Here's a complete solution for Swagger with Spring Security. We probably want to only enable Swagger in our development and QA environment and disable it in the production environment. So, I am using a property (prop.swagger.enabled) as a flag to bypass spring security authentication for swagger-ui only in development/qa environment.

@Configuration
@EnableSwagger2
public class SwaggerConfiguration extends WebSecurityConfigurerAdapter implements WebMvcConfigurer {

@Value("${prop.swagger.enabled:false}")
private boolean enableSwagger;

@Bean
public Docket SwaggerConfig() {
    return new Docket(DocumentationType.SWAGGER_2)
            .enable(enableSwagger)
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.your.controller"))
            .paths(PathSelectors.any())
            .build();
}

@Override
public void configure(WebSecurity web) throws Exception {
    if (enableSwagger)  
        web.ignoring().antMatchers("/v2/api-docs",
                               "/configuration/ui",
                               "/swagger-resources/**",
                               "/configuration/security",
                               "/swagger-ui.html",
                               "/webjars/**");
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    if (enableSwagger) {
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
  }
}

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

Since security.disable option is banned from usage there is still a way to achieve it from pure config without touching any class flies (for me it creates convenience with environments manipulation and possibility to activate it with ENV variable) if you use Boot

spring.autoconfigure.exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

One way to print your code is to push it to an online version control system like Github or Bitbucket. In your browser, navigate to the file and print it.

Doing it this way, you'll get syntax highlighting and version control.

After trying everything I could, I just added "autoWidth": true and it worked for me.

You can do this with numpy's argsort method if you have numpy available:

>>> import numpy
>>> vals = numpy.array([2,3,1,4,5])
>>> vals
array([2, 3, 1, 4, 5])
>>> sort_index = numpy.argsort(vals)
>>> sort_index
array([2, 0, 1, 3, 4])

If not available, taken from this question, this is the fastest method:

>>> vals = [2,3,1,4,5]
>>> sorted(range(len(vals)), key=vals.__getitem__)
[2, 0, 1, 3, 4]

Try adding log_errors = Off and check the error_reporting setting whether it's set high enough.

This is an old thread, but I ran into java.net.SocketException: Connection reset yesterday.

The server-side application had its throttling settings changed to allow only 1 connection at a time! Thus, sometimes calls went through and sometimes not. I solved the problem by changing the throttling settings.

Thinking of a string as a set of characters, in mathematics the empty set is always a subset of any set.

With pure JavaScript:

console.log(window.location.href)

Using Angular:

this.router.url

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
    template: 'The href is: {{href}}'
    /*
    Other component settings
    */
})
export class Component {
    public href: string = "";

    constructor(private router: Router) {}

    ngOnInit() {
        this.href = this.router.url;
        console.log(this.router.url);
    }
}

The plunkr is here: https://plnkr.co/edit/0x3pCOKwFjAGRxC4hZMy?p=preview

One-liner

str = str.replace(/^,/, '');

I'll be back.

You might want to try Catel. It allows you to define a DataWindow class (instead of Window), and that class automatically creates the view model for you. This way, you can use the declaration of the ViewModel as you did in your original post, and the view model will still be created and set as DataContext.

See this article for an example.

If you are using atomic, it means the thread will be safe and read-only. If you are using nonatomic, it means the multiple threads access the variable and is thread unsafe, but it is executed fast, done a read and write operations; this is a dynamic type.

You could change your code in this way:

public delegate void CallbackHandler(string str);

public class ServerRequest
{
    public void DoRequest(string request, CallbackHandler callback)
    {
        // do stuff....
        callback("asdf");
    }
}

use ROUND () (See examples ) function in sql server

select round(11.6,0)

result:

12.0

ex2:

select round(11.4,0)

result:

11.0

if you don't want the decimal part, you could do

select cast(round(11.6,0) as int)

You can use the following below with document.title = 'Home Page'

import React from 'react'
import { Component } from 'react-dom'


class App extends Component{
  componentDidMount(){
    document.title = "Home Page"
  }

  render(){
    return(
      <p> Title is now equal to Home Page </p>
    )
  }
}

ReactDOM.render(
  <App />,
  document.getElementById('root')
);

or You can use this npm package npm i react-document-title

import React from 'react'
import { Component } from 'react-dom'
import DocumentTitle from 'react-document-title';


class App extends Component{


  render(){
    return(
      <DocumentTitle title='Home'>
        <h1>Home, sweet home.</h1>
      </DocumentTitle>
    )
  }
}

ReactDOM.render(
  <App />,
  document.getElementById('root')
);

Happy Coding!!!

use this xml change the color with your choice.

<item>
    <layer-list>
        <item>
            <shape>
                <solid android:color="@color/gray_500" />

            </shape>
        </item>
        <!-- CONTENT LAYER -->
        <item android:bottom="2dp" >
            <shape>
                <solid android:color="#ffffff" />
            </shape>
        </item>
    </layer-list>
</item>

In Case if you want programmatically

public static Drawable getStorkLineDrawable(@ColorInt int colorStrok, int    iSize, int left, int top, int right, int bottom)

{
    GradientDrawable gradientDrawable = new GradientDrawable();
    gradientDrawable.setShape(GradientDrawable.RECTANGLE);
    gradientDrawable.setStroke(iSize, colorStrok);
    LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{gradientDrawable});
    layerDrawable.setLayerInset(0, left, top, right, bottom);
    return layerDrawable;
}

call this method like

  Drawable yourLineDrawable=  getStorkLineDrawable(yourColor, iSize, -iSize, -iSize, -iSize, 0);

Setters and Getters apply to computed properties; such properties do not have storage in the instance - the value from the getter is meant to be computed from other instance properties. In your case, there is no x to be assigned.

Explicitly: "How can I do this without explicit backing ivars". You can't - you'll need something to backup the computed property. Try this:

class Point {
  private var _x: Int = 0             // _x -> backingX
  var x: Int {
    set { _x = 2 * newValue }
    get { return _x / 2 }
  }
}

Specifically, in the Swift REPL:

 15> var pt = Point()
pt: Point = {
  _x = 0
}
 16> pt.x = 10
 17> pt
$R3: Point = {
  _x = 20
}
 18> pt.x
$R4: Int = 10

this remove orange frame in chrome from all and any element no matter what and where is it

*:focus {
    outline: none;
}

As the az7ar answer is beautifully said but Let me make it simpler with socket.io rooms. request a server with a unique identifier to join a server. here we are using an email as a unique identifier.

Client Socket.io

socket.on('connect', function () {
  socket.emit('join', {email: [email protected]});
});

When the user joined a server, create a room for that user

Server Socket.io

io.on('connection', function (socket) {
   socket.on('join', function (data) {    
    socket.join(data.email);
  });
});

Now we are all set with joining. let emit something to from the server to room, so that user can listen.

Server Socket.io

io.to('[email protected]').emit('message', {msg: 'hello world.'});

Let finalize the topic with listening to message event to the client side

socket.on("message", function(data) {
  alert(data.msg);
});

The reference from Socket.io rooms

Okay, how about a CSS answer! We use display: table. Then each of the divs are rows, and finally we apply height of 100% to middle 'row' and voilà.

http://jsfiddle.net/NfmX3/3/

body { display: table; }
div { display: table-row; }
#content {
    width:450px; 
    margin:0 auto;
    text-align: center;
    background-color: blue;
    color: white;
    height: 100%;
}

You should try something like this, I am doing this for my project, its a fallback system

//function to get the remote data
function url_get_contents ($url) {
    if (function_exists('curl_exec')){ 
        $conn = curl_init($url);
        curl_setopt($conn, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($conn, CURLOPT_FRESH_CONNECT,  true);
        curl_setopt($conn, CURLOPT_RETURNTRANSFER, 1);
        $url_get_contents_data = (curl_exec($conn));
        curl_close($conn);
    }elseif(function_exists('file_get_contents')){
        $url_get_contents_data = file_get_contents($url);
    }elseif(function_exists('fopen') && function_exists('stream_get_contents')){
        $handle = fopen ($url, "r");
        $url_get_contents_data = stream_get_contents($handle);
    }else{
        $url_get_contents_data = false;
    }
return $url_get_contents_data;
} 

then later you can do like this

$data = url_get_contents("http://www.google.com");
if($data){
//Do Something....
}

You can return a List instead of an array and things gets much simpler.

    public static List<File> listf(String directoryName) {
        File directory = new File(directoryName);

        List<File> resultList = new ArrayList<File>();

        // get all the files from a directory
        File[] fList = directory.listFiles();
        resultList.addAll(Arrays.asList(fList));
        for (File file : fList) {
            if (file.isFile()) {
                System.out.println(file.getAbsolutePath());
            } else if (file.isDirectory()) {
                resultList.addAll(listf(file.getAbsolutePath()));
            }
        }
        //System.out.println(fList);
        return resultList;
    } 

I already had this same issue and I've got the solution writing a container (.divtagABS-container, in your case) absolutely positioned and then relatively positioning the content inside it (.divtagABS, in your case).

Done! The margin-left and margin-right AUTO for your .divtagABS will now work.

The primary flag seems to only work for vagrant ssh for me.

In the past I have used the following method to hack around the issue.

# stage box intended for configuration closely matching production if ARGV[1] == 'stage'     config.vm.define "stage" do |stage|         box_setup stage, \         "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml"     end end 

You could try frameborder=0.

as per 2018, the targetSdkVersion can be set up in your app/build.gradle the following way:

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'

    defaultConfig {
       ...
       targetSdkVersion 26
    }
    ...
}

if you choose 26 as SDK target, be sure to follow https://developer.android.com/about/versions/oreo/android-8.0-migration

$query_ids = $this->getEntityManager()
      ->createQuery(
        "SELECT e_.id
        FROM MuzichCoreBundle:Element e_
        WHERE [...]
        GROUP BY e_.id")
     ->setMaxResults(5)
     ->setMaxResults($limit) 
    ;

HERE in the second query the result of the first query should be passed ..

$query_select = "SELECT e
      FROM MuzichCoreBundle:Element e 
      WHERE e.id IN (".$query_ids->getResult().")
      ORDER BY e.created DESC, e.name DESC"
    ;


$query = $this->getEntityManager()
      ->createQuery($query_select)
      ->setParameters($params)
      ->setMaxResults($limit);
    ;

$resultCollection = $query->getResult();

<a class="btn btn-large btn-success" id="fire" href="http://twitter.github.io/bootstrap/examples/marketing-narrow.html#">Send Email</a>

})

Slow, ugly, platform-specific... but one-liner ;-)

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web;
using System.Web.Optimization;

namespace CodeRepository.Web
{
    public class BundleConfig
    {
        // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css"));
        }
    }
}

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

A closely related question: How to add reference to System.Web.Optimization for MVC-3-converted-to-4 app

Well.. I found a simpler solution.

String s = comboBox1.Text;

This way I get the selected value as string.

You could do this with JAXB (an implementation is included in Java SE 6).

import java.io.StringReader;
import javax.xml.bind.*;
import javax.xml.transform.stream.StreamSource;

public class Demo {

    public static void main(String[] args) throws Exception {
        String xmlString = "<message>HELLO!</message> ";
        JAXBContext jc = JAXBContext.newInstance(String.class);
        Unmarshaller unmarshaller = jc.createUnmarshaller();
        StreamSource xmlSource = new StreamSource(new StringReader(xmlString));
        JAXBElement<String> je = unmarshaller.unmarshal(xmlSource, String.class);
        System.out.println(je.getValue());
    }

}

Output

HELLO!

use myString.c_str() if you want a c-like string (const char*) to use with printf

thanks

Here's a way:

<html>
    <head>
        <script src="jquery-1.4.2.min.js" type="text/javascript"></script>
        <script type="text/javascript">
            $(document).ready(function(){
                var value = $('input[type="hidden"]')[0].value;
                alert(value.split(/\?/)[1]);
            });
        </script>
    </head>
    <body>
        <input type="hidden" value="/TEST/Name?3" />
    </body>
</html>

I usually use the idiom

Object value = map.get(key);
if (value == null) {
    value = createValue(key);
    map.put(key, value);
}

This means you only hit the map twice if the key is missing

If you want to format it with manually set symbols, use this:

DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(',');
DecimalFormat decimalFormat = new DecimalFormat("#,##0.00", decimalFormatSymbols);
System.out.println(decimalFormat.format(1237516.2548)); //1,237,516.25

Locale-based formatting is preferred, though.

macOs High Sierra

if mysql is not getting started from manager- oxs and have tried direct command i.e

sudo /Applications/XAMPP/bin/mysql.server start

too than go to path edit

/Applications/XAMPP/xamppfiles/etc/

find file :

my.cnf

edit it

under the [mysqld] section, add following line:

innodb_force_recovery = 1

after it save and run or can be done from manager-osx

sudo /Applications/XAMPP/bin/mysql.server start

it should start the mysql.

once its run you need to again edit the

my.cnf

file and remove the line just added

innodb_force_recovery = 1

stop and start mysql again. by command

sudo /Applications/XAMPP/bin/mysql.server start 

or by manager-osx

it will be working fine.

If you want implications, in some scenarios Google Chrome performance is horrible with hardware acceleration enabled. Oddly enough, changing the "trick" to -webkit-transform: rotateZ(360deg); worked just fine.

I don't believe we ever figured out why.

For Java 8 and higher:

    String[] test = {"1", "2", "3", "4", "5"};
    int[] ints = Arrays.stream(test).mapToInt(Integer::parseInt).toArray();

Having html collection of selects you can check if every select has option with specific value and filter those which don't match condition:

//get select collection:
let selects = $('select')
//reduce if select hasn't at least one option with value 1
.filter(function () { return [...this.children].some(el => el.value == 1) });

Take a look at Linq-to-Excel. It's pretty neat.

var book = new LinqToExcel.ExcelQueryFactory(@"File.xlsx");

var query =
    from row in book.Worksheet("Stock Entry")
    let item = new
    {
        Code = row["Code"].Cast<string>(),
        Supplier = row["Supplier"].Cast<string>(),
        Ref = row["Ref"].Cast<string>(),
    }
    where item.Supplier == "Walmart"
    select item;

It also allows for strongly-typed row access too.

People have already mentioned ternary expressions. Sometimes with a simple conditional assignment as your example, it is possible to use a mathematical expression to perform the conditional assignment. This may not make your code very readable, but it does get it on one fairly short line. Your example could be written like this:

x = 2*(i>100) | 1*(i<100)

The comparisons would be True or False, and when multiplying with numbers would then be either 1 or 0. One could use a + instead of an | in the middle.

/x

You can retrieve the elements by name in this version.

say "Month=$+{month} Day=$+{day} Year=$+{year}";

( No attempt has been made to restrict the values for the year. )

Everywhere inside the query string, the wildcard should be ? instead of '?'. That should solve the problem.

EDIT :

To add to that, you need to change date '?' to to_date(?, 'yyyy-mm-dd'). Please try that and let me know.

Element is the only kind of node that can have child nodes and attributes.

Document also has child nodes, BUT
no attributes, no text, exactly one child element.

Here you go:

div{
    display: none;
}

document.querySelector("button").addEventListener("click", function(){
    document.querySelector("div").style.display = "block";
});

<div>blah blah blah</div>
<button>Show</button>

Use the script below, and switch the DatabaseName with then name of the database that you've backed up. On the column physical_device_name, you'll have the full path of your backed-up database:

select a.backup_set_id, a.server_name, a.database_name, a.name, a.user_name, a.position, a.software_major_version, a.backup_start_date, backup_finish_date, a.backup_size, a.recovery_model, b.physical_device_name
from msdb.dbo.backupset a join msdb.dbo.backupmediafamily b
  on a.media_set_id = b.media_set_id
where a.database_name = 'DatabaseName'
order by a.backup_finish_date desc

I have a sample program for this:

public class BrowserBackForward {

/**
 * @param args
 * @throws InterruptedException 
 */
public static void main(String[] args) throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://seleniumhq.org/");
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    //maximize the window
    driver.manage().window().maximize();

    driver.findElement(By.linkText("Documentation")).click();
    System.out.println(driver.getCurrentUrl());
    driver.navigate().back();
    System.out.println(driver.getCurrentUrl());
    Thread.sleep(30000);
    driver.navigate().forward();
    System.out.println("Forward");
    Thread.sleep(30000);
    driver.navigate().refresh();

}

}

An 8-digit hex color value is a representation of ARGB (Alpha, Red, Green, Blue), whereas a 6-digit value just assumes 100% opacity (fully opaque) and defines just the RGB values. So to make this be fully opaque, you can either use #FF555555, or just #555555. Each 2-digit hex value is one byte, representing values from 0-255.

Created a small helper method for cases, where "comment" is always ignored. Less code is easier to read:

public func NSLocalizedString(key: String) -> String {
    return NSLocalizedString(key, comment: "")
}

Just put it anywhere (outside a class) and Xcode will find this global method.

You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.

There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).

You could use the Fisher-Yates Shuffle (code adapted from this site):

function shuffle(array) {
    let counter = array.length;

    // While there are elements in the array
    while (counter > 0) {
        // Pick a random index
        let index = Math.floor(Math.random() * counter);

        // Decrease counter by 1
        counter--;

        // And swap the last element with it
        let temp = array[counter];
        array[counter] = array[index];
        array[index] = temp;
    }

    return array;
}

Try using string.Contains () combined with EndsWith.

var results = from c in db.Customers
              where c.FullName.Contains (FirstName) && c.FullName.EndsWith (LastName)
              select c;

I found the answer to use double and triple quotation marks unsatisfactory. I used a nested DO...LOOP to write an ASP segment of code. There are repeated quotation marks within the string. When I ran the code:

thestring = "<asp:RectangleHotSpot Bottom=""" & bottom & """ HotSpotMode=""PostBack"" Left="""& left & """    PostBackValue=""" &xx & "." & yy & """ Right=""" & right & """ Top=""" & top & """/>"

the output was: <`asp:RectangleHotSpot Bottom="28

 'Changing the code to the explicit chr() call worked:

thestring = "<asp:RectangleHotSpot Bottom=""" & bottom & chr(34) & " HotSpotMode=""PostBack"" Left="""& left & chr(34) & " PostBackValue=""" &xx & "." & yy & chr(34) & " Right=""" & right & chr(34) & " Top=""" & top & chr(34) &"/>"

The output:

<asp:RectangleHotSpot Bottom="28" HotSpotMode="PostBack" Left="0" PostBackValue="0.0" Right="29" Top="0"/>

You simply don't call the function.

>>>def x():
>>>    print(20)
>>>y = x
>>>y()
20

The brackets tell python that you are calling the function, so when you put them there, it calls the function and assigns y the value returned by x (which in this case is None).

Why should you learn Python Programming Language?

Python offers a stepping stone into the world of programming. Even though Python Programming Language has been around for 25 years, it is still rising in popularity. Some of the biggest advantage of Python are it's

• Easy to Read & Easy to Learn
• Very productive or small as well as big projects
• Big libraries for many things

What is Python Programming Language used for?

As a general purpose programming language, Python can be used for multiple things. Python can be easily used for small, large, online and offline projects. The best options for utilizing Python are web development, simple scripting and data analysis. Below are a few examples of what Python will let you do:

Web Development:

You can use Python to create web applications on many levels of complexity. There are many excellent Python web frameworks including, Pyramid, Django and Flask, to name a few.

Data Analysis:

Python is the leading language of choice for many data scientists. Python has grown in popularity, within this field, due to its excellent libraries including; NumPy and Pandas and its superb libraries for data visualisation like Matplotlib and Seaborn.

Machine Learning:

What if you could predict customer satisfaction or analyse what factors will affect household pricing or to predict stocks over the next few days, based on previous years data? There are many wonderful libraries implementing machine learning algorithms such as Scikit-Learn, NLTK and TensorFlow.

Computer Vision:

You can do many interesting things such as Face detection, Color detection while using Opencv and Python.

Internet Of Things With Raspberry Pi:

Raspberry Pi is a very tiny and affordable computer which was developed for education and has gained enormous popularity among hobbyists with do-it-yourself hardware and automation. You can even build a robot and automate your entire home. Raspberry Pi can be used as the brain for your robot in order to perform various actions and/or react to the environment. The coding on a Raspberry Pi can be performed using Python. The Possibilities are endless!

Game Development:

Create a video game using module Pygame. Basically, you use Python to write the logic of the game. PyGame applications can run on Android devices.

Web Scraping:

If you need to grab data from a website but the site does not have an API to expose data, use Python to scraping data.

Writing Scripts:

If you're doing something manually and want to automate repetitive stuff, such as emails, it's not difficult to automate once you know the basics of this language.

Browser Automation:

Perform some neat things such as opening a browser and posting a Facebook status, you can do it with Selenium with Python.

GUI Development:

Build a GUI application (desktop app) using Python modules Tkinter, PyQt to support it.

Rapid Prototyping:

Python has libraries for just about everything. Use it to quickly built a (lower-performance, often less powerful) prototype. Python is also great for validating ideas or products for established companies and start-ups alike.

Python can be used in so many different projects. If you're a programmer looking for a new language, you want one that is growing in popularity. As a newcomer to programming, Python is the perfect choice for learning quickly and easily.

You could place the link within a div, then use JavaScript on the anchor tag to hide the div when clicked. Example (not tested, may need to be tweaked but you get the idea):

<div id="printOption">
    <a href="javascript:void();" 
       onclick="document.getElementById('printOption').style.visibility = 'hidden'; 
       document.print(); 
       return true;">
       Print
    </a>
</div>

The downside is that once clicked, the button disappears and they lose that option on the page (there's always Ctrl+P though).

The better solution would be to create a print stylesheet and within that stylesheet specify the hidden status of the printOption ID (or whatever you call it). You can do this in the head section of the HTML and specify a second stylesheet with a media attribute.

The mandelbrot set is generated by repeatedly evaluating a function until it overflows (some defined limit), then checking how long it took you to overflow.

Pseudocode:

MAX_COUNT = 64 // if we haven't escaped to infinity after 64 iterations, 
               // then we're inside the mandelbrot set!!!

foreach (x-pixel)
  foreach (y-pixel)
    calculate x,y as mathematical coordinates from your pixel coordinates
    value = (x, y)
    count = 0
    while value.absolutevalue < 1 billion and count < MAX_COUNT
        value = value * value + (x, y)
        count = count + 1

    // the following should really be one statement, but I split it for clarity
    if count == MAX_COUNT 
        pixel_at (x-pixel, y-pixel) = BLACK
    else 
        pixel_at (x-pixel, y-pixel) = colors[count] // some color map. 

Notes:

value is a complex number. a complex number (a+bi) is squared to give (aa-b*b+2*abi). You'll have to use a complex type, or include that calculation in your loop.

In case you want to get the row count in the middle of a chained operation, you can use:

df.pipe(len)

Example:

row_count = (
      pd.DataFrame(np.random.rand(3,4))
      .reset_index()
      .pipe(len)
)

This can be useful if you don't want to put a long statement inside a len() function.

You could use __len__() instead but __len__() looks a bit weird.

Just to clearify: man-page of sed on OSX (10.8; Darwin Kernel Version 12.4.0) says:

[...]

Sed Regular Expressions

 The regular expressions used in sed, by default, are basic regular expressions (BREs, see re_format(7) for more information), but extended
 (modern) regular expressions can be used instead if the -E flag is given.  In addition, sed has the following two additions to regular
 expressions:

 1.   In a context address, any character other than a backslash (``\'') or newline character may be used to delimit the regular expression.
      Also, putting a backslash character before the delimiting character causes the character to be treated literally.  For example, in the
      context address \xabc\xdefx, the RE delimiter is an ``x'' and the second ``x'' stands for itself, so that the regular expression is
      ``abcxdef''.

 2.   The escape sequence \n matches a newline character embedded in the pattern space.  You cannot, however, use a literal newline charac-
      ter in an address or in the substitute command.

[...]

so I guess one have to use tr - as mentioned above - or the nifty

sed "s/,/^M
/g"

note: you have to type <ctrl>-v,<return> to get '^M' in vi editor

Your query translates to

SELECT * FROM table WHERE id='1' or id='2' or id='3' or id='4';

It will only return the results that match it.

One way of solving it avoiding the complexity would be, chaning the datatype to SET. Then you could use, FIND_IN_SET

SELECT * FROM table WHERE FIND_IN_SET('1', id);

Download last version (not 2.5.1 or other old ones) from jmeter.apache.org

Unzip file

Ensure you install a version of JAVA which is compatible, Java 6 or 7 for JMeter 2.11

In bin folder click on jmeter.sh not on jar or execute sh ./apache-jmeter-x.x.x/bin/jmeter in the terminal.

x.x.x is the version you use.

Finally, when started you may want to select System Look and feel for Mac OSX better integration. Menu > Options > Look and Feel > System

Thanks, this was very helpful. I also wanted something that would link things that looked like a URL -- as a basic requirement, it'd link something like www.yahoo.com, even if the http:// protocol prefix was not present. So basically, if "www." is present, it'll link it and assume it's http://. I also wanted emails to turn into mailto: links. EXAMPLE: www.yahoo.com would be converted to www.yahoo.com

Here's the code I ended up with (combination of code from this page and other stuff I found online, and other stuff I did on my own):

function Linkify(inputText) {
    //URLs starting with http://, https://, or ftp://
    var replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim;
    var replacedText = inputText.replace(replacePattern1, '<a href="$1" target="_blank">$1</a>');

    //URLs starting with www. (without // before it, or it'd re-link the ones done above)
    var replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim;
    var replacedText = replacedText.replace(replacePattern2, '$1<a href="http://$2" target="_blank">$2</a>');

    //Change email addresses to mailto:: links
    var replacePattern3 = /(\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,6})/gim;
    var replacedText = replacedText.replace(replacePattern3, '<a href="mailto:$1">$1</a>');

    return replacedText
}

In the 2nd replace, the (^|[^/]) part is only replacing www.whatever.com if it's not already prefixed by // -- to avoid double-linking if a URL was already linked in the first replace. Also, it's possible that www.whatever.com might be at the beginning of the string, which is the first "or" condition in that part of the regex.

This could be integrated as a jQuery plugin as Jesse P illustrated above -- but I specifically wanted a regular function that wasn't acting on an existing DOM element, because I'm taking text I have and then adding it to the DOM, and I want the text to be "linkified" before I add it, so I pass the text through this function. Works great.

Since I've updated to Android Oreo, I had to use this script to fix 'permission denied' issue.

This script on Mac OS X will copy your db file to Desktop. Just change it to match your ADB_PATH, DESTINATION_PATH and PACKAGE NAME.

#!/bin/sh
ADB_PATH="/Users/xyz/Library/Android/sdk/platform-tools"
PACKAGE_NAME="com.example.android"
DB_NAME="default.realm"
DESTINATION_PATH="/Users/xyz/Desktop/${DB_NAME}"
NOT_PRESENT="List of devices attached"
ADB_FOUND=`${ADB_PATH}/adb devices | tail -2 | head -1 | cut -f 1 | sed 's/ *$//g'`
if [[ ${ADB_FOUND} == ${NOT_PRESENT} ]]; then
    echo "Make sure a device is connected"
else
     ${ADB_PATH}/adb exec-out run-as ${PACKAGE_NAME} cat files/${DB_NAME} > ${DESTINATION_PATH}
fi

Is there a way to have placeholders, like ? for column names? For example SELECT ? FROM TABLEA GROUP BY ?

Use dynamic query as below:

String queryString = "SELECT "+ colName+ " FROM TABLEA GROUP BY "+ colName;

If I want to simply run the above query and get a List what is the best way?

List<String> data = getJdbcTemplate().query(query, new RowMapper<String>(){
                            public String mapRow(ResultSet rs, int rowNum) 
                                                         throws SQLException {
                                    return rs.getString(1);
                            }
                       });

EDIT: To Stop SQL Injection, check for non word characters in the colName as :

          Pattern pattern = Pattern.compile("\\W");
          if(pattern.matcher(str).find()){
               //throw exception as invalid column name
          }

If you want a UTF8 string, where every byte is correct ('Ö' -> [195, 0] , [150, 0]), you can use the followed:

public static string Utf16ToUtf8(string utf16String)
{
   /**************************************************************
    * Every .NET string will store text with the UTF16 encoding, *
    * known as Encoding.Unicode. Other encodings may exist as    *
    * Byte-Array or incorrectly stored with the UTF16 encoding.  *
    *                                                            *
    * UTF8 = 1 bytes per char                                    *
    *    ["100" for the ansi 'd']                                *
    *    ["206" and "186" for the russian '?']                   *
    *                                                            *
    * UTF16 = 2 bytes per char                                   *
    *    ["100, 0" for the ansi 'd']                             *
    *    ["186, 3" for the russian '?']                          *
    *                                                            *
    * UTF8 inside UTF16                                          *
    *    ["100, 0" for the ansi 'd']                             *

    * We can use the convert encoding function to convert an     *
    * UTF16 Byte-Array to an UTF8 Byte-Array. When we use UTF8   *

    *                                                            *
    * So we imitate UTF16 by filling the second byte of a char   *
    * with a 0 byte (binary 0) while creating the string.        *
    **************************************************************/

    // Storage for the UTF8 string
    string utf8String = String.Empty;

    // Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
    byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
    byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);

    // Fill UTF8 bytes inside UTF8 string
    for (int i = 0; i < utf8Bytes.Length; i++)
    {
        // Because char always saves 2 bytes, fill char with 0
        byte[] utf8Container = new byte[2] { utf8Bytes[i], 0 };
        utf8String += BitConverter.ToChar(utf8Container, 0);
    }

    // Return UTF8
    return utf8String;
}

In my case the DLL request is a UTF8 string too, but unfortunately the UTF8 string must be interpreted with UTF16 encoding ('Ö' -> [195, 0], [19, 32]). So the ANSI '–' which is 150 has to be converted to the UTF16 '–' which is 8211. If you have this case too, you can use the following instead:

public static string Utf16ToUtf8(string utf16String)
{
    // Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
    byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
    byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);

    // Return UTF8 bytes as ANSI string
    return Encoding.Default.GetString(utf8Bytes);
}

Or the Native-Method:

[DllImport("kernel32.dll")]
private static extern Int32 WideCharToMultiByte(UInt32 CodePage, UInt32 dwFlags, [MarshalAs(UnmanagedType.LPWStr)] String lpWideCharStr, Int32 cchWideChar, [Out, MarshalAs(UnmanagedType.LPStr)] StringBuilder lpMultiByteStr, Int32 cbMultiByte, IntPtr lpDefaultChar, IntPtr lpUsedDefaultChar);

public static string Utf16ToUtf8(string utf16String)
{
    Int32 iNewDataLen = WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, utf16String.Length, null, 0, IntPtr.Zero, IntPtr.Zero);
    if (iNewDataLen > 1)
    {
        StringBuilder utf8String = new StringBuilder(iNewDataLen);
        WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, -1, utf8String, utf8String.Capacity, IntPtr.Zero, IntPtr.Zero);

        return utf8String.ToString();
    }
    else
    {
        return String.Empty;
    }
}

If you need it the other way around, see Utf8ToUtf16. Hope I could be of help.

FORCE_INDEX is going to be deprecated after MySQL 8:

Thus, you should expect USE INDEX, FORCE INDEX, and IGNORE INDEX to be deprecated in 
a future release of MySQL, and at some time thereafter to be removed altogether.

https://dev.mysql.com/doc/refman/8.0/en/index-hints.html

You should be using JOIN_INDEX, GROUP_INDEX, ORDER_INDEX, and INDEX instead, for v8.

Check this.

You can't access form inputs via their name. Use document.getElements methods instead.

You can use reference type in generic arguments, not primitive type. So here you should use

Map<String, Integer> myMap = new HashMap<String, Integer>();

and store value as

myMap.put("abc", 5);

use style instead like

<div style="display:none;"></div>

I believe the browser will use the local date format. Don't think it's possible to change. You could of course use a custom date picker.

I believe that if you download the offline ISO image file, and use that to install Visual Studio Express, you won't have to register.

Go here and find the link that says "All - Offline Install ISO image file". Click on it to expand it, select your language, and then click "Download".

Otherwise, it's possible that online registration is simply down for a while, as the error message indicates. You have 30 days before it expires, so give it a few days before starting to panic.

You can find and kill the running processes: ps aux | grep puma Then you can kill it with kill PID

For the lazy and the learning, to put it into your theme, Rfvgyhn's full code

<?php $category = get_the_category();
$firstCategory = $category[0]->cat_name; echo $firstCategory;?>

You have two ways:

First go to the particular path of Android SDK:

1) Open your command prompt and traverse to the platform-tools directory through it such as

$ cd Frameworks\Android-Sdk\platform-tools

2) Run your adb commands now such as to know that your adb is working properly :

$ adb devices OR adb logcat OR simply adb

Second way is :

1) Right click on your My Computer.

2) Open Environment variables.

3) Add new variable to your System PATH variable(Add if not exist otherwise no need to add new variable if already exist).

4) Add path of platform-tools directory to as value of this variable such as C:\Program Files\android-sdk\platform-tools.

5) Restart your computer once.

6) Now run the above adb commands such adb devices or other adb commands from anywhere in command prompt.

Also on you can fire a command on terminal setx PATH "%PATH%;C:\Program Files\android-sdk\platform-tools"

I had this error and all the configurations mentioned above were correct however I was still getting "The client and service bindings may be mismatched" error.

What resolved my error, was matching the messageEncoding attribute values in the following node of service and client config files. They were different in mine, service was Text and client Mtom. Changing service to Mtom to match client's, resolved the issue.

<configuration>
  <system.serviceModel>
      <bindings>
           <basicHttpBinding>
              <binding name="BasicHttpBinding_IMySevice" ... messageEncoding="Mtom">
              ...
              </binding>
           </basicHttpBinding>
      </bindings>
  </system.serviceModel>
</configuration>

This simulates a tab through a form and gives focus to the next input when the enter key is pressed.

window.onkeypress = function(e) {
    if (e.which == 13) {
        e.preventDefault();
        var inputs = document.getElementsByClassName('input');
        for (var i = 0; i < inputs.length; i++) {
        if (document.activeElement.id == inputs[i].id && i+1 < inputs.length ) {
            inputs[i+1].focus();
            break;   
        }
    }

Just add plt.pyplot.show(), that would be fine.

The best solution is disabling SciView.

You can try this code for converting bytes from packet to a null-terminated string and store to "string" variable for processing.

const int buffer_size = 2048;
// variable for storing buffer as printable HEX string
char data[buffer_size*2];
// receive message from socket
int ret = recvfrom(sock, buffer, sizeofbuffer, 0, reinterpret_cast<SOCKADDR *>(&from), &size);
// bytes converting cycle
for (int i=0,j=0; i<ret; i++,j+=2){ 
    char res[2]; 
    itoa((buffer[i] & 0xFF), res, 16);
        if (res[1] == 0) {
            data[j] = 0x30; data[j+1] = res[0];
        }else {
            data[j] = res[0]; data[j + 1] = res[1];
        }
}
// Null-Terminating the string with converted buffer
data[(ret * 2)] = 0;

When we send message with hex bytes 0x01020E0F, variable "data" had char array with string "01020e0f".

There are 3 different methods depending on what I is my requirement and which version I am using.

Here are the methods..

1) Using Convert

DECLARE @DateTime DATETIME = GETDATE();
--Using Convert
SELECT
    CONVERT(NVARCHAR, @DateTime,120) AS 'myDateTime'
    ,CONVERT(NVARCHAR(10), @DateTime, 120) AS 'myDate'
    ,RIGHT(CONVERT(NVARCHAR, @DateTime, 120),8) AS 'myTime'

2) Using Cast (SQL Server 2008 and beyond)

SELECT
    CAST(@DateTime AS DATETIME2) AS 'myDateTime'
    ,CAST(@DateTime AS DATETIME2(3)) AS 'myDateTimeWithPrecision'
    ,CAST(@DateTime AS DATE) AS 'myDate'
    ,CAST(@DateTime AS TIME) AS 'myTime'
    ,CAST(@DateTime AS TIME(3)) AS 'myTimeWithPrecision'

3) Using Fixed-length character data type

DECLARE @myDateTime NVARCHAR(20) = CONVERT(NVARCHAR, @DateTime, 120);
DECLARE @myDate NVARCHAR(10) = CONVERT(NVARCHAR, @DateTime, 120);

SELECT
    @myDateTime AS 'myDateTime'
    ,@myDate AS 'myDate'

You can pass it as a normal prop: foo={<ComponentOne />}

For example:

const ComponentOne = () => <div>Hello world!</div>
const ComponentTwo = () => (
  <div>
    <div>Hola el mundo!</div>
    <ComponentThree foo={<ComponentOne />} />
  </div>
)
const ComponentThree = ({ foo }) => <div>{foo}</div>

What about :

List myList = new ArrayList(); 
String[] myStringArray = new String[] {"Java", "is", "Cool"}; 

Collections.addAll(myList, myStringArray); 

I found this April 2020 read: https://www.quora.com/Why-is-C-so-slow-compared-to-Python by a real-world programmer with 15+ years of Software Development experience.

It states that C# is slower usually because it is compiled to Common Intermediate Language (CIL) instead of machine code like C++. The CIL is then put through Common Language Runtime (CLR) which outputs machine code. However, if you keep executing C# it will take the output of the machine code and cache it so the machine code is saved for the next execution. All in all, C# can be faster if you execute multiple times since it is in machine code after multiple executions.

There is also comments that a good C++ programmer can do optimizations that can be time consuming that will in end be optimized.

There are three approaches:

1. DECLARE
2. SET -- Microsoft Recommended approach
3. SELECT

Below query details the advantage and disadvantage of each:

-- First way, 
DECLARE @test int = (SELECT 1)
       , @test2 int = (SELECT a from (values (1),(2)) t(a)) -- throws error

-- advantage: declare and set in the same place
-- Disadvantage: can be used only during declaration. cannot be used later

-- Second way
DECLARE @test int  
       , @test2 int 

SET @test = (select 1)
SET @test2 = (SELECT a from (values (1),(2)) t(a)) -- throws error

-- Advantage: ANSI standard. 
-- Disadvantage: cannot set more than one variable at a time

-- Third way
DECLARE @test int, @test2 int 
SELECT @test = (select 1)
      ,@test2 = (SELECT a from (values (1),(2)) t(a)) -- throws error

-- Advantage: Can set more than one variable at a time
-- Disadvantage: Not ANSI standard

If you don't mind installing a package, this should be useful: https://pypi.org/project/pathvalidate/

From https://pypi.org/project/pathvalidate/#sanitize-a-filename:

from pathvalidate import sanitize_filename

fname = "fi:l*e/p\"a?t>h|.t<xt"
print(f"{fname} -> {sanitize_filename(fname)}\n")
fname = "\0_a*b:c<d>e%f/(g)h+i_0.txt"
print(f"{fname} -> {sanitize_filename(fname)}\n")

Output

fi:l*e/p"a?t>h|.t<xt -> filepath.txt
_a*b:c<d>e%f/(g)h+i_0.txt -> _abcde%f(g)h+i_0.txt

string inputString = "2000-02-02";
DateTime dDate;

if (DateTime.TryParse(inputString, out dDate))
{
    String.Format("{0:d/MM/yyyy}", dDate); 
}
else
{
    Console.WriteLine("Invalid"); // <-- Control flow goes here
}

All the public and protected members can be inherited from any class while the default or package members can also be inherited from the class within the same package as that of the superclass. It does not depend whether it is static or non static member.

But it is also true that static member function do not take part in dynamic binding. If the signature of that static method is same in both parent and child class then concept of Shadowing applies, not polymorphism.

Since image is deprecated, you should use varbinary.

per Microsoft (thanks for the link @Christopher)

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

Fixed and variable-length data types for storing large non-Unicode and Unicode character and binary data. Unicode data uses the UNICODE UCS-2 character set.

one liner, without opening ~/.zshrc file

echo -n 'export PATH=~/bin:$PATH' >> ~/.zshrc

or

echo -n 'export PATH=$HOME/bin:$PATH' >> ~/.zshrc

To see the effect, do source ~/.zshrc in the same tab or open a new tab

C:\test>find /c "string" file | find ": 0" 1>nul && echo "execute command here"

jQuery Mobile 1.4 Update:

My original article was intended for old way of page handling, basically everything before jQuery Mobile 1.4. Old way of handling is now deprecated and it will stay active until (including) jQuery Mobile 1.5, so you can still use everything mentioned below, at least until next year and jQuery Mobile 1.6.

Old events, including pageinit don't exist any more, they are replaced with pagecontainer widget. Pageinit is erased completely and you can use pagecreate instead, that event stayed the same and its not going to be changed.

If you are interested in new way of page event handling take a look here, in any other case feel free to continue with this article. You should read this answer even if you are using jQuery Mobile 1.4 +, it goes beyond page events so you will probably find a lot of useful information.

Older content:

This article can also be found as a part of my blog HERE.

$(document).on('pageinit') vs $(document).ready()

The first thing you learn in jQuery is to call code inside the $(document).ready() function so everything will execute as soon as the DOM is loaded. However, in jQuery Mobile, Ajax is used to load the contents of each page into the DOM as you navigate. Because of this $(document).ready() will trigger before your first page is loaded and every code intended for page manipulation will be executed after a page refresh. This can be a very subtle bug. On some systems it may appear that it works fine, but on others it may cause erratic, difficult to repeat weirdness to occur.

Classic jQuery syntax:

$(document).ready(function() {

});

To solve this problem (and trust me this is a problem) jQuery Mobile developers created page events. In a nutshell page events are events triggered in a particular point of page execution. One of those page events is a pageinit event and we can use it like this:

$(document).on('pageinit', function() {

});

We can go even further and use a page id instead of document selector. Let's say we have jQuery Mobile page with an id index:

<div data-role="page" id="index">
    <div data-theme="a" data-role="header">
        <h3>
            First Page
        </h3>
        <a href="#second" class="ui-btn-right">Next</a>
    </div>

    <div data-role="content">
        <a href="#" data-role="button" id="test-button">Test button</a>
    </div>

    <div data-theme="a" data-role="footer" data-position="fixed">

    </div>
</div>

To execute code that will only available to the index page we could use this syntax:

$('#index').on('pageinit', function() {

});

Pageinit event will be executed every time page is about be be loaded and shown for the first time. It will not trigger again unless page is manually refreshed or Ajax page loading is turned off. In case you want code to execute every time you visit a page it is better to use pagebeforeshow event.

Here's a working example: http://jsfiddle.net/Gajotres/Q3Usv/ to demonstrate this problem.

Few more notes on this question. No matter if you are using 1 html multiple pages or multiple HTML files paradigm it is advised to separate all of your custom JavaScript page handling into a single separate JavaScript file. This will note make your code any better but you will have much better code overview, especially while creating a jQuery Mobile application.

There's also another special jQuery Mobile event and it is called mobileinit. When jQuery Mobile starts, it triggers a mobileinit event on the document object. To override default settings, bind them to mobileinit. One of a good examples of mobileinit usage is turning off Ajax page loading, or changing default Ajax loader behavior.

$(document).on("mobileinit", function(){
  //apply overrides here
});

Page events transition order

First all events can be found here: http://api.jquerymobile.com/category/events/

Lets say we have a page A and a page B, this is a unload/load order:

1. page B - event pagebeforecreate

2. page B - event pagecreate

3. page B - event pageinit

4. page A - event pagebeforehide

5. page A - event pageremove

6. page A - event pagehide

7. page B - event pagebeforeshow

8. page B - event pageshow

For better page events understanding read this:

• pagebeforeload, pageload and pageloadfailed are fired when an external page is loaded
• pagebeforechange, pagechange and pagechangefailed are page change events. These events are fired when a user is navigating between pages in the applications.
• pagebeforeshow, pagebeforehide, pageshow and pagehide are page transition events. These events are fired before, during and after a transition and are named.
• pagebeforecreate, pagecreate and pageinit are for page initialization.
• pageremove can be fired and then handled when a page is removed from the DOM

Page loading jsFiddle example: http://jsfiddle.net/Gajotres/QGnft/

If AJAX is not enabled, some events may not fire.

Prevent page transition

If for some reason page transition needs to be prevented on some condition it can be done with this code:

$(document).on('pagebeforechange', function(e, data){
    var to = data.toPage,
        from = data.options.fromPage;

    if (typeof to  === 'string') {
        var u = $.mobile.path.parseUrl(to);
        to = u.hash || '#' + u.pathname.substring(1);
        if (from) from = '#' + from.attr('id');

        if (from === '#index' && to === '#second') {
            alert('Can not transition from #index to #second!');
            e.preventDefault();
            e.stopPropagation();

            // remove active status on a button, if transition was triggered with a button
            $.mobile.activePage.find('.ui-btn-active').removeClass('ui-btn-active ui-focus ui-btn');;
        }
    }
});

This example will work in any case because it will trigger at a begging of every page transition and what is most important it will prevent page change before page transition can occur.

Here's a working example:

Prevent multiple event binding/triggering

jQuery Mobile works in a different way than classic web applications. Depending on how you managed to bind your events each time you visit some page it will bind events over and over. This is not an error, it is simply how jQuery Mobile handles its pages. For example, take a look at this code snippet:

$(document).on('pagebeforeshow','#index' ,function(e,data){
    $(document).on('click', '#test-button',function(e) {
        alert('Button click');
    });
});

Working jsFiddle example: http://jsfiddle.net/Gajotres/CCfL4/

Each time you visit page #index click event will is going to be bound to button #test-button. Test it by moving from page 1 to page 2 and back several times. There are few ways to prevent this problem:

Solution 1

Best solution would be to use pageinit to bind events. If you take a look at an official documentation you will find out that pageinit will trigger ONLY once, just like document ready, so there's no way events will be bound again. This is best solution because you don't have processing overhead like when removing events with off method.

Working jsFiddle example: http://jsfiddle.net/Gajotres/AAFH8/

This working solution is made on a basis of a previous problematic example.

Solution 2

Remove event before you bind it:

$(document).on('pagebeforeshow', '#index', function(){
    $(document).off('click', '#test-button').on('click', '#test-button',function(e) {
        alert('Button click');
    });
});

Working jsFiddle example: http://jsfiddle.net/Gajotres/K8YmG/

Solution 3

Use a jQuery Filter selector, like this:

$('#carousel div:Event(!click)').each(function(){
    //If click is not bind to #carousel div do something
});

Because event filter is not a part of official jQuery framework it can be found here: http://www.codenothing.com/archives/2009/event-filter/

In a nutshell, if speed is your main concern then Solution 2 is much better than Solution 1.

Solution 4

A new one, probably an easiest of them all.

$(document).on('pagebeforeshow', '#index', function(){
    $(document).on('click', '#test-button',function(e) {
        if(e.handled !== true) // This will prevent event triggering more than once
        {
            alert('Clicked');
            e.handled = true;
        }
    });
});

Tnx to the sholsinger for this solution: http://sholsinger.com/archive/2011/08/prevent-jquery-live-handlers-from-firing-multiple-times/

pageChange event quirks - triggering twice

Sometimes pagechange event can trigger twice and it does not have anything to do with the problem mentioned before.

The reason the pagebeforechange event occurs twice is due to the recursive call in changePage when toPage is not a jQuery enhanced DOM object. This recursion is dangerous, as the developer is allowed to change the toPage within the event. If the developer consistently sets toPage to a string, within the pagebeforechange event handler, regardless of whether or not it was an object an infinite recursive loop will result. The pageload event passes the new page as the page property of the data object (This should be added to the documentation, it's not listed currently). The pageload event could therefore be used to access the loaded page.

In few words this is happening because you are sending additional parameters through pageChange.

Example:

<a data-role="button" data-icon="arrow-r" data-iconpos="right" href="#care-plan-view?id=9e273f31-2672-47fd-9baa-6c35f093a800&amp;name=Sat"><h3>Sat</h3></a>

To fix this problem use any page event listed in Page events transition order.

Page Change Times

As mentioned, when you change from one jQuery Mobile page to another, typically either through clicking on a link to another jQuery Mobile page that already exists in the DOM, or by manually calling $.mobile.changePage, several events and subsequent actions occur. At a high level the following actions occur:

• A page change process is begun
• A new page is loaded
• The content for that page is “enhanced” (styled)
• A transition (slide/pop/etc) from the existing page to the new page occurs

This is a average page transition benchmark:

Page load and processing: 3 ms

Page enhance: 45 ms

Transition: 604 ms

Total time: 670 ms

*These values are in milliseconds.

So as you can see a transition event is eating almost 90% of execution time.

Data/Parameters manipulation between page transitions

It is possible to send a parameter/s from one page to another during page transition. It can be done in few ways.

Reference: https://stackoverflow.com/a/13932240/1848600

Solution 1:

You can pass values with changePage:

$.mobile.changePage('page2.html', { dataUrl : "page2.html?paremeter=123", data : { 'paremeter' : '123' }, reloadPage : true, changeHash : true });

And read them like this:

$(document).on('pagebeforeshow', "#index", function (event, data) {
    var parameters = $(this).data("url").split("?")[1];;
    parameter = parameters.replace("parameter=","");
    alert(parameter);
});

Example:

index.html

Solution 2:

Or you can create a persistent JavaScript object for a storage purpose. As long Ajax is used for page loading (and page is not reloaded in any way) that object will stay active.

var storeObject = {
    firstname : '',
    lastname : ''
}

Example: http://jsfiddle.net/Gajotres/9KKbx/

Solution 3:

You can also access data from the previous page like this:

$(document).on('pagebeforeshow', '#index',function (e, data) {
    alert(data.prevPage.attr('id'));
});

prevPage object holds a complete previous page.

Solution 4:

As a last solution we have a nifty HTML implementation of localStorage. It only works with HTML5 browsers (including Android and iOS browsers) but all stored data is persistent through page refresh.

if(typeof(Storage)!=="undefined") {
    localStorage.firstname="Dragan";
    localStorage.lastname="Gaic";
}

Example: http://jsfiddle.net/Gajotres/J9NTr/

Probably best solution but it will fail in some versions of iOS 5.X. It is a well know error.

Don’t Use .live() / .bind() / .delegate()

I forgot to mention (and tnx andleer for reminding me) use on/off for event binding/unbinding, live/die and bind/unbind are deprecated.

The .live() method of jQuery was seen as a godsend when it was introduced to the API in version 1.3. In a typical jQuery app there can be a lot of DOM manipulation and it can become very tedious to hook and unhook as elements come and go. The .live() method made it possible to hook an event for the life of the app based on its selector. Great right? Wrong, the .live() method is extremely slow. The .live() method actually hooks its events to the document object, which means that the event must bubble up from the element that generated the event until it reaches the document. This can be amazingly time consuming.

It is now deprecated. The folks on the jQuery team no longer recommend its use and neither do I. Even though it can be tedious to hook and unhook events, your code will be much faster without the .live() method than with it.

Instead of .live() you should use .on(). .on() is about 2-3x faster than .live(). Take a look at this event binding benchmark: http://jsperf.com/jquery-live-vs-delegate-vs-on/34, everything will be clear from there.

Benchmarking:

There's an excellent script made for jQuery Mobile page events benchmarking. It can be found here: https://github.com/jquery/jquery-mobile/blob/master/tools/page-change-time.js. But before you do anything with it I advise you to remove its alert notification system (each “change page” is going to show you this data by halting the app) and change it to console.log function.

Basically this script will log all your page events and if you read this article carefully (page events descriptions) you will know how much time jQm spent of page enhancements, page transitions ....

Final notes

Always, and I mean always read official jQuery Mobile documentation. It will usually provide you with needed information, and unlike some other documentation this one is rather good, with enough explanations and code examples.

Changes:

• 30.01.2013 - Added a new method of multiple event triggering prevention
• 31.01.2013 - Added a better clarification for chapter Data/Parameters manipulation between page transitions
• 03.02.2013 - Added new content/examples to the chapter Data/Parameters manipulation between page transitions
• 22.05.2013 - Added a solution for page transition/change prevention and added links to the official page events API documentation
• 18.05.2013 - Added another solution against multiple event binding

$sUrl = 'http://www.linktopage.com/login/';
$params = array('http' => array(
    'method'  => 'POST',
    'content' => 'username=admin195&password=d123456789'
));

$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if(!$fp) {
    throw new Exception("Problem with $sUrl, $php_errormsg");
}

$response = @stream_get_contents($fp);
if($response === false) {
    throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}

This format worked for me, for the mentioned date format i.e. MM/DD/YYYY

SELECT to_char(query_date,'MM/DD/YYYY') as query_date 
FROM QMS_INVOICE_TABLE;

Try this:

return( (str).Remove(str.Length-1) );

Use two single-quotes

SQL> SELECT 'D''COSTA' name FROM DUAL;

NAME
-------
D'COSTA

Alternatively, use the new (10g+) quoting method:

SQL> SELECT q'$D'COSTA$' NAME FROM DUAL;

NAME
-------
D'COSTA

In terms of performance related to the main answers these are some online tests.

While the following are some performance tests using console.time() (they work best in your own console, the time is very short to be seen in the snippet)

console.time('split and join');_x000D_
"javascript-test-find-and-replace-all".split('-').join(' ');_x000D_
console.timeEnd('split and join')_x000D_
_x000D_
console.time('regular expression');_x000D_
"javascript-test-find-and-replace-all".replace(new RegExp('-', 'g'), ' ');_x000D_
console.timeEnd('regular expression');_x000D_
_x000D_
console.time('while');_x000D_
let str1 = "javascript-test-find-and-replace-all";_x000D_
while (str1.indexOf('-') !== -1) {_x000D_
    str1 = str1.replace('-', ' ');_x000D_
}_x000D_
console.timeEnd('while');

The interesting thing to notice is that if you run them multiple time the results are always different even though the RegExp solution seems the fastest on average and the while loop solution the slowest.

I couldn't get the accepted answer to work using the Netbeans IDE "Create Table" GUI, and I'm on Netbeans 8.2. To get it to working, create the id column with the following options e.g.

and then use 'New Entity Classes from Database' option to generate the entity for the table (I created a simple table called PERSON with an ID column created exactly as above and a NAME column which is simple varchar(255) column). These generated entities leave it to the user to add the auto generated id mechanism.

GENERATION.AUTO seems to try and use sequences which Derby doesn't seem to like (error stating failed to generate sequence/sequence does not exist), GENERATION.SEQUENCE therefore doesn't work either, GENERATION.IDENTITY doesn't work (get error stating ID is null), so that leaves GENERATION.TABLE.

Set your persistence unit's 'Table Generation Strategy' button to Create. This will create tables that don't exist in the DB when your jar is run (loaded?) i.e. the table your PU needs to create in order to store ID increments. In your entity replace the generated annotations above your id field with the following...

I also created a controller for my entity class using 'JPA Controller Classes from Entity Classes' option. I then create a simple main class to test the id was auto generated i.e.

The result is that the PERSON_ID_TABLE is generated correctly and my PERSON table has two PERSON entries in it with correct, auto generated ids.

Try setting C_INCLUDE_PATH (for C header files) or CPLUS_INCLUDE_PATH (for C++ header files).

As Ciro mentioned, CPATH will set the path for both C and C++ (and any other language).

More details in GCC's documentation.

The only way I able to get this to work was by doing this on the presenting view controller:

    func didTapButton() {
    self.definesPresentationContext = true
    self.modalTransitionStyle = .crossDissolve
    let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "YourViewController") as! YourViewController
    let navController = UINavigationController(rootViewController: yourVC)
    navController.modalPresentationStyle = .overCurrentContext
    navController.modalTransitionStyle = .crossDissolve
    self.present(navController, animated: true, completion: nil)
}

This might be due to the fact that you are trying to add a ListBoxItem with a same name to the page.

If you want to refresh the content of the listbox with the newly retrieved values you will have to first manually remove the content of the listbox other wise your loop will try to create lb_1 again and add it to the same list.

Look at here for a similar problem that occured Silverlight: Value does not fall within the expected range exception

Cheers,

Solution for Swift 4:

yourLabel.layer.borderColor = UIColor.green.cgColor

No, "message" is not forbidden. It's just deprecated. You application will work fine with using message. But you may want to get rid of the deprecation error, of course.

When you create custom Exception classes for your application, many of them do not subclass just from Exception, but from others, like ValueError or similar. Then you have to adapt to their usage of variables.

And if you have many exceptions in your application it's usually a good idea to have a common custom base class for all of them, so that users of your modules can do

try:
    ...
except NelsonsExceptions:
    ...

And in that case you can do the __init__ and __str__ needed there, so you don't have to repeat it for every exception. But simply calling the message variable something else than message does the trick.

In any case, you only need the __init__ or __str__ if you do something different from what Exception itself does. And because if the deprecation, you then need both, or you get an error. That's not a whole lot of extra code you need per class. ;)

Using flexboxes, no javascript, and it is responsive.

Ok, Toast is no complex but it need a context object to work, it could be MyActivity.this, then you can write:

Toast.maketext(MyActivity.this, "Toast text to show", Toast.LENGTH_SHORT).show();

Although Toast is a UI resource, then using it in another thread different to ui thread, will send an error or simply not work If you want to print a variable, put the variable name.toString() and concat that with text you want in the maketext String parameter ;)

I have just found this site – http://unused-css.com/

Looks good but I would need to thoroughly check its outputted 'clean' css before uploading it to any of my sites.

Also as with all these tools I would need to check it didn't strip id's and classes with no style but are used as JavaScript selectors.

The below content is taken from http://unused-css.com/ so credit to them for recommending other solutions:

Latish Sehgal has written a windows application to find and remove unused CSS classes. I haven't tested it but from the description, you have to provide the path of your html files and one CSS file. The program will then list the unused CSS selectors. From the screenshot, it looks like there is no way to export this list or download a new clean CSS file. It also looks like the service is limited to one CSS file. If you have multiple files you want to clean, you have to clean them one by one.

Dust-Me Selectors is a Firefox extension (for v1.5 or later) that finds unused CSS selectors. It extracts all the selectors from all the stylesheets on the page you're viewing, then analyzes that page to see which of those selectors are not used. The data is then stored so that when testing subsequent pages, selectors can be crossed off the list as they're encountered. This tool is supposed to be able to spider a whole website but I unfortunately could make it work. Also, I don't believe you can configure and download the CSS file with the styles removed.

Topstyle is a windows application including a bunch of tools to edit CSS. I haven't tested it much but it looks like it has the ability to removed unused CSS selectors. This software costs 80 USD.

Liquidcity CSS cleaner is a php script that uses regular expressions to check the styles of one page. It will tell you the classes that aren't available in the HTML code. I haven't tested this solution.

Deadweight is a CSS coverage tool. Given a set of stylesheets and a set of URLs, it determines which selectors are actually used and lists which can be "safely" deleted. This tool is a ruby module and will only work with rails website. The unused selectors have to be manually removed from the CSS file.

Helium CSS is a javascript tool for discovering unused CSS across many pages on a web site. You first have to install the javascript file to the page you want to test. Then, you have to call a helium function to start the cleaning.

UnusedCSS.com is web application with an easy to use interface. Type the url of a site and you will get a list of CSS selectors. For each selector, a number indicates how many times a selector is used. This service has a few limitations. The @import statement is not supported. You can't configure and download the new clean CSS file.

CSSESS is a bookmarklet that helps you find unused CSS selectors on any site. This tool is pretty easy to use but it won't let you configure and download clean CSS files. It will only list unused CSS files.

When working with async functions or observables provided by 3rd party libraries, for example Cloud firestore, I've found functions the waitFor method shown below (TypeScript, but you get the idea...) to be helpful when you need to wait on some process to complete, but you don't want to have to embed callbacks within callbacks within callbacks nor risk an infinite loop.

This method is sort of similar to a while (!condition) sleep loop, but yields asynchronously and performs a test on the completion condition at regular intervals till true or timeout.

export const sleep = (ms: number) => {
    return new Promise(resolve => setTimeout(resolve, ms))
}
/**
 * Wait until the condition tested in a function returns true, or until 
 * a timeout is exceeded.
 * @param interval The frenequency with which the boolean function contained in condition is called.
 * @param timeout  The maximum time to allow for booleanFunction to return true
 * @param booleanFunction:  A completion function to evaluate after each interval. waitFor will return true as soon as the completion function returns true.   
 */
export const waitFor = async function (interval: number, timeout: number,
    booleanFunction: Function): Promise<boolean> {
    let elapsed = 1;
    if (booleanFunction()) return true;
    while (elapsed < timeout) {
        elapsed += interval;
        await sleep(interval);
        if (booleanFunction()) {
            return true;
        }
    }
    return false;
}

The say you have a long running process on your backend you want to complete before some other task is undertaken. For example if you have a function that totals a list of accounts, but you want to refresh the accounts from the backend before you calculate, you can do something like this:

async recalcAccountTotals() : number {
     this.accountService.refresh();   //start the async process.
     if (this.accounts.dirty) {
           let updateResult = await waitFor(100,2000,()=> {return !(this.accounts.dirty)})
     }
 if(!updateResult) { 
      console.error("Account refresh timed out, recalc aborted");
      return NaN;
    }
 return ... //calculate the account total. 
}

#This program is to read from excel workbook to fetch only the URL domain names and write to the existing excel workbook in a different sheet..
#Developer - Nilesh K
import pandas as pd
from openpyxl import load_workbook #for writting to the existing workbook

df = pd.read_excel("urlsearch_test.xlsx")

#You can use the below for the relative path.
# r"C:\Users\xyz\Desktop\Python\

l = [] #To make a list in for loop

#begin
#loop starts here for fetching http from a string and iterate thru the entire sheet. You can have your own logic here.
for index, row in df.iterrows():
    try: 
        str = (row['TEXT']) #string to read and iterate
        y = (index)
        str_pos = str.index('http') #fetched the index position for http
        str_pos1 = str.index('/', str.index('/')+2) #fetched the second 3rd position of / starting from http
        str_op = str[str_pos:str_pos1] #Substring the domain name
        l.append(str_op) #append the list with domain names

    #Error handling to skip the error rows and continue.
    except ValueError:
            print('Error!')
print(l)
l = list(dict.fromkeys(l)) #Keep distinct values, you can comment this line to get all the values
df1 = pd.DataFrame(l,columns=['URL']) #Create dataframe using the list
#end

#Write using openpyxl so it can be written to same workbook
book = load_workbook('urlsearch_test.xlsx')
writer = pd.ExcelWriter('urlsearch_test.xlsx',engine = 'openpyxl')
writer.book = book
df1.to_excel(writer,sheet_name = 'Sheet3')
writer.save()
writer.close()

#The below can be used to write to a different workbook without using openpyxl
#df1.to_excel(r"C:\Users\xyz\Desktop\Python\urlsearch1_test.xlsx",index='false',sheet_name='sheet1')

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

Pretty much any time I've created a table without a primary key, thinking I wouldn't need one, I've ended up going back and adding one. I now create even my join tables with an auto-generated identity field that I use as the primary key.

Tested In Angular 7.0.0

Step 1 - Install the required dependencies

npm install bootstrap (if you want specific version please specify the version no.)

npm install popper.js (if you want specific version please specify the version no.)

npm install jquery

Versions I have tried:

"bootstrap": "^4.1.3",
"popper.js": "^1.14.5",
"jquery": "^3.3.1",

Step 2 : Specify the libraries in below orderin angular.json. In latest angular , the config file name is angular.json not angular-cli.json

"architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/client",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
             "node_modules/bootstrap/dist/css/bootstrap.css",
              "src/styles.scss"
            ],
            "scripts": [
              "node_modules/jquery/dist/jquery.min.js",
              "node_modules/popper.js/dist/umd/popper.min.js",
              "node_modules/bootstrap/dist/js/bootstrap.min.js"
            ]
          },

How i resolved this was following the 4th point in this url: https://dev.mysql.com/doc/refman/8.0/en/changing-mysql-user.html

1. Edit my.cnf
2. Add user = root under under [mysqld] group of the file

If this doesn't work then make sure you have changed the password from default.

As simple as:

<template>
    <div id="app">
        <img src="./assets/logo.png">
    </div>
</template>
    
<script>
    export default {
    }
</script>
    
<style lang="css">
</style> 

Taken from the project generated by vue cli.

If you want to use your image as a module, do not forget to bind data to your Vuejs component:

<template>
    <div id="app">
        <img :src="image"/>
    </div>
</template>
    
<script>
    import image from "./assets/logo.png"
    
    export default {
        data: function () {
            return {
                image: image
            }
        }
    }
</script>
    
<style lang="css">
</style>

And a shorter version:

<template>
    <div id="app">
        <img :src="require('./assets/logo.png')"/>
    </div>
</template>
    
<script>
    export default {
    }
</script>
    
<style lang="css">
</style> 

Let Spring 3 injection take care of this.

Thanks to tsunade21 the easiest way is:

 @RequestMapping(method = RequestMethod.GET)   
 public ModelAndView anyMethodNameGoesHere(Principal principal) {
        final String loggedInUserName = principal.getName();

 }

This function will prevent entry of anything other than numbers and a single dot.

   var charCode = (evt.which) ? evt.which : event.keyCode_x000D_

Like taro said, keys returns the array of keys of your Hash:

http://ruby-doc.org/core-1.9.3/Hash.html#method-i-keys

You'll find all the different methods available for each class.

If you don't know what you're dealing with:

 puts my_unknown_variable.class.to_s

This will output the class name.

Normally when an optimization algorithm does not converge, it is usually because the problem is not well-conditioned, perhaps due to a poor scaling of the decision variables. There are a few things you can try.

1. Normalize your training data so that the problem hopefully becomes more well conditioned, which in turn can speed up convergence. One possibility is to scale your data to 0 mean, unit standard deviation using Scikit-Learn's StandardScaler for an example. Note that you have to apply the StandardScaler fitted on the training data to the test data.
2. Related to 1), make sure the other arguments such as regularization weight, C, is set appropriately.
3. Set max_iter to a larger value. The default is 1000.
4. Set dual = True if number of features > number of examples and vice versa. This solves the SVM optimization problem using the dual formulation. Thanks @Nino van Hooff for pointing this out, and @JamesKo for spotting my mistake.
5. Use a different solver, for e.g., the L-BFGS solver if you are using Logistic Regression. See @5ervant's answer.

Note: One should not ignore this warning.

This warning came about because

1. Solving the linear SVM is just solving a quadratic optimization problem. The solver is typically an iterative algorithm that keeps a running estimate of the solution (i.e., the weight and bias for the SVM). It stops running when the solution corresponds to an objective value that is optimal for this convex optimization problem, or when it hits the maximum number of iterations set.

2. If the algorithm does not converge, then the current estimate of the SVM's parameters are not guaranteed to be any good, hence the predictions can also be complete garbage.

Edit

In addition, consider the comment by @Nino van Hooff and @5ervant to use the dual formulation of the SVM. This is especially important if the number of features you have, D, is more than the number of training examples N. This is what the dual formulation of the SVM is particular designed for and helps with the conditioning of the optimization problem. Credit to @5ervant for noticing and pointing this out.

Furthermore, @5ervant also pointed out the possibility of changing the solver, in particular the use of the L-BFGS solver. Credit to him (i.e., upvote his answer, not mine).

I would like to provide a quick rough explanation for those who are interested (I am :)) why this matters in this case. Second-order methods, and in particular approximate second-order method like the L-BFGS solver, will help with ill-conditioned problems because it is approximating the Hessian at each iteration and using it to scale the gradient direction. This allows it to get better convergence rate but possibly at a higher compute cost per iteration. That is, it takes fewer iterations to finish but each iteration will be slower than a typical first-order method like gradient-descent or its variants.

For e.g., a typical first-order method might update the solution at each iteration like

x(k + 1) = x(k) - alpha(k) * gradient(f(x(k)))

where alpha(k), the step size at iteration k, depends on the particular choice of algorithm or learning rate schedule.

A second order method, for e.g., Newton, will have an update equation

x(k + 1) = x(k) - alpha(k) * Hessian(x(k))^(-1) * gradient(f(x(k)))

That is, it uses the information of the local curvature encoded in the Hessian to scale the gradient accordingly. If the problem is ill-conditioned, the gradient will be pointing in less than ideal directions and the inverse Hessian scaling will help correct this.

In particular, L-BFGS mentioned in @5ervant's answer is a way to approximate the inverse of the Hessian as computing it can be an expensive operation.

However, second-order methods might converge much faster (i.e., requires fewer iterations) than first-order methods like the usual gradient-descent based solvers, which as you guys know by now sometimes fail to even converge. This can compensate for the time spent at each iteration.

In summary, if you have a well-conditioned problem, or if you can make it well-conditioned through other means such as using regularization and/or feature scaling and/or making sure you have more examples than features, you probably don't have to use a second-order method. But these days with many models optimizing non-convex problems (e.g., those in DL models), second order methods such as L-BFGS methods plays a different role there and there are evidence to suggest they can sometimes find better solutions compared to first-order methods. But that is another story.

An Error "indicates serious problems that a reasonable application should not try to catch."

while

An Exception "indicates conditions that a reasonable application might want to catch."

Error along with RuntimeException & their subclasses are unchecked exceptions. All other Exception classes are checked exceptions.

Checked exceptions are generally those from which a program can recover & it might be a good idea to recover from such exceptions programmatically. Examples include FileNotFoundException, ParseException, etc. A programmer is expected to check for these exceptions by using the try-catch block or throw it back to the caller

On the other hand we have unchecked exceptions. These are those exceptions that might not happen if everything is in order, but they do occur. Examples include ArrayIndexOutOfBoundException, ClassCastException, etc. Many applications will use try-catch or throws clause for RuntimeExceptions & their subclasses but from the language perspective it is not required to do so. Do note that recovery from a RuntimeException is generally possible but the guys who designed the class/exception deemed it unnecessary for the end programmer to check for such exceptions.

Errors are also unchecked exception & the programmer is not required to do anything with these. In fact it is a bad idea to use a try-catch clause for Errors. Most often, recovery from an Error is not possible & the program should be allowed to terminate. Examples include OutOfMemoryError, StackOverflowError, etc.

Do note that although Errors are unchecked exceptions, we shouldn't try to deal with them, but it is ok to deal with RuntimeExceptions(also unchecked exceptions) in code. Checked exceptions should be handled by the code.

Just assign the import to a data property

<script>
      import json from './json/data.json'
      export default{
          data(){
              return{
                  myJson: json
              }
          }
      }
</script>

then loop through the myJson property in your template using v-for

<template>
    <div>
        <div v-for="data in myJson">{{data}}</div>
    </div>
</template>

NOTE

If the object you want to import is static i.e does not change then assigning it to a data property would make no sense as it does not need to be reactive.

Vue converts all the properties in the data option to getters/setters for the properties to be reactive. So it would be unnecessary and overhead for vue to setup getters/setters for data which is not going to change. See Reactivity in depth.

So you can create a custom option as follows:

<script>
          import MY_JSON from './json/data.json'
          export default{
              //custom option named myJson
                 myJson: MY_JSON
          }
    </script>

then loop through the custom option in your template using $options:

<template>
        <div>
            <div v-for="data in $options.myJson">{{data}}</div>
        </div>
    </template>

Sorting by an ISO formatted date can be expensive, unless you limit the clients to the latest and best browsers, which can create the correct timestamp by Date-parsing the string.

If you are sure of your input, and you know it will always be yyyy-mm-ddThh:mm:ss and GMT (Z) you can extract the digits from each member and compare them like integers

array.sort(function(a,b){
    return a.updated_at.replace(/\D+/g,'')-b.updated_at.replace(/\D+/g,'');
});

If the date could be formatted differently, you may need to add something for iso challenged folks:

Date.fromISO: function(s){
    var day, tz,
    rx=/^(\d{4}\-\d\d\-\d\d([tT ][\d:\.]*)?)([zZ]|([+\-])(\d\d):(\d\d))?$/,
    p= rx.exec(s) || [];
    if(p[1]){
        day= p[1].split(/\D/).map(function(itm){
            return parseInt(itm, 10) || 0;
        });
        day[1]-= 1;
        day= new Date(Date.UTC.apply(Date, day));
        if(!day.getDate()) return NaN;
        if(p[5]){
            tz= (parseInt(p[5], 10)*60);
            if(p[6]) tz+= parseInt(p[6], 10);
            if(p[4]== '+') tz*= -1;
            if(tz) day.setUTCMinutes(day.getUTCMinutes()+ tz);
        }
        return day;
    }
    return NaN;
}
if(!Array.prototype.map){
    Array.prototype.map= function(fun, scope){
        var T= this, L= T.length, A= Array(L), i= 0;
        if(typeof fun== 'function'){
            while(i< L){
                if(i in T){
                    A[i]= fun.call(scope, T[i], i, T);
                }
                ++i;
            }
            return A;
        }
    }
}
}

I want to more fully address the issue of scroll duration, which, should you choose any earlier answer, will in fact will vary dramatically (and unacceptably) according to the amount of scrolling necessary to reach the target position from the current position .

To obtain a uniform scroll duration the velocity (pixels per millisecond) must account for the size of each individual item - and when the items are of non-standard dimension then a whole new level of complexity is added.

This may be why the RecyclerView developers deployed the too-hard basket for this vital aspect of smooth scrolling.

Assuming that you want a semi-uniform scroll duration, and that your list contains semi-uniform items then you will need something like this.

/** Smoothly scroll to specified position allowing for interval specification. <br>
 * Note crude deceleration towards end of scroll
 * @param rv        Your RecyclerView
 * @param toPos     Position to scroll to
 * @param duration  Approximate desired duration of scroll (ms)
 * @throws IllegalArgumentException */
private static void smoothScroll(RecyclerView rv, int toPos, int duration) throws IllegalArgumentException {
    int TARGET_SEEK_SCROLL_DISTANCE_PX = 10000;     // See androidx.recyclerview.widget.LinearSmoothScroller
    int itemHeight = rv.getChildAt(0).getHeight();  // Height of first visible view! NB: ViewGroup method!
    itemHeight = itemHeight + 33;                   // Example pixel Adjustment for decoration?
    int fvPos = ((LinearLayoutManager)rv.getLayoutManager()).findFirstCompletelyVisibleItemPosition();
    int i = Math.abs((fvPos - toPos) * itemHeight);
    if (i == 0) { i = (int) Math.abs(rv.getChildAt(0).getY()); }
    final int totalPix = i;                         // Best guess: Total number of pixels to scroll
    RecyclerView.SmoothScroller smoothScroller = new LinearSmoothScroller(rv.getContext()) {
        @Override protected int getVerticalSnapPreference() {
            return LinearSmoothScroller.SNAP_TO_START;
        }
        @Override protected int calculateTimeForScrolling(int dx) {
            int ms = (int) ( duration * dx / (float)totalPix );
            // Now double the interval for the last fling.
            if (dx < TARGET_SEEK_SCROLL_DISTANCE_PX ) { ms = ms*2; } // Crude deceleration!
            //lg(format("For dx=%d we allot %dms", dx, ms));
            return ms;
        }
    };
    //lg(format("Total pixels from = %d to %d = %d [ itemHeight=%dpix ]", fvPos, toPos, totalPix, itemHeight));
    smoothScroller.setTargetPosition(toPos);
    rv.getLayoutManager().startSmoothScroll(smoothScroller);
}

PS: I curse the day I began indiscriminately converting ListView to RecyclerView.

Same problem fetch main problem in PreparedStatement use simple statement then you successfully insert record same use below.

String  st2="insert into 
user(gender,name,address,telephone,fax,email,
     destination,sdate,edate,Participant,hcategory,
     Culture,Nature,People,Cities,Beaches,Festivals,username,password) 
values('"+gender+"','"+name+"','"+address+"','"+phone+"','"+fax+"',
       '"+email+"','"+desti+"','"+sdate+"','"+edate+"','"+parti+"',
       '"+hotel+"','"+chk1+"','"+chk2+"','"+chk3+"','"+chk4+"',
       '"+chk5+"','"+chk6+"','"+user+"','"+password+"')";


int i=stm.executeUpdate(st2);

Another solution:

public class CountryInfoResponse {
  private List<Object> geonames;
}

Usage of a generic Object-List solved my problem, as there were other Datatypes like Boolean too.

Try:

if [ ! -z `ls /some/dir/*` ]; then echo "huzzah"; fi

I have tried every single solution there was. In the end, this was my problem: when installing the developer certificate I have set it to "Always Trust", when I changed that back to default, it worked. All credit for this goes to: https://blog.supereasyapps.com/how-to-fix-iphone-and-ipad-app-codesign-crashes-using-an-apple-developer-profile/

Use

ls | % {(get-date) - $_.LastWriteTime }

It can work to retrieve the diff. You can replace ls with a single file.

If you were to hardcode it you would use modulus to extract the time as others suggested.

If you are returning the seconds from MySQL database, assuming you don't need the data in seconds format in your app, there is a much cleaner way to do it, you can use MySQL's SEC_TO_TIME and it will return time in hh:mm:ss format.

Eg.

SELECT SEC_TO_TIME(my_seconds_field) AS my_timestring;

I was importing also some projects from VS2010 to VS 2012. I had the same errors. The errors disappeared when I set back Properties > Config. Properties > General > Platform Toolset to v100 (VS2010). That might not be the correct approach, however.

Another option: Do not float your right column; just give it a left margin to move it beyond the float. You'll need a hack or two to fix IE6, but that's the basic idea.

There are four options here:

1. Get virtualenv set up. Each virtual environment you create will automatically have pip.

2. Get pip set up globally.

3. Learn how to install Python packages manually—in most cases it's as simple as download, unzip, python setup.py install, but not always.

4. Use Christoph Gohlke's binary installers.

if you have generic types in your class you should use TypeReference with convertValue().

final ObjectMapper mapper = new ObjectMapper();
final MyPojo<MyGenericType> pojo = mapper.convertValue(map, new TypeReference<MyPojo<MyGenericType>>() {});

Also you can use that to convert a pojo to java.util.Map back.

final ObjectMapper mapper = new ObjectMapper();
final Map<String, Object> map = mapper.convertValue(pojo, new TypeReference<Map<String, Object>>() {});

In my case, the route signature was different from the method parameter. I had id, but I was accepting documentId as parameter, that caused the problem.

[Route("Documents/{id}")]   <--- caused the webapi error
[Route("Documents/{documentId}")] <-- solved
public Document Get(string documentId)
{
  ..
}

I just figured this out in Haskell:

lcm' :: Integral a => a -> a -> a
lcm' a b = a`div`(gcd a b) * b
lcm :: Integral a => [a] -> a
lcm (n:ns) = foldr lcm' n ns

I even took the time to write my own gcd function, only to find it in Prelude! Lots of learning for me today :D

If you're putting a <meta> tag in your css files, you're doing something wrong. The <meta> tag belongs in your html files, and tells the browser how the html is encoded, it doesn't say anything about the css, which is a separate file. You could conceivably have completely different encodings for your html and css, although I can't imagine this would be a good idea.

The solution, if your list items can be display: inline is quite easy:

#footer { text-align: center; }
#footer ul { list-style: none; }
#footer ul li { display: inline; }

However, many times you must use display:block on your <li>s. The following CSS will work, in this case:

#footer { width: 100%; overflow: hidden; }
#footer ul { list-style: none; position: relative; float: left; display: block; left: 50%; }
#footer ul li { position: relative; float: left; display: block; right: 50%; }

in short, We can use rm -r -fo {folderName} to remove the folder recursively (remove all the files and folders inside) and force

You are looking for the window.scrollTop() function.

$(window).scroll(function() {
    var height = $(window).scrollTop();

    if(height  > some_number) {
        // do something
    }
});

hope that helps

I didn't want to install the x11-common and other components that come bundled in the apt-get install approach, so I just downloaded the .war file and ran the command Francois mentioned. That worked nicely, but you have to write your own daemon script with that approach. Full details here: http://strem.in/stream/9488/Using-the-war-file-for-jenkins-ci

Here is a plotrix solution:

set.seed(0815)
x <- 1:10
F <- runif(10,1,2) 
L <- runif(10,0,1)
U <- runif(10,2,3)

require(plotrix)
plotCI(x, F, ui=U, li=L)

And here is a ggplot solution:

set.seed(0815)
df <- data.frame(x =1:10,
                 F =runif(10,1,2),
                 L =runif(10,0,1),
                 U =runif(10,2,3))

require(ggplot2)
ggplot(df, aes(x = x, y = F)) +
  geom_point(size = 4) +
  geom_errorbar(aes(ymax = U, ymin = L))

UPDATE: Here is a base solution to your edits:

set.seed(1234)
x <- rnorm(20)
df <- data.frame(x = x,
                 y = x + rnorm(20))

plot(y ~ x, data = df)

# model
mod <- lm(y ~ x, data = df)

# predicts + interval
newx <- seq(min(df$x), max(df$x), length.out=100)
preds <- predict(mod, newdata = data.frame(x=newx), 
                 interval = 'confidence')

# plot
plot(y ~ x, data = df, type = 'n')
# add fill
polygon(c(rev(newx), newx), c(rev(preds[ ,3]), preds[ ,2]), col = 'grey80', border = NA)
# model
abline(mod)
# intervals
lines(newx, preds[ ,3], lty = 'dashed', col = 'red')
lines(newx, preds[ ,2], lty = 'dashed', col = 'red')

You can also pass to DataFrame.drop the label itself (instead of Series of index labels):

In[17]: df
Out[17]: 
            a         b         c         d         e
one  0.456558 -2.536432  0.216279 -1.305855 -0.121635
two -1.015127 -0.445133  1.867681  2.179392  0.518801

In[18]: df.drop('one')
Out[18]: 
            a         b         c         d         e
two -1.015127 -0.445133  1.867681  2.179392  0.518801

Which is equivalent to:

In[19]: df.drop(df.index[[0]])
Out[19]: 
            a         b         c         d         e
two -1.015127 -0.445133  1.867681  2.179392  0.518801

List.Exists (Object method - MSDN)

Determines whether the List(T) contains elements that match the conditions defined by the specified predicate.

This exists since .NET 2.0, so before LINQ. Meant to be used with the Predicate delegate, but lambda expressions are backward compatible. Also, just List has this (not even IList)

IEnumerable.Any (Extension method - MSDN)

Determines whether any element of a sequence satisfies a condition.

This is new in .NET 3.5 and uses Func(TSource, bool) as argument, so this was intended to be used with lambda expressions and LINQ.

In behaviour, these are identical.

If you spawn threads in Application_Start, they will still be executing in the application pool's AppDomain.

If an application is idle for some time (meaning that no requests are coming in), or certain other conditions are met, ASP.NET will recycle the entire AppDomain.

When that happens, any threads that you started from that AppDomain, including those from Application_Start, will be aborted.

Lots more on application pools and recycling in this question: What exactly is Appdomain recycling

If you are trying to run a long-running process within IIS/ASP.NET, the short answer is usually "Don't". That's what Windows Services are for.

As you can see, the response is still HTTP/1.1 200 OK. To indicate a redirect, you need to send back a 302 status code:

response.setStatus(HttpServletResponse.SC_FOUND); // SC_FOUND = 302

Here is what I did (for text). In the code, I copy whatever text is needed to clipboard. The first time an individual tries to use the share intent button, I pop up a notification that explains if they wish to share to facebook, they need to click 'Facebook' and then long press to paste (this is to make them aware that Facebook has BROKEN the android intent system). Then the relevant information is in the field. I might also include a link to this post so users can complain too...

private void setClipboardText(String text) { // TODO
    int sdk = android.os.Build.VERSION.SDK_INT;
    if(sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        clipboard.setText(text);
    } else {
        android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); 
        android.content.ClipData clip = android.content.ClipData.newPlainText("text label",text);
        clipboard.setPrimaryClip(clip);
    }
}

Below is a method for dealing w/prior versions

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.menu_item_share:
        Intent shareIntent = new Intent(Intent.ACTION_SEND);
        shareIntent.setType("text/plain");
        shareIntent.putExtra(Intent.EXTRA_TEXT, "text here");

        ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); //TODO
         ClipData clip = ClipData.newPlainText("label", "text here");
         clipboard.setPrimaryClip(clip);

        setShareIntent(shareIntent); 

        break;
    }
        return super.onOptionsItemSelected(item);
}

There's also a <=> operator:

SELECT pid FROM planets WHERE userid <=> NULL

Would work. The nice thing is that <=> can also be used with non-NULL values:

SELECT NULL <=> NULL yields 1.

SELECT 42 <=> 42 yields 1 as well.

See here: https://dev.mysql.com/doc/refman/5.7/en/comparison-operators.html#operator_equal-to

Use urllib2. For more specifics, check out this example from doc.python.org:

Here's a snippet from the tutorial that may help

import urllib2

req = urllib2.Request('ftp://example.com')
response = urllib2.urlopen(req)
the_page = response.read()

You need to check put method in Hash map first as HashSet is backed up by HashMap

1. When you add duplicate value say a String "One" into HashSet,
2. An entry ("one", PRESENT) will get inserted into Hashmap(for all the values added into set, the value will be "PRESENT" which if of type Object)
3. Hashmap adds the entry into Map and returns the value, which is in this case "PRESENT" or null if Entry is not there.
4. Hashset's add method then returns true if the returned value from Hashmap equals null otherwise false which means an entry already exists...

To add to the accepted answer:

Bear in mind that set -e sometimes is not enough, specially if you have pipes.

For example, suppose you have this script

#!/bin/bash
set -e 
./configure  > configure.log
make

... which works as expected: an error in configure aborts the execution.

Tomorrow you make a seemingly trivial change:

#!/bin/bash
set -e 
./configure  | tee configure.log
make

... and now it does not work. This is explained here, and a workaround (Bash only) is provided:

#!/bin/bash
set -e 
set -o pipefail

./configure  | tee configure.log
make

When we use CommandObj.Parameter.Add() it takes 2 parameters, the first is procedure parameter and the second is its data type, while .AddWithValue() takes 2 parameters, the first is procedure parameter and the second is the data variable

CommandObj.Parameter.Add("@ID",SqlDbType.Int).Value=textBox1.Text;

for .AddWithValue

CommandObj.Parameter.AddWitheValue("@ID",textBox1.Text);

where ID is the parameter of stored procedure which data type is Int

You can store the password in the configuration string by going to properties and adding password=yourpassword, but it's very important to put a space after the ; on the line before password and after the ; on the password line, as shown below:

Data Source=50.21.65.225;User ID=vc_ssis; 
password=D@mc317Feo; 
Initial Catalog=Sales;
Provider=SQLNCLI10.1;
Persist Security Info=True;Auto Translate=False;
Application Name=SSIS-PKG_CustomerData-{2A666833-6095-4486-C04F-350CBCA5C49E}IDM11.Sales.dev;

In Java threads are not killed, but the stopping of a thread is done in a cooperative way. The thread is asked to terminate and the thread can then shutdown gracefully.

Often a volatile boolean field is used which the thread periodically checks and terminates when it is set to the corresponding value.

I would not use a boolean to check whether the thread should terminate. If you use volatile as a field modifier, this will work reliable, but if your code becomes more complex, for instead uses other blocking methods inside the while loop, it might happen, that your code will not terminate at all or at least takes longer as you might want.

Certain blocking library methods support interruption.

Every thread has already a boolean flag interrupted status and you should make use of it. It can be implemented like this:

public void run() {
   try {
      while (!interrupted()) {
         // ...
      }
   } catch (InterruptedException consumed)
      /* Allow thread to exit */
   }
}

public void cancel() { interrupt(); }

Source code adapted from Java Concurrency in Practice. Since the cancel() method is public you can let another thread invoke this method as you wanted.

Please try http://www.osjava.org/jardiff/ - tool is old and the dependency list is large. From the docs, it looks like worth trying.

Answer is you can't explicitly but you should be freeing memory in your routines.

Some tips though to help memory

• Make sure you set object to null before exiting your routine.
• Ensure you call Close on objects if they require it.
• Don't use global variables unless absolutely necessary

I would recommend checking the memory usage after performing the routine again and again you may have a memory leak.

This is what working for me

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</android.support.v4.widget.NestedScrollView>

variable=$(ps -ef | awk '/[p]ort 10/ {print $12}')

The [p] is a neat trick to remove the search from showing from ps

@Jeremy If you post the output of ps -ef | grep "port 10", and what you need from the line, it would be more easy to help you getting correct syntax

You could use

os.path.abspath(path_with_backlash)

it returns the path with \

updated() should be what you're looking for:

Called after a data change causes the virtual DOM to be re-rendered and patched.

The component’s DOM will have been updated when this hook is called, so you can perform DOM-dependent operations here.

Another option would be:

$scope.parseInt = parseInt;

Then you could do this like you wanted:

{{parseInt(num_str)-1}}

This is because angular expressions don't have access to the window, only to scope.

Also, with the number filter, wrapping your expression in parentheses works:

{{(num_str-1) | number}}

DEMO

There are a couple of ways to address your problem, however this is probably the most straightforward:

Your main method is static, so it does not have access to instance members (isLeapYear field and isLeapYear method. One approach to rectify this is to make both the field and the method static as well:

static boolean isLeapYear;
/* (snip) */
public static boolean isLeapYear(int year)
{
  /* (snip) */
}

Lastly, you're not actually calling your isLeapYear method (which is why you're not seeing any results). Add this line after int year = kboard.nextInt();:

isLeapYear(year);

That should be a start. There are some other best practices you could follow but for now just focus on getting your code to work; you can refactor later.

You can't close an alert box with Javascript.

You could, however, use a window instead:

var w = window.open('','','width=100,height=100')
w.document.write('Message')
w.focus()
setTimeout(function() {w.close();}, 5000)

You can use numpy's slicing, simply start:stop:step.

>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])

This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2]         # O(1), constant time
>>> b[:] = 0           # modifying the view changes original array
>>> a                  # original array is modified
array([0, 2, 0, 4, 0])

so if either of the above things are a problem, you can make a copy explicitly:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy()  # explicit copy, O(n)
>>> b[:] = 0           # modifying the copy
>>> a                  # original is intact
array([1, 2, 3, 4, 5])

This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.

I normally use the 'back tick' feature of bash

export NUM_LINES=`wc -l filename`

Note the 'tick' is the 'back tick' e.g. ` not the normal single quote

The accepted answer is invalid with the double EXEC (only need the first EXEC):

DECLARE @returnvalue int;
EXEC @returnvalue = SP_SomeProc
PRINT @returnvalue

And you still need to call PRINT (at least in Visual Studio).

The reference you have listed for Ruby is for Ruby on Rails. While still ruby deep down, it is definitely not a place to start for people wanting to learn Ruby.

For Ruby tutorials, I would suggest Why's (Poignant) Guide to Ruby as a great starting point for anyone interested in the language.

If you would want to get into more detail, I would recommend the book Programming Ruby, which has become the standard for all things Ruby. The third edition is currently being written, highlighting Ruby 1.9 features, so I would hold off for a while if anyone is considering buying this book.

I wouldn't use:

svn checkout

just to authorizes the server authentication, I rather use:

svn list https://your.repository.url

which will ask you to do the authentication as well.

If this is needed to get authorization to a user that can't login, run:

sudo -u username svn list https://your.repository.url

Put in the URL bar and then click enter:

You can select and copy the text from the alert depending on the website and the web browser you are using.

It Doesn't work in Laravel 5.3+ if you want to try to access the value from the controller like below. It always returns null

<?php

    $value = env('MY_VALUE', 'default_value');

SOLUTION: Rather, you need to create a file in the configuration folder, say values.php and then write the code like below

File values.php

<?php

    return [

        'myvalue' => env('MY_VALUE',null),

        // Add other values as you wish

Then access the value in your controller with the following code

<?php

    $value = \Config::get('values.myvalue')

Where "values" is the filename followed by the key "myvalue".

Here is a small example how to add a matplotlib grid in Gtk3 with Python 2 (not working in Python 3):

#!/usr/bin/env python
#-*- coding: utf-8 -*-

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
from matplotlib.figure import Figure
from matplotlib.backends.backend_gtk3agg import FigureCanvasGTK3Agg as FigureCanvas

win = Gtk.Window()
win.connect("delete-event", Gtk.main_quit)
win.set_title("Embedding in GTK3")

f = Figure(figsize=(1, 1), dpi=100)
ax = f.add_subplot(111)
ax.grid()

canvas = FigureCanvas(f)
canvas.set_size_request(400, 400)
win.add(canvas)

win.show_all()
Gtk.main()

this seems to be an ASPX pages problem, I have never been able to show a favicon in any page for IE (all others yes Chrome, FF and safari) the only sites that I've seen that are the exception to that rule are bing.com, msdn.com and others that belong to MS and run on asp.net, there is something that they are not telling us! even world-known sites cant show in IE eg: manu.com (most browsed sports team in the world) aspx site and fails to dislplay the favicon on IE. http://www.manutd.com/favicon.ico does show the icon.

Please prove me wrong.

DateTime.Now.ToString("dd/MM/yyyy");

In my case I had multiple elements to hide on document.ready. This is the function (filter) that worked for me so far:

$('[name="_invisibleIfEmpty"]').filter(function () {
    return $.trim($(this).html()).length == 0;
}).hide();

or .remove() rather than .hide(), whatever you prefer.

FYI: This, in particular, is the solution I am using to hide annoying empty table cells in SharePoint (in addition with this condition "|| $(this).children("menu").length".

There are basically 4 techniques for this task, all of them standard SQL.

NOT EXISTS

Often fastest in Postgres.

SELECT ip 
FROM   login_log l 
WHERE  NOT EXISTS (
   SELECT  -- SELECT list mostly irrelevant; can just be empty in Postgres
   FROM   ip_location
   WHERE  ip = l.ip
   );

Also consider:

• What is easier to read in EXISTS subqueries?

LEFT JOIN / IS NULL

Sometimes this is fastest. Often shortest. Often results in the same query plan as NOT EXISTS.

SELECT l.ip 
FROM   login_log l 
LEFT   JOIN ip_location i USING (ip)  -- short for: ON i.ip = l.ip
WHERE  i.ip IS NULL;

EXCEPT

Short. Not as easily integrated in more complex queries.

SELECT ip 
FROM   login_log

EXCEPT ALL  -- "ALL" keeps duplicates and makes it faster
SELECT ip
FROM   ip_location;

Note that (per documentation):

duplicates are eliminated unless EXCEPT ALL is used.

Typically, you'll want the ALL keyword. If you don't care, still use it because it makes the query faster.

NOT IN

Only good without NULL values or if you know to handle NULL properly. I would not use it for this purpose. Also, performance can deteriorate with bigger tables.

SELECT ip 
FROM   login_log
WHERE  ip NOT IN (
   SELECT DISTINCT ip  -- DISTINCT is optional
   FROM   ip_location
   );

NOT IN carries a "trap" for NULL values on either side:

• Find records where join doesn't exist

Similar question on dba.SE targeted at MySQL:

• Select rows where value of second column is not present in first column

You need to use overflow option like below:

.nav{
    max-height: 300px;
    overflow-y: scroll; 
}

Change the height according to amount of items you need to show

use Below command in terminal

php artisan cache:clear
php artisan route:cache 
php artisan config:cache 
php artisan view:clear

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

It is written here that "By default, Android Studio 2.2 and the Android Plugin for Gradle 2.2 sign your app using both APK Signature Scheme v2 and the traditional signing scheme, which uses JAR signing."

As it seems that these new checkboxes appeared with Android 2.3, I understand that my previous versions of Android Studio (at least the 2.2) did sign with both signatures. So, to continue as I did before, I think that it is better to check both checkboxes.

EDIT March 31st, 2017 : submitted several apps with both signatures => no problem :)

The easiest way to get the finger print is to switch from app to signed report by clicking the drop down and click build.

Then you will be able to see the sha1 fingerprint at the bottom pane where you see the debug report and stack trace. N.B remember to switch back to app when you want to run your app on a device or an emulator.

../images/logo.png will move you back one folder.

../../images/logo.png will move you back two folders.

/images/logo.png will take you back to the root folder no matter where you are/.

This can also be if the application does not support the TLS version the SMTP host is using.

For example, trying to configure an SMTP server that uses TLSv1.2 without fallback, when your application(or java program using an older javax.mail JAR) supports only upto TLSv1.1.

I found another way in addition to command+option+shift+K. In XCode 4.2 there is an organizer that can be opened from top-right icon. You can clean all archives and saved project options from there. This helped my situation (I was seeing old removed files in the mainBundle).

I'm using the following, though it's hardcoded for gnome-terminal. It also changes the CWD and buffer for vim to be the same as your current buffer and it's directory.

:silent execute '!gnome-terminal -- zsh -i -c "cd ' shellescape(expand("%:h")) '; vim' shellescape(expand("%:p")) '; zsh -i"' <cr>

The answer to this other question shows you how to do that: Javascript equivalent of Python's locals()?

Basically, you can say

window["foo"](arg1, arg2);

or as many others have suggested, you can just use eval:

eval(fname)(arg1, arg2);

although this is extremely unsafe unless you're absolutely sure about what you're eval-ing.

After trying different things, it turns out it was VS cache. You can resolve it by deleting the cache files located in:

C:\Users\your.name.here\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

I closed my project, deleted the files on that path and reopened my project, cleaned the solution and built it again and the problem was solved

The files will be recreated when you next launch Visual Studio

use trim() method of javascript after all angularjs is also a javascript framework and it is not necessary to put $ to apply trim()

for example

var x="hello world";
x=x.trim()

If you set a variable via SETX, you cannot use this variable or its changes immediately. You have to restart the processes that want to use it.

Use the following sequence to directly set it in the setting process too (works for me perfectly in scripts that do some init stuff after setting global variables):

SET XYZ=test
SETX XYZ test

'So from this discussion i am thinking this should be the code then.

Sub Button1_Click()

'Let me know if this is correct or a step was missed. Thx.

You can do like this :

webelement time=driver.findElement(By.id("input_name")).getAttribute("value");

this will give you the time displaying on the webpage.

From a posting by Matz:

(1) ++ and -- are NOT reserved operator in Ruby.

(2) C's increment/decrement operators are in fact hidden assignment. They affect variables, not objects. You cannot accomplish assignment via method. Ruby uses +=/-= operator instead.

(3) self cannot be a target of assignment. In addition, altering the value of integer 1 might cause severe confusion throughout the program.

                      matz.

Check your error log file and then use the tail command as:

tail -200f /var/log/redis_6379.log

or

 tail -200f /var/log/redis.log

According to your error file name..

You're going to have to rely on each individual's machine having the correct file associations. If you try and open the application from JavaScript/VBScript in a web page, the spawned application is either going to itself be sandboxed (meaning decreased permissions) or there are going to be lots of security prompts.

My suggestion is to look to SharePoint server for this one. This is something that we know they do and you can edit in place, but the question becomes how they manage to pull that off. My guess is direct integration with Office. Either way, this isn't something that the Internet is designed to do, because I'm assuming you want them to edit the original document and not simply create their own copy (which is what the default behavior of file:// would be.

So depending on you options, it might be possible to create a client side application that gets installed on all your client machines and then responds to a particular file handler that says go open this application on the file server. Then it wouldn't really matter who was doing it since all browsers would simply hand off the request to you. You would have to create your own handler like fileserver://.

Just do that: getTabAt(index of your tab)

        ActionBar actionBar = getSupportActionBar();
        actionBar.selectTab(actionBar.getTabAt(0));

This is the better solution:

verify(mock_contractsDao, times(1)).save(Mockito.eq("Parameter I'm expecting"));
