div class="emptyDiv verticalCenter"></div>
    <div class="inner verticalCenter">
        <p>Line 1</p>
        <p>Line 2</p>
    </div>
</div>

This is the good way using formats:

const now = moment()
now.format("hh:mm:ss K") // 1:00:00 PM
now.format("HH:mm:ss") // 13:00:00

Red more about moment sring format

No, there is no built-in MySQL command for that. There are various tools and scripts that support it, you can kill some connections manually or restart the server (but that will be slower).

Use SHOW PROCESSLIST to view all connections, and KILL the process ID's you want to kill.

You could edit the timeout setting to have the MySQL daemon kill the inactive processes itself, or raise the connection count. You can even limit the amount of connections per username, so that if the process keeps misbehaving, the only affected process is the process itself and no other clients on your database get locked out.

If you can't connect yourself anymore to the server, you should know that MySQL always reserves 1 extra connection for a user with the SUPER privilege. Unless your offending process is for some reason using a username with that privilege...

Then after you can access your database again, you should fix the process (website) that's spawning that many connections.

For me the first answer appears a bit confusing, so to make it short and clean:

npm install <package_name> saves any specified packages into dependencies by default. Additionally, you can control where and how they get saved with some additional flags:

npm install <package_name> --no-save Prevents saving to dependencies.

npm install <package_name> ---save-dev updates the devDependencies in your package. These are only used for local testing and development.

You can read more at in the dcu

None of this was really right for me. I wanted something that would purge all local branches that were tracking a remote branch, on origin, where the remote branch has been deleted (gone). I did not want to delete local branches that were never set up to track a remote branch (i.e.: my local dev branches). Also I wanted a simple one-liner that just uses git, or other simple CLI tools, rather than writing custom scripts. I ended up using a bit of grep and awk to make this simple command.

This is ultimately what ended up in my ~/.gitconfig:

[alias]
  prune-branches = !git remote prune origin && git branch -vv | grep ': gone]' | awk '{print $1}' | xargs -r git branch -D

Here is a git config --global ... command for easily adding this as git prune-branches:

git config --global alias.prune-branches '!git remote prune origin && git branch -vv | grep '"'"': gone]'"'"' | awk '"'"'{print $1}'"'"' | xargs -r git branch -d'

NOTE: In the config command, I use the -d option to git branch rather than -D, as I do in my actual config. I use -D because I don't want to hear Git complain about unmerged branches. You may want this functionality as well. If so, simply use -D instead of -d at the end of that config command.

(Jun-Dec 2016) Most answers here are now out-of-date as: 1) GData APIs are the previous generation of Google APIs, and that's why it was hard for @Josh Brown to find that old GData Docs API documentation. While not all GData APIs have been deprecated, all newer Google APIs do not use the Google Data protocol; and 2) Google released a new Google Sheets API (not GData). In order to use the new API, you need to get the Google APIs Client Library for Python (it's as easy as pip install -U google-api-python-client [or pip3 for Python 3]) and use the latest Sheets API v4+, which is much more powerful & flexible than older API releases.

Here's one code sample from the official docs to help get you kickstarted. However, here are slightly longer, more "real-world" examples of using the API you can learn from (videos plus blog posts):

• Migrating SQL data to a Sheet plus code deep dive post
• Formatting text using the Sheets API plus code deep dive post
• Generating slides from spreadsheet data plus code deep dive post
• Those and others in the Sheets API video library

The latest Sheets API provides features not available in older releases, namely giving developers programmatic access to a Sheet as if you were using the user interface (create frozen rows, perform cell formatting, resizing rows/columns, adding pivot tables, creating charts, etc.), but NOT as if it was some database that you could perform searches on and get selected rows from. You'd basically have to build a querying layer on top of the API that does this. One alternative is to use the Google Charts Visualization API query language, which does support SQL-like querying. You can also query from within the Sheet itself. Be aware that this functionality existed before the v4 API, and that the security model was updated in Aug 2016. To learn more, check my G+ reshare to a full write-up from a Google Developer Expert.

Also note that the Sheets API is primarily for programmatically accessing spreadsheet operations & functionality as described above, but to perform file-level access such as imports/exports, copy, move, rename, etc., use the Google Drive API instead. Examples of using the Drive API:

• Listing your files in Google Drive and code deep dive post
• Google Drive: Uploading & Downloading Files plus "Poor man's plain text to PDF converter" code deep dive post (*)
• Exporting a Google Sheet as CSV blog post only

(*) - TL;DR: upload plain text file to Drive, import/convert to Google Docs format, then export that Doc as PDF. Post above uses Drive API v2; this follow-up post describes migrating it to Drive API v3, and here's a developer video combining both "poor man's converter" posts.

To learn more about how to use Google APIs with Python in general, check out my blog as well as a variety of Google developer videos (series 1 and series 2) I'm producing.

ps. As far as Google Docs goes, there isn't a REST API available at this time, so the only way to programmatically access a Doc is by using Google Apps Script (which like Node.js is JavaScript outside of the browser, but instead of running on a Node server, these apps run in Google's cloud; also check out my intro video.) With Apps Script, you can build a Docs app or an add-on for Docs (and other things like Sheets & Forms).

UPDATE Jul 2018: The above "ps." is no longer true. The G Suite developer team pre-announced a new Google Docs REST API at Google Cloud NEXT '18. Developers interested in getting into the early access program for the new API should register at https://developers.google.com/docs.

UPDATE Feb 2019: The Docs API launched to preview last July is now available generally to all... read the launch post for more details.

UPDATE Nov 2019: In an effort to bring G Suite and GCP APIs more inline with each other, earlier this year, all G Suite code samples were partially integrated with GCP's newer (lower-level not product) Python client libraries. The way auth is done is similar but (currently) requires a tiny bit more code to manage token storage, meaning rather than our libraries manage storage.json, you'll store them using pickle (token.pickle or whatever name you prefer) instead, or choose your own form of persistent storage. For you readers here, take a look at the updated Python quickstart example.

I guess this will help you.

JSONObject jsonObj = new JSONObject(jsonStr);

JSONArray ja_data = jsonObj.getJSONArray("data");
int length = jsonObj.length();
for(int i=0; i<length; i++) {
  JSONObject jsonObj = ja_data.getJSONObject(i);
  Toast.makeText(this, jsonObj.getString("Name"), Toast.LENGTH_LONG).show();

  // getting inner array Ingredients
  JSONArray ja = jsonObj.getJSONArray("Ingredients");
  int len = ja.length();

  ArrayList<String> Ingredients_names = new ArrayList<>();
  for(int j=0; j<len; j++) {
    JSONObject json = ja.getJSONObject(j);
    Ingredients_names.add(json.getString("name"));
  }
}

As a C++ Developer here's some simply guidelines:

1. Use pointers only when absolutely necessary
2. If you need a pointer, doublecheck if a SmartPointer is a possibility
3. Use the GRASP Creator pattern.

As for the detection of memory leaks personally I've always used Visual Leak Detector and find it to be very useful.

You can stop the 2-line separation in the output by using

    with open('t.ini') as f:
       for line in f:
           print line.strip()
           if 'str' in line:
              break

These are the droids you're looking for. This is taken from validator.js which is the library you should really use to do this. But if you want to roll your own, who am I to stop you? If you want pure regex then you can just take out the length check. I think it's a good idea to test the length of the URL though if you really want to determine compliance with the spec.

 function isURL(str) {
     var urlRegex = '^(?!mailto:)(?:(?:http|https|ftp)://)(?:\\S+(?::\\S*)?@)?(?:(?:(?:[1-9]\\d?|1\\d\\d|2[01]\\d|22[0-3])(?:\\.(?:1?\\d{1,2}|2[0-4]\\d|25[0-5])){2}(?:\\.(?:[0-9]\\d?|1\\d\\d|2[0-4]\\d|25[0-4]))|(?:(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)(?:\\.(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)*(?:\\.(?:[a-z\\u00a1-\\uffff]{2,})))|localhost)(?::\\d{2,5})?(?:(/|\\?|#)[^\\s]*)?$';
     var url = new RegExp(urlRegex, 'i');
     return str.length < 2083 && url.test(str);
}

Very easy step by step (100% working and tested)

step1: Create method on first view controller

 func updateProcessStatus(isCompleted : Bool){
    if isCompleted{
        self.labelStatus.text = "Process is completed"
    }else{
        self.labelStatus.text = "Process is in progress"
    }
}

step2: Set delegate while push to second view controller

@IBAction func buttonAction(_ sender: Any) {

    let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController") as! secondViewController
    secondViewController.delegate = self
    self.navigationController?.pushViewController(secondViewController, animated: true)
}

step3: set delegate like

class ViewController: UIViewController,ProcessStatusDelegate {

step4: Create protocol

protocol ProcessStatusDelegate:NSObjectProtocol{
func updateProcessStatus(isCompleted : Bool)
}

step5: take a variable

var delegate:ProcessStatusDelegate?

step6: While go back to previous view controller call delegate method so first view controller notify with data

@IBAction func buttonActionBack(_ sender: Any) {
    delegate?.updateProcessStatus(isCompleted: true)
    self.navigationController?.popViewController(animated: true)
}

@IBAction func buttonProgress(_ sender: Any) {
    delegate?.updateProcessStatus(isCompleted: false)
    self.navigationController?.popViewController(animated: true)

}

You can use CAST function:

Your script seems incorrect in several places.

Try this

var timetemp = document.getElementsByTagName('input');

for (var i = 0; i < timetemp.length; i++){
    if (timetemp[i].value == ""){
        alert ('No value');
    }
    else{
        alert (timetemp[i].value);
    }
}

Example: http://jsfiddle.net/jasongennaro/FSzT2/

Here's what I changed:

1. started by getting all the inputs via TagName. This makes an array
2. initialized i with a var and then looped through the timetemp array using the timetemp.length property.
3. used timetemp[i] to reference each input in the for statement

If you just want the bug fix to be integrated into the branch, git cherry-pick the relevant commit(s).

Predicate<Client> hasSameNameAsOneUser = 
    c -> users.stream().anyMatch(u -> u.getName().equals(c.getName()));

return clients.stream()
              .filter(hasSameNameAsOneUser)
              .collect(Collectors.toList());

But this is quite inefficient, because it's O(m * n). You'd better create a Set of acceptable names:

Set<String> acceptableNames = 
    users.stream()
         .map(User::getName)
         .collect(Collectors.toSet());

return clients.stream()
              .filter(c -> acceptableNames.contains(c.getName()))
              .collect(Collectors.toList());

Also note that it's not strictly equivalent to the code you have (if it compiled), which adds the same client twice to the list if several users have the same name as the client.

I had this issue when I was using VS 2010. My solution configuration has (Debug) selected. I resolved this by unchecking the Optimize Code property under project properties. Project (right Click)=> Properties => Build (tab) => uncheck Optimize code

you can use jQuery to achieve this easily.

CSS

.left, .right {border:1px solid #cccccc;}

jQuery

$(document).ready(function() {
    var leftHeight = $('.left').height();
    $('.right').css({'height':leftHeight});
});

HTML

   <div class="left">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi malesuada, lacus eu dapibus tempus, ante odio aliquet risus, ac ornare orci velit in sapien. Duis suscipit sapien vel nunc scelerisque in pretium velit mattis. Cras vitae odio sed eros mollis malesuada et eu nunc.</p>
   </div>
   <div class="right">
    <p>Lorem ipsum dolor sit amet.</p>
   </div>

You'll need to include jQuery

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

Try the Offstage widget

if attribute offstage:true the not occupy the physical space and invisible,

if attribute offstage:false it will occupy the physical space and visible

Offstage(
   offstage: true,
   child: Text("Visible"),
),

You forgot to put z as an bind variable.

The following EXECUTE command runs a PL/SQL statement that references a stored procedure:

SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')

Note that the value returned by the stored procedure is being return into :Z

I was able to resolve the problem by manually creating the following registry key:

HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs

above solution doesn't work for me for unknown reason. below is my workaround which was worked successfully.

1) DO NOT generate a new ssh key by using command ssh-keygen -t rsa -C"[email protected]", you can delete existing SSH keys.

2) but use Git GUI, -> "Help" -> "Show ssh key" -> "Generate key", the key will saved to ssh automatically and no need to use ssh-add anymore.

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

You can use JQuery .load() method:

http://api.jquery.com/load/

 $( "#content" ).load( "ajax/test.html div#content" );

[self.navigationController.view addSubview:overlayView]; is what you really want

Am I missing something?

Yes. ;-)

This phenomenon exists because of the uniform interface constraint. REST likes using already existing standards instead of reinventing the wheel. The HTTP standard has already proven to be highly scalable (the web is working for a while). Why should we fix something which is not broken?!

note: The uniform interface constraint is important if you want to decouple the clients from the service. It is similar to defining interfaces for classes in order to decouple them from each other. Ofc. in here the uniform interface consists of standards like HTTP, MIME types, URI, RDF, linked data vocabs, hydra vocab, etc...

I came across this post w/a similar issue. My fix was to add a hidden field to hold my invalid state for me.

<input type="hidden" ng-model="vm.application.isValid" required="" />

In my case I had a nullable bool which a person had to select one of two different buttons. if they answer yes, an entity is added to the collection and the state of the button changes. Until all of the questions get answered, (one of the buttons in each of the pairs has a click) the form is not valid.

vm.hasHighSchool = function (attended) { 
  vm.application.hasHighSchool = attended;
  applicationSvc.addSchool(attended, 1, vm.application);
}

<input type="hidden" ng-model="vm.application.hasHighSchool" required="" />
<div class="row">
  <div class="col-lg-3"><label>Did You Attend High School?</label><label class="required" ng-hide="vm.application.hasHighSchool != undefined">*</label></div>
  <div class="col-lg-2">
    <button value="Yes" title="Yes" ng-click="vm.hasHighSchool(true)" class="btn btn-default" ng-class="{'btn-success': vm.application.hasHighSchool == true}">Yes</button>
    <button value="No" title="No" ng-click="vm.hasHighSchool(false)" class="btn btn-default" ng-class="{'btn-success':  vm.application.hasHighSchool == false}">No</button>
  </div>
</div>

No, it's not possible using just one selector. The :first-of-type pseudo-class selects the first element of its type (div, p, etc). Using a class selector (or a type selector) with that pseudo-class means to select an element if it has the given class (or is of the given type) and is the first of its type among its siblings.

Unfortunately, CSS doesn't provide a :first-of-class selector that only chooses the first occurrence of a class. As a workaround, you can use something like this:

.myclass1 { color: red; }
.myclass1 ~ .myclass1 { color: /* default, or inherited from parent div */; }

Explanations and illustrations for the workaround are given here and here.

Here is a solution in Java a bit lengthy but works..

public static int getHeight (Node root){
    int lheight = 0, rheight = 0;
    if(root==null) {
        return 0;
    }
    else {
        if(root.left != null) {
            lheight = 1 + getHeight(root.left);
            System.out.println("lheight" + " " + lheight);
        }
        if (root.right != null) {
            rheight = 1+ getHeight(root.right);
            System.out.println("rheight" + " " + rheight);
        }
        if(root != null && root.left == null && root.right == null) {
            lheight += 1; 
            rheight += 1;
        }

    }
    return Math.max(lheight, rheight);
    }

For Swift 3, you can use index(where:) and include a closure that does the comparison of an object in the array ($0) with whatever you are looking for.

var array = ["alpha", "beta", "gamma"]
if let index = array.index(where: {$0 == "beta"}) {
  array.remove(at: index)
}

This can be done with array_splice however, array_splice fails when inserting an array or using a string key. I wrote a function to handle all cases:

function array_insert(&$arr, $index, $val)
{
    if (is_string($index))
        $index = array_search($index, array_keys($arr));
    if (is_array($val))
        array_splice($arr, $index, 0, [$index => $val]);
    else
        array_splice($arr, $index, 0, $val);
}

OAuth 2.0 defines a protocol, i.e. specifies how tokens are transferred, JWT defines a token format.

OAuth 2.0 and "JWT authentication" have similar appearance when it comes to the (2nd) stage where the Client presents the token to the Resource Server: the token is passed in a header.

But "JWT authentication" is not a standard and does not specify how the Client obtains the token in the first place (the 1st stage). That is where the perceived complexity of OAuth comes from: it also defines various ways in which the Client can obtain an access token from something that is called an Authorization Server.

So the real difference is that JWT is just a token format, OAuth 2.0 is a protocol (that may use a JWT as a token format).

This took me a while to figure out. Simply put, the table that references the other table already has data in it and one or more of its values does not exist in the parent table.

e.g. Table2 has the following data:

UserID    PostID    Title    Summary
5         1         Lorem    Ipsum dolor sit

Table1

UserID    Password    Username    Email
9         ********    JohnDoe     [email protected]

If you try to ALTER table2 and add a foreign key then the query will fail because UserID=5 doesn't exist in Table1.

As Blazemonger said, #parent, .panel and .collapse have to be direct descendants. However, if You can't change Your html, You can do workaround using bootstrap events and methods with the following code:

$('#your-parent .collapse').on('show.bs.collapse', function (e) {
    var actives = $('#your-parent').find('.in, .collapsing');
    actives.each( function (index, element) {
        $(element).collapse('hide');
    })
})

TL&DR: When you typically get data from a server, it is sent in bytes. The rationale is that these bytes will need to be 'decoded' by the recipient, who should know how to use the data. You should decode the binary upon arrival to not get 'b' (bytes) but instead a string.

Use case:

import requests    
def get_data_from_url(url):
        response = requests.get(url_to_visit)
        response_data_split_by_line = response.content.decode('utf-8').splitlines()
        return response_data_split_by_line

In this example, I decode the content that I received into UTF-8. For my purposes, I then split it by line, so I can loop through each line with a for loop.

Finding difference by index. Assuming df1 is a subset of df2 and the indexes are carried forward when subsetting

df1.loc[set(df1.index).symmetric_difference(set(df2.index))].dropna()

# Example

df1 = pd.DataFrame({"gender":np.random.choice(['m','f'],size=5), "subject":np.random.choice(["bio","phy","chem"],size=5)}, index = [1,2,3,4,5])

df2 =  df1.loc[[1,3,5]]

df1

 gender subject
1      f     bio
2      m    chem
3      f     phy
4      m     bio
5      f     bio

df2

  gender subject
1      f     bio
3      f     phy
5      f     bio

df3 = df1.loc[set(df1.index).symmetric_difference(set(df2.index))].dropna()

df3

  gender subject
2      m    chem
4      m     bio

Hi to use the thread pool in Python you can use this library :

from multiprocessing.dummy import Pool as ThreadPool

and then for use, this library do like that :

pool = ThreadPool(threads)
results = pool.map(service, tasks)
pool.close()
pool.join()
return results

The threads are the number of threads that you want and tasks are a list of task that most map to the service.

OFFSET is nothing but a keyword to indicate starting cursor in table

SELECT column FROM table LIMIT 18 OFFSET 8 -- fetch 18 records, begin with record 9 (OFFSET 8)

you would get the same result form

SELECT column FROM table LIMIT 8, 18

visual representation (R is one record in the table in some order)

 OFFSET        LIMIT          rest of the table
 __||__   _______||_______   __||__
/      \ /                \ /
RRRRRRRR RRRRRRRRRRRRRRRRRR RRRR...
         \________________/
                 ||
             your result

Currently the only way I've found is with Deploy Tokens

I have three tests for an Internet connection.

• Reference System.Net and System.Net.Sockets
• Add the following test functions:

Test 1

public bool IsOnlineTest1()
{
    try
    {
        IPHostEntry dummy = Dns.GetHostEntry("https://www.google.com");
        return true;
    }
    catch (SocketException ex)
    {
        return false;
    }
}

Test 2

public bool IsOnlineTest2()
{
    try
    {
        IPHostEntry dummy = Dns.GetHostEntry("https://www.google.com");
        return true;
    }
    catch (SocketException ex)
    {
        return false;
    }
}

Test 3

public bool IsOnlineTest3()
{
    System.Net.WebRequest req = System.Net.WebRequest.Create("https://www.google.com");
    System.Net.WebResponse resp = default(System.Net.WebResponse);
    try
    {
        resp = req.GetResponse();
        resp.Close();
        req = null;
        return true;
    }
    catch (Exception ex)
    {
        req = null;
        return false;
    }
}

Performing the tests

If you make a Dictionary of String and Boolean called CheckList, you can add the results of each test to CheckList.

Now, recurse through each KeyValuePair using a for...each loop.

If CheckList contains a Value of true, then you know there is an Internet connection.

You have to manually copy each key/value pair to a new map. This is a loop that people have to reprogram any time they want a deep copy of a map.

You can automatically generate the function for this by installing mapper from the maps package using

go get -u github.com/drgrib/maps/cmd/mapper

and running

mapper -types string:aStruct

which will generate the file map_float_astruct.go containing not only a (deep) Copy for your map but also other "missing" map functions ContainsKey, ContainsValue, GetKeys, and GetValues:

func ContainsKeyStringAStruct(m map[string]aStruct, k string) bool {
    _, ok := m[k]
    return ok
}

func ContainsValueStringAStruct(m map[string]aStruct, v aStruct) bool {
    for _, mValue := range m {
        if mValue == v {
            return true
        }
    }

    return false
}

func GetKeysStringAStruct(m map[string]aStruct) []string {
    keys := []string{}

    for k, _ := range m {
        keys = append(keys, k)
    }

    return keys
}

func GetValuesStringAStruct(m map[string]aStruct) []aStruct {
    values := []aStruct{}

    for _, v := range m {
        values = append(values, v)
    }

    return values
}

func CopyStringAStruct(m map[string]aStruct) map[string]aStruct {
    copyMap := map[string]aStruct{}

    for k, v := range m {
        copyMap[k] = v
    }

    return copyMap
}

Full disclosure: I am the creator of this tool. I created it and its containing package because I found myself constantly rewriting these algorithms for the Go map for different type combinations.

Assuming Bootstrap and Popper libraries were installed using Nuget package manager, for a web application using Visual Studio, in the Master page file (Site.Master), right below where body tag begins, include the reference to popper.min.js by typing:

<script src="Scripts/umd/popper.min.js"></script>

Here is an image to better display the location:

Notice the reference of the popper library to be added should be the one inside umd folder and not the one outside on Scripts folder.

This should fix the problem.

I had the same problem. In order to modify variables from different classes, I made them extend the class they were to modify. I also made the super class's variables static so they can be changed by anything that inherits them. I also made them protected for more flexibility.

Source: Bad experiences. Good lessons.

I believe the intention is for the script in question to fail fast.

To test this yourself, simply type set -e at a bash prompt. Now, try running ls. You'll get a directory listing. Now, type lsd. That command is not recognized and will return an error code, and so your bash prompt will close (due to set -e).

Now, to understand this in the context of a 'script', use this simple script:

#!/bin/bash 
# set -e

lsd 

ls

If you run it as is, you'll get the directory listing from the ls on the last line. If you uncomment the set -e and run again, you won't see the directory listing as bash stops processing once it encounters the error from lsd.

You can use continue

if condition:
    continue
else:
    #do something

If you want to style the subtitle also then simply add this in your custom style.

<item name="android:subtitleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>

People who are looking to get the same result for AppCompat library then this is what I used:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomActivityTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
        <item name="actionBarStyle">@style/MyActionBar</item>
        <!-- other activity and action bar styles here -->
    </style>

    <!-- style for the action bar backgrounds -->
    <style name="MyActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="android:background">@drawable/actionbar_background</item>
        <item name="background">@drawable/actionbar_background</item>
        <item name="android:titleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
        <item name="android:subtitleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
        <item name="titleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
        <item name="subtitleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
     </style>
    <style name="MyTheme.ActionBar.TitleTextStyle" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
        <item name="android:textColor">@color/color_title</item>
      </style>
</resources>

This code can be used to export any file, including csv

// application/octet-stream tells the browser not to try to interpret the file
header('Content-type: application/octet-stream');
header('Content-Length: ' . filesize($data));
header('Content-Disposition: attachment; filename="export.csv"');

Either you can use CSV functions or PHPExcel

or you can try like below

<?php
$file="demo.xls";
$test="<table  ><tr><td>Cell 1</td><td>Cell 2</td></tr></table>";
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file");
echo $test;
?>

The header for .xlsx files is Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

adjust the background-position to move background images in different positions of the div

Comparing two predominant answers

(x%m + m)%m;

and

int r = x%m;
return r<0 ? r+m : r;

Nobody actually mentioned the fact that the first one may throw an OverflowException while the second one won't. Even worse, with default unchecked context, the first answer may return the wrong answer (see mod(int.MaxValue - 1, int.MaxValue) for example). So the second answer not only seems to be faster, but also more correct.

In mdcharm it is like this:

* [Descripción](#descripcion)
* [Funcionamiento](#funcionamiento)
* [Instalación](#instalacion)
* [Configuración](#configuracion)

### Descripción {#descripcion}
### Funcionamiento {#funcionamiento}
### Instalación {#instalacion}
### Configuración {#configuracion}

Named tuples were added in 2.6 for this purpose. Also see os.stat for a similar builtin example.

>>> import collections
>>> Point = collections.namedtuple('Point', ['x', 'y'])
>>> p = Point(1, y=2)
>>> p.x, p.y
1 2
>>> p[0], p[1]
1 2

In recent versions of Python 3 (3.6+, I think), the new typing library got the NamedTuple class to make named tuples easier to create and more powerful. Inheriting from typing.NamedTuple lets you use docstrings, default values, and type annotations.

Example (From the docs):

class Employee(NamedTuple):  # inherit from typing.NamedTuple
    name: str
    id: int = 3  # default value

employee = Employee('Guido')
assert employee.id == 3

There are two main types of margin collapse:

• Collapsing margins between adjacent elements
• Collapsing margins between parent and child elements

Using a padding or border will prevent collapse only in the latter case. Also, any value of overflow different from its default (visible) applied to the parent will prevent collapse. Thus, both overflow: auto and overflow: hidden will have the same effect. Perhaps the only difference when using hidden is the unintended consequence of hiding content if the parent has a fixed height.

Other properties that, once applied to the parent, can help fix this behaviour are:

• float: left / right
• position: absolute
• display: inline-block / flex

You can test all of them here: http://jsfiddle.net/XB9wX/1/.

I should add that, as usual, Internet Explorer is the exception. More specifically, in IE 7 margins do not collapse when some kind of layout is specified for the parent element, such as width.

Sources: Sitepoint's article Collapsing Margins

Prefix is the prefix for url routing. If it's equals to '/' it means it will have no prefix. Then you defined a route with pattern "it should start with /hello".

To create a route for '/' you need to add these lines in your src/Shop/MyShopBundle/Resources/config/routing.yml :

ShopMyShopBundle_homepage:
    pattern:  /
    defaults: { _controller: ShopMyShopBundle:Main:index }

This works in bash, according to this link:

unzip \*.zip

Looks like you are missing a leading slash. Perhaps try:

Scanner s = new Scanner(new File("/home/me/java/ex.txt"));

(as to where it looks for files by default, it is where the JVM is run from for relative paths like the one you have in your question)

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

Please use basename / dirname constructs.

man basename

Several of these things did not work for me... however, this did. Might help someone else in the future. Here is the CSS:

    .img-area {
     display: block;
     padding: 0px 0 0 0px;
     text-indent: 0;
     width: 100%;
     background-size: 100% 95%;
     background-repeat: no-repeat;
     background-image: url("https://yourimage.png");

    }

I would suggest not using pixels for sWidth, instead use percentages. Like below:

   "aoColumnDefs": [
  { "sWidth": "20%", "aTargets": [ 0 ] }, <- start from zero
  { "sWidth": "5%", "aTargets": [ 1 ] },
  { "sWidth": "10%", "aTargets": [ 2 ] },
  { "sWidth": "5%", "aTargets": [ 3 ] },
  { "sWidth": "40%", "aTargets": [ 4 ] },
  { "sWidth": "5%", "aTargets": [ 5 ] },
  { "sWidth": "15%", "aTargets": [ 6 ] }
],
     aoColumns : [
      { "sWidth": "20%"},
      { "sWidth": "5%"},
      { "sWidth": "10%"},
      { "sWidth": "5%"},
      { "sWidth": "40%"},
      { "sWidth": "5%"},
      { "sWidth": "15%"}
    ]
});

Hope it helps.

For Mac users who only have Command Line Tools instead of Xcode, check the /Library/Developer/CommandLineTools directory, for example::

"configurations": [{
    "name": "Mac",
    "includePath": [
            "/usr/local/include",
            // others, e.g.: "/usr/local/opt/ncurses/include",
            "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include",
            "${workspaceFolder}/**"
    ]
}]

You probably need to adjust the path if you have different version of Command Line Tools installed.

Note: You can also open/generate the c_cpp_properties.json file via the C/Cpp: Edit Configurations command from the Command Palette (??P).

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

From:

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

Just use the sys.getsizeof function defined in the sys module.

sys.getsizeof(object[, default]):

Return the size of an object in bytes. The object can be any type of object. All built-in objects will return correct results, but this does not have to hold true for third-party extensions as it is implementation specific.

Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to.

The default argument allows to define a value which will be returned if the object type does not provide means to retrieve the size and would cause a TypeError.

getsizeof calls the object’s __sizeof__ method and adds an additional garbage collector overhead if the object is managed by the garbage collector.

See recursive sizeof recipe for an example of using getsizeof() recursively to find the size of containers and all their contents.

Usage example, in python 3.0:

>>> import sys
>>> x = 2
>>> sys.getsizeof(x)
24
>>> sys.getsizeof(sys.getsizeof)
32
>>> sys.getsizeof('this')
38
>>> sys.getsizeof('this also')
48

If you are in python < 2.6 and don't have sys.getsizeof you can use this extensive module instead. Never used it though.

Try this:

int dayOfWeek = date.get(Calendar.DAY_OF_WEEK);  
String weekday = new DateFormatSymbols().getShortWeekdays()[dayOfWeek];

forEach() :

return value : undefined

originalArray : not modified after the method call

newArray is not created after the end of method call.

map() :

return value : new Array populated with the results of calling a provided function on every element in the calling array

originalArray : not modified after the method call

newArray is created after the end of method call.

Since map builds a new array, using it when you aren't using the
returned array is an anti-pattern; use forEach or for-of instead.

We are looking into adding some kind of formatting to durations in moment.js. See https://github.com/timrwood/moment/issues/463

A couple other libraries that might help out are http://countdownjs.org/ and https://github.com/icambron/twix.js

This is my example.

https://github.com/luisnicg/jQuery-Sortable-and-PHP

You need to catch the order in the update event

    $( "#sortable" ).sortable({
    placeholder: "ui-state-highlight",
    update: function( event, ui ) {
        var sorted = $( "#sortable" ).sortable( "serialize", { key: "sort" } );
        $.post( "form/order.php",{ 'choices[]': sorted});
    }
});

You could also try the following to add an inline style to the element:

$(this).attr('style', 'text-align: center');

This should make sure that other styling rules aren't overriding what you thought would work. I believe inline styles usually get precedence.

EDIT: Also, another tool that may help you is Jash (http://www.billyreisinger.com/jash/). It gives you a javascript command prompt so you can ensure you easily test javascript statements and make sure you're selecting the right element, etc.

Because LINQ can do everything...:

string test = "key1=value1&key2=value2&key3=value3";
var count = test.Where(x => x == '&').Count();

Or if you like, you can use the Count overload that takes a predicate :

var count = test.Count(x => x == '&');

Based on hints from other answers, this is probably the most robust way:

isEmulator = "goldfish".equals(Build.HARDWARE)

Adding one more point to the answer.

.EqualsTo() method gives you provision to compare against culture and case sensitive.

One can also call * a gather parameter (when used in function arguments definition) or a scatter operator (when used at function invocation).

As seen here: Think Python/Tuples/Variable-length argument tuples.

Try wrapping the image with a linearlayout, and set it's background to the border color you want around the text. Then set the padding on the textview to be the thickness you want for your border.

I wrote a shell script for filtering logcat by package name, which I think is more reliable than using

ps | grep com.example.package | cut -c10-15

It uses /proc/$pid/cmdline to find out the actual pid, then do a grep on logcat

https://gist.github.com/kevinxucs/7340e1b1dd2239a2b04a

update VersionedFields
set Value = replace(replace(value,'<iframe','<a>iframe'), '> </iframe>','</a>')

and you do it in a single pass.

There's some pretty good answers here but I want to elaborate on all topics:

Cloud: shailesh's answer is awesome, nothing to add there! Basically, An application that's served seamlessly over the network can be considered a Cloud application. Cloud isn't a new invention and it's very similar to Grid computing, but it's more of a buzzword with the spike of recent popularity.

Grid: Grid is defined as a large collection as machines connected by a private network and offers a set of services to users, it acts as a sort of supercomputer by sharing processing power across the machines. Source: Tenenbaum, Andrew.

Cluster: A cluster is different from those two. Clusters are two or more computers who share a network connection that acts as a heart-beat. Clusters are configurable in Active-Active or Active-Passive ways. Active-Active being that each computer runs it's own set of services (Say, one runs a SQL instance, the other runs a web server) and they share some resources such as storage. If one of the computers in a cluster goes down the service fails over to the other node and almost seamlessly starts running there. Active-Passive is similar, but only one machine runs these services and only takes over once there's a failure.

The keyboard shortcut cmd-t opens a new tab, so you can pass this keystroke to OSA command as follows:

You can use the following solution to accomplish your goal:

struct student 
{
    char name[20];
    char country[20];
};
void main()
{
    struct student S={"Wolverine","America"};
    struct student X;
    X=S;
    printf("%s%s",X.name,X.country);
}

In symfony >= 3.2, documentation states that:

An alternative way to get the current user in a controller is to type-hint the controller argument with UserInterface (and default it to null if being logged-in is optional):

use Symfony\Component\Security\Core\User\UserInterface\UserInterface;

public function indexAction(UserInterface $user = null)
{
    // $user is null when not logged-in or anon.
}

This is only recommended for experienced developers who don't extend from the Symfony base controller and don't use the ControllerTrait either. Otherwise, it's recommended to keep using the getUser() shortcut.

Blog post about it

• Sometimes when you double click on a warning about the referenced assembly version mismatch between two or more projects you forget to close the assembly view window and it stays there among other tabs... so you end up with the assembly being locked by VS itself and it took me quite a lot of time to figure that out :)

  Be careful with the power VS provides ;)

• Another dummy scenario. Sometimes simply deleting the whole obj folder or just the file warned as the locked one helps out with this crappy error.

Why not just use a step parameter of range function as well to get:

l = range(0, 1000, 10)

For comparison, on my machine:

H:\>python -m timeit -s "l = range(1000)" "l1 = [x for x in l if x % 10 == 0]"
10000 loops, best of 3: 90.8 usec per loop
H:\>python -m timeit -s "l = range(1000)" "l1 = l[0::10]"
1000000 loops, best of 3: 0.861 usec per loop
H:\>python -m timeit -s "l = range(0, 1000, 10)"
100000000 loops, best of 3: 0.0172 usec per loop

In the new ES2015 standard for JavaScript (formerly called ES6), objects can be created with computed keys: Object Initializer spec.

The syntax is:

var obj = {
  [myKey]: value,
}

If applied to the OP's scenario, it would turn into:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    return {
      [this.attr('name')]: this.attr('value'),
    };
  }) 

  callback(null, inputs);
}

Note: A transpiler is still required for browser compatiblity.

Using Babel or Google's traceur, it is possible to use this syntax today.

In earlier JavaScript specifications (ES5 and below), the key in an object literal is always interpreted literally, as a string.

To use a "dynamic" key, you have to use bracket notation:

var obj = {};
obj[myKey] = value;

In your case:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    var key   = this.attr('name')
     ,  value = this.attr('value')
     ,  ret   = {};

     ret[key] = value;
     return ret;
  }) 

  callback(null, inputs);
}

I know this is an old answer but here is what I usually do:

CSS:

.form-control-inline {
   width: auto;
   float:left;
   margin-right: 5px;
}

Then wrap the fields you want to be inlined in a div and add .form-control-inline to the input, example:

HTML

<label class="control-label">Date of birth:</label>
<div>
<select class="form-control form-control-inline" name="year"> ... </select>
<select class="form-control form-control-inline" name="month"> ... </select>
<select class="form-control form-control-inline" name="day"> ... </select>
</div>

You can also use Json.NET.

return JsonConvert.SerializeObject(jsonResult.Data);

Datatables supports HTML5 data-* attributes for this functionality.

It supports multiple columns in the sort order (it's 0-based)

<table data-order="[[ 1, 'desc' ], [2, 'asc' ]]">
    <thead>
        <tr>
            <td>First</td>
            <td>Another column</td>
            <td>A third</td>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>z</td>
            <td>1</td>
            <td>$%^&*</td>
        </tr>
        <tr>
            <td>y</td>
            <td>2</td>
            <td>*$%^&</td>
        </tr>
    </tbody>
</table>

Now my jQuery is simply $('table').DataTables(); and I get my second and third columns sorted in desc / asc order.

Here's some other nice attributes for the <table> that I find myself reusing:

data-page-length="-1" will set the page length to All (pass 25 for page length 25)...

data-fixed-header="true" ... Make a guess

Use the FULL path to the folder in your If Not Exist code. Then you won't even have to CD anymore:

If Not Exist "C:\Documents and Settings\John\Start Menu\Programs\SoftWareFolder\"

From my recent experience i would recommend ksoap library to consume a Soap WCF Service, its actually really easy, this anddev thread migh help you out too.

iOS 8 has changed notification registration in a non-backwards compatible way. While you need to support iOS 7 and 8 (and while apps built with the 8 SDK aren't accepted), you can check for the selectors you need and conditionally call them correctly for the running version.

Here's a category on UIApplication that will hide this logic behind a clean interface for you that will work in both Xcode 5 and Xcode 6.

Header:

//Call these from your application code for both iOS 7 and 8
//put this in the public header
@interface UIApplication (RemoteNotifications)

- (BOOL)pushNotificationsEnabled;
- (void)registerForPushNotifications;

@end

Implementation:

//these declarations are to quiet the compiler when using 7.x SDK
//put this interface in the implementation file of this category, so they are
//not visible to any other code.
@interface NSObject (IOS8)

- (BOOL)isRegisteredForRemoteNotifications;
- (void)registerForRemoteNotifications;

+ (id)settingsForTypes:(NSUInteger)types categories:(NSSet*)categories;
- (void)registerUserNotificationSettings:(id)settings;

@end

@implementation UIApplication (RemoteNotifications)

- (BOOL)pushNotificationsEnabled
{
    if ([self respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
    {
        return [self isRegisteredForRemoteNotifications];
    }
    else
    {
        return ([self enabledRemoteNotificationTypes] & UIRemoteNotificationTypeAlert);
    }
}

- (void)registerForPushNotifications
{
    if ([self respondsToSelector:@selector(registerForRemoteNotifications)])
    {
        [self registerForRemoteNotifications];

        Class uiUserNotificationSettings = NSClassFromString(@"UIUserNotificationSettings");

        //If you want to add other capabilities than just banner alerts, you'll need to grab their declarations from the iOS 8 SDK and define them in the same way.
        NSUInteger UIUserNotificationTypeAlert   = 1 << 2;

        id settings = [uiUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert categories:[NSSet set]];            
        [self registerUserNotificationSettings:settings];

    }
    else
    {
        [self registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert];
    }
}

@end

You can't do this safely. You can cheat, but then your program is broken and this will inevitably come back to bite someone (it should be you, but often our cheating blows up on someone else.)

Here's a slightly safer way to do it (but I still don't recommend this.)

class WrappedException extends RuntimeException {
    Throwable cause;

    WrappedException(Throwable cause) { this.cause = cause; }
}

static WrappedException throwWrapped(Throwable t) {
    throw new WrappedException(t);
}

try 
    source.stream()
          .filter(e -> { ... try { ... } catch (IOException e) { throwWrapped(e); } ... })
          ...
}
catch (WrappedException w) {
    throw (IOException) w.cause;
}

Here, what you're doing is catching the exception in the lambda, throwing a signal out of the stream pipeline that indicates that the computation failed exceptionally, catching the signal, and acting on that signal to throw the underlying exception. The key is that you are always catching the synthetic exception, rather than allowing a checked exception to leak out without declaring that exception is thrown.

if you are using windows os and believe that skype is not the suspect, then you might want to check the task manager and check the "Show processes from all users" and make sure that there is NO entry for httpd.exe. Otherwise, end its process. That solves my problem.

I just so happen to be in the process of yanking out home grown DI code and replacing it with an IOC. I have probably removed well over 200 lines of code and replaced it with about 10. Yes, I had to do a little bit of learning on how to use the container (Winsor), but I'm an engineer working on internet technologies in the 21st century so I'm used to that. I probably spent about 20 minutes looking over the how tos. This was well worth my time.

One (quick & dirty) way to resize images it to use HTML & specify the new size in the image element. This even works for animated images with transparency.

Use the vectorised str method replace:

In [30]:

df['range'] = df['range'].str.replace(',','-')
df
Out[30]:
      range
0    (2-30)
1  (50-290)

EDIT

So if we look at what you tried and why it didn't work:

df['range'].replace(',','-',inplace=True)

from the docs we see this desc:

str or regex: str: string exactly matching to_replace will be replaced with value

So because the str values do not match, no replacement occurs, compare with the following:

In [43]:

df = pd.DataFrame({'range':['(2,30)',',']})
df['range'].replace(',','-', inplace=True)
df['range']
Out[43]:
0    (2,30)
1         -
Name: range, dtype: object

here we get an exact match on the second row and the replacement occurs.

const mapObject = (obj = {}, mapper) =>
  Object.entries(obj).reduce(
    (acc, [key, val]) => ({ ...acc, [key]: mapper(val) }),
    {},
  );

Be careful in comparing the find result with the the end like for map 'm' as all answer have done above map::iterator i = m.find("f");

 if (i == m.end())
 {
 }
 else
 {
 }  

you should not try and perform any operation such as printing the key or value with iterator i if its equal to m.end() else it will lead to segmentation fault.

If you cannot modify your php.ini configuration, you could as well use the following snippet at the beginning of your code:

date_default_timezone_set('Africa/Lagos');//or change to whatever timezone you want

The list of timezones can be found at http://www.php.net/manual/en/timezones.php.

I have slightly modified the jangorecki function for the case where we may have a variety of values that cannot be converted to a number. In my function, a template search is performed and if the template is not found, FALSE is returned.! before gperl, it means that we need those vector elements that do not match the template. The rest is similar to the as.num function. Example:

as.num.pattern <- function(x, pattern){
  stopifnot(is.character(x))
  na = !grepl(pattern, x)
  x[na] = -Inf
  x = as.numeric(x)
  x[na] = NA_real_
  x
}

as.num.pattern(c('1', '2', '3.43', 'char1', 'test2', 'other3', '23/40', '23, 54 cm.'))

[1] 1.00 2.00 3.43   NA   NA   NA   NA   NA

The above answers work for many cases but they miss some. Consider the following:

fl = sum([0.1]*10)  # this is 0.9999999999999999, but we want to say it IS an int

Using this as a benchmark, some of the other suggestions don't get the behavior we might want:

fl.is_integer() # False

fl % 1 == 0     # False

Instead try:

def isclose(a, b, rel_tol=1e-09, abs_tol=0.0):
    return abs(a-b) <= max(rel_tol * max(abs(a), abs(b)), abs_tol)

def is_integer(fl):
    return isclose(fl, round(fl))

now we get:

is_integer(fl)   # True

isclose comes with Python 3.5+, and for other Python's you can use this mostly equivalent definition (as mentioned in the corresponding PEP)

The official way to find out if you have 4.5 installed (and not 4.0) is in the registry keys :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

Relesae DWORD needs to be bigger than 378675 Here is the Microsoft doc for it

all the other answers of checking the minor version after 4.0.30319.xxxxx seem correct though (msbuild.exe -version , or properties of clr.dll), i just needed something documented (not a blog)

    private void BindDataBInfo()
    {
        System.Web.HttpBrowserCapabilities browser = Request.Browser;
        Literal1.Text = "<table border=\"1\" cellspacing=\"3\" cellpadding=\"2\">";
        foreach (string key in browser.Capabilities.Keys)
        {
            Literal1.Text += "<tr><td>" + key + "</td><td>" + browser[key] + "</tr>";
        }
        Literal1.Text += "</table>";
        browser = null;
    }

It's easy to do:

select 
    CASE WHEN 10 > 1 THEN 'Yes'
    ELSE 'No'
END 

The best way I have found is to either check for a method on the string, i.e.:

if (x.substring) {
// do string thing
} else{
// do other thing
}

or if you want to do something with the number check for a number property,

if (x.toFixed) {
// do number thing
} else {
// do other thing
}

This is sort of like "duck typing", it's up to you which way makes the most sense. I don't have enough karma to comment, but typeof fails for boxed strings and numbers, i.e.:

alert(typeof new String('Hello World'));
alert(typeof new Number(5));

will alert "object".

Here is an example on how to use the onClickListener in Kotlin

button1.setOnClickListener(object : View.OnClickListener{
            override fun onClick(v: View?) {
                //Your code here
            }})

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

This may help you as well. This is a conditional statement that will fill the cell with a default date if it is empty but will subtract one hour if it is a valid date/time and put it into the cell.

=IF((Sheet1!C4)="",DATE(1999,1,1),Sheet1!C4-TIME(1,0,0))

You can also substitute TIME with DATE to add or subtract a date or time.

It sets the default collation for the table; if you create a new column, that should be collated with latin_general_ci -- I think. Try specifying the collation for the individual column and see if that works. MySQL has some really bizarre behavior in regards to the way it handles this.
