Use --build-arg with each argument.

If you are passing two argument then add --build-arg with each argument like:

docker build \
-t essearch/ess-elasticsearch:1.7.6 \
--build-arg number_of_shards=5 \
--build-arg number_of_replicas=2 \
--no-cache .

My own experience has been that it's best to stick to one of two kinds of assembly references:

• A 'local' assembly in the current build directory
• An assembly in the GAC

I've found (much like you've described) other methods to either be too easily broken or have annoying maintenance requirements.

Any assembly I don't want to GAC, has to live in the execution directory. Any assembly that isn't or can't be in the execution directory I GAC (managed by automatic build events).

This hasn't given me any problems so far. While I'm sure there's a situation where it won't work, the usual answer to any problem has been "oh, just GAC it!". 8 D

Hope that helps!

Although I take the risk of not being popular I say they are not useful nowadays.

I think they were well intended and useful in the past when for example DELETE told the server to delete the resource found at supplied URL and PUT (with its sibling PATCH) told the server to do update in an idempotent manner.

Things evolved and URLs became virtual (see url rewriting for example) making resources lose their initial meaning of real folder/subforder/file and so, CRUD action verbs covered by HTTP protocol methods (GET, POST, PUT/PATCH, DELETE) lost track.

Let's take an example:

• /api/entity/list/{id} vs GET /api/entity/{id}
• /api/entity/add/{id} vs POST /api/entity
• /api/entity/edit/{id} vs PUT /api/entity/{id}
• /api/entity/delete/{id} vs DELETE /api/entity/{id}

On the left side is not written the HTTP method, essentially it doesn't matter (POST and GET are enough) and on the right side appropriate HTTP methods are used.

Right side looks elegant, clean and professional. Imagine now you have to maintain a code that's been using the elegant API and you have to search where deletion call is done. You'll search for "api/entity" and among results you'll have to see which one is doing DELETE. Or even worse, you have a junior programmer which by mistake switched PUT with DELETE and as URL is the same shit happened.

In my opinion putting the action verb in the URL has advantages over using the appropriate HTTP method for that action even if it's not so elegant. If you want to see where delete call is made you just have to search for "api/entity/delete" and you'll find it straight away.

Building an API without the whole HTTP array of methods makes it easier to be consumed and maintained afterwards

I insert this code in my tag and it works correctly:

You got a bunch of good answers, so I'll just throw out a suggestion. If you are going to be working on this project for more than 2 days, download eclipse or netbeans and build your project in there.

If you are not normally a java programmer, then the help it will give you will be invaluable.

It's not worth the 1/2 hour download/install if you are only spending 2 hours on it.

Both have hotkeys/menu items to "Fix imports", with this you should never have to worry about imports again.

If you want the error class, error message, and stack trace, use sys.exc_info().

Minimal working code with some formatting:

import sys
import traceback

try:
    ans = 1/0
except BaseException as ex:
    # Get current system exception
    ex_type, ex_value, ex_traceback = sys.exc_info()

    # Extract unformatter stack traces as tuples
    trace_back = traceback.extract_tb(ex_traceback)

    # Format stacktrace
    stack_trace = list()

    for trace in trace_back:
        stack_trace.append("File : %s , Line : %d, Func.Name : %s, Message : %s" % (trace[0], trace[1], trace[2], trace[3]))

    print("Exception type : %s " % ex_type.__name__)
    print("Exception message : %s" %ex_value)
    print("Stack trace : %s" %stack_trace)

Which gives the following output:

Exception type : ZeroDivisionError
Exception message : division by zero
Stack trace : ['File : .\\test.py , Line : 5, Func.Name : <module>, Message : ans = 1/0']

The function sys.exc_info() gives you details about the most recent exception. It returns a tuple of (type, value, traceback).

traceback is an instance of traceback object. You can format the trace with the methods provided. More can be found in the traceback documentation .

I think this is what you were looking for:

grep -E "string1|string2" filename

I think that answers like this:

grep 'string1.*string2\|string2.*string1' filename

only match the case where both are present, not one or the other or both.

strftime("%Y");

I love strftime. It's a great function for grabbing/recombining chunks of dates/times.

Plus it respects locale settings which the date function doesn't do.

Take a look at this site, it explains two methods for reading from console in java, using Scanner or the classical InputStreamReader from System.in.

Following code is taken from cited website:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ReadConsoleSystem {
  public static void main(String[] args) {

    System.out.println("Enter something here : ");

    try{
        BufferedReader bufferRead = new BufferedReader(new InputStreamReader(System.in));
        String s = bufferRead.readLine();

        System.out.println(s);
    }
    catch(IOException e)
    {
        e.printStackTrace();
    }

  }
}

--

import java.util.Scanner;

public class ReadConsoleScanner {
  public static void main(String[] args) {

      System.out.println("Enter something here : ");

       String sWhatever;

       Scanner scanIn = new Scanner(System.in);
       sWhatever = scanIn.nextLine();

       scanIn.close();            
       System.out.println(sWhatever);
  }
}

Conceptually speaking, keeping the language specific implementation, rules, benefits and achieving any programming goal by using anyone or both, can or cant have code/data/property, blah blah, single or multiple inheritances, all aside

1- Abstract (or pure abstract) Class is meant to implement hierarchy. If your business objects look somewhat structurally similar, representing a parent-child (hierarchy) kind of relationship only then inheritance/Abstract classes will be used. If your business model does not have a hierarchy then inheritance should not be used (here I am not talking about programming logic e.g. some design patterns require inheritance). Conceptually, abstract class is a method to implement hierarchy of a business model in OOP, it has nothing to do with Interfaces, actually comparing Abstract class with Interface is meaningless because both are conceptually totally different things, it is asked in interviews just to check the concepts because it looks both provide somewhat same functionality when implementation is concerned and we programmers usually emphasize more on coding. [Keep this in mind as well that Abstraction is different than Abstract Class].

2- an Interface is a contract, a complete business functionality represented by one or more set of functions. That is why it is implemented and not inherited. A business object (part of a hierarchy or not) can have any number of complete business functionality. It has nothing to do with abstract classes means inheritance in general. For example, a human can RUN, an elephant can RUN, a bird can RUN, and so on, all these objects of different hierarchy would implement the RUN interface or EAT or SPEAK interface. Don't go into implementation as you might implement it as having abstract classes for each type implementing these interfaces. An object of any hierarchy can have a functionality(interface) which has nothing to do with its hierarchy.

I believe, Interfaces were not invented to achieve multiple inheritances or to expose public behavior, and similarly, pure abstract classes are not to overrule interfaces but Interface is a functionality that an object can do (via functions of that interface) and Abstract Class represents a parent of a hierarchy to produce children having core structure (property+functionality) of the parent

When you are asked about the difference, it is actually conceptual difference not the difference in language-specific implementation unless asked explicitly.

I believe, both interviewers were expecting one line straightforward difference between these two and when you failed they tried to drove you towards this difference by implementing ONE as the OTHER

What if you had an Abstract class with only abstract methods?

Here is a python solution using the pip install PyGithub package

from github import Github
g = Github("youroauth key") #create token from settings page


for repo in g.get_user().get_repos():
    if repo.name == "yourreponame":
        releases = repo.get_releases()
        for i in releases:
            if i.tag_name == "yourtagname":
                for j in i.get_assets():
                    print("{} date: {} download count: {}".format(j.name, j.updated_at, j._download_count.value))

Mssql stored procedure vs function:

The command is lowercase: touch filename.

Keep in mind that touch will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch

If you always want an empty file, one way to do so would be to use:

echo "" > filename

Like so?

static void Main()
{
    byte[] data = FromHex("47-61-74-65-77-61-79-53-65-72-76-65-72");
    string s = Encoding.ASCII.GetString(data); // GatewayServer
}
public static byte[] FromHex(string hex)
{
    hex = hex.Replace("-", "");
    byte[] raw = new byte[hex.Length / 2];
    for (int i = 0; i < raw.Length; i++)
    {
        raw[i] = Convert.ToByte(hex.Substring(i * 2, 2), 16);
    }
    return raw;
}

I think you may be confusing Javascript with jQuery methods. Vanilla or plain Javascript is something like:

function example() {
}

A function of that nature can be called at any time, anywhere.

jQuery (a library built on Javascript) has built in functions that generally required the DOM to be fully rendered before being called. The syntax for when this is completed is:

$(document).ready(function() {
});

So a jQuery function, which is prefixed with the $ or the word jQuery generally is called from within that method.

$(document).ready(function() {        
    // Assign all list items on the page to be the  color red.  
    //      This does not work until AFTER the entire DOM is "ready", hence the $(document).ready()
    $('li').css('color', 'red');   
});

The pseudo-code for that block is:

When the document object model $(document) is ready .ready(), call the following function function() { }. In that function, check for all <li>'s on the page $('li') and using the jQuery method .CSS() to set the CSS property "color" to the value "red" .css('color', 'red');

I think there is little difference between the two events. To understand this, I created a simple example to manipulation:

XAML

<Window x:Class="LoadedAndContentRendered.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Name="MyWindow"
        Title="MainWindow" Height="1000" Width="525"
        WindowStartupLocation="CenterScreen"
        ContentRendered="Window_ContentRendered"     
        Loaded="Window_Loaded">

    <Grid Name="RootGrid">        
    </Grid>
</Window>

Code behind

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered");
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded");
}   

In this case the message Loaded appears the first after the message ContentRendered. This confirms the information in the documentation.

In general, in WPF the Loaded event fires if the element:

is laid out, rendered, and ready for interaction.

Since in WPF the Window is the same element, but it should be generally content that is arranged in a root panel (for example: Grid). Therefore, to monitor the content of the Window and created an ContentRendered event. Remarks from MSDN:

If the window has no content, this event is not raised.

That is, if we create a Window:

<Window x:Class="LoadedAndContentRendered.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Name="MyWindow"        
    ContentRendered="Window_ContentRendered" 
    Loaded="Window_Loaded" />

It will only works Loaded event.

With regard to access to the elements in the Window, they work the same way. Let's create a Label in the main Grid of Window. In both cases we have successfully received access to Width:

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered: " + SampleLabel.Width.ToString());
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded: " + SampleLabel.Width.ToString());
}   

As for the Styles and Templates, at this stage they are successfully applied, and in these events we will be able to access them.

For example, we want to add a Button:

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered: " + SampleLabel.Width.ToString());

    Button b1 = new Button();
    b1.Content = "ContentRendered Button";
    RootGrid.Children.Add(b1);
    b1.Height = 25;
    b1.Width = 200;
    b1.HorizontalAlignment = HorizontalAlignment.Right;
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded: " + SampleLabel.Width.ToString());

    Button b1 = new Button();
    b1.Content = "Loaded Button";
    RootGrid.Children.Add(b1);
    b1.Height = 25;
    b1.Width = 200;
    b1.HorizontalAlignment = HorizontalAlignment.Left;
}

In the case of Loaded event, Button to add to Grid immediately at the appearance of the Window. In the case of ContentRendered event, Button to add to Grid after all its content will appear.

Therefore, if you want to add items or changes before load Window you must use the Loaded event. If you want to do the operations associated with the content of Window such as taking screenshots you will need to use an event ContentRendered.

Using query comprehension syntax you could achieve the orderby as follows:

var uniqueColors = (from dbo in database.MainTable
                    where dbo.Property
                    orderby dbo.Color.Name ascending
                    select dbo.Color.Name).Distinct();

Quick comparison of timings in response to the post by Abbafei:

import timeit

def func1():
    phrase = 'Lucky Dog'
    return any(i in 'LD' for i in phrase)

def func2():
    phrase = 'Lucky Dog'
    if ('L' in phrase) or ('D' in phrase):
        return True
    else:
        return False

if __name__ == '__main__': 
    func1_time = timeit.timeit(func1, number=100000)
    func2_time = timeit.timeit(func2, number=100000)
    print('Func1 Time: {0}\nFunc2 Time: {1}'.format(func1_time, func2_time))

Output:

Func1 Time: 0.0737484362111
Func2 Time: 0.0125144964371

So the code is more compact with any, but faster with the conditional.

EDIT : TL;DR -- For long strings, if-then is still much faster than any!

I decided to compare the timing for a long random string based on some of the valid points raised in the comments:

# Tested in Python 2.7.14

import timeit
from string import ascii_letters
from random import choice

def create_random_string(length=1000):
    random_list = [choice(ascii_letters) for x in range(length)]
    return ''.join(random_list)

def function_using_any(phrase):
    return any(i in 'LD' for i in phrase)

def function_using_if_then(phrase):
    if ('L' in phrase) or ('D' in phrase):
        return True
    else:
        return False

if __name__ == '__main__':
    random_string = create_random_string(length=2000)
    func1_time = timeit.timeit(stmt="function_using_any(random_string)",
                               setup="from __main__ import function_using_any, random_string",
                               number=200000)
    func2_time = timeit.timeit(stmt="function_using_if_then(random_string)",
                               setup="from __main__ import function_using_if_then, random_string",
                               number=200000)
    print('Time for function using any: {0}\nTime for function using if-then: {1}'.format(func1_time, func2_time))

Output:

Time for function using any: 0.1342546
Time for function using if-then: 0.0201827

If-then is almost an order of magnitude faster than any!

If you wanted to search some elements based on a regex, you can use the filter function. For example, say you wanted to make sure that in all the input boxes, the user has only entered numbers, so let's find all the inputs which don't match and highlight them.

$("input:text")
    .filter(function() {
        return this.value.match(/[^\d]/);
    })
    .addClass("inputError")
;

Of course if it was just something like this, you could use the form validation plugin, but this method could be applied to any sort of elements you like. Another example to show what I mean: Find all the elements whose id matches /[a-z]+_\d+/

$("[id]").filter(function() {
    return this.id.match(/[a-z]+_\d+/);
});

How about that?

function internalHandler(e) {
    e.preventDefault(); // required in some browsers
    e.returnValue = ""; // required in some browsers
    return "Custom message to show to the user"; // only works in old browsers
}

if (window.addEventListener) {
    window.addEventListener('beforeunload', internalHandler, true);
} else if (window.attachEvent) {
    window.attachEvent('onbeforeunload', internalHandler);
}

To resolve your problem, write the following line on your page's Page_Load method.

if (String.IsNullOrEmpty(Request.QueryString["aspxerrorpath"])) return;

.Net 4.0 provides more closer look to null, empty or whitespace strings, use it as shown in the following line:

if(string.IsNullOrWhiteSpace(Request.QueryString["aspxerrorpath"])) return;

This will not run your next statements (your business logics) if query string does not have aspxerrorpath.

Type 1: If statement style

{props.hasImage &&

  <MyImage />

}

Type 2: If else statement style

   {props.hasImage ?

      <MyImage /> :

      <OtherElement/>

    }

Okay: This is what I did now and it's solved:

My httpd-vhosts.conf looks like this now:

<VirtualHost dropbox.local:80>
    DocumentRoot "E:/Documenten/Dropbox/Dropbox/dummy-htdocs"
    ServerName dropbox.local
    ErrorLog "logs/dropbox.local-error.log"
    CustomLog "logs/dropbox.local-access.log" combined
    <Directory "E:/Documenten/Dropbox/Dropbox/dummy-htdocs">
        # AllowOverride All      # Deprecated
        # Order Allow,Deny       # Deprecated
        # Allow from all         # Deprecated

        # --New way of doing it
        Require all granted    
    </Directory>
</VirtualHost>

First, I saw that it's necessary to have set the <Directory xx:xx> options. So I put the <Directory > [..] </Directory>-part INSIDE the <VirtualHost > [..] </VirtualHost>. After that, I added AllowOverride AuthConfig Indexes to the <Directory> options.

Now http://localhost also points to the dropbox-virtualhost. So I added dropbox.local to <VirtualHost *:80> which makes it as <VirtualHost dropbox.local:80>

FINALLY it works :D!

I'm a happy man! :) :)

I hope someone else can use this information.

Oops, immediately found 2//2.

When you want it to validate (in XML/XHTML - thanks, Loren Segal).

You can use unfocus() method from FocusNode class.

import 'package:flutter/material.dart';

class MyHomePage extends StatefulWidget {
  MyHomePageState createState() => new MyHomePageState();
}

class MyHomePageState extends State<MyHomePage> {
  TextEditingController _controller = new TextEditingController();
  FocusNode _focusNode = new FocusNode(); //1 - declare and initialize variable

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(),
      floatingActionButton: new FloatingActionButton(
        child: new Icon(Icons.send),
        onPressed: () {
            _focusNode.unfocus(); //3 - call this method here
        },
      ),
      body: new Container(
        alignment: FractionalOffset.center,
        padding: new EdgeInsets.all(20.0),
        child: new TextFormField(
          controller: _controller,
          focusNode: _focusNode, //2 - assign it to your TextFormField
          decoration: new InputDecoration(labelText: 'Example Text'),
        ),
      ),
    );
  }
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new MyHomePage(),
    );
  }
}

void main() {
  runApp(new MyApp());
}

Note that since early December 2012, you can create new files directly from GitHub:

ProTip™: You can pre-fill the filename field using just the URL.
Typing ?filename=yournewfile.txt at the end of the URL will pre-fill the filename field with the name yournewfile.txt.

As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

The better use of 'while: else:' construction in Python should be if no loop is executed in 'while' then the 'else' statement is executed. The way it works today doesn't make sense because you can use the code below with the same results...

n = 5
while n != 0:
    print n
    n -= 1
print "what the..."

The logic will be:

SELECT * FROM objects WHERE Date LIKE '$_POST[period]-%';

The LIKE operator will select all rows that start with $_POST['period'] followed by dash and the day of the mont

set title color

btnGere.setTitleColor(#colorLiteral(red: 0, green: 0, blue: 0, alpha: 1), for: .normal)

I've decided to give an answer to this question because I think it can be solved using a simpler syntax than the convoluted try-catch block. The Laravel documentation is pretty brief on this subject.

Instead of using try-catch, you can just use the DB::transaction(){...} wrapper like this:

// MyController.php
public function store(Request $request) {
    return DB::transaction(function() use ($request) {
        $user = User::create([
            'username' => $request->post('username')
        ]);

        // Add some sort of "log" record for the sake of transaction:
        $log = Log::create([
            'message' => 'User Foobar created'
        ]);

        // Lets add some custom validation that will prohibit the transaction:
        if($user->id > 1) {
            throw AnyException('Please rollback this transaction');
        }

        return response()->json(['message' => 'User saved!']);
    });
};

You should then see that the User and the Log record cannot exist without eachother.

Some notes on the implementation above:

• Make sure to return the transaction, so that you can use the response() you return within its callback.
• Make sure to throw an exception if you want the transaction to be rollbacked (or have a nested function that throws the exception for you automatically, like an SQL exception from within Eloquent).
• The id, updated_at, created_at and any other fields are AVAILABLE AFTER CREATION for the $user object (for the duration of this transaction). The transaction will run through any of the creation logic you have. HOWEVER, the whole record is discarded when the AnyException is thrown. This means that for instance an auto-increment column for id does get incremented on failed transactions.

Tested on Laravel 5.8

I come across this problem when I tried to convert to Australian date format in excel. I split the cell with delimiter and used the following code from split cells then altered the issue areas.

=date(dd,mm,yy)

Yes, if your Column annotation has the runtime retention

@Retention(RetentionPolicy.RUNTIME)
@interface Column {
    ....
}

you can do something like this

for (Field f: MyClass.class.getFields()) {
   Column column = f.getAnnotation(Column.class);
   if (column != null)
       System.out.println(column.columnName());
}

UPDATE : To get private fields use

Myclass.class.getDeclaredFields()

The answer did not work for me. I dont know how it got so many votes. Though it helped in pointing me in a direction.

This is the answer that worked for me:

foreach (var x in jobj)
{
    var key = ((JProperty) (x)).Name;
    var jvalue = ((JProperty)(x)).Value ;
}

I'm using Visual Studio too much and I want to see params when I click on Ctrl+Space that's why I'm using Visual Studio keys. To change keymap to VS keymap:

I believe if you're willing to apply the approach to every possible orientation and to negative versions, a good start to image recognition (with good reliability) is to use eigenfaces: http://en.wikipedia.org/wiki/Eigenface

Another idea would be to transform both images into vectors of their components. A good way to do this is to create a vector that operates in x*y dimensions (x being the width of your image and y being the height), with the value for each dimension applying to the (x,y) pixel value. Then run a variant of K-Nearest Neighbours with two categories: match and no match. If it's sufficiently close to the original image it will fit in the match category, if not then it won't.

K Nearest Neighbours(KNN) can be found here, there are other good explanations of it on the web too: http://en.wikipedia.org/wiki/K-nearest_neighbor_algorithm

The benefits of KNN is that the more variants you're comparing to the original image, the more accurate the algorithm becomes. The downside is you need a catalogue of images to train the system first.

All the test for my class became inconclusive after some code changes (they were passing previously).

It appeared that I had added a new field to my testing class:

private readonly Foo _foo = CreateFoo();

The problem was that an exception was thrown inside 'CreateFoo()', so it happened for all the tests and instead of failing they all became inconclusive.

I was having an error The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[16.0.2,16.0.2]], but resolves to 16.0.0. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

Running ./gradlew :app:dependencies will reveal what dependencies are requiring wrong dependencies (the ones in the square bracket). For me the problem was coming from firebase-core:16.0.3 as shown below. I fixed it by downgrading firebase-core to 16.0.1

As a generic extension, 2.0-compatible:

using System.Collections.Generic;
public static class Extensions {
    //=========================================================================
    // Removes all instances of [itemToRemove] from array [original]
    // Returns the new array, without modifying [original] directly
    // .Net2.0-compatible
    public static T[] RemoveFromArray<T> (this T[] original, T itemToRemove) {  
        int numIdx = System.Array.IndexOf(original, itemToRemove);
        if (numIdx == -1) return original;
        List<T> tmp = new List<T>(original);
        tmp.RemoveAt(numIdx);
        return tmp.ToArray();
    }
}

Usage:

int[] numbers = {1, 3, 4, 9, 2};
numbers = numbers.RemoveFromArray(4);

v.Dt is likely not a Date() object.

See http://jsfiddle.net/southerd/xG2t8/

but in your controller:

scope.v.Dt = Date.parse(scope.v.Dt);

This would work

setInterval(function(){$("#myButtonId").click();}, 1000);

Alternatively, you can use XPath query via XPathSelectElements method:

var document = XDocument.Parse(yourXmlAsString);
var words = document.XPathSelectElements("//word[./category[text() = 'verb']]");

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

* Update *

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29

Another javascript library worth mentioning is pdfmake.

• pdfmake playground
• pdfmake on github

The browser support does not appear to be as strong as jsPDF, nor does there seem to be an option for shapes, but the options for formatting text are more advanced then the options currently available in jsPDF.

If you want to disable unreferenced local variable write in some header

template<class T>
void ignore (const T & ) {}

and use

catch(const Except & excpt) {
    ignore(excpt); // No warning
    // ...  
} 

As there is no language tag with this post, I'm gonna give a regex solution used within python.

The expression itself:

1[\s./-]?\(?[\d]+\)?[\s./-]?[\d]+[-/.]?[\d]+\s?[\d]+

When used within python:

import re

phonelist ="1-234-567-8901,1-234-567-8901 1234,1-234-567-8901 1234,1 (234) 567-8901,1.234.567.8901,1/234/567/8901,12345678901"

phonenumber = '\n'.join([phone for phone in re.findall(r'1[\s./-]?\(?[\d]+\)?[\s./-]?[\d]+[-/.]?[\d]+\s?[\d]+' ,phonelist)])
print(phonenumber)

Output:

1-234-567-8901
1-234-567-8901 1234
1-234-567-8901 1234
1 (234) 567-8901
1.234.567.8901
1/234/567/8901
12345678901

Your code is absolutely fine. It just needs "exit 0" for a cleaner exit.

 tncserver.exe C:\Work -p4 -b57600 -r -cFE -tTNC426B
 exit 0

The fix for me was to set property HorizontalAlignment="Stretch" on ItemsPresenter inside ScrollViewer..

Hope this helps someone...

<Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListBox">
                    <ScrollViewer x:Name="ScrollViewer" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Foreground="{TemplateBinding Foreground}" Padding="{TemplateBinding Padding}" HorizontalAlignment="Stretch">
                        <ItemsPresenter  Height="252" HorizontalAlignment="Stretch"/>
                    </ScrollViewer>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

Try this code: In testing.html

function testJS() {
    var b = document.getElementById('name').value,
        url = 'http://path_to_your_html_files/next.html?name=' + encodeURIComponent(b);

    document.location.href = url;
}

And in next.html:

window.onload = function () {
    var url = document.location.href,
        params = url.split('?')[1].split('&'),
        data = {}, tmp;
    for (var i = 0, l = params.length; i < l; i++) {
         tmp = params[i].split('=');
         data[tmp[0]] = tmp[1];
    }
    document.getElementById('here').innerHTML = data.name;
}

Description: javascript can't share data between different pages, and we must to use some solutions, e.g. URL get params (in my code i used this way), cookies, localStorage, etc. Store the name parameter in URL (?name=...) and in next.html parse URL and get all params from prev page.

PS. i'm an non-native english speaker, will you please correct my message, if necessary

If you want to only pass certain arguments, you can do so like this:

Foo.bar(TheClass, 'theMethod', 'arg1', 'arg2')

Foo.js

bar (obj, method, ...args) {
  obj[method](...args)
}

obj and method are used by the bar() method, while the rest of args are passed to the actual call.

Thank you very much for the replies!

Saggi Malachi, that query unfortunately sums the invoice amount in cases where there is more than one payment. Say there are two payments to a $39 invoice of $18 and $12. So rather than ending up with a result that looks like:

1   39.00   9.00

You'll end up with:

1   78.00   48.00

Charles Bretana, in the course of trimming my query down to the simplest possible query I (stupidly) omitted an additional table, customerinvoices, which provides a link between customers and invoices. This can be used to see invoices for which payments haven't made.

After much struggling, I think that the following query returns what I need it to:

SELECT DISTINCT i.invoiceid, i.amount, ISNULL(i.amount - p.amount, i.amount) AS amountdue
FROM invoices i
LEFT JOIN invoicepayments ip ON i.invoiceid = ip.invoiceid
LEFT JOIN customerinvoices ci ON i.invoiceid = ci.invoiceid
LEFT JOIN (
  SELECT invoiceid, SUM(p.amount) amount
  FROM invoicepayments ip 
  LEFT JOIN payments p ON ip.paymentid = p.paymentid
  GROUP BY ip.invoiceid
) p
ON p.invoiceid = ip.invoiceid
LEFT JOIN payments p2 ON ip.paymentid = p2.paymentid
LEFT JOIN customers c ON ci.customerid = c.customerid
WHERE c.customernumber='100'

Would you guys concur?

You can also look at the Date.getTime() API. That gives a long to which you can add your increment. Then create a new Date.

List<Date> dates = new ArrayList<Date>();
long interval = 1000 * 60 * 60; // 1 hour in millis
long endtime = ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
  dates.add(new Date(curTime));
  curTime += interval;
}

and maybe apache commons has something like this in DateUtils, or perhaps they have a CalendarUtils too :)

EDIT

including the start and enddate may not be possible if your interval is not perfect :)

Maybe something like this:

SELECT count(*) FROM user_tab_columns WHERE table_name = 'FOO'

this will count number of columns in a the table FOO

You can also just

select count(*) from all_tab_columns where owner='BAR' and table_name='FOO';

where the owner is schema and note that Table Names are upper case

The way that worked for me, was to use my external IP Address.

If you don't know what it is, just google What's My IP

Then use your IP address and set this in your domains for the captcha and it should start working ok.

Images must be downloaded in order to be viewed by the client. Videos are a similar case, in many scenarios. You can setup proxy scripts to serve the files out, but that doesn't really solve the issue of preventing the user from getting their own copy. For a more thorough discussion of this topic, see the question How can I prevent/make it hard to download my flash video?

Use css @keyframes

.elementToFadeInAndOut {
    opacity: 1;
    animation: fade 2s linear;
}


@keyframes fade {
  0%,100% { opacity: 0 }
  50% { opacity: 1 }
}

here is a DEMO

.elementToFadeInAndOut {_x000D_
    width:200px;_x000D_
    height: 200px;_x000D_
    background: red;_x000D_
    -webkit-animation: fadeinout 4s linear forwards;_x000D_
    animation: fadeinout 4s linear forwards;_x000D_
}_x000D_
_x000D_
@-webkit-keyframes fadeinout {_x000D_
  0%,100% { opacity: 0; }_x000D_
  50% { opacity: 1; }_x000D_
}_x000D_
_x000D_
@keyframes fadeinout {_x000D_
  0%,100% { opacity: 0; }_x000D_
  50% { opacity: 1; }_x000D_
}

<div class=elementToFadeInAndOut></div>

Reading: Using CSS animations

You can clean the code by doing this:

.elementToFadeInAndOut {_x000D_
    width:200px;_x000D_
    height: 200px;_x000D_
    background: red;_x000D_
    -webkit-animation: fadeinout 4s linear forwards;_x000D_
    animation: fadeinout 4s linear forwards;_x000D_
    opacity: 0;_x000D_
}_x000D_
_x000D_
@-webkit-keyframes fadeinout {_x000D_
  50% { opacity: 1; }_x000D_
}_x000D_
_x000D_
@keyframes fadeinout {_x000D_
  50% { opacity: 1; }_x000D_
}

<div class=elementToFadeInAndOut></div>

Note that one difference between git remote --prune and git fetch --prune is being fixed, with commit 10a6cc8, by Tom Miller (tmiller) (for git 1.9/2.0, Q1 2014):

When we have a remote-tracking branch named "frotz/nitfol" from a previous fetch, and the upstream now has a branch named "**frotz"**, fetch would fail to remove "frotz/nitfol" with a "git fetch --prune" from the upstream.
git would inform the user to use "git remote prune" to fix the problem.

So: when a upstream repo has a branch ("frotz") with the same name as a branch hierarchy ("frotz/xxx", a possible branch naming convention), git remote --prune was succeeding (in cleaning up the remote tracking branch from your repo), but git fetch --prune was failing.

Not anymore:

Change the way "fetch --prune" works by moving the pruning operation before the fetching operation.
This way, instead of warning the user of a conflict, it automatically fixes it.

You can do this easily with Google GSON.

Let's say you have a class called User with the fields user, width, and height and you want to convert the following json string to the User object.

{"name":"MyNode", "width":200, "height":100}

You can easily do so, without having to cast (keeping nimcap's comment in mind ;) ), with the following code:

Gson gson = new Gson(); 
final User user = gson.fromJson(jsonString, User.class);

Where jsonString is the above JSON String.

For more information, please look into https://code.google.com/p/google-gson/

The other answers already do a fantastic job explaining what declarative programming is, so I'm just going to provide some examples of why that might be useful.

Context Independence

Declarative Programs are context-independent. Because they only declare what the ultimate goal is, but not the intermediary steps to reach that goal, the same program can be used in different contexts. This is hard to do with imperative programs, because they often depend on the context (e.g. hidden state).

Take yacc as an example. It's a parser generator aka. compiler compiler, an external declarative DSL for describing the grammar of a language, so that a parser for that language can automatically be generated from the description. Because of its context independence, you can do many different things with such a grammar:

• Generate a C parser for that grammar (the original use case for yacc)
• Generate a C++ parser for that grammar
• Generate a Java parser for that grammar (using Jay)
• Generate a C# parser for that grammar (using GPPG)
• Generate a Ruby parser for that grammar (using Racc)
• Generate a tree visualization for that grammar (using GraphViz)
• simply do some pretty-printing, fancy-formatting and syntax highlighting of the yacc source file itself and include it in your Reference Manual as a syntactic specification of your language

And many more …

Optimization

Because you don't prescribe the computer which steps to take and in what order, it can rearrange your program much more freely, maybe even execute some tasks in parallel. A good example is a query planner and query optimizer for a SQL database. Most SQL databases allow you to display the query that they are actually executing vs. the query that you asked them to execute. Often, those queries look nothing like each other. The query planner takes things into account that you wouldn't even have dreamed of: rotational latency of the disk platter, for example or the fact that some completely different application for a completely different user just executed a similar query and the table that you are joining with and that you worked so hard to avoid loading is already in memory anyway.

There is an interesting trade-off here: the machine has to work harder to figure out how to do something than it would in an imperative language, but when it does figure it out, it has much more freedom and much more information for the optimization stage.

!!! KIVY !!!

I was amazed seeing that no one mentioned Kivy!!!

I have once done a project using Tkinter, although they do advocate that it has improved a lot, it still gives me a feel of windows 98, so I switched to Kivy.

I have been following a tutorial series if it helps...

Just to give an idea of how kivy looks, see this (The project I am working on):

And I have been working on it for barely a week now ! The benefits for Kivy you ask? Check this

The reason why I chose this is, its look and that it can be used in mobile as well.

Also internationalization.

I fooled around with this some a while back. Did this in my model:

[Display(Name = "XXX", ResourceType = typeof(Labels))]

I had a separate class library for all the resources, so I had Labels.resx, Labels.culture.resx, etc.

In there I had key = XXX, value = "meaningful string in that culture."

As mentioned earlier by firelynx if dtype is explicitly specified and there is mixed data that is not compatible with that dtype then loading will crash. I used a converter like this as a workaround to change the values with incompatible data type so that the data could still be loaded.

def conv(val):
    if not val:
        return 0    
    try:
        return np.float64(val)
    except:        
        return np.float64(0)

df = pd.read_csv(csv_file,converters={'COL_A':conv,'COL_B':conv})

Here's a mmap example:

#include <sys/mman.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

/*
 * pvtmMmapAlloc - creates a memory mapped file area.  
 * The return value is a page-aligned memory value, or NULL if there is a failure.
 * Here's the list of arguments:
 * @mmapFileName - the name of the memory mapped file
 * @size - the size of the memory mapped file (should be a multiple of the system page for best performance)
 * @create - determines whether or not the area should be created.
 */

As far as I understand, the basic concept there is that you create small "services" that provide something useful to other systems and avoid building large systems that tend to do everything inside the system.

So you define a protocol which you will use for interaction (say, it might be SOAP web services) and let your "system-that-does-some-business-work" to interact with the small services to achieve your "big goal".

keep.update((0,1,2,3,4,5,6,7,8,9,10))

Or

keep.update(np.arange(11))

The error pretty much explains what the problem is: you are trying to include a file that is not there.

Try to use the full path to the file, using realpath(), and use dirname(__FILE__) to get your current directory:

require_once(realpath(dirname(__FILE__) . '/../includes/dbconn.inc'));

tl;dr

java.time.Instant                    // Represent a moment as seen in UTC. Internally, a count of nanoseconds since 1970-01-01T00:00Z.
.ofEpochSecond( 1_220_227_200L )     // Pass a count of whole seconds since the same epoch reference of 1970-01-01T00:00Z.

Know Your Data

People use various precisions in tracking time as a number since an epoch. So when you obtain some numbers to be interpreted as a count since an epoch, you must determine:

• What epoch?
  Many epochs dates have been used in various systems. Commonly used is POSIX/Unix time, where the epoch is the first moment of 1970 in UTC. But you should not assume this epoch.
• What precision?
  Are we talking seconds, milliseconds, microseconds, or nanoseconds since the epoch?
• What time zone?
  Usually a count since epoch is in UTC/GMT time zone, that is, has no time zone offset at all. But sometimes, when involving inexperienced or date-time ignorant programmers, there may be an implied time zone.

In your case, as others noted, you seem to have been given seconds since the Unix epoch. But you are passing those seconds to a constructor that expects milliseconds. So the solution is to multiply by 1,000.

Lessons learned:

• Determine, don't assume, the meaning of received data.
• Read the doc.

Your Data

Your data seems to be in whole seconds. If we assume an epoch of the beginning of 1970, and if we assume UTC time zone, then 1,220,227,200 is the first moment of the first day of September 2008.

Joda-Time

The java.util.Date and .Calendar classes bundled with Java are notoriously troublesome. Avoid them. Use instead either the Joda-Time library or the new java.time package bundled in Java 8 (and inspired by Joda-Time).

Note that unlike j.u.Date, a DateTime in Joda-Time truly knows its own assigned time zone. So in the example Joda-Time 2.4 code seen below, note that we first parse the milliseconds using the default assumption of UTC. Then, secondly, we assign a time zone of Paris to adjust. Same moment in the timeline of the Universe, but different wall-clock time. For demonstration, we adjust again, to UTC. Almost always better to explicitly specify your desired/expected time zone rather than rely on an implicit default (often the cause of trouble in date-time work).

We need milliseconds to construct a DateTime. So take your input of seconds, and multiply by a thousand. Note that the result must be a 64-bit long as we would overflow a 32-bit int.

long input = 1_220_227_200L;  // Note the "L" appended to long integer literals.
long milliseconds = ( input * 1_000L ); // Use a "long", not the usual "int". Note the appended "L".

Feed that count of milliseconds to constructor. That particular constructor assumes the count is from the Unix epoch of 1970. So adjust time zone as desired, after construction.

Use proper time zone names, a combination of continent and city/region. Never use 3 or 4 letter codes such as EST as they are neither standardized not unique.

DateTime dateTimeParis = new DateTime( milliseconds ).withZone( DateTimeZone.forID( "Europe/Paris" ) );

For demonstration, adjust the time zone again.

DateTime dateTimeUtc = dateTimeParis.withZone( DateTimeZone.UTC );
DateTime dateTimeMontréal = dateTimeParis.withZone( DateTimeZone.forID( "America/Montreal" ) );

Dump to console. Note how the date is different in Montréal, as the new day has begun in Europe but not yet in America.

System.out.println( "dateTimeParis: " + dateTimeParis );
System.out.println( "dateTimeUTC: " + dateTimeUtc );
System.out.println( "dateTimeMontréal: " + dateTimeMontréal );

When run.

dateTimeParis: 2008-09-01T02:00:00.000+02:00
dateTimeUTC: 2008-09-01T00:00:00.000Z
dateTimeMontréal: 2008-08-31T20:00:00.000-04:00

java.time

The makers of Joda-Time have asked us to migrate to its replacement, the java.time framework as soon as is convenient. While Joda-Time continues to be actively supported, all future development will be done on the java.time classes and their extensions in the ThreeTen-Extra project.

The java-time framework is defined by JSR 310 and built into Java 8 and later. The java.time classes have been back-ported to Java 6 & 7 on the ThreeTen-Backport project and to Android in the ThreeTenABP project.

An Instant is a moment on the timeline in UTC with a resolution of nanoseconds. Its epoch is the first moment of 1970 in UTC.

Instant instant = Instant.ofEpochSecond( 1_220_227_200L );

Apply an offset-from-UTC ZoneOffset to get an OffsetDateTime.

Better yet, if known, apply a time zone ZoneId to get a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Most of the answers provided here address the number of incoming requests to your backend webservice, not the number of outgoing requests you can make from your ASP.net application to your backend service.

It's not your backend webservice that is throttling your request rate here, it is the number of open connections your calling application is willing to establish to the same endpoint (same URL).

You can remove this limitation by adding the following configuration section to your machine.config file:

<configuration>
  <system.net>
    <connectionManagement>
      <add address="*" maxconnection="65535"/>
    </connectionManagement>
  </system.net>
</configuration>

You could of course pick a more reasonable number if you'd like such as 50 or 100 concurrent connections. But the above will open it right up to max. You can also specify a specific address for the open limit rule above rather than the '*' which indicates all addresses.

Hope this solves your problem!

EDIT: Oops, I do see you have the connection management mentioned in your code above. I will leave my above info as it is relevant for future enquirers with the same problem. However, please note there are currently 4 different machine.config files on most up to date servers!

There is .NET Framework v2 running under both 32-bit and 64-bit as well as .NET Framework v4 also running under both 32-bit and 64-bit. Depending on your chosen settings for your application pool you could be using any one of these 4 different machine.config files! Please check all 4 machine.config files typically located here:

• C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG
• C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG
• C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config
• C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config

Contrary to some of the other answers here, I say that you can use tabs however you want. vim was designed to be versatile and customizable, rather than forcing you to work according to predefined parameters. We all know how us programmers love to impose our "ethics" on everyone else, so this achievement is certainly a primary feature.

<C-w>gf is the tab equivalent of buffers' gf command. <C-PageUp> and <C-PageDown> will switch between tabs. (In Byobu, these two commands never work for me, but they work outside of Byobu/tmux. Alternatives are gt and gT.) <C-w>T will move the current window to a new tab page.

If you'd prefer that vim use an existing tab if possible, rather than creating a duplicate tab, add :set switchbuf=usetab to your .vimrc file. You can add newtab to the list (:set switchbuf=usetab,newtab) to force QuickFix commands that display compile errors to open in separate tabs. I prefer split instead, which opens the compile errors in a split window.

If you have mouse support enabled with :set mouse=a, you can interact with the tabs by clicking on them. There's also a + button by default that will create a new tab.

For the documentation on tabs, type :help tab-page in normal mode. (After you do that, you can practice moving a window to a tab using <C-w>T.) There's a long list of commands. Some of the window commands have to do with tabs, so you might want to look at that documentation as well via :help windows.

Addition: 2013-12-19

To open multiple files in vim with each file in a separate tab, use vim -p file1 file2 .... If you're like me and always forget to add -p, you can add it at the end, as vim follows the normal command line option parsing rules. Alternatively, you can add a bash alias mapping vim to vim -p.

Simulator -> Hardware -> Keyboard -> Toggle Software Keyboard should solve this problem.

If you need to resume an scp transfer from local to remote, try with rsync:

rsync --partial --progress --rsh=ssh local_file user@host:remote_file

Short version, as pointed out by @aurelijus-rozenas:

rsync -P -e ssh local_file user@host:remote_file

In general the order of args for rsync is

rsync [options] SRC DEST

static class Constants
{
    public const int MIN_LENGTH = 5;
    public const int MIN_WIDTH  = 5; 
    public const int MIN_HEIGHT = 6;
}

// elsewhere
public CBox()
{
    length = Constants.MIN_LENGTH; 
    width  = Constants.MIN_WIDTH; 
    height = Constants.MIN_HEIGHT;  
}

It may be little late but here are my two cents.

If you are using Java 8 then you can make use of computeIfPresent method. If the value for the specified key is present and non-null then it attempts to compute a new mapping given the key and its current mapped value.

final Map<String,Integer> map1 = new HashMap<>();
map1.put("A",0);
map1.put("B",0);
map1.computeIfPresent("B",(k,v)->v+1);  //[A=0, B=1]

We can also make use of another method putIfAbsent to put a key. If the specified key is not already associated with a value (or is mapped to null) then this method associates it with the given value and returns null, else returns the current value.

In case the map is shared across threads then we can make use of ConcurrentHashMap and AtomicInteger. From the doc:

An AtomicInteger is an int value that may be updated atomically. An AtomicInteger is used in applications such as atomically incremented counters, and cannot be used as a replacement for an Integer. However, this class does extend Number to allow uniform access by tools and utilities that deal with numerically-based classes.

We can use them as shown:

final Map<String,AtomicInteger> map2 = new ConcurrentHashMap<>();
map2.putIfAbsent("A",new AtomicInteger(0));
map2.putIfAbsent("B",new AtomicInteger(0)); //[A=0, B=0]
map2.get("B").incrementAndGet();    //[A=0, B=1]

One point to observe is we are invoking get to get the value for key B and then invoking incrementAndGet() on its value which is of course AtomicInteger. We can optimize it as the method putIfAbsent returns the value for the key if already present:

map2.putIfAbsent("B",new AtomicInteger(0)).incrementAndGet();//[A=0, B=2]

On a side note if we plan to use AtomicLong then as per documentation under high contention expected throughput of LongAdder is significantly higher, at the expense of higher space consumption. Also check this question.

SELECT * FROM Table_Name LIMIT 5;

It is one of the MIME type, in this case you are reponse header MIME type to text/html it means it displays html type. It is a information to browser. There are other types you can set to display excel, zip etc. Please see MIME Type for more information

You just need to name the anonymous property the same on both sides

on new { t1.ProjectID, SecondProperty = true } equals 
   new { t2.ProjectID, SecondProperty = t2.Completed } into j1

Based on the comments of @svick, here is another implementation that might make more sense:

from t1 in Projects
from t2 in Tasks.Where(x => t1.ProjectID == x.ProjectID && x.Completed == true)
                .DefaultIfEmpty()
select new { t1.ProjectName, t2.TaskName }

You could also use this existing solution. The demo is here. It looks like youtube loading bar. I just found it and added it to my own project.

You can use the "-r" option to set the sender address:

mail -r [email protected] -s ...

In case you also want to include your real name in the from-field, you can use the following format

mail -r "[email protected] (My Name)" -s "My Subject" ...

Perhaps you can do it while registering your root with RouterModule. You can pass a second object with property useHash:true like the below:

import { NgModule }       from '@angular/core';
import { BrowserModule  } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
import { ROUTES }   from './app.routes';

@NgModule({
    declarations: [AppComponent],
    imports: [BrowserModule],
    RouterModule.forRoot(ROUTES ,{ useHash: true }),],
    providers: [],
    bootstrap: [AppComponent],
})
export class AppModule {}

You can use column indices (letters) like this:

import pandas as pd
import numpy as np
file_loc = "path.xlsx"
df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")
print(df)

[Corresponding documentation][1]:

usecolsint, str, list-like, or callable default None

• If None, then parse all columns.
• If str, then indicates comma separated list of Excel column letters and column ranges (e.g. “A:E” or “A,C,E:F”). Ranges are inclusive of both sides.
• If list of int, then indicates list of column numbers to be parsed.

• If list of string, then indicates list of column names to be parsed.

  New in version 0.24.0.

• If callable, then evaluate each column name against it and parse the column if the callable returns True.

Returns a subset of the columns according to behavior above.

New in version 0.24.0.

As described by Gideon, this is a known issue with Chrome that has been open for more than 5 years with no apparent interest in fixing it.

Unfortunately, in my case, the window.onunload = function() { debugger; } workaround didn't work either. So far the best workaround I've found is to use Firefox, which does display response data even after a navigation. The Firefox devtools also have a lot of nice features missing in Chrome, such as syntax highlighting the response data if it is html and automatically parsing it if it is JSON.

@echo off
title Test

echo Select a language. (de/en)
set /p language=

IF /i "%language%"=="de" goto languageDE
IF /i "%language%"=="en" goto languageEN

echo Not found.
goto commonexit

:languageDE
echo German
goto commonexit

:languageEN
echo English
goto commonexit

:commonexit
pause

The point is that batch simply continues through instructions, line by line until it reaches a goto, exit or end-of-file. It has no concept of sections to control flow.

Hence, entering de would jump to :languagede then simply continue executing instructions until the file ends, showing de then en then not found.

Check via Google, there are lots of examples, see here for one.

    o = win32com.client.Dispatch("Outlook.Application")
    s.Logon(profilename)

    Msg = o.CreateItem(0)
    Msg.To = recipient

    Msg.CC = "moreaddresses here"
    Msg.BCC = "address"

    Msg.Subject = subject
    Msg.Body = text

    attachment1 = "Path to attachment no. 1"
    attachment2 = "Path to attachment no. 2"
    Msg.Attachments.Add(attachment1)
    Msg.Attachments.Add(attachment2)

AFAIK, you can't do it with CSS alone. CSS has content rule but even that can be used to insert content before or after an element using pseudo selectors. You need to resort to javascript for that OR use placeholder attribute if you are using HTML5 as pointed out by @Blender.

An executable file needs to have permissions for execute set before you can execute it.

In your machine where you are building the docker image (not inside the docker image itself) try running:

ls -la path/to/directory

The first column of the output for your executable (in this case docker-entrypoint.sh) should have the executable bits set something like:

-rwxrwxr-x

If not then try:

chmod +x docker-entrypoint.sh

and then build your docker image again.

Docker uses it's own file system but it copies everything over (including permissions bits) from the source directories.

Not using the standard API, no. You can roll your own doing something like this:

class Duration {
    private final TimeUnit unit;
    private final long length;
    // ...
}

Or you can use Joda:

DateTime a = ..., b = ...;
Duration d = new Duration(a, b);

What's going on is that you're returning right after the first line of the file doesn't match the id you're looking for. You have to do this:

def query(id):
    for line in file:
        table = {}
        (table["ID"],table["name"],table["city"]) = line.split(";")
        if id == int(table["ID"]):
             file.close()
             return table
    # ID not found; close file and return empty dict
    file.close()
    return {}

Who says your main class is in a file on a local harddisk? Classes are more often bundled inside JAR files, and sometimes loaded over the network or even generated on the fly.

So what is it that you actually want to do? There is probably a way to do it that does not make assumptions about where classes come from.

this could work for you.

using System.Linq;

DirectoryInfo info = new DirectoryInfo("PATH_TO_DIRECTORY_HERE");
FileInfo[] files = info.GetFiles().OrderBy(p => p.CreationTime).ToArray();
foreach (FileInfo file in files)
{
    // DO Something...
}

Top comment has a broken link to the console.log documentation for Firebug, so here is a link to the wiki article about Console. I started using it and am quite satisfied with it as an alternative to PHP's print_r().

Also of note is that Firebug gives you access to returned JSON objects even without you manually logging them:

• In the console you can see the url of the AJAX response.
• Click the triangle to expand the response and see details.
• Click the JSON tab in the details.
• You will see the response data organized with expansion triangles.

This method take a couple more clicks to get at the data but doesn't require any additions in your actual javascript and doesn't shift your focus in Firebug out of the console (using console.log creates a link to the DOM section of firebug, forcing you to click back to console after).

For my money I'd rather click a couple more times when I want to inspect rather than mess around with the log, especially since keeps the console neat by not adding any additional cruft.

Here is a worked-out solution based on the other suggestions:

#include <string>
#include <iostream>
#include <clocale>
#include <locale>
#include <vector>

int main() {
  std::setlocale(LC_ALL, "");
  const std::wstring ws = L"hëllö";
  const std::locale locale("");
  typedef std::codecvt<wchar_t, char, std::mbstate_t> converter_type;
  const converter_type& converter = std::use_facet<converter_type>(locale);
  std::vector<char> to(ws.length() * converter.max_length());
  std::mbstate_t state;
  const wchar_t* from_next;
  char* to_next;
  const converter_type::result result = converter.out(state, ws.data(), ws.data() + ws.length(), from_next, &to[0], &to[0] + to.size(), to_next);
  if (result == converter_type::ok or result == converter_type::noconv) {
    const std::string s(&to[0], to_next);
    std::cout <<"std::string =     "<<s<<std::endl;
  }
}

This will usually work for Linux, but will create problems on Windows.

Are you targeting the .NET 4 framework or the .NET 4 Client Profile?

If you're targeting the latter, you won't find that class. You also may be missing a reference, likely to an extensions dll.

One more idea that worked. It's really silly, but, apparently, the default target OS setting (bottom right corner of the screen) is Vista / Windows Server 2008. As we're past the 10 year mark, it is likely that your Powershell script will not be compatible to these.

Changing the target to Windows Server 2016, as shown on the screenshot below, did the trick for me.

Use the code below,

TableRow _tableRow =(TableRow)findViewById(R.id.tableRowMainBody);
tableRow.requestFocus();

that should work.

Generally, EXC_BAD_INSTRUCTION means that there was an assertion failure in your code. A wild guess, your Screen.text is not an integer. Double check its type.

While it does look simple enough to implement on your own with a timeout and a couple of mouse event handlers, it gets a bit more complicated when you consider cases like click-drag-release, supporting both press and long-press on the same element, and working with touch devices like the iPad. I ended up using the longclick jQuery plugin (Github), which takes care of that stuff for me. If you only need to support touchscreen devices like mobile phones, you might also try the jQuery Mobile taphold event.

Try removing the position from header and add overflow to container:

#container {
    position:relative;
    width:80%;
    height:auto;
    overflow:auto;
}
#header {
    width:80%;
    height:50px;
    padding:10px;
}

Try setting these values, it solves problem in fast-cgi

fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;

To get the smallest or largest item in a list, use the built-in min and max functions:

 lo = min(L)
 hi = max(L)  

As with sort, you can pass in a "key" argument that is used to map the list items before they are compared:

 lo = min(L, key=int)
 hi = max(L, key=int)

http://effbot.org/zone/python-list.htm

Looks like you could use the max function if you map it correctly for strings and use that as the comparison. I would recommend just finding the max once though of course, not for each element in the list.

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.

I know this is late but it could help somebody.

You can use a constraintLayout and add the following property in the xml,

        android:elevation="4dp"

Running command prompt as Administrator solved the problem for me. I did not have to move M2 or M2_HOME under system variables.

I have changed Matt's class so it can be reused in any project without printing all its checks on Console and returning a simple string with correct max version installed.

getting following error

It happens:  Error: 
      ngModel cannot be used to register form controls with a parent formGroup directive.  Try using
      formGroup's partner directive "formControlName" instead.  Example:

First off, you're not dealing with a "JSON object." You're dealing with a JavaScript object. JSON is a textual notation, but if your example code works ([0].amount), you've already deserialized that notation into a JavaScript object graph. (What you've quoted isn't valid JSON at all; in JSON, the keys must be in double quotes. What you've quoted is a JavaScript object literal, which is a superset of JSON.)

Here, length of this array is 2.

No, it's 3.

So, i need to get the name (like amount or job... totally four name) and also to count how many names are there?

If you're using an environment that has full ECMAScript5 support, you can use Object.keys (spec | MDN) to get the enumerable keys for one of the objects as an array. If not (or if you just want to loop through them rather than getting an array of them), you can use for..in:

var entry;
var name;
entry = array[0];
for (name in entry) {
    // here, `name` will be "amount", "job", "month", then "year" (in no defined order)
}

Full working example:

(function() {_x000D_
  _x000D_
  var array = [_x000D_
    {_x000D_
      amount: 12185,_x000D_

      job: "GAPA",_x000D_
      month: "AUGUST",_x000D_
      year: "2010"_x000D_
    }_x000D_

  _x000D_
  var entry;_x000D_
  var name;_x000D_
  var count;_x000D_
  _x000D_
  entry = array[0];_x000D_
  _x000D_
  display("Keys for entry 0:");_x000D_
  count = 0;_x000D_
  for (name in entry) {_x000D_

  }_x000D_
  display("Total enumerable keys: " + count);_x000D_
_x000D_
  // === Basic utility functions_x000D_
  _x000D_
  function display(msg) {_x000D_
    var p = document.createElement('p');_x000D_
    p.innerHTML = msg;_x000D_
    document.body.appendChild(p);_x000D_
  }_x000D_
  _x000D_
})();

Since you're dealing with raw objects, the above for..in loop is fine (unless someone has committed the sin of mucking about with Object.prototype, but let's assume not). But if the object you want the keys from may also inherit enumerable properties from its prototype, you can restrict the loop to only the object's own keys (and not the keys of its prototype) by adding a hasOwnProperty call in there:

for (name in entry) {
  if (entry.hasOwnProperty(name)) {
    display(name);
    ++count;
  }
}

// in foo.h
class Foo {
    static const unsigned char* Msg;
};

// in foo.cpp
static const unsigned char Foo_Msg_data[] = {0x00,0x01};
const unsigned char* Foo::Msg = Foo_Msg_data;

There is another time when using getBean makes sense. If you're reconfiguring a system that already exists, where the dependencies are not explicitly called out in spring context files. You can start the process by putting in calls to getBean, so that you don't have to wire it all up at once. This way you can slowly build up your spring configuration putting each piece in place over time and getting the bits lined up properly. The calls to getBean will eventually be replaced, but as you understand the structure of the code, or lack there of, you can start the process of wiring more and more beans and using fewer and fewer calls to getBean.

The topic is 'Embed image in a button element', and the question using plain HTML. I do this using the span tag in the same way that glyphicons are used in bootstrap. My image is 16 x 16px and can be any format.

Here's the plain HTML that answers the question:

<button type="button"><span><img src="images/xxx.png" /></span>&nbsp;Click Me</button>

In addition to the other answers, Class defines the method === to test whether an object is an instance of that class.

• o.class class of o.
• o.instance_of? c determines whether o.class == c
• o.is_a? c Is o an instance of c or any of it's subclasses?
• o.kind_of? c synonym for *is_a?*
• c === o for a class or module, determine if *o.is_a? c* (String === "s" returns true)

you need to do one step:

run->cmd

run "c:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i"

Thats it

I'd install Tortoise Hg (a free GUI for Mercurial) and use that. You can then just right-click on a revision you might want to return to - with all the commit messages there in front of your eyes - and 'Revert all files'. Makes it intuitive and easy to roll backwards and forwards between versions of a fileset, which can be really useful if you are looking to establish when a problem first appeared.

If space is going to be an issue, have a 3rd table Tags(Tag_Id, Title) to store the text for the tag and then change your Tags table to be (Tag_Id, Item_Id). Those two values should provide a unique composite primary key as well.

Judging by your other post: How to Get the inner text of a span in PHP. You're quite new to web programming, and need to learn about the differences between code on the client (JavaScript) and code on the server (PHP).

As for the correct approach to grabbing the span text from the client I recommend Johns answer.

These are a good place to get started.

Also I recommend using jQuery (Once you've got some JavaScript practice) it will eliminate most of the cross-browser compatability issues that you're going to have. But don't use it as a crutch to learn on, it's good to understand JavaScript too. http://jquery.com/

Java 8 added a new way of making Comparators that reduces the amount of code you have to write, Comparator.comparing. Also check out Comparator.reversed

Here's a sample

import org.junit.Test;

import java.util.ArrayList;
import java.util.Comparator;
import java.util.List;

import static org.junit.Assert.assertTrue;

public class ComparatorTest {

    @Test
    public void test() {
        List<Person> peopleList = new ArrayList<>();
        peopleList.add(new Person("A", 1000));
        peopleList.add(new Person("B", 1));
        peopleList.add(new Person("C", 50));
        peopleList.add(new Person("Z", 500));
        //sort by name, ascending
        peopleList.sort(Comparator.comparing(Person::getName));
        assertTrue(peopleList.get(0).getName().equals("A"));
        assertTrue(peopleList.get(peopleList.size() - 1).getName().equals("Z"));
        //sort by name, descending
        peopleList.sort(Comparator.comparing(Person::getName).reversed());
        assertTrue(peopleList.get(0).getName().equals("Z"));
        assertTrue(peopleList.get(peopleList.size() - 1).getName().equals("A"));
        //sort by age, ascending
        peopleList.sort(Comparator.comparing(Person::getAge));
        assertTrue(peopleList.get(0).getAge() == 1);
        assertTrue(peopleList.get(peopleList.size() - 1).getAge() == 1000);
        //sort by age, descending
        peopleList.sort(Comparator.comparing(Person::getAge).reversed());
        assertTrue(peopleList.get(0).getAge() == 1000);
        assertTrue(peopleList.get(peopleList.size() - 1).getAge() == 1);
    }

    class Person {

        String name;
        int age;

        Person(String n, int a) {
            name = n;
            age = a;
        }

        public String getName() {
            return name;
        }

        public int getAge() {
            return age;
        }

        public void setName(String name) {
            this.name = name;
        }

        public void setAge(int age) {
            this.age = age;
        }
    }

Normally when you try to select a node using xpath your xpath-engine will return null or equivalent if the node doesn't exists.

xpath: "/Consumers/Consumer/DataSources/Credit/CreditReport/AttachedXml"

If your using xsl check out this question for an answer:

xpath find if node exists

I) if you need to calculate the elapsed time in seconds between two timestamp columns try this:

SELECT 
    extract ( day from (end_timestamp - start_timestamp) )*86400 
    + extract ( hour from (end_timestamp - start_timestamp) )*3600 
    + extract ( minute from (end_timestamp - start_timestamp) )*60 
    + extract ( second from (end_timestamp - start_timestamp) ) 
FROM table_name

II) if you want to just show the time difference in character format try this:

SELECT to_char (end_timestamp - start_timestamp) FROM table_name

#!/usr/bin/python
file=open("D:\\zzzz\\names2.txt","r+")
wordcount={}
for word in file.read().split():
    if word not in wordcount:
        wordcount[word] = 1
    else:
        wordcount[word] += 1
for k,v in wordcount.items():
    print k, v

We can use splatting for this:

& $command @args

where @args (automatic variable $args) is splatted into array of parameters.

+1 to PleaseStand and here is my other hack:

after searching and found that the "cross ajax request" could not get response headers from XHR object, I gave up. and use iframe instead.

1. <iframe style="display:none"></iframe>
2. $("iframe").attr("src", "http://the_url_you_want_to_access")
//this is my aim!!!
3. $("iframe").contents().find('#someID').html()  

From the document.getElementsByTagName I guess you are running the javascript in a browser.

The traditional way to expose functionality to javascript running in the browser is calling a remote URL using AJAX. The X in AJAX is for XML, but nowadays everybody uses JSON instead of XML.

For example, using jQuery you can do something like:

$.getJSON('http://example.com/your/webservice?param1=x&param2=y', 
    function(data, textStatus, jqXHR) {
        alert(data);
    }
)

You will need to implement a python webservice on the server side. For simple webservices I like to use Flask.

A typical implementation looks like:

@app.route("/your/webservice")
def my_webservice():
    return jsonify(result=some_function(**request.args)) 

You can run IronPython (kind of Python.Net) in the browser with silverlight, but I don't know if NLTK is available for IronPython.

Your result is wrong for Java. Please provide some context how you arrived at it (your program, implementation and version of Java).

From the Java Language Specification

15.17.3 Remainder Operator %
[...]
The remainder operation for operands that are integers after binary numeric promotion (§5.6.2) produces a result value such that (a/b)*b+(a%b) is equal to a.

15.17.2 Division Operator /
[...]
Integer division rounds toward 0.

Since / is rounded towards zero (resulting in zero), the result of % should be negative in this case.

You have not included Launcher intent filter in activity you want to appear first, so it does not know which activity to start when application launches, for this tell the system by including launcher filter intent in manifest.xml

Although this is valid in HTML, you can't use an ID starting with an integer in CSS selectors.

As pointed out, you can use getElementById instead, but you can also still achieve the same with a querySelector:

document.querySelector("[id='22']")

If you wanted to do it that way...

$line = 0;

while (($buffer = fgets($fh)) !== FALSE) {
   if ($line == 1) {
       // This is the second line.
       break;
   }   
   $line++;
}

Alternatively, open it with file() and subscript the line with [1].

Try this out:

grep -i 'killed process' /var/log/messages

To run the batch file when the VM user logs in:

Drag the shortcut--the one that's currently on your desktop--(or the batch file itself) to Start - All Programs - Startup. Now when you login as that user, it will launch the batch file.

Another way to do the same thing is to save the shortcut or the batch file in %AppData%\Microsoft\Windows\Start Menu\Programs\Startup\.

As far as getting it to run full screen, it depends a bit what you mean. You can have it launch maximized by editing your batch file like this:

start "" /max "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" --comment "VM" --startvm "12dada4d-9cfd-4aa7-8353-20b4e455b3fa"

But if VirtualBox has a truly full-screen mode (where it hides even the taskbar), you'll have to look for a command-line parameter on VirtualBox.exe. I'm not familiar with that product.

I had a similar problem. The catalina.out logged this log Message

Apr 17, 2013 5:14:46 PM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart

Check the localhost.log in the tomcat log directory (in the same directory as catalina.out), to see the exception which caused this error.

Visual Studio's search in folders is by far the fastest I've found.

I believe it intelligently searches only text (non-binary) files, and subsequent searches in the same folder are extremely fast, unlike with the other tools (likely the text files fit in the windows disk cache).

VS2010 on a regular hard drive, no SSD, takes 1 minute to search a 20GB folder with 26k files, source code and binaries mixed up. 15k files are searched - the rest are likely skipped due to being binary files. Subsequent searches in the same folder are on the order of seconds (until stuff gets evicted form the cache).

The next closest I've found for the same folder was grepWin. Around 3 minutes. I excluded files larger than 2000KB (default). The "Include binary files" setting seems to do nothing in terms of speeding up the search, it looks like binary files are still touched (bug?), but they don't show up in the search results. Subsequent searches all take the same 3 minutes - can't take advantage of hard drive cache. If I restrict to files smaller than 200k, the initial search is 2.5min and subsequent searches are on the order of seconds, about as fast as VS - in the cache.

Agent Ransack and FileSeek are both very slow on that folder, around 20min, due to searching through everything, including giant multi-gigabyte binary files. They search at about 10-20MB per second according to Resource Monitor.

UPDATE: Agent Ransack can be set to search files of certain sizes, and using the <200KB cutoff it's 1:15min for a fresh search and 5s for subsequent searches. Faster than grepWin and as fast as VS overall. It's actually pretty nice if you want to keep several searches in tabs and you don't want to pollute the VS recently searched folders list, and you want to keep the ability to search binaries, which VS doesn't seem to wanna do. Agent Ransack also creates an explorer context menu entry, so it's easy to launch from a folder. Same as grepWin but nicer UI and faster.

My new search setup is Agent Ransack for contents and Everything for file names (awesome tool, instant results!).

path is pointing to a subfolder under c:\Documents & Settings

That's right. ClickOnce applications are installed under the profile of the user who installed them. Did you take the path that retrieving the info from the executing assembly gave you, and go check it out?

On windows Vista and Windows 7, you will find the ClickOnce cache here:

c:\users\username\AppData\Local\Apps\2.0\obfuscatedfoldername\obfuscatedfoldername

On Windows XP, you will find it here:

C:\Documents and Settings\username\LocalSettings\Apps\2.0\obfuscatedfoldername\obfuscatedfoldername

instead of using iframe and depending on the third party`think about using flexpaper, or pdf.js.

I used PDF.js, it works fine for me. Here is the demo.

This works cross-browser, provides more accessibility and comes with less markup. ditch the div. Wrap the label

label{
     display: block; 
     height: 35px; 
     line-height: 35px; 
     border: 1px solid #000; 
}

input{margin-top:15px; height:20px}

<label for="name">Name: <input type="text" id="name" /></label>

There are a few steps you have to keep in mind.

• First, make sure you have turned off 2-way authentication of google account
• Second, allow access for less secure apps- https://myaccount.google.com/lesssecureapps

Now there are two scenarios If you are developing it in your local machine login to your google account in your browser, this way the google recognizes the machine.

If you have deployed the application onto a server then after the first request you will get an authentication error, so you have to give access to the server, just go here to give access- https://www.google.com/accounts/DisplayUnlockCaptcha

You could use the bootstrap grid system :

<div class="col-md-6 form-group">
    <label for="textbox1">Label1</label>
    <input class="form-control" id="textbox1" type="text"/>
</div>
<div class="col-md-6 form-group">
    <label for="textbox2">Label2</label>
    <input class="form-control" id="textbox2" type="text"/>
</div>
<span class="clearfix">

http://getbootstrap.com/css/#grid

Is that what you want to achieve?

your validation should be occur before your event suppose you are going to submit your form.

anyway if you want this on onchange, so here is code.

function valid(id)
{
    var textVal=document.getElementById(id).value;
    if (!textVal.match(/\S/)) 
    {
        alert("Field is blank");
        return false;
    } 
    else 
    {
        return true;
    }
 }

For Dot Net Core 3, Microsoft.Data.SqlClient should be used.

This path of the schema location is wrong:

http://www.springframework.org/schema/beans

The correct path should end with /:

http://www.springframework.org/schema/beans/

You can use require as well to render images like

//then in the render function of Jsx insert the mainLogo variable

class NavBar extends Component {
  render() {
    return (
      <nav className="nav" style={nbStyle}>
        <div className="container">
          //right below here
          <img src={require('./logoWhite.png')} style={nbStyle.logo} alt="fireSpot"/>
        </div>
      </nav>
    );
  }
}

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

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

I had a similar problem. I needed to get the last version of page content translation, in other words - to get that specific record which has highest number in version column. So I select all records ordered by version and then take the first row from result (by using LIMIT clause).

SELECT *
FROM `page_contents_translations`
ORDER BY version DESC
LIMIT 1

The evaluation of condition resulted in an NA. The if conditional must have either a TRUE or FALSE result.

if (NA) {}
## Error in if (NA) { : missing value where TRUE/FALSE needed

This can happen accidentally as the results of calculations:

if(TRUE && sqrt(-1)) {}
## Error in if (TRUE && sqrt(-1)) { : missing value where TRUE/FALSE needed

To test whether an object is missing use is.na(x) rather than x == NA.

See also the related errors:

Error in if/while (condition) { : argument is of length zero

Error in if/while (condition) : argument is not interpretable as logical

if (NULL) {}
## Error in if (NULL) { : argument is of length zero

if ("not logical") {}
## Error: argument is not interpretable as logical

if (c(TRUE, FALSE)) {}
## Warning message:

SOAPAction is required in SOAP 1.1 but can be empty ("").

See https://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383528

"The header field value of empty string ("") means that the intent of the SOAP message is provided by the HTTP Request-URI."

Try setting SOAPAction=""

ping localhost -n (your time) >nul

example

@echo off
title Test
echo hi
ping localhost -n 3 >nul && :: will wait 3 seconds before going next command (it will not display)
echo bye! && :: still wont be any spaces (just below the hi command)
ping localhost -n 2 >nul && :: will wait 2 seconds before going to next command (it will not display)
@exit

C++ is a standardized language. Visual C++ is a product that more or less implements that standard. You can write portable C++ using Visual C++, but you can also use Microsoft-only extensions that destroy your portability but enhance your productivity. This is a trade-off. You have to decide what appeals most to you.

I've maintained big desktop apps that were written in Visual C++, so that is perfectly feasible. From what I know of Visual Basic, the main advantage seems to be that the first part of the development cycle may be done faster than when using Visual C++, but as the complexity of a project increases, C++ programs tend to be more maintainable (If the programmers are striving for maintainability, that is).

An answer for the year 2021

The question is still very popular, but all the answers are seriously outdated. All Java EE components were split off into various Jakarta projects and JSTL is no different. So here are the correct Maven dependencies as of today:

<dependency>
    <groupId>jakarta.servlet.jsp.jstl</groupId>
    <artifactId>jakarta.servlet.jsp.jstl-api</artifactId>
    <version>1.2.7</version>
</dependency>
<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>jakarta.servlet.jsp.jstl</artifactId>
    <version>1.2.6</version>
</dependency>

Yes, the versions and groupIds do not match, but that's a quirk of the project's current state.

If you already have a dataframe, this is the fastest way:

In [1]: columns = ["col{}".format(i) for i in range(10)]
In [2]: orig_df = pd.DataFrame(np.ones((10, 10)), columns=columns)
In [3]: %timeit d = pd.DataFrame(np.zeros_like(orig_df), index=orig_df.index, columns=orig_df.columns)
10000 loops, best of 3: 60.2 µs per loop

Compare to:

In [4]: %timeit d = pd.DataFrame(0, index = np.arange(10), columns=columns)
10000 loops, best of 3: 110 µs per loop

In [5]: temp = np.zeros((10, 10))
In [6]: %timeit d = pd.DataFrame(temp, columns=columns)
10000 loops, best of 3: 95.7 µs per loop

There is the $.parseXML function for this: http://api.jquery.com/jQuery.parseXML/

You can use it like this:

var xml = $.parseXML(yourfile.xml),
  $xml = $( xml ),
  $test = $xml.find('test');

console.log($test.text());

If you really want an object, you need a plugin for that. This plugin for instance, will convert your XML to JSON: http://www.fyneworks.com/jquery/xml-to-json/

@variable is very useful if calling stored procedures from an application written in Java , Python etc. There are ocassions where variable values are created in the first call and needed in functions of subsequent calls.

Side-note on PL/SQL (Oracle)

The advantage can be seen in Oracle PL/SQL where these variables have 3 different scopes:

• Function variable for which the scope ends when function exits.
• Package body variables defined at the top of package and outside all functions whose scope is the session and visibility is package.
• Package variable whose variable is session and visibility is global.

My Experience in PL/SQL

I have developed an architecture in which the complete code is written in PL/SQL. These are called from a middle-ware written in Java. There are two types of middle-ware. One to cater calls from a client which is also written in Java. The other other one to cater for calls from a browser. The client facility is implemented 100 percent in JavaScript. A command set is used instead of HTML and JavaScript for writing application in PL/SQL.

I have been looking for the same facility to port the codes written in PL/SQL to another database. The nearest one I have found is Postgres. But all the variables have function scope.

Opinion towards @ in MySQL

I am happy to see that at least this @ facility is there in MySQL. I don't think Oracle will build same facility available in PL/SQL to MySQL stored procedures since it may affect the sales of Oracle database.

I just found a way that allow you not directly access the status bar height, but calculate it.

Navigation Bar height - topLayoutGuide length = status bar height

Swift:

let statusBarHeight = self.topLayoutGuide.length-self.navigationController?.navigationBar.frame.height

self.topLayoutGuide.length is the top area that's covered by the translucent bar, and self.navigationController?.navigationBar.frame.height is the translucent bar excluding status bar, which is usually 44pt. So by using this method you can easily calculate the status bar height without worring about status bar height change due to phone calls.

An old thread I know but still super relevant to anyone coming across this.

Array.map has been suggested here which is an awesome method that I use all the time. Array.reduce was also mentioned...

I would personally use an Array.reduce for this use case. Why? Despite the code being slightly less clean/clear. It is a much more efficient than piping the map function to a join.

The reason for this is because Array.map has to loop over each element to return a new array with all of the names of the object in the array. Array.join then loops over the contents of array to perform the join.

You can improve the readability of jackweirdys reduce answer by using template literals to get the code on to a single line. "Supported in all modern browsers too"

// a one line answer to this question using modern JavaScript
x.reduce((a, b) => `${a.name || a}, ${b.name}`);

Python 2:

• raw_input() takes exactly what the user typed and passes it back as a string.

• input() first takes the raw_input() and then performs an eval() on it as well.

The main difference is that input() expects a syntactically correct python statement where raw_input() does not.

Python 3:

• raw_input() was renamed to input() so now input() returns the exact string.
• Old input() was removed.

If you want to use the old input(), meaning you need to evaluate a user input as a python statement, you have to do it manually by using eval(input()).

I don't have much experience with Flexbox but it seems to me that the forced height on the html and body tags cause the text to disappear on top when resized-- I wasn't able to test in IE but I found the same effect in Chrome.

I forked your fiddle and removed the height and width declarations.

body
{
    margin: 0;
}

It also seemed like the flex settings must be applied to other flex elements. However, applying display: flex to the .inner caused issues so I explicitly set the .inner to display: block and set the .outer to flex for positioning.

I set the minimum .outer height to fill the viewport, the display: flex, and set the horizontal and vertical alignment:

.outer
{
    display:flex;
    min-height: 100%;
    min-height: 100vh;
    align-items: center;
    justify-content: center;
}

I set .inner to display: block explicitly. In Chrome, it looked like it inherited flex from .outer. I also set the width:

.inner
{
    display:block;
    width: 80%;
}

This fixed the issue in Chrome, hopefully it might do the same in IE11. Here's my version of the fiddle: http://jsfiddle.net/ToddT/5CxAy/21/

1. Since the final variable is non-static, it can be initialized in constructor. But if you make it static it can not be initialized by constructor (because constructors are not static).
2. Addition to list is not expected to stop by making list final. final just binds the reference to particular object. You are free to change the 'state' of that object, but not the object itself.

if (!String.prototype.hasOwnProperty('addSlashes')) {
    String.prototype.addSlashes = function() {
        return this.replace(/&/g, '&') /* This MUST be the 1st replacement. */
             .replace(/'/g, ''') /* The 4 other predefined entities, required. */
             .replace(/"/g, '"')
             .replace(/\\/g, '\\\\')
             .replace(/</g, '&lt;')
             .replace(/>/g, '&gt;').replace(/\u0000/g, '\\0');
        }
}

Usage: alert(str.addSlashes());

Relative to the default size defined to that font.

If someone opens your page on a web browser, there's a default font and font size it uses.

I have been having exactly the same problem, and finding almost no information online about it. Nothing at all in the books. Finally I found this sober query on stackoverflow and (ha!) it was the final impetus I needed to set up an account here.

And I have a partial answer, but alas not a complete one.

First of all, realise that the default timeout for getCurrentPosition is infinite(!). That means that your error handler will never be called if getCurrentPosition hangs somewhere on the back end.

To ensure that you get a timeout, add the optional third parameter to your call to getCurrentPosition, for example, if you want the user to wait no more than 10 seconds before giving them a clue what is happening, use:

navigator.geolocation.getCurrentPosition(successCallback,errorCallback,{timeout:10000});

Secondly, I have experienced quite different reliability in different contexts. Here at home, I get a callback within a second or two, although the accuracy is poor.

At work however, I experience quite bizarre variations in behavior: Geolocation works on some computers all the time (IE excepted, of course), others only work in chrome and safari but not firefox (gecko issue?), others work once, then subsequently fail - and the pattern changes from hour to hour, from day to day. Sometimes you have a 'lucky' computer, sometimes not. Perhaps slaughtering goats at full moon would help?

I have not been able to fathom this, but I suspect that the back end infrastructure is more uneven than advertised in the various gung-ho books and websites that are pushing this feature. I really wish that they would be a bit more straight about how flakey this feature is, and how important that timeout setting is, if you want your error handler to work properly.

I have been trying to teach this stuff to students today, and had the embarassing situation where my own computer (on the projector and several large screens) was failing silently, whereas about 80% of the students were getting a result almost instantly (using the exact same wireless network). It's very difficult to resolve these issues when my students are also making typos and other gaffes, and when my own pc is also failing.

Anyway, I hope this helps some of you guys. Thanks for the sanity check!

Just use the method .decode('base64') and go to be happy.

You need, too, to detect the mimetype/extension of the image, as you can save it correctly, in a brief example, you can use the code below for a django view:

def receive_image(req):
    image_filename = req.REQUEST["image_filename"] # A field from the Android device
    image_data = req.REQUEST["image_data"].decode("base64") # The data image
    handler = open(image_filename, "wb+")
    handler.write(image_data)
    handler.close()

And, after this, use the file saved as you want.

Simple. Very simple. ;)

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

If you're using Oracle, then a feature called analytics will do the trick. It looks like this:

select id, age, count(*) over (partition by age) from students;

If you aren't using Oracle, then you'll need to join back to the counts:

select a.id, a.age, b.age_count
  from students a
  join (select age, count(*) as age_count
          from students
         group by age) b
    on a.age = b.age

First of all, 2 thing that we need to understand

Client

• it make request to specific server

  bindService(new 
      Intent("com.android.vending.billing.InAppBillingService.BIND"),
          mServiceConn, Context.BIND_AUTO_CREATE);`
  

here mServiceConn is instance of ServiceConnection class(inbuilt) it is actually interface that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.

Server

• It handle the request of client and make replica of it's own which is private to client only who send request and this replica of server runs on different thread.

Now at client side, how to access all the method of server?

• server send response with IBind Object.so IBind object is our handler which access all the method of service by using (.) operator.

  MyService myService;
  public ServiceConnection myConnection = new ServiceConnection() {
      public void onServiceConnected(ComponentName className, IBinder binder) {
          Log.d("ServiceConnection","connected");
          myService = binder;
      }
      //binder comes from server to communicate with method's of 
  
      public void onServiceDisconnected(ComponentName className) {
          Log.d("ServiceConnection","disconnected");
          myService = null;
      }
  }
  

now how to call method which lies in service

myservice.serviceMethod();

here myService is object and serviceMethode is method in service. And by this way communication is established between client and server.

Maven plugin uses a settings file where the configuration can be set. Its path is available in Eclipse at Window|Preferences|Maven|User Settings. If the file doesn't exist, create it and put on something like this:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies>
    <proxy>
      <id>myproxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>192.168.1.100</host>
      <port>6666</port>
      <username></username>
      <password></password>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
  </proxies>

  <activeProfiles/>
</settings>

After editing the file, it's just a matter of clicking on Update Settings button and it's done. I've just done it and it worked :)

LIKE does matching like wildcards char [*, ?] at the shell
LIKE '%suffix' - give me everything that ends with suffix. You couldn't do that with =
Depends on the case actually.

For our application, we had a client server architecture and we only allowed decrypting/encrypting data in the server level. Hence the JCE files are only needed there.

We had another problem where we needed to update a security jar on the client machines, through JNLP, it overwrites the libraries in${java.home}/lib/security/ and the JVM on first run.

That made it work.

You can do it with ViewModels like how you passed data from your controller to view.

Assume you have a viewmodel like this

public class ReportViewModel
{
   public string Name { set;get;}
}

and in your GET Action,

public ActionResult Report()
{
  return View(new ReportViewModel());
}

and your view must be strongly typed to ReportViewModel

@model ReportViewModel
@using(Html.BeginForm())
{
  Report NAme : @Html.TextBoxFor(s=>s.Name)
  <input type="submit" value="Generate report" />
}

and in your HttpPost action method in your controller

[HttpPost]
public ActionResult Report(ReportViewModel model)
{
  //check for model.Name property value now
  //to do : Return something
}

OR Simply, you can do this without the POCO classes (Viewmodels)

@using(Html.BeginForm())
{
   <input type="text" name="reportName" />
   <input type="submit" />
}

and in your HttpPost action, use a parameter with same name as the textbox name.

[HttpPost]
public ActionResult Report(string reportName)
{
  //check for reportName parameter value now
  //to do : Return something
}

EDIT : As per the comment

If you want to post to another controller, you may use this overload of the BeginForm method.

@using(Html.BeginForm("Report","SomeOtherControllerName"))
{
   <input type="text" name="reportName" />
   <input type="submit" />
}

Passing data from action method to view ?

You can use the same view model, simply set the property values in your GET action method

public ActionResult Report()
{
  var vm = new ReportViewModel();
  vm.Name="SuperManReport";
  return View(vm);
}

and in your view

@model ReportViewModel
<h2>@Model.Name</h2>
<p>Can have input field with value set in action method</p>
@using(Html.BeginForm())
{
  @Html.TextBoxFor(s=>s.Name)
  <input type="submit" />
}

You can escape quotation like this:

select 'it''s escaped'

result will be

it's escaped

To push all your branches, use either (replace REMOTE with the name of the remote, for example "origin"):

git push REMOTE '*:*'
git push REMOTE --all

To push all your tags:

git push REMOTE --tags

Finally, I think you can do this all in one command with:

git push REMOTE --mirror

However, in addition --mirror, will also push your remotes, so this might not be exactly what you want.

Several tips:

1. Put inserts/updates in a transaction.
2. For older versions of SQLite - Consider a less paranoid journal mode (pragma journal_mode). There is NORMAL, and then there is OFF, which can significantly increase insert speed if you're not too worried about the database possibly getting corrupted if the OS crashes. If your application crashes the data should be fine. Note that in newer versions, the OFF/MEMORY settings are not safe for application level crashes.
3. Playing with page sizes makes a difference as well (PRAGMA page_size). Having larger page sizes can make reads and writes go a bit faster as larger pages are held in memory. Note that more memory will be used for your database.
4. If you have indices, consider calling CREATE INDEX after doing all your inserts. This is significantly faster than creating the index and then doing your inserts.
5. You have to be quite careful if you have concurrent access to SQLite, as the whole database is locked when writes are done, and although multiple readers are possible, writes will be locked out. This has been improved somewhat with the addition of a WAL in newer SQLite versions.
6. Take advantage of saving space...smaller databases go faster. For instance, if you have key value pairs, try making the key an INTEGER PRIMARY KEY if possible, which will replace the implied unique row number column in the table.
7. If you are using multiple threads, you can try using the shared page cache, which will allow loaded pages to be shared between threads, which can avoid expensive I/O calls.
8. Don't use !feof(file)!

I've also asked similar questions here and here.

I think you should have a directory per container with a Dockerfile (no extension) in it. For example:

  /db/Dockerfile
  /web/Dockerfile
  /api/Dockerfile

When you build just use the directory name, Docker will find the Dockerfile. e.g:

docker build -f ./db .

You can initialize an array by writing actual values it holds in curly braces on the right hand side like:

String[] strArr = { "one", "two", "three"};
int[] numArr = { 1, 2, 3};

In the same manner two-dimensional array or array-of-arrays holds an array as a value, so:

String strArrayOfArrays = { {"a", "b", "c"}, {"one", "two", "three"} };

Your example shows exactly that

double m[][] = {
    {0*0,1*0,2*0,3*0},
    {0*1,1*1,2*1,3*1},
    {0*2,1*2,2*2,3*2},
    {0*3,1*3,2*3,3*3}
};

But also the multiplication of number will also be performed and its the same as:

double m[][] = { {0, 0, 0, 0}, {0, 1, 2, 3}, {0, 2, 4, 6}, {0, 3, 6, 9} };

found this on Zurb's github

In case you want to do some more custom styling. Here's all the default CSS for webkit rendering of the date components.

input[type="date"] {
     -webkit-align-items: center;
     display: -webkit-inline-flex;
     font-family: monospace;
     overflow: hidden;
     padding: 0;
     -webkit-padding-start: 1px;
}

input::-webkit-datetime-edit {
    -webkit-flex: 1;
    -webkit-user-modify: read-only !important;
    display: inline-block;
    min-width: 0;
    overflow: hidden;
}

input::-webkit-datetime-edit-fields-wrapper {
    -webkit-user-modify: read-only !important;
    display: inline-block;
    padding: 1px 0;
    white-space: pre;
}

Call your hosting company and either have them set up regular log backups or set the recovery model to simple. I'm sure you know what informs the choice, but I'll be explicit anyway. Set the recovery model to full if you need the ability to restore to an arbitrary point in time. Either way the database is misconfigured as is.

The Java system property System.getProperty(...) to consult is "java.runtime.name". This will distinguish between "OpenJDK Runtime Environment" and "Java(TM) SE Runtime Environment". They both have the same vendor - "Oracle Corporation".

This property is also included in the output for java -version.

See Should my constructors use "initialization lists" or "assignment"?

Briefly: in your specific case, it does not change anything. But:

• for class/struct members with constructors, it may be more efficient to use option 1.
• only option 1 allows you to initialize reference members.
• only option 1 allows you to initialize const members
• only option 1 allows you to initialize base classes using their constructor
• only option 2 allows you to initialize array or structs that do not have a constructor.

My guess for why option 2 is more common is that option 1 is not well-known, neither are its advantages. Option 2's syntax feels more natural to the new C++ programmer.

You can have Read only or Read and Write only on the volume

docker -v /on/my/host/1:/on/the/container/1:ro \

docker -v /on/my/host/2:/on/the/container/2:rw \

data 52e - Returns when username is valid but password/credential is invalid.

You probably need something like

String dn = "cn=" + userName + "," + "CN=Users," + base;  

Add column to your migration file and run this command.

php artisan migrate:refresh --path=/database/migrations/your_file_name.php

In JavaScript there are two ways to create functions:

1. Function declaration:

   function fn(){
     console.log("Hello");
   }
   fn();
   

   This is very basic, self-explanatory, used in many languages and standard across C family of languages. We declared a function defined it and executed it by calling it.

   What you should be knowing is that functions are actually objects in JavaScript; internally we have created an object for above function and given it a name called fn or the reference to the object is stored in fn. Functions are objects in JavaScript; an instance of function is actually an object instance.

2. Function expression:

   var fn=function(){
     console.log("Hello");
   }
   fn();
   

   JavaScript has first-class functions, that is, create a function and assign it to a variable just like you create a string or number and assign it to a variable. Here, the fn variable is assigned to a function. The reason for this concept is functions are objects in JavaScript; fn is pointing to the object instance of the above function. We have initialized a function and assigned it to a variable. It's not executing the function and assigning the result.

Reference: JavaScript function declaration syntax: var fn = function() {} vs function fn() {}

According to the javadoc a Scanner does not seem to be intended for reading single characters. You attach a Scanner to an InputStream (or something else) and it parses the input for you. It also can strip of unwanted characters. So you can read numbers, lines, etc. easily. When you need only the characters from your input, use a InputStreamReader for example.

In Android Studio, go to app -> src -> main -> java -> com.example.username.projectname

Right click on com.example.username.projectname -> Activity -> ActivityType

Fill in the details of the New Android Activity and click Finish.

Viola! new activity added to the existing project.

In Android studio, Edit -- > Find --> Replace in path, this will check in whole project including comments and code.

I had the same issue. after adding below code to my app.js file it fixed.

var cors = require('cors')
app.use(cors());

There are few named constructors in GridView for different scenarios,

Constructors

1. GridView
2. GridView.builder
3. GridView.count
4. GridView.custom
5. GridView.extent

Below is a example of GridView constructor:

import 'package:flutter/material.dart';

void main() => runApp(
  MaterialApp(
    home: ExampleGrid(),
  ),
);

class ExampleGrid extends StatelessWidget {
  List<String> images = [

  ];
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: GridView(
        physics: BouncingScrollPhysics(), // if you want IOS bouncing effect, otherwise remove this line
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),//change the number as you want
        children: images.map((url) {
          return Card(child: Image.network(url));
        }).toList(),
      ),
    );
  }
}

If you want your GridView items to be dynamic according to the content, you can few lines to do that but the simplest way to use StaggeredGridView package. I have provided an answer with example here.

Below is an example for a GridView.count:

import 'package:flutter/material.dart';

void main() => runApp(
      MaterialApp(
        home: ExampleGrid(),
      ),
    );

class ExampleGrid extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: GridView.count(
        crossAxisCount: 4,
        children: List.generate(40, (index) {
          return Card(
            child: Image.network("https://robohash.org/$index"),
          ); //robohash.org api provide you different images for any number you are giving
        }),
      ),
    );
  }
}

Screenshot for above snippet:

Example for a SliverGridView:

import 'package:flutter/material.dart';

void main() => runApp(
      MaterialApp(
        home: ExampleGrid(),
      ),
    );

class ExampleGrid extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: CustomScrollView(
        primary: false,
        slivers: <Widget>[
          SliverPadding(
            padding: const EdgeInsets.all(20.0),
            sliver: SliverGrid.count(
              crossAxisSpacing: 10.0,
              crossAxisCount: 2,
              children: List.generate(20, (index) {
                return Card(child: Image.network("https://robohash.org/$index"));
              }),
            ),
          ),
        ],
      )
    );
  }
}

Here is a simpler solution to list all files in a directory and to download it.

In your index.php file

<?php
$dir = "./";

$allFiles = scandir($dir);
$files = array_diff($allFiles, array('.', '..')); // To remove . and .. 

foreach($files as $file){
     echo "<a href='download.php?file=".$file."'>".$file."</a><br>";
}

The scandir() function list all files and directories inside the specified path. It works with both PHP 5 and PHP 7.

Now in the download.php

<?php
$filename = basename($_GET['file']);
// Specify file path.
$path = ''; // '/uplods/'
$download_file =  $path.$filename;

if(!empty($filename)){
    // Check file is exists on given path.
    if(file_exists($download_file))
    {
      header('Content-Disposition: attachment; filename=' . $filename);  
      readfile($download_file); 
      exit;
    }
    else
    {
      echo 'File does not exists on given path';
    }
 }

Pattern pattern = Pattern.compile("^[a-zA-Z0-9]*$");
Matcher matcher = pattern.matcher("Teststring123");
if(matcher.matches()) {
     // yay! alphanumeric!
}

The easiest way to set a min and max value to a seekbar for me: if you want values min=60 to max=180, this is equal to min=0 max=120. So in your seekbar xml set property:

android:max="120"

min will be always 0.

Now you only need to do what your are doing, add the amount to get your translated value in any change, in this case +60.

    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            int translatedProgress = progress + 60;
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
        }
    });

Be careful with the seekbar property android:progress, if you change the range you must recalculate your initial progress. If you want 50%, max/2, in my example 120/2 = 60;

You can use the is function

if( $('#cartContent').is(':empty') ) { }

or use the length

if( $('#cartContent:empty').length ) { }

Declare in your Model with

  [DataType(DataType.MultilineText)]
  public string urString { get; set; }

Then in .cshtml can make use of editor as below. you can make use of @cols and @rows for TextArea size

     @Html.EditorFor(model => model.urString, new { htmlAttributes = new { @class = "",@cols = 35, @rows = 3 } })

Thanks !

Your time string is similar to the time format in rfc 2822 (date format in email, http headers). You could parse it using only stdlib:

>>> from email.utils import parsedate_tz
>>> parsedate_tz('Tue Jun 22 07:46:22 EST 2010')
(2010, 6, 22, 7, 46, 22, 0, 1, -1, -18000)

See solutions that yield timezone-aware datetime objects for various Python versions: parsing date with timezone from an email.

In this format, EST is semantically equivalent to -0500. Though, in general, a timezone abbreviation is not enough, to identify a timezone uniquely.

You can also use Guava and do something like this:

// This method returns enum for a given string if it exists, otherwise it returns default enum.
private MyEnum getMyEnum(String enumName) {
  // It is better to return default instance of enum instead of null
  return hasMyEnum(enumName) ? MyEnum.valueOf(enumName) : MyEnum.DEFAULT;
}

// This method checks that enum for a given string exists.
private boolean hasMyEnum(String enumName) {
  return Iterables.any(Arrays.asList(MyEnum.values()), new Predicate<MyEnum>() {
    public boolean apply(MyEnum myEnum) {
      return myEnum.name().equals(enumName);
    }
  }); 
}

In second method I use guava (Google Guava) library which provides very useful Iterables class. Using the Iterables.any() method we can check if a given value exists in a list object. This method needs two parameters: a list and Predicate object. First I used Arrays.asList() method to create a list with all enums. After that I created new Predicate object which is used to check if a given element (enum in our case) satisfies the condition in apply method. If that happens, method Iterables.any() returns true value.

You can use TEXT like this as part of a concatenation

=TEXT(A1,"dd-mmm-yy") & " other string"

How to POST mixed data: File, String[], String in one request.

You can use only what you need.

private String doPOST(File file, String[] array, String name) {
    RestTemplate restTemplate = new RestTemplate(true);

    //add file
    LinkedMultiValueMap<String, Object> params = new LinkedMultiValueMap<>();
    params.add("file", new FileSystemResource(file));

    //add array
    UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl("https://my_url");
    for (String item : array) {
        builder.queryParam("array", item);
    }

    //add some String
    builder.queryParam("name", name);

    //another staff
    String result = "";
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity =
            new HttpEntity<>(params, headers);

    ResponseEntity<String> responseEntity = restTemplate.exchange(
            builder.build().encode().toUri(),
            HttpMethod.POST,
            requestEntity,
            String.class);

    HttpStatus statusCode = responseEntity.getStatusCode();
    if (statusCode == HttpStatus.ACCEPTED) {
        result = responseEntity.getBody();
    }
    return result;
}

The POST request will have File in its Body and next structure:

POST https://my_url?array=your_value1&array=your_value2&name=bob 

XMLSpy does that for you, although that's not free...

I believe that Liquid Xml Studio does it for you and is free, but I have not personally used it to create test data.

One convenient trick to entering elapsed times into Excel is to have two zeros and a colon before the number of minutes, details follow. For copy and paste operations into Excel without have to worry about formatting at all one can use the format 00:XX:XX where XX are two digits totaling < 60. In that case, Excel will echo 0:XX:XX in the cell contents displayed and store the data as 12:XX:XX AM. If one pastes data in a 00:XXX:XX format into Excel, or 00:XX:XX where either XX > 59 this will be converted into a fraction of a day.

For example, 00:121:12 becomes 0.0841666666666667, which if multiplied by the number of seconds in a day, 86,400, becomes 7272 s. Next, 00:21:12 would by default show 0:21:12 stored as 12:21:12 AM. Finally, 00:21:60 becomes 0.0152777777777778, also a fraction of a day.

This suggestion is made merely to avoid having to worry about specific formatting in Excel, and letting the program worry about it. Note, for Excel data internally formatted as 12:XX:XX AM one can only use certain Excel commands, for example, one can take an average. However, subtraction will only work when the result is a positive number. Such that converting times into seconds, fractions of a day, or other real number is suggested for access to more complete arithmetic operation coverage.

For example, if one has a column of mixed time formats, or times that are negative and will not display, if one changes the number formatting to General, all the times will be converted to fractions of a day.
